The creation of academic start-up firms is an important and practical issue in the management of technology in Japan. The present study designs a model for creating academic start-up firms that fits into the social context. It focuses on the case of FIRST Program, an initiative that consists of 30 projects in innovative arenas, analyses the presence of large-scale public funding, and investigates the role of venture capitalists as support personnel in each project. As a result, the presence and significance of 'long-term escort' by an 'entrepreneurial venture capitalist (EP-VCist)' were confirmed as common features across the cases observed. EP-VCist refers to a person who can maintain and fulfil dual roles at a university and a venture capital firm, and who can take the lead throughout the venturing process as a risk taker. 'Long-term escort' is a form of support that reduces risks in the venturing process by supporting university researchers in the pre-entrepreneurial stage and by exerting a robust bridging role between a university and an industry.

Somalian pirates with the onset of civil war in the early 1990s have caused a threat to international transportation. Various international organizations including the International Maritime Organization and the World Food Program are concerned about this problem. The cost of shipping is increasing and food-aid shipment is hindered by these ships are needed military escort. Since 2008, international society has deployed multinational naval vessel in the nearby Somalian sea and strengthen multinational naval operations to minimize damages from piracy.

최근 개인정보유출 사건이 빈번히 발생함에 따라 개인정보보호의 문제는 우리 사회의 가장 중요하고 민감한 사회적 의제로 급부상하고 있다. 실제로 개인정보는 그 종류나 유형, 경제적 가치와 민감성, 정보의 질 등에 따라 유출 시 심각한 사회적 위협을 야기할 수 있기 때문에 보다 정확하고 체계적인 개인정보보호 및 관리가 이루어지지 않을 경우 정보화 사회에 큰 혼란을 초래할 수 있다. 특히 업무에 있어 고객의 민감한 개인정보를 필요로 하는 중소 경호 경비업체의 경우, 수집한 정보가 유출 될 시 고객 신변이나 업체의 영업 비밀이 외부에 노출 되 심각한 위협이 있을 수 있어 더욱 큰 문제를 야기한다. 그러나 중소 경호 경비업체는 대기업에 비해 자금의 정도, 인력 부족 등의 문제로 인하여 자체 보안 시스템 구축에 많은 어려움이 있다. 따라서 본 연구에서는 경호 경비업체의 실정을 살펴보고, 그 중 중소 경호 경비업체들이 차지하는 규모와 정보보호의 현황, 특징들을 분석하여 정보보호 시스템 마련의 현실적 문제점 해결 방안으로 중소 경호 경비업체의 개인정보유출 방지를 위한 보안체계를 제안한다.

함정 전투체계는 각종 센서 및 무장을 포함한 플랫폼들을 효율적으로 통제하기 위해서 운용자의 개입을 필요로 한다. 이러한 문제점을 극복하기 위해서 다중 에이전트 기반의 M&S(Modeling and Simulation) 기술이 도입되어 다양한 연구가 이루어져 왔다. 하지만 다중 플랫폼간의 높은 임무 복잡도를 필요로 하는 대 잠수함 전투에 있어서는 M&S 시스템을 통한 전술에 관한 연구가 거의 진행되지 않은 실정이다. 본 연구에서는 다중 에이전트 기반의 M&S 기술을 대 잠수함 전투에 적용하였다. 이를 위해 함정, 잠수함, 헬기 등 다수의 플랫폼을 에이전트 기반으로 모델링함으로써 HVU(High Value Unit) 호위 임무를 위한 모델 구조를 제시하였다. 이를 통해 다양한 전장상황에 대한 다양한 전술 효과도를 분석할 수 있었다. 그 결과 조건별 최적의 전술적 효과를 확인할 수 있었다. 국방 관계자들이 본 연구에서 제안한 방법론을 도입하여 상세한 모델 변수값들을 대입한다면 보다 실질적인 대 잠수함 전술 효과도를 분석해 낼 수 있을 것으로 기대된다.

