In a previous study, we developed a new food additive as an egg yolk antibody (IgY) against carbohydrate digestion enzymes for the regulation of blood glucose level and weight control. The IgY delayed and decreased the increment of blood glucose level after administration of sucrose in human being by 30% in 20∼30 min. We also developed a lipase inhibitor as a water extract of two kinds of herb, Platycodon grandiflorum and Solanum melongena. Twenty three volunteers were subjected to the intake of the egg yolk IgY plus the herbal extracts for 50 days. In average, the treated subjects appeared to lose 1.96 ㎏ of body weight and 3.4 ㎏ of body fat mass during the treated period. Furthermore, Panniculus adiposus and breech size were significantly decreased during the experimental period. Above results suggested that the administration of the dietary additives composed of egg yolk IgY and natural herbal extract improve the obesity by the decrement of body weight and body fat mass.

An algorithm to automatically extract coordinate and time information from optical observation data of geostationary orbit satellites (GEO satellites) or geosynchronous orbit satellites (GOS satellites) is developed. The optical wide-field patrol system is capable of automatic observation using a pre-arranged schedule. Therefore, if this type of automatic analysis algorithm is available, daily unmanned monitoring of GEO satellites can be possible. For data acquisition for development, the COMS1 satellite was observed with 1-s exposure time and 1-m interval. The images were grouped and processed in terms of “action”, and each action was composed of six or nine successive images. First, a reference image with the best quality in one action was selected. Next, the rest of the images in the action were geometrically transformed to fit in the horizontal coordinate system (expressed in azimuthal angle and elevation) of the reference image. Then, these images were median-combined to retain only the possible non-moving GEO candidates. By reverting the coordinate transformation of the positions of these GEO satellite candidates, the final coordinates could be calculated.

Arteriovenous fistula of uterus is a very rare cause of massive uterine bleeding. However, it is important to make a rapid and precise diagnosis when it does occur, because life-threatening massive vaginal bleeding may occasionally be a symptom of this disease. Uterine curettage or surgical trauma can cause vascular abnormalities, including pseudoaneurysms, acquired ateriovenous malformations, ateriovenous fistulas, and rupture of vessels. The diagnosis is made by angiography, and gray scale ultrasonography, color and duplex doppler ultrasonography, computed tomography, magnetic resonance imaging is helpful. Ultrasonography is the most commonly performed initial imaging examination for evaluation of abnormal uterine bleeding. Color and duplex Doppler US is an appropriate modality for the detection and diagnosis of uterine ateriovenous malformations and for follow-up after embolization. Transcatheter embolization has replaced hysterectomy as the treatment of choice in women wish to retain thier fertility. A case of arteriovenous malformation of the uterus which was diagnosed by ultrasonography. So reported this case with a brief review of the literature.

The purpose of this study is to analyze the terms, Leisure, Recreation, and Play in an attempt to explain the complex phenomena of the terms. It is achieved by reviewing past literature. The reasons for developing definitions and ways of measuring these terms are to help both the practicing leisure professional and those who study the leisure phenomena. By defining and measuring these terms, we can more accurately predict the consequences and actions of our work as leisure professionals. One can also be provided a better understanding of the phenomena of the terms. For the research methodology, a descriptive study, which is to present a detailed picture of the phenomena hilt does not attempt to test or build theoretical models, was used for this study. On the basis of the results analyzed in the study, findings were made as follows. Leisure can be viewed from a number of different perspectives. Some theorists suggest that leisure is an element of time, whereas others have perceived it as a set of unique activities in which individuals participate. Recreation can be viewed as a wholesome activity in which individuals participate in their leisure time. Recreation is a more commonly used and understood term among the general public than either leisure or play. Play is an exceedingly interesting, yet diverse and different topic to identify. Many theories have emerged to describe play. However, today it has no generally accepted explanation or definition. Unfortunately, confusion interpreting leisure, recreation, and play was found in this study. Based on the results of this study, this researchers offer one possible view of the terms for the further studies. The new terms defined are provided.

