  • Crimes must be reduced not only because of the financial, physical, and emotional damages they bring to the victims but also because crimes increase social costs by elevating distrust in society and instilling fear. With the increasing number of crimes in Korea, finding other factors that affect the occurrence of crimes is needed beyond the current viewpoint for crime analysis. Social support factors can be candidates for studies on the social support effect on crime occurrence in their initial stage. In this study, we identified the effect of social support factors on crime occurrence or deterrence, none of which has been considered important until now, given the emergence of spatial econometrics. The resulting Moran's I values revealed the existence of a spatial autocorrelation in all three crimes: heinous crimes, theft, and violence. As shown in the analysis using spatial econometrics and ordinary least squares, social support from families is significant in reducing all crimes especially violence. Social support from the local government is significant in preventing only theft. The spatial econometrics model is only valid in heinous crimes. These different effects of social support factors and spatial factors on crime occurrences are caused by the different characteristics of crimes. Hence, policymakers should consider the social support effect when they establish policies related to social housing or welfare.

  • This paper is related to color image segmentation and textile texture mapping for the 2D virtual wearing system. The proposed system is characterized as virtually wearing a new textile pattern selected by user to the clothing shape section, based on its intensity difference map, segmented from a 2D clothes model image using color image segmentation technique. Regardless of color or intensity of model clothes, the proposed system is possible to virtually change the textile pattern or color with holding the illumination and shading properties of the selected clothing shape section, and also to quickly and easily simulate, compare, and select multiple textile pattern combinations for individual styles or entire outfits. The proposed system can provide higher practicality and easy-to-use interface, as it makes real-time processing possible in various digital environment, and creates comparatively natural and realistic virtual wearing styles, and also makes semi-automatic processing possible to reduce the manual works to a minimum. According to the proposed system, it can motivate the creative activity of the designers with simulation results on the effect of textile pattern design on the appearance of clothes without manufacturing physical clothes and, as it can help the purchasers for decision-making with them, promote B2B or B2C e-commerce.

  • The particle based computational fluid dynamics (CFD) method, which follow Lagrangian approach for fluid dynamics, fluid particle behavior by tracking all particle calculation physical quantities of each particle. According to basic concept of particle based CFD method, it is difficult to satisfy continuum theory and measure influences from neighboring particle. Article number density and weight function were used to solve aforementioned issue. Difficulties continuum mean simulate non-continuum particles such as solid including granular and sand. In this regard, the particle based CFD method modified solid particle problems by replacing viscous and surface tension forces friction and drag forces. In this paper, particle interaction model for solid particle friction model implemented to simulate solid particle problems. The broken dam problem, which is common to verify particle based CFD method, used fluid or solid particles. The angle of repose was observed in the simulation results the solid particle not fluid particle.

  • Since the 20th century, it was often announced that a painting was dead, but it is still alive. Even in the epoch of recently increasing virtuality, painting is still appealing, consistently pursed by many with a thirst. Thus, it is said that the mission of a picture is to maintain its reality without being trapped in virtuality. In the history of Western painting spanning over several hundreds of years the myriad of techniques and styles have emerged, going though a huge variety of changes: namely, its not possible any longer to find the new ways of expression in painting. Hence, painters today feel that it becomes more gradually difficult for them to execute something. In the midst of swiftly changing, diversely evolving trends of contemporary art, the painters incessantly pose a question why they go on working on painting, and seek to find its answer. Why the painters still try to say something about painting? Is that because they consider it the quintessence of fine arts or think that it is in no way possible or meaningful to comment on fine arts without relying on painting? If then, is there any avenue of escape for the painting? The question of the 'crisis of painting' is still raised, when reviewing the rapidly changing conditions of inventing artworks. That is also why the recent works failed to offer a conceptually unified, universally shared perspective of painting. Moreover, painting is left to shrink comparatively with the pervasive existence of videos and installations briskly employing digital images and technologies in their creations. Whats more problematic is the fact that there is a growing sense of crisis not only in the sphere of painting hut also in the entire realm of art. As the organizers and curators of big-scale exhibitions and art projects tend to exploit their space spectacularly, focusing primarily on their abilities to control the space, there is a pervasive notion amongst them that painting is a medium that is not properly to suit such purposes and requests. Today, the death of painting is, in fact, the death of modernist painting, which assumed a central role in the history of art for a considerable amount of time, rather than the death of painting itself. Employing a new paradigm of invention, a picture is now entering a new domain which is perhaps unknown to us. Moving beyond the stereotypical concepts of painting, physical property and flatness, pictures today reveal the introduction of time and space and the penetration of new media such as installation, photography, video and the Internet. Despite such trends, the dexterity and tactile capability of painters is still to be considered significant in the future. The renewal of painting is made in an entirely unexpected manner and place.

