This study analyzed the monitoring results of fishways at 16 weirs constructed on four large Rivers to provide data helpful for the operation and management of fishways. The average utilization rate of the fishways at the weirs was confirmed to be 64.9%. When comparing the dominant species in the mainstream and fishway monitoring results, differences were observed in 9 weirs (56.3%). This indicated that the species prevalent in the mainstream were not necessarily the ones most frequently using the fishways. The average number of individuals using the fishways per day was 336. When classifying the fish species using the fishway by life type, 92.3% were primary freshwater fish, and migratory species accounted for only 5.6%. Analysis based on the season of fishway usage revealed that an average or higher number of fish species used the fishways from May to October, with the highest number of individual users occurring from June to August. Between May and July, 80% of the fish species using the fishways were in their spawning period, while during other season, less than 40% were species that move during the spawning period. The fishways that showed a significant alignment between the spawning period and the fishway passage period were Rhinogobius brunneus, Leiocassis nitidus, Squalidus chankaensis tsuchigae, Pseudogobio esocinus, Acheilognathus rhombeus, and Pungtungia herzi, in that order. When comparing the fishway monitoring results of the Gangjeong-Goryeong Weir and the Dalseong Weir with the upper part water level of the weir, both the number of fish species and individuals using the fishway showed positive correlations with the upper part water level of the weir. This suggests that a higher water level of the weir increases the inflow discharge within the fishway, leading to increased use by fish (number of individuals in Gangjeong-Goryeong Weir, P<0.001; number of species in Dalseong Weir, P<0.05). This study summarized and analyzed the results of fishway monitoring at 16 weirs built on four large Rivers, considering fishway efficiency, operation and management, monitoring period, and regulation of water level in the upper part of the weir. It is thought that this will help understand the status of fish use in fishways on large River and aid the construction, operation, and management of fishways in the future.

The study confirmed the "house search report(家宅搜索調書)" containing criminal records during the Japanese colonial period, as well as the production process and the way of expressing the illustrations contained in them. It also explored architectural values through analysis of the location and use of the building. This records the discovery of evidence by searching the residences of those involved in the crime from 1919 to 1922. The illustrations contained in this record were not standardized, so the contents of the article differed depending on the author's background and cultural experience. Nevertheless, this painting reflects the regional characteristics of traditional houses located throughout the Korean Peninsula. It is also evidence that the house was used for cultural, commercial, and industrial purposes, beyond the general assumption that it was used only for residential purposes. The "House Search Report(家宅搜索調書)" provides information on ordinary buildings that existed as the background of everyday life, rather than buildings with a specific purpose or exceptional design. It is evaluated as an important resource for understanding the diverse life and spatial structures of buildings during that time.

Freshwater jellyfish, a type of jellyfish exclusively found in freshwater, has a limited number of species but is found globally. However, their ecology and causes of occurrence are largely unknown. Therefore, understanding the distribution of polyps, which produce the larvae of freshwater jellyfish, can provide important data for comprehending their ecology. This study aims to explore the COI gene of freshwater jellyfish using environmental DNA from the microbial film in the Miho River system. Among the 12 survey points in the Miho River watershed, genetic material of freshwater jellyfish was detected in 8 points, mainly located upstream near reservoirs. These genetic materials were identified as genes of the well-known freshwater jellyfish species, Craspedacusta sowerbii. Notably, the C. sowerbii genes found in the Miho River watershed survey points were closely related to a species previously discovered in Italy. Consequently, utilizing environmental DNA to explore the genetic traces of freshwater jellyfish enables rapid screening of areas with a high likelihood of freshwater jellyfish occurrence. This approach is deemed to provide crucial information for understanding the distribution and ecology of freshwater jellyfish in Korea.

'Hanabell' is a new ornamental crabapple cultivar bred in 2020 at the Apple Research Institute, National Institute of Horticultural and Herbal Science, Rural Development Administration. It was selected from seedlings obtained through the open-pollination of Malus baccata collected from Mt. Palgong, Gunwi-gun, and Gyeongsangbuk-do. Line selections were conducted from 2009 to 2016, and characteristic tests were evaluated from 2017 to 2019. The tree vigor and form of 'Hanabell' were determined to be medium and spreading, respectively. The flowering season of 'Hanabell' starts on April 17th and ends on May 2nd, lasting approximately 15 days. The size of 'Hanabell' flowers is approximately 48 mm, larger than that of general apple flowers, and they have a high ornamental value due to the abundance of blooms each year. Furthermore, 'Hanabell' possesses a distinct floral scent that releases a significant amount of benzyl acetate (C9H10O2) into the air during flowering, attracting bees. Subsequently, 'Hanabell' was officially submitted for variety protection to the KoreaSeed & Variety Service in 2021(Applicationno.2021-144).

