The purpose of this study is to identify the determinants of local farmers' participation and acceptance level in traditional agricultural technology conservation activities, using on the traditional agricultural water utilization system in Uiseong designated as Korea's important agricultural heritage system No. 10. The Heckman sample selection model was used to solve the selection bias. The results show that as the interest in the conservation of the agricultural ecological and environment is high, as the traditional agricultural system in Uiseong is used, as the cultivation area of paddy field increased, and as the age 50s or older, the willingness to participate in conservation activities increased. The results also indicate that as the experience of participating in the conservation of the agricultural ecological and environment and the hours of education are increased, the knowledge of the traditional agricultural system in Uiseong is low, and as the cultivation area of paddy field decreased, the acceptance time for conservation activities increased. The results of this study may contribute to government's policy for traditional agricultural technology conservation.

Traditional agriculture technology is absolutely valuable not only to preserve biological diversity but construct an eco-friendly agricultural system. As the awareness of food safety has been growing, traditional technologies in the past agriculture literatures have obtained more attention sine chemical or synthesized fertilizer and agricultural pesticide were not used in these traditional agriculture ways. This study aims to evaluate development values on six kinds of agriculture literatures published before initial 1970s using Delphi technique and Correspondence analysis. The domains of assesment are include livestock sanitation, breeding management, feeding program and an extra part which 261 traditional agriculture technologies were first extracted from. From these technologies, livestock experts deducted 228 items and selected items more than 3.0 from all three areas including usefulness, scientific characteristic and economical efficiency utilizing Delphi technique.: 35 items from usefulness, 31 items from scientific characteristic, and 18 items from economical efficiency. The 23 technology items were finalized after adding five modern feasibility items recommended by experts to 18 items gaining more than 3.0 in at least three areas. The agriculture technologies were categorized into four areas where were analyzed using Correspondence analysis. The results revealed that 'sustainable farming technology', 'scientific character verification', ' modernized technology development', and 'intellectual property right' were placed closely one another except 'economy efficiency'. The result implicated that scientific verification and economy efficiency should be considered in order to sustain traditional agriculture technology into a modernized way and to protect intellectual property right of these technologies.

The aim of this study was to elucidate the changes in the microbial community and biochemical properties of a traditional sweet paste during fermentation. PCR-denaturing gradient gel electrophoresis (DGGE) analysis showed that Aspergillus oryzae was the predominant species in the koji (the fungal mixture), and the majority of the fungi isolated belonged to two Zygosaccharomyces species in the mash. The bacterial DGGE profiles revealed the presence of Bacillus subtilis during fermentation, and Lactobacillus acidipiscis, Lactobacillus pubuzihii, Lactobacillus sp., Staphylococcus kloosi, and several uncultured bacteria were also detected in the mash after 14 days of main fermentation. Additionally, during main fermentation, amino-type nitrogen and total acid increased gradually to a maximum of $6.77{\pm}0.25g/kg$ and $19.10{\pm}0.58g/kg$ (30 days) respectively, and the concentration of reducing sugar increased to $337.41{\pm}3.99g/kg$ (7 days). The 180-day fermented sweet paste contained $261.46{\pm}19.49g/kg$ reducing sugar and its pH value remained at around 4.65. This study has used the PCR-DGGE technique to demonstrate the microbial community (including bacteria and fungi) in sweet paste and provides useful information (biochemical properties) about the assessment of the quality of sweet paste throughout fermentation.

This study tried to analyze the learning effectiveness of multi-media based class by comparing with traditional classroom method. The "Basic Agricultural Technology" course that is one of the required courses of agricultural high school was selected and its contents were digitalized on MS Powerpoint for multi-media based class. The thirty students were sampled for each experimental and control groups. The homogeneity and learning achievement of sample groups were tested for experiment. Same teacher took the classes of two groups and delivered same contents of course. Only difference between two groups was the delivery method, one is traditional classroom teaching method and the other was the multi-media based class. The learning achievements and satisfaction of sample were post-tested in order to analyze the learning effectiveness by comparing two teaching methods. The results showed that there was a significant difference between experimental and control group in learning achievement after ANCOVA controlled pre-test as covariance(F=5.08, p<.05). It means that the learning achievement of multi-media based class was higher than that of traditional classroom group. The results also showed that a significant difference in students’ satisfaction between two groups (t=5.57, p<.001). This study concluded that using multi-media in class could produce more learning achievements and satisfaction of students than traditional classroom method.

