Purpose: This study tries to analyze the differences of memory performance and the metamemory of the elderly women according to degree of depression. And also it attempts to find the correlations among the sub-concepts of metamemory which have close relationships to the memory performance followed by the depression. Methods: The subjects of this study are 60 the elderly women who are older than sixty years in Busan city, Korea. We use the MIA(Dixon, et al., 1988) to measure metamemory and measure the memory performances such as the immeadiate word recall, the delayed word recall, the word recognition task, and face recognition. Results: 1. The average point of deprssed elderly womens' metamemory was significantly lower than non-depressed womens' point(t=10.86 p<.0017). Looking into subconcept of metamemory, depressed elderly womens' strategy, capacity, change, achievement point were significantly lower than non-depressed women. 2. In terms of immediate word recall and delayed word recall performances, depressed elderly women are significantly lower than non-depressed elderly women. 3. The degree of depressed elderly womens' metamemory(strategy, achievement, change, capacity) has significant correlations with immediate word recall performances. Conclusion: Metamemory has close relationship with the memory performance of elderly women. And also depressed elderly's sub-concepts of metamemory which have influences on their memory performance are different from non-depressed elderly's sub-concepts. Therefore, when we try to develop some programs to prevent memory decrease of elderly women, we should take these point into consideration.

In addition to technical skills and competencies, communication competence has been identified to be important to engineering students who will be drivers of innovation in a rapidly changing society. Drawing on the previous studies, this research examines the results of an empirical exploration of engineering students' perception of speaking ability and their communicative competence. To date, there has been most of the research conducted on 'writing' (e.g., its educational process, class designs, ability, etc.) for engineering students. However, relatively little attention has been paid to engineering students' speaking ability perception and their competence diagnosis. This study relies on quantitative data obtained from one survey questionnaire and one test conducted respectively. The sample consists of 386 engineering students as well as 481 non-engineering students for the 1st survey. And to measure communicative competence, 150 engineering students as well as 136 non-engineering students participated in the test. Our findings show that firstly, there were significant differences in perception of speaking ability by majors and gender. Whereas there was no difference in the same survey by grade. Secondly, there was a close and significant relationship between sub-factors of speaking ability. Thirdly, there were significant differences in communicative competence by majors. Whereas there was no difference by gender and grade. Fourthly, there was a close and significant relationship between sub-factors of communicative competence. These findings are expected to provide an explanation for the improvement on engineering students' speaking ability and to encourage the participation in extra-curricular activities and programs in engineering school.

This study aimed to clarify meanings of Palkyung(八景) in different regions which can be considered as the prototype of the region's cultural landscape and also to confirm the change process by pointing out landscape characteristics and finally, to provide a foundation for the regions to establish their own identities, so they could be provided against the changes from developments in other areas. The relationship between the characteristics of landscape values and the components of 32 Palkyung in 4 places those are Gogunsan, Wido, Gunsan and Byunsan under Saemankeum area have been analyzed and evaluated from operational point of view to clarify the structure of the landscape concept. Some important differentiation points would be the sunset of the West Sea, sailing boats and the sceneries related to fishing as they are in the West Sea Islands and the coastal regions; and it clearly reflects the local customs and the characteristics of the landscapes. Each of Gogunsan, Wido and Gunsan Palkyung has 2 distance views with 4km of visible area while Byunsan Palkyung has only 1; and it is considered that because it is mountain area. Most of the Byunsan Palkyung has close range views except for Seohaenakjo and there are around 4 close range views in other areas. There were 4 landscape dominated influence areas each in Gunsan and Byunsan, which means that there are comparatively more close to middle range views. Moreover, each region contains 2 to 3 views of psychological influence but as mentioned, Byunsan has only 1 view of psychological influence. Therefore it is very important and valuable thing to consider the scenic relationship, preservation and reconstruction of Palkyung when planning the project.

A Study of the Emotionality of Child and Mother The purpose of this study is primarily to understand the emotional climate of child and mother, which is a significant factor in child study and the home life. A sample was collected from a total of 1,592 of whom 796 are elementary school children with their mothers. Of these 796 children 440 are fom private schools, 190 from public schools in Seoul. The rest are taken from a farming area, 100 kilometers from Seoul. The data was basically obtained through answers to a questionaire distributed in September 1973. In this study, the cross-sectional method, percentage calculation and chi-square test are adapted from factor analysis. With this limited amount of data special attention now, the following conclusions can be drawn from this analysis although special attention should be given in making any kind of generalization about the entire population. 1) Children's emotionality (a) There is a higher percentage of emotionally well-adjusted children as opposed to maladjusted children.(51%>11%) (b) There is no correlation between children's emotionality and the following factors: grade, sex, residential area, school records, and educational level of their mothers. 2) Mother's Emotionality (a) There are more mothers who consider themselves happy than unhappy.(49%>2%) On the other hand a higher percentage of mothers reported feelings of tension and insecurity as compared to those who had feelings of firm security(65%>5%) (b) There is a high correlationshionship between marital adjustment and marital happiness. In other words, the more adjusted, the happier. A high marital happiness has strong influence on the preference of sex, on children's adjustment to their friends, and their present living condition. (c) There is a close relationship between a high marital adjustment and the social development of a child: being fond of fathers, homelife, and the acquaintance with many friends. In the same way, the positive emotionality of a mother in raising her children and their school records are also important. 3) Emotional relationship between a mother and her chid There is a close bond of love and respect between a mother and her child. Moreover, a high frequence of close and open-minded communication exist between them in a family. It is evident that the emotional climate of the mother has a strong and powerful influence on her child.

