Stick insect has several peculiarities like parthenogenesis, unique external features and dropping oviposition, so it is very hopeful to use for industrial insect. The oviposition was established by only female without fertilization with sperm of male which was not discovered during this study. The oviposition period was 37.3±14.9 days and the number of eggs per female was 41.5±16.5 eggs. The hatchability was 73.3% at 25℃and 66.7% after low temperature treatment(8℃, 60 days). The developmental periods and the length of egg were 100.9±4.2 days and 0.33±0.0cm, respectively, and the adult's life span was 49.7±16.0days. Differently other research which reported five nymph stage, the developmental stages of nymph showed five(62.9%) or six(37.1%) stages. The duration and the length of nymph increased according to the increase of nymph stage. Stick insect preferred the leaf of American locust, White oak, Chestnut, Bush clover in order but could be reared with food of the leaf of all these trees. Stick insects are herbivorus but made an attack each other when encountered in the small space. For sustaining mass rearing of stick insect, it is needed that the development of artificial diet and high density rearing method.
인체 피부 섬유모세포의 BK_(Ca) Channel에 대한 Sodium Nitroprusside의 효과

To investigate the presence of large conductance, Ca^(2+) activated K+ ( BK_(Ca)) channel in human fibroblasts and also examine the effect of nitric oxide (NO) on BK_(Ca) channels that may be modulated by cyclic nucleotides activations of protein kinase, we isolated human fibroblasts from genital skin. Cells of 4th ~5th passages were used for the experiments. The whole cell outward current was sensitive to NS1619 (a selective BK_(Ca) channels activator) and iberiotoxin (IBTX a specific inhibitor of BK_(Ca) channels). The mean single-channel conductance in symmetrical KCl (145 mM) was 238 ± 6 pS (n = 5). The cument was reversed at 0 mV, Ca^(2+) dependent and blocked by low doses of TEA. In cell-attached mode, SNP (1 mM) increased the NPo of the channel significantly. In inside-out configuration, however, not increased that indicating involvement of a soluble second messenger. The stimulation effect of SNP on BK_(Ca) channels was inhibited by ODQ, a soluble guanylate cyclase inhibitor pretreatment and pretreatment of KT5823, a specific PKG inhibitor. In conclusion, the present study suggest that SNP increased BK_(Ca) channels in human skin dermal fibroblasts and that this effect was mediated through a cGMP pathway.

Baculum elongatum has a long, thin shape that resembles a twig, propagates by parthenogenesis, changes body color, and drops eggs, all of which suggests its potential in the commercial market, especially as an educational pet insect. This study was carried out to determine the best hatching environment and an alternative or artificial diet for rearing B. elongatum to be developed as a commercial and educational pet insect. Oviposition was performed by females without fertilization by the sperm of males. The oviposition period was 42.2 ± 22.7 days and the number of eggs per female was 109.5 ± 70.5 eggs. The hatch rate was 73.3% at 25°C and 66.7% after low temperature treatment (8°C for 60 days). In nature, B. elongatum overwinters as an egg, but it can be assumed from the results that cold temperatures were not required for hatching. The hatch rate was 98.2% in the treatment using floral foam, fermented sawdust, and leaves. Clover(Trifolium repens) was an excellent diet as it was similar to the host plant and could be used as an alternative diet. The rate of reaching adulthood for the insects was 66.7% on an artificial diet containing 25% acacia leaves. For sustainable mass rearing of nymphs or adults of B. elongatum, a natural diet could be used such as acacia (Robinia pseudoacacia), white oak (Quercus aliena), chestnut (Castanea crenata var. dulcis), and bush clover (Lespedeza bicolor), or an alternative diet such as clover or artificial diet. To rear nymphs and adults of B. elongatum, natural diet such as acacia, white oak, chestnut, or bush clover leaves, or an alternative diet such as clover or an artificial diet can be used.

본 논문은 고속철도 환경에서 이중 이동 라우터를 이용한 끊김없는 핸드오버 방안을 제안한다. 제안한 방안은 철도차량의 앞과 뒤에 두 개의 이동 라우터를 배치하여 핸드오버 수행시기 차이를 이용한다. 이중 이동 라우터 중 하나가 핸드오버를 수행하더라도 다른 이동 라우터가 계속해서 패킷을 수신할 수 있으므로 네트워크 전체적으로는 끊김없는 서비스가 가능하지만, 두 개의 이동 라우터는 논리적으로 하나로 동작하게 된다. 수학적 해석 및 시뮬레이션 결과 제안한 방안은 핸드오버 시 서비스 중단 시간 및 패킷 손실을 방지할 수 있음을 알 수 있었다. This paper proposes a seamless handover scheme for high-speed trains using dual mobile routers to minimize service disruption time and packet loss during handovers. In the proposed scheme, each of the dual mobile routers is located at each end of the moving network for space diversity. One of the two mobile routers can continuously receive packets from its home agent, while the other is undergoing a handover, but they act as one logical mobile router. Analytical and simulation results showed that the proposed scheme could provide no service disruption or packet losses during handovers.
