Purpose: This study was to report our experience of the brief survey for teaching journal writing by medical students in a clinical curriculum of family medicine. Methods: Brief surveys performed by medical students in clinical clerkship of department of family medicine from 1998 to 2000. Medical students determined theme without rein for brief surveys. Lecture about meaning and process of survey was given for sufficient understanding of students, and then surveys were conducted. The subjects of survey were outpatients, nursing person, medical students, nursing students, and other general persons. The subjects of theme were classified to 17 chapters 7 components by international classification of primary care (ICPC). Results: In analysis of brief surveys according to ICPC, the reasons for surveys by components were diagnostic, screening prevention (89.0%), treatment, procedures, medication (5.7%), symptoms, complaints (5.3%). By chapters, there were social (64.6%), psychological (12.6%), metabolic and endocrine (6.5%). Among social problems, there were other social problem (35.4%), health care system/access (20.9%), problem with education (13.9%), relation problems partner (12.7%). Majority of medical students had affirmative response for survey conduction. In conclusion, our finding suggest that teaching journal writing as brief survey seems to be useful in understanding of journal writing of medical students.

연구배경: 최근 국제당뇨병연맹 (International Diabetes Federation, 이하 IDF)에서는 민족적 특성을 고려한 복부비만을 대사증후군의 필수 진단항목으로 설정하였다. 이에 비만학회에서는 한국인에서 복부비만 기준을 위한 허리둘레 분별점 설정 사업을 시행하였다. 방법: 체계적인 문헌 고찰 및 전문가 토론 과정을 거쳐 가장 적절한 도구로 분석 방법을 선정하였다. 분석자료로는 한국인을 대표할 수 있는 1998년도 국민건강영양조사 자료 (총 6,562명)를 이용하였으며, 분별점의 기준 지표로는 가장 최근에 제시된 IDF의 대사증후군 진단기준을 택하였다. Receiver Operating Characteristics (이하 ROC) curve를 통해 가장 적절한 분별점을 살펴보았으며, 교차비를 통해 대사 항목 2개 이상의 존재를 가장 잘 예측할 수 있는 수치를 구하였고, 얻어진 수치별로 복부비만의 유병률을 구하여 현재 국내의 실정에 가장 타당하다고 여겨지는 분별점을 정하였다. 결과: ROC 분석 결과, 높은 중성지방, 낮은 HDL-콜레스테롤, 높은 혈압, 높은 혈당 및 이러한 4가지 대사 이상을 예측하는 적정 허리둘레의 분별점은 대사 항목에 따라 남자에서는 82~84㎝, 여자에서는 79~82㎝의 범위를 보였다. 허리둘레 70㎝ 미만을 기준으로 교차비를 구한 결과, 허리둘레가 5㎝ 단위로 증가함에 따라 각각의 대사 항목 및 2개 이상 집합체의 교차비가 증가하는 경향을 나타내었다. 특히 대사 항목 2개 이상 집합체의 교차비가 5일 때의 허리둘레가 남자는 약 90㎝, 여자는 약 85㎝이었으며, 80백분위수에 해당하는 허리둘레는 남, 녀 각각 90.0㎝, 86.5㎝로 나타났다. 결론: 현재의 시점에서 사용 가능한 자료를 이용하여 분석, 고찰한 결과 한국인에서 복부비만의 기준을 위한 허리둘레 분별점은 남자에서 90㎝, 여자에서 85㎝로 나타났다. 따라서 남자에서 90㎝ 이상, 여자에서 85㎝ 이상일 때 복부비만으로 정의하는 것이 가장 적절할 것으로 보인다. Background: Recently, the International Diabetes Federation (IDF) consensus proposed a new definition for diagnosing metabolic syndrome. Ethnic-specific waist circumference (WC) cut-off points have been incorporated into the definition. Therefore, the study of the WC cut-off points for defining abdominal obesity in Koreans was performed by the Korean Society of the Study of Obesity. Methods: The data used for analysis was from the Korean National Health and Nutritional Examination Survey (KNHANES) performed in 1998 (involved 6562 participants), which is representative of nutritional health research in Korea. The 2005 International Diabetes Federation definition of the metabolic syndrome was applied. The reasonable cut-off points of WC for abdominal obesity in Koreans were set based on Receiver Operating Characteristics (ROC) curve, odds ratio and prevalence of abdominal obesity in the study population. Results: Using ROC analysis, the optimal WC to predict the risk factors of metabolic syndrome, such as high triglyceride levels, low levels of HDL-cholesterol, hypertension, and high glucose levels in Koreans, was 82~84㎝ for men, and 79~82㎝ for women. The odds ratio of having more than 2 metabolic abnormalities was about 5 in men with WC>90㎝ and in women with WC>80㎝. WC in the 80th percentile in the Korean population is 90㎝ and 86.5㎝ for men and women, respectively. Conclusions: The cut-off points of WC for abdominal obesity in Koreans are 90㎝ for men and 85㎝ for women, respectively. The cut-off points of waist circumference for defining abdominal obesity should be followed up by future additional studies and updated when new data becomes available.

