The educational methods have been changed with the development of computer and communication system. The emergence of internet has opened the age of information for education which can overcome the place and time restrictions of education and supply the information and knowledge required at any time and any place. The utilization of information equipments at the field of education establishes the effective remote education system through internet and then students can study at any place and any time according to their own abilities and conditions. While existing remote education systems have been focused on university students and common people, this thesis has embodies the remote education system for high school students. From the implemented remote education system, this thesis has obtained the following results. First, the individual learning ability of learners can be evaluated through formative evaluation and the individual learning suitable to each level can be provided. Second, the interactive education between teachers and learners Is possible through the various educational media using internet escaping from existing text centered education and then learning effects can be enhanced. Third, the learners'participation in interaction between teachers and leaners can be enhanced owing to the development of dynamic learning materials using HTML through Java script and CGI. Fourth, learners'participation and interaction can be increased by· easy question and answer beyond time and space by installing Q/A and free notice board.

아파트 경매 가격 결정요인에 관한 연구

정봉길 昌原大學校 2012 국내박사

Auction is, by definition, open competition and thus its price may be close to a transparent market price. However, while other real estate auction may involve some trouble in that participants have to investigate the property before attending the auction, apartment auctions may not require participant's any prior expertise because apartments are generally standardized on a regional basis throughout Korea. For this reason, it may be safe to say that the apartment auction price is a true market price determined by free competition with only regional differences. From this viewpoint of free market, this paper attempts to explain what affects the apartment auction price. To do so, this thesis assumes several hedonic and occupancy-related variables as its key factors and then tries to capture the effect of these separate variables on both appraised value and auction price of apartments. Semi-log regression analysis was conducted to identify the main factors. Auction data of three specific regions in Korea from 2006 to 2010 were employed in this analysis. The three regions can be representatives of high, moderate, and low price regions, respectively, in Korea. The price was adjusted to a consumer price index in December 2010 in consideration of inflation during the study period. The findings of this empirical study can be summarized as follows: First, in regions where the price is high and moderate, variables related to reconstruction represented by old age(over 18 years after construction) and low story(under 10 stories) appeared to have significant influence on both apartment auction price and appraised value. This means that the price of apartments with old age and low story becomes higher in some regions where the price is already high and moderate. This strange phenomenon can be explained by an expectation of reconstruction of obsolete apartments, which normally serves as an alternative to new construction in crowded areas with no spare space left for buildings and offers the owners some financial benefits such as gains through price rise in general and allotment of new apartments with better quality when reconstruction process is completed. In contrast, these factors did not show any sign of impact on the price in a low price region under this study. Second, scenic views also showed the most significant impact on the price in a high price region and showed relatively weaker impact in a moderate price region while in a low price region, they did not show any sign of effect on the price just as the variables related to an expectation of reconstruction did not affect the price. Third, there was no significant difference in a variable related to the direction of apartments, namely, preference for the south-face, because most apartments in Korea actually face the south. These findings can suggest that in regions where the price is high or moderate, people are more concerned about the quality of housing which can be represented by scenic views and reconstruction which is usually followed by better quality housing. There are some implications through these findings which housing constructors and governments alike should keep in mind: First, housing markets are, by nature, regional, not national markets. The characteristics of housing markets are completely distinct according to regions as evidenced in this analysis. Therefore, constructors and policy makers should not be confused concerning the regional differences when they make plans to provide housing in specific regions and follow appropriate guidelines based on these regional characteristics. Second, governmental officials should also consider regional differences when they establish housing policies. For example, they should reflect these regional characteristics in building new towns or providing new apartments via reconstruction to solve the problem of chronic shortage of housing in Seoul, metropolitan city of Korea. Since there seems to be a clear preference for better quality housing in Seoul which is represented as a high or a moderate region in this study, quality should go first before economy in providing housing in this region. However, in regions with relatively lower income thus the price being lower in general, there should be a supply of housing designed for practical use with lower price.

