시청자 공적 가치 인식이 공영방송의 필요성과 TV 수신료 지불의사에 미치는 영향

박종원(Jong-won Park),김광호(Kwang-Ho Kim) 한국디지털콘텐츠학회 2016 한국디지털콘텐츠학회논문지 Vol.17 No.3

This paper is designed to study how public values of viewers impact on the necessity of public service broadcasters and the willingness to payment of TV license fee based on the public-opinion survey regarding raising KBS TV license fee which was submitted to the National Assembly in 2013. To investigate this influence, seven main projects presented by KBS are classified into five public values of public (service) broadcasters such as quality, diversity, universality, social value and global value. The seven key performance tasks were presented by KBS. The study results are summarized as follows. Firstly, the survey group who selected the digital welfare enlargement by free terrestrial multi-channel broadcasting among public values recognized as highest the necessity of public service broadcasting as the most highly. Secondly, regarding the question of raising license fee, 72.4 percent of respondents were in favor of 1,000 won and 43.9 percent of respondents were in favor of 1,500 won. The result of this study shows that public service broadcasting has the possibility of securing the legitimacy of license fee policy when public service broadcasters faithfully carry out the five public values as above.

2차원 그래픽을 3차원 그래픽으로 변환하기 위한 삼차원 그래픽 알고리즘들은 복잡하고 다양한 기법의 사용으로 인하여 대규모의 반복 연산이 요구되고, 이로 인하여 실시간 삼차원 그래픽의 처리가 어려운 경우가 많다. 본 논문은 삼차원 그래픽 처리와 관련된 여러 가지 알고리즘 중에서 Phong Shading 알고리즘의 병렬처리 방법과 고속 하드웨어 처리를 위한 삼차원 그래픽 가속기에 관한 것으로, Park's 다중접근 기억장치와 다수의 연산기로 구성된 SIMD처리기를 사용한 삼차원 그래픽 가속기 구조를 제안하고 있으며, 제안된 가속기 구조를 HDL을 사용한 시뮬레이션을 통해 본 논문에서 제안된 삼차원 그래픽 가속기에 의해 복잡한 알고리즘을 갖은 어떠한 삼차원 그래픽 알고리즘도 병렬 처리 알고리즘을 적용하여 SIMD 가속기에 의한 실시간 처리가 가능함을 보였다. There are many algorithms for 2D to 3D graphic conversion technology which have the high complexity and large scale of iterative computation. So in this paper propose parallel algorithm and high speed graphics accelerator architecture using Park's MAMS(Multiple Access Memory System) for Phong Shading, one of many 3D algorithms. The Proposed SIMD processor architecture is simulated by HDL and simulated and got 30 times faster result. It means any kinds of 3D algorithm can make parallel algorithm and accelerated by SIMD processor with Park's MAMS for real time processing.

항해시스템은 통합항해시스템(INS 또는 IBS)을 중심으로 운항과 관련된 시스템과 장비들이 통합되고 있고, 추진시스템은 통합제어감시시스템(ICMS, IPMS, IMCS 등)을 중심으로 추진제어, 전력제어, 기타 제어시스템 등이 통합되고 있다. 본 논문은 선박의 통합화와 관련하여 선박에서 사용되는 다양한 인터페이스를 네트워크 기반으로 통합시켜주며, 네트워크를 통해 전송된 신호를 다양한 인터페이스를 갖는 장비에 제공해 주기 위해 개발된 통합연동시스템에 대한 설계 및 구현결과를 기술하고 있다. Thus, all systems and sensors corresponding to navigation are integrated to an INS (Integrated Navigation System) or an IBS (Integrated Bridge System). Propulsion automation systems, propulsion systems, auxiliary systems, and power management systems are integrated to an ICMS (Integrated Control and Monitoring System), an IPMS (Integrated Platform Management System), and IMCS (Integrated Monitoring and Control System). This paper introduces the results of designing and implementing an Integrated Interface System which ties up diverse system interfaces via network and inversely converts network signals into a proper interface signal type connected to other systems.

