The communication between the center system and the local controller in the Traffic Signal Controller Specification has been specified by a communication line for the exclusive use and the analog modem serial protocol. Therefore, it can't be adapted in the ITS communication network of the TCP/IP protocol being constructed in the local city. The international and domestic ITS device's communication specification has adapted the DATEX-ASN data exchange technique based on the ethernet communication network. So, this study was performed by the purpose of developing the application communication protocol's standard draft based on the TCP/IP communication protocol for the traffic signal controller, to be able to constitute the traffic signal control system in the ITS communication network. The communication format for 23 items of control, status, and database request etc. which are specified in the standard traffic signal controller was developed by appling the DATEX-ASN data interface procedure and structure which are KS ISO X 14827 Part1, 2, ISO/ DIS 15784 Part-3. To test the developed protocol, the application program for the communication items was developed and according to the test result, the encoding and the decoding transection for all communication items was possible.

Acrylamide is considered as potential carcinogen and genotoxicant. Swedish National Food Administration reported that acrylamide was detected in heat treated starch rich food products. Acrylamide formation during food processing was confirmed by researchers of other countries including UK, Norway, Japan, Switzerland, and United States. It is noticed that the formation of acrylamide in potato products was greater than other food products. It may be due to high concentration of asparagine and glucose in potato products comparing to those of other food products. Interaction between asparagine and glucose during heat treatment resulted in acrylamide formation via Maillard reaction. Analytical method (LC-MS/MS) adopted by FDA was performed to monitor acrylamide concentrations in domestic food products. Acrylamide quantitation in several food categories, such as raw materials, boiled foods, fried foods, hardtacks, breads, breakfast cereals, potato chips, french fries, biscuits, and others, were carried out.

To evaluate the bioequivalence of two venlafaxine formulations, a standard 2-way randomized cross-over study was conducted in twenty-four healthy male Korean volunteers. A single oral dose of 75 mg of test formulation Venfaxine $OR^{(R)}$ (tablet) or reference formulation Efexor $XR^{(R)}$ (capsule) was administered with one-week washout period. Plasma concentrations of venlafaxine were assayed for over a period of 72 hours with a well validated method using liquid chromatography coupled to tandem mass spectrometry (LC-MS-MS). The $mean{\pm}S.D$. of maximum concentration $(C_{max})$ and elimination half-life $(t_{1/2})$ were $64.7{\pm}28.5$ ng/mL, $9.2{\pm}3.0$ h, and $67.2{\pm}30.2$ ng/mL, $9.9{\pm}3.5$ h for test and reference formulations, respectively. Time to reach maximum concentration $(T_{max})$ expressed in median value (range), for the test and the reference, were 10 h (6-14) and 8h (4-12), respectively. Similarly, area under the plasma concentration-time curve, from time zero to last sampling time $(AUC_t)$ and from time zero to time infinity $(AUC_{inf})$, for test and reference formulations were $1185{\pm}755$, $1326{\pm}896$ and $1124{\pm}737$, $1185{\pm}755$ $ng{\cdot}h/mL$, respectively. The parametric 90% confidence intervals on the mean of the differences between the two formulations (test-reference) of the log transformed values of $AUC_t$, and $C_{max}$ were 0.9630 to 1.1383 and 0.8650 to 1.0446, respectively. The overall results indicate that the two formulations are bioequivalent and can be prescribe interchangeably.

Strategies for regional development has been implemented by facilitating the cultural industry since the mid 1990s. The government of Gyeongbuk attempted to establish the cluster of cultural industries and to enhance the capability of cultural industries. However, infrastructure of the industries is still weak. The most cultural industries are small-sized enterprises and are in low value-added production link in the value chain. This research examines the situation of cultural industries and then to recommend the direction of cluster of cultural industries in Gyeongbuk. The cluster of cultural industries in Gyeongbuk needs to be decentralized integration. Cultural industries in Gyeongbuk are found in dispersed regions with own cultural and industrial characteristics. The hub of cluster of cultural industries should be formulated to promote network among cultural industrial complexes in dispersed regions; thus, the hub is able to provide knowledge and information for the cultural industrial firms in Gyeongbuk. The supporting center as the hub of cluster has to input more energy to establish the on-line and off-line network among firms, and between firms and innovation agencies such as universities, cultural industrial organizations, and local governments. The cultural industrial cluster should be linked with IT cluster in Gumi and cluster of Daegu cultural industries to upgrade the value chain of cultural industries.

