The purpose of this study is to analyze the relationship between life style and health status of the staffs of an elementary school to understand exercise practices and life styles and to analyze the self-efficacy and the factors that affect it concerning walking exercise. The subjects were m9 staff member of the 10 elementary school in Seoul and materials were collected through an organized examination table from October, 1999 to May 2000. The people health awareness table was used as a variable for life style, the 13 questionnaires made of a 5 points measure was for the self efficacy concerning walking exercise. The data was analyzed through a statistics package made of a Chisquare-test, t-test, ANOVA and a regression analysis. The major results of this study were as follows; 1) 50% of the staffs were practicing regular exercise, 3/4 of them practiced walking, jogging and mountain climbing that don't need equipment and exercise frequency was 1-2 times per week 64%. of the time and exercise span was under 30 minutes in 38%, the highest 2) The average of self-efficacy concerning walking exercise was 3.6 points but the answers "I can walk enough to be in a sweat", "I can walk according to my exercise plan" were relatively low. 3) The explanation degree of the Model was 14% in a regression analysis between self efficacy concerning walking exercise and as a dependent variable for a regular walking exercise plan, regular health examination, routine health status, and breakfast might serve as an explanation degree. According to the results of this study, the suggestions were as follows: 1) The chronic invalid was not enough in the change of life style after chronic disease, most of all, it need the awareness of change, of active health education and of public information for health promotion action practice through the prohibition of smoking, abstinence from drink, exercise and nutritional balance. 2) Concrete practice program enlargement is needed to enhance related walking exercise or of a type lecture meeting for subjects who have a positive attitude about walking exercise plans. 3) A program that can actively recommend a health promotion life style is needed when we make allowance for those who have an ordinarily healthy life style and show a high walking exercise self-efficacy.

Objectives. This study was carried out to analyze the hearingthreshold levels and relating factors of 1,048 workers with noiseinduced hearing loss$(D_1)$. Methods. We analyzed the hearing-threshold levels and relating factors of 1,048 workers with noise-induced hearing loss$(D_1)$ examined by the summary reports of specific health examination results of industries and personal reports of specific health examination results reported by 58 specific health examination institutes and 8 secondary pneumoconiosis examination institutes in 1996. Results. Among 1,048 workers at 510 workplaces, male workers were 1,009 (96.3%) and female workers were 39 (3.7%). The mean ages of workers initially exposed to noise and at present were 28.7 and 47.2, respectively. The duration of total exposure was 16.5 years. Average hearing-threshold levels analyzed by three-divided classification of the study subjects were 43.7dB(Lt) and 42.6dB(Rt). Those analyzed by six-divided classification were 50.5dB(Lt) and 48.6d8(Rt). Among workers with noise-induced shearing loss$(D_1)$, 16.3% was unilateral hearing loss and 84.6% was classified to compensation case. 8.8%(Rt) and 10.2%(Lt) of them were suspected to be conductive hearing loss by differences of air-bone hearing-threshold levels. Hearing-threshold levels of workers in manufacturing industry were significantly increased during the short exposure compared with the levels in mining industry. Among manufacturing industries, hearing-threshold levels of workers in trailer and other transportation equipment manufacturing industry were significantly increased. Age and duration of total noise exposure were not significantly related to the average hearing-threshold levels analyzed by three-divided classification. Hearing-threshold levels of female workers were significantly increased during the short exposure compared with those of male workers. Hearing-threshold levels of workers at the high risk group, ages of 20s, 30s and total exposure duration of less than 10 years, were not significantly increased compared with those of the other groups. However, they were exposed at young ages. The 3 leading industries of workers at high risk group were trailer and other transportation equipment manufacturing, automobile manufacturing and assemble-metal manufacturing industries. Conclusions. This study was the first nationwide analysis of the hearing-threshold levels and relating factors of workers with noise. induced hearing loss$(D_1)$. We found the differences of the real number by the statistics of the department of labour and the expected number of worker' s compensations for occupationally-induced hearing loss estimated by this study. According to the results of this study, we should carefully examine the methods to narrow this difference.

Objectives. The Study of Small Area Variation(SAV) is most interesting issue in the health care researches. Most studies of SAV have been concluded the existences of variation on the basis of the magnitude of variation without statistical testing. But it is difficult to explain the existence of variation with this way because variation indicies are easily influenced by several parameters and also their distribution are skewed. So, it needs for the study to investigate the distribution of these indices and develop the statistical testing model. Methods. This study was planned to analyze on the distribution of variation indices such as Extremal Quotient(EQ), Coefficient of Variation(CV), Systematic Component of Variation(SCV) and compare the statistical power among indicies. The simulations was performed on the basis of several assumptions and compared to the empirical data. Results. Main findings can be summarized as follows. 1. If other conditions are constant, the more number of regions, the larger 95 percentile of EQ. But under same situation, 95 percentile of CV and SCV were slightly decreased. 2. If the size of regional population or utilization rate were increased, 95 percentile of all statistics were decreased. Also in the cases of small population size and low utilization rate, 95 percentiles of EQ showed various change contrast to the little change of CV. 3. If the difference at the size of regional population were increased, 95 percentiles of EQ and SCV were increased contrast to the little different of CV. 4. If the utilization rate were increased, 95 percentiles of all indicies were increased. But under the same difference of utilization rate, the power of CV and SCV were increased comparing to no change of the power of EQ. 5. Usually the power of EQ were lower than that of CV or SCV and it is similar between CV and SCV. Conclusions. Therefore, we suggest that in selecting the variation indicies at the SAV, CV or SCV are superior than EQ in terms of significance level and power.

