The Purpose: This study aims to identify the characteristics of customer satisfaction of the restaurants delivery applications that is increasing globally, especially in Korea. Due to demographic changes, social trends and the development of food science, customers no longer want to visit restaurants. This represents an important change in the restaurant business, and related research is also very urgent. Research design, data, and methodology: With 296 surveyed questionnaire, the study analyzed to verify the validity and reliability of measured variables in Korea. And structural equation model was used for hypotheses test of the research. Results: The result showed that consumers' usefulness, mobility, and reliability influenced on satisfaction. Specifically, mobility and reliability influencing the satisfaction and loyalty as well. And significant impact of satisfaction and loyalty are also corroborated. However, the path from informative to both satisfaction and loyalty was not statistically significant. This means food application developers should no longer focus on providing too many information, instead, concentrate on improving mobility and trust of mobile applications. Conclusions: This study analyzed the influence of attributes of food delivery applications on satisfaction and loyalty, and suggested crucial strategic implications of delivery marketing companies involved in the implementation of mobile application developers.

As current postal automation is limited to dispatch and arrival sorting, delivery sequence sorting is performed manually by each postman. It not only acts as a bottleneck process in the overall mailing process but is expensive operation. To cope with this problem effectively, delivery sequence sorting automation is required. The important components of delivery sequence sorting automation system are sequence sorter and Hangul OCR which function is to extract the address of delivery point. DSI database will be interfaced to both Hangul OCR and sequence sorter for finding the accurate delivery sequence number and stacker number. The objectives of this research are to develop DSI(Delivery Sequence Information) database prototype and client application for managing information effectively. For database requirements collection and analysis, we draw all possible sorting plans, and apply the AHP(Analytic Hierarchy Process) method to determine the optimal one. And then, we design DSI database schema based on the optimal one and implement it using Oracle RDBMS. In addition, as address information in DIS database consist of hierarchical structure which has its correspondence sequence number, so it is important to reorganize sequence information accurately when address information is inserted, deleted or updated. To increase delivery accuracy, we reflect this point in writing application.

선행된 연구에서 Yo-Pro-1의 전달 효율의 경향과 CFP 유전자의 발현 효율의 경향이 큰 차이를 보였지만 이 문제에 대한 원인을 제시할 수 없었다. 따라서 본 연구에서는 형광 염료를 이용하여 DNA에 표지 후 전달 효율을 정량화함으로써 이 문제에 대한 원인을 찾고자 한다. 표지를 위한 형광 염료로 Yo-Pro-1을 사용하였으며, Yo-Pro-1과 표지 된 DNA의 전달 효율을 비교하였다. 전압 조건에 따른 전달효율 비교에서는 Yo-Pro-1과 Yo-Pro-1으로 표지 된 DNA의 전달 효율 모두 96 V에서 전달 효율이 최대가 되었으며 전압이 더 증가하면 전달 효율이 오히려 감소하는 경향을 보였다. 전압 인가 횟수 조건에 따른 전달 효율 비교에서는 Yo-Pro-1과 Yo-Pro-1으로 표지 된 DNA의 두 전달 물질 모두 8회의 전압 인가 횟수에서 전달 효율이 최대가 되었으며 전압 인가 횟수가 더 증가하면 전달 효율이 감소하는 경향을 보였다. 두 결과를 통해 디지털 전기천공시스템에서 Yo-Pro-1을 사용한 전달 효율 측정이 DNA의 전달 효율을 잘 대변하는 것을 확인하였다. 또한, 본 연구의 결과를 통해 선행된 연구에서 보인 Yo-Pro-1의 전달 효율의 경향과 CFP 유전자의 발현 효율의 경향 차이는 전달 물질의 전달 효율 차이에서 기인한 결과가 아닌 전달 된 유전 물질의 발현 과정에서의 문제로 인한 결과임을 추론해 볼 수 있었다.

Milk proteins, such as casein and whey protein, exhibit significant potential as natural emulsifiers for the preparation and stabilization of emulsion-based delivery systems. This can be attributed to their unique functional properties, such as the amphiphilic nature, GRAS (generally recognized as safe) status, high nutritional value, and viscoelastic film-forming ability around oil droplets. In addition, milk protein has been used as a coating material in emulsion-based delivery systems to protect bioactive compounds during food processing and storage owing to its unique functional properties. These properties include the ability to bind lipophilic bioactive compounds and antioxidant activity. In this review, we present the use of milk proteins as emulsifiers for the formation of emulsions and food applications of milk protein-stabilized emulsion delivery systems.

The aim of this study was to determine if a meloxicam hydrogel could be administered in vivo via phonophoretic transdermal delivery using pulsed ultrasound by examining its anti-hyperalgesic effects in a rat carrageenan inflammation model. Carrageenan (1%) was injected into the plantar surface of the right hindpaw, and meloxicam hydrogel was administered via phonophoretic transdermal delivery. Changes in the mechanical and thermal hyperalgesia, as well as swelling, showed that phonophoretic delivery of meloxicam exhibited significantly better anti-hyperalgesic and anti-inflammatory effects than pulsed ultrasound. Topical and systemic application of meloxicam hydrogel using phonophoresis showed similar anti-hyperalgesic effects. These findings suggest that the transdermal administration of a meloxicam hydrogel using phonophoresis by pulsed ultrasound might be useful for treating acute inflammation.

In order to develop an optimum formulation for iontophoretic flux of vitamine C 2-phosphate (VCP), we have prepared three different hydrogels containing VCP, using carbopol, HPMC and poloxamer, and iontophoretic flux through hairless mouse skin from these hydrogels was carried out. Drug stability in phosphate buffer (PBS) solution (pH 7.4) with and without current application was studied. The effect of various factors, such as drug concentration, current density, and current profile on skin flux was also investigated. Stability study indicated that VCP in PBS (pH 7.4) solution was stable under the experimental condition, irrespective of the presence of current. Cathodal delivery increased the flux markedly, whereas the anodal and passive flux was negligible. Thus, cathodal delivery was used in all experiments. Flux increased as the drug concentration (2.5, 5.0, 7.5%) and current density $(0.2,\;0.4,\;0.6\;mA/cm^2)$ increased. Pulsed application of the current showed lower flux than constant current application. The results obtained suggest that VCP can be delivered into the skin and the amount delivered can be controlled by varying hydrogel, current density, drug concentration and current application profile.
