지난해 등장한 정보보호 관련 사건의 특징 중 하나는 금전적 이익을 목적으로 한 사이버 범죄가 본격적으로 등장했다는 점이다. 이런 유형의 범죄는 비단 국내뿐만이 아니라, 미국, 유럽 등 전 세계적인 관심사로 떠올랐다. 이런 의미에서 지난 10월 경찰청 주최로 개최된 '국제 사이버테러 대응 공동심포지움' 참석차 한국을 방문한 독일 BKA소속 Mirko Manske로부터 독일 및 EU 지역의 사이버 범죄 현황에 대한 의견을 들어봤다. Mirko Manske는 독일 연방 범죄 경찰국(Bundeskr-iminalant, BKA) 소속으로 지난 2006년부터 국내 경찰청 사이버테러대응센터에 해당하는 BKA 내 National High Tech Crime Unit(NHTCU)의 정보분석 및 수집 전문가로 활동하고 있다

독일의 지리학자 Ferdinand F.Von Richthofen(1833-1905)의 $\boxDr$China$\boxUl$ (1877)에서 비단길(Seidenstrassen-영역 silk road) -동서 교통의 역사를 개관하고서 중국과 서툴키스탄 및 북서 인도와의 silk 무역을 매개한 중앙아시아 경유의 길을 일렀음. 리히트호펜에서 한걸음 나아가, 1910년 독일 지리학자 알벨트헬만 (Albert Herrmann)은 한 대(BC 114 - AD 127의 견의 최대의 판로의 하나가 시리아였음을, 들어, 내륙 아시아 및 이란을 경우 중국에 이르른 통로를 추가함.

This paper discuss some properties of non-monotonic fuzzy measures of Ф -bounded variation. We show that there is an example of Ф such that $\beta$V(x, F) is a proper subspace of Ф$\beta$V(x, F) And also, we prove that Ф$\beta$V(x, F) is a real Banach space. Furthermore, we investigate some properties of non-monotonic fuzzy Ф -measures.

최근 세계경제의 성장이 둔화될 조짐을 보이고 있으나, 우리 경제에 대한 전망은 비교적 밝은 편이다. 우리의 주요 수출 대상국인 신흥개도국의 수요가 증가세를 유지하고 있고, 국내 투자가 회복되고 있기 때문이다. 그러나 이러한 수츨호조와 매출 및 순익의 증가는 비단 우리 기업에만 국한된 현상은 아니다. 세계 경제가 지난 4년간 1980년대 이후 최고의 성장세를 보였고 세계 교역 규모가 증가하면서 각국 제조업체의 수익은 큰 폭으로 증가하였다. 특히 1985년 이후의 엔고를 극복하고 1991년 이후의 장기 불황에서 벗어난 일본 경제는 전후 최장의 성장세를 시현하고 있다. 일본 제조업을 대표하는 일본 자동차업계 역시 양적으로 뿐 아니라 질적으로도 세계 최고의 경쟁력을 확보해 나가고 있다. 본 고에서는 일본자동차산업의 엔고와 장기불황 극복 전략에 대해 살펴 보기로 한다.

미국, 중국 등에 이어 국내에서도 KT에서 2021년 7월 5G 단독모드(StandAlone)를 상용화 하였다. 5G 비단독모드(Non-StandAlone)에서는 다년간 사용되었던 기존 LTE(Long Term Evolution) 망의 장비를 재활용하기 때문에 신규 장비의 도입은 5G 기지국으로 제한된다. 그러나 5G 단독모드에서는 새롭게 정의된 5G 장비들을 사용하기 때문에 이에 대한 위협 분석과 보안 기능의 정의에 따라 각 장비에 보안의 구현이 제대로 되어 있는지 검증하는 절차가 요구된다. 이러한 환경에서 본 논문은 5G 단독모드 기기의 보안 인증 현황을 제공하고자 한다.

