The purpose of this study was to investigate the influence of household income on children's academic achievement, and to identify the mediating effects of parental time and material investment in the relationship between the two variables. We utilized the third-wave data of the "Seoul Panel Study of Children Surveys(SPSC, 2006)". The major findings of the present study are as follows. First, the results show that household income has a positive influence on children's academic achievement. Second, parental material investment fully mediates the influence of household income on children's academic achievement. Among the variables representing parental material investment, the mediating effects of "purchasing of cognitively stimulating materials" and "participating in extracurricular activities' are found to be statistically significant. However, the two variables representing parental time investment ("parent activities with child out of home" and "parent involvement in school") do not have any significant influence on children's academic achievement. These results indicate that the influence of household income on children's academic achievement can be better explained by parental material investment rather than parental time investment. Implications for policy and practice are discussed.

The welfare of horses depends on satisfying both the physiological and psychological needs of the animal. The object of this study was to evaluate fence safety at the horse farm. A Thoroughbred colt with cribbing was found dead in a paddock. The fence of paddock is a four-pipe fencing. He cribbed the 2nd pipe from the top. But he couldn't pull his face because his incisors acted as hooks and two ramuses of the mandible was entrapped in a top pipe. So he was embarrassed and went down while he terribly struggled to get out his face. Finally, he was strangulated to death. Safe fencing is essential on a horse farm. The function of these fences are to protect the horses but it was more of a hazard. In order to safe management of horses, facial length of the horse and the pipe interval of the fence should be considered. Further research is needed to put a muzzle on the horses while they are at a paddock. This study provides important benchmarks for the equine industry to consider fence type and evaluate fence safety.

Many countries have interested animal welfare. Similarly, domestic people have concern for the welfare from companion animals to livestock. Environmental enrichments (EE) are tool to enforce the welfare, however, research with sows is limited. Therefore, this study was investigate to effects of environmental enrichments on performance and behavior properties of gestating sows. A total of 30 pregnant sows (Landrace) were assigned into three treatments that control, T1 (plastic device) and T2 (Rice straw). Period of trial was from Mar. 03. 18. to Mary 19. 18. The EE were allotted to center of experimental pen ($11.6{\times}6.0m$). Body weight (BW), backfat thickness (BF) and cortisol were identified at experimental initial or end date. Behavior was recorded during 24 hours on days 91 of gestation, and then analyzed the patterns. BF was reduced (15.73 vs. 16.56 mm; p>0.05) in T1 than control, but Ending BW, total litter size and alive piglets did not differ. Born dead piglets showed lower tendency (1.00 and 0.63 vs. 1.50 heads; p>0.05) in T1 and T2 than control. Similarly, the enrichments declined farrowing mortality (C, 8.68%; T1, 6.86%; T2, 3.40%; p>0.05). Cortisol was not differed among treatments. In the behavior characteristics, eating showed lower (1.81 vs. 9.68 and 6.99%; p<0.05) in T2 than control and T1. Furthermore, playing or digging were only observed (0.33 and 2.10%; p<0.05) in T1 and T2, respectively, whereas rubbing (0.91%, p<0.05) only showed in the control. These results suggest that the provision of EE would be not negatively affected the performance of the gestating sows and could be led to improvement of the livestock welfare.

The skin barrier is an important part of an ostomy product, holding the ostomy bag in place and protecting the peristomal skin. Skin barriers help protecting the peristomal skin from excrements and secretion, thus keeping the skin physiology intact by absorbing or permeating sweat. The vocabulary for the skin barrier has been standardized by ISO 24214, but there is no standard related to the skin barrier in Korea. We investigated the academic and commercial documents related to the skin barrier, and conducted a survey for appropriate korean vocabulary for standard. We propose Korean standard vocabulary for skin barrier terms defined in ISO 24214:2006.

