This paper presents a new method for load distribution in a single-level tree network equipped with front-end processors. This method focuses on effective data distribution over a number of processors minimize job processing time. Optimal multiple installment load distribution algorithm is presented. Minimum number of processors that maximizes efficiency is decided theoretically.

본 연구의 목적은 하이데거의 존재론에 대한 돌봄윤리를 토대로 ‘가족’ 주제의 그림책 읽기를 통해 삶의 주체로서 등장인물이 어떻게 표현되는지와 존재론적 돌봄윤리가 어떻게 나타나는지를 살펴보는 것이다. 분석대상 ‘가족’ 그림책은 유지연의 『엄마의 초상화』, 최혜진의 『아빠와 토요일』, 고은결 글, 이명환 그림의 『사랑하는 당신』이다. 연구 결과로 첫째, 삶의 주체로서 등장인물은 기투하며 적극적으로 살아가는 존재, 자연과 교감하는 존재, 사랑으로 돌봄을 실천하는 존재로 해석되었다. 둘째, 존재론적 돌봄윤리는 ‘존재 의미에 대한 물음으로서 돌봄’, ‘존재 진리의 터에 대한 물음으로서 돌봄’이 나타났다. 이러한 연구결과는 돌봄의 주체가 되는 부모와 유아교사에게 돌봄윤리에 대한 근원적 성찰과 인간존재에 대한 이해의 폭을 확장하여 돌봄 실천의 방향성을 제시한다는 점에서 의의가 있다. The purpose of this study is to read in Heidegger’s existence and care ethics how the characters in the ‘family’ themed picture books are represented as the existential subjects and how the care ethics can be applied to interpret the stories. The ‘Family’ themed picture books analyzed are Yoo Ji-yeon's 『Portrait of Mom』, Choi Hye-jin's 『Saturday with Daddy』, Ko Eun-gyeol's writing and Lee Myung-hwan's illustrated 『My sweet love』. As the result of the research, first, as the subject of life, the characteres were represented as the subjects who actively lived, interacted with nature, and practiced caring with love. Second, we can find existential care ethics as a question of the meaning of existence and as a question of the site of existence truth. These findings are meaningful in that they present the direction of care practice to parents and early childhood teachers who are the main agents of care, and that they can expand their reflection on care ethics and their understanding of human beings.

The important properties of a tissue are softness, strength, and absorbency for performance. The softness is one of important properties, and an objective evaluation method is required for purchase decision because subjective feeling is not enough. Surface smoothness can be measured by a stylus profiling, an electron microscope, or an optical method. Even objective measurement methods may have different results depending on types of measurement methods. The softness of the toilet tissue and the facial tissue of two companies was measured after using the internal and external softener. The softness was measured by using the KES-SE-SR surface tester as a probe method and the fractal dimension theory was applied. The correlation between the softness results and two methods such as the tissue softness analyzer and image analysis were compared. Results of the tissue softness analyzer and image analysis showed that softness increased when using internal and external softeners, but FD values increased. When using internal and external softener, it was assumed that hydrogen bondings of fibers at tissue surface were disrupted and the fractal dimension value increased.

Cellulose is one of the constituents of plants and is an environmentally friendly resource with a semi-permanent supply and high biodegradability. CNF from cellulose is useful for various purposes. CNF has high aspect ratio and high specific surface area and it is excellent in mechanical properties and thermal stability, and it has shear-thinning flow characteristics. When CNF is coated on paper, it provides high barrier property with excellent network forming ability. The surface roughness of the coated paper is one of the characteristics that determine the quality of coated paper and printing. The surface roughness is measured by the stylus profiling, the air leak, and the optical image analysis methods. Each analysis method has certain characteristics, so surface roughness of coated paper was analyzed by those three methods and results were compared. After mixed coating of CNF and oxidized starch, the degree of roughness was increased in the probe method and the air leakage method when the coating weight and the amount of CNF were increased. The degree of roughness which is measured by Optitopo decreased when the mixed solution was coated. Because the range of roughness measured by each measurement method is different, it might give different tendencies.

Increased Non-permeable areas which have resulted from civilization reduce the volume of groundwater infiltration that is one of the important factors causing water shortage during a dry season. Thus, seeking the efficient method to analyze the volume of groundwater in accurate should be needed to solve water shortage problems. In this study, two different watersheds were selected and precipitation, soil group, and land use were surveyed in a particular year in order to figure out the accuracy of estimated infiltration recharge ratio compared to Web-based Hydrograph Analysis Tool (WHAT), The volume of groundwater was estimated considering Antecedent soil Moisture Condition (AMC) and Curve Number (CN) using Long Term Hydrologic Impact Assessment (L-TH1A) model. The results of this study showed that in the case of Kyoung-an watershed, the volume of both infiltration and baseflow seperated from WHAT was 46.99% in 2006 and 33.68% in 2007 each and in Do-am watershed the volume of both infiltration and baseflow was 33.48% in 2004 and 23.65% in 2005 respectively. L-TFIIA requires only simple data (i.e., land uses, soils, and precipitation) to simulate the accurate volume of groundwater. Therefore, with convenient way of L-TKIA, researchers can manage watershed more effectively than doing it with other models. L-THIA has limitations that it neglects the contributions of snowfall to precipitation. So, to estimate more accurate assessment of the long term hydrological impacts including groundwater with L-THIA, further researches about snowfall data in winter should be considered.
