Objectives: This 3-year longitudinal study was conducted to evaluate the influence of self-rating health perception on health care utilization and all cause-death risk. Methods: The hypothesis was tested using a community-based samples, among which subjects 3,414 were interviewed in 1995, Self-rating health perception was assessed by single-item question. Three components of health care utilization amount(number of visits, number of medications, yearly health care expenses) per year were measured using medical insurance data during 3-year follow-up period among subjects in district health care insurance. There were 123 deaths from all causes among 3,085 subjects interviewed. Results: The results showed that those who had poor health perception revealed more increases in the amount of health care utilization than good health perception group (p<0.05). After adjusting for age and sex, the poor health perception group had higher death risk over 3 years than good health perception group(hazard ratio=1.88). but, after adjusting health care utility, supplementary, was not significant. Conclusion: These results suggest that self-rating health perception was associated with difference in health care utilization and all cause-death risk. 1995년 1월과 7월에 전라남도 일부 농촌지역에 거주하는 20세 이상의 주민 3,085명을 대상으로 자가건강인지도를 측정하였다. 이후 3년간의 지역의료보험 지불자료에서 나타난 의료이용도 및 해당 지역 행정관청의 사망신고 자료를 이용하여 사망여부를 파악하여, 이들 변수들과 자가건강인지도와의 관련성을 조사해본 결과, 다음과 같은 결과를 얻었다. 1) 지역의료보험 대상자 1,090명에서 자가건강인지도에 대한 설문을 실시하기 이전인 1994년의 의료이용량에 비해 이후 3년간의 의료이용량이 자가건강인지도 불량군에서 더 많았으며, 수진일과 투약일은 더 크게 증가하였다. 2) 조사대상자 3,085명중 3년간의 사망자는 123명으로 연령과 성별을 보정한 생존분석 결과, 자가건강인지도 불량군이 양호군에 비해 더 높은 사망위험도를 나타냈다. 94년 지역의료보험에 가입되었던 1,376명중 사망자는 72명, 연령과 성별, 그리고 94년도 의료이용량을 보정 한 생존분석 결과 유의한 차이는 보이지 않았다. 이상의 결과를 요약해 볼 때, 비교적 단기간의 비교를 통해서도 의료이용도와 사망은 자가건강인지도에 따라 차이가 발생함을 알 수 있다. 특히 기존에 같은 정도의 의료이용을 하는 사람 중에서도 자신을 건강하지 않게 생각하는 사람이 향후 의료이용량이 더 크게 증가할 것으로 예측되었다. 따라서 자가건강인지도의 측정은 향후 개인 및 지역사회집단의 의료이용도와 사망 등 건강상의 문제를 예측하는데 유용한 도구로 사용할 수 있을 것으로 생각된다.

This study aims to understand if the size of a general hospital affects its profitability and, if so, what factors affect this. This study examined public(medical corporation) general hospitals. It was differentiated from previous studies by dividing these hospitals into large, medium, and small-sized hospitals based on the number of beds and levels. According to the study, the variable of personnel expenses, material costs, and maintenance costs was significant for all hospitals, whichever variable was used for profitability, whereas the variable of interest costs was significant for the profitability of medium and small-sized hospitals. These results suggest the following implications. Future studies on the profitability of general hospitals need to consider the characteristics by bed-numbers. The continuity of a study can be improved through the use of officially released financial materials. In addition, it is considered important for hospitals of any size to manage personnel expenses, maintenance costs, and material costs as against medical service profit to improve profitability. The management of interest costs is also important, especially for medium and small-sized general hospitals.

