Objective : Object : A 7-year retrospective clinical and MRI study was reviewed to evaluate the characteristics of pineal cyst. We evaluated results of clinical and radiologic change of pineal cyst during follow up period. Patients and Methods : From 1992 to 1999, 50 patients with pineal cyst were visited for evaluation. Follow up clinical information was obtained from patients or clinical record through phone conversation. also radiologic findi-ngs of pineal cyst in mid-sagittal MRI were reviewed in detail. Results : Pineal cysts were usually asymptomatic and detected incidentally during evaluation of other diseases. Sagittal MRI is the most useful diagnostic test. The radiologic findings of pineal cyst were isointensity on T1WI comared to CSF and slightly high signal intensity on T2WI. Cyst wall was variably enhanced on Gad-enhanced T1WI. The average size of cyst was $13.9{\times}13.0mm$. The pineal cyst was classified into five groups according to previous report. Long term behavior of these lesions are not apparent, but in our study they showed no specific changes in clinical and radiological aspects during 25 months. Conclusion : Although long-term follow up results are needed, the pineal cyst are considered as normal variants. In our 25 months follow up results, there was no rapid change of cyst both clinically and radiologically. Therefore, frequent radiologic evaluation seems unnecessary except type III pineal cyst.

SOAP(Simple Object Access Protocol)은 분산 환경에서의 정보 교환에 사용되는 분산 컴퓨팅 프로토콜로 분산 시스템간에 메시지를 전달하는 방법, 원격 프로시저 호출/응답을 처리하는 방법이 정의하고 있다. 이러한 SOAP은 텍스트 기반의 XML을 이용한 프로토콜이기 때문에 운영체제 및 프로그래밍 언어에 독립적으로 사용할 수 있다. 따라서 전자상거래 표준인 ebXML에서도 메시지 전송을 위해 SOAP을 사용하고 있다. 본 논문에서 SOAP을 기반으로 XML Hub 시스템을 개발하였다. 이에 따라 본 XML Hub 시스템을 기반으로 B2B 메시지 전송이 용이하게 되어, 보다 많은 비즈니스 파트너를 효과적으로 통합관리 할 수 있을 것이다. SOAP is a protocol used for information exchange in distributed computing environment and defines mechanisms for message transferring between distributed system and remote procedure cai]/response process. This SOAP is able to be used independently on operating systems and program languages because it is a protocol using text-based XML. Therefore ebXML that is a standard for I-Commerce adopts SOAP for message exchange. In this paper, we developed XML Hub System based on SOAP By this in Hub System we can more easily exchange messages for B2B. Accordingly we can manage and integrate a lots of business partners.

김용수,박정원,최석호,강준규,Kim, Yong Soo,Park, Jungwon,Choi, Sukho,Kang, Jun-Gyu 한국시뮬레이션학회 2019 한국시뮬레이션학회 논문지 Vol.28 No.4

해수담수화(SWRO, Sea Water Reverse Osmosis) 플랜트는 장기적이고 지속적인 담수 생산을 위하여 설계단계부터 플랜트의 가용도를 고려하여야 하며, 시간의 흐름에 따라 다양한 형태의 노후 현상이 진행되어 시스템 성능의 저하가 발생하므로 가용도 유지를 위한 고장정비 및 예방정비 계획 수립 등이 필요하다. 해수담수화 플랜트와 같이 복잡한 공학구조로 구성된 플랜트 분야에서는 시스템의 신뢰도 혹은 가용도를 수리적인 방법으로 추정하는데 어려움이 있다. 본 연구는 해수담수화 플랜트에 특화된 소프트웨어 개발을 위하여, RAM 분석 프레임워크와 모델링 방법을 개발하고, 가용도 산출을 위한 이산사건 시뮬레이션 모델을 제안한다. 플랜트 정비의 특성을 고려하여 고장 정비 발생 시, 단일 부품의 수리/교체 뿐만 아니라 분해 정비 수준에 따라 접근 가능한 모든 부품을 동시 정비하는 예방정비 정책을 제안하고, 제안된 방법론에 따라 시뮬레이션 모델 및 프로토타입을 개발하였다. 이를 활용하여 국내외에 건설된 해수담수화 플랜트의 현장 데이터를 기반으로 시스템의 가용도 및 가동률 등을 추정 사례 연구를 수행하였고, 그 결과 실제 플랜트의 가용도와 근접한 결과를 얻었다. The Sea Water Reverse Osmosis (SWRO) plant should take into account the availability of the plant from the design stage for long-term and continuous fresh water production. As it occurs, it is necessary to establish a corrective maintenance plan and preventive maintenance plan to maintain availability. In the field of complex engineering structures such as seawater desalination plants, it is difficult to estimate the reliability or availability of the system in a mathematical way. This study develops RAM analysis framework and model, and proposes discrete event simulation model as a application sowtware specialized for seawater desalination plant. Considering the characteristics of the plant maintenance, in case of corrective maintenance, we propose a preventive maintenance policy that not only repairs or replaces a single-broken part, but also simultaneously maintains all accessible parts according to the level of overhaul. A case study was conducted to estimate the availability of the system based on the field data of the seawater desalination plant in Korea and Saudi Arabia. The result was close to the expected availability of the plant.

