  • Most commercial vehicles have adopted the hydraulic power steering system. To reduce fuel consumption and to improve steering controllability, a hybrid electric power steering system is being developed for commercial vehicles. In this study, the HILS (Hardware In the Loop Simulation) system equipped with a commercial vehicle hybrid electric power steering system was developed and the vehicle dynamic performance of a truck with the steering system was evaluated. The hybrid electric power steering system is composed of the EHPS motor pump, column mounted EPS system, and ball nut steering gear box for heavy commercial vehicles. The accuracy of vehicle models equipped with the HILS system was verified with comparisons between the simulation results and field test results. The road reaction forces of the steering system were generated from the vehicle model and verified using field test results. Step steering tests using the verified HILS system were carried out and the performance of a newly developed commercial vehicle hybrid electric power steering system was evaluated.

  • Each of China, Taiwan, Japan and Korea is in international trade one of the major countries in Asia and has been influenced by the Chinese character culture and the Civil law system. All these countries have their own commercial dispute resolution system for international trade dispute and commercial arbitration mechanism in their countries. They are making their own effort to internationalize and improve their commercial arbitration system. Among these countries China enacted a new arbitration law already. At that time Chinese arbitration law was referred to the UNCITRAL Model Law on International Commercial Arbitration for internationalization of Chinese commercial arbitration system. China also internationalized the panel of arbitrators by increasing the foreign arbitrators of the panel of arbitrators of CIETAC. These measures adopted by China will be the model of dispute resolution and the commercial arbitration system in other major countries in Asia.

  • As the volume of trade between Korea and Vietnam increases, the number and amount of commercial disputes between Korean and Vietnamese companies are increasing. In the case of Vietnam, due to differences in the arbitration system and norms due to the socialist state system, foreign companies lack confidence in the settlement of disputes through commercial arbitration in Vietnam. At this point, it is necessary to not only discuss commercial disputes and settlements, but also to closely review and understand Vietnam's commercial dispute settlement system. Therefore, this study examines the current status and characteristics of Vietnam's commercial disputes and analyzes the actual problems of Vietnam Commercial Arbitration System that arise through the arbitral award of the Vietnam International Arbitration Center (VIAC), Vietnam's representative arbitration agency, and precedents on the recognition and enforcement of foreign arbitration awards in Vietnamese courts. In the end, this study seeks to revitalize the Vietnam Commercial Arbitration so that each disputed party may quickly deal with the commercial disputes, and seeks a more smooth solution through commercial arbitration in future trade claims between Korean and Vietnamese companies.

  • It is difficult to access and share design data among heterogeneous CAD systems. Usually, different CAD systems exchange the design data using a neutral format such as IGES or STEP. A prototype CAD system which uses a geometric kernel and a commercial database management system has been implemented. The prototype system used the Open Cascade geometric kernel and the commercial object-oriented database ObjectStore. STEP provides the database schema. The database can be accessed from commercial CAD systems such as SolidWorks or Unigraphics. The data access module from a commercial CAD system is developed with the CAD system's native API, ObjectStore API functions, and ActiveX.

  • The purpose of this study is to provide a logical basis for guarantee the effectiveness of the tax support system, which is one of the main measures to prevent the side effects of commercial gentrification. For this purpose, this study analyzes the combination of tax support to replace the loss of net rental income due to stabilize commercial rents and annual rent increase rate that can be substituted through the tax support system based on economic utility of commercial lessors in Seoung-dong, Seoul. The result of this study shows that the tax support system can be used as an effective means to substitute a considerable portion of the net rental income loss due to stabilize commercial rents of Seongsu-dong. However if the rent price continues to rise every year, the tax support system does not work. In order to guarantee the sustainability of the tax support system, annual rent increase rate should be kept below a certain level.

