도시지역내 쓰레기 매립지의 관리문제는 지방 자치단체와 도시 주민에게 있어 중요한 관심사로 대두되었다. 계속되는 쓰레기 매립지의 수용력 감소와 기존 쓰레기 매립지에 관련한 시민의 공중보건 및 환경 문제에 대한 자각은 쓰레기 매립지 선정과정에 있어서의 제약 요인으로 새롭게 제기되었다. 위치선정 과정상에는 그 밖에도 부가적인 제약 요인으로서의 사회적, 기술적 측면의 문제와 함께 계획과 보상비용 증가라는 문제가 복잡하게 얽혀있다. 적지선정에 과정에 지형공간정보시스템의 공간 데이터베이스 환경과 각종의 모델링 기능을 연결함으로써 대상지내의 쓰레기 매립 개발 적지 및 후보지선정을 빠른 시간내에 적은 비용으로 수행할 수 있을 것으로 판단된다.

We analyzed total protein (TP), albumin (AL), aspartic aminotransferase (AST), alanine aminotransferase (ALT), urea nitrogen (UN), creatinine (CRE) and serum protein electrophoretic fractions in sera of rural elderly patients to evaluate the health status in rural elderly patients. We observed that the frequencies of patients showed lower level of total protein, albumin, and both total protein and albumin than them of reference range were 20.3%, 22.8% and 19.0%, respectively. The rates of patients showed higher level of AST, ALT, both of AST and ALT, UN, creatinine and both of UN and creatinine than them of reference range were 33.8%, 40.0%, 30.0%, 17.7%, 15.2% and 7.9%, respectively. Comparison of protein fractions of each patient to reference range showed that 77.2% of patients showed normal in all of patterns. Few of patients showed abnormal pattern in albumin (13.6%), ${\alpha}1-globulin (0.0%),\;{\alpha}_2-g10bulin(1.1%),\;{\beta}-globulin(1.9%)\;and\;{\gamma}-globulin(6.2%)$. These data suggest that many of rural elderly patients may suffer from heart, liver and kidney diseases. The serum protein fractions are not typical criterion to evaluate the disease, but production of proteins in rural elderly patients may be affected by liver disease and kidney disease.

This study applied the parametric bootstrapping method to analyze whether there was a change in the production efficiency of institutions under Ministry of Oceans and Fisheries. This study used input and output oriented productivity simultaneously. In particular, the productivity was estimated through 95% confidence interval derived by 2000 times re-sampling process. The results of the study showed us a reduction in overall total factor productivity by 24% between 2009 and 2013, and 7% of decreases in productivity annually. A recent conditions of an external economic shocks brought a 28% downward shift of production function. In this study, public institutions were divided into three types, which were public, quasi-government, and other public institutions. There were approximately 13%, 1%, and 5% decreases in total factor productivity per each. In analyzing the productivity each of 14 institutions, approximately DMU4 and DMU6 had 4%, and 5% increases in productivity per each. While DMU14 showed us no changes in productivity, all of the other 10 DMUs were estimated the decreases in productivities.

We studied bird communities among in rice field (46 plots), short grallland (47plot), and tall grass mixed shrub (21 plots) during dry season, January 2007 in Boeung Prek Lapouv (BPL) Important Bird Area, Mekong Delta, Cambodia using the point-count method. Water depth, vegetation height and shrub density were significantly different among the three study areas. We recorded, 60 bird species, of which 13 differed significantly among habitats. Landbirds such as Grey-breasted Prinia (Prinia hodgsonii) and Oliver-black Sunbird (Nectarinia jugularis) were much more abundant (P<0.0001) in the tall grass mixed shrub, whereas the Sarus Crane (Grus antigone), herons and egrets were more abundant in the short grass (P<0.05). Bird species richness and species abundances were not significantly different among habitats. Bird species diversity (H') was higher in grasslands than in rice fields. Mosaic habitat matrix, such as rice field, short grass, and tall grass mixed shrub, should be maintained for the extend and quality of wetlands, and the prevailing human-land use patterns, appear adequate and conductive for waterbirds in the Mekong Delta, Cambodia.

During the 5 years period(93-197) of Seoul racecourse Thoroughbred racing, 2i963 holies took an active part in Seoul Racecourse and 61,181 horses entered the racing.400 horses(305 : 1 time, 76 :2 times, 19 :3 times, total : 514 cases) had bled(EIPH) from their nostils after their races. Incidence of bleeding horses from the 21963 racehorses was 13.5%, and incidence of bleeding cases from the 61,181 horses was 0.84%. The average racing frequence (1.05 times/1 month) of bleeders was more than that(0.8 times/1 month) of total race-horses. There was tendency to higher incidence of bleeding at older in age, female in sex, England/ Ireland horses in origin, higher grade in performances heavier in body weight increased, larger in weight to be carried, mid or longer in racing distance, handicap race, spring in season. Relationship did not exist between bleeding and respiratory disease. These results suggested that frequent entering into the race should be controlled. And body weight regulation with conditioning is recommended far reducing incidence of EIPH. It is supposed to prevent bleeding that decrescent performance horses should not be entering long distance or handicap race.

Laser welding is widely used for precision welding because of superior mechanical properties and high productivity. Generally the accuracy of the welding is determined by the distribution of the bead which is affected by the structural vibrations of the equipment. This study was originated to stabilize a laser welding machine to minimize the bead distribution for the precise joining. The structural properties of the laser welding machine have been investigated to analyze the major factors of the vibrations to cause the bead distribution. The ideas for the design improvement have been applied to the simulation model to identify the effects and further to achieve the stability design and to minimize the bead distribution. The result shows that a few simple design alterations can substantially suppress the structural vibrations and improve the welding accuracy. The procedure used for this study can also be applied to similar welding equipments for improving the structural stability and the welding accuracy.

The purpose of this study was to investigate the policy demands of the family sector for work-family balance, with a focus on the child care and household labor provisions. For empirical analysis, data were collected from 197 dual-income families with at least one young child under age 10 in the metropolitan area via self-administered questionnaires. The major findings of this study were as follows. First, child care provisions for working mothers and fathers were insufficient and unfair, and the ratio of child care provisions offered by familial child care network was high. The characteristics of child care provisions for working parents were associated with family structure, working conditions, and demographic variables. Second, household labor provisions for working mothers and fathers were also insufficient and unfair, and the ratio of socialization was high. Third, the level of family satisfaction varied by the level of child care and household labor provisions, respectively, controlling family structure, working conditions, and demographic variables. The empirical results of the study provided policy implications for work-family balance.
