Describes the impact of electronic communication media on communications among reference librarians and explores the usabilities of the mailing list as an efficient means of reference services. Out of messages made to the library mailing list over the one-year period of the study, 594 postings dealing with reference questions were examined. The types of questions and the rate of responses were analyzed and some limitations to the implementation of the malling list on answering the reference questions were discussed.

본 논문은 국소문맥을 사용하여 만들어진 Decision List를 통해 단어의 형태적 중의성을 제거하는 방법을 기술한다. 최초 종자 연어(Seed Collocation)로 1차 Decision List를 만들어 실험 말뭉치에 적용하고 태깅된 결과를 자가 학습하는 반복과정에 의해 Decision List의 수행능력을 향상시킨다. 이 방법은 단어의 형태적 중의성 제거에 일정 거리의 연어가 가장 큰 영향을 끼친다는 직관에 바탕을 두며 사람의 추가적인 교정을 필요로 하지 않는 비교사 방식(대량의 원시 말뭉치에 기반한)에 의해 수행한다. 학습을 통해 얻어진 Decision List는 연세대 형태소 분석기인 MORANY의 형태소 분석 결과에 적용되어 태깅시 성능을 향상시킨다. 실험 말뭉치에 있는 중의성을 가진 12개의 단어들에 본 알고리즘을 적용하여 긍정적인 결과(90.61%)를 얻었다. 은닉 마르코프 모델의 바이그램(bigram) 모델과 비교하기 위하여 '들었다' 동사만을 가지고 실험하였는데 바이그램 모델의 태깅결과(72.61%)보다 뛰어난 결과(94.25%)를 얻어서 본 모델이 형태적 중의성 해소에 유용함을 확인하였다.

The web server is configured to display the list of files contained in this directory. This is not recommended because the directory may contain files that are not normally exposed through links on the web site. The directory list have some serious vulnerability to show internal files and directory to outsider attackers. Therefore, the proposed countermeasure of directory list is presented to prevent unnecessary valuable information from outsider attackers.

Kano model has been widely used to identify and classify customer attributes of a product or a service. The first step of Kano model application is the derivation of customer attributes, and brainstorming has been used conventionally for the purpose. A typical advantage of brainstorming is to get many ideas in a relatively short period, but the practicability of the derived ideas are known to be not so good. The derivation of good and practical ideas is important for the successful use of Kano model. Wish list, bug list and forced connection method as well as brainstorming were applied to PMP(Portable Multimedia Player) in order to derive customer attributes. To compare the idea generation methods, the derived attributes are classified and compared using Kano model.

This list contains all the species of mushrooms recorded in Korea and the Korean name for the species. Since the Korean Society of Mycology reported the mushroom name list of 588 species from 190 genera in 1978 for a unification of Korean name for mushrooms many papers and illustrated books have added the name of recorded mushrooms to the list. However, we have been confused with the scientific name and the Korean name for the fungi due to a inappropriate arrangement and an incomplete classification system of Korean mushrooms. Therefore, I rearranged 885 species from 261 genera, which have been reporeted in Korea, based on the recently published documents such as Ainsworth et al. (1973), Singer (1986) and Imazeki and Hongo (1987 and 1988).

Nowadays, recommender systems suggest lists of items to users considering not only accuracy but also diversity and novelty. However, suggesting the most diverse list of items to all users is not always acceptable, since different users prefer and/or tolerate different degree of diversity. Hence suggesting a personalized list with a diversity degree considering each user preference would improve the efficiency of recommender systems. The main contribution and novelty of this study is to tune the diversity degree of the recommendation list based on the users' variety-seeking feature, which ultimately leads to users' satisfaction. The proposed approach considers the similarity of users' desire diversity as a new parameter in addition to the usual similarity of users in the state-of-the-art collaborative filtering algorithm. Experimental results show that the proposed approach improves the personal diversity criterion comparing to the closest method in the literature, without decreasing accuracy.

지능형 전력망인 Smart Grid의 등장으로 미국, 일본 등의 국가는 Smart Grid 시장을 선점하기 위해 노력하고 있다. 한국 또한 경쟁국으로서 G20 정상회의에서 Smart Grid 시범 단지를 선보이려고 준비 중에 있다. Smart Grid의 발전에 기본적인 전력기기와 IT기기의 융합 모델인 전력IT기기의 연구가 진행되고 있고, 단일 전력 기기일 때와는 달리 IT 기기의 특성에 따른 보안 문제에 노출되어 보안에 대한 연구가 필수적이다. 본 논문에서는 Smart Grid에 사용되는 전력 IT 기기에 적용 할 수 있는 보안 방법인 BlackList 설정을 연구하여 Smart Grid 시대의 발전에 기여 할 것이다.

The suborder Symphyta comprises more than 8,000 described species worldwide, of which about 4,400 extant species are recorded from the Eastern Palaearctic. Symphyta can be easily distinguished from the suborder Apocrita by the abdomen, which is broadly joined to the thorax. The larvae of most species feed on herbaceous to woody. A list of the 418 described species of Symphyta in Korea is presented. The list is in taxonomic sequence by superfamily, family, subfamily and genus and includes 116 genera in 22 subfamilies, 12 families, and seven superfamilies. We provide the page reference of the original description of every species and genus listed, Korean name, host records, and all Korean records. The list also provides the distribution of all the species by country.

We make advances towards a structural characterisation of the signed graphs H for which the list switch H-colouring problem List-S-Hom(H) can be solved in polynomial time. We conjecture two different characterisations, the second refining the first, in the case that the graph H can be switched to a graph in which every negative edge is also positive. Using a recent proof of the first characterisations for reflexive signed graphs, by Bok et. al., we prove the second characterisation for reflexive signed graphs. We also provide several tools for reducing the problem to the bipartite case, and prove a full complexity dichotomy for a related problem.