  • Many objects existing on wide area environments have the replication characteristics according to how to categorize using their own names or properties. From the clients' requests, the existing naming and trading services have not supported with the binding service for replicated solver object with the same service type. For this reason, we present an integrated model that can support the selection of replicated object and dynamic binding services on wide-area computing environments. This model suggests provides not only location management of replicated objects but also active binding service which enables to select a least-loaded object on the system to keep the balance of load between systems. In this purpose, constructing both the service plan and model for support solver object's binding with replication property on wide area computing environments has been researched. In this paper, we showed the test environment and analyzed the performance evaluation of client/server binding procedures via integrated binding service in federation model and verified our model under the condition to see whether load balance can be applied to our model. For the performance evaluation of suggested wide area integrated binding service federation model, evaluated the integrated binding service of each domain and analyzed the performance evaluation of process for non-replication object's under federation model environment. Also, we analyzed the performance evaluation of the federation model between domains for wide area environment. From the execution results, we showed the federation model provides lowers search-cost on the physical tree structure of network.

  • This historical research was conducted to analyze and categorize the titles which were presented in the journal, The Korean Nurse, from August 1962 to October 1995. Titles which were published with the purpose of educating graduate nurses and to update 0 their nursing knowledge to improve professional practice were included. There were 348 articles published from the beginning of publication in August, 1962 to October, 1995. All of the journals were reviewed except nine missing journals which were not available in any library. According to the characteristics of the articles in the periodical, the articles were divided into three periods. In each of the three peroids there were five categories: Subject, Clinical Practice, Fundamentals of Nursing Science, Nursing Administration, Others. These categories were adopted from Kim's(1994) division system which was developed to analyze nurse's insurance education program. The special feature peroid was from August, 1962 to December, 1974. In this period the articles were presented in an unorganized manner in the area of special feature or main issue. The largest area was the subject category(44%). The second largest area wes the fundamental of nursing science category(31%). From May, 1975 to December, 1977, the articles with the educational purposes were published in a designated area called continuing education. This period was labelled as the continuing education period. Among the published articles in this period, 45% focused on the subject category and 45% on the fundamentals of nursing science category. In this period the articles were focusing on nurses 'work in specific areas such as industry, nurses' aid schools, and nursing administration, articles on physical assessment first started to appear. The written continuing education period was from January 1978 to October, 1995. All the educational articles published in this area were analyzed and categorized into five areas as for the other periods. 48% of the articles focused on the subject category. In the mid-eighties, the term nurse specialist first.appeared and ten years later in 1990, the titles were subdivided into more specific titles, such as, home nursing, industrial nursing, emergency nursing, 23% were in the fundamental nursing science category and they dealt with nursing process, nursing theories, theory development. For the content analysis, three articles, one from each period, dealing with cardiovscular diseases were selected for comparsion. First, the special feature period, the title of the article was on diet therapy for cardiovascular disease patients, but instead the content was about rest, hygiene, medication, observation. They recommended rings to prevent bed sores, which is now considered as a cause for bed sores. In the continuing education period, the content was more focused on rehabilitation rather than general nursing .care. It became more specific, systematic, and organized compared with the special feature period. In the written continuing education period, the focus was on rehabilitation, not broadly, but very specifically on exercise. The further research on the content analysis is recommended along with a comparison of the trends in the Journal of Nurses Academic Society.

