  • 시소러스 작성에 있어서 가장 현실적인 어려움은 용어의 수집에 있다. 용어사전 뿐만 아니라 어휘사전도 시소러스의 중요한 용어 수집원으로 사용될 수 있다. "표준국어대사전"은 어문 규정을 충실히 반영한 우리나라의 대표사전이다. 또한 "표준국어대사전"은 단순히 표제어에 대한 용어 정의뿐만 아니라 해당 용어에 대한 다양한 정보를 체계적으로 담고 있기 때문에, 이를 시소러스 사전 구축에 활용할 수 있을 것이다. 본 연구는 "표준국어대사전"이 갖고 있는 다양한 용어관계 정보를 시소러스 용어관계로 정의하는 방안을 모색하였다. 또한 용어의 분리, 동등관계와 계층관계의 설정, 한정어의 사용, 북한어 관계 등 시소러스 구축에서의 문제점과 해결 방안을 제시한다.

  • Purpose: This study utilized data from the Korean National Health and Nutrition Examination Survey (KNHANES) to explore differences in the timing of menarche in Korean girls according to blood heavy metal concentrations. Methods: This study performed a secondary analysis of cross-sectional data from the sixth KNHANES. Data from 179 female children and adolescents aged 10~18 were included in this study. The relationships of blood heavy metal concentrations (lead, mercury, and cadmium) with age of menarche were analyzed using complex sample multiple logistic regression. Results: In the participants of this study, the geometric mean values of blood lead, mercury, and cadmium concentrations were 1.15±0.04 ㎍/dL, 1.80±0.08 ㎍/L, and 0.30±0.03 ㎍/L, respectively. Mercury poisoning (>5 ㎍/L) was found in 1.5% of participants. Furthermore, significant relationships were found between blood lead and mercury concentrations and age at menarche (p for trend: p<.001 and p=.015, respectively). Conclusion: Through an analysis of national big data, this study found evidence that Korean girls showed a younger age at menarche in response to higher blood lead and mercury concentrations. To prevent and manage precocious puberty in Korean children and adolescents, a systematic policy that monitors both exposure to environmental hazards and blood heavy metal concentrations is needed.

  • To choose one or more appropriate molecular markers or gene regions for resolving a particular systematic question among the organisms at a certain categorical level is still a very difficult process. The primary goal of this review, therefore, is to provide a theoretical information in choosing one or more molecular markers or gene regions by illustrating general properties and phylogenetic utilities of nuclear ribosomal DNA (rDNA) and mitochondrial DNA (mtDNA) that have been most commonly used for phylogenetic researches. The highly conserved molecular markers and/or gene regions are useful for investigating phylogenetic relationships at higher categorical levels (deep branches of evolutionary history). On the other hand, the hypervariable molecular markers and/or gene regions are useful for elucidating phylogenetic relationships at lower categorical levels (recently diverged branches). In summary, different selective forces have led to the evolution of various molecular markers or gene regions with varying degrees of sequence conservation. Thus, appropriate molecular markers or gene regions should be chosen with even greater caution to deduce true phylogenetic relationships over a broad taxonomic spectrum.

  • Purpose: This study was conducted to evaluate the relationships among the service education satisfaction, service involvement, and customer orientation of hospital employees after yearly-planned MOT service education. Methods: The data collection was done through the questionnaire survey in a university hospital located in D city from March 15 to 31, 2010. The statistical analysis was done by SPSS/WIN 18.0 program. Results: The enrolled employees were two hundred and seventy six. Among the characteristics of employees, adequate work load, good payment, reasonable promotion system, suitability of work aptitude and good relationships with staff improved the service education satisfaction, customer orientation, and service involvement of hospital employees. For the customer orientation, old age and lower educational background were positive factors. The correlations among the service education satisfaction, customer orientation, and service involvement of hospital employees were significant. The factors that affect customer orientation and service involvement were found to be age, suitability of work aptitude and service education satisfaction. Conclusion: In conclusion, customer orientation and service involvement were related with the satisfaction of employees for working condition and service education. In terms of good medical service quality, plans for maintaining adequate working environment and systematic service education should be established.

  • Websites in the Internet are uncontrollable domain and various contents in websites lead people's activities and thoughts and new business paradigms for the future. These phenomena are from expanding the social network based on the endless growth of information technology. Websites are composed with many of links and communicating and expanding their virtual area by links, inbound, outbound, onsite, and of offsite links. Research and practice in digital information on the web have focused on finding and measuring artifacts, factors and attributes of web structure and contents from the perspective that information is a resource and property of products and services. Websites links is one of the core artifacts for understanding the virtual area. This study identifies the role of web link structure and webpage keyword as artifacts and examines their relationships by webpage rank by a minimal hub as performance in the business websites that are serving tourism information. Discovering relationships of links provides managerial insights on organizations virtual activities and systematic understandings about digitalized organizational information in the information use environment.

