This paper reviews current trends in clinical research. Clinical research can be defined as the study of humans or groups of humans. In the field of clinical research, Korea ranks 7th in the world. To improve healthcare policy and clinical strategy for diagnosis and treatment, scientific evidence based on clinical research is needed. To increase the transparency of clinical research, all clinical research should be registered before starting. To register clinical research, the World Health Organization (WHO) established International Clinical Trials Registry Platform (ICTRP), and the Korea Centers for Disease Control and Prevention established Clinical Research Information Service (CRIS). CRIS is approved by the WHO as a primary registry and meets the criteria of ICTRP. The United Kingdom and the United States established National Institute for Health Research and Patient- Centered Outcomes Research Institute respectively to fund clinical research publicly. The United States ‘ClinicalTrials. gov’ is the most well-known web clinical research registry service. Industry led research has therefore, governments of advanced countries have increased public research funds.

Objectives : To examine various dimensions of consumer ratings of health care service with factor analysis and to find which factors influence the overall quality of health care service. Methods : A cross-sectional study was conducted on outpatients of a general hospital located in Sungnam City. A self-administered questionnaire was used to assess the consumer's ratings of health care service received. The response rate was 92.8% with a total of 537 persons completing the questionnaire. Factor analysis was performed on 34 items evaluating the quality of health care service. Items were grouped into 5 dimensions as a result of factor analysis and the reliability and validity of influence on patient service assessment were evaluated for each dimension. Results : The 5 dimensions were as follows, 1) physician services, 2) non-physician services, 3) process 4) facilities, and 5) cleanliness A positive correlation with the quality of health care service was found for the dimensions of non-physician services and process, while no significant correlation was found for the dimensions of physician services, facilities, and cleanliness. Conclusions : The result of this study may provide basic information for the development of future self-administered questionnaires of consumer ratings and for the evaluation of quality improvement activities in hospital outpatient settings.

Objectives : To identify the factors related to awareness, treatment, and control of hypertension in a Gwacheen population. Methods : This study surveyed 1,176 Gwacheon residents older than 40 years, and measured blood pressure using a standardized guideline in 1999. The study subjects were 473 adults (175 males, 295 females) with hypertension defined as a systolic blood pressure $\geq$140 mmHg, diastolic blood pressure $\geq$90 mmHg or reported treatment with antihypertensive medication. Information on awareness, treatment, and control of hypertension, and sociodemographic and health-related factors .was collected through person-to-person interviews with a structured questionnaire. Results : Overall, 252 (53.3%) of hypertensive subjects were aware of their condition, of whom as many as 193 (76.6%) were being treated, and 81 (42.0%) had their blood pressure controlled at the recommended level (<140/90 mmHg). However, of the 473 subjects found to have hypertension, only 40.8% were being treated, and 17.1% were under control. There were no significant differences in the proportions of awareness, treatment, and control of hypertension. In multiple logistic regression models, awareness of hypertension was positively associated with age and family history of hypertension in females. Control of hypertension was also positively associated with haying a partner and marital status in females.. Conclusion : These findings demonstrate that much greater efforts on improving awareness, treatment, and control of hypertension are needed, even in urban community settings, considering related factors such as a9e, family history, and marital status. However, these factors should be further investigated for their causal relationship.

Objectives : We examined the effect of sociodemographic factors, cancer, and psychiatric disorders on suicide by gender and age-specific patterns in South Korea. Methods : The study is a case-control study. Claim data was obtained from the national health insurance database and national death registration database. The number of people who committed suicide was 11,523, which was matched with a control group consisting of ten times as many people at 115,230 selected from the national health insurance and medical aids beneficiaries. The medical utilization of the case group was one year before death and that of the control group was from July 1,2003 to June 30, 2004. Four variables-address, economic status, presence of a psychiatric disease, and cancer-were used in multiple logistic regression analyses. Results : Living in cities or in rural areas showed a greater risk for suicide than living in a metropolitan city. Low economic status, the presence of a psychiatric disorder, and cancer were also statistically meaningful risk factors for suicide. The three major psychiatric diseases, schizophrenia, alcohol abuse, and bipolar disorder, were meaningful in all age groups, but the scale of the odds ratio differed by the age group. Only the psychiatric disorder variable was meaningful in the adolescent group, whereas a psychiatric disorder and economic status were meaningful for the young adult group, and all variables were meaningful for the middle-aged group. A psychiatric disorder and cancer were meaningful in the elderly group, economic status was meaningful for male subjects, and address was meaningful for female subjects. Conclusions : Factors such as living in city or rural areas, low economic status, the presence of a psychiatric disorder, and cancer were statistically meaningful risk factors in suicide. These factors also differed by age group. Therefore, policymakers should establish policies for suicide prevention that are relevant for each age group.

This study was designed to suggest a learning organization in a medical center by examining the factors to influence effectiveness of the learning organization. We collected the data of 586 persons who participated once or more times in the learning organization managed from 2000 to 2002 by Y Medical Center located in Seoul, and included the data of 285 persons in the final analysis. The results of the study are summarized as follows. First, as the results of examining the regression coefficients to predict the effectiveness of and satisfaction with the learning organization through the learning level, learning method and learning organization constructing level as the general variables, the important influential factors were shown as follows: 1)knowledge creation, knowledge storing, private learning, organizational learning, and learning organization construction of occupational and human levels as the factors to predict the working competency: 2) learning organization construction of the human level as the factors to assume the duty satisfaction; 3) gender, working years, private learning, team learning and organizational construction level for the prediction of the organizational commitment; and 4) medical technical service, knowledge creation, organization learning, and constructing level of the environmental and human levels for the assumption of the satisfaction with experience in the learning organization. Based on the study results of the effects in managing the learning organization, we can conclude the followings. First, the members who are in various working positions and occupations need to continuously participate in the learning organization. Second, to raise the organizational outcome from the management of the learning organization, it is necessary to establish systematic concepts in the constituents of the organizational effectiveness such as working competency improvement, duty satisfaction and organizational commitment, and the experience satisfaction of the learning organization. Finally, the future of the organization depends on the learning competencies of the organization members. To continuously exist and develop the organization, the private learning of the organizational members should be constantly spread and shared over the organizational level, and the usual innovations such as repetitive and habitual organizational learning should be generally tried out throughout the whole field of the management.

