In this paper, the present state of the experiments in the mechanical engineering education is analyzed and the improving methods of the experimental education are presented. Data at twelve universities are collected. In spite of the general understanding of the importance of the experiments, the portion of the experiments is less than 10%. It shows the need to increase the experiments. Experiments for basic mechanics are fairly well performed, but experiments for applied subjects would be strengthened. Several improving methods such as systematic support for experiments, use of the exclusive assistants for experiments, and so on are discussed.

Make-up illustration is a field of creativity with visible creative and artistic values; its ultimate functions include communication of information, artistic expression, and recording. Establishing the make-up illustration education environment for the twenty-first century, there is an urgent need for research and development of professional curricula for basic art education and illustration education. It is extremely important for educators and institutions teaching make-up illustration to recognize that training of highly creative and professional beau designers through systematic educational structures is the ultimate foundation for enhancing competitiveness of the beauty industry despite the present reality that there are insufficient studies and publications on beauty illustration and that there is lack of illustration lecturers and artists equipped with professional beauty knowledge. Therefore, this study was conducted to research and analyze offering of illustration subjects by 160 beauty-related vocational schools and 16 4-year undergraduate colleges in the make-up field, which is the field with most creative art activities among the three representative beauty majors, namely make-up, hair, and skin. Education of make-up illustration must not remain as simple short-term education. The curricula must be specialized for providing solid foundation of basic majors. In terms of education content, strong emphases must be made for original and creative mark-up designs as well as purposes, functions, and necessity of make-up design and illustration. The curricula must include systematic, logical and artistic elements. Through the course of this study, which researched, analyzed and proposed measures for education content of make-up illustration, it was found that make-up illustration is the most appropriate subject that fulfills both the ultimate education objectives of beauty colleges and the demand by the society for beauty professionals. It is hoped that make-up illustration is emphasized and recognized for its importance and necessity as an education subject so that similar basic major subjects will further be researched and developed for specialized education.

Objectives: The purpose of this study was to provide a basic data of nutrition services in home health care by analyzing hospital-based home-visit nutrition education needs of patients at discharge. Methods: Data was collected from September 11 to October 12, 2012 by administering questionnaires to 289 chronic disease patients to be discharged from a university hospital in Pusan. The home-visit nutrition education instruments used for collecting data were developed by the researcher. Results: Regarding the demands of home-visit nutrition education, 62.3% of subjects were willing to use home-visit nutrition education and 37.7% weren't. The main reason for using the home-visit nutrition education was "the effective nutrient management in consultation with an individual's doctor", 38.9% and 31.2% of patients who did not wish to use the service gave the reason for their decision as, "Just by managing the nutritional requirements of a family's diet and, the patient will be able to fully recover", respectively. As for the demand, classified with the areas of home-visit nutrition education, the demand for the area of basic nutrition (3.75/5.00) was the highest followed by, the area of educational nutrition (3.74/5.00), therapeutic nutrition (3.67/5.00), and dietary nutrition (3.55/5.00). The demand for the area of educational nutrition was high "Considering the state of dietary management, such as disease status and drugs", 73.7%. As for the relation between the characteristics of the study subjects and analysis of demand home-visit nutrition education, the characteristic of subjects, that is, "regular home-visit nutrition education", "practice of diet therapy after discharge" had a significant difference statistically (p < 0.01). As for the relation between the needs for fundamental home-visit nutrition education and the demand of home-visit nutrition education, basic nutrition, educational nutrition, therapeutic nutrition, and dietary nutrition had a significant difference statistically (p < 0.01).

This study aimed to identify curriculum gaps and a pilot study to provide the programs for selection during clerkship. Over the course of a clerkship, students analyze the current level and the needs level of TLO (terminal learning objectives) based on the book "Learning outcome of basic medical education: Scientific concept and principle-centered." We conducted a needs assessment utilizing a t-test, Borich Needs Assessment, and the Locus for Focus model. In the investigation of the needs level, the levels of the musculoskeletal and respiratory systems were relatively high and in the investigation of the current level, the levels of the digestive and musculoskeletal systems were relatively high. This study is expected to contribute to reasonable decision-making by utilizing various methods of analysis and providing in-depth results of needs analysis in designing clerkship curriculum.

In this paper, as a liberal arts course for non-majors, we developed a basic practice case for convolutional neural networks, which is essential for designing a basic convolutional neural network course curriculum. The developed practice case focuses on understanding the working principle of the convolutional neural network and uses a spreadsheet to check the entire visualized process. The developed practice case consisted of generating supervised learning method image training data, implementing the input layer, convolution layer (convolutional layer), pooling layer, and output layer sequentially, and testing the performance of the convolutional neural network on new data. By extending the practice cases developed in this paper, the number of images to be recognized can be expanded, or basic practice cases can be made to create a convolutional neural network that increases the compression rate for high-quality images. Therefore, it can be said that the utility of this convolutional neural network basic practice case is high.

Background and Objectives: To investigate the role of exosomes from periodontal ligament cells (PDLCs) in bone marrow mesenchymal stem cell (BMSC) migration. Methods and Results: Human PDLCs were applied cyclic tension stretching. Exosomes were extracted from cultured PDLCs by ultracentrifugation, then characterized for their size, morphology and protein markers by NTA, TEM and western blotting. The process that PKH26-labeled exosomes taken up by BMSCs was assessed by confocal microscope. BMSC migration was examined by Transwell assay. Exosomes derived from PDLCs were identified. Cyclic tension stretch application on PDLCs can enhance the migration ability of BMSCs through exosomes. The exosomal miRNA expression profiles of unstretched and stretched PDLCs were tested by miRNA microarray. Four miRNAs (miR-4633-5p, miR-30c-5p, miR-371a-3p and let-7b-3p) were upregulated and six (miR-4689, miR-8485, miR-4655-3p, miR-4672, miR-3180-5p and miR-4476) were downregulated in the exosomes after stretching. Sixteen hub proteins were found in the miRNA-mRNA network. Gene Ontology and KEGG pathway analyses demonstrated that the target genes of differentially expressed exosomal miRNAs closely related to the PI3K pathway and vesicle transmission. Conclusions: The exosomes derived from cyclic tension-stretched PDLCs can promote the migration of BMSCs. Alternation of microRNA profiles provides a basis for further research on the regulatory function of the exosomal miRNAs of PDLCs during orthodontic tooth movement.
