The purpose of this study is to grasp the change of consciousness of young people in order to seek new approach of policy for aged era. 1,200 students attending collages and universities in three small or medium sized cities were inquired for 2 months, from October 1 to November 30, 1996. The result is as follows. 1. The characteristic of the respondents of this survey is that they include 72.1% of women, 40.4% of people aged between 20 to 21, and 49.1% of people who do not have any religion. Those who are from big cities and those who are form farming villages or fishing village occupy equally 40.2%, those who reside in that cities for a long period 49.0%, and those who live with their family 60.9%. 2. The family feature of the subject is that 31.5% of them are those whose father is the age of 55 and more than 55, 10% of them are those whose mothers age is so, 33.1% of them have 5 family members, 29.5% of them have the family income of 1,000,000 to 1,490,000 won, 83.9% of them are from middle class, 47.7% of them are the people whose grand parents have passed away, 70.4% of them live apart from their grand parents, and 60.9% of them are second child. 3. 64.0% of males, 70% of respondents who are aged over 24, 58.1% of respondents who are from rural communities, 62.4% of respondents who live in rural area, and 58.3% of respondents who live alone, prefer to live with grand parents, marked higher rate than other groups. The groups whose father and mother are the age of more than 55 marked higher rate of 55.9% and 58% each than any other groups(p<0.05). The groups whose family member is less than three, whose grand parents both have passed away in middle class, who live with their grand parents, and who are second children, give more positive answers than any other groups. 4. Those who are older, who are buddhists, who are from rural area or live in rural area, whose family is small, whose family income is small, who are from lower class and whose grand parents are still alive, shows preference to support their parents after marriage. 5. Females(89.4%), those who are from small or medium sized cities(89%), who live with their family(85.6%), whose father is the age of 55 and more than 55, whose mother is the age of 54 and less than 54, whose family member is 6, who are from middle class, whose grandparents are still alive and who are the eldest child in their family, give more response that they prefer to live apart from their children in their old age than any other groups. 6. What elderly people need most right now is past time(42.3%), and the respondents whose age is 20 to 21, who are buddhists, who are from middle sized cities and live alone, whose parents are the age of more than 55, who have small family income, who live with their grand parents and who are second children show higher level than any other groups. 7. 76.8% of respondents answer that they do not need their parent's fortune, marked still higher rate than the opposite answer. Those who are older, who are buddhists, who are from big cities, who reside in rural area, who live alone and have smaller family, who are in bad family economic conditions and who live with grand parents present higher rate of positive response. 8. 59.3% of respondents reply that they think about death from time to time, and those who are female, who are in the age of 20 to 21, who are christian, who live with their family, whose siblings or other family members offer their education expenses show higher rate than any other groups. 9. 92.3% of respondents answer that the budget for welfare facility for elderly people is very small. The younger the respondents are and the worse economic condition they have among those who live in big cities, the more answered that. 10. 50% of respondents think social security should provide for their old age, and 42.8% of them believe they themselves provide against it. The respondence that social security ought provide for it appeared more among those whose age are over 24, who are female, who reside in rural area, who are christian, who are in bad economic condition, and who ever used medical institutions in recent one month, marked higher level than other groups. 11. The adequate time of retirement is 59.97±5.60 for public officers, the highest and 59.28±6.35 for teachers, the next. 12. 35.2% of respondents reply that the adequate budget for the old age after their retirement at the age of 60 is 220 million won, showed the highest level of respondence. 13. The factors which affect on the old people in the charged welfare facilities are sex(p<0.01), the type of housing(p<0.05) and whole family income(p<0.05). 14. The factors which affect on remarriage are sex(p<0.05) and religion(p<0.05). For varying old population and expanded welfare service for them, government and relevant authority should give more attention to secure the budget, establish effective plans to expand various program and the facilities for elderly people in order that elderly people spend the rest of life time more happily and more fruitfully. To do that, each college and university should open Health courses, and educate and inform about health and welfare.

김병기 崇實大學校 生産技術硏究所 1995 論文集 Vol.25 No.1

There are some ATM switches based on banyan networks with deflection routing and cell extraction. All of them use the same extraction algorithm, which we call linear extraction algorithm. In this paper 2 new algoritms are devised. And a general analytic model is built to evaluate the algorithms. Analysis shows that reverse balancing algorithm is the best and the linear algorithm is the worst.

