In the conduct of this study, a web-enabled healthcare system for the management of hypertension was implemented through a hyperlink-based inference approach. The hyperlink-based inference platform implemented using the hypertext capacity of HTML which ensured accessibility, multimedia facilities, fast response, stability, ease of use and upgrade, and platform independency of expert systems. Many HTML documents, which are hyperlinked to each other based on expert rules, were uploaded beforehand to perform the hyperlink-based inference. The HTML documents were uploaded and maintained automatically by our proprietary tool called the Web-Based inference System (WeBIS) that supports a graphical user interface (GUI) for the input and edit of decision graphs. Nevertheless, the editing task of the decision graph using the GUI tool is a time consuming and tedious chore when the knowledge engineer must perform it manually. Accordingly, this research implemented an automatic generator of the decision graph for the management of hypertension. As a result, this research suggests a methodology for the development of Web-enabled healthcare systems using the hyperlink-based inference approach and, as an example, implements a Web-enabled healthcare system for hypertension, a platform which peformed especially well in the areas of speed and stability.

The purpose of this study is to investigate the effects of factors of family leisures on family intra-system dynamics and quality of family life. A total 309 questionnaires was analyzed from married men and women of school-age families. Factors of family leisures were classified in 'education oriented', 'hobby oriented', social oriented'and 'family oriented'in the study ahead.(Refer to Journal of korean Home Management association Vol. 19(2).) The major results of this research were as follows. First, family intra-system dynamics was classified 'individual progress', 'sentimental stability','interaction'and 'management efficiency'. Second, the group that participated more in 'social oriented'and less in 'family oriented'activities had higher level of 'individual progress'. The group that participated less in 'social oriented'and more in 'education oriented'activities had higher level of 'sentimental stability'The group that participated more in 'education oriented'activities had higher level of 'interaction'and 'management efficiency '. Based on the results as above, we suggest people need to overcome 'a mental panic'through the family leisure. And we need to develop concern with family leisure as a practical loaming.

이 연구는 '콘크리트 테스트 해머'를 이용하여 1990년대에 경기도와 강원도에서 시공된 사방댐 중 사방협회 에서 육안 점검한 사방댐 10기(양호 6기, 불량 4기)의 대수면, 방수로 및 반수면의 반발경도 측정을 통해 사방댐의 안정성을 파악하여 사방댐의 비파괴검사에 적합한 압축강도 추정식과 적정 판정범위를 정하는 것을 목적으로 진행하였다. 특히, 콘크리트 사방댐 본체의 안정성을 사전에 파악하게 되면 사방댐을 적시에 보수, 관리할 수 있고, 사방댐 본연의 기능인 토사유출방지기능을 최대화할 수 있다. 콘크리트 사방댐의 압축강도 조사한 결과, 현재 사방협회에서 진행 중인 안정점검 육안 점검 결과와 대부분 일치하였다. 또한, 안정점검시 압축강도는 일본건축학회에서 제시한 추정식을 적용하는 것이 적합할 것으로 판단되었으며, 판정 기준은 300 $kgf/cm^2$ 이상일 경우에는 '안정', 250~300 $kgf/cm^2$이 범위일 경우에는 '정밀검사 필요', $kgf/cm^2$ 미만일 경우에는 '불량' 판정을 내리는 것이 적합하다고 사료된다. 그리고 사방댐의 연대별 압축강도에 대한 자료를 충분히 축적하고, 이를 토대로 우리나라 사방댐에 적합한 안정기준과 압축강도 추정식이 필요하다고 사료된다. 앞으로는 육안 점검과 간이 안정성 검사를 통해 사방 구조물에 이상이 발견될 경우 정밀진단 검사를 실시하여 안정도를 파악하는 체계가 구축되어야 할 것이다.

