In this study, photoplethysmography(PPG) was suggested as a way to replace the ankle-brachial index(ABI) in diagnosing PAD. The method using the PPG was presented for the simplification of the PAD diagnosis method which was used before. And the index related to the health condition of the artery from the PPG measured in both big toes of the subjects through the experiment was drawn. The indexes showing the significant relativeness in the Pearson correlation analysis with the ABI were the stiffness index(SI), reflection index(RI); it was confirmed each of them had the correlation coefficient of 0.688, and 0.637 at p < 0.05. The explanation ability of the linear regression equation derived using ABI, SI and RI was 52.5%. The explanation ability of the secondary curve regression equation derived using ABI, squared SI was 54.7%. It is expected to provide patients with significant results and draw the index associated with PAD by measuring PPG easily in the real life instead of the ambulatory care field.

Primary responsibility for the health of the school-age child rests with the parents, but the school should assist the parents in establishing and maintaining the highest possible level of health in each child. The important part of school health program is health education. All kinds of testbooks for elementary school were newly developed from 1982 for the 1st to 3rd grader and from 1983 for the 4th to 6th grader. The purposes of this study were to analyse the newly developed health curriculum in elementary school and to point out the errors in contents or terminology. Data were collected from all kinds of textbooks for elementary school which have been using in 1983. On the bases of these data, the following findings were observed: 1) 22.4 percents of total pages which related to health were from athletic subject. 2) Almost 29 percents of learning experiences suggested from textbooks were explanation and teach-centered. 3) The main subjects of health related contents were preventional management and environmental health. 4) 22 errors were found out, they were 12 for contents itself correction, 6 for terminology correction, 3 for lack of explanation and 1 for expurgation.

For the purpose of carrying out nutrition counseling effectively and efficiently, this study assessed the nutrition counseling practice, perception and nutrition knowledge of elementary school children in Gyeongbuk province. Survey questionnaires were distributed between November 2009 and December 2009 to 100 nutrition counseling experienced children (participants) and 110 nutrition counseling non-experienced children (non-participants) and were completed with nutrition teachers' assistance. According to the survey results, girls and overweight/obese children showed higher tendency of participation in nutrition counseling (p<0.001). Participants who took nutrition counseling according to their own intentions showed satisfaction after counseling on diverse subjects such as obesity, unbalanced diet, and weight control. Particularly, 'lack of counseling session time', 'unfavorable counseling condition' or 'difficult explanation' caused participants unsatisfaction after counseling. Participants usually perceived the meaning of nutrition counseling more correctly than non-participants and showed positive intentions for taking further counseling in the future(p<0.001). Diet good for weight control, good food to fix unbalanced diet and diet good for growing stature were the top three subjects of nutrition counseling chosen by subjects (p<0.001). Participants also showed higher nutrition knowledge scores than non-participants. Therefore, it is critically important to apply nutrition counseling in the proper environment (counseling room, time, teaching materials, etc) to elementary school students to fix healthy food habits. Therefore, nutrition teachers need to be provide professional nutrition counseling skills and knowledge.

The purpose of this study was to measure patient satisfaction with hosptial foodservices, and thereby identify areas for improvement and provides basic data for the introduction of total quality management into hospital foodservice in the Taegu·Kyungpook area. This survey was carried out on 676 hospitalized patients in 11 hospitals with over 200 beds to determine the quality satisfaction with foodservices. The subjects were 62.4% male and 37.6% female. Sixty-two percent of the subjects were over age 40, 46.7% were only educated to middle school or below, 41.8% were hospitalized for 1 - 10 days. Eighty-seven precent of the subjects did not receive any nutrition education. The expectation and perception grid showed that the high expectation to the low perception items were the seasoning of the meals, taste of the meals, and prompt dealings with meal complaints. The quality satisfaction values of all the attributes indicated a minus. The unsatisfied quality attributes were the opportunity to meet with a dietitian, seasoning of the meals, taste of the meals, explanation of the meals, and prompt dealings with meal complaints. Among the demographic characteristics, age, education, length of admission, and experience with nutrition education produced significant differences in the quality satisfaction scores. In conclusion, it would seem to be desirable that hospital foodservice department introduce selective menus, hygiene education for foodservice employees, standard recipes, quality assurance, and increase the meal rounding of dietitians in the patient foodservice.

The purpose of this study is to provide preliminary data for bone disease prevention by examining the correlation between bone mineral density, and lifestyle and nutritional status of female shift workers, at general hospitals with an irregular life cycle. The subjects for this study were 232 female shift workers, over 30 years old, who worked at a general hospital more than 5 years. From the subjects, who understood the purpose of this study and decided to be participated, we measured serum albumin, total brotein, total cholesterol, hematocrit, hemoglobin, calcium, phosphorus from blood test, and obtained bone mineral density. To analyze the effectiveness of the variables for explanation power, we established the studied values as independent variables, bone minral density as a dependent variable. Exercise, the number of drinking, calcium, and phosphorus were selected as significant variables and the explanation power was 10.2%. The bone mineral density were significantly higher at the subjects who had exercise, higher calcium and phosphorus possession, and drank alcohol than the opposite cases. Regular exercise, and 1:1 intake of calcium and phosphorous were important to prevent osteoporosis for the subjects who were working three shifts which cause irregular lifestyle.

