온라인 디지털 콘텐츠 산업에서 포털은 콘텐츠의 생산, 유통 및 이용 등 산업의 가치 활동의 선순환을 위한 핵심기업으로 활동하고 있으며, 각 포탈마다 특유의 공급 사슬을 구성하고 있다. 최근에 급변하는 온라인 디지털 콘텐츠 시장 환경에서 지속적인 경쟁력을 확보하기 위해 포털 공급사슬관리가 점차 중요해지고 있다. 하지만 온라인 디지털 콘텐츠 산업의 공급사슬관리에 대한 선행 연구가 매우 미흡하다. 따라서 본 연구에서는 물리재를 생산 공급하는 전통적인 공급사슬관리와 온라인 시장에서 디지털 정보재의 생산과 유통을 촉진하는 포털 공급사슬관리에 대한 근본적인 차이점을 규명하고, 포털 공급사슬의 설계 및 이행을 성공적으로 수행하기 위한 연구이슈를 규명하고자 하였다. 연구결과, 포탈 SCM의 가치영역 프레임워크 도출, 포탈 이용자예측방법과 참여기업 간 예측정보 공유 방안, 포털 SCM에서의 채찍효과의 특성 및 관리방안, 포털 SCM에서 콘텐츠 소싱의 복잡성 해결방안, 포털 SCM에서의 재고관리의 요소 및 관리방안 등에 대한 연구문제가 도출되었다.

This research paper delved into the availability and utilization of library portal services for research in university libraries in Nigeria. Two research questions and two null hypotheses were formulated to guide the study. A structured questionnaire was used for data collection. The study was carried out in Nnamdi Azikiwe Library, University of Nigeria Nsukka (UNN) and Felix Aghagbo Nwako Library, Nnamdi Azikiwe University Library (UNIZIK), Awka. A total of 70 professionals (librarians and system analysts) in these libraries supplied data for the study. Data collected was analyzed using mean and standard deviation. These were used to answer the research questions while the null hypotheses were tested using t-test statistic at 0.05 level of significance and 68 degree of freedom. Major findings showed that portal services available in the library showed that the areas of availability of library portal services in Nnamdi Azikiwe Library, U.N.N. includes Agriculture, Health Sciences, Engineering, Environmental Sciences and information about institution, Social Sciences, Arts and Humanities, Natural Sciences. In Festus Aghagbo Nwako Library, Awka, the areas of Portal Library Services include Career Development, Federal Government Programs, Environmental Sciences, Biological Sciences, Social Sciences, Arts and Humanities, Engineering, and Health Sciences. Findings on extent of utilization of portal services available in the libraries indicated that portal services are utilized to a low extent in the university libraries. Furthermore, librarians did not significantly differ in their opinions on the availability of library portal services and on the extent of utilization of library portal services in the libraries under study. It is therefore recommended that provisions should be made by the universities and library management to provide and update required portal services in addition to creating enabling environment for enhanced access and utilization of these services. The governments must make an effort to provide funds for policy implementation, necessary technology training for librarians and users, and develop general information infrastructure.

공공데이터 포털(data.go.kr)은 우리나라 공공데이터 검색과 활용을 위한 통합창구이다. 2021년 행정안전부는 개별 포털 정비방안을 수립한 바 있다. 개별 포털은 공공데이터 외 국내 공공기관들이 구축한 포털을 통칭하는 표현이다. 정비방안에 따라 공공데이터 포털 운영 주체인 한국지능정보사회진흥원은 공공데이터 포털과 개별 포털을 연계하기 위한 운영 및 데이터 연계방안 수립이 필요하다. 이에 본 연구에서는 우리나라 공공데이터 포털, 미국, 영국, 프랑스 데이터 포털 운영현황과 데이터 연계방식을 조사하여 데이터 연계 시 상향식 방법 채택이 효율적임을 제안하였다. 또한, 연계 시 추진해야 하는 구체적인 절차를 데이터 연동 표준방식 결정, 메타데이터 현황분석, 운영 인프라 확충, 데이터 반입 확인, 서비스 개시 5단계로 나누어 제시하였다.

