전 세계적으로 정보통신기술의 발전과 융합을 통해 산업 전반에 걸쳐 소프트웨어의 영향력이 점차 증가 되고 있다. 기존의 하드웨어 중심에서 소프트웨어 중심으로 기술이 발전하고 있으며, 소프트웨어 안에서는 상용 소프트웨어의 사용을 탈피하고 공개 소프트웨어(OSS, open source software)의 활용이 늘고 있으며, 정부기관에서도 공개 소프트웨어의 사용 확대를 계획하고 있다. 이에 본 논문에서는 브이월드에서 실제 서비스하고 있는 데이터를 이용하여 WEB 서버 및 WAS(web application server) 서버의 5가지 공개 소프트웨어들의 4가지 조합으로 성능을 비교 분석하여 차세대 브이월드 아키텍처의 효율적인 구성을 위한 공개 소프트웨어의 선택 기준을 설정할 수 있는 지표를 얻고자 하였다. Advance in Information and Communication Technology (ICT) is intensely influenced to increase importance of Software on global ICT industries. The trend of technological development has been transformed from hardware-oriented environment to software-oriented environment. This industrial transformation brought novel trend to Software market. Open Source Software (OSS) has been widely distributed for private uses. At the same time, many governmental offices are planning to expand the use of OSS. In this paper, we analyze the strength and weaknesses of OSSs for both Web and WAS servers based on 4 types of testing environments which are created by the combination of 5 selected OSSs. We anticipated to learn the optimal system architecture design for the next generation of V-World through this research.

Man has an unconscious desire to free oneself from everyday selves and a strong intellectual desire to see and analyze things in a different perspective. This provided a momentum for architectural design that has long been confined to its limits of modernism of being rational and objective. The ever-changing society that we live in filled with various attempts and pluralistic characteristics shows a complex set of attributes that can hardly be defined by a single term. As society moves towards an uncertain and volatile state, the boundary between literature, philosophy and art has dimmed out and converged. Such tendencies have been observable in recent establishments in architecture in the form of introducing external elements and create an alien and farfetched architectural space. Using the "depaysement" defamiliarization method expressing irrationality and randomness, it is applied in various aspects, sharing the counter-rational structure and features of such architectural space. Hence, it is the purposeof this study to delve into the unique characteristics of depaysement through Magritte"s work which reflects the unique pictorial world built under the influence of surrealism, and discover the Depaysement tendencies in modern architectural space. It is apparent in Modern architecture that, owing to the development in digital technology, it is showing process changes in design and an interfacial Depaysement effect in cyberspace, an interlace of reality and the virtual world. In this study, the focus of analysis was architectural properties such as the program, figure/spatial, material and the objective side, but due to mutual text properties, it is bound to be an overlapping analysis.

This study analyzed the composition and contents of acacia(Robinia pseudoacacia) flower extracts, free amino acid of water and methanol extracts and polyphenol compound. Then, the physiological activities of some skin care cosmetic examined. The study results found the followings: The free amino acid of acacia flower hot water extracts was 36.96 mg/g in total, and a total 16 types of free amino acids were isolated. In methanol extract, however, a total of 13.41 mg/g were found in 13 different types. In terms of polyphenol contents, methanol extract was slightly higher than hot-water extract. Regarding the composition of polyphenol compound, 8 different types of phenolic acids and two types of flavonoids were found in hot-water and methanol extracts. The DPPH radical scavenging activity was increased in proportion to the concentration, and the inhibitory activity of tyrosinase in the hot-water and methanol extracts of acacia flower was increased in proportion to the concentration. The ell growth according to human skin cell line, HaCaT was very low cell growth inhibited in an concentration-dependent. The inhibitory activity of elastase and collagenase in the hot-water extract and methanol extracts increased in a concentration-dependent manner. The said results show that because free amino acid and polyphenol contents are rich in the hot-water extract of acacia and methanol extract, they could be very useful as cell growth activating factors or natural antioxidants. To use them as cosmetic ingredients, however, there should be further studies on correlations between the enzyme activity in the cell and various cosmetic components.

