현재 행해지는 과학관련 사회적 이슈(socio-scientific issue: SSI)에 대한 대중의 인식 조사는 대개 현상의 위험성 인식 및 정책 선호도와 같은 일부 영역에 한정되어 있다. 이에 본 연구에서는 특정 SSI에 대한 대중의 과학문화소양을 보다 다각적이고 총체적으로 살펴볼 수 있는 지표체계를 개발하고자 하였다. 이를 위해 연구자들은 최근 세계적으로 관심의 초점이 되고 있는 기후변화를 특정 SSI로 선정하였으며, 이 이슈를 중심으로 새로운 지표체계 및 설문지를 개발하였다. 먼저, 문헌연구를 바탕으로 'SSI에 대한 과학문화소양'을 '다양한 측면에서 SSI를 바라보고, 이를 통해 합리적인 의사결정을 하며, 관련된 문제에 현명하게 대처해나가는 생활양식'이라 정의하였다. 보다 체계적인 접근을 위하여 개인의 과학문화소양을 잠재적 소양과 실행적 소양으로 구분하였으며, 대범주 '잠재'는 중범주 '관심', '의견', '이해'로, 대범주 '실행'은 중범주 '학습', '실천'으로 나누어 지표 및 설문항목을 구성하였다. 개발 과정에서 과학교육, 환경 교육, 대기과학 전문가의 검토를 거쳤으며, 중학생 777명의 응답을 바탕으로 신뢰도분석과 요인분석 및 상관분석을 실시하여 통계적 타당성을 검토하였다. 그 결과, 지표체계와 설문지의 일부가 수정 보완되었으며, 수정된 지표체계는 2개의 대범주, 5개의 중범주, 15개의 소범주, 34개의 지표, 63개의 설문항목으로 구성되었다. 이는 신뢰도와 타당도가 비교적 양호한 것으로 검증되었다. 본 연구에서 개발된 지표체계는 향후 다양한 SSI 주제에 관한 대중의 인식을 조사함에 있어 종합적인 자료를 효율적으로 축적하고 분석할 수 있는 틀로 이용될 수 있을 것이다.

Object orientation has become the predominant paradigm for conceptual modeling (e.g., UML), where the notions of class and object form the primitive building blocks of thought. Classes act as templates for objects that have attributes and methods (actions). The modeled systems are not even necessarily software systems: They can be human and artificial systems of many different kinds (e.g., teaching and learning systems). The UML class diagram is described as a central component of model-driven software development. It is the most common diagram in object-oriented models and used to model the static design view of a system. Objects both carry data and execute actions. According to some authorities in modeling, a certain degree of difficulty exists in understanding the semantics of these notions in UML class diagrams. Some researchers claim class diagrams have limited use for conceptual analysis and that they are best used for logical design. Performing conceptual analysis should not concern the ways facts are grouped into structures. Whether a fact will end up in the design as an attribute is not a conceptual issue. UML leads to drilling down into physical design details (e.g., private/public attributes, encapsulated operations, and navigating direction of an association). This paper is a venture to further the understanding of object-orientated concepts as exemplified in UML with the aim of developing a broad comprehension of conceptual modeling fundamentals. Thinging machine (TM) modeling is a new modeling language employed in such an undertaking. TM modeling interlaces structure (components) and actionality where actions infiltrate the attributes as much as the classes. Although space limitations affect some aspects of the class diagram, the concluding assessment of this study reveals the class description is a kind of shorthand for a richer sematic TM construct.

Objectives: This study attempted to explore the aging phenomena that now characterize much of Korean society, and assessed issues associated with the life satisfaction experienced during the process of aging. Methods: By employing the National Survey on the State of Life and the Desire for Welfare of the Elderly, 2004 in South Korea this study attempted to identify the factors that determine subjective life satisfaction among the elderly. The data utilized herein consisted of 3278 elderly people aged 65 years or older, from 9308 households. Results: The results of analysis from the final model after the introduction of 19 variables in 8 factors showed statistically similar explanatory power in men (adj. $R^2=0.320$) and in women (adj. $R^2=0.346$). We found that economic condition was the most influential factor in both men (B = 0.278) and women (B = 0.336) except perceived health condition variables. The second most influential variable in life satisfaction was health checkups in men (B = 0.128) and degree of nutritional diet in women (B = 0.145). Those who had experience with chronic diseases also reported significantly lower perceived life satisfaction and this was particularly true of women. Conclusions: The aging society requires an understanding of the lives of elderly individuals. This study explored factors associated with life satisfaction in old age by using a life satisfaction model. The success of an aging society begins with an accurate understanding of the elderly, and thus political attention will need to be focused on this matter.

