This study examined the effect of housing cost burden on the intention of moving into public rental housing. For the empirical analysis, I used the 2019 Korea Housing Survey and divided the households based on housing tenure and income level and they are as follows: homeowners, renters and low income, middle income and above. As analysis method, the binomial logit model is used and the empirical analysis shows that the burden of housing costs was increased the intention of moving into public rental housing even in homeowners and households with middle income or higher.

단독주택을 8-10가구의 다세대 주택으로 용도를 바꾸는 '지분 쪼개기' 때문에 최근 서울을 비롯한 수도권 곳곳에서 다세대 주택 신축 붐이 일고 있다. 서울시가 무분별한 지분 쪼개기를 막기 위해 가구당 전용 면적 $60m^2$ 미만 주택은 입주권을 주지 않고 돈으로 청산하는 방식으로 규제하겠다는 방침을 밝혔지만, 현장에서는 다세대나 빌라 신축 공사가 더욱 활발하게 진행되고 있다. 게다가 조례를 개정하는 7월 전까지 건축 허가를 받으면 면적에 상관없이 입주권을 받을 수 있다는 점을 노린 막판 투기가 기승을 부리고 있어 논란이 일고 있다.

The aim of this study is to investigate and to analyze the reverberation times of apartment houses Measurements were conducted in a total of 44 rooms(36 rooms were in occupied houses and 8 rooms were in unoccupied houses) according to KS F 2864. The results showed that the averaged reverberation time of the occupied and the unoccupied houses were about 0.3$\sim$0.5sec and 1.2$\sim$l.5 sec, respectively, at 500Hz octave band frequency. And the averaged absorbtion coefficient of the occupied and the unoccupied houses were about 0.13$\sim$0.35 and 0.11$\sim$0.20, respectively. In addition, We verified that the reverberation time generally depended on the frequency; the lower the frequency, the higher the reverberation time.

지난해12월 정부에서 '발코니 개조 = 불법' 이라는 자물쇠를 풀고 합법화를 선언했다. 하지만 새 아파트에 입주하기 전에 발코니를 개조할 경우 취득세와 등록세를 부과하는 등 각종 부담이 더욱 가중될 전망이다. 발코니 개조 합법화, 이에 뒤따르는 세금 부담과 의무 조항에 대하여.

The test and evaluation of floor impact sound is mainly conducted before move in the residence. Floor impact sound generating is actually the conditions in which a heavy load like a curtain and furniture is installed, the situation before and after move in the residence is different. In this study, we investigate the floor impact sound variations according to the live load installation like furniture in the source room. The vibration acceleration level and floor impact sound level variation were measured before and after live load ($200kg/m^2$) installation in the floor impact sound test building and the field. The difference was not large although the vibration acceleration level and the floor impact sound level were reduced through measurement result of load installation. Resonance frequency was not changed by load installation.

This study aims to present the fundamental strategies for improving the Indoor Air Quality(IAQ) in newly-constructed apartment buildings. To investigate the concentration of indoor air pollutants such as HCHO and VOCs and the field measurement were conducted. According to the field measurement of 60 new houses in spring season, the concentration of HCHO in about 20% were higher the IAQ standards.

Infiltration is air flow that occurs through cracks in buildings. According to level and kind of infiltration, the cooling load and heating load in buildings may increase. In this study I conducted field measurements to evaluate air tightness in 27 new apartment units. Field measurements for new apartments was the focus. For the de-pressurization method, the equipment utilized to gauge airtightness included KNS-5000C and KNS-4000 which were installed on the window in order to measure indoor air leakage. The results are summarized as follows. The average ACH50 of a $59m^2$ APT was 3.98, 3.82 for a $84m^2$ APT, and 2.73 for a $114m^2$ APT. The total average ACH50 of 27units was 3.51.

This aims to study impact of the youth start-up business incubating system by government's or local autonomous governments' center on start-up business performance. This focus on Youth Start-Up Business Support Program operated by Seoul Metropolitan City and explore practical alternatives. In this study, young entrepreneurs are defined as those who are aged between 20 and 40, and start-up is defined as an act by such entrepreneur that establishes an organization or system that produces any goods or services selected as business idea by utilizing capital in order to create profits. The empirical results are as follow; a significant correlation between scale of capital in initial stage by young entrepreneur graduating from Start-Up Business Support Center and start-up success satisfaction by young entrepreneurs. There is a significant correlation between the number of obtained intellectual properties before moving into Start-Up Business Support Center and start-up success satisfaction by young entrepreneurs. There is a significant correlation between the degree of satisfaction on start-up activity support fund for young entrepreneur in Start-Up Business Support Center and start-up success satisfaction by young entrepreneurs. There is a significant correlation between the degree of satisfaction on promotion and territorial cultivation support activities for young entrepreneur in Start-Up Business Support Center and start-up success satisfaction by young entrepreneurs. There is a significant correlation between the degree of satisfaction on collaboration support among member firms for young entrepreneur in Start-Up Business Support Center and start-up success satisfaction by young entrepreneurs. There is a significant correlation between the degree of overall satisfaction on start-up business support program for young entrepreneur in Start-Up Business Support Center and start-up success satisfaction by young entrepreneurs. The study has an implication that it provides a basic data on policy support strategies by central and local autonomous governments that facilitate young entrepreneurs to achieve start-up business goals by understanding the factors that affect the business performance of young entrepreneurs. In addition, the study offers an effective direction for young entrepreneurs in a way that promotes the start-up performance by young entrepreneurs, which expects to contribute to core factors of new employment opportunity creation as well as national and local economies, so that the author expects the study to play a role of raising the necessity of start-up business support for young entrepreneurs.

400RT geothermal system which is the biggest capacity among on-operations at present in Korea is measured and evaluated on 23rd${\sim}$26th Jan. 2008 during those days building is not allowed owners and/or tenants to move in. The geothermal system is consist with vertical-typed 112 geothermal heat exchangers which are installed circle-like 1 row with 4m interval, and has 16 units of 25USRT geothermal-source heat pump(GSHP)s. And each 5 units of circulation pump are running for geothermal heat exchangers and hot water supplies. The followings are the results. The temperatures at G.L. -70m of 2 boreholes are varied quite similarly. The average temperature difference between inlet and outlet of geothermal pipes is $4.1^{\circ}C$, and that of hot water supply is $3.2^{\circ}C$, of Zone 3's each 4 GSHPs when being operated. Despite temperature fluctuations by heating loads, the average temperature difference between main pipes of inlet and outlet of geothermal heat exchangers is measured as $4.1^{\circ}C$. This study propose "Geothermal System COP" which includes not only consumed electric power by compressor but also circulation pumps and auxiliary utilities. By comparing the geothermal system COP with GSHP's performance specification, it is clear that the performances of GHSPs of this site are satisfied with the specification.
