영상 이미지 감성으로 행복 또는 불행, 긴장 또는 평온의 구분 감성을 트리형식으로 가중치를 부여하여 평가한다. 영상 이미지 대표평가 감성인 명도대비를 평가 기준으로 1차는 행복, 불행 또는 긴장, 평온이고 2차는 종속성을 지닌 세분화된 영상 이미지 감성으로 구분한다. 4개의 감성인식을 수치화 된 명도대비 데이터로 측정한다. 평가 구현은 OpenCV를 통해 명도대비를 그래프화하여 긴장, 평온, 행복, 불행 값의 변화에 따라 4개 감성으로 구분하여 컴퓨팅한다. 감성 컴퓨팅은 명도대비의 입력 값에 따라 '불행'을 '행복'으로 또는 '긴장'을 '평온'으로 감성적인 변화를 구현한다. 감성 컴퓨팅은 영상 감성의 규칙성을 계산화 된 컴퓨팅 시스템으로 제어할 수 있고 명도대비 값에 따라 감성의 변화를 구현한다. 향후 산업방향에 감성 인식의 적용에 대한 긍정적인 역할을 할 것이다.

이미지를 감성으로 쾌 또는 불쾌, 긴장 또는 평온의 구분 감성을 트리 형식으로 가중치를 부여하여 평가한다. 이미지 대표평가 감성인 명도대비를 평가 기준으로 1차는 쾌, 불쾌 또는 긴장 또는 평온이고 2차는 세분화 이미지 감성으로 구분한다. 4개의 감성인식을 수치화 된 명도대비 데이터로 측정한다. 평가 구현은 OpenCV를 통해 명도대비를 그래프화하여 긴장, 평온, 쾌, 불쾌 값 변화에 따라 4개 감성으로 구분하여 컴퓨팅한다. 감성 컴퓨팅으로 명도대비의 입력된 값에 따라 '불쾌'를 '쾌' 또는 '긴장'을 '평온'으로 감성적 변화를 줄 수 있다. 이미지 감성의 규칙성을 계산화 된 컴퓨팅 시스템으로 제어할 수 있고 향후 산업방향에 감성 인식의 적용에 대한 긍정적인 역할을 할 것이다.

$TiO_2$ films were deposited on a glass substrate with RF magnetron sputtering and then surface of $TiO_2$ films were electron beam irradiated in a vacuum condition to investigate the effect of electron bombardment on the thin film crystallization, surface roughness and gas sensitivity for hydrogen. $TiO_2$ films that electron beam irradiated at 450eV were amorphous phase, while the films irradiated at 900 eV show the anatase (101) diffraction peak in XRD pattern. AFM measurements show that the roughness is depend on the electron irradiation energy. As increase the hydrogen gas concentration and operation temperature, the gas sensitivity of $TiO_2$ and $TiO_2$/ZnO films is increased proportionally and $TiO_2$ films that electron beam irradiated at 900 eV show the higher sensitivity than the films were irradiated at 450eV. From the XRD pattern and AFM observation, it is supposed that the crystallization and rough surface promote the hydrogen gas sensitivity of $TiO_2$ films.

There has been an increasing preference for product with cultural value as people have a growing cultural sensitivity and greater demand for cultural value in current global market. In response to that, countries need to develop cultural products which represent their distinctive cultures and traditions, and such efforts may aim to promote the creation of economically high value-added and enhance the cultural image. In this paper, first, we analyze the correlation between Culture, cultural industry and Cultural goods. In this context, my efforts centered initially on a thorough analysis on the current situation and environmental problems that Korean culture faces presently, and then, processed and organized them into major industry categories of character industry, through a statistical methodology, to estimate its market volume by industry and to analyze the inter-relationship and macro-economic pervasive effects among related industries as well as cultural window effects. This paper could lead to final practical solution and suggestions for optimum policy measures to be taken for a supreme cultural industry for Korea.

