Designation and Application Status of State-Designated Cultural Property, Scenic Sites
Jaehyun Rho,Heekyung Son,Inae Kang,Taehie Park 전북대학교 휴양및경관계획연구소 2017 휴양및경관연구 (J East Asian Landscape Studies) Vol.11 No.1
While designation status of state-appointed cultural properties, promotion status of scenic sites, overlap with natural parks, and relationship with both nine river bends and eight views were reviewed, application and promotion status of scenic sites were analyzed by exploring culture and tourism websites of local governments and tourist leaflets on scenic sites. The results of the analysis are as follows. There are totally 109 designated scenic sites in Korea and these are distributed in 59 local governments, which account for 26.1% of local governments. Accordingly, unequal regional distribution was found to be significant. As a result of the exploration of the status of overlapping between scenic site-designated areas and national, provincial, and county parks, altogether 53 designated scenic sites that account for 48.6%, overlapped with natural parks. Thus, there is a great need for role sharing and cooperation with natural park management entities in terms of experience programs within scenic sites and cultural commentaries. Meanwhile, there is a significant difference among the local governments regarding the efforts in highlighting cultural properties as tourist resources while universal awareness and promotion of scenic sites was found to be very low. Marking scenic sites on leaflets were prone to lag behind those on homepages. The analysis on status of scenic sites revealed that festivals and events were being held in 39.4% of scenic sites and those with longer designation- lapsed years were associated with the prevalence of festivals. Moreover, natural scenic sites located in natural parks were unwilling to be used through local government’s awareness and tourism endeavors compared to historical and cultural scenic sites. Additionally, several wrong descriptions were found on the markings of scenic sites and thus, promotion of scenic site culture and operational management requires urgent improvement.
Contorted polycyclic aromatic hydrocarbon: promising Li insertion organic anode
Park, Jaehyun,Lee, Cheol Woo,Joo, Se Hun,Park, Ju Hyun,Hwang, Chihyun,Song, Hyun-Kon,Park, Young Seok,Kwak, Sang Kyu,Ahn, Seokhoon,Kang, Seok Ju The Royal Society of Chemistry 2018 Journal of Materials Chemistry A Vol.6 No.26
<P>Enhancing the performance of carbon-based anode materials in Li-ion battery (LIB) systems is of considerable interest in terms of next-generation LIB host electrodes, because the unique reversible intercalation-de-intercalation process of such materials ultimately facilitates increases in LIB performance and longevity. This study explored the potential of a new class of carbon-based contorted hexabenzocoronene (c-HBC) as an anode material for high-performance LIB systems. The exploitation of the polymorphic crystalline nature of c-HBC resulted in successful development of a LIB anode based on a newly found crystal phase of trigonal <I>R</I>3̄ by solvent and subsequent thermal annealing. Our in-depth analysis based on cross-sectional transmission electron microscopy, grazing incidence X-ray diffraction, and computational investigation revealed further advantages of using contorted molecules in LIB systems. For instance, the resulting electrochemical characteristics using half-cell architecture clearly reflected single-stage Li insertion behavior associated with the large interspacing and short diffusion length of c-HBC molecule during the discharging process. In addition, the battery exhibited excellent rate capability and cycle endurance, highlighting the suitability of c-HBC as an anode material for high-performance LIBs.</P>

Purpose: The purpose of this study is to examine the structural relationship among relationship marketing, relationship quality, and behavioral intention toward children sports centers. Research design, data, and methodology: To achieve this purpose, this study employed a convenience sampling method via a questionnaire dissemination. A total of 427 responses were collected from the parents of six children sports centers. Among those, 21 responses were excluded as they were not completed, leaving 406 valid data. For hypotheses test, the collected data was computed in SPSS 27.0 and AMOS 27.0, and analyzed with frequency analysis, correlation analysis, reliability analysis, confirmatory factor analysis, and structural equation modeling analysis. Results: First, relationship marketing had a positive influence on relationship quality. Second, relationship marketing had a positive influence on behavioral intention. Third, relationship quality had a positive influence on behavioral intention. Conclusions: Results showed that relationship marketing had a positive influence on relationship quality and behavioral intention. Moreover, relationship quality had a positive influence on behavioral intention. These findings indicate a positive function of relationship marketing in building psychological and behavioral outcomes in the context of children sport industry. Given this, implications of relationships among research variables were discussed.

Various 3D field physics challenges of magnetically confined plasmas arise when the driving source comes from either externally applied non-axisymmetric 3D magnetic perturbations or plasma instabilities inside the plasma. Recently, several key outstanding topics of 3D field physics have been extensively studied in the Korean Superconducting Tokamak Advanced Research (KSTAR), such as edge-localized-mode (ELM) control by resonant magnetic perturbation (RMP), error field (EF) control, 3D field effects on rotation and transport, and RMP-induced alteration of divertor heat flux and detachment. KSTAR has a few physically unique features (i.e., high rotation and long-pulse plasmas with a low intrinsic EF) and machine/diagnostic capabilities (i.e., 3-row in-vessel control coil and state-of-the-art 2D/3D imaging diagnostics), which have been taken advantage of until now to address critical 3D field physics issues relevant to ITER and K-DEMO. Among many remarkable achievements are the robust access to and control of n = 1 RMP ELM suppression, along with a development of its physics basis tools, parameter expansion, optimization, and long-pulse control techniques. Nonetheless, a series of unresolved 3D physics themes, as well as limited coverage of 3D field operating regimes, have also been identified as future works for the 3D field research in KSTAR. In this paper, we provide an overview about the recent progress of KSTAR 3D field physics and present future plans of KSTAR 3D research toward a future fusion reactor.
