The concepts of static seat allocation model has been used widely in the air transportation industry, and proven as a good concepts for managing perishable assets. The paper analyzed, in realistic environment, the volume of Accept Demand and Reject Demand through several times' simulation experiments at each fare level by using C-Program analyzing process applied to upward and downward models of demand, to analyze the change of fare level when upward and downward shifts of fare levels' demand happen at once. As a consequence, I concluded that the revenue of the case to consider the both shifts of demand at each fare level is bigger than that of the case to consider the single shift of demand at each fare level, except the case to downsize the seat allotment at very low price when supply is bigger than demand, with developing a general model concerned with plural fare levels.

Cultural contents refers to cultural and artistic contents that are saved, sold, and enjoyed in various digital media. In responding to rising content contents, OSMU has been utilized to make one content into various types of products. Recently, transmedia contents are replacing the role of OSMU. Transmedia contents builds up the united content with blending of various contents through plural media and they have emerged in the part of creating digital contents under the convergence paradigm. Transmedia contents becomes invasive and permeates fully the audience's lifestyle by developing content available across multiple forms of media. This study discusses the differences between OSMU and transmedia contents. It attempts to clearly define transmedia contents and to conceptualize the components of transmedia contents. In doing so, this study seeks a new method of storytelling utilizing transmedia contents. The discussions in this study should be useful for transmedia content developers to improve their work. Implications and directions for future study are discussed.

The retention of solutes in reversed-phase high-performance liquid chromatography depends on their hydrophobicity. Although the retention behaviors of alkyl benzenes have been reported so far, quite a few authors have mentioned the retention behavior of alkyl benzenes with plural hydrophobicity parameters. In this sense, we were interested in the retention behaviors of alkyl benzenes having benzene moiety and increasing alkyl chain. In this study, we therefore investigated the retention behavior of alkyl benzenes in reversed-phase high-performance liquid chromatography in order to obtain information concerning the effects of the aromatic moiety and the carbon chain on the retention mechanism by comparing their capacity factor (k') in relation to the carbon chain length. The eluent acetonitrile ($CH_3CN$) showed high selectivity on alkyl benzenes, showing the high difference of capacity factor (${\Delta}log\;k'$) between toluene and octyl benzene. Indeed, the ${\Delta}log\;k'$ of 80% $CH_3CN$ represented 1.42- and 4.25-times longer than 90% MeOH and 60% THF, respectively. The hydrophobicity parameters, van der Waals volume, bond constant, partition constant, $\pi$-energy effect and enthalpy were evaluated with the capacity factor (k') of alkyl benzenes eluted on 80% CH3CN, 90% MeOH and 60% THF, respectively. The best eluent for predicting retention behavior of alkyl benzenes was 90% MeOH ($R^2$ 0.999). The three parameters, van der Waals volume, bond constant and partition constant were well coincident to log k' by increasing alkyl benzenes. However, $\pi$-energy effect and enthalpy were severely disagreeable. Taken together, van der Waals volume, bond constant and partition constant were a reliable parameters to predict the retention behaviors of alkyl benzenes on reversed-phase column.

The purpose of this study was to understand sexuality expressed in fashion in a discursive view and reinterpret sexuality represented in fashion in the 19th century in Foucauldian post-structural perspective. As for methodology, at first the conception of sexuality was examined from structural feminism to post-structural pluralism by a literature review and discussed in relation with the matters of body and fashion on the basis of Foucault's discourse. Then, sexuality represented in the 19C fashion as a case study was re-estimated in terms of power relationship between dominant and oppositional discourses and mainstream fashion and anti-fashion as well. The conception of sexuality in Foucauldian post-structuralism maintains the view of plural sexuality, which floats by discourse and power produced in a specific historical context. In the Foucauldian perspective sexuality expressed in the mainstream fashion and anti-fashion in the nineteenth century shows the following aspects. The mainstream fashion in the middle and latter of the 19C made the clear sexual difference in dress of plain and functional male suit and extravagant and decorative female dress on the center of bourgeois masculinity in the context of modernity and capitalism. Although anti-fashion was also co-existed with the mainstream fashion, it was criticized by the Victorian people. It codifies sexual ideology of the binary opposition of male domination and female subordination. Therefore, the traditional sexual ideology in the 19C is a capitalist value, which gives a priority to bourgeois man's profits, and the Victorian discourses of sexuality constructs the clear sexual difference in dress in the period.

