As electric power systems have been moving from vertically integrated utilities to a deregulated environment, the charging of reactive power management is a new challenging theme for market operators. This paper proposes a new methodology to compute the costs of providing reactive power management service in a competitive electrical power market. The proposed formulation, which is basically different from those shown in the literature, consists of two parts. One is to recover investment capital costs of reactive power supporting equipment based on a reactive power flow tracing algorithm. The other is to recover operational costs based on variable spot prices using the optimal power flow algorithm. The charging shapes resulted from the proposed approach exhibit a quite good meaning viewed from a practical sense. It turns out that reactive power charges are mostly due to recovery of capital costs and slightly due to recovery of operational costs. The method can be useful in providing additional insight into power system operation and can be used to determine tariffs of a reactive power management service.

Korean mobile telecommunications market is shifting from 2G to 3G service. Considering the revenue of voice-based communication has reached its maximum, 3G services can provide telecommunication companies with the opportunity to increase their revenues. As the competition in the market is becoming fierce, mobile carriers are trying to increase their profits by preventing their customers from switching to rivals. In this regard, managing customer can be a key success factor of the mobile telecommunications business by retaining existing customer. In this research, we tried to develop and test a model that aids further understanding of the determinants of continuance intention to use the current 3G service. We conducted empirical study through the analysis of 3G service users' data in Korea. The results indicated that continuance intention to use the current 3G is dependent on the customer's satisfaction with the service quality, handset, and brand image. We hope that analysis results will have significant implications in terms of both practical and theoretical aspects.

Due to economic turbulence and fierce competition in the IT service industry, companies have been seeking breakthrough of offerings by investing in research and development (R&D). This paper aims to examine the impact of R&D expenditure size on financial performance focusing on Korean IT service companies. The expected growth rate of revenue and net profit in the upcoming two years were analyzed based on three groups according to different R&D expenditure rates using collected data from 100 of IT service companies. Unlike our presumptions, our finding presents a non-significant relationship between the R&D expenditure size and companies' financial performance. An interesting result among others is that all companies invested in R&D strongly believe there will be an increase of their financial performance in the future.

기업의 경쟁력은 본질적으로 기업이 생산하는 제품이나 서비스의 가치에 의존한다. 왜냐하면 가치가 높은 제품이나 서비스는 고객으로 하여금 구매행동을 유발하기 때문이다. 서비스 믹스는 제품의 물리적 특성과 서비스의 최적결합을 통해서 고객을 위한 가치창출을 통해 경쟁력을 창출하는 프로세스이다. 본 연구에서는 기업에서 서비스 믹스가 기업경쟁력에 미치는 영향에 관한 연구를 통해서 우리나라 제조 기업의 경쟁력 향상에 기여하고자 한다. 경쟁우위를 위한 접근은 흔히 산업 구조 경쟁이론과 자원기반 관점 접근에 의존하고 있다. 그러나 산업 구조에 경쟁 이론은 어느 산업이 매력적인 산업 인가를 발견 하는 데에도 도움이 되지만 어느 기업은 특정의 산업에 진출하여 성공 할 수 있고 다른 기업은 실패하였는가에 대해서는 별다른 도움을 주지 못한다고 논의되고 있다. 자원기반 관점 절은 경쟁력 제고에 많은 공헌에도 불구하고 기업 전략 분석을 위한 이론이나 체계적인 틀은 제시하지 못하는 한계성이 있다. 본 연구에서는 이러한 한계성을 극복하고, 기업의 경쟁력 향상을 위하여 파워 프로세스 적 접근을 적용하였다. 파워프로세스는 권력요소, 가치, 욕구, 환경, 관계의 다섯 권력결정요소의 상호작용에 의해서 권력원천인 가치를 창출하는 프로세스이다. 즉 파워프로세스는 권력주체의 목적을 달성하기 위해서 권력객체를 만족시키는 가치를 창출하는 프로세스이다. 본 연구는 파워프로세스의 관점에서 서비스믹스 전략을 수립하여 우리나라 제조기업의 경쟁력 향상에 기여고자 한다.

One of the major challenges confronting a multiservice electric utility is the establishment of the right prices, for its services. The key objectives of particular pricing schemes are reasonableness of company earnings. Economic efficiency, the responsiveness of supply and of the allocation of sources to the desires of consumers, and maintenance of some degree of competition. This paper proposes a value-based pricing mechanism amenable to the current deregulation situation in electricity market allowing service differentiation. The proposed pricing mechanism can be implemented ina nodal auction model, and can also be applied to direct load control.

