In this paper, we compared the performance of "Network Intrusion Detection System based on attack feature selection using fuzzy control language"[1] and "Intelligent Intrusion Detection System Model for attack classification using RNN"[2]. In this paper, we compare the intrusion detection performance of two techniques using KDD CUP 99 dataset. The KDD 99 dataset contains data sets for training and test data sets that can detect existing intrusions through training. There are also data that can test whether training data and the types of intrusions that are not present in the test data can be detected. We compared two papers showing good intrusion detection performance in training and test data. In the comparative paper, there is a lack of performance to detect intrusions that exist but have no existing intrusion detection capability. Among the attack types, DoS, Probe, and R2L have high detection rate using fuzzy and U2L has a high detection rate using RNN.

Recently, the necessity and interest to improve the tourism preparedness for enhancing the quality of foreign tourists is increasing, but the related research is insufficient. The purpose of this study is to identify the preferential improvement elements related to the tourism preparedness of foreign tourists. To do this, we applied the R-IPA analysis to analyze and compare the elements affecting the tourist preparedness according to tourist type and time period. As a result of R-IPA analysis for all tourists, the elements that need to maintain the current quality levels were food, security, transit, shopping, and tourist attractiveness and the elements that need to be improved but low priority were language communication, travel expenses, and tourist information service. As a result of R-IPA analysis by tourist type, for individual tourists it is necessary to maintain current quality levels of transit, food, shopping, tourist attractiveness, and security. For group tourists, it is necessary to maintain current quality levels of accommodation, shopping, tourist attractiveness, and tourist information service, but food needs to be urgent improvement.

The objective of this study was to explore the humorous scenes shown in animation such as types of humor, frequency of humor, hours of humor, and correlation between subject of humor and supporting role. As the subjects of research, this study selected and that recorded the ten-times different number of audiences even though both works were produced by the same studio called 'Odolttogi'. In the results of analyzing those two works, there were differences. Drawing the characteristics of humor, the frequency of humor should be a lot more shown in the early to mid part than the latter part, and there should be diverse types of humor. And the frequency of humor by main characters should be increased. When the types of supporting roles were more diverse, the tendency of humor was also shown diversely. Also, the humor that was formed within relationships of characters was more effective than the humor formed alone. Through the slapstick or linguistic comedy in which such interactions are shown into actions, more diverse verbal plays could be shown. These elements could make it possible for animated works to diversely express more creative and funnier scenes of humor.

Background: Multicultural families are constantly on the rise as marriage migrants and foreign workers increase. Multicultural families appear to record poor health levels compared to native families. As health is a social issue, children of surviving generations of multicultural families are also a growing interest. This study was conducted to confirm the effect of multicultural families and parents' educational level on the scaling experience of children. Methods: For this study, the 2016~2018 Korea Youth Risk Behavior Web-based Survey data were used. In order to make the two groups of adolescents belonging to multicultural and native families similar, a total of 5,362 people were included in the survey, consisting of 2,681 individuals each from multicultural and native families using the propensity score matching method. Logistic analysis was performed to identify factors influencing the scaling experience of adolescent children. Results: The results confirm that, even after controlling for factors such as parents' educational level, household income, and children's oral health behavior, parents' nationality appeared to have a statistically significant effect on their children's scaling experience. In addition, it was confirmed that the experience of oral health education had a significant effect. Conclusion: Cultural heterogeneity and the lack of adequate language ability of immigrants affects health behavior and medical accessibility. Therefore, children from multicultural families are more likely to be exposed to unhealthy environments compared to the children of native Korean families. Based on an understanding of the socioeconomic multicultural background of individuals, education and public policy should be prepared to improve the awareness for the need for preventive oral health and provide unhindered accessibility to dental services.

The purpose of this study was to deepen our understanding about mothers' parenting stress in multi-cultural families. The study was conducted through in-depth interviews of 6 mothers from Mongolia, Philippines, and Japan who were living in Seoul. The findings of this study were as follows. First, mothers of multi-cultural families had difficulties of giving birth and child rearing, especially in the earliest years of their children. They were not fully adapted to the ways of living in Korea with little social support from family members and neighbors. Second, they were worried about their children's development, particularly language development due to their lack of understanding and fluency in Korean. Third, they were concerned about the cultural and racial discrimination against their children. They expected their children to be treated and respected equally like ordinary Korean children. Fourth, they were anxious about the fact that their children might not acquire the basic academic skills before they enter the elementary schools. Furthermore, they were worried that their children might not get as much educational support as they want. Fifth, despite the burden of mother's role in Korea, they wished to get a job to support their children for better education. In conclusion, the marriage immigrant mothers experienced the stress due to the lack of social support, the discrimination against immigrants, the possibilities of their children's delays in development, the disparity in the level of support for educating their children and the high expectations about their children's education in Korean society. Therefore it is necessary for the policy makers to consider more practical support system for the multi-cultural families in order for the marriage immigrant mothers to build up self-confidence in child rearing and educating their children.

