The purpose of this study was to examine the smoking-related characteristics of health and non-health related majors and the relationship between the smoking dependence and oral health practice of college students. The subjects in this study were the college students who were selected by convenience sampling from four different universities in the city of Jeonju, North Jeolla Province. The answer sheets from 811 respondents were analyzed. The findings of the study were as follows: The rate of the smoker students whose major was related to health stood at 20.6 percent, and that of the smoker students whose major was not related to health stood at 29.4%. There were significant differences according to the track of their major (p<0.05). As for links between smoking dependence and a plan to quit smoking, 32.7% of the health-related majors who considered themselves to depend on smoking replied they would give up smoking if there would be a rise in cigarette price (p<0.005), and 37% of the nonhealth related majors who considered themselves to depend on smoking gave the same answer. Thus, the largest group of the students intended to quit smoking if there would be a rise in cigarette price, and there were statistically significant differences according to smoking dependence (p<0.05). Concerning connections between smoking dependence and actual oral health practice, the non-health related majors who didn't consider themselves to depend on smoking got 3.53 in the item whether they brushed their teeth twice or more a day (p<0.05). In conclusion, the development and implementation of systematic programs that are to teach students to stay away from or quit smoking and take care of their oral health regardless of their major are required to step up the oral health promotion of college students.

The purpose of this study is to activate Home Economics integrated career education for strengthening career development competency in a career education intensive semester & grade system. To do this, the trend of subjects-integrated career education, and the relationship between achievement standards of Home Economics in high school and career development competency were analyzed, methods for Home Economics subjects-integrated career education were investigated, then a case study was developed. The main research results of this study are as follows. First despite the importance of subjects-integrated career education, there are much rooms to improve in operation of the career education intensive semester & grade system. Therefore, the systematic preparation for subjects-integrated career education is required at the time of application of the 2015 revised curriculum and the expansion of the career education intensive semester & grade system. Second, all achievement criteria in three domains of Home Economics were shown to be highly related to career development competency. Eventually it could be confirmed that the Home Economics is a core subject that meets the goals of career education and hones career development competency to be prepared as future human resources. Finally, in order to strengthen the career development competency, a case study of Home Economics integrated career curriculum focusing on the association with curriculum-teaching & learning-evaluation was developed and proposed. Even though the developed case study of curriculum has not been proven yet in the class, this study is expected to contribute to the enlargement of career education of Home Economics in the career education intensive semester & grade system as fundamental data for integration of Home Economics and career education.

In this paper, the proposing a fundamental data for a systematic and effective organizational management by examining the extent of the levels of conflict perceiving among individuals of social welfare workers in the Busan community social welfare center, a social welfare organizations, and investigating the related influencing factors are the purpose of the study, The summary of this study is as follows. At first, it is dysfunctional when the level of conflict is either exceedingly high or low in the interrelational conflict aspect. However, the social welfare workers' working in the community social welfare center, the extent of individual conflict is relatively low as 2.37 out of 5 points. Secondly, the multi-regression analysis is operated for controlling the population sociological factors and measuring the effectiveness of the conflict factors to the level of conflict. The influencing factors affects the result in the order of greater extent are communication factor, leader's flexibility of leadership factor, spontaneity among personality, confidentiality. As a result, Not like the case that in the technological bureaucratic organizations such as the enterprises or industrial organizations, in the human service organizations including social welfare organizations, these technological bureaucratic paradigm does not applying directly since the material of organization is composed of humans who are given moral values. Therefore, this paradigm should be put as a presupposition of the conflict management strategy. And, the communication among colleagues, learning a reasonable problem solution method, or the chances of education or training for establishing a sound human relationship should be prepared in order to lower the level of the conflict among individuals in the community social welfare department. Furthermore, professional education programs are needed for not only supporting an effective supervision and consultation(consultation with superiors and colleagues), but also, working with confidentiality and pride as a professional.

