Total 438 precipitation samples were collected in Jeju City between 1997 and 2005, and their major ionic components were analyzed. The comparison tests using ion balance, electric conductivity and acid fraction were performed. It was found their correlation coefficients were in the range of 0.977$\sim$0.994, indicating the good quality of collected dam. The volume-weighted mean pH and electric conductivity were 4.8 and 23.0 $\mu$S/cm, respectively. with the ionic strength of 0.23$\pm$0.20 mM. The marine ($Na^+$, $Mg^{2+}$, and $CI^-$), anthropogenic (nss$SO_4{2-}$, $NO_3^-$, and $NH_4^+$) and soil (nss-$Ca^{2+}$) species have contributed to the ionic components of precipitation samples with 43$\sim$74%, 16$\sim$37% and $\sim$5%, respectively. The seasonal variations of $NO_3^-$ and nss-$SO_4^{2-}$ showed a distinct seasonality with higher concentrations in winter than summer, indicating an increase of fossil fuel consumption and a possibility of long-range transport of those pollutants from continental area along the dominant winter westerly. The levels of nss-$Ca^{2+}$ also were appeared the highest in winter and increased comparatively in spring season. possibly due to the soil influences including the Asian Dust. The acidification contribution of nss-$SO_4^{2-}$ and $NO_3^-$ showed 88$\sim$96%, and the free acidity was in the range of 6.0$\sim$40.1%. Interestingly, the backward trajectories for the case of upper 10% nss-$SO_4^{2-}$ and $NO_3^-$ levels have passed through the China continent before their arrival to Jeju. The precipitation of pH below 4.5 has been occurred frequently when the trajectory's path lied over the China continents. On the other hand, the air masses from the North Pacific area were characterized by lower 10% of nss-$SO_4^{2-}$- and $NO_3^-$ concentration, which demonstrated that air mass from the North Pacific was the cleanest among air masses moved to Jeju.

Objective: To evaluate the relationships between lymph node ratio (LNR, the ratio of positive lymph nodes in excised axillary lymph nodes) and disease-free survival (DFS) by comparing with traditional absolute positive lymph node number (pN classification) for prediction of breast cancer (BC) progrnosis. Methods and Patients: We retrospectively reviewed patients who received comprehensive therapy in Department of Breast Surgery, Hubei Cancer Hospital, China from Jan 2002 to Dec 2006 (Group A), and Department of Breast and Thyroid Surgery, Renmin Hospital of Wuhan University, China from Jun 2008 to May 2012 (Group B). Patients were allocated to low-risk (${\leq}0.20$), intermediate-risk (> 0.20 but ${\leq}0.65$), high-risk (>0.65) groups by LNR. The primary endpoint was 5-DFS. Results: A total of 294 patients were included in our study. LNR was verified as a negative prognostic factor for DFS (P=0.002 in Group A, P<0.0001 in Group B). Then we found the effects of pN and LNR delamination on disease-free survival (DFS) had statistical significance (P=0.012 for pN and P=0.031 for LNR stratification in Group A, both of them P<0.001 in Group B). Compared to pN staging, LNR staging displayed superior performance in prognosis, the adjusted hazard ratio of recurrence being 2.07 (95%CI, 1.07 to 4.0) for intermediate risk group (P=0.030) and 2.44 (95%CI, 1.21 to 4.92) for high risk group (P=0.013) in Group A. Conclusions: LNR stratification proved an adverse prognostic factor of DFS in lymph nodes positive invasive BC using cut-off values 0.20 and 0.65, and was more predictive than traditional pN classification for 5-DFS.

The Pulse diagnosis is in the boundary of the Four Examinations, and it is called 切診, or palpation. It has a great impact on people in reminding of the Traditional Medicine that it is probably the first thing that people think of when they hear about Traditional Medicine. Hu-Jun quoted in the Treasured Mirror of Eastern Medicine "東醫寶鑑" that the doctor finds out the deficiency and the excess of the meridian of the patiant through the pulse, and that it is of the utmost necessity to know the "deficiency and the excess" of the meridian to decide the formula (君臣佐使) of the herbal medicine and the acupuncture/moxibustion treatment. The research on the studies of pulse diagnosis have been concentrated on the origin, history, and the theory of the pulse diagnosis throughout the years; however, the number of research on the image from the classics on pulse diagnosis have been less. With this in mind, this paper was written to study more on the origin and the history of the pulse diagnosis as well as to study on the image of pulse diagnosis shown on the classics on Traditional Medicine in China and Korea. The history of the pulse diagnosis has its root on the attempt to find out what is happening inside the body through the indication of the small changes of the pulse that is shown on the outer boundaries of the body. There were various kinds of pulse diagnosis including "Three positions and nine indicators method" and "Carotid pulsation and wrist pulse method" in the ancient period, and wrist pulse-taking method became the most popular since the completion of studying on palpation by 初보. The image of the palpation helps the rudimentary practitioners of Traditional Medicine. They are divided into two large categories, which are the area of diagnosis and the shape of the pulse itself. The historical classics including the image of the pulse diagnosis can be found since the Song Dynasty of China. There are various kinds of image of pulse diagnosis in the classic such as "The picture of the hand meridian" from "脈訣指掌病式圖說", "The picture of the image of meridian" from "察病指南", "The picture of the Seven exterior and Eight interior" from "校正圖注脈訣", and "The picture of the six parts of meridian" from Treasured Mirror of Eastern Medicine "東醫寶鑑". The Treasured Mirror of Eastern Medicine "東醫寶鑑" have analyzed the basic theories and made up the standards of pulse diagnosis by establishing "The picture of the six parts of meridian" based on "The method of placing the viscera and bowels corresponding to cun-guan-qi, or the meridian".

