  • Soybean seed consists of two major storage protein, the 7S and 11S globulins. For improving the quality of soybean seed protein, an increase of 11S/7S ratio would be a desirable objective because the 11S globulin contains much more the sulfur-containing amino acids than the 7S globulin. In this study, some soybean varieties were used to investigate the analyzing method for 7S and 11S globulins. 7S and 11S globulins couble be fractionated by their different solubilities in tris buffers. Adjusting the pH and tris concentration were major factors affecting the precipitation of the two globulins. And it was possible to screen the soybean genotypes having aberrant subunit compositions of the two globulins by an sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) of total soybean proteins. The ratio of 11S to 7S globulin ranged from 1.29 to 1.38. This paper also dealed with the contribution of protein components in soybean seeds to the physical properties of soycurd. It indicated that the soycurd from crude 11S was remarkably harder than that from crude 7S, and springiness and cohesiveness were slightly higher in soycurd having higher proportion of 11S. So, it may concluded that proportion of protein components in soybean seed can be important factor which controls the suitability for soycurd or other foods.

  • The year 2010 has been regarded as a year of China's assertive diplomacy. A series of China's behavior--including China's critical reaction to the U.S. for its sales of weapons to Taiwan, the Dalai Lama's visit to President Obama, China's arbitrary designation of 'core interests' over the South China Sea, China's inordinate reactions to the sinking of the Cheonan and Yeonpyeong bombardment, and China's activities in the Senkaku/Diaoyu island areas--has served as the witnesses to China's assertive diplomacy in 2010. The major causes of China's assertive diplomacy can be summed up by three factors: potential power transition from U.S. to China; emerging China's nationalism; and the recession of the Tao Guang Yang Hui as a diplomatic principle. But a majority of Western sinologists claim that China's assertive diplomacy is defensive in terms of its character. China's neighboring states, however, perceive its assertive diplomacy as diplomatic threat. Due to these states' geographical proximity and capability gaps with China, these neighbors experience difficulties in coping with China's behavior. In particular, China's coercive economic diplomacy, in which China tends to manipulate the neighbors' economic dependency on China for its diplomatic leverage, is a case in point for China's assertive diplomacy. China's assertiveness seems to be continued even after the inauguration of Xi Jinping government. Although the Xi government's diplomatic rhetorics in "New Type of Great Power Relationship" and the "Convention for Neighboring States Policy" sound friendly and cooperative, its subsequent behavior, like unilateral announcement of Chinese Air Defense Identification Zone (CADIZ), does not conform with its rhetoric. Overall, China's assertiveness has been consolidated as a fashion of its diplomacy, and it is likely to continue in its relations with neighbors. As a neighboring state, the ROK should approach to it with more balanced attitude. In addition, it needs to find out a new diplomatic leverage to deal with China in accordance with its security environment, in which China plays a growing role.

  • In this paper, our goal is to examine the factors of service quality and user's satisfaction in Software as a Service(SaaS). Based on the theoretical framework like service quality theory we develop and test a theoretical model, propose hypotheses and analyze the effects of SaaS' flexibility and customizability on the service quality and the satisfaction of SaaS' users. For this research, questionnaire survey was conducted with literature study and the PLS(Partial Least Square) was used to analyze the measurement model and hypotheses testing. The PLS analysis results indicate that SaaS' flexibility affects SaaS' service quality and the users' satisfaction and SaaS users' satisfaction is influenced by SaaS' service quality. Furthermore, SaaS' customizability affects SaaS' service quality, however, does not affect the users' satisfaction. Practical implications of these findings and future research implications are also discussed.