This study used a batch DAF (dissolved air flotation) jar tester to evaluate the algae removal efficiency of alum and PAC coagulants during coagulation, flocculation, and flotation. Optimal coagulant dosages were 0.06 ~ 0.15 mL/L (12.0 ~ 26.0 mg Al/L,17%), 0.08 ~ 0.20 mL/L (10.0 ~ 24.0 mg Al/L, 12%), 0.25 ~ 0.30 mL/L (25.0 ~ 30.0 mg Al/L, 10%) for PAC, and 3.0 ~ 5.0 mL/L (81.0 ~ 135.0 mg Al/L, 2.7%) for alum. Turbidity of treated water was 1.0 ~ 2.0 NTU in optimal coagulation, flocculation, and flotation conditions for the four coagulants types. The amount of coagulant injected tended to decrease with increasing Al content in the coagulant, as follows : 17% PAC < 12% PAC < 10% PAC < 2.7% alum. Turbidity removal efficiencies were in the order of 12% PAC (93.6%) > 10% PAC (92.7%) > 17% PAC (91.3%) > 2.7% Alum (88.1%).

A zeolite material with a Si/Al molar ratio of 1.2 was synthesized by changing the NaOH/CFA ratio of coal fly ash (CFA) via a fusion/hydrothermal reaction in the HD thermal power plant. The change in the crystal structure of the zeolite was confirmed using XRD and SEM, and the ammonia adsorption capacities of the synthesized zeolitic materials and a commercial zeolite (Na-A zeolite) were analyzed via an ammonia temperature-programmed desorption (NH₃-TPD) process. The SEM and XRD results revealed out the zeolitic materials from the coal fly ash maintained a hexagonal Linde-type crystal structure similar to that of Na-A zeolite, but the crystallinity of the synthesized zeolitic material was reduced due to impurities. The NH₃ adsorption capacity, determined from the NH₃-TPD analysis of was 1.122 mmol/g of the synthesized zeolitic material, which was lower than the NH₃ adsorption capacity of the Na-A zeolite.

The one and two pair of oxide modules for high temperature thermoelectric power generation were fabricated with $Ca_{2.7}Bi_{0.3}Co_4O_9$(p-type) and $Ca_{0.96}Bi_{0.04}Mn_{0.96}Nb_{0.04}O_3$(n-type) on $Al_2O_3$ substrate. For the optimizing of the design process, contact resistance was derived from the results of the one pair modules, and then the resistance of two pair modules were calculated to use the derived data. Those values were compared with the measured values for the optimizing of this design process. The resistance of calculated and measured two pairs modules was 0.956 $\Omega$ and 1.110 Q $\Omega$ $T_h$=833 K, respectively, the difference of resistance was about 0.15 $\Omega$. From the result, proposed design process is effective for high temperature thermoelectric oxide modules fabrication. 고온 발전용 열전모듈을 p-type으로는 $Ca_{2.7}Bi_{0.3}Co_4O_9$, n-type으로는 $Ca_{0.96}Bi_{0.04}Mn_{0.96}Nb_{0.04}O_3$을 선택하고 알루미나 기판 위에 1쌍과 2쌍을 제조하였다. 산화물 열전 모듈의 최적화 설계를 위해 먼저 1쌍의 열전모듈의 실험 결과로부터 전극의 접촉저항을 산출하여 2쌍 모듈에 적용함으로써 저항과 출력 특성을 예측하였다. 예측된 2쌍 모듈의 계산 값과 제조된 2쌍 모듈의 실측 값을 비교함으로써 모듈 설계를 위한 접근방법을 검토하였다. 2쌍 모듈의 계산된 저항과 측정된 저항은 각각 $T_h$=833 K에서 0.954 $\Omega$과 1.105 $\Omega$으로 약 0.15 $\Omega$ 정도의 차이로 근접한 결과를 얻었으며, 제시된 방법으로 고온산화물 열전 모듈 제작에 유효하다고 판단된다.
