Despite limited success, today's information retrieval (IR) systems are not intelligent or reliable. IR systems return poor search results when users formulate their information needs into incomplete or ambiguous queries (i.e., weak queries). Therefore, one of the main challenges in modern IR research is to provide consistent results across all queries by improving the performance on weak queries. However, existing IR approaches such as query expansion are not overly effective because they make little effort to analyze and exploit the meanings of the queries. Furthermore, word sense disambiguation approaches, which rely on textual context, are ineffective against weak queries that are typically short. Motivated by the demand for a robust IR system that can consistently provide highly accurate results, the proposed study implemented a novel topic detection that leveraged both the language model and structural knowledge of Wikipedia and systematically evaluated the effect of query disambiguation and topic-based retrieval approaches on TREC collections. The results not only confirm the effectiveness of the proposed topic detection and topic-based retrieval approaches but also demonstrate that query disambiguation does not improve IR as expected.

This exploratory study investigated the software programs utilized by clinical dietitians and their perceptions on the use of information technology. The study focused on the use of specialized software for dietetics, general software for any office use and the Internet. A self-administered survey was used to collect data from clinical dietitians identified in the Kentucky Dietetic Association Directory 2003-2004. The survey was conducted in March through April, 2004. A total of 22 responses were collected, which yielded a response rate of $68\%$. Findings suggest that computer use has become a routine for optimal clinical practice ; major specialized software programs are used for nutrition assessment, nutrition analysis and menu development. Use of specialized software appears to be unassociated with dietitians' age and years of experience ; however, the associations are indicated between use of specialized software and education level as well as their specialty ; word processing and spreadsheet are the major general software used. Internet is used mainly for information search and communication. Respondents perceived that overall work efficiency and productivity significantly increased with computer use. The complexity of software is the major barrier encountered so training is the most needed support by the department. Strategic promotion on the use of specialized software should be targeted to the management team of the hospitals/facilities.

In the Russian 'spirituality' which played an important role in realization of 'abstraction' in modern arts, the three elements of Universalism - Oriental thoughts, Universal ideas, and Froebelian influence - can be found with no difficulty. More notable is the fact that, along with theosophy, the emergence of modern existential thoughts such as Bergson, Schopenhauer, Nietzsche is a new search and a new recognition of nature and human as views of panentheism and humanism, essentially of Humane and Divine. Therefore, it goes without saying that the thoughts constituting the Suprematism or Constructivism in Russia are, in a word, implicit in the existential humanistic ideas of Panpneumatism or Panentheism that is explained as the nature of Russian religious ideas. Furthermore, which is not only Suprematist's metaphysical principle but also the expression of universal thoughts; interestingly, which is closely akin to several Oriental mystic ideas including Taoist thoughts, as well as the contents of Universalism including mystic Christianity, by extension, which ideas and principles have a remarkable resemblance with thoughts and principles of Froebel.

In this paper, we propose a dynamic document classification method which breaks away from existing document classification method with artificial categorization rules focusing on suppliers and has changing categorization rules according to users' needs or social trends. The core of this dynamic document classification method lies in the fact that it creates classification criteria real-time by using topic modeling techniques without standardized category rules, which does not force users to use unnecessary frames. In addition, it can also search the details through the relevance analysis by calculating the relationship between the words that is difficult to grasp by word frequency alone. Rather than for logical and systematic documents, this method proposed can be used more effectively for situation analysis and retrieving information of unstructured data which do not fit the category of existing classification such as VOC (Voice Of Customer), SNS and customer reviews of Internet shopping malls and it can react to users' needs flexibly. In addition, it has no process of selecting the classification rules by the suppliers and in case there is a misclassification, it requires no manual work, which reduces unnecessary workload.

Most recent web search engines perform effective keyword-based multimedia contents retrieval by investigating keywords associated with multimedia contents on the Web and comparing them with query keywords. On the other hand, most music and compilation albums provide professional artwork as cover art that will be displayed when the music is played. If the cover art is not available, then the music player just displays some dummy or random images, but this has been a source of dissatisfaction. In this paper, in order to automatically create cover art that is matched with music contents, we propose a music album cover art creation scheme based on music contents analysis and result synthesis. We first (i) analyze music contents and their lyrics and extract representative keywords, (ii) expand the keywords using WordNet and generate various queries, (iii) retrieve related images from the Web using those queries, and finally (iv) synthesize them according to the user preference for album cover art. To show the effectiveness of our scheme, we developed a prototype system and reported some results.

