The purpose of this study is to develop geological field sites for open ended education and inquiry learning, and to find the influence of field study on the affective domain in science and the achievement. As for the field sites, we used the areas ranging from Chaeseokgang- of Kyeokpo, in Buan, to around Bangsanje from Naejang-dong in Jeongeup to Ssangchi-myun in Sunchang-kun, Jeolla North Province. The affective domain in science is composed of three parts-cognition of science, interests toward science, and the scientific attitudes. to evaluate the stage of the achievement, we used questionnaire composed by 25 items. While the control group does not show any change in three parts of the affective domain, the experimental group shows positive changes, from 2.44 to 2.37 (cognition of science), from 3.15 to 3.08 (interests toward science), and from 2.91 to 2.74 (scientific attitudes) on Likert Scale. Also the score arranged by the analysis of covariate shows that the experimental group is more positive than the control group by 0.12 point in cognition of science, by 0.15 point in interests toward science, and by 0.23 point in scientific attitudes. In terms of the stage of achievement, the score of the experimental group, which is arranged by analysis of covariate, is 7.68 higher than that of the control group, on maximum of 100.

Objectives: The purpose of this research is to provide foundational data for reeducation concerning prehospital emergency care in order to improve the performance of emergency medical technicians (EMTs) working at 119 fire safety centers. Methods: Data were collected using a mail-in questionnaire developed by researchers from 288 subjects, who were EMTs working at 119 fire safety centers and local units in the Gwangju Metropolitan City and South Jeolla Province, from March 1, 2009 to April 31, 2009. Results: The mean score for EMTs' knowledge on drug intoxication was7.04 out of a total of 10 points. The mean score for EMT's attitude of emergency treatment performance on drug intoxication was 2.96 out of a total of 4 points. The level of EMT's knowledge is relatively high regarding prehospital care for drug intoxication. The EMT's attitude of performances demonstrated an understanding of the patients' conditions. However EMTs did not actively explain the prognosis and medical conditions for their patients. Conclusions: This research will contribute to making plans for reeducating emergency crew working at 119 fire centers so that can they have a more active attitude towards prehospital emergency medical care.

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 author has investigated epidemiological features of human cases of epidemic encephalitis (E. E.) in the Republic of Korea and the status of antibody requisition in pre-and post-epidemic time. And virological and serological studies with regarding the relationship of E. E. infection between human and piglet, and field survey against its vector by means of virus isolation from mosquitoes were carried out. Finally, vaccine field trial against human population has also been evaluated in order to confirm its effectiveness. The results of the studies are summarized as follows : 1. The annual incidence of reported cases during the past 25 years (1949-1973) in the Republic of Korea has shown two patterns, one was typical cyclic incidence and the other one was irregular. Annual average morbidity and mortality rate per 100,000 population were 5.7 and 2.1 and fatality rate was 34.6% in typical cyclic years. 2. With regard to the geographical distribution of E. E., the province of Jeolla-Bug-Do illustrated the highest incidence regardless of the epidemic size. 3. The main epidemic period was between mid-August and mid-September (above 90% of the total number of cases). The first case was reported in middle of July and the epidemic ceased in late of October. 4. An analysis of the age distribution of cases of E. E., has shown that above 90% of the total cases occurred in the age groups under 14 years and it was noted that about its 54% were occurred in the age groups between 5-9 years group. 5. Through the Haemagglutination Inhibition (H-I) test for the laboratory diagnosis of E. E., it was found that higher H-I antibody titer was usually detected in the convalescent phase, 15 days after onset. 6. The H-I antibody survey against 563 healthy population by age groups during the pre-epidemic season showed that 422(75%) were less than H-I titer, 1:20 and 122(21.7%) were positive H-I titer, 1:20. Among the 94 American in Seoul who had not been in E. E. endemic area previously only one person had appeared sero-conversion as a H-I titer of 1:80 after post-epidemic season. 7. The E. E. virus could be isolated from the mosquitos pools-C, tritaeniorhyncus which were caught between late July and middle August. 8. E.E. Virus was also isolated from piglet blood on early August and H-I antibody conversion was occurred mostly on middle of August. 9. H-I antibody sero-conversion rate reached to high level when vaccine purified by mouse brain tissue inoculated, showing 98.9%. Higher antibody titer was acquired when booster inoculation was performed, Four fold rise of H-I add N-T antibodies was confirmed with 93.2% and 82.1% respectively.

