  • Noticed that large number of the Korean white pine (Pinus koraiensis S. et Z.) has lost its typical excurrent tree from by removal of apical shoot in the process of cone harvesting, the investigation and analysis for the species were made on the basis of the relationship among DBH, total height, merchantable height, and merchantable volume, compared with normally grown Japanese larch (Larix leptolepis Gordon). One hundred sample trees for each species were selected in the same aged stands for the study. Results have indicated that the pine has shown abnormal height growth pattern mainly by the disturbance of external artificial force. The pine's forked and/or crooked stems by the reason lave led the result of less merchantable volume in the same DBH classes. Consequently, the pine would have undesirable tree form in terms of timber production, unless free from apical shoot disturbances. Considered to the merit of the Korean white pine that can produce timber and pine nuts, management alternatives for the pine stand were suggested to achieve maximum rate of return for the silvicultural investment.

  • We found about cultivation light environment conditions of Neolentinus lepideus. For the high quality of N. lepideus, lights-out was useful. In the lights-out, the diameter of pileus of N. lepideus was smaller, and the length and the thickness of stipes were longer and larger than in that of lighting. At the LED effect, the orange and red LEDs prolonged the cultivation period in N. lepideus. The yields of N. lepideus under the white, blue and green LEDs were higher, and the number of available stipes of N. lepideus under the white and blue LEDs was higher than that of other LEDs. The diameter of pileus of N. lepideus under the white, blue and green LEDs was higher, and the length and the thickness of stipes under the orange and red LEDs was higher than those of other LEDs.

  • In this study power requirements to saw shoots with circular saw were determined by measuring and analyzing the required maximum torque to provide the information for the mechanization of Korean pine cone harvest. Two levels of feed rate of shoots, 10.4mm/s and 20.8mm/s, three levels of sawing speed 5.8㎧, 11.6㎧, and 17.4㎧, and 14 levels of shoot diameter from 7.7 to 18.1mm were used as variables. 1) The maximum torques were significantly affected by all three variables. The average maximum torque, 18.2 N-cm for feed rate of 20.Bmm/s was greater as much as 80% of 10.1 N-cm for feed rate of 10.4mm/s. 2) As the sawing speed was increased from 5.8㎧ to 11.6㎧ and 17.4㎧, the maximum torques were decreased to 14.8N-cm, 8.5N-cm, and 7.IN-cm, respectively when the feed rate was 10.4mm/s. The maximum torque ranged from 4.5 to 19.3N-cm as shoot diameter increased from 7.7 to 18.1mm. The minimum power requirements to saw shoots of 18.1mm with circular saw was 30W for the feed rate of 10.4mm/s. 3) The maximum torques were 28.6N-cm, 14.6N-cm, and 11.4N-cm when sawing speeds were 5.8㎧, 11.6㎧, and 17.4㎧, respectively when the feed rate was 20.8mm/s and these torques were increased as much as 93%, 36%, and 61% of those for the feed rate of 10.4mm/s. The maximum torque increased from 9.7N-cm to 30.7N-cm as shoot diameter increased from 7.7 to 18.1mm. The minimum power requirements to saw shoots of 18.1mm was 54W which was 1.8 times of 30W for the feed rate of 10.4mm/s.

  • The changes in the concentration of toropherol and carotenoid in pinenut oil at various stage of refining are studied during autoxidation. The oxidative stability of pinenut oil decreased with the refining degree increased. The tocopheol content of total crude oil was 55.51mg/100g oil and $\alpha$, ${\gamma}$and $\beta$-tocopherol in the crude oil were 25.48mg, 23.94mg and 6.99mg in order, respectively. The amount of $\delta$-tocopherol was trace. The concentrations of $\alpha$, ${\gamma}$ and $\beta$-tocopherol in pinenut oil after degumming or alkaline refining were 23. 85mg, 19.79mg and 6.12mg or 24.08mg, 24.04mg and 5.33mg, respectively. The content of f-carotene was 0.63% of total unsaponifiable materials and that of lycopene was trace. The concentrations of carotenoids and toropherols in pinenut oil decreased while autoxidation progressed. Degrees of destruction of carotenoids and toropherols. were significant at first stage of oxidation. Decrease in $\alpha$-toropherol was found to be faster than that in $\alpha$, ${\gamma}$-tocopherol during oxidation.

