래피드 프로토 타이핑 기술은 일반적으로 제품의 사용 성(usability)을 미리 평가해 볼 수 있는 효과적 방법으로 여겨지고 있다. 그러나 아직까지 래피드 프로토 타이핑(rapid prototyping)에 의해 생성한 프로 타이프(prototype)를 가지고 사용 성 평가를 할 경우, 실제품으로 할 경우에 비교해 사용자 행위상에 어떤 차이가 있는 지에 대해서는 충분한 검증이 없었다. 본 연구의 목적은 래피드 프로토 타이핑에 의해 생성한 프로토 타이프가 실제품을 대신해 사용 성 평가에 사용될 수 있는 가를 검증하는 것이다. 이를 위해 우선 가전제품 중 사용자 인터페이스(user interface)가 비교적 단순한 냉장고의 제어 표시판(control-display)을 대상으로 한 실험을 수행하였다. 16명의 여자 피 실험 자 들이 피 실험 자간 실험(between-subjects)에 실험에 참여하여, 8명은 실제 냉장고의 제어 표시 판을 사용했고 나머지 8은 프로토 타이프를 사용했다. 각 그를 모두 냉장고 제어 표시 판의 대표적 기능인 시계조작, 절전냉장, 쾌속냉동 등 세 작업을 수행하도록 했다. 실제 품과 프로토 타이프의 차이는 작업 실패율, 작업완수 시간, 버튼 조작 회수 측면에서 분석되었다. 비 모수 검정(non-parametric)에 의한 분석 결과, 실제 품과 프로토 타이프 사이에 통계적 유의한 차이는 없는 것으로 나타났다. 이는 냉장고와 같이 비교적 단순한 제품의 사용 성 평가에는 래피드 프로토타이핑 기술의 효과적으로 사용될 수 있음을 보여준 결과라고 할 수 있다.

Background : It is very common in Korea to take care of non-acute patients in an acute setting, due to the lack of long-term facilities. Long term hospitalization increase medical expenses and decreases the bed utilization, which can affect the urgent and emergent admissions, and eventually jeopardize the hospital financially. In this study, strategies for effective transfers to the lower levels of care, and to decrease the length of stay were presented by surveying and analyzing the patient's knowledge of the transfer needs, and the willingness to transfer those whose hospital length of stay was more than 30days. Method : The survey is subject to a group of 251 patients who have been hospitalized over 30 days in a general hospital in Seoul. Excluding those that were in the Intensive Care Unit and psychiatric ward, 214 in-patients were used as participants. They were surveyed from April 9, 2002 to April 17, 2002. One hundred and thirty seven out of 214 were responded which made the response rate 64%. Data were analyzed by SAS and SPSS. Result : Multi-variable Logistic Regression Analysis showed a significant effect in medical expenses, knowledge of referral system and the information of the receiving hospital. The financial burden in medical expenses made the patient 10.7 times more willing to be transferred, knowledge of the referral system made them 5 times more willing to be transferred, and the information of receiving hospital makes 6.5 times more willing to be transferred. Reasons for willing to be transferred to a lower level of care were the phase of physical therapy, the distance from home, the attending physician's advice and being unable to be treated as an out patient. Reasons for refusing to be transferred were the following. The attending physician's competency, not being ready to be discharged, not trusting the receiving hospital's competency due to the lack of information, or never hearing about the referring system by the attending physician. Conclusion : Based on this, strategies for the effective transfer to the lower levels of care were suggested. It is desirable for the attending physician to be actively involved by making an effort to explain the transfer need, and referring to the Healthcare Coordinating Center, which can help the patient make the right decision. Nationwide networking for the referral system is the another key factor that may need to be suggested as an alternative to decrease the medical expenses. Collaborating with the Home Health Agency for the early discharge planning and the Social Service Department for financial aid are also needed. It is recommended that the hospital should expedite the transfer process by prioritizing the cost and the information as medical expenses, knowledge of referring system and the information of the receiving hospital, are the most important factors to the willingness to transfer to a lower level of care.