This study was carried out to investigate the residue level of fluoroquinolones in hen`s general eggs and specific eggs by microbiological assay method and high performance liquid chromatography (HPLC) method. HPLC separation was carried out by reversed phase chromatography on a Symmetry C18 (250 × 4.6 ㎜, 5 ㎛ particle size) with a phase composed of distilled water (containing 0.4% triethylamine and phosphoric acid) : Methanol (780 : 220, v/v), pumped isocratically at a flow rate of 1.0 ㎖/min. A fluorescence detector was utilized with an excitation wavelength of 278 ㎚ and an emission wavelength of 456 ㎚. The calibration curves were linear (γ2≥0.999) over a concentration range of 0.025~0.4 ㎍/㎖. Average recoveries of the five fluoroquinolones in whole eggs at fortified levels of 0.05~0.2 ㎍/g were ranged mean 78.1~91.7% and low coefficient of variation was less than 10% for all analysed samples. The limits of detection and limits of quantification for whole eggs were 1.2~6.0 ng/g and 2.3~9.1 ng/g, respectively. Only one hen`s general eggfrom chicken farm in Incheon was detected with the residual fluoroquinolones (Microbiological assay method ; 1 of 47 general eggs) ; the range of residual concentration enrofloxacin was 0.12 ppm. Those in food stores were detected with the residual fluoroquinolones (Microbiological assay method ; 4 of 88 general eggs) ; the ranges of residual concentration enrofloxacin were 0.15~2.2 ppm, ciprofloxacin 0.01~0.06 ppm, and hen`s specific eggs (40) in food stores were not detected. For the microbiological assay method of fluoroquinolones in hen`s eggs, as the results of comparative analysis, the disc diffusion method with E coli may be a little highly detected for the residual fluoroquinolones.

Objectives : To evaluate the annual visit days, the annual prescription days and the medical costs of hypertensive patients. Methods : The medical insurance records of 40,267 incident patients with the diagnostic code of hypertension from September 1998 through August 1999 in Daegu city were reviewed. Results : The proportion of the most proper medical care pattern group (Group VIII) who visited for 6-15 days with 240 prescription days or more a year was only 6.2%. The proper care group (Group IX) who visited for more than 16 days with 240 prescription days or more a year was 9.3%. The overall proper care group (Group VIII+IX) was therefore 15.5%. The proportion of the insufficient care group (Group I, IV) in both the number of visiting days and prescription days was 57.4%. The mean prescription day of the most proper group (Group VIII) was 29 days; the mean annual medical expenses,453,587won; the mean annual amount paid by patients, 218,013won; and mean medical expenses per prescription day, 1,483won. The proportion of the overall proper care group (Group VIII+IX) was significantly higher in adults aged 50-59, those who were enrolled in industrial workers health insurance as well as government employees and private school teachers health insurance, and those who made a higher contribution per month (p<0.01). According to the type of medical facilities, the proportion of the most proper medical care pattern group was highest in the general hospitals (9.3%) but the overall proper care group was higher in the public health centers (22.1%) and private clinics (17.1%). Conclusions : The management system of hypertension should be reinforced urgently. Therefore, it is necessary to develop guidelines including the number of visiting days per year and prescription days per visit day, and make the system provide medical facilities to more properly care for hypertensive patients.

Materials and Methods : The control group consist of 30 patients with class I occlusion. The experimental group consist of 44 patients with class III malocclusion. Three-dimensional computed tomography was used to evaluate the position of the mandibular foramina. Results : The distance between mandibular plane and mandibular foramen, class I was 25.385 mm, class III was 23.628 mm. About the distance between occlusal plane and mandibular foramen, class I was 1.478 mm, class III was 5.144 mm. The distance between posterior border plan of mandibular ramus and mandibular foramen had not statistically significant. About the distance between sagittal plane of mandible and mandibular foramen did not also showed statistically significant. Conclusion : The result of this study could help the clinicians to apprehend more accurate anatomical locations of the foramina on the mandible with various facial skeletal types. thereby to perform more accurate block anesthesia of the mandibular nerve and osteotomy with minimal nerve damage. In addition, this study could provide fundamental data for any related researches about the location of the mandibular foramina for other purposes.

