A simulation-based approach is proposed to study the protective actions taken by residents during nuclear emergencies using cognitive findings. Human perception-based behaviors are not heavily incorporated in the evacuation study for nuclear emergencies despite their known importance. This study proposes a generic framework of perception-based behavior simulation, in accordance with the ecological concept of affordance theory and a formal representation of affordance-based finite state automata. Based on the generic framework, a simulation model is developed to allow an evacuee to perceive available actions and execute one of them according to Newton's laws of motion. The case of a shadow evacuation under nuclear emergency is utilized to demonstrate the applicability of the proposed framework. The illustrated planning algorithm enables residents to compute not only prior knowledge of the environmental map, but also the perception of dynamic surroundings, using widely observed heuristics. The simulation results show that the temporal and spatial dynamics of the evacuation behaviors can be analyzed based on individual perception of circumstances, while utilizing the findings in cognitive science under unavoidable data restriction of nuclear emergencies. The perception-based analysis of the proposed framework is expected to enhance nuclear safety technology by complementing macroscopic analyses for advanced protective measures.

Australian Curriculum Assessment and Reporting Authority(ACARA) was founded by Australian federal government in 2009. Leading under ACARA, national education curriculum development was propelled. Also from 2014 they gradually extended enforcement of new curriculum by a Reminder about new syllabus implementation (2013.01.29.). The research result of Australia's curriculum, and textbook shows that students repeat, and advance the same contents under spiral curriculum as they move to higher grade. They actively use digital technology, and also puts emphasis on practical context such as Money & financial mathematics. On the level of difficulty, or quantity aspect, Korea handles relatively advanced contents of 'number and operation' or 'Letters and Algebraic Expressions' domain than Australia. However on statistics domain, Australia not only puts more focus on practical stats than Korea, but also concerns as much on both various and qualitative terms Australia doesn't deal with formal concept of 'function'. However, they learn the wide concept of function by handling various graphs. This shows Australia has a point of similarity, and also difference to Korea on various angles.

This study is to investigate the level and connection of learning concepts related to metabolism presented in life science textbooks developed according to the national common basic curriculum. One kind of elementary school, and three kinds of middle school and high school science textbooks were analysed. The gross number of concepts related to metabolism was 42 in elementary, 149 in middle and 126 in high school science textbooks. The number of concepts was much more different by school than by publisher. Ratio of the number of concrete versus formal concepts decreased gradationally by grade, but the number of learning concepts increased radically by grade. Thus, it is implied that science learning concepts are presented considering the number of concepts as well as cognitive level of learner, and unit and content are constructed on the connection among them in developing science curriculum and textbooks.

The purpose of this study is to mate a basic foundation for the discourse of Koreanness of contemporary Korean landscape architecture by way of searching the conceptual definitions of Koreanness through analysis of Koreanness discourses. The results are that discourses of Koreanness are to be classified in aesthetics type, spatial-temporal type, and cultural type. Aesthetics type is understood as style in terms of formal and design representation planning principles of spatial composition and immanence in terms of philosophy. Spatial-temporal type is understood as contemporaneity. This is classified as the concept of connoting of tradition, and separating and keeping a distance from tradition. Cultural type is prescribed as cultural identity. This is classified as unity, generality and individuality. The intension of Koreanness of these types is represented as an aspect changing and shifting from one regulation to another regulation. First, in the concerns of substantial archetypes like Korean original form, decorative element, spatial composition aesthetic perception and philosophy, Koreanness shifts to the point of view of contemporaniety which is created and defined in history. Second, Koreanness as contemporaniety shows a trend of shifting the point of view which is to be found through the reconsideration on modem history and modernism. Third, Koreanness defined as cultural identity shows a trend to emphasize the differences in other cultures and includes all the modem cultural agents. The number of views understood as individuality and denial are small but provide important points. Programmatic definition of Koreanness is not suitable. This basic study uses a stipulative or operational definition of Koreanness in many ways such as spatial and regional identity. Koreanness study for Korean contemporary landscape architecture requires a systematic understanding of modernity and colonization relating to identity. Also, it is needed to elaborate on the discourse to divide the meaning of a concept of identity.

