The characteristics of poverty can be comprehensively revealed from the two angles of income and multidimensional. This paper compares China's rural income poverty measure with multidimensional poverty index using data from China Family Panel Studies (CFPS) by focusing on the static and dynamic disparities, and analyzes the factors influencing poverty through the Logit model. The results show that there exists a substantial mismatch in who is deemed poor, 60 percent of multidimensional poverty households are not considered poor in terms of income poverty, and 70 percent of income poverty households are not considered poor in terms of multidimensional poverty; There is a high level of disparity between the dynamics of the two measures of poverty. Among those who rose in the income dimension, only about 7 percent also rose in the multidimensional measure from 2016 to 2018.

끊임없이 발전하는 기술은 4차 산업혁명시대를 열게하는 중심이 되었으며 세상의 모든 것을 변화시켜가고 있다. 최근에는 혁신적이고 고도화된 IT 기술이 완전히 다른 분야와 유기적으로 융합하여 새로운 가치를 만들어 가고 있다. 특히 패션 분야에서는 이와 같은 선도적인 기술을 바탕으로 패션, 그 이상의 기능을 담당하는 '스마트패션'의 시대를 맞이하고 있다. 패션에서의 새로운 산업 분야로 자리매김하고 있는 스마트패션에 대한 사용자의 요구가 증대하고 새로운 제품을 출시하고자 하는 기업의 시도가 계속되고 있으나 학교 현장에서는 이에 대한 적절한 교육과정이 부재한 상태이다. 특히 IT 엔지니어와 패션 디자이너와의 협업의 경험이 전무할뿐만 아니라 제품을 설계하고 제작해 나가는 과정에 대한 개념이 서로 완전히 상이하여 융합의 시도가 단지 시도로 그치고 있는 실정이다. 이에 본 연구에서는 IT와 패션 전공 학생들이 함께 참여할 수 있는 융합 교과 과정을 설계함으로써 미래의 산업사회 요구에 선제적으로 대응하고자 한다. 이를 통해 상이한 전공을 가지고 있는 두 전공 학생들에게 타 전공에 대한 지식을 이해할 수 있는 기회를 제공하는 동시에 융합에 대한 경험을 충분히 제공함으로써 미래 시장으로의 선도 진입과 역할 수행의 적합성을 이루어 낼 수 있도록 한다.

Jeju Haenyeo is in danger of extinction, and the issue of labor force reproduction is emerging as an important agenda. The traditional method of labor force reproduction based on matrilineal succession is gradually disappearing, and part of its role is being taken over by vocational training institutions such as Jeju Haenyeo School. In order to maintain the social, economic, and cultural sustainability of Jeju Haenyeo, sustainable labor reproduction is an essential prerequisite, so multidimensional study on the labor reproduction issue of Jeju Haenyeo has important academic and policy implications. Accordingly, we analyzed previous studies directly and indirectly related to the reproduction of Jeju Haenyeo's labor force and the role of vocational training institutions in labor force reproduction. Based on this, we presented three issues that should be addressed. First, a detailed analysis of the role of Jeju Haenyeo School as a key platform for reproducing the Jeju Haenyeo's labor is required. Second, it is important to pay attention to the role of social capital in the reproduction of the Jeju Haenyeo labor. Third, a qualitative analysis process is needed to understand the meaning of the experiences in order to measure the organic relationships centered on the haenyeo community.

The 5 Game changer means the concepts of the army's operation against the enemy's asymmetric threats so that minimize damage to the public and leads to victory in war in the shortest time. A study of network architecture of Dronebot operation is a key study to carry out integrated operation with integrated C4I system by organically linking several drones battle groups through ICT. The NBC reconnaissance drones can be used instead of vehicles and humans to detect NBC materials and share situations quickly. However, there is still a lack of research on the swarm flight of the NBC reconnaissance drones and the weaknesses of cyber electronic warfare. In this study, we present weaknesses and countermeasures of CBRNs in swarm flight operations and provide a basis for future research.

