This study The study analyzed the effect of the advertisement method of admission at Korea Polytechnic University on the competition rate for entrance to university. A total of 66 questionnaires were analyzed among freshmen and undergraduates at Korea Polytechnic University in Seoul. The first study revealed that the ground promotion (p<.01, ${\beta}=.363$) had an effect on the competition rate, with the ground promotion having a statistical effect on the competition rate and therefore having a significant competitive edge. Second, it was analyzed that the ground promotion and registration rates were correlated to the $p{\times}.01$ level with the. 297 level of media promotion and registration rates. Third, although the motivation for knowing the junior high school records and the Korean Polytechnic University did not significantly affect the registration rates, it was found that there were group differences because the admission patterns were higher than usual on time. This study analyzes the effect of the admission promotion method on the competition rate of the university, identifying the importance of ground advertisement, media promotion to the competition rate and registration rate, and identifying the effectiveness of characteristic factors.

This paper deals with fast competitive learning using classified learning rates. The basic idea of the proposed method is to assign a classified learning rate to each weight vector. The weight vector associated with an output node is updated using its own learning rate. Each learning rate is changed only when its corresponding output node wins the competition, and the learning rates of the losing nodes are not changed. The experimental results obtained with image vector quantization show that the proposed method learns more rapidly and yields better quality that conventional competitive learning.

대학 행정의 전산화 프로젝트는 여러 부분에서 진행되어 왔다. 본 논문은 학사 행정 업무에 관한 프로토타입으로 사용될 목적으로 개발되었으며, 웹에 대학 지원 경쟁률을 실시간으로 사용자에게 보여지도록 했다. 개발 환경은 Unix 운영체제에 오라클 데이터 베이스가 기반이며 호스트 언어로 Pro*C를 사용하였다. 구현 원리는 TCP/IP 프로토콜을 거치지 않고 웹 서버를 이용하여 웹 상에 데이터베이스의 데이터를 주기적으로 갱신하여 보여준다는 점이 특색이다.

In 2009, the Korean international construction industry showed a great performance, totaling 49.1 billion of contract and then this achievement has been considered a key milestone presenting that the international construction industry is one of the primary export industries of Korea. However, because of the construction firms' equalized levels of technology and price competitiveness, the competition among bidders is becoming more intensive. Moreover, this changing market circumstance leads construction firms to apply for bidding with the lowest price that could not meet the expected profitability of a project. Therefore, to develop various strategies based on project characteristics becomes one of the critical capabilities that construction firms should possess. Based on these motives, this study is aimed to investigate associations among number of bidders, contract award rate, profitability on international projects. For the correlation analysis, a set of data is structured by collecting all projects ranging from 1993 to 2009, excluding projects funded by official development and domestic funds. The number of bidders were grouped depending on project characteristics such as market regions, project types, bidding types, and order organization types. As the result of correlation analysis, contract award rate increases as the number of bidders increase, but the relationship between the number of bidders and profitability is negative. Understanding the correlations among variables can be employed in developing strategies to improve construction firms' competitiveness in the international construction market.

CP(Counterpropagation) 알고리즘은 Kohonen의 경쟁 네트워크와 Grossberg의 아웃스타(outstar) 구조의 결합으로 이루어진 것으로 패턴 매칭, 패턴 분류, 통계적인 분석 및 데이터 압축 등 활용분야가 다양하고, 다른 신경망 모델에 비해 학습이 매우 빠르다는 장점이 있다. 하지만 CP 알고리즘은 충분한 경쟁층의 수가 설정되지 않아 경쟁층에서 학습이 불안정하고, 여권 코드와 같이 다양한 패턴으로 그성된 경우에는 패턴들을 정확히 분류할 수 없는 단점이 있다. 그리고 CP 알고리즘은 출력층에서 연결강도를 조정할 때, 학습률에 따라 학습 및 인식 성능이 좌우된다. 따라서 본 논문에서는 패턴 인식 성능을 개선하기 위해 다수의 경쟁층을 설정하고, 입력 벡터와 숭자 뉴런의 대표 벡터간의 차이와 숭자 뉴런의 빈도수를 학습률 조정에 반영하여 학습률을 동적으로 조정하여 경쟁층에서 안정적으로 학습되도록 하고, 출력층의 연결강도 조정시 이전 연결 강도 변화량을 반영하는 모멘텀(momentum)학습법을 적용한 개선된 CP 알고리즘을 제안한다. 학습 성능을 확인하기 위해서 실제 여권에서 추출된 개별 코드를 대상으로 실험한 결과, 본 논문에서 개선한 CP 알고리즘이 기존의 CP 알고리즘보다 패턴 분류의 정확성과 인식 성능이 개선된 것을 확인하였다.

