본 논문은 디지털홈서비스의 실제 이용자들에 대한 실증분석을 통해 수용에 영향을 미치는 요인들을 밝히기 위한 연구이다. 디지털홈서비스의 특성에 맞게 기술수용모형 (TAM) 을 확장. 수정된 연구모형을 개발, 가설을 설정하여 분석하였다. 외부변수로 이용자의 특성을 채택하였으며, 디지털홈서비스가 가정 내 기술임을 고려하여 신념변수로 ‘지각된 이용용이성’과 ‘지각된 즐거움’ 외에 ‘지각된 편의성’, ‘지각된 안전성’, ‘지각된 삶의 질 향상’이라는 변수를 추가하였고 종속변수로는 ‘이용행동’을 설정하였다. 205명의 실제 이용자를 대상으로 한 설문조사 중 201개의 유효표본을 분석하였고, 신뢰성과 타당성 모두 통계적으로 적합한 것으로 나타났다. AMOS 4를 이용한 구조방정식 모형분석을 통해 24개의 가설검증 결과, 13개의 가설이 채택되었다. 이용자 개인의 특성 중 경험과 교육훈련은 지각된 이용용이성에 정(+)의 영향을 미쳤으며 혁신성은 지각된 즐거움, 지각된 편의성, 지각된 안전성, 지각된 삶의 질 향상에 대하여 정(+)의 영향을 미치고 있었다. 또한 지각된 이용용이성이 다른 신념변수인 지각된 즐거움, 지각된 편의성, 지각된 안정성, 지각된 삶의 질 향상에 정의 영향을 미치고 있었다. 종속변수인 이용행동에는 지각된 즐거움과 지각된 편의성, 지각된 삶의 질 향상이 긍정적인 영향을 미치나, 지각된 이용용이성과 지각된 안전성은 영향을 미치지 않았다. 가정에서 쉽게 이용할 수 있다는 것만으로는 적극적인 이용 행동을 기대할 수 없으며, 즐거움 및 실용적인 효익들의 제공 및 이를 위한 다양한 컨텐츠와 프로그램 개발 등이 매우 중요하다는 것을 시사하고 있다.수십억원의 추가적인 이익을 실현할 것으로 분석되었다. 본 알고리즘을 확장 적용할 경우 PBUC 문제 해결을 위한 새로운 해법으로도 그 효용성이 클 것으로 예상된다.자료이기 때문에 통계적 활용의 범위가 방대하다. 특히 개인, 가구, 사업체 등 사회 활동의 주체들이 어떻게 변화하는지를 추적할 수 있는 자료를 생산함으로써 다양한 인과적 통계분석을 할 수 있다. 행정자료를 활용한 인구센서스의 이러한 특징은 국가의 교육정책, 노동정책, 복지정책 등 다양한 정책을 정확한 자료를 근거로 수립할 수 있는 기반을 제공한다(Gaasemyr, 1999). 이와 더불어 행정자료 기반의 인구센서스는 비용이 적게 드는 장점이 있다. 예를 들어 덴마크나 핀란드에서는 조사로 자료를 생산하던 때의 1/20 정도 비용으로 행정자료로 인구센서스의 모든 자료를 생산하고 있다. 특히, 최근 모든 행정자료들이 정보통신기술에 의해 데이터베이스 형태로 바뀌고, 인터넷을 근간으로 한 컴퓨터네트워크가 발달함에 따라 각 부처별로 행정을 위해 축적한 자료를 정보통신기술로 연계${cdot}$통합하면 막대한 조사비용을 들이지 않더라도 인구센서스자료를 적은 비용으로 생산할 수 있는 근간이 마련되었다. 이렇듯 행정자료 기반의 인구센서스가 많은 장점을 가졌지만, 그렇다고 모든 국가가 당장 행정자료로 인구센서스를 대체할 수 있는 것은 아니다. 행정자료로 인구센서스통계를 생산하기 위해서는 각 행정부서별로 사용하는 행정자료들을 연계${cdot}$통합할 수 있도록 국가사회전반에 걸쳐 행정 체제가 갖추어져야 하기 때문이다. 특히 모든 국민 개개인에 관한 기본정보, 개인들이 거주하며

With wide distribution of smart phones and development of mobile network, social network service (SNS) is displaying remarkable growth rates. Users build new social relations by sharing their interests, which brings surging growth to the SNS based on the combination between the strength of expanding the place for communication and distribution of smart phones featured with easy portability. This study is designed to understand impact factors of SNS on users in Korea and to conduct empirical research on casual relationship between the factors above and the factors affecting personal information behavior through the privacy protection and self-efficacy. In order to accomplish the objective above, the study presented a research model applied with key variables of the Health Belief Model (HBM) predicting behaviors capable of recognizing and preventing individual diseases in the field of health communication. To perform empirical verification on the research model of this study, a survey was conducted upon college students at N university located in Chungcheongnam-do and K university in rural area, who have experiences using the SNS. Through this survey, a total of 186 samples were collected, and path analysis was performed in order to analyze the relationship between the factors. Based on the findings from the survey, first, variables Perceived probability, Perceived severity, Perceived impairment of the HBM, key factors of personal information protection behavior on the SNS, were found to exhibit negative relationship with self-efficacy, and Perceived probability, Perceived benefit, Perceived impairment were found to exhibit negative relationship with privacy protection. But the above, Perceived severity showed positive relationship with privacy protection, and Perceived benefit and self-efficacy also displayed positive relationship. Second, although self-efficacy, a parameter, showed positive relationship with privacy protection, it demonstrated negative relationship with personal information protection behavior. Lastly, privacy protection exhibited positive relationship with personal information protection behavior. By presenting theoretical model reflected with characteristics of prevention based on these findings above unlike previous studies on personal information protection using technologies threatening personal information, this study is to provide theoretical and operational foundation capable of offering explanations how to predict personal information protection behavior on the SNS in the future.

