In early 1956, MSG (monosodium glutamate) had been produced by hydrolysis of the vegetable proteins in Korea. In accordance with development of fermentation technology mainly led by the Japanese scientists, its major production method has been changed to microbial fermentation since 1962. Meanwhile, 5'-ribonucleotides which are nucleic acid-related condiments have been produced by the enzymic hydrolysis of yeast RNA and/or the direct fermentation by Miwon Co. and Cheil sugar Co., respectively since 1977. At the technological viewpoints, Korean fermentation level seems relatively highly-reputated over the world in terms of production yield and unit-consumption level. For further progress of technology, our emphasis on this research area should be laid on both improvement of bacterial strain by means of modern biotechnology and process development through the immobilization and/or computerized control technics, etc.

Analog circuit design is comparatively more complex than its digital counterpart due to its nonlinearity and low level of abstraction. This study proposes a novel low-level hybrid of the sine-cosine algorithm (SCA) and modified grey-wolf optimization (mGWO) algorithm for machine learning-based design automation of CMOS analog circuits using an all-CMOS voltage reference circuit in 40-nm standard process. The optimization algorithm's efficiency is further tested using classical functions, showing that it outperforms other competing algorithms. The objective of the optimization is to minimize the variation and power usage, while satisfying all the design limitations. Through the interchange of scripts for information exchange between two environments, the SCA-mGWO algorithm is implemented and simultaneously simulated. The results show the robustness of analog circuit design generated using the SCA-mGWO algorithm, over various corners, resulting in a percentage variation of 0.85%. Monte Carlo analysis is also performed on the presented analog circuit for output voltage and percentage variation resulting in significantly low mean and standard deviation.

This paper employs datasets from the Enterprise Survey conducted by the World Bank to examine the relationship between four types of innovation defined by the Oslo Manual (OECD, 2005): product innovation, process innovation, marketing innovation, organization innovation, and the firm performance in the selected developing ASEAN economies. The main objective of this paper is to understand the characteristics of innovation activities at the firm level and how various innovation types affect firm performance. The empirical results from ASEAN manufacturing firms reveal that product innovation positively affects firms' performance, while non-technological innovations are negatively related to the performance of firms. The further employed quantile regression provides more insights into the roles of innovation types on different levels of firm performance: while product and process innovations actively contribute to the small and medium-size firms (below 25^th quantile and median), organizational and marketing innovations negatively affect them. Interestingly, the role of process innovation decreases when firm performance grows.

This study investigates the factors that facilitate or hinder people to use mobile payment, especially drawing upon the theoretical perspectives on individual's privacy protection motivation and perceived market condition. Survey data (n = 200) were collected through a web-based platform and used to test a theoretical model. The results show that one's privacy protection power is formed by various individual and technological factors (i.e., perceived data exposure, self-efficacy, and response efficacy), and in turn it determines his/her intention to use mobile payment. Moreover, the relationship between privacy protection power and mobile payment use is conditional on the perceived market control by the service provider - with a perception of the high level of provider's market control, one uses mobile payment regardless of his/her privacy protection power, while under the low level of provider's market control, the decision depends on the degree of privacy protection power. The findings would help our understanding of why some people are more susceptible to mobile payment and others are not.

Students often have tenacious physics misconceptions and many studies were conducted on engendering conceptual change. Correspondingly, there is much literature on alternative assessment and its role in student learning. This is a comparison study on using alternative assessments to improve common students' misconceptions in GCE Advanced Level Physics. This research also aims to affirm alternative assessment as a valid tool for learning and promote its use. This study involved two classes with 24 students each. For four weeks, electromagnetism was taught to students using the same classroom pedagogies but with different assignments. The control group completeda standard drill-and-practice assignment while the experimental group finished an alternative assessment. From the preliminary results, students who undertook the alternative assessment and the traditional assessment both improved, however, the treatment group did not perform statistically significantly better than the control group. The reasons will be discussed and commented and it is expected to have significant improvement on rectifying misconceptionsupon next batch of experimentation groups.

Debates about introducing nuclear submarines have been a main issue in Korea. The highest officials and the government has started to think seriously about the issue. Yet there were no certain decision to this issue or any agreements with US but it is still necessary to review about introducing nuclear submarines, the technologies and about the business. The reason for such issues are the highest officials of Korea to build nuclear submarine, nK's nuclear development and SLBM launching. ROKN's nuclear submarine's necessity will be to attack(capacity to revenge), defend(anti-SSBN Operation) and to respond against neighboring nation's threat(Russia, Japan, China). Among these nations, US, Russia (Soviet Union), Britain, France had built their submarines in a short term of time due to their industrial foundation regarding with nuclear propulsion submarines. However China and India have started their business without their industrial foundation prepared and took a long time to build their submarines. Current technology level of Korea have reached almost up to US, Russia, Britain and France when they first built their nuclear propulsion submarines since we have almost completed the business for the Changbogo-I,II and almost up to complete building the Changbogo-III which Korea have self designed/developed. Furthermore Korea have reached the level where we can self design large nuclear reactors and the integrated SMART reactor which we can call ourselves a nation with worldwide technologies. If introducing the nuclear submarine to the Korea gets decided, first of all we would have to review the technological problems and also introduce the foreign technologies when needed. The methods for the introduction will be developments after loans from the foreign, productions with technological cooperations, and individual production. The most significant thing will be that changes are continuous and new instances are keep showing up so that it is important to only have a simple reference to a current instances and have a review on every methods with many possibilities. Also developing all of the technologies for the nuclear propulsion submarines may be not possible and give financial damages so there may be a need to partially introduce foreign technologies. For the introduction of nuclear propulsion submarines, there must be a resolution of the international regulations together with the international/domestics resistances and the technological problems to work out for. Also there may be problem for the requirement fees to solve for and other tough problems to solve for. However nuclear submarines are powerful weapon system to risk everything above. This is an international/domestically a serious agenda. Therefore rather than having debates based on false facts, there must be a need to have an investigations and debates regarding the nation's benefits and national security.

무인항공기는 현대 전장 환경에서 감시정찰을 위한 필수요소이며, 전장의 복잡성과 불확실성이 증가함에 따라 그 중요성은 더욱 커지고 있다. 본 연구에서는 1982년부터 2014년까지 개발된 96대의 군용 무인항공기를 대상으로 비모수적이며 비통계적 기술예측 방법인 TFDEA를 이용한 기술예측을 실시하였다. 2001년에 최초로 소개된 이후 Inman 외(2006) 등은 TFDEA가 SOA 분석에서 회귀분석과 같은 전통적인 계량방법론보다 예측력이 우수함을 실증하였다. 본 연구에서는 무인항공기에 대한 기술예측 결과 연간 평균기술변화율이 4.06%로 향상되었으며, 개발된 대부분의 무인항공기는 첨단기술 프론티어(SOA) 보다 낮은 수준이었다. 이는 무인항공기를 개발하는 대부분의 국가가 기술적으로 중진국이고, 기술적 선진국인 북미와 유럽의 국가들이 세계 무인항공기 시장의 60% 이상을 장악하고 있다는 것에 기인한다고 볼 수 있다. 본 연구는 TFDEA의 적용분야를 미래체계로서 관심의 대상인 무인화 기술개발 분야로 확대하여 기술혁신의 특성을 분석함으로써 미래 무인항공기의 개발과 기술발전에 관한 기술예측의 기법으로서 적용가능성을 확인하였다. 특히 군의 작전요구성능과 연구개발관리에 필요한 정량적 지표를 설정하는데 활용할 수 있을 것으로 평가된다.