본 연구는 조경시공 및 관리분야에서 수목관리, 전지 등과 같은 고소부위 작업을 위해 주로 사용하는 삼각지지형 이동식 사다리의 전도 안정성을 평가한 것이다. 산업현장에서 사용 빈도가 높은 이동식 사다리에 포함되는 삼각지지형 이동식 사다리는 작업 특성에 따라 바닥지지 형태가 일반적인 A형의 사면지지가 아닌 삼각지지 방식이고, 작업 높이도 이동식 사다리와 비교하여 2배 이상 높기 때문에 떨어짐과 함께 작업자의 안전을 위협하는 전도 발생 가능성이 매우 높다고 할 수 있다. 따라서, 국내에서 사용되고 있는 삼각지지형 이동식 사다리를 대상으로 관련 기준인 ANSI-ASC A14.7과 EN 131-Part 7에서 규정하고 있는 전도 안정성 평가를 기반으로 하여 작업 높이에 따른 전도모멘트와 저항모멘트를 계산할 수 있는 수식을 각각 유도하여 계산한 후, 이 값을 상호 비교하여 전도에 대한 안전율 및 전도 방향에 따른 안정성을 평가하였다. 각 기준에 따른 전도 안정성 평가 결과, EN 131-Part 7의 규정을 적용하면 후면방향 8단과 측면방향으로 6단 이상의 삼각지지형 이동식 사다리는 전도에 대해서 불안정한 것으로 평가되었으나, ANSI-ASC A14.7의 규정에 의하면 방향에 상관없이 모든 단수에서 전도에 대한 안정성을 확보하고 있는 것으로 평가되었다.

It is urgent to redevelop the superannuated reservoir levee through the levee raising for countermeasure to climate change and improvement of storage capacity of reservoir. However, low compaction degree of the raised reservoir levee owing to poor construction condition leads to degradation of the stability of the reservoir levee on seepage and earthquake. In this study, seepage and seismic behavior of raised reservoir levee with low compaction degree was evaluated through numerical simulation. From the simulated results, water level raising possibly induces crack and/or sinkhole on the surface of the poorly-compacted raised reservoir levee owing to the increase of the subsidences at the crown and the front side of that. In addition, relatively larger displacement and acceleration response at the front side of raised reservoir levee in seismic condition may degrade overall stability of reservoir levee. Therefore, reasonable construction management for the compaction of the raised reservoir levee is required for ensuring long-term stability on seepage and earthquake.

We investigated the effects of trunk twist on postural stability during manually handling flat ties. Ten male subjects participated in this study. While handling 5kgf and 10kgf bundles of flat ties respectively, their centers of pressure (COPs) were measured under two levels of body position (twisted and fixed), two levels of direction (left and right), and three levels of object position ($30^{\circ}$, $45^{\circ}$, and $60^{\circ}$). Subjects' postural stability was quantified by calculating the sway length. Results showed that the effect of different object position was significant on postural sway length in subject's medio-lateral axis. Post-hoc multiple comparions revealed that, under the 5kgf load condition, the sway length was increased significantly as the object position increased to $45^{\circ}$. Under the 10kgf load condition, however, the sway length was increased significantly at the object position of $60^{\circ}$. Actual or potential applications of this research include guidelines for the design of working posture evaluation techniques.

In this study, we empirically examine the impact of win-win growth effort of domestic large firms on their financial performance. Specifically, we classify the financial performance into three aspects such as profitability, stability and efficiency, select corresponding financial ratios to each aspect, and analyze the causal relationship between the firms' win-win growth effort and each of the financial ratios. In addition, we figure out the impact of the firms' win-win growth effort on their stock rate of return. From the analysis, we show that the win-win growth effort has a positive impact on the firms' profitability, stability and stock prices; however, it does not give statistically significant impact on the firms' efficiency with even negative impact on it. These results imply that the firms' win-win growth effort could bring about inefficiency in their business operations, but the effort could increase the firms' profitability and make their financial structure more stable. Furthermore, the effort could enhance the firms' image of leading CSR (corporate social responsibility), which in turn increase their stock values.

This study was performed to develop the basic framework of multicultural art education programs for female foreign immigrants married to Korean males. First, these programs aim to lessen their cultural variance in acculturizing in Korea, and thereafter enhance their emotional stability and improve their creative ability to integrate cultural diversity into family life. The primary objective of this study was to offer a suitable education program and evaluation criteria for the program; the research has been done through person-to person interviews with 53 subjects using a series of questionnaires composed of 8 five-point Likert-Scaled items. As for the process of the interview, the subjects were asked about their satisfaction with each program item twice in order to comparetheir impressions before and after program participation. The satisfaction scores were analyzed using frequency distribution. In addition, the program effects were also evaluated by coordinators and developers from their subjective comments through periodical evaluation meetings. From the results, it is observed that art education programs are beneficial for improving female immigrants' emotionaland cultural integration. In addition, experts determined that the programs were helpful for improving their human relationship and acculturization in Korea. Finally, it is concluded that multicultural education programs are a primary fundamental infra-structural way of integrating diverse cultures and improving communication exchanges, and therefore, improve family stability among the multicultural families in Korea.
