This study focused on individual health education for people with hypertension who were being seen in public health centers. The program was an adjusted intervention program that considered the characteristics of each individual and reflected the individual's will to change. Each individual had a different lifestyle with different characteristics and habits so the study considered these individual's characteristics. A comparison was done of knowledge related to hypertension, self-efficacy, and self-care in these individuals. In order to determine the effectiveness of education given by the nurses the variables were measured before and after the individual health education program. The participants in this study were 85 people with hypertension who were seen at a public health center in G city. They were assigned to an experimental group (43) and a control group (42). A tool developed by Park Young-Im (1994) was used to measure knowledge related to hypertension and self-efficacy. A tool developed by Lee Young-Whee (1994) was used for self-care. Data collection was done for 10 weeks from March 24 to May 31, 2003 using interviews with questionnaires. The following is a summary of the results of the study. Hypothesis 1, 'the experimental group which had the individual health education will have higher knowledge scores on hypertension than the control group that did not have the individual health education' was supported (t=4.17, P=0.00). Hypothesis 2, 'the experimental group which had the individual health education will have higher self-efficacy scores than the control group that did not have the individual health education' was supported (t=4.06, P=0.00). Hypothesis 3, 'the experimental group which had the individual health education will have better self-care ability than the control group that did not have the individual health education' was supported (t=4.94, P=0.00). Based on the results of this study, the public health centers should develop an educational program that uses a variety of visual aids and assess the effects of the education on patients with different chronic diseases. After the development of an inclusive education program which will standardize health education effectively and provide a variety of teaching methods, study is needed to measure changes in lifestyle after education and to determine how much knowledge related to hypertension, self-efficacy, and self-care increase

This study aimed to examine the effects of argument-based chemistry laboratory investigations using the Science Writing Heuristic (SWH) approach on students' use and embedding of multimodal representations in summary writing. Participants of this study were thirty-nine freshman students majoring in science education at a National University in Korea. Argument-based chemistry laboratory investigations using the SWH approach were implemented for twenty-three students enrolled in one cohort, and the traditional chemistry laboratory teaching was implemented for 16 students enrolled in the other cohort. Summary writing samples were collected from students before and after the implementation. Summary writing samples produced by students were examined using an analysis framework for examining the use and embeddedness of multimodal representations. Summary writing was categorized into one of verbal mode, symbolic mode, and visual mode. With regard to the embedding of multi-modal representations, summary writing samples were analyzed in terms of 'constructing understanding,' 'integrating multiple modes,' 'providing valid claims and evidence,' and 'representing multiple modes.' Data analysis shows that the students of the SWH group were better at utilizing and embedding multimodal representations in summary writing as they provided evidence supporting their claims. This study provides important implications on pre-service science teacher education.

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.

Abstract Monitoring is the most critical element in implementing "forest carbon offset project" to enhance the visibility of CSR (Corporate Social Responsibility) in North Korea. This study is intended to explore monitoring potential in terms of forest carbon offset project using satellite image for Baekdu mountain of North Korea. The permanent record of standard satellite remote sensing system demonstrated its capability of presenting area-wide visual evidences of monitoring conditions in Mt. Baekdu mountain of North Korea (site suitability, carbon stock by forest biomass growth, carbon emission by forest biomass loss, deforestation and degradation, environmental, social and economic impact specified in the Carbon Sequestration Law). It doesn't seem very difficult to comply with monitoring requirements for "the forest carbon offset project" due to the probative value of satellite data. Therefore, it could be considerable or realistic approach to utilize CSR based forest carbon offset project as a point of reform and open-door in North Korea. It is anticipated that this research output could be used as a valuable reference for Korea-based enterprises to ensure monitoring potentials using satellite image in exploring forest carbon offset project sites in North Korea.

In this paper, we propose the chromatic adaptation models (CAM) for the variations of the luminance levels. A chromatic adaptation model, CAM$\Delta$Y , is proposed according to the change of luminance level under the same illuminants. The proposed model is obtained by the transform the test colors of the high luminance into the corresponding colors of the low luminance. In the proposed model, the optimal coefficients are obtained from the corresponding colors data of the Breneman's experiments. In the experimental results, we confined that the chromaticity errors, $\Delta$u'v', between the predicted colors by the proposed model and the corresponding colors of the Breneman's experiments are 0.004 in u'v' chromaticity coordinates. The prediction performance of the proposed model is excellent because this error is the threshold value that two adjacent color patches can be distinguished. Additionally, we also propose equal-whiteness CCT curves (EWCs) by CAM$\Delta$Y according to the luminance levels of the surround viewing conditions. And the proposed EWCs can be used as the theoretical standard which determines the reference white of the color display devices.