In this study, the characteristics and oral health status of manufacturing workers were investigated to confirm the factors affecting their risk of developing dental caries and to prepare basic data for developing oral health promotion programs for such workers. A self-administered questionnaire survey and saliva microorganism examinations (S. mutans and Lactobacillus tests) were conducted from July 1 to August 1, 2014 targeting the manufacturing workers in the Busan and Gyungnam areas, to confirm the factors affecting dental caries development among manufacturing workers. As a result, the risk of dental caries was found to be higher in the workers who worked for 10 hours or longer a day than in those who worked for less than 10 hours a day, and in the smokers than in the non-smokers. A 1-point increase in the brushing pattern score resulted in 0.044 times less risk of dental caries development in the S. mutans test and 0.004 times less risk in the Lactobacillus test Therefore, systematic support is needed to improve the work environment of manufacturing workers, along with continuous oral health education in workplaces.

This study was done to explore clinical competence and factors related to competence in dental hygiene students. This study performed a survey on such an issue from March 2 to June 12, 2015 for 329 dental hygiene students who were residing in Busan and Ulsan. In the result by the satisfaction of the major, there is the highest score in the satisfaction of the critical thinking, self-leadership, satisfaction in clinical practice and ability of clinical performance. The critical thinking reveals the positive relationship with the self-leader ship(r=0.884) and the ability of clinical performance(r=0.845). Whereas the self-leader ship show the negative relation with stress in clinical practice(r=-0.796). The most important factor affecting on the clinical competence among dental hygiene students was critical thinking(p<0.001), followed by self-leadership(p<0.01) and satisfaction of clinical practice(p<0.01). In results, the critical thinking, the self-leader ship and the satisfaction of clinical practice have an effects on the ability of clinical performance of the dental hygiene students. The teaching learning strategy and the educational programs to enhance the critical thinking and self-leader ship should be developed. Furthermore, the present study can be used as the base data for the systematic and convergence program to improve the satisfaction of clinical practice and the ability of clinical performance.

The purpose of this study was the evaluation of spectral transmission of the commercial three shade guides and the relationship of hue, value, and chroma according to the transmission rate. The spectral transmittance of three shade guides - Vita Lumin Shade Guide, Vintage and Unibond Shade Guide, and Vitapan 3D-Master Shade Guide - were measured. For direct transmission measurements, each shade tabs were placed at the entrance port of the 1mm diameter intergrating sphere. The intensity of the light source passing through the shade tabs to the right angle was continuously recorded for wavelength from 400 to 700 nm. A transmission spectrum and digital data were obtained for each measurement and they were evaluated using Microcal Origin program. The obtained results of this study were as follows : 1. In Vita Lumin Shade Guide, sum of the transmission rate of the shade tabs at the wavelength 400-700nm was decreased in agreement with the arrangement order at each A, B, C, D group, except D4 shade tab. However, there were no relationships between the transmission rate of the shade tabs and the value-oriented. 2. In Vintage and Unibond Shade Guide, sum of the total transmission rate of the shade tabs was decreased in agreement with the arrangement order at each A, B, C, B group. When all shade tabs arranged in value-oriented, transmission rate was accord with the order, except D4 shade tab. 3. When shade tabs of the Vitapan 3D-Master Shade Guide have the same value and hue, sum of their total transmission rate decreased in accordance with the chroma-oriented. When the shade tabs have the same value and chroma, there were no differences from the order of the transmission rate to the various hue type. However, in the 'R' tabs of reddish hue type, the transmission rate increased at the long wavelength range area. In conclusion, we need the quantitative analyzing instruments in transmission determination. Vitapan 3D-Master Shade Guide covers the tooth color space taking into account the parameters of the systematic value, chroma, hue oriented, and the transmission rate relatively accorded with that sequence.

