This study is the analytic research of items having gender gap in 6th grade students in 'National Assessment of Educational Achievement(NAEA)'. For this problem solving, the following was investigated. First, items having gender gap were selected in NAEA for the past eight years. Then, the mathematical factors that cause gender gap were analyzed. Second, to do this the field test was developed using item concept map. Finally, after the analysis of field test result the reason of gender gap was deduced. Through this study the improvement of mathematics teaching and learning method in elementary school is expected.

This paper proposes GAPS, a practical genetic algorithm based pathfinding system for conveniently analyzing various networks. To this end, the GAPS is developed through integration of the intuitive graphic user interface for network modeling, the database management system for managing the data generated in modeling and exploring procedures, and a simple genetic algorithm for analyzing a wide range of networks. Especially, previous genetic algorithms are not appropriate for analyzing the networks with many dead-ends where there are few feasible paths between the given two nodes, however, GAPS is based on the genetic algorithm with the fitness function appropriate for evaluating both feasible and infeasible paths, which enables GAPS to analyze a wide range of networks while maintaining the diversity of the population. The experiment results reveal that GAPS can be used to analyze both networks with many dead-ends and networks with few dead-ends conveniently, and GAPS has several advantages over the previous genetic algorithms for pathfinding problems.

시스템 요구사항과 소프트웨어 재사용 컴포넌트 간의 Gap 분석을 통해 컴포넌트의 재사용 커버리지를 측정함으로써 부적절한 재사용 컴포넌트를 구분해 내거나 대안 컴포넌트 중 가장 재사용 커버리지가 높은 컴포넌트를 선택하는 방법을 제안한다. Gap 분석의 방법으로 기능적, 비기능적 지표가 고려된 FP(Function Point) 분석 방법의 사용을 통한 재사용컴포넌트의 평가 프로세스에 대해 설명한다. 재사용컴포넌트 평가 프로세스에 의해 계산된 수치화된 시스템요구사항과 재사용컴포넌트간의 커버리지 비율을 통해, 소프트웨어 재사용 방해요소인 부적절한 라이브러리의 사용, 신뢰성이 떨어지는 모듈, 성능격감 의 문제점들을 줄이거나 해결함으로써 소프트웨어 재사용의 비율을 높이고 이는 비용절감으로 이어져 보다 성공적인 소프트웨어 개발 프로젝트를 기대할 수 있다.

This paper attempts to conceptually examine the potential of IPTV(Internet Protocol Television). First, this paper reviews the concept of a bridging telecommunication service and a gap-filling telecommunications service. Second, the current status of various emerging telecommunications services including mobile WiMax, called WiBro, and both satellite and terrestrial digital multimedia broadcasting service, called DMB are comprehensively analyzed. Based on those analysis, this paper analyzes whether IPTV is regared as a bridging telecommunications service or a gap-filling telecommunications service and examine the potential growth possibility of IPTV. Finally, the suggestions for policy makers are discussed.

Since 2009 The Korean National Police Agency has been pushed "permissive left-turn" forward in order to making progress in Korean traffic operations system. Preceding researches manuals and guidelines present 6 standards(# of accidents # of lanes, pedestrian volume sight # of permissive left-turn lanes vehicle volume) as installation permissive left-turn. But in practical affairs it is most important that secure enough Gap-time between permissive left-turn vehicle and opposite through lane vehicle to make permissive left-turn vehicle move safer and more efficiently. This study suggests applying gap acceptance theory in microscopic model to permissive left-turn installation standards. Analysis methods of this study are field data survey statistical analysis and microscopic simulation analysis. This study collected field data by using AVI recording and measured permissive left-turn vehicle intersection passing time(T1) and against the opposite through lane vehicle Gap-time(T2). And statistical analysis performed about two values that measured before to predict the functionality between T1 and T2. These studies to overcome the limit of sample size carried out a microscopic simulation(VISSIM) plan and collect more samples to input statistical analysis.

Gap parsing is an algorithm for parsing incomplete input strings which include some gaps. Gap parsing is different from conventional parsing, and as known results, one-gap parsing algorithms for arbitrary context-free grammar and LL(1) grammar have $O(n^3)$ and $O(n^2)$ time complexity, respectively. This paper presents a one-gap parsing algorithm for extended PLR(1) grammars. Extended PLR(1) grammars are the class of grammars smaller than LR(1) but much larger than LL(1). The one-gap parsing algorithm of the grammar class is shown to have the time complexity of $O(n^2)$, which is equal to the complexity of one-gap parsing algorithms for LL(1) grammars.

This study aims to analyze the relationship between the expectation of franchisees to their franchisers before contracting and perceived performance after actually operation. The analysis data was collected from 789 franchisees located in Seoul and Gyeonggi-do of South Korea. The findings are as followings: first, the gap between expectation of franchisees and perceived performance was negative and it becomes an necessary for franchise managers to manage the expectation of franchisees by using various effective marketing strategies. Second, the gaps were different among different franchise industrial classifications and the gap in the food-service industry is the largest.

There has been little consensus on how to define and use the Korean mathematical terms, bi-ui-gap and bi-yul. This study compares four perspectives of bi-ui-gap and bi-yul proposed and discussed in Korean mathematics education community and examines the ways of using the terms adopted since the 6th national curriculum. Based on the analysis that previously proposed perspectives conflict each other, this study proposes as a way to synthesize different perspectives of bi-ui-gap and bi-yul by analyzing the terms in the internal and external ratio contexts. This study proposes that bi-ui-gap be used to represent 'a value of $A{\div}B$' rather than 'a value originated from a ratio A:B' or 'a fraction form ${\frac{B}{A}}$.' This study also proposes that bi-yul or bae-yul be used in the internal ratio context and a new term, such as dan-wi-yul, be created for the external ratio context.

Ever expanding overseas construction is one of the most important issues for Korean construction companies. Among these issues, strategies for overseas plant construction have widely been discussed, because the plant construction has features of low competitiveness and high ripple effects when compared with other construction sectors. In this sense, the purpose of this research is to evaluate the CM capability of Korean construction industry for overseas plant construction. Fourteen construction business functions and four techniques were defined first. Based on these functions and techniques, CM capability was quantified for As-Is (2013), To-Be (2018) and Gap analyses. Findings of this research reveal that 1) capability for construction is quite competent, 2) capabilities for planning, design management, contracting, and risk management are found to be relatively low, where higher value can be added. In addition, it is found that R&D needs to be extended to develop systemized management techniques. It is also required to secure specialists and original technologies at national industrial level.
