Permanent rental housing, the construction of which was strongly financed by the central government, is regarded as a social housing for those who fall within the lowest income bracket. Differing from "public rental housing", offered to tenants for sale after a five year rental period, this type of housing is intended for rental use on a long-tenn basis. At present, about 190,000 permanent rental housing units exist in Korea. According to a statistics, 15.6% of its residents did not pay their management fee and rental payment in 4 or more months in 2005, which places stress on the housing management. Based on the "eviction condition" stipulated in the tenancy agreement for permanent rental housing, a householder owning assets or a vehicle which is not used as his means of living, who is overdue with his management fee and rental payment for a long time, may be evicted from the house. However, there are many conflicts and problems between administrators/housing managers and residents in the process of enforcing this regulation. The purpose of this study is to explore the key issues associated with the present situation and the reasons why so many management fee and rental payment for permanent rental housing are overdue. For the purpose of research, data were collected from 10,990 permanent rental housing residents nationwide via a questionnaire survey in February 2007. One third of the respondents had an experience of more than 2 months overdue since they have moved in current residence. For further analysis, the respondents were divided into three groups, based on their working ability. The major finding showed that the group of respondents who have working ability required a more practical plan, such as employment, to have a sustainable life, while the other group of no labor force indicated a need for more housing allowance from the government. To suggest more specific alternatives for the subject of housing payment overdue, further comparison study should be performed between the residents of permanent rental housing and other low income tenants in private housing sector.

Friedensreich Hundertwasser , born in Vienna 1928, is a painter, an architect and an environmentalist. His architecture is radically different from the traditional , straight -lined, functional architecture practised, for example, by the Bauhaus Masters. From the very beginning , he has tried by various means to show that radical change in thinking are necessary , possible and realized. Hundertwasser's goal in this architecture is to make and give human dwelling in harmony with nature. his architecture is characterized by avoidance of straight lines, " Window Right", irregular arrangement of windows, onion dom, a wealth of colours and such environmentally -friendly consideration as planting of roofs and realizing of "tree-tenants". hundertwasser sees houses as evolving creations which are to be shaped by their inhabitants. He hates Uniformity. The irregularity is always the guiding principle in his architecture. The Hundertwasser's architeucture express his fundamental belief that we may not simply rob nature of her resources, but that we must also return territory to nature which we habe stolen from her. Roofs, terraces and courtyards planted with vegetation and " tree-tenants" build bridges between man and nature. They influse the architecture with vitality and romanticism and are a statement of a quality rather than a standard of living. It is quite possible to value the architecture of Hundertwasser as an important inspiration, as a sort of turning point in the thoughts and actions of city planners. It's success could be healing shock for the international architectural community, which is hypnotized by technology and abused by the shortsighted interests of ren.tability . Under this pressure, today's architects trend to reduce people to a mere part of the " Dwelling machine", without acknowledging that in the long run such machines eat away at people's souls.uch machines eat away at people's souls.

본 연구에서는 최근 기관투자가의 투자대상으로서 그 중요성이 커지고 있는 국내 오피스에 대해서 해외 선행연구에서 유의하게 입증된 여러 스타일인자의 유의성을 검정하였다. 검정대상이 된 설명변수에는 지역, 규모(평가금액), 가치성장성(소득자본수익격차), 임대차조건(임차인수, 평균임대차기간, 핵심임차인비중) 등이 포함되었다. 분석자료는 감정평가에 기반한 국토교통부 임대사례조사 DB 중 일부를 이용하였다. 분석결과 다음과 같은 시사점을 얻을 수 있었다. 우리나라 오피스시장의 경우 스타일인자로서 지역은 여전히 중요한 의미를 가지며, 이와 함께 규모도 유의하게 작용하였다. 단 핵심지역의 대형자산일수록 위험과 수익이 높게 나타나 일반적인 믿음과 차이가 있었는데, 이는 분석기간 동안 서울 3대권역의 대형오피스 가격이 급등했기 때문인 것으로 생각된다. 이러한 현상은 미국의 선행연구에서도 발견되고 있어 지역과 규모의 역할에 대해 신중한 접근이 필요함을 알 수 있었다. 가치성장성의 경우 가치성이 클수록 예상한대로 위험과 수익을 낮추는 것으로 나타나 국내에서도 유의한 스타일인자임이 확인되었다. 임대차조건과 관련해서는 임차인수 만이 유의하게 나타났는데, 이 역시 예상대로 임차인 분산이 잘 이루어질수록 위험과 수익이 낮은 것을 알 수 있었다.

