  • The present work focuses on the use of coconut fiber in self compacting concrete. Self-Compacting Concrete (SCC) is a highly flowable, stable concrete which flows readily into place, filling formwork without any consolidation and without undergoing any significant segregation. Use of fibers in SCC bridge the cracks and enhance the performance of concrete by not allowing cracks to propagate. They contribute to an increased energy absorption compared to plain concrete. Coconut fiber has the highest toughness among all natural fibers. It is known that structures in the seismic prone areas are always under the influence of cyclic loading. To justify the importance of strengthening SCC beams with coir fiber, the present work has been undertaken. A comparison is made between cyclic and static loading of coconut fiber reinforced self compacting concrete (FRSCC) members. Using the test data obtained from the experiment, hysteresis loops were drawn and comparison of envelope curve, energy dissipation, stiffness degradation were made and important conclusions were draw to justify the use of coconut fiber in SCC.

  • It is necessary to understand a self-expression and communication in cyberspace using digital photography We have studied the digital camera consumer's self-expression and communication skills and strategy through ethnographic interviews. In this study, we have used ethnographic interviews of 7 informants who had personal web site and are using digital cameras. As a result, It has turned out that informants expressed their self taking pictures of their daily life, friends, and family. Also they imply meaning and feeling in the pictures that had been taken to express their lives. The communication in cyberspace has turned out that informants communicate with other people with digital pictures to show their life. They communicated each other and give information. It means that they made information by themselves to give and share with other people as prosumer. Digital photography to express themselves and communicate in cyberspace enhanced human relationship that had made in cyber space. And it helps to form their self identity. They express their cyber identity with digital photography and it is similar to their self identity that expresses in real life.

  • This article is an attempt to explain, at least in part, the contemporary Korean women's consciousness of Western Dreasses. As time changes, the role of clothing undergoes varisous transitions, while values and ways of life are constantly in change. It is, therefore, proper and appropriate to recognize as among the major aspects of social psychology such phenomenon as interests, understanding of clothing, the choice of a dress, and attitudes toward clothing, etc. The purpose of this study is to discover problems concerning and their clothing and their solutions, by means of a surveying approach. The method of research used is based upon questionares distributed to parents of first-year pupils in elementary schools and to female clerks working in offices, covering the period from August through October, 1976. The number of the questionares distrubuted totalled 600, and 526 were returned to the research to be utilized for analysis. The contents of the survey included such things as values concerning clothing, kinds of clothing and their practical use, the selection of clothing and the method of purchase, fashions, etc. The classification of aquisition are self-made clothing, clothing made to order and ready-made materials. It is composed of 25 items, including affirmative reasons as well as negative ones. The processing of the material returned was made by using the computer, and based upon classifications such as ages, monthly income, occupations; thus diagraming the result in percentages. The conclusion made and the improvements proposed are as follows: 1. The values of clothing were placed on the expression of the wearer's personality (32.7) and on eauty(28. 6%). The lower age group places is stress upon the expression of personality, while the higher age group stresses beauty. About 50% of wearers are contented with their clothing, their clothing, the rest of whom them indicating their dissatisfaction with what they wear. As to designs at the time of selection, about 46% indicated their preference of personal expression, 31.8% on usefulness. In selecting material, practicality is emphasized; in selecting patterns, single color is preferred. In short, personal expression and esthetic values are primary, with consideration of practicality in mind. 2. The classification of clothing according to their uses indicates the highest numbers in normal wear (home wears) and clothings to be worn outside home. As to evening dresses, (party dress) only one or two articles were checked by many, and no such article was clamed to be possessed by most. The highest ratio of wearing was shown in the case of home wear (47.3%) and clothing to be worn outside the home, which is 55.8%. The budget for one article of clothing was greatest in the case of home wear, and clothing worn outside the home. Many used both kinds of articles for the same purpose. It is desirable, therefore, that the kinds of clothing should be varied according to the purpose for which they are worn, and that clothing appropriate for that purpose should be worn. 3. The motivation for purchasing clothing was highly chosen in the item of seasonal change, which was 55.7%; Clothing deliberately made was indicated by 45.2%. In the mothods of purchasing clothing, clothing made to order and ready-made was indicated by 44.4%, which is the highest; Clothing made to order was 25.4%, and self-sewing was 1.1%, which is the lowest. (1) In the case of self-sewing, "I like it but it is very hard," was checked by 43.6%; "It is so difficult that I cannot wear such clothing" was checked by 13.3%. From these, we can conclude that the questionees are willing to make clothing by themselves, but techniques involved in sewing and at her problems involved in the skill are complicated but when those problems are eliminated there is a possibility for practice. The response checked by questionees concerning the self-sewing was, "It's economical", which is a clear indication that many questionees are positive for self-sewing. It is generally believed that ready-made clothing is cheaper, but it is not necessarily so. In consideration of the quality of clothing, self-sewing is a necessity, and it is desirable that it should be encouraged. (3) Problems involved in ready-made clothing, such as designs, skills, size (fitting) should be eliminated. When these problems are scientifically gotten rid of, it is possible that affirmative returns will be expected. Affirmative responses such as "Ready-made clothing is economical," "You can select there on the spot," are good signs that many women expect to wear ready-made clothing. It is in this sense that the prospect for ready-made clothing is brighter when much development for ready-made clothing is on the way. 4. Much concern for fashion are checked in such item of questions as "Fashionable clothing in the show window," "Clothes worn by women." The first item was checked by 50.1 %, and the second was checked by 48.6%. The reason for following fashion is "Because many people wear them," which was indicated by 30.4%. The reason for not following fashion is "It is too expensive," which was checked by 29.6%. The 26.2% of the answers indicated that "Fashionable clothing is devoid of personality," The influences of fashion over the development of fashion over the development of clothing are two-fold: Esthetic and active. It is not to be deniable that people follow fashion more or less. 1978.9>

