Recording the best tennis games on Video Tape, Huner 2, 4, 6 portable Video Cassette, which were held within and outside the country in the 1981. I analyzed the event situation of foreign professional players and domestic players having eight important factors of "serve and receive", "volley and passing shot", "lob and smash", "ground stroke and drop shot", and the like as fellows: Our players showed strengthen "serve" and "turn to" "net play" resolutely and minimize "error" and train "ground stroke" powerful and speedy. To have the above points we showed select a tall, young players and have them cast off giving the first consideration to game and train the basic skill steadily. Training the skill of "serve" and "volley" steadily without tenacity for victory and defeat. Our domestic players have ability to rival with foreign players and we look forward to gold medal in 1988 olimpic games which will be held in Seoul, Korea.

砲丸던지기에 關한 力學的 小考

金成龍 군산대학교 1979 論文集 Vol.1 No.1

The shot-put game, which is one of the far-reaching throws in the athletic sports of modern olympic games, is footlighted as a symbolic event with a discuss throw. And the new records are put on day by day. But since it is actual is Korea that the records are staggering, I think, the most important cause of it is due to the lack of scientific training. And so I observed and analyzed the reasons from the dynamical point of view. When throwing, the laws of Newton 1,2 and 3 should be appljed because the records are different to the throwing angle and speed. From the results of my observation of the relations between the throwing angle and speed, the records were better when the throwing angle was about 38˚ in a low throwing speed and when it was about 42˚ in a high throwing speed. It was abserved that, if the throwing angle leas 45˚, the records were better when it was runing parallel with the throwing angle, but those were worse when it was running down to the ground. One of the causes of bad records, I think, due to the physicil weakness of Orientals. And so I suggest that the field event in olympic games, as far as the shot-put game in particular, should be proceeded under the division of physical grades.

After the sigle anthelmintic treatment aganist Enterobius vermicularis, the egg positive rate returns to pre-treatment level within 20∼30 days. Therefore the antipinworm treatment should be repeated when the endemic enterobiasis is desired to be under control. Recently Hong et al.(1980) proposed a scheme of control in which mebendazole was administered to all residents for 4 times each 20-day interval. By the scheme, the pinworm infection was controlled up to 7 months in low endemic orphanages(mean egg positive rates less than 40%). However, in two highly endemic orphanages(55-70%), the infection was controlled only for 3 months. After then up to 7 months, reinfection occurred, but the egg positive rate was brought down to 20%. To observe the effect of 6-month interval repetition of the above scheme on the control of highly endemic enterobiasis in orphanages, this study was undertaken for one year in the hope of complete control. In three orphanages situated in Anyang City, Kyunggi Do(mean egg positive rates of anal swab being 74%, 80% and 84% in respect), 100㎎ single dose of mebendazole were administered to all orphans and their nursing staffs for 5 tomed each 20-day interval. They were followed up each month by anal swab until 6 months after the beginning of the scheme. The egg positive rates became 0% until 110 days after the institution of the scheme. However, the ratesgradually rused to 3.6%∼12.3%, in all of 3 orphanagesuntil 6 months. Then the second scheme of treatment was tried. Mebendazole was administered for 3 times also each 20-day interval. The egg positive rates again dropped to 0% until 270 days. However, the rates abruptly began to rise to 12.1% on 300 dats, 22.7% on 330 days, 24.8% on 360 days. The rising of egg positive rates was about 40 days after introduction of infected but untreated new-comers to all of 3 subjected orphanages. If the orphanages were the closed society, the hyperendemic enterobiasis would be controlled by repeating the scheme every 6 month. The failure to control the enterbiasis in this observation suggests that the reintroduction of eggs from outside was the main factor of recurring endemicity though the pinworms inside the orphanages were almost completely cleared.

