A survey was conducted of 1,454 customers to investigate dining out behaviors at fast food restaurants of Youido department compound, Myung-dong and Gang-nam district in Seoul, in April, 1988. The results are summarized as follows; The majority, 85% of customers, were aged 14 to 30, consisting of junior and senior high school children, college students and company employees. The reasons given by customers for patronizing fast food restaurants were the following, from most to least frequent; "convenient to dining," "the adequate place for the companionship", "the surroundings and dining equipment are pleasant and hygienic", "to be able to stay as long as I want". The fast foods purchased by the customers were mostly for a between meal snack or ice cream or drink rather than a full meal. The majority of the customers ate the purchased foods at the fast food restaurnats. However, a limited number of female customers preferred to take the packed fast foods to their homes. Tast Preference was a major factor in food selection from available food items. Ice cream, juice, French fried potatoes, salad, fried chicken, rolled rice with laver, and coke were high on the list of liked foods; in constrast, lower preference was for porridge, fish burger, doughnut, chicken burger and rice cake. Preference by food nationality was highest for Korean food, then Western food, Chinese food, Italian food and Japanse food, in that order. Customers offered suggestions for better fast food service, such as lowering the price, greater variety in the menu, increasing the propotion of vegetables and fruits on the fast food menu adn developing fast foods from traditional Korean foods. The customers, in particular, emphasized a need for the development of Korean traditional beverage of malted drink and persimmon punch, as well as mungbean pan cakes and sweet-spicy rice noodles(docbokki), as fast foods.y rice noodles(docbokki), as fast foods.

A Study on the Interface Behavior of Aluminium Alloy Matrix Composites Reinforced with W Fiber. In this study the tungsten fiber reinforced 7072 aluminium alloy martrixcomposites were fabricated using vacuum hot press. The fiber has been aligned on the aluminium alloy sheets and these sheets were bonded with diffustion at 873K and 49Mpa. The behaviors of interface layer and mechanical properites have been investigated as a function of holding time at 873K. Several compounds were formed at the interface layer. These compounds were growing in propotion to holding time. XRD analysis showed that these compounds were $WAl_{12}$ $WAl_5$. The tensile strength decreased as the heat treatment time over 10hr gradually. The ductle fractur mode was turned to brittle mode after heat treatment.

This paper deals with AM-SMMA (Adaptive Modulus-SMMA) adaptive equalization algorithm that is possible to improves the equalization performance using adaptive modulus which is propotional to the output signal power of equalizer in the current SMMA algorithm. The fixed statistic modulus of transmitted QAM signal is used in current SMMA algorithm in order to generate the error signal for updating the tap coefficient of equalizer. The adaptive modulus which is propotion to the equalizer output signal power is used in the proposed AM-SMMA. The computer simulation was performed in order to confirm the improved equalization performance of proposed algorithm. The performance index includes the output signal constellation, the residual isi and maximum distortion that is for the convergence characteristics, the SER. As a result of computer simulation, the residual isi, maximum distortion are better in the small weighting values. But in SER performance is better in the large weighting values.

We studied the effects of intake of the steamed bean powder(SB) and chungkukjang powder(CK) on blood parameters such as glucose, albumin, GOT, GPT, hematocrit, hemoglobin, total-/HDL-/LDL-cholesterol and triglyceride, and blood antioxidant nutrients such as retinol, tocopherols and carotenes in 26 college women. There were 2 groups, one group had 13 participants who consumed 30g SP and second group (13 participants) consumed 30g CK daily for 4 weeks. The study compared before with after SP/CK intake. The average age of the participants was 22.1 years, there were no significant differences between the two groups in terms of all parameters before the study. The energy intake showed no significant differences between before and after SP/CK intake. C(carbohydrate) propotion was reduced, and P(protein) and F(fat) ratio were increased after 4 week intake of SP/CK. Indices of nutritional quality(INQ) of protein(p<0.01), iron(p<0.05), zinc(p<0.05), vitamin C(p<0.05) were significantly increased after SP intake, and those of protein(p<0.05) and zinc also increased after CK intake. There were no significant differences in TG, total-/HDL-/LDL-cholesterol before and after SP/CK intake. The CK intake group showed the reduction only in retinol level in blood(p<0.05). Some students reported the improvement of the constipation and the regularity of the bowel elemination, and some students experienced the prolongation effects on one's monthly days after SP/CK intake. In this study, we could see the effect of improvement in some nutrients intake, but no effect in blood parameters by SP/CK intake for 4 weeks. That reason might be that the participants were healthy young women, or the trail period was not enough long to change.

