This paper introduces a modified electro spinning system for biomedical wound-healing applications. The conventional electrospinning process requires a grounded electrode on which highly charged electro spun ultrafine fibers are deposited. Biomedical wound-healing membranes, however, require a very low charge and a low level of remnant solvent on the electrospun membrane, which the conventional process cannot provide. An electrohydrodynamic process complemented with field-controllable electrodes (an auxiliary electrode and guiding electrodes) and an air blowing system was used to produce a membrane, with a considerably reduced charge and low remnant solvent concentration compared to one fabricated using the conventional method. The membrane had a small average pore size (102 nm) and high porosity (85.1%) for prevention of bacterial contamination. In vivo tests on rats showed that these directly electro spun fibrous membranes produced using the modified electro spinning process supported the good healing of skin bums.

There are studied for filmness methods due to disadvantage of conventional X-ray system. Have high DQE, high SNR, amorphous selenium was investigated with image plate. In this point, characteristics of all amorphous selenium image plate was investigated to understand the relationship between the amount of the X-ray exposure and the superficial charge potential in this study. Specially, changes in charge at the surface of the amorphous selenium plate with respect to change of X-ray energy(KeV) was investigated. It was found that the surface charge potential at the amorphous selenium inclosed with respect to the increse in X-ray exposure and that the changed surface potential was a semilinearity in 12.5KeV - 22.5KeV range. Therefore, which suggests that these results call be applied to the development of X-ray image plate.

Medical humanities has become a third area of medical education following basic and clinical medicine. Also, in the national evaluation of medical schools, medical humanities education is an important factor. However, there are many difficulties in teaching medical humanities in medical schools. First, it is still an unfamiliar education area to medical schools and professors. Second, still, there is no consensus on the definition and contents of this education. Third, it is usually very difficult to find professors who have interest and the ability to teach medical humanities. Fourth, even medical students do not understand why they should study medical humanities and sometimes do not eagerly participate in class. This paper suggests some solutions for these problems. First, medical humanities need to be divided into sections according to how easily the contents can be accepted by existing medical education system and apply these sections in the introduction of this education gradually and in stage. One example of the division can be as follows: Group 1) medical ethics and medical law which can be most easily accepted. Group 2) medical communication skills which can be relatively easily accepted. Group 3) medical history and medical professionalism which is relatively difficult to accept, and Group 4) medical philosophy, medicine and music, medicine and literature, medicine and art, medicine and religion, etc. which is the most difficult to accept. In this paper, four things are suggested. Second, divide the contents into mendatory courses and elective courses. Third, allocate the contents throughout the four years from the first year though the fourth year according to the spiral curriculum model. This paper reports some new ideas and methods for medical humanities education. First, to stimulate students' participation, several methods were applied in a large size lecture and student projects. Second, the emphasis of writing in class and evaluation were discussed. Third, the provision of hands on experience is more emphasized than lectures. Fourth, inviting some doctors who work in non-medical areas such as journalism, pharmaceutical industry, etc is suggested. Trial and error is inevitable in this education, but it is essential in molding a good doctor, so medical professors who are interested or in charge of this medical humanities education need to share their ideas and experiences.

This study investigated the feasibility of establishing a college of medicine in the western region of Chungnam to fill the gap in the medical doctor in charge of essential medical care in the region. Currently, the level of medical services in Chungnam is low compared to provinces across the country and in particular, 7 cities and towns, which account for 760,000 people, one-third of Chungnam's population, are located in the western regions of Chungnam. Because of this, in the event of an emergency patients, it is necessary to travel to Cheonan, Daejeon, Seoul, etc. where the regional emergency medical center is located for more than 1 hour and 30 minutes. In the case of critically ill and emergency patients transfer, it is a situation that misses the golden time and causes valuable loss of life. In order to improve the medical environment in the western region of Chungnam and improve the lives of residents in vulnerable areas of medical services, it is believed that establishing a college of medicine in the western region of Chungnam is essential.

Recently, as the clinically positive biological effects of ultra-high dose rate (UHDR) radiation beams have been revealed, interest in flash radiation therapy has increased. Generally, FLASH preclinical experiments are performed using UHDR electron beams generated by linear accelerators. Real-time monitoring of UHDR beams is required to deliver the correct dose to a sample. However, it is difficult to use typical transmission-type ionization chambers for primary beam monitoring because there is no suitable electrometer capable of reading high pulsed currents, and collection efficiency is drastically reduced in pulsed radiation beams with ultra-high doses. In this study, a monitoring method using bremsstrahlung photons generated by irradiation devices and a water phantom was proposed. Charges collected in an ionization chamber located at the back of a water phantom were analyzed using the bremsstrahlung tail on electron depth dose curves obtained using radiochromic films. The dose conversion factor for converting a monitored charge into a delivered dose was determined analytically for the Advanced Markus® chamber and compared with experimentally determined values. It is anticipated that the method proposed in this study can be useful for monitoring sample doses in UHDR electron beam irradiation.

Even now, 119 rescue services have dissatisfactory aspects in operation, system and equipments as discussed above, It is the most urgent subject to systemize rescue services so that they can be suitable for our status, for we will make 21C welfare state come true before long. So, this author suggest that the followings have to be raised to activate 119 rescue service. 1) Bring up experts and offer high-quality rescue service 2) Prepare more up-to-date equipments 3) Operate transfer joint organizations 4) Promote the ability to meet with a press at the time of rescue service activities 5) Adjust regulations related to rescue services 6) Make up for a countermeasure to traffic accidents of ambulances 7) Adjust regulations making it mandatory to establish heliport at the target on hospitals more than a defined scale 8) Install more rescue service teams 9) Educate and train officials belonging to briefing rooms, where the officials with long experiences are arranged 10) Minimize the time for rescue team to reach fields 11) Establish legal protection system for rescue the team Nowadays, our country operates the department of fire fighting and rescue services without great difficulty, even though the circumstances are bad - insufficient members and the inferior circumstances. All of the fire fighting officials are given heavy duties in bad circumstances, and so are the team of rescue service. The rescue service team, taking charge of some emergency medical system, do a fire fighting inspection as a non-duty service, though they are scanty of sleep due to prevention and protection services of the fire fighting service team. But, they can not engage in rescue services completely and have to deal with miscellaneous duties. So they can not offer professional emergency medical services. But now, almost every fire fighting organization, belonging to National Emergency Management Agency, are separating rescue services, which shows a lot of good results. People recognize rescue services to get better and better gradually and the demands for this rescue services increase. So, this is the best time when rescue service teams should offer qualitative services rather than quantitative services. The people will recognize this rescue service team to be an organization sacrificing and serving for them. However well institutes and operation systems should be established, the rescue service team can not come true their aim without strong wills that they will serve and sacrifice themselves for people from their hearts. In addition, it is essential for the officials in charge of policies about emergency medical services to have a concernment on and practice the policy without failure.
