  • Background: The aim of this study was to research the importance of the neutrophil to lymphocyte ratio (NLR) in prediction of PSA recurrence after radical prostatectomy, which has not been reported so far. Materials and Methods: The data of 175 patients who were diagnosed with localised prostate cancer and underwent retropubic radical prostatectomy was retrospectively examined. Patient pre-operative hemogram parameters of neutrophil count, lymphocyte count and NLR were assessed. The patients whose PSAs were too low to measure after radical prostatectomy in their follow-ups, and then had PSAs of 0,2 ng/mL were considered as patients with PSA recurrence. Patients with recurrence made up Group A and patients without recurrence made up Group B. Results: In terms of the power of NLR value in distinguishing recurrence, the area under OCC was statistically significant (p<0.001) .The value of 2.494 for NLR was found to be a cut-off value which can be used in order to distinguish recurrence according to Youden index. According to this, patients with a higher NLR value than 2.494 had higher rates of PSA recurrence with 89.7% sensitivity and 92.6% specificity. Conclusions: There are certain parameters used in order to predict recurrence with today's literature data.We think that because NLR is easy to use in clinics and inexpensive, and also has high sensitivity and specificity values, it has the potential to be one of the parameters used in order to predict biochemical recurrence in future.

  • The purpose of this study was to analyze forest vegetation structure in Marugeum (the ridge line) area between Dakmokryeong and Daetjae in Baekdudaegan through vegetation classification, importance value, species diversity, and CCA using the data that were collected from 245 quadrates through Braun-Blanquet vegetation survey method from May to September in 2017. The results of the forest vegetation classification identified 8 vegetation units with Quercus mongolica community group at the highest level. Q. mongolica community group was classified into the Cornus controversa community, Buxus koreana community, Sasa borealis community, Abies nephrolepis community, and Q. mongolica typical community. C. controversa community was further classified into Quercus dentata group, Filipendula glaberrima group, Larix kaempferi group, and C. controversa typical group. The result of the important value analysis showed that Q. dentata had the highest importance value at 19.1% in vegetation unit 1 while Q. mongolica had the highest importance value at 22.7%, 38.3%, 25.6%, 41.3%, 27.9%, and 41.6% in vegetation unit 2, 4, 5, 6, 7, and 8, respectively, and L. kaempferi had the highest importance value at 27.6% in vegetation unit 3. As such, Q. mongolica species generally represented the communities of Marugeum (the ridge line) area of Dakmokryeong to Daetjae in Baekdudaegan. The results of species diversity showed that vegetation unit 1 and 2 were 3.305 and 3.236, respectively, which were relatively higher than other vegetation units. It was considered that this result was due to the influence of high emergence of present species. The results of the CCA analysis of the correlations between biotic environmental factors and vegetation types showed that vegetation unit 1 was mainly correlated with the megaphanerophyte ratio and vine plant ratio. In the correlations between abiotic environmental factors and vegetation types, vegetation unit 7 was significantly correlated with altitude. From the perspective of ecological management, vegetation unit 5 represented by B. koreana community was inhabited by a variety of plants due to the species composition and location environment due to the geological characteristics that are typical of limestone area. Vegetation unit 7 represented by A. nephrolepis community was typified as subalpine vegetation widely distributed by relict species and endemic species. We concluded that it is necessary to manage these vegetation units with an ecologically differentiated approach.

  • With respect to the quantity, quality and social value of forest jobs, we have developed three major criteria and 11 indicators for evaluating decent forest jobs. The importance and weighted value of the criteria and indicators were investigated through a survey which was conducted on 50 experts involved in Governmental Forest Job Committee, academic and different groups of communities. The 35 experts responded to the survey chose the 'job creation potential' as the most important criterion, and they recognized the 'job quality' has a relatively higher importance than the 'social contribution'. The survey results showed that 'political will' and 'job security' have the highest weighted values among indicators while 'wage level' has the lowest value. The developed criteria and indicators are able to be used as a means of evaluating degree of decent forest jobs for both new and existing jobs.

  • This study show the service value and the service quality influence on the satisfaction of the participants in exhibition. Previous studies, from the general service quality to customer satisfaction research, begin to focus on the importance of service quality and customer satisfaction, so focus on the service value that explains revisiting behavior and loyalty as an important variable. This study mainly attempted integrated approach of various concepts between relationship. This point the service value did not sufficiently consider tries to evaluate the role of customer value in existing service quality and satisfaction. As a result, service quality and service value were identified to causal relationships that service value rather than service quality has an effect on satisfaction.

  • This study was conducted to obtain the fundamental data for the ecological management in the Pinus koraiensis natural forest in Seoraksan National Park. The community types of the P. koraiensis forest were divided into Ainsliaea acerifolia group and Rhododendron schlippenbachii group. A. acerifolia group was subdivided into Acer tschonoskii var. rubripes subgroup and Calamagrostis arundinacea subgroup. The importance value of major species showed higher value in the order like Pinus koraienses, Abies nephrolepis, Acer barbinerve, Betula ermani, Acer pseudo-sieboldianum, Sorbus commixta and Quercus mongolica. The value of species diversify ranged from 0.44 to 0.86, and showed stronger competition in the interspecific association than in the intraspecific one. The number of individuals of P. koraiensis below 10 centimeters in the 15 study sites was 35, and it was considered that the population of P. koraiensis could be succeeded to the other species in the present situation because of lower frequency in the low layer though the canopy of tree layer was dominated with P. koraiensis. The radial growth patterns of P. koraiensis individuals were mainly fluctuated for the entire life time, which was considered to be caused by frequent disturbance.

  • In the uncertainty fueled by the COVID-19 pandemic, mergers and acquisitions (M&As) have emerged as key strategic responses by firms. This study explores the impact of M&As on acquirers' firm value, utilizing a firm-level panel dataset from SDC Platinum. Empirical evidence recognizes the potential negative impact of transaction value in M&As and the pandemic's effect on market uncertainty that may occasionally exacerbate the adverse influence on acquirers' firm value. The findings indicate that effective marketing strategies, such as enhancing consumer awareness through increasing advertising expenditures, can counterbalance these influences, particularly during uncertain times. This study accentuates the importance of adaptability and a responsive marketing approach in managing M&As during a global crisis. It provides valuable perspectives on consumer awareness in strategic decision-making, offering insights for both academic and business communities and focusing on actionable strategies for navigating the global market turmoil transformed by COVID-19.
