감은사는 문무왕대에 시창하여 신문왕 2년(682)에 완공된 신라중대의 불교사원이다. 본 연구는, 기존의 감은사지 발굴조사 성과를 기초로 하고, 역사학 분야 등에서의 문헌연구 성과를 참고로 하여, 신라감은사건축의 조영계획 양상 및 특질, 그리고 그것과 당시의 정치·사회적, 종교적 환경 간의 관계에 대한 구명을 시도한 것이다. 연구 결과는 다음과 같다. (1) 감은사 중심곽 내 당탑 및 회랑, 중문과 강당 등 모든 건축물은, 기단부를 기준하여, 방(方)216척(尺)(고구려척, 추정단 위치수 353.30mm)의 윤곽에 남거나 부족함 없이 정확하게 들어가는 것으로 확인된다. 이러한 사실은, '만파식적설화'와 유교예악사상과의 관계, '이견대'의 명칭과 『주역』과의 관계, '감은사지출토 태극무늬장대석'과 『주역』과의 관계 등으로부터 확인되는, 동해구 유적(대왕암·이견대·감은사)에 서린 신라중대왕실의 '유교정치이념의 표방' 의지에 비추어 볼 때 매우 유의미한 것으로 판단되며, 감은사가람의 설계초기단계에 있어서, 잠재하는 규모계획의 기준으로부터 이차적 조정으로서, 『주역』 계사상의 '건지책 216'으로부터 수를 취해 가람중심곽규모의 결정기준으로 삼은 결과로 추정된다. 감은사 당탑 등의 배치계획은, 방(方)216척(尺)의 윤곽 내, 가장자리로부터 중심부로, 즉 가람중축선상 중문·강당의 배치 및 금당 남북위치의 결정, (중문·강당·금당 측면에 각각) 남회랑·강당동서편건물·익랑 배치, 동서회랑의 배치, 동서 석탑 중심위치 결정의 순으로 진행되었을 것으로 추찰된다. (2) 감은사건축에 있어서의 유불공존적 양상은, 『금광명경(金光明經)』에 대한 이해를 바탕으로 한 것이며, 왕의 화신인 용이 용혈(龍穴)을 통해 금당기단 내에 들어 선요(旋繞) 즉, 공경·숭봉(崇奉)을 행함으로써 "음양조화시부월서(陰陽調和時不越序) 일월성숙부실상도(日月星宿不失常度) 풍우수시무제재횡(風雨隨時無諸災横)" 등의 무량공덕이 얻어지기를, 그리고 일월에 비유되는 부처의 광명이, 새로이 유교를 정치이념으로 삼아 운영해 나갈 국가, 신라의 사방 천하(천(天)=건(乾), 건지책 216척(尺) 규모의 가람중심곽)에 길이 두루 비춰지기를 염원한 문무왕의 뜻에서 비롯된 것으로 추찰된다. 그리고 그 구상 및 실현에 있어서는 유불습합적 사상 경향을 가졌던, 그리고 문무왕이 유언으로서 국사로 삼기를 당부했고 신문왕 즉위 후 국로로 임명되었던, 경흥(憬興)이 깊이 관여했을 것으로 추측된다.

A modified $\delta$-endotoxin gene of Bacillus thuringiensis ssp. tenebrionis (B.t.t.), encoding a coleoptera-specific toxin, was utilized to transform citrus plants, Citrus reticulata Blanco 'Ponkan' mandarian. By co-culturing the nucelli with Agrobacterium tumefaciens harboring the modified gene in the binary vector pBinAR-Btt, the chimeric toxin gene was transferred into citrus plants. The transgenic plants were selected on modified Murashige and Skoog medium containing kanamycin. Hybridization experiments demonstrated that the transgenic plants contained and expressed the toxin protein gene.

With vigorous development of global network community, smart phones and mobile devices, enterprises can rapidly collect various kinds of data from internal and external environments. How to discover valuable information and transform it into new business opportunities from big data which grow rapidly is an extremely important issue for current enterprises. This study treats Company S as the subject and tries to find the factors of big data application in enterprises by a modified Decision Making Trial and Evaluation Laboratory (DEMATEL) and perceived benefits - perceived barriers relation matrix as reference for big data application and management of managers or marketing personnel in other organizations or related industry.

