Vacuum chamber or vacuum tube for the exhaust process of vacuum glazing is presently used, where excessive time and expenses are required to make the whole vacuum chamber or tube vacuum. To solve this problem, multifunction equipment for vacuum exhaust and ultrasonic joining at atmospheric pressure has been developed, in which a piezoelectric vibrator experiences excessive temperature rise resulting in optimizing the cooling of the equipment. Therefore, in this study, cooling effects of natural convection and forced convection methods were identified by numerical analysis and experiments, and cooling performance of the multifunction equipment was optimized.

Exponentially increasing UCC, experiences which some people get at the specific time and in the specific location are shared on the Web more easily. Also, UCC have been more reliable and more efficient resources, because of many people's natural valuation on each UCC. UCC have potential possibility to be primary factor in all ubiquitous computing environment. However, like ubiquitous computing techniques themselves the current availability and utilization of online UCC is far from realizing their full potential. In this paper, we propose a technique that integrates existing methods from information retrieval and tagging technologies to correspond with user's underlying need for some information in ubiquitous computing environment.

Physiological characteristics of Panax ginseng were reviewed in relation to temperature. According to the old literatures and records of cultivator's experiences it was elucidated that ginseng plants require light but hate high temperature and that the cultural methods were developed to content two characteristics in contradiction. Low temperature (cool climate) during growing season seems (or ginseng to be essential and to escape from the extreme coldness according to air and soil temperature of natural habitat and cultivated area. Optimum temperature of dehiscence (15∼below 20$^{\circ}C$) is a little higher than that of germination (10∼15$^{\circ}C$). Optimum temperature for growing of new buds (18∼20$^{\circ}C$) is similar to that for growing after emergence (17∼21$^{\circ}C$). Dormancy of both matured embryo and new buds is broken at the same temperature (2∼3$^{\circ}C$). It seems reasonable that optimum temperature of photosynthesis (22$^{\circ}C$) is similar to that of growth. Respiration quotients of various organs or of whole plant ranged from 1.7 to 3 incrased with high temperature. Respiratory consumption and oxygen limitation seem to be potential factors to induce decay during dehiscence and germination of seeds and root rot in fields. Research on organ differentiation. photosynthesis, respiration and growth with age is needed for the development of cultivation methods.

Purpose: This study was done to evaluate the experience of securing patient safety in hospital operating rooms. Methods: Experiential data were collected from 15 operating room nurses through in-depth interviews. The main question was "Could you describe your experience with patient safety in the operating room?". Qualitative data from the field and transcribed notes were analyzed using Strauss and Corbin's grounded theory methodology. Results: The core category of experience with patient safety in the operating room was 'trying to maintain principles of patient safety during high-risk surgical procedures'. The participants used two interactional strategies: 'attempt continuous improvement', 'immersion in operation with sharing issues of patient safety'. Conclusion: The results indicate that the important factors for ensuring the safety of patients in the operating room are manpower, education, and a system for patient safety. Successful and safe surgery requires communication, teamwork and recognition of the importance of patient safety by the surgical team.

The purpose of this study was to examine the relations between using experience of environmental education facilities and attitude toward environmental education in parents who have elementary students in Seattle, U.S. The findings of this study represented that elementary parents have a great understanding about the importance of environmental education. Parents have a strong agreement with the necessity of environmental education in childhood. This research also found the differences between grades and facilities for environmental education in expected effect on environmental education and desirable fields of environmental education. The awareness of the importance of environmental education increased according to frequency in using environmental education facilities. In addition, the more the experiences of using various environmental education facilities, such as museum of natural history, science museum, arboretum, and aquarium expanded, the more educational effects positively increased over time.

Purpose: The purpose of this study was to explore the monitoring experience of nursing students and to suggest considerations when developing mentoring programs. Methods: This qualitative study was conducted by online surveys and individual interviews with 7 nursing students who participated in the health promotion program as mentors. Data were analyzed using qualitative content analysis to identify motives for participating in mentoring and to explore their changes through mentoring. Results: The results were as follows: Motives for participating were 'inquisitiveness about children', 'interest in mentoring activities' and 'curiosity about research'. Recognition of mentor roles were 'actively involved guide', 'exemplary role model' and 'empathetic emotional supporter'. Changes through mentoring experiences were revealed by 'understanding the characteristics of children', 'improvement of interaction ability with children', 'understanding self and changes' and 'recognition of excellence in forest activities'. Conclusion: Nursing students had opportunities to learn the characteristics of general children and to understand themselves through natural interaction. Participation in mentoring has the potential to be a creative educational method of field learning as a form of service learning.

The most wind farm development process in Korea still have not been defined since the history of the wind farm development experiences are very short compared to EU and other developed countries. Therefore, most wind farm development company and researchers have a lot of trouble to implement the wind farm development and need a guideline for the process. Establishing the wind farm needs a complex processes such as transportation system, construction conditions, natural environment and wind conditions etc. Specially, for the restricted development area, the social negotiation and legal minds are necessary. In the case, the decision making process of suitable wind farm area using GIS tool is very useful. However, before using GIS technique, we should understand the development processes and the items for surveying tools. Recently, suitability analysis of selecting Onshore Wind Farm has been studied to consider exclusion analysis to solve the limited develop condition problem. This paper proposed the onshore wind farm development process which can suitable to Korea wind farm environment based on European guideline with GIS tool. To estimate the processes, the processes are divided into two parts, the basic design and wind farm planning. Next, the planning stages are classified into five stages in which the factors for each step were considered.
