The purpose of this study was based on students in high school to find out how interest eating and controlling weight on normal time by sex to let them get a better sense's of view on weight controlling so they can get healthy, and healthy school life and concentrate on studying, As a result of analyzing the data collected for the subject of high school students, the conclusions were as follows; First, out of 325 students, 44.6% were male students, and 179 were female students, Compared to the BMI, normal mass were 50.8%, which were 165 students, less weighted were 39.7%, which were 129 students, and over weighted were 9.5%, which were 31 student. Also average height for male students were 173.8 cm, for female students were 161.5 cm, average weight were 67.2 kg for male students, and for female students were 53.2kg. Using BMI analysing the results and the male students had an average of 22.2%, and the female students had an average of 20.3%, so male students were a little higher than the female students. Second, the interest rate for weight control were 82.2%, that's 267 students for, 'interested' and 7.8%, which were 58 student for 'not interested', so most students were interested, in controlling weight. Interest rate were 83.6% for male students, 81.0% were female students. BMI told that group of less weighted were 82.9%, group of normal were 79.4% and group of over weighted were 93.5%. The rate were all high not relating to BMI. Third, compared to the past, more people said 'normal'(41.3%), people who said 'a little fat'(36.3%) decreased, but they still think they are fat even though they are not, also when they are less weighted they still think they are fat. Fourth, for 'weight control, and food' both male and female said they were related, and for 'weight control and exercising' they also said they were related, but more male said that they were related, However for relations between' controlling weight and school's physical education class' the answers were usually disagree. Fifth, for the 'satisfaction of their present weight', both BMI and the students answered and this results were mostly same as the past result, so most students prefer to lose weight. Also, both male and female think that the reason they have this weight now is, because of 'the amount of exercises' and 'the amount of food they eat', so they find that it's related to each other. Sixth, for the experience on weight control, both male and female had experiences, and they answered 'exercising and food treatment' is the good way to control weight. Also for 'the reason they started to control there weight', both male and female answered, 'they thought there weight were not normal'. Seventh, 'Do you pick on food to control weight?' and 'Do you feel nervous before you eat?' and for last 'control of drinking water' the answer was all different, and both male and female answered negatively. Eighth, time wasted on exercising per day, for less than 30 minute were 81.5%, the form of exercises that students did were 'not much or walking on the way to school and way to home'. Usually for their free time, male students spend on exercising however female student did not. Also both female and male students showed that they like to exercise, but majority of female student disliked to exercise. To everyone's point of view 'like'(32.9%), 'like a lot'(20.9%), so everyone agrees. The knowledge information on controlling weight, they answered, usually found from commercials, newspaper or magazines and from parents or friend. From the past many high school students wanted to control their weight, so there should had been a good education on this, however there wasn't any of those education and still it doesn't exist. Also most school's education are arranged to entrance pressure so they have a lot of knowledge and informations to it, but for real they don't have any activity or actions on it. Through this research, we felt that, we should correct students with wrong understanding on controlling weight and wrong knowledge. Also we suggest to make an activity program for this.

