In this paper, we investigated the affective components of facial beauty. In study 1, we did factor analysis of affective evaluations of the faces, and about 65% of the variances are explained by only two factors. Two factors were named 'sharp' and 'soft', respectively. In study 2, the correlation between facial beauty and affective evaluations was analyzed, and the correlation between facial beauty and sharp factor was significant. In study 3, we made the new images by morphing and warping the faces: 'average', 'high-ranked', and 'exaggerated'. The participants evaluated the 'high-ranked' face more beautiful than the 'average' face, and the 'exaggerated' face more beautiful than the 'high-ranked' face. The rating of affective words on the faces showed that the 'average' face was related to 'soft' impression, the 'high-ranked' image to 'sharp' impression, and the 'exaggerated' face might have double impression. These results might support the directional hypothesis for the facial beauty.

This study was conducted to observe the changes in trend of a beautiful face defined in different time frames. Affective space model was used in this study, for physical components of a face are far too complicated and undistinguishable from simple categorization of a face by facial characteristics. It is because using a facial model defined only by its physical characteristics renders a complicated and multi-dimensional space, whereas an emotional facial model enables a 2-dimensional space for easier observation and explanation. Scope of the study is focused on faces of the Korean female celebrities, looking at the media frequency, popularity rankings in well-known portal sites, and popularity ratings by reliable search organizations as of 2006. Celebrities in their 20s and early 30s were selected. In addition, to observe any trend in a beautiful face with the passage of time, the study looked at changes or trends in the last 5 years by comparing the faces of celebrities in year 2006 with their faces stored in the database since five years ago.

In this paper, Mel-Frequency Cepstral Coefficient (MFCC), Decorrelated Filter Bank (DFB), Octave-based Spectral Contrast (OSC), Zero-Crossing Rate (ZCR), and Spectral Contract/Roll-Off are combined as a set of multiple feature-vectors for the music genre classification system based on the Support Vector Machine (SVM) classifier. In the conventional system, feature vectors for the entire genre classes are normalized for the SVM model training and classification. However, in this paper, selected feature vectors that are compared based on the One-Against-One (OAO) SVM classifier are only used for normalization. Using OSC as a single feature-vector and the multiple feature-vectors, we obtain the genre classification rates of 60.8% and 77.4%, respectively, with the conventional normalization method. Using the proposed normalization method, we obtain the increased classification rates by 8.2% and 3.3% for OSC and the multiple feature-vectors, respectively.

본 논문은 TDX-10 전자 교환기에서 호의 접속과 진행에 사용되는 R2 MFC 신호, DTMF 신호, 연속성 시험음(continuity check tone) 및 가청 신호음(audible tone) 등의 신호서비스 기능을 제공하기 위한 범용형 신호서비스 장치에 관한 것이다. TDX-10 전자 교환기내에서 신호서비스 기능을 효율적으로 제공하기 위한 범용형 신호서비스 장치를 구성함에 있어서, 먼저 호 접속시의 교환동작과 신호 절차 및 신호종류를 살펴보았고, 고려되어야 할 설계원칙들을 고찰하였으며, 이에 따라 구현된 TDX-10 전자 교환기용 범용형 신호서비스 장치의 구성기술과 제반 특징 등에 대해서 기술하였다

저염양념젓갈은 재래식 고식염 젓갈과는 달리 저염, 저온으로 숙성한다는 것이 가장 큰 특징 이며 숙성기간 중 자가소화 및 미생물이 생산하는 효소 작용에 의하여 특유의 감칠맛을 가지게 된다(Park et al., 1996). 기존의 창란젓갈 숙성공정은 0$\pm$2$^{\circ}C$에서 50~60일 동안 정치상태로 숙성하게 되는데(Han, 1996; Park, 1998), 이때 숙성용기 아랫부분에 기체가 발생하는 등 (Kim et al., 1993) 상하간의 품질편차가 크고 숙성기간이 장기화되는 단점이 있다. (중략)

The purpose of this study is to present the direction of career education by analyzing the meaning of the 3rd Five-Year Basic Plan for Career Education (2023-2027). The meaning of the 3rd Five-Year Basic Plan for Career Education (2023-2027) is: First, the 1st Comprehensive Career Education Plan (2010-2013) and the 2nd Five-Year Basic Plan for Career Education (2016-2020) It is most meaningful that the achievements and limitations of the program were analyzed and reflected in the 3rd 5-year basic plan for career education (2023-2027). Second, the career education presented in the 2022 revised curriculum is faithfully reflected. Third, the range of career education has not only increased, but also has been expanded in depth. Based on this, the direction of career education is presented. First, career education needs to be carried out throughout life. Second, it is necessary to respond sensitively to rapid social environment changes. Third, career education needs to be conducted in an organic relationship between government agencies. Career education policies need to be established and implemented from a holistic perspective of various government agencies such as industry, labor, and education.

A novel characteristic value extraction method based on mathematical morphology is proposed. Morphological spatial frequency defined by morphological pattern distribution function is introduced and applied to define a new feature called ‘average height.' The average height is used to define a characteristic value which is to be used to generate an index key value for content-based image retrieval. Superiority of the method was proved for various images by experiment. Furthermore the fact that the proposed method does not need threshold to obtain binary image provides its applicability to content-based image retrieval.

In this paper, a improved method of digital image analysis required in basic medical science for diagnosis of cells was proposed. The object image was the thyroid gland cell image, and the purpose was automatic discrimination of three classes cells(normal cell, follicular neoplastic cells, and papillary neoplastic cells) by difference of chromatin patterns. To segment the cell nucleus from background, the region segmentation algorithm by edge tracing was proposed. And feature parameter was obtained from discrete Fourier transformation of image. After construct a feature sample group of each cells, experiment of discrimination was executed with any verification cells. As a consequency of using features proposed in this paper, get a better recognition rate(70-90%) than previously reported papers, and this method give shape to get objectivity and fixed quantity in diagnosis of cells, The methods described in this paper be used immediately for discrimination of neoplastic cells.
