This study examined the double mediating effects of work-family conflict and parenting guilt on the relationship between perfectionism and parenting behavior for working mothers. The survey was conducted on 340 working mothers with 3 to 5 year-old children, who lived in Daegu and Kyungpook Province, Korea. Data were collected through questionnaires on perfectionism, work-family conflict, parenting guilt, and parenting behavior. To analyze the collected data, descriptive statistics, factor analysis, and analysis of variance were conducted by using SPSS 22.0 and Model 6 in PROCESS macro, with bootstrapping method. Work-family conflict and parenting guilt were used as mediators. Children's birth order and household income were controlled throughout the analysis. The major findings of this study were as follows. First, work-family conflict and parenting guilt had inconsistent double mediating effects on the relationship between adaptive perfectionism and positive parenting behavior. Second, work-family conflict and parenting guilt had complete double mediating effects on the relationship between adaptive perfectionism and negative parenting behavior. Third, work-family conflict and parenting guilt did not have double mediating effects on the relationship between maladaptive perfectionism and positive parenting behavior. Finally, work-family conflict and parenting guilt had partial double mediating effects on the relationship between maladaptive perfectionism and negative parenting behavior. The findings provide a better understanding of the relationship between perfectionism and parenting behavior. The results also have implications for providing education for and counseling working mothers with children.

This paper proposes a confronting feedback control structure and controllers for positive output elementary super lift Luo converters (POESLLCs) working in discontinuous conduction mode (DCM). The POESLLC offers the merits like high voltage transfer gain, good efficiency, and minimized coil current and capacitor voltage ripples. The POESLLC working in DCM holds the value of not having right half pole zero (RHPZ) in their control to output transfer function unlike continuous conduction mode (CCM). Also the DCM bestows superlative dynamic response, eliminates the reverse recovery troubles of diode and retains the stability. The proposed control structure involves two controllers respectively to control the voltage (outer) loop and the current (inner) loop to confront the time-varying ON/OFF characteristics of variable structured systems (VSSs) like POESLLC. This study involves two different combination of feedback controllers viz. the proportional integral controller (PIC) plus sliding mode controller (SMC) and the fuzzy logic controller (FLC) plus SMC. The state space averaging modeling of POESLLC in DCM is reviewed first, then design of PIC, FLC and SMC are detailed. The performance of developed controller combinations is studied at different working states of the POESLLC system by MATLAB-Simulink implementation. Further the experimental corroboration is done through implementation of the developed controllers in PIC 16F877A processor. The prototype uses IRF250 MOSFET, IR2110 driver and UF5408 diodes. The results reassured the proficiency of designed FLC plus SMC combination over its counterpart PIC plus SMC.

Hospitals accomodate patients who have a high risk of infection due to reduced immunity as well as people who require surgical, medical or other treatments. Consequently, the role of clinical nurses, who come into close contact with these patients is very important in the control of nosocomial infection. This study was done to investigate and compare the level of perception of the importance of the control of nosocomial infections as well as the level of actual performance, and the level of satisfaction with the control of nosocomial infection by the clinical nurses. Thus, the purpose of this study is to contribute basic data for improving policies and educational programs to control nosocomial infection. A summary of the survey results is as follows. 1) The means of scores on all categories of the inquiry were 4. 51 for awareness 4.42 for actual performance, and 3.20 for satisfaction, of a possible high score of 5.00. 2) Correlations of the level of perception of importance between characteristics of nurses and hospital control of nosocomial infection differed significantly according to the type of hospital establishment type (p=.005), age(p=.000), career(p=.000), position (p=.002), and regular conferences on infection control in working departments(p=.003), Correlation of the level of actual performance between characteristics of nurses and hospital control of nosocomial infection diffesed significantly according to type of hospital(p=.000), hospital size (p=.009), working department(p=.000), age(p=.000), career (p=.000), school career(p=.040), position (p=.000), education experience on nosocomial infection(p=.020), and regular conferences on infection control in working department(p=.000). Correlation of degree of satisfaction between characteristics of nurses and hospital control of nosocomial infection also differed significantly according to the type of hospital establishment (p=.003), working department(p=.000), age (p=.000), and regular conferences on infection control in working department (p=.000). 3) Correlation between clinical nurses, level of perception of importance and actual level of performance for the control of nosocomial infection was relatively positive (r=.57, p=.000). Correlation between clinical nurses degree of satisfaction and level of actual performance for control of nosocomial infection was relatively positive (r=.47, p=.000).