  • Giemsa C-banded karyotypes of A. thunbergii, A. deltoide-fistulosum, A. cyaneum and A. cyaneum var. deltoides were analyzed, and the interspecific relationships were investigated on the basis of the C-banding patterns. The banding pattern of each species was unique and made possible an easy and clear separation among them. A. thunbergii and A. deltoide-fistulosum revealed very close banding relationship but a. cyaneum and A. cyaneum var. deltoides showed significant difference in banding pattern in spite of their close plant systematic position.

  • We have recognized that an organization should be viewed from a multifaceted perspective necessitating a sophisticated analytical and systematic approach to monitor and improve organizational performance. Although some performance measurement systems have been proposed and are currently being used in many organizations, no performance measurement system has presented a mechanism for integrating all of the information of performance measures in a way that considers relationships between them. This paper introduces the implementation of the performance information integration method(PIIM) which synthesizes all useful information of performance measures with consideration of the relationship and generates a single, global, organizational performance score. The PIIM was empirically validated by implementing in one of missouri Veterans Homes.

  • The genus Gonia (Diptera: Tachinidae) is revised for the Korean species. We recognize four previously known species (G. chinensis, G. divisa, G. foersteri, and G. klapperichi), three newly recorded species in Korea (G. distinguenda, G. olgae, and G. ussuriensis) and a species new to science (G. nigricoma Lee and Han, sp. nov.). We here provide a key, descriptions, photographs and illustrations. We also inferred the phylogenetic relationships of the representative Palaearctic species using cladistic method.

  • 한국산 초파리아속에 속하는 quinaria section 7종 (D. angularis, D. brachynephros, D. curvispina, D. kuntzei, D. nigromacula ta, D. takadai, D. unispina)과 virilis section 3종(D. virilis, D. tsigana, D. lacertosa)을 대상으로 형태적 수리분석을 실시하여 종간 계통학적 유연관계를 알아보았다. 집괴분석과 분지분석을 실시한 결과 초파리아속 10종은 D. virilis, D. tsigana, D. lacertosa의 제1군과 D. angularis, D. brachynephros, D. curvispina, D. kuntzei, D. nigromaculata, D. takadai, D. unispina 제2군으로 나눌 수 있다. 집괴분석 결과 제2군은 3개의 아군 즉, D. angularis와 n. brachynephros가 집괴된 후에 D. unispina가 집괴되는 아군과, D. curvispina와 D. takadai가 집괴된 후에 D. kuntzei가 집괴되는 아군, 그리고 D. nigromaculata 아군으로 나눌 수 있다. 그리고 D. virilis와 D. lacertosa가 가장 먼저 분지된 종이었으며, D. tsigana가 그 다음이었다. D. virilis가 속한 제1군은 제2군보다 더 먼저 파생되었다고 할 수 있으나, 제1군이 제2군의 직접적인 조상형은 아니고 다른 조상형이 있었을 것이며, 제2군에서는 D. nigromaculata가 가장 먼저 파생되었고, D. kuntzei가 가장 늦게 파생되었다고 생각된다.

  • 사물인터넷(IoT)은 다양한 디바이스가 유무선 네트워크를 통해 연결되어 정보를 수집, 처리, 교환, 공유하는 환경이다. 대표적 디바이스가 스마트폰 같은 모바일 IoT 디바이스인데, 사용자에게 고성능서비스를 제공하기 위해 파워를 많이 소비하지만 상시 공급할 수 없어서 주어진 IoT 환경에 적합하게 파워 관리를 하는 것이 필수적이다. 하지만 기존 모바일 IoT 디바이스의 파워 관리에는 AP, AP 내/외부 HW 모듈, OS, 플랫폼, 어플리케이션 등 다양한 요소가 복잡하게 얽혀 있어서 이 관계를 쉽게 파악하고 관리하는 체계적인 방법이 필요하다. 또한 파워 관리와 연관된 다양한 관리 정책, 운영 환경, 알고리즘 등 가변 요소를 분석하고 이를 파워 관리 개발에 반영하는 것이 필요하다. 본 논문에서는 이러한 문제점을 해결하고 모바일 IoT 디바이스 파워 관리를 체계적으로 개발하기 위한 공학 원칙과 이를 기반으로 한 방법을 제안한다. 실행가능성 검증을 위해 커넥티드 헬멧 시스템 파워 관리가 사례연구로 사용되었다.
