The purpose of this study is to investigate the factors affecting innovation capability and innovation performance of midsize company entering overseas market. More specifically, in terms of managerial, organizational, and employee - level factors, we set leadership, operating system, and taking charge at work as variables influencing innovation capability and tried to understand the effect of innovation capability on innovation performance through empirical studies. In addition, we examined the differences in the influence factors on innovation capability and the effect on innovation performance in the home country and overseas countries. As a result of the empirical analysis, all of the influence factors had a positive effect on the innovation capability and the innovation capability had a positive effect on the innovation performance. The degree of influence was in the order of operating system, leadership and taking charge at work. In China, there is no significant difference in the order of operating system, leadership and taking charge at work. In the case of Korea, operating system and leadership have a positive effect, but the employee's taking charge at work does not affect innovation capability. The results of this study are as follows. First, it is necessary to enhance innovation capability in accordance with local characteristics. In Korea, there are additional activities to induce employee's taking charge at work is required for improved innovation capability and innovation performance.

Among various fuel cells, solid oxide fuel cells (SOFCs) offer the highest energy efficiency, when taking into account the thermal recycling of waste heat at high temperature. However, the highest efficiency and lowest pollution for a SOFC can be achieved through the sophisticated control of its constituent components such as electrodes, electrolytes, interconnects and sealing materials. The electrochemical conversion efficiency of a SOFC is particularly dependent upon the performance of its electrode materials. The electrode materials should meet highly stringent requirements to optimize cell performance. In particular, both mass and charge transport should easily occur simultaneously through the electrode structure. Matter transport or charge transport is critically related to the configuration and spatial disposition of the three constituent phases of a composite electrode, which are the ionic conducting phase, electronic conducting phase, and the pores. The current work places special emphasis on the quantification of this complex microstructure of composite electrodes. Digitized images are exploited in order to obtain the quantitative microstructural information, i.e., the size distributions and interconnectivities of each constituent component. This work reports regarding zirconia-based composite electrodes.

The objective of this study was to identify the current status of use and respective work scopes of dental hygienists and nursing assistants as perceived by dentists, thereby obtaining a model for how to efficiently use oral health assistance personnel. This study was based on a self-reported survey administered to a total of 126 dentists. The following findings were observed. Where competition among neighborhood clinics was relatively high, nursing assistants tended to be used as a resource to assist dental hygienists, whereas where it was relatively low, they were more likely to be considered to work as full substitutes for regular dental hygienists. Looking at the scopes of practice, dental hygienists were allowed to deal with matters of preventive care, oral health education, and health insurance claims. On the other hand, nursing assistants were allowed to be in charge of taking X-ray pictures from the outside and inside of mouth and keeping medical devices clean and safe. This study is expected to contribute to establishing more reasonable oral heath personnel structure design decisions.

Injuries to the menisci occur in a variety of ways, most commonly with a twist, pivot, squat, or valgus stress to the knee. Tear patterns are classified to longitudinal, horizontal, or transverse features according to the mechanism of injury. Work-related meniscal tear usually occurs with a repetitive usage of the foot, hence it can be classified as a cumulative traumatic disorder. We found a 47 year-old female worker who had been taking charge of repetitive foot-switch stepping for 8 years. She suffered from pain in the right knee since 5 months ago. Tenderness along the medial joint line of the right knee was observed and pain was aggravated with full flexion of the right knee. On magnetic resonance imaging, high signal intensity was observed at the posterior horn of the medial meniscus of the right knee. Degenerative longitudinal and transverse complex tear in the medial meniscus was observed on arthroscopy. Arthroscopic partial meniscectomy was performed. We surveyed the work process and the health status of co-workers. It turned out that the work process was compatible to injure the meniscus and nine out of fourteen co-worker(64.3%) complained pain of the knee. No other factors related to her meniscal tear could be found except for the situation at her work. Therefore, we conclude that meniscal tear is related to the repetitive stepping of foot switch.

