Hanging boards of the Joseon royal court are hung on buildings related to the royal family, such as palaces and Jongmyo Shrine, to show the hierarchy and character of the building. In addition, the manufacturing method and materials are recorded in the royal protocols of the Joseon Dynasty, so it is an important material for studying the manufacturing method and material changes at that time. However, the hanging boards were restored several times due to fire or war, and it is presumed that there is a change in the original form and material of the hanging boards. In particular, many hanging boards of the Joseon royal court were written with calligraphy by kings, so there are many forms consisting of gold letters on a black background. This study tried to analyze the pigments remaining in the letters of 44 of the Joseon royal hanging boards, which are presumed to be gold letters, and to find out the changes in the hanging board production method and materials by referring to the analysis results. The letters of the hanging boards studied were classified according to the current state of the gold pigment and the detected components. As a result of the analysis of character pigments, 24 embossing techniques and 5 intaglio techniques were mainly detected with gold (Au), but 15 embossing techniques were detected with brass (Cu, Zn). Only blue-green substances, not gold pigments, remain in some of the hanging boards in which brass components were detected. A reproduction experiment was conducted because the pigments of the brass component were not recorded in the literature and were not currently used as Dancheong pigments. In the reproduction experiment, it was difficult to confirm the application and use of brass pigments due to the limitations of materials, but it is judged that research on the timing and method of using brass pigments is needed in the future.

In early Highlighting the client's personality especially, home design demands very careful consideration. It's not an easy task to understand the characteristics of each family member, to take into account their requirements, and strike proper harmony among them. For this Sampung Apartment Project, I decided to create a cozy homelike atmosphere by using overall modern and antique furniture, props, and lighting. I tried a different sense of space by choosing wood as the main material, installing furniture that looked antique, and applying painting with touch instead of pictures or wallpaper By the use of the light bulb color overall, lighting was yellow and added more comfort. Local lighting was used in certain places to add more fun along with the props. After choosing white as the main color, point colors were determined according to the client's inclination toward green and blue. The color choice also matched the client's paintings that were in soft green and blue. Each room was planned and color coordinated according to their own characteristics. The children's rooms were planned with such point colors as pink, green, and blue. The master bedroom and the family room were produced around gold and grey color, respectively.

농산물 수확 이후 저장 유통 과정에서 일어나는 생리적 현상 변화에 따른 내부품질의 측정 분석연구가 활발히 진행되고 있다. 이 연구에서는 비파괴 측정 방법들 중 하나인 자기공명영상(Magnetic Resonance Imaging, MRI) 기술을 활용하여 후숙 과일인 키위의 저장 일수에 따른 형태 및 내부 구조의 변화를 조사하였다. 공시재료는 국내에서 판매되고 있는 키위들 중 3품종(뉴질랜드산 Sun Gold, 뉴질랜드산 Green, 칠레산 Jin Green)별로 균일한 크기의 과일 5개씩을 이용하였으며, 시료를 실험실내($16.6^{\circ}C$, 38% RH)에서 18~19 일간 보관하면서 3~5일 간격으로 5회 시험하였다. 전북대 농업과학기술연구소가 보유하고 있는 MRI(M10, Aspect Imaging, Israel)를 활용하여 영상 이미지를 얻었으며, 저장 기간에 따른 무게 감소는 전자저울(한성, HK-series)을 이용하였다. 자기공명영상 이미지는 Gradient-Eco 펄스열을 사용하였고, 횡단면(Axial)의 영상면(Image-direction)을 중심으로 영상영역(Field of View, FOV)은 $80mm{\times}80mm$로 1회 촬영 할 때 마다 30개의 영상들을 얻었다. 저장 기간이 길어질수록 내부 공동현상이 커지는 것으로 나타났고, 뉴질랜드산 Sun Gold 품종은 다른 두 품종보다 내부 공동이 빠르게 나타났다. 실험이 끝나는 날에는 껍질이 연화되어 타원형의 형체를 계속 유지하지 못하고 붕괴되는 이미지를 MRI를 통해서 관찰 할 수 있었다. 시간이 지남에 따라 영상들의 위치가 일정하지 않고 일부 회전을 한 것처럼 나타났다. 이는 키위 전용 홀더를 만들어 고정하지 않고 측정하다보니 생긴 오차로 생각 되었다. 키위를 건조한 공간에 오래 보관하였기 때문에 시간이 지남에 따라 수분증발과 연화된 껍질 사이로 과육이 흘러 일부를 제외한 대부분의 키위 무게가 일정하게 감소하는 것을 알 수 있었다.

According to oral tradition, the King Sejo's palanquin is indeed the palanquin of King Sejo, the 7^th monarch of the Joseon dynasty who reigned from 1455 to 1468, which was left behind after visiting the Magoksa temple. The palanquin is painted in five colors, mainly black, white, yellow, red and green. The chromaticity measurement of the yellow pigment showed that orpiment and gold are a noticeable distinction between the lightness and b^⁎ values. In the case of the red pigment, a^⁎ values of areas painted with cinnabar tend to measure at high values. As a result of the optical microscopy, scanning electron microscopy and energy dispersive spectroscopy analyses, it was determined that Chinese ink was used for the black pigment, lead white and white clay were used for the white, and orpiment and gold for the yellow. The red pigment was found to be the result of minium, cinnabar and red ocher, atacamite was used as green pigment. Though the analysis results of the cross sections on very small exfoliation fragments of pigments, it was confirmed that white clay and lead white were used for the preparation layer. In addition, several coloration techniques were considered based on these analyses.