In this paper, newspaper articles were collected through '5.18' keyword search results and the news corpus was constructed from the collected data. In the articles of local newspapers 'Honam' and 'Yeongnam', the ideological differences regarding '5.18' were investigated. The ideological differences of local newspaper discourse through objective figures was analyzed.. The subjects of the newspaper articles, the frequency of nouns and predicates were analyzed. The use and meaning of the intended vocabulary were examined. As a result of analyzing the title of the newspaper article, the discourse written in 'Honam' emphasized the necessity of re - recognition of 5.18. In both regions, the word "Gwangju" is often used. However, 'Gwangju' in 'Honam' newspaper means spiritual space, not physical space. In Honam regional newspapers, there are many vocabularies describing the events such as 'shoot' and 'fire', this calls for recollection and memory of '5.18'. In the analysis of newspaper discourse, the analysis of the contrast between the local newspapers was very insignificant, but, this study was conducted to analyze the discourse among local newspapers.

Objectives The purpose of this research is to comprehensively analyze about Jowiseungcheong-tang (Diàowèishēngqīng-tāng). This herbal medicine is widely used to treat obesity and metabolic disease. Methods We used 3 search terms, 'Jowiseungcheong-tang', 'Jowiseungcheong-tang plus obesity' and 'Jowiseungcheong-tang plus metabolic disease' in Korean word via 5 domestic databases. Therefore, 8 laboratory experiments and 4 clinical researches were chosen. Results Jowiseungcheong-tang (Diàowèishēngqīng-tāng) was identified as a herbal medicine for obesity and related metabolic disease. In plasma level of lipid, leptin, inflammatory material were decreased in laboratory experiments. Weight loss and symptom relief were reported in clinical research. Conclusions Definite information about laboratory experiment was showed, specifically suitable index and numerical value. In clinical research, although Jowiseungcheong-tang (Diàowèishēngqīng-tāng) is widely used for obesity and metabolic disease, the number of reported thesis and patient were pretty a few. Also, diagnosis methods were also scanty. Multi-institutional clinical trial should be progressed.

At EUROCRYPT 2015, Todo proposed a new technique named division property, and it is a powerful technique to find integral distinguishers. The original division property is also named word-based division property. Later, Todo and Morii once again proposed a new technique named the bit-based division property at FSE 2016 and find more rounds integral distinguisher for SIMON-32. There are two basic approaches currently being adopted in researches under the bit-based division property. One is conventional bit-based division property (CBDP), the other is bit-based division property using three-subset (BDPT). Particularly, BDPT is more powerful than CBDP. In this paper, we use Boolean Satisfiability Problem (SAT)-aided cryptanalysis to search integral distinguishers. We conduct experiments on SIMON-32/-48/-64/-96, SIMON (102)-32/-48/-64, SIMECK-32/-48/-64, LBlock, GIFT and Khudra to prove the efficiency of our method. For SIMON (102)-32/-48/-64, we can determine some bits are odd, while these bits can only be determined as constant in the previous result. For GIFT, more balanced (zero-sum) bits can be found. For LBlock, we can find some other new integral distinguishers. For Khudra, we obtain two 9-round integral distinguishers. For other ciphers, we can find the same integral distinguishers as before.

Purpose: This study aimed to provide basic data to identify the current status of use of maxillofacial prosthesis across the world and discuss its application and research directions in Korea. Methods: Existing literature (study period, 2010 to 2020) from international studies was collected from PsycINFO, CINAHL, and PubMed, whereas domestic studies were searched using KISS and RISS. Maxillofacial prosthesis was used as the search word. A total of three foreign and two domestic articles were searched, and as a result, a total of 12 documents were selected for analysis. Results: A total of 3,311 studies were searched in this study. Among them, 3,253 articles contained in duplicate inspection and exclusion criteria were removed, and 12 articles were selected by removing literature that did not meet the research criteria through title and green and text reviews. Finally, two researchers selected the final 12 articles through handwritten searches. Eleven of them were case studies, and the remaining one was a descriptive study. Conclusion: This study identified the current status of studies that implemented maxillofacial prosthesis, published from January 2010 to January 2020. Facial prosthetics improve the quality of life of patients by restoring defects that appear on different types of mouth and face and promote both function and aesthetics. Therefore, they can be used to treat various conditions and have a positive impact on the future.
