원격지에 위치하고 있는 전등을 효율적으로 관리하기 위해서는 전등이 설치된 장소의 상태 또는 전등의 상태를 파악해야 한다. 그러나 기존의 네트워크 연결이 없는 센서 기반의 전등은 센서의 정보가 일률적이고 센서 정보를 중앙에 알릴 수 있는 방법이 없기 때문에 관리가 어려운 문제점이 있었다. 이 논문에서는 2가지 이상의 센서를 이용하여 전등의 다양한 상태 정보를 획득하는 관리시스템을 제안한다. 중앙에서 상태 정보를 얻기 위하여 지그비 기반의 무선 네트워크를 사용한다. 이 시스템은 다양한 센서 정보를 제공함으로써 관리자의 의사결정을 신속화할 수 있는 장점을 제공한다.

Together with the concern about the indoor air quality as sick house syndrome, the Ministry of Environment announced "Indoor Air Quality Control Law for the Multi Purpose Facility," which made the interests to be focused in the urgent understanding of current condition and preparation of measures about the indoor air pollution. The law was revised to obligatorily notify the amount of Formaldehyde and Volatile Organic Compounds in the case of newly constructed apartments with more than 100 houses. School also have its own indoor air quality guideline. Indoor air quality in school is very important because, children who very weak to indoor pollutants reside long time in there. The purpose of this paper is to to survey indoor air quality in school by field measurement. Field measurements were performed in 11 schools which were selected from 3 major cities(Incheon, Dae-jeon, chuncheon) in korea, Totally concentration of indoor pollutants were determined in 32 classroom. Target air pollutants were TVOC, formaldehyde, dust, CO, CO2. For the result of this investigation, Indoor air quality in classroom was very poor and it was found that some pollutants(TVOC, float bacteria) exceed the guideline.

This article explored the customers protection regulations in electronic payment system by Article 4A of the UCC and EFTA of 1978 and by Electronic Financial Transaction Act of Korea. Both Korea and America have various regulations to protect concerned parties(customers). For examples, the errors of payment order, money-back guarantee, and unauthorized payment order etc. First, this Article focuses on the allocation of risk of loss caused by ambiguous term in payment orders that do not express the subjective intention of the senders. Second, most rights and obligations created by Article 4A of America can be varied with the agreement of affected parties. But there are some exceptions. The exceptions include the money-back guarantee. So Receiving bank have to pay to originator the ordered money included interest. However, Korea also has money-back guarantee but bank do not pay interest to sender. Lastly, Electronic Funds Transfer Act of 1978 and Regulation E has US$ 50 regulation in order to protect customers on the unauthorized payment order. Article 4A imposes duty to detect unauthorized payment orders to originator in relation to the establishment of commercially reasonable security procedure, while Korean law imposes the duty to notify the bank in order to decrease the loss resulted from unauthorized payment order.

This paper introduces a implementation of fault detection for national highway line 3. Fault detection system was installed and operated on national highway line 3, environmental elements caused by abnormal status or faults has often happened. Therefore, the function of fault detection system is to speedy notify fault site, cause as well as scale of fault to manager. Though the fault detection and diagnosis system has been imported in the field of process of water and electric power, it is just beginning step in the field of ITS(Intelligent Transportation Systems). In general, Maintenance system is performed the online/offline process of detection, diagnosis and measure. This paper is studied online detection process, which is realtime remote detection.

In the scalable video coding standard, inter-layer prediction based on the coding information of the base layer was adopted to increase the coding performance. This prediction tool results in new syntax elements called motion_prediction_flag (mPF) and residul_prediction_flag(rPF), which are carried to notify the motion vector predictor (MVP) and reference block required in the motion compensation of the decoder. In this paper, an efficient coding method for mPF is proposed to enhance coding efficiency of the salable video coding standard. Through an analysis on the transmission of mPF based on the relationship between the MVPs, we discover the conditions where mPF is unnecessary at the decoder and suggest a modified rate-distortion (RD) cost function to make RD optimization more effective. Simulation results show that the proposed method offers BD rate savings of approximately 1.4%, compared with the conventional SVC standard.

If see CISG's passing of risk and altered regulations first, when sales contract accompanies transport of goods and seller does not have duty to deliver goods at particular place, when deliver to the first carter to send to purchaser according to sales contract risk passes to purchaser, and when there is duty that seller must deliver goods to carter at specification place, when goods are delivered to carter at same place, risk does not pass to purchaser. Second, risk about transporting goods passes to purchaser at signing a contract. But, when there is special assessment, risk passes to purchaser when goods are delivered to carter who publish document that embody contract of carriage. Nevertheless, it is loss if seller did not notify this truth to occasion purchaser who could knew loss or damage of goods or know justly at sales contract conclusion defamation danger seller of be burdensome. Third, seller has responsibility about damage or loss as long as hide in own artificiality or forbearance after risk passes to purchaser. Regulation about risk in Incoterms 2010 was separated into 11 condition, and move time of risk differs in angle condition. It is appeared that the substance handles relatively comprehensively because compare in Incoterms 2010 although it is because it becomes if it examines regulation about deliver and passing of risk of goods setting in CISG relatively concise. Also, segments that can become posibility of analysis controversy exist.

Stress adversely affects the wellbeing of commercial chickens, and comes with an economic cost to the industry that cannot be ignored. In this paper, we first develop an inexpensive and non-invasive, automatic online-monitoring prototype that uses sound data to notify producers of a stressful situation in a commercial poultry facility. The proposed system is structured hierarchically with three binary-classifier support vector machines. First, it selects an optimal acoustic feature subset from the sound emitted by the laying hens. The detection and classification module detects the stress from changes in the sound and classifies it into subsidiary sound types, such as physical stress from changes in temperature, and mental stress from fear. Finally, an experimental evaluation was performed using real sound data from an audio-surveillance system. The accuracy in detecting stress approached 96.2%, and the classification model was validated, confirming that the average classification accuracy was 96.7%, and that its recall and precision measures were satisfactory.