Background: Many critically ill patients require transfer to a higher-level hospital for complex medical care. Despite the publication of the American Academy of Pediatrics guidelines for pediatric interhospital transportation services and the establishment of many pediatric transport programs, adverse events during pediatric transport still occur. Purpose: To determine the incidence of adverse events occurring during pediatric transport and explore their complications and risk factors. Methods: This prospective observational study explored the adverse events that occurred during the interhospital transport of all pediatric patients referred to the pediatric intensive care unit of Ramathibodi Hospital between March 2016 and June 2017. Results: There were 122 pediatric transports to the unit. Adverse events occurred in 25 cases (22%). Physiologic deterioration occurred in 15 patients (60%). Most issues (11 events) involved circulatory problems causing patient hypotension and poor tissue perfusion requiring fluid resuscitation or inotropic administration on arrival at the unit. Respiratory complications were the second most common cause (4 events). Equipment-related adverse events occurred in 5 patients (20%). The common causes were accidental extubation and endotracheal tube displacement. Five patients had both physiologic deterioration and equipment-related adverse events. Regarding transport personnel, the group without complications more often had a physician escort than the group with complications (92% vs. 76%; relative risk, 2.4; P=0.028). Conclusion: The incidence of adverse events occurring during the transport of critically ill pediatric patients was 22%. Most events involved physiological deterioration. Escort personnel maybe the key to preventing and appropriately monitoring complications occurring during transport.

In recent warfare, the performance improvement of air weapon systems enables an aircraft to strike multiple targets on a single sortie. Further, aircrafts attacking targets may carry out an operation as a strike package that is composed of bombers, escort aircrafts, SEAD (Suppression of Enemy Air Defenses) aircrafts and etc. In this paper, we present an aircraft allocation model that allocates multiple targets to a single sortie in the form of a strike package. A mixed integer programming is developed and solved by using a commercially available software. The new model is better than existing ones because not only it allocates aircrafts to multiple targets but also it models the concept of the strike package. We perform a computational experiment to compare the result of the new model with that of existing ones, and perform sensitivity analysis by varying a couple of important parameters.

The probability of target survival is the most important factor in the target assignment, Most of the studies about it have assumed the case of one target and ane weapon type. Therefore, they can not be applied to the real situation. In this paper. the quantity and type of enemy assets of the friendly force are considered simultaneously. Considered defense type is the coordinated defense with no impact point prediction. The objective function is to minimize the expected total survival value of targets which are scattered in the defense area. The rules of aircraft assignment are as follows : first, classify targets into several groups, each of those has the same desired damage level secondly. select the critical group which has the least survival value in accordance with the additional aircraft assignment, and finally. assign the same number of attack assets against each target in the critical group. In this paper, the attack assets, the escort assets, and the defense assets are considered. The model is useful to not only the simple aircraft assignment problem but also the complicated wargame models.

In this paper, we wish to construct a optimal traffic cycle using wire remote control. if police vehicle or ambulance suddenly enter the traffic Intersection, it will increase the traffic accident. In this paper, wireless traffic light use the radio traffic control signal and research about the hardware manufacture to check special detectors on urgency vehicles may safety and rapidly enter traffic intersection. Also, this paper present a traffic signal control conditions that analyzes different traffic intersection flows in cases of saturated flows, where the real traffic volume demand is large and the capacity constraints of bottlenecks have significant effects on the flow patterns. Through computer simulation this wireless traffic light has been proven to be much more safety and efficient than fixed traffic signal light which does not consider emergency vehicles for safety escort.

최근 몇 년간 IT분야의 키워드는 소셜 네트워크 서비스 (SNS)와 스마트이다. 이러한 시대 흐름에 맞추어 지도와 GPS를 이용한 다양한 어플리케이션들이 개발되고 있지만, 대부분의 어플리케이션들이 단편화된 지리 정보만을 제공해주고 있다. 특히, 애플리케이션의 서비스형태가 프로슈머 기반으로 바뀌는 패러다임의 상황에서 아직까지 일반적인 애플리케이션 서비스형태가 생산과 소비를 분리해서 제공하고 있어서 본 논문에서는 프로슈머 기반의 애플리케이션 서비스 시스템을 개발하고자 한다. 특히, 여행가이드 서비스를 제공하는 애플리케이션을 대상으로 안드로이드 기반에서 지도서비스와 문서작성 편집 기능이 웹과의 연동을 통해, 다양한 방식으로 호환이 가능한 시스템을 개발하고자 한다. 또한 이를 통해, 기존의 활용되는 애플리케이션의 단점을 극복하고 양방향 서비스가 가능하게 하고자 한다.