Accidents are important causes of death and disability in children. They also have enormous financial implications. Young children become an victim of accidents easily because of their physical fragileness and their coping behavior being vulnerable to any actions taken by accidents. Once they have a accident, the children whose not fully developed, suffer from devastating long-term after-effects. Lee, Lee, Kang and Han(1995) reported that ninety percent of accidents can be prevented. But there is no national system to manage, evaluate and analyse the information about child accidents, even though it is necessary for accident prevention policies and health promotion of the general public. The purpose of the study was to determine how often children have accidents and define the accident prevention strategies in children. The investigator conducted a descriptive study by performing the surveys, interviews, and workshops for the 2,458 young children, 10 teachers, and 1,494 parents. The data collection for the study began on September 2000 and completed on April 20, 2001. The analysis of the data was done with Window SPSS 10.0 for descriptive statistics. Among those children, 1,298 children(52.8％) injured from accidents. The children who had accident answered that they injured from traffic accident(27.3％), inside the home(26.3％), on the playground(17.0％), during playtime(13.6％), in the school(5.9％) and food poisoning(7.1％). To define accident prevention strategies for the school children, the parents and the teachers who had a special interest in this topic formed a special task force under the guidance of the investigator. The team was charged to prepare the basis of content materials by identifying the problems, setting standards for the program, prioritizing the process, and selecting the methods of implementation and evaluation. Eight issues and concerns identified by the team were: 1)allowing young children to learn undesirable habits and behaviors that would bother others without knowing; 2) not guarding young children from car accident; 3)unattended accident at playground; 4) considering home places safe; 5)unattended accident at school. These issues were found to be coinciding with the actual child accident cases occurred recent years in Korea. Greater efforts are required to reduce unnecessary deaths and disability from childhood accidents. This study gave a very useful and important data to prepare accident prevention educational program and to prepare accident prevention strategies.

본 연구는 정책의제형성이 외부집단에 의해 형성된 정책이라기 보다는 정치의 흐름중에서 정부와 여당의 역할이 크게 기여했다는 점과 국내외의 국민을 대표하는 상징적인 정책이라는 점이다. 특히 이주노동자와 결혼이주여성 정책은 글로벌 시대에 해결해야할 중요한 정책이라는 점과 정부가 추진하는 '결혼이주여성 정책'의 결정과정을 살펴봄으로써 정책에 결정적으로 영향을 미친 요인을 확인하기 위한 좋은 사례이기 때문이다. 이러한 연구목적을 달성하기 위한 구체적인 방안은 다음과 같다. 한국 다문화정책에 대한 이론적 논의를 진행하고, 다문화 정책이 형성되는 과정을 논의한다. 진행 단계에서는 다문화담론의 형성과정과 다문화담론이 다양하게 이루어지는 분화과정, 그리고 부문별로 이루어지던 다문화담론의 정책화되는 과정이다.

The purpose of this study was to 1) investigate the characteristics of burnout of Korean elementary school students and 2) develop and validate the Korean Academic Burnout Scale-Elementary School Students (KABS-ESS). Fifty-one behavioral descriptions of burnout extracted through a preliminary survey, focus group interview, and literature review were administered to a sample of 531 elementary students of the 4th to 6th grade in Gyeonggi Province. The results of an exploratory factor analysis indicated that the structure of the burnout of Korean elementary school students consists of seven factors (i.e., inefficacy, avoidance, cynicism, emotional exhaustion, physical exhaustion, antipathy and cognitive exhaustion), and this structure of final 28 items was confirmed by the confirmatory factor analysis. The KABS-ESS showed a correlation of .771 with a representative academic burnout scale, Maslach Burnout Inventory-Student Survey, and -.561 with the academic engagement scale, indicating that both convergent and discriminant validities were confirmed. Furthermore, all fit indices of the structural equation model of the Schaufeli and Bakker's job demands-resources in an academic setting were satisfactory, and the possibility of the validity generalization of the model was supported. The demand variables predicting academic burnout and engagement were academic overload and parental pressure, while self-resilience, self-regulated learning strategies, and parental and the teacher's support were identified as the resource variables. Lastly, the implications and future direction of the present study were discussed.

