This study was conducted to develop a web-based learning contents that assists nursing students' clinical practice on operating room nursing and to examine its learning effects. Based on contents and need analysis, 6 learning modules were developed regarding nursing care in surgical operation and operating equipments. In order to verify the effects of the program, this study employed a quasi-experimental pretest-posttest control group design. Knowledge was significantly higher in experimental group that was enhanced by the web-based learning contents than that of the control group (p<.001). However, there was no significant difference between the two groups in self-directed learning. Experimental group had significantly higher motivation toward learning, which was examined posttest only, compared to control group (p<.001). These results support that the implementation of an web-based learning contents need to be continued as an effective educational material but we need more research to establish how this can be effectively implemented in a students' practicum.

This study was designed to investigate actual conditions of textile design education at technical high school in Korea, and to present possible solutions for improving its effectiveness. Inchon Girl's Polytechnic high School was selected as sample of case study because it was the only school which has textile design major. Survey was done through questionnaire and telephone interview. 100 students, 25 graduates, 8 teachers, and 8 managers of textile industry were involved in survey. The data were analyzed by using frequency, t-test, correlation. Statistical analysis resulted in the following suggestions to be considered for maximizing the effectiveness of the textile design education at technical high schools: First, the curriculum should be flexibly reorganized to come up with trends in the market and demands from industry, and also to stimulate and motivate students into the biggest achievements possible. Second, more weight should be given to practical design subjects which have proved to be preferred by students and industry by reducing class hours for non-design subjects or theoretical subjects. Third, equipments and facilities for practical exercise should be open to students anytime needed so that students can improve their practical skills without any restrictions. Fourth, new teachers having majored in textile design at the university should be employed and the existing teachers should be periodically re-educated to keep abreast with new knowledges and technology. Fifth, The solidarity and the connection between schools and companies should be reinforced, not only to provide graduates with more chances to get a job, but also to make education at schools refreshed and updated.

Wide spread using of mobile and handy electronic apparatus is giving rise to a question on the harmfulness of health and causing troubles when electical and electronic equipments are in use. This paper reports on the experimental results obtained by using a pliable and structured specimen that has a long shape aperture, made of stainless steel fibers. Based on the TEM mode transfer structure that was designed and manufactured through HFSS, we measured electromagnetic shielding effectives, where the network analyzer was applied. We could draw a conclusion from this research that the metal fabric showed a good electromagnetic shielding effect, mainly by means of the good reflex loss at the fiber surface. Even though the material itself possesses a good absorption loss. the specimen revealed that structural factors. e.g.. the shape of the aperture. the size of the aperture, etc., can have a more influence on the shielding effect than the components of material have. A special notice is required for modeling and analyzing the electromagnetic characteristics of metal fabrics, because there exists a strong possibility that multiple reflection can happen on the surface of metal fibers. which can presume a model of fiber bundle and fabric structure.

The purpose of this study was to verify the effect of drive swing on multiple functional wear wearing in golf. The subjects were 6 men ($22.67{\pm}0.82$ yrs, $175.42{\pm}3.42cm$, $78.75{\pm}4.78kg$), who had career each with at least 8 yers golf experience with right-hander. For kinemetical analysis, this study used equipments with 7 motion capture cameras (300Hz) and analysis program (Nexus1.5). The total time of the club head, displacement magnitude of the COM and swing plane were compared of according to functional wear wearing and non-weraing during golf drive swing. The results of the study are as follows. The total time of the club on wearing ($2.18{\pm}0.06sec$) was faster than non-wearing ($2.52{\pm}0.15sec$). Displacement magnitude of the COM on wearing ($4.06{\pm}0.67cm$) was shorter than non-wearing ($5.79{\pm}0.72cm$). Also, swing plane was found to be significantly different of 3 phase excepted BST-DS (back swing top-down swing) phase. AD-BST (address-back swing top) phase on wearing ($13.86{\pm}3.08cm$) decrease more than non-wearing ($20.82{\pm}3.99cm$), DS-IP (down swing-impact) phase on wearing ($6.25{\pm}1.35cm$) decrease more than non-wearing ($7.18{\pm}1.52cm$) and IP-FT (impact-follow though) phase on wearing ($7.93{\pm}2.09cm$) decrease more than non-wearing($9.68{\pm}2.02cm$). The multiple functional wear wearing was contribution to come close for one-plane, a long with consistency and accuracy on golf drive swing.

The purpose of this study was to grasp the consciousness of adolescents about their future in old aged housing. This research was executed with a questionnaire survey method. Data samples were collected from 255 students who finished first grade curriculum in high schools in Chonbuk province and Seoul city. The results were as followed. First, a healthcare plan was very highly recognized by students, and they wanted to live as couples or single in their old age. Second, the respondent students recognized elderly housing as a home for the aged, a silver town and nursing home. 72.1% of the respondents preferred a single detached house as an elderly house form. They preferred an elderly housing district with well provided convenient facilities for daily living. They wanted to live in the country or rest areas for the aged. They preferred an interior space composition with LDK with 2 bedrooms. 52.0% students wanted a neighborhood for their friends to live together. Third, 28.3% of the respondent students thought the appropriate time to move in elderly exclusive housing was 66-70 years old. And when their physical condition worsened or they needed care, they would. want to move into that housing. Also, they wanted the most convenient facility and a medical care facility in elderly exclusive housing. Forth, students' space design needs for elderly were high, more than 4 points. It was especially needed safety in space design, and this grade was 4.56(,53) points.

Most warship combat systems inquire human operator to control several sensor and another equipments as well as decision-modeling. For this reason, many researches with multi-agent based M&S (Modeling and Simulation) have been increasingly conducted. However there cannot find any researches of M&S based analysis for anti-submarine warfare that requires a high level of mission complexity between multiple platforms. In this research, we have been developed various combat platform models such as warship, submarine and helicopter, etc. In order to apply the multi-agent-based M&S technology to the anti-submarine warfare i.e. a HVU (High Value Unit) escort mission scenario. Then we have successfully analyzed the measures of effectiveness according to the different tactics and different situations. In future, the defence engineer maybe employ our methodology and tools to analyze actual tactical problem by simply inserting actual data into our agent model.

Since the lack of the spent fuel storage capcity has been expected for all Korean nuclear power plants in the mid-1990s, the maximum density rack (MDR) with consolidated fuels can be proposed to overcome the shortage of the storage capacity in KNU 9 & 10 which have most limited capacities. To ensure the safety when the alternatives are applied in the KNU 9 & 10, the multiplication factor are calculated with varying the rack pitch and the thickness of consolidated storage box by the AMPX-KENO IV codes. The computing system is verified by the benchmark calculation with criticality experiments for arrays of consolidated fuel modules, which was reported by B & W in 1981. Also an abnormal condition, i.e. malposition accident, is simulated. The results indicate that the KNU 9 & 10 storage pools with consolidated fuel are safe in the view of the criticality. Thus the storage capacity can be expanded from 9/3 cores into 27/3 cores even with considering equipments and cooling spaces.

Physical models of underground mines are very useful to the design of mine openings and the management of work progress of mining companies as well as to consulting. Even though 3D image realization techniques for mine openings have already been developed by various companies the physical models are still widely used because they can provide better understanding without sophisticated equipments for the most of people. Conventional materials for the physical models are paper and acryl which demand a lot of time and labor to make the model even with low precision and high cost. In this research, 3D printing technique is adopted to develop the physical model with relatively short time, low cost, and proper degree of precision. Finally the computer software "UMine2STL" was developed and verified by comparing the printed product with its design.
