In the early Joseon dynasty, the meritorious vassals' portrait of Jeokgae (1467, 1476), Jeongguk (1506)·Jeongnan (1507), and Wisa (1545) were defined as the 2^nd period of the official uniform, in which the acheongsaek HeukDanryung appeared and settled. A total of seven portraits were analyzed, including three portraits of Jeokgae (1467, portrait production 1476) Son-so, Oh Jachi, and Jang Malson, and four portraits of Jeongguk (1506)·Jeongnan (1507) Yoo Sunjung, Hong Gyeongju, Lee Woo, and Yoo Hong. In the portrait of the Jeokgae wearing a Yebok HeukDanryung, in the case of the Samo, the height of the Samo, which had been raised at the beginning of King Seongjong, was lowered again, and the parietal part was rounded. The pattern was not expressed on the wide oval side wings of the Samo. In addition, the pattern was not expressed on the acheongsaek Danryung, Dapho, and Cheolrik. The colors of Dapho and Cheolrik were unified in green and red, respectively. The Mu of Danryung and Dapho was expressed as 'in and out wrinkled Mu', and the shoes were expressed in Baekhwa. Another feature is that the Jeokgae's portrait is expressed not as the Pumgye at the time of appointment, but as the Pumgye of the portrait production time. In the portrait of the Jeongguk·Jeongnan wearing a Sibok HeukDanryung, the height of the Samo lowered from the Jeokgae was maintained, while the parietal part was slightly narrowed and bent forward. The side wings of the Samo were expressed as an oval with a uniform width, and still the pattern was not expressed on the side wings. The pattern was not expressed in the costume of the Danghagwan's portrait, but the cloud pattern began to be expressed in the costume of the Dangsanggwan's portrait. And the Danryung was expressed as single Danryung without lining. In the portrait of Dangsang, the red Dapho and green Cheolrik were expressed, and in the portrait of Dangha, the green Dapho and blue Cheolrik were expressed. Therefore, it was found that the color of the undergarment was distinguished according to the Dangsang and Dangha. In Danryung and Dapho, the 'in and out wrinkled Mu' were maintained. The shoes were expressed in Heukhwa, and the rank badge and rank belt reflect the Pumgye at the time of the appointment. On the other hand, the portrait of Wisa could not be confirmed, but through the recording painting of the reign of King Meongjong, it was found that it was similar to the Danryung system of the reign of King Jungjong. Through the 2^nd period of the meritorious vassal's portrait of Jeokgae, it was confirmed that the HeukDanryung outfit began to be used as the official uniform of the meritorious vassal's portrait, and that the Pumgye of the portrait production time was reflected in the portrait. After the meritorious vassal's portrait of Jeongguk, the pattern began to be expressed in the costumes, and in particular, it was possible to distinguish Dasang and Dangha by the presence or absence of the HeukDanryung's pattern. In addition, it was confirmed that the expressed aspect of the official uniform was consistent with the practices and regulations at the time.

