This study attempted to publicize the excellence of art of seal engraving in the Joseon Dynasty by analyzing the fusion factors of seal 'Wandangyego' which Oh Gyuil engraved. The appearance of Wandangyego was compared with other seals. The calligraphy philosophy in Wandangyego, the composition of inmun Wan-Dang-Ye-Go, and Oh Gyuil's method of holding graver were analyzed. As a result, Wandangyego was the world's largest rectangular seal and contained the writing philosophy of his teacher Kim Junghee. Oh Gyuil was a seal engraving artist and expert in the manufacture of seal handles. He used 'chungdo' and 'jeoldo' appropriately, and stimulated the deliberate emotion of oriental art with layout applied with exquisite oriental golden ratio. The importance of the real seal was suggested, and it was proved that the seal Wandangyego was a prominent work worldwide. The results of this study are expected to be a new research methodology for analyzing the fusion factors in painting, sculpture and design.

This paper examines the studies and its tendency on Japanese Confucianism Research from 2007 to 2009 in Korea. In recent years, Japanese confucianism studies in Japan, China and Taiwan have been introduced to the academic society of Korea. And many scholars who major in Japanese thought have been invited to Korea and published the results of their research in Korea. Also, there have been researchers who obtained the degrees of Doctor or Master by researching Japanese thought. This paper, lastly, introduced the papers on the Japanese confucianism which were published in Korea during the recent 3 years. If we evaluate all the trend in researching Japanese confucianism in Korea, it can be said that it is still in the early stages. Recently, however a small but significant advance has been acquired. In conclusion, we can expect the future of the Japanese confucianism studies in Korea.

Colloidal gold with a conducting polymer (e.g., polyaniline) bound on the metal surfaces has been used for the generation of conductimetric signal in a membrane strip immunosensor. Since polyaniline itself at a low pH range revealed a low conductivity, an approach of doping the polymer with a lithium salt was used. As an alternative method, a self-doped (i.e., pH-independent) sustance such as leucoemeraldine base sulfonated polyaniline (LEB-SPAN) can be used as signal generator. It was also highly soluble in water and, thus, such a selected polymer was expected to support a satisfactory property as a label of the immunosensor.

W₂C is synthesized through a reaction-sintering process from an ultrafine-W and WC powder mixture using spark plasma sintering (SPS). The effect of various parameters, such as W:WC molar ratio, sintering temperature, and sintering time, on the synthesis behavior of W₂C is investigated through X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM) analysis of the microstructure, and final sintered density. Further, the etching properties of a W₂C specimen are analyzed. A W₂C sintered specimen with a particle size of 2.0 ㎛ and a relative density over 98% could be obtained from a W-WC powder mixture with 55 mol%, after SPS at 1700℃ for 20 min under a pressure of 50 MPa. The sample etching rate is similar to that of SiC. Based on X-ray photoelectron spectroscopy (XPS) analysis, it is confirmed that fluorocarbon-based layers such as C-F and C-F2 with lower etch rates are also formed.

The key concept of political thoughts of Confucianism is 'Tian(天)=the Heaven' and 'Ren(人)=the Human being'. In particular, the meaning of 'the Heaven(天)' is profoundly exclusive in Confucianism in comparison to the other concepts. It is because that 'the Heaven' is connected with 'Ri(理)' which explains the human being and the heaven metaphysically, and the discussions about those concepts have also been widening to the political field. And if the concept of 'the Heaven's nature(天命)' is excluded, it is difficult for us to discuss the essence of political thought of Confucianism. This paper argued how the politicalization of 'the Heaven' which was private dimension of monarch in the strict sense, changed to the public dimension of people in Japan in the early 18th century through some theories of the two famous philosopher, Ito-Jinsai(伊藤仁齋) and Ogyu-Sorai(荻生?徠) who belonged to the 'Kogakuha(古學派)'. The doctrines of Chu-tzu(朱子學) has hold absolute authority over the history of the oriental political thoughts. But the authority have gone through the stage of disorganization in a unique space called Eto(江戶) era of Japan. Therefore, the interpretations and concept establishments in a new dimension are naturally formed in that periods about 'Min(民)=People'. Based on discussions like this, the purpose of this paper is to study how those movements are emerged in what kinds of thinking and debating process. In part of Ito-Jinsai, this paper have reconsidered the concept of 'People' which Jinsai had thought and examined closely with critical mind about 'In(仁)=Mercy'. In case of Ogyu-Sorai, this paper have argued his political theory of 'the welfare of the people in the nation(安民天下)', in clarifying with the concept of 'the Roads of the Saint(先王의 道)' and the meaning about his declaration that "the Six Scripture(六經) is things(物)". The meaning of political view of this two philosopher is in the point to suggest some kinds of cure for problems of those days with the former days values. In the Jinsai's doctrine, that cure is 'the realization of the rule of right(王道)' based on new interpretation of 'Mersy'. And in case of Sorai, that is a form of independence of politics from morality based on 'the Roads of the Saint'.

