본 연구는 집성 염색 무니목 개발을 위하여 사용 가능한 수종과 3종류의 염료를 사용하여 염색시간, 염색온도, 함수율 및 Flitch 제작에 대하여 연구한 결과는 다음과 같다. 실험에 사용한 4수종 중에서 선삭성이 불량한 은수원 사시나무를 제외한 3수종인 소나무와 이태리 포플러, 마티카가 사용 가능한 수종으로 밝혀졌다. Stain은 번지거나 얼룩이 지는 현상, Dylon은 침투 불균일로 부적당하였으나 Fine은 염색상태가 양호하였다. 염색시간은 5시간 이상 되어야 염색정도가 양호하였고, 염색온도는 90℃에서 가장 적당하였으며 생재와 기건재 및 포수재에 대한 영향은 큰 차이가 없었다. Flitch제작에 적당한 함수율은 9%이었다. This study was carried out to develop laminated dyeing wood, for which usable three sixties of trees and 3 kinds of dye stuffs were used to investigate dyeing time, dyeing temperature, moisture content and manufacture of flitch, the results were as follows: Out of four species of trees used in the experiment, it was found that three species, Pinus densiflora, Populus euramercana and Dyrea costulata were usable excluding Populus tomentiglandulosa whose cutting ability was bad. As to influence according to the kind of dye stuff, the Stain of low price could be used as a coloring agent but it was not proper as a dyeing agent due to spreading or staining phenomenon. As Dylon which was generally used to dye textile penetrated them uneven, dyeing only their surface, it was also found improper to be used. On the other hand, the dyed condition was good with Fine. The dyed condition was good when dyeing time was more than 5 hours and it was the most adequate when the temperature was at 90℃. There was no significant difference between their influence on green, dried and saturated wood.-In the manufacture of Flitch, the most appropriate moisture content was 9%.

本 實驗은 杭의 직경을 변화시킨 경우 短杭의 引拔低抗力 實驗的으로 考察했다. 다음은 杭基礎의 引拔低抗力 實驗을 행한 결과를 요약한 것이다. 引拔低抗力과 變位量과의 關係에 있어서 地盤의 다짐정도에 따라 전체적 경향이 다르게 나타났다. 이는 전단대발생 Pattern의 차이가 원인인 것으로 생각할 수 있었지만 여기에 대한 상세한 것은 금후 발표할 예정이다. 그리고 地盤의 다짐정도가 클수록 限界 引拔低抗力은 根入深에 대해서 一次函數的으로 증가했지만 杭의 직경이 클수록 감소했다. 이는 杭의 Scale effect가 원인인 것으로 생각할 수 있지만 금후 상세한 검토를 행할 필요가 있다. 本 實驗에 있어서는 杭의 直徑 43㎜경우를 제외하면 Loose sand상태에 대해서만 實驗을 행하고 지금까지 연구발표된 결과를 토대로 고찰을 행했지만 금후 Dense sand 상태에서의 실험도 행할 필요가 있다. 또 실제 전단대발생에 의한 진행성파괴에 대해서 상세히 고찰할 필요가 있다. The uplift capacity and the scale effect of short piles are important to the rational design of pile foundation. Therefore, this paper discribes the results of an experimental consideration on the uplift capacity and scale effect of short pile. The Pile used in the pull-out test is the cylindrical concrete piles. Pile diameter is 43㎜, 66㎜ and 83㎜. The pile length of embedment is 20㎝~40㎝. Pull-out tests were carried out using sand have two densities : loose these results, the following conclusions were obtained : The rate of increase in ultimate uplift capacity become larger due to the increase in the pile length of the embedment and the unit weight of sand. The larger the pile diameter is, the larger ultimate uplift capacity increases. The larger the pile diameter is, the smaller ultimate uplift capacity per unit area decreases.

生命保險契約上 約款貸付의 法的性質

李炯根 건국대학교 1995 대학원 학술논문집 Vol.42 No.-

The policy loan in the life insurance contract is a valuable provision enabling a policyholder to draw upon cash values to meet temporary financial problems without resulting in policy surren-der and loss of the insurance. And through the use of this provision, a policyholder can guarantee the pdicy against lapse in the event of premium default if the loan value is sufficient to pay the premium. However the loan is not a legal obligation of the estate. Courts have held that a policy load is not a tme loan but an advance payment of funds which are, or will be, payable under the policy either as cash values, matured endowmentsi or death benefits. The insured's estate, therefore, is not liable for unpaid policy loan, but the insurer will deduct any unpaid balance from the policy procedds. PoUcyhlders who take policy loan are not borrowing their own money, but money belonging to all policyholders as a group witch must be invested in order to support the insurefs premium structure. Therefore, insurers charge interest on the policyholders' money. In now a days, with the development capitalistic economic system and society, in connection with the policy loan the conflict will occur between the insuFer and the policyholder as premium becomes large and insurancemoney become large amount in future. That is, the legal character Accordingly the study to resolve the problem is necessary as well. It is hope that this study may be helpflll to interpretaion and development for theory on legal character of policy load in life insurance in our country.

