This paper has focused on the geographical patterns of migrations and the influence of housing value(apartment) per pyung on the migrations within the one city(Seoul) for 1995$\sim$2003. The migration flows which are composed of the origin, the destination and the number of migrants, are examined at the administrative gu and dong level. As most migrations occur among adjacent gus and dongs, short-distance migration is prominent But there is a tendency for the short-distance migrations to occur between specific regions. Since the economic crisis of 1997 out of which Korea was rescued by IMF, differentiation of housing price is so evident that residental relocation is selective among dongs. It seems that the differentiation of housing price has begun to facilitate the relocation of households. Certain social groups are excluded from high-quality residences, as they cannot afford the high price. The number of migrants between dongs is closely related to the variation of the housing value per pyung within dongs. The short-distance migration may reflect this phenomena simultaneously. It seems that the intra-urban migrations in Seoul play a important role to produce and reinforce the residential segregation.

The United Nations Convention on Contract for the International Sale of Goods(CISG) is legislated for unified of international sale of goods, but does not cover all concerns related to that. Arilce 4 provides the exclusions of CISG. These exclusions might be govern by a domestic law. This paper analyses what are excluding under CISG Article 4, and then provides the Korean and Chinese domestic regulations related to them. At first, whether some issues are excluding based on the interpretation of CISG Article 4 depends on the agreement of parties concerned. An issue that a national law applies even might be invalid if it does not follow the general principles of CISG. In Conclusion, CISG does not cover the validity of the contract and the property in the goods sold under CISG Article 4. a company who trades with Chines company should understand the differences of both countries' regulations about the validity of the contract and the effect of property transfer and be careful to decide a govern law to avoid unnecessary disputes about these issues even though their contract is govern by CISG.

The purpose of this paper is to examine the determinants which cause a price differential between common and preferred stock. Prior studies have shown that variables like liquidity, size, the number of outstanding shares issued can explain the price differential between common and preferred stock price. Based on year 2006 through year 2008 data, we analyzed the determinants using regression model. Dummy variables representing large/small company and KSE/KOSDAQ respectively are added and analyzed as independent variables. The firm size, trade volume turnover, and the number of preferred shares to total outstanding shares were proved to make influence on the price differential under the 5% significance level. Especially, we have found the number of preferred shares to total outstanding shares provide the most strong relationship with the price differential. This means that a high ratio of preferred stock to total outstanding shares leads to relatively high value of common stock and causes a big price differential.

In current algorithm trading system, general users need to program their algorithms using programing language and APIs provided from financial companies. Therefore, such environment keeps general personal investors away from using algorithm trading. Therefore, this paper focuses on developing user-friendly algorithm trading system which enables general investors to make their own trading algorithms without knowledge on program language and APIs. In the system, investors input their investment criteria through user interface and this automatically creates their own trading algorithms. The proposed system is composed with two parts: server intercommunicating with financial company server to send and to receive financial informations for trading, and client including user convenience-based user interface representing secondary indexes and strategies, and a part generating algorithm. The proposed system performance is proven through simulated-investment in which user sets up his investment strategy, algorithm is generated, and trading is performed based on the algorithm

With the rapid increase in the price of house lease, a unique housing form in Korea, a serious social issue has been raised as to the use value of house lease and residence stability of the ordinary people. This study thus aimed to analyze the direct factors that affect lease guaranteed loan and market volatility in order to explore the right direction of financial policy to reduce housing burdens. To this end, the direct variables affecting house lease guaranteed loan, including lease price, transaction price and lending rate, were defined. Vector Error Correction Model (VECM), a time series analysis, was employed to dynamically explain the data. Based on the house lease prices and bank data on loans between January 2010 and December 2014, it was found that the increase in lease price was the direct result of the increase in lease guaranteed loan, not that of the decrease in lending rate or increase in housing transaction price.

The purpose of this paper is to provide a legal implication about conformity of goods in the international commercial transactions. There are so many legal relationship after the formation of contract. The most of important thing among the obligations of seller is to provide conformal goods which are of quantity, quality and description required by the contract and which are contained or packaged in the manner required by the contract. If seller violate above duties, seller take the warranty liability. However, CISG describe the conformity of the goods instead of the warranty as follows. First, CISG Art.35(1) states standards for determining whether goods delivered by the seller conform to the contract and Art.35(2) describes standards relating to the goods' quality, function and packaging that, while not mandatory, are presumed to be a part of sales contracts. Article 35(2) is comprised of four subparts. Two of the subparts (article 35(2) (a) and article 35(2)(d)) apply to all contracts unless the parties have agreed otherwise. Second, CISG Art.36 and 38 deals with the time at which a lack of conformity in the goods must have arisen in order for the seller to be liable for it. If seller lack of conformity becomes apparent only after that time, seller is liable for a lack of conformity existing when risk passed to the buyer. Third, CISG Art.49 describe that a buyer who claims that delivered goods do not conform to the contract has an obligation to give the seller notice of the lack of conformity. The most of important things about CISG articles and precedents is that buyer is aware of the lack of conformity and notice it to seller. Failure to satisfy the notice requirements of article 39 eliminates a buyer's defence, based on a lack of conformity in delivered goods, to a seller's claim for payment of the price. Consequently, parties of contract had better agree to the notifying times about lack of conformity. Also, If seller fined the non-conformity, seller has to notify this circumstance to the buyer within short period or agreed time.

The purpose of this study is to analyze the effect of the results of a nationwide academic evaluation of middle schools and high schools on apartment prices in Ulsan City by using a hedonic pricing model. The results of the middle school and high school achievement test, the College Scholastic Ability Test (CSAT) score for high school, the national united evaluation score, and the number of successful applicants to prestigious universities have a significant effect on the apartment price formation with a positive relationship. In addition, different kinds of academic evaluation score have asymmetric effects on apartment price determination. The results of the high school achievement evaluation are more important than the results of the middle school achievement evaluation in the apartment price determination. Among the achievement evaluation results, the ratio of the students with the higher education level is more important than the ratio of the students with the lower basic education level. Furthermore, the CSAT score for Natural Sciences is more important than the CSAT score for the Humanities course.

This study estimated the impact of the shock of housing price increase on the total fertility rate and the contribution of each variable to changes in the TFR. This study is differentiated by estimating the contribution rate of each variable to the fertility rate through the Shapley decomposition and the panel VAR's forecast error variance decomposition, which previous studies have not attempted. The main results of this study are as follows. First, the decline in the TFR in Korea has been strongly influenced by the recent decline in the total fertility rate, and this influence is expected to continue in the future. In the case of housing costs, in the past, housing sales prices had a relatively small contribution to changes in the total fertility rate compared to the jeonse prices, but their influence is expected to increase in the long term in the future. It has been demonstrated that private education expenses other than housing sale price and Jeonse price also acted as a major cause of the decline in the total fertility rate.
