This study aimed to investigate and analyze the current state of city brands, which became important as a means of competition due to a shift from competition among nations to competition among cities making up a nation in the global age, and promote the vitalization of Cheongju's city brand. As for methodology, the study reviewed theories about the types of metaverse technology, which attracts attention as a means of providing information and experience effectively beyond the limited restrictions of the reality, as well as city brands, marketing communication strategies, and mental models. Metaverse technologies and city brands were categorized by the type before a case study and analysis. The cases of metaverse technologies were analyzed in terms of advantages and disadvantages. The cases of city brands were put through comparative analysis by the type and comprehensive analysis before each technology was examined for its characteristics by the type. In the case analysis of the investigated city brands, the elements of marketing communication strategies identified in the theoretical review were assessed and analyzed qualitatively along with the Korean version of the Brand Personality Scale in Aaker(1997) fit for the sentiment of Korean people including "affection," "passion," "sophistication," and "sincerity." Also assessed and analyzed qualitatively was a scale that added the same keywords from appraisal search results by the Korea Creative Content Agency and from the search results of changing emotional words in the SNS Big Data analysis service. Based on the results, "newness," which extracted the elements of a successful brand, was set as an item in a city brand personality scale. In an effort to organize the content of Cheongju's successful city brand vitalization, the investigator analyzed the characteristics of each metaverse technology identified above by the type with the set brand personality scale and applied metaverse technologies fit for the resulting elements including natural, cultural, and service resources. In addition, the study built a mental model and proposed three methods to create and vitalize a successful city brand to provide users with quality service. First, Cheongju needs to come up with creative ideas that make use of its diverse histories and cultures to reinforce its cultural resource-based city brand as "cultural city of Cheongju as a city of archival culture" by obtaining original and creative products or ideas based on communication, collaboration, and research through private-public governance. Secondly, Cheongju needs to provide people with new content and have them share its experiences to promote its reinforced city brand and show its appeal index and advanced competitive edge with its reinforced city brand through diverse and active promotional methods. Finally, Cheongju needs to provide people with new and creative experiences based on the content of its city brand that will develop through consistent management and improvement beyond the simple building of its city brand. As the COVID-19 pandemic continues on, it is difficult to provide experiences based on experiential content efficiently. Trying to overcome the difficulties, the study proposed a plan of using metaverse technology in creative