Relationships between pine-mushroom(Tricholoma matsutake) yield and important climatic factors for the yield(such as monthly precipitation, relative humidity, temperature, and radiation percentage) were examined to find out limiting factors for pine-mushroom production and to develop a method for overcoming the factors by analyzing the yield and climate data for 17 years collected from 18 main regions of pine-mushroom production. Although there were variations among the production regions, climatic condition of September was the most significant factor for pine-mushroom yield in general, and the degrees of importance of each climatic factors were different among the production regions. Mean minimum temperature of September was positively correlated with pine-mushroom yield($$r^2{\geq_-}0.41$$) at the 1% level, of which were 9 regions such as Youngduck, Uljin, Samchuck, Bongwha arid so on. In these regions, vegetation control was expected to be effective for pine-mushroom production by allowing much sunlight penetration to the pine stand, which may increase soil temperature and keeping the temperature around the fungal colony in soil. Precipitation during September was positively correlated with pine-mushroom yield($$r^2{\geq_-}0.41$$) at Namwon, Moonkyung and Sangju. Thus, irrigation around fungal colony in dry soil during September would be effective for enhancing mushroom yield at the regions. Pine-mushroom yield of 1994 was quite low, similar to that of 1993, due to serious drought. In this period, we could manifest the possibility of enhancing pine-mushroom yield by irrigation for overcoming drought at Moonkyung and Keochang regions.

Lithium has only a minimal effect on basal glucose transport activity, instead that lithium markedly increased the sensitivity of glucose transport to insulin by increasing in insulin induced glucose transport activity. And Lithium increases in insulin responsiveness as well. Previous studies has reported this enhancement of lithium to stimulate the glucose transport process is not only limited to insulin, it also induce the increases in the sensitivity of glucose transport by submaximal contractile activity. The preliminary study, however, leads that Lithium possibly improves the responsiveness of glucose transport with maximal muscle contraction. In this study, we investigated the effect of Lithium on contraction for the maximal glucose transport. For the purpose of this study, Epitrochlearis muscles of SD rat were isolated and treated Lithium with electric contraction and/or insulin to activate the maximal glucose transport. The results support that Lithium improves the responsiveness of glucose transport through potentiates contraction and/or insulin induced-glucose uptake in muscle. Consequently Lithium treated with muscle contraction and insulin has the important potential to improve the insulin resistance and diabetes.

The environment of IT is, currently, on its developing process to the period of web 2.0 and mashup which not only enable computer and internet to be utilized like the water or the air, but also be a new motivating force for its advance. One of the biggest changes of the industry that lies ahead is consolidated transportation. However, no party outstands as the leading party for nationwide improvement of logistics, nor does the right analysis and design for it. Therefore, successful nationwide logistics model is yet to exist. This study provides individual parties, which consider consolidated transportation model as their implementation and design of the framework, with instructions for logistics information system so that they could be competitive in the market. It also helps companies collect user requirements for logistics information system consolidated transportation, and utilize it for its development. Finally, the study provides a implementation and design of pilot system for consolidated transportation model.

오늘날 세계화와 정보통신 분야의 기술혁신으로 기업들의 경영활동 영역이 점점 글로벌화 되어가면서 물류산업의 환경도 급격히 변화해 나가고 있다. 세계적으로 확산되고 있는 인터넷망이나 물류망은 시간과 거리의 제약을 완화시켰으며, 고객들의 정보와 상품에 대한 접근이 쉬워짐에 따라 기업에 대한 고객욕구가 다양해지고 있는 실정이다. 이러한 경영환경의 변화에 따라 우리 기업들은 보다 경쟁력 있는 물류서비스를 고객에게 제공하기 위하여 물류 서비스의 유연성 개선, 물류 전문 인력 확보 등에 힘쓰는 한편 물류 부문의 취약성을 극복하기 위한 물류자동화 시스템 도입 등 다양한 방안을 강구하고 있다. 현재 도입된 수배송 관제 시스템은 GPS를 기반으로 하고 있다. 그러나 기존의 GPS를 이용한 관제 시스템은 위치 정보만 수신하여 위성의 사각지역 또는 실내에서 작동이 잘 되지 않는 문제가 있다. 이러한 문제를 해결하기위해 본 논문에서는 스마트폰을 사용한 수배송 관제 시스템을 설계하였다. 스마트폰은 GPS와 3G통신 모두 이용하여 양방향으로 통신할 수 있으므로 기존의 GPS를 이용한 단방향 수배송 관제 시스템보다 정보를 정확하고 효율적으로 관제할 수 있다. 제안하는 시스템은 물류 수배송 상에서 발생되는 데이터를 실시간 모니터링이 가능해야하며, 관리자와 수배송자간의 신속한 정보 전달을 통해 배송조건을 최적화시키고, 물류의 흐름을 제어하여 배송 시에 발생하는 문제에 대한 신속한 해결을 통해서 배송시간을 최소화하는 것이 목적이다.

The antibacterial activity from Tricholoma matsutake extracts were confirmed by minimum inhibitory concentration (MIC) test against various bacteria. Tricholoma matsutake extracts was applied for manufacturing low salted Jeot-gal with sodium DL-malate and sodium nitrite as food preservatives. Due to antibacterial activity from Tricholoma matsutake extracts, MIC of sodium DL-malate and sodium nitrite were significantly reduced to 0.025 g/L and 0.25 g/L, respectively. As a result of this study, a premium low salted Jeot-gal can be developed with low concentration of food preservatives by adding Tricholoma matsutake extracts.
