Observation of the current Korean medical education and training system shows that certain negative traits of unchangeable solidification engraft themselves so deeply into the overarching system that they are now hampering the state of the national health welfare. Focusing only on undergraduate medical education, we can point out some glaring side-effects that should be of concern to any stakeholder. For instance, a graduate can legally begin his career as an independent practitioner immediately after passing the licensing exam and return to the old stuck school-year system of 2-year-premedical and 4-year-medical programs where outcome-based and integrated curricula are incomplete and unsatisfactory. In terms of learning opportunities, the balance between patient care and public health, as well as that between in-hospital highly specialized practice and community-based general practice, has worsened. Every stakeholder should be aware of these considerations in order to obtain the insight to forge a new direction. Moreover, our medical schools must prepare our students to take on the global roles of patient care within the Fourth Industrial Revolution, health advocacy for the imminent super-aged society, and education and research in the bio-health industry, by building and applying the concept of academic medicine. We will need to invest more resources, including educational specialists, into the current undergraduate medical education system in order to produce proper outcomes, smart curriculum, innovative methods of teaching and learning, and valid and reliable monitoring and evaluation. The improved quality of undergraduate medical education is the starting point for the success of the national system for public health and medical care as a whole, and therefore its urgency and significance should be emphasized to the public. The medical society should go beyond fixing what is broken and usher in a new era of cooperation and collaboration that invites other health professionals, governmental partners, law-makers, opinion leaders, and the general public in its steps toward the future.

This study was attempted to identify the liquidity trends and determinants of private hospitals in Korea different. Data used in this study were collected from 98 hospitals with complete general data of present conditions as well as financial statements(balance sheets, income statements). They were chosen from hospitals that passed the standardization audit undertaken by the Korean Hospital Association from 1996 to 2000 for the purpose of accrediting training hospitals. The dependent variables in this study were used current ration and quick ratio as a proxy indicator for liquidity. The independent variables were ownership type, hospital type, location, bed size, period of establishment, short-term liabilities to total assets, long-term liabilities to total assets, borrowings to total assets, fixed asset ration, net profit to total assets, operating margin to gross revenue, growth rate of net worth to total assets, total asset turnover, and business risk(volatility of profit). The major findings of this study were as follows. Trends of liquidity(current ratio, quick ratio) had been continuously decreased. Especially, There were very distinct decreasing trends of personal hospitals and less than 300beds, which weakened liquidity. The factors had significant effect on current ratio were short-term debt to total assets(-), fixed asset ratio(-), business risk(+). High short-term debt to total assets, high fixed asset ratio and high business risk significantly decreased in liquidity. The factors that significantly affected on quick ratio were short-term debt to total assets(-), borrowings to total assets(+), fixed asset ratio(-), business risk(+).

The purpose of this study was to investigate food service management system and nutrition education of the early childhood education institute in Yongdungpo, Seoul. Self-administered questionnaires were completed by 26 public early childhood education institute and 34 private ones. A majority of the teachers were women over 40 with at least bachelor's degree. Other than the fact that food service provides food to the children, it contributed in providing the essential nutrients to the children, as well as giving them the opportunity to learn table manners. A normal food service would provide one set of lunch and two sets of snacks, which would be provided by the institute itself. In most cases, the director or teachers planned the menus instead of dietitians. Journals, cookbooks, and other information put out by mass communication, such as TV and newspapers, were used as reference to those menus. The factors considered in planning the menus were mainly nutritional balance and the children's food preference. The difficulties in meal management were about the budget and nutritional menu planning. Fifty five percent of the subjects were did nutrition education, and they focused mainly on the table manners and hygiene education but once a year. The difficulties and complaints in execution nutrition education at the institutes were lack of nutritional knowledge, personal shortage, and excessive work. The institutes were urgently requesting for menu provisions from local Public Health Clinics. As a recommendation from the results of this study, food service management and nutrition related subjects should be more enforced into the nursery teacher training curriculum. Also, it is necessary to provide nutrition education to teachers, and as a link, the need to develop a manual for nutrition education has become urgent.

The purpose of the research is to let people recognize the necessity of Karatedo training and enhance the value of it. Karate sparring is quite helpful to learn the skills that how to escort a protectee as a guard. The skills are divided into hand skills, foot skills and pitching skills. Firstly, it is the hand skills. 'ap-son-chi-gi' or 'di-son-chi-gi' at pressure points such as face, neck and abdomen is effective to overpower adversary. If straight attacks are not easy, 'return stroke' is better. Secondly, it is the foot skills. Front kick towards pressure points, straight attacks like side kick and hindpaw kick and curving attacks like front-spinning kick, 'ap-hu-ri-gi and 'di-hu-ri-gi', these are different types of the foot skills. Lastly, it is the pitching skills. To overpower compeletly, tripping up and 'hu-ri-gi' for breaking the balance and then hand and foot skills for attacking the pressure points are the best way.

