金善應,張仁鉉,許正 慶北大學校 師範大學 1981 體育學會誌 Vol.7 No.-

We obtained the following results derived from the previously described observation and analysis: 1. In the service, the errors by the receive miss and double fault gave greater influence on gain or loss than the gaining points by the ace service. 2. In the practical game, to reduce the losing points by steady placements is more desirable than the strong strokes. 3. The back-hand strokes are the most important in win or loss of game because they attack on the general weak points of the opponent's back-hand strokes in the singles game. 4. The half volley, smash, lob, drop shot and no touch which are known as the offensive plays don't occur many times in a game, So the defensive base line play is usually prefered in the Korean women's single tennis game. 5. The losing points by errors give more influences on the win or loss of the game because no touch play loses more points than the passing shot. 6. In the games of the girl's high school students, the winners gained more points than the lost in the play of volley, passing and lob. The winners of adult women didn't make much mistakes in service, and the similar phenomena was also occured in then fore-hand strokes and back-hand strokes.

Histalog 刺戟에 依한 消化性 潰瘍의 胃液所見에 關한 硏究

兪宣穆,高侊道 우석대학교 의과대학 1971 우석의대잡지 Vol.8 No.1

Among the conventional methods for the study of secretory function of the stomach, the histamine test has been widely used for study of gastric response. Although it is a very useful test, it has some such drawbacks as side action and short acting duration as compared with response to Histalog. Recently Histalog(betazole, Lilly) has been used as a substitute for histamine to produce a gastric response. The author has studied the subjects with peptic ulcer between 1967 and 1968. Peptic ulcers were classified by location in the stomach as follows: lesser curvature(incisura angularis), pyloric region, antrum region and duodenum. Subjects and procedure:- there were 46 subjects(33 men and 13 women): 9 has lesser curvature(incisura angularis), 8 had pylorus, 5 had antrum and 24 were duodenal ulcer. After an over night fast, the stomach was intubated, the residual content was removed, continuous suction was applied manually with a 50㏄ syringe, and secretion collected for three 15 minute periods(basal secretion). Histalog was injected intra-musculary, a dose of 0.5㎎. per kilogram of body weight, and continuous aspirations were made for four additional 15 minute periods. The results obtained were as follows: 1) In patients with gastric ulcer, the mean rate of secretion of free hydrochloric acid varies with the location of the ulcer in the stomach. Ulcers of the lesser curvature of the stomach are observed about twice the normal levels of secretion after the injection of Histalog stimulant(Basal: 13.2±7.02 mEq/45 minut. after the injection of Histalog: 24.13±5.87 mEq/60 minut.), whereas ulcers of the duodenum are observed about three times the normal levels after the injection of Histalog stimulant(Basal: 12.96±6.33 mEq/45 minut., after the injection of Histalog: 36.77±18.63 mEq/60 minut.). But the others were not significantly different. Peptic ulcers were not seen in subjects who did not secrete free acid. 2) The secretory rate of free hydrochloric acid was measured as higher during one hour of secretory response. 3) In patients with gastric ulcer, the mean rate of secretion of pepsin varies with the location of the ulcer in the stomach. Ulcers of the lesser curvature of the stomach are observed about 1.5 times the normal levels of secretion after the injection of Histalog stimulant(Basal 4.17±1.21 P.KU./45 minut. after the injection of Histalog: 5.03±1.45 P.KU./60 minut.) whereas ulcer of the duodenum are observed about twice the normal levels after the injection of Histalog stimulant (Basal: 5.24±2.14 P.KU./45 minut. after the injection of Histalog: 6.24±2.11 P.KU./60 minut.). But the others were not significantly different. 4) The secretory rate of pepsin was measured as higher during one hour of secretory response. The peak of the responses to Histalog was marked significantly between 30 to 75 minutes. 5) Levels of sodium, chloride, and potassium were not significantly different. However, the response of sodium to Histalog was low significantly between 60 and 90 minutes. But the response peaks of chloride and potassium to Histalog were observed significantly between 30 and 75 minutes.

