  • This study aims to investigate factors that are important for Korean language faculty and learners in Thai universities with focus on factors that constitute characteristics of desirable Korean language teachers. This study also analyzes the difference in perception between the faculty and learners to enhance the qualities of Korean language teachers in Thailand. The demand for Korean language learners is explosive in Thailand as Korean language has been adopted as a college entrance examination subject since the 2018 school year. As a result, the Thai government has increased the number of Korean language education institutions to reflect the rapidly increasing demand of Korean language learners, but Korean language education in Thailand has only achieved quantitative growth and has made little in the way of qualitative growth. In this respect, it is meaningful to compare the qualities of the Korean language teachers in the Korean language faculty of Thai universities with the qualities that learners perceive Korean language teachers should have, which ultimately can enhance the quality of Thai Korean language teachers and help the learners to learn more effectively.

  • Electric vehicles (EVs) have been growing to reduce energy consumption and greenhouse gas (GHG) emissions in the transportation sector. The increasing number of EVs requires adequate recharging infrastructure, and at the same time, adopts low- or zero-emission electricity production because the GHG emissions are highly dependent on primary sources of electricity production. Although previous research has studied solar photovoltaic (PV) -integrated EV charging stations, it is challenging to optimize spatial areas between where the charging stations are required and where the renewable energy sources (i.e., solar photovoltaic (PV)) are accessible. Therefore, the primary objective of this research is to support decisions of siting EV charging stations using a spatial data clustering method integrated with Geographic Information System (GIS). This research explores spatial relationships of PV power outputs (i.e., supply) and traffic flow (i.e., demand) and tests a community in the state of Indiana, USA for optimal sitting of EV charging stations. Under the assumption that EV charging stations should be placed where the potential electricity production and traffic flow are high to match supply and demand, this research identified three areas for installing EV charging stations powered by rooftop PV in the study area. The proposed strategies will drive the transition of existing energy infrastructure into decentralized power systems. This research will ultimately contribute to enhancing economic efficiency and environmental sustainability by enabling significant reductions in electricity distribution loss and GHG emissions driven by transportation energy.

  • CEPA(Comprehensive Economic Partnership Agreement, hereinafter CEPA) between India and Korea may influence some changes on Korean pharmaceutical industry which shows less competitive advantages than Indian industry in many regards. So the purpose of this paper remains on suggesting the way of enhancing international competitiveness for Korean industry on the basis of double diamond model. Through the comprehensive and deep analysis, our findings on recommendable business strategies for Korea are as follows ; in terms of factor conditions, first, cooperative strategy in R&D for developing generics will be required. Second, Introduction of CMO business can be considered. In terms of demand condition, Korean firms should find out the chance for demand creation in Indian market which has future market potential and American market exploration, as soon as possible. With regards to strategy, structure and competition, trying M&A with leading Indian companies and utilizing well organized medical professionals in India will be considered. In the points of related and supportive parts, lastly, Korean government should try to make so called "National Strategic R&D committee" for pharmaceuticals and bring u-healthcare service to Korea in the first place. If Korean pharmaceutical industry implement above-mentioned strategies, CEPA can be turned into business opportunities from the crisis. As a result, Korean firms shall have more powerful global competitiveness eventually.

  • This study was attempted to provide a scientific basis for the problem of location selection by spatial scale for efficient promotion of projects related to green care farm complex. Location potential assessment system in local government scale consists of two major components from demand-side and supply-side consideration. The demand-side aspect considered the characteristics of potential users, while supply-side aspect used total 18 indices over 8 divisions under 3 fields. For the location potential assessment in district scale, total 8 indices under 3 major divisions were considered based on biological, physical, social, and economic environment. The application results of the location potential evaluation system in local government scale(excluding metropolitan cities) showed high location potential in southern Gyeonggi Province and near Busan Metropolitan City. As a result of applying the district-scale location potential evaluation system to Geumsan-gun, Geumsan-eup, Chubu-myeon, and Jewon-myeon have high potential. Further studies to improve the applicability of the developed indices are recommended by enhancing assessment indices, complementing base data, and reinforcing with spatial analysis.

