Middle aged women these days not only consider themselves as younger than actual, maintain figures and looks of younger women, but also show a big interest to fashion goods as younger generations. The TV media has a big influence on this trend. This study is conducted to figure out how the TV media involvement of middle aged women affects their difference age, youth-pursuing clothing behavior and fashion leadership. After the survey, a total of 326 questionnaires completed by women of their 40s and 50s were used to this analysis. The results are as follows, 1. The highest cognitive age of middle aged women was the look age, and the lowest was the feel age in the 40s, and the interest age in the 50s. And it was shown that the difference age were 7.05 years for the 40s and 9.10 years for the 50s. 2. The TV media involvement had a significant influence on the difference age as its antecedent. And the TV media involvement affected directly the youth-pursuing clothing behavior and fashion leadership. The higher the TV media involvement was, the higher difference age and fashion leadership were shown. 3. The difference age was shown as mediating the TV media involvement and the youth-pursuing clothing behavior, and the TV media involvement and fashion leadership only partially. 4. The youth-pursuing clothing behaviors were influenced by TV media involvement and difference age. Conclusionally, this study revealed that the TV media had a great influence on middle-aged women's clothing behavior, supporting the cultivation theory of TV media.

OFDM Modulation is used for multimedia transmission At Urban Train. Recently the application field about data transmission is expanding the image as well. The case which the number of OFDM carrier is big is advantageous because multipass fading is big 18GHz wireless frequency. Existing WLAN which an ethernet transmission is possible is not suitable to a great distance transmission because number of carrier is 64. In this paper, we developed OFDM modem suitable to transmit broadband data at high speed train. A doppler compensation block added to offset the doppler effect. Therefore, the effectiveness is expected to be very big in field of urban train.

In general, there are many sensors for fuel injection control such as an air flow sensor, an air intake temperature sensor, a cooling water temperature sensor, a throttle position sensor, and a motor position sensor. In this paper, we proposed a method for controlling the amount of fuel consumption in cars using fuzzy control technique by temperature change of an air intake temperature sensor and air-fuel ratio, the ratio of air and fuel mixture. In the proposed method, the amount of fuel injection is controlled by fuzzy membership functions and fuzzy inference rules established for air-fuel ratio, air intake temperature, and final fuel compensation, after computing air-fuel values using each amount of air intake and each amount of fuel injection. We verified that the proposed method is more efficient than conventional methods in fuel injection control from the results of the simulation program.

In mobile broadcasting networks, handover is an important issue to support seamless mobility. DVB-H(Digital Video Broadcasting for Handheld) standard was developed to enhance mobile features for DVB-T(Digital Video Broadcasting -Terrestrial) standard. This paper proposes new approaches for improving handover performance in the DVB-H networks. The proposed handover schemes are targeted to two different DVB-H receivers: One is for the receivers equipped with GPS devices. The other is for ones without GPS support. The first handover approach modifies the cell description table (CDT) proposed in the literature [1]. The second proposes a novel estimation technique of predefined handover region based on a new handover map table (HMT). This new handover approach estimates a predefined handover region with the measured RSSI(Received Signal Strength Indication) signal patterns. Using proposed handover algorithm, we can reduce time and power consumption. Through the computer simulations, we evaluate the performance of handover algorithm.

Korea and Japan share the same view of a single nation state, but there was a difference in the government's COVID-19 emergency relief fund for foreigners. To this end, I analyzed the comments of Korean and Japanese users in YouTube videos related to COVID-19 disaster support funds for foreigners. As a result of the study, As a result, there are many opinions that Korea and Japan are generally sensitive to foreigners' tax payments, and that immigrants can receive national benefits and support like indigenous people if they fulfill their obligations. Next, it can be seen that Korea and Japan recognize each other in common. The difference is that Japan is sensitive to the same nationality, whereas Korea is more focused on tax and money than nationality.

Recently, broadcasting technologies have evolved as high-quality AV services such as domestic terrestrial UHD(Ultra-High Definition) broadcasting have been increasing, and broadcasting standards have been newly defined. Also, as network technology develops, contents are consumed not only in the country but also the world. Accordingly, content insertion technology, which is a method of providing suitable contents in accordance with the national and local environments, will be needed. This paper proposes a content insertion service system model and synchronization scheme using ATSC(Advanced Television Systems Committee) 3.0 Event Signaling standard under heterogeneous network environment of broadcasting network and internet network based on transmission standard DASH(Dynamic Adaptive Streaming over HTTP)/ROUTE(Real time Object delivery Over Unidirectional Transport) and MMT(MPEG Media Transport) of terrestrial UHD broadcasting. It also verifies that the service operates in an environment that meets the broadcast standard.

With the development and popularization of drone manufacturing technology, the drone market, which was mainly focused on industry, agriculture, and military, is also showing great growth in individual and commercial markets. Among them, DJI has a high share in the personal and commercial drone market, and accordingly, forensic analysis of DJI drones is drawing attention. In particular, when stealing and analyzing drones used in criminal acts, a technology to interpret flight logs recording drone flight paths and hardware information is needed, which inevitably applies drone models due to differences in decryption methods. Therefore, when an unidentified drone is acquired from the perspective of a digital forensic investigator, a clear classification of a drone model to which analysis can be applied is required. This paper proposes a method of extracting and analyzing artifacts of DJI drones through forensics, and analyzes media data analysis and flight log analysis results and decryption methods for three drone models with different release years of DJI. Finally, drones in the DJI product line are classified according to whether the commercialized DJI drone flight log is decrypted.

The purpose of this study is to examine the progress of negotiations between the two countries regarding the implementation of AFKN's satellite broadcasting on October 4, 1983, as well as the opposition of domestic public opinion, which emerged as an important variable in the negotiation process. Through this, it was intended to lay the foundation for the historical facts necessary to interpret the negotiation process between the two countries over the implementation of AFKN's satellite broadcasting in the context of world history of cultural globalization. As a research method, the historical literature research method was used, focusing on archive documents stored in diplomatic archives. The study revealed that public opinion's movement toward cultural imperialism under domestic political conditions, which had authoritarian control over the media, served as an accidental factor to help carry out the regime's interests of regime protection. Through these findings, this paper interpreted that AFKN-TV's satellite broadcasting, which was implemented under the U.S. Department of Defense plan without the prior consent of the Korean government, clearly shows that Korea has been "semi-forced" into the U.S.-led cultural globalization order.

This study aims to analysis the types of features of confucian values of China normal university students. To achieve this purpose, Q methodology is applied. This study was conducted at Sichuan Normal University in China. Total 42 students and 47 statements collected through literature research. The implementation were formed in four types, statism, traditionalism, nominalism, and naturalism. Through this study, from the perspective of international relations, family relations, and friendship, all four type of features were presented intellectualized intelligentiae. The common feature of the four types is gender role, and the cognition of gender role is changing, and women will becoming an independent individual. Although confucian values had made great contribution for the development of Chinese traditional culture, it is an undeniable fact that some ideas not according with the modern social demand for development are hidden in the back.And we should look at and appreciate confucian values from a comprehensive and dialectic view.
