모기 살충성 내독소를 생산하는 Bacillus thuringiensis subsp. guiyangiensis 21-2균주(H serotype 43)의 특성
김광현,김위종 동의대학교 기초과학연구소 2000 基礎科學硏究論文集 Vol.10 No.1
To prevent appearance of resistant mosquitoes against δ-endotoxin of Bacillus thuringiensis subsp. israelensis (Bu) in field, a mosquitocidal Bacillus thuringiensis strain 21-2(Bt 21-2) producing a new type of δ-endotoxin was isolated. The strain Bt 21-2 belongs to H serotype43. B. thuringiensis subsp. guiyangiensis(Btg). The δ-endotoxins from the strain Bt 21-2 and the strain Bti were a cuboid shape morphologically, but the δ-endotoxin from the type strain Btg was a bipyramidal shape on phase contrast microscope. The δ-endotoxin of the strain Bt 21-2 was composed of 150.90 and 70 KDa proteins on SDS-PAGE, and the antigenicity of δ-endotoxin of the strain Bt 21-2 was different from that of the strain Bti on immunoblot. The δ-endotoxin gene of the strain Bt 21-2 was not amplified with specific primers of δ-endotoxin gene (cry4A and cry4B) of the strain Bti on PCR.

‘빈테크’의 출현 이유와 그에 따른 문제점에 대한 연구
김광현,김태은 한국지식정보기술학회 2020 한국지식정보기술학회 논문지 Vol.15 No.2
This paper outlined the concept of 'Vintech,' a new financial method that emerged in the wake of the economic downturn. The study was conducted to address social phenomena by paying attention to consumer spending patterns. According to the report, "AppTech," which makes pocket money from original fintech, has met social phenomena and has become a means for poor young people to take new allowances. The combination of technology and social phenomena has led to the emergence of "vintech," and as science and technology develops, its kind and methods are expected to be endless. The ashtray has already led to a variety of vintech types, joining many companies. We believe that each type of problem exists, but the solutions presented will be realistic and manageable. In addition, although Vintech originated in Japan, Japan's fintech service is a market of opportunity for Korean companies with advanced services because of its slower development compared to other advanced countries. Using the growth power of the local fintech market as a springboard, one can expect to develop technologies through convergence with various information industry sectors such as AI, big data and blockchain, and also think about the future re-tech method.

In this study, domestic application companies are saturated, and foreign application companies such as Utube, Twitter, Hotelscombine, and Twitch TV are penetrating into the domestic market. On the other hand, domestic companies are not focusing on quality improvement and new business, but focusing on marketing and advertising. One way to overcome this is to pioneer new overseas markets. In developed countries such as the US, Japan, and Europe, there are many market demands, but there are many competitors. Smartphone performance is rising sharply in Southeast Asia in 2019, but the number of applications in use is less than half of those in developed countries on average. Philippine application market is expected to be higher than competitors in other Southeast Asian markets but because it speaks English, it is not difficult to enter the Philippine application market. The study also revealed why domestic application companies should enter overseas markets to find new customers. This study analyzed the cases of domestic application companies failing and successfully entering overseas markets. In addition, by analyzing the infrastructure and utilization of the Philippines in terms of the app industry, we propose strategies for domestic companies to enter the Philippines application market more easily and safely.

This paper describes the new elements of big data that have emerged in the modern era and then states the importance of big data through utilization and examples. With customers' needs and value diversified and rapidly changing, companies are increasingly required to analyze information and data needed by businesses through real-time vast amounts of data generated by them and use it throughout their business operations, and with the development of IT technology and the 4th industrial revolution, the era of big data has begun in which companies acquire and analyze information and obtain information needed by companies at a cost that is easier and less than before. In the modern society, companies have transformed into an era where they cannot survive without the existence of data, and each company continues its efforts to develop through big data, gaining customers' attention and increasing loyal customers through its own programs and marketing strategies to meet each discipline. For example, Amazon's Anticipate sipping, Amazon's Web service, the Mystique System of the Ritz-Carlton Hotel, and Wal-Mart Lab, which highlights how and the importance of using big data worldwide, should be studied to present the corporate strategies and directions that Korean companies with weaknesses should perform in the use of big data, and make efforts to enhance competitiveness of each company and survive in corporate competition through cooperation with the government.

사람들의 행동양식은 커뮤니케이션과 의사결정을 하게하고 관리자들의 리드하는 방식, 갈등과 스트레스를 관리하는 분야에 영향을 준다. 그리고 이것들은 문화적으로 통제하기도 하고 조직의 궁극적 효과에 영향을 준다. 기술이 조직의 의사소통을 변화시켰듯이 의사결정도 변화시킨다. 또한 원격의사소통을 제공하는 직원들에게 발생하는 스트레스와 대항하게 도울 수 있다. 본 연구에서는 전자상거래 조직 내에서 필수적인 요소인 팀, 커뮤니케이션, 의사결정, 리더십, 스트레스에 대하여 탐구한다. 의사결정이 합법적이라도 윤리적인 면에서 기업의 사회적 책임을 지적한다.
