  • Multimodal interfaces are recognition-based technologies that interpret and encode hand gestures, eye-gaze, movement pattern, speech, physical location and other natural human behaviors. Modality is the type of communication channel used for interaction. It also covers the way an idea is expressed or perceived, or the manner in which an action is performed. Multimodal Interfaces are the technologies that constitute multimodal interaction processes which occur consciously or unconsciously while communicating between human and computer. So input/output forms of multimodal interfaces assume different aspects from existing ones. Moreover, different people show different cognitive styles and individual preferences play a role in the selection of one input mode over another. Therefore to develop an effective design of multimodal user interfaces, input/output structure need to be formulated through the research of human cognition. This paper analyzes the characteristics of each human modality and suggests combination types of modalities, dual-coding for formulating multimodal interaction. Then it designs multimodal language and input synchronization method according to the granularity of input synchronization. To effectively guide the development of next-generation multimodal interfaces, substantially cognitive modeling will be needed to understand the temporal and semantic relations between different modalities, their joint functionality, and their overall potential for supporting computation in different forms. This paper is expected that it can show multimodal interface designers how to organize and integrate human input modalities while interacting with multimodal interfaces.

  • Vaccines are the most effective and cost-efficient method for preventing diseases caused by infectious pathogens. Despite the great success of vaccines, development of safe and strong vaccines is still required for emerging new pathogens, re-emerging old pathogens, and in order to improve the inadequate protection conferred by existing vaccines. One of the most important strategies for the development of effective new vaccines is the selection and usage of a suitable adjuvant. Immunologic adjuvants are essential for enhancing vaccine potency by improvement of the humoral and/or cell-mediated immune response to vaccine antigens. Thus, formulation of vaccines with appropriate adjuvants is an attractive approach towards eliciting protective and long-lasting immunity in humans. However, only a limited number of adjuvants is licensed for human vaccines due to concerns about safety and toxicity. We summarize current knowledge about the potential benefits of adjuvants, the characteristics of adjuvants and the mechanisms of adjuvants in human vaccines. Adjuvants have diverse modes of action and should be selected for use on the basis of the type of immune response that is desired for a particular vaccine. Better understanding of current adjuvants will help exploring new adjuvant formulations and facilitate rational design of vaccines against infectious diseases.

  • Under the circumstance of increasing international trade volumes and limitation of customs human resources, it is necessary to shift the customs' revenue collection activities and audit method from a transaction-based approach to an account-based approach. Thus, in 1997, U.S. Customs services established the Account Management Program. The Account Management Program is designed to increase importer compliance and improve customer service through one-on-one interaction with business entities and a designated Customs representative(Account Manager). The Account Management Program is a comprehensive process that includes the following stages and activities ; selection of a potential Account, establishment of the Account, management of the Account. In 2009, Korea Customs service introduced and executed the Account Management Program. But owing to its early stages, Korea Customs service does not suggest effective direction of development of the AM program. So I can propose the following improvements of the Account Management Program in Korea. Firstly, the Account Managers have to be assigned more traders than AEOs(Authorized Economic Operators). Secondly, it is necessary that Customs service appoints part-time port Account Managers to help more traders to improve customs compliance. Thirdly, thought should be given as to Account can be expanded to encompass both small and medium enterprises(SME) by providing customs brokers managing their customs business on the behalf of the SME with the Account Managers. Lastly, Customs service has to establish performance measures and action plan for the Account Management Program.

  • It is well known that acupuncture is effective for treatment of gastric disease in human. For years, we have been utilizing a electro-acupuncture(EA) in attempt to manage gastric symptoms. However, the data on clinical effectiveness is conflicting and the action of acupoints is unclear. The purpose of this study was to investigate the effects of manual and electro acupuncture(EA) at acupoints of ST 36 and GB 34 on the serum gastrin level by radioimmunoassay in rats. All of acupuncture treatment was applied to the acupoints for 30 min during 3 days. Manual acupuncture with both acupoints resulted in increased gastrin serum level when compare to control group treated with only anesthesia. Either high (100 Hz) and low (2 Hz) frequency EA at ST 36 decreased gastrin serum level compared with control group, but EA at GB 34 conversely increased. In EA with device was designed stimulating only acupoint(New EA), either low frequency on ST 36 and high frequency on GB 34 unusually increased gastrin serum level compared to control group. The results of this experiment suggest that many factors, such as the selection of acupoints, the manipulation and the specification of acupuncture device, are capable of affecting acupuncture effects.

  • Laser surface polishing is a polishing method for improving surface roughness using an integrated laser beam. Using a laser for surface polishing can improve the surface condition without physical contact or chemical action. Laser polishing has mainly been used to polish the surface of diamond or optical articles, such as lenses and glasses. Recently, diverse studies on laser polishing for metals have been conducted. The analytic study of laser surface polishing has been conducted with experimental trials for comparison, so that the proper conditions for laser polishing can be recommended. In this study, laser surface polishing was simulated in order to predict the heat-affected zone on the die steel depending on the power of the pulsed laser. The simulated results were verified by comparing them to those of the experimental trials. Through this study, therefore, the application of FEM to the selection of appropriate laser conditions could be possible.

  • Application of lactic acid bacteria in the markets are divided into four categories: dairy industry, health food industry, animal feed industry and pharmaceutical industries. Recently, Lactobacillus acidophilus have been used in the food industry and have obtained great attention as key cultures for health benefit. Since commercial application of L. acidophilus has become a common practice, characterization of these cultures were made. Futhermore, the strains selected should produce a final dairy product possessing good taste and acceptable body and texture, a selection step that cannot be achieved unless the product is actually manufactured. Conjugated linoleic acid (CLA) have been recognized as antioxidants, cancer inhibitors, cholesterol depressing agents, and growth promoting factors. Food products from ruminants, particularly dairy products, are the major dietary source of CLA f3r humans. The CLA content in yogurt or cheese can be increased by action of the starter cultures. The finding of the production of CLA by food starter culture opens interesting perspectives far the future in producing fermented products enriched in CLA.

  • An efficient method of selecting an antagonistic strain for use as a biological control agent strain was developed. In this improved method, the surface tension reduction potential of an isolate was included in the 'decision factor,' in addition to two other factors; the growth rate and pathogen inhibition. By using a statistically designed method, an isolate from the soil was selected and identified as Bacillus sp. GB 16. In the pot test, this strain showed the best performance among the isolated strains. The lowest disease incidence rate and fastest seed growth were observed when the Bacillus sp. GB 16 was used. The action of the surface tension reducing component was assumed to enhance the wetting, spreading, and residing of the antagonistic strain in the rhizosphere. This result showed that the improved selection method was quite effective in selecting the best antagonistic strain for the biological control of soilborne infectious plant pathogens.
