Magoja is a jacket for men and women. Magoja was worn between the jacket, jogori and the coat durumagi; that is over the jacket and under the coat. In the 19th century, Daewon-kun, who was wearing maqua, was in China and he came back to Korea. So, it was believed that the origin of magoja was from maqua from Qing. But, there were differences between magoja and maqua in their design. Therefore, I researched the origin of magoja and tried to know the design and the method of wearing magoja in the Chosun dynasty. The results are as follows. The design of magoja, especially its collar, was different from Chinese maqua. As analyzed above, it is difficult to regard the origin of magoja as deriving from Daewon-kun's maqua, which he wore when he went to Qing. Magoja-style jacket can be found from many old pictures. The collar of those jacket, whose style was waonsam-git unlike the present-day magoja, is consistent with the collar of sagyusam or baeja. And this kind of git style had existed for a long period of time as already studied in bangryungbangbi. Furthermore, the origin of this kind of jacket dated back to the maeksu of the Sung Dynasty; maek meaning Koguryo, maeksu was understood to indicate the style of the Koguryo jacket of short sleeves for the convenience of horseback riding. Maeksu, which varied in its kind and style, had been used as the equestrian clothes in China and was assumed to be particularly put on widely during the Yuan and Sung Dynasties. Maeksu continued to exist as daegeumeui during the Ming Dynasty but, later called magua, it was worn more widely ding the Qing Dynasty of the Manchus. This kind of maeksu or magua was the jacket which could be put on the coat and this style of wearing it during the Chosun Dynasty could be confirmed by the pictures. Therefore, magoja is not the jacket which was all of sudden derived from Qing's magua but one of traditional Korean clothes of the northern provinces which had existed for a long period of time. And magoja seemed to be put on more widely during the latter part of the Chosun Dynasty because of the influence of Qing's magua.

Gonadotropin-releasing hormone receptor (GnRHR) gene is expressed at the anterior pituitary gland and plays a key role in gonad development. This study aimed to investigate molecular genetic characteristics of the GnRHR gene and elucidate the effects of single nucleotide polymorphisms (SNPs) of GnRHR gene on sex steroid level in Japanese flounder (Paralichthys olivaceus). We used polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP) and sequencing of the GnRHR gene in 75 individuals. We identified three SNPs in the GnRHR gene: P1 locus (C759A and C830T) in the coding region of exon2 which were both linked together and P2 locus (G984T) in the coding region of exon3, which added a new transcript factor (ADR1) and a new methylation site (CG). Only C830T of P1 leads to amino acid changes Thr266Ile. Statistical analysis showed that P1 was significantly associated with $17{\beta}$-estradiol ($E_2$) level (p<0.01) and gonadosomatic index (GSI) (p<0.05). Individuals with genotype BB of P1 had significantly higher serum $E_2$ levels (p<0.01) and GSI (p<0.05) than those of genotype AA or AB. Another SNP, P2, synonymous mutation, was significantly associated with GSI (p<0.05). Individuals with genotype AB of P2 had significantly higher GSI (p<0.05) than that of genotype AA. In addition, there was a significant association between one diplotype based on three SNPs and reproductive traits. The genetic effects for both serum $E_2$ level and GSI of diplotype D4 were super diplotypes (p<0.05). These results suggest that the SNPs in Japanese Flounder GnRHR are associated with $E_2$ level and GSI.

The purpose of this essay is threefold. First, to highlight research of Seonmin KIM, whose 2006 Ph.D. dissertation elucidates complex relationships among Ming China, Choson Korea, Tokugawa Japan, and mountainous ginseng-producing "borderlands" between Korea and China; her story concludes with the remarkable rise of a borderlands power that overthrew Ming China, there-by establishing dominance that lasted into the $20^{th}$ century - the Qing Dynasty. A second purpose is to showcase application of a non-standard-model - the Hydraulic Metaphor - that elucidates economic components of Professor KIM's history via visual and intuitive mechanisms designed to be understandable for non-specialists. Last, an outline of East Asian history is placed within context of centuries of monetary evolution that eventually yielded the late-$16^{th}$-century birth of globalization.

In 1882, after the French defeated Tonkin for the second time, the Nguyen Dynasty led by King Tự Đức 嗣德 appointed Phạm Thận Duật 范慎遹 and Nguyễn Thuật 阮述 as envoys to the Qing Dynasty to seek the Chinese's help to deal with the French invasion. The trip's information from 1883 such as the schedule, the content, the discussion, and the progress was specifically reflected in the two envoys' diaries, including "Notes of Voyage to Qing Dynasty in The First Year of Jianfu" 建福元年如清日程 (Phạm Thận Duật and Nguyễn Thuật), "Notes of Voyage to Tianjin" 往津日记(Nguyễn Thuật). This article presents the origin of these documents and their historical values in order to provide insights into the study of diplomatic relations between the Nguyen Dynasty and the Qing Dynasty in the late 19th century through the 1883 mission.

The switching frequency of the power electronic devices used in large synchronous motor drives is usually kept low (less than 1 kHz) to reduce the switching losses and to improve the converter power capability. However, this results in a couple of problems, e.g. an increase in the harmonic components of the stator current, and an undesired cross-coupling between the magnetization current component ($i_m$) and the torque component ($i_t$). In this paper, a novel complex matrix model of electrically excited synchronous motors (EESM) was established with a new control scheme for coping with the low switching frequency issues. First, a hybrid observer was proposed to identify the instantaneous fundamental component of the stator current, which results in an obvious reduction of both the total harmonic distortion (THD) and the low order harmonics. Then, a novel complex current controller was designed to realize the decoupling between $i_m$ and $i_t$. Simulation and experimental results verify the effectiveness of this novel control system for EESM drives.

