OBJECTIVES: This paper presents the information on the incidence of cancer from the population-based cancer resistry in Kangwha County. Material and METHODS: This investigation is based on Kangwha cancer registry. The data included cases of cancer diagnosed from 1986 through 1992. The diagnosis of cancer was confirmed by a team of physicians and nurses with the medical records kept in the clinics and hospitals based on the diagnostic criteria recommended by WHO. Home visitings were also made to cancer patients confirmed in every 6 months for the follow up and for the collection of relevant information directly from the patients. RESULTS: A total of 992 cancer cases were registered during 1986 - 1992. The age-adjusted cancer incidence rate of all site is 201.7 in men and 110.7 in women. The most common cancer is the stomach cancer in both sexes. The age-adjusted incidence rate of the stomach cancer is 65.9 in men and 25.0 in women per 100,000 population. The lung cancer(33.8) and liver cancer(27.7) are next common cancers in men. The cervical cancer(21.8) and lung cancer(8.4) are next in women. CONCLUSION: The most common cancer is the stomach cancer in both sexes. The annual age-adjusted incidence rate of the stomach cancer is 65.9 in men and 25.0 in women per 100,000 population.

2.Potential for Integrated Medical School and Oriental Medical School Curriculum.
Korean Journal of Medical Education 1998;10(2):337-349
This study aims to suggest potential steps required for the integration of medical and oriental medical school by comparing the curriculum and its content between the two. The analysis was based on the specific behavioral objectives(SBOS) of the Korean Medical Association and Oriental Medical School Association. We used the school's catalog as well to get information on courses that are offered, hours, and credits. Major findings were as follows. 1. Clinical courses that are taught in oriental medical schools cover about 75% of the courses offered in medical schools on the basis of SBOS. This suggests that western medical knowledge is required for training oriental medical doctors in Korea. 2. If the SBOS of clinical medicine is taught for another 1 year at the oriental medical school, it will cover the entire content of the medical school. Also if 1.5 years of oriental medicine content is taught at medical school, it will include the whole SBOS offered in orienta medical school. Including a 1 year of clinical practicum, the extra years of required education would be 2 years for oriental medical students and 2.5 years for the medical students. Planning for an integrated for medical and oriental medicine requires close cooperation between all parties in practice and academics. A newly developed level of medicine will emerge from this if the plan takes into account the establishment of medical and oriental medical graduate schools and KMA's movement to reduce the number of SBOS to be taught in medical schools.

OBJECTIVE: To examine the association between age at menopause and mortality in a population-based sample of women in Kangwha, Korea. METHODS: From the Kangwha Cohort, followed-up from 1985 to 1999, the data of the over 55 year old female group(n=3,596) was used in this study to examine the association between age at menopause and mortality. We calculated the all causes mortality risk ratio and the cancer mortality risk ratio by age at menopause grouping using the Cox Proportional Hazards Model with adjustments for age, BMI, smoking, education, chronic disease, self-rated health status, alcohol consumption and age at first birth. RESULT AND CONCLUSION: Compared to women who had menopause at 45-49 years, the all causes mortality risk ratio was 1.24 for women with menopause at less than 40 years(95% CI=1.01-1.53) and 1.05 for women with menopause at over 50 years(95% CI=0.92-1.20). Also, compared to women who had menopause at 45-49 years, the cancer mortality risk ratio was 1.53 for women with menopause at less than 40 years(95% CI=0.78-2.98) and 1.17 for women with menopause at over 50 years(95% CI=0.77-1.80).

OBJECTIVES: This study was to investigate the mental health status and quality of life of Korean-Chinese workers, who are residing illegally in Korea. METHODS: Total 147 illegal status Korean-Chinese workers completed to the questionnaire for demographic data, Korean version of Symptom Check List-90-Revision (SCL-90-R) and Korean version of World Health Organization Quality of Life Scale (WHOQOL-BREF). RESULTS: The results of this study showed that general mental health was relatively poor and the quality of life was relatively poorer among Korean-Chinese. Mental health and quality of life were worse among those who accompanied spouses, had no religion, had less income, and those who experienced unjust treatments such as delayed payment, violence and industrial accidents. There were significant correlations between scores of all categories of SCL-90-R and scores of domains of physical health, social relationship and environment in WHOQOL-BREF. CONCLUSION: These results suggest that Korean-Chinese laborers in illegal status in Korea need improved treatment neleved from delayed payment, social violence and industrial accidents and with extended medical service and better residential environment.

