This research studied how game contents related experts recognize the transition of contents industries in intellectual information era. This study also studied experts' priorities of evaluation elements in contents industry policies. For this, Analytic Hierarchy Process was utilized to analyze the relative importance and priorities of evaluation elements in contents industry policies. According to the analysis, the order of priorities was 'strengthening content technology', 'training content experts', 'improving the contents-related system' and 'strengthening content usage and consumer safety'. Also, in complex importance analysis, 'strengthening R&D system for content' was gauge as the most important element. In the analysis about each related group's thinking, industries and policy institutes considered 'strengthening content technology' important and academia evaluated 'training content experts' as the most important one.

RFID 기술의 신속한 확산을 위해서는 태그의 저가격화, 초소형화, 저전력화, 보안 및 프라이버시 문제, 태그식별자의 표준화, 다중태그 식별문제등이 우선적으로 해결되어야 한다. 특히, 식별영역 내에 다수의 태그가 존재할 경우에 다중태그 식별(multi-tag identification)을 위한 충돌방지(anticollision) 알고리즘은 RFID 시스템 구축에 있어서 반드시 해결해야 하는 핵심기술이다. 기존의 충돌방지 알고리즘들은 구현의 복잡성과 낮은 성능이 문제로 제기되고 있으며 지금까지 충돌방지와 관련하여 진행된 대부분의 연구들은 각각 고유한 형태의 태그식별자 체계를 기반으로 진행되어 왔으며 태그식별성능에 대한 비교연구도 부족한 상태이다. 본 논문에서는 저비용(low-cost) RFID 시스템에서 현재 표준화가 진행되고 있는 96비트 EPC (Electronic Product Code) 코드를 기반으로 병원 환경에서 태그에 우선순위를 부여하여 충돌이 발생하면 우선순위가 가장 높은 것부터 읽어들일 수 있는 그룹 트리 알고리즘을 제안하였다.

There are many questions about the sustainability and nurture of social enterprises as an important governmental issue in Korea. But because of the social system and the deficiency of experience about social enterprise, the solution of problems included in social enterprise are very difficult. For these reasons, the purpose of this paper is to find critical factors on social enterprise policy in Korea. For this study 30 experts who work in various fields in Busan about social enterprise was selected and 23 valuable questionnaires was collected. And AHP analysis suggests critical factors(public procurement and partnership with corporation and various organizations) on social enterprise policy in Korea. When we consider many realistic problems for the social enterprises, just depending on the passion and dedication of social entrepreneurship is highly insufficient for the sustainability of social enterprises Effective and strategic governmental support for social enterprises will be a great help to the development and sustainability of social enterprises. In this sense, results of this study is meaningful to the social enterprise policy maker.

u-City(ubiquitous city) pursuing competitiveness of city and improvement the quality of life needs high cost to build and operate it. But not all people get a benefit by u-City. It is important that low-income people have experienced information divide gain practical benefits in u-City. In this paper, first we selected suitable item of u-service for low-income people and then drew a order of priority using AHP method about legal and institutional conditions, possibility of technical realization, and the generalization. As a result, we prioritize to u-service for low-income people, that is the order is prevention for missing a dotard, safety of street, and information providing about job and employment.

Recently, the I/O performance of a single node is rapidly improving due to the advent of high-performance SSD. As a result, the next-generation storage platform based on SSD has received a great deal of attention and such storage platforms are increasingly adopted to commodity servers or data centers that look for the high-bandwidth computation and I/O. However, building all SSD-based storage platform may not be cost-effective because the price per storage capacity is very high as compared to that of HDD. In this paper. we propose a hybrid file management solution, called HyPLVM(Hybrid Priority Logical Volume Manager), which combines the strength of SSD with the desirable aspects of low-price, high-storage capacity HDD. HyPLVM prioritizes the files and directories to be accessed by users, in order to determine the target storage device (SSD/HDD) in which files are allocated, while mitigating the cost of building storage platforms.

This study aims to build an AHP model that evaluates the priority of cyber security policies for the Azerbaijan information system. For this, 4 factors were constructed from components of ITU National Interest Model, whereas 5 alternatives were based on the best practices of the eight developed countries leading the cyber security field. Using the questionnaire, 24 security experts evaluated the strategic priority of such factors or alternatives. The analysis results using the AHP software showed that homeland defense and economic well-being were the dominant aspects of cyber security policy, whereas capacity building and infrastructure were the main concern of cyber security elements for Azerbaijan. This study presents the strategic priority of cyber security policies that can be adopted by Azerbaijan government. This study can contribute to developing the national cyber security guide of Azerbaijan.

