인터넷이 일반에게 보급된지도 이제 10년이 넘었으며, 우리나라의 인터넷 보급율은 25%로 미국, 캐나다보다는 낮으나 영국, 일본 보다 높으며 인터넷 인구는 매월 10%이상 성장하고 있는 것으로 나타났다. 이러한 상황에서 인터넷을 통한 전자상거래 시장도 급속도로 성장하고 있으며, 기존의 재래시장의 구매층이 빠른 속도로 인터넷 전자상거래 시장으로 이동하고 있음을 알 수 있다. (중략)

As a result of the 2010 census, the most severe change appears household structure changes and single-person households's constantly increasing. As a result, the following changes in the housing market are to be expected. First, the changes to the center of the two-person households in four-person households would be reorganized into the small and medium-sized apartment in the center of mid-range and high-end apartments. Second, on the continued increase in the proportion of one-person households, the sustained growth of the rental market is expected. Third, on the continued increase in the proportion of one-person households, one-room house, office buildings, and residential urban life set to meet the needs of consumers, a variety of rental market boom times will come.

This study is to furnish basic data for establishing the improvement counterplan of Housing environment and to solve the problem of Housing supply resulting from the continuous increase of population and to examine the historical flowing, the present condition and problems of Housing in Uijeongbu city. Including of the multi-house to the number of Housing, the supply ratio of Housing is 95% in quantity of the Housing in Uijeongbu city in 2004. Now, it is important time in the respect of quality as well as the quantity in supply matter of Housing. In fact, the main viewpoint in housing supply policy has been brought focus into the economic profits more than public interests. As a result of that, the residence environment has been worse. From now on, a Local autonomous entity including the construction authorities and Uijeongbu city authorities must focus on the public interests in solving problems of Housing.

현재 우리나라는 인구의 도시집중과 주거용 건물의 부족으로 인하여 발생하는 주택부족문제는 현대산업사회에서 피할 수 없는 현상이 되고 있고, 1970년대 들어 대도시로의 인구집중과 함께 극심한 주택난을 겪게 되었다. 전국의 주택보급률은 국토교통부가 발간한 '2014년 국토교통통계연보'에 따르면103%(서울 97.5%, 경기 98.7%)에 이르러 주택의 공급측면에서 큰 문제가 없어 보이지만, 2014년 전국 자가 주택 거주율은 53.6%로 절반 정도의 가구가 타인 소유의 주택에서 임차인으로 거주하고 있다. 이와 관련하여 가장 큰 법률문제 중의 하나는 임차주택에서 임차인이 그 가족들과 모두 함께 안정된 생활을 하는 것이라고 볼 수 있는데 만약 임차인이 사망한 경우에 그동안 임차인과 함께 생활 해온 가족들이 종전과 마찬가지로 당해주택에서 주거를 계속할 수 있는가 하는 문제이다. 이에 대해 주택임대차보호법은 임차주택에서 가정공동생활을 하고 있는 자에게 임차인의 권리 및 의무를 승계하도록 인정하고 있다. 그러나 사망임차인과 동거해온 상속인이 아닌 사실상 혼인관계에 있는 자에 대해 상속인이 아니라는 이유로 선순위상속인이 당해주택의 명도를 청구할 수 있다면 이것은 사망임차인과 동거해온 가족으로서 심각한 사회적인 문제가 된다. 따라서 본 논문에서는 주택임대차보호법상 임차권승계와 관련하여 제기되고 있는 문제점을 검토하고 그에 대한 개선방안을 제시하고자 한다.

태양광 주택 보급을 위해서는 기존에 고가의 실리콘 기판을 이용한 고효율 달성을 위한 연구중심의 태양전지 개발연구가 주축을 이루어왔다. 이는 개발에 성공하더라도 고가, 고난도, 복잡한 다단계 공정기술을 이용하는 단점 때문에 보급활성화를 촉진하기 위해서는 저가의 다결정 실리콘 기판을 이용한 중 상급 태양전지 상용화 기술개발로 전환할 필요로 인하여 본 연구에서는 차세대전력용 태양광발전시스템의 요소소자인 다결정태양전지 고효율화의 열쇠가 되는 기술력 확보를 통한 저가, 대면적, 고효율, 고수율 제품 대량생산 상용화에 중점을 두었다.

