The purpose of our study is to confirm the trend of the muscle activity of the trunk and lower limb muscles by the attack method and phase during volleyball exercise. To achieve this purpose, spike serve and spike were conducted for 9 male middle school students, and at that time, it was divided into four phase, such as run jump, take off, impact, and follow, and the rectus abdominis, erector spine, and left rectus femoris, left biceps femoris, left anterior tibialis, left gastrocnemius midialis, right rectus femoris, right biceps femoris, right anterior tibialis, right gastrocnemius midialis, were examined. Spike serve and spike were each performed three times, and randomly cross-allocated to extract accurate data. We was no difference in all muscles according to the attack method, and the muscle activity of the rectus abdominis was highest in the impact phase and the muscle activity of the vertebral spine muscle was highest in the close-up phase. In addition, all of the measured left and right lower limb muscles showed the highest muscle activity between the assisted devices. As a result, We found out that regardless of the method of spike serve and spike, the lower limbs in the run-up phase for a high jump, the vertebrae in the take off phase, the preparation phase for hitting the ball strongly, and in the impact phase at the moment of hitting the ball. It can be seen that it exerts the greatest power in the rectus abdominis.

The objective of this study was to determine the perception of monosodium glutamate (MSG) contents in eating out menu and MSG symptom complex. Respondents in the Seoul area were surveyed from Feb. 10 to 20, 2014. The results are summarized as follows. The 51.3% of respondents were male and 48.7% of them were female. As for age, 73.5% of respondents were 20~24 years old. Favorite menu of respondents' eating out were Korean food (57.8%), Western food (17.6%), Fast food (9.5%), Japanese food (6.2%), Chinese food (5.2%). Male respondents favored Korean food (62.4%), Fast food (10.2%) and Western food (9.6%), but female respondents favored Korean food (53.0%), Western food (26.2%) and Fast food (8.7%). The 48.7% of respondents considered Chinese food containing high amount of MSG. A few respondents (18.6%) recognized to usage amount of MSG as consideration factor to select eating out menu. However, most respondents (55.2%) perceived harmful to take excessive amount of MSG contained food. The 37.9% of respondents had experience of MSG symptom complex after eating out. Respondents' self recognized MSG symptom complex were thirstiness (84.5%), drowsiness (55.7%), weakness (34.5%), nausea (30.2%), tightness (20.7%) and headache (14.7%). The 19.9% of respondents like MSG contained food. The reason for disliking MSG contained food were 'bad for health' (66.3%) and 'MSG symptom' (33.2%). The reason for liking MSG contained food were 'good taste (83.6%) and 'habitual eating' (14.8%). The result of this study showed that some sensitive people have unpleasant reaction after eating out. Therefore, it is suggested that natural flavor enhancer may develop to replace the use of MSG.

This study examined the relationship between the eating out behavior of families and a low-salt management by housewives in Jeonju area. Self-administered questionnaires were collected from 420 housewives. Descriptive statistical analyses was completed using SPSS v. 19.0 and Stata 13.0. The frequency of eating out and delivered food of housewives in their 20s was significantly higher than that of the older housewives (p<0.001). The high order frequency delivered foods were chicken menu and Chinese food. The determinants of the eating out menu were children's preference and meal time. The average scores of 'interest on low-salt diet', 'attitude toward a low-salt purchasing', and 'praxis a low-salt diet' were $2.70{\pm}0.95$, $3.06{\pm}1.13$, and $3.26{\pm}0.91$, respectively. The level of a low-salt management housewives in their 20s was higher than that of the older housewives (p<0.001). Regression analysis showed that various factors (e.g. age, number of children, education level, and frequency of the eating out) correlated with the low-salt diet of subjects. For the adequate eating out behavior of families and low-salt management of housewives, information and consumer education to take family-related situations into consideration are necessary.

