  • The difference of generation is the main cause of society transition. If we know about the gap of generations, then we know where we go in future. This study focus on the differences of a regulation recognition among the generations. When we understand the differences of regulation recognition among the generations, we can realize the trait of regulation in society. In result, there are a lot of differences of regulation recognition among the generations. The older they are, the more they are positive to regulation. And the younger they are, the more they are negative to regulation. In particular, 50's generation have the opposite regulation recognition to 20's generation in specialty of regulation and in a conglomerate regulation.

  • The box tree pyralid, Glyphodes perspectalis, was reared on an artificial diet based on dried powder of box tree leaves, Buxus microphylla var. koreana, and INSECTA F-II (Nihon Nosan Co., Ltd) at a ratio of 3:7 (w:w) and analyzed in their developmental characteristics from $1^{st}$ to $4^{th}$ generation. The developmental period of larva reared on artificial diet was longer than that of larva reared on host plant. Significant difference in larval period was also observed between $1^{st}$ and other generation groups. Pupation rate was the highest in $4^{th}$ generation followed by $3^{rd}$, $2^{nd}$, $1^{st}$ and host plant group. Significant difference in pupal period was noted between $1^{st}$ and 3rd generation group. Emergence rate was the highest in $4^{th}$ generation group followed by $3^{rd}$, host plant, $1^{st}$ and $2^{nd}$ generation group. There is a significant difference in male and female size between $1^{st}$ and $4^{th}$ generation group. Our result indicated that stable rearing of box tree pyralid through the year is possible by artificial diet, and the best adaptation to artificial diet was achieved at $4^{th}$ generation.

  • In this paper, two automatic mesh generation algorithms are presented. The methods seek to optimize mesh density with regard to geometries exhibiting both fine and coarse physical structures. When generating meshes, the algorithms attempt to satisfy the conditions on the maximum mesh spacing and the maximum grading ratio simultaneously. Both algorithms successfully produce non-uniform meshes that satisfy the requirements for finite-difference time-domain simulations of microwave components. Additionally, an algorithm successfully generates a minimum number of grid points while maintaining the simulation accuracy.

  • Terahertz (THz) wave generation from bulk and periodically poled $LiTaO_3$ (PPLT) with a Cherenkov phase matching scheme is numerically investigated. It is shown that by using the crystal birefringence of bulk $LiTaO_3$ and a grating vector of PPLT, THz waves can be efficiently generated by difference frequency generation (DFG) with a Cherenkov phase matching scheme. The frequency tuning characteristics of the THz wave via varying wavelength of difference frequency waves, phase matching angle, poling period of PPLT and working temperature are theoretically analyzed. The parametric gain coefficient in the low-loss limit and the absorption coefficient of the THz wave during the DFG process in the vicinity of polariton resonances are numerically analyzed. A THz wave can be efficiently generated by utilizing the giant second order nonlinearities of $LiTaO_3$ in the vicinity of polariton resonances.

  • Purpose - This study aims to examine the relationship between Chinese employees' collectivism orientation and organizational commitment and interpersonal helping behavior and verify the differences of such relationships between new and the previous generation of employees. Design/methodology/approach - The 262 Chinese employees participated in self-reported survey through online platform. The confirmatory factor analysis and the hierarchical regression analysis were performed to test hypotheses. Findings - We found that Chinese employees' collectivism orientation positively influenced their organizational commitment and interpersonal helping behavior. Regarding the moderating role of generation, our result revealed that while the positive relationship between collectivism orientation and organizational commitment was significant for previous generation of employees, such relationship was not valid for new generation employees. However, there was no significant generational difference in the relationship between collectivism orientation and interpersonal helping behavior. Research implications or Originality - Considering that there have been relatively few empirical studies examining the interaction between employees' cultural characteristic and generations, this study contributes to demonstrate that the positive influence of Chinese employees' collectivism orientation on organizational commitment vary depending on Chinese generations. In addition, this study provides implications that organizational leaders in China should understand that the generational difference can influence how employees' collectivism orientation leads to their attitudes towards organizations and need to establish human resource management system by reflecting generational difference.

  • The Purpose of this research is to examine and contrast the cultural characteristics of the street fashion in new generations of Korea and Japan. We also intended to help clothing companies understand the current trend in this new generation. As the method for street fashion analysis. various literature, internet information and new media materials were utilized. Key observations obtained are as following First, they pursue a complex image. New generations seem to admix images from different areas to create a synthetic image, rather than adopting a single image; Second, practicality is an important factor. They Pursue a sense of their own unique trend: Third, distinction. The difference in society values between Koreans and Japanese is incorporated. The Korean new generation considers the traditional moral principles as important social values. In contrast the Japanese new generation is greatly influenced by the open sexuality culture ; Fourth. public ownership and sharing of the culture. There is a gradual deviation from a dominating unidirectional influence from one country on another. Now the two countries are influencing each other ; Fifth, sense. There are numerous fashion items and generalized total coordination. New generations express more active and creative fashion sense in those fashion items.

  • In this work, an one-dimensional analysis on spontaneous combustion in a coal stockpile was conducted using a commercial software $gPROMS^{(R)}$ based on assumption suggested by Arioy and Akgun. According to them, it is assumed that there is temperature difference between the surface of coal particle and the gas surrounded around the particle, and it is also assumed that the velocity of the gas is constant and thus oxygen is fed to the stockpile with same velocity. The higher temperature zone is formed to the surface of the coal stockpile at the initial phase and it became deepen as time is taken. Finally it was found that the temperature difference between coal particle and the gas was calculated as $57^{\circ}C$ and spontaneous combustion have not been occurred during 6 months since coal was piled in the stock.

  • The perception of aging experience and successful aging depends on birth cohort as Korean society has rapidly changed for the last several decades. This article aims to empirically explain inter-generational difference in the perceptions of successful aging with an emphasis on the social relationships using a national survey data set by face-to-face interviews with a structured questionnaire. The respondents are classified into colony war, restoration, democratization, and information generation. Major findings are as follows: The perceptive differences are found between colony war and restoration generation, and democratization and information generation. The difference are clear in the aspects of expectation for children and parents-children relationship. The inter-generational difference remains even after controlling other relevant factors. Policies and programs, therefore, should 1) attempt to help inter-generational understanding, and 2) consider the yet-existing uniqueness of each generation.