Recently, local studies looking at the 'local(region) as a whole' are gradually increasing. The study of local architectural history is important in that it provides specific information that encompasses the local and the entire and clues to three-dimensionalize the time and space in the local. To infer the 'presentness' of each era, reliable data in various fields are needed. Recently, as many databases (DB) and archives, from the 'National Archives of Korea' to other local archives, have been established and publicized, research resources in the local are growing rapidly in quantity and quality. Nevertheless, it is difficult to comprehensively check the data necessary to study the local architectural history(local architectural history research resources). Against this background, this study confirmed the trend of changes in the archive construction environment and the status and problems of local architectural history research resources in places that currently disclose local history research resources among generalized web-archives. Next, the relationship between the actual research on local architectural history was confirmed through the analysis of existing studies and the data used for Jeju. As a result, local studies, local archives, and local architectural history research agree with recent changes in local research trends, and the degree of archival construction has reached the same level as the available research resources except core data in local architectural history research. However, there is a problem that the density of information that can be used is low because the local architectural history research resources that can be obtained are fragmented because there are no archives and construction entities specialized in local architecture. As each archive has entered the stabilization and upgrading stage, the construction of new archives needs to be reconsidered, but it is time to find a detailed way to link related information quickly and accurately, such as private records, to reduce the gap in information needed in terms of research on local architecture and architecture history.

Purpose: This study aimed to explore nursing simulation training needs and the educational environment of instructors. Method: This study was conducted according to the inductive method of qualitative content analysis. An online focus group interview was conducted with six instructors with experience operating a nursing simulation. Data were collected in July 2021. Results: First, “nursing simulation practice operations” required simulation design elements, practical operations, and curriculum integration. Second, the “educational environment” showed a lack of human and physical resources, and there was a need for standard education reflecting the domestic nursing education environment. Third, for “instructor competencies”, the facilitator role, step-by-step education for strengthening instructor competencies, and cooperation with clinical experts were derived. Fourth, it was found that “learner competencies” should meet the nursing professionals’ needs; self-directed learning competency and unique human competency should also be strengthened. Conclusion: This study is meaningful because it seeks to understand the instructor’s needs for nursing simulation training and the educational environment. Moreover, it identifies considerations for instructor and learner competencies in the nursing simulation operator training programs.

Purpose: This study aimed to develop a faculty development program for nursing simulation on perceived knowledge, confidence, and competence, and then evaluate its effects. Method: A one-group pretest–posttest design was used. The eight-hour program covered simulation education theory, scenario design and development, simulation design and operation using patient simulators and standardized patients, debriefing, curriculum integration, simulation evaluation, and faculty development. Thirty-eight participants completed a self-administered questionnaire. Data were collected in August 2021. The study used paired t-tests to analyze differences in perceived knowledge, confidence, and competence before and after the application of the program. Results: The participants were generally satisfied with this program. The results indicated that knowledge, confidence, and competence for nursing simulation significantly improved. Conclusion: The faculty development program positively affected simulation instructors’ knowledge, skill, and attitude. Therefore, this validated and standardized training program can be used for training simulation faculty members at universities and institutions. It can not only reduce the cost and effort required for faculty development at each university but also ultimately contribute to the spread of nursing simulation.

Hepatic diseases are divided into two types: alcoholic and non-alcoholic. Non-alcoholic liver injury finally induces fatty liver and damages liver function. Many studies have demonstrated that Ecklonia stolonifera has antioxidative, antiinflammatory, and hepatoprotective activities. We conducted a 12-week double-blind, placebo-controlled, randomized trial to examine the efficacy of E. stolonifera extracts (ESE) on biochemical markers of hepatic function. Sixty-five subjects with mild or moderate liver injuries were randomly allocated to receive either 420 mg/d of ESE or a placebo for 12 weeks. Fifty-five participants completed the trial. No significant adverse events were observed among the subjects during the study. The primary end points were changes in plasma levels of aspartate transaminase (AST), alanine transaminase (ALT), and γ-glutamyltransferase (γ-GT). The secondary end points were changes in lipid profile levels, including total cholesterol (TC), triglyceride (TG), highdensity lipoprotein cholesterol (HDL), and low-density lipoprotein cholesterol (LDL). Compared with the baseline, AST and ALT levels decreased significantly in the ESE group compared to those in the placebo group (P<0.001). In addition, γ-GT levels in the ESE group were significantly lower than those in the placebo group (P=0.016). There were no differences in the TC, TG, HDL, and LDL levels between groups. In conclusion, ESE consumption for 12 weeks improved liver parameters in subjects with liver injury. Regular consumption of ESE could maintain liver health in individuals at risk of hepatic damage.

