Among the discussions on affective representation, the first is to explain the affective representation in the dimensions, and the second is to explain the affective representation according to the modality. In previous studies, to explain affective representation, valence models (signed valence, unsigned valence) and Modality-generality models (modality-general, modality-specific) were presented. In this study, we compared models presented in the previous study using the recently published ASMR to confirm which models explain affective representation well. The data used in this study were behavioral rating values collected by Kim & Kim (2022), and these were obtained for ASMR stimuli that were divided into three affective types (negative, neutral, and positive) and two modalities (auditory and audiovisual). Then, a multidimensional scaling, a representational similarity analysis with a two-way repeated measures ANOVA, and a multiple regression analysis with a two-way repeated measures ANOVA were performed. The results revealed that signed valence and modality-general distinguished between affective types of stimuli better than unsigned valence and modality-specific. Similar to the results of multidimensional scaling, the results of a representational similarity analysis and a multiple regression also showed that the signed valence and modality-general significantly explained affective representation better than the unsigned valence and the modality-specific. These results suggest that the model in which positive and negative are located at the opposite ends of the one dimension explains the affective representation of ASMR well, and that the affective representation was consistent regardless of modality.

In the present work, we investigate the hydrodynamic behavior of a turbulent bore, such as tsunami bore and tidal bore, generated by the removal of a gate with water impounded on one side. The bore generation system is similar to that used in a general dam-break problem. In order to the numerical simulation of the formation and propagation of a bore, we consider the incompressible flows of two immiscible fluids, liquid and gas, governed by the Navier-Stokes equations. The interface tracking between two fluids is achieved by the volume-of-fluid (VOF) technique and the M-type cubic interpolated propagation (MCIP) scheme is used to solve the Navier-Stokes equations. The MCIP method is a low diffusive and stable scheme and is generally extended the original one-dimensional CIP to higher dimensions, using a fractional step technique. Further, large eddy simulation (LES) closure scheme, a cost-effective approach to turbulence simulation, is used to predict the evolution of quantities associated with turbulence. In order to verify the applicability of the developed numerical model to the bore simulation, laboratory experiments are performed in a wave tank. Comparisons are made between the numerical results by the present model and the experimental data and good agreement is achieved.

Man-made structure materials like concrete usually contain inclusions. These inclusions affect the mechanical properties of concrete. In this investigation, the influence of inclusion length and inclination angle on three-dimensional failure mechanism of concrete under uniaxial compression were performed using experimental test and numerical simulation. Approach of acoustic emission were jointly used to analyze the damage and fracture process. Besides, by combining the stress-strain behavior, quantitative determination of the thresholds of crack stress were done. concrete specimens with dimensions of 120 mm × 150 mm × 100 mm were provided. One and two holes filled by gypsum are incorporated in concrete samples. To build the inclusion, firstly cylinder steel tube was pre-inserting into the concrete and removing them after the initial hardening of the specimen. Secondly, the gypsum was poured into the holes. Tensile strengths of concrete and gypsum were 2.45 MPa and 1.5 MPa, respectively. The angle bertween inclusions and axial loadind ary from 0 to 90 with increases of 30. The length of inclusion vary from 25 mm to 100 mm with increases of 25 mm. Diameter of the hole was 20 mm. Entirely 20 various models were examined under uniaxial test. Simultaneous with experimental tests, numerical simulation (Particle flow code in two dimension) were carried out on the numerical models containing the inclusions. The numerical model were calibrated firstly by experimental outputs and then failure behavior of models containing inclusions have been investigated. The angle bertween inclusions and axial loadind vary from 0 to 90 with increases of 15. The length of inclusion vary from 25 mm to 100 mm with increases of 25 mm. Entirely 32 various models were examined under uniaxial test. Loading rate was 0.05 mm/sec. The results indicated that when inclusion has occupied 100% of sample thickness, two tensile cracks originated from boundaries of sample and spread parallel to the loading direction until being integrated together. When inclusion has occupied 75% of sample thickness, four tensile cracks originated from boundaries of sample and spread parallel to the loading direction until being integrated together. When inclusions have occupied 50% and 25% of sample thickness, four tensile cracks originated from boundaries of sample and spread parallel to the loading direction until being integrated together. Also the inclusion was failed by one tensile crack. The compressive strength of samples decease with the decreases of the inclusions length, and inclusion angle had some effects on that. Failure of concrete is mostly due to the tensile crack. The behavior of crack, was affected by the inclusion length and inclusion number.

During the past two decades or so, science (or scientific or scientific & technological) culture has become one of the main themes not only of policy makers but also of science educators. Although, the idea of science culture has been taken as a desirable goal, there is little agreement about what it means and how to measure it. Particularly in Korea, there has been a rapid growth of science culture projects and programs, either by governmental or non-governmental, but with little systemic monitoring and evaluation for its practice. The purpose of this study is, thus, to explore a model of measuring science culture and develop a comprehensive indicator system for it. We reviewed many literatures on definitions of science culture and the surveys for related terms, particularly, of recent national and international surveys (e.g. US Science and Engineering Indicators, Eurobarometer, Japanese Science and Technology Indicators). Based on this review, a model for science culture is proposed and then used to define the Science Culture Indicators (SCI). This model encompasses two dimensions(i.e. individual and social), which are further divided into two aspects (i.e. potential and practice). Each dimension is expected to represent citizen literacy of and national infrastructure of science culture respectively. Each category in this $2{\times}2$ matrix is further divided into several sub-categories. The discussion concerning how the model and the indicators can be used to check the states of science culture at social as well as individual levels will be given with some concrete examples, such as indicators particularly related to science education.
It has been a major agenda in criticism that there have been a dominant tendency of male-centered narratives in Korean mainstream films after . These kinds of narratives could be accept as a result of searching process in virtual realm for understanding the social changes. I suggest $H.Lef\acute{e}bvre's$ very familiar concept 'quotidienne', which influences the conditions to constitute male-identity as a fundamental base of male-centered narratives, to analyze and . It seems meaningful these texts tried to reconstitute male-identity through distinguish potential energy of 'quotidienne' from repressive everyday-life. The result of analysis has lied two ambivalent dimensions, nevertheless, it would be required further studies to argue on male-centered narratives and discourses of male-identity as which results could represent interactions between various social contradictions.

