The propose of this thesis was to study the usage of the low-grade Vermiculite from the Chung Chong province and also to increase its Value-added. A series of experiments have been done for separation as well as heat-expansion characteristics of the Chung Chong Vermiculite some conclusions can be drawn as follows; 1. Vermiculite from Chung-Yang and Hong-Shung areas wear better than that from Palabora's mine in South Africa in terms of the usefulness for an organic fertilizer. 2. The ratio of the volume expansion of Vermiculite increased along with the temperature. 3. In general, the ratio of volume expansion of the vermiculite from Chung-Yang, Hong-Shung and Palabora's mine in South Africa increased with temperature. But it decreased temporarily in the vicinity of 850℃. The result seems to be due to temporary decrease in the latent heat as the crystal water in the crystals such as Ca_(10)(Mg,Fe)₂A1₄Si_(9)O₃₄(OH)₄, K(Fe,Mg)₃AlSi₃O_(10)(OH)₂and K (Fe,Mg)₃AlSi₃O_(10)(OH)₂evaporated. 4. Above 1050℃, the crystal structure began to change and resulted in partial destruction to produce some dusts. Finally sintering occurred.

The purpose of this study is to provide some basic data which can be helpful for improving the methods of mathematics teaching-learning emphasizing the affective factors by investigating the effect on affective characteristics and mathematical problem solving ability of the students on the elementary school sixth grade. In order to achieve these purpose, the following research problems were set up for the present study: The results of this study are as follows: First, it was appeared that there was not any difference on attitude on mathematics, belief, self-confidence and the degree of mathematical problem solving ability by sex. Second, it was appeared that there was some statistical meaningful difference on attitude on mathematics, belief, self-confidence and the degree of mathematical problem solving ability according to high middle low ability on mathematics which the students think that they have. Based on the results of this study, I'd like to give some suggestions as followings to provide some help to teaching and learning mathematics. First, the succeeding studies are needed by selecting different population from the population of this study, classifying low-ranking factors consisting of affective characteristics differently from this study, compounding each low-ranking factors in various manners like using new items, etc. Second, the succeeding studies are needed in this part, because what mathematical belief teachers have mathematics can have an effect on students' mathematical belief and action as well as on teachers' thinking process and action in the class. Third, the succeeding studies are needed to develop concrete field study and program which can be helpful for improving actually students' affective behavior characteristics in school field.

용융동및 Speiss와 Calcium Ferrite Slag사이에서 As의 분배평형에 관해서

강헌찬,황용길 동아대학교 공과대학 부설 한국자원개발연구소 1987 硏究報告 Vol.11 No.2

The distribution of arsenic between calcium ferrite slag and liquid copper was measured at 1473 K under controlled CO-CO₂ atmospheres. The distribution ratios defined by % X in slag/%X in metal, were plotted against the oxygen potential. The distribution ratios of arsenic between speiss and calcium ferrite slag were also investigated. From the above experiments, the results obtained are as follows : 1. The liquidus and solidus lines divide the equilibrium diagram into Fe-Cu-As system at 1150℃. 2. In general arsenic has a greater affinity fir Fe-As systems than for Cu-As systems. 3. The distribution ratios of arsenic between speiss or liquid copper and slag increase with the increased content of the CaO in calcium ferrite slag or oxygen potential.

Most automated cervical cancer screening systems are recognized through the feature extraction process by segmenting the cell image. There are problems such that an efficient segmentation of the cell image is difficult, and segmentation and feature extraction process takes long time. To solve these problems, PapNet system based on the artificial neural network was developed. However, it takes long time to recognize because huge amount of pixel-based features is inputted into neural network. In this paper, we propose a feature extraction technique which is based on the variable size block and makes use of the color information. The proposed technique can reduce running time by decreasing the input number of neural network by dividing the region of the cell around the center into blocks. This technique shows the low false negative error ratio and the high recognition ratio by color clustering which makes use of the position information and the similarity among homogeneous cells, and by variable size block in proportion to importance ratio of the information.

[가시리]의 신석을 위한 어문학적 연구-[가시리 소설]에의 의의를 중심으로

The most beautiful poem of Korea Dynasty,「KasiliJ has been interpreted and analysed by many scholars. But there remain many problems yet. It is due to the particularity of the original text. The poem [Kasili] was recorded by the old Korean letters of Lee Dynasty, but before that, this poem has been descended from one hundred or some more years before by oral traditions. The most important problems are the disregarding of the value of sound symbolism of the poem and the character of music in the poem. This is because it was written by the soundless letters. The chief problems in the interpretation of [Kasili] are as following. 1) 선하면 They insist that it means to dislike someone or some foods. But it is not true. Gonversely it means to yearn towards someone or love someone dearly. It means to yearn towards someone as if people drew someone's charming feature in their minds. Grammatically, it is the haplology as 「선하면」(sohorn->sohn) Nowadays they pronounce「선 : 하면」 as a long vowel sound. 2) 아니올세라 They insist it means to be afraid of his not coming. , But it is not true. In my opinion, this is the ironical expression in the sentence style. It means, “Will he not come again?" That is to say, “If he (my lover) dearly yearns towards me, he will come again surely”. Therefore 3rd stanza is the sentence of repulsion. Following is my interpretation for this poem. 1st stanza… Are there any reasons for him to leave me? Are there any reasons for him to leave me alone? Will he leave me forever? 2nd stanza… How can I live alone without you? Does he have any reasons to leave me alone to live? 3rd stanza… If I want to hold you not to leave me, it is possidle for me to hold you. But if your mind is far from me, it is of no use to hold your body. In the proverbs and siz(the type of literature of Lee Dynasty), following expressions can be seen at times. If the affection and feeling for someone are true and close, the distant interval doesn't matter. But if the affection and feeling for someone is not true, however nearer place it may be, we cannot but feel long interval. So I believe that if you yearn towards me truely, you (my lover) can come to me surely. 4th stanza… Restraining my sorrowful mind, I see you off. Only I want you to come back to me directly. '

가족력이 있는 만성정신분열증 환자의 인간조직적합성 항원(HLA)

강헌구,강병조 大韓神經精神醫學會 1988 신경정신의학 Vol.27 No.6

The authors studied the frequencies of HLA antigens (A,B,C and DR) in 20 chronic schizophrenic patients who had one or more schizophrenic patient(s) among their first degree relatives. The data of these study subjects were compared with those of patient controls and normal controls. The patient controls were composed of 20 chronic schizophrenic patients who had no family history of schizophrenia HLA-A, B, C antigens of normal controls came from 196 healthy Korean volunteers and HLA-DR antigens came from 205 healthy Korean volunteers. The diagnoses of schizophrenics were made according to RDC and Family History-RDC. The results were as follows: 1) The frequencies of B??,B??,DR₃and DR?? antigens were significantly higher in total schizophrnic patients than the control group. 2) The frequencies of A₃,A?? and B??, DR?? antigens were higher in schizophrenic patients with family history than the control group. Especially, the frequency of DR antigen was the highest. 3) The frequencies of B??,C??,DR₂,and DR?? antigens increased significantly in schizophrenic patients without family history. 4) DR?? is the only antigen that showed significantly higher frequency in patients with family history than those without one. 5) Consequently, these results suggest that DR?? locus is probably related to genetic or biological marker of Korean familial chronic schizophrenics