Objectives : This study was aimed at investigating the medical service utilization pattern of patients who use public medical aid compared to those who have health insurance. Methods : We selected every patient between the age of 18 and 69 who used public medical aid from January 1, 1999, to December 31, 2001, in Gwangju metropolitan city, South Korea. For comparison, a list of patients with health insurance was gathered for same period. Then the medical records of those who had been hospitalized for acute appendicitis were selected among both groups. Of those records, we compared the number of cases of ruptured appendicitis to cases of whole acute appendicitis in both groups. Regarding coding for ruptured appendicitis, International Classification of Diseases - 10 (ICD-10) was used. Multiple logistic regression was used as a statistical tool to determine the effectiveness of risk factors. Results : Even after adjusting for risk factors, such as age and sex, the proportion of perforation of acute appendicitis among public medical aid patients was found to be significantly higher than among insured patients. Conclusions : This comparative study on ruptured appendicitis among public medical aid patients and insured patients, indicates that the proportion of perforation of acute appendicitis could be an index showing that these types of patients utilize medical services differently than insured patients. We know that when abdominal pain is not properly treated at the outset, it easily develops into ruptured appendicitis complicated with peritonitis. Considering this data analysis, we guess the public medical aid system to have significant problem with medical accessibility. So additional and systematic research on the pattern of utilization of medical services of public medical aid patients is needed.

병원에 내원하거나 심폐소생술 교육에 참가한 사람들을 대상으로 했던 대부분의 기존 연구와는 달리 본 연구에서는 2006년 8월 실시된 ‘도서산간지역의 응급의료현황분석 및 지원방안모색’을 통해 체계적으로 수집 조사된 자료를 이용하여 사회 경제적 특성, 건강 및 의료적 특성과 심폐소생술 교육 희망을 비교 고찰하였다. 도서 산간 지역에서 심폐소생술 교육을 희망하는 집단과 그렇지 않은 집단 간에 성별, 연령, 학력, 생활수준, 심폐소생술 교육 경험, 건강 상태 인지도 등에서 유의한 차이가 나타났다. 또한 성별, 연령, 생활수준, 그리고 심폐소생술 교육 경험 등은 심폐소생술 교육 희망에 유의한 영향 요인으로 나타났다. 반면에 혼인여부, 거주 지역, 본인이나 가족의 심혈관계 및 호흡기계 증상 유무, 사고 경험이나 응급실 이용 여부는 두 집단에 유의한 차이가 없었으며, 심폐소생술 교육 희망에 유의한 영향 요인도 되지 못하였다. 본 연구에서 일부 도서 산간 지역 주민의 심폐소생술 교육 희망 여부와 관련 요인을 분석하고 있으나 다른 도서 산간 지역 또는 도시지역과의 쳬계적인 비교 분석에는 미치지 못하는 한계가 있다. 그러나 도서 산간 지역의 심폐소생술 교육 희망 여부를 중심으로 특성과 함께 영향 요인을 분석하고 있다. 향후 도서산간 지역의 일반인을 대상으로 하는 심폐소생술 교육에서 교육 희망자의 사전적인 특성 분석을 통해 수요자 중심의 교육 확산을 도모할 수 있는 계기가 되며, 정책적 목표에 부합하는 집중 교육 대상자의 효과적인 교육 참여를 유도할 수 있을 것으로 기대된다. 아울러 사후적으로 실제 심폐소생술 교육에 참가한 사람들의 특성이나 영향 요인에 대한 지속적인 연구가 필요하다. Objectives: The purpose of this study is to describe and analyze the characteristics of which laypersons want the cardiopulmonary resuscitation(CPR) education. Methods: Based on a health survey(n=913) of 5 remote places in Korea, tests of the differences between the group that wants the CPR education(n=416) and the group that doesn"t(n=497), and a logistic regression analysis of two groups was performed on socio-economic status and health-medical conditions. Results: Even the participation rate of the CPR education in Korea is only 5.8%, which is extremely lower than other developed countries, there are statistically significant differences between the group that wants the CPR and the group that doesn"t on gender(p=0.001), age(p=0.000), education level(p=0.000), economic status(p=0.007), and CPR education taken(p=0.000), and health status(p=0.042). Furthermore, age(OR=1.599, p=0.002), age(OR=0.964, p=0.000), economic status(OR=0.804, p=0.028), and CPR education taken(OR=2.072, p=0.026) are statistically significant factors on the willingness to receive the CPR education. Conclusions: This study indicates that there is considerable variation in socio-economic status and health-medical conditions associated with the willingness to receive the CPR education. In remote places. certain subgroups of laypersons such as high-risk patients and family members need targeted outreach programs in CPR education.