李淳和,金庸桓 嶺南大學校 環境問題硏究所 1994 環境硏究 Vol.13 No.2

호수의 수질을 개선하기 위한 방법으로 강제순환장치를 도입한 인공호 수질의 변화를 검토하였다. 강제순환장치의 도입 전·후 수온의 변화로 비교하여 강제순환에 의한 수질 변화를 예측한 후, 이화학적인 수질의 변화를 검토하였으며, 호수의 수질 변화에 가장 중요인자인 용존산소의 변화를 표면층에서 저니층까지 검토하여 재폭기에 영향을 주는 강제순환의 효과를 제시하였다. 이때 增間댐과 作名댐의 재폭기 계수는 각각 2.612와 2.984g/㎥/day로 나타났다. Limnological survey and several field experiment were done for estimating the effect of artificial circulation. The changes of vertical distribution of dissolved oxygen concentration resulting from artificial circulation were different from the changes of water temperature. The major factors to control the dissolved oxygen concentration under the artificial circulation were suggested to role of reaeration. The reaeration coefficient, R with the artificial circulation for Masuma and Sakuna Dams were estimated about 2.612 and 2.984g/㎥/day, respectively.

이순화 國立 昌原大學校 産業技術硏究所 1992 産技硏論文集 Vol.6 No.-

In generally, water quality of eutrophic zone in lake must decrease nutrients for example phosphorous and nitrogen. This paper is concerned with limnological survey and several field experiment were done for estimating the effect of artificial circulation. Internal nitrogen loading was estimated by the loaboratiory corer method. Sedimentation of nitrogen and suspended solid were determined using sediment traps at bottom. NH₄-N release concentrations of surface on bottom were large more than removed sediment from 5mm to 20mm, However, after cover oxidized sedimentation by artificial circulation decreased NH₄-N release concentration, and nutrients concentrations of interstitical water in sediment were the reverse of the change NH₄-N release concentration by nitrification. TIN release fluxes from sediment lowered from 15.3㎎/㎡/day by 10.7㎎/㎡/day by artificial circulation in Masuma lake.

강둑여과수를 이용한 정수처리 공정별 수질의 변이원성 평가

이순화,박영규,이철희 嶺南大學校 環境問題硏究所 1999 環境硏究 Vol.18 No.2

ABSTRACT Much of the public health concern about this topic originated after the detection of carcinogenic and/or mutagenic compounds in surface water including drinking waters. Such presence of mutagenic substances in river water brings about the possibility of causing hazardous effects on not only aquatic organisms but also human health itself. To secure the safety of drinking water, it should be necessary to monitor these micropollutants. Mutagenicity Test, in this bioassay, should produce at least twice the number of revertants as concurrent negative controls and provide a clear dose-response relationship. In this result, Nakdong River was polluted by the frame-shift mutagenic and hydrophilc compounds. To improve its quality, surface water may be treated in different ways. Several processes, such as bank filtration, coagulation, ozonation and activated carbon adsorption can be used to remove natural and sythetic organic compounds.

