Diffusion of non-professional flower growing in Korea still lags behind. The objectives of the study are to establish a theoretical modes to explain the diffusion of social floriculture, to identify some characteristics and problems of growing flower crops to cultivate amenities and emotions, and to suggest remedial measures for fostering it. Theoretical model adopted in this study consists of such variables as education, social movement, policies, diffusion of social flower growing, amenities, and emotional cultivation. For identifying the diffusion characteristics of flower growing, projects implemented by a non-governmental organization, schools, local and central government organizations were analyzed. In order to stimulate the diffusion of social flower growing and to increase its effects, there needs to strengthen education of stakeholders, establishment of partnership among schools, non-governmental and governmental organizations, and institutional supports including manpower and finances. Linking flower growing projects to community festival and tourism development programs can foster institutionalization of community flower growing. Furthermore, the introduction of wild, symbolic and traditional flowers and trees will help to specialize and improve community landscapes.

Currently, many universities are implementing software-oriented universities and artificial intelligence-oriented universities to foster software-oriented manpower. We are educating students to design and produce computational thinking and coding directly with their major knowledge. However, computer education is not easy for non-majors, and there are many difficulties in coding. The results of responses from 104 students from the College of Health Sciences and College of Social Management who took the liberal arts computer at University H were analyzed using SPSS 26.0 version. In the liberal arts computer class for non-majors, a PJBL-based class plan was proposed. The effectiveness of PJBL-based classes was confirmed through a questionnaire for the improvement of artificial intelligence liberal arts courses. As a result, PJBL-based education showed statistically significant results in terms of satisfaction, effectiveness, and self-efficiency of classes regardless of major.

This study aims to enhance the engineering education for non-majors by incorporating the concept of Global Citizenship Education and addressing the need for education that responds to climate and ecological changes. The study uses robot programming as a tool to foster the development of global citizens. Non-majors often struggle with producing more than just motionless forms or solid productions, due to a lack of understanding of mechanisms and coding. The study proposes the use of the Convergence D-SteamRobot (DSR) to address this issue by blending humanities and engineering. This is achieved by presenting problems through books to increase empathy, integrating simple machine mechanisms, and creating prototypes to solve self-defined problems. Through this process, learners determine the SDGs topic they want to solve and learn about the simple mechanical mechanism involved in producing the prototype. The educational model provides a constructivist learning environment that emphasizes empathy and exploration, encourages peer-learning, and improves divergent thinking and problem-solving skills.

To overcome current hardship during recent years of university reform, statistics departments of Korean universities should form a new shape with efficient strategies: First, they should value interdisciplinary and open education to foster scientific generalists rather than specialists (Bode.Mosteller.Tukey.Winsor, 1949). Second, they should work out on developing curriculum and improving educational quality for non-statistics majors (Ahn.Cho.Huh, 1994). The service market is widely open and its value is certainly worthy. Third, they may change their department name from "statistics", of which the social image is not quite right, to "data science" or "data information". Statistics is a field of learning on data methodology (Friedman, 1997). methodology (Friedman, 1997).

This study was carried out to improve a technique of cloned animal prodcution by preactivation of nuclear recipient oocytes with ionomycin and 6-dimethylaminopurine (6-DMAP) in rabbits. The oocytes were collected from the oviduct of superovulated rabbit at 19∼20 hours post hCG injection. The collected oocytes were preactivated and self-enucleated by treating 5 uM ionoycin for 5 min, and 2.0 mM 6-DMAP for two hours. Microsurgical removel of the chromation complex in the second polar bodies was effectively performd and single blastomere separated from 32-cell stage rabbit embryos was injected into the perivitelline space of the enculeated recipient oocyts. Follwoing electrofusion and in vitro culture for 18 hours, the nuclear transplant(NT) embryos were transferred into the uterine horns of naturally mated or synchronized recipient does. When 32 NT embryous reconstituted with preactivated oocytes were transferred to 2 recipient does, one foster doe delivered two offspring (6.3%), while not a offspring was delivered from three foster does which received 17 NT embryos reconstituted with non-preactivated oocytes. A total of 68 NT embryos reconstituted with preactivated oocytes were transferred into the uterine horns of 7 synchronized ecipient does. Among them, two recipients were pregnant and delivered three offspring(5.9%).

The major purpose of this study was to investigate purchasing behavior of environmental products by Korean consumers, which will ultimately help foster sustainable consumption. Environmental consciousness, environmental behaviors, level of awareness of environmental products, and purchasing of environmental products were examined. Mean differences between purchasers and non-purchasers of environmental products were compared in terms of environmental consciousness and behaviors, and the level of awareness of environmental products. A survey was conducted on 310 consumers in the greater Seoul metropolitan area. The data were analyzed by frequencies, percentages, logistic regression, and t-tests using a variable for interval scale and a variable for nominal scale. There were significant mean differences between purchasers and non-purchasers of environmental products on three variables of environmental consciousness and behaviors. Those who were educated on environmental issues showed a higher preference in purchasing environmental products. Among socio-demographic variables, the income level was the only variable that showed a significant mean difference between the two groups. Also, there was a remarkable difference in purchasing behavior between the two groups. For the purchasers of environmental products, the purchasing decisions took into account environment-friendliness of products. Non-purchasers of environmental products put more emphasis on price or quality of products. The results of the logistic regression analysis indicated that those who had higher education, who viewed environmental pollution as a serious problem, and who are more cognizant of the environmental labeling tend to purchase more environmental products.

