This study investigated verbal and physical interactions which appeared in collaborative science concept learning using augmented reality. Twelve 10th grade students participated in this study. After being organized into three four-member small groups, they participated in classes using smart device-based augmented reality application developed for the understanding of the chemical bonding concept. Their class activities were audio- and video-taped. Semi-structured interviews were also conducted. The results revealed that within individual statement units of verbal interaction, the proportions of information question/explanation and direction question/explanation were found to be high. Within interaction units, the proportions of reformative and cumulative interaction were relatively high. The proportions of progress were also found to be high within both individual statement units and interaction units of verbal interaction. Students' physical interactions were mainly conducted without meaningful verbal interactions. When their physical interactions were accompanied by knowledge construction-related verbal interactions, the proportions of gazing virtual objects and worksheet-related interactions were high. In contrast, various exploratory activities related to the manipulation of markers mainly appeared when they conducted physical interactions only, or when their physical interactions were accompanied by management-related verbal interactions. On the bases of the results, effective methods for collaborative concept learning using augmented reality in science education are discussed.

In this study, we investigated science teacher's guidance of teaching practice in the perspective of the CHAT. Two science teachers working for schools affiliated with a college of education in Seoul took part in this study. Visiting the entire teaching practice, we observed the processes of guidance and the lessons and collected related materials. Semi-structured interviews were also conducted before, during and after teaching practice. All the data were analyzed by using the constant comparative method. The analyses of the results revealed that student guidance during the lessons was also important. And the curriculum orientation needed to be carried out before teaching practice. The division of labor with pre-service teachers relieved teachers of work burden. Teachers failed to guide assessment of students due to influences of community element such as students who were sensitive to grades. In both cases, teaching practice were so collaborative that those were valuable not only for pre-service teachers but also for teachers and students. Two teachers' activity system showed contradictions due to the lack of specific manuals for guidance and the lack of understanding of pre-service teachers. These contradictions brought about difficulties in their guidance, which in turn led to the difficulties experienced by pre-service teachers during teaching practice. They attempted to resolve contradictions in alternative ways and required standardized manuals for guidance, environments in which teachers could collaborate, and close connections with a college of education. Based on the results, we suggest some ways to improve teaching practice.

The purpose of this study was to identify the prevalence of urinary incontinence of community residing climacteric women, and to identify the relationship between urinary incontinence and quality of life. The subjects of this study were 156 women(45 to 59 years old). Data was collected from Sep. 1 to Dec. 1 2002 by an interview or self-reporting by a structured questionnaire. The questionnaire was composed of items of general characteristics, urinary characteristics, and conditions of urinary incontinence, using the modified Henderickson's stress incontinence scale(1981), and the quality of life scale developed by RO, You Ja(1988). The data was analyzed by the SPSS/WIN program using descriptive statistics, Pearson correlation coefficients, t-test and AVOVA. The results of the study were as follows : 1. The prevalence of urinary incontinence was 76.3%. Of the incontinent women, 42.0% had experienced urinary incontinence for a period of one to three years. Frequency of urinary incontinence was once or twice per day for 42.9% of the urinary incontinent women. Most of the participation with urinary incontinence(91.6%) had mild leakage of urine. In the whole urinary incontinent women, 70.6% had never treated or managed their urinary incontinence. Most of the subjects(79.8%) were mildly incontinent, and the prevalence of moderate and severe urinary incontinence was 20.2%. The mean scores among the items of urinary incontinence, in descending order, were increase of abdominal pressure($1.45{\pm}1.05$), coughing($1.16{\pm}0.93$), and sneezing($1.03{\pm}0.92$). 2. The average score in the level in the quality of life variables was 3.12. The urinary incontinence and quality of life were correlated negatively(r=-0.103, p<0.001). 3. There were statistically significant differences in the score of climacteric woman's self reported quality of life according to : amount of urinary incontinence(F=12.68, P=0.001), duration of urinary incontinence(F=6.97, P=0.009), number of urinary incontinence(F=4.77, P=0.03), existence of urinary incontinence(t=148, P=0.05). In conclusion, this study was a preliminary study to provide nursing practice guidelines for climacteric woman with urinary incontinence. Nurses working with climacteric woman should develop and provide adequate care for the incontinent climacteric subjects. In future research, it is recommended to identify comprehensive factors related to urinary incontinence, including the effective management of urinary incontinence.

