본 연구에서는 항공화물 서비스 경쟁력 평가 요소 및 중요도를 결정하고, 실제 항공화물 운송사에 대한 서비스 품질을 평가하고자 한다. 항공화물 서비스에 대한 평가 대상을 Skyteam의 주요 화물 서비스 상품인 Equation Heavy, Equation, Variation, Dimension로 정하였고, 이 서비스 상품에 대한 품질 평가를 실행하였다. 본 분석은 전문가 설문 조사, AHP 및 퍼지적분(Fuzzy Integral) 등의 방법론들을 적용하였고, 선행 연구와 전문가 인터뷰, 그리고 요인분석을 통해 주요 평가요소를 추출하여 서비스 품질 평가모형을 구축하였다. 주요 평가요소는 인프라, 신뢰성, 신속 대응성, 경제성, 안전성 요소 등을 설정하였다. 이 다섯 가지 요소를 바탕으로 하여 수게노(Sugeno)가 제안한 퍼지 적분 방법론에서 파생된 알고리즘을 적용하여 최종으로 화물 서비스 품질을 분석하였다. This research explores the relative importance of factors and service items that influence the air cargo service quality for provision services by the Skyteam Cargo in the Korean market. In general, the Skyteam Cargo provides a package of services which are different functions and operations of service such item as Equation Heavy (heavy and large express freight), Equation (small express freight), Variation (special freight), and Dimension (general freight). To carry out the research, the expert questionnaire survey, the Analytic Hierarchy Process (AHP) analysis had adopted to evaluate the level of quality for the provision air cargo operation services by the Skyteam Cargo at Incheon International Airport. Based on an expert survey and the AHP, five core service factors, namely, infrastructure as installed facilities, reliability, promptness, efficiency, and safety are defined.

Anthocyanins are water-soluble plant pigmentsthat give rise to the red, purple, or blue colors observed inmany crops. Especially purple pigment of colored rice representbiological activities has been an increased interest, due tothe functional meal as a staple food. These health benefitshave been attributed to antioxidant property of anthocyanin. However, there have been little genetic source for developmentof new and various colored rice variety. A recently developednew variety, ‘Jungmo1020’, showed an unique characteristicof blue color of rice grain hull. We identified the pigmentpetunidin-3-O-glucoside (Pt-3-G) as a major compound witha value of 176.3±2.3 mg/100 g (68.3%) from 80% MeOHwith 1% HCl extracts by UPLC/MS/MS. The content of Pt-3-G inthe extracts using a solvent of 100% MeOH with 1% HClwas the highest with the values of 183.8±2.5 mg/100 g. Inaddition, these extracts showed excellent antioxidatative activitiesby DPPH and ABTs assay.

교통 빅데이터를 활용한 속보성 지역경기종합지수 도출 연구

나지은,홍정열,강유정,김동호,천승훈 대한교통학회 2021 대한교통학회 학술대회지 Vol.85 No.-

최근 코로나19로 인해 서민경제의 부실화, 상권침체, 실업문제의 심화 등 다양한 경제 이슈가 사회적인 화두로 떠오르고 있다. 이러한 지역 경제 상황을 정확하고 빠르게 판단하고, 시의적절한 정책을 수립하기 위해서는 지역 내 경기진단을 위한 적절한 지표 선정 및 산정 방법론을 체계화하는 것이 중요하다. 해외에서는 통신데이터 등 교통 관련 빅데이터를 활용하여 지역경기지수를 도출하는 연구가 수행되어 왔다. 그러나 국내에서는 아직까지 교통 빅데이터를 통해 도출된 시민의 통행패턴과 지역경기지수와의 관계를 분석하는 연구가 시도된 적이 없다. 따라서 본 연구에서는 울산광역시를 대상으로 지역경제활동을 예측하기 위해 다양한 실시간성 교통 빅데이터를 활용하였으며, 통행패턴과 지역경기종합지수 간의 상관관계 및 추세 유사성 분석 등을 통해 경제 변화를 초기에 식별할 수 있는 속보성 경기종합지수를 작성하고자 하였다. 본 연구에서 제안된 교통데이터와 경기지표들은 시계열적 경제추이를 추적하는데 유용하게 사용될 수 있을 뿐만 아니라, 미래경제 상황을 예측하는 척도로 활용할 수 있을 것으로 기대된다.

