In [2] and [3], the Shinwon polynomial S$_{n}$(x) of order n is defined and studied in some details. In this paper we will define the general Shinwon polynomial S$_{n}$(a,x) and the Dickson polynomial D$_{n}$(a,x) of the second kind of order n which is a slightly changed form of the Dickson polynomial g$_{n}$(a,x), and show that D$_{n}$(a,x) is closely related to S$_{n}$(a,x).EX> n/(a,x).

Kenya’s Mobile Money and Financial Inclusion

Shinwon Kang,Hongkyun Bae 한국글로벌문화학회 2019 글로벌문화연구 Vol.10 No.1

21세기 많은 학자들은 가난한 사람들의 빈곤 퇴치를 위한 중요한 정책 중 하나로 금융포용을 제안하고 있다. 이는 경제적인 발전과 소득 불평등에 기여하는 중요한 수단으로 인식되기 때문에 금융 통합의 중요성이 강조되기 때문이다. 더불어 문화 포함의 중요성은 국제 사회에서 강조된다. 2009년 9월 G20 피츠버그 정상회담에서 국제 금융 개혁의 일환으로 재무 계획 의제가 채택되었다. 2010년 6월 토론토 정상 회담에서 9개의 "디지털 포용을 위한 혁신적인 원칙"(CGAP)이 채택되었다. 현재 아프리카의 모바일 머니서비스가 가장 빠르게 확산되고 활용되는 지역으로 부상하고 있으며, 케냐가 그 중 가장 눈에 띄는 사례이다. 케냐의 모바일 머니서비스 성공 사례는 저개발국가의 모바일 머니서비스의 성공에 그치는 것이 아니라 문화포용을 확산시키고 빈곤을 줄이기 때문에 중요한 것으로 평가된다. 본 고에서는 저개발국인 케냐의 모바일 금융서비스로 인한 문화포용 정도를 G20의 디지털 포용 원칙 8가지를 기반으로 분석했다. Currently, many scholars suggest "financial inclusion" as one of the important policies for the poverty alleviation of the poor. This is because the importance of cultural inclusion is emphasized because it is recognized as an important tool to contribute to economic development and income inequality. The importance of financial inclusion is emphasized in the international community. At the G20 Pittsburgh Summit in September 2009, the Financial Engagement agenda was adopted as part of the international financial reform. At the June 2010 Toronto Summit, nine "innovative financial inclusion principles" were adopted (CGAP). Now Africa mobile money service is emerging as the fastest spreading and utilizing area, and Kenya is the most prominent example of it. The success story of mobile money service in Kenya is not merely the success of mobile money service in underdeveloped countries, but it is evaluated as important because it spreads financial inclusion and reduces poverty. In this paper, We analyzed the extent of financial embarrassment due to mobile money service in Kenya, an underdeveloped country, based on the G20 "s 8 principles of digital financial inclusion.

A Study on the International Competitiveness of the Korean Culture Contents Industry

Shinwon Kang 한국글로벌문화학회 2023 글로벌문화연구 Vol.14 No.1

문화콘텐츠산업은 21세기의 고부가가치 신성장동력산업으로 전세계 주요 기업들이 콘텐츠 시장을 선점하기 위해 치열하게 경쟁하고 있는 분야이다. 이러한 콘텐츠 산업의 경쟁력을 높이기 위해서는 기업과 정부의 노력도 필요하지만 국가간, 글로벌 기업 간의 협력도 매우 중요하다. 최근 정보기술의 급속한 발전으로 문화콘텐츠 산업은 전 세계적으로 급격한 성장세를 보이고 있다. 그 결과 한국의 문화콘텐츠 산업은 국내 시장뿐 아니라, 해외 시장에서도 큰 인기를 얻으며 크게 성장했다. 특히 해외에서 한류 콘텐츠에 대한 수요가 늘어나면서 대한민국의 문화콘텐츠 산업의 성장 가능성이 크게 높아졌다. 본 논문에서는 문화콘텐츠 산업이란 무엇이며, 우리나라의 문화콘텐츠 산업의 현황, 정책, 그리고 국제협력에 대해 살펴보고, 글로벌 시장에서 경쟁력을 갖추기 위한 대책을 제시하는 한편, 제도적 지원과 기술개발의 필요성에 대해서도 논의하였다. The culture content industry is a high value-added new growth engine industry in the 21st century, and major companies around the world are fiercely competing to preoccupy the content market. Therefore, in order to increase the competitiveness of the culture content industry, efforts by companies and governments are important, but cooperation between countries and global companies is also very important. Recently, with the rapid development of information technology, the content industry is showing high growth all over the world. As a result, Korea’s content industry has grown significantly, gaining popularity not only in the domestic market but also in overseas markets. In particular, the growth potential of the domestic contents industry has greatly increased as the demand for Hallyu contents has increased overseas. In this paper, what is the content industry, examine the current status and growth potential of the domestic content industry, and suggest measures to be competitive in the international market. Also, the need for institutional support and technology development was discussed.

