The present paper deals with the results of the experiments, in which the resistibility to NaCl in whole develomental stages is examined by the emergence rate and the effects of NaCl on the SD action in Drosophila melanogaster. The four SD strains and one mutant strain(cn bw)are used and NaCl media are prepared y adding NaCl at a concentration of 1.0M, 0.7M, 0.5M, 0.3M, 0.1M, and 0.0M to the standard media for the present investigations. The results are given below. 1. The emergence rate (resistibility to NaCl) is not significantly different among strains but strikingly different among concentrations of NaCl. 2. The emergence rate decreases as the concentration of NaCl increases; the four SD strains are considerably resistible to the NaCl from a concentration of 0.0M to 0.3M but are susceptible from 0.5M or higher concentrations of NaCl. 3. No eggs are hatched from the culture media containing a concentration of 1.0M NaCl. This suggests that the SD strains are not resistible to NaCl at a concentrations of 1.0M or higher. 4. The difference in k values is not signficant among strains and also among concentrations of NaCl. Thus the SD action is not affected as far as once emerged from the culture media whether containing NaCl or not.
This study explored the lived experiences of high school students who experienced a norm-referenced evaluation with the Naesin system. The participants were 15 high school students who resided in the areas of Seoul, Gyeonggi, and Busan. This study adopted a phenomenological research method, which is developed by Giorgi. The study resulted in 370 meaning units, 71 summaries of meaning units, 26 sub-constituents, and 9 constituents. The results showed that participants experienced their relationships with classmates were centered around competitions and they experienced the sense of repeated frustration with their academic goals. Participants perceived that their personal values equated with their academic rankings and they anticipated academic rankings becoming their future social rankings. Low rankings with good performance, learning for exam, and unfair treatment in school made them realize that the education is not for learning but for differentiating students. Participants have found the ways to know better about reality and self-regulated their thoughts and emotions. Further, this study identified resilient aspects of the participants such as support from parents and teachers and hopeful thoughts. This study discussed the meaning of the findings and implications of the findings.

The core of this study is to develop an edutech utilization program to be applied to 5th grade students by utilizing school curriculum time, and the conclusions based on the results of the study are as follows. First, for the development of future educational programs using edutech, a content preference survey was conducted and significant responses were confirmed from 27 teachers and 216 students, excluding missing values. In the future education implementation, UCC (video shooting, editing, etc.) and work activities (3D pen, 3D printer, etc.) were selected based on the need for separate edtech devices. Second, in order to develop a future education program using edutech, the future education class module was set in 4 stages based on previous research. First of all, in Make a foundation, theories by subject are developed, and in Open an activity, future education experience activities using key edutech are developed. In Organize evaluation, individual self-evaluation was conducted, and based on this, customized in-depth supplementary activities were conducted in Act individually. Third, in order for future education programs using edutech to be organized in the regular curriculum, sufficient connectivity with the curriculum must be secured. The basis for systematic and stable research was prepared by analyzing the curriculum of the 5th grade subject of the study and securing hours in connection with creative experiential activities. The data developed through this process were modified and supplemented based on the content validity test. The fact that the program application and verification steps were not performed is a limitation of this study, but it is expected that this program will expand the possibility of future education practice in the school field.

The purpose of this study was to investigate the effects of an animal-mediated therapy program on children with developmental disabilities on social skills related to social-emotional development and learning, which are important in modern society. The subjects of the study were children with developmental disabilities at a special school, and the animal-mediated therapy program consisted of 12 sessions. The study was divided into experimental and control groups and conducted pre- and post-test by measurement items. SPSS 25.0 was used to analyze the data. First, children with developmental disabilities in the experimental group who participated in the animal-mediated therapy program showed a significant difference (z=-2.20, p<.05) in the overall social-emotional development compared to the control group, and statistically significant values were found in the subfactors of non-dependence on teachers, interaction with peers, and achievement motivation. Second, the experimental group who received animal-mediated therapy showed a significant effect (z=-2.20, p<.05) in all factors of learning-related social skills. In conclusion, animal-mediated therapy was found to have a positive effect on the social-emotional development and learning-related social skills of children with developmental disabilities. Based on the results of this study, it is recommended that more specific and systematic programs should be developed and applied to enhance the social-emotional development and learning-related social skills of children with developmental disabilities for a healthy life.

The purpose of this study was to examine students' experiences in the dietary life class using traditional Korean desserts in middle school home economics classes. Participatory observation, in-depth interview, and site data collected in this study were analyzed through emic coding, and the results are as follows. First, students had 'expectations about Han-gwa lab classes.' Students were always positive about lab classes, looking forward to eating delicious food and eagerly awaiting their first lab class since entering middle school. Additionally, there were many students who were experiencing Han-gwa for the first time, so expectations about learning about Han-gwa were high. Second, students engaged in 'self-directed learning through the Han-gwa project.' In other words, while creating an activity book about Han-gwa, the students realized self-directed learning about the differences between Han-gwa and Yang-gwa (Western-style sweets), and the scientific principles of cooking Han-gwa. Third, students had 'instilled pride in Han-gwa through lab classes.' The students learned that there was sufficient awareness and change in values to cherish Han-gwa and to inherit its traditions. Fourth, there was a 'potential curriculum effect.' Students who did not experience face-to-face group activities for three years in middle school due to COVID-19 came to recognize the importance of collaboration and even tried making Han-gwa at home. In order for students to have pride in Han-gwa, it was confirmed that it was necessary for home economics teachers at school to actively teach classes on traditional foods and provide students with many opportunities to encounter them.

