Objectives : The purpose of this study was to investigate regional commitment index(RGI) of hospital in Korea, and the relationship RGI and hospital characteristics, such as foundation, region, size. Therefore, we are to suggest fundamental information to make and evaluate healthcare resource policy in hospital- and government-level. Methods : The 'Patient Survey 2002(administered by Ministry of Health and Social Welfare(MOHW)' was analyzed. We selected the patient data of the hospitals above 100 beds. Then, we calculated the RGI, number of same cases divided by all cases in each hospital. By using SPSS/win ver 14.0, statistical analysis such as t-test, ANOVA, correlational and regression analysis was carried out. Results : The results are as follows. 1. Overall mean and standard deviation of RGI were revealed as 0.805${\pm}$0.225 in inpatients, and 0.871${\pm}$0.184 in outpatient. The median of inpatients' and outpatients' RGI were 0.890 and 0.933. The RGI of inpatients of private hospitals were revealed significantly higher than that of the public(public: 0.727, private: 0.822). However, outpatients' RGI was not revealed as significantly different. 2. The RGI of general specialty hospitals were significantly lower than others, therefore we could think that more inpatients and outpatients of general specialty hospitals flowed in from others province or metropolitan cities than other hospital types. 3. The RGI of hospitals holding above 400 beds were significantly lower than others in inpatients and outpatients. 5. The RGI of hospitals were significantly different among sixteen province and metropolitan cities. The RGI inpatients of Gwangju and Daejon metropolitan city were lowest sub-group(0.659, 0.664), and the RGI inpatients of Jeju was revealed as highest, 0.979. 6. Available beds, total doctors, and total employees were negatively correlated with RGI of inpatients and outpatients. 7. The significant influencing factors to RGI of inpatients and outpatients were appeared samely such as available beds, wide healthcare region, hospital size, and foundation type. Conclusions : It is considered that RGI of hospital represent competitive power in healthcare market. Also, the competitive advantage and quality of hospital clustered by characteristics could made out by RGI. Therefore, the results of this study would be useful to develop and evaluate hospital policy of individual hospital or local government.

This study was conducted to research into the recognition level of employment and overseas employment on 173 students majoring in dental technology at two colleges in Daegu metropolitan city and Jeju self-governing island through questionnaires which are recorded individually. The results are as follows. 1. About 31.8% students chose dental technician department taking their aptitude into consideration when they entered college. 52% students gained information about dental technology through internet, and 57.3% students among them, which was the highest level, were under age 20. 2. 48.6% students responded that they thought the level of satisfaction with major was average and there was a difference according to their ages among the level of satisfaction or dissatisfaction with their major and the previous knowledge of major they had gained before entering college. 75.1% students said they wouldn't transfer to other major even if they were given the chance, which was much higher than the opposite case. And only 2.3% students had dissatisfaction at their major, which means students majoring dental technology evaluate their major positively. 3. Most students(58.4%) wanted to get a job for living cost and 53.2% students took advice from their seniors or elderly people in choosing their jobs. 64.7% students answered they should have professional skills to get a good job, which was different according to their ages. In addition, 51.4% students of dental technology department regarded the opportunities to exert their abilities as the most important element in choosing their jobs. That means students value self-decision and selfrealization when they choose their jobs. 4. The majority of students(32.9%) preferred to work at the dental laboratory in dental college hospital as their workplace. Moreover, seniors over age 21 wanted to work in the field of porcelain and juniors under age 20 preferred to work in the implant part concerning the field which students wants to work. 5. About 91.3% students have ever heard about overseas employment and wanted to work abroad if given the opportunities(77.5%). This points out students have much interest in overseas employment and positive attitude. And there was a difference according to age and grade in case of the preferred country when they work abroad 6. The main barrier to overseas employment was a lack of communication ability(63.0%), therefore, students thought foreign language education should be activated to improve overseas employment(26.0%). To show this more specifically, juniors thought foreign language education and internship are most important factors(both are 21.4% alike), while seniors thought foreign language education is essential(24.6%) as a way to improve overseas employment. Students also thought that participation in language study club helps to prepare for overseas employment(69.4%). When putting all these survey results together, it's very important to develop people in advance who have job ability and language ability necessary for overseas employment as well as to improve job awareness in the field of dental technology. Consequently, it's needed to seek for various ways to get a overseas job through foreign language education and overseas internship.

Epimedium koreanum nakai (EKN) has been used for treatment of reproductive disorders. In this study, we evaluated the effects of EKN water extract on the 2-bromopropane (2-BP) induced reproductive dysfunction. The daily sperm production (DSP), sperm counts and histological changes of reproductive organs were investigated after 4 weeks of EKN administration in 2-BP induced reproductive damaged rats. Although the weights of epididymis and seminal vesicle were increased dose-dependently, they were lower than control group. DSP of EKN-dosing groups were increased compared to control group. In EKN-dosing groups, the number of degenerative seminiferous tubules and the number of epididymal tubules showing epithelial cell vacuolation and decreased spermatozoa in the lumen were significantly (p < 0.01) decreased compared to control group dose-dependently. Significant (P < 0.05 or P < 0.01) increases of the number of sertoli cells, spermatogonia, patchytene spermatocytes, round spermatids and elongated spermatids were observed in EKN-dosing groups compared control group. Consequently, based on the results, EKN water extract could treat 2-BP induced reproductive damages dramatically.