장한솔,홍성훈,김민수,장인성,Jang, Han Sol,Hong, Seong Hun,Kim, Min Soo,Jang, In Sung 대한공간정보학회 2015 한국공간정보학회지 Vol.23 No.3

공간정보 오픈플랫폼 서비스인 브이월드가 2012년 시범 서비스를 시작한 후부터 지금까지 많은 국민들의 관심으로 매년 사용자가 폭발적으로 증가하고 있다. 증가하는 사용자의 요구에 따라 앞으로 추가될 서비스 및 사용자의 이용 환경 개선 등의 지표로 활용하기 위해 구체적인 서비스 사용 현황을 알 필요가 있다. 하지만 현재의 시스템에는 실시간 모니터링 시스템이 구축되어 있지 않아 브이월드가 제공하는 2D/3D/Portal 서비스별 하드웨어 자원 사용량과 실사용자들의 이용 패턴 등의 구체적인 서비스 사용 현황을 파악하는데 어려움이 있다. 이에 본 논문에서는 웹 로그를 바탕으로 2D/3D/Portal 서비스별 시스템 사용 현황 및 시스템 로그를 바탕으로 자원(CPU, Memory) 사용 현황 분석을 통해 2015년도 서비스 사용 현황을 분석하고 2014년도 대비 분석 결과를 비교하여, 현 시스템의 문제점 및 해결 방안을 제시한다. Since the V-World, the Spatial Information Open Platform service, has started in 2012, a lot of people have increased explosively every year with their interest. It is necessary to know the specific service status in order to serve as indicators of the improvement of user's environment and the service to be added in the future based on the user's increasing need. However, there is difficulty to figure out more specific service status, such as the usage of hardware resources for 2D / 3D / Portal services and the actual user usage patterns, because the current system does not have the real-time monitoring system. Therefore, in this paper, through the analysis of the usage of system resources for 2D / 3D / Portal services based on web server log and the usage of hardware resources such as CPU, Memory based on system log, we analyze the usage of service in 2015 and compare with the results of the 2014, to present problems of the current system and the solutions about the problems.

2012년 1월부터 공간정보 오픈플랫폼의 서비스가 시작된 이래로, 서비스가 늘어남에 따라 서비스 이용자 수와 시스템의 규모가 크게 증가하게 되었다. 그러나 이러한 오픈플랫폼 시스템이 가지고 있는 하드웨어 자원들이 어느 수준의 서비스를 처리할 수 있는지에 대한 자세한 분석 결과는 전혀 알 수 없었다. 이러한 이유로 특정 이슈와 더불어 서비스 이용자가 급증할 때마다 서비스를 처리하기 위하여 단순히 하드웨어 증설을 통해 일시적으로 서비스 지연 문제를 해결하여 왔다. 이에 본 연구에서는 현재 오픈플랫폼이 보유하고 있는 시스템 성능을 정확히 파악하여 향후 동일한 문제가 발생하지 않도록 근본적인 해결책을 제시하고자 한다. 구체적으로 본 연구에서는 NMON을 이용한 하드웨어 성능 분석과 nGrinder를 이용한 웹서비스 부하 테스트를 통해 오픈플랫폼이 현재 가지고 있는 정확한 시스템 성능을 파악하고, 이후 보다 나은 서비스를 제공할 수 있는 시스템으로 개선하기 위한 자원 재조정 방안을 제시하고자 한다. Since the Spatial Information Open Platform service started in January 2012, the number of service users and the size of the system has increased significantly. However, we could not know the analysis result about how much the hardware resources of the Open Platform system can handle user services. Thereafter, whenever the number of service users are rapidly increased, we simply have solved the service delays using the hardware extension. So, this study presents the obvious solution to avoid the same problem in the future, by pinpointing the system performance of the Open Platform. In this study, through the performance analysis of hardware using NMON and the load test of web service using nGrinder, we intend to get an accurate performance of the Open Platform system. Then we intend to present the resource reallocation method in order to provide better performance of the system.