An antenna arrays for a satellite navigation systems require more antenna elements to mitigate multiple jamming signals. In order to maintain the small array size while increasing the number of antenna elements, miniaturization technique is essential for antenna design. In this work, an electrically small circular microstrip patch antenna with a 3 dB hybrid coupler is designed as an element antenna, where the 3 dB hybrid coupler can yield the circularly polarized radiation characteristic. The miniaturized element antenna typically has too large capacitance in GPS L1 and GLONASS G1 bands, making it difficult to match with a single stand-alone non-Foster matching circuit (NFMC) in a stable state. Therefore, we propose a new matching technique, referred to as the hybrid matching method, which consists of a NFMC and a passive circuit. This passive tuning circuit manages reactance of antenna elements at an appropriate capacitance without a pole in the operating frequency range. The antenna array is fabricated, and the measured results show a reflection coefficient of less than -10 dB and an isolation of greater than 50 dB. In addition, peak gain of the proposed antenna is increased by 22.3 dB compared to the antenna without the hybrid matching network.

Blockchain technology has paved the way for the rise of non-fungible tokens(NFTs) in recent years. NFTs enable the unique ownership of digital assets and harness the power of blockchain's transparency and decentralization. However, existing NFT platforms often pose barriers to entry for the public due to their technical complexity and high issuance costs. To address the problem, this paper proposes a user-friendly NFT platform with a simplified issuance process. A home page is created to allow easy NFT issuance for anyone. These advancements are expected to foster the growth of the NFT market and facilitate the development of new business models.

WTO설립과 FTA협정의 증가로 관세는 낮아지고 있으나 무역구제조치와 무역기술장벽(TBT), 위생검역(SPS), 통관규제 등의 비관세조치들이 무역장벽이 되어 자유무역을 제한하고 있다. 수출주도 경제성장을 이룬 우리나라는 증가하는 비관세조치들에 대하여 대응방안을 제시하여야 한다. 비관세조치들은 복잡하고 국가마다 적용되는 것이 다르므로 유형별, 산업별, 국가별로 맞춤형 대응방안을 제시하여야한다. 이를 위해 비관세조치DB를 구축하여야한다. 이런 비관세조치들을 수집하고 분석하여 대응방안을 제시하기 위해서는 정부 산하의 전담조직이 반드시 필요하다. 그리고 비관세조치에 대한 상대국 간의 협의 등과 WTO위원회에서 활동이 중요하다. 또한 비관세조치에 관한 역량과 전문성을 가진 전문 인력 양성이 필요하다. 기존의 연구가 각 국가의 비관세조치현황을 토대로 한 연구나 국제기구의 보고서 등을 통하여 분석하였기 때문에 조치유형의 식별과 국가 간 비교분석에 한계가 있었다. 그러므로 본고는 규제의 식별과 국가 간 비교가 가능한 WTO I-TIP의 비관세조치DB를 바탕으로 분석하였다.

Objectives: The Indonesian government issued large-scale social restrictions (called Pembatasan Sosial Berskala Besar, or PSBB) at the beginning of the coronavirus disease 2019 (COVID-19) pandemic to control the spread of COVID-19 in Jakarta, Bogor, Depok, Tangerang, and Bekasi (Greater Jakarta). Public compliance poses a challenge when implementing large-scale social restrictions, and various factors have contributed to public non-compliance with the regulation. This study aimed to determine the degree of non-compliance and identify the factors that contributed to public non-compliance with the PSBB in Greater Jakarta, Indonesia. Methods: This was a quantitative study with a cross-sectional design. A total of 839 residents of Greater Jakarta participated in this study. Data were collected online using a Google Form, and convenience sampling was undertaken. Univariate and multivariate analyses were performed to explore the relationships between public non-compliance with the PSBB regulation and socio-demographic variables, respondents' opinion of the PSBB, and social capital. Results: A total of 22.6% of subjects reported participating in activities that did not comply with the PSBB. The variables that most affected non-compliance with the PSBB were age, gender, income, opinion of the PSBB, and social capital. Conclusions: Strengthening social capital and providing information about COVID-19 prevention measures, such as washing one's hands with soap, wearing masks properly, and maintaining social distancing, is essential. Robust public understanding will foster trust and cooperation with regard to COVID-19 prevention efforts and provide a basis for mutual agreement regarding rules/penalties.
