문재인정부의 국민생활비절감을 위한 수도권광역급행철도 GTX의 합리적인 운영방안에 대한 연구
안혜령(安彗伶),강인성(姜仁成) 한국공공관리학회 2018 한국공공관리학보 Vol.32 No.4
2018년 통계청 조사에 따르면 2017년 우리나라 가구당 월평균 소비지출은 255만 7천원이며 지출 항목가운데 교통비 지출이 가장 많은 비율을 차지하는 것으로 나타났다. 이러한 가계경제의 현실 속에서 2017년 문재인 정부는 서민과 중산층의 민생경제를 위한 정책의 일환으로 교통비 절감을 통해 가계경제의 안정을 도모하고자 수도권 광역 급행철도의 단계적 착공이라는 국정과제를 제시하였다. 수도권 광역 급행철도의 운영에 관한 이론적 고찰을 통해 경제적 타당성, 대중교통 서비스의 형평성, 역사와 도심간의 공간적 접근성 확보 등이 중요한 요인들로 파악되었다. 이 세 가지 주요 영향요인들을 경제성, 형평성, 편의성이라는 분석 기준으로 설정하여 국민 생활비 절감을 위한 GTX의 효율적 운영방안의 측면에서 분석하고자 하였다. 분석 결과, 첫째, 경제성 부분에서 GTX의 요금으로 제안된 4가지 요금제의 평균값이 현행 대중교통과 자가용을 이용할 때 보다 저렴한 것을 확인할 수 있었다. 둘째, 형평성 기준에서는 GTX 노선이 지역별 인구수를 비례적으로 반영하지 못했다는 문제점을 발견하였다. 셋째, 편의성 부분에서는 공간적 편의성의 경우 동탄역의 공간적 편의성 개선이 시급했고, 시간적 편의성의 경우에는 국내외 고속열차와 비교해 속도의 향상으로 시간 단축적인 측면에서 경쟁력을 확보하는 것으로 나타났다.

This study was conducted to evaluate the effect of substitution of the flour with coffee silver skin (at the levels of 0%, 3%, 5%, and 7%) on the characteristics of yellow layer cake. The specific gravity of batter increased significantly as the content of silver skin increased. The specific volume of cake decreased significantly as the content of silver skin increased. The volume index decreased significantly as the silver skin content increased, while the symmetry index and uniformity index were not influenced. It was found that control had the highest cake indexes. Texture analysis showed that control had the lowest hardness and highest springiness. Hardness value of cakes was increased by adding silver skin; however, the springiness value of cakes with silver skin decreased during storage. According to sensory evaluation, experiment groups scored the higher points in texture acceptance than control. Above all, SS5 scored the highest points in aroma, taste and SS3 scored the highest points in appearance and overall acceptance.
정보의 직관부합성과 설명의 유형에 따른 유아의 정보 평가: 물리 · 생물 현상에 대한 정보의 타당성

Objectives: This study aimed to investigate whether children’s evaluation of information provided by an informant differs depending on the intuitiveness of the information provided, the presence of and types of additional explanations, and the age of the child. Methods: The participants were 158 children, aged 4 to 5 years, from eight child-care centers located in Seoul and Gyeonggi Province. Each child was interviewed individually, after completing a pre-test for measures of language comprehension. Results: First, when the informant provided information on physical and biological phenomena, children were more likely to evaluate intuitive information as plausible, compared to counterintuitive information. In addition, 5-year-olds were less likely than 4-year-olds to evaluate counterintuitive information as plausible. Second, after an explanation was added, children were more likely to evaluate counterintuitive information as plausible, when this explanation was causal rather than descriptive or circular. Third, the addition of an explanation was likely to result in the evaluation of intuitive information as less plausible, and counterintuitive information as more plausible. Conclusion: Based on childrens evaluation of information about physical and biological phenomena presented to them, this study confirmed that 4- and 5-year-old children were able to independently evaluate the plausibility of information, depending on the intuitiveness of the information, and the presence of and types of explanations. It also revealed that with increasing age, children become more skeptical about the plausibility of counterintuitive information, and demonstrated epistemic vigilance even when presented with intuitive information with an explanation.

The purpose of this study is to determine potential effectiveness of sourdough starter powder (made of Korean wheat flour) in the quality characteristics of bread and in the substitution effect of a dough improver in bread baking. The bread containing sourdough starter powder was considered to be most suitable for making sourdough bread. As a result, SP 10 showed the best fermentation rate and the highest volume and specific volume. In sensory testing, SP 10 was most preferable among others. According to experimental comparison between optimal addition ratio of SP 10 and other sourdough starter powder products available in Korean domestic market, SI had the highest fermentation rate, highest volume and specific volume. Analysis of texture showed that SI was soft with the lowest hardness and the highest elasticity. Sensory test showed that SI was most preferable of all, and SP 10 was more preferable than BP. It was concluded that SP 10 was not less preferable in the aspect of preference at sensory test than other products. Hence, it is expected that sourdough starter powder made of Korean wheat flour will be possibly more popular and effective in replacing some portion of dough improver of baking.

Objective: The purpose of this study was to examine the parallel dual mediating effects of positive and negative affects in the relationship between adult attachment and self-compassion of teachers in the early childhood education and care centers. Methods: Two hundred and six teachers participated in the survey who were recruited from kindergarten and child care centers in Seoul and five provinces in South Korea. The data were analyzed by means of frequency, percentages, Cronbach’s reliability coefficient and Pearson’s correlation using SPSS 25.0 and model 4 provided in The PROCESS macro for SPSS 3.4 version. Results: First, the teachers’degrees of anxiety and avoidance in their adult attachment were below the median scores. Those of positive and negative affects, and their self-compassion were close to the median scores. Second, there were parallel dual mediation effects of positive and negative affects between anxious attachment and self-compassion of teachers. Meanwhile, only positive affect had a mediating effect in the path of teachers’avoidant attachment and self-compassion. Conclusion/Implications: This study confirmed that it is important to raise positive affect by lowering each level of anxiety and avoidance in their attachment for teachers in order to improve their self-compassion. It implied the need to provide support for attachment stability enhancement and to pay attention to improve their self-compassion.
