This paper proposes an effective recognition method of VPI patient's speech employing DNN-HMM-based speech recognition system, and evaluates the recognition performance compared to GMM-HMM-based system. The proposed method employs speaker adaptation technique to improve VPI speech recognition. This paper proposes to use simulated VPI speech for generating a prior model for speaker adaptation and selective learning of weight matrices of DNN, in order to effectively utilize the small size of VPI speech for model adaptation. We also apply Linear Input Network (LIN) based model adaptation technique for the DNN model. The proposed speaker adaptation method brings 2.35% improvement in average accuracy compared to GMM-HMM based ASR system. The experimental results demonstrate that the proposed DNN-HMM-based speech recognition system is effective for VPI speech with small-sized speech data, compared to conventional GMM-HMM system.

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.

The purpose of this study was to examine the relationship between major satisfaction and university life adaptation according to the amount of physical activity for university students. This study implement survey to the 201 university students. Descriptive statistics, reliability analysis, one-way ANOVA and pearson's correlation analysis were conducted for data analyses. The results are as follows. First, university students' major satisfaction with the amount of physical activity is statistically significantly higher than that of low-intensity physical activity groups (p<.05). Second, university life adaptation according to the amount of physical activity was found to be statistically significantly higher in high-intensity physical activity groups than in medium-intensity physical activity groups and low-intensity physical activity groups (p<.05). Lastly, according to the relationship between physical activity, major satisfaction, and university life adaptation of university students, male students have a static correlation between physical activity, major satisfaction (general satisfaction), and university life adaptation (personal emotion adaptation) and female students have a static correlation between physical activity and university life adaptation(social adaptation) (p<.05). This study confirmed that the amount of physical activity of university students is related to their major satisfaction and adaptation to university life. Based on this conclusion, it is expected that university students will be able to manage their university life through physical activities.

Sri Lanka is an island nation susceptible to climate-related disasters and extreme weather events. Kurunegala City is the developing capital city of the North-Western Province of Sri Lanka. Changes in rainfall patterns and a steadily increasing annual average temperature amounting to 0.69±0.37℃ were observed in the city area. Generally, urban areas are at risk due to the lack of climate change adaptation provisions incorporated in the development plans. This study was conducted to investigate the characteristics of Krunegala City, Sri Lanka and develop an appropriate climate change adaptation plan for the city. Site investigation and qualitative risk assessment were conducted to devise a plan relevant to the climate change adaptation needs of the city. Qualitative risk analyses revealed that drinking water, water resources, and health and infrastructure risks were among the major concerns in Kurunegala City. Low impact development (LID) technologies were found to be applicable to induce non-point source pollutant reduction, relieve urban heat island phenomenon, and promote sound water circulation systems. These technologies can be effective means of alleviating water shortage and reducing urban temperature. The measures and strategies presented in this study can serve as reference for developing climate change adaptation plans in areas experiencing similar adverse effects of climate change.

The purpose of this study is to analyze the factor giving effect to department selection, learning adaptation and attributional-style after entering school by selecting university students as targets and help high school students who will graduate soon and university students select department and direction. Those were analyzed by using 287 questionnaire data from June 1 to June 30, 2011. The study result revealed that 64.5% of students considered 'popularity and employment prospect' first when they select department. Generally, it was researched that when selecting department, 68.8% of women and 78.7% of health major considered 'popularity and employment prospect'(P<0.05, P<0.01). For learning adaptation and attribution trend of each major, health major showed that learning adaptation was high when motif was high and application score was high and for the relationship with attributional-style, health major showed higher internal attributional-style, showing significant difference(P<0.05). When synthesizing the results above, it is necessary to develop and use the program that can develop internal attribution trend of students on the basis of attributional-style. For planned and careful selection, it is necessary to perform synthetic consulting through direction search program that considers entrance period of middle school or high school, general affairs of university or direction guide to increase department or direction adaptation in the future.

Objectives: This study evaluates the bond strength and marginal adaptation of mineral trioxide aggregate (MTA) Repair HP and Biodentine used as apical plugs; MTA was used as reference material for comparison. Materials and Methods: A total of 30 single-rooted teeth with standardized, artificially created open apices were randomly divided into 3 groups (n = 10 per group), according to the material used to form 6-mm-thick apical plugs: group 1 (MTA Repair HP); group 2 (Biodentine); and group 3 (white MTA). Subsequently, the specimens were transversely sectioned to obtain 2 (cervical and apical) 2.5-mm-thick slices per root. Epoxy resin replicas were observed under a scanning electron microscope to measure the gap size at the material/dentin interface (the largest and smaller gaps were recorded for each replica). The bond strength of the investigated materials to dentin was determined using the push-out test. The variable bond strengths and gap sizes were evaluated independently at the apical and cervical root dentin slices. Data were analyzed using descriptive and analytic statistics. Results: The comparison between the groups regarding the variables' bond strengths and gap sizes showed no statistical difference (p > 0.05) except for a single difference in the smallest gap at the cervical root dentin slice, which was higher in group 3 than in group 1 (p < 0.05). Conclusions: The bond strength and marginal adaptation to root canal walls of MTA HP and Biodentine cement were comparable to white MTA.

Investigating cross-cultural differences of family stress and adaptation in Korea and Australia, 49 families in open adoption were administered the Family Index of Regenerativity and Adaptation-General (McCubbin, 1987), Family Problem Solving Communications (McCubbin et al., 1988), and Social Support Index (McCubbin et al., 1982). Data were analyzed by T-test and correlation analysis. Results indicated that adoption itself was the primary stressor in both countries. Korean adoptive families were under stress by family-oriented factors; Australian adoptive families experienced external family stress. Regarding family hardiness, coping efforts and family communication, Australian adoptive families reported significantly higher family functioning than Korean adoptive families. Findings suggested that a broad range of social support is needed to improve family adaptability in both countries.

Purpose: This study was aimed to identify pregnancy and childbirth experience of Vietnamese marriage migrant women who have pregnancy and childbirth experience during adaptation to Korea. Methods: A qualitative study was conducted, using focus group interview. Data were collected from October 2011 to March 2012 from 10 Vietnamese women of 2 focus groups who have experienced pregnancy or childbirth in Korea. Data were analyzed using content analysis in order to identify significant themes. Results: This study was analyzed into five major themes: 'difficulty of adaptation to other cultures', 'difficulty and joy of pregnancy', 'effort to live as a Korean', 'not-so-difficult childbirth', and 'unbearable postpartum conditions.' Conclusion: It is meaningful of this study to reveal this: for Vietnamese marriage migrant women, the support for adaptation to Korean culture and postpartum care is a priority rather than the necessity of development of the program about pregnancy and childbirth.
