항만연관산업과 최저임금간의 생산성 및 고용효과에 대한 상관관계를 분석한 결과, 그 효과는 매우 미미한 것으로 나타났다. 그러나힝민연관산업의 상용근로자와 임시근로자, 자영업자 및 기타 근로자에 대해서는 다소 차이를 보이고 있다. 즉 상용근로자는 다소 안정적인 반면에, 임시직과 자영업자에게는 다소 부정적인 효과를 미치는 것으로 나타났다. 최저임금위원회에서 최저임금의 인상은 노동시장에서 소득효과와 대체효과 간의 상호작용에 의하여 안정적인 모습을 보이고 있다. 항만연관산업은 최저임금 인상이라는 변수보다 오히려 세계적인 경기불황, 국내 경기의 변동성에 더 영향을 받는 것으로 분석되었다.

Objective: The purpose of this study was to analyze the effects of infant temperament on adaptation at childcare centers and the moderated effects of teacher-infant relationships between a vertical transition group and horizontal transition group. Methods: The subjects of the study were 284 infants, aged 1-years-old and 2-years-old, who were hospitalized in childcare centers. To investigate the correlation between variables, Pearson correlation analysis was used. Regression analysis was performed to check the effects of temperament and teacher-infant relationship on childcare adaptation. Results: Infant temperament influenced childcare adaptation in both vertical and horizontal transition groups. The quality of teacher-infant relationships was found to moderate the relationship between infant temperament and childcare adaptation in both groups. Conclusion/Implications: The results of this study, which showed different moderating effects of the teacher-infant relationship in the vertical transfer group and the horizontal transfer group, suggest the need for more diverse studies on the various transition experiences regarding childcare transition.

This study attempted to investigate the mediating effects of self-efficacy in the influence of appearance management behavior and life satisfaction among middle-aged women. For this, a questionnaire survey was performed among 153 women aged 40-59 living in Seoul and Gyeonggi-do. The collected data were analyzed by frequency analysis, cross-tabulation analysis, t-test, ANOVA, Duncan's test, reliability analysis, and correlation analysis, using SPSS 25.0. To examine mediating effects, SPSS Process MACRO #4 was borrowed, and the results found the following: 1) A positive correlation with statistical significance was observed among appearance management behavior, self-efficacy, and life satisfaction. 2) According to the analysis of appearance management behavior, self-efficacy and life satisfaction by demographic characteristics, some differences were found. 3) The mediating effects of self-efficacy in appearance management behavior and the life satisfaction relationship was confirmed. The above results show that middle-aged women experience an increase in self-efficacy through appearance management behavior and improvements in their life satisfaction through such self-efficacy, not just enhancing life satisfaction through appearance management behavior. In other words, appearance management increases life satisfaction through an ego-discovery process.

Objectives : Network pharmacology-based research is one of useful tool to predict the possible efficacy and molecular mechanisms of natural materials with multi compounds-multi targeting effects. In this study, we investigated the functional underlying mechanisms of Astragalus membranaceus Bunge (AM) on its anti-obesity effects using a network pharmacology analysis. Methods : The constituents of AM were collected from public databases and its target genes were gathered from PubChem database. The target genes of AM were compared with the gene set of obesity to find the correlation. Then, the network was constructed by Cytoscape 3.9.1. and functional enrichment analysis was conducted to predict the most relevant pathway of AM. Results : The result showed that AM network contained the 707 nodes and 6867 edges, and 525 intersecting genes were exhibited between AM and obesity gene set, indicating that high correlation with the effects of AM on obesity. Based on GO biological process and KEGG Pathway, 'Response to lipid', 'Cellular response to lipid', 'Lipid metabolic process', 'Regulation of chemokine production', 'Regulation of lipase activity', 'Chemokine signaling pathway', 'Regulation of lipolysis in adipocytes' and 'PPAR signaling pathway' were predicted as functional pathways of AM on obesity. Conclusions : AM showed high relevance with the lipid metabolism related with the chemokine production and lipolysis pathways. This study could be a basis that AM has promising effects on obesity via network pharmacology analysis.

It is a long known fact that there exists a tight correlation between far-infrared and radio emission both for galaxies hosting active galactic nuclei and for star forming galaxies. We probe the radio - infrared correlation for a sample of extragalactic sources constructed by the cross-correlation of the AKARI/IRC All-Sky Survey Point Source Catalogue, the AKARI/FIS All-Sky Survey Bright Source Catalogue, and the NRAO VLA Sky Survey. Additionally, all objects of our sample were identified as galaxies in NED and SIMBAD databases, and a part of them is known to host active galactic nuclei (AGNs). After remeasuring all the fluxes, in order to avoid small aperture effects, we compare the ratio of radio to infrared emission from different types of extragalactic sources, and discuss the FIR/radio correlation as seen by AKARI and make a comparison to the previous results obtained thanks to IRAS.

A capillary tube, which is a common expansion device in small sized refrig-eration and air-conditioning systems, should be redesigned properly to establish an optimum operation cycle of a refrigerating system with alternative refrigerants. Based on experimental data for R-22, R-290, and R-407C, an empirical correlation is developed to predict mass flow rate through capillary tubes. Dimensionless parameters are derived from the Buckingham Pi theorem, considering the effects of operating conditions and capillary tube geometry on mass flow rate. Approximately $97\%$ of the present data are correlated within a relative deviation of $\pm\;10\%.$ The present correlation also predicts the data obtained from open literature within $\pm\;15\%.$ In addition, rating charts of refrigerant flow rate for R-12, R-22, R-134a, R-152a, R-407C, R-410A, R-290, and R-600a are developed.

When a mechanical structure is driven by stationary wide band random point forces, the resulting vibration depends upon the number, location, and joint statistical properties of the exciting forces. In this study, under the assumption of light damping, an approximate procedure for analyzing plates is briefly outlined. The effects of number, location and correlation of the force field on the vibration level are then investigated for various cases in which random point forces with band limited white noise are applied, and the optimal spacing between input forces that produces a relative minimum in the vibration response is predicted.

One of the representative side effects in current information and knowledge society is internet addiction. Nowadays single-parent families become popular due to various reasons such as increasing divorce ratio and government supports for single-parent family. National research works showed that internet addiction ratio of single-parent family children is higher than that of children of intact families. The research purpose of this paper is to investigate correlation between internet addiction and parent types. For this purpose, extensive and national survey works of NIA(National Information Society Agency of Korea) are collected and analyzed. Based on statistical analysis work, it is concluded that there is no meaningful correlation between internet addiction and parent types.
