The purpose of this study was to suggest and prove that service design is not in the dimension of a simply new design methodology, but in the design paradigm change from conventional tangible and visual view of design to the intangible service of design. Based on a variety of literature research, this study defined service design, found its characteristics, and proved its differences from conventional design approaches and thoughts. To do that, this study looked into service design theories, processes, and methodologies, defined quality factor and availability of service design, and user satisfaction, and setup hypotheses to prove them. This study conducted a questionnaire survey with service design firms, service designers, and their customers. The questionnaire data were applied to structural equation to analyze the hypotheses. According to the analysis, reliability, tangibility, assurance, and empathy of the quality factors of service design were accepted, but responsiveness of the factors was rejected. It was found that quality factors positively influenced availability and ended up positively affecting user satisfaction. The quantitative research results will made some suggestions to service design firms and designers in the paradigm change to service-centric design, and will show the importance of understanding the essence of service in terms of design methodology.

Climate change affects all components of the global environment system and, in turn, all components mutually interact and affect climate change through non-linear feedback processes. It is thus necessary to study the interaction between the climate and the environment, in order to comprehensively understand and predict climate and environment change. However, current relevant systems are limited to particular areas and do not sufficiently support the mutual linking of research studies. Therefore, this study develops prototype a GIS based integrated DB management system for supporting the climate and environment data storage, management and distribution. The integrated DB management system was developed using VB.NET languages and ArcObjects component. First, considering the demands of climate environment experts, the study areas are selected and the methods of data management and utilization were defined. In addition, a location-based GIS DB was created in order to aid in understanding climate change through visual representation. Finally, the integrated DB management system provides an efficient data management and distribution data and it creates synergistic effect on climate and environment study. It also contributes significantly to the comprehensive diagnosis and prediction of climate change and environment systems.

Various difficulties and inconveniences arise from having a mentally handicapped child in a family and these place many demands on mothers. There are few studies in Korea on these demands nor on what mothers go through with their mentally handicapped daughters' menarche and puberty. The purpose of the study was to examine the experiences of mothers of mentally handicapped daughters, as it relates to their daughters' menarche and the beginning of puberty. With indepth interviews, both in person and by telephone and participant observation the study used a qualitative research methodology to attempt to understand the experiences of these mothers. The data were gathered from October 1995 to April 1996. The subjects for the research included nine mothers of mentally handicapped daughters whose ages ranged from 12 to 18 and who attended one of three special schools located in either Inchon or Seoul. The data were recorded and analyzed : meaningful statements were grouped according to subjects raised by the mothers. Content Analysis was also applied to identify similar content and confirm common experiences. and to highlight concepts and categorized them. The results of this study are as follows. Five categories were identified : mothers' emotional responses to their mentally handicapped daughters' menarche and menstration were of severe despair accompanied by anxiety, guilt, fear, anguish, shame and pity because the mothers were afraid their daughters would not be able to use appropriate hygienic measures during menstration and the mothers felt heavily burdened in having to look them. The mothers also had negative feelings about their daughters' physical development. The experience of mothers related to their daughters' possibilities for marriage and pregnancy were of powerlessness, distress, withdrawal, fear. pity and desperation and they were afraid that their daughters might be violated sexually. The mothers rejected the possibility of marriage and pregnancy for their daughters and instead planned very restricting futures for them. The mothers used various coping methods to bring meaning to their lives. Because the negative emotional responses of the mothers. nurses need to work to empower mothers to overcome these negative responses. Sex education can also play an important role especially for the daughters especially through the use of visual aids. Further, nurses should understand the tearing difficulties of mentally handicapped daughters, what mothers need and also what they experience with their mentally handicapped daughters. In conclusion, nurses should understand the negative experiences of the mothers in relation to their mentally handicapped daughters' menarche, help the mothers cope with the negative. emotions through real life education and counselling. In addition, there is a need for nursing interventions and an administrative system which will minimize the prejudices of society towards handicapped people.

