The academic library has the ideal environment as a facilitator of knowledge creation, as a space where researchers can collaborate and as a creation hub center on campus. Recently, based on the 4th Industrial Revolution and creative theories, the maker space is gradually being introduced into academic libraries in foreign countries. Maker Space of the academic library is the best place to discover new knowledge and interests, practice, and interdisciplinary education. In this study, we propose a plan to introduce the maker space of domestic university libraries through case studies of domestic and overseas university and university libraries.

Up sizing of dye-sensitized solar cell(DSC) is the important technology to bring about commercialization of DSC. Several studies to obtain a stable large area DSC have been investigated in overseas laboratories, but have been hardly done in our country. In this study, up sizing technology of dye sensitized solar cells(DSCs) was investigated. We investigated low dark current materials for the current collecting grid. From the result, a new DSC module with metal grid was designed, and fabricated. For a new interconnection, both working and counter electrodes are alternately coupled on 10[cm]$\times$7[cm] substrate. We have achieved 68% of fill factor and photoelectric conversion efficiency of around 2.6% as the best results of new designed DSC structure.

This study analyzed competition in peak load plants between CCGT and GT instead of competition between base and peak load plants like in previous studies. In common overseas power markets, CCGT and GT claim certain market shares as peak load plants with the latter boasting a high utilization rate as reserve plants. In South Korea, however, there has been no introduction of GT in the market that opened in 2001 with no analysis cases of GT's economy as a peak load plant. The current power market of South Korea is run on the cost-based pool, which allows for no price spikes. Since the capacity payment criteria for compensations for missing money are set based on GT generators, the power market uses GT generators as marginal plants. The purposes of this study were to analyze the competitive edge of GT generators as peak load plants in the domestic power market of South Korea and identify the causes of GT's failure in market entry, thus assessing the adequacy of market signals in the domestic power market.

Development of Moon Explorer-1 (orbiter) is supposed to be commenced in 2017 and launched in 2020. In case of Moon Explorer-2 (lander), it would be slated to start in 2021 and launch in 2025. For this reason it is taken for granted to investigate a fundamental propulsion system for a Moon Explorer. In this paper conceptual feasibility and comparison studies are proposed for the propulsion system applicable to a Moon Explorer. Availability of monopropellant/bipropellant/electric propulsion system is compared and analysed as well with precedents overseas. As a result possible candidates for a Moon Explorer propulsion system are suggested.

The purpose this study is to develop indicators that measure the healthy housing condition of multi-family housing. The major findings are as follow: first, healthy housing was defined by physical, mental, social, and management aspects and proposed the conceptual model of hierarchy structure of evaluation of healthy housing by literature reviews. Second, evaluating items were selected based on literature reviews of existing indicators and preceding studies about both domestic and overseas multi-family housing. The evaluating indicators were identified as a total of 87 evaluating items which were composed of four dimensions and 16 attributes on the basis of the conceptual model. They cover comprehensive scope of the multi-family housing such as unit, building, complex, and site. Third, as the measurement, the 5-point ordinal scale measure was suggested. The evaluating measurement including measure standards, measure methods, and measure contents were developed by each evaluating items. Lastly, the weighting of evaluating indicators was developed by AHP method conducted by survey of an expert group. Items were identified as high contributors or low contributors. The weighting of these items could suggest several evaluations according to the situation. The level of healthy housing condition may be evaluated by both total evaluation and a specific field of evaluation.

The purpose of this study was to examine the characteristics of conspicuous kids fashion and its intrinsic meaning as the popular trends of luxury product consumption expand into the area of kids' fashion. For methodologies, literature study was conducted along with empirical study. The literature study was based on various literatures and preceding studies, including books. The empirical materials used the internet photos, overseas kids fashion magazines, and free newspapers available on the basis of membership targeting the upper class. Conspicuous kids fashion refers to imported luxury kids brands, which signify higher status of the wearer due to the high prices and high quality. These brands were thrust into limelight amid the Wanna-Be Phenomenon, which resulted from the emergence of kids' fashion icons. Imported luxury brands launched the products in the form of brand line extensions. It promoted exhibition of vicarious consumption to show off the wealth and social prestige of parents. It came into prominence due to emotional consumption among kitty moms. Moreover, this study examined the intrinsic meaning of conspicuous kids fashion. The results showed components of conspicuous kids fashion, which was classified into the emphasis on outward appearance, consumption for vicarious satisfaction, inheritance of cultural capital, and network configuration.

The use of non-bearing light weight wall has increased recently due to the increase of high-rise buildings and supply of long-life housing. Light weight wall has advantages such as reducing the self-weight of the building, convenience in installation, and shortening construction period, however, must have a sufficient strength to external force. This study standardized the impact resistance test method for light weight walls by using the actual impact load obtained through load analysis test in previous studies. The impact resistance test method was divided into the test method that uses soft body and the one that uses hard body. The size of specimen was set up as height 2.4m and width 3.0m. The size and shape of the body followed those used in BS 5234-2 and so on for the compatibility with the test method used overseas. The judgment criteria for impact resistance based on test results were not defined uniformly as the assessment of functional damage can vary depending on the type of material, structural method, purpose of wall, and so on even when the same impact load was applied.

Although the Act on the Prevention of Light Pollution Due to Artificial Lighting has been enforced since 2013, the area of advertisement lighting has made slow progress in solving the problems of light pollution. This paper first investigated institutional problems by analyzing domestic laws and regulations relating to the light pollution of advertisement lighting, and investigated and analyzed methods for reducing light pollution that were applied in overseas countries. Then, problems of light pollution were analyzed by conducting a research on the actual status of advertisement lightings installed in South Korea and applying various methods for reducing light pollution, and advertisement lighting using LED was recommended. As a method for reducing light pollution that can be applied to the process of manufacturing channel letter-type advertisement lights, power consumption per unit area ($W/m^2$) was proposed, and $100W/m^2$ was recommended as a value currently suitable for South Korea.