The rapid development of cloud computing and high requirements of operators requires strong support from the underlying Data Center Networks. Therefore, the effectiveness of using resources in the data center networks becomes a point of concern for operators and material for research. In this paper, we discuss the online virtual-cluster provision problem for multiple tenants with an aim to decide when and where the virtual cluster should be placed in a data center network. Our objective is maximizing the total revenue for the data center networks under the constraints. In order to solve this problem, this paper divides it into two parts: online multi-tenancy scheduling and virtual cluster placement. The first part aims to determine the scheduling orders for the multiple tenants, and the second part aims to determine the locations of virtual machines. We first approach the problem by using the variational inequality model and discuss the existence of the optimal solution. After that, we prove that provisioning virtual clusters for a multi-tenant data center network that maximizes revenue is NP-hard. Due to the complexity of this problem, an efficient heuristic algorithm OMS (Online Multi-tenancy Scheduling) is proposed to solve the online multi-tenancy scheduling problem. We further explore the virtual cluster placement problem based on the OMS and propose a novel algorithm during the virtual machine placement. We evaluate our algorithms through a series of simulations, and the simulations results demonstrate that OMS can significantly increase the efficiency and total revenue for the data centers.

This paper considers the problem of scheduling loading and unloading operations of a crane in a railway terminal motivated from rail-road container transshipment operations at Uiwang Inland Container Depot (ICD). Unlike previous studies only considering the total handling time of containers, this paper considers a bi-criteria objective of minimizing the weighted sum of the total handling time and tenant service time. The tenant service time is an important criterion in terms of terminal tenants who are private logistics companies in charge of moving containers from/to the terminal using their trucks. In the rail-road container shipment yard, the tenant service time of a tenant can be defined by a time difference between beginning and finishing loading and unloading operations of a crane. Thus, finding a set of sequences and time of the crane operations becomes a crucial decision issue in the problem. The problem is formulated as a nonlinear program which is improved by linearizing a nonlinear constraint in the model. This paper develops a genetic algorithm to solve the problem and performs a case study on the Uiwang ICD terminal. Computational experiment results show that the genetic algorithm shows better performance than commercial optimization solvers. Operational implications in terms of tenants are drawn through sensitivity analyses.

The concept of sharing economy has received rich attention in recent years. As a typical type of business model in the sharing economy, online short rent has been paid attention by both industry and academia. In this study, we find trust to be a critical determinant to the success of online short rent platforms. Based on three dimensions of trust theory, i.e., ability, benevolence and integrity, we investigate the factors influencing tenant' willingness to participate in online short rent. We further examine the extent to which trust can influence the number of sales and comments of rooms listed at online short-term rent platforms, which can represent tenant' willingness to participate in the sharing economy. The results show that the trust dimensions represented by a landlord's personal characteristics have significant positive correlations with the number of sales and comments. For example, the real name authentication and the sesame score can represent the trust integrity; online replay ratio and the average confirmation time representing the trust sincerity, and the order acceptance ratio representing the trust ability. On this basis, we proposed some recommendations for both platforms and landlords. For example, the landlords can improve the tenants' trust by authenticating his/her real name, replying actively and timely. For platforms, when they make housing list ranking rules, they can take the landlord's personal attributes that may affect trust into consideration. Moreover, platforms can also allow landlords to supply value-added services to improve service quality and ultimately promote the virtuous circle of the platform ecosphere. Through conducting the empirical research on a particular application of the sharing economy, we aim to fill the research gap of this field in China and provide theoretical and practical contributions to the future development of online short rent.

