The hematologic effect by low-concentration and repeated exposure to mixed organic solvent remains obscure. This study was performed to evaluate the hematologic effect by mixed organic solvent exposure, especially on the type of anemia by mean corpuscular volume(MCV) and red blood cell distribution width(RDW). The subject were 64 organic solvent workers(male 4, female 60) and 78 general workers(male 18, female 60) who showed anemic tendency in worker's health examination which carried out by Pusan Paik Hospital from January to December, 1988. The author gained some hematologic findings(hemoglobin, hematocrit, RBC, WBC, MCV, MCHC, platelet count, ESR, RDW) from auto-analysis method by coulter counter S plus IV, and compared the type of anemia by MCV and RDW. In the pilot study for estimating the prevalence of anemia according to the type of b, the prevalence rate was higher in organic solvent workers than in public officials as 10.9% and 4.1% respectively. There were statistical significance in the value of hemoglobin, hematocrit, MCV, MCHC, platelet count, ESR, RDW between the two study groups with more severe anemic tendency in organic solvent workers. The type of anemia in organic solvent workers was microcytic and anisocytic with the mean value of $68.28{\pm}8.3fL$ of MCV and $19.1{\pm}4.0%$ of RDW.

고관절경을 시행하는 집도의사는 관절경을 통해 관찰되는 정상 고관절의 해부학적 구조물에 대한 정확한 지식과 삽입구 위치에 대한 숙지를 통해 환자의 증상과 비정상 관절경 소견을 임상적으로 연관 시키는 것이 중요하며, 적절한 환자의 선택과 고관절경의 술기에 대한 항상성을 유지할 수 있어야 최소 침습적인 술기의 장점을 가지고 있는 고관절경의 만족할 만한 치료 결과를 기대할 수 있다.

In this study the reactor design procedure and method of solid-solid-gas chemical heat pump system using STELF technology were investigated. For manufacturing IMPEX block which is the kernel of reactor, proper salt pair should be selected, and equilibrium temperature drop and COP should be examined for selected salt pair. Moreover, apparent density, residual porosity, and graphite ratio should be calculated to give minimum block volume and mass, and maximum energy density without causing heat and mass transfer problems. Since heat exchange area can be changed with operating condition, reactor diameter, length, and stainless steel thickness should be decided for desired specifications. These procedure and method were applied to the case study of 6kW cold production and 8 hours storage capacity reactor.

Monolithic three-way catalysts were aged with different mileages on an engine dynamometer. These catalysts were subsequently evaluated on an engine dynamometer to examine the effects of air/fuel ratio set point, temperature, and air/fuel ratio amplitude and frequency on the conversion efficiencies for NOx, CO, and HC. For this test, dual oxygen sensor method, which utilizes a comparison. between an upstream oxygen sensor and oxygen sensor placed downstream of the catalyst. is used under steady state operating conditions. It is found that the amplitude and frequency of air/fuel ratio closed-loop control system affects the NOx. CO, and HC conversion efficiencies greatly. In this study, a new parameter which can be used as a measure of catalyst performance is proposed, and it is found that this parameter qualitatively matches well with the HC conversion efficiency of catalyst.<br/>

본 연구는 장애인의 건강관련 삶의 질이 어떤 형태로 유형화되는지 규명하고, 각 집단 유형의 특성을 파악하여 장애인의 건강관련 삶의 질을 증진하기 위한 실증적 기초자료를 제공하기 위해 수행되었다. 이를 위해 한국보건사회연구원과 국민건강보험공단의 한국의료패널에서 장애인 863명을 대상으로 이들의 건강관련 삶의 질 유형화 분석을 실시하였다. 장애인의 건강관련 삶의 질에 대한 유형을 확인하기 위해 잠재계층분석(Latent Class Analysis)을 사용하였으며 분석 결과, 장애인의 건강관련 삶의 질은 전반적 심각형, 통증관련 심각형, 전반적 안정형으로 분류되었다. 도출된 각 건강관련 삶의 질 유형별 특성과 유형화 결정요인을 확인하기 위해 X2검증, 다항로지스틱 회귀분석을 적용한 결과 세 유형 모두 사회경제적, 장애 및 건강행태, 심리적 특성변인별 차이점을 보였다. 연구결과를 토대로 장애인의 건강관련 삶의 질 유형에 관한 실천적 함의와 장애인의 건강관련 삶의 질 증진을 위한 실증적 개입방안에 대해 논의하였다. The purpose of this study is to define types of the disabled’ quality of health life, to find the characteristics of each different group, and thereby to provide the practical basic material for improving their quality of health life. To achieve that, this study analyzed types of the quality of health life that 863 disabled persons had in the Korea Health Panel of National Health Insurance Corporation and Korea Institute for Health and Social Affairs. To find types of the disabled’s quality of health life, this study utilized Latent Class Analysis. As a result, their quality of life was classified into general severeness type, pain severeness type, and general stability type. To find characteristics of each drawn type and determinants of each type, X2 test and multinominal logistic regression analysis was applied. As a result, these three types had differences in terms of social and economic, disability and health pattern, and psychological characteristic variables. Based on the study results, practical implication of types of the disabled’s quality of health life and an empirical intervention plan for the improvement their quality of health life were discussed.
