이 연구는 일반적인 인지이론을 조종사 기술의 범위로 확대시켜, 조종사가 얼마나 빠르고 정확하게 상황인식을 하는지를 제시문과 비행 장면 일치성 측정을 통해 알아보았다. 이 연구의 목적은 두 가지 측면의 변인에 따라 상황인식이 전문성의 영향을 받는지를 알아보는 것이다. 비행 요소간의 관계를 나타내는 비행 상황 변인들과 비행 요소의 내용을 나타내는 비행 상황 변인들 모두 비행 상황인식에 영향을 주었다 그리고 작업기억은 다양한 정보들을 통합시키는 데 결정적인 역할을 하는 것으로 나타났다. 이러한 결과는 비행 상황인식의 바탕인 인지적 과정을 나타내는 구조화통합 모델의 이론적 틀 안에서 설명되어진다.

Establishment of emission concentrations of PCDDs and PCDFs in emission gases from 85 domestic crematories were measured. The relationship between PCDDs/DFs and several factors such as structure, equipment and operational state of the crematory is discussed. Furthermore, emission of PCDDs/DFs from all crematories in korea is estimated. The following results are obtained: (1) total concentration (2,3,7,8- substituted isomers) of PCDDs/DFs was 0.113 ~ 14.34 ng/ Sm3, whose TEQ concentration was 1.815 ng-TEQ/Sm3; (2) total emission of PCDDs/DFs from crematories in korea was estimated to be 1.815 g-TEQ/yr.

Infectious diseases in domestic animals of carcase were increasing every year. According to the monthly report for infectious disease from Ministry for Food, Agriculture, Forestry and Fisheries, 11,954 heads of cattle, 518,178 heads of pig, 232,850,244 heads of bird were reported in 2011. Infectious diseases of carcase almost spread on a national scale. Dead or emergency preventive carcase are completely treated on bury. Since the treatment of carcase on bury are generating soil, underground water and source water pollution, introduction of new preventive system should be considered. In this study, literature survey and case studies to prevent the spreading of virus for infectious disease and second environmental pollution were investigated. The actual experiments using the existing incineration facilities were also performed to ensure the possibilities of safe treatment of carcase. On the other hand, the moving-type incineration are also being developed and its operation manual will be prepared. Among the investigated incinerators, stoker type incinerator was not suitable for the treatment of carcase, however, other incinerators such as fluidized-bed type incinerator, rotary kiln type incinerator ware shown to be suitable. But even for the stoker type incinerator, if the pre-treatment facilities( grinding, crushing) are installed, it will also be a suitable method. The analytical results for air pollutants(including dioxin) emitted from the final exit were all satisfied to the air pollution emission standards.

In this study, PCDDs/DFs concentrations in flue gases from 58 crematories and in fly ashes and bottom ashes (mainly bone) from several crematories were measured to grasp the present state of PCDDs/DFs emissions from crematories. The effects of several factors were discussed to prevent PCDDs/DFs emissions from crematories. Total concentration of PCDDs/DFs was ranged from 0.113 to 87.461 ng/Sm3 and toxic equivalent concentration was ranged from 0.019 to 15.347 ng-TEQ/Sm3. As the results obtained in this research, the following measures to reduce PCDDs/DFs emission are recommended for existing crematories: (1) keeping the temperature at < 800oC or < 850oC in main/secondary chambers during a whole cremation, (2) lowering the temperature in the dust collector, (3) installing the high efficiency dust collector and reducing dust concentration to less than 0.02 g/Sm3, and (4) installing the sampling point for monitoring of PCDDs/DFs.

The present study is designed to know the effect of cultivative environment and conditions, locational genetic variation on the content and components of seed isoflavones soybean genotype. The concentration of isoflavones showed difference between three different seeding time. Specially, Somyung of normal seeding (6. 21) revealed the highest concentrations (7657.0 ㎍ g-1) than other soybean seeds. On the other hand, Cheongjakong and Taekwangkong of early seeding (5. 25) showed the lower concentrations (1518.6 ㎍ g-1, 2524.0 ㎍ g-1) than other soybeans. For different regions, Taekwangkong of Yeoju region had the highest total isoflavone concentrations (3227.5㎍ g-1) than other cultivation regions. While, Taekwangkong of Miryang region (619.5 ㎍ g-1) revealed lower concentrations than other regions. And, Cheongjakong of Yeoju regions also revealed higher concentrations (3140.1 ㎍ g-1) than other regions. On the other hand, Cheongjakong of Miryang (1619.4 ㎍ g-1) showed lower concentrations of total isoflavone concentrations. In our present study, the isoflavone concentration of soybean was influenced by seeding and cultivation regions.
