Since wireless sensor networks are deployed in open environments, an attacker can physically capture some sensor nodes. Using information of compromised nodes, an attacker can launch false data injection attacks that report nonexistent events. False data can cause false alarms and draining the limited energy resources of the forwarding nodes. In order to detect and discard such false data during the forwarding process, various security solutions have been proposed. But since they are prevention-based solutions that involve additional operations, they would be energy-inefficient if the corresponding attacks are not launched. In this paper, we propose a detection method that can detect false data injection attacks without extra overheads. The proposed method is designed based on the signature of false data injection attacks that has been derived through simulation. The proposed method detects the attacks based on the number of reporting nodes, the correctness of the reports, and the variation in the number of the nodes for each event. We show the proposed method can detect a large portion of attacks through simulation.

농산물 경쟁력확보를 위한 농산물 지역정보망 구축모형의 개발

이해영,조덕호 ( Hae Young Lee,Deuk Ho Choi ) 한국지방자치학회 1996 한국지방자치학회보 Vol.8 No.2

Korean agricultural information systems had been built by a sypply strategy. The Ministry of Agriculture established local agricultural information network for the structure of rural information infrastructure, for the information welfare to the rural farmers, and for the balancing the technological gap between urban and rural information society. The central government employed the supply-side approach, by which the information system itself can create end-users` satisfactions and benefits. In practice and retrospect, this building strategy was destined to be unsuccessful because supplies cannot create information demands, and because supplies themselves did not adjust to the end-users` information needs and participations. By reviewing prototype-model and user-participation paradigm, and by combining these two models into a demand-side approach, this article articulately delineated a user-satisfaction prototype model that it can bring information demands and data-base needs issued from the end-users into the information system building. This building model can sign off to the point of the user-maximized satisfaction levels, and in turn increase the market competitiveness of local agricultural products. Also this user-friendly model can accommodate and determine the final up-points of the user-satisfaction that can be influenced by the moderation variables such as user-developer communication, user-participation pattern, farmers` computerization, information task and system itself complexity, and quality and quantity of data-base. The nex step for the further research subject might be an empirical application and test of this model into the building of the local agricultural information systems.

설회소성용 Rotary kiln에서 필요 연류량의 설정값 산정용 Fuzzy 판단자의 설계

This paper presents a design of the fuzzy decision maker which infers set value for fuel rate in the rotary kiln of making CaO. The fuzzy decision maker proposed are divided into two groups whose functions are different each other. The one operates when production demand is constant. The other deals with the status of varying production demand. We have chosen several variables used for composing condition and action part by investigating ingerent features of the rotary kiln and skilled operators`manual method of inferring fuel rate. Membership function of each variable was designed by analyzing experimental data and field data collected during two months. On-line operation with fuzzy rules suggested was done safely like human operators' action.

