Korean Ministry of National Defense has criteria for military facilities but most were made with the focus on design criteria of facilities and especially in the case of information and communication, only overall criteria with the level of conceptual design are suggested without details. By comparing the design standards of ICAN and I3A that are applied in US Department of Defense, this study will suggest the desirable design standard of Korean military on command/control facilities and general/administrative facilities.

Purpose: This study was done to investigate the status of disinfection and sterilization in healthcare facilities. Method: A survey of 193 Korean healthcare facilities was conducted from February 8 to March 7, 2013. Data were analyzed using descriptive statistics, ${\chi}^2$ test, Fisher's exact test, one-way ANOVA, Scheffe with SPSS WIN 18.0. Results: Of the healthcare facilities 93.2% had specific guidelines for disinfection/sterilization, but only 47.9% had a committee on disinfection/sterilization for decision-making, less than half (42.7%) conducted regular monitoring of actual practices, while 83.9% had established procedures for recovery in case of problems with the disinfection process and 89.0% kept records and archives of disinfection practices. Cleaning process, selection of chemical disinfectants and process of disinfection and sterilization were found to be inadequate in some healthcare facilities. Perception score for adequacy of medical instruments was 8.10, environmental disinfection was 7.20, and sterilizer management was 8.45 out of a possible 10. Conclusion: Compared to larger institutions, smaller healthcare facilities had less effective disinfection and sterilization management systems, while some facilities showed inadequate practices for medical equipment and general sterilization. Better academic and state-level support is recommended for smaller facilities in order to establish a better system-wide management system.

The snow control storage facilities have the physical requirements that are an anti-icing and deicing operations. They are efficiently and quickly performed, and composed of a vehicle depot for the snow removal equipment and truck, anti-icing and deicing chemical storages, and the control utilities. This study is to investigate the planning guidance of foreign countries, and the actual conditions of the snow control chemical storage facilities for expressway, the national highway and the local road, and is to suggest the planning guidelines. As some of the authorities have no fixed structures for the snow control storage, this study analyze the 5 cases constructed lately. From the result of the case studies, the operations performed in the snow control storage facilities and drawback of the facilities are analyzed with respect to layout, size, plan, and structure, and the improvement planning guidance is also suggested.

This study examined the effect of the distance Infection Control Education Program (ICEP), developed based on the ADDIE model, on infection control knowledge, attitude, and performance among care workers in long-term care facilities nationwide. The program, developed based on the ADDIE model, was applied to 173 care workers directly responsible for nursing care of elderly residents in lomg-term care facilities. The distance ICEP for care workers was conducted through the website and lasted 30 minutes for each of the eight topics. To determine the effectiveness of the education, infection control knowledge, attitude, performance, and satisfaction were surveyed before and four weeks after the program. Differences in infection control knowledge, attitude, and performance before and after the distance ICEP were assessed by a t-test. A significant difference was observed in knowledge and infection control performance after the distance ICEP was administered to care workers. In the sub-domains of infection control performance, overall understanding of infection, regular infection control education, infection control by special pathogen (multidrug-resistant bacteria, tuberculosis, tick-borne infectious diseases), and detailed infection control education by infection site (pressure ulcers and urinary tract infections) were significantly improved. Infection control knowledge and performance improved through the distance ICEP applied to care workers. Satisfaction also displayed high scores on most items and indicated that it was helpful for infection control in facilities, confirming the effectiveness of infection control education. Based on the survey of care workers nationwide, the infection education program can be effectively used for care workers in the future.

To deal with the water pollution arising from the construction site, this study raises the issues of management and laws and it suggest the efficient way to reduce water pollution by through the case studies. In order to study, seven cases were selected from "Construction Environmental Management Best Practice Competition" co - sponsored by Construction Association of Korea and Construction Environment Association. As a study result, there are problems that depending on the characteristic of the construction site environment simple alone settling facilities can not handle muddy and dirty water generated by the construction site. However, when the construction site applied improved water pollution control facilities with reflecting the characteristic of muddy and dirty water. The problem can be solved moreover it can achieve exceeded emission standard. Therefore new regulations and management with water pollution control facilities considering characteristic of environment is needed to cope with water pollution arising from the construction site.

The KSLV-I satellite launch vehicle will be launched in a space center currently under construction. The Space Center which is an advance post base of space development of Korea is located on Oenaro island in Kohung, South Cholla Province. A Ground Complex of the Space Center consists of an AC(Assembly Complex), a LC(Launch Complex), and a MCC(Mission Control Center). Assembly and test facilities are located in the AC in which stage assembly, integrated assembly, check-up, certification test, and pre-launch test are made effectively. A launch pad, fuel supply facilities, a launch control center and associated supporting facilities are located in the LC, and the MCC has control over the space center. These ground complex facilities have diverse forms of an interface with mechanical device, electric device, and etc. These should also provide optimum condition and performance during launch operation processes of the launch vehicle. This paper introduces the result of R&D for the AC of the ground complex performed during system design period.

Sludge quantity has increased at "A"water treatment plant due to deterioration of raw water quality and GAC installation. Increased sludge resulted in overloading on sludge handling facilities. The object of this study is to survey sludge quantity and capacity of sludge handling facilities at "A"water treatment plant. Measured quantity of sedimentation sludge considerably exceeded the design capacity of sludge holding basin. Sludge holding basin was properly designed, but low concentration of sludge discharged from sedimentation basin caused production of large volume of the sludge. Timer operated control system for sludge withdrawal unit and leakage through a control valve were suspected to cause the low concentration. Augmentation of the control system by a turbidity meter and addition of a new control valve successfully reduced the sludge volume enough to satisfy the design capacity of sludge holding basin. Unlike sedimentation sludge, measured quantity of washwater was considerably less than the design capacity of washwater basin because it was over-designed.

Recently, many water treatment facilities are operated by automatic control or by remote control. These high technology control systems require more stable power supply than before Badly most automatic control systems adopted in water treatment facilities are non-linear load which generates electrical harmonics inevitably. This study is intended to measure and analyze the electrical harmonics occurred at the chemicals control device which is inverter application circuit. and to show the effect of the harmonics filter.