This study aims to analyze the spatial distribution pattern of international trade. The method is to analyze the principal components by changing interaction attribute matrix of four dimensions (hinterland, gateway, foreland and commodities) into two dimension matrix. The study area is the territory region of Cheongju clearance depot in inland. The result are as follows : Major spatial patterns of regional connections by hinterland, gateway and foreland are, in the case of exports, ten patterns and in the case of imports come to nine. Composition of major export and import commodities in Cheongju clearance depot are similar, but precision instrument manufactured commodity and nonmetal mineral are remarkable in export and mineral manufactured commodity machinery and electronic manufactured commodity are remarkable in import. Gateway are similar to export and import, but Incheon international airport is used more in the case of import. And Cheongiu international airport is used for some commodities and is remarkable as a foreland of import for the areas outside of Chungcheongbuk-do.

The existing cadastral record cannot meet various and changing demands on land information, improve user convenience, and raise administrative efficiency. In addition, three-dimensional parcels, or spatial objects about three-dimensional space cannot be registered in the conventional cadastral record. The limitation of cadastral information based on two dimensions is quite stressing the necessity of three-dimensional cadastral record. The purpose of this study is to develop new limns of cadastral record model in order. In register three-dimensional positions and right relations of land and buildings. This study examined land cases where space was being three-dimensionally used. As the result, cadastral record models both separated by steps and integrated were developed, which can contain matters of land, buildings, and right registration about three-dimensional land parcels. Also, this study suggested a method where a building can be separately registered according to it's the superficies division.
Objectives: In Korea, the percentage of elderly is increasing at an unprecedented rate, and is expected to account for 40% of the population by 2060. This massive demographic change stresses the importance of research on aging as it is necessary to improve the quality of life (QoL) of this population. This study aimed to examine the health-related quality of life (HRQoL) of the rural elderly and to clarify its association with the nutrient adequacy ratio (NAR). Methods: A cross-sectional study was performed in S-gun, Chonbuk, a critical agricultural area. The elderly people without abnormal physical functioning composed our study population and the data were collected by personal visits to 336 elderly people aged over 65 years (110 males and 226 females). Subjects were interviewed with questionnaires pertaining to general characteristics and EuroQol (EQ-5D). Nutrient intakes were assessed two days by 24-hours recall method. Subjects were defined as high QOL group if EQ-5D index with Nam's model was above the median. Results: Generally, EQ-5D index was lower in women than in man, and lower in older subjects than in younger subjects. The percentages of people below the median were 42% (low QoL group) and 58% (high QoL group) were found to be the above the median. The high QoL group had higher NAR, especially for vitamin C, vitamin B1, vitamin B2 and folate. All dimensions in the EQ-5D were affected by NAR of some nutrients and especially anxiety/depression dimension was significantly correlated with NAR of 5 nutrients (protein, calcium, iron, vitamin C and vitamin B1) and EQ-5D scores. Conclusions: HRQol was significantly reduced in elderly with increasing age and this was more pronounced in women than in man. The NAR of some nutrients were associated with the EQ-5D index, especially anxiety/depression dimension, among rural elderly.
The purpose of this study was to investigate the social exclusion of 'Da-Ka-Gu' rental housing and permanent rental apartments and to provide basic source of their socio-demographic characteristics and actual conditions of social exclusion. Self-administered questionnaires and interviews were carried out with 212 dwellers in 'Da-Ka-Gu' rental housing and permanent rental apartments in the city of Gwangju from July to October of 2010. The main findings are: 1. The social exclusion of physical deficiency dimension composed of income and employment has been found to be the most serious level, compared to all the other dimensions. 2. The social exclusion from health has been found to be the highest level in the dimension of the approach to social rights. The next highest level has been found to be the social exclusions from residential areas and education and service areas. 3. The level of social exclusions from the areas of family relations and social relations, which are in the dimension of social participation, has been found to be next highest to the level of physical deficiency dimension. 4. The level of exclusion from cultural and normative integration has not been found to be of significant difference between the two types of residence in this study. This study of the actual conditions of social exclusion among residents living in 'Da-Ka-Gu' rental housing and permanent rental apartments suggests the necessity and some practical implications for policy measures of social integration for the residents of lowincome housing.
Organizing and maintaining customer-based online communities are becoming increasingly important in current business environment. Companies can utilize the member generated contents in developing their products and services and they can establish close relationships with their customers. This paper investigates how customer-based online communities increase individual members' contributive behaviors. Drawing on the social psychology literature, this study adopts the concept of self-discrepancy rooted in self-identity and derive an index for self-discrepancy by using the differences between actual and virtual self-identities. Furthermore, this study examines the relationship between the self-discrepancy and the anonymity-related psychological factors (autonomy, recovery, and catharsis), which in turn influence quality and quantity of contribution. Analysis of 114 respondents showed that self-discrepancy between actual and virtual selves has two different sub-dimensions (personal self-discrepancy and social sel f-discrepancy) and each dimension has different effect on the quality and quantity of contribution through the mediation of autonomy and recovery. Notably, catharsis negatively influenced quality of contribution. Theoretical and practical implications are discussed based on the major findings.
