  • Medicinal fungi, taken whole or as various forms of extracts, have been used to alleviate, cure or prevent human ailments since pre-historic times. In particular, Asian cultures have incorporated a variety of mushrooms into their medical practices. Chemically pure, bioactive metabolites from fungi have been a mainstay of modern pharmacological research and in addition to antibiotics, include anticancer agents, immunosuppressants, enzyme inhibitors, antagonist and agonists of hormones, and a variety of psychotropic substances. However, to date not many studies have focused on the possible health benefits of odorant volatile organic compounds (i.e., gas phase compounds). An analysis of these compounds for their health related effects will expand the range of compounds available for the treatment of chronic and acute diseases. This review highlights phenolic acids and monoterpenes from Asian medicinal mushrooms (AMMs), which not only produce pleasant odors but also have antioxidant and antibacterial effects. Odorant bioactive volatile phase compounds from medicinal mushrooms remain an essentially untapped source for future medicines, and AMMs remain a promising resource for future pharmacological research.

  • New Seoul Town is a new town in Seoul Mapo-Gu, Which is planed by Seoul metropolitan government. There are Nanji Waste reclaimed land and Seoul world-cup stadium, which is under construction in the new town. This study is executed for urban nature conservation by assessing the biotope in the new town. The biotope map is mae by the selective mapping method, and assessing the biotope is executed by a quick method, which is originated with R. Wittig and Scheriber(1983). The assessment criteria include the period of development, area, rarity and variety of habitat condition. In the result from this study, biotope type of the new town is classified eight types, and all biotope type is valuable for nature conservation. The reason of this result is because of little natural area which is rice field, farm field, forest, swampy land, etc, except New Seoul Town, in Seoul Mapo-Gu. And so, Biotope in New A Seoul Town, must be conserved and restored in new town urban planning.

  • In order to develop a new variety of rice that adapts to the climate of Aomori prefecture and possesses characteristics suitable for production of high quality Japanese sake, artificial cross experiments were executed between Yamadanishiki, which is widely used nationwide as an authentic variety of rice for sake production, and Hanafubuki, which was peviously developed by Aomori prefecture. An excellent hybrid, named Hanaomoi, was selected and fixed by a series of selection experiments and systematic cultivation. Unpolished Hanaomoi rice contained less amount of protein than Yamadanishiki and Hanafubuki. Unpolished rice of Hanaomoi was harder than Yamadanishiri and Hanafubuki, therefore polishing treatment was done in high yield and one could obtain a high degree of polish on the rice(namely 40% polishing). These features are advantageous to production of high quality of sake.Test brewing using 40% polished Hanaomoi gave rise to a characteristic sake that contained a slightly higher amount of alcohol and flavor components than Yamadanishiki and Hanafubuki. Sensory tests concluded that sake from Hanaomoi was as superior as the one from authentic Yamadanishiki. Hanaomoi is a promising variety of rice suitable for production of a high quality sake exclusive to Aomori prefecture.

  • 본 논문에서는 게이미피케이션 요소(목표, 경쟁, 보상) 중 '보상'에 주목하고, 리얼 버라이어티 쇼에 적용된 실제 사례를 연구한다. 일상적이고 사소한 보상을 주는 <1박 2일>, 비일상적이고 특별한 보상이 있는 <슈퍼스타K>, '고유한(Vernacular)' 보상이 드러나는 <윤식당>을 분석했다. 그 동안 구체적인 보상과 달리, 추상적인 성격의 고유한 보상은 약한 게이미피케이션 효과를 가져 올 것으로 여겨졌다. 그러나 비가시적인 보상에도 불구하고 <윤식당>의 출연자는 각자 개인적이고 주관적인 보상을 받았다 느꼈고, 서사구조의 완결성 또한 강화되었다. 이 결과는 리얼 버라이어티 쇼가 새롭고 다양한 보상 구조를 가질 수 있음을 보여준다.

