This study analyzed the factors that viewers consider when watching anime on Over The Top(OTT) service platforms and the characteristics of each type of preference, which are the components of anime preference. To this end, the survey data of 240 animation major students were used for analysis, and the conclusions drawn through frequency analysis and cross-tabulation of IBM SPSS Statistics 27 are as follows. Netflix is the OTT service platform that viewers use the most, and TV series are the most preferred for animation works. In addition, it was found that Netflix OTT original animation works were preferred over other platforms, and long-form animation preferred Disney+. Among the characteristics of each type of animation preference, it was found that the factors considered when watching animation in terms of narrative value, aesthetic value, and entertainment value respectively value the structure, screen production, and immersion of the storyline. It is hoped that this study will be used as useful data for producing animation contents with the OTT service platform.

As the use of mobile devices such as PDAs and smart-phones increases, the Mobile Payment System(MPS) is widely used as a new payment method. Accordingly, domestic and foreign MPS users can conveniently purchase or use the products and services they want, free from the constraints of time and space. In this situation, the study was to investigate how the perception of MPS value varies depending on the characteristics of MPS users(demographic characteristics, MPS usage characteristics), and to analyze whether the perception of MPS value ultimately has a significant effect on user satisfaction. To accomplish these research purposes, the study conducted a statistical analysis using a questionnaire for people with experience using MPS in Korea. The analysis results of the study could be useful in seeking ways to successfully spread of MPS at home and abroad and improve user satisfaction in the future.

This study sheds light on the viewing experiences with ≪Game Society(2023)≫ through literature review and quantitative methodology to analyze the perceived value, the perceived experience quality, the attitude toward the exhibition, and the intentions to use of the exhibition. Survey participants demonstrate a tendency to rate the entertainment value higher than the esthetic and educational values. The aforementioned hedonic value shows a significant positive correlation with the degree of satisfaction, while educational and esthetic values exhibit negative corr)elations. Regarding the perceived experience quality, the attractiveness of the exhibition themes significantly influences the degree of satisfaction. Hypothesis testing results indicate that the five detailed factors related to the intention to use of the exhibition are significantly positively correlated with both the degree of satisfaction and the degree of immersion.

The urban atmosphere is characterized by th difference in surface and atmospheric environment between urban and more natural area. To investigate th climatic effect of land use type and anthropogenic heat of urban on wind field, numerical simulations were carried out under typical summer synoptic condition. The wind model PNU_MCM(Pusan National University Mesoscale Circulation Model) is based on the three-dimensional Boussinesq equations, taking into account the hydrostatic assumption . Since lane-use differs over every subdivision on Pusan the surface energy budget model includes sub0grid parameterization scheme which can calculate the total heat flux over a grid surface composed of different surfaces. The simulated surface wind agrees well with the observed value, and average over 6 days which represent typical summer lan-sea breeze days, August 1998, i.e. negligible gradient winds and almost clear skies. Urbanization makes sea-breeze enhance at day and reduce land-breeze at night. The results show that contribution of land-use type is much larger than that of anthropogenic heat in Pusan.

Recently, amount of High-Rise Mixed-use Building is Increasing based on Preference of comfortable residence and good view. Government policies were turned to prefer about High-Rise Mixed-use Building because of decreased real estate Condition. But these changes have revealed that it has many maintenance problems for example- efficiency, economic, environmental problems. This paper suggests that the Database System based on various alternatives and real case. And it will be a tool in the scientific decision and value analysis from the facility management to make optimized decision.

Ultrasound visualization is a typical diagnosis method to examine organs, soft tissues and fetus data. It is difficult to visualize ultrasound data because the quality of the data might be degraded by artifact and speckle noise, and gathered with non-linear sampling. Rendering speed is too slow since we can not use additional data structures or procedures in rendering stage. In this paper, we use several visualization methods for fast rendering of ultrasound data. First method, denoted as adaptive ray sampling, is to reduce the number of samples by adjusting sampling interval in empty space. Secondly, we use early ray termination scheme with sufficiently wide sampling interval and low threshold value of opacity during color compositing. Lastly, we use bilinear interpolation instead of trilinear interpolation for sampling in transparent region. We conclude that our method reduces the rendering time without loss of image quality in comparison to the conventional methods.

