현재까지 수리학 분야에서 가장 많이 회자되고 인용된 공식이 있다면 아마도 1890년에 발표한 Manning의 유속 공식이라고 해도 과언은 아닐 것이다. 그만큼 그 쓰임새가 많았을 뿐만 아니라 사용의 편리성과 정확도에서도 매우 우수하였기 때문일 것이다. 그러나, 아무리 우수한 공식이라도 약점이 있듯이, Manning의 유속공식 역시 조도계수n을 추정하는데 많은 어려움이 있는 것도 주지의 사실이다. 이러한 어려움을 극복하기 위하여, 본 연구에서는 확률통계에서 사용되는 엔트로피 개념을 이용한 3차원 유속분포식인 Chiu의 유속공식을 사용하였다. 그러나 지금까지 실증적으로 Chiu의 유속공식과 Manning의 유속공식을 비교분석하였던 논문은 Chiu와 Choo의 논문에서 일부 언급된 것 외 논문에서는 찾아볼 수 없는 것이 현실이다. 따라서 본 연구에서는 하상경사를 임의로 변경 가능한 실험수로를 선택하여 정밀법에 의한 유속측정을 우선 실시하였다. 같은 지점의 같은 단면에서 하상경사(Ө)가 0.000935부터 0.025794까지 28번의 경사변화를 주고 각 경사마다 유량을 측정하여 28개의 유량측정 데이터를, Chiu의 유속공식과 Manning의 유속공식에 각각 적용하여, Chiu의 M과 Manning의 n사이의 관계뿐만 아니라, 하상경사변화에 따른 관련인자들을 함께 분석하였으며, 실측된 평균유속과도 함께 분석하였다.

Objectives: The aim was to confirm the stem cell-like properties of the dental pulp stromal cells and to evaluate the morphologic changes during in vitro chondrogenesis. Materials and Methods: Stromal cells were outgrown from the dental pulp tissue of the premolars. Surface markers were investigated and cell proliferation rate was compared to other mesenchymal stem cells. Multipotency of the pulp cells was confirmed by inducing osteogenesis, adipogenesis and chondrogenesis. The morphologic changes in the chondrogenic pellet during the 21 day of induction were evaluated under light microscope and transmission electron microscope. TUNEL assay was used to evaluate apoptosis within the chondrogenic pellets. Results: Pulp cells were CD90, 105 positive and CD31, 34 negative. They showed similar proliferation rate to other stem cells. Pulp cells differentiated to osteogenic, adipogenic and chondrogenic tissues. During chondrogenesis, 3-dimensional pellet was created with multi-layers, hypertrophic chondrocyte-like cells and cartilage-like extracellular matrix. However, cell morphology became irregular and apoptotic cells were increased after 7 day of chondrogenic induction. Conclusions: Pulp cells indicated mesenchymal stem cell-like characteristics. During the in vitro chondrogenesis, cellular activity was superior during the earlier phase (within 7 day) of differentiation.

This studies were carried out to evaluate the textural characteristics of traditional fermented vegetable food of Korea namely "KIMCHI". "KIMCHI" samples were prepared by adding 2,3,4, and 5% of NaCl to Chinese cabbage leaves. Morever, half of each sample batches were mixed with 0.1% weight of "Saewoojeot" namely pickled shrimp paste as an additive. "KIMCHI" was fermented at 25℃ during experiment. pH value and texture of samples were investigated at 1hr, 24hrs and 96 hrs of fermentation to compare with fresh cabbage. Influences of NaCl concentration, legion of cabbage, length of cabbage leaves and addition of pickled shrimp paste were studied. Results were as follows: Hardness and Brittleness values were larger with outer cabbage leaves than inner one, longer leaves were larger than that of shorter with outer cabbage leaves of Hardness, Cohesiveness, Elasticity, Adhesiveness, Brittleness and Chewiness were decreased as NaCl concentration increases, especially when pickled shrimp paste was added.

