A special steels have been developed for the possible applications of turbine blade in nuclear power plant. The compositions of developed alloy were selected by the reference of imported alloy. The various properties such as tensile property, impact energy, hardness, and microstructures were investigated. All the properties of optimum heat treated materials were satisfied with the present specifications of turbine blade materials in unclear power plant. Furthermore, FATT(Fracture appearance transition temperature), high temperature tensile properties, and transformation temperatures of developed alloy also have been studied.

The study has analyzed the determinants of retail rents for the franchised coffee shop with the Multi-Regression analysis in Seoul. Central place, agglomeration, and demand-externality theories provide the basis for empirical models. The data used in this study consisted of 2,000 retail units in Seoul. As the results, the results show that coffee shop of retail sales per $3.3m^2$ and characteristic of retail trade-areas, and characteristic of coffee shop affects on the coffee shop's rents per $3.3m^2$. Coffee Shop's sales are the major determinant of coffee shop's rents. Also, coffee shop's goodwill per $3.3m^2$ and rental bond per $3.3m^2$ are positively correlated with a coffee shop's rents. Additionally, number of wholesale company and manufacturers in the retail trade-areas influences coffee shop's rent per $3.3m^2$. In summary, the study shows that coffee shop's brand identity, location and retail mix in the retail trade areas affects a coffee shop's rent per $3.3m^2$.

In this paper, we study a sample design for survey on goodwill in retail properties to provide a protecting policy for small traders and tenants, to use basic data for a dispute case related to goodwill. Since goodwill in retail properties is occurred by individual rent company, we use the census on establishments from the Statistics Korea as population. First of all, we consider preferentially seven metropolitan cities in which there are more than half of population. Total sample size is decided as 8,000. We allocate the sample size for markets as stratum in each city using proportional formula and the sample size for industrial classifications in each market using root proportional formula. Also we compute survey weights and calculate estimators, standard errors and interval of estimators for each characteristic such as type of establishments and market in seven metropolitan cities.

And housing location was a highly influential factor. Besides, female elderly house-owners and male elderly renters living alone were likely to have higher housing cost burden. And if elderly renters households suffer more financial burden, they had have higher housing cost burden.

The purpose of this study was to explore housing value clusters of young renters in South Korea and their relationships to household and housing characteristics reflected in the 2012 Korea Housing Survey (KHS). The 2012 KHS microdata was used as secondary data. Among the households included in the microdata, 1,196,144 young renter households (between 20 and 34 years of age) in private rental units were analyzed. The main findings are as follows. Ten rating scale items measured housing values. Eight of them were grouped into three value factors: Investment, Affordability and Cost Increase. Using these three value factors and perception of homeownership, households were classified into four clusters: Prospective Home Investor, Settled Renter, Homeowner Wannabe, and Support Needed. The current tenure types, income and expectation for next tenure types of four housing value clusters of young renters reflected Korea's tenure ladder which has home ownership at top followed by Jeon-se rental, monthly rental with deposit and monthly rental without deposit. The households in Prospective Home Investor and Homeowner Wannabe clusters would consider home purchase in the near future. Finally, households in Support Needed Cluster would be the main target to consider in development and implementation of housing welfare policies and programs to resolve housing problems of young renters, including beginning-stage professionals.

As the number of family living alone is expected to soar due to a change in socio-demographics like divorce, more middle-aged women returning to work, homes become smaller and so on. In addition to in 2020 these people will be increase so that 85 percent of the Koreans compose elderly living alone who is over 65. This study aims at developing a sharing-typed elderly people-centered rental model which is accessible in the community integration dimension as an alternative and finding out theirconscious, their need about residence. and we need to check about their major requirements on improvement step by step. so that we suggest the desirable way on the existing multi house. The model provides benefits in the social, economical and pragmatic dimensions as the families living alone get together and living with others, Particularly, as a residence model which reduces a psychological loneliness and at the same time enables the elderly to continue to live a life in the community while they live together with other people, this model could be a strategy which supports the "Aging in Place." This study is in progress via small group workshop which debate gradually about special subject with similar group member. So we can find the residence's preference on living environment in various condition and the member can imagine freely on their future living arrangement by giving the various informations which can be proceed in future. The workshop proceed three times. at the first workshop, we're check their living environment and satisfaction level. and second time we give the knowledge about shared-type rental house then discuss about the model. and last time we're listen to the residence's opinion.

This study explored housing situation and expectations of young (age between 20 and 34 years) single-person Jeon-se renters and monthly renters with deposit in relation with their family support and own housing cost burden status. Major findings from the analysis of 1,695,729 households were as follows: (1) Among subjects, 27.4% received family supports to pay their rent deposit, and 39.4% had more 'own housing cost burdens' to have housing costs minus the amount supported by their family be 30% or more of their income. (2) More than 11% were found to be 'more burdened' despite receipt of family supports. (3) Family support status was found to be related to formation of first-time households and tenure changes, while own housing cost burden was found to be related to current housing situation and previous and next housing size changes. (4) Households received family supports showed a greater proportion of first-time households or households experienced tenure upgrades. (5) 'Less burdened' households tended to expect housing size upgrade in their next move more positively. Based on the study findings, it was suggested to extend supply of rental housing and housing subsidy targeting young renters in conjunction with programs to encourage their savings.
