Specimens of the ten ovulid species were collected from Jeju Islnad, and identified as followed: Pellasimnia angasi (Reeve, 1865); Phenacovolva pseudogracilis Cate & Azuma, 1973; Phenacovolva rehderi Cate, 1973; Crenavolva leopardus Fehse, 2002; Diminovula coroniola (Cate, 1973); Diminovula stigma (Cate, 1978); Diminovula whitworthi Cate, 1973; Primovula roseomaculata (Schepman, 1909); Prionovolva ericae Cossignani & Calo, 2002; Testudovolva nebula (Azuma & Cate, 1971). These species are new to Korean Malacofauna, and described with the illustrations for the shell morphologies.

Three Ovulid species collected from Jeju Island were identified as Habuprionovolva aenigma (Azuma & Cate, 1971), Habuprionovolva basilia (Cate, 1978) and Diminovula kosugei (Cate, 1973). This is the first record from the Korean waters, providing a description of the species with illustration for the shell morphology.

This study aims to give a syntactic and semantic analysis of the phe- nomenon of Quantifier Floating in the framework of Generalixed Cate- gorial Grammar. Floated quantifiers like neys-i as in Hakayngtul-i neys-i swul-ul masyessta are syntactically analyxed as VP modifiers(VP/VP), and semantically as involving nominalixed properties. Related forms like neys(NP/NP) and neys-ul(TV-TV) are also given rigorous syntactic and semantic analysis. A successful anaysis sheds light on the possiblity of using Categorial Grammar, which is subject to adjacency principle, for the (computer) processing od Korean.

The purposes of the study were (1) to seg-ment the female college apparel market based on fashion life style and (2) to develop a pro-file of each segment regard to self-concept, shopping orientation and patronage behavior. The data were collected through questionnaire by random sample of 526 female college students. By cluster analysis of lifestyle factors, three groups were identified, (fashion leaders, fashion followers and fashion aversion) Three groups were then compared through multivariate analysis of variance and chi-square statistics on 10 self-concept variables, 6 shopping statistics on 10 self-concept variables, 6 shopping orientation factors and 1 patronage behavior variable. Significant difference were found among the three groups on all these variables which indi-cate that fashion lifestyle can be a useful base for segmenting female apparel market and these groups are unique in terms of self-con-cept, shopping orientation and patronage behavior.

There are many studies about optimization using genetic algorithm and desirability function. It's very important to find the optimal value of something like response surface or regression model. In this study I ind~cate the problem using the old type desirability function, and suggest the new type desirabhty functton that can fix the problem better, and simulate the model. Then I'll suggest the form of desirability function to find the optimum value of response surfaces which are made by mean and standard deviation using genetic algorithm and new type desirability function.

Recursive formulas have been effective in solving the equations of motion for large scale constratined mechanical sys-tems. However, derivation of the formulas has been limited to individual terms in the equations of motion, such as veloci-ty, acceleration. and generalized forces. The recursive formulas are generalized in this paper. The velocity transformation method is employed to transform the equations of motion from Cartesian to the joint spaces. Computational structure of the equations of motion in the joint space is carefully examined to classify all necessary computational operations into sev-eral categories. The generalized recursive formula for each category is then developed and applied whenever such a cate-gory of computation is encountered. Since the velocity transformation method yields the equations of motion in a compact form and computational efficiency is achieved by generalized recursive formulas, the proposed method is not only easy to implement but is also efficient. A library of generalized recursive formulas is developed to implement a dynamic analysis algorithm using backward difference.

In terms of the maritime accident prevention, risk analysis at targeted warterways is important for planning safety waterways. This paper analyzes the maritime accidents probability in the Mokpo waterways, South Korea, based on the IWRAP(IALA Waterway Risk Assessment) of the quantitative accident probability tool. Vessel collision probability cate is calculated by vessels meeting direction, using IWRAP. This paper contribute to advance improvement of vessel traffic service by VTS sector providing vessel fairway risk data.

This study was carried out to establish the reasonable level of nitrogen (N) fertilization based on soil nitrate nitrogen $(NO_3-N)$ content for cucumber (Cucumis sativus L.) under plastic film house. Cucumber plants were cultivated with standard and free N fertilization in eight soils which had various amount of $NO_3-N$ ranging from 67 to 343 mg/kg. The yield of cucumber was in the range of 1006 to 2369 g/plant depending on the nitrogen supplying capability of soils. The amount of $NO_3-N$ in the soil was negatively correlated with agronomic efficiency (AE) and N use efficiency (NUE). The critical level of soil $NO_3-N$ content for cucumber in N free fertilization was found to be about 260 mg/kg in Cate-Nelson analysis of variance between soil $NO_3-N$ and AE or NUE. Also the same critical soil $NO_3-N$ content was found in the yield and amount of N uptake of cucumber under N free fertilization. A standard N fertilization was required when soil $NO_3-N$ content was below 70 mg/kg. The optimal application rate of N fertilizer for cucumber in the soils containing $NO_3-N$ between 260-70 mg/kg could be recommended by the equation Y=-1.032X+269.2 (Y: N fertilization rate, kg/ha; X : soil $NO_3-N$ content mg/kg).

In this paper, we designed double gate(DG) MOSFET structure which has main gate(MG) and two side gates(SG). We have simulated using TCAD simulator U .WOSFET have the main gate length of %m and the side gate length of 70nm. Then, u'e have investigated the pinch-off characteristics, drain voltage is changed from 0V to 1.5V at VMG=1.5V and VSG=3.0V. In spite of the LMG is very small, we have obtained a very good pinch-off characteristics. Therefore, we know that the DG structure is very useful at nano scale.
