The purpose of this study is to develop and verify the effectiveness of a group art therapy program to help children from multicultural families adapt to school life by using Kinetic School Drawing(KSD). The result of this study showed that the group art therapy program of the multicultural family's children may have a positive effect in aiding their school life adaptation. The results showed considerable and statistical outcome in the fore and after drawing inspection of the dynamic KSD. Also, the size of the self-image became bigger and their expressions has been increased. The qualitative analysis also showed a huge change in dynamistic personal relationships due to the relationship with their peers with the same aged and the tutor. This study emphasizes the importance of the group art therapy program to be applied before children are admitted to school because of growing recognition of concern about the maladjustment of rapidly growing multicultural family's children. It is also suggests that the group art therapy program of growing multicultural family's children should be viewed with an ecological point of view.

Recently, the use of media has become a daily life due to Covid-19, and education using media has expanded for teenagers. The purpose of this study is to empirically verify how media usage characteristics affect social relationships and school adaptation through the self-efficiency and immersion of teenagers at the youth education site. This study was collected and distributed questionnaires to 250 high school students in Seoul from November 14 to November 21, 2020. The results of the study were derived with a total of 249 questionnaires, excluding one missing questionnaire, and the hypothesis was verified using a Covariance Structure Analysis. Research has shown that, first, the existing, individual, and utility among the characteristics of using youth media have a significant effect on self-efficiency, respectively. Second, only entertainment among the characteristics of youth media use was found to have a significant effect on immersion. Third, immersion has a significant definition effect on school adaptation, and self-efficiency has been shown to have a definition impact on social relationships. Based on this study, we believe that it will be used as a fundamental resource for the development of youth media usage and policy direction in the age of the ever-changing Covid-19.

We propose a novel speaker adaptation method using acoustic model clustering. The similarity of different speakers is defined by the cosine distance between their i-vectors (intermediate vectors), and various efficient clustering algorithms are applied to obtain a number of speaker subsets with different characteristics. The speaker-independent model is then retrained with the training data of the individual speaker subsets grouped by the clustering results, and an unknown speech is recognized by the retrained model of the closest cluster. The proposed method is applied to a large-scale speech recognition system implemented by a hybrid hidden Markov model and deep neural network framework. An experiment was conducted to evaluate the word error rates using Resource Management database. When the proposed speaker adaptation method using i-vector based clustering was applied, the performance, as compared to that of the conventional speaker-independent speech recognition model, was improved relatively by as much as 12.2% for the conventional fully neural network, and by as much as 10.5% for the bidirectional long short-term memory.

In this paper, we propose an efficient algorithm for adaptation of tracking windwo, which improves tracking performance of a correlation-based video tracker by rejecting background effect originated from a time-varying target. Th eproposed adaptation algorithm ajdusts the size of a tracking window by using the ratio of spatial gradient power in target region to that in backgorund region, which is especially adequate for a correlation-based tracker. Experimental results for synthetic and real image sequences show that the proposed method adapts a tracking window well to a time-varying target and so greatly suppresses background effect, which makes improvement of trakcing performance.

Objectives: This study evaluated the effect of ultrasonic agitation of mineral trioxide aggregate (MTA), calcium silicate-based cement (CSC), and Sealer 26 (S26) on adaptation at the cement/dentin interface and push-out bond strength. Materials and Methods: Sixty maxillary canines were divided into 6 groups (n = 10): MTA, S26, and CSC, with or without ultrasonic activation (US). After obturation, the apical portions of the teeth were sectioned, and retrograde cavities were prepared and filled with cement by hand condensation. In the US groups, the cement was activated for 60 seconds: 30 seconds in the mesio-distal direction and 30 seconds in the buccal-lingual direction, using a mini Irrisonic insert coupled with the ultrasound transducer. After the materials set, 1.5-mm thick sections were obtained from the apexes. The presence of gaps and the bond between cement and dentin were analyzed using low-vacuum scanning electron microscopy. Push-out bond strength was measured using a universal testing machine. Results: Ultrasonic agitation increased the interfacial adaptation of the cements. The S26 US group showed a higher adaptation value than MTA (p < 0.05). US improved the push-out bond strength for all the cements (p < 0.05). Conclusions: The US of retrograde filling cements enhanced the bond to the dentin wall of the root-end filling materials tested.

