The purpose of this study is to identify the posture correction program as the development of the posture maintenance performance, and search for the more efficient posture correction program. The data analysis was processed by SPSS. The data was analysed with $x^2$-test, t-test, pearson product moment correlation, and stepwise regression analysis. The finding of this study is as follows: There are the homogeneity between two groups was verified on the know ledges CF=.697, df=2, P>.05), self-efficacy(F=.098, df=2, P>.05) about the posture. The developed posture correction program has proved to enhance the posture maintenance performance(knowledge t=1.60, P<.05 ; posture manintenance t=7.69, P<.01). The type of posture correction program showed some significant differences (t=5.62, P<.01) in the accuracy of movement way among the factors of the posture maintenance performance. The posture maintenance performance affected self-efficacy. Therefore, the major conclusion is as follows: The posture correction program was meaningfully effective on developing the posture maintenance, and with practice created accuracy much more on the posture maintenance movement way. The development of the posture maintenance performance affected the increase of self-efficacy about the posture. The self-efficacy has proved so powerful factor to influence on the posture maintenance performance development. So, the posture correction program should be done systematically and continually, and developing the posture maintenance performance should be done with practice. After the education, it should be reinforced through practice, midterm identification and reeducation and motivated with recognizing the accurate posture measurement. And it should be created the correction program to develop the high self-efficacy about the posture. It needs the strategy to educate the correct posture individually, and to spread to the society for healthy life style.

Most functional programming languages allows programmers to write ambiguous rules, under the strategy that pattern-matching will be performed in a direction of 'from top to bottom' way. While providing programmers with convenience and intuitive understanding of defining default rules, such ambiguous rules may make the semantics of functional languages unclear. More specifically, it may fail to apply the equational reasoning, one of most significant advantage of functional programming, and may cause to obscure finding a formal way of translating functional languages into the ${\lambda}$-calculus; as a result, we only get an ad hoc translation. In this paper, we associate with separability of term rewriting systems, holding purely-declarative property, pattern-matching semantics of lazy functional languages. Separability can serve a formalism for translating lazy functional languages into the ${\lambda}$-calculus.

With the rapid development of computer hardware and invention of various game-related technologies, the quality of games has been greatly improved and the genres of games have been diversified. Yet, in comparison, puzzle games have held to the past simple way of games, which has only led to a depression of the puzzle game market. This paper is the first attempt to overcome limits of the current puzzle games, by finding a breakthrough in three-dimensional puzzle games. In order to describe a realistic puzzle assembly in a three-dimensional puzzle game, this paper aimed to design a structure assembly technique made up of three steps that used a proper process to handle structure suitable to assembly, an elaborate way of collisions between individual objects and a physical structure. Through this technique, we intend to show in a simple experiment that it is possible to minimize the calculation cost in the assembly process and at the same time to achieve an elaborate puzzle assembly between structures.

The temple Hoeamsa(檜巖寺) was repaired by Naong(懶翁), and with this the power of the temple became far greater to be the greatest Buddhist temple during late Goryeo and early Joseon. Naong's reconstruction of Hoeamsa was originated from Jigong(指空)'s teaching 'Samsan Yangsu(三山兩水).' But it is not clear whether Samsan Yangsu really meant Hoeamsa. By the way, after 14 years, Naong suddenly remembered this word and began to repair Hoeamsa in a large scale. From this, we can guess that Naong tried to give the contemporary Buddhism some change through the repair of Hoeamsa. But, as King Gongmin(恭愍王) the greatest supporter of Naong was suddenly assassinated, the political situation changed a lot and Naong also died unexpectedly. Naong's death brought out the critical sense to Hoeamsa and, in the process to resolve the crisis, the repair of Hoeamsa began to be justified through diverse religious factors. As these were expanded and developed on and one, Hoeamsa came to be honored as the most divine temple in Korea during the early Joseon dynasty. Furthermore, into the cause structure for the Naong's repair of Hoeamsa, the influence of Jajang was added through Odaesan Buddhism. As we can well understand, late Silla situation of Jajang and the late Goryeo of Naong were very similar and the both Buddhist leaders should have derived out some religious solution for them. In other words, both of them had a similar recognition in finding the religious solution for the contemporary crises. It becomes a way to understand the Hoeamsa repairing structure taken by Naong and his disciples. Therefore, by comparing the similar religious solution structures given by Jajang and Naong and by clearer understanding on Samsan Yangsu spirit, we can see the repair of Hoeamsa and the related aspects more accurately.

The objective of this study was to investigate the sibling relationship, the attachment to parent and peer according to children's gender, birth order, and sibling gender composition. For this purpose, 697 male and female elementary students answered the questionnaire, who were selected because they had only one sibling. The date were analysed by t-test and partial correlation. The major finding of this study showed that children who had same sex of sibling perceived more positive way to their younger sibling then children who had different sex of sibling and that children who had female sibling perceived more positive way to sibling relationship, attachment to parent and their peers than children who had male sibling.

