조선 인조대에 경기(京妓)가 폐지된 이후 생긴 향기(鄕妓)의 선상제도(選上制度)로 인하여 지방에서 공연되어 지던 교방정재(敎坊呈才)가 궁중으로 유입되어 궁중정재로 채택, 궁중연향에서 연행되었는데 그 대표적인 종목 중 하나가 선유락(船遊樂)이다. 선유락은 정조19년(1795) 『원행을묘정리의궤(園行乙卯整理儀軌)』에 최초로 기록된 이후 조선후기 궁중연향기록인 각종 의궤의 정재종목으로 빠짐없이 등장한다. 궁중정재 선유락을 담당한 여기(女妓)들이 당시 평안도 의주, 안주, 성천 등지에서 올라온 선상기(選上妓)들이었음을 고려할 때 이들에 의해 관서지방의 교방정재인 배따라기가 궁중으로 유입되고 궁중 정재 선유락으로 정착되었음을 추정할 수 있다. 궁중정재 선유락의 형성에 영향을 준 관서지방 교방정재인 배따라기는 명·청교체기후금이 요동지역을 장악하자 명나라 사행(使行)을 바닷길로 갈 수 밖에 없었던 수로조천(水路朝天) 당시의 일을 바탕으로 하여 교방의 기녀들에 의해 공연물로 탄생되었다. 관서지방은 중국으로 사행을 떠나는 사신들이 거쳐 가야 하는 지리적 특성 때문에 사신들을 위한 연향이 많았고 중국으로 떠나는 사신들을 위한 전별연(餞別宴)에 교방청 기녀들에 의해 험난한 사행길을 떠나야 하는 이별의 애끊은 아픔과 사신들의 무사귀환을 축원하며 배따라기가 연행되었다. 관서지방 배따라기 관련 많은 문헌에서 교방정재 배따라기가 수로조천 당시 배가 떠나가는 (船離) 이별의 아픔을 처절한 성조(聲調)와 행위로 공연작품속에 담아내고 있다고 기록하고 있다. 기록을 토대로 살펴본 관서지방 배따라기는 무구로 사용되는 그림배(畵船)가 등장하고, 동기 한 쌍을 뽑아 군사인 소교(小嬌)로 분장시킨 후 군례를 올리고, 행군을 의미하는 고취악을 연주, 행선 전 부르는 노래와 음악반주, 행선의 모습을 극적(劇的)으로 표현, 무사귀환을 축원하는 이별가(배 떠나는 노래)를 부르는 형식으로 공연을 구성하고 있다. 명·청 교체기 수로로 사행을 떠나는 사신을 이별하며 바닷가에서 배를 떠나보내며 벌어진 실제 상황을 이렇듯 악·가·무와 극적인 요소를 결합하여 공연물로 탄생시켰음을 알 수 있다. 이렇게 탄생된 관서지방의 교방정재 배따라기는 중국으로 가는 사신들을 위한 각종 연향에서 공연되어졌고 선상기들의 활동에 의해 궁중정재 선유락의 형성에 영향을 미쳤고, 궁중연향을 마친 선상기들의 귀향(歸鄕)으로 인해 다른 지방에도 유사한 형태의 공연물(『교방가요(敎坊歌謠)』 소재 「선악(船樂)」, 『이재난고(頤齋亂藁)』 소재 「행선곡무(行船曲舞)」)로 정착되어 지방의 연향에서 그 지방의 특색을 담아 서로 다른 절차로 공연되어졌다.

Background: Some reports have suggested that chronic myeloid leukemia (CML) patients have a higher prevalence of M-bcr than acute lymphoblastic leukemia (ALL) patients, which show a higher prevalence of m-bcr. However, the relationship between BCR-ABL subtypes and progression of CML and ALL remains unclear. Materials and Methods: 354 CML chronic phase (CML-CP) patients, 26 CML blastic phase (CML-BP) patients and 72 ALL patients before treatment with BCR-ABL positive were recruited for blood routine examination and bone marrow smear cytology. Some 80 CML-CP and 32 ALL patients after imatinib (IM) treatment were followed-up for BCR-ABL relative concentrations detected after treatment for 3, 6 and 9 months and 1 year. Results: Before treatment, CML-CP patients showed lower BCR-ABL relative concentrations with a higher proportion of M-bcr (42.7%) compared to CML-BP and ALL patients while ALL patients had a higher BCR-ABL relative concentration with high expression of m-bcr (51.4%). Patients with M-bcr demonstrated higher WBC counts than those with m-bcr and the mixed group and higher PLT counts were noted in the CML-CP and ALL groups. After imatinib (IM) treatment, patients with m-bcr showed higher BCR-ABL relative concentrations in both CML-CP and ALL groups. Conclusions: This study identified the BCR-ABL gene as an important factor in CML and ALL cases. The M-bcr subtype was associated more with CML while the m-bcr subtype was associated more with ALL. Patients with m-bcr seem to have a poorer response to IM in either CML or ALL patients compared to M-bcr patients.