Background: Obstructive sleep apnea (OSA) is considered to be associated with neurocognitive dysfunction, depression, quality of life and cardiovascular diseases. OSA is likely to have a significant impact on the health of older adults. This study was to identify characteristics of older adults with high risk for OSA according to age and gender. Methods: This study was conducted on adults aged 65 years or older who participated in the 8th Korea National Health and Nutrition Examination Survey (KNHANES) 2020. Characteristics of the high-risk group for OSA were investigated using the STOP-Bang questionnaire of the KNHANES data and were compared according to gender and age. The health status, metabolic variables, concurrent disease of the high risk group were compared with the control group. Results: In older adults aged 65 or older, snoring rates significantly decreased as their ages increased in both sex. The high risk group had a higher rate for performing strength exercise than control group. Depression showed a higher rate in the high risk group, but there was no difference in stress and quality of life in the two groups. The waist circumference and the prevalence of hypertension, stroke, dyslipidemia, diabetes, and metabolic syndrome was higher in the high-risk OSA group. Conclusion: It is unclear whether OSA-related symptoms increase with age in older adults over 65 years of age. Waist circumference was higher in the OSA high risk group, and this study showed that the OSA high risk group may be more likely to have metabolic syndrome and cardiovascular disease.

This study was conducted to analyze the strengths and weaknesses of a 3-week family medicine clerkship program based on the results of an online survey taken by the students (N=127) and a structured interview with a focus group (n=10), aimed to improve the quality of the clerkship program. The online survey contained questions pertaining to goals, schedule, contents, arrangement, atmosphere, environment, evaluation, and satisfaction regarding the clerkship. The focus group interview addressed the schedule and achievements of the program. Scores were reported on a 5-point Likert scale. Most students were highly satisfied with the overall quality of the clerkship. The structured interview results showed that 97.6% of the clerkship program was executed according to the schedule. The focus group reported a perfect score of 5 points on several measures including: accomplishment of the educational goals of the family medicine clerkship, providing many chances to obtain medical histories and perform physical examinations on real patients, experience with various symptoms and diseases, positive attitudes of faculty members when teaching, notification of the guidelines for evaluation beforehand, well-constructed and effective clerkship schedule, and reflection of student feedback. However, the focus group gave low scores on: support for health accidents of students, access to patient information, enough opportunities to practice clinical skills, appropriate rest facilities for students, and fairness of clerkship evaluation process. In conclusion, the structured evaluation performed after the 3-week clerkship program motivated students and helped them ensure an efficient clerkship. This structured evaluation also suggested basic data to make the professor who is subject of the assessment. This study shows that structured assessment is an effective method which can be used to improve the quality of clerkships.

The purpose of this study was to assess third-year medical students' competency for development or revision of the undergraduate curriculum and assessments. One hundred and twenty-seven third-year medical students at the Pusan National University were included in the study. After third- and fourth-year students took a common written examination, clinical performance examination (CPX), and objective structured clinical examination (OSCE) with common items as a summative assessment, the third-year students' competency was compared with 132 forth-year students' results. The correlation of the written examination and CPX/OSCE was analysed, and the summative results were compared with the grade point average (GPA) through the second year, CPX/ OSCE in the second year, and GPA in the clerkship. On the written examination, the third-year students' mean score was lower than the fourth-year students' by over 11 points, whereas the gap in the CPX/OSCE was 4 points and there was no difference in the OSCE. There was a moderate correlation between the written examination and the CPX/OSCE scores (R=0.371, p<0.01). The written examination was highly correlated with GPA through the second year, which mainly evaluated medical knowledge (R=0.771, p<0.01). A relatively high correlation was observed between CPX/OSCE scores and GPA in the clerkship (R=0.641, p<0.01). The summative CPX/ OSCE scores showed a moderate correlation with formative CPX/OSCE scores in the second year (R=0.464, p< 0.01). The third-year students' score was quite low on the written examination and slightly low on the CPX/OSCE compared to that of the fourth-year students. The written examination and CPX/OSCE cannot replace each other and should be combined with other methods of evaluation to measure competency. Early OSCE and workplacebased assessment should be useful in the early assessment of clinical skills competency.