수산자원 증강을 위한 방류용 종묘로서 연안 정착성 어종인 조피볼락의 종묘성 강화와 우량종묘의 판정기법에 대한 기초적 연구를 위하여 서해안 윽상수조산, 축제식 양식산 및 자연산 조피볼락 치어에 대한 일반성분, 비만도, 간중량지수, 복강내지방, 장중량지수, 근육중량비, 일반 아미노산 함량 및 무기질 함량을 비교하였다. 수분 함량은 자연산이 양식산 (축제식 망식산과 육상수조산) 보다 높게 나타났지만 지질함량은 자연산이 가장 낮았다. 회분 함량은 자연산이 양식산(축제식 양식산과 육상수조산) 보다 높았다. 치어 전어체에서 단백질함량의 차이는 없었다. 비만도는 육상수조산이 자연산보다 높은 값을 보였지만 축제식 양식산과는 유사하였다. 간중량지수 (HSI), 복강내지방 (IPF) 및 장중량지수 (ISI)에서 육상수조산과 축제식 양식산은 차이가 없었으나 자연산보다 높은 값을 나타내었다. 근육중량비는 사육방법에 따라 차이가 없었다. 일반아미노산 총함유량은 자연산이 육상수조산보다 높았으나 축제식 양식산과는 차이가 없었다. 자연산은 asparatic acid, glutamic acid, isoleucine, leucine, Iysine, phenylalanine, threenine, valine에서 양식산 (축제식 양식산과 육상수조산) 보다 유의적으로 높았다. 무기질 함량 중 Ca, P 함량은 자연산과 육상수조 양식산은 유사하였으나, 축제식 양식산보다 유의적으로 높게 나타났다. Mg 함량은 자연산이 가장 높았으며, Mn 함량은 자연산, 육상수조산, 축제식 양식산의 순서로 나타났다. 자연산의 Zn 함량은 육상수조산과는 유사하였으나, 축제식 양식산 보다는 높게 나타났다. 전체적으로 수분과 회분 함량, asparatic acid, glutamic acid, isoleucine, leucine, lysine, phenylalanine, threonine, valine과 일반아미노산 총함유량 및 Mg 함량은 자연산이 양식산 (축제식 양식산과 육상수조산) 보다 높게 나타났으며, 지질함량, Mn 함량과 비만도, 간중량지수 (HSI), 복강내지방 (IPF) 및 장중량지수 (ISI)에 있어서는 양식산이 자연산보다 높은 값을 보였다. Ca, P 및 Zn함량은 축제식양식산에서 가장 낮게 나타났다. 그러므로 이러한 체성분 및 생물학적 특성은 조피볼락 방류용 우량종묘의 판정과 종묘성 강화의 지표로서 적용이 될 수 있을 것이다. Cultured juvenile black rockfish, Sebastes schiegeli as a seed for sen ranching project were compared with the similar size of wild fish. Wild fish were analyzed and compared with cultured fish in body indices, and moisture, crude protein, lipid, ash, many kinds of amino acids and various minerals in the whole-body of juvenile rockfish from three different populations. There were significant (P<0.05) differences in the moisture, crude lipid, and ash in the whole-body of fish among three different populations; the moisture content of wild fish was higher than that of both cultured fish. The lipid content in wild and tank cultured fish was lowest and highest, respectively; The lipid content of fish cultured in embanked system was intermediate values. The condition factor (CE), hepatosomatic index (HSI), and intraperitoneal fat (IPE) of fish cultured in tank system and embanked system were significantly (P<0.05) higher than those of wild fish. But fish cultured in tank system produced similar intestinosomatic index (ISI) and muscle ratio (MR) values as the wild fish. There were significant differences in asparatic acid, glutamic acid, isoleucine, leucine, lysine, phenylalanine, threonine, valine of whole-body fish cultured by different methods; the wild fish was highest in these amino acids, followed by fish cultured in embanked system and then fish cultured in tank system. There were also significant differences in Ca, P, Mg, Mn, Zn of whole-body fish cultured by different methods: wild fish and fish cultured in tank system produced highest in Ca, P, Mg, Zn and lowest in Mn, respectively. There were significant differences in moisture, crude lipid, ash, many kinds of amino acids, several minerals, CE, HSI, UE, and ISI among the three juvenile populations; whole-body of wild fish showed higher in moisture, ash, asparatic acid, glutamic acid, isoleucine, leucine, Iysine, phenylalanine, threonine, valine, Ca, P, Mg, and Zn than fish cultured in embanked system, while they showed lower in the rest of the nutritious parameters studied.

Smartphone technology has spread rapidly around the globe. According to a report released by the Korea Information Society Development Institute, about 95% of Koreans aged more than 30 years old owned smartphones. Recently, blood pressure (BP) measurement using a photoplethysmography-based smartphone algorithm paired with the smartwatch is continuously evolving. In this document, the Korean Society of Hypertension intends to remark the current results of smartphone / smartwatch-based BP measurement and recommend optimal BP measurement methods using a smartphone device. We aim to increase the likelihood of success in implementing these new technologies into improved hypertension awareness, diagnosis, and control.
