Computer programming has educational effect on improving high-level thinking abilities. However, students initially have to spend too much effort in learning the basic grammar and the usage model of programming languages, which negatively affects their eagerness in learning. To remedy this problem, we propose to apply the Scratch to a Game Developing Programming Class; Scratch is an easy-to-learn and intuitive Educational Programming Language (EPL) that helps improving the Meta-cognition and Self-efficacy of middle school students. Also we used the Demonstration-Practice instruction model with self-questioning method for activating the Meta-cognition. In summary, a game developing programming class using Scratch was shown to significantly improve the Meta-cognition of middle school students. However it was shown to insignificantly improve the Self-efficacy of girl students group.

Purpose: This study was done to review Taegyo types, the practice of Taegyo, factors of Taegyo, and the effect of Taegyo programs in Korea. Method: This study reviewed the preceding research related to Taegyo through websites, articles, and books. Result: As a result of a review of Taegyo types, the practice of Taegyo, factors of Taegyo, and the effect of Taegyo programs through websites, articles, and books, it was summarized that pregnant women were independent people able to practice Taegyo from pre-pregnancy to childbirth for baby's health. If she practiced encouraging behaviors of Taegyo with her husband's physical, emotional, and economical support, she and her husband would easily transition to parenthood and form strong attachments with their baby. In addition, the rate of mother's postpartum depression was decreased. However, some pregnant women felt a psychological, social, and economical pressure to practice Taegyo. Conclusion: Activating organized and accessible to support systems and community networks, such as community health centers, nurses can help pregnant couples to increase self-care through the performance of Taegyo.

Cinchona-based bifunctional catalysts have been extensively employed in the field of organocatalysis due to the incorporation of both hydrogen-bonding acceptors (quinuclidine) and hydrogen-bonding donors (e.g., alcohol, amide, (thio)urea and squaramide) in the molecule, which can simultaneously activate nucleophiles and electrophiles, respectively. Among them, cinchona-derived (thio)urea and squaramide catalysts have shown remarkable application potential by using their bifurcated hydrogen bonding donors in activating electrophilic carbonyls and imines. However, due to their bifunctional nature, they tend to aggregate via inter- and intramolecular acid-base interactions under certain conditions, which can lead to a decrease in the enantioselectivity of the reaction. To overcome this self-aggregation problem of bifunctional organocatalysts, we have successfully developed a series of sulfonamide-based organocatalysts, which do not aggregate under conventional reaction conditions. Herein, we summarize the recent applications of our cinchona-derived sulfonamide organocatalysts in highly enantioselective methanolytic desymmetrization and decarboxylative aldol reactions. Immobilization of sulfonamide-based catalysts onto solid supports allowed for unprecedented practical applications in the synthesis of valuable bioactive synthons with excellent enantioselectivities.

Recently, it is becoming the big issue internationally where the safety problem of the industrial product including the foodstuffs. The way is able to construct the trust of the consumer that the external specialized agency independently operating confirms what production process of the product keep a standard or a technical regulation. This is conformity assessment. In the many countries, agencies entrusted government authority do conformity assessment. Specially, 'certification' in one form of conformity assessment process is operating a certification system at the government and the non-government body in Korea. Also non-government certification is fixed by trusted system from consumer. He has to prepare a competitive power in liberalization time, so need the countermeasure urgently. This study purpose that develops strategy so as to activating of non-government certification system in gist of the origination called 'self-control.' I present activation strategies using SWOT/AHP analysis.

This study examined the relationships among patient safety competence, critical thinking disposition, problem-solving competence, and self-efficacy of clinical nurses to identify the factors influencing the patient safety competence. A convenience sample of 373 nurses working in 4 general hospitals in a Metropolitan area in Korea was selected. After obtaining IRB approval, data collection was done with a structured self-administered questionnaire from October 14th to November 4th, 2014. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient and multiple regression analysis using the SPSS WIN 21.0 program. The participants showed a moderate level of patient safety competence ($3.75{\pm}0.37$), of critical thinking disposition ($3.43{\pm}0.27$), of problem solving competence ($3.54{\pm}0.30$), and of self-efficacy ($3.58{\pm}0.47$). The patient safety competence of the participants showed a significant correlation with the critical thinking disposition (r=.493, p<.001), problem solving competence (r=.616, p<.001), and self-efficacy (r=.475, p<.001). The significant factors influencing the patient safety competence were problem solving competence (${\beta}=.403$, p<.001), self-efficacy (${\beta}=.156$, p=.005), critical thinking disposition (${\beta}=.130$, p=.018), and having the experience of reporting patient safety accidents (${\beta}=.137$, p=.002). The results suggest that educational programs to enhance the critical thinking disposition, problem-solving competence, and self-efficacy would develop the patient safety competence of clinical nurses. In addition, more effort should be placed into reinforcing the patient safety competence by activating the report of patient safety accidents.

