  • The purpose of this study is to explore high school students' understanding of the distinction between scientific theories and scientific laws. Understanding of the distinction between these two concepts, which belong to the nature of science, has been receiving little attention. We surveyed thirty-two students from a local high school with three-part, open-ended questionnaire. The result revealed that these students shared common misconceptions such as 'scientific theories are unproven, scientific laws are proven and absolute', and 'if a theory is proven with enough evidence, it becomes a law'. Moreover, students tend to regard earth science less sophisticated than physical science, because they recognize a lot of its theories to be unproven in their view. It is indicated further that teaching the difference between scientific theories and laws explicitly could help students possess more appropriate view toward earth science.

  • The purpose of the study was to investigate the change of students' conceptual structures about sedimentary rocks through the field trip. A semantic network analysis method was utilized to assess the change. An open-ended questionnaire was developed to assess high school students' knowledge of sedimentary rock including its definition, classification, formation process, and characteristics. Fifteen high school students participated in the field trip of this study. The text data were analyzed using the semantic network analysis method. Results are as follows. First, high school students' conceptual structures about sedimentary rocks were more expanded after the field trip. Second, students' conceptual structures formed a 'small world network' by combining the sub-clusters. Third, the size of students' conceptual structures was decreased after a few month of field trip. Nonetheless, the connection among the clusters remained the same.

  • The purpose of this study is to determine what factors affect the marital life of multicultural families. In-depth interviews were conducted with 15 immigrated females and their husbands living in Yongsan-Gu, Seoul, Korea, by open-ended questionnaire. The interviews took place on September 11, 2008, and October 11, 2008. The major findings can be summarized as follows: Through the content analysis of the informants' responses, three major factors were found to influence the successful adjustment of the married female immigrants: personal factors, familial support, and social support systems. Among the personal factors, the self-esteem of the married couples is relatively high. However, the factor of the economic living conditions of the multicultural families indicates some difficulty. Finally, considering the level of self-development of the female immigrants' husbands, an older husband was viewed more negatively than a younger one. In terms of familial support, the most important factor affecting the adjustment of a foreign wife is the trust of her husband and her relationship with the husband's family. Accordingly, educational programs are necessary to promote multicultural understanding and the couples' relations. In social support systems, the female immigrants experienced neglect, as far as multicultural prejudice in society. Therefore, in order to revitalize the self-esteem of immigrants, we need to reach out to multicultural families. The center for support of multicultural families provides opportunities to find training, upgrade education for employment, and expand their social network. In addition, it is necessary for the national public relations industry to recognize improvements regarding the adjustment of multicultural families.

  • Objectives: This study adopted a qualitative method to explore the layman's beliefs and experience concerning high blood pressure and its management in order to develop a strategy to increase adherence to proper medical treatment. Methods: Semi-structured interviews that focused on personal experiences with hypertension and its management were conducted with 26 hypertensive patients. The participants were selected according to a BP above 140/90 mmHg (hypertension stage 1), based on the seventh report of the Joint National Committee on prevention, detection, evaluation and treatment of high blood pressure (JNC-VII). The interviews lasted for approximately 30 minutes (range: 20-60 minutes). The resulting questions were formulated into open-ended questions. The interview questionnaire was composed 17 items to examine non-adherence to treatment and 19 items to examine adherence to treatment. Results: Most participants recognized that the direct cause of high blood pressure was unhealthy behavior rather than inheritance. Thus, the hypertensive patient believed they could recover their blood pressure to a normal level through removing the direct cause of hypertension (weight reduction, diet, exercise) instead of taking drugs. The reasons for these statements were that the drugs for controlling hypertension are not natural or they are artificial, and they may have side effects, and drugs are not treatment for the root cause of hypertension. Most of the hypertensive patients chose to manage their behaviors as soon as they knew their blood pressure was high. Therefore, we should not divide the subjects into two groups according to their taking drugs or not, but they should be divided into two groups according to their willingness or not to manage their condition. Conclusions: For developing a strategy for an individual approach to hypertension management, we need to develop a client-centered attitude and strategy. That is, we need to tailor our approach to individual cases to avoid generalizations and stereotyping when developing an adherence increasing strategy.

  • The object of this study is to investigate the views of scientifically gifted children about the purpose of scientists' experiments and school science experiments. The children's views were examined using a open-ended questionnaire survey. And then the responses from the children were analyzed with categorization. The results from the study are as follows: First, the children's views about the purpose of scientists' experiments and school science experiments were classified to 2 top-level, 5 mid-level and 21 sub-level categories. Second, it was found that the children considered internal values of doing experiments are more worthy than the social and personal usefulness of the experiments. Third, the gifted children mentioned most frequently that the purposes of the scientist experiment is 'to get the evidences for their theory and argument which is unusual in the regular children's views. Also the discovery of new phenomena and materials, and the generation of new theories and ideas were mentioned as purposes of the scientist experiments. Fourth, the students frequently stated that school science experiments support effective learning of science subject enhancing subject interests and better explanation/understanding. Fifth, relatively many students thought that the purposes of school science experiments are different with those of scientist experiments. Based on the results from the study, some educational suggestions are discussed.

