The study subjects in this study are 295 workers who work on one electronics industry, and they were composed of 93 VDT and 202 non-VDT workers. This study was carried out to obtain the prevalence of subjective symptoms and to compare psychological symptom scores from SCL-90-R between VDT and non-VDT work groups. And to verify the relationship between VDT work related symptoms and psychological symptoms, the author compared SCL-90-R T scores between symptom complaining and non-complaining groups. The results are summarized as follows : 1. Throughout the prevalence study of VDT work related symptoms according to VDT work state, the author could select the final 10 symptoms by sex;'eye fatigue', 'foggy vision', 'neck discomfort or pain', 'shoulder discomfort and pain', 'light headedness', 'dizziness', 'acne', 'itching sensation on face', 'difficulty in concentration', 'memory disturbance' in males, and 'blurred vision', 'foggy vision', 'neck discomfort or pain', 'shoulder discomfort and pain', 'abdominal distention', 'indigestion', 'acne', 'prickling sensation on face', 'difficulty in concentration', 'memory disturbance' in females. 2. Throughout comparison of psychological symptom scores from SCL-90-R between VDT and non-VDT workers, except 'Interpersonal sensitivity' in female, Mean T score were higher in VDT workers, but not significantly different between the two groups. These results indicate that the relation between VDT work status and psychological symptoms are not strongly correlated. 3. Because of the nonspecific characteristics of VDT work related symptoms, from the 40 subjective symptoms, the author selected the final 10 symptoms by sex, especially correlated to VDT, and divided the study subjects into symptom complaining and non-complaining groups. The mean SCL-90-R T scores between the two groups were compared. Except for the opthalmologic symptoms in females, the scores were significantly different between the two groups in all symptoms. And this indicates that the VDT work related symptoms strongly correlated with the present individual psychological conditions. 4. Due to understand that which of the 9 psychological symptom dimensions are strongly correlated with the subjective symptoms, the author excuted muliple logistic regression analysis, and the result were as follows; 'depression' and 'somatization', in male, and 'obsessive-compulsive' and 'somatization' in female.

In empirical studies on rural development projects, differentiation tends to be considered a strategy aimed at increasing the number of visitors. Rural development projects include the improvement of living environment, and the discussion about project goals and evaluation of project results are often focused on the aspect of rural tourism. Thus, subjective benefits of such projects for residents are omitted. This study examines the meaning of differentiation from the perspective of residents and explores the validity of the number of visitors and the possibility of reflecting residents' subjective score as evaluation indicators for a project. To achieve such an objective, this study uses survey data collected from 153 people in 38 comprehensive development projects in areas of Eup and Myeon, Korea. The results of this study show that differentiation is viewed as a by-product of positive improvement from a rural development project, from the perspective of residents. The effects of rural development are classified into two dimensions: socioeconomic effects and living environmental effects. Landscape improvement is included in the dimension of living environmental effects and an increase in the number of visitors is included in the dimension of socioeconomic effects. As such, they are confirmed to be the factors that determine the level of differentiation. For example, the increase in the number of visitors is confirmed to be a valid indicator of project success, in which two-dimensional characters are reflected. The level of differentiation evaluated by residents is a result of the workings of the above two factors. Unlike in previous studies, the possibility of evaluation based on the perception of residents is confirmed in the evaluation of results. When the level of differentiation is interpreted as the direct result of a project, the number of visitors has an impact on socioeconomic effects, and the project content of landscape improvement has an impact on living environmental effects. The goal of policy and residents is the same in terms of the effort residents may make in maximizing results of a project by themselves; thus, the government's goal is achieved even when a project is carried out under the autonomy of residents. Ultimately, the government should focus on providing conditions in which active citizen participation can not only occur but help to establish a policy direction, which subsequently strengthens the substantial rights of residents.

The purpose of this study was to compare arch dimensions and frequency distribution of arch forms between Korean and Japanese Class I, II, and III malocclusion groups. Methods: The sample consisted of 368 Korean cases (114 Class I, 119 Class II, and 135 Class III malocclusion) and 160 Japanese cases (60 Class I, 50 Class II, and 50 Class III malocclusion). The most facial portion of 13 proximal contact areas was digitized from photocopied images of the mandibular dental arches. Clinical bracket slot points were calculated for each tooth based on mandibular tooth thickness data. Four linear and two proportional measurements were taken. Measurements are statistically analyzed in each malocclusion group. The dental arches were classified into square, ovoid, and tapered forms to determine and compare the frequency distributions between the two ethnic groups. Results: The findings of this study showed that Japanese females in Class I and II groups had a statistically significant narrower mandibular dental arch width compared with the Japanese males, Korean males and Korean females. But in the Class III group, there was no significant difference in the mandibular dental arch size according to the two ethnic groups and genders. Conclusions: The majority of Koreans and Japanese in all the malocclusion groups exhibited square and ovoid arch forms. The most frequent arch forms found in Koreans was square but ovoid for Japanese.

