To evaluate the hemolytic activity of T. vagindlis from Korean women and fresh human RBC of A type were nsed for hemolytic assay. RBC(1×10 /ml) was added to RPMI-TPS media(RPMI 1840:TPS-1= 20 : 1) containing T. vaginalis(2×10 ) and incubated at 37℃, 5% CO₂incubator for 6hr and hemolysis was measured by spectrophotometer at 412m. We investigated the parasite to erythrocyte ratio and lemperature needed for hemotysis. Optimal erythrocyte lysis by T. vaginalis was achieved at ratio of 1 : 5 and optimol temperature 37℃. Minimal hemolytic activity was detected in lysates of T. vaginalis. No hemolysis occured when a membrane a 3㎛ pore size was nsed to prevent contact between parasites and erythrocytes. These data suggest a need for contact for trichomonol hemolysis. Hemolytic activity did not correlated with the production of subcutaneous abscess in mice.

The purpose of this study was to find the way of treatment and prevention the stroke by Sangsang constitutional medical therapy. I came to get some conclusions after considering literatures of 《Dongyi Suse Bowon》and the conclusions as follows. 1. In 《Dongyi Suse Bowon》the stroke of Soumin is caused by 'Interior cold disease'. When 'Interior Yin' can not descend, the disease arise. In this case Lee Je-ma used 'Sohabhyang-won(蘇合香元)' , 'Chulaek-su(鐵液水)' . 2. The stroke of Soyangin is caused by 'Interior heat disease'. When the hot Qi of stomach and spleen is blocked, the disease arise. In this case Lee Je-ma used 'Dokhwal-jihwang-tang(獨活地黃湯)' , 'Jihwang-baekho-tang(地黃白虎湯)'. 3. The stroke of Taeumin is caused by 'Dry and heat disease'. When the heat of liver and the dryness of lung is excessive, the disease arise. In this case Lee Je-ma treated with 'Woohwang-chungsim-hwan(牛黃淸心丸)'. 'Wonji-sukchangpo-tang(遠志石菖浦湯)' , and 'Kwache-san(瓜帝散)' etc. Above results indicate that not only taking medicine but also filling up the Healthy energy(保命之王) is important to treat stroke.

Reproductive cycle and sex reversal of Pseudolabrus japonicu s were investigated histologically on the gonadal development, sex change of the gonad and studied by gonadosomatic index(GS1). color patterns. Sample were collected at the costal area of Ham duck in Cheju-do. from December, 1990 to November 1992. In male and female, GSI began to increase from August and reached it's malimum value in October, respectively. It began to decrease from December, the low temperature season, thereafter, maintained relatively low values until July of next year. The annual reproductive cycle of this species could be classified into four sucessive developmental stage : growing stage (August-September), mature stage (September-October), ripe and spent stage (October-December), degenerative and resting stage (December-July). The species is a diandric, protogynous hermaphrodite. and has two color patterns : red-yellow (A) and dark-green (B). A-fish were less than 14.5cm SL and consisted of females (92.7%), secondary males (3.6%), and fish with transitional gonad (3.6%). B-fish consited of secondary male (80.2%). primary male (5.5%). female (5.5%) and fish with transitional gonad (8.8%). In P.japonicus, individuals with hermaphrodic gonad were observed in 11.5-16.0 cm SL. Sex reversal of this species could be occured from 11.5 to 16.0cm SL.

The purpose of this study was to evaluate positioning of the brand image in travel industry. To achieve the purpose of this study, theoretical and empirical study was used. In review of theoretical background, basic concepts and strategy of brand image positioning were studied. Based on the theoretical studies and previous studies, brand image attributes were chosen. An empirical study was conducted with cases of Hana Tour, Freedom Travel Service, Mode Tour, High-Sense Travel Service, Lotte Tour, Hanjin Travel Service. And a list of questions in five categories-brand similarity, perception for attributes, brand image preference, importance for attributes, and personal characteristics of respondents-were constructed and tested. In this research 8 brand images attributes was discussed, they are easiness of remember, easiness of pronunciation, familiarity of brand, good thoughts of brand, freshness(newness) of brand, speciality(originality) of brand, an attribute in connection with product price, an attribute in connection with product quality. The ultimate objectives of this study is to suggest the effective direction to set up a brand positioning strategy by using brand images. But this study had limits on sampling was extracted six travel agencies because of time limitation. Therefore, the more systematic and continuos study should be executed to overcome those kind of limits.

