Fields of domestic construction supervision are divided into architecture, electricity, information and communication and fire by the individual laws. Between each supervision are lack of relationship. So it bring about performance degradation, supervision fee increasing and dispute. The purpose of this basic research is to suggest the integration method of each supervision.

In this paper, we propose new algorithm of speaker recognition which identifies the speaker using the information obtained by the intensive speech feature analysis such as pitch, intensity, duration, and formant, which are crucial parameters of individual voice, for candidates of high percentage of wrong recognition in the existing speaker recognition algorithm. For testing the power of discrimination of individual parameter, DTW (Dynamic Time Warping) is used. We newly set the range of threshold which affects the power of discrimination in speech verification such that the candidates in the new range of threshold are finally discriminated in the next stage of sound parameter analysis. In the speaker verification test by using voice DB which consists of secret words of 25 males and 25 females of 8 kHz 16 bit, the algorithm we propose shows about 1% of performance improvement to the existing algorithm.

The effects of three minor elements, S, Ce and Bi, on the inoculation ability and fading behavior of 1.0 wt%Ba-Fe-Si were investigated through thermal analysis. The performance of 1.0 wt%Ba-Fe-Si inoculant was better and more consistant at the high temperature range of $1,450{\sim}1,500^{\circ}C$ than that of low one of $1,300{\sim}1,400^{\circ}C$. That was improved with individual addition of three minor elements. The optimum amount of addition was 1.0% of the weight of inoculant added, respectively. That was improved also by the simultaneous addition of two or three kinds of minor elements. Even though worse with the addition of two kinds of them simultaneously than with individual addition, that was improved with the simultaneous addition of all three kinds over that with the individual one.

This paper describes Sexual Reproduction Genetic Algorithm(SRGA) for function optimization. In SRGA, each individual utilize a diploid chromosome structure. Sex cells(gametes) are produced through artificial meiosis in which crossover and mutation occur. The proposed method has two selection operators, one, individual selection which selects the individual to fertilize, and the other, gamete selection which makes zygote for offspring production. We consider the effects of multi-selection and diploidy on search performance. SRGA improves local and global search(exploitation and exploration) and show optimum tracking performance in nonstationary environments. Gray coding is incorporated to transforming the search space and Genic uniform distribution method is proposed to alleviate the problem of premature convergence.

Most aircraft accidents are attributed to crew error, but traditional training programs focus on individual training and evaluation. So, FAA developed innovative training and qualification programs that incorporate the most recent advances in training methods and techniques. AQP(Advanced Qualification Program) is focus on crew and individual performance in both training and evaluation. The primary goal of AQP is to achieve the highest possible standard of individual and crew performance. Nowaday, a lot of Airlines of US and Europe are managing aircrew qualification with AQP or ATQP. This paper proposed government's organization, documents, personnel and education to apply AQP to Korea, as well as domestic airlines available application of AQP.

This study investigates the effects of individual and group level factors on the use of GSS (Group Support System) and task performance from GSS use. GSS facilitates the group work, so that GSS adoption is not necessarily influenced only by individual perceptions on information systems as TAM insists. Adaptive Structuration. Theory (AST) joins with TAM in our study to explain the adoption and success from GSS use. AST contends that the success of IS is not necessarily the technical fit between tasks and technology, instead the political outcome among user socializations. We found that collected data from 303 individual IT staffs in a national bank. Our results demonstrate that traditional theories on TAM (Technology Acceptance Model) need to be refined, when considering the TTF(task-technology fit). TTF render high influences on PU(perceived usefulness). PEU(perceived ease of use) and FOA(faithfulness on appropriation). And FOA influences highly on our dependent variable. Implications and directions for future research are discussed.

Most of the existing studies on intellectual capital have focused on categorizing and measuring intellectual capital. In this study, the components of intellectual capital have been termed individual capital, organization capital, and relation capital, and the relations among these components as well their effects on other components have been examined. Thus, the indices of intellectual capital have been measured, hypotheses formed, and data collected from 62 knowledge-based companies. The results confirm some of the hypotheses. In all the companies that replied, individual capital was positively related to organization capital and organization capital was positively related to relation capital. The hypothesis that relation capital is positively related to performance, therefore, could be accepted. In the knowledge-based companies, the results were similar to the previous ones, but individual capital was not related to relation capital.

The main purpose of this study is to understand how cognitive factors influence the way people interact with information/information systems, by conducting comprehensive and in-depth literature reviews and a theoretical synthesis of related research. Adaptive systems have been built around an individual user's characteristics, such as interests, preferences, knowledge and goals. Individual differences in the ability to use new information and communication technology have been an important issue in all fields. Performance differences in utilizing new information and communication technology are sufficiently predictable that we can begin to coordinate them. Therefore, it is necessary to understand cognitive mechanisms to explain differences between individuals as well as the levels of performance. The theoretical synthesis from this study can be applied to design intelligent (i.e., human friendly) systems in our everyday lives. Further research should explore optimization design for user, by integrating user's individual traits (such as emotion and intent) and system modules to improve the interactions of human-system in data-driven environments.

The purpose of this study is to prove the hypothesis that the learning transfer climate, such as individual learning self-efficacy and corporate innovative knowledge transfer, will play a mediating role in the relationship between design competency strengthening education and individual performance considering the designer's characteristics. This is meaningful in expanding the meaning of design education and training by quantitatively analyzing the learning transfer climate that affects learning self-efficacy and organizational culture according to the characteristics of designers, unlike existing studies that simply investigate the satisfaction of education. Specifically, this study set up seven hypotheses, and as a result, it was found that design capacity building education for designers, learning self-efficacy, and learning transfer climate of companies had a significant effect on individual performance.

This study is to constructs the model by the relationship between the most important ones of TPM's step activities which are derived from the result of AHP analysis and the management performance. And it is to analyze whether step activities have impact on corporate performance through the mediating variable from a convergence point. Also it is to choose four step activities - irrational field and loss improvement, preparation and system establishment for the basic conditions of 5S, initial cleaning, loss analysis of facility efficiency - as independent variables, and to analyze the effect of TPM activity level as mediating variable on management performance as dependent variable. According to the analysis, four step activities don't have direct effect on corporate performance but TPM activity level as mediating variable has a full-mediated effect on corporate performance. That is, TPM activity level has been shown to play a role as mediating variable. Therefore, higher recognition of confidence in facility, awareness of self-development and definitive management of individual work shows TPM activity can contribute to corporate performance successfully.
