The purposes of this study were to understand the sex role identity and the meaning in life(MIL) of matriarchs and analyze their relationships to offer basic data for effective nursing strategies for improving MIL. The data for this study was collected from the 10th of August to the 30th of November, 2000. The subjects were women registered in an occupational training program for unemployed matriarchs which is held in the Working Women's Center in Busan. The measurement tools of this study were MIL(unpublished)developed by researchers and sex role inventory designed by Kim Deuk Ran(1992). The results of this study were as follows: 1.Sex role identities of matriarchs were feminity 13.7%, masculinity 13.4%, androgyny 37.8% and undifferentiated 35.1%. 2. The mean MIL for matriarchs was $173.46{\pm}16.09$. 3. The levels of MIL were 57.2% of the subjects felt a loss of meaning in life, i. e. existential vacuum, 42.8% were in pursuit of meaning but had not discovered it completely and 6.0% felt they had established meaning in life. 4.There were significant differences in MIL levels, concurrent to 4 types of sex role identities(F=11.93, P=.000). And according to Scheffe's post test, between feminity and masculinity, feminity and androgyny, masculinity and the undifferentiated, androgyny and the undifferentiated, there were significant differences. From the results of this study, most matriarchs felt loss of meaning in life, i. e. existential vacuum, and the group with masculine sex role identity had the highest level of MIL. In conclusion, the factors related to masculine sex role identity are necessary to develop nursing strategies for improving levels of MIL.

Pets are increasingly becoming vital companions in human life, prompting researchers to focus on understanding the grief experiences of pet owners. Unlike other forms of loss, pet loss often leads to complicated grief, characterized by intense and prolonged sorrow. This is likely due to the comparatively lower societal value placed on the human-pet relationship, which may restrict pet owners from feeling truly understood by others. The subjective perception of these "social constraints" significantly hampers the process of recovering from pet loss and contributes to the development of complicated grief. In this study, we hypothesize that the perceived social constraints could intensify the transition from the initial shock of pet loss to complicated grief. The results confirm that pet owners' perceived social constraints play a moderating role in the relationship between the shock of pet loss and complicated grief. Notably, pet owners experience heightened levels of complicated grief when perceiving greater social barriers and constraints. By highlighting the pivotal role of perceived social constraints in comprehending the experiences of pet loss and grief, this study underscores the importance of social awareness and improvement.

A numerical calculation is carried out for the analysis of 3-dimensional compressible flow field in axial-flow rotating blades by using finite element method. The calculation of flow in impellers plays a dominant role in the theoretical research and design of turbomachines. Three-dimensional flow fields can be obtained by the quasi-three-dimensional iterative calculation of the flows both on blade-to-blade stream surfaces and hub-to-shroud stream surfaces with the introduction of viscous loss model in order to consider a loss due to viscosity of fluid. In devising the loss model, four primary sources of losses were identified: (1) blade profile loss (2) end wall loss (3) secondary flow loss (4) tip-leakage loss. For the consideration of an axially parabolic distribution of loss, the results of present calcullation are well agreed with the results by experiment, thus the introduction of loss model is proved to be valid.

The skin is a barrier between the living organism and its environment, and this barrier function resides in the stratum corneum. The main function of the stratum corneum is to serve as a barrier preventing the penetration of irritants and transepidermal water loss(TEWL). The rate of transepidermal water loss is a convenient parameter for expressing barrier function. Impaired barrier function was manifested by a greatly increased rate of transepidermal water loss. In atopic dermatitis the rate of transepidermal water lossis greatly increased transepidermal water loss. Medication of Gagampalmultang restored to normal the abnormally high rates of transepidermal water loss in the 104 patients with atopic dermatitis. It specifically plays an important role in regulating barrier function.

