  • 인공우주물체의 추적 및 관측을 위해 LX-200 12인치 망원경시스템을 도입하여 시스템의 구동부(모터, 모터드라이버, 모션컨트롤러)를 응답특성이 빠르고 능동제어가 가능한 것으로 개선하였다. 또한, PC를 이용하여 대상물의 실시간 궤적정보를 계산하여 모터 드라이버 내의 PID 제어기에 신호를 제공하였고, 명령신호 제어주기도 20ms까지 줄였다. 그 결과, 가대의 구동속도는 $18^{circ}/sec$로 향상되고 상용시스템보다 응답속도가 빠르며 대상물의 이미지 관측시 flipping 현상을 최소화하는 시스템을 개발하였다.

  • Artificial islands, installations and structures have been used as a major means for ocean development and management since the early 20th century. The International legal regime to regulate the man-made offshore structures also have evolved and the UN Convention on the Law of the Sea (UNCLOS) acts as a basic international instrument for that purpose. Although the Convention includes more detailed provisions on man-made offshore structures, there are some legal issues regarding jurisdiction of coastal State on the man-made offshore structures in the Exclusive Economic Zone (EEZ) or on the Continental shelf. For this reason, this article begins by reviewing the 1958 Convention on the Continental shelf and the UNCLOS by focusing on the EEZ and the Continental shelf regime governing the man-made offshore structures. It next examines some controversial international legal issues that have emerged from the regulation of man-made offshore structures in the EEZ or on the Continental shelf. This is followed by a review of the Korean domestic laws regulating artificial islands, installations and structures in the EEZ or on the continental shelf. Finally, it closes by summarizing the findings of the above examinations, and suggests some recommendations for future works.

  • The purpose of study examined of historical changes of western men's nightclothes from middle ages to the modern ages and analyzed functions and features of men's nightclothes. This study presented meaning and importance of men's nightclothes. The method of study researched the many literatures and internet sources. Until medieval age, men slept naked or in a day-shirt. In the 16th century, a nightshirt was worn in bed. A night-cap was usual, in rather more elaborate form, also worn by day in the house, and even outdoors. In the 17th century, nightshirt was elabrated with ruffles and lace. The nightshirts of 18th century, resembled the day-shirt except that it was slightly longer and fuller in cut. The turn of 19th century, men weared nightshirt with a high folding collar, one button and night-cap of jellybag shape. In the early 19th century, nightshirt had a plain turned-down collar, buttoned at the neck. A night-cap with colored tassel was usual. The middle of 19th century, a nightgown was reaching to the ankle. Pyjamas, in the 1890s, were steadily replacing the nightshirt, before long pyjamas had become generally accepted in place of the nightshirt. A pyjamas which preseverved his male dignity by giving him trousers. Man's ingenuity also modified his nigntclothes so that these took on sexual characteristic. In 20th century, the fabrics had become lighter in weight, and the choice of materials wider. By 1930s, nightclothes had become the man's most colorful garment.

  • This study was carried out to estimate the recreation carrying capacity of lawn areas in parks. Recreation carrying capacity in this study is composed of two parts, ecological carrying capacity. This part deals with the psychological carrying capacity, based on the perception of crowding level and recreation satisfaction of users. The survey was conducted at the lawn areas of Doturag World and Seorabul Plaza in Bomun Resort Complex in Kyungju. The major results are as follows: 1. As the result of regression of regression analysis between use density of lawn area and level of perceived crowding, the capacity was estimated as 60.0㎡ man. 2. As the result of regression analysis between use density of lawn areas and total recreation satisfaction, the capacity was estimated as 48.5㎡/man. 3. As the result of regression analysis between use density of lawn areas and satisfaction to use density, the capacity was estimated as 63.2㎡/man. 4. As a conclusion, the psychological carrying capacity was estimated as 60.0㎡/man. And this value is based on user's perception of crowding and recreation satisfaction level for each use densities.

