This study aims to emphasize the importance of social inclusiveness for evaluation and future development of social policy in Korea. In particular, this study emphasizes that the future of social policy in Korea depends on the level of social inclusiveness. Social inclusiveness can be measured by the extent to which social policy is inclusive and the level of citizens' perception of social inclusiveness. This study uses 4 frameworks (universality, progressiveness, life-long, and adequacy) of inclusive asset-based policy to evaluate the level of social inclusiveness of key laws and social policies. Key findings are as follows: First, Korea has established normative systems of laws and social policies. Second, however, Korean social policy has multiple problems in universality, progressiveness, life-long, and adequacy. To enhance social inclusiveness of social policy, this study emphasizes the 'socialness' of social problems. Korea has faced market failure, the high level of rate experiencing poverty during life, and inefficiency of social policy. If we accept the socialness of social problems, social policy should attempt to increase publicness of social policy. The increase in socialness as well as social inclusiveness may be fundamental for inclusive society in Korea.

The purpose of this study is to examine which factors determine fall experience among Korean elderly. To achieve this purpose, it uses the Korean Longitudinal Study of Aging(KLoSA), wave 1 and 2. Participants aged 65 from wave 1 were selected. From wave 2, a dependent variable was selected and it was fall experiences since the first interview in 2006. Other than this variable, all independent variables were selected from wave 1. In analyses, x2 or t-test were conducted to examine whether independent variables significantly differ between falls and no falls. Then, since a dependent variable consisted of two categories-falls or no falls, multiple logistic regressions were run. Female, using hearing aid, having two diseases, having three or more diseases, depression, and exercise 5 times/a week or more elevated the odds ratios of fall experience. compared to their reference categories. Particularly, if Korean elderly had three or more diseases or depression, their likelihood of fall experience would have about 2 times higher than their reference categories. In conclusion, health practitioners should make the elderly be recognized how much these risk factors are important to falls. Also, Korean government should support Korean elderly having these risk factors to prevent them from falling.

In this study, the crack healing performance of each crack healing agent manufacturing method was analyzed by adding crack healing agents in the form of alginate gel and spore suspension inoculated with endospores of calcium carbonate-forming bacteria to mortar. In addition, by applying it to an full-scale structure in the form of a box-type culvert, we attempted to create an environment in which the developed crack healing agent can be applied not only to a laboratory environment but also to an actual field. The crack healing agent using the dry heat drying method showed crack healing performance, but in the case of the freeze drying method, many spores were killed by freeze hardening and therefore the crack healing performance was lost. As a result of SEM and XRD pattern analysis of the presumed crack healing material extracted from the crack of a full-scale structure, it was found to be calcite, one of the calcium carbonate crystals produced by microorganisms applied to the crack healing agent. In conclusion, it was found that the crack healing by microorganisms can be implemented in a real structure.

The purpose of the present study was to investigate middle grades (Grade 5-7) mathematics teachers' knowledge of partitive fraction division. The data were derived from a part of 40-hour professional development course on fractions, decimals, and proportions with 13 in-service teachers. In this study, I attempted to develop a model of teachers' way of knowing partitive fraction division in terms of two knowledge components: knowledge of units and partitioning operations. As a result, teachers' capacities to deal with a sharing division problem situation where the dividend and the divisor were relatively prime differed with regard to the two components. Teachers who reasoned with only two levels of units were limited in that the two-level structure they used did not show how much of one unit one person would get whereas teachers with three levels of units indicated more flexibilities in solving processes.