This article examines magical realism in contemporary european film, which is considered to be one of the most popular styles in the present culture, with regards to Antonio Negri's theory of art. Magical realism is "alternative approach to reality" (Maggie Ann Bowers, Magic(al) Realism) and defined as "a fictional technique that combines fantasy with raw physical reality or social reality in a search for truth beyond that available from the surface of everyday life" (Joan Mellen, Magic Realism). The term of Magic Realism was coined in 1923 by Franz Roh, German art historian, as the concept for the post-expressionist painting in Germany. It has flourished in the Latin-American literature during the 1950s to 1980s and spread worldwide. Since 1980s magical realism is considered to be a universal artistic mode. Since 1990s magical realism is to find in the various novels, and since 2000 one encounters magical realism in the cinema very often. Antonio Negri writes about the relationship between life, imagination, art and the political in his book Art et Multitude. According to Negri, the hard life of people in the present society liberates the imagination and this creates the art as "the excess of the existence". In this process the aesthetic becomes to the political. Negri calls this space of art as "magical time and space". Claire Denis' film Vendredi Soir is analyzed as a contemporary magic realist text, which realizes Negri's concept of art: vendredi soir (friday night) in Vendredi Soir is the magical time, when the impossible becomes the possible, and paris in the public transportation strike is the magical space, where the individuals meet the other in a new situation. The film analysis associates itself with Negri's theory of art: in Vendredi Soir, it is to see, that the excess of the existence liberates imagination and creates the magic reality both in the movements of things and the human relationship. The phenomenon of magical realism in contemporary culture can be understood as the symptom of the emotional and existential pains of contemporary people in the current world. The contemporaneity of the magical realism can be read in the film as "the metaphor for contemporary thought" (Alain Badiou, Cinema). As Antonio Negri writes, art can become "the aesthetic redemption" (Negri, Art et Multitude) for us. At the same time "(t)his is where aesthetics can be transformed into the political." (Lee, "Communism and the Void")

This paper studies the recent surge in the number of faith-based films in Hollywood, with the aim to explore the context and implications of this new trend. By using the theoretical framework of the study of the Tilich and Van der Leeuw, who have explored the relationship between religion, culture and art, this article discusses the meaning of the spiritual theme in the film. A couple of common points can be found among the faith-based films that have been produced since the 2010s. While these films attempt a universal approach to the fundamental theme of spirituality through popular narratives familiar to the audience, they also stress 'historical truthfulness and credibility' by representing the reality, such as a featuring real person or a true story in the film. The main characters are depicted as "victorious losers" that are distinguished from the typical Hollywood superhero and the films repeatedly show the human being constantly 'asking' questions to God. By analyzing these characteristics, the paper demonstrates that recent Hollywood faith-based films have successfully differentiated themselves from existing religious films while symbolizing the universal beliefs and values beyond the religious message so as to attract more audiences to this field. The paper also suggests that despite the advances in modern science and knowledge, the public will always yearn for a spiritual recovery and salvation through the film medium, serving as a potential source that provides an outlet for spiritual experience.

When video composes mise-en-scene during the performance, it reflects the aspect of contemporary image culture, where the individual as creator joins in the image culture through the device of cell phone and computer remediating the former video technology. It also closely related with the contemporary theatre culture in which 1960's and 1970's video art was weaved into the contemporary performance theatre. With these cultural background, theatre practitioners regarded media-friendly mise-en-scene as an alternative facing the cultural landscape the linear representational narrative did not correspond to the present culture. Nonetheless, it can not be ignored that video in the performance theatre is remediating its historical function: to criticize the social reality. to enrich the aesthetic or emotional reality. I focused video in the performance theatre could feature the object with the image by realizing the realtime relay, emphasizing the situation within the frame, and strengthening the reality by alluding the object as a gesutre. So I explored its two historical manuel. First, video recorded the spot, communicated the information, and arose the audience's recognition of the object to its critical function. Second, video in performance theatre could redistribute perceptual way according to the editing method like as close up, slow motion, multiple perspective, montage and collage, and transformation of the image to the aesthetic function. Reminding the historical function of video in contemporary performance theatre, I analyzed two shows, Schaubuhne's Hamlet and Lenea de Sombra's Amarillo which were introduced to Korean audiences during the 2010 Seoul Theatre Olympics. It is known to us that Ostermeir found real social reality as a text and made the play the context. In this, he used video as a vehicle to penetrate the social reality through the hero's perspective. It is also noteworthy that Ostermeir understood Hamlet's dilemma as these days' young generation's propensity. They delayed action while being involved in image culture. Besides his use of video in the piece revitalized the aesthetic function of video by hypermedial perceptual method. Amarillo combined documentary theatre method with installation, physical theatre, and video relay on the spot, and activated aesthetic function with the intermediality, its interacting co-relationship between the media. In this performance theatre, video has recorded and pursued the absent presence of the real people who died or lost in the desert. At the same time it fantasized the emotional aspect of the people at the moment of their death, which would be opaque or non prominent otherwise. As a conclusion, I found the video in contemporary performance theatre visualized the rupture between the media and perform their intermediality. It attempted to disturb the transparent immediacy to invoke the spectator's perception to the theatrical situation, to open its emotional and spiritual aspect, and to remind the realities as with Schaubuhne's Hamlet and Lenea de Sombra's Amarillo.

