Objectives: Smokers who had failed to quit smoking were frequently reported that life stress mostly interrupted their abstention. Stress vulnerability model for smoking cessation has been considered, and most of contemporary smoking cessation programs help smokers develop coping strategies for stressful situations. This study aims to investigate the appropriate coping styles for stress of abstention from smoking. The result of investigating the relationship between abstention following smoking cessation program and coping styles would suggest useful information for those who want to stop smoking and health practitioners who help them. Methods: Participants were 69 smokers (62 males, 7 females) participated in a hospitalized smoking cessation program, whose mean age was 44.89 (SD=9.61). Participants took medical test and completed questionnaires and psychological tests including: Fagerstrom Test for Nicotine Dependence and Multidimensional Coping Scale. To identify participants' abstention, researchers followed them for 2 years. To identify whether abstained or not and encourage them to abstain, researchers called them on the telephone once a week for 3 months. After 3 months, they were contacted every other week till 6 months passed since they left smoking cessation program. And they were contacted once a month for other 18months. Researchers also contacted their family to identify their abstention. Data Mining Decision Tree was performed with 37 variables (13 variables for the coping styles and 24 smoking-related variables) by Answer Tree 3.0v Results: Forty four (63.8%) out of sixty nine for 2 weeks, 34 (49.3%) for 6 months, 25 (36.2%) abstained for 1 year, and 22 (31.9%) abstained for 2 years. Participants of this study abstained average of 286.77 days from smoking. Included variables of a Decision Tree model for this study were positive interpretation, emotional expression, self-criticism, restraint and emotional social support seeking. Decision Tree model showed that those (n=9) who did not interpret positively (<=7.5) and criticized themselves (>6.5) abstained 23 days only, while those (n=9) who interpreted positively (>7.5), expressed their emotion freely (>6.5), and sought social support actively (>11.5) abstained 730 days, till last day of the investigation. Conclusion: The results of this study showed that certain coping styles such as positive interpretation, emotional expression, self-criticism, restraint and emotional social support seeking were important factors for long-term abstention from smoking. These findings reiterate the role of stress for abstention from smoking and suggest a model of coping styles for successful abstention from smoking. Despite of limitation of this study, it might help smokers who want to stop smoking and health practitioners who help them.

This study aims to analyze the content and methodological aspects of converging scientific technology and humanities in 233 elementary school STEAM programs developed and publicized from 2012 to 2015, to provide the basic materials and implications for editing and supplementing the development of future STEAM programs or policies, or on-site applications of developed programs. The analysis results show that among the Liberal Arts courses of the STEAM program, including Korean, Social Studies, and Ethics, the level of convergence was lowest in Ethics. This seems to be due to the fact that convergence between scientific technology and humanities tended to emphasize a cross-studies convergence over a content convergence done with a specific purpose. In terms of methodological convergence between scientific technology and humanities, the level of convergence of humanities at a normative level was relatively lower than that at a descriptive level. Although a quantitative comparison of the two methods was not significant, it is rather concerning that due to simply converging descriptive humanities, students may not be so aware of the double-sidedness of scientific technology, despite the discovery of some programs that need re-evaluations of their ethical or normative directions. Moreover, the results showed that the cases of converging scientific technology and humanities at a normative level that were analyzed in the STEAM program can be divided into 'complementation of humanities to utilizing scientific technology' and 'complementation of humanities to research in scientific technology and development.' Based on such research results, the study discusses the development of STEAM programs and policies and directions for editing and supplementing programs on-site.

A study was conducted to investigate the effect of supplementing earthworm meal(EWM) on the egg quality and performance of laying hens. A total of 360 laying hens at 55 weeks of age were fed the experimental diets containing 0(Control), 0.3 and 0.6% of EWM for 5 weeks. Eggs were collected and weighed in every day and egg production and feed conversion were weekly recorded. However egg quality were measured fer last week of experimental period. When fed both 0.3 and 0.6% of EWM, egg production and daily egg mass tended to increase but were not different between those treatments. Feed intake and feed conversion ratio of laying hens were not different among three groups. Egg shell thickness, breaking strength, color and egg yolk color were tend to improve in both 0.3 and 0.6% of EWM compared to those of control. The haugh units(HUs) showed no difference among each treatments at 14 after laying egg, but increased in EWM treatments compared to control for storage period. As, Cd, Cr, Hg and Pb detected 4.41, 1.23, 1.18, 0.00 and 3.39ppm in EWM, respectively, but which were not detected in control. It assumed that supplementing 0.3% of earthworm meal in the 55 weeks old laying hens diet, improved the laying performance and egg quality.

