The purpose of this study was to understand the influence of social network site (SNS) addiction on the ability of nursing students to adjust to university life and to generate the basic data to develop programs that could improve this ability. The data was collected from questionnaires that were filled out by 255 nursing students in two universities located in Jeollanam-do and Gyeonggi-do from May 16, 2020 to May 20, 2020. The data was analyzed using the SPSS 23.0 program (frequency, ANOVA, Pearson's correlation, multiple regression). The mean scores of SNS addiction and adjustment to university life were 2.16±0.54 (range:1-5) and 3.13±0.39 (range:1-5) respectively. SNS addiction accounts for 27% of the variance in adjustment to university life. The study concluded that SNS addiction negatively affects adjustment to university life among nursing students. To ensure better adjustment a program should be developed to treat SNS addiction early. Also, a study will have to be conducted to determine the time when tendency toward SNS addiction becomes apparent, to initiate treatment.

If the frequency of a particular class is excessively higher than the frequency of other classes in the classification problem, data imbalance problems occur, which make machine learning distorted. Corporate bankruptcy prediction often suffers from data imbalance problems since the ratio of insolvent companies is generally very low, whereas the ratio of solvent companies is very high. To mitigate these problems, it is required to apply a proper sampling technique. Until now, oversampling techniques which adjust the class distribution of a data set by sampling minor class with replacement have popularly been used. However, they are a risk of overfitting. Under this background, this study proposes ROSE(Random Over Sampling Examples) technique which is proposed by Menardi and Torelli in 2014 for the effective corporate bankruptcy prediction. The ROSE technique creates new learning samples by synthesizing the samples for learning, so it leads to better prediction accuracy of the classifiers while avoiding the risk of overfitting. Specifically, our study proposes to combine the ROSE method with SVM(support vector machine), which is known as the best binary classifier. We applied the proposed method to a real-world bankruptcy prediction case of a Korean major bank, and compared its performance with other sampling techniques. Experimental results showed that ROSE contributed to the improvement of the prediction accuracy of SVM in bankruptcy prediction compared to other techniques, with statistical significance. These results shed a light on the fact that ROSE can be a good alternative for resolving data imbalance problems of the prediction problems in social science area other than bankruptcy prediction.

This study was conducted to identify the conceptual definitions and attributes of fatigue in hemodialysis patients based on the Hybrid Model of concept development. The Hybrid Model was used to investigate the main attributes and indicators of the concept by applying three stages. After a literature review, data were collected through observation and interviews including qualitative research in the field work stage. The participants included 10 patients in hemodialysis center of two hospitals in Gwang-ju, Korea. The attributes of fatigue concept in the hemodialysis patients were divided into four dimensions, physical activity, affective mood, social role, and cognitive reflection. The definition of fatigue by hemodialysis patients was defined as 'subjective feeling usually experienced in four dimensions during the process to recognize and adjust energy deficiency and limited functions caused by uremia and repeated hemodialysis for chronic renal failure'. Considering the dimensions and attributes derived from this study, it may be possible to develop an effective intervention program for fatigue in hemodialysis patients.

As the damage caused by the abnormal climate due to climate change is increasing, the interest in resilience is increasing as a countermeasure to this. In this study, the resilience of Suwon city was examined and the plan to improve the resilience were derived against climate impacts such as drought, heatwave, and heavy rain. Urban resilience is divided into social resilience (e.g. vulnerable groups, access to health services, and training of human resources), economic resilience (e.g. housing stability, employment stability, income equality, and economic diversity), urban infrastructure resilience (e.g.residential vulnerability, capacity to accommodate victims, and sewage systems), and ecological resilience (e.g. protection resources, sustainability, and risk exposure). The study evaluated the urban resilience according to the selected indicators in local level. In this study, the planning elements to increase the resilience in the urban dimension were derived and suggested the applicability. To be a resilient city, the concept and value of resilience should be included in urban policy and planning. It is critical to monitor and evaluate the process made by the actions in order to continuously adjust the plans.

This study aims to understand the background and characteristics of receiving Hallyu based on the cognitions and attitudes toward Korea and Korean culture in the Philippines. With the background of Business Hallyu and Cultural Hallyu between the two countries, this study conducted the Focus Group Discussion(FGI) research, literature research and analyzed the statistical resources. The economic and cultural exchanges between Korea and the Philippines have been increased by the effect of Hallyu, but the socio-cultural conflicts, such as Kopino issue, crimes related to Koreans have been also grown. Thus, the Hallyu research focused on the Philippines is necessary, and it will be a cruical variable to forecast the socio-cultural relationship between Korea and the Philippines. The FGI research recruited participants in both undergraduates in the Phillippines and the Filippino migrants in Korea. The FGI participants of each group shows the differences of cognitions, attitudes, and actions to consume Hallyu, and the participants of both groups agrees that experiences of contacting Koreans influence on understanding Korea and its culture. The FGI participants have tried to watching Korean dramas, learning Korean languages, and building relationships with Koreans in order to adjust Korean culture. In order to improve the relations between Korea and the Philipines, Hallyu needs to promote its values as the unique culture and also universal culture in the world. Korea should increase understanding of the Filippino culture to overcome cultural differences and make efforts on localize the Hallyu 3.0 in the Phillippines.