The aim of this study is to analyze the effect and limitation of teacher librarians' self-reported appraisals and suggest it's activation plans about school library based instruction (SLBI). According to results of analyses, the SLBI begin with subject teachers' demand for learning materials and teacher librarians play their educational role in Information search & access and representation & synthesis of information during the instruction. Compared with previous studies, the limitations of SLBI we can see in this study are restricted role of teacher librarians, exclusive attitude and antipathy to classroom opening of subject teachers under the SLBI. The bars of promoting the SLBI are also the difficulty of collaborative working with several same subject teachers and subject classroom system. The ways of activating the SLBI suggested in their self-reported appraisals are building intimacy with subject teachers and participating actively curriculum council, peer-supervision and demonstration classes.

Introduction : In Korea, national attention to the workplace health promotion programs (HPP) for employees began in early 1990s. Governmental supports for the HPP and education programs have given to the employees. The purpose of this study is to find the performance degree of employees' health promoting lifestyle(HPL). Subjects and Methods : For this study, 615 employees who attended governmental educations were selected as research samples. The tool for measuring HPL used in this study was developed for Korean by In-Sook Park in 1995. It is composed of 4-point scaled 60 items and divided into 11 subcategories. The data were collected by self reporting questionnaires from June to December in 1997. Those data were analyzed percentile, mean, standard deviation, ANOVA, t-test with SAS program. Major findings are as follows; 1. The total mean score of the employees' HPL performance was 2.66. The average scores of 'harmonious relationships' category were the highest as 3.11, whereas the one of 'professional health maintenance' were the lowest as 2.02. The remains were 'sanitary life'(2.90), 'emotional support(2.85), 'regular diet'(2.84), 'self achievement'(2.78), 'healthy diet'(2.56), 'rest and sleep'(2.56), 'exercise and activity'(2.54), 'diet control'(2.53), 'self-control'(2.52). 2. The factors affecting HLP were category of industries and sex, age, marital status, education level, major, educational experience of health promotion, among personal characteristics. The employees of service industries, female, older age, married, nurse, educated for health promotion, graduated from junior college performed HLP more than the others. 3. The participation rates of employees for HPP were 12.4%, because of limited time and facilities and equipments. Recommendations; 1. The regulation for performing the health promotion programs in the industries is essential for activating industrial health promoting movement. 2. More governmental supports for educations and services for health promotion programs in the industries are needed. 3. For behavioral changes of the employees, the contents of educations have to consist of exercise and activity, rest and sleep, diet and smoking habits. 4. The evaluating studies for ready made health promotion programs in the industries are expected.

In this experiment, the effects of Asterina pectinifera extracts on the activation of immune cells were studied. An immune cell activating factor was partially purified from starfish, Asterina pectinifera, by means of physiological saline extraction, acetone precipitation and heating inactivation. Starfish extracts increased the proliferation of spleen cells and induced the production of IL-6 and $IFN-{\gamma}$ by spleen cells. Also, it increased the proliferation of purified B cells and production of IgM and IgG in the presence of Asterina pectinifera extracts. Starfish extract self-induced NO synthesis in mouse macrophage cell line (RAW264.7). When cell lines was treated with extracts, the mRNA expression of inducible NO synthetase (iNOS), $TNF-{\alpha}$, IL-6, and GM-CSF were markedly increased in RT-PCR analysis. Therefore starfish extract can self-activate spleen cells, B cells and macrophages. These results might be useful in further studies into a possible immune activating agent from the starfish, Asterina pectinifera, for the development of functional foods and drugs.
