Background: By regulating the factors that contribute to oral diseases in a healthy way, oral health can be maintained and prevented. Methods: The general characteristics, PHP index, oral health behavior, and clinical periodontal index of each group were calculated by frequency analysis, and a cross-analysis (χ² test) was conducted to assess the homogeneity of the general characteristics, oral health behavior, and clinical periodontal index of the study subjects. An Oral bacteriological examination was performed by gargling with saliva. Results: The expert periodontal prevention group showed a decrease in the copy number of periodontal disease causative bacteria, and A. actinomycetemcomitans, P. gingivalis, T. forsythus, andT. denticolashowed a significant difference before and after treatment (p=0.021). In the periodontal treatment group, A. actinomycetemcomitans, P. gingivalis, T. forsythus, andT. denticolaall showed a decrease in copy number, but there was no significant difference. Conclusions: This study showed professional periodontal prevention management had some effect on periodontal bacterial reduction.

Purpose: The present study was conducted to develop the Life Respect Enhancement Program and test its effectiveness on suicide knowledge, suicide intervention skills, self-efficacy in suicide prevention, and gatekeeper behaviors among nursing officers. Methods: The program was developed according to the ADDIE model and finalized after practical need analysis, expert verification, and a preliminary study. The present study used a concurrent embedded mixed-method research design. To compare the effects of the Program and the control group on the outcome variables, a quantitative study was conducted using a nonequivalent control group with a pretest-posttest design. Quantitative data were analyzed using χ²-tests, t-tests, and RM-ANOVA. A qualitative study was conducted using FGI with six members of the experimental group 3 months after intervention completion. Results: In total, 56 nursing officers participated in the 3-month follow-up test. Compared to the control group, the experimental group showed significant improvements in suicide knowledge, suicide intervention skills, and self-efficacy in suicide prevention scores at post-test. The significant group differences in suicide knowledge and suicide intervention skills were maintained at 3 months. The gatekeeper behavior scores of the experimental group were also significantly higher than those of the control group at 3 months. Qualitative analysis of the participants' experiences with the Program yielded two themes and seven sub-themes. Conclusion: The newly developed Life Respect Enhancement Program demonstrates significant effects on suicide knowledge, suicide intervention skills, and gatekeeper behaviors. Thus, this program is recommended to promote suicide prevention competencies among nursing officers in military clinical settings.

Since 1971, the aptitude test for domestic train drivers has been long maintained. With the revision of the Railroad Safety Act in 2006, the aptitude test was changed from the type of written and skill test into the type of question-and-answer and reaction test. However, the main structure of the test was not changed. In this paper, we focus our attention on the improvement of the present aptitude test. We surveyed on two groups, one is the railroad expert group and another is train driver's group, questioning about the importance of the domestic and foreign aptitude test items. Based on the analysis, we suggest desirable aptitude test system for the railroad safety.

The purpose of this study is to propose a decision-making technique for selecting waterproofing methods using the Analytic Hierarchy Process (AHP) technique. In this study, a questionnaire survey was given to a group of specialists, which included design specialists, construction specialists, and maintenance specialists, regarding their experience with roof waterproofing methods. The 1st level hierarchy of the questionnaire survey addressed the function, economics, and maintenance of each of the roof waterproofing methods. The rank of 13 items of questionnaire, which is the 2nd level hierarchy of the questionnaire survey, is calculated using Expert Choice Solution. The analysis of questionnaire survey shows that each specialist selects different roof waterproofing methods, and all specialists make much of waterproof performance.

This study was intended to investigate the influences of consumer's self-monitoring, pioneer brand awareness, types of endorsers on quality perception of "me-too" brands with a focus on outdoor brands. The design of this research was comprised of 2 types of self-monitoring(high vs. low), 2 types of pioneer brand awareness(high vs. low), 2 types of endorsers(professional expert vs. typical consumer). The study was carried out by using samples from residents of Seoul and Gyeonggi area. The number of subjects used in the final analysis totaled 243, with age of the consumers ranging grom 20's to 50's. The results of this study were as follows. Self-monitoring, pioneer brand awareness and types of endorsers had shown a statistically significant correlation effect on the quality perception of me-too brands. Especially, in the high-level self-monitoring group, the effect of pioneer brand awareness on quality perception of me-too brand was significant when typical consumer model was given. The result presents that using a professional expert model in the market rather than a typical consumer model can offset the quality perception of pioneer brand with low awareness.

The purpose of this study were to investigate the job analysis questionnaire was mailed to 250 dietitians who are members of The Korean dietetic association practice group in self-operated foodservices(hereafter group A)and 250 dietitians who are employed in contracted foodservice companies(hereafter group B). Completed questionnaires were received from 285 dietitians(121 in self-operated, 164 in contracted) ; a response rate of 57%. Statistical data analysis was completed using the SAS/win packages for descriptive analysis, t-test, $x^2$-test, The results of this study can be summarized as follows. 1. The dietetic training or internship experiences were significantly different between the two sample group(p<.001), but the perceptions of needs for training or internship were not different between and they thought one to six month training would be needed for the job. 2. The question about the time needed in order to perform an expert job was answered significantly differently(p<.001) 3. Group A usually took part in obligatory continuing education and short-term training courses, and group B usually took part in obligatory continuing education and on-the-job trainings, respectively. However both group perceived all three types of educations would be needed for performing the job better. 4. As for the physical demands of the job, a certain degree of accuracy and dexterity for physical tasks and equipment operations was needed for the job. Concerning the mental demands, they answered that their job needs considerable creativity and judgement for planning and performing their tasks was needed. 5. As for responsibilities, group B's responsibilities were heavier than group A’s(p<.001) and need for confidentiality was also greater for group B than for group A(p<.001). 6. As for the supervising role differences, group A rarely received supervision from others and they were given directions only in essential situations, whereas group B was usually supervised when planning and performing their job and tasks, showing significant difference in positions between the two sample groups(p<.001). But each group supervised co-workers and employees in their department. 7.
