Purpose : The lipid profile is a major predictive index for cardiovascular disease, but there have only been a few studies conducted on the relationship between lipid ratio and cardiovascular disease risk factors in the Korean population. To address this research gap, we investigated the association between three lipid ratios and cardiovascular disease risk factors among Korean adults. Methods : This study used data from the seventh Korea National Health and Nutrition Examination Survey conducted in 2016. Lipid ratios included triglyceride (TG)/high density lipoprotein cholesterol (HDL), total cholesterol (TC)/HDL, and low density lipoprotein cholesterol (LDL)/HDL. Cardiovascular risk factors included in this research were: systolic blood pressure $(SBP){\geq}140$, diastolic blood pressure $(DBP){\geq}90$, fasting blood sugar $(FBS){\geq}126$, $HbA1c{\geq}6.5$, body mass index $(BMI){\geq}25$, waist circumference (WC) $men{\geq}90$, $women{\geq}85$, and metabolic syndrome (MetS). A complex samples logistic regression test was performed to analyze the association between lipid ratios and cardiovascular disease risk factors. Results : 1) TG/HDL ratio had statistically significant relationships with DBP, FBS, HbA1c, BMI, WC and MetS. 2) TC/HDL ratio was correlated to SBP, DBP, FBS, BMI, WC, and MetS. 3) LDL/HDL ratio had association with BMI, WC, and MetS. Conclusion : We identified significant association between lipid ratios and cardiovascular disease risk factors. The three lipid ratios were particularly strongly associated with BMI, WC, and MetS.

The purpose of this study was to explore ways to revitalize the community-based child care community by identifying the factors that are hindering and activating the operation and use of this community by elementary school students. To this end, an in-depth interview survey was conducted of operators of child care communities in Jeollabuk-do and users of caring communities. Detailed themes, sub-ranges and upper ranges were determined through a qualitative research method. As a result of the study, it was determined that the basic environmental weakness of the caring community and its lack of power are the things hindering the operation and use of rhe communities the most. On the other hand, the main activation factors for community-based child care community activities were the stabilization of the environment and the strengthening of the internal capacity of the care community. This study is meaningful as basic data for the safe establishment and activation of a community-based child care community, which is emerging as an alternative to the child care gap due to the prolonged effects of COVID-19.

This study investigates time allocation among paid work, child care and leisure of dual earner parents of pre-school child. The focuses of this study are time allocation of full-time dual earner parents which can be affected by traditional gender role ideology, and if the gender effects can be diminished or not. So the analysis were about gender effects in the time allocation and the moderating effects of education on gender effects. According to the analysis, the hypothesis are partly corroborated. Even though gender is not effective on paid working time(production time), it affects the time allocation for child care and leisure. There are significant gender gaps in time share for child care(family time) and time share for leisure(private time). The education has moderating effects on gender effects. When education years getting longer, gender gap in child care time becomes narrow, however gender gap in leisure time becomes wide. Because the education is expected to cultivate the sense of value of child care, it can bring decrease of gender gap in care time. According to the result on leisure time share, the education is not expected to make changes in patriarchical gender role in terms of leisure and it doesn't contribute work and life balance.

This paper proposes an approach in modeling a 4x60inch Allis Chalmers Hydrocone Crusher [1] hydroset and presents some numerical simulation results. The mining and quarry industry is one of the industries which extensively use hydrocone crushers, which are a family of cone crushers, for rock size reduction. Field studies have proved that if proper control and management of these machines is undertaken, they can yield an increased production output of more than 30%, in addition substantial savings in both energy consumption per unit ton produced and manpower can be easily realized. In order to achieve these economic benefits, high performance from these machines is expected. Implementing automatic control for such machines would be a great leap towards achieving both economic benefits and more effective fool-proof predictive maintenance. But, unfortunately, for such a control system to be designed, it necessary to make a mechatronical model of this plant. The plant model is able to give us an insight into variations of both the plant gap setting (displacement) and system pressure due to variable loading arising from the crushing process.

The purpose of this study was to identify the formation and changing pattern of nursing perspectives of nursing students. 176 subjects were composed of 118 nusing students and 58 non-nursing students. The data were collected through openended question and structured questionair. The result were as follows : 1. Nursing perspectives were classified six categories(nature of nursing, image of nursing, component of nursing, meaning of nursing, range of nursing, function of nursing) 2. As increased major lecture period, the item of ${\lceil}$Nursing is helping${\rfloor}$ was changing positively. 3. As incresed clinical practice, the student's perception about items of ${\lceil}$Nursing has gap between theory and practice${\rfloor}$, ${\lceil}$Nursing is helping${\rfloor}$ was increased. 4. As increased self-concept, the students were considered the item of ${\lceil}$Nursing is action that giving knowledge and helping to effective coping for individual and group${\rfloor}$ significantly. 5. 1) The students having religion were considered the item of ${\lceil}$Nursing must doing politely${\rfloor}$ significantly relatively to the students don't have religion. 2) The students having experience of admission to hospital in their or their family had negative nursing perspectives. 3) Against the students who select nursing major for his high school perfoermonce and advice of their significant others, the students who select nursing major for service had positive nursing perspectives.

