  • Oxide semiconductors are attractive materials for thin-film electronics and optoelectronics due to compatibility with synthesis on large-area, glass and flexible substrate. However, development of thin-film electronics has been hampered by the limited number of semiconducting oxides that are p-type. We report on the effect of the oxygen partial pressure ratio in the gas mixture on the electrical and optical properties of spinel Mg:$ZnCo_2O_4$ thin films deposited at room temperature using RF sputtering, that exhibit p-type conduction. The thin-films are deposited at room temperature in a background of oxygen using a polycrystalline Mg:$ZnCo_2O_4$ ablation target. The p-type conduction is confirmed by positive Seebeck coefficient and positive Hall coefficient. The electrical resistivity and carrier concentration in on dependent Mg:$ZnCo_2O_4$ thin films were found to be dependent on the oxygen partial pressure ratio. As a result, it is revealed that the Mg:$ZnCo_2O_4$ thin-films were greatly influenced on the electrical and optical properties by the oxygen partial pressure condition. The visible region of the spectrum of 36~85%, and hole mobility of 1.1~3.7 $cm^2$/Vs, were obtained.

  • In the history, 'father' has been described as a being who not only take care of the family but also represents the family socially and supports them. Like the Western patriarchal tradition prevalent in the 19th century, fathers in Korean society also bear patriarchal paternity based on Korean traditional Confucian culture. In such a unique family culture of Korea, Korean fathers hold the patriarchal male centered idea and regard it as the roles of man and father to be responsible for the family's living and safety and to be more rational than emotional and more blunt than gentle. Social ideology for this image of father is expressed in media, and an example is the patriarchal image of father in TV dramas and movies. In order to analyze the image of Korean fathers described in films, this study selected two films and examined the semiological meanings of fathers' roles expressed in the films using Metz's syntagmatic and paradigmatic analysis method. The films chosen for case study are 'Fly Daddy', 'The Show Must Go On', and 'Speed Scandal'. These films are good examples demonstrating that Korean patriarchal paternity and its background traditional ideology are projected on media.

  • This paper attempts to analyze the narrative strategy of co-produced transnational romance films, (2007) and (2010). These films were produced during the heyday of Korean wave, the phenomenon Korean popular culture enjoys overseas fandom. Coupling Korean male star with Japanese female star, and dramatizing their romance, the industries attempted to attract the nations' cultural consumers. International co-production has been considered as a mode of production strategic enough to penetrate into neighboring nations. One of the major benefits of international co-production is to cope with 'cultural discount' between nations. Since producers and directors from different cultural background can participate in the creative process and share ideas, they can devise quite strategic form and content to please culturally heterogeneous consumers. Korea and Japan have long been in socio-political conflict, which makes it crucial for these films' cultural producers not to stir spectators' nationalism. In other words, these films' cultural producers had to develop a narrative strategy not to analogize nations' political reality. This paper, therefore, aims to analyze the narrative structure of these films, and to specify narrative strategy in detail.

  • BACKGROUND: Plastics that are used in our daily lives largely end up in the environment. In agricultural environments, plastic wastes and microplastics can be found due to the uses and improper management of plastic products (e.g., vinyl greenhouses and mulching vinyl). Microplastics can also interact with contaminants in the agricultural environment. Therefore, this study was set to investigate the sorption characteristics of tetracycline, one of widely used antibiotics, on microplastics. METHODS AND RESULTS: The sorption tests were carried out with the tetracycline solutions (0-30 mg L-1) and microplastic films prepared from low density polyethylene (LDPE) and polyvinyl chloride (PVC). The residual tetracycline concentrations were analyzed and fitted to the Freundlich and Langmuir isotherm models. The tetracycline sorption patterns on LDPE and PVC films were described better with the Freundlich isotherm model than the Langmuir isotherm model. The isotherm model parameters suggested that the maximum sorption amount of tetracyline was greater for PVC, while the sorption affinity was greater for LDPE. CONCLUSION(S): Different types of microplastics can have different sorption characteristics of tetracycline. Therefore, there is a need for continuous research on the interaction of various types and shapes of microplastics and contaminants in the environment.