Objectives: The purpose of the study is to investigate and analyzed the current status of a dental hygiene curriculum according to the dental hygienist competency. Methods: The study subjects were 59 courses in the department of dental hygiene in G University from April 1 to May 30, 2015. Except for liberal arts, 51 courses were finally selected and analyzed for the relationship between the curriculum and competency. For each course, systematic reviews were made by subject name, core competency, achievement goals, lecture hours, weekly themes, and learning goals. Three experts in the dental hygiene evaluated and analyzed the association of competency and goals. Results: Each course was operated by the goal from one to twenty two competencies of dental hygiene. Achieving one item of competency in a course required 13 hours on the average from minimum 2 hours to maximum 30 hours. More than 20 courses were operated and more than 900 hours were necessary for achieving the competency. The competency included the contents of 'Be able to utilize basic medical and dental knowledge in dental hygiene care and patient care' among the dental hygiene competencies. Conclusions: Competency based dental hygiene education will provide theoretical background for defining the identity of dental hygienist as a health care worker and to encourage professionals who contribute to the recognition of healthy society. Further research should be continued for improving the competency-based dental hygiene curriculum and education methods for implementing the curriculum within the paradigm of health care services.

The Far Infrared Ray (FIR) is part of the natural energy as light spectrum of sunlight. Human can disentangle the colors within visible ray, but FIR is invisible to human sight because it has longer wavelength than visible ray. The effect of using FIR on broiler performance, blood biochemical profiles and fecal gas emission from litter. Day-old semi-broiler chicks (Ross ♂ ${\times}$ Hyline ♀) were obtained and assigned to eight pens, 2 replicates of white and green color LED light, and with FIR on each color light, in a 20L:4D of lighting program. The body weight gain and feed efficiency were tend to improve under the green color than white color, which were increased by exposing to FIR on both color light. Emission of ammonia and lower hydrocarbons from litter were not different from each color but there was a decrease by exposing to FIR regardless of light color. The level of blood aspartate aminotransferase (AST) tends to be decreased under green color than white color, and this tendency becomes more pronounced as exposing to FIR. Therefore significantly increased under white color without FIR than green color with FIR (P<0.05). The levels of albumin and immunoglobulin were not different from each color but there was an increase by exposing to FIR regardless of light color. In conclusion, exposing to Far Infrared Ray (FIR) when broiler raising, there is potential to increase broiler performance because of improvement of bioactivity and raising environment.

The study was conducted to investigate the effect of dietary Zizyphus jujuba seed meal on broiler performance, small intestine and cecal length, gizzard weight and fecal gas emission. A total of 180 day-old broiler chicks (Ross) were randomly divided into 4 groups, fed the commercial diet containing 0, 0.3 (T1), 0.6 (T2) and 0.9 % (T3) of Zizyphus jujuba seed meal from two to 5 weeks of age. Body weight gain and feed efficiency (feed/gain) were significantly increase in T2 than other groups at 3 weeks age (P<0.05). There was no statistical difference in body weight gain and feed efficiency (feed/gain) by feeding Zizyphus jujuba seed meal, although they tended to be improved by treatment during whole experimental period (5 weeks age). The gizzard weights of three treatment groups were higher than control. But no difference among three treatment groups was observed. The small intestine and cecal length was no change by feeding Zizyphus jujuba seed meal. Emission of $NH_3$ and VFA gas from excreta were significantly decreased from 5 to 10 days of storage period (P<0.05). In conclusion, the results of this study showed that the addition of Zizyphus jujuba seed meal at 0.3 to 0.6 % to the diet has increased digestibility of feed and the reduction of $NH_3$ emissions from feces, there was a possibility of improvement in body weight gain of broiler chickens.

