EasyLab은 다양한 부류의 학습자에게 기본적인 알고리즘 교육을 제공하여, 창의성과 논리성 계발의 효과를 거둘 수 있도록 만들어진 시스템이다. 학습자는 EasyLab을 통해 자신이 의도한 바를 알고리즘화 시켜 프로그래밍하고, 그 코드를 USB로 연결된 아바타 로봇으로 전송할 수 있다. 그러면 로봇은 프로그램화된 코드에 의해 반응을 하게 되고, 학습자는 자신의 의도와 비교, 연구, 반복할 수 있다. EasyLab은 초보자가 학습하기 쉽도록 GUI 방식을 사용하기 때문에 알고리즘 교육에 효율적으로 사용할 수 있다.

This res arch was conducted to identify a suitable location for an inland logistics complex in Gangwon Province, South Korea and it aims use competitive factors to derive implications from the logistics competitiveness of Gangwon Province. According to Origin-Destination analysis, the most suitable and desirable site for creating the complex was found to be in the Wonju city area. A total of 28 variable were derived through prior study in order to identify the competition factors for the inland logistics complex, As a result of exploratory factor analysis, a total of 16 subfactors were reclassified into four main factors. Analytic hierarchy process(AHP) analysis showed that 'accessibility factors' (0.374) ranked highest in terms of importance, followed by 'reliability factors' (0.358), 'operability factors' (0.166), and 'government policy factors' (0.102). In each category, delivery of goods from the inland logistics complex base to the demand site was found to be the most important factor (0.160).

상수도 체계는 크게 생산적인 측면, 유통적인 측면, 하수적인 측면으로 나눌 수 있다. 이중 생산적인 측면과 하수적인 측면은 자동화를 위한 많은 연구가 진행되어 현재 대부분 자동화 되어 있다. 하지만 유통적인 측면은 여러 가지 이유들로 아직까지 그 자동화 정도가 매우 미미한 수준이다. 본 논문에서는 상수도 체계 중 유통적인 측면의 자동화를 위해 가장 핵심이 되는 요소인 유량계의 검침을 유량계 자동검침 중계기를 이용하여 자동화 시킨 다음 유 무선 통신을 통하여 원격지(상수도사업소)에서 일괄 관리할 수 있는 "유량계 자동검침중계기를 이용한 상수도 관리 시스템"를 소개한다.

In this paper, the reconstruction scheme of lost block in the transmission of block coded image is proposed. Due to differential coding of dc coefficient in JPEG images when JPEG image are transmitted over wireless communications, the effect of errors can destroy entire blocks of the image. Therefore, we aim to reconstruct the lost information using correlation between the lost block and its neighbor blocks. In order to evaluate the performance of this scheme, we inserted some intentional block error into the test images. And we obtained good results objectively and subjectively by experiments.

A general web-based remote lecture system uses video data and audio data to provide synchronize between teacher and students. This system requires high bandwidth, high speed networking, television, compression and computing technologies between server and client for remote lecture over Internet. As a result, this system can decrease an efficiency for lecturing over current Internet. So, this paper proposes a new mechanism calling as ‘Synchronization of WWW browsers between server and client’to cope with above problems and finally pursues low cost needed for real-time remote lecture over Internet. The mechanism means that every browser of teacher and students displays the same page and the action of teacher is transferred to the browser of student. And, this can be implemented by Windows hooking APIs, Memory Mapping, and DLL (Dynamic Link Library) programming technology. This paper points to the design and implementation of LAS (Lecture Assistant Server) and LAC (Lecture Assistant Client) to perform the synchronization between server and client.

Due to NxN block coding blocking artifacts are exhibited by block-based DCT coding images, primarily at low bit rates. In this letter, we propose the new technique that reduce the blocking artifacts pixels in such images. In the case of combining with list block reconstruction techniques, our algorithm can be also used to improve image qiality. And, the performance of the proposed algorithm is demonstrated experimentally.

인터넷 사용 확산에 따라 원격강의 시스템 또한 웹 서비스를 지향하는 추세이다. 웹 기반 원격강의 시스템의 형태로는 서버와 클라이언트의 브라우저를 동기화시키는 실시간 원격강의 및 단순히 강의자료를 웹서버에 올려두고 사용자가 접속하여 이용하도록 하는 비실시간 원격강의 등이 있다. 이러한 원격강의 시스템들은 결국 사용자의 pc에 이미 설치되어 있는 웹브라우저를 이용하는 것으로서 전용시스템 설치에 대한 부담을 없애주고 있다. 그러나 이러한 형태의 원격강의 시스템의 경우 강의 교재가 HTML 문서이어야 하는 번거로움이 발생하게 된다. 본 논문에서는 이미 PC용으로 널리 사용되는 윈도우즈용 프레젠테이션 도구의 문서를 강의 교재로 사용할 수 있게 하는 실시간 원격강의 시스템을 설계한다.

