  • In July and October of this year, the government announced the 'Green new deal plan within the Korean new deal policy' and 'Strategies for proliferation of future vehicles and market preoccupation'. And, in response to changes in the global climate agreement, it has decided to expand green mobility such as electric vehicles and hydrogen electric vehicles with the aim of a "net-zero" society. Accordingly, the goal is to build 310 hydrogen refueling stations along with the supply of 60,000 hydrogen vehicles in 2022, and the hydrogen infrastructure is being expanded. however, it is difficult to secure hydrogen infrastructure due to expensive construction costs and difficulty the selection of a site. In Korea, it is possible to build a mobile hydrogen station according to the safety standards covering special case of the Ministry of Industry. Since the mobile hydrogen station can be charged while moving between authorized place, it has the advantage of being able to meet a large number of demands with only one hydrogen refueling station, so it is proposed as a model suitable for the early market of hydrogen infrastructure. This study demonstrates the establishment of a hydrogen refueling station by deriving a virtual accident scenario for leakage and catastrupture for each facility for the risk factors in a mobile hydrogen station, and performing a quantitative risk assessment through the derived scenario. Through the virtual accident scenario, direction of demonstration and implications for the construction of a mobile hydrogen refueling station were derived.

  • As the use of new and renewable energy is one of the ways by which the exhaustion of fossil fuels and the other existing environmental problems can be addressed, a policy of spreading information regarding it and of conducting R&D related to it is currently being implemented in advanced countries. In the construction field, the concept of "green building" was born, and the application of this concept has increased, with the end in view of achieving energy savings, resource savings, and recycling, and of conserving the natural environment. In this context, the government of Korea amended the "Law on the Development, Use, and Promotion of New and Recycled Energy" in 2004, which contains 11 provisions related to new and renewable energy and their sources, including solar and geothermal energy as well as sunlight, water, rainfall, and organisms. Since solar-energy should be used instead of fossil fuels by converting sunlight directly into electricity, many researches on this subject are in progress. There are few researches, however, employing the economic approach to the subject. Thus, in this study, an economic assessment of the solar-energy system was conducted using both life cycle cost (LCC) analysis and sensitivity analysis. The results of the LCC analysis show that the solar-energy system will become economically better than the fossil fuel system after 16 years, although the initial construction cost of the solar-energy system is higher than that of the fossil fuel system. The results of this study are expected to be used in selecting an eco-friendly and economical solar-energy system when the construction of a green building is planned.

  • The purpose of this study is to examine the color characteristics of menswear in different cities, focusing on the Paris, Milan, New York, Tokyo, and London collections. To answer the research question, the sampled colors were classified according to their hues and tones for frequency analysis and cross-analysis. The results are as follows: 'Red', which appeared frequently in the S/S and F/W seasons, was a core color in menswear design, and regardless of the season, 'blackish tones' were most commonly used. The cross-analysis uncovered a significant difference in the trends of hues in the F/W season between the cities. The colors that were more frequently used among the cities were as follows: 'blue-green' in the Paris collection, 'blue' and 'purple' in the Milan collection, 'purple' and 'purple-blue' in the London collection, 'yellow' in the New York collection, and 'red' and 'green' in the Tokyo collection. This study illustrates the significance of the F/W season's use of colors in menswear design and discovered through analysis that hues, rather than tones, were used to express individuality. These results are expected to be used as basic data for the analysis of menswear design trends.

  • The purpose of this study was to examine the importance of eco-friendly design elements related to residential space by residents and what element they prefer. To achieve this, 18 eco-friendly design elements related to residential space were selected from the Green Building Certification Criteria and the relevant research papers. These elements were categorized into four areas; the ecological environment area (4 elements), the indoor environmental climate one (4 elements), the energy and resource saving one (6 ones), and the material one(4 ones). On the base of these 18 elements, the importance degree of each element was examined by using 5-point Likert scale. The subjects were 299 housewives living in apartment houses in Jangyu new town, Gimhae. The subjects perceived strongly the importance of eco-friendly design elements, but many of them did not know about Green Building Certification Criteria. Overall importance of 18 elements by the residents was very high. Also, the indoor environmental climate area was considered as the most important one, followed by the energy and resource saving area, the material area, and the ecological environment one.

  • Sj$\"{o}$gren's syndrome (SS) is an autoimmune disorder that affects the salivary glands, leading to xerostomia, and the lacrimal glands, resulting in xerophthalmia. Secondary SS is associated with other autoimmune disorders such as systemic rheumatic diseases and systemic lupus erythematosis (SLE), which can affect multiple organs, including the epidermis. Recent studies have demonstrated that green tea polyphenols (GTPs) possess both anti-inflammatory and anti-apoptotic properties in normal human cells. Epidemiological evidence has indicated that, in comparison to the United States, the incidence of SS, clinical xerostomia and lupus is considerably lower in China and Japan, the two leading green tea-consuming countries. Thus, GTPs might be responsible, in part, for geographical differences in the incidence of xerostomia by reducing the initiation or severity of SS and lupus. Consistent with this, molecular, cellular and animal studies indicate that GTPs could provide protective effects against autoimmune reactions in salivary glands and skin. Therefore, salivary tissues and epidermal keratinocytes could be primary targets for novel therapies using GTPs. This review article evaluates the currently available research data on GTPs, focusing on their potential application in the treatment of the oral manifestations of SS and skin manifestations of SLE.

  • Oscillating wave amplitude in a bottom-mounted owe chamber designed for wave energy converter is investigated by applying characteristic wave conditions in Korean coastal water. The effects of shape parameters of OWC chamber in a view of wave energy absorbing capability are analyzed. Both experimental and numerical approaches are adopted and their results are compared to optimize the shape parameters which can result in a maximum power production under given wave distribution. The experiment was carried out in a wave flume under 2-D assumption of OWC chamber. In numerical scheme, the potential problem inside the chamber is solved by use of the Green integral equation associated with the Rankine Green function, while outer problem with the Kelvin Green function taking account of fluctuating air pressure in the chamber. Air duct diameter, chamber width, and submerged depths of front skirt and back wall of chamber changes the magnitude and peak frequency of wave absorption significantly.

  • Waste glass disposal causes environmental problems in the cities. To find a suitable green environmental solution for this problem low cost adsorbent in this study was prepared from waste glass. An effective new green adsorbent was synthesized by hydrothermal treatment of waste glass (WG), followed by acidic activation of its surface by HCl (WGP). The prepared adsorbent was characterized by scanning electron microscopy (SEM), X-ray fluorescence (XRF), X-ray diffraction (XRD), and BET surface measurement. The developed adsorbent was used for the removal of heavy metals (Cd, Cu, Fe, Pb and Zn) from well water. Batch experiments were conducted to test the ability of the prepared adsorbent for the removal of Cd, Cu, Fe, Pb and Zn from well water. The experiments of the heavy metals adsorption by adsorbent (WGP) were performed at different metal ion concentrations, solution pH, adsorbent dosage and contact time. The Langmuir and Freundlich adsorption isotherms and kinetic models were used to verify the adsorption performance. The results indicated high removal efficiencies (99-100%) for all the studied heavy metals at pH 7 at constant contact time of 2 h. The data obtained from adsorption isotherms of metal ions at different time fitted well to linear form of the Langmuir sorption equation, and pseudo-second-order kinetic model. Application of the resulted conditions on well water demonstrated that the modified waste glass adsorbent successfully adsorbed heavy metals (Cd, Cu, Fe, Pb and Zn) from well water.
