As the digital technology has improved, the numbers of Hangul font users have increased and their individual needs and taste are diversified. Therefore new and various Hangul fonts out of traditional form are developed and used. But under the present font classification system, it is hard to compare and analyze these various fonts. And the present classification system is hard to be the font user's guide for proper use of various Hangul fonts. For the better use of Hangul font, to diversify the font classification system is needed. So we propose the development of these thru classification standards. First, structural classification based on the structural character of Hangul. Second, image classification based on the visual images of each font. And third, usage classification based on the fonts proper usage in various media. For the development of various typographically balanced fonts and for the suitable and effective use of the various font, we must try to build the font classification system based on the diversified classification standards and build Hangul font database based on this classification system. Through these studies, we can expect the development of good quality fonts and the better use of these fonts.

Common factor analysis and principal component analysis represent two technically distinctive approaches to exploratory factor analysis. Much of the psychometric literature recommends the use of common factor analysis instead of principal component analysis. Nonetheless, factor analysts use principal component analysis more frequently because they believe that principal component analysis could yield (relatively) less accurate estimates of factor loadings compared to common factor analysis but most often produce similar pattern of factor loadings, leading to essentially the same factor interpretations. A simulation study is conducted to evaluate the relative performance of these two approaches in terms of factor pattern recovery under different experimental conditions of sample size, overdetermination, and communality.The results show that principal component analysis performs better in factor recovery with small sample sizes (below 200). It was further shown that this tendency is more prominent when there are a small number of variables per factor. The present results are of practical use for factor analysts in the field of marketing and the social sciences.

Purpose: This research was designed to figure out if there are changes based on types of vergence fixation disparity curve after optical correction and vision training to for people with steep slope of forced vergence fixation disparity curve and symptoms. Methods: For 30 subjects out of 91 subjects, who have steep slopes of fixation disparity curve examined with Wesson Fixation Disparity Card and symptoms about steep slope of fixation disparity curve, proper vision training was offered for 5 weeks. Results: After Vision training for 30 people with the symptoms of type I, II, III, IV for 5 weeks, slope of fixation disparity curve was significantly changed (p=0.013), and the results of binocular vision test and subjective symptoms were also significantly improved. Conclusions: Vision training can not only affect the change of fixation disparity curve, but also relieve the symptoms. Fixation disparity curve has lots of visual function information of the subject and can be suggested as a guideline for prescribing.

최근 전자 소자의 고주파화, 소형화에 대한 요구가 증대 되면서 많은 소자들을 하나의 시스템에 3차원적으로 실장시키는 SOP (System-on-Package)가 새로운 대안으로 떠오르고 있으며 SOP를 실현하기 위해서는 집적기판에 대한 저온화 공정 기술이 절실히 필요한 실정이다. 현재 집적기판에 사용되는 재료로서 세라믹이 널리 알려져 있지만 세라믹은 취성이 있으며 $1000^{\circ}C$ 이상의 고온화 공정 프로세스를 필요로 하는 근본적인 약점이 있다. 이에 본 연구에서는 상온에서 고속으로 치밀한 성막을 가능케 하는 Aerosol Deposition Method (ADM)를 이용하여 최초로 세라믹-폴리머 복합체 후막을 성공적으로 제작하였다. XRD와 FT-IR 분석 결과 $Al_2O_3$-PMMA, $Al_2O_3$-PI 혼합물을 출발 파우더로 사용하여 제조한 후막이 세라믹-폴리머 복합체임을 확인할 수 있었다. 또한 SEM 분석결과 $Al_2O_3$-PMMA 복합체와 $Al_2O_3$-PI 복합체의 표면 양상이 매우 다르다는 점을 확인하였으며 $Al_2O_3$-PMMA 복합체의 성막률이 $Al_2O_3$-PI 복합체의 성막률에 비해 매우 낮음을 확인하였다. 이러한 현상들은 폴리머 파우더들의 경도와 탄성 차이 때문인 것으로 사료되어 이를 증명하기 위한 실험을 실시하였다. 결국 PMMA 막과 PI 막에 대한경도측정결과와 PMMA 파우더와 PI 파우더의 유성 볼밀링 전후에 대한 SEM 이미지를 통해 PMMA 파우더가 PI 파우더에 비해 경도가 낮으며 반면 탄성이 높다는 것을 간접적으로 확인할 수 있었다. 이와 같은 분석을 통하여 ADM을 이용한 세라믹-폴리머 복합체 후막의 제조에 있어 폴리머 파우더의 경도와 탄성이 매우 큰 영향을 미친다는 것을 알 수 있었다. 본 연구에서는 세라믹-폴리머 복합체 후막을 성공적으로 제조하기 위해서 폴리머 파우더의 적절한 선택이 중요함을 알 수 있었으며 ADM을 이용한 세라믹-폴리머 복합체 후막의 제조에 대한 가이드 라인을 제시할 수 있을 것으로 기대된다.

To protect financial services against danger of financial accidents and customer information leakage caused by malware, injection attack and so on, Financial Services Commission announced "Financial Networks Security Enhancement Comprehensive Plan", which suggests the guideline of protecting customer information and providing secure financial services by separating network topology and then makes the financial company use network partitioning system. In consequence of this policy, financial companies respectively chose between the physical partitioning mechanism or the logical partitioning mechanism according to their IT environment. This paper suggests an efficient infrastructure configuration plan for making the logical network partition, by comparison of a construction of traditional general equipment and an integrated HCI(Hyper Converged Infrastructure) through 'Hyper Converged' which is one of virualization techniques for developing currently, and the case study of the integrated HCI method.

Until now, a variety of the standard and research activities are progressed in the business process management. However, since the common standard of the collaboration process language has not been determined, the research activities could not be well-systemized. We would present the guide-line to select and use the collaboration process language straightly through comparing different collaboration process languages (BPEL4WS, BPML, WSCI, WS-CDL, BPSS, etc). In this regard, we define the implicit and the explicit collaboration as the collaboration method in advance and present the result acquired according to compare and analyze the features of the collaboration process languages. First, the necessary elements the collaboration process languages have are extracted through the framework of the inter-organizational workflow proposed by Bernauer and the collaboration process modeling procedure(CPMP). Second, we analyze the properties of the collaboration process language based the essential elements. Finally, we show the complete example that the collaboration business process really reflects the characteristics of the collaboration business process languages

Verification, Validation & Accreditation (VV&A) process is widely applied in various disciplines as a method of acquiring the credibility for M&S tools. The guideline of VV&A states that the detailed process can be established flexibly according to the needs and the availability of resources. For example, DAPA (Defense Acquisition Program Administration) guideline suggests that the accreditation process in the VV&A can be omitted if necessary. On this study, we first introduce and describe V&V process. Accreditation process is omitted due to limited time and resources. However, the proposed V&V is sufficient for our needs. Finally, we apply the proposed process of V&V to the System-Integrated Simulator of "Raybolt", Medium-Range Infantry Missile System, for the acquisition of the M&S credibility.
