Currently a KTX train of 20-car formation is 388m long and carries 931 passengers including one captain and three crews which is quite a few to cover the lengthy service area and many customers. On the other hand, if a passenger wants to talk to an attendant, he has to wait for an attendant passing by his/her seat or walk to an intercom which is placed at every other car. Any of these choices is inconvenient. So, in this paper, we presented a system design for developing an audio/visual communication system for a passenger and an attendant. The system was analyzed and designed according to the Object-Oriented methodology with UML (Unified Modeling Language). Based on a problem statement, a Use-case Diagram, Sequence Diagrams, Class Diagram, State Charts, collaboration Diagram were generated. The design will be used in system implementation to a HEMU-400X test train and to be tested.

We have carried out VLBI test observations of the Korean VLBI Network (KVN) at 22/43-GHz in collaboration with Japanese VLBI Exploration of Radio Astrometry (VERA). In order to evaluate the VLBI system of KVN, we have observed several sources using KVN+VERA. They consist of Active Galactic Nuclei (AGNs), which are expected to be compact and to have very well-known structures at spatial resolutions of 50-250 Mega-wavelengths, and Galactic star-forming regions and late-type stars, which have bright H2O and SiO maser emission regions. We have investigated baseline and imaging sensitivities of KVN+VERA. In this talk we report the preliminary results.

In the present study we have attempted to explore the relationship between family support that young people receive and the level of Ego Identity that they develop. We started the present study with the purpose of providing parish nurses with some basic data for nursing intervention for family and school nursing, as well as for community health care. We conducted the present study during the period of October 15, 2001 through November 5, 2001. The objects of this study were Inmunge High School students chosen from a school in Daejon. The subject students were selected randomly from each grade in that school. The numbers of subjects selected were 120 boys and 113 girls (total: 233). The research tool that we used to measure perceived family support received by students was one that Ga Eon Lee revised for high school students on the basis of Cobb's theory. To measure the subject students' Ego Identity level we used Bong Yon Sho's 'Ego Identity Scale', that he revised from Dignan's 'Ego Identity Scale' for Korean high school students. Data were analyzed with SPSS Win 10.0 program using statistics of frequencies, percentage, t-test, ANOVA, and Pearson correlation coefficient. The findings of the present study indicate that: 1) The mean of family support that the subject students feel that they received was 39.99 on the family support scale, and the mean of the students on the Ego Identity scale was 186.16. 2) The support that the subjects received from their own family had a statistically significant correlation with their Ego Identity (r=.93, p=.00). 3) Various factors had a significant correlation with the level of family support perceived by the subjects: the subject's grade (F=3.35, p=.04), the subject's religion (t=6.39, p=.00), the family's economic situation (F=9.14, p=.00), the birth order (F=27.61. p=.00), the father's education (F=23.17, p=.00), the mother's education (F=28.70, p=.00), parental relationship (F=2657.03, p=.00), and the structure of the family (F=-9.65. p=.00). 4) Various factors had a significant correlation with the level of the subject's Ego Identity: the subjects religion (t=6.20, p=.00), the family's economic situation (F=12.56, p=.00), the birth order (F=22.85, p=.00), the father's education (F=10.37, p=.00), the mother's education (F=20.69, p=.00), parental relationship (F=938.73. p=.00), and the structure of the family (F=-8.74, p=.00). 5) Analyzing sources of support within the family, family members whom the subjects trust most (F=3.08, p=.03) and family members to whom they talk most (F=5.85, p=.00) showed the most significant differences. Analyzing sources of support within the family that affect the level of the subjects' Ego Identity, family members whom the subjects trust most (F=3.30. p=.02) and family members to whom they talk most also showed the most significant differences.

This study is designed to provide some basic materials for finding better ways to promote student-parent communication in order to elevate the sense of self-esteem among middle school students and to talk about the importance of communication between students and parents through looking at the current student-parent communication reality resulting from socio-demographic changes among male and female middle school students and analyzing some influences student-parent communication has on students' self-esteem. To attain the aforementioned purpose, total 650 2nd grade and 3rd grade middle school students were asked to fill out the questionnaire. The schools that they are attending are 2 schools in Gwangju City and 2 schools in a township in Jeonnam. 617 students responded to the survey. In order to see the general characteristics and the distribution of major variables of the respondents, the data were used to produce frequency. percentile, standard deviation and correlation quotient. and t-test. one-way Anova, Duncan's multiple range test and multiple regression analysis techniques were put to use. The results from this study are as follows: student groups that have good relations with other students seemed to be more open and active in their communication with their mother and father. Female students and students in their 2nd grade had more open talking relations with their mothers than male students and students in their 3rd grade. Students had more open talking relations with their father when father's occupation is office worker. In the difference of self-esteem that results from variables in communication between students and parents, a significant variance was presented in the level of the self-esteem of middle school students. When they had open communication with both parents, they had a high sense of self-esteem. and when their communication style was problematic, they had a low sense of self-esteem. When they had better relations with other students, when they had more open communication styles with their mother, when they had better school records, when they felt more satisfaction with communication With their father, they showed a higher level of self-esteem.

