In the field of oriental medicine, many researchers head for the aim of standardization. To achieve this aim, oriental medical researchers have been carried out experimental research, statistical research, clinical research, philological research, etc., and, have published their results to journals. But, the declaration of Roman name of herbal formula is not united each other, on several article. So, we should prepare database to search in domestic and overseas, and should consider compatibility of internationally used search system. Also, it is need to use appropriate roman letters in oriental medical terms for people can use easily. We inquired the type of roman letters in the name of formula of article that were carried oriental medical journal, to find out appropriate roman letters and to the demands of the times. There were many cases that Korean name of formula is not correspond to the declaration of Korea roman letters. Also, the declaration of roman letters for preparation like as tang(湯), san(散), hwan(丸) etc. are not standardized. To facilitate making database and forming search system, now we suggest that we can standardize the declaration of Korea roman letters by using of Hangul(한글) word processor's toolbar which has transformation of roman letters.

This study analyzed risk perception and risk reduction behaviors of male and female college students in their twenties who purchased fashion products in internet shopping malls. It also investigated the relationship between risk perception and risk reduction behavior as well as the ways in which groups, categorized by risk perception, differed in their risk reduction behaviors. The results of this study were as follows: first, seven factors of risk perception were identified. These were product quality, shipping, product image, payment, economic feasibility, fear of other people's reactions, and size. Six types of risk reduction behavior were also identified. These were product comparison, word-of-mouth information search, price search, preference for name-brand, service comparison, and referring to experiences. Next, a correlational analysis of the factors of risk perception and those of risk reduction behavior showed several patterns. The highest positive correlation was between economic risk perception and product comparison behavior. In addition, shipping risk perception was positively correlated with service comparison behavior and product quality and product image had a positive correlation with word-of-mouth information search behavior. Third, customers of internet shopping malls could be categorized into three groups: shipping risk perception group, high risk perception group, and product quality risk perception group. The groups were shown by factor analysis to be significantly different to each other. Finally, risk reduction behavior was investigated according to the different groups of risk perception of the internet shopping malls and the results showed significant differences among groups.

사람들은 월드 와이드 웹 상에서 사용자가 원하는 정보를 검색하는 여러 알고리즘들을 구현해 왔다. 이렇게 구현된 검색 알고리즘 중 가장 좋은 기술을 가지고 있는 곳은 페이지랭크(PageRank)방식의 구글이다. 하지만 외부에서 참조하는 링크가 많은 문서를 가지고 있는 문서 즉, 대중들이 관심을 가지는 문서를 상위에 보여주는 페이지랭크 방식으론 사용자가 원하는 문서를 찾아서 제공하지 못할 수 있다. 개인에게 가치가 있는 문서를 찾기보다 대중에게 가치가 있는 문서를 찾기 때문이다. 이러한 문제를 해결하기 위하여 본 논문에서는 어휘의 의미를 정확히 표현하고 있는 워드넷을 이용하여 사용자 질의 이력 정보를 분석하여 현재 질의를 확장한 개인적 가치와 페이지 랭크지수를 이용한 대중적 가치를 모두 고려한 방법을 제안한다. 실험결과 제안한 방법은 상위 30개의 검색결과 중 평균 약 60% 결과들에 대해 만족하는 것으로 나타났으며, 구글 검색 결과에 비해 평균 약 14% 향상된 만족도를 나타내었다.

Purpose: The purpose of this paper is to present implications by analyzing research trends on smart factories by text analysis and visual analysis(Comprehensive/ Fields / Years-based) which are big data analyses, by collecting data based on previous studies on smart factories. Methods: For the collection of analysis data, deep learning was used in the integrated search on the Academic Research Information Service (www.riss.kr) to search for "SMART FACTORY" and "Smart Factory" as search terms, and the titles and Korean abstracts were scrapped out of the extracted paper and they are organize into EXCEL. For the final step, 739 papers derived were analyzed using the Rx64 4.0.2 program and Rstudio using text mining, one of the big data analysis techniques, and Word Cloud for visualization. Results: The results of this study are as follows; Smart factory research slowed down from 2005 to 2014, but until 2019, research increased rapidly. According to the analysis by fields, smart factories were studied in the order of engineering, social science, and complex science. There were many 'engineering' fields in the early stages of smart factories, and research was expanded to 'social science'. In particular, since 2015, it has been studied in various disciplines such as 'complex studies'. Overall, in keyword analysis, the keywords such as 'technology', 'data', and 'analysis' are most likely to appear, and it was analyzed that there were some differences by fields and years. Conclusion: Government support and expert support for smart factories should be activated, and researches on technology-based strategies are needed. In the future, it is necessary to take various approaches to smart factories. If researches are conducted in consideration of the environment or energy, it is judged that bigger implications can be presented.