  • The purpose of this study was to analyze a causal relations of children's learned helplessness, stress, perception of self-competence and mother's childrearing attitudes. The subjects were 370 of 4th and 6th grade in elementary school and the second grade in junior high school in Busan and their's mothers. The instruments used for this study were learned helplessness scale, stress scale, self-perception profile for children, and childrearing attitude scale. The data was analyzed with pearson's correlation, multiple regression and path analysis. The major findings of this study were as follows : 1. Children's global self-worth, social self, age and mother's controlling childrearing attitudes predicted children's stress. 21% of the variance of children's stress was explained by these variables. 2. Children's stress, global self-worth, academic and social self predicted children's learned helplessness. 54% of the variance of children's learned helplessness was explained by these variables. 3. 1) Global self-worth was the first contribution and had a indirect effect through stress as well as a direct effect on children's learned helplessness. 2) Children's stress and academic self had direct effect on children's learned helplessness. 3) Children's social self had a indirect effect through stress as well as a direct effect on children's learned helplessness. 4) Mother's affectionate childrearing attitudes had indirect effect through academic, and social self and global self-worth on children's learned helplessness. Mother's controlling childrearing attitudes had indirect effect through stress on children's learned helplessness. Children's age had a indirect effect through global self-worth and stress and children's sex had a indirect effect through social self on children's learned helplessness.

  • This study was performed to determine possibility of compensatory growth of juvenile olive flounder fed a commercial feed during the summer season. Five treatments of fish with triplicates were prepared: C, S1, S2, S3 and S4. Fish in the control group (C) was hand-fed with the commercial feed to apparent satiation twice daily for 6 days a week during 6 weeks. Fish in S1, S2, S3, and S4 experienced 1, 2, 3, and 4 weeks of starvation before fed to satiation twice daily for 5, 4, 3, and 2 weeks, respectively. The feeding trial lasted far 6 weeks. Survival of flounder in C, S1 and S2 was significantly (P<0.05) higher than that offish in S4. Weight gain and specific growth rate (SGR) of flounder in C and S1 were significantly (P<0.05) higher than those of fish in S2, S3 or S4. And weight gain and SGR of flounder in S2 and S3 were significantly (P<0.05) higher than those of fish in S4. Feed consumption of flounder tended to increase with weeks of feeding. Feed efficiency ratio and protein efficiency ratio for flounder in C, S1, S2 and S3 were significantly (P<0.05) higher than those for fish in S4. Moisture content of the whole fish in C was lowest, but highest for fish in S4, respectively. Crude protein content of the whole fish in C was highest, but lowest far fish in S4, respectively. Crude lipid content of the whole fish in C, S1 and S2 was significantly (P<0.05) higher than that of fish in S4. In conclusion, full compensatory growth was obtained in juvenile olive flounder fed for 5 weeks after 1-week feed deprivation during the summer season. Compensatory growth of fish was well supported by improvement in feed efficiency ratio and protein efficiency ratio.

  • The purpose of this study were to identify the design elements and the changing flow of advertisement from 1970's to 1990's by using content analysis of men's magazines. Finding were as followed; First through the analysis of men's wear advertisement in magazine it was found that the closer to 1990's the more various men's wear styles and backgrounds were advertized. These were more image oriented than product oriented. Since 1980 the advertisement about the licenced and the imported brands have been increased and the serial advertisement has shown more fre-quently than the 1-page advertisement since 1990's ; Second two piece suit was dominated in men's wear during 1970's and 1980's From 1990's this style was decresed in stead combi suit was increased. In 1970's the X silhouette was infashion and the y and the X silhouette was in fashion and the y and X sillhouette were increased during 1980's . The H silhouette was dominated in 1990's The brighter and the more various colors appeared in 1990's than in 1970's. The brighter and the more various colors appeared in 1990's than in 1970's The solid pattern was the main flow in men's wear however the stripes and the the check patterns were added in 1990's Third single breasted jacket style with two buttons and tailored collar was in fashion during 1970's . The length of the v-zone was shorter than half at this time however it was lengthened in 1980's . Also the the length of the jacket was lengthened. In 1990's the double breasted jacket style and two buttons were increased. The length of the v-zone and jacket were also lengthened.

