In order to deal with high uncertainty and variability in emergency medical centers, many researchers have developed various models for their operational planning and scheduling. However, most of the models just provide static plans without any risk measures as their results, and thus the users often lose the opportunity to analyze how much risk the patients have, whether the plan is still implementable or how the plan should be changed when an unexpected event happens. In this study, we construct a simulation model combined with a risk-based planning and scheduling module designed by Simio LLC. In addition to static schedules, it provides possibility of treatment delay for each patient as a risk measure, and updates the schedule to avoid the risk when it is needed. By using the simulation model, the users can experiment various scenarios in operations quickly, and also can make a decision not based on their past experience or intuition but based on scientific estimation of risks even in urgent situations. An example of such an operational decision making process is demonstrated for a real mid-size emergency medical center located in Seoul, Republic of Korea. The model is designed for temporal short-term planning especially, but it can be expanded for long-term planning also with some appropriate adjustments.

The focus of this study is to investigate the effect of earnings management and audit quality on the cost of equity capital and also examines whether audit quality acts as a moderating variable for the effect of earnings management on the cost of equity capital. The population in this study are companies from the consumer goods industry sector listed on the Indonesia Stock Exchange (IDX) during the 2016-2018 period. This sector was chosen because it is a sector that is able to survive in conditions of economic decline, so it becomes a good investment opportunity in the future. The sample selection was carried out using purposive sampling technique. By using the Moderated Regression Analysis (MRA) technique, the results show that earnings management has a positive effect on the cost of equity capital. Conversely, companies with good audit quality will bear lower cost of equity capital. The moderating hypothesis test results show that audit quality moderates the effect of earnings management on the cost of equity capital. This means that, even though the company carries out earnings management, investors have more confidence in the results of audits conducted by qualified auditors so that the cost of equity capital is low.

Purpose - There have been many studies regarding the preceding factors required for success of start-up. The purpose of this study is to verify one of the paths by which the individual characteristics of founders and governmental support lead to enhanced start-up performance, via entrepreneurship and network building. Research design, data, methodology - Data for this study was collected from surveys of 332 founders throughout South Korea, and statistical analyses of this data were performed using SPSS 22.0 and Smart PLS 2.0. To verify our hypothesis, path analysis was performed using a structural equation model. Results -The variables, entrepreneurial self-esteem and experience were found to have positive effects on the entrepreneurship and networks. Secondly, governmental support did not have significant positive effect on entrepreneurship, but it did have positive effect on networking. Thirdly, entrepreneurship and networking were confirmed to have positive effects on both the utilization of opportunities and financial performance, which are variables indicating start-up performance. Conclusion - Although founder's characteristics are important for success of start-up, it is also critically important to actively utilize governmental support. Notably, many founders suffer from inadequate networks. They would be able to enhance their start-up performance by utilizing various governmental support programs to reinforce their network capabilities.

This study analyzed the performance of the national fishing port development project, which lacked ex-post impact evaluation despite a lot of investment in terms of fishery income opportunities. Using micro data from the Census of Agriculture, Forestry, and Fisheries, the sales amount of fishery products and the proportion of fishery-related businesses were used as performance indicators. The fishery households in the fishing port area (treatment group) and those not in the area (control group) were classified through data pre-processing, and factors unrelated to the fishing ports were controlled using the propensity score matching difference-in-difference method. The analysis target is six fishing ports with large investment in from 2010 to 2014. As a result of the analysis, it was confirmed that the sales of fishery products increased significantly in four of the six fishing ports, and the proportion of fishery-related businesses increased in two fishing ports. The analysis method of this study can be fully utilized in the evaluation of the Fishing Community New Deal 300 Project, which is in need of performance analysis.

