The dream of futurists andtechnologists is to build complex, multifunctional machines so small that theycan only be seen with the aid of a microscope. The unprecedented technologyadvancements in miniaturizing integrated circuits on semiconductors, and theresulting plethora of sophisticated, low cost electronic devices demonstratethe impact that micro/nano scale engineering can have when applied only to thearea of electrical and computer engineering. Emerging research efforts indeveloping organic and inorganic nano materials together with using micro/nanofabrication techniques for implementing integrated multifunctional devices hopeto yield similar revolutions in other engineering fields. By cross linking theindividual engineering fields through micro/nano technology, various organicand inorganic materials and miniaturized system devices can be developed thatwill have future impacts in the IT and life science applications. Yet to buildthe complex micromachines and nanomachine of the future, engineering will needto develop the technology capable of seamlessly integrating these materials andsubsystems together at the micro and nano scales. The micromachines of thefuture will be “integrated nanosystems,” complex devices requiring the integration of multiple materials,phenomena, technologies, and functions at the same platform. To develop thistechnology will require great efforts in materials science and engineering, infundamental and applied sciences. In this talk, we will first discuss thenature of micro and nanotechnology research for IT and life sciences, and thenintroduce selected current activities in micro and nanotechnology research fororganic and inorganic materials and devices. The newly developed micro/nanofabrication processes and devices, combined with in-depth scientificunderstandings of materials, can lead to rapid development of next generationsystems for applications in IT and life sciences.

This study examined the relationship between maternal attitudes toward children's expressiveness, children's emotional intelligence and problem behaviors. The question as to whether emotional intelligence mediated the relationship between maternal attitudes and problem behaviors was also explored. A sample of 307 preschool children were used as subjects. Mothers rated their levels of acceptance toward their children's emotions, while teachers reported on the children's emotional abilities and behavioral problems. The data were analyzed by means of regression analyses. Our results indicated that mothers' controlling attitudes were associated with low levels of worry-anxiety. Additionally, it was found that children with high emotional intelligence showed low levels of worry-anxiety, hostility-aggression, and hyperactivity-inattention. While multiple factors of emotional intelligence had differential impacts, the self-control factor was the most powerful predictor for all the problem behaviors. It was further found that a mother's receptive attitude was related to higher levels of self-awareness in children. Instead of the significant mediating effect of emotional intelligence, it was revealed that emotional intelligence had greater effects upon problem behaviors than maternal attitudes toward children's expressiveness.

This study aims to empirically verify the impacts of job autonomy, job feedback and job manualization on the job satisfaction of the non-regular employees in a public corporation. For the empirical analysis, 163 non-regular employees(valid respondents) have been surveyed who are working in a public corporation. And the multiple regression analysis was used to statistically test the research hypotheses. The independent variables are 'job autonomy', 'job feedback', and 'job manualization'. The dependent variable is 'job satisfaction'. The results are as follows. The effects of 'job autonomy → job satisfaction(β=0.182, t=2.664, p<0.01)', 'job feedback → job satisfaction(β=0.208, t=2.927, p<0.01)' and 'job manualization → job satisfaction(β=0.397, t=5.785, p<0.01)' are all shown positive. Therefore, all the proposed hypotheses are accepted. From this result, we can get some lessons for the organizational management especially for the non-regular employees' job satisfaction. If you recognize that the non-regular workers are also valuable human resources for the company, it can be expected that strengthening the internal motivation of the employees through job enrichment such as autonomy, feedback, and manualization can positively influence the effectiveness of the organization.

Recently, as the importance placed on the design phase of system development has increased, the use of diagrams to design the overall system before implementing the actual program code has seen a proportionate increase. This study focuses on the diverse diagrams depicting organizational processes when integrating multiple processes of individual organizations to form an Inter-Organizational System(IOS). In this study, we attempt to identify the critical representation features of process diagrams that enable the effective integration of Inter-Organizational processes. In particular, the effect of the mapping relationship between the representation features of different diagrams to be integrated was tested empirically in a laboratory setting. The experimental task consisted of integrating the processes of two organization based upon the given process diagrams. Actual business processes were selected from real world cases and process diagrams were formulated based upon existing object-oriented notation. An analysis of the errors committed by the subjects during the integration process indicated that the mapping relationship between the diagram features representing the respective organizational processes had a significant impact upon the final integration outcome. Based upon these results, the present study provides a guideline for process diagrams that are crucial to effective Inter-Organizational process implementation and maintenance.

The purpose of this study was to investigate the effects of mass media and personal factors on attitudes towards plastic surgery and plastic surgery behavior. For this study the personal factors included concern for appearance, self-esteem, and body satisfaction. Subjects were 472 college students in Ulsan. The results showed that favorable attitudes towards plastic surgery were a little higher than the median, meaning that the respondents had a slightly positive attitude towards plastic surgery, and only 20% of the respondents had had an experience with plastic surgery. A multiple regression analysis was computed and indicated that a more positive attitudes towards plastic surgery was related to high levels of concern for appearance, more time watching TV, a higher household income, and being a female student, in terms of gender. The results of logit analysis indicated that a more positive attitude towards plastic surgery and being a female student related to a higher probability of having had plastic surgery.