The purpose of this study was to develop an inclusive dental hygiene practice model in an effort to stir up the self-directed learning of learners to boost their problem-solving skills and ability of providing inclusive personal oral health care in a systematic and efficient manner. The subjects in this study were 41 dental hygiene students who were in their second year in C college located in South Jeolla Province as of 2009. An inclusive dental hygiene practice was implemented during a 15-week period of time from August 31 to December 7, 2009, and a self-administered survey was conducted before and after that by using the same questionnaires. Whether there were any differences between before and after the application of the inclusive dental hygiene practice model was checked, and there was improvement in all the learning motivation, self-directed learning capabilities and satisfaction level. Concerning the relationship of academic standing to changes in learning motivation, self-directed learning capabilities and satisfaction level, the inclusive dental hygiene practice model brought more favorable changes to the students in the lower tiers. The inclusive dental hygiene model should be applied to not only practical courses but theoretical ones so that learners could make progress both in theory and practice, and evaluation tools geared toward assessing their academic achievement and practical abilities should be developed.

The purpose of this study was to examine the symptom of dry mouth of workers, their subjective oral symptoms and factors affecting their oral health-related quality of life (Oral Health Impact Profile, OHIP-14) in an effort to provide information on the development of oral health promotion programs geared toward workers. The subjects in this study were the workers in five different companies in North Jeolla Province. After a survey was conducted from August 1 to September 20, 2012, the collected data were analyzed. The findings of the study were as follows: The office workers got 2.59 in oral dryness, and the sales associates got 1.82. The oral dryness of the former was severer than that of the latter (p<0.001). The irregular workers got 2.05 in OHIP-14, and the regular workers got 1.82 (p<0.001). Symptom of dry mouth had a positive correlation to OHIP-14 (r=0.456). OHIP-14 was positively correlated with age (r=0.209) and negatively with academic credential (r=-0.136). OHIP-14 was more significantly affected when their symptom of dry mouth was severer (${\beta}=0.383$, p<0.001), when they were older (${\beta}=0.221$, p<0.001) and when they felt they had oral diseases (${\beta}=0.146$, p<0.01). In conclusion, quality programs should be developed to promote the oral health of industrial workers in consideration of the influential factors for the oral health-related quality of life of the workers, and the government should pay more attention to related policy setting to improve the oral health of industrial workers.