The purpose of this study is to typify femininity and masculinity represented in mainstream women's and men's fashion magazines in Korea since 2000 and infer sexual ideology appearing in contemporary Korean society by content analysis with the view of plural sexuality. For the content analysis total 259 editorial fashion photography was analyzed. As the result, 5 femininities and 5 masculinities were typified, and then sexual discourse was inferred out of the frequency of each type and texts with the images. On the basis of previous studies and historical considerations of this topic, the types of sexuality represented in mainstream fashion magazines in Korea since 2000 were classified as follow.: in women's fashion magazines Traditional Femininity and Androgynous Femininity were almost similarily dominant sexuality, and Glamor Femininity, Babydoll Femininity, and Genderless sexuality were alternative. Meanwhile, in men's fashion magazines Traditional Masculinity formed clear dominant sexuality, and Macho Masculinity, Androgynous Masculinity, Adolescent Masculinity, and Genderless sexuality were alternatives. In addition, Androgynous Masculinity in women's fashion magazines occupied the highest frequency, while Glamor Femininity in men's fashion magazines did so. From this sexual discourses represented in mainstream fashion magazines in Korea since 2000 are as follow.: First, mainstream fashion in Korea sticks to the modern values preserving traditional sexual ideology even in this postmodern period of the former 21C. Second, Androgynous Femininity as another dominant femininity with Traditional Femininity connotes the change of conception of femininity in Korean society. Third, Androgynous Masculinity to females is preferred, while femininity to males is still regarded as fetish or adorned object. Fourth, the appearance of various alternative sexualities leads to pluralization of sexuality, and then fashion gradually codifies youthfulness and feminine values, such as body and sexual desire more than before.

This research aimed to determine how a combined yoga and tea meditation program would affect the happiness of adolescents. The investigation was conducted over a total of 11 sessions held twice a week with 15 female middle-school students. Each session lasted 90 min and comprised preparation for 5 min, Hatha yoga for 50 min, tea meditation for 15 min, the expression of feelings for 15 min, and 5 min were allocated to finishing the program and announcing the next session time. A t-test was performed before and after the program to analyze the effects of the program. A goodness of fit test, which is related to the improvement of happiness, was done through a path analysis. As a result, we were able to determine meaningful changes in the t-test scores of happiness, stress, and quality of life. The scores of mindfulness, physical self-concept, and self efficiency changed positively, but meaningful changes were not shown. To derive a final conclusion, we verified the mediator effect with respect to happiness through a structural model. Consequently, physical self-concept was activated as a promoter for improving self-efficiency and mindfulness. Mindfulness was the key factor that improved the happiness of the adolescent subjects.

A banknote counter is a machine that automates counting the money in some agencies to treat much banknotes as well as general banking agencies. The banknote counter materialized in this paper is the machine that adds the function of banknote sorting, detecting plural banknote and detecting counterfeit banknote to an existing banknote counter. The technique of sensor signal processing are used for banknote sorting. The technique of sensor application and data processing are used for detecting counterfeit banknote. The technique of precision equipment design and microprocessor application are used for high speed count. Software improved in debugging and difficulties to link with additional hardware. It was materialized through effective control algorithm and real-time signal processing with C-language on the basis of RTOS(real-time operating system) Photodiode, its applications and a magnetic resistance sensor are used as a sensor device with regard to hardware cost -cutting and process velocity. PCF80C552-24 of Philips using Intel I8051 core is used as a control microprocessor. As the results so far achieved, counterfeit banknotes made by the use of a color duplicator and a color Printer, are distinguished from real banknotes through mixing an optical with a magnetic sensor. and, in case that there are some different banknotes while counting, it is prevented for them to be counted without discriminating from the same kind of banknotes in addition to the fu notion of banknote sorting.

In ubiquitous geographic information environment, the users are provided with geographic information anywhere and any time on their needs by any types of devices and communication media. The unique location ID, ePosition, is a new technology to support UBGI environment, using a logical location ID instead of physical location of a point of interest. Domain names of plural ePosition servers, where location information with its ePosition is stored, needs to be registered in DNS for some service through Internet. For better ePosition service of the type of public service like email service, a set of DNS resource records can be newly defined. This paper suggests a new DNS resource record EPO for implementation of the ePosition service through Internet.