This research was performed to develop mass propagation method of Alpine modest primrose (Primula modesta var. hannasanensis T.Yamaz.) for improving the conservation and utilization of the species. Seeds were collected on August 2011 in Jeju-city and well-selected seeds were dry-stored at $4{\pm}1.0^{\circ}C$. Seed size ranged $0.44{\pm}0.07{\times}0.61{\pm}0.04mm$, and weight of 1,000 seeds was $51.78{\pm}0.021mg$. Thus the seed was classified as 'dwarf seeds'. As the result of dormancy characteristics, moisture content of freshly matured seeds increased rapidly by water-soaking treatment and seeds did not germinate at $20^{\circ}C$ for 4 weeks under the light condition. Therefore, seeds were estimated to have physiological dormancy. Germination conditions of dry-stored seeds were found to be $20^{\circ}C$ and light condition, and seeds did not germinated under dark condition regardless of all temperature regimes. Therefore, Alpine modest primrose seed was considered as photoblastic type. Percent germination (PG) and germination energy (GE) were greatly improved by soaking the seeds in $GA_3$ and kinetin for 24 hours. Especially, 200~500 mg/L $GA_3$ treatment resulted in the highest PG (95.5%) and GE (98.3%). So, chemical treatment such as $GA_3$ was thought to be a useful method for raising seedling uniformly.

This paper discusses 5G IOT, Augmented Reality, Cloud Computing, Big Data, Future Autonomous Driving Vehicle technology, and presents 5G utilization of Pyeongchang Winter Olympic Games and Jeju Smart City model. The reason is that 5G is the main artery of the 4th industry.5G is the fourth industrial aorta because 5G is the core infrastructure of the fourth industrial revolution. In order for the AI, autonomous vehicle, VR / AR, and Internet (IoT) era to take off, data must be transmitted several times faster and more securely than before. For example, if you send a stop signal to LTE, which is a communication technology, to a remote autonomous vehicle, it takes a hundredth of a second. It seems to be fairly fast, but if you run at 100km / h, you can not guarantee safety because the car moves 30cm until it stops. 5G is more than 20 gigabits per second (Gbps), about 40 times faster than current LTE. Theoretically, the vehicle can be set up within 1 cm. 5G not only connects 1 million Internet (IoT) devices within a radius of 1 kilometer, but also has a speed delay of less than 0.001 sec. Steve Mollenkov, chief executive officer of Qualcomm, the world's largest maker of smartphones, said, "5G is a key element and innovative technology that will connect the future." With 5G commercialization, there will be an economic effect of 12 trillion dollars in 2035 and 22 million new jobs We can expect to see the effect of creation.

Summary The purpose of this study was to understand the tendency and the meaning of day care center teachers regarding role playing through metaphorical analysis. The data were collected from 166 day care center teachers who participated in A-city university supplement education using the sentence completion metaphorical method. The collected data were categorized and analyzed through a qualitative research method conducted by 2 early childhood education specialists. The results are as follows. First, the tendency of role playing metaphorical expression was divided into 3 categories, 8 contents and the frequency of 'sociality development' was the highest followed by 'emotional development', 'development'. Second, the meaning of role playing metaphorical expression was recognized as 'social skills', 'role experience', 'imitation', and 'understanding of society' in the 'sociality development' category; as 'imagination', 'purification function', and 'means of expression' in the 'emotional development' category; and as 'essential factor of development' in the 'development' category. Based on the research result, it was suggested that the roles of education and teachers for the value and effective operation of role playing in early childhood education institutes should be reconsidered.

The development of a rapidly hardening seal material applicable to steel pipe multistage grouting is described in this paper. In the multistage technique, seal materials are inserted to prevent the backflow of main grouting material. The grouting material must be inserted only after sufficient time has passed for the seal material to reach a gel state. Otherwise, the fluid seal material mixes with the main grouting material and a backflow of the grouting material occurs, thereby making its in situ insertion difficult. Furthermore, if the seal material remains in the gel state for too long a time, it solidifies; and the main grouting material will not be able to seep into the soil. The gel time, i.e., the time needed for the fluid seal material to turn into a gel state, determines the construction period of steel pipe multistage grouting. The gel time is one of the important factors in this technique, because it impacts the total tunnel construction period significantly. This study develops a rapidly hardening calcium aluminate material, which can reduce the gel time and shorten the construction period while retaining proper sealing function. It also presents a method to determine whether the seal material has reached the gel state as well as the quality standard and bleeding rate testing method for the seal material in the gel state.