Details are given of a cold-formed steel portal framing system that uses simple bolted moment-connections for both the eaves and apex joints. However, such joints function as semi-rigid and, as a result, the design of the proposed system will be dominated by serviceability requirements. While serviceability is a mandatory design requirement, actual deflection limits for portal frames are not prescribed in many of the national standards. In this paper, a review of the design constraints that have an effect on deflection limits is discussed, and rational values appropriate for use with cold-formed steel portal frames are recommended. Adopting these deflection limits, it is shown through a design example how a cold-formed steel portal frame having semi-rigid eaves and apex joints can be a feasible alternative to rigid-jointed frames in appropriate circumstances.

For a partial tear of the subscapularis tendon, the presenting technique requires only the anterior portal for preparing the footprint and suture management, as well as the subclavian portal for placing the suture anchor and suture hook without inserting a cannula. It provides both a good angle for anchor placement and sufficient space for managing the upper portion of a subscapularis tendon tear. A spinal needle was inserted through the subclavian portal in order to identify the appropriate angle for placing the suture anchor. A 3-mm incision was made for the subclavian portal and a biosuture anchor was placed on the footprint portion of the subscapularis tendon. In order to avoid crowding, each limb of both strands of the biosuture anchor were passed through the tendon- posteromedial side first, and anterolateral side second, using a switching technique with suture hook embedded with no.1 PDS. A suture tie was applied in a reverse sequence (the lateral strand first and the medial strand second) through the anterior cannula using a sliding technique.

The demand of tunnels has been increased for the linear improvement of general national highway, and road construction and/or enlargement in Korea. Also, the collapses of tunnel portal slope have been increased in recent due to heavy rain caused by global warming. Therefore, it has been risen the requirement of system for the stability of tunnel portal slope in Korea as well as all over the world. The objective of this research is to develop an effective maintenance system for supervising the tunnel portal slope. This paper is a basic proposal to execute a survey on the current status and state of the tunnel portal slopes that were already installed along general national highways.

The Cutting slope is to be minimized when a tunnel meets the contour of slope terrain at a right angle around its portal. However, a tunnel portal has been generally installed at a right angle to the longitudinal axis of a tunnel with no consideration of the intersection angle with the slope terrain. This sometimes tended to cause huge cutting slope that resulted in many disadvantage in terms of safty, economy and environment. Therefore, the minimization of cutting slope is studied by taking the intersection angle into account, and the result is compared with that by the conventional method. In addition a design method for the inclined portal to the tunnel axis is proposed through 3D-FEM analysis, also the applicable ground condition is suggested.

Internet portal sites have served customers for more than a decade in Korea. There have been several such sites have survived, succeeded and led the internet industry. What is the source of their competitiveness? We assumed that the network effect, which can vary dynamically, is an important factor; so we tried to build and analyze a system dynamics model on portal sites that represent their advertising business model. This model includes not only the network effect, but also customer's' expectations of the quality of portal sites, which also varies dynamically. As a result of our research, we can state that the network effect is important to stabilize and increase portal sites' quality, market share, income and cash flow. And we know that investment at a level above that which is merely required is necessary to preserve and stabilize their business.

This research develops, and empirically test a model for explaining/predicting the Determinants and Satisfaction of Portal Cite in Internet Initiation Page. Also this paper describes a theoretical model for investigating the service quality satisfaction in the Internet Initiation Page. This research is the first to empirical test the causal relationships in determinants of Portal Cite. The model of the satisfaction for Portal Cite are tested here using data from 224 samples. Based on the research model, a comprehensive set of hypotheses is formulated and a methodology for testing them is outlined. some of the hypotheses are tested empirically to demonstrate the applicability of the theoretical model. In examining the relationships of the determinants factors, satisfaction show in significantly by Convenience, Information Provided, Entertainments, Interaction but that show in not significantly by the Trustworthiness, In addition, Portal Cite in Internet Initiation Page shows indirect effect between customer satisfaction and referral.
