This thesis is to analyze and assess a new refuse collection system that was based on the term of discharge based quantity and collection of refuse from the beginning on January 1, 1995.In the case study for the refuse collection policy of metropolitan Taegu city based on the year of operation, ie, before 1994, after 1995 and as of 1998, the refuse collection policy analyzed from current position and actual condition. The results of analysis as follows. In case of discharged refuse quantity was show 20.4% reduction than the operation was begun and more 5.8% reduction as of 1998.Under the operation of the refuse collection system, therefore, management of refuse and garbage, the reduction of discharged refuse, activation of refuse collection, Recycling and expansion of financial self-reliance increased efficiency of refuse collection system. In the conclusion, more perfect refuse collection system should be developed of implemented in the near future.

The soybean [Glycine max (L.) Merr.] is one of the most important crop resources worldwide as food and forage. It is also important and valuable that to hold crop resources to have high genetic diversities. Recently, a core collection has been constructed in many plants to preserve the genetic resources of various plants. A core collection is small population to represent the genetic diversity of the total collection, and is of strategic importance as they allow the use of a small part of a germplasm collection that is representative of the total collection. Here, we developed the core collection consisting of 816 accessions by using approximately 180,000 (180K) single nucleotide polymorphisms (SNPs) developed in previous study. In addition, we performed genetic diversity and population structure analysis to construct the core collection from entire 4,392 collections. there were excluded sample call rates less than 93% and duplicated samples more than 99.9% according to genotype analysis using 180K SNPs from entire collections. Furthermore, we were also excluded natural hybrid resources which Glycine max and Glycine soja are mixed in half through population structure analysis. As a result, we are constructed the core collection of genetic diversity that reflects 99% of the entire collections, including 430 cultivated soybeans (Glycine max) and 386 wild soybeans (Glycine soja). The core collection developed in this study should be to provide useful materials for both soybean breeding programs and genome-wide association studies.

This study investigates the analysis on the acceptance of Foreign Fashion trends in Korean Fashion Collection by collections, years, season, and designers. The purpose of this study is Korean collection's degree to adopt and receive foreign collections, by comparative analysis of design features between Seoul and foreign collections. For such purpose, from 2006 S/S to 2011 F/W, 5185 pictures were collected from designer's photos of Seoul, Paris, Milan, NY, and London collections. The content analysis and statistical analysis using SPSS will be conducted for data analysis. The results of the research are as follows. First, regarding the design features, square-form silhouette, achromatic colors, and none pattern were presented as well. Second, there were significant differences in the design characteristics of each year. Particularly, in 2008, X-form silhouette, Yellow and Green color, and flower pattern were emphasized. Third, the design features by season were significant differences. In S/S season, square-form and X-form silhouette, achromatic colors of white and gray color, none pattern were evident while in F/W season, square-form Silhouette, achromatic colors of black and gray, and none pattern were emphasized. Fourth, the design features by designer are as follows. In terms of form, Seoul collection was influenced by Paris collection. In terms of colors, it was influenced by NY and London collections.

The transport of charged particles in electrostatic precipitator is investigated by Eulerian numerical analysis. Collection efficiencies are calculated using various combinations of the assumptions about flow field, turbulent diffusivity and boundary condition at collecting electrode. The characteristics of calculated collection efficiencies are compared with the trends of published experimental results. It is found that the collection efficiency for the case using nonuniform turbulent flow field, nonuniform turbulent diffusivity and zero concentration boundary condition at collecting electrode is the most suitable for the prediction of collection efficiency of electrostatic precipitator.

The purpose of this study was to compare and analyze the Chinese robe styles of the Paris and Beijing collections from 2014 to 2018 to find the differences between the expressions of European and Chinese designers on the Chinese robe style. The methods of research were a literature review to derive the design analysis items of Chinese robe styles, and a case analysis. The results are as follows. First, both the Paris and Beijing collections showed an increase in use of Chinese robe styles year by year. Second, in the Paris collection, designs using qipao styles from the Republic of China era appeared the most among the robe styles of various Chinese dynasties. Qipao style appeared the most in the Beijing collection too, but the robe styles from the era of Pre-Qin, Qin, Han, Song, Ming, and Qing dynasties appeared more often than in the Paris collection. Third, in the comparison of silhouette type, there were mostly X-type silhouettes in the Paris collection and A-type silhouettes in the Beijing collection. As for neckline and sleeve type, both collections showed stand collars and tube sleeves. Fourth, in color comparison, there were mostly red-based colors in the Paris collection and blue-based colors in the Beijing collection. Fifth, in the comparison of pattern type, there were the mostly plant motif patterns in the Paris collection, and complex patterns in the Beijing collection. In conclusion, it was confirmed that the Chinese robe styles of the Paris Collection expressed a design fused with various styles due to the tendency to respect the diversity of various cultures and of the Beijing Collection emphasized the beauty and ethnicity of traditional Chinese clothing.

In this paper, we propose a simplified tag collection algorithm to improve the performance of ISO / IEC 18000-7, the standard of active RFID systems. In the proposed algorithm, the collection command is modified to include the result of the listening period response from the previous round. The tag, which has received the collection command, checks whether the slot to which it has responded is collided, transmits additional data to its data slot without a point-to-point read command and sleep command, and transitions to the sleep mode. The collection round in the standard consists of a series of collection commands, collection responses, read commands, read responses, and sleep commands. On the other hand, in the proposed tag collection algorithm, one collection round consists only of a collection command and a collection response. As a result of performance analysis, it can be seen that the proposed technique shows superior performance compared to the standard.

This study is conducted to get current state of data collection and utilization of the trees damaged by pine wilt disease, and to efficiently collect and utilize of the trees damaged by the pine wilt disease and abandoned fumigation-treated trees at forecasts. The method to control pine wilt disease damaged area is mostly fumigation treatment system, and there is no collection and utilization of damaged trees because of absence of efficient collection system, lack of collection cost, and absence of policy, etc. A survey is conducted that asked about the satisfaction degree for the trees damaged by pine wilt disease collection and use divided into 6 topics. It was positively recognized that the need and problem of the trees damaged by pine wilt disease, and results and satisfaction of forestry mechanization while it was mostly negatively recognized that the policy satisfaction for prevention and collection, satisfaction of collection and use, collection and forestry mechanization, and satisfaction of foundation equipment for forestry mechanization, etc. As a result of path analysis, it is necessary to promote a high-tech forestry mechanization to improve satisfaction level of results and satisfaction of forestry mechanization for the trees damaged by pine wilt disease collection and utilization, it is also need to make an effort in various ways for improve satisfaction level of satisfaction of collection and utilization.