experiential content created by the three methods to build and vitalize a successful city brand. The study also proposed content composition and design to provide information and experiences effectively within a metaverse. Using a five-point Likert scale of satisfaction and a survey to assess agreement points, the study demonstrated whether there was an agreement between the vitalization of Cheongju's city brand and the mental model of a developer and user through the content design. Cheongju's city brand recorded a high satisfaction level at 3.975 out of 5 in recognition improvement through the content of history and culture metaverse. As for agreemnet between different mental models, there was high agreement at 3.700 out of 5 at the first, second, and third stage of content, which correspond to implementation, member registration and log-in, and content choice, respectively. There was closing at mean 2.895 points at the fourth and fifth stage of history and culture metaverse content and sharing. These findings indicate that there is a closing between a user's mental model and a developer's mental model. If Cheongju City reflects and implements a couple of improvement measures identified in the survey by creating a design of history and culture metaverse content based on these findings, it will be able to make a contribution to the vitalization of its city brand. 본 논문의 연구 목적은 지구촌 시대에 국가 간 경쟁 구도에서 국가를 구성하는 도시 간 경쟁 구도로 변해 경쟁의 수단으로 중요해진 도시 브랜드 현황을 조사하고, 분석하여 향후 청주시 도시 브랜드의 활성화를 도모하는데 있다. 연구 방법은 현실의 제한된 한계를 넘어 효과적으로 정보와 경험을 제공하기 위한 수단으로 주목받고 있는 메타버스 기술의 유형과 도시 브랜드, 마케팅커뮤니케이션 전략, 심성 모형에 관한 이론적 고찰을 실시하였다. 메타버스 기술과 도시 브랜드를 유형별로 분류하여 사례 조사 및 분석하였다. 조사된 메타버스 기술 사례들의 장·단점 분석을 진행하였고, 도시 브랜드 사례들은 유형별 비교 분석과 종합 분석을 통해 각 기술의 유형별 특징을 도출하였다. 조사된 도시 브랜드의 사례 분석 시, 이론적 고찰에서 도출된 마케팅커뮤니케이션 전략 요소와 브랜드 개성을 측정하는 Aaker(1997)의 브랜드 개성 척도(Brand Personality Scales: BPS) 유형을 한국인 정서에 맞춰 ‘정감’, ‘열정’, ‘세련됨’, ‘성실’로 대체하였다. 또한 한국콘텐츠진흥원에서 진행한 감정 검색 결과와 SNS 빅데이터 분석 서비스의 감성어 변화 검색 결과에서 동일하게 도출된 키워드를 추가한 척도를 정성평가 및 분석하여 성공적인 브랜드 구축 요소를 추출한 ‘새로움’을 도시 브랜드 개성 척도로 설정하였다. 청주시의 성공적인 도시 브랜드 활성화 콘텐츠 구성을 위해 앞서 도출된 각 메타버스 기술의 유형별 특징을 설정된 브랜드 개성 척도로 분석하였고, 결과로 도출된 요소인 자연 자원형, 문화 자원형, 서비스 자원형의 요소들에 적합한 메타버스 기술을 적용하였다. 또한 사용자들에게 양질의 서비스를 제공하기 위하여 심성 모형을 구축하고 성공적인 도시 브랜드 구축 및 활성화 방법 3가지를 제시하였다. 첫째, 민·관 거버넌스 구축을 통한 소통과 협력, 연구로 독자적이고 창의적인 결과물 혹은 아이디어를 도출하여‘기록문화의 도시, 청주 문화도시’의 문화 자원형 도시 브랜드를 강화하기 위한 청주시의 다양한 역사·문화를 활용하는 창의적인 아이디어를 도출해야 한다. 둘째, 강화된 도시 브랜드의 홍보를 위해 사람들에게 새로운 콘텐츠를 제공하여 해당 경험을 공유하게 하고, 다양하고 적극적인 홍보 방법을 통해 강화된 도시 브랜드의 매력 지수와 앞선 경쟁력을 보여주어야 한다. 셋째, 도시 브랜드 구축에 그치지 않고, 꾸준한 관리와 개선을 통해 발전되는 도시 브랜드의 콘텐츠로 사람들에게 새롭고 창의적인 경험을 제공해야 한다. 최근 팬데믹 현상으로 인해 체험 콘텐츠를 통한 경험을 효율적으로 제공하지 못하는 것을 극복하기 위해 세 가지로 분류한 성공적인 도시 브랜드 구축 및 활성화 방법으로 도출된 창의적인 체험 콘텐츠에 메타버스 기술을 활용하는 방안을 제시하였으며, 메타버스 내에 효과적으로 정보와 경험을 제공하기 위한 콘텐츠의 구성 및 디자인을 제안하였다. 이후 해당 콘텐츠 디자인을 통해 청주시 도시 브랜드의 활성화 여부 평가와 개발자 및 사용자 심성 모형 일치 여부를 Likert 5점 척도 만족도와 일치 여부 점수 평가를 통한 설문 방법으로 증명하였다. 역사·문화 메타버스 콘텐츠를 통해 청주시 도시 브랜드의 인지 개선 만족도는 5점 만점에서 3.975점으로 높은 만족도를 보였다. 심성 모형 일치도는 콘텐츠의 1, 2, 3단계인 실행, 회원가입 혹은 로그인, 콘텐츠 선택은 5점 만점에서 3.700점으로 높은 일치도를 보였다. 4, 5단계인 역사·문화 메타버스 콘텐츠, 공유 단계는 평균 점수 2.895점으로 대체로 근접하는 것으로 나타나 사용자 심성 모형이 개발자 심성 모형과 근접 한다는 것을 알 수 있다. 이러한 결과를 토대로 역사·문화 메타버스 콘텐츠 디자인 구축을 통해 앞서 설문 조사에서 도출된 몇 가지의 개선점을 반영하고, 시행한다면 청주시 도시 브랜드의 활성화에 기여 할 수 있을 것이라 생각된다.

