With the advent of the time when the competitiveness of a nation or a city can be evaluated by the extent of cultural reception, the art exhibitions, like other genres of art, are actively held in various ways by different institutions. The spaces of exhibition offered not only by public museums and galleries but also by private galleries, alternative spaces and open-air exhibition spots are being increased. Likewise, the number of exhibitions organized on a large scale by Biennales and local governments is on the increase. In accordance with actual tendency, the Ministry of Culture and Tourism has planned to increase the number of museums and galleries up to 500 by the year of 2011. Under these circumstances, the actual situation shows that the central and local governments are adopting beneficial measures to support the private galleries such as permission of construction on green belt areas and tax deduction. That is, our society has come to realize that the necessity and importance of public as well as private galleries to play their roles as cultural and educational institution. Now, the number of galleries is growing. Exhibitions are held everywhere. Therefore, spectators have more chance to visit them than before. With these conditions and the growing number of amateurs, social interest in curator organizing exhibitions is getting popular. Because of the rise of curatorial popularity on the social level, the influence of curators which is exercised within the gallery seems to become gradually enlarged. In reality, it is true that the curatorial influence cannot be ignored more than ever for appear in various fields their new features made from their professional cometence. The function of gallery is more strengthened and its position is more heightened than those in 80s. For these reasons, the curators whose playground is the gallery, they may be regarded as invisible power to the artists. Futhermore, their influence as such seems to be more likely because our world of art does not still have any reliable system of art criticism. Nevertheless, considering the actual situation in which national and public galleries as cultural institution would rather exist on the local sentiments or political dynamics than on autonomy, there must be some restrictions for the galleries and the curators to obtain the power. In this context, the actual moment is looked upon as transitional period to make the curatorship settled down. Before discussing the power relevant to curatorship, we are going to examine first the role and function of curator and then the new curatorial role and function at the age of information. Finally, we will see in sequence the development and problems of curatorship, the power and dilemmas of curator.

The subjects were recruited women from Wonju city 18 years or older. 1. The results showed that about 50% of the women were satisfied with their lives as women, 23% of the sample felt there was a need for a women's health care center. The mean number of health problems was 3.1 and the prevalence rate, 44.4%. 2. We developed on educational program according to group differences related to health problems, diagnosis of disease, variables influencing health promotion behavior, and programs which each group wanted. Also we stressed self-efficacy and self-help group for the management of individual health to all groups. 3. The diagnoses of diseases that were experienced premarital over the past year were gastritis, bronchitis, spinal disk, and fracture, for the childbearing/rearing group, gastritis, vaginitis and cervicitis, cervical cancer and cystitis and nephritis and arthritis and for the middle-aged/elderly group arthritis, gastritis, vaginitis and cervicitis, and spinal disk. Of the sample 30.5% did not have a health exam in the past year, and only 10% of the premarital group, 12.5% of the childbearing/child-rearing group, and 18.3% of the middle aged-elderly group were concerned about their health and did something for their health. 4. The average score on the HPLP was 2.41. the HPLP was scores according to group were found to have significant differences. self-efficacy, family functions, health attention and were considered important variables in the premarital group, in the childbearing/child-rearing group self-efficacy, family functions, internal locus of control, health attention, and health perception and power others locus of control and then for the middle aged-elderly group self-efficacy, health attention, internal locus of control, family functions and health perception. 5. There are a few educational programs in the city provided by the Wonju Health Center and by community health nurse practitioners. The premarital group requested the educational programs on diet, health exercise, family health and stress management. Also the childbearing/child-rearing group wanted programs on diet, family health, stress management, and health exercise, and the middle-aged/elderly group wanted that of family health, diet, climacteric changes stress management and health exercise. The program suggested that this program should be applied to women in the community to insure adequate management of women's health. Follow-up research with PROCEED is needed to analyze health outcomes, also, a women's health nursing specialist system is required to develop health promotion, and improve the quality of life for women.

Although planning techniques linking parks, green areas, and waterways have become common, there are frequent disruptions in the operation and management of landscape-use artificial channels (LuAC). Therefore, this study examined a design to promote the sustainable management and operation of a LuAC using rainwater for the streamlets of the Jeonju-Wanju Innovative City. In order to accomplish the purpose of this study, scenarios were set up by dividing the design into waterhead and waterway portions. First, the scenario regarding the waterhead was analyzed to calculate the water supply and storage required for the waterway and waterhead. The analysis showed that the waterway requires a water supply of 676.8 tons/months, 3,018 tons to 5,512 tons of storage space, and a water depth of 0.75 m to 1.37 m considering the ecological and landscape aspects. The second scenario is to select an effective system of facilities for the operation and management of the LuAC. To accomplish this, a single-circulation system (SCS), which transports water to a highland location was compared to a multi-circulation system (MCS), which supplied water separately to each water space and operated independently. The results showed that the MCS, which was operated independently by small power units, was more effective owing to the vast difference in water supply operation times.

