인터넷 상에 많은 정보들이 발생하면서 검색 엔진은 사용자에게 필요한 흩어진 정보를 모아주는 중요한 역할을 하고 있다. 일부 검색 엔진에서는 검색어가 포함된 검색 결과 페이지뿐만 아니라 검색 결과 수도 함께 제공하고 있다. 구글 검색엔진에서 제공하는 검색 결과 수는 인터넷에서 해당 검색어에 대한 전체적인 추세를 파악하는데 활용될 수 있다. 본 논문에서는 구글 검색엔진에서 제공하는 검색결과 수를 효과적으로 관리할 수 있는 구글 검색엔진을 활용한 키워드 검색결과 수 관리 시스템을 설계하고 구현하고자 한다. 제안하는 시스템은 웹으로 작동하며 검색 에이전트, 저장 노드, 검색 노드로 구성되어 키워드 및 검색 결과 수를 관리하고 검색을 수행한다. 최종 검색 결과로는 검색 키워드, 검색 결과 수, 검색 결과 수를 활용하여 두 키워드의 거리를 계산하는 NGD(Normalized Google Distance)가 제공된다.

The paper aims to examine relationships between search-based sentiment and stock market reactions in Vietnam. This study constructs an internet search-based measure of sentiment and examines its relationship with Vietnamese stock market returns. The sentiment index is derived from Google Trends' Search Volume Index of financial and economic terms that Vietnamese searched from January 2011 to June 2018. Consistent with prediction from sentiment theories, the study documents significant short-term reversals across three major stock indices. The difference from previous literature is that Vietnam stock market absorbs the contemporaneous decline slower while the subsequent rebound happens within a day. The results of the study suggest that the sentiment-induced effect is mainly driven by pessimism. On the other hand, optimistic investors seem to delay in taking their investment action until the market corrects. The study proposes a unified explanation for our findings based on the overreaction hypothesis of the bearish group and the strategic delay of the optimistic group. The findings of the study contribute to the behavioral finance strand that studies the role of sentiment in emerging financial markets, where noise traders and limits to arbitrage are more obvious. They also encourage the continuous application of search data to explore other investor behaviors in securities markets.

정보의 체계적인 조직과 연계를 통해 검색의 정확률과 재현율을 제고하기 위해서는 전거레코드의 구축이 필수적이다. 특히, 저작의 집중과 탐색을 위한 기반으로서 전거레코드는 도서관 뿐 아니라 박물관, 기록관, 미술관 등 그 적용 범위가 더욱 확대되는 추세에 있다. 그러나 우리 도서관계에서는 지난 1999년에 KORMARC- 전거통제용을 제정한 이래, 국제적인 목록 환경과 국내 도서관계의 요구를 수용하면서 이에 대한 지속적인 관리와 개정작업을 수행하지 못하고 있다. 그 결과, 국내 도서관계에서 전거레코드를 구축하고 있는 도서관은 손에 꼽을 정도로 소수에 불과하며, 이러한 전거레코드의 부재는 검색의 효율을 저해하는 주요 원인으로 지목되고 있다. 이에 이 연구에서는 전거제어와 관련한 국제적인 목록 동향과 이러한 동향을 대폭 수용하여 개정한 MARC21을 상세히 분석한 다음, 우리 도서관계에 적용할 KORMARC - 전거통제용의 개정(안)을 제안하였다. 개정(안)의 도출을 위해 이 연구에서는 문헌조사, 국내 도서관 및 VIAF의 전거레코드 분석, 도서관 실무진과의 집단면접 등의 방법을 활용하였다.

