Linux HA 클러스터링을 이용한 모바일 탄소 모니터링 시스템 구현
이재광,김영혁,이재광 한국정보기술학회 2014 한국정보기술학회논문지 Vol. No.
탄소미터링 통합관제 시스템(Carbon-Integration Control System, CICS) 이란 IT 시설물의 에너지 사용현황을 실시간으로 확인하고 제어하는 기능을 가지고 있다. 기존의 CICS는 관제 모듈이 분산, 독립 운영되었으나 SmartRack 기반의 CICS는 항온·항습 센서, 공조기, PDU 등의 장치가 통합되어 전력사용량, 탄소배출량 등의 정보를 수집하고 수집된 정보를 이용해 CICS를 구성할 수 있다. 기존 탄소미터링 시스템은 모바일이 아닌 PC 환경에서 관제 시스템을 제공하지만 본 연구에서는 웹 서버를 추가하여 PC환경에서 통합관제시스템을 제공하는 것뿐만 아니라 모바일에서도 통합관제 할 수 있는 시스템을 제공하도록 구현한다. 그리하여 Linux HA를 적용한 웹 서버를 이용하고 다양한 모바일 기기를 통하여 탄소 관제가 가능한 시스템을 구현한다. Carbon metering integrated control system (Carbon-Integration Metering System, CICS) What is the status of the energy use of IT facilities in real-time has the ability to see and control. CICS based of SmartRack is a constant temperature, humidity sensor based, air conditioners, PDU and other devices are integrated. It is Providing information of Power consumption, carbon emissions, such as. It use configured the CICS. And using the information provided can be constructed of integrated control system. Also, Existing carbon metering system is a Mobile control system, not the PC environment provided. However, in this study, to mobile can be implemented that to provide in the integrated control system by adding Web servers. To safety of web server is applied Linux HA. To deal intelligently in case of emergency. In this paper, Mobile carbon monitoring system implementation using Linux HA clustering on CentOS 5.5 environment.

The purpose of this study was to investigate the effects of one-time participation in liberal arts futsal class on physical strength (1RM squat strength, muscle manual test[quadriceps extension strength: QES, biceps femoris flexion strength: BFS], Side-Step: SS, sargent jump: SJ), heart rate (average heart rate: AHR, maximum heart rate: MHR) and dynamic balance ability (Y-balance test: YBT) in college students. A total of 10 male collage student were divided into control intervention (CON, n=10) and fustal intervention (FSI, n=10) using a randomized crossover design. All subjects were measured physical strength, heart rate and dynamic balance ability before and after a one-time participation in futsal match. QES of the non-dominant side, SS, AHR and MHR showed significant differences between before and after the futsal match in FSI. However 1RM squat strength, BFS, SJ and YBT showed no significant differences between before and after the futsal match in both CON and FSI. It seem that one-time participation in liberal arts futsal class is beneficial for health management.
예방용 췌관 스텐트의 근위부 이탈로 인한 반복성 췌장염

Acute pancreatitis is one of the most common complications of endoscopic retrograde cholangiopancreatography (ERCP). Prophylactic pancreatic stents are effective for reducing the risk for post-ERCP pancreatitis in high-risk patients. However, an unretrieved pancreatic stent, as a result of proximal migration, can cause pancreatitis. We experienced a case of recurrent acute pancreatitis associated with a pancreatic ductal leak and stricture due to proximal migration of a prophylactic stent in a patient with suspected acute gallstone pancreatitis. We endoscopically retrieved the proximally migrated stent and inserted a new pancreatic stent. Follow-up pancreatic imaging showed that the pancreatitis and pancreatic ductal leak/stricture had resolved. ERCP 시행과 연관된 췌장염 발생을 예방하고자, 고위험군에서 췌관 스텐트 삽입이 널리 이용되고 있다. 그러나 췌관 스텐트 삽입 후 췌관의 손상, 스텐트 폐색, 스텐트 이탈 등의 합병증이 발생할 수 있으며, 특히 췌관 스텐트의 근위부 이탈은 췌장염을 일으킬 수 있다. 저자들은 예방용 췌관 스텐트의 근위부 이탈로 인한 급성 재발성 췌장염 환자에서 내시경을 이용하여 스텐트를 회수하고 동반된 췌관 협착과 췌액 누출을 성공적으로 치료한 증례를 경험하였기에 이를 보고한다.

The author reported a case of short-term dynamic psychotherapy in which relatively good therapeutic results were obtained. And I reviewed several therapeutic factors thought to be important in shot-term dynamic psychotherapy from various literatures. In this case, the frequency of session was limited due to her current reality situations. She had suffered from some adjustmental problems and marital conflict before the onset of the illness. The author could grasp the cental theme of her problems early in treatment period and discussed over it including it's influence on current situation and early childhood with th patient. We also discussed about the relationship between the past and current reality so that she could realize her real problem. At the same time, therapeutic effect was enhanced by family therapy and temporary use of medication.
