This study aims to evaluate and identify the patterns of the technological competitiveness of the Korean industry. Such statistics as R&D expenditure and R&D manpower as input indexes, US patent registrations and export sales as output indexse were used. It was turned out that such industrial types as specialized-suppliers industries, scale-intensive industries and science-intensive industries showed relatively strong technical competitiveness. However, resource-intensive industries and labor-intensive industries which had maintained a competitive advantage in the 1970s and the 1980s appeared to be gradually losing their technological competitiveness. These results are by and large in accordance with the trends of export performance. This study conducted the canonical discriminant analysis in order to test the correctness of the patterns displayed in the technological competitiveness of the Korean industry. The result of the analysis showed that the five patterns of technical strength of the Korean industries are significantly independent each other for four respective variables which are used to distinguish industries. This implies that the ex ante industrial classification into five types was correct in terms of the ex post statistics, and that the patterns of technological competitiveness discovered in this study are also statistically correct.

The purpose of this study is to correctly understand the shapes and transformation of costumes of Ching's and Mongolian. Mongolian traditional costumes are trousers and jacket, with Deel(袍) and Terlig(帖裡) pleated in the waistline, and knee-covering narrow-sleeved long dress for men and women alike. It was designed for adapting to horse riding activities and cold steppe climate. Similarity between Ching's and Mongolian nomadic costumes was used as a means of unity by Ching. Transformation of Mongolian nomadic costumes are further divided into three kinds; Ching's or Russian's details applied to Mongolian nomadic costumes(Taekeum(大襟), Majesu(馬蹄袖), white choker), Ching's court costume imported as it is for the political purpose(Kijang(기장)), resistance against foreign countries and the spirit of nomadic people and independence reflected in Mongol costumes('Teregur ushi', 'Correct bosom'). Specially, Nomadic symbols constitute Mongolian spiritual world and clothing habits, especially evident in ladies' dresses.

As long as the prognosis of teeth remains a matter of concern, the endodontic-periodontal relationship will be considered a challenge for the clinician. Many etiologic factors, including bacteria, fungi, and viruses, plus other contributing factors, such as trauma, root resorptions/perforations, and dental malformations, play a role in the co-occurrence of endodontic and periodontal lesions. Whatever the cause, a correct diagnosis on which to base the treatment plan is the key to successful maintenance of the tooth. This article reports the successful endodontic management of a furcation lesion in a mandibular molar that was nonresponsive to a previous periodontal surgical graft. The case had presented a diagnostic challenge for the clinicians, and this article reviews the key points that can lead to a correct diagnosis and treatment planning.

This study aimed to investigate how EFL learners perceived English writing tasks and teachers' written feedback. The subjects were 82 mixed major college EFL students aged 19-24; the majority were freshmen females. Based on the scores estimated from the essay evaluation test, they were placed into two groups (proficienand less-proficient writers) and responded to an in-class questionnaire. The results indicated that: (1) regardless of writing proficiency, a large number of the students felt that they were just fair writers, which could be derived from low confidence and high anxiety; (2) grammar and vocabulary were perceived as the main features that determined good EFL writers and also prevented the students from performing the writing task successfully; (3) they believed that teachers' feedback contributed to the development of their English writing skills because it helped them apprehend what to improve or avoid in the future, acquire better English usage, and correct their errors; and (4) the proficient writers were more willing to correct errors themselves after being provided clues than the less-proficient writers. Implications of the findings for EFL classrooms are discussed.
