This research aims at supplying the basic data for getting the opportunity to understand and take interest in native local foods, seeking the plans for the succession, development and popularization of such foods. It also presents the efficient development direction of native local foods by researching the attitude to native local foods and their importance among the university students living in Busan and Gyeongnam areas. As the results of conducting a cross analysis on the basis of the characters of sex, age, department, and residence periods of demographic characters to survey university students' attitude to native local foods, 38.5% of the respondents said that they have experience of having been interested in them. And the media were the most influential medium to make them get interested in native local foods, and special restaurants for native local foods were most frequently visited to have them. As for the succession and development of native local foods, public relations was the most important factor for promoting them. For the popularization of native local foods, various cultural events and public relations were most needed. As the results of analyzing the importance of native local foods by the demographic characters, there were statistically significant differences according to sex, age, residence period in Busan and Gyeongnam areas.

The aim of this study is to estimate the prevalence of obesity and factors with it Ulsan secondary school girls. A cross-sectional study involving a sample of 485 students aged 12 to 15 years was obtained form secondary schools. Obesity was determined using body mass index(BMI=wt/Ht$^2$). The findings revealed that the average BMI was 19.3, and 4.5% of girls were either overweight and obese(BMI$\geq$25). Subjects were grouped into three categories based on the BMI, sibling obesity, self-consciousness of obesity, eating patterns such as eating snack after dinner and prejudice in food selection, and food frequency score were significantly associated nth BMI, while nutrition knowledge score was not associated with BMI. The fact that several social, environmental and health factors are associated with obesity means that a multisectorial intervention program must be considered in order to decrease the problem of overweight among secondary girls. Such program should include dietary intervention to modify food habits, nutrition education through mass media, introducing information on prevention and control obesity in school curriculum, and allocating sufficient time in the school schedule for exercise activities.

Sixty isolates of Dendrophoma obscurans isolated from 19 important strawberry growing areas of Korea were tested in vitro for resistance to thiophanate-methyl and iprodione. Naturally-occurring thiophanate-methyl-resistant isolates were about 43 percents of isolates tested, whereas iprodione-resistant isolates were 10 percents. All these resistant isolates except SU 1 and SU 2, which were highly resistant to thiophanate-methyl, showed a week level of resistance. Iprodione-resistant isolates were readily obtained in vitro, when mycelial disk of the fungus was incubated on PDA media containing iprodione at the concentrations of $1{\mu}g/ml\;and\;10{\mu}g/ml$, but no thiophanate-methyl-resistant isolate from the mycelia with or without UV irradiation. All these artificially-obtained iprodione-resistant isolates were showed a high degree of resistance. On the strawberry leaves, thiophanate-methyl and iprodione were no longer effective to all resistant isolates at the recommended concentration, and the protective value to highly resistant isolates was much less than that of weakly resistant isolates. Isolates resistant to thiophanate-methyl were also resistant to benomyl but iprodione-resistant isolates did not show cross-resistance to thiophanate-methyl, benomyl, captan and zineb. Captan controlled both thiophanate methyl-resistant and iprodione-resistant isolates as effectively as sensitive isolates.

This study is to analyze the effects of geography class using taboo games on developing student's ability to think. After playing taboo games in which students explain keyword without using presented taboo words, worksheets of participants were analyzed with interviews to demonstrate what kind of thinking skills are working. The results of the analyses are as follows. First, while divergent thinking is applied to students who explain keyword in taboo games, convergent thinking is applied to students who listen to and guess them. Second, as groups play a role as explainer or answerer in turn, they can learn divergent and convergent thinking together. Third, students seem to improve high-order thinking ability like decision-making, critical thinking, metacogniton through taboo games. Fourth, students have a tendency to use a variety of direct and/or indirect experiences (especially, from media) as well as cross curricular knowledge in order to explain keyword without using taboo words.

Anther and/or tissue culture of cross pollinated crops would be very important because it can result in the direct use of haploids or doubled haploids for developing superior hybrids or varieties. The objective of the study was to investigate the response frequencies in anther and/or tissue-cultured hybrids of corn. pearl millet and buckwheat to identify agronomically acceptable germplasm of the crops. 27 crosses of corn inbred lines were evaluated by plating their anthers on N6. MS and Yu-Pei media. Two genotypes of FR1l41/FR16 hybrid cultured on N6 medium and Fla 2BT73/S6013 hybrid cultured on N6 medium responded with one anther producing calli when plated after 5$^{\circ}C$ low temperature treatment for one week. Immature embryos of corn hybrid Suwon 19 responded producing calli that were regenerated to plants at a 8.6 percent success rate. Of the 20 corn hybrids. immature tessels of FR1l41/FR16. B68/A1l6N//KS15. KS16/KS17. GA209/DB578 and SDB126/GA209 crosses responded at a relatively higher success rate producing calli that were regenerated to plants. In tissue culture of elongating culms of pearl millet x Napier grass interspecific hybrid. 2.5-4.0mm long pieces of the culm were good for callus induction resulting in higher success rate. The epicotyl of buckwheat was very good for tissue culture. and the node produced the plants regenerated directly without callus induction on the B5 medium containing I ppm BA and 0.05 ppm IBA. There were great differences in response to anther and/or tissue culture of corn, pearl millet and buckwheat due to genotype x medium and environment interactions.

