The oyster mushroom is a widely cultivated edible mushroom in Korea. It is a regionally specialized crop in Gyeonggi-do, where 68% of the national production is produced. The present study was conducted to develop a new, highquality cultivar with stable cultivation. ‘Manseon’ is a new variety of oyster mushroom suitable for bottle culture. It was produced by mating monokaryons isolated from ‘HB-18’ and ‘P15159-16’. The optimal temperature for ‘Manseon’ mycelial growth was 26–29 °C on potato dextrose agar (PDA) medium and for primordia formation and the growth of fruit bodies the optimal temperature was 18–19 °C on sawdust medium. Spawn running required 30 d, primordia formation required 4 d, and fruit body growth in the bottle culture required 4 d. Regarding the characteristics of the fruit bodies, the pilei were round and dark grayish brown, stipe color was white, and stipe shape was short and thick. The yield per bottle was 192.7 g/1,100 cc, which was 9% higher than that of the control strain (Suhan-1ho). The physical properties of springiness, cohesiveness, gumminess, and brittleness of stipe tissue were 87.9%, 77.4%, 445.1 kgf, and 389.6 kgf, respectively.

This paper deals with architectural activities related to Korean society in Jichang district in North East China, focused on the articles of Manseon-ilbo published there during the Japanese colonial period. Construction-related contents in the area closely connected with topical interest, publicity, and enlightenment as a local media source provide positive grounds about pending issues in colonial situations. This paper handles with articles issued in the 1940's newspapers just before the Pacific War. At that time Japanese enter in the Chinese continent, and construct a stable basis in the intimate association with Germany and Italy, countering against the United State. Among articles regarding architecture, most of contents are based on healthcare and public facilities, and urban planning. Overwhelmingly the most popular articles are about new constructions of educational facilities and residential matters. The shortage of goods and the excessive concentration of population resulted in urban and house problems, which were particularly much more serious in Korea society. Such social atmosphere made all activities regarding building constructions, in particular educational facilities, in civil level rather than the helps of the Japanese colonial government. Thus, through education and house matters we can read a slice of Korean society to survive in the colonial environment of Jichang district.
