Although providing universal coverage for health care through the National Health Insurance(NHI) is a remarkable achievement, the issue of limited benefit coverage of the NHI has been at the core of national debate over how to improve its coverage. This study aims to evaluate benefit extension strategies and implemented policies with regard to the NHI since 1989 using 'policy window theory' proposed by John W. Kingdon. Understanding problem stream, policy stream, political stream, and coupling streams regarding the NHI, in particular benefit extension, would contribute to broaden policy debates and to develop more effective strategies for the future. Historically, political stream had opened policy window in the past two decades and policy streams can be characterized by three waves. Three streams have been coupled since 2003 and the government had a strong will to fulfill better performance of NHI coverage. Study findings indicate that identification of problem structure regarding NHI benefit was not connected with policy stream tightly. In addition, there has been limited discussion on policy goal and principles for extension coverage of the NHI. Policy strategies to improve coverage of the NHI should be linked to characteristics of problem and sought solutions under the principle which is expected to be sustainable through consensus in the society.

This study was aimed to examine problem-solving ability of fifth graders on two types of mathematical essay problems, and to analyze the process of mathematical justification in solving the essay problems. For this purpose, a total of 14 mathematical essay problems were developed, in which half of the items were single tasks and the other half were data-provided tasks. Sixteen students with higher academic achievements in mathematics and the Korean language were chosen, and were given to solve the mathematical essay problems individually. They then were asked to justify their solution methods in groups of 4 and to reach a consensus through negotiation among group members. Students were good at understanding the given single tasks but they often revealed lack of logical thinking and representation. They also tended to use everyday language rather than mathematical language in explaining their solution processes. Some students experienced difficulty in understanding the meaning of data in the essay problems. With regard to mathematical justification, students employed more internal justification by experience or mathematical logic than external justification by authority. Given this, this paper includes implications for teachers on how they need to teach mathematics in order to foster students' logical thinking and communication.

이 논문은 국제성인 역량프로그램(PIAAC) 자료를 바탕으로 교육에 따른 역량의 증진, 연령과 역량사이의 관계, 노동시장에서 역량의 수익률 등 세 측면에서 한국의 특징을 중심으로 국제비교를 시도한다. 실증분석 결과 한국은 교육수준에 따른 역량 차이가 크지 않고, 연령에 따른 역량의 감소 현상이 매우 두드러지며, 수리, 언어, 문제해결 중세 언어역량에 따른 수익률이 가장 높은 것으로 나타났다. 이는 많은 나라에서 수리역량에 대한 수익률이 가장 높은 것과는 비교되는 현상이다. 또한 한국은 문제해결 역량에 따른 수익률이 비교 대상 국가 중에 가장 낮으며 교육수준과 문제해결 역량 간의 상관관계도 가장 낮은 편에 속한다. 이러한 일련의 결과는 노동시장에서 역량을 축적할 수 있는 기회와 유인이 주어지는 시스템과 문화에 대한 고민이 교육시스템에 대한 관심 이상으로 필요하다는 점을 보여준다.

Science-Technology-Society curricula have been developed in several countries for the last 20 years. Those curricula were focused on social aspects of science, i.e., value-laden knowledge and scientific enterprise, and society-related scientific and technological issues, i.e., energy, pollution, natural resources. The major teaching models employed in those curricula were problem solving and decision making, which required the following teaching techniques: teacher as a manager, small group discussion, controversy as a motivational force for substantive learning, and sufficient factual information into the discussion. Further researches are to be made to ascertain whether or not the expectations of the curricula might be realized in practice. It was shown that most Korean biology teachers considered the STS-related goal of science education as more important than the other goals. Based upon the findings, some recommendations for development of Korean STS curriculum were made as follows: 1. The contents of the STS curricula are to be organized with the integrated mode; 2. The major teaching models throughout the contents are to be problem solving and decision making. These are considered to provide students with the opportunities to involve in debates on practical issues and to draw consensus from them; 3. Some degree of flexibility should be provided on teachers' implementation of the curriculum in terms of contents, teaching techniques etc.; 4. To increase the practicality of the curriculum, teachers should be involved in the development of the curriculum and the relevant research; and 5. Contents to be included in STS curriculum were suggested by some science educators, but the more systematic study is required in this respect.

An enterprise patch-management system (PMS) typically supplies a single point of failure (SPOF) of centralization structure. However, a Blockchain system offers features of decentralization, transaction integrity, user certification, and a smart chaincode. This study proposes a Hyperledger Fabric Blockchain-based distributed patch-management system and verifies its technological feasibility through prototyping, so that all participating users can be protected from various threats. In particular, by adopting a private chain for patch file set management, it is designed as a Blockchain system that can enhance security, log management, latest status supervision and monitoring functions. In addition, it uses a Hyperledger Fabric that owns a practical Byzantine fault tolerant consensus algorithm, and implements the functions of upload patch file set, download patch file set, and audit patch file history, which are major features of PMS, as a smart contract (chaincode), and verified this operation. The distributed ledger structure of Blockchain-based PMS can be a solution for distributor and client authentication and forgery problems, SPOF problem, and distribution record reliability problem. It not only presents an alternative to dealing with central management server loads and failures, but it also provides a higher level of security and availability.