This longitudinal quasi-experimental research was conducted to develop parent role education program and to evaluate the effect of this program for mother-infant interaction, childrearing environment and infant development. The subjects were the healthy infants weighing over 2,500gm at birth, whose gestational age was more than 37weeks, and their healthy mothers. The sample consisted of eighteen mother-infant dyads for intervention group and sixteen dyads for control group. Data were collected from March 15th in 1999 to Jun 20th in 2000. The intervention group received programmed education consisted of discharge education, telephone counselling, and home visiting care. But control group were collected data without programmed education. In this study, the Nursing Child Assessment Teaching Scale(NCATS) devised by Barnard was used to determine the mother-infant interaction, HOME was used to determine the childrearing environment, and Griffiths mental development scale was used to determine the infant development. The data were analyzed using SPSS Win using chi-square test, t-test, and repeated measure ANOVA. This study was focused on the results of twelve months time point. Summaries of the results were as follows: 1. There was no significant difference in mother-infant interaction(NCATS) between intervention group and control group. But both of two groups showed significantly higher in interaction score at twelve months than at six months in the subscales of social-emotional growth fostering, and responsiveness to caregiver. 2. There was no significant difference in childrearing environment(HOME) between two groups at twelve months. But when each subscale of HOME was examined, intervention group showed higher scores in the dimensions of maternal involvement with child(p=.001), and maternal emotional-verbal responsivity(p=.048). 3. There was no significant difference in GQ of the Griffiths mental development scale between two groups, although significant difference was found in performance subscale. 4. Infant development at twelve months showed significant correlation with mother-infant interaction and childrearing environment at six months, although mother-infant interaction and childrearing environment at twelve months did not show significant correlations with infant development at twelve months. 5. Developmental scores at six months showed significant correlations with variety in daily stimulation, and mother's emotional, verbal responsivity, whereas developmental scores at twelve months showed significant correlations with acceptance of child behavior at six months, and appropriate play material at twelve months. In conclusion, the maternal education program for primipara showed long term effect in some categories in organizing the childrearing environment, and fostering the infant development. We suggest further study and implications of parent role education program for high risk parents such as parents in low economic status or with premature babies.

Purpose: This study was performed to assess the reproducibility of identifying the sella turcica landmark in a three-dimensional (3D) model by using a new sella-specific landmark reference system. Materials and Methods: Thirty-two cone-beam computed tomographic scans (3D Accuitomo$^{(R)}$ 170, J. Morita, Kyoto, Japan) were retrospectively collected. The 3D data were exported into the Digital Imaging and Communications in Medicine standard and then imported into the Maxilim$^{(R)}$ software (Medicim NV, Sint-Niklaas, Belgium) to create 3D surface models. Five observers identified four osseous landmarks in order to create the reference frame and then identified two sella landmarks. The x, y, and z coordinates of each landmark were exported. The observations were repeated after four weeks. Statistical analysis was performed using the multiple paired t-test with Bonferroni correction (intraobserver precision: p<0.005, interobserver precision: p<0.0011). Results: The intraobserver mean precision of all landmarks was <1 mm. Significant differences were found when comparing the intraobserver precision of each observer (p<0.005). For the sella landmarks, the intraobserver mean precision ranged from $0.43{\pm}0.34mm$ to $0.51{\pm}0.46mm$. The intraobserver reproducibility was generally good. The overall interobserver mean precision was <1 mm. Significant differences between each pair of observers for all anatomical landmarks were found (p<0.0011). The interobserver reproducibility of sella landmarks was good, with >50% precision in locating the landmark within 1 mm. Conclusion: A newly developed reference system offers high precision and reproducibility for sella turcica identification in a 3D model without being based on two-dimensional images derived from 3D data.

This article attempts to restructurize the current arguments on how to change the method of financing child care programme, which is currently under discussion in Korea. There has been a series of changes in Korean child care policy, such as the amendment of Child Care Act, the transition of its responsible administrations, adoption the child care policy as a national agenda. In these changes, new needs for child care financing method comes out with a new direction of child care policy and a plan of expansion of finances. That's the transition from 'facility-centered subsidy' to 'child-centered subsidy'. This article redefine it as the arguments about 'supply-side subsidy' vs. 'demand-side subsidy'. To analyse the different traits of two branches of arguments, this article reviews the social welfare models, and has come to the conclusion that the Burchardt's model is appropriate to explain the financing debates. Thus, the analysis the traits of the two perspectives is based on three dimensions i. e. service provision, financing and decision making according to the Burchardt's model. This also examines how the two sides is connected to the discussion of publicity and quality improvement of child care service. Through this approaches and analysis, this helps us restructurize the debates on the method of financing from the present superficial arguments.

