평가작업은 기록관리 업무에서 가장 중요한 기능 중에 하나이다. 즉, 기록관리에 있어서 평가란 기록물의 가치를 평가하는 것으로, 그 결과 지속적으로 유지 보존되어야 하는 업무적 가치를 지니거나 지속적 활용성을 지닌 기록을 체계적으로 선정하고, 그 보유기간을 결정할 수 있다. 현재 엄청난 양의 기록물이 생산되는 환경에서 선별의 범위와 방식을 규정하여 효용의 극대화를 추구하게 하는 기록물평가의 중요성은 더욱 부각된다고 볼 수 있다. 본 연구는 각국(영국, 미국, 캐나다, 호주)의 국립기록원이 제정한 영구적 기록물선정과 폐기를 위하여 수립된 평가정책을 1) 평가정책의 목표, 2) 평가목적, 3) 평가기준, 4) 평가절차, 5) 특별 고려사항 등 다섯 가지 항목에 대해서 분석하여 비교하였다. 또한, 본 연구는 법령으로 국가기록물을 체계적으로 선별 수집하기에는 역부족이라 생각하여 국가기록원이 국가기록물을 평가ㆍ선별하는 데 도움을 줄 수 있는 평가정책을 개발하는 것이 바람직하다고 보고, 평가정책 수립 시 고려사항을 제시하였다.

BIM 기술의 하나인 COBie 포맷의 출현으로 설계와 시공단계에서 발생한 정보가 운영단계로 자동 전송이 가능해지면서 BIM을 중심으로 하는 유지관리시스템 개발 프로세스가 건축물을 중심으로 실험되고 있다. 하지만 BIM 시장 확대가 예상되는 현재 시점에서 건축물을 포함한 토목시설과 산업시설에서의 COBie 활용성에 대한 검토가 선행되어야 할 필요가 있다. 본 연구는 "공공하수도시설 운영 관리 업무지침"과 현재 운영중인 하수처리시설을 대상으로 진행하였고 후자는 업무지침의 결과를 검증하고 보충하는데 의의가 있다. 본 연구에서 도출된 결론은 세 가지로 요약된다. (1) 자산 모델링 방법인 COBie는 시운전 정보를 포함하기에는 충분하지 않으며, (2) 하수처리시설 모델링에 필요한 IFC 개발과 패밀리 구축이 반드시 필요하다. 그리고 (3) 현재의 운영관리시스템에 적합하게 설계된 COBie 모델은 산업시설분야의 COBie 포맷 타당성을 높여 줄 것이다. 본 연구 결과는 산업시설에서의 COBie 적용을 위한 기초 자료로 이용될 것으로 기대된다.

인용분석은 학자들의 연구실적 평가에 가장 많이 사용되는 방법 중 하나이지만 비평가들은 오늘날의 인용분석 자료와 방법론에 근본적인 문제가 있다고 주장한다. 전통적 인용분석 방식은 인용품질과 인용소음뿐만 아니라 언어, 시간, 문화와 같은 비수치적인 요소들을 고려하지 않아 단순하고 그릇된 평가를 가져올 수 있으며, 적용 범위가 각각 다르고 불완전한 인용 데이터베이스들은 충돌적인 인용분석결과를 초래하기 쉬울 수 있다. 이러한 문제들을 해결하려면 포괄적인 인용데이터를 다 방면과 다 방식으로 분석하는 새로운 인용분석연구가 필요하다. 본 논문은 Web of Science, Scopus와 Google Scholar를 비교 분석한 연구의 결과를 논의하며 기존의 인용분석 방법의 약점을 극복하기 위해 설계한 CiteSearch라는 프로토타입 시스템을 간략하게 설명한다.

국가종합목록은 한 국가내 모든 도서관의 서지 및 소재정보를 제공하여 도서관간 자료의 공동활용을 가능하게 하는 정보하부구조로 최근 여러 나라에서는 정보검색 표준인 Z39.50 프로토콜을 응용한 국가종합목록 프로젝트가 진행되고 있다. 국내의 경우 공공, 대학, 전문도서관 등 관종별 종합목록데이터베이스 구축이 각기 진행되고 있으며 이러한 국내 현실여건에서는 이미 개별적으로 구축된 종합목록 데이터베이스들을 통합하는 방식보다는 Z39.50 프로토콜을 이용한 분산 검색으로 논리적 가상 국가종합목록을 구축하는 것이 바람직하다. 따라서, 물리적 통합 형태인 중앙화 방식과 Z39.50 프로토콜을 통한 분산화 방식이 혼합된 하이브리드 방식을 국가종합목록 구축 방안으로 제안하고 구체적으로 국가종합목록 구축의 노드가 되는 국가서지기관과 종합목록 운영기관의 역할과 협력방안을 제안한다.

