This study is an empiriacl analysis of effects of government intervention on the health care delivery system in Korea. The purposes of this study are to find out the effects of government intervention on the per capita national health expenditure(per capita NHE), crude mortality rate(CMR), and institutional efficiency. Here, the institutional efficiency is defined as a formula shown below: log$\frac{100-curde mortality rate }{per capita NHE}$$\times$100. The formula indicates that the instiutional efficiency increases if the CMR and/or per capita NHE goes down. In the meantime the government intervention is measured by six independent variables: I) the degree of social developments, ii) the numberr of physicians per 100, 000 population, iii) the proportion of specialists among the total physicians, iv) the proportion of public expenditure among the NHE, v) the proportion of public beds to the total number of beds, vi) the proportion of physicians working at the public sector to the total number of physicians. In the above six independent variables iv), v) and vi) are the ones that reflect the degree of government intervention. In actual calculation, the two independent variables v) and vi) are integrated into a new variable based on one to one correspondence. The materials used are the time-series data from 1970 through 1990 in Korea. A path analysis and the time-series regression analysis were adopted to estimate and examine the causal relationship between variables involved. And decomposition of the effect of causal relationship is made to find net effect, direct and indirect effect. The major findings are as follows; 1. The effect of public expenditure, number of physicians per 100, 000 population, the proportion of specialists among the total physicians and social development shows a positive relationship with per capita NHE. Only if the government intervention would be counted, the effects of the number of physicians and the proportion of specialists succeed in containing per capita NHE. 2. In additionn to the above four variables, one additional variable, per capita NHE, was also responsible for the reduction of CMR. The factor of social development found to be the most potent predictor of the CMR reduction. However, the CMR reduction due to government intervention was negligible. 3. Meanwhile, the above four variables were found to was have negative effects on the institutional efficiency. The reverse is true when the government intervention is counted. For example, the number of physicians and the proportion of specialists have played a positive role in raising institutional efficiency via goverment intervention. This comes from the factual effect that the increment of institutional efficiency via the reduction of per capita NHE is bigger than via the reduction of CMR.

The purpose of this study is to find out the impacts of VTS on the marine safety and users' opinion on the VTS which have been being operated in the port of Pohang for the last 3 years and is to suggest a guideline to the successful operation of VTS in the future. This study is based upon the questionnaire survey and the respondents include 236 masters/mates of merchant vessels who have visited the port of Pohang and 6 pilots who have been working in the port. From the questionnaire results, this study notes the following conclusions related to the VTS operations. (1) A few of the respondents (mainly foreigners) do not understand the entering procedure of the port and the fundamental concept of VTS. Accordingly, the more active VTS services have to be provided for the mariners. (2) It was found that themost dangerous factors in tehvicinity of the port were the floating materials, fishing nets, andillegal fishing activities inthe fairway. Therefore, the proper surveillance, stricter enforcement of Acts and the instructive education for the fishermen are required to avoid the risks. (3) A majority of the respondents agreed the VTS has contributed to the safety of vessel traffic, and they pointed out ' the assiatances in reduced visibililty conditions' is the most important task of VTS. The amount of 75.6% of the respondents answered that they have experienced the assistance from VTS more than 1 time since the system was established in the port of Pohang . Also 44.2% of the respondents considered they were able to avoid marine casualties such as collision, ramming or agrounding with the VTS assistances. (4) 49.2% of the respondents preferred the passive information services , while, 38.8% of them preferred the positive control advices in the case of encountering any potential risks. VTS iperators have to consider seriously when they provide the positive control advices of ship's course and speed. (5) A majority of the respondents confirmed that the prot and its approaches is suitable for the VTS coverge . To extend the service areas of the VTS and to improve radar detecting ability, the use of radar transponders are seen as the ideal method. (6) A minority of the respondents pointed out 'the improper orders or recommendatinos caused by the poor decision making' firstly, ' the language problem(sea-speaking in English)' secondly, as the deficiency of personal qualification. It seems, therefore, theat the personal efforts of the operators and systematic training programmes for them are necessary to solve the problems.

In today's society, competition of talents is a critical factor of success in modern enterprises due to living in the era of knowledge economy. Also, success of a modern enterprise can be defined by the brand equity or value of the company name defined by general public (functional) and its employees (symbolic). Company brand equity is a subjectively defined by each employee. This article aims to link the relations between employee's perception of employer brand equity to employees' job performance and turnover intention. In order to empirically verify the effects of employer brand on employee's organizational commitment, performance, and turnover intention, study conducted the general employees working for MNC in the field of e-commerce, IT, and Networking business based in China. Total 235 questionnaires were used for the empirical analysis and SPSS 21.0 statistics package was used to analyze the collected data. The results can be summarized as follows: (1) Both the functional employer brand and the symbolic employer brand equity have a significantly positive impact on organizational commitment. (2) Both the functional employer brand equity and the symbolic employer brand equity have a significant positive impact on employee performance. (3) Neither the functional employer brand equity nor the symbolic employer brand equity confirmed the negative relationship between turnover intentions. (4) Organizational commitment play the intermediary role in the impact of employer brand equity on employees' work performance.

This study is a hermeneutic phenomenological study on the experiences of 10 beginning science teachers who have been building positive or negative identity as teachers for the first 3 months. This study was conducted by four steps of the phenomenological qualitative research process suggested by Yeu (2015) based on the study of hermeneutic phenomenology suggested by van Manen (1990). The main data of this study is the transcription data of the telephone interviews collected in consideration of the working area of the research subjects. The main theme is found by categorizing and conceptualizing the meaning of the phenomenon revealed in the data and the process of confirming the legitimacy of the main theme. The results of this study show that the experiences of beginning science teachers that could affect their positive identity as teachers have common moments when they realize that 'I am a necessary person for someone'. On the other hand, the teachers create negative teacher identity when they doubt their teaching competency, particularly when they are not confident about their attitudes toward students or when they are unable to engage students actively in lessons. The results of this study provide important implications for pre-service science teacher preparation program in Korea.