This study conducts a questionnaire with undergraduate students in the Dept. of Architecture who will lead the architectural field in future, examines environment and perception of CAD in their home and universities and aims at supplying the data required for setting CAD educational index and building its use environment, and it could obtain the following results. Individual CAD environment of undergraduate students in the Dept. of Architecture reach a considerable level in hardware part, but they don't have the same level in software part as the hardware and use illegal copy programs. It is shown that they spend their time in using CAD for five to eight hours a week and its main purposes are to perform a project related to architectural design or make report requiring drawing. Major places using CAD are CAD room in university or public PC room equipped with CAD compared to their own houses and most of them have a negative recognition of the convenience of its use. Their satisfaction with CAD use is considerably high and when they submitted their assignments of architectural design project by means of CAD, they had a positive evaluation from their professors and they have such hopes that 'Korean Support Strengthening', 'lowering price through version supply for students' and 'diversification of design symbol' in CAD S/W, and especially, most of respondents have an intention to purchase the original goods when version only for students will be marketed in future. Accordingly, for a qualitative improvement of CAD environment for undergraduate students in the Dept. of Architecture, universities must be equipped with the various types of CAD S/W and Applications and students' opportunity to access them should be increased. In addition, a method which can enhance using convenience of CAD room and PC room is required and CAD related S/W developers must market the version for students which consider the reality of undergraduates in Korea properly with an appropriate price level in order to settle a sound S/W culture.

PURPOSE: The purpose of this study was to compare the effects of Graston and self-myofascial release (SMR) techniques on knee joint flexibility, hamstring, and quadriceps strength. METHODS: Twenty subjects with hamstring shortness participated in this study. The subjects were assigned randomly to one of two groups: The Graston technique (GT) group received intervention using a Graston instrument for one minute, and the SMR group performed self-exercises using a foam roll for one minute. The range of motion (ROM) of the knee joint was measured by active knee extension test, and a handheld dynamometer was utilized to collect the hamstring and quadriceps muscle strength. This experiment was performed by two physical therapists. The significant level was set at ${\alpha}$=0.05. RESULTS: The results were as follows: 1) The ROM of the knee joint and quadriceps muscle strength were significantly increased in both groups. 2) Hamstring muscle strength was significantly reduced in both groups. 3) There were no significant differences between the GT group and SMR group for any variable. CONCLUSION: The results of this study suggest that SMR is an effective and easy technique for restoring proper muscle length and strength in subjects with hamstring shortness. We recommend that SMR technique be used for treat hamstring shortness in clinical setting and home-program.

This study surveyed the recognition and credibility of infant's organic cotton apparel and examined the current quality of children's organic cotton clothes available in the market. This study contributes to improve fabric certification programs and safety standards by understanding customer opinions and actual quality. A customer survey revealed that customers believe that organic cotton products should not include chemicals such as pesticides, fluorescent whitening agents and chemical colors; in addition, customers have high expectations for safety as well as worries about the products' validity. Children's underwear was the most purchased item category among organic cotton products. Current organic cotton certification programs are voluntary with multiple organizations that provide various certification standards. A total of 34.2% of children's organic cotton clothes sold at online and offline stores were not certified, and 10.5% had invalid certification information. This may substantially lower the credibility of organic cotton products and requires immediate change. Examination of organic cotton products showed that products do not meet customer expectations for quality and safety: 3 out of 8 products used accessories (buttons and wappens) that include harmful chemicals such as lead, phthalate and formaldehyde, 6 products used fluorescent whitening agents, and 4 products used other fabrics such as rayon, polyurethane and polyester. GOTS mark is the most recognized organic certification, but it still allows the usage of fluorescent whitening agents, which indicates a gap between customer opinions and actual certification standards. Managing national-level mandatory certification programs like food and setting quality standards that meets customer expectations are required to enhance the credibility of organic cotton products.
