웹은 이미 인터넷 사용에 있어 가장 중요하고, 자주 이용하는 서비스로 자리 잡고 있으며, 이에 대한 여러 활용 방안에 대해서도 많은 연구가 진행되었다. 그럼에도 불구하고 웹을 이용한 메시지 전달이나 광고 등은 서비스를 제공하는 포털에 의해서 진행되고 있고, 해당 포털에 접속하지 않은 사용자에게 원하는 메시지를 전달하기가 어려운 것이 현실이다. 이미 긴급 재난 공지 등은 각 포털의 공지사항 등을 이용하여 전달하고자 하는 시스템을 구축하고 있지만 이는 결국 해당 포털에 접속해야만 메시지를 볼 수 있으며. 각 포털에 메시지를 전파하고 협조를 얻어야 하는 등의 문제가 있다. 또한 지역적, 국지적으로 발생하는 사안이나 긴급을 요하는 메시지의 경우 이러한 방식이 맞지 않고, TV, 방송 등의 직접적인 수단을 통해서만 메시지를 전달할 수밖에 없으며, 대부분의 많은 메시지가 이런 식으로만 전달하기엔 적합하지 않은 현실에 비추어 볼 때 그다지 효율적이라 볼 수 없다. 이에 7계층의 컨텐츠 스위칭 기법에서 사용되는 방식을 이용하여 네트워크의 중간에서 직접 사용자별 혹은 목적지 별 메시지를 사용자가 접속하려는 사이트나 해당 컨텐츠의 저작권과 관계없이 메시지를 전달하는 방안을 제안하고자 한다.

This study is to contribute to the policy decision of cosmetic industry through analyzing marketing mix factors which affects customers' buying intention. For this study, marketing mix factors that impact on cosmetic customers purchasing intention were collected and chi-square independence analysis of SPSS and qualitative analysis technology of Kano & Timko were used. Analysis reached one conclusion, which factors were maximizing customers satisfaction, shows the price discount policy and recommendation from family and colleague. Product's effectiveness, usefulness and skin compatibility were rated as an one-dimensional quality as those factors were linearly affected when customers needs were satisfied. However product's containers, package design, colors, brand reputation, low and middle price, distribution channel and advertising medias were investigated as an indifferent quality and they were rated as low satisfaction/dissatisfaction coefficient of Timko. Therefore they do not need to invest to those factors too much budget for attaining customers' buying intention.

The synthesis of 1-[2-(3-{7-oxabicyclo[4.1.0]heptyl} 1,1,3,3-tetramethyl-disiloxane (Mono), which is a key intermediate for the synthesis of monomers applied for photopolymer systems based on the cationic ring opening polymerization, was studied. Mono was successfully synthesized by the hydrosilylation reaction of 4-vinyl-1-cyclohexene 1,2-epoxide (VCHO) with an excess amount of 1,1,3,3-tetramethyldisiloxane (TMDS) in the presence of a Speier catalyst. The structure and the purity of Mono were characterized by FT-IR, $^1H-NMR$, and $^{29}Si-NMR$. The optimum conditions for the hydrosilyation reaction were found to be 1:4 molar ratio of VCHO to TMDS and 5 ppm of the catalyst at the temperature of $55^{\circ}C$.

In this paper, we present a real-time hand pose recognition method to provide an intuitive user interface through hand poses or movements without a keyboard and a mouse. For this, the areas of right and left hands are segmented from the depth camera image, and noise removal is performed. Then, the rotation angle and the centroid point of each hand area are calculated. Subsequently, a circle is expanded at regular intervals from a centroid point of the hand to detect joint points and end points of the finger by obtaining the midway points of the hand boundary crossing. Lastly, the matching between the hand information calculated previously and the hand model of previous frame is performed, and the hand model is recognized to update the hand model for the next frame. This method enables users to predict the hidden fingers through the hand model information of the previous frame using temporal coherence in consecutive frames. As a result of the experiment on various hand poses with the hidden fingers using both hands, the accuracy showed over 95% and the performance indicated over 32 fps. The proposed method can be used as a contactless input interface in presentation, advertisement, education, and game applications.