Author applied several engineering methodologies to classical ultrasonic nebulizer to cope with it's demerits. After several trials and errors, we got the several meaningful results. To evaluate the modified ultrasonic nebulizer for inhalation toxicology of cadmium, author used light-scattering photometer. This paper is the one part of inhalation exposure systems for inhalation toxicology study of cadmium. According to the testing conditions, source temperature 50℃ and inlet-duct band temperature 150℃, aerosol generation results for sodium chloride and cadmium chloride were as followings: Coefficients of variation(CV) of sodium chloride and cadmium chloride for repeated trials were 3.38 and 4.77 for 10g, 2.47 and 5.02 for 5g, and 4.70 and 2.98 for 2.5g. All the CVs were within 10% of acceptance variability. Count Per Minute(CPM) changes of NaCl and CdCl₂ for 5 repeated trials were similar. CPM ratios of CdCl₂/NaCl were 1.13 for 10g, 0.76 for 5g, and 1.06 for 2.5g. Relative aerosol generation of cadmium chloride to sodium chloride was the highest in 10g. Efficiency increases of 24.50% for 5g NaCl, 14.91 % for 2.5g NaCl, and 16.48% for 2.5g CdCl₂ with respect to theoretical efficiency were observed but 0.04% efficiency decrease was observed in 5g CdC₂. According to the modifications of source temperature(20, 50, 70℃) and inlet-duct band temperature(20, 50, 100, 150, 200℃), aerosol generation results for NaCl and CdCl₂ were as followings: CPM trends for each quantity excepting 10g NaCl in inlet-duct band temperature 200℃ were similar, and the highest CPM was observed in source temperature 70℃ to each inlet-duct band temperature. The highest CPMs to 10, 5, and 2.5g NaCl were observed in source temperature 70℃ and inlet-duct band temperature 20℃. Aerosol generation of cadmium chloride was increased with the higher source temperature, excepting inlet-duct band temperature 200℃. The highest CPMs for 10, 5, and 2.5g CdCl₂ were observed in source temperature 70℃ and inlet-duct band temperature 20℃, and this trend was similar to NaCl aerosol generation The highest CPMs for 10, 5, and 2.5g CdCl₂ were observed in source temperature 70℃ and inlet-duct band temperature 20℃, and this result was similar to NaCl aerosol generation. Observed efficiencies of 5 and 2.5g NaCl were similar to ifs theoretical efficiency but -3.08% efficiency decrease of 5g CdCl₂, 17.47% efficiency increase of 2.5g CdCl₂ were observed. CPM ratio of CdCl₂/NaCl of 10g was different to 5 and 2.5g, and 2.5g ratio was higher than 5g ratio. In conclusion, to get maximum aerosol generation for NaCl and CdCl₂ will be the conditions that set the appropriate inlet-duct band temperature for each materials and increase the source temperature. Sodium chloride can be used to evaluate the performance and predict the concentration for cadmium aerosol in aerosol generator and inhalation exposure system.

Liver transplantation is definitive treatment for the patients suffering from hepatitis, severe liver cirrhosis and liver cancer. In these patients, systemic infections under immunosuppression may occur easily. Therefore, primary object of dental treatments before liver transplantation is absolute removal of oral infection source. In addition, comprehensive dental management plan is essential for success of liver transplantation. The present study has been performed to investigate decayed, missing and filled permanent teeth index(DMFT index), degree of oral hygiene, past medical history, need of dental treatment, completion of dental treatment need and time interval between dental visit and operation date of liver transplantation in liver transplant candidates. Obtained results were as follows; 1. Decayed teeth of the patients were 2.68, missing teeth were 4.02 and filled teeth were 3.42. DMFT index was 10.12. 2. Twenty percents of patients showed moderate to severe food impactions, 42.2% of patients had moderate to heavy calculus and 37.8% of patients displayed gingival inflammation with swelling. 3. Patients needed periodontal treatments more than any other dental treatments. Periodontal treatments were needed for 88.9% of patients, operative & endodontic treatments were 46.7% of patients and 33.3% of patients needed for oral & maxillofacial surgical treatments. 4. Among 90 patients, time interval between scheduled operation date of liver transplantation and dental visit was within 2 weeks for 32.2% of patients, within 1 week for 20.0% of patients. In conclusion, most liver transplant candidates needed dental treatments for removal of potential infection sources. However because of insufficient interval between dental visit and operation date, they had taken liver transplantation procedures without comprehensive dental management. Development of preventive and comprehensive dental management program is mandatory for these patients. Cooperative interdisciplinary management will play a positive role for successful liver transplantation.

