Objectives : We conducted this study to examine the association between serum GGT levels within the normal range and the risk factors of cardiovascular diseases Methods : We examined the cross-sectional association between serum GGT and the systolic and diastolic blood pressure, fasting blood glucose, total cholesterol, triglyceride, high density lipoprotein cholesterol (HDLcholesterol), and uric acid among 975 subjects that participated in the health examination of a university hospital located in Daegu city. All the patients' GGT levels were within the normal range. Results : After adjustment were made for age, body mass index (BMI), smoking status, drinking frequency, exercise frequency and coffee intake, the serum GGT level was positively associated with fasting blood glucose (p<0.01), total cholesterol (p<0.01), and triglyceride (p<0.01) in men, and it was positively associated with fasting blood glucose (p<0.01), total cholesterol (p<0.05), triglyceride (p<0.01), and uric acid (p<0.01) in women. The associations were not significantly different depending on the status of alcohol drinking or obesity, except for the associations of serum GGT with diastolic blood pressure (P for interaction=0.04) and uric acid (P for interaction=0.04) between the lean and obese subjects. Conclusions : Serum GGT levels within the normal range were positively associated with fasting blood glucose, triglyceride and uric acid in most subgroups irrespective of the drinking or obesity status. These results suggest that GGT has important clinical implications as being more than just a marker of alcohol consumption and hepatobiliary disease.

웹 기반형(Web-based) 플랫폼 노동자의 임금 결정요인: 이전 고용주에 의한 평가의 관점에서

임지선,Lim, Jisun 한국디지털정책학회 2022 디지털융복합연구 Vol.20 No.4

본 연구는 웹 기반형(web-based) 플랫폼 노동자의 임금 결정에 관한 연구이다. 이를 위해 2018년 9월 전 세계적 플랫폼 노동시장 중 하나인 Freelancer.com에서 웹 크롤링(web-crawling)한 총 3,575명의 구직자 정보를 사용하였으며, 전통적 노동시장에서 유의하였던 학력, 경력과 더불어 플랫폼 노동시장에서 새롭게 사용 가능해진 이전 고용주에 의한 평가가 플랫폼 노동자의 임금상승에 유의한 영향을 주는지 OLS 및 QR 분석방법을 사용하여 추정하였다. OLS 분석결과 플랫폼 노동자의 임금은 과거 유의하였던 학력, 경력뿐 아니라 이전 고용주에 의한 평가(리뷰 수)에 의해서도 영향을 받는 것으로 나타났다. 다만, QR 분석결과 플랫폼 노동자의 임금수준이 상승함에 따라 교육보다는 경력이 리뷰 수보다는 추천 수가 플랫폼 노동자의 임금상승에 더욱 유의미한 영향을 주는 것으로 나타났다. The purpose of this study was to find the wage determinants of web-based platform workers. For this purpose, a total of 3,575 web-based platform workers' information from Freelancer.com, a global platform labor market, in September 2018 were used and whether or not newly available indicators such as evaluations by previous employers had a significant effect on the wage increase of platform workers using OLS and QR methods. As an OLS estimation results, the number of reviews, as well as education and experience, affects the wages of platform workers. However, as a result of the QR estimation, experience rather than education, recommendation rather than a review has a more significant effect on the wage of web-based platform workers as the wage level rises.

서양 수사학 방법론을 적용한 옌푸(嚴復)의 『논세변지극(論世變之亟)』분석

임지선,나민구 한국중국언어문화연구회 2022 한중언어문화연구 Vol.- No.66

수사학은 유구한 역사를 가진 학문 중 하나로, 단순히 설득의 기법, 재주를 연구하는 것이 아니라, 공동체 발전과 사회의 공정을 실현할 제도를 만들기 위해 탄생한 학문이다. 서양 수사학은 고대에서부터 시작된 학문이지만, 그 핵심인 ‘설득’은 지금까지 매우 중요한 능력으로 인정받고 있다. 이 연구는 시대적으로 중요한 가치를 지녔으며, 설득 요소가 두드러진 산문을 서양의 수사학적 측면에서 분석하고, 더 나아가 현대의 설득 능력에 적용되는 것을 목표로 하며, 중국의 지식인 옌푸(嚴復, 1854-1921)의 『논세변지극』을 연구 대상으로 삼는다. 『논세변지극』은 망국(亡國)의 위기에서 구국(救國)을 향한 지식인의 고뇌와 갈망이 묻어있는 동시에 진정한 부국강병으로 가는 길에 대한 자신의 견해를 독자에게 설득하는 글이다.

