. 최근 인구구조의 변화는 급속한 노령화로 요약되고, 이에 따라 제기되는 각종 노인문제는 각 부문별로 정책적 대응을 필요로 하고 있음. . 우리나라는 세계적으로 유래를 찾아볼 수 없을 정도의 속도로 노인인구가 급속하게 증가하는 가운데, 전통적으로 가족을 중심으로 하는 사적 영역에서 담당해오던 노인 부양기능이 약화되고 있으며, 낮은 출산율로 인해 청장년층의 노인부양 부담이 점차 더욱 커질 것으로 전망됨. - 특히 노년기의 보건학적 특성으로 인하여 보건 분야의 주요 현안들을 야기하고 있는데, 노인인구는 보건의료서비스에 대한 수요가 높은 집단으로 1인당 보건의료비용 또한 가장 높은 집단일 뿐만 아니라, 노인의 건강문제는 보건의료서비스 이외에 건강문제로 파생되는 다양한 사회적 서비스와 연계되어 있음. - ­이러한 사실은 한편으로는 우리 사회가 향후 노인의 건강문제로 인해 발생하는 높은 비용과 부담을 지게 될 것이라는 사실을 의미함과 동시에 다른 한편으로는 이에 대한 대책을 시급히 마련해야 한다는 것을 의미함.

최근 인터넷 기반의 웹 2.0의 시작으로 정보나 콘텐츠를 누구나 이용할 수 있는 인터넷환경이 제공되었다. 특히 소셜미디어를 통해 빠르게 공통관심사를 공유할 수 있는 커뮤니티를 구성하고 있으며, 온라인에서의 공동체는 개인의 정체성과 집단적 정체성을 교차하는 영역을 이루고 있다. 이러한 온라인 공동체에서 팬덤은 참여가 높고 사적 수준에서 결속력이 강한 공동체를 형성하는 집단이라고 할 수 있다. 본 연구는 이러한 문화 현상에서 유대관계가 강하게 형성된 '팬덤'이라는 이용자를 대상으로 이용동기 요인과 이에 따른 스타와의 상호작용을 통해 형성되는 커뮤니티의 충성도에 어떠한 영향을 미치는가를 알아보고자 한다. 커뮤니티 사례의 내용분석을 통해 팬덤의 일반화된 이용동기에 관해 살펴봄으로써 커뮤니티의 사용자 측면에서 시사점을 제시하고자 하였다.

There has been an increasingly high interest in gardens and garden design in Korea recently. However, the usage of the term 'garden' is extremely varied and complex, and there has been very little academic research made on the meaning of garden. Therefore, this research attempts to investigate the ideas of current gardens and to elucidate their changing patterns by means of extensive literature research and big data analysis. The notion of garden in the past was broad including not only private space such as Madang(마당) and Teul(뜰), but also even field and grass land as public outdoor space. Yet, the meaning has become smaller to merely private space due to the change of dwelling systems due to high industrial development of the 20th century. Furthermore, the introduction of urban parks as an interactive space between nature and humans, the similar spatial function of gardens, has blurred the boundary between garden and park, which created confusion in understanding the concept of a garden. After all, garden is a subject for humans. The meanings of garden need to be recognized from various points of view since garden itself is a creation by the sum of diverse fields such as natural and social sciences as well as culturology. This discussion on the meaning of garden in the present day will give a conceptual foundation for future research on gardens and garden design. Also, the big data analysis employed here as a research method can help other similar research topics, particularly semantics in landscape architecture.

Nowadays, organizations have adopted Smart Work to efficiently manage tasks, such as electronic document approval, customer management, and site inspection, without spatial-temporal constraints. Smartphones, which are commonly used in Smart Work, enable individuals to perform their jobs anytime and anywhere, thus blurring the boundary between work and non-work. To solve the problem of blurred work/non-work boundaries, a construct of self-control and affective factors needs to be considered because business style is changed from command to autonomy in the Smart Work context. Moreover, employees can convey their emotions easily over smartphones. Recent marketing studies have analyzed consumers' behavior based on the combination of cognitive, affective, and behavioral components, and researchers of information systems are also interested in these factors. However, previous research has some limitations, such as not classifying factors into cognitive, affective, and behavioral as well as not covering all three factors. Therefore, we explore the roles of cognitive, affective, and behavioral components in emotional exhaustion and education performance, and conduct a survey on undergraduate and graduate students, who are the major users of smartphones. Findings show that when individuals improve their cognitive capability (self-control) and usage experience (smartphone communication and internet usage), they can decrease emotional exhaustion and increase education performance. In the role of affective capability, increasing education performance is partially accepted. These results imply that organizations should not focus on controlling the usage of smartphones but on promoting appropriate smartphone usage.

