The purpose of this study is to investigate the relationship between the acceleration of vibration by the powered hand tools used in the shipbuilding industry, and to develop the prospective prevalence model for the hand-arm vibration syndrome among the shipbuilding workers.The acceleration levels and frequencies of six types of grinder were measured using the ISO5349 method along with the time of exposure to the vibration from the powered hand tools. Medical examination for 114 workers were performed using the cold provocation test. Comparisons were made between the estimated prevalence of hand-arm vibration syndrome from ISO5349 and the observed values from the medical examinations. By multiple regression, we developed the prospective prevalence model of hand-arm vibration syndrome produced by the hand tools used in the shipbuilding industry. 4 hour-energy-equivalent frequency-weighted accelerations were $6.23m/s^2$ in the grinding job done after welding, and $13.39m/s^2$ in the grinding job done before painting. The mean exposure time while holding powered hand tools was 4.64 hours. Prevalence rates of Raynaud's Phenomenon were 12.04% in the grinding after soldering, and 42.9% in the grinding before painting measured using the ISO5349 method. After exposure to vibration for 10.79 years, about a half of the workers in the grinding after welding could developed Raynaud's Phenomenon. For the workers in the grinding before painting, the latency was 5.02 years. The ISO equation for dose response relationship was not significantly correlated with observed recovery rates of finger skin temperatures, blood flows and amplitudes of nerve conduction velocities. A multiple regression model for dose-response relationship was proposed from the results. Recovery rate of the skin temperatures = -0.668+ 0.337 ${\times}$ 4 hour energy equivalent frequency-weighted accelerations + 0.767 ${\times}$ duration of vibration exposure(years) The validity was proved by multiple regression analysis after correlation transformation and regression results based on model-building data and validation data.

In this study, various conflicts in the maritime police organization were diagnosed and police subculture, which is different from dominant mainstream maritime police culture, was concluded to cause conflicts. In addition, maritime police conflicts and conflicts due to the balance, confrontation, and contradiction between bureaucratic and democratic values in the maritime police organization itself are discussed. The results of analysis on the effects of Maritime police subculture on organizational conflict are as follows: First, the influence of cynicism on functional conflict was explored. The higher the level of lies of the persons under investigation, the more functional conflict appeared. Also, if a person showed a low level of credibility among the police, this also led to functional conflict. In addition, if an individual showed low levels of cooperation and credibility with the police, this resulted in hierarchical conflict. Second, the influence of machismo on functional conflict was also explored. It was found that female officers experienced conflicts because of poorer job performance compared to male counterparts. In hierarchical issues, female officers experienced conflict over the reduced scope of tasks assigned to them and lower job performance ability. Third, the effect of non-acceptance of change in functional conflict was not statistically significant. An aggressive attitude toward crime control and rejecting jobs unrelated to crime influenced functional conflict, and an aggressive attitude and performing jobs unrelated to crime lead to functional conflict.

Occupational ethical awareness is a system of norms and standards of behavior and an important component of professionalism that affects organizational performance and commitment. The purpose of this study is to examine the mediating effect of professionalism on the relationship between job ethics and organizational commitment of civil servants. A survey was conducted on 300 central government officials with more than one year of employment. 261 copies were used for the final analysis. The results are as follows. First, the vocational ethics of civil servants had a significant effect on professionalism. The higher the years of service, the higher the level of ethics. Second, the work ethic of public officials had a significant effect on organizational commitment. These results can be interpreted as the internal commitment of civil servants to the state of work ethic. Third, the mediating effect of professionalism was verified in the relationship between public morality and organizational commitment. Based on these results, the public ethics of public servants are the basis for accepting public values and goals. Vocational expertise with embedded codes of conduct and value systems influences organizational commitment. As a practical implication for improving the ethical ethics of public officials, education programs for improving ethical consciousness according to job titles and duties were provided, and the ethical ethical competence was presented.

Objectives: It is difficult to identify exposure factors in the semiconductor industry due to low exposure levels to hazardous substances and because various processes take place in fabrication (FAB). Furthermore, a single worker often experiences a variety of job histories, so it is difficult to classify similar exposure groups (SEG) in the semiconductor industry. Therefore, we intend to develop a new exposure index, the period of working in FAB, that is applicable to the semiconductor industry. Methods: First, in specifying the classification of jobs, we clearly distinguished whether they were FAB workers or non-FAB workers. We checked FAB working hours per week through questionnaires administered to FAB workers. We derived an exposure index called FAB-Year that can represent the period of working in FAB. FAB-Year is an index that can quantitatively indicate the period of working in FAB, and one FAB-Year is defined as working in FAB for 40 hours per week for one year. Results: A total of 8,453 persons were surveyed, and male engineers and female operators occupied 90% of the total. The average total years of service of the subjects was 9.7 years, and the average FAB-Year value was 6.8. This means that the FAB-working ratio occupies 70% of total years of service. The average FAB-Year value for female operators was 8.4, for male facility engineers it was 7.7, and for male process engineers it was 3.5. A FAB-Year standardization value according to personal information (gender, job group, entry year, retirement year) for the survey subjects can be calculated, and standardized estimation values can be applied to workers who are not participating in the survey, such as retirees and workers on a leave of absence (LOA). Conclusions: This study suggests an alternative method for overcoming the limitations on epidemiological study of the semiconductor industry where it is difficult to classify exposure groups by developing a new exposure index called FAB-Year. Since FAB-Year is a quantitative index, we expect that various approaches will be possible in future epidemiological studies.