Gold wire has long been used as a proven method of connecting a silicon die to a substrate in wide variety of package types, delivering high yield and productivity. However, with the high price of gold, the semiconductor packaging industry has been implementing an alternate wire material. These materials may include silver (Ag) or copper (Cu) alloys as an alternative to save material cost and maintain electrical performance. This paper will analyze and compare the electrical characteristics of several wire types. For the study, typical 0.6 mil, 0.8 mil and 1.0 mil diameter wires were selected from various alloy types (2N gold, Palladium (Pd) coated/doped copper, 88% and 96% silver) as well as respective pure metallic wires for comparison. Each wire model was validated by comparing it to electromagnetic simulation results and measurement data. Measurements from the implemented test boards were done using a vector network analyzer (VNA) and probe station setup. The test board layout consisted of three parts: 1. Analysis of the diameter, length and material characteristic of each wire; 2. Comparison between a microstrip line and the wire to microstrip line transition; and 3. Analysis of the wire's cross-talk. These areas will be discussed in detail along with all the extracted results from each type the wire.

Purpose: To identify the effects of a smart program for the patients who underwent percutaneous coronary intervention (SP-PCI) on coronary disease-related knowledge, health behaviors, and quality of life. Methods: A nonequivalent control group with a non-synchronized design was utilized and 48 participants (experimental=22, control=26) were recruited from a university hospital in Gyeongsang area from May to December, 2016. The 12-week SP-PCI consisted of self-study of health information using smart phone applications (1/week), walking exercise (>5/week) using smart band, feedback using Kakao talk (2/week), and telephone counseling (1/week). Patients in the control group received usual care from their primary health care providers and a brief health education with basic self-management brochure after the PCI. Data were analyzed using the SPSS 21.0 program through descriptive statistics, $x^2$ test, and t-test. Results: After the 12-week SP-PCI, the experimental group showed higher levels of coronary disease-related knowledge (t=2.43, p=.019), heart-related health behaviors (t=5.96, p<.001), regular exercise (Z=-4.47, p<.001), and quality of life-MCS (t=3.04, p=.004) and showed lower levels of stress (Z=-3.53, p<.001) and sodium intake (t=-4.43, p<.001) than those in the control group. There were no significant group differences in medication adherence and food intake in total energy, lipids, and cholesterol. Conclusion: The suggested SP-PCI provided easy access and cost-effective intervention for patients after PCI and improved their knowledge of the disease, performance of health behaviors, and quality of life. Further study with a wider population is needed to evaluate the effects of SP-PCI on disease recurrence and quality of life for patients after PCI.

One of the difficulties of female-headed families face is economic hardship. Low-income single mothers work long hours, become isolated and feel burdened for dual roles. And many of them don't have relatives to share parenting roles. As a result, children of low-income female-headed families are easy to be neglected and left to form a delinquency-prone group in neighborhood. Traditionally, it has been viewed that children in female-headed families have problems due to the loss of father role. However, study indicates that these children can adjust well if the relationship between mothers and children is consistent and adequate. An Intervention program for low-income female-headed elementary children was developed and delivered in two community social welfare centers. The purpose of the program is to raise self-esteem. Two goals were 1) management of daily living habits and 2) improvement of family relations. Social workers maintained contact with mothers to talk about children's behaviors and to prompt hugging and touching. In addition, workers helped children to form good relationships with peers and school teachers. Children were satisfied with the program. Their family relations were improved statistically significantly after the program(wilcoxon signed rant test z=-2.934 p<.05). However, their self esteem were not improved significantly (wilcoxon signed test z=-1.173 p>.05). Qualitative analysis of each children were also discussed. The implications of the study are the followings: Intervention programs need to be delivered separately for low-grade and high grade elementary children because they have different developmental needs. The program also need to include education on sex and marriage as well as aggression reduction. Society needs to provide more support to single mothers for their personal and parenting needs.

This study explored how South Korean newspapers covered North Korea's second nuclear test in May of 2009. Findings show that South Korean newspapers mostly reported North Korea's nuclear experiment in relatively negative tones. Their coverage mainly focused on the influences of nuclear threat from the North on the military, political and economic areas in South Korea. However, the media's agenda settings and frames were not similar in terms of each paper's political and ideological inclination. Whereas the progressive papers, such as the Hankyoreh and the Kyunghyang Shinmun, recognized that the current nuclear issue in Korean peninsula is getting worse because of South Korea's rigorous pressure on North Korea, the conservative papers, such as the Chosun Ilbo and the Donga Ilbo, see that the deadlock between North and South mainly comes from the system malfunction of North Korea. To prevent the current impasse, the left-side papers emphasized to develop the six-party talk in dealing with North Korean issue, while the right-wing papers paid attentions to the West's sanctions on North Korea and ensuring national security.
