  • This paper discusses the potential to upgrade the Thai innovation system by university-industry linkages. Our results are structured into three parts. First, the identification of potentials for university-industry linkages (UIL) within the Thai innovation system shows that the re is a wide gap between absorptive capacities of private companies and knowledge production of universities. Second, we present survey results for individual departments at Thai universities showing that UIL are mostly limited to consulting and technical services, hampered by mutual distrust, and maintained to receive an extra personal income. Third, case studies on four typical modes of UIL allow us to discuss various ways to upgrade the Thai IS by UIL in future.

  • This study empirically investigated the relationship between workers' safety behavior and safety leadership, trust in leader, workers' involvement, and safety knowledge in the enterprise, and analyzed the role of the factors to identify and analyze factors that enhance workers' safety behavior that contribute to the prevention of major accidents in the enterprise. When industrial accidents occur, companies have to bear huge loss costs due to direct costs of compensating the victims and indirect costs such as human loss, material loss, production loss, and time loss. Based on the results of previous studies, this study investigated the effects of managerial safety leadership and workers' trust in leader on safety behavior through the mediation of workers' involvement and safety knowledge among production, technical, and labor workers in the manufacturing industry. Statistical analysis was conducted on 271 manufacturing workers using SPSS and PLS. The results showed that safety leadership and trust in leader can lead to workers' involvement and have a positive effect on workers' safety knowledge acquisition, which can lead to workers' safety behavior.

  • This paper presents a variant type process planning system for machining of dies for auto-body production. Through the analysis of dies and their manufacturing processes, the authors categorized the press dies into 15 groups according to the similarity of machining features. After critically reviewing current manufacturing procedures, a standard process plan was defined for each group. The authors present MP3D the process planning system built on the standard process plan database, and show how they apply it at the die manufacturing plant of an automobile company. MP3D is expected to reduce major losses in machining such as reworking caused by mistakenly uncut features and eventually to help to accumulate the knowledge of operators. The operation sheet MP3D produces is also used in monitoring the progress of manufacturing of dies. This paper explains the whole development cycle of a process planning system from process analysis to application so that it can help readers to develop and apply a process planning system to their machine shops.

  • Scheduling jobs effectively under consideration of actual loads on machines is one of the most complicated tasks in production control. The complexity of the finite capacity scheduling often makes the conventional methods of industrial engineering fail. As an alternative, Knowledge-based approaches to job-shop scheduling have been evolved recently. This paper presents a blackboard- based scheduling expert system which combines knowledge-based scheduling with interactive scheduling. It is shown to be possible to generate the feasible schedule within a reasonable time. Flexible reaction management is also possible while keeping the changes in the generated schedule to the minimal and adjusting the schedule to tardy operations or working environmental changes. The system is equipped with a rule base with heuristics for handling conflicted event. A case study applying the implemented system is described.

  • In the manufacturing system, production-planning is very important in effective management for expensive production facilities and machineries. To enhance efficiency of Manufacturing Execution System(MES), a manufacturing system that reduces the difference between planning and execution, certain production-planning needs a dispatching rule that is properly designed for characteristic of work information and there should be a appropriate selection for the rule as well. Therefore, in this paper dispatching rule will be selected by several simulations based on characteristics of work information derived from process planning data. By constructing information that are from simulation into ontology, one of the knowledge-based-reasoning, production planning platform based on the selection of dispatching rule will be demonstrated. The platform has strength in its wider usage that is not limited to where it is applied. To demonstrate the platform, RacerPro and Prot$\acute{e}$g$\acute{e}$ are used in parts of ontology reasoning, and JAVA and FlexChart were applied for production-planning simulation.

  • Many processes in the industrial realm exhibit sstochastic and nonlinear behavior. Consequently, an intelligent system must be able to nonlinear production processes as well as probabilistic phenomena. In order for a knowledge based system to control a manufacturing processes as well as probabilistic phenomena. In order for a knowledge based system to control manufacturing process, an important capability is that of prediction : forecasting the future trajectory of a process as well as the consequences of the control action. This paper examines the robustness of data mining tools under varying levels of noise while predicting nonlinear processes, includinb chaotic behavior. The evaluated models include the perceptron neural network using backpropagation (BPN), the recurrent neural network (RNN) and case based reasoning (CBR). The concepts are crystallized through a case study in predicting a chaotic process in the presence of various patterns of noise.

  • A self-regulatory community fisheries management program in Korea is designed to enhance fisheries resources, to protect fishing grounds of self-regulatory communities, and to manage their fisheries resources by their own regulations and knowledge. This study explored an applicable ecosystem-based management plan based on the scientific investigation and analysis. This study suggested objectives, indicators and reference points of the ecosystem-based resource management system which are applicable to selfregulatory community fisheries. The objectives of the management system are to maintain sustainable fisheries production, to maintain optimum fishing intensity, to reduce by-catch, to conserve spawning ground and habitat, to maintain optimum habitat environment, to increase/maintain abundance of prey species, to increase/maintain stock biomass, and to conduct stock enhancement on the basis of scientific assessment. The improved methods for the assessment and management are introduced by demonstrating a self-regulatory fishery which targets on hen clam in Dong-li fishing village in Busan.

  • In this paper, a fed-batch cultivation process in recombinant Escherichia coli BL21(DE3) bacteria, for the production of human soluble catechol-O-methyltransferase (hSCOMT), is presented. For the first time, a straightforward model is applied in a recombinant hSCOMT expression system and distinguishes an initial cell growth phase from a protein production phase upon induction. Specifically, the kinetic model predicts biomass, substrate, and product concentrations in the culture over time and was identified from a series of fed-batch experiments designed by testing several feed profiles. The main advantage of this model is that its parameters can be identified more reliably from distinct fed-batch strategies, such as glycerol pulses and exponential followed by constant substrate additions. Interestingly, with the limited amount of data available, the proposed model accomplishes satisfactorily the experimental results obtained for the three state variables, and no exhaustive process knowledge is required. The comparison of the measurement data obtained in a validation experiment with the model predictions showed the great extrapolation capability of the model presented, which could provide new complementary information for the COMT production system.

  • Sound nutrition is the basic foundation for the health of a population. Proper nutrition education through the school system can actualize the building of sound nutrition being provided at school lunch programs along with nutrition education can have far reaching impact to the health of the whole nation. In Hong Kong, the recent change over from a half day to full day school program signaled the need for a school lunch program. However, there has been no organized effort so far in Hong Kong to provide such service. School lunches are being provided by caterers who are more concerned about profits than food safetly. Alarming rates of food poisoning occurring recently in Taiwan school has further accentuated the importance of fool safety. With the advent of centralized food production technologies, Dietirians can apply their nutrition knowledge and integrate with food production processes such that safe, healthy and nutritious mcals can be produced in large quantities in a cost-effective manner serving he needs of the school children. This paper introduces the centralized food production concept, using some of the cool chill production centers for school lunch programs in the United States as examples to discuss how new technologies and management system can be integrated to yield the best outcome in food quality and safety.
