Management of Opportunistic Infections after Organ Transplantation
김임경,주만기 대한이식학회 2015 Korean Journal of Transplantation Vol.29 No.1
Solid organ transplantation is a therapeutic option for end-stage organ diseases. However, complications including infection and graft rejection, which are related to immunosuppressive therapy, remain the major causes of morbidity and mortality following solid organ transplantation. The optimal approach to infection in solid organ transplant recipients is prevention; failing this, prompt and aggressive diagnosis and therapy are essential. In addition, the epidemiology of infections after solid organ transplantation has shifted as a result of changes in immunosuppressive strategies and improved survival. Immunosuppression must be linked with appropriate vaccinations, donor and recipient screening, patient education regarding infectious risks and lifestyle, monitoring, and antimicrobial prophylaxis.
Multiple Myeloma Mimics Bone Metastasis From a Rectal Adenocarcinoma
김임경,강정현,김유리,전태주,백승혁,손승국 대한대장항문학회 2017 Annals of Coloproctolgy Vol.33 No.2
A presumptive diagnosis of bone metastasis can be easily made when a patient with a history of colorectal cancer develops bone lesions that are seen on follow-up imaging. In this case report, we describe a patient whose multiple bone lesions were wrongly attributed to a recurrence of rectal cancer rather than being identified as multiple myeloma lesions. When clinicians detect new, abnormal, bony lesions in a patient with a previous history of cancer, they should consider diseases such as multiple myeloma in their differential diagnosis.

This analysis prioritizes export support policies related to establishing an infrastructure for stable production of high-quality strawberries for export. Based on the results, it aims to suggest strawberry export support policies in response to the discontinuation of supporting export logistics costs in 2024. The survey using the AHP method was conducted for 14 strawberry producers and 12 policy consultants(agricultural researchers and rural extension specialists). As a result, the policy directions are prioritized in the following order, from highest to lowest9production of high-quality strawberries(39.9%), establishment of production infrastructure(38.6%), and strengthening of professional competency(21.5%). As for the export support policies are prioritized in the following order9introduction of production guarantee system(13.2%), quality management(13.0%), development of export varieties(11.8%), harvest and distribution facilities(11.0%), food safety control(10.2%), and provision of cultivation facilities(8.3%).

This is a study observe Hospitality & tourism sector targeted at vocational education graduates foster the Curriculum of vocational foster Education courses commissioned components can examine the impact on educational satisfaction. According to the career maturity of student, the population by analyzing the differences between the types of factors that influence satisfaction in the educational career maturity the effect of adjusting the level was empirically verified. This study performed to evaluate for To fulfill this research subject is based in Seoul, the graduates of vocational foster Education courses target a limited and total of 357 valid samples obtained after the SPSS 20.0 and LIMDEP (LIMited DEPendent variable model) 8.0 as the empirical analysis was performed. Related research result, In order to increase the satisfaction level of vocational training of foster job, Candidate foster education and groups will be able to suggest the need for improvement in the provision of factors provides education and curriculum components fit between the characteristics, Target Student of Vocational foster Education courses of Hospitality & Tourism sector research into educational satisfaction and career maturity in terms of graduates can be said to have been the first time a significant progress.

PLS 선형가속기 진공계는 콜라이스트론 첨두출력 54 ㎿, 펄스폭 4.1 ㎲, 반복율 10 ㎐의 마이크로파 전력 공급상태에서 2.6×10^(-6) Pa의 진공도를 유지하고 있으며, 45℃ 운전조건에서 마이크로파 전력이 공급되지 않았을 때 진공도는 2.4×10^(-6) Pa이다. 설치 초기에 30×10^(-11) Torr-l/sec-㎠ 이었던 가스방출율은 각 가속단위마다 약 140 GJ의 마이크로파 에너지가 전파된 현재 1×10^(-12) Torr-l/sec-㎠ 이다. 주 장비로 사용중인 이온펌프는 모두 포화된 상태이며 60 l/s, 120 l/s, 230 l/s 이온펌프의 유효배기속도는 운전 영역에서 각각 45 l/s, 65 l/s, 140 l/s 이다. 진공계 운전중 야기된 문제점들로는 이온펌프 및 진공 게이지 전원제어기의 오동작, 에너지 배가장치의 출력창, 전자총 및 가속관 종단부하의 진공누출 등이었다. 최근 일년간 총 41회에 140.8시간운전 중지를 경험하여 98%의 가용도 (availability)를 나타내었다. 추후 시험중인 도파관 밸브와 개발중인 가속관 종단부하가 설치된다면 가용도를 99.5% 이상으로 증가시킬 수 있을 것으로 기대한다. The vacuum system of PLS linac provides average pressure of 2.6×10^(-6) Pa under high power microwave loading of 54㎿ peak with 4.1 ㎲ pulse width and 10㎐ repetition rates. The base pressure of system is 2.4×10^(-6) Pa with 45°C cooling water. The outgassing rate of the system is decreased from 3×10^(-11) Torr-l/see-㎠ at the initial stage after installation to 1×10^(-12) Torr-l/see-㎠ at present. Total accumulated microwave energy dose is about 140 GJ per module. All ion pumps are working under saturated regime and effective pumping speeds of 60 l/s, 120 l/s, 230 l/s ion pumps are 45 l/s, 65 l/s, 140 l/s under the operating range. Main problems occurred in recent year are troubles of ion pump controller and vacuum gauge controller, vacuum leak of energy doubler window and electron gun ceramic, and water leak in the dummy load of accelerating columns. Total of 41 troubles with 140.8 hours down time give good system availability of 98%. Down time can be reduced by high power waveguide valves and water dummy loads under development, and then availability is expected to be increased up to 99.5%.

본 논문은 포항가속기연구소에서 건설중인 PLS 2 GeV 선형가속기 진공계통의 설계에 관한 것이다. PLS 2 GeV 선형가속기의 진공계통은 길이 3.07m인 42개의 가속관과 길이 약 400m의 도파관으로 구성되어 있다. 진공장치의 배치는 충분한 지역적 배기능력을 고려한 분산 배기방식으로 다지관 방식의 기계적 복잡성을 단순화하였다. 진공계는 가속관 중심과 도파관에서 5×10^(-7)Torr, 클라이스트론 출력창에서 5×10^(-8)Torr까지 배기되도록 설계하였다. 주 진공펌프로는 가속관과 도파관 및 에너지 배가장치에 대하여 각각 용량이 60 l/s와 120 l/s인 sputter 이온펌프를 사용하기로 하였다. This paper describes the vacuum system design for the PLS 2 GeV linac which is now under construction at Pohang Accelerator Laboratory (PAL). The vacuum system of the PLS 2 GeV linac consists of fourty two 3.07 m long accelerating columns and about 400 m long waveguide network. The configuration is adopted by the distributed pumping method to simplify the mechanical complexity from the manifold method. The vacuum system is designed to evacuate the accelerator to the pressure of 5×10^(-7) Torr at the center of the each column and of 5×10^(-8) Torr at the klystron output window. The main pumps are: one 60 l/s sputter ion pump for each accelerating column, two 120 l/s sputter ion pumps for the waveguide system and the energy doubler for each module.
