In this paper, we present the results of research on the reconstruction of ancient routes of ancient civilization exchange that were once present in the North Jeolla region, which was undertaken by adopting a convergent approach to develop 'Silkroadpia', which is an online platform for the curation and sharing of archaeological and historical spatial data, and 'MEPTA(Multiple Evidence Based Path and Territory Finding Algorithm)'. The results of the research make it possible to reconsider the region's historical identity and its important role in facilitating cultural exchange on the Korean Peninsula and in East Asia. The results can also be used to provide the theoretical basis for the government's land planning policies and for the production of cultural contents that can be used for local regeneration. The ancient route associated with the Baekje Restoration Movement, that took place after the fall of Sabi in 660 CE, was the case study examined in this paper, which discusses the academic value of reconstructing the ancient route, as well as its future use in providing cultural contents.

We propose an practical embodiment-based programming training course for middle school students using Arduino and conduct survey before and after the curriculum. Arduino is an open source physical computing platform that integrates the IDE used in processing language. It is a low-cost, relatively simple I/O interface compared to other platforms, and because of its practical formability, it is educational material suitable for programming. Subsequent surveys will provide feedback on changes in cognition of programming needs and improvement in thinking skills. In this study, the program based on embody-based programming using Arduino was conducted for 8 weeks for each first grade, and 112 middle school students for two years from '16 to '17. Based on the theoretical and practical training, the training was based on the application of the ultrasonic sensor to the RC car and the preparation of the adduction quadrotor drone. The purpose of this study is to prove that the recognition, necessity, and programming education of middle school students are effective for the improvement of thinking ability through the program based on embody-based programming using Arduino.

Existing studies have used a variety of terms related to North Korea's income guarantees, causing some confusion. It can be said that it is a problem that appears only when dealing with the contents of a specific statute in an existing study. To this end, we will look at the laws and regulations related to income security by period and analyze the contents of dictionaries that are also the explanations of the laws and the status of orders and rules. As a result of the analysis, living subsidies are classified into subsidies under the national social insurance system and pension and subsidy under the national social security system. Among them, the pension under the national social security system, which is an income security system for non-workers, includes old age pensions, labor capacity loss pension(general work ability loss pension, accidental work ability loss pension, honored soldiers' work ability loss pension), and survivor pension(general survivor pension, war deads' survivor pension, victims' survivor pension). In particular, it was confirmed that the terminology for social security pension, which has been confusing in previous studies, is a collective jargon for all pensions under the national social security system. This study is significant in that it synthesized the historical transition process of the terminology of income security from the 10th Platform for the National Liberation Society in 1936 to the Socialist Constitution of the Democratic People's Republic of Korea in 2013.

A helideck is one of the essential structures in offshore platforms for the transportation of goods and operating personnel between land and offshore sites. As such, it should be carefully designed and installed for the safety of the offshore platform. In this study, a structural design optimization method for a lightweight offshore helideck is developed based on a genetic algorithm and an attainable design set concept. A helideck consists of several types of structural members such as plates, girders, stiffeners, trusses, and support elements, and the dimensions of these members are typically pre-defined by manufacturers. Therefore, design sets are defined by collecting the standard section data for these members from the American Institute of Steel Construction (AISC), and integer section labels are assigned as design variables in the genetic algorithm. The objective is to minimize the total weight of the offshore helideck while satisfying the maximum allowable stress criterion under various loading conditions including self-weight, wind direction, landing position, and landing condition. In addition, the unity check process is also utilized for additional verification of structural safety against buckling failure of the helideck.

Considering the advent of the Fourth Industrial Revolution, this study examines the changes and influences of intelligent information technology and the role of consumer education in the context of consumption life. The purpose of this study is to provide a theoretical foundation to effectively respond to the future consumption society as an independent consumer by enhancing the understanding of the Fourth Industrial Revolution in terms of consumption life. First, in terms of changes in the consumption paradigm in the Fourth Industrial Revolution, production and consumption are converged by being shared through a comprehensive connection platform in real time. Regarding the meaning of consumption, mental experience is being emphasized; moreover, usage and sharing, rather than ownership, are being highlighted. In terms of major changes in consumption life, the emergence of a more convenient smart consumption life and the possibility of personalized consumption optimized for individual demand are anticipated. Moreover, sustainable eco-friendly consumption is expected to increase further, and rapidly changing consumption trends will experience accelerated progress in consumer-centered changes. Next, the predicted problems in consumption life in the Fourth Industrial Revolution include unequal consumption due to intelligent information technology power center and the use and management of personal information data. Furthermore, ethical concerns related to the introduction of new technologies will become prominent, eventually resulting in issues concerning consumption satisfaction. To effectively respond to these new paradigm changes, consumer education should be value-centered. Ethical aspects of consumption should be considered, and consumption life should include trust and mutual cooperation. Furthermore, consumer education should facilitate creative convergence.

This paper discovers the energy loss factors through the insulation diagnosis of houses or buildings, and proposes directions for energy efficiency improvement. The energy efficiency factor of a building consists of insulation diagnosis, thermal bridge diagnosis, window diagnosis, airtight diagnosis, and equipment diagnosis. Among the residents and facilities in the energy welfare blind spot, an energy efficiency diagnosis was conducted for one senior citizen building located in Naju-si, Jeollanam-do, and energy efficiency diagnosis was conducted after insulation was installed. Energy measurement, diagnosis and analysis were performed using the IoT-based integrated wired/wireless energy diagnosis platform, Energy Finder. As a result of comparison, an overall energy saving rate of 16.38% was achieved. Annual heating energy consumption per unit area decreased from 333.51kWh before construction to 277.35kWh after construction, and annual cooling energy consumption per unit area decreased from 5.51kWh before construction to 5.22kWh after construction. The annual primary energy consumption per unit area decreased from 464.52kWh before construction to 403.69kWh after construction, and the annual energy cost was reduced from 3,063,307.14 won before construction to 2,641,072.49 won after construction. The additional improvement work is needed on the standards affecting energy efficiency other than insulation.