The Introduction and Limitations of Capitalist System in Vietnamese Market

Shinwon Kang,Hongkyun Bae 한국글로벌문화학회 2020 글로벌문화연구 Vol.11 No.1

베트남은 1986년 시장경제원리 도입을 골자로 하는 도이모이 정책을 추진한 이후 외국인 투자법 제정, 재정금융개혁 등의 자본주의 체제 도입을 통해 물가안정, 재정적자 축소, 외국인투자 증대 등 비교적 안정적인 경제성장을 지속하고 있다. 결론적으로 베트남은 지속적인 경제성장을 하고 있는 과정에서, 자본주의 체제 도입은 베트남의 경제성장에 실질적인 역할을 하고 있다. 특히 글로벌 공급사슬은 베트남의 경제성장에 중요한 역할을 하고 있는 것으로 분석되는데, 베트남 현지에 진출한 글로벌 기업의 수출이 빠르게 증가하며 시장은 확대되고 있는 반면, 베트남 로컬 기업의 대부분은 저부가가치의 제조 및 소매업 분야에 위치해 있어서 상대적으로 열위에 있다. 현재 베트남의 자본시장은 기존의 소수의 대기업이 주도하고 있으며, 같은 수준에서 경쟁할 수 있는 현지 기업의 성장이 부족하다. 장기적으로 베트남은 글로벌 경쟁에서의 자본주의 체제 도입의 한계를 극복하고, 글로벌 경제구도 하에 자국 산업의 지속적인 성장을 위하여 전향적인 기법의 적용이 요구되고 있는 시점이다. Vietnam pursued Doi Moi policy in 1986, which introduced the principle of market economy concept. Since then, the government has maintained relatively stable economic growth through stabilization of foreign investment laws and financial and financial reforms, such as stabilizing prices, reducing fiscal deficits, and increasing foreign investment. In conclusion, Vietnam continues to grow economically, and the advanced capitalist system plays a large role in Vietnam"s economic growth. In particular, global supply chains play an important role in Vietnam"s economic system. However, although markets expanded as exports of global firms entering Vietnam increased rapidly, most of Vietnam"s local firms are located in the low value-added manufacturing and retail sectors. In other words, under the current advanced capitalistic system in Vietnam is dominated by several large companies, and there is a lack of growth of local companies that can compete at the same level. Therefore, Vietnam needs to find various ways to overcome the limitations of capitalistic experience in the global supply chain and continue to grow.

A Study on the Cultural Industry in Cambodia: Acceptance and Expansion of Broadband

Shinwon Kang 한국글로벌문화학회 2021 글로벌문화연구 Vol.12 No.3

본 연구의 목적은 캄보디아의 광대역 인터넷의 현황과 주요 이슈를 살펴보고, 광대역 활용과 확산을 위한 시사점을 도출함에 있다. 인터넷의 경우, 정보 및 기술에 대한 접근성을 향상함으로써, 지속가능발전목표(Sustainable Development Goals)의 전 지구적 확산과 인류 보편의 공동목표를 달성하기 위한 다양한 문제를 효율적으로 달성하는데 기여하고 있다. 보다 구체적으로, 인터넷은 경제발전에 에 대한 중요한 역할을 위한 기제로 인식되어왔으며, 범용기술(general-purpose)로서의 ICT의 영향은 GDP 성장에 대한 직접적인 기여보다 파급효과(spillover effect) 또는 외부성(externalities)의 관점에서 더 큰 효과를 창출하는 것으로 알려져 있다. 세계은행(2018)는 인터넷은 경제성장을 촉진하고 생산성의 향상 및 빈곡감소에 중요한 역할을 한다고 언급하고 있다. 인터넷의 개발도상국 경제 및 사회발전에 매우 중요한 역 캄보디아는 광대역 인터넷의 활용에 따른 사회적 파급효과가 매우 낮으며, 이를 보완하고 사회발전을 도모하기 위한 시사점 도출이 요구된다. 따라서 광대역의 사회적 파급효과를 확대하기 위해서는 더 큰 광대역 연결에 입각한 개인, 기업, 정부 부분의 활용 확대에 초점을 맞추어야 할 것이다. This study aims to examine the current status and major issues of broadband Internet in Cambodia and draw implications for broadband utilization and spread. In the case of the Internet, improving access to information and technology is contributing to the global reach of the Sustainable Development Goals and efficiently achieving various problems to achieve the common goals of humanity. More specifically, the Internet has been recognized as a mechanism for playing an essential role in economic development. The impact of ICT as a general purpose has a spillover effect or externality rather than a direct contribution to GDP growth. It is known to create a more significant impact in terms of externalities. The World Bank (2018) states that the Internet plays an essential role in promoting economic growth, improving productivity, and reducing poverty. Therefore, the Internet is critical for economic and social development in developing countries. In Cambodia, the social ripple effect of broadband Internet use is shallow. Therefore, to expand the social ripple effect of broadband, it is necessary to focus on increasing individuals, businesses, and governments based on more significant broadband connections.