Objectives: The internal adaptation of composite restorations with or without resin modified glass ionomer cement (RMGIC) was analyzed non-destructively using Microcomputed tomography (micro-CT). Materials and Methods: Thirty intact human teeth were used. The specimens were divided into 3 groups. In the control group, the cavities were etched with 10% phosphoric acid for 15 sec. Composite resin was filled into the cavity without adhesive. In group 1, light cured glass ionomer cement (GIC, Fuji II LC, GC) was applied as a base. The cavities were then etched, bonded, light cured and filled with composites. In group 2, the cavities were then etched, bonded, light cured and filled with composites without base application. They were immersed in a 25% silver nitrate solution. Micro-CT was performed before and after mechanical loading. One-way ANOVA with Duncan analysis was used to compare the internal adaptation between the groups before or after loading. A paired t-test was used to compare internal adaptation before and after mechanical loading. All statistical inferences were made within the 95% confidence interval. Results: The silver nitrate solution successfully penetrated into the dentinal tubules from the pulp spaces, and infiltrated into the gap between restoration and pulpal floor. Group 2 showed a lower adaptation than the control group and group 1 (p < 0.05). There was no significant difference between the control group and group 1. For all groups, there was a significant difference between before and after mechanical loading (p < 0.05). Conclusions: The internal adaptation before and after loading was better when composites were bonded to tooth using adhesive than composites based with RMGIC.

Objectives: The purpose is to prepare measures to effectively improve college life adaptation by identifying relevance between interpersonal relation disposition and college life adaptation, college life stress and college life adaptation for dental hygiene students. Methods: 375 dental hygiene students attending some local universities in Gyeonggi-do were sampled for convenience. The results of this study are as follows. Results: First, As a result of interpersonal relation disposition according to general characteristics, superiority-dominance tendencies were higher in first and third graders, in groups with grades above 4.0 and groups with lower subjective economic levels. And the stress of college life was high for second graders and students with lower grades than 2.0. Second, According to the correlation between factors, governance-dominance, independence-responsibility, sympathy-acceptance, sociable-friendliness, and ostentation-intoxication of interpersonal tendency factors had proportional relationship with college life adaptation, rebellion-distrust and college life stress had inverse relationship. Third, The results of multiple regression analyses to identify factors that affect college students' adaptation to college life were in the order of stress in college life, first grade, sociable-friendliness, second grade, rebellion-distrust. Conclusion: In order to improve college life adaptation, counseling and practical mediation programs should be developed and applied to effectively manage and control the negativity and positivity implied by interpersonal relationships and college life stress.

본 연구는 지역사회SES에 따라 부모양육태도와 아동의 학교적응 및 공격성에 차이가 있는지, 또 지역사회SES는 부모양육태도를 통제한 후에도 학교적응 및 공격성에 영향을 미치는지 파악하고자 진행되었다. 지역사회SES는 대구시 30세 이상 인구대비 대학교 이상(수료 및 중퇴 포함) 재학 및 졸업자 비율을 기준으로 상, 중, 하 세 가지로 나누었고 연구대상은 이 세 지역의 초등학생 441명을 대상으로 하였다. 분석결과를 살펴보면 지역사회SES에 따라 민주적 양육태도와 허용적 양육태도에 차이가 나타났다. 또한 지역사회SES가 중간 이상인 지역의 학생들이 학교에 더 잘 적응하며, 공격성의 정도는 더 낮은 것으로 나타났다. 지역사회SES에 따른 학교적응과 공격성의 차이는 부모양육태도를 통제하고서도 여전히 나타남으로써 지역사회SES가 가족효과를 넘어 아동에게 독립적 영향을 미치고 있음을 확인하였다. 이와 같은 연구결과를 바탕으로 실천적 개입 방안을 제시하였다.

This study examined positive and negative marital factors on social adaptation to South Korea among North Korean refugees. In terms of previous studies, family variables play an important role in the adaptation to new society among refugees. We analyzed three major marital factors of marriage background, dyadic adjustment, and marital violence. Marital factors consisted of place of birth, place of marriage, dyadic consensus, dyadic satisfaction, dyadic cohesion, emotional violence, physical violence, and sexual violence. We analyzed the data of 295 North Korean refugees who resided in Seoul, Gyeonggi province and Incheon using snowballing sampling. The result indicated that the refugees married to non-Korean partners (including Korean-Chinese, Chinese, or Russian) are more likely to suffer in social adaptation. Place of marriage (whether the couple got married before escaping, during the escape or after living in South Korea) did not have a significant impact. Dyadic satisfaction was helpful in social adaptation, while sexual violence had a negative effect. The findings of this study suggest alternatives for more successful social adaptation by North Korean refugees to South Korea, a need for more services that target married couples and families rather than individuals, and suggestions for the use of counselors who are also North Korean refugees.
