The Yeongsan river estuary has a serious water quality problem due to the water stagnation and it is imperative to predict the changes of water quality for mitigating water pollution. EFDC(Environmental Fluid Dynamics Code) model was mainly utilized to predict the changes of water quality for the estuary. The EFDC modeling normally accompanies the large volume of modeling output. For checking the spatial distribution of the modeling results, post-processing for converting of the output is prerequisite and mainly post-processing program is EFDC_Explorer. However, EFDC_Explorer only shows the spatial distribution of the time series and this doesn't support overlay function with other thematic maps. This means the impossible to the connection analysis with a various GIS data and high dimensional analysis. Therefore, this study aims to develop a post-processing system of a EFDC output to use them as GIS layers. For achieving this purpose, a editing module for main input files, and a module for converting binary format into an ASCII format, and a module for converting it into a layer format to use in a GIS based environment, and a module for visualizing the reconfigured model result efficiently were developed. Using the developed system, result file is possible to automatically convert the GIS based layer and it is possible to utilize for water quality management.

This study's aim was to find a patterns of network dynamics focused on multicultural education contents within the teacher's guide books which are based on national kindergarten curriculum. It was analysed that the 43 guidebooks(2009 Educational activities and materials guidebooks for kindergarten, 11 and the Nuri curriculum teacher guidebooks for the age of 3-5, 32) were analysed using the UCINET 6 program with multicultural education contents frameworks. The findings were as follows: First, multicultural contents' density is connected to life theme of the Nuri curriculum was higher than the 2009 kindergarten curriculum. And life theme with high connectivity was 'I and my family' in the 2009 kindergarten curriculum and 'animals, plants and nature'(3 years old), 'kindergarten and friends' & 'I and my family'(4-5 years old) in the Nuri curriculum. Second, the highest connection content was 'having interests in culture' & 'knowing similarities and differences' in the 2009 kindergarten curriculum, and 'having interests in culture' & 'promoting a sense of community' in the Nuri curriculum. Finally, multicultural education for young children according to the national educational curriculum transition was changed from 'identity' to 'interaction and cooperation'. It means that the Nuri curriculum is more focused on international knowledges and competencies as a world citizen. It suggests the directions for multicultural education for young children in the future.

This paper aims to investigate the seismic characteristics of strip-type damping devices possessing optimized shapes for the moment-resisting mechanism throughout analytical and experimental studies. Predicting equations for initial stiffness and yielding strength were introduced and compared with analytical results obtained from finite element analyses (FEAs) using commercial FEA program ABAQUS. In order for establishing predicting equations, two idealized processes were considered and both predicting equations showed that they could provide enough approximations for seismic applications in building structures. Throughout experimental studies, it was noted that structural uncertainties on mild steels, connection details and structural types linking damping devices with building structures could interrupt predicting structural behavior of the devices. Also, it was observed that shear stress concentrations should be considered if shear yielding type devices are applied into building structures. Nevertheless, it was shown that structural conservatism can be established using the predicting equations and seismic applications of the damping devices can enhance the seismic performance of building structures efficiently in the viewpoint that they have high resistance to low-cycle fatigue failures.

This study selected 3D printing that is highly likely to be adopted in schools. This research was conducted in two stages: 1) proposing the learning activity framework for utilizing 3D printing in education, and 2) exploring the potential of integrating 3D printing in the school field. The '3D printing learning activity framework' proposed in this study includes four phases that are categorized according to the complexity of problem-solving processes and collaborative interaction: Step 1 as production through replication, Phase 2 as means of imaginary expression, Phase 3 as near problem-solving, and Phase 4 as expanded problem-solving. Next, we conducted the field study with 23 students in the 6th grade math class where they learned the various solid shapes and volumes through 3D printing-integrated activities. The lesson was considered as Phase 1, which is the production through replication. Overall, the results showed that the participants had positive perceptions about the efficacy of 3D printing activities, the quality of learning experience, and satisfaction. On the other hand, it was found that the usability of 3D printers and CAD program needs further improvement The contribution of this study can be found in the learning activity framework that can guide 3D printing activity design in school, and in the exploration of enhancing the connection between 3D printing activities and curricular relevance beyond simple interest toward a novel technology.

The purpose of this study was to analyze the association between family members and adolescent boys smoking. The data were evaluated by frequency analysis, 𝑥² test and logistic regression analysis using 27,276 people who responded to the 14th(2018) Korean Youth Risk Behavior Survey. Among male students, the nonsmoking rate was 91.5% and the smoking rate was 8.5%(2.5% of occasional smoking and 6.0% of frequent smoking). The study results showed that the smoking status of male students was varied significantly according to the number of smokers among the family members(p<0.001). Meanwhile, smoking based on the characteristics of socio-demographic factors was affected by grades, school records, economic status, and parents' educational background(p<0.001). Smoking by health factors showed a significant difference in alcohol consumption, suicidal thoughts, depression experiences, stress recognition, frequency of breakfast consumption, level of fatigue after sleep, and subjective perception of health(p<0.001). Male smokers were more likely to smoke when two family members smoked than only one(p<0.001). These results confirmed that smoking in boys was affected by the smoking status of family members and suggested that the smoking cessation program of family smokers can be effective in designing smoking cessation prevention and smoking cessation projects.

