Recently, the emotional design has become one of the central issues. The interest to Calligraphy also has increased. This study is to examine the effect of calligraphic TV title to viewers through questionnaires. As a result of the questionnaire analysis, calligraphic title makes a favorable impression on viewers. On the other hand, viewers have an antipathy to a drama program with a calligraphic title. The appropriate use of calligraphic title is requested. The viewers prefer that CM Super TV drama title is located to the right side in TV screen. They also prefer the animated moving title to colored background title. This study contributes to the further research about the correlation between TV commercial zap-rate and calligraphic title.

This research examines the legal liability of place-shifting of TV contents by the use of the Slingbox. The place-shifting of TV contents is fair use because it is a non-commercial private use based on the relevant case law regarding time-shifting and device-shifting such as Sony, RIAA and Napster. But the sharing of place-shifting function is likely to be liable for copyright infringement. And place-shifting may not be fair use based on the cases which denied fair use of time-shifting and space-shifting because the consumers' convenience for the use of the copyrighted work is against the purpose of legislation of copyright law. Place-shifting is unlikely to have a significant effect on the potential market for TV contents because it presents lucrative new platforms to disseminate TV contents to computers and mobile devices. However it is likely to have negative effect because various devices can be the follow-up marketplaces of the copyright holders of TV contents. This study proposes the "innovative medium defense," a new doctrine to analyze liability of innovative media.

An efficient method is developed for mold thermal cycle analysis in repeated forming process, which is well suited to the analysis in TV glass production. plunger, which is a mold to press-form the glass, undergoes temperature fluctuation during a cycle due to the repeated contact and separation from the glass, which attains a cyclic steady state in the end. If analyzed straightforwardly of this problem, it leads to more than 80 cycles to get reasonable solution, and it is yet hard to setup stopping creteria due to extremely slow convergence. An exponential fitting method is proposed to solve the problem, where an exponential function is found to best approximate temperature values of 3 consecutive cycles, and new cycle is restarted with the function value at infinite time. From numerical implementation, it is found that the method reduces the number of cycles dramatically to only $6{\sim}15$ cycles to reach accurate solution within $1^{\circ}$ error. A system for the analysis is contructed, in which the thermal analysis is performed by commercial software ANSYS, and the fitting of the result is done by IMSL library.

The commercial rearing of polyphagous Indian tasar silkworm, Antheraea mylitta Drury being practiced on naturally grown primary food plants like Terminalia arjuna, (Arjun) Terminalia tomentosa (Asan), and Shorea robusta (Sal) available in the tropical forests of central India, at times, is seriously affected by the disease- Pebrine, caused by Nosema sp., a microsporidian pathogen. The present investigation on comparative larval, silk gland weight and also cocoon parameters in Pebrine-free and Pebrine-infected ecorace of tasar silkworm Antheraea mylitta Drury (Daba TV), illustrates the tasar silkworm larvae infected with pebrine disease causing heavy losses to the economy of the silk industry.

최근 주요국에서 주파수 자원 개방의 일환으로 TV White Space(TVWS) 관련 정책이 추진되고 있으며, Super-WiFi 및 WRAN을 통한 활용 방안이 중점적으로 논의되고 있다. 이는 이동통신 서비스의 주파수 부족 문제 해소 차원 외에도 비면허 및 저대역 주파수를 사용하는 특성으로 인해 신규 서비스의 등장과 다양한 산업이 개발되고 육성되는 기반이 될 수 있다는 점에서 비(非) 통신계 사업자에게는 큰 기회가 되고 있다. 이에 DB 기반의 TVWS 상용 및 시험 서비스가 가시화됨에 따라 주요국에서 등장하는 TVWS 서비스 현황을 살펴보고, TVWS 서비스의 생태계 분석을 통해 향후 국내 시장환경에 적합한 White Space 서비스 도입 방안제시와 함께 DB 운영 및 이용자 측면에서 바람직한 상용화 정책 방향을 모색하고자 하였다.

The alkali volatilization of TV screen glass melts with various $K_2$O/R$_2$O mole fraction was investigated by dependence of weight loss on time. The melt conductivity was also determined to evaluate relative alkali diffusion in melts. Based on the results of time dependence and compositional dependence of volatilization combining the results of conductivity, the rate determining process of the volatilization was suggested. From the viewpoint of the production and the application of TV glass it was also discussed a correlation between the dependence of properties on $K_2$O/R$_2$O and the present commercial composition.

With the question, "What would be the difference between TV drama image production techniques under the changing circumstances of domestic broadcasting faced with multi-media, multi-channel age after 1980' s press unification and establishment of two times commercial TV stations?" This study analysed image production techniques of three periods of TV drama development, 'TV drama maturity period(1981-1990)', 'TV drama transition period(1991-2000)', 'TV drama take-off period(2001-)'. For the image analysis within the genre of home drama, 3 dramas for each period were selected and analysed cameraworks, shot size, shot duration with the broadcasting station's DVD, homepage and manuscript. The result of this analysis revealed that the change of shot size was slight but the change of cameraworks was great, the usage of zoom and tilt diminished but the usage of dolly and track increased. and the average shot duration drastically diminished during the take-off period. These results show us that broadcasting production equipments developed during the periods, and broadcasting stations poured all-out efforts for the higher viewing rates and international competitiveness.

With the start of digital broadcasting, TV screen, there is provided a new broadcast service is called EPG (Electronic Program Guide) that can be retrieved directly to a channel or program. However, a study considering the EPG of the user interface on the viewer position is so far insufficient. TV is because everyone watching the media, rather than a specific layer is necessary in order to find easy, intuitive user interface for the program to the viewer. That is, it is possible to quickly find the program to select the attributes that the TV viewer can be easily understood by using the EPG. To this end, this paper first genres which are representative of the properties that distinguish a TV program, time, rating, etc. were systematically classified. So viewers the values of the properties but to specify organized by the EPG, the order of attributes that specify the value we design a user interface that can be selected as having easy. And compare the superiority of the function evaluation of the two through the EPG in the EPG Usability Test proposed by the EPG with the existing commercial paper.

This work proposes suitable network configurations for single frequency networks (SFNs) with ATSC 1.0 based on network coverage calculations and the laboratory multipath handling performance of commercial receivers. SFNs are widely used for delivering terrestrial digital television services because of their efficient use of the spectrum. In Mexico the analogue television transmissions switch-off occurred on 31 December 2016. Thus it is expected the adopted ATSC 1.0 system will be in force for the next several years despite the recent standardization of the ATSC 3.0 system. As ATSC 1.0 uses 8-VSB modulation the multipath handling capability of receivers is critical for the design of SFNs. The presented network planning results help develop technical normativity for implementing SFNs in Mexico and other countries that use ATSC 1.0. SFNs with transmitter separation up to 130 km are fully covered for outdoor reception mainly due to the directivity of the receiving antenna. Moreover for indoor reception at least 70% of an SFN coverage area can be achieved with a transmitter separation of up to 60 km depending on the radiated power and the transmitter antenna height.
