Purpose - This study examined the effects of intrinsic and extrinsic motivation on employee creativity. Past research has consistently shown that intrinsic motivation is positively related to creativity. Yet conflicting results have been reported about the relationship between extrinsic motivation and creativity. To explore the reason why extrinsic motivation can either help or hurt creativity, we examined the role of contingent rewards as a moderator and tested whether either tangible or intangible rewards contingent upon creative performance significantly impact the relationship between extrinsic motivation and creativity. Research design, data, and methodology - Survey data was collected from employees working for diverse organizations in Korea through online research firm. Only employees who reported their job or organization provided opportunities to use their creativity were allowed to continue the survey. Out of 305 initial responses collected, those with too much missing data were deleted, which finally left 278 responses for statistical analyses. To examine the validity of the measurements, confirmatory factor analysis was first conducted. Next, to test the hypothesized relationships, multiple hierarchical regression analyses were conducted. Results - As hypothesized, both intrinsic and extrinsic motivation had positive effects on creativity. It was shown that contingent rewards did not influence the positive relationship between intrinsic motivation and creativity, but did significantly moderate the relationship between extrinsic motivation and creativity in a way that tangible rewards strengthened the relationship while intangible rewards mitigated the same relationship. Conclusions - This research enhances our understanding on the relationship between motivation type, rewards, and creativity. Intrinsically motivated employees showed a high level of creativity regardless of whether rewards were expected or not. In contrast, extrinsically motivated employees showed more or less creative behavior depending on whether they were expected to have tangible or intangible rewards. As extrinsic motivation is typically associated with tangible rewards such as pay, promotion, etc., tangible rewards were seen to be more effective in promoting creative performance from extrinsically motivated employees than intangible rewards. Our findings make a significant theoretical contribution to reconcile prior inconsistent findings. Furthermore, they provide useful insights for managers and organizations into developing effective strategies for facilitating employee creativity.

Objectives: The purpose of this study was to analyze Influence of stress on oral health and quality of life. Methods: The participants were 172 students from 4 universities located in DaeJeon, South Korea. A questionnaire was administered, assessing the impacts of the general characteristics of the participants, temporomandibular joint (TMJ) symptoms, xerostomia, and halitosis on stress. And oral impacts on daily performance were also investigated. Data were analyzed using the Statistical Package for the Social Sciences 18.0. Results: The level of stress was higher in female, and the causes of stress was reported scholastic achievement, relations with professors, get a job. The students who were higher stress were more conscious of TMJ symptoms, xerostomia and halitosis(p<0.05). Stress was significantly positively correlated with TMJ symptoms (r=0.376, p<0.001), dry mouth (r=0.360, p<0.001), and bad breath (r=0.343, p<0.001). Oral Impacts on Daily Performance (OIDP) scores were significantly positively correlated with dry mouth, bad breath, TMJ symptoms, and stress. Regression analysis showed that 54.5% of the independent variables were related to OIDP scores. Stress and TMJ symptoms exerted a significant effect on OIDP scores. Conclusions: Stress among university students affects oral health and quality of life. Stress coping mechanisms and oral health care education programs should be developed and applied at universities.

Testing is a procedure used to measure a sample of behaviour in order to discover how well a seafarer performs, usually in comparison with others, or compared with identified performance criteria. In this context It is important that the test, in whatever form it is being used, yields consistent results by being valid, reliable and practical. Whilst we can only take a sample of a person's knowledge or comprehension about topic in this way, testing methods do provide a more reliable estimate of performance than most other observational techniques; unsystematic or irregular observation being too unreliable. The method of examination has been specified in the provisions of Regulation 12 of the Decree of the ship officers act as followings. Other necessary matters for conducting oral and written examinations have been set out by the Minister. But written examination is too shortage of period and small number of question to cover the qualification of each level and oral test is just simple and namely Traditionally, written examinations have been provided as the only means for determining the acquisition of knowledge by the mariner. Typically, the examination formats have taken the format of either an essay or multiple choice examinations. Essay items, used in the vast majority of subject examination(not in Korea), consisted of three basic types: situational, descriptive and computational. The level of certificate being examined determined the number and mix of the type of essay questions selected. Oral question has again been used by assessors of seafarer in a wide variety of contexts. Also, oral questioning is often used when observation of performance is undertaken to ask why a certain action has been taken, or to be broaden the scope of what has been observed. At end, Each techniques have their own advantage and disadvantage, so we have to choose some or all of the following techniques, depending upon the certificate, qualification or job for which the trainee is aiming. But in high lank, we have to use both of essay type and multiple choice and with enough time of oral test at least 30 minutes. Who would be the assessor? According to the STCW Code Section A-I/6, instructors, supervisor and assessors are appropriately qualified for particular types and levels of training or assessment of competence of seafarers either on board or ashore, as required under the Convention, in accordance with the provisions of this section.

