This case report presents a 34-year-old female patient. Her chief complaints are akinetic mutism and cognitive dysfunctions. We have diagnosed her with leukoencephalopathy. She was treated with Korean traditional herbal medicines (Joojackwhan) for 33 days continuously. The effects of treatment were measured by the Korean Mini - Mental State Examination and Modified Bathel Index. After treatment, her chief complaints have been improved. Furthermore, the K-MMSE, MBI scores increased. From this case, we deduced that the Korean traditional herbal medicines (Joojackwhan) could be effective for cognitive dysfunctions and akinetic mutism caused by leukoencephalopathy.

Akjang yoram 『樂章要覽』 is a book that summarizes only the important contents from the Akjang 樂章. Akjang 樂章 is arranged in the first half, and score 樂譜 is arranged in the second half. It seems that Akjang yoram 『樂章要覽』 passed through a total of four stages through the time when the handwriting and the lyrics were written. The presence of various handwriting and traces of modifications means that it has been passed through by several people, so it is not unrelated to the fact that several traces remain on the back of the cover of Akjang yoram 『樂章要覽』. The first part of the Akjang 樂章 is a method of presenting the name and lyrics of the accompanying music based on the ritual procedure, and in particular, the lyrics are written in Chinese characters and Hangeul sounds to improve readability. The score in the second half complies with the ritual procedures, but boldly omits overlapping melodies, and is composed based on the music, and various symbols are used to capture the expression of court music. This structure is a reflection of the direction we practiced to harmonize with the music after prior ritual procedures and diction. This was a device to increase the efficiency of music education and music practice for the court musician. The characteristics of the musical pieces are that they consist of essential musical pieces that must be mastered as musicians. In addition, the name Kim Hyung-sik 金亨植 is noted on the back cover of Akjang yoram 『樂章要覽』, and he was a court musician who was active in the age of King Sunjo 純祖. In other words, the musical pieces included in Akjang yoram 『樂章要覽』 are the core repertoire played by court musicians like Kim Hyung-sik 金亨植. Akjang yoram 『樂章要覽』 is a 'music practice booklet' containing the daily life of court musicians. Akjang yoram 『樂章要覽』 is a booklet designed for the purpose of teaching the court musicians to sing while correctly pronouncing the lyrics in major ceremonies. It is even more noteworthy in that Kim Hyung-sik 金亨植 was an owner. In addition to the fact that Kim Hyung-sik's name remains, and in the practicality of being used by various court musicians reflecting and modifying the changes of the times, it is meaningful in that it contains the path of court musicians who spent a lot of time and time to transmit court music.

In this study, we investigated the effects of copper and copper-alloy on the frictional and wear properties of low-steel friction material. The proportions of copper and copper-alloy in the brake friction materials used in passenger cars are very high (approximately 5-20% weight), and these materials have significant effects on friction and wear characteristics. In this study, the effects of cupric ingredients, such as the copper fiber and brass fiber, are investigated using the friction materials based on commercial formulations. After the copper and brass fibers from the same formulation were removed, the frictional and wear characteristics were evaluated to determine the influence of the copper and copper-alloy. We evaluated the frictional and wear characteristics by simulating various braking conditions using a 1/5 scale dynamometer. The results show that the friction material containing copper and brass fibers have excellent frictional stability and a low wear rate compared to the friction material that does not contain copper and brass fibers. These results are attributed to the excellent ductility, moderate melting point, high strength, and excellent thermal conductivity of copper and copper-alloy. We analyzed the surfaces of the friction materials before and after the performing the friction tests using a scanning electron microscope-energy dispersive X-ray spectroscope, confocal microscope, and roughness tester to verify the frictional behavior of copper and copper-alloy. In future studies, it will be applied to the development of copper-free friction materials based on the results of this study.

In this study, we investigate the mechanical properties of high manganese steel, and the friction and wear characteristics of brake friction material containing this steel, for passenger car application, with the aim of replacing copper and copper alloys whose usage is expected to be restricted in the future. These steels are prepared using a vacuum induction melting furnace to produce binary and ternary alloys. The hardness and tensile strength of the high manganese steel decrease and the elongation increases with increase in manganese content. This material exhibits high values of hardness, tensile strength, and elongation; these properties are similar to those of 7-3 brass used in conventional friction materials. We fabricate high manganese steel fibers to prepare test pad specimens, and evaluate the friction and wear characteristics by simulating various braking conditions using a 1/5 scale dynamometer. The brake pad material is found to have excellent friction stability in comparison with conventional friction materials that use 7-3 brass fibers; particularly, the friction stability at high temperature is significantly improved. Additionally, we evaluate the wear using a wear test method that simulates the braking conditions in Europe. It is found that the amount of wear of the brake pad is the same as that in the case of the conventional friction material, and that the amount of wear of the cast iron disc is reduced by approximately 10. The high manganese steel is expected to be useful in the development of eco-friendly, copper-free friction material.