The present study aimed to understand the taste of literati appearing in the Korean-Chinese garden by comparing "Yanghwasorok(養花小錄)" and "Zhangwuzhi(長物志)", which are one of the representative gardens in Korea and China. The main subject of comparison is plants; the research results are as follows. First, Gang Hui-an stated that the ultimate purpose of growing and appreciating the gardening plants is the completion of oneself, while Wen Zhen-heng(文震亨) used gardening plants as a means to practice a life of reclusiveness(隱逸). Second, Gang Hui-an claimed that growing plants is human's cultivation of virtue on the basis of Confucian view's gaining knowledge by the study of things(格物致知), whereas Wen Zhen-heng realized the taste of 'elegance(雅趣)' through form of plants or planting method. Third, although plant preference of literati of both countries is similar in many parts, there is a slight difference for putting gardening plants in pots and appreciating them. For example, even for selecting or placing pots, simplicity and lightness are characteristically reflected from Gang Hui-an while splendor and refinedness are characteristically shown from Wen Zhen-heng. Moreover, in light of the taste of appreciation of literati of the Song Dynasty(宋代), which is a sample of literati spirit, Gang Hui-an inherited the inner world of the spirit whereas Wen Zhen-heng expressed 'literati-ness' in visual images.

Solid phase microextraction and gas chromatography-mass spectrometry (SPME/GC-MS), electronic nose, and electronic tongue were used to characterize the sensory profiles of cider vinegars from Korea (K1-2), China (C1-2), Japan (J1-2), and US (U1-2). SPME-GC/MS detected acetic acid as the common volatile compound in all vinegars, in addition to isovaleric acid, octanoic acid, and phenethyl acetate. Acids and acetic esters were the major components of Korean and US vinegar samples, respectively. Chinese vinegars had high ethyl acetate content, while Japanese samples were characterized by a low content of acetic acid. Principal component analysis (PCA) pattern provided a clear categorical discrimination of Chinese vinegars by E-nose and E-tongue analyses. The instrumental sensory scores and the taste attributes for flavor ($r^2=0.9431$), sourness ($r^2=0.9515$), and sweetness ($r^2=0.8325$) were highly correlated. Therefore, SPME/GC-MS, E-nose, and E-tongue analyses may be useful tools to discriminate the sensory profiles of cider vinegars of different origins.

Incheon port attained two million TEU of container throughput between 2013 and 2014 as a third port in domestic container throughput. It opened a new port in Song-do, Incheon in June 2015 to prepare for the continuing increase in container throughput.Therefore, it has provided the platform for being the major container port domestically and internationally. As the role of the new port increases, the role and direction of the Incheon port liner service network attracts attention. This study analyzes the centrality of the Incheon port liner service network by using SNA (Social Network Analysis), which was introduced in the maritime economics area recently, focusing on the Incheon port liner service network. We recognize the degree centrality, closeness centrality, and betweenness centrality of each port and its effect on the Incheon port liner service network. The study showed that for Incheon port, the centrality of the Busan port in Korea, and the Hong Kong port, is high outside the country. This helps us determine that the hub of the Incheon port is neither Shanghai nor Singapore, which ranks first and second, respectively, on container throughput. It is also helps us to know that eastern China's ports have not played a role of the hub of the Incheon port until now because of the relatively low centrality of eastern China's ports.

