PURPOSE. The purpose of the study was to assess the influence of build orientations and density of support structures on the trueness of the 3D printed removable partial denture (RPD) frameworks. MATERIALS AND METHODS. A maxillary Kennedy class III and mandibular class I casts were 3D scanned and used to design and produce two 3D virtual models of RPD frameworks. Using digital light processing (DLP) 3D printing, 47 RPD frameworks were fabricated at 3 different build orientations (100, 135 and 150-degree angles) and 2 support structure densities. All frameworks were scanned and 3D compared to the original virtual RPD models by metrology software to check 3D deviations quantitatively and qualitatively. The accuracy data were statistically analyzed using one-way ANOVA for build orientation comparison and independent sample t-test for structure density comparison at (α = .05). Points study analysis targeting RPD components and representative color maps were also studied. RESULTS. The build orientation of 135-degree angle of the maxillary frameworks showed the lowest deviation at the clasp arms of tooth 26 of the 135-degree angle group. The mandibular frameworks with 150-degree angle build orientation showed the least deviation at the rest on tooth 44 and the arm of the I-bar clasp of tooth 45. No significant difference was seen between different support structure densities. CONCLUSION. Build orientation had an influence on the accuracy of the frameworks, especially at a 135-degree angle of maxillary design and 150-degree of mandibular design. The difference in the support's density structure revealed no considerable effect on the accuracy.

In this study, we investigated the effects of cooperative learning by the levels of students' performance goal orientation in science classes on 6th graders' science achievement and science learning motivation. Two classes (47 students) from an elementary school were respectively assigned to a control group and a treatment group. A performance goal orientation test and a science learning motivation test were administered as pretests. The intervention of cooperative learning lasted for 24 class periods. A researcher-made achievement test and the science learning motivation test were administered after the instructions. ANCOVA results indicated that the score of the treatment group was significantly higher than that of the control group in the achievement test. However, no interaction was found between the cooperative learning treatment and the levels of students' performance goal orientation. There were significant aptitude-treatment interactions in science learning motivation.

The aims of this study are to establish a mode of housing life style that meet the demands of families living in big cities, and the contribute to the development of a better housing life style pattern by considering metropolitan residents' choice of housing and basic concepts of their behavioral patterns. The results of this study were as follows: 1. Value orientation of family life was divided into value orientation of family and value orientation of housing. Value orientation of family was constituted of four factors such as 'harmony', 'leisure and hobbies', 'individual development and its support' , 'education' . Value orientation of housing is constituted of three factors such as 'physical characteristics of house' , '\`environmental condition', 'socio-economic conditions of housing'. The comprehensive life values were constituted of six factors such as 'the importance of communal family', 'the importance of housing decoration and housing life benefits', 'the importance of security and holding environment' , 'the importance of familial harmony', 'the importance of privacy', 'the importance of convenience and natural environment'. Based on three factors, were found to be fine types of value orientation of family life which were 'pursue healthy of family', 'comfort of family', 'clean environment', 'convenient environment', and 'harmonious relationship among family members'. Variables influencing the value orientation of family life were property and price of housing. 2. Consumption propensity when buying house, furniture and durables were constituted of four factors which were propensity to 'beauty', 'fashion', 'tradition and symbol', and 'pragmatic use'. Based on these factors, there were found to be four types of consumption propensity when buying house, furniture and durables which were 'fashion', 'tradition and symbol', 'beauty', and 'pragmatic use'. Variables influencing spending habits were found to be objective social class (SES), types of residence, wife's educational background, and price of housing. 3. Propensity to using space were constituted of three factors which were 'convenience', 'politeness and social grace', and 'housekeeping'. Based on these factors, there were found to be three types of propensity to using space which were 'individuality', 'convenience', and 'politeness and housekeeping'. Variables influencing propensity to use of space were found to be objective social class (SES), wife's educational background, types of homeownership and price of housing 4. According to this study, there were found to be six patterns of housing life style: 1) family that seeks formalist life, 2) family that seeks harmonious life, 3) family that seeks active healthy life, 4) family that combine various factors, 5) family that seeks convenience, 6) family that stresses environment.

