For the purpose of reproduction of traditional gold thread, the artifact investigation was organized for 70 cases (109 pieces) of relics from Korea, China and Japan. In most cases, the main backside material of gold thread from Korea was the bast fibers from paper mulberry. In this study, the optimum sheet-making of Hanji for gold thread reproduction was tried by controlling several process factors of Hanji such as the cooking and beating time of paper mulberry fibers, the number of sheet-making ply, and converting method (Dochim). Tensile index, folding endurance and compressive strength of Hanji showed differences according to the correlation between cooking and beating time, and application of converting method (Dochim), while bending stiffness fell with decrease of thickness. These results can be applied to consider manufacturing factors to make Hanji for the production of gold thread.

This study is on the consolidation process of the conservation process of fabric with golden thread found in relics. Gold film was glued to pieces of Korean paper and satin using hide glue, which is a natural adhesive and resin Paraloid B-72, which is a liquid type adhesive. This study examines the types and concentration of the adhesives that are appropriate for consolidating gold film on fabric. The advantage of hide glue is that it is harmless to humans and has a high stability. This glue is also believed to be the closest to the adhesive that was used when the relic was originally made. Its weakness is that it is stiff and weaker than chemical glues, but after being washed with water the adhesion level increases. Therefore, hide glue is appropriate in the following instances: a) when washing after consolidation b) when the substrate of gold threads are significantly damaged, and c) when treating greater sized relics that take a longer time to work on. However, Paraloid B-72 has a better adhesion and flexibility than hide glue, but tends to spread out into a greater area, and the area where it is applied tends to absorb less water than before the application. In addition, it is noxious and can be harmful in long-term exposure. Therefore, Paraloid-72 is appropriate in the following instances: a) when consolidating the fabric after washing, and b) when working on smaller relics and consolidating smaller parts of a relic. The necessary concentration levels for consolidants for gold film are 30% for liquid type hide glue and at least 10% for Paraloid B-72 in order for the gold film to stay intact on the fabric during washing, consolidation, exhibition, and conservation.

The purpose of this study is to figure out the types and characteristics of golden decoration technique out of various techniques of expressing patterns on the costumes. This study reviews both costumes decorated with gold in the relics of Chosun dynasty and literatures focused on domestic and Chinese documents and records. The types of decoration technique using gold include JigGeum (brocade technique), InGeum (gold powder and flake attaching technique), and GeumSaJaSu (embroidery technique). The JigGeum is weaved using golden thread instead of silk thread in order to express patterns. The InGeum technique is to attach gold or silver powder or thin gold or silver flake on the surface of the fabric. The GeumSaJaSu technique is to embroider with gold thread on fabrics. 82 pieces of costumes made using gold in Chosun dynasty era are analyzed. The results follows; In terms of types of technique, is shown to take the majority; JigGeum (43.90%), InGeum (30.49%), GeumSaJaSu (23.61%). Looking at the patterns used by the types, plant pattern and letter pattern are mostly used for both the JigGeum and the inGeum. In terms of the characteristics by their uses, the InGeum is used for court dresses (52%). It is also used for ordinary dresses (12%) and for other purposes (36%). It is mostly used in the court dresses in the late period of Chosun dynasty era. The JigGeum is used for ordinary dresses (47.22%), for court dresses (44.44%) and for other purposes (8.34%). It is evenly used for court dresses and ordinary dresses.

Objectives : The purpose of this study is to explore research trends in gold implantation therapy performed on the animal and human body, through a review of clinical studies focused on gold thread, gold needle and gold bead. Methods : Medical databases, including Pubmed, CENTRAL, MEDLINE, EMBASE, RISS4u, KISTI, OASIS and KTKP, were searched for relevant articles published from their launch to December 31, 2015 using the key word 'gold' with '$thread^*$', '$needle^*$', '$acupuncture^*$', '$wire^*$', '$bead^*$', '$embed^*$', '$implant^*$', or '$insert^*$'. The results were classified into in vivo studies, clinical trials and clinical reports. Analysis of the results was conducted in several research areas, from the identity of studies such as nationality and published year, to the gold preparations-features and implanted locations and to the outcomes that reflect the clinically favorable or adverse effect of gold implantation therapy. Results : A total of 30 studies including 11 in vivo studies, 4 clinical trials and 15 case reports, were found in the search. We observed certain research trends according to the research time, nationality and target indication of the studies. The studies primarily revealed a chronic local inflammatory response which could be a useful mechanism for pain-relief in musculoskeletal diseases and facial rejuvenation. Researches concerning long-term reactions or adverse effects were rare. Conclusion : The results show that the efforts to discover the level of clinical efficacy of gold implantation therapy were steady and worldwide. However, further researches on the longterm effect, and more importantly, the safety of gold implantation therapy are required.

