Park, Jae-Ick. 2002. Vowel Harmony in Eastern Bantu Verbs. Studies in Phonetics. Phonology and Morphology 8.1. 101-115. This study proposes that vowel harmony in Eastern Bantu verbs can be accounted for by imposition of the radically-specified [-hi, +Io, +rd] features in constraint-based approach. These features are supported by the default vowel insertion for syllabification of consonant-ending loanwords in these languages. Vowels /e, o/ have a specified [-hi] feature and the specification itself contributes to the behavior in the mid-vowel harmony. The systematic replacement of CeCo by CeCu in Eastern Bantu verbs has been viewed as exceptional or disharmonic in various previous studies. Viewing low vowel /a/ as opaque in previous studies has also been part of the problem in vowel harmony in Eastern Bantu verbs. The radically-specified features proposed in this study are very effective to solve these problems as well as to explain the previously accepted behavior. Three constraints with regard to the specified features interact themselves to produce optimal output for the current vowel harmony in Eastern Bantu verbs. A mid vowel starts (aligns) verb-root-initially and extends all the way to the end of the verb unless it is blocked by a vowel with a specified feature such as /u/ and /a/. (Kosin University)

The main purpose of this paper is to identify the enlargement measures of private sector involvement in the urban land development. To delve into the realities of private land development, this paper is organized into five chapters. To alleviate the problems of the public regulation and monopoly, the private sector should be encouraged to participate the urban land development process. In reality, the enlargement measures of private sector involvement in the pubic sector development can be considered in the present three development systems as follows; the collaboration system between the private and the public sector, the third-sector system and the co-development system among landowners. The former two can be applied to the larger scale development projects while the latter to the smaller ones. In conclusion, the private sector involvement in the urban land development should be enlarged in order not only to combine the vigour of private sector with the public development system but also to meet the diverse needs of the people through the collaboration work between the private and the public sector.

Lindera obtusiloba seed oil was extracted by diethyl ether and fractionated into neutral lipids, glycolipids and phospholipids by silicic acid column chromatograpy. Fatty acid composition of each fraction was examined by gas chromatography. The results obtained were summarized as follows; 1. The proximate chemical composition of Lindera obtusiloba seed was 13.0% in crude protein, 53.5% in fat, 14.4% in carbohydrate and 1.8% in ash content. 2. The values of acid, saponification, iodine and peroxide from Lindera obtusiloba seed oil were 0.93, 269.50, 61.30 and 120.30, respectively. 3. The total lipid was composed of neutral lipid 93.38%, glycolipid 4.52% and phospholipid 2.10%. 4. The fatty acid composition of total lipids were 38.34% in lauroleic acid, 33.23% in lauric acid, 7.75% in oleic acid, 5.38% in mylistoleic acd, 4.69% in capric acid and 3.89% in caproleic acid. 5.

Among zero-suppression (AS) algorithms proposed for synchronous stream cipher system, ZS-1 has the difficulty on the implementation of the stream cipher system, ZS-2 has a weakness of channel error propagation, and ZS-3 has the complexity on the hardware. Because each algorithm must be chosen carefully to the application system, in this paper, we propose a criterion of the system adapted from the simulated results on the parameter changed.

단섬유강화 무기 복합재료의 파괴인성에 관한 연구

신익재,이동주 영남대학교 공업기술연구소 1999 工業技術硏究所論文集 Vol.27 No.1

The objective of paper is to study the reinforcing effects of fiber volume fraction and aspect ratio in short-fiber filled ceramic matrix composites. The parameters of fracture mechanics, K and J are applied to assess fracture toughness and bridging effect. It is found that fracture toughness is greatly influenced by the fiber bridging, Also, the nonlinear fracture analysis such as J-integral is more effective than LEFM for short-fiber reinforced ceramic matrix composites. For the reinforcing effects as functions of fiber volume fraction and aspect ratio, fracture toughness is increased rapidly with fiber volume fraction and aspect ratio as expected.

A fuzzy classifier which needs various analyses of features using genetic algorithms is proposed. The fuzzy classifier has a simple structure, which contains a classification part based on fuzzy logic theory and a rule generation part using genetic algorithms. The rule generation part determines optimal fuzzy membership functions and inclusion or exclusion of each feature in fuzzy classification rules. We analyzed recognition rate of a specific object, then added finer features repetitively if necessary to the object which has large misclassification rate. And we introduce repetitive analyses method for the minimum size of strings and population, and for the improvement of recognition rates. This classifier is applied to three examples of the classification of iris data, the discrimination of thyroid gland cancer cells and the recognition of confusing handwritten and printed numerals, each sample numeral is classified into one of the groups which are diveded according to the sample structure. The fuzzy classifier proposed in this paper has recognition rates of 98.67% for iris data, 98.25% for thyroid gland cancer cells and 96.3% for confusing handwritten and printed numerals.

대나무를 纖維工業의 原料로 利用하기 僞하여 竹粉 시멘트의 水化反應을 木質-시멘트 및 製紙슬러지-시멘트와 比較하여 測定하였다. 水化反應 促進을 위한 化學添加劑로는 CaCl_2와 MgCl_2 그리고 NH_4Cl을 시멘트 重量當 3%를 各 試驗片에 添加하였다. 또한 無處理時의 各 試驗片과 化學添加劑를 使用한 名 試驗片의 結晶形態 및 結晶構造를 調査하기 僞하여 走査電子顯微鏡으로 斷面을 測定하였다. 無處理時의 境遇, Henon bamboo, Moso bamboo 및 Giant timber bamoo는 전혀 水化反應을 보이지 않았으며, 化學添加劑를 利用한 境遇에는 木質水準으로 水化反應이 나타나 竹紛을 利用한 시멘트와의 水化反應은 使用해야 함을 알수 있었다. This study was examined on hydration of bamboo meal-cement composite. In a separate experiment, the heat of hydration generated from the bamboo meal (wood meal and paper sludge) - cement - water system was measured, and Moslemi's inhibitory index was caluated from the results. To improve the hydration of bamboo meal- cement, a series of experiments were conducted with the addition of various chencal additives such as calcium chloride(CaCl_2 ), magnesium chloride( MgCl_2 ) and ammonium chloride (NHCl) The amount of chemical additives was 3% based on the weight of the cement. A scanning electron microscope (SEM) was used to examine the crystallization of cement and bamboo meal ( wood and paper sludge ) - cement composite. These species , Henon bamboo, Moso bamboo and Giant timber bamboo were proved to be highly inhibitory in a series of hydration tests. The addition of chemical additivies, especially calcium chloride and magnesium chloride, appears to enhance compatibility in bamboo meal-cement-water composite.

In order to evaluate characteristics of bast fiber, the types and the cell wall properties of various bast fibers originated from Broussonetia kazinoki Sieb. Morus alba var, romana Loddiges, Edzeworthia papyrifera Sieb. et Zucc. and Wikstroemia irichotoma makino. In the other hand, Broussonetia kazinoki Sieb. et Zucc. and Wikstroemia trichotoma Makino. The pits were not find in fiber surface of bast fibers from 4 species, but the presence of secondary wall was surely confirmed. The cell wall structure of bast fiber was a little different from that of wood fiber.