윤정로,심재익,김택선,이성종,김영배,김학준,안국환,장재영,홍명표 대한골절학회 2002 대한골절학회지 Vol.15 No.4

쇄골 중간 1/3 부위의 골절은 치료 결과가 양호하여 보존적 치료가 원칙적으로 받아 들어지고 잇으며 불유합에 대한 빈도도 낮은 것으로 되어 있다. 그러나 최근 전위 및 단축의 정도가 심할 경우 높은 불유합의 결과와 불량한 임상 결과를 보고하고 있어 이런 예에 대해선 수술적 치료를 권장하고 있다. 저자들은 단축 및 전위의 정도와 불유합의 연관성을 알아보고자 하였다. 연구 대상 및 방법 : 1993년 2월부터 2002년 1월까지 본원에 내원 했던 성인 중간부 쇄골 골절 환자 194명 중 완전 전위를 보인 78례를 조사하여 이중 63례를 대상으로 분석하여 후 향적 연구를 시행하였다. 4개월 추시 후에도 방사성 사진상 유합 소견이 관찰되지 않으면 불유합의 유의성을 알아보고자 하였다. 결 과 : 63례 중 불유합 및 지연 유합을 소견을 보인 환자는 15(23%)례였다. 골유합을 보인 48례의 단축은 평균 8.6㎜(2㎜-17㎜)였고, 전위는 평균 9.7㎜(2-22㎜)였다 .불유합 및 지연 유합을 보였던 15례에서 단축은 평균 14.5㎜(3㎜-37㎜), 전위는 평균 17.3㎜(4-25㎜)였다. 18㎜이상 단축이 있었던 경우 불유합의 발생과는 통계학적으로 유의성을 나타내었고(Fisher's exact test, p<0.01), Chi-square test상 16㎜ 이상의 전위를 보였던 경우 불유합 발생과 통계학적으로 의미가 있었다(p<0.01). 결 론 : 쇄골 골절 특히 중간 1/3의 골절은 비교적 보존적 치료에 결과가 좋은 것으로 되어 있으나, 전위 및 단축이 심한 경우 불유합에 대한 가능성이 높이 때문에 보다 경과 관찰시 유합의 진행이 없으면 적극적인 치료를 고려해야한다. Purpose : Because the prognosis of the mid 1.3 clavicle fracture is good, the conservative treatment with a figure of 8 bandage is the gold standard and the nonunions are rare. However, recently surgical treatment is recommended when the shortening and displacement is severe because of the high nonunion rate and the poor clinical result. This study was undertaken to evaluate that the shortening and displacement at fracture site are associated with the development of nonunion. Materials and Methods : We analysed the 194 fractures of mid 1/3 clavicle in adults which had been treated conservatively from February 1993 to January 2002 and did the retrospective study. Of these, 78 cases were originally in the middle third of the clavicle and had been completely displaced. We reviewed 63 of these cases. The shortening and displacement at the fracture site was measured on the initial roentgenogram. And the analysis of the patients' chart was done for another predisposing nonunion factors. Nonunion and delayed union are considered to be present when there has been little or no progression of clinical or radiographic healing at a minimum of 4 months after injury. Results : 15 of the 63 cases had developed nonunion.. The average 8.6㎜(2㎜-17㎜) shortening and average 9.7㎜(2-22㎜) in the union patients. The average 14.5㎜(3㎜-37㎜) shortening and average 17.3㎜(4-25㎜) in the nonunion patients. We found that initial shortening ≥18㎜(Fisher's exact test, p<0.01) and initial displacement ≥ 16㎜(Chi-square test. p<0.01)at the fracture site were significantly associated with the development of nonunion. Conclusion : The conservative treatment with figure-80-bandage is the gold standard in the clavicle middle one third fracture. However, the nonunion is commonly occurs in the cases of more of severely shortened and displaced fractures. If there are no signs of callus formation and the patient complains of pain after several week, osteosynthesis should be considered.

Objective : This study was performed to investigate the relationship between social support and quality of life among cancer patients receiving radiation therapy. Matehals and Methods : The data were collected from 98 patients, who were receiving radiation therapy at two university hospitals located in GwangUJu, used by structured questionnaire. For statistical analyses of the association between quality of life and various characteristics, data were analyzed using t-test, ANOVA, Pearson 's correlation, and multiple regression analysis. Results: 1. There were 56(57.1%) males and 42(42.9%) females. Age ranged from 21 to 82 years. The primary sites of cancer were gastrointestinal tract (24.5%), lung (23.5%), breast (21.4%), and head and neck (11.2%) in order. 2. The mean scores of social, family, and medical support were 4.30 0.58, 4.49 0.78, 4.11 0.65, respectively. The score of quality of life was 5.83 1.63 (range: 1.95 ~ 9.05). 3. An analysis of the association between several factors of patients and quality of life showed that the statistically significant factors were age, the presence of distant metastasis, family support, medical support and social support. 4. As a result of the multiple regression analysis, only social support was significant (β=0.932, P=0.02) with quality of life, but age and presence of distant metastasis were not significant. Conclusion : This suggests that quality of life in cancer patients could be improved by strengthening the social support which consists of family and medical support. Further study would be necessary to evaluate separately several aspects of quality of life among cancer patients.

Ahn, Taek The Korean Institute of Electrical and Electronic 2012 Transactions on Electrical and Electronic Material Vol.13 No.6

Poly[4,4'(3,3')-biphenylenevinylene-alt-2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylene-vinylene], 4,4'(3,3')-PBPMEH-PPV, and poly[4,4'(3,3')-biphenylenevinylene-alt-N-ethylhexyl-3,6-carbazolevinylene], 4,4'(3,3')-PBPCAR-PPV, of varying effective conjugation lengths, were synthesized by the well-known Wittig condensation polymerization between the appropriate biphenyl diphosphonium salts and dialdehyde monomers such as carbazole or dialkoxyphenyl dialdehyde. The conjugation lengths of the polymers were controlled by biphenyl linkages (4,4' or 3,3'). The resulting polymers were highly soluble in common organic solvents and exhibited good thermal stability up to $300^{\circ}C$. The synthesized polymers showed UV-visible absorbance and photoluminescence (PL) in the ranges of 314-400 nm and 430-507 nm, respectively. Carbazole and 3,3'-biphenyl containing 3,3'-PBPCAR-PPV showed a blue PL peak at 430 nm. A single-layer light-emitting diode was fabricated in a configuration of ITO/polymer/Al. Electroluminescence (EL) emission of 3,3'-PBPCAR-PPV was shown at 455 nm.
