Phlegmasia cerulea dolens (PCD) is one of the most critical disorders of acute deep vein thrombosis in that it can cause permanent disability secondary to the compartment syndrome. Although several etiological factors have been proposed, PCD after coronary artery bypass surgery is extremely rare and its definitive pathophysiology is still under debate. We herein present a case of PCD that resulted in the compartment syndrome after coronary artery bypass surgery. Early recognition and decompression of PCD are crucial for saving the affected limbs.

This paper aims to develop the learning contents of PBL based program and analyze the result of evaluation questionnaire to examine the students' thoughts concerning the effectiveness of PBL course and their satisfaction. 'Discussion' is one of the representative communicative types, especially requesting both communication competence and teamwork among team members. This study was conducted with 218 junior and senior students taking lectures of ${\ll}$Presentation and Debate Skills${\gg}$ in the college of engineering at Pusan National University. According to the evaluation result, students experienced various effects of PBL such as (1) self-directed learning, (2) cooperative learning, (3) problem solving skills, etc. Students pointed out also as merits of PBL course, (1) knowledge acquisition and information sharing among students, (2) improvement of communicative competence, (3) amelioration of teamwork, (4) progress of the problem solving skills. However, there have been several difficulties and problems during PBL process, implications for ameliorating PBL based were discussed and suggested in detail.

Several distinct pathologic entities are encompassed in benign vocal fold lesions, including intracordal cysts, vascular ectasia, as well as vocal fold nodules and vocal fold polyps. Treatment options for theses lesions include both medical/conservative and surgical techniques. First approaches should be focus on correcting the underlying causative factors, largely through voice therapy and education. There are several laryngomicrosurgery techniques for removal of benign lesions. Much debate continues regarding the relative merits of cold instruments versus carbon dioxide laser removal of benign vocal fold lesions. Both techniques have the merits and the demerits each other. Therefore the surgeon should well comprehend the merits of each techniques and choose the proper procedure for patient's lesions.

Pustejovsky (1995) rekindled debate on the dual problems of how to represent lexical meaning and on the information that is to be encoded in a lexicon. For natural language processing such as machine translation, these are important issues. When a lexical-conceptual mismatch occurs in translation of corresponding words from two different languages, the appropriate representation of their meanings is very important. This paper proposes a new formalism for representing lexical entries by first analysing observable mismatches in comparable pairs of nouns, verbs, and adjectives in English and Korean. Inherent mis-interpretations and mis-readings in each pair are identified. Then, concept theories such as those presented by Ganter and Wille (1996) and Priss (1998) are extended in order to reflect the cognitivist view that meaning resides in concept, and also to incorporate the propositions of the so-called ‘multiple inheritance’system. An alternative to the formalism of Pustejovsky (1995) and Pollard & Sag (1994) is then proposed. Finally, representative examples of lexical mismatches are analysed using the new model.

Interfaces are the point of interconnection between distributed generation and the energy infrastructure. These interfaces are generally physical but can include a market dimension as well. While there are issues surrounding various interfaces, the most important issues in the short term are on the electrical interface. Much of the discussion and debate surrounding distributed generation interconnection has centered on technical issues. However, there are two elements of Interconnection that merit equal consideration-process and contractual issues. The solution of distributed generation Interconnection issues depends on whether existing requirements can be modified to make them more efficient, transparent, and standardized while maintaining the grid's reliability and safety. In this paper, two main courses, standardization and third party participation, are suggested for the resolution of these issues.

Entrepreneurship is considered as an important driver of economic growth, new firm creation, business rejuvenation& job creation. Over a period of time research within entrepreneurship literature has shifted from entrepreneur and his personality to his behavioral disposition. This has led to emergence of entrepreneurial orientation (EO) construct, which focuses on the process of entrepreneurship at firm level and it has emerged as the most widely researched area within entrepreneurship field. Though research in this field has been rigorous and exhaustive, still there have been concerns that researchers might have prematurely agreed on the composition, dimensionality, and nature of EO Construct. There has been considerable debate about whether EO Construct comprises three or five dimensions, about co-variance or independence of these dimensions and nature of construct whether formative or reflective. This article builds an argument about the multidimensional nature of EO construct comprising five dimensions, which vary independently and the fact that EO is better explained through formative construct rather than reflective one.

The objectives of this study are to analyze the railway traffic conditions of Korea, China and Japan, and to appropriate the railway network planning for international logistics in Northeast Asia. Korea is located geographically on the main trunk route in Northeast Asia. Considering the geographical advantage and the overall potential of the economic and trade in Northeast Asia region, this area is required to connect the railway network. Recently, the scale of economic in Northeast Asia, including Korea, China and Japan, is increasing, also Northeast Asia's gross domestic product(GDP) is 22 percent of global and containers trade come up to 36 percent. Each country intend about integration of economic region for activity of mutual economic cooperation, for steady development and prosperity of each country economic all over the world, and Northeast Asia countries are in debate. There is a quite possibility of integration by a single economic region in Korea, China and Japan. Accordingly these countries should have expansion of traffic infrastructure, when the economic region is going to integration.

There is still debate over which method of the surgery is the most appropriate for the treatment of scaphocephalic infants. In addition, change in psychomotor development following these procedures is a very complex issue that has not yet been resolved. In this paper, the authors describe a surgical technique for immediate spontaneous shape correction of infantile scaphocephaly. There were significant differences between pre- and postoperative cephalic index. We also describe an improvement in the developmental quotient following surgery. Therefore, this expantile zigzag craniectomy should be recommended to correct for isolated sagittal craniosynostosis in infants.

This study examines the importance of learning language and cultural integration in general English class focused on TOEIC reading comprehension. The understanding of cultural learning and learners' cultural awareness has long been a subject of debate. This study was not only to analyze the improvement of students' interest and reading comprehension ability of TOEIC through cultural learning, but also to ensure students who learn American culture overcome cross-cultural miscommunication and improve their English reading comprehension skills. Pre-post surveys and the pre-post TOEIC tests were used to measure language proficiency and American cultural knowledge to two groups: the experimental and control group. The results from the study were as follows: First, students had better TOEIC scores with improved motivation after understanding American culture relevant to the lessons. Second, reading comprehension skills with regards to TOEIC also improved, compared with the students who were not exposed to American culture due to lack of opportunity.