The study collected 251 copies, which showed the collection rate of 83.7%, and analyzed 247 copies (82.3%) excluding 4 copies of insincere answers. As a research tool for measuring job satisfaction the study used a tool employed for research into the job satisfaction of physical therapists who work at medical institutions in Gwangju, Jeonnam, and Jeonbuk by Kim Hee-Gwon(1992) and research regarding job satisfaction by Jeong Jeong-Hee(2004) as well as research regarding the factors of job satisfaction by Flippo(1980) & Seberhagen(1970) after adjusting the research tools to the purpose of the study. Also for questions about work stress, the study employed nurses' job stress measurement tool developed by Kim Mae-Ja and em Mi-Ok(1984) by modifying the tool to the purpose of the study, and for a measurement tool for reaction to stress, the study used a tool employed for research into reaction to stress of nurses at general hospitals by Choi Eun-Deok(2005) without modification. For data analysis, the study used the SPSS12.0 as a statistical method, and then used t-test or ANOVA for verifying actual numbers, percentile, average :score, standard deviation, rank, and difference. Also, the study conducted which is a post-test method for variables that show a significant difference at the level of p<.05 level after the analysis. The findings include the following. 1) The respondents' job satisfaction score was 3.21 points on the average (out of 5 full points). The peer relationship ranked the highest, posting 4.02 points on the average, and the job satisfaction with rewards was proven the lowest, posting 2.51 points. For the job satisfaction level by characteristics, there were significant differences (p<.05) in gender, hospital type, weekly working hours, monthly working days, number of patients per day, department in charge of therapy, and number of peers, and there was no significant difference in characteristics other than that. 2) The respondents' work stress score was 2.72 points (out of 5 full points) on the average. The respondents were shown to be under the highest stress when they suffered from excessive workload, posting 3.49 points on the average, and they were shown to be under the least stress when they had a conflict with peers at another department, recording 1.90 points on the average. for the job stress level by the characteristics of job, there was a significant difference in the reflection of job assessment(p<.05). 3) 1n respondents' reaction to stress, most of them were shown to make efforts in coping with stress, posting 2.80 points (out of 5 full points). For their experience of being wider stress, they answered that 'they felt depressed (2.85 points)" for their experience of coping with stress, they answered that 'they were indifferent to it or thought about something else' (2.62 points). Also, for their efforts in coping with stress, they answered that 'they were motivated to remove their strain by taking leave, playing, or using their preferences' (3.52 points), which ranked higher. For the level of reaction to stress by characteristics, there were significant differences by age, gender, marital status, total service years as a physical therapist, monthly working days, and department in charge of therapy(p<.05). It is necessary to offer correct information by conducting an in-depth analysis of the stressful situations of physical therapists who exert efforts in rehabilitating patients at hospitals by factor, and seeking management plans based on the research results. Also, it is necessary to develop a program for coping with stress efficiently for removing stress and to conduct research into the understanding and cooperation of administrators and persons in charge of physical therapists for reducing physical therapists' stress at hospitals.

In order to optimize the performance of a lithium-ion battery, a performance prediction modeling technique that considers various degradation factors is required. In this work, mathematical modeling was carried-out to predict the change in discharging behavior and cycle life, taking into account the cycle aging of lithium-ion batteries. In order to validate the modeling, a cycling test was performed at the charge/discharge rate of 0.25C, and discharging behavior was measured through RPT (Reference Performance Test) performed at 30 cycle intervals. The accuracy of cycle life prediction was improved by considering the break-in mechanism, one of the phenomena occurring in the BOL (beginning of life), in the model for predicting the cycle life of lithium-ion batteries. The predicted change in cycle life based on the model was in good agreement with the experimental results.