The purpose of this study was to examine the effect of a householder's working type on household saving from the perspective of precautionary saving behavior theory and the determinants of household saving by householder's working type. The data for this study was from the 2009 year of the Korea Welfare Panel Survey (KOWEPS), consisting of 2,463 households with householders whose working type was regular or non-regular employment(temporary, daily or public work). OLS regression analyses and Chow-tests were performed. In the regression analyses, the dependent variables for household saving were precautionary saving and precautionary asset. Precautionary saving was operationalized with the amount of average monthly saving and the ratio of average monthly saving to average monthly disposable income, and precautionary asset was operationalized with the amount of financial assets and the ratio of financial assets to net assets. The independent variables were household income, household assets, householder's working type(regular, non-regular), householder's age, sex, education level and marriage status, income level, the number of household members, housing type, debt, and public transfer income. Monthly average total consumption expenditures for household income, and net assets for household assets, the existence of spouse for marriage status, poverty for income level were used. Public transfer income was classified into three, social insurance, basic assistance and government assistance. For the analyses, Stata 11.0 version was used. The results are as follows: Householder's working type was significantly related to the precautionary saving behavior of a household. However, the precautionary saving and the precautionary asset of a household with a householder in non-regular working type was lower than those of a household with a householder in regular working type. This result is not consistent with the expectation from the perspective of precautionary saving behavior that the saving of a household with a householder in non-regular working type is expected to be higher than that of a household with a householder in regular working type. According to the analyses of the determinants for precautionary saving behavior by householder's working type, monthly average total consumption expenditures, debt, net assets, poverty, the number of household members, basic assistance were statistically significant variables. The positive relation of basic assistance to precautionary saving(the amount of average monthly saving and the ratio of average monthly saving)is a noteworthy result in the analyses of the determinants for household saving by householder's working type. The above results suggest the followings. First, it is easy to predict the unstability of economic life of a household with a householder in non-regular working type because of relatively low precautionary saving and precautionary asset. The reason for the low precautionary saving and the low precautionary asset may be a low current income of the household in spite of its willingness to save. If this reasoning is possible, it suggests that policies are needed for households with householders in non-regular working type to save. Second, the relatively low precautionary saving and precautionary asset of a household with a householder in non-regular working type suggest also their long-term economic stability. This suggests they need to try a long-term financial planning even though they have limitations to save for future because of their low current income. It is necessary to develop the financial planning for the households with unstable incomes. Third, the determinants for precautionary saving behavior by householder's working type were mostly the ones which reflect the economic condition of a household. This suggests that the economic condition of a household is a core factor for household saving. Consequently, it emphasizes the efforts for a household to acquire the adequate level of income for saving. Forth, the positive relation of basic assistance to precautionary saving(the amount of average monthly saving and the ratio of average monthly saving) suggests the possibility for a household to accumulate the precautionary saving and the precautionary asset in the channel of basic assistance.

Objectives: This study aimed to investigate the effects of verbal violence experience on stress and positive psychological capital as well as the mediating effects of positive psychological capital. Methods: A survey was conducted with dental hygienists working at university hospitals, general hospitals, and dental hospitals and clinics in Busan, Gyeongnam, and Ulsan areas.Of the 230 questionnaires distributed, 206 were used in the analysis after excluding 24 completed questionnaires that had errors or missing answers. Results: As a result of identifying the relationships between verbal violence damage, positive psychological capital, and stress, verbal violence damage was negatively correlated with positive psychological capital (r=-0.28, p<0.001) and positively correlated with stress (r=0.40, p<0.001). Positive psychological capital had a negative correlation with stress (r=-0.25, p<0.001). As a result of verifying the mediating effects of positive psychological capital on the relationship between verbal violence damage and stress among dental hygienists, it was found that verbal violence had a significant effect on stress and positive psychological capital in the first and second stages. In the third stage, the effect of positive psychological capital on stress was significant, showing that there was a mediating effect. Conclusions: Therefore, sound work environments should aim to reduce verbal violence while increasing support systems to reduce negative emotional and psychological states.
