The purpose of this study was to find out the way to activate the Education of Korean Traditional foods and culture from middle school subject, Technology and Home Economics Education. We investigated the middle school students' perception and needs for the Education of Korean Traditional foods and culture in their educational curriculum. This study was carried out by using a self-administered questionnaire and 600 middle school students in Gyeonggi province were participated. Most of subjects took the Education of Korean Traditional foods and culture as a part of Technology and Home Economics Education. They recognized that this lecture is necessary and effective, since it is of great help to their life. However, lecture was descriptively given by teacher and not actively participated by students. Therefore, students requested for more practical methods of teaching and learning. They also desired that the education should comprise what will be helpful in a real life. These results suggested that current teaching and learning methods should be corrected and complemented in such a way as to reflect relevant contents and learners' demands which are useful in a real life, so that the Education of Korean Traditional foods and culture may be conducted through middle school subjects of Technology and Home Economics Education in an effective way at school.

This study investigated what effects multiple intelligence, through which the diverse intelligence abilities of a learner are identified, has on technological problem solving ability according to sex. And it was carried out to present a way to reduce the gap between boys and girls in technological problem solving ability. The subject was 833 middle school students in the third grade (boys: 423, girls: 410) whose schools are located in a megalopolis or more large area. And the instruments developed by Yong-Lyn Moon(2001) and in CRESST(1998) were used. The results of this study are as follows. First, it appeared that there were statistically meaningful differences at six items in multiple intelligence between boys and girls. The six items were bodily-kinesthetic intelligence, logical-mathematical intelligence, naturalistic intelligence, musical intelligence, interpersonal intelligence, and introspective intelligence. Second, in technological problem solving ability, it appeared that boys and girls showed statistically meaningful differences at self-regulation and problem solving strategy. Third, it appeared that logical-mathematical intelligence, linguistic intelligence, introspective intelligence, and natural intelligence had an effect on boys in the way of self-regulation and logic-mathematical intelligence, introspective intelligence, naturalistic intelligence, and linguistic intelligence did on girls. Fourth, it appeared that logical-mathematical intelligence, musical intelligence, and bodily-kinesthetic intelligence had an effect on boys in the way of problem solving ability and linguistic intelligence and musical intelligence had on girls. Fifth, it appeared that logical-mathematical intelligence did an effect on both sexes in drawing up the understanding of contents. On the basis of the results of this study, the area related to multiple intelligence directly or indirectly should be developed in the course of designing the primary and secondary curriculums to reduce the gap between boys and girls in multiple intelligence. With these efforts, the scholastic attainments gap caused by the difference of multiple intelligence will be overcome.

Among current health-related issues, obesity is considered one of the foremost, and the importance of this subject has fostered a national interest in body weight loss. In this study, the differences in recognition of body weight loss according to age and gender are investigated. The subjects of the study were 720 (male: 360 and female: 360) aged between 10-60 years, who had experienced to try body weight loss during 6 months prior to this study. Anthropometrics, general characteristics, personal reasons for body weight loss, comprehension of body weight loss, and a knowledge of diet-related issues were assessed through a questionnaire. The anthropometric measurements showed significant differences in height, body weight (present and desired) and BMI (p < 0.05) by age and gender. The difference between desired body weight and actual body weight was greater for younger subjects or female, regardless of whether they had under- or normal body weight (p < 0.05). Reasons for body weight loss varied; younger subjects and female tended to lose body weight "to enhance their appearances", whereas the older subjects and male desired "to improve their health" (p < 0.05). Subjects had different concepts concerning body weight loss; younger subjects and female considered body weight loss as "maintenance of a slender figure, or becoming more lean". On the other hand, older subjects and male thought body weight loss to be "effects approaching normal body weight" (p < 0.05). From our studies, it can be concluded that attitude on concerning body weight loss varied according to a age and gender. Thus, consideration of this individual differences would be vital in developing contents of a particular nutritional education program for body weight loss.

