Along with the development of industrial technology, the product differences are getting narrow in terms of technology nowadays. Most of the enterprises create the differentiation through distinctive and lasting brand personality which satisfies customer needs for symbolic and self-expressive function. Brand Personality becomes a useful method in expressing self-image, and customers are likely to favor the brand with a distinctive personality. Brand personality and self-image can be flexibly in order to develop a marketing strategy and establish a strong brand. This research is based on Aaker’s BPS study(1997) and attempts to find out the influence of congruity between brand personality and self-image on attitude toward brand. First, this study examines the influence of brand personality on brand attitude, and compares the relative effect of various dimensions of brand personality on brand attitude. Second, this study examines the impact of congruity between brand personality and actual/ideal self-image on brand attitude. Third, this research explores the possible moderating role of self-esteem in the relationship among brand personality, self-image and brand attitude. Male sport shoes and female makeups were chosen as the testing products and three major brands in each of the above product categories were selected. The brand personality scales (big five) of Aaker (1997) were used to measure brand personality and self-image, and self-esteem, brand attitude and demographic questions were also measured. For data analysis, I used SPSS statistic package and analysis of frequency, factor, confidence, t-test, multi recurrence and control recurrence. The research objects were the students from Dongguk University, and the research questionnaires were divided into two categories of A and B. Sport shoes are in category A while category B for makeups. The research questionnaires were handed out based on gender in which 94 copies for male students and 124 of female students. The results of this research are as follows: First, brand personality and brand attitude, proved a positive relationship, and various dimensions of brand personality have different influences on brand attitude. Second, the congruity between brand personality and actual self-image proved to have a positive relationship with brand attitude in the whole group and makeups group. And the congruity between brand personality and ideal self-image have a positive relationship on brand attitude in the whole group and each category. In a word, the higher of congruity between brand personality and self-image the better attitude toward the brand. Last, self-esteem's moderating effect was not found on the relationship among brand personality, actual/ideal self-image and brand attitude. which means the higher the congruity of brand personality and self-image the better attitude toward the brand, however, the customer’s self-esteem was not effect their attitude toward a brand.

영상 에지 검출을 위한 2차원 가변 디지털 필터 설계

조운 동국대학교 일반대학원 2022 국내박사

최근에는 웨이블릿 영역에서 직접적으로 간단한 계산을 이용한 에지 필터링 기술이 발전하고 있다. 이 기술은 영상 전체에 연산이 적용되어 빠르게 수행할 수 있는 장점이 있다. 그러나 연산에 쓰이는 웨이블릿 필터 계수가 고정되어 있기 때문에, 작은 노이즈에도 매우 취약한 단점을 갖는다. 또한, 에지와 노이즈를 구분하기가 어렵기 때문에, 끊어진 에지를 강제로 연결하거나 두꺼운 에지가 감지되면 강제로 끊어지는 문제가 있다. 따라서 복잡하고 노이즈에 강건하고 정확도를 높이기 위한 새로운 에지 웨이블릿 필터 설계가 요구된다. 본 논문은 효율적이고 정확한 에지 검출을 위해 가변 2차원 필터링 방법을 설명하고, 영상의 정확한 에지 검출을 위한 효과적인 2차원 웨이블릿 함수를 설계한다. 제안된 방식에서는 고정된 계수를 갖는 1차원 3-tap, 5-tap, 7-tap 웨이블릿 필터를 설계하고, 각각의 주파수 응답을 조절할 수 있는 파라메터를 추가했다. 이를 통해 설계된 1차원 필터를 각각 수평방향, 수직방향으로 배치 후 컨볼루션 연산을 통하여 새로운 2차원 구조의 적응형 에지 검출 필터를 설계 했다. 즉, 독립적인 파라메터의 값 조절을 통해 주파수 응답을 유연하게 변경할 수 있으며, 대상 이미지에 최적화가 가능하고, 기존의 방식보다 나은 성능을 보이는 것을 다양한 영상에 적용하여 실험으로 검증했다. 본 연구는 영상의 중요한 정보를 잃지 않고 정확한 에지를 추출할 수 있기에, 진단의료영상의 병증 검출, 자율주행의 차선 검출, 머신비전의 부품 결함 검출 등에 적용 될 수 있다. Recently, edge-extraction-filtering techniques for the image edge detection have been reported because taking advantage of direct and simple computations in wavelet domain. However, there still remains a serious problem that reduces the accuracy of edge detection by using the non-adaptive wavelet filters. Therefore, a new wavelet filter design is needed to ensure an accuracy of edge detection. This paper describes a noble 2-dimensional(2-D) edge-extraction filtering method for the efficient and accurate edge detection and allows an explicit 2-D wavelet function for the exact edge detection of images. The proposed 2-D wavelet filters are characterized by an adaptively controllable edge-frequency parameter and potentially leads to improved edge detection accuracy (even noisy diagnostic-medical images). It can be concluded that this new approach allows more flexible and affordable edge-detection systems to be built, and it helps solve limited filter-design problems due to obtaining desired 2-D wavelet edge-extraction filters for the exact edge detection of images.

