이상준,박미연 부산대학교 환경문제연구소 1994 環境硏究報 Vol.12 No.-

Over the past '70's, our country has carried out a series of economic development plans successfully. On the other hand, however, as side-effects of industrialization, it has caused so many problems, the most serious one of which is environmental pollution. Therefore, this study, considered the vital state of environmental pollution and the importance of environmental reservation today, is performed through the experimentation and questionaires to have a through grasp of the real environmental state around Eulsuk-do located in Hadan-dong, Saha-gu, Pusan and to make it more comfortable circumstance. The subjects are dwellers living around Eulsuk-do and its regional administrative officials. The result are as follows; 1. General Water Analysis This experiment was carried out to evaluate the water quality of Nagdong river around Eulsuk-do. Water samples were collected from 3 stations from December 1993 to February 1994 (see Fig. 1). Water temperature, pH, chloride ion, DO, BOD, COD, SS were observed to evaluate the water quality. The month average concentration of general items at each site was 8.3∼11.0(℃) in temperature, 6.70∼7.61 in pH, 0.05∼1.32(%) in ??, 9.1∼10.8(mg/l) in DO, 3.33∼7.00(mg/l) in BOD, 6.02∼21.04(mg/l) in COD, 18.0∼65.3(mg/l) in SS. 2. Survey Analysis They pointed out in the questionaires over the state of its natural environment that it is badly contaminated mainly by water pollution(Regional administrative officials : male 88.6%, female 90.5% ; Dwellers : male 94.6%, female 100%). In the question of living environment, they replied that air pollution, water pollution, noise, vibration and stinky small are seriously excessive, and that the remarkable fact of its living environment is that surrounding s of Eulsuk-do are changed into the resort for recreation. And they pointed out the social and cultural environment around Eulsuk-do is insecure, dirty uncomfortable and low-cultured.

프로축구 유소년 육성 방안 고찰

이상연,김종환 중앙대학교 스포츠과학연구소 2002 體育硏究 Vol.- No.16

The purpose of this study was to develop the system in order to train up youth soccer players. The study provides a great system for training skillful players. It also aims to offer the long term method for training up youth players with special needs to learn new skills, build physical fitness and self esteem. Professional teams should build up kids and youth soccer teams to produce good players. They should have more Interest in the youth soccer team which has lots of different levels according to age. The professional teams can provide an opportunity to continue development at each age group to reach the highest level possible under the guidance of highly qualified coaches. Therefore optimizing performance of the player at each level proving the highest potential in the age group(16-18). In order to produce the best young players, the youth soccer team must be managed by a professional team. The way matches are played between school teams should also be changed from tournament style play to the league system(this would put emphasis back on study). Thus I would like to suggest the following factors: First, school as well as professional teams should manage youth soccer teams. Second, at least until 16, the youth player should take part in "gular classes"ike ordinary students. They should only train after school and not in "p-Sook"intensive soccer training camp). The training camps must be established only in summer or winter vacation. Third, we should increase the number of local games and reduce national tournament games. The number of games should be evenly distributed on Saturdays or on Sundays by local leagues. Fourth, Acceptance to higher level of play such as high school or university should not depend on the winning and losing record of the team. This system must be changed to individual peformance of the player. Fifth, we have to provide more opportunities for school soccer teams to play against youth soccer teams which are managed by professional teams to raise the level of skills and competition. These factors as I mentioned can improve our school soccer system. We should form a youth soccer federation so this federation can organize matches between teams and manage them. It is helpful to the youth players to acquire new skills as well as to build their physical fitness. The league system should be formed according to the age. It is very useful to train the good young players.

Platinum-Cobalt alloy thin films were deposited on Al_(2)O_(3) substrate by magnetron cosputtering for RTD with wide temperature range. We made Pt-Co alloy resistance patterns on the Al_(2)O_(3) substrate by lift-off method and investigated the physical and electrical characteristics of these films under various conditions, the input power, working vacuum, annealing temperature and time, and also after annealing these films. The resistivity and sheet resistivity of these films were decreased with increasing the annealing temperature. After the annealing treatment at 800℃ for 60 min, the resistivity and sheet resistivity of Pt-Co thin films was 15μQ·cm and 0.5Ω/□, respectively and the TCR value of Pt-Co alloy thin films with thickness of 3000Å was 3740ppm/℃ in the temperature range of 25-600℃. These results indicate that Pt-Co alloy thin films have potentiality for the RTD with wide temperature range.

