With the development of semantic web technologies in information retrieval area, the necessity for thesaurus is recently increasing along with internet lexicons. A thesaurus is the combination of classification and a lexicon, and is the topic map of knowledge structure expressing relations among concepts(terms) subject to human knowledge activities such as learning and research using formally organized and controlled index terms for clarifying the context of superordinate and subordinate concepts. However, although thesaurus are regarded as essential tools for controlling and standardizing terms and searching and processing information efficiently, we do not have a Korean thesaurus for geology. To build a thesaurus, we need standardized and well-defined guidelines. The standardized guidelines enable efficient information management and help information users use correct information easily and conveniently. The present study purposed to build a thesaurus system with terms used in geology. For this, First, we surveyed related works for standardizing geological terms in Korea and other countries. Second, we defined geological topics in 15 areas and prepared a classification system(draft) for each topic. Third, based on the geological thesaurus classification system, we created the specification of geological thesaurus. Lastly, we designed and implemented an internet-based geological thesaurus system using the specification.

본 연구에서는 정신분열증 환자들이 정서상태를 개념화하고 얼굴표정을 통하여 타인의 정서 상태를 판단하는 과정을 정상인과 비교하였다. 연구1에서는 만 19세-46세의 정신분열병 환자 19명에게 정서 관련 형용사 15개로 구성된 105개의 형용사 쌍에 대하여 유사성을 평정하도록 하여 MDS로 분석한 결과, 쾌/불쾌와 각성의 두 차원이 일관되게 보고되고 있는 정상집단과는 달리 정신분열병 집단의 자료에서는 쾌/불쾌 차원만이 뚜렷하게 나타나고 각성 차원은 얻어지지 않았다. 연구 2에서는 다양한 정서를 표현한 얼굴 사진 28개를 정신분열병 환자 30명과 대학생 31명에게 제시하고 각 사진의 인물이 경험하고 있는 내적 상태를 쾌/불쾌와 각성의 두 차원에 대하여 각각 7점 척도로 평정하도록 한 결과 정신분열병 집단은 대학생 집단에 비하여 쾌/불쾌 차원에서는 보다 긍정적으로 평정하는 경향이, 각성 차원에서는 상대적으로 낮게 평가하는 경향을 나타냈다. 특히 부정적이고 각성 수준이 높은 내적 상태를 표현하는 사진 자극에 대하여 정신분열병 환자 집단이 각성수준을 과소평가하는 경향이 두드러지게 나타났다. 이와 같은 결과를 종합하여 볼 때, 정신분열병 환자들은 정서상태의 개념화 과정에서 각성 차원에 대하여 상대적으로 낮은 민감도를 보이고 있으며, 특히 부정적인 정서상태를 표현하는 얼굴들에 대란 판단에서는 각성 차원을 과소평가하여 높은 각성수준을 나타내는 표정과 낮은 각성수준을 변별하는데 어려움을 보이는 것으로 해석될 수 있다. 본 연구의 결과는 정신분열병 환자들은 자율신경계의 높은 각성 수준으로 인하여 각성 수준을 더 높일 가능성이 있는 자극을 회피하는 경향이 있다는 Mednick의 가설과 일관되는 결과로 이들의 각성 수준에 대한 낮은 민감도는 방어적인 회피성향의 지속에 따른 둔감화의 결과로 해석될 수 있다. 효과는 GSR를 비롯한 자율신경계지표에서 잘 반영되었다.^2$=.792가 되었다. 설명되는 누적분산값은 67.18%였다.주관적 평가의 결과와 객관적 평가 결과를 이용해 마직물의 태를 평가하는 산출식을 제시하였다. 태 평가치의 경우 16가지 특성치를 모두 넣는 방법과 stepwise 방법, 또 Kawabatark 사용한 순차적 군 회귀법의 세가지 방법의 회귀식 중 16가지 특성치를 모두 넣는 방법의 결정계수가 가장 높았다.tosterone농도는 107.7$\pm$12.0 pmol／l이었고, 남성의 타액내 농도는 274.2$\pm$22.1 pmol／l이었다. 이상의 결과로 보아 본 연구에서 정립된 EIA 방법은 RIA를 대신하여 소규모의 실험실에서도 활용할 수 있을 것으로 사려된다.또한 상실기 이후 배아에서 합성되며, 발생시기에 따라 그 영향이 다르고 팽창과 부화에 관여하는 것으로 사료된다. 더욱이, 조선의 ${\ulcorner}$구성교육${\lrcorner}$이 조선총독부의 관리하에서 실행되었다는 것을, 당시의 사범학교를 중심으로 한 교육조직을 기술한 문헌에 의해 규명시켰다.nd of letter design which represents -natural objects and was popular at the time of Yukjo Dynasty, and there are some documents of that period left both in Japan and Korea.

