A ground-source heat pump system (GSHP) is more energy efficient than other heat-source systems because it uses annual constant underground and water temperatures. Especially, two-well geothermal systems using groundwater as the heat source can achieve higher performance than closed-loop geothermal systems. However, performance of two-well geothermal systems is decreased by occurring overflow according to scale during long-term operations. Therefore, this study presents a two-well pairing geothermal system that controls the groundwater level of a diffusion well. In addition, a two-well pairing geothermal system and an SCW geothermal system were installed, and a comparative analysis of cooling performance depending on system operation under the same load conditions was conducted. The result was that the average heat pump coefficient of performance (COP) of the two-well pairing system was 6.5, and the entire system COP was 4.3.

This study aims to explore the men's perceived meanings attached to the father role and to investigate the relationship between the father role meanings and men's psychological well-being. Using two waves of data from the National Survey of Families and Households (NSFH) across 5 years, this study estimated the influences of the father role meanings at T1 on psychological well-being of fathers at T2 with hierarchical Ordinary Least Square (OLS) regression models. Findings showed that the majority of fathers felt the father roles interesting, appreciated, sociable, and well-done. However, stepfathers reported significantly more negative meanings of the father role than fathers having biological children. Positive role meanings attached to the father role in terms of interesting and well-done were Significantly associated with men's psychological well-being. Although this study has some limitations by using the secondary survey data (NSFH), this study has an advantage in exploring the association between fatherhood experiences and men's psychological well-being from men's own perspectives. Also, this study has strength in a sense that long-term effects of the father role meanings were investigated and empirically provide findings in consistent with role identity.

This study examined the various pathways from peer relationships to subjective well-being through self-esteem in late childhood. A total of 354 fifth and sixth grade students in elementary school (189 boys and 165 girls) participated in the study. Peer relationships were assessed using the peer rating scale, and self-esteem and subjective well-being were measured using the self-rating scales. The data were analyzed by means of Structural Equation Modeling (SEM). Children's peer relationships affected their subjective well-being directly, as well as indirectly through their self-esteem. Positive relations with peers enabled children to improve their subjective well-being. In addition, those children who possessed good relationships with peers were more likely to perceive themselves as worthy, which led to higher overall levels of happiness and satisfaction in their lives. The study emphasizes the crucial influence of self-esteem on school-aged children's subjective well-being.

Optical gain characteristics of $1.3{\mu}m$ type-II GaAsSb/InGaNAs/GaAs trilayer quantum well structures were studied using multi-band effective mass theory. The results were compared with those of $1.3{\mu}m$ GaAsSb/InGaNAs/GaAs trilayer quantum well structures. In the case of $1.3{\mu}m$ GaAsSb/InGaNAs/GaAs trilayer quantum well structure, the energy difference between the first two subbands in the valence band is smaller than that of $1.3{\mu}m$ GaAsSb/InGaNAs/GaAs trilayer quantum well structure. Also, $1.3{\mu}m$ GaAsSb/InGaNAs/GaAs trilayer quantum well structure shows larger optical gain than $1.3{\mu}m$ GaAsSb/InGaNAs/GaAs trilayer quantum well structure. This means that GaAsSb/InGaNAs/GaAs system is promising as long-wavelength optoelectronic devices for optical communication.

This study explored pathways from mothers' beliefs to children's subjective well-being through children's private after-school activities and stress levels. A sample of 230 6th grade elementary school students (125 boys and 105 girls) in Seoul completed questionnaires on children's stress and subjective well-being. Their mothers responded to questionnaires on mothers' beliefs and children's private after-school activities. Data were analyzed by means of Pearson's correlation coefficients and multiple regression analyses. Our results demonstrated that mothers' beliefs indirectly influenced children's subjective well-being through both children's private after-school activities and stress levels. Neither children's private after-school activities nor children's stress mediated between mothers' beliefs and children's subjective well-being. Mothers' beliefs also had a direct effect on children's subjective well-being. Significantly, both mothers' beliefs and children's stress played crucial roles in improving children's subjective well-being.