The purpose of this study is to examine that we can estimate land use by land values in 5 great cities. For this purpose, I calculated the percentage that each lot value makes up of the highest land values in the city as a indicator. I think this rate is very useful in the comparative study about many cities. At first, I set up four hypotheses based on my preceding studies. Hypothesis 1, the range of CBD can be estimated as having about 10% of the peak land values. Hypothesis 2, when the peak rate of concentric circle of land values seperated from CBD circle is about 30% of the peak land values, that is sub-CBD. Hypothesis 3, generally, a lot of having about 5% of the peak land values represents residential land commercial land use. Hypothesis 4, a lot of having about 3% of the peak land values represents only residential land use. The data on land values in five great cities were got from public notification on land values(1999) of the Ministry of Construction & Transportation. I selected highest lot values from many standard lot value in each Tong(the minimum administrative unit) in each cities. And I drew land values isopleth. Through that isopleth, I identified CBD cmd sub-CBD. Through the book of public notification on land values, I identified what land use are lots of having over 10%, about 5%, below 3% of the peak land values. As a result, we identified land use can be estimated by the percentage that each lot value makes up of the highest land values in the city. The bigger urban size becomes and the more stable land use becomes, the higher fitness of hypotheses becomes. The lowest degree of fitness about 4 hypotheses among 5 great cities showed in Inchon. Because Inchon lies adjacent to the greatest Seoul. The percentage that showed the lowest degree of fitness is 5% of the highest land values. The land use on lots of having about 5% of the peak land values is different from each other according to regional character in city.

This study details the history and characteristics of consumption values, text style analyses, and appeal types expressed in magazine commercials from 1955 to 2008. This study analyzes the level of the social structure of commercial expression for each period. Consumption values based on the categories of consumption values by Sheth (1991) were classified through a total commercials analysis. Analyses on closing types of sentences, types of sentences, and rhetorical figures were executed focusing on headline text and text style. Appealing types were composed of rational, emotional, and ethical appeals. For analysis, the crosstab analysis and chi-square test of SPSS are used. The results are as follow. Seven values were constructed, functional value, social value, emotional value, conditional value, epistemic value, fashionable value, and indistinct value. The ratio of emotional value was the highest and functional value, epistemic value conditional value, fashionable value, social value, and indistinct value followed. The emotional value social value, conditional value, fashionable value, and epistemic value that focused on the emotion of consumers increased, while the functional value decreased. Sentences that use narrative styles, hyperboles, and metaphors that increased the interest of readers were dominantly used in the headline texts. For sentence expression, a declarative sentence in a sentence type, exciting curiosity in the expression method where hyperbole and figures of speech in rhetorical expressions are used most often. Emotional appeal was used almost twice more than the reasonable appeal for appeal types of the total commercial. The lower level of reasonable appeal is information that provides the product function. Interest and expression (such as pleasure and achievement) were used most often for emotional appeal. These results show that the most important issue is the emotional value in consumption in understanding the consumer. Marketing managers should also be aware of the functional value as well as an emotional value.

Unlike the feature of SNS, which strengthens two-way communication and promotes interaction through consistent on/off line identity management, passive use of Facebook to unilaterally accept other people's opinions is being strengthened, and more people tend to use Facebook anonymously or pseudonym to enjoy freedom of expression. To illustrate this transformative use behavior, this study suggests an integrated model including psychological and behavioral variables such as self-esteem, real name use, and opinion expression to explore the effect on social relationship value perception and satisfaction. Studies have shown that self-esteem affects the use of real names and self-exposure, and that the satisfaction and sustainability of relationships have increased as real-name users expose more information about themselves.

To investigate the safety of the in-use vehicles emission against the tail-pipe emission regulation, in-use vehicles emission trend according to vehicle mileage should be known. But it is impossible to collect all vehicles emission data In order to know that. Therefore, it is necessary to establish a statistically meaningful inference method that can be used generally to estimate in-use vehicles emissions distribution according to the vehicle mileage with relatively less in-use vehicles emission data. To do this, a linear regression model that solved the problems of data normality and common variance of error was studied. As a way that can secure the data normality, In(emission) instead of emission itself was used as a sampled data. And a reciprocal of mileage was suggested as a factor to secure common variance of error. As an example, 36 data of FTP-75 test were handled in this study. As a result, using average value and standard deviation at each mileage which were inferred from a linear regression model, probability density distribution and cumulative distribution of emissions according to the vehicle mileage were obtained and it was possible to predict the deterioration factor through full useful life mileage and also possible to decide whether those in-use vehicles will meet the tail-pipe emission regulations or not.