Urine and/or feces disposal systems are expected to replace the diapers currently used for urine and feces disposal for the elderly with urinal and/or fecal incontinence. The are designed to detect the urine and/or feces, cleanse the excremental body organs with water transported from a cleansing water container in the main body, suction them into a fluid waste storage container for future disposal, and dry the area with hot air supplied also from the main body. These systems thus could relieve the chores of a caregiver and could also enhance the patient's hygiene. We reviewed in this paper the detection systems of urine and feces, the main components of the urine and feces disposal systems, and tried to classify the systems currently available in the market.

This study aimed to understand the meaning and essence inherent in the life experiences of people with schizophrenia. We approached with phenomenological method, and the research participants were 10 adults, aged 20 or older, who were diagnosed with schizophrenia. As a result, we found four essential themes. The participants with schizophrenia lived a life with special constraints of being thrown to the reality in which they experienced continuing suffering. Nevertheless, their daily lives were maintained on the basis of their own feelings and needs. In this study, we confirmed that they should be understood and treated in the mental health field with the perspective that they are not 'patients' nor a pathological outcome, but a 'human' with schizophrenia.

In recent years, active research has been devoted toward developing a monitoring system using ambient vibration data in order to quantitatively determine the deterioration occurring in a structure over a long period of time. This study developed a low-cost edge computing system that detects the abnormalities in structures by utilizing the dynamic characteristics acquired from the structure over the long term for ensemble learning. The system hardware consists of the Raspberry Pi, an accelerometer, an inclinometer, a GPS RTK module, and a LoRa communication module. The structural abnormality detection afforded by the ensemble learning using dynamic characteristics is verified using a laboratory-scale structure model vibration experiment. A real-time distributed processing algorithm with dynamic feature extraction based on the experiment is installed on the Raspberry Pi. Based on the stable operation of installed systems at the Community Service Center, Pohang-si, Korea, the validity of the developed system was verified on-site.

The purpose of this meta-analysis was to address two questions: (1) To what extent are types of child abuse related to psycho-social maladjustment of the abused? (2) Do relations found in this study vary by the gender, sample size, year of publication, types of publication, and respondents' age? The materials of this study were based on 14 variables obtained from 104 published and unpublished (doctoral disserations and master's theses) research papers over a span of 26 years(1990-2016). Child abuse related variables were categorized into physical abuse, emotional abuse, neglect, and abuse while psycho-social maladjustment grouped as internal (anxiety, depression, withdrawal, and anxiety/depression) and external problem behaviors(aggression, problem behavior, and delinquency). Major findings were: Medium effect size of emotional abuse, abuse, physical abuse, neglect on psycho-social maladjustment among the abused were calculated. Emotional abuse was highly related to every internal and external problem behaviors. Neglect was found to have higher effect size in external problem behaviors than internal problem behaviors. Publication types moderated the association between types of child abuse and internalization while year of publication, number of samples and publication types showed moderation effects on the relation between types of child abuse and externalization. Finding suggest that future studies on child sexual abuse and those on intervention outcome are required and use of well validated instruments are essential.

Objective: This study aims to thoroughly analyze the correlation effect size between domestic violence and school violence by meta-analyzing previous studies on the correlation between school and domestic violence. Methods: For this purpose, meta-analysis was performed on the selected research material, which consists of national research data collected from various databases from 2001 to April, 2019. 16 thesis and 9 papers on the correlation between school and domestic violence were selected. A random effect model analysis based on the homogeneity examination results was performed on the selected data. Results: The results showed, just as Cohen (1977) proposed, that the correlation effect size between domestic and school violence was 0.25, which is moderate. This is a somewhat lower number than the previous studies on the same subject presented. Of the sub-categories of domestic violence, physical violence and psychological violence appeared to have a correlation effect size of 0.34 and 0.28, respectively, with physical violence showing the highest correlation effect size. Of the types of domestic violence, witnessing spouse violence and experiencing neglect appeared to have a moderate correlation size effect of 0.24. All of these results were statistically significant. Conclusion/Implications: This study utilized meta-analysis as a comprehensive and systematic method to analyze the correlation effect between domestic and school violence. The results presented may lead to discussions on the subject's social implications, limits, and propositions for future studies.
