  • The wave concept iterative procedure (WCIP) is used to analyze a quasi-square open metallic ring frequency selective surface (FSS). The quasi-square open metallic ring FSS is dual-polarized. When the incident plane wave is polarized in a direction parallel to the FSS' coupled parallel strips, it shows two rejecting bands. Moreover, another rejecting band can be obtained if the source plane wave is perpendicularly polarized with respect to the FSS' coupled parallel strips. The three resonant frequencies are inversely proportional to the length of the FSS' coupled strips to provide an easy fine tuning of the FSS structure. The simulated results obtained using WCIP are compared to the measured results, and a good agreement is reported.

  • A real-time inspection system is developed using line scan cameras. Several improved algorithms are proposed for real-time detection of defects in this automated inspection system. The major improved algorithms include the preprocessing, the threshold decision, and the clustering algorithms. The preprocessing algorithms are for exact binarization and the threshold decision algorithm is for fast detection of defects in 1-D binary images. The clustering algorithm is also developed for fast classifying of the defects. The system is applied to PCBs(Printed Circuit Boards) inspection. The typical defects in PCBs are pits, dent, wrinkle, scratch, and black spots. The results show that most defects are detected and classified successfully.

  • The running of the electric train are done by powering, breaking and coasting. Powering to start and accelerate the rolling stock means driving the three-phase electric induction motors controlled by VVVF inverters which are connected to overhead power line directly(DC) or indirectly(AC, DC/AC). Breaking is achieved by blending control which is the proportional combination between regenerative breaking of VVVF inverter and air pressure control of breaking operating unit(BOU). Therefore, Data obtained during two operation are very important items to evaluate the running performance of RS. This paper has investigated in real time data acquired from VVVF inverter and measured by pressure sensor directly connected to air breaking line(motor car and trailer car). By analyzing data in the region of time and frequency, fundamental methods for eavaluating the running performance of RS quantitatively and objectively have been suggested.

  • The wave concept iterative procedure (WCIP) is used to analyze arbitrarily shaped frequency selective surfaces (FSS). The WCIP method is developed from the fast modal transform based on a two-dimensional fast Fourier transform algorithm. Using the proposed procedure, less computing time and memory are needed to calculate the scattering parameters of the FSS structure. The method is applied to the modeling of an FSS structure of a rectangular patch and a comparison with experimental results confirms good agreement.

  • The shrinkage and the mechanical properties of polypropylene hybrid fiber reinforced mortar PHFRM were investigated in this study. Mortars were prepared with limestone crushing sand, Portland cement and polypropylene hybrid fibers PHF. Two types of virgin fibers, having the same length (30 mm) were used for reinforcing test mortars, fibers in diameter of 0.45 mm, used by PLAST BROS factory of Bordj Bou Arreridj (Algeria) for the fabrication of brooms (for household cleaning) and fibers in diameter of 0.25 mm, available on the market, having multiple applications. In this investigation, it was aimed to study the total and autogenous shrinkage, the flexural and compressive strength of mortars based on hybrid fibers. As a result, PHF have negatively affected the mortar workability. However, shrinkage risk was reduced and coarser fibers (PF45) were most effective for reducing shrinkage risk. The mechanical performances and the ductility of PHFRM were also enhanced.

  • In competitive political contexts, sustaining power is the ultimate goal for political parties. Nominating celebrity politicians can be a double-edged sword for parent brands in attracting votes and influencing voting intention. This study contributes to the moderating role of brand affinity towards celebrity politicians. It considers celebrities' cognitive perceived benefits and voting intention relationship in a multiparty parliamentarian election. A cross-sectional survey with a stratified proportional random sampling technique in fifteen Lebanese districts ensured a representative sample. One thousand two hundred sixty-nine responses were found eligible for analysis. Findings indicate that brand affinity positively moderates the negative relationship between perceived benefits and voting intention. This study offers a new understanding of celebrity politicians' implementation strategy and campaign management and considers the contribution of the affective intelligence theory. It provides implications, limitations, and promising directions for future research on celebrity politicians.

  • 지방 저장 종자의 발아 시 저장 지방의 유동은 떡잎이 스스로 광합성을 하기 전까지 탄소 에너지원을 공급하기 위한 핵심적인 대사과정이다. 본 연구에서는 오이 종자의 발아와 유식물의 발달 및 노쇠화 과정의 떡잎에서 식물성 카니틴의 검출과 변화를 처음으로 보고하고자 한다. 또한 오이 떡잎의 전 발달과정에서 불포화 지방산의 변화를 조사하였다. 카니틴은 오이 종자의 파종 후 3일째 떡잎에서 14.5 nM 수준으로 최고조에 달하며, 4일째에는 그 절반 수준인 7.2 nM 수준으로 급격하게 감소하였다. 이후 이어지는 3일 동안 7일째까지 카니틴은 ~3.0 nM 수준을 유지하였다. 같은 시기 불포화 지방산의 함량은 카니틴이 최고조에 달하는 파종 후 3일째 급격히 떨어지고, 5일째 저장 지방은 완전히 고갈되는 것으로 보인다. 파종 9일째부터 카니틴은 검출되지 않았으나 떡잎이 절반 노랗게 변한 노쇠화 중기의 떡잎에서 6.8 nM 수준으로 검출되었는데, 이 검출량은 오이 종자의 파종 후 저장 지방이 고갈되어가는 4일째 떡잎에서 검출된 카니틴의 양과 비슷한 수준이다. 파종 5일 이후 광합성 기능을 완전히 확보한 녹색 떡잎에서 불포화 지방산은 일정한 수준을 유지하며, 노쇠화 단계에 접어든 떡잎에서는 세포의 내막 구조물들이 파괴되며 또다시 불포화 지방산의 함량이 다소 증가하는 것을 관찰할 수 있었다. 이러한 카니틴과 불포화 지방산의 검출과 변화의 관찰은 오이 떡잎의 발달과정에서 밝혀진 최초의 발견이다. 이것은 오이 종자의 발아와 떡잎의 발달과정에 카니틴 대사와 관련 BOU 유전자 발현이 밀접하게 공조함을 확인한 것이다. 또한 오이 종자의 발아과정에 에너지를 공급하기 위한 글라이옥실산 회로와 더불어 부가적인 탄소원 이동의 경로의 가능성을 뒷받침한다.