Recently, it is expected to significantly increase the defense budget by acquiring large-scale weapons systems to enhance defensive capabilities. In order to secure funds needed to acquire such weapons systems, it is necessary to improve the efficiency of the defense budget. In addition, interest in economic factors affecting the domestic economy such as export opportunities and employment creation are increasing, as well as budget reduction of the defense acquisition business. In order to respond to these demands, this study conducted cost- benefit analysis and examined economic ripple effects in the implementation of defense procurement projects. However, research on economic analysis methodology considering characteristics of defense acquisition projects is still in its early stage. This study proposes a methodology to analyze the economic feasibility of defense acquisition projects and conducted a case study on the economic feasibility of the ${\bigcirc}{\bigcirc}$ guided missile project which is being prepared against local provocation. The proposed economic analysis method provides the cost-effectiveness analysis that has been performed in many weapon system acquisition projects in connection with the more general cost-benefit analysis method. This study contributes to the establishment of an improved theoretical methodology for weapon system acquisition projects.

The purpose of this study was to identify the need for sex education in middle school students Research subjects were 194 students who attended at I seminary in B city. The period of data collection was from July to August, 2001. Research instrument was composed of 61 structured items 17 items related to demographics and sex, 44 items related to the need of sex education. Data were collected through the self-report method by the researcher and one trained assistant. The instrument developed by the researchers was employed to measure the need of sex education and it's Cronbach's $\alpha$ = 0.9349 in this research. Data were analyzed by frequency, percentage factor analysis and t-test using SPSS WIN Program. The findings of this study are summarized as follows : 1. The highest score among characteristics of sex was 'less interest about sex(42.6%)', 39.0% of subjects got information about sex from friends or elders. 52.3% of subjects consulted friends or elders about sex problems. The number of sex education lessons was 1-2 times in school during last semester (61.0%). Education by the school nurse was 35.9% to students. 43.1% of subjects announced moderate satisfaction on sex education. 2. The mean score of the need for sex education was $2.88{\pm}0.47$ (lowest value 1, highest 4). The most wanted sex education factor was 'chastity and sexual responsibility($3.33{\pm}0.67$)' and followed by 'family and marriage ($3.26{\pm}0.62$)' and 'considerations of sex($3.07{\pm}0.69$)'. Meanwhile, the lowest wanted sex education factor is 'physiological characteristics of male ($2.47{\pm}0.72$)', followed by 'sexual behavior ($2.49{\pm}0.75$)'. The most wanted sex education item was 'the meaning of family ($3.54{\pm}0.75$)' and followed by 'the cautions to prevention from sexual abuse ($3.49{\pm}0.78$)' and sexual activity and responsibility($3.43{\pm}0.77$)'. Meanwhile, the lowest wanted sex education item is 'masturbation ($2.16{\pm}0.97$)', followed by 'circumcision($2.32{\pm}0.97$)'. 3. There is no significant difference between boys and girls in mean score about the need for sex education(t=-.715, p=.476). Sex education factor that girl-students wanted was 'physiological characteristics of female'. Sex education factor that boy-students wanted was 'family and marriage'. Sex education items that girl-students wanted were 'cautions during menstruation', the relation of ovulation and pregnancy', caution to prevention from sexual abuse' and sexual behavior and responsibility'. Sex education items that boy-students wanted were 'the meaning of family', 'the importance of marriage', 'male's sex organs', 'a wet dream', 'the method to resolve sexual curiosity', 'sexual intercourse' and 'the connection with the other sex'. In conclusion, the mean score of the need for sex education is medium. The route to attain knowledge about sex and sexual problem is through consulting friends and elders. Therefore, it is necessary to give sex education that is suitable to the subject's needs and methods. Also, it is necessary to give differently strong point about sex education between female and male students.

Although this research puts the emphasis on the importance of the personality education, and lacks the understanding of the early childhood educator about the personality education, and essentially the content analysis of the direction of the operation of the personality education hasn't been performed. Therefore through the research study once again we collected the opinion of the early childhood educator about the personality education. As the object of the investigation, we questioned 208 teachers who work in the Daycare Center in the S city, and applied the SPSS 18.0 program. The result is as the following. First, there was a lot of concern in the understanding of the early childhood educator about the personality education, and that it was in need. The reason for emphasizing the personality education appears to be the "Individual Egoism", and the "Parental Value" as the factor of influence, and "Whole People Human Development and Health Promotion" as a factor of helping, and "Courage" as the inner information of the information of the personality education, and "Manner" as the outer information. Secondly, more than the majority was carrying out the personality education in the real state of the early childhood educator on the personality education and it happens to be that the instructional material is the "Material related to the personality education", "Conversation" as the teaching learning method, "Once per week" as number of times, "Within 30 minutes" as lead time, "Teacher in Charge" as the host, and "Uncooperative parents" as the difficulty. Lastly the accurate time of demanding the early childhood educator about the personality education happens to be from "Infancy", and the teaching method is "Teaching by making a connection with the family", and that "Leading by example of the teacher" is the factor of consideration.
