Objectives : The purpose of this study is to seek analysis of related factors for dental fear and to know the fear component affecting the treatment of the dental treatment. Methods : Total of 320 females and males aging from 10 to 40 years old with dental treatments done from May to July 2010 have participated with self-entry survey method utilizing the Dental Fear Survey questionnaire. The data received was analyzed using the descriptive statistic, t-test, ANOVA and multiple correlation analysis with level of significance as p<0.05. Results : The dental fear factor were significantly high in woman by $2.79{\pm}0.92$ and in 40's age group by $2.82{\pm}0.84$ (p<0.05). Participants with frequent tooth ache, experiencing pain while treating the tooth ache and breaking the dental treatment appointment showed higher fear factor. Thoughts of having poor dental health condition caused bad influence on fear factor. Overall, the factors affecting the fear of the dental treatments were gender, an ache while treating, number of missed appointment, and distrust of the dentist, stimulation factor were the factors affecting the treatment. Conclusions : The fear factors in the dental treatment were higher with gender, related characteristics of the oral health and distrust of the dentist. Therefore accurately recognizing the sensitive patient with dental treatment, proper management of the toothache, effort to increase the creditability of the doctors and separately treating patient customized for each individual patient will reduce the fear of the dental treatment.

This study examined the traditional edible basis and ingredients of Song-gi used for Pyeon of Jong-ga ancestral ritual food. Through an investigation of references, a case study, and ingredient analysis for traditional edible basis of Song-gi, the nutritional value and availability as food material were reviewed. Among the 4 kinds of pine trees from 4,705 types of edible materials usable as food listed in the ${\ll}$Korea Food Standards Codex${\gg}$, 'Pinus radiata D. Don', in which the husk is acknowledged as an edible food, was applied in this study. This study processed the Song-gi following the method of jong-ga and divided into pine inner bark (PIB) and pine inner bark powder (PIBP) to analyze the general composition and dietary fiber. The main composition of PIB was carbohydrate, in which the content was 88.7% per 100 g. The content of dietary fiber was 73.7% per 100 g and the insoluble dietary fiber reached 92.3% in total dietary fiber. In conclusion, the edibility of Song-gi, which has a considerable amount of insoluble dietary fiber caused constipation because it absorbed the moisture in the intestine due to the lack of nutrients but may be developed as a functional food that helps the digestive activation of the intestine and improve the health of the intestine if taken with balanced nutrition.

Since astrocytes were shown to play a central role in maintaining neuronal viability both under normal conditions and during stress such as ischemia, studies of the astrocytic response to stress are essential to understand many types of brain pathology. The micro array system permitted screening of large numbers of genes in biological or pathological processes. Therefore, the gene expression patterns in the in vitro model of astrocytes following exposure to oxygen-glucose deprivation (OGD) were evaluated by using the micro array analysis. Primary astrocytic cultures were prepared from postnatal Swiss Webster mice. The cells were exposed to OGD for 4 hrs at $37^{\circ}C$ prior to cell harvesting. From the cultured cells, we isolated mRNA, synthesized cDNA, converted to biotinylated cRNA and then reacted with GeneChips. The data were normalized and analyzed using dChip and GenMAPP tools. After 4 hrs exposure to OGD, 4 genes were increased more than 2 folds and 51 genes were decreased more than 2 folds compared with the control condition. The data suggest that the OGD has general suppressive effect on the gene expression with the exception of some genes which are related with ischemic cell death directly or indirectly. These genes are mainly involved in apoptotic and protein translation pathways and gap junction component. These results suggest that microarray analysis of gene expression may be useful for screening novel molecular mediators of astrocyte response to ischemic injury and making profound understanding of the cellular mechanisms as a whole. Such a screening technique should provide insights into the molecular basis of brain disorders and help to identify potential targets for therapy.

Meat provides high quality proteins, lipids, minerals and vitamins. The meat protein is especially high in essential amino acids that are crucial for human health, growth & development and for the formation of enzymes, hormones and antibodies. Relatively cheap and nutritionally sound vegetable proteins that are similar to animal proteins are being developed to replace the animal proteins in texture, nutrition and food characteristics. In this study a nutritionally sound meat lipid replacing food Oatrim that has been produced by converting oat starch into maltodextrin by ${\alpha}$-amylase, have been partially substituted for beef and general component analysis, texture measurement and sensory tests have been conducted. The results are 1. Water content of the non-treated (0% treated) was 67.1% and the treated (10% treated) was 77%. The treated showed better water holding capacity. 2. Protein content of the non-treated was 21.2 g/100 g; the 4% treated, 18.4 g/100 g; the 6% treated, 18.2 g/100 g; the 8% treated, 17.2 g/100g; and the 10% treated, 16.0 g/100 g. The protein content tended significant. 3. Amino acid analysis results showed that glutamic acid content was the highest in Oatrim and as its amino acid make up is exellent, it is valuable as a fine low fat protein food. 4. Sensory tests show that the increased Oatrim content increased the appearance quality but food characteristics were high only in the 4% and 6% treated groups, indicating that the replacement ratio should not exceed 10%. 5. Texture measurement analysis results show that the higher the replacement content, lower the springness, cohesiveness, hardness, chewiness and gumminess, resulting in relatively soft overall texture. However, in order to better the food characteristics, more studies must be continuously done, and so by being able to increase vegetable substitution over meat, it may be able to contribute to the prevention of adult disease.

