With the deepening cooperation between China and South Korea in the field of film, the ways of cooperation between China and South Korea are becoming more and more diversified. "One text, two productions" film cooperation mode refers to the filmmakers of two countries sharing script resources, using the same script to create films separately. South Korean Extreme Job(극한직업) and Chinese Lobster cop(龙虾刑警) are the products of this cooperation model. The scripts of the two films originated from the China and South Korea story joint development plan(중한시나리오공통개발프로젝트) in 2015. After winning the award, the script were filmed by Korean and Chinese filmmakers. Filmmakers in two countries adapted the script to different degrees according to their respective cultural backgrounds and aesthetic characteristics. The film cooperation mode of "One text, two productions" promotes the development of transnational cooperation and opens up a new way of film cooperation.

Previous studies have investigated a between-category relationship of multiple acoustic cues for a laryngeal contrast by examining the distributions of VOT, f0 and H1-H2. The current study examined within-category correlations between cues comprising stops by Korean- and English-speaking adults and children to understand how children master the internal structure of stop phonation types in two languages. Word-initial stops were collected from about 70 children and 15 adults speaking English and Korean, and were analyzed in terms of VOT, f0 and H1-H2 to compute correlation coefficients. Findings in adults' productions included a gender-differentiated cue-correlation pattern associated with H1-H2 in Korean tense stops and a trading relationship between f0 and VOT in Korean lax and aspirated stops and English voiced and voiceless stops. Children did not necessarily have adult-like cue-correlation patterns even in early-acquired categories, suggesting that the mastery of intra-category structure of phonation type might occur later than inter-category structure.

The purpose of this study is find the relation between students' concept and types of proof construction. For this, four undergraduate students majored in mathematics education were evaluated to examine how they understand mathematical concepts and apply their concepts to their proving. Investigating students' proof with their concepts would be important to find implications for how students have to understand formal concepts to success in proving. The participants' proof productions were classified into syntactic proof productions and semantic proof productions. By comparing syntactic provers and semantic provers, we could reveal that the approaches to find idea for proof were different for two groups. The syntactic provers utilized procedural knowledges which had been accumulated from their proving experiences. On the other hand, the semantic provers made use of their concept images to understand why the given statements were true and to get a key idea for proof during this process. The distinctions of approaches to proving between two groups were related to students' concepts. Both two types of provers had accurate formal concepts. But the syntactic provers also knew how they applied formal concepts in proving. On the other hand, the semantic provers had concept images which contained the details and meaning of formal concept well. So they were able to use their concept images to get an idea of proving and to express their idea in formal mathematical language. This study leads us to two suggestions for helping students prove. First, undergraduate students should develop their concept images which contain meanings and details of formal concepts in order to produce a meaningful proof. Second, formal concepts with procedural knowledge could be essential to develop informal reasoning into mathematical proof.

The purpose of this study was to investigate differences in regions and social environmental factors for centenarians between two countries. The sample sizes for this paper were a total number of centenarians in the two countries. Centenarians from different regions were examined in conjunction with the social environmental factors of the longevity approach. Statistical analysis was done using the Pearson's coefficient of correlation and regression equations. It became evident that centenarians among two countries lived in regions with lower income levels, lower tobacco consumption, lower levels of air pollution, onion and barley productions, fewer motor vehicles, a lower divorce rate, lower unemployment, soybean and garlic productions, and less water pollution. The finding imply that centenarians among two countries lead to a life of longevity is the result not only social environmental factors reactions that have fresh air, clean water and health food but also of health behaviors that have bacco consumption and divorce rate. Also, these support future studies of improvement of social environmental pollution, agricultural products of health food, and health behaviors of nonsmoking for life of longevity.

The MERRA reanalysis data provided online by NASA was applied to predict the annual energy productions of two largest wind farms in Korea. The two wind farms, Gangwon wind farm and Yeongyang wind farm, are located on complex terrain. For the prediction, a commercial CFD program, WindSim, was used. The annual energy productions of the two wind farms were obtained for three separate years of MERRA data from June 2007 to May 2012, and the results were compared with the measured values listed in the CDM reports of the two wind farms. As the result, the prediction errors of six comparisons were within 9 percent when the availabilities of the wind farms were assumed to be 100 percent. Although further investigations are necessary, the MERRA reanalysis data seem useful tentatively to predict adjacent wind resources when measurement data are not available.

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.