Objectives : To evaluate the accuracy of the registered cause of death in a county and its related factors. Methods : The data used in this study was based on 504 cases, in a county of Chonnam province, registered between January and December 1998. Study subjects consisted of 388 of the 504 cases, and their causes of death were established by an interview survey of the next of kin or neighbor and medical record surveys. We compared the registered cause of death with the confirmed cause of death, determined by surveys and medical records, and evaluated the factors associated with the accuracy of the registered cause of death. Results : 62.6% of the deaths were concordant with 19 Chapters classification of cause of death. external causes of mortality, endocrine, nutritional and metabolic diseases, neoplasms and diseases of the circulatory system showed the good agreement between the registered cause of death and the confirmed cause of death. The factors relating to the accuracy of the registered cause of death were the doctors' diagnosis for the cause of death (adjusted Odds Ratio: 2.67, 95% Confidence Interval: 1.21-5.89) and the grade of the public officials in charge of the death registry (adjusted Odds Ratio: 0.30, 95% CI=0.12-0.78). Conclusions : The accuracy of the registered cause of death was not high. It could be improved by using the doctors' diagnosis for death and improving the job specification for public officials who deal with death registration. 전라남도의 일개 군에서 1998년 1월 1일부터 1998년 12월 31일까지 사망으로 신고된 건수는 총 504건이었으며, 이중 설문조사와 의무기록조사로 확인사인의 추정이 가능했던 388건을 연구대상으로 하였다. 확인사인을 신고사인과 비교하고 사망자와 사망관련 변수, 신고자의 특성 그리고 사망신고담당 공무원의 특성에 따른 양자간의 일치율을 통해 신고사인의 정확성과 관련된 인자를 파악하였다. 신고사인과 확인사인의 전체적 일치율은 19대 분류상 62.6%을 보였다. 19대 분류에 의한 사인별 일치율을 보면 손상, 중독 및 사망의 외인이 가장 높았고, 그 다음으로는 내분비, 영양 및 대사질환, 신생물, 순환기계질환 순이었다. 반면에 낮은 일치율을 보인 질환은 피부 및 피하조직의 질환, 근골격계 질환, 정신 및 행동장애 이었다. 사망자 및 사망관련변수에 따른 확인사인과 신고사인의 일치율은 사망자가 남자일 때, 사망 연령이 50대와 60대일 때, 그리고 사망원인 진단자가 의사일 때 높았다. 신고자의 특성별로는 신고자의 연령이 증가함에 따라 일치율이 감소하였으며, 신고자의 교육 정도와 직업과도 유의한 관련성이 있었다. 또한 사망신고 담당 공무원의 특성에 따라서는 공무원의 직급이 6급인 경우 7급 이상인 경우에 비해 일치율이 높았다. 확인사인과 신고사인의 일치여부를 종속변수로 하여 단변량분석을 실시한 후 통계적으로 의미 있는 변수에 대한 로지스틱 회귀분석의 결과를 보면, 사망원인 진단자가 의사인 경우 비차비 2.67(95% 신뢰구간: 1.21-5.89)로 높았으며, 사망신고담당 공무원의 직급이 7급 이상인 경우 비차비 0.30(95%신뢰구간: 0.12-0.78)로 낮았다. 사망신고자료에 기재된 신고사인의 정확성과 관련된 요인에 대한 결과를 종합하여 볼 때 무엇보다 중요한 일은 사망을 의사로 하여금 진단하게 하는 일이다. 또한 사망신고담당 공무원의 업무를 명확히 해야 하며 이들을 대상으로 하는 정기적이며 강화된 교육도 강조되어야 할 것이다.