The study was intended to identify the nurses' experiences, understanding, and attitudes on DNR. Also, the study was to provide the data base for a standard of DNR decision-making and practice. The sample consisted of 347 nurses in eight general hospitals. The data were collected between August 1 and August 31, 2000. The data were analyzed using descriptive statistics and $x^2-test$. The results of the study were as follows : 1. Regarding DNR-related experience, 74.6 percent of the participants experienced DNR situations. Eleven percent of the participants received DNR education. DNR was most frequently (81.5%) requested by family members and relatives of patients. The decision-making on DNR was most frequently (76.8%) made by agreement between family members and medical staff. The DNR order was recorded at 81.9 percent on charts. Problems after DNR order were negligence in treatment and nursing care (30.6%) and guilty feelings due to doing the best (22.1%). CPR (cardiopulmonary resuscitation) was performed about 49.8 percent of DNR cases. 2. Regarding understanding and attitude on DNR, most of the participants (93.1%) thought DNR was necessary. The major reasons for the necessity of DNR were impossible recovery (44.4%) and death with dignity (41.1%). The decision-making on DNR was most frequently made by patient and family members (47.8%) and followed by agreement between family members and medical staff (25.6%), and patients themselves (16.4%). Most of the participants thought that medical staff must explain DNR to critical and end-of-life patients and their family members. Forty four percent of the participants thought that the most appropriate time for DNR explanation was when patients with critical disease were admitted to hospitals. Most of the participants (90.2%) thought a guide book for DNR is necessary to be made in hospitals. 3. There were significant differences in the participants' understanding and attitudes on DNR according to religion career education and experience of DNR. Of the participants those who have religions and education experience on DNR thought that there would be more DNR requests after DNR is explained to patients and family members (p<.05). In addition, there was higher understanding on the necessity of DNR in those who have more career and DNR experience(p<.01). The findings of the study suggest that a guide book for DNR need to be made with inclusion of legal, ethical, and cultural aspects. Also, there needs to be more education on DNR in medical ethics to health care professional and to provide more information on DNR to the general public.

Objective : The purpose of the study is to investigate and compare multi-cultural families in terms of mother' s attitude on child-rearing and their children's sensory processing ability. Methods : 19 multi-cultural families and 38 ordinary families were investigated and all the targeted families had children aged 3 to 7 years. Data were collected by a questionnaire asking general characteristics of mother-child; mother's attitude on rearing; and child's sensory processing ability, the Korean-translated version of Short Sensory Profile [SSP], and the Mother nurturing attitude. Data analysis has been done by Descriptive Statistics for subject characteristics and by Mean-Whitney U test for comparison between multi-cultural family group and ordinary family group. Results : There are significant differences between the two family groups in terms of the rearing attitude, especially in sub-item 'refusing(p=.000)'and 'autonomous(p=.000)'. Result of the SSP also indicate significant differences between the two groups in total score(p=.002) and sub-items such as taste/smell sensitivity(p=.004), movement sensitivity(p=.021), underresponsive/seeks sensation(p=.010), auditory filtering(p=.016), low energy/weak(p=.003), visual/auditory sensitivity(p=.029). Conclusion : The results of this study well describe differences between multi-cultural families and ordinary families in maternal child-rearing attitude and sensory processing ability of the children. It is suggested to collect data regarding adaptation of multi-cultural families and their child development through more profound qualitative studies in further.