In Korea, based on the Revised Law of Occupational Safety and Health a new entity of institution was set up in 1990 to provide occupational health services to SSE in which three sorts of personnel as a team have to be involved. These institutions, in charge of scores to hundreds of workplace area-wide, have been providing occupational health services without payment from employers or employees, and government reimburses through the Occupational Injury Prevention Insurance since 1993. As a service provider, a team is composed of doctors, nurses and industrial hygienists. Undergraduate and postgraduate educations for the SSE occupational health are not specified and the question on the performance of the personnel has been raised. This study was designed to analyze the facilitating factors of and barriers to the performance and its improvement of these personnel. In 1997, the survey was conducted with all 58 institutions. Structured questionnaires were mailed to 200 personnel who were providing the occupational health service for SSE. The response rate was 51.7% for doctors, 58.6% for nurses, and 60.3% for industrial hygienist, respectively. Results are as follows : 1) There is a guideline for occupational service mandated by the government. Under the guideline, the minimum frequency of visiting workplace is assured with six times of doctors, 17 times for nurse and industrial hygienist in a year. There are one doctor for every 200 factories, one nurse and one hygienist for every 100 factories. 2) All respondents have basic qualification for occupational health service. About 16.7%. of doctors are certified in industrial medicine or preventive medicine, and 64.7% of industrial hygienists had first grade certification. Totally 66.7% of personnel have been involved in occupational health for more than one year. 3) As a support system for the performance improvement, 66.3% respond that they have been provided with educational materials, advice related to industrial environment and guidance of MSDS from Korea Industrial Safety Corporation. Most respondents indicate the lack of concern of employers and employees as a main barrier to the improvement of the service. Also they are in the need of the training opportunity more focused on SSE. The Governments policy for SSE is a principal facilitating factor. Training program focused on SSE situation, manpower, technical support, etc. are areas to be improved to have a better occupational health service for SSE in Korea.

Social welfare facilities where provide the socially disadvantaged with proper social services, face financial difficulties. This is because not only of the lack of governmental support, but also of social welfare facilities' lack of skills in developing abundant resources from the private sector. In this context, this study tried to find factors affecting resource mobilization of the social welfare facilities to devise policies in resource development. Mail survey was conducted with the structured questionnaire. Employees in charge of community resource development were asked to answer the questionnaire. The study population were two types of welfare facilities: community welfare centers and residential care facilities. A total of 293 community welfare centers and 632 residential care facilities responded to the survey. The response rate was about 62%. The dependent variable of the study was the amount of resource mobilization in the year 2001 which was measured as the number of donors, the total amount of donation, and estimated amount of gift-in-kind. Three types models were constructed per each welfare facility. Independent variables were selected based on the previous research findings: community environment factor, structural factor, and resource development factor. Multiple regression was utilized to analyze the data. The resource development factor turned out to be significant variable in various models. In the models of donors, the amount of donation, and the amount of gift-in-kind, at least one out of four variables in the resource development factor was significant. Welfare centers which establish the resource development department or hire employees to take care of resource development, and adopt computer software in managing donors, receive more donations than their counterparts. Interestingly, the centers where employees take the responsibility of resource development as well as other responsibilities (dual duty), did not have more resources mobilized than those with no employees for resource development. Using computer software in managing donors turned out to be a significant variable in many models, except for the donor model. In addition, residential care facilities located in urban area have more donors and donations, and among residential facilities those for the elderly, children, and the mentally retarded and those hiring more employees, receive more donations than those for the disabled and those hiring less employees. As for the gift-in-kind model, the centers located in high income area and residential facilities for the elderly, women and mentally retarded receive less gift-in-kind than those for the disabled. Based on the above findings, this study suggested that to mobilize resources the welfare centers as well residential care facilities need to have community resource development department or resource development staffs, and adopt computer software to systematically organize donors.