In this paper, we propose a downlink power control scheme to apply in the unequal error protection multi-code CDMA mobile medicine system. The mobile medicine system contains (i) blood pressure and body temperature measurement value, (ii) ECG medical signals measured by the electrocardiogram device, (iii) mobile patient's history, (iv) G.729 audio signal, MPEG-4 CCD sensor video signal, and JPEG2000 medical image. By the help of the multi-code CDMA spread spectrum communication system with downlink power control scheme and unequal error protection strategy, it is possible to transmit mobile medicine media and meet the quality of service. Numerical analysis and simulation results show that the system is a well transmission platform in mobile medicine.

This paper presents a single-stage ZVT full-bridge AC/DC converter for aerospace applications. The detailed operating principle and design consideration of this soft-switched converter are analyzed and described. The proposed circuit topology and control scheme are proposed to exhibit optimum performances (i.e. high power factor, high efficiency, ring-free and low EMI features). A laboratory prototype, 500W 5V/100A AC/DC converter was implemented. The simulation and experimental waveforms verify the feasibility of the proposed design.

In this research, the simulation method for acoustic sounds by a uniform flow around a two-dimensional circular cylinder by using the finite difference lattice Boltzmann model is explained. To begin with, we examine the boundary condition which determined with the distribution function $f_i^{(0)}$ concerning with density, velocity and internal energy at boundary node. Very small acoustic pressure fluctuation, with same frequency as that of Karman vortex street, is compared with the pressure fluctuation around a circular cylinder. The acoustic sound' propagation velocity shows that acoustic approa ching the upstream, due to the Doppler effect in the uniform flow, slowly propagated. For the do wnstream, on the other hand, it quickly propagates. It is also apparently the size of sound pressure was proportional to the central distance $r^{-1/2}$ of the circular cylinder. The lattice BGK model for compressible fluids is shown to be one of powerful tool for simulation of gas flows.

This study investigates the effects of information and predisposition on individual responses to hypothetical questions. By employing the empirical implications of theoretical models (EITM) framework, I confirm that information and predisposition have positive effects on individual substantive responses to the hypothetical questions about the independence-unification issue in Taiwan. Respondents with higher levels of information and predisposition are more likely to provide substantive responses. More importantly, information and predisposition exert a negative interaction effect on individual responses to hypothetical questions, which implies that when an individual counts more on information to respond to hypothetical questions, her predisposition plays a less important role in her responses and vice versa. Finally, this study suggests that hypothetical questions are effective to probe individual opinion on specific issues under hypothetical conditions.

In this paper, a three-phase AC-DC high step-up converter is developed for application to microscale wind-power generation systems. Such an AC-DC boost converter prossessess the property of the single-switch high step-up DC-DC structure. For power factor correction, the advanced half-stage converter is operated under the discontinuous conduction mode (DCM). Simulatanously, to achieve a high step-up voltage gain, the back half-stage functions in the continuous conduction mode (CCM). A high voltage gain can be obtained by use of an output-capacitor mass and a coupled inductor. Compared to the output voltage, the voltage stress is decreased on the switch. To lessen the conducting losses, a low rated voltage and small conductive resistance MOSFETs are adopted. In addition, the coupled inductor retrieves the leakage-inductor energy. The operation principle and steady-state behavior are analyzed, and a prototype hardware circuit is realized to verify the performance of the proposed converter.

Rapid growth of internet applications has increased the importance of intrusion detection system (IDS) performance. String matching is the most computation-consuming task in IDS. In this paper, a new algorithm for multiple string matching is proposed. This proposed algorithm is based on the canonical Aho-Corasick algorithm and it utilizes a bidirectional and parallel processing structure to accelerate the matching speed. The proposed string matching algorithm was implemented and patched into Snort for experimental evaluation. Comparing with the canonical Aho-Corasick algorithm, the proposed algorithm has gained much improvement on the matching speed, especially in detecting multiple keywords within a long input text string.