This study was carried out to investigate a usefulness of the microsatellite DNA markers for individual identification and parentage verification in three dog breeds. A total of 59 random dog (31 Chiwawa, 20 Poongsan, 8 Labrador Retriever) samples were genotyped by using 14 markers (Chiwawa dog), 16 markers (Poongsan dog), and 12 markers (Labrador Retriever dog) among the 17 international standard markers (PEZ1, 3, 5, 6, 8, 10, 11, 12, 13, 15, 16, 17, 20, 21, FHC2010, FHC2054 and FHC2079), respectively. The number of alleles per locus varied from 4 to 14 with a mean value of 6.07 in Chiwawa dog, 2 to 9 with a mean of 4.75 in Poongsan dog, and 3 to 5 with a mean of 4.00 in Labrador Retriever dog. Observed heterozygosity was ranged 0.419${\sim}$0.968 (mean 0.755), 0.300${\sim}$0.950 (mean 0.597) and 0.125${\sim}$0.750 (mean 0.604), and expected heterozygosity was ranged 0.432${\sim}$0.883 (mean 0.711), 0.262${\sim}$0.817 (mean 0.559) and 0.425${\sim}$0.808 (mean 0.660) in these three dog breeds. PIC value was ranged 0.397${\sim}$0.856 (mean 0.659), 0.222${\sim}$0.772 (mean 0.503) and 0.354${\sim}$0.717 (mean 0.563) in these three dog breeds. Of the 17 markers, PEZ1, PEZ3, PEZ6, PEZ10, PEZ12 loci, PEZ1, PEZ6, PEZ13 loci, and PEZ8, PEZ12 loci have relatively high PIC value (＞0.7) in Chiwawa dog, Poongsan dog and Labrador Retriever dog, respectively. The exclusion probability was ranged 0.240${\sim}$0.741, 0.111${\sim}$0.616, and 0.198${\sim}$0.529, and the combination of microsatellite loci was 0.9999, 0.9991, and 0.9968 in Chiwawa dog, Poongsan dog and Labrador Retriever dog, respectively. These results can give basic information for developing parentage verification and individual identification system in these three dog breeds.

This paper attempts to explore how Ang Lee depicts Asian and Western women in his films. We focus on two parts of his consciousness First, Ang Lee does not consider himself a feminist, he understands the world in terms of women who play societal roles. Second, Ang Lee's films reflect his identity in a juxtaposition model, in which he is a member of mainstream American society and also holds an onlooker's viewpoint at the same time. He depicts women, who are often marginalized or considered the minority, and their feminist ideals, as means that break down the authority of the father and the man, the traditional ideology, and the male dominant nationalism. Chinese women in movies divide apart traditional Chinese patriarchal ideology and male-dominated anti-Japanese sentiments. Also, the Western women in his films reveal the non-stereotypical appearance of Western society in the 1970s and 1980s, with daily tension, anxiety, abdominal pain and anger, silence and anxiety about homosexual husbands, and excessive obsession. The director's portrayal of women not only separates the male-centered and Western-centered discourse, but also reveals a self-division of internalized masculine patriarchal Asian thought consciousness.

This study aimed to examine the dilemma of rural China under rapid urbanization process after economic reform, by paying attention to the problem of the order of village community and the expression of individual desires depicted in the film with a rural background. To this end, the narrative analysis, which is suitable for exploring the story structure and expression style of the text, was conducted to examine the community order and ethics, patriarchy and paternity, and the expression of desires of subject. In the film, closed space and villagers, who are disciplined by community customs, local culture, and formality of the rule of manners, are depicted. The film is covered in a form of mystery movie dealing with the deaths of members of the village community. However, the film talks about the rise of the Imaginary desire of subject against the symbolic rules of community order and ethics through the puzzle pieces story according to the perspectives of the characters. In conclusion, through the narrative analysis, it was possible to examine the implications of weakened communal discipline and paternity of the countryside by the rapid urbanization of China, and implications of the lethargy and neurosis of the subjects.
