  • This article discusses the validity of selective/unilateral arbitration agreement that provides arbitration as one of several dispute resolution methods. The Supreme Court has held selective/unilateral arbitration agreement that is conditional invalidity since the judgement of 2003Da318 decided on Aug. 22, 2003: In the following judgements of 2004Da42166 decided on Nov. 11, 2004 and 2005Da12452 decided on May 27, 2005, the Court stated that the selective/unilateral arbitration agreement that stipulates to resolve a dispute through arbitration or mediation would be valid as an effective arbitration agreement only if a party elects and proceeds an arbitration proceeding and another party responses to the arbitration proceeding without any objection. The definition of arbitration agreement, the formation of selective/unilateral arbitration agreement, the summary of relative judgements and academic theories will be reviewed in order to examine the appropriateness of the series of judgements of the Supreme Court. Based on such reviews, this article will investigate the adequacy of the Supreme Court judgements from the perspectives of i) the principle of party autonomy, ii) the structure of dispute resolution methods, iii) legal provisions of Arbitration Act, iv) legal stability, and v) the policy to revitalize the use of arbitration. At conclusion, this article will suggest the change of precedents of the Supreme Court's judgements with regard to the selective arbitral agreement.

  • 이 논문은 1922년부터 1944년까지 열렸던 조선미술전람회에 대한 신문보도의 내용을 분석하여 그 특성을 파악한 것이다. 조선미술전람회는 일본의 식민지배하에 있는 조선 미술의 낙후성과 미개함을 강조하고, '지방색'만을 강조함으로써 식민지 조선의 '열등한 정체성'과 일본의 '우월한 정체성'을 차별적으로 확인하게 만드는 수단이 되었다. 아울러 서양은 발전된 현재이고 동양은 과거에는 발전했으나 현재는 정체된 것으로 바라보는 오리엔탈리즘의 기본 시각이 재현되어 조선의 미술문화를 쇠락(衰落)한 지방문화쯤으로 치부하고 있다. 일제하 총독부 신문이었던, 매일신보에 대한 담론 분석결과 한편으로는 식민지 조선을 중앙(일본)의 연장선상에 있는 '지방(내지)'으로 편입하는 '동화주의적' 측면을 가지면서도, 다른 한편으로는 근대화된 일본과는 구분되는 미개한 일개의 '지방(외지)'으로 차별화하는 '배제주의적' 측면을 갖고 있었다. 동아일보의 경우 오리엔탈리즘적인 시각에서 벗어나지 못하면서도, 조선 미술의 자존심을 지키려는 방식으로 기사를 구성했다는 점에서 혼종적인 보도 태도를 보이고 있었다.

  • An odontogenic cutaneous fistula is a pathological communication between the outer skin surface of the face and the oral cavity. Facial cutaneous fistula is a complication of odontogenic infection that is often misdiagnosed with skin infection. We report a rare case, which was diagnosed as basal cell carcinoma based on the biopsy of skin lesions in the patient who had been diagnosed with odontogenic cutaneous fistula. A 64-year-old male patient presented with a cutaneous odontogenic fistula. The patient had undergone surgical extraction of fistula tract and loose tooth before dermatology or plastic surgery consultation. With the biopsy and computed tomography, it was confirmed that fistula and basal cell carcinoma. However, the connection between the fistula and skin cancer was not clear. Positron emission tomography-computed tomography scan was performed and was not detected as other local or distant metastasis. After that, wide excision of the skin lesion was performed. Although skin cancer is not commonly observed, it is necessary to rule out this disease entity by performing biopsy of skin lesions.

  • Background: Closed reduction is the standard treatment for nasal bone fractures, which are the most common type of facial bone fractures. We investigated the effect of closed reduction on quality of life. Methods: The 15-dimensional health-related quality of life survey was administered to 120 patients who underwent closed reduction under general anesthesia for nasal bone fractures from February 2018 to December 2019, on both the day after surgery and 3 months after surgery. Three months postoperatively, the presence or absence of five nasal symptoms (nose obstruction, snoring, pain, nasal secretions, and aesthetic dissatisfaction) was also evaluated. Results: The quality of life items that showed significant changes between immediately after surgery and 3 months postoperatively were breathing, sleeping, speech, excretion, and discomfort. Low scores were found at 3 months for breathing, sleeping, and distress. There were 31 patients (25.83%) with nose obstruction, 25 (20.83%) with snoring, 12 (10.00%), with pain, 11 (9.17%) with nasal secretions, and 29 (24.17%) with aesthetic dissatisfaction. Conclusion: Closed reduction affected patients' quality of life, although most aspects improved significantly after 3 months. However, it was not possible to rule out deterioration of quality of life due to complications and dissatisfaction after surgery.

  • Ghrelin is a novel growth-hormone-releasing acylated peptide, which has been purified and identified in rat stomach. In the present study, the full-length sequence of bovine ghrelin cDNA was cloned by RT-PCR. The bovine ghrelin cDNA sequence derived in the present study included a 348 bp open reading frame and a 137 bp 3'UTR. The putative amino acid sequence of bovine prepro-ghrelin consisted of 116 amino acids, which contained the 27-amino acid ghrelin. The sequence analysis of the bovine ghrelin gene revealed that an intron existed between Gln$^{13}$ and Arg$^{14}$ of ghrelin. This exon-intron boundary matched the GT-AG rule of the splicing mechanism. Compared with rats, which have two tandem CAG sequences in the 3'end of intron, bovine ghrelin genome has only one CAG sequence. Therefore, although rats can produce 28 amino acid-ghrelin and 27 amino acid-des-Gln$^{14}$-ghrelin by alternative splicing, ruminant species, including bovines, might be able to produce only one type of ghrelin peptide, des-Gln$^{14}$-ghrelin. The influence of aging on plasma ghrelin concentration was also examined. Plasma ghrelin concentration increased after birth to approximately 600 days of age, and then remained constant.

