This study was conducted to investigate the effect of homogenized kimchi product (HKP) on dough characteristics and quality of bread. Fermented homogenized Chinese cabbage kimchi product was added 0, 10, 20 and 30% to wheat flour. The pH of dough decreased with an increase in the amounts of HKP. which showed at pH 4.9 for the dough added 30% HKP, Fermentation time of the dough was reduced as much as 9~23 minutes as compared with the control products. Loaf volume index of the bread prepared by adding 10-30% HKP increased also by 12,7~19.0%. Hardness, cohesiveness, springiness and gumminess of the bread added with 30% HKP were lower than those of the control. The gas forming cell of the bread added with 30% HKP were good and regular. Crust and internal color of the bread with more HKP had tendency to redness. Sensory quality of the kimchi-bread estimated by shape, flavor and overall quality was better than that of control product, especially the kimchi-bread quality at addition of 30% HKP was best.

A numerical study has been performed in order to investigate the performance of two different shapes of axial-vane type cyclones. The first is a standard type and the other is the one with a central body of the form of an annular tube. Numerical calculations are made using a well-known Patanker's methodology. That is, a control-volume based finite difference method is employed together with the power-law scheme for the descretization of the convection term appeared in governing equation. The pressure-velocity coupling is resolved by the use of the revised version of SIMPLE, say SIMPLEC. The Reynolds stresses are closed using the standard k-ε model. The general pattern of fluid motion is resolved together with the particle trajectory behavior for 8 different particle sizes as a function of swirl strength and central body. The calculation data are in good agreement with the empirical knowledge, for instance, the effect of swirl intensity. The cyclone with a central body shows a high removal efficiency of particulate but more pressure drop than a standard one. Further discusstions are made in detail.

The purpose of this study was to investigate of the relationship of team effect, empowerment, and leadership behavior of basketball instructors. The subjects of this study were composed of 472(male 350, female 121) basketball players who were selected using the systematic stratification cluster random sampling among the amateur basketball teams in Seoul and Kyung-gi province. The results were collected from a self-administrated questionnaires. It were analyzed through relation analysis, discriminant analysis, ANOVA, and multiple regression analysis. The results of this study were following: First, according to the demographic characteristics of the amateur basketball players, leadership behavior style shows differences. Female player's autocratic behaviors are higher than male player's, and high school player's training & instruction behaviors are higher than middle school player's or university player's. Positive feedback behaviors are getting higher grade level. Player's parents who have athletic experiences are also getting higher grade level. And 2-3 years in career of player's democratic behaviors are the other career of player's. According to the demographic characteristics of the amateur basketball players, empowerment of players shows differences, 100-200 million Won's meaningfulness is the highest among income level in their home, the more 400 million Won's impacts are the highest among income level in their home. And full time player's satisfaction of team effects are higher than the other player's. Second, leadership behavior style effects basketball player's empowerment; it's sub-variances are competence, impact, and self-determination. Social support behavior and positive feedback behavior effect competence and training & instruction, democratic behavior effect self-determination, and positive feedback behavior and social support behavior effect competence. Third, leadership behavior style effects team effectiveness; team effects are discriminated from three group, and democratic behavior and social support behavior effect member satisfaction. Forth, player's empowerment effects team effectiveness; the team effectiveness are discriminated from three groups. The meaningfulness are negative. while the impact is positive in the influences of member satisfaction.