As the use of digital systems becomes more prevalent, adequate techniques for software specification and analysis have become increasingly important in nuclear power plant (NPP) safety-critical systems. Additionally, the importance of software verification and validation (V&V) based on adequate specification has received greater emphasis in view of improving software quality. For thorough V&V of safety-critical systems, V&V should be performed throughout the software lifecycle. However, systematic V&V is difficult as it involves many manual-oriented tasks. Tool support is needed in order to more conveniently perform software V&V. In response, we developed four kinds of computer aided software engineering (CASE) tools to support system specification for a formal-based analysis according to the software lifecycle. In this work, we achieved optimized integration of each tool. The toolset, NuSEE, is an integrated environment for software specification and V&V for PLC based safety-critical systems. In accordance with the software lifecycle, NuSEE consists of NuSISRT for the concept phase, NuSRS for the requirements phase, NuSDS for the design phase and NuSCM for configuration management. It is believed that after further development our integrated environment will be a unique and promising software specification and analysis toolset that will support the entire software lifecycle for the development of PLC based NPP safety-critical systems.

This paper analyzes the religious circuit of suicidal concept based on verbal expression and ritual acts, which are found in the suicide discourse of Korean Catholic Church and Protestant Church. In the relationship of suicide and religion, it is easily overlooked the religious circuit and its construction that forms the concept of suicide among the religious laymen. It is assumed that the belief system of traditional religions prohibits suicide and the laymen accordingly construct a perception or concept of suicide along with this belief system. Various studies on this subject have proved it. However, in order to understand the religious way of constructing the concept of suicide on a personal level, it is necessary to pay attention to the religious environment in which the concepts and emotions of suicide circulate. The laymen do not passively and perfectly accept the finely established suicide concept provided by the doctrine or the theology. Rather, the laymen tend to collect the pieces of concept over the suicide that are drifting in the religious environment of his/her daily routine life and to make an concept of suicide in an incomplete form. We can find the unstable and imperfect traits of such a suicide concept through the experience of suicide survivors who have a religious background. For the suicide survivors with religious beliefs, they resist the formal doctrinal and theological provisions to suicide, or try to understand the notion of suicide in their own contexts. In terms of linguistic expressions and ritual acts relating to suicide, the attentions are differently directed in the public and the private domain among the religious groups. Considering on the high rates of suicide in Korean society, the Korean Catholic Churches are increasingly tolerant over the suicide and accept it in the public sphere. It is unlikely when comparing to the negative attitudes of the suicide in the past. However, such tolerance does not go beyond the doctrinal and ethical judgment that defines suicide as a serious sin. The once-committed lay believer's speech and gestures usually contain the various emotions, such as sadness, grief, anxiety, regretfulness, eagerness, and pain in the private spheres. The language and gestures with these emotions have been activated in the religious circuits of suicide, being extended to the religious apparatus for the person who died of suicide. In case of Protestantism, the institutional organizations, such as the particular denominations and the individual-churchism of the Korean Protestant Churches, and their own interpretations of the Bible have in the private sphere strongly effected on the linguistic expressions and the rituals related to the suicide. The religious-ethical judgment of the suicide is varied how the suicide is interpreted by the theologians and the pastors. And the ritual acts for healing the complex feelings and the psychological wounds of the suicide survivors are not actively explored and adopted yet. It makes harder to approach and heal the protestant followers since they emphasize the innermost belief and the salvation assurance faith.

