This study is to present basic materials to further selection of details of health care service bill and supply resources by analysing the consciousness of radiological technologist and dental hygienist about health care service bill proposed for prevention and early diagnosis of a disease through the improvement of living habit. Subjects were 359 of dental hygienists and radiological technologists investigated from 2010 July to September for three months. As the result, recognition level on health care service bill or its details was less than 30.0% but the opinion that health care service bill is necessary was 78.0%. In its additional item, radiological technologist hope to be maintained currently, and 82.3% of the dental hygienist hope to be added, their prefered additional item was dental disease. A dominant opinion was that dental hygienist and radiological technologist as a service supply personnel were included, and their intention to participate was 8.1 in average. In conclusion, the health care service bill is indispensable, but more systematic study is required based on collecting various opinions about major contents and service provider. Particularly it is inevitable to include the health human resources such as experienced dental hygienist and radiological technologist who had completed the regular course of health education and are having continuous clinical discipline.

This study aims to confirm the effect of different types of interpersonal stress factors of private security officers that are prevalent in the course of carrying out their duties on job satisfaction and turnover intention. The authors have examined 175 of the 200 survey questionnaires distributed to the employees of private security firms located in Seoul and Gyeonggi Province in December 2012. The result of the analysis indicates that the primary source of stress in the private security officers is the interaction with customers, followed by the relationships with colleagues and superior officers. In addition, colleague-related stress is found to be the only interpersonal stress factor with a statistically significant negative effect on job satisfaction, while both the stress from the relationships with colleagues and superior officers are positively correlated with turnover intention. Furthermore, the colleague-related stress is revealed to mediate job satisfaction which has a statistically significant effect on turnover intention. The result from the study emphasizes the importance of managing the interpersonal stress in private security officers and confirms the necessity of effectively handling the stressful situations in the relationships with colleagues. Moreover, in order to raise job satisfaction levels and minimize turnover which is vital in accomplishing the goal of each organization, causal factors of the stress need to be recognized and handled appropriately. This will provide the future research with an insight into the effective interpersonal stress management and examining other factors of job satisfaction and turnover intention of private security officers.

A number of schools have introduced the Reward and Punishment Mark System. It has been applied to children at school in order to minimize the ill effects that are often caused by physical punishment. In this case, teachers have caused problematic issues in the course of student life guidance at school. However, the application of the personal Reward and Punishment Mark System raises many other questions as well. Accordingly, there is the necessity of making up for its weak points on the systematic level. The purpose of this study is to understand the Effect of the Collective Reward and Punishment Mark System, as a substitute punishment to the physical punishment, applying the reward and punishment mark system not to an individual but to a group. The Collective Reward and Punishment Mark System for the upper grade students of primary schools showed a positive effect which assists their adaptation to school. To put it more concretely, according to the characters of the study subjects, the system has proved that boy students are more positively affected than girl students. It has been also revealed that those students in the fourth grade experience a positive change in all areas of the adaptation to school, while those in the fifth and the sixth grade were negatively affected. Moreover, those who hold a lower rank in respect of grade achievement experienced a more positive change than those standing among a high rank. It is expected that the Effect of the Collective Reward and Punishment Marks System, on the basis of the study, possesses affirmative intervention on the field.

The purpose of this study is to make analyses on the importance and performance of the foodservice management, foodservice service, and the courses related to coffee in the colleges providing a coffee related curriculum, in order to determine which courses are required in the education programs for employees needed by the coffee restaurants as the employers' viewpoint. The analysis methods were frequency analysis, T-test and IPA analysis. The result are as followings. First, the performance was lower than the importance when it comes to importance and performance with the coffee related courses recognized by the staff in the coffee restaurants, particularly with a big gap in the theory of cost control and coffee theory. Second, in the IPA analysis of the importance and performance of the curriculum, quadrant - I as a weak item includes the cost control, foodservice marketing, and coffee theory courses. Quadrant - II includes the foodservice, coffee extraction practice, Espresso, Caffe Latte and Cappuccio, and Latte Art courses. Pertaining to the quadrant - III are those courses lack of the necessity, including the foodservice management, foodservice franchise, practical English in service, and coffee roasting. Quadrant - IV contains those course of less importance but of higher performance such as the practicum work experience. As part of limitations of study, specialties of staffs working for coffee franchise shops were not reflected due to lacking in pre-conducted studies and the samples couldn't be recognized to represent all coffee franchise shops since the sampling districts were restricted only to Seoul metropolitan area.

Purpose: The purpose of this study is to evaluate the effect of a VR (Virtual Refractor), which is a simulator for a PR (Practical Refraction), as an educational tool. Methods: Twenty four third year students enrolled in the department of visual optics volunteered for VR education. Each student attended a VR training course and practiced with the VR by themselves. One month later, each student tested three virtual subjects on the VR and one real subject on the PR and were given a performance score for each refraction. And the scores for the virtual and practical refractions were compared. In addition, a self-report questionnaire based on a five point Likert-scale was designed, consisting of domains such as spontaneous participation, contribution for the refraction, confirmity of the VR and PR, and necessity of the VR. Results: The Spearman's correlation coefficient between the testing score of the practical and virtual refractions indicated a significantly correlation (R=0.71, p<0.001). In the questionnaire, the mean score of the domains was 3.67${\pm}$0.96 and it indicated that students expressed that using the VR was beneficial. The correlation value among these domains was a high significant level, 0.91~0.68 (p<0.001). Conclusions: Although the VR required certain improvements in its concentration and systematic approaches for practical situations, it showed a high correlation between the VR and the PR and represented a positive evaluation in the PR.

