The purpose of this study is to examine the relationship between the cell phone utilization and depression among the Korean elderly living alone using '2014 Korean National Survey on Older Adults. A total of 2,493 survey data of the elders living alone 65 years or more was included in the analysis. The degree of the cell phone utilization were categorized into (1) No cell phone, (2) Only phone calls, (3) Phone calls and text messages, and (4) Searching news and information through the internet surfing. The results showed that 81.5% elderly living alone had a cell phone. The 'no cell phone' group was 19.5% while 'information search' group was 3.5% among the elderly living alone and has more probability of depression than 'information search' group (OR=0.064, 95% CI=0.018-0.227), which indicates that as elders living alone utilize their cell phone more, the probability of the depression decreased. This result implies that elders living alone who utilize their cell phone more are engaged in social interaction more and this can lead to decrease in depression.

The amount of data is increasing through various IT devices in a hyper-connected society where the 4th revolution is progressing, and new value can be created by analyzing that data. This paper was collected total 1,526 articles from 2017 to 2019 in central magazines, economic magazines, regional associations, and major broadcasting companies with the keyword "(East Coast Tourism or East Coast Travel) and Gangwon-do" through Bigkinds. It was performed the topic modeling using LDA algorithm implemented in the R language to analyze the collected 1,526 articles. It was extracted keywords for each year from 2017 to 2019, and classified and compared keywords with high frequency for each year. It was setted the optimal number of topics to 8 using Log Likelihood and Perplexity, and then inferred 8 topics using the Gibbs Sampling method. The inferred topics were Gangneung and Beach, Goseong and Mt.Geumgang, KTX and Donghae-Bukbu line, weekend sea tour, Sokcho and Unification Observatory, Yangyang and Surfing, experience tour, and transportation network infra. The changes of articles on East coast tourism was was analyzed using the proportion of the inferred eight topics. As the result, the proportion of Unification Observatory and Mt. Geumgang showed no significant change, the proportion of KTX and experience tour increased, and the proportion of other topics decreased in 2018 compared to 2017. In 2019, the proportion of KTX and experience tour decreased, but the proportion of other topics showed no significant change.

Iching has been taught people wisdoms of Sijung since it appeared in oriental society thousands years ago. Sijung means each of us meets the change of the present situation reasonably and practices the timely truth. The current society we've been living is infra-structured by various kinds of visible or invisible networks. This society is called 'network society' which is characteristic of inter-connectivity, interactivity, and complexity, etc. This thesis is to study whether and how the wisdoms of Iching can be helpful for behaviors in network society. For this, the meaning of several hexagrams and the new paradigm of network society were reviewed. Then, which hexagrams give what wisdoms to individuals, organizations, and difficult situations in network society was discussed. In network society, individuals are surfing internet, meeting, chatting, and making groups to implement meaningful works. To these, some hexagrams give wisdoms such as the ethics of rightness, the virtue of the mean. Organizations in network society should rebuild and reform inner suborganizations, cooperate with other organizations including citizen alliances, competing firms, and government organs. To these, some hexagrams give wisdoms such as faithfulness, considerateness, and completeness. Other hexagrams give also wisdoms such as neighborhood, non-selfishness, and self-discipline, to difficult situations lack in communication in network society.

Recent advances in mobile devices and development of various mobile applications dealing with private information of users made user authentication in mobile devices a very important issue. This paper presents a new user authentication method based on touch screen interfaces. This method uses for authentication the PIN digits as well as the exact locations the user touches to input these digits. Our method is fully compatible with the regular PIN entry method which uses numeric keypads, and it provides better usability than the behavioral biometric schemes because its PIN registration process is much simpler. According to our experiments, our method guarantees EERs of 12.8%, 8.3%, and 9.3% for 4-digit PINs, 6-digit PINs, and 11-digit cell phone numbers, respectively, under the extremely conservative assumption that all users have the same PIN digits and cell phone numbers. Thus we can guarantee much higher performance in identification functionality by applying this result to a more practical situation where every user uses distinct PIN and sell phone number. Finally, our method is far more secure than the regular PIN entry method, which is verified by our experiments where attackers are required to recover a PIN after observing the PIN entry processes of the regular PIN and our method under the same level of security parameters.

In this paper, we propose a detailed component image classification algorithm by fashion item for unstructured data retrieval in the fashion field. Due to the COVID-19 environment, AI-based online shopping malls are increasing recently. However, there is a limit to accurate unstructured data search with existing keyword search and personalized style recommendations based on user surfing behavior. In this study, pre-processing using Mask R-CNN was conducted using images crawled from online shopping sites and then classified components for each fashion item through CNN. We obtain the accuaracy for collar of the shirt's as 93.28%, the pattern of the shirt as 98.10%, the 3 classese fit of the jeans as 91.73%, And, we further obtained one for the 4 classes fit of jeans as 81.59% and the color of the jeans as 93.91%. At the results for the decorated items, we also obtained the accuract of the washing of the jeans as 91.20% and the demage of jeans accuaracy as 92.96%.

