Recently, in Korea, financial institutions such as banks are most severely affected by the universalization of the Internet and smartphones. On the other hand, the use of online systems by financial institutions keeps increasing; the convenience of online services has a significant influence on the attraction and the retention of financial customers; consumer needs are also diversely expressed. This paper deduces from the precedent researches a mechanism that online financial system enhances the trust of customers -the medium of the online system and other customers- and its perceived easiness affects its perceived effectiveness and then all these internal variables induce satisfaction. Plus, this paper aims at verification of the hypothesis in terms of an extended technology acceptance model, based on the hypothesis that word of mouth and repurchase are significantly linked to this mechanism. Through this study, the researchers tried to check how the online service quality and emotional factors of financial institutions affect the users in accordance with the trend of changes in the service usage method of financial institutions, and confirmed that the hypothesis was not rejected.

Due to the recent COVID 19 pandemic, public institutions are increasingly working from home. Working in public institutions is rapidly changing into a smart work environment where time and space constraints disappear. However, many public institutions currently lack a security model for an efficient smart work environment due to the physical network separation system that separates the Internet network and the business network. Therefore, in this paper, we describe the current limitations for implementing smart work in a physical network separation environment of public institutions, and propose a security model necessary for a work environment to supplement them. As a related study, explain SSL VPN and explain smart work business model through security model research of SDP (Software Defined Perimeter), RDP (Remote Desktop Protocol), and VDI (Virtual Desktop Infrastructure) to overcome the security limitations of SSL VPN. As a result, we intend to propose a security model for a smart work environment suitable for public institutions while complying with the physical network separation security guide.

Home shopping is called the flower of future distribution. Among them, for TV home shopping, Korea should lead the industry as an advanced country in IT technology. It is difficult for small and medium businesses, however. This is due to the failure of the policies of Korea Communications Commission. In order to complement such policy failure, this study intends to analyze the preceding domestic studies and foreign status, and reflect such on the policy. Especially the domestic business will be predicted through foreign home shopping status and policy cases, and the items that should be supplemented with governmental policy in order to vitalize small & medium businesses were analyzed; these should be actively reflected by the government. In case of general PP, it already runs on the registration system, and the home shopping channel should also be the same and be committed to the market. The increased number of channels would allow a greater opportunity for small and medium businesses who are the suppliers, and for the consumers, the product prices would be able to be stabilized at an appropriate cost and high quality and diversity of items could be obtained through home shopping, thus improving consumer welfare. If it is difficult to adopt the registration system for home shopping right away, the best alternative is to strengthen the approval system. As home shopping requires a re-approval every 3 years, strengthened re-approval conditions would resolve part of the problem.

Korean government has taken positive policies, including making "An Basic Plan on the Conservation and Activation of the Royal Tombs of the Joseon Dynasty, UNESCO World Heritage", since 40 royal tombs of the Joseon Dynasty were inscribed as UNESCO World Heritage in 2009. However, projects utilizing the royal tombs of the Joseon Dynasty are in the beginning step and very few has been researched on those projects academically. This study analyzed total 311 projects utilizing the royal tombs of the Joseon Dynasty, which have been made by the Cultural Heritage Administration of Korea from 2009 to 2014, through the literature review and content analysis methodology. An analysis frame consists of educational, touristic, compound and industrial activation on the basis of the utilization types made by the Cultural Heritage Administration of Korea. Most projects utilizing the royal tombs of the Joseon Dynasty are in the very beginning step in terms of educational and touristic utilization. No project utilizing the royal tombs of the Joseon Dynasty in terms of industrial utilization is found. Those projects are almost similar without distinctive characteristics peculiar to each royal tombs. Most projects have been taken on the short term level and the budget size for those is not enough. Projects are mostly focused on the on-site of royal tombs with little paying attention to converging projects utilizing digital and on line techniques. Some suggestions are the followings: increase of the budget on projects utilizing the royal tombs of the Joseon Dynasty, development of content peculiar to each tomb, development of industrial projects, development of converging projects utilizing digital and on line techniques, establishment of new medium and long term plans for utilization of the royal tombs of the Joseon Dynasty and so on.

