During the previous few years, local universities have experienced a rapid decrease in registration of new student for admission because of the problem of excessive concentration to Seoul metropolitan area and decrease in the number of population under school ages. Even though they are tring to survive from the difficulties by developing new strategies to increase the number of new students, it has no meaning if there is no standpoint of marketing. So, this study suggests that introduction of demander focused marketing concept actively is needed breaking the general and conservative method when the university devise entrance examination strategy. Also, using of positioning map is suggested and the examples are showed as finding differentiation factors with competitive university.

Grain boundary diffusion plays a significant role in fission gas release, which is one of the crucial processes dominating nuclear fuel performance. Gaseous fission produce such as Xe and Kr generated during nuclear fission have to diffuse in the grain lattice and the boundary inside fuel pellets before they reach the open spaces in a fuel rod. These processes can be studied by 'tracer diffusion' techniques, by which grain boundary diffusivity can be estimated and directly used for low burn-up fission gas release analysis. However, only a few models accounting for the both processes are available and mostly handle them numerically due to mathematical complexity. Also the numerical solution has limitations in a practical use. In this paper, an approximate analytical solution in case of stationary grain boundary in a polycrystalline solid is developed for the tracer diffusion techniques. This closed-form solution is compared to available exact and numerical solutions and it turns out that it makes computation not only greatly easier but also more accurate than previous models. It can be applied to theoretical modelings for low bum-up fission gas release phenomena and experimental analyses as well, especially for PIE (post irradiation examination).

Laryngostroboscopy is one of the most practical techniques for clinical examination of the larynx. The videostroboscopy provides valuable information concerning the nature of vocal folds' vibration, an immediate image of the presence or absence of pathology, and a permanent record. Additionally, when used by trained observers in conjunction with other instrumentation, it can provide both qualitative and quantitative data on vocal function of both the normal and disordered larynx. The authors examined the 388 patients with voice disorders by videostroboscope. This paper describes the clinical procedure of laryngostroboscopy based on some introductory remarks on laryngeal anatomy and function. And the findings of parameters observed by the stroboscopy is noted for the laryngeal disorders.

This study was carried out to investigate the characteristics survey of Clavicorona pyxidata strains. C. pyxidata are selected 3 kinds of strains collected in GWANG DEOCK Mt., DO BONG Mt., and BUK HAN Mt., Mycelial growth of C. pyxidata collected from GWANG DEOCK and BUK HAN Mt. is 64mm, 60mm for 18days respectively. DO BONG Mt strain is 85mm for 9 days. Transparent crystal body of C. pyxidata mycelia were appeared by microscopic examination of 100 magnification. Optimal temperature of mycelial growth in C. pyxidata strains are 25~30℃ respectively.

Whole body vibration is a new type of exercise that induces the response and adaptation of the neuromuscular system by stimulating tendons or muscles through vibration of various frequencies and muscle strength on the footrest. Therefore, in this study, we tried to find out the effect of health promotion and physical fitness promotion on agility, flexibility, and quick reaction ability in the state of general paralysis. Body vibration exercise was additionally applied to the entrance examination practical program for students preparing for the physical education entrance exam.

Religions and beliefs can affect the shopping behaviors of its followers and practitioners. However, the knowledge about the factors that motivate, facilitate and even constrain customers' purchase of spiritual goods, such as feng shui items, is limited. Therefore, in this study, I examined the reasons, facilitators, and constraints of purchasing spiritual goods from the buyers' perspective. Two research questions directed the examination process, including (1) why users buy spiritual goods? And (2) what factors may facilitate or constrain the purchase and use of spiritual goods? Using Vietnam's feng shui market as the context, I applied the autoethnographic and ethnographic methods to collect and analyze the data. I found that the two main reasons to purchase the feng shui items were the products' meaning and beauty. In addition, I observed three groups of factors that could facilitate or constrain the purchase and use of feng shui items, including information about the products and their sellers, disposable income and life stage of the buyers, and price and authenticity of the products. Finally, based on these findings, I discussed the practical implications for managing the spiritual goods market in Vietnam.

In this paper, our primary focus revolves around the examination of a set of fractional stochastic models. Through our investigation, we can establish the presence of a solution and its distinctiveness. Additionally, we employ a moment-based algorithm to estimate the coefficients within these models and provide evidence that these estimations maintain their asymptotic characteristics. To support this claim, we conduct experimental studies using simulations and numerical examples.

Purpose: The purposes of this research were to study the validity of the National Examination based on smart based test(SBT) by 7 types of healthcare occupation. Methods: We conducted a questionnaires survey among 1,219 people including 210 professors for all 7 types of healthcare occupation and 573 clinical specialists ; 436 students from random sampling participated and the reliability of the questionnaire was tested using Cronbach's alpha. Results: Professors from 7 types of healthcare occupation were investigated for their opinions on the introduction of the SBT system ; 65.9% of the professors answered positively on the introduction of the SBT National Examination System, while 40.1% of the clinical experts answered likewise. In particular, professors and the clinical experts recognized altogether that the multimedia questionnaire, being effective for the evaluation of clinical and practical competence of the subjects, enabling the evaluation of various areas and strengthening the school education in clinical practices, the 42.0% of the students from 7 departments answered that the future direction of the national test is in the SBT test system with significant difference (p=.000) found in students majoring in order of Emergency Medical Services, Radiology and Physical therapy, compared to students from other majors, showing the positive response to the SBT system. Conclusion: The results of this study comprehensively evaluated the positive recognition of development of multimedia items and SBT system in national examination of 7 types of healthcare occupation in professors, field specialists and students.

Background: There are practical difficulties to show exact clinical symptoms such as seizure to medical students at Clinical Performance Examination (CPX). We developed a new CPX case of child's seizure on video using smartphone. Methods: A total of 356 $4^{th}-year$ students of five universities in Daegue-Gyeongbuk and Gyeongnam area took the clinical skill examination from June $13^{th}$ to $17^{th}$ in 2016. Among them, 72 students took the new CPX case in June $15^{th}$ and 71 students filled out the questionnaire on whether the new CPX with smartphone video is helpful, authentic, difficult, and necessary for other CPX. All the questions were measured on 5-Likert scale. Results: Mean score of the new CPX was 57.1, lower than the mean scores of the other 11 CPX cases, 62.8. For the question "Smartphone videos helped to solve the problem", 45 students (63.4%) answered 'Very much'. For the question "Is it realistic compared to other questions?" 30 students (42.3%) and 25 students (35.2%) answered 'Very much' and 'Much'. For the question "Is it difficult compared with other questions?" 18 students (25.4%) and 26 students (36.6%) answered 'Very much' and 'Much'. As for the question "I would like to have more tests using smartphone video", 26 students (36.6%) answered 'So and so'. Conclusion: A majority of students responded that video presentation was helpful and authentic to figure out the CPX, whereas they assessed smartphone video was more difficult compared with other CPXs. Further, students were negative toward using smartphone video for the other CPXs.
