  • Shin Hong-Gyun and his family have been in medicine for many generations as Korean Medical Doctors (KMDs). In 1919 when Shin Hong-Gyun was participating in an independence movement in Jang-Baek-Hyun, his younger brother Shin Dong-Gyun was killed by Japanese military police forces. This tragic incident triggered Shin Hong-Gyun to establish an army for national independence called , holding 200 young men, to serve in armed struggle against the Japanese Government with Kim Jung-Geon in May, 1920. In March 1933, Shin Hong-Gyun, as a military surgeon, led his men to the Korean Independence Army to fight a battle. Once he became a member of the Korean Independence Army, he, in fact, participated in few battles: Sadohaja, Dong-Kyung-Sung, Deajeonjayeong. Daejeonjayeong was a waypoint that the Japanese military needed to pass through in order to reach the Wangcheong area. Shin Hong-Gyun's independence forces had to endure painful starvation and heavy rain while hiding in ambush for long periods of time until the Japanese military would appear. Due to its summer rainy season, rainwater overflowed into their trenches and was filled up to the waist. Even worse, food stockpiles were low and the Japanese army did not appear for longer time. Shin Hong-Gyun's entire team suffered severe hunger and extreme cold. At this critical moment, Shin Hong-Gyun used his expertise as a KMD to find edible black mushrooms that grow wild in the mountains and use them to feed his men. This event led to the victory of the independence army at the battle of Daejeonjayeong. The purpose of the paper is to inform and highlight the forgotten history of Shin Hong-Gyun who was, both, a Korean Medical Doctor and a military surgeon.

  • All intra-specific hybrids among ASI $2172{\times}2104$, $2172{\times}2307$, $2186{\times}2172$ and $2186{\times}2307$ in P. salmoneostramineus produced pink fruiting bodies as like wild parental types. However, three hybrids of them between ASI 2186 and 2104 were white fruiting bodies. A new commercial strain "Noeul" of Pink Oyster mushroom was developed by intra-specific hyphal anastomosis. It was improved with hybridization between monokaryotic strain derived from ASI 2172 and ASI 2104. The optimum temperature of mycelial growth and fruiting body development were $25{\sim}30^{\circ}C$ and $19{\sim}24^{\circ}C$, respectively. The pileus was bright reddish pink. Commercial strain "Noeul" was as prolific as the more commonly cultivated Pleurotus ostreatus in the conversion of substrate mass to mushrooms using bottle cultivation. Mushroom cultivator can save money for mushroom growing on summer in Korea. Mushrooms should be picked when moderately young, and handled carefully so as to not bruise the brilliantly colored gills. This pink color makes marketing an interesting challenge depending upon the market niche.

  • In order to determine the effects of thinning on mushroom fruiting, microclimate and air temperature in Quercus mongolica forests, this study investigated changes in crown density, soil temperature, air temperature and throughfall in the natural Q. mongolica forest which was thinned by approximately 45% four years ago. The results showed that crown density was smaller than control by 6% from April to October, The soil temperature and air temperature in the thinned stands were significantly higher than those of the control by $1{\sim}2^{\circ}C$ until August and differences in air and soil temperature. The average daily temperature difference was higher than control by $0.2{\sim}0.7^{\circ}C$ until October. Throughfall from July to September in the thinned was approximately 135 mm higher than in the control. The maximum difference in throughfall per unit time was 3.5 mm/h. Soil moisture in the thinned site increased by approximately 5% compared with the control and reduced to the normal moisture after 4 days in both sites. 55 mushroom species were found in the thinned area between July and September. The thinned site contained 10 mycorrhizal mushrooms more than the control and 1 saprophytic mushroom species more than the control. Shannon-Wiener Index was 3.2, approximately 0.5 higher than the control. Tylopilus neofelleus, etc., occurred in the thinned site more quickly, but Aaricus subrutilescens, Clitocybe sp, occurred later. In the thinned site, the dominance of Tylopilus neofellelus and Armillaria sp. increased approximately 6% and 30% and yield about 1.5 times and 20 times, respectively. In conclusion, thinning in the Q. mongolica forest increased the soil and air temperature, soil moisture, throughfall and the diversity of mushroom species, and advanced the period of occurrence, and increased dominance and yield of some mycorrhizal mushrooms and Amillaria sp.

