The purpose of this study was to identify food management behavior of housewives in island areas and to find if the behavior patterns were different between the regions, Hansan and Ullung island. An instalment based on previous researches was designed to measure food management behavior and was administered to 274 housewives in 1994 and 1998. Considering the condition of cooking-equipment possession, the percentage of possession for refrigerator, mix, electric range were significantly higher for households in Hansan Island than their counterparts. For food-budget planning, those in Ullung Island were more likly to plan their budget than those in Hansan Island. Menu planning patterns, considerable factors for food selection as well as cooking, and eating habits between meals were tuned out to be different between Hansan and Ullung areas. The findings of this study suggest that the condition of cooking-equipment possession, food-budget and menu planning, considerable factors for food selection and cooking, eating habits between meals were likely to vary depending on regions. Although housewives in two areas were living in island, they were not necessarily be uniform for all households but were diversified in food management behavior. Half of the respondents in Hansan Island and three-forth of the respondents in Ullung Island reported they had not planned their meal budget. The percentage of those who did not have their planned menu was 52.7∼54.1% in Hansan Island and 37.1∼38.5% in Ullung Island. When purchasing food material, housewives in Hansan Island consider the seasoning food as the most important factor, whereas those in Ullung Island consider family preference as the most important factor

Encrypted images obtained through double random phase-encoding (DRPE) occupy considerable storage space. We propose efficient compression schemes to reduce the size of the encrypted data. In the proposed schemes, two state-of-art compression methods of JPEG and JP2K are applied to the quantized encrypted phase images obtained by combining the DRPE algorithm with the virtual photon counting imaging technique. We compute the nonlinear cross-correlation between the registered reference images and the compressed input images to verify the performance of the compression of double random phase-encoded images. We show quantitatively through experiments that considerable compression of the encrypted image data can be achieved while security and authentication factors are completely preserved.

Pre-eclampsia is known to cause considerable maternal morbidity and mortality. Thus, many studies have examined the etiopathogenesis of pre-eclampsia. While many pathophysiological factors related to pre-eclampsia have been identified, the precise etiopathogenesis of pre-eclampsia remains unclear. Numerous studies have identified factors for the early prediction for pre-eclampsia to lead to preparation and closer observation on pre-eclampsia when it occurs. This article reviews on current studies of biomarkers and genetic factors related to pre-eclampsia, which may be important for developing strategies for early prediction of pre-eclampsia.

Nowadays, with the constant enhancement in the health of the economy, the average income and living standard have accordingly increased, making the need for financial independence a favorable choice. This research aims to identify the factors affecting the financial independence of young people. The authors implement quantitative analysis, with a set of primary data collected from a survey of 2664 Vietnamese people aged from 18 to 28. The research results demonstrate the considerable impact of monetary, psychological, group-related, and family-related factors on the financial independence of young people. The results of the sample analysis provide adequate evidence to reject the correlative relationship between family and group factors and the financial independence of young people. In addition, there are 3 factors, including demographic factors, monetary factors, and psychological factors, all have varying degrees and directions of influence on young people's financial independence. Most of the mentioned variables reflect a positive effect on financial independence. The only exception is the education variable, illustrated by its negative standardized beta value. A significant difference in financial independence between genders also is reported, suggesting that males seem to have a higher level of financial independence than females.

Although there has been a considerable research in psychoneuroendocrinology, particularly in relation to the biology of mood disorders, there has been a paucity of research regarding the effects of psychological factors on endocrine diseases. Of the existing literature, the most research is focused on diabetes mellitus, graves' disease. Especially diabetes appears to be the only endocrine disease that has been the focus of recent research studies. Most of the studies had retrospective designs or several methodological flaw. There has been no consistent results demonstrating that psychological factors affect the onset of diabetes mellitus. Several studies have suggested that psychological factors affect the course of diabetes. A small number of studies showed some evidence that psychological stress was associated with changes in glucose regulation in a subset of diabetic patients. There was also evidence to suggest that some temperament and coping skill influence glycemic control in child, adolescent diabetics. Studies of behavioral or psychosocial intervention on diabetic control have been small and have produced mixed results. There was a few controlled study suggested that stressful life events might be a causal role in Cushing's disease and Graves'disease, but there is no presently sufficient evidence to suggest that psychological factors affect the onset and the course of Cushing's disease and Graves' disease. In future, there is need for a well-designed biopsychosocial research with prospective designs, well defined patient population and control groups to study the relationship between psychological factors and endocrine diseases.

The slab analogy method was introduced in the 1920's for the first time as a new experimental stress analysis method. Notwithstanding its theoretical propriety, this method has not been recognized as efficient one because of its difficulty in practical measurement of the slab curvature. In this paper, aiming at experimental determination of two-dimensional stress intensity factors(S. I. F) of arbitrarily shaped cracks which had been regarded as almost impossible by conventional method, the slab analogy was reevaluated. Measuring of slab curvature was replaced by three simple measuring factors to overcome vital slab-analogy's shortcoming by joint use of the shadow-moire method. A determination formula was also derived from the theory of fracture mechanics. By this newly exploited method, it was found that the slab analogy still has its great advantage in determination of S.I.F. of arbitrarily shaped cracks with considerable accuracy compared with existent experimental methods.

Design live load and girder distribution factors play an important role in the current design procedures. The fraction of vehicle load effect transferred to a single member may be selected in accordance with current KBDC. However, the specified values, both design load and distribution factors involve considerable inaccuracies, These inaccuracies relate to the uncertainties of the structural analysis, especially any bias and scatter which drives from the use of simplified load distribution factors. In this study , based on several field measurement and finite element analysis, live load distribution effects of current KBDC are evaluated. The final values of the bias and coefficient of variation of "g"according to bridge type are determined. The bridge types are reinforced concrete slab, prestressed concrete girder and steel l-beam.el l-beam.

Effects of temperature dependent material properties on mixed mode fracture parameters of functionally graded materials subjected to thermal loading are investigated. A domain form of the $J_k$-integral method including temperature-dependent material properties and its numerical implementation using finite element analysis is presented. Temperature and displacement fields are calculated using finite element analysis and are used to compute mixed mode stress intensity factors using the $J_k$-integral. Numerical results indicate that temperature-dependency of material properties has considerable effect on the mixed-mode stress intensity factors of cracked functionally graded structures.

The structure and dimensionality of the User Information Satisfaction (UIS) construct is an important theoretical issue that received considerable attentions. The acceptance of UIS as a standardized instrument requires confirmation that it explains and measures the user information satisfaction construct and its component. Based on a simple of 670 respondents who participated in dealing with the Public Management Information System (PMIS), this research used a confirmatory factor analysis to test the alternavtive models of underlying factor structure and assessed the reliability and validity of these factors and items in the PMIS. The result provided a support for a revised UIS model with four first-order factors and one PMIS The result provided a support for a revised UIS model with four first-order factors and one second-order (higher-order) factor in PMIS. To cross-validata these results, the author reexamined two prior data sets. The results showed that the revised model provides better model-data fit in all three data sets.
