A new gerbera cultivar 'Paspin' was released by the National Institute of Horticultural & Herbal Science (NIHHS) in 2009. A cross was made between 'Lilabella' and 'Mephisto' with purple and semi-double in 2005. After investigation of the characteristics for five years (from 2005 to 2009), it was selected specially as a cut flower. The 'Paspin' cultivar has a pastel pink flower color (RHS R52B) with green disc center and semi-double flower. It has large-sized flowers which average flower diameter is about 12.8 cm. And inner ray floret and disc diameters are 7.87 cm and 2.57 cm, respectively. It has an adequate peduncle height of 48.6 cm, and a longer vase life of 10.8 days. It is vigorous in growth and also adaptable to the local cultural environments of Korea. It is expected that if the 'Paspin' cultivar will be planted, the royalty fees to be paid to other countries can be saved. And the local growers will also be benefitted since the cost of cultivars will be lower than the imported ones.

Wireless smart sensor networks (WSSNs) have been proposed by a number of researchers to evaluate the current condition of civil infrastructure, offering improved understanding of dynamic response through dense instrumentation. As focus moves from laboratory testing to full-scale implementation, the need for multi-hop communication to address issues associated with the large size of civil infrastructure and their limited radio power has become apparent. Multi-hop communication protocols allow sensors to cooperate to reliably deliver data between nodes outside of direct communication range. However, application specific requirements, such as high sampling rates, vast amounts of data to be collected, precise internodal synchronization, and reliable communication, are quite challenging to achieve with generic multi-hop communication protocols. This paper proposes two complementary reliable multi-hop communication solutions for monitoring of civil infrastructure. In the first approach, termed herein General Purpose Multi-hop (GPMH), the wide variety of communication patterns involved in structural health monitoring, particularly in decentralized implementations, are acknowledged to develop a flexible and adaptable any-to-any communication protocol. In the second approach, termed herein Single-Sink Multi-hop (SSMH), an efficient many-to-one protocol utilizing all available RF channels is designed to minimize the time required to collect the large amounts of data generated by dense arrays of sensor nodes. Both protocols adopt the Ad-hoc On-demand Distance Vector (AODV) routing protocol, which provides any-to-any routing and multi-cast capability, and supports a broad range of communication patterns. The proposed implementations refine the routing metric by considering the stability of links, exclude functionality unnecessary in mostly-static WSSNs, and integrate a reliable communication layer with the AODV protocol. These customizations have resulted in robust realizations of multi-hop reliable communication that meet the demands of structural health monitoring.

We bred a mulberry cultivar named Sangmaru, through local adaptability test, which is under registration as a new cultivar for fruit production. Local adaptability test had been carried out at three places (Suwon, Cheongju, and Jangseong) for seven years from 2008. This is tetraploidy variety belonging to Morus alba L. made by colchicine treatment on growing point of 'Chungil (Morus alba L.)' winter buds. Sangmaru was high yielding cultivar in fruit productivity by 6% compared to control cultivar 'Chungil (Morus alba L.)' for five years. Although Sangmaru was similar in sugar content of mulberry fruits, it was bigger than that of 'Chungil'. It is adaptable to every where except the places where cold damage and sclerotic disease happen frequently.

We bred a mulberry cultivar named Sangberry, through local adaptability test, which is under registration as a new cultivar for fruit production. Local adaptability test had been carried out at four places(Suwon, Kongju, Jangseong and Sangju) for six years from 2005. This is tetraploidy variety belonging to(Morus alba L.) made by colchicine treatment on growing point of winter buds. Sangberry was high yielding cultivar in fruit productivity by 70% compared to control cultivar "Chungilppong(Morus alba L.)" for four years. Although Sangberry was a little lower in sugar content of mulberry fruits, it contains more bioactive materials like C3G, rutin and amino acids than Chungilppong. It is adaptable to every where except the places where cold damage and sclerotic disease happen frequently.

In the present study, the characteristics and changes in the vegetation of Mt. Cheongryang, Inchon, were examined to identify and determine appropriate ways to restore the health of the urban forest and to preserve its vegetation. The vegetation of the community of Quercus mongolica (Mongolian oak) on Mt. Cheongryang appeared to decrease in response to the control of the wilt disease of oak trees. The communities of Sorbus alnifolia (Korean mountain ash) and Styrax japonicus (Snowbell tree) have increased. Pinus rigida (Pitch Pine) had its overall territory decrease, but the current state of the Pinus rigida (Pitch Pine) was estimated to be stable due to its dominance as a tree layer species. In regards to Robinia pseudoacacia (Black Locust), the urbanized species of Sorbus alnifolia (Korean mountain ash), and Styrax japonicus (Snowbell tree), their areas have increased with the appearance of Magnolia obovate (Whiteleaf Japanese Magnolia). The biodiversity of Mt. Cheongryang has decreased by simplifying species in the tree layer and understory species thereof, and the initial success of species in marginal areas has increased. The absence of potential succession was attributed to the termination of ecological succession; thereby, the current vegetation structure was concluded to be remaining as it is for the time being. Soil texture in the mountain primarily consisted of sandy loam or loamy sand; the pH of the soil was in the range 4.26-4.86, rendering a mean pH of 4.59. The content of organic matter (O.M.) appeared having a distributing range of 2.18-9.60%, rendering a mean value of 4.33%. To promote species diversity, several methods are suggested, such as prevention of soil acidification, selecting nationally-grown trees from moist soil or valleys for afforestation, preventing species appearing due to urbanization or excessive growth, protecting the understory vegetation and species with hygropreference, and managing the forest to maintain a multi-layered vegetation structure.

'Goamibyeo', a mid-late maturing ecotype with high amylose content in kernels, was developed by the rice breeding team of National Yeongnam Agricultural Experiment Station(NYAES) in 2000 and released in 2001. This variety was derived from the three way cross of Milyang 95//Kimcheonaengmi/$2^*Ilpumbyeo$ (in 1992 summer) through the pedigree breeding method and designated as 'Milyang 168' in 1997. The heading date of 'Goamibyeo' was Aug. 18 in ordinary season with culm length of 85 cm. However, 'Goamibyeo' showed susceptible to bacterial leaf blight, stripe virus and leaf blast disease. The amylose content of 'Goamibyeo' in milled rice kernels is about 26.7% with translucent and clear in chalkness. Thus, 'Goamibyeo' is expected to be used as a source grain for rice noodle industries. The milled rice yield potential of 'Goamibyeo' is about 5.38 MT/ha in local adaptability test of three years and it would be adaptable to Yeongnam plain of Korea.

Recently, peoples are greatly concerned with global temperature change because global warming can be a potential serious effect on agriculture production such as yield reduction and poor grain quality. On the other hand, it can bring some beneficial effects through twice cultivation of rice in temperate region. In order to overcome this situation, we developed extremely early-maturing rice 'Milyang255' which heading date was similar with 'Jinbuolbyeo'. Based on agronomic characteristics of 'Milyang255', it has very short stature as 65 cm of culm length and slightly lower spikelets number per panicle compared with that of 'Jinbuolbyeo'. However, the grain appearance, palatability and other items were better than those of 'Jinbuolbyeo' in panel test of cooked rice. The milled rice yield of 'Milyang255' is 3.94 MT/ha at the early transplanting. Especially, its grain filling rate was higher and faster than Jinbuolbyeo and the head rice ratio in milled rice was also higher. Thus, 'Milyang255' can efficiently reduce the growth duration of rice cultivation and also be useful material for research on twice cultivation of rice in Korea.
