Early 20th century Singapore was faced with the problem of overcrowding. The attendant problems of a rapid increase in population density, namely the lack of proper housing and sanitation, resulted in the issue of an appropriate residential environment emerging as an important task in urban planning. It was necessary to construct housing estates in order to solve this issue. At that time, the British colonial government attempted to transplant modern technology into the construction process of a residential complex system. However, Singapore's climate and traditional lifestyle made it impossible to apply the British modern system in a straightforward manner, and in the process, a number of transformations emerged. With a specific focus on the Tiong Bahru estate, one of Singapore's representative public housing projects, from the 1930s through the 1950s, this study intends to look at the way in which such residential estates were assimilated into local surroundings, and the effect of the transplantation of British concepts of modern housing theory. Therefore, the study is divided into an examination of the estate both before and after the turning point of World War II. This study confirms that the difference between the pre-war and post-war planning strategies for the Tiong Bahru estate were made according to the concept of 'open space.'

In this study, the characteristics and patterns of family problems were explored. What constituted family problems, and how those evolved over the period of drastic changes in the Korean society were examined, by analyzing articles published from the 1940s to the 1980s in the four major national newspapers in Korea. A total of 6542 articles related to family problems in the four newspapers, Chosun, Dong-A, Kyunghyang, and Seoul, were used for the content analysis of this study. The main categories of family problems were classified as poverty, marital issues, issues related to children and adolescents, elderly issues, problems in the family as an institution, and the so-called family-lag problem. Each of these categories consisted of several subcategories: The poverty-related problems included the problems caused by difficulty in making a living and instability of living, for example. The marital issues category consisted of conflicts between the couple, unfaithful spouses, domestic violence, divorce, and so on. Issues related to children and adolescents included juvenile delinquency, difficulty in bringing up children, child abuse, single motherhood, and underage household heads, for example. The elderly issues included the anxiety over the aging society, support for the elderly, conflicts between mother-in-law and daughter-in-law, alienation of the elderly, etc. Problems in the family as an institution consisted of the legal issues in such areas as marriage, succession of the family head, and adoption. Lastly, the family-lag problem included confusion over family values, and conflict caused by the inconsistency between consciousness and actual behavior related to the family or family crisis. From the 1940s to the 1980s, family-lag was the most common problem (26.2% of the total articles), followed by issues related to children and adolescents (23.1%), poverty (16.2%), marital issues (15.9%), elderly issues (12.4%), and problems in the family as an institution (6.0%). During the 1940s and the 1950s, poverty was a prominent problem, and in the 1960s, issues related to children and adolescents were most commonly addressed in the articles. In the 1970s and the 1980s, the family-lag problem was the most frequently addressed.

This study was conducted to provide a guideline for laying hens breeding through comparing performance test results and domestic and foreign breeding processing for the purpose of succeeding in laying hen industry. The annual average egg numbers were 120 at 1930, 135 at 1940 and 175 at 1950 which was 146% increase during a decade. Heterosis was firstly introduced at 1924 and was applied to produce commercial stock since 1950. The theory of selection for quantitative traits was established by Lerner in 1951. In Europe and America, the annual average egg numbers in performance test were 175, 213, 219 and 277 in 1950, 1960, 1970 and 1985, respectively, and in Korea, those were 196, 226 and 265 in 1960, 1970 and 1980, respectively Laying hen breeding through simultaneous selection of numerous traits may provoke elevation of viability, improvement of feed efficiency, alongation of laying period and increase of disease resistance.

Using the CFD method, the pressure drop in 6 cyclone dust collectors of different shape were calculated. And the results were compared with results of the conventional theories. Equations of Shepherd and Lapple (1939, 1940), First (1950), Alexander (1949), Stairmand (1949), Barth (1956) were used in the theoretical calculation. In CFD calculations, we used standard k-epsilon model for analysis of turbulent flow, fluid is $25^{\circ}C$ air, the velocity at inlet is 10 m/s and the temperature is $25^{\circ}C$. In CFD analysis results, the pressure distributions along the flow showed similar patterns in different cyclone shapes. But the pressure drop distributions estimated on the conventional theories had big difference in different cyclone shapes. Only First's theory and CFD analysis showed similar results.
