The building integrated photovoltaic system (BIPV) attracts attention with regard to the future of the photovoltaic (PV) industry. It is because one of the promising national and civilian projects in the country. Since land area is limited, there is considerable interest in BIPV systems with a variety of angles and shapes of PV panels. It is therefore expected to be one of the major fields for the PV industry in the future. Since the irradiation is different from each installation angle, the output can be predicted by the angles. This is critical for a PV system to be operated at maximum power and use an efficient design. The development characteristics of tilted angles based on data results obtained via long-term monitoring need to be analyzed. The ratio of the theoretically available and actual outputs is compared with the installation angles of each PV module to provide a suitable PV system for the user.

Print gloss is an important attribute of the final printed product. While past work has looked at the influence of key aspects of the coating structure on print gloss, a systematic study has not been reported. The coating roughness, porosity, and pore size are changed by using various combinations of coating materials and by calendering against rough plastic sheets. The print gloss is measured every tenths of a second right after printing, a few minutes after printing, and a few days afterwards. Roughness and porosity affect the print gloss for the first two seconds: this result shows that they influence the ink-film splitting event. Once ink film starts to level, roughness and pore size influences the level of print gloss within the first ten seconds after printing. Porosity modifies the evolution of print gloss for the next few minutes. The decrease in gloss at long times is found to correlate to surface roughness.

This study was carried out to investigate the characterization of cadmium adsorption by cellulose hydrogel and aerogel. Hydrogel and aerogel were made from ashless pulp dissolved in alkali hydroxide-urea aqueous solution and manufactured in film and bead types. After regeneration of cellulose, hydrogel went through the process of substitution of organic solvent and freeze-dry in order to make aerogel. SEM was used to analyze the microstructure of hydrogel and aerogel. Experiment was conducted in various concentrations and pH conditions to find out the characteristic of cadmium adsorption. After that, EDS was used to identify existence and distribution of cadmium in hydrogel and aerogel. The result from comparisons of cadmium adsorption shows that bead type aerogel has the maximum cadmium adsorption and film type hydrogel has the minimum cadmium adsorption.

The aim of this study is to examine agglomeration patterns of advertising industries and spatial networks of advertisement production in Korea. The focus of analysis is the agglomeration pattern of advertising industries within Seoul because these are agglomerated in Seoul like other business services. Analysis methods are local Moran's I index and location quotient with the regional percentages of each sector's number of employees. Clusters in Gangnam Area are related to start-up advertising firms and global agencies entering domestic advertising markets. Network analysis is used to investigate the spatial networks of TV advertisement production between advertising agencies(AA) and film productions(FP). After transformation of AA-FP network matrix to regional matrix centrality index and brokerage scores are calculated. This analysis shows individual region's different role and position in the AA-FP network. Many agencies in or out of Gangnam Area outsource most advertisement makings to film productions in Gangnam Area. Advertising industry dusters in Gangnam Area is important as of the destination of advertisement production networks and the circulation of those networks.

Demand for pressure sensors is increasing in various fields such as machinery, healthcare and medical care. A recent study is being conducted to create sensors that are more sensitive and have longer linear sections based on measurement principles. In this paper, a film-type sensor with a membrane structure was developed to measure the pressure distributed in the axial direction of a hot roll laminator. Performance of sensors was evaluated by resistance and durability according to membrane diameter. The resistance of the membrane sensor varies according to the contact state and contact area of the electrode. Therefore, the membrane diameter selection is important. Experiments showed the most pronounced variation in resistance under pressure at 8 mm in diameter of membrane. Reliability evaluation of sensors was carried out at room temperature and high temperature. The pressure on the sensor was pressurized 1000 times to measure the initial resistance and the resistance after the evaluation to analyze the change. Sensors showed stable results with low resistance changes of 5.15% and 6.27%, respectively. A large area sensor manufactured using the developed sensor also showed reliable results.

Acting is an act of expressing personality, image, sound, tempo, and movement flexibility in order to effectively express fictional characters in the play. It is said to refer to the action or mood of the person performing the character. In addition, all these acts are important elements of the media that the director wants to convey the subject of the work to the audience. In particular, the actor relies on the ambience, image and passionate role of winning and losing in theatrical film. In addition, more than 60% of the afterimages or remaining images in the film are images of the actor's acting or movement, and the trend of the actor. This study is not about acting divided by Conti, who is under the control of directors and directors.

Gameplay exists not only in game activities, but also in other art forms. An animated film with strong gameplay whose gameplay narrative follows the presupposition principle, achieved through unimaginable sound effects, exaggerated visual styling, hypothetical time and space concepts, fictional storylines and character performances. The strength or the presence or absence of gameplay in animated films is reflected in the grasp and use of these gameplay elements in the process of animated film narratives. The gameplay narrative of animated films fully utilizes the characteristics of gameplay thinking. In the process of scriptwriting and narrative, it combines entertainment, action, adventure, competition and other elements to fully reflect the characteristics of "gameplay". Gameplay narratives often use the strategies of reverse setting, repetition and interaction, and rules and challenges setting, which not only enhances the fun of animated film narratives, but also attracts the attention of the audience, which then can enhance the audience's viewing experience.

Zhang yimou's film "the shadow" adopts a lot of modern literary symbolic content in the story structure. The novel has been greatly modified, abandoning the setting of the original work and making up the historical background of the story, thus completing the discourse practice of aerial literature rather than historical literature. The film expresses the historical story poetically and even writes the personal mind. In this way, the audience's sense of substitution is increased, and a large number of traditional Chinese cultural symbols are adopted visually. In terms of clothing, the most traditional is sought, which advocates loyalty to history, and adds cultural connotation and depth. The audience can feel the bold and unfettered artistic creation spirit of the main creator, as well as the novel and unique visual expression style, which makes his works have both traditional visual perception and modern story content. The combination of traditional vision and modern drama forms a new visual and cultural experience.