Objectives: The purpose of this study was to examine search trends and their meanings for major uninsuired Korean medicine (KM) treatments through analysis of an online portal search results. Methods: Keywords searches were performed using Naver Datalab on 4 July 2023. From January 2016 to June 2023, monthly relative search volume (RSV) for keywords 'pharmacopuncture', 'Chuna', and 'needle-embedding therapy', and 'herbal decoction' were extracted with a score between 0 and 100. For the obtained RSVs, longitudinal changes over time, characteristics according to sex and age group, and correlations between them were investigated. Results: The ranking of RSV for each keyword has changed from 'Chuna', 'herbal decoction', 'needle-embedding therapy', and 'pharmacopuncture' to 'Chuna', 'herbal decoction', 'pharmacopuncture', and 'needle-embedding therapy' after 2019. Overall, the RSV of needle-embedding therapy continuously decreased, while that of pharmacopuncture continuously increased. In 2019, a rapid increase in the RSV of Chuna was observed, and in 2020, a rapid increase in the RSV of herbal decoction was observed. There was a difference in the longitudinal change pattern of RSV for the keywords by age group. Importantly, in the elderly, changes in RSV were observed in a favorable pattern to KM treatment. Conclusion: Our findings enable estimation of the public's interest and its changes for the four uninsuired KM treatment, and can be used as basic data to strengthen health insurance coverage in Korea. Specifically, changes in interest in KM treatments according to sex and age can be referred to.

Objectives: Several domestic search systems for research projects providing capabilities of searching and managing the research information based on metadata have been completed, although they cannot search projects for specific domains such as the Oriental Medicine field. Therefore, in this paper we propose an effective method for collecting and refining information of research projects in the oriental medicine field. We also design and implement a search management system based on the collected information. Methods: We chose three search elements and defined the collecting process for research projects. The collected information was refined to enhance the quality of results. Then, the search management system was implemented by Adobe Flex. Results: We were able to collect 1,688 research projects in the oriental medicine field. We also implemented the search management system, which provides the functionalities of search and management such as input, update, delete, spreadsheet import/export of R&D projects, user management and access control. Conclusions: The collected information and the search management system will be used in a project analysis system which will be constructed in the future. The project analysis system could help to analyze trends in oriental medicine research as well as construct a technical roadmap.

하루에도 수백만 건 이상의 방대한 질의어가 입력되는 검색엔진을 통해 인터넷 검색 패턴을 분석하는데 활용될 수 있는 질의어 분포의 정상성을, Pareto 분포와 Zipf 모형을 이용해 검토하였다. 실제2주일간의 일간 검색어 분포를 Pareto 모형으로 적합 시킨 결과, 그 기울기가 1.33에서 1.34 정도로 일관되게 측정되고 있어 Pareto 분포를 이용해 일간질의어 분포의 정상성을 평가할수 있음을 제시하였다. 이런 연구결과는 사회적 관심사와 그 변동 흐름을 해석하는데 보다 객관적이며, 효율적인 자료를 제공해 줄 수 있을 것이다.

The admission officer system that is discussed by research topic was introduced just six years ago. So, domestic journals for research trends analysis of admission officer system are not enough. From the time of the end of 1st government financial support project (2007~2012) for admission officer system, it is important things that to summarize the results of study and to look at the implications. The contents of this study will help that other researchers search the study directions. The implication of the research are as follows. First, we can see that range of research is widening and research is advancing. Second, the journals that related to high school will be come out more frequently. Finally, after accumulation of data, in-depth study analysis will be also come out.

In this paper, we examined trends and regulations of the global medical equipment industry through literature search. The medical equipment industry is attracting attention as a new growth engine in the Fourth Industrial revolution. However, the medical device industry is a highly competitive field due to product diversity, short product life cycle and technological advances. In addition, Medical equipment are related to human health and safety. Therefore, it can only be exported if it is approved by national or international standards. Therefore, from the development stage of the product, the medical equipment should designate the country to be exported and develop a medical equipment that meets the requirements for licensing the medical equipment in the country. Therefore, In this paper, In this paper, we will present the practical considerations of the medical equipment exporting company by examining the global medical equipment market trends and the regulations related to medical equipment in major countries.

This paper addresses the antitrust case of Google's general search service to find evidence and logic used for defining markets, and the proof of dominant power and its abuse in detail. This antitrust case has certain meaning because it is not easy to apply traditional approaches to a general search service, which has two-sided market characteristics. This paper finds some implications through an analysis of the antitrust case shown below. First, for market definition, the overall qualitative analysis can be used to draw conclusions without a quantitative analysis, such as a Small but Significant and Non-transitory Increasing in Price (SSNIP) analysis. Second, the multi-homing behavior seems to be one of the key factors in judging the dominant power in Internet-based services. Lastly, the fact that the value of traffic can differ based on the traffic source needs to be considered to address the competition issue of Internet-based services.