A 63-year-old female patient was admitted to the hospital with complaints of coldness in the head and right femur, persistent vertigo, dry mouth, vexation, general weakness, anorexia, and hot flashes. After being diagnosed with left-sided ductal carcinoma in 2017 and undergoing partial resection, she was recommended radiotherapy, chemotherapy, and hormone therapy, but she refused and did not receive any treatment. At a checkup in November 2022, the left-sided invasive ductal carcinoma recurred. She underwent partial resection and was scheduled to receive radiotherapy two months later. During hospitalization, the patient received traditional Korean medicine treatment, including Korean herbal medicine (Osuyubujaijung-tang), acupuncture, moxibustion, and cupping. Subjective symptom changes were evaluated daily. At discharge, the patient's symptoms improved, and her condition varied with the presence of Aconitum carmichaelii. This study suggests that "Osuyubujaijung-tang" cared the coldness and vertigo caused by "Han-dam (寒痰)" in patients with Soeumin visceral syncope pattern (少陰人 臟厥症) and that A. carmichaelii played a major role in this outcome.

본 연구는 탄천내 기존 콘크리트 호안블럭을 제거하지 않고 호안녹화용 매트를 적용하여 경관개선 및 생물서식기반을 조성하고자 하는 지역의 복원 효과 확인 및 관리방안을 제안하고자 하였다. 모니터링 결과 식물상은 2006년 18과 38종 3변종 총 41종류, 2007년 19과 56종 3변종 총 59종류, 2008년 29과 59종 8변종 총 64종류로 매년 식물종이 증가하고 있었다. 식물상 분포의 특징은 공법 적용지를 중심으로 식재한 물억새, 수크령 등이 세력을 형성하고 있었으며 범람시 토사 퇴적으로 자생종 중심의 다양한 종이 출현하고 있어 생태적으로 양호한 상태이었다. 현재는 자생종이 우점하고 있었으나 주기적인 범람에 의한 교란 유발 종과 외래종의 증가가 예상되므로 장기모니터링을 통해 관리가 이루어져야 양호한 수변생태계가 형성될 수 있을 것이다. 결국 하천천이 초기식생과 교란지 식생이 혼재되어 나타나는 생육양상이었다. 이와 같은 호안 녹화용 식생매트 공법은 콘크리트를 제거하지 않고 상부에 코이어 매트를 포설하여 불량경관을 개선할 수 있을 뿐만 아니라 식물생육의 기반을 제공하여 계속적인 식물종의 증가에 따른 종다양성을 확보하는데 효과가 있는 것으로 분석되었다. In this study, not only to present the management plan but also to verify the effectiveness for a area of improving the landscape and the area of creating the base of bio-inhabitation in Tancheon stream concrete embankment where were practised the vegetation-mat measures for greening via monitoring i.e. restoration progress. The results of monitoring, there were a total of 41 taxa, 18 families, 38 species, 3 varieties in 2006, moreover in the 2007, there were a total of 59 taxa, 19 families, 56 species, 3 varieties and in the period 2008, 64 taxa, 29 families, 59 species, 8 varieties. Therefore, these site has increased the plant spaces year by year. The distribution of vegetation characteristics shows that Miscanthus sacchariflorus and Pennisetum alopecuroides expands their influence in the area of applying the construction method. Those area appears a diversity of native species by the stream deposition at the flood. Thus, its condition is very soundly ecological health and eco-friend. At present, native species have been dominant, however, disturbed species and invasive species can be expected to increase dramatically in the future. Therefore, it is necessary to a long-range monitoring and management for maintaining an environmentally sound aquatic ecosystem. On this area refer to mix the river vegetation of primary succession and disturbed vegetation. For that reason, the method of constructing the vegetation-mat measures for greening in embankment does not need to remove the concrete and can install a coir-mat on the top. It leads to improve the landscape, moreover, it was analysed the such dramatic changes in the vegetation species richness by providing continuous the plant growth basis have a impact on in bio-diversity.
