The importance of international co-production that enables content production, diversification of overseas markets, and diversification has been highlighted as demand for content has soared due to intensifying competition between media outlets, while contents provision has become easier due to changes in media environment such as convergence of broadcasting and communication and the spread of mobile Internet. In particular, the boom in Korean dramas, called the Korean Wave in China, opened up a new market after "My Love from the Star" in 2014, and in 2016, Netflix's entry into Korea served as an opportunity for local broadcasters and producers to seek international co-production. In addition, "Good Doctor" which was aired on American Broadcasting Co. (ABC) in 2017, has topped the same time slot for the first time in 29 years, and is set to air season 4 this fall. Accordingly, overseas broadcasters and production companies wanted to collaborate with domestic broadcasters and producers, and since 2011, they have conducted a total of 12 co-produced dramas until 2019. Unfortunately, however, there are few studies related to international co-production dramas in the domestic industry and academia. In this paper, we present to help Korea, which used to be a powerhouse in complete export-type content, move toward becoming a powerhouse in international co-produced dramas. In addition, it is meaningful that the research focused on the current status and achievements of international co-production dramas, which have not been studied much, and the diversity of international co-production dramas in the future through the analysis of the form and structure of international co-production.

A significant proportion of the African continent is conducive for animal agricultural production, due to its historical experience and available resources to accommodate and nurture various indigenous and exotic animal species and breeds. With food security being a global challenge, animal products can play an important role as nutrient dense food sources in human diets, particularly in Africa. However, this does not seem to reach its full potential in practice, due to numerous reasons that have not been adequately addressed. Animal welfare reservations can be highlighted as one of the major contributing factors to the curbed progress. The consequences have been scientifically proven to affect product quality and market access. However, in the African community, the concept of animal welfare has not been fully embraced. While there are international animal welfare standards in the developed world, there are inherent factors that hinder adoption of such initiatives in most developing regions, particularly among communal farmers. These include cultural norms and practices, social ranking, socio-economic status, available resources, information dissemination and monitoring tools. Therefore, there is need to harmonize what is internationally required and what is feasible to accommodate global variability. The protocols followed to ensure and evaluate farm animal welfare require regular investigation, innovation and a sustainable approach to enhance animal productivity, efficiency and product quality. Additionally, investing in animal wellbeing and health, as well as empowering communities with significant knowledge, has a potential to improve African livelihoods and contribute to food security. This review seeks to highlight the concept of animal welfare in relation to livestock and food production in African conditions.

As the market for Internet of Things (IoT) service grows, the security issue of the data from IoT devices becomes more important. In this paper, we implemented a cryptographic library for confidentiality of sensor data from Android Things based IoT services. The library made use of the SEED algorithm for encryption/decryption of data and we verified the library by implementing a service environment. With the library, the data is securely encrypted and stored in the database and the service environment is able to represent the current sensing status with the decrypted sensor data. The contribution of this work is in verifying the usability of SEED based encryption library by implementation in IoT sensor based service environment.

Virtual Reality (VR) has lately gained significant attention primarily driven by the recent market availability of consumer devices, such as mobile phone-based Head Mounted Displays (HMDs). Apart from classic gaming use cases, the delivery of $360^{\circ}$ video is considered as another major application and is expected to be ubiquitous in the near future. However, the delivery and decoding of high-resolution $360^{\circ}$ videos in desirable quality is a challenging task due to network limitations and constraints on available end device decoding and processing. In this paper, we focus on aspects of $360^{\circ}$ video streaming and provide an overview and discussion of possible solutions as well as considerations for future VR video streaming applications. This paper mainly focuses on the status of the standardization activities, Omnidirectional MediA Format (OMAF), to support interoperable $360^{\circ}$ video streaming services. More concretely, MPEG's ongoing work for OMA aims at harmonization of VR video platforms and applications. The paper also discusses the integration in MPEG Dynamic Adaptive Streaming over HTTP (MPEG-DASH), which is considered as $360^{\circ}$ video streaming services with OMAF content. In context of the general OMAF service architecture.

This paper examines port redevelopment and urban regeneration projects of foreign advanced countries and investigates policy implications to apply to Korean port cities. Busan and Incheon have started to redevelop old port facilities located near old city centers and they have been faced several problems. Significant findings are found from the experiences of Inner Harbor in Baltimore, Darling Harbor in Sydney, Hafencity in Hamburg, Eastern Dockland in Amsterdam and Minatomirai 21 in Yokohama etc. At first, port and city have to be integrated to an unique regeneration project in order to solve the spatially disconnected problems originated from separate development in the initial stage. Preservation of historical regional assets is highly recommended to characterize its own value which is emphasized in the age of post modernism. Accurate and consistent design guidelines of port cities are stressed to build high standard cities. In the perspective of investigating a new business model, anchor facilities and place marketing strategies are introduced to induce more people to the place specially in the beginning stage. In addition, creative financing methods and competent implementing bodies are emphasized to running the projects stably regardless of real estate market status.

From the era of feature phone to the current smart phone which bloomed Social Network Games(SNGs), mobile games have held the top position as killer contents of mobile market. Mobile game has many constraints such as specification of device, network status, and external environment. Based on common perspective of game research, these factors have negative influences on flow of user. Even with these opinions, most mobile gamers have felt satisfaction. To explain this phenomenon, our research focuses on the constraints. Referring to theoretical concepts, we attempt to clarify the relationship between game features and flow through survey methodology. Our finding shows that the constraints have a positive effect on flow even though it disaccords with previous studies. Therefore, we argue that users of mobile game have sense of satisfaction not a cognitive overload as discomforts.

It is important for the strategy of service to provide the weather information in the environment that the smart clothing has been changed focusing on the consumer center. Recently, the various applications of smart clothing concept have been presented by researchers and developers. Among them, the smart clothing based on the sensors is most likely to gain the highest demand rate in the market. In this paper, we proposed the life weather index monitoring system using the wearable based smart cap. By wearing the proposed smart cap, the weather status is gathered and its signals are transmitted to the connected UMPC. It can be easily monitored in real time. To provide the life weather index according to the sensors, the weather index was analyzed in terms of 6 factors, such as, the heat index, the food poisoning index, the discomfort index, the ultraviolet index, the water pipe freeze possibility index, and the windchill temperature index. Ultimately, this paper suggests empirical application to verify the adequacy and the validity with the life weather index monitoring system. Accordingly, the satisfaction and the quality of services will be improved the smart clothing.
