The main purpose of this paper is to investigate the factors which affect the alienation of the aged, and to study the relative importance of these factors. This study focused on the following research questions: 1) How do the demographic variables(sex, marital status, family structure, religion, economics, prior occupation, education level) affect the alienation of the aged? 2) How the alienation of the aged is affected by their involvement in social activities? 3) Does the degree of satisfaction with family relationship have a perceivable impact on the alienation of the aged? 4) How does the self-rated senescence affect the alienation of the aged? The research was practiced from the 18th Sept. 1999 to the 30th Sept. 1988, through individual interviews with 300 elderly people, all living in Seoul area. Among them only 285 were used in the analysis. The major findings of the study are as follows; 1) The sex of the respondents makes no difference in the alienation of the age . 2) Marital status is found to be relatively significant in determining the alienation. The degree of alienation of old people with spouse is substantially lower than that of those without spouse. 3) Family structure was found to have no significantly effect on the alienation of the aged. 4) Involvement in religion was found to significantly reduce the alienation of the aged. 5) Econimic factors seems to be critical in defermining the aged. The amount of pocket money avaliable for daily use has direct relationship with alienation. 6) Prior occupation was found to be another significant factor affecting alienation professionals experience far lower alienation than nonprofessionals. 7) The higher is education level, the lower is the alienation of the aged. 8) Active participation in social activities and good relationship with other family members were founded to contribute to lowering the alienation of the aged. Whereas, too much concern over one's senescence appears to hav negative effects on the alienation. The regression analysis shows that the satisfaction with the family relationship has the most important influence upon the alienation of the aged. Following are the factors of self-rated senescence, pocket money in a descending order. All these factors, which explain 42.65% of the total variance of alienation variable are statistically significant(p<.001)

The heat transfer phenomenon in the vicinity of the irradiated region of a focused laser beam of a DMT process greatly affects both the deposition characteristics of powders on a substrate and the properties of the deposited region. The goal of this paper is to investigate the heat transfer characteristics of a single bead deposition of Inconel 718 powders on S45C structural steel using a laser-aided direct metal tooling (DMT) process. The finite element analysis (FEA) model with a Gaussian volumetric heat flux is developed to simulate a three-dimensional transient heat transfer phenomenon. The cross-section of the bead for the FEA is estimated with an equivalent area method using experimental results. Through the comparison of the results of the experiments and those of the analysis, the effective beam radius of the bottom region of the volumetric heat flux and the efficiency of the heat flux model for different powers and travel speeds of the laser are predicted. From the results of the FEA, the influence of the power and the travel speed of the laser on the creation of a steady-state heat transfer region and the formation of the heat-affected zone (HAZ) in the substrate are investigated.

The purpose of this study is to examine the effect of the elderly's stress on depression, and also to verify the mediating effect of the elderly's resilience and the moderating effect of their social activity between stress and depression. To achieve the purpose of this study, questionnaire survey was conducted. Research subjects of this study were 487 elderly people who were 60 years old and over in Gimhae area. Both the elderly participating in senior welfare center or community center and home care elderly people were included in survey. The study results are as follows: First, there were significant influence of the elderly's stress on depression. Second, the mediating effect of the elderly's resilience between stress and depression was verified. Both the direct effect of stress on depression and indirect effect of stress through resilience on depression were verified. Third, the moderating effect of the elderly's social activity between stress and depression was verified. It was found that the harmful effect of the elderly's stress on depression could be alleviated by participation in social activity. Through the study result, the elderly's resilience which is internal resource, is needed to be strengthened to alleviate depression derived from stress. Also, the elderly's active participation in social activity is needed to be encouraged to prevent the harmful effect of the elderly's stress on depression. Therefore, it is recommended that programs enhancing resilience of the elderly should be developed and the elderly should be supported to participate in social activity more actively.

Fashion is changing and evolving everyday with an influence from and over contemporary socio-cultural factors. Cartoons expressing the phenomena of times through exchanges of mutual effects with socio-cultural factors that result from functionality and media characteristics. This study examines how fashion provides a great correlation with society-culture expressed in cartoons. The research segment of this study was conducted with literature and case studies; in addition, the UK cartoon magazine "Punch" was selected for the case study. The research findings of the fashion satire expression in cartoon were divided into 2 cases. The first case is that fashion was used as an instrument to satirize socio-cultural phenomena in cartoons. Various fashion elements (hats, dresses, words on T-shirts) were used for satiric expressions and to express periodic images related to politics, economics, society and culture. It communicated factually or criticized noteworthy phenomenon or age changes through the symbolism of fashion. The second case is that fashion itself is the object of satire in a cartoon. It satirically described the blind following and destruction of stereotype as direct objects. Fashion satire appeared in cartoons regardless of a correlation with age. Each cartoon fashion satire had meaning in both humor and criticism for satirizing the age. This study shows that fashion symbolism for satire of the reality has been used as the instrument of expression and simultaneously expressed as the object of the critique as an image and phenomenon that reflects reality. This study has significance in that it examined expressive modes of fashion satire in cartoons that escape from separating fashion from cartoon as a different area.

