The purpose of this study is to present basic data of clarifying the differences between employed and unemployed wives' family and comparing low classes with other classes for the more reasonable and successful home administration through investigating and analyzing decision-making patterns of the families of working women in the low income group. The questionnaires were distributed in September 1984 to 300 working women in the city of Seoul and Sung-Nam. Statistical methods such as frequency, percentage and the mean value were used for grasping general characteristics of the families and F-test, Pearson's Correlations were used for investigating the interrelation of the related variables. The results of this study were as follows; 1) Wife's participation indecision-making was increased while joint decision-making was decreased compared with those of unemployed wives' family and other classes. 2) Both of the degree of conjugal participation in decision-making and joint decision-making were influenced by wife's educational level, disparity in educations of couple, husbands' occupation, family income, wife's age. But duration of marriage affected only the degree of joint decision-making. Especially family income and husbands; occupations turned to be important variables in low income families. 3) In case of wife's satisfaction with her occupation, joint decision-making was well achieved or not according to certain decision items. Though wife and husband satisfied with their marriage, joint decision-making was not well performed in working wives' family with low income.

In this study, it was started with the research for improving the housing plan of the elderly and the aged housing environment. The spatial extent of the study is in Haedoji Village, Yeongdo, Busan, and the time ranged from the mid-1950s, when the Korean war broke out and the refugees started to settle, to the present as of August 2017. As Result, the size of the residential space per capita was overcrowded at $9.2m^2$ in the 1970s and 1980s, when the number of families was high, but since 2010, the size of the residential space currently living alone with only one elderly or couple was $29.2m^2$. In the future, it can be judged that the size of elderly housing can be expected to be envisioned within about $35{\sim}40m^2$ in consideration of the diversity of housing including table space in the 2LDK type.

In this study, a generic airfoil designed by the inverse method was evaluated with several candidate airfoils as a first step. Each airfoil was compared with respect to aerodynamic performance to meet the requirement of HALE(high altitude long endurance) aircraft. The second step was to optimize the candidate airfoil using the couple of optimization formulations to down select an optimum airfoil. For the analysis of low Reynolds number 2D flow, Drela's MSES was used. After comparing the aerodynamic results, the best airfoil was chosen to construct the baseline 3D wing. The Navier-Stokes code was used to evaluate the overall aerodynamic performance of designed wing with other wings. The results show that the designed wing has the best performance compared with other wings.

The Study of Hansun(Traditional Fishing Boat of Korea) is based on Fishing Bost Investigation Report which began in 1921. The Report was completed in 1927 with the conclusion of Southern sea Region and Western sea Region studies which included the investigation of the entire region. Based on this report, this paper surveys Hansun's characteristics style of boat and performance. The First couple of chapters are possibility of combining type of Hansun and modern Sailing Boat. As a result we find out that the hull form of Hansun is very similar with that of modern sailing boats and is a good candidate for the mother ship to develop the modern sailing boats for Korean sea.

This study aims to identify the usage behavior of An-bang space in apartment dwellers through the perception, the residential life style and the use of furniture. The data is collected from interviewing housewives through questionnaire designed for this study. The 210 date were analyzed by using Frequencies, Mean, Factor analysis, ${\chi}^2-test$, t-test, one-way ANOVA and scheffe-test. The main results of the study are as follows: (1) It is called An-bang' or 'large room' rather than 'master's bedroom' although it is recognized as exclusively couple-oriented space. And are founded to be different designation and perception on An-bang space. (2) The residential life style in An-bang is classified as family-centered gathered, rest entertainment, make-up fitting and hobby. And it has significant differences among dwellers according to their personal characteristics. (3) The furniture style and arrangement pattern are mostly modern ones and 'ㄷ' type.

The purpose of this study was to evaluate the relationship between marital quality and parent-fetal attachment. The sample included 395 pregnant women and 251 spouses who participated in Pregnant Education Programs. We analyzed the data which were collected by means of a questionnaire from September to November, 2011. The results were summarized as follows: The total marital quality level of pregnant couples was above the average and parent- fetal attachment levels were very high. Result indicated a difference in pregnant women and spouses regarding marital quality and parent-fetal attachment. The pregnant woman's marital quality and parent characteristics (planned pregnant, pregnancy period, birth order) had a significant correlation with parent-fetal attachment. The higher effective communication and conflict resolution regarding marital quality were, the higher parent-fetal attachment was.

This paper deals with the estimation of limiting distribution parameters, which have a close relation with product reliability characteristics in reliability test. Among the many kinds of estimation methods, probability paper is commonly used. The limiting probability paper is very convenient, but it has a great disadvantage in estimation accuracy by plotting method. It is very difficult to get the same results even if one use the same data several times. A computer program for the regression method is used for the parameter estimation to reduce these errors. Especially, the computer graphic program was written in GW-BASIC 3.22 language and a couple of running examples for user's reference appears in the appendix part.

After the collapse of the Tacoma bay bridge at Tacoma Washington, the accurate prediction of aerodynamics became crucial to the sound design of bridges. CFD(Computational Fluid Dynamics) becomes important tool for the prediction on wind effects on the bridge due to the recent development of CFD. The usage of CFD is further prompted by the advantages in using CFD, such as low-cost and fast feed-back of design. In this paper, an unsteady compressible Reynolds averaged Navier-Stokes code is used for the computation of the flow over bridges. Coakley's ��q-${\omega}$ �� two-equation turbulence model is used for the turbulent eddy viscosity. For accurate and stable computations, the local preconditioning method is adapted to the code. Aerodynamic characteristics of a couple bridges are presented to show the validity and the accuracy of the method.

This study is purposed to analyse the relationship among the demographic characteristics of rural families and their household work time use and the perception of their quality of life. This study also intended to show the difference of the housold work time use between the rural and the urban area. The household work time use behavior of the urban families were analized in former study by this author, and the results were used in this study for comparison. 200 rural families were sampled which are composed of a couple with two children. These families were then stratified by wife's employment status and age of children. For the statistical analysis of the data, ANOVA, GLM, X\sup 2\-test and etc. were employed.

This paper studies the estimation of hazard parameters, which have a close relation with product reliability characteristics in reliability test. Among the many kinds of estimation methods, hazard Probability Paper(HPP) is commonly used. The HPP is very convenient, but it has a great disadvantage in estimation W by plotting method It is very difficult to get the same results even if one use the same data several times. A computer program for the regression method is used for the parameter estimation to reduce these errors. Especially, the computer graphic program was written in GW-BASIC 3.22 language and a couple of running examples for user's reference appears in the appendix part.
