The main purpose of the study is to analyze the key aspects of state regulation of the hotel and restaurant complex in the system of tourism development and the national economy. The effectiveness of the regulation of the hotel and restaurant complex in the system of development of tourism and the national economy largely depends on the presence of an effective central executive body that would take care of the problems of the development of the industry, the quality and perfection of legal support, a strategic view of programming the development of the industry within the state and regions, as well as administrative mechanisms of public administration, which fully ensure control over the activities of economic entities and the quality of the services they provide. Based on the results of the study, key aspects of state regulation of the hotel and restaurant complex in the system of tourism development and the national economy were identified.

과거에는 경영의사결정에 적절한 정보를 적시에 제공할 수 없기 때문에 불확실한 경영을 했으며 경영자는 주관적인 경험과 판단 등에 의지하였다. 정보기술의 발달과 더불어 발전한 정보시스템과 기술은 비즈니스 운영면에서 고도의 효율성과 생산성을 달성하기 위하여 관리자가 활용할 수 있는 가장 중요한 도구 중에 속한다. 이것의 효과는 비즈니스 실무와 관리행태의 변화가 동반되었을때 더욱 크게 나타난다. 본 연구에서는 기업의 전략적 의사결정에 필요한 문제를 해결하기 위하여 정보기술을 활용하여 필요한 정보를 획득하고 문제해결 방법론을 시뮬레이션 하여 객관적이고 정형화된 경영의사결정을 지원하는 시스템을 개발하기위한 기능요소 및 솔루션을 구조화하였다. 본 연구에서 제안하는 전략의사결정지원 시스템은 기업경영 지원기술에 관련된 것으로 IT기술을 활용하여 경영의사결정에서 요구되는 전략의사결정 문제에 있어서 최적의 시나리오를 선택하도록 하여 신뢰성 있는 기업경영에 도움을 줄 수 있는 시스템이다. 전략의사결정시스템은 개별사업 시뮬레이션과 전사사업 시뮬레이션, 전사사업 포트폴리오 관리 등 크게 세 가지 기능부문으로 나누어 볼 수 있다. 본 시스템은 객관적이고 정형화된 컨설팅 결과를 제공함으로써 신뢰성을 보장할 수 있고, 급변하는 경영 여건에 효율적으로 대응할 수 있는 유용한 효과를 기대할 수 있다.

Mining, construction, and other special vehicles for heavy use are designed to work under high-performance and off-road working conditions. The driving and executive mechanisms of the support structures and superstructures of these vehicles frequently operate under high loads. Such high loads place the equipment under constant risk of an accident and can jeopardize the dynamic stability of the machinery. An experimental investigation was conducted on a refuse collection vehicle. The aim of this research was to determine the working conditions of a real vehicle: the kinematics of the waste container, that is, a hydraulic rotate drum for waste collection; the dynamics of the load manipulator (superstructure); the vibrations of the vehicle mass; and the strain (stress) of the elements responsible for the supporting structure. For an examination of the force (weight) on the rear axle of a heavy vehicle, caused by its own weight and additional load, a universal measurement system is proposed. As a result of this investigation, we propose an alternative system for continuous vehicle weighing during waste collection while in motion, that is, an on-board weighing system, and provide suggestions for measuring equipment designs.

Recently, Open Course Ware service area which offers free lecture materials has been steadily growing. This change comes from a paradigm shift of education service caused by the progress of ICT and a role change of consumers. Knowledge creation from higher educational institutions is slow compared to change of society. Therefore, consumers escape from one-sided education, and perform a new role of knowledge generation. Nevertheless, there is not much of academic research of Open Course Ware. Consequently, the paper is dedicated to empirical study on effect of perceived value, information system quality and brand trust on intention to continuous use. As implications for the research, as a practical point of view, the results-an economic side that offers contents for free of charge, a contents side that is fresh, various and substantial, a systematic side that makes customers to use the system easily, a service side which takes charge of customers support and brand trust affect satisfaction and intention to continuous use - can be used for establishment of executive strategies.