Landslides is mainly induced by a heavy rainfall, earthquake ground motion, and some other factors like soil mechanics, morphological-geological factors etc. Since the starting point of the failure seemed to be originated at a construction site in the study, it is meaningful to find out the relationship between the landslide and the construction. For this study, the slope failure factor was examined carefully to see that the original natural slope had vulnerability and that the complex ground had unstability changed by construction. A field survey was conducted on the original ground surface and filled-up ground. A laboratory test was also conducted to determine the geomechanical properties of soil samples. 2D and 3D limit equilibrium analysis with changing groundwater level were conducted at the failure depth using a seismic refraction survey. The result shows that the factor of safety is similar stability under all condition, but unstable under saturated condition.

The purpose of this study is to review and overcome the limits of the existing design wave model applied to such waters as those located inside bays or near islands where the impact of wind influenced waves are more dominant, due to the nature of topographic isolation, than the influence of direct waves coming from the open sea. Although the existing model for an inside bay design wave is excellent for considering wind factors and very adaptable to topographically complicated areas compared to other models, it is difficult to show the wave diffractions and reflections caused by large scale structures or topographic features in the region. The study examined the various methods capable of taking into account wave diffraction, the angle of wave reflection, and changes in water depth. As a result of applying the modified design wave model to the target situation (inside bay or near island areas), it was found that the reliability of the design wave height around marine structures was improved, compared to the existing models. Therefore, it is fair to predict that the new model could provide more accurate design waves in the design of marine structures.

Developed ground cavity due to leakage of decrepit old sewer pipe causes ground surface settlement and brittle fracture of pavement. Recently, for 5 years, frequency of occurrence of ground subsidence phenomenon tends to increase rapidly and/or steadily. It is difficult to investigate ground surface settlement and/or subsidence in urban area because most ground surfaces are covered with asphalt or concrete pavement. In this research, therefore, ground surface settlement, influence zone and settlement of sewer pipe were analyzed using finite element method. Not only reinforced effect of pseudo-plastic backfill that is applied to prevent ground surface settlement or subsidence spot, was compared and analyzed using numerical analysis program, but also direct shear test was carried out to determine strength parameters of pseudo-plastic backfill.

The purpose of this study is to see the effects of school climate on school violence and fears of attending school. The direct relationship between school climates and fears of attending school will be examined, as well as the indirect and mediated effects of school violence in that school climates influence the fears of attending school. A theoretical model of the relationships of school climates, school violence, and fears of attending school will be given. The subjects of the surveys were chosen from 12 junior high schools in the Seoul, Gyeonggi area through convenience sampling. 1,317 surveys were then analyzed. School climates directly affect the fear of going to school through the mediums of peer and teacher violence. The derived results stress the necessity of improving school climates in order to reduce violence from peers and teachers and to reduce fear of attending school.

The purpose of this study is to identify the influence of external-social and cultural factors on the perception of corruption in the public society through the Structural Equation Model(SEM) and to seek ways to reduce corruption in the public society. Currently the level of corruption in public sectors that people think is still large, and it is necessary to continuously reduce corruption in public sectors in order to improve national competitiveness. Since one society is a part of a country in system theory and social network theory, public society needs quantitative research in order to find the causes of corruption and solve them. The model was built and the variables were defined in SEM based on 600 questionnaires. As a result of analysis, corruption in public offices has decreased since the implementation of the solicitation and graft law, and socio-cultural factors have had a direct impact on corruption in public offices. The further research area is to seek detailed ways for transforming the education and awareness of civil society across the country in addition to the efforts of the public officials themselves in order to reduce corruption in public offices.

Face recognition of face images is an active subject in the area of computer pattern recognition, which has a wide range of potential. Automatic extraction of face image of the feature points is an important step during automatic face recognition. Whether correctly extract the facial feature has a direct influence to the face recognition. In this paper, a new method of facial feature extraction based on Discrete Wavelet Transform is proposed. Firstly, get the face image by using PC Camera. Secondly, decompose the face image using discrete wavelet transform. Finally, we use the horizontal direction, vertical direction projection method to extract the features of human face. According to the results of the features of human face, we can achieve face recognition. The result show that this method could extract feature points of human face quickly and accurately. This system not only can detect the face feature points with great accuracy, but also more robust than the tradition method to locate facial feature image.