  • 본 연구는 Debaryomyces sp.가 생산하는 ${\alpha}-galactosidase$의 mannobiose-sepharose 담체합성법에 의한 affinity column chromatography를 수행하여 효소정제, 효소 화학적 성질 및 galactosyl mannooligosacchrides에 대한 기질특이성 규명을 주요 목적으로 하였다. 배양시간별 활성과 pH의 변화에서 배양시간 40시간부터 활성이 증가하고 있으며, 70시간에서 25.8unit/ml의 최대활성을 나타내고 있으며, 배양초기 pH 6.0에서 시작되어 배양말기에는 pH 8을 나타내는 pH의 변화를 보였다. 최적 pH는 4.0, 최적온도는 $60^{\circ}C$이며 $pH\;3{\sim}4.5$에서 100%의 잔존활성을 나타낸 반면 pH 8.0에서는 20%로 급격히 감소하였고. 온도안정성에서 $30{\sim}50^{\circ}C$에서는 100%의 잔존활성을 나타내었으나 $70^{\circ}C$ 이상에서는 20% 이하의 잔존활성을 나타내었다. $Hg^{2+}$에 의해서 54%, $Ag^{2+}$에 의해서는 85%로 저해되었으며, 그 이외의 이온에 대해서는 큰 영향을 받지 않았다. Debaryomyces sp.유래 ${\alpha}-galactosidase$는 24시간 반응 후 melibiose, $Gal^3Man_3$를 완전 가수분해 하여 각각 galactose와 glucose, galactose와 mannotriose로 분해되었으나 $Gal^3Man_4$에 대해서는 12시간 반응시켜도 기질로부터 galactose 유리가 불가능함이 확인되었다.

  • 본 연구는 학문적 연구 대상에서 소외돼 온 텔레비전 드라마 작가에 관한 후속 연구로, 멜로드라마 <사랑과 야망>과 <내 남자의 여자>의 여주인공을 중심으로 김수현 작가 의식 저변을 탐구하는데 그 목적이 있다. 김수현 작가는 자율 통제 의식에 의해 텔레비전 드라마 장르에서는 보기 드물게 홈드라마와 멜로드라마의 장르 선긋기를 명확히 하고 있으며, 상대적으로 멜로드라마에서 두드러진 작가 의식이 발화된다. 본고는 멜로드라마를 통해 발화되고 있는 김수현 작가의 의식 심층을 탐구하기 위하여 라깡의 주체와 욕망이론을 적용한다. 라깡에게 주체는 언어의 기호작용에 의해 형성되지만, 언어의 상징계는 불완전함으로 주체는 '존재'로부터 '소외'되고 '결여'와 '분열'에 시달리는 주체이다. 이 주체는 타자와의 관계 속에 타자의 욕망을 욕망하고, 욕망의 대상이 되기를 원한다. 이 욕망은 전일체, 완전히 조화로운 상상계, 완전한 사랑을 끊임없이 요구하고, 상징계의 불완전성을 거부함으로써 지속된다. 이 거부 과정에는 무의식적 환상이 작동한다. 라깡은 '환상 가로지르기'와 '분리'를 통해서만 주체의 진정한 탄생, 해방이 이루어진다고 말한다. 20년 세월의 간극 속에도 <사랑과 야망>과 <내 남자의 여자> 속 두 여주인공의 갈등의 요체는 동일하다. 인간의 근원적이고 본질적인 주체의 결여와 욕망이 그것이다. 완전한 사랑에의 이상 추구, 그러나 현실에서는 불가능하며, 주체의 소외와 결여를 낳는 욕망의 고리 속에 주체의 진정한 해방, 자유를 향한 물음이 김수현 작가 의식 저변에 자리한 영원한 테제이다.