It is not possible to provide resonable evidence for embankment (or dam) overtopping in geotechnical engineering, and conventional analysis by hydrologic design has not provided the evidence for the overflow. However, hydrologic design analysis using Copula function demonstrates the possibility that dam overflow occurs when estimating rainfall probability with rainfall data for 40 years based on fluctuating water level of a dam. Hydrologic dam risk analysis depends on complex hydrologic analyses in that probabilistic relationship needs to be established to quantify various uncertainties associated with modeling process and inputs. The systematic approaches to uncertainty analysis for hydrologic risk analysis have not been addressed yet. In this paper, the initial level of a dam for stability of a dam is generally determined by normal pool level or limiting the level of the flood, but overflow of probability and instability of a dam depend on the sensitivity analysis of the initial level of a dam. In order to estimate the initial level, Copula function and HEC-5 rainfall-runoff model are used to estimate posterior distributions of the model parameters. For geotechnical engineering, slope stability analysis was performed to investigate the difference between rapid drawdown and overtopping of a dam. As a result, the slope instability in overtopping of a dam was more dangerous than that of rapid drawdown condition.

In Korean education, the health contents are scattered in various course subjects throughtout the primary and junior high school curriculum. So it is very difficult to provide systematic health education. The purpose of this study was to provide a guide for health education using health topic areas and major concepts that represent the scope of material that should be covered in health instruction. The steps used in selecting these health topic areas and major concepts were as follows: 1. A review of the literature related to health and health education was done to develop the rationale underlying this study. 2. Health topic areas basic to the growth and development characteristics of children, to human needs and to societal needs for healthful living were indentified. 3. The major concepts for each health topic area based on health sciences and children's growth and development levels were selected. 4. The major concepts selected were organized in sequence to guide health education from grade one to grade nine. The results of this study were as follows: 1. The identification of eleven health topic areas essential for health education. These include: personal habits and health healthy growth and development nutrition and health prevention of disease and disorders drugs and health mental health family life and health sex education accident prevention consumer health community health 2. The identification of the major concepts(generalizations) for each health topic area: 33 major concepts were identified as a guide in determining the health content of health education programs. These are 1) body cleaniness, 2) health of the sensory organs, 3) dental health, 4) exercise and rest, 5) growth and development, 6) body structure and function, 7) developmental tasks, 8) balanced nutrition, 9) eating habits, 10) food preparation and food storage, 11) sources of disease and disorders, 12) disease preventive behavior, 13) care during illness, 14) drug use and misuse, 15) drug addiction, 16) emotional responses, 17) human relationship, 18) self concept, 19) social adjustment, 20) health habits of the family, 21) interdependence of family members, 22) origin of life, 23) characteristics of man and woman, 24) sexual instinct, 25) safety behavior, 26) emergency measures, 27) criteria for selection of health products, 28) proper use of health information, 29) utilization of health and medical services, 30) environmental conservation, 31) environmental pollution, 32) population control, 33) function of public health services. 3.

Today, most construction projects have been higher, bigger, and more complicated gradually. So the domestic construction companies have been trying to understand overall construction process and relationships between activities, and adopted various management techniques and tools in order to perform a systematic and effective scheduling. However numerous problems have been occurred on the practical applications because most existing scheduling softwares adapt ADM and PDM techniques. One of them, PDM, is so uneffective because it represents the overlapping relationships between two consecutive activities only by the combinations of start and finish points between two activities. In order to supplement the demerit of PDM, Beeline Diagramming Method(BDM) is proposed as a new networking technique, it can represent two-way multiple overlapping relationships between two activities directly. However there are occurring a loop phenomenon on applying two-way multiple overlapping relationships. This research proposes and verifies the schedule computation method of two-way multiple overlapping relationships on the BDM network.

The purpose of this study was to investigate the characteristics of parents support (PS), friends support (FS), and professor support (PS) of university students, and to examine the correlation between gender, social support, and university life satisfaction (ULS). The survey was conducted using 564 college students in Gangwon-do using a questionnaire consisting of 27 social support and 5 ULS. As a result, PS, FS, and PS showed positive answers, but the PS showed relatively negative answers and ULS was not high. And regardless of gender, there was a statistically significant correlation between PS, FS, PS and ULS (p<0.00). In the correlation of gender, PS, FS, PS, and ULS, there was a statistically significant correlation between PS, FS, PS and ULS without gender (p <0.00). In order to improve the ULS, it is necessary to promote interaction through systematic friends and professors as well as parents.
