The landscape of the education market is changing. As part of efforts to deal with the decrease of a school-age population in Korea, Korean universities and colleges are endeavoring to attract foreign students. Chinese students, the largest share of foreign university students in Korea, are becoming an important element at Korean universities and colleges. Chinese students face various kinds of difficulties while trying to cope with new environments in the country. This study aims to analyze the impact of academic factors and psychological factors of Chinese students on the level of adaptation to university life and their satisfaction with it. Data on 128 Chinese students attending D University located in Busan were collected and a path analysis was conducted using partial least squares (PLS) regression. Research results are as follows. First, professors as an academic factor and the level of interest of university staff have significant impact on the level of adaptation to university life while Korean language proficiency does not have significant impact on the level of adaptation to university life. Second, homesickness as a psychological factor is correlated to the level of adaptation to university life with significance while acculturative stress is not correlated to it. Third, the level of adaptation to university life is correlated to the level of satisfaction with university life. Based on these findings, the significance, limitations and future directions of this study are discussed.

It has been proven through many previous researches that the pretrained language model with a large corpus helps improve performance in various natural language processing tasks. However, there is a limit to building a large-capacity corpus for training in a language environment where resources are scarce. Using the Cross-lingual Post-Training (XPT) method, we analyze the method's efficiency in Korean, which is a low resource language. XPT selectively reuses the English pretrained language model parameters, which is a high resource and uses an adaptation layer to learn the relationship between the two languages. This confirmed that only a small amount of the target language dataset in the relationship extraction shows better performance than the target pretrained language model. In addition, we analyze the characteristics of each model on the Korean language model and the Korean multilingual model disclosed by domestic and foreign researchers and companies.

Objectives : It was to translate three neck and spinal pain disability questionnaires - the Neck Disability Index (NDI), the Neck Pain and Disability Scale (NPDS), and the Functional Rating Index (FRI) - into Korean language, and evaluate the psychometric properties of Korean versions of questionnaires to achieve a good cross-cultural adaptation. Methods : Forty (23 males, 17 females) subjects aged from 15 to 64 years old, participated to examine test-retest reliability. One hundred and eighty (76 males, 104 females) subjects with a primary diagnosis of non-specific neck pain and 81 healthy volunteers were undertaken to examine internal consistemcy, discriminative validity and longitudinal construct validity. Versions of each questionnaire in idiomatic modern Korean were developed using a procedure proposed by Beaton et al. (2000). To assess reliability, the Intraclass Correlation Coefficient (ICC $_{(2,1)}$) was calculated. Internal consistency was evaluated by Cronbach's alpha. Discriminative validity was examined with independent-group t-tests. Responsiveness was tested by calculating the effect size and standardized response mean for each questionnaire and using Pearson' s r and the area under the receiver operating characteristic curve analysis. Results : Test-retest reliability ofthe translated versions of the three disability questionnaires was excellent (ICC $_{(2,1)$ = 0.86-0.90). High internal consistency was found in the three disability questionnaires (Cronbach's alpha ranged from ${\alpha}=0.88$ for the FRI to ${\alpha}=0.96$ for the NPDS and 0.82 for the Short Form McGill Pain Questionnaire(SFMPQ)). the VAS subscale of the SFMPQ was found to be the most responsive of the subscales (ES=1.44, SRM=1.37). The VAS was also the most responsive pain and disability index in internal responsiveness analysis, although disability indices showed marginally better responsiveness when compared with external standards. No floor or ceiling effects were observed. Conclusions : It is concluded that the questionnaires were successfully translated and exhibit acceptable measurement properties, and may suggest that they are suitable for use in clinical and research application.

Web contents created for desktop screens give rise to problems when they are to be displayed on the small screens of mobile terminals. While in some cases some of the objects of a page may not be displayable due to the lack of browser capability, the entire page may not be displayable due to the incompatibility with the browser in other cases. In this paper, we introduce a new mobile content adaptation approach based on web clipping, which transforms an original page into one that is optimally displayed on a mobile terminal. In this method, a source page is automatically clipped and transformed according to the clip specification made by the content provider using a clip editing tool. The clip editing tool allows the user to specify group clips, multi-level cups and dynamic clips as well as simple clips, and the presentation layout through a graphic user interface. Based on the clip specifications, each clip is transformed into an intermediate meta-language document, which in turn is transformed into a presentation page in the target markup language. Transcoding of image objects in major image file formats is also supported.

