Sweet potato (Ipomoea batatas L.) is an essential crop in the Paraguayan diet. It plays a crucial role in food security. It is a source of income for family agriculture. It has a significant potential to adapt to various climatic and soil conditions in Paraguay, making it a promising crop for improving productivity. However, Paraguay faces a deficit in the development of sweet potato cultivation technology, resulting in a low productivity of 5.3 ton/ha. Efforts have been made to collect and characterize sweet potato genotypes, covering a diversity of native varieties. These efforts have laid the groundwork for future sweet potato research and development. Still, ongoing research and development of strategies are needed to address existing challenges of improving genetic resource traits and developing cultivation technology and to fully exploit growth opportunities in this sector. This review summarizes sweet potato cultivation in Paraguay, focusing on several key technical aspects. It analyzes current market situation and production conditions as well as the availability of genetic materials adapted to different ecoregions. Additionally, it explores prospects for the development of advanced sweet potato crops, including the production of high-quality, virus-free sweet potato plants with improved productivity.

In the nuclear fuel cycle (NFC) facilities, the failure of Heating Ventilation and Air Conditioning (HVAC) system starts with minor component failures and can escalate to affecting the entire system, ultimately resulting in radiological consequences to workers. In the field of air-conditioning and refrigerating engineering, the fault detection and diagnosis (FDD) of HVAC systems have been studied since faults occurring in improper routine operations and poor preventive maintenance of HVAC systems result in excessive energy consumption. This paper aims to provide a systematic review of existing FDD methods for HVAC systems therefore explore its potential application in nuclear field. For this goal, typical faults and FDD methods are investigated. The commonly occurring faults of HVAC are identified through various literature including publications from International Energy Agency (IEA) and American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). However, most literature does not explicitly addresses anomalies related to pressure, even though in nuclear facilities, abnormal pressure condition need to be carefully managed, particularly for maintaining radiological contamination differently within each zone. To build simulation model for FDD, the whole-building energy system modeling is needed because HVAC systems are major contributors to the whole building’s energy and thermal comfort, keeping the desired environment for occupants and other purposes. The whole-building energy modeling can be grouped into three categories: physics-based modeling (i.e., white-box models), hybrid modeling (i.e., grey-box models), and data-driven modeling (i.e., black-box models). To create a white-box FDD model, specialized tools such as EnergyPlus for modeling can be used. The EnergyPlus is open source program developed by US-DOE, and features heat balance calculation, enabling the dynamic simulation in transient state by heat balance calculation. The physics based modeling has the advantage of explaining clear cause-and-effect relationships between inputs and outputs based on heat and mass transfer equations, while creating accurate models requires time and effort. Creating a black-box FDD model requires a sufficient quantity and diverse types of operational data for machine learning. Since operation data for HVAC systems in existing nuclear cycle facilities are not fully available, so efforts to establish a monitoring system enabling the collection, storage, and management of sensor data indicating the status of HVAC systems and buildings should be prioritized. Once operational data are available, well-known machine learning methods such as linear regression, support vector machines, random forests, artificial neural networks, and recurrent neural networks (RNNs) can be used to classify and diagnose failures. The challenge with black-box models is the lack of access to failure data from operating facilities. To address this, one can consider developing black-box models using reference failure data provided by IEA or ASHRAE. Given the unavailability of operation data from the operating NFC facilities, there is a need for a short to medium-term plan for the development of a physics-based FDD model. Additionally, the development of a monitoring system to gather useful operation data is essential, which could serve both as a means to validate the physics-based model and as a potential foundation for building data-driven model in the long term.

Emotion AI, a subset of AI that measures, understands, responds to, and elicits human emotions, is an emerging area that has great potential for advertising research and practice. Studies on the applicability of emotion AI in advertising and marketing have been growing in academic journals. This rapidly burgeoning scholarship creates a need for advertising scholars to comprehend the current status of the research on emotion AI in advertising as well as opportunities and challenges that this new technological development will bring to. Thus, this study aims to offer an overview of research on emotion AI in advertising to identify the scope of existing research, gaps in knowledge, and opportunities and challenges that lie ahead.