This is a study on angels' costumes in religious paintings, especially as this relates to the questions of concepts and theological symbolism. Angels, as spiritual creatures in Christian thought, play the role of praising God's glory, as messengers of God, the role of guarding Israel and the Church, and protecting or punishing human beings. Sometimes the angels appear in incarnate form. They display no sexual differences and are not able to procreate. The angels' funtional classification being thus; nevertheless, they are pictured in various costumes and appearances according to characteristics of the paintings. The angel Michael appears as a man of dignity when pictured as a guard; the angel Gabriel in the annunciation is often portrayed as a woman of mystical beauty. Under the Renaissance, the mighty cherubim and seraphim at Yahweh's throne are degraded as plump child-angels, or winged child-heads looking alike Eros or Cupid. They have become playful and all too obviously non-heavenly chrubs, accepted features of the Temple decorations. However, cherubim are often depicted as naked or wrapped around with a piece of cloth and accompanied with wind, which symbolizes the Glory of God. The angels, costumes without seam are hung over or wrapped around the body, and when sewn they are simple and ample enough that they fall in a great many folds. However, by the 14C. angels are mostly dressed in costumes common to all Europe, and after that angels gradually appear in folk costumes; for example Italian, Flemish, etc. Dalmatic, the typical costume of Byzantine often shows up as angels' dresses even after the period. Originally the dalmatic was the Roman tunic to which Eastern influences added. The Roman clavus on the tunic had gradually lost distinction until, by the Imperial epoch, it was worn by the lowest servants. It was proudly therefore, as 'The servants of God', that the early Christians are shown wearing the clavus on their wide, ungirdled, sleeved dalmatics. In addition to their costume, angels have some other distinct charateristics. First, angels have a halo around their head; this symbolizes their holiness. Second, angels wear a narrow diadem or a queen's crown that seems to denote their glorious status close to God's throne. Third, the cloth band across the breast resembles a priest's stole, which suggests the sacred role of a priest and symbolizes the grace santified. Fourth, lilies in the annunciations are symbols of Mary's virginity. chastity, innocence and heavenly bliss. Angels hold palms or olives in their hands. The former denote prosperity. beauty and the Christians' reward after death; the latter represent peace and amity. the imperial crown made of olives means victory. Fifth, angels in paintings always have a pair of wings, which can be traced to scripture where cherubim and seraphim are described as having pairs of wings. Angels' wings often have colors of the rainbow, and the rainbow is compared to God's glory. Sixth, generally artists paint angels' costumes as white, blue, green, gold and purple. Other colors such as red rarely appear. According, to scriptures it is believed that angels should be depicted 'as white as snow'. According to the biblical expressions of angels as lightning, sun or a pillar of fire, angels should be described as creatures of light. Nevertheless being a form of art, religious paintings may differ in their presentation according to an artist's inspiration and intention. Since religious paintings illustrated above were almost all done before the Reformation, symbols of colors used in the Catholic Church will also be mentioned. The white color symbolizes chastity, purity, brightness, delight and divinity. Green represents new birth, eternal life, spiritual revival and the expectance of the grace of God. Blue, the color of sapphires, denotes chastity and truth. Red, the color of rubies, represents divinity, love and religious passion. Violet is the color of dignity, indicating the sovereign, royal or imperial power and the great Sacrifice of Christ. As mentionad above, angels' costumes were expressed in accordance with contemporary patterns or as indicated in the Bible, and accesories and colors correspond with Christian symbols. Therefore these facts should be taken into consideration when it comes to the study of costume history.

The borehole radar methods used to tunnel detection are mainly classified into borehole radar reflection, directional antenna, crosshole scanning, and radar tomography methods. In this study, we have investigated the feasibility and limitation of each method to tunnel detection through case studies. In the borehole radar reflection data, there were much more clear diffraction signals of the upper wings than lower wings of the hyperbolas reflected from the tunnel, and their upper and lower wings were spreaded out to more than 10m higher and lower traces from the peaks of the hyperbolas. As the ratio of borehole diameter to antenna length increases, the ringing gets stronger on the data due to the increase in the impedance mismatching between antennas and water in the boreholes. It is also found that the reflection signals from the tunnel could be enhanced using the optimal offset distance between transmitter and receiver antennas. Nevertheless, the borehole radar reflection data could not provide directional information of the reflectors in the subsurface. Direction finding antenna system had a advantage to take a three dimensional location of a tunnel with only one borehole survey even though the cost is still very high and it required very high expertise. The data from crosshole scanning could be a good indicator for tunnel detection and it could give more reliable result when the borehole radar reflection survey is carried out together. The images of the subsurface also can be reconstructed using travel time tomography which could provide the physical property of the medium and would be effective for imaging the underground structure such as tunnels. Based on the results described above, we suggest a cost-effective field procedure for detection of a tunnel using borehole radar techniques; borehole radar reflection survey using dipole antenna can firstly be applied to pick up anomalous regions within the borehole, and crosshole scanning or reflection survey using directional antenna can then be applied only to the anomalous regions to detect the tunnel.

