We could see that, the thinner the retaining wall is, the more advantageous Premixed Agent Type Waterproof method is in the aspect of economic efficiency. The reason is because, in the case of Premixed Agent Type Waterproof method, the thicker the retaining wall is, the higher the construction cost increases due to increase in the material quantity required which increases in proportion to the area in the case of Premixed Agent Type Waterproof method. We could see that, the thinner the retaining wall is, the more inferior the economic efficiency of Infiltration Type Waterproof method is to that of Premixed Agent Type Waterproof method, as, in the case of Infiltration Type Waterproof method, the quantity of material required is fixed in proportion to the area. Consequently, we concluded that Premixed Agent Type Waterproof method is economically advantageous up to the wall thickness of 700 mm and Infiltration Type Waterproof from 800 mm.

The purpose of this paper is to develop a method of the sensitivity analysis that can be applicable to a degenerate tree solution of the minimum cost flow problem. First, we introduce two types of sensitivity analysis. A sensitivity analysis of Type 1 is the well known method applicable to a spanning tree solution. However, this method have some difficulties in case of being applied to a degenerate tree solution. So we propose a sensitivity analysis of Type 2 that keeps solutions of upper bounds remaining at upper bounds, those of lower bounds at lower bounds, and those of intermediate values at intermediate values. For the cost coefficient, we present a method that the sensitivity analysis of Type 2 is solved by using the method of a sensitivity analysis of Type 1. Besides we also show that the results of sensitivity analysis of Type 2 are union set of those of Type 1 sensitivity analysis. For the right-hand side constant or the capacity, we present a simple method for the sensitivity analysis of Type 2 which uses arcs with intermediate values.

This study analyzed the presentation trend of a checklist method for trench coat designs. Through this analysis, this study examined the flow of trench coat designs and presents future design directions. Research was conducted in the following method. A total of 1,307 female trench coat photos were selected from the photos presented in the top 4 collections from 2006 to 2011. These photos were used for analysis and frequency analysis was conducted. Among the checklist methods presented in trench coats, the modification type was most common, followed by the elimination type, conversion type, combination type, minimization type, addition type, and magnification type, respectively. Checklist methods were continuously presented even while increasing and decreasing according to the year and season. This showed that it was highly possible for checklist methods to be continuously applied in future trench coat designs. Generally, a high frequency of appearance was shown in 2010 and during the F/W season. According to the development direction of future trench coat designs applied with the checklist method, it is predicted that the modification type and the elimination type (which have generally displayed high appearance frequency) will be continuously magnified in the future. In particular, it is expected modifications in structural details (which have showed an upward trend in 2011) will be further magnified.

There are many ways to know the social and cultural level of each country. Among them, a museum are not only the best place to understand the history, the life style and the culture level. The most important constituent, which museum architecture has, are visitors, exhibition and communication between visitors. Exhibition space composition is the one of important things in museum architecture, and it's essential to show an intent of exhibition to visitors. This thesis has the purpose to provide the basic material through analyzing exhibition space composition and exhibition method of the theme museum and understanding the relativity of them so that the new theme museums can be designed in the Tight direction. So I chose the independence museum that opened within recent 10 years, finally middle & small size's theme museum were selected. The results from the case study are as follow. Firstly, the exhibition space unit of basic type and center-hall enter type had a one-way for gateway and used the exhibition of three or four faces. The exhibition space unit of around tile center-hall type and guidance type had the separated gateway and used the exhibition of one or two faces. Secondly, the exhibition method of selected museums was divided into the wall face type and the island type. The exhibition method of two faces mainly used in guidance type caused complicated visitor circulation. In that case, it seemed to be good that two walls were used alternately. Thirdly, there were visual type, audio-visual type, handling type and experiential type in the method of exhibition. The former two types were used mostly, and the latter two types were rarely used. Fourthly, the wall face type was inefficient for exhibition because given walls were supposed to be used. Therefore, it was more effective to use the wall face type and the island type together.

In conventional transportation problem (TP), all the parameters are always certain. But, many of the real life situations in industry or organization, the parameters (supply, demand and cost) of the TP are not precise which are imprecise in nature in different factors like the market condition, variations in rates of diesel, traffic jams, weather in hilly areas, capacity of men and machine, long power cut, labourer's over time work, unexpected failures in machine, seasonal changes and many more. To counter these problems, depending on the nature of the parameters, the TP is classified into two categories namely type-2 and type-4 fuzzy transportation problems (FTPs) under uncertain environment and formulates the problem and utilizes the trapezoidal fuzzy number (TrFN) to solve the TP. The existing ranking procedure of Liou and Wang (1992) is used to transform the type-2 and type-4 FTPs into a crisp one so that the conventional method may be applied to solve the TP. Moreover, the solution procedure differs from TP to type-2 and type-4 FTPs in allocation step only. Therefore a simple and efficient method denoted by PSK (P. Senthil Kumar) method is proposed to obtain an optimal solution in terms of TrFNs. From this fuzzy solution, the decision maker (DM) can decide the level of acceptance for the transportation cost or profit. Thus, the major applications of fuzzy set theory are widely used in areas such as inventory control, communication network, aggregate planning, employment scheduling, and personnel assignment and so on.

Background: This study was aimed to determine the optimal vine induction method for growing of Korean schisandra (Schisandra chinensis), by comparing plant growth and fruit yields between plants grown with either fence-type (U-type) or A-type induction. Methods and Results: Plants were transplanted on August 17, 2014, and the plant height, stem node number and weight were measured every two weeks, six times from June 17, 2016. The plant height, stem node number, and leaf length and width were higher with the A-type than with the U-type induction, by approximately 37.0%, 49.1%, 27.6%, and 12.7%, respectively. Although there was no significant difference between the photosynthesis rates of plants grown with the two vine induction method, the leaf area and leaf number per plant were higher in the plants grown with the A-type than the U-type, by approximately 23.7% and 46.0%, respectively. The number of green-color pixels, in a defined area of digital camera images of creeper leaves from the inducted vines, was significantly higher in the plants grown with the A-type than the U-type. The number of fruit clusters per plant was approximately 26 and 36, under the U-type and A-type, respectively. A two fold higher total fruit weight per plant was observed in the plants grown under the A-type (250 g/plant) than the U-type (120 g/plant). Conclusions: The A-type vine induction method is optimal for cultivation of Korean schisandra.

This paper presents a method to estimate subpixel accuracy motion vectors using a mathermatical model withoug interpolation. the proposed method decides the coefficients of mathematical model, which represents the motion vector which is achieved by full search. And then the proposed method estimates subpixel accuracy motion vector from achieved mathematical model. Step by step mathematical models such as type 1, type 2, type 3, modified bype 2, modified type 3, and Partial Interpolation type 3 are presented. In type 1, quadratic polynomial, which has 9 unknown coefficients and models the 3by 3 pixel plane, is used to get the subpixel accuracy motion vectors by inverse matrix solution. In type 2 and 3, each quadratic polynomial which is simplified from type 1 has 5 and 6 unknown coefficients and is used by least square solution. Modified type 2 and modified type 3 are enhanced models by weighting only 5 pixels out of 9. P.I. type 3 is more accurate method by partial interpolation around subpixel which isachieved by type 3. LThese simulation results show that the more delicate model has the better performance and modified models which are simplified have excellent performance with reduced computational complexity.