Sports 技術槪念의 現象學的 考察

김성룡,이동현 群山大學校 1997 論文集 Vol.25 No.-

Heutzutage ist allgemein anerkannt, daβ die sportliche Technik in Sportarten einen entscheidend leistungstimmenden Faktor darstellt. Trotzdem ist der Begriff “Technik” im Sport nich immer bis jetzt eindeutif definiert. Der Zweck dieser Betrachtung besteht darin, daβ die Hierarchie der Begriffsbestimm-ung sportlicher Technik durch die phanomenologische Betrachtungweise ins klare gebracht werden soll, um die grundlegende Uberlegung uber die Technik im Sport beizutragen. Beim Zusammenfassen der bisherigen Definitionsvorschlage uber die sportliche Technik kann man sage, daβ der Begriff “Technik”aus den folgenden zwei Komponenten besteht: “Technik als einer bestimmten Sportart”. Im Unterschied zur Technik als Bewegungsfertigkeit versteht man im allgemeinen unter der Technik als Lehrinhalt zuerst ein Grundverfahren zur bestmoglichen Losung einer bestimmten sportmotorischen Handlungabe. Meiste Sportarten setzen sich aus einer Anzahl von Techniken in diesem zusammen, die nicht stereotypische Unveranderlichkeit ausweisen sondern situativ bedingt variiert werden konnen. Sie werden aufgrund einer Gemenisamkeit der raumlichzeirlichen und dynamischen Strukturn in bezug aut Bewegungaform so typisier, daβ der Erwerb dieser Bewegungsform in der Bewegungsschulung erzielt werden. Dabei werden die einzelne konkrete Bewegungsfuhrungsweisen als untergeordenete Techniken hervorgehoben, die das Zustandekommen einer Bewegungsform ermoglichen. Diese Technik als konkrete Bewegungsfuhrungsweise soll auf parktischem Wege gefunden und durch den Transfer einer Bewegungsform auf andere Personen ihre Gultigkeit gepruft werden. Dabei darf man nicht ubersehen, daβ man im phylogenetischen Prozeβ die verschiedenartige Typen innerhalb einer Technik als konkrete Bewegungsfuhrungsweise feststellen konnenn. Infolgedessesen soll es unentbehrlich sein, die grundlegende Techniken zur Hervorbringunf des Grundschemas einer Bewegungsform und die huhere Techniken zum Zustandekommen einer differenzierten Bewegungsrorm zu unterscheiden. Zum Schulβ sei bei der Betrachtung der sportlichen Technik in einzlnen Sportsrt, sorgfaltig solche hierarchische Begriffsbestimmung uberlegr weden soll.

황상일,김혜령,윤순옥 경북대학교 사회과학대학 지리학과 2003 地理學論究 Vol.- No.23

한강하류부에 위치한 김포시 고촌면 김포평야의 충적충과 사면퇴적충에서 퇴적상 분석 및 화분 분석을 실시하여 식생환경, 해면변동, 기후변화와 같은 자연환경인화를 검토하고 이것을 선사시대 인간활동과의 관계에서 살펴보았다. 최종빙기 이래 형성된 연구지역의 퇴적상은 빙기의 선상지성사면퇴적층과 흘로세 충적충으로 구분되며, 화분분석은 흘로세 충적충의 유기질이 다소 포함된 회색실트충, 분해되지 않은 토탄충, 분해된 토탄충에서 이루어졌다. 화분조성은 흘로세 중기 이후 해면미변동을 반영하며, 화분대GP-Ⅰ은 흘로세 해진의 영향으로 수심이 있는 저습지 환경에서 Alnus를 중심으로 한 목본 우점기에 퇴적되었고, 화분대GP-ll시기는 해면의 지속적인 정체와 하강에 따른 지하수위 저하 그리고 활발해진 인간활동의 영향으로 목본이 크게 줄고, 포자와 초본류가 우점하게 되었다. The environmental change such as vegetation environment, sea-level change, climate change and human impact was restored at Gimpo alluvial plain on the upper Han river according to the results of sedimentary facies and pollen analysis. The sedimentary facies which has been constructed since the last glacial stage is composed of the hillslope deposits as the alluvial fan during the glacial stage and Holocene alluvium. Materials for pollen analyses were sampled from gray organic silt layer, peat I layer(abundant fibroid material included the branches of trees and roots of grasses) and peat Ⅱ layer(decomposed peat including organic clay) in the alluvium of the Holocene. The change of the pollen composition reflected sea-level change and vegetation environment during the Holocene. Pollen zone GP-Ⅰ was the period of AP-dominance, including mostly Alnus. Study area was under the lagoon or swamp environment influenced by Flandrian transgression. Pollenzone Ⅱ was the period of Spore & NAP-dominance. It represents that vegetation environment was changed to drier condition by falling the surface of ground-water caused by sea-level regression after long-term stability, and influenced of human activity.