The aim of this study is to understand the ethical struggles of Child Protective Service(CPS) social workers and to indicate some implications for future studies by conducting research focusing on their ethical dilemmas and decision-making. This study used qualitative methods, in particular the phenomenological approach and 14 in-depth semi-structured interviews with CPS social workers, and were conducted and analyzed using the procedures of Colaizzi(1978). This study looks at the following research questions: 1) What kind of ethical dilemmas do CPS social workers encounter? This means what ethical dilemmas do they directly or indirectly encounter because of policy or system inadequacies and huge caseloads. 2) How do the CPS social workers make decisions when they are faced with ethical dilemmas? Making the best decisions with all of their responsibilities and burdens is the focus of this question. This study suggests the following discussions: First, efforts to emphasize 'ethics' at CPS are needed. Second, proper policies and systems based on the Korean situation are needed so that CPS social workers won't have to face 'needless' ethical dilemmas. Third, an index of ethical problems or ethical codes is necessary because principles are important to those social workers who face ethical dilemmas. Fourth, an ethical committee that protects the CPS social workers by supporting their decisions and being responsible for them is needed. Last, a debriefing system that reduces a CPS social worker's psychological trauma caused by ethical dilemmas should be available.

Background: There has no known epidemiologic survey on the frequency of complementary-alternative medicine (CAM) use in the treatment of adult asthma in Korea. This study examined the current use of CAM by asthma patients in Korea. Methods: One hundred adults with asthma, who had been admitted to Kyunghee university hospital between January 2000 and December 2003, were enrolled in this survey. They received a structured questionnaire interview and a clinical assessment of prevalence and pattern of CAM use. Results: 53% patients had an experience of at least one type of CAM during their asthma management. Users of CAM had more hospital visits than those who had never used CAM($1.46{\pm}0.68$ vs. $2.11{\pm}1.20$, p=0.001). Those in their $50^{th}$ decades had more experience of CAM (80%) than the other age groups. The methods of CAM used by our patients are as follows: Diet/nutritional therapy in 35 patients(69%), herbal therapy in 28 patients(53%), acupuncture in 9 patients(17%), moxa treatment in 6 patients(11%), breathing exercises in 1 patient(2%). Conclusions: More than 50% of patients with bronchial asthma have used CAM. A more detailed and large scaled study will be needed to define the actual status of the use of CAM in the treatment for asthma. Inaddition, further research on the scientific validation of the clinical efficacy of CAM in asthma management should be followed.

The purpose of this study was to investigate the effect of Modified Constraint-Induced Therapy (MCIT) on the effected upper extremity of children with hemiparesis. Four children with hemiparetic upper extremity caused by brain injuries were trained by MCIT for ten weeks. During the same period, all of the subjects were also involved in thirty-minute regular physical therapy and occupational therapy. During the treatment period, the unaffected upper extremities of the subjects were restrained by a specially designed hand splint or a mitten for five hours a day, five days per week. For two hours out of the five-hour restraint period, the affected upper extremities were intensively trained by performing various functional tasks, which were individually structured to emphasize use of the affected arm. A single-subject design with A-B-A reversal was employed in this study. The affected limb motor ability was evaluated by Melbourne Assessment, measuring the time to grasp and release nine pegs, and measuring grasping power. As a consequence of this study, the affected limb motor test scores of all four subjects in the baseline period were improved during the treatment period. Furthermore, the treatment effect was maintained during a one-month follow-up period. The results of this study support the assumption that MCIT is an effective therapeutic method to improve the sensory and motor abilities of hemiparetic children. It also increases the frequency of functional use of the hemiparetic hands of brain-injured children. Based on the results of this study, it can also be assumed that the modified CIT method is especially beneficial to these children by reducing the negative emotional effects of forceful restraint of the unaffected upper extremity. To optimize the functional recovery of the paretic upper extremity by CIT, the restriction period per day should be decided individually, according to the characteristics of the individual.

