The purpose of this study is to examine the effects of agriculture on the career adaptation and career decision by measuring the job value and the subjective norm of agriculture. Conclusions based on the study results can be suggested as follows. First, career decision self-efficacy and subjective norm were significant variables in career adaptability of agriculture major college students. Therefore, the belief that one can plan and practice career goals and the affirmation of career plans and decisions in the vicinity are important factors in career adaptability. Second, Self-Realization and social recognition were significant variables in career decision self-efficacy of college students majoring in agriculture. In other words, it can be judged that social recognition such as honor and honor of others in a career choice has a positive effect on the career decision self-efficacy which is self-esteem in career selection. Lastly, An important variable for the subjective norms of agricultural college students was social recognition. This can be said that the positive perception of the surrounding people is very important as the value of social recognition is more important.

This research investigated variations of the engine performance and the exhaust emission characteristic of a direct injection diesel engine by fueling a commercial diesel fuel, which was blended with the di-ether group (butyl-ether: BE). The smoke emission reduced to 26% from the diesel engine with the blending fuel (diesel fuel 80 vol-% + BE 20 vol-%)at the full engine load of 2500 rpm compared to it with the diesel fuel only. The power, torque and brake specific energy consumption of the diesel engine showed very slight differences. The NOx emission from the diesel engine, however, with the blended fuel was higher than with the commercial diesel fuel only. By applying EGR method, as a counter plan of the NOx reduction, this research obtained reductions of the smoke and NOx emission at the same time from the diesel engine with the BE blended diesel fuel.

This study examined changes in dietary life and dietary life satisfaction in one-person households during the COVID-19 pandemic. Using a sample of 916 one-person households from the Food Consumption Behavior Survey, we applied ANOVA and a system of equations model for our analysis which produced four main results. Firstly, during the COVID-19 pandemic, eating homemade and delivered meals increased, whereas eating restaurant, group, and HMR meals decreased. Eating breakfast and regular eating habits also increased during the pandemic. Secondly, approximately 30% of the sample reported increased expenditure on fresh food and HMR meals. The proportion of positive changes in dietary life was also greater than negative changes, and dietary life satisfaction was about three times higher than it had been before the pandemic. Thirdly, having breakfast and regular eating fully mediated the relationship between spending on fresh food and dietary life satisfaction, as well as the relationship between HMR purchases and dietary life satisfaction. Changes in expenditure on fresh food and HMR meals positively affected dietary life satisfaction through eating breakfast and regular eating. Fourthly, increased consumption of delivered food had a positive direct effect on dietary life satisfaction. Among sociodemographic variables, gender, education, occupation, and age were also significantly related to changes in dietary life satisfaction.

The production of multipurpose cotton fabrics aimed at elevating the quality of aerobic and dance sportswear is explored in this study. Powder metallurgy, known for its high efficiency in manufacturing technological components with minimal waste, is employed as a method for fabricating brush ferrules for painting. The utilization of iron-copper material, prepared through powder metallurgy, enhances the strength and quality of the brush ferrules. A microscopic analysis reveals a robust interconnection between the particles of each layer achieved through isostatic pressure, resulting in a favorable microstructure. The relative density and strength of parts produced from copper-iron powder exhibit an increase with higher pressure levels. The application of this material in brush ferrules ensures their durability and longevity, thereby supporting the creation of artwork. The evolution of art over time reflects changing ideas and possibilities, and technological advancements have significantly improved artistic tools. The role of tools in artistic expression is paramount, and the integration of powder metallurgy materials in brush ferrules fortifies their artistic importance. In summary, this study underscores the advantages of powder metallurgy in augmenting the quality of art tools and facilitating artistic creation.

There is a lot of evidence of early port cities and small habitation sites along the Thai-Malay Peninsula's coastlines. These sites appeared on the trans-peninsular routes during the Maritime Silk Roads period, from 2,000 to 1,500 BP. The Thai-Malay Peninsula was mentioned in many documents as Suvarnabhumi (India), Aurea Chersonese (Greek), and Jin Lin (Chinese), meaning the Golden Land. Ptolemy's map displays that there were many port cities along this peninsula. It corresponds to the Milinda-panha, which depicts many port cities in Suvarnabhumi. Foreign documents primarily documented the presence of major port cities, while inland habitation sites received less recognition. This paper aims to reconstruct the trans-peninsular routes in order to understand their networks, connections, and roles. The second aim is to understand the hierarchy of each site. This paper will focus on two important settlements and high-value artifacts along three routes: the Kra Isthmus Route, the Pho Khao Thong and Tha Chana Route, and the Krabi to Surat Thani Route. I conducted an archaeological survey of these three routes and others during 2021-2023 under the Suvarnabhumi Studies Center, TASSHA Institute, and the Ministry of Higher Education, Science, Research, and Innovation.

한국은 코로나19로 인한 감염전파를 줄이기 위해 4단계의 사회적 거리두기 기준을 설정하고 확진자 발생 비율을 기준으로 단계를 전환하여 시행하고 있다. 이러한 사회적 거리두기는 사람들의 이동 및 모임 등 사회적 접촉을 제한함으로써 시민들의 활동량에 변화를 가져왔다. 이를 직관적으로 확인할 수 있는 데이터 중 하나가 Night Time Light (NTL)이다. NTL은 인공위성에 포착된 불빛을 활용해 측정한 국가경제규모를 측정할 수 있는 변수로, 야간동안 사람의 사회 활동을 파악하는데 활용할 수 있다. NTL 자료는 수오미 위성(Suomi National Polar-orbiting Partnership, S-NPP)에 탑재된 센서인 Visible Infrared Imaging Radiometer Suite (VIIRS)에 포함된 Day-Night Band (DNB)를 통해 얻을 수 있다. 본 연구는 2019년 1월 5일부터 2021년 10월 26일까지 1023개의 Suomi 자료를 수집하고, 서울의 NTL 변화를 시계열로 생성하여 사회적 거리두기 단계와의 상관관계를 분석하였다. 그 결과 사회적 거리두기의 단계가 높아질수록 NTL의 공간적, 시간적 변화가 모두 감소된 것으로 나타났다. 이는 더 높은 단계의 사회적 거리두기 정책이 실행됨에 따라 야간 시간대의 상업 활동 및 모임 인원제한 등과 같은 사회적 활동의 제한이 실제로 서울의 NTL 감소에 영향을 준 것으로 해석할 수 있다. 본 연구는 향후 코로나19 관련 정부의 정책을 평가하고 개선하기 위한 참고자료로 활용할 수 있을 것이다.
