Today, the most pivotal issue in the national research and development, and national scientific and technical policy is to overcome uncertainties in the environment of technology development. The social and economic environment around us is at restricted uncertainty (complex system) where order and disorder coexist. Furthermore, the environment of technology development is more complicated. In order to bring about creativity in practices of technology development, we need a paradigm shift towards a new framework for the construction of the national scientific and technical information infrastructure, which entails a shift to creativity, self-organization and dynamic capability. The paradigm shift will lead the present scientific and technical information infrastructure which centers on information sharing, to move towards one that enables information coherence through self-organization. Thus, it is expected that the new Web 3.0 will provide a client-flexible analysis information system that will make information coherence and feedback possible. Through this system, the policy for the construction of a new scientific and technical infrastructure will evolve, which will bring about co-evolution of individual's knowledge through sharing of self-organizaed knowhow.

The feasibility of using an adaptive resonance network (ART2) with unsupervised learning capability for too] wear detection in turning operations is investigated. Specifically, acoustic emission (AE) and cutting force signals were measured during machining, the multichannel AR coefficients of the two signals were calculated and then presented to the network to make a decision on tool wear. If the presented features are significantly different from previously learned patterns associated with a fresh tool, the network will recognize the difference and form a new category m worn tool. The experimental results show that tool wear can be effectively detected with or without minimum prior training using the self-organization property of the ART2 network.

Conventional radar antenna systems are susceptible to performance degradation caused by unwanted signals received via the antenna sidelobes and/or mainlobes. Adaptive array systems offer possible solution to this interference problem by automatically steering nulls to unwanted signals providing significant system performance improvement. Another important andvantage of the adaptive array is its self-optimization capability which uses the collective incoming noise data for the nulling purposes. This paper provides a tutorial introduction to adaptive arrays as well as some new development of recent research in this area. Optimum link between the antenna theory and signal processing has been sought by illustrating the gain patterns and output signal-to-noise ratio. Signal acqusition methods are shown including a new attempt of the use of spread-spectrum techniques in conjuction with array systems.

Objective: This study aimed to examine the effects of attachment and shared time between mother and child and self-esteem on subjective well-being in late childhood. Methods: A total of 329 fifth and sixth graders in elementary school (183 boys and 146 girls) participated in the study. They responded to questionnaires regarding attachment and shared time between mother and child and the self-esteem and subjective well-being of children. The data were analyzed using SEM. Results: Attachment and shared time between mother and child had an indirect effect through self-esteem as well as a direct effect on the subjective well-being of children. Children who formed secure attachments and spent more time with their mothers showed a higher level of subjective well-being. In addition, when children kept a good relationship with their mother quantitatively as well as qualitatively, they acknowledged their own capability and value positively, which led to higher subjective well-being. Conclusion: Findings emphasize that mother-child relationships play significant roles in predicting both the subjective well-being and self-esteem of children. The importance of self-esteem was identified in late childhood based on its relative influence on subjective well-being compared to mother-child relationships.

Energy-dissipative rocking (EDR) columns are a class of seismic mitigation device capable of dissipating seismic energy and preventing weak-story failure of moment resisting frames (MRFs). An EDR consists of two hinge-supported steel columns interconnected by steel dampers along its height. Under earthquakes, the input seismic energy can be dissipated by plastic energy of the steel dampers in the EDR column. However, the unrecoverable plastic deformation of steel dampers generally results in residual drifts in the structural system. This paper presents a proof-of-concept study on an innovative device, namely self-centring energy-dissipative rocking (SC-EDR) column, aiming at enabling self-centring capability of the EDR column by installing a set of shape memory alloy (SMA) tension braces. The working mechanism of the SC-EDR column is presented in detail, and the feasibility of the new device is carefully examined via experimental and numerical studies considering the parameters of the SMA bar diameter and the steel damper plate thickness. The seismic responses including load carrying capacities, stress distributions, base rocking behaviour, source of residual deformation, and energy dissipation are discussed in detail. A rational combination of the steel damper and the SMA tension braces can achieve excellent energy dissipation and self-centring performance.

Purpose: This study was a descriptive research to compare the teaching status of sex education and to examine differences in understanding teaching capability for sex education between school health educators and teachers working in elementary schools. Methods: A total of 307 subjects participated in the research including 182 school health educators and 125 teachers who gave sex education in elementary schools in Busan, Korea. Data were collected using a structured self-administered questionnaire and analyzed with frequency, t-test and $\chi^2$-test using SPSS WIN (version 10.0). Results: This study found that the school health educators carried out sex education more than the teachers, and perceived a higher level of teaching capability for sex education than the teachers when they were given four areas of sex education contents: physical and psychological development; sex and health; sex, culture and ethics; and understanding of personal relationships. In addition, a larger number of school health educators perceived that they were more qualified and more highly recognized as sex educators than the teachers. Conclusions: The results suggest that the school health educators must be more active as sex educators and that sex education should be adopted as a regular course and the school hours for sex education must be secured.