Various devices are connected to the Internet, and attacks using the Internet are occurring. Among such attacks, there are attacks that use malicious URLs to make users access to wrong phishing sites or distribute malicious viruses. Therefore, how to detect such malicious URL attacks is one of the important security issues. Among recent deep learning technologies, neural networks are showing good performance in image recognition, speech recognition, and pattern recognition. This neural network can be applied to research that analyzes and detects patterns of malicious URL characteristics. In this paper, performance analysis according to various parameters was performed on a method of detecting malicious URLs using neural networks. In this paper, malicious URL detection performance was analyzed while changing the activation function, learning rate, and neural network structure. The experimental data was crawled by Alexa top 1 million and Whois to build the data, and the machine learning library used TensorFlow. As a result of the experiment, when the number of layers is 4, the learning rate is 0.005, and the number of nodes in each layer is 100, the accuracy of 97.8% and the f1 score of 92.94% are obtained.

The aim of this study is to protect workers and pedestrians from accidents at night or bad weather by attaching optical fiber to existing safety clothing that is made only with fluorescent fabrics and retroreflective materials. A safety vest was designed and manufactured by applying optical fiber, and energy-harvesting technology was developed. The safety vest was designed to emit light using the automatic flashing of optical fibers attached to the film, and an energy harvester was manufactured and attached to drive the light emission of the optical fiber more continuously. As a result, first, the vest wearer' body was recognized from a distance through the optical fiber and retroreflection, which helped prevent accidents. Thus, this concept helps in saving lives by preventing accidents during night-time work on the roadside or activities of rescue crew and sports activities, or by quickly finding the point of an accident with a signal that changes the optical fiber light emission. Second, to use the wasted energy, a piezoelectric-element power generation system was developed and the piezoelectric-harvesting device was mounted. Potentially, energy was efficiently produced by activating the effective charging amount of the battery part and charging it auxiliary. In the existing safety vest, detecting the person wearing the vest is almost impossible in the absence of ambient light. However, in this study, the wearer could be found within 100 m by the light emission from the safety vest even with no ambient light. Therefore, in this study, we will help in preventing and reducing accidents by developing smart safety clothing using optical fiber and energy harvester attached to save lives.

Museum is the carrier and symbol of history and cultural accumulation, and the museum cultural relics are clues with the spirit of history. Moreover, the museum cultural and creative products are portable history. Museum has changed form the traditional "object-basic" model to the modern "people-basic" model, which pays more attention to its living inheritance. Therefor, the museum cultural and creative products is also the way of expression of its living inheritance. This paper analyzes the opportunities and difficulties of cultural and creative products of Chinese museums by means of network survey, field survey and expert interview. In order to improve the design method of cultural and creative products. By exploring the cultural connotation, broadening the functional factors, innovating the design factors and creating the empathy factor between products and people to explore and the verify. Trying to make up the imperfect design methods of cultural and creative products in small and medium-sized museums which leads to the lack of function, innovation and communication of cultural and creative products. We try to attract more people's attention, spread traditional culture and realize the resonance between people and objects.

Together with the increase of public housing complex, the issues of community following residential environment under contemporary society has become an important issue and the collapse of traditional community has long been emerged as an important social issue. In order to facilitate communities within the public housing complex, various discussions have been continued, and for addressing such an issue under this study, the public housing complexes n Seoul, the capital region and other major cities have been surveyed and analyzed to draw following conclusion as the design-type study to propose a model of community facilities. It displays that there is certain limitation with respect to the diversity of programs when comparing the community facility standard defined under the public housing related laws and regulations. This is attributable to the fact that it is a limitation to satisfy the level of satisfaction for residents that expect the improvement in quality of leisure life, and the facility standard that is standardized around the physical facility environment has certain limitations to enhance the level of satisfaction for residents when the demand has been on the rise with respect to quality. For this fact, the approach in consideration of diversity for the facility standard has to be made in advance. As the utility of external space for the public housing is increased, it is reasonable to consider the plan to secure environment through the architectural factors, and it has the strength in enhancing the utility of internal and external space of the community facilities.
