This research objective is to determine the optimal price break points for n­block tariff, because comparing non­linear pricing with uniform pricing on the basis of profit, n­block tariff outperforms two­part tariff, all unit discount price schedule, and uniform pricing. Although the merits of non­linear pricing are well documented, the attempt to practice the non-linear pricing in medical service sector has been relatively rare. The determination of the parameters under n­block tariff is the interesting decision making agenda for marketers. Under n­block tariff, the marketers should decide the optimal price break points and the optimal marginal price for each price zone. The results can be summarized as follows: The researchers found that mixture model can be the feasible methodology for determining the optimal number of n­block tariff and identifying the optimal segmentation criteria. We demonstrate the feasibility and the superiority of the mixture model by applying it to the database of medical examination. The results appear that the number of patients per month can be the optimal segmentation variable. And 6­block tariff is the optimal price break for this medical service.

Concerns have been growing about whether domestic internet protocol television (IPTV) can establish a solid foothold in the pay TV market, largely because of the lack of IPTV-only content and service differentiation. It has been difficult for IPTV providers to attract valuable PPs (program providers) to strengthen their positions, and IPTV providers have invested much money into procuring content. To survive this difficult situation, IPTV providers need to reappraise their profit sharing methods and content distribution structure to facilitate the expansion of their subscriber base. This can be done by attracting valuable PPs to IPTV providers and securing extra revenue by distributing more content for their PP partners. The IPTV industry has a different structure and value chain from the digital cable industry. Moreover, profit sharing schemes among participants in the IPTV industry are complicated. Thus it is essential to analyze the criteria for profit sharing, the selection of attributes in profit sharing, and their cause-effect relationship in developing fair pricing for broadcast content in the IPTV industry. This study introduces the attributes that need to be considered for the pricing of content and profit sharing among IPTV providers and PPs. In addition, this study uses system dynamics to analyze the relationship among those attributes along with additional associated factors for the pricing of content.

The purpose of this study was to compare shopping orientations and purchase criteria according to the occupational status; professionals, non-professionals, and homemakers among female consumers. Subjects were selected from mailing lists through a random sampling technique in the United States. Collection of the research data was made using an adaptation of the Total Design Method for implementing mail surveys. ANOVA, Regression, and Duncan Test were used to conduct the data analysis on 254 out of 1000 questionnaires. The three job status showed significant differences in 5 shopping orientations(sex role oriented, fashion conscious, credit oriented, catalog oriented, and value oriented). Even after controlling the effect of income and education level, significant differences were noticed in 4 shopping orientations, the exception being value conscious. Brand, price, and country of origin among the job status groups also showed significant differences in results for purchase criteria.

그 동안 소프트웨어 가격의 적합성에 대한 논의가 끊임없이 이어져왔다. 패키지 소프트웨어를 구매하는 소비자와 공급자 사이의 원만한 거래를 위해서는 시장에서 서로가 수긍할 수 있는 가격 결정 논리가 필요하다. 그러나 현실은 아직까지도 가격을 결정하는 요인들에 대한 정확한 기준이 없을 뿐만 아니라 산정방식에 대한 이해도 또한 부족하다. 이로 인해 공급회사들은 각기 다른 기준에 의해 소프트웨어 가격 산정을 하고 있으며, 소비자는 끊임없이 합당한 가격인가에 대한 의문을 던지고 있는 실정이다. 본 논문에서는 합당한 소프트웨어 가격을 산정하기 위한 다양한 요인들을 분석하고 이를 기반으로 한 패키지 소프트웨어 제품의 적정가격산정 모델을 제시하는 것을 목적으로 한다.