브루셀라증은 전 세계적으로 발생하는 인수공통 전염병중에 하나로서, 본 증례는 국내에서 감염된 가축에 대한 노출력이 없는 집단에서 현증 브루셀라증이 발생한 첫 증례이기에 문헌 고찰과 함께 보고한다. 또한 환자가 근무하였던 축산물 부산물 시장에서 역학 조사를 실시하여, 현증환자 및 기감염자를 발견하여 축산물 부산물 시장 근무자에서 현증 브루셀라증이 발생할 위험성을 평가하였다. 역학 조사 결과 축산물 부산물을 다루는 일을 하는 사람들에서 감염된 가축과의 직접 접촉이 없이도 브루셀라증이 발생할 수 있음을 알 수 있었다. Brucellosis is a world-wide zoonotic disease. We report the first case of brucellosis in South Korea that is not related to direct contract with intected cattles. The patient had been working in the market of by-product, stock raising for twenty years and complained of 1-month history of fever, chill, and intermittent epistaxis. We confirmed brucellosis by anti-brucella antibody test and PCR. After 6 weeks' treatment with rifampicin and doxycycline, fever and chilling subsided, and, generalized weakness and oral intake improved. We performed seroepidemiology study against workers who were working in the same market as the patient. However, we couldn't find out other cases with seropositivity. We concluded that although the workers of by-product market have a risk of getting brucellosis, the risk is low.

韓國의 社會敎育行政에 관한 一硏究

趙誠一,金蓮起 建國大學校 敎育硏究所 1976 論文集 Vol.1 No.-

The conception of Social Education is summarized as follows: 1. In generality, Social Education means the exceptional activities of education, which is normally recognized as regular system of national education in school 2. The Social Education is systematic activities in education, clear and systematic national educational object and content and deviced educational activities. 3. The Social Education is ought to obtain with real life and improvable development. 4. The Social Education is an independent action of study by an active intention and it's objection of study to be attained by himself, but neither to be obligated nor impelled. The Social Education is achievable by not only the study in school, but adjusting by high level of industrial technics, variety of occupations, developments of industry and civilization, infliction of knowledgement and then, in this point in Korea it's neccessitated in order to adjust the transient social environment in a dire need. The administration of Social Education is the operation of cooperated and systematic group action in order to obtain the aim of social education in constitution and encourgement. For this objection it's attributable to the service activities as arrangement, instruction and supervision of man and materials. The characteristics of administration in social education ought to be considered the reactional method actively according to the variety and privilleges of social education assisting all groups activities of social education. In Korea the organization of administration in social education has not an indepentent law or regulation and attribute to a fragment. For instance, Central Organization has the social educational bureau and section in the Ministry of education and district organization has the social educational section and port in the educational committee in the provinces and cities. These educational bureau and section control the establishment, abolishment, instruction and supervisions of Junior Public school, High Public school, Private Seminary. Financial administration of Social Education maintains the expenses to support the activities of social education by the country or the public committee. The fund of social education has been allocated only 0.2% among of the budget of Ministry of Education, never been excess 0.2% of it. The problems of administration of social education to be summarized briefly as follow: 1) The legal law of social education has not been constituted in order to carry out and support the administration of social educational operations. 2) The organizations of central and district are not specialized for the efficiencies and liebilities. 3) The contents of administration of social education are not specified only inclined to govern. 4) The organizations attained social education are not in a close contact each other in publicity. 5) The fund support of budget for social education is too scanty. 6) The most of nation has scarce chances to obtain social education systematically and steadily. In this view point, we have to realize the important neccessity of social education and solve urgently those above problems in order to progress the development of our society.

The purpose of this study in to analyze hoe the physical activity of old adults influences on the mental health. The Simple Mental Testing was parcticed for the 100 of physical players and 60 of non-physical palyers, the total of 160, above 60 years old who live in the city of K. After that, we made a conclusion as the following; 1. When we compared the mental health of physical players with those of non-physical players, the physical activity of old physical players were certainly better than those of non-physical players in the field of somatization, fear, depression and anxiety. So, the physical activity had a good effect on the mental health of old adults. 2. When we analyzed the mental health according to the time of the physical activity, old physical players who exercised over 30 minutes were certainly better than those who did under 30 minutes in the field of somatization, fear, depression and anxiety. 3. When we analyzed the mental health according to the frequency in the physical activity, old physical players who exercised more than three times a week were better than those who did below three times a week in the field of somatization, depression and anxiety. 4. When we analyzed the mental health according to the period of the physical activity, old physical players who exercised over one year were better than those who did under one year in the field of somatization, fear, depression and indignation.

