The c-erbB2/neu oncogene (alias HER2, NEU) encoding a tyrosine kinase receptor protein, the overexpression of which correlates with a more rapid progression and a worse prognosis in human breast cancer [1]. Otherwise, this gene is still poorly investigated in veterinary oncology [2,3]. To gain insight into the patterns of c-erbB2/neu status in canine mammary tumor, we constructed one such mammary tumor tissue microarray (TMA) from 60 tumors from our lab. This enabled the amplification of c-erbB2/neu oncogene of all 60 tumors to be simultaneously analyzed by chromogenic in situ hybridization (CISH). The aim of this study was to evaluate status of c-erbB2/neu oncogene in canine mammary tumors and to correlate this status with the differentiation grade of neoplasm. (omitted)

웹 애플리케이션의 사용이 늘어남에 따라 자바스크립트 프로그램의 성능을 높이는 것이 중요한 문제가 되었다. 자바스크립 프로그램에 대해 별칭 분석을 수행하면 더 많은 최적화가 가능해지지만, 자비스크립트가 가지는 동적인 특성으로 인해 분석 방법을 고안하는 데 어려움이 있었다. 본 논문에서는 자바스크립트의 주요한 동적 특성을 온전하게 다루는 별칭 분석 알고리즘을 최초로 제안한다. 제안한 방법은 별칭 그래프를 생성하여 프로그램 내의 별칭 관계를 완전하게 찾아내며, 또한 실행시킬 코드가 동적으로 추가될 때마다 이전에 이루어졌던 최적화가 유효한지 검사한다. 별칭 분석 결과를 이용하여 V8 자바스크립트 엔진에서 추가적으로 최적화를 수행한 결과, 유의미한 수행 시간 감소를 확인할 수 있었다.

KT114 상호/업종 검색 서비스에서는 데이터베이스 내의 동일한 개체에 대하여, 사용자가 입력한 상호명과 실제 데이터베이스에 저장된 상호명이 서로 다른 '통상명 검색 문자'가 존재한다. 이는 사용자가 인지하고 있는 상호명이 실제 상호명이 아니라 해당 상호의 대표적인 상표 혹은 상품명 등인 경우 발생한다. 본 논문에서는 이러한 '통상명 검색 문제'의 해결을 위하여 실제 상호와 사용자 인지 상호 간의 관계를 정의한 사전에 기반을 둔 해결 방안을 제안한다. 대용량의 자료에 대한 빠른 검색을 요구하는 시스템 특성상 사전의 구축 방식은 매우 중요한 문제이다. 본 논문에서는 사전을 구축하는 두 가지 서로 다른 접근 방법으로, 'DBMS 내부 구축 방식'과 '외부 사전 구축 방식'에 대하여 설명하고, 시스템 환경을 고려하여 두 접근 방법을 비교 및 분석한다.

This study examines the foremost concerns related to most noted research performance index. The most popular and widely acceptable h-index underestimates the highly visible scientist, the middle order group, due to citation distribution issues. The study addresses this issue and uses 'Corrected Quality Ratio' (CQ) to check the implicit underpinnings as evident in h-index. CQ helps to incorporate the aspects of a good research performance indicator. This simple revision performs more intimately and logically to gauge the broader research impact for all groups and highly visible scientists with less statistical error.

According to the customary, naming is done after the subject is in existence. But the name's Hae-ba-ra-gi(해바라기), 향일규(向日葵), 향일화(向日花))' has been used as an alias of Hibiscus manihot L.(닥풀) long before Helianthus annuus L.(sunflower) was brought in to Korea. And now the usage of the name has been conversed since them. Since the incorrect record of '葵藿' and '葵花'as '해바라기' in ${\ulcorner}$조선어사전(朝鮮語辭典)${\lrcorner}$(1920), the mistake has been carried on this must be corrected from now on. Incorrect record of hollyhock(蜀葵花) '해바라기' in ${\ulcorner}$몽유(蒙喩))${\lrcorner}$(1810) took a role in this incorrect trend.

This paper presents a design of network and database structure of the integrated system for power system operational planning and analysis that will be more economical and stable of power system operation. An alias of this system is Highly Integrated Total Energy System(HITES). The Client/server model of HITES is designed as a remote data management model. The input/output-type of application programs and Oracle server is standardized. The separated user-databases from main-database strengthen security of HITES. It is plan to do that tables and relationships are defined by database designs. The connection of application program and DBMS of HITES will be tested through database design and data construction.

This paper presents a database design for power system operational planning system of the integrated system for power system operational planning and analysis that will be more economical and stable of power system operation. An alias of the integrated system is Highly Integrated Total Energy System(HITES). We first describe the requirements for the Power System Planning System of HTES. Database design is processed in two phases(conceptual design and physical design), and CDM(Conceptual Data Model) and PDM(Physical Data Model) are generated by Powerdesigner(CASE tool for database design). In the future, the constructed database needs to be tested and tuning.

A scheme for missing-trace interpolation of linear events is proposed. For a two-dimensional seismic dataset which contains linear events, a post-interpolation spectrum can be estimated from a portion of the original aliased spectrum. The restoration of missing trace data is accomplished by minimizing the energy after applying a filter which has an amplitude spectrum that is inverse to the estimated spectrum.

The velocity of train which is measured from pulse generator attached to TM is used for displaying or control signal of inverter and so on. Measured signals increase and decrease step-by-step by pulse counting or monotonously by F/V conversion. But noises and signal distortions by measuring error like alias make it difficult to provide correct velocity infomation and estimate the acceleration. In this paper, we investigated the performance of Smoothing method for suppressing the noises in velocity signals. And the difference between Smoothed signal and origin velocity signals is inspected and the comparison with low pass filtering show applicable of Smoothing method for noise rejection and the estimation of signal. Finally, acceleration curves estimated from Smoothing method are compared with real accelerator signal attached to train.
