Infectious disease emergency hospitals are usually temporarily built during the pneumonia epidemic with higher requirements regarding diagnosis and treatment efficiency, hygiene and safety, and infection control.This study aims to identify how the Building Information Modeling (BIM) + Industrialized Building System (IBS) approach could rapidly deliver an infectious disease hospital and develop site epidemic spreading algorithms. Coronavirus-19 pneumonia construction site spreading algorithm model mind map and block diagram of the construction site epidemic spreading algorithm model were developed. BIM+IBS approach could maximize the repetition of reinforced components and reduce the number of particular components. Huoshenshan Hospital adopted IBS and BIM in the construction, which reduced the workload of on-site operations and avoided later rectification. BIM+IBS integrated information on building materials, building planning, building participants, and construction machinery, and realized construction visualization control and parametric design. The delivery of Huoshenshan Hospital was during the most critical period of the Coronavirus-19 pneumonia epidemic. The development of a construction site epidemic spreading algorithm provided theoretical and numerical support for prevention. The agent-based analysis on hospital evacuation observed "arched" congestion formed at the evacuation exit, indicating behavioral blindness caused by fear in emergencies.

본 논문에서는 사이버물리시스템에 대한 사이버공격 경호위협 중 지능형건물관리시스템(IBS)을 중심으로 발생할 수 있는 사이버공격의 특성과 주요 위협 시나리오를 분석했다. 분석한 결과 일반적으로 예측이 가능한 위협에 대해 공격의 성공 가능성을 낮추는 것이 현실적인 공격의 대응방법이 되는 것으로 판단하였고, 구체적인 대응방안으로는 다계층 방어시스템의 적용과 보호대상 시스템에 대한 사이버안전진단 사전점검, 이동식 보안관제 시스템과 같은 방안들을 제시하였다.

BiSrCaCuO superconducting thin films have been fabricated by co-deposition using IBS(ion Beam Sputtering) method. Despite setting the composition of thin film Bi2212 or Bi2223, in both cases, Bi2201, Bi2212 and Bi2223 phase were appeared. It was confirmed the obtained field of stabilizing phase was represented in the diagonal direction of the right below end in the Arrhenius plot of temperature of the substrate and $PO_3$, and it was distributed in the rezone.

In this paper we write to the result of measuring human body shape method-ibs-2000 for human body shape measurement. The size measurement units and measuring speed is very inportant to efficiency of human body shape measurement units. By polygonal mirror system, the size measurement units and measuring time can be retrench.

Purpose: Irritable bowel syndrome (IBS) is frequently yet little understood disease. Review was performed to promote understanding on the characteristics, pathophysiology, and risk factors of IBS. Content: IBS is characterized by abdominal discomfort associated with pain and altered bowel function; structural and biochemical abnormalities are absent. Generally IBS is more prevalent in women and people with higher educational and social background, but there are some controversies. IBS is diagnosed by the Rome II or Manning criteria after excluding organic gastrointestinal diseases. The pathophysioloy is explained by abnormal control mechanism of central and enteric nervous system. Mucosal immunity, secretions, and neurotransmitter are also associated with the hypersensitivity and motility change of bowel function. Stress is known as a major triggering factor and contributed to symptoms. Other risk factors are genetic elements, childhood experiences, inflammation, anxiety, depression, diet, and sleep disorders.

70 MeV 사이클로트론의 인젝션 빔 라인은 Multi-CUSP 이온원에서 인출된 H- 빔을 펄스 또는 번칭하여 인플렉터를 통해 사이클로트론의 가속영역인 Dee로 전송하는 역할을 한다. 이 때, 빔을 번칭 시킴으로써 가속효율을 높이고, 손실을 줄여 높은 전류의 빔을 공급할 수 있도록 해야한다. 인젝션 시스템은 einzel lens, chopper, buncher, solenoid 등으로 구성된다. Einzel lens는 빔을 buncher의 중심으로 집속시켜 buncher의 번칭 효율을 높이고, buncher는 전기장을 이용하여 빔을 진행방향으로 집속시키는 기능을 갖는다. Chopper는 번칭된 빔을 일정 주기로 편향을 시켜 펄스 빔의 형태로 전송하는 역할을 한다. 솔레노이드는 적절한 자기장을 이용하여 빔을 집속시켜 인플렉터로 전송한다. 본 연구에서는 사이클로트론의 고전류 인젝션 시스템을 구축하고 각각의 구성요소에서 빔 envelope를 계산하고 비교하였다. SIMION code는 user가 지정한 특성을 가진 개별 입자의 궤도를 추적하는 프로그램으로 인젝션 시스템을 구성하는 각각의 컴포넌트에서의 입자의 진행모습과 buncher를 이용하여 빔의 전송 밀도가 향상됨을 확인하였다. 아울러 TRANSPORT 및 TURTLE 프로그램을 이용하여 SIMION을 통해 계산된 빔의 envelope과 비교하였다.

Objective : This study reports on the case of a patient with irritable bowel syndrome (IBS) diagnosed by the Shanghanlun disease pattern identification diagnostic system (DPIDS). We tried to verify the therapeutic effects of Soseunggi-tang (SSGT) administration and pathological character. Methods : The patient was administered SSGT for 31 days. We observed the progression of symptoms, patient compliance, and the presence of side effects. The progression of IBS was evaluated based the on Gastrointestinal Symptom Rating Scale (GSRS). Abdominal pain, flatus, visual findings, and patient statements were also assessed. Results : According to the DPIDS, the patient was diagnosed with Yangmingbing (陽明病). As a result, his GSRS score dropped from 15 to 5, the visual analog scale (VAS) score for abdominal pain lowered from 9 to 4, and the VAS score for flatus decreased from 8 to 4. The stool type changed from diarrhea to a loose stool form. Conclusions : SSGT showed therapeutic effects on the patient diagnosed with IBS and Yangmingbing.

The cryogenic system of RAON which is Korea's first heavy ion accelerator was numerically modeled and simulated. EcosimPro which is widely used off-the-shelf numerical software for a large scale cryogenic system was used for the simulation. The model of SRF TF cryogenic system, which is the testbed of cryomodule, was firstly established. The integrity of system of SRF TF was confirmed by comparison of simulation and experimental results. The cool-down strategy to minimize the thermal stress of the cavity was simulated and an optimal strategy was established. In addition, the influence of valve and pump control parameters on the cooling time was investigated, and optimal control parameters were also derived. The cryogenic system of SCL3 that is a low-energy acceleration section including 55 cryomodules, valve boxes, and helium supply lines was also modeled. The soundness of the thermal shield system and interlock system of SCL3 was investigated.
