Objective : This study is conducted to find the influence on upper extremity function, cognitive function and activities of daily living when stroke patients receive task-oriented training in group or individually. Methods : Twenty-six inpatients are assigned to two groups(task training group and individual training group) randomly, who receive rehabilitation therapy after stroke diagnosis for 5 months(june to november, 2012) in a hospital. Both groups receive a task-oriented training for 30 minutes a day for 3 weeks. FMA were used to measure upper extremity function, K-MMSE were used to measure cognition, and MBI for ADL. Results : Before training. two groups were not different significantly in upper extremity function and cognitive function. But in activities of daily living, bathing self(p<.001), feeding, personal hygiene and total score(p<.05) are higher in group training group. After training, upper extremity function is higher in individual training group(p<.001). In both training group, upper extremity function, feeding, personal hygiene, bathing self, dressing, toilet, chair/bed transfers, ambulation and stair climbing, total score are improved significantly(p<.05). In comparing of variation before and after training, upper extremity function(p<.001), feeding and total score of activities of daily living are more improved significantly in individual training group(p<.05). Conclusion : The outcome shows that task-oriented training can improve upper extremity function and activities of daily living in both training group. Especially, the more upper extremity function is improved, the more activities of daily living is improved. In the future, it will be necessary longitudinal study for a long time for more patients.

In the present study was to examine the influence of cold stress conditions on memory function in relation with 5-hydroxytryptamine(serotonin, 5-HT), trptophanhydroxylase(TPH) expression and cell proliferation in the hippocampus. For this study, male Sprague-Dawley rats weighing $250{\pm}10g$ (7 weeks in age) were used. The rats were randomly divided into three groups(n = 10 in each group): the $22^{\circ}C$-control group, the $4^{\circ}C$-3 days group, the $4^{\circ}C$-5 weeks group. The environmental temperature at $22^{\circ}C$ set as the normal conditions, $4^{\circ}C$ was as the cold stress conditions. The present results showed that cold stress conditions shorten latency, representing cold stress disturbed memory function. 5-HT and TPH expressions in the dorsal raphe were increased cold stress. Neurogenesis in the dentate gyrus was increased under cold conditions. The present study revealed that cold stress exerted deteriorative memory function. However, through increasing of 5-HT, TPH and BrdU expression under cold stress conditions did not show memory enhancing effect.

Many former researchers demonstrated that algorithm learning has a positive outcome on students' problem-solving abilities. One of the methods for algorithm learning, the 'programming learning' method is highly effective. However, there are numerous constraints in schools for programming learning. This study attempts to overcome these issues. Squeak Etoys, one of the educational visual programming languages for easy and interesting learning, has been selected as a learning tool. We developed the algorithm-learning curriculum for middle school students. They were divided into a control group and an experimental group. The students learned on the basis of equal curriculum but, they used other learning tools through over a total 6 sessions. The result showed that Squeak Etoys based Algorithm learning has a positive effect on improving middle school learners' problem solving abilities, self-efficacies and logical thinking abilities. Although the students' logical thinking abilities in the experimental group are improved a lot more than the students' abilities in control group, the students' logical think abilities in the both groups are improved. Therefore, algorithm education in secondary schools are necessary. In conclusion, Squeak Etoys based Algorithm learning has a positive effect on problem solving ability and self efficacy. The developed curriculum can be applicable as a basis for study on algorithm learning and educational programming language.

Some bacterial metabolites of Xenorhabdus nematophila (Xn) inhibit phospholipase $A_2$ ($PLA_2$) activity to shutdown eicosanoid biosynthesis in target insects. However, little has been known about the target insect $PLA_2$ of these bacterial metabolites. Eight bacterial metabolites identified in Xn culture broth exhibited significant insecticidal activities against larvae of both lepidopteran species of Plutella xylostella and Spodoptera exigua. Moreover, these bacterial metabolites significantly enhanced insecticidal activities of Bacillus thuringiensis (Bt). To determine target $PLA_2$, we cloned and over-expressed cellular $PLA_2$ ($SecPLA_2$) of S. exigua. Purified $SecPLA_2$ catalyzed phospholipids derived from the fat body and released several polyunsaturated fatty acids. Most Xn metabolites significantly inhibited $SecPLA_2$ activity, but were different in their inhibitory activities. There was a positive correlation between the inhibition of $SecPLA_2$ and the enhancement of Bt insecticidal activity. These results indicate that $SecPLA_2$ is a molecular target inhibited by Xn metabolite.

Purpose: We examined the effects of cognitive flexibility, resilience, and professional quality of life on the job embeddedness of nurses. Methods: The participants were 120 nurses in three general hospitals. Data collection was conducted using self-report questionnaires from May 17 to June 2, 2022. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Pearson correlation coefficients, and multiple regression analysis. Results: There were significant differences in job embeddedness by experience of turnover (t=-3.15, p=.002). The factors influencing the job embeddedness of the nurses were compassion satisfaction (β=.44, p<.001), resilience (β=.24, p=.035), experience of turnover (β=.23, p=.002), and cognitive flexibility (β=.21, p=.027). It was found that 39% could explain job embeddedness. Conclusion: It is necessary for nurses' support programs to be related to the experience of turnover to enhance job embeddedness. The results indicate a need to develop a program for cultivating compassion satisfaction, resilience, and cognitive flexibility to improve job embeddedness.

Objectives : Based on the fact that cognitive functions decline known as comorbid symptoms of depression can precede depression, this study seeks to observe the effects of depressive symptoms and anxiety symptoms on cognitive function in healthy subjects. Methods : To recruit 50 general populations to evaluate cognitive and clinical symptoms and to find out the effects of clinical symptoms on cognitive functions, Pearson correlation and multivariate regression were conducted. Correlation analysis of subdomain cognitive function was conducted for reliability analysis. Results : Trail making test-B that evaluates the execution function correlates with depressive symptoms (r=0.300, p=0.03) and age (r=0.323, p=0.02). Depressive symptoms (β=0.304, p=0.03) and age (β=0.335, p=0.01) were significantly related to Trail making test -B (Adjusted R²=0.148). Subjective cognitive tests correlates with anxiety symptoms (r=0.434, p=0.002). In the correlation between cognitive functional items, Subjective cognitive tests was found to be correlated with other test except Spotter. Conclusions : In this study, depressive symptoms contribute independently to executive functions in addition to demographic characteristics such as age and duration of education. Given that cognitive decline is a common long-term clinical outcome in depression, we expect active early intervention and evaluation of cognitive function to be helpful.
