This study examined the characteristicso f the knowledge discovery and data mining algorithms to demonstrate how they can be used to predict health outcomes and provide policy information for hypertension management using the Korea Medical Insurance Corporation database. Specifically this study validated the predictive power of data mining algorithms by comparing the performance of logistic regression and two decision tree algorithms CHAID (Chi-squared Automatic Interaction Detection) and C5.0 (a variant of C4.5) since logistic regression has assumed a major position in the healthcare field as a method for predicting or classifying health outcomes based on the specific characteristics of each individual case. This comparison was performed using the test set of 4,588 beneficiaries and the training set of 13,689 beneficiaries that were used to develop the models. On the contrary to the previous study CHAID algorithm performed better than logistic regression in predicting hypertension but C5.0 had the lowest predictive power. In addition CHAID algorithm and association rule also provided the segment characteristics for the risk factors that may be used in developing hypertension management programs. This showed that data mining approach can be a useful analytic tool for predicting and classifying health outcomes data.

What are some of the explanations for cross-national diversity of foresight performance among technological followers? Why are some countries more successful than others in learning how to develop national innovation system foresight? This paper argues that the answers are linked to organizational capacities at three different levels: governmental, policy network and social learning. To corroborate this argument, the paper chose Iran and Korea as benchmarking partners, and attempts to find out what makes Iran a slow learner in building innovation system foresight. The conceptual model is an improved model of Saritas's, by integrating Borras' and Andersen's conceptions and classifications. The data are collected from comprehensive interviews in both countries and second-hand data of international indexes. The paper, finally, concludes that it is the weakness of analytical-systemic capacity that impedes and delays the emergence of systemic foresight in Iran, and that this weakness stems from the adverse impacts of the dominant institutions, surrounding the innovation system. The final point is that it is not sufficient for Iran to learn the methods and techniques of foresight from Korea. It should learn how to open its macro-policy towards the global market and design appropriate industrial strategy in a coherent policy-strategy portfolio.

A variety of approaches are being applied to improve the existing ex-ante evaluation by expert panels in publicly funded R&D. While the objective evaluation criteria are constantly being improved to screen and select the superior projects, alternative approaches such as random prioritization and logical modeling are also underway to overcome the conservative bias of reviewers and to secure disruptive innovation. This study intends to find critical implications for ex-ante evaluation of public R&D system from the comparison of Indonesia and Korea. For the comparative analysis, literature review and expert in-depth interviews are conducted on the national R&D system and the selection evaluation process. In Korea, the selection criteria of projects are legally promulgated for establishing an objective evaluation system, and at the program level, the major considerations in the planning process are specified by Presidential Decree. On the other hand, while Indonesia conducts R&D in 47 strategic fields largely by public research institutes (PRI) based on the non-competitive government contributions. This study draws out implications of institutionalizing the planning process at the level of program, and of increasing the ratio of contract-based competitive funding at the level of project in the national R&D portfolio.

The purpose of this study was to compare smoking control strategies between Korea and the United States. Korea and other developing countries may learn from the experience of the United States in dealing with the growing epidemic of cigarettes. In particular, smoking control objectives, structures, laws and regulations, funds, programs and activities, research, and surveillance systems were compared. The comparison was conducted at the federal, states/provincial, and county levels of the two countries. The data were collected through various governmental websites, contact with people directly, and a literature review. Based on the comparison, seven recommendations for smoking control strategies were made primarily for Korea.

본 연구는 소년보호처분을 받은 비행청소년과 일반 중 고등학교 남학생들의 자아존중감과 사회성에 대한 영역별 차이를 비교분석해 보고, 청소년비행 예방을 위한 교정 정책방안 모색을 목적으로 한다. 대전시에 소재하고 있는 소년원생(84명)과 일반 중 고등학교의 남학생(230명)을 설문조사하였다. 분석결과, 자아존중감 차이분석에서는 총체적 자아존중감과 학교 자아존중감에서 비행청소년이 높게 나타났으나, 가정적 자아존중감 영역에서만 일반청소년이 높은 결과를 보였다. 사회성의 하위 영역의 지도성에서는 비행청소년이 높은 결과를 보였고, 자주성과 협동성에서는 일반청소년이 높게 나타났다. 결론적으로 각 개인의 특성과 환경에 따라 자아존중감과 사회성의 차이는 영역별로 다르게 나타나기 때문에, 맞춤형 설계를 통한 비행예방 교정정책의 방안이 효과적임을 시사하는 바이다.

PURPOSE: Focusing on the factors that influence the infectious disease emergency response policy (approached by dividing the factors into health policy management and economic policies), both SARS and MERS cases were based on the legal system, manpower, and budget, but there has not been enough learning from the epidemic. This study focused on infectious disease emergency governance, which various studies have neglected despite its social and academic importance. METHODS: The research is based on an analysis of SARS, MERS, and COVID-19 and compares global policies. In this study, infectious disease emergency governance was divided into health policy management and economic factors. This study focused on planning and leadership before and after the outbreak of infectious diseases and how cooperation was achieved to monitor and respond to infectious diseases successfully. RESULTS and CONCLUSION: The limit of this study was that COVID-19 is a currently ongoing infectious disease with high uncertainty. Because it is an ongoing problem, only some data and statistics are reflected, and many limitations prevent a proper comparison under the same criteria as other infectious diseases. In addition, because continuous changes are expected, there is also room for infectious diseases to develop in a completely different pattern from the current situation, and continuous research must be accompanied in the future.

In many distribution systems important cost reductions and/or service improvements may be achieved by adopting an efficient inventory policy and proper selection of facilities. These efficiency improvements and service enhancements clearly require an integrated approach towards various logistical planning functions. The areas of inventory control and transportation planning need to be closely coordinated. The purpose of this paper is to construct an integrated model that can minimize the total cost of the transportation and inventory systems between multiple origin and destination points, where in origin point i has the supply of commodities and in destination point j requires the commodities. In this case, demands of the destination points are assumed random variables which have a known probability distribution. Using the lot-size reorder-point policy and the safety stock level that minimize total cost we find optimal distribution centers which transport the commodities to the destination points and suggest an optimal inventory policy to the selected distribution center. We also show if a demand greater than one unit will occur at a particular time, we describe the approximate optional replenishment policy from computational results of this lot-size reorder-point policy. This model is formulated as a 0-1 nonlinear integer programming problem. To solve the problem, this paper proposes heuristic computational procedures and a computer program with UNIX C language. In the usefulness review, we show the meaning and validity of the proposed model and exhibit the results of a comparison between our approach and the traditional approach, respectively.

차등서비스 네트워크의 AF(Assured Forwarding) 서비스에서 TCP 트래픽을 위한 기존 marking policy 연구는 TCP 트래픽의 RTT(Round Trip Time), 목표 전송률(target rate) 영향 등에 대한 고려가 부족하였다. 본 논문에서는 TCP 트래픽의 RTT의 영향에 의한 낮은 공평성을 개선하기 위하여 평균 전송률 예측 기반에서 TCP flow의 상태 정보를 이용한 개선된 TSW3CDM_FS(Time Sliding Window Three Color Dynamic Marker) 알고리즘을 제안한다. 제안한 알고리즘은 목표 전송률에 비례한 대역분배를 하기위한 dynamic marking policy 알고리즘이다. 제안된 알고리즘의 성능평가를 위하여 네트워크 시뮬레이터(NS-2)를 이용하여 컴퓨터 시뮬레이션을 수행하였다. 시뮬레이션 결과 제안한 TSW3CDM 알고리즘의 공평성이 기존의 TSW3CM 방식에 비해 향상된 결과를 보였다.