E-business 경제사회가 성장하고 문화, 창조산업은 물론 컨텐츠와 지식산업의 성장이 가시화되면서 기존 기업경영 환경에서 논의되어오던 비즈니스 유형은 더욱 다양하게 확장되고, 이에 대한 새로운 해석과 논의가 이어지고 있다. 이러한 환경변화는 디자인 분야에서도 디자인경영의 확산과 그 동안 영세하고, 비전문적으로 이루어졌던 디자인비즈니스의 새로운 기회를 제공하고 있다. 지금까지 디자인비즈니스는 디자인산업, 디자인서비스의 개념과 동일시되어 독립적으로 논의되어 오던 개념이 아니었다. 특히 디자인비즈니스는 암묵적인 프로세스 내에서 이루어져 왔고, 이는 다시 개념적 불확실성과 체계적인 시스템 부족으로 이어졌다. 때문에 이러한 문제는 독립적인 사업을 통한 자본적, 사회적 성공과 발전기반을 형성하고자 하는 디자인 전문 회사들이나 디자인경영을 활성화하고자 하는 기업들에게 시대적 변화에 적합한 디자인비즈니스 모델개발이나 발전전략 마련에 한계점으로 작용하고 있다. 이에 본 연구는 디자인비즈니스에 대한 명확한 개념정립을 이루고, 디자인비즈니스의 유형을 그 활동 형태에 따라 맞춤형, 기성형, 제공형, 계약형로 정립하고, 비즈니스 대상을 제품, 보조서비스, 지식, 프로모션으로 확대하여 활동형태와 대상에 따른 디자인비즈니스 유형의 구조 틀을 구축하였다. 이는 디자인 비즈니스 유형에 대한 보다 확장된 개념을 제공함으로써 디자인비즈니스 활동의 확산과 다양한 비즈니스 모델 개발을 도울 것이다.

Purpose - Korea has a better geographical location than other nations in the Northeast Asian region. This means that Korea has an opportunity to become the center of international physical distribution in Northeast Asia. Korea should take advantage of this opportunity by exploring appropriate strategies to achieve this goal, assuming government willingness, with a view to capitalizing on the geographical advantage of the Korean peninsula and constructing a comprehensive physical distribution network system. If we prepare for this scenario, Korea could become the center of international physical distribution in Northeast Asia. Research design, data, and methodology - This study has the purpose of determining how shipping companies form partnerships with third-party logistics providers, and the relevant implications. The survey methods used were personal interview and a questionnaire distributed through e-mail, fax, mail, and telephone. A total of 600 questionnaires were distributed, out of which 285 were returned. Of the collected questionnaires, 10 were excluded because of insufficient content, leaving 275 to be used in the study as available valid samples. The data that was collected from these samples was analyzed using the data coating process and by employing a statistical package program. Results - Flexible policies, administration, and systems will be needed to create better business practices. In this dissertation, first and foremost, the results reveal that in order to become the center of Northeast Asian logistics, Korea must transition into a new paradigm based on the current economic and social systems that have stemmed from bureaucracy, inflexibility, chauvinism, and egalitarianism. Flexible policies, administration, and systems will be required to create better business practices. Domestic logistics corporations need to occupy a strategic logistics hub, create a logistics network, and activate value-added logistics business strategies by ensuring significant manpower and by building a logistics information system to strengthen their competitive edge, creating an improved system. Conclusions - In this dissertation, first and foremost, we point out that in order to become a center of North East Logistics, Korea should change to a new paradigm from the old one based on current economic and social systems that have stemmed from bureaucracy, inflexibility, chauvinism, and egalitarianism. More reasonable business laws, systems, and policies based on market-driven flexibility and transparency should be created. Moreover, social norms and rules should be reasonably established, to accomplish political and social security. Korea has to cultivate a culture of tolerance for foreign companies. This involves a change of paradigm for the development of the capital city and satellite cities. It will take a powerful task force or organization to plan and execute the vision that aims to meet these needs, accomplish the necessary goals, use the appropriate system effectively, and make Korea a key country in the field of Northeast Asian logistics.

Data modeling can be regarded as a series of processes to abstract real-world business concerns. The conceptual modeling phase is often regarded as the most difficult stage in the entire modeling process, because quite different conceptual models may be produced even for similar business domains based on users' varying requirements and the data modelers' diverse perceptions of the requirements. This implies that an object considered as an entity in one domain may be considered as an attribute in another, and vice versa. However, many traditional knowledge-based automated database design systems unfortunately fail to construct appropriate Entity-Relationship Diagrams(ERDs) for a given set of requirements due to the rigid assumption that an object should be classified as an entity if it has been classified as an entity in previous applications. In this paper, we propose an alternative automation system which can generate ERDs from business descriptions using association rule mining technique. Our system can be differentiated from the traditional ones in that our system can perform data modeling only based on business description written by domain workers, rather than relying on any kind of knowledge base. Since the proposed system can produce various versions of ERDs from the same business descriptions simultaneously, users can have the opportunity to choose one of the ERDs as being the most appropriate, based on their business environment and requirements. We performed a case study for personnel management in a university to evaluate the practicability of the proposed system This paper summarizes the result of it in the experiment section.
