The O2O store model dissolves the boundaries between online and offline platforms, providing significant convenience to customers. To effectively operate such platforms, small business owners must provide necessary information in digital format. Specifically, the process of digitizing Korean menus manually can lead to multiple issues, and the use of OCR technology often results in high error rates due to the low accuracy in recognizing Korean. In response, this paper proposes an enhanced OCR model based on the popular EasyOCR framework, aimed at improving the recognition accuracy of Korean. The proposed model integrates the structural advantages of VGG and ResNet, and incorporates an attention mechanism to significantly improve the recognition performance of Korean. Moreover, experimental results indicate that the proposed model achieved approximately a 3.5% improvement in accuracy and around a 1% improvement in both confidence score and normalized edit distance compared to EasyOCR. Therefore, this demonstrates that the proposed method effectively addresses the existing challenges.

This study investigated consumers' enjoyment, perceived risks, expected values, and innovativeness factors and the effects of the convenience and personalization of "online to offline" (O2O) fashion mobile commerce on its perceived usefulness, perceived ease of use, and consumers' attitudes and intention to use O2O mobile commerce. A research model was developed using the Technology Acceptance Model (TAM). A mobile survey was conducted through smartphone messengers and SNSs targeting male and female college students in their 20s who are living in the Seoul Metropolitan Area. A total of 192 questionnaire responses were used in the analysis. "Among the consumer characteristics, only enjoyment and expected values were found to make consumers feel that the O2O fashion mobile commerce is useful and easy to use. Among the mobile commerce characteristics, only convenience was found to have significant effects on consumers' perceived usefulness and ease of use regarding O2O fashion mobile commerce. Perceived usefulness was found to have the effects on attitudes as well as intention to use toward O2O mobile commerce. It was shown that positive attitudes toward O2O mobile commerce led to positive use intention toward O2O mobile commerce.

본 연구는 모바일 쇼핑의 급증과 더불어 성장하고 있는 O2O(Online-to-Offline) 시장에서 소비자가 추구하는 쇼핑가치(shopping values)를 충족시켜줄 수 있는 웹사이트를 구축하기 위한 요인들을 탐색함으로써 이들 쇼핑가치와 웹사이트 성공요인 간 관계가 향후 소비자의 재구매의도와 같은 고객충성도에 미치는 영향을 고찰하는 데에 그 목적이 있다. O2O 시장에서는 온라인 웹사이트로 소비자를 유도하여 필요한 정보를 제공한 후 관련 제품과 서비스를 수령할 때에는 다시 오프라인으로 유도함으로써 잠재 고객을 확대하고 기존 소비자의 구매를 확대시키고자 한다. 따라서 소비자가 제품과 서비스를 접하는 첫 관문인 웹사이트 설계는 중요한 고려대상이다. 기존 B2C(Business-to-Consumer) 환경에서는 온라인과 오프라인이 각각 독립적인 채널로 운영된 데에 반해 O2O 환경에서는 온라인과 오프라인의 통합으로 시너지 효과를 추구하기 때문에 O2O 채널을 이용하는 소비자가 추구하는 쇼핑가치는 기존 B2C와 다르며 본 연구에서는 새로운 O2O 환경에서 이러한 소비자의 쇼핑가치를 충족시켜줄 수 있는 성공적인 웹사이트 요인을 탐색하고자 한다.

The global medical tourism industry including Asian market has been activating recently. That is as medical tourists are motivated to seek the higher quality of healthcare with lower costs, as well as of travel. The consumers in this field tend to need customized services of medical tourism. It is needed that the consumers get customized information on medical services and traveling, the clinics and hospitals resolve the issues of offering translation and luring medical tourists from overseas, and the guides, who offer tour and translation service, provide the consumers and the clinics with customized services so that they get the services needed for one another. This research studies the Offline to Online, called O2O, matching platform based on global clinics, which connects medical facilities, patients, and guides for traveling and language services. It presents the customized marketing plans by utilizing customers' experiences from medical services and traveling they use.