Sorghum has been consumed as one of theimportant staple food in the semiarid tropics of Africa andAsia. Sorghum is rich in starch, protein, essential vitaminsand minerals and grows relatively well in dry climate regionswhen it compared with other staple food crops. Sorghumhas taken an increased interest due to several studies thatreport about the beneficial effects of sorghum on humanhealth. In the present study, we investigated the antioxidativeand activity of extract of milling by-products (hull and bran)of Korean sorghum cultivar, ‘Hwanggeaumchal’ as well as itsgrain. Hull extract showed the highest total polyphenol contents(29.7±0.2 mg GAE/100 g) and major four pigments content(322.6±14.5 mg/100 g). From results of 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonate (ABTS) radical scavengingactivity, hull extract (IC50, 6.3±0.1 μg/ mL) was also showedthe strongest antioxidative effects. Bran and grain showedsimilar polyphenol, pigments contents and antioxidative effects. We determined cell viability by MTT assay and evaluatedthe anti-inflammatory activity by measuring nitric oxide (NO)of hull, bran and grain methanol extract (0.5% HCl v/v) onRAW 264.7 cells. Hull extract treatment was significantlydecreased NO production with dose-dependant manner. Apigeninidinas one of the major pigment of hull was showedinhibitory activity against NO production without cytotoxicitiy. Therefore, sorghum milling by-products can be used as agood source of antioxidative and anti-inflammatory agents

대장내시경 검사를 위한 적절한 장정결제 선택 : How to Choose the Optimal Bowel Preparation Regimen for Colonoscopy

나지은,김은란 이화여자대학교 의과학연구소 2021 EMJ (Ewha medical journal) Vol.44 No.4

Colonoscopy is commonly used to screen for and diagnose colorectal disease, and adequate bowel preparation is crucial to its quality. As bowel preparation regimens vary, it is important that clinicians understand each and select the proper one for each patient. Accordingly, here we investigated recent studies and describe how to choose the optimal bowel preparation regimen. We detail composition, dosages, efficacy, contraindications, and precautions of commonly used regimens including 4 L polyethylene glycol (PEG), 2 L PEG+ascorbic acid, 1 L PEG+ascorbic acid, trisulfate (oral sulfate solution/ tablets), and sodium picosulfate/magnesium citrate. Here we describe that the most recently introduced 1 L PEG and oral sulfate tablets, which were developed to improve convenience and compliance, differ in composition and efficacy between South Korea and foreign countries. This review presents new evidence of and differences among products to increase clinician understanding.

The air cargo business field gets stuck in the mire as highly competitive arena due to the depression of world economy and less profit margins. The alternatives in which there are various with the service improvement, a deregulation, the complex conveyance system, IT applied systems and other considerations have to be groped for in order to overcome such kind of the crisis. In spite of these difficulties, the speed and reliability requirements of customers in the contemporary supply chain management in global has made air cargo the fastest-growth area in the cargo industry. This research explores the relative importance of factors and service items that influence the air cargo service quality for provision services by the Skyteam Cargo in the Korean market. In general, the Skyteam Cargo provides a package of services which are different functions and operations of service such item as Equation Heavy (heavy and large express freight), Equation (small express freight), Variation (special freight), and Dimension (general freight). To carry out the research, the expert questionnaire survey, the Analytic Hierarchy Process (AHP) analysis had adopted to evaluate the level of quality for the provision air cargo operation services by the Skyteam Cargo at Incheon International Airport.
