姜正模,朴勝祿 한국국제경제학회 2004 국제경제연구 Vol.10 No.3

본 연구에서는 2,223개 한국기업들을 공기업, 민간기업, 재벌기업, 비재벌기업의 기업형태 별로 구분하여 외환위기 이후 구조조정 성과를 평가하고 있다. 노동생산성, 자본생산성 및 기술적 효율성 수준뿐만 아니라 총요소생산성 증가율을 기술변화율, 규모의 경제효과, 기술적 효율성 증가율로 구분하여 동태적 측면의 생산성 변화추세를 비교하였다. 주요 결론은 외환위기에 대한 기업의 대응이 인력감축, 자산매각으로 인한 요소생산성의 개선이란 외형적 효과에만 치중하였을 뿐 총요소생산성을 크게 개선시키지 못하였고, 특히 기술혁신과 효율성 수준을 획기적으로 개선시키지 못하여 기업의 성장잠재력 개선에는 큰 성과를 이루지 못했다는 점이다. This study examines the economic performance of restructuring for 2,223 Korean firms which are classified into public firms, jaebol and non-jaebol firms during the period of 1995-2002. We analysed the trend in labor and capital productivity, technical efficiency, and total factor productivity. The translog functional form of the stochastic frontier production function to measure the TFP decomposed into technical change, technical efficiency and economies of scale. The most important finding is that restructuring mainly depended on an increase in the factor productivity by reducing employment and selling assets without significant increase in the TFP.

To illuminate the state and countermeasure of soilless cultural production and marketing in Korea, the survey of soilless cultural production through Agricultural Agent Center, questionnaire, field investigation, and literature analysis were performed. Soilless cultural farm-houses were 82 and area was 11.1 ㏊ on September, 1992. But its area of chief producing district and kind of crops are rapidly being changed. To solve the problems of soilless culture in Korea; old age and low education of farmers, small cultural area, financial difficulty, none standardization of facilities material and none specialization of varieties for soilless culture, it must be actively put in practice for soilless cultural improvement of Korea that the technical education strengthenning, financial support by government, standardization of facilities material and variety specialization. Poor sales network and policy, poor marketing intelligence network and activities, negligent selection and packing of products become the major cause of soilless culture's failure. Therefore, spontaneous sales network organization, marketing support of Horticultural Cooperative Association and Agricultural Cooperative Association, elevation of marketing intelligence power, and continuous effort of farmer for successful selection and packing of products are essential factors for soilless cultural development of Korea. Soilless culture is a royal road to change from primary agriculture to secondary agriculture for agricultural innovation, but there are many problems in this system and it is difficult to solve that problems by only farmer's effort. Therefore, not only farmer but also researcher, scholar, related groups and government concentrate their effort on solution of soilless cultural problems.

교정치료에서 고정원의 조절은 교정 장치의 선택과 적용에서 가장 중요한 요소 중 하나이다. 이 연구의 목적은 교정용 미니스크류의 식립 즉시 교정력을 적용한 군과 교정력을 적용하지 않은 군의 제거회전력 측정과 조직학적 분석을 통해 즉시 교정력을 가한 미니스크류의 고정원으로서의 안정성을 확인하여 식립 후 교정력을 적용 수 있는 시기의 선택에 도움을 주고자 하는 것이다. 외경 1.6 mm, 길이 8 mm인 총 40개의 타이타늄 미니스크류를 10마리 가토의 경골에 식립하였다. 20개의 미니스크류 실험군은 식립 직후부터 6주동안 지속적인 200g의 교정력을 적용하였고 나머지 20개의 미니스크류 대조군은 교정력을 적용하지 않았다. 제거 회전력은 디지털 토크 게이지를 이용하여 측정하였으며 t-test를 이용하여 통계처리 하였고, 조직표본은 미니스크류를 제거한 후 H-E 염색하여 조직 소견을 관찰하였다. 제거회전력은 실험군과 대조군에서 통계학적으로 유의성 있는 차이를 보이지 않았으며, 조직학적으로 두 군간의 차이는 없었다. 본 연구의 결과는 교정용 미니스크류에 즉시 교정력을 가하더라도 안정적인 고정원으로 활용할 수 있다는 점을 제시한다. Objective: The purpose of this experimental study was to evaluate the effect of immediate orthodontic loading on the stability at the bone-implant interface of titanium miniscrews in a rabbit model. Methods: Forty titanium miniscrews (1.6 mm diameter, 8 mm length) were inserted in the tibiae of 10 rabbits. Twenty test group miniscrews were subjected to continuous orthodontic forces of 200g immediately after implantation for a period of 6 weeks. The remaining 20 control group miniscrews were left unloaded for the same follow-up interval. Removal torque values were recorded using a digital torque gauge. An independent t-test was performed. Results: All the miniscrews were stable, and exhibited no mobility or displacement throughout the experimental period. Histologically, miniscrews were well-integrated into bone. No statistically significant differences in removal torque data were found between the loaded test and the unloaded control groups. Conclusions: These findings suggest that titanium miniscrews can be used as anchoring units for orthodontic tooth movement immediately after insertion.

