The question as to the influence of parental attitude on subsequent personality development of their children is a contentious one. Some researchers indicate that parental attitude is perceived distortedly or exaggeratedly by the cognitive trait of the child. In this connection, people are often perceived erroneously due to biased perceptual trait of the individual and the distention in the perception of other people and parental attitude on rearing can be understood in this context. In this study, it was assumed that the individual difference in the child's preception of parental attitude on rearing is due to perception trait as in the case of person perception. In this context it is attempted to clarify the degree of difference in the perception of the mother's warm rearing attitude between mother and child and difference in the person perception due to the perception trait of the child, also, the relation between the difference in perception of mother and child and the person perception is investigated. The subjects are a set of 444 students of universities in Seoul metropolitan area. Questions for testing perceptual trait of students proposed by Jung-Hoon Choi(1972) are used to test perceptual traits of children and 22 pairs of adjectives modified by the authors among 100 pairs of adjectives of Sung-Youn Lee(1988) are used for person perception. 17 questions about the warm rearing attitude among 32 questions about the test of rearing attitude of parents proposed by Young-Mi Lee(1991) are use to measure the warm rearing attitude of mothers perceived by mother and child. The data is analyzed by t-test, paired t-test, and correlation analysis. The result of this study may be summarized of main issues as followed. First, there exists a difference in the person perception due to perceptual trait of the child. Child of positive perceptual trait is more positive in the person perception than child of negative perceptual trait. Second, there exists a difference between the mother and the child in the perception of warm rearing attitude of the mother and the degree of perception of the mother is greater than child's. Third, there exists a differnce in the degree of perception of warm rearing attitude between mother and child due to the perceptual trait of child. The difference in perception of warm rearing attitude of mother between the mother and child is smaller for a child of positive perceptual trait than a child of negative perceptual trait whose level of perception is less than that of the mother. Forth, a child having positive person perception is more positive in the perception of the warm rearing attitude of a mother than mother and child having negative person perception is more negative in the perception of the warm rearing attitude of a mother than a mother.

As EG(Embedded Generation: photo- voltaic, wind, combined heat and power, fuel cell, small hydro etc.) grows fast in adopting to peak load reducing at the middle or the end of distribution system, there much has been interested in interconnection of EG. This paper discusses the various issue of a embedded generator to power system and shows the simulation of its various situation that could happen(focusing on load-flow by EG) by using a commercial software CYME(PSAF) for load-flow. With a result of above simulation, this paper shows a way of possible solution briefly.

During the last several decades, although there have been lots of efforts to develope the high-frequency bottom reflection loss model, the frequency dependence of bottom loss was not considered in most cases because the sea bottom was assumed to be generally much smoother and lower gradient than the sea surface. However, if the sea bottom is rougher than acoustic wavelength, the scattered field will be increased and the reflected field will be decreased. In this paper, the high-frequency bottom reflection losses were obtained through the measurement of reflected waves from the artificially-made-flat sandy bottom. The experimental data were compared with the values calculated by the forward loss model of Mourad & Jackson. Conseouently, we suggest the frequency dependence of bottom reflection loss. 기존 해저면 반사손실 모델들은 해저면을 해수면에 비해 거칠기와 경사도가 매우 평탄하거나 완만한 경계면으로 가정하므로 주파수에 따른변화를 고려하지 않거나 미약하다고 가정하였다. 그러나 고주파를 사용하는 소오나 시스템의 경우, 음파의 파장에 비해 해저면이 거칠다면 음파는 산란 영향이 증가하게 되므로 상대적으로 반사손실 또한 증가하게 된다. 따라서 본 논문에서는 임의로 모의된 사질 성분의 해저면에서 수십 ㎑ 이상의 고주파들을 사용하여 주파수별 반사손실을 계산하고, 이를 기존의 해저면 반사손실 모델과 비교하였으며, 해저면 반사손실의 주파수 종속성을 제시하고자 한다.

Nowadays we globally recognize the importance of the environmental preservation and the environmental energy. The developed countries have already made efforts to realize the saving of energy and the technology based on environment-friendly viewpoint. 'Roof garden' means the restoration of soil eco-system destroyed by rash urbanization and construction. It can also offer the resting place to people in the city. Now it is considered as the realistic way that can solve the serious problems like heat island, pollution and flood in the city fundamentally. In this research, we found out that the following results were obtained: 1) Roof garden is used by users in various objects. Stage, meeting, event, date etc. 2) Users want to design roof garden that have various space features: open and close space, wide and small space etc. 3) The group composed from one to five or more played roof garden. 4) The roof garden aboved have similar facilities excepted one or two. Vaitalization in roof garden remains as a matter to be discussed further.
