In order to derive a plan to increase the field effectiveness of the safety and health management(SHM) system, this study suggested plans for practical application of SHM system to the actual sites managed by the branch office of a public enterprise along with practical implications that should be considered. For this, in-depth interviews were conducted with employees in charge of safety and health work at the sites to analyze SHM system of the branch office, and the implementation processes and frameworks for establishing SHM system were suggested by grasping the actual conditions of the construction company performing the construction ordered by the branch office. This study shows that in order for SHM to be internalized in public enterprises, plans and performance indicators that can be applied in the field should be specifically presented in consideration of the hierarchical structure and processes of the organization performing the work, and a work environment should be created to focus on practical works related to safety and health.

In this study, we want to verify the factors that affect the intention to switch to a supply chain management information system applied with blockchain. To this end, variable selection and research model were constructed through the review of previous studies, and empirical analysis was conducted using the TOE framework and PPM model. The effects of Push and Pull factors on the intention to switch to the block chain system and the moderating effect through the switching cost which is a Mooring factor, were verified. The hypothesis was verified using a structural equation model using a sample of 320 response data by conducting a questionnaire survey on small and medium-sized enterprises located in Korea. As a result of the study, social influence, which is a push factor, and management's will to innovate, which is a Pull factor, had a significant effect on switching intention. And the moderating effect between the groups with high and low switching cost recognition was confirmed. This study is significant in that it presents the concept and research direction of SCBM (supply chain & blockchain management) that can enhance the competitiveness of a company through the implementation of a blockchain-based supply chain management information system.

기업의 목적은 이익을 창출하는 데 있다. 이를 위해서는 제품별 생산성을 높여 원가를 절감해야 하지만, 대부분의 레미콘 제조업체는 원가관리를 운영하지 못하고 있는 실정이다. 레미콘 제조업체의 제품공정은 단순하나 제조원가 중 직접재료비가 약 70% 이상으로 큰 비중을 차지하고 있다. 따라서 원가절감의 여부가 경영성과에 미치는 영향이 크다고 할 수 있다. 또한, 정부 공공기관 등은 예산을 안정적으로 관리하고, 부당한 지출을 방지하기 위하여 엄격하게 원가계산제도를 운영하고 있다. 레미콘 제조업체의 원가관리를 위해서는 우선적으로 업체 특성에 맞는 원가관리 시스템을 구축하여야 한다. 이를 위해서 본 논문에서는 레미콘 제조업체의 특성에 맞는 원가관리 시스템을 설계하였다. 시스템 설계는 전체 프레임워크, 처리 절차, 데이터베이스 스키마와 자료구조, 입력 출력 설계로 구성하였다. 원가계산의 절차는 정부원가계산 제도를 이용하여 설계하였다. 본 논문의 성과로, 계약자는 원가정보를 신뢰하며 이용할 수 있고, 레미콘 제조업체의 원가정보 표준화에 기여할 것으로 기대한다.

오늘날 기업 내 ERP(Enterprise Resource Planing)시스템 도입이 활발해지고 있는 가운데 그 역기능으로 ERP 시스템 도입 실패 사례 또한 증가하고 있다. 이로 인해 ERP 시스템이 올바르게 구축되었는가를 판단하는 ERP 시스템에 대한 완성도 혹은 하자여부를 판단하는 감정평가 활동이 증가하고 있다. ERP 시스템은 일반적으로 패키지 형태의 프로그램과는 달리 비즈니스 프로세스 분석 단계에서 계약의 내용이 수정 및 확정되어지며, 업종 및 국가별 비즈니스 프로세스 특성에 따라 일반화된 모듈 프레임 워크를 그대로 적용하기 어려운 점을 가지고 있다. 따라서 본 연구에서는 ERP 시스템 완성도 감정평가를 위해 국내외 ERP 시스템에 대한 기본구조와 함께 세부적인 (공통/상이)모듈에 대해 정리를 수행하고, 이를 대상으로 핵심적인 비즈니스 업무수행을 위한 세부적인 절차를 추출하고자 한다. 본 연구를 통하여 제시된 ERP 시스템 감정 절차는 ERP 시스템 감정을 위한 기초자료로 활용될 수 있다.

ebXML(Electronic Business using extensible Markup Language) is an XML based new international standard framework of the electronic business. Interoperability among mutually different industry fields can be realized by reusing core component, as a infrastructure of data. For this interoperability, it is needed to define the concrete concept of core component, through analyzing the role and applicability of the core component in business process which defines the interoperability among different companies. Therefore, in this paper, we Inquire the role of the core component in the ebXML, and implement the core component storage system which generates core component to register in registry/repository. The designed system for storing the core component generates suitable core component structure to register in registry/repositor), which can be used to generate new business information entity in a modeling step of business process.

This study analyzes the past and present of service science research as a central discipline that will lead a new economy and society, and presents a guide for future research. In the 21st century, service research has developed into a new discipline that is different from the existing service studies. Service science is a discipline that collectively refers to all research related to services. This study analyzes this development process and suggests the direction of future service science research. First, we analyze the research before the birth of service science, an early model of service studies. And the early research on the birth of service science is analyzed. Through this process, the service science framework that expanded and developed the initial service science is analyzed. We introduce each field of service science, which is a new innovation of the existing academic system from a modern perspective, and analyzes the structure of the service philosophy that is the basis of independent academic fields. And we suggest the future direction of service science research. The direction of paradigm innovation research of existing individual disciplines is presented first. As an example, innovation from existing business administration to service business administration is introduced. We also suggest a new economic and social system research direction that requires the convergence of multiple academic fields. Finally, we present a direction for multidimensional, broad-based convergence research. We suggest that the future of service science can be the process of reverting back to integration and convergence, centered on humans and the world, of the disciplines that have continued to diverge in the history. We present a model in which all disciplines are reintegrated into service science as the Eastern and Western spirits converge.

In ebXML, a representative framework for electronic commerce, a BPS (Business Process Specification) should be finally defined as an instance of XML-version BPSS for the configuration of B2B (Business to Business) runtime systems . In order to define the instance more complete and consistent, it is required to validate all the semantic constraints on the instance . Due to the limitations of XML Schema constructs, however, current XML-version BPSS fails to specify formal semantic constraints completely. This paper presents how to find, express and reuse BPSS semantic constraints that could not be explicitly defined in the XML-version BPSS. The method facilitates the validation of XML-version BPSS instances easily with some useful guides for fixing violations of semantic constraints. Furthermore, B2B business processes can be standardized and applied more efficiently and effectively.
