The Kaizen concept introduced to the world by Imai is a resource that can be used for improvement anywhere. The benefits of this concept are immense, especially for developing countries, as the investment costs considered zero or minimal. Thus, the concept has now spread to the East and the West with many academic studies. However, it is doubtful whether this concept has been used to the fullest as the concept is based on the Japanese socio-economic background. Furthermore, this concept emerges especially in a context where middle management is seen as the driving force. Similarly, a centralised thought pattern can be seen throughout East Asia. The mediation procedure is the way of thinking of Asians. That may be due to their inspiration from Buddhist philosophy from 5 B.C. onwards. This study aims to consider how the Kaizen concept adapts to different organisational structures. The study further explores what needs to be done at the middle management level to maximise the Kaizen concept. However, this study is limited to conceptualisation. Here especially, the triangular organisational structure model and the smooth curve are used for analysis. For in-depth analysis uses positive and negative skewness. This study revealed that the Kaizen concept is satisfied in different ways within tall, flat and symmetrical organisational structures. Accordingly, it became clear that the Kaizen concept in a symmetrical organisational structure would satisfy middle management. It was further demonstrated that the introduction of Kaizen as negative skew and positive skew in high and flat organisational structures, respectively, can satisfy it in middle management. Thus, it is clear that the concept of Kaizen has the potential to be more effective in introducing the organisational structure in particular than in general. However, since this conceptualisation is done more simply, I suggest that further mathematical analysis is appropriate for this.

This work is an analysis of English nominal structures in selected editorials of Thisday Newspaper. It aimed to analyze the structure of noun phrases in the editorial, examine the functions of the noun phrases identified in the editorials in which they occur, determine the form of noun phrase that is commonly used in the editorials of Thisday newspaper and to establish if the form of noun phrases as used in the editorials affect the understanding and interpretation of the editorials. To achieve these aims, the first nominal group in each of the paragraphs of the editorials was selected for analysis using the Experiential and Logical Function Model of Halliday’s Systemic Functional Grammar (SFG) theory. The analysis revealed that the nominal groups have both logical and experiential functions in the text. It, also, reveals that the form of the nominal group that is most commonly used in the editorials of Thisday newspaper is MH and MHQ. The study established that the frequency of nouns in the editorials indicate high information density, therefore, the presence of complex nominal group structures in the editorials indicate information density in such editorials. This high information density allows for higher understanding of the editorials. More so, the research shows that the use of modifiers in the nominal group structure helps the readers to gain fast and direct access to information transmitted in the editorials. Based on the analysis carried out, this study concludes that the forms of nominal groups used in the editorials as well as the frequency of their usage affect the understanding and interpretation of the editorials either positively or negatively depending on whether the form is complex and frequently used or not complex and frequently used as the case may be.

In this study, previous studies on effective school management were reviewed. An effective school administrator emphasizes success at school, creates a positive atmosphere at school, monitors students in terms of success and ethical values, and develops new strategies in teaching. Organizational culture in school encompasses rules, values, and beliefs. Acting in accordance with the mission and vision of the school contributes to the organizational culture. A positive relationship was found between organizational culture and motivation in effective schools. The main feature that distinguishes a school from other schools is the school culture. This culture is important in the formation of corporate identity. In a study on the future plans of school administrators regarding the solutions for existing problems in school management, it has been determined that the curriculum is renewed in schools, the number of theoretical lessons is reduced, the practical-skill lessons are increased, and innovative practices are included. Merit is important to give importance to career planning. One of the most important features of effective school management is the effective participation of teachers in school management. In order to ensure a high level of active participation, the effective school culture can be listed as valuing the ideas of teachers, justice, having competent managers, communication skills, sincerity, honesty, efficient working, and following the rules. In a study on effective school characteristics, the most important feature came to the fore as school success. The personality traits of the school principal have been another remarkable element of the effective school. Expertise and sense of duty are emphasized for teachers working in effective schools. Another feature of an effective school is that parents have strong school-family relations. The most important features of successful school culture are the selection of people who have managerial leadership qualities, constantly improve themselves and have high communication skills in effective school management.

