  • 방향성 그라디언트 매스크의 크기값을 네 방향 에지 정보에 적용하여 선택된 두 방향의 가중된 합으로 표현하는 새로운 에지기반보간 기법 (Directional edge based interpolation, DEBI)을 제안한다. 네 방향의 그라디언트 정보를 추출하기 위한 등방성 그라디언트 매스크를 소개하고, 영상 보간을 이웃한 후보 영역 중에서 가장 유사한 영역을 선정하며, 선택된 영역만을 이용하여 보간을 실시한다. 보간 방향은 등방성 그라디언트 매스크의 최소 절대값을 나타내는 두 방향만이 이용되고, 그라디언트 매스크의 에지성분 특성에 따라서 영상 보간 방향이 결정된다. 두 방향의 보간값은 그라디언트 값을 가중치로 이용하는 방법으로 주변 간을 단순 평균에 의한 기존의 방법에 비하여, 영상 밝기 변화가 심한 곳과 경계선 영역에서 효과적임을 실험으로 증명하였다.

  • In this paper an attempt is tried to answer the following questions : What does ergonomics have to do with work satisfaction\ulcorner Is there more satisfaction when ergonomics have applied in the design of work\ulcorner Is ergonomics important for work satisfaction\ulcorner This paper is started by defining the concept of satisfaction and ergonomics which is still at a comparatively early stage of development, and the effect of this in practice is that the majority of ergonomics assignments involve research. And then there discussions difficult theories of motivation and satisfaction such as Maslow' theory and Horzberg's theory. And in this paper I'll try to formulate the logical consequences of those theories for the relation between ergonomics and satisfaction. Finally I'll conclude with some ideas about the significance of ergonomics satisfaction. The level of satisfaction experienced with one's work is a complete function of the degree to which different values connected with work and with its concomitant results are attained, the opportunities perceived for the attainment of these values, the relative advantages and disadvantages of the work situation compared with that of other people, and personality and cultural determinants. As for ergonomics, the ergonomist's comprehension will need in future to encompass more of the emotional, attitudinal and motivational facts of working people. Ergonomically - designed work will not produce high degrees of satisfaction, but absence of ergonomics in design will be connected with some dissatisfaction. So this paper suggest s that ergonomics has some significance for work satisfaction and that social Psychological efforts to enhance work satisfaction cannot easily succeed without taking into account human-factors principles.

  • 도로의 경우, 서비스 수준은 A에서 F까지로 구분되어 있다. (도로용량 편람, 건교부). 장래 도로시설 계획 시, 시간당 교통량과 용량을 기준으로 하여 고속도로의 경우 서비스 수준 C를, 국도의 경우 D를 목표로 삼고 있는 실정이다. LOS C의 경우 용량의 약 75%수준에 해당되는 수준이다. 하지만, 철도의 경우는 현재까지 서비스 수준에 대한 개념이 정리되어 있지 못하고 있을 뿐만 아니라, 철도시설 계획 시에는 하루수요를 사용하고 있으며, 구체적인 서비스 수준을 고려하고 있지 못한 실정이다. 철도의 계획 시 용량과 서비스 수준은 결국 운영자와 승객의 입장에서 어느 정도의 철도서비스를 제공할 것인지에 대한 공감대를 형성하는 매우 중요한 사항임에도 불구하고, 명시적으로 서비스 수준을 고려하지 못하고 있는 현실이다. 또한 사용자의 수요의 발현도 결국은 철도서비스의 질에 달려 있는 점을 고려하면 철도서비스 수준을 명시적으로 고려하는 게 기대할 수 있는 수요를 정확하게 계산할 수 있도록 해 줄 것이다.

  • Theory of the building heat transfer is generally limited to the heat flux to the surfaces of windows and walls, which influences the indoor climate of a building, in the field of architectural environmental engineering. While the heat flux from the buildings to their environment has been considered in the viewpoint of urban climate, its conventional theory have been rarely examined. The purpose of this study is to propose a building-urban heat transfer model for defining the relation between the building and the urban climate by extending the building heat transfer model. In this study, the extended building heat transfer model, where response factor method is used, is established on the urban space and the indoor space by the boundary of building envelopes. Computer simulation (HASP/ACLD) is conducted on the subjected urban area by the established building-urban heat transfer model. As a result it is logically proved that the short waves of solar radiation, which interact with long Waves of radiation from the buildings and the earth, increase the urban air temperature ana buildings largely influence on the urban climate.

