The purpose of this study is to pursue suggestions for the activation of the elementary science camp through the present status of operation and preference survey; examined 50 elementary science camps conducted since year 2004, and surveyed 590 people of students, parents and teachers around Seoul and Gyeonggi province. This study also explores ways of issues and solutions through interviews with five officials of the elementary science camp. This study drew data from the present status of the elementary science camp, the state of camp participation, student's preference, interviews with camp managers. The following are suggestions for the activation of the elementary science camp based on the results of this study; First, the elementary science camp especially in charge of science-related association or office of education should be enlarged, and other private institute or organization should prepare for specialized programs and expert teachers. Second, insufficient camp spot should be solved and participation fee differentials should be alleviated. Third, the period of the camp and its announcement should be various, so that students have more opportunities. In conclusion, managing elementary science camp needs specialism, and continuing effort, because it is related to many important matters such as theme, period, place, participation expenses, guiding teacher, number of student, program organization, student's preference, and method of notice. Therefore, this study insists steady cooperation, continuing endeavor, and appropriate support system for elementary science camps on a nationwide scale.

The purpose of the study was to analyze and interpret parent-child dyadic discourses in depth with emphases on the ZPD system in a museum, an informal learning setting. Second graders and their parents from Seoul and its environs were voluntarily participated in the study. Data were collected from the museum documents, the photos of exhibits, and the video recordings of dyadic discourses at and between exhibits. The documents and the photos were analyzed to investigate what the topics, medium and goals of the exhibits were. The video recordings were all transcribed and analyzed to understand what and how they talked to each other through the lens of the ZPD system; situation definition, intersubjectivity, and semiotic mediation, The results of the study consisted of two parts. First, it showed that parent-child dyadic discourses were categorized in four: (1) within the actual developmental level; (2) in the zone of proximal development; (3) toward the potential developmental level; and (4) out of developmental level. The most common categories were the dyadic discourses within the actual developmental level and in the zone of proxima I development. Second, the representative cases in each categories were described and interpreted to understand the nature of parent-child dyadic discourses. It can be concluded that we gained some important understandings of an intrinsic attribute of parent-child discourses in a museum, an informal learning setting. Based on the results of the study, it can be suggested that museums make efforts to cultivate the affordance of exhibit environment to promote visitor's learning.

When apples are picked or selected by grader, the rate of wound occurrence on the skin by apple stalk is remarkably high if the apple was bigger than 3 size during the harvest time. Except this case, the other sizes showed very little similarity. The crop of apple per 1 minute was 2.9kg without cutting fruit stalk, whereas only 1.1kg of the apples were obtained due to cutting the fruit stalk. Thereby, the harvesting without cutting fruit stalk is highly effective in terms of productivity rather than cutting the fruit stalk. As far as the wound occurrence rate on apple skin by apple stalk of distance between grader's dish and accumulated board is concerned, the grader which has no distance showed quite low rate of wound occurrence compared with those grader with 3cm or 8cm distance. When the apple was being stored, there was no difference in firmness between the cut stalk apple and the uncut stalked apple, however there was slightly more weight loss in the cut stalk apple than uncut stalk apple.

The purpose of this study was to investigate the effect of alcoholic drinking on the dietary habits among university students. The data was collected from 355 students (male : 188, female : 167) living in Busan. The questionnaire composed of general information, person with the lunch meal time, skipping meal, meal type place overeating, snacking eating out, food intake pattern. For statistics analysis, SPSSWIN 12.0 was used. The results were summarized as follows. First, the rates of alcohol drinking in male and female students were 94.1% and 93.4% respectively and the rate of under 19 years old's drinking were 94.4%. Second, in the appearance of drinking, the difference in dietary habits wasn't shown to be significant. However in term of dinner, few female students sometimes haven't dinner (p<0.01). And female group showed frequently eating out (p<0.05) and overeating more than male group(p<0.001). Third, the alcohol drinking group and non-alcohol drinking group showed significantly similar consumption frequency of cereal, meat products, fruits vegetable, oil sugars. But the intakes of milk and dairy products in male students were significantly higher than in female students (p<0.001). These results indicated that more attention should be taken to university students, having habits of skipping meal, alcohol drinking and low intake for nutrition knowledge or attitude so as to improve their health.

This case study examined mathematics anxiety of a public high school sophomore who was unable to perform well in mathematics but later overcame his fear of mathematics. In this study, he showed high levels of mathematics anxiety in the assessment tools that evaluate mathematical anxiety factors. Cognitive and behavior treatments were carried out to alleviate his anxiety. First, cognitive treatments that were implemented include: understanding his own problems, writing down his thoughts on a record sheet, and changing intermediate and core beliefs. This paper explored cognitive and affective changes and reactions during the treatment process. Second, behavioral treatments that were conducted include: the divided-page method and peer tutoring. The divided-page technique involves the test subject to write down and solve his problems on a note to see what kind of cognitive and affective changes occur during the process. This paper also explored how Su-chul, an overly competitive student, changed and reacted cognitively and affectively through peer tutoring. The results revealed that Su-chul's exam anxiety, as well as other factors, has decreased. Moreover, he regained his self-confidence by solving math problems that he had felt difficult. His competitive attitude also has turned into a cooperative and thoughtful one.

