  • In this study, the effect of particle size on the combustion characteristics of pulverized sub-bituminous coal was experimentally investigated. A laminar-flow-entrained reactor was designed and implemented to realize the desired heating ratio and temperature corresponding to the combustion atmosphere of a pulverized-coal-fueled furnace. The flame length and structure of burning particles according to different sizes were investigated. Coal combustion processes were clearly distinguished by direct visual observation of the flame structure. The onset point of volatile ignition is greatly affected by changes in the particle size, and the burning time of the volatiles is least affected by changes in the particle size. The length and instability of char flame also increase with the increase of the particle size. However, the char consumption rate within the residential time remains nearly constant.

  • Abstract Monitoring is the most critical element in implementing "forest carbon offset project" to enhance the visibility of CSR (Corporate Social Responsibility) in North Korea. This study is intended to explore monitoring potential in terms of forest carbon offset project using satellite image for Baekdu mountain of North Korea. The permanent record of standard satellite remote sensing system demonstrated its capability of presenting area-wide visual evidences of monitoring conditions in Mt. Baekdu mountain of North Korea (site suitability, carbon stock by forest biomass growth, carbon emission by forest biomass loss, deforestation and degradation, environmental, social and economic impact specified in the Carbon Sequestration Law). It doesn't seem very difficult to comply with monitoring requirements for "the forest carbon offset project" due to the probative value of satellite data. Therefore, it could be considerable or realistic approach to utilize CSR based forest carbon offset project as a point of reform and open-door in North Korea. It is anticipated that this research output could be used as a valuable reference for Korea-based enterprises to ensure monitoring potentials using satellite image in exploring forest carbon offset project sites in North Korea.

  • In this paper, we propose the chromatic adaptation models (CAM) for the variations of the luminance levels. A chromatic adaptation model, CAM$\Delta$Y , is proposed according to the change of luminance level under the same illuminants. The proposed model is obtained by the transform the test colors of the high luminance into the corresponding colors of the low luminance. In the proposed model, the optimal coefficients are obtained from the corresponding colors data of the Breneman's experiments. In the experimental results, we confined that the chromaticity errors, $\Delta$u'v', between the predicted colors by the proposed model and the corresponding colors of the Breneman's experiments are 0.004 in u'v' chromaticity coordinates. The prediction performance of the proposed model is excellent because this error is the threshold value that two adjacent color patches can be distinguished. Additionally, we also propose equal-whiteness CCT curves (EWCs) by CAM$\Delta$Y according to the luminance levels of the surround viewing conditions. And the proposed EWCs can be used as the theoretical standard which determines the reference white of the color display devices.

  • Various difficulties and inconveniences arise from having a mentally handicapped child in a family and these place many demands on mothers. There are few studies in Korea on these demands nor on what mothers go through with their mentally handicapped daughters' menarche and puberty. The purpose of the study was to examine the experiences of mothers of mentally handicapped daughters, as it relates to their daughters' menarche and the beginning of puberty. With indepth interviews, both in person and by telephone and participant observation the study used a qualitative research methodology to attempt to understand the experiences of these mothers. The data were gathered from October 1995 to April 1996. The subjects for the research included nine mothers of mentally handicapped daughters whose ages ranged from 12 to 18 and who attended one of three special schools located in either Inchon or Seoul. The data were recorded and analyzed : meaningful statements were grouped according to subjects raised by the mothers. Content Analysis was also applied to identify similar content and confirm common experiences. and to highlight concepts and categorized them. The results of this study are as follows. Five categories were identified : mothers' emotional responses to their mentally handicapped daughters' menarche and menstration were of severe despair accompanied by anxiety, guilt, fear, anguish, shame and pity because the mothers were afraid their daughters would not be able to use appropriate hygienic measures during menstration and the mothers felt heavily burdened in having to look them. The mothers also had negative feelings about their daughters' physical development. The experience of mothers related to their daughters' possibilities for marriage and pregnancy were of powerlessness, distress, withdrawal, fear. pity and desperation and they were afraid that their daughters might be violated sexually. The mothers rejected the possibility of marriage and pregnancy for their daughters and instead planned very restricting futures for them. The mothers used various coping methods to bring meaning to their lives. Because the negative emotional responses of the mothers. nurses need to work to empower mothers to overcome these negative responses. Sex education can also play an important role especially for the daughters especially through the use of visual aids. Further, nurses should understand the tearing difficulties of mentally handicapped daughters, what mothers need and also what they experience with their mentally handicapped daughters. In conclusion, nurses should understand the negative experiences of the mothers in relation to their mentally handicapped daughters' menarche, help the mothers cope with the negative. emotions through real life education and counselling. In addition, there is a need for nursing interventions and an administrative system which will minimize the prejudices of society towards handicapped people.

  • Display quality assessment has been a long standing issue due to the diversity of display devices and the rapid growth of display technology. The conventional display quality assessment methods are mostly those methods which evaluate qualities of a display by measuring physical quantities, but the results from the methods are not equal to the perceived results which are acquired with subjective experiments. Thus, we need to solve the above contrariety as well as establish the quantitative correlation between physical and perceived results. This paper proposes the systematic method of evaluating relative perceived qualities among various display devices and quantifies these relative perceived qualities. The proposed method is based on Analytic Network Process(ANP), which is one of the most popular decision making methods in the business administration field. We also adopted three evaluation criteria, which consist of color, shape and depth, in order to reflect the human visual system and chose eight sub-criteria related to display characteristics via question investigation. We carried out a subjective experiment and the proposed method which evaluated perceived qualities of two display devices(TFT-LCD, OLED) in order to prove the similarity between their results. As a result, it is proved that the order relationship between perceived qualities was the same as the order of results got through the subjective experiment.

  • As the field of film aesthetics expands, the concept of classical the mise-en-scene expands too its scope. This paper examines the concept of mise-en-scene through spatial connections. The primary goals of this study are understanding the relation between the frame and the shot, the continuity between the scene and the sequence, and the aesthetic dimension to the plan-sequence. In modern cinema theory, the elements of mise-en-scene are more emphasized in terms of efficiency, but this study is concerned that the classical aesthetic system is still important. To this end, we examine the concept of plan-sequence, which was called the best technique of past visual realism aesthetics, is utilized in digital cinema. Finding significance for the modern use of plan-sequences is a secondary goal of this paper and we expect it to be a stepping stone to search for the aesthetics of digital cinema. The plan-sequence is one of the important factors that can be evaluated in the preparation and application of the event for the movie director. In the real world where the film itself is used commercially, digital film will have a conceptual tool that can utilize allegorics of 'geopolitical unconsciousness' through plan-sequences.