The purpose of this study was to examine the sex-consciousness and sexual values of school children by geographic region. It's specifically attempted to make a comparative analysis of sex-consciousness and sexual values between urban and rural elementary schoolers to help provide efficient sex education for them to build the right sexual values. The subjects in this study were 400 elementary schoolers in their sixth year of elementary schools located in Danyang-gun and Chungju city, north Chungcheong province. After a survey was conducted, answer sheets from 387 students that were analyzable were analyzed. For data handling, SPSS program was employed, and t-test was utilized to see if there's any differences between the urban and rural elementary school youngsters in sex consciousness and sexual values. And $x^2$ test was used to make a comparative analysis of their view of sex education. The findings of the study were as follows : First, regarding sex-consciousness, they had general knowledge on sex. Especially, they were highly aware of sexual violence and the generation of baby, but many of them didn't know about where and how egg cells were produced. This indicated that systematic education should be offered in various ways. Concerning geographic gap, there was a significant difference in sexual knowledge between the urban and rural students. As to sexual attitude, they took a relatively positive attitude toward display of affection or sex-related talk on TV or in movies, as they viewed it as natural. This finding implied that the elementary schoolers were recipient toward sex and took an active attitude toward sexual expressions. Concerning geographic gap, there was no difference between the rural and urban students. As for sexual practices, the largest group of the students had a liking for the opposite sex, which showed that their needs for sex were unveiled in the course of having some trouble due to the other sex rather than through firsthand experiences or activities. As to geographic gap, there was a significant difference between the urban and rural students in that regard. Besides, the urban students put their sex-consciousness in practice more often than the rural students did. After they are educated to build the right sexual values, systematic sex-education programs should also be offered for them to be exposed to sustained sex education and to team how to apply their sex-consciousness to real life. Second, as for sexual values, the school children had relatively positive and equalitarian sexual values. Regarding geographic gap, there were significant gaps between the two groups' view of the opposite sex, sexual roles and chastity. Concerning view of the opposite sex, they attached more importance to the inner aspects of the opposite sex than his or her look, and they wanted to date in a natural manner. Regarding sexual roles, they were relatively well cognizant of gender equity and the importance of male and female roles. As to view of chastity, they looked upon sex as natural, not as what's ugly or ashamed of. Third, concerning their outlook on sex education, approximately more than half the students felt the needs for sex education, and there was a significant difference between the urban and rural students. They wanted to receive education about the prevention of sexual violence and physical changes during puberty the most, and there was a significant gap between the urban and rural students in this aspect. As to the time for sex education, they thought that students should start to be exposed to sex education in their fifth or sixth year. This finding signified that fifth or sixth graders who were in the beginning of puberty started to have a lot of interest in their own physical changes. Therefore, sex education would produce better effects when it's provided to fifth or sixth graders. Nearly half them preferred single-gender class when they received sex education, and there's no gap between the urban and rural students in that regard.

This study identifies the terms frequently used together with energy in online science news articles and topics of the news reports to find out how the term energy is used in everyday life and to draw implications for science curriculum and instruction about energy. A total of 2,171 online news articles in science category published by 11 major newspaper companies in Korea for one year from March 1, 2018 were selected by using energy as a search term. As a result of natural language processing, a total of 51,224 sentences consisting of 507,901 words were compiled for analysis. Using the R program, term frequency analysis, semantic network analysis, and structural topic modeling were performed. The results show that the terms with exceptionally high frequencies were technology, research, and development, which reflected the characteristics of news articles that report new findings. On the other hand, terms used more than once per two articles were industry-related terms (industry, product, system, production, market) and terms that were sufficiently expected as energy-related terms such as 'electricity' and 'environment.' Meanwhile, 'sun', 'heat', 'temperature', and 'power generation', which are frequently used in energy-related science classes, also appeared as terms belonging to the highest frequency. From a network analysis, two clusters were found including terms related to industry and technology and terms related to basic science and research. From the analysis of terms paired with energy, it was also found that terms related to the use of energy such as 'energy efficiency,' 'energy saving,' and 'energy consumption' were the most frequently used. Out of 16 topics found, four contexts of energy were drawn including 'high-tech industry,' 'industry,' 'basic science,' and 'environment and health.' The results suggest that the introduction of the concept of energy degradation as a starting point for energy classes can be effective. It also shows the need to introduce high-tech industries or the context of environment and health into energy learning.

This study evaluated the moral sensitivity, self-assertiveness, ethical decision-making confidence and their correlations, and the factors that influence ethical decision-making confidence among nurses working in a long-term care hospital. Overall, 149 nurses working in a long-term care hospital in G Province were evaluated. The date was collected from November 30 2019 to December 18, 2019 and analyzed using SPSS/WIN 21.0 program. The mean of moral sensitivity among nurses was 4.94, the mean of self-assertiveness was 3.17 and the mean of ethical decision-making confidence was 3.49. The self-assertiveness will, according to the general characteristics, was significantly different according to experienced moral distress, and there was a significant difference in the degree of ethical decision-making confidence according to social positions and experience of ethical education. There were positive correlations between the ethical decision-making confidence and moral sensitivity (r=.382, p<.001) and self-assertiveness (r=.224, p<.01). Regression analysis revealed that the factors that significantly influenced ethical decision-making confidence were moral sensitivity, self-assertiveness and ethical education during nursing practice, which explained 25.0% of variance in ethical decision-making confidence. Therefore, to improve ethical decision-making confidence of nurses, programs should be developed that improve moral sensitivity and self-assertiveness by promoting ethical education.

