Recently, web services have been expanded to various areas with the evolution of cloud environment. Whenever a user accesses a web service, the user's log information is stored in the web server. This log information is used as data to analyze the user's web service tendencies and is also used as important data to track the user's system access when a security problem in the system occurs. Currently, most web servers manage user log information in a centralized manner. When user log information is managed in a centralized manner, it is simple in the side of operation, but has a disadvantage of being very vulnerable to external malicious attacks. In the case of centralized management, user log information stored in the web server can be arbitrarily manipulated by external attacks, and in severe cases, the manipulated information can be leaked. In this case, it not only decreases the trust of the web service, but also makes it difficult to trace the source and cause of the attack on the web server. In order to solve these problems, this paper proposes a new method of managing user log information in a cloud environment by applying blockchain technology as an alternative to the existing centralized log management method. The proposed method can manage log information safely from external attacks because user log information is distributed and stored in blockchain on a private network with cloud environment.
This study has examined the effect of cognitive resource on purchase intention of scarcity products according to the level of need for cognitive closure. In order to find out the effect on purchase intention for products that are presented a shopping environment is supposed, where various timing of consumer promotion reward exist, and where consumers can easily access and experience a lot of cognitive changes. the effect of how these two influences are adjusted according to the level of need for cognitive closure (NFCC). The study divide into two experiments. Research analyzes the behavioral differences of consumers for scarcity message products according to cognitive resource level with a moderating effect of NFCC. As a result of the study, Research according to the level of cognitive resource, when applied scarcity message product showed a negative effect of the cognitive resource (self-regulating resource) depletion level on the purchase intention of high-involvement product with scarcity message (Hypothesis 1). Consumers' purchase intention for limited products was higher at the non-depleted level than at the cognitive resource depletion level, and this difference was found statistically significant. Next, as a result of examining the difference according to the level of NFCC, the difference in the influence of cognitive resource level on purchase intention of scarcity products was found to be statistically significant where the NFCC was low (Hypothesis 2).

This exploratory study which applied environmental scanning method to analyse a change in a future society tried to diagnose a reaction ability of our education system for the change in the future society. In addition, the study tried to explore an adequate direction for Home Economics Subject to be an mandatory subject continuously toward the change in the future society. Main changes in the future society can be expected as 1) demographic change due to low birth rate and aging society, 2) an increasing threat of a human living environment due to unexpectable natural disasters and accidents, 3) a radical progress into a ubiquitous computing environment led by AI, 4) an advent of a borderless economic society and a change for jobs, 5) a change in North Korea, and so on. Our education system which mostly concentrates on education to develop constructive intelligence by halving the society and schooling as yet, however, is diagnosed as it has a paradox that can not understand an emotional competency as a target for studying. Home Economics Subject is worth as the subject that can exactly complement a blind spot of our education system which can not respond to the future society adequately. This is because Home Economics Subject has had a characteristic as a 'Subject of Life' traditionally that has dealt with an overall 'life' of human beings, and the characteristic is favorable to develop human practical intelligence. Thus, because the 'life' is the main point of Home Economics Subject, it has the characteristic as a 'Subject of Happiness' which is the most effective method to develop a tendency to appreciate, a sense of empathy, and lots of pro-social behaviors that are important capacities to seek for happiness. As Alderfer's ERG Theory is to understand human beings' behavior based on the satisfactory of human beings' hierarchical desires, it is suggested as an adequate frame for the theory to restructure the characteristic of Home Economics Subject which develops the 'capacity to seek for happiness' by focusing the 'life', into core concept and core capacity of curriculum. A follow-up study should make a connection between ERG Theory and core concept and core capacity of curriculum to explore how the theory can be reflected on Home Economics curriculum.
This study is a study to examine and verify the importance of human resources among the various factors that modern companies need to consider in order to cope with the changing environment. As independent variables, acquiescent and defensive silence were composed of the motives felt by members, and creativity and innovation behavior were set as the outcome variables. Through this research, first, the importance of communication between the members of the organization and the manager is investigated, and it is intended to be managed efficiently. Secondly, we would like to confirm the modulating effect of resilience in the relationship between them, and to find out the importance of psychological recovery of members. In the end, this aims to talk about the importance of psychological management and recovery of members in managing human resources. As a result, acquiescent silence negatively affects creativity and innovation behavior, and defensive silence positively affects creativity and innovation behavior. In addition, in the case of the moderating effect of resilience, there was no significant relationship in both defensive silence, creativity, and innovation behavior, and in the case of acquiescent silence, only innovation behavior was found to be significant. This is the result of the combination of the unique characteristics of resilience and the difference in the disposition of the members who choose resignation silence and defensive silence.
Smart Factory is different from existing factory automation in that it aims to produce personalized products with minimum time and cost through ICT. However, previous researches, not from consumers but from product suppliers, have focused on technology trends and technology application methods. In order for Smart Factory to be successful, it must go beyond supplier-focus to meet the needs of consumers. In this study, we surveyed the purchase intention of the personalized product manufactured by smart factory. Influencing factors of purchase intention were drawn as consumers' need for uniqueness, innovativeness, need for touch, and privacy concern, based on previous research. As results of data analysis, it was confirmed that respondents were willing to purchase personalized products, and that consumers' need for uniqueness, innovativeness, and need for touch had a significant impact on purchase intention of personalized products. Our findings can be summarized as follows. First, Consumers' need for uniqueness was found to have positive effects(${\beta}=0.168$) on purchase intention of personalized products. The desire to differentiate themselves from others will be reflected in their personalized products. Therefore, consumers with a higher desire for uniqueness tend to be more willing to purchase personalized products. Second, consumer innovativeness was found to have positive effects(${\beta}=0.233$) on purchase intention of personalized products. Personalized shoes suggested in this study is a new type of personalized product that is manufactured by the latest information and communication technologies such as multi-function robots and 3D printing. Therefore, consumers seeking innovative new experiences are more willing to purchase personalized products. Third, need for touch was found to have positive effects(${\beta}=0.299$) on purchase intention of personalized products. In a smart factory environment, prosuming participation is given to consumers. If consumers participate in the product development process and reflect their requirements on the product, they are expected to increase their purchase intention by virtually satisfying the need for touch. Fourth, privacy concern was found to have no significantly related to purchase intention of personalized products. This is interpreted as a willingness to tolerate the risk of exposing personal information such as home address, telephone number, body size, and preference for consumers who feel highly useful in personalized products.