The Two Nations One Mind film contest was launched by the collaboration between Pukyong National University (PKNU) in Busan, The Republic of Korea (South Korea) and the University of the Thai Chamber of Commerce (UTCC) in Bangkok, Thailand. The project was funded mainly by the Ministry of Foreign Affairs, South Korea. The intention of the project was to increase the recognition of Korea in Thailand through co-production filmmaking between university students from the two countries. This paper aims to look at the feedback from the project participants from both nations as to how international co-productions resulted in cultural exchange and international youth cooperation. The paper also examines the films produced from the project, Blossom, Different (Yet) the Same, Two Taste, Two Nations and When I Was There, for how they reflect the elements of transnational cinema. The comments from the films' audience were also taken as part of the data.

Speaker identification system basically functions by comparing spectral energy of an individual production model with that of an input signal. This study aimed to develop a new speaker identification system from two parameters from the spectral energy of numeric sounds: difference sum and correlation coefficient. A narrow-band spectrogram yielded more stable spectral energy across time than a wide-band one. In this paper, we collected empirical data from four male speakers and tested the speaker identification system. The subjects produced 18 combinations of three-digit numeric. sounds !en times each. Five productions of each three-digit number were statistically averaged to make a model for each speaker. Then, the remaining five productions were tested on the system. Results showed that when the threshold for the absolute difference sum was set to 1200, all the speakers could not pass the system while everybody could pass if set to 2800. The minimum correlation coefficient to allow all to pass was 0.82 while the coefficient of 0.95 rejected all. Thus, both threshold levels can be adjusted to the need of speaker identification system, which is desirable for further study.

In this study, the mechanical properties of reactive powder concrete (RPC) with a constant cement to silica fume ratio of 4 were investigated. In the experimental program, reactive powder concretes with steel fiber at different ratios were produced. Five productions using quartz sand with a maximum grain size of 0.6 mm were performed. A superplasticizer with a ratio of 3% of the cement was used for all productions. $40{\times}40{\times}160mm$ prismatic specimens were prepared and tested for flexural and compression. The specimens were exposed to two different curing conditions as autoclave and standard curing condition. Autoclave exposure was performed for 3 hours under a pressure of 2 MPa. It was observed that the compressive strength of concrete, along with the flexural strength exposed to autoclave was quite high compared to the strength of concretes subjected to standard curing. The results obtained indicated that the compressive strength, along with the flexural strength of autoclaved concrete increased as the amount of cement used increases. Approximately 15% increase in flexural strength was achieved with a 4% steel fiber addition. The maximum compressive strength that has been reached is over 210 MPa for reactive powder concrete for the same steel fiber ratio and with a cement content of $960kg/m^3$. The relationship between compressive strength and flexural strength of reactive powder concrete exposed to both curing conditions was also identified.

This study investigated the effect of coated feed using mixed oil on rumen fermentation characteristics. Two experiments were conducted based on materials that were mixed. First, cashew nut and soybean oils were mixed with white mineral oil. And second, different plant extracts were mixed with white mineral oil. At first experiment, inclusion levels of mixed oil on diet (0.03%, 0.1%, 0.5%) were applied as variables. A coated diet was fermented with rumen inoculum according to in vitro rumen fermentation and its parameters were investigated. In the result of first experiment, no negative effects on rumen pH were found. Significantly decreased dry matter digestibility was detected at 0.5% treatment (P<0.05). Total gas productions in control and 0.03% were significantly greater than those of others (P<0.05). Significantly reduced methane productions were found in all treatments compared to the control (P<0.05). Inclusion of mixed oil did not affect on ammonia production. Total volatile fatty acid production was also not influenced by coating with mixed oils. Rumen fermentation parameters were greatly changed according to introduced plant extracts at second experiment. The significantly lowest and greatest ammonia productions were found at treatments with Ixeris dentata and Plantago asiatica, respectively (P<0.05). The significantly greatest acetate and propionate productions were detected at treatments with Crucuma longa and Zizyphus vulgaris 1, respectively (P<0.05). All treatments, except Chrysanthemum idicum, Euyale ferox seed, Moringa leaf and fruit and Zizyphus vulgaris 1, showed significantly increased total volatile fatty acid production compared to the control (P<0.05). Only Paeonia lactiflora showed significantly lesser gas production than the control (P<0.05). In methane production, Ceramium, Zizyphus, Paeonia, Agrimonia, Torilis, Mugwort, Foeniculum, Euphorbia, Taraxacum, Artemisia, Momordica, Curcuma and Moringa reduced methane significantly compared to the control (P<0.05).