Histopathological changes in gills by potassium permanganate were investigated in four fish species. flounder(Pararychthys olivaceus) and rockfish(Sebastes schlegeli) in marine fish, and carp(Cyprinus carpio) and eel(Anguilla japonica) in freshwater fish. Marine fishies were more sensitive to $KMnO_4$ than freshwater fishies and have shown histological changes even in low concentration of 1ppm. Eels were less affected than carp in high concentration of $KMnO_4$. Especially in eels, hyperplasia and hypertropy of mucus cells were observed. Compared to in underground water. the effect of KMnO₄ were reduced very much in pond water. That this differences were due to the concentration of organic substances were certained by experiment with various feed concentrations. The potency of $KMnO_4$ were influenced by dissolved oxygen.

In this paper, the operating thermal characterictics of liquid-ice was expeimentally investigated in an adiabatic and a non-adiabatic direct contact liquid-ice heat exchanger. Experiments were carried out varing inlet temperature, Ice Packing Factor, and the flow rate of heat transfer fluid. The higher inlet temperature and the more much inlet flow rate, thermal stratification in liquid-ice heat exchanger was established faster. In the case of adiabatic ice storage tank, temperature distribution was a little higher at all conditions than that of non-adiabatic one. The ratio of latent energy to total discharge energy($E_{\lambda}/E_[tot}$) was about 80%, and the discharge of latent heat energy was appeared rapidly as inlet temperature and flow rate were higher.

The experiments were carried out to investigate the aging effect between loin muscles from Hanwoo and Helstein. Two kinds of loin samples were prepared from the carcasses of grade B2 from Hanwoo and D from Holstein. The carcasses were chilled for 24 hours after slaughter. The carcasses was obtained by chilling the loin fort 1 day after wrapping it. On the other hand. was obtained divided by 500g and stored at 2$^{\circ}C$ for 11 days after air packing. In the case of fresh beef pH and lactic acid of grade B2 were lower than that of grade D. Hardness and chewiness of grade B2 were lower than that of grade D, but myofibrillar fragmentation index(MFI) of glade B2 were higher than that of grade D. Total concentrations of free amino acid of grade B2 were higher than those of D. The contents of monounsaturated fatty acid of grade B2 was lower than grade D, and monosaturated fatty acid/saturated fatty acid(MUFA/SFA) of grade B2 were higher than grade D. The contents of nonprotein nitrogen of the aged beef was higher than the fresh beef, and beef of grade B2 was higher than that of grade D. In case of aging beef. cooking loss of grade B2 was lower than grade D.

The morphological characters and scientific names of Korean Artemisia sect. Absinthium were reviewed based on the type specimen, the original description, observation of the living materials and voucher specimens. The form of the habitat, the structure of underground, the leaf shape and capitulum features were valuable characters in identifying the taxa. The sect. Absinthium in Korea was classified as three taxa of A. sieversiana, A. lagocephala, A. fauriei. The illustration and description of each taxa were provided. Particularly, A. fauriei in this section with hair on receptacle and A. fukudo in sect. Abrotanum without hair on receptacle grow in mixed groups on the West shore of Korea. Two species with populations which grow in mixed groups, was observed as being putative hybrid individuals based on morphological characters.

In this paper, we design and implement an efficient bulk-loading algorithm for CIR-Tree. Bulk-loading techniques increase node utilization, improve query performance and reduce index construction time. The CIR-tree has variable size of internal node entries since it only maintains minimal dimensions to decriminate child nodes. This property increases fan-out of internal nodes and improves search performance. Even though several bulk-loading algorithms for multi/high-dimensional index structures have been proposed, we cannot apple them to CIR-tree because of the variable size of internal node entries. In this paper, we propose an efficient bulk- loading algorithm for CIR-tree that improves the existing bulk-loading algorithm and accomodates the property of CIR-tree. We also implement it on a storage system MiDAS-III and show superiority of our algorithm through various experiments.
