Recombinant Arabidopsis non-specific lipid transfer proteins (nsLTPs) was purified from yeast. In order to determine the effect of nsLTPs for an production of anthocyanin in perilla leaves, ‘Manchudlggae’ cultivar was grown at pots that had been applied with different concentration of nsLTPs. The anthocyanin content in AtnsLTP treated leaves increased above two-fold higher than that in control. Also chlorophyll content was increased 16%. It was presumed that AtnsLTPs could be applied to increase high quality of perilla leaves.

Porridge is one of the oldest recipes from Chinese emperor period, Porridge is made out of many kinds of granis and we concentrate on here ones that are made out of mostly rice, We find out now a day, porridge is fading out because it takes longer time to make one and usually people tends to thinks porridge is only for the patients, We try to figure out more variety of porridge by researching fifteen books. which are dated from sixteen century to 20 century, More specifically we focus on, in our research, recipes, materials that make porridge, materials that put fire on, pots that cook in, tools that handle with, purposes that make it, and effects that bring our after eat it.

AAL type 2 provides for the bandwidth efficient transmission of low bit rate, short and variable packets in delay sensitive application. The service object for these networks ranges from POTS to multimedia conference. In this paper, we present one possible architecture which common part sublayer for new AAL type 2. The proposed CPS function has been achieved with on a FPGA The proposed architecture is faithful to the standardization of ITU-T and ATM-forum recommendation The proposed architecture applies to variable packet length from architecture CODECs for cellular network.. It's maximum process capability is 155Mbps with 256 CIDs. The architecture has sync./async. interface to application block and UTOPIA interface is used for physical layer interface.

In this paper, we propose a new architecture of the Banyan switch for a high speed networking and the high speed parallel computer. The proposed switching network with a remodeled architecture is a newly modified Banyan network with eight input and output pots, respectively. We have analysed the maximum throughput of the revised switch. Our analyses has shown that under the uniform random traffic load, the FIFO discipline is limited to 70％. Therefore the result of the analyses shows that the results of the networking simulation with the new switch are feasible and if we adopt such as new architecture of the revised model of the Banyan switch, the hardware complexity can be reduced. The FIFO discipline has increased about 11% when we compare the switching system with the input buffer system. We have designed and verified the new switching system in VHDL.

This study was conducted to develop the clonal propagation technique through in vitro culture using by leaf sheath explants of Phalaenopsis grown in vitro. The highest frequency of protocorm-like body (PLB) formation was obtained when explants of leaf sheath were cultured on VW medium containing 30g/L sucrose, 500 mg/L activated charcoal, 150 mVL coconut water, 1 mg/L NAA, 1 mg/L 2ip and 2.5 g/L gelrite. The PLB formation rate of VW medium was highest followed by modified Hyponex medium, and lowest in MS medium. Plantlets induced from PLBs transferred to plastic pots including spagnum moss were well developed.

This paper presents the mesh selectivity of a net pot for common octopus Octopus minor for the sustainable resources management of common octopus. The filed experiments were carried out the total 10 times in the southern part of coastal sea in Korea from March to May in 2010 using net pots of five different mesh sizes (16, 18, 20, 22 and 26mm). The test of size selectivity, indicated a 50% selection value on the logistic master curve of 3.195, whereby 50% of individuals with a mantle size of approximately 70.3mm selected a mesh size of 22mm. Considering that 50% of common octopus entering sexual maturity have a mantle size of 70.6mm, the optimum mesh size should be equal to, or larger than 22mm.

본고는 `99 하반기 시범 서비스를 눈앞에 둔 WLL 시장전망 및 표준화 동향 소개를 목적으로 하였다. 기존의 음성/동회선으로 표현되는 가입자망(Access Network)은 유선망 제공 서비스의 무선망에서의 요구, 데이터 트래픽의 음성 트래픽 추월, 그리고 음성과 데이터 통합 서비스 요구 등 다양한 사용자 요구에 대응하기 위하여 새로운 전환기를 맞이하게 되었다. 그러므로 이와 같은 가입자망 진화 추세에 부응하고 가입자망의 경쟁을 도입하기 위한 정책으로 WLL(Wireless Local Loop)이라는 기술이 대안으로 고려되어지고 있다. 이 기술은 선진국에서는 신규사업자의 우회회선으로, 개발도상국에서는 POTS용으로 필요성이 대두되고 있으나 경제성 여부는 찬반이 일고 있다. 따라서, 본 논고는 ITU/AMD 조사에 기반하여 WLL 시장전망 및 경제성에 관하여 살펴본 후, 엔지니어링 입장에서 구현 기술 및 시스템 특성에 관한 표준화 동향을 소개하였다.

This study investigates prehistoric human subsistence and pottery use on the Korean peninsula through the organic residue analysis of archaeological potsherds. Ancient human subsistence is one of the core topics in Korean archaeology. However, due to the high acidity of sediments, which prevents the long-term preservation of organic remains, archaeologists have been short of critical information on how these early prehistoric dwellers lived. Ceramic vessels can contain well-preserved lipids originating from past culinary practices. For a better understanding of human subsistence on the prehistoric Korean peninsula, food-processing behaviors were reconstructed by analyzing ancient lipids extracted from a pottery matrix. The potsherd samples used in the analysis in this paper were collected from major prehistoric habitation sites. The results show that subsistence strategies differed according to both location and time period and reveal how organic residue analysis can contribute to a better understanding of prehistoric human subsistence strategies.

This study was conducted to investigate the different effects of ectomycorrhizal fungal (ECMF) species on the growth of seedlings of Pinus densiflora, and the effects of ECMF diversity on plant productivity. A total of five species of ECMF were isolated from root tips of pine seedlings collected from Mt. Songni and used as inocula. Pots containing pine seedlings were inoculated with either a single ECMF species or a mixture of five ECMF species. All of the seedlings formed ECM on their roots except for the control plants. The pine seedlings' growth responses varied by the different ECMF species. Also, pine seedlings inoculated with a mixture of five ECMF species showed the highest growth response. The results of the study suggest that the colonization of diverse species of ECMF will increase plant productivity, and the selection of suitable ECMF species could be an important factor for plant growth.

This study was conducted to develop the clonal propagation technique through in vitro culture using basal stem explants in Phalaenopsis hybrid grown in vitro. The highest frequency of protocorm-like body (PLB) formation was obtained when basal stem explants were cultured on VW medium containing 30g/L sucrose, 500 mg/L activated charcoal, 150 ml/L coconut water, 1 mg/L NAA, 5 mg/L 2iP and 2.5g/L gel rite. PLBs transferred to Hyponex medium were regenerated to plantlets. Plantlets transferred to plastic pots containing spagnum moss were developed and successfully acclimatized under greenhouse. The flower was bloomingly opened in plants regenerated from basal stem explants. The flower was not different from both mother plant and plant induced through clonal propagation of Phalaenopsis hybrid.