  • Let X be a Tychonoff space and ${\sum}(X)$ the set of all the subrings of C(X) that contain $C^*(X)$. For any A(X) in ${\sum}(X)$ suppose $_{{\upsilon}A}X$ is the largest subspace of ${\beta}X$ containing X to which each function in A(X) can be extended continuously. Let us write A(X) ~ B(X) if and only if $_{{\upsilon}A}X=_{{\upsilon}B}X$, thereby defining an equivalence relation on ${\sum}(X)$. We have shown that an A(X) in ${\sum}(X)$ is isomorphic to C(Y ) for some space Y if and only if A(X) is the largest member of its equivalence class if and only if there exists a subspace T of ${\beta}X$ with the property that A(X)={$f{\in}C(X):f^*(p)$ is real for each $p$ in T}, $f^*$ being the unique continuous extension of $f$ in C(X) from ${\beta}X$ to $\mathbb{R}^*$, the one point compactification of $\mathbb{R}$. As a consequence it follows that if X is a realcompact space in which every $C^*$-embedded subset is closed, then C(X) is never isomorphic to any A(X) in ${\sum}(X)$ without being equal to it.

  • In modern society, the place we live and reside decides quality of our lives and pattern of behaviors, and it appears with indeterminative and circulating forms. The place provides different experiences and restrictions to us as intentions of human being and order of nature merges into each other. Formation of such place decides the character depending on its relationship of orders. There would be various methods to prescribe for the ability, that is, characteristics, of space. It is the purpose of this research to classify different components defining the character of the space based on a general notion of place and to find out how it is reflected in the space itself. It is to analyze difference case studies by finding out the relationship between the factors affecting the formation of places and aspects of different expressions within the space. The research would assist in forming different harmonious places reflecting the phases of this modern time as designing interior spaces, and it is also to provide footstone for the formation of space which is not only growing but also future oriented.

  • This study was carried out to investigate the relation between seepage losses and flow section area in earth canals. Totally 77 seepage measurement was gained by ponded method and the tested canals belong to the irrigation area of Farmland Improvement Association in each province, Korea. The results obtained from this study may be used as a reasonable criteria for the estimation of canal seepage losses in the design of irrigation systems. Obtained results are summarized as follows: 1. Average seepage rates in each Soils is 14cm/day in ML, 6. 3cm/day in CL and 24.9 cm/day in SM. 2. Water depth and water surface width in eath canals have little influenced on the seepage rate, while the seepage losses was increased in proportion as the water surface width lengthens. 3. A formula of S=C.An defining a relationship between seepage losses and flow section was derieved as follows. ML:S=O. 35 VA 1.20 (m$^3$/day/m) CL:S=O. 13 VA 0.84 SM:s=O.67VA-1.56 4. The average seepage loss rates per 1km of canal are as followings. Measured Time ML CL SM 0-4 hrs 2.2% 0.6% 4.5% 4-2 4hrs 1.0% 0.15% 2.0% In above table we may obtain the following results. The first row is suitable for the canal having short delivery time of irrigation, while the second row for the canal having long delivery time.

  • Personality factors and ethical values are considered as vital element in social and professional life. This present research aims to explore the relationship between Personality and Job Satisfaction. Further, we tried to test the moderating effect of Islamic work ethics (IWE) in the relationship of Personality traits with Job satisfaction. Convenience sampling was used in defining sample as in Pakistan there is no data base which provides information regarding number of employees. Due to moderating variable the data has been collected from respondents who identify themselves as Muslim. To collect data from respondents Self-administered, close-ended questionnaires and e-questionnaire were used in this study and respondents were targeted in the normal working environment. Correlation and regression analysis was used to analyze the data statistically. The results of study indicated that neuroticism exhibits significant negative effect on job s atisfaction. Also, openness to experience, agreeableness and conscientiousness showed positive effect on job satisfaction. Whereas, extraversion exhibits no effect on job satisfaction and IWE has a negative effect on job satisfaction. However, the output indicates that IWE do not act as moderator in the relation of agreeableness and conscientiousness with job satisfaction moderation effect of IWE is observed between the relationship of neuroticism, extraversion and openness to experience with job satisfaction.

  • CAD systems used in various manufacturing industries have been rapidly switched from 2D to 3D. 3D-based design is becoming common in the shipbuilding industries too. However, there is still a demand for 2D drawings for ship production. So, it is necessary to continually improve 2D drawings. One way to improve 2D drawings is to add production information to the drawings. To do this, it is necessary to define the relation between the geometry information and the production information. Various types of drawings, which is inevitable because each drawing has its own purpose, make it difficult to define relations. This process can be simplified if the drawing information is neutralized. XML is a standard format for defining neutral data, and is already being used in various fields. In this study, a neutral augmented drawing has been defined by neutralizing the drawing information based on XML, and implemented for the allocation of their information with high quality of readability as well.
