Complementary and alternative medicine (CAM) practice is still popular among the Malaysian population nowadays although western or allopathic medicine is the first line of treatment. Dissatisfaction with health services and therapeutic effects of western medicine or preference for holistic, integrative approach in treatment are common reasons favouring the increasing popularity of CAM practices. The efforts toward integration of CAM and western medicine in Malaysia were rather slow and in a piece-meal fashion. Strategic efforts in strengthening government and self-regulation among practitioners, formalizing education, promoting research, and cultivating national and international networks are necessary to achieve an integrative system. Regulations to restrict the practice and sale of CAM products to licensed practitioners, strict and mandatory registration of the practitioners, inclusion of CAM in essential medicines list, and pricing regulations must be comprehensively discussed. Development of curriculum, offers of scholarship and incentives, promotion of courses and seminars for professionals is necessary to increase the numbers of CAM experts. Malaysia should follow the efforts of other countries on the production and documentation of local CAM data, allocation of funding, and establishment of research centres to assess the efficacy of potentially useful local products. Local and international collaboration in research and continuous education is important for exchange of knowledge and skills. In conclusion more coordinated efforts in regulation of CAM practice and products, formalizing CAM training and education would significantly move the process forward and allow the public to enjoy more health benefits from CAM practice in Malaysia.

An improved method of refolding recombinant human proinsulin from E. coli was presented. It was based on a two-stage stirred tank reactor in which denatured proinsulin-s-sulfonate was mixed instantaneously with a reaction buffer in the first stage reactor, and then fed to the second stage reactor. The mixture was stirred further for a total of 30h in the second stage reactor. In this system, unfavorable effects present due to the increase in reaction volume and protein concentration for protein refolding, which becomes significant in a large-scale operation, were avoided. Refolding yields of over 80% was obtained for achieving reaction volume of upto 50 l at protein concentration of 1 mg/ml. The optimum urea concentration was 1M. Refolding yield at the 1-1 reaction volume and protein concentration of 0.5mg/ml was increased about 2.5-fold, compared to that in a batch reactor. By increasing protein concentration in a two-stage refolding reaction, the cost for insulin production could be reduced, therefore, making this process economical.

In customer-oriented make-to-order manufacturing environments, the works of BOM changes due to the changes of product specification and engineering are closely connected with almost all departments such as sales, engineering, production, procurement, cost, after service, etc within an enterprise. So, the contents of BOM changes must be instantly reflected on the related works among the departments. To effectively process these complex works of BOM changes, types of changes on product specification and engineering and types of BOM changes linked with those must be systematically defined, classified and managed by information systems. Thus, it is necessary to introduce solutions such as BPM and SOA in order to efficiently deal with complex business processes like BOM change management. This paper proposes a methodology of constructing information systems based on BPM and SOA. The proposed methodology defines the relationship between processes of BPM for definition, execution, monitoring, etc of business processes and services of SOA for connection among information systems within an enterprise, and presents a scheme of practically applying BPM and SOA solutions to actual business works. To show an utilization of the proposed methodology, the prototype system for product BOM management is implemented in order to efficiently deal with the works of BOM changes due to the changes of product specification and engineering.

This paper presents the fabrication and performance evaluation of zinc oxide varistors for the arresters used for station system. ZnO varistors were fabricated with typical ceramic production methods and the structural and electrical characteristics were investigated. All varistors exhibited high density, which were in the range of $5.41{\sim}5.49g/cm^3$. In the electrical properties the reference voltage increased in the range of $4.410{\sim}5.250kV$ with increasing their thickness and the residual voltage exhibited the same trends as the reference voltage. In the long duration current impulse withstand test, E-2 and F-1 samples failed in the two and four shots, respectively, but E-1 and F-2 samples survived 18 shots during the test. Before and after this test, the variation ratio of residual voltage of E-1 and F-2 samples were -0.34% and 0.05%, respectively, which were in the acceptance range of 5%. According to the results of tests, it is thought that if the fabrication process such as insulating coating, sintering condition, and soldering method is improved, these ZnO varistors would be possible to apply to the station class arresters in the new future.