Although offline enrichment of phosphorylated peptides is widely used, enrichment for phosphopeptides using $TiO_2$ is often performed manually, which is labor-intensive and can lead to irreproducible results. To address the problems associated with offline enrichment and to improve the effectiveness of phosphopeptide detection, we developed an automated online enrichment system for phosphopeptide analysis. A standard protein mixture comprising BSA, fetuin, crystalline, ${\alpha}$-casein and ${\beta}$-casein, and ovalbumin was assessed using our new system. Our multidimensional system has four main parts: a sample pump, a 20-mm $TiO_2$-based column, a weak anion-exchange, and a strong cation-exchange (2:1 WAX:SCX) separation column with LC/MS. Phosphorylated peptides were successfully detected using the $TiO_2$-based online system with little interference from nonphosphorylated peptides. Our results confirmed that our online enrichment system is a simple and efficient method for detecting phosphorylated peptides.

2015년 대한민국을 관통하는 키워드 중 하나가 O2O (Online to Offline)이다. 대기업과 중소기업까지 O2O를 전면에 내세우고 새로운 비즈니스를 모색하는 기업들이 확대되고 있다. O2O 비즈니스 기업들의 업종도 모바일 메신저, 포털을 비롯한 인터넷 사업자, 통신사업자, 모바일 기기 제조사, 전자상거래 기업과 같은 정보통신기술(ICT) 관련 기업부터 유통기업까지 다양하다. 본 연구를 위하여 2014.5~2015.5 1년 간 여자대학생 92명의 '모바일 쇼핑 금융서비스 이용 현황' 조사를 실시하였다. 조사 결과, 상품정보검색(96.7%), 구매(88%), 주문 배송(77.2%), 할인 프로모션정보(62%) 등 모바일 쇼핑을 하였고, 모바일금융 서비스로는 하루에 1번정도 (20.4%), 월1~3회(20.4%), 1주 3~4회(16.3%), 이용 안하는 경우(24.5%)로 조사 되었다. 모바일 금융서비스를 이용하지 못하는 이유로는 개인정보보안 및 해킹우려(39%), 이용/결제 과정의 불편함(25.8%) 등 이었으며, 국내 O2O 플랫폼이 제공하는 서비스는 쇼핑부터 결제까지 완결적인 구조로 보완할 부분이 필수적이다.

In order to provide personalized services on the Web and for mobile services, it is necessary to collect and analyze information processed by users. Typically, information collected by users is managed online. Using information collected online may be sufficient to provide personalized service. However, in terms of O2O services, which are currently mixed with online and offline services, user information from the offline service can also be an important part of personalized service. Therefore, this study suggests an architecture to collect offline user information to provide more precise personalization services. The collection architecture includes Node Analyzer, Distance Checker, Holding Time Checker, and Cross Analyzer as core elements. This study also offers proposals for processing algorithms of key components that make up the proposed architecture. A case study collects user information of interest based on BLE in order to verify the proposed architecture and algorithms.

The rapid advancement of digital technology and the COVID-19 pandemic have significantly accelerated the growth of online commerce, highlighting the need for support mechanisms that enable small business owners to effectively respond to these market changes. In response, this paper presents a foundational technology leveraging the Online to Offline (O2O) strategy to automatically capture products displayed on retail shelves and utilize these images to create virtual stores. The essence of this research lies in precisely identifying and recognizing the location and names of displayed products, for which a single-class-targeted, lightweight model based on YOLOv8, named ESD-YOLOv8, is proposed. The detected products are identified by their names through feature-point-based technology, equipped with the capability to swiftly update the system by simply adding photos of new products. Through experiments, product name recognition demonstrated an accuracy of 74.0%, and position detection achieved a performance with an F2-Score of 92.8% using only 0.3M parameters. These results confirm that the proposed method possesses high performance and optimized efficiency.
