Seojangdaeyajodo is a drawing of military night training on February 12th (lunar leap month), 1795. Focusing on the Seojangdaeyajodo, the characteristics and of the costumes worn by various types of officials were examined. There were 34 officials located near King Jeongjo in and around Seojangdae, with 27 Dangsanggwan and 7 Danghagwan. They wore three types of costumes, including armor, yungbok, and military uniforms. All of the twelve armor wearers and the five officials wearing yungbok were dangsanggwan, and the military uniform wearers included eleven dangsanggwan and six danghagwan. For the shape of the armor, the armor relics of General Yeoban, suitable for riding horses, and the armor painting of Muyedobotongji were referenced, and the composition of the armor was based on practicality. The armor consists of a helmet, a suit of armor, a neck guard, armpit guards, arm guards, and a crotch guard. The color of the armor was red and green, which are the most frequently used colors in Seojangdaeyajodo. The composition of yungbok was jurip, navy cheollik, red gwangdahoe, socks made of leather, and suhwaja. The composition of the military uniform was a lined jeolrip, dongdari, jeonbok, yodae, jeondae, and suhwaja. There were differences in the fabrics used in dangsanggwan and danghagwan military uniforms. Dangsanggwan used fabric with depictions of clouds and jewels, and danghagwan used unpatterned fabric. Moreover, jade, gold, and silver were used for detailed ornamental materials in dangsanggwan. The weapons included bows and a bow case, a sword, a rattan stick, wrist straps, and a ggakji. In the records of the King Jeongjo period, various colored heopsu were mentioned; the colors of the dongdari and jeonbok of dangsanggwan and danghagwan were referenced in various colors. It was presented as an illustration of costumes that could be used to produce objects accurately reflecting the above historical results. The basic principle of the illustration was to present the modeling standards for 3D content production. Samples of form, color, and material of the corresponding times and statuses were presented. The front, the side, and the back of each costume and its accessories were presented, and the colors were presented in RGB and CMYK.

The results of study on the meaning landscape and environmental design techniques of the Byulup, Yoohoedang garden(Hageowon) based on the story in the collection of Kwon Yi-jin (Yoohoedangjip, 有懷堂集), are as below. First, Yoohoedang Kwon Yi-jin (有懷堂 權以鎭 : 1668~1734) constructed a Byulup garden consisting of ancestor grave, Byulup, garden, and a school, through 3 steps for 20 years in the back hill area of Moosoo-dong village, south of Mountain Bomun in Daejeon. In other words, he built the Byulup(別業, Yoohoedang) by placing his father's grave in the back hill of the village, and then constructed Yoegeongam(餘慶菴) and Geoupjae(居業齋) for protection of the pond(Napoji, 納汚池), garden(Banhwanwon, 盤桓園), and ancestor graves, and descendants' studying in the middle stage. He built an extension in Yoohoedang and finally completed the large-size garden (Hageowon) by extending the east area. Second, in terms of geomancy sense, Yoohoedang Byulup located in Moosoo-dong village area is the representative example including all space elements such as main living house (the head family house of Andong Kwon family), Byulup (Yoohoedang), ancestor graves, Hagoewon (garden) and Yoegeongam (cemetery management and school) which byulup type Byulseo should be equipped with. Thirdly, there are various meaning landscape elements combining the value system of Confucianism, Buddhism and Taoism value, including; (1) remembering parents, (2) harmonious family, (3) integrity, (4) virtue, (5) noble personality, (6) good luck, (7) hermit life, (8) family prosperity and learning development, (9) grace from ancestors, (10) fairyland, (11) guarding ancestor graves, and (12) living ever-young. Fourth, after he arranged ancestor graveyard in the back of the village, he used surrounding natural landscapes to construct Hagoewon garden with water garden consisting of 4 mountain streams and 3 ponds for 13 years, and finally completed a beautiful fairyland with 5 platforms, 3 bamboo forests, as well as the Seokgasan(石假山, artificial hill). Fifth, he adopted landscape plantation (28 kinds; pine, maple, royal azalea, azalea, persimmon tree, bamboo, willow, pomegranate tree, rose, chinensis, chaenomeles speciosa, Japanese azalea, peach tree, lotus, chrysanthemum, peony, and Paeonia suffruticosa, etc.) to apply romance from poetic affection, symbol and ideal from personification, as well as plantation plan considering seasonal landscapes. Landscape rocks were used by intact use of natural rocks, connecting with water elements, garden ornament method using Seokyeonji and flower steps, and mountain Seokga method showing the essence of landscape meanings. In addition, waterscape are characterized by active use of water considering natural streams and physio-graphic condition (eastern valley), ecological corridor role that rhythmically connects each space of the garden and waterways following routes, landscape meaning introduction connecting 'gaining knowledge by the study of things' values including Hwalsoodam(活水潭, pond), Mongjeong(蒙井, spring), Hosoo(濠水, stream), and Boksoo(?水, stream), and sensuous experience space construction with auditory and visualization using properties of landscape matters.