Wong Kar-wai, a representative director of Asian literary cinema, has a particularly strong personal style among Hong Kong film directors. His films all have unique aesthetic atmosphere and functional value. Therefore, the study of Wong Kar-wai’s films is of great significance in the field of image theory and culture. Wong Kar-wai has directed 12 films over 40 years, including various types of female characters. This paper analyzes the femininity by focusing on the cheongsam worn by female characters in Wong Kar-wai’s three films, <In the Mood for Love>, <2046> and <The Grandmaster>. By conducting the literature research and case study, this paper finds out the following results. Like many other traditional women, Su Lizhen in the film <In the Mood for Love> is also conservative about marriage. However, she is also longing for freedom, equality and love. The 23 sets of her cheongsam reflex the changes of her feelings. While in <2046>, Su Lizhen is a mysterious gambler who wears a black cheongsam. Instead of wearing the gorgeous and sexy cheongsam, Bai Ling wears the restrained and simple one, reflecting herself as a loser in love. In <The Grandmaster>, as an independent woman, Gong Er wears a loose dark cheongsam, while the traditional housewife Zhang Yongcheng wears the cheongsam of warm colors. Wong Kar-wai explores the sensitive and complex psychology of women. The female characters in his movie all change between the active and passive images according to their feelings and psychology. They are modern women who desire love. Hong Kong and the post-modern spirits are influenced by both eastern and western culture, which can be demonstrated by Wong Kar-wai’s films. The women in Wong Kar-wai’s films are not traditional eastern women. Instead, they are subversive and independent, showing the challenging feminism. The women portrayed in Wong’s films not only convey the traditional oriental aesthetic form, but also conform to the fashion, which integrate the postmodernism and express the feminism under the gender balance. 왕가위는 홍콩영화 감독 중에서 개인 스타일이 특히 강하며 아시아 문예 영화를 대표적으로 이끄는 감독이다. 그의 영화 작품은 독특한 미학적 분위기와 기능적 가치를 내포하고 있기에 왕가위 영화에 대한 연구는 영상 이론, 문화적 측면에서 가치를 지닌다. 왕가위는 40여 년간 총 12편의 영화를 감독하였다. 그는 작품마다 다양한 유형의 여성 캐릭터를 보여준다. 본 논문은 왕가위의 영화 작품 중 <화양연화>, <2046>, <일대종사>를 연구 대상으로 하여 영화 속 여성 캐릭터들이 입고 나오는 치파오를 중심으로 여성성을 분석하는 것을 목적으로 한다. 이를 위해 문헌 연구와 사례 분석을 진행하였다. 연구결과는 다음과 같다. <화양연화>의 소려진은 전통적인 여성의 보수적인 결혼관을 갖고 있을 뿐만 아니라 자유, 평등, 사랑에 대한 동경도 갖고 있다. 영화 속 23벌의 치파오 변신을 통해 내면의 감정 변화를 은유했다. <2046>의 소려진은 검은색 치파오를 입어 신비로운 여자 도박꾼을 표현했고, 백령은 화려하고 섹시한 치파오에서 절제되고 심플한 치파오를 바꿔 입음으로써 사랑에 실패한 심리 상태를 표현했다. <일대종사>에서 궁이는 헐렁한 짙은 색 치파오를 입어 독립적인 여성 캐릭터를 표현했다면, 장영성은 따뜻한 색 계열의 치파오를 입어 전통적인 가정주부 이미지를 표현했다. 왕가위는 여성의 민감하고 복잡한 심리를 탐색하였는데, 등장하는 여성 캐릭터는 그 감정과 심리에 따라 적극적인 여성과 수동적인 여성 사이에 존재하는 캐릭터를 갖고 있으며 이들은 사랑에 적극적으로 목마른 현대 여성이다. 동·서양 문화의 영향을 많이 받은 홍콩의 특수한 배경과 포스트모더니즘의 시대 정신은 왕가위의 창작에 반영되었고, 그에 따라 왕가위가 형상화한 여성성은 전통예속에 매여있는 동방의 여성상과 더불어, 전복적이고 도전적인 여성주의의 주체의식을 가진 여성의 모습을 나타냈다. 왕가위 영화에서 창조된 여성 형상은 전통적인 동방의 심미형태를 전달함과 동시에 시대의 흐름을 따라 포스트모더니즘을 융합시켰고, 성별 균형 하의 여성주의 사상을 나타냈다.

Fluosilicic acid(H2SiF6) is recovered as aqueous solution which absorbs SiF4 produced from the manufacturing of industrial-graded H3PO4 or HF. Generally, fluosilicate salts prepared by the reaction between H2SiF6 and metal salts. Addition of fluosilicate salts to cement endows odd properties through unique chemical reaction with the fresh and hardened cement. In this study, two-component fluosilicate salt based chemical admixtures(MZ) of 4%, 6% and 8% concentration were prepared by the reaction of H2SiF6(25±2%) and metal oxides(ZnO, MgO). The effect of concentration of MZ at a constant adding ratio on the hydration and watertightness of cement were investigated respectively. In a cement containing MZ, metal fluorides such as CaF2 and soluble silica by hydrolysis were newly formed during hydration. The total porosity of the hardened cement was lower in the presence of MZ because of packing role of metal fluoride and pozzolanic action of soluble SiO2. Consequently, the watertightness of the hardened paste containing MZ was more improved than non-added(plain) due to an odd hydration between cement and MZ. This study was performed to know watertightness and reduction effect and crack occurred by hydration heat, restraint of multiplication of hydration heat, through mechanical test, strength test and crack control test using fluosilicate salt based inorganic compound made from by-product during phosphoric acid manufacturing process. Mix proportions for experiment were modulated at 0.45 of water to cement ratio and 0.5-2.0% of adding ratio of fluosilicate salt based inorganic compound. Evaluation for watertightness of concrete was carried out permeability, absorption test and porosity analysis. Effect of crack reduction was evaluated by length, drying shrinkage as well as stress change of hardened concrete at unrestraint/restraint state and also elucidated crack pattern on the concrete surface. It is ascertained that characteristics of crack resistance and watertightness for concrete was improved by an adequate addition of fluosilicate salt based inorganic compound.
