The purpose of this study is to grasp the retention status of household items for children and the real condition of storage targeting dual career families of living in 3-bedroom apartment. To do this, a field survey was conducted by having subjects as 30 households of conforming with the requirements. This led to understanding kinds and quantities of household items for children inside the residence and to surveying the present status on household items of being stored by room, thereby having analyzed a difference in household items according to children's age. The survey results are as follows. First, the household items for children within dwelling were indicated to be totally 145 detailed items. In the quantities of the detailed items, a great difference was shown by age in clothes, books, teaching aids, toys, and stationery. Second, as a result of examining a place of being stored the household items for children, the household items in great quantities were found in living room, room 1, and room 3 even in addition to room 2 that is children's room. Third, in consequence of looking at the storage status of household items for children by age level, it could be known that very different household items are being used depending on children's age, and that a place of storing household items is much varied by age. This outcome could lead to being capable of knowing that one-child families living in 3-bedroom apartment are using every room focusing on child, and that child's household items are being disorderedly stored in each space, thereby requiring the systematic storage plans so much that reflect the real situation.

This study investigates urban household consumption patterns for clothing items in different income cohorts through the analysis of an Almost Ideal Demand System (AIDS) model. Korea quarterly time-series statistics data for urban household expenditures from 1990 to 2013 analyzed household demand. The price and total consumption expenditure elasticities of 4 clothing items (outer wear, shoes, clothing related services and other miscellaneous clothing) for 7 income cohorts were estimated to investigate the clothing consumption patterns of different income cohorts. The study results show that the different household income cohorts have different consumption patterns for clothing items. The elastic demand of total consumption expenditures in the lowest household income cohort suggests that they consume clothing items as luxuries while other households mostly consume them as necessities. The price elasticity for all household income cohorts and clothing items (except the highest household income cohort and outer wear) was found to be elastic. The highest household income cohort had an inelastic price demand for all clothing items that implied a less sensitive clothing consumption change for the clothing price change than other households.

The purpose of this study is to investigate household Items and storage of kitchen and to suggest basic data for the desirable storage space. For the study, the samples were taken from 30 families living in 3-bedroom apartment. The personal interview and physical trace method were used to analyze the types and quantities of household Items and the storage conditions in kitchen furniture. The result was as follows : first, a total of 210 types of household Items were found in the kitchen, and the items ranged widely in purpose, from cooking and dining tools, hygiene products, and general household goods, which indicate that a variety activities in addition to cooking and eating are performed in the kitchen. Second, regarding the quantities of household Items, the majority of them were used for cooking and dining. Also the types and quantities of household Items varied according to the age of the child. Third, regarding storage of household Items in the kitchen by furniture type, the majority of the items were stored in the wall cabinets, base cabinets, and countertops and, as a storage method, simple 'placement' was most common. This suggests there is lack of three-dimensional storage in the kitchen. The findings show activities and storage in the kitchen space vary according to the age of the child, and household Items are stored by using several common methods.

This study investigates the over time changes in the ownership of kitchen items, electric or non-electric, and examines the patterns of the usage and ownership of the items after categorizing them as followings: cooking appliances, kitchen appliances directly related to storing food, food processing kitchen items, and dining items. The research findings are that refrigerators and rice cookers, among the electric items, had spread to almost every households by 1990s and at the same time about thirty non-electric kitchen items had been used. Refrigerators had been used by more than 100% of the households by 2000, and on top of that, twenty or more electric kitchen items such as Kimchi fridge and freezer had been used. In the case of non-electric kitchen items, approximately 50 to 70 sorts of them are used, which indicates an increase than in 1990s. Rice cookers and gas stoves, among cooking appliances, are recognized as the essential item, and they are actually frequently-used items. As to kitchen appliances related to storing food, each household owns one of the refrigerators and Kimchi fridges, and again they are both the frequently-used. As far as food processing kitchen items are concerned, each household owns at least one or more blenders and hand blenders, six or more knives, and five or more pans. Each household owns seventeen or more rice bowls and soup bowls and twenty-four or more plates. Small plates are more frequently used than large ones.

This study investigates the effects of changes in price, total consumption expenditures and economic sitations on Korean household demands for clothing and footwear using time-series data. The clothing and footwear category was reclassified as clothing, footwear and clothing services items for the demand analysis. This study utilized the Linearized Almost Ideal Demand System (LAIDS) model to analyze household demand. The results indicate that price and total consumption expenditures are significantly related to Korean household consumption expenditure allocations for clothing and footwear items. The effects of the IMF bailout crisis in 1997 and the global financial crisis in 2008 on household expenditure shares for clothing and footwear items were very weak and statistically insignificant. All the demand elasticities were estimated with respect to total consumption expenditures and prices. Clothing was expenditure elastic (greater than one) and other items were classified as inelastic. All the own price elasticities of demands were negative (other than clothing). Through the estimations of cross price elasticity the relationships between the demands for items and other item prices were evaluated (i.e., substitutes and complements).

For this study, fire tests were performed targeting household items (Sofa, Drawer, Refrigerator, Washing machine) using a large cone calorimeter (Large Scale Cone Calorimeter, LSC). The data were obtained focusing on the fire characteristic of the data when the actual fire occurs. The study results showed the following mean HRR of the household items; drawer 2843 KW, sofa 2939 KW, washing machine 719 KW, refrigerator 2907 KW, and THR is found in sofa 2202 MJ, drawer 1559 MJ, refrigerator 1193 MJ, washing machine 627 MJ. From the result, it could be found that the sofa can cause significant heat generation when the fire occurs, and the flashover tendency was found relatively high in compartment fire. In addition, a weight of the four our household items was reduced sharply in a similar time (20min before and after) degree after ignition. The drawer and sofa which has a high heat release can be considered to speed up the fire spread as their weight decrease rapidly and showed relatively weak to the fire compared to the refrigerator and washing machine.