This study examined whether industry-level competition affects excess stock returns because of changes in cash holdings. Competitive inter-company threats increase the possibility of the manager's replacement, and function to induce management to make their best efforts, resulting in the amount and quality of the information provided by the enterprise increasing. Therefore, as competition intensifies, agency problems are reduced and stock returns increase because the company's cash holdings are expected to increase. However, there is a view that firms in industries with severe competition tend to have high information asymmetry because competitors may compete in more favorable positions by using detailed information disclosed by the competing firms. Accordingly, as market competition intensifies, the excess stock returns resulting from increased cash holdings are expected to decline. These results show that excess stock returns because of increases in cash holdings increase as the degree of competition in the industry intensifies, thus supporting the positive effect of market competition. Overall, the results of this study provide an understanding that market competition plays an effective external governance mechanism and that investors positively evaluate the cash held by companies with severe industry competition.

Recently, as the construction industry trend is changed to the market orientation which focuses on the autonomy and competition, the most construction companies try to adapt the new environment. Thus, this study analyzes the correlations of business strategy and core competency taken by the construction company to survive from the rapidly changing environment between the growth rate and rate of return of the company. Throughout the existing researches and theoretical studies, a business strategy and core competency of the construction company is drawn, and based on this, this study surveyed 746 construction companies. The results of the survey showed that the business strategy has any relationship with growth rate and rate of return and the core competency of the construction company has no relationship with rate of return either, while the core competency shows the relationship with the growth rate. Thus, it is analyzed that the construction company which has higher growth rate also has the high core competency level.

DOCSIS 3.0 Protocol is proposed to make the advance of HFC network. In the DOCSIS based network, the upstream frame is divided into contention section reservation section. CMs to have packets send request messages through the contention section. That two or more CMs sends Request message at the same contention slot makes collison. In this paper, are propose the contention section establlish at algorithm considering of channel-bonding mechanism that is the primary technique of DOCSIS 3.0. Results of simulation display better performance int the number of contention slots and the utilization of contention section.

기존에는 통신시장에 진출하려면 막대한 설비투자와 사업권의 획득이 필요했으나 이제는 망을 비롯한 주요 설비 없이도 사업을 할 수 있는 기회가 열렸다. 이러한 통신사업에 대한 신규진출 규제완화 움직임은 이동통신시장 경쟁구도의 변화뿐만 아니라 통신 산업 전반에 큰 영향을 미칠 것으로 기대되고 있다. 본 연구는 정부의 재판매(MVNO)제도의 도입과 관련하여 합리적인 도매대가 산정방안에 대한 고찰을 목적으로 다음과 같은 결론을 도출하였다. COST PLUS 모형과 RETAIL MINUS 모형에 각각 영업이익률과 원가 대비이익률을 적용하여 도매대가를 산출한 결과 원가대비이익률을 적용하여 RETAIL MINUS 모형으로 산출했을 때 가장 높은 도매대가가 산출되었다. 반면 도매대가가 가장 작은 모형은 영업이익률 적용 RETAIL MINUS 모형으로 나타났다. 이러한 결과는 도매대가산정 시 비용의 구분과 이익률의 산정이 중요한 요소로 작용하였으며, 이를 통해 보다 정교한 MVNO 도매대가산정을 할 수 있을 것으로 기대된다.