Registration between image and object space is a fundamental step in photogrammetry and computer vision. Along with rapid development of sensors - multi/hyper spectral sensor, laser scanning sensor, radar sensor etc., the needs for registration between different sensors are ever increasing. There are two important considerations on different sensor registration. They are sensor invariant feature extraction and correspondence between them. Since point to point correspondence does not exist in image and laser scanning data, it is necessary to have higher entities for extraction and correspondence. This leads to modify first, existing mathematical and geometrical model which was suitable for point measurement to line measurements, second, matching scheme. In this research, linear feature is selected for sensor invariant features and matching entity. Linear features are incorporated into mathematical equation in the form of extended collinearity equation for registration problem known as photo resection which calculates exterior orientation parameters. The other emphasis is on the scheme of finding matched entities in the aide of RANSAC (RANdom SAmple Consensus) in the absence of correspondences. To relieve computational load which is a common problem in sampling theorem, deterministic sampling technique and selecting 4 line features from 4 sectors are applied.

The purpose of this study is to investigate the influences of demographic, personal and psychosocial variables on the wives' marital satisfaction in order to develop theories about the stablility of modern families. The data, collected from 490 mothers living in Seoul, is analyzed by statistical methods, such as Frequency Distribution, Pearson's Correlation, One-Way ANOVA, Scheffee-test and Multiple Regression Analysis. The major findings are as follows: 1) In my study, the Marital Satisfaction Scale consists of 7 dimensions; of which affective communication, problem-solving communication, and companionship are comparatively important variables. 2) Of demographic variables, wives' educational level is an influencing variable in 6 dimensions, and family monthly income, in general satisfaction. 3) Of personal variables, sex role attitude is a significantly influencing independent variable in satisfaction with children area and self actualization, variable in problem-solving communication area. 4) Of psychosocial variables, role enactment, role consensus, and role strain are proved to be influencing variables, but role salience is not. Also, role enactment is the most influencing independent variable in almost areas of marital satisfaction. 5) By given independent variables, variance is explained 30% of all. The implication that can be inferred from the above findings is that psychosocial variables are more important than demographic variables, and that personal variables such as androgyny, self-actualization should be encouraged to further research.

The relationship between H. pylori(Hp) infection and recurrent abdominal pain(RAP) in children is not clear. Current data in the literature regarding a causal relationship between Hp infection and childhood RAP are conflicting. However, meta-analysis and most of the recently published studies have not supported an association between Hp infection and an increased prevalence of abdominal pain. Most published studies have some problems and have been criticized on methodological grounds. Most of the existing studies have not been designed to include double-blind placebo controls. And, because of the low incidence of Hp infection in children, they have a problem of obtaining sufficient numbers of the Hp infected children. There is also a concern about the heterogeneity of testing methodology in the studies and diagnostic accuracy problems of the non-invasive tests such as low sensitivity of the serology tests and false positive results of the UBT in children. And conflicting results may be explained, in part, by the poor definition of RAP or dyspepsia for the study subjects. To date, no consensus exists for the treatment of Hp-infected children with RAP. Some authors suggest the clinical efficacy of Hp. But others suggest that eradication of Hp is not associated with improvement of RAP. The problem of the most treatment studies is that they had usually no control groups and the number of the subjects was small. In order to make reasonable decisions about treatment of Hp infection in children with RAP, long-term, randomized, double blind, well controlled studies in large numbers of children will be required.

Timoshenko beam model is widely exploited in the literature to examine the mechanical behavior of stubby beam-like components. Timoshenko beam theory is well-known to require the shear correction factor in order to recognize the nonuniform shear distribution at a section. While a variety of shear correction factors are appeared in the literature so far, there is still no consensus on the most appropriate form of the shear correction factor. The Saint-Venant's flexure problem is first revisited in the frame work of the classical theory of elasticity and a highly accurate approximate closed-form solution is presented employing the extended Kantorovich method. The resulted approximate solution for the elasticity field is then employed to introduce two shear correction factors consistent with the Cowper's and energy approaches. The mathematical form of the proposed shear correction factors are then simplified and compared with the results available in the literature over an extended range of Poisson's and aspect ratios. The proposed shear correction factors do not exhibit implausible issue of negative values and do not result in numerical instabilities too. Based on the comprehensive discussion on the shear correction factors, a piecewise definition of shear correction factor is introduced for rectangular cross-sections having excellent agreement with the numerical results in the literature for both shallow and deep cross-sections.
