The purpose of this study was to investigate the leadership style and development of agricultural organization in Korea. Specific objectives of the study were to : 1) identify the leadership style of agricultural organization though literature review, 2) survey the members' opinions about their leadership style, 3) examine the leader's self-estimation of their leadership style, 4) identify the desirable leadership style items of the leaders and members, 5) suggest effective way to the development of leadership style. The study was carried out through literature review and questionnaire survey. Total of 715 farmers were surveyed to collect data, and 501 responded. The statistical techniques applied on the data are frequency, percentile, analysis of variance, multiple regression utilizing the SPSS/WIN, and the statistical significance was tested at .05 level. The major findings of the study were: 1) the leaders motivation and problem solving abilities of agricultural organizations were not enough to satisfy the members, 2) members believed the leaders make somewhat arbitrary decisions, 3) the leaders of the organizations had difficulties to coordinate the different opinions of the members, and 4) the leaders of the organizations felt the need of skills and information on leadership style and development of agricultural organization. For improvement of leadership for agricultural organization, this study suggests; 1) the more education programs should be made and practiced to make their leadership special, 2) all members should make much efforts to have channels for rational communication, 3) the leaders have to give members well-polished incentives for active participation, 4) more governmental support should be given to empower those organizations, and 5) the agricultural organizations, universities and government must establish a strong coordinating system to realize above suggestions.

This study explored the effects of adoption of innovation and resistant attitude on farmers' perspectives and also was deigned for developing prompt spread of ICT and facilitating stronghold support center in the convergence agricultural field. To closely examine the variation for exploitation intent of stronghold support center in the ICT convergence agriculture, 110 farmers who had experienced introduction for ICT hybrid environmental control system were participated in the study using the questionnaire. The results revealed the several findings. Firstly, there was no significant differences between the self-efficacy such as confidence of application technology for farmers and adoption of innovative technique (p=.075). Secondly, suitability of using ICT hybrid environmental control system showed a significant difference in the adoption of innovation (p=2.750) while complexity of using ICT hybrid environmental control system indicated the negative effects on the adoption of innovation (p=3.591). Thirdly, introduction cost of ICT hybrid environmental control system showed the negative effects in the adoption of innovation (p=2.278), whereas adoption of innovation indicated a significant difference in the stronghold support center in the convergence agricultural field (p=5.500). Finally, resistance of ICT adoption of innovative technique revealed the negative effects on the stronghold support center in the ICT convergence agriculture. This study, therefore, demonstrated that educational assistance for acquiring ICT technique, suggestion of influences for productivity, and development for skills were needed to extend ICT convergence technology. Additionally, the study indicated the strategies related with promotion as well as ways of minimizing introduction cost.

The purpose of this study was to identify differences by business motivation of agro-healing farm s in Korea. A survey was conducted for entrepreneurs in agro-healing farmers with self-administered questionnaires. Main results of this study were as follows: First, business motivation of agro-healing farm s in Korea can be classified to 1) education-oriented, 2) care-oriented, and 3) sale revenue-oriented motivation. Second, care-oriented farms provide healing services to people in need like the disabled. These farms may be required a long-term program such as residence-required format. And these farms need supports of health and medical service personnel or institutions. Third, sale revenue-oriented farms have sources of main income from agricultural products or processed goods made in these farms. Therefore, these farms may be required a business strategy such as product development, marketing rather than agro-healing programs. fourth, the estimation of a Multinominal logistic regression model determines the characteristics of agro-healing entrepreneurs who are most likely to opt for each type motivation of participating for agro-healing farm business. the most important determinants on business motivation of agro-healing farms were 'participants type in programs', 'program operating time', 'supporting health and medical service personnel or institutions' and 'program revenue ratio in farm operating revenue'.

This experiment was carried out to select suitable organic matter in To-jik nursery (self soil nursery) for complement To-jik nursery's defects that are deterioration of raw material by poor quality of seed ginseng and reduction of the quantity in seed ginseng production. Organic matter used were Yacto, rice bean, defatted rice bran, soybean cake and their mixture. As follows, bulk density in soil physical property by treating organic composts was the greatest in soybean cake and the next was followed by mix, Yacto, defatted rice bran, and rice bran treatment in order. Soil pore space ratio was totally the opposite; that was rice bran the first and followed by defatted rice bran, Yacto, mix and soybean cake treatment. The incidence rate of damping off by treating organic composts was 1.5% in both soybean cake and mix while the others was 1.0%. Emergence time was the same among treatment on April 16 and Emergence rate was the highest at 73% in Yacto. There was no significant differences among treatment in the growth of aboveground part but it was a little better in defatted rice bran treatment. In Yacto treatment, the growth of underground part, total root number per kan, rate of first grade ginseng seedling, and rate of usable ginseng seedling etc. were entirely higher but there was little differences. Using defatted rice bran was slightly lower in productivity compared to Yacto, but the possibility was high as a alternative for Yacto in a view of managing cost down.