National Institute of Environmental Research (NIER) has developed the Korean Reach File (KRF) for scientific and systematic analysis of variables related to water quality, pollutant sources and aquatic ecosystems in consideration of steam reach networks. The KRF provides a new framework for data production, storage, management and analysis for water related variables in relation to spatial characteristics, connections, and topologies of stream reaches. However, the current version of KRF (ver.2) has limited applicability because its nodes include not only the stream points based on topological characteristics but also those based on water quality monitoring stations, which may undermine its generality. In this study, a new version of KRF (ver.3) was designed and established to overcome the weak point of version 2. The version 3 is a generalization of the old KRF graphic data and it integrates the attribute data while separating it from the graphic data to minimize additional work that is needed for data association and search. We tested the KRF (ver.3) on actual cases and convenience and adaptability for each application was verified. Further research should focus on developing a database link model and real-world applications that are targeted to process event data.

Currently, active research is being performed on printing of electronic devices such as RFID devices, flexible displays, solar cells, and e-paper. This technique has several advantages over existing technologies such as lithography and etching. In particular, RFID devices, flexible displays, solar cells, and e-paper require flexibility and a mass production system. Thus, attention is being focused on the roll-to-roll process. High quality should be guaranteed in the roll-to-roll printed electronics systems, and good thickness and roughness qualities must be ensured. Experimental design was applied to this problem to analyze the main effects and interaction effects of various factors. Matching technology between the nip roll characteristics and the quality of the print pattern in roll-to-roll printed electronics systems was proposed to improve the printing quality.

The ultimate purpose of game production is to make a game which satisfy game players and to sell maximum of products. In this paper, we suggest an assessment system model which can evaluate game satisfaction degree quantitatively, for preparing foundations that can make games which the suppliers and demanders of game business want. For it, we computed weight of constituent factors for game with AHP method based on survey, and quantified degree of satisfaction for genre of games to score. Also we analyzed affective factors for game satisfaction by SEM using LISREL software. In result, the greatest affective factor for game satisfaction is fun. For making the game with high degree of satisfaction, we propose that constructive investment and enough technology for fun are needed.

Customizing system is acting a main role for the character production system of MMORPG. However, since using the high degree of freedom in MMORPG, these characters are too individual and lack of awareness. We can describe each character's emotional characteristics and understand the correlation of characters more easily by adjusting design factors capable of cognitive decision to characters. Game character developer should consider seeking efficient character design process that is suitable to MMORPG game environment and users for proper character recognition and promoting character preferences. In addition, this research being extended on the article vol.13, no.3, "A Study on Cognitive and Preference of Games' Character" on Korean Society of Basic Design in June 2012 issue and this study is expected to have effectives as one method for the purpose of this research is to inquire and present what type of relation lies between recognition and preference of game characters of MMORPG.

Defects inspection of commodities are very important with those design and manufacturing process and essential to strengthen the competitiveness of those. If on-line automatic defects detection is performed without damaging to products, the production cost shall be curtailed through the reducing man-power, economical management of Q.C(Quality Control). In this paper, it is suggested three spatial filtering methods which can extract the necessary information in case of defects being on the surface of object like iron plate. In addition, the dependence of filtering characteristics on parameters such as the pitch and width of slits is analyzed and the surface defect detection system is constructed. Several experiments were carried out for determining the adequate spatial filtering method through comparing and analyzing effects of parameters like defect's size and shape, intensity of light, noise of coherent source and slit number.

The objective of the study is to propose diverse knitwear designs by expanding the scope of the use and application of knit fabric. The study looked into diversifying the knitwear designs by using different types of zippers and with the combination of the diversity given by the zipper used in attachable and detachable method and the traditional North European knit patterns. One way of contributing to the diversity of fashion design is to use the zipper, as it can be implemented as an attachable and detachable fastening system. Also, the combination of North European traditional knit patterns with knit fabric can create a new and unique knit styling. The content of the research focuses on the history and definition of North European traditional knitwear based on the analysis of theoretical background, types, and characteristics of the knit patterns. Case studies were observed to show the application of knit patterns. The methods of the study used are preceding research along with research, collection, analysis of data, information from Korean and foreign literature, and Internet websites. During knitwear production, the two types of zippers were used in combination with four traditional Northern European knitwear Aran, Fair Isle, Nordic, and Ropy. The knitting techniques applied in the process were cable fisherman (5GG, SES 124CS) and Tubular Jacquard (3GG, 7GG, SES 122CS) for knitting machinery, and the technique of whole garment for hand knitting.
