Purpose: This study aims to compare 119 emergency medical services (EMS) in South Korea and Japan to provide essential data for EMS improvement in South Korea. Methods: Recent data and regulations on firefighting and EMS in South Korea and Japan were analyzed and compared. Results: South Korea follows a centralized approach to EMS, whereas Japan operates with autonomous bodies that establish their own criteria. Japan considers more regional variables than South Korea. In South Korea, there are shortages in fire station deployment among the 119 emergency medical resources in certain regions, leading to significant regional disparities. South Korea has a larger population served by its 119 emergency medical resources with a higher workload and dispatch numbers than Japan. The percentage of non-transported patients among the total number of dispatches was higher in South Korea. Conclusion: Increasing the number of medical professionals and ambulances per population to the level of Japan to reflect local conditions and include various underlying variables such as daytime population, aging, and emergency dispatch conditions in the deployment of 119 emergency resources, and to reduce the deployment gap between regions, will contribute to improving the performance of the South Korea EMS system.

This research was conducted to improve the image of female emergency workers in a fire service organization by studying the perception trends of the increasing number of female paramedics. This human resource can be utilized more effectively by using the study results as baseline data. We conducted a survey from May 1 to June 30, 2013. The survey was analyzed using Q methodology and the program QUANL. For the Q sample, 31 emergency rescue paramedic students who had experienced ambulance field education were selected. As a result, four types of female paramedics were found; "superwoman," "hero" (who pushes against limits of stamina), "delicate guardian angel," and "skillful desk worker." The explanation powers were as follows: type I: 42.2%; type II: 4.8%; type III: 4%; and type IV: 3.6%. The sum of the figures explained 54.7% of the total variables. Generally, the students recognized female paramedics as professionals, but physical strength, baby care, and caring were considered as burdens. This requires changes in the organization's perception of female paramedics and an institutional strategy.

Now many sustitution and false articles is used in korea instead of heshouwu. To use heshouwu correctly, we will make a quilitative certificational plan of heshouwu to investigate all of lieraturea, records and documents. And we could reach conclusions as folloews. 1) Source of plant Heshouwu is a root tuber of a perennial herb Polygonum multiflorum Thunberg(Family : Polygonaceae). 2) Harvest After planting 3-5 yaers, harvesting in an autumn, washin clean the mud, a big heshouwu cut off a half or section, dry in sunny place or at a little fire. When harvesting, we harvest only a big thing, a small thing transfer a field, after culturing of 1-2 years, harvest at big roots. Harvesting is done usually in an autumn after 3 years. When collecting a seed, we must harvest a heshouwu the next year. 3) Process We must process heshouwu at the decoction of black beans, heshouwu suck in the decoction of black beans, heat with steam in an iron pot. Black beans is used every 100 kg of heshouwu. 4) Quility (1) Funstional standards It is good that weight is heavy and outer skin is yellow-brown, section surface is light red color, powdery and has a figure such as clouds in section. (2) Physicochemical standards Heshouwu expesses a various chang of components in process of working. We think that it need to add a standard of detection about 2,3,5,4'-tetrahrdroxystilbene-2-O-${\beta}$ -D-glucoside in a current authentic document which is a water-soluble component of heshouwu. It must that Dry on loss is less than 14.0%, content of ash is less than 5.0%, Content of acid-nonsoluble ash is less than 1.5%, Content of extract is more than 17.0%. A fixed quantity of 2,3,5,4'-tetrahrdroxystilbene-2-O-${\beta}$ -D-glucoside is more than 1.0%. Contens of heavy metal has to detect less than 30 ppm and there is no reminding agriculural medince.

Purpose : The purpose of this study was to provide an appropriated direction for fire service organizational management by analyzing the violence experiences and turnover intention of female 119 emergency medical technicians (119 EMT) in Korea. Methods : The questionaries were obtained from 415 female 119 EMT in Korea from April 27 to March 8 in 2009. The collected data were analyzed with SPSS WIN 19.0 program. Results : Female 119 EMTs experienced 94.9%-verbal insults, 57.1%-violence aggression, 62.89%- potential violence, 32.5%-physical assault. About 76.4% of the subjects experienced to feel shame about the verbal insults. They had a stress level (mean 5.47 out of 10) and about 41.2% was more than seven points. About 39.3% of the subjects responded turnover intention. Conclusion : We proposed the preventive program against violence as well as critical incident stress debriefing. These results are expected to be useful in making human resource management plans to lower turnover intention.

Synchronous wind-induced pressures, measured in wind-tunnel tests on model buildings instrumented with hundreds of pressure taps, are an invaluable resource for designing safe buildings efficiently. They enable a much more detailed, accurate representation of the forces and moments that drive engineering design than conventional tables and graphs do. However, the very large volumes of data that such tests typically generate pose a challenge to their widespread use in practice. This paper explains how a wavelet representation for the time series of pressure measurements acquired at each tap can be used to compress the data drastically while preserving those features that are most influential for design, and also how it enables incremental data transmission, adaptable to the accuracy needs of each particular application. The loss incurred in such compression is tunable and known. Compression rates as high as 90% induce distortions that are statistically indistinguishable from the intrinsic variability of wind-tunnel testing, which we gauge based on an unusually large collection of replicated tests done under the same wind-tunnel conditions.

Concurrent competition for finite resources by multiple parts in flexible manufacturing systems(FMS's) and inappropriate initial marking or net structure of Petri net with share resources results in deadlock. This is an important issue to be addressed in the operation of the systems. Deadlock is a system state so that some working processes can never be finished. Deadlock situation is due to a wrong resource allocation policy. In fact, behind a deadlock problem there is a circular wait situation for a set of resources. Deadlock can disable an entire system and make automated operation impossible. Particularly, an unmanned system cannot recover from such a status and a set of jobs waits indefinitely for never-to-be-released resources. In this paper, we proposed a deadlock prevention method using siphon and trap of Petri net. It is based on potential deadlock which are siphon that eventually became empty. This method prevents the deadlock by the control of transition fire and initial marking in the Petri net. An given example of FMS is shown to illustrate our results with deadlock-free.

Recently, researchers have become interested in natural ester fluids, as they are an environmentally friendly alternative to mineral oils. Natural ester fluids are a natural resource made from plants; they have higher biodegradability, flash, and fire points, and a greater permittivity compared to conventional mineral oils. However, natural ester fluids also have a higher pour point, viscosity, and water content. These characteristics can hamper circulation and impair the electrical properties of an oil-filled transformer. A large amount of data has been accumulated over the years in regards to mineral insulating oil involving dielectric breakdown voltage and lightning impulse tests. However, natural ester fluids have not had their electrical properties sufficiently characterized. In this paper, we present an investigation into the characteristics of the electrical discharge development in natural ester fluids and in an oil-filled transformer near the pour points. The experiment results show that the electrical properties decreased according to a decrease in the ambient temperature and freezing time. It was found that the pour point and water content of natural ester fluids have a significant effect on the electrical properties.

It was a method of weed removing, called as whagyeongsoonoobeob. Namely, the Hwanoobeob was the weeding method came from "Jeminyosool" in old China, and had been descended to "Wibinmyeongnonggi", "Nonggajibseong" and "Gwanongsocho" in the $16\sim18^{th}$ century of our country. The method was applied to rice paddy after applying direct-seeding, burning by unit before watering to remove weeds and to save rice plants. It would be applied with a method of using non-selective herbicide such as paraquat and oxyfluorfen, or radiation treatment, as a simple and safe weed removing method.
