The simple sequence repeat (SSR) system is generally regarded as one of the most practical marker systems for the genotyping and variety description of diverse crops. This study was conducted in order to develop Oriental melon-derived SSR markers which could be utilized in the detection of polymorphisms for a variety of commercial C. melo lines. ‘Gganchi’, a Korean landrace, was employed as a basic material for development. For the isolation of SSR clones, 5′ anchored PCR utilizing the degenerate primer, PCT4, and a semi-genomic library construction accommodating the microsatellite-rich PCR profiles were employed. The sequence information was obtained from the primary SSR clones, and gene-specific primers (GSP1) were developed for terminal microsatellites harboring more than eight repeat units. A chromosome-walking procedure was followed in an effort to develop another gene-specific primer (GSP3) on the opposite side of the target microsatellites. Eventually, both locus-specific primers were constructed for the 16 contiged SSR clones. Among these, the unique polymorphism was observed in 7 of the primer sets. The observation of polymorphisms was extended to 44 C. melo accessions, including both types of Oriental melon and western cultivars, thereby indicating the specificity of the developed primer sets at the given SSR loci, as well as the general utility of the markers for the genetic evaluation of a variety of melon accession types.

슬러리발포 및 겔캐스팅법을 이용하여 세라믹 다공체를 제조하였다. 또한, 이를 분진제거용 여과재로 응용하기 위해 기공구조 및 공기 투과율에 관한 연구를 실시하였다. 기공률은 80% 정도이며, 100㎛와 200㎛, 두 종류의 기공크기를 갖는 다공체를 제조하였다. 기공들은 창(window)을 통해 연결된 연속성 기공구조를 갖는다. 미세분진을 제거하기 위해, 다공체의 한쪽 면은 표면여과층을 형성하였으며, 기공크기는 10 ㎛이하이다. 기공크기가 200㎛인 다공성지지체의 경우, 900∼1000×10-13 ㎥의 투과율은 나타내었으며,기공크기가 100㎛인 지지체의 투과율은 600∼700 × 10-13 ㎥로 각각 측정되었다. 표면여과층이 형성된 여과재의 투과율은 약 200 × 10-13 ㎥로서 지지체의 기공크기에 관계없이 거의 일정한 값을 나타냈다. 또한, Flyash 분진을 이용하여 측정한 여과재의 집진효율은 99.9% 이상인 것으로 나타났다. This study was carried out to evaluate the pore structure and air permeability of the foam ceramic filter prepared by using foam method. Two different types of agents, Benzethonium chloride(C27H42NO2Cl) and Sodium Lauryl Sulfate(CH3(CH2)11OSO3Na) were used for foaming slurry. Porosity of foam ceramics was about 80 % and pore sizes were differed as 200 and 100 ㎛ respectively according to types of agents. It was observed that foam ceramics had continuous pore structure that pores were connected each other by small pathways called windows. For collecting dust, one side of foam ceramic support was coated with fine particles that the size was 20∼50 ㎛. Pore size of the coating layer was under 10 ㎛. Permeability of foam ceramics is proportional to pore size. But coated ceramic filters have similar values without regard to pore size of supports. The permeability of supports was varied with pore size in the range of 600 × 10-13 ㎥ to 1000 × 10-13 ㎥. And for the case of the coated ceramic filter, it was about 200 × 10-13 ㎥. As a result of dust collection test with fly ash, the particle removal efficiency for the oeramic filter specimen was estimated over the 99.9%.

The amount of salt in radish after immersing in the salt solution was evaluated at various salt concentrations and soaking temperatures, and the changes of radish texture after immersed in the salt solution were interpreted with viscoelastic constants for a 3 element solid model by analysis of stress relaxation test data. The amount of salt diffused through radish was increased with increasing the salt concentration and soaking temperature. While the instantaneous stress, equilibrium elastic solid content and viscoelastic constants of radish were decreased as salt concentration and soaking temperature increased, the stress relaxed fast. However, viscoelastic constants was influenced by salt concentration more than by temperature, as did in diffusion coefficient. The rheological equation relating stress changes of radish after immersed in the salt solution at various conditions was suggested as a function of time.
