It is known that individual factors as cognitive, perception, emotion, and motivation may greatly influence on recovery from neurologic region. This study was to investigate the effects of environmental reinforcement through motivation to perform the tasks voluntarily on motor and cognition function in rats with focal ischemic brain injury. Focal ischemic brain injury was induced in Sprague-Dawley rats (15 rats, $250{\pm}50$ g) through middle cerebral artery occlusion (MCAo). And then, experiment groups were randomly divided into three groups; The control group: MCAo induction ($n_1$=5), the environmental reinforcement (ER) group: the application for ER after MCAo induction ($n_2$=5), the environmental reinforcement through motivation (ERM) group: the application for ERM after MCAo induction ($n_3$=5). The climbing test (CT) and the modified limb placing tests (MLPTs) to measure the motor function and the Morris water maze acquisition test (MWMAT) and the Morris water maze retention test (MWMRT) to measure the cognitive function were performed. For the CT, the ERM group was significantly larger than the ER group. For the MLPTs, the ERM group was significantly decreased compared to other groups. For the MWMAT, the time to find the circular platform in the ERM group significantly decreased compared to other groups. For the MWMRT, the time to dwell on the quadrant circular platform in the ERM group was significantly increased compared to other groups. These results suggested that the ERM could improve the motor and cognitive functions in the rats with focal ischemic brain injury.

This paper proposes a novel Random Scheduling Algorithm based on Subregion Coverage (RSASC), to solve the SET K-cover problem (an NP-complete problem). SET K-cover problem distributes the set of sensors into the maximum number of mutually exclusive subsets (MESSs) in such a way that each of them can be scheduled for lifetime extension of WSN. Sensor coverage divides the target region into different subregions. RSASC first sorts the subregions in the ascending order concerning their sensor coverage. Then, it forms the subregion groups according to their similar sensor coverage. Lastly, RSASC ensures the K-coverage of each subregion from every group by randomly scheduling the sensors. We consider the target-coverage and area-coverage applications of WSN to analyze the usefulness of our proposed RSASC algorithm. The distinct quality of RSASC is that it utilizes less number of deployed sensors (33% less) to form the optimum number of MESSs with the higher computational speed (saves more than 93% of the time) as compared to the existing three algorithms.

Recently many efforts have been made to develop new therapeutic agents against skin pigmentation abnormalities. The aim of this study is to investigate the skin-whitening effect of Gleditsia Sinensis Lam and to develop new drug delivery carrier. Inhibitory effaces of Gleditsia Sinensis Lam extracts on melanin synthesis were studied. Namely, UV-absorbing ability, free radical scavenging activity and tyrosinase inhibitory of Gleditsia Sinensis Lam extracts were investigated As a result, the extracts of Gleditsia Sinensis Lam were found to inhibit the activity of tyrosinase. Moreover they absorbed wavelength in the UV-B and UV-C region, and extracts of Gleditsia Sinensis Lam had free radical scavenging activity. In this study, in order to administer these ingredient effectively, the shape of liposome observed by TEM was spherical and uniform.

The results of analyzing the questionnaires with 119 emergency staffs working in Gwangju and Jeonnam region are as follows. 1. The whole stress score was mean 2.94 and the degree of stress from personal relationship was highest as 3.22. 2. There were significant differences in possession of qualification related to public health and medical treatment (F=3.090, p=.030) in service factors, total career of emergency staffs (F=2.979, p=.023) in working environment factors, age (F=2.835, p=.042) and sex (F=2.375, p=.019) in social position factors, possession of medical qualification (F=3.995, p=.010) and household account burden (F=2.777, p=.045) in personal relationship factors. 3. There were correlations (p=.475) between working environment factors and social position (p<0.01) and correlations (p=.508) between working environment factors and personal relationship factors (p<0.01). There was correlation (p=.415) between social position and personal relationship factors(p<0.01). More concrete research that examines whether current fire station operation system is desirable or not by comparing the degree of stress of the whole 119 emergency staffs in Korea is needed and it is considered that real allowance level should be secured to reduce their stresses and facility and guarantee system to satisfy their demands for welfare are required.

The Yellow Sea is known to be a very productive region in terms of fisheries. However, its trophic status seems to be highly variable, ranging from oligotrophic to eutrophic, based on new production (NP) values. The NP and regenerated production (RP) values estimated from $^{15}N$-labelled nitrate and ammonium uptake in spring (April 1996) and winter (February 1997) during this study ranged from 0.05 to 19.8 mg $N m^{-2} d^{-1}$ and from 0.1 to 22.8 mg $N m^{-2}d^{-1}$, respectively. Our measurements and earlier observations suggested that NP in the Yellow Sea varied over the four orders of magnitude (range 0.05-180.9 mg $N m^{-2} d^{-1}$) temporally and spatially, and that RP (range 0.1-507.5 mg $N m^{-2}d^{-l}$) based on ammonium predominated during most period of the year, except in winter when both productions were low. The significant nitrogen uptake by phytoplankton below the euphotic zone and episodic entrainment of phytoplankton from below the euphotic zone into the euphotic zone, and nitrite excretion and dissolved organic nitrogen release during nitrate uptake might explain the apparent dominance of RP in the Yellow Sea.

This research is looking for the relation between the positive psychology of would-be child teachers and leadership and that's influence. The researchers examined positive psychology and leadership with 330 would-be teachers(13 boys, 317 girls) located in Gwang-Ju and the Jeonnam Region. Questionnaire was used to measure would-be teachers. The collected data analyzed the positive psychology of would-be teachers and leaders, including sub-factors for mean(M), standard deviation(SD) and Pearson product-moment correlation according to subject for inquiry. Then regression analysis through SPSS WIN 17.0 for checking the effects of the would-be child teachers's positive psychology with their leadership skill was used. The result of the research was that the positive psychology of would-be child teachers and leadership of the product-moment correlated in all areas. Especially the most influence on positive psychology is the ability of human relationship among leadership sub-variables, and the relation between positive psychology and leadership are very important for making positive changes in society. This implies that there is a need for more educational sponsorship regarding positive psychology and leadership for would-be child teachers.