Background: Chronic liver disease denotes the disease of the liver which lasts over a period of 6 months or more. The serum ascites albumin gradient (SAAG) is a formula that is used to assist in determining the etiology of ascites. It is also used in detecting ascites of portal hypertension in the adult population. We don’t have any research-based information regarding the correlation between serum ascites albumin gradient and endoscopic parameters of portal hypertension in chronic liver disease. Aim of the study: The aim of this study was to assess the correlation between serum ascites albumin gradient and endoscopic parameters of portal hypertension in chronic liver disease. Methods: This prospective observational study was conducted in the Department of Hepatology, BSMMU, Dhaka, Bangladesh during the period from January 2005 to December 2005. In total 50 patients with cirrhosis with ascites with high SAAG values (>1.1 gm/dl) were included as the study people. The age of the patients was 15 to 70 years. Both males and females were included in the study. All data were entered into a personal computer, thoroughly checked for any possible error, and then processed and analyzed by the SPSS program. The significance of the test was tested by the chi-square test. P-value of <0.05 was taken as statistically significant. Correlation analysis was done by the Pearson correlation test. Result: In this study, there were three SAAG groups. In SAAG group 1.10-1.49gm/dl, 53.33% of patients had mild grades of PNG, and 33.33% of patients had a severe grade of PNG. In the SAAG group, 1.50-1.99 gm/dl, 44.44% of patients had mild grade and 33.33% had a severe grade of PNG and in the SAAG group >2 gm/dl, 42.30% had mild grade and 49.99% had a severe grade of PNG. But there had not been any significant correlation among the groups regarding SAAG values and PHTN grades because the p-value was greater than 0.05. Conclusion: It was shown in this study that, oesophageal varices were present in 49 patients, sensitivity was 98%; portal hypertensive gastropathy in 44 patients, sensitivity 88%, and both oesophageal varices and gastropathy in 43 patients, sensitivity 86%. So high SAAG value can be used as an indicator of the presence of portal hypertensive changes especially oesophageal varices and gastropathy in the upper gastrointestinal tract. A weak positive correlation was found in this study between SAAG values and grades of oesophageal varices (r=0.358, p=0.011) and gastropathy (r-0.139, p--0.33) but no correlation was found between SAAG and gastric varices (p=0.4).

This research studied the negative effects of corrosion attack on steel reinforcement in a marine environment with a high concentration of salt (sodium chloride) by the use of exudate/resins that was applied directly to the steel reinforcement through coatings of different thicknesses and embedded in concrete beams, and checked for suitability as a corrosion protection agent. The maximum value obtained of flexural load tests for controlled is 26.65% as compared to the value of -18.23% and 26.4% for the corroded and coated samples were examined for comparison of the flexural strength test. The results showed lower deformation loads in controlled and coated specimens with reduced values over corroded specimens with higher deformation in comparison with reference ranges (controlled). The calculated mean differential and percentile values were checked (0.03kN and 0.23%), corrosion values (0.030kN and 0.21%) and coating values (0.02kN and 0.21%). The results showed that the effect of corrosion on the mechanical properties of reinforcing steel with a decrease in diameter reduced the average and percentage of samples corroded, while the controlled and coated samples showed a preserved state due to coating due to an increase in diameter different layer thickness with exudates/resin The cross-sectional area of reinforcing steel shows a different mean value and percentile value of the corroded value (0.01 mm and 0.02%) and the coated value (0.05 mm and 2.69%). Differentially, the calculated mean and percentage values of yield strength and tensile strength are (2.13 MPa and 0.97%) and (3.435 MPa and 0.08%) and were examined, the corroded values were (3.44 MPa and 0.86%) and (4.548 MPa and 0.08%), the values of coated are (2.13MPa and 0.97%) and (4.736MPa and 0.09%). From the data obtained and compared, the yield strength and tensile strength values of the corroded samples showed a decrease in the average and percentage values for load failure with lower load applications. Comparison ratios obtained for deformation the maximum values calculated for the mean and percentile values for the controlled were -0.6% against the corroded and closed values of 1.22% and -0.29%. The difference between the mean and percentage values obtained for the control was (0.02 and 0.91%), corroded values (0.02 and 0.93%), and coated values (0.02 and 0.91%). The maximum comparison value for the controlled sample was -31.32% compared to the corroded and coated samples of 63.75% and 31.6%, respectively. The mean differential and percentile values obtained for the controlled samples were (1.69% and 7.34%), corrosion values (1.2% and 17.55%) and coated values were 1.69% and 7.33%). In comparison, the corroded samples showed higher stress values and higher elongation rates, whereas the damaged state of coated samples was lower load and reduced elongation.