This study is aimed at researching Gyobang Dance performed by gisaeng of Gyobang in the banquet of Tonshinsa in Yeongnam Jwa-do Province. For this study, Hae-haeng-chong-che, a collection of 28 travel essays written by Joseon Tonshinsa after visiting Japan, and a collection of literary works were analyzed. Joseon Tonshinsa used Yeongnam Jwa-do Province as a route to Japan in obedience to a royal command, and Yeongnam U-do Province as a way back to Hanyang after completing their missions. The country gave a huge banquet to relieve Tonshinsa's anxiety about the voyage and to pray for a safe trip. The banquets were concentrated in Yeongnam Jwa-do Province, the way down to Busan departing from Hanyang. Looking into Tonshinsa's records, it can be seen that Tonshinsa banquets took place in Andong, Yeongcheon, Gyeongju, Milyang, and Busan. Gyobang Dance performed at Tonshinsa banquets includes Geommu, Hwangchangmu, Cheoyongmu, Cheondo, Mudong, Ipchum, and Jungchum. Through Tonshinsa envoy, 'Jeseon Tonshinsa-gil' was formed in Yeongnam Jwa-do Province, and through Tonshinsa banquets, the artistry of Gyobang Dance was compiled. Nevertheless, present Yeongnam Jwa-do Province has remarkably less Gyobang Dance passed down in comparison to Yeongnam U-do Province. For this reason, there is a need to look into Gyobang Dance of Yeongnam Jwa-do Province. The purpose of this study is to closely examine the cultural and artistic characteristics of Gyobang Dance performed at Tonshinsa banquets in Yeongnam Jwa-do Province formed through Joseon Tonshinsa-gil.

This study examines and compares music-related records in the mubo (舞譜; choreography notes) written by Sung Gyeonglin (成慶麟, 1911 - 2008), based on the records of 11 kinds of jeongjae (the music and dance performances at the royal court) found in Lee Byungseong's (李丙星, 1909 - 1960) Changsa and Jungjaecheol (呈才及唱詞綴). Even though these records are personal, they provide valuable information about the mubo of the Iwangjikaakbu (the Royal Music Institute) during the period of Japanese colonization. The eleven kinds types of jeongjae-'Cheoyongmu (處容舞)', 'Hyangryungmu (響鈴舞)', 'Mugo (舞鼓)', 'Bosangmu (寶相舞)', 'Chunangjeon (春鶯?)', 'Gainjeonmokdan (佳人剪牧丹)', 'Suyeonjang (壽延長)', 'Mansumu (萬壽舞)', 'Bongraeeui (鳳來儀)', 'Jangsaengboyeonjimu (長生寶宴之舞)', and 'Musanhyang (舞山香)'-can be largely divided into two types: Dangak (Tang dynasty music) and 'Hyangak (traditional Korean music).' The former is distinguished musically by whether or not the jukganja appears. For the appearance of the jukganja in 'Sujeyongjang', 'Bongraeeui' and 'Jangsaengboyeongjimu', the 'boheojaryung (步虛子令)' was used and given the impressive name of jangchunbullojigok (長春不老之曲).' The term punggyungjigok (豊慶之曲)' was used for music that guides a group dance and dancers. For the latter, hamnyungjigok (咸寧之曲) was performed during the development of the dance, and the pungungyeonghoijigok (風雲慶會之曲) was played at the end of the piece. As for the accompaniment for the jeongjae performed by the Iwangjikaakbu, it is significant that various elaborate names were attached to Sangryungsan, Jungryungsan, Seryungsanm, Garakdeoli, Samhyunhwanip, Yeombulhwanip, and taryung (the traditional Korean ballad), which were all parts of 'Samhyunyoungsanhoesang (靈山會上).' Specifically, the 'Hyangdanggyoju (鄕唐交奏)' in 'Jeongjaemudoholgi' was accompanied by various melodies of the 'Samhyunyoungsanhoesang', which were given extravagant names. These are the personal records of the Iwangjikaakbu mubo that were retained by Lee Honggu (李興九, b. 1940), who owns the 'Hakyeonhwadaehapseolmu.' Among them, the ten kinds of jeongjae found in the notes of Sung Gyeonglin are often referred to as 'mueui (舞儀)' and widely used for research on individual jeongjae performances and the history of their development. The notes of Lee Byungseong have not been investigated thoroughly until now and this is the first study that provides a comparative analysis of the notes of Lee Byungseong and Sung Gyeonglin. This investigation is expected to contribute to the further research and knowledge of the jeongjae performance during the period of Japanese colonization.