This thesis to be studied conversation by writing between the medical staff of Chosun(朝鮮) and Japan in 1763. Both countries the medical staff and intellectuals meet that communication, confrontation and conflict, exchanges and cooperation in 18C. They met greeting and sing in chorus. Chosun keep checking in western medicine of Japan. They are compared to customs of two countries. Also Japanese increase interest in the Hangeul(한글). Confrontation and conflict resulted from history recognition and difference of viewpoint of two countries. Especially Kokugaku(古學) have many influence on this situation. So battle come and go to study of Ogyu Sorai(荻生?徠) and Dajai Jun(太宰純). But this situation includes Mutual misunderstanding. Because of limitation on conversation by writing. Exchanges and cooperation take shape on the medical staff that a process of ginseng(人蔘), medical treatment. And two countries promote goodwill that method of buying books in Japan and medical treatment. In conclusion, intellectuals of Chosun and Japan have some misunderstanding and distrust. but they are communication with Chinese writing that east asian's common language. Also exchange its views and information.

Esophageal cancer is easy to infiltrate and metastasize because esophagus does not have serosa, and is difficult to remove it because esophagus is in the middle of the chest. Because of this, treatments of esophageal cancer do not always follow the guideline. In this situation, efforts to increase treatment efficiency and improve survival rate through multidisciplinary treatment are increasing. In this case, we report the patient with three superficial esophageal cancers (one in cervical esophagus and two in thoracic esophagus). The patient was treated with concurrent chemoradiotherapy instead of surgery through multidisciplinary discussion. The patient reached a complete remission through this discussion. This case is intended to inform the usefulness of multidisciplinary treatment in patients with esophageal cancer.

Objectives : The purpose of this study was to investigate the needs for return-to-work support of cancer survivors and related factors in patients with cancer and their caregivers. Methods : 182 patients and 114 caregivers were recruited. Distress Thermometer and Problem List and scale ranging 0~10 measuring the degree of needs for return-to-work support were utilized. The needs for return-to-work support between the patient group and caregiver group (patient's needs evaluated by the caregiver) were compared, and related factors were investigated using logistic regression analysis. Results : 34.6% and 28.1% of patients and caregivers reported return-to-work support of cancer survivors is "very necessary". The degree of needs was 6.60±3.365 points in the patient group and 6.17±3.454 points in the caregiver group, with no significant difference (p=0.282). The needs for return-to-work support evaluated by patients was high when they underwent surgery (OR=2.592, p=0.007), has fertility problems (OR=6.137, p=0.025), has appearance problems (OR=2.081, p=0.041), or has fatigue (OR=2.330, p=0.020). The needs for return-to-work support of patients evaluated by caregivers was high when patients treated with breast cancer (vs respiratory cancer, OR=13.038, p=0.022 ; vs leukemia/lymphoma, OR=4.517, p=0.025 ; vs other cancer, OR=13.102, p=0.019), has work/school problems (OR=4.578, p=0.005), or has depression (OR=3.213, p=0.022). Conclusions : The degree of needs for return-to-work support of cancer survivors was high, and factors related to the needs were different between the two groups. This suggests that return-to-work support of cancer survivors is required, and clinical characteristics, the distress of patients, and differences between patients and their caregivers should be considered in establishing a support plan.