In this study, the period before the Gwanbok of meritorious vassals' portraits was expressed in the acheongsaek-Heuk-Danryung was defined as the first period, and the costumes worn in portraits of meritorious vassals from Gaeguk (1392) in the early Joseon Dynasty to Jwali (1471) during the era of King Seongjong were reviewed. The portraits(1476) of Jeokgae meritorious vassals (1467) depicted as the Gwanbok of acheongsaek Heuk-Danryung were excluded. Among the copies that are currently considered to be portraits of meritorious vassals belonging to the first period, the portraits of Lee-je, Lee Cheon-woo, Ma Cheon-mok, Shin Suk-ju, Seol Gye-jo, and Lee Sung-won were selected, and the formative characteristics of Gwanbok components were examined. The Samo of Sam-Gongsin in the early Joseon Dynasty had a low height, a rounded end, and the side wings were narrow and short. However, since King Danjong, Jeongnan·Jwali meritorious vassals retained a higher form, and the side wings were twice as long. It was also confirmed that the pattern was not expressed in the side wings. The Danryung was expressed in light-colored Danryung without specific colors at the beginning of the country. After King Sejong, the Heuk-Danryung system for Yebok began, but it was not reflected in the Gwanbok of meritorious vassals' portraits, and was expressed as damhongsaek-Danryung after King Danjong. The pattern was not expressed on the exterior of the Danryung, and inner-wrinkled Mu was expressed on the side line. The Dapho and Cheolrik, the undergarments of the Danryung, were also confirmed as being blue (the Dapho) and green (the Cheolrik) after the Jeongnan meritorious vassals. The early Sam-Gongsin's Pumgye was expressed by rank belt, but as the system of rank badge was established after King Danjong, it began to express the Pumgye by rank badge and rank belt. Among the portraits of meritorious vassals, the rank badge was expressed only in the portrait of Sin Suk-ju, a Jeongnan meritorious vassal. As Hwaja worn on the Danryung, Heuk-hwa were confirmed in the Sam-Gongsin portraits of the early Joseon Dynasty. However, in the portraits of Jeongnan and Jwali meritorious vassals after King Danjong, the Baek-hwa was confirmed. In addition, in the seam parts of the Heuk-hwa and Baek-hwa identified in some portraits of meritorious vassals, Hwi decorated with yeongeumsa were identified, and it was found that the Hwaja decorated with Hwi were the Hyeopgeum-hwa worn by the 3rd rank and above.

In this study, we divided the portraits in the reign of King Seonjo into those which were created before and after the Japanese invasion. We then examined various aspect of costumes expressed in the portraits of meritorious vassals. To analyze official uniforms (Heuk-Danryeung), we examined the Samo height; the side wings' type and pattern; the Danryeung pattern; the Mu style; the processing method of lateral lines in Danryeung the rank badge and rank belt, the color of Dabho and Cheolrik, which were undergarment of Danryeung and Heuk-wa. The meritorious vassals' portraits, prior to Imran, were analyzed with a portrait of Han Eung-in, a Gwang-kuk Pyeong-nan meritorious vassals. The Samo was the highest of the Choson dynasties, and the cloud and treasure pattern was identified on the side wings. The Heuk-Danryeung was a dark blue(acheongsaeg) Danryeung of manja-shaped cloud patterns with a large outward wrinkled Mu, and it had a wild goose badge (second rank) and a Sabgeumdae. It did not coincide with the Pumgye(Jaheondaebu) recorded in Gugjo-inmulgo. Reddish Dabho for Dangsang-kwan, green Cheolrik which was undergarment of Danryeung, and Heuk-wa. were identified. After the invasion of Japan, portraits of Hoseong, Seonmu, and Cheong-nan meritorious vassals were analyzed through eighteen portraits, including Lee Hyeon-bok. After the invasion of the Japanese, the height of the Samo's top was much lower and the width of the side wings was wider than before the invasion of Japanese. The Heuk-Danryeung was a dark blue (acheongsaeg) Danryeung of manja-shaped cloud patterns with a stretching backward Mu. Rank badge and rank belts were almost identical with the record, but there were two exceptions (Sin-jab and Kim, Sae-sin). Therefore, it was reaffirmed that the meritorious vassals' portraits were drawn by the Pumgye at the time of appointment. Among the undergarments of Heuk-Danryeung, green Dabho(11), blue Dabho(4), reddish Dabho(3), and blue Cheolrik(10), green Cheolrik(6), reddish Cheolrik(1), and yucheongsaeg Cheolrik(1) were identified, However, it is suggested that the Dabho of Hoseong, Seonmu, and Cheong-nan meritorious vassals should be the reddish Dabho of Dangsang-kwan, which is the same as the previous Imran, and a green Cheolrik.

