Some studies require sufficient amount of time, spaces, and financial condition for practical exercises and training. In particular for the Medical education, time and space limitation is very high and difficulties occurs, since the practices are done with cadavers (deceased human body). Many alternate 3D Virtual surgery training system exist currently, however the burdensome of obtaining those costly equipments is problematic. Providing the surgical environment as similar to real as possible using 3D Virtual Reality can be a solution to current problems. The effectiveness of training could be maximized with minimized costs without the general interfaces such as keyboard and mouse, but with Oculus Rift and Leap Motion. This paper will develop and practice the 3D Virtual Operation System with two devices to investigate the possibility and expand to other Simulation fields.

This study evaluated on the recognition and satisfaction for functional bakery products by consumers living in Seoul, Overall, 82.0% answered of the respondents reported that they had 'yes' which was 4.5 times as much as those who answered 'no' tried functional bakery products. Purchasing mostly depended on 'myself' (69.0%), and other methods of acquiring information as well as 'bakery' (10.8%), 'neighbour' (8.5%), 'media' (7.9%), and the 'internet' (3.7%). The preferred functional ingredients were 'sweet potato' with (22.9%), and 'rye and oat' (13.8%), 'green tea' (13.5%), 'pumpkin' (11.4%), and 'chestnut' (7.3%) were other preferred ingredients. The reasons for this preference were that they were 'healthy' by (47.1%) and had a 'good taste' by (36.6%). Evaluation of the recognition of functional bakery products revealed that, 'nutrition' had the highest scale of recognition of (3.80 out of 5), and followed by 'healthy' with (3.69 out of 5). Conversely, 'proper price' received a below average score of 2.97, indicating dissatisfaction. Moreover, the overall average satisfaction with functional bakery products was 3.37, and with the taste, nutrition, and quality receiving a highly satisfactory score of 3.52, and price receiving an unsatisfactory score of 3.00. The factors most important to improve functional bakery products were, 'variety' (37.6%) was most important, followed by 'increased nutrition' (21.2%) and 'lower price' needed to be improved as well. The factor that had the greatest influence on the decision to purchase functional bakery products was 'material' with (3.737) followed by 'name value' with (3.56).

This study investigated the demand of nutrition education programs among preschooler's parents. Focus group interview was conducted four times with 29 parents of preschool children. Most subjects appeared to have interest in nutrition education; 'very interested' (58.6%), 'somewhat interested' (20.7%). Sources of nutrition information were 'internet' (35.1%), 'books' (21.6%), 'newspaper or magazines' (13.5%), 'family or relatives' (13.5%), 'media' (8.1%), 'preschool' (5.4%) and 'hospital or public health center' (2.7%) in order. The most frequently mentioned health problems related to dietary behavior were atopy and obesity. Major concerns for children's dietary behavior was picky eating habits, and having questions for how to deal with this problem. Most subjects had trouble with obtaining an adequate amount of dietary supplements for their children. Nutrition education for parents about food labeling and information on processed foods was in demand. Preferred methods of nutrition education for children were playing games with stickers, gardening vegetables, and participating in cooking. Attitudes toward computer-assisted education materials, one of the methods of nutrition education, appeared to be ambivalent. Some preschool parents showed negative attitudes towards exposing their children to electronic devices at an early age, whereas others showed positive attitudes. Subjects were interested in meal-planning and ways to balance nutrients for their child. Parents preferred attending professional lectures to receive reading materials or searching websites as an adult nutrition education method. Results of this study have implications on providing basic information for developing nutrition education programs for preschoolers and their parents. Future research should focus on developing nutrition education programs for both preschools and the home.

This study examined consumers' perceived anxiety regarding how safe the clothing and lifestyle products are as well as influencing factors. Data was collected using a self-ministered online survey of 1,126 adult consumers. The results of this study showed that consumer anxiety about chemicals and hygiene product safety had a greater impact on the anxiety perception of general safety than clothing and beauty products. It was confirmed that the reliability of information source (government agency, mass media, expert group, and internet community/blog) varies depending on the level of consumers' overall safety anxiety. The study also found the effect of consumers' subjective perception of health on safety anxiety about clothing and lifestyle products. Further, the moderating effect of age in the research model was confirmed. This result can be a useful guide to marketing communication for developing consumer safety-related policies to reduce consumer anxiety. The information will also help consumers make informed decisions that lead to safe and sustainable consumption.

We see an energy fucused smart city evolution of the UK along with the project of "Smart London Plan (SLP)." A theoretical logic of business model innovation has been discussed and a research framework of evolving energy focused smart city is formulated. The starting point is the silo system. In the second stage, the private investment in smart meters establishes a basement for next stages. As results, the UK's smart energy sector has evolved from smart meter installation through smart grid to new business models such as water-energy nexus and microgrid. Before smart meter installation of the government, the electricity system was centralized. However, after consumer engagement plan has been set to make them understand benefits that they can secure through smart meters, the customer behavior has been changed. The data analytics firm enables greater understanding of consumer behavior and it helps energy industry to be smart via controlling, securing and using that data to improve the energy system. In the third stage, distribution network operators (DNOs)' access to smart meter data has been allowed and the segmentation starts. In the fourth stage, with collaboration of Ofwat and Ofgem, it is possible to eliminate unnecessary duplication of works and reduce interest conflict between water and electricity. In the fifth stage, smart meter and grid has been integrated as an "adaptive" system and a transition from DNO to DSO is accomplished for the integrated operation. Microgrid is a prototype for an "adaptive" smart grid. Previous steps enable London to accomplish a platform leadership to support the increasing electrification of the heating and transport sector and smart home.
