Journal of Korean Academy of Nursing Administration 2023;29(2):109-118
Purpose:
This study examined the effects of work environment, job engagement, and positive psychological capital on hospital nurses’ job embeddedness.
Methods:
Participants were 118 hospital nurses. Data were analyzed using descriptive statistics, independent t-test, One-way ANOVA, Pearson correlation coefficients, and multiple regression analysis using SPSS/Win 25.0.
Results:
Mean work environment was 2.70±0.14, mean job engagement was 3.03±0.42, positive psychological capital was 4.05±0.27, and job embeddedness was 3.24±0.31. There were significant differences in job embeddedness by turnover experience and current working hospital type. The factors influencing the job embeddedness of the hospital nurses were turnover experience, current working hospital type, and nurse manager ability, leadership, and nueses’ support in the work environment. It was found that 23% could explain job embeddedness.
Conclusion
Implementing a nurse support program related to turnover experience and type of hospital is necessary to enhance job embeddedness. The results indicate a need to develop a coaching program for cultivating leadership and supporting nurses to improve job embeddedness.

BACKGROUND AND OBJECTIVES: Imidapril, one of the ACE inhibitor, has been used to treate hypertension, congestive heart failure, diabetes mellitus and renal disease. ACE inhibitor, however often causes dry cough and this adverse effect affects the compliance rate negatively. This report aimed to examine the incidence rate of coughing caused by Imidapril treat-ment. And we compared the results with the incidence and tendency of dry cough caused by the other ACE inhibitors. MATERIALS AND METHOD: This study enrolled 38 patients who followed up at internal medicine and took Imidapril from the period of May 9, 1997 to December 17, 1997. We tested its effectiveness, safety and tolerance. The initial dosage of it was 5mg/day and the maximum dosage according to blood pressure was 10mg/day for 8 weeks. The tendency and the incidence of dry cough have been analyzed and compared with recently published Korean reports. RESULTS: The 5 mg dosage of Imidapril showed 68.1% in lowering blood pressure rate and it went up to 81.8% during the 8 weeks treatment perriod. The blood pressure regularity rate was 36.3% after the 8 weeks treatment. The overall rate of adverse effect occurrence was 26.1% (6/23) and 8.7% of them were likely to cough. One of the patients who showed nausea stopped medication. The recent articles reported that the incidence of dry cough had been reduced: Enalapril (33.8%), Fosinopril (16%), Ramipril (15%), Imidapril (7.8 - 8.7%), Losartan (4.3%). CONCLUSION: Imidapril is as safe and effective as other ACE inhibitors. Various ACE inhibitors that were newly developed show their effectiveness in lessening incidence rate of dry cough, and Imidapril is thought to be an excellent drug for this matter. Even though Losartan shows the lowest incidence rate of dry cough, it needs to more regular usages since it is still on the stage of its medical adaptation.

The genus Mitrula (Mitrulaceae, Helotiales), as also known as swamp beacons, inhabits submerged, decaying vegetation in standing or decaying needles, twigs, leaves, and shallow water. They play an important role in carbon cycling in some freshwater ecosystems. In the herbarium of the Korea National Arboretum (KH), seven Mitrula specimens were collected during mushroom forays in the period from 2019 to 2021. The Korean collections were found to be macromorphologically closely related to M. paludosa and M. elegans, but micromorphologically they could be distinguished by characteristics of slightly narrower asci and aseptate ascospores. Our molecular phylogenetic analyses of the internal transcribed spacer (ITS) and 28S rDNA regions also revealed that our specimens were related to M. paludosa and M. elegans, but formed a distinct clade. Based on these results, we reported our specimens as new to science and discussed the phylogeny and diversity ofMitrula species.

To improve our understanding of the relationship between soil higher fungi (belonging to Ascomycota and Basidiomycota) and Abies koreana, we surveyed A. koreana soil fungal communities in a forest in Mt. Halla, Jeju Island, Korea by next-generation sequencing (Illumina Miseq). To confirm the soil higher fungal communities, we collected two types of soils from a defined plot: soils with dead (AKDTs) and living A. koreana (AKLTs), respectively. Soil fungi were classified into 2 phyla, 19 classes, 64 orders, 133 families, 195 genera, and 229 OTUs (895,705 sequence reads). Nonmetric multidimensional scaling (NMDS) showed significantly different soil higher fungal communities between AKDTs and AKLTs (p < .05). In addition, the saprophyte composition was significantly affected by A. koreana status (p < .05). The proportion of the mycorrhizal Clavulina spp. was different between soils with AKDTs and AKLTs, suggesting that Clavulina spp. may be a crucial soil fungal species influencing A. koreana. This study will lead to a better understanding of the ecological status of A. koreana in Mt.Halla. In addition, this study could be useful for the conservation and management of A.koreana habitats.