  • Three edible species, e.g. Lyophyllum sp. and Armillaria mellea introduced from Japan in 1979 and Auriaularia auricula-judae from Taiwan in 1978 were selected for artifcial cultivation. The media, MSDS for Lyophyllum sp, MHS and PDS for A. auricula-judae, and MSDS and MHS for A. mellea were selected. The range of optimum pH of Lyophyllum sp. was 6.0 and pH 8.0 for A. auricula-judae and pH 6.0 to 7.0 for A. mellea. The range of optimum temperature for the mycelial growth of Lyophyllum sp. was 25 to $30^{\circ}C,\;30^{\circ}C$ for A. auricula-judae and $25^{\circ}C$ for A. mellea. When the moisture content 75 to 80% (w/w) in the substrates, the mycelial growth of Lyophyllum sp. and A. auricula-judae, was rapid. 65% (w/w) for A. mellea. As the spawning substrates, wheat for Lyophyllum sp. oak sawdust for A. auricula-judae and poplar sawdust for A. mellea were selected, respectively. In this experiment, yields of Lyophyllum sp. and A. auricula-judae were high on the poplar sawdust added 20% (w/w) of rice bran. Lyophyllum sp. and A. auricula-judae for sources of new edible mushrooms seems to be possible.

  • Lentinula edodes is one of the most widely consumed edible mushrooms in Korea. Mating in L. edodes is regulated by a tetrapolar system, and two unlinked genetic loci, A and B, are known to be major determinants of the mating types, as reported in other heterothallic basidiomycetes. The A locus of L. edodes encodes a pair of homeodomain (HD) transcription factors. The highly variable N-termini of these HD transcription factors contribute to the diversity among the A mating types. In this study, we developed a cleaved amplified polymorphic sequence (CAPS) marker to discriminate 11 different A mating type alleles predominant among both cultivated and wild strains. Amplification of the variable region of the A locus followed by digestion with HaeIII and EcoRI restriction enzymes enabled successful discrimination among the 11 A mating type alleles. We also evaluated the applicability of this method in the identification of two A mating types of a dikaryotic strain.

  • Shin Hong-gyun was born on August 20, 1881. The second son of Shin Tae-geom (申泰儉) in Sangsang-ri, Sinbukcheong-myeon, Bukcheong-gun,Hamgyeongnam-do. His family had been practicing East Asian medicine as a family business. At that time, the families of East Asian doctors who passed the general examination of the Joseon Dynasty had been continuing the East Asian medicine business from generation to generation. Starting with exile in North Gando in 1911, he was located in Wangga-dong, 17 Doo-gu, Changbaek-hyeon. In 1915, he met General Choi Un-san in Bongo-dong, treated the soldiers suffering from cellulitis, and participated in the training process to prepare for the upcoming anti-Japanese war. However, because of a growing difference of opinion with General Choi Woon-san, Shin Hong-gyun left Bono-dong after a year and mets Sorae Kim Jung-geon and joined the founding of Wonjonggyo and Daejindan, an anti-Japanese armed group. It is said that Shin Hong-gyun established many schools in Korean villages destroyed by the Gyeongshin disaster and 14 schools were established under the names of Wonjonggyo and Daejin. After the Japanese established the puppet Manchukuo in 1931, the Manchurian Defense Forces were formed. Koreans and Chinese immigrants to Manchuria worked together to carry out a joint Korean-Chinese anti-Japanese operation towards the Japanese Empire. In 1933, 50 of the Daejindan members joined the Korean Independence Army, and among them, Shin Hong-gyun began to work as a medical doctor in earnest. During an ambush in Daejeonryeong Valley, he could not get a proper meal and, to make matters worse, got wet in the rainy season, so the situation was a challenge in various ways. At this time, Shin Hong-gyun showed his knowledge of herbal medicine, picked black wood ear mushrooms that grew wild in the mountains, washed them in rain water, and provided food to the independence fighters and relieved them of hunger. After the Battle of Daejeon-ryeong, the Japanese army's suppression of the independence forces intensified, and most of the independence fighters escaped from the Chinese army's encirclement and were scattered. Ahn Tae-jin and others led the remaining units and continued the anti-Japanese armed struggle in the forest areas of Yeongan, Aekmok, Mokneung, and Milsan.