The purpose of this study was to investigate the level of multicultural competencies and influencing factors of multicultural competencies in nursing students. The participants of 181 subjects were recruited from three colleges in K and B. A structured questionnaire was used to collect data, and data were analyzed using descriptive statistics, t-test, one way-ANOVA and multiple regression with SPSS/WIN 17.0. Results showed that cultural competence of nursing students was middle range. There was a significant positive correlation between cultural competence, empathy, and self-efficacy. The significant factors influencing cultural competence of nursing students were empathy, self-efficacy, and education of multiple cultural. These three factors explained 51% of the variance in multicultural competencies of nursing students. The study finding suggest that to develop the learning program with achievement level of multicultural competencies for nursing students.

PURPOSE. The aim of this Fourier transform infrared (FTIR) spectroscopic study was to measure the degree of conversion (DC) of dual-cured resin cements light-irradiated through zirconia ceramic disks with different thicknesses using various light-curing methods. MATERIALS AND METHODS. Zirconia ceramic disks (KT12) with three different thicknesses (1.0, 2.0, and 4.0 mm) were prepared. The light transmittance of the disks was measured using ultraviolet visible near-infrared spectroscopy. Four different light-curing protocols were used by combining two curing light modes (Elipar TriLight (standard mode) and bluephase G2 (high power mode)) with light-exposure times of 40 and 120 seconds. The DCs of the two dual-cured resin cements (Duo-Link and Panavia F2.0) light-irradiated through the disks was analyzed at three time intervals (3, 7, and 10 minutes) by FTIR spectroscopy. The data was analyzed using repeated measures ANOVA (${\alpha}$=.05).Two-way ANOVA and Tukey post hoc test were used to analyze the 10 minute DC results. RESULTS. The 1.0 mm thick disk exhibited low light transmittance (<25%), and the transmittance decreased considerably with increasing disk thickness. All groups exhibited significantly higher 10 minute DC values than the 3 or 7 minute values (P<.05), but some exceptions were observed in Duo-Link. Two-way ANOVA revealed that the influence of the zirconia disk thickness on the 10 minute DC was dependent on the light-curing methods (P<.001). This finding was still valid even at 4.0 mm thickness, where substantial light attenuation took place. CONCLUSION. The curing of the dual-cured resin cements was affected significantly by the light-curing technique, even though the additional chemical polymerization mechanism worked effectively.

Recently SW education has been emphasized in Korea, but many students do not have many opportunities to learn computer science. In this paper, I organized a computer science show to enhance interest and understanding of computer science. The computer science show consisted of understanding binary systems, send a text message, parity bit magic, finding a number card, and collecting colors (orange games). I applied the computer science show to elementary school students and looked at the results. Most of the students who participated in computer science shows did not have an "participation experience of computer science shows". As result of surveys, many students answered "I am interesting about computer science shows," "I am interested in computer science," and "I would recommend it to my friends nearby." Through research, I learned that computer science shows are a way for elementary students to draw interest in computer science and to create curiosity and interest in computer science. I found from research that computer science shows are a way to reduce students' learning burdens and to increase interest in computer science.

It is no exaggeration to say that the productivity of a research using computer simulations on complex molecular systems like biomolecules depends on the ability of the sampling algorithm to explore the relevant parts of configuration space. In this study, we investigate the properties on the mutiensemble sampling (MES) which is one of the solutions that surmount limitations of conventional sampling algorithms. Works for finding out practical systematic ways of using the MES efficiently to explore distantly separated regions in configuration space are performed. In this work, the more generalized form of weighting function for MES is used and 'cavity formation in water' is simulated using Monte Carlo. investigating the correlation of simulation parameters and the efficiency of the method, we propose a practical way of maximizing the power of the MES. We applied the way to 'cavity formation in water' and were able to explore the parts of configuration space relevant to cavities of radius from 0 to 5.6A in a single simulation.

The traditional way of access to image information is through descriptive keyword searching. However, many studies in image indexing and retrieval have reached a consensus on the difficulties and limitations of text-base image description. This research investigates the feasibility of using visual browsing that is being used comparatively much less than keyword searching. The effectiveness of Keyword access versus visual access were examined through experiments in which participants searched for pictures of specified emotions using different access modes: keywords only, visual browsing only, and the combination of both. It was found that keyword searching was appropriate for clean searches while visual browsing was the effective way to browse many pictures quickly, thus finding more relevant pictures. Findings and results can guide of images retrieval systems, especially the retrieval system of subjective and interpretive information.