This research was carried out to investigate the history and development process of the Bansu(泮水) which appeared uniquely at the Chinese 'temple-school(廟學)', Confucian schools as the common and necessary facility through the literature reviews and field surveys. The earliest record about the Bansu was shown in "The Book of Odes(詩經)". Originally Bansu was the water system which flowed near the 'Banpalace(泮宮)', but, in the following time, Bansu has become the symbol of the school which was built by the feudal lords and a very important element in the temple-school landscape. Temple-schools were started at Song(宋) Dynasty and at that time there was no certain form of Bansu, just the natural water course near the structure. Until Ming Dynasty, the "Picture of the Feudal lords' Ban-su" in the book "Samjedohoe(三才圖會)" that compiled by Wang-Xi(王圻), the form of Bansu was appeared to be transformed as the half-round pond. And the half-round pond as called Banji(泮池) of today's form was all rebuilt after Ming Dynasty. The half-moon pond appeared at the private houses, shrines, temples and villages were influenced by the book. From this research we can get the conclusions that Banji seemed one of the sacred one and used in the space arrangement formally for the various functions. This research has found the cultures of half-moon ponds which were used uniquely in China.

Confucius, whose life coincided with the Warring States period of China, is one of the most respected sages in world history whose teachings and life produced countless disciples in China, Korea, and Japan. There are innumerable pictures, sculptures, and other artworks that portray memorable deeds of Confucius and interesting anecdotes that involve his pupils. One of the most popular subjects for these Confucian portrayals is the anecdote in which Confucius and his pupil, Zhi Ru, discover a tilting vessel at an ancestral shrine in the Lu dynasty and use it to understand the doctrine of the mean. The vessel becomes the basis for the famous Chinese expression, "the cautionary vessel beside one's seat," which is nowadays used to denote one's motto for life. Portraits of these tilting vessels can be divided between those showing the vessels only and others that show Confucius observing the vessels. The former serve as visual reminders, for rulers and policy makers, of the doctrine of the mean that is necessary to fair and righteous governance. The latter form part of the pictorial biography of Confucius with educational content and messages. Interestingly, portraits of Confucius observing or studying tilting vessels have been famous among members of the royal court and the literati, circulated either as single artworks or included in the folding screens of human portraits. Portrayals of other Confucian anecdotes are mostly found in albums that visualize the genealogy of the Way; in contrast, the portraits of Confucius and the tilting vessels were included in folding screens that were popular among the literati that enjoyed stylish works of art and antiques. The portraits of tilting vessels thus highlight the diverse functions and symbolic value of human portraits. This study classifies the portraits of tilting vessels into various forms, and analyzes the period-and objective-dependent changes and characteristics in these portraits. With its exploration of the diverse functions and aspects of portraits of Confucian anecdotes, this study will shed new light on how ancient artists reanimated the lives of great sages and how these artworks differ in their expressions and styles.

During the China's long history, many ethnic groups have developed their own traditions of local music which is an important part of their precious cultures. Meanwhile, each ethnic group developed its own worldview and music culture according to its unique living environment, special lifestyle and mode of production. The clarinet is a Western instrument, and has been influenced to some extent by Chinese minority culture while being introduced to China. Therefore, musicians tried to find ways of using Western musical instruments to express various elements of Chinese minority music. Focusing on two clarinet works 'The Song of Grazing Horses' by Wang Yan and 'The Sound of Pamir Clarinet Concerto' by Hu Bijing, this paper aims to analyze the musical characteristics of minority groups expressed by the clarinet in two aspects: the formation of the music style, the artistic characteristics conveyed through the works. Specifically, it consists of five parts: ethnic mode and tonality, rhythm, time signature, melody making, and imitation of animals. It also analyzes the cultural characteristics of Tajik and Mongolian music reflected in the two works in combination with living environment, mode of production, life style, and ethnic emotions. This study aims to provide a theoretical basis for composers and performers who want to understand and acquire the musical style of modern Chinese clarinet works. It also helps to find a better way to play traditional Chinese music with Western instruments.

This study focuses on the analyzing historical and cultural resources formed during the Goryeo, Chosun, and Anti-Japanese Movement periods after the Silla period with the aim of finding ways to utilize its cultural contents. The viewpoint of analysis was made from the perspective of exchange, naturalization, and faith, and the following conclusions were obtained from the analysis. First of all, from the exchange perspective, the activities of Choi Chi-won, Seogyu, and Song Young-gu contributed to the formation of regional historical and cultural contents, such as leaving a lot of ruins or geographic stories in the area and a heritage of good human exchange. From the point of view of naturalization, Du Kyung-ryeong, Cheon Man-ri, and Jeong Yul-seong contributed to the history and culture of the story and the formation of heritage by doing such as contributing activities to the war, anti-Japanese movement for the nation, and the formation of the nation. The most representative from a religious point of view is the Guan Yu faith, which has become a faith believed by the authorities and civilian as a brave longevity and a symbol of the victory of war. The related symbols, paintings, etc. also are objects of worship and have become valuable local Chinese cultural resources as artistic values. Therefore, from a cultural point of view, there is a need to further develop and utilize these China-related historical and cultural resources as good cultural contents by elaborating their stories and local festivals, book culture branding, international music festivals, and exploring various cultures such as Chinese tour courses.