The purpose of this study was to obtain information about the type of drones suitable for the management of entrants and entrants of islands in the marine national park. The research sites were 25 islands in the Hallyeohaesang National Park. The target islands were divided into three zones, and were investigated with different types of drones. The survey period was from October to November, 2019. As a result of the operation of drone airframe, drone with fixed wings was found to be favorable for the management of marine parks in medium and long distances compared to other types, but stopping flights for broadcasting was found to be unsuitable. Drone with rotational wings was found to be suitable for image acquisition and broadcasting through close flight. However, it was deemed suitable for short and medium distance flights because of the fast battery consumption. In the case of helicopter rotorcraft drone, image acquisition and broadcasting were possible, but noise and vibration caused by propellers were disadvantageous. The number of entrants to the islands totaled 410 and the main act was fishing. The proportion of entrants to the islands in Area A was higher than that of other areas, and thus it was deemed more necessary to manage the area. Broadcasting was found to have had a positive effect on the management of fishers.

The behavior and circadian rhythm of emergence, copulation and oviposition in the Oriental tobacco budworm (Heliothis assulta Guenee) were studied to obtain the following results. More than three quarters of adults emerged within 3 hours after the light-off. It took about 33 min for an adult to expand and tan its wings after emergence. Adult male showed a sequential pattern of mating behavior, such as antennal movement, wing elevation and vibration, exten¬sion of hairpencils, and tapping of female ovipositor leading to a copulation. However, adult female revealed a rather simple behavior, such as protraction and retraction of her terminal abdomen and vibration of wings. All of the mating took place during the early part of the scotophase, with the peak from 1 hr to 2 hrs after the light-off. But the mating peak in virgin females tended to advance with age. Adult females showed the highest rate of mating among 24 hr-olds and the rate declined with age. The rate of first matings in males gave a very similar pattern to that of females. The duration of copulation was $77\pm$14min. Oviposition occurred throughout the entire scotophase, with the peak during the first 2 hrs. The most nu¬mber of eggs deposited daily was seen on the 3rd day after the mating. Mating rate, number of eggs laid and longevity we~e compared under different sex ratio. Unmated adults lived longer than mated adults.

This study were examined for their external morphological characters such as root, leaf, inflorescenses, flower, stamen, pistil, and fruit as to Korean Thalictrum L. and discussed taxanomic value of characters, and made out a new key. This study confirmed that specialized stems and roots type were divided into fibrous type, fibrous having a tuber type, long fusiform tuberous type, tuberoid type, rhizome type and stolon type. The stem were divided into two types based on existence and nonexistence of striate or pubescent. Leaves were usually 2-3-ternately and was divided into three types based on leaf apex, leaf base and number of lobe. Inflorescenses were divided into two type; corymb, panicle. Flower is bisexual, and don't have petal. It was divided from existence and nonexistence of calyx when it flowering. Especially, the stamens were divided from anther shape and apex shape, degree of dilation of filament, epidermic shape of filament etc., and the pistils were divided from glandular on ovary, length of carpel stipe etc.. The fruit is a achene and it was divided from achene shape, achene rib or wings, achene stipe length. This study suggest that useful characters for identifying section are degree of dilation of filament, anther shape, achene rib and wings, degree of dilation of achene. Also, roots, leaf shape, stamen and pistil shape, achene beak and achene length, achene and leaf hair appear to be useful characters for identifying species.

