Objective: The Internet is an essential component for providing current and up to date information in education. Despite the significant advantages, abuse of internet results in Internet addiction (IA) disorder. The present study aims to determine the level of IA and internet behavior pattern among medical and university students in Bangladesh. Methods: This cross-sectional study was carried out among 379 students in Bangladesh from one private medical college and one private university of Chittagong during the study period from 2017 to 2018. Analysis for throughput, "Young's IA test (IAT)'' was used. Data were analyzed using SPSS version 21. Cronbach's alpha coefficient, the independent t-test and oneway analysis of variance (ANOVA) were utilized and P<0.05 as significant. Results: The mean± SD of "IAT" score was 47.97±13.61. Cronbach's alpha coefficient was 0.83. The majority (54.88%) of the participants was "mild user''. The majority (63.39%) of the medical students was "mild user,'' and the majority (61.60%) of the university students were "moderate user." Statistically, a significant difference was found between "IAT" score and "Duration of internet use" of the medical and university students (p = 0.00). A significant difference was observed between age, sex, and IA. The majority (86.61%) of medical students used the internet for social networking, and the majority (71.2%) of university students used the internet for education purpose. Maximum participants use "Smartphone" and "mobile 3G" and had an email address and a social network account. Conclusions: Early detection of internet dependence could help to take appropriate steps to tackle the growing problem of IA.
Background : Anthropometry is the study of human morphology. Physical variation between the people of different ethnic groups can be recorded by anthropometry. This study was done to establish the anthropometric difference by measuring the nasal parameters among Bengali and Chakma School Going Children. The data of nasal parameters provide important information in plastic surgery, aesthetics and, nationality study and medical jurisprudence. Methods : It was an observational and cross sectional study, convenient sampling was done to select the 50 Bengali and 50 Chakma School Going Children, age ranging from 5-16 yrs old. Data were collected by using standard anthropometric methods with a sliding caliper. Values were expressed as mean ± Standard Deviation (SD).Student T test was used to compare the results. Results : In both sex, among the two ethnic groups, the mean total length and protrusion of nose in the Bengali group was significantly (<0.001) higher than the Chakma ethnicity (48.46±6.75 vs 41.34±4.17, 16.77±2.85 vs 14.48 ±2.22). The mean anatomic width of the nose was higher in Chakma ethnic group. The mean nasal index in the Bengali ethnic group was 67.60 and in the Chakma was 83.38 which shows that the mean nasal index of most Bengali (68%) falls within the Leptorrhine (Narrow nose) type and the most Chakma ethnicity (54%) in the mesorrhine (Broad nose) type. Conclusion : This result represent that the nasal parameters and index play an important role in the ethnicity difference.
Background: Foot is a complex, multi-segmented structure. Each segment act in a coordinated manner to provide support and absorb shock during locomotion. Foot morphology differs among population groups. The objectives of this study were to determine the selected foot dimensions and foot shape of adult Bangalee females to find out any ethnic characteristics of their own. Materials and methods: The study was conducted on 200 Bangalee adult females within 18-44 years age. Foot length and foot breadth were measured by slide caliper. Foot index was calculated from foot length and foot breadth. Foot shape was determined from foot index by using a pre determined formula. Results: The mean value for length, breadth and index of foot in Bangalee females were 22.91±0.79 cm, 8.55±0.4cm and 37.35±1.92 respectively. Most of the participants (68%) had standard foot shape. 17.5% women had slender foot whereas14% had broad foot shapes. Conclusion: The results of this study should be useful for anatomists, anthropologists and forensic experts. JCMCTA 2020 ; 31 (1) : 54-57