시장 환경 변화가 심한 상황에서 정보화로 기대되는 효과가 기업의 성과에 직결되지 않는 한 적극적인 IT 투자는 기대하기 어렵다. 경영자의 IT투자 의사결정을 유도하기 위해서는 IT투자의 사전평가를 통해 그 투자의 타당성을 입증하는 것이 중요하다. 본 논문은 IT 투자와 그 투자에서 얻어지는 효과를 사전에 분석하여 투자타당성을 평가할 수 있는 방법론을 제시한다. 이 방법론은 IT 소유비용을 체계적으로 분석해서 가시적 인 비용뿐만 아니라 숨겨진 비용도 파악한다. 또한 IT투자로 인한 재무적인 효과와 비재무적인 효과를 화폐가치화 하여 IT ROI를 산출한다. 본 논문은 IT 투자의 객관적인 투자 타당성을 평가하여 IT 투자 의사결정을 지원하고 효율적 인 IT 투자가 이루어질 수 있는 체 계를 제시한다.

Although the corporate governance plays a crucial role in protecting shareholder wealth, the effect of corporate governance on cost of debt is unclear. On one hand, the corporate governance reduces asymmetric information between corporate and external investor including debtholder leading to a decreasing in cost of debt financing. On the other hand, bondholders require higher rate of return for an improvement corporate governance. Hence, this study aims to investigate the relationship between the mechanism to improve corporate governance namely board effectiveness and the cost of debt in an emerging market. As we aim to explore the relationship between cost of debt and board effectiveness, we select corporation in Thailand as our sample because the businesses in Thailand are major debt-financing. Hence, our sample include listed firm in Stock Exchange of Thailand between 2007 and 2016. Our main findings support the sub-optimal investment hypothesis in that improved board effectiveness is associated with higher cost of borrowing. In addition, we find that the number of board member-board size, the number of board meeting, and the percentage of non-executive on audit committee play are positively associated with the cost of debt financing. Furthermore, we perform two-stage-least square (2SLS) to ensure that our results are far from endogeneity issue.

In accomplishing the objectives of the hospital organizations effectively the good results of hospital information systems depends upon the usefulness and forms of informations provided by them under certain conditions. This study is aimed at examining how much hospital information systems are influenced by the characteristics of organizations and information systems. The results are as follows. 1. In the viewpoint of variations of organization characteristics, the support of chief executive group, the participation of users, education and training has good effects on satisfaction rates of users and system utilization rates as evaluation instruments of results of hospital information systems. 2. In the viewpoint of information system characteristics, the nearness of information sources, the scopes and qualities of informations has good effects on satisfaction rates of users and system utilization rates as evaluation instruments of results of hospital information systems. Accordingly interests and supports of chief hospital executives are required in order to heighten the results of hospital information systems, and there must be participations of organization members in their construction and performance. Also there must be training and education of members in the hospital affairs in using them. In such a condition of hospital organizations the good results of hospital information systems will be produced. The above concluded things must be taken into consideration importantly in their introduction and development.

The objective of this study is twofold: first, to investigate how organizations encourage factors that have an impact on employees' entrepreneurial behavior from employee's perspectives and experiences; and second, to discover how and why employees behave entrepreneurially within the organization. A case study method is considered as an appropriate approach to scrutinize intrapreneurial behavior because it principally concentrates on an investigation into a contemporary organizational phenomenon and context concerning entrepreneurial activities in-depth within its real situation. In data collection, an Asian multinational retail company was selected. Semi-structured interviews were carried out with 24 executive-level employees who had been working in various departments for more than 5 years. Each in-depth interview lasts for a duration of 40 to 60 minutes. The results reveal several understandings into the combination of individual-level and organizational-level factors that promote the intrapreneurial behavior and activities of the established firm in the context of Thailand. In this regard, six factors have been found as the key determinants that make an impact on innovativeness, proactiveness, and risk-taking behaviour of the employees. Those factors are personal preference, organizational stability, management support, compensation, reward system, teamwork, quality of relationship with colleagues, work autonomy and the quality of relationship with the superiors.