The purpose of this study was to serve as a basis for more efficient dental hygienist human resources utilization and for determining some of the right directions for supplementary education for dental hygienists, by examining how they actually worked and what they thought of job-related things. The subjects in this study were 537 dental hygienists who participated in a seminar by the Korea Dental Hygienist Association. After a survey was conducted, the following findings were given: 1. 50.2% of the dental hygienists investigated completed legally required eight-class education. Those who worked in clinics took less supplementary education classes than the others in the other types of dental institutions. The main reason they didn't receive supplementary education was financial burden and uncooperative employers. 73.2% took supplementary education at the association or its branches. The association was most favored by those in clinical sector as a place that provides supplementary education, followed by its branch and university in the order named. And the dental hygienists in public health sector preferred university most, and the next best favored one was the association and its branch in the order named. Those in clinical sector hoped to acquire clinical information on patient management, implant or aesthetics, and the dental hygienists in public health sector wanted to learn about health administration, public oral health operations and oral health education, which were different from what those in clinical sector wanted. 2. Regarding the period of service, 492% had worked for three years or more. This fact suggested that their service term and average age continued to grow. And they thought they would decide the retirement time on their own. 3. The most common yearly income ranged from 12 million won to 16 million won(40.7%). For-those in clinics, yearly income was 14.36 million won, and that of the dental hygienists who had worked for less than 3 years was 12.90 million won. 4. The Korea Dental Hygienist Association was most required to protect the rights and interests of the members and offer new knowledge and technology. 5. The largest group of them were engaged in patient management, and this type of job also was the most favored one for them to do. The greatest number of the dental hygienists in public health sector were in charge of dental treatment. 6. Concerning their turnover rate, 492% had never changed their occupation. Specifically, 70.0% of the respondents who had worked for less than 3 years had have no experience to do that. The time constraints for self-development and conflicts with other workers were the cause of their turnover. Those in dental hospital and general hospital changed their occupation chiefly due to the lack of time for self-development, and for the dental hygienists in clinics, the conflicts with other workers were the main reason. The above-mentioned findings suggested that the way the dental hygienists looked at things was undergoing change. The service area made a difference to their preference for the type of supplementary education and institution in charge of it, as those in public health and clinical sectors had a different opinion. And the dental hygienists in clinical sector had a different opinion as well, according to service area, about salaries, reason of not taking supplementary education, preferred type of supplementary education, cause of turnover, and type of occupation to which they hoped to change employment. To utilize and supply human resources in a more stabilized manner, job description should be more segmented, standardized and classified clearly, and dental hygienists should be motivated to perform their substantial jobs, including oral disease prevention, oral prophylaxis and oral health education. To make it happen, it seems that dentists are required to have a clear understanding of dental hygienist job and to change the way they look at it.

This study examined the extent to which childcare methods of infant classroom childcare teachers who respect infant rights in the everyday teaching curriculum at day-care centers occurs. To achieve these objectives, a questionnaire survey was conducted on 210 infant classroom childcare teachers who were in charge of the day-care center classrooms located in [G] city of [J] province. The results of the research confirmed that first there were no statistically significant differences when verifying the extent to which childcare methods of infant classroom childcare teachers who respect infant rights in the everyday teaching curriculum at day-care centers according to the final education level, professional experience, age, and education major of the infant classroom childcare teacher. On the other hand, the results confirmed that when analyzing for arrival time for infant classroom childcare instruction at the day-care center and for the time spent taking the infant to and from the bathroom, the infant classroom childcare teachers who had graduated from 2 year colleges showed more respect for infant rights compared to that of infant classroom childcare teachers who had graduated from 4 year universities, and for the arrival time for infant classroom childcare instruction at the day-care center and nap times, the infant classroom childcare teachers who were above 50 years of age showed more respect for infant rights compared to that of infant classroom childcare teachers who were in their 30s and 40s. The results of the research confirmed that there were statistically significant differences for both the age and education major of the infant classroom childcare teachers. When examining each of the sub-factor, the age of the infant classroom childcare teachers, respect for the infant's opinion, respect for individuality, and for information provision, infant classroom childcare teachers older than 50 years of age were shown to exercise a higher level of respect for the infant according to the rule of prioritizing the infant compared to infant classroom childcare teachers in their 30s and 40s, and infant classroom childcare teachers who majored in infant education-related majors exercised a higher level of respect for the infant for respecting freedom and autonomy compared to that of infant classroom childcare teachers who majored in welfare and childcare-related fields. The results of the research confirmed a statistically significant static correlation between the two related variables. Therefore, this suggests that the more childcare methods of infant classroom childcare teachers who respect infant rights in the everyday teaching curriculum at day-care centers, the more childcare methods of infant classroom childcare teachers who respect infant rights occurred according to the rule of prioritizing the infant. These results can be used to establish both quantitatively and qualitatively an excellent and balanced respect for infant rights.