This study investigated the potential use Pycnanthus angolensis (African/false nutmeg) exudates/resin as inhibitive materials against corrosion of reinforcing steel founded in the high salinity region. The accelerated corrosion test is an impress current technique, an effective technique for examining the corrosion process of steel in concrete and for assessing damage to the concrete cover protection to the steel bar and mechanical properties if steel bar modifications. The maximum yields obtained from the controlled and coated samples were -110.49mV and -114.7mV, which indicate the relationship between corrosion potential and probability in the reference range 𝐸corr > −200mV; For uncoated samples, the maximum calculated value is -317.5mV, the result is within the reference value of the dependence between corrosion potential and probability of −350mV ≤ 𝐸corr ≤ −200mV indicates a high-value range of 10% or indicates the possibility of unsafe corrosion. The maximum value calculated from the concrete resistance of the controlled sample concrete is 34.33% as compared to the corroded and coated values of 36.6% and 58.32% and the maximum difference percentage of control is 0.4% compared to the corroded and coated value of 0.24% and 0.59%. The results of controlled samples coated with concrete resistance obtained the maximum mean values of 12.47kΩcm and 14.68kΩcm with a description of the value 10 < 𝜌 < 20 (low) compared to the corrosion value of 9.31kΩcm with Specifications 5 < 𝜌 < 10 (high). The calculated yield strength maximum percentage value of the controlled yield strength was 3.56% compared to the corroded and coated values -4.88% and 5.34% and the possible difference values of 0.49% controlled, 0.19% corroded, and 0.21% covered. The calculated maximum percentage of the controlled ultimate tensile strength is 3.34% relative to corrosion and the coating value is -5.02% and 5.41% and the possible difference value is 0.12% controlled, 0.11% corroded and 0.12% coated. The maximum calculated strain ration percentage for comparison checked up to -5.86% versus corroded 6.06% and coated -5.83% and different peak values checked up to 0.04%, corroded 0.0079%, and coated 0.08% The comparison results show that the low load carrying capacity is caused by the effect of corrosion attack on the uncoated (corroded) elements, which damage the reinforcing steel fibers, ribs, and passive formation and surface modification. The observed mean values for the coated samples were associated with the corrosion resistance potential to penetrate the reinforcing steel with the formation of a protective membrane; This attribute indicates the efficiency and effectiveness of the exudate/resin as an inhibitor against corrosive effects. of reinforced concrete structures exposed to the edges of strong, high salinity marine areas. The decrease of cross-sectional area in mean and percentage values indicates that the corrosion effect causes a decrease in diameter and cross-sectional area, fiber degradation, rib reduction and surface modification, while the exudate/resin-coated elements are validated in the work due to differences in coating thickness. For comparison the results obtained of unit rebar weight loss/gain steel showed a reduction of mean and percentile values for coatings from 0.063 kg to 0.05 kg and corrosion 29.17% to -20.97% and the aggregate results show that the corrosion effect causes a reduction in weight/reduction of the corroded sample compared to the percentile layer and an increase in mean, resulting in a slight increase in volumearound the layer thickness. This study shows the efficacy and effectiveness of exudate/resin as an anti-corrosion anti-corrosion material in reinforcing steel embedded in samples of concrete slabs exposed to induced corrosion.