Dance movements consist of combinations of movements such as jumping, rotation, maintaining balance, leg lifts, and plantar flexion with toe shoes. Dance movements require great muscle strength of lower extremities as well as muscular endurance. The purposes of this study were to investigate correlation between the anthropometric variables and the peak torque in young female dancers and to identify variables that affect isokinetic peak torque. Twenty-six female dancers ($19.7{\pm}1.2$ years of age) performed concentric maximum force efforts on the knee extensors and flexors at $60^{\circ}/sec$ and $120^{\circ}/sec$, the ankle plantar flexors (PF) and dorsiflexors (DF) at $30^{\circ}/sec$ and $120^{\circ}/sec$. Antropometric variables such as age, height, weight, body mass index (BMI), thigh girth, calf girth and duration of dance training were measured. To identify antropometric variables related to muscle strength, Pearson correlations were computed and a stepwise multiple regression analysis was performed. Pearson correlation coefficients of Knee extensor at $60^{\circ}/sec$ and $120^{\circ}/sec$ revealed moderate positive associations with BMI and thigh girth. Pearson correlation coefficients of ankle PF revealed low-to-moderate positive associations with height. Ankle DF also revealed moderate positive associations with BMI and calf girth. The main predictor variables of knee extensor at 60/sec, were stepwise multiple regression, age, height, thigh and girth.

The optimal identification algorithm of fuzzy systems is presented for rule-based fuzzy modeling of nonlinear complex systems. Nonlinear systems are expressed using the identification of structure such as input variables and fuzzy input subspaces, and parameters of a fuzzy model. In this paper, the rule-based fuzzy modeling implements system structure and parameter identification using the fuzzy inference methods and hybrid structure combined with two types of optimization theories for nonlinear systems. Two types of inference methods of a fuzzy model are the simplified inference and linear inference. The proposed hybrid optimal identification algorithm is carried out using both a genetic algorithm and the improved complex method. Here, a genetic algorithm is utilized for determining initial parameters of membership function of premise fuzzy rules, and the improved complex method which is a powerful auto-tuning algorithm is carried out to obtain fine parameters of membership function. Accordingly, in order to optimize fuzzy model, we use the optimal algorithm with a hybrid type for the identification of premise parameters and standard least square method for the identification of consequence parameters of a fuzzy model. Also, an aggregate performance index with weighting factor is proposed to achieve a balance between performance results of fuzzy model produced for the training and testing data. Two numerical examples are used to evaluate the performance of the proposed model.

The U.S. has recently developed Free and Open Indo-Pacific strategy and Distributed Lethality strategy based on a common perception that they are responding to China's threats. In the future, it is anticipated the following. Strengthen cooperation of the U.S.-India-Vietnam navy, Maximizing the combined combat power between the U.S. and regional navies, Improving its ability to restore damage control, Economic cooperation between the Pacific and Indian countries. The meanings given to the Korean navy are as follows. First, South Korea should pursue cooperation with the Indian Navy, which will grow into a regional balance on China's growth. The growth of the Indian navy is expected to increase cooperation with other Pacific countries. The government should seek ways to promote cooperation with india navy in various fields. Secondly, it is a joint drill between the U.S. Navy and the Korean Navy. Recently, the Korea-U.S. joint drill has not been conducted and many changes are expected to be made regarding the implementation of the joint drill in the future. Therefore, it is necessary to respond to possible changes in the naval relationship between Korea navy and the U.S. navy Also, due to distributed lethality strategy, preparations for operations and training with U.S.navy will be necessary. Lastly, it should contribute to cooperation among regional countries in preparation for maritime territorial disputes. The growth of the Chinese navy and the territorial disputes in the East and South China sea has raised the possibility of accidental military clashes at sea. Therefore, the government should make efforts to create multilateral security cooperation systems that can continue to promote the prevention of armed conflict.

This study aimed to investigate the effect of four common types of Qigong position (standing, sitting, supine, and horse-riding position) on the autonomic nervous system. Thirty healthy subjects participated in this study once a week for four weeks. Electroencephalogram (EEG) was measured three times (before, during, and after the position) while the subject maintained one of four positions for ten minutes. There were significant changes in HRV components compared with EEG power spectra in the standing position. Especially, the ratio of low-to-high frequency (LF/HF) which represents a state of balance of autonomic nervous system was increased. In the sitting position, $\beta$ wave which reflects a state of alert consciousness was increased and both the sympathetic and parasympathetic nerves were activated. On the other hand, in the spine position, $\theta$ wave which signifies a state of relaxation was increased and heart rate (HR) was decreased. Activation of sympathetic and parasympathetic nerves was also observed in this position. Significant increases of indices related to awakening and concentration were observed accompanied by increase of HR and a sympathetic nerve was activated in the riding-horse position. In the present study, it was shown that each Qigong position caused various and significant changes in autonomic nervous system. It would be expected that these results can be applied in the choice of appropriate Qigong position according to objective of Qigong therapy although it is remained to further evaluate the effects of long-term maintenance of Qigong positions and repeated Qigong training.

In injection molding process, the appearance quality issue occurs in most injection molded article. One of thermal designs for the mold was performed by increasing the cavity wall temperature with being as uniform as possible in any position. On the basis of the practical evaluation, the cavity wall temperature and finishing machined cavity surface under the optimum processing conditions are the most significant factors to avoid the appearance issue on the plastic part for a good cosmetic quality. Also, the wrong choice of gate type and location can have a considerable effect on the quality of a molded part and it's so important to keep the correct runner balance from each cavity. We've proposed the education training model of the practical tool technology course for the field oriented education to improve practical tool technology ability and optimized tooling design for injection molding quality which can be performed at the workplace substantially.
