This study examined consumer perceptions and market trends of Korean food products sold on Amazon, focusing on keyword and review analysis. As Korean cuisine gains global attention, particularly in the U.S., it is essential to understand how international consumers perceive these products. Data were collected from Amazon, encompassing product details and customer reviews of Korean food categories. Frequently mentioned keywords in the reviews were identified, and customer sentiments were explored using Python-based data analysis. The results suggest that taste, especially spiciness and sweetness, is a key determinant of consumer satisfaction. Although Korean food was generally well-received, packaging and delivery issues were common complaints. These findings provide strategic insights for Korean food manufacturers aiming to expand globally, emphasizing the need for tailored product development and enhanced logistics.

본 연구는 Esping-Andersen의 복지레짐을 대표하는 영국, 독일, 스웨 덴 청년 빈곤 관련 정책동향을 탐색하고 실태를 분석하는 데 주요 목적 을 두었다. 세 국가의 청년실업 해소를 위한 노동시장 정책을 분석한 결 과 공통적으로 불평등의 구조적 완화에 방점을 두고 있으며, 상대적 빈 곤율 및 니트족 비율과 같은 지표를 활용하여 관련 정책의 성과를 실증 적으로 탐색하는 데 제도적 노력을 기울이고 있었다. 아울러 정책 프로 그램 사례를 분석한 결과 파트너십, 신뢰, 인간적 관계 형성과 같은 사회 적 자원 및 지지가 중요한 성공요인으로 파악되었다. 유럽연합 통계청 (Eurostat)의 자료를 바탕으로 2014년-2023년 기간 세 국가의 청년 빈 곤율과 니트비율을 시계열 분석한 결과 독일의 청년 빈곤율은 코로나가 시작된 2020년 22%로 급증한 추이가 포착되었다. 스웨덴 또한 청년 빈 곤율과 니트비율은 2019년까지 감소세를 보이다 2020년 이후 니트비율 은 7%로 증가하는 추세가 확인되었다. 유럽연합 탈퇴로 2019년까지 통 계청 자료가 공개된 자유주의 모델의 영국 또한 2017년 이후 청년 빈곤 율과 니트비율이 증가하는 양상이 나타났다. 본 논문의 결론에서는 각 국가의 사례로부터 한국 빈곤 청년층의 문제를 완화하기 위한 정책적 시 사점과 교육제도 혁신의 필요성을 심도 있게 논의하였다.

This study aims to investigate protein consumption market trends in Korea. Protein consumption was divided according to the protein source into meat, fishery, and plant-based protein. To accomplish the goal of this study, food purchase data from 525 households panels collected by the Rural Development Administration over the last 10 years were used. The results of the study showed an increase or decrease in protein consumption by protein type over the last 10 years, and a reason to explain this change has been suggested. Specifically, this study found a dramatic increase in the consumption of several proteins, including beef sirloin, beef tenderloin, seasoned beef & steak, pork belly, pork shoulder, pork neck, seasoned pork, pork cutlet, sweet and sour pork, canned ham, chicken drumstick, chicken breast, dak gangjeong, Chinese fried chili chicken, salmon, eel, abalone, squid, octopus, webfoot octopus, octopus minor, canned whelk, tofu, cold bean soup,and plant-based milk. Some items showed no increase in consumption (such as beef jerky, pork rib, sausage, bacon, whole raw chicken, cutlass fish, oyster, fish cake, crab stick, surimi sausage,and canned fishery), whereas a few items showed decreased consumption (e.g., mackerel, pollack, cod,and canned tuna)

Google Trends is a useful tool not only for setting search periods, but also for providing search volume to specific countries, regions, and cities. Extant research showed that the big data from Google Trends could be used for an on-line market analysis of opinion sensitive products instead of an on-site survey. This study investigated the market share of tumor necrosis factor-alpha (TNF-α) inhibitor, which is in a great demand pharmaceutical product, based on big data analysis provided by Google Trends. In this case study, the consumer interest data from Google Trends were compared to the actual product sales of Top 3 TNF-α inhibitors (Enbrel, Remicade, and Humira). A correlation analysis and relative gap were analyzed by statistical analysis between sales-based market share and interest-based market share. Besides, in the country-specific analysis, three major countries (USA, Germany, and France) were selected for market share analysis for Top 3 TNF-α inhibitors. As a result, significant correlation and similarity were identified by data analysis. In the case of Remicade’s biosimilars, the consumer interest in two biosimilar products (Inflectra and Renflexis) increased after the FDA approval. The analytical data showed that Google Trends is a powerful tool for market share estimation for biosimilars. This study is the first investigation in market share analysis for pharmaceutical products using Google Trends big data, and it shows that global and regional market share analysis and estimation are applicable for the interest-sensitive products.

The principal aims of the review paper are (1) to establish broad overview information, both qualitative and quantitative, relating to the world market for polyacrylonitrile (PAN) or pitch-based carbon fibers; and (2) to generate an effective analysis and break down of consumption by process route and eventual end-use. The review paper also designed specifically to provide subscribers with an accurate, independent, and realistic assessment of the current status and future perspective of the market for carbon fibers in the world. The world market for carbon fibers continues to grow rapidly, fuelled by new industrial end uses, such as sport and leisure goods, aerospace, automotive applications, civil engineering and infrastructure repair, and immerging applications in energy generation. Demands for properties of carbon fibers used in those applications include many things such as strength, toughness, fatigue property, corrosion resistance, heat resistance, etc., and these become to be higher level. On the other hand, demands for manufacturing technologies of carbon fibers become to be difficult with these demands for properties, and these are wide variety such as high efficiencies, high qualities, many functions, labor saving, and low cost. In this review paper, thus, the recent carbon fibers corresponded to these needs, and its latest manufacturing technologies as well as market prospects are described.

Probiotics are defined as live microorganisms that, when administered in adequate amounts, conferred a health benefits on the host by FAO/WHO. Probiotics can help to maintain the balance of microflora in the digestive tracts and these beneficial activities provide prevention from diseases to the host. Bifidobacteria and Lactobacilli strains are most commonly used as probiotics. In many categories, probiotics are applied to different types of products like foods, dietary supplements, functional foods, and even drugs. Fermented dairy products are the most popular and efficient vehicle for administration. Probiotics are part of the much larger functional food and beverage market and one of the prime beneficiaries of the latest growth trend of fortified and functional foods. Until 2011, Japan, U.S, and Western Europe were the largest markets for probiotics, both in terms of consumption as well as growth. Since 2011 however, Asia Pacific, Eastern Europe and Brazil have had a tremendous rise in revenue from probiotics and are expected to remain in the product growth stage over the next five years. The primary reasons for the success of probiotics fortified foods in these markets are the increasing awareness about their potency and efficacy and the willingness of customers to pay extra for something healthy. The global probiotics market revenue was 27.9 billion US dollars in 2011 and is expected to reach 44.9 billion US dollars in 2018 with 6.8% annual growth rate. Growing consumption of fermented milks and increasing concerns over digestive and gut health are major driving forces and these demands has translated into increased R&D spending and new product developments over the last three years.
