The Hong Kong film "Project Gutenberg" has obtained the great achievements at the box office and public reputation due to such multiple factors as realistic counterfeit banknote production process, breathtaking gunfight scenes, brain-burning plot, unexpected reversal ending, personal charm of Chow Yun-Fat and so on. In terms of film narrative, the director utilized the narrator, Li Wen, to guide the police and audience in the limited angle of perspective into the scheme, and make the symbolic meaning image of the actor Chow Yun-Fat stengthen the audience's confirmation for the imagination of "painter", with the introduction of multiple narratives and flashback of different characters and scenes, and then finally, used the narrative structure with multiple lines and layers to uncover the truth. There are three great reversals in the film, each of which is overthrow for the film plot, and every overthrow is a disavowal of the audience's cognition for the previous story; therefore it brings the greatly emotional tension, making the audience get complete release and relief in the process of the psychological game of cognition, identification and decision-making at the end.

The study was carried out to develop nursery soil for rice seedling of phyllite. First of all, physico-chemical properties of used phyllite in the study through the analysis for agricultural utilization evaluation are as following. Bulk density(BD) of phyllite was $1.31g/cm^3$ each other and porosity had 65% of entire pore size. Also, the water holding capacity(WHC) was 43% at 1/3bar pressure, which phyllite has high WHC. According to, the results the experiments for nursery soil were conducted by mixing the materials such as phyllite, zeolite and hill soil. The mixing ratios were 30, 50, and 70% for zeolite and hill soil into phyllite. These mixed materials were packed in a box by adding 0, 1 and 2g of N-fertilizer. At seedling test, there were increases in the growth of shoot and root of rice for phyllite to zeolite and phyllite to hill soil, respectively. On the other hand, the length of leaf increased with increasing application rate of phyllite, while length and a number of root increased with increasing application rate of hill soil. The growth in the plots of phyllite to zeolite and phyllite to hill soil was better than in control plot. Finally, phyllite plot had efficient results when it compared with others and the study used with phyllite will have to more research and effort for agricultural useful material.

Using multi-temporal KOMPSAT-3/3A high-resolution satellite images, the Normalized Difference Vegetation Index (NDVI) for the area around the Fukushima daiichi nuclear power plant was determined, and the pattern of vegetation changes was analyzed. To calculate the NDVI, surface reflectance from the KOMPSAT-3/3A satellite image was used. Satellite images from four years were used, and the zones where the images overlap was designated as the area of interest (AOI) for the study, and by setting a profile passing through highly vegetated area as a data analysis method, the changes by year were examined. In addition, random points were extracted within the AOI and displayed as a box plot to quantitatively indicate change of NDVI distribution pattern. The main results of this study showed that the NDVI in 2014 was low within AOI in the vicinity of the nuclear power plant, but vegetated area continued to expand until 2021. These results were also confirmed in the change monitoring results shown in a profile or box plot. In disaster areas where access is restricted, such as the Fukushima nuclear power plant area, where it is difficult to collect field data, obtaining land cover classification products with high accuracy using satellite images is challenging, so it is appropriate to analyze them using primary outputs such as vegetation indices obtained from high-resolution satellite imagery. It is necessary to establish an international cooperation system for jointly utilizing satellite images. Meanwhile, to periodically monitor environmental changes in neighboring countries that may affect the Korean peninsula, it is necessary to establish utilization models and systems using high-resolution satellite images.

This study aimed to optimize the culture conditions of recombinant Escherichia coli expressing otsBA using crude glycerol for the enhanced production of trehalose. The effects of culture temperature and isopropyl ${\beta}$-D-1-thiogalactopyranoside (IPTG)-induction were investigated. Trehalose production and cell growth were highest when cells were cultured at $37^{\circ}C$ and induced with IPTG. The concentrations of IPTG, validamycin A, and NaCl were optimized using Box-Behnken design. Statistical analyses of the experimental data revealed that the concentrations of IPTG and NaCl had significant effects on trehalose production, but that of validamycin A did not. Contour plot analysis and model calculation showed that the highest amount of trehalose could be produced at 298 mM NaCl and 0.1 mM IPTG. Under these optimal conditions, the optical density at 600 nm and trehalose production were $5.4{\pm}0.2$ and $304{\pm}15mg/l$, respectively.