Background : Previous data have been reported that subtype B is prevalent in South Korea, but neither the extent nor the proportion of subtypes could be evaluated. This study was designed to analyze the distribution of HIV-1 subtypes, temporal instructions and transmission dynamics between epidemiological groups. Methods : 1,280 Koreans had been diagnosed as HIV seropositive during the period 1985 to 2000. Among them, 134 individuals were selected for this molecular epidemiological study. 134 DNAs were isolated from uncultured or cultured peripheral blood mononuclear cells. V3-V5 (0.7 kb) fragment of HIV-1 env gene was amplified by nested polymerase chain reaction and was sequenced. Results : HIV-1 isolates from thirty-seven homosexuals were all subtype B (100%). On the other hand, 66 isolates from 94 heterosexuals were subtype B (70%) and 28 were non B subtypes (30% : 13 A, 4 C, 2 D, 8 E , 1 G). Only subtype B strains were isolated from 73 males who were infected with HIV inside Korea while 16 B and 20 non B subtype strains were isolated from 36 males who were HIV infected outside of Korea. However, B and non B strains were isolated half and half from females who were infected inside Korea except one. Conclusion : The HIV-1 subtype B strains are prevalent in Korea from the early HIV infection until present in both homo and heterosexuals. Non B strains have been transmitted from men who were infected outside Korea to their spouses and casual partners. So, we need further study to monitor subtype B and non B HIV transmission in epidemiological groups of Korea, (Korean J Infect Dis 33:311∼318, 2001)

Epitaxial Growth of Boron-doped Si Film using a Thin Large-grained Si Seed Layer for Thin-film Si Solar Cells

Kang, Seung Mo,Ahn, Kyung Min,Moon, Sun Hong,Ahn, Byung Tae Korea Photovoltaic Society 2014 Current Photovoltaic Research Vol.2 No.1

We developed a method of growing thin Si film at $600^{\circ}C$ by hot wire CVD using a very thin large-grained poly-Si seed layer for thin-film Si solar cells. The seed layer was prepared by crystallizing an amorphous Si film by vapor-induced crystallization using $AlCl_3$ vapor. The average grain size of the p-type epitaxial Si layer was about $20{\mu}m$ and crystallographic defects in the epitaxial layer were mainly low-angle grain boundaries and coincident-site lattice boundaries, which are special boundaries with less electrical activity. Moreover, with a decreasing in-situ boron doping time, the mis-orientation angle between grain boundaries and in-grain defects in epitaxial Si decreased. Due to fewer defects, the epitaxial Si film was high quality evidenced from Raman and TEM analysis. The highest mobility of $360cm^2/V{\cdot}s$ was achieved by decreasing the in-situ boron doping time. The performance of our preliminary thin-film solar cells with a single-side HIT structure and $CoSi_2$ back contact was poor. However, the result showed that the epitaxial Si film has considerable potential for improved performance with a reduced boron doping concentration.
