Recently, the environment has been recognized as an important factor in increasing competitiveness in the industry. In agriculture and rural areas, the environment is becoming important in terms of the competitive advantage of agricultural products and continued regional development. This study intended to provide farmers with basic data for the continuous development of local agriculture through exploratory studies of environmental behaviors and regional development. In this study, 107 questionnaires were used for analysis of farmers in Jinan County to analyze the impact of farmers' environmental consciousness on regional development, and the research model was verified using a structural equation model. As a result of the analysis, it was analyzed that among the components of the environmental consciousness of farmers, environmental health has a statistically significant positive effect on environmental behaviors, while environmental interest and soil environment do not have an impact. The environmental behaviors of farmers have not been shown to be statistically significant to regional development. As a result of the analysis of this research, first, it is necessary to foster at the local level by establishing a customized fostering system for each village and region, such as education and technical support to vitalize the participation of young farmers and small and medium-sized farmers through the establishment of an Eco-friendly agricultural organization support system. It is necessary to raise public awareness of the public good function of agriculture and expand opportunities for sharing the value of Eco-friendly agriculture.

Recently, owing to the high demand for eco-friendly cars in the automotive industry, noise and vibrations have become major challenges. The use of laminated damping steel is increasing in response to these demands. Laminated damping steel is primarily used in sound insulation plates. The vibration energy is converted into thermal energy due to the viscoelastic resin being located between two steel sheets and being able to damp the vibrations when an external force, such as, noise or vibration is applied to the steel plate. Laminated damping steel is chiefly applied to dash panels in automotive body parts, and because of its structure, junction technology for bonding with other components is necessary. However, there has not been sufficient research conducted on junctions. In this study, regardless of the electrode shape, in the range of 4.0 ~ 8.0 kA welding current, the same welding force and welding time were applied which were 2.8 kN and 200 m/s (12 cycles) and the tensile shear load and nugget size were analyzed after the resistance spot welding between different materials of laminated damping steel with a thickness of 1.035 mm. The results show that in the range of 5 ~ 8 kA welding current, 1.035 mm laminated damping steel meets the MS181-15 standard, which is the technical standard of Hyundai-Kia Motors.

The goal of the study is to examine and assess how the factors of logistics service quality provided by logistics service providers influence customer loyalty and satisfaction in Vietnam. This study employs samples of the Kansei technique. The article's data was gathered through an online survey of 388 distinct Vietnamese customers who used logistics services before and during the Covid-19 outbreak. After the data was obtained, it was evaluated using SmartPLS 3.0's Cronbach's Alpha test and structural equation model (SEM). Staff service quality, operational service quality, and technical service quality are the three factors that determine the quality of logistics services in the study. Out of the 10 proposed hypotheses, research findings show that five are acceptable. The Covid-19 Pandemic in Vietnam had a significant impact on all dimensions, but it had no effect on how satisfied customers were with the logistics service providers. Nevertheless, loyalty is considerably influenced by only one factor, which is customer satisfaction, and customer trust moderates the relationship between these two factors. As a consequence of that, several managerial implications have been proposed to help logistics service providers improve their services to attract and keep Vietnamese customers using their service in the long term.

Metaverse is a digitally generated world beyond the physical realm; many fashion brands are launching virtual stores in Metaverse. This study explores the cases of flagship stores of fashion brands in Metaverse to understand the peculiarity of Metaverse retailing. This study selected four flagship stores of fashion brands launched on ZEPETO, the largest Metaverse platform in Korea. The characteristics of Metaverse retailing used for case analysis were store (store credibility, servicescape, ease of use), product (content, demos, incentives), social factor (store personnel, store customers), and entertainment (events, games, free gifts). The results illustrate that a transaction system linked to reality could not be established due to technical limitations; it was difficult to obtain specific product information, such as the color, size, and fabric. However, all four fashion brands overwhelmed the traditional retail channels in terms of providing various spatial experiences by operating their virtual stores in global cities related to the heritage and identity of each brand. Furthermore, fashion brands can convey a sense of deviation and fantasy to consumers by delivering unique entertainment activities in Metaverse that they cannot easily provide in real life.

The article deals with issues related to the tradition of carpet production on the territory of Kazakhstan where, for the most part, tribes engaged in nomadic livestock raising lived. Analyzing the technological component of this traditional craft, the author focuses on the main factor that influenced carpet weaving along with arts and crafts-the nomadic method of production of the Kazakhs. The study of the ideological component that accompanies the process of making various types of carpets allows us to conclude that it has a sacred meaning and subordination to myth, rite, and ritual. At the mythmaking level, the process of making carpets, like any other activity among nomads, personified the process of creating the world, the marriage of Kok-Tengri (Heaven) and Zher-Su (Earth), and the creation of the Cosmos from Chaos. The process of carpet weaving, as well as the process of making felt, symbolized the act of creation, the marriage of Heaven and Earth, and male and female principles. The study of various types of ornaments that Kazakhs and their ancestors used to decorate carpets allows us to conclude that the ornament applied to carpet products was the bearer of the most valuable information about the mythological worldview of the people. Carpets in their structure reproduced the structure of the Universe, which has a binary, ternary, and quaternary system. The ornament has turned into a kind of coded text, reflecting ideas about the cosmogonic structure of the Universe and an awareness of the harmony of the world. The location of Kazakhstan on the northern routes of the Sogdian Road (Great Silk Road) allowed the spread of various ideas, due to which carpet weaving was influenced by other peoples in technical and stylistic design.

