임창수,Rim, Chang-Soo 한국수자원학회 2017 한국수자원학회논문집 Vol.50 No.11

본 연구에서는 우리나라 56개 연구지역에 대해서 증발량 산정방법 중에 하나인 공기동력학적 방법의 적용성을 검토하였다. 이를 위해 과거 연구자들에 의해서 제안된 공기동력학적 증발량 산정식들을 7가지 형식으로 구분하고 일반화하여 증발량 산정모델을 유도하였다. 또한, 공기동력학적 방법 적용에 필요한 기상요소자료들(풍속, 포화미흡량, 기온, 대기압)을 이용하여 4가지의 다변량 선형회귀모델을 유도하고 그 적용성을 검토하였다. 기상자료들의 자기상관의 영향을 고려하기 위해 변수들을 차분시켜 회귀분석을 실시하고 자기상관을 고려하지 않은 경우와 비교한 결과 결정계수 값에 큰 차이가 없음을 확인하였다. 연구결과에 의하면 공기동력학적 모델이나 다변량 선형회귀모델 모두에서 산정된 월 증발량과 관측된 월 증발량 사이에 매우 높은 상관성이 있는 것으로 나타났다. 하지만 대부분의 증발량 산정모델에서 8, 9, 10, 11, 12월에 증발량을 과다 산정하고 있는 것으로 나타났다. 다변량 선형회귀모델들에 사용된 기상요소자료들은 모두 증발량 산정에 유의한 영향력이 있는 것으로 나타났으며, 특히 포화 미흡량이 가장 중요한 기상요소이며, 두 번째로는 기온, 세 번째로는 풍속, 그리고 마지막으로 대기압인 것으로 나타났다. In this study, applicabilities of aerodynamic approaches for the estimation of pan evaporation were evaluated on 56 study stations in South Korea. To accomplish this study purpose, previous researchers' evaporation estimation equations based on aerodynamic approaches were grouped into seven generalized evaporation models. Furthermore, four multiple linear regression (MLR) models were developed and tested. The independent variables of MLR models are meteorological variables such as wind speed, vapor pressure deficit, air temperature, and atmospheric pressure. These meteorological variables are required for the application of aerodynamic approaches. In order to consider the effect of autocorrelation, MLR models were developed after differencing variables. The applicability of MLR models with differenced variables was compared with that of MLR models with undifferenced variables and the comparison results showed no significant difference between the two methods. The study results have indicated that there is strong correlation between estimated pan evaporation (using aerodynamic models and MLR models) and measured pan evaporation. However, pan evaporation are overestimated during August, September, October, November, and December. Most of meteorological variables that are used for MLR models show statistical significance in the estimation of pan evaporation. Vapor pressure deficit was turned out to be the most significant meteorological variable. The second most significant variable was air temperature; wind speed was the third most significant variable, followed by atmospheric pressure.

Patterns of brain-stem compression and secondary brain-stem evoked postentials were investigated to correlate with expanding mass volume and location in mass-induced supratentorial brain compression in cats in which the subjects were divided into four experimental group i.e., frontal, temporal, parietal, and occipital brain-compressed groups. Postmortem inspection of the brain-stem showed either unilateral or bilateral dorsal herniation of the brain in frontal and temporal brain-compressed groups and dorsolateral herniation in parietal and occipital brain-compressed groups, respectively. Microscopic examination revealed that the secondary brain-stem hemorrhages were mostly caused by venous bleeding secondary to venous congestion, the bleeding being more severe in occipital brain-compressed group. As the intracranial pressure was raised by expansion of a supratentorial balloon, the late components of the BSEP were suppressed first, followed by the suppression of the early components. In BSEP recording. a significant change was observed in Vth wave with prolongation of latency and decrease in amplitude. This finding suggests that the midbrain is the most vulnerable to compression ischemia. In parietal group, the Vth wave started to be prolonged at 0.4㎖ of balloon expansion and totally disappeared at 1.8㎖ of expansion.

This study suggests a plan to expand the rural experience program linked to natural disaster through the case analysis of the village of Garisan-ri, Inje-gun, Gangwon-do, Republic of Korea. This will help to establish the necessary improving and policies for Re-leap of rural villages in disaster areas and activation of rural experience villages. The local residents have created flood recovery stories, disaster response content, and disaster prevention camp sites, all of which have been hit by serious disaster damage. It has also contributed to the revitalization of the village by providing various experience programs such as disaster response training, crossing rapids, and evacuation experience. This is a way to get rid of the negative perception of disaster and utilize it. The conversion of idea through disaster experience content contributed to the activation of the area. By linking the disaster experience contents to the rural experience program in the future, it can be helpful to avoid the duplication of contents and limit the similar operation method, which is an existing problem of rural experience villages.

Rural house came into the rapid change through the process of modernization and Saemaul movement in the past. This change continue to the current era, there is a such exotic forms and indiscriminate development of new house and Saemaul housing and existing conventional farmhouse in rural area. Such a phenomenon, ultimately creating disharmony in traditional environment of rural. In this respect, reflecting the location characteristics of the region which is based on the regional characteristics and unique model of rural housing, it is absolutely required for the development of rural housing customized to fit the diversity of modern. With that background, the purpose of the research is to try and find out the changes in rural houses and the transforming characteristics. To achieve this research purpose, this research selected a specialized magazine for architecture. Then, it identified contents which has specific keyword. lastly, it analyze type and contents of house in rural area from selected article. This process make up the rural housing for effective utilization. The result showed that the type of economic activity and residents information directly show the character of the members who located in the new homes after retuning to farming. The polarization of structure was clearly visible by the building time. And, propensity to western-style of major components was very high such as shape and form of housing. However, it was found to prefer to reflect traditional aesthetics in the components of the housing partially. Therefore, more research is needed to reflect of the results of a survey. Also, analyzing the characteristic of rural house’s element and suggesting ways to take advantage in order to present suitable element of modern rural house.