Background : To demonstrate the efficacy of moxibustion therapy, randomized controled trials are required. But, clinical trials of moxibustion had limitations due to the absence of a sham moxibustion model for an appropriate placebo. Objectives : To develop a new sham moxibustion model based on the thermal characteristics of commercial indirect moxibustion, especially temperature, and to evaluate whether it could be applied in clinical trials. Methods : By applying heat insulation, we created a sham moxibustion device that was indistinguishable from a real one with the naked eye. It also stimulated heat but had inert remedial value. A clinical trial was performed on subjects to test double blinding. The subjects were randomly assigned into two groups, a treatment group and a sham group. Acupoint Zusanli($ST_{36}$) was used in each group for 3 times. A sham acupuncture credibility questionnaire was modified into a moxibustion credibility questionnaire and was filled out after treatment. Results : No major difference was detected in the subjects' baseline data. Most subjects and practitioners could not distinguish the sham moxibustion device from the real one. But, subjects who had experience of moxibustion therapy more likely to distinguish the sham moxibustion device from the real one than subjects who didn't have experience of moxibustion therapy. The treatment group showed a significant difference in the VAS(Visual Analog Scale) for intensity of sensation during treatment than that of the sham group. Conclusions : The sham moxibustion device in this study is proved sufficient and credible to be applied in investigations of the effect of moxibustion. But it is more appropriate for the people who don't have experience of moxibustion therapy.

Objectives : The purpose of this study is to investigate the correlation between acupuncture therapy on knee osteoarthritis and BMI. Methods : Data on assessment measurements of knee osteoarthritis and obesity were obtained from 31 patients suffering from knee osteoarthritis from May, 2011 to September, 2012. The assesment measurements consisted of body mass index(BMI), visual analogue scale(VAS) and Western Ontario and McMaster Universities(WOMAC) index. Statistical correlations among assessment measurements were evaluated by examining the Pearson's correlation coefficients. Results : 1. The average age of all patients was $58.87{\pm}9.48$(male : $63.67{\pm}11.34$, female : $57.72{\pm}8.86$). 2. The average BMI of all patients was $25.41{\pm}3.06kg/m^2$. According to clinical definition of obesity by Korean Society for the Study of Obesity, 25.81% of all patients was within normal weight, 25.81% was overweight, 38.71% was obesity and 9.67% was morbid obesity. 3. There were no significant correlations in statistics among assessment measurements. Conclusions : There is significant correlation between knee osteoarthritis and obesity according to many clinical and experimental researches. So more studies on correlation between knee osteoarthritis and obesity and development of assessment measurement are needed.

Purpose: This study was designed to evaluate the comparison between the subjective and the objective evaluation of pain control effect in masticatory muscle pain depending on time and dose change. Methods: The patients were recruited to this study and diagnosed according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Experimental group were divided into three groups; saline injection group (n=10), morphine 1.5 mg injection group (n=10), and morphine 3.0 mg injection group (n=10). Evaluation list was the subjective pain evaluation (visual analogue scale, McGill pain questionnaire) and the objective pain evaluation (pressure pain threshold [PPT], pressure pain tolerance [PTO]). The subjective and the objective pain evaluation were performed at the times of just before injection, 10 minutes, 30 minutes, 1 hour, 24 hours, and 48 hours after injection. Then, data were statistically analyzed. Results: The results were as follows: 1) There is no statistically significant difference between the results of the subjective and the objective pain evaluation with regard to the short-term (within 1 hour) analgesic effect of morphine sulfate. 2) However, after 1 hour of injection, while the subjective pain evaluation score still decreased, the objective pain evaluation didn't show significant changes in PPT and PTO (1 hour, p<0.05; 24 hours, p<0.01; 48 hours, p<0.001). 3) In comparison to changes in the dose, the McGill pain questionnaire was the most statistically effective method among the subjective pain evaluations (1.5 mg, p<0.05; 3 mg, p<0.01). Conclusions: Therefore, it was revealed that the subjective pain evaluation was more effective to evaluate long-term pain control, and that the McGill pain questionnaire could be an effective way to evaluate pain control depending on dose changes. It requires further investigations with time and dose extension.

Summary of Background Data: Myofascial pain syndrome (MPS) is a common painful muscle disorder caused by trigger points occurring in myofascial. MPS is a major cause of chronical pain and is the subject of further clinical examination. Purpose: To uncover effective intramuscular stimulation therapy (IMS), the patients' actively participation stretching exercise and stabilizing around shoulder girdle where trigger point provoking myofascial pain syndrome in usually occurred. Methods: 45 myofascial pain syndrome patients were randomly chosen and divided into 3 groups. The first group (G1) received only IMS therapy, The second group (G2) had both IMS and active stretching exercises administered and the final group (G3) was given IMS therapy and stabilizing exercises. Therapy intervention was given for 3 weeks, 3 times a week and then only stretching exercise for the second group and stabilizing exercise for the third group was given for another 3 weeks. The visual analogue scale was dine before the experiment, 3 weeks after the experiment and 6weeks after the experiment to measure subjective degrees of pain and pressure pain threshold to measure sensitivity improvement of trigger point and functional ability questionnaire to measure daily life performance. Results: There were no significant changes after 3 weeks but after 6 weeks, between GI and G2 and between G1 and G3 showed significant change of pain, pressure pain threshold and daily life performance. There were significant improvement of the measurement of degrees of pain, pressure pain threshold and improvement of daily life performance at different times for G1 showed change 3 weeks after the experiment, but there were no changes 6 weeks after the experiment. There were significant improvement of the measurement at different times for G2 and G3 showed change 3 weeks after the experiment and 6 weeks after the experiment. Conclusions: IMS therapy proved to be effective in inactivation of trigger points of the myofascial pain syndrome patients and stretching and stabilizing exercises beside it keep remedial value longer by improvement of pain and dysfunction that occurred by the trigger point.