Purpose: The purpose of this study is to identify the changes to nursing activities of nurses on patients with DNR (Do-Not-Resuscitate) order and factors associated to the changes. Methods: Data were collected using a structured questionnaire for 173 nurses at general hospitals. Logistic regression analysis was performed on the data using SAS 9.4. Results: With 39 nursing activities, an average of 60.4 (34.9%) nurses reported an increase in the activities, 102.4 (59.2%) no change and 10.1 (5.9%) a drop. The activity increase was the greatest in the social area, and the physical area was where the activities decreased the most. The activity increase was associated knowledge competency (9 items), attitudes (2 items), practical competency (4 items) and work load (14 items were). Conclusion: To offer systematical care for DNR patients, it is necessary to expand nurses' knowledge through end-of-life education and adjust their workload and provide a support system at the department level.

Problems concerning the vital registration system and its management, errors and methods to adjust them in the vital registration data in Korea have been studied. It is found that birth and death registration rates were above 95% in 1994. The registration rates rose rapidly since 1970 due to 1) simplification of registration form, 2) improving accessibility by allowing registration at the current residence, 3) enforcing fine against non-registration, and 4) improvements in social security system. However, there should be some continuing efforts for further improvement of the vital registration system. The content error in the data could be substantially reduced following the rapid rise of the registration rates in the 1980s, though this has never been actually studied. There are still substantial registrations with false date of death. The false date of events may affect the computed vital rates specially when the registration rates are rapidly rising. Especially the death rates of the young can be seriously affected. A study on the data in the 1970s shows that death of age between 3 to 19 has been over-registered up to 67% compared with the expected. It is a serious matter that some researchers analyze the registration data without adjusting the errors. It is strongly recommended for the Government Statistical Office to undertake a study on the registration behavior of the people.

This study performed quality study to examine cognition and experience as it is about husband role of wife's perception in rural multicultural family. Specifically the results of in-depth interviews with 13 females in rural multicultural family was analyzed through phenomenological method. The results were as followings: first, wife's cognition about husband role in rural multicultural family, they were 'nice and warm man', 'no special thought', 'clean and cool looking man', 'man without straitening wife', 'husband taking care of housekeeping', 'having independent family' and 'strong responsibility to children'. Females in rural multicultural family did not deeply think about husband's role at international marriage, but it could be known that vague longing for rich country, Korea by Korean wave and its expectation continued to expectation on husband. Second, they were 'good-tempered and nice to me', 'adjust to me', 'irresponsibility and apathy', 'cannot lean to him', 'no housekeeping', 'intermediate role between his family', 'more taking care of children, parents and relatives', 'drink, gambling and violence'. The experience of husband role was little different from cognition of husband role by females in rural mulitcultural family.

In the era of globalization, a significant number of young students go abroad to learn English. By reviewing the trends and characteristics of this phenomenon, this study will focus on the adjustment of young Korean students in Australia. During June and July 2002, two questionnaire surveys were conducted for year 7 to year 12 Korean students at the Saturday Schools in Sydney Australia and for the youth group at the Sydney Catholic Church. More data was collected from interviews with 31 Korean teachers at the Saturday Schools and Linfield Korean school, as well as observations of the students in the Sydney area. The study divided the students into four groups: 1) Korean immigrant students, whose parents immigrated to Australia; 2) Individual Korean students who went alone to Australia to study; 3) Students whom live in Australia with one parent (usually their mother), whilst the other parent (usually their father) who provides financial support by working in Korea; and 4) students who accompanied their parents whom were dispatched for temporary employment or study in Australia. Moreover the study focused on the following; their academic performance, school activities, motivation, social relations, and their overall satisfaction with their studies and their stay in Australia. The findings indicated that the temporary overseas Korean students, especially those that are not with their parents do not adjust as well as the Korean immigrant students. The students who were not accompanied by their parents to Australia had the most difficulties adjusting as they were more vulnerable and fell behind with their studies. Therefore, the results support the concerns of Korean teachers in Australia about parents sending young students alone abroad.

Since 2015, the government has been striving to strengthen the software capabilities required for future talent through software-oriented university in Korea. In the university selected as a software-oriented university, basic software education is given to all departments such as humanities, social science, engineering, natural science, arts and the sports within the university in order to foster convergent human resources with different knowledge and software literacy. In this paper, we analyze the contents of basic software education for twenty universities selected as software-oriented universities. As a result of analysis, most of the basic software education which is carried out to the students of the non-majors students was aimed at improvement of problem solving ability centered on computational thinking for future society and improvement of convergence ability based on computer science. It uses block-based educational programming language and text-based advanced programming language to adjust the difficulty of programming contents and contents reflecting characteristics of each major. Problem-based learning, project-based learning, and discussion method were used as the teaching and learning methods for problem solving. In the future, this paper will help to establish the systematic direction for basic software education of non-majors students.
