In this paper, optimum design of distributed detection is considered for a parallel sensor network system consisting of a fusion center and multiple passive sonar nodes. Nonrandom fusion rules are employed as the fusion rules of the sensor network. For the nonrandom fusion rules, it is shown that a threshold rule of each sensor node has uniformly most powerful properties. Optimum threshold for each sensor is investigated that maximizes the probability of detection under a constraint on energy consumption due to false alarms. It is also investigated through numerical experiments how signal strength, false alarm probability, and the distance between three sensor nodes affect the system detection performances.

In this paper, optimum design of distributed detection is considered for a parallel sensor network system consisting of a fusion center and two passive sonar nodes. AND rule and OR rule are employed as the fusion rules of the sensor network. For the fusion rules, it is shown that a threshold rule of each sensor node has uniformly most powerful properties. Optimum threshold for each sensor is investigated that maximizes the probability of detection under the constraint of a specified probability of false alarm. It is also investigated through numerical experiments how signal strength, false alarm probability, and the distance between two sensor nodes affect the system detection performances.

Kinds of Jusul-do praying for sons are found in Yeocheon Area in Southern District, where people had great desire for flourishing posterity and phallicism prevailed in agricultural and fishery culture. Religious idea of praying for sons among commoners is deeply related to beliefs wishing for blessing spontaneously developed along with Animism, Totemism, and Shamanism originated from primitive religion and then transferred into folk religion. Magic symbols of seeking fortune, health, longevity, wealth, good luck, exorcising evil spirits, desiring sons, and flying dragons from legends, folklore, fortune-telling, cult of nature, praying for sons, and living in community (of farming villages, fishing shores, and mountain villages) are abundantly and majestically depicted in the 8-panel folding screen consisting of eight Korean folk painting; Yonhwajeong-do ((龍華亭圖), Sangbongjeong-do(翔鳳亭圖),Gyeongyangdae-do(景釀臺圖), Bangujeong-do(伴鷗亭圖), Hapgangjeong-do(合江亭圖), Changamru-do(滄巖樓圖), Ssangbongjeong-do(雙鳳亭圖), and Hansansa-do(寒山寺圖). It is supposed that Gija-jusul-do must have been hung up in bedrooms for the newly married couples, or rooms for womenfolks for decoration. This must have been considered significant as a son to be born there was counted to be essential for succession and prosperity of a family and blood. Having many sons meant to be filial and loyal insuring labor power for agricultural community, producing force for national defense, and offering brain in court to assist the ruler in the future.

Something to do to practice filial piety for a descendant of the family was supposed to bear and bring up sons to advance to court to assist the ruler, and to be esteemed by others. With sincere heart expecting a child and desiring a son, someone would get spiritual comfort and develop patience somewhere in the area praying ardently before a folding screen of this Gija-jusul-do.

In this paper, modeling and design of a distributed detection system are considered for an active sonar sensor network. The sensor network has a parallel configuration and it consists of a fusion center and a set of receiver nodes. A system with two receiver nodes is considered to investigate a theoretical aspect of design. To be specific, AND rule and OR rule are considered as the fusion rules of the sensor network. For the fusion rules, it is shown that a threshold rule of each sensor node has uniformly most powerful properties. Optimum threshold for each sensor is obtained that maximizes the probability of detection given probability of false alarm. Numerical experiments were also performed to investigate the detection characteristics of a distributed detection system with multiple sensor nodes. The experimental results show how signal strength, false alarm probability, and the distance between nodes in a sensor field affect the system detection performances.

이 논문에서는 한 쌍의 수동 광대역 소나로 구성된 병렬구조 분산센서망에 적용할 수 있는 에너지 인식 분산탐지 체계의 설계 및 성능분석에 대해 검토한다. 이 분산탐지기는 융합규칙으로 AND 규칙과 OR 규칙을 사용하였다. 이 경우 각 센서노드의 문턱값 규칙은 전체 분산센서망의 탐지확률을 최대로 하는 UMP(uniformly most powerful)임을 증명하였다. 그리고 소나 체계에서 오경보에 의해 발생하는 에너지 비용을 제한 조건으로 주었을 때, 탐지확률을 최대화하는 센서노드의 최적 문턱값이 갖는 특성을 이론적으로 검토하였다. 나아가 신호 강도, 에너지 비용에 대한 제한조건, 센서노드 사이의 간격등이 탐지성능에 미치는 영향을 수치실험을 통해 분석하였다. In this paper, optimum design of energy-aware distributed detection is considered for a parallel sensor network system consisting of a fusion center and two passive sonar nodes. AND rule and OR rule are employed as the fusion rules of the sensor network. For the fusion rules, it is shown that a threshold rule of each sensor node has uniformly most powerful properties. Optimum threshold for each sensor is investigated that maximizes the probability of detection under a constraint on energy consumption due to false alarms. It is also investigated through numerical experiments how signal strength, an energy constraint, and the distance between two sensor nodes affect the system detection performances.

Among fatty acids, omega-3 and omega-6 fatty acids are called polyunsaturated fats because they have several double bonds. Both are biologically active and play an important role in immune system and metabolism processes in the body. The intake of omega-3 and omega-6 fatty acids in a ratio of 1:4–5, which is recommended by the World Health Organization for a balanced nutrition, can help prevent the onset of insulin resistance, depression, high blood pressure, stroke, and obesity. However, in modern diets, people consume too much omega-6 fatty acids. One reason is the consumption of mostly vegetable oils, which contain a high amount of omega-6 fatty acids. We hypothesized that a proper mix of oil extracted from pine nuts and general oils could provide the desirable functional benefits through ensuring a 1:4–5 ratio of omega-3 to omega-6 fatty acids. Therefore, this study investigated whether mixing pine nut oil with general oils could provide the ideal composition ratio of 1:4–5 of omega-3 to omega-6 fatty acids. Perilla, hazelnut, olive, avocado, and hemp seed oils were selected as the candidates for mixing with pine nut oil. The individual profiles of fatty acids and the omega-3:omega-6 fatty acids ratio in the mixtures were analyzed using a GC-FID system. Our results showed that the mixture of 85% pine nut oil and 15% perilla oil had an optimal omega-3 to omega-6 fatty acids ratio of 1:4–5. These findings suggest that the proportioned mixture of pine nut oil and perilla oil has the potential to develop oil blends with improved functionality.
