Objectives: The aim of this survey was to investigate utilization, intended use, problems with and demand for medical devices by surveying members of the traditional Korean medical society. Methods: We distributed questionnaires to 13,957 traditional Korean medical doctors via e-mail, and received replies from 1,225. The questionnaire consisted of 4 multiple-choice questions for survey respondent information, 8 multiple-choice questions about the status of medical devices utilizing, and a short answer question about the demand for medical devices. Results: Use of medical devices in traditional Korean medical clinics is common. Diagnostic medical devices are mainly used to assess the patient's condition and to establish a close rapport with clients. In case of therapeutic medical devices, they are usually used for secondary treatment. Issues with traditional Korean medical devices currently in use were ineligibility for national health insurance, low reliability, uncertain validity, and high price. In development of traditional Korean medical equipment, the need for diagnostic medical devices was greater than for therapeutic, and the need for the recording and analysis of medical image data and visualization of medical information was great. Conclusions: There is growing demand for facilitating the development and commercialization of traditional Korean medical devices. To satisfy this demand, research on evaluation indicators that reflect functional and structural clinical information and how to clinically assess the indicators should proceed.

Standard estimates are the numerical data of a unit quantity required for construction work such as the amount of materials, manpower, and the use of equipment required and are also a basis to calculate construction costs. Unfortunately, standard estimates for construction have also been used for garden construction these days as no standard estimates for garden construction have been developed or documented until now. As a result, many problems have arisen at garden construction sites since landscape construction and garden construction differ in terms of scope, size, design and construction methods. The purpose of this study was to develop standard estimates for garden construction for proper calculation of the cost of garden construction and to ensure gardens are created following appropriate construction processes. In order to develop standard estimates for garden construction, a preliminary survey was conducted on experts to understand current issues at first. After that, a questionnaire survey was done to examine problems of construction processes and ways of improvement, and on-site inspections were conducted utilizing CCTVs at construction sites to identify the actual amount of manpower required on site. Based on the results of the surveys and on-site inspections, a draft version of standard estimates for 5 types of planting work for garden construction was developed. Developing standard estimates for garden construction will serve as a stepping stone for the transparent and proper compensation for garden construction work, which will not only contribute to addressing issues between consumers and construction companies, but also to the stabilization of market economy and job creation.

목적 : 환자의 치료에 있어서 정확한 장비의 설치와 성능 평가는 치료의 질을 향상시키는데 중요한 요소라고 할 수 있으며 사용자가 장비의 특성과 사용 방법을 숙달하고 업무를 수행하는 것이 매우 중요하다고 생각한다. 그러므로 방사선 치료기를 설치하고 방사선 치료를 하기 전에 사용자가 직접 장비의 설치와 성능 평가에 참여하고 특성을 파악하여 이해하는 것이 필요하다. 본 연구에서는 CAP의 과정과 성능 평가결과를 소개하고자 한다. 대상 및 방법 : 선형가속기 21EX(varian, USA)를 대상으로 설치 시부터 성능 검사까지 전 과정을 평가하였고 성능평가는 크게 radiation survey, mechanical test, radiation isocenter test, beam performance, dosimetry, enhanced dynamic wedge로 구분하여 X-omat film(kodark), 선량 측정 장비(multidata, densitometer, electrometa)를 이용하여 실시하였다. 또한 선형가속기에 부착된 MLC(millenium, 120leaf)와 EPID(portal vision)의 성능 평가는 별도로 실시하였다. 결과 : Survey meter를 이용하여 측정한 leakage는 허용 범위 이하의 선량이 검출되었고 mechanical test에서 collimator, gantey, couch rotation은 1mm 이하였고 육안으로 평가한 angle은 digital이 ${\pm}1^{\circ}$이내에 mechanical은 ${\pm}5^{\circ}$이내였다. 또한 light field와 cross-hair의 직선성 검사도 1mm이내로 평가되었다. (A)symmetrical jaw field는 upper/lower 모두 ${\pm}0.5mm$이내였다. X-omat film을 이용한 radiation isocenter test는 1mm 이하였고 light field와 radiation field 의 일치성 검사는 ${\pm}1mm$ 이내였으며 선량 측정 장비를 이용하여 측정한 $\%DD$는 photon energy는 모두 ${\pm}1\%$ 이내로 electron energy는 $90\%,\;80\%,\;50\%,\;30\%$를 측정한 결과 허용 범위 내에서 평가되었다. photon 과 electron energy의 flateness는 각각 $2.3\%$(기준 $3\%$)이내, $3\%$(기준 $4.5\%$)이내이고 symmetry는 $0.45\%$(기준 $2\%$), $0.3\%$(기준 $2\%$)이내에서 평가 할 수 있었다. 그리고 dosimetry test는 sort term, MU setting, rep rate, dose rate accuracy를 photon과 electron energy 별로 MU와 gantry angle을 바꿔가면서 측정한 결과 허용범위 오차이내에 포함되는 것을 확인 할 수 있었다. EPID(portal vision)의 Exact-Arm의 기계적인 검사는 vertical, lateral, longitudinal은 허용범위 내에서 동작했으며 명암과 해상도 검사도 05.mm의 니크롬선이 선명하게 나타났으며 phantom의 음영도 뚜렷하게 나타났다. Multileaf collimator(MLC)검사는 leaf이 isocenter의 중심에 정확하게 배열되었으며 재현성 검사도 정상적으로 동작하였다. 결론 : Clinac 21EX 장치의 customer acceptance를 통해서 향후의 환자의 치료를 하는데 있어 장치의 안정성을 확인 할 수 있었으며 치료 전의 선형가속기와 주변장치의 특성을 파악 할 수 있어서 장비 사용에 있어서 어려움을 감소시킬 수 있으리라고 생각된다. 또한 사용자가 적극적으로 참여함으로써 앞으로 환자를 치료하는데 있어서도 많은 도움이 되리라 생각한다.