The attitude-behavior gap and intention-behavior gap has not been research extensively. The purpose of this study is to provide a review of moderating or mediating factors on the relationship between intention or attitude and behavior of sustainable tourism. Intention was defined as the degree of a human being’s resolve to perform a certain action. The construct ‘Intention” has been used widely in some theories like the Theory of Planned Behavior. Researchers usually include the intention construct into their research framework to explain the theoretical mechanism. Sustainable or ecological tourism education has been implemented for years and empirical evidence provides us that almost all tourists are alerted to the importance of sustainability. There is a great challenge that tourists’ behavior might not concur with their intention. Policymakers and marketers really want to know the real factors affecting the association between the intention and behavior of sustainable tourism. Tourists’ purchase intention is a rational process and is affected by safety. Tourist behavior is associated with price and service environment which is a mixture of rational and emotional considerations.

Over the past decade, in-feed native advertising has become one of the most popular forms of online advertising, attracting attention from both academia and industry. Compared to traditional online ads, in-feed native ads are less intrusive and have more engaging content, effectively reducing users' tendency to avoid ads and improving advertising effectiveness. Despite existing review studies, most of them focus on specific aspects of in-feed native advertising, such as ad identification, disclosure, or regulation, and lack an overview of the relevant literature. Moreover, with the diversified development of digital media forms, the widespread application of AI technologies, and the improvement of consumers' ad literacy, in-feed native ad research faces new issues and practical challenges. Thus, a systematic review of existing research is necessary to identify valuable future research directions.

Purpose: This study analyzed domestic studies on blended learning among nursing students to identify research trends and future directions. Methods: This scoping review was conducted following the process suggested by Arksey and O’Malley: 1) identifying the research questions; 2) searching for relevant studies; 3) study selection; 4) charting the data; 5) collating, summarizing, and reporting the results; and 6) optional consultation. Relevant studies were searched using the keywords “blended learning” and “nursing” in the domestic databases RISS, KISS, and DBpia. The selection and exclusion criteria were applied to 203 articles, and 34 were finally selected. Results: The final 34 studies included 30 quantitative and four qualitative studies. Most of the studies were experimental studies. In undergraduate nursing education, blended learning was utilized more in the classroom than in the lab or clinical setting. Furthermore, it was mainly applied by combining online and offline approaches. It improved learning satisfaction, critical thinking, clinical performance, and self-directed learning ability. Conclusion: Research on blended learning in nursing education has increased over time. Blended learning positively affects learning satisfaction and learning ability in nursing students; thus, it is expected that this could be effectively utilized in both the classroom and lab or in clinical teaching for nursing students. Therefore, future studies using various research methods should be expanded, and systematic reviews and meta-analyses are recommended.

This study aims to promote the necessity for future research from the perspective of the indoor environment by analyzing the trend of domestic COVID-19 confirmed cases and examining previous quantitative research cases. The limitations of the qualitative management plan were identified by analyzing the trend of confirmed cases and deaths in Korea and the trend before and after the implementation of 'social distancing' and 'step-by-step daily recovery', which are actually being applied. The trend of initial and follow-up measures for the outbreak of infectious diseases in Korea is judged to be a case where the importance of qualitative and quantitative management should be confirmed to prepare absolute quarantine measures. The results suggest that examining previous research cases and preparing through advanced research for effective application.

This study investigated the potential role of dietary factors associated with obesity and metabolic syndrome (MetS) in Koreans. The scoping review method was used to evaluate the studies that utilized the secondary data sets comprising the Korean National Health and Nutrition Examination Survey (KNHANES) and the Korean Genome and Epidemiology Study (KoGES). Articles published between 2012 and 2022 were identified using RISS, KISS, DBpia, PubMed, and ScienceDirect databases. In all, there were 32 published articles on obesity and 119 on MetS. Obesity research included eight articles on nutrients, 12 on food items/food groups, two on dietary patterns, nine on dietary behavior/eating habits, and one on the dietary index. MetS studies comprised 34 articles on nutrients, 43 on food items/food groups, seven on dietary patterns, 25 on dietary behavior/eating habits, and 10 on the dietary index. Carbohydrates, alcohol, and coffee consumption were the most frequently studied dietary factors for obesity and MetS. The primary areas of study were largely focused on nutrients and food items/food groups. Thus, to overcome the paucity of information on the relationship of dietary patterns and dietary indexes with obesity and MetS, there is a need for further research using the KNHANES and KoGES data sets.

