본 연구는 제15차(2019) 청소년건강행태조사의 원시자료를 활용하여 생물-심리-사회 모델을 바탕으로 우리나라 청소년의 편의식품 섭취 경험의 영향요인을 파악하고자 하였다. 연구 결과 생물학적 요 인으로 성별, 학년, 아토피 피부염이 주요 요인으로 분석되었으며, 심리학적 요인으로는 스트레스 인지 수 준, 우울감 경험, 자살 생각 여부, 주관적 수면충족, 주관적 건강상태, 신체활동, 현재 흡연과 음주 경험이 영향요인으로 확인되었다. 또한 사회학적 요인으로는 영양 및 식이 교육, 아침식사 여부, 학업 성적, 주관 적 경제상태, 동거가족 여부가 청소년의 편의식품 섭취 경험에 영향을 미치는 것으로 나타났다. 이러한 결 과를 바탕으로 청소년의 건강한 식습관 관리를 위해서는 실효성 있는 영양 및 식이교육 프로그램 제공과 정서적 지지가 필요하며, 가족 구성원을 교육 대상에 포함시키는 등 다각적이고 체계적인 대책마련이 필요 하다.

This study examined the quality characteristics and antioxidant properties of fruit and vegetable jellies mixed with Boswellia. Jellies were prepared with 0, 2, 4, 6, and 8% Boswellia, sugar and konjac. As a result, the pH of Boswellia jellies decreased to 5.19, 5.05, 4.94, and 4.84, respectively (p<0.001). Their L-value, a-value, b-value, and hardness increased significantly with increasing levels of added Boswellia (p<0.001), while individual phenolic compounds increased significantly with increasing levels of added Boswellia. Free sugars and organic acid contents had the highest bw10. The total phenolic compounds had the highest BW5 (112.9 mg TAE/g), BW10 (99.41 mg TAE/ g), and while the ABTS activities showed higher values than the control group. Overall, Boswellia can be used to produce high-quality jelly, which is expected to help develop excellent functional jelly products.

This study analyzed the quality characteristics and antioxidant activity of a mixture of apple and carrot juices with different amounts of beet. The pH of the mixed juice sample group increased as the beet amount increased, and the acidity and soluble solid content tended to decrease. As for the L value, the control group was the highest, the beet addition rate decreased, and the a value and b value showed a decreasing trend. As for dietary fiber, B0.1 was found to have the highest dietary fiber content at 0.20 mg/L. As for the mineral, Zn, Fe, and Ca had the highest control group, Mn, Mg, and K had the highest B0.5, and Na and P had the highest B0.1 and B0.3 juices, respectively. Compared to the control group, free sugars increased sucrose as the beet juice added increased. DPPH radical scavenging and total phenol content significantly increased DPPH scavenging as the beet added increased. Therefore, it was found that B0.3 was the most suitable when manufacturing apple and carrot mixed juice with different amounts of beet added, and it is considered as a manufacturing optimization method to improve the marketability and functionality of the product.

This study provides step-by-step suggestions for expanding the foundation of Korean language education and the systematic teaching and learning of the Korean language in New Northern Policy countries. To this end, a literature review was undertaken to explore the existing knowledge in the field, and surveys and online interviews were conducted with local experts. According to the surveys, the New Northern Policy countries were highly accepting of multilingualism and multiculturalism, currently using the Common European Framework of Reference for Languages (CEFR) to accommodate the global standard education model and seeking to strengthen English education in accordance with the de-Russian trend. Also based on CEFR, achievement standards are systematically presented. Korean language education is divided into curricular and extra-curricular, with the Korean language curriculum further subdivided according to the development of the Korean language curriculum. The extra-curricular stream is mainly conducted in after-school programs. The proposed development phase of the Korean pro-language curriculum should establish a reference system including goals and grades that connects with the CEFR. Moreover, to develop the Korean language curriculum further, it is necessary to establish and analyze the Korean language profiles of Korean learners.

The number of aged bridges is increasing so that bridges over 30 years old account for about 11% of all bridges. Consequently, the development of a seismic performance evaluation method that considers the effects of ageing is essential for a seismic retrofitting process for improvement of the seismic safety of existing old bridges. Assessment of the damage situation of bridges after the recent earthquakes in Korea has been limited to the bearings, anchor, and concrete mortar on piers. The purpose of this study is to evaluate the seismic responses of PSC box girder bridges by considering the ageing effect of rubber bearings (RBs) and lead-rubber bearings (LRBs). The modification factor proposed by AASHTO is used to take into account the ageing effect in the bearings. PSC box girder bridges with RBs and LRBs were 3D modeled and analyzed with the OpenSEES program. In order to evaluate the ageing effect of RBs and LRBs, 40 near fault and 40 far field records were used as the input earthquakes. When considering the effect of ageing, the displacement responses and shear forces of bridge bearings (RBs and LRBs) were found to increase mostly under the analytical conditions. It was shown that the effect of ageing is greater in the case of RBs than in the case of LRBs.

전자상거래는 인터넷매체를 통한 비대면적 거래이며, 사업자와 소비자 사이의 거리를 불문한다는 점에서 소비자거래 또한 국내에 국한되지 않는다. 따라서 국제소비자거래가 증가함에 따라 이에 따른 분쟁 또한 증가하고 있는 것으로 보인다. 본 논문에서는 소비자보호적 측면에서 전자거래에 관하여 전자거래기본법과 전자상거래소비자보호법의 미비점을 살펴보기 위하여 그 비교법적 대상으로 국제거래로 이루어지는 전자거래에 법적 장애를 제거하기 위해 마련된 통일적인 규범인 UN전자계약협약으로 하였다. 그리고 전자거래계약의 체결의 과정에 따라서 문제가 발생할 수 있는 정보제공, 청약과 청약의 유인, 오류의 방지, 성립시기와 장소의 문제를 중심으로 살펴보았다. 청약과 청약의 유인과 관련하여, UN전자계약협약이나 전자상거래소비자보호법이나 유사한 관점을 보인다. 그러나 청약과 청약의 유인의 구분에 관하여 많은 논란이 있었던 만큼, 분명히 명시하는 것을 고려해 보아야겠다. 다음으로 송신시기와 관련해서는 UN전자계약협약과 전자거래기본법이 다른 입장 차이를 보이고 있다. 이러한 송신시기와 관련하여 다른 나라의 입장과의 통일적인 관점에서 규율하는 것이 증가하는 국제거래에서 필요하다고 보인다. 마지막으로 장소와 관련하여 UN전자계약협약은 영업소라는 개념을 도입하고 있다. 전자거래에서 장소의 개념은 분쟁발생시 재판관할을 확정하는 등 중요한 문제이다. 그러나 전자상거래소비자보호법과 전자거래 기본법은 영업소가 2이상인 경우에만 주된 관리가 이루어진 곳을 영업소(place of business)로 본다고 명시하고 있지만, 그렇지 않은 경우에는 무엇을 기준으로 하여 영업소를 파악할 것인가의 명시는 없다. 따라서 전자계약협약과 같은 영업소의 실질적으로 파악하는 개념의 명시의 도입은 고려해 볼 필요가 있다.