The optotypes widely used as a necessity in the course of optometry are the world authorized versions which contain items such as the Landolt's rings, Snellen's chart and also Arabian numbers, Korean letters, Pictures and so on. In Korea, the Hahn-chun-suk test chart has been In use generally alolng with Chung-san test chart and Jin-yong-han test chart also in use on the wall. But these sort of test charts hung on the wall have some problems such as the difference in test results owing to the rate of illumination and so a more accurate method is required. To solve the problem of inaccuracy in optometry, the projected type of charts with digital instrument such as the beam projector has been developed lately. This chart projector with consistent high resolution and the ability to provide various charts can help eye examiner perform effective examination and thus is looked positively upon as the automated total optometry system. So in this study our purpose is to examine the accuracy of the projected chart. It was done by comparing it with the frequently used test chart. The results of experiment are as follow. When the projected chart was used, cases that subject read charts one step higher were 10%, two step higher 2% than perfectly corrected vision. When Han-chun-suk test chart was used, cases that subject read charts one step higher were 12%, and two step higher were 4%.

This study examined the causal relationship between work environment and job satisfaction/turnover intention through statistical analyses using the statistics programs SPSS(18.0) and AMOS(18.0) of over 268 business owners operating small sized Chinese restaurants in the Busan and Gyeongnam area. Research results found that among the business owners of small sized Chinese restaurants, 130 were owner/chefs (48.5%), 63 engaged in hall serving (23.5%), and 75 were in delivery (28.0%). It was also found that while the physical environment had a positive effect on work pride and economic satisfaction, sale stress had no effect on work pride and economic satisfaction. In addition, the physical environment and mental labor environment showed a positive effect (+) on turnover intention, although job satisfaction (work pride, economic satisfaction) showed a negative effect (-) on turnover intention. Such result leads to the conclusion that for business owners of small sized Chinese restaurants, sale stress experienced during the course of business serves as a factor weakening job satisfaction while increasing turnover intention to a greater extent of the physical environment (kitchen facilities and hall facilities). Thus, it seems that practical business training, such as service training, is a greater necessity for business owners of small sized Chinese restaurants, as opposed to an improvement of restaurant facilities.

Based on the stakeholder theory, this paper analyzes a clash of standards in Korea's Electric Vehicle(EV) market, particularly between an EV charging standard and a smart grid communication standard in 2012~2013. For charging, EV is connected with the electric power grid and simultaneously exchanges data regarding the charging status. When EV is connected with the power grid, a clash between two standards may arise. It actually happened when BMW entered into the Korean EV market with the DC Combo charging system. In that course, the frequency interference occurred between the EV data communication technology adopted by BMW and the AMI(Advanced Metering Infrastructure) for the smart grid system in Korea. Standardization of Korea's EV charging systems was required to solve this problem. However, it had been delayed due to the confrontation between various stakeholders involved in the process of standardization. It lasted until the DC combo was accepted as one of the Korea EV charging standards(KSAE SAE 1772-2040, 2014.1) by KSAE(The Korea Society of Automotive Engineers) in January 2014. This is an interesting case in the age of convergence. As it deals with the standard competition not among EV standards, but a clash between the EV industry and the smart grid, i.e. electric power industry, it addresses the necessity to consider standardization processes between different industries. This study draws on the stakeholder theory to analyse the dynamics of the standard clash between EV charging systems and the smart grid system, which is a unique example of standard clash between different industries. We expect such clashes to increase in the age of convergence.

In this article, another literatures that original Korean own red pepper (Gochu) was cultivated from ancient years and there were many other varieties of Gocho in Korea were shown. The first book where Gochu was appeared as written in Hangul (Korean own character invented by King Sejong in 1433) was Hunmongjahoe (訓蒙字會) written by Choi Sejin in 1527. However, many books where cho(椒) indicating Korean red pepper (Gochu) was described before Hunmongjahoe. This is consistent with Hongjaejonso(弘齋全書, 1799). King Jungjo asked Kim Dalsun about the type of Cho(椒) in Hongjaejonso, Kim Dalsun answered to King Jungjo that there are many types of Cho such as Chokcho(蜀椒), Jincho(秦椒), Dancho(丹椒), Daecho(大椒) and Hocho(胡椒). When common characteristics in Chokcho, Jincho, Dancho, Daecho and Hocho in Hongjaejonso were studied, it was found that these Chos had one word in common "Gocho(고쵸)" in the Korean translation. Also several Chos such as Buncho(蕃椒), Nammancho(南蠻椒), Mancho(蔓椒) were characterized as Gocho in ancient books. In conclusion there were several Chos such as Chokcho, Jincho, Dancho, Daecho, Hocho, Buncho, Nammancho, Mancho, etc indicating the various types of Cho, and these were all written as Gocho(고쵸) in the Korean character. An original Korean Gocho should be cultivated in Korean peninsula. Several different types of Cho were imported during the course of trade with foreign countries, and these foreign Chos called as Buncho(蕃椒), Nammancho(南蠻椒), Mancho(蔓椒) by discriminating original Korean Gocho(고쵸). The original name of Gochu(고추) is Gocho. Later the Chinese character for Gocho(苦椒) invented in response to the Korean character of "Gocho(고쵸)" by necessity.
