The purpose of this study was (1) to investigate changes in house and kitchen forms and behaviors in the kitchen area of Korean family houses from the Yi-dynasty to the present, and (2) to develop a housing conceptual framework on the basis of the ecosystem approach through analysis of changes in Korean family houses. The documentary research method wad used fro this study. The major findings were that the traditional Korean houses were composed of separate buildings and had various floor levels with the maru(a wooden floor) as the center of the open plan. The introduction of foreign style house forms from the era of enlightenment, in the year 1876 to the Korean war in 1950 changed traditional Korean houses into Korean-western style houses. More recent increased population and urbanization accelerated to change from the traditional Korean house form to an apartment style. At the present time, however, many kinds of house forms, from a highly modernized style with convenient facilities to a primitive style, which cannot even meet the basis needs of daily life, coexist together. The Kitchens in traditional Korean houses had no plumbing, drainage, or work centers. They had simple adobe furnaces which were used for cooking and for heating the ondol, a kind of panel heated floor by which the heat and smoke run under the floor to the chimney. This made the kitchen floor level lower than the floors of other spaces. The residents entered the kitchen through the madang(atrium). The influence of the western style kitchen, the development of technology, and improvements of nation-wide economic status have made today's kitchen space covenient and hygienic. The floor level of the kitchen was raised to the same level of other spaces. Formerly the major function of the kitchen was raised to the same level of other spaces. Formerly the major function of the kitchen space was cooking and heating floors. This had changed, and the kitchen is now, the place for family and social interaction. A housing conceptual framework was developed on the basis of these findings.

The present study showed the advantages of dried Bacillus subtilis culture (DBSC) supplementation on reducing ammonia gas release in the poultry house. In Experiment 1, 65-week-old Hyline W-36 hens were raised in individual wire-floor cages in a windowless house, and divided into two groups of 180 hens each. One group was fed diets without DBSC as the control and another group was fed a diet supplemented with 2% DBSC. In Experiment 2, 2-week-old broiler chicks were divided into 3 treatment groups of 20 chicks each and maintained in individual floor cages. One group was fed the diet without DBSC and other two groups were fed the diet supplemented with 1 or 2% DBSC, respectively. In experiment 1, DBSC consistently reduced ammonia gas release in the laying house (p<0.01) and manure storage facilities (p<0.01). incubation of feces for 1, 2, 3, 4, 5, 6, 24 or 48 hours showed that DBSC consistently reduced ammonia gas release. In Experiment 2, DBSC reduced ammonia gas release in the broiler house; however, DBSC had no effect on total N, urate-N and ammonia-N contents of feces, but it improved cumulative N utilization and decreased serum urea-N concentration when chicks when chicks were fed 1% DBSC.

To cope with the serious housing shortage arising from rapid urbanization and industrialization, residential communities were constructed to meet the growing demand for housing. However, mass construction of these residential communities unavoidably resulted in uniformity standardization. In particular, for high rise apartment blocs using the ground floor as the center of the lower levels housings has raised problem of sunshine, airing, privacy. The research which it sees as the house low evaluation it is coming to become it plans a public facilities on lower levels of the building which keeps the quality which the ground connection and human scale back separates as, to solve the problem point of the lower levels house and the resident collective life which is smooth becomes accomplished.

Nakseonjae in Changdeokgung Palace was established at The King Hunjong's 13rd year (1847), the mid-19th century. It was constructed for own rests of King Hunjong and the residence of Kyungbin (king's concubines), and is showing features of upper-class houses from several points such as rustic architectural types by getting out of authoritative aspects as king's shelter space within the palace, block and floor distribution that separated spaces for men and women, simplicity in structures and styles, and non-colorful painting etc. This study aims at tracing on which architectural types did the upper-class houses within Hanyang (modern Seoul) at late Joseon Dynasty have and what was characteristics of Nakseonjae. The resemblance between Nakseonjae and the upper-class houses was very little differences from scale aspects, and floor plan shapes of Anchae (women's quarters) and Sarangchae (men's quarters) were followed basic common styles. Also, resemblance could be confirmed in the structural styles too. Characteristics of Nakseonjae are showing apparent differences from clearance compositions such as hall configuration etc. Nakseonjae was king's dwelling place, and spaces for house's collateral functions such as kitchen, stable, and warehouse etc together with shrine were unnecessary, and such places were substituted into servants' quarters for assisting the Royal family. In detailed structural styles, column's size was larger 3cm or more than the upper-class houses, and its height was higher to the degree of 30~60cm. Besides, formality as king's shelter space was raised more in decorating aspects, and Nakseonjae was implemented by getting architectural influences from Qing Dynasty of China. This study induced features of Hanyang's upper-class houses at the 19th century by supplementing distribution and space configurations at existing cases of Seoul and Gyeonggi area together with house diagrams having been collected by Gaokdohyung (site and floor plan) of Jangseogak Library, and confirmed resemblances and differences with Nakseonjae, that is, features of Nakseonjae. Through the result, this study judges a fact that architecture of Nakseonjae seemed to be affected from conveniences of upper-class houses within Hanseong, and also architectural styles and distribution types of Nakseonje would give influences to the upper-class houses.

