  • Even though a dual lens stereoscopic camera allows for convenient stereoscopic photography, the necessity for the research comes up, since the dual lens stereoscopic camera can cause visual discomfort during zoom-in due to the fixed convergence point. We propose a method based on which a convergence point can be adjusted to prevent visual discomfort during zoom-in for a dual lens stereoscopic camera. First, the relational model is classified into nine kinds and defined, depending on locations of focus, object, and convergence point. And then, the method to minimize visual discomfort is suggested by adjusting convergence point on the given model. We also implement the suggested methods with anaglyph computer graphic and demonstrate the superiority of them.

  • Today's commercial high resolution satellite imagery such as that provided by IKONOS and QuickBird, offers the potential to extract useful spatial information for geographical database construction and GIS applications. Digital maps supply the most generally used GIS data probiding topography, road, and building information. Currently, the building information provided by digital maps is incompletely constructed for GIS applications due to planar position error and warped shape. We focus on extracting of the accurate building information including position, shape, and height to update the building information of the digital maps and GIS database. In this paper, we propose a new method of 3D building information extraction with a single high resolution satellite image and digital map. Co-registration between the QuickBird image and the 1:1,000 digital maps was carried out automatically using the RPC adjustment model and the building layer of the digital map was projected onto the image. The building roof boundaries were detected using the building layer from the digital map based on the satellite azimuth. The building shape could be modified using a snake algorithm. Then we measured the building height and traced the building bottom automatically using triangular vector structure (TVS) hypothesis. In order to evaluate the proposed method, we estimated accuracy of the extracted building information using LiDAR DSM.

  • This study aims to explore the creation of fashion design that embraces the diversity of human culture by examining oriental images that appear in the modern fashion with a focus on new paradigms that significantly affect human life as the latest trends, and by reflecting the trends of the times. The results of this study are as follows: First, this study examined that with regard to paradigm, a theoretical frame to view universe, the dichotomous, determinist, mechanism, linear paradigm collapsed to convert to undetermined, exoteric, pluralistic, indeterministic, organic, and holistic paradigm. The new paradigm is identified to have emerged before and after 1950s, and through the new paradigm, the characteristics of postmodernism such as historicality, popularity, locality, folkways and the characteristics of deconstructionism, internally mutual text, post phenomenon, undeterminability and externally exposure, destruction, poverty, decomposition and analysis, were identified. Second, the Orient is defined as the generic term referring to the entire Asian areas east of Turkey. Through the developmental process of oriental images, it was converted from the Oriental image, which mysteriously and romantically represents oriental elements, into the ethnic image that represents long time oriental traditions and indigenous culture together with the characteristics of the new paradigm. Third, the artistic characteristics of the Oriental costumes presented by Korea, China and Japan are expressed in developmental types, T-type plane structure, layered style, asymmetrical adjustment and easy silhouette, and they show indigenous characteristics of each country, for example, Chinese styles in dragon pattern, red and yellow, Japanese styles in flower design and achromatic color. Fourth, the Oriental Image, combined with the postmodernism and deconstructionism through the new paradigm, has two: one Oriental image highlights traditional elements by creating new Oriental image such as natural image, folk image, hybrid image and deconstruction image; and another is undetermined and vague by combining or decomposing Oriental or Western elements. It is expected that fashion designs that reflect these contexts of the times will contribute to the strengthening of international competitiveness.

  • This study is to understand the work experiences of nursing students under preceptorship in 3+1 year program, and suggests effective practice to prevent stopping nursing profession. Four focus group interviews were made with 23 nursing students in 3+1 year program. Data were analyzed through the grounded theory of Corbin and Strauss' (2008). Through comparative analysis, central phenomenon of was 'looking for lighthouse'. The causal condition was 'opportunity to learning practice'. Contextual conditions were 'mood of being a true nurse', 'getting vivid information about clinical field', and 'lack of students perception about preceptorship'. Intervention conditions were 'work environment', 'proactive learning' and 'attachment to the hospital'. Action/interaction strategies were 'adjustment to diverse demands of patients and guardians', 'feeling as if it were one's own affair', and 'looking as much as knowing'. Consequence were 'pride' and 'itinerary of learning as a new graduate nurse'. This study is meaningful because it gives useful basis to nursing students in the process of 'looking for lighthouse'.

  • The aim of this study is to find out the time-series nexus of public debt and economic growth in Malaysia. For an upper-middle income country, Malaysia had experienced over 50% ratio of debt to GDP since 2009 until now. The question arises is whether this trend is healthy to the economy. With a focus into the debt-to-GDP ratio from 1970-2015, this study investigates the short-run and long-run relationship between public debt and economic growth in Malaysia. This study used secondary data by collecting time-series data (1970-2015) from the World Bank Data and Bank Negara Malaysia. Autoregressive Distributed Lag (ARDL) model is applied in this study to examine the relationship between debt and economic growth. Based on ARDL framework, it shows that there is a long-run effect between the debt and economic growth in Malaysia. While the significance value of Error Correction Term shows that there is a long-run adjustment in the short run. Generally, this study found government expenditures, in the long run, strongly influence the GDP per capita. Through the findings, the government expenditures could increase the GDP per capita. The study also reveals that any increment of the debt ratio will result in reduction of the GDP per capita.

