An Intergenerational Horticultural Program in a rural community in Korea was tried out to enhance social interaction between elderly citizens and children, to promote the positive self-esteem of the elderly in a rural community, to change the attitude of children towards the elderly, and to create a rural community full of vitality. The clients were 20 elderly (60-80 years old) and 40 preschool children (6-7 years old). The activities in this program included seed of hope, round autumn garden, dish garden, in the vegetable patch, flower decoration for the Chuseok Festival, rainbow flower basket, heart card, fragrance of love, and a kimchi party. The results were a decrease in depression among the elderly from 44.0% to 33.7%. General satisfaction among the elderly was 100%. The desire to rejoin among the elderly was 100%. General satisfaction among the children was 100%. The desire to rejoin among the children was 93.5%.

This study was performed to analyze the improvement of soil physical property and soil biota characteristics through cultivation of green manure crops for a one-year period before creation of a tea plantation as follows. The study revealed that the contents of available phosphate tended to decrease after sod-culture by green manure cultivation and open-pollination, when compared to the level before cultivation. The ratio soil porosity increased by approximately 30% when Crotalaria juncea and Sorghum bicolar L. Moench were cultivated, while the soil bacteria and fungi also increased. In a research on microfauna using a pit fall trap, the population number of the microfauna was 174 of 27 species in the plot of open-pollinated sod-culture and no organic matter application, and 268 of 26 species in the plot of Sorghum bicolar L. Moench. Consequently, the culturing tool of Crotalaria juncea recorded the highest level of species diversity at 2.5, the evenness index at 3.7 and richness at 4.6, with the lowest level of a dominance index. The ecological quotient of microfauna was 0.76 in the plot of Sorghum bicolar L. Moench, and 0.63 in the plot of Crotalaria juncea.

KNU corn breeding team in collaboration with International Corn Foundation (ICF) is dedicated to develop super corn hybrids for developing countries like Nepal and Cambodia. The team works to develop high bio-energy maize hybrids for Korea. Crossing of temperate with tropical germplasm shows new heterotic patterns. Four tropical inbred lines from IITA, Nigeria, ten sub-tropical lines from Nepal and two temperate lines (P45 and 69B) from Korea were crossed to produce single-cross hybrids. Besides, four single-cross hybrids from Nepalwere crossed with P45 and 69B to produce three-way crosses. Gray leaf spot (Cercospora zea-maydis) being the most important problem of corn in mid-hills of Nepal, GLS resistant materials from IITA were crossed with Nepal materials in Cambodia to produce GLS tolerant hybrids. Single-cross hybrids were evaluated at ICF Agriculture Center in Cambodia and KNU farm, Gunwi in Korea in 2008. The three-way crosses were planted at Gunwi farm and the GLS resistant materials were planted at Khumaltar station of Nepal Agricultural Research Council, Kathmandu. Crosses of Tzi-25 with RML-4 and RL-111 and RL-105xNML-2 were found outstanding in Cambodia. Four tropical x subtropical hybrids (Tzi-18xRML-4, Tzi-18xRL-14, Tzi-25xRL-14 and RL-47xTzi-25), four temperate x subtropical hybrids (P45xRL-111, P45xRML-8, RML-5x69B and 69BxRL-105). P45xGaurab was the most suitable for both grain and biomass production.

Offspring have been produced from somatic cells in a number of species. This biotechnology introduced a new phenomenon in reprogramming and differentiation of somatic cell, namely totipotency. However, birth of oversized calves and perinatal abnormalities such as increased gestation length, lack of spontaneous parturition, higher incidence of dystocia, and reduced perinatal viability of offspring are frequently observed in pregnancies of cloned bovine fetuses. Disturbance of feto-placenta has been proposed as likely causes for abnomal growth. However. Little is known the mechanism responsible for the perinatal problems. Therefore, we focused on gestation length in somatic cell nuclear recipient cows. To solve this issues, placental tissues of control and cloned bovine were obtained by a cesarean section (C-section) before 5 days of paturition. Total RNA from control and cloned bovine placenta was extractd by TRIzol reagent. GeneFishing DEG kits (Seegene) were used to identify differentially expression genes. Total RNA (3 ug) were synthesized by M-MLV reverse transcriptase (200 u/ul) with 10 uM dT-annealing control primer (ACP1) at 42C for 90 min. Then, first-strand cDNA (50 ng) was amplified using the 5 uM arbitary ACP (1-20) and 10 uM dT-ACP2 primers. Some specific expression genes were amplified, Now, we are cloning and sequencing. These finding strongly can be support to solve the problems for parturition delay in nuclear transfer cows, suggest that placenta specific proteins are key indicators for the aberration of gestation and placental function in cows.
