In the domestic housing market, uncompleted lot-solid apartments and unoccupied residences are increasing in the medium-large scale area whose rents and transactions have been unstable, as going through the financial crisis and economical recession. Demands for small-scale housings are steadily increasing by practical consumer group who don't need large places, which are often not needed for the current people who are spending most of their time outside of their houses. Therefore, this study proposes the useful methods for spatial planning for small-scale houses for multiple households, including variable form, levels form, multi-level form, and smart-sizing. For efficient spatial planning for that purpose, here, small-scale housings are not limited to places for families with 1-2 members, but considered as one of broader approaches to graft various households and families. In addition, we examined the existed trends of researches about spatial utility of small-scale places, and did the research about the status of small-scale housing developments, and then proposed the direction for future small-scale housings by analyzing the advanced examples.

The computational flow analysis using LES technique was carried out to investigate the flow characteristics of a sirocco fan under the maximum flowrate condition. The commercial SC/Tetra software was used for this unsteady and three-dimensional numerical analysis. In consequence, because a flow is unstable within the range of about 50% of a housing depth from a bellmouth around the cutoff region, the passing flow through the blade cascade occurred on the X-Y plane is a slow or a reverse with approaching to the housing inlet. Also, the secondary flow shows on the radial plane of a housing, and its vortex center exists within about 33% of a housing depth from a bellmouth except the cutoff region. Moreover, the flow occurring on the exit plane of a sirocco fan shows a complex secondary flow.

The Korean Government has provided public rental housing to stabilize civilian dwelling. However, unreliable management of public rental housing threatens the stability of residency. This study analyzes the default of public rental housing and the cause of default through a case study, which was intended for the residents in apartment complexes in danger of default. It also suggests countermeasures to cope with the problem of public rental housing. The results are listed as follows. First, rental housing apartments contribute a lot to the housing stability policy. On the other hand, the default of housing development, which is derived from the bankruptcy of housing management companies and the negligent control of government, brings about a serious problem for housing stability. Second, although the government has made a steady effort to solve this default problem, 9000 residents from 8 apartment complexes in Korea have experienced extreme unstable residency. Third, there are many causes for the default of public rental housing such as unqualified management companies and cursory monitoring by the government. The fundamental solution is to prevent public rental housing management companies from managing, or to build a new management system of public rental housing. To solve this problem, it's recommendable to delete the application term in the special law on the default of public rental housing so that it can be applied to all default apartments. If it is not possible to perform the policy for financial reasons, a new supply of civil housing provided by private companies needs to be re-examined completely or banned.

This paper provides the result of analysis of the structure and I-V characteristics of D.C. 1500 V surge arresters which were installed in railway line currently. As Porcelain housed surge arresters have unstable elements such as exploding and dispersion, so it is thought that the system is protected more stably with replacement of polymer housing. The adoption of gap mitigates the voltage stress which is degradation factor of surge arresters and the research is needed to enhance the life characteristic in additive and manufacturing process. Therefore, it is thought that the research should be continued to develop homemade the surge arresters for D.C. railway line as well as transmission line.

In Korea, the rental apartments for low-income bracket have greatly been built and are being built now. But their management system is quite unstable and the residents' participation in the management is excluded throughly from the beginning. As a result, there are increasing complaints about their low quality of management as well as a self-righteous managerial behavior by the housing company. Therefore, it is required to be managed by residents in the rental apartmenr and especially the organization of management, such as decision making-executing-audition body, should be operated by the residents. To achieve this purpose, the management law should be consolidated into one and the method o imposing the expenses of repairing and maintenance should be improved by The Ministry of Construction and Transportation.

The purpose of this study is to examine the features of children poverty in Korea. Using the 7th Korean Welfare Panel Study, this study conducts latent class analysis to classify households with children. Results show that households with children are classified into three types: 1) housing expenditure overburdened households, 2) multidimensional deprivation households, 3) non-poverty households. The housing expenditure overburdened households have higher rates of housing expenditures than the other two groups. The multidimensional deprivation households experience various types of deprivation such as food insecurity, poor housing, and unstable job security for householders. The results imply that comprehensive approaches are needed to address multiple problems which poor households with children suffer.

the quality of a TV is closely connected with the high quality surface of Braun tube. To get high quality surface an improved grinding system is needed. It has three main parts : the housing part of supporting frame the outershaft part rotat-ed by motor and the innershaft part having eccentricity from the rotation axis of the outershaft. the housing part and the outershaft part are connected by outerbearings, The outershaft part and the innershaft part are connected by innerbearings. Although the outershaft part is rotated at high-speed the innershaft part is not rotated by offset coupling. The high quality grinding surface can be obtained by this mechanism of panel surface grinder, Because the innershaft is unbalanced by eccentricity from rotation axis of outershaft the unbalancing vibration is resulted In this rotor system with high-speed rota-tion the unbalancing vibration makes the opertion unstable. In this research the transfer function is obtained bythe frequency response analysis of finite element model. The simu-lation result is proved by comparing with the experimental result measured by signal analyzer Then the results are corre-lated. in order to improve the design an optimization method is used instead of two-planes balancing method The parts of the 3-dimensional panel surface grinder satisfy the each constraint, The result shows that the design of the panel surface grinder can be optimized.

As the government announced Real Estate Policies on August 02, most areas except for Seoul cities face increasing business risks. Moreover, the government control over financial sectors' loan leads to the highly possible contraction of new distribution markets. The market trend could bring about the reduction of new demand in PF (Private Financing) business that large construction companies mainly concentrate on, and even the business already obtained has a high risk of being distributed, which could result in substantially low profitability. The currently unstable financial structure of most construction companies is caused by the hike of the prime cost of foreign plants except for that of a few construction companies. If PF (Private Financing) business also faces a difficult situation in such a financial condition, even large construction companies come to have the high possibility of a deficiency in credit rating. Accordingly, the major business that large construction companies concentrate on needs the sufficient business review. It is desirable to make a bid for business guaranteeing stability rather than business solely in consideration of profitability, when participating in a competition for a new construction contract.

The purpose of this study is to analyze the present condition of work-leisure balance and its influencing factors in employed young single households. Three groups of sample households-work-oriented, balanced, and leisure-oriented-were compared by factors related to work and leisure. Six cases were interviewed to obtain qualitative data on the subjective meaning of work-life balance and its influencing factors. The results showed different characteristics between the three groups based on the various work- and -leisure- related factors: average weekly working hours of the week, number of vacation days per year, weekday leisure time, degree of weekday freedom, and sufficiency of the leisure cost. In addition, the characteristics considered desirable for quality of life differed between groups. Finding the meaning of life through work and leisure was very important for those respondents, who have an unstable position in the labor market, and who want to delay making decisions on moving into the marriage and family-building phase recognized as a major development task for Korean adults.

The unit modular method is one in which unit modules are prefabricated at a factory and then constructed at a construction site. That is why an important process, transporting unit module, is added in this method. The purpose of this study is to analyse the load for transporting unit module. The results of the analysis of the driving experimental runs revealed that a maximum load of 15 kN was applied on adapter block type A and a maximum load of 25 kN on adapter block type B. These loads were recorded at the points in the road test when the low-bed trailer was driving through unstable sections of the test such as stopping, restarting, passing over a speed bump or taking a left turn at speed.