Upon development of information super-highway and multimedia-related technoiogies in recent years, more efficient technologies to transmit, store and retrieve the multimedia data are required. Among such technologies, firstly, it is common that the semantic-based image retrieval is annotated separately in order to give certain meanings to the image data and the low-level property information that include information about color, texture, and shape Despite the fact that the semantic-based information retrieval has been made by utilizing such vocabulary dictionary as the key words that given, however it brings about a problem that has not yet freed from the limit of the existing keyword-based text information retrieval. The second problem is that it reveals a decreased retrieval performance in the content-based image retrieval system, and is difficult to separate the object from the image that has complex background, and also is difficult to extract an area due to excessive division of those regions. Further, it is difficult to separate the objects from the image that possesses multiple objects in complex scene. To solve the problems, in this paper, I established a content-based retrieval system that can be processed in 5 different steps. The most critical process of those 5 steps is that among RGB images, the one that has the largest and the smallest background are to be extracted. Particularly. I propose the method that extracts the subject as well as the background by using an Image, which has the largest background. Also, to solve the second problem, I propose the method in which multiple objects are separated using RGB channel selection techniques having optimized the excessive division of area by utilizing Watermerge's threshold value with the object separation using the method of RGB channels separation. The tests proved that the methods proposed by me were superior to the existing methods in terms of retrieval performances insomuch as to replace those methods that developed for the purpose of retrieving those complex objects that used to be difficult to retrieve up until now.

Currently while a phase of the Internet as an advertising media is firm, and Internet advertisement utilization of a company rises, and the consumers contact with various Internet advertisements. A lot of Internet advertisements of various forms made with new technology to develop rapidly are executed and will disappear again. Now, It is necessary to classify various types of the Internal advertisement which was made by a sharp environment change, and was tested of the last ten years and to classify expression techniques systematically. At the same time, we have to check a development direction of domestic Internet advertisement and trend. It is a point of time that Internet advertisement must be designed in a macroscopic dimension like the four medium advertisement by an advertisement strategy and an expression strategy. In this paper, first I classified a type of domestic Internet advertising into marketing, an advertisement purpose, an expression form, manufacture technology, and an express on method systematically in five sides so far And I tried to consider the form and characteristics. By next time, while examine change of internet marketing paradigm, I checked trend of recently domestic Internet advertising in accord to a change of consumer's use tendency and a change of Internet advertisement manufacture technology, and tried to consider the development course in the marketing side, the manufacture technical side, and the creative side. Finally, I wish to propose necessity of expression strategy establishment to promote development of the interactive advertisement technique that considered the creative side in order to raise an effect of Internet advertisement.
In Korea, it is significantly deficient in the study about tourism geology, which is a new branch of applied geology that would support the growth of ecotourism world-wide. The objectives of this study include (1) the promotion in geodiversity of tourism geology using the data for type and distribution patterns of geological and geomorphological landscape resources and (2) the redoubling of diversity in the environmental interpretation programs offered by the Korea National Parks Service (KNPS). Our field study discovered 212 geological and geomorphological landscape resources distributed in the area of Taean seashore national park. Coastal topography is the most discovered type followed by weathering topography. It is our belief that the aforementioned resources can be utilized as a tourism geological site in assisting the public to understand geological science and to draw their attention and interests after sorting and filtering it out through discussions with geologists and geomorphologists of a consortium. Furthermore, in order to promote the activation of developing user-oriented geotourism sites, it is recommended to keep monitoring on demographical characteristics of geotourists, behavioral characteristics of geotouconrists within the geotourism site and ducting analysis for developing geotourism program and events. And, the research support of geological engineering dealing with the estimation of weathering degree and the development of conservation techniques for the object of geotourism along with the research of environmental science aspects will improve the activation of tourism geology.