This study aimed to investigate teacher learning in the context of a community. For the purpose of this study, two research questions about the kinds of teacher noticing in a community and the role of partnership were addressed. To build a learning community, a professional development project, PRIME, established partnerships with 11 high schools and one of the cluster meetings were investigated in this study. Three mentor teachers, three preservice teachers, and one university supervisor participated in the cluster meeting. For this study, the multiple data such as audio tapes of cluster meetings, observation notes, and interviews were analyzed using the analysis of narratives. The results showed that the participants engaged in different kinds of noticing of their own beliefs about teaching and learning, teacher practices, and teacher identities including noticing of students' understanding in classroom situations. The partnership played the crucial role of reinforcing relationships among teachers, assigning tasks, and creating various communities.

This study investigates the development of meat analogues using vegetable proteins. Over the years, the consumption of meat analogues has increased because of environmental and religious concerns. Vegetable protein sources, especially soy, wheat, and peanuts, are commonly used as meat analogues. However, the texture of vegetable proteins does not resemble that of traditional meat. Thus, a number of studies have been conducted to improve the texture of vegetable protein-based meat analogues. The interest and demand for meat analogues, especially for recently released vegetable protein-based meat analogues, is expected to increase in the near future.

It's now time for adopting u-Health according to development of internet. It is judged that it needs to research on effect of using internet health information targeting University students who are the most sensitive of internet health information. So we analyzed effect of using internet health information according to internal and external health control materials with 300 University students. As a result, If a rate of investment to the health is high, an effect of internet health information also increases as B=.004, rate of internal health control is high, it decreases as B=-.027 and rate of external health control is high, it increases as B=.037. For a University student who has steady faith about health and can control their internal health more easily, the effect of using internet health information has decreased. And for a University student who has high inclination of external dependence about health and can control their external health more easily, the effect of using internet health information has increased. So it needs to raise credibility, accuracy and accessibility of internet health information.

The purpose of this study was to investigate the changes in teachers' recognition of science class and children for the gifted, and the process of changes in their practical knowledge after the experience of science class and conversation with colleague teachers. Two elementary teachers, teacher A and B, were selected as subject of investigation, who wanted to improve their science class. They experienced the process of self-examination during their class and from class conversations. Teacher A has 10 years of teaching experience. She has been in contact with gifted children and observed them since undergraduate. She entered the graduate school since she came to be interested in science class and children for the gifted. While teacher B has only three years of teaching experience and had a first contact with the gifted after graduate school. The results of this study are as follows. Teacher A didn't change recognition of gifted children class by class conversation in short term because she had a firm faith in good class teaching and was rich in class teaching knowledge. And, her practical knowledge was applied to the next class by changing teaching method or by supplementing her class contents in concerned part through class observation and class conversation with her colleagues. Teacher B was characterized as being lack of class confidence and concerned more about subject knowledge. She was forming a new practical knowledge along with new class teaching knowledge. Teacher B was in trouble with applying new practical knowledge to next class. From such findings, it was concluded that the process of changing or forming of practical knowledge depends on the beliefs, values, experiences, or knowledges of each teacher. A reflection on one' own class teaching could be a good way to form a practical knowledge and improve teaching speciality, when it was concerned with self-reflection of their own class, class observation, and communication with colleagues. Thus, the reflection practice could be applied to the teaching program of teachers for the gifted to form practical knowledge through trial class, self-reflection of class, and conversation with colleagues.

This study examined the changes of preservice biology teachers' NOS pedagogical content knowledge through two consecutive science methods courses: NOS understandings; attitudes toward teaching science; difficulties of NOS teaching; NOS teaching strategies; and views of orientation of NOS teaching. During the science methods course I, the preservice teachers engaged in discussions and reflections on what science is and how scientific knowledge has produced, drawing NOS aspects from episodes of history of science, and planning the lessons cooperating NOS instructional objectives. Then the next semester, through the science methods course II, the preservice teachers had a chance of the simulated teaching by adopting NOS teaching and learning activities in the context of the secondary biology context. The preservice teachers, further, reflected on their NOS teaching. The results showed that the preservice teachers constructed the NOS pedagogical content knowledge. They significantly improved their views of NOS and its teaching(p<.05) after the science methods course I, and retained their understanding after the science methods course II(p>.05). The preservice teachers mentioned the difficulties of teaching NOS in the secondary biology context, and further suggested effective NOS teaching methods in their reflective journals.