포털 사이트의 실시간 검색어는 현재 관심이 급상승하고 있는 이슈를 보여주기 위해 주로 검색횟수가 많은 순서에 따라 몇 초 간격으로 제공되고 있다. 그렇지만 너무 짧은 시간 내에 순위가 바뀌는 실시간 검색어의 특성 때문에 하루의 핵심 이슈를 비켜가는 문제가 발생한다. 본 논문에서 이러한 문제를 보완하기 위해 검색어들 사이의 연관 분석을 통하여 검색어들이 관련된 핵심 이슈를 도출하는 방법을 제안하고자 한다. 이를 위해 먼저 실시간 검색어를 순위와 상대적 관심도를 기반으로 점수화하여 집단별 기술통계를 통해 최상위 10개의 검색어를 도출한다. 그 다음으로 지지도와 신뢰도를 기반으로 연관 규칙을 추출하고 이를 가시화하는 그래프 결과를 바탕으로 핵심 이슈를 선정한다. 실험 결과는 단일 최상위 실시간 검색어보다 연관분석을 통해 높은 점수로 선정된 핵심 이슈가 더 큰 의미를 갖는다는 것을 보여준다.

최근 논문 표절 논란과 지능형 텍스트 검색서비스에 대한 관심이 증가하면서 문장 유사도 측정의 필요성이 증가하고 있다. n-gram, 편집거리, LSA 등 기존의 다양한 방향으로 선행 연구가 있었지만 각 기법마다 장단점이 존재한다. 본 논문에서는 집합 기반 POI 검색 기법을 이용한 새로운 방향의 문장 유사도 측정 기법을 제안한다. 집합 기반 POI 검색 기법은 하드매칭에 비해 단어의 도치, 누락, 삽입, 변경에 현저한 성능 향상을 보인다. 이 기법을 이용하면 보다 정확하고 빠른 문장 유사도 측정이 가능하다. 제안하는 기법은 기존 집합 기반 POI 검색 기법의 데이터 로딩 알고리즘과 텍스트 검색 알고리즘을 변형하고 어절 연산 알고리즘을 추가하여 두 문장의 유사도를 백분율로 표현한다. 실험을 통해 본 논문에서 제시하는 기법이 정확도와 속도에서 n-gram과 기존 집합 기반 POI 검색 기법에 비해 우수함을 확인하였다.

The purpose of this paper is to investigate the distribution of /ju/ in British English, especially after the coronal sonorants /n, l, /r/. The sequence /ju/ is related with vowels such as /u/, /ʊ/, and /ʊ/, and has occasioned a variety of conflicting analyses or suggestions. One of those is in which context /j/ is deleted if we suppose that the underlying form is /ju/. The context differs according to the dialect we deal with. In British English, it is known that /j/ is deleted always after /r/, and usually after /l/ when it occurs in an unstressed word-medial syllable. To check this well-known fact I searched OED Online (the 2nd Edition, 1989) for those words which contain /n, l, r/ + /ju, jʊ, u, ʊ, (j)u, (j)ʊ/ in their pronunciations, using the search engine provided by OED Online. After removing some unnecessary words, I classified the collected words into several groups according to the preceding sonorant consonants, the positions, and the presence (or absence) of the stress, of the syllable where /ju/ occurs. The results are as follows: 1) the deletion of /j/ depends on the sonorant consonant which /ju/ follows, the position where it occurs, and the presence of the stress which /ju/ bears; 2) though the influence of the sonorant consonants is strong, the position and stress also have non-trivial effect on the deletion of /j/, that is, the word-initial syllable and the stressed syllable prefer the deletion of /j/, and word-medial and unstressed syllable usually retain /j/; 3) the stress and position factors play their own roles even in the context where the effect of /n, l, r/ is dominant.

Together with soaring interest on Big Data, now there are vigorous reports that unearth various social values lying underneath those data from a number of application areas. Among those reports many are using such data as Internet search histories from Google site, social relationships from Facebook, and transactional or locational traces collected from various ubiquitous devices. Many of those researches, however, are conducted based on the data sets that are accumulated over the North American and European areas, which means that direct interpretation and application of social values exhibited by those researches to the other areas like Korea can be a disturbing task. This research has started from a validation study against Korean environment of the former paper which says an investment strategy that exploits up and down of Google search volume on a carefully selected set of terms shows high market performance. A huge difference between North American and Korean environment can be eye witnessed via the distinction in profit rates that are exhibited by the corresponding set of search terms. Two sets of search terms actually presented low correlation in their profit rates over two financial markets. Even in an experiment which compares the profit rates with two different investment periods with the same set of search terms showed no such meaningful result that outperforms the market average. With all these results, we cautiously conclude that establishing an investment strategy that exploits Internet search volume over a specified word set needs more conscious approach.

In order to overcome the problem that outdoor and indoor spatial information service are separately utilized, an integration service system of spatial information that is linked from outdoor to indoor has been implemented. As a result of the study, "0001.xml" corresponding to the file index key value, which is the service connection information in the building information of the destination, was extracted from the prototype verification of the system, the search word of 'Kim AB' was transmitted to the indoor map server and converted from the outdoor map service to the indoor map service through confirmation of the navigation service connected information, using service linkage information and search words of the indoor map service was confirmed that the route was displayed from the entrance of the building to the destination in the building through the linkage search DB (Database) table and the search query. Therefore, through this study was examined the possibility of linking indoor and outdoor DB through vector spatial information integration service system. The indoor map and the map engine were implemented based on the same vector map format as the outdoor map engine, it was confirmed that the connectivity of the map engine can be applied.