본 연구는 유산균 발효유의 섭취가 과민성 대장 증후군(IBS)의 증상 개선에 미치는 효과를 알아보기 위해 진행 하였다. IBS 환자는 8주동안 하루에 한 번씩 유산균 발효유를 섭취한 그룹(실험군; n = 31)과 placebo (n = 32) 로 나누어 분변 시료를 수집 하였고, 분변 미생물 균총과 분변 내 유해효소, 부패물질 함량, 분변 SCFA를 분석하였다. 실험군에서 분변 내 Lactobacillus 의 균 수는 섭취 전 보다 섭취 8주 후에 그 수가 유의적으로 증가 하였고(P < 0.05) placebo군 에서는 유의적인 차이를 보이지 않았다. 상대적으로 분변 내 E. coli 의 균 수는 실험군에서 섭취 후에 유의적으로 그 수가 감소하였다(P < 0.05). 그러나 분변 내 Clostridium perfringens의 수에는 유의적인 변화가 없었다. 유해효소 (tryptophanase, azoreductase, β-glucosidase, β-glucuroni dase) 의 활성은 섭취 전과 후를 비교하여 실험군 에서 유의적인 차이를 보이지 않았으며, β-galactosidase 활성은 섭취군에서 섭취 전 보다 유의적으로 증가하였다(P < 0.05). 분변 내 부패물질인 ammonia와 indole의 함량은 통계적으로 유의적인 차이는 없었으나 섭취군에서 섭취 후에 감소하는 수치를 보였고 황화수소의 경우에는 섭취 전과 8주 후간의 유의적인 변화는 나타나지 않았다. 이러한 결과로 유산균 발효유의 섭취가 장내 미생물 균총과 환경을 개선시킨 다는 것을 알 수 있었다. 결론적으로 IBS는 장내 균총의 변화에 깊은 연관이 있기 때문에, 유산균 발효유의 꾸준한 섭취는 IBS의 증상을 완화시키는 데 도움이 될 것으로 생각된다. The aim of the present study was to investigate the efficacy of yogurt consumption in the improvement of irritable bowel syndrome(IBS) symptoms. The IBS patients were fed with either yogurt (treatment group; n = 31) or a placebo (n = 32) once daily for 8 weeks. Then, fecal microflora, harmful enzyme activity, and the level of putrefactive metabolites and fecal SCFA were investigated. In the treatment group, the fecal Lactobacillus bacterial counts were significantly higher than those of placebo group (P < 0.05) after 8 weeks of consumption. On the other hand, the fecal E. coli bacterial counts were significantly lower than those of placebo group (P < 0.05) 8 weeks. However, there was no significant difference in the fecal Clostridium perfringens bacterial counts during the experiment period. The harmful enzyme activities (tryptophanase, azoreductase, β-glucosidase and β-glucuronidase) were not significantly different between before and after 8 weeks consumption in treatment group. In the treatment group, β-galactosidase activity significantly higher than those of placebo group (P < 0.05) after 8 weeks of consumption but decrease fecal level of ammonia and indole during yogurt consumption. There were no significant differences in the fecal levels of hydrogen sulfide throughout the experiment in both treatment and placebo groups. These results suggest that ingestion of yogurt can improve intestinal environment by changing the microflora and their metabolite concentrations. In conclusion, continuous ingestion of yogurt may be effective way in alleviating IBS symptoms because gut microflora is one of the most important contributing factors in the development of IBS.

GAP 인증 인삼 마케팅전략에 관한연구

김관후 忠南大學校 大學院 2010 국내박사

Ginseng in Korea has not only the biggest production value but also still a good reputation from overseas in the name of 'Korea Ginseng'. Having spread rapidly nationwide from 2000 year, its production keeps on increasing but its consumption becomes lazy and its price is also falling down because of comsumer's concern about mainly overusing pesticide for ginseng. In order to cope with this problem, the government introduced the GAP certification system to ginseng in 2006 to reflect consumer's needs for food safety. This system will be a good opportunity to promote ginseng consumption dramatically. In this aspect it is very important to know how well this system is established and how ginseng farmers build marketing strategies to draw new wind in the market. This study was carried out to look over the GAP certified ginseng system and show its marketing strategies using STP(segmentation, targeting, and positioning) and 4P‘s(product, place, promotion and price). The main results are as follows. 1. GAP ginseng system currently has some weaknesses such as lack of systematic certification management and after-service, nonrealistic certification fee and poor linkage from production to consumption. And GAP ginseng requires 3.2% higher production cost than general ginseng. 2. Consumers' willingness to pay(WTP) for GAP ginseng was 7,477 won per 750g, which consist of 34% of its selling price. And retailers' WTP was 4,349 won for self-sufficiency and 6,779 won for present. 3. As a result of market segmentation, 3 consumer groups(large size preferred, safety preferred, lower price preferred) were classified. Among those groups, the safety preferred group was selected as a target market for GAP ginseng and its market size was estimated approximately 6,038 tons which is 26.8% of total ginseng market. And it is better to choose multi benefit positioning which appeals to consumers as 'safe, credible but less expensive product'. 4. In the marketing mix strategies, product strategy suggests that the most desirable appearance be transplanted ginseng filled with branch roots and 4 to 5 year-ginseng, and it is necessary to choose multi-brand strategy divided for present into for self-sufficiency and family brand strategy by use if its brand enlarges to processed products in the future. 5. In the place strategy, 3 stages like 'producer group' - 'GAP certified facility' - 'sales shop' are based as the physical marketing channel according to traceability, and connected with giant retail market and environment friendly stand, and if its sales volume enlarges, it should be considered the GAP ginseng specialized marketplace which is a type of chain store. 6. In the promotion strategy, the promotion of government level is necessary at first and producer alliances require the promotion targeting at the group of women under 40 with differentiation from price, quality, and safety. 7. In the price strategy, the early stage-high price strategy which sets 20~25% higher for self-sufficiency and 30~35% for present is desirable. In conclusion, it was proved that the GAP ginseng has a room enough to gain consumer's preference and much higher willingness to pay(WTP) than conventional ginseng. Therefore this study indicates that the GAP certified ginseng system should be promoted to not only consumers but also producers and middlemen for well-established starting point.

