Purpose This article describes the historic and clinical aspects of the determination of the vertical dimension of occlusion and the synoptic procedure of the determination of the vertical dimension of occlusion in complete denture. The determining procedure of the susceptible vertical dimension of occlusion is one of the most important steps in construction of complete denture and prosthodontic treatment. It is considered essential for the improvement and the recovery of facial esthetics and stomatognathic functions. Results Several methods have been suggested for measurement of the vertical dimension of occlusion in the construction of complete denture and the prosthodontic rehabilitation. These range from pre-extraction records to the use of physiologic rest position, swallowing, phonetics, esthetics and facial proportion, etc. But, there is no universally accepted or completely accurate method. There seems to be no significant advantages of one technique other than those of cost, time and equipment requirements, and seems to be in controversial in determining the vertical dimension. Conclusion The vertical dimension of occlusion should be determined and reinspected carefully by dentist for a successful prosthesis with several methods. The more investigations are necessary for more objective and scientific techniques in determining the vertical dimension of occlusion.

Since the 20th century, there has been a growing interest in the new concept of fractals, a combination of mathematics and art, and the attempt to study the creative spatial aspects of the concept is being made. The purpose of this research is to examine artistic characteristics of fractal dimension and then analyze the types of fractal dimensions expressed in the fashion. Previous literature on fractals and dimension, and visual data on art and fashion collected over the Internet were used for analysis. Fractal dimension refers to the spatial concept of structural dimension of geometrical self-similarity. An analysis of the types of fractals seen in fashion revealed spatial expansion, the repetition in continual figures, superposition accordant to different sizes, and shades of different shapes. The aesthetic characteristics of fractal dimension appearing in fashions were examined based on analyses of fractal dimension types; the inherent characteristics of self-similarity, superimposition, and atypicality were found. Results obtained from this study are expected to be used as basic materials for the application of the design of fractal dimension into various perspectives of fashion.

In this paper, a self-organization framework for swarm systems in three dimensions is presented. The framework uses artificial potential functions(APFs) to direct the robots toward the goal as well as to keep them in a swarm system. This research extends conventional APFs used for self-organizations in two dimension environment to three dimensions. In three dimension environment, the ground potential for the boundary surfaces that commonly appear in three dimension environments is proposed. Accordingly, the comparison between the paths without and with the ground potentials shows the necessity and effect of ground potentials. Extensive simulations are given to show the effectiveness of the extended potentials and various properties in three dimension environments.

We examine the moduli space of oriented locally homogeneous manifolds of Type ${\mathcal{A}}$ which have non-degenerate symmetric Ricci tensor both in the setting of manifolds with torsion and also in the torsion free setting where the dimension is at least 3. These exhibit phenomena that is very different than in the case of surfaces. In dimension 3, we determine all the possible symmetry groups in the torsion free setting.

In these several years, as many people have been attracted by the functional cosmetics, there are a lot of study to enhance the stability of active ingredients for light, heat, oxygen, etc. in the academic and industrial field. Especially, catechin is well known as strong anti-oxidant, anti-inflammatory and reducing agent for oxidative stress but it is very unstable for light, heat, oxygen. etc. In this study, the stability and skin penetration of catechin are improved by 3-dimensional method. As I-dimension, porous silica is prepared using sol-gel method, and then catechin is adsorbed in pores of silica. As 2-dimension, solid lipid nanoparticles (SLN) are obtained using non-phospholipid vesicles. Finally 3-dimension is completion through lamellar phase self-organization that combines SLN catechin with skin lipid matrix. We used laser light scattering system, cyro-SEM, chromameter, HPLC and image analyzer to analyze our 3-dimentional systems. According to chromameter date, the color stability of 3-dimensional catechin is enhanced by 5-10 times compared with general liposome systems. We also confirmed through HPLC analysis that 3-dimensional catechin is more long lasting. The effect of skin penetration and wrinkle reduction are improved, too.

The purpose of this study were 1) to find out impression dimensions of the dress wearer with various motifs 2) to evaluate the impression effects of motifs in Korean traditional dress for women. The research method was a quasi-experimental with the between subjects design. The experimental materials developed for the study were a set of stimuli and response scale. The stimuli were consisted of 12 drawings with full factorial design of 3 independent variables : motif sorts (2:flower animal) motif types(2: realistic stylized) motif arrangements(3: all over the traditional to modern) The stimuli consisted of color photographs and color of clothing and motifs was controlled the blue. The response scales were consisted of 30 bi-polar adjectives. The subjects were 333 undergraduate college students of Taejon. The data was analyzed by factor analysis MANOVA and Duncan's multiple range test. Results were as follows: 1. The wearer's impression were consisted of the 3 different dimensions : attractiveness · dignity dimension. Interaction effect among motif sorts motif types and motif arrangements was significant on the same dimension. Interaction effect between motif sorts and motif arrangements was significant on the visibility dimension. 3. The motif arrangements were a significant variable on the attractiveness·dignity and the evaluation dimension. The traditional arrangement and the modern arrangement showed more faborable impression and the all over arrangement showed less favorable impression on the attractiveness·dignity dimension. The all over arrangement showed positive impression on the evaluation dimension and the traditional arrangement and the modern arrangement showed negative impression on the same dimension. There were no significant difference between flower sort and animal sort and also no significant difference between realistic type and stylized type in their impression effects.

The purpose of this study was to investigate the performance of clinical competency in nursing graduates and clinical nurses. The total of 234 subjects returned the questionnaire with 95% of response rates. The subjects of the study constituted of 195 nursing graduates and 39 clinical nurses. Self report questionnaires were used to measure the clinical competence of nursing graduates and clinical nurses. This instrument had four dimensions of competency : client and health need, nursing process, professional role, and nursing interventions. The data were analyzed by utilizing SPSSWIN and the results were as follows. 1) The mean score of the nursing intervention dimension was the most with 3.82 compared to professional role dimension(3.06), nursing process(3.03), client and health need dimension(2.94) in nursing graduates. 2) The mean score of the nursing intervention dimension was the most with 3.04 compared to client and health need dimension(2.82), professional role dimension(2.81), nursing process(2.77) in clinical nurses. And all of these dimensions' scores were lower than the nursing graduates' scores. 3) The mean scores of nursing process (t=3.76, p<.001) and professional role dimensions(t=3.53, p<.001) in nursing graduates were significantly higher than clinical nurses' scores. Our suggestions based on the results of this study is : 1. It is recommended to repeat the same designed study in large sample of clinical nurses for further study.