Acarosporaceae is a crustose lichen and is known as a species that has more than 50 multispores, and has hyaline spores. Those taxa are often found in rock and soil in mountain areas or coastal regions in Korea, and very diverse forms and species are known. However, after an overall genetic phylogenetic analysis of carbonized ascomata in 2015, species consisting only of the morphological base are newly divided, and several species of Acarosporaceae in Korea are also being discovered in this situation. As a result of analysis using internal transcribed spacer (ITS) and nuLSU gene analysis, Korean species belonged to Acarospora and Sarcogyne clade, and i>Acarospora classified as the Acarospora clade was mixed with the Polysporina group and the Sarcogyne clade is mixed with the Acarospora. We identified two new species (Acarospora beangnokdamensis J. S. Park & S. O. Oh, sp. nov., Sarcogyne jejuensis J. S. Park & S. O. Oh, sp. nov.) through morphological, molecular, and secondary metabolite substance and found one new record (Sarcogyne oceanica K. Knudsen & Kocourk). We have made a classification key forAcarospora and Sarcogyne in Korea and reported all information together here.

The Tian Shan mountain system is one of the large mountain ranges located in Central Asia. This region is globally recognized as mountain ranges, offering inestimable wealth in fauna and flora with significant biodiversity values. We surveyed macrofungal diversity of Tian Shan in Kyrgyzstan from 2016 to 2018. A collection of macrofungi was made, and these were subjected to sequence comparisons and phylogenetic analysis to ensure the identity of the collected macrofungi. Of those collected, 95 out of 100 specimens were successfully sequenced and compared with those of other related species retrieved from GenBank. The sequenced specimens were classified into 2 phyla, 8 orders, 24 families, 47 genera, and 57 species, based on current taxonomic concepts (combining morphology and phylogeny). To the best of our knowledge, this study provides the first well-documented checklist and phylogenetic analysis of macrofungi recovered from the Tian Shan mountains in Kyrgyzstan.

During the 2014 survey of the mushroom flora of Gwangneung forest in South Korea, we collected two specimens of boletoid mushroom growing on a felled tree of Pinus koraiensis. These specimens were characterized by a light brown to reddish-brown pileus with appressed tomentum, pore surface bluing instantly when bruised, golden-yellow mycelium at the base of stipe, and lignicolous habitat. Both specimens were identified as Buchwaldoboletus lignicola, a rare basidiomycete, based on morphological characteristics and sequences of internal transcribed spacer (ITS; fungal barcode). Here, we describe these specimens and provide the first report of this genus in South Korea.

Amanita Pers. is a well-known monophyletic mushroom genus with a broad distribution. However, the diversity of Korean Amanita species has been underestimated, and most taxonomic studies conducted in Korea have only investigated their morphological characteristics. This approach is frequently insufficient for correct identification in fungal classification; therefore, we constructed a phylogeny of Amanita subgen. Lepidella in order to understand the phylogenetic placements of 16 Amanita specimens collected in Korea in 2012. The phylogeny constructed using the sequence data of the internal transcribed spacers and the partial large subunit of ribosomal RNA identified nine Amanita species (A. citrina, A. excelsa var. spissa, A. flavipes, A. fritillaria, A. oberwinklerana, A. pallidorosea, A. rubescens, A. subjunquillea, and A. volvata); of these, A. fritillaria, A. oberwinklerana, and A. pallidorosea are new to Korea.

We conducted five times surveys, in June, September and October in 2012; June and September 2013, to catalog the mushroom flora in Ulleung-gun, Republic of Korea. More than 400 specimens were collected, and 317 of the specimens were successfully sequenced using the ribosomal DNA internal transcribed spacer barcode marker. We also surveyed the morphological characteristics of the sequenced specimens. The specimens were classified into 2 phyla, 7 classes, 21 orders, 59 families, 122 genera, and 221 species, and were deposited in the herbarium of Korea National Arboretum. Among the collected species, 72% were saprophytic, 25% were symbiotic, and 3% were parasitic. The most common order was Agaricales (189 specimens, 132 species), followed by Polyporales (47 specimens, 27 species), Russulales (31 specimens, 22 species), Boletales (10 specimens, 7 species), and so on. Herein, we also reported the first Bovista species in Korea, which was collected from Dokdo, the far-eastern island of Korea.

The diversity of the genus Megacollybia in Korea was examined based on morphological observation and analysis of molecular data. Currently, the genus is consisted of nine species with a global distribution. However, only M. platyphylla has been reported in the floral survey of Korea. During our re-evaluation of the taxonomic diversity of Megacollybia in Korea, six Megacollybia specimens collected in 2012 were identified based on internal transcribed spacer (ITS) sequences and morphology. Here, we report two Megacollybia species, M. clitocyboidea and M. marginata, as newly recorded species from Korea. The microscopic features of the two species are provided in this study. To our knowledge, this is the first phylogenetic analysis of Korean Megacollybia species.
