The purpose of this study is to investigate 1) the types of knowledge students ask for in their reading comprehension of science textbooks using an online annotation system, 2) the accuracy of the knowledge provided by the students to their peers, 3) the frequency of knowledge sharing behaviors, 4) the evaluation of the effect of collaborative reading, and 5) the trust among peers as knowledge sharers. Questions made by 241 students in the second grade of middle school using an online annotation system in two chapters of the science textbook were analyzed using Bloom's revised taxonomy and their answers were grouped according to five accuracy categories. Also, questionnaires for the evaluation of the effectiveness of collaborative reading comprehension and of trust among the students were used. The students asked their peers 'understanding questions' which comprised almost 80% of the total questions they made and were similar with individual metacognitive strategies for reading comprehension. Of the total threads, 71% has scientifically correct threads shared by the students. The frequency of the knowledge sharing behaviors was high but this was affected by the rewards (point system). Students evaluated that collaborative reading comprehension conducted through an online annotation system were helpful in their learning. In addition, the ratio of students trusting their peers who did the knowledge sharing is over 80%. This study shows that when students use an online annotation system, they can fill one another's cognitive gaps in the reading process by sharing knowledge. Also, collaborative reading using an online annotation system has proved that cognitive individualization is possible through sharing knowledge interactively and dynamically, unlike reading hard copies of textbooks which are a one way information transfer.

Objectives: This study identified how personal characteristics, healthy behavior and social capital might influence on physical activity of adults. Methods: This study used data from the health survey of a city of Korea. We surveyed 1,000 adults sampled by stratified sampling methods from 67,889 households. Outcome variable was the stage of physical activity which was broken into 5 categories. Sociodemographic factors, healthy behavior, self-rated health status and social capital were used as control variables. Sociodemographic factors included age, sex, educational status, economic status measured by deprivation score, residential period within survey city. Social capital was measured by Integrated Questionnaire for the Measurement of Social Capital (SC-IQ). This study used chi-square test and ordered logistic regression models to examine the associations between independent variables and physical activity. Variables were added to the regression model in three groups using a hierarchical approach. Results: Physical activity was significantly more likely to become active if they have higher educational status, healthier behavior. Among the six dimensions of SC-IQ, only "groups and networks" that is structural dimensions of social capital and "trust and solidarity" that is cognitive dimensions of social capital were significantly related to physical activity of adults. We found that a person having higher density of membership and having larger size of networks showed the high possibility of active physical activity. A person having high solidarity was significantly associated with physical activity, but general trust was inversely related to physical activity. Output dimensions of social capital did not show significant relationship to physical activity. Conclusion: We found that social capital is useful concept to explain health behaviors like physical activity. However we must consider social, cultural and political context of the study to evaluate the effect of social capital to health status and health determinants and to capture the exact meaning of relationship between them. We suggest further researches to refine the concept of social capital and to explain the relationship of social capital to diverse health determinants.

This study considers the problems and social changes caused by the increase of single-person households in the elderly, and examines SmartHome services for them. We chose trust, security risk, self efficacy, social influence, perceived ease of use, and perceived usefulness as factors that affect attitude. The cognitive level of these factors and the difference betweene gender and education level of these factors were analyzed. The analysis showed that the elderly were fully aware of perceived ease of use and perceived usefulness. In addition, the elderly women are more socially influenced than the elderly men in the use of SmartHome services, and there was a significant difference in self efficacy and social influence by education level. This study will provide a new research perspective for subsequent studies and can be utilized as an important underlying study.

Machine translation (MT) quality assessment is an outstanding problem. In the present situation in which the quality of machine-translated products are far from the user\\`s satisfaction objective evaluation of MT system is a prerequisite to building mutual trust between the users and the vendors stimulating constructive competition among the developers and finally leading to improve the quality of MT systems. Especially there emerges a need for an intensive study on how to evaluate the quality of MT systems from both linguistic and data processing aspects and to secure a steady improvement of the translation quality. With due regard to such points we in this paper present a linguistic evaluation of English-to-Korean machine translation based on a test suite composed of 3.373 sentences that were classified into their linguistic phenomena and complexity levels and report the experimental results made from several commercial MT systems.

This study is done to provide basic data on the effective operation of the new policies by examining the satisfaction level of the elderly with dementia visiting dementia care centers located in 25 autonomous districts of S city. Self-administered questionnaires were distributed to 217 elderly with dementia who visited the above dementia care center from July 1 to September 30, 2019. The satisfaction tool is a chart score scale that displays negative-positive expressions at both ends of a straight line. The result shows that satisfaction level is significantly higher in the group with trust in the visiting institutions than in the group with distrust (t=9.74, p<.001), higher in cognitive impairment group than in dementia group (t=0.13, p=.034), and higher in mild depression group than in more severe depression group (t=2.31, p=.022). Satisfaction ratios analyzed by logistic regression shows significant differences in factors like gender, age, education, and walking pattern. In conclusion, it is important to run health support programs that consider user characteristics to improve the satisfaction of newly introduced dementia care centers.

The objective of this study is to identify the types of relationship quality of department store fashion consumers. This study also aims to look at if consumers form different type of relationship quality with various relation partners. In this study, qualitative research was conducted on 25 female consumers to come to a comprehensive and in-depth understanding of fashion consumers' diverse loyal relationships. Fashion consumer's relationship quality consisted of 'self attachment', 'symbolic', 'trust', 'intimacy', 'compensational bind', and 'habitual alternative'. 6 relationship quality dimensions were distinguished according to each dimension's emotional involvement level and conscious activeness level of consumers. While self attachment was classified as emotional and active relationship quality, compensational bind and habitual alternative were typical relationship quality types of fashion store loyalty such as department store loyalty, thus classified as inertial and cognitive relationship quality type. This study might provide a useful direction to apparel brands and retailers in finding out which relationship quality type is more effective for differentiated marketing strategies.

This study explores influences of the relationship between social capital and residents' perception in a collective aspects, and also explores the differences of influence between two groups in 10 rural communities. This study conducts regression analysis with residents questionnaires, and analyzes the relationship of influence among the latent factors, and differences between the two groups. As a results, associational network and social trust factors of social capital are identified as the most important factor in the quality of life and residents' attitudes. In addition, the differences in socio-cultural factor of quality of life and residents' attitude between two groups are identified by comparison with the relationship between two groups, although the explanatory power of both groups is not high. To achieve a successful rural tourism based on the result of this study, rural tourism should consider the regional and demographic characteristics, such as age, occupations and education and so on. The major contribution of this study is to confirm that the impact of social capital on the residents' perception would be different by regions in comparison with two groups, and it will be able to provide useful implication for the rural tourism development in the future.