성명학은 ‘성씨와 이름관련 종합학문’으로 아주 넓게도 보나, ‘운명과 연관 된 작명학’으로 아주 좁게도 보면서 점술로 취급되기도 한다. 그러나 1990년 대부터 선행연구가 증가하면서 학술적 요건을 갖추어 가고 있으므로 이를 중 심으로 성명학의 학문적 정체성을 검토했다. 성명학 관련 연구는 10,321건으로 상당히 많지만, 최협의성명학의 학술과 학 위논문은 82건으로 많지 않다. 명칭은 성명학이지만 ‘운명연관 해명이 포함된 작명학’으로 범위를 좁히고 있기 때문에 학문적 영역이 상당히 좁고, 학술연구 분야분류에도 없는 무적 학문이다. 가르치는 교수나 대학(원)도 거의 없이 석사 와 박사만 배출되고 있어서 성명학의 향후 발전을 기대하기 힘들다. 이 같은 상황에서 논하기도 쉽지 않지만, 성명학 발전을 위한 학문적 정체 성 정립은 필수적이다. 이에 분석한 내용을 중심으로 제언하면, 첫째 성명학 은 운명론을 벗어나야 한다. 둘째 성명학의 범위 확대로 학문적 영역이 확보 되어야 한다. 셋째, 성명학의 학술연구분야분류가 필요하다. 넷째, 성명학 전 문가를 양성하는 대학(원) 교육이 시급하다.

Various types of karst topographies are found worldwide. Owing to their global distribution, karst areas have been extensively studied by scientists who investigate new discoveries by linking the characteristics of karst topographies with their own research fields. However, there have been only a few studies on karsts in the Republic of Korea, and little research exists on their hydrogeology. Fragmentary studies have been conducted on the hydrochemical characteristics of groundwater in limestone areas, the causes of high arsenic concentrations in groundwater, and the hydraulic conductivity of limestone areas. Research on hydrogeological characterization and flow mechanisms in these areas has only began recently. Identification and the proper management of available groundwater resources in karst (limestone) areas is essential as their unique geological characteristics render it difficult to construct reservoirs or dams at appropriate scales. We have reviewed prior work on karsts in the Republic of Korea to provide information that supports water resource security in the karst areas, to improve the understanding of the equitable use of water resources, and to identify the best management practices for groundwater resource resilience improvement.

Dry storage cask facilities are considered for temporary storage of spent nuclear fuels before their final disposal. According to relevant domestic laws and regulations, the integrity and gross defects of the PWR spent fuel must be inspected before they are transferred to the dry cask from a wet storage pool of a nuclear power plant. To meet nuclear safeguards requirements for a spent fuel transportation, the KINAC has been working to develop a simple and convenient Non-destructive Testing (NDT) equipment to verify the integrity and gross defects of the spent fuel assembly. This study was conducted in two processes. The first stage is to review the current NDT techniques conducted in the nuclear fuel manufacturing process. During the manufacturing process, the Ultrasonic testing (UT) and Eddy Current Testing (ECT) technique are used for detecting the cracks or foreign materials in a cladding of a fresh fuel. During an over-haul period after an end of one fuel cycle, the sipping test of the spent fuel is performed for detecting the failed fuel assemblies. If it is determined through the sipping test whether any fuel assembly contains a failed fuel rod, the failed fuel rod of lots of fuel rods in the assembly is found out using the UT instrument. The ECT is used for detecting the internal defects and oxide layer thickness of a fuel cladding. Because the UT and ECT are the wellknown technique and has already been employing for the spent fuel inspection, we adopted the UT and ECT technique for development of a new instrument for nuclear safeguards verification. The second stage is to design the UT and ECT equipment in consideration of nuclear safeguards activities in the spent fuel pool. For nuclear safeguards inspection, irradiated fuel or non-fuel items are distinguished. Thus, verification equipment newly designed using the UT and ECT should detect not only a failed rod, but also a false tube, or a false rod, or a different material from a cladding. New probe and signal processing methods are developed to achieve these goals. The design of UT and ECT probes are preferentially carried out according to technical requirements – the probe thickness including a damper material should be less than 1.0 mm - and the study on analyzing signal distortion caused from material difference will be conducted for development of the safeguards inspection equipment. Detailed results of our study will be discussed in this conference.