Purpose: The purpose of this research is to develop an evaluation index for reliable information provision and operation management of traffic safety facilities. Method: As for the analysis method, evaluation indicators were selected by grasping the current state of operation and management of traffic safety facilities, and the importance of each indicator was analyzed through the AHP survey. Result: As a result of the comprehensive importance analysis, it was found that the highest priority was given in the evaluation index for information accuracy and computer system construction. On the other hand, the evaluation index corresponding to the service management was analyzed as having the lowest priority. Conclusion: The results of this study are expected to serve as a yardstick for understanding the management level of each institution for efficient operation and management of traffic safety facilities, and it is expected to establish a foundation for providing accurate information in consideration of the commercialization of autonomous driving in the future.

우리나라는 현재 개발되어 적용되고 있는 홍수피해잠재능(Potential Flood Damage, PFD) 산정방법은 잠재성요소(인구, 자산, 사회기반시설, 도시화율)와 위험성요소(홍수피해액, 확률강우량, 외수방어능력, 댐 및 저수지, 내수방어능력)로 산정 후 지역평가를 통해 그룹(A,B,C,D)별로 평가하고 있다. 하지만, 홍수피해잠재능(PFD) 산정인자가 많아 자료조사 및 구축에 많은 시간이 소요 되며, 인자별 다양한 공간적 범위로 인해 실무 적용에 어려움이 있다. 또한, 소구역 단위 평가로 인해 하천의 침투 특성을 반영하지 못하여 하천 주변의 중요도 평가가 미흡한 실정이다. 이를 위해 본 연구에서는 중요도 분석 인자 단순화를 통해 자료 조사 및 구축 시간 단축과 더블어 위험성요소를 내포하는 홍수위험지도 사용을 통해 작업을 간소화하고, 하천 주변까지 고려하여 중요도 평가하는데 목적이 있다. 본 연구에서는 낙동강권역을 대상으로 홍수위험지도 및 중요도 분석 인자(인구, 자산(공시지가), 시회기반시설(도로,철도), 도시화율(시가화지역)) 공간정보를 구축하였고, 점수할당법에 의한 인자별 중요도 분석 및 상관성 분석을 통해 피해우선순위를 분석하였다. 분석결과, 인구·자산(공시지가) 인자가 높은 구역이 대체로 사회기반시설 연장 및 도시화 면적이 높게 나타났으며, 하천의 치수단위 구역별 중요도 분석시 인구·자산(공시지가) 두가지의 인자로도 치수안전도 결정에 활용이 가능할 것으로 판단된다.

전국 주요 산단 지역에서 현재 유통되고 있는 화학물질의 스크리닝 수준에서의 생태 위해성 평가를 수행하고, 체계적인 위해도 분석 시스템을 구축하기 위한 수생 및 육상 생태계가 통합된 생태 위해성 예측 모형을 개발하였다. 전국 118개 공단 중 시화반월, 전주, 대전, 대구, 청주, 울산, 구미, 여천공단 등 8개 주요 산단 지역을 program 개발을 위한 비교 대상 지역으로 선정하였고 이들 공단에서 사용되고 있는 약 1700여종의 화학물질의 물리 화학적 특성 자료와 생태 독성값의 문헌치, 추정치를 포함한 database를 구축하였다. 구축된 database를 활용하여 산단별, 화학물질별 생태 위해도를 상대적으로 비교한 결과 어류 만성의 위해도는 청주 공단>울산미포>여천 공단의 순이었고, 물벼룩 만성의 위해도는 시화반월>여천>울산미포 공단의 순이었다. 또한 산단별로 위해도 우선순위 물질을 선정하였으며 styrene, xylene 등의 위해도가 높게 나타났다. 이때 화학 물질의 수계 배출량은 TRI 자료와 사용량과의 상관관계로부터 구한 배출 계수를 적용하여 산정하였으며, 선정된 위해도 우선 순위 물질을 대상으로 실제 공단의 하천 시료를 채취, 분석하여 이 모형에 의해 예측된 생태 위해도의 타당성을 검증하고 보완하는 연구를 지속적으로 수행하여 예측 program의 신뢰도를 높이고자 한다.
