The International Civil Aviation Organization(ICAO) recently established the Global Aviation Safety Plan(GASP) for national aviation safety management, along with the enactment of Annex 19, Safety Management System(SMS). ICAO require the establishment of the 'States Safety Programs(SSP)' for countries with excellent safety evaluation, including Korea, and the establishment of aviation safety supervision systems for all Contracting States by 2017 under the enactment of ICAO Annex 19. Required. The Ministry of Land, Infrastructure, and Transport has continuously invested in R&D to secure such aviation safety systematically, and is making efforts to develop and disseminate related technologies by establishing long-term R&D roadmaps. A study on aviation safety supervision among the system-based aviation safety supervision support technology development R&D project, which is underway as part of the aviation safety technology development project of the Ministry of Land, Infrastructure and Transport. We conducted a study to see if this methodology logically guarantees reasonableness.

High-speed military aircraft shall be able to identify and resolve enemy threats or internal component defects with survival equipment and warning systems to minimize casualties. Warning system is divided into visual method with symbolic display and auditory method with communication equipment, which is superior in that they it has a short response time and does not cause pilot confusion by listening to simple messages. Thus, this paper suggested and evaluated effective design methods of voice/tone warning systems for military aircraft based on a life cycle perspective. Since military aircraft is safety-sensitive, priorities and three properties(Inhibitible, Interruptible, and Deactivatable) were applied to each warning to reflect criticality and urgency. As a result, we confirmed that it took 40ms to play the voice warnings, satisfying all requirements through V model-based development and testing, and improving product reliability.

Agile software development methodology is a lightweight software development method, plays an important role in the software development team. In this paper, we propose programs that in when agile development co-operation, team management, team collaboration and project management tasks can be high efficiency and allocation of human resources. The proposed model, the use of 6-Sigma priority assignment, established a mathematical model of the operation and distribution of human resources is the most reasonable people go to work. Cooperation makes team-based agile development can improve efficiency. This method improve staff efficiency by teamwork to improve the productivity of software development.

지난 100년간(1996~2005년)의 전지구 평균 온도는 $0.74^{\circ}C$ 상승하였고 이러한 온도 상승은 온실효과의 영향으로 파악되고 있으며, 장래에는 이러한 상승 경향이 가속화되어 진행될 것으로 예측되고 있다(IPCC 2014; Baek et al 2011). 전지구 기온 상승은 극한 해수면 증가 및 호우 빈도와 평균 강수량 증가로 나타나며, 이로 인한 상당한 홍수 및 침수피해 가능성이 나타나고 있어 이에 대한 선제적 대응책 마련이 필요한 실정이다. 본 연구에서는 GCMs 모델별 연 최대 일 강수량을 추출하여 정상성 및 비정상성 빈도분석을 수행하고 빈도별 확률강수량을 산정하였다. 정상성 및 비정상성 분석을 위해 모델별 연최대치 일강우 자료를 산정하고, 모델별 경향성 검정을 수행하였다. 또한 각 모델별로 2021년부터 30년을 기준으로 1개년씩 자료이동을 통해 30세트를 구성하고, 각 세트별 80mm 이상의 강우의 평균 발생횟수 및 여름철(6월~9월) 평균 강우 총량의 산정을 통해 순위 도출에 적용하였다. 경향성 검정 및 순위도출 결과를 토대로 8개 GCMs 자료 중에서 4개의 GCMs를 선정하였고, 시나리오별 세트구성에 따른 연 최대 일 강우량의 평균 및 Gumbel 분포형의 위치 및 축척매개변수를 산정하였으며, 이를 토대로 서울지역을 대상으로 위치 및 축척 매개변수 추정에 따른 비정상성 빈도분석을 수행하였다.

The purpose of this study is evaluate factor for risk management of hazardous substance at ports. The analysis was conducted by applying Fuzzy-AHP methodology, through a questionnaire for hazardous substance experts from Busan, Gwangyang, Incheon, and Ulsan, which are the major Korean ports. Three measurement areas and nine sub-factors were selected for the study. The results of this analysis showed that "human resource management" (HR) was the most important factor (0.445) in the three measurement areas. After applying the conversion weight, the sub-factors were ranked according to their priority as follows: "a secure of administrator skill" (0.158) had the first rank, "an improvement in administrator duty" (0.150) had the second, and "consolidation of safety education" (0.136) had the third rank.

This study analyzed the Entrepreneurial Competencies of Science and Technology Personnel from the point of view of the industry's demanders. It is necessary to change institutional and policy support from quantitative support to improvement of qualitative level. Specifically, this study used the Borich's Needs Assessment Model to determine what capabilities are currently lacking and which should be supplemented. As a result of analysis, it showed that the current level was lower than expected level. Especially, expectation level was high in order of team working, problem solving ability, communication, abstract thinking, job knowledge, Autonomy, leadership, risk-taking, and commercialization are all lower than the overall average. In the analysis of educational need, the most important factor of entrepreneurial competence appeared in order of problem solving ability, teamworking, job related knowledge, abstract thinking, and communication. This means that it is necessary to logically solve the problems that are encountered in various situations in the organization by using cooperation between the teams and their own job knowledge. In addition, education should be conducted to effectively communicate the results to others.

We propose a two-stage Distributed Denial of Service (DDoS) defense system, which can protect a given subnet by serving existing flows and new flows with a different priority based on IP history information. Denial of Service (DoS) usually occurs when the resource of a network node or link is limited and the demand of the users for that resource exceeds the capacity. The objective of the proposed defense system is to provide continued service to existing flows even in the presence of DDoS attacks. The proposed scheme can protect existing connections effectively with a smaller memory size by reducing the monitored IP address set through sampling and per-prefix history management. We evaluate the performance of the proposed scheme through simulation.

This study was conducted to identify and analyze the educational needs for program outcomes in nursing students. Participants included 256 nursing students at K college, and a survey was conducted from October 30 to December 22, 2017. Data was analyzed with SPSS WIN 20.0 using descriptive statistics, t-test, ANOVA, Borich's Needs Analysis, and the Locus for Focus Model. Results found that subjects recognized that the present level was high about 'Apply therapeutic communication skills,' 'Provide fundamental nursing skills' and 'Understanding nursing profession standards'. 'Provide fundamental nursing skills', 'Apply a nursing intervention', 'Understanding legal and ethical standards of nursing practice and implementation' were the most important sub-elements of program outcomes. In according with the Borich's needs value and the Locus for Focus Model, 'Apply a nursing intervention', 'Explain the importance of the role and cooperation within the healthcare team', 'Provide fundamental nursing skills', 'Execute the nursing process', 'Understanding the legal and ethical standards of nursing practice and implement' were identified as the top priorities of educational needs. Results of this study are expected to be used as basic data to develop outcome-based curriculum and nursing education programs.
