To identify the changes in professional care patterns after the introduction of medical insurance in Korea, professional care in hospitals and clinics of two succeeding years were compared. The hospitals and clinics selected for this study were those which located in Seoul city. Hospitals were classified into 3 categories: university hospital, general hospital and hospital. The diseases selected for this study were acute appendicitis and normal delivery. They were selected because their disease courses are considered to be fairly stable. The variables used for this study were length of stay, total hospital costs, costs of each components of cares. The information used for this study was obtained from the official forms requested by the medical facilities to the Korea Medical Insurance Corporation. The two periods studied were 3 months of each year from March 1st to May 31st in 1979 and 1980, The total number of normal delivery studied was 289 in 1979, 301 in 1980 respectively and the acute appendicitis was 92 and 111 respectively. In order to compare the quantity of medical care between 2 study periods the insurance price scores of 1979 were converted to prices of 1980. For statistical test of difference between 2 periods T-test and Welch's test were used. The result of the study were briefly summarized in below. 1. No significant difference was observed in the average length of stay of both disease between two study periods in all types of hospitals. 2. No significant difference was observed in the average total hospital costs of both diseases in all types of hospital, but in the private clinic the average clinic costs was rather decreased significantly in 1980. 3. More cost decrease were seen than cost increase in 1980 in all types of facilities, More cost changes by items were seen in acute appendicitis than in normal delivery between two study periods. The total hospital costs can be devided into 2 portions: charges for drug and material and for physician. In normal delivery, costs for physician's charges was significantly decreased in almost all the hospitals and costs for drug and material were not changed significantly in all the hospitals in 1980. In the university hospitals, however, the costs for drug and material were increased significantly in 1980. The cost decrease for physician's charge were mainly due to the decrease in the costs of laboratory test, treatment and physical therapy. The increase in the costs for the drug and material in the university hospitals was mainly due to the increase in the cost for drugs for oral administration and injection. 4. The proportion of components of medical care in the hospital has not been changed significantly, however, the cost for injection in normal delivery was characteristically increased in 1980 in all hospitals studied. In general the proportion of the costs for drug and material was tended to increase and the costs for physician was tended to decrease in 1980. The increase in the costs for drug and material were considered to be due to increase in the cost for drugs for oral administration and injection. The decrease in the costs for physician were due to decrease in the costs of laboratory test, treatment and physical therapy. Above mentioned changes in hospital and clinic care patterns are considered to be mostly influenced by the review criteria set by the K.I.C. for the assessment of the fee request made by clinics and hospitals.

This study attempts to explain the mechanism behind the migration from vertically integrated value chain architecture to an innovation ecosystem consisting of horizontally separated layers in value chain. We first present a comprehensive framework based on the theoretical analysis of the drivers for migration to an innovation ecosystem, which are standard (institution), capability distribution, and transaction costs. The theoretical framework suggests that the migration to an innovation ecosystem is explained by the influence of standard on the evolutionary change of capability distribution and transaction costs. In particular, when the new de-jure standard competes with the de-facto standard, the new de-jure standard has the greatest impact on the distribution capabilities and the transaction costs. Based on this theoretical framework, we analyze the latest SDN (Software Defined Networking) case of the network industry. SDN standard has transformed the industry from a vertically integrated value chain architecture to a horizontally separated one with its influence on the distribution capabilities and the transaction costs in the industry.

This study estimates a structural model to examine the causal relationships among web browsing, switching cost, and site retention in the context of apparel shopping website. A total of 499 usable questionnaires were obtained from consumers aged from 20 to 49 years. For data analysis, exploratory factor analysis, confirmatory factor analysis and structural model were used. The result showed that consumer's perceived switching costs consisted of three factors: relationship cost, search cost and benefit loss cost. In estimated structural model, the relationship cost was influenced by leisure browsing; the search cost was influenced by informational browsing and leisure browsing; the benefit loss cost was influenced by leisure browsing. Especially, the leisure browsing was the most highly related to the benefit loss cost, and followed by relationship cost and search cost. However, hedonic browsing was not significantly related the factors of switching costs. The search costs significantly affected customer's intentions for site retention. A managerial implication was discussed for e-retailers in order to develop strategic switching costs in building long-term relationships with web browsers on the apparel shopping websites.

