Nowadays Korean society has a fast growing population of North Korean immigrant youth. Especially, North Korean immigrant youth, who are discontinuing formal education, experience difficulties in social exclusion and adaptation. Therefore, the purpose of this study was to understand the experiences of adaptation and social support of North Korean immigrant youth discontinuing formal education, and to seek affirmative supporting plans and solutions for their adaptation. The methodology utilized for this study was a case study research. On the basis of the results and categorization, 'a network between overall categories and of early adaptation' was derived. The major findings of this study are summarized as follows. First, the participants of this study experienced major difficulties during 'economical adaptation', and their economical adaptation was strongly interrelated with their 'educational adaptation'. The discontinuing of their education resulting from their fleeing period caused 'academic differential and age disparity.' Thus they could not enroll in the formal education system, and their insufficient educational background resulted in low wages and overwork due to manual labor jobs. Second, participants recognized 'interpersonal relations' as the most essential factor in adaptation, and 'social support' from the interpersonal relations played an important role in adaptation to and comfort in Korean society. 'Interactions with South Koreans' was recognized as a significant resource for gaining informational and appraisal support, but was not activated satisfactorily. On the other hand, interaction with North Korean immigrants was avoided by the reason that 'there's nothing to learn', however emotional support from North Korean immigrants of close relationship played an important role in participants' adaptation, especially in all aspects of psychological adaptation. Third, participants experienced a lot of difficulties and stresses in their 'physical health and psychological adaptation'. Their chronic diseases worsened by remaining untreated, and female perceived symptoms were observed more often than in male. Meanwhile, excessive 'stresses' from the unfamiliar environment of South Korea negatively affected their psychological adaptation. However, they were satisfied with sense of liberty and security from living in a democratic society.

The retinomotor responses of jack mackerel, Trachurus japonicus and carp, Cyprinus carpio were studied for the different strobe flash frequencies in respects of the application of the light stimulus to herding and barrier system. The strobe flash frequencies ranged at 1.7, 5, 10, 25, 430Hz in jack mackerel and 1.7, 5, 25Hz in carp. The retinal adaptation ratio was examined histologically according to the time elasped of 1, 5, 10, 30min after turning on the light in each experimental condition. Cone index were determined in order to express the retinal adaptation ratio. Jack mackerel showed an increase of the retinal adaptation ratio ranging from average 27% at the pre-stimulus light to 42.6%, 49.8%, 59.8% and 83.1% at the irradiation times of 1, 5, 10 and 30min., respectively. Carp showed an increase of the retinal adaptation ratio ranging from average 28.4% at the pre-stimulus light to 51%, 53.9% and 91.3% at the irradiation times of 1, 5 and 30min., respectively. The light adaptation process was observed to be fast approximately in order of 430Hz, 25Hz, 5Hz, 1.7Hz and 10Hz for jack mackerel, and 25Hz, 5Hz and 1.7Hz for carp, and to be light-adaptated in 30 minutes.

The objective of this study is to figure out some specific features that were found during the adaptation process of migrant women by marriage to their local community, and also to elicit certain practical implications to facilitate their adaptation, based on the findings. For data collection, in-depth interviews were conducted with eight migrant women by marriage and the interviews were tape-recorded for transcription. For analysis, phenomenological method, particularly, Colaizzi method was adopted, by which meaningful statements in the data were categorized into themes and theme clusters. A total of 7 thematic unts, 17 themes and 47 meanings were elicited from the analysis and these 7 thematic units were "reinforcement of inner capability"; "cultural assimilation"; "to be a limited benefit receiver"; "no human network"; " impossible to be optimistic about future"; "hoping to reside in their local community"; "possible to leave Korea." Finally, this study suggested the implications for social welfare practices to facilitate the adaptation of immigrant women by marriage in their local community.

While many factors could be mentioned to the rapid development of Israel for the last 50 years, it could not be overemphasized the critical role of large scale influx of Jewish immigrants not only in the process of achieving national independence but to the development of modernization. It is well known that mass influx of people in a relatively short period of time may cause serious social problems in various areas such as housing shortage, increasing crime rate, etc. Nontheless, Israel is avidly recognized as a country that successfully overcome such problems by means of creating systematic social integration systems and practicing various adaptation assistance programs for new immigrants. This study was concerned with such a successful social adaptation-assistance programs of Israel for large scale immigrants those who came from all over the world with different socio-economic background. In order to answer the research questions, following two areas of topics were researcher`s main concern. First, organizational structure and functions of the Ministry of Immigrant Absorption of Israel and Jewish Agency that are primarily responsible for the economic, occupational, social, and cultural integration of immigrants during their first three years (five years for housing-aid) in Israel. Second practical adaptation assistance programs such as direct absorption basket, Ulpan, Aliyah 2000, special projects of Keren Hayesod and two of Aliyah Absorption Centers are examined. And lastly some of implications and suggestions are provided in the conclusion section in relation with social adaptation-assistance and integration of reunified Korea, especially from the point of North Koreans.