Objectives : Because elementary school children are sensitive and prevalent to dental caries, oral health care program for the elementary school children (ESOHCP) should be met the first priority for the national oral health care program. This study was performed to proposed the guidelines for executing the efficient ESOHCP through the evaluation of present oral health care and education status based on the attitudes and opinions of health teachers. Methods : Subjects were 181 health teachers those are a part of the total 273 elementary school health teachers in Busan. From April to June 2001, questionnaire survey on the teacher's attitude and opinion, present status of oral health care and education in their own school was done. Data was analyzed by $\chi^2$-test, t-test, ANOVA using SAS (ver 6.21) program. Results : Mean age of the teachers was 40 years (24~58 years) and mean scale of the subject school was 32 classes (5~58 classes). Above 90% of them agreed with the necessity and importance of ESOHCP, but actual level of concerning was lower. They gained the informations about oral health mainly from media (33%), PC net (26%), academic society (25%), and more used internet (p=0.012) in younger generation. Though most of them (96%) had a specified school dentist, only 58% had the experience of periodic oral health examinations in their own school. The major experienced ESOHCP was fluoride brushing and contest to choose the best healthy teeth. Oral health education given by the teachers was not professional but their own. About half (42%) of the teachers had never taken education during last one year. Major education materials were VTR tape (79%), teeth model (64%), CD (55%), booklet (50%), etc., and the teachers' preference was also VTR tape (43%) and CD (41%). When they need education materials, they frequently request to dentist's association (36%), academic society (35%), but rarely to dental clinics or dentists (6%). They prefer that two times (46%) of annual oral health education, with the contents of regular brushing (53%), but lower regular visit to clinics (13%). The interest to oral health care (p=0.016) increased with teacher's age. And, they agreed regular students education in case of higher interest(p=0.044). Intention about join in the model school program was decreased with scale of school (p=0.002). Conclusions : This result showed that the present status of ESOHCP is still insufficient. It considered that the health teachers' interest and role is most important for the maintenance and success of ESOHCP. The professional and efficient education program would be focused on the health teachers to induce drive on ESOHCP.

The effect of processing conditions on the changes in the contents of dietary fiber fractions and its physical properteis of Godulbaegi(Korean lettuce, Ixeris sonchifolia H.) was determined during preparation and fementation for kimchi. Water holding capacity(WHC) and oil adsorption capacity(OAC) were also checked on the subject of freeze dried powder from different stages of the kimchi processing. Neutral detergent fiber(NDF) content in young samples(leaf and root) decreased with prolonged soaking and fermentation period. Every young samples had a higher level in NDF than in ripe samples. Noticeable decrease in acid detergent fiber(ADF) without a change in ripe roots was showed after fermentation($4^{\circ}C$, 60 days). The water holding capacity of freeze dried young plants ranged from 5.78ml/g for roots to 6.31ml/g for leaves. Soaking and fermentation resulted in decreasing WHC and about 50% of WHC(raw leaves) was lowered after kimchi fermentation($4^{\circ}C$, 40 days). OAC of all samples were lower than WHC in same samples significantly and those were also decreased after soaking and fermentations as WHC.

The purpose of this paper is to confirm how traditional legends are changing and existing in modern times, and how they are inheriting and developing legendary values and meanings. The subject of the study is uncanny stories concerning army that is judged to be worthwhile alongside uncanny stories concerning school. The uncanny stories concerning army are urban legends that are active in the internet. It can be defined as 'a narrative story that raises fear with supernatural and strange experiences in the army'. In addition to the internet community sites, humor sites and game sites are actively handed down. Recently, ghost stories have appeared on the site, and uncanny stories concerning army are easily collected from these various sites. The uncanny stories concerning army can be divided into three types: ghost experience type, Bulgogi GP type, mystery radio type. The ghost experience type has the largest number of version, the contents are rich and varied. It does not deviate much from the traditional notion of ghosts. Bulgogi GP type has a frenzied horror from its name. It is related to actual events and raises horror. Mystery radio type is a romantic material used in movies and dramas. However, unlike movies and dramas, uncanny stories concerning army are perceived as fearsome. The uncanny stories concerning army continues to emphasize that the story is actually experienced in the title and content. It has presented concrete evidence. The emphasis on truthfulness is intended to make fear more realistic. This comes from the desire for safety. Uncanny stories concerning army focus on horror. So It tries to reveal the history and truthfulness of the story itself. As a result, the history of reality, the truth of reality, and the realistic ideology are erased. Historical and truthfulness of traditional legends has been varied in the case of uncanny stories concerning army.

With the recent growing importance over safety management the need for advanced and technical approaches for on-site safety inspection methods has increased. Railway construction is subject to its own particular set of temporal and spatial challenges due to its unique facilities and equipment. This study aimed to investigate the field characteristics of railway infrastructure and improve the conventional field safety management methods by identifying the most appropriate features of AR technology. Group interviews and surveys were conducted with field safety experts to derive the major problems and inspection needs. Subsequently, various features of AR, such as BIM model projection, and remote conferencing, were investigated to determine their applicability to address safety issues. As a result, four problems in the current safety management process, such as 'lack of time due to the conventional inspection method and inspection of areas that are difficult to access', and three major inspection types, such as 'observance of work procedures, status of installation, adequate dimensional spacing', were identified to be improved when adopting AR based techniques. Furthermore, AR technology utilizing plans to solve safety inspection problems and effectively manage major inspection types were proposed, and a follow up survey was conducted with the same field safety experts to derive the priority of technology development.