In the l950s, under the legacy of traditional agriculture, Ascaris lumbricoides, spread epidemically in the war-bitten society of Korea. Consensus on the parasite control was drafted in the Parasite Disease Prevention Act, which passed a parliamentary agreement in 1966, and established safe disposal of feces and mass chemotherapy as control strategies. Biannual stool examinations and treating infected schoolchildren were basic scheme of the control activity through which revenue could be secured for organized business. In the 27 years following 1969, a maximum of 16 million stool examinations had been done every year. Cellophane thick smear enabled the task. The infection declined remarkably in the 1970s when industrialization and green revolution proceeded. A population study of A. lumbricoides in the late 1970s helped us better understand its epidemiology. The data also settled down the understandable protest of teachers against the repeated stool examinations. In the 9 years following 1987, the target population was gradually reduced when the egg positive rate was below 0.1%. An article in the Korean Law, stipulating obligatory stool examinations, was made optional. Although the long-term Korean effort of Ascaris control was a success, the effect of mass chemotherapy was not as succinct in terms of lowering reinfection. In the period of control, Korean agricultural technology changed, and the economy grew and supplied sanitary facilities by which the vicious cycle was disconnected. Reduction of morbidity was a benefit of mass chemotherapy, which is the only control method feasible in economically difficult countries. The most important hurdle of parasite control in the 1960s was poverty of general population and limited financial resources in Korea but the society formed a consensus on the priority of intestinal helminthiasis control during the ordeal period. The national consensus in the 1960s was the critical milestone for Ascaris control in Korea. Under the social agreement, application of timely technical and research advancements in parasitology achieved the success of ascariasis elimination. The successful experience of ascariasis elimination in Korea can be a benchmark for countries where neglected tropical diseases are endemically recycled.

The need for off-site construction has increased in the construction industry in Korea in recent years due to the enforcement of the 52-hour workweek, the increasing age of workers on construction sites, the deepening dependence on overseas workers, and the stagnation of productivity in the construction industry. Thus, studies on OSC started in April 2020. In addition, as a national policy study advocating the modular construction method, which is one of the OSC methods, was completed in the first half of 2019. 70 housing units in two complexes that satisfied the Housing Act requirements have been supplied to citizens. However, although modular construction methods have been recognized as a dramatic construction method that achieves shortened construction schedules and solves the issues of cost reduction and the shortage of technical workers on sites by combining the advantages of the manufacturing industry and applying the economies of scale, realistically it has issues due to the rising cost of steel and a low pre-fabrication ratio. Moreover, the construction time of core parts, such as those built by pouring concrete, has become a factor that hinders the shortening of construction times. Thus, this study aims to propose a precast concrete(PC) modular construction system, which fuses three-dimensional infill as an interior finish material and a three-surface PC module that can acts as a structure for a construction method that is economical and can shorten construction time.

Recently, fan out wafer level packaging, which enables high integration, miniaturization, and low cost, is being rapidly applied in the semiconductor industry. In particular, FOWLP is attracting attention in the mobile and Internet of Things fields, and is recognized as a core technology that will lead to technological advancements such as 5G, self-driving cars, and artificial intelligence in the future. However, as chip density and package size within the package increase, FOWLP warpage is emerging as a major problem. These problems have a direct impact on the reliability and electrical performance of semiconductor products, and in particular, cause defects such as vacuum leakage in the manufacturing process or lack of focus in the photolithography process, so technical demands for solving them are increasing. In this paper, warpage simulation according to the thickness of FOWLP material was performed using finite element analysis. The thickness range was based on the history of similar packages, and as a factor causing warpage, the curing temperature of the materials undergoing the curing process was applied and the difference in deformation due to the difference in thermal expansion coefficient between materials was used. At this time, the stacking order was reflected to reproduce warpage behavior similar to reality. After performing finite element analysis, the influence of each variable on causing warpage was defined, and based on this, it was confirmed that warpage was controlled as intended through design modifications.

북극 해빙의 급속한 용해는 유럽과 아시아 사이의 실행 가능한 대체 해로로서 북극항로에 대한 관심을 증대시켜 왔다. 현재까지 북극항로의 기술적 실현 가능성, 안전성, 수익성, 환경 영향 등을 고려한 광범위한 연구가 진행되어 왔다. 북극항로는 국제 교역의 중요한 루트가 될 것이며, 무역 원활화를 위해서는 항만 효율성이 무엇보다 중요하다. 그럼에도 불구하고 북극항로의 중요한 위치해 있는 항만들, 특히 러시아 북극 항만들의 효율성 평가에 대한 연구가 제한적인 상황이다. 따라서 본 연구는 데이터 포락 분석(DEA) 모델과 Malmquist 생산성 지수를 적용하여 러시아 17개 항구의 운영 현황을 분석하고, 효율성을 평가하고자 한다. DEA 분석 결과, 주로 서부 지역에 속하는 항만들의 효율성이 높게 나타났으며, 특히 무르만스크와 바란데이와 같은 항구는 지속적으로 높은 효율성과 꾸준한 규모의 수익을 보여주고 있음이 규명되었다. DEA-Malmquist 모형 결과에 의하면 기술발전에도 불구하고 모든 항구에 대한 전반적인 자원 활용 효율성의 개선 정도가 상대적으로 적은 것으로 나타났다. 본 연구의 결과는 인프라 개발 계획 및 관련 정책 수립을 위한 기초자료를 제공하고, 북극항로 항만 당국에 실질적인 시사점을 제공한다.
