Purpose: The purpose of this study was to identify the effects of an exercise program on muscle strength, Activities of Daily Living (ADL), health perception, and depression among post-stroke elders. Methods: Nonequivalent control group design with pretest and posttest was used. A total of 23 post-stroke elders who met inclusion criteria were recruited. Muscle strength in upper and lower extremities, ADL, health perception, and self-rated symptoms of depression were measured. The exercise program consisted of deep breathing, range of motion, and muscle strengthening exercises using Thera-band, 30~40 min/day, three days a week, for 12 weeks. Results: Muscle strength of right shoulder (U=11.50, p=.001), right leg (U=13.50, p=.002), and health perception (U=24.00, p=.010) in the experimental group was significantly higher compared to the control group at 12 weeks of post-intervention. Depression scores were significantly lower in the experimental group compared to the control group at 6 weeks (U=28.00, p=.021), at 12 weeks (U=22.00, p=.006) of an exercise program. Conclusion: By applying this program, post-stroke elders showed increases in muscle strength and a decrease in depression as well as improvement of health perception. Further study is needed to verify the effects of the exercise program on cardiovascular physiologic variables through long-term follow-up.

Place assimilation in Korean has been argued to reflect the consonantal strength hierarchy in which velar is stronger than labial which is in turn stronger than coronal. The strength relationship has been manifested in two ways in literature. One is through phonological representation as shown in Iverson and Lee (1994). The other is through perceptual salience ranking as suggested by Jun (1995). The goal of this study is to examine the perceptual salience of placed consonants through an identification experiment. The experiment conducted in this study reveals four facts. First, place identification of a prevocalic consonant is higher than that of a postvocalic one. Second, place identification of a stop in coda is more confusable than that of a nasal counterpart in Korean contrary to other previous studies. Third, velar is most confusable in place identification in contrast to Jun (1995) and Hume et al. (1999). Finally, place perception of consonants can vary depending on adjacent vocalic context. These results suggest that perceptual salience is one of the possibly several factors affecting a phonological process.

The purpose of this study was to identify the determinants of traditional food perception, by taking the generation effect into account. This study also analyzed the preference patterns of traditional snacks and the strength as well as direction of improvement for traditional foods. Data were collected from 304 housewives living in the Baeong-Nyeong-Do island. Regression analysis showed that the determinants of traditional food perception varied depending on the generation of housewives. In the 30s age subgroup, income and family type were significantly related with the degree of traditional food perception. In the 40s age subgroup, household income, education, and hometown location were significant, whereas household income, family type, number of years of life spent in the Baeong-Nyeong-Do island, hometown location were the significant factors in the 50s and 60s age subgroup. The results of factor analysis showed that there were three preference patterns of traditional snacks. The results of chi-square analysis proved that foods for strength, and direction of improvement for traditional foods were different among the generation groups. In this article, similarities and differences between determinants of traditional foods, the strength and direction of improvement for traditional foods are discussed, and their implications for nutritionists as well as food marketers are provided.

One of main issues in watermarking is to resolve the strength of watermark for solving the problem of trade-off between fidelity and robustness of watermarking. In the previous research, the strength of watermark has been resolved fixed value generally without considering local image characteristics such as image brightness, contrast, and edge. This paper proposes a new model to predict the strength of watermark considering local image characteristics such as image brightness, contrast, and edge for digital wavelet transform(DWT)-based image watermarking. For the study, psychological experiment was fulfilled to measure the human image perception and regression analysis showed the proposed model was statistically significant at the level of ${\alpha}\;=\;0.01$. Also the model is practically validated on fidelity and robustness of watermarking.

The purpose of this study was to investigate the relationships of ego-resilience, family strength, and school life satisfaction according to their family structure. 303 cases of them were selected from 912 elementary students' data in Busan and analyzed using the independent-samples t-test, Pearson's coefficient of correlation, and multiple regression. The results of the study were as follows: First, it was shown that children of parents family had positive perception on the ego-resilience, family strength, and satisfaction with school life than children of nontraditional family. Second, in children with parents family, family strength is a more powerful predictor of satisfaction with school life than ego-resilience. Finally, in children with nontraditional family, ego-resilience is a more powerful predictor of satisfaction with school life than family strength. The results implicated that ego-resilience and family strength of children influence on their school life satisfaction differently according to their family structure and therefore it needed for family structure-based mediation program to improve children' school life.

본고의 연구는 SNG 서비스의 이용에 있어 사용자간의 약한 유대관계의 힘과 감성적 상호작용이 만족과 구전에 이르는 경로모형을 검증하고, SNS가 지닌 감성적 실명효과가 서비스 확산에 미치는 영향 및 정책적 함의를 확인하고자 하였다, 연구결과 모바일 SNG 사용자의 약한 유대관계의 힘이 사용자간의 감성적 상호작용성과 만족에 영향을 미치는 것으로 확인되었다. 또한 SNS의 감성적 실명효과로 인해 사용자들은 신뢰관계가 형성되어 약한 유대관계임에도 불구하고 감성적인 상호작용을 하는 것으로 판단된다. 그리고 구전에 영향을 미치는 변인은 선행한 유대관계나 상호작용이 아닌 만족인 것으로 나타났다. 선행변인들이 실명SNS 효과가 있지만 궁극적으로 서비스를 구전하게 하는 것은 만족이라는 요소에 의해 좌우된다는 것이다. 따라서 서비스 제공사업자들은 구전으로 전달되는 서비스의 만족을 이끌어 낼 수 있도록 고객 중심의 정책으로 SNG 서비스를 개선시키는 등의 실무적 제언이 가능 할 것으로 기대된다.

The purpose of this study was to examine the effect of the children's school adjustment on family strength, social support and parental efficacy according to their parents perception and to submit basic material to recognize the necessity of strengthening parental capability for enhancing children's adaptation to school. The summary of the results of the study was as below. All of the subjects who recognized family strength, social support and parental efficacy according to their parents perception showed middle score over 3. The parents who recognized family strength and parental efficacy were examined as the factors which influence children's adjustment to school. These showed that children's adjustment to school is better when parents recognized that family strength is higher, and when parents recognized that parental efficacy is higher. But when parents recognized social support, no meaningful influence appeared, so if the parents who are first social supporters of school-aged children understand the importance of children's adjustment to school, which has a high adaptability with high social support, and recognize the difference of the influence of social support on the children's adjustment to school and home, it could be the factor to reduce children's adjustment problems at school.

The interactions between two-dimensional and three-dimensional stimulus configurations on visually induced self-motion perception (vection) were examined. The experiment revealed that there is no 2D-3D interaction, and vection strength is determined solely by the size of the moving background stimulus, which should be a primary factor in inducing vection.
