정보검색 시스템이나 웹(Web)이 방대해지고 초보적 수준의 사용자들이 늘어남에따라 간단한 조작만으로 원하는 정보를 얻어 낼 수 있는 도구의 개발이 점점 중요해지고 있다. 일반적으로 정보검색 시스템 (검색엔진 포함)의 검색되는 결과의 수는 정보검색 시스템 별로 다양하고 많은 시스템들이 검색을 못하거나 방대한 결과를 제시한다. 본 논문은 방대한 결과를 여러가지 다양한 view로 볼 수 있고 사용자의 피드백에 의해 정보를 재 검색함으로서 검색하고자 하는 문서를 보다 정확하게 검색할 수 있도록 도와주는 결과 렌즈 (Results Lens: RL)를 제안한다. 본 논문에서 제시한 결과 렌즈는 다양한 view로의 결과를 수정(refine) 할 수 있으며 웹을 기반으로하는 플러그인(plug-in)으로 제공함으로써 유용성 및 확장성이 크다.

Purpose: Poor nutrition in hospitalized patients is closely linked to an increased risk of infection, which can result in complications affecting mortality, as well as increased length of hospital stay and hospital costs. Therefore, adequate nutritional support is essential to manage the nutritional risk status of patients. Nutritional support needs to be preceded by nutrition screening, in which accuracy is crucial, particularly for the initial screening. To perform initial nutrition screening of hospitalized patients, we used the Catholic Kwandong University (CKU) Nutritional Risk Screening (CKUNRS) tool, originally developed at CKU Hospital. To validate CKUNRS against the Patient-Generated Subjective Global Assessment (PG-SGA) tool, which is considered the gold standard for nutritional risk screening, results from both tools were compared. Methods: Nutritional status was evaluated in 686 adult patients admitted to CKU Hospital from May 1 to July 31, 2018 using both CKUNRS and PG-SGA. Collected data were analyzed, and the results compared, to validate CKUNRS as a nutrition screening tool. Results: The comparison of CKUNRS and PG-SGA revealed that the prevalence of nutritional risk on admission was 15.6% (n = 107) with CKUNRS and 44.6% (n = 306) with PG-SGA. The sensitivity and specificity of CKUNRS to evaluate nutritional risk status were 98.7% (96.8 ~ 99.5) and 33.3% (28.1 ~ 39.0), respectively. Thus, the sensitivity was higher, but the specificity lower compared with PG-SGA. Cohen's kappa coefficient was 0.34, indicating valid agreement between the two tools. Conclusion: This study found concordance between CKUNRS and PG-SGA. However, the prevalence of nutritional risk in hospitalized patients was higher when determined by CKUNRS, compared with that by PG-SGA. Accordingly, CKUNRS needs further modification and improvement in terms of screening criteria to promote more effective nutritional support for patients who have been admitted for inpatient care.

Malnutrition has been associated with higher hospital costs, mortality, rates of complications and longer length of hospital stay. Several nutritional screening tools have been developed to identify patients with malnutrition risk. However, many of those require much time and labor to administer and may not be applicable to a Korean population. Therefore, the aim of this study was to develop nutritional screening tool for Korean inpatients. Then we compare nutritional screening tools that developed and previously described. Seven hundred sixty-four patients at hospital admission were screened nutritional status and classified as well nourished, malnutrition stage 1 or stage 2 by the KNNRS (Kyunghee Neo Nutrition Risk Screening), PG-SGA (Patient-Generated Subjective Global Assessment) and NRS-2002 (Nutritional Risk Screening-2002). The KNNRS, PG-SGA and NRS-2002 respectively classified 28.7%, 51.3%, 48.5% of patients as malnourished status. Compared to the PG-SGA, the KNNRS had sensitivity 60.7% (95% CI 54.2-67.0) and specificity 81.2% (95% CI 75.3-85.2). Agreement was fair between KNNRS and PG-SGA (k = 0.34). Compared to the NRS-2002, the KNNRS had sensitivity 57.8% (95% CI 53.4-60.9) and specificity 64.4% (95% CI 60.2-69.8). Agreement was poor between KNNRS and NRS-2002 (k = 0.18). These result should include that the KNNRS and PGSGA have clinical relevance and fair concordance. However the rate of malnourished patients by KNNRS were less than by PG-SGA. For more effectivity of nutritional screening and management, the criteria of KNNRS would be better revised.

시소러스는 정보검색과정에서 용어를 통제하여 색인과 검색에서 중요한 기능을 수행하는 도구로 사용되고 있는 통제용어집이다. 그러나 정보검색시스템 환경의 변화에도 불구하고 기존의 시소러스와 시소러스의 작성지침으로 사용되고 있는 국제 표준인 ISO 2788이나 Z39.19에서 제시하고 있는 기준은 용어간의 관계를 단순히 표현하고 있어 색인이나 검색시 용어통제의 어려움을 겪고 있다. 본 연구는 시소러스의 용어관계를 국제 표준과 현재 사용되고 있는 각종 시소러스를 비교 분석하여, 시소러스 용어관계의 확장방안을 제시한다.