Because of unpredictability and high possibility of abnormal results by clinical trials compared to general medical behaviors, a procedure for ensuring with sufficient explanations by investigators must be secured. Therefore, in a sequence of clinical trials, what kinds of scope, stage, and method of explanations provided by investigators, including doctors or researchers, to trial subjects are closely related to the compensation for damages by violation of liability for explanation. In case of application of clinical trials to patients who have critical illness such as cancer, issues of "Quality of Life" regarding trial subjects, cancer patients, should be discussed. Especially, in case of clinical trials for terminal cancer patients, the right of subjects' self-determination, which is a fundamental principle in medical behaviors, should be discussed. The right of self-determination includes participation in clinical trials for the possibility of life-sustaining even a little bit, or no participation in clinical trials in order to have a time for completing the rest of his life. Like this, if the extent and scope of explanations related to the issues of "Quality of Life" are raised as main issues, the evaluation of "Quality of Life", should be a prerequisite. In many occasions, realistically, despite bad results such as deaths or serious adverse drug reactions after clinical trials, it may not be easy for compensating to trial subjects or their survivors, who requested civil compensation for damage. Futhermore, in abnormal results after concealment of clinical trials or performance of clinical trials without permission, and in the case of trial subjects' failures of proving proximate cause between the clinical trials and abnormal results, problematic results such as no protection to the trial subjects could be occurred. In performing clinical trials, investigators should provide sufficient explanations for trial subjects and secure voluntary informed consents from the trial subjects. Therefore, clinical trials without trial subjects' permissions and the informed consent process violate trial subjects' rights of self-determination, and the investigators shall be liable for compensation for damages. Then, issues might be addressed are what are essential contents of patients' "rights of self-determination" infringed by clinical trials without subjects' permissions. Two perspectives about patients' rights of self-determination might be considered. One perspective regards physical distress of patients (subjects) from therapies without sufficient explanations as the crux of the matter. The other perspective regards infringement of human dignity caused by being subjects without permission as the crux of the matter irrespective of risks' big and small influences. This research follows perspective of the latter. Forming constant fiduciary relation between investigators (doctors) and subjects (patients) pursuant medical contracts, and in accordance with this fiduciary relation, subjects, who are patients, have expectations of explanations and treatments by the best ways. If doctors and patients set this forth as a premise, doctors should assume civil liability when doctors infringe patients' expectations.

The purpose of this study is to investigate the effects of happiness of early childhood teachers on ego resilience and job engagement. The study subjects were 243 teachers who were working in early childhood education institutes located in K and D area. The collected data were analyzed through descriptive statistics, correlation analysis, and regression analysis using SPSS 18.0 Program. The study results are as follows. First, it was identified that the level of happiness, ego resilience, and job engagement of early childhood teachers were high. Secondly, happiness, ego resilience, and job engagement of early childhood teachers had a statistically significant correlation. Thirdly, the explanation power of happiness for ego resilience was 18% and self-acceptance, a subfactor of ego resilience, had an effect. Also, the explanation power of happiness for job engagement of early childhood teacher was vitality of 23%, and it was found to affect the subfactors of vitality of job engagement in the order of self-acceptance, positive personal relationship, and control over the environment. Also, the explanation power of happiness factors for undivided attention of early childhood teacher was 17%, and self-acceptance and positive personal relationship had a significantly positive effect on the undivided attention of teachers. Lastly, the explanation power of happiness factors for absorption of early childhood teacher was 14%, and self-acceptance among happiness factors of teachers had a significantly positive effect on the undivided attention of teachers. These study results suggest that the quality of early childhood education and happiness should be improved for the early childhood teachers and this may be a positive factor for the improvement of ego resilience and job engagement.

The purpose of this study was to investigate explanations of science textbooks and science teachers' conceptions related to freezing point depression phenomenon. Seven kinds of middle school science textbooks and five kinds of high school chemistryII textbooks were analyzed for the purpose. The teachers' conceptions were searched by a questionnaire developed in this study. The subjects were 146 science teachers. The explanation types of science textbooks were divided into two; 'Description of the phenomenon' and 'Vapor pressure lowering'. The explanations in most of middle school science textbooks and high school chemistryII textbooks belong to 'Description of the phenomenon' and there was no explanation of the reason. The graphs related to depression of freezing point were diverse, too. Most of the science teachers also did not have scientific conception. The percentage of the teachers who thought that the cause of freezing point depression was blocking of solute in solution was high. But the teacher could not find meaningful relation the 'Blocking of solute' explanation represented for elevation of boiling point with depression of freezing point. It is insisted that entropy concept is need to explain depression of freezing point phenomenon in this study.