The purposes of this study were to investigate the relationships among body image, social self concept, and clothing behaviors of adolescents, and to find out the differences of the relationships among these three variables by adolescents' sex and age variables. The research method was survey and the subjects were 656 male and female adolescents in Daejeon. The questionnaire consisted of 4 measuring instruments; body image, social self concept, clothing behaviors and demographic attribution. The data were analyzed by Cronbach's ${\alpha}$, factor analysis, t-test, and path analysis, using SPSS program. The results were as follows. First, adolescents generally evaluated their bodies as middle level on their physical attractiveness and had positive social self concept. And high school students had more positive body image and social self concept than middle school students. Second, on clothing behaviors, 5 dimensions were emerged: clothing interest, psychological dependency of clothing, clothing ostentation, clothing conformity, and clothing satisfaction. Third, there were close correlations among body image, social self concept, and clothing behaviors; body image and social self concept had close interrelationship each other. However, body image had close relationship with only clothing satisfaction dimension, whereas social self concept had close relationships with all clothing behavior dimensions except clothing conformity. In conclusion, this results showed that body image, social self concept and clothing behaviors have close interrelations, therefore, clothing play an important role to enhance adolescents' body image and social self concept.

This study aimed to investigate the effects of shyness of 3 to 5-year-olds and the teacher-child relationship on peer play behaviors. For this purpose, a survey was conducted targeting 33 teachers working with 277 three to five-year-olds at child care centers located in Chungbuk, Korea. SPSS 19.0 was used to implement exploratory analyses and hierarchical regression analysis. It was found that children with low sociability and thoes with close relationships with teachers indicated the least play disruption. Children whose assertiveness and sociability were low and whose relationships with teachers were close were likely to do the most play interaction. However, regardless of the level of the lack of assertiveness and of the lack of sociability, children with close relationships with teachers had a higher level of play interaction. Children with a higher level of lack of sociability and in conflict relationships with teachers had a higher level of play disconnection. Findings of this study highlight the importance of considering the interplay of children's shyness and teacher-child relationships in the development of peer play behaviors.

It is known that tip clearance flows reduce the pressure rise, flow range and efficiency of the turbomachinery. So, the clear understanding about flow fields in the tip region is needed to efficiently design the turbomachinery. The Navier-Stokes code with the proper treatment of the boundary conditions has been developed to analyze the three-dimensional steady viscous flow fields in the transonic rotating blades and a numerical study has been conducted to investigate the detail flow physics in the tip region of transonic rotor, NASA Rotor 67. The computational results in the tip region of transonic rotors show the leakage vortices, leakage flow from pressure side to suction side and their interaction with a shock. Depen ding on the operating conditions, toad distributions and the position of shock-wave on the blade surface are very different close to the blade tip of the transonic compressor rotor. The load distribution and the shock-wave position close to the blade tip had the close relationship with the starting position of leakage vortex and the direction of leakage flow.

This paper describes a distance measurement system with high accuracy that utilizes a stereo-based camera and a pan-tilt unit for automatically maintaining the positional relationship between a vessel and a target on the side of a facility at a close range. The measurement system offers an advantage in that it can measure the distance to a target while tracking it. In order to improve the ability to control the position of a vessel between it and a target while maintaining the distance especially at a close range, the accuracy of the measurement system has to be improved. The accuracy of the distance measured by our system is increased with revisions of the conclusively generated data of distance measurement. We verified the accuracy of our system from an experiment, which generated results that had an accuracy of 30 mm for distances in the range between 2-8 m.

Hearing impairment children possess poor underlying perceptual knowledge of the sound system and show delayed development of segmental organization of that system. The purpose of this study was to investigate the relationship between phonological awareness ability and word identification ability in hearing impaired children. 14 children with moderately severe hearing loss participated in this study. All tasks were individually administered. Phonological awareness tests consisted of syllable blending, syllable segmentation, syllable deletion, body-coda discrimination, phoneme blending, phoneme segmentation and phoneme deletion. Close-set Monosyllabic Words(12 items) and lists 1 and 2 of open-set Monosyllabic Words in EARS-K were examined for word identification. Results of this study were as follows: First, from the phonological awareness task, the close-set word identification showed a high positive correlation with the coda discrimination, phoneme blending and phoneme deletion. The open-set word identification showed a high positive correlation with phoneme blending, phoneme deletion and phoneme segmentation. Second, from the level of phonological awareness, the close-set word identification showed a high positive correlation with the level of body-coda awareness and phoneme awareness while the open-set word identification showed a high positive correlation only with the level of phoneme awareness.