By reviewing domestic and international papers, this study examines various fields in which drones are used, and based on the results, fields are suggested in which drones can be used for the work of firefighters. Overall, the research results show that drones are most commonly used for search (51%), disaster and fire monitoring (35%), and delivery (14%). Specifically, in the search field, using a drone is more efficient in terms of manpower, equipment, time, and cost than using people, which is the current practice. Secondly, in disaster and fire monitoring, drones can analyze and identify disasters and fire sites in real time. Therefore, it was confirmed that the use of drones is helpful in securing the safety of firefighters and identifying a disaster site. Third, research in logistics shows that drones can secure the so-called golden time in emergency situations by delivering rescue and relief supplies, emergency medicine, and blood in short order. In a rapidly changing disaster environment, and considering aging in firefighters, this study is meaningful in that it promotes drone utilization in the firefighting field by investigating basic data on drone utilization plans.

Microbial characteristics of bacterial population were investigated in human remains and soil inside the bones in excavated grave no.4 and no.5 at Keundokgol site, Osu-ri, Buyeo. Phylogenetic characteristics of bacterial populations were analyzed by direct extracting of ancient DNA. In this study, based on the 16S rDNA sequences, in case of grave no.4, 319s from human remain were classified into 11 phyla, and 462s from soil were classified into 16 phyla. In case of grave no.5, 271s from human remain were classified into 10 phyla, and 497s from soil were classified into 11 phyla. Especially, Actinobacteria phylogenetic group are dominant group of bacterial populations in grave no.4 and no.5. Also, most of these were analyzed uncultured group. Thus, the discovery of a diversely microbial community and uncultured group was thought to be due to the specificity of the sample. Conclusively the general excavated human bones were contaminated with soil bacteria species their near around. This results contribute to preservation and management of ancient human bone from archaeological sites.

Energy management systems (EnMS) contribute to sustainable energy saving and greenhouse gas reduction by emphasizing the role of energy management in production-oriented economies. Although understanding the methods used to measure energy performance is a key factor in constructing successful EnMS, few attempts have been made to examine these methods, their applicability, and their utility in practice. To fill this research gap, this study aimed to deepen the understanding of energy performance measures by focusing on four energy performance indicators (EnPIs) proposed by ISO 50006, namely the measured energy value, ratio between measured values, linear regression model, and nonlinear regression model. This paper presents policy and managerial implications to facilitate the effective use of these measures. An analytic hierarchy process (AHP) analysis was conducted with 41 experts to analyze the preference for EnPIs and their key selection criteria by the industry sector, and organization and user type. The findings suggest that the most preferred EnPI is the ratio between the measured values followed by the measured energy value. The ease of use was considered to be most important while choosing EnPIs.

Due to the recent and rapid globalization, logistics outsourcing has expanded globally and is seen as a means of creating a robust logistics system. However, many businesses continue to have difficulties with their logistics outsourcing contracts, which compels them to reinstate the logistics function for internal management. This study aims to investigate how organizational capabilities of logistics service providers (LSPs), notably flexibility, integration, innovation, and technological capabilities, impact on the logistics outsourcing success in Ugandan food processing firms. Using a structured questionnaire survey, cross-sectional data collected from 211 food processing firms in Kampala - Uganda were analyzed by partial least squares-structural equation modeling (PLS-SEM) using SmartPLS 3.3.7 software to examine the theorized relationships. The study findings revealed that whereas the technological and innovation capabilities positively and significantly influence logistics outsourcing success, the effects of flexibility and integration capabilities were insignificant. Additionally, the importance-performance map analysis (IPMA) reveals that the technological capability is a priority capability, followed by the innovation capability if logistics outsourcing success is to be achieved. Conversely, flexibility and integration capabilities are of low priority.
