Rural area development projects are being carried out in a strategy to create new value in agriculture and farm villages and to change the public perception. This study targeted rural experience participants visiting Cheong-Ho region, where the Rural Village Comprehensive Development Project was carried out. They were surveyed about attributes of visits to farm villages to determine which attributes of the experience could influence their revisits. This study was conducted under an umbrella project conducted as per the Special Act on Life Improvement and Regional Improvement for Farmers and Fishermen. Cheong-Ho region in Buan-gun produces mulberry, organic wheat, and rice grown using environmentally-friendly agricultural practices. This region as held events offering visitors the chance to experience rural villages and mulberry farms. Survey results showed that the natural landscape of villages, village experience, and the services provided by residents had a positive relationship with the probability of revisiting the village. Also, village facilities, harmony of natural landscape, hospitality of village residents, amusement value of rural experience, and the cost for rural experience were significant attributes. Therefore, it is necessary to revitalize the rural experience program targeting rural experience participants in Cheong-Ho region through continuous and monitoring of key visit attributes and revisit factors.

Sewers are important national infrastructure and play an essential part by handling both wastewater and stormwater to minimise problems caused to human life and the environment. However, they can cause urban flooding when rainfall exceeds the system capacity. Sewer flooding is an unwelcome and increasingly frequent problem in many urban areas, and its frequency will increase over time with urbanisation and climate change. Under current standards, sewers are designed to drain stormwater generated by up to 10 year return period storms, but data suggests that many in practice have been experienced flooding with exceeding system capacity under increased storm events. A large number of studies has considered upgrading or increasing the design standard but there are still lack of information to propose a suitable return period with the corresponding system quantity to achieve. A methodology is required to suggest a proper level of standard within a suitable sewerage rehabilitation planning that can avoid the exceedance problem. This study aimed to develop a methodology to support effective sewer rehabilitation that could prevent urban flooding mainly resulted from the exceedance of existing storm sewer system capacity. Selected sewerage rehabilitation methods were examined under different storm return periods and compared to achieve the best value for money.

Purpose: This study was conducted to verify the validity and reliability of the modified Transition Shock Scale for use among nursing students. Methods: From March 8-April 3, 2018, 207 nursing students participated in this study and were asked to complete self-reported questionnaires, including transition shock, clinical stress, and adapting to clinical practicums. The IBM SPSS Win 18.0 and AMOS 18.0 programs were used for data analysis. Results: A confirmatory factor analysis supported good convergent and discriminant validities ($x^2/df=1.58$, TLI=.92, CFI=.95, RMSEA=.053, AVE=.51-.68, CR=.75-.68). Correlations among transition shock, clinical stress (r=.34, p<.001), and adapting to clinical practicums (r=-.54, p<.001) were significant. Cronbach's alpha for the overall scale was .85, and for the six subfactors it ranged from .65 to .75. Conclusion: The findings suggest that the 17-item transition shock questionnaire is an appropriate instrument for measuring nursing students' transition shock with good validity and reliability.

A 42-year-old patient with functional dyspepsia had suffered from early satiation and postprandial fullness for 1 year despite Western medicine treatment. We treated her with the Spleen Daoyin method, along with acupuncture, moxibustion, and herbal medicine and scored her symptoms using a 4-point Functional Dyspepsia-related Quality of Life (4p-FD-QoL) questionnaire, the Gastrointestinal Symptom Rating Scale (GSRS), and a visual analogue scale (VAS). A 7-day Spleen Daoyin treatment decreased her 4p-FD-QoL score from 61 to 51, with a marked decrease in the emotional part (18 to 10). Her GSRS score did not change, but her bloating score decreased from 3 to 1. Her VAS score decreased from 6.6 to 4.3 for upper abdomen discomfort, but lower abdomen discomfort was unchanged. The patient showed high compliance and satisfaction with exercise therapy and reported no adverse events. Spleen Dayoin may be a useful therapy for functional dyspepsia, especially when accompanied by psychological problems.

The blanket plays an important role in fusion reactor and stands extremely high thermal and electromagnetic loads during operation situation and plasma disruption event, brings the need for precise thermal and electromagnetic analysis. Since the thermal field and EM field interact with each other nonlinearly, we develop a method of electromagnetic-thermal two-way coupling by using finite element software COMSOL. The coupling analyses of blanket under steady state and MD event are implemented and the results are analyzed. For steady state, the influences of coupling effects are relatively small but still recommended to be considered for a high precision analysis. The influence of thermal field on EM field can't be ignored under MD events. The variation of force density could cause a significant change in stress in certain parts of blanket. The influence of Joule heat during MD event is negligible, yet the potential temperature rise caused by induced current after MD event still needs to be researched.

Stormwater reduction plays an important role in the safety and resilience to flooding in urban areas. Due to rapid climate change, the world is experiencing abnormal climate phenomena, and sudden floods and concentrated torrential rains are frequently occurring in urban basins and the amount of outflow due to stormwater increases. In addition, the damage caused by urban flooding and inundation due to extreme rainfall exceeding the events that occurred in the past increases. To solve this problem, water supply, drainage, and water supply for sustainable urban development, the water management paradigm is shifting from sewage maintenance to water circulation and water-sensitive cities. So, in this study, The purpose of this study is to examine measures to increase the resilience of urban ecosystem systems for urban excellence reduction by analyzing the effects of green infra structures and LID techniques and evaluating changes in resilience. In this study, for simulating and analysis of runoff for various stormwater patterns and LID applications, Storm Water Management Model (SWMM) was used.

Urban floods pose significant challenges to cities worldwide, driven by the interplay between urbanization and climate change. This review examines recent studies of urban floods to understand their causes, impacts, and potential mitigation strategies. Urbanization, with its increase in impermeable surfaces and altered drainage patterns, disrupts natural water flow, exacerbating surface runoff during intense rainfall events. The impacts of urban floods are far-reaching, affecting lives, infrastructure, the economy, and the environment. Loss of life, property damage, disruptions to critical services, and environmental consequences underscore the urgency of effective urban flood management. To mitigate urban floods, integrated flood management strategies are crucial. Sustainable urban planning, green infrastructure, and improved drainage systems play pivotal roles in reducing flood vulnerabilities. Early warning systems, emergency response planning, and community engagement are essential components of flood preparedness and resilience. Looking to the future, climate change projections indicate increased flood risks, necessitating resilience and adaptation measures. Advances in research, data collection, and modeling techniques will enable more accurate flood predictions, thus guiding decision-making. In conclusion, urban flooding demands urgent attention and comprehensive strategies to protect lives, infrastructure, and the economy.

During the past 65 million years, Alu sequences have been amplified through RNA-polymerase IIIderived transcripts, and have reached the copy number of about 1.4 million in primate genomes. They are the largest family among mobile genetic elements in human genome and consist of ten percent of the human genome. Alu sequences are thought to be functionless genetically, but many researchers have proved new function and disease implication. Alu elements make the genome insertional mutation, Alu-mediated recombination events, and unexpected splicing site and change gene structures, protein sequences, splicing motifs and expression patterns. In this review, the structure and origin of Alu, consensus sequences of Alu subfamilies, evolution and distribution of Alu, and their related diseases were described. We also indicated new research direction of Alu elements in relation to evolution and disease.
