Slope Based Intelligent 3D Disaster Simulation Using Physics Engine
Kim, Joo-Chang,Jung, Hoill,Kim, Sungho,Chung, Kyungyong Kluwer Academic Publishers 2016 WIRELESS PERSONAL COMMUNICATIONS Vol. No.
<P>In the modern society, the forms of disasters are getting larger and more diverse by abnormal weather phenomena due to rapid social changes. As human and economic damage is increasing by these disasters, interest in disaster observation and prevention is increasing and studies have been carried out in various fields. In order to minimize disaster damage, National Disaster Information Center provides disaster-related information such as disaster situations, risk index, local situation and so on. At present, however, various descriptive studies on action tips in the event of a disaster, disaster alert, disaster communications network have been in progress but there are few studies on prediction or simulation for preventing disasters etc. Therefore, this paper proposes a slope-based intelligent 3D disaster simulation using a physics engine. The proposed method is to infer a variety of disaster situations that may occur in reality through ontology and apply it to 3D simulation. Disaster situation ontology constitutes context information of outside, inside, disasters etc. and generates rule bases using Jena 2.0 inference engine. Inference results are derived in the form of XML and applicable to a variety of devices. The expression of 3D simulation virtual space is divided into interior and exterior. Interior constitutes the index information based on actually measured terrain and then expresses it into 3D compound type terrain data. Exterior expresses six planes into a hexahedron by using Sky Box technique. Simulation operates object collision, movement, surroundings etc. in real time by using a physics engine and represents a disaster situation in 3D virtual space by using particles function. Based on ontology based context awareness, environment context information on slope, including landslides, snow, rain, fogs, fire, explosion, and smoke, is developed into the slope based intelligent 3D disaster simulation. As a result, depending on geomorphic characteristics, disaster management service can realistically and visually be offered to users in 3D virtual reality. In addition, it is possible to experimentally apply disaster situations virtually through 3D virtual reality, and thereby judge their potential risk.</P>

KIM, KYUNGYONG 한국당과학회 2018 한국당과학회 학술대회 Vol.2018 No.07
Abcertin was developed as orphan drug, a new enzyme replacement therapeutic product which is imiglucerase for Gauchers patient's therapy in Korea. Glycosylation is a one of critical quality attributes for Imiglucerase. In this slide, the useful tools and approaches are shown for glycosylation analysis for imiglucerase in aspect of therapeutic protein development. And some of case study for Structure and function relation ship for glycosylation characterization will be introduced.

Background: Chronic obstructive pulmonary disease (COPD) is a chronic respiratory disease characterized by persistent airflow limitation. Therefore, both work ability and workday length may be affected in individuals with this disease. We studied a worker with suspected COPD and assessed fitness to work using post-bronchodilator spirometry, symptom assessment scales, and the exercise stress test. Case report: The patient was a 58-year-old man due to work as a field supervisor in the ship construction sector. He had a 40 pack-year smoking history and experienced occasional dyspnea when climbing stairs. He visited this hospital to receive cardiopulmonary function tests and to determine his ability to work. Post-bronchodilator spirometry revealed severe irreversible airway obstruction corresponding to a modified Medical Research Council grade of 2 on the dyspnea scale. His COPD Assessment Test score was 12, placing him in patient group D (high risk, more symptoms) based on the Global Initiative for Chronic Obstructive Lung Disease classification system. His maximum oxygen uptake (VO2max) was determined to be 19.16 ml/kg/min, as measured by the exercise stress test, and his acceptable workload for 8 h of physical work was calculated to be 6.51 ml/kg/min. His work tasks required an oxygen demand of 6.89 ml/kg/min, which exceeded the acceptable workload calculated. Accordingly, he was advised to adjust the work tasks that were deemed inappropriate for his exercise capacity. Conclusion: As COPD incidence is expected to rise, early COPD diagnosis and determination of fitness to work is becoming increasingly important. Performing the exercise stress test, to evaluate the functional capacity of workers with COPD, is considered an acceptable solution.

본 논문에서는 시장 도입단계에 있는 무선 LAN 서비스가 본격적으로 시장성장을 이루기 위한 통신사업자의 시장개발전략 방향을 제시하였다. 이를 위한 선행작업으로써 무선 LAN 시장규모 및 전망을 살펴보았고 포터(M, Porter)의 산업분석 모형을 통해 국내 무선 LAN의 산업구조와 시장 성장동인을 분석하였다. 이를 바탕으로 도출된 통신사업자의 시장개발전략을 살펴보면, 1) 신규 통신서비스 성공 및 실패사례를 벤치마킹하고 2) 브리징 통신서비스의 특성에 적합한 전략을 적극적으로 반영하며 3) 고객지향적인 서비스의 개발 및 마케팅전략이 필요하다. 또한 4) 시장성장 동인을 바탕으로 기회요인은 강화하고 위협 요인은 조기에 해결해야 하며 5) 가치전달시스템내의 참여기업들간의 상호적인 협력과 제휴를 중요시 해야한다. 이와 같은 무선 LAN 시장개발의 전략적 방향설정은 통신사업자들에게 마케팅과 서비스 개발에 있어서 전략적인 시사점을 제공할 것이다.
