張瑞鎭 호남대학교 1990 호남대학교 학술논문집 Vol.11 No.2

The purpose of this study is to analyze the differences of locus of control athletes according to their Sex and individual or group entris. The major findings of this study are as follows : ㆍWhen they wins 1. The male athletes have inclination of the interval attribution, and especially they think that the winning result from effort. 2. The female athletes have inclination of the interval attribution, but they under estimate the influence of their abilties. 3. The athlete on occations of indivicual entries have inclination of the interval attribution, and they have the strong faile that the winning is result from effort, but ability. 4. The athlete on occation of group entries have inclination of the interval attribution, and they conceive that the winning is influenced by effort. ㆍWhen they less 1. The male athlete have the inclination of interval and attribution, but more interval attribution. 2. The female athlete have the inclination of the interval attribution. 3. The athlete on occation of individual entries have inclination of the interval attribution. 4. The athlete on occations of group entries have inclination of the interval attribution, and they conceive that the loss result from their inabilities and their rirals' strgng power.

배드민턴 運動이 健康에 미치는 影響

張瑞鎭 호남대학교 1993 호남대학교 학술논문집 Vol.14 No.-

This Study is to make aneestimation of the effect of Badminton exercises on on the improvement of health of 250 club members hwo are practising exercises regulacly. 1) About the half of the pollee anewered that they had Started to play badminton from the motives of improving their health, which shows that the problem of the lack of exercises is going of bring about the serious health Unbalance in modern society. 2) About 6 or so of pollee answered that they were playing Badminton five or six times a week and 29.2% of than used to play badminton for about an hour, 25.6% about 50minutes and and20.0% about 70minutes which shows that to play badmintion as the club exercises for about an how every day is abequate for improving health. 3) Before their badminton practices, a total of about 90% of pollees felt that they had hard time in their body movements deriving from ailments or bad physical conditions such as mental stress, lumbago, chronic fatigue and circulatory diseases. But The percent dropped to nearly 40% by solving the problem of the lack of exercise through badminton playing. 4) While 12.6% answered that they had been Weak before the badminton exercise, only 1.3% said they are in infirmity after. The fact shows badmintor practice has a great effect on the improvement of physical conditions. 5) On the ailment prevention after starting the practice, 92.4% of pollees said they experienced the effect contrary to 7.6% no experiences and by playing badminton periodically, the conflict among family reduced 92% to 41.6%. 6) On the phenomenon of lack of exercise before the launching of badninton practice, 98% experienced the phenomenon. But 99.6% went through the impact of badminton exercise later. This leads to a conclusion that in fact psychological phenomenon played a great role in influence on working out the lack of exercise.

Tenax-GC를 利用한 大豆乳와 醱酵大豆乳의 風味成分 分析

愼重燁,李瑞九,金顯五,朴啓仁 경희대학교 부설 식량자원개발연구소 1987 硏究論文集 Vol.8 No.-

Soy milk prepared from soy protein isolate and soy milk fermented with Lactobacillus acidophilus were adsorbed and desorbed by using Tenax-GC method and analyzed by Gas Chromatograph. It was found that this techingue was very efficient when the analytical results was expressed by the ratis of the peak area of each volatile to that of a fixed concentration of internal standard. Acetaldehyde, ethyl vinyl ketone, n-hexanal, n-hexanol, and 1 -octen-3-ol existed in soy milk. The content of acetaldehyde and diacetyl was increased while that of n-hexanal was reduced by lactic fermentation.

Effect of Deformable Filler Formed by Hydrolysis of Silane Compounds

Sur,Gil Soo 嶺南大學校 工業技術硏究所 1987 연구보고 Vol.15 No.2

사전 경화된 탄성체내에 silica filler를 침전시켜 탄성제를 보강시키는 종전에 개발된 방법을 확장하여 curing 과 filling을 동시에 가능하게 하고자 하는 것이 본 연구의 목적이다. 즉, 과량의 phenyltriethoxysilane과 vinyltriethoxysilane 혼합물을 hydroxyl-terminated poly(dimethylsiloxane)과 반응 시킴으로서, 여분의 silane 혼합물은 가수분해하여 미세한 filler가 성성되었다. Deformable filler가 poly(dimethylsiloxane) network에 존재하므로서, upturns 하는 데 필요한 신도가 줄어들었으며, network의 ultimate strength와 network을 파괴시키는데 필요한 energy는 증가하였다. A method developed previously for the precipitation of reinforcing silica filler within an alredy cured elatomer is extended to the permission of simultaneous curing and filling. Specifically, mixtures of phenyltriethoxysilane and vinyltriethoxysilane were used to link hydroxyl-terminated chains of poly(dimethylsiloxane), with the excess present being hydrolyed to finely divided deformable filler particle. The present of deformable filler in polydimethylsiloxane networks cause the decrease of the elongation required upturns in modulus and increase of the ultimate strength and energy required for rupture of the network.

