This study analyzed concentration and characteristics of hazardous substances in treatment of leachate from carcass burial areas by using high temperature thermal desorption (HTTD). Concentrations of pollutants emitted from HTTD treatment of leachate contaminated soil of carcass burial sites satisfied the emission standards for 11 pollutants from domestic waste incineration facilities. Dioxin concentration was 0.0060 ng I-TEQ/Sm3 and 0.0061 (0.0055-0.0070) ng ITEQ/ Sm3 in the normal operation condition and the experimental condition, respectively, which are much lower than the MSWI Standard of 0.1ng I-TEQ/Sm3. As a result, it was considered that leachate from carcass burial areas could be treated by high temperature thermal desorption (HTTD).

Since 2010, RDA has discovered 30 Green-Road as the way of developing rural area. However, results from conference with expert and village leaders of Green-Road concluded that there were problems such as little financial benefits due to mismanagement and needs of improving the efficiency of management. In order to respond to these issues, this research has conducted empirical investigation about the status, management of Green-Road and its influences on local area. Main purposes of this investigation was to reveal the various obstacles in road management, and to find better ways of road management. To accomplish the goal of research, this study conducted survey and interviews with leaders in villages. Particularly, the investigation had focused on the specific management issues suggested by village leaders. Based on the results, this research suggested establishing a committee for creating leaders network and developing effective management method in order to improve road management and its consequences.

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.

In rural areas, in spite of the development projects of town and houses has been performed after the New Community Movement, due to rapid industrialization and urbanization, which lasted until the 2000s from the 1980s, out-migration to the cities, changes in the industrial structure, rapid aging was carried. As a result, the gap of housing environment between urban and rural areas became more serious. The meantime, the housing problem is recognized only to the problems of the big cities, mostly urban public housing policy oriented. However, when you check the indicator of the housing environment, such as the percentage of aging housing, rural environment has become a relatively poor compared to the city. In addition, due to a decrease in income and aging of the population living in rural areas of existing infrastructure to improve the living environment is weakened. And inside of the rural areas, changes in the housing environment and polarization phenomenon is becoming increasingly serious. Therefore, in this study, there is a purpose to be presented the improvement direction for efficient implementation of house remodeling support program for underprivileged group in rural areas and requires immediate attention improvement of housing environment. Previously, House remodeling support project in rural areas was carried out at the initiative of local governments and government mainly. For this reason, it is difficult due to limited institutional, to reflect the necessary parts directly to the real life of the residents. And, the demand for improvement of housing environment need modifications to solve the inconvenience of life of residents directly in many cases. It is considered that community-based house remodeling support project is to be carried out through the participation of local residents.

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.

This study describes the identification of Panax species using mitochondrial consensus primers. Initially, a total of thirty primers were tested in ten Korean ginseng cultivars and two foreign Panax species, P. quinquefolius and P. notoginseng. In the polymerase chain reaction (PCR) amplification results, three primers (cox1, nad1/2-3 and nad2/1-2) generated co-dominant polymorphic banding patterns discriminating Korean ginseng cultivars from P. quinquefolius and P. notoginseng. However, these primers could not generated polymorphisms among the Korean ginseng cultivars, and simply represented species-specific polymorphisms for P. quinquefolius and P. notoginseng. Primers PQ91 and PN418 were designed from the consensus sequence of nad1/2-3 region. Two banding patterns (A or B) were detected in PQ91. Korean ginseng cultivars and P. notoginseng shared the same banding pattern (A type) and P. quinquefolius was identified another banding pattern (B type). In the case of PN418, two banding patterns (A or B) were detected in the Korean ginseng cultivars and two foreign Panax species. Korean ginseng cultivars and P. quinquefolius shared the same banding pattern (A type) and P. notoginseng was identified another banding pattern (B type). The combination banding patterns of three Panax species, Korean ginseng cultivars (Panax ginseng C. A. Mey.), P. quinquefolius and P. notoginseng, was identified as 'AA', 'BA' and 'AB', respectively. Consequently, PQ91 and PN418 primer sets can be used to distinguish among Panax species.

In recent years, the number of walking-tourists who visit Jeju olle trail are increasing every year and the ripple effect is a rapid change on the roles and leadership of local people in rural villages. The reason for the change is that most Jeju Olle Trails cuts through the rural village in Jeju island. However, most of travelers just walked along the trails, no one was interested about villages along the Olle roads. For these reasons, many rural villages would not get any benefits such as non-farm income, sales profit and also can not activate the facility of village and infrastructure. Therefore, we study on Revitalization Method for rural villages through the Analysis of characteristics of tourist in Jeju Olle Trails and a field survey research too. In this process, we investigated the status and characteristics of the rural villages of Jeju island in the first step. Then, we considered the distinct characteristics and factors for improving of the 10 places with site investigation where were recommended by Jeju Olle Corporation and Jeju Agricultural Technology Center in second step. Lastly, we arranged the resident's requirement and result of survey and interview with leaders of rural village. As a result, we suggest the activation methods for residents and leaders of rural area and this study is also expected to help management of rural villages and also is an important study to improve importance of utilizing of more people visiting in Jeju Olle Trails.

This study was carried out to identify Korean ginseng cultivars using peptide nucleic acid (PNA) microarray. Sixty-seven probes were designed based on nucleotide variation to distinguish Korean ginseng cultivars of Panax ginseng. Among those PNA probes, three (PGB74, PGB110 and PGB130) have been developed to distinguish five Korean ginseng cultivars. Five Korean ginseng cultivars were denoted as barcode numbers depending on their fluorescent signal patterns of each cultivar using three probe sets in the PNA microarray. Five Korean ginseng cultivars, Chunpoong, Yunpoong, Gopoong, Gumpoong and Sunpoong, were simply denoted as '111', '222', '211', '221' and '122', respectively. This is the first report of PNA microarray which provided an objective and reliable method for the authentication of Korean ginseng cultivars. Also, the PNA microarray will be useful for management system and pure guarantee in ginseng seed.