본 연구는 7~10월에 백색 꽃이 개화하는 화훼류인 너도개미자리[Minuartia laricina (L.) Mattf.]를 지피용 관상식물로 활용하기 위한 재배방법을 개발하기 위하여 수행되었다. 유용식물증식센터에서 종자를 분양 받아 2019년 4월 19일에 트레이에 파종하여 충북대학교 유리온실에서 육묘한 유묘를 7월 4일에 정식하여 실험재료로 사용하였으며, 9월 24일까지 약 11주 동안 재배하였다. 식재 용기에 따른 너도개미자리의 생육을 알아보기 위하여 비닐 포트 2, 3, 4치를 이용하였다. 토양 실험은 단용토로 원예상토를 사용하였으며, 혼용토는 마사토와 중화 피트모스를 2:1, 3:1 비율로 혼합한 후 토양 9L당 퇴비 1L를 첨가하였다. 묘 소질에 관한 실험은 파종립수(1, 2, 4, 6립)와 파종용기(162, 200, 288구 트레이)를 각기 달리하여 육묘한 유묘를 정식한 후 생육을 비교하였다. 대조구는 비닐 포트 3치에 원예상토를 충진하고, 200구 트레이에 1립씩 파종하여 생산된 1셀을 정식하였다. 연구의 결과, 식재 용기에 따른 너도개미자리의 생육은 4치 비닐 포트에서 가장 효과적이었다. 그러나 경제적 측면을 고려하면, 개화율이 양호하였던 3치 포트를 이용하는 것도 고려해볼만한 것으로 판단된다. 토양 종류별로는 원예상토에서 생육이 가장 양호하였다. 그러나 너도개미자리는 배수가 잘되는 산지에 자생하는 것으로 알려져 있어, 생육이 비교적 양호한 결과를 보인 마사토와 피트모스를 3:1로 혼합한 토양에서 재배하는 것도 이용가치가 높을 것으로 생각된다. 파종 립수에 따른 너도개미자리의 개체당 생육은 셀당 파종된 립수가 적을수록 왕성하였으며, 1립과 2립 파종묘가 우수하였다. 2립 파종묘의 포트당 생체중이 가장 무거운 결과를 보였으며, 4립과 6립 파종묘는 개체당 생육이 크게 억제되어 2립 파종묘에 비해 저조하였다. 파종 용기에 따른 생육은 육묘에 사용된 용기의 크기가 클수록 정식 후 모든 생육이 왕성하였으며, 162구에서 생산한 묘가 가장 우수하였다. 한편 개화율은 200구 생산 묘가 가장 높았으며, 생육이 가장 왕성하였던 162구 생산 묘는 왕성한 생육으로 인해 개화가 비교적 지연되는 경향이었다. 결론적으로 너도개미자리의 재배는 4치 비닐 포트에 원예상토를 충진하여 200구 트레이에 셀당 2립 파종하여 생산된 유묘를 정식하는 것이 지피용 재배에 가장 효과적인 것으로 생각된다. 경제적인 측면을 고려할 때 3치 비닐 포트에 마사토와 피트모스를 3:1로 혼합한 토양을 이용하는 것도 효율적일 것으로 생각된다.

The tail portion of dried 6-year old white ginseng was extracted and sugars and nitrogen compounds were also evaluated for chemical properties depending on varying conditions of extractions. The factors studied were extraction temperature in the range of 70-$100^{\circ}C$, ethanol concentration of 0-90% and the times of extractions which was taken 8 hours per each extraction in water at $80^{\circ}C$. For the effect of ethanol concentration in the extraction solvent, it was found that the amounts of free, reducing and total sugars and starch recovered in extract were almost linearly decreased along with the increase of concentration and the nonprotein nitrogen accounted over 84% of total nitrogen in extract. As ethanol concentration became increased, extractions of total nitrogen and water souluble nonprotein nitrogen were decreased especially in 90% ethanol. For the extraction temperature, all the sugar fractions with water and 70% ethanol except free sugar have tended to increase along with the temperature raised from 70 to $100^{\circ}C$ and it was found there is little changes of nitrogen compounds in the temperature range except a rapidly increase in water soulble protein at $100^{\circ}C$. For the times of extractions, showed that most of extractable compounds were extracted in 3 times of extractions with water at $80^{\circ}C$. It was shown that more than 95f) of sugars and 80% of nitrogen compounds were yielded with water extraction. Accordingly it was efficient to extract with water or 70% ethanol in 3 times in terms of !actor and energy consumption.