This study analyzes the economies of photovoltaic systems in an apartment complex of 1,185 households, in cases of feed-in tariff and subsidy for solar home program of the government. When including the revenue only from electricity sales, NPVs of subsidy and that of feed-in tariff are -560 million KRW and -87 million KRW respectively. With the avoided social cost included without the revenues from CERs, NPVs of subsidy and feed-in tariff are -556 million KRW and -84 million KRW respectively. With the revenues from CERs, NPV of subsidy is -526 million KRW and NPV of feed-in tariff is -54 million KRW. As results of sensitivity analysis based on the changes in capital costs and discount rates, while all scenarios with subsidy including the revenues from CERs are not commercially viable, all scenarios with feed-in tariff exclusive of the revenues from CERs are commercially viable when discount rate is less than 7.2% or capital cost is less than 6,840 thousand KRW/kW. In the cases that include the avoided social cost, while all scenarios with subsidy including the avoided social cost as well as the revenues from CERs are not commercially viable, all scenarios with feed-in tariff are commercially viable without the revenues from CERs when discount rate is less than 7.2% or capital cost is less than 6,856 thousand KRW/KW. The results indicate that the changes in discount rates do not influence the revenues from CERs, but the revenues from electricity sale. Considering that the number of apartment complex and the positive environmental and social benefits from PV system, government needs to promote its diffusion.

Rapidly increasing automobile supply rate according to improved economic level of life makes lack of parking space of apartments. Even though the initial design of parking space compiled with old regulations, it may not observe either new laws or requirement of inhabitants. Even if old apartments have no structural durability problem, outworn facilities and insufficient parking area may be a main reason for reconstruction. It causes waste of national resources and makes recycling issues. Additionally, irregularly parked cars make traffic obstruction to a fire engine and result in many fire accident victims. Parking problems of apartments are not only inconvenience but also serious safety issues. From these points of view, remodeling only for parking area expansion is necessary to avoid overall reconstruction of apartments. The purpose of this study is to suggest a retaining wall selection method for apartments underground parking lots expansion without evacuation of resident people. Effect factors to select retaining wall system are analyzed and weight values are calculated by applying AHP. One selection method of retaining wall is proposed by evaluating applicability and its sensitivity analysis is executed. This selection method is expected to help decision-making of retaining wall system selection.

As an exploratory research to understand the nature of relationships between ports and their neighboring communities, this study analyzes how ports influence their residents' quality of life(QOL). The QOL was measured by 17 indicators reconstructed by reviewing relevant literatures. As a result, both Busan port and Dalian port were found to have statistically significant influence on many of QOL indicators including general expenditure per capita, number of manufacturing factories per capita, number of factories's laborer per capita, the rate of pavement, number of traffic accident per capita, rate of housing supply, number of financial agencies per capita, park area per capita, number of cultural assets per capita, the size of welfare expenditure per capita, number of fire occurrence per capita. And Busan port have statistically significant influence on QOL indicators including the rate of increase in population, number of public health industries per capita, number of public health industries per capita, number of schools per capita, number of sick-beds per capita, but Dalian port not have influence. Also Dalian port have statistically significant influence on number of crime occurrence per capita, but Busan port not have influence.

In this paper, we proposed a thickness measurement method of concrete slab using GPR, and the verification of the suggested algorithm was carried out through real-scale experiment. The thickness measurement algorithm developed in this study is to set the relative dielectric constant based on the unique shape of parabola, and time series data can be converted to thickness information. GPR scanning were conducted in four types of slab structure for noise reduction, including finishing mortar, autoclaved lightweight concrete, and noise damping layer. The thickness obtained by GPR was compared with Boring data, and the average error was 1.95 mm. In order to investigate the effect of finishing materials on the slab, additional three types of finishing materials were placed, and the following average error was 1.70 mm. In addition, sampling interval from device, the effect of radius on the shape of parabola, and Boring error were comprehensively discussed. Based on the experimental verification, GPR scanning and the suggested algorithm have a great potential that they can be applied to the thickness measurement of finishing mortar from concrete slab with high accuracy.