This study has performed to investigate and evaluate the amount of pollutants and the status of water quality of the Hyung-San River and prediction water pollution loads. In the field survey('94.11-'95.3), mean concentrations of BOD were found 0.78-4.90ppm, respectively, which were exceeding the second grade at inflow point of Sindang stream The predicted BOD pollution loads of Hyung-San river in 1996, 2001, 2006, 2011 were 13,068.3 kg/day, 13,003.1 kg/day, 9,355.6 kg/day, 9,506.6 kg/day.

Piaget의 認知 發達 理論

1. In order to approach to the understanding of the cognitive theory of Jean Piaget, I described the theory into 4 parts, that is: I described his life and work in part Ⅰ, the basic characteristic oh his theory in part Ⅱ, the concept of development and developmental stages in part Ⅲ, and then set forth the summary and criticism about his theory. 2. Piaget dedicated all of his creative energies to uncovering the nature and direction of intellectual development. He can best be described as a scientist researching the nature and logic of human development. 3. It is advisable to examine the basic assumptions of Piaget's developmental theory, and which can be summarized under the following sub-headings: ①Approach to theory formation, ② The order of the cosmos, ③ Etiology of human behavior, ④ Fundamental human values, ⑤ Core of human behavior, ⑥ The newborn, ⑦ The physical, social, and ideational environment. 4. Piaget's concept of development can be summarized by the six following generalizations: ① There is an absolute continuity of all developmental processes. ② Development proceeds through a continuous process of generalizations and differentiation. ③ this continuity is achieved by a continuous unfolding. Each level of development finds its roots in a previous phase and continues into the following one. ④ Each phase entail a repetition of processes of the previous level in a different from of organization(schema). Previous behavior patterns are sensed as inferior and become part of the new superior level. ⑤ The differences in organizational pattern create a hierarchy of experience and actions. ⑥ Individuals achieve different levels within the hierarchy, although there is in the brain of each individual the possibility for all these developments but day are not all realized. 5. Piaget's writings introduce a variety of developmental divisions. For instance, in Piaget's works of 1956, he illustrates a developmental continuum by a division into three major phases: ① The sensorimotor phase (roughly, ages:0-2) ② the period of preparation for conceptual thought (roughly, ages:2-11/12) ③ The phase of cognitive thought (roughly, ages: 11 or 12 and up) 6. Piaget's theory furnishes us with a frame of reference. His developmental trends describe individual potentiality. The actual developmental profile of each individual resembles a barogram showing peaks in some areas and depressions in orders. In addition, variations may exist at any one point in an individual's approach to everyday problems. Basically, however, his theory pointedly demonstrates that there are regular patterns in cognitive development which are experienced by everyone. In turn, such understanding allows. us to predict for an individual his mode and range of comprehension all along on the course f his development.

所得再分配에 관한 硏究 : 公共勤勞福祉 增大方案을 중심으로 WITH EMPHASIS ON THE WELFARE POLICY FOR WORKING FAMILIES

정주성 단국대학교 대학원 1992 學術論叢 Vol.16 No.-

The purpose of this paper is to consider a properiety of the welfare policy for the working families as a positive redistribution policy in Korea. A redistribution function in capitalistic economy is the major part of government function because of the capitalistic economy has not an ability to correct the inequality automatically. Recently an income redistribution policy is emphasized by the working families in Korea. The reason is that the wages of the working families was raised in the last several years but they feel that they are low their real income and econnomic status rather than before on account of a speculation in real estate. So they demand intensively not only a raise in wages but an increase of welfare benefits for the real income rise. From this viewpoint, we can estimate that an expanison policy of working families welfare like 'the working families housing policy' is effective. Now an improvement of income distribution is not a bottleneck of growth but a precondition for growth in korea economy. It is important that we realize that the stabilization of prices and the eradication of speculation in real estate is the efficient redistribution policy.
