This study is aimed at exploring the direction and characteristics of Japanese medical facility improvement in each area, a move to strengthen local medical services. Also, this study is intended to establish implications for Korea, which has similar social conditions as Japan's. Based on the findings, Japanese medical facility improvement has the following characteristics. First, as for medical service supply system, the linkage between facilities was being strengthened. The purpose is to share the functions and roles of limited medical facilities. It allows patients to receive complete medical services in one area. Second, local public health facilities were consolidated to boost their management efficiency and to improvement their original functions. Third, local medical facility roles were divided into different levels. The purpose is to treat patients more efficiently depending on their diseases. In other words, the cooperative medical system was strengthened by dividing the roles of medical facilities. It is aimed at treating each patient more systematically depending on their conditions in line with the treatment stage. The findings suggest the following for Korea. In order to supply and maintain stable medical services regionally in line with social changes, functional issues of medical facilities should be tackled consistently and systematically.

Purpose: This study aimed to investigate the awareness and direction of paramedics work and image in hospitals. Methods: From April 16 to May 5, 2015, data were collected through structured questionnaires from 45 paramedics and 81 nurses working in emergency medical institutions. The data were analyzed using SPSS version 18.0. Results: The work of paramedics is evaluated to be highly worthy at the in-hospital level rather than at the injury first-aid treatment level. It appears that paramedics are often forced to do what their hospitals tell them to do concerning matters related to conflicts with them and nurses. Paramedics stated that they experienced greater mental stress than those engaging in other professions, a finding similar to those of other studies. There was no statistically significant difference in opinions between the two groups about a desirable direction for the development of first-aid services at hospitals. More than two thirds of the respondents said that paramedics should be given the right to enter acting check for patients. Conclusion: Paramedics work is shown to differ in the opinions of paramedics themselves and nurses. Paramedics need for reform is associated with expanding the work of the law.

Since it was found out that the degree of medical contribution to health was timid. the direction of health policy studies has been focused on the personal health behavior. Participation in health has been closely related to the behavior. Those who have insisted on the new direction believe that the health policy laying stress on low cost and personal responsibility can avoid the pathology of medical policy and medical crisis. Participation in health has been very important method of changing health behaviors. It is certainly important to change bad health behaviors. But there is no deliberation of social structure here. Most health behaviors are the adaptation to social structure. The attempt to change the established adaptation behaviors without considering social structure is difficult to succeed. It is little meaningful to say the importance of the health behavior to those who have no choice but to be ill due to the poor environment and health risks. What can guarantee the real direction of community participation at least is the consciousness and behaviors of people's right.

Objective: The purpose of this study was to investigate the effects of resistance applied in various directions on lower extremity muscle activity and balance during squat exercise performance. Design: Cross-sectional study. Methods: Forty-one adults (19 males and 22 females) agreed to the study purpose and procedures. All subjects randomly performed squat exercises with an intensity of overcoming 10% of body weight resistance pulled forward, backward and general squats with $60^{\circ}$ of knee joint flexion. Electromyography was used to measure muscle activity of the vastus medialis oblique (VMO), rectus femoris (RF), vastus lateralis oblique (VLO), biceps femoris (BF), and semitendinosus (ST) muscles. The Wii Balance Board was used to assess balance during the three-method squat operation. Each operation was measured three times for 10 seconds. Results: There were significant differences in muscle activities of the VMO, RF, VLO, ST and balance ability with the application of three directions of resistance (p<0.05). Post hoc comparisons revealed that squats performed with resistance pulled in the backward direction resulted in higher VMO, RF and VLO activity than with the resistance placed in a pulled forward direction (p<0.05). In the ST, resistance applied in the pulled forward direction showed greater muscle activity compared to the pulled backward direction (p<0.05). With balance, squats performed with resistance pulled in the forward direction showed greater muscle activity than with resistance applied in the pulled backward direction and during general squat performance (p<0.05). Conclusions: In this study, squat exercises performed with resistance applied in the direction of pulling backwards was found to be the most effective in improving quadriceps muscle strength and balance. It is effective to provide resistance that is placed in the forward when it is difficult to perform a general squat due to weakness of the quadriceps.

The aim of this study was to reveal correlation between scope of practice and clinical paramedic properties. from April 9 to May 12, 2012, one hundred and eighty-one clinical paramedics filled out anonymously to the questionnaire which includes gender, academic background, clinical career, clinical practice and medical direction. To analyse the collected data, Pearson's r at ${\alpha}$=0.05 (two-tailed) was performed using IBM SPSS 19 (Chicago, IL, USA). One hundred and forty (77.4%) working at medical facilities, one hundred and four (57.5%) graduated from four-year colleges, seventy seven (42.5%) acquired paramedic certificate in 2010-2012, one hundred and twelve (61.9%) charted on nursing records, one hundred and sixteen (69.6%) had a good knowledge in scope of practice, one hundred and six (58.5%) thought of legal restriction & absence of direct medical direction leading to narrow clinical practice. Implementing practices and practices needed were thirty two. There were significant relationships in Likert scale 1-5 between paramedic competency and legal practice (p=0.039); implementing practice (p=0.006); practice needed (p=0.049); and overall (p=0.001). Also, between knowledge on scope of practice and implementing practice (p=0.003); overall (p=0.047); clinical career and legal practice (p=0.019); practice needed (p=0.002); and overall (p=0.002). However, these correlations were relatively low (r $$\leq_-$$ 0.238). The working condition of clinical paramedics was restricted by the Emergency Medical Services Systems Act, which requires a narrow scope of practice. This condition leads to the poor quality of emergency care, therefore the scope of practice in the act will be revised from specificism to generalism, from direct medical direction to indirect medical direction by means of quality management.

As the Minimally Invasive Surgery (MIS) is developed, an interventional procedure becomes the major of the spine surgery in the world. Despite of the use of the expensive medical equipments, the success chance of the nucleoplasty is about 30%. The reason is that the shape of the cannular needle is similar to that of the conventional injector and looks like the straight. Because the tip of these straight needles is not able to reach in the vicinity of the disc bulging or the protrusion, which are the cause of the low back pain and because the far indirect plasma discharge results in the decompression, the nucleoplasty has the limit. Many incurable diseases has not been solved due to the unexistence of the advanced technique for the MIS human body cannula device. If 3-D direction controllable cannular catheter (whose direction is accurately controlled after inserting into the bodies to cure the lesion) is developed, it is expected that new devised cannular catheter can cure many incurable diseases simultaneously. Therefore, the aims of this research are to develop the new devised cannular catheter of SMA direction controller for the medical situation, which has been produced through many previous trial-error procedures, and to produce the commercial medical device.

In this paper, we analysis 3 types of magnetic resonance image for determining whether brain infarction period is hyperacute or not. If its peirod is hyperacute, we can predict brain infarction transition direction. We use EPI(Echo Planar Image) for prediction of brain infarction transition direction. EPI is a good image for detecting brain infarction because EPI can detect the moving of water in brain which play an important role in deciding method of medical treatment. We utilize characteristics of 3 type of MRI and their relation in brain infarction patient for determining brain infarction period. By this method, we obtain each period characteristics and predict brain infarction transition direction more accurately comparing past method.