This study examined how the differences in household characteristics influence consumer expenditure patterns. The Price-Scaling AIDS model with household income and expenditure survey data were used for the analysis. The results showed that the income elasticity of the service items is greater than non-service items, indicating an increase in higher demand of service items with the same increase in household income. The household expenditure patterns vary according to the commodities, holding age and income level. The so-called traditional pattern, which emphasizes spending for non-service items, changed to the one with a higher expenditure ratio for service items. Such a change in household expenditure patterns naturally derives the expansion of the relevant service market; hence, the growth of the related service industry. This highlights the need to formulate an appropriate response from the supply side that deals with the changes in the service market.

The purpose of this study was to investigate the working married women's perception on the effect of work on household economy. The household economy was examined in three aspects; income, assets, and consumption patterns, along with the contribution and the satisfaction of working married women with respect to their income by work Four hundred thirty working married women with the first child of less than middle school were surveyed, with questionnaires from March 25 to April 22 of 2005, and analyzed with descriptive statistics. The results were as follows: the reasons of working married women for work were making an affluent living, showing their ability, wanting for work, and making a living in order. The perceived degree of their income contribution to household income was on the average about $42.53\%$. They perceived the spending in time-saving consumption items, child-rearing consumption items, and personal consumption items to be decreased, if they were not working. Their work was helpful in saving, insurance and investment, debt payment, money for old life, money for housing, money for emergency. About $69\%$ of working married women perceived their income contribution to their household income as being high.

The several sacrificial rites foods in east coast areas Kyungpook province, Pohang, Youngduk, and Uljin, were surveyed. For the anniversary menorial service, the food items in these reas were mainly rice(Bab'), soup(Guk'), stew(Tang'), fruits, neats and fishes, alcohol which are the typical food items for any other area in Korea. In this east coast area, the seaweed was used more often than in inner land area for this rite food. Four kinds of rice cake(Ddeok' or Pyun') were surveyed for this rite. For the baked food item(Geuk'), the fish squid and the Alaska pollack were used frequently for Geuk'. For the fruits dishes, 3 items were the basic. Tang' which was made with the various fishes, were used very frequently. For the religious memorial service for god to guard the household, the displayed food items were different from depending on the type of the god to guard the household, however, the general display of the food items was almost the same as in land area. For the winter sacrificial rite, the boiled rice(97%) and Bakpyun' was used mostly for the Ddeok'. For the Guk', bean sprout was used mostly, however, the seaweed soup was also used(7%). The fish Tang' was the most used one(35%). For young-deung-je', which implied th safe guard of the household, most of the food items are similar to those of the normal sacrificial rite, however, the fishes which were not fishy were used. The housekeeper arranged the rite to catch a large amount of the fishes and to hope the wellbeing of the household, Poong-yer-je is so called as Byul-sin-gud'(a practice of an exorciser). The food items for this Poong-yer-je' were almost similar to those of the winter sacrificial rite, however, Geulpyun' was mostly used for the Pyun'. In addition that, the red-bean Si-ruddock', Baekpyun', and Yung-ddock'(a dragon cake) were used for this rite, At the end of the sacrificial rite, Yong-ddock' was served to the dragon king which was believed in sea.

Food waste has increasingly become a global issue of concern among the researchers and policymakers due to its significant environmental and economic impacts, and other associated unsustainable use of resources, including water resources. While food wastage occurs at each stage of the supply chain with food loss at the upstream and food waste at the downstream, the impacts of food waste occurring at the consumption side are enormous due to the accumulated added values. In this study, the embedded water resources, greenhouse gas emissions, and economic loss of household food waste were investigated. The primary granular data of household food waste was collected through direct sampling from 218 selected households of the Buk-gu community in Daegu, South Korea from July 2019 to May 2020. The water footprint, which was based on the water footprint concept, i.e., indirect water use, and GHG emission potential factor for each of the food items were adopted from the literature, while the retail prices and disposal cost were used to assess the economic cost of wasted food items. The water footprint, GHG emission associated with environmental impacts, and the economic cost of 42 major identified wasted food items were conducted. The findings showed that an average of 0.73 ± 0.06 kg/household/day edible food waste was generated among the sampled households, with leafy vegetable, watermelon, and rice responsible for 10, 9, and 4%, respectively, of the total weight of the 42 food wasted items. The water footprint and environmental impact of the household food waste resulted in 0.46 ± 0.04 m³ and 0.71±0.05 kg CO2eq, respectively. Beef, pork, poultry, and rice accounted for 52, 9, 5, and 4% of the total water footprint, while beef, pork, rice, tofu/cheese had 52, 8, 6, and 6% of the total emissions, respectively, embedded in the food wasted. Furthermore, the average estimated economic cost associated with wasted food items was 3855.93±527.27 Korean won, with beef, fish, and leafy vegetable responsible for 21, 13, and 10%, respectively, of the total economic cost. A combined assessment using water-environmental-economic nexus indicated that animal-based food had the highest footprint impacts, with beef, pork, and poultry indicating high indices of 0.3, 0.08, and 0.06 respectively, on a scale of 0 to 1, compared to corn and lettuce with lowest impacts of 0.02. Other food items had moderate impact values ranging from 0.03 to 0.05. This study, therefore, provides insight into the enormity of environmental and economic implications of household food waste among Korean households.