Objective: The purpose of this study is to analyze comprehensive lifestyle assessment and other assessments which evaluate essential lifestyle factors, including physical activity, nutrition and activity participation. Methods: To analyze the comprehensive lifestyle assessment, from January 2001 to June 2019, a literature search was conducted using the CINANL, NDSL, PubMed, and RISS databases. The search terms were 'lifestyle assessment' OR 'lifestyle profile' OR 'lifestyle test'. In terms of other assessments of essential factors of lifestyle, from January 2010 to June 2019, articles were searched using similar databases. The search terms were 'physical activity assessment' OR 'physical activity participation profile', 'nutrition assessment', 'activity participation assessment' OR 'activity participation and lifestyle'. Results: A total of 4,165 articles were obtained, and finally 31 articles were selected according to the inclusion criteria. Among 31 articles, there were five with comprehensive lifestyle assessments, and all of them were self-report questionnaires. The most popular assessments were the Health Enhancement Lifestyle Profile (HELP) and the Health-Promoting Lifestyle Profile (HPLP), which were used in three articles (33%). In terms of assessment of physical activity, the most frequently used evaluation method was the self-report questionnaire, which was used in seven articles (58%) followed by objective assessments, which were used in four articles (33%). It was demonstrated that the Mini-Nutritional Assessment (MNA) was the most frequently used for nutrition assessment in the elderly. There were five types of assessment tool used for activity participation. Among them, meaningful activity participation assessment (MAPA) was the most frequently used tool. Conclusion: As a result of the systematic review, it was found that there are 21 assessments related to the evaluation of lifestyle in the elderly. Most assessments employed the self-report questionnaire method and mainly evaluated frequency and duration of participation in drinking, smoking, exercise, nutrition and social activities. Assessments of essential lifestyle factors were the self-report questionnaire method and the participation and frequency of activity. Therefore, by analyzing assessment tools, types of items and measurement methods of comprehensive lifestyle assessments and other assessment of essential lifestyle factors, this study provides the basic data on which to develop a standardized assessment tool that can evaluate the multifaceted lifestyle profile of the elderly.

The importance of WWW search services is increasing as Internet information resources explode. An evaluation of current 9 search services was first conducted by comparing descriptively the features concerning indexing, searching, and ranking of search results. Secondly, a couple of search queries were used to evaluate search performance of those services by the measures of retrieval effectiveness. the degree of overlap in searching sites, and the degree of similarity between services. In this experiment, Alta Vista, HotBot and Open Text Index showed better results for the retrieval effectiveness. The level of similarity among the 9 search services was extremely low.

현재 네트워크 보안 취약점을 자동으로 검색해주는 다양한 도구들이 인터넷에 공개되어 있어 이러한 도구들을 이용한 취약점 정보수집 및 네트워크 검색공격으로 비롯된 해킹사고가 크게 증가하고 있다. 이와 같은 검색 공격에 대한 탐지 시스템은 "False-Positive(실제 공격이 아닌데 공격이라고 탐지)"와 "False-Negative(실제 공격인데 공격이 아니라고 탐지)"를 줄이는 것이 중요하다. 그러나 현재 공개되어 있는 실시간 스캔 탐지 시스템은 오탐율이 높을 분만 아니라 다양한 스캔 기법에 대해서 탐지를 할 수 없는 것이 사실이다. 본 논문에서는 다양한 포트스캐닝 기법기반의 공격에 대해서 탐지 가능하고 오탐율을 최소화한 실시간 스캔 탐지 시스템을 구현한다.실시간 스캔 탐지 시스템을 구현한다.

최근 반복적 설계에 대한 해결방안으로 제시되고 있는 디자인패턴을 체계적으로 분류, 공유하여 사용하려는 연구가 진행되고 있으나, 시스템 설계자 개개인이 제시한 패턴은 공유 대상에서 제외되고 있다. 또한, 특정 CASE 도구를 사용하여 모델링한 구조는 컴포넌트화되더라도 특정 도구나 플랫폼에 독립적으로 사용될 수 없었다. 본 논문에서는 기존 디자인패턴뿐만 아니라 사용자들에 의해 새로이 제시된 패턴을 모델링하는 패턴 에디터를 이용하여 설계정보를 도구와 플랫폼에 독립적인 XML코드로 컴포넌트화 할 수 있는 XML 기반의 디자인패턴 관리시스템을 설계, 구현하였으며, 효과적인 패턴 검색을 위해 Spreading Activation 검색 방법을 사용하였다.
