The purpose of this study is to obtain basic data for constructing a modeling practice program integrated with meta-modeling knowledge by analyzing the cognition level for each meta-modeling knowledge components through modeling practice in the context of the chemistry discipline content. A chemistry teacher conducted inquiry-based modeling practice including anomalous phenomena for 16 students in the second year of a science gifted school, and in order to analyze the cognition level for each of the three meta-modeling knowledge components such as model variability, model multiplicity, and modeling process, the inquiry notes recorded by the students and observation note recorded by the researcher were used for analysis. The recognition level was classified from 0 to 3 levels. As a result of the analysis, it was found that the cognition level of the modeling process was the highest and the cognition level of the multiplicity of the model was the lowest. The cause of the low recognitive level of model variability is closely related to students' perception of conceptual models as objective facts. The cause of the low cognitive level of model multiplicity has to do with the belief that there can only be one correct model for a given phenomenon. Students elaborated conceptual models using symbolic models such as chemical symbols, but lacked recognition of the importance of data interpretation affecting the entire modeling process. It is necessary to introduce preliminary activities that can explicitly guide the nature of the model, and guide the importance of data interpretation through specific examples. Training to consider and verify the acceptability of the proposed model from a different point of view than mine should be done through a modeling practice program.

Due to the recent increase in information encountered on social media, algorithm-based recommendation formats selectively provide information based on user information, which often causes a filter bubble effect by an Echo Chamber. Eco-chamber refers to a phenomenon in which beliefs are amplified or strengthened by communication only in an enclosed system, and filter bubbles refer to a phenomenon in which information providers provide customized information according to users' interests, and users encounter only filtered information. The purpose of this study is to propose a method of efficiently selecting information as a way to improve the filter bubble phenomenon by such an echo chamber. The research progress method analyzed recommended algorithms used on YouTube, Facebook and Amazon. In this study, humanities solutions such as training critical thinking skills of social media users and strengthening objective ethical standards according to self-preservation laws, and technical solutions of model-based cooperative filtering or cross-recommendation methods were presented. As a result, recommended algorithms should continue to supplement technology and develop new techniques, and humanities should make efforts to overcome cognitive dissonance and prevent users from falling into confirmation bias through critical thinking training and political communication education.

Korea has undergone rapid modernization and globalization process in the last few decades. The purpose of this study is to explore how shifting traditional values are impacting Korean elderlies and their perceptions of aging experience. In order to understand how changing social and cultural practices are affecting older adults, the similarities and differences among Korean elderlies living in three different geographical locations are examined in a multidimensional comparative framework. Life story interviews were conducted with 30 Korean elderlies (10 urban residents in Korea, 10 rural residents in Korea, and 10 residents in the US). Paying attention to within-group variation, this study particularly focused on analyzing the psychological, social, emotional, and spiritual experiences that made lives meaningful and resilient in old age in spite of physical decline. Based on analysis of narrative, the following major areas were identified as having positive or negative influence on aging experiences: physical health, emotional health, family relationship, work, leisure/social activity, and spirituality. Common themes of aging well across all settings included: "life not indebted to their offspring," "physical and mental health," and "dying well." Spirituality played a critical role in cultivating perspectives on life and accepting aging process, which were rooted in specific religious traditions participants identified (e.g., Christianity or Buddhism). Interesting differences in the meaning of work and leisure were also found between elderlies residing in Korea and the US immigrant context. One unique factor continuing to negatively affect Korean elderly in rural community was related to shame of not obtaining higher education. Implications for future research are also addressed.

This study investigated secondary school science teachers' experiences to explore the influencing factors in science teachers efficiency (STE). The participants, thirty three secondary school science teachers who have more than four years of teaching experience, were interviewed about describing each teacher's experience throughout one's years of teaching. The grounded theory introduced by Strauss and Corbin (1998) was used to analyze the data in this study. The results of paradigm analysis revealed that STE is influenced by 125 concepts, 38 sub-categories, and 16 categories. In a paradigm model, the central phenomenon was 'constructing STE', and the causal condition was 'want to be a teacher' as career choice motivation. The contextual conditions that have an affect on the central phenomenon were 'self awareness of the teacher' and 'social awareness of the teacher.' The mediate conditions, which facilitated or restrained the action/interaction strategies, were 'societal tendency', 'school climate', and 'personal context.' The action/interaction strategies to control the phenomenon were 'following the line,' 'identifying effective teaching strategies,' 'taking teacher education programs,' and 'contributing to school improvement.' The consequences were 'teacher's self awareness', 'challenge,' and 'stagnating in teaching.' The overall conclusion drawn from this research is that, the definition of STE is beliefs in science teachers' capabilities to set up objects in some school teaching context and, organize and execute the course of action required to attain these. Additionally, STE has three dimensions of teacher's behaviors: science instructional efficiency, efficiency in engaging students, and efficiency in managing school conditions. This study offers insight into the nature of STE and theoretical framework. These findings may give science teachers and teacher educators the practical knowledge necessary to build effective training programs and interventions that would help increase STE and facilitate effective teaching.

