This study compared and analyzed the trends of wellness-related tourism polices in Japan, which have policy similarities with Korea, through related literature research and online interview surveys amid growing demand for wellness tourism in Korea's wellness tourism policy implications. According to the survey, wellness tourism-related concepts do not differ particularly between Korea and Japan, and the use of health tourism or wellness tourism concepts is more common in Japan than healing tourism. Wellness tourism policy is analyzed to be more systematic in Japan in the areas of policy principal agent's flexibility, policy efficiency, related certification, and human resource development, and Korea in the driving force and institutional maintenance of policy. It was judged that Korea needs to establish a wellness tourism consultative body, such as the case of Japan, and improve efficiency through systematic certification of wellness tourism and qualitative management of related manpower. In order to industrialize wellness tourism, it is necessary to increase the healing effectiveness and product value of wellness tourism by organically linking wellness resources specialized by region, and to conduct in-depth analysis of the direction and strategies of wellness tourism policies in preparation for the post-Corona(COVID-19) Era and an empirical study of tourism sites.

High-temperature polymer electrolyte membrane fuel cell (HT-PEMFC) has been studied as an alternative to low-temperature PEMFC due to its fast activation of electrodes and high resistance to electrode poisoning by carbon monoxide. It is highly required to develop stable PEMs operating at high temperatures even doped by ion-conducting materials for the development of high-performance and durable HT-PEMFC systems. A number of studies have been conducted to develop polybenzimidazole (PBI)-based PEMs for applications in HT-PEMFC due to their high interaction with doped ion-conducting materials and outstanding thermomechanical stability under high-temperature operation. This review focused on the development of PBI-based PEMs showing high performance and durability. Firstly, the characteristic behavior of PBI-based PEMs doped with various ion-conducting materials including phosphoric acid was systematically investigated. And then, a comparison of the physicochemical properties of the PEMs according to the different membrane manufacturing processes was conducted. Secondly, the incorporation of porous polytetrafluoroethylene substrate and/or inorganic composites to PBI matrix to improve the membrane performances was studied. Finally, the construction of cross-linked structures into PBI-based PEM systems by polymer blending method was introduced to improve the PEM properties.

The effects of climatic changes owing to urbanization, geographical and topographical conditions on annual and monthly FAO Penman-Monteith (FAO P-M) reference evapotranspiration, and energy and aerodynamic terms of FAO P-M reference evapotranspiration were studied. In this study, 21 climatological stations were selected. The statistical methods applied for trend analysis are Spearman rank test, Sen's test, linear regression analysis and analysis of actual variation ratio. Furthermore, the cluster analysis was applied to cluster 21 study stations by considering the geographical and topographical characteristics of study area. The study results indicate that urbanization affects the trend and amount of FAO P-M reference evapotranspiration, energy term and aerodynamic term; however, the result of Sen's test indicates that urbanization does not significantly affect the magnitude of trend (Sen's slope). The energy term increased at study stations located in coastal area; however, decreased at study stations located in inland area. The topographical slope of study area did not significantly influence on the trend of energy term. The aerodynamic term increased in both coastal area and inland area, indicating much significantly increasing trend in inland area, and it was also affected by the topographical slope of the study area.

The rapidly changing security environment and technological innovations of the 21st century present new challenges to military organizations. Particularly, as the MZ generation, comprised of Millennials (born 1981-1996) and Generation Z (born 1997-2012), emerges as the primary workforce in the military, traditional military personnel management methods are being called into question. The MZ generation, as digital natives, are technologically proficient, prioritize personal growth and quality of life, and prefer horizontal communication and participation. The purpose of this study is to reestablish talent acquisition and retention strategies for military organizations, considering the characteristics and demands of the MZ generation. To this end, we analyzed advanced talent management techniques from the corporate sector and explored ways to apply them to the unique context of military organizations. Additionally, by examining the current status and challenges of the Korean military, we attempted a balanced approach that considers both global trends and Korea's specific circumstances. The research results suggest various strategies including career development programs, cultural innovation, improvement of reward systems, participatory decision-making, enhancement of digital competencies, and creation of flexible work environments. These strategies are expected to improve the efficiency and competitiveness of military organizations while simultaneously enhancing job satisfaction and organizational commitment among MZ generation service members.

With the changing of social needs and paradigms, citizens are concerned about aesthetic and cultural community gardens from productive urban farms in Korea. It is still difficult, however, to cultivate a beautiful garden with a community to design, install and manage it. Therefore, this study analyzed the community garden design guidelines of other countries to derive the characteristics and implications. The research method analyzed six guidelines for community garden design in the UK, Canada, the USA, Australia and Japan. As a result of the study, most community garden design guidelines are opened freely via on-line service. The guidelines are composed with chronological processes such as intro, site selection, design, construction and maintenance. The introduction section treats definition, purpose, meaning, efficiency and success factors for community gardens. Site selection emphasizes site conditions (soil, light, shadow, water, etc.), landholding and insurance. The design section, however, lacks adequate drawings and case images. These guidelines offer little explanation with few illustrations and sentences. Construction sections explain about plantings, facilities, expense and details. The maintenance guidelines of community gardens contain how to control members, funding, harvesting, pests and plants. In addition, some guidelines include vandalism, organic cultivation methods, recording and advertisement. Lastly, the appendix contains a variety of checklists, administrative documents, guidelines, drawings, and contacts. This study will help understand the trends and characteristics of overseas community gardens design guidelines so as to also supply directions for guidelines to be introduced in Korea.