Objectives: Using as a sleep evaluation tool the Pittsburgh Sleep Quality Index (PSQI), this paper studied the effects of earthing on the amount and quality of sleep by examining a patient population of people who used and did not use earthing mats and a group of general healthy people. Methods: From September to November 2019, 30 patients who voluntarily used an earthing mat, 40 patients who did not use an earthing mat, and 40 healthy people who did not use an earthing mat were selected. A questionnaire applying the PSQI (Pittsburgh Sleep Quality Index) after being translated into Korean was distributed starting November 29, 2019 to 110 subjects. Out of them, 101 subjects who completed the questionnaire were examined. All statistics used SPSS 25.0. Results: The first overall score showed that all three groups had problems sleeping, with five points or more, but the general population had better sleep quality than the patient group. It also showed that the using matgroup had better quality of sleep than the ones that did not use the earthing mat In addition, the analysis of the third group through the variance analysis showed significance at >0.05 for the general population and the patient group. Based on this, a multi-comparison analysis of the third group showed significantly less than 0.05 in patients who do not use an earthing mat compared to the public. First of all, there are no statistically significant differences between the three groups in subjective sleep quality, sleep latency, and sleep time, but an analysis of multiple comparison analysis with the general population group showed that the quality of sleep was worse compared to those that used the mat. In addition, sleep efficiency, sleep disorder, sleeping pills, and daytime dysfunction were found to be less than >0.05 in the three groups. Conclusions: These results suggest that if you ground your body to Earth during sleep, the secretion of cortisol will decrease night levels, sync more with the natural 24-hour circulation rhythm profile, and that when you sleep, sleep is better and pain and stress are associated with the study. While the preceding study cannot confirm that contact with the ground affects the quality of sleep, it suggests that it is relevant as shown in this paper.

Objectives: The purpose of this study is to identify the status and opinions of professional oral health care performance in oral cancer patients. Methods: Seven National University Dental Hospitals and the National Cancer Center in Korea surveyed the medical personnel in charge of oral health care for oral cancer patients. The questionnaire consisted of 16 questions, including the status of expert oral health care education and performance for oral cancer patients, etc. A total of 47 questionnaires were retrieved, and the collected data were used in PASW Statistics 23.0 to perform frequency analysis, cross-analysis, and kruskal Wallis tests. Results: A survey of oral health care education found that 29.8% of the medical personnel had received education. The most performed of professional oral health care was found that applying fluoride by dental hygienist, treating stomatitis by dentist, and wiping mouths with sponge by nurse. The assessment of self-performance has shown that applying fluoride by dental hygienists has a statistically significant difference. Only 37.8% of oral health care education for patients was conducted. Most recognized that oral health care in oral cancer patients was important, but it is difficult to provide care due to lack of performance personnel and time, opportunities for performance personnel to be educated. The improvement was found to require an increase in the number of performance personnel, placement of professionals, and practical training to enhance performance capabilities. Conclusions: For oral health care of oral cancer patients, continuous education for medical personnel, establishment of oral health care manual and medical system, research on oral health care of oral cancer patients and public relations campaign will have to be activated. Development of expert care manual analysis and evaluation tools for oral health care in oral cancer patients in the future and development of standardized curriculum will be necessary.

KFDA compiles the statistical data of food poisoning outbreaks two or more persons since 2002 in Korea and release them to the public on the web. There is a gap of outbreak number between the real situation and the reports. To reduce the gap, addition of sporadic individual case of food poisoning may be one of the solution method. The statistical data of Japan where food consumption pattern is similar to Korea, were used in this study to compare the ratio and the pattern between the outbreak cases two or more persons and individual cases. By doing so, the data of Japan regarding to outbreak cases two or more persons will be comparable to that of Korea. The data of 2002 and 2003 in Japan showed that sporadic individual cases were 43.3% in the total food poisoning cases. The individual cases occurred highly in unknown places (90-92.3%) and home (6.2-8.5%) whileas the outbreaks two or more persons occurred mostly in the place of restaurants (46.6-50.l%) and inns (9.2-9.8%). The food-borne pathogens attributed to the individual cases were C. jejuni (51.9%), Salmonella spp. (35.3%), and V. parahaemolyticus (9.8%) while those to the outbreak cases two or more persons were norovirus (31.3%), Salmonella spp. (20.8%), C. jejuni (15.5%) in Japan. The data of 2002-2009 between Korea and Japan showed the outbreak case report rate was 1:1.5 based on the total population number.

As the number of vehicles has been sharply increases, the significance of safety and effective operation issues in the parking lot is being emphasized, which takes a part of the transportation system. Recently, there have been several studies for the parking management by detecting moving object, however, recognizing numbers of fast-moving vehicles simultaneously in the picture is still a challenging problem. The parking lot in public area, or large-sized buildings has clear parking section, whereas the sensor system is configured to monitor a plurality of parking spaces. Therefore, by considering those parking lots, we suggested to develop the real-time parking availability information system by applying the real-time image processing techniques. with the help of template matching. Following the study, we wanted to provide the alternative method for parking management system through the reference template makers by recognizing movements of parked vehicles with the size and shape, regardless of direct detecting of driving movements. In addition, we evaluated the applicability and performances of the information system, presented in this study, and implemented a prototype system to simulate the parking statuses of each floor. In fat, it was possible to manage and analyze statistics about the total number of parking spaces and the number of vehicles parked through real-time video flames. We expected that the result of the study will be advanced, following the user-friendliness and cost reduction in operating parking management system and giving information by efficient analysis of parking situation.