Coicis Semen is one of the oriental medicine that has been used for the treatment of the disease such as pulmonary abscess, periappendicular abscess and wart since ancient times. However, the mechanism of the action of the drug is not well studied. This study was done to investigate the effects of Coicis Semen on the host defense mechanism. Effects of Coicis Semen on the immune responses were analyzed by measuring the contact gypersensitivity, hemagglutinin, hemolysin and rosette formation, cytotoxicity, and reactive oxygen intermidiates production. As the results, water extract of Coicis Semen administration enhanced the antibodies (hemagglutinin and hemolysin) formation and the appearance of rosette forming cells of the spleen. Also Coicis Semen increased the allogeneic immune response in the mouse, showed cytotoxic activity against human leukemia cell line(K562) and decreased the contact hypersensitivity against dinitroflurobenzene. Also administration of Coicis Semen slightly increased NK cell activity and enhanced the production of such reactive oxygen intermidiates as superoxide and hydrogen peroxide from the macrophages in vivo and in vitro. The above results demonstrate that Coicis Semen has enhancing effects on cellular and humoral immune responses against disease.

Background : Dental hygienists are at risk of acquiring infections through exposure to infectious agents. This study explores the frequency of exposure to infectious agents and infection control practices among dental hygienists. Methods : We undertook a cross-sectional survey to examine the exposure to infectious agents and infection control practices among dental hygienists through questionnaire. Data were obtained from 124 dental hygienists attending educational conferences. A multiple logistic regression analysis was conducted to determine the factors that effect infection control practices in to age, completion of infection control education, recognition of their own serum hepatitis Ag/Ab status, the number of one day patients, location of clinics, type of clinics, and career years. Results : Of the 124 dental hygienists, 91.7% were exposed to at least one accident such as needle strike injuries during their practices periods. The health screening coverage rate in dental hygienists was 16.5%. The number of one day patients and career years were important in relation to infection control practices among dental hygienists. The adjusted odds ratio estimates for career years were 5.049 times greater(95% CI 1.238-20.597)for groups with 4 career years than under 2 career years. That for the number of one day patients were 0.261(95% CI 0.071-0.0955)lower for through 20 up to 30 patients, 0.531(95% CI 0.102-2.78)lower for through 30 up to 40 patients and 0.498(95% CI 0.123-2.017)lower for more than 40 patients than under 20 patients. Conclusion : From these results, prevalence of infection control practices among dental hygienists is related to the number of one day patients and career years. Prevention of cross infection and reduction of future transmission should be a priority to dental hygienists for promotion of infection control and further efforts to educate newcomers on infection prevention should be made.

Objective : The aim of this study were to measure quality of life(QOL) in liver transplant recipicnts, to ocmpare QOL between living donor liver transplant recipicnts and cadavcric live transplant recipients and to investgatre whether SF-36 may be used as a disease-specific instrument in liver transplant recipients. Methods : We conducted a single-center cross-sectional study of 133 LT recipients ages 13 to 65 years, all of whom had had Liver Transplantion(LT) at least 1 months previously. QOL was assessed using a self-completion questionnaire consisting of the Bang Whal Ran(1991) instruments and the 36-Item Short-Firm Health Survey(SF-36) health status profile measure. We investigated whether the SF-36 instrument may be used as a disease-specific instrument in LT recipients. Individual scale scores range from 0 to 100 , with higher score reflecting better health. Data on demograpics, clinical status at pre transplantation 1 day, post transplantation clinical statns, and graft gunction were collected to identify predictors of post transplantation QOL. Results : Standard measures for test-rtest reliability, internal consistency, and discriminant and concurrent validity were examined. The reliability of the SF-36, as measured by test-retest correlation(Pearson coeffocoents: 0.729, p=0.002) and by internal consistency (Cronbach's alpha: 0.9431) exceeded conbentional acceptability criteria. The correlation between domain scores of SF-36 and the Bang Whal Ran(1991) was clear and logical in that the clinical characteristics of SF-36 strongly correlated with the clinical component summary score of the Bang Whal Ran(1991)(r = 0.8155, P<01). SF-36 scale scores were compared between Cadaveric Liver Transplant recipients and Living Donor Liver Transplant recipients. Donor types of post LT did not influence HRQOL(P >0.05). 87% of the liver transplant recipients were safisfied to get LT. Satisfaction of post LT showed significantly greater HRQOL(p<0.001). Conclusion : SF-36 is found reliable and valid. This study indicates thet Donor Type did not influence HRQOL after LT. The information gained from this study will help us to better define expectations and the colinical course after liver transplantation to patients and their families.
