To evaluate usefulness of application of MAST-CLA to indetify allergens, authors conducted MAST-CLA allergen-specific IgE assay and collected allergy related symptoms in 118 allergic patients diagnosed at Soonchunhyang University Chunan Hospital during October 1998 through January 2000. The results were as followings; 1. The mean (SD) age was 23.1 (±12.17) years old and teenagers accounted for 33.1% of patients. 2. The frequent allergic symptoms were sneezing (59.3%), rhinorrhea (53.4%), nasal stiffness (44.1%), itching sensation (24.6%), cough or sputum (16.1%), and eye symptom (8.5%) in order. 3. Among these subjects, 62.7% of patients revealed at least more than one specific allergen and 70.3% showed elevated total IgE levels by MAST-CLA. The three most frequent specific allergens were Dermatophagoides farinae (47.5%), Dermatophagoides pteronyssinus (45.8%), and house dust (30.5%). 4. While age was not significantly related to positive of both specific allergens and total IgE (P>0.05), sneezing and nasal stiffness were significantly associated with positive of specific allergen and total IgE, respectively (both P<0.05). 5. Total IgE increased with the number of specific allergens, but both specific allergen and total IgE were not significantly related to increases of allergic symptoms (P>0.05). In conclusion, our data suggest that MAST-CLA allergen-specific IgE assay is useful measure for identification of causative allergens in allergic patients, however, it is recommended that more specific allergic antigens should be determined and replaced or added to Korean inhalent panel of MAST-CLA.

남귀숙,장정렬,이광식,윤경섭,이상준 한국환경농학회 2003 한국환경농학회지 Vol.22 No.1

농촌지역의 도시화와 산업화에 따라 농촌 수질환경의 오염이 심화되고 있다. 경북 안동의 중산간지대에 위치한 만운저수지는 유역면적 23.8 km², 수표면적 0.4 km², 저수량 2.0×10^(6)m³의 부영양화 된 중규모 농업용저수지로서 1999년 수질환경특성조사를 실시하여 오염된 유사 농업용 저수지의 수질특성이해에 중요한 자료로 활용하고자 하였다. 만운저수지의 수질에 영향을 미치는 유역면적값(DA)/호수면적값(SA)의 비가 56.1로 국내 다른 농업용 저수지보다 높게 나타나 유역의 오염물질 부하가 높은 편이며, 평균 수심과 관련된 유효저수량(ST, m³)/수표면적(SA, m²) 비는 4.79로서 안동호, 팔당호보다 낮고 삽교담수호 등과 비슷한 값을 보여주어 부영양화의 잠재성이 높은 것으로 나타났다. 만운저수지의 수질조사결과 COD는 11.1 mg/L, 총질소 1.426 mg/L로 환경기준중 생활환경 Ⅳ등급인 농업용수 수질기준을 초과하였으며, 총인은 0.093 mg/L로 Ⅳ등급의 수질을 나타내고 있었다. 유입하천은 총질소(1.426~3.809 mg/L)가 비교적 높게 나타나고 있어 총질소에 기준한 수질개선 방안이 요구되었다. 식물성플랑크톤 조사결과 Oscillatoria와 근연종인 Lyngbya가 우점하였으며, 둥물성플랑크톤은 대부분의 지역에서 적조현상을 일으키는 와편모충인 Gynmodinium spp., 암색편모충인 Cryptomonas spp.이 우점하였다. 부영양화도지수(TSI)를 이용한 1999년도의 시기별 영양상태 변화는 9월에 과부영양상태를 보었으며, 연도별 TSI_(M)지수는 '96년, ‘97년에 부영양, '98년의 과영양으로 영양상태가 증가하였으나, 강우가 다소 많았던 '99년에는 강우의 영향으로 다소 개선되어 나타났다. 결론적으로, 저수지의 물리구조적 유역특성 및 수리학적 특성상 만운저수지는 부영양화에 취약한 특성을 가지고 있으며, 강우량에 영향을 받고는 있으나 전반적으로 부영양화도가 증가하는 추세를 보인다. 따라서, 이와 같은 추세변화를 정확히 인식하고 그에 적절한 대책을 마련하기 위해 농업용수 수질측정망 운영이 상당히 중요하게 인식되어지며, 수질환경 특성을 감안한 합리적 운영이 이루어져야 할 것으로 사료된다. Manun Reservoir, located in Andong district, has the capacity of 2 million tons in irrigation water supply with the drainage area of 23.8 km². Manua Reservoir is over fifty year old, and shallow in depth. The ratio of drainage area (DA) to reservoir surface area (SA) as an effective physical parameter on water quality was 56.1 and was higher than those of other agricultural reservoirs. The ratio of reservoir storage (ST) to SA in Manun Reservoir was 4.79, and the mean depth was below 8 m. Both ratios of DS/SA, total area (TA)/ST and ST/SA in Manua Reservoir were relatively higher than those in other agricultural reservoir and natural lakes in Korea. These physical parameters in Manun Reservoir, however, had a eutropic potential significance. Average of COD, TN, and TP in Manun Reservoir were 11.1 mg/L, 1.426 mg/L, 0.093 mg/L, respectively. In the inflow stream of Manun Reservoir, the TN (1.426~3.809 mg/L) was higher than those in reservoir. Only Lyngbya spp. was dominant in phytoplankton for this study period, and Gymnodinium spp., Peridinium spp., and Cryptomonas spp. were dominant in zooplankton. According to the Carlson's trophic status index, Manua Reservoir was eutrophic in 1996, 1997, and 1999, and hypertrophic in 1998.