방위사업 원가산정 업무를 민간 용역기관에 아웃소싱한지 4년이 경과되었다. 객관성과 신뢰성이 다소 향상되었지만, 용역기관이 원가산정한 결과를 공무원이 다시 검토하는 등 시간과 비용만 더 든다는 부정적 시각도 일부 존재하였다. 따라서 본 연구를 통해 방위사업 원가산정 아웃소싱 수행간 발생할 수 있는 리스크 요인을 식별하여 중요도 우선순위를 분석해 중요도에 따른 리스크 대응방안을 강구하고자 한다. 향후 원가산정 아웃소싱간 사전 리스크 관리를 함으로써 적정 원가산정으로 원활한 군수품 조달로 군 전투력 향상, 방산업체 적정 이윤 보장 및 국방 예산절감에 기여하기 위함이다.

목적 많은 사용자들이 스마트폰을 바꾸고 있지만 대부분의 경우 새로운 스마트폰으로 바꾸는 대신 기존에 가지고 있는 스마트폰을 계속 사용하려는 경향이 있다. 브랜드 충성도와 전환비용은 기존의 스마트폰을 계속 사용하는 경향을 결정하는 요인이다. 다음과 같은 연구문제를 제기한다. "새로운 스마트폰을 구매하는데 있어서 브랜드 충성도와 전환비용의 역할은 무엇인가?" 방법론 기존 브랜드를 계속 사용하려는 경향을 고려하여 새로운 스마트폰 구매의도를 설명하기 위한 여섯 개의 가설을 제안했다. 연구모형은 177명의 대학생을 대상으로 LG의 G4 스마트폰을 구매의도에 대해 실증적 검증을 하였다. PLS에 의해 자료 분석을 한 결과 모든 가설이 통계적으로 지지받았다. 결과 첫째, 기존 스마트폰에 대한 브랜드 충성도와 전환비용은 새로운 스마트폰 구매에 영향을 미친다. 둘째, 브랜드 충성도는 전환비용과 상대적 이점의 관계에서 조절변수 역할을 한다. 셋째, 지각된 심미성과 가격 가치도 스마트폰 구매에 영향을 미친다.

손상 사고 중독과 관련해 환자의 의료비 증가는 국가건강보장체계의 지속가능성을 제고하기 위한 중대한 과제이며, 제도의 개선이나 건강보험의 관리 운영 효율화를 통한 의료비 증가를 억제할 필요가 있다. 따라서 손상 발생과 사망률이 높은 우리나라에서 손상 문제를 사회적으로 강조하기 위해서는 손상의 사회경제적 비용을 추계하는 것이 필요하다. 본 연구는 2008년도 한국의료패널 조사 중 외래 손상 사고 중독 환자를 대상으로 이용실태와 의료비지출을 전반적으로 파악하여, 손상으로 외래 서비스 이용 시 환자의 직접비용과 생산차질 등으로 인한 생산손실비용을 추계하였고, 궁극적으로 손상의 사회경제적 손상 비용을 추계하였다.

A system subject to random shocks is considered. The shocks arrive according to a Poisson process and the amount of each shock is exponentially distributed. In this paper, a periodic inspection policy for the system is compared with a random inspection policy. After assigning several maintenance costs to the system, we calculate and compare the long-run average costs per unit time under two policies.

The objective of this study is to evaluate the effects of sharing uncertain yield information with a downstream supply chain player. We are interested in understanding how the amount of yield uncertainty affects the supply-side benefits and/or costs, which has not been considered in the literature, in addition to the customer-side benefits. With that purpose, this work evaluates a supplier who provides yield information in comparison with another supplier who shares no information. We simulate an order-up-to type heuristic policy that is adapted from the literature and reasonably modified to represent yield information sharing with error. From the simulation study, we argue that the customer would experience cost reduction, but the cost for supplier's inventory is increasing when sharing yield information. Furthermore, the amount of benefits and costs are situational and affected by level of yield uncertainty and demand variance. Based on the simulation study, we finally make several recommendations for the supply-side approaches to yield information sharing.