This study evaluated the perception, school stress, psychological factors, and association of students in middle and high school groups in terms of their BMI (Body Mass Index). The '2010 Korea Youth Health Survey 'was used to study data 7187 people. The subjects were classified into the underweight group (BMI < 20), normal group (BMI 20 - 24), overweight group (BMI of 25-29), and obese group (BMI of 30 or higher). The subjects found to have experienced smoking were as follows: underweight BMI group (17.2%), normal weight group (18.4%), overweight group (21.8%), and obese group (25.8%) (p=0.016). The level of satisfaction was as follows: $14.24{\pm}3.15$ for the normal weight group, $13.67{\pm}3.13$ for the overweight, and $12.84{\pm}3.72$ in the obese group. The normal-weight group had a higher level of satisfaction (p=0.005). Underweight, normal, overweight, and obese BMI group were at school for an average of $33.57{\pm}5.76$, $33.45{\pm}5.50$, $33.12{\pm}5.34$, and $32.21{\pm}7.43$ hours per week, respectively (p=0.044). Therefore, the development of social misfit youths needs to be managed properly and effectively to improve their physical and mental health. Industry, academia and government need to collaborate with programs to achieve this aim.

Research is being conducted on graphene to provide graphene having both excellent physical as well as electrical properties in addition to unique physical properties. In this study, Hummer's method, which is a representative method for chemical exfoliation, was applied in order to investigate the possibility of the mass production of high-quality graphene oxide. Three types of graphite (graphite, crystalline graphite, and expanded graphite) were used in the preparation of graphene oxide with variations in the amount of potassium permanganate added, reaction temperature, and reaction time. Then a Fourier transform infrared spectroscopy (FT-IR), a Raman spectrometer, and a transmission electron microscope (TEM) were used to measure the quality of the prepared graphene oxide. Of the three types of graphite used in this experiment, crystalline graphite showed the highest quality. The prepared graphene oxide was then purified with an organic solvent, and an analysis conducted using energy dispersive X-ray spectroscopy (EDS). From the results of the residual values, we were able to confirm that both acid wastewater and wastewater were best purified using cyclohexane. The method for manufacturing graphene oxide as well as the method of purification using organic solvents that are presented in this study are expected to have less of an environmental impact, making them environmentally friendly. This makes them suitable for use in various industrial fields such as the film industry and for heat dissipation and as coating agents.

The superiority and safety of eco-friendly agricultural products are well-known. The purpose of this study is to provide fundamental data for creating a safe food culture, to improve the quality of school food services, and to increase student satisfaction with school food services. We compared the perception of eco-friendly agricultural products and food service satisfaction between students with and without exposure to a dedicated event for learning about eco-friendly products (an Eco-friendly Food Service Day) in elementary and middle school. When students were asked to define eco-friendly products, "organic products" was a highly frequent response in schools with an Eco-friendly Food Service Day, while "pesticide-free products" was a highly frequent response in school without this event. For most students, a factor in choosing eco-friendly products was a quality certification mark. Students from elementary schools with an Eco-friendly Food Service Day had a higher frequency of using eco-friendly agricultural products at home compared to students from schools without the event (p<0.01). In addition, the satisfaction with school food service was higher in schools with an Eco-friendly Food Service Day (p<0.05). These results suggest it is important to promote the use of superior and safe eco-friendly agricultural products while developing a variety of menus considering students' preferences.

As an alternative of making students active and independent under the passive learning conditions in school math classes, many researchers have paid much attention to problem posing and done a lot of research on it. Above all, Brown and Walter proposed What I f Not strategy as a means of problem posing. In this strategy, during the process of posing problems, the transformation of their attributes is inevitably made, and so after problem posing, the process is finished by explaining the problem. But only the simple transformation of attributes could pose wrong problems. It suggests that it is very important to recognize the relationship which leads to organic connection between attributes in order to pose the right problem. However, many other studies of problem posing haven't focused on this fact. Thus, this study tried to design a model of problem posing to help recognize inherent knowledge in the problem and then pose the right problem by adding an activity of meaning analysis. We concretely showed a model of problem posing emphasizing the analysis of meaning by means of an example, thereby examining the meaning of the model. This study expects students to have the chance to understand the true meaning of problem posing and to be active learners after all.
