최근 웹의 급속한 발전으로 인하여 서로 다른 어플리케이션간의 비즈니스 통합 및 상호운용성이 요구되고 있으며, 이를 위해 표준 데이터 포맷인 XML(Extensible Markup Language)을 사용하여 플랫폼과 프로그래밍 언어에 독립적인 Web Services가 등장하였다. 이러한 가운데 Mobile과 RFID(Radio Frequence Identification) 응용 서비스같이 빠른 속도의 통신을 필요로 하는 분야들에서 원활한 서비스를 위해 텍스트 기반의 XML 데이터가 아닌 바이너리(binary) 데이터 전송을 하는Fast Web Services가 주목을 받고 있다. 이에 본 논문에서는 ITU-T(International Telecummnication Union - Telecommunication)와 ISO(International Organization for Standardization)/IEC(International Electrotechnical Commission)의 공동 표준으로 데이터 변환의 중간자 역할을 해주는 ASN.1(Abstract Syntax Notation One)에 대하여 알아보았다. 그리고 Web Services의 기본 메시지 전송방식인 SOAP(Simple Object Access Protocol) 메시지를 바이너리 데이터로 변환하기 위한 인코딩에 관하여 연구하였다.

In the process of simplifying the complex fate of the plant into a binary state, the information loss is inevitable. To minimize the information loss, the quantification of plant safety status has been formulated through the combination of the probability density function arising from the sensor measurement and the membership function representing the expectation of the state of the system. Therefore, in this context, the safety index is introduced in an attempt to quantify the plant status from the perspective of safety. The combination of probability density function and membership function is achieved through the integration of the fuzzy intersection of the two functions, and it often is not a simple task to integrate the fuzzy intersection due to the complexity that is the result of the fuzzy intersection. Therefore, a methodology based on the Algebra of Logic is used to express the fuzzy intersection and the fuzzy union of the arbitrary functions analytically. These exact analytical expressions are then numerically integrated by the application of Monte Carlo method. The benchmark tests for rectangular area and both fuzzy intersection and union of two normal distribution functions have been performed. Lastly, the safety index was determined for the Core Reactivity Control of Yonggwang 3&4 using the presented methodology.

Transformation of cantaloupes with the coat protein (cp) gene of papaya ringspot virus type W (PRSV-W), Thai isolate, was used to introduce virus resistance. Binary vectors containing either the full length coat protein coding region under control of the 35S CaMV promoter(pSA1175), or the inverted-repeat of a coat protein coding region (pSA1304), were constructed and used for Agrobacteriummediated transformation of cotyledonary explants of the cantaloupe cultivar Sun Lady. Four independent transgenic lines were obtained using pSA1304 and one using pSA1175. Integration of the PRSV-W cp gene into the genome of these transgenic lines was verified by PCR amplification, GUS assays and Southern blot hybridization. In vitro inoculation of these lines with PRSV-W revealed that whereas the line containing pSA1175 remained sensitive, the four lines containing pSA1304 were resistant. The presence of small RNA species, presumably siRNA, corresponding to regions of the viral cp gene in transgenic lines resistant to PRSV-W supports the involvement of post-transcriptional gene silencing in the establishment of resistance.

Agrobacterium-mediated gene transfer has recently been developed to improve rice transformation. In this study, 3 different transformation methods were tested including soaking, co-cultivation, and vacuum infiltration. Agrobacterium tumefaciens GV3101 harboring the binary vector pGreen:: LeGSNOR was used in this experiment. This study aimed to identify the most appropriate method for transferring LeGSNOR into rice. Vacuum infiltration of the embryonic calli for 5 min in Ilpum resulted in high transformation efficiency based on confirmation by PCR, RT-PCR, and qRT-PCR analyses. In conclusion, we described the development of an efficient transformation protocol for the stable integration of foreign genes into rice; furthermore, the study results confirmed that PCR is suitable for efficient detection of the integrated gene. The vacuum infiltration system is a potentially useful tool for future studies focusing on transferring important genes into rice seed calli, and may help reduce time and effort.

웹서비스는 서로 다른 플랫폼간의 통합을 가능하게 하였으나, 네트워크 환경이나 임베디드 시스템과 같이 상대적으로 느린 통신 매체에 자주 접속하거나 모바일과 같이 자원이 한정적인 소형 기기에서 사용 할 경우 전체 응용프로그램의 성능을 저하시키는 문제가 발생하고 있다. 이에 ITU-T(International Telecommunication Union - Telecommunication)와 ISO(International Organization for Standardization)/ IEC(International Electrotechnical Commission) 에서 공동으로 바이너리 XML 인코딩 표준을 제안하게 되었으며, 현재 진행 중인 바이너리 XML 인코딩 표준으로는 Fast Infoset과 Fast Schema가 있다. 본 논문에서는 웹서비스의 성능 향상을 위해 현재 표준화가 진행 중인 Fast Infoset 알고리즘과 Fast Schema 알고리즘을 도입하여 Fast XML 인코딩 시스템을 구현하였다. 또한, 구현된 Fast XML 인코더를 통하여 개발자나 사용자들이 Fast 웹서비스 시스템을 구축하는데 있어 참고 할 수 있는 테스트 베드를 제공한다.

