A new finite elemetn approach is introduced for direct prediction of bland shapes and strain distributions from desired final shapes in sheet metal forming. The approach deals with the geometric compatibility of finite elements, plastic deformation theory, minimization of plastic work with constraints, and a proper initial guess. The algorithm developed is applied to cylindrical cup drawing, square cup drawing, and fron fender forming to confirm its validity by demonstratin reasonable accurate numerical results of each problems. Rapid calculation with this algorithm enables easy determination of various process variables for design of sheet metal forming process.

This paper focuses on how the coupling of the columns and walls through the structural slab contributes to the overall stiffness and strength of lateral systems. The rationale and procedures behind the design approach, which may offer a shift from more conventional assumptions made regarding compatibility and connectivity of gravity and lateral structural systems, will be introduced. The impacts on serviceability and strength design will be discussed, and observations on key design and analysis approaches will be featured. Mass and stiffness assumptions will also be reviewed. A case study on the topic will be presented describing implementation of slab coupling into engineering of a building project.

In the paper, we propose a design method and process of a hybrid V2X communication module that combines WAVE communication, LTE-V2X communication, and legacy LTE communication in evaluating vehicle V2X electromagnetic compatibility. C-ITS is suitable for safety service applications due to its low latency, and legacy LTE is suitable for applications such as traffic information and infotainment due to its high latency and high capacity. In order to evaluate the V2X communication system, the evaluation equipment must have communication performance of the same level or higher. The main design contents presented in this paper will be applied to the implementation of a hybrid V2X communication module for electromagnetic compatibility evaluation.

This paper describes a 32-bit RISC processor, which has instruction level compatibility with the ARM7 microprocessor. The processor is fully synthesizable, and its performance is evaluated based on 0.35-${\mu}{\textrm}{m}$ CMOS library. This paper focuses on the implementation of the processor and the reliable verification strategy ensuring the complete instruction level compatibility. The processor has successfully verified using a FPGA chip.

Purpose: This study aimed at exploring the product choice tendency differences between the consciousness and unconsciousness of goal orientation when product attributes is perceived to be compatible with the goal orientation. Research design, data and methodology: Empirical study used a 2 (goal conscious vs. unconscious) × 3 (hedonic vs. performance vs. reliability attribute) between-subjects design and one control group. To verify hypotheses, χ²-test was conducted to 320 questionnaire data answered by undergraduate students of Jiangxi Normal University in China. Results: First, consumers under unconscious condition showed a higher product choice consistency based on compatibility between hedonic (performance) attribute of the product and their hedonic (performance) promotion goal-orientation than those under the conscious condition. Second, product choice effects of compatibility between reliability attribute of the product and prevention goal orientation were not significantly different between consumers' consciousness and unconsciousness of their prevention goal orientation. Conclusions: Marketers of 'under dog' should try to develop and deliver the product attributes different from the attributes of 'top dog.' And the 'top dog' marketers should help their customers to avoid the conflicts by developing the environment of inducing their goal orientation unconsciously. Brand marketers should always pay attention to the reliability attributes concerned with the prevention goal orientation.

This study devised and drew custom sleeve patterns by using a regression equation with the data from 7 models along with the sleeve that was slightly modified to make the general-purpose sleeve pattern. To devise a general-purpose sleeve pattern, the sleeve pattern was drawn as an object for comparison by applying the Bunka drafting system (sleeve pattern by the Bunka drafting system) to the basic upper garment. Actual sleeves, made by using the three types of patterns above, were created and tested by models. Next, 30 panel members participated in a sight test of the compatibility of the sleeves to examine the validity of the sleeve drafting method acquired using the regression equation. The test proved that the custom sleeve pattern and the general-purpose sleeve pattern were more suitable for the characteristics of arm structures. Thus, the new sleeve-cap part drafting method using the regression equation was shown to have validity. As a result, since a very significant correlation was obtained for the body measurement figures and the basic pattern of the adequate basic pattern of the sleeves, this study concludes that it is possible to come up with primary data that can be widely used by increasing the number of subjects.

본 연구의 목적은 스마트폰 운영체제의 지배적 디자인을 결정하는 주요 요인이 무엇인지 제시하고 제시된 요인들과 사용만족 간의 논리적 인과관계를 검증하는데 있다. 이를 위해 지배적 디자인을 결정하는 스마트폰 운영체제의 주요 결정요인을 OS호환성, OS향상성, 사용자기반, 그리고 네트워크 효과 등으로 제시했다. 그리고 사용만족과의 논리적 인과관계를 실증분석했다. 연구결과, 스마트폰 운영체제의 OS호환성과 OS향상성은 사용기반 확대에 긍정적인 영향을 미치는 것으로 나타났다. 특히 OS향상성은 사용기반을 확대 시킬 뿐만 아니라 네트워크 효과를 강화시키는 원인으로 나타났다. 그리고 직접적으로 사용만족에도 긍정적인 영향을 미치는 것으로 나타났다. 연구결과는 그동안 실증연구가 이루어지지 않았던 운영체제의 지배적 디자인 결정과정에 대해 논리적 인과관계를 제시하여 학문적으로 뿐만 아니라 실무적으로도 크게 기여했다고 판단된다.

국내 기술의 발달로 인하여 다양한 항공기 발사 무장이 개발되고 있으며, 항공기-무장통합 인증에 대한 중요성 역시 높아지고 있다. 항공기-무장 통합 인증은 표준감항인증기준 (Standard ACC; standard airworthiness certification criteria)에서 제시하는 무장/장착물 통합 기준에 대한 적합성을 검증하여 안전 비행에 문제가 없다는 것을 증명하는 것으로, 무장 개발 후 항공기 통합 과정에서 요구되는 다양한 기준을 만족시켜야 함을 의미한다. 따라서 항공기의 요구사항을 무장 개발 과정에서 반영하여야 적합성 검증 단계에서 설계 변경 소요를 줄일 수 있다. 본 논문에서는 표준감항인증기준과 항공기-무장적합성 기준문서인 MIL-HDBK-1763, 그리고 순항유도무기 개발 프로세스간의 상관성을 분석하였다. 분석 결과 설계 초기 단계부터 공력 및 구조설계 분야에서 항공기 요구사항을 반영하여 개발을 진행하는 경우 항공기-무장 통합 인증 단계에서의 설계 변경 발생을 줄일 수 있다고 판단하였다.

The present research developed and empirically examined a theoretical model called a Mobile Channel Extension Model for consumer behavior toward mobile commerce. We proposed three antecedents: compatibility of, subjective norm regarding, and media influence regarding mobile use for communication purposes that influence the attitude toward the subjective norm and media influences of mobile use for shopping. These in turn positively influenced the consume's intention to use mobile devices for shopping. A Structural equation modeling analysis, using the data collected from a national online survey of 524 U. S. multichannel shoppers, confirmed the proposed model. The theoretical implications of these effects were discussed and managerial suggestions were made for both academicians and practitioners.
