The environment of underground spaces might be considered in view of working environment during the construction and living environment after completion of the construction work. For controlling environment of underground space, an appropriate measures have to be taken on the governing factors such as air flow, dust, gases, heat, radiation, noise, illumination and water. The more critical matter, in underground environmental point of view, is underground disasters such as fire, gas explosion and water inrush. This paper presents the general introduction of these factors mentioned above and some outcomes of research works as of now.

The study is to probe a technical alternative to enhance the reliability and accuracy of the results of various landscape simulations. This study to present technical criteria that are necessary in each stage of target site analysis, picture taking, and computer synthesis and, through these to present supplementary plans to enhance the reliability and accuracy of landscape simulations. In order to derive more practical and empirical results in terms of the reliability of the results of landscape simulations, examples that actually passed landscape review were selected. With regard to study process, an analysis was made first to analyze the landscape report data of designs that passed the review to analyze their characteristics, to be followed by an integrated analysis of problems that were revealed in various landscape simulations. Important factors that affect directly the work of landscape simulations such as the specification of camera lenses that were used in picture taking, distance, and angle. Design the work was carried out using Auto CAD, 3DS Max, and Photoshop program in the same way as in actual design. For verification of their accuracy and reliability, the results were entrusted to experts who have implemented similar jobs. To seduce differences from those too landscape simulations that conduct trial experiment of the virtual space that are to be created in the future with accurate numerical values.

This study focused on the expression technique and work manufacturing of nail design. Any woman that wants to be pretty is interested in nail design which is considered as a means to express beauty, intelligence and sensuality. These days, nail design carries heavy weight in completion of total fashion coordination. Good dress, elegant hair style, bright make-up and well-trimmed nails are requirements of modem women. These days, the range of nail design is more expanding and its importance is getting bigger. To maintain and establish such developmental flow properly, we have to break our stereotyped view on nails and accept it in open view. And we have to actively participate in development of new products and technologies and perform academic research on nail design. For the purpose, we have to consider further studies which contribute to understanding exact meaning of nails and necessity and importance of nails.

In this work, we propose a compression algorithm for depth images, which are obtained from multi-view sequences. The proposed algorithm represents a depth image using a 3-D regular triangular mesh and predictively encodes the mesh vertices using a linear prediction scheme. The prediction errors are encoded with a arithmetic coder. Simulation results demonstrate that the proposed algorithm provides better performances than the JPEG2000 lossless coder.

Purpose: The purpose of this study is to help care workers to do their best as first respondents by analysing their recognition, knowledge, and self-efficacy on basic CPR (cardiopulmonary resuscitation) that is directly connected to the lives of patients and thus their education and methods can be improved for their positive basic lifesaving work. Method: For this purpose 360 structured questionnaires were used to the subjects in the eastern area of Jeonnam province from June 20 to July 4, 2011. Of these questionnaires 217 were used excluding 113 incomplete, 27 error, and 3 male ones. The collected data were analysed by the real number, the percentage, the average, the standard deviation, t-test, ANOVA, and Tukey with SPSS WIN 18.0. Results: 1. In the view of subjects, those aged over 51 accounted for 96(44.2%) as the majority, high school graduates, 95(43.8%), worked for 1 or more than 1 year-less than 2 years, 66(30.4%), experienced to see persons collapsed losing their consciousness, 46(21.2%), took the education, 184(85.7%), had 1 session of education, 80(43%), got the last education for 2 or more than 2 years 68(37%), and practiced through mannequin for the education aids, 86(46.7%). 2. There was significant difference in the view of recognition with the length of work (p=.010) and experienced to see persons collapsed losing their consciousness (p=.020), in the view of knowledge with academic background (p=.040) and the length of work, and in the view of self-efficacy with academic background (p=.002), the length of work (p=.010) and experienced to see persons collapsed losing their consciousness (p=.000). 3. There was significant difference in the session of education (p=.000), last education (p=.025) and education aids for basic CPR. Self-efficacy had significant difference according to the session of education for basic CPR (p=.001) and the time of education (p=.000). 4. There was correlation between recognition and self-efficacy (r=.41). The higher the recognition is, the better the self-efficacy improves. However the correlation between knowledge and self-efficacy was so low that the former did not have influence on self-efficacy. Conclusions: It needs to offer education to the lifesaving workers based on their experiences. If there is education more than 2 sessions in a year with mannequin and the simulation providing sufficient hours, care workers' recognition would be increased resulting in higher self-efficacy and thus they could keep the role of active lifesaving worker at the first practical site.

The aim of this study is to propose the criteria for a evaluation model of the lifetime household work and organize the model. The results were as follows: Three criteria for a evaluation model of the life-time household work were proposed. $\circled1$ An appropriate framework of the evaluation model should be based on the transition of the family life. $\circled2$ The model should include major variables influencing the value of household work of homemaker. $\circled3$ The model should be flexible enough to accommodate various evaluation methods, and should reflect idiosyncracies of different evaluation methods. In view of the criteria stated above, the present study is based on the family life cycle framework. And the age of the last offspring exhibits a consistent major influence in the evaluation based on the household work hours, while the education level of homemakers shows a consistent major influence in the evaluation based on household worker. So as to reflect these two major variables in the family life cycle framework.

The majority of small/medium sized shipbuilders in Korea is poor in capital and then, should be restructured as an efficient production system with low investment. Due to considering this situation, the cooperative work system is proposed, in this study, as more effective production system for small/medium sized shipbuilder The cooperative work system Is the production system that many small/medium sized shipbuilders in a group jointly share the common facilities except minimum equipments and have managerial cooperation such as joint purchase of raw materials. The efficiency of cooperative work system is proved from economic and technical point of view with the case study of FRP shipbuilders of Sapjin industrial complex located at Mokpo area.

Recently, instead of a high-cost supercomputer, there haws been widely used a NOW system that consists of low-cost PCs and workstations connected all over the network In a NOW, performance for parallel processing depends on the computation pouter of each computer and communication time. Currently, a lot of methods have been proposed in order to increase the performance of parallel processing. However, the previous results have been studied in the view of balancing work load as the computation pouter of each computer. If a computer has multiple work precesses in a NOW, we can predict a decrease of communication tire needed in message passing, Therefore, in this paper, we analyzes factors of improving the performance in the view of work precesses, and evaluates experimently an effect on total performance as the number of work processes increases. Also, we propose a new broadcasting method to be used in experiment of this paper. This paper uses the LAM/MPI for an experimental evaluation.