Recently, many organizations are actively adopting VDI (Virtual Desktop Infrastructure), an IT-based business system, to build a non-face-to-face business environment for smart-work. However, most of the existing research on VDI has focused on the satisfaction of system service quality or the use of IT resources and investment for VDI introduction. However, research on effective management and utilization of factors according to the characteristics of VDI technology is urgently required. This study is an empirical research study on how VDI technology characteristics affect interactions and work performance by identifying differences in utilization factors between general organization members and IT managers, presenting standards for business utilization and management. This study proposed a model and hypothesis that the system technology characteristics for VDI use are mediated by interactions in which users respond to functions appropriate to their work. In order to verify the hypothesis, a questionnaire survey was conducted on 188 people of companies and institutions that have adopted and used VDI through a questionnaire survey. Data analysis was performed with partial least squares (PLS), a structural equation modeling (SEM) technique that uses a component-based approach to estimation. As a result of the empirical analysis, the same environmental function for performing work, N-th security, and remote access function factors for non-face-to-face work have a significant effect on interactivity, and IT managers have an additional significant effect on the management technology characteristics of resource reallocation. Has been shown to affect. The results of this study aim to minimize trial and error due to new introduction by presenting considerations for future VDI introduction through case analysis.

Purpose: This study aimed to conduct a job analysis of nurse carecoordinators and to identify the frequency, importance and difficulty of each task of their job. Methods: A committee for developing a curriculum (DACUM) was formed and members of the committee defined nurse care coordinators' jobs and enumerated the duties, tasks and task elements by applying the DACUM technique. Then nurse care coordinators enrolled in the pilot project evaluated the frequency, importance and difficulty of each task. Results: From the job descriptions of nurse care coordinators, we identified 12 duties and 42 tasks. Each task comprised 1~5 task elements. Among tasks, 'assess the patient's general health status' was carried out most frequently. Nurse care coordinators perceived that 'check vital signs' and 'strengthen patient competence to promote health behaviors' were more important than all other tasks. The most difficult task was 'develop professionalism as a nurse care coordinator'. Conclusion: The nurse care coordinators' roles developed in this study will serve as the key guidelines for human resource management of care coordinators. Further, job specifications for nurse care coordinators need to be developed, which is necessary for designing education and training programs. We also need to integrate primary health care as an essential component in nursing education.

This study tires to examine affects that job and socio-psychological stresses of female office workers influence job satisfaction, organization commitment, and leaving intentions. A complete data are collected by conducting a survey with 240 female office workers from 9 medical institutions regarded as almost general hospital in Seoul. It is analyzed that the relation between socio-psychological stress and job satisfaction, organization commitment, and leaving intentions by using t-test; analysis of variance; correlation analysis; principal component analysis; linear structural equation modeling; etc. The results of this study are summarized as following. First, as it was comprehended by specific characteristics of subjects that the female office workers' level of job and socio-psychological stress, job satisfaction, organizational commitment, and leaving intention, there were statistically significant distinctions from their age, marital status, presence of children, position in the organization, type of employment, and monthly average income. Second, this study regarded relationship between the female office workers' level of job and socio-psychological stresses, job satisfaction, organizational commitment, and leaving intention. Job and socio-psychological stresses were negatively correlated with job satisfaction and organizational commitment, but the stresses were positive with leaving intention. Third, after evaluating effect that 8 features related to the job stress could influence job stress, the most effective valuables were in order to unfairness in organizational structure, workplace culture, inadequate compensation, and relationship conflict. Fourth, when looking at the overall effects of the job and sociopsychological stresses on job satisfaction, organizational commitment, and leaving intention, work autonomy was the most influencing factor of work stress levels. The level of the job stress seemed to be a prevalent impact on the leaving intention and it showed the most negative relationship that path coefficient from leaving intention to organizational commitment and also from organizational commitment to job satisfaction. Based on these findings, it can be defined that the job and socio-psychological stresses strongly influence job satisfaction, organizational commitment, and leaving intention.

Human posture recognition has attracted tremendous attention in ubiquitous environment, performing arts and robot control so that, recently, many researchers in pattern recognition and computer vision are working to make efficient posture recognition system. However the most of existing studies is very sensitive to human variations such as the rotation or the translation of body. This is why the feature, which is extracted from the feature extraction part as the first step of general posture recognition system, is influenced by these variations. To alleviate these human variations and improve the posture recognition result, this paper presents 3D Star Skeleton and Principle Component Analysis (PCA) based feature extraction methods in the multi-view environment. The proposed system use the 8 projection maps, a kind of depth map, as an input data. And the projection maps are extracted from the visual hull generation process. Though these data, the system constructs 3D Star Skeleton and extracts the rotation invariant feature using PCA. In experimental result, we extract the feature from the 3D Star Skeleton and recognize the human posture using the feature. Finally we prove that the proposed method is robust to human variations.