The aim of this paper was to prove that if the risk level in combined tasks was improved through evaluation of postural load of liquid weight measurement process, the workload level and ratio of exposure time would be changed, and the time of process would be seen concurrently. Background: According to results of epidemiological studies conducted by Korea Occupational Safety & Health Agency, 122 musculoskeletal disorders occurred during 1992 to 2008, in which manufacturing industry covers 96(78.7%) of total. However, this is an insufficient level and only occupies 39% based on the South Korea's manufacturing standard industrial classification(246 industries). Method: Firstly, the number of batches weighed on one day(460min) was investigated based on the work performed and Weight measured weekly. VCR recording was taken based on the level of liquid ingredients prescribed for 1batch using the Camcorder. After dividing a 356 sec video into 1 sec using the screen capture function in Gom player, the job classification was performed by analyzing the change of working postures, which revealed 148 working postures. Time measurement was decided by time of the postures was being maintained. Then, the REBA analysis was performed for the working postures. The ratio of Exposure time was calculated based on the measurement time and REBA Score. In addition, the recommendations were designed and implementation was carried out for the working postures with REBA Score higher than 3. Finally, after the intervention, REBA measurement, time measurement, and ratio of exposure time were calculated for the comparison of works before and after improvement. Results: The number of work elements was decreased by 30.4% from 148 to 103 after improvement. The results of time measurement showed that the time was reduced by 46.3% from 356 sec to 191 sec. And the ratio of exposure time was also improved by 52.1% from 0% to 52.1% after improvement. Conclusion: The reduction of time was found to improve the productivity of management. Furthermore, because the reduction of ratio of exposure time and the improvement of workload level are the improvement of discomfort, it would contribute to the improvement of the worker's psychological working posture. Application: These results would contribute to musculoskeletal disease prevention and management performance. Further studies for other industries would be needed based on this case study.

Purpose - This study attempts to analyze whether or not there are characteristics among the top management of companies that promote corporate performance at venture companies. It investigates the characteristics of the human and social capital that are inherent in top management at a venture company and conducts an empirical analysis of hypotheses examining if these characteristics will affect utilization of the governmental R&D support system as well as affect the firm's initial success. Research design, data, and methodology - This study conducted theoretical and empirical research together to accomplish the goal of the study. The pilot study researched human capital and social capital as the independent variables; the governmental R&D support system as the parameter; and, the initial success as the dependent variable. The empirical study carried out research on the model, establishment of hypotheses, and the statistical treatment. A survey was conducted targeting top management of high-tech venture companies in Daedeok Innopolis; 500 questionnaires were distributed; and, 222 were collected. Results - The human and social capital inherent in top management at venture companies in the early stages of their existence become good evaluation data for those who are invested in similar resources. If top management includes strong human and social capital, access to external resources will be easier; these will have a positive influence on the selection of overnmental support systems; and, this proper support will also have a positive influence on the initial success of the venture company. The results revealed the following. First, it was found that when the educational level and functional background, (the top management human capital), are the output function, top management human capital had a significant influence on selection of governmental R&D support funds. Second, it was found that the internal social capital and external social capital, (the top management social capital), had a significant influence on selection of governmental R&D support tasks. Third, it was found that selection of the governmental R&D support tasks at the start of the venture company had a positive influence on the corporate financial performance such as sales, business profits, and the increase in workers; and, had a significant influence on nonfinancial performance such as market share, competitive position, product competitiveness, and the future product development. Conclusions - Selection of the governmental R&D support system is not recognized as part of the direct sales of a venture company in its early stages, but as it can reduce costs for technical development and helps significantly in creating test products and mass production, it has a positive influence on the company's financial performance and nonfinancial performance as a result. Therefore, companies should take great efforts to frequently be selected as a candidate in the governmental R&D support system, as it can help facilitate R&D that requires extensive funds. As a result, companies can expect effects such as job creation and patent applications and they can advance future product sales.