「紅樓夢」에 나타난 裝身具연구

張順愛 한양대학교 2004 韓國 生活 科學 硏究 Vol.- No.24

The Purpose of this study was to examine the meanings to symbolize the types and forms of ornaments which were expressed in the mid-eighteenth century novel "Hongloumeng", written by Jo Seul Geun. The meanings of culture and custom were studied on the bases of Manchurian costume which expressed in the novel through the context of contemporary historical characteristics and literary background. The cultural meanings expressed through the ornaments in the novel, were as followed. Hair ornaments were important. The half-shaven and half-braided hair style symbolized the worship of horse mane. Feathers, artificial flowers, and fresh flowers were used as hair adornment. Specially flowers, which decorated the hair, were an old Chinese tradition, expressed the taste and zest of the nature. Manchurian wore three earings. But in the novel "Hongloumeng", only one earing was worn. It definitely was a Chinese(Han race) custom. It was considered that men's costume followed after Manchurian but women's costume followed after Chinese(Han race) in those days. In those days, foot-binding was in fashion. But in the novel, men and women wore all "Hwa"(shoes) which showed the lifestyle of horse-riding Manchurian. In "Hongloumeng", a small knife and Hapo(purse) were also described, which reflected the social manners of the nomadic life in those days. Also Hapo(purse), embroidered or decorated with patterns symbolizing love, was used as a pledge of love. Neck was decorated with necklace, sable fur, and purple silk scarf which gave warmth and showed richness. A life charm was a symbol of prayer which showed the social influence of "arts and sciences movement" during Qing dynasty. The result of this study was that the Manchurian and the Chinese(Han race), had different alien costume culture, made the unique costume culture during Qing dynasty through contacts and interchange.

아도르노의 『부정변증법』과 철학의 종언 : 독일 철학적 미학의 새로운 지평 미학의 전제로서의 철학

이순예 한국미학회 2003 美學 Vol.35 No.-

Wir leben im Zeitalter der sog. Mediengesellschaft Diese Gesellschaft lasst sich vor allem durch das Verschwinden der Materie im kognitiven Umfeld charakterisieren. Traditionell be schaftigt sich die deutshce Philosophische Asthetik mit dem Eigensinn des Scheins. A domos Negative Dialetik eroffnet eine neue Ara dieser Tradition, indem sie das Ende der Philosophie Proklamiert. Nach Adomo ist philosophie nicht mehr fahig, die Wahrheit herbeizufuhren, weil die Materie dem kognitiven Netz entgeht. Er verleiht dem schein die utopieverweisende Funktion, die von den burgerlich en Verhaltnissen verbannts Materie wieder in unser Bewusstseing hervorzuh olen. Der Schein, welcher die ideelle Materialitat einleitet, soll die Wahrheit in der entzweiten Welt beruhren. Kunst wird zum Statthalter der Wahrheit.

인공호수 저니로부터 영양염 용출변화에 관한 연구

이순화,김용환 嶺南大學校 環境問題硏究所 1996 環境硏究 Vol.15 No.2

호수내에 있어서 영양염의 변화에 미치는 영향을 고찰하기 위하여 저니에서의 영양염의 용출영향을 보면, 수온에 따른 저니에서의 영양염 용출실험의 결과, 혐기성 상태에서 영양염 용출은 10℃, 20℃, 30℃로 변화 시켰을때, TIN은 2.70, 3.31, 3.78 g/㎡/d로 각각 용출되었고, T-P의 용출량은 0.61, 0.74, 0.76 g/㎡/d였으며, 수온이 높을수록 용출량이 높게 나타나 온도의 의존성이 있다고 판단된다. pH에 따른 저니에서의 영양염 용출실험을 한 결과, 혐기성 상태조건에서 PO_4-P의 용출은 pH가 높을수록 비례적으로 용출량이 많았으나 TIN의 경우는 pH의 의존성이 인의 경우보다 낮게 나타났다. DO에 따른 용출량 변화는, 호기계에서 보다 혐기계인 상태에서 용출이 많이 일어나고 있으며, 호기계에서 용출이 적은 이유는 DO가 저층에 있는 저니에서의 영양염 용출이 일어나는 것을 억제했기 때문이라고 판단된다. This Study focuses on the nutrient release in the artificial lake sediment. Results show that TIN release rates were 2.70, 3.31, 3.78 g /㎡/d, and those of T-P were 0.61, 0.71, 0.76 g/㎡/d at the 10℃, 20℃, 30℃, respectively, indicating the effects of temperature on nutrient release in the sediments. It can also be shown from the experimental result that the release rate PO_4-P increases with increasing pH while that of TIN is not so much affected by the pH, and the nutrient release is more active in anaerobic condition than in aerobic condition Indicating that DO suppresses the nutrient release in the lake sediments.