Objectives : Our primary objective lies in understanding the current landscape of translational research on acupuncture, moxibustion and pharmacopuncture. Methods : We searched our own selection of keywords of acupuncture, moxibustion and pharmacopuncture and translational research from three overseas databases (Pubmed, Scopus, Medicine) and four domestic databases (DBpia, KISS, Riss4u, Korea Med). Results : We have chosen 41 articles in total-40 articles on acupunture, 6 article on moxibustion(5 articles were duplicated in use in each category). Origin-wise, 48.8 %/24.8 %/17.0 % of our articles pool came from USA/China/Korea, respectively. UK, Austria, Thailand and Italy contributed the rest of our article pool. For those articles written in USA and China, review articles were the most common type. For the US articles, all 10 review articles were non-systematic reviews, while, for China's contribution, one out of 4 review articles were systematic review. Type-wise, our research pool's breakdown is as follows ; 17 review articles, 11 experimental research, 2 randomized controlled trials(RCT), 1 clinical trial, 4 conference reports, 1 letter, 1 study protocol and 4 uncategorized. Topic-wise, brain-neurology was most frequently referred with 8 articles, followed by parkinson's disease (3 articles) and epilepsy (2 articles). Conclusion : 1. In terms of research submission articles, Korea appears to be lacking translational research on acupuncture, moxibustion and pharmacopuncture, compared to USA and China, in our view. 2. Unlike the cases of USA and China, most of Korean translational research is limited to doing a T1 level of translational research. In order to bring bench-to-bedside to light. we believe, there should be more studies, and thereby a certain level of activation, to the T2 level of translational research in Korea. 3. Further, in our view there should be more efforts to improve article quality at the T1 level of translational research, which eventually becomes the fundamentals of the next level of research (i.e. T2 research), as well as to increase the number of research submissions, going forward.

A satellite tracked drifter experiment was conducted to observe thermal structure and surface circulation in the northeastern East China Sea. For this experiment, four ADOS buoys, assembled with surface float and thermister chain, were deployed on August 2007 in southern Jeju-do, where the Kuroshio Branch Current is separated from the main stream. Thermal structure in the upper layer of the northeastern East China Sea was successfully observed during the following $1{\sim}3$ months. Strong thermo-haline front in a northeast-southwest direction was observed. In the frontal zone, warm and saline Kuroshio origin water intermixes with fresher coastal water and flows toward the Korean Strait. Typhoon Nari, which passed over the East China Sea 20 days after commencement of study, caused distinct signals in the thermal structure and trajectory of buoys. During the typhoon, surface temperature abruptly dropped to about $4^{\circ}C$, while the thermocline formed at $30{\sim}50$ m depth vanished due to strong vertical mixing. Internal inertial oscillation occurred several days after the typhoon. The fortuitous occurrence of typhoon Nari showed that ADOS buoys can provide useful and accurate air-sea interaction data during typhoons.

This study examines the dietary life, weight control, perceived body image, self-esteem, and eating disorder of female college students residing in Korea and China. With approval by the IRB of Pusan National University, a survey was conducted in Korea and China. A total of 574 subjects participated in the survey, and they were divided into three groups: 153 Korean female college students residing in Korea (KSK), 180 Chinese female college students residing in Korea (CSK), and 241 Chinese female college students residing in China (CSC). The group of underweight subjects far exceeded the overweight and obese groups, but there was no significant difference (p<0.05). The CSC group showed the highest food intake frequency and eating habit scores, and the KSK group, the lowest (p<0.05). However, the KSK group showed the highest daily life habit score, followed by the CSK and CSC groups, in that order. All groups showed high weight control experience rates mainly for losing weight. In particular, the KSK group showed a much higher rate than the CSC and CSK groups. All groups wanted much thinner body shapes than their actual shapes, resulting in high percentages of body image dissatisfaction. The KSK group showed a higher self-esteem score than the CSC group. The average EAT-26 score was similar across the three groups, but the percentage of eating disorders was much higher in the KSK group than in the CSC and CSK groups.

Objectives : Korea and China are applying different conversion standards for weight in traditional medicine books. This study aims to research and suggest how to convert the units of weight in old traditional medicine classics into the contemporary unit of grams. Methods : Historical documents of Korea and China were used to review the process in which weights and measures changed in each country and the manners in which the Chinese units of weight were introduced to Korea. Results : Weights and measures changed with time. They became almost standardized by the period of Song in China, when coins played the most crucial role, and it was introduced to Korea. Donggaryang, the standard container for weights and measures in ancient China, Gaewontongbo, a coin in Tang, Sangpyeongtongbo, a coin in Joseon, and a scale in Joseon were used as strong foundations for conclusion from literature review. Weight of a 1-don(coin) in the time a traditional medicine books were written was used as a unit of weight in those books. Sangpyeongtongbo, a 1-don coin in Joseon, weighs 4 grams on average. Conclusions : Since the current conversion of 1-don coin into 3.75 grams is not supported by literature review, it is suggested that 1-don(coin) as a unit of weight in traditional medicine books of Joseon, may be better converted into 4 grams, while that of China is converted to 3.73 grams.