  • Current neuroscience views the mind-body problem from the monistic perspective which claims that the human mind is the result of brain activity and that the mind shuts down when the brain does. However, a considerable number of lay people still believe in the existence of the soul and the afterlife, concepts that are hard to explain from the monistic perspective. This study examines whether lay people think that the mind of the dead is capable of exceeding the physical constraints if they believe that such mind exists. After reading one of three vignettes which describes the state of the protagonist as alive, dead, or brain dead, the participants evaluated the protagonist's general mental capacity and transcendental ability to obtain new information. The participants rated that the dead protagonist had more 'transcendental ability to obtain new information' than the alive one if they evaluated high general mental capacity to the protagonist. In addition, unlike the alive condition, in the dead and the brain dead condition, there was a correlation between the general mind capacity rating and the transcendental ability rating. The results suggest that lay people expect the mind of the alive and the dead to be different, as they believe the latter's general mind capacity connotes transcendental ability. We also found that the participants' religiosity affected their beliefs about the transcendental ability of dead person.

  • Light shows various optical behaviors such as reflection, absorption, and scattering on skin for individuals. In particular, reflection of light from the skin has been widely used as the brightness index of the skin of individuals through the measurement of the physical quantity of spectral reflectance. Therefore, the study of light behavior on skin would be useful for the preparation of new evaluation method in the development stage of make-up products. In this study, multi-dimensional analysis for spectral reflectance behavior of light on individual skin was performed using Kubelka-Munk model. Also, we analyzed the contribution of skin parameters such as skin thickness and hemoglobin, which could affect the spectral reflectance, using above model and literature information. Base on this, we calculated the theoretical reflectance of normal women for visual light, which showed good agreement with the measured reflectance. Our study of light propagation in skin based on Kubelka-Munk model provides useful insight for the development of personalized cosmetic in the near future.

  • Nurses experience role conflict between nursing theory that they learned in school and clinical nursing practice. This conflict lead to lower self-image, self-esteem, job dissatisfaction. Also, the professionalism of nurses is estimatable by the grade of autonomy. The professional autonomy requires individual and professional obligation about her decision and performance. A lack of professional autonomy results in the Job dissatisfaction. Job dissatisfaction leads to absenteeism, increased proneness to mental and physical illness and higher turnover rates. The purpose of this study was to investigate professional autonomy and self-concept of clinical nurses. Data were collected from 262 clinical nurses in P city from June 1 to June 30, 1996. The instruments used for this study were made by Arthur(1990) and Schutzenhofer(1983). The data were analyzed for frequency and percetage, mean, SD, t-test, ANOVA, Pearson's correlation coefficient, stepwise mutiple regression, using SAS $PC^+$ Program. The findings were as it follows : 1. The mean of professional autonomy and self-concept were $152{\pm}18.48,\;70.65{\pm}8.20$(2.62), respectively. These showed mid level of professional autonomy and self-concept. 2. Professional autonomy of clinical nurses was found to vary significantly according to total years of clinical experience(F=4.49 p<0.01), position(F=3.49 p<0.05), and state under study for the degree(F=3.83 p<0.05). Professional self-concept was found to vary significantly according to age(F=3.52 p<0.05), marital status(F=7.39 p<0.001), total years of clinical experience(F=3.59 p<0.05), position(F= 5.22 p<0.01), the expectant period being on the duty as clinical nurse(F=8.34 p<0.001), and motivation of choosing nursing(F=5.17 p<0.001). 3. The statistical relationship between clinical nurses' professional autonomy and self-concept was found as positive correlation(r=0.42246 p<0.001). 4. Professional autonomy was the highest factor predicting professional self-concept(17.85%). Professional autonomy and marital status accounted for 20.60% in professional self-concept of clinical nurses. In conclusion, Professional autonomy and self-concept of clinical nurses showed significantly positive relationship. Therefore, nursing education needs to develop programs and policies to increase professional autonomy and self-concept of clinical nurses.