As our result shows, a fatness comes from eating too much and is fundamentally owing to lack of exercises. (Pyung Woo Lee, 1990). Thus, scholars and practitioners recommend a diet and exercises. Since lack of exercises causes a fatness, a fatness can be prevented and cured by proper exercises. However one should be cautious in choosing and practicing a specific exercise. Inattentive exercise will not be effective and sometimes harms the knee joint and ankle. Several studies including Lee(1990) and Shin(1992) have shown that one should practice a relatively moderate exercise for a long time. A dietary treatment is also essential for the fatness. One should try to have a proper dietary habit from an early pfase of one's life. Finally one's effort to preyent and cure a fatness should de accompanied by his neighbors including peers and family.

It can be considered that the origin and development of Athletic Activities goes together with the Culture of Mankind in the wide meaning. At present, there exist about 160 countries in the world. All these countries take the policy on sports as the main principles and devote themselves to taking precedence in the formation of National physique and in the competition of International Sports. It is shown that the fundamental bloc, which currently forms the political tendency in the world, is largely brought from three types. That is to say, one is bloc of Freedom countries, another is that of Communist, and the other is, what is called, the new neutral bloc. However, the system of the most specially-compared two types is that of Freedom & Communist Bloc. This has characteristics that the former performs the policy based on the makes and executes the system upon the totalitarian and nationalistic basic idea. Also, in is not too much to say that the clear characteristics of these 2 bloc make the recent and modern age to the confrontation of idelogy, and acts the front contract through every scope in the extreme situations. Even if the Domino Circumstances as like the sinking of Communist bloc happen together with the downfall of ex. Soviet Union, we will need to understand that one of most dangerous countries in the world is North Korea and we, which confront with its line, must recognize these situations. Moreover, the South Korea and the North Korea are one Nation, but are divided by other power and authority, and it is well-known that the South Korea is threatened by the North Korea even today which half a century is approaching since our division of Nation. In these current situations, the research on part of politics, economy, society and education for the Unification will be important to us, and the person who majors in the Athletic Science performs the study on the Athletic Administration of Ex. Communist Countries and North Korea or their sports policy in the academic scope, and thus will understand their systems and the understanding how the physical educational is used to bring up any human. This purpose of this paper is to provide against the unification of the further-developed South Korea and North Korea, that is to say, demecracy and socialism, and then to support the insufficient points of each other, and then to look for the mutual union. Accordingly, we wit compare the Sports Group and Policy of South Korea and North Korea and then suggest the more-advanced development directions in this study.

As the technique of automobile industry is being advanced, the advancement of performance for vehicle is being required. In order to achieve this purpose, the study on the handling and stability which are produced by moving vehicle is carried out actively. Ability to predict vehicle performance using computer simulation is essential to reducing the development time for tire companies as well as car makers. From the previous research. we showed that handling simulation tool developed for J-turn and lane change maneuvers on ADAMS could be used in predicting the performance difference among tires with different specifications in vehicle mild handling behaviors. Through this study, some meaningful correlations were achieved. Also barriers to direct application of the simulation technique to tire development process and several technical problems that should be resolved were iden tified. In this results, ability to predict vehicle performance using computer simulation is essential to reducing the development time for tire companies as well as car makers.

國産高張力鋼의 熔接部의 機械的 性質에 關한 硏究

南勝義,金聖培,金錫胤 弘益大學校 1982 弘大論叢 Vol.14 No.2

A study has been performed on the mechanical properties and the micro-structure of the welded zone in the high tensile steel produced in Korea. The experimental results indicated that the tensile strength and the hardness were increased in welded zone. The micro-structure of the welded zone was finer than that of the base metal. It may be considered that the increase of the mechanical properties is due to the chemical composition of electrode being different from the base metal and to the structure getting finer through the course of solidification.

A1-Cu 合金粉末의 燒結品에 關한 時效硬化

南勝義,尹太鴻,趙誠秀 弘益大學校 1985 弘大論叢 Vol.17 No.2

During compaction and sintering premixed Al-Cu powders, the effects of green density, sintering temperature and sintering time on dimensional change and hardness in sintered specimens were discussed and the phenomena of all conditions during age hardening were examined. The specimens were sintered in nitrogen atmosphere at temperatures ranging from 560℃ to 620℃ for 10, 20, 30 and 60 minutes. The dimensional changes of specimens during sintering are occurred in no time as the sintering temperature increased, and the expansion is occurred largely as the green density increased. The magnitude of peak hardness to age hardening is similar to wrought parts.