  • 오이 씨앗의 발아는 세포의 지방체내 저장지방의 분해 결과인 acyl-CoA의 글라이옥시좀으로 이동 후 베타 산화의 결과물인 acetyl-CoA의 글라이옥실산 회로로의 유입과 지방의 유동으로 촉발된다. Acetyl-CoA는 글라이옥실산 회로의 가동을 위한 탄소원을 제공하며 시트르산과 말산을 생성하며 글라이옥실산 회로의 작동을 유도한다. 지방 저장 종자의 발아에 있어서 글라이옥실산 회로는 필수적 요소이며, 그 결과물인 말산 및 숙신산의 미토콘드리아로의 이동은 TCA 회로의 가동과 옥살초산의 생성 및 세포질로의 유동으로 PEPCK에 의한 당신생을 가능하게 한다. 즉, 저장 지방을 원료로 여러 대사물질의 생산 및 이동과 다중의 대사경로를 통하여 발아 시 사용 가능한 에너지원인 포도당의 형태로 전환이 이루어진다. 이에 동반하여 많은 유전자의 발현 조절이 이루어지고, 세포내 소기관 특히 미소체로 대표되는 글라이옥시좀은 말산 합성효소(malate synthase)와 이소 시트르산 분해효소(isocitrate lyase)로 특화된다. 또 다른 acetyl-CoA의 유동은 carnitine을 매개로 하는 BOU (A BOUT DE SOUFFLE)의 작동이다. 이것은 카니틴의 대사와 관련하여 고등식물의 발달과 대사과정에서의 중요성이 확인된 것으로 사료된다.

  • Religion is not fixed and permanent and is constantly transforming and changing phenomenon. But in some religions, religious culture happens that emphasize the original and authentic teaching of the founder and removes the other accumulations among the accumulated religious tradition. So some religious communities advocate the original teaching of the founder and insist that they are the orthodox and the others are heresy and make the theory of true transmission etc. Jongtonglon(宗統論) of Daesoonjinrihoe(大巡眞理會) looks similar to the theory of true transmission on the surface. The aim of this paper is the contribution to the understanding of Daesoon thought and the religious culture of Daesoonjinrihoe by studying the characteristics of Jongtonglon. I want to highlight on the characteristics of Jongtonglon by comparing it to Bubmaeklon(法脈論) of Korean Buddhism. Bubmaek(法脈) of Korean Buddhism is well showed in the constitution of Jogaejong(曺溪宗) that represents Korean Buddhism. The constitution says that Jogaejong considers SakyaMuni the main Buddha and Doyi (道義) the founder of Jogaejong and BojoJinul(普照知訥)·TaegoBou (太古普愚) the restorer of tradition and also says that Jogaejong succeedes Cheongheo(淸虛) and Buhyu(浮休). Between SakyaMuni and Doyi, there are several monks of Seocheon(西天)-28Choseol (祖說) and China-6Choseol(祖說). Jinul is highly praised for enhancing the atmosphere of performance of Jogaejong and Bou was regarded as the founder of Jogaejong since late Joseon dynasty. In modern times there were conflicts between Bojojongjoseol(普照宗祖說) and Taegojongjoseol(太古宗祖說), but today's Bubmaek(法脈) of Korean Buddhism was erected after the conflicts was controled. Jongtong of Daesoonjinrihoe was erected by Jo Jengsan(趙鼎山) Doju(道主) who was received Heaven's will through divine revelation. Dojeon(都典) succeeded Jongtong by Doju's will and he didn't say a word when he went to Heaven. So the succession of Jongtong is ended. The first characteristic of Jongtonglon of Daesoonjinrihoe is that the succession of Jongtong was decided by Heaven and has been expected from long ago. The second, Jongtonglon has the sacred characteristic which is not shown in Bubmaeklon. The third, the distinction between Yeonwun(淵源) and Yeonun(緣運) is not appeared in Bubmaeklon. The fourth, Jongtonglon has more anti-syncretic feature than Bubmaeklon. The fifth, Yeonun(緣運) and Bubmaeklon are different in that feature. As Jongtonglon occupies a prominent place in Daesoonjinrihoe, the understanding of it can contribute to grasp the doctrine and culture of Daesoonjinrihoe.
