PURPOSE: Occupational stress is a determinant risk factor for cardiovascular disease and work disability. This study aims to describe occupational stress and identify its related factors among aged security guards. METHODS: A random sample of 76 aged security guards were interviewed by three research assistants. The criteria of the subjects were as follows : 50 or older male with 40 or more working hours a week working with colleagues ranged from 3 to 50. The data were collected in September, 2007 and analyzed by multiple regression using SAS Version 9.1. RESULTS: The mean score of occupational stress among aged security guards was 47.2. The mean scores of its sub-scales were 31.3(physical environment), 33.8(occupational demand), 80.8occupational control), 44.6(interpersonal conflict), 51.3 (occupational insecurity), 53.6(occupational system), 57.5(lack of reward), and 30.3(work environment). The scores of occupational control, interpersonal conflict, and occupational insecurity were higher than the scores of Korean average occupational stress sub-scales. Significant variables affecting occupational stress and its sub-scales were work place, work type, and employment type. CONCLUSION: In order to reduce occupational stress among security guards, sufficient occupational control and interpersonal conflict control, appropriate reward, and employment stability should be considered. Also long working hours and work shift should be improved.

PURPOSE: The purpose of this study was to examine medical professionals' perception and knowledge of hospice and palliative care (HPC) and attitude toward death. METHODS: The survey was performed on 84 physicians and 172 nurses in Busan, Korea. Data were collected from April 5, 2012 to April 30, 2012. RESULTS: Regarding the purpose of HPC, the most popular perception was "To alleviate pain and accommodate comfort" among both physicians and nurses. For the need for HPC, "Terminal patients need a separate ward for emotional fluctuation" the answer chosen by both groups the most. Both groups scored low on knowledge of HPC. For pain and symptom management, physicians scored higher than nurses (physicians: 6.97+/-1.82, nurses: 5.68+/-1.93, P<0.001). CONCLUSION: Considering the survey results, we suggest development of a program to improve medical professionals' perception and knowledge of HPC and attitude toward death.

Plasmodium vivax malaria re-emerged in South Korea in 1993, and epidemics continue since then. We examined genetic variation in the region encompassing the apical membrane antigen-1 (PvAMA-1) of the parasites by DNA sequencing of the 22 re-emerging P. vivax isolates. The genotype of the PvAMA-1, which was based on sequence data previously reported for the polymorphic regions, showed that two haplotypes were present at one polymorphic site. Compared with reported data, the two types, SKOR type I and type II, were similar to Chinese CH-10A and CH-05A isolates, respectively. Thus, the present study showed that two genotypes of AMA-1 genes coexist in the re-emerging Korean P. vivax.

Purpose: Coronavirus Disease 2019 (COVID-19), an emerging infectious disease introduced in South Korea in 2020. Medically inclined college students are more susceptible to be infected by the virus. The purpose of this study was to investigate factors influencing preventive behavior against COVID-19 among medically inclined college students. Methods: This is a cross-sectional study using a questionnaire survey. Data were collected from 400 medically inclined college students from four colleges of medice. Independent t-test, one-way ANOVA, Pearson correlation coefficients and multiple regression analysis were conducted to analysis the data. Results: The study subjects had high knowledge and optimism related to COVID-19. Preventive behavior against COVID-19 was affected mostly by attitude (β=.32, p<.001). Such behavior was also high in relation to knowledge (β=.17, p<.001), and nursing students (β=.15, p=.002). Conclusion Infection prevention education for medically inclined college students mainly focuses on knowledge transfer. Infection preventive education programs aimed at improving COVID-19 optimistic attitudes and knowledge are helpful for these students to maintain appropriate preventive practices. The confirmation of the importance of optimistic attitudes and risk perception toward infectious diseases through this study can provide insight into infection prevention education programs to improve practice to wards new epidemic prevention behaviors.

Most of the malignant tumors of the pancreas are adenocarcinomas arising from the ductal epithelium. Primary leiomyosarcoma of the pancreas, even though it is the most common sarcoma of the pancreas, is very rare. We present a case of leiomyosarcoma of the pancreas, probably primary, with metastases to the stomach, lymph nodes, and abdominal wall. A 52-year-old woman visited the hospital with vague right upper abdominal pain and weigh loss of 6 kg for 2 months. The radiological and endoscopic examination revealed that she had a large heterogeneous mass, 11 cm in size, in the pancreatic body and tail, a 4 cm-sized mass in the paraaortic area, and a 3 cm-sized polypoid mass in the stomach. Histologically, they were all similar to one another and composed of markedly pleomorphic cells. Immunohistochemical and electron microscopic studies showed definite smooth muscle differentiation of the tumor cells. Two months later, the patient underwent an excision of a new 3 cm mass in the right lower abdominal wall, showing features of well differentiated leiomyosarcoma.