This study aims to examine the effects of art therapy on challenging behavior of schoolchildren. For this purpose, I selected one class of 4th year student of S primary school, located at Jeongeup city, Jeonlabukdo, and selected 4 study subjects through examination of K-CBCL children. juvenile behavior evaluation scale, characters, school life and K - HTP test. With regard to procedure of this study, I carried out art therapy program at the art class for 60 minutes one time a week for 4 months, a total of 17 sessions from Apr. 3, 2007 to July 24, 2007. I made this program with some modification in reference to Arts Therapy Technique (Counpia Remote Training Center, 2005), Group Art Therapy (Choi Seon Nam. Kim Gap Sook. Jeon Jong Kuk, 2007) and the Effects of Peer Group Art Activity on Sociality Skill of Offensive Children (Park Ju Yeon. Lee Byeon In, 2005). For each child, I compared and analyzed the changes in score of K-CBCL children. juvenile behavior evaluation scale, behavior by K-HTP (dynamic house-wood-human figure test) analysis and by school life(KSD) image analysis before and after treatment. I also carried out qualitative analysis on behavioral feature of each child for each session. This study obtained the following conclusions. First, child A showed positive change in comparison before and after art treatment program of score K-CBCL children. juvenile behavior evaluation, K-HTP image test and school life. Since he was so active and wanted to obtain good evaluation from anyone that he frequently had quarrel with friends, spoke against others well and beaten others much but was changed and did not speak against others or beat. Second, child B showed clear difference in comparison before and after art treatment program of score K-CBCL children. juvenile behavior evaluation, but no significant difference in K-HTP image test and school life. However, I observed substantial changes. While he could not speak frankly to others, felt empty in mind and was offensive in personal relations, he was changed, did not have quarrel with others or speak against others that much and improved his relationship with friends or teachers. Third, child C showed positive change in score of K-CBCL children juvenile behavior evaluation after art therapy program. In comparison of K-HTP image test and school life treatment before and after treatment, he still longed for mothers in mind but found rather stable after treatment. Fourth, child D showed positive chance in score of K-CBCL children. juvenile behavior evaluation scale after art therapy program, but almost no changes in K-HTP image test. But he depicted good relationship and socializing with other friends in school life. While he could not carry his point due to social immaturity and felt depressed, he got more confident. This result of study showed that art therapy had positive effects on correction of schoolchildren.

The purpose of this study was to investigate effects of 12-weeks aerobic exercise and taekwondo exercise on brain wave activation and brain-derived neurotrophic factors in undergraduate male students. Twenty four male subjects participated in this study. They were separated into a Control group(CG; n=8), Aerobic training group (ATG; n=8) and Taekwondo training group(TTG; n=8). ATG and TTG participated in Aerobic exercise training and Taekwondo exercise training for 12 weeks, 50~80 minutes per day, 3 times a week at 60~80% HRR respectively. All data were analyzed by repeated measures two-way ANOVA. As a result, there were no significant differences in the body composition and brain activation in all groups. However BDNF increased significantly after 12 weeks in the aerobic training groups(ATG). It is suggest that 12 weeks of regular Taekwondo exercise training did not statistically affect brain activation and neurotrophic factors in undergraduate students.

This study redesigned the Korean speaking classes to foreign undergraduate students as flipped learning classes and verified their effect on speaking-related emotional variables. In addition, international students' perceptions of what experiences are needed to improve speaking efficacy in Korean were examined. For this purpose, the 'Creative speaking' subject for freshmen was redesigned to flipped learning class and operated for one semester. To analyze the effect of speech-related emotions, a paired t-test was conducted on 26 foreign students' pre-post scores of speech efficacy and anxiety. Also awareness of experiences needed to improve speech efficacy was surveyed and content analysis was conducted. As the result, the speaking efficacy of students after flipped-learning has been significantly improved. This means that flipped learning classes for the Korean speaking are effective for the positive emotions of foreign students speaking Korean. In addition, international students perceived that Korean speaking efficacy can be improved by practicing speaking in Korean, learning with Korean colleagues. Based on these results, several discussions and suggestions were presented.

Human resources specialized in product development (PD) being essential in industry to enhance their competitiveness in the market with differentiated products, the PD curricula of domestic universities are in need of restructuring to better provide a comprehensive and diverse spectrum of knowledge as well as practical experiences for PD. We compared the PD curricula of selected domestic and foreign universities and identified advanced features of PD curricula. The major portion of the information used in our benchmarking of the seven, three domestic and four foreign, universities is obtained through their official websites. At domestic universities, the PD curricula comes in different sizes and is administered at the departmental level. On the other hand, each foreign university has her own unique form of PD curricula which is formulated on the firm basis of multidisciplinary collaboration among schools of Engineering, Management, and Arts with diversified program options ranging from giving course credits to offering various certificates and degrees. The industrial sponsorship in the form of financial support and mentorship at foreign universities is much more noticeable than at domestic universities. The survey results of the present study can be effectively utilized to develop an effective PD curriculum.