The principle of dietary modification in the diabetes is controling total calorie control, and take orderly meals, and should restrict ingestion of the saturated fat acid, and the simple sugar, and by taking green yellow veritable, seaweed, and fruit as sufficiency and take care of the ingestion of vitamin "B" type which would expedite metabolism, and it is better way to avoid the ingestion the salty food and alcoholic beverages. General exercise guidance will vecommend to take precedence over the medical diagnosis and an case history test before exercise begins, and the beginning of exercise, it start with light exercise, and gradually enhause intensity. Actual exercise program, will elevate an lungs function by the oxygenic exercise, and it is desirable exercise items that can consumable proper energy, and suitable for doing proper exercise by doing walk, stroll, jogging, go up &own the stairs, swimming, badminton, and mountain climbing etc. Exercise intensity is suitable with 30~65 of Vo<아래첨자>2</아래첨자> max, and actual exercise intensity decision is preferable for criterion of subjective symptoms, such as, a condition of sweating brow, sweating on the clothes, and the breathing is hard condition. The exercise intensity may be changeable according to the, pattern of diabetes, in case of pattern Ⅰ, the first step is 30% of Vo<아래첨자>2</아래첨자> max and about 10minutes; the second step is 40% of Vo<아래첨자>2</아래첨자> max and about 20 minutes; the third step is 40% of Vo<아래첨자>2</아래첨자> max and about 30 minutes; the fourth step is 50% of Vo<아래첨자>2 </아래첨자>max and about 30 minutes, and in case of pattern Ⅱ, it perform the first step is 40% of Vo<아래첨자>2</아래첨자> max and about 30 minutes, the second step is 50% of Vo<아래첨자>2</아래첨자> max and about 40 minutes, the third step is 65% of Vo<아래첨자>2</아래첨자> max and about 60 minutes, and the duration time per each step is about one week and both Ⅰ and Ⅱ type together, it is desirable to perform 5~7days. Above duration of exercise and its frequency determination will determine by the relation with the exercise intensity. Take snack that contains carbohydrate during exercise, and will discontinue the exercise when insuline activity is reach on high peak, and it is proper way taking 15~20g’s carbohydrate contained food against possibility of the low blood sugar occurrence after exercise. At last, it is much effective the exercise therapy is combined with the diet therapy for best diabetes treatment.

김상연,강신규 嶺南大學校附設 基礎科學硏究所 1988 基礎科學硏究 Vol.8 No.-

The β phase Fe₂? Ge(0≤χ≤0.32) intermetallic compound, fabricated by the melting method, have been studied by the X-ray diffraction in order to investigate the crystal structure and iron distribution. Iron atoms are located at all three sites 2(a), 2(d) and 2(c) of the B8₂type structure. The lattice parameters of the B8₂type structure are a?=3.995∼4.058Å and c?=4.991∼5.038Å. From the disagreement factor of the X-ray peak intensity, it is found that the iron atoms are located mainly at 2(a) site and Ge atoms are at 2(c)site. Therefore we conclude that the vacancies are randomly distributed in the unit cell.

핸드오프로 인한 TCP 재전송 타이머의 타임아웃 방지 방안

이상연,임행빈,정충교 강원대학교 정보통신연구소 1999 정보통신논문지 Vol.3 No.-

It will be occurred unacceptably long pause and intermittent disconnection states due to handoffs under the mobile computing environment. The current TCP interprets these handoffs as network congestion and excutes the congestion avoidance algorithms which degrade TCP performance. To prevent degrading TCP troughtput due to the unnecessary timeout problem of source retransmitter timer caused by handoffs, we propose EHN(explicit handoff notification) message algorithm which resets the value of retansmission timer. By adapting EHN, the TCP source can maintain the pre-handoff' congestion window size after handoffs and prevent the abrupt decrease of congestion window size caused by timeout. Therefore, this scheme improves the TCP performance more than the current TCP implementations during handoffs. With the computer simulation, we compare our EHN scheme with the current TCP scheme and fast retransmission scheme and prove the validation of EHN.