In order to find out whether the traditional mass media in our society are sufficiently functioning as a vehicle of providing scientific information to the public outside the school education, public perception of science articles in mass media and scientific terms used in high frequency in science articles have been examined. To investigate the public perception on science articles, a questionnaire was constructed about the usefulness, importance, access frequency, and understanding of science articles. The questionnaires were conducted in areas with high flow populations such as train stations or subway stations. A total of 425 responses were used for analysis. In order to extract high frequency scientific terms used in science articles, two television companies and two newspapers were designated as target media, and their texts on science articles reported over the last 17 years were collected to investigate the frequency of scientific terms used. Based on the frequency, we conducted the self-report comprehension test for the top 100 scientific terms. The results of this study show that the public in our society has relatively high perception of the importance and usefulness of science articles, however, reading and understanding the articles seems to be somewhat difficult. In addition, the scientific terminology used in science articles has a high degree of comprehension for those of higher education, natural sciences majors, and men. In addition, scientific terms with high understanding degree were characterized according to gender, age, educational background, and field of major.

This study was analyzed that what kind of elements for STEAM, except scientific commonsense, are contained in 2009 revised chemistry textbooks I for high school students. So first, elements of STEAM in textbooks were examined by following three sections; by publishing company, each unit and area of textbook. For reference, new sub-elements of STEAM were set because existing elements of STEAM is incongruent with current textbooks. As a result, most chemistry textbooks included elements of STEAM properly for inter-related learning with the other fields. Every textbook had its unique learning methods for utilizing elements of STEAM and they were unified as one way. Depending on textbooks, learning methods were little bit different from the others. Also, detailed elements of STEAM contained in textbooks were classified just 14 types. And they were even focused on a few elements according to sort of textbook. Thus, it seemed that there was a certain limitation of current education of STEAM in chemistry Field. By the unit, according to the curriculum, contained elements of STEAM were different. Almost all elements of STEAM were located in I section. Consequently, it is difficult to include elements of STEAM if mathematics or history were not existed in curriculum. Lastly, by the area, most of all elements of STEAM were included in reference section. Almost all elements of STEAM were focused on art and culture. Thus, STEAM was used for utilization about chemical knowledge in substance. Otherwise, convergence training for approach method was not enough in chemical knowledge.

The purpose of this study is to analyse the descriptive characteristics of the label texts related to Earth Science at a science museum and a natural history museum in Korea. The data were collected from Korean National Science Museum and Seodaemun Natural History Museum. The analysis framework was modified according to the Systemic Functional Linguistics. As a result, characteristics of the labels are 1) mostly declarative sentences, 2) appropriate amount of scientific information, and 3) mainly 'facts'. Moreover, all of the text genre are 4) 'logical expositions'. Particularly in Korean National Science Museum, the labels present 5) more scientific words among the entire terminologies and 6) more than half subjects omitted or long nominalized. Those results may imply that the labels can lead one-way communication regarding the culture of science rather than two-way. This study presents the descriptive characteristics of the label texts to make educationally meaningful communication possible by building an open structure between visitors' own culture in everyday life and the culture of science.

This study aims to find how storytelling classes using fairy tales related to science museum exhibits have an effect on positive experience about science. For this study, the theoretical background and preceding studies on the relevance of science education and literature were collected and based on the characteristics of assimilation and the educational value of assimilation, naturally connected to the exhibits in relation to their own life, so that individuals could explore science even out-of-school. Four types of activities were developed by linking four fairy tales mentioned in elementary school textbooks to the G science museum exhibits. Seven elementary school teachers verified the validity of the activity materials. Classes through the developed activity materials were conducted four times in a row, one and a half hours at every turn for 10 students. A positive experience about science test was conducted on the students in a study to confirm that this activity has caused significant changes in science academic emotion among sub-domains of positive experience about science. In order to find the factors that affected the science academic emotion, we interviewed the students in the study and their parents. The results of this study show that the use of fairy tales related to science museum exhibits has led to a significant change in science academic emotion by reducing the burden of learning through the exhibition experience at the science museum, which creates scientific curiosity and recognizes them as a playground.

This study attempted to examine how sexually abused women with intellectual disability living in residential care facilities interact with their environment, such as personal life, family and communities, and to identify contextual characteristics and needs of these women. Qualitative case study method was adopted, and data was collected through individual and intake interviews, participant observation and a survey with 11 participants residing in a residential care facility for sexually abused women with intellectual disability. The results showed that participants struggled with stresses and emotional instability affected by traumatic experiences of sexual abuse. Family was a system that sexual abused took place, while the systems of residential facilities protected them from potential dangers and violence. Work and school systems also provided them opportunities of learning and having dreams in the future. However, the community system which participants would live after discharging from the facility, had risk factors vulnerable to sexual violence against participants. In conclusion, this study suggested diverse services and programs, such as professional psychotherapy programs, integrated support programs for victim and their families and provision of professional care facilities.