Phytoceramide Alleviates the Carrageenan/Kaolin-Induced Arthritic Symptoms by Modulation of Inflammation

Sur Bongjun,Kim Mijin,Villa Thea,Oh Seikwan 한국응용약물학회 2023 Biomolecules & Therapeutics(구 응용약물학회지) Vol.31 No.5

Phytoceramide (Pcer) is found mainly in plants and yeast. It can be neuroprotective and immunostimulatory on various cell types. In this study, the therapeutic effect of Pcer was explored using the carrageenan/kaolin (C/K)-induced arthritis rat model and fibroblast-like synoviocytes (FLS). Pcer treatment (1, 10, and 30 mg/kg/day) were given to the arthritic rats for 6 days after disease induction. Weight distribution ration (WDR), knee thickness, squeaking score, serum levels of proinflammatory mediators, and histological analysis were measured and performed to evaluate arthritic symptoms in the rat model. In interleukin (IL)‑1β‑stimulated FLS, proinflammatory mediators were measured after Pcer (1-30 μM) treatment. Arthritic symptoms in rats with Pcer treatment were significantly decreased at days 4 to 6 after C/K arthritis induction. Inflammation in the knee joints were also significantly decreased in rats with Pcer treatment. Furthermore, in IL-1β‑stimulated FLS, the expressions of proinflammatory mediators were also inhibited by Pcer. As shown by the results, Pcer has anti-arthritic effects in the C/K rat model and in synovial cells, suggesting that Pcer has the potential to be a useful agent in arthritis treatment.

AN INTEGRAL EQUATION FOR KINKED CRACKS APPLIED TO MODE Ⅲ IN FINITE PLANE BODIES

Sur, Ukhwan 한국산업정보응용수학회 1998 한국산업정보응용수학회 Vol.2 No.1

An integral equation representation of cracks was presented, which differs from well-known "dislocation layer" representation. In this new representation, an integral equation representation of cracks was developed and coupled to the direct boundary-element method for treatment of cracks in plane finite bodies. The method was developed for in-plane( modes I and 11) loadings only. In this paper, the method is formulated and applied to mode I11 problems involving smooth or kinked cracks in finite region. 'The results are compared to exact solutions where available and the method is shown to be very accurate despite of its simplicity.

Synthesis and LCST Behavior of Thermosensitive Poly (N-isopropylacrylamide)-Clay Nanocomposites

Sur, Gilsoo,Lyu, Sung-Gyu,Chang, Jin-Hae 한국공업화학회 2003 Journal of Industrial and Engineering Chemistry Vol.9 No.1

Thermosensitive polymer-clay nanocomposites were prepared via organically modified clay-poly(N-isopropylacrylamide) (PNIPAM) nanocomposites. Nanocomposites containing a 5 wt% montmorillonite exhibited a lower critical solution temperature (LCST) similar to the unmodifed PNIPAM hydrogel, and similar phenomena with a large thermal volumetric change and transition kinetics compared to conventional PNIPAM gels. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) suggested that the clay minerals in the nanocomposite were partially exfoliated in a dried state and mostly exfoliated in a swollen state.

Development of a Numerical Methodology for Analysis and Design of Weldments

Sur, Ukhwan The Korean Society of Mechanical Engineers 2001 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.15 No.4

There are many analysis formulas for determining the resultant shear force in welds. However, there is no general procedure which is applicable to a joint with all six possible loadings exerted simultaneously. A numerical methodology and computer program for such a problem were developed, and they are capable of analyzing a weld of any shape composed of straight or circular line segments. The computer program developed in this study can also display the design procedures and results using computer graphics. The development of such a design procedure and an interactive computer program for weldments analysis will lead to lower cost.