New Korean traditional wine was developed using Gugija (Lycii fructus) and medicinal plants. Gugija wines were brewed by serial addition of Gugija root and medicinal plants into rice mash containing 1% Gugija fruit, and its physioco-chemical properties, physiological functionality, and overall acceptability were investigated. Traditional Gugija wine prepared by serial addition of 0,1% each Gugija roots and Doochung, and 1.0% each Gamcho and dandelion into the rice mash containing 1% Gugija fruit showed highest acceptability and ethanol content (16,0%). Traditional Gugija wine prepared by adding 0.1% Gugija leaf into the Gugija wine showed highest acceptability and high antihypertensive angiotensin I-converting enzyme inhibitory activity (66.1%).

Antitumor activities of a peptide fraction isolated from traditional Korean soy sauce (SSP) were investigated in vitro and in vivo using cancer cell lines and F9 teratocarcinoma-bearing BALB/c mice. SSP exerted a dose-dependent antiproliferative effect on P388D1 mouse lymphoma, F9 mouse teratocarcinoma, and DLD-l human colon cancer cells with $IC_{50}$ values of 11, 50, and $50\mug/ml$, respectively. Tumor growth in F9 teratocarcinoma-bearing BALB/c mice, orally administered with 80 and 200 mg/kg/day of SSPs, was inhibited 10.3% and 52.4%, respectively, and survival days increased by 11.9% and 22.1%, respectively, compared to the control group. The results of antitumor activities exerted by SSP in vitro and in vivo suggest the feasibility of using SSP as an antitumor agent.

This study had done to find an easily-dyeing method for novices because the dyeing method of traditional indigo has not been general to the public so that only an expert could dye the fibers. The results are as the following. When the powders after burning the shell of cockle (tegillarca granosa) were added. pH of the solution was 12.35 The k/s value of 2.49 was the highest in the dye after dipping in the solution of indigo for 1-2 days and the k/s value was 3.10 when adding 20 g/l of the starch (55% corn-starchy products in Korean market) into the solution of indigo. In addtion, the k/s value was the highest when fermenting temperature was $30^{\circ}C$ and when the powders after burning the cockle shell were 4 g/l. There were no differences between water and lye of rice straw which had used for the ferment of indigo. The components of two dye which has traditionally made of the cockle shell and which has made of calcium hydroxide were all the same.

Beekeeping has been practiced for centuries in Ethiopia. Currently, there are three broad classification of honey production systems in Ethiopia; these are traditional (forest and backyard), transitional(intermediate) and modern(frame beehive) systems. Ethiopian honey production is characterized by the widespread use of traditional technology resulting in relatively low honey yield and poor honey quality. Despite the challenges and constraints, Ethiopia has the largest bee population in Africa with over 10 million bee colonies, of which 5 to 7.5million are hived while the remaining exists in the wild. Consequently, these figures, indeed, has put Ethiopia as the leading honey and beeswax producer in Africa. In fact, Ethiopia has even bigger potential than the current honey production due to the availability of plenty apicultural resources such as natural forests with adequate apiculture flora, water resources and a high number of existing bee colonies. However, lack of well-trained man powers, lack of standardization, problems associated with honey bee pests and diseases, high price and limited availability of modern beekeeping equipment's for beekeepers and absconding and migration of bee colonies are some of the major constraints reported for beekeeping in Ethiopia. In this review, an attempt was made to present all beekeeping practices in Ethiopia. The opportunities and major constraints of the sector were also discussed.
