The purpose of this study is to provide the basic guideline of the archite-ctural planning and design of the women's hospital for optimizing the area compostion and spatial allcoation. The method of this study is to investigate and analyze the functional spatial composition based on the area composition and spatial allocation of the 4 departments space in women's hospital through a analysis of 9 cases study. Data collecting skills such as drawing documents analysis, field survey and observation were used to examine of the present facility condition. Hence this research is to grasp the present condition of department of the women's hospital, to inquire the area composition and spatial allocation. Finally, The derived important factors are expected to use as the basic data at the time of planning for the space programing of design women's hospital.

Fast and accurate distillation design requires a model that significantly reduces the problem size withour loss of accruacy is especially suitable for rela-time applicatoins. the reduced order model is obtained by use of Principal Component Anlysis(PCA). Then the extended Kalman filter and the Recursie Predictiuon Error(RPE) mehtod are appliced to identify the model parameters and the feed compostion form the measuremenets of the coumn. as a consequence it is found that the model reduction thechique can account for the dynamics of the rigorous distillation model and not only the model parameters, bu also the feed compostion can be identified efficiently. this technique is applied to industrial operation data verify the performance of reduced order model.

Yangdan Cave displays as a Vadose Cave rathre than a Phreatic Cave due to its fluvial activated ramnants of the cave beds and walls. Geochemistry experiments of the speleothem (stalactite and stalagmite)were generated in order to find out the cave material characteristics using XRD. The results present that the composition of the cave materials consists of Calcite, Dolomite, Quartz, K, K-Feldspar. Plagioclasc, Illite, and Kaolinite. These materials commonly exhibited less mineral composition than other caves. In terms of calcite compostion of the cave the upper cave materials (d=3.049) contain less than lower cave materials (d=3.055). Finally the calcite compostion of the cave materials between stalactite (d=3.055) and stalagmite (d=3.054) displays simillar values.

Experimental investigation has been carried out to study the characteristics of the various grade limestones in Samtaesan formation with the fundamental test (mineral compostion, thermal decomposition and etc.) and intrinsic reactivity test. It was shown that belite formation in low grade limestones is faster than high grade limestone, but alite formation has a contrary.

The number of vehicles employing diesel engines is rapidly rising. Accompanying this trend, application of an after-treatment system is strictly required as a result of reinforced exhaust regulations. The Diesel Particulate Filter (DPF) system is considered as the most efficient method to reduce particulate matter (PM), but the improvement of a regeneration performance at any engine operation point presents a considerable challenge by itself. Temperature, gas compostion and flow rate of exhaust gas are important parameters in DPF evaluation, especially regeneration process. Engine dynamometer and degment tester are generally used in DPF evaluation so far. But these test method couldn't reveal the effect of various parameters on real DPF, such as O2 concentration, amount of soot and exhaust gas temperature. This research has studied the possibility using dump combustor that used to take an approach lean premixed combustion in gas turbine for a DPF power and optimized. It is possible that utilize the system as DOC (Diesel Oxidation Catalyst) and SCR(Selective Catalytic Reduction) assessments test as well as DPF evaluation

The present study was to formulate a computer program to provide a menu based on a food preference survey of families in urban areas. A food preference survey was conducted by individual direct interviews of infants, children and old people in this study. In case other's food preferences were available, food menus considering all age groups could be made. Database III PLUS package was utilized for this study. The dBASE was loaded with a food compostion table of 339 different food items, along with data for amino acids and fatty acids for 171 and 43 food items respectively. Food preference, unit of food, and recommended dietary allowances were also incloded. This meun program system calculates nutrients in selected foods, and menu assessment was composed of several factors inculding energy ratio of carbohydrate : protein : fat, amino acid score, limiting amino acid, polyunsaturated fatty acid/saturated fatty acid(JP/S) ratio and Ca/P ratio.

The Wooro cave speleothem displays comparatively very less developed characteristics due to its unactive fluviation, less soluable carbonate rocks, 3nd disconnected short voids. The Weoro cave consists of stalactite, stalagmite, flowstone, rimstone, and moonmilk, however, it is not exhibite soda straw, cave pearl, pisolites, curtain, drapery, cave flower, anthodite, cave coral, helictite. heligmite, boxwork, pendent and, cemented shield. The main cause of the underdevelopment speleothem of the Wooro cave probably less peneturated waters or less calcite compostion of the carbonate rocks.

Evaluation and comparison for the performance on the contracting-out became possible after the introduction of the performance indicators(PIs) in 2012 in Korea, And local governments and private companies are utilizing them as evaluation data to enhance the performance of the contracting-out. Several revisions on performance indicator were carried out by expert group on contents validity of PIs, But the review of the composition validity of PIs was not sufficient. In this study, the applicability, distinction ability and composition validity of PIs is evaluated by statistical method. From the results, Improvement of indicator is required in order to increase the interrelationship among indicators to enhance the compostion validity of indicators related with operation, sludge and water reuse.

Two Rice cultivars , a high yield variety of Cheongcheong and a Korea native kind of Chucheong were grown in paddy. 1$\mu\textrm{g}$ and 10$\mu\textrm{g}$ of aflatoxin B1 and Aspergillus flavus (106 conidia/ml) were inoculated at milk stage. At harvest, kernels from the inoculated plant showed slightly lower ripening rates and 100-grain weight than did those of controls. The nutrient and fatty acid composition of unpolished rice of inoculated group were similar to those of controls and difference between the control and inoculated group were not significantly different.