  • Mammal microsomal glutathione transferase 1 (MGST1) can conjugate many toxic or carcinogenic substances and depress oxidative stress. In this study, Chicken MGST1 and its variants were cloned for the first time and were composed of 956 or 944 nucleotides. The 12 nt deletion in the exon 2 did not alter the GT-AG rule and the ORFs for the two MGST1 variants were the same, which both comprised 465 nucletides and encoded a peptide with 155 amino acids. It was found that the two different splice variants identified using RT-PCR expressed in all three organs investigated of Dwarf Brown Chicken, namely liver, spleen and shell gland. Moreover, the expression level of MGST1 mRNA in the liver of Dwarf Brown chickens was the highest (p<0.01), and there were no significant differences between the spleen and the shell gland. These results provide a base for studying the biological function of Chicken MGST1.

  • This essay interrogates the category of the 'global' in the emerging domain of 'global intellectual history'. Through a case study of the Indian social-religious reformer Rammohun Roy (1772/4-1833), I argue that notions of global selfhood and rights-consciousness (which have been preoccupying concerns of recent debates in intellectual history) have multiple conceptual and practical points of origin. Thus in early colonial India a person like Rammohun Roy could invoke centuries-old Indic terms of globality (vishva, jagat, sarva, sarvabhuta, etc.), selfhood (atman/brahman), and notions of right (adhikara) to liberation/salvation (mukti/moksha) as well as late precolonial discourses on 'worldly' rights consciousness (to life, property, religious toleration) and models of participatory governance present in an Indo-Islamic society, and hybridize these with Western-origin notions of rights and liberties. Thereby Rammohun could challenge the racial and confessional assumptions of colonial authority and produce a more deterritorialized and non-sectarian idea of selfhood and governance. However, Rammohun's comparativist world-historical notions excluded other models of selfhood and globality, such as those produced by devotional Vaishnava, Shaiva, and Shakta-Tantric discourses under the influence of non-Brahmanical communities and women. Rammohun's puritan condemnation of non-Brahmanical sexual and gender relations created a homogenized and hierarchical model of globality, obscuring alternate subaltern-inflected notions of selfhood. Class, caste, and gender biases rendered Rammohun supportive of British colonial rule and distanced him from popular anti-colonial revolts and social mobility movements in India. This article argues that today's intellectual historians run the risk of repeating Rammohun's biases (or those of Hegel's Weltgeschichte) if they privilege the historicity and value of certain models of global selfhood and rights-consciousness (such as those derived from a constructed notion of the 'West' or from constructed notions of various 'elite' classicized 'cultures'), to the exclusion of models produced by disenfranchised actors across the world. Instead of operating through hierarchical assumptions about local/global polarity, intellectual historians should remain sensitive to and learn from the universalizable models of selfhood, rights, and justice produced by actors in different spatio-temporal locations and intersections.

  • Global Electronic Trading means that trading partners trade each other via Global Electronic Trading Network, that is, global business to business electronic commerce. Recently, where the cargo arrives ahead of the B/L, the importer cannot take delivery of the cargo without the B/L. This situation is referred to as the B/L dilemma. But the BOLERO system will resolve this B/L dilemma. Bolero Project is developing a cross industry utility platform for the secure, electronic transfer of commercial trade information world wide. After the successful testing of an original pilot project, The Bolero Association was formed in 1995 by a group of interested cross industry companies. As a joint venture between SWIFT and TT Club, bolero.net is changing the way the world trades by providing a web-based, paperless mode of commerce that is designed to become a global standard. Bolero International Limited published the first edition of Bolero Rulebook in 1999. The Bolero Rulebook as amended from time to time, governing the relationship between Users and their rights and obligations arising from the Bolero system. The Bolero service will be governed by a multilateral contract called the Bolero Rule Book which specifies the rights and responsibilities of Bolero and its users. The Title Registry and Bolero Bill of Lading provide a fully functional equivalent to the paper bill of lading. The Bolero Bill of Lading can be created, transferred, amended, and surrendered by way of designating to order party, blank endorsement, refusal by the transferee etc. Thus, this study deals with the functions of Bolero Bill of Lading and the problems and solutions in the Bolero Bill of Lading in point of definitions and operation under the Bolero Rulebook.

  • Adjusting pressure level in the construction of athletes' tight-fitting garments by reducing the elastic knit pattern is a challenging subject, which influences the performance of the wearer directly. Therefore, in this study, relationship between the reduction rates of the basic pattern obtained from 3D human scan data and resultant clothing pressure was explored to improve the fit and pressure exerted by clothing. 3D scan data were obtained using Cyberware and they were transformed into a flat pattern using software based on Runge-Kutta method. Reduction rate was examined by subjective wear test as well as objective pressure measurement. As a result, difference in the length between the original 3D body scan data and the 2D tight-fitting pattern was 0.02$\sim$0.50cm (0.05$\sim$1.06%), which was within the range of tolerable limits in making clothes. Among the five garments, the 3T-pattern was superior in terms of subjective sensation and fit. The pressure of the 3T pattern was 2$\sim$4 gf/cm2 at five locations on the body, which is almost the same or a bit higher than that of Z-pattern. In the case of tight-fitting overall garment, the reduction rate of the pattern in the wale direction is more critical to the subjective sensation than the course direction. It is recommended that the reduction grading rules of course direction should be larger than that of Ziegert for a better fit of tight-fitting garments. In the case of wale direction, however, reduction grading rule should be kept the same as suggested earlier by Ziegert (1988).