  • All of silkworm varieties reared in farmhouses are first generation hybrids, for the production of these hybrid silkworms precise and labor-saving sex discrimination is necessary. The new variety "Hanbyeolnue" is biparental sex-limited larval marking yellow cocoon variety which was bred from biparental sex-limited strain of Japanese originated Jam 319 and Chinese originated Jam 320. Productivity test of Hanbyeolnue in 2015 showed high healthiness and short larval period. The Hanbyeolnue was evaluated as an excellent variety which can be utilized for special purpose silkworm such as male pupae or Cordyceps production.

  • Tobacco mosaic virus (TMV), TMV-common strain, causes severe damage on flue-cured tobacco in Korea. As the results, breeding programs were conducted to transfer the TMV resistance from NC567 to other cultivars. Advantage of F1, hybrid may not lie only in their heterotic value but also in directly combining of valuable dominant traits, e.g. for disease resistance, either in pairs or as groups already assembled in the two parents. A new TMV resistant flue-cured tobacco variety KF114 was developed from a cross as maternal parent MSNC567 and NC82 at the Suwon Experiment Station. KF114 was more vigorous growth characteristics in early stage than that of NC82, standard variety in Korea, and other characters were similar to those of NC82. It os high resistance to TMV, but bacterial wilt(Pseudomonas solanacerum) and black shank (Phytophthora parasitica var. nicotianae) is comparable to NC82. It should adapt well to the flue-cured production area and can reduce premature flowering under unfavorable weather conditions. Yield of KF114 is 1% to 5% higher, and nearly equal in value per KG compared with NC82. This variety, F1 hybrid, met acceptable standards for chemical and physical characteristics of cured leaf and high ranked good smoking taste by panel members in Korea Ginseng and Tobacco Research Institute.

  • The physiological characteristics, growth, and yield of each regional rice variety ('Odaebyeo', 'Saechucheong', 'Ilmibyeo') were investigated depending on the impact of changes in temperature and CO2 concentration. Experiments were conducted with a control group, which reflected atmospheric CO2 concentration and temperature, and treatment groups, in which the CO2 concentration and temperature were increased by 250 ppm and 2.0℃ from those in the control group. The results showed that the increase in CO2 concentration and temperature reduced the growth and yield of the rice 'Odaebyeo', but did not substantially change the productivity of the 'Saechucheong' and 'Ilmibyeo'. The increase in CO2 concentration and temperature increased stomatal conductance and rate of transpiration of the 'Odaebyeo' variety, thereby decreasing its water use efficiency (WUE). In contrast, the increase in CO2 concentration and temperature increased the photosynthetic rate and WUE of the 'Saechucheong' and 'Ilmibyeo' varieties. The gradual change in climate is considered to directly affect growth and development of rice and diversely affect the productivity of each variety. Therefore, it is necessary to implement technological development, select regionally optimal rice varieties, develop new rice varieties, as well as conduct long-term monitoring of each rice variety for climate adaptation to counter global warming.

  • 느타리버섯(Pleurotus ostreatus)의 품종 육성을 위해서 는 많은 노력과 시간을 필요로 하고 있어, 최근에는 분자 육종방법으로 마커를 이용하여 빠르고 정확하게 교잡주를 선발하고 있다. 본 실험에서는 육종효율을 증진하기 위해 교잡효율이 높은 Di-Mon 교배방법으로 부친의 핵과 모친의 미토콘드리아를 가진 세포질전환 교잡주를 선발하였다. 느타리버섯 수한3호와 흑변이체의 교잡종인 '다굴'의 이핵균주에 춘추2호의 단핵균주와 교잡하여 120여개의 교잡주를 얻고 여기에 1차로 미토콘드리아 microsatellite DNA 마커 (MtPO1)를 이용하여 단핵균주 춘추2호의 미토콘드리아 밴드를 형성하는 교잡주 80개를 1차 선발하였다. 선발된 80균주중에서 URP 프라이머를 이용하여 '다굴'의 2핵균주 핵 DNA 패턴을 가진 26교잡주를 선발하였다. 이 중에서 수량성이 우수한 3개 교잡주의 자실체 특성을 조사한 결과 초발이일수가 2일이나 빠르면서 수량성이 좋은 품종을 선발하여 '천화심'이라 명명하였다. 천화심은 수량이 높으면서 여름에도 재배가 가능해 춘추2호의 약점을 보완함으로써 춘추대체품종으로도 재배가 가능하리라 본다.
