Today's liquor culture in Korea is basically divided into a general liquor culture and a functional liquor culture. In particular, the market of the latter has been going through a rapid change. In the previous days, it was a crop for a special purpose or a fruit which was mostly used to make liquor but now, many other regular crops are being used in the liquor market. At present, while the demand for Makgeolli has risen sharply, the designs of Makgeolli bottles have never satisfied needs from consumers nor the trends in the consumer market. As a result, Makgeolli industry should come up with new designs for the bottles immediately if it dose not want to lose in a competition with other liquor products. The study has looked into existing designs of Makgeolli bottles, investigating how the designs have changed over the past years and how competitive they are in the market. Based on results from the investigation, the study focuses on finding out designs which would fit the trends in the consumer market to develop Makgolli bottles which would be equipped with both functionality and practicality. In other words, to make Makgeolli survive in these rapid changes in the liquor market, the study works on offering a Makgeolli bottle design which is appropriate for certain characteristics of Makeolli and also competitive over other liquor bottles.

The purpose of this study was to develop a multipurpose incubator, without the gas cylinders (bottles) which are required for $H_2$ and $CO_2$ supplementation. In our bottle-free multipurpose incubator, the $H_2$ and $CO_2$ were generated by chemical reactions induced within the chamber. The reaction between sodium borohydride and acetic acid at a molar ratio of 1:1 was used to generate $H_2$, according to the following formula: $4NaBH_4+2CH_3COOH+7H_2O{\rightarrow} 2CH_3COONa+Na_2B_4O_7+16H_2$, whereas the other reaction, citric acid and sodium bicarbonate at a 1:1 molar ratio, was used to generate $CO_2$, according to the following formula: $C_6H_8O_7+3NaHCO_3{\rightarrow}Na_3(C_6H_5O_7)+3H_2O+3CO_2$. Five species of obligate anaerobic bacteria, one strain of capnophilic bacterium, and one strain of microaerophilic bacterium were successfully cultured in the presence of their respective suitable conditions, all of which were successfully generated by our bottle-free multipurpose incubator. We conclude that, due to its greater safety, versatility, and significantly lower operating costs, this bottle-free multipurpose incubator can be used for the production of fastidious bacterial cultures, and constitutes a favorable step above existing anaerobic incubators.

'Mantari' is a new variety of oyster mushroom for bottle culture. It was bred by crossing monokaryons isolated from 'DM11732' and 'Chunchu-2ho'. The optimum temperature for the mycelial growth was $26{\sim}29^{\circ}C$ on PDA medium, and that for the primordia formation and the growth of fruiting body of 'Mantari' on sawdust media was $18^{\circ}C$ and $16^{\circ}C$. It took 32 days to finish spawn running, 4 days to finish primordia formation, and 3 days to finish fruiting body growth in the bottle culture. The fruitcharacteristics: the pileus was round and gray-black in color, and the stipe was long, thin, and light gray in color. The yield per bottle was 179 g/900 ml and was 5% higher than that of the control variety (Chunchu-2ho). The physical properties of the fruit body were as follows: springiness, cohesive, gumminess, and brittleness of the stipe tissue were 96%, 76%, 160 g, and 15 kg, respectively.

Oyster mushrooms are one of the most popular edible mushrooms in Korea. The 'Santari' cultivar bred in this study, which belongs to the species Pleurotus pulmonarius, is a new oyster mushroom cultivar for bottle culture. It was bred by mating monokaryons isolated from 'GMPO20404' and 'Hosan'. The optimum temperature for 'Santari' mycelial growth was $26-29^{\circ}C$ on PDA medium, and the temperatures for primordium formation and for growth of the fruit body on sawdust medium were $22^{\circ}C$ and $20^{\circ}C$, respectively. It took 34 days to complete the spawn run, 3 days to form primordia, and 3 days to finish fruit body growth in the bottle culture. The fruit body pilei were round in shape and brownish, whereas the stipes were long, thick, and white. The yield per bottle of 'Santari' was 172 g/1,100 mL, which was 43% higher than that of the reference cultivar ('Hosan'). The springiness, cohesiveness, gumminess, and brittleness of the stipe tissue were 87%, 82%, 193 g, and 16 kg, respectively. These physical property values of 'Santari' were lower than those of the control cultivar, except for the cohesiveness.

The present study addresses the tea utensils and tea drinking methods seen in tomb mural paintings of Song, Liao, Jin, and Yuan, which were Koryo's foreign exchange countries. The paintings illustrate the pointing tea method, which was popular during dynasty times. Tea utensils observed in the paintings include a tea mill, mill stone, and tea pestle necessary for making cake tea into powder. The tea stove and boiling bottle are depicted as being required to boil water. Some mural works vividly depict how a tea drinker pours hot water from a boiling bottle into a cup with a stand, mixes it with a tea spoon, and whisks tea powder for foaming with a tea whisk. The tea drinking method of the Southern race Han is also similarly described in the tomb mural paintings of Liao, Jin, and Yuan from Northern nomads. The distribution of tea culture had an enormous influence on the development of tea utensil manufacturing methods. The significance of this study is that these findings can be used as basic data to provide food culture insights into Koryo celadon tea utensils.

The drinking manners of the modern generaton were reviewed based on historical records. First, for reasons of health, we should reject the drinking from the same cup as others in reciprocation. Second, if the other people are older or younger brothers above the same level, pouring with one hand is all right, but if 5 years older or more, or stranger, grasp the bottle in two hands in the following manner. With the right hand under the bottle, and the left hand supporting its side, carefully pour wine not to show the palm of the hand. Third, ladies, also, can drink freely at the same table, but if people of the opposite sex are sitting together, they should pour with two hands to convey the meaning of courteous treatment. Fourth, because the level of our living is not two high, we must not order more them we can use, so that when we are finished, there will be no remainder.

This research was conducted to survey the feeding methods of Korean women. The survey was executed for 355 mothers bringing up a child below 24 months in some part of Seoul in Korea from April to May, 1990. Incidence of breast feeding was 29.1% of the interviewed mothers in Seoul, which showed lower percentages than those of previous surveys. This research proved the major influencing factor generally depended on its mother rather than babies or labor condition. For example, the higher income and the higher educational degree of its mothers, they tended to prefer the bottle feeding to the others. Generally mothers knew the informations of infant nutrition very well, 84.5% of the interviewed mothers in Seoul had the opinion of 'breast feeding is better', but their knowledge actually didn't work. The source of mothers‘ informations on the infant nutrition showed the books and magazines, friend and relatives, grandmother were many by the order. But there were some discrepancies between the actual and needed source of information; i.e. mothers in Seoul mostly(44.8%) wanted to acquire their informations from mass communications. The reason of breast feeding showed 'for baby's health' was the greatest, and then 'immunity of breast milk' and 'baby's emotion' were great by the order, and the reason of bottle feeding showed 'not enough breast milk' was the greatest. There were no problems in feeding attitude and position of breast feeding, but there were problems in feeding volume, consistency of formula milk and feeding position of bottle feeding.

In this study we carried out to find suitable nutrient supplement of corncob as a main carbon source for bottle culture of oyster mushroom. Data from chemical analysis of Kapok seed cake(KP) treatment showed 20.2 of C/N ratio, $0.28g/cm^3$ of bulk density and 74.2% of porosity. Mushroom yield of KP treatment is 158g/bottle that is similar to control(150g/bottle). However, the price of KP is 400 won/kg that is cheaper than 550 won/kg of cotton seed cake(CS). The highest REV(relative feed value) also was observed KP treatment. A further study is required determine practical animal performance by feeding the corncob-based KP.