Recently, e-commerce, a type of digital economy is rising up as a new marketing method of agricultural products. This study was focused on analyzing the impacts of e-commerce on the farmer's management behavior and identifying alternatives for the development of e-commerce in agricultural industry. For this study, survey was conducted for 24 farmers who sell their products through e-commerce in Chungchungnam-Do province. The results of 4 aspects are as follows. 1. Farmer's decision-making system : The surveyed farmers changed their mind to set up the production system appropriate for e-commerce or to use consumer informations aggressively. 2. Marketing structure : The farmers made a brand of their product to get various effects such as product discrimination, building up consumer trust etc. The amount of line shipping through co-op tended to be reduced as a result of increasing the e-commerce. It was necessary for 2~3 years to enter the e-commerce market of agricultural products. 3. Production structure : The farmers introduced a quality certification system and changed as their crops suitable for e-commerce. Even though a beginner stage, e-commerce influenced all of the production system. 4. Management structure : 75% of the farmers sold their product at retail price. It means that the e-commerce farmers act as a price maker in the market. And also they increased their business size through introducing processing facilities, and acquired the add value from them. As a final result, e-commerce of agricultural products has a lot of impacts especially on the area of farm production as well as on the consumer market. For developing the e-commerce of agricultural products, we suggest some alternatives such as the improvement of financial environment through the reducement of a service charge of card, the increasement of B2B transaction in the economy of scale by farmer's partnership or corporate and the introduction of quality certification system for agricultural products.

기존 로봇 팔은 고정된 위치에서 지정된 물체에 대해서만 작업하여 활용처가 제한되었었다. 이를 개선하기 위해 이동 로봇에 로봇 팔을 장착 시키고, 다양한 크기의 물체에 대해서도 작업할 수 있도록 테스트를 진행하였다. 하지만 로봇 팔로 물체 집어 올릴 때, 물체의 무게 중심 등을 고려하여 물체를 집지 못해 물건을 놓치는 경우가 발생하였고 문제를 해결하기 위한 연구가 진행되었다. 연구는 이미지상 물체의 꼭짓점 좌표를 획득한다면, Depth 카메라로 사각형 물체에 대한 실제 길이 및 체적 추론 시스템을 설계해보고 검증해보는 것으로 진행되었다. 설계 시스템의 체적 추론 정확도는 오차범위 ±15%로, 추후 시스템을 보완한다면 로봇 팔에만 적용하는 것이 아닌 스마트 공장 등 다양한 분야의 시스템에 활용할 수 있을 것이라 기대된다. Currently, the robot arm has only operated on a designated object in a fixed position. In order to increase the various usability of the robot arm, the system was implemented so that the robot arm can be mounted on the mobile robot and worked on objects of various sizes. However, there was no information on the actual length and volume of the object to be picked up, causing instability or missing when working on the robot arm. To compensate for this, we designed and verified a system that infers the actual length and volume of objects such as boxes with a Depth camera. The volumetric inference error range of the designed system is ±15% and will be improved to complement the accuracy and make the Depth camera placement more convenient in future studies. It is expected that the designed actual box length and volume inference system can be used in various fields such as smart factories as well as robot arms.
