In Korea, global warming caused by the climate changes impacted on weather system with increase in frequency and intensity of precipitation, and the rainfall pattern changes significantly by regional groups. Furthermore, it is expected that the regional and annual fluctuation ranges of the rainfall in the future would be more severe. Nowadays, agricultural drainage system designed by the existing standard of 20-year return period and 2 days of fixation time cannot deal with the increment rainfall such as localized heavy rain and local torrential rainfalls. Therefore, it is required to reinforce the standard of the drainage system in order to reduce the agricultural flood damage brought by unusual weather. In addition, it is needed to improve the standard of agricultural drainage design in order to cultivate farm products in paddy fields as facility vegetable cultivation and up-land field crop have been damaged by the moisture injury and flooding. In order to prepare for the changes of rainfall pattern due to climate changes and improve the agricultural drainage design standards by the increase of cultivating farm products, the purpose of this study is to examine the impact of climate changes, the changes of relative design standard, and the analytic situation of agricultural flood damages, to consider the drainage design standard revision, and finally to prepare for enhanced agricultural drainage design standards.

As compared before, agricultural machines are used more commonly instead of animal or manpower in rural areas and the injuries due to those are common. This study was conducted by questionnaire method in order to find out the current status of injuries due to agricultural machines for farmers who was selected from three Gun's in Kyeongsangnam Province. The study subjects were 385 persons in all(210 male persons, 175 female reasons) and the study period was from July through September 1993. The results were as follows; 1. The injury rate due to agricultural machines was high in male(p<0.05), and it was higher in younger age group and higher educated group. 2. The injury occurred high in summer and autumn seasons(77.6%), in the afternoon(60.6%), and during harvest(35.2%). 3. The major injuries were contusion, fracture, amputation in order and the injured sites were arms, legs, and chest in order. 31.7% of the injured farmers had been admitted, and they were treated at hospitals, home, drugstores and health centers in order. 4. The casualty damage was highest by cultivators, and agricultural instruments, threshing machine were followed. Among traumatic injuries concerned with cultivators contusions were most common, and fractures, amputations were followed. In case of agricultural instruments bruises were most common, and incisions, contusion were followed. In case of threshing machines fractures were most common and contusion, bruise were followed.

The objectives of this study are to analysis structural characteristics of small scale vinyl house and to develope structural analysis program for optimum design. The variation of maximum section forces along the structural characteristics, location and number of purlin was analyzed in vinyl house. It was concluded that the developed structural analysis program could be used usefully for optimum design of small scale vinyl house.

This study is that analyzes the flood damages caused by rainfall during typhoon and how inundated area should be affected. Using HEC-HMS for analyzing rainfall-runoff and GIS (Geography Information System) for analyzing inundated area and volume. Each model was applied to Seopyung area for runoff effect analysis. As the result, Damaged area was magnified gradually according to the increase of rainfall and GIS was good for calculating the exact flood damage area at varied time.

최근의 이상 기후현상은 수목의 개화시기 변화를 가져오고 나아가 수목 피해를 초래하기도 한다. 산림의 쇠퇴에 대하여는 국내외적으로 많은 연구가 이루어져 있으며(Krause et al, 1986; Kitajima, 1988) 이러한 쇠퇴림은 수분스트레스에 민감할 것으로 보고되었다(Hauhs and Wright, 1986; Ulrich, 1990).(중략)

The research significance of the paper is to identify the major properties of synthetic lightweight concrete that are affected by ASR expansion and to determine the extent and magnitude of the loss in these properties. Emphasis is also given to the use of non-destructive testing techniques ; Such as dynamic modulus of elasticity and ultrasonic pulse velocity, to examine whether these methods could be used to identify the initiation of expansion and the internal structural damage caused by ASR.