기후변화와 식품안전에 대한 대국민 설문조사

김용수,Kim, Yong-Soo 한국식품산업협회 2009 좋은식품 Vol.212 No.-

기후변화(Climate change) 문제가 세계적인 초미의 관심사로 대두되고 있다. 특히 기후변화의 주범이 인간활동인 것이 밝혀지면서(IPCC, 2007), 국제사회는 기후변화협약(UNFCCC), 온실가스 배출량 규제 등 21세기 인류가 직면한 최대 위기인 기후변화를 극복을 위한 완화(mitigation)와 적응(adaptation) 전략을 수립하고 시행하기 위하여 총력을 기울이고 있다. 기후변화는 인류와 관련된 모든 분야에 다양하면서 광범위한 영향을 준다. 특히 기후변화로 인한 기온, 습도, 강수량 등의 변동은 식품과 관련된 생물학적, 화학적 및 물리적 위해인자들의 변화를 초래할 것이고, 이는 곧 식품안전 사건과 사고와 직결된다. 우리나라의 기후변화가 이미 국제적 기후변화의 수준을 추월하였고, 향후 급속한 기후변화가 전망됨에 따라(국립기상청, 2009) 기후변화로 인한 식품안전 분야의 적절한 사전예방적 대책 마련이 필요한 상황이다. 이러한 대책의 수립이 시급함에도 불구하고, 기후변화와 식품안전에 대한 과학적으로 증명되어야 할 불확실한 부분이 많이 내재되어 있는 것도 사실이다. 따라서 본고에서는 기후변화로부터 식품안전을 확보하기 위한 제도 정책적 전략 수립에 도움을 주고, 기후변화에 따른 식품안전 분야의 영향에 대한 정보를 국민에게 정확하게 전달할 수 있는 홍보 교육 자료의 개발에 활용할 목적으로 수행된 "기후변화와 식품안전에 대국민 인지도 설문조사" 내용 중 종요한 부분을 발취하여 정리하였다. 이 설문조사는 전국 16대 광역시도에 거주하는 만 13세 이상의 국민을 대상(유효 응답자수 1,036명)으로 "기후변화 인식수준", "식품안전 인식 수준", "식품안전 지식 수준"에 대한 16가지 질문을 전화 면접조사를 통해 설시되었다(표준오차 3.04%, 95% 신뢰수준).

We investigated space establishment and land use of children's parks by studying movement of users in and out of the parks with a questionnaire survey, video and analysis, and then analyzed the characteristics of how the facilities and the space of the parte are used. The results are as follows. First, when considering the character of the facilities of children's parks, entertainment facilities should receive priority followed by those for relaxation and those for convenience. When considering the position of facilities in the parks, because activity spaces may have similar functions to multi-purpose paved spaces, common use of these two spaces should be considered. Entrances and lines of movement should be kept in mind. Second, when considering the surrounding land uses, in case a play facility at a large-sized complex or an elementary school is adjacent, the exercise facilities may be more important, followed by play and rest facilities. In case there is a broad path around the parte, the way in which movement occurs into the central axis should be considered so that the other side of the broad way is not included in the children's play space. Third, proper control of roads adjacent to the parse is needed to protect children from danger.

