This paper examines the positions and personnel of the Naeui system in the late Joseon Dynasty. First, the regulations of the Naeui system were investigated through the literature related to Naeuiwon. Next, the operation of the regulations, changes in the system, and causes were analyzed through the Seungjeongwon Diary (承政院日記). We discovered: 1) Naeuiwon's medical bureaucracy originally did not have a fixed number of positions, but gradually came into being with a quota regulation. Uiyagdongcham-ui (議藥同參醫) and Naechim-ui (內鍼醫) did not have a quota, but was initially set at 10 people, then expanded to 12 people. Originally, the royal physician had no fixed number, and in 1864 the first quota was 7 people. 2) 'Gyeom-eoui' and 'gachanaeui' served to expand Naeui's quota. After the mid-17th century, 'Gyeom-eoui' expanded the quota of royal physicians to secure a position for the medical bureaucracy of Naeuiwon. 'Gachanae' after King Jeongjo serves to add to the quota while obeying the provisions of the law. 3) The customary promotion of Naeuiwon's medical bureaucracy expanded and became stricter after the mid-19th century, during which special promotions became more frequent than in previous periods. As for the provision of appointment to the 6th class after 30 months, Uiyagdongcham-ui was established in 1686 and Naechim-ui was established in 1718, increasing the chance for customary promotion. In the case of Naeui, the regulation for the Secretary General to raise the degree of official rank has been strengthened since the Cheoljong era. However, special promotions were frequent in the mid-19th century because the number of high-ranking officers increased compared to the previous period. In conclusion, the Naeui system in the late Joseon Dynasty changed in the direction of strengthening their own privileges. The Naeuiwon's quota was increased and promotion was guaranteed through the system and customs. Since the mid-18th century, there have been some regulatory restrictions, but the framework has not changed. This is confirmed not only in the regulations of the documents related to the Naeuiwon, but also in the Seungjeongwon Diary. Naeuiwon's medical bureaucracy enjoyed superiority in promotion and status compared to other forms of technical bureaucracy.

This study is to prepare an evaluation standard about personal information protection and security management of a medical institution and to build up a grade standard of evaluation in PACS environment. We built up evaluation index based on 10 detailed items in four big categories (political security, technical security, data management security and physical security) by referring to ISO17799 (BS 7799), HIPPA (Health Insurance and Portability and Accountability Act of 1996) and domestic medical law. We have investigated at the thirty places where medical facility with the extracted security criteria and security evaluation index. Average score of physical security list, one of the big categories, was 18.5/20 (93%) at all medical institutions. Political security score was 18.5/30 (62%), data management security score was 12/20 (60%) and technical security score was 17.5/30 (58%). Therefore, security evaluation score was average 67 in 30 general hospitals, which was 4th level. The results showed that it is necessary to establish evaluation and management standard about personal information protection and security consciousness which are weak in PACS environment.

This is a preliminary study for developing the method of the dose reconstruction in the patients, irradiated by mega-voltage photon beams from the linear accelerator, using the transit dose distributions. In this study we present the method of three-dimensional dose reconstruction and evaluate the method by computer simulation. To acquire the dose distributions in the patients (or phantoms) we first calculate the differences between the doses at the arbitrary points in the patients and the doses at the corresponding points where the transit doses are measured. Then, we can get the dose in the patients from the measured transit dose and the calculated value of the difference. The dose differences are calculated by applying the inverse square law and using the linear attenuation coefficient. The scatter to primary dose ratios, which are calculated by the Monte Carlo program using the CT data of the patient (or phantoms), are also used in the calculations. For the evaluation of this method we used various kinds of homogeneous and inhomogeneous phantoms and calculated the transit dose distributions with the Monte Carlo program. From the distributions we reconstructed the dose distributions in the phantom. We used mono-energy Photon beam of 1.5MeV and Monte Carlo program EGS4. The comparison between the dose distributions reconstructed using the method and the distributions calculated by the Monte Carlo program was done. They agreed within errors of -4%∼+2%. This method can be used to predict the dose distributions in the patient

Due to the recent economic development and the improvement of income level in China, the desire for quality medical services is increasing compared to the past. As an alternative to satisfy these needs, various applications using smart phones and the like are being developed. The new corona that occurred in December 2019 began to show great interest in non-face-to-face telemedicine services using smart phones due to the worldwide spread of the coronavirus. Therefore, in this study, a total of 200 people were surveyed on the top three mobile medical applications in China, and the data of 120 people who actually used medical applications were analyzed based on Venkatesh's UTAUT2 theory. A study was conducted on the intent to use and the factors affecting the in-law behavior. First, it has become clear that the interactive characteristics, expectations for effort, price value, interest in privacy, habits, and promotional conditions have a positive impact on the user's use. Second, it was investigated that the user's intention to use influences the behavior of use, and among the intentions of use, it was found that the mobilization characteristic expectation, hedonistic motivation, price value, habits, and promotion conditions affect the use behavior. Third, a study result was derived that the controlling variables such as gender, age, school age, and annual income do not affect the user's intention to use mobile medical applications as a controlling variable. Finally, due to the nature of mobile devices that use the Internet, various security vulnerabilities exist, and this can cause great damage or personal and social impact. Therefore, for the development of mobile medical services in China, it is necessary to re-establish a research model through comprehensive and in-depth considerations to supplement these problems in the future.

The technology of AC solenoid valves is now considered as a core technology in the fields of the production line of semi-conductor chips and the micro fluid chips for medical applications. And AC solenoid valves, which operate by compressed air, are characterized by high speed response, great repeatability and that the pressure on the cross sectional area of poppet is kept constant regardless of the fluctuation of the pressure exerted on the ports. In this study, AC solenoid valves that posses the high-speed responsibility and the high rate of flow have designed and analyzed through the law of equivalent magnetic circuit and Finite Element Method (FEM) respectively. In case of poppet, Flow field characteristic was analyzed by the variation of poppet and it was able to display flow field by changing the location of the poppet. Also, we verified possibility of the design through the static and dynamic pressure and the 3D distribution curve of the force by working the front poppet.