  • 무기체계에 상용부품을 적용하는 개념인 COTS (Commercial-Off-The-Shelf)는 국방기술이 민수기술을 선도하던 시기에 크게 호응을 얻지 못했다. 그러나 IT기술의 급속한 성장과 민수산업의 빠른 확장은 짧은 시간에 저가의 대량생산 체계를 갖추게 되었고, 비용과 일정의 장점이 부각되면서 민수분야에 생산되는 부품들이 무기체계에 적용되었다. 민수기술이 국방 무기체계에 사용되기 위해서는 전투 환경의 극한 제약사항에서 성능을 보장할 수 있어야 한다. 일반적으로 상용부품은 설계 및 생산에 대한 요구조건이 군용과 비교하여 다르기 때문에 근본적인 한계가 있다. 따라서, 상용부품이 무기체계에 사용되기 위해서는 시스템공학적 접근을 통한 확인이 요구된다. 본 연구에서는 무기체계에 COTS를 적용하기 위한 방안으로 해양 무기체계 특성에 적합한 프로세스와 제약사항 분석방안을 제시하였다. 해양 무기체계의 제약사항을 일반 환경 및 특수 환경 제약사항으로 구분하고 세부적인 프로세스를 제시하였으며, 시장에서 이러한 제약사항에 적합한 제품을 선택할 때 유용한 도구를 제시하였다. 마지막으로 COTS의 해양 무기체계 적용을 위한 사례연구로 전투함 전기시스템의 COTS 적용 및 제약사항 분석 결과를 확인하였다.

  • The study uses the audited financial statements of 26 Vietnamese commercial banks listed on the Ho Chi Minh City Stock Exchange (HOSE) and Hanoi Stock Exchange (HOSE) during the 2008-2018 period to estimate the system GMM model, which provides empirical evidence on the effect of the variables of customer deposit to total assets (DEPO) ratio, loan to assets (LTA) ratio, liquidity of commercial banks (LIQ), credit development (CRD) ratio, external funding (EFD) ratio, and credit loss provision (LLP) ratio on liquidity risk. The study confirms that commercial banks' internal factors play the most important role, and there is no empirical evidence on macro variables that affect liquidity risk. Finally, in accordance with the theoretical framework, the study uses an estimation method with the R language and the bootstrap methodology to give empirical proof of the nonlinear correlation and U-shaped graph between commercial bank size and liquidity risk. The importance of commercial bank size in absorbing and moderating the effects of liquidity shocks is demonstrated, however, excessive growth in commercial bank size would increase liquidity risk in commercial bank operations.

  • Purpose - This study aims to determine the problems and limitations of the Commercial Area Activation System, which was created by a special law for promoting traditional markets and shopping districts to revitalize and efficiently manage the central commercial area in different regions. We also suggest different options for its improvement. Research design, data, and methodology - We also look into the problems of which is being promoted as a demonstration project, from the aspects of legal text and guidelines. Results - The current commercial area activation system has several problems. First, the establishment of a comprehensive basic plan on the commercial area activation is not a requirement. Second, the benefit principle should be established to prevent the moral laxity of merchants who serve important roles in the main components of the commercial area activation business when they conduct their business. Third, the current special law constrains the commercial management organization, as under the civil law yields a limitation on finding a profitable business model. Fourth, to efficiently, constructing a system that links the other central government businesses and is needed. into a regional development budget or a budget for funding small businesses that the central government can control, which is effective. Further, we offer some suggestions for medium- and long-term policies. First, an integrated coordination mechanism at the central office level should be installed while setting the basic policy to revitalize the Based on this policy, local governments need a system that exclusively based on the after establishing a comprehensive plan for urban regeneration and getting approval from the integration organization. Second, a system that enables an understanding of the problems with business promotion by monitoring the procedure of supporting projects and regularly assessing business achievements is needed. Third, a plan is needed for resolving conflicts between various interested parties that adopts the commercial area activation system for carrying out a total redevelopment of the commercial area where small shops are densely located. A market maintenance project has been conducted as a means to recover our traditional market, which was economically depressed, and to revive the local economy, but it is mostly conducted in the form of reconstruction or redevelopment and represents the interests of landowners and merchants. Thus, it is most likely to lead to a gradual disappearance of traditional markets. Conclusions - This study looks primarily into the problems that appeared in the legal text or the guidelines regarding the direction of improvement of the commercial area activation business that has been going on as a demonstration project since 2011 and suggests some solutions.

  • This study aims to develop the methodology based on the AHP(Analytic Hierarchy Process) of evaluation for commercial paper. commercial paper is the ma product of merchant banks. commercial paper evaluation is annually performed by the credit-evaluation agency. Credit evaluation is performed by the informal judgemental system, which has potential to induce serious inconsistencies in decision-making. We present an objective scoring model which does not suffer from the weakness of the subjective judgement system. The model used is illustrated by analyzing the commercial paper evaluation for the 3 motor-companies(H, K and S motors).