본 연구는 사회학적 신제도주의 관점에서 노인장기요양서비스를 제공하는 조직들이 평가제도를 어떻게 채택하고 집행하는지를 동형화와 분리현상으로 해석하였다. 이를 위해 장기요양서비스를 제공하고 있는 7개 기관을 대상으로 심층인터뷰를 한 자료를 질적 내용분석 하였다. 분석결과, 평가제도가 장기 요양기관의 공식적인 구조에 있어서는 동형화를 이끄는 것으로 나타났다. 그러나 장기요양기관 평가제도가 의도한 공급기관 간 경쟁을 통한 효율성을 촉진하는 방식으로 채택되기보다, 정부자원에 의존하기 위해 강압적으로 평가제도를 채택하는 것으로 나타났다. 이러한 결과는 평가제도가 정부규제에 의해 장기요양서비스를 표준화하는 양상으로 집행되고 있음을 확인시켜주었다. 또한, 동형화에 수반되는 조직의 공식구조와 실제 활동의 분리현상도 부분적으로 관찰되었다. 무엇보다 분리현상은 정부역할로서 조직의 이중구조에서 발생할 수 있는 비효율성의 문제를 개선할 수 있는 평가체계의 운용이 요구되며, 특히 돌봄 서비스의 고유성을 반영한 평가지표에 대한 개선이 시급함을 보여준다.

Although word-of-mouth (WOM) has been regarded as one of the very important topics in consumer research, its effects on other aspects of consumer behavior have been scarcely investigated in the context of health-care service industry. The WOM literature also suggests that it is essential for medical care service organizations in fierce competition to adopt WOM communication as a competitive weapon so as to be able to stay ahead of competition. The goal of this research was set to empirically study various relationships between antecedent variables, WOM acceptance, and purchase of medical care services. Specifically, drawing on the WOM literature, eight antecedents to WOM acceptance were selected first. Based on the relevant literature, seven sets of hypotheses on the relationships among antecedents to WOM, WOM acceptance, purchase intention and purchase of medical services were developed. Data were collected via an on-line survey. A total of 571 out of 600 responses turned out to be usable. The major findings of this study can be summarized as follows: First, 6 out of 8 antecedent variables to WOM acceptance were found to be positively affect WOM acceptance. However, the effects of (1) "newness of technology" pertaining to medical care service characteristics and (2) "involvement in health", one of receiver characteristics, were found to be insignificant. Second, most moderating effects on the relationship between purchase and purchase intention of medical care services were found to be insignificant with one exception. That is, elapse of time was found to be a marginally significant moderator on the relationship between purchase and purchase intention of medical care services. Third, it was found that the higher the WOM acceptance, the higher the purchase intention of medical care services. Finally, the effect of WOM acceptance was found to be particularly strong when WOM contents were perceived as useful and positive. Overall, it seems essential for hospitals to actively adopt WOM communication as a competitive marketing tool if they plan to improve their business performance. In this respect, the current study may serve to improve the business performance of hospitals by way of providing theoretical and empirical evidence on the effects of WOM communication variables on WOM acceptance and medical care service purchase.

Tourism and hospitality have encountered significant changes in recent years as a result of the rapid development of information technology (IT). Customers now expect more expedient services and customized travel experiences, which has intensified competition among service providers. To meet these demands, businesses have adopted sophisticated IT applications such as ChatGPT, which enables real-time interaction with consumers and provides recommendations based on their preferences. This paper focuses on the AI support-prompt middleware system, which functions as a mediator between generative AI and human users, and discusses two operational rules associated with it. The first rule is the Information Processing Rule, which requires the middleware system to determine appropriate responses based on the context of the conversation using techniques for natural language processing. The second rule is the Information Presentation Rule, which requires the middleware system to choose an appropriate language style and conversational attitude based on the gravity of the topic or the conversational context. These rules are essential for guaranteeing that the middleware system can fathom user intent and respond appropriately in various conversational contexts. This study contributes to the planning and analysis of service design by deriving design rules for middleware systems to incorporate artificial intelligence into tourism services. By comprehending the operation of AI support-prompt middleware systems, service providers can design more effective and efficient AI-driven tourism services, thereby improving the customer experience and obtaining a market advantage.