Following the earthquake in Gyeongju (2016) and Pohang (2017), South Korea is no longer a safe place for earthquakes. Accordingly, the need for shelters suitable for disaster environments is increasing. In this study, a lightweight composite panel was used to produce post-disaster housing for refugees to compensate for the disadvantages of existing evacuation facilities. For this purpose, an evaluation of structural performance and thermal environment for post-disaster housing for refugees composed of lightweight composite panels was performed. To assess the structural performance, a lateral loading test was conducted on a system made of lightweight composite panels. The specimens consisted of two types, which differed according to the bonding method, as a variable. In addition, the seismic and wind loads were calculated in accordance with KBC 2016 and compared with the experimental results. Regarding the energy performance, optimization of south-facing window planning and window-wall ratio and solar heat gain coefficient were analyzed to minimize heating, cooling, and lighting energy. As a result, the specimens composed of lightweight composite panels will perform sufficiently safely for lateral loads and the optimized window planning will lead to a low-energy operation.

Non-small cell lung cancer (NSCLC) has the infamous distinction of being the leading cause of global cancer-related death over the past decade, and novel molecular targets are urgently required to change this status. We previously conducted a microarray analysis to investigate the association of transcription factor activating enhancer-binding protein 2C (TFAP2C) with NSCLC and revealed its oncogenic roles in NSCLC development. In this study, to identify new biomarkers for NSCLC, we focused on several oncogenes from the microarray analysis that are transcriptionally regulated by TFAP2C. Here, the cell division cycle 20 (CDC20) and tribbles pseudokinase 3 (TRIB3) were subsequently found as potential potent oncogenes as they are positively regulated by TFAP2C. The results showed that the mRNA and protein levels of CDC20 and TRIB3 were down-regulated in two NSCLC cell lines (NCI-H292 and NCI-H838), which were treated with TFAP2C siRNA, and that the overexpression of either CDC20 or TRIB3 was responsible for promoting cell viability in both NSCLC cell lines. In addition, apoptotic levels of NCI-H292 and NCI-H838 cells treated with TFAP2C siRNA were found to be suppressed by the overexpression of either CDC20 or TRIB3. Together, these results suggest that CDC20 and TRIB3 are positively related to NSCLC tumorigenesis and that they should be considered as potential prognostic markers for developing an NSCLC therapy.

The number of natural disasters in Korea, such as earthquakes, is increasing. As a result, there is growing need for temporary residences or shelters for disaster conditions. The aim of this study was to produce post-disaster refugees housing differentiated from existing shelters using lightweight composite panels. To accomplish this, the structural performance of lightweight composite panels was validated, and an in-plane shear strength test was conducted according to the ASTM E72 criteria among the performance test methods for panels. As a result of the experiment, the maximum load for each specimen under an in-plane shear load was determined. All the experiments ended with the tear of the panel's skin section. The initial stiffness of the specimens was consistent with that predicted by the calculations. On the other hand, local crushing and tearing, as well as the characteristics of the panel, resulted in a decrease in stiffness and final failure. Specimens with an opening showed a difference in stiffness and strength from the basic experiment. The maximum load and the effective area were found to be proportional. Through this process, the allowable shear stress of the specimens was calculated and the average allowable shear stress was determined. The average ultimate shear stress of the lightweight composite panels was found to be $0.047N/mm^2$, which provides a criterion of judgement that could be used to expect the allowable load of lightweight composite panels.