박수언,이동욱,이희성 중앙대학교 의과대학 의과학연구소 1984 中央醫大誌 Vol.9 No.3

The physical properties and the effects of detergent on the activities of purified NAD-linked a-glycerophosphate dehydrogenase(EC 1.1.1.8, GPDH) from kidney, liver and skeletal muscle of the rat were studied. The activity of this enzyme was measured by the method of White and Kaplan. The enzyme activity of liver (9.65 units/g tissue) was higher than those of other organs, but the highest value of the specific activity was shown in skeletal muscle as 0.058 unit/㎎ protein. These enzymes were purified approximately 167, 286 and 216-fold from kidney, liver and skeletal muscle, respectively, by ammonium sulfate saturation and blue dextran Sepharose column chromatography. These enzymes were composed of two isozymes which have different isoelectric points. Isoelectric points of the two isozymes were 6.5 and 6.7, and the molecular weights were 62,000 and 60,000 daltons. The UV spectrums of the purified enzymes from three organs of the rat showed very simillar pattern. But the representative compounds from three classes of detergents showed different effects on these enzymes. The enzyme of the skeletal muscle was activated by all of the detergents which were studied expect for Triton X-100, whereas the enzymes of the kidney and the liver were not activated or strongly inhibited by all of the detergents. In conclusion, the purified a-glycerophosphate dehydrogenases from the three organs of the rat were the homogeneous proteins out of consideration for physical properties. But the differences in the interaction between enzymes and detergents revealed that there are unsimilarities in the three dimentional structure between the skeletal muscle and those of other two organs inspite of similarities between the enzyme of kidney and that of liver.

벼 기계이앙 육묘에 주로 사용하고 있는 플라스틱 육묘상자의 문제점을 개선하고 친환경 농업 실현에도 기여할 수 있는 벼 기계이양 종이 육묘상자개발 및 육묘시험 결과를 요약하면 다음과 같다. 1. 폐지 등 혼합물을 고열압착한 종이 육묘상자는 내부 길이가 가로 58㎝, 세로 28㎝, 높이는 2㎝이고 무게는 250g이다. 2. 종이 육묘상자 모의 파종 후 10일~30일 묘소질은 플라스틱 육묘상자 모에 비하여 초장이 1.1~1.8㎝ 짧고 본당 건물중은 0.3~3.7㎎이 떨어졌으나 엽수와 모 충실도는 비슷하였다. 3. 종이 육묘상자 모의 파종 후 30일(중묘) 이앙 시 결주율은 3.3%로 플라스틱 육묘상자 모 결주율 3.2%와 거의 같았고, 출수기, 벼 생육특성 및 수량도 플라스틱 육묘상자와 비슷하였다. 4. 종이 육묘상자의 이점은 플라스틱 육묘상자에 비하여 육묘상자 비용이 약 20% 절감되고 파종 후 운반, 치상 등 작업이 용이하며, 이앙 후 회수, 세척 및 보관관리 노력이 생략된다. 그리고 이앙 후는 논에서 유기물화되므로 친환경농업에도 부합된다. A light and bio-degradable paper tray for seedling raising in machine transplanting rice was developed for the first time and a possibility for rice seedling growth was evaluated. The paper tray was made of mixture of recycling paper and sawdust, and molded under high temperature and pressure. The tray was 58㎝ length x28㎝ width x2㎝ height in size and 250g in weight per tray. The seedling height and dry weight per plant grown at the paper tray were generally 1.1 to 1.8㎝ shorter and 0.3 to 3.7㎎ lighter than those grown at the conventional plastic tray, respectively. However, other characters such as leaf number, seedling health score, missing hill, heading date, panicle and spiketlet number, and milled rice yield were similar to those in the plastic tray. Based on the result of research, the paper tray had following advantages in comparison of the plastic tray. The paper tray could be reduced seedling raising cost by 20% as compared with the plastic tray. Since the paper tray was of lightness even after seedbed soil fill-up, it was more handy and convenient to carry over. Labor input for collecting, washing, and storing the empty tray after seedling transplanting was not needed as the plastic tray. The paper tray was also bio-degraded and transformed into an organic matter, once it was incorporated into soil, which was considered as an environmentally- safe cultivation technology.

Emphysematous cystitis is an uncommon disease in which bacterias produce gas within the bladder wall and surrounding tissue. Patients with diabetes, neurogenic bladder and chronic urinary tract infection are predisposed to the disease. It is usually caused by E.coli and Klebsiella. Severity of illness ranges from an asymtomatic condition to life threatening cystitis. Succesful management depends on early diagnosis with correction of underlying causes, administration of appropriate antibiotics, establishment of adequate bladder drainage and surgical excision of involved tissue when required. We report a case of 52-year-old woman who did not compain of symtoms of cystitis but epigastric pain, nausea, and vomitting. Emphysematous cystitis was revealed on the abdominal X-ray series incidentally. CT scans of the pelvis showed mottled gas bubble within the bladder. After treatment, the symtoms subsided and plain abdominal film showed no evidence of gas shadow in the pelvic cavity.