4차 산업혁명시대, 생산적인 프로슈머 이코노미로의 전환을 위한 정책제언: 일자리문제 해결을 위한 인적자원개발의 관점에서

임지선 한국정보화진흥원 2017 정보화정책 Vol.24 No.2

The Fourth Industrial Revolution, which is based on the development of information and communication technology (ICT), is expected to replace human knowledge work, which will cause problems of mass unemployment and wide income gap from job polarization. Furthermore, the change is expected to be rapid and wide, demanding proactive measures to respond to such abrupt social changes. However, previous literatures assume that the traditional form of employment will continue and provide limited solutions only. On the other hand, the Fourth Industrial Revolution will enable transition to the Prosumer Economy, which will ultimately lead consumers to become producers through increased job flexibility. If the prosumer economy arrives and the consumers become producers, it will no longer be the matter of finding workplace but rather, the matter of finding the work itself. In this regard, the new technologies of the Fourth Industrial Revolution can be the fundamental solution to such job issues. This paper suggests stable transition to the Prosumer Economy in order to solve the job issues in the age of the Fourth Industrial Revolution. In order to effectively support the process, this paper suggests first, ensuring the amount of education by shortening labor time; second, facilitating life-time education through free online education service; and third, closing the digital divide through mandatory use of the e – government system. 정보통신기술 발달에 기반하고 있는 4차 산업혁명은 인간의 지식노동을 대체함으로써 대량실업문제 및 일자리 양극화를 통한 소득격차문제를 확산시킬 것으로 예상되고 있다. 더욱이 그 변화의 속도와 범위가 빠르고 광범위할 것으로 예상되어 급격한 사회변화에 따른 선제적 대응조치 마련을 요구하고 있으나, 기존연구에서는 전통적 형태의 일자리가 미래에도 지속될 것이라는 가정 하에 제한적인 해결방안만을 내어놓고 있다. 한편, 정보통신기술은 기존직무의 유연화 과정 등을 통해 기업의 생산방식을 변화시키고 있는데. 이러한 기존직무의 유연화 과정은 궁극적으로 소비자가 생산자가 되는 프로슈머 이코노미로의 전환을 가능하게 할 것으로 보인다. 만일, 소비자가 생산자가 되는 프로슈머 이코노미가 도래하게 될 경우 기존의 일자리문제는 더 이상 일자리문제가 아닌 일거리 문제로 대체될 수 있는데, 이것이야말로 새로운 기술을 활용한 일자리문제의 근본적 해결방안이 될 수 있다. 결과적으로 본 논문은 4차 산업혁명시대 일자리 문제 해결을 위해 프로슈머 이코노미로의 안정적 전환을 제안하고 있으며, 보다 생산적인 프로슈머 이코노미로 전환하기 위한 인적자원개발의 관점에서 첫째, 노동시간단축을 통한 교육시간의 확보, 둘째, 온라인 대중교육 무료지원을 통한 평생교육 활성화, 셋째, 전자정부 사용 의무화를 통한 정보격차해소 방안을 제안하고자 한다.

Governmental or Social Support of Bariatric Surgery in the Asia-Pacific Region

임지선,조영혜,Hiroshi Yamamoto,Alvin Eng,Tania Markovic,김경곤 대한비만학회 2017 The Korean journal of obesity Vol.26 No.1

