Many advanced scholars and policy makers say that biotechnology is and will be the most important technology in 21th century. And biotechnology has a lots of character which are new and high tech industry, costing too much on early R&D stage and so on. One of them is that it can't be developed all seater by one single firm. So effective and efficient way to solve this generic problem is using the infrastructure which is given by government for flourishing the bio industry, especially, Knowledge infrastructure. The purpose of this study is to understand and give the information about which knowledge infrastructure affects biotechnology firms to obtain competitive advantage in technological improvement. To develop this object, I made 5 variables about infrastructure in biotechnology such as high-skilled researchers infrastructure, R&D policy infrastructure, industrialization infrastructure that supports the biotechnology industry, networking infrastructure between firms, universities, research centers, and finally bio-safety infrastructure. According to this study, to obtain technological competitive advantage for Korean bio firms, all main actors those are government, industry, university, research center they try to develop bio sector at the same time. After this cooperated effort, Korean bio firms and industry can get a international competitiveness in the global society which no one conquer the market.

The 10 species of marine green algae was collected from Jejudo(Island) in Korea. Methanolic and aqueous extracts were prepared and screened for inhibition activities against tumor cell growth. Of the tested samples, the sea staghorn (Codium fragile) aqueous extract (CFAE) showed the highest activity on CT-26 cell growth. Therefore, CFAE was selected for further experiments and the possibility to induce apoptosis by the CFAE was investigated. Flow cytometric analysis revealed that it dose-dependently increased apoptotic cells with hypodiploid DNA contents in CT-26 cell line. These results indicated that CFAE can suppress the growth of CT-26 cells through apoptosis. The CFAE decreased the protein expression of anti-apoptotic Bcl-xL and led to the activation of caspase-3 and -7. A crude polysaccharide was separated from CFAE and it mainly constituted with 61.2% galactose and 30.5% arabinose as analyzed by high performance liquid chromatography (HPLC).

우리나라는 GDP 대비 R&D투입율이 세계최고의 수준에 있으나 성과는 이에 비해 저조한 실정이다. 본 연구의 목적은 국내 바이오산업에서 전략적 자원과 공동체 공학(community engineering) 이 R&D 성과에 미치는 영향을 분석하는 것이다. 본 연구에서는 성과를 기술적 성과와 경제적 성과로 구분하였으며 조사 분석 결과 전략적 자원과 공동체 공학은 기술적 성과의 결정변수로 나타났으나 경제적 성과에 대해서는 전략적 자원만이 통계적으로 유의미한 영향을 미치는 것으로 나타났다. 또한 전략적 자원이 공동체 공학과 연구 성과 간의 관계에 대한 조절효과를 나타내지 못하는 것으로 나타났다.

This study examined the awareness, understanding, attitudes, and purchase intention regarding food labeling on bakery products in the context of health consciousness. The purpose of the study was to provide basic data for bakery product labeling, which has been insufficient to date, and to develop measures to expand the labeling system. The results of the study showed that higher subjective understanding and better attitude towards bakery food labeling can positively increase the purchase intention. We believe that the bakery industry needs to promote food labeling proactively, while also developing products addressing health concerns. This study is also valuable to academia because it provides insights into the relationship between the consumer's understanding of and attitudes towards nutritional information and purchase intention. In addition, it is beneficial to the bakery industry because it establishes marketing strategies that increase the purchase intent among both consumers with high health consciousness and those who infrequently purchase baked goods.

This paper describes a large area CMOS image sensor module Implementation using the precision align inspection program. This work is needed because wafer cutting system does not always have high precision. The program check more than 8 point of sensor edges and align sensors with moving table. The size of a $2{\times}1$ butted CMOS image sensor module which except for the size of PCB is $170mm{\times}170mm$. And the pixel size is $55{\mu}m{\times}55{\mu}m$ and the number of pixels is $3,072{\times}3,072$. The gap between the two CMOS image sensor module was arranged in less than one pixel size.

The human beings have Increased concern about Energy saving and alternative energy. The power demand has increased the growth of industry and the improvement of life We have to explore alternate energy sources and utilize effectively domestic resources. The lighting equipments developed Energy saving by using an electric ballast. The load installation should be promoted to rational power management, according to the network, intelligent, and high-function. Therefore, this paper has studied the method of energy saving and consulting.

Fashion marketing activity performed by social media influencers (SMIs) has grown exponentially in the past years. Research regarding their marketing power is often discussed in the context of sponsorship disclosure, in order to overcome obstacles of impending regulations that may endanger the authenticity SMIs are perceived to have compared to traditional marketing agents. Upon recent heterogeneous findings, a netnographic approach was taken to examine the actual sponsored posts of SMIs on Instagram. Based on two representative cases that received media coverage, a qualitative analysis of 1,058 comments on Instagram showed customer inspiration and informational social influence regardless of sponsorship disclosures present. Regarding customer inspiration, high frequency of comments including choice imitation intentions was observed. Under certain conditions, customer responses were focused on the SMI's expertise irrespective from the brand being endorsed. Findings show future implications from both an academic and industry-focused perspective for future potential of SMIs in fashion marketing.

To prevent oxidation of Mg melt, $SF_6$ gas has been generally used for Mg alloys during melting and casting as a cover gas. The use of $SF_6$ gas, however, will be restricted owing to its crucial impact on global warming. Non-$SF_6$ process during melting and casting in diecasting industry has been proved with Eco-Mg alloys by a simple addition of small amount of CaO into Mg alloys. This paper shows non-$SF_6$ diecasting procedures for 0.7wt% CaO added AZ91D Eco-Mg alloys. Cold-chamber diecasting was performed under $CO_2$ atmosphere without $SF_6$ gas. An increment of mechanical properties, especially strength and ductility of Eco-Mg alloys is, in part, due to high-quality melt, refined grain size and $Al_2Ca$ second phase strengthening. Microstructures and mechanical properties of 0.7wt% CaO added AZ91D Eco-Mg alloys are evaluated in comparison with those of conventional AZ91D Mg alloy.

This paper deals with the high efficiency drive of a vector controlled inverter fed induction motor system for electric vehicles. The loss equation is derived from the voltage equations in synchronously rotating reference frame. The ratio of the d-axis and q-axis component currents should be maintained constant to maximize the efficiency at a specified speed. Digital simulations are curried out and the results are compared with those of the conventional constant flux control.