The purpose of this study is to classify the types of and to examine the characteristics of the golden decoration technique used for expressing patterns on the costumes from Dang dynasty to Cheong dynasty era. In order to classify the types of the golden decoration technique and to examine its characteristics, literature review, focusing on documents and records of China, and investigation on the relics from Dang to Cheong Dynasty era were conducted. The types of decoration technique using gold include china JigGeum (brocade technique), InGeum (attaching gold powder and flake technique), GeumSaJaSu (embroidery technique), GeumSaTapestry, mixed technique. Interestingly, it was newly found in this study that embroidery with golden thread was used in the GeumSaTapestry technique and that there were some cases of the mixture of 2-3 gold decoration technique. The GeumSajaSu technique was used the most frequently from Dang dynasty to Yo dynasty era. However, its use had decreased enormously while the use of JigGeum had increased a lot since Geum dynasty era. The mixture of 2-5 techniques was used frequently in JigGeum, GeumSaJaSu, and GeumSaTapestry, but not used in InGeum. Particularly, the mixture technique was the most frequently used in the GeumSaTapestry, which expresses by composition of paintings. All four methods were used the mostly frequently in costumes, while GeumSaJaSu and GeumSaTapestry were generally used for home accessories. InGeum and GeumSaJaSu were used a lot for gaze and leno fabrics such as Sa or Ra, while JigGeum was mostly used for satin weaved fabrics like Dan.

In the Korean literature, records of systematic gold thread manufacturing such as gold foil(金 箔匠), gold foil bonded with fabrics(付金匠), gold foil bonded with paper materials(金箋紙匠), refining gold(鍊金匠), cutting gold(裁金匠), and making gold thread(絲金匠) can be easily found. We can infer from these literatures that the Korean people used to make gold threads. However, is not existent the gold thread making technique. Thus, a research was done using 67 pieces of gold thread artifacts used in textiles craft of Korea, China and Japan. The purpose of this research was to identify the characteristics of the Korean gold thread by studying the artifacts' form classification, gold foil, glue and the base. First, gold thread is divided into flat gold thread and wrapped gold thread. Wrapped gold thread was made in more various methods such as with a paper on the flat gold thread, metal thread and wrapped gold thread with gold foil on top. Compared to the flat gold thread, wrapped gold thread uses a thread that has a thinner and wider. Through this analysis, even making of the base of the gold threads was different according to the type. Secondly, we looked into the characteristics of materials according to form structure of the gold thread. After analysis of experiment results, we could know that to attach Korean gold thread, glue and the mixture of materials such as Red soil(朱土) was also added. The kinds of the base of gold threads were identified as paper, leather and intestines. Among those materials, for paper, Korea's Dakji, China's Sangpiji(桑皮紙) and Jukji(竹紙) and Japan's Anpiji(雁皮紙) seemed to have all been used, so because of the difference among countries, we can prove that Korea has also produced gold thread. By looking at the research, the base of gold threads and making features hugely vary according to the area.