The specific gravity is heavily focused on the service industry in the economic development of domestic and overseas in these days. This will be predicted to increase persistently in the future society. Therefore the franchise system has been diffused as one of a management methods for these service industry. The franchise system is an advanced country's circulation system which has been populated in an advanced country. After the opening of circulation market, rapid growing trend has been showing on foreign country's popular brands in the local domestic market. So the franchise system has been largely focused on among the domestic manufacturing and the circulation companies. This study is to review how the management characteristics(headquarters' supports, communication, menu development, compensation) will affect the fairness perception of franchisee owner. The results of my study are as follows; It appeared that communication, menu development and compensation affected all the distribution fairness and the procedure fairness affirmatively.

Online transactions are more familiar in various fields due to the development of the ICT and the increase in trading platforms. In particular, the amount of transactions is increasing due to the increase in used transaction platforms and users, and reliability is very important due to the nature of used transactions. Among them, the used car market is very active because automobiles are operated over a long period of time. However, used car transactions are a representative market to which information asymmetry is applied. In this paper presents a DID-based transaction model that guarantees reliability to solve problems with false advertisements and false sales in used car transactions. In the used car transaction model, sellers only register data issued by the issuing agency to prevent false sales at the time of initial sales registration. It is authenticated with DID Auth in the issuance process, it is safe from attacks such as sniping and middleman attacks. In the presented transaction model, integrity is verified with VP's Proof item to increase reliability and solve information asymmetry. Also, through direct transactions between buyers and sellers, there is no third-party intervention, which has the effect of reducing fees.

The desire for clear and clean skin is universal among both men and women. Women, in particular, seek the help of foundation to achieve beautiful and transparent skin. The choice of foundation is not determined by the race of an individual; instead, it varies based on personal skin color and undertone. Therefore, there is a need to surpass the stereotype of using foundation colors based on racial discrimination. The purpose of this study is to randomly select cosmetics brands from Korea, China, Japan, the United States, France, and the United Kingdom, considering the impact of each photo, environment, and equipment. The objective is to understand the differences in skin tones in foundation advertisement model images on websites. Analyzing the RGB values of foundation colors for each brand revealed that in Korea, the colors were 8.75R, 1.25YR, 2.5YR, 3.75YR, 5YR, and 6.25YR. Chinese brands showed similar colors with 2.5YR, 3.75YR, 5YR, 6.25YR, and 10YR. Japanese brands displayed colors such as 7.5R, 8.75R, 10R, 5YR, 6.25YR, and 7.5YR. American brands presented colors like 6.25R, 8.75R, 10R, 2.5YR, 3.75YR, 5YR, 6.25YR, 7.5YR, and 10YR. French brands featured 10R, 1.25YR, 3.75YR, 5YR. Lastly, British brands displayed 2.5YR, 3.75YR, 7.5YR. As a follow-up study, in-depth research on the reshaping and color changes of foundation over time is recommended. It is hoped that this research will serve as fundamental data for makeup companies' marketing and contribute to the development of both domestic and international color cosmetics markets.

In Korea, from January 2023, the Act on Labeling and Advertising of Food was revised to reflect the use-by-date rather than the sell-by-date. Hence, the purpose of this study was to establish a system for calculating the safety factor and determining the recommended use-by-date for each food type, thereby providing a scientific basis for the recommended use-by-date labels. A safety factor calculation technique based on scientific principles was designed through literature review and simulation, and opinions were collected by conducting surveys and discussions including industry and academia, among others. The main considerations in this study were pH, Aw, sterilization, preservatives, packaging for storage improvement, storage temperature, and other external factors. A safety factor of 0.97 was exceptionally applied for frozen products and 1.0 for sterilized products. In addition, a between-sample error value of 0.08 was applied to factors related to product and experimental design. This study suggests that clearly providing a safe use-by-date will help reduce food waste and contribute to carbon neutrality.