The purpose of this study was to investigate the effects of engineering design-based ocean cleanup classes on STEAM attitudes and creative engineering problem-solving dispositions. Furthermore, during this process, we tried to determine interesting points that students encountered in engineering design-based classes. For this study, a science class with six lessons based on engineering design was developed and reviewed by a professor who majored in engineering design, along with five engineering design experts with a master's degree or higher. The subject of the class was selected as the design and implementation of scientific and engineering measures to reduce marine pollution based on the method implemented in an actual Ocean Clean-up Project. The engineering design process utilized the engineering design model presented by NGSS (2013), and was configured to experience redesign through the optimization process. To verify effectiveness, the STEAM attitude questionnaire developed by Park et al. (2019) and the creative engineering problemsolving propensity test tool developed by Kang and Nam (2016) were used. A pre and post t-test was used for statistical analysis for the effectiveness test. In addition, the contents of interesting points experienced by the learners were transcribed after receiving descriptive responses, and were analyzed and visualized through degree centrality analysis. Results confirmed that engineering design in science classes had a positive effect on both STEAM attitude and creative engineering problem-solving disposition (p< .05). In addition, as a result of unstructured data analysis, science and engineering knowledge, engineering experience, and cooperation and collaboration appeared as factors in which learners were interested in learning, confirming that engineering experience was the main factor.

The present paper summarizes the results of an experimental program on the influence of using waste lathe scraps in the concrete mixture on the shear behavior of RC beams with different amounts of shear reinforcement. Three different volumetric ratios (1, 2 and %3) for the scraps and three different stirrup spacings (160, 200 and 270 mm) were adopted in the tests. The shear span-to-depth ratios of the beams were 2.67 and the stirrup spacing exceeded the maximum spacing limit in the building codes to unfold the contribution of lathe scraps to the shear resistances of shear-deficient beams, subject to shear-dominated failure (shear-tension). The experiments depicted that the lathe scraps have a pronounced contribution to the shear strength and load-deflection behavior of RC beams with widely-spaced stirrups. Namely, with the addition of 1%, 2% and 3% waste lathe scraps, the load-bearing capacity escalated by 9.1%, 21.8% and 32.8%, respectively, compared to the reference beam. On the other hand, the contribution of the lathe scraps to the load capacity decreases with decreasing stirrup spacing, since the closely-spaced stirrups bear the shear stresses and render the contribution of the scraps to shear resistance insignificant. The load capacity, deformation ductility index (DDI) and modulus of toughness (MOT) values of the beams were shown to increase with the volumetric fraction of scraps if the stirrups are spaced at about two times the beam depth. For the specimens with a stirrup spacing of about the beam depth, the scraps were found to have no considerable contribution to the load capacity and the deformation capacity beyond the ultimate load. In other words, for lathe scrap contents of 1-3%, the DDI values increased by 5-23% and the MOT values by 63.5-165% with respect to the reference beam with a stirrup spacing of 270 mm. The influence of the lathe scraps to the DDI and MOT values were rather limited and even sometimes negative for the stirrup spacing values of 160 and 200 mm.

In order to prepare for changes in future society, cross-curricular learning is emphasized, and the need to link cross-curricular learning topics and subjects is increasing. However, there are few studies on how to deal with cross-curricular learning in mathematics education. This study analyzed the contents and methods of cross-curricular learning topics in subject-specific curriculum and mathematics textbooks. As a result of the study, the curriculum can be categorized into four types according to the variety of cross-curricular learning topics applied and the presence or absence of a main cross-curricular learning topic, and the mathematics curriculum belongs to the type where some cross-curricular learning topics are dealt with passively and there is no main topic. On the other hand, the analysis of 10 math textbooks for grades 5 and 6 according to the 2015 revised curriculum showed that, unlike the curriculum, various cross-curricular learning topics were applied in the textbooks, mainly environment and sustainable development education, safety and health education, career education, character education, and economic and financial education. In addition, in mathematics textbooks, cross-curricular learning topics appeared in various types such as materials, questions, explanations, illustrations, and in many cases, they appeared mainly as materials or illustrations. Based on these findings, implications were explored and suggested on how to integrate and apply cross-curricular learning topics in mathematics.