This research studies how a rain coat (兩衣) had developed in ancient China by searching through historic records. It can be said that people in ancient China wore two kinds of rain coats: straw coat and oiled-cloth coat (油衣). Straw coat was originally used in the Spring and Autumn and Warring States period. Then, people used natural grasses to make it. As the overall production had increased, various kinds of rain coats began to appear in Tang (唐) Dynasty, and the straw coat itself became elaborate. In Song (宋) and Yuan (元) Dynasty, the straw coat was used for the army, and when it came to be Ming (明) and Qing (淸) age, wearing it was considered a symbol of hermit. The straw coat shows the early form in the history of clothing, which was mostly put on by the poor. The material for straw coat was the grass which grows up in wet land area. People in the city and in the country had worn the straw coat for a long time. As foreign cultures were introduced, however, it disappeared first in cities and later in the country. The oiled-cloth coat was another of the kind. Its major material was water-proofed silk in the Qin(泰) and Han(漢) Dynasty. Also, it was a favorite of an emperor or aristocrats. Common people put on straw coat until the time the western rain coat was introduced and accepted in Qing Dynasty.

Rotor initial position is an important factor affecting the control performance of electrically excited synchronous motors. This study presents a novel method for estimating rotor initial position based on sliding discrete Fourier transform (sDFT). By injecting an ac excitation into the rotor winding, an induced voltage is generated in stator windings. Through this voltage, the stator flux can be obtained using a pure integral voltage model. Considering the influence from a dc bias and an integral initial value, we adopt the sDFT to extract the fundamental flux component. A quadrant identification model is designed to realize the accurate estimation of the rotor initial position. The sDFT and high-pass filter, DFT, are compared in detail, and the contrast between dc excitation and ac injection is determined. Simulation and experimental results verify that this type of novel method can eliminate the influence of dc bias and other adverse factors, as well as provide a basis for the control of motor drives.

만주족의 선조인 여진족은 그들이 거주하는 만주의 자연환경에 따라 채집과 수렵활동을 주된 생계수단으로 삼았다. 여진족의 거주지는 대부분 삼림이 울창하고 하천이 발달하여 다양한 동식물의 서식지로는 적합했지만 농경에는 맞지 않았다. 여진족 사회조직 역시 채집과 수렵활동에 적합한 방식으로 형성되었고 그것은 이후 청나라 고유의 사회 군사조직인 팔기제도로 발전했다. 한편 채집과 수렵으로 획득한 자연자원을 주변의 농경사회과 교환하는 일은 여진 사회의 발전에 절대적으로 중요했다. 인삼을 비롯한 만주의 자연자원을 중원의 한인들과 교역하는 일은 오래전부터 있었지만, 대외무역이 여진 사회에 근본적인 변화를 초래할 만큼 확대된 것은 16세기의 현상이었다. 당시 외부에서 유입된 은은 중국 내지의 경제를 활성화시키고 나아가 만주를 비롯한 명의 변경지역의 경제에도 큰 영향을 미쳤다. 만주의 자연환경에 기초한 수렵 채집활동이 16세기에 이르러 중원에서 유입된 은과 조우하여 변경 사회를 자극했고, 분산되어 있던 여진 부락은 경쟁과 통일의 과정을 거쳐 마침내 만주족으로 변모하여 1636년 청나라를 건설하기에 이르렀다. 1644년 만주족은 중원 정복에 성공하고 북경으로 수도를 옮겼다. 중원으로 들어간 후에도 청황실의 만주족은 만주 인삼의 가치를 잊지 않았을 뿐만 아니라 그 이익을 독점하기 위해 많은 노력을 기울였다. 17세기 말까지 만주 인삼은 만주족의 제도인 팔기를 중심으로 운영되었다. 만주에 주둔한 팔기 병사들은 민간인의 출입을 통제하여 인삼의 생산지를 한인의 접근으로부터 보호했다. 만주 인삼의 채취는 황실 내무부, 부트하 울라 총관, 성경상삼기 등 황제에게 직속된 기구에서 담당했다. 이들은 부트하 병정이나 팔기 병정을 파견하여 지정된 장소에서 정해진 액수의 인삼을 채취하여 납부하게 했다. 황실의 귀족만이 만주에 사람을 보내 인삼을 채취할 수 있는 특권을 누렸고, 그조차 엄격히 제한되었다. 18세기도 만주의 인삼은 여전히 국가에 의해 독점적으로 관리되었다. 청의 인삼 정책은 황실의 발상지인 만주와 그 자연자원을 민간인의 침탈로부터 보호하고 만주족 고유의 전통을 유지한다는 원칙에 따라 운영되었다. 동시에 만주의 인삼은 국가의 중요한 재정 수입원으로 개발되었다. 국가가 필요한 만큼의 수입을 징수하기 위해서는 인삼을 대량으로 채취해야 했는데, 부트하 병정이나 팔기 병정을 파견하는 것만으로는 안정적인 인삼세수를 기대할 수 없었다. 그 결과 상인들이 인삼업에 개입하기 시작했고 청의 인삼 정책은 이후 점점 더 상인에 의존하는 방향으로 발전해갔다. 청대 인삼의 국가 독점은 1853년에 공식적으로 중단되었지만, 부유한 상인이 채삼인을 고용하고 인삼을 대신 납부하는 현상은 18세기에 이미 나타나고 있었다. 청대 만주족의 인삼 독점은 사실상 한인 상인의 참여로 유지되었다고 할 수 있다.
