This experiment was conducted to elucidate the relation-ship between vertical distribution of rice roots and yield traits under field conditions. Eight IRRI's new plant type rices (NPTRs) were tested in a volcanic ash soil paddy field under dense (IO 10 cm) and common (20 20 cm) planting densities. These lines were evaluated to have more spikelet numbers per panicle (SNP), lower filled grain rate (FGR), and lower rough grain weight per hill (RGWH). In dense planting, rough grain weight per stem (RGWS) was increased due to heavier culm and leaf dry weight (CLDW), and both RGWS and CLDW were related with the percentage of root distribution (%RWI) in the 10~30 cm soil layer, while in common planting, RGWS was not closely related with CLDW. SNP was highly related with root dry weight (RDW) in the 0~10cm soil layer. FGR was mainly affected by ROW in the 10~30 cm soil layer under both planting densities. RGWS was positively correlated with top dry weight (TDW) and harvest index (HI), and TDW was positively correlated with RWI under common planting or %RWI under dense planting, and HI was positively correlated with RWI in the 10~30 cm soil layer only under dense planting. RGWS was closely related with root weight index by dry weight (RWI) in the 10~30 cm soil layer and %RWI in the 0~30 cm or 10~30 cm soil layer under dense planting, and with only RWI in the 10~30 cm soil layer under common planting. But RGWH showed the close positive relationship with RDW and RWI in the 10~30 cm soil layer under dense planting, while under common planting, it showed the close positive relationship with RWI and %RWI in the 10~30 cm soil layer or %RWI in the 0~30 cm soil layer. The deeper root system in rice, especially under dense planting, is important for high yield of NPTRs focusing on the increment of top mass production and harvest index.

본 연구에서는 선물할 때 선물할 대상과의 관계에 따라 어떤 대안을 선택하는지에 관해 알아보았다. 구체적으로 두 대안의 가격대가 비슷할 때, 브랜드 지위가 높지만, 브랜드 내 모델 랭킹은 낮은 제품과 브랜드 지위는 낮지만, 모델 랭킹은 높은 제품중 어떤 대안을 더 선호하는지에 관해 실험을 통해 연구하였다. 해석 수준 이론(Construal level theory)을 바탕으로 선물할 대상과의 관계(수직적 관계 vs. 수평적 관계)와 친밀도에 따라 카테고리 효과(category effect, 높은 지위 브랜드의 낮은 랭킹 모델 선호)와 랭킹 효과(ranking effect, 낮은 지위 브랜드의 높은 랭킹 모델 선호)가 다르게 나타난다고 제안하였다. 연구 결과, 심리적 거리에 따라 대안의 선택이 달라짐을 확인할 수 있었다. 구체적으로 수직적 관계에 있는 대상에게 선물할 경우에는 카테고리 효과가 크게 나타났지만, 선물할 대상이 수평적 관계인 경우에는 랭킹 효과가 나타났다. 또한 수직적 관계와 비교할 때, 수평적 관계에서 친밀도에 따른 랭킹효과(또는 카테고리 효과)의 차이가 더 크게 나타났다. 이처럼, 본 연구에서는 선물할 대상과의 관계와 친밀도의 심리적 거리에 따라서 브랜드 지위와 모델 랭킹에 대한 제품의 선택이 달라질 수 있다는 것을 보였다.

Continuing advances in the formulation and solution of risk-sensitive control problems have reached a point at which this topic is becoming one of the more intriguing modern paradigms of feedback thought. Despite a prevailing atmosphere of close scrutiny of theoretical studies, the risk-sensitive body of knowledge is growing. Moreover, from the point of view of applications, the detailed properties of risk-sensitive design are only now beginning to be worked out. Accordingly, the time seems to be right for a survey of the historical underpinnings of the subject. This paper addresses the beginnings and the evolution, over the first quarter-century or so, and points out the close relationship of the topic with the notion of optimal cost cumulates, in particular the cost variance. It is to be expected that, in due course, some duality will appear between these notions and those in estimation and filtering. The purpose of this document is to help to lay a framework for that eventuality.

