차세대 네트워크의 출현으로 다양한 형태의 통신망 들 간의 융합이 중요해졌다. 무선 망의 경우 이질적인 망들 간의 통합 및 융합이 이루어지기 위해서는 끊김 없는 이동성 지원이 매우 중요하다. 끊김 없는 이동성 지원은 이질적인 무선망 간의 이동시에도 지속적으로 세션을 유지하는 기능을 말한다. 이러한 기능을 핸드오프 기법이라 하며 현재 다양한 연구가 진행 중이다. 본 논문에서는 현재 제안되어 있는 핸드오프 기법 중 USHA(Universal Seamless Handoff Architecture)를 기반으로 하여 적용하기 쉬우며 확장성과 신뢰성을 보장하는 핸드오프 모델을 제안한다.

According to continuous development of information technology, it is needed to make convergence of other disciplines such as humanities and area studies. Among convergence fields related to information technology and humanities/area studies, electronic cultural atlas represents various digitalized cultural information on electronic map using spatial data such as points, lines, and polygons through time, spatial, and subject axises. Knowledge map is to represent special academic information based on electronic cultural atlas. In details, knowledge map can provide integrated information sharing and spread because academic information associated with electronic cultural atlas and data related to per subjects, regions, and period become organically connected. Therefore, knowledge map may be utilized to promote scholastic research and diffuse research result. In this paper, we describe basic concept and composition of knowledge map and propose design method to construct knowledge map.

The technological convergence of IT, BT and NT is expected to drive technological revolution in the twenty first century, so a large amount of R&D expenditure is being concentrated on the development of fusion technology worldwide. Researches on how to direct and manage fusion technology development, however, are rare up to the present. This study investigates technology development and S&T human resources practices in the fusion technology are a focusing on the career path movement of researchers. On the basis of case study and a field survey of 209 scientists and engineers from academia, research institutes and industry, four strategic directions are recommended for improving human resources development in convergence technologies. The limitations and contributions of the study are also discussed.

The high-tech industry, a leader in the national economy, has a larger investment cost compared to general buildings, a shorter construction period, and requires continuous investment. Therefore, accurate construction cost prediction and quick decision-making are important factors for efficient cost and process management. Overseas, the construction information classification system has been standardized since 1980 and has been continuously developed, improving construction productivity by systematically collecting and utilizing project life cycle information. At domestic construction sites, attempts have been made to standardize the classification system of construction information, but it is difficult to achieve continuous standardization and systematization due to the absence of a standardization body and differences in cost and process management methods for each construction company. Particular, in the case of the high-tech industry, the standardization and systematization level of the construction information classification system for high-tech facility construction is very low due to problems such as large scale, numerous types of work, complex construction and security. Therefore, the purpose of this study is to construct a construction information classification system suitable for high-tech facility construction through collection, classification, and analysis of related project data constructed in Korea. Based on the WBS (Work Breakdown Structure) and CBS (Cost Breakdown Structure) classified and analyzed through this study, a code system through hierarchical classification was proposed, and the cost model of buildings by linking WBS and CBS was three-dimensionalized and the utilized method was presented. Through this, an information classification system based on inter-relationships can be developed beyond the one-way tree structure, which is a general construction information classification system, and effects such as shortening of construction period and cost reduction will be maximized.

Despite a quantitative increase in the export of small and medium sized businesses due to various policies supporting export that have been continually promoted by the government, the majority of export growth has been centered around conglomerates. As research has shown that export companies are superior in terms of job creation and growth compared to domestic companies, the conversion of domestic companies to export companies will not only result in job creation and increase in exports, but it will also enable the improvement of such companies. It is therefore important to support the export of small and medium sized businesses and maintain their status as export companies with supporting policies. The purpose of this study is to analyze the present state of the export environment of Korean and foreign small and medium sized businesses in order to elicit ideas for establishing strategies for the promotion of export and maintaining the status as an export company.

This study was performed to examine the effect of convergence-based simulation education on the problem solving ability and self-efficacy and confidence of core fundamental nursing skill performance for nursing students. A non equivalent control group post-test only design was utilized(experimental group(n=97), control group (n=87)). Data were analyzed using independent t-test, Chi-square test and Pearson's correlation. The scores of the problem solving ability(t=-2.04, p=.043) and confidence of core fundamental nursing skill performance(t=5.31, p<.001) were higher than those of the experimental group than control group. It is necessary to find ways to iterative and convergent research that verifies the continuous development and effectiveness of various courses.

The purpose of this study was to investigate relations among the non-verbal communication, coach trust, and continuous participating intention of scuba diving participants. For this purpose, the investigator applied convenience sampling to users at three scuba diving resorts in Gangwon Province and those at two scuba diving pools in Gyeonggi Province and selected total 267 valid questionnaires. Collected data was put to simple and multiple regression analysis with the SPSS 18.0 program. The findings were as follows: first, body language and paralanguage of non-verbal communication had significant effects on coach trust, but spatial acts and physical appearance had no such effects on it; secondly, coach trust had significant impacts on continuous participating intention; and finally, body language of non-verbal communication had significant influences on continuous participating intention, but spatial acts, paralanguage, and physical appearance had no significant influences on it.

최근 기후변화로 인한 극심한 홍수와 가뭄, 폭염 등 이상 기온 및 기후에 따른 피해가 급격히 증가하는 추세이다. 특히, 집중호우로 인해 도심지에서 발생한 홍수피해는 재산피해뿐만 아닌 수 많은 인명피해가 발생하고 있다. 국내에서는 수재해로부터 인명과 재산을 보호하기 위해 용수공급과 체계적인 치수 사업이 행한 바 있다. 이러한 치수 사업에서 경제성 분석은 사업 전·후 의 편익추정이 완벽히 검증되기 쉽지 않으며, 기존의 치수 계획은 유역 전반에 걸쳐 다양한 홍수 방어시설의 종합적인 고려 없이 제방 중심으로만 수립되어 홍수 발생 시 하천에 과도한 부담을 줄 뿐만 아니라, 사업의 경제성이 낮게 평가되고 있다. 이렇게 국내에서 행해진 하천설계기준에서 제안되었던 경제성 분석 방법은 여러 가지 문제점들을 내포하고 있으며 지속적인 홍수피해가 발생하였다. 이와 같은 문제점들을 개선하고자 개발된 K-FRM(Forean-Flood-Risk Model)은 능동형 하천정보 운영을 통한 다차원 하천관리체계 구축 및 활용을 위한 정량적 위험도 평가 툴로 위험지역에 노출된 자산의 정보(인벤토리), 평가기준, 손상함수, 계량화 원단위 등 홍수피해를 추정하는데 활용이 가능하며, 손실 또는 피해액으로 표현되는 재해손실은 경제적인 관점에서의 위험이며 금전적인 형태로 표현된다. 본 연구에서는 홍수피해액 정량화 모델인 K-FRM을 활용하여 굴포천 유역과 영강 유역을 대상으로 항목별 피해액 산정 후, 정량적 피해액 산정 방법인 EAD(Expected Annual Damage) 분석을 통해 홍수피해위험지도를 작성하여 표준유역별, 행정구역별 홍수피해액을 산정하는 것을 목적으로 한다.