Two cold-water coral taxa, Octocorallia in the class Anthozoa and Stylasteridae in the class Hydrozoa, were identified. Deep-water samples were collected in fishing nets at depths ranging between 20 and 200 m along the coasts of the East Sea in Korea from 1976 to 1993. The two species found in this study represent new records for Korea: Paragorgia arborea (Linnaeus, 1758) in the class Anthozoa, and Stylaster profundiporus Broch, 1936 in the class Hydrozoa. Two families, Paragorgiidae and Stylasteridae, are also newly recorded in Korea. Furthermore, the species name of another cold-water gorgonian species, Primnoa pacifica (Kinoshita, 1907) in the family Primnoidae, is amended in this report. The two newly recorded cold-water coral species from Korea are described in detail based on their morphological characteristics. Paragorgia arborea is characterized by its growth form, medulla and cortex, zooid dimorphism, canal system, and spicule composition. Stylaster profundiporus is distinguished by its external skeletal characteristics, such as the coordination of dactylopores and gastropores, presence or absence of gastrostyles and dactylostyles, cyclosystem orientation, ampullar position, gastropore tube shape, and coenosteal texture.

본 연구의 목적은 초등교사가 과학 수업과 관련하여 어떠한 지향을 추구하는지, 실제로 마주한 현실은 무엇이며, 그 속에서 어떻게 좌절과 실패를 극복해 나가는지 이해하기 위한 것이다. 이를 위해 두 초임교사인 박 교사와 최 교사의 과학 수업 실천 경험을 내러티브 탐구를 통해 살펴보고자 하였다. 박교사는 학습자 중심의 탐구 수업을 실천하길 원했지만, 현실에서는 교사 주도로 수업을 하게 되는 자신의 모습을 마주하였다. 최 교사는 구성주의에 바탕을 둔 과학 수업을 실천하길 원했지만, 현실에서는 스캐폴더가 아닌 지식 전달자로서의 자신의 모습을 마주하였다. 그러나 그들은 과학 수업에 대한 자신의 지향을 포기하거나 좌절에 머물기보다는 각자가 생각하는 방식으로 자신의 지향에 다가가려고 노력하였다. 본 연구는 자신의 과학 수업 지향이 잘 구현되지 않을 때 초임교사가 어떠한 전략을 만들어 가는지 이해함으로써 예비교사에서 교사로의 성공적인 전환을 이끌 단서를 제공할 수 있을 것이다.

Companies want universities to produce graduates with creativity and problem-solving skills, and for this reason universities have extended engineering design education, including in the field of architectural engineering. This paper investigates an engineering design class in the Department of Architectural Engineering, J University. The class was taught in 2010 and 2011using an Action Learning (AL) teaching-learning strategy. The students responded that the level of participation and satisfaction was high in the Action Learning classes, and role allocation or responsibility and communication of the project teams were very effective. But it was also found that as Action Learning is such a new method for students of engineering design, an orientation session that describes what to do and what to prepare should be given before the class starts.

This paper aims to investigate factors affecting museum visits of young people in Vietnam by sending questionnaires to 2106 young people aged between 14-30 in Vietnam. With the support of SPSS version 2016 and STATA version 22, this paper illustrates that the empirical findings are appropriate with previous literature reviews. Research hypotheses such as learning purposes, intrinsic motivation, extrinsic motivation, and museum architecture are significantly and positively correlated with museum visits measured through customer visiting intention, customer satisfaction, and customer loyalty. Furthermore, males have a stronger interest in visiting the museum but a low re-visit intention than females. People with a higher level of education and higher income are also more likely to visit the museum than those with a lower level of education and income. Finally, the research results suggest that the family class and the orientation of parents play an important role in encouraging children to increase museum visiting intention; however, children of high-class families are less likely to have a high intention, satisfaction, and loyalty toward museum visitation than children of lower-class families.