This survey was done to construct a nursing theory according to Korean culture and to identify the Korean traditional view. From ancient time until now, shamanism has played an important role as determinant of Korean culture and of the personality formation of Korean people. The subjects are 321 patients and member of their families who were over 18 years old, and who are living in five large cities and two rural communities in Korea. Data collection was done from March, 8th to April, 29th in 1999. SPSS The tool developed by the investigator through literature review was used to measure the perception and the attitude of patients and their families to Korean shamanism. Collected data were analyzed by frequency, percent and $x^2$ test with SPSS program. The results are summarized as follows ; 1) While 35% of respondents answed that the destiny or fate(八字) was only relied on the abilities and endeavor of individual, 65% of respondents were fatalists(運命論者) or eclectic(折衷主義者) are compromised between the fate and endeavor. 2) While half of the respondents belief in divination(占) to some degree, the rest of them reported hardly any belief in divination. 3) There were almost twice as many respondents who directly consulted fortune-tellers were as respondents who did not consult fortunetellers. 4) The reasons for consulting fortunetellers were job problems, home problems, health problems by in that order. 5) The respondents almost always interpreted the cause of physical disease and mental disease as being psycho-sociological, but 1% of them explained mental disease as a shamanistic manitestation. 6) In case of disease, the reasons for consulting a fortuneteller was a) no hope of recovery from the sickness in any other way, b) the chronic disease in that order. 7) Of the respondents, 65% answered that diseases could not be cured by a 'Gut' (the performance done by the shaman), but 27% of respondents thought that disease could be cured by a 'Gut' in the case of mental disease. 8) Sixty six percent of the respondents answered that they have experienced praying for their wishes with clean water(井華水). 9) While 54% of the respondents answered that they have seen or heard the 'Beung Gut'(the performance to pray for recovery of sickness done by the shaman), 46% responded that they have never seen or heard it. 10) To the question 'do you intend to have a 'Beung Gut', 51.7% of respondents answer 'no' strongly, but 48% of them say 'yes' or took a compromising attitude. 11) Generally the respondents differed in perception and attitude to shamanism. In short, females more than males, old aged more than younger aged, lower educated more than higher educated, believers in Buddhism more than believers in any other religion, and blue color more than white color have more positive attitudes to shamanism. Also men living in rural communities have more positive attitude to shamanism than men living in the large cities. Consequently, Shamanism can be understood as an anxiety relieving cultural system even though Shamanism itself looks like a cultural complex.

Various policies and studies regarding use of PBSS (Public Bike Sharing System) and Programs (PBSP) have been conducted worldwide as the number systems or programs has increased. Although various phenomena and demands have been generated by the use of PBSS in everyday life, the majority of research and the policies in South Korea have been implemented focused on commuting life. The purpose of this study aimed to understand various PBSS demands using PBSS usage data in 2018 in the Yeouido districts through classifying usage patterns and analyzing features. The rental stations were classified into three types based on weekday/weekend usage rates. The usage of Yeouido's PBSS accounted for 4.3% of the total usage in Seoul Metropolitan City, while the number of PBSS rental stations accounted for 2% of all rental stations in the Seoul urban areas. Rental stations with a higher weekday utilization rates showed high utilization rates in all four seasons and were mainly distributed in work and residential areas. Other stations showed a concentrated usage pattern in spring (April-May) and autumn (September-October) seasons, and their locations were close to the entrance of nearby parks. Besides, renting and returning were often concentrated at certain rental stations for high weekend utilization as compared to the pattern of high weekday usage. Therefore, PBSS management and programs should be operated to reflect various usage demands rather than uniform PBSS operations. The result of this study is meaningful to provide basic data for effective PBSS operation by monitoring the demand for PBSS usage in spatio-temporal terms.

Objective: It is important to assess the participation and understand the characteristics of participation for setting goal of the child's treatment and strengthening participation. In this study, we verified the validity of the LIFE-H 1.0, so that domestic occupational therapists can systematically evaluate children's participation. Methods: This study was conducted for about 2 months from February to April 2016 in 47 children with disabilities and non-disabled children. We divided the children into two groups aged 0-4 years and 5-13 years old and conducted a self-report questionnaire to parents. The collected data were verified by SPSS(Statistical Package for Social Science) statistical analysis program. Results: There was no difference between the two groups in general characteristics. In comparison of two groups, a significant difference(p<.05) was found in the LIFE-H 1.0 total performance and satisfaction score and the high discriminant validity was verified. Conclusion: The ultimate goal of occupational therapy is to increase participation. Therefore, the occupational therapist must be able to assess the level of participation and than set the goal of intervention. This study confirms the high level of validity and expects that Korean version of LIFE-H 1.0 will be widely used in clinical field and research.
