The rural areas in South Korea have changed rapidly in the process of national land development. Rural landscapes have become discoloured, and their attractiveness has decreased as cities have expanded. But the attractiveness or multifunctional values of rural areas has become more important in contemporary society around the world. According to this social demand, the efforts of conserving the rural landscape are of high priority and the recovery of ruralism in the area is required. This study has tried to understand how the public image of ruralism in South Korea has been influenced by the news media. The study retrieved news articles using the web searching portal site from the six keywords, commonl13y used to refer to ruralism, including ‘rural landscape’, ‘rural community’, ‘rural tourism’, ‘rural life’, ‘rural amenity’, and ‘rural environment’. News data from the six keywords were also collected respectively from within the year-period of 2004-05, 2007-08, 2012-13, and 2016-17. In the text mining analysis, the nouns with high Degree Centrality were figured out, and the changes by year-period were identified. Then, LDA topic analysis was performed for text datasets of six keywords. As a result, the study found that the news articles gave an informed focus on only a handful of issues such as ‘poor rural living condition’, ‘regional or village improvement projects’, ‘rural tourism promotion projects’, and ‘other government support projects’. On the other hand, nouns related to virtues and values in the rural landscape were less shown in news articles. These results have become more apparent in recent years. In the topic analysis, 35 topics were identified. ‘village development projects’, ‘rural tourism’, and ‘urban-rural exchange projects’ were appeared repeatedly in several keywords. Among the topics, there are also topics closely related to ruralism such as ‘rural landscape conservation’, ‘eco-friendly rural areas’, ‘local amenity resources’, ‘public interest values of agriculture’, and ‘rural life and communities’. The study presented an image map showing ruralism in South Korea using a network map between all topics and keywords. At the end of the study, implications for Korean rural area policy and research directions were discussed.

Objectives : This study investigated the influence of traumatic experience on the ego identity, self-esteem, and general psychopathology of adolescent North Korean refugees. Methods : The participants were 146 adolescents North Korean refugees who attended H High School for North Korean refugees. We divided the subjects into two groups according to the severity of their traumatic experience : the more-traumatic-experience group and the less-traumatic-experience group. Each group performed self-report assessments including an assessment to reveal demographic characteristics, the Traumatic Experiences Scale for North Korean Defectors, the Scale for Ego identity, the Scale for Self-esteem and the Symptom Check-90-Revision (SCL-90-R). Statistical analysis of t-test and multiple regression utilized SPSS 12.0 for Window for comparison between more-traumatic-experience group and less-traumatic-experience group. Results : The prevalence of posttraumatic stress disorder among adolescents North Korean refugees was 37%. The factor with the greatest influence on ego identity was length of time living in South Korea, while, for self-esteem the most influential factor was perception of health. The more-traumatic-experience group had lower self-esteem scores on some subscales of the Scale for Ego identity. They had higher scores on all SCL-90-R subscales than the less-traumatic-experience group. Conclusion : Adolescent North Korean refugees experienced high rates of posttraumatic stress disorder. The more traumatic-experience-group had lower self esteem and poorer ego identity and mental health than the less-traumatic-experience group.

As a versatile processing method for nanoscale memory integration, laser-induced epitaxial growth is proposed for the fabrication of vertical Si channel (VSC) transistor. The fabricated VSC transistor with 80 nm gate length and 130 nm pillar diameter exhibited field effect mobility of 300 cm2/Vs, which guarantees “device quality”. In addition, we have shown that this VSC transistor provides memory operations with a memory window of 700 mV, and moreover, the memory window further increases by employing charge trap dielectrics in our VSC transistor. Our proposed processing method and device structure would provide a promising route for the further scaling of state-of-the-art memory technology.
