The purpose of this study was to evaluate the adaptation of self-cured glass ionomer cement and resin-modified glass ionomer cement and polyacid-modified resin composite, which are light-cured giass ionomer cements, to dentin surface. Twelve extracted human maxillary and mandibular molar teeth were used in this study. The entire occlusal dentin surfaces of teeth were exposed with Diamond Wheel Saw and smoothed with sand papers (300, 600, 1200grits). They were randomly assigned into 3 groups according to glass ionomer cements used; Control group- Fuji II, Expeimental group 1 - Fuji II LC, Expeimental group 2 - Dyract. According to the manufacturer's directions, three glass ionomer cements were bonded to exposed dentin surfaces of the tooth crown and cured. Crowns and glass ionomers were trimmed after 24hrs and sectioned horizontally and vertically with diamond saw. The interface of glass ionomer cements and dentin was examined under SEM. The results were as follows : 1. Good adatation between glass ionomer cement and dentin on the horizontal section was showed in control and experimental group 1, but the gap of $20{\mu}m$, which was observed distinct separation between glass ionomer cement and dentin, was showed in experimental group 2. 2. Good adatation between glass ionomer cements and dentin on the vertical section was showed in control and experimental group 1, but the gap of 80-$100{\mu}m$ was showed in experimental group 2. 3. Cohesive fracture within glass ionomer cements in control and experimental group 1 was showed, but no cohesive fracture was showed in experimental group 2.

Changes in free amino acid concentrations is blood and various tissues were evaluated in cats adapted to the low-protein diet(20% protein, LPD) or the high-protein diet(60% protein, HPD) for 5 weeks. Cumulative body weigth gain for the 5 week period was 463$\pm$43g, and -128$\pm$40g for cats fed HPD and LPD, respectively. Feeding HPD significantly increased the size of liver and kidney. Cats adapted to HPD for 5 weeks have significantly elevated plasma concrntrations of essential amino acids (branched-chain amino acides, threonine, trytophan, phenylalanine and methoionine), whereas plasma levels of non-essential amino acids(alanine, asparagine, glycine, glutamine and serine) were significantly reduced in animals adapted to HPD(p<0.01, or p<0.001) compared to the values for the cats fed LPD. Changes in free amino acid concentratioks in whole blood induced by the variations in dietary level of protein closely reflect the pattern seen in plasma. Amino acids such as branched-chain amino acids, proline and threonine were most difficult to maintain homeostasis and consistantly elevated in lever, kidney, skeletal muscle and brain, as well as in blood of cats adapted to HPD(p<0.01 or p<0.001). All of the free amino acids in jejunum, excluding taurine and ornithine, were significantly elevated in animals adapted to HPD, most probably due to the rapid absorption of large amount of amino acids across the epithelium of small intestine.

본 연구는 D시와 G시에 소재한 어린이집 13기관에 재원 중인 영아 238명과 해당 영아의 어머니와 아버지 각 238명, 담임교사 45명(총 45학급)을 대상으로 영아의 기질과 어린이집 적응 변인이 교사의 직무만족과 교사-영아 관계에 어떠한 직 간접적인 영향력을 갖는지를 알아보고자 구조방정식 모형을 통해 분석하였다. 본 연구결과, 영아의 기질이 교사의 직무만족에 의해 매개되어 교사-영아관계에 영향을 미치는 것으로 나타났으며 영아의 어린이집 적응 또한 직무만족에 의해 매개되어 교사-영아관계에 영향을 미치는 것을 알 수 있었다. 따라서 교사의 직무만족은 교사-영아관계에 영향을 미치는 영아의 기질과 어린이집 적응, 두 잠재 변인 간의 매개 변인이다. 특히 영아의 기질은 교사의 직무만족과 교사-영아관계에 미치는 영향력이 영아의 어린이집 적응보다 크게 나타났으며, 영아-교사관계에는 기질이나 적응이 미치는 직접효과가 직무만족을 매개로한 간접효과보다 크게 작용하고 있었다. 이러한 결과는 영아와 교사관계에 있어서 영아의 기질변인이 중요함을 드러내준다. 그러므로 본 연구는 다양한 변인간의 관계를 규명함으로서 영아 연구 범위의 폭을 확장하였다는 의의가 있다.

The purpose of this study is to explore factors inducing dental hygiene student's activeness during clinical practice. A conceptual study was conducted for dental hygiene students who participated in the clinical practice for the first semester of 2019. The focus question was, 'What factors induced activeness during clinical practice?', a total of 33 statements were drawn by analyzing the responses. Results of multidimensional scale analysis and cluster analysis, there are six factors that induce activeness 'provide information on clinical practice', 'possibility to participate in clinical practice', 'possibility of adaptation', 'attitude of educator', 'patience of educator', and 'attitude toward trainees'. Among them, the most factor inducing activeness was the 'possibility to participate in practice'. The four items inducing activeness were 'provide a training manual', 'can be observed closely,' 'practice for a sufficient period', and 'the educator's attitude is kind'. The results of this study could be used as basic data to enhance the clinical practice effect of dental hygiene students.

In this paper, we propose a semi-supervised domain adaptation solution to deal with practical face recognition (FR) scenarios where a single face image for each target identity (to be recognized) is only available in the training phase. Main goal of the proposed method is to reduce the discrepancy between the target and the source domain face images, which ultimately improves FR performances. The proposed method is based on the Domain Adatation network (DAN) using an MMD loss function to reduce the discrepancy between domains. In order to train more effectively, we develop a novel loss function learning strategy in which MMD loss and cross-entropy loss functions are adopted by using different weights according to the progress of each epoch during the learning. The proposed weight adoptation focuses on the training of the source domain in the initial learning phase to learn facial feature information such as eyes, nose, and mouth. After the initial learning is completed, the resulting feature information is used to training a deep network using the target domain images. To evaluate the effectiveness of the proposed method, FR performances were evaluated with pretrained model trained only with CASIA-webface (source images) and fine-tuned model trained only with FERET's gallery (target images) under the same FR scenarios. The experimental results showed that the proposed semi-supervised domain adaptation can be improved by 24.78% compared to the pre-trained model and 28.42% compared to the fine-tuned model. In addition, the proposed method outperformed other state-of-the-arts domain adaptation approaches by 9.41%.

This study is to explore the essence and meaning of part-time job experience, in particular, to deduce growth experience through part-time jobs. This study is based on time-experience of phenomenological research method developed by the van Manen. For this research, the research data was collected by reviewing high school student part timer in Gyeonggi-do, those who had experience of average of two-year part time work or currently at work, and by undertaking in-depth interviews with seven of them from the March to April of 2017 with the agreements of the participants of this study. Time-experiences, i.e. part-time job experiences of youths, can be arranged as the following subjects. 'the feeling necessity part-time job and seeking it', 'adapting hard life of part-time', growth-experiencing through part-time work..The necessities for part-time job are feeling up consumption needs, aidsing domestic economy, pursuing independence, social and leisure life, self growth and preparing for the future. Adapting of part-time jobs are mastering, enduring, skillfuling work related to work adatation, and enduring ostracizing of old members, stopping and lasting, building bonds related to relationship adaptation. Growth-experiencing through part-time work are formig rational management for money, mental growth, preparing for the future. Based on these findings, the suggestion and limitation of the study were presented.