Background : Early detection and treatment of chronic kidney disease (CKD) are important for inhibition of kidney disease progression and prevention of cardiovascular complications. Treatment of Anemia that is frequently accompanied with CKD, are important for prevention of cardiovascular complications. The lastest K/SOQI-CKD guideline targets early detection and treatment of kidney disease, and the study for these are necessary in Korea. In Korea, until mowadays, the study for prevalence, severity of anemia and influencing factors on anemia in CKD, were rare. Thus in our center, we classified patient for severity of CKD as K/DOQI-CKD guideline and studied prevalence, severity of anemia and influencing factors on anemia. Methods : According to K/DOQI-CKD guideline, patients were staged by GFR calculated by Adbbreviated MDRD Study Equation. Anemia was defined by Hb lessl than 10.0 g/dL below which hemodynamic change develops. We examined the frequency of anemia and independent factors that influences on anemia in study patients. Results : Mean creatinine levels for stage 1 to 5 were 0.87±0.15 (0.7-1.1) mg/dL; 1.04±0.18 (0.8-1.4) mg/dL; 1.69±0.36 (1.1-2.7) mg/dL; 2.90±0.66 (1.9-4.7) mg/dL; 5.01±1.28 (3.3-8.8) mg/dL. Mean Hb levels and percentage of anemic patients in each stages were 12.95±1.46 (10.5-15.4) g/dL, 0%; 13.31±2.20 (7.8-17.7) g/dL, 10.3%; 11.32±2.07 (7.4-16.6) g/dL, 25.5%; 10.10±1.71 (6.7-14.0) g/dL, 54.8%; 9.21±1.53 (6.2-12.2) g/dL, 76.9%. The frequency of anemia were high in Diabeltes Mellitus Mellitus (DM) compared to Non-Diabeltes (Non-DM) at stage 3, 4, 5 [36.7 vs 12.0% (p=0.06); 70.6 vs 35.7% (p=0.000); 100 vs 64.7% (p=0.06)]. Multivariate logistic regression analysis revealed that DM as etiology (OR 2.53, p=0.033 compared with Non-DM), Albumin level (OR of 5.38 p=0.001 for 3.0-1.4 compared with 4.0-5.3 g/dL) were independent factor determing anemia state in addition to K/DOQI guideline stage. GFR, sex, DM, Albumin level were independent factors associated with hemoglobin levels (R^2=0.571, p<0.001). Conclusion : Anemia in CKD was developed relatively early and frequently at stage 3 (Cr, 1.69±0.36 mg/dL, 25.5%) and more aggravated as decreasing renal function (stage 4, 5; 54.8%, 76.9%). DM as underlying disease, hypoalbuminemia were, independently influenced Anemia development.

Purpose : The most common infectious diseases in hemodialysis (HD) patients are sepsis and pneumonia. Although there are many data about sepsis in HD patients, pneumonia in HD patients is rarely reported. This study was conducted to compare clinical severity of pneumonia between HD patients and healthy persons. Methods : This study enrolled 36 HD patients who were admitted for pneumonia. Age- and sex-matched 37 persons with pneumonia who did not have any other medical illness were included as a control. We compared clinical manifestations, laboratory and radiologic findings, complications, and clinical course between HD patients and controls. Results : The positive rates of blood and sputum bacterial culture in the HD patients were higher than in those in the controls (blood; 17.6% vs. 2.7%, p=0.028, sputum; 30.3% vs. 5.4%, p=0.005). Compared to the controls, the HD patients had higher incidence of thrombocytopenia (25.0% vs. 0%, p=0.001) and hypoxia (41.7% vs. 2.7%, p=0.000). The number of the lobes involved was larger and higher incidence of bilateral lesions and parapneumonic effusions were observed in the HD patients. In addition, the HD patients had higher incidence of recurrence than the controls (16.7% vs. 0%, p=0.025). Pneumonia-related mortality rate tended to be higher in the HD patients than the controls but there was no statistical differences between the two groups (11.1% vs. 0%, p=0.054). Conclusion : This study shows that pneumonia in HD patients takes a more severe clinical course than in healthy persons. It seems that pneumonia in HD patients has a higher propensity to develop bacteremia.