Background : Patients with chronic renal fialure have a substantially elevated risk of death from cardiovascular diseases than do the general population. the patients with chronic renal failure are at significantly increased freqeuncy of hypertension, hyperlipidemia, and diabetes mellitus which are known to the risk factors of the coronary artery diseases, and the prevalence of the coronary artery diseases in chronic renal failure patients is highly associated with the hemodynamic disorder and metabolic abnormalities. therefore we expected that the coronary angiographic findings in patients with chronic renal failure should be different from the general population (control groups) and investigated the risk factors contributing to coronary artery diseases. Method : we have retrospectively compared the coronary angiographic findings of 44 patients with chronic renal failure on hemodialysis with that of 88 patients in the general population and investigated the factors contributing to the development and acceleration of coronary artery diseases in patients with chronic renal failure Result : Hypertension and diabetes mellitus which is risk factors for coronary artery disease is significantly increased in patients with chronic renal failure, in coronary angiographic finding the severity of the lesion is worse. the incidence of PCI or CABG of patients with chronic renal failure is more than that of control group but statistically no difference between patients with chronic renal failure and control group. the sex, the duration of disease, the duration of dialysis, serum creatinine in patients with chronic renal failure have no correlation to the prevalence of coronary artery disease and severity of lesion. hyperglycemic patients with chronic renal failure have high incidence of coronary artery disease and are worse in the severity of lesion Conclusions : There is significantly increased the pevalence and severity of involving multiple coronary artery diseses in hyperglycemic patients with CRF.

The purpose of the study was to investigate relationships among life satisfaction of the elderly women in poor-health conditions, with their self-esteem, health and financial status, family relations, and social participation. A structured questionnaire was used to interview a sample of 168 elderly women who were randomly selected from Sungbuk-ku, Seoul. The statistical methods used were percentiles, means, standard deviations, Cronbach`s α, Pearson`s correlations and a multiple regression. The regression analysis showed that the most powerful predictor of satisfaction of the poor-health elderly women was their self esteem, followed by relationships with their adult children, perceived financial status, age, and the amount of allowances. These variables accounted for 41.7% of life satisfaction of the sample. Implications for the policy-makers and practitioners were further discussed.

1. 單獨處理에 비해 倂合處理가 汚染負荷量으로 볼때 평균 약 31.1%의 더 높은 제거 효율을 얻을 수 있었다. 2. 下水道 流入 BOD 평균농도는 單獨處理時에 BOD 147.5㎎/l~160㎎/l정도인데 비해 倂合處理는 BOD 91㎎/l~100.8㎎/l을 나타내었다. 3. 家庭汚水를 무단방류하는 것보다 倂合處理를 하므로서 水系의 水質改善을 기여하였다. 4. 가능한 淨化槽는 실제 住居人口數보다 容量이 큰 것을 設置토록 하는 것이 좋다. This sutdy was performed in order to evalulate the purification of domestic sewage through single(nightsoil) and combined(nightsoil+domestic sewage) treament. The result of single and combined treatment are as follows: 1. The removal efficiency of BOD loading in Combined treatment was 31.1% more than that of single treatment. 2. The average concentratron of effluent BOD was 147.5㎎/l~160㎎/l in single treatment but 91㎎/l~100.8㎎/l in combined treatment. 3. Combined treatment contributes to improving the quality of water than direct discharging domestic sewage does. 4. It is desirable that, if possible, we should install a bigger septic tank than the volume which the actual residents need.