The purpose of this study is to examine the perception of the right to vote of persons with developmental disabilities in college students. College students attending in A University and B University in Gwangju Metropolitan City were selected using convenience sampling and 370 samples were finally analyzed. The results were as follows. First, the subjects who took a disability course had high perception of the right to vote of persons with developmental disabilities. Second, it was discovered that the more times people participated in the volunteer work related to disabilities, the more recognition they had on the voting rights of people with developmental disabilities. Third, the subjects who responded for the need for the political rights of persons with developmental disabilities had more positive perception of the right to vote of persons with developmental disabilities than those who did not responded. Based on the findings, it was suggested that methods should be investigated to establish positive attitude and perception of the right to vote of persons with developmental disabilities in persons without developmental disabilities including college students.

This paper aims to find out the current state of early English education in the world(including Korea) and to suggest its more desirable direction, with special reference to TEFL in elementary schools of Korea. In fact English teaching in elementary schools of Korea has been put into practice as an extracurricular activity since 1982. But in 1995 the Ministry of Education proclaimed a policy to establish a TEFL program as the regular course in elementary schools of Korea since 1997. In this connection, the writer surveyed several kinds of theories about early English education to verify the necessity and validity of Korea's elementary school English education. The logical result from these theories is that younger children are better equipped to learn foreign languages with efficiency than older children or adults. However, as most studies are based on logical inferences rather than on direct observation or experimental evidence, we are not sure that those theories are right. In this view, the writer put stress on the preparation of educational environments to establish a more desirable direction of early English education in Korea, since Korea's elementary school English education will be practiced under EFL environment, not ESL environment. The writer also pointed out some problems of educational finances, the curriculum development process and its content, teaching materials(textbooks and tapes), English teachers, teaching methods, evaluation, educational facilities. This paper concludes that we have to try to solve these problems to succeed in a TEFL program in elementary schools of Korea and suggests several things for a more desirable direction of Korea's elementary school English education.

This study compared and analysed computer textbooks of the middle school from South Korea and North Korea for preparing the unification of the Korean Peninsula. According to the result of this study, the contents of South Korea textbook were equally selected from all scopes. By contrast, the contents of North Korea mostly consisted of the basic knowledge of computer, word-processing excluding the newest contents as Internet or Multimedia. But with the BASIC programming and algorithm for enhancement of the creative solving ability, prospective IT brains had been trained in North Korea. Moreover, due to differences of language policy and country that delivered IT technology, significant differences were found between South and North Korea in IT terminology. For preparing IT education after unification of the Korean Peninsula, both efforts of people who work in the fields of IT and school system in South and North Korea should be taken in order to relieve these differences.

Social Media transformed the mass media based information traffic, and it has become a key resource for finding value in enterprises and public institutions. Particularly, in regards to disaster management, the necessity for public participation policy development through the use of social media is emphasized. National Disaster Management Research Institute developed the Social Big Board, which is a system that monitors social Big Data in real time for purposes of implementing social media disaster management. Social Big Board collects a daily average of 36 million tweets in Korean in real time and automatically filters disaster safety related tweets. The filtered tweets are then automatically categorized into 71 disaster safety types. This real time tweet monitoring system provides various information and insights based on the tweets, such as disaster issues, tweet frequency by region, original tweets, etc. The purpose of using this system is to take advantage of the potential benefits of social media in relations to disaster management. It is a first step towards disaster management that communicates with the people that allows us to hear the voice of the people concerning disaster issues and also understand their emotions at the same time. In this paper, Korean language text mining based Social Big Board will be briefly introduced, and disaster issue detection model, which is key algorithms, will be described. Disaster issues are divided into two categories: potential issues, which refers to abnormal signs prior to disaster events, and occurrence issues, which is a notification of disaster events. The detection models of these two categories are defined and the performance of the models are compared and evaluated.

China's cultural diplomacy is mostly understood as an endeavour to build and project soft power, which draws on three sources of 'culture, political values and foreign policy' according to Nye. This paper focuses on the debates about the vehicle and agents of China's cultural diplomacy. It starts with a theoretical discussion of the competing views in the Chinese context, and develops an argument that the vehicle of China's cultural diplomacy tries to project soft power on two wheels of culture and political values, to serve the purpose of reshaping China's image away from being the 'cultural other' and 'ideological other' respectively. However, the state-led approach to driving this vehicle is generating some side effects with its sponsorship, censorship and presence in the driver's seat. Then the paper analyses the inherent tensions existing in practice both between the two sources of building soft power and between the two means of doing so, attraction and persuasion, with empirical evidence through a comparative case study of the Confucius Institutes in the US and South Korea. The finding shows that China's attempt at reshaping its image as an Eastern cultural contestant is often disrupted by its authoritarian political values, and the state-led persuasion is often reducing China's cultural attraction. Following this, the paper finishes with some recommendations regarding evolving the cultural diplomacy approach from a vertical one that is government-centred to a horizontal one that is network-based with multiple agents, and localising its practice by engaging the target audiences as stakeholders.
