Objectives: This study aimed to determine the associations between parental depression and early childhood development among children aged 36 months to 59 months in Indonesia. Methods: From Indonesia's Basic Health Survey (RISKESDAS) 2018, this study included 6433 children aged 36 months to 59 months and their parents. Maternal and paternal depression was examined using the Mini International Neuropsychiatric Interview survey instrument, which was previously translated into Indonesian. The study also used the Early Child Development Index to measure child development and its 4 domains (cognitive, physical, socio-emotional, and learning). Multivariate logistic regression analysis was performed to determine the association between parental depression and early childhood development. Results: Overall, 10.3% of children aged 36 months to 59 months were off-track for development. After adjusting for biological, parental, and social characteristics, children born to parents with depression were found to be 4.72 times more likely to be off-track for development (95% confidence interval, 1.83 to 12.15). Conclusions: Children of depressed parents were more likely to be off-track for development. The findings highlight the need for early diagnosis and timely intervention for parental depression to promote early childhood development.

In this study, the configuration and tension of a towing cable for side-scan sonar are predicted in an ambient flow and at an unsteady towing condition. The governing equation of three-dimensional dynamic analysis for a flexible cable is solved using a finite difference method. We successfully predict the configuration and tension of a side-scan sonar and designed the towing system. It is found in static analyses that the side-scan sonar must be towed to keep a its stable depth at a reasonable speed. The study also reveals in the transient analyses that the dominant component affecting the top tension is the tangential drag force for the larger towing speed than the critical speed, and the self weight of a towed instrument for the smaller towing speed than. It should be maneuvered for a towing vessel with good consideration for the impact effect in a cable due to tension peak when a towing speed is suddenly increase. The developed program can be applicable for three-dimensional dynamic analysis of a towing system for various marine survey instruments.

The aim of this study was to assess a dietary status and to examine the factors related to the prevalence of metabolic syndrome in Korean children and adolescents. For this study, 5,576 subjects aged 10~18 years, who participated in the health and dietary intake survey (24h recall method) of the 2007~2013 Korea National Health and Nutrition Examination Survey (KNHANES), were sampled. The five components for the diagnosis of metabolic syndrome in the subjects were taken from the modified NCEP-ATP III. The total prevalence of metabolic syndrome among the subjects was 4.6%. The total prevalences of the metabolic syndrome components among the subjects were central obesity 8.4%, hypertriglyceridemia 18.8%, low HDL-cholesterol 13.4%, hypertension 22.4%, and hyperglycemia 5.2%. The gender, age, weight status, frequency of daily meals and eating-out frequency of subjects affected the prevalence of metabolic syndrome. Based on these results, There should be to improve the dietary guidelines and nutrition education to decrease the prevalence of metabolic syndrome for Korean children and adolescents.

The distributions of demersal fish along the coast of the South Sea, Korea, were estimated from a hydroacoustic survey and bottom trawl catches in April of 2015. Acoustic data were collected at 38 kHz, and converted into the nautical area scattering coefficient (NASC, m²/n·mile²) for 0.1 n∙mile along eight transects during day and nighttime. Various demersal fish species were collected and the dominant species comprised no more than half of the catch. The estimated acoustic density of demersal fish compared well with the cumulative catch weight from bottom trawl catches in daytime, but showed a low correlation at nighttime. The NASC of pelagic fish determined for anchovy was correlated with water temperature. The combined hydroacoustic and trawl method can be used to understand the spatial/temporal structure and estimate the density of demersal fish in coastal areas.

The purpose of this study is to research and development of 'Korea B(Benefit)-impact Model' for Sustainable Development. A concept evaluation model is 'B(Benefit)-impact model' in U.S.A. We use the results of surveys that examined the importance of social value issues to stakeholders in Korea to implement the benefit-impact model in Korea. In particular, in this paper, we use the KSI(Korean Sustainability Index) survey data conducted by the Korea Standards Association to evaluate the social value of the construction industry for representative stakeholders in the construction industry. The social value pool and the activity indicator pool used for the survey are created based on relevant International Standards; ISO 26000, ISO 14001, ISO 37001. As a result, Korea B-impact model for construction industry included the following five core social value issues; Strengthen transparency of corporate management, Ensure fair employment and employment relations, Efforts to prevent corruption, Conduct fair competition, Efforts to prevent environmental pollution. In addition, the US B-impact model has three limitations. First, it is unclear whether the key indicators have been derived while considering all issues of social value. Second, US B-impact model indicators are developed by the social responsibility experts, so it is necessary to review by stakeholders in each industry. Finally, it would be more effective for companies to use the B-impact model index as a more detailed activity indicator. When developing a Korea B-impact model, the following methods are used to supplement it. First, we reviewed all social value issues using international standards. Secondly, we used the KSI(Korean Sustainability index) survey results to derive the importance of the social value issue of construction industry in Korea. Finally, we have clearly matched the activity indicators by social value core issues based on the GRI Standard so that companies can actually use the Korea B-impact model for the construction sector. The detailed development stages and results of this study are as follows;.
