This study investigated whether there was a difference of the change in perspective of the nature of science depending on subjects of the history of science, after designing for two kinds of topics of role play programs based on the history of science to be transformed into a modern perspective. Before the history of science-role plays, the degree of the modern perspective was statistically no difference between group I(the atomic model transition-role play) and group II(the Mendeleev's periodic table-role play). However after treatment of the history of science-role plays for the each group, the degree of group I was higher than the degree of group II in the modern perspective. The results of this study indicate that the degree of changes into modern perspective of the nature of science by performing a history of science-role play may be depend on the subject of the history of science combined with the role play, and suggest the possibility that may be more effective to change the nature of science into the modern perspective, in case of performing of role play based on the history of science that includes the scientific knowledge established by a number of scientists with time series.

This study examined the difference between parents' and teachers' recognition about problem behaviors of children. The findings showed that there was a distinct difference between parents' and teachers' recognition about all problem behaviors of children. Especially, teachers had more recognition about problem behaviors of children than parents. And the reactive interaction and the actual prevention in educational institutions were preferred in the difference between parents' and teachers' recognition about a teaching strategy for children, such that teachers had significantly higher recognition about a teaching strategy for children than parents did, while there was no significant difference in the strategy for social emotion. This means that teachers should originally control and manage various problem behaviors based on the common teaching strategy, which is socio-emotionally recognized, rather than the biased teaching strategy. But the teaching strategy of reactive interaction is preferred in accordance with the type of problem behaviors between teachers and children and the children who show problem behaviors. Especially, teaching strategies of reactive interaction and actual prevention focused on the inhibition and prevention of children's problem behaviors are preferred in light of children's characteristics of many unexpected problem behaviors.

The purpose of this study was to investigate perception of snack purchasing behaviors and labeling of foods and nutrition of the middle school students. The survey was conducted from 424 students who are boys and girls of middle school in Naju. Data were analyzed by a SPSS program. According to the survey, snack purchase place had a significant difference between gender(p<.05), and all of the boys and girls responded at a high rate that it's convenience store. Snack eating frequency had a significant difference between boys and girls(p<.05). Boys responded that they ate 1~2 times per a week the most, and girls responded that they ate 1~2 times per a month the most. As for snack purchasing behaviors, depending on gender, that of boys was 2.76 in average and that of girls was 2.87, lower than middle. The reason why students didn't check up food labeling, depending on gender and all of the boys and girls responded 'Expiration date' was first confirmed. As for the understanding of food expression, depending on snack expenses, the reason why food expression contents were hard showed a significant difference, depending on snack expenses(p<.05). As for the understanding of food expression, depending on snack purchase attitude, the students showed a significant difference, depending on snack purchase attitude(p<.001), and the lower the snack purchase attitude was, the less the students checked up snack expression. The reason why students checked up nutrition labeling a significant difference, depending on gender, snack expense and snack purchase attitude(p<.001). 'Weight management' was the highest. The recognition in the necessity of nutrition expression(p<.001) and the necessity of food/ nutrition education and publicity(p<.01) showed significant difference.

The Purpose of this study is to observe the existence of welfare attitude split between welfare regimes clique and to explore the effect of institutional(regime) characteristics on welfare attitude. And Second purpose is to find the characteristics of structure of welfare attitude and then to clarify the characteristics of welfare attitude in Korea. This work contribute to find the point of solidarity and split and to work out the strategical clues for constructing pro-welfare politics. To compare the attitude on the state responsibility about the welfare, Sweden, France, US, and Korea is selected. And the effect of sex, age, education level, income class, and labor status which are abstracted from existing welfare state comparative study are analyzed. The result show the difference in welfare attitude score between countries. The welfare attitude score is Sweden, France and US in order. the Score in Korea is lowest. In the case of the effect structure of welfare attitude between countries, there are no differences between Sweden and France. But the specific characteristics in US and Korea, are observed. And the effect structure of sex, class, labor status is equal in Sweden, France, and US. That is, women, people in low class, and people in low labor status more emphasize the state responsibility on the welfare. But the effect structure of age of US is different comparing other countries. In US, the old age is tend to less support the state responsibility. The education level operate as the effect factor in only US. And Korea show the different effect structure on the welfare attitude. This understanding about structure of welfare consciousness become the basis to construct the strategy for welfare state by proposing the point of consensus and conflict to conversion of welfare paradigm.