Estuary is important in terms of biodiversity because it has the characteristics of transition waters, created by the mixing of fresh- and seawater. The estuarine water circulation provides a variety of habitats with different environments by inducing gradients in the chemical and physical environment, such as water quality and river bed structure, which are ultimately the main factors influencing biological community composition. If the water circulation is interrupted, the loss of brackish areas and the interception of migration of biological communities will lead to changes in the spatial distribution of biodiversity. In this study, among the sites covered by the Estuary Aquatic Ecosystem Health Assessment, we selected study sites where changes in biodiversity can be assessed by spatial gradient from the upper reaches of the river to the lower estuarine area. The α-, γ- and β-diversity of diatom, benthic macroinvertebrates, and fish communities were calculated, and they were divided into open and closed estuary data and compared to determine the trends in biodiversity variation due to estuarine circulation. As results, all communities showed higher γ-diversity at open estuary sites. The benthic macroinvertebrate community showed a clear difference between open and closed estuaries in β-diversity, consequently the estuarine transects were considered as a factor that decreases spatial heterogeneity of their diversity among sites. The biodiversity trends analyzed in this study will be used to identify estuaries with low γ- and β-diversity by community, providing a useful resource for further mornitoring and management to maintain estuarine health.

Fish assemblage of total 325 of Korean peninsula estuaries were surveyed to analyze the characteristics of community structure and diversity by sea areas for three years from 2016 to 2018. The scale (stream width) of Korean estuaries were various (14~3,356 m), and 68.9% of all estuaries showed salinity of less than 2 psu. Total 149 species classified into 52 families of fish were identified, and the dominant and sub-dominant species were Tribolodon hakonensis (relative abundance, RA, 12.5%) and Mugil cephalus (RA, 9.5%), respectively. The estuary of the Korean Peninsula had different physical and chemical habitat environments depending on the sea area, and accordingly, fish community structure also showed statistically significant differences (PERMANOVA, Pseudo-F=26.69, P=0.001). In addition, the NMDS (nonmetric multidimensional scaling) results showed the patterns that indicating fish community difference by sea areas, even though low community similarity within sea area (SIMPER, 21.79~26.39%). The estuaries of east sea areas were distinguished from the others in the aspects of which, the higher importance of migratory fishes and endangered species, and that of brackish species were characterized at south sea estuaries. However, the estuaries of west sea showed higher importance of species that have a relation with freshwater (primary freshwater species, exotic species), which is the result that associating with the lower salinity of west sea estuaries because of the high ratio of closed estuaries (78.2%). The SIMPER analysis, scoring the contribution rates of species to community similarity, also showed results corresponding to the tendency of different fish community structures according to each sea area. So far, In Korea, most studies on fish communities in estuaries have been conducted in a single estuary unit, which made it difficult to understand the characteristics of estuaries at the national level, which are prerequisite for policy establishment. In present study, we are providing fish community structure characteristics of Korean estuaries in a national scale, including diversity index, habitat salinity ranges of major species, distribution of migratory species. We are expecting that our results could be utilized as baseline information for establishing management policies or further study of Korean estuaries.

‘Buddybell’ is a promising crabapple variety developed as a pollinizer at the Apple Research Institute, National Institute of Horticultural and Herbal Science, Rural Development Administration, Korea, in 2019. This variety was selected from seedlings obtained by natural crossing of Malus baccata. It was collected from Mt. Jeombong, Inje-gun, and Gangwon-do. Line selections were conducted from 2009 to 2016, and characteristic evaluations were performed from 2009 to 2010. Tree vigor and tree form of ‘Buddybell’ were medium and upright, respectively. The first flowering time was early, around April 16, and the flowering period was as long as 14 days. The flowers of ‘Buddybell’ were pink in the balloon stage and white in full bloom. ‘Buddybell’ has a high fruit setting rate with major apple varieties(‘Fuji’, ‘Hongro’, and ‘Tsugaru’). The amount of pollen weight per 1,000 inflorescence of ‘Buddybell’ was 2.5 times higher than that of 'Maypole'; hence, it is highly useful as a pollinizer in apple orchard. ‘Buddybell’ was officially applied for variety protection on Korea Seed & Variety Service in 2020 (Application no.2020-237).

This study was conducted on October 23, 2020 at the Cheongpyeong Reservoir located in Seorakmyeon, Gapyeong-gun, Gyeonggi-do, and analyzed the horizontal and vertical distribution patterns of fish based on data obtained using fishfinder. The total surface area of fishfinder survey conducted was 782,853 m2, and where the water depth (WD) ranges from 10 m to 12 m is widest which 31.7% of total surface area. As a result of the heat map analysis, fish density was highest at right bank under the Gapyeong-bridge, but there was no specific pattern in horizontal distribution of fish. As a result of vertical distribution of fish analysis, 86.6% of fishes are observed at below 6 m of the fish depth (FD, distance from water surface to fish). As a result of the relative height (RH, water depth-distance from bottom to fish ratio) analysis, there was a tendency that fishes are distributed in near surface area more as the WD increased. This tendency could have various reasons such as water temperature gradient along the water depth, and further studies are required for detailed explanation.