Korean society has significantly changed with the onset of a dramatic economic crisis in 1998. From 2000, however, the Korean economy has recovered and currently Korea is enjoying a similar standard of living and economic growth as the pre-1998 levels. This study is a follow-up analysis, comparing the results examining the success attribution of Korean students and adults in 2001 with the results obtained before the economic crisis in 1997. Using the indigenous psychological approach, this study compares the similarities and differences in Korean students and adults' attribution of their personal success before and after the economic crisis. A total of 988 participants, consisting of 481 primary, junior high, senior high and university students and 507 adults (236 fathers and 271 mothers of the students) completed the questionnaire developed by Kim and Park (1998). The results indicate that students perceived their academic achievement and adults perceived successful family life as their most proud achievement. Successful family life included items such as academic success of children, healthy development of their children, and harmonious family life. The person who provided the most significant support for students were parents and for adults, it was their spouse. For students, the importance of friends' social support increased during the high school years. In terms of type of social support, emotional support was reported to be the most important for both students and adults. As for the reason for their success, majority of students and men reported self-regulation and for women, supportive family environment was reported as being the most important. Comparing 2001 results with the 1997 results, the importance of family increased after the economic crisis. Even with the dramatic economic crisis, however, some of the underlying pattern remain strong (such as importance of academic achievement for students, family life for adults, the importance of social support, especially emotional social support from family members, and believing that self-regulation would lead to success). The similar pattern of results obtain before and after the economic crisis indicate that the above results reflect a fundamental values and belief system deeply imbedded in Korean mentality.

This study placed its objectives in suggesting the basic data for setting up an approach to protect the educational environment, by analyzing the relevance between the misconducts of adolescence and the harmful environment around the school, as an object of study, middle school students and high school students all over the country. Thus, this study carried out the questionnaire survey, by the multi-stage of stratified sampling in 2,114 middle school and high school students from June 29, 2000 through July 29, 2000. And the results of analysis were as follows: 1. In case of the ratio of students using harmful environment, the electronic game room had the highest ratio (78.3％); next, the PC room (75.6％), the singing room (71.6％), and the cartoon room (34.3％). 2. In terms of the experiences of using the harmful environment according to the personal characteristics, high school students used it in a higher ratio, compared with middle school students (p〈0.001); the students, whose father graduated from a high school, comparatively used it much more(p〈0.05). Also, when a school is located near to amusement quarters or shopping centers, students used the harmful environment most highly (p〈0.001). And the differences were found to be statistically significant. 3. In case of the perceived susceptibility factors, the harmful environment was found to be used in lower ratio, by the students who answered “very so” to the question item, The more harmful environment facilities are positioned around school, the more student have the opportunities to use them. (p〈0.001). That is, the findings showed that the higher students' degree of perceived susceptibility factors was the less students used harmful environment facilities. The differences were statistically significant. In terms of the ratio of using harmful environment according to perceived seriousness factors, it was founded out that the students, who answered, “If I use any harmful environment facilities, it will be very harmful to myself.”. had the less opportunities of having used them, compared with the students who did not answer so (p〈0.001). This indicated that the higher the degrees perceived seriousness of students, the less they used harmful environment facilities. And the differences were statistically significant. In the side of the ratio of using harmful environment according to the perceived barriers, it was found out that there were any special large differences. That is, perceived barriers had nothing to do with students' using harmful environment. 4. As the result of having analyzed the factors influencing the behaviors of using harmful environment, the factor to explain the behaviors of using harmful environment was found to be the degree of perceived seriousness, among individual perceiving factors; next, the location of a school - one of personal characteristics, the degree of perceived susceptibility and ages, m sequence. 5. Among students' misconduct experiences, drinking was highest (21.6％), next, smoking (11.9％), drug abuse (4.3％), and sexual relations (1.6％), In sequence. Among other problematic behaviors, excessive waste was highest (14.6％); next, disobedience and lie (10.7％), night wandering (7.8％), and bad dressing and making-up (5.5％), in sequence. 6. In terms of the misconducts according to the behaviors of using harmful environment, compared with the students who did not commit any misconducts, harmful environment facilities were used more highly, by each group of students who experienced drinking (p〈0.00l), smoking (p〈0.001), sexual relations (p〈0.05), excessive waste (p〈0.001), disobedience ＆ lie (p〈0.001), and bad dressing ＆ making-up (p〈0.05). And the differences were statistically significant.

