The purpose of this study is to examine whether the information resources referenced by human indexers during indexing process are effective on Text Categorization. More specifically, information resources from bibliographic information as well as full text information were explored in the context of a typical scientific journal article data set. The experiment results pointed out that information resources such as citation, source title, and title were not significantly different with full text. Whereas keyword was found to be significantly different with full text. The findings of this study identify that information resources referenced by human indexers can be considered good candidates for text categorization for automatic subject term assignment.

This paper investigates the role of perceived income hierarchy and political affiliation in individual attitudes toward environmental protection. Estimation results show that rises in perceived income hierarchy increase the possibility of agreement to an increase in taxes to prevent environmental pollution in general, but not linearly increase it. As individuals are more satisfied with the financial situation of their household, they are more likely to agree to an increase in taxes. These results imply that individual attitudes toward environmental protection can be deteriorated even though average household income level increases, if either the degree of financial satisfaction decreases or income inequality worsens. We find that there is no difference between the liberals and the conservatives on the likelihood of paying additional tax to prevent environmental pollution. This result differs from the cases of Western society, which indicate that the liberals are more likely to pay for environmental protection.

This paper focused on fading out the factors of design innovation. Based on the previous studies, several factors were extracted to be tested by Delphi method among 15 experts in the design area. Delphi test showed a convergent result after the second round of questioning. Design mind of managers was conceived as the most important factor among those tested. On the base of importance, capability of design company was the second and industrial design demand was the third. Even though design manpower, design infrastructure and innovation network were ranked below the 4th factors, the absolute differences between high ranked factors and low ranked ones were not much wide. So. relatively low ranked factors were not negligible at all to get a desirable success in design innovation. This study provides some insights for the success of design innovation. First of all, design innovation could be achieved only when factors tested on this study upgraded simultaneously together. Desirable effect could not expected by a simple support such as logo design or kind of simple measure.

In this paper, an algorithm for a real-time automatic fingerprint identification system is proposed. The fingerprint feature volume is extracted by considering distinct and local characteristics(such as intensity and image quality difference etc.) in fingerprint images, which makes the algorithm properly adaptive to various image acquisitionj methods. Also the matching technique is designed to be invariant on rotation, scaling and translation (RST) changes while being capable of real-time processing. And the classification of fingerprints is performed based on the ridge flow and the relations among singular points such as cores and deltas. The developed fingerprint identification algorithm has been applied to various sets of fingerprint images such as one from NIST(National Institute of Standards and Technology, USA), a pressed fingerprint database constructed according to Korean population distributions in sex, ages and jobs, and a set of rolled-than-scanned fingerprint images. The overall performance of the algorithm has been analyzed and evaluated to the false rejection ratio of 0.07% while holding the false acceptance ratio of 0%.

This study investigates the effects of the operation of science activity program on scientific literacy focusing on science cultural literacy and core competencies for pre-service teachers. 255 pre-service teachers of K University participated, and the effects of the program were examined through a paired-sample t-test with one group pretest-posttest design for science cultural literacy. Only the post-test was conducted on core competency growth perception, and differences in growth perceptions by competency were compared using ANOVA. As a result of the study, the average of pre-service teachers was higher than the pre-test for science culture literacy, and this difference was statistically significant (p<.05). In the core competency growth perception, 70.6% of pre-service teachers reported growth in scientific communication ability, and as a result of the post-hoc test using LSD, it shows statistically significant growth compared to other competencies (p<.05). Through this, it was possible to confirm the educational value of the science activity program as a way to develop pre-service teachers' scientific literacy.

In order to provide with personalized recommendation service in context-awareness environment, the collected context data should be analyzed fast and the objective of user should be able to inferred effectively. But, the context collected from the mobile devices is not suitable for applying the existing inference algorithms as they are due to the omission or uncertainty of information and the efficient algorithms are required for mobile environment. In this paper, the behavior pattern was classified using naive bayes classification for minimize the loss caused by the omission or error of information. And pattern matching was used to effectively learn of the users inclination and infer the behavior purpose. The accuracy of the suggested inference model was evaluated by applying to the application recommendation service in the smart phones.

