Until recently, molecular detection method for Bursaphelenchus xylophilus (Bx) infesting pine trees and killing themhas been developed several ways such as RFLP, Real-time PCR and LAMP. However, these were not only time-consumingprocess but also could not confirm the result in a short time. Furthermore, these methods also need thermo cycler orthermostat which are not portable and inexpensive. For above reasons, we had been developed the detection method forBx remaining in the pinewood chips without using electronic devices. In this study, we had used DUNT buffer that isable to extract genome DNA from Bx in the pinewood within 10 min and isothermal amplification that could be amplifiedthe specific DNA fragment of Bx at 37 ℃ for 10 min. As a result, our method is able to confirm the presence or absenceof Bx in pine trees within 20 min and could be used in the field as it does not require the electronic devices.

In fabricating plasma display panels, the photolithographic process is used to form patterns of barrier ribs with high accuracy and high aspect ratio. It is important in the photolithographic process to control the refractive index of the photosensitive paste. The composition of this paste for photolithography is based on the B2O3-SiO2-Al2O3 glass system, including additives of alkali oxides and rare earth oxides. In this work, we investigated the density, structure and refractive index of glasses based on the B2O3-SiO2-Al2O3 system with the addition of Li2O, K2O, Na2O, CaO, SrO, and MgO. The refractive index of the glasses containing K2O, Na2O and CaO was similar to that of the [BO3] fraction while that of the SrO, MgO and Li2O containing glasses were not correlated with the coordination fraction. The coordination number of the boron atoms was measured by MAS NMR. The refractive index increased with a decrease of molar volume due to the increase in the number of non-bridging oxygen atoms and the polarizability. The lowest refractive index (1.485) in this study was that of the B2O3-SiO2-Al2O3-K2O glass system due to the larger ionic radius of K+. Based on our results, it has been determined that the refractive index of the B2O3-SiO2-Al2O3 system should be controlled by the addition of alkali oxides and alkali earth oxides for proper formation of the photosensitive paste.

For microelectronic circuits, the main type of failure is thermal fatigue. Therefore, the search for matched coefficients of thermal expansion (CTE) of packaging materials in combination with a high thermal conductivity is the main task for developments of heat sink materials electronics, and good mechanical properties are also required. The aim of this work is to develop copper matrix composites reinforced with carbon nanofibers to meet these requirements. In this paper, a technology for obtaining a homogeneous mixture of copper and nanofibers will be presented and the microstructure and properties of consolidated samples will be discussed.

This is a treatise on the legality of the practice of attaching the crime counts exhibit as the part and parcel of the indictment or information (hereinafter referred to as ‘indictment’). Recently, the Korean Supreme Court decided the exhibit will not be considered as a part of the indictment. In Korea, it became conventional that the prosecution attached the exhibit of the crime counts stored in CD-ROM because the printout of the voluminous crime counts, such as those of the copyright infringement and the privacy infringement, bloats to the tune of several millions and tens of million pages. But this time, the Supreme Court decided that this kind of practice is not tenable anymore. But this decision of the Supreme Court seems at odds with the plain interpretation of the current criminal procedure law because ‘whatever is attached to the content of the indictment constitute a part of the whole indictment’ is the literal construction of the text of law. Moreover, it is strange to render it illegal when indictment attach the footnote that the crime count is so voluminous that the specifics will be appended in the CD-ROM format and actually appends the crime counts exhibit. It is not only illogical but also impractical to interpret that the appended crime exhibit is out of the scope of the indictment or is overstepping the bounds of the court hearing. It is well known that, in certain types of crime, such as the copyright infringement or the privacy infringement, crime counts exhibit extend to tens of thousand pages. If we stick to the traditional notion that all the crime counts should be presented in the physical document format, it will be not only impractical but also tremendous waste of efforts and expenses. If we take into account the recent development that the electronic document usage steadily replacing the paper document usage in civil and criminal justice system and peoples are sufficiently accustomed to the data storage devices, providing the crime counts exhibit in the form of electronic storage will be conducive to enhancing the interest of the defense if we take into account that it is time-saving and efforts-saving to analyze and archive the case record in the electronic platform. It is the right time to revise the criminal procedure law to avoid the controversy on the permissibility of the presenting the crime counts exhibit in the form of the electronic storage. It will be desirable to allow the prosecution to present the crime counts exhibit in the form of electronic storage unless it will curtail the right of the defendant and if it will meet the practical necessity of the court to authenticate the crime counts of the indictment.

이 논문에서는 안전한 해양레저 행위를 지원하기 위한 두 가지 개인 휴대용 전자장치 개발 내용을 기술한다. 하나는 조난자를 신속히 민-관-군 동시 다발적으로 수색하기 위한 선박용 9GHz 대역의 일반 레이더 전파에 응답하는 레이더 응답장치이다. 다른 하나는 조난자의 위치를 추적하고 식별할 수 있는 900MHz 스펙트럼 확산 주파수 홉핑 방식의 송수신기와 GPS를 이용한 해상 무선식별장치 개념의 전자장치이다. 해양경찰 함정을 이용한 해상에서의 다양한 현장실험을 통하여 두 가지 장비의 성능을 확인하였다. 그리고 향후 상용화 방안에 대해서 검토하였다.
