This paper expanded the usefulness of technology relation analysis by applying to R&D activities of Korea Gas Corporation (Kogas) at the corporate level. Technology relation analysis has been applied to assessment of R&D investments in telecommunication and construction industries in Korea. As empirical findings, technology map and technology spillover matrix of Kogas have been derived by technology similarity analysis. It has bee found that various useful information for R&D assessment could be acquired from the technology relation analysis at the corporate level.

Generally, singularity analysis of 6-DOF parallerl manipulators is very difficult and, as result, velocity relation has many uncertainties. In this paper, an alternative method using the local structurizatioin method(LSM) for the analysis of singular configuraions is presented. With LSM, the velocity relation can be represented in a simple form, and the result is totally equivalent to the conventional velocity relation. The velocity relation suggested in this paper gives a closed-form solution of singularities.

The purpose of this study was to identify the importance of salesperson selling behavior such as salesperson's orientation, similarity with customers and expertise as well as the relationship benefits of salesperson. A total of 400 questionnaires were distributed to adults in Daegu-Kyongbuk area and 335 questionnaires were collected(84%) and 314 samples were used for the statistical analysis. The primary methods of the statistical analysis were factor analysis, confirmatory factor analysis, correlation and path analysis using LISREL 8. The results are as follows: First, clothings salesperson's customer-orientation(p < .10), expertise, similarity (p< .10) and salesperson's functional, social benefits showed positive relation with customer satisfaction. And salesperson's selling-orientation influenced customer satisfaction of salesperson negatively. In addition customer satisfaction of salesperson showed positive relation with salesperson loyalty and satisfaction of the stores. Second, the salesperson loyalty showed positive relation with store loyalty and word-of-mouth but showed negative relation with post-purchase information search. Customer satisfaction of stores showed negative relation with post-purchase information search but no meaningful relation with store loyalty and word-of-mouth.

Cyber-attacks emerge in a more intelligent way, and various security technologies are applied to respond to such attacks. Still, more and more people agree that individual response to each intelligent infringement attack has a fundamental limit. Accordingly, the cyber threat intelligence analysis technology is drawing attention in analyzing the attacker group, interpreting the attack trend, and obtaining decision making information by collecting a large quantity of cyber-attack information and performing relation analysis. In this study, we proposed relation analysis factors and developed a system for establishing cyber threat intelligence, based on malicious code as a key means of cyber-attacks. As a result of collecting more than 36 million kinds of infringement information and conducting relation analysis, various implications that cannot be obtained by simple searches were derived. We expect actionable intelligence to be established in the true sense of the word if relation analysis logic is developed later.

본 연구의 목적은 허쉬(Hirschi)의 사회유대이론과 학교적응 영역의 기존연구를 토대로 청소년의 학교적응에 관한 사회적 관계 모델을 제시하고 검증하는 것이다. 사회적 관계 모델에는 부모관계변인, 친구관계변인, 교사관계변인이 포함되었다. 연구 대상은 인문계 고등학교 재학생 351명과 전국 쉼터에 머무르고 있는 청소년 143명으로 총 494명이었다. 자료분석방법으로는 기술통계, 상관관계분석, 중다회귀분석이 사용되었다. 분석결과, 청소년의 학교적응에 관한 사회적 관계 모델이 청소년의 전반적 적응과 학업적 적응(성적)을 설명하는 데 유의미하다는 것이 밝혀졌다. 구체적으로는, 부모와의 관계가 좋을수록, 친구와의 관계가 좋을수록, 교사와의 관계가 좋을수록 청소년의 학교적응도가 높아지는 것으로 나타났으며, 이 중 가장 영향력있는 변인은 교사관계 변인이었다. 이러한 결과를 기초로 본 연구는 청소년의 학교적응을 높이는 방법으로서 교사 친구 부모와의 관계를 긍정적으로 변화시키기 위한 실제적 방안을 제시하였다.

The purpose of this study is to verify career maturity, achievement goal, learning attitude and academic achievement relation with subjects-related career education of middle school students. To achieve these aims, this study used SELS(Seoul education longitudinal study) of Seoul Education Research & Information Institute. Also, analysis as well as descriptive statistics calculation on average, deviation, skewness and kurtosis of variable factor and calculated characteristic item and degree of reliability(Cronbach ${\alpha}$). For goodness of fit test, this study used TLI(Tucker-Lewis index) and RMSEA(Root mean square error of approximation). To achieve the ultimate objects, this study used LMA(latent mean analysis) for analysis of difference career maturity, achievement goal, learning attitude and academic achievement relation with subjects-related career education in middle school students. The results are as follows. First, experience relation with subjects-related career education were influenced on career maturity with career cognition. Second, experience relation with subjects-related career education were influenced on achievement goal, learning attitude, and larger than career maturity and academic achievement. Third, experience relation with subjects-related career education were influenced on middle school students more than inexperienced relation with subjects-related career education.