강신원(Shinwon Kang),이중만(Jung Mann Lee) 한국데이타베이스학회 2016 Journal of information technology applications & m Vol.23 No.2

Mobile financial services with incorporated into IT are actively introduced and being operated worldwide. Meanwhile, a relationship setting of industrial capital and financial capital has a close connection with development process of the financial markets and the economic development. If the relationship setting of industrial capital and financial capital are right, it will be good opportunity to ensure economic development, positive economic effect and global competitiveness of the financial industry as other developed countries. In order to expand the positive effects of these mobile financial services, a ICT companies, etc. should ease regulations to allow entry to the mobile financial services market. That is, the separation of banking and commerce should be abolished.

Antimicrobial Susceptibility Trends and Risk Factors for Antimicrobial Resistance in Pseudomonas aeruginosa Bacteremia: 12-Year Experience in a Tertiary Hospital in Korea

Kang Jin Suk,Moon Chisook,문석준,Lee Jeong Eun,Lee Soon Ok,Lee Shinwon,Lee Sun Hee 대한의학회 2021 Journal of Korean medical science Vol.36 No.43

Background: Infections caused by multidrug-resistant Pseudomonas aeruginosa (MDRPA) have been on the rise worldwide, and delayed active antimicrobial therapy is associated with high mortality. However, few studies have evaluated increases in P. aeruginosa infections with antimicrobial resistance and risk factors for such antimicrobial resistance in Korea. Here, we analyzed changes in antimicrobial susceptibility associated with P. aeruginosa bacteremia and identified risk factors of antimicrobial resistance. Methods: The medical records of patients with P. aeruginosa bacteremia who were admitted to a tertiary hospital between January 2009 and October 2020 were retrospectively reviewed. Antibiotic resistance rates were compared among the time periods of 2009–2012, 2013–2016, and 2017–2020 and between the intensive care unit (ICU) and non-ICU setting. Empirical antimicrobial therapy was considered concordant, if the organism was susceptible to antibiotics in vitro, and discordant, if resistant. Results: During the study period, 295 patients with P. aeruginosa bacteremia were identified. The hepatobiliary tract (26.8%) was the most common primary site of infection. The rates of carbapenem-resistant P. aeruginosa (CRPA), MDRPA, and extensively drug-resistant P. aeruginosa (XDRPA) were 24.7%, 35.9%, and 15.9%, respectively. XDRPA showed an increasing trend, and CRPA, MDRPA, and XDRPA were also gradually increasing in non-ICU setting. Previous exposure to fluoroquinolones and glycopeptides and urinary tract infection were independent risk factors associated with CRPA, MDRPA, and XDRPA. Previous exposure to carbapenems was an independent risk factor of CRPA. CRPA, MDRPA, and XDRPA were associated with discordant empirical antimicrobial therapy. Conclusion: The identification of risk factors for antimicrobial resistance and analysis of antimicrobial susceptibility might be important for concordant empirical antimicrobial therapy in patients with P. aeruginosa bacteremia.

Trends in Malignancies among Korean Patients Infected with Human Immunodeficiency Virus in the Highly Active Antiretroviral Therapy Era

Lee, Shinwon,Lee, Sun Hee,Lee, Jeong Eun,Kang, Jin Suk,Lee, Seung Geun,Chung, Joo Seop,Kwak, Ihm Soo KOREAN ACADEMY OF MEDICAL SCIENCE 2017 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.32 No.9

<P>Since the introduction of highly active antiretroviral therapy, the life span of people with human immunodeficiency virus (HIV) or AIDS (PWHA) has been extended significantly. Therefore, the importance of non-AIDS-defining cancers (NADCs), as well as AIDS-defining cancers (ADCs) has increased. There is little information concerning the epidemiology of malignancies in PWHA in Korea. A descriptive epidemiologic study was conducted at a tertiary care hospital in Korea. PWHA who visited Pusan National University Hospital from January 2000 to October 2014 were included. Demographics and clinical data were obtained from the medical records and analyzed. A total of 950 PWHA were observed for 4,439.71 person-years. Forty-eight episodes (5.05%) of cancers were diagnosed in 47 patients. Mean age of the enrolled patients was 40.66 ± 12.15 years and 88% were male. Among the 48 cancer episodes, 20 (42%) were ADCs and 28 were NADCs. The most common ADCs was non-Hodgkin's lymphoma (53.6%), followed by Kaposi's sarcoma (17.9%). The most common NADCs were lung cancer (25%) and hepatocellular carcinoma (25%). The overall incidence of total cancers, ADCs, and NADCs was 10.8 (95% confidence interval [CI], 8.0–14.3), 4.5 (95% CI, 2.8–7.0), and 6.3 (95% CI, 4.2–9.1)/1,000 person-years, respectively. NADCs accounted for 12/15 (80%) of cancers among PWHA with good adherence to care. The 5-year survival rate of PWHA and NADC was 26.3%. NADCs have become the main type of malignancy among Korean PWHA with good adherence to care. Effective strategies to improve screening of NADCs among PWHA are required in Korea.</P>