Recent research indicates that the new mothers want to learn about childrearing, and have burden in care of infants. Also it indicates that the new mothers say the lack of confidence and knowledge about infant care. This study was a prospective longitudinal reseach developing parent role education program and evaluating the effectiveness of this program for mother-infant interaction, childrearing environment and infant development. Longitudinal quasi-experimental design was used. The subjects were the healthy infants weighing over 2,500gm at birth, whose gestational age was more than 37weeks, and their mothers. The sample consisted of 19 mother-infant dyads for intervention group and 18 dyads for control group. Data were collected from March 15th to December 14th in 1999. For the intervention group received programmed education that was consisted of discharge education, telephone counselling, and home visiting for maternal education. The data were analyzed using chi-square test and t-test to test the equivalence of two groups, and the effectiveness of intervention program. This study was focused on the results of six months time point. The results were as follows: 1. There was significant difference in the mean score of mother-infant interaction(NCAST) between two groups. Intervention group showed higher scores in the subscales of sensitivity to cues, cognitive growth fostering, and caregiver total. 2. There was no significant difference in the mean score of child rearing environment (HOME) between two groups of six-month-infants. But when each subscale of HOME was examined, intervention group showed higher scores in the dimensions of opportunities for variety in daily stimulation, maternal involvement with child, and emotional, verbal response. 3. Six-month-infants of the intervention group showed significantly higher GQ in the Griffiths mental development scale. In conclusion, the maternal education program was effective in promoting the mother-infant interaction, organizing the childrearing environment, and fostering the infant development. These results were very meaningful that we found parent role education necessary for normal infants' mothers, and nurses can make a great contribution in promoting health of infants and mothers.

Central government of Korea devised the balanced national development as one of important agenda of government administration, and set up special act for balanced national development. According to special act, a plan to transfer public institutions to local areas was publicized on June 24, 2005. Thus 175 public institutions located in the capital area will be transfered to 11 local governments, and innovative cities will be built in local areas until 2012. However, Gwangju and Jeonnam province adopted not two individual innovative cities but one common innovative city in cooperation with two local governments. This study focuses on the characteristics of location selection process of common innovative city in Gwangju and Jeonnam province. Discussion about construction of common innovative city was started in need of new model for common development of two provinces, and most of peoples agreed a plan to establish on common innovative city within Jeonnam area near Gwangju area. Gwangju Jeonnam Regional Innovation Council, in particular, played an important role in the process of location selection and initial discussion about common innovative city. In addition, Common innovative city to be built in Naju city will be provided positive regional development effects in several dimensions. In result, it has been evaluated as a successful model of innovative city to be constructed with transfer of public institutions to local areas.

A distribution study of glitter was conducted from a local university building. The potential recipient surfaces chosen were the 1,000 chairs kept in 16 separate classrooms of the building. The surface of chairs contacting with buttocks and back of users were tape lifted with commercial adhesive tapes, and the surface of adhesive tapes were examined with a stereomicroscope to locate the glitters. 12 glitter particles were found from 11 chairs kept in 16 classrooms of a building. This result indicates that the possibility of glitter finding from Korean violent crime scene is high. The 12 glitters found from the chairs were analyzed with a stereomicroscope and an FTIR spectrophotometer to find the matching glitter. The stereomicroscope was used for the observation of the shapes, dimensions, colors and holograms of each glitter, and the FTIR spectrophotometer was used for the analysis of the chemical composition of the coating material of each glitter. The examination results revealed that 8 glitters out of 12 glitters were not sharing the common origin each other. Also, two glitters found from two separate classroom chairs share common microscopic and FTIR spectroscopic characteristics which indicating two glitters share common origin. The record of the students who had used the classrooms was traced and the authors could find that the classrooms where the same glitters were found were shared by a group of students who listen to the same class. This result implies that the path of the involved people should be considered while assessing the value of trace evidence.

Gaston Bachelard had a revolutionary progress in the field of human understanding by proposing his theory of image and imagination. His theory of the new image was so powerful, almost all areas of human science, particularly that of literary criticism, were strongly influenced and this influence continues until today. Today almost everyone accepts his theory of the image without much objection, but not rarely asked where began his transfer from the philosophy of science to the images. We propose a hypothesis that the beginning of the new concept of Bachelard's image was inspired by studies of contemporary science, especially quantum mechanics. The Heisenberg's uncertainty principle was the core of quantum mechanics, and opens new perspectives on the material world. We could summarize the message of the uncertainty principle : the material world is made up of various layers, and the material can not be measured by the location and movement at the same time. So we must have a new point of view of another dimension to know this material world. Bachelard had accepted this view of Heisenberg and developed his own theory of epistemological rupture. What is revolutionary in the theory of Bachelard's image is the fact that he looked at the images with the new perspective. The human psyche is another world compared to the rational world that dominates our daily lives. Bachelard insists that the image can not be explained by the concept. The fantasy world is a totally different world to that of rationality. That is why it can not be explained by the language of rationality as the concept. The imaginary world exists independently of the real world, but it is superimposed on the real world. These two worlds are influencing each other, and it is between these two world where our daily lives continues. The declaration of Bachelard 'image is a specific reality' is never a metaphor or rhetorical expression. This is an ontological expression that must truthfully. The imaginary world is a world built on the image and it works according to its own law. It is not a representation or copy of the real world. But the world of imagination are not alone. It exists in the same time and space with the world of science. It is superimposed with the world of science. Both two world influence each other. Bachelard has made a revolutionary change by studying the images. He gave them their own place. It has changed the views on the images that were treated as mere representations of reality. Thanks to him, the image can have its own value, that of a factor that creates reality. Bachelard shows how we can go deep into the source of being and the universe if we look at the pictures with the eyes of other dimensions.
