Purpose: This study aimed to examine the level of acculturative stress, career stress, social support and depression, and identify factors affecting depression among Korean international students in China. Methods: Data were collected from 157 Korean students studying in undergraduate, graduate, students exchange programs and language training courses in G university, J university, and S university in G city, Guangdong Province, China, from September 1 to October 27, 2017. The data were analyzed with descriptive statistics, t-test, ANOVA, and multiple linear regression. Results: The mean acculturative stress was 62.24±18.08 out of 165, whereas the mean career stress was 65.47±19.79 out of 125. The mean social support was 95.03±14.64 out of 125, and the mean depression score was 13.83±9.24 out of 60. The factor that had the greatest effect on depression among the participants was acculturative stress (β=.26, p=.001), followed by career stress (β=.24, p=.002), frequency of weekly phone calls with family (β=.19, p=.006), source of tuition payment (β=.18, p=.009), and self-perceived health (β=.15, p=.040). The model explained 33% of the variance. Conclusion It is necessary to develop depression prevention and management programs as well as a customized health promotion program that account for the factors identified to have an effect on depression, namely, acculturative stress, career stress, frequency of weekly phone calls with family, source of tuition payment, and self-perceived health, and increase awareness of depression among international students.

BACKGROUND: Airway obstruction due to blood clot occurs unusually but in a variety of clinical settings. Initial efforts for removal of the endobronchial blood clot involve flexible bronchoscopic evaluation with saline lavage and suctioning and then forceps extraction. If unsuccessful, further options include rigid bronchoscopy, Fogarty catheter dislogement of the clot, and topical thrombolytic agents. The several successful uses of endobronchial streptokinase or urokinase to dissolve an endobronchial blood clot have been previously reported, but not yet in Korea. Herein we describe a 51-year old man with superior vena cava thrombosis secondary to Behcet's disease who experienced life threatening airway obstruction after hemoptysis due to a large organized blood clot in left main bronchus. Urokinase(260,000 U), injected through a fiberoptic bronchoscope, totally dissolved the clot. No complications occured.

Background: Lymph node fine-needle aspiration (LN FNA) cytology indicates necrosis in various diseases. Dominant necrotic features make the diagnosis of underlying conditions very difficult. Methods: We retrospectively reviewed 460 patients who underwent cervical LN aspiration cytology that revealed necrotic findings at Keimyung University Dongsan Hospital in Daegu, Korea, from 2003–2017. Each specimen was evaluated and analyzed in association with the clinical findings, biopsy findings, and/or other ancillary tests, including acid-fast bacilli staining and molecular testing for Mycobacterium tuberculosis. Results: When necrotic features were noted upon cervical LN FNA cytology, the most common pathologic LN FNA category was necrosis alone (31.5%). The second most common category was granulomatous inflammation (31.3%), followed by Kikuchi disease (20.0%) and malignant neoplasm (8.7%). In cases where the cervical LN FNA revealed necrosis alone, the most common final diagnosis was tuberculosis. In young patients, Kikuchi disease should be considered as one cervical LN FNA category, while metastatic carcinoma should be suspected in older patients. Conclusions Even when necrosis alone is observed in LN FNA cytology, it is important to determine the cause through further evaluation.

OBJECTIVE: To investigate whether polymorphism of gene encoding COMT is associated with the risk of endometriosis in Korean women. METHODS: We investigated 136 patients with histopathologically confirmed endometriosis rAFS stage III/IV and 251 control group women who were surgically proven to have no endometriosis. Polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) of PCR products were done to determine each participant's COMT genotype. RESULTS: The distribution according to NIaIII genetic polymorphisms of COMT were as follows. COMT HH, COMT HL, and COMT LL genotypes were 56.6% (77 women), 34.6% (47 women) and 8.8% (12 women) in the study group and 50.6% (127 women), 39.4% (99 women) and 10.0% (25 women) in the control group. There was no significant difference between the study group and the control group. CONCLUSION: The results suggest that COMT genetic polymorphism may not be associated with the development of endometriosis in Korean women.

OBJECTIVES: This study was to investigate mean Z-score of BMD of Korean premenopausal women and also to investigate the relationship between BMD and body composition, such as skeletal muscle (SM) mass, body fat mass, and abdominal adiposity among healthy Korean premenopausal women in their forties. METHODS: A total of 2711 premenopausal women in her forties (40-49 years) who had taken dual energy X-ray absorptiometry (DXA) for BMD screening and body composition analyser (InBody J10®) from 2012 to 2013 at health promotion center of Ewha Womans university Mokdong hospital were analyzed retrospectively. Demographic data such as body mass index (BMI), waist circumference (WC), hip circumference (HC), waist hip ratio (WHR), SM mass, body fat mass, and serum lipid profile were included in this study. The Pearson's correlation coefficient (CC) was used to identify co-efficiency between BMD and other parameters. RESULTS: The mean age was 44.2 ± 4.44 (years) and mean BMI was 22.43 ± 2.99 (kg/m2). Mean Z-score of BMD-lumbar 1-4 (BMD-L) and BMD-femur total hip (BMD-F) was 0.33 ± 1.14 and -0.19 ± 0.85. Mean of BMD-L and BMD-F were 1.18 ± 0.16 (g/cm2) and 0.96 ± 0.12 (g/cm2). Skeletal muscle mass showed a strong significant correlation coefficient (CC) only with BMD-F (CC = 0.13, p-value = 4.78 × 10(-11)). However serum lipid profile, body fat mass, and WHR did not show significant CC with mean Z-score of BMD-F and BMD-L. CONCLUSION: Skeletal muscle mass measured by body composition analyzer of BIA method is a strong correlation factor for BMD especially of hip bone among healthy Korean premenopausal women in their forties.

Nevoid melanoma is a very rare histological subtype of vertical growth phase melanoma. Histologically, it mimics benign nevus and thus may lead to an erroneous diagnosis. We report a case of nevoid melanoma arising in a 53-year-old American woman. High index of suspicion and evaluation of cytologic atypia with ancillary tests may help in establishing the diagnosis.

Nutrition during childhood is essential for growth and maintenance of health. Good food habits developed during the childhood will contribute both to the healthy growth and the prevention of the degenerative disease of later life. Both parents and the providers in child care centers play an important role for children's good eating behavior. Therefore all child care programs should achieve recommended standards for meeting children's nutritional and educational needs in a safe, sanitary, and supportive environment to promote the healthy growth and development of children. The purposes of this study were to evaluate the foodservice management practices and assess the needs for a Central Production Unit by contacting the child care center' providers. This approach was achieved using a variety of qualitative and quantitative information including the general foodservice management practices and the needs for a Central Production Unit. An indepth face-to-face interview with structured-questionnaires was undertaken at 32 representative child-care centers in Seoul. Statistical data analysis was done using the SAS program for descriptive analysis and ANOVA. The number of national/public and private sectors were 11 respectively, followed by 10 licensed home day-care centers. Total average number of children in child-care centers was 54.3+/-48.5. The foodservice productivity index in child-care centers was 4.8 minutes per meal for public child care centers, 6.0 for private child-care centers, and 9.8 for home child care centers. Home child care centers were found to have the lowest productivity index which indicated inefficient foodservice practice. The important factors in group purchasing were menus(39.6%) or close distance(39.6%) > type of foodservice operation(32.8%) > total number of meals(19.9%) > food costs(16.2%) in order. Average score of the efficiency for central food production in child-care centers was 3.80+/-0.84 out of 5.