Herein we review the management status of governmental financial support of bariatric surgeries in several Asia-Pacific areas of Japan, Singapore, and Australia, which were discussed in the 2016 International Congress on Obesity and Metabolic Syndrome (ICOMES). Patient’s body mass index criteria of bariatric surgery for public support are different one another in the three countries. Whereas laparoscopic sleeve gastrectomy (LSG), Roux-en Y gastric bypass (RYGB), and laparoscopic adjustable gastric banding (LAGB) are applicable in both Singapore and Australia, the coverage of insurance is limited to LSG in Japan. In addition, the surgical fees and equipment costs are not fully covered by public health insurance for performing sleeve gastrectomy in Japan, but patients with morbid obesity can still use public health insurance. In Singapore, the waiting time for surgery in public hospitals is longer on average than for private hospitals. However, patients can obtain subsidies of up to 80% of the costs of surgery in public hospitals, while particularly needy patients may even be able to obtain completely free bariatric surgery through Medifund. In Australia, bariatric surgeries in public sectors are publicly funded, but most bariatric surgeries occur in the private sector and Medicare only reimburses surgical costs in the private sector. Although certain characteristics need to be improved, the access to bariatric surgery has shown steady progress through public support in each of these countries.

Protective Effect of Dioscorea batatas Peel Extract Against Intestinal Inflammation

임지선,오지선,변시율,이정순,김정상 한국식품영양과학회 2018 Journal of medicinal food Vol.21 No.12

Dioscorea batatas Decne (Chinese yam), a perennial trailing plant, has been used as a traditional medicine due to its beneficial biological effects. Recent studies reported that yam bark powder increased antioxidant enzyme activity and exerted an anti-inflammatory effect in drug-induced liver injury or colorectal cancer in rats. In this study, we examined whether ethanol extracts of yam bark (peel) could ameliorate the macrophage-induced inflammatory damage of colonic epithelial cells in culture and in an acute colitis mouse model. Human HCT116 colorectal epithelial cells and/or lipopolysaccharide (LPS)-activated murine Raw 264.7 macrophages were treated with the yam bark extract, followed by biochemical examination of cellular cytokine and antioxidant enzyme expression levels. Our results demonstrated that the yam bark extract decreased nitric oxide production and proinflammatory protein expression in LPS-activated Raw 264.7 cells, and reduced the level of reactive oxygen species in hydrogen peroxide-challenged HCT116 cells. Moreover, yam bark extract attenuated dextran sulfate sodium (DSS)-induced acute colitis in BALB/c mice. These findings suggest that oral supplementation with yam bark extract inhibited DSS-induced colon inflammation through upregulation of antioxidant enzymes and subsequent downregulation of inflammatory proteins.

Ferric Nitrilotriacetate로 유도된 신장손상에 대한 품종별 콩의 방어활성

임지선,서지연,황영현,김정상,박지아 대한암예방학회 2009 Journal of cancer prevention Vol.14 No.4

Soybean is a rich source of phytochemicals as well as protein and lipid. Isoflavones have been reported to possess various health benefits including anti-carcinogenesis, anti-aging, and anti-oxidative activities while anthocyanins revealed a good antioxidant activity. Two varieties of soybean Aga No 3 and No 4, newly bred in Kyungpook National University, contain excessively high level of isoflavones, compared to regular varieties such as Daemang No 2 and Black Ilpoom No 1. Four varieties of soybean used in the present study revealed strong antioxidant activity as assessed by DPPH and DCFDA assay. In vivo experiment in which mice were treated with ferric nitrilotriacetate (Fe-NTA) known to induce kidney damage by oxidative stress demonstrated that diets containing anthocyanin-rich varieties such as Black Ilpoom No 1 and Aga No 4 were most protective from kidney damage induced by Fe-NTA.

O2O서비스의 경제적 효과분석: 차별화된 서비스 재화에 대한 질적 정보중개기능의 관점에서

To examine the economic impact of O2O services regarding qualitative information sharing of service goods, this paper uses one of the most representative models of information search cost and price dispersion. The results show, on the one hand, that O2O services effectively lower search costs of qualitative information regarding service goods and that such services also tend to increase consumer welfare. On the other hand, our findings suggest that O2O services may be expected to lead to more decentralized markets(unlike traditional e-businesses). In other words, many producers with differentiated products can operate while targeting different groups with diverse preferences. This has become feasible because service goods are consumed offline despite the fact that information is shared online. Therefore, sharing qualitative information with respect to O2O services can not only increase consumer welfare but also promote greater variety in the marketplace.
