The purpose of this study is to establish a strategy to activate the export of Korean paprika to Vietnam. For this, we survey 202 adults in Vietnam, and analyzed the paprika purchase and consumption behavior, preferences, considerations, and willingness to pay. Most of respondents had purchased paprika, and offline grocery stores are the major purchasing location of paprika. The price elasticity of Korean paprika is greater than 1, showing more elasticity than other origins, and it is advantageous to implement the price reduction strategy. The number of household members and the level of education affect purchasing intentions. In conclusion, product composition targeting small households, pricing strategy, and K-Food marketing are appropriate.

한국 시・군・구의 네트워크 중심성 측정

서영창,최원회 한국지도학회 2018 한국지도학회지 Vol.18 No.3

The purpose of this study is a measurement of the network centrality of siㆍgunㆍgu in Korea. For this purpose, this study measured the size of centrality between 229 city, county or district areas across the country in the form of score using an origin-destination matrix based upon the commuting data of 229 cities, counties or districts of the ‘Population and Housing Census’ conducted by KOSTAT (Korea Statistics) in 2015. In this study the centrality scores of 229 city, county or district areas across the country were measured because previous studies have never conducted a centrality investigation on all 229 city, county or district areas across the country. The centralities measured in this study were degree centrality, eigen vector centrality and Bonacich beta centrality. Among these centralities, the Bonacich beta centrality is the generalization of degree centrality and eigen vector centrality. In this study the result values of degree centrality, eigen vector centrality and Bonacich beta centrality were compared, as a result it was appeared clearly that the relationship between areas was not complementary but competitive unlike previous studies. Especially, if the relationship between areas is not complementary but competitive, it was found that a result value of centrality with high objectivity is obtained by measuring with the Bonacich beta () centrality. 본 연구의 목적은 ‘한국 시·군·구의 네트워크 중심성 측정’이다. 이러한 연구목적의 달성을 위해 전국 229개 시·군·구 간의중심성 크기를 ‘2015년 인구주택총조사’의 전국 229개 시·군·구의 통근통행 O-D 행렬을 이용하여 점수 형태로 측정하였다. 본연구에서 전국 229개 시·군·구를 대상으로 중심성 점수를 측정한 것은 기존의 연구 중에는 전국 229개 시·군·구 전체를 대상으로조사한 사례가 없기 때문이다. 본 연구에서 측정한 중심성은 세가지인데, 연결정도 중심성과 고유벡터 중심성, 그리고 연결정도중심성과 고유벡터 중심성을 일반화시킨 보나시치 베타 중심성이 그것들이다. 본 연구에서 연결정도 중심성, 고유벡터 중심성및 β<0인 보나시치 베타 중심성을 사용하여 전국 229개 시·군·구의 세가지 중심성을 구하고, 이 세가지 중심성의 결과값을비교한 결과, 지역 간 상호관계는 기존 연구에서 나타난 상호보완적 관계가 아니라 상호경쟁적 관계임이 명확하게 드러났다. 특히, 지역 간 상호관계가 상호경쟁적 관계일 경우 보나시치 베타(β<0) 중심성으로 측정하여야 정확성이 높은 중심성 결과값을얻을 수 있는 것으로 나타났다.

서영창,정다은,양성범 한국식품유통학회 2024 食品流通硏究 Vol.41 No.1

The purpose of this study is to identify the current status of nutrient quality of processed foods as the consumption of processed foods is expanding due to changes in dietary habits. For this, we established a definition of nutrient quality and evaluation principles, and developed a Nutrients Quality Index(NQI) for processed foods. The NQI is calculated through the sum of the Positive Nutrients Indicator(PNI) and the Negative Nutrients Indicator(NNI). In addition, the range of indicators was divided into three types for calculatio, and the third type was adopted.. As a result, the overall NQI average for the category was 65.54, with 'fish sausage' having the highest of 95.09, and 'beverages' having the lowest of 7.68, with 'carbonated beverages' having the lowest of -1.16. Therefore, among the processed food categories, 'fish sausage' has the highest nutritional quality, and 'beverages' has the lowest quality. This will allow relevant organizations to understand the current state of nutritional quality of processed foods on the market and use it as a basis for establishing policies related to processed foods. Utilizing the NQI on processed food packaging is expected to help consumers more intuitively access nutritional information when choosing a product, which will also help formulate future food and nutrition policies.