Korean Journal of Medical Education 1999;11(2):297-312
The purpose of this study is to discuss the evaluation system of teaching ability of medical college faculty members. Reviewing of books and journals ha s been carried out by the authors so that the problems and methods of faculty evaluation may be discussed. The practical Korean data on the faculty evaluation system were collected by the department of faculty affairs of each college in March 1998. Faculty evaluation can be divided into two dimensions-dynamic and static dimensions. The methods vary according to evaluators, such as self evaluation, student evaluation, peer evaluation and administrator evaluation. On the bases of the object or the time of evaluation, it can be divided into formative or summative evaluation. According to the methold of data collection, it also can be divided into literature evaluation, observation evaluation and site visiting evaluation as well. The authorities of medical colleges used to give much more weight on the research activities rather than on teaching abilities. This kind of idea has been pushed faculty members to stress on research activities not on teaching abilities. Some inportant problems detected in this study are the narrow evaluation scope of aculty teaching activities, the not well established rationale of the evaluation, the underdevelopment of evaluation items, and the rigidity of the related authority. The introduction of a faculty track system is recommended as a desirable arrangement to develop the evaluation system in Korea.

6.Low Systolic Blood Pressure and Mortality From All Causes and Vascular Diseases Among Older Middle-aged Men: Korean Veterans Health Study.
Journal of Preventive Medicine and Public Health 2015;48(2):105-110
OBJECTIVES: Recently, low systolic blood pressure (SBP) was found to be associated with an increased risk of death from vascular diseases in a rural elderly population in Korea. However, evidence on the association between low SBP and vascular diseases is scarce. The aim of this study was to prospectively examine the association between low SBP and mortality from all causes and vascular diseases in older middle-aged Korean men. METHODS: From 2004 to 2010, 94 085 Korean Vietnam War veterans were followed-up for deaths. The adjusted hazard ratios (aHR) were calculated using the Cox proportional hazard model. A stratified analysis was conducted by age at enrollment. SBP was self-reported by a postal survey in 2004. RESULTS: Among the participants aged 60 and older, the lowest SBP (<90 mmHg) category had an elevated aHR for mortality from all causes (aHR, 1.9; 95% confidence interval [CI], 1.2 to 3.1) and vascular diseases (International Classification of Disease, 10th revision, I00-I99; aHR, 3.2; 95% CI, 1.2 to 8.4) compared to those with an SBP of 100 to 119 mmHg. Those with an SBP below 80 mmHg (aHR, 4.5; 95% CI, 1.1 to 18.8) and those with an SBP of 80 to 89 mmHg (aHR, 3.1; 95% CI, 0.9 to 10.2) also had an increased risk of vascular mortality, compared to those with an SBP of 90 to 119 mmHg. This association was sustained when excluding the first two years of follow-up or preexisting vascular diseases. In men younger than 60 years, the association of low SBP was weaker than that in those aged 60 years or older. CONCLUSIONS: Our findings suggest that low SBP (<90 mmHg) may increase vascular mortality in Korean men aged 60 years or older.

It is not yet clear whether Glutathione S-transferase M1 (GSTM1) polymorphisms affect the risk of breast cancer. The aim of this study is to provide a comprehensive meta-analysis of all the available, published case-control studies on the extent of the possible association between GSTM1 polymorphisms and susceptibility to breast cancer. Twenty case-control studies on GSTM1 and breast cancer were identified using both PUBMED and a manual search. Meta-analysis was conducted by the Peto method. Subgroup analyses were undertaken, in order to explore the relationship between effect sizes and the study characteristics. The overall odds ratio (OR) was found to be 1.06 (95% CI, 0.99-1.14). The OR for post-menopausal women with GSTM1 deficiency was determined to be 1.19 (95% CI, 1.05-1.34). In populations with a low frequency of GSTM1 deficiency, a greater increase was observed (OR, 1.20; 95% CI, 1.08-1.34). Furthermore, the highest associations were found in post-menopausal women with a low frequency of GSTM1 deficiency (OR, 1.44; 95% CI, 1.20-1.73). The fact that GSTM1 deficiency is not rare in the general population implies that the attributable risk for breast cancer could be sizable. Further studies focusing on the structure of haplotype blocks of GSTM1 are required in order to find a specific haplotype with a predisposing breast cancer susceptibility allele.