The effect of dehydrating agent in DMC(dimethyl carbonate) synthesis from methanol and carbon dioxide over Ce_(0.8)Zr_(0.2)O₂ catalyst was studied in this work. Ce_(0.8)Zr_(0.2)O₂ catalyst having the best activity among Ce_(1-x)Zr_(x)O₂ catalysts was selected. We could supposed that the addition of dehydrating agents improved the DMC yield by H₂O elimination. When the dehydrating agents such as Na_(2)SO₄ or K₂SO₄ was added into the synthesis of DMC, the formation amount of DMC increased to about 0.8∼0.9 mmol through the elimination of formed H₂O as by-product.

In order to quantify the characteristics of waterwater, we conducted 8 times of field survey from Oct. 5 to Dec. 10, 2002 for the selected stations of sewage treatment basins at Gapyung-Gun and Yangpyung-Gun. In each survey, we performed 24- ??hr water quality sampling in the interval of 2- ??hr and collected flowdata measured in the interval of 5 to 10 minutes for more than 60 days. From the water-quality analysis, we collected data from various items according to time and station, and stored databases. At this point, effective management and storage techniques of the data are imperative to show information with the location of the sites concerned. Geographic information system is introduced to manage databases and to present the information effectively with graphics. In this study, we constructed a system that could aid ??decesion maker to predict the consequences of various water quality management decesion. The developed wywten could perform a series of these procedures and display the result with map through the computer screen and analyse the current status of environmental quality using ArcView GIS with Excel and Access.

In order to quantify the impact of excess heat discharged from hot spring at Gimcheon on the receiving water, we examined water temperature and its variation representing the state of a water body as a result of heat inputs. To compute the water temperature according to distance downstream, we used a heat balance equation developed by Edinger et. al, assuming the steady state. Under possible circumstances, we made several scenarios according to quantity and temperature of discharged weter, and simulated for the conditions. Based on the results, the impact of scenario 5, which is the best condition for the receiving water, still influences to Gamcheon lake, in which is located 7.5㎞ from the outlet receiving heated water, that will be constructed for preventing flood and providing water resources for adjacent communities.

피조개 발의 조직학적 구조는 hematoxylin-eosin염색 및 Weigert iron hematoxylin염색을, 점액질 성상을 검색하기 위하여 PAS반응, diastase 침지 후 PAS반응, alcian blue pH 2.5염색, alcian blue pH 1.0염색, alcian blue pH 2.5-PAS염색, alcian blue pH 1.0-PAS염색, aldehyde fuchsin pH 1.7-alcian blue pH 2.5염색 및 0.25% toluidine blue염색을 실시하였다. 피조개의 발은 상피, 상피하결합조직 및 근층으로 이루어져 있었으며 상피는 단층섬모원주세포로 되어 있었다. 상피하결합조직 및 근층에 다세포성 점액선인 발선이 발달되어 있었고 도관은 결합조직과 상피세포를 거쳐 개구되어 있었다. 근층은 종주근, 수직근 및 횡근섬유로 구성되어 있었다. 점액질의 조성을 보면 상피세포섬모에는 sialomucin만을, 상피세포는 중성점액질만 함유하고 있었다. 상피세포 및 결합조직내 점액도관에는 산성과 중성점액질의 혼합성인 것과 산성점액질만 함유한 것이 혼재하나 전자가 더 많았다. 산성점액질의 성상으로 보아 대부분이 강 sulfomucin을 가지며 일부는 약 sulfomucin과 sialomucin의 혼합성이었다. 대부분 발선의 점액선포에 대한 점액질 조성은 점액도관과 유사하였으나 일부 상부발선의 점액선포는 중성점액질만을, 하부발선의 점액선포는 sialomucin만을 함유하였다. This study was performed to investigate the histological structure and the histochemical properties of the mucosubstances in the foot of Anadara broughonii. For the histological structure, hematoxylin-eosin and Weigert iron hematoxylin staining were used. The mucosubstances stained with PAS, PAS-diastase, 0.25% toluidine blue, alcian blue pH 2.5, alcian blue pH 1.0, alcian blue pH 2.5-PAS, alcian blue pH 1.0-PAS, aldehyde fuchsin pH 1.7-alcian blue pH 2.5 methods. The foot was composed basically of three layers: epithelium, subepithelial connective tissue and muscular layers. The foot was lined by simple ciliated columnar epithelial cell. Foot glands consisted of multicelluear mucous acini were present in the subepithelial connective tissue and muscular layer. The mucous duct of foot glands was distributed from connective tissue to epithelial cells, and open onto the surface of the foot. The foot muscle traveled in three planes as longitudinal, transverse and vertical muscle fiber. About the properties of mucosubstances on the foot, cilia of epithelial cell contained sialomucin only and epithelial cell neutral mucosubstances only. Most of mucous duct within epithelial cells and connective tissue showed a mixture of acidic and neutral mucosubstances, while a few mucous ducts were contained acidic ones only. Among acidic mucosubstances, notable strong sulfomucin were found in most mucous cell of duct, and a mixture of weak sulfomucin and sialomucin appeared in a few cells. The properties of mucosubstances in the food glands were similiar to those of mucous duct. But a few mucous acini contained neutral mucosubstances and sialomucin only in upper and lower portion of foot gland, respectively.