Objectives : This study was to examine the recognition and understanding of the use, application of oral hygiene supplies among dental clinic patients in a bid to stress the necessity of education on the right awareness and use of oral hygiene supplies, to provide information on the development of educational programs and ultimately to help promote the oral health of people in general. Methods : The subjects in this study were 314 patients who visited dental clinics in North Jeolla Province in June 2009. Results : 1. Out of oral hygiene supplies, the largest number of the patients investigated(74.6%) were best cognizant of dental floss, and the greatest group(77.7%) had the right understanding of the use of toothpick. Currently, the oral hygiene supplies that were most widely in use were toothpicks(43.2%). 2. As to the relationship of awareness and understanding of the use, application of oral hygiene supplies to subjective oral health status, 50.0 percent of the patients who understood the use of toothpick found themselves to be in good health, and the gaps between them and the others were statistically significant. Among those who were aware of dental floss, the largest group(51.4%) considered themselves to be in good shape, and in the event of those who understood the use of dental floss, the greatest group(49.2%) deemed themselves to be in good health. Out of those who understood the use of mouse rinse, the largest group(53.7%) thought they were in good health(p<0.05). 3. Recognition of interdental brush, understanding of its use and whether to use it currently or not were identified as parents to use oral hygiene supplies recommended by dental clinics(p<0.05). 4. Recognition of interdental brush, understanding of its use and whether to use it currently or not were identified as patients to use oral hygiene supplies recommended by dental clinics(p<0.05). 5. The largest group of those who didn't put dental floss to use didn't use it for other reasons unspecified in the questionnaire, and the second greatest group of them didn't use it since it was so onerous to do that. There were statistically significant differences in the reason why they didn't use the oral hygiene supplies(p<0.05). 6. Awareness of dental floss and interdental brush, understanding of the use of the two and whether to use the two at present or not made statistically significant differences to whether they were likely to use the oral hygiene supplies in the future. And whether they were likely to use the oral hygiene supplies in the future was statistically significantly different according to awareness of mouse rinse and understanding of the use of it as well(p<0.05). Conclusions : Dental hygienists have to provide patients with various data of oral hygiene devices through oral health education and then only patients caring in dental clinics can choose the appropriate devices to claim for their own disease.

The purpose of this study is to build up the expert system with more subdivided qualifications and improved qualities with the development of the security industry. And also it is to analyze a survey measuring how satisfied they are with curriculum, teaching faculty, educational administration, facilities among 439 private guards completing a course in Korea private guard educational institution and registered in the National Police Agency in Seoul, Gyeonggi, Chungcheong, Gyeongsang, Jeolla province. For this, SPSS(Statistical Packages for Social Science) 15.0 Version was adapted to analyze and other analysis methods used for this study are like these: frequency, reliability analysis, regressive analysis, moderated multiple regression, post hoc test for categorizing the performance changes, looking into the characteristics, examining closely job performance, intention to quit one's job, and inquiring into the influence how satisfaction measurement at education training satisfaction makes on carrying out one's job. Firstly, The Effect Satisfaction at The Program has on Performing One's Duty With respect to job performance, curriculum, educational administration, teaching abilities have positive influences on it. On the other hand, with respect to quitting one's job, curriculum just makes positive effects on leaving one's work statistically. It indicates that systematic and effective curriculum, administration, teaching faculty or contents with high quality rather than just education facilities would make the task performance excellent and satisfaction at the program well in regards to making effects on the task performance. Secondly, The Effect Satisfaction at The Program has on Performing One's Duty with Social Supports Despite being the fact that statistically any strong correlation between curriculum and social supports, one between education facilities and social supports, one between teaching abilities and social supports, and one between educational administration and social supports do not have influences on carrying out job performance, it turns out that satisfaction at the program and social supports make positive effects on performing one's task. In conclusion, the entire social system and support need to be improved and some institutions appropriate for satisfaction at the program should be established as soon as possible.

As concrete structures are getting larger, higher, longer, and specialized, it is more required to develop steel fiber concrete and apply to the real world. In this research, it is aimed to have fatigue strength examined, varying the steel fiber content by 0%, 0.75%, 1.00%, 1.25%, by experimental study of Two-spans Beam with Steel Fibrous with repeated loads. The ultimate load and the initial load of flexural cracking were measured by static test. In addition, the load versus strain relation, load versus strain relation, load versus deflection relation, crack pattern and fracture mode by increasing weight was observed. On the other hand, the crack propagation and the modes of fracture according to cycle number and the relation of cycle loading to deflection relation and strain relation was observed by fatigue test. As the result of fatigue test, Two-spans Beam without Steel Fibrous was failed at 60~70% of the static ultimate strength and it could be concluded that fatigue strength to two million cycle was around 67.2% by S-N curve. On the other hand, that with Steel Fibrous was failed at 65~85% of the static ultimate strength and it could be concluded fatigue strength to two million cycle around 71.7%.