본 논문의 목적은 다른 나라에서는 찾아보기 어려운 재개발사업 구역내 세입자를 위한 임대주택공급제도가 1989년에 도입될 수 있었던 상황을 분석해보고, 실제로 제도가 어떻게 작동했는지를 살펴보는 것에 목적이 있다. 제도 도입 상황으로는 첫째 조합과 건설업체가 과도한 이익을 누리는 합동재개발 방식에 대한 비판이 확산되고 있었다는 점, 둘째는 재개발사업으로 주거지를 상실한 세입자들이 공공임대주택을 요구했다는 점, 셋째는 군사정권의 연장으로 보는 시각을 불식시키기 위한 노태우 정부가 투기억제 및 사회적 불평등 해소를 위한 정책도입에 적극적이었다는 점을 들 수 있다. 이러한 상황이 복합적으로 작용한 결과, 재개발조합으로 하여금 재개발사업구역내에 세입자를 위한 임대주택을 일정비율 건설하도록 하고, 정부가 이를 원가로 인수하여 세입자에게 공급하는 재개발임대주택 공급제도가 도입된 것이다. 서울시에서는 1989년 8월부터 재개발임대주택 의무건립제도가 추진되었으나 전국적으로 확산된 것은 2005년 5월 이후부터이다. 의무건립비율은 서울시가 도입했을 당시는 재개발임대주택을 원하는 세입자수만큼 지어야 한다는 다소 애매한 규정이었다. 2005년에는 재개발사업을 통해 공급되는 주택수의 17%, 이후 몇 차례 비율이 낮아졌으나 2020년 현재는 20%로 규정되어 있다. 건립비율은 정권이 보수냐 진보냐에 따라 보수면 하락하고, 진보정권이면 올라간 것으로 나타난다. 재개발임대주택의 규모는 40m² 미만의 소형이 압도적이지만 2010년 이후에는 60m²에 가까운 주택도 공급되었다. 임대료는 시세에 비해 대단히 저렴하다. 입주자의 이주나 사망 등으로 공가가 된 재개발임대주택은 일반 저소득층에게 공급되는데 2020년 입주경쟁률은 9:1에 달할 정도로 높았다.

This study performed GIS and statistical analyses on the location and spatial characteristics of the slum in Daejeon. Spatial data of 648 slum residents in Daejeon were collected and 131 residents among them were surveyed. The results showed the trends of higher rent, lower social exclusion and closer neighboring relations in slum center than the surrounding areas, which could be interpreted as the interrelated multilateral effects of the micro- (housing), meso- (relations), exo- (community) and macro- (government policy) systems. The strong bonds among neighbors and various supports from social service facilities elevated the slum area's rent and diminished residents' social exclusion more than housing conditions (for instance, poor hygiene and low safety). Slum tenants willingly paid a premium for their substandard housings and refused moving to governmentally provided modern housing units. In urban development, administrative authorities need to be cautious about slum uprooting. Much rather an alternative renewal approach is needed which protects the slum's intimate relations while improving its overall living standards.

SaaS provides software hosted on the cloud computing in a form of service. Thus, it enables the extension of service functions by combining or reusing the existing software. As an analysis technique, this paper suggests a method of verifying the reusability of a process by analyzing it with the process algebra. The suggested method can confirm the reusability of existing software, ensure the consistency of modifications by tenants or requests, and provide probabilities of combining processes.

According to office building design in Korea, building exterior and office automatic systems through introducing IB system have been improved. However, the lower floors of a building are functionally easy to transfer but actually functions as an enterance. Although at takes a large investment by the owner or enterprise, mainly the tenants and neighbors are in a broad sense the actual users. In this point of view, the lobby of an office bulidling which is the connection between the exterior as a public space and the interior as a private area, does not only have the function of an enterance but also has to be an image of the enterprise or the building itself. Therefor the lobby must contain various functions of space.