Currently, by using the Internet, We can do varius things such as Web surfing, email, on-line shopping, stock trading on your home or office. However, as being out of the concept of security from the beginning, it is the big social issues that malicious user intrudes into the system through the network, on purpose to steal personal information or to paralyze system. In addition, network intrusion by ordinary people using network attack tools is bringing about big worries, so that the need for effective and powerful intrusion detection system becomes very important issue in our Internet environment. However, it is very difficult to prevent this attack perfectly. In this paper we proposed the algorithm for the detection of DoS attacks, and developed attack detection tools. Through learning in a normal state on Step 1, we calculate thresholds, the number of packets that are coming to each port, the median and the average utilization of each port on Step 2. And we propose values to determine how to attack detection on Step 3. By programing proposed attack detection algorithm and by testing the results, we can see that the difference between the median of packet mounts for unit interval and the average utilization of each port number is effective in detecting attacks. Also, without the need to look into the network data, we can easily be implemented by only using the number of packets to detect attacks.

This study was attempted in order to understand leisure phenomenon in Korea cultural area through relation of Leisure Activity, Leisure participation motivation, self -efficacy and Subjective well-being. The purpose of this study was to investigate the question that Leisure Phenomenon was studied focus on specific Leisure activity contents such as physical, tour science, though it is an important subject to explore as psychological and cultural. Also it suggested that what was the problem of established studies and what was the directions for future study. Concrete study problem was assumed three issues. (1)General state of leisure activity and leisure motivation in Korea, (2)The correlated relation between each motivation and self-efficacy and (3)The correlated relation between each motivation and Subjective well-being?. Through this, we conducted three results. Frist, the leisure motivation scale was factor analyzed and consequently 2 factors which can be considered as leisure motivation were prescribed. Also through the responded data, leisure activity of university students showed much more passive activity(e.g.,reading, listening music, movie, watching TV, Internet surfing etc.) than positive and physically activity. Second, each motivation was not significant in self-efficacy. Finally, among the motivation, especially emotion and psychological rest motivation was significant in the subjective wellbeing. These findings imply that general understanding about leisure phenomenon can different as the cultural thinking of leisure activity and leisure motivation.

The purpose of this study is to explore the feasible policy directions for sports welfare that can not only improve the standard of living through health but also ensure a happy and enjoyable life for the people of Gangwon Province. For this purpose, I have conducted studies such as the analysis on the sports class voucher project being implemented by the South Korean government and the case analysis in sports welfare, and present policy directions as follows. First of all, it is about upgrading the sports class voucher project. And as its implementation plans, I suggest ① increased publicity, ② the earmarking of the province's own budget for the sports class voucher project, ③ the establishment of a system for cooperation for work implementation between the related organizations and their staff in charge with a view to activating the sports class voucher project, and ④ the upgraded services for the sports class voucher project and the upgraded access to the life cycle-based universal welfare. Second, it is about using public sports facilities and developing various programs. I suggest the active utilization of the public sports facilities that enable people to learn the skills for such sports disciplines as baseball, badminton, ice sports, and golf and the development and distribution of distinctive educational programs for dance for media entertainment shows for female youths, climbing, cheer leading, fencing, surfing and horseback riding. Third, it is about nurturing the human resources and networking. For this, I suggest the creation of 'Sports Welfare Specialist Training Program' and the training of the college students majoring in sports science with the aim of creating a number of jobs. Fourth, it is about refurbishing the system and establishing the support system. I suggest the dismantling of the partitions in the welfare policy related to sports activities and the formation of (tentatively named) 'Gangwon Province Sports Welfare Implementation Committee', and the creation of (tentatively named) 'Sports Welfare Project Support Team' in Health, Welfare & Women's Affairs Bureau or Culture, Tourism and Sports Bureau in the short term and then its long-term expansion into (tentatively named) 'Gangwon Province Sports Welfare Support Center' in responding to the needs that reflect the provincial demographics, with a view to establishing a single lineup for the administrative support system. Furthermore, as budget and manpower are needed to realize customized sports welfare that suits the characteristics of the province and in which all the provincial residents can collect benefits, I suggest that the province provide the legal basis through creating 'Ordinance Promoting Sports Welfare in Gangwon Province' and pushing forward with (tentatively named) 'Gangwon Province Sports Welfare Competition' as what revises the sports class voucher project for the purpose of broadening the basis for sports welfare promotion.