The purpose of the study was to determine factors influencing compliance with anti-tuberculosis therapy. The study subjects were 104 tuberculosis patients who have received the initial treatment in 3 health centers of Kyongju-City, Dalseong-Gun in Teagu and Kumi-City. Data were collected between September and October 1995. The patients were classified into the improved group and the non-improved group according to outcomes of 3 month treatment with short-term therapeutic regimen. To find factors influencing compliance with anti-tuberculosis therapy, multiple logistic regression was made. There was no significant differences between the improved group and the non-improved group in sex, age, education level, occupation, family pattern, and habitual change regarding smoking and drinking. The level of knowledge about anti-tuberculosis therapy in the improved group was significantly higher than the non-improved group(p<0.01). Multiple logistic regression analysis revealed that family support for not forgetting medication (p<0.05) wis a predictor of improvement and knowledge about anti-tuberculosis therapy(p=0.054), regularity of medication(p=0.062), and consultation to family, doctor and nurse(p=0.075) were marginal predictors of improvement. Treatment must be given to every patient confirmed as having tuberculosis and must be given free of charge to the patients. The requirements for adequate chemotherapy are prescribed in the correct dosage and taken regularly by the patient for a sufficient period to prevent relapse of the disease after cure. It is suggested that education to the patients should be reinforced and connectedness between patients and tuberculosis control workers and family should be solidated.

As COVID-19 spreads, people's interest in smart learning that can do non-face-to-face learning is increasing nowadays. In this study, we aim to empirically analyze how users' thoughts on COVID-19 and the information quality and system quality of smart learning systems affect users' acceptance of smart learning and examine the effect of perceived sensitivity and severity of COVID-19 on the satisfaction and use of smart learning through concerns about the risk of transmission. In addition, we examined the influence of information quality composed of content quality and interaction quality and system quality composed of system accessibility and functionality on the use of smart learning through user satisfaction. To verify the validity of the proposed model, we conducted a survey on 334 users with experience in using smart learning, and performed the analysis using Smart PLS 3.0. According to the analysis results, among information quality and system quality, only functionality has a positive (+) effect on the satisfaction of smart learning, and satisfaction has a positive (+) effect on the usage behavior. However, it is found that accessibility among system quality do not affect satisfaction, and concern about the risk of transmission has a negative effect on satisfaction. This study can provide meaningful guidelines to researchers when researching smart learning to support students' learning in a pandemic situation of a new infectious disease, such as COVID-19. It will also be able to provide useful implications for educational institutions and companies related to smart learning.

The purpose of this study was to examine the question of whether there is any difference in dietary habits, climacteric symptoms, and general health characteristics of middle-aged women according to food supplements (FS) use. A total of 745 midlife females participated in a face-to-face interview conducted by qualified interviewers, which guaranteed a higher quality of data collection. Three levels of FS use were defined: None, Single, and Multi for 0, 1, and 2 or more types of FS use, respectively. None, Single, and Multi accounted for 33.56%, 33.29%, and 33.15% of total subjects, respectively. FS users (Single and Multi) exerted more interest in FS and were more likely to believe that FS is helpful for health promotion and amelioration of climacteric symptoms than None (P<0.0001). Self-perceived health status of Multi was lower than that of None, but not different from Single (P<0.05). Factor analysis extracted three factors for dietary habits: regularity, variety and moderation, and four factors for climacteric symptoms: emotional, physical, psycho-somatic, and hot flash. The factor scores for dietary variety as well as emotional, psycho-somatic, and hot flash symptoms were higher for FS user than for None (P<0.01). Single reported more frequent family meals compared to None. Findings of the present study elucidated potential links between the level of FS use, dietary habits, and climacteric symptoms of middle-aged women, suggesting a possible scenario: the greater the climacteric symptoms a woman perceives, the more likely the woman will adopt FS use, the greater the efforts toward dietary improvement, such as dietary variety. Based on that, in this study, more peri-menopausal women belonged to Single and Multi; further investigation on the association between FS use, dietary quality, and climacteric symptoms in conjunction with menopausal status may be needed.

This paper is to examine Okdong Lee Seo's historical view through analyzing Yeokdaega("歷代歌"), Okdong's full-length historical epic. As long as Okdong Lee Seo was a Confucian scholar holding moral cultivation as the highest value, his Yeokdaega is hard to explain separately from the Confucian world view. Okdong's Yeokdaega is a long old-style sino-korean poem consisting of 526 7-syllable verses, yet it considerably differs in structure from other historical epics known so far. Okdong's Yeokdaega consists of two parts: the first narrates Chinese historical facts from the beginning to the fall of Ming dynasty, and the second describes the social irrationality of the time and reveals his strong social criticism. It is very different from an ordinary historical epic piece narrating the orders and disorders and the rise and fall of historical facts. It is thought that Okdong's Yeokdaega was written based on his Confucian historical view. It seems that for Okdong the rise and fall of Chinese historical dynasties did not merely mean historical facts but functioned as a tool explaining the reason for people to persue moral cultivation. Okdong summed up his knowledge of the rise and fall of Chinese historical dynasties, his sharp criticism on social irrationality, and his stimulation about the necessity of moral cultivation, and then created a long 526-verse historical epic Yeokdaega. For the reasons, it is not easy to say that Okdong's Yeokdaega is the result of pure literary activities only for artistry. However, Okdong's Yeokdaega is not inferior to other historical epic pieces written by the time in literary value. Especially, Okdong's Yeokdaega can be said to be more meaningful since it was, over its literary value, not only a tool to strengthen his own study and will but also a educational tool for others around himself.
