Purposes: The purpose of this study is to argue that the taxation system for non-for-profit medical institution in Korea should be revised and that the basic direction should be to expand tax exemption like the US. Methods: We analyzed the US context of taxation policy for non-for-profit medical institutions and compared the US and Korean situation. Findings: In the United States, for-profit or non-for-profit medical institutions eternities are the most important criteria for hospital classification. Basically, full tax-exemption has been applied for non-for-profit medical institutions. The reason why many hospitals maintain their status as non-for-profit are following. First, the American society places great importance on the social responsibility and role of non-for-profit hospitals. Second, maintaining the status of non-for profit medical institutions is financially beneficial while maintaining good social reputation. The most powerful financial incentives are tax deductions and tax deductions for donations. Practical Implications: How will the taxation system for medical institutions in Korea be reformed in the future? First, if Korean government do not allow for-profit medical institutions, Korean government should consider implementing a full tax exemption system suitable for non-profit medical institutions like the US. Second, there are many variation in taxation for non-for-profit medical institution according to their legal positions. Therefore, current taxation system should be revised. Third, the reorganization of such taxation system should be in a direction that can finally encourage community benefit activities of medical institutions of nonprofit hospitals.

Objectives : The purpose of this research was to develop the magnetic acupuncture system which used solenoid coil for magnetizing acupuncture needle. The system could generate the meridian electric potential (MEP) similar to the potential by manual acupuncture. Thus, we tried to confirm the therapeutic effect that is caused by the MEP generation. Methods : To confirm the MEP, we stimulated the magnetic acupuncture with at 2Hz, $92.7{\pm}2mT$, PEMFs (Pulsed Electro-Magnetic Fields) at ST37 and measured the evoked potential between ST36 and ST41. Also, we conducted a fatigue recovery test using isokinetic exercise in order to identify the therapeutic effect on musculoskeletal disorders. We chose LR9 as a stimulation point. To observe the state of fatigue, we measured the EMG and analyzed median frequency and peak torque for 20minutes. Results : We observed that MEP which incurred from magnetic acupuncture was higher than he reported MEP induced by manual acupuncture. Moreover, its modes were divided into two types by the direction of magnetic flux. When generating magnetic flux in the direction of acupoint, the positive peak voltage of the MEP was generated. In contrast, negative peak voltage of the MEP was generated whenever meganetic flux generated in the outward direction. As a result of fatigue recovery, the median frequency (MF) of the magnetic acupuncture group were recovered faster than that of the non-stimulation group. However, the peak torques of both groups were not restored until after 20 minutes. Conclusions : We confirmed that the magnetic acupuncture system can lead to the MEP similar to manual acupuncture. Moreover, the MEP had a therapeutic effect on the musculoskeletal disorders.

This study aims to analyze the characteristics of the management situation of the Korea Railroad Corporation(KORAIL) through the management innovation process of the KORAIL and to suggest its implications for military application. Despite stable demand, the railway passenger industry had the limitation of not being able to abolish deficit routes due to public service obligations. In addition, the launch of the Suseo High-Speed Line has introduced a competitive system, posing a threat to corporate management. KORAIL wanted to overcome this crisis by innovating its management through the utilization of big data, improvement of the freight business, decentralization of demand, the introduction of tourism railroads, and development of station influence areas. By utilizing big data, KORAIL was able to optimize the railway fare system while reducing fixed costs spent on railway maintenance. It also drastically reduced the station of cargo and created a base station to pursue economies of scale. On the other hand, the existing exclusive station system was abolished to solve the chronic saturation of the downtown area, and the railway demand was moved to Gwangmyeong Station and Suwon Station to optimize the passenger supply. In particular, it developed a new business model called the tourism railway by developing the mountain Byeokjin Line, which was a chronic deficit line, and sought to improve liquidity through the development of the station influence area. Such a process of innovation at KORAIL suggests an appropriate direction in seeking ways to innovate the military medical institutions. First of all, the necessity of improving organizational immersion through the development of a personnel structure suitable for the compulsory organization, while expanding the facilities of the division and corps, and reducing the time required for medical treatment and waiting through the establishment of a data-based medical system was suggested. Next, it was also discussed to integrate the National Health Medical College, which received accreditation as a medical facility through the designation of advanced general hospitals and is ultimately under discussion with the Medical Institution. Through this, we hope that the military medical institutions, which are facing various challenges, will overcome existing limitations and be re-lighted as innovative institution that provides comprehensive public health services.