This research was aimed to develop and apply the molecular genetics teaching program based on the history of science and creative problem solving model (HS-CPS model) for gifted students. Based on the strategies of creative problem solving and scientific theory development, the HS-CPS teaching program were developed. This program was applied to 8 first and second graders of the special class for invention activity in a high school. Creative problem solving ability in science and the understanding of DNA and gene concept were tested in pre and post of 12 lessons. The results were as follows: First, creative problem solving ability in science was improved meaningfully. Second, HS-CPS teaching program was effective in the understanding of DNA and gene concepts. Third, the students responded positively to the program evaluation questionnaire.

This study aims to examine the prospecting view of future society from a critical perspective, and to explore the direction of home economics education that can lead to transformation of future society from Habermas's critical theory. For this, Habermas's critical theory was understood, and the direction was explored in which field should act to guide future society when home economics education took a critical science perspective. Direction for praxis of home economics education was explored in both lifeworld and system area of society based on the critical theory that individuals, families and society are mutually beneficial and continue through interactions. The praxis of home economics education from a critical science perspective has been found through examples of IFHE's advocacy and policy participation activities. In conclusion, it supported the reason that home economics education as a critical science should form a social, political and economic system as well as lifeworld with valued human conditions and practice professional activities in academic, daily life and societal areas which will lead to the critical and participatory changes in individual and family life.

It is a hot issue to determine the spatial location and shape of tumor boundary in fractionated stereotactic radiotherapy (FSRT). We could get consecutive transaxial plane images from the phantom (paraffin) and 4 patients with brain tumor using helical computed tomography(HCT). K-means classification algorithm was adjusted to change raw data pixel value in CT images into classified average pixel value. The classified images consists of 5 regions that ate tumor region (TR), normal region (NR), combination region (CR), uncommitted region (UR) and artifact region (AR). The major concern was how to separate the normal region from tumor region in the combination area. Relative average deviation analysis was adjusted to alter average pixel values of 5 regions into 2 regions of normal and tumor region to define maximum point among average deviation pixel values. And then we drawn gross tumor volume (GTV) boundary by connecting maximum points in images using semi-automatic contour method by IDL(Interactive Data Language) program. The error limit of the ROI boundary in homogeneous phantom is estimated within ${\pm}1%$. In case of 4 patients, we could confirm that the tumor lesions described by physician and the lesions described automatically by the K-mean classification algorithm and relative average deviation analyses were similar. These methods can make uncertain boundary between normal and tumor region into clear boundary. Therefore it will be useful in the CT images-based treatment planning especially to use above procedure apply prescribed method when CT images intermittently fail to visualize tumor volume comparing to MRI images.

The mobile phone is a medium of mobility in the sense that it makes possible anytime, anywhere communications. It is also a medium of privatism as it opens for the users an exclusive communication space that marks private territoriality. These two characteristics associated with the mobile phone are usually interpreted as part of its technical properties and convenience it provides to the users. But mobility is offered not just for the sake of mobility, nor privatism is for the sake of privatism. There are certain social and political economic conditions that enhance and even force us to be mobile and private. The mobile phone symbolizes this kind of world order in which mobility and privatism condition our social life-world.

The current research intends to show the practice of the narrative-biographical interviews analysis developed by Rosenthal. As an example of this, the research analysed an interview with a Korean migrant worker in Germany in 4 stages as follows: 1. analysis of biographical data, 2. text and thematic field analysis, 3. reconstruction of life as lived and sequential fine analysis, 4. contrasting the life-story as narrated with life as lived. Based on the research, some implications for the biographical research in the social welfare and for the social work practice were addressed.
