This study dealt with approaches in architecture and music in the contemporary situation characterized by accidence and uncertainty through Pierre Boulez and Rem Koolhaas' works. First of all, we examined basic positions with starting from zero degree breaking from fixed ideas and with relative neutrality. Then, from a methodological aspect, we inquired into 1) anti-hierarchical objective approach, 2) accidental approach to form. 3) diagram of structure and event, and 4) the use of selective routes. Lastly, from a receptive aspect, we dealt with the space of pluralistic perspective and works in progress. The two persons used chaosmos approach that enables adjustment and control through structure defining the relationship with accidence or chaos. With the approach, they created works in progress or open works that have a pluralistic viewpoint working in the field of specific relation and the concept of endless regeneration.

In collaborative environment, it is necessary that the participants in collaboration should share the same understanding about the semantics of terms. For example, they should know that 'COMPONENT' and 'ITEM' are different word-expressions for the same meaning. In order to handle such problems in information sharing, an information system needs to automatically recognize that the terms have the same semantics. So we develop an algorithm mapping two terms based on their ontological definitions and their similarities. The proposed algorithm consists of four steps: the character matching, the inferencing, the definition comparing and the similarity checking. In the similarity checking step, we consider relation similarity and hierarchical similarity. The algorithm is very primitive, but it shows the possibility of semi-automatic mapping using ontology. In addition, we design a mapping procedure for a mapping system, called SOM (semantic ontology mapper).

The purpose of this study was to examine the relationships between career maturity, anxiety and school related adjustments levels of adolescents. A sample of 319 1th grade high school students in Seoul Metropolitan area participated in this study. The subjects completed questionnaires on the levels of school related adjustments, anxiety and career maturity. Data were analyzed by means of Pearson's correlation coefficients, as well as multiple and hierarchical regressions. Career maturity, as well as anxiety was founded to be a predictor to the school related adjustments levels of adolescents; significant interactional effects were found between career maturity and anxiety in terms of school related adjustments. These results indicate the need for possible interventions in relation to adolescents' anxiety levels and to improve the school related adjustments levels of adolescents.

The purpose of this study was to examine the relationships between temperament, social support and positive, as well as negative emotions of institutionalized children. The participants were 198 children aged from 10 to 13 years old. They were recruited from 20 childcare facilities in Seoul. Data were analyzed using Cronbach alphas, factor analyses, frequencies, percentiles, t-tests and hierarchical regression analyses. The major findings were as follows: 1) on average, girls showed higher emotionality in temperament compared to boys. Girls reported greater support of school teacher than boys. Boys experienced significantly higher positive emotions than girls, while girls reported significantly higher negative emotions than boys. 2) Positive emotions were influenced by the support of the institutionalized family as well as school teachers. Negative emotions were influenced by the support of the institutionalized family.

The purpose of this study was to examine the relationships between child-mother 'goodness-of-fit', mothers' empathy and parenting stress. A sample of 324 mothers of 5th graders in the Seoul Metropolitan area participated in this study. Mothers answered questionnaires on the levels of their parenting stress, empathy and child-mother 'goodness-of-fit'. Data were analyzed using Pearson's correlation coefficients, as well as multiple and hierarchical regressions. Child-mother 'goodness-of-fit', as well as mothers' empathy was a predictor for parenting stress; significant interaction effects were found between child-mother 'goodness-of-fit' and the mothers' empathy on parenting stress. These results indicate the need for possible intervention in relation to mothers' empathy levels and to reduce parenting stress.

The purpose of this study was to examine the effects of stress response on safety behavior and to explore moderating effect of safety climate between stress response and safety behavior. 224 workers were asked to respond to the questionnaires that measured various demographic variables, stress response, safety climates and safety behaviors. A hierarchical regression was conducted to identify variables that had significant relationships with safety behavior and to examine moderating effect of safety climate between stress response and safety behavior. Results indicated that the depression response significantly predicted safety behavior. It was found that the safety climate was also a significant predictor for safety behavior. In addition, safety climate had a moderating effect on the relation between depression and anger responses and safety behavior.

The concept of Level Of Detail (LOD) was introduced and has been used to enhance display performance and to carry out certain engineering analysis effectively. We would like to use an adequate complexity level for each geometric model depending on specific engineering needs and purposes. Solid modeling systems are widely used in industry, and are applied to advanced applications such as virtual assembly. In addition, as the demand to share these engineering tasks through networks is emerging, the problem of building a solid model of an appropriate resolution to a given application becomes a matter of great necessity. However, current researches are mostly focused on triangular mesh models and various operators to reduce the number of triangles. So we are working on the multi-resolution of the solid model itself, rather than that of the triangular mesh model. In this paper, we propose multi-resolution representation of B-rep model by reordering and converting design features into an enclosing volume and subtractive features.

The temporal structure of events on the discourse level has long been of great interest in both theoretical and computational linguistics. In this paper, we offer a unified approach to the temporal relationships related to a hierarchical discourse structure. We apply the method of pronoun resolution to the interpretation of tense. It is based on an analysis within the framework of the controlled information packaging theory. A unique aspect of our account is that temporal interpretation across discourse segments in global discourse is subject to the same principles as the interpretation of global anaphora, and that there is thus no need to postulate independent principles to account for the discourse behaviour of tense. In this way, we can neatly explain the general view that tense parallels the anaphoric nature of pronouns.

In this paper, we focus on the building domain ontology from corpus by extracting concepts and properties relationships based on linguistic patterns. The pharmacy field is selected as an experiment domain and we present an algorithm to extract hierarchical structure for terminology based on the noun/suffix patterns of terminology in domain texts. In order to show usefulness of our domain ontology, we compare a typical keyword based retrieval method with an ontology based retrieval mettled which uses related information in an ontology for a related feedback. As a result, our method shows the improvement of precision by 4.97% without losing recall.

This study was a cross-sectional reaserch that analyzed the factors that most affect COVID-19 knowledge in nursing college students who are relatively at high risk for recent prevalence of COVID-19 exposure in relation to clinical practice of nursing college students. A total of 249 nursing students participated in this study, 93 male students and 156 female students. The period for collecting data from structured questionnaires was from October 1 to October 20, 2021. The collected data were frequency analysis, Pearson correlation analysis, simple regression analysis, and hierarchical regression analysis using SPSS 18.0. As a result of the analysis, infection prevention behavior(𝛽=0.06, p=0.006) had the most influence on COVID-19 knowledge, and the second was professional intuition(𝛽=-.162, p=0.018). Based on the results of this study, in order to improve the knowledge of COVID-19 among nursing students, it is proposed to develop an infection prevention behavior education program and a professional intuition improvement program.
