The aim of this research is to understand the characteristics and status of existing public facilities, in order to propose the necessary basic materials for the planning and development of improved public facilities to assist communities. Objects of this research are the public facilities provided by the Government throughout the 25gu in Seoul. The methods of this research were carried out through the home page of each facility, telephone inquiries and gujung backseo. Investigations were carried out 3 times between the periods of January-June and September in 2009. Results of the research are as follows - 1) Through the investigations of classifications and distribution status of 5 public facilities over 25gu, quantity supply problems were analyzed. 2) Building distributions of 5 public facilities were classified by types and analyzed. 3) A number of compound facilities were classified and analyzed to determine the complexities of the 5 public facilities. 4) Complex types and characteristics of public facilities in 25gu in Seoul were analyzed. Based on the results of the research, the following conclusions are drawn: 1) Public facilities throughout the 25gu in Seoul have common characteristics and functions and they are spread out evenly in each gu. This means that public facilities are standardized in Seoul. Characteristic public facilities suitable to each gu should be planned accordingly. 2) Public facilities in Seoul show a single form of one facility. Therefore, initiative plans for the complexity of facilities are required. 3) Complex public facilities in Seoul need to be the center of community life in each gu. It is necessary to take into account the diverse life styles and classified needs of residents for complex facilities. Based on the research, complex types such as public administrative+cultural facilities, culture+welfare facilities, medical+welfare facilities can be presented. These complex types should not be classified according to any particular use, but they should be commonly used by diverse generations and every social class. The inquiries of users of public facilities and the programs of each public facility are not included in this research. Thus, the reseaarch limits the proposals for complex public facilities. In the future, the characteristics of each gu in Seoul should be studied and understood, so that appropriate public facilities and their complex plans can be researched continuously and necessarily.

This paper introduces facility operation modeling and simulation based primarily on a discrete event system modeling scheme. Many modern industrial facilities are so complex that their operational status cannot be estimated by simple calculations. In general, a facility can consist of many processes and transfers of material between processes that may be modeled as a discrete event system. This paper introduces the current status of studies on operation modeling and simulation for typical nuclear facilities, along with some examples. In addition, this paper provides insights about how a discrete event system can be applied to a model for a nuclear facility. A headend facility is chosen for operation modeling and the simulation, and detailed procedure is thoroughly described from modeling to an analysis of discrete event results. These kinds of modeling and simulation are very important because they can contribute to facility design and operation in terms of prediction of system behavior, quantification of facility capacity, bottleneck identification and efficient operation scheduling.

Among the dyeing industries, the tenter process is a process that improves the quality of fibers by drying and ironing (heat treatment) dyed fabrics, and drugs such as water repellents, antistatic agents, and fiber softeners are mainly used in these tenter processes. These drugs are vaporized in the process of treatment by high temperatures (180 ~ 230℃), and are observed in a complex form such as white smoke, oil mist, and fine dust, causing odor. To treat the complex exhaust gas at the rear end of the tenter facility, most companies operate by installing a wet scrubber and an adsorption tower alone or in parallel, but there are many problems. In particular, the insoluble oil mist at the rear end of the tenter has significantly low processing efficiency in the cleaning dust collection facility, and there is a problem in the facility by adsorption due to the occlusion phenomenon caused by the oil mist. In addition, the odor gas at the rear end of the tenter contains a lot of aldehydes, and in order to improve these various problems, a complex exhaust purification device using cyclone and electric support collector was developed. This study examined the applicability of economical and efficient technology by removing complex air pollution at the rear end of the tenter and applying improved technology than the existing technology.

Objectives: Using atmospheric dispersion representative models (AERMOD and CALPUFF), the emissions characteristics of each model were compared and analyzed in ready-mixed concrete manufacturing facilities that generate a large amount of particulate matter (PM-10, PM-2.5). Methods: The target facilities were the ready-mixed concrete manufacturing facilities (Siheung RMC, Goyang RMC, Ganggin RMC) and modeling for each facility was performed by dividing it into construction and operation times. The predicted points for each target facility were selected as 8-12ea (Siheung RMC 10, Goyang RMC 8, and Gangjin RMC 12ea) based on an area within a two-kilometer radius of each project district. The terrain input data was SRTM-3 (January-December 2019). The meteorological input data was divided into surface weather and upper layer weather data, and weather data near the same facility as the target facility was used. The predicted results were presented as a 24-hour average concentration and an annual average concentration. Results: First, overall, CALPUFF showed a tendency to predict higher concentrations than AERMOD. Second, there was almost no difference in the concentration between the two models in non-complex terrain such as in mountainous areas, but in complex terrain, CALPUFF predicted higher concentrations than AERMOD. This is believed to be because CALPUFF better reflected topographic characteristics. Third, both CALPUFF and AERMOD predicted lower concentrations during operation (85.2-99.7%) than during construction, and annual average concentrations (76.4-99.9%) lower than those at 24 hours. Fourth, in the ready-mixed concrete manufacturing facility, PM-10 concentration (about 40 ㎍/m³) was predicted to be higher than PM-2.5 (about 24 ㎍/m³). Conclusions: In complex terrain such as mountainous areas, CALPUFF predicted higher concentrations than AERMOD, which is thought to be because CALPUFF better reflected topographic characteristics. In the future, it is recommended that CALPUFF be used in complex terrain and AERMOD be used in other areas to save modeling time. In a ready-mixed concrete facility, PM-10, which has a relatively large particle size, is generated more than PM-2.5 due to the raw materials used and manufacturing characteristics.
