In this paper, a robust discrete-time adaptive control with compensation is proposed for single-input single-output discrete-time plants which have unmodeled dynamics. The stability of the overall system is studied using the conic sector stability theorems when a normalized constant gain parameter adaptation algorithm and a properly chosen compensation are used. An illustrative exmple shows that this compensation can also increase the parameter adaptation speed. And a method of compensation using the adaptive observation is also discussed.

In this paper, we propose the effective exchange-method of a user profile for adapted contents services in the contents adaptation system. The profiles continuously exchange among the devices of contents adaption system for providing the adapted contents to a user. The profile should be also exchanged according to periodic, aperiodic, event, request and response. Consequently, a lot of network traffic occur and computing power require. Solving theses problem, the profile exchange research needs. we analyze creation information, exchange information, and exchange form of the profile information in contents adaptation system for effective profile exchange and define exchange procedure of the profile using the analyzed profile information. we also propose providing method of the profile configured information for decreasing profile processing time and user setting method for decreasing the number of profile transmission. As a result of performance evaluation, providing method of the profile configured information reduce 7% processing time and user setting method decrease the number of profile transmission are effective to exchange the profile.

SVC (Scalable Video Coding) is a new video coding standard to provide convergence media service in heterogeneous environments with different networks and diverse terminals through spatial-temporal-quality combined flexible scalabilities. This paper presents the performance analysis on packet loss in the delivery of SVC over IP networks and an efficient adaptation method to packet loss caused by buffer overflow. In particular, SVC with MGS (Medium Grained Scalability) as well as spatial and temporal scalabilities is addressed in the consideration of packet-based adaptation since finer adaptation is possible with a sufficient numbers of quality layers in MGS. The effect on spatio-temporal quality due to the packet loss of SVC with MGS is evaluated. In order to minimize quality degradation resulted by packet loss, the proposed adaptation of MGS based SVC first sets adaptation unit of AU (Access Unit) or GOP corresponding to allowed delay and then selectively discards packets in order of importance in terms of layer dependency. In the experiment, the effects of packet loss on quantitative qualities are analyzed and the effectiveness of the proposed adaptation to packet loss is shown.

Purpose: The purpose of this study was to describe health problems and psychosocial adaptation in children with cancer and to determine the relationship between these two variables. Method: The data were collected from parents of 61 children with cancer, aged 4-11 years at one university hospital in Seoul. The instruments for this study were the Korea Child Behavior Check List (KCBCL) and a physical symptom checklist developed by the researchers. Result: The major health problems were coughing, sleeping disturbances, fatigue and weakness. The total behavior problem score for children in the cancer group was higher than the score for those in the norm group. The scores on the scales for withdrawal, somatic complaints, social immaturity, and internalizing problems were higher in the children with cancer compared to normative findings. Scores on social and school competence in the cancer group were lower than the norms for healthy children. The relationship between health problems and psychosocial adaptation was significant in the subscales of withdrawal, anxiety/depression, internalizing problems and social involvement in the off therapy group. Conclusions: This study shows the various areas that need further study in caring for children with cancer.

The purpose of study is to provide efficient initial approaches for counseling in social work practice settings. First, it attempts to identify the correlation between the Myers-Brigg's Type Indicator(MBTI), a personality index based on the theory of psychological typology, and Personality Adaptation Types(PAT) models. Second, it attempts to develop a counseling method which can be applied to the initial interview, using the paradigm of door to therapy such as "Open Door", "Target Door", and "Trap Door" based on the PAT theory. The result of the quantitative study showed the correlation between MBTI and PAT as follows: MBTI Extrovert and Feeling(E, F) type was statistically correlated to hysterical PAT. MBTI Extrovert, Intuition and Perceiving(E, N, P) type was statistically correlated to Obsessive-Compulsive PAT. In conclusion, this study finds that when a clinical social worker approaches a client with the client's MBTI personality type and an interventional personality adaptation theory approach such as "Open Door", "Target Door", or "Trap Door", the efficiency of communication is increased significantly.

Purpose: The purpose of this study was to identify the relationship among family stress, family meaning and family adaptation of families with high risk neonates. Method: The date was collected on the basis of self- report questionnaires (August 2004 to March 2005); Tow-hundred twelve parents, who had high risk neonates in C hospital's neonatal intensive care unit, participated on request. Results: Family sense of coherence, family meaning, social support, family stress, marital communication and patient condition had a significant, direct effect on family adaptation. Family cohesion, religion, confidence in the health professional, and length of stay had a significant, direct effect on family meaning. Conclusion: The results of this study suggest the consequences associated with high risk neonates may be alleviated by a family support intervention designed to improve parental communication skills as well as to maintain family cohesiveness. Medical care could also encourage more emotional support of parents towards their neonate.

This research is intended to explore the adaptation process for immigrant women and their Korean spouses through a qualitative method. It is aimed at understanding how immigrant women and their Korean spouses have adjusted to their lives in Korea over the last 10 years and how they have dealt with difficulties in the adaptation process. The participants were 15 intermarried couples consisting of a Southeast Asian wife and a Korean husband. They got married through matchmakers and have children between the ages of 8 and 13. The study carried out in-depth interviews. To analyze the interview data, the qualitative software program Nvivo8 was used. The results showed that immigrant women and their Korean spouses experienced confusion at first. They struggled adapting to each other's lifestyles and made efforts to establish harmony. In the end, they made their own family identity as a multicultural family. The study widens the understanding of multicultural families by focusing on both wives and husbands. Also, the use of the Nvivo8 software strengthens the reliability of the data analysis. The results will contribute to providing interracial couples with the adaptive strategies.

Purpose: This study was conducted to generate a grounded substantive theory of the adaptation process of nurses who return to work after taking parental leave. Methods: Individual in-depth interviews with 13 participants were conducted between June and September 2014. Participants were interviewed 1~3 times; interviews were continued until the data became saturated. Data were analyzed using Strauss and Corbin's grounded theory method. Results: The core category of experience of the process of adaptation as a nurse who returned to work after parental leave was 'trying to regain one's previous position'. Participants used five interactional strategies: 'preparing in advance', 'initiating relationships with colleagues', 'keeping a positive attitude', 'understanding parenting helpers', 'Taking burden off one's mind'. Conclusion: The results of this study provide a theoretical basis for the adaptation process of nurses returning to work after taking parental leave. The importance of improving nurses' attitudes to their co-workers who take parental leave is highlighted along with the necessity of providing a family-friendly work environment. These results can be used to develop supportive policies and programs for nurses who return to their work after parental leave.

Purpose: This study is a qualitative research to identify new nurses' adaptation experience to sleep changes. Method: Grounded theory methodology was utilized. Participants were 10 new nurses from one university hospital. The information was collected and analyzed using the grounded theory of Corbin and Strauss'(2008). Results: Through constant comparative analysis, central phenomenon was identified as 'Shaky daily life due to the sleep change'. A core category emerged as 'In the shaky daily life, go grab my position', Causal conditions were 'Heaviness in shift work', 'Not released after getting off work', and 'Body and mind are exhausted'. Context were 'An environment that does not tolerate mistakes' and 'Clogged breathing due to worries'. Intervening factors were 'Support of colleagues', 'Recovery volition in restoration of altered relationships due to sleep'. Action/Interaction Strategies were 'To strive for a good sleep', 'Require a reasonable duty schedule' and 'Find a breakthrough'. Consequences were 'Become the master of shaky daily life' and 'Accepting the life of a nurse'. Conclusion: New nurses experience sleep patterns changes from the hospital shift system. but throughout the process of adaptation, came to accept sleep disorder as part of the life of a nurse.
