The purpose of this research was to study the origins and the meanings of the Kokal (고깔). Comparative linguistic analytical approaches were employed to trace the development of the word, the Kokal(고깔). Results of this study revealed that the kotkal(곳갈, 곧갈) was a general term referring to a variety of head coverings in eh period of Choson Dynasty. This broad meanings of the Kotkal(곳갈,곧갈) of the Chosun Dynasty period has been changed to a narrow sense meanings a conical cap made of folds of the material, mainly used by some of the Buddhist monks in modern Korean. Also, the phonetic value of the Kotkal(곳갈,곧갈) of the Choson Dynasty period changed to the Kokal(고깔) in modern Korean. A variety of words for the Kokal(고깔) was found in the different languages such as Latin, English, French, Turkish, German, Mongolian, and Chinese. The examination and analysis of this study indicated that the origin of the Korean word Kotkal(곳갈,곧갈) or Kokal(고깔) and the meanings of it were derived from LL. Cuculla(monk's cowl)

This study was about three genus of Viola: V. rossii, V. japonica, and V. dissecta var. chaerophylloides which can live together under a deciduous forest canopy. The aim of the study was to directly compare reproductive characteristics of the three species under the same environmental condition. By taking a census of the morphologically different flowers, the results indicate that all three species opened chasmogamous flowers before the canopy of forest closed, but continuously opened cleistogamous flowers after the canopy closed. Numbers of seeds in a capsule followed an ascending order from V. rossii to V. japonica. Mass of seeds followed a descending order from V. rossii to V. japonica. Both results had statistical significance. In terms of characteristics of seed production, V. rossii has been adapted more than V. japonica, and V. dissecta var. chaerophylloides under the deciduous forest.

Commelina benghalensis L. and Commelina diffusa Burm. f. belonging to Commelinaceae, two species previously unrecorded as Korean flora, were collected in the lowlands of Jeju Island in Korea. Commelina benghalensis of the two species is different from others of Commelinaceae in Korea by having funnelform spathes fused at the proximal margin of involucral bracts and cleistogamous flowers. In addition, Commelina diffusa differ from others by having a three-valve capsule and lanceolate and a base cordate or rounded spathelike involucral bracts. The somatic chromosome number of Commelina benghalensis was 2n = 2x = 22 and the sizes of chromosomes were very small, ranging from 1.25 to 2.70 ${\mu}m$. However, the Commelina diffusa chromosome number exceeded 2n = ca. 100, and a precise count could not be obtained. These species are known to be distributed in tropical and subtropical regions of Asia and Africa below the latitude of Jeju Island of Korea.

햇무리(halo) 모양 코로나질량방출(coroanl mass ejection) 현상은 1970년대 후반 처음 발견된 이후, 그 물리적 본질에 대해 많은 논쟁이 있었다. 우주 망원경 SOHO LASCO의 고분해능 관측이후, 햇무리 모양은 시선방향에 나란한 방향으로 팽창하며 진행하는 고깔모양의 자기 구조(cone-shaped magnetic flux rope)가 2차원 관측이미지에 투영된 것으로 해석하는 것이 정설이다. 우리는 이러한 해석이 사실인지 관측을 이용해 검증하고, 타당한 물리적 해석을 찾는다. 이를 위해 STEREO 우주선이 SOHO에서 관측한 태양의 측면을 관측했던 2010년부터 2012년 관측자료를 사용하고, SOHO에서 관측한 햇무리 모양의 코로나질량방출 현상의 측면 모습이 예전의 해석대로 고깔모양을 보여주는지 STEREO 우주선의 관측자료와 비교한다. 우리는 햇무리 모양이 시선방향에 상관없는 이 현상 고유의 모양임을 확인 했으며 극자외선 관측결과와 수치계산 결과와 비교하여 이 햇무리 모양은 파동 현상의 결과임을 알았다. 이는 코로나질량방출 현상과 관련한 해석에 많은 변화가 필요함을 의미한다.