Fashion is one of the characteristics which represents the comtemporary sociocultural signifiant. A style that a certain stream of fashion brings is not just limited in fragmentary tendencies and fads. That can be a code to communicate and function as a medium in itself. Music has been displaying it's power to fashion while fashion has been exercising it's influence over the music. There is an inseparable relationship between music and fashion in terms of expressing our images of the world: fashion delivers them through visuality and music does it by sound. Both fashion and music are reflecting our society as well as they are influencing on sociocultural aspects generally. Whenever music has been changed new youth culture has been made and this culture has been expanded with forming some distinct fashion trends. The study focuses on identifying the relations between pop music and fashion styles which are occupying positions firmly on the bases of youth culture through analysing the relations between the fashion styles and music genres which are used in sub-culture groups to express their own identities and consciousness from a point of semiotics. In conclusion, subculture is the exit of their escaping from the compelling inconsistency cause by the condition of people's life and the way for them to solve through cultural sublimating for themselves. People come up with distinctive style of music and fashion to express their resistant signifie in their symbolic way. In addition, a particular music trend has much to do with a contemporary fashion style. In the relationship between music and fashion, there have been the subtle mechanism to boost and influence and some crucial similarity each other to signify inner values of the times. This study lets us realize that fashion is not only a popular style of clothes, hair, etc. at a particular time or place but also a medium to communicate and to guarantee polysemous identity by functioning as a flexible tool to exchange contemporary sociocultural meanings.

The spatial and temporal distribution of dissolved trace metals has been studied to identify trends in space and time and to evaluate the pollution status in a semi-closed bay (Gohyun bay), Korea. Surface seawater samples were collected over four seasons at 18 stations in the bay between 2003 and 2004 and once at 7 stations around a large shipyard in May 2004. The concentration of Cd, Co, Cu, Ni, Pb, and Zn in seawater in February and May were highly variable in space, showing the higher value relative to other season. Those metals concentrations were decreased from inner-to outer-stations. In around the shipyard, Cu, Pb and Zn showed the higher variability depending on time. Cu and Zn concentrations at the sites around the shipyard had 2 times higher values compared with the average of inner stations in Gohyun bay. The very high correlations between salinity and either Cu and Zn has been showed. Especially, there was a significant relationship between Cu and Zn. We recognize that the shipyard is major source of Cu and Zn in seawater. Therefore, marine environment management policy such as the prevention and control of heavy metal input from a shipyard is required.

Oceanic conditions in walleye pollock habitat in the East Sea have shown decadal fluctuations between warm and cold periods in turn. Specifically, sea surface temperature (SST) has shown a dramatic increase between the late 1980s and the middle 2000s, and abrupt decreasing patterns after the late 2000s. Oceanic conditions in the Dong-han Bay (spawning ground) and middle eastern coastal waters (fishing ground), however, indicated different fluctuation trends in SST, increasing in the Dong-han Bay after the late 1980s, and decreasing after the late 2000s. These fluctuation patterns were especially clear in February and March. Sea surface temperature in the middle eastern coastal waters of Korea soared continuously after the late 1980s, but did not show a distinct decreasing pattern after the late 2000s compared with Dong han Bay, except for February SST values. These long term water temperature changes in both walleye pollock spawning and fishing ground are related to variation in walleye pollock landings. Especially, abrupt changes in spawning ground SST can be one of the factors influencing survival in the early ontogenesis of walleye pollock, including egg and yolk larval stages. During the 1980s, the area of suitable spawning temperature (2-5℃) was wider, and the length of Walleye pollock egg and larval stages greater compared with past and present oceanographic environments. However, such patterns did not correspond with the optimal spawning temperature range and greater length of development of walleye pollock during the late 1980s likely triggering a decline in pollock stock. In conclusion, it has been supposed that the dramatic decrease in walleye pollock landings in the East Sea since the late 1980s was caused by increasing water temperature leading to both early mortality and unsuitable spawning conditions.

Application areas of Knowledge Discovery in Database (KDD) have been expanded into many R&D management processes including technology trends analysis, forecasting and evaluation etc. Established research field such as informetrics (or scientometrics) has recently fully utilized techniques or methods of KDD. Various systems have been developed to support works of analyzing large-scale R&D related databases such as patent DB or bibliographic DB by a few researchers or institutions. But extant systems have some problems for korean users to use. Their prices is not cheap, korean language process not available, and user's demands not reflected. To solve these problems, Korea Institute of Science and Technology Information (KISTI) developed stand-alone type information analysis system named as KnowledgeMatrix. KnowledgeMatrix system offer various functions to analyze retrieved data set from databases. Knowledge Matrix main operation unit is composed of user-defined lists and matrix generation, cluster analysis, visualization, data pre-processing. KnowledgeMatrix show better performances and offer more various functions than extant systems.

Purpose: This study was conducted to analyze food consumption behavior of women by marital status based on the 2015 consumer survey data on Food Consumption Behaviors of the Korea Rural Economic Institute. Methods: We analyzed data describing 3,312 women aged 19 ~ 75 who were the main buyers of foods in their household. The food purchase patterns, dining-out behavior, and use of food-delivery and take-out were investigated. Results: Overall, 40.5% of unmarried women shopped for food once per week and 37.4% spent 200,000 ~ 400,000 won per month. Additionally, 43.1% of married women shopped 2 ~ 3 times per week and 26.6% spent 400,000 ~ 600,000 won (p < 0.0001). Dining-out frequency and one-time cost per person of dining-out for unmarried women were higher than those for married women. With delivery/take-out food frequency, 2 time per week was the highest rate among married women (34.6%) and once per week was the highest among unmarried women (31.2%) respectively. Conclusion: The results of this study indicate food consumption behaviors and trends of Korean women by marital status. This study provides basic data that will be useful for food industries establishing marketing strategies to better meet consumer demands.
