An apple wine was prepared by fermentation at $25^{\circ}C$ for 2 weeks using Saccha개myces cerevisiae KCCM 12224, followed by aging at $15^{\circ}C$ for 14 weeks, and its physicochemical and microbiological changes were investigated. The viable bacterial cell numbers, increased from $1.4{\times}10^3\;CFU/ml$ at the beginning of fermentation, to $2.8{\times}10^6\;CFU/ml$ after 2 weeks, but decreased to $1.0{\times}10^5\;CFU/ml$ after aging. The viable yeast cell numbers changed from $4.3{\times}10^4\;CFU/ml$ to $1.2{\times}10^7\;CFU/ml$ during the fermentation, and decreased to $1.2{\times}10^4\;CFU/ml$ after aging. Sugar content changed from $20.0^{\circ}Brix$ to $8.5{\circ}Brix$, and reducing sugar content was changed from 9.66% to 6.44%. Alcohol content and acidity increased to 7.0% and from 0.19% to 0.24%, respectively. No changes in acidity, pH, and sugar content were observed during the aging, but reducing sugar and solid contents decreased. When apple wine was fultered through $0.45\;{\mu}m$ nitrocellulose membrane followed by various ultrafiltration membranes with different molecular weight cut-off values, the initial flux $(121.2\;liter/m^2/h)$ and the average flux of Biomax 100k membrane were the highest among the membranes used. These membrane filtration treatments resulted in complete removal of microorganisms as well as decrease in turbidity and solid content without changes in other chemical properties. No changes in the physicochemical properties of the apple wine and no microorganisms were detected during the storage at $156{\circ}C$ for 6 weeks.

This study conducted a multivariate time series analysis utilizing macroeconomic and regional variables to analyze factors affecting apartment prices in Daejeon. Unit root and cointegration tests were used to confirm long-term relationships between variables, and the VEC model was applied to analyze short- and long-term influences. The analysis revealed that interest rates and the Consumer Price Index significantly impacted apartment prices in the long term, while mortgage loan amounts and the Industrial Production Index, which represents income, were key variables in the short term. This suggests that apartment prices in Daejeon are significantly influenced not only by macroeconomic variables but also by regional economic and credit conditions, highlighting the need for real estate policies that take regional characteristics into account.

1. CONTENTS (1) RESEARCH OBJECTIVES The government amended the Special Measures Law on the compensation of land included in rivers on June 26, 2009, in which the land compensated by the Special Measures Law is defined as a land that falls in river areas of national rivers or the first local class rivers. The nation or local government are trying to actively solve this problem for unpaid river sites that were included in rivers, but have not yet been compensated. However, local rivers other than national rivers confront civil complaints because related compensations have been postponed due to the shortage of finances in local governments. First of all, there are some systematic problems for the land compensation of unpaid river sites even though there are various reasons under this circumstance. Therefore, this study desires to suggest reformations by figuring out compensation systems and for loss of unpaid river sites and their status including existing problems. (2) RESEARCH METHOD The time and spatial scope of this study on the reformation of compensation system for unpaid river sites is from 1971 to the present, and the object of this study is the unpaid river sites that were included in national and local rivers in Korea. For a methodology used in this study, we examined some cases that were compensated for unpaid river sites being compensated focusing on national rivers according to the 'construction project for main 4 rivers,' taking into account some cases compensated thanks to the amendment of the Law of Rivers and suggested a reformation for them. (3) RESEARCH FINDINGS The Law of Rivers in Korea acknowledges only a nation's buy-back right excluding a claim for recapture of unfair profits or 'a claim for damages' under the Civil Law according to the state-owned river system. National rivers are being claimed for purchase according to special laws of the Special Measures Law on the compensation of land included in rivers, but the land compensations for local rivers(including small rivers) are being postponed despite a lot of recent civil complaints because local governments should compensate for them by local finances. While the percentage of rivers managed by the nation is 90%, that of rivers managed by the Korean government is less than 10%. Considering that private lands are being included in local rivers due to natural disasters such as floods in summer in Korea, special measures for compensation of the land included from local and small rivers are required at this point. However, more systematic compensation measures should be taken for local and small rivers at the time when the compensation for national rivers are nearly being completed. 2. RESULTS First, we need a reformation to extend a nation's buy-back right for river sites by upgrading local rivers into national rivers. Especially, the fact that a lot of lands are being included mainly in local and small rivers mostly in summer is full of suggestions. Under this circumstance, small rivers should be expanded into local rivers, and local rivers should be expanded national rivers, and thus, they should be compensated for loss according to the special laws. Second, the finances for the compensation of unpaid sites in local rivers should be expanded. Namely, related laws and regulation should be reviewed in order that the compensation for loss can be made by giving rent profits of the land owned by the nation as finances for local governments. Third, the system for active compensation of loss should be arranged by newly establishing departments that are exclusively in charge of the enactment of ordinance for compensation of unpaid river sites and the performance of compensation. Fourth, systematic compensations should be performed by using data through researches on the actual condition of unpaid river sites.