18c, statues of French Lacquer Furniture are worthy of close attention in aspects of its quantity , quality and asthetics in production. This kind of furniture have been developed, devising the its own original techniques, through it was influenced and begun with the imported from China. Therefore, the main currence of color with black tones had changed to French style, with somewhat repleting to chinese ornament. This characteristics is distinguished in furniture which is expressed as a min theme. It can say that it has the meaning of lacquer furniture as part of chinoiserie prevailing at the time that social consensus through the political supports for upbringing furniture industry, a close relationship of clients , merchants, and descorators with appreciative eyes, and the ceaseless persuit of the new had made resulted in concurrence of asthetics between the eastern world and the western world.

Air transport industry tries to enhance punctuality, stability and amenity for customer's satisfaction. Especially airlines and airports do make an effort as the distance between these two stakeholders and passengers are close. This research has empirically discussed the relationship between duty free shop purchase of passengers and the number of flights and hours of schedule delay at the airport. According to the result, the total sales of duty free shop sales have meaningful influence on the number of flights and hours of delay. In order to decrease such an impact, close cooperation between airports and duty free shops required.

This study aims to identify the structure and system to make close relationship among planning elements, legal regulation and evaluation index toward sustainable development in the ecological housing estate. Through these close relationships the ecological housing estate could get more sustainability. With this consideration, this study consists of following three parts. First, we review the key issues of sustainability in ecological housing which are focused on the energy-efficient planning. Second, we extract the planning elements, legal regulation and evaluation index using the qualitative system dynamics that is found out all phenomenons from viewpoint of closed loop thinking and circular feedback system. Third, we analyse the correlationship among them in terms of energy efficient planning in the ecological housing estate. Finally, we summarize the findings toward sustainability in ecological housing estate through these analysis.

The purpose of this study was to examine elderly using behavior and propinquity of neighborhood facilities and to analyze the relationship of propinquity and using behavior of each neighborhood facility. The results of the study indicated that the elderly are using more frequently and living more close to leisure facility such as sports/health facility, hobby/education facility, and entertainment facility. Age and health status of the elderly were the important factors on the use and propinquity of neighborhood facilities. On the other hand, the elderly having higher education and economic status were more likely to use and live close to leisure facilities. For the elderly, the need of physical propinquity to neighborhood facilities and providing information about the facility location were required. For the mid-aged people, the education about leisure culture of the later-hood years were suggested since the use of neighborhood facility is depending on one's habit.

Room temperature Li+ ion conductivities of Li3xLa(2/3-x)TiO3 system with x=0.117~0.317 were measured by complex impedance method. ICP, SEM and XRD analysis were conducted to study the main factor which influence the Li+ ion conductivity. Li+ ion conductivity seems to have a close relationship with the crystal structure of primitive cell increase as the primitive cell as close to cubic.

The purpose of this study is to investigate social relationship and housework implementing of the elderly households in Chungbuk and to provide suggestion s from the perspective for the well-being of the elderly. The data of this study are collected through questionaire and the data of 244 respodents are analyzed using Frequency Contingency analysis one-way ANOVA. The results are as follows: firstly most elderly tend to have a close relationship with their neighbors in their houses. The activity of social relationship is routine behavior and the satisfaction of social relationship with their neighbors is high, The older the age the lower the education level and the poorer in physical health the more frequently they meet their neighbors and friends the more frequently they go to establishments for elderly and tend to play games such as a flower cards game. Secondly the average time implementing housework by elderly women is about 3.63 hours. The attitude toward housework is a l ttle negative. The average housework eqipments owned by them are 4.8 The older the poorer in physical health the lower level of owning housework equipments the shorter is the time implementing housework and the more negative is the attitude toward housework.