This Paper aims to explore the key factors that drive box-office success in Korean, Chinese and Japanese film market regarding to the storytelling of the movies. At first, I researched the top 20 movies at the box office of Korean, Chinese and Japanese film market from 2007 to 2011.And then I tried to figure out the key factors for the success and the differences among those countries. Usually the purpose of the movie planning in Korea is for the domestic market. In the profit structure of Korean film industry, it is really hard to focus on the overseas film market. In Chinese film market, recently it has been changed a lot especially film genre. The movie liked to watch is melodrama, romantic comedy movie It is being changed to the comedy genre from the war and martial arts movie. And it is emphasized the importance of the scenario in the film production. They want to watch their lives like a real and dreams at the movie and the movie tries to show this trend. In Japanese film market, they made movies in which TV drama, animation and cartoon according to the O.S.M.U. strategy. The movies like to watch are the blockbuster movies, horror movies, thriller movies and melodrama. Comparing with Korea and China, they like movies which show more fantastic and fairy tale imagination.

This study compared and analyzed Korean, American, Singaporean, and Japanese middle school mathematics curriculum standards and the learning contents in statistics. Through a comparative analysis of the curriculums of these four countries, I found several overall features and differences between the curriculums. First, all four countries emphasized statistical education in a real-life context. Second, all four countries emphasized the use of technological tools. Third, there is a middle school grade in which only Korea does not deal with statistical domains. Fourth, the statistical areas of the United States, Singapore, and Japan focused on identifying trends or variability in data distribution. Fifth, I have found some contents that only Korea does not deal with. Based on this, the following recommendations were developed for the development of the next curriculum and new textbooks in Korea. First, the statistics curriculum should be changed from one that focuses on understanding statistical concepts to one that focuses on statistical activity that utilizes these concepts. Second, in terms of middle school statistical curriculum contents, the addition of interquartile range (IQR) and box plots as learning contents should be considered. IQR and box plots are simple and practical techniques for the comparison of multiple sets of data that can be easily learned and drawn by middle school level students and applied to real-life-related statistical data to expand statistical literacy. Through this study, it is suggested that IQR and box plots need to be included in the statistical curriculum of middle schools in Korea.

We consider practical experimental design strategies and analysis to find out whether a modified method give better results than the standard method. The most practical design strategy is for experimenter to make r successive runs under the current standard method and then, change the standard method to a modified method to make another r successive runs under a modified method. To test a statistically significant difference between the population mean of the standard method and a modified method, additional recent data for sufficient number of consecutive responses under the standard method is needed to construct external reference distribution(Box, et al., 1968). Upon those informations unavailable, the practical design strategy is to run the experiment by split plot designs. In this paper, two types of split plot designs are proposed and how to determine efficiently the number of repetition within a given method and replication of those two methods are discussed based on results of the level of significance ${\alpha}$= 0.05 and the power being at least 0.9 at the detectable difference of ${\mu}_2-{\mu}_1=1.5{\times}{\sigma}$.

During normal machine operation, partial discharge(PD) measurements were performed with turbine generator analyzer(TGA) in two high voltage motors. Two 6.6kV motors were installed with 80pF capacitive couplers at the terminal box. The PD patterns were displayed two dimensional and three dimensional. TGA summarizes each plot with two quantifies such as the normalized quantity number(NQN) and the peak PD magnitude(Qm). Off-line PD measurements were conducted on one 4.16kV motor. The motor was energized to 2.4kV, 3.0kV, 3.5kV and 4.16kV, respectively. The PD levels in pC were measured with a conventional digital PD detector. The comparison of positive to negative PD indicates whether the defect elements of PD are within the insulation or on the insulation surface. Discharge at conductor surface was discovered in No. 1 motor. Internal discharges were generated in phase A, B and C of No. 2 motor, Slot discharges occurred in three phases of No. 3 motor.