This study aimed to examine how video-recorded hearsay statements are taken in trial with regard to testimony of children less than the age of 13 in terms of children's rights, and to assess policy implications for the purpose of improving the current system. This study analyzed the precedents in accordance with their facts and contents. The analysis of the contents dealt with the main issues of trials concerning the sexual violence of children less than the age of 13. Specifically, This study selected precedents dealing with video-recorded hearsay statements, which are children's indirect statement, as core legal issues; examined the credibility(probative power) and admissibility of video-recorded statements; and prepared systemic alternatives in accordance with the United Nations Convention on the Rights of the Child, the international standards for the protection of children's rights. As a result, this study proposed creating and utilizing indicators to assess evidence admissibility and the credibility of video-recoded statements in trial, thus reducing judgement through judges' discretion. Also proposed are new regulations with regard to cross-examination coverage of the hearsay statement of a child in a sexual violence trial of concerning children less than the age of 13. This study suggests an improvement in legal policies, based given that children's rights are more vulnerable than those of adults in trial. Nevertheless, this study is limited in that it selected and reviewed only among precedents that are in the public record.

To prevent the secondary hospital-acquired infection (cross-infection) from occurring in the general radiographic room in the department of radiology, the microbial measurement was conducted at the points making direct close contact with radiologists and patients. For the case of radiologists, the microbial measurement and incubation were focused on the x-ray tube handle of the radiation generating device, and, for the case of patients, the microbial measurement and incubation were focused on the chin supporting device, chest-contact point, and handle. Once disinfected with Aniosurf, the sterilized media were gathered and identified, and the microorganisms were confirmed. Based on the identification results, it was confirmed that the points making direct close contact with radiologists showed a value of 103 CFU for Proteus mirabilis, Staphylococcus epidermidis, Bacillus spp. and Candida spp., and that the points making direct close contact with patients showed a value of 103~5 CFU for Proteus mirabilis, Enterococcu faecium, Pseudomonas aeruginosa, NTM(Non-Tuberculosis Mycobacteria) and Candida spp.. It was also confirmed that the types and number of microorganisms gathered from the points making direct close contact with patients were greater. Fortunately, most of the involved microorganisms were observed to be on the skin surface and are known to become extinct when disinfected in accordance with the hospital-acquired infection control rules. However, since even minor exposure to such microorganisms may be lethal for patients with reduced immunity, caution must be taken. In particular, since the points making contact with patients showed a high level of microbial measurement, it was thought that it would be necessary for radiologists and personnel having frequent access to strictly disinfect the parts, such as instruments and handles, making frequent contact with patients. The purpose of this study was to announce the importance of safe microbial control in the radiographic inspection room in hospital, and this study is expected to be used as the baseline data for preventing hospital-acquired secondary infection and Nth infectious diseases.

The purpose of this study was to find out the presentation of food and cooking process shown through the media and its cultural implications by comparing and analyzing seasons 1 and 2 of , tvN's reality program which has gained high viewer ratings and sympathy from the viewers. In light of the existing documents, the research reviewed the social and cultural meanings implied through a series of processes of "the act of cooking- the act of providing food - the act of having a meal."The authors concerned narrative structure of the program, paradigmatic analysis, actantial analysis, and analysis by applying the culinary triangle of $L{\acute{e}}vi$-Strauss were conducted, in order to find out the difference between seasons 1 and 2 of the . As a result of semiotic analysis on the programs, by focusing on the value of composure and slowness which may be felt through the simple everyday lives and travelling by running a Korean restaurant in a foreign country, the reality program revealed the changed consumption behaviors for Korean food, and the evolutionary process of cooking and the act of providing food reflecting the above. Meanwhile, the transformation of the Korean food may mean the "statelessness of Korean food" hidden under the name of localization or globalization. Furthermore, although the program intended to put up globalization of Korean food, the uniqueness of the Korean food wash armed, and this is the reason why it needs to be examined whether Korean food was used simply for entertainment in the program. Also, the program showed limitations such as drawing cultural inferiority as the motive for watching the program.

Proton therapy using the Bragg peak is one of the radiation therapies and can deliver its maximum energy to the tumor with giving least energy for normal tissue. A cross-sectional image of the human body taken with the computed tomography (CT) has been used for radiation therapy planning. The HU values change according to the tube voltage, which lead to the change in the boundary and thickness of the anatomical structure on the CT image. This study examined the changes in the Bragg peak of the brain region according to the thickness variation in the head phantom composed of several materials using the Geant4. In the phantom composed of a single material, the Bragg peak according to the type of media and the incident energy of the proton beams were calculated, and the reliability of Geant4 code was verified by the Bragg peak. The variation of the peak in the brain region was examined when each thickness of the head phantom was changed. When the thickness of the soft tissue was changed, there was no change in the peak position, and for the skin the change in the peak was small. The change of the peak position was mainly changed when the bone thickness. In particular, when the bone was changed only or the bone was changed together with other tissues, the amount of change in the peak position was the same. It is considered that measurement of the accurate bone thickness in CT images is one of the key factors in depth-dose distribution of the radiation therapy planning.

Recently, due to COVID-19, non-face-to-face online lectures are being held all over the world. In higher education in the post-corona era, distance learning has become the main teaching and learning method. At this time, Metaverse is being proposed as a new alternative. Metaverse has basic elements such as avatars, 3D space, and activities accompanied by interaction, which can be seen as a difference compared to existing VR (Virtual Reality) contents. This study designed and built an educational metaverse platform that can be applied to actual lectures by reflecting the three elements of the metaverse.In addition, we implemented a cross-device-platform that supports various devices such as HMDs, smartphones, tablets, and PCs by reflecting user requirements through usability tests such as middle school, high school, college students, and parents, so that anyone can easily participate in Metaverse lectures. Currently, the metaverse platform is being developed and serviced in various ways, but there are hardly any services designed for education. Just as services such as Zoom, the existing video conferencing solution, were used for non-face-to-face education, some functions of the currently serviced metaverse are utilized for education and used in the form of a one-time event. The educational metaverse platform developed through this study is expected to be a reference in constructing the metaverse for education in the future.