This study was conducted to clarify the mediating effects of self-efficacy and organizational commitment on the level of depression associated with emotional labor and occupational stress of call center representatives. The survey subjects were 486 representatives working in four call centers in D city. Data collection was conducted using structured, self-addressed questionnaires from January 5th to 25th, 2017. The results showed that the depression level of the representatives was significantly higher in the emotional labor and occupational stress groups and higher in the low self-efficacy and organizational commitment groups. The correlations between variables revealed a positive correlation between depression, emotional labor, and occupational stress, but a negative correlation between self-efficacy and organizational commitment. Path model analysis revealed that emotional labor and occupational stress had positive effects on depression, while self-efficacy and organizational commitment was negatively influenced. In addition, self-efficacy and organizational commitment had a mediating effect on emotional labor and depression, while organizational commitment had a mediating effect on occupational stress and depression. Therefore, to reduce the depression level of call center representatives, it is necessary to reduce the emotional labor and occupational stress factors, as well as to have a mental health mediation plan to increase self-efficacy and organizational commitment.

Purpose: In this study, the effect of the eye movement direction on visual function related to accommodation was investigated when playing computer games for a certain period of time. Methods: Total 60 subjects in 20s who had the visual acuity of 1.0 or higher without any ocular disease and accommodative dysfunction were asked to play computer games separately in horizontal and vertical directions for 40 and 90 minutes and then measured their accommodative amplitude, accommodative facility, accommodative lag and relative accommodations. Thevisual function when not doing the computer game was regarded as a control value, and further compared and analyzed. Results: The accommodative amplitude, accommodative facility, accommodative lag and relative accommodations showed the tendency of decrease after the computer game for 40 minutes, and more reduced values of the visual functions were shown when the computer game extended up to 90 minutes except positive relative accommodation. Positive relative accommodation had a tendency to increase slightly after the computer game for 90 minutes. Meanwhile, the change of the visual functions was primarily influenced by the eye movement in horizontal direction rather than by the eye movement in vertical direction during computer game when analyzed by the direction of eye movement. Conclusions: Over all accommodative functions tended to decrease with the extended VDT working time by computer game, and the frequent eye movement in horizontal direction during VDT tasks could be the main cause of eyestrain since the eye movement in horizontal direction rather than vertical direction significantly affected the change of accommodative function.

The purpose of this study was to find out the relationships between emotional labour and depressive symptoms among nurses in university hospitals. Subjects were 514 nurses working at three university hospitals in Daejeon City, and the survey was a structured self- administered questionnaire based from April 1 until May 31 2012. As a results, the level of depressive symptoms by the subjects emotional labour level was significantly higher in the group with higher total average points of the emotional labour than the lower group, As for the correlation between the level of depressive symptoms and emotional labour factors, the depressive symptoms points showed significant positive correlation with the total points of the emotional labour. As a result of hierarchical multiple regression, age, leisure time, coffee consumption, subjective health status, physical burden of work, sense of satisfaction at work, fit to the job and emotional labour were selected as significant variables and related variables effecting the level of depressive symptoms. These variables' descriptive power was 39.4%, especially, it can be seen that 11.0% descriptive power increased by putting the emotional labor variables. The results above imply that there is significant relation between emotional labor and depressive symptoms and various variables such as socio-demographic characteristics, health-related behavior factors and job-related factors. Also, it can be seen that the emotional labour and depressive symptoms showed significant positive correlation. Therefore, the development and implementation of a program to control emotional labor appropriately should be required for lowering the level of depressive symptoms.

This study investigates non-native speakers(NNS) of English use of backchannels with beginner-intermediate learners' use of 'uh', 'um(uhm)', 'and' and 'hm' suggesting a view as a possible pedagogical implication. The initial aim of this study was to learn this phenomenon and observe their conversation patterns to compare with previous studies. Based on the previous findings, the analyzed data using conventional Conversation Analysis (CA) methods indicate the possible presence of L1 topic markers, '-un' and '-nun' in the form of L2 backchannel tokens when uttered by beginning and intermediate level speakers of English and the presences of L2 backchannel tokens appear only in front of noun phrases. Additionally, these same words with these tokens and when translated back to Korean also require topic markers of '-un' and '-nun.' Finally, This study discusses possible pedagogical implications with the initial analysis of backchannel tokens for Korean EFL learners. In addition, the ultimate goal of this study is to refine this analysis with follow up experiments to validate this investigation into a working hypothesis generating discussions of this backchannel phenomenon from being viewed as a hindrance to as an positive influence that needs to be understood.

The purpose of this study is to verify the effects of team trust and cooperative behavior on the food-service employees' perceived service performance as well as the moderating effects of team competency and other department support in the relationship among the team trust, cooperative behavior, and service performance of food-service employees. We conducted a survey of 1,080 food-service employees working in 8 hotels and 4 food-service stores located in Seoul, Gyeonggi, Song-do, Gyeongju, and Busan, and 841 food-service employees were employed for statistical analysis except unreliable responses. As a result of a SEM (structural equation modeling) analysis to confirm hypotheses, it was found that team trust (leader trust and co-worker trust) had a positive effect on the cooperative behavior. In addition, the cooperative behavior had a positive influence on the food-service employees' perceived service performance. Also found was the moderating effect of other department support in the relationship between the cooperative behavior and food-service employees' perceived service performance. Based on the research findings, we discussed its academic and practical implications, and suggestions on the future research.