In-band full-duplex (IBFD) wireless communication supports symmetric dual transmission between two nodes and asymmetric dual transmission among three nodes, which allows improved throughput for distributed IBFD wireless networks. However, inter-node interference (INI) can affect desired packet reception in the downlink of three-node topology. The current Half-duplex (HD) medium access control (MAC) mechanism RTS/CTS is unable to establish an asymmetric dual link and consequently to suppress INI. In this paper, we propose a medium access control mechanism for use in distributed IBFD wireless networks, FD-DMAC (Full-Duplex Distributed MAC). In this approach, communication nodes only require single channel access to establish symmetric or asymmetric dual link, and we fully consider the two transmission modes of asymmetric dual link. Through FD-DMAC medium access, the neighbors of communication nodes can clearly know network transmission status, which will provide other opportunities of asymmetric IBFD dual communication and solve hidden node problem. Additionally, we leverage FD-DMAC to transmit received power information. This approach can assist communication nodes to adjust transmit powers and suppress INI. Finally, we give a theoretical analysis of network performance using a discrete-time Markov model. The numerical results show that FD-DMAC achieves a significant improvement over RTS/CTS in terms of throughput and delay.

This paper presents the seismic behaviors and restoring force model of ring beam joints of steel tube-reinforced concrete column structure under cyclic loading. First, the main failure mode, ultimate bearing capacity, stiffness degradation and energy dissipation capacity are studied. Then, the effects of concrete grade, steel grade, reinforcement ratio and radius-to-width ratios are discussed. Finally, the restoring force model is proposed. Results show that the ring beam joints of steel tube-reinforced concrete column structure performs good seismic performances. With concrete grade increasing, the ultimate bearing capacity and energy dissipation capacity increase, while the stiffness degradation rates increases slightly. When the radius-width ratio is 2, with reinforcement ratio increasing, the ultimate bearing capacity decreases. However, when the radius-to-width ratios are 3, with reinforcement ratio increasing, the ultimate bearing capacity increases. With radius-to-width ratios increasing, the ultimate bearing capacity decreases slightly and the stiffness degradation rate increases, but the energy dissipation capacity increases slightly.

Purpose: To compare the clinicopathological data and long-term survival of gastric cancer patients in China and Korea. Materials and Methods: Patients who had undergone gastrectomy for gastric cancer between 1998 and 2009 in 2 high-volume institutions in both China (n=1,637) and Korea (n=2,231) were retrospectively evaluated. Clinicopathological variables, overall survival (OS), progression-free survival (PFS), and surgery-related complications were assessed for all patients and compared between the 2 institutions. Results: Chinese patients included in the study were significantly older and had a significantly lower body mass index (BMI) than the Korean patients. Esophagogastric junction tumors were more frequent in Chinese patients. However, the number of patients with stage I gastric cancer, the number of harvested lymph nodes, and the number of total gastrectomies were significantly higher in the Korean population. Korean patients also presented with fewer undifferentiated tumors than Chinese patients. Furthermore, Korean patients had prolonged OS and PFS for stage III cancers only. BMI, tumor-node-metastasis (TNM) stage, tumor invasion, number of positive lymph nodes, and distant metastases were all independent factors affecting OS and PFS. Conclusions: Although China and Korea are neighboring Asian countries, the clinicopathological characteristics of Chinese patients are significantly different from those of Korean patients. Korean gastric cancer patients had longer OS and PFS than Chinese patients. Influencing factors included TNM stage, tumor invasion, and lymph node metastasis.

The recent interest in artificial intelligence and machine learning has partly contributed to an interest in the use of such approaches for hyperspectral remote sensing (HRS) imagery classification, as evidenced by the increasing number of deep framework with deep convolutional neural networks (CNN) structures proposed in the literature. In these approaches, the assumption of obtaining high quality deep features by using CNN is not always easy and efficient because of the complex data distribution and the limited sample size. In this paper, conventional handcrafted learning-based multi features based on expert knowledge are introduced as the input of a special designed CNN to improve the pixel description and classification performance of HRS imagery. The introduction of these handcrafted features can reduce the complexity of the original HRS data and reduce the sample requirements by eliminating redundant information and improving the starting point of deep feature training. It also provides some concise and effective features that are not readily available from direct training with CNN. Evaluations using three public HRS datasets demonstrate the utility of our proposed method in HRS classification.