  • An independent bank guarantee(aka an independent guarantee) is provided as an security on a principal obligor's performance of his obligation, and a guarantor should pay the guaranteed amount only upon a beneficiary's written demand. A standby letter of credit has been used in the United States, since it was construed that a bank should not issue a guarantee. There was wide misunderstanding that a standby letter of credit differs from an independent bank guarantee. However, a standby letter of credit is the same security as an independent bank guarantee, and in international business a standby letter of credit is not differentiated from a independent bank guarantee. An independent bank guarantee are independent from the underlying contract, unconditional, and irrevocable. And a guarantor should pay upon written demand without proving a principal obligor breaches the underlying contract. These features of an independent bank guarantee has been abused in international transactions. Thus it has been proposed that some exceptions to the features of an independent bank guarantee should be allowed. United Nations Convention on Independent Guarantees and Standby Letter of Credit(1995) stipulates some exceptions to payment obligation. Export bond insurance, a part of export insurances, operated by the Korea Export Insurance Corporation under the Export Insurance Act, is used as a security for unfair calling by a beneficiary under an independent bank guarantee. Most of the export subsides by the government are prohibited under WTO's Agreement on Subsidies and Countervailing Measures. However, as export insurance is allowed under the WTO, it operates a significant role in enhancing the export. In the event that export bond insurance is provided for a guarantor, an obligor who is subject to recourse by a guarantor, can be exempt from the recourse in case of unfair calling. The Korea Export Insurance Corporation, an insurer, bears unfair calling risk by a beneficiary. Generally it is understood that a demand shall be made before the expiry of an independent bank guarantee. However this is not absolutely true, it shall be decided by URDG, ISP98, the governing law.

  • The tied braced frame (TBF) system was developed to achieve uniform seismic inelastic demand along the height of multi-storey eccentrically braced steel frames. A modular tied braced frame (M-TBF) configuration has been recently proposed to reach the same objective while reducing the large axial force demand imposed on the vertical tie members connecting the link beams together in TBFs. M-TBFs may however experience variations in storey drifts at levels where the ties have been removed to form the modules. In this paper, the possibility of reducing the discontinuity in displacement response of a 16-storey M-TBF structure by introducing energy dissipating (ED) devices between the modules is examined. Two M-TBF configurations are investigated: an M-TBF with two 8-storey modules and an M-TBF with four 4-storey modules. Three types of ED devices are studied: friction dampers (FD), buckling restrained bracing (BRB) members and self-centering energy dissipative (SCED) members. The ED devices were sized such that no additional force demand was imposed on the discontinuous tie members. Nonlinear response history analysis showed that all three ED systems can be used to reduce discontinuities in storey drifts of M-TBFs. The BRB members experienced the smallest peak deformations whereas minimum residual deformations were obtained with the SCED devices.

  • Objectives: The purpose of this study was to investigate patients' demand for music and art therapy in the treatment of Parkinson's disease and to understand how patients view the use of music and art therapy as a complementary form of treatment that can improve their quality of life and increase their self-efficacy in addition to medication. Methods: To this end, 60 Parkinson's patients visiting Daejeon Korean Medicine Hospital at Daejeon University were surveyed about music and art therapy. Results: The survey demonstrated a highly positive response to the music program, with strong belief in its efficacy for Parkinson's disease and significant interest in participation. Group music therapy was perceived as effective for enhancing mental health, respiratory function, language disorders, and overall quality of life. Although the art program was also deemed effective, patients showed slightly lower interest and willingness to participate compared to music therapy. The patients preferred 60-minute sessions once a week for about 8 weeks. Conclusions: We propose the following directions for a Parkinson's music and art therapy program. First, develop a once-a-week, 8-week music and art program for Parkinson's patients. Second, design the music program to focus on improving respiratory function and quality of life. Third, the art program focuses on creating a sense of security and comfort through emotional exchange among patients and improving self-efficacy.

  • 오늘날 대부분의 기업들은 외부상황에 신속하게 비즈니스를 바꿀 수 있도록 하는 온디맨드 비즈니스 (On-demand business)를 구현하기 위해 IT 시스템의 유연성을 필요로 한다. 서비스 지향 아키텍처(Service Oriented Architecture: SOA)는 온디맨드 운영환경에서의 비즈니스 유연성을 가능하게 하는 인프라스트럭처 (infrastructure)를 제공한다. 오늘날의 이러한 요구사항을 충족시키기 위하여 SOA 애플리케이션 개발에 맞게 비즈니스 프로세스의 유연성을 확보하고 재사용을 증진시키기 위한 접근법이 필요하다. 그러므로 본 논문에서는 소프트웨어 프로덕트 라인 방법의 가변성 분석 기법을 사용하여 비즈니스 프로세스 패밀리 (family)에서 나타날 수 있는 가변성을 분석하고 이를 명시적으로 비즈니스 프로세스 패밀리 모델 (Business Process Family Model: BPFM)로 표현하는 방법을 제시한다. 또한 이 방법의 사용을 지원하기 위해 개발한 도구에 대해 설명한다. 이는 BPFM을 모델링하고 BPFM으로부터 가변성 결정과 가지치기 과정을 거쳐 자동 비즈니스 프로세스 모델 (Business Process Model: BPM)을 생성하는 기능들을 가지고 있다. 본 논문에서 제시하는 비즈니스 프로세스 패밀리의 가변성 분석을 통하여 비즈니스와 이를 지원하는 IT 시스템은 비즈니스 환경의 변화에 신속하게 대응할 수 있게 된다.