본고(本稿)에서는 다양한 형태의 금융충격(金融衝擊)의 거시경제효과(巨視經濟效果)를 분석하기 위해, 모든 금융충격(金融衝擊)을 통화의 지불수단으로서의 이용률(利用率)을 급격하게 변화시킴으로써 화폐시장(貨幣市場)에 초과수요나 초과공급을 초래하는 현상으로 이해하고, 동 충격을 유통속도충격(流通速度衝擊)과 통화승수충격(通貨乘數衝擊)으로 분리하여 그 규모를 추정할 수 있도록 전자(前者)는 은행의 예금회전율(預金回轉率)과 현금통화보유성향(現金通貨保有性向)에 의해, 후자(後者)는 현금통화보유성향과 지급준비보유성향에 의해 설명하는 일반적인 모형을 개발했다. 동 모형을 아용하여 80년대 이후 우리나라의 금융충격사례(金融衝擊事例)에 대해 분석한 결과는 다음과 같다. 82년 거액어음사기사건과 7.3조치에 의한 실명제예고조치(實名制豫告措置)는 M2를 3% 이상 감소시키는 효과를 초래하였으나, 실제로는 통화당국의 대응으로 오히려 3.0% 수준의 M2가 초과공급된 반면, 1988년의 금융실명제(金融實名制) 실시예고와 민간(民間)에 의한 1993년 8월 12일의 금융실명제실시예견은 M2를 각각 3.9% 및 4.9% 감소시키는 효과를 초래하여 정부의 통화공급대응(通貨供給對應)에도 불구하고 결과적으로는 각각 0.8% 및 0.6% 수준의 M2 과소공급을 초래한 것으로 추정되었다. 93년 8월 12일의 금융실명제 전격실시는 개략적으로 7~8%의 M2 통화량감소효과를 초래한 것으로 추정되지만, 실제로는 통화당국(通貨當局)의 신축적 통화공급으로 0.3~0.6% 정도의 M2 초과공급이 이루어진 것으로 추정되었다. 한편 본고(本稿)에서는 이와 같이 추정된 사례별 금융충격의 거시경제효과(巨視經濟效果) 시뮬레이션 결과(結果)도 같이 보여주고 있다.

Entering legal management, shareholders receive some payment. We call this phenomenon the deviations from absolute priority. This study focuses on incremental effect and determinants of equity to shareholders by wealth transfer from creditors to stockholders in the process of legal management. The main results of this study can by summarized as follows. First, the incremental effect of equity to shareholders is common in the sample of this study. The sample contains 46 non-listed firms that filed for legal management and had confirmed their reorganization plans. Second, the results of the regression model analyzing the determinants of incremental equity to shareholders in legal management show that it is negative related to the solvency(total debt/total asset), firm size, and weight of claims for secured creditors and banks significantly. but corporate reorganization period(from filing to confirmation)are not significant.

Under the 'Sustainability Paradigm', the building maintenance system is getting more important because more efficient maintenance means more sustainable building. This paper aims at improving present building maintenance system by comparing with the foreign developed countries' systems. The comparing countries are selected according to the level of building maintenance. As the results, 4 countries including USA, England, Germany, and Japan become the benchmark. The results show that building maintenance regulations are various by social, economic, and cultural characteristics. In addition, though building maintenance policy must be established, first of all, the related regulations and policy targets are prepared before the enforcement of maintenance regulation. The results provide some policy implications: 1. Building maintenance must be controled under the condition that a building can guarantee the safety of people and function of it. 2. Building maintenance system should contribute to the desirable urban environment and architectural culture.

A stochastic Markov process (MP) model has been developed for evaluating the probability of failure of the armor unit of rubble-mound breakwaters as a function of time. The mathematical MP model could have been formulated by combining the counting process or renewal process (CP/RP) on the load occurrences with the damage process (DP) on the cumulative damage events, and applied to the armor units of rubble-mound breakwaters. Transition probabilities have been estimated by Monte-Carlo simulation (MCS) technique with the definition of damage level of armor units, and very well satisfies some conditions constrained in the probabilistic and physical views. The probabilities of failure have been also compared and investigated in process of time which have been calculated according to the variations of return period and safety factor being the important variables related to design of armor units of rubble-mound breakwater. In particular, it can be quantitatively found how the prior damage levels can effect on the sequent probabilities of failure. Finally, two types of methodology have been in this study proposed to evaluate straightforwardly the repair times which are indispensable to the maintenance of armor units of rubble-mound breakwaters and shown several simulation results including the cost analyses.

International interests in chemical warfare agents (CWAs) have been increased recently because of the use of sarin (GB) in Syrian civil war which caused around 1,300 casualties in 2013. After exposing to natural environments, CWAs undergo hydrolysis or photodegrade to non-toxic degradation byproducts. Generally, CWAs and their degradation byproducts are present at very low concentration (e.g. several ppb), thus pretreatment processes including separation, extraction and concentration are required prior to any analyses. Liquid-liquid extraction and solid-phase extraction (SPE) are common techniques to pretreat environmental samples. Recently, a novel pretreatment method, liquid phase miecoextraction (LPME), has been applied to CWAs analysis, which could reduce amounts of solvent used but promote analytical efficiencies. Fundamental backgrounds of LPME and its application to CWAs analysis were reviewed.