Background: Carpal tunnel syndrome (CTS) is a common work-related peripheral neuropathy. In addition to grip force and repetitive hand exertions, wrist posture (hyperextension and hyperflexion) may be a risk factor for CTS among workers. However, findings of studies evaluating the relationship between wrist posture and CTS are inconsistent. The purpose of this paper was to conduct a meta-analysis of existing studies to evaluate the evidence of the relationship between wrist posture at work and risk of CTS. Methods: PubMed and Google Scholar were searched to identify relevant studies published between 1980 and 2012. The following search terms were used: "work related", "carpal tunnel syndrome", "wrist posture", and "epidemiology". The studies defined wrist posture as the deviation of the wrist in extension or flexion from a neutral wrist posture. Relative risk (RR) of individual studies for postural risk was pooled to evaluate the overall risk of wrist posture on CTS. Results: Nine studies met the inclusion criteria. All were cross-sectional or case-control designs and relied on self-report or observer's estimates for wrist posture assessment. The pooled RR of work-related CTS increased with increasing hours of exposure to wrist deviation or extension/flexion [RR = 2.01; 95% confidence interval (CI): 1.646-2.43; p < 0.01: Shore-adjusted 95% CI: 1.32-2.97]. Conclusion: We found evidence that prolonged exposure to non-neutral wrist postures is associated with a twofold increased risk for CTS compared with low hours of exposure to non-neutral wrist postures. Workplace interventions to prevent CTS should incorporate training and engineering interventions that reduce sustained non-neutral wrist postures.

GIDL(Gate-Induced Drain-Leakage)을 줄일 수 있는 새로운 구조의 ESD(Elevated Source Drain) MOSFET을 제안하고 분석하였다. 제안된 구조는 SDE(Source Drain Extension) 영역이 들려진 형태를 갖고 있어서 SDE 임플란트시 매우 낮은 에너지 이온주입으로 인한 저활성화(low-activation) 효과를 방지 할 수 있다. 제안된 구조는 건식 식각 및 LAT(Large-Angle-Tilted) 이온주입 방법을 사용하여 소오스/드레인 구조를 결정한다. 기존의 LDD MOSFET과의 비교 시뮬레이션 결과, 제안된 ESD MOSFET은 전류 구동능력은 가장 크면서 GIDL 및 DIBL(Drain Induced Barrier Lowering) 값은 효과적으로 감소시킬 수 있음을 확인하였다. GIDL 전류가 감소되는 원인으로는 최대 전계의 위치가 드레인 쪽으로 이동함에 따라 최대 밴드간 터널링이 일어나는 곳에서의 최대 전계값이 감소되기 때문이다.

In an attempt to investigate the effect of a muscle strengthening exercise program on muscle strength, pain, depression, self-efficacy and quality of life of patients with knee osteoarthritis, a pre-experiment, one group pre-test & post-test design, was planned. Muscle strengthening exercise was carried out from May 22 through August 14, 1995 at isokinetic exercise room in rehabilitation department of University Hospital in Taejon. The subjects were seven female clients conveniently sampled from University Hospital located in Taejon, between 39 and 61 years of age, who had a osteoarthritis in knee. Muscle strengthening exercise program was composed of three sessions per week, one isokinetic exercise at angular velocity of 60° and 180° with Cybex isokinetic dynamometer and two resistance home exercise sessions with elastic band. Data were analyzed with frequency, percentage of change, Friedman test, Duncan test using SAS program. Results were obtained as follows : 1) Flexion and extension muscle strength at angular velocity of 60° and 180° were increased after 12weeks' exercise than those of before experiment. But exept flexion muscle strength at angular velocity of 180°(F=3.34, P=0.0261), there was no statistically significant difference among muscle strengths, which is measured every 3 weeks. 2) Pain was decreased after 6weeks' exercise than that of before experiment, and after 12weeks' exercise than that of 6weeks' exercise. There was statistically significant difference (F=4.28, P=0.0396). 3) Depression was increased after 6weeks' exercise than that of before experiment, and after 12weeks' execise than that of 6weeks' exercise. There was no statistically significant difference between before experiment and after 6weeks' exercise. But, there was statistically significant difference between after 6weeks' exercise and 12weeks' exercise(F=9.38, P=0.0035). 4) Self-efficacy was decreased after 6weeks' exercise than that of before exercise. But, it was increased after 12weeks' exercise than that of be-fore exercise and after 6weeks' exercise. But there was no statistically significant difference (F=1.46, P=0.2706). 5) Quality of life was increased after 6weeks' exercise than that of before exercise, and after 6weeks' exercise than that of 12weeks' exercise. But there was no statistically significant differ once (F=1.06, P=0.3816). Thus, the significant of muscle strengthening exercise for the improvement of muscle strength, pain, depression, is verified. But, this study was a pre-experiment with small size subjects. So, con-trolled experimental study is necessary to determine the effect of this muscle strengthening exercise program on muscle strength, pain, depression, self-efficacy, and quality of life of patients with knee osteoarthritis.