정보 검색에서 대부분의 질의 재구성 알고리즘들은 초기 입력 문서나 피드백 문을 이용 하여 질의를 재구성하므로, 질의 재구성 알고리즘의 검색 성능은 입력되는 문서들의 질 에 따라 달라진다. 본 연구에서는 질의 재구성 알고리즘의 입력 문서에 대한 성능 감도를 새로운 검색성능 평가방법을 개발하여 분석하였다. 또한 CIRA라고 불리는 새로운 평가기준을 개발하여 질의 재구성 사이의 성능 변화추이를 분석하였다. 세가지의 질의 재구성 알고리즘(질의나무 (query tree), DNF 방법, Dillon 방법)의 감도와 성능변화를 테시트 세트인 CACM, CISI, Medlars 상에서 분석하였다. 세 실험에서 질의나무가 가장 작은 CIRA를 취득했으며, 감도 분석에서는 비록 다른 알고리즘과 차이는 적으나 가장 높은감도를 나타냈다.

By the recently, Environmental pollution is serious by the highly economic growth and expansion of lively country basic industry. Especially, in case of industrial waste and life waste leaped into a pollution source. Also, research for processing of waste and recycling countermeasure is a pressing question on national dimension because it is prohibited an ocean disposal and reclamation. In this study, it looked for fracture characteristic value of recycling a coal ash to decrease environmental pollution by picky and exhaustion of natural resources and to reduce self-weight to prepare for a tall building and earthquake. So a coal ash examined to be possible to do as construction material. It achieved compressive strength test and three points bending test with initial notch depth rate and age for variables to show a basic research data. From the basis of the three points bending test, the fracture parameters - notch sensitivity, fracture energy, initial compliance were experimentally proposed. From the results of the compressive strength test, the elastic modulus was experimentally proposed. Also on the basis of the three points bending test, the fracture parameters - notch sensitivity, fracture energy, initial compliance were experimentally proposed. The results that the strength and fracture energy value are lower than concrete or mortar is described in this paper. Also, it shows that the deflection at fracture decreases as the age increases and the notch sensitivity decrease. However, it is judged to be available to construction material if research is continuously gone forward.

Performance and efficiency of hybrid (hydraulic-mechanical) pick-up device of deep sea manganese nodules collector are very sensitive to altitude and altitude of pick-up head relative to undulating seafloor. For this reason, motion control of pick-up head relative to the changing deep sea topography and other disturbances is of particular importance in design of pick-up device. The concept of design axiom is applied to a pick-up device of hybrid type. Kinematic analysis conducted in absolute Cartesian coordinates gives position, velocity, and acceleration of the hydraulic cylinders which enable the pick-up head to keep the preset optimal distance from seafloor. Inverse dynamic analysis provides the driving forces of hydraulic cylinders and the reaction forces at each joint. Design sensitivity analysis is performed in order to investigate the effects of possible design variables on the change of the maximum strokes of hydraulic cylinders. The direct differentiation method is used to obtain the design sensitivity coefficients.

In this study, hydrodynamic and mooring analysis for LNG FSRU moored by an internal turret with 9 mooring lines are numerically performed using commercial softwares, Hydrostar and Ariane. Met-ocean combinations for screening method are taken from wave governed condition(BV Rule Note NR 493) with relative heading between wave and wind between −45° and +45° and relative heading between wind and current between −30° and +30°. Extreme mooring analysis and sensitivity analysis are performed for intact and damaged (=one line missing) conditions and the parameters for sensitivity analysis are wave peak period, peak enhancement factor and line pretension. In the viewpoint of the design tension in mooring line, chain diameter is designed to satisfy safety factor for each conditions. As the chain diameter is increased from 152mm to 171mm, the designtension is reduced while the minimum breaking load is increased.

Color is infinitely more complex and challenging when the human element is factored in. The nature of fashion presents additional issues that must be addressed, allowing for even greater possibilities. Fashion trends and fashion colors could be used as a starting point for investigating many possible applications in fashion industry. Modern fashion industry received various information from many medias. Fashion trends and fashion colors must be referred to primarily when planning fashion goods among so much information. In this study, changes in fashion trends and fashion colors from 1966 to 1995 were investigated. The results indicated fashion trends and fashion colors were involved with community, culture and economy. Furthermore, important characteristics of fashion trends were summarized. In recent 30 years fashion trends and fashion colors appeared practical fashion and natural color, amenity fashion and mild color. According to the fashion changes in sensitivity, the color change was evaluated. Fashion colors displayed changes from sign effect to symbol effect. Especially black changed from minus image to plus image made it important fashion color.