  • Identification of coating film species from ancient coating materials is needed to maintaine their surfaces without loss of their original beauty for a long time and understand the historical background of manufacturing techniques. A pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) was applied to identify the origine of films in ancient coating materials. The pyrolysis products, which reflect the source from which they originate were detected distinctively at $500^{\circ}C$. This is a rapid technique that does not require large amounts of sample or any sample preparation. Sesquiterpenes are a class of terpenes that consist of three isoprene units were identified as cadienes, selinenes, cubebenes from the raw material of dendropanax morbifera. On the other hand, alkanes(tetra~heptadecanes), alkenes (tri~heptadecenes), allkyphenols, catechols and fatty acids were detected from the raw material of the lacquer film. Based on these results, the origine of historic coatings artifacts was identified using py-GC/MS by comparison with their pyrolysis products.

  • Under the background of globalization, the borderless nature of film and television language makes the exchange of film as the carrier become an important part of cultural exchanges in various countries. Therefore, film co-production between China and the United States, China and Japan, China and South Korea and other countries has become an important part of the current Chinese film industry. Among them, China and South Korea are close neighbors, and the exchanges between the two countries' films are also increasing. Korean movies have recovered since the 1990s, and they prospered at the beginning of the 21st century, and have formed a unique influence in the international community, especially in crime, suspense, love and other types of films. The co-production of Chinese and Korean films began to appear in 2000, and the signing of the "China-Korea Co-production Film Agreement" in 2014 prompted the rapid convergence of Chinese and Korean film co-productions. However, the co-productions of China and South Korea did not achieve good expectations in terms of communication effects and market evaluation. This article will use the "cultural discount" theory in cross-cultural communication to analyze the reasons for the cultural discounts produced by Chinese and Korean co-productions and how to avoid this phenomenon to the maximum extent.

  • Movie has a light, colors, and texture in the space and a design. Movie is a ovation of the 3-dimensional reality with time and space. Just like a movie, a space can also express time, personality of characters and background stories. Symbolization of a space tells philosophy and emotions, making meaning of the space abundant and consistency in entire composition of the space. Expression of beauty through order of space inside proves meaning of space. Think that can do and present to production methodology of space design to universalize ureas through symbolic productions that is based on story.

  • In order to fabricate high sensitive and stable biosensors, we require the material with superior biocompatibility and physical-chemical stability. Many kinds of biomaterials have been evaluated to apply for bioindustry. Recently, carbon based diamond thin films have been focal pointed as bio-applications and their possibility has been evaluated. Diamond thin film has many advantages for electrochemical and biological applications, such as wide potential window (3.0-3.5V), low background current and chemical-physical stability. In this work, we have cultured neuroblastoma cell (SH-SY5Y) on the crystalline diamond films. We use MTT assay to evaluate the characteristic of cell culture on the substrates. As a result, neuroblastoma cell was cultured on the crystalline diamond film as similar as cell culture dish.

  • This study analyzed newspaper reports in the United States and South Korea that focused on Parasite's unprecedented performance at the 2020 Academy Awards. The research focused on the power relationship between 'the established and the outsiders (Elias & Scotson, 1994)' as represented by the Academy Awards and Parasite, respectively. Qualitative content analysis and text analysis were conducted to examine the reporting of American and South Korean newspapers and illuminate three aspects of the power relations between the Academy Awards and Parasite. Three major findings were derived. First, the Academy traditionally has a reputation for marginalizing films with a non-English or Asian background, but recognition of Parasite at the 92nd ceremony changed the Academy's established position of power. Second, historically, the Academy Awards had been characterized by a group charisma that exerts stigmatization (through an English-oriented policy and language stigmatization) and accords North American films priority over non-English movies. Lastly, the reports of newspapers in the two countries are generally similar, but the Korean articles internalized the individual, society, and the state.