The purpose of this study was to develop and evaluate the sustainable housing teaching-learning process plan aimed to achieve the global SDGs through home economics class in middle school that is based on the ADDIE model. The overall objective of the plan was to contribute to cultivating students' sustainable housing values and to creating sustainable lifestyle through everyday practice. The plan consisting of 4 lessons contained various activity and visual resources(4 individual and 4 team activity sheets, 4 reading texts, 1 homework sheet and 1 evaluation sheet, and 7 videos) for students and (4 sets of ppt and 4 reading texts) for teachers. The theme and team activities of each lesson were related to 2~7 targets of 2~3 SDGs, in total 11 targets of 5 SDGs. The plan was implemented to 4 classes of 127 senior students at Y middle school in Cheongju city during the period from the 29th of August to the 18th of September, 2019. The results showed that students were very positive and highly satisfied with not only practical contents but also adequacy of resources and activities of the whole 4-lessons, so that they actively participated in the lessons more than usual and looked forward to learning more about it. They thoroughly enjoyed various team activities such as brain writing, mandal art, visual thinking, making UCC, and planning the sustainable village as well as writing a short reflective journal at the end of each lesson. Students also reported that they highly accomplished the goal of each lesson and the overall objective. It could be concluded that the teaching-learning process plan of 4-lessons could contribute to cultivating students' sustainable housing values and to creating sustainable lifestyle through practicing everyday life. It indicates that home economics is one of the major subjects to contribute to the attainment of global issue of SDGs for OECD education 2030 and to educate the practically acting global citizen.

A survey has conducted on two hundred high school students of the first and second grade by way of questionnaine in Seoul. The purpose of this study on the information from the survey is to cstimate the level of awareness and probe how they feel and what they wish on sex. X2 inspection is designed to assess general aspects of responded contents by way of percentage and examine degree of satisfaction on previously experienced sex education and demand for sex education. The result is as follows. 1. As a result of the examination of degree of awareness on sex of respondents, 62% delines sex as human relationship including moral values for harmony between men and women. 64% of the men and 70% of the women say that sex is a natural thing. It comes to the conclusion that most of the respondent sgenerally consider sex positive. On chastity, 68.5% of the respondent answer that it means physical chastity, 12.5% that chastity before marriage should be kept, and 43% that it should be kept as far as possible. Most of them pespond that it should be kept. 2. As a result of the examination on the contents of sex, they answer they know well in the order of masturbation(72%), pregnancy(76%), and sex(63%). Contraception, abortion and ejection are contents they poorly informed of. 3. As a result of the examination on experienede of sex education, 83% of men and 100% of women have experienced sex, education, but their degreeof satisfaction to it is very low. And 49% of the whole is dissatisfactory to it. There is some difference between male and female students.(p=0.000) That result translates that female studeuts are educated on sex tjhrough more systematic subjects than male ones. In addition, it turns out that teenagers get most information on sex through friends, seniors, and mass media such as videos, TV and radios. Correct and systematic sex education is need because wrong information on sex culd be taught and bring them to misbehave. 4. 87.5% of the respondents answer that sex education is necessary, so that degree of necessity for sex education, turns out to be very high. Also the main subject that should perform sex education is in the order of school(50%), Society(24.5), home(18.5%). They respond that most appropriated period for the beginning of sex education is about elementary school age(43%), and 34% believes it to be put ahcad of elementary school age. Anurse teacher accounts for 54% for the main subject that addresses sex education, to male students visit teachers are most favored for 50%. As a result of those, it could be concluded that most high school students want sex education from responsible persons who have systematic and professional knowledge on sex. 5. In order to perform proper sex education by the above results, better educational effects are obtained when characteristics and natures of teenagers are known and most wanted knowledge by them is taught in priority in times of planning sex education. Besides, the contents of sex education suitable for each school should be planned before elementary school age and sex education should be performed in accordance with students' demand. In addition, sex education should be attentively performed by home, all organizations of society as well as school. Therefore, sex education will play a great role in making teenagers reestablish their conception on sex when the traditional and moral value systems of our country and the new value systems which are being formed under the influence of the western culture are in harmony.