Objectives This study was aimed to find the significant features of face form according to the Taeeumin and Soyangin by analyzing the three-dimensional face information data. Also, making standard face of the Taeeumin and Soyangin was an object of this study. Methods We collected three-dimensional face data of patients aged between 20~45 years old diagnosed by a specialist of Sasang constitutional medicine. The data were collected using a 3D scanner, Morpheus 3D(Morpheus Corporation, KOREA). Extracting a face feature point total of 64, was set to 332 pieces(height, angle, ratio, etc.) of each variable between feature points. ANOVA test were used to compare the characteristics of subjects according to the Taeeumin and Soyangin. Results When not to consider gender, the Taeeumin and Soyangin were different from the 18 items(3 items in the ear, 9 items in the eye, 1 item in the nose, 1 item in the mouth, 4 items in the jaw). When to consider gender, the Taeeumin and Soyangin men were different from the 6 items(1 item in the ear, 2 items in the nose, 3 items in the face). And the Taeeumin and Soyangin women were different from 17 items(1 item in the ear, 10 items in the eye, 2 items in the nose, 1 item in the mouth, 3 items in the face). Conclusions These results show Taeeumin's face(both men and women) width of the right and left is larger than the length of the top and bottom. Compared to men of Soyangin, men of Taeeumin has greater wings of the nose. Compared to women of Soyangin, women of Taeeumin has longer length of the eye. Soyangin's face(both men and women) length of the top and bottom is larger than the width of the right and left. Compared to men of Taeeumin, men of Soyangin has smaller wings of the nose. Compared to women of Taeeumin, women of Soyangin has more stereoscopic facial features at the top and bottom of the lateral face. Also, by accumulating three-dimensional face data, this study modeled the standard facial features by Taeeumin and Soyangin. These results may be helpful in the development of Sasang constitutional diagnostics utilizing the characteristics of the facial form at later.

The characteristics of Doppler shifts in a quiet region of the Sun are investigated by comparing between the $H{\alpha}$ line and the Caii infrared line at 854.2 nm. A small area of $16^{\prime\prime}{\times}40^{\prime\prime}$ was observed for about half an hour with the Fast Imaging Solar Spectrograph (FISS) of the 1.6 meter New Solar Telescope (NST) at Big Bear Solar Observatory. The observed area contains a network region and an internetwork region, and identified in the network region are $H{\alpha}$ fibrils, Caii fibrils and bright points. We infer the Doppler velocity from each line profile at a point with the lambdameter method as a function of half wavelength separation ${\Delta}{\lambda}$. It is confirmed that the bisector of the spatially-averaged Caii line profile has an inverse C-shape of with a significant peak redshift of +1.8 km/s. In contrast, the bisector of the spatially-averaged $H{\alpha}$ line profile has a different shape; it is almost vertically straight or, if not, has a C-shape with a small peak blueshift of -0.5 km/s. In both the lines, the bisectors of bright network points are much different from those of other features in that they are significantly redshifted not only at the line centers, but also at the wings. We also find that the spatio-temporal fluctuation of Doppler shift inferred from the Caii line is correlated with those of the $H{\alpha}$ line. The strongest correlation occurs in the internework region, and when the inner wings rather than the line centers are used to determine Doppler shift. In this region, the RMS value of Doppler shift fluctuation is the largest at the line center, and monotonically decreases with ${\Delta}{\lambda}$. We discuss the physical implications of our results on the formation of the $H{\alpha}$ line and Caii 854.2 nm line in the quiet region chromosphere.
