전자상거래는 유통업의 형태를 바꿀 정도로 엄청난 기술혁신이지만, 적어도 앞으로 상당기간, 산업적인 성과는 기대이상으로 그렇게 커 보이지 않는다. 기술혁신이 분명 존재하였건만 이 효과를 가로막는 다른 한계들이 있기 때문이다. 바로 이러한 한계가 무엇인가를 보다 집중적으로 분석하고자 한 것이 본고의 목적이다. 이는 전자상거래가 어떻게 하면 성공할 것인가를 살펴보는 것과도 일맥 상통한 것이다. 본고는 종전의 전자상거래 분석 관점과는 달리 유통 전문가적인 시각을 견지한다. 유통 전문가적인 시각이란 유통업적인 관점이고 유통업체를 바탕으로 한 관점이다. 유통업적인 입장을 강조하기 위해 본고는 먼저 점포도 불필요하고 인건비나 관리비를 절감할 수 있다는 전자상거래가 오히려 전통상거래보다 비싸다는 점에서 출발한다. 그리고 매입의 문제, 택배비용의 문제, 거래의 신뢰성 문제, 시장기반의 문제 등이 있다는 점을 지적한다.

With rapidly changing technological implementation of operating systems of businesses, the Ministry of foreign affairs (MOFA) of the Republic of Korea (ROK) has been undergoing digital transformation to its overall operations with the intent to innovate information and knowledge management (IKM) strategies since the mid-2000s. However, assessment as to the effectiveness of implemented IKM has been inadequately analyzed. This study aims to assess the concepts and limitations of the MOFA's current IKM strategies and the methods it employs to deliver its IKM framework, in light of strengthening the organizational ambidexterity and absorptive capacity, and also fostering organizational innovation through a qualitative study that involves interviews and analysis of reports from MOFA. The MOFA's IKM possesses dynamic capabilities to adapt to changing digital technologies. However, the institution's IKM is constrained by limitations associated with the utilization of the IKM system such as a structure that handles confidential documents and a lack of a collaborative system for IKM, and external limitations such as changes in the domestic political situation governing MOFA's priorities and the hierarchy of government organizations. Consequently, developing the organizational ambidexterity and absorptive capacity was not possible. To develop an IKM framework for organizational innovation, the MOFA must devise a way to minimize the impact of external changes by overcoming internal limitations. To that end, a detailed study on the development of a practically usable IKM system should include establishing a dialogue between job groups and enhancing employee competency in preparation for a changing environment.

Member force, strain and stress distribution of a section are obtained for prestressed steel and concrete(PSSC) composite bridge subjected to dead and live load in order to interpret the effect of prestressing and deformation of tendon. The stress and strain distribution and moment capacity are obtained for both noncomposite and composite section and for allowable stress limit state, yield limit state and strength limit state. Reliability analysis is conducted after assuming limit states for deflection, stress and flexural strength. Comparing that the reliability index for stress is near 0 for example section which is designed to satisfy the allowable stress exactly, the reliability indexes for deflection and flexural strength are high. Reliability of PSSC girder which is designed based on allowable stress of bridge design code is high for deflection and flexural strength.

Member force, strain and stress distribution of a section are obtained for optimized standard 25m~45m PSSC composite bridge subjected to dead and live load in order to interpret the effect of prestressing and deformation of tendon. The stress and strain distribution and moment capacity are obtained for both noncomposite and composite section and for allowable stress limit state, yield limit state and strength limit state. Reliability analysis is conducted after assuming limit states for stress and flexural strength. The reliability index for standard PSSC composite bridge which is designed to satisfy the allowable stress for flexural strength are higher than 3.5 which is required reliability indexes on American code for LRFD. Reliability of PSSC girder which is designed based on allowable stress of bridge design code is high for flexural strength.

This study aimed to develop a Structural Health Monitoring System for steel beams in the manner of suggesting and verifying a theoretical formula for displacement estimation using strain gauges, and estimating the loading points and magnitude. According to the results of this study, it was found that when a load of 160kN (56% of the yield load) was applied, the error rate of the deflection obtained with a strain gauge at the point of maximum deflection compared to the deflection measured with a displacement meter was within 2%, and that the estimates of the magnitude and points of load application also showed the error rate of not more than 1%. This suggests that the displacement and load of steel beams can be measured with strain gauges and further, it will enable more cost-effective sensor designing without displacement meter or load cell. The Structural Health Monitoring System program implemented in Lab VIEW gave graded warnings whenever the measured data exceeds the specified range (strength limit state, serviceability limit state, yield strain), and both the serviceability limit state and strength limit state could be simultaneously monitored with strain gauge alone.

본 연구에서는 기존의 분석합성형 분류체계(BC2)로부터 개념과 관계를 추출하여 작성한 자모순 시소러스에 패싯도구를 삽입하여 용어의 개념과 관계를 정확하게 이해할 수 있도록 제시하는데 그 목적이 있다. 그리고, 이러한 과정을 통해 기존의 분류체계나 시소러스가 지니고 있는 한계를 개선하고자 한다.

우리의 생활공간에서 실내공기, 소음, 전자파 등 생활공해로 인한 피해는 시시각각으로 일어나고 있다. 그 동안 깨끗하고 쾌적한 실내환경과 정온한 생활환경 속에서 모든 국민이 건강하게 생활할 수 있도록 다양한 생활환경관리 정책을 추진해 왔다. 하지만, 정부의 노력만으로는 한계가 있다. 국민이 편안한 생활환경의 창출을 위해서는 그 구성원의 자발적인 노력과 참여가 필요하다.

백내장은 수정체가 흐려져 빛을 투과시키지 못하면서 시력장애를 일으키는 질환이며, 더욱이 뚜렷한 예방책도 없다. 따라서 백내장은 가능한 한 발병 초기에 발견하는 것이 중요하다. 적절한 시기에 수술을 받아야 떨어진 시력을 거의 회복할 수 있게 되기 때문이다. 하지만, 약물요법은 이미 진행된 백내장을 원래 상태로 회복시키지 못하고, 단지 진행을 더디게 하는 일종의 보조요법이라는 한계가 있다. 따라서 백내장을 확실히 극복하기 위해선 수술을 받아야 한다.