The purpose of this study were to determine causes of low back pain in bus drivers who usually work in prolonged sitting position and to find the relationship of back pain with general characteristics and work environmental characteristics, stress symptoms, to com맹re lordosis angle of habitual driving posture and resting posture in low back pain group and non-low back pain group, and to use this result as a basis for improvement of work environment and comprehensive rehabilitative management of low back pain. Ninety-eight bus drivers were selected from the membership of an urban transit union in Seoul. These informations were collected from May 1, 1997 to May 25, 1997 by means of structured questionnaires and X-ray findings. These data were analyzed by $x^2$ test, t-test, logistic regression using SAS. The major results were as follows: 1. Of the respondents, 66.3% of bus drivers were found to be experiencing back pain. 2. Of the respondents of low back pain groups, 78.5% reported that major cause of low back pain was due to prolonged sitting. 3. The group with experiences of frequent or continuous vibration had more low back pain (p<0.05). There were no significant differences among other work environmental factors. 4. Average stress score was significantly higher in the group with low back pain than in the group without low back pain (p<0.05). 5. The results of the logistic regression analyses were statistically significant vibration from seat and stress score among the risk factors (p<0.05). 6. Averaged lordosis angle of habitual driving posture was $7.6{\pm}14.9$ degrees in low back pain group, $16.5{\pm}8.7$ degrees in non-low back pain and averaged lordosis angle of resting sitting posture was $10.8{\pm}13.7$ degrees in low back pain, $18.9{\pm}9.6$ degrees in non-low back pain group but the difference in mean lordosis angles of two groups was not statistically significant. The results of this study indicate that professional drivers developed chronicity of low back pain due to unfit seat, poor habitual posture and stress from vibration or other risk factors. Therefore, there is need to improve work environment, i.e. enough resting, to set a seat to support lumbar spine properly and to provide comprehensive rehabilitation program including early diagnosis, proper treatment and education for self help management.

This thesis aims to examine the influences of self-regulatory group counseling on self-regulation and school life satisfaction of the higher grade students in Elementary school. To achieve this aim, the following research questions were posed: First, What kind of influence does the self-regulatory group counseling have on the self- regulation of the higher grade students in Elementary school. Second, What kind of influence does the self-regulatory group counseling have on school life satisfaction scale of the higher grade students in Elementary school. In order to verify these research questions, the self-regulation test and school life satisfaction scale were conducted to both the experimental group and control group in pre-test, next, self-regulatory group counseling was practiced to the experimental group. And finally, a post-test was given to both the experimental group and control group. For this study, 200 students from 6th-grader of S Elementary school located in Incheon were given the self-regulation test and chosen 50 students who received low marks. Then, 50 students were researched into the school life satisfaction scale and chosen 16 students who got average-below score again. It was two matching groups through consideration of their score of the school life satisfaction scale, 8 students were arranged to the experimental group and the rest to the control group. The Self-Regulatory Group Counseling program developed by Eun Hyuck-gi(1999). The program was based on the following three programs: "The development. of the Cognitive-Behavioral Counseling therapy and their reports" by Kim HyeSuk(1996), Group counseling" by Brigman and Early(1991) and the study on the improving program in human relation" by Park KyeongAe(1998). The Self-Regulatory Group Counseling program activity was conducted during 6 weeks. Each session was 60 minutes and it continued for 8 sessions. The data collected to find out a difference in self-regulation and the degree of school life satisfaction between the experimental and control groups were processed by means of SPSSWIN program, and the post-test between both the groups were comparatively analyzed through t-test, a mean difference test. The following conclusions were drawn from the results of this study. First, the self-regulatory group counseling program has obvious effect of improving the self-regulation of the higher grade students in Elementary school. Second, the self-regulatory group counseling program has obvious effect of improving the school life satisfaction of the higher grade students in Elementary school. Particularly, this study shows statistical significance in cognitive facts of the self-regulation and the degrees of satisfaction with general school life, teacher, friend and facilities. Since the self-regulatory group counseling program has positive effects on self-regulation and satisfaction with their school life, It is required to utilize the structured self-regulatory group counseling program in school more widely to help students.
