The object of this study is to inspect how much influence the play-based assertive training program has on the self-expression and learning attitude of elementary students. To perform this study, I set up two subjects of research. First, does the play-based assertive training program have influence on the self-expression improvement of elementary students? Second, does the play-based assertive training program have influence on the attitude of elementary students? I established 28 students in the third grade of K elementary school in Gongju City as experiment group for this research. In experiment group, 1 peformed play-based assertive training program in the class of discretion and extra-curricula activity twice a week and maintained the program for 6 weeks. By the standard of 12 times of performances, I put pre-test and post-test into operation. The major consequences revealed through above processes are followed: First, as the consequence of analyses of differences between pre-test and post-test about self-expression of experiment group adapted by play-using assertion training program, the level of self-expression was advanced meaningfully. Second, as the consequences of analyses of differences between pre-test and post-test about learning-attitude of experiment group adapted by play-based assertive training program, the level of learning-attitude was advanced meaningfully. Among 8 sub-fields of learning attitude, the field of superiority, accomplishment motives, concentration, self-study show statistically meaningful difference s respectively. The conclusion drawn from above consequences is that the play-based assertive training program is very effective in developing students' self-expression and attitude for learning.

The most research on facility layout problems ignored the actual shapes of activity spaces and the aisles between activities. In many cases, the research also ignored the actual shape of building where the activities are to be arranged. In this paper, We present a block based layout technique that applies a genetic algorithm to search for a very good facility layout with horizontal aisles. From the extensive experiments for two different cases with respect to the shape of activity space, it was found that the proposed method generated better layouts than the ones obtained by applying Tam's algorithm in all test problems. The proposed algorithm showed about 10% improvement of performance on the average. We determined the best combination of the reproduction rule and the genetic operators with their probabilities for each test problem through the experiment.

When applying a SQUID system for diagnosing heart disease, it is informative to obtain the source current distributions from the measured MCG (magnetocardiogram) signals since the bioelectric activity in the heart is generally represented by distributed current sources. In order to estimate the Primary current distribution in a heart, the minimum norm estimate was computed, assuming a source plane below the chest surface. In the simulation, current distributions, which were computed for the test dipoles represented well the essential feature of the test-current configurations. Source current reconstruction was performed for MCG signal of a healthy volunteer, which was recorded using a 40-channel SQUID system in a magnetically shielded room. It was found that the obtained current distribution is consistent with the electrical activity in a heart.

This study investigated the quality characteristics of cookies containing laver powder, which is well known for its various functions and biological activity. This study assessed the quality characteristics of cookies containing various concentrations (0, 2, 4, 6 and 8%) of laver powder(LP). To analyze quality characteristics, pH of dough, moisture content, color, hardness, and sensory properties were measured. Qualities, such as pH, brightness, and redness and yellowness and hardness decreased significantly (p<0.001). The total flavonoid and total polyphenol and ABTS radical scavenging activity were proportionally increased with increasing the level of laver powder added in cookies(p<0.001). The antioxidant activity measured by total flavonoid and total polyphenol activities was significantly higher than control and increased proportionally to the laver powder. The result of sensory test shows that sample group adding 2% of laver powder achieved the highest. Based on the above results, this study suggests that the addition of 2% laver powder may be the best substitution ratio for cookies of the improvement of sensory preference and antioxidant. This study exhibited both the functional and health based benefits of laver when it is added to cookies and confirmed the development feasibility of laver cookies considering consumer satisfaction.

Purpose: We investigated the relationship between patient safety culture and safety care activity, and identified factors for safety care activity of entry-level nurses. Methods: The subjects of the study were 204 entry-level nurses working at five general and advanced hospitals with over 500 beds located in C and D City. The data were analyzed using descriptive analysis, t-test, ANOVA, Pearson's correlation and hierarchical multiple regression with SPSS/WIN 18.0 program. Results: Perception of patient safety culture had significant correlations with safety care activity. Multiple regression analysis showed that demographic variables of quality of nursing on patient safety and health state of entry-level nurses affected safety care activity. In addition, patient safety culture in ward and communication affected safety care activity. These factors explained 38% of variance. Conclusion: Based on the results of the study, patient safety culture promotion strategies to facilitate supportive work environment and effective communication are needed.

Background: The serratus anterior (SA) muscle prevents scapular winging (SW) by stabilizing the medial border of the scapula during arm movement. The upper trapezius (UT) and lower trapezius (LT) muscles may compensate for the weak SA muscle in individuals with SW during shoulder flexion. However, there is no study to examine whether compensation by UT and LT occurs in individuals with SW. Objects: This study compared the muscle activities of UT, LT, and SA as well as the SA/UT activity ratio between individuals with and without SW during shoulder flexion with load. Methods: This study recruited 27 participants with SW (n = 14) and without SW (n = 13). Electromyography data of the SA, UT, and LT muscles and SA/UT activity ratio were recorded and analyzed during shoulder flexion with 25% load of the maximal shoulder flexion force. Independent t-test was used to compare the UT, LT, and SA muscle activities and SA/UT ratio between the groups with and without SW; statistical significance was set at α of 0.05. Results: SA activity was significantly lesser in the group with SW than in the group without SW. However, there were no significant differences in the UT and LT activities and SA/UT activity ratio between the two groups. Conclusion: The SA activity was lesser in the group with SW than in the group without SW with 25% load of the maximal shoulder flexion force, but there was no compensatory muscle activity of the UT and LT observed. Therefore, further studies are warranted to clarify the compensatory strategy of scapular stabilization in individuals with SW during shoulder flexion under other heavy load conditions.