  • The study was designed. to analyse the factors effecting to smoking and drinking of community people in rural area. The study has been surveyed through interviews by trained college students for 1,846 residents who live in rural area(Eup or Myun office is located)for 20days(from 3rd. to 22M. in August, 1988) The summary and conclusions are as follows. 1. The number of answers on the questionaires was 1846. And the percent of man was 55.7 %(woman 44.3 %). Among age group 20-29 years group with 30.4 % was larger than any other group. Anaverage age of answers was 38.6 years. 2.In the period of residence, 21.5 % of the residents lived within 5 years(This group was larger than any other group). In occupations, workers in agriculture and fishing was more than other job occupants. In education, the percent of high school graduates was 44.0 %(higher than any other group) 3.The smoking rate of rural residents was 41.8 %and man's smoking rate was 76.0 % (woman's smoking rate was 7.6 %). These rates were higher than the rates in 1985 (The smoking rate of nation was 32.0 %). First of all, woman's smoking rate increased rapidly 4.As for smoking amount, in male 52.8% of smokers smoked a cigarette case (20 cigarettes) in a day, and 16.9 % of smokers smoked more than one cigarette case. In female 42.5 % of woman smokers smoked a half case in a day and the rate of non-smokers diminished to 77.8 % 5.The rate of non-smokers in 21-29 years group was higher than any other group and a smoking rate increased as an age increased. However, a smoking amount decreased as an age increased. This suggests that people are more concerning about their health as their ages increase.. 6.The smoking rate of college graduates was 58.8 %(higher than any other group) and in a smoking amount 36.4 % of college graduates, 29.8 % of high school graduates smoked more than a cigarette case in a day. This shows that people in a higher education group smoke more than those in other groups. 7.As for non-smoking rate, students, service job workers, company employees, and teachers was 54.1%, 43.4%. 40.1% and 39.5%. respectively. As for smoking rate, workers in agriculture and fishing was the highest level of all job employees. Public officers smoked less than the workers in agriculture and the smoking rate of teachers was less than that of public officers. with regard to smoking amount. above one cigarette case in a day was 39.9 % in public officers, 39.2 % workers in agriculture and fishing, 37.9 % in businessmen, 34.2 % in teachers, 31.9 % in service job employees and 31.6 % in a company employees. 8.The variables which had an effect on smoking were sex (B=.1701), job(B=.1688), education(B=.1671), age(B=.1125). These variables were significant in P<0.05 statistically. Explanatory variance level was 19% 9.The drinking rate of community residents was 61.8% and man's drinking rate was 81.7%(woman's drinking rate was 38.9%). As drinking rate 18.0%(the highest rate) of man drinkers drank 3 bottles of beer in a general drinking and 12.1% of them drank more than 10 bottles. 12.1% (the highest rate)of woman drinkers drank 2 cups of beer. The rising rate of woman's drinking of alcohol was remarkable. 10.Each non-drinking rate of age groups was 27.6% (in 20-30 years group), 28.0% (in 30-39 years group), 28.9%(in 40-49 years group) and 32,6%(in 50-59 years group), 10,7%(the highest rate) of 20-29 and 30-39 years groups drank above 3 bottles. 7.5% of 20-29 years group and 7.7% of 30-39 years group drank above 10 bottles. In 40-49 years group, 14.4 % of them drank a bottle and 8.1% of them drank above 10 bottles. In 50-59years group, 14,2% of them drank 2 bottles and 5.3 % of them drank above 10 bottles. This shows that a drinking rate decresed as an age increased. 11.Non-drinking rate was higher as an education level was lower. Each non-drinking rate of non-educated group, elementary school group, middle school group and high school group was 41.0 % of high school graduates and 14.5 % of college graduates drank 3 bottles of beer. 9.7 %(the highest rate) of college graduates drank above 10 bottles, in general drinking. 12.Each non-drinking rate of businessmen, farmers, service job workers, and students was 31.3%, 28.2%, 26.8% and 25.9%. However, Each drinking rate of public officers, company employees and teachers was 73.3 %, 72.2 % and 68.4 %. This tells us that the drinking rate of mental workers is higher than that of physical workers. 14.9 % of farmers and 14.4 % of public officers drank 3 bottles at a time. 10.5 % of teachers and 9.9 % of public officers drank above 10 bottles. 13.The variables which affect on drinking were sex(B=.1545), education(B=.1476), job(B=.1064), and age(B=.1052). These variables were significant in the level of 0.05 % and explanatory variance level was 18 %. 14.Government have to educate people and demonstrate the health hazards caused by smoking and over-drinking. Especially, No-smoking campaign for woman and education not to over drink for professional job workers are necessary.