In this study we investigated the relationship between characteristics of vegetative growth of three species of Viola (V. rossii, V. japonica, and V. dissecta var. chaerophylloides) and light in order to explain how these three species could live together under a closed space in a forest. This studywas carried out at five sites in Mudeung-san (Mt.) on 1994, 1995, and 2000 and additional investigations were performed on 2007 and 2010 at the same sites. In order to find the relationship, three main investigations were conducted: counting number of individuals for each investigated year, measuring dry mass and counting developed leaves per plant, and finding presenting patterns of each species with reference to incidence of light. As a result, we found that three species could share the closed space in a forest because of their different adaptive strategies like V. rossii as Kstrategist, V. japonica as r-strategist, and V. dissecta var. chaerophylloides as an intermediator between two species.

'Geumhyang2ho', a new brown and labor-saving variety of Flammulina velutipes, was bred by spontaneous crossing between 'Geumhyang' and 'Garlmoe' during demonstration cultivation in bag culture farm of oyster mushroom in 2013. During bottle cultivation, the temperature was maintained at $16^{\circ}C$; the variety displayed good quality compared to the control ('Geumhyang'), without necessitating vinyl cone treatment. The time periods necessary for mycelial growth, fruit body growth, and primordia formation were 24 days, 11 days, and 8 days, respectively. The total cultivation period was 43 days, which was 2 days longer than that of the control. The pileus diameter was smaller, but the pileus thickness and stipe diameter were greater than those of the control. The pileus color was yellowish ivory, which was very similar to that of the control. The yield of 'Geumhyang2ho' was 118 g per 850 ml bottle, which was markedly lower than that for bottle cultivation with vinyl cone treatment. However, its good quality suggests the potential of the labor-saving bottle-based cultivation of 'Geumhyang2ho' without vinyl cone treatment in oyster mushroom farms.

This study focuses on the correlation between Kotgal and paper-folding. This paper first examines the meaning and history of Korean ancient Kotgal and then investigates relationship between Kotgal and Korean paper-folding culture which has been inherited in various ways. Throughout the study, literature research and analysis have been conducted along with empirical studies. The results of the study are as follows. First, it has been told that Kotgal was used a as a trident hat symbolizing the sky, land, and man, whereas Korean paper-folding is known as closely related to the folk beliefs which had existed since ancient times. From ancient times, the Korean ancestors expressed the Three Gods representing beauties of the nature, 'sky(Chun), land(Ji) and man(In)' on the conical hat and prayed for their wish to the heaven. Second, Kotgal has been evolved in various ways from ancient times through Goryeo and Joseon Dynasty to present. The form of Kotgal has begun with folding and this is closely related to the origin of Korean paper-folding, which is the Korean traditional craft. Third, the paper-folding tradition of Korea has been variously applied in the Korean culture such as rituals, life crafts and plays and expresses the unconventional philosophical concepts unique of Korea. In conclusion, this study evidently shows that the Korean philosophical ideas behind Kotgal which originated from ancient paper-folding are scientific and systematic.

This paper is extended the meaning and period of CONICAL HAT. That is, the race in Central Asia and Western Asia have worn the conical hat before Scytian appeared. One in conical hat puts on the clothes of two-piece style and has the lifestyle. a horse riding and nomadism. Besides the race originate into the Indo-European language family. On the whole the conical hat has relations with the region and is classified into two groups. Scytian and Klin-Yar style. First. the Scytian style of low hat forms the seam of two-piece and is discovered in Southern Russia. Central Asia and East-Northern Asia. Second, the Klin-Yar style of high hat forms the one piece and generally is discovered in Asia Minor and west of Altai. Until now the moaning of the conical hat has focused on the military. However, one in Central Asia and Western Asia is mostly a king. nobility and god. Therefore, in addition to the meaning of military. I estimate that the conical hat may be expressed as the noble status.