Method: The data was collected from March 15 through 26, 2004. The subjects in this study were 395 students who attended universities located in N and T city. The data analyzed using with SAS program, and analysis of variance, Pearson correlation analysis, multiple regression. Results: Concerning the connection of demographic variables to the past parent-child relations(caring and overprotection), current parent-child attachment(communication, confidence, alienation) made a Significant difference in economic family standard (p<.05), educational level of their fathers(p<.01), birth of order(p<.05) and whether or not they lived with their parents under the same roof(p<.05), past experience of living with their parents under the same roof(p<.01). The relationship of the past parent-child relations(caring and overprotection), and current parent-child attachment(communication, confidence, alienation) made a significant difference to communication(p<.001), confidence(p<.001), alienation(P<.001). The correlation among the past parent-child relations(caring and overprotection), current parent-child attachment(communication, confidence, alienation) and self-concept, caring had significantly positive correlation(p<.001) with communication(r=0.631), confidence(r=0.669) and self-concept(r=0.520), and had significantly negative correlation(p<.001) with overprotection(r=-0.369), alienation(r=-0.531). The overprotection had Significantly negative correlation(p<.001) with communication(r=-0.303) confidence(r=-0.369) and self-concept(r=-0.292), and that had significantly positive correlation(p<.001) with alienation (r=0.275). Overall, the past parent child relations(caring and overprotection) made a 28.2% prediction of self-concept, and the current parent-child attachment(communication, confidence and a sense or alienation) made a 46.1% prediction or self-concept, and their predictability was all significant. Conclusion: This study suggests that perceived the past parent-child relationship(caring and overprotection) is significant influencing factors on present parent-child attachment(communication, confidence, alienation), self-concept. Therefore, nursing strategy is needed to manage these revealed factors.

  • The purpose of this study is to compare the impulsive purchasing tendency of Korean and U.S. college students. In particular, the study examined the effects of self-regulated learning and self-regulated consumption on college students' impulsive buying tendency. A total of 680 valid samples were obtained from online self-reported surveys in Korea and the United States. Both self-regulated learning and self-regulated consumption (self-control and self-supervision) were higher in US college students than Korean students. Self-regulated learning did not influence impulsive purchasing tendency. However, the impulsive purchasing tendency increased as the level of self-supervision among self-regulated consumption decreased. When purchases were made in stores, impulsive purchasing tendency increased in both South Korea and the US. Therefore, it is necessary to make efforts to decrease the impulsive purchasing tendency by fostering self-regulated consumption capacity of college students through consumer education.

  • In compliance with the Industrial Safely and Health Acts, the owners/users have performed self-inspection at regular intervals to secure safety in the use of hazardous machinery, equipment and facilities However, securing safety, which is the goal of self-inspection, has not been thoroughly understood in most small businesses and factories. The objective of this research is to analyze the importance and effects of self-inspection in preventing accidents in businesses and factories that use hazardous machinery and facilities. The result shows that self-inspection has made a good contribution to the prevention of accidents. Most businesses and factories that responded the survey answered they have improved safety in the use of machinery and facilities through self-inspection, though the ways of self-inspection were not all the same. However, the result also reveals that there are rooms for further improvement in the areas of self-inspection intervals, self-inspection methods and the selection of self-inspection objects. This improvement is necessary to improve the effect of self-inspection and to minimize regulations of the government on business activities.