Celestial Chart Stones (original and reproduction) in the National Palace Museum are representative scientific cultural heritage of Korea. Material analysis and nondestructive deterioration assessment were conducted for long-term preservation of these stones. Material analysis revealed that the original was composed of slate and the reproduction was made of dolostone. The original consists of quartz, mica, dolomite minerals, while the reproduction was made up of dolomite, calcite and forsterite. Major deterioration factors of the original stone were cracks and breakouts. In case of the reproduction, scratches and artificial materials were mainly observed. The green and black surface contaminants present at the sides and back of the two celestial chart stones were interpreted as resin-based paint materials. The physical property evaluation using ultrasonic velocity showed a low velocity in the upper left side of the original, while the front right side of the reproduction showed a weak property. Meanwhile, the To-Tc method using ultrasonic velocity was applied to major cracks that impede stability of the original. As a result, it has been calculated that the beginning and the center of the crack are the deepest.

Regenerative orthopedics needs significant devices to transplant human stem cells into damaged tissue and encourage automatic growth into replacements suitable for the human skeleton. Soft biomaterials have similarities in mechanical, structural and architectural properties to natural extracellular matrix (ECM), but often lack essential ECM molecules and signals. Here we engineer mineralized polysaccharide beads to transform MSCs into osteogenic cells and osteoid tissue for transplantation. Bone morphogenic proteins (BMP-2) and indispensable ECM proteins both directed differentiation inside alginate beads. Laminin and collagen IV basement membrane matrix proteins fixed and organized MSCs onto the alginate matrix, and BMP-2 drove differentiation, osteoid tissue self-assembly, and small-scale mineralization. Augmentation of alginate is necessary, and we showed that a few rationally selected small proteins from the basement membrane (BM) compartment of the ECM were sufficient to up-regulate cell expression of Runx-2 and osteocalcin for osteoid formation, resulting in Alizarin red-positive mineral nodules. More significantly, nested BMP-2 and BM beads added to a non-union skull defect, self-generated osteoid expressing osteopontin (OPN) and osteocalcin (OCN) in a chain along the defect, at only four weeks, establishing a framework for complete regeneration expected in 6 and 12 weeks. Alginate beads are beneficial surgical devices for transplanting therapeutic cells in programmed (by the ECM components and alginate-chitosan properties) reaction environments ideal for promoting bone tissue.

This study would suggest a measure for the improvement of the commentary program on the building concentration area of Changdeokgung Palace. In the process of the survey, the researcher attended the commentary site and tape-recorded commentaries two times. The researcher conducted an analysis of the times and contents of the tape-recorded commentaries and evaluated their appropriateness, including historicity and connectivity to the site. In addition, the researcher figured out the commentaries and the visitors' movements through drawings and field surveys and analyzed the locations and conditions of the main facilities. Through a field survey and analysis, it was found out that the commentaries included the facts and anecdotes about the buildings, the related figures and history. However, it was found out that there were very insufficient commentaries on the buildings arranged according to the commentary movements, the outside space, in particular, the traditional landscape facilities. In addition, it was found out that there are areas that would need commentaries and opening for viewing. A proposal for the improvement of the commentary program was drawn up based on the analysis. New commentary points were added, and the commentaries of the outside space of the area and the traditional landscape facilities could improve through modifying the existing commentaries. With the proposal for improvement, the time required was calculated through reading aloud at a speed the same as the existing commentary speed. Through this, it was found out that the proposal for improvement could be implemented within one hour, the same as the present commentary program. This study has a significance that it provided a measure for practical improvement that could provide the visitors with quality commentary information and more interesting experience.

Hybrid power storage system with emergency power function for demand management and power outage minimizes the investment cost in the building of buildings and factories requiring emergency power generation facilities, We propose a new business model by developing technology that can secure economical efficiency by reducing power cost at all times. Normally, system power is supplied to load through STS (Static Transfer Switch), and PCS is connected to system in parallel to perform demand management. In order to efficiently operate the electric power through demand forecasting, the EMS issues a charge / discharge command to the ESS as a PMS (Power Management System), and the PMS transmits the command to the PCS controller to operate the system. During the power outage, the STS is rapidly disengaged from the system, and the PCS becomes an independent power supply and can supply constant voltage / constant frequency power to the load side. Therefore, it is possible to secure reliability through verification of actual system linkage and independent operation performance of hybrid ESS, By enabling low-carbon green growth technology to operate in conjunction with an efficient grid, it is possible to improve irregular power quality and contribute to peak load by generating renewable energy through ESS linkage. In addition, the ESS is replacing the frequency follow-up reserve, which is currently under the charge of coal-fired power generation, and thus it is anticipated that the operation cost of the LNG generator with high fuel cost can be reduced.