Bone graft has been used to repair one defect caused by disease and trauma, congenital and acquired deformities. Graft materials are autogenous bone, allogenic bone, xenogenic bone, synthetics. Autogenous bone graft is the most superior to other materials for immunologic reaction, compatibility to host tissue, and revascularization. However, autogenous bone graft is required for additional operation and the amount of taking is limited. Autografts are obtained at own expense and also limited in size, shape. In order to compensate these problems, allogenic bone graft has been used increasingly. But allogenic bone graft encounters immunologic complications. Therefore, it has been used after freezing, lyophilization, or demineralization. Allogenic bone processed by only lyophilization includes potential antigenic properties on its surface, therefore it is demineralized to deplete immunologic reaction. Demineralized bone releases BMP and helps the mesenchymal cells transform to the chondroblast to produce cartilage and bone. This reaction is called osteoinducation. Many authors have reported that mineralized lyophilized bone had less antigenicity clinically and favorable bony consideration with host bone. In our department from 1995 to now, we have used banked allogenic bone graft that has been prepared from Wonkwang Bone Bank in 5 cases and mineralized lyophilized bone graft in 2 cases to reconstruct the maxillofacial bone defect after tumor resection and cyst enucleation and cleft alveolus. We will report with literature review that the result is favorable functionally and esthetically.

This study focuses on the establishment of compulsory license to the patented invention, particularly pharmaceutic patent for public interests. With a view to promoting the development of technology and industry, Patents Act grants patentees an exclusive right to exploit the patented invention. For the purpose of the same goal, on the other hand, Patents Act imposes a few limits upon the exclusive right of patentees. A compulsory license is one of the limits upon patent right. A compulsory license is not an exceptional management from outside, it already exists in the inside of the right in view of the fact that Patent is the right granted artificially to contribute to the development of the industry. Pharmaceutic patent is closely related to human life directly or indirectly. Accordingly it has been discussed internationally to establish compulsory license to pharmaceutic patent for public interests. Regarding this problem, advanced countries and undeveloped countries are at issue with each other. We examine our position about compulsory license to pharmaceutic patent considering the degree of industrial development, especially the reality of pharmaceutic industry where Multinational Corporation of foreign country produces the most medicine. In case of Korea, there is a necessity for compulsory license in wide ranges in comparison with advanced countries such as Canada, Britain, Germany, France and so on within the limits of Agreement on TRIPs. In view of the above statements, it raises several problems of compulsory license under the Patent Act of Korea and proposes their solution. First of all there needs the realistic interpretation of the requirements for public interests and the flexible viewpoint about compulsory license to pharmaceutic patent. It is finally submitted that statutory provisions on compulsory license are designed as an efficient means of promoting goals of the Patents Acts and, also, that terms, conditions and procedures for compulsory license will have to be amended to make a better balance between the interests of patentees and public interest.