In this paper, I examine relationships between residential real estate prices and stock prices in Korea from 1995 to 2005. This paper is an interesting paper. Because people's wealth portfolio consists of real estate, stocks, deposit etc. In Korea, middle class owns homes. At same time, most home-owners are investors in financial markets. Investing in homes and financial assets are two major long-term investment decisions facing these investors. Changes in prices of homes and financial assets directly affect investors' equity values and their overall wealth, causing them to adjust their asset allocation in order to maximize their current levels of wealth. The real estate prices tend to go up after IMF financial crisis. The swings in stock prices have been large during 1990's. The residential real estate data are obtained from Kookmin bank's Seoul and Kangnam apartment price index. The stock price data are obtained from KOSPI in Korea stock exchange. Interest rate data are from Bank of Korea's CD interest rate. I first examine the existence of unit roots in the time series data including interest data under consideration. All time series data has a unit root. Three time series data are integrated according to Trace statistics using Johansen's approach. It means that there is a tendency for them to move together in the long run in equilibrium. Stock prices are found to Granger-cause residential real estate prices. But residential real estate prices are found not to Granger-cause stock prices.

저지연 LDPC 복호기의 하드웨어 설계 및 ARM 기반의 SoC 플렛폼을 이용한 오류 성능 검증

정봉길 건국대학교 대학원 2006 국내석사

한글초록:본 논문은 저지연 LDPC 복호기의 하드웨어를 설계하고 ARM 프로세서 기반의 SoC 플렛폼을 이용하여 오류 성능을 검증하였다. LDPC 코드는 국제 휴대 인터넷 표준 IEEE802.16e의 오류정정 부호로 채택 되었으며 본 논문에서 구현한 LTE-LDPC 코드는 IEEE802.16e에서 물리계층의 기술로 정해진 Structured-LDPC 부호류의 한 종류로 부호화 계산양을 효율적으로 줄인 LDPC 코드이다. LTE-LDPC 코드의 복호기인 저지연 LDPC 복호기는 반복 복호에 따른 복호 지연 시간을 줄이기 위해 병렬복호 방법을 이용한다. 저지연 LDPC 복호기는 부호기에서의 부호화 반복이 4회인 것을 바탕으로 4개의 SISO 모듈로 구성되었다. 병렬로 연결된 4개의 SISO 모듈은 동시에 병렬복호하여 그렇지 않은 경우와 비교하여 1/4로 지연시간을 줄였다. 또한 한정된 비트로 설계되는 복호기에서 사용하는 Min-sum 알고리듬의 최적 Scaling 인자를 Density evolution으로 구했다. 저지연 LDPC 복호기를 검증하기 위해 ARM 프로세서 기반의 SoC 플렛폼을 이용하였다. ARM 프로세서의 소프트웨어에서 LTE-LDPC 부호기의 동작을 수행하고 PLD 영역에는 저지연 LDPC 복호기를 구현하여 저지연 LDPC 복호기의 오류 성능을 검증하였다 영문초록:This thesis presents a performance for Semi-random LDPC codes and implementation of a low-latency LDPC decoder. The low-latency LDPC decoder was designed based on LDPC codes with semi-random parity check matrix which has less encoding complexity. Density evolution is used to analyze the scaling soft information in the min-sum iterative decoding algorithm. The thresholds are evaluated for various scaling factors. The optimal scaling factor is based on density evolution. For low-latency design we use parallel decoding. The low-latency LDPC decoder is composed of four SISO modules because encoder has four interleavers. Parallel decoding reduces the time delay by 1/4 compared to that of others. We verified the low-latency LDPC decoder with SoC platform based on ARM processor. The low-latency LDPC decoder is implemented on a FPGA in Altera's ExcalibureTM. We carried out error performance of low-latency LDPC decoder in a way that we implemented the low-latency LDPC decoder in PLD and generated codeword of LTE-LDPC encoder using ARM processor