This study was conducted to know the change pattern of chemical components, especially proximate constituents, saponin and free sugars in roots of 4-year ginseng according to different harvesting time, and to find out the optimum harvesting time on the basis of chemical components in fourth year ginseng root. The crude protein content was 20.77% of the highest on the April (shootinzg stage),13.13% of the lowest on the June among all growing stages, and was constant at 17% after the August. But crude oil and fiber contents showed the highest value on the May (flowering stage). The content of total sugars which was the largest constituent among the chemical components in ginseng root was in the range of 60~7(1% during the all growing stages. It showed the highest value of 7l% on the June, but the lowest of 60% on the May. The total free sugar contents was the highest on the April (20.40%), but the lowest on the May (11.89%). The change pattern of sucrose contents (10.96-19.60%) was same as the total sugars contents (11.89-20.40%), on the other hand, the contents of glucose and maltose were not changed significantly during all harvesting times. The contents of crude saponins and total ginsenosides had the value of 7.60% and 4.09% on the May, respectively. That was statistically significant, but the other harvesting times were not. Therefore, on the basis of the only chemical characteristics in the four year-old ginseng root, we suggest that the harvesting on the May at flowering stage was most proper time.

As information and information technology become more important in competitive corporate environments, the risk of information security breaches has increased accordingly. Although organizations establish security measures to manage information security risks, members of organizations do not comply with them well, and their information security behavior intention is unclear. Therefore, to understand the information security risk management intention of the members of organizations, the present study developed a research model using Protection Motivation Theory, Supervisory Authority Pressure, and Background factors. This study presents empirical research findings based on the analysis of survey data from 201 members of financial institutions. Perceived Severity, Self-efficacy, and Supervisory Authority Pressure had a positive effect on intention; however, Perceived Vulnerability and Response Efficacy did not affect intention. Security Avoidance Habit, which was considered a background factor, had a negative effect on all parameters, and did not have an effect on intention. Security Awareness Training, another background factor, had a positive effect on information security risk management intention and perceived vulnerability, self-efficacy, response efficacy, and supervisory authority pressure, and had no effect on perceived severity. This study used supervisory authority pressure and background factors in the field of information security, and provided a basis to use supervisory authority pressure in future studies on behavior of organizations and members of an organization. In addition, the use of various background factors presented the groundwork for the expansion of protection motivation theory. Furthermore, practitioners can use the study findings as a foundation for organization's security activities, and to improve regulations.

The effect of blueberries on the quality characteristics of strawberry jam substituted with 50% sugar, glucose syrup 10% was investigated. Strawberry jams with 5, 10 and 20% blueberries in place of strawberry were prepared and evaluated for moisture content, reducing sugar, total acidity, pH, color, total sugar (°Brix), pectin content, anthocyanin content, DPPH radical scavenging activity, texture analysis and sensory characteristics. As the amount of blueberries increased, total acidity, °Brix , reducing sugar content and anthocyanin content of jams increased, while pH decreased, moisture content has changed little. The DPPH radical scavenging activities of the 80% methanol extract from jams were 75.33%, 85.75%, 91.23% and 92.73% at a concentration of 8 mg/mL. Radical scavenging activity increased with the added concentration of blueberries. The lightness decreased with addition of blueberries, but the redness and yellowness increased. The sensory scores for jams increased with the increase of blueberry content; however, strawberry jams with 10% blueberries showed the best scores.

Level of Service(LOS) is classified A through F in highway system (KHCM), usually using LOS C in express way and D in national road. (LOS C denotes 75% of capacity) Meanwhile in Railroad System, there is no clearly defined LOS, and the daily demand in infra-structure planning has been used. It is very important that LOS provides consequently a consensus of opinion between users and operators because there is a close relation between user demand and level of services. Considering this, there should exist clearly defined Level of Services in Railroad System Planning so that demand can be predicted precisely.

The effects of extract mixture of red ginseng and steamed Rehmaniae radix prepared for antidiabetic activity was examined in streptozotocin-Induced diabetic rats. The increased blood glucosec level in the streptozotocin-induced diabetic rats was significantly decreased by the treatment with the mixture (800, 1600 mg/kg, p.o.). However, neither red ginseng extract nor steamed Rehmaniae radix extract alone showed significant hypoglycemic effects. The mixture prevented a weight loss in streptozotocin-induced diabetic rats. These results suggest that the mixture has the relieving action against streptozotocin-induced hyperglycemia.
