Purpose: The purpose of this study was to examine symptoms, mood and sleep disturbance in patients with hemodialysis. Method: A sample of 96 hemodialysis patients participated. Data were collected using symptom scale of hemodialysis patients, profile of mood state and the sleep scale. Statistical analytic methods included t-tes, ANOVA and Pearson correlation analyses. Results: Patients with spouse/partners experienced significantly less symptoms than those with no spouse (F=6.29, p=.003). Mood disturbance was not significantly correlated with age; but older patients experienced higher sleep disturbance (F=4.88, p=.010). Symptoms, mood and sleep disturbance are significantly related with each other. Conclusion: It is important to assess symptoms, mood and sleep disturbance in older hemodialysis patients with no spouse. It is needed to repeat extensive study and comparative study with other population in order to define clearly.

In this study, the static and dynamic characteristics of endmilling process was modelled and the analytic realization of chatter mechanism was discussed. In this regard, We have discussed on the comparative assessment of recursive time series modeling algorithms that can represent the machining process and detect the abnormal machining behaviors in precision endmilling operation. In this study, simulation and experimental work were performed to show the malfunctional behaviors. For this purpose, new recursive(RLSM) were adopted for the on-line system identification and monitoring of a machining process, we can apply these new algorithms in real process for detection of abnormal chatter. Also, the stability lobe of chatter was analysed by varying parameter of cutting dynamices in regenerative chatter mechanics.

The purpose of this study is an overall valuation about propriety study of school facilities BTL(Build-Transfer-Lease) by means of AHP(Analytic Hierarchy Process). The search point includes these questions. Is BTL of school facilities a reasonable project for school, or is the former government financial project on the position of comparative superiority? And, is a partial BTL possible as an alternative plan? The result of this study shows that preference rate about BTL is 39%, that of former government financial project is 32%, and that of partial BTL is 29%.

In general, every welfare state is to be productive. If not, the welfare state itself cannot be sustainable because resource for the development of welfare only comes from a sound level of economic development However, how to mix welfare and production differs from country to country. This article tackles this phenomenon as a starting point. Granted, contemporary studies of comparative welfare state often starts from the theory of welfare regime which has been suggested by Esping-Andersen. This article also regards the framework as an analytic tool to elaborate upon the concept of productive welfare and to categorize different types of conception of productive welfare. In liberal regime, the concept is so narrowly interpreted that they emphasize micro-efficiency of specific welfare programs. On the contrary, the other two regime types recognize the concept of productive welfare as relatively wide. Therefore, conservative and social democratic regimes underscore macro-efficiency of the welfare state as a whole. Empirical analyses of this article explores each regime's success and failure in terms of achieving fundamental goals of the welfare state, i.e. economic development and enhancement of equality. A series of evidence show that liberal regime fails in achieving both goals, while the other two regimes seem to be relatively successful. In conclusion, it may be pointed out that current tendency of neo-liberalism and anti-welfarism in Korea should be overcome, which must be the prime task of social welfare academia of this country.

Based on Nisbett and his colleagues' theoretical model "Holistic" and "Analytic" which show the differences in cognitive style of Eastern Asian and Westerners, the author hypothesized that the differences in cognitive style of people from diverse cultural backgrounds may influence their perception and usage of webpage. An experiment was carried out and the Eye-gaze device was used to assist to explore the relationship. The results revealed the relationship between cognitive style and webpage design. different cognitive style results different viewing pattern on webpage. Chinese people are more likely to have a holistic view of the whole page first and then focus on detail, while French people tend to read the heading information first and then proceeding down the page. Chinese emphasized the background as well as the whole look and feel of the webpage more, while French noticed the independent contents and element designs more on the webpage.

An experimental modeling of cutting and structural dynamics and the on-line detection of malfunction process is substantial not only for the investigation of the static and dynamic characteristics of cutting process but also for the analytic realization of diagnostic systems. In this regard, We have discussed on the comparative assessment of two recursive time series modeling algorithms that can represent the machining process and detect the abnormal machining behaviors in precision round shape machining such as turning, drilling and boring in mold and die making. In this study, simulation and experimental work were performed to show the malfunctioned behaviors. For this purpose, two new recursive approach (REIVM, RLSM) were adopted fur the on-line system identification and monitoring of a machining process, we can apply these new algorithm in real process for the detection of abnormal machining behaviors such as chipping, chatter, wear and round shape lobe waviness.

An analytic and comparative study on the level of concentration on heavy metals in silt of Han- River was described. The Paldang lake supplies tap water resources for the 20 million residents in the metropolitan zone. It is composed that three steps for water works by the water volume in all 35,072 thousand tons : the first section is 7,251 thousand tons, the second is 15,980 thousand tons and the third is 11,841 thousand tons. However, recently it has becoming a serious social issue for water contamination on Paldang by heavy metals due to gathering of silt. It has concentrated on analysis and comparison study on the level of heavy metals between contamination- estimated zone and the other zones. After all, Concentration on heavy metals of expected none pollute's zone and expected pollute's zone indicate almost similar results. In the end, heavy metals within silt of Han- River consider not to effect on pollution but quantity of natural condition.

I have focused my study on the comparative analysis between 'Sacrestia Vecchia (Old sacresty)' and 'Sacrestia Nouva (New sacresty)' of San Lorenzo in Firenze. One is designed by F. Brunelleschi and the other is designed by B. Michelangello on the base of similar program and context. The analytic study has led me to the following conclusions: First. two saresties take concrete shapes by organizing the classcal vocabularies on the elementary forms. Second, though Michelangelo has started Bruneleschi's sacresty, he gives a more concrete form by the heightening the section. Third, the transformation of entrance and aediclues show that Michelangelo designed the new sacresty on the creative interpretation of the classical vocabulary and the context.

생산입지의 결정으로 인한 투자, 생산 및 마케팅에 이르기까지 사업의 성과에 미치는 영향은 장기간 지속되기 때문에 합리적인 의사결정이 매우 중요하다. 특히 우리가 잘 알지 못하는 지역에서의 생산입지는 더욱 체계적이고 합리적인 방법을 적용할 필요가 있다. 본 실증연구의 대상 지역인 중국은 2050부터 미국을 앞지르는 세계최대의 경제대국을 표방하고 있는 상황임을 감안할 때, 수출의존도가 매우 높은 한국으로서는 대중국 직접 투자에 대한 연구가 매우 필요하다고 볼 수 있다. 본 논문에서는 생산입지선정에 대한 선행연구에서 중요요인으로 고려된 바 있는 요인들을 정리하고, 한국 및 중국의 기업인들 및 전문가들에 의한 브레인스토밍(brain storming)방식의 설문을 통해서 평가 항목 대상들을 선정하였다. 생산입지 결정을 비롯한 다양한 분야에서 활용되고 있는 계층분석과정(AHP: Analytic Hierarchy Process)을 이용하여 양국 기업인들 간 생산입지선정 시 고려하는 요인들에 대한 중요도 인식에 차이가 있는지 실증적으로 규명하기 위해서 중국의 상해 및 심양 지역을 대상으로 실증적인 연구를 하였다.
