This survey was conducted to secure a basic data for the effective training programs that might be an essential part of any successful mechanization of agriculture in Korea. Chung Nam provincial training center and 17 guidance offices with farm machinery training centers which were thought to be a medium level on their scale in whole country were selected in the survey on its training accomplishments, stafts, facilities, schedule and number of trainees at one time or in a class. The results and recommendations from this survey were as follows; To enhance the effect of farm machinery training, it was absolutely necessary for city or county training center to complement its facilities and equipments. It might be desirable that instructors of each training center should be the one educated or highly trained in the institution of farm machinery, and that the number of technical assistants should be increased and their present part time working condition should be changed to full-time status. It was recommended that training for farmers should be scheduled during off-season so that farmers could participate in the training couses, and that the number of trainees in a class should be reduced to about 10 trainees, which was approximately a fourth of the present situation.

“low and old age trend” is a big social national problem in korea but also in foreign countries. The Government pursues a policy for aged people to take part in construction site as labours. Low childbirth and avoidance of 3D work kinds lead to exposure of aged workers to industry work places. According to korea department of labour, it is expected that 18% of total economic activity people in 2008 to 27.2% in 2018 be increased with age of more than 55 old years. Therefore, It is needed that more countermeasures for old workers should be taken for safer work conditions. This old workers with more than 55 old years contain major portion of accident occurrence in construction industry. It is found that accident rate in construction industry can be decreased if appropriate technical safety training is provided to them who wish to work at construction sites. Statistic analysis such as frequency, cross, logistic regression using program package SPSS 13.0 has been made after collecting questionnaire survey of more than 330workers at construction sites

As engine is produced with foreign technology, basic data for cooling fan are very few in korea. Therefore, an experiment was performed to obtain data on cooling fans for the cooling system. The results obtained are summarized as follows: 1. Efficiency of cooling fan was 49.9% while the engine eras running at the rated power. 2. Shaft power of the fan was 0.5 kW maximum at the rated power. 3. Air flow rate of the fan was 12.9㎥ /min. at the rated power. 4. Static pressure of the fan was 29.8 mmHg at the rated power,

비만과 관련된 질환은 당뇨병, 고혈압, 고지혈증, 죽상경화증(동맥경화증), 심근경색증, 지방간, 담석증, 골 관절염, 통풍, 폐쇄성 수면 무호흡증, 대장암, 직장암, 전립선암, 유방암, 자궁내막암 등의 각종 암, 불안, 우울, 적응장애, 히스테리 등의 심리적 질환 등이 있다. 비만이 있을 때 우리 몸에서는 인슐린 자체에 대한 저항성이 생겨서 말초조직에서의 포도당 이용이 감소된다. 연구에 의하면 표준체중의 45$\%$ 이상을 초과한 비만환자는 당뇨병 발생의 위험도가 30배 증가된다고 알려져 있다. 비만이 있을 때 흔히 동반되는 질환들 중 특히 고혈압, 고지혈증, 죽상경화증 등의 질환은 당뇨가 있을 때 흔히 동반될 수 있는 질환들이고, 인슐린 저항성과 깊은 관계가 있는 질환들로 당뇨인들에게 비만은 매우 중요한 질환이라고 할 수 있겠다.

Background and PurposeaaElevated plasma total homocysteine (tHcy) levels are reported to be associated with an increased risk of Alzheimer’s disease (AD). However, the mechanism by which homocysteine contributes to the pathogenesis of AD is as yet unknown. The aim of this study was to elucidate the relationship between white matter changes (WMC) and medial temporal lobe atrophy (MTA) on brain magnetic resonance imaging (MRI), and plasma levels of tHcy in AD patients. MethodsaaSeventy-two patients with a clinical diagnosis of probable AD were recruited to the study. Plasma tHcy levels, vascular risk factors, and WMC and MTA on brain MRI were evaluated in all patients. The AD patients were classified into two groups: those with no or minimal WMC (69.2±8.8 years, mean±SD, n=36) and those with moderate-to-severe WMC (74.6±4.6 years, n=36) on brain MRI. ResultsaaIn a univariate logistic regression analysis, the risk of moderate-to-severe WMC in AD was significantly associated with increasing age, female gender, lower education level, hypertension, high plasma tHcy levels, and lower Mini-Mental State Examination (MMSE) score. Multivariate logistic regression analysis revealed only high plasma tHcy as the independent and significant risk factor for moderate-to-severe WMC [odds ratio (OR; adjusted for age, gender, education level, MMSE score, and hypertension comparing the top tertile - tHcy levels ≥12.9 μmol/L - with the bottom tertile - tHcy levels ≤9.4 μmol/L)=7.35; 95% confidence interval, confidence interval=1.36-39.84; p=0.02], and age as a borderline significant risk factor (OR=1.08, 95% CI=0.99-1.19, p=0.09) in AD patients. Plasma tHcy levels were not correlated significantly with either right or left MTA. ConclusionsaaOur results suggest that the vascular pathway mediates the association between elevated plasma tHcy levels and AD.
