This study investigates the impact of the shared environment of pregnant women and their unborn child on the later emotional and behavioral characteristics of a child, extending into his or her adulthood. Using a sample of some 16,000 children from the National Child Development Study, the study demonstrated a positive relationship between the quality of the maternal environment and later emotional and behavioral performances during childhood and adulthood. These findings support the study hypothesis, suggesting that parenting environment such as mother‘s employment, husband’s social class and the mother‘s smoking habits during pregnancy has an affection on the later emotional and behavioral development of the child. The dimensions of the child’s emotional and behavioral well-being may be enhanced by therapeutic interventions and/or by helping pregnant women to develop a positive social network.

We studied the meaning of the term avant-garde in relation to clothing of the 1980s and 1990s by examining the media's perceptions of Martin Margiela, a Belgian deconstructionist designer who was often labeled as avant-garde by journalists, scholars, and fashion critics in the late 20th century. A five-step content analysis method described by Paoletti (1982) was used to conduct the research. Newspaper and magazine articles in the 1980s and 1990s were analyzed using a set of existing avant-garde characteristics developed by Crane (1987) to determine if those journalists' perceptions matched the characteristics described by Crane. Results indicated that the journalists' critiques and descriptions matched the avant-garde characteristics described by Crane (1987). Including a subjective element to the conceptualization of the term explains how journalists described Margiela's designs despite Japanese designers' use of similar techniques before him. We (re) conceptualize the term's latter 20th century meaning and shifting dialogue to include a subjective element.

The thermomechanical behaviors of the shape memory alloy were conducted through the finite element analysis of ABAQUS with UMAT user subroutine. The unified thermomechanical constitutive equation suggested by Lagoudas was adapted into the UMAT user subroutine to investigate the characteristics of the shape memory alloy. The three cases were solved to investigate the thermomechanical characteristics of the shape memory alloy. The material properties for the analysis were obtained by DSC and DMA techniques. According to the results, the thermomechanical characteristics, such as a shape memory effect and a pseudoelastic effect, could be obtained through the finite element analysis and the analysis results were revealed to agree well with the experimental results. Therefore, the finite element analysis using UMAT user subroutine is one of prominent analysis techniques to investigate the thermomechnical behaviors of the shape memory alloy quantitatively.

As the environmental regulations become stricter, new machining technologies are being developed which takes envi ronmenta 1 aspects into account . Since cut t ing oi I has some impact on environment. many researches are being carried out to minimize the use of cutting oi I. The methods for minimizing cutting oil usage includes the following techniques: I ) Cooling of tools and work piece. 2) Useage of compressed cooling air for the removal of chip. 3) Minimal useage of environment-friendly vegetable cutt:ngoiI for lubrication between chip and tools. Since the turning machine is continuous, tools are under constant thermal load and tool wear increases as the lubricative performance degrades. Also surface roughnesses have a direct influence on turning. In order to examine the characteristics of turningmachining, this work investigates experimentally the degree of tool wear and characteristics of surface roughness in relation to machining conditions, supply methods, and cooling methods.

Recently the change of family environment has influence on the configuration of the family welfare unit at the social welfare center. And so the relation of space and function required its change. The essential role of social welfare center is family welfare, domiciliary and community care, community organization, social education etc. In this sence, this study explored the condition of space planning for the family welfare at the social welfare center. For this study, it was reviewed the role and function, the service program, the degree of unit activity importance, space satisfaction, the usage characteristics. In sum, the useful data were collected, analyzed, and synthesized through case study and could be used in the guidelines as reference information for the spatial organization of the family welfare unit at the social welfare centers in small town.

Geotextile containers for restoration of slopes form the interface between the containers during the restored to lost slopes, and therefore the relation displacements are developed including the sliding on the surface. Since, the shear strength on these interfaces is less than that of fill material in the container, the characteristics of shear strength on the interface governs the behavior of the restoration slopes. In general, a lot of natural properties of geotexiles is required to evaluate the safty of the geotextiles, Among the properties, the shear characteristics between geotextiles and soil is a important variable to assess the safety. From the results of full scale direct shear test, the residual shear strength is recommanded to use for design factors since a large deformation possibly occures on the geotextile containers.

The purpose of this study was to investigate the relation between health behavior patterns and demographic, socio-economic characteristics, health status, health information in Korea. The quantification method through canonical correlation analysis was conducted to the data from Korea National Health Survey in 1995, which consisted of 5,805 persons. The health lifestyle patterns were quantified as good diet lifestyle, passive lifestyle to the negative direction and drinker lifestyle, smoker lifestyle, hedonic lifestyle and fitness lifestyle to the positive direction. The covariate were related to health lifestyle patterns in the order of sex, age, marital status, occupation, health information, economic status, level of physical labour and health status. Characteristics of male, age below 50, married, blue colored worker, no health information, low in economic status, heavy level of physical labour, and poor in health status were positively related to drinker lifestyle, smoker lifestyle, hedonic lifestyle, fitness lifestyle sequentially.

A numerical investigation using a commercial CFD program of the Inter-Phase Slip Algorithm has been carried out for detail characteristics of particle motions and bubble behaviors in a two dimensional fluidized bed. The bed simulated has been operated with three different distributor geometries, such as bubble cap, nozzle, and perforated plate types. Experiments using a slit-type two-dimensional fluidized bed and a cylinder-type fluidized bed have been performed in order to confirm the simulation model. In addition, the numerical results are compared with the wellknown correlation of bubble sizes and bubble rising velocities by Mori and Wen [1]. The simulation model that we applied is shown to be useful to understand the relation between bubble behaviors and distributor geometries.

Failure occurred slope, due to typhoon 'Rusa' and 'Maemi' last two years, was studied to evaluate the slope failure characteristics. There're three types of the slope in this study, ie. soil slope, rock slope, mixed slope. Statistical analysis was used to estimate the relation between slope type and failure mode. Among the failure occurred slope, soil slope & mixed slope are dominant at the ratio of 33%, 44% respectively. We conclude that soil slope & mixed slope have more higher risk than rock slope during heavy rainfall.

Effects of the evaporation rate of MgO films using electron beam were investigated on the MgO properties and the discharge characteristics of the plasma display panel (PDP). The evaporation rate was changed from 3 ${\AA}/sec$ to 15 ${\AA}/sec$ at a substrate temperature of $300\;^{\circ}C$. MgO properties such as crystal orientation, surface roughness, contact angle, and film structure were inspected using XPS, AFM, drop shape analysis and SEM. We also studied the relation between MgO properties and PDP discharging characteristics. The minimum firing voltage and maximum efficacy were obtained at evaporation rate of 5 ${\AA}/sec$. In the MgO film deposited at 5 ${\AA}/sec$, (200) orientation was most intensive and surface roughness was minimum.
