The paper discusses technology platforms as an instrument of science, technology and innovation policy in light of their use in industrial R&D. The authors assert that the technology platforms approach as a policy concept refects special organizational and institutional features learned from industrial technology platforms. The characteristics of industrial technology platforms are reviewed, and their impact on the organization of research, development and innovation activities in companies is explored. Second, the industrial technology platform is examined in the context of European Technology Platforms and the recent initiative for technology platforms in Russia. Finally, the technology platform concept implications for the STI policy context are discussed.

As for M/G/1 queueing system, we use various control policies, with which we can optimize the system. Up to now the most widely adopted policies are N-Policy, T-Policy, D-Policy, and so on. The existing researches are largely concerned to find an optimal operation condition or to optimize the system under single policy in M/G/1 system. There are, however, few literatures dealing with multiple control policies at once to enhance the flexibility of the model. In this study, we consider M/G/1 system adopting N-Policy and T-Policy simultaneously. If one of two conditions is satisfied, then, the server starts the service. We call this Min(N,T)-Policy. We find the probability distribution of the number of customers and mean waiting time in steady state and derive a cost function. Next, we seek the $N^*$, optimal threshold under various N values. Finally, we reveal the characteristics of cost function.

Taxes are levied in almost every country, primarily to raise revenue for government expenditures. This study explores factors influencing tax compliance of small- and medium-sized enterprises (SMEs) in Vietnam. Data from 376 SMEs, who are business taxpayers, were collected through a researcher-administered questionnaire survey method. The results indicate that six groups of factors have significant impacts on tax compliance among Vietnamese SMEs. These groups include: Business characteristics (BC), Characteristics of accounting practices within organization (AP), Awareness of tax obligations (TO), Tax policy (TP), View on tax compliance (TC), and Probability of tax examination on taxpayer compliance (TE). Multivariate analysis was adopted; Cronbach's alpha coefficients were calculated, then, Exploratory Factor Analysis (EFA) was used. The findings show that, among these six factors, the most influential is Characteristics of accounting practices (AP). Thus, it is recommended that tax agencies should help SMEs improve their accounting skills and increase their knowledge by organizing training workshops and short courses on taxation. SMEs also need to have an adequate accounting system in accordance with principles and standards prescribed by the Tax Law. It is expected that this study can provide important insights and understandings to policy-makers, practitioners, academicians and other regulatory authorities in tax policy formulations.

In order to balance with supply policy, public housing management and operation policies have been implemented in terms of housing welfare, but citizens have not yet achieved the results that the citizens are experiencing. The purpose of this study is to analysis the residential satisfaction of the including the housing performance through the characteristics of the public housing residents in Seoul. The data used in this study is based on the survey data of public housing panel survey in Seoul (2016). The study method used ordered logistic regression analysis based on the fact that dependent variables appeared as ordered responses. Major research results are as follows. Firstly, housing performance and residential satisfaction may not match. Even though the satisfaction of housing area, type, and management fee is high, satisfaction with residential environment is low if commuting distance, the number of small libraries, and hospitals are small. Secondly, it showed different characteristics of residential environment factors among types of public housing. Rather than focusing on supply, customized supply is needed considering characteristics of public housing types. Thirdly, the policy for public housing needs to be realized by a fair policy on the residential environment. It is necessary to contribute to better housing stability as a customized policy considering the local residential environment.

Items are assumed to fail by degradation. An appropriate stochastic model of such item is a cumulative process in which an item can fail only when the total amount of wear exceeds a prespecified failure level. This paper presents replacement policy in which an item is replaced at a certain level of wear before failure or at failure, whichever occurs first. Yet, when measuring the item wear level is very expensive, destructive or time-consuming, it may be economical to use substitutive characteristics that are correlated with the item wear level and relatively inexpensive to measure. The item's wear level could usually be estimated by monitoring such substitutive characteristics only except for a breakdown, which may be observed immediately at its occurrence. The purpose of this paper is to find an optimal periodic replacement policy based on such substitutive characteristics that balance the cost of replacement with the cost of failure and result in a minimum total long-run average cost per unit time. The optimal level of substitutive characteristics to replace the item is obtained. Numerical example illustrate how the model can be used to determine the optimal replacement policy.