  • This study suggests a new women's upper clothing based on traditional Korean costumes that utilize the Jatmulim. The Jatmulim is an example of the skill found in conditional Korean costumes and is of a small triangular shape. Jatmulim was developed in size, shape, and arrangement through the method of making and using children's Durumagi, the dancer's or shaman's Mongduri, and modern works. A total of five pieces of different women's clothing were suggested by applying the developed Jatmulim. In the first piece, the clothing is a woman's sleeveless blouse based on the construction of the Yoseon-Cheolik from the Joseon period and made with a larger sized Jatmulim in the back of the neckline and shoulders. In the second piece, the clothing is designed for a woman's jacket based on the Bansuui of the Joseon period with rectangular Jatmulim in the front neckline and at the end of the sleeves. In the third piece, the clothing is designed for a woman's sleeveless blouse based on the Danryeong with rectangular Jatmulim in the neckline. In the fourth piece, the construction of the Jeogori is applied to the clothing for making a woman's jacket that has a bigger sized Jatmulim in the front part as a decoration. In the fifth work, the clothing is designed for a sleeveless blouse based on the Dapho with a different sized arrangement of the Jatmulim in the neckline.

  • This study was carried out to elucidate suitable supplementary nutrition for Neolentinus lepideus cultivation. The main substrate for cultivation was douglas fir sawdust, and supplementary materials for experiment were corn meal, corn hull, corncob, beet pulp, and potato starch. The higher amount of total nitrogen source was showed in corn meal (0.45%) than any other nutritive materials. Incubation ratio and cultivation period showed the best 97% and the shortest 43 days on medium with corn meal substrate. The fruit body yield and biological efficiency on medium with 10% corn meal were highest 122 g/1 kg and 35%, respectively. Factor analyses concerning fruiting yield showed total nitrogen source (r = 0.95) and crude fat (r = 0.65). These results are recommended that N. lepideus cultivation is corn meal material as the source of the supplementary nutrition and total nitrogen source as the factor of fruiting body yield on the Douglas fir sawdust medium.

  • In Sasang Constitutional Medicine, pine trees have been used as medicines for Taeyangin and a pine-nuts tree for Taeumin. However, there has been some misunderstandings in interpretation as the Koreans referred to back(栢) as pine-nuts tree as well as cheukback(측백) tree. Also, we have disputed over how to translate songback(松栢). Regarding this dispute, 1 came to the following conclusion based on a research with exactitude. 1. Songja (松子), Songjain(松子仁), Songsil(松實) means Pinus Koraiensis(잣), not a pine .one. 2. Backja(栢子) is a fruit of Cheukback(측백) tree, not of a pinus koraiensis(잣). 3. Some part of 'yulsunjun(列仙傳)' quoted to explain pine-nuts in Bonchogangmok(本草綱目) was misrepresented. 4. In regard to the record that a court lady of Chin(秦) Dynasty lived for bundle of years, Galhong(葛洪) made a mistake by saying that she took pine needles and a Pinus Koraiensis in 'Pobakja(抱朴子)', while saying that she took pine needles and leaves of Cheukback(측백) tree in 'Joohoobigeupbang( 後備急方). Also He made a mistake by saying that took pine needles and leaves of cheukback(측백) tree in Bonchogangmok(本草綱目). 5. Songback(松栢), which was referred to in the Analects of Confucius(論語) and the historical annals(史記), should be understood as an old pine tree with a hard quality of the lumber and evergreen, .rather than 'a pine tree and a pine-nuts tree' or 'a pine tree and Cheukback(측백) tree'. 6. Although 'Songback(松栢) mentioned in a book on medicine were sometimes considered as 'a pine-nuts tree' and 'Cheukback(측백) tree' or 'a pine tree and .Cheukback(측백) tree,' it should be regarded as an old pine tree in most cases.

  • We aimed to develop a new variety of Neolentinus lepideus from about forty strains by bag culture. To this end, "Solhyang" which means pine smell in Korean was selected as a new commercial variety of N. lepideus. N. lepideus have yellow pileus and pine smell, which characteristics make a favorable impression on the far east Asia, Korean and Japanese. The optimum temperatures for mycelial growth and fruit body development ranged $26{\sim}32^{\circ}C$ and $18{\sim}20^{\circ}C$, respectively. The required periods of mycelial incubation and fruit body growth were 30 days and 7 days, respectively. The fresh weight of fruit body was 115g/kg with pine sawdust and corn meal power(9:1, v/v) substrate.