본 연구에서는 한국인 성인에서 ant-HCV 양성인 군에서 HCV RNA 유무에 따른 지질, 인슐린저항성 및 대사증후군의 지표 수준의 차이를 알아보고자 하였다. 2004년 1월 1일부터 2010년 12월 31일까지 부산의 일개 대학병원 건강증진센터를 방문하여 검사한 효소면역측정법에서 anti-HCV 양성인 수진자 중 RT-PCR을 시행한 성인 222명을 대상으로 하였다. 이 중 HCV RNA가 양성인 사람이 85명, HCV RNA가 음성인 사람이 115명, HCV RNA의 음전이 확인된 사람이 22명이었다. 허리둘레, 체질량지수, 혈압과 총콜레스테롤, LDL 콜레스테롤, HDL 콜레스테롤, 중성지방, 인슐린저항성의 상관관계를 분석하고, 나이, 성별을 보정한 후 세 군간의 콜레스테롤, 대사적 지표, 인슐린저항성의 차이를 알아보았다. HCV RNA 양성군에서 음성군 및 음전군과 비교하여 허리둘레, 체질량지수, 혈압, 중성지방, HDL 콜레스테롤, 인슐린저항성 등에 통계적으로 유의한 차이는 없었다. HCV RNA 양성군에서 음성군에 비해 총콜레스테롤과 LDL 콜레스테롤이 통계적으로 유의하게 낮았다(186.24±37.63 vs 197.22±37.23 mg/dl (mean±SD), p=0.041, 111.66±34.06 vs 121.38±35.50 mg/dl (mean±SD), p=0.042). 나이, 성별을 보정한 뒤, HCV RNA 양성군과 음성군 간에 고콜레스테롤혈증과 LDL 콜레스테롤혈증의 교차비는 0.51(95% 신뢰구간 0.28-0.94, p=0.03), 0.46(95% 신뢰구간 0.24~0.87, p=0.02)이다. HCV RNA 양성군에서 음성군에 비해 고콜레스테롤혈증, LDL 콜레스테롤혈증의 유병률이 통계학적으로 유의하게 낮았으나, HCV RNA 음전군은 양성군에 비하여 통계학적으로 유의한 차이가 없었다. C형 간염과 대사증후군의 관계를 보다 정확히 규명하기 위해서는 향후 보다 대규모 집단에서 전향적인 코호트 연구가 필요할 것으로 생각된다. Objectives: We compared the difference of lipid, insulin resistance and metabolic markers based on HCV RNA in Korean adults. Methods: This was a cross-sectional study of 222 subjects visited the health promotion center of Pusan national university hospital from 2004 to 2007. Subjects were anti-HCV antibody positive and were performed RT-PCR for HCV RNA. The HCV RNA (+) group were 85 subjects, HCV RNA (-) control group were 115 subjects, and the HCV RNA (-) but past positive group were 22 subjects. We performed anthropometry, anti-HCV, RT-PCR, plasma concentrations of insulin, total cholesterol, LDL-cholesterol, HDL-cholesterol, and triglyceride. Results: BMI, waist circumference, blood pressure, fasting plasma glucose, triglyceride, HDL cholesterol, insulin resistance such as HOMA-IR and QUICKI were not significantly different between HCV RNA positive and negative groups. The serum total cholesterol and LDL cholesterol level were significantly lower in the HCV RNA positive group than in the negative group (186.24±37.63 vs 197.22±37.23 mg/dl, p=0.041, 111.66±34.06 vs 121.38±35.50 mg/dl, p=0.042). After adjusting age and sex, high total cholesterol (≥ 200mg/dl) (adjusted OR=0.51, 95%CI 0.28-0.94, p=0.03) and high LDL cholesterol (≥ 130mg/dl) (adjusted OR=0.46, 95%CI 0.24~0.87, p=0.02) were inversely associated with being HCV RNA positive (p<0.05). Conclusion: The serum total cholesterol and LDL-cholesterol level were significantly lower in HCV RNA (+) group than in HCV RNA (-) group, but not in HCV RNA (-) but past positive group. Prospective cohort studies are needed to clarify the relationship between HCV RNA and metabolic markers.