Purpose: The aim of this study was to compare the effectiveness of hydroxyapatite containing toothpaste with positive control toothpastes in reducing dentine hypersensitivity. Materials and methods: This clinical trial was a double-blind, randomized, parallel group comparison of two, namely hydroxyapatite containing toothpaste and strontium chloride containing toothpaste. A total of 55 subjects were included in this study. The subjects were given randomly assigned one of the two toothpastes after received tooth brushing instruction at baseline. Some clinical indices(PI, GI, PD), verbal rating score(VRS) for sensitivity to stimulus, the effect in relieving sensitivity and visual analogue scale(VAS) for sensitivity at baseline, week 2, week 4 and week 8 were assessed. All data were evaluated by intention-to-treat analysis. Results: Overall, PI and GI scores were significantly reduced compare baseline in all groups(p<0.05). In addition, there was significant difference in PI at 4 weeks and in GI at 4, 8 weeks between groups. The proportions of subjects relieved sensitivity were 70.4% in experimental group and 57.1% in control group at 8 weeks respectively. The VRS for sensitivity to three kinds of stimuli and VAS for sensitivity decreased according to time, there was no overall difference between two groups(p>0.05). Conclusion: This study demonstrated that the new hydroxyapatite containing toothpaste was similarly effective in reducing dentine hypersensitivity with pre-existing benchmark toothpaste.

Surface Image Velocimetry (SIV) is a recently-developed discharge measurement instrument. It uses image processing techniques to measure the water surface velocity and estimate water discharge with given cross section. The present study aims to implement a FSIV (Fixed-type Surface Image Velocimetry) at Soojeon Bridge in the Dalcheon. The hardware system consists of two digital cameras, a computer, and a pressure-type water stage gauge. The images taken with the hardware system are sent to a server computer via a wireless internet, and analyzed with a image processing software (SIV software). The estimated discharges were compared with the observed discharges through Goesan dam spillway and index velocity method using ADVM. The computed results showed a good agreement with the observed one, except for the night time. The results compared with discharges through Goesan dam spillway reached around 5~10% in the case of discharge over 30 m3/s, and the results compared with discharges through index velocity method using ADVM reached around 5% in the case of discharge over 200 $m^3/s$. Considering the low cost of the system and the visual inspection of the site situation with the images, the SIV would be fairly good way to measure water discharge in real time.

This study investigated the confidence, satisfaction, and psychological safety and identified factors affecting the satisfaction of 41 paramedic students. Data, which consists of pre and post-confidence items on visual analogue scale, 21 satisfaction items and 10 psychological safety items was analyzed using SPSS WIN 21.0 program. After the simulation education, the students were told to write what they felt about the education. Then the students' comments, which were categorized as effectiveness and difficulty, were analyzed. Satisfaction of general characteristics showed a significant difference in age (t = -2.22, p = 0.03) and psychological safety of general characteristics showed a significant difference in gender (t = 3.70, p = 0.00) and age (t = -3.65, p = 0.00). Pre-confidence is low (4.37); however, post-confidence increased to 6.22. It showed a significant difference in pre and post-confidence (t = -5.878, p = 0.000). Satisfaction was correlated with psychological safety (r = 0.516, p = 0.001). The variables affecting satisfaction were psychological safety (t = 3.021, p = 0.005) and post-confidence (t = 1.936, p = 0.061). These variables accounted for 27.6% of the satisfaction according to a regression analysis. The simulation education may be the new effective paramedic education strategy of emergency childbirth. Repetitive simulation learning with further development of various scenarios, more education time, and more faculties will be able to train field compatible paramedics.

Overexcitaility (OE) as a concept that is related to developmental potential, has been shown to differ by intelligence, gender, involvement in school programs and artistic interest in American populations of students. Overexitability, used to describe the five ways that people might experience developmental potential for emotional growth, are emotional, intellectual, imaginational, sensual, and psychomotor. Little is known about the profiles of groups of gifted learners outside of studies conducted in the United States. In order to better understand the emotional needs of Korean students, the purpose of this study was to determine the overexcitability profiles of students enrolled in four high schools, each with a different domain focus: math and sciences, visual and performing arts, and foreign languages. 341 subjects of this study completed the Overexcitability Questionnaire II. Multivariate Analysis of Variance (MANOVA) was conducted to determine statistical differences. The results showed that Mean scores of psychomotor, sensual and imaginational are highest in the Art High School, intellectual is highest in the Science High School and emotional is highest in the Foreign Language High School. There were significant differences among the schools. Each major also showed significant difference. The results showed that mean score of psychomotor is highest in the Dance major, sensual, imaginational and emotional are highest in the Drama majore and intellectual is highest in the Science major. The results showed that the mean scores of psychomotor, imaginational and intellectual are higher in the male students than female students. On the other hand the mean scores of sensual and emotional are higher in the female students than in the male students.