가공식품의 영양성분 품질지수 개발에 관한 연구

서영창 ( Seo Young-chang ),정다은 ( Jung Da-eun ),양성범 ( Yang Sung-bum ) 한국식품유통학회 2023 한국식품유통학회 학술대회 Vol.2023 No.1

본 연구의 목적은 식생활의 변화로 인해 가공식품 소비가 확대됨에 따라 가공식품의 제품별 영양성분 품질에 대한 현황을 파악하고자 하는 것이다. 이를 위해 영양성분 품질에 대한 정의를 확립하고, 평가원칙을 수립한 후 가공식품의 제품별 영양성분 품질지수(Nutrient Quality Index: NQI)를 개발 및 도출하였다. NQI는 인간이 식품을 섭취함으로써 공급받는 영양성분이 신체의 성장과 생리적 작용 및 발달에 적합한 정도를 의미한다. NQI는 긍정적 영양성분의 평가지수(Positive Nutrient Index: PNI)와 부정적 영양성분 평가지수(Negative Nutrient Index: NNI)의 합을 통해 산출한다. 또한, 산출을 위해 평가지표 범위를 세 가지 유형으로 구분하였다. 그러나 평가지표 범위의 부재, 평가지표와 개별 영양성분 중량 간의 괴리 등의 취약점이 드러나 이를 해결하기 위해 평가지표 범위를 1일 음식 평균 음식 섭취량을 100g당 영양성분 기준치로 환산을 하여 평가 대상 자료의 중량과 일관성을 유지하였다. 연구결과, 전체 영양성분 품질지수의 평균은 65.54점이며, ‘식육가공품류 및 포장육’ 내 ‘식육추출가공품’이 99.49점으로 가장 높았으며, ‘음료류’가 7.68점으로 가장 낮았고 그 중 ‘탄산음료’가 ‘-1.16점’으로 최솟값을 나타냈다. 따라서, 가공식품 품목군 중 대분류로는 ‘식육가공품류 및 포장육’의 영양성분이 고품질이며, ‘음료류’의 품질이 가장 낮음을 의미한다. 다만, 식육가공품 및 포장육의 경우 활용된 자료 내에서 소수의 비중이었기 때문에 해당 결과만으로 전체 가공식품 품목군의 대표적 영양성분 고품질 제품이라 일컫는 것은 한계가 있다. 따라서, 관련 기관에서는 보다 다양한 표본을 수집하고 주기적으로 영양성분 품질 지수를 산출하여 영양성분 품질의 추이를 검토할 것을 제안한다. 해당 추이의 지속적 관찰 결과를 토대로 향후 식품 영양 정책 수립에 도움이 될 것으로 판단된다.

김영건,서영창 啓明大學校 産業經營硏究所 2003 經營經濟 Vol.36 No.2

Many problems have appeared during the process from the industrialized society to the information society. This research was about the methods and types of the cyber-counselling service among the problems. The purpose of this research was presenting the alternatives about managing of cpber-counselling website and cyber-counselling center for teenagers, which are related with the syndromes resulted from the rapid spread and utilization of PC. The major alternatives presented. are those for the types of cyber-counselling, the classification of cyber-counselling examples, the role of cyber-counselor, the effective operation of cyber-counselling center, and the settlement of cyber-culture. But these alternatives are not perfect to solve the cyber-syndromes of teenagers. So It is regarded that this kind of research has to be done continuously from now on.

Systems Biology of Human Microbiome for the Prediction of Personal Glycaemic Response

kirtipal nikhil,서영창,손장원,이선재 대한당뇨병학회 2024 Diabetes and Metabolism Journal Vol.48 No.5

The human gut microbiota is increasingly recognized as a pivotal factor in diabetes management, playing a significant role in the body’s response to treatment. However, it is important to understand that long-term usage of medicines like metformin and other diabetic treatments can result in problems, gastrointestinal discomfort, and dysbiosis of the gut flora. Advanced sequencing technologies have improved our understanding of the gut microbiome’s role in diabetes, uncovering complex interactions between microbial composition and metabolic health. We explore how the gut microbiota affects glucose metabolism and insulin sensitivity by examining a variety of -omics data, including genomics, transcriptomics, epigenomics, proteomics, metabolomics, and metagenomics. Machine learning algorithms and genome-scale modeling are now being applied to find microbiological biomarkers associated with diabetes risk, predicted disease progression, and guide customized therapy. This study holds promise for specialized diabetic therapy. Despite significant advances, some concerns remain unanswered, including understanding the complex relationship between diabetes etiology and gut microbiota, as well as developing user-friendly technological innovations. This mini-review explores the relationship between multiomics, precision medicine, and machine learning to improve our understanding of the gut microbiome’s function in diabetes. In the era of precision medicine, the ultimate goal is to improve patient outcomes through personalized treatments.

Polydopamine coating in organic solvent for material-independent immobilization of water-insoluble molecules and avoidance of substrate hydrolysis

유인성,전혜진,이규의,도민재,서영창,Haesung A. Lee,이해신 한국공업화학회 2017 Journal of Industrial and Engineering Chemistry Vol.46 No.-

Polydopamine (pDA) coating is thefirst material-independent surface chemistry utilized in energystorage systems, environmental technology, and biomaterial science. However, the conventional coatingmethod requires use of aqueous solutions, which restrict immobilization of water-insoluble moleculesonto surfaces, and the coating cannot be applied to degradable polyester substrates. Herein, methods toform pDA in organic protic solvents (o-pDA) with fast coating kinetics resulting in50 nm in thicknessjust for 4 h. One-step immersion of surfaces in a one-pot mixture of a water-insoluble molecule,dopamine, and piperidine results in o-pDA coating with robust surface immobilization of molecules ofinterest.
