  • 제품계열분석(product line analysis)은 제품계열자산(product line asset)을 개발하기에 앞서, 제품계열 내에 속한 제품들의 다양한 요구사항과 이들 간의 관계 및 제약사항을 분석하는 활동을 말한다. 지금까지 특성모델링(feature modeling)이라 불리는 특성 지향의 공통성과 가변성 분석은 제품계열분석의 핵심적인 부분으로 간주되어 왔다. 비록 공통성과 가변성 분석이 제품계열분석의 핵심적인 요소이지만, 이것만으로는 재사용가능하고 적응성이 뛰어난 제품계열자산(예, 아키텍처와 컴포넌트) 개발에 한계가 있다. 특성간의 의존성 및 특성결합시간도 제품계열자산 개발에 중대한 영향을 미치는 요소이다. 따라서 본 논문에서는 기존에 공통성과 가변성 관점에서 제품계열을 분석한 결과인 특성모델(feature model)을 세 가지의 특성 측면(즉, 제품특성의 공통성과 가변성, 특성간의 의존성, 그리고 특성결합시간)으로 확장한 특성지향의 제품계열분석 모델을 제안한다. 특히, 세 가지 측면의 일관성을 검증하기 위해서, 특성 지향의 제품계열분석 모델을 정형적으로 정의하고, 모델의 일관성을 검사하는 규칙을 제공한다.

  • The linear support vector machine(SVM) is motivated by the maximal margin separating hyperplane and is a popular tool for binary classification tasks. Many studies exist on the consistency properties of SVM; however, it is unknown whether the linear SVM is consistent for estimating the optimal classification boundary even in the simple case of two Gaussian classes with a common covariance, where the optimal classification boundary is linear. In this paper we show that the linear SVM can be inconsistent in the univariate Gaussian classification problem with a common variance, even when the best tuning parameter is used.

  • This study revises current feasibility evaluation guideline for agricultural infrastructure improvement project considering recent changes in social and economic environment in rural area. We use an AHP(Analytic Hierarchy Process) approach to consider qualitative evaluation items in policy enforcement and balanced regional development as well as quantitative items in current economic analysis in the process of feasibility evaluation and decision making. The criteria system is composed of three level hierarchy. In the first level which consists of economic analysis, policy analysis, and regional development analysis, economic analysis was ranked top with relative weight of 0.45 and regional development analysis the lowest with 0.22. In the second level which consists of three evaluation items under policy analysis, consistency in policy enforcement, risk factors, and special evaluation factors, consistency in policy enforcement was ranked top. Finally, 13 detailed evaluation items in the third level were surveyed and ranked by using a comprehensive criticality vector. The result shows that the three most important evaluation items are 'degree of underdevelopment', 'spill-over effect of regional economy' and 'consistency with related planning and policy direction'.

  • This study investigated the correlation between the level of consistency in fashion show models' appearance and design concept through a statistical and qualitative analysis of the S/S Paris Collection 2014. The following conclusions have been drawn in this study. First, the percentage of models of color was very low in regards to the physical appearance of models; in addition, there was a higher percentage of Caucasian models for collections with a high level of consistency in models' physical appearance. Collections with a high percentage of models of color indicate more casual design concepts and the promotion of diversity in racial background is considered more effective for street fashion. Second, collections with a high level of consistency in models' physical appearance tend to control various elements that constitute a physical appearance through more detailed planning and stage direction. Third, there is a tendency to reinforce design concepts by creating a consistency in the overall physical appearance of models. This affirms that their physical appearance is determined by brand (i.e. designer) and is used to maximize a design concept delivery. The results of this study suggests that the physical appearance of models must be determined in line with the design concept versus detailed planning that must consider audience perspectives as well as adjust the show's length and the interval between each model appearing on the stage.