One of the most popular approaches to parameter adaptation in hidden Markov model (HMM) based systems is the maximum likelihood linear regression (MLLR) technique. In our previous study, we proposed factored MLLR (FMLLR) where each MLLR parameter is defined as a function of a control vector. We presented a method to train the FMLLR parameters based on a general framework of the expectation-maximization (EM) algorithm. Using the proposed algorithm, supplementary information which cannot be included in the models is effectively reflected in the adaptation process. In this paper, we apply the FMLLR algorithm to a pitch sequence as well as spectrum parameters. In a series of experiments on artificial generation of expressive speech, we evaluate the performance of the FMLLR technique and also compare with other approaches to parameter adaptation in HMM-based speech synthesis.

Unsupervised domain adaptation often gives impressive solutions to handle domain shift of data. Most of current approaches assume that unlabeled target data to train is abundant. This assumption is not always true in practices. To tackle this issue, we propose a general solution to solve the domain gap minimization problem without any target data. Our method consists of two regularization steps. The first step is a pixel regularization by arbitrary style transfer. Recently, some methods bring style transfer algorithms to domain adaptation and domain generalization process. They use style transfer algorithms to remove texture bias in source domain data. We also use style transfer algorithms for removing texture bias, but our method depends on neither domain adaptation nor domain generalization paradigm. The second regularization step is a feature regularization by feature alignment. Adding a feature alignment loss term to the model loss, the model learns domain invariant representation more efficiently. We evaluate our regularization methods from several experiments both on small dataset and large dataset. From the experiments, we show that our model can learn domain invariant representation as much as unsupervised domain adaptation methods.

The main purpose of this study is to provide the necessary information for educational intervention by discovering the components and factors related to the adaptation experience of male students in the department of nursing. The participants were seven male nursing students. Data were collected from in-depth interviews, and the results were analyzed by the Giorgi's phenomenological analysis method. The main components of adaptation experience of participants were summarized into four categories: 'hopes and expectations for the future careers,' 'conflicts and wandering under realistic issues,' 'compromise and emotion management,' and 'efforts for self-growth.' Causative, accelerative, and recursive characteristics were shown among these components. The adaptation process was structured in the temporal context. The results suggest that for amicable adaptation, internal controls, such as 'improving willpower,' 'inspiring solid career awareness,' and 'selecting adaptation strategy' were all critical. Moreover, the support of families, relatives, college seniors, and department professors were revealed as the factors that help in the adaptation experiences. Based on the results, further studies are required to identify the dropout rates by maladaptation of male nursing students, and analyze possible factors that contribute to dropout and maladaptation. In addition, it is necessary to construct various coping methods and practical support systems, as well as to develop appropriate educational programs.

Mobile content adaptation is a technology of effectively representing the contents originally built for the desktop PC on wireless mobile devices. Previous approaches for Web content adaptation are mostly device-dependent. Also, the content transformation to suit to a smaller device is done manually. Furthermore, the same contents are provided to different users regardless of their individual preferences. As a result, the user has difficulty in selecting relevant information from a heavy volume of contents since the context information related to the content is not provided. To resolve these problems, this paper proposes an enhanced method of Web content adaptation for mobile devices. In our system, the process of Web content adaptation consists of 4 stages including block filtering, block title extraction, block content summarization, and personalization through learning. Learning is initiated when the user selects the full content menu from the content summary page. As a result of learning, personalization is realized by showing the information for the relevant block at the top of the content list. A series of experiments are performed to evaluate the content adaptation for a number of Web sites including online newspapers. The results of evaluation are satisfactory, both in block filtering accuracy and in user satisfaction by personalization.

Purpose: This study was to explore work experience among nurses with low back pain. Specific aims were to identify problems nurses face as workers at a hospital and how they interact with other workers. Methods: Grounded theory methodology was utilized. Data were collected from iterative fieldwork with individual in-depth interviews from 9 nurses with low back pain as key informants, and a head nurse and a charge nurse who had experiences working with nurses with low back pain as general informants. Results: Through constant comparative analysis, a core category emerged as "to make one's own ground". The process of "to make one's own ground" was identified as four categories: perception of limitations, intervening conditions, balancing limitations, and controlling limitations. Intervening conditions were identified as 'working conditions' and 'personal traits'. Conclusion: Findings of the study indicate that there is a need for health professionals and administrators to understand limitations to working experience among nurses with low back pain. In addition, institutional and psychological support program is needed to improve an adaptation to working environment among nurses with low back pain.
