The present paper is concerned with the development of the computational biology in the past half century and its relationship with combustion. The modem computational biology is considered to be initiated by the work of Alan Turing on the morphogenesis in 1952. This paper first touches the life and scientific achievement of Alan Turing and his theory on the morphogenesis based on the reactive-diffusive instability, called the Turing instability. The theory of Turing instability was later extended to the nonlinear realm of the reactive-diffusive systems, which is discussed in the framework of the excitable media by using the Oregonator model. Then, combustion analogies of the Turing instability and excitable media are discussed for the cellular instability, pattern forming combustion phenomena and flame edge. Finally, the recent efforts on numerical simulations of biological systems, employing the detailed bio-chemical knietic mechanism is discussed along with the possibility of applying the numerical combustion techniques to the computational cell biology.

The aim of this study is to analyze the relationships and propose the desirable relationships between mathematics curriculum and curriculum-introduction. Under the purpose of this study, we investigate the coherence of mathematics curriculum and curriculum-introductions which have been revised through the seven curriculum-revisions to the present. And we analyze the change in the education. On the basis on this analysis, we propose mathematics textbooks which can be said that have a strong impact on the practice of mathematics the important points that should be considered in the mathematics curriculum-revision. First, we need to reconsider the order of the mathematics curriculum-revisions which has been going on from curriculum-introduction to mathematics curriculum. Second, we should take more efforts in developing the mathematics textbooks and reflect the voice of the mathematics textbooks and reflect the voice of athematics leachers in the more positive way.

Since software development team members have been more geographically spread due to the globalization of business and Internet technologies, the management of deliverables and communication efforts for developing high-quality software products on time is becoming more complicated. Among the functional requirements for collaborative software development management, the manipulation of shared information objects is essential for the collaborative work among distributed development team members. This paper proposes an integrated information object management framework comprised of a so-called BOC (Bill Of Class) scheme and a standardized software part dictionary for managing shared information objects efficiently among distributed co-workers. In order to manage these complex information objects, the proposed framework adopt product structures represented by Bills Of Materials (BOM) as stems for integrating the various information objects. Based on the proposed framework, a collaborative software development management system (CSDMS) is implemented, and the functionalities and the structure of the system are also described in this paper. The proposed system provides sufficient functionalities for the change management of information objects and the management of their relationship to other objects rather than existing system.

International efforts have focused recently on the development of tungsten surfaces that can intercept energetic ionized and neutral atoms, and heat fluxes in the divertor region of magnetic fusion confinement devices. The combination of transient heating and local swelling due to implanted helium and hydrogen atoms has been experimentally shown to lead to severe surface and sub-surface damage. We present here a computational model to determine the relationship between the thermo-mechanical loading conditions, and the onset of damage and failure of tungsten surfaces. The model is based on thermo-elasticity, coupled with a grain boundary damage mode that includes contact cohesive elements for grain boundary sliding and fracture. This mechanics model is also coupled with a transient heat conduction model for temperature distributions following rapid thermal pulses. Results of the computational model are compared to experiments on tungsten bombarded with energetic helium and deuterium particle fluxes.

This research aims to provide empirical basic data for the development of local communities through the establishment of efficient strategies for the formation of positive relations between the club and the region through the Creation of Shared Value (CSV) activities. We come up with the results of this study to show that CSV, social problem orientation, and core competency utilization affect the team trust of local community, and that CSV, long-term orientation, social problem orientation and core competency utilization affect community identification. The research should enhance the value of professional sports teams that promote their own path to self-sustaining as a single independent business area, and identify their trust through CSV activities for co-prosperity with their local communities, and thus their relationship with the community. Therefore, various strategies and efforts will ultimately increase the team trust and community identity of local residents in professional volleyball teams, while at the same time gaining positive effects on professional volleyball teams.

In last few decades Food and Beverage industry has being treated as an important sector in modern industrial society due to more disposable income and the changes of social, and cultural life style in Korea. Especially the kitchen takes part in an important role in F&B industry and it's study should be done in various aspects. therefore, this study is focussed on the efficient organization and operation of the kitchen. Organization means act of organizing or condition of being organized or organized system. In this study, organization is being examined on the background of the organization theory from the industrial revolutionary period untill present. And the Korean cooking history which takes part of kitchen organization has been analyzed and compared with that of the Western. The improved kitchen organization was presented through all the above in this study. And all the efforts toward the development in kitchen organization to be tried under the close relationship with the technological, ,kitchen functional, managerial and concerned subsidiary systematic situations. We can try to improve the creativeness and progress for organization through all these challenges.

Objectives: The purpose of this study is to examine the level of community environmental perception of older adults and to identify the association between environmental perception and subjective health status among older persons. Methods: Analyses are based on data from Statistics Korea 2016 Social Survey. This study analyzed a total of 8,193 older adults aged 65 and over, and examined the association between environmental perception on air, water, soil, noise and vibration, and subjective health status using multiple regression analysis. Results: Study findings shown that environmental perception on water and soil had significant association with subjective health status of older adults. Specifically, older adults reported worse health status when they had more negative perceptions of water and soil environments in their communities. Conclusions: Results of this study suggested that efforts to enhance safety of drinking water and soil environments, and continuous research to identify relationship between environment and elderly health shoud be needed.

The increased popularity of group-buying deal promotions has made research efforts grasping the importance of involvement on the positive reactions of consumers. This is due to the fact that consumer purchasing behaviors are highly likely to differ depending on a particular consumer's involvement level, referring to the basic interest in or importance of a group-buying purchase. In this regard, this paper (1) investigated the effects of involvement on purchase behaviors; and (2) examined whether the proposed relationships may vary depending on a consumer's deal prone propensity. Results revealed that a consumer's cognitive involvement in a restaurant promotion affects emotional involvement, ultimately leading to purchase intention. In addition, a consumer's deal proneness tendency was revealed to moderate the relationship between cognitive involvement and emotional involvement. Compared to low deal-prone consumers, high deal-prone consumers tended to have a higher level of emotional involvement resulting from cognitive involvement. Managerial implications and directions for future research are provided.

(1) The correlation between the mass of supermassive black holes (SMBHs) and the properties of their host galaxies suggests that SMBHs and host galaxies are closely linked in their formation and evolution. While the exact origin of their relationship is still under debate, theoretical models often invoke feedback from active galactic nuclei as a crucial mechanism for establishing the BH-host correlation. In the first part of my talk, I will present our efforts to find observational sign of the AGN feedback in young luminous AGNs. (2) While intermediate-mass black hole (IMBH) is thought be cosmologically important class to understand the link between stellar mass black holes and SMBHs, it is extremely rare in the present-day Universe. In the second part of this talk, I will report a Gemini/GMOS-N IFU study of an ultraluminous X-ray source in NGC 5252, which is a possible candidate of an off-nuclear non-stellar black hole.