The study examined the use and potency of extruded exudates/resins obtained from tree trunks. The gummy exudates/resins were applied directly to the steel reinforcement by the coatings varying their thicknesses and embeddings them into concrete beams, and studying their possible effects as an inhibitor to corrosion attacks on reinforcing steel of concrete structures built within the coastal marine region with highly acidic nature. From the flexural strength test, the maximum value was 24.64% compared to the corroded and coated sample values of -18.46% and 24.41%, respectively and the average differential and percentile range controlled (2.25kN and 2.01%), corroded (0.66kN and 1.16%), coated (2.09kN and 1.77%). The results illustrated that the reference percentage of controlled samples according to [30] was placed in fresh water and no corrosion effect was observed and was therefore used as a reference value for uncoated and coated samples immersed in a corrosive environment as described in the test program. The calculated average differential and percentile values were checked (0.01mm and 0.009%), corrosion values (0.01mm and 0.063%) and closed values (0.01mm and 0.069%). The results illustrated the effect of corrosion on the mechanical properties of reinforcing steel with a decrease in diameter, as well as a decrease in the average value and the percentage recorded from the corrosion samples, while the controlled and coated samples illustrated preserved conditions with increasing layers of different diameters of exudates/resin layer thickness. The cross-sectional area of reinforcing steel after corrosion test gives different average and percentile values of corroded values (0.02 mm and 4.84%) and coated values (0.03 mm and 1.57%). The calculated maximum comparative values for both yield and ultimate tensile strength for the controlled samples were 9.66% and 3.54% to the corroded and coated values of -7.45% and -3.7%, coated values are 9.66% and 3.86%, respectively. From the data obtained and compared, the yield strength and ultimate tensile strength values of the corroded samples illustrated a decrease in the average and percentage values for load failure with few applications. The average differential and percentile values obtained for the control were (0.01 and 1.4%), corrosion values (0.02 and 1.54%), and closed values (0.01 and 1.4%). The maximum elongation comparative value for the controlled sample was -12.92% compared to the corroded and coated sample of 20.62% and -23.82%, respectively. The average differential and percentile values obtained for the controlled samples were (0.83% and 0.77%), corrosion values (0.82% and 1.38%), and coated values (0.82% and 0.78%). In comparative, the corroded samples illustrated higher stress values and higher elongation rates, whereas the damaged state of coated samples was lower load and reduced elongation. The calculated data illustrated a decrease in the value of the corroded sample as a result of the corrosion attack, which led to a decrease in the registered weight, whereas the coated sample illustrated an increase in weight compared to the reference value of the controlled sample due to the different coating thicknesses.

Background: Psychiatric symptoms which constitute a major and growing public health problem of anxiety, depression, and cognitive dysfunction often occur in patients suffering from somatic conditions like asthma and chronic obstructive pulmonary disease (COPD). In Bangladesh, we have very little research-oriented information regarding these issues. Aim of the study: The aim of this study was to determine the association of anxiety and depression with asthma and COPD. Methods: This cross-sectional observational study was conducted at the Department of Respiratory Medicine in the National Institute of Diseases of the Chest and Hospital from March 2018 to February 2019. A total of 160 cases of Asthma and COPD were enrolled in this study as study. Statistical analyses of the results were obtained by using Windows-based computer software devised with Statistical Packages for Social Sciences (SPSS-23.0). Results: In this study in total 98 (61.3%) patients had COPD and 62 (38.7%) had asthma. Among 98 COPD patients 10 (10.2%) had mild, 29 (29.6%) had moderate, 40 (40.8%) had severe and 19 (19.4%) had very severe COPD. Among 62 asthmatic patients 22 (35.5%) had mild, 16 (25.8%) had moderate, 11 (17.7%) had severe and 13 (21.0%) had very severe asthma. Among total participants, the mean Beck depression inventory score was found 95.6±12.6, the mean anxiety rating scale score was found 61.0±11.7 and the mean HADS score was found 12.1±1.5. In COPD patients, the mean Beck depression inventory score was found at 99.9±10.7, the mean anxiety rating scale score was found 57.1±10.7 and the mean HADS score was found 11.8±1.3. On the other hand, in asthmatic patients, the mean Beck depression inventory score was found 88.8±12.4, the mean anxiety rating scale score was found 67.4±10.3 and the mean HADS score was found 12.6±1.7. Conclusion: We can conclude that the Beck depression inventory score, anxiety rating scale score, and HADS score were statistically significant when compared to the level of severity of COPD and asthma. Excluding other risk factors for anxiety and depression, still, COPD & asthma patients remain at risk of both anxiety and depression.