This study aims to examine associationistic psychology and psychological operation associated with each color image, then to study the relation between particular colors used in paintings produced by Gogh and Klimt in different times and these painters' psychology in a bid to explore the meaning and role of psychological operation of colors. The findings of the study indicated that red and blue colors represent mainly negative images, while yellow and orange colors represent mainly positive images and psychologies. Specifically, in the case of Gogh, red expresses anxiety, a negative image, yellow symbolizes passion, a major positive image of emotional liberation, dark and thick green and the green involving blue symbolize negative images, emptiness and despair, and blue represents negative images of internal desire conflicts, and screaming. Also, purple used together with white represents anxiety and depression. In the case of Klimt, red represents negative images of anger toward mother and suppressed energy, yellow, an alternative to gold color, symbolizes the positive image of hope, passion, desire and eroticism, the arrangement of strong gold and orange colors represents a color of psychological healing more than a color of hope. As such, colors used in paintings produced by modern Western painters express the physiological conditions, psychological feeling and emotion in life, at the time when the artists produced such works. It was found that colors are yet another language of expressing emotions, and symbolize the psychologies of the artists, indicating that colors have something to do with the painters' experience and emotional impulses.

This purpose of this study was to determine the best enrichment medium for rejuvenating and recovering Salmonella placed in cold temperature prior to the employment of the gold biosensor combined with a light microscopic imaging system. A mixture of nalidixic-resistant Salmonella Typhimurium and Enteritidis were inoculated onto chicken (1,000 CFU/chicken). After cold injury at $4^{\circ}C$ for 24 hr, Salmonella on chicken was enriched for 6 hr with six non-selective media including buffered peptone water broth, lactose broth, brain heart infusion broth (BHI), universal pre-enrichment broth, nutrient broth, and tryptic soy broth, and five selective media including brilliant green broth (BG), rappaport-vassiliadis R10 broth, selenite cystine broth, selenite broth, and tetrathionate brilliant green broth (TBG) for the comparison of Salmonella growth. Various concentrations of Salmonella (10, 50, 100, 500, and 1,000 CFU/chicken) were then enriched for 6 hr in both BHI and BG media to select the best media. BHI was selected as the most effective non-selective enrichment medium, while BG was selected as the most effective selective enrichment medium. Finally, BHI medium was selected as the most efficient enrichment medium for Salmonella growth injured from cold temperature during processing or storage.

Objective: Although pork loins is not a tough meat, they need to develop meat products with a soft texture for the elderly. This study focused on the physicochemical properties and tenderness characteristics of pork loin injected with green kiwifruit juice (GRJ) and gold kiwifruit juice (GOJ) during various incubation times. In addition, the antioxidant activities of hydrolysate derived from the hydrolysis of pork loin by kiwifruit juice protease were evaluated. Methods: The pork loin was injected with 10% and 20% GRJ and GOJ, under various incubation times (0, 4, 8, and 24 h). Then, the physicochemical properties and tenderness of pork loins were measured. 2,2- diphenyl-1-picrylhydrazyl radical scavenging activity and reducing power were conducted to determine hydrolysate's antioxidant activities derived from pork loin's hydrolysis by kiwifruit juice protease. Results: GRJ had greater tenderizing ability than GOJ, even at the 10% addition. When kiwifruit juice was injected into pork loin, the tenderness increased with increasing incubation time. This was confirmed by the decrease in intensity of the myosin heavy chain (MHC) band in sodium dodecyl sulfate-polyacrylamide gel electrophoresis. In particular, the MHC band decreased at 8 h for both 10% GRJ and 20% GOJ and at 4 h for 20% GRJ alone. The highest myofibril fragmentation index and peptide solubility were observed in pork loin treated with 20% GRJ compared to the other treatments during incubation. The 10% GRJ and 20% GOJ treatments showed similar levels of antioxidant activity of the protein hydrolysates in pork loin, and 20% GRJ showed the highest activity among the treatments. Conclusion: Kiwifruit juice had protease activity, and GRJ was more useful for tenderizing meat products than GOJ. Thus, GRJ at 10% could be a potential agent to tenderize and enrich the natural antioxidant activity through the proteolysis of pork loin.

This study aimed to determine eco-friendly factors on the aspects of library service, materials provided or handled by the library, and programs including educational programs. Furthermore, it was setup to perform a trial evaluation for the eco-friendliness of the library based on the determined evaluation standards by this study. Results are as follows; First, regarding the question of 'Do employees of the library think that establishment of green libraries is necessary?', the employees of the libraries responded yes by 65.52%, but only 4.6% responded that it would not be necessary. Second, in analyzing the most important evaluation areas of green libraries according to the opinions of the libraries' employees, they were ranked in order: the indoor environment, energy and prevention of environmental pollution, and material and resource areas. Third, 11 areas were determined to evaluate the level of greening in the libraries; the highest averages were scored 510 for the area of energy and prevention of environmental pollution, 415 for the area of library resource, and 320 for the area of indoor environment. Last, the libraries were graded based on actual data according to the results to measure the level of greening, two libraries were graded as Diamond, the highest grade, accounting for 15.39% of all libraries; Gold and Silver grades accounted for another 15.39%, together five Certified graded libraries accounted for 38.46%, which was the highest rate among the libraries. Any library scoring less than 20% when compared to the full score was graded as Non-certified, and one library, which scored 15.06% fell into this category. The results of this study set up to serve as basic data for the direction of development for green libraries in our country, as well as reference for the employees of libraries in constructing or remodeling library buildings, establishing service infrastructure, providing information service, and planning library duties in an eco-friendly way.