Objective : Cerebrovascular disease (CVD) was the third most common cause of death in South Korea in 2014. Evidence from abroad suggests that comprehensive stroke centers play an important role in improving the mortality rate of stroke. However, surgical treatment for CVD is currently slightly neglected by national policy, and there is still regional imbalance in this regard. For this reason, we conducted a survey on the necessity of, and the requirements for, establishing regional comprehensive cerebrovascular surgery centers (CCVSCs). Methods : This investigation was performed using the questionnaire survey method. The questionnaire was consisted with two sections. The first concerned the respondent's opinion regarding the current status of demand and the regional imbalance of cerebrovascular surgery in South Korea. The second section asked about the requirements for establishing regional CCVSCs. We sent the questionnaire to 100 board members of the Korean Society of Cerebrovascular Surgeons. Results : Most experts agreed that cerebrovascular surgery patients were concentrated in large hospitals in the capital area, and 83.6% of respondents agreed that it was necessary to alleviate the regional imbalance of cerebrovascular surgery. With regards to personnel, over 90% of respondents answered that at least two neuro-vascular surgeons and two neuro-interventionists are necessary to establish a CCVSC. Regarding facilities, almost all respondents stated that each CCVSC would require a neuro-intensive care unit and hybrid operating room. The survey asked the respondents about 13 specific neurovascular surgical procedures and whether they were necessary for a regional CCVSC. In the questions about the necessity of cerebrovascular surgical equipment, all seven pieces of equipment were considered essential by all respondents. A further five pieces of equipment were considered necessary on site: computed tomographic angiography, magnetic resonance angiography, conventional angiography, surgical microscope, and surgical navigation. Our results may provide a basis for future policy regarding treatment of cerebrovascular disease, including surgery. Conclusion : Raising the comprehensiveness of treatment at a regional level would lower the national disease burden. Policies should be drafted regarding comprehensive treatment including surgery for cerebrovascular disease, and related support plans should be implemented.

This study was aimed to investigate factors that affected the status of wearing personal protective equipment (PPE) for handling poultry carcasses with potential exposure to virulent avian infectious agents. A large outbreak of high pathogenic avian influenza (HPAI) occurred in South Korea in 2014. Many public officers participated for euthanizing and handling livestock carcass. However, several safety issues with using PPE were revealed. Therefore, a questionnaire survey was conducted for 340 people who participated euthanasia and carcass disposal in the place where HPAI mainly occurred in 2014. It was found that 31.8% of the respondents had ever taken off their protective equipment during operations because of its inconvenience. The most inconvenient PPE was goggles (54.6%), followed by mask (20.2%), latex gloves (11.6%), shoe covers (5.9%) and protective clothing (5.3%). The main complaints about this individual PPE was unclear sight, damp emitted toward eye, sweating, tearing easily and sweating, respectively. Considering such problems of PPE, new possible directions for improvement of gloves and goggles were suggested. With newly developed rubber coating fabric gloves and conventionally using latex and fabric gloves, H3N2 influenza virus transmission experiment was conducted. Rubber coating fabric gloves showed similar efficiency for blocking virus transmission with latex laboratory gloves and were not easily torn by sharp claws of chicken. In addition, air flow control safety eyewear was suggested to minimize moisture formation. The air flow control system efficiently suppressed moisture formation inside the goggles. Therefore our study will provide more specific directions about new PPE development for safety protection of actual wearers.