The research evaluated the potential occurrence of corrosion in an induced media assessing the coating of reinforcing steel with Boswellia dalzielii (Burseraceae) exudates/resin gotten from the trunk of trees, the coating varies in thicknesses, embedded in concrete slabs, and exposed to the high severed coastal marine environment with acidic content. The maximum stability value calculated concrete resistivity from the controlled concrete sample was 63.55% compared to the corroded and coated values -44.28% and 84.61%, and the maximum controlled differential percentile was 2.8% compared to the corroded and 1.55% values and 5.53% coverage. The test results of controlled and coated samples with concrete resistance got a maximum average value of 14.38kΩcm and 16.28kΩcm with a value of 10 <𝜌 <20 (low) compared to a corrosion value of 8.85kΩcm with an indication of 5 < 10 (high) and the reference range of the relationship between concrete resistance and corrosion probability. The maximum obtained and corrosion potential values of the controlled and coated samples were -107.3mV and -121.5mV, indicating the relationship between corrosion potential and probability as 𝐸corr > −200mV as the reference range. The results of this potential Ecorr result show that the value of controlled and resin-coated samples is low with a 90% probability that no corrosion of reinforcing steel is observed during the measurement (10% risk of corrosion, which averages 10% for samples without coating obtained maximum value - 341.7mV, the result lies in the correlation reference value between the corrosion potential value −350mV ≤ 𝐸corr ≤ −200mV indicating a high range of values. The calculated maximum percentile ultimate tensile strength of controlled tensile strength is 2.06% compared to corrosion and coating values of 1.96% and 2.05%, and the possible differential values are 0.06% controlled, 0.01% corroded and 0.03 % coated. The calculated maximum percentile yield strength value of the controlled shear strength is 8.28% compared to the corroded and coated values of -7.61% and 8.28% and the controlled potential differential values are 0.05%, corrosion is 0.04% and 0.05% coated. The comparison results show that the low load carrying capacity is caused by the effect of corrosion attack on the exposed (corroded) elements, which damage reinforcing steel fibers, ribs and passive formations and surface modifications. The avearge values observed for the coated samples relate to the corrosion resistance potential to penetrate the reinforcing steel to form a protective membrane; This attribute indicates the effectiveness and effectiveness of the exudate/resin as an inhibitor against corrosive effects. exposed reinforced concrete structure on the edge of a strong sea area with high salinity. The maximum calculated percentile of corroded is 0.396% versus -1.17% and coated is 0.721%, the differential in the percentile of corrosion is 0.03% versus 0.003% coated. For comparison, the results of corroded samples showed reduction and reduction values compared to the diameter of the reinforcement before and after accelerated induction corrosion testing with a percentile decrease in value from 0.396% to -1.17% and an average value in the range of 11.93mm to 11.93mm. The differential in average and relative percentile between coated and corroded samples varied from 26.42% to -20.9%. The decrease in average and percentile values indicates that the corrosion effect has led to a reduction in diameter and cross-sectional area, fiber degradation, rib reduction and surface modification, while elements coated with exudates/resin confirm an increase in volume as thickness as there are shift differentials.