The purpose of this study was to explore what kinds of science communication are ongoing in formal and informal settings for learning about nuclear energy, which is very important issue domestically and internationally. The researchers collected and analyzed data from science textbooks at elementary and middle school levels, from exhibitions in Y informal hall that belongs to one nuclear power plant, and from 40 bestselling books about nuclear energy in order to explore the kind of science communication. The same process was used to explore Japanese case so that we could compare the results with Korean cases and draw implications for enhancing science communication about nuclear energy. The science communication of nuclear energy in Korea included implicit and indirect content espoused in science textbooks; two opposite views displayed in bestselling books, and positive aspects mainly displayed in exhibition of information hall in nuclear power plant. It is suggested that both direct and explicit science communication along with the neutral viewpoints including positive and negative ones be provided for the public to form a good understanding of nuclear energy.

The terminology used for oriental medicine has not yet been standardized so far and this might cause the problems in developing theories and clinical research of oriental medicine. To establish scientific backgroupd of oriental medicine, it is required that all the terminology used for oriental medicine should be standardized and unified. For more efficient oriental medical practice, the standardization, unification of the terms and conditions used for diagnosis in oriental medicine should be achieved. The aim of this study are as follows; 1. To provide clear and logical systems for the diagnosis of symptoms and diseases. 2. To provide the theoritical clearmess of oriental medicine and to promote the public facilities for study. 3. To provide ways of idea exchange and understanding between oriental medicine and various biological sciences. 4. To provide practical basis for hospital administration for oriental medicine.

Purpose: The purpose of this study was to describe the essential structure of the postmortem- examination experiences of nurse career coroners (forensic investigators), to have a profound understanding of their experiences, and ultimately to lay the foundation for nurses' entry into the field of forensic nursing. Methods: The subjects in this study were six coroners. After an in-depth interview from January to June 2007, the collected data were analyzed by Colaizzi as qualitative research. Results: Four categories emerged from seven theme clusters. The four categories were: attracted by being dubbed a stabilized public official, a sense of achievement due to having clarified false death, self-confidence after distinguishing the victim and the wrongdoer, eternal developmental potential is seen. Conclusion: It is expected that this study will provide useful information for nurses who are interested in becoming coroners. It will be helpful for career nurses to extend their nursing science into emerging fields like coroners and select a follow-up career.

This study recognizes that there is a correlation between the movement of the financial market and the sentimental changes of the public participating directly or indirectly in the market, and applies the relationship to investment strategies for stock market. The concerns that market participants have about the economy can be transformed to the search terms that internet users query on search engines, and search volume of a specific term over time can be understood as the economic trend of big data. Under the hypothesis that the time when the economic concerns start increasing precedes the decline in the stock market price and vice versa, this study proposes three investment strategies using casuality between price of domestic stock market and search volume from Naver trends, and verifies the hypothesis. The computational results illustrate the potential that combining extensive behavioral data sets offers for a better understanding of collective human behavior in domestic stock market.

Unlike conventional CT scan, the helical CT scan uses continuous rotating CT equipment with a slip ring to move the patient's coach at a constant speed while continuously scanning. Slice sensitivity profiles in the Z-position(SSPz) using the conventional X-ray CT have a shape similiar to a rectangular wave, which slightly spreads out into plains below the mountain. However, in the helical CT, with an expansion of the base, the rectangular shape collapses and a mouatain-like shape can be seen. We need to investigate the fellowing factors in helical CT scanning;the ability to scan along the axis of the body, effective slice width, slice shape and the precision of coach velocity, Helical scanning with sprial X-ray track is different from the conventional scanning in terms of the principle of image reconstruction performed. We believe that the problems in helical scanning can be solved by understanding new the special parameters such as the bed moving speed and the interval of image reconstruction.

이 논문은 아토피 질환에 대한 '한국적'인 이해와 대응을 낳은 역사적 과정을 살펴본다. 유전적 소인이 있는 특이면역성 질환 아토피는 외국의 경우에 '환경병'으로 인식되는 우가 드물다. 하지만 한국에서 아토피는 '환경호르몬' 등의 위험요소들과 결부되며 표적 환경병의 지위를 갖고 있다. 아토피에 대한 이러한 이해는 사전예방원칙과, 매체중심이 아닌 수용자중심의 환경오염 관리라는 전향적 원칙을 내세운 2008년의 환경보건법 탄생에 중요한 역할을 했다. 논문은 이 규제과정에 있어서 대중의 지식적 정치적 활동의 역할을 살펴본다. '아토피 = 환경병'으로 아토피를 이해하는 데 있어 가장 중요한 역할을 한 것은 아토피 아이들을 둔 아토피 엄마들이다. 이들은 의학과 독성학 등 과학계의 성과는 물론 본의 '아토피 아이, 지구의 아이'와 같은 환자조직의 활동경험과 성과를 이용, 대중적 호소력을 발휘한 '아토피 이론'을 제시했다. 이들은 과학적 불확실성을 전용하는 편, 한의학계, 생협, 민노당 등과도 지식 정치적 연대를 형성함으로써 환경보건법이라는 성과를 내게 된다. 이 논문은 이 과정을 검토함에 있어 '대중'이라는 주체가 성되어가는 역사성과 사회적 이슈 형성의 문화적 맥락에 관심을 돌린다. 이러한 연구는 위험규제나 정책연구 등에 역사적 역동성에 대한 논의의 단초를 만들 수 있다.