  • The main purpose of this study is to examine the effects of explicit instructions on the nature of science (NOS) on the understanding of science-gifted students. Participants were engaged in 8 explicit NOS instructions spanning 6 months. Data were collected before and after the instructions from 20 science-gifted students using student worksheets, open-ended questionnaires (Views of Nature Of Science, VNOS), and in-depth interviews. The results of this study showed that explicit instructions were helpful in improving the understanding of the tentativeness in science and socially and culturally embedded aspects of science. However, participants not only still possess naive views on the nature of science about the distinction of law and theory and the empirical aspects of science, but also had conflicting views and misconceptions in some areas. The study has implication for development of science-gifted program that the explicit instructions on NOS and science inquiry should be provided concurrently, given the complementary relationship of the two activities.

  • Objectives: The objective of this study was to develop mobile phone application for image-based dietary assessment and evaluate satisfaction regarding respondent's use of the mobile phone application. Methods: We developed a mobile phone application to assess dietary intakes using 24 hour dietary recall. After initial development, application was reviewed by ten adults and revised based on their comments. We recruited 192 volunteers (92 males, 100 females) to use the mobile phone application and to respond to a satisfaction survey. Participants were instructed to use the mobile phone application with fiducial marker five centimeter in width, length and two centimeter height at each eating occasion during designated 4 days, capturing $45^{\circ}$ angle and $90^{\circ}$ angle images of all food and beverage items before and after consumption. After using the mobile phone application for 4 days, participants were asked to complete an online questionnaire on the satisfaction of the mobile phone app. User satisfaction items composed of 12 questions of application user interface, 8 questions of emotional response, 9 questions of eating behavior in 5 likert scale. Participants were also asked to provide additional open-ended comments on the use of mobile phone application. Statistical analysis was performed by using the SPSS 23.0 (Statistical Package for the Social Science). Results: The average user interface score was $2.82{\pm}1.08$, which was close to the 'normal' response. Responses for emotion and eating behavior also were borderline to the 'normal'. Conclusions: This study found that the mobile phone application using 24-hour recall was acceptable to be used to assess dietary intakes for several days. However, there should be a need for such technology to be user-oriented instead of researcher-oriented. Easy and cost-effective new technology is needed for estimating the amounts of food eaten automatically when the photos are taken.

  • The purpose of this study is to provide direction of medical education by analysing medical school student's perception structure about 'happy doctor'. In particular, this study compared perception structure between two groups of students before clerkship and after clerkship. The subject of this study were 1~4 academic year students in medical school. Students' text about 'happy doctor' were collected by open-ended questionnaire and analyzed by using sematic network analysis. Based on the result of network analysis, perception structure of each groups were confirmed. The network of each groups have 'Professionalism' group including words such as 'patient', 'treatment', 'worthwhile' in common. Three groups, 'Professionalism', 'Quality of life' and 'Self-realization' constituted the before clerkship network. And five groups, 'Professionalism', 'Time with family', 'Balance between work and household', 'Interpersonal relationship', 'Physical and psychological health' constituted the after clerkship network. The results of this study is expected to contribute for developing the basic medical education curriculum for 'happy doctor'.

  • The purpose of this study was to investigate students' satisfaction with, perceived ease of movement of, and perceived fit of high school girls' uniforms according to the uniform design. "P" high school, with a one-piece dress-type uniform, and "H" high school, with a two-piece type uniform, were selected for this study. Sixty-five female students from each school participated in the study. The questionnaire was composed of 21 questions about the school uniforms' purchase behavior, design, fit, ease of movement, and modification and participants' demographic information. Students from both schools were generally satisfied with the uniform design. However, in the open-ended response section, many "P" high school students responded that the fact that the one-piece dress pulled up when sitting or raising the hand made it uncomfortable. On the other hand, "H" high school students responded that the skirt was uncomfortable, because it left the body or underwear exposed when the wind blew due to the many pleats in the skirt. In the assessment of the ease of movement, "P" high school students were more likely to describe the uniform as uncomfortable than "H" high school students. Many students responded that they modified their school uniforms, and the length of the skirt and one-piece dress was the main part that was modified. This study suggests that growing female high school students are unsatisfied with the school uniforms' design and fit. Additionally, the perceived fit and satisfaction levels depend on the uniform design.