This study aimed to investigate the role of domain-specific causal mechanism information and domain-general conditional probability in young children's causal reasoning on psychology and biology. Participants were 121 3-year-olds and 121 4-year-olds recruited from seven childcare centers in Seoul, Kyonggi Province, and Busan. After participants watched moving pictures on psychological and biological phenomena, they were asked to choose appropriate cause and justify their choices. Results of this study were as follows: First, young children made different inferences according to domain-specific causal mechanisms. Second, the developmental level of causal mechanisms has a gap between psychology and biology, and biological knowledge was proved to be separate from psychological knowledge during the preschool period. Third, young children's causal reasoning was different depending on the interaction effect of domain-specific mechanisms and domain-general conditional probability: children could make more inferences based on domain-specific causal mechanisms if conditional probability between domain-appropriate cause and effect was evident. To conclude, it can be inferred that the role of domain-specific causal mechanisms and domain-general conditional probability is not competitive but complementary in young children's causal reasoning.

Purpose: The purpose of this study was to identify the relationship between marital satisfaction and the quality of life for women and men who live in a rural area in Korea through an international marriage. Methods: A descriptive correlational research design was used. Ninety-one women and 56 men were surveyed from May 1st., 2007 to April 6th., 2008. Data were analyzed by t-test, Pearson's correlation coefficients, and Fisher's exact test. Two types of questionnaires were used: Marital satisfaction scale (MSS) and WHO quality of life-brief (WHOQOL-BREF). Result: There is a gap between men's age and women's in the average of their marriage ; 37 vs 24. In addition, men's marital satisfaction was much higher than women's (t =2.16, p=.032) and quality of life was also higher than women's (t=-0.85, p=.005). According to this survey, therefore, it has been shown that there is a positive correlation between marital satisfaction and the quality of life (r =.435, p<.001). Conclusion: In order to improve the quality of life, marital satisfaction should be promoted by practical family nursing programs and it is necessary for the internationally married women to be continuously provided with language education and cultural awareness.

This study explored mothers' and grandmothers' perception regarding child rearing practices as overprotective behaviors for first to third grade levels of elementary school. The study was conducted on 202 mothers and grandmothers of first to third grade elementary school students. Questionnaires were made with 40 questions on overprotection behaviors selected from the existing questions for preschooler, high grade elementary students, and youth. The questionnaires were distributed to target subjects to answer how they would perceive when each of question is applied to their lower grade elementary students. Based on the collected responses and the factor analysis, it was found out that the overprotective behaviors were classified into four factors such as "reduction in independence," "over-sensitiveness to safety," "interference in daily life," and "health anxiety." There were significant differences in the perception of the overprotective behavior by the subjects depending on the generations, features of children and mothers. This study focused on the lower grade elementary school students who have been removed from studies due to the lack of intervention measures. It has the implication in that the findings of the study can give the basic data for the development of the scale on overprotective behaviors in lower grade elementary school students.

Purpose: This study was to explore the gap between awareness and performance toward evidence-based pain management in older adults for the purpose of establishing baseline data for evidence-based pain management protocol development and dissemination. Methods: The subjects were 290 staff nurses from three general hospitals. Self administered questionnaires were used to collect the data and the results of the study were analyzed with descriptive statistics, t-test, ANOVA and Pearson's correlation. Results: There were statistically significant differences between awareness and performance in pain assessment (t=17.31, $p$ <.001), patient and family education (t=17.33, $p$ <.001), pharmacologic management (t=12.99, $p$ <.001), non pharmacological management (t=16.28, p<.001), and evaluation of effectiveness (t=11.70, $p$ <.001). There were also statistically significant differences in awareness and performance according to the workplace, knowledge, and usual performance. Conclusion: The study showed that the hospital nurses' performance about evidence-based pain management in older adults was lower than their awareness level thus indicating significant gaps between evidence and actual practice. To ensure effective pain care, the factors contributing to these gaps need to be analyzed to identify the barriers. In addition, the evidence-based pain management guideline suitable for various clinical settings needs to be developed and disseminated.

Papermaking has changed remarkably during the past 20 years, creating huge pressures on retention and drainage programs. During this time, technology has advanced from single PAM flocculants to inorganic microparticle-based programs and then to micropolymer-based programs. In today's evolving fine paper market, retention and drainage programs have to meet increased demands in many areas, such as increased speed, GAP formers, dilution headboxes, higher ash levels, reduced furnish quality, lower cost, and increased machine efficiency. Hercules recently introduced a new technology that offers performance and stability improvements and operational cost savings as compared to existing advanced technologies. $PerForm(R)$ SP Advanced Retention and Drainage Technology consists of a family of products based on a structured organic particulate that offers papermakers the ultimate flexibility for management of wet end chemistry. This paper compares $PerForm(R)$ SP Advanced Retention and Drainage Technology to inorganic microparticle and micropolymer technologies and provides multiple case histories on machines that demonstrate the benefits of the technology. In these case histories, the PerForm SP is shown to provide improved retention and drainage that results in improved performance and operational cost savings to the mill.