Apical periodontal cysts correlate to dental caries, and derived from the epithelial rests of apical granuloma. The lesions are histologically characterized by infiltrates of monocytes/macrophages, lymphocytes, plasma cells and mast cells. In addition, cholesterol crystals and foam cells are found. The aim of this study was to investigate the relationship between chronic inflammatory cells, cholesterol crystals and foam cells. The results obtained were as follows : 1. In all apical periodontal cysts, mild to severe number of inflammatory cells could be observed, while foam cells and cholesterol crystals were found in varying number. 2. The cholesterol crystals were not always associated with foam cells. 3. The cholesterol crystals appeared as long narow spaces with pointed tips and cluster formation. 4. The foam cells and choesterol crystals surrounded by lymphocytes, plasma cells, and erythrocytes, hemosiderin pigments and giant cells were observed. 5. Vast number of the cholesterol crystals and foam cells congregated in connective tissue, less frequently crystal mass eroded the epithelial lining and empties the crystal into the cystic cavity. From above the results, it was found that cholesterol crystals and foam cells are characteristic findings and correlated to inflammatory reaction in apical periodontal cyst. It suggested that inflammation closely related to cholesterol crystals and foam cells.

본 연구에서는 수질오염이 산업폐수, 가계하수 그리고 토지유출수의 3가지 요소에 의해서 발생된다는 가정을 바탕으로 환경수준과 경제활동 사이에 존재하는 상반관계를 낙동강유역을 대상으로 분석하였다. 분석에는 다지역 투입산출모형이 이용되는데 이때의 다지역 투입산출표는 행정구역이 아닌 유역권을 기준으로 작성되었고 이를 바탕으로 목표년도(2010)의 낙동강 유역 수질수준을 예측하였다. 또한 수질을 개선하기 위해 두가지 정책 즉, 자체처리시설을 증설하는 정책과 종말처리장을 증설하는 정책을 제시하고 이것을 정책에 소요되는 비용과 정책효과 측면에서 평가하여 지역별 가장 효율적인 정책을 제시하였다. 마지막으로 GRDP에서 수질오염에 의해 발생하는 환경비용을 고려한 ERDP(환경적으로 조정된 지역내 순생산)를 제시하였다. This paper analyzes the trade-off relationship between environmental quality and economic activity, specifically focusing on water pollution of Nakdong-river region, Korea. The analysis begins with the assumption that water is contaminated by three pollutive sources, production sector, household sector and land surface water. Three-region input-output table is constructed based on the Catch basin area not administrative area for analysis. Water polluting level of Nakdong river region in the year 2010 is forecasted taking into account the pollutive sources. Also, two types of environmental policies are presented and assessed in terms of pollution abatement costs and effects. Finally, the interest in this paper stems from recent advances in so-call EDP(environmentally adjusted net domestic product) which reflects environmental costs in GDP. The paper attempts to calculate ERDP(environmentally adjusted net regional domestic product) by incorporating EDP into regional level with the assumption that environmental costs are represented by water pollution abatement costs.

A hand-arm vibration syndrome, local vibration illness, occurs in some workers who use hand held vibration tools. It consists of white fingers, diffusely distributed finger neuropathy, pain in the hand and arm, and a small excess risk of osteoarthritis. This study is aimed to identify effective methods to confirm local vibration illness among various health exams, which are mentioned in worker's special health exam regulation. In addition, this study is aimed to quantitatively assess the daily vibration exposure level as a major determinant of vibration illness. The subjects, 46 vibration workers, were selected according to the results of the first special health exam about vibration hazards at shipbuilding industry in 1997. They all had experiences of work related blanching of fingers. Fifteen controls, who had no vibration exposure at all, were also recruited to compare their test results with the results of vibration workers. We adopted I subjective and 6 objective tests to evaluate the effectiveness and feasibility for confirming local vibration illness. These tests were history taking of subjective symptoms according to the Stockholm classification, checking blood pressure of finger, checking grasp power, checking finger skin temperature, nail-bed pressing test, vibration perceptional threshold test, and skin prick test for pain perception. Among these, checking skin temperature, nail-bed pressing test, and vibration perception test included cold water provocations. We also estimated some vibration exposure levels of hand held vibration tools by using previously published data from one automobile company. In conclusion, history taking of subjective symptoms according to the Stockholm classification, nail-bed pressing test, and vibration perceptional threshold test were discovered to be effective to diagnose local vibration illness. Furthermore, vibration perceptional threshold on right fingers showed a dose-response relationship to daily vibration exposure levels. The parameter β was 0.0005(±0.0002), and statistically significant by REM(random effects model).