  • The aim of the present study was to measure intra-individual consistency in clothing style evaluation and to examine its relation to the ratings. For this study, a pilot test was conducted to 50 clothing majored university students to explore the stimulus of‘cute’,‘casual’,‘sexy’,‘elegant’,‘intelligent’,‘formal’,‘romantic’,‘individual’,‘refined’for the 9 each image styles from the 32 spring wears in fashion magazine$\boxDr$FARBE$\boxUl$(March, 2000). On the basis of the preliminary survey, the question items explored the 15 pairs of bipolar adjectives as seven-point Likert type. The main survey was preceded 94 female and 111 men of university students from March 13 to 24 in 2000, twice for 7-days interval. As a result of analyzing of correlation coefficients between the two ratings for each subjects, intra-individual consistency in the evaluation, ranged from -.11 to .87 and mean coefficient was .64 of female and .20 to .76 and mean coefficient was .57 of male. Female had higher intra-individual consistency in the evaluation than male. Based on the coefficients, the subjects were classified into three groups: high, medium, and low intra-individual consistency. Analysis of variance of mean ratings by the three groups revealed that significant difference existed in 42% of female and 25% of male in 135 combinations of 9 clothing and 15 semantic differential scales. There was an apparent tendency that subjects of female with high intra-individual consistency were mostly definitely to evaluate clothing, whereas the ones with low were least. But male shows opposit trend compare to each groups of female. The result of this study, it was found that female rated higher intra-individual consistency and definition in the two times evaluations than male and among the semantic differential scales'consistency differ depending on style and gender. It is believed that the result of this study is helpful clothing image evaluation, and clothing image selection tendency.

  • 본 연구는 정서 자극 유형 중 일상생활과 가장 유사한 정서 경험을 유발하는 자연주의적 자극인 영상 자극을 활용하여 정서표상의 유사성과 개인 간 반응 일관성을 살펴보기 위해 수행되었다. 이를 위해 다차원척도법을 실시하여 영상 자극이 핵심정서 차원에 위치하는지 확인하고, 참가자 간 분류분석을 사용하여 영상들이 정서유형 별로 구분이 잘 이루어지는지, 영상 자극에 대한 참가자들의 정서표상이 일관적인지 검증하였다. 또한 참가자간 상관분석을 통해 각 영상 자극에 대한 정서표상이 참가자들간 유사한지 추가적으로 확인하였다. 다차원척도법 결과, 정서유발 영상들이 정서가 차원에서 유의하게 구분되어 Russell(1980)의 핵심정서차원을 부분적으로 지지하였다. 분류분석 결과, 각 영상이 정서유형에 따라 잘 분류되고 예측되었다. 마지막으로, 참가자간 상관분석을 통해 정서 반응 일관성이 각 영상의 정서유형에 따라 다르게 나타남을 확인하였다. 본 연구는 영상 자극에 대한 정서표상과 정서 반응 일관성이 정서 유형에 따라 차이가 있음을 시사한다.

  • The purpose of this study is to analyze the structural relationship among self-leadership, grit, and performance.Specifically, self-leadership was selected as an independent variable, two dimensions of grit were selected as mediator variables, and performance was selected as a dependent variable. This structural equation model is based on previous studies.The subjects of this study were middle and high school Taekwondo players, and the survey was collected using the online survey system KSDC (Korean Social-Science Data Center). The sampling method was a non-probability sampling method, convenience sampling method.A total of 367 copies were collected through this process, and 355 copies were used as the final valid samples after excluding the insincere data.Data processing was done with SPSS 23 for frequency analysis, exploratory factor analysis and reliability analysis. Also, AMOS 21 was used for confirmatory factor analysis and structural equation model analysis. The results of the analysis are as follows: First, self-leadership had a positive effect on bothi interest consistency grit and effort persistence grit. Second, it was found that both interest consistency grit and effort persistence grit have a positive effect on performance.Third,self-leadership had a positive effect on performance.

  • A database called Home Location Register(HLR) plays a major role in location management in mobile cellular networks. The objectives of this paper are to identify the problems of the current HLR system through rigorous analysis, to suggest solutions to them. The current HLR backup method is a process of simply writing the changed memory SLD block to disk, which has a problem in maintaining database consistency. Since information change and backup are performed separately by separate processes, there is a risk of information inconsistency when an error restart occurs. To solve this problem, a transaction concept was introduced for subscriber-related operation functions and a recovery method through logging and checkpointing was introduced. The subscriber related functions of tasks terminated normally by the suggested process are recovered with consistency even after system restarts. Performance is also not affected seriously because disk tasks for log occur with only subscriber related functions.