CONTENTS<BR>  (1) RESEARCH OBJECTIVES<BR>  Founding company city is being driven as a new powerful way to solve the phenomenon of the imbalance between the Capital area and the districts and to prepare for the next century"s economic growth. This research compares the different views of the Federation of Korean Industries. the Citizens" Coalition for Economic Justice, and a government at the restitution of development gain. Furthermore, the improvement ways of reasonable restitution of gain are proposed.<BR>  (2) RESEARCH METHOD<BR>  It is used by literature reviews and survey analysis to achieve the purpose of this study<BR>  (3) RESEARCH RESULTS<BR>  The comparison of the views of F.K.I (The Federation of Korean Industries). C.C.E.J (The Citizens" Coalition for Economic Justice) and a government shows that the way of the development profit redemption is aimed principally at the redemption without taxes. It means that development profits should be redeemed into the costs of the basic equipment and the public facilities in the insides and outsides of development districts and should be invested. According to the survey, the restitution of development gain should be complemented by the improvement of an equal split, an additional tax re-introduction, and the improvement of a transfer income tax. So it is considered meaning to promote efficiency of the restitution of development gain by re-introducing the special additional cooperation tax abolished before.<BR>  2. RESULTS<BR>  We propose the possible solutions to build the successful company city. 1) Local government raises its" ability to lead the project with local research center and university. 2) The amounts of the restitution of development gain are considered by public characteristic. 3) The restitution of development gain should be achieved with development profit redemption of neighboring area. 4) The efficient taxes system should be accompanied with the restitution of development gain.

The objective of this study was to empirically analyze the asymmetric response of the housing market to the volatility shocks. Two regimes were assumed for the analysis and the analysis period was from January 2004 to December 2017. The analysis results of the study implied that, first of all, the housing market revealed volatility clustering. In other words, it showed considerable variations over a substantially long period and maintained a relatively stable period alternately. Moreover, the results of this study confirmed that there was a GARCH effect within each regime. Secondly, the variables affecting the housing price earning rate varied by regime. The exchange rate was the main variable of this study and it was more influential in regime 2 than in regime 1. Therefore, it would be important to manage the interest rate politically when an external shock occurs. Thirdly, the mortgage interest rate had different effects on the housing market in regime 1 and regime 2. It adversely affected the housing price agreeing with the theoretical basis during regime 1. However, it had positive effects on the housing price during the regime 2, accompanying with abrupt volatility. In other words, if a volatility shock occurs in the South Korean housing market, the volume of the mortgage loan will increase even though the price is rising.

1. CONTENTS (1) RESEARCH OBJECTIVES Recently the issue of long-term depression possibility is again raising since the real estate market is unstable and the domestic economic recovery comes to be late. This research examines the formation of the recent real estate price in Korea and diagnoses the possibility of depression by compared with the macro-economy index of 1990's macro-economy in Japan. In addition it provides the suggestion in order to overcome our difficult situation such as the unstable real estate market and prepare the possibility of deep depression. (2) RESEARCH METHOD In order to exam the possibility of the current real estate bubble, secondary data from first data obtained by Korean government, Bank, and so on are developed. Comparison method is used to compare Korean economy with Japan's. The informations of current policy are collected from the web-sites and articles (3) RESEARCH RESULTS This research presents the existence of real estate bubble but it is not dangerous level to be worried., There is not a possibility of bubble collapse because of low LTV, potential demand of residential house, and government's confrontation plan. However economy seems not easy to derail from depression due to high oil price and low export volume by Korean currency appreciation. The possibility of long-term depression exits if Korean government insists the current real estate policy and does not prepare the possibility of depression. 2. RESULTS We propose the possible solutions to escape from the long-term depression. 1) Government should not use too strong regulation policy of real estate to prevent real demand, 2) Government should focus on the preparation of depression not only the regulation of real estate. 3)It must prepare the suppression system which closes the excessive trust expansion of the financial institution against the hazard mortgage financing. 4) The trust among social members should be recovered to remove negative consuming habit and unstable future and the vision must be shown to achieve social value. 3.