Models of traditional Chinese medicine (TCM) are still difficult to grasp from the view of a Western-cultural background. For proper integration into science and clinical research, it is vital to think "out of the box" of classical sciences. Modern sciences, such as quantum physics, system theory, and information theory offer new models, that reveal TCM as a method to process information. For this purpose, we apply concepts of information theory to propose a "Chinese black box model," that allows for a non-deterministic, bottom-up approach. Considering a patient as an undeterminable complex system, the process of getting information about an individual in Chinese diagnostics is compared to the input-process-output principle of information theory and quantum physics, which is further illustrated by Wheeler's "surprise 20 questions." In TCM, an observer uses a decision-making algorithm to qualify diagnostic information by the binary polarities of "yang" (latin activity) and "yin" (latin structivity) according to the so called "8 principles" (latin 8 guiding criteria). A systematic reconstruction of ancient Chinese terms and concepts illuminates a scattered scientific method, which is specified in a medical context by Latin terminology of the sinologist Porkert [definitions of the Latin terms are presented in Porkert's appendix [1] (cf. Limitations)].

3D file formats typically include OBJ (Wavefront file format), STL (STereoLithography), and FBX (Filmbox). Each format has limitations depending on its configuration and usage, and supported formats are different depending on the software application. glTF helps uniform integration of 3D file formats and allows for more efficient transmission of large 3D geometry files by organizing them in a binary format. This paper presents explanation on OBJ, FBX, and STL which are major examples of existing 3D file formats. It also explains the concept and characteristics of glTF and compares its performance with other 3D file formats on the web. The loading time and packets of each 3D file format are measured according to the web browser environment by means of Google Chrome, Firefox and Microsoft Edge. Experimental results show that glTF is the most efficient and that it exhibits the best performance. As to STL, relatively excessive traffic was observed. This study is expected to contribute to reducing rendering time on the web as 3D file formats are used.

In 2015, the number of senior citizens aged 65 and over in Korea was 6,662,400, accounting for 13.1% of the total population. Along with these social phenomena, risk information related to the elderly is increasing every year. In particular, a fall accident caused by a fall can cause serious injury to an elderly person, so special attention is required. Therefore, in this paper, we implemented a system that monitors fall accidents and informs them in real time to minimize damage caused by falls. To this end, beacon-based indoor location positioning was performed and biometric information based on an integrated module was collected using various sensors. In other words, a multi-functional sensor integration module was designed based on Arduino to collect and monitor user's temperature, heart rate, and motion data in real time. Finally, through the analysis and prediction of measurement signals from the integrated module, damage from fall accidents can be reduced and rapid emergency treatment is possible. Through this, it is possible to reduce the damage caused by a fall accident, and rapid emergency treatment will be possible. In addition, it is expected to lead a new paradigm of safety systems through expansion and application to socially vulnerable groups.

압력변환 증류공정(Pressure-Swing Distillation, PSD)을 통해서 1-프로판올과 벤젠 이성분계 혼합물의 분리공정에 대한 전산모사 및 공정 최적화를 수행하였다. Schneider Electric사의 PRO/II with PROVISION V10.0을 사용하였으며, 열역학 모델식으로는 NRTL 액체 활동도계수 모델식을 적용하였다. 고압에서 저압 증류탑 배열 공정과 저압에서 고압 증류탑 배열공정에 대한 재비기의 총 heat duty의 소모량의 합을 서로 비교하였다. 유틸리티 소모량을 최소화하기 위해서 각 공정의 저압 증류탑과 고압 증류탑 상부 벤젠의 조성, 이론단수와 원료 주입단의 위치를 최적화하였으며, 각각의 증류탑의 환류비를 조절하였다. 공정 최적화 수행결과, 총 재비기 heat duty 값은 각각 고압에서 저압 증류탑 배열 공정의 경우 $3.10{\times}10^6kcal/h$ 이었으며, 저압에서 고압 증류탑 배열 공정의 경우 $2.75{\times}10^6kcal/h$로 나타났다. 또한, 저압-고압 증류탑 배열 공정에 열통합 공정(heat integration)을 적용한 경우 재비기의 총 heat duty 값이 고압-저압 증류탑 배열 공정에 비해서 약 57.36%정도 적게 추산되었다.