The relationship between smoking and total mortality was examined in a community residents population sample of 2,848 men and 3,543 women aged 55 years or over in Kangwha County, Korea during 1985-1991. A total of 1,436 deaths occurred during a 6-year follow-up among the 1.3 fold-higher in current smokers than in non-smokers among men. The relative risk of total mortality was highest for the 55-59 year old age group both in ex-smokers and in current smokers. PAR for total mortality attributed by smoking were estimated to be 26% for ex-smokers and 25% for current smokers in men. The biggest RR (2.1) and PAR (49%) were observed among those who smoked less than 19 cigarettes per day compared to non-smokers in males. Smokers who began to smoke at age 18 or before showed RR 1.8, and PAR 38% in men. Smoking was the most important variable related with total mortality second only to hypertensiveness not including preventable ones among men in multivariate analyses. Men who began to smoke at nineteen years of age or before had RR 1.5 for total cancer mortality. Women showed the similar picture as males in risk factors composition and in relative risks, with a low association strength, however.

OBJECTIVES: To propose a feasible, valid and appropriate study designs and epidemiologic methods for evaluating the adverse health effects of Agent Orange-chemical defoliants used in Vietnam- in Korea. METHODS: A literature study was performed on Agent Orange, herbicides, pesticides and dioxins. The study subjects, study design, exposure assessment and health outcomes assessment were examined in each study. The potential data sources for the study subjects, study design, exposure assessment and health outcomes assessment in Korea were investigated. RESULTS AND CONCLUSION: In earlier Korean studies, research subjects for studying the effects of Agent Orange were identified from the patients or persons who claimed to have Agent Orange-related diseases due to the difficulties in identifying the entire population of Vietnam veterans in Korea. In this study, an attempt was made to identify the total number of Vietnam veterans in Korea. As a result, the addresses of 20,000 Vietnam veterans were obtained. It is proposed that a retrospective cohort design on a sample of the total number of Vietnam veterans is a feasible and appropriate study design. Self report questionnaires and military records were proposed to assess the exposure level. It is believed that measuring the plasma or tissue TCDD should be used only for a validation study assessing the level of exposure. For the health outcomes assessment, it is possible to obtain the mortality, cancer frequency, physical examination, screening and medical insurance record data.

OBJECTIVE: To analyze the factors affecting the participation rate in the health screening program of medical insurance. METHOD: We investigated the factors associated with the participation rate in the health screening program in Korea. Data were collected at the aggregate level from 145 employee health insurance societies and 227 self-employed health insurance societies from 1995 to 1997. Data were also collected at the individual level from four health insurance societies. This study hypothesized that the participation rate of the health screening program was related to 1) the characteristics of its members and the size of the health insurance society; 2) the specifications of the health screening program; 3) the venue of the health screening institution and the interests of individuals in the health screening program; and 4) the activities of the health insurance society. We used bivariate and multiple regression models to examine the factors on the participation rate of the health screening program. RESULTS: First, in the case of dependents of on employee health insurance society, the ratio of dependents 40 years old and over, the average monthly contribution per household, the interest and satisfaction level of individuals in health screening, and the level of refunds for over-payment were all associated with the participation rate in the health screening program, accounting for 54.4% of the participation rate. Second, in case of those insured by the self-employed health insurance society, the interest and satisfaction level of individuals in health screening, the level of refunds for over-payment, and the performance level of on-the-spot health screening were statistically significant, accounting for 40.1% of the participation rate. CONCLUSION: The factors concerning the participation rate in the health screening program of medical insurance, in both a health insurance society and for individuals, were closely related to the age and gender of individuals and household contributions.