Laboratory inspection and diagnosis is a means of investigating and assessing various hazards or the state of research equipment in a laboratory, then taking appropriate safety measures to prevent accidents and injury. In many cases, laboratory inspection and diagnosis carried out by agencies are performed in a perfunctory manner that only barely satisfies the legal requirements. The aim of the present study is to provide clearly established pricing criteria for laboratory inspection and diagnosis, so as to prevent recurrence of laboratory accidents and to establish a safe laboratory environment. In order to clarify previously unclear matters, such as the lower limit for bids submitted by laboratory inspection and diagnosis agencies, technical manpower requirements, and number of laboratories inspected and diagnosed per day, a questionnaire survey was administered to agency personnel. First, when asked what the lower limit for bids submitted by agencies should be in order to improve reliability of inspection and diagnosis results and make up for the shortcomings of the lowest-bidder-wins system, 85.5% of respondents answered that the lower limit for bids should stand at no lower than 90% of the estimated price. The level of technical expertise among the technical personnel committed to laboratory inspection and diagnosis was shown to impact the reliability of results, and questionnaire results indicated a need to vary technical expertise levels depending on the degree of hazard, substances handled, and equipment used in a given laboratory. Level of technical expertise(67.1%) and number of personnel(52.6%) were shown to have a greater impact on reliability of diagnosis than on reliability of inspection. According to the results, it is determined that three persons(specialist, advanced and intermediate) should be committed to inspections, while four persons(professional, specialist, advanced and intermediate) should be committed to diagnoses. The respondents indicated a larger number of laboratories could be inspected than diagnosed per day. This can be attributed to differences in the amount of work each task involves, and the time each task takes. Assuming a six-hour work day not counting transportation, paperwork and rest, it is thought that inspection of up to 36 laboratories will be possible if each laboratory is assigned no more than 10 minutes(34.7%), while up to 24 laboratories could be inspected and diagnosed if each laboratory is assigned 15 to 20 minutes(35.1%).

The considerations of the electrical device' characteristics and the customers' satisfaction have been important criteria for efficient smart grid systems. In general, an electrical device is classified into a non-interruptible device or an interruptible device. The consideration of the type is an essential information for the efficient smart grid scheduling. In addition, customers' scheduling preferences or satisfactions have to be considered simultaneously. However, the existing research studies failed to consider both criteria. This paper proposes a new and efficient smart grid scheduling framework considering both criteria. The framework consists of two modules - 1) A day-head smart grid scheduling algorithm and 2) Real-time sudden demand negotiation framework. The first method generates the smart grid schedule efficiently using an embedded genetic algorithm with the consideration of the device's characteristics. Then, in case of sudden electrical demands, the second method generates the more efficient real-time smart grid schedules considering both criteria. In order to show the effectiveness of the proposed framework, comparisons with the existing relevant research studies are provided under various electricity demand scenarios.

건설공사 사후평가는 공공건설사업을 대상으로 수요 공사비 공사기간 기대효과 및 사업관리 내용 등을 준공 이후에 재평가하고, 차후 유사사업 추진 시 그 평가결과를 참고하여 발주청의 시행착오를 줄이기 위한 목적으로 2000년부터 도입되었다. 하지만 용역대가 산정기준이 마련되지 않아 사후평가 용역의 질적 저하 및 분쟁발생의 원인이 되고 있다. 본 연구에서는 사후평가 용역데이터를 기반으로 공사비요율방식 및 실비정액가산방식의 용역대가 산정기준을 제시하였다. 용역대가 분석을 위해 기존의 사후평가 용역비와 공사비를 조사하고 공사비요율방식 및 실비정액가산방식을 통해 산출된 용역비를 비교분석하였다. 분석결과 실비정액가산방식을 통해 산출한 용역비가 공사비요율방식에 비해 더 정확함을 확인하였다. 실비 정액가산방식은 시설물별 사업특성을 반영할 수 있도록 거리보정계수, 면적보정계수, 통합보정계수 등 다양한 보정계수가 적용되었으며, 선형공사(도로, 철도), 비선형공사 I(주택 산업단지), 비선형공사 II(공항, 항만, 댐, 상하수도), 기타공사로 시설물 구분을 세분화하여 산정기준을 제시하였다.