본 연구에서는 논벼 이앙일수와 담수심의 변화가 논벼 수요량 산정에 미치는 영향을 분석해 보았다. 한국농어촌공사 관할지구인 금사, 중흥, 창평, 구성 지구를 대상으로 하여 2013년부터 2019년 기상자료를 활용하여 산정하였다. 이앙일수는 기존의 농업생산기반설계기준에서 제시한 일수 20일과 전국쌀전업농중앙연합회 소속 농업인을 대상으로 실시한 설문조사 결과를 기반으로 다양한 이앙기간을 적용하였다. 또한 담수심은 최소 0mm, 최대 100mm 범위에서 다양하게 적용해 보았다. 그 결과, 이앙기간이 길어질수록 이앙용수량이 증가하고, 궁극적으로 필지용수량과 논벼 수요량을 증가시켰다. 기존 설계기준인 20일의 이앙일수를 적용한 경우에 비해 이앙일수를 최대 51일 적용할 경우 필지용수량은 평균적으로 16.6 %, 논벼 수요량은 평균적으로 12.9 % 증가를 보였다. 이앙시기를 다르게 한 논벼 수요량과 현장의 농업용수 공급량을 비교 할 경우, 51일의 이앙기간을 적용한 논벼 수요량이 공급량과 가장 적은 차이를 나타내어, 이앙기간 51일이 실제 현장 여건을 가장 잘 반영하는 것으로 판단되었다. 담수심과 논벼 수요량과의 관계에서는 최소 담수심 증가는 수요량의 증가를 야기하였으며, 최대 담수심 증가는 수요량의 감소를 야기하였다. 통상적으로 필지에서 최소 담수심일 때 수요량이 발생하고, 최대 담수심일 때 유출량이 발생하는데, 논벼 생육기간동안 일별 담수심의 변화가 최소 담수심에 도달하여 수요량이 발생하는 일수가 최대 담수심에 도달하여 유출량이 발생하는 일수 보다 많기 때문에 발생된 결과로 사료된다. 따라서 논벼 생육기간 수요량이 크게 산정된 연도 일수록, 최소 담수심 변화가 수요량에 미치는 영향이 크게 나타났다. 결론적으로 이앙일수의 경우 농업현장을 기준으로 볼 때 기존 설계기준에서 제시하는 논벼 수요량은 실제로 소모되는 필요수량보다 작게 산정되는 것으로 파악되어 이앙일수를 현장여건에 부합되게 더 연장하여 적용하는 것이 필요하며, 담수심의 경우 기존의 설계기준보다 최소 담수심은 낮게, 최대 담수심은 높게 적용하는 것이 유효우량 산정에 적합할 것으로 사료된다. 또한 논벼 수요량 산정 결과의 신뢰도 향상을 위해 이앙시기, 담수심 조정 외에도 수로손실 및 침투인자 등에 대한 현장여건 반영도 필요할 것으로 사료된다.

A randomized, double blind, placebo-controlled human intervention study involving 62 healthy volunteers was performed to investigate the effects of Keumsa sangwhang (Phellinus linteus) mushroom extracts (KPLE) on natural killer (NK) cell activity in peripheral blood. The volunteers were randomly distributed into two groups, one receiving KPLE (3.3 g/day) and the other a placebo by oral administration for 8 weeks. In this study, the number of NK cells did not increase with KPLE administration, however the cytotoxic activity of NK cells against the Jurkat leukemia cell line increased significantly. This result suggests that administration of KPLE induces cell-mediated immunity by increasing NK cell activity in humans.

Promotion and marketing, which are essential to lower the investment risk and maximize commercial profit in the video game market. Game developers and publishers set up public relations strategies to encourage potential consumers' needs. Considering characteristics of video game, the trailer, which is the animated image advertisement material, could occupy a key position in its promotion and marketing plan. Cinematic spectacles and attractive narratives are essential ingredients for game trailers, which are usually produced in 3D animation. Dead Island is an open world first person shooters (FPS) game released in 2011. When launched, it grabbed a great attention with a trailer, awarded the Golden Lion Prize for the best internet film at the Cannes Lions International Festival of Creativity. The game was a commercial success and several spin-offs were producted. In 2014, its publisher, Deep Silver showed the official trailer of Dead Island 2 at Electronic Entertainment Expo, the world's largest game show. Dead Island 2 was scheduled to be released in 2016, but has been now delayed until 2018. This study compares and analyzes two trailers of Dead Island 1 and Dead Island 2. We examine the narrative structure of the trailer for the sequel promotion of a successful game. The differences between the two could be useful for building a promotion strategy of other game series.

This study identified material properties through scientific analysis on Jikgeumdan(satin with gold threads) from Donggungbi-Wonsam and the gold threads used in the embroidery. The Donggungbi-Wonsam's base of gold threads were estimated to have used mulberry fiber's Korean paper(Hanji) because non-wood-based fibers were observed. The X-ray spectrometer showed that the Tongsuseulan of Donggungbi-Wonsam was a flat gold thread of pure gold and Jikgeumdan of flat silver thread of its Saekdong and Hansam. High sulfur levels were detected in the flat silver thread, which appeared to have formed silver sulfide by either manufacturing process using sulfur or conservation environment. he dragon insignia's embroidery is also described as two types twisted gold threads; pure gold and alloying-gold and silver. while dragon insignia's border line is decorated with a twisted gold thread of pure gold. In particular, it was investigated that adhesives such as an animal glue, a protein-based compound by gas chromatography mass spectrometry. Additionally, XRF and Raman spectroscopy analysis on the mixture substances between the metal surface and the base paper of gold threads identified talc and quartz in the gold threads and Seokganju(hematite) in the flat silver threads.