  • This study was performed for the identification of Streptococcus sp. from cultured flounders (Paralichthys olivaceus) showing streptococcosis in the Jeju island. We isolated 10 strains of Streptococcus iniae from the cultured olive flounders with streptococcosis. Isolated strains were identified in S. iniae since they have formed the expected band through performing PCR assay using specific primers, Sin-1 (5'-CTAGAGTACACATGTACT(AGCT)AAG-3') and Sin-2 (5'-GGATTTTCCACTCCCATTAC-3'). In addition to 16S-23S rRNA intergenic spacers (ISR), operon structure of isolated strains showed that all strains had three 16S-23S rRNA ISR band patterns. The 16S-23S rRNA ISR sequence of isolated strains showed 96% sequence identity with S. iniae (GenBank accession number AF 048773). This paper is the first report that S. iniae is associated with streptococcosis of Olive flounder in Korea.

  • In the history of costume, coat can be traced up to ancient Persia but it was generalized as today's style around 14th an d15th century in Euro[pe. World wars, revolutions and rapid social changes of the last 80 years have produced more changes in the way people dress than any comparable period in history. Thewse changes enabled emergence of more modernized woman's garments and through it, dress and coat ensemble became public's main fashion. In 1920's after world war I, boyish style in woman's garment was in vogue. Woman's coat was also in the same style with length sortened up to the knee level and silhoutte was straighter and semi-fitted than previous period. Length of the coat was longer in late 1930's but shortened again in 1940's. And the most popular silhouette of both 30's and 40's was shape of the hourglass which was commonly called the "X-shape". Also double=breasted coat with fitted waistline, belt and flare skirt was in vogue. In 1950's and 60's, with the variety of lines in woman's garments, silhouette of the coat also appeared in many different forms. Along with the various shapes, color of the coat changed throughout the decades : dark colors in 20's, bright colors in 30's, mixed colors of 20's and 30's in 40's and in 50's, color had changed to archromatic. In fabric, wool was most popular in all periods. However, such gabrics as tweed, cotton, gaberdine, linen were added to give variety. It is very interesting to see collars trimmed with expensive furs were very popular in 20's and 30's but it almost disappeared in 40's and fur trimming reappeared in late 50's. In addtion to silhouette changes in design, details such as buttons, epaulettes, pockets and fur trimming of hemline were emphasizing points of varieties in design. This study has set time limits world war I which was the period coat became major fashion of woman's clothing, to 1960's.

  • The purpose of this study is both to describe and to explain the shapes and the changes of Kwangju women's productive activities from the middle of 1950's to the end of 1990's. Productive activities in this study include wage labors as well as economic activities in informal labor sector and domestic labor. Three factors - economic structure, the family, and women's consciousness - are drawn to explain women's work in Kwangju. The period from the middle of 1950's to the end of 1990's has been divided into 5 stages and the characteristics of women's work at each stage are as follows : Kwangju women during 1950's worked hard and contributed to the family economy not only inside but also outside the family : during the second stage from 1960's to 1970's, they accomplished not only the traditional women's role but also industrial wage worker : the third period of the first half of 1980's was the time for the development of social consciousness : the fourth period from the end of 1980's to the beginning of 1990's was the time when women tried to solve their problems by themselves: during the last period from the middle of 1990's to the end of 1990's. Kwangiu women wanted to establish their identities in the independent area from their families.

  • This study examines the relationship between a mother's psychological well-being and children's problematic behavior(withdrawal, depression anxiety, aggression and emotional instability). In order to expand the study on the relationships, special attention was given to the possible mediator effects of mother's coping style with children's negative emotions. The subjects were 305 mothers with children 4-5 years old residing in the cities of Cheonan and Seongnam. It was found that mother's psychological well-being was significantly related to the level of children's withdrawal, depression anxiety, aggression and emotional instability. The mother's coping style with children's negative emotions were also significantly related to the mother's psychological well-being. In addition the mother's coping style with children's negative emotions was found to be a significant mediator of the relationship between mother's psychological well-being and children's. This was especially so for internal problems behavior as like withdrawal, depression anxiety and emotional instability that were perfectly mediated by the mother's coping style with children's negative emotions. Aggression, external problems behavior was partially mediated by the mother's coping style.
