  • It is widely known that agricultural plastic waste incineration by farmers may cause big forest fire or fine dust in rural areas. Hence, how to increase the rate of collection and recycling of the agricultural plastic waste is of concern to policy makers especially for rural environment. The purpose of this study is to find the determinants of the collection rate of agricultural plastic waste. This study used the data from 'Research on Agricultural Waste' by the Korea Environment Corporation from year 2012 to 2015 for 163 regions. This study found that the compensation rate for collection, the frequency of collecting services, and the quality of waste are important to increase the collection rate. And the regions with more elderly and low income people are more likely to have higher collection rate. Finally, the chief producing regions that are specialized in a certain crop shows higher collection rate.

  • This study is to understand the current situation of the Seoul Collection and suggest market oriented strategies in order to establish a more effective fashion market. Three elements-time, form, and, place-were defined to analyse the dynamics of the collection and two factors-customer/competitor oriented information and information interaction among participants-were employed to evaluate the Seoul collection toward market orientation. The data were collected from the collection participants via an in-depth interview. The identified major market factors were: 1. Time-In order to create a desirable market, the opening time of the Seoul Collection needs to be rescheduled in accordance with the openings of other countries. Also the time must be suitable to the buyer's movement. 2. Product-Products which did not meet the needs of the market and their unrealistically high prices were two main factors that hindered sales. 3. Place-Although the place was a vital factor to the success of the collection, the facility was not fully a suitable location for buyers to place orders. Additionally, the analyzed data indicated the low market-oriented Seoul collection. Vital to elevating the Seoul Collection to meet the global standard, therefore, more practical research and merchandise planning should be arranged in advance.

  • Refuse collection, one of important elements in reverse logistics, is an activity rendering recyclables or wastes and moving them to some points where further treatment is required. Among various decisions in the collection activity, we focus on network design, which is the problem of locating collection points as well as allocating refuses at demand points to collection points while satisfying the capacity restriction at each collection point. Here, the collection point is the place where recyclables or wastes near the point are gathered, and locating the collection points is done by selecting them from a given set of potential sites. The objective is to minimize the sum of fixed costs to open collection points and transportation costs to move refuses from demand points to collection points. An integer programming model is developed to represent the problem mathematically and due to the complexity of the problem, two types of heuristics, one with simultaneous and the others with separate location and allocation, are suggested. Computational experiments were done on test problems up to 500 potential sites, and the results are reported. In particular, some heuristics gave near optimal solutions for small-size test problems, i.e., 2% gaps in average from the optimal solution values.

  • The purpose of this study is to bring out the most reasonable and feasible evaluation methods of research library collection in Korea. At the very outset, writer tried to define the purpose and the necessity of collection evaluation. Writer described a collection evaluation is to gain the data for decision making on selection policy, weeding and storage project, and explained it is one of the procedures of a collection development system operation of being explained as repeated three procedures through a collection development plan, an implimentation of the set plan(selection process) and a collection evaluation. Writer also pointed out the fact many libraries in Korea are apt to by pass or overlook this important process. Writer then defined the criteria of a collection evaluation as the measurement of the proportion of library holding's capability to meet users' demands and that of the degree of total collection's utilization. Writer introduced and analysed seven existing collection evaluation methods and concluded the method by a survey of users' needs and opinion and the method by a circulation survey are the most feasible and reasonable methods that can be applied. Writer also added that using above two evaluation methods together can enhance the effectiveness of collection evaluation.

  • The objective of this study was to determine the effect of administration of Prostaglandin $F_2{\alpha}$ ($PGF_2{\alpha}$) on semen collection training and semen characteristics in sexually inexperienced boars. Boars were moved individually to a semen collection pen and were trained to mount dummy sow. During the first and second semen collection secessions, 4 out of 17 boars and 4 out of remaining 13 boars allowed collection of semen. The 9 boars that failed semen collection from first 2 attempts received immediately 15 mg of $PGF_2{\alpha}$ i.m. (intramuscular injection) upon entering the collection pen for semen collection resulted in successful semen collection from all 9 boars. Total numbers of spermatozoa were higher in $PGF_2{\alpha}$ treated boars but there was no significant difference in % motility kinematics characteristics between control and $PGF_2{\alpha}$ treated groups during 72 hr period. Overall, administration of $PGF_2{\alpha}$ in sexually inexperienced boars increased the sex drive and facilitated the mounting activity to the dummy sow for semen collection.

  • 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.

  • Particle collection characteristics of the MOUDI cascade impactor has been studied for coarse particles in the range of 2 to 20$mu extrm{m}$ in aerodynamic diameter. A vibrating orifice aerosol generator was empolyed to generate monodisperse test aerosols. The oleic acid and sodium chloride(NaCl) particles were used as test aerosols. Aluminum foil and Teflon filter were selected as impaction media. The sampling flow rate was changed from 25 to 35L/min. Particle collection efficiency for single stage was examined for liquid particles. The stage response was obtained experimentally for the cascade impactor composed of three stages and a backup filter. The results showed that most of particle collection efficiencies measured in this work are similar to the efficiency curves obtained by Marple et al.(1991). For particles less than cut-off size of the stage, the collection efficiencies of solid particles are similar to those of loquid particles. However, the collection efficiency of solid particles decreases with mereasing particle diameter for the particles greater than the actual cut-off size of the impactor. The particle collection efficiency increases with increasing sampling flow rate at the same particel size. However, the collection efficiency curves seem not to be greatly shifted with the flow rate. The stage responses obtained by direct measurements in this work are in good agreement with those derived from the collection efficiency curves for single stage.

  • This study is an attempt at developing an organizational model for collection development a n.0, pplicable to Korean university libraries at their present stage of development. An emphasis is placed on the discussion of the 'subject a n.0, pproach' as compared to 'functional a n.0, pproach' in collection development work. The case history of Pusan National University Library is extensively used. The proposed collection development model consists of the following elements : - To form a collection development team and to place under the team leader subject bibliographers as follows: Bibliographer for Serials Bibliographer for Humanities Bibliographer for Social Sciences Bibliographer for Sciences and Technologies - Collection development team could operate as a separate department or as part of other departments, i. e., Deputy Director's office, Acquisitions and Processing Department, or Resources Management Department. - Collection development team takes up the responsibility for policyrelated collection work, i. e., budget allocation, evaluation of existing collection, building core collection, preservation, weeding and cooperation. - Designated certified librarians located at the(planned) subject libraries take up the responsibility for selection. Subject bibliographers cooperate with selection librarians and coordinate their work. - Certified librarians at the Acquisitions and Processing Department are assigned subject areas. They operate as acquisitions librarian and processing librarian simultaneously with their assigned subject materials.

  • This paper evaluated the collection development of the Korean collection at the A university over the several decade. Compared against the ACRL standard Formula A, the result demonstrated that the Korean library collection is still needed to increase Korean collection to support Korean-related program and Korean community in the area. When we share western language materials in the library as the same area studies resources, we can evaluate Korean studies collection as Level B. Comparison with similar institutions (ARL comparisons) shows that the collection is the middle among 15 universities which provide Korean programs. The situation for Korean resources at the A university is needed to get more support from Korean institutes and Korean societies to keep up with the Korean collection for academics and regional community users as well.