Since 1998 when economic assistance from IMF started, the empirical research on the effects of unemployment and drastic income loss on psychological functioning among the unemployed as well as their family members has increased. These studies have found that unemployment and drastic income loss following unemployment have significant negative influence on the psychological outcomes such as anxiety and depression of the unemployed and their family members. Studies have also focused on the role of social support in this process, and reported that depending on the levels of received social support, unemployment and income loss have differential effects on the psychological aspects of the unemployed. However, these studies have several weaknesses. First, most of the related studies employed the data which were collected from limited regions of the country, which imposes limitations on the scope of the generalizability of research findings. Second, the main independent variables used in these studies were mainly unemployment or income loss, which ignore the psychological evaluation by the employed of their family financial situations. Third, in analyzing the moderating effects of social support, most studies have focused mainly on showing the existence of moderating effects by social support. Consequently, the nature and role of social support remained unanalyzed and left to speculations. The purpose, of this study is to examine the effects of economic pressure experienced by family heads who were unemployed and to analyze the moderating role of social support based on a nationally representative sample. The findings showed that economic pressure has negative influence on anxiety and depressive feelings among the unemployed, and that the effect of economic pressure on depressive feelings were substantially higher among those who have received lower levels of social support from family members than that among those with higher levels of family support.

This paper deals experimently with the difference between the cabins in ship-board and the reverberation chamber in sound transmission loss. Experimental results from the cabins show that there are various flanking transmission losses which deteriorate significantly the performance of the sound transmission loss. They also show that as a representative of the flanking transmission losses, sound leakages between a ceiling and a wall, the joints of the partitions, and the luminant devices play an important role. From the various measurements, it can be is concluded that unless one do not take any treatments on the flanking transmission loss, the field sound transmission loss will be considerably decreased by more than 10 dB, comparable to the sound transmission loss.

The present study empirically confirmed Korean elder's four major pains consisted of poverty, disease, role loss, loneliness and investigated the mediating role of depression between the four major pains and the elder's suicidal thought. To investigate the cause and effect of factors, we conveniently collected 309 samples from 16 Gyungrodangs evenly located in Jeonju and 291 samples, survived the data cleaning such as missing values, outliers, normality and covariance conditions, were analyzed by frequency, factor analysis, reliability, confirmatory factor analysis and structural model analysis. Followed were the selected contributions of the present study. First, the constructs of four major pains such as poverty, disease, role loss, loneliness were predictors of suicidal thought mediated by depression. Second, the elder's poverty, that was the heaviest factor of the four major pain constructs, was a predictor of role loss leading to loneliness. Third, four major pains were predictors of the elder's depression. Note that poverty were not direct but indirect predictor of depression. The present study confirmed the concept of four major pains. Also those who practice in the area of the elderly care should consider the four major pains as well as depression while intervening in the elderly's suicidal thought.

Thin-gauged 3% silicon steel sheets having a highly grain-oriented texture have been developed as a core material for applications of middle-frequency (400 Hz ${\sim}$ 10 kHz) devices. The newly developed sheets with a tension coating showed an excellent reduction in iron loss at 400 Hz (iron loss at 1.0 T and 400 Hz = 4.677 W/kg, iron loss at 1.5 T and 400 Hz = 9.742 W/kg) due to high magnetic induction, $B_{10}$(measured induction at 1000 A/m), of over 1.9 T. In cases of frequencies below 400 Hz, magnetic induction, $B_{10}$, of the sample plays a major role to reduce its iron loss as excitation induction increases, whereas, in case of frequency of 1 kHz, thickness dependence becomes dominant due to a lower iron loss at relatively thinner sample. The sheets with a high magnetic induction, therefore, are favorable for high excitation induction (over 1.0 T) and low excitation frequency (below 400 Hz) applications, whereas the sheets that can reduce eddy current loss by reducing thickness or domain wall width are advantageous for low excitation induction (below 1.0 T) and high excitation frequency (around 1 kHz) applications.

The role of empirical equation to predict the performance of polymer electrolyte membrane fuel cell is important. The activation, ohmic and mass transfer losses were separated in a polarization curve, and the curve fitting according to each region was performed using Kim's model and Hao's model. Changes of each loss were compared according to operation variables of the temperature, pressure, oxygen concentration and membrane thickness. The existing model showed a good fitting convergence, but less fitting accuracy in the separated loss region. A new model using the convergence coefficient was suggested to improve the accuracy of performance prediction of fuel cells of which results were demonstrated.
