The purpose of this study is to investigate the effect of body type(thin, standard, fat), necktie width(narrow, medium, wide), gender(man, woman) on image formation. Sets of stimulus and response scales(7 point semantic) were used as experimental materials. The stimuli were 9 color pictures manipulated with the combination of necktie-width and body type using computer simulation. The subjects were 116 male undergraduates and 99 female undergraduates living in Gyeongsangnam-do. Image factor of the stimulus was composed of 4 different components, young-activity, attractiveness-gracefulness, stability, and boldness. In the young-activity, attractiveness-gracefulness and stability, body type and necktie-width showed independent effect. In the boldness, body type showed independent effect. Significant interaction effects of body type and necktie-width on young-activity, attractiveness-gracefulness and stability were found. For young-activity image, necktie of narrow width were effective. For attractiveness-gracefulness image, body type of standard were effective. For stability image, body type of standard and body type of thin on necktie of narrow and medium width were effective. The male fashion image can be perceived differently according to combination of the clues used in body type and necktie-width. Therefore, when the male fashion to create images that will have to consider the body type and necktie width.

As the demand for smart phone user is rapidly increasing in recent years, the development of new mobile communication system which provides more improved quality compared to existing 3G standard is highly requested. In this point, the long-term evolution (LTE) system, which was being developed in mid of 2000's, has attracted a considerable attention. The LTE has been developed continuously to result a release 10 which is called as LTE-Advanced (LTE-A) in 2010. Among various features in LTE-A, the multiuser MIMO (MU-MIMO) design is expected to give better quality for throughput, spectral efficiency, and latency. In this paper, we first review the development process from LTE to LTE-A. We also provide the overview of design challenges and specific solutions for MU-MIMO systems developed in LTE-Advanced standard.

This article analyzed the recent Korean accessibility standard supporting the people with disabilities. This is the basic study to make the interior environment more comprehensible and safer for the physically handicapped. Researcher selected the interior elements related to the mobility and accessibility for the physically handicapped. Then the '98 Korean accessibility standard code called 'Pyunui Chungjin Pup' were compared with the previous Korean building code and two other guidelines for evaluations. Result showed that 'Pyunui Chungjin Pup' addressed more obligatory items in facilities used by people with disabilities. That contributed to develope the accessible environments and to offer the independent activity in the society for the disabilities. However dimensions of 'Pyunui Chungjin Pup' showed the minimum standard. Also it did not provide the sufficient design considerations to make up the sufficient design considerations to make up the other types of disabilities including sensory limitations, or cognitive function limitations. Hereafter, the quality of accessibility guideline should be raised with further study.

The growth of the World Wide Web and the advances in high-speed network access have greatly changed existing CAD/CAE environment. The WWW has enabled us to share various distributed product data and to collaborate in the design process. An international standard for the product model data, STEP, and a standard for the distributed object technology, CORBA, are very important technological components for the interoperability in the advanced design and manufacturing environment. These two technologies provide background for the sharing of product data and the integration of applications on the network. This paper describes a distributed CAD/CAE environment that is integrated on the network by CORBA and product model data standard STEP. Several prototype application modules were implemented to verify the proposed concept and the test result is discussed. Finite element analysis server are further distributed into several frontal servers for the implementation of distributed parallel solution of finite element system equations. Distributed computation of analysis server is also implemented by using CORBA for the generalization of the proposed method.

This paper presents an efficient secure scan design technique which is based on a fake key and IEEE 1149.1 instruction to protect secret key from scan-based side channel attack for an Advanced Encryption Standard (AES) core embedded on an System-on-a-Chip (SoC). Our proposed secure scan design technique can be applied to crypto IP core which is optimized for applications without the IP core modification. The IEEE 1149.1 standard is kept, and low area, low power consumption, very robust secret-key protection and high fault coverage can be achieved compared to the existing methods.

The technical data for transmission line design and maintenance are calculated by a very complicated numerical formula so it is almost impossible to solve them by hand. Therefore the TOWER+ EXPERT SYSTEM was developed to systematically support technical data for transmission line design and maintenance. This system is able to calculate technical data which is applied to all conductors in our county, - that is 12 kinds of systems with 86 numbers of standard conductors, - and is programed to be user friendly by adopting dialogue windows, menu selection functions. Moreover, it minimizes input data by automatically providing standard transmission line design data, and it includes guidance of applicable work, program usage, data input process, help, explanation of terms and automatic error recovery functions that even a beginner can easily use.

Since 1990s, we have achieved a certain level of success in standardization of design, construction, and material on housing and public buildings with the national-level promotion. A practical connecting device that can synthesize all the serial processes is required to maximize the effect of construction material standardization. However, desired outcome of the standardization is not achieved yet because these serial standards and notification practices are decided by each part of the process and some are congested. In this study, we aim to improve a general organizational system of Korean Industrial Standard (KS) which is the most fundamental tool for the standardization of construction materials moving from a conventional idea that the standard is only for the material and components producers to a concept that can also be shared by the designers and construction workers. To achieve this, we propose an improvement plan for the Korean Industrial Standard in the perspective of three-tier classification system.

To realize the global standard of the assembly facility, one of key point is an influence of local characteristic. The global standardized information could be a useful input, especially at the beginning stage of the project. The content should be carefully checked against local requirements, in order to develop an Assembly Facility design to meet local regulations & characteristics. The level of input information required in each step is different depend on regions & countries. At an execution stage of the project, the global standard input needs to be updated as customized final input for the construction. There will be many issues to be clarified and coordinated so that the Assembly facilities meet the final requirements for the production technology. As a result, it is important to understand the timing to use the global standard information and the contents what is needed to adapt to the local characteristics. And close collaboration between production technology team and facility team is always required.

The objective of this study is theoretical and empirical evaluation of the flexural performance of concrete filled pretensioned spun high strength concrete pile with ring type composite shear connectors (CFP pile). The specimens are comprised of standard CFP pile, PHC pile+composite shear connector+filed concrete (CFP-N-N), standard CFP pile with $1^{st}$ reinforcements (H13-8ea), and standard CFP pile with $1^{st}$ and $2^{nd}$ reinforcements(H19-8ea). Flexural performance evaluation results showed that the ductility is improved with increased steel ratio, which leads to the increased maximum load by 46.4% (with $1^{st}$ reinforcement) and 103.9% (with $1^{st}$ and $2^{nd}$ reinforcements) compared to standard CFP ( CFP-N-N). Comparing with the predicted ultimate limit state values of the CFP pile design method and the experimental results, the design method presented in this study is reasonable since safety factor of 1.23 and 1.40 times for each reinforcement step are secured.