Since liberalization of overseas tour in 1989, the number of travel agencies and tourists increases rapidly. The role of tour conductors becomes more important element in tourist satisfaction, because they take charge of every detail of the overseas tour package from departure to arrival. The purpose of this study is to examine on the tour conductors' quality and competence on tourist satisfaction. Although the importance of quality factors were recognized differently by tourists and travel agents, the tour quality and competence of tour conductors are among those factors that influence most on tourists' satisfaction. So, tour conductors have to try to improve their quality and get the needs tourists want.

The visibility deteriorates in hazy weather and it is difficult to accurately recognize information captured by the camera. Research is being actively conducted to remove haze so that camera-based applications such as object localization/detection and lane recognition can operate normally even in hazy weather. In this paper, we propose a nonlinear model for depth map estimation through an extensive analysis that the difference between brightness and saturation in hazy image increases non-linearly with the depth of the image. The quantitative evaluation(MSE, SSIM, TMQI) shows that the proposed haze removal method based on the nonlinear model is superior to other state-of-the-art methods.

일반적으로 북한(北韓)의 노동력(勞動力)은 "양질의 저렴한" 것으로 인식되고 있다. 이러한 인식을 근거로 북한의 노동력에 남한의 자본과 기술을 결합시키고자 하는 대북투자사업(對北投資事業)은 활발히 추진(推進)되어 왔으며, 북한의 핵문제가 해결되는 경우 급속히 실행(實行)에 옮겨지게 될 것으로 보인다. 그러나 북한의 노동력이 과연 "양질의 저렴한" 것인가의 여부에 관하여 체계적(體系的)인 검토(檢討)는 이루어진 바가 없다. 본(本) 연구(硏究)에서는 북한의 노동력이 일반적으로 인식되고 있는 바와 같이 "양질의 저렴한" 것인지의 여부, 특히 '양질' 여부에 관하여 그 타당성(妥當性)을 북한 노동력의 교육수준(敎育水準), 작업규율(作業規律), 노동생산성(勞動生産性)의 세가지 측면에서 검토하여 보았다. 그 결과 교육수준이나 작업규율에 근거하여 북한의 노동력이 '양질'이라고 생각하는 것은 무리한 평가라는 결론에 도달하였으며, 가장 설득력이 있다고 여겨지는 노동생산성에 근거한 예상도 실증분석의 결과 타당성이 작은 것으로 나타났다. 자료의 한계상 본(本) 연구(硏究)에서 대상으로 한 것은 북한(北韓)의 평균적(平均的)인 노동력(勞動力)의 질(質)로서 실제 우리 기업이 고용하게 될 노동력의 질과 차이가 있을 수 있다. 그러나 본(本) 연구(硏究)에서 분석한 바와 같이 북한의 노동력이 '저렴'하지도 '양질'도 아닐 수 있으므로 대북투자사업(對北投資事業)의 보다 신중(愼重)한 검토(檢討) 및 대북투자사업시(對北投資事業時) 보다 효율적(效率的) 북한 노동력의 활용방안(活用方案)이 모색(摸索)되어야 할 것이다.

The purpose of this study was to identify issues in the family support center evaluation project by analyzing the differences in perception between evaluators and the family Support center using a meta-evaluation analysis model and seeking improvement alternatives. The results revealed a significant difference in group average: the evaluator group scored 4.21 out of 5 points, and the family center group scored 3.20 points. The improvement alternatives for each meta-evaluation item are as follows. In the evaluation environment, it is necessary to specify the purpose and utilization of evaluation within the guidelines of the Ministry of Gender Equality and Family. Evaluation input required the establishment of an evaluation support organization within the Korean Institute for Healthy Family. During the evaluation process, it was necessary to improve the use of the integrated family support information system and diversify communication channels. The evaluation results required the strengthening of follow-up education for family centers. In terms of evaluation utilization, it was necessary to strengthen support for various incentives and subcenters. This study provides implications for improving the evaluation system for various policy service delivery systems.
