As Korea becomes a multi-cultural society, Korean government ministries are enforcing various multi-cultural services. Especially, Ministry of Culture, Sports and Tourism, which is in charge of public libraries, is operating multi-cultural services for cultural diversity. The trends in the research on the multi-cultural services in public libraries, however, are rather on adaptation of the multi-cultural people in Korea than on the cultural diversity. In this exploratory study, we investigated the perception of local residences on multi-cultural library services with several in-depth interviews with the local residences not only for the adaptation but also for the cultural diversity. The results shows that they tended to regard public libraries as an institution of local life-long education, and then they think public libraries can take a role for coping with social adaptation and prevention of social problems in terms of multi-cultural population. Based on the results, public libraries would better consider to inform their roles in this multi-cultural society to their local residences based not only on adaptation but also on cultural diversity. For this, the libraries would develop programs, in which both multi-cultural and non-multi-cultural people can be participated, to encourage communication between them.

The growing stocks of young forests that are less than10 years of age have been excluded from the Korean forest resource statistics, despite the existence of standing trees; however, sustainable forest management and carbon removals in the forestry section require complete information regarding forest resources. This study developed a method to estimate the growing stocks for young forests from National Forest Inventory (NFI) data. After reviewing previous research on growth characteristics for young forests, we conducted stem analysis of major species, and examined stand characteristics by site index, based on real yield tables. Our statistical analysis results showed that there were few standing trees with diameters at breast height (DBH) above 6 cm in young stands, and that it would have taken 12 years, on average, to reach 6 cm DBH. This suggests that mean tree height by diameter should be assessed at the root, in order to assess growing stocks for young stands through the NFI. Moreover, the database system should be improved to differentiate tree species, since diverse shrubs, including trees, have been surveyed.

This study was conducted to examine the recent developments in timber certification schemes at global level such as FSC certification and ISO 14001 system and to analyze their potential impacts on the Korean forest products trade. Data and information on standards and procedure of timber certification and certified forest lands were collected from relevant papers, statistics and reports published by regional and international organizations. In order to analyze the impacts on the Korean forest products trade, questionnaire survey to the affected parties was conducted on acknowledge of key words relating to environment and trade and on the additional amount of willingness to pay for a labeled timber from environmentally sound and sustainably managed forests. Quantities of certified timbers supplied would continue to increase due to lots of timber certification schemes developed and implemented at national, regional and global levels and growing interests in certification from many countries. Demand for certified timbers, however, is far from clear at this stage. The deciding factor would be consumer reaction to the certified products. In the short run, the timber certification would have a little impacts on forest products imports into Korean markets since domestic purchasers do not have much interests in environment related trade measures and their willingness to pay price premiums for certified timbers is not high. However, it could be expected that timber certification has negative impacts on exports of forest products, such as flooring and plywood, to developed European markets where timber certification is used as a trade barrier.

The fatigue characteristics of glass fiber reinforced plastic (GFRP) composites were studied under repeated loads using the finite element method (FEM). To realize the material characteristics of GFRP composites, Digimat, a mean-field homogenization tool, was employed. Additionally, the micro-structures and material models of GFRP composites were defined with it to predict the fatigue behavior of composites more realistically. Specifically, the fatigue characteristics of polybutylene terephthalate with short fiber fractions of 30wt% were investigated with respect to fiber orientation, stress ratio, and thickness. The injection analysis was conducted using Moldflow software to obtain the information on fiber orientations. It was mapped over FEM concerned with fatigue specimens. LS-DYNA, a typical finite element commercial software, was used in the coupled analysis of Digimat to calculate the stress amplitude of composites. FEMFAT software consisting of various numerical material models was used to predict the fatigue life. The results of coupled analysis of linear and nonlinear material models of Digimat were analyzed to identify the fatigue characteristics of GFRP composites using FEMFAT. Neuber's rule was applied to the linear material model to analyze the fatigue behavior in LCF regimen. Additionally, to evaluate the morphological and mechanical structure of GFRP composites, the coupled and fatigue analysis were conducted in terms of thickness.

Finite element method (FEM) is utilized in the development of products to realistically analyze and predict the mechanical behavior of materials in various fields. However, the approach based on the numerical analysis of glass fiber reinforced plastic (GFRP) composites, for which the fiber orientation and strain rate affect the mechanical properties, has proven to be challenging. The purpose of this study is to define and evaluate the mechanical properties of glass fiber reinforced plastic composites using the numerical analysis models of Digimat, a linear, nonlinear multi-scale modeling program for various composite materials such as polymers, rubber, metal, etc. In addition, the aim is to predict the behavior of realistic polymeric composites. In this regard, the tensile properties according to the fiber orientation and strain rate of polybutylene terephthalate (PBT) with short fiber weight fractions of 30wt% among various polymers were investigated using references. Information on the fiber orientation was calculated based on injection analysis using Moldflow software, and was utilized in the finite element model for tensile specimens via a mapping process. LS-Dyna, an explicit commercial finite element code, was used for coupled analysis using Digimat to study the tensile properties of composites according to the fiber orientation and strain rate of glass fibers. In addition, the drawbacks and advantages of LS-DYNA's various anisotropic material models were compared and evaluated for the analysis of glass fiber reinforced plastic composites.

A primary aspect of low impact development (LID) design that affects performance efficiency, maintenance frequency, and lifespan of the facility is the type of filter media as well as the arrangement or media profile. Several LID guidelines providing media specifications are currently available and numerous studies have been published presenting the effectiveness of these systems. While some results are similar and consistent, some of them still varies and only a few focuses on the effect of filter media type and arrangement on system performance. This creates a certain level of uncertainty when it comes to filter media selection and design. In this review, a synthesis of filter media specifications from several LID design guidelines are presented and relevant results from different laboratory and field studies are highlighted. The LID systems are first classified as infiltration or non-infiltration structures, and vegetated or non-vegetated structures. Typical profiles of the media according to classification are shown including the different layers, materials, and depth. In addition, results from previous studies regarding the effect of filter media characteristics on hydraulic and hydrologic functions as well as pollutant removal are compared. Other considerations such as organic media leaching, clogging, media washing, and handling during construction were also briefly discussed. This review aims to provide a general guideline that can contribute to proper media selection and design for structural LIDs. In addition, it also identifies opportunities for future research.

In this study, an investigation has been made on the status of the issuance of librarian qualification, the status of operating Subject specialized librarians at home and abroad, the status of professional manpower of the similar cultural facilities, and their recruitment method, based on which an attempt has been made to propose a way to nurture the Subject specialized librarians. First, I propose a method for training Subject specialized librarians through a regular curriculum and a retraining process, while suggest the ways to nurture the Subject specialized librarians from undergraduate and also nurture the existing librarians to become the Subject specialized librarians. Second, the basic qualification of the Subject specialized librarians must have a career of more than 3 years in a specific subject area with a master's degree or higher, and in order to have a subject area background, it is proposed that a bachelor's degree or a master's degree must absolutely be acquired in the corresponding subject area. Third, in order to improve the treatment of such Subject specialized librarians, the Subject specialized librarians in the administrative service group could be organized into a research librarian (or library and information science) series and types as a subordinate literary series under the researcher position. That is, it is proposed to differentiate the librarians and the Subject specialized librarians by reorganizing series and types of the Subject specialized librarians while maintaining the current librarian series.
