Support policies such as education and training for re-employment of career-interrupted women are being implemented, but they are not being effectively employed. In addition, it is difficult for women with high educational background to re-enter, such as having to revise their previous careers or plan a new career for re-employment. In the previous studies, there was insufficient research to solve fundamental problems for re-employment, such as promising jobs with high employment opportunities. Therefore, when developing a curriculum for women with career interruptions, it was felt the need to select educational occupations that would be helpful in finding employment by age and educational background of the trainees. In this study, data on vocational training education of women with career interruptions were used to analyze the educational occupations with the highest employment rate by age and educational background.

The LNG carriers have been propelled by steam turbines and the LNG boil-off(BOG) has been used as fuel or vented. However, as the alternative propulsion systems such as diesel engines are being equipped on the LNG carriers for better fuel efficiency, a need for the LNG BOG re-liquefaction system that liquefies the BOG and sends the liquid BOG back to the LNG cargo has arisen in recent years. This study investigates the design of the BOG re-liquefaction system based on the reverse Brayton refrigeration cycle. The thermodynamic and heat exchanger analysis are carried out and the limitations to the system performance are discussed.

Background: The purpose of this study is to investigate the pro-con of re-implementation by administrative areas and the difference in perception of community water fluoridation in implemented and non-implemented areas after the community water fluoridation in Korea was suspended. Through this, we intend to provide basic data that can help find ways to increase the support and interest of local residents. Methods: The 601 questionnaires collected through the survey and statistical analysis was conducted using SPSS Statistics 28.0. Results: As a result of analyzing the perception of the community water fluoridation according to the understanding of fluorine, the proportion of people who were not recognized by both fluorine and community water fluoridation was the highest (p<0.05). As a result of the analysis of the pro-con of re-implementation of community water fluoridation, the approval was high. Among those who responded in favor, the place of re-implementation showed that 'implementation nationwide' was high. As for the reason for favor, it was found that it was possible to prevent dental caries disease. The reason for the objection was the lack of knowledge about fluoride. Conclusion: The results of the survey for the pro-con of the re-implementation of community water fluoridation showed a higher degree of 'agree' and showed that people in the area where community water fluoridation was not implemented showed higher interest in oral health prevention and management. Through this, not only oral education, but also correct information on the implementation method of community water fluoridation, the benefits of community water fluoridation, and the facts that were misunderstood in the past, as well as oral education, can be provided to raise interest in community water fluoridation. It is thought that the expected effect of the re-implementation of community water fluoridation can be obtained if such activities are carried out.

Purpose: The purpose of this study was to identify the retention effects of an individualized dietary education program for hemodialysis patients on diet knowledge, diet self-care compliance, and physiological indices, thus to find the most effective time period for re-education. Method: This study utilized one-group repeated pretest-posttest design. The participants were 52 hemodialysis patients in C hospital, Gyeonggi-Do. Data were collected at 4 and 12 weeks after the education from January through April 2016. Results: There was significant increases in diet knowledge even 12 weeks after the education (p= .007). Diet self-care compliance showed a significant increase at 4 weeks (p= .001), but a decrease at 12 weeks after the education. The level of blood natrium was significantly decreased between 4 and 12 weeks after the education (p= .006). The weight was significantly decreased at 12 weeks after the education. Conclusion: It has been identified that re-education for hemodialysis patients should be implemented between 4 and 12 weeks after education in order to maintain patients' diet self-care compliance, an ultimate aim of diet education. By helping them with their self-care compliance, the patients would maintain their physical and psychological function optimally, thus contributing to a better quality of life among hemodialysis patients.

Background and Purpose: The Montreal Cognitive Assessment (MoCA) has been known as a screening test for detecting mild cognitive impairment (MCI) better than Mini-Mental State Examination (MMSE). However, in previous domestic studies, no significant difference was found in the discriminability between MoCA and MMSE. Researchers have suggested that this might be because older Koreans are less educated than older Westerners. This study was conducted to examine the effect of education on the discriminability of MoCA compared to the MMSE. Methods: Participants were 123 cognitively normal elderly, 118 with vascular MCI, 108 with amnestic MCI, 121 with vascular dementia, and 113 with dementia of the Alzheimer's type. The Korean-MoCA (K-MoCA) and Korean-MMSE (K-MMSE) were administered. Multiple regression analyses and receiver operating characteristic (ROC) curve analyses were performed. Results: In all participants, education significantly affected both K-MoCA and K-MMSE scores along with age. The effect of education was re-examined by subgroup analysis after dividing subjects according to the level of education. Effect of education on K-MoCA and K-MMSE was only shown in the group with <9 years of education. ROC curve analyses revealed that the discriminability of K-MoCA to differentiate between vascular MCI and normal elderly was significantly higher than that of K-MMSE. When re-examining subgroups divided by education level, however, this higher discriminability of K-MoCA disappeared in the group with <9 years of education. Conclusions: These results indicate no difference in discriminating cognitive deficits between K-MoCA and K-MMSE in Korean elderly with <9 years of education.

The purpose of this study is to investigate the effect of positive psychological capital on re-employment attitudes of youth in their 20s dealing with an unemployment rate of more than 10%. The effect of positive psychological capital on attitudes for re-employment was analyzed by domain, and is based on variables of positive psychological capital composed of self-efficacy, hope, resilience, and optimism. As a result, hope (3.64) was the highest on the scale; however, resilience (at 3.37) was the lowest. In the analysis of positive psychological capital, the university graduate group (3.89) was the highest. But, the high school graduate group (3.25) was the lowest. In the results for re-employment attitude based on education level, the university graduate group (4.93) was the highest, but the high school graduate group (3.80) was lowest. The main variables influencing re-employment attitude were (in order): hope, optimism, self-efficacy, and resilience. These factors have an explanatory power for the four variables of around 25%. Overall, young adults (in their 20s) have higher levels of positive psychological capital because they have a higher education level. Also, higher educated re-employed applicants have higher positive psychological capital and attitudes for re-employment, compared to the other groups.

A graphene-Zn/Al layered double hydroxide composite film was simultaneously prepared by electrochemical deposition on the surface of a glassy carbon electrode (G-LDH/GCE) from the mixture solution containing GO and nitrate salts of $Zn^{2+}$ and $Al^{3+}$. The modified electrode showed good electrochemical performances toward the simultaneous electrochemical detection of hydroquinone (HQ), catechol (CA) and resorcinol (RE) due to the unique properties of graphene (G) and LDH such as large active surface area, facile electronic transport and high electrocatalytic activity. The redox characteristics of G-LDH/GCE were investigated with cyclic voltammetry and differential pulse voltammetry. The well-separated oxidation peak potentials, corresponding to the oxidation of HQ, CA and RE, were observed at 0.126 V, 0.228 V and 0.620 V respectively. The amperometric response of the modified electrode exhibited that HQ can be detected without interference of CA and RE. Under the optimized conditions, the oxidation peak current of HQ is linear with the concentration of HQ from 6.0 ${\mu}M$ to 325.0 ${\mu}M$ with the detection limit of 0.077 ${\mu}M$ (S/N=3). The modified electrode was successfully applied to the direct determination of HQ in a local tap water, showing reliable recovery data.