A total of 152 pig farms were randomly selected from the five provinces in South Korea. During the experiment, the average temperature and relative humidity was $24.7^{\circ}C$ and 74% in summer and $2.4^{\circ}C$ and 53% in winter, respectively. The correlation between floor space allowance (FSA) and productivity index was analyzed, including non-productive sow days (NPD), number of weaners (NOW), survival rate (SR), appearance rate of A-grade pork (ARA), and days at a slaughter weight of 110 kg (d-SW) at different growth stages. The objectives of the present study were i) to determine the effect of FSA on the pig productivity index and ii) to suggest the minimum FSA for pigs based on scientific baseline data. For the pregnant sow, NPD could be decreased if pregnant sows were raised with a medium level (M) of FSA (3.10 to $3.67m^2/head$) while also keeping the pig house clean which improves hygiene, and operating the ventilation system properly. For the farrowing sows, the NOW tended to decrease as the FSA increased. Similarly, a high level of FSA (H) is significantly negative with weaner SR of farrowing sows (p-value = 0.017), indicating this FSA tends to depress SR. Therefore, a FSA of 2.30 to $6.40m^2/head$ (very low) could be appropriate for weaners because a limited space can provide a sense of security and protection from external interruptions. The opposite trend was observed that an increase in floor space (> $1.12m^2/head$ leads to increase the SR of growing pigs. For the fattening pigs, H level of FSA was negatively correlated with SR, but M level of FSA was positively correlated with SR, indicating that SR tended to increase with the FSA of 1.10 to $1.27m^2/head$. In contrast, ARA of male fattening pigs showed opposite results. H level of FSA (1.27 to $1.47m^2/head$) was suggested to increase productivity because ARA was most affected by H level of space allowance with positive correlation ($R^2=0.523$). The relationship between the FSA and d-SW of fattening pigs was hard to identify because of the low $R^2$ value. However, the farms that provided a relatively large floor space (1.27 to $1.54m^2/head$) during the winter period showed d-SW was significantly and negatively affected by FSA.

The advent of an aging society has raised the necessity for housing development to meet the growing demands of baby boomers expected to act as the main consumers in the future housing market. This study aims to identify the characteristics of apartment houses favored by baby boomers in their post-retirement plans. Based on a literature review and survey, the study is targeted at a certain baby boom generation residing in mid- sized and large-sized apartments with a floor space of more than 30 pyeong in Gangnam, Seoul. The study reveals that baby boomers favor an active post-retirement life where they can enjoy proper leisure without considerable change in daily routines, and for that reason they choose an apartment house well equipped with neighboring, convenient facilities for their post-retirement. Their housing size shows a downward tendency in response to changes in economic conditions and number of family members living together. Health-related factors such as a comfortable natural environment and greenery also play a key role in their residence selection. Their regional preference is divided into the downtown and suburbs, and thus it will be necessary to satisfy the needs of these two consumer groups in the future housing market. This study lays the foundation for offering basic materials for the development and marketing of apartment houses.

A study was conducted to evaluate effects of alfalfa meal on growth performance and gastrointestinal tract development of growing layer ducks to provide evidence for application of alfalfa meal in the duck industry. Two hundred and fifty-six healthy Shaoxing 7-wk old growing layer ducks were selected and randomly allocated to 1 of 4 dietary treatments based on corn and soybean meal and containing 0, 3, 6, and 9% of alfalfa meal for 8 wks. Each treatment consisted of 4 replicates of 16 ducks each. Briefly, birds were raised in separate compartments, and each compartment consisted of three parts: indoor floor house, adjacent open area and a connecting water area. The results showed: i) Growing ducks fed alfalfa meal diet were not significantly different in average daily gain, feed intake and gain-to-feed ratio from those fed no alfalfa diet (p>0.05). ii) Alfalfa meal increased the ratio crop, gizzard to live weight, caecum to live weight, the caecum index of growing ducks (p<0.05). iii) Villus height in duodenum and jejunum of growing ducks increased significantly with the increase of alfalfa meal levels (p<0.05). Crypt depth in duodenum and jejunum of growing ducks decreased significantly with the increase of alfalfa meal levels (p<0.05). This experiment showed that feeding of alfalfa meal to growing layer ducks could improve gastrointestinal tract growth and small intestinal morphology without effect on performance. This experiment provides evidence that alfalfa meal is a very valuable feedstuff for growing layer ducks.