The method to generate a digital elevation model(DEM) from contour lines causes a problem in which the low relief landform cannot be clearly presented due to the fact that it is significantly influenced by the expression of micro landform elements according to the interval of contours. Thus, this study attempts to develop a landcover burning method that recovers the micro relief landform of the DEM, which applies buffering and map algebra methods by inputting the elevation information to the landcover. In the recovering process of the micro landform, the DEM was recovered using the buffering method and elevation information through the map algebra for the landcover element for the micro landform among the primary DEM generation, making landcover map, and landcover elements. The recovering of the micro landform was applied based on stream landforms. The recovering of landforms using the buffering method was performed for the bar, which is a polygonal element, and wetland according to the properties of concave/convex through generating contours with a uniform interval in which the elevation information applied to the recovered landform. In the case of the linear elements, such as bank, road, waterway, and tributary, the landform can be recovered by using the elevation information through applying a map algebra function. Because the polygonal elements, such as stream channel, river terrace, and artificial objects (farmlands) are determined as a flat property, these are recovered by inputting constant elevation values. The results of this study were compared and analyzed for the degree of landform expression between the original DEM and the recovered DEM. In the results of the analysis, the DEM produced by using the conventional method showed few expressions in micro landform elements. The method developed in this study well described wetland, bar, landform around rivers, farmland, bank, river terrace, and artificial objects. It can be expected that the results of this study contribute to the classification and analysis of micro landforms, plain and the ecology and environment study that requires the recovering of micro landforms around streams and rivers.
The purpose of this research is to compare and analyze differences in modern 'Hyo' concepts and behaviors between the gifted and the general students of the elementary school. In this study, two groups(the gifted and the general students of the elementary school) were compared, in grade, birth-order, family members, education and religion factors in family, to seek for a better way to teach the Korean gifted students. The results are, as follows. First, the gifted had higher 'Hyo' concepts than the general students, because developments of the gifted in the field of intellect, emotion and will are faster than the general. The gifted had many interests in values and moral decisions. There are no meaningful differences between boys and girls in the gifted group. But in the general group, girls have higher 'Hyo' concepts than boys. This is because girls emotional developments are faster than boys. Second, in the gifted group, 5th graders have higher 'Hyo' concepts than 6th graders. On the other hand, in the general group, there are no meaningful differences between 5th graders and 6th graders. Third, there were no differences between the groups(gifted/general) by birth-order, family members and having religions or not. However, the comparison between nuclear families and large families shows that Korean traditional ethics - 'Hyo' is still in existence as a basic concept in the family, in spite of the changing family size and unit. In addition, in the family with a religion, the' Hyo' concept is revealed stronger than the other group. This is caused by the power of commanding love and affection which are emphasized through religions. From the results of this research, the gifted students of the elementary school have high consciousness concerning 'Hyo' concepts and behaviors. It is very essential for them to improve their 'Hyo' concepts until adulthood. Therefore, teachers and parents should pay more attention to help them improve their senses of Korean traditional morality - 'Hyo'.
Previously, we analyzed for nutrition knowledge and the use of nutrition knowledge in the everyday lives of students in order to develop nutrition education programs that focus on desirable behavior change. From this, we found that female students desired to participate in nutrition education more than male students, and regarding their concerns for nutrition education, 73.2% of the females and 50.0% of the males displayed interest in 'obesity and the regulation of body weight'. Therefore, this study showed female students give more attention to the obesity and the regulation of body weight than male students(p=.000<.001). In addition, female students had higher interests($8.63{\pm}1.67$) than male students ($7.45{\pm}2.03$) in nutrition knowledge(p=.000<.001). By investigating the use of nutrition knowledge in everyday life, our research indicated that the actual use of nutrition knowledge was less. To encourage students to persue dietary lives addressing the concerns confirmed above, the following needed to occur. 1) Provide them nutrition information for the main processed foodstuffs encountered when dining out(breads, cakes, cookies, and carbonated beverage). 2) Teach them to read food nutrition labels. 3) Help them find a lifestyle connection through lasting self-management methods and the generation of social support. Accordingly, this required developing effective and practical nutrition education programs that considered regional characteristics and gender differences. The most important factors considered during nutrition education program development were the need for motivation and ongoing education by stage of change, rather than temporal education through specific problem analysis, in order that those being educated may bring about a change of behavior by themselves. Therefore, from this study, we have suggested the use of multilateral operating strategies for successful nutrition education. In addition the phase model of behavior change should be applied. Our programs were aimed at self owned nutritional management so that students could master their own methods for acquiring skills and enjoying dietary life. The research may be summed up as follows. First, the purpose of education at the recognition stage of change was to attempt motivation for nutrition improvement, by analyzing the problems such as food buying habit and the main purchasing viewpoints when dining out. Second, the purpose of education at the action stage of change was to help students acquire of concrete methods for behavior modification by linking the program to their home as well as to teachers with various activities that suited the situation at school. This was done by analyzing the processes and decisions pertaining to dining out the main processed foodstuffs and principal components, etc. through data and experimental practice. Third, the purpose of education for changing of habits and values, or the maintenance stage, was to investigate the various reasons that undesirable behaviors were induced, and then determine a lasting self-management method as well as how to generate social support. If the nutrition education program developed in this study is utilized on site, someone in the primary role as the nutrition educator and trained specifically in nutrition, can help induce the health promotion in the community as well as lasting dietary management, by executing a link with families in parallel with educating teaching staff and students' parents. In addition, this program can playa role in the government policies related to the health promotion for our youth who are the foundation of our nation and who can enhance our national competitive power.