There are many researches about metrics to measure a quality of Object-Oriented(OO) software. However, most of them have only discussed a concept or properties of metrics, and have not shown the detailed procedure for measuring them. They also define a measurement indicator as a threshold, but it has been influenced on a project size or application domains. In this paper, we propose metrics based on characteristics of OO design such as size, complexity, coupling and cohesion, and use a propotion to an average as the measurement indicator. It is easy to classify classes which have a result above the average, and to predict classes which reduced the quality of OO design. They will be modified to hold the average. Proposed metrics are analytically evaluated by Weyuker's nine properties. They are satisfied with seven properties except two properties co not apply to OO metrics. Also, we design a quality assessment system, ASSOD(ASsessment System of Object oriented Design), to measure the quality of the OO design independent of the platform.

The purpose of this descriptive study was to investigate the determinants of mother's choice of infant feeding method on immediate postpartum period & the breast feeding practice after 1, 2, 3, 4, 5months. The subjects were 170 mothers who were delivered at 2 hospital, 2 OBGY clinics, 1 midwifery in Jinju, the data were collected from Jan. 1 to Feb. 20 of 1991, form each subject at two periods of time ; postpartum 2 or 3 days via interview, 5months via telephone interview. The results were as fellows : 1. The propotion of mother planned exclusive breast-feeding was 66.5%, milk feeding 17.6%, mixed feeding 15.9%, End 38.9% of mothers planned to breast-feed their infants for 4-6moths, 25.7% for more than 12 months. The major reasons for selection of milk feeding method were the presence of mother's job(26.7%), the conditions of breast & milk production(23.7%). 2. There were significant relations between the choice of feeding method & the presence of s job(p<.01), & parity(p<.01). 3. The percentages of subjects that were received education about the advantages & method of breast feeding were 63.5%, 38.2%, respectively, & the informants were mass media, 89.8%, 81.5%. 4. The most of mothers had the knowledge about the advantages of breast feeding. 5. The percentage of mothers that practiced breast feeding on postpartum were 75.9%. 6. The rates of breast feeding practice by duration were more than 5months, 60.5%, 1 month, 27.1%, 2-4 months. 12.3%. 7. The reasons for the stop of breast feeding were the decrease of milk volume(22.9%), the presence of mother's job(17.4%). 8. The duration of breast feeding practice were differed significantly by the presence of mother's job, type of delivery, rooming-in, planned duration of breast feeding, the first feeding time.

In this paper, we analyzed the impact of capital adequacy requirements on the profitability of Korean banks using DOLS model. As a result of the analysis, the impact of BIS capital ratios on commercial and regional banks was different. Demand for capital adequacy has a greater and more significant negative impact on regional banks than on commercial banks. It was shown that bank characteristic variables rather than macroeconomic variables have a more significant effect on bank profitability. In addition, a rise in the BIS capital ratio reduces the profitability of commercial and regional banks, and the higher the ratio of loan-loss provisions, the stronger the relationship. In the case of commercial banks, it is estimated that the demand for capital adequacy did not have a significant impact as they are relatively large and faithful in capital compared to regional banks. However, in the case of regional banks, safer assets need to be selected to meet the BIS capital ratio, and the increasing propotion of these safe assets seems to have a relatively greater negative impact on profitability. Consequency, the financial authorities should consider this results and implement the bank's capital regulation policy.

In Ulrung floral community the growing environments and nutritive values of wild garlic was investigated. The wild garlic, grown for $3{\sim}4\;years$ in community area, were able to develope bulbs. The bulbs with 2 leaves had the highest ratio of propotion as 75.1% of share among the distribution of bulbs with completely developed leaves and 1 leaf-bulbs and 3 leaves-bulbs had 19.6% and 5.3%, respectively. Also the 2 or 3 leaves-bulbs indicated the better growth states in the part of shoot and bulbs than 1 leaf-bulbs, and there was a significant defferences in each growth between 2 leaves-and 3 leaves-bulbs. On the wild garlics we cannot find out insect injuries. However, there was deseases with symptoms of leaf-spots and lesion from May to June. At first it made a small spots on the leaves, followed by senescence at arrounding area of spots, and then it expanded to whole leaf. This pathogenic bacterium was supposed to be a member of Aristastoma. The contents of crude protein, fat, and carbohydrate in each portion of wild garlics decresed in the order of shoot, expanded leaves and bulbs. On the contrary, crude fibers increased in the same order and so it is not suitable for human consumption nutritional value. However, because the shoots of wild garlics have more than the other Allium sp., the shoots will be a good quality food stuff.
