BACKGROUND:This study was conducted to investigate residual organochlorine pesticides (ROCPs) in agricultural soils and crops. Agricultural soil samples and crop samples were collected from 93 cities and counties. METHODS AND RESULTS: Extraction and clean-up for the quantitative analysis of ROCPs were conducted by the modified quick, easy, cheap, effective, rugged, and safe (QuEChERS) method. Recovery and limit of detection (LOD) of ROCPs in agriculturalsoils and crops were 76.5-103.0 and 75.2-93.2%, 0.01-0.08 and $0.10-0.15{\mu}g/kg$, respectively. Detected ROCPs in agricultural soils were ${\alpha}$-endosulfan, ${\beta}$-endosulfan, and endosulfan sulfate, the residue were 2.0-12.0, 1.2-53.1, and $2.2-329.8{\mu}g/kg$, respectively. But these pesticides in all green perilla leaf and green pepper samples were not detected. CONCLUSION: These results showed that ROCPs residues in agricultural soils were not as high as crop safety threatening.

Recently, according to the number of internet in widely use and the development of the related application program, the distribution and use of multimedia content(text, images, video, audio etc.) is very easy. The Picture Archiving and Communication System(PACS) was introduced for computerization of medical system and telediagnosis between the hospital. It is becoming more and more possible to create, store, and transmit medical images via PACS. There has been a growing interest in protecting Medical images with an enormous amount of information. This paper proposes an algorithm that utilizes both JPEG 2000 and robust watermarking for medical images. With the proposed algorithm, it takes considerably less time to do JPEG 2000 and watermarking than when they are done separately. Based on the experiment results, it takes 0.72 second for the proposed algorithm and 1.11 second when they are done separately. We confirmed that the proposed algorithm was more faster than when they are done separately.

The fingerprint information can cause serious problems when it has been compromised. Because it's a limited biometrics. Recently, there is an increasing study of the fuzzy fingerprint vault system to protect fingerprint information. The study on the problem of fingerprint alignment using geometric hashing technique carried out. This paper proposes a hardware architecture fuzzy fingerprint vault system based on geometric hashing. The proposed architecture consists of software and hardware module. The hardware module has charge of matching between enrollment hash table and verification hash table. We also propose the hardware architecture using parallel process for high-speed process of fuzzy fingerprint vault. Based on the experimental results, the execution time of the proposed system with 36 real minutiae is 0.24 second when 200 chaff minutiae, 0.53 second when 400 chaff minutiae. In the same condition, we confirmed that the proposed system using parallel process takes 0.01 second and 0.03 second, respectively.

Palletizing task is necessary to promote efficiency of keeping and shipping task. This is, however one of the most monotonous and heavy laborious work in the factory. That is why many types of Robot palletizing system have been developed. But many robot motion commands is still depends on the teach pendent. That is, the operator input the motion command line one by one. So we propose the new GUI Interface of Palletizing System that can be used more conveniently. To do this, we use the algorithm of PLP, Fast Algorithm and realize the 3D Auto-Patterning visualization using robot simulator.<br/> The usages of 3D pattern are following. First, an operator can identify the result of own task and edit it. Second, pass the position of object to a robot simulator. Using that position, palletizing operation can be simulated.

지문정보를 이용한 사용자 인증은 편리함과 동시에 강력한 보안을 제공한다. 그러나 유한개의 손가락 개수로 인해 패스워드처럼 변경을 자유롭게 할 수 없기 때문에 사용자 인증을 위해 저장된 지문정보가 타인에게 도용된다면 심각한 문제를 일으키게 된다. 지문정보를 안전하게 보호하기 위한 지문 퍼지볼트 시스템에 대한 연구가 활발히 진행되고 있다. 또한, 기하학적 해싱 기법을 적용하여 지문 정렬 문제를 해결하려는 연구도 진행되었다. 본 논문에서는 기하학적 해싱 기반 지문 퍼지볼트 시스템의 하드웨어 구조를 제안한다. 제안한 구조는 소프트웨어 모듈과 하드웨어 모듈로 통합 구성된다. 하드웨어 모듈은 등록 해시 테이블과 인증 해시 테이블의 변환 특징점의 정합을 담당한다. 실험결과, 제안한 하드웨어 구조의 수행 시간은 지문 특징점의 수가 36개이고 거짓 특징점의 수가 100개 일 때 0.2초, 400개 일 때, 0.53초이다. The user authentication using fingerprint information not only provides the convenience but also high security. However, the fingerprint information for user authentication can cause serious problems when it has been compromised. It cannot change like passwords, because the user only has ten fingers on two hands. Recently, there is an increasing research of the fuzzy fingerprint vault system to protect fingerprint information. The research on the problem of fingerprint alignment using geometric hashing technique carried out. This paper proposes the hardware architecture fuzzy fingerprint vault system based on geometric hashing. The proposed architecntre consists of software and hardware module.
