The external nose, as a central anatomical feature of the face, carries significant aesthetic weight in the perception of facial harmony. The external structure of the nose, which is divided into nine aesthetic nasal subunits and six aesthetic nasal segments, presents a complex interplay of shapes and proportions that are critical to the overall appearance of the face. Given the significant role that the nose plays in facial aesthetics, it is important to understand how variations in nasal anatomy influence perceptions of beauty. The anatomical complexity of the nose is highlighted by the division into upper bony, middle, and lower cartilaginous vaults, each supplied by the facial artery and contributing uniquely to its appearance. For instance, the lower nasal base, lacking cartilaginous support, relies on skin, subcutaneous tissue, and nasal muscles to maintain its shape, highlighting the importance of a surgeon's understanding of these soft tissue components during aesthetic procedures. In the clinical or cosmetic evaluation of the external nose, palpation serves as a critical component, providing insight into underlying structural integrity and abnormalities that may not be immediately apparent through visual inspection alone. This tactile examination commences with an assessment of tip support, where the surgeon carefully applies pressure to determine the resilience and strength of the nasal tip, which plays a pivotal role in the overall appearance and function of the nose. In the meticulous analysis of the external nose, particularly when assessing the functional aspect, computer-assisted rhinomanometry has emerged as a critical tool. This technique, which is reliant on the recording of pressure differential and airflow, is essential in quantifying the degree of nasal obstruction, contributing significantly to the decision-making process in managing nasal deformities. This paper aims to explore the anatomical features of the external nose and their relationship to beauty standards, with a particular focus on understanding how variations in nasal shape and size influence perceptions of beauty. By examining the key anatomical structures of the external nose, we can gain a deeper understanding of the factors that contribute to facial aesthetics and how these standards vary across different cultures.

In this study, immunohistochemical expression of Her2/neu marker is correlated to various clinicopathological variables like age, gender, tumor size, grade, stage of the tumor.

Background: Adolescence is a critical transitional phase marked by developmental and social changes, often accompanied by behavioral challenges. Aggressive behavior during this period poses significant risks, including academic failure, social maladjustment, and long-term negative behavioral patterns. The study aimed to assess the risk factors which are associated with aggressive behavior among adolescents in Bangladesh. Methods: A cross-sectional study was conducted among 103 adolescents from Shahid Abdur Rab Serniabat Government Secondary School, Rupatoli, Barishal, using a convenient sampling technique. Data collection involved a self-reported questionnaire comprising two sections: 1) Demographic Information and 2) the Buss-Perry Aggression Questionnaire (BPAQ). Statistical analyses, including descriptive and inferential statistics, were performed using SPSS 25. Results: The mean aggression score among adolescents was (M = 2.70, SD = 0.62), reflecting average levels of aggression. Significant relationships were found between monthly family income (r = 0.19, p = 0.04) and the number of siblings (r = -0.62, p = 0.04) and aggressive behavior. Adolescents from families with higher monthly incomes exhibited higher aggression scores, whereas those with a greater number of siblings demonstrated lower aggression scores. Conclusion: The findings of this study provide insights into the risk factors associated with aggressive behavior among adolescents. These results can inform the development of targeted strategies to mitigate behavioral problems and support health education initiatives aimed at addressing the impact of aggression in this vulnerable age group.

This study successfully synthesized SnO2 nanoparticles via co-precipitation and subsequently loaded them with varying weight percentages (1-4%) of graphene oxide (GO) using a hydrothermal method. The resulting GO/SnO2 nanocomposites were comprehensively characterized using a suite of spectroscopic techniques, including SEM, TEM, XRD, elemental mapping, EDX, FT-IR, BET, PL, UV-Vis, and DRS. These analyses confirmed the successful formation of the desired nanostructures. Furthermore, the photocatalytic performance of the nanocomposites and pure SnO2 was evaluated by monitoring the photodegradation of methylene blue under visible light irradiation, demonstrating the impact of GO loading on photocatalytic activity. The degradation efficiencies of the GO/SnO2 were much higher than that of pure SnO2. From the results obtained, we believe that this current study will provide relevant views for further fabrication of other novel nanostructures and exploration of their potential carcinogenic and environmental consequences.

Background: Abruptio placenta is a major cause of massive obstetric hemorrhage and significant cause of maternal and neonatal morbidity and mortality worldwide and in developing countries including India. This study aimed to determine risk factors for abruptio placenta and subsequent feto-maternal outcome at a tertiary care center (hospital). Methods: A prospective study was conducted at department of obstetrics and gynaecology, RIMS Adilabad. All patients diagnosed with abruptio placenta clinically and/or sonographically were included in the study. The maternal complications and fetal outcome were analyzed in detail. Results: In this study, 82 women were diagnosed with abruption placenta. Incidence of abruptio placenta is 1.4% at our institute. Most patients in our study are multiparous (64.6%), un booked (31.7%) and are in the age group of 20-30 years (58.5%). In our study abruption placenta was mostly associated with PIH/Hypertensive disorders of pregnancy (56.09%). H/o abruption placenta in previous pregnancy (12.19%), Idiopathic (23.17%), Trauma (2.4%), PROM (2.4%) are other risk factors associated with abruptio placenta. Anemia is associated with 58% of cases. Majority (54.8%) of cases delivered vaginally, 45.12% patients were delivered by LSCS. 63.14% babies were live born, 23.17% were IUD, 13.4% were stillborn. Post partum hemorrhage (19.5%), Acute renal failure (17.7%), disseminated intravascular coagulation (15.8%) are important maternal complications. Maternal mortality rate is 2.4%. Perinatal mortality is 25.6%. Conclusion: Abruption placenta is associated with poor maternal and fetal outcome. There is need to spread awareness regarding taking adequate antenatal care so that associated risk factors could be diagnosed early and treated adequately. Prompt resuscitative measures and expedition of delivery process after abruption favours good fetomaternal outcome.

