Even though, the Korean private Security Guard's industry is developing, it did not reached at the expected quality services because of the below cost tendering from flooded small security companies, consequently low pays and fragile benefits occur therefore, the skill level and morale decreased. Also, the private security guards field's education, training and development of expert certification system is not enough. One of the plans to solve these problems can be invigorate the certification system. The improving ways are suggested after the research and the analysis of the certification system as below. First, the qualification system to become a security leader will need to add directly related subject, skill examination and continuous refresh training. Moreover, it needs accurate needed the number of the securities and the reduction of the 1st examination exemption object. Second, the qualified system to be become securities will need to strengthen on standard of qualification and focus on skill evaluation, the job education need to state by the law, also exemption for applicant who approached requirements.

Purpose: Increasing use of computer aided design-computer aided manufacturing (CAD-CAM) system and number of design software made design of restoration easy and quick. Outcome of restoration has been dependent on dental technician's wax up proficiency, dentists can design restoration for themselves now. This study aims to investigate the outcome of restoration designs, according to handling skill of CAD-CAM design tool. Materials and methods: A patient's mandibular right 1st molar was prepared. After taking impression, stone model was made, scanned the stone model with 3 shape intra-oral scanner, stereolithography (STL) file was extracted. With 3shape dental designer, one dental technician with more than 5 years work experience (designer 0) and three dental technicians with less than 2years work experience (designer 1, 2, 3-group DT) and 4 1st year residents (designer 4, 5, 6, 7-group RT) designed gold crown on the same STL file. Designed crown's MD (mesio-distal) and BL (bucco-lingual) diameter, height of crown, inter-cuspal distance, number of occlusal contact points were compared. Statistical analysis was carried out, test of normality within each group, using independent t-test. Number of contact points were compared, using Wilcoxon signed-rank test. Results: There was no significant difference between group DT and group RT. Number of contact points also resulted in no significant difference. Conclusion: The outcome of each designed crowns showed no statistical differences, in values which can be expressed as numbers. Subjective factors were different. With increasing proficiency in handling designing software, fabrication of restorations according to each designer's occlusal concept can be made easy.

A firefighting simulation was developed in order to assess the physical work capacity of firefighters. The simulation consisted of eight common firefighting tasks, including walking with radiant heat for 3 min while wearing full personal protective equipment (PPE). Nine professional firefighters performed the test a total of three times with a 5 min rest interval between each session. The entire series of tests took approximately 30 min to complete ($381{\pm}30s$). Rectal temperatures were found to increase from $37.4{\pm}0.3^{\circ}C$ to $38.5{\pm}0.4^{\circ}C$, while heart rates were found to increase from $92{\pm}18bpm$ to $185{\pm}13bpm$ during testing. Time to completion of the test drills and non-modified physical fitness values showed a significantly negative correlation (r = -0.728, p < 0.05). Firefighters who had longer periods of firefighting service had longer duration time and also recorded higher scores using an integrated scoring system of time to completion (TTC) and physiological strain index (PhSI). The results indicated that the determination of TTC alone can be a misrepresentation of capability, as it neglects to account for accumulated heat strain. The simulated firefighting test provided a useful insight into physical fitness level, but also the comprehensive work capacity of the firefighters when assessed based on TTC and PhSI.

The purpose of this study is to examine the influence of the distributed leadership upon kindergarten teachers' commitment of teachers. As a result of the analysis, first, the teachers' recognition on the distributed leadership at a kindergarten was confirmed to have a significant difference depending on the teaching career and the academic background. And the commitment of teachers perceived by the kindergarten teachers was identified to have a statistically significant difference according to the teaching career, academic background, and scale. Second, the kindergarten situation and the teacher leadership among sub-factors of the distributed leadership were indicated to have a positive effect on the commitment of teachers. Especially, the teacher leadership was confirmed to have a positive impact on the whole of professional consciousness, educational love, and passion, which are sub-factors in the commitment of teachers. What the distributed leadership has a positive influence upon the commitment of teachers at a kindergarten can be known to be ultimately the time when a teacher oneself fully recognizes responsibility, influence, and authority with thinking that a teacher oneself is a leader, rather than a director's leadership. Accordingly, a director's many responsibilities and authorities need to be properly entrusted so that the kindergarten teachers can display much more leadership.

A Calculator-Based Laboratory (CBL) system was introduced to science teachers and their perceptions to its classroom application was assessed. A CBL survey instrument was responded by 54 middle and high school science teachers who undertook a three-hour workshop of science experiments with CBL system. There were significant differences in teachers perceptions to CBL system among gender, school level, school location, teacher's degree, and years of teaching in terms of learning CBL system, applicability of CBL system for science classrooms, and effects on science achievement. Male teachers showed significantly (p<.05) higher agreement to learning of CBL system and applicability for science classrooms than female teachers. Compared to middle school teachers, high school teachers showed significantly (p<.05) high interests in CBL applicability for science classrooms and perceptions that there will be an increase of science achievement. Teachers with 4-8 years of teaching experience also showed significantly (p<.05) higher interest toward learning CBL system and its applicability. It was concluded that science teachers perceived CBL system as a promising science teaching method in Korean middle and high schools. However, a science teacher inservice training program for CBL system should be developed in consideration of gender, school level, school location, and years of teaching.