This study was conducted to present comprehensive professionalism measurement tools suitable for hospital administration staffs. The study used measurement tools related to the psychological and behavioral characteristics of individuals used in prior studies for administration staffs at general hospitals and hospitals. Factor analysis and reliability analysis were conducted to verify the validity and internal relevance. As a result of the analysis, it was concluded that composed of 5 factors, and that the total reliability was 94.4%, which was very reasonable as a comprehensive professionalism measurement tool. Therefore, each component was defined as Confidence of Job performance, Salary Adequacy, Pride in Duties, Ability to achieve work goals, and Work Autonomy in order to provide a clear meaning. Professionalism from a modern perspective is a broader concept than traditional professionalism, including the subjective perceptions of job values and individuals' their abilities. Therefore, comprehensive professionalism measurement tools presented in this study will be very suitable and useful for hospital administration staffs.

The purpose of this study was to identify work-family balance values(work-family centrality, marriage value, child-care value, work value etc) in Korea, Japan and U. K.. Moreover, This article investigated the attitudinal generational gap in each countries. Participants were 311 Korean, 324 Japanese and 322 English married working women, who were in the thirties fifties. The major findings of this study were as follows. Compared to Japan and U. K., Korean married working women were more work-centered and likely to seek for extrinsic work value as well as intrinsic work value. While they were highly thought that a woman should work despite of her marriage, it was also strongly concerned if their work negatively affected family life, they should be better to quit their job. These results showed that conservative-liberal values were coexisted in Korean participants. Secondly, U. K. participants were more centered on the family-oriented value and thought that women were not necessary to work in work-family conflict, in comparison to Korean and Japanese. As a result of cluster analysis, they were a lot distributed in 'woman's family care oriented group' which was weigh on woman's role as a family care giver as well as 'family value oriented group'. Thirdly, Japan participants not only were less family-centered but also less work-centered. In the similar vein, they were less motivated and oriented to all of intrinsic and extrinsic work values compared with participants in Koran and U. K. On the other hand, Japanese participants, in sharp contrast to Korean, had a liberal viewpoint in work-family related values, such as woman's work, career break caused by work-family conflict, and family values. We were trying to interpret these results in consideration of socio-economic-politic as well as psychological aspects.

Purpose - As the importance of salesperson attitudes and behaviors enhancing customer perception and loyalty have increased, many retail companies put emphasis on internal marketing activities. The issue also has captured the interest of academics, but most of the previous research tends to be limited to investigating antecedents of salesperson job satisfaction and commitment. Based on the consumer-brand relationship concepts, this study aims to examine the effects of the salesperson-brand relationships on customers' service evaluation and store loyalty. Research design, data, and methodology - In a structural equation model, it is hypothesized that salesperson brand identification influences salespersons' brand trust and affect, which are the two dimensions of consumer-brand relationships. Salespersons' brand trust and affect are expected to increase salespersons' customer orientation, which in turn influences customers' service evaluations and store loyalty. To test this hypotheses a set of data collected from department stores in Seoul is utilized. Results - First, it was found that salesperson brand identification is a significant antecedent to salespersons' brand trust and affects, the two dimensions of salesperson brand relationships. Second, salespersons' brand trust and affect were found to enhance salespersons' customer-oriented behaviors. Third, salespersons' customer orientation showed a significant effect on customers' service evaluation. When a salesperson makes more effort to provide useful information for fulfilling customer needs, customers evaluate the salesperson's service more positively. Finally, customers' service evaluation had a positive impact on customers' store loyalty. Conclusions - This study provides significant academic and practical implications. First, based on the theory of consumer-brand relationships, the concept of salesperson-brand relationships was introduced and found to be an effective motivator of salespersons' customer oriented attitudes and behaviors. Therefore, the two dimensions of brand relationships, brand trust and affect, should be considered as the critical factors both in developing theoretical research and improving long-term company performance. Also, internal marketing activities should focus on maximizing employees' brand identification. That is, retail companies need to put emphasis on sharing their brand values and personality with internal customers to strengthen the brand relationships with salespersons and to enhance customer responses.

Purpose: To present necessary data for improvement in communications between health professionals in as characterized by nurses' communications. Methods: This study was a descriptive survey research design with a survey of 1,510 registered nurses working in general hospitals (of at least 1,900 beds) in Seoul. A questionnaire on communication in the ICU, nurse-physician and nurse-nurse, was used. Data were collected from January 9 to 20, 2012, and the response rate was 85.0%. Results: Cronbach ${\alpha}$ values ranged from .75 to .89, except for .59 for accuracy (nurse-physician), with .89 overall. The highest mean score was for perception for timeliness [$3.83{\pm}.57$], followed by shift communication (nurse-nurse) [$3.64{\pm}.66$], openness (nurse-nurse) [$3.64{\pm}.65$], accuracy (nurse-nurse) [$3.14{\pm}.61$], openness (nurse-physician) [$2.90{\pm}.75$], understanding (nurse-physician) [$2.82{\pm}.65$], and accuracy (nurse-physician) [$2.70{\pm}.59$]. Subscales of openness, understanding, and shift communication were strongly associated with communication satisfaction. The general characteristics of nurses with different perceptions of communications included age, clinical experience, work pattern, and department. Conclusion: Proactive activities to improve accuracy, openness and mutual understanding between physicians and nurses are required for patient safety. Further studies are also needed to reassess communications and evaluate the relationship between patient outcomes and nurses' job satisfaction after application of strategies to improve communications.