의존관계 분석은 문장의 어절 간에 의존소-지배소를 결정하는 작업이다. 용언은 문형 및 하위범주화 정보의 선택제약에 의해 다른 어절과의 의존관계를 형성한다. 본 논문은 형태소 분석 단계에서 동형이의어 분별된 용언의 문형을 이용하여 용언의 의존관계를 분석하는 방법을 제안한다. 특히, 형태소분석 단계에서 품사 및 동형이의어 태깅을 위해 사용하는 단계별 전이모델의 학습사전을 재활용하여 {명사+격조사, 용언} 간의 의존관계를 확정하는 방안을 제안하고 그의 정확률 및 영향을 분석한다. 동형이의어가 부착되고 의존관계로 변경된 21개의 세종구문분석말뭉치를 이용하여 실험한 결과, 동형이의어 분별된 의존관계 분석 정확률이 80.38%로, 동형이의어가 분별되지 않은 의존관계분석에 비해 0.42%의 정확률 향상이 있었으며, 유의수준 1%의 검정통계량 Z는 ${\mid}Z{\mid}=4.63{\geq}z_{0.01}=2.33$으로 동형이의어 분별이 의존관계 분석에 영향이 있음을 보였다. 또한, 단계별 전이모델이 의존관계 분석 정확률에 약 7.14% 영향을 미치는 것을 알 수 있었다.

In this Paper, we analyzed the relative importance of multiple sources and their effects on innovative activities. Through factor analysis, we found 5 sources of innovative activities; university/laboratory source, within firm source, general information source, vertical/competitive relation source, and horizontal relation source. Through regression analysis, we found that (1) 'within firm source' is the most important source on innovative activities, (2) from inputs' point of view, the more 'vertical/competitive relation source' is, the less innovative activities we, (3) from outputs' point of view, innovations are more activated when 'university/laboratory source' is abundant. but, they are less activated when 'general information source' and 'vertical/competitive relation source' is abundant, and (4) according to firm size and innovation stages(newproduct innovation, upgraded product innovation, and process innovation), the effect of sources on innovative activities is different.

본 논문에서는 퍼지 관계를 이용하여 한국 음식과 해당 음식의 맛을 표현하는 관능 형용사를 분석하였다. 이를 위하여 음식의 맛뿐만 아니라 냄새 등도 표현할 수 있는 87개의 한국어 형용사를 선별하고, 20명의 실험자를 대상으로 51개의 한국음식들을 시식하게 하고 해당 음식 맛 표현에 적합한 형용사를 선택하게 하는 관능 평가를 실시하였다. 이렇게 얻어진 결과로 부터 퍼지 관계를 구성하고 음식과 형용사의 특성을 분석하였다. 또한 퍼지관계 합성을 통하여 음식과 음식 사이의, 또는 형용사와 형용사 사이의 퍼지허용(호환)관계를 구성하였으며, 이들 관계의 퍼지 완전 ${\alpha}$-커버(fuzzy complete ${\alpha}$-cover)로 부터 음식과 형용사의 분류체계를 탐색할 수 있었다. 본 논문의 퍼지 관계를 이용한 방법은 비단 음식과 맛 표현 뿐만 아니라 후각과 촉각과 같은 관능 형용사를 분석하는데 활용될 것을 기대된다.

This study empirically investigates the effect of self presentation on SNS to interpersonal relation and quality of life. Especially, we performed exploratory analysis that how SNS affect to quality of life and wether the change of interpersonal relation is mediating effect to quality of life and intention to use. And we also suggest that the capability of communication would be a moderator. In the results, firstly, the using SNS has significantly positive effect on the change of interpersonal relation. And it as mediation variable can positive impact on the relationship between the using SNS, quality of life, and Intention to use. In the moderating analysis, SNS users who responded higher communication capability have significantly more higher effect on the change of interpersonal relation and quality of life. Secondly, the change of interpersonal relation after use of SNS as a mediation variable serves to enhance the relationship between the use of SNS and the quality of life in the positive direction.