  • 1. For the types of boiled rice, there were 1 type of bap, 1 type of jebap cooked with glutinous rice, 13 types of boiled rice cooked by mixing grains and nuts such as daemakban, somakban, jobap, cheongryangmiban, jobap, gijangbap, yulmubap, hyeonmibap, boribap and patmulbap as well as patbap, congbap, byeolbap and bambap etc as ogokbap. Also, there were 12 types of bap cooked by mixing herb medicinal ingredients such as cheongjeong, oban, boksungabap, gumeunsaekbap, hwanggukgamchobap, yeongeunbap, okjeongbap, gogumabap, dububap, samssibap, dorajibap, gamjabap, songibap and jukshilbap. There were 7 types bap cooked as unique one bowl dish at the present as bapby mixing fish, meat, shellfish and milk as ingredients are hwangtang, gyejanggukbap, janggukbap, gulbap, kimchibap, chusaban and bibimbap, etc and the types of bap that have been analyzed are 34 total. 2. For the food ingredients used in bap types 23 types of miscellaneous grains, 5 types of nuts and 11 types of meat, 6 types of fish, 35 types of vegetables, 2 types of fruit including pears or peaches were used. Garlic wasn't used perhaps because of it being boiled rice 3. Types of Sap by Cooking Methods. (1) The ssalbap was cooked by first boiling water, putting in rice grains and boiling hard to be cooked as overcooked bap (rice). (2) The japgokbap (boiled cereals) has used buckwheat, barley job's tear, etc to be boiled down by soaking the ones with large grains (beans) first in advance to be boiled down or cooked by crushing into fine pieces. The red bean, etc was boiled down in advance or placed at the bottom of pot by cutting into two pieces while jujube or nut was cut into three pieces to cook the bap by pouring a lot of water and mixing other ingredients. (3) The gukbap (soup boiled rice), etc were cooked by squeezing out the yellow chrysanthemum that has dried chrysanthemum to cook the boiled rice by putting in rice and gukbap, meat or bones, etc were boiled down for a long time and decorated with meat or wild greens by mixing the bap in the meat juice. For gulbap (oyster boiled rice), etc, it was cooked as ingredients were stir fried in advance or washed and put in when the bap was about half cooked. (4) For bibimbap (mixed boiled rice), after the bap was overcooked first with rice, the wild greens were mixed lightly with bap beforehand, then the wild greens, decorations and garnishings were laid above rice and red pepper powder was sprinkled. (5) Namchok leaves, etc were boiled to cook the boiled rice with rice after being cooled while namchok stem and leaves were pounded to make juice and cooked the bap with rice. The peach, lotus root and yams were cut into fine pieces to be put in together when rice was about half done. The bellflower was soaked in water to be boiled down for a long time while potatoes and pine mushrooms, etc were cut into fine pieces to cook the bap (boiled rice) with rice.

  • A edible mushroom, Clitocybe maxima (Lentinus giganteusis) commercially cultivated in China and Taiwan. However, the researches of cultivation and cultural characteristics were not reported in Korea. In this study, we conducted on cultural characteristics and artificial cultivation of C. maxima. Six isolates were collected from China(3 isolates, commercial strain), Taiwan(1 isolate, commercial strain) and Korea(2 isolates, wild type). C. maxima and L. giganteus collected in China and Taiwan, respectively, are the same in China and are estimated to be of the same species as cultured characteristics. The mycelial growth of the collected strains was not significantly different in agar medium but it showed the best growth in YPMG in liquid culture. Optimum temperature for mycelial growth and induction of fruit body were 25℃ and 30℃, respectively. In order to artificial cultivation of C. maxima, cultural characteristics and artificial cultivation were carried out using agricultural by-products and forestry by-products materials. Mycelial growth was suitable in rice straw, cottonwood sawdust, corncob and rice seed medium, and it was selected as a cultivation medium. The suitable medium for artificial cultivation of C. maxima was selected to mixed medium 2(compounding ratio(v/v): 55% of hardwood sawdust, 5% of cottonseed pellets, 10% of cottonseed, 15% of beet pulp, 15% of swollen rice husks). It took about 30 days to be able to harvest, it was faster than oyster mushrooms. The cultivation period was about 30days. A isolate, CMA-002 was not initiation to fruit body primordiuma on the used cultivation substrate. Other 5 isolates were initiate and development to fruit body on the substrate used in this study. The strain CMA-003 was initiated to be fruiting body by 8~10 days after induction of fruiting body in all of the substrates. Isolate CMA-003 was generate to a bundle fruit body. Other isolates, however, were form fruit body individually. The CMA-003 strain was likely highly recommendable strains for farming. The optimum conditions for the induction and growth of C. maxima fruit body were 25~30℃, 8 hr illumination per day with white fluorescent lamp, 90~95% relative humidity, and 1,500 ppm of CO2 concentration in a cultivation room.