The purpose of this paper is to analyze the emergence process or a new paradigm in the theory and practice of knowledge management. It is the paradigm of artificial knowledge. This new paradigm changes the semantic spectrum of the concept of knowledge as it has been used so far in knowledge management systems. Artificial knowledge is completely differentiated from human knowledge and can no longer be considered a justified true belief. Artificial knowledge is a product of artificial intelligence technology. The paper performs a semantic analysis of the new concept and its features by comparison with human knowledge. Also, the paper presents a bibliometric analysis of the most significant publications discussing artificial knowledge and artificial intelligence. The bibliometric analysis is done using VOS viewer, a specialized software program for such research. The present paper shows that researchers in knowledge management face the emergence of a new paradigm.

This work presents the successful deposition of H. Sabdariffa(Zobo) dye-doped ZnS thin films with different volumes of Zn2+ solutions on cleaned glass substrate slides using inexpensive chemical spray-pyrolysis technique with the substrates kept at a constant temperature of 200oC. The final spray solution for the growth of the films contained aqueous solutions of ZnSO4.7H2O, SC(NH2)2, and H.Sabdariffa dye extracts. ZnSO4.7H2O and SC(NH2)2 served as precursors for Zn2+ and S2- respectively while H.Sabdariffa was used as dye. The sprayed film properties were characterized for optical properties using a HINOTEK 756S UV-VIS spectrophotometer. From the absorbance’s spectral analysis, other optical parameters such as transmittance, reflectance, absorption coefficient, band gap energy and optical density were calculated. The films indicated high absorbance in the UV region and high transmittance in the VIS – NIR regions, whereas reflectance is generally low. The films indicated direct band gap energy range of 2.10eV to 2.62eV. The optical density indicated range of 0.5 to 6.16. Based on relatively low reflection, strong absorption in UV region, high transmission and wide band gap indicated by the films. Therefore, it can be concluded that the films are suitable for the fabrication of solar cells. Also, the films are good for anti-dazzling coatings and thermal control coatings in automotive and architectural industries respectively.

Background: Breast cancer is a significant global health concern, with its incidence steadily rising in both developed and developing nations. It is the leading cause of cancer-related deaths among women, accounting for 16% of cancer fatalities in adult females. This study aimed to assess the level of breast cancer knowledge among nurses working at a tertiary-level hospital in Barishal. Methodology: A cross-sectional study was conducted among 266 nurses at Sher-E-Bangla Medical College Hospital, Barishal. A convenient sampling technique was applied, and data were collected using a self-structured questionnaire developed through an extensive literature review. Data analysis was performed using SPSS-23, employing both descriptive and inferential statistics. Results: Nearly 97% of nurses recognized breast cancer as a life-threatening disease, while more than half (61%) disagreed with the notion that breast cancer is preventable. The overall mean knowledge score on breast cancer was 3.75 (SD = 0.40), indicating an average to moderate level of knowledge. Marital status (t = -2.84, p<0.05) was found to have a statistically significant association with breast cancer knowledge, with married nurses demonstrating higher awareness than their single counterparts. Additionally, significant differences in knowledge levels were observed between Muslim and non-Muslim nurses, with non-Muslim nurses exhibiting greater awareness of breast cancer. Conclusion: The findings of this study provide valuable insights into the level of breast cancer knowledge among nurses at a tertiary-level hospital in Barishal. The results can serve as a guide for improving nurses' understanding of breast cancer and developing strategies to reduce associated risks. Furthermore, these findings emphasize the need for health education programs aimed at raising awareness and disseminating crucial information on breast cancer prevention and early detection.

Digestive haemorrhage (HD) is a frequent reason for consultation at the Emergency Department. Approximately 80% of GI haemorrhages are upper GI, i.e. related to a lesion located above the angle of Treitz. The main causes are ulcer disease, portal hypertension, gastritis and ulcerated lesions of the stomach, and reflux oesophagitis. In approximately 10% of cases, a rarer cause (Mallory-Weiss, acquired vascular malformations, Dieulafoy, primary PAEF or secondary aortodigestive fistulas, biliary or pancreatic tract anomalies, tumours,...) is responsible. We report the case of a patient with high HD in whom aortoduodenal fistula was the cause diagnosed on abdominal CT.

Organizational culture is an important element for a company. Habits are created because of the communication that occurs between employees. Every employee should have the motivation to work. However, in reality, quite a few employees lose direction when doing their work. Therefore, the problem in this research is whether organizational culture and work motivation influence employee performance, either partially or simultaneously. This research aims to analyze the influence of organizational culture and work motivation on employee performance at NCTA partially and simultaneously. The population in this study were all NCTA employees, especially the general bureau, while the sample was obtained using the Slovin formula, 63 people. The data analysis method used is the descriptive percentage analysis method, multiple linear regression analysis method with partial test hypothesis testing (t), simultaneous test (F), and coefficient of determination. The conclusion obtained is that organizational culture and work motivation have a partial positive and significant influence on employee performance. Simultaneously, it can also be concluded that organizational culture and work motivation have a positive and significant influence on employee performance. This research also states that organizational culture and work motivation influence employee performance simultaneously by 52.3%.