This study surveyed features of weddings in the main family by selecting 10 families in which the grandnephew and grandnephew's wife dwell in the head house, have a shrine, and hold a memorial service for Bulcheonwi (不遷位). A case survey through in-depth interview was carried out from April 9, to October 8, 2011. It surveyed the contents and the wedding artifacts in Uihon (議婚), Napchae (納采), Nappye (納幣), Daerye (大禮), Hyeongugorye (見舅姑禮), which are the procedures of traditional wedding that have been kept in the wedding ceremony of the main family. As a result, in deciding on marriage, the marriage was formed on the basis of similar Gagyeok (家格) and on ancestor's common scholastic mantle or origin. As for wedding furnishings, wedding presents, and wedding gifts, 9 out of 10 families were indicated to give and take weakly. Also, 6 out of 10 families held a traditional wedding ceremony in the yard of the bride's house. Hyeongugorye (見舅姑禮) was indicated to be held by all of the 10 families. A continuous effort in academic circles and industries is demanded for preserving the living culture of the main family, which proceeds with following the traditional elements even amid a rapidly-changing historical flow as today.

Germinal centers (GCs) are formed in peripheral lymphoid tissues in response to protein antigens. In order to see if immunoglobulin isotype switching takes place in GC B-cells, we isolated GC B-cells (PNA positive cells) from mouse popliteal lymph nodes by a flow cytometer after the staining of lymph node cells with PNA-FITC and anti-B220-PE, and determined the expression of ${\gamma}1$ germline transcript and ${\gamma}1$ mRNA by RT-PCR. ${\gamma}1$ germline transcript and ${\gamma}1$ mRNA were amplified specifically in cDNAs from hybridoma expressing IgG1 or splenocytes stimulated LPS plus IL-4. Germinal center B-cells formed in popliteal lymph nodes of mice immunized with chicken ovalbumin were isolated 7 days after immunization. We sorted GC B-cells five times. Immunoglobulin ${\gamma}1$ germline transcripts were expressed in germinal center B-cells in three out of five sorts whereas two out of five sorts did not express ${\gamma}1$ germline transcripts in GC B-cells. The contents of GC B-cells ranged from 5 to 7% of total lymph node cells in most flow cytometric analyses but those of two sorted cells which did not express ${\gamma}1$ germline transcripts were out of normal range. These results imply that isotype switching of immunoglobulins may take place in GCs.

Recycled tire rubber-filled concrete (RRFC) is employed into the steel-concrete composite structures due to its good ductility and crack resistance. Push-out tests were conducted to investigate the static behavior of steel and rubber-filled concrete composite beam with different rubber mixed concrete and studs. The results of the experimental investigations show that large studs lead a higher ultimate strength but worse ductility in normal concrete. Rubber particles in RRFC were shown to have little effect on shear strength when the compressive strength was equal to that of normal concrete, but can have a better ductility for studs in rubber-filled concrete. This improvement is more obvious for the composite beam with large stud to make good use of the high strength. Besides that the uplift of concrete slabs can be increased and the quantity and width of cracks can be reduced by RRFC efficiently. Based on the test result, a modified empirical equation of ultimate slip was proposed to take not only the compressive strength, but also the ductility of the concrete into consideration.

There has been a considerable number of studies on aggressive behaviors and violences, but it is hard to find one that gives us clear and satisfactory answers with transparent conclusions. Juvenile aggressiveness seems to be caused by unsatisfied desire in the problematic situations and emotional instability. The aim of this study is to find out how emotional instability - especially mathematics anxiety - is correlated with aggressiveness and how aggressiveness affects mathematics proficiency, and thus to help students improve their academic proficiency by finding out appropriate measures to take in case of aggressive behaviors of students. Main tasks of this study are as follows : 1. To find out any correlation between aggressiveness of the experimental students and their mathematics proficiency. 2. Is there any correlation between aggressiveness and mathematics anxiety\ulcorner 3. Is there any correlation between aggressiveness and academic proficiency\ulcorner The conclusion of this study is as follows : 1. There are some negative correlations between the degree of mathematics anxiety and mathematics proficiency. This is mainly because negative emotional state developed from one's uneasiness for fear of failure disturbs one's learning process and thus weakens the will for achieving the task. 2. While aggressiveness doesn't show any significant correlations with academic proficiency, it does have some with mathematics anxiety.