Objectives: Isocyanate-induced asthma is the most prevalent occupational asthma in Korea. The main purpose of this study was to estimate the etiologic fraction of isocyanate-related asthma in isocyanate- exposed (EFe) workers and to measure the magnitude of preventable occupational asthma. Methods: Asthma admissions from 2000 to 2005 were analyzed in a cohort containing 10,861 iso-cyanate-exposed workers and 324,618 isocyanate non-exposed workers who underwent the specialized health examination from January, 2000 to December, 2004. The cohorts of Isocyanate and noise-exposed workers were established using the same data base of Korea Occupational Safety and Health Agency (KOSHA). Asthma admissions were investigated by matching the National Health Insurance Claim Data (NHICD). The standardized rate ratio (SRR) of admission was estimated by Poisson regression method to allow unbiased comparisons across exposure and other variables such as age and sex. The etiologic fraction for the isocyanate-exposed (EFe) workers was calculated using this formula (Efe=SRR-1/SRR). Results: Twenty-eight asthma admissions among the isocyanate-exposed workers and 321 non-exposed workers were observed during 2000∼2005. The crude admission rate was 57.2 per 100,000 person-years for the isocyanate-exposed workers and 25.0 for the noise-exposed workers, Compared to the noise-exposed workers, the isocyante-exposed workers had significantly higher asthma admission (SRR=2.80 95%CI=1.89∼4.14). The etiologic fraction for the isocyanate-exposed (EFe) workers was 64%. Conclusions: This study was limited by the restriction to admission cases and the short follow-up periods. Any difference of admission accessibility between the isocyanate-exposed and non-exposed workers will lead to either over- or under-estimation of the biased etiologic fraction for the isocyanate-exposed workers. The etiologic fraction for the isocyanate-exposed workers was 64% indicated that 64% of the asthma cases occurred in the isocyanate-exposed workers are preventable through occupational health management. 목적: 이 연구의 목적은 우리나라에서 가장 중요한 직업성천식원인물질인 이소시아네이트에 노출되는 근로자를 대상으로 이들 근로자의 천식 중 이소시아네이트의 원인 점유율을 산출하는 것이다. 방법: 2000년부터 2004년까지 이소시아네이트 및 소음 특수건강진단을 받은 근로자의 전산자료를 한국산업안전공단으로부터 수집하였다(한국산업안전공단에 2000년부터 특수건강진단을 받은 근로자의 자료가 전산화되어 있음) 이들 근로자에 대하여 2000년부터 2005년까지 6년간 천식으로 입원한 근로자의 자료를 건강보험심사평가원으로부터 조회하였다. 이소시아네이트와 소음 특수건강진단 수진자에 대하여 관찰인년을 계산하고 조입원률을 계산하였다. 소음 특수건강진단 근로자를 비교집단으로 하여 포아송 회귀분석 로그- 선형 상대 위험률 모형을 적용하여 이소시아네이트 특수건강진단 수전자의 입원의 표준화비율비를 산출하고 이를 이용하여 이소시아네이트 노출 근로자의 천식 중 이소시아네이트의 원인점유율을 산출하였다. 결과: 이소시아네이트 노출 근로자의 조입원률은 10만 관찰인년당 57.2명(남성 50.4명,여성 113.0명),소음은 25.0명(남성 22.7명,여성 31.6명)으로 이소시아네이트 노출 근로자의 천식 조입원률이 2.3배 높았고,여성의 경우 3.6배 높았다. 소음 노출 근로자에 대한 이소시아네이트 노출 근로자의 천식의 표준화비율비는 2.80(95% 신뢰구간 1. 89∼4.14)으로 소음 노출근로자에 비하여 이소시아네이트 노출 근로자의 입원이 180% 많았다. 이소시아네이트의 원인점유율은 64%(95% 신뢰구간 47∼76%)로 이소시아네트 노출 근로자에서 입원한 천식의 64%는 이소시아네이트에 의한 것으로 분석되었다. 결론: 이 연구에서 이용한 자료는 천식 입원자료로 유병자료라는 제한점이 있다. 그러나 이 연구는 국내에서 처음으로 특정 물질 노출군(특히 우리나라 직업성천식의 가장 흔한 천식 유발물질인 이소시아네이트 노출군)을 대상으로 천식 중 직업(노출)의 원인점유율을 측정한 것은 의의가 있다. 이 연구에서 이소시아네이트 노출군의 천식 중 노출 회피 등을 통하여 예방 가능한 부분이 64%이고, MDI 노출군의 천식의 상대위험도와 원인점유율이 TDI 보다 높다는 사실은 이소시아네이트 노출 근로자 산업보건관리에 매우 중요한 의미가 있다고 판단된다. 향후 이 연구결과를 이소시아네이트 노출 근로자의 직업성천식 예방 및 산재 보상정책을 수립하는데 기초자료로 활용할 필요가 있다고 판단된다.
