This study was carried out to identify the factors which correlated with upper limb function after stroke and to analyze the effect of related factors on upper limb function. The 100 stroke patients(MMSE-K>24) were participated. The upper limb function according to gender, hand dominance, stroke type, affected location, site of paralysis, speech disorder showed no significant difference, and show significant difference according to shoulder subluxation. The upper limb muscle strength(Manual Muscle Testing), proprioception, muscle tone(Modified Ashworth Scale), grip strength(Dynamometer), paint (Visual Analog Scale) showed significant correlations with upper limb function. These predictors explained 77.6% of the upper limb function and the most significant affecting factor of upper limb function was upper limb muscle strength. In conclusion, the upper limb muscle strengthening will be effective strategy to improving the upper limb function and considering the proprioception, muscle tone, grip strength, pain, subluxation will be helpful to develop the strategies.

This paper examined what factors affect the immediacy index showing the average number of times an article is cited in the year it is published. Not only Seventy-one immediacy indexes for subject field biology on JCR 2008 edition were gathered, but also many characteristics of scholarly journals that may influence the indexes directly or indirectly were aggregated. Simple correlation coefficient analysis, factor analysis, and regression analysis were performed on the paper. Therefore factors such as physical volume, availability, forthcoming issue, age and language explaining 67.64% of total variance were identified. After regression analysis using these factors as independent variables, the results were statistically significant. The results showed physical volumes, the total pages of publication, have an influence upon immediacy indexes obviously, although it is expected that journal reputations may affect immediacy indexes. Generally open access journals had high immediacy indexes. High ranked journals on immediacy index were apt to be issued frequently, uploaded very often on PMC, and published in major countries including United States and United Kingdom.

This paper proposes the smart emotion lighting control system of a mobile-based. The proposed smart emotional lighting control system to reduce the emotional lighting device, internal heat and the power consumption was configured to the android platform mobile device and zigbee module, emotional lighting device, lighting control module, power supply, and general-purpose transistor. The mobile device was to transmit the real-time control information to the emotional lighting device when connected to the system, and it was designed to control the emotion lighting device based on the control messages and status monitoring. In this paper, the efficiency verification results of the proposed smart emotional lighting control system showed that it was possible to control by emotion lighting control and the color temperature variable. The heating value and the power consumption could be reduced by21% and up to 48%, because of the controlled lighting using emotion language.

The purpose of this article is to examine the research trends of 'bibliography' in Korea. By utilizing citation analysis methods, total 1,321 cited references of the 51 articles published by ${\ulcorner}Journal of the Institute of Bibliography{$\lrcorner}$ in 2000 and 2001 are analysed. This analysis is focused on an article's subjects and authors'occupations, the numbers and journal categories of its cited references. Also, this study observes the nationalities and languages of cited references and various items related to authors of cited references. The most of findings of this study are similar to the previous studies. However, it could find that there are minor differences from the existing literatures, in respect to subject areas, the number of cited references and the forms of cited references. In conclusion, this study recommends that bibliographers's collaborative works with related fields such as history and library and information science need to be strengthened, and that qualitative apaches as well as citation analysis methods might be beneficial for further expansion of academic scope of 'bibliography'.

For a risk analysis in a chemical process, it is important to reflect correctly the characteristic properties of the target process. In this study, computational fluid dynamics (CFD) was adopted for the advanced risk analysis in a residual hydro desulfurization (RHDS) process by considering operation condition, layout of instruments and facilities, atmospheric condition, and wind direction. Release and explosion simulations for the RHDS by using FEA (Finite Element Analysis) and CFD showed the applicability of 3D scanning methods for estimation of release hole size and release amount.

The purpose of this study is to examine mediating effects of social adaptation on the relationship between employment status and mental health in a sample of marriage immigrant women. Social adaptation was assessed with Korean proficiency and the length of residence in Korea. Participants comprised of a total of 247 marriage immigrant women who reside in Seoul, Incheon, Gyeonggi-Do. The data were analyzed by the PASW Statistics 18.0 and the AMOS 18.0 software. The results showed that the social adaptation was a full mediator of the relationship between employment status and mental health. It is plausible to state that employment status may enhance social adaptation, which in turn improve mental health among marriage immigrant women. The implication of our findings is that as employment and social adaptation are important elements of mental health among the marriage immigrate women, education and social support system regarding these antecedent factors should be implemented.

In this study, it was investigated if there were some differences on the preference of researchers to grey literature among seven different subjects in the field of science and technology using citation analysis. The result shows that there were some differences among researchers, depending on the subject area. It also appears that the preference of grey literature of researchers is dissimilar in journals in English and journals in Korean, regardless of the subject area. Finally, partial correlation coefficient among nine different types of material was counted with the control of languages used and subject areas included. Among nine types of cited documents, the value of partial correlation coefficient between proceedings and miscellaneous is larger than that of any other coupled comparison This means that researchers who cite articles from proceedings tend to include information from miscellaneous at the same time.

In this paper, we present a reducing power conswnption of a scheduling for module selection under the time constraint. The proposed low power scheduling executes FDS_LP considering low power to exist the FDS scheduling by inputted the behavioral language. The proposed FDS_LP perfonns lower power consumption with dynamic power which is minimized the switching activity, based on force conception In the time step of module selection, an optimal RT(Register Transfer) library is composed by exploration of the parameters such as power, area, and delay. To find optimal parameters of RT library, an optimal module selection algorithm using Branch and Bound algorithm is also proposed. In the comparison and experimental results, The proposed FDS_LP algorithm reduce maximum power saving up to 23.9% comparing to previous FDS algorithm.

In this paper, a novel approach to using Subcircuit of Pspice in designing feedback for DC-DC converter systems is proposed. Proposed new approach, the feedback design procedures which are based on small signal modeling are programmed as a subcircuit in Pspice. For this purpose, Analog Behavioral Modeling (ABM) is used. By using the subcircuit, the component values of the error compensation amplifier can be easily obtained by means of Pspice DC analysis. The methodology of development is presented in detail and application examples demonstrated the effectiveness of the proposed approach in designing feedbacks for DC-DC converters. The converter with PWM method used continuous current mode and calculated buck converter control signal with average and linear current technique. To decide pole and zero K-method was adapted and this kind of design procedure took stable function.