Purpose : This study attempted to find out the relationship between leadership style, knowledge transfer in nursing officers' job, considering the task characteristics. Methods : The data were collected from the military hospital during November 1st to November 17th, 2008 using a structured questionnaire and analyzed with the statistical method of frequency, correlation, and regression analysis, in SPSS 12.0 program package. Results/Conclusion : The results of empirical analysis shows that the levels of job tension and job focused task domain affect the job characteristics of the nursing officers' organization. The job characteristics have a moderating effect on the relationship between leadership style and knowledge transfer. The research is very useful in finding out the job characteristics which well depict military nursing organizations. This research suggests that a desirable leadership styles affect the knowledge transfer in the job characteristics type.

The objective of this paper is to provide an improved reorder decision policy for general multi-echelon distribution systems utilizing the shared stock information. It has been known that traditional reorder policies sometimes show poor performance in distribution systems. Thus, in our previous research we introduced the order risk policy which utilizes the shared stock information more accurately for the 2- echelon distribution system and proved the optimality. However, since the real world supply chain is generally composed with more than 2 echelons, we extend the order risk policy for the general multi-echelon systems. Since the calculation of the exact order risk value for general multi-echelon systems is very complex, we provide two approximation methods for the real-time calculation. Through the computational experiment comparing the order risk policy with the existing policies under various conditions, we show the performance of the order risk policy and analyze the value of the shared stock information varying with the characteristics of the supply chain.

Legislation on pharmaceutical reimbursement decision using economic evaluation results was made in Korea in fm, but has yet to be fully implemented. We evaluated the quality of Korean economic evaluation studies of pharmaceuticals to understand gaps between legislation and implementation. From this evaluation, we propose policy options that might strengthen the research Infrastructure In order to support such studies. We reviewed 23 published studies for drugs conducted between 1996 and 2004. Evaluation criteria included methodological characteristics, healthcare system characteristics, population characteristics, and applicability of results. Large variation in study quality was observed, particularly with study design, outcome data, treatment patterns and interpretation. Korean clinical data used was mostly from observational studies of 1-2 hospitals. Foreign data was extracted from clinical trials that did not Include Asian population and their selection criterion was not clarified. With respect to treatment patterns, medical records and hospital bills were used without adjustment regarding area, hospital type, and others. And next frequent situation relied on expert opinion from academic physicians in specialty practice. preference measures, when used, were not elicited from the Korean population. $78.3\%$ of studies did not clarify the funding source. If the Korean economic evaluation policy is to provide meaningful data for decision makers, the quality of cost-effectiveness studies will need to improve dramatically. This may involve access to or creation of better data, more diverse funding, unproved training of researchers and evaluators, and partnerships with technology manufacturers.

본 논문은 IPTV 서비스의 수용과 확산을 위한 바람직한 정부의 정책 프레임워크를 분석하여 제시하고 있다. 지금까지 대부분의 연구들은 소비자 측면에서 개인적인 IPTV 서비스 수용과 확산에 국한되어져 있었기 때문에 조직관리적인 측면에서의 분석이 미흡한 실정이다. IPTV 서비스가 활성화되기 위해서는 다양한 정부의 지원정책 등이 필요하기 때문에, 본 연구에서는 개인 상황에서의 혁신 속성 이론과 조직 상황에서의 실행 프로세스 이론을 적용하였다. 즉 개인의 혁신성이 높은 경우에는 혁신의 속성들이 IPTV 서비스 수용에 더 큰 영향을 미치며, 혁신 관리 측면에서는 정책적 기대가 높은 상황에서 IPTV 관리 속성들이 수용에 더 큰 영향을 미칠 것으로 판단하였다. 본 연구의 결과 개인의 혁신성이 높을수록, 그리고 이와 함께 정부 정책에 대한 기대가 클수록 혁신의 속성 및 IPTV 관리 속성 모두가 IPTV 수용의도에 미치는 영향력이 높아지기 때문에, 정부 정책은 개인의 혁신성을 자극하면서 정책기대를 높이는 방안이 바람직한 것으로 분석되었다.