The purpose of this study was to build a substantive theory about the experience of the maternal uncertainty in childhood chronic illness. The qualitative research method used was grounded theory. The interviewees were 12 mothers who have cared for a child who had chronic illness. The data were collected through in-depth interviews with audiotape recording done by the investigator over a period of nine months. The data were analyzed simutaneously by a constant comparative method in which new data were continuously coded into categories and properties according to Strauss and Corbin's methodology. The 34 concepts were identified as a result of analyzing the grounded data. Ten categories emerged from the analysis. The categories were lack of clarity, unpredictability, unfamiliarity, negative change, anxiety, devotion normalization and burn-out. Causal conditions included : lack of clarity, unpredictability, unfamiliarity and change ; central phenomena : anxiety, being perplexed ; context. seriousness of illness, support ; intervening condition : belief action/interaction strategies devotion, overprotection ; consequences : normalization, burn-out. These categories were synthesized into the core concept-anxiety. The process of experiencing uncertainty was 1) Entering the world of uncertainty, 2) Struggling in the tunnel of uncertainty, 3) Reconstruction of the situation of uncertainty. Four hypotheses were derived from the analysis : (1) The higher the lack of clarity, unpredictability, unfamiliaity, change, the higher the level of uncertainty (2) The more serious the illness and the less the support, the higher the level of uncertainty. (3) The positive believes will influence the devoted care and normalization of the family life. Through this substantive theory, pediatric nurses can understand the process of experiencing maternal uncertainty in childhood chronic illness. Further research to build substantive theories to explain other uncertainties may contribute to a formal theory of how normalization is achieved in the family with chronically ill child.

The purpose of this study was to classify male consumer groups according to the fashion lifestyle, to examine characteristics, needs and wants of each group, and to find out differences of cosmetics purchasing behavior among each group segment. After surveying 19-50 year old males by making a visit to college, company and home, 584 samples were analyzed by using SPSS(7.0) package program. Factor analysis, cluster analysis, ANOVA, crosstabs and $X^2-test$ were used to analyse collected data. The results of this study were as follows; 1. Twenty-two questionnaires using AIO fashion lifestyle variables produced seven factors; oriented fashion, flaunting brand preference, active preference, information intention, strong personality, reasonable economy and others directivity. Three groups based on oriented seven factors: personality, fashion and economy. 2. The Personality group had strong personal characters in their fashion. Men in this group prefer casual style and were represented by singles and professionals in their 30's. The fashion group pursued fashion trends, formal wears, and high-priced fashions. They were represented by singles with high-income managerial positions in their 19-29 age group. The economy group represented the largest sample in this study(54.5%). Men in this group tended to purchase fashion goods during of good fabrics at discount stores. This group represented married man with average incomes in their 40's. 3. Each of these three groups showed significant differences in cosmetics purchasing behavior. The personality group mainly purchased cosmetics on-line market because of price. The Internet tended to be their primary source of informations. They spent under 10,000won and pursued a simple and clear image. The fashion group purchased cosmetics at department stores to benefit from the knowledge of sales personal and their source of informations in the mass media. They spent over 70,000won monthly and pursued also a simple and clear image. The economy group purchased cosmetics at discount stores because of their wide assortment of products. They spent under 30,000won monthly and pursued a simple and clear image. Each of these groups currently consume different products and have a different concept of future cosmetic products.

This study was conducted to analyze the relationships between terms, learning concepts and inquiries in ocean unit, the National Common Basic Curriculum. The several science textbooks were selected to use for study, written in accordance with the 7 current national curriculum for the fourth grade of elementary school, the seventh of middle school and the tenth of high school. The higher the school level becomes, the frequencies of using terms related with ocean region get. The explanation of terms, however, has a tendency to be less frequent in the high school level. In the perspective of learning concept, there are more concrete concepts than formal concepts regardless of school level. Pure scientific context appears most often in inquiry contest through the whole course of every school level. In respect to inquiry process, the frequency of integrative inquiry process is on the increase as the school level gets higher. From the viewpoint of inquiry activity, there have been a lot of discussions, experiments and investigations in every school level, while high school does not the present any field study and project. Through these result, it is considered that the explanation of main terms is inevitable in the textbooks as basic educational material without regard to school level. In learning concept and inquiry context, a well-rounded learning is needed in relation to students' cognitive development and science-technology-society. Especially for the inquiry activity of earth science education, the educational effect is remarkable through field study; its appropriate application is required, accordingly.
