The microstructural evolution with isothermal stirring during semi-solid state processing of hypoeutectic Al-6.2wt%Si alloy was studied. Substructure of the individual primary solid particle in the slurry was investigated through transmission electron microscopy(TEM). Formation of subgrain boundaries on the rheocast Al-6.2wt%Si alloy is observed and the misorientation between the grains is shown typically under 2 degrees by analyzing selected area diffraction (SAD) and convergent beam electron diffraction (CBED) patterns. The existence of high angle grain boundaries are also observed in the alloy. Based upon these observations, mechanisms for the primary particles fragmentation are considered. With isothermal stirring, the dislocation density increases, and the evolution of dislocation cell structure takes place, which is interpreted as a process of achieving uniform deformation by dynamic recovery under applied shear stress.

The Shinbulsan wetland, located in Yangsan-si, Gyeongsangnam-do, South Korea, was designated as a conservation area in 2004. The area was monitored from 2015 to 2019 to investigate the community characteristics and changes of benthic macroinvertebrates. Between 2015 and 2016, several insects of the orders Ephemeroptera, Odonata, and Hemiptera were identified, but their numbers decreased significantly in 2017 and 2018 following the loss and recovery of the moor owing to drought. During this period, there were relatively more insects of the order Diptera. Within this order, three functional feeding groups, gathering-collectors, plant-piercers, and predators were investigated. Predator species were the most abundant (83.3%), whereas gathering-collectors accounted for the largest proportion of individual insects (50.5%). Between 2015 and 2016, when the moors were stable, groups I and III had the highest community stability. After 2017, when the moors had dried up, group III effectively disappeared because of its lower relative resistance and resilience, and only taxa belonging to group I remained. The results of this study indicate that benthic macroinvertebrates that adapt early during moor formation inhabit the Shinbulsan wetland.

This study aimed to identify factors that promote participation of rural women in community activities. A total of 466 rural women (effective recovery rate 84.6%) residing in rural areas from October 10 to October 14 in 2016 were surveyed. The main results of the study are as follows. First, the highest participation of rural women in community activities involved women farmers' organizations, which also showed the highest satisfaction. The purpose of their participation in community activities was for community service. Second, there were differences in participation among groups according to individual factors such as age, annual income, and occupation as well as value factors such as sense of community and life satisfaction. Third, with higher age and income and sense of community, rural women were more likely to participate in community activities.

The mass social trauma, such as organized violence, wars, oppression by dictatorships and massive terrorist attacks, exposes thousands of people to trauma in a short period of time. Therefore, the mass social trauma is distinguished from individualized trauma, such as a violent attack, rape or a traffic accident in that it results in multiple and extended consequences beyond the individual. During the Khmer Rouge regime, one quarter of the Cambodian population was killed as a result of malnutrition, forced labor and mass killings. Until now, its evil continues to affect Cambodian's physical and mental health problems. Although there is ongoing debate, to date, no consensus has been reached supporting a clear set of recommendations for the intervention and longitudinal study regarding the influence of killing field massacre being too little. And comparative cultural studies, such as comparing the East to West or other Asian cultures are also lacking. This article gives an overview of previous study results about the mental health of Cambodians, and suggests a possible research issue and therapeutic interventions to determine the impact of mass trauma to the members of society and post-traumatic recovery factors.

This study is on the design and evaluation of Zero Energy Solar House(ZeSH) including active solar heating system. Various innovative technologies such as super insulation, passive solar systems, super window, ventilation heat recovery system...etc were analyzed by individual and combination for the success of ZeSH. The ESP-r simulation program was used for this. Simulation results shows that almost 77% of heating load can be reduced with the following configuration of 200mm super insulation, super windows, passive solar system and 0.3 ventilation rate per hour. Active solar heating system (ASHS) was designed for the rest of the heating load including hot water heating load. The solar assisted heat pump is used for the auxiliary heating device in order to use air conditioner but not included in this study. The yearly solar fraction is 87% with a solar collector area of $28m^2$. The parametric studies as the influence of storage volume and collector area on the solar fraction was analyzed.

The purpose of this study was to investigate the necessary functions and areas of improvement in bras worn by patients during the initial three-month recovery period after a breast augmentation procedure, and a functional bra that fits properly was designed. In order to analyze the necessary functions, a bra was designed after relevant discussions with medical staff and patients who underwent breast augmentation surgeries and considering the advice from bra designers and clothing and textile experts. This bra was designed to protect the surgical scars and minimize the compression by inserting a nonwoven fabric into the shoulder and front parts. In addition, it was designed in a way that could fit the individual breast volume by using a mesh material partially on the upper side of the molded cups. Underwires that could support the breasts were inserted, and a detachable wire was used to suit the patient's needs and the diagnosis by the medical staff. As the bra designed in this study received excellent scores during the evaluation by research subjects and experts, it can be used for designing the prototype of a functional bra.

Using a method to correct redshift space distortion (RSD) for individual galaxies, we mapped the real space distributions of galaxies in the Sloan Digital Sky Survey (SDSS) Data Release 7(DR7). We use an ensemble of mock catalogs to demonstrate the reliability of this extension, showing that it allows for an accurate recovery of the real-space correlation functions and galaxy biases. We also demonstrate that, using an iterative method applied to intermediate scale clustering data, we can obtain an unbiased estimate of the growth rate of structure $f\sigma_8$, which is related to the clustering amplitude of matter, to an accuracy of $\sim 10\%$. Applying this method to the Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7), we construct a real-space galaxy catalog spanning the redshift range $0.01 \leq z \leq 0.2$, which contains 584,473 galaxies in the North Galactic Cap (NGC). Using this data we, infer $0.376 \pm 0.038$ at a median redshift z=0.1, which is consistent with the WMAP9 cosmology at $1\sigma$ level. By combining this measurement with the real-space clustering of galaxies and with galaxy-galaxy weak lensing measurements for the same sets of galaxies, we are able to break the degeneracy between $f$, $\sigma_8$ and $b$. From the SDSS DR7 data alone, we obtain the following cosmological constraints at redshift $z=0.1$ for galaxies.

In this paper, we analyze the current phenomenon of child abuse crimes based on the information gathered by the National Child Protection Agency. The purpose of this paper is to diagnose the seriousness of child abuse by biological parents based on the analyzed information and propose measures against it. Comprehensive and integrated measures are needed for child abuse committed by biological parents due to abuse concealment, continuity of damage, and inactive national intervention by considering punishment on attackers through national intervention, fundamental in-depth psychological counseling, therapeutic care, promoting recovery of victims, and ultimately continuous and regular management and monitoring as a long-terms measure. To do so, developing customized and individual educational programs and make them obligations can be first presented to identify child abuse in advance and build up preventive systems based on the principle of family preservation. In addition, problems should be addressed at a fundamental level by performing various and active therapeutic treatments such as psychological treatment, mental treatment, or drug treatment gradually and through phases for biological parents who commit child abuse and contributing to recovering the relationship. Furthermore, proper protection and treatment service should be provided to children victimized by abuse by extending professional children care facilities and adopting the professional family commission system as measures by separating family.