The purpose of this research is to examine the self-concept in the cyberspace, self-efficacy, relationship with friends, subjective well-being and academic grade among adolescents who are addicted to Internet and those who are not addicted to Internet. A total of 1,057 adolescents (male=545, female=512), 326 from middle school, 361 from high school, and 370 from special education school, participated in the study. The results are as follows. First, qualitative analysis of the conception of self in the cyberspace indicates that those adolescents addicted to Internet reported that in the cyberspace they have fun, followed by they are the same as in real life, they spend time in cyberspace and they can become an imaginary person. Those adolescents not addicted to Internet reported that in the cyberspace they are the same as in real life, followed by they spend time in cyberspace and they can become an imaginary person. When they play Internet games, majority of adolescents in both groups reported that it is fun, followed by they become engrossed and they become aggressive. Second, those adolescents who are not addicted to Internet had higher scores on self-efficacy than those adolescents who are addicted to Internet, including self-regulatory efficacy for learning, relational efficacy, and resiliency of efficacy. Third, the number of friends and close friends that adolescents who are not addicted to Internet were not significantly different from those adolescents who are addicted to Internet. However, those adolescents who are not addicted to Internet were more likely receive social support from friends and were less likely to be social excluded than those adolescents who are addicted to Internet. Fourth, those adolescents who are not addicted to Internet had significantly higher scores on subjective well-being than those adolescents who are addicted to Internet. Fifth, those adolescents who are not addicted to Internet had significantly higher scores on both subjective and objective academic grade than those adolescents who are addicted to Internet.

최근 음성 인식 기술의 발전으로 음성 인식 시스템의 실용화가 점차 증가함에 따른 가장 큰 문제점은 음성 인식기의 인식환경과 학습환경과의 차이로 인해 음성 인식기의 성능이 급격히 떨어지는데 있다. 이를 해결하기 위해 본 논문에서는 기존의 잡음처리 방법 중 CMS(Cepstral Mean Subtraction)와 환경 잡음 (부가 잡음, 채널 왜곡)을 동시에 추정하는 최신 모델 보상 기법인 VTS(VectorTaylorSeries)를 소개하고 그 성능을 비교하였다.

The study examined moderating role of thinking style about causality in the relationship between the perceived brand globalness(PBG) and the brand evaluation. Thinking style about causality is divided into interactionism and dispositionism. Individualism culture shows a tendency of thinking style about causality to dispositionism, and collectivist cultures shows a tendency for interactionism. We conducted a survey on Korean college students who represent collectivist cultures and foreign students from countries of individualistic culture and analyzed data through structural equation modeling. Analysis result showed that the higher the respondents perceived PBG, the higher they perceived brand quality, brand quality, and brand price. However, it showed that PBG has greater positive effects on perceived brand quality and perceived brand reputation among Korean students than students from individualistic cultures. On the other hand, the effects of PBG on perceived brand price did not show any significant difference between Korean students and students from individualist cultures. Thus, we can conclude that thinking style about causality plays a moderating role in the relationship between PBG and perceived brand quality and brand reputation, while it does not do so between PBG and perceived brand price.

Purpose: We conducted a descriptive correlational study to determine a relationship between nurses' awareness of good death and attitudes toward terminal care, which in turn could be used as basic data for improvement of the quality of terminal care at geriatric hospitals. Methods: From April 3, 2013 through April 22, 2013, data were collected from 230 nurses working at geriatric hospitals. Results: Nurses' attitudes toward terminal care showed no significant correlation with awareness of good death, but it was positively correlated with a sense of closeness, a subfactor of awareness of good death. There was negative correlation between emotions regarding a deathbed, a subfactor of attitudes of nurses in charge of terminal patients, and awareness of good death. We found positive correlation between terminal care performance and awareness of good death. Conclusion: This study warrants the need for nursing education catered to characteristics of geriatric hospitals and development of diverse intervention strategies to help them to attain a positive attitude toward death by familiarizing themselves with the concept of good death and enhancing job satisfaction.