Objectives : This study aims to diachronically examine the classification systems of all materia medica, followed by categorization and analysis of each category to deduce each category's characteristic. This will provide foundation for further examining classifications of bencao in contemporary herbology. Methods : Classification systems from a total of 93 bencao related texts were collected and categorized. Each category's classification system was analyzed to determine its meaning. The classification systems were compared from a diachronic perspective, to further deduce each system's problem from a historical context. Results : The classification systems of materia medica could be summarized as following three standards: quality, origin, and medical application. In reality, bencao could be generally classified according to origin and medical application. The origin-based classification system provided a stable and flexible classification outline in the expansion process of bencao. The medical application-based classification strengthened the relationship between bencao and illness pattern, improving clinical applicability. Conclusions : In the history of herbology, the two classification systems created the current of herbology through mutual contribution and conflict. We hope that further discussion on the direction towards which classification system of bencao in contemporary herbology should head will proceed based on this study.

본 연구의 목적은 토모테라피(Hi-ArtII, TomoTherapy, USA) 치료 시 Bodyfix system (Medical Intelligence, Ele-kta, Schwabmuchen, Germany)에서 진공압박(Vacuum compression)에 따라 환자 위치잡이오차(Patient's setup-errors)를 평가하고자 하였다. Bodyfix system와 진공압박을 적용한 토모테라피를 이용하여 치료를 시행한 흉복부 환자 21명을 선정하였으며, 모든 환자는 치료 전 촬영된 총 477개의 메가볼테이지 전산화단층촬영(Mega-voltage computed tomography, MVCT)영상을 얻었다. 이를 통하여 확인된 좌우방향(Medial-Lateral direction, ML), 앞뒤방향(Anterior-Posterior direction, AP), 상하방향(Superior-Inferior direction, SI)과 SI중심축 회전각(Rotational angle of SI axis direction, Roll)에 대한 오차를 기록하고, 분석하였다. 세 방향 및 Roll에 대한 상관관계와 진공압박 정도가 다르게 적용된 다섯 그룹에 대하여 setup-errors를 분석하기 위해 각각 Pearson's product-moment coefficient와 One-way ANOVA를 이용하여 통계적으로 분석하였다(p<0.05). 분석결과 Systematic errors의 평균은 AP에서 6.00 mm, 표준편차는 SI에서 5.95 mm로 큰 오차를 보였다. Random errors의 평균은 SI방향에서 4.72 mm로 큰 오차가 발생하였다. 관계분석에서는 상관계수가 ML-Roll과 AP-Vector는 0.485, 0.244이고, SI-Vector에서 관계가 제일 높았다(0.637). 또한, 진공압박 정도가 다르게 적용된 다섯 그룹(Pressure range: 30~70 mbar) 사이의 setup errors를 분석한 결과 ML, SI방향과 Roll에서 모두 p=0.00 (p<0.05)로써 유의한 차이를 보였으며, SI방향에서 진공압박에 따른 오차 평균은 40 mbar과 70 mbar그룹에서 4.78 mm, -0.74 mm였다. 본 연구에서는 진공압박과 setup-errors의 평가를 통계적으로 분석하였으며, 압박 정도에 따라 SI방향에서 setup-errors의 차이를 확인하였다. 최종적으로 setup-errors와 내부장기의 움직임을 고려하자면 Bodyfix system을 이용한 진공압박을 적용시 최소 50 mbar 이상을 사용해야 할 것이다. 본 연구결과를 토대로 진공압박의 정확성과 내부장기 및 종양의 움직임을 정량적으로 분석할 필요가 있다고 판단된다.