Background and Purpose : Allergic rhinitis is a well-known, relatively controllable chronic disease. Although a number of methods for treating allergic rhinitis have been tried, many patients have not been satisfied with their treatment. Therefore, this study tried to evaluate the effect of a cooperative system of Oriental and Western medicine and to develop a new diagnosis protocol for treatment of allergic rhinitis. Methods : We measured improvement rate and acoustic rhinometry after the allergeninduction test and performed a filter paper test as a nonspecific hypersensitivity test with 60 patients who are allergic to house dust mite. Patients were divided into two groups, one treated with Western medicine only and one treated with both Western and Oriental herbal medicine. For the group with Western medicine only, antihistamine for one week and local steroid medicine for two weeks were prescribed. For the group with combined medicine, Oriental herbal medicine was prescribed according to the patient s constitution, along with Western medicine. After all treatments, the above tests were re-performed and the improvement rate was compared. Results and Conclusion : We observed better results in the group treated with both Western and Oriental herbal medicines, comparing improvement rate and the alteration of total nasal volume through acoustic rhinometry after the allergen induction test. In the filter paper test, there was no significant difference between the two groups. In conclusion, we showed the additive effect of Oriental herbal medicine without any severe side effects compared with treatment with Western medicine only. In this study, we set only two patient groups, but further study is required to create various experimental groups and compare among them. We suggest that it might enhance understanding of the improved effect of Oriental herbal medicine in the therapy of allergic rhinitis.

Under environmental stress, such as strong irradiance or nitrogen deficiency, unicellular green algae of the genus Haematococcus accumulate secondary carotenoids, i.e. astaxanthin, in the cytosol. The induction and regulation of astaxanthin biosynthesis in microalgae has recently received considerable attention owing to the increasing use of secondary carotenoids as a source of pigmentation for fish aquacultures, and as a potential drug in cancer prevention as a free-radical quencher. Accordingly, this study generated expressed sequence tags (ESTs) from a library constructed from astaxanthin-induced Haematococcus pluvialis. Partial sequences were obtained from the 5' ends of 1,858 individual cDNAs, and then grouped into 1,025 non-overlapping sequences, among which 708 sequences were singletons, while the remainder fell into 317 clusters. Approximately $63\%$ of the EST sequences showed similarity to previously described sequences in public databases. H. pluvialis was found to consist of a relatively high percentage of genes involved in genetic information processing ($15\%$) and metabolism ($11\%$), whereas a relatively low percentage of sequences was involved in the signal transduction ($3\%$), structure ($2\%$), and environmental information process ($3\%$). In addition, a relatively large fraction of H. pluvialis sequences was classified as genes involved in photosynthesis ($9\%$) and cellular process ($9\%$). Based on this EST analysis, the full-length cDNA sequence for superoxide dismutase (SOD) of H. pluvialis was cloned, and the expression of this gene was investigated. The abundance of SOD changed substantially in response to different culture conditions, indicating the possible regulation of this gene in H. pluvialis.

Background: While the incidence of non-Hodgkins lymphoma (NHL) has been rising worldwide, the reasons remain undefined. Recent research has focused on effect of red andf processed meat intake as a risk factor, but with inconclusive results. We therefore conducted a meta-analysis of data published to date, to ascertain the overall association between intake and NHL. Materials and Methods: A published literature search was performed through Pubmed, Cochrane Library, Medline, and Science Citation Index Expanded databases for articles published in English. Pooled odds ratios (ORs) and 95% confidence intervals (95%CIs) were calculated using random or fixed effects models. Heterogeneity was assessed using Chi-square and I2 statistics. Dissemination bias was evaluated by funnel plot analysis.We performed a formal meta-analysis using summary measures from these studies. Results: In total, 11 published studies were included in the final analysis. The combined analysis revealed that there was significant association between the red meat and NHL risk (OR=1.10, 95%CI: 1.02 to 1.19, p=0.01). Additionally, there was showed significance association between processed red meat and NHL risk (OR=1.17, 95%CI: 1.06 to 1.29, p=0.001). In subgroup analysis, a statistical significant association was noted between diffuse large B-cell lymphoma (DLBCL) (OR=1.20, 95%CI: 1.04 to 2.37, P=0.01) and red meat intake. Conclusions: In this meta-Analysis, there was evidence for association between consumption of red meat, or processed meat and risk of NHL, particularly with the DLBCL subtype in the red meat case.

There are many studies reporting the average carbon dioxide levels in various indoor spaces. However, there have been a few studies showing how carbon dioxide concentration varied at many measurement points in one indoor space. In this study, the changes of indoor carbon dioxide concentration at classroom, library, and kindergarten were reported to find its carbon dioxide distribution change at various locations and altitudes. The maximum carbon dioxide concentration of the 3 sites were measured as 2,684, 2,295, and 1,526 ppm, respectively. These values exceeded the guideline concentration of 1,000 ppm for public places. The concentration of carbon dioxide was higher at upper area than lower area, and this is probably due to the rise of warm breathing air generated from students. In the upper area, the carbon dioxide concentration was higher at center area than four corners. However, in the lower area, the carbon dioxide concentration was higher at four corners than center area. Therefore, it could be concluded that the center of upper area is the best place for the installation of ventilation or carbon dioxide removal system.

The purposes of this study were to summarize the concept of well-being and well-being apartment, to grasp the present condition of apartments which were introduced with well-being elements, and to find out the consumer preferences on well-being elements for apartment planning. Library and internet surveys were performed to summarize the concept of well-being and well-being apartment and to grasp the present condition of apartments which were introduced with well-being elements. Questionnaire survey was carried out from 2nd to 22nd of June 2005, to investigate the preferences on well-being elements for apartment planning. The respondents were 250 residents who are from thirties to fifties and living in urban area. As results, respondents think that 'living for health of body and mind' about concept of well-being and 'certificated apartments by green building rating system' or 'apartments introduced ecological factor' about concept of well-being apartment. They answered that 'yes' about 'Do you have intention to buy well-being apartment?'. The elements in aspect of complex planning having the preference were revealed that promenade for complex design, ecological garden or walking space for landscape design, outdoor exercise space for outdoor design, and security system for foundation equipment.