  • This study intends to analyze the fit of directly-imported American casual pants for Korean female college students in terms of appearance and comfortableness. The authors carried out a wearing test with sample pants from 3 brands (DKNY: A, Gap: B, Polo: C) that had the most market share and that were mostly preferred by Korean female college students. Results showed that pants A had insufficient ease in the crotch, as the depth of the crotch was short. The hip girth received a low assessment in terms of appearance. Moreover, the hem widths were wide while the pants length was long. Pants B were expected to be most appropriate for Korean women's bodies, as they had the longest crotch depth among the three brands. However, the pants appeared to pull downward due to the narrow thigh and the knee girth and hem width. Moreover, the crotch girth and hip girth received a poor appearance assessment. Pants C were rated as satisfactory for their thigh girth, knee girth, and hem width. However, the crotch was uncomfortable, as it had a short crotch depth. The hip girth received a low appearance assessment. This study suggests that a pattern adjustment is required for directly-imported American pants to provide a better fit for the bodies of Korean women. The crotch depths should be approximately 17.5 cm. The hem widths should be approximately 20 cm. We also suggest a leg length of 75 cm, a waist girth of 86 cm, and a hip girth of 97 cm.

  • A descriptive study was conducted to describe the content of nursing interventions and incoming telephone calls from the parents whose child was discharged to home or who has planned immunization during the period from March 15, 1995 to November 30, 1995. Detailed notes on 145 telephone calls and 243 nursing interventions were recorded by head nurses on pediatiric nursing units were entered to data collection and content analysis. The results of the study are as follows : 1. Six analysis categories for the records on incoming telephone calls were identified judgement-dependence, dependent -coping, self-initiated coping, support, adjustment and intermediation need. 2. Five analytic categories for the records on telephone interventions were identified : guidance, mediation, facilitating self -care abilities, support, instrumental use. 3. Problems related to physical signs and symptoms, medication, immunization, and vital signs were most often cited as concerns by parents and caregivers. 4. Instruction, suggestion, provision knowledge and information, reassurance related to physical problems, medication, immunization and clinic visits were most often used as an nursing interventions by head nurses on pediatric nursing units. In spite of the fact that the telephone calls were initiated by the parents, dependency of parents during the telephone calls was remarkable. The dependency of parents on judgement and decision making of the pediatric nurses should be understood in terms of the psychosocial content as well as cultural characteristics. Therefore, it is suppested that telephone interventions focus on facilitating the self-care ability of the parents whose children have chronic conditions. The results of this study will be useful as an essential reference in providing effective for children and their families after discharged from the hospital. The results can also be used as reliable data for extended pediatric nursing service in the health care delivery system as well as for the development of telephone intervention service program in responding to the current health care environment.

  • The purpose of this study is to understand the school achievement of domestic adopted children in Korea and its related factors. Although the developmental outcomes of domestic adopted children were the focus of research interests, their school achievement has never been fully addressed in Korea. The subsample (9-17 years old) of 5th wave data of was used for the analysis. The results showed that the school achievement level of domestic adopted children was not significantly different from their non-adopted peers during elementary school years except the mathematics, but changed drastically after they entered the middle school, showing significantly lower level from their non-adopted peers. Factors related with the overall school achievement were the level of school, maternal education, age at adoption, child's self-esteem and school adjustment. For specific subject, however, significant factors were found to be somewhat different. Based on the results of the study, the practical guidelines to improve the school achievement of adopted children were suggested. Also, suggestions for the following studies were made.

  • Rapid social change affects residential environments and this in turn creates new stimuli to which people have to adapt. These stimuli have been seen to increase stress levels. Therefore, dwellers in these environments try to reduce stress through various methods. The purpose of this paper is to: 1) identify the general trends of coping styles about residential environmental stress, 2) analyze the differences in socio-demographic characteristics and how the physical characteristics of buildings affect stress, find out how personal backgrounds affect stress levels and the ability to get rid of environmental-related stress. The subjects in this study consisted of people living in multi-family housing in Gwangju. The city is divided into 5 districts and used quota sampling. 324 housewives were surveyed from the households by self-administered questionnaires. The survey was conducted in December, 2006, after the questionnaire was revised based on the results of preliminary survey. After all the questionnaires were collected, the data was coded and analyzed using the SPSS 12.0 program. This study confirmed that the manner in which those in multi-family housing coped with stress. Especially, we need a policy which seriously considers residents who are of low social-economic standing. As well as being exposed to residential environmental stress, they also have no means to deal with it. The age of a building had a strong impact on coping styles about residential environmental stress. We have to make special studies about the adaptive reuse of buildings for the reduction of residential environmental stress and to greatly improve coping styles. In conclusion, it emphasized the importance of education, information, and economic aid. Reasonable housing management would surely lead to a rise in residential satisfaction and the promotion of residential welfare.