A large number of current language processing systems use a part-of-speech tagger for preprocessing. Most language processing systems required a tagger with the highest possible accuracy. Specially, the use of domain-specific advantages has become a hot issue in machine translation community to improve the translation quality. This paper addresses a method for customizing an HMM or LHMM based English tagger from general domain to specific domain. The proposed method is to semi-automatically customize the output and transition probabilities of HMM or LHMM using domain-specific raw corpus. Through the experiments customizing to Patent domain, our LHMM tagger adapted by the proposed method shows the word tagging accuracy of 98.87% and the sentence tagging accuracy of 78.5%. Also, compared with the general tagger, our tagger improved the word tagging accuracy of 2.24% (ERR: 66.4%) and the sentence tagging accuracy of 41.0% (ERR: 65.6%).

This study examined the effect of bilingual bicultural home environment and mother's command of Korean language on their participation in child rearing as well as on children's developmental outcomes. We carried out Analysis of Covariance Structure using the 1st year(2011) data of Gyeonggi Education Welfare Panel, which consists of 459 matched pairs of immigrant women and their 5th~6th grade children living in Gyeonggi-do. The results indicated that when the immigrant mother has good command of Korean language and the children are exposed to their maternal culture and language, mothers tend to actively participate in child rearing and this in turn has positive effects on developmental outcomes of their children. These results demonstrate that Korean language programs targeting immigrant women by marriage are important not only for assisting their employment and adaptation but also for enhancing parenting behaviors in multicultural families. Moreover these findings suggest that we need to understand the bilingual bicultural home environment in these families as a significant resource that contribute to their children's developmental outcomes and not as a risk factor to their adaptation, as it has frequently been viewed.

In general multi-view system, all the view sequences acquired at the server are transmitted to the client. However, this kind of system requires high processing power of the server as well as the client, thus it is posing a difficulty in practical applications. To overcome this problem, a relatively simple method is to transmit only two view-sequences requested by the client in order to deliver a stereoscopic video. In this system, effective communication between the server and the client is one of important aspects. Therefore, we propose an efficient multi-view system that transmits two view-sequences according to user's request. The view selection process is integrated into MPEG-21 DIA (Digital Item Adaptation) so that our system is compatible to MPEG-21 multimedia framework. Furthermore, multi-view descriptors related to multi-view camera and systems are newly introduced. The syntax of the descriptions and their elements is represented in XML (extensible Markup Language) schema. Intermediate view reconstruction (IVR) is used to reduce such discomfort with excessive disparity. Furthermore, IVR is useful for smooth transition between two stereoscopic view sequences. Finally, through the implementation of testbed, we can show the valuables and possibilities of our system.

The purpose of this study is to consider the home environment and awareness of elementary school students in the first grade of elementary school, and to find ways to support them. Participants were 31 1st graders in elementary schools nationwide. Data collection was conducted from June 6, 2017 to July 7, 2017. The focus group interview was used as a data collection method for this study. Results were analyzed as 'The Changing family environment that first graders think' and 'First graders' awareness of elementary school'. 'The Changing family environment that first graders think' include 'Changes in language used by parents', 'Changes in how parents and families live', and 'What to do after school'. 'First graders' awareness of elementary school' was analyzed as 'Awareness of Elementary school life', 'Awareness of peers', 'Awareness of homeroom teacher', and 'Awareness of learning'. As the conclusion of this study, we suggest that because the children have more free time than attending kindergarten, they need quality programs and support plans to support their first grade primary adjustment. Also, we propose a common problem facing first-year students: the difficulty of adjusting to study and support for how to study in an easier way.

South Korea is changing into a multi-cultural society, due to an increase in international marriage, foreign workers and transcultural immigration. In addition, the number of North Korean defectors entering South Korea has increased and now, there are approximately 25000. Therefore, this review have focused on a research that pertains to adaptation and mental health concerns of their children. Children who have immigrated themselves or whose parents have immigrated, might experience language barriers, difficulties in school adjustment, identity confusion and mental health problems. However, their academic performance and developmental status are known to be variable and be affected by socioeconomic status and their parents' educational level. Studies that evaluated the psychological problems of North Korean adolescent refugees' indicated the need for interests in both emotional and behavioral problems. The risk factors of North Korean adolescent refugees' mental health are suggested to be past traumatic experiences, long duration of defection and short period of adaptation. When mental health professionals provide assessment and treatment, they should consider the pre- and post-migration experiences & cultural background that affect the illness behaviors and attitudes toward mental illnesses. Lastly, the majority of children with multi-cultural background are still under an adolescent period and we should follow up with long-term perspectives.
