This study aims to define concepts on Hospital Design Focused on System to respond to the development and change by comparing general design methods of the General hospital architecture in Korea and analyze elements suitable to concepts on Hospital Design Focused on System in the General hospital architecture through examining the transformation of General hospitals in Korea. Essential architectural elements composing the Hospital Design Focused on System are as follows. First of all, the elements which can react to development of hospital architecture are HOSPITAL STREET and site situation. Secondly, core, equipment shaft, column, MAIN STREET and air handling unit room are elements of great importance as the location of these elements determines the dimensions and scale of the space which hospital functions are assigned to. Third, the area in regard to the rate of change is formed by MAIN STREET, which is the primary element, and envelope. The depth between MAIN STREET and envelope is defined as space depth. The flexible area is determined depending on this space depth and thus how to set up this flexible area determines the degree of readiness in responding to the change.

Pyrophosphoric lactone modified polyester(PATT) that contains two phosphorous functional groups in one unit base resin structure was synthesized to prepare a non-toxic reactive flame retardant coatings. Then the PATT was cured at room temperature with isocyanate, Desmodur IL, to get a two-component polyurethane flame retardant coatings(PIPUC). Comparing the physical properties of the films of PIPUC with the film of non-flame retardant coatings, there was no degradation observed in physical properties by the introduction of a flame-retarding component into the resin. We found that the char lengths measured by $45^{\circ}$Meckel burner method were $3.1{\sim}4.4cm$ and LOI values recorded $27{\sim}30%$. These results indicate that the coatings prepared in this study is good flame retardant one. The surface structure of coatings investigated with SEM does not show any defects and phase separation.

The PV-Solarwall system has been introduced as a promising alternative to harness solar energy for both heating applications and electricity generation simultaneously. The system comprises a PV solar panel(for electricity generation). In addition, the solarwall incorporates a fan strategically located behind the PV panel to bring the warm and fresh air from the solarwall into the room. Because of its location and convective cooling principle, the fan also serves to reduce the operating temperature of the PV panel thereby increasing its efficiency. So this PV-Solarwall system holds much promise for saving heating and electricity costs compared with a PV system without solarwall. In particular, by controlling the tilt angle of the entire PV-Solarwall system between $0^{\circ}$(horizontal) and $90^{\circ}$(vertical), the performance of the system can be further evaluated. It is expected that the range of tilt angle PV-Solarwall between $40^{\circ}$ and $50^{\circ}$ will improve the output of the system.

Purpose: This study was to compare nursing performance by career levels in a career ladder system. Methods: This survey was conducted with 140 OR staff nurses. Ten unit managers evaluated their own staff with a performance evaluation tool composed of 51 items. Data were analyzed by frequency, t-test, one-way ANOVA, ${\chi}^2$-test, and ANCOVA. Results: In career level CN II, nursing performance showed differences by personal characteristics. However, there was no significant difference in level CN III. CN IIIs' nursing performance was significantly higher than CN IIs' in all domains. Nursing performance of CN III was significantly higher than CN IIs' in 5 to 10 years of clinical experience. Although there was no significant difference in other clinical experience groups, CN IIIs' scores were always higher than CN IIs' Conclusion: The results indicate that nursing performance improves with career ladder advancement. Organizations should encourage advancement to higher levels and eliminate obstacles.

Blue light of Cherenkov radiation generated by electrons in transparent substances such as water and acrylic resin is well known generally. If students can easily observe the blue light at school, they may be impressed by the fascinating radiation. Four years ago, management of the Co-60 unit for radiotherapy was transferred to Nagoya University School of Health Sciences from a related hospital. We have examined whether or not the Cherenkov radiation in water from secondary electrons generated by Co-60 gamma-rays can be safely observed by eyes and photographs. First, the Cherenkov radiation in the water tank was led to the corridor outside the irradiation room by a mirror, and observed directly without any effect of the radiation exposure. Second, photographs of the Cherenkov radiation were taken under the conditions consisted of several irradiation fields and pass lengths of gamma-rays in water.
