  • The purpose of this study is to investigate the torso patterns by analyzing sensory evaluations. The anthropometric measurements for female college students were obtained between March and October in 1998, and a total of 197 anthropomatric data was used for the somatotype analysis. The appearance and fit of three kinds of torso patterns(ESMOD, FIT, and Muller & sohn) were evaluated by expert panel and the subjects. The results of the anthropometric measurements and sensory evaluations are as follows; The mean height of the anthropometric data for 197 students is 158.98cm. The largest proportion of the three somatotypes(H, M and A type) is big hip type(A type) consisting of 47.7% of all the respondents. The result of the torso pattern evaluations by expert panel indicates that the ESMOD pattern obtains the highest rating in general acceptability. A significant difference(p<.05) in the responses to two questions, the placement of the waist dart, and the gapping & creasing at back hip area was found. The ESMOD and Muller & sohn patterns are given the highest rating in the general acceptability. The result of the evaluation was obtained by the subjects. (Korean J.

  • Business going concern is an important issue to be addressed since it determines how companies will survive. One indicator of the going concern problem is going concern opinion. The going concern opinion is a result of evaluation of auditors on going concern assumption of financial reporting. This research aims to examine the effect of opinion shopping, prior opinion, audit quality, and financial condition on going concern opinion. Research sample consists of 80 listed manufacturing companies on the Indonesian Stock Exchange surveyed between 2013 and 2017. Analysis data uses logistic regression. Based on the result, prior opinion affects going concern opinion, while opinion shopping, audit quality, and financial condition have no effect on going concern opinion. The significant effect of prior opinion on going concern opinion indicates that auditors consider the evaluation of the previous condition of companies' concern problematic since going concern is hard to be solved in a short-term period. This research provides recommendations for companies to increase their business ability so going concern problem can be avoided. This research also suggests to auditors to consider prior opinion to issue current opinion since previous companies' condition can be used as a general picture to initiate the auditing process.

  • As our society is rapidly entering an aging society, interest in mobile health care services for disease prevention and health care for the elderly is increasing. To increase the usability of mobile healthcare services, UI design should be considered from an older person's perspective and a specific evaluation system is required to diagnose these UI usability levels. This study aimed to develop a UI usability evaluation area of mobile-healthcare application for the elderly. For this, we conducted a literature analysis to explore the comprehensive UI usability evaluation factors, and FGI for expert groups and user groups to derive UI usability evaluation areas and detailed evaluation factors. As a result, the usability evaluation areas for the elderly were divided into four areas 'design', 'contents', 'process', and 'system'. A total of 13 sub-factors and 32 detailed constructions have been derived.

  • In terms of both quality of rural lifestyle and cultural awareness, the importance of community facility is being emphasized. Nevertheless, by occasion of graying, population outflow and revenue loss, rural society faces the erosion of community. For these reasons, government is promotion an community space construction project on rural areas which is lack of community facilities. Whereas the projects are just one off thing not include upkeeping, so lots of functional overlapping community facilities are formed in same place. In this study has classified rural community facility remodeling element and designed rural community facility evaluation system of each elements. In order to implement of purpose, it has categorized community remodeling index in rural area by literature analysis and site survey. For setting remodeling rating system, this study analysed preceding research data and conducted a Delphi survey of 30 experts. As a result, this study deducted 29 categories of community remodeling index and 21 categorizes of remodeling rating clause. Taking this result, this study progressed case study on seonheul-ri in Jeju. Implications, limitations and future research directions are presented. It would be groundwork for remodeling system development in rural community facility.

  • Recently hydrogen fuel cell buses have been deployed for the public transportations. In order to introduce buses fueled by hydrogen successfully, the research results of hydrogen bus safety should be discussed and investigated significantly. Especially, Korean government drives research in terms of various applications of hydrogen energy to replace the conventional fuel energy resources and to improve the safety evaluation. Thus it is necessary to examine vehicle crashworthiness under side impact loadings. This study was focused on the simulation result evaluation of full bus model and simplified bus model with hydrogen fuel tank module and mounting system located below floor structure due to the significance of bus side impact accidents. The finite element models of hydrogen bus, fuel tank system and side impact moving barrier were set up and simulation results reported model performance and result comparison of two side impact models. Computational results and research discussion showed the conceptual side impact framework to evaluate hydrogen bus crashworthiness.

  • The present seismic analysis of Road-Bridge Design Standard is on a basis of load-based analysis which lets structures have the strength over load. In this study, the capacity spectrum method, a kind of displacement based method, which is evaluated by displacement of structure, is presented as an alternative to the analysis method based on load. Seismic capacity is performed about the existing reinforced concrete pier which has already secured seismic design by capacity spectrum method. As a result. capacity spectrum method could realistically evaluate the non-elastic behavior of structures easily and quickly and the displacement of structures for variable ground motion level. And it could efficiently apply to an evaluation of seismic capacity about the existing structure and a verification of design for capacity target of the new structure.

  • The pavement stiffness is scarcely used in structural analysis to design the superstructure of bridge. It is reasonable not to consider it in the case of asphalt concrete pavement over concrete deck because the pavement stiffness compared with the concrete deck plate can be ignored. However, sometimes, the pavement materials have a similar amount of elastic modulus to concrete and are applied to the orthotropic steel deck plate which has relatively less stiffness compared with the concrete deck plate. In this paper, the steel plate deck of a real bridge project was analyzed by considering the pavement stiffness by linear elastic FEM. It was assumed that a perfect bond between the steel plate deck and the pavement exited. The results indicated that the structural behavior of the orthotropic steel deck plate can be estimated enough to affect the evaluation result of structural capacity in some cases. Therefore, the investigations by experimental tests and more advanced numerical model are indispensible in figuring the design formula for considering the effects of pavement stiffness in the structural analysis of an orthotropic bridge.
