  • Plants social network analysis, which combines plants society and social network analyses, is a new research method for understanding plants society. This study was conducted to investigate the relationship between species, using plant social network analysis targeting Taejongdae in Busan, and build basic data for management. Taejongdae, located in the warm temperate forest in Korea, is a representative coastal forest of Busan Metropolitan City, and the Pinus thunbergii-Eurya japonicacommunity is widely distributed. This study set up 100 quadrats (size of 100m2each) in Taejongdae to investigate the species that emerged and analyzed the interspecies association focusing on major species. Based on the results, a sociogram was created using the Gephi 0.9.2, and the network centrality and structure were analyzed. The results showed that the frequency of appearance was high in the order of P. thunbergii, E. japonica, Quercus serrata, Sorbus alnifolia, Ligustrum japonicum, and Styrax japonicusand that many evergreen broad-leaved trees appeared due to the environmental characteristics of the site. The plants social network of Taejongdae was composed of a small-scale network with 50 nodes and 172 links and was divided into 4 groups through modularization. The succession sere identified through a sociogram confirmed that the group that include P. thunbergiiand E. japonicawould progress to a deciduous broadleaf community dominated by Q. serrataand Carpinus tschonoskii, using hub nodes such as Prunus serrulataf. spontaneaand Toxicodendron trichocarpum. Another succession sere was highly likely to progress to an evergreen broad-leaved community dominated by Machilus thunbergiiand Neolitsea sericea, using M. thunbergiias a medium. In some areas, a transition to a deciduous broad-leaved community dominated by Celtis sinensis, Q. variabilisand Zelkova serratausing Lindera obtusilobaand C. sinensisas hub nodes was expected.

  • Since catastrophe from explosion of Hukushima nuclear power plant, concerns over possibility of exposure to radioactive matter has been disseminating all over the world and frequent accidents of domestic nuclear power plants also has been amplifying throughout the nation. In the past, major focus was made on compensation for local residents who live nearby nuclear power plants, but focal point of this study is on wage premium of workers who are employed in R&D of nuclear power plants. It is difficult to derive socially desirable result if private sectors are responsible for compensation on workers who suffer from physical damages due to the exposure to radioactive matter. Because victims should verify the damages that occur in the working places. This study conducted a survey on which job would prefer the respondents who are engaged with the nuclear R&D projects as exposure levels to radioactive matter, security of job, location of firms, and work intensity differ. As a result, exposure to radioactive matter was the most important attribute in choosing alternative jobs followed by job security, work intensity and job location. Annual willingness to pay for reduction of exposure to radioactive matter was estimated as 7730~7770 thousand KRW depending on different econometric models. Therefore, Korean government should prepare institutional foundation in order that appropriate compensation should be made on workers who are engaged in R&D projects on nuclear power plants if they have damages from the exposure to radioactive matter.

  • This study analyzed the relationship between communication perception and job performance in general hospital nurses in order to provide basic data for efficient personnel and hospital management. For this purposes, data were collected from August 5 to 23, 2019, targeting 392 nurses from 14 general hospitals in Gwangju and Jeonnam and t-test, variance analysis, post hoc analysis, Correlations analysis and multi-regression analysis were conducted. In analyzing the differences between demographical and health characteristics and job performance, there were statistically significant differences in age, working years, salary, satisfaction, locations, health status, health education, chronic diseases and depression. In respect to communication perception and job performance of nurses, age of 30 and job satisfaction (moderate satisfaction and dissatisfaction) had a negative effect, locations had a positive effect, and horizontal communication had the greatest effect on job performance. There was a relation between downward, informal and upward communication and job performance, and the determination coefficient was 45.2%. Based on these results, this study suggested that for higher job performance, we should improve working environment, enhance job satisfaction, organize nursing organization culture with active horizontal, downward, informal and upward communication and develop an efficient personnel management system.

  • In 1922, Hongneung forest was established to support the study of Korean forestry. Nowadays the forest also plays a role as urban forest which provides a green space for local people. This paper proposes the better management plan of Hongneung forest based on visitor monitoring. On-site surveys with a structured questionnaire were carried out from August to November in 2014 and total 750 data were analyzed. The survey results are as follows: 1) Visitors were inclusive of all age groups and most of them lived nearby Hongneung forest, 2) Visitors used the forest mainly for recreational purposes and recognized the forest as 'Green space' rather than 'experimental forest', 3) Visitors had great satisfaction from the forest visit and raised the necessity of more environment education and promotion of the program. Based on the results, the following solutions have been suggested: 1) Environment education will help visitors to raise awareness on the importance of Hongneung forest which plays a role as both experimental and urban forest, 2) Systematic visitor monitoring can contribute to efficient visitor management and administration of the areas. In conclusion, it is necessary to establish a visitor management system that enable to achieve a harmonization between nature conservation and recreational demands as well as to improve management of natural resource and service.

  • We describe characteristics of diversity and distribution of oak forests on the Daegok-cheon gorge of the Southeastern Korean Peninsula, the oldest prehistoric site, in view of a sort of food resources of acorns. The $Z{\ddot{u}}rich$-Montpellier School's method was adopted for field investigation on the oak dominant stands. A total of 20 phytosociological $relev\acute{e}s$ composed of 193 taxa were analyzed by syntaxonomy and ecological flora. The Daegok-cheon's oak forests occupied 36.9% ($513,374m^2$) of the surveyed area, and its 99% ($507,677m^2$) was Quercus variabilis and Q. serrata stands. Oak forests of the Daegok-cheon gorge are a kind of regional vegetation type characterizing by the high relative net contribution degree (r-NCD) of Platycarya strobilacea and Sapium japonicum, which are an edaphic type of the xerophilous and thermophilic oak forests. The region of the Daegok-cheon petroglyphs is defined as an ecoregion with rich acorn supply and abundant water resources, and the warmer environment, which attracts prehistoric man.

  • Methicillin-resistant Staphylococcus aureus (MRSA) has been emerging worldwide as one of the most important hospital and community pathogens. At the same time, because of the difficulty in developing chemical synthetic drugs and because of their side-effects, scientists are making more efforts to search for new drugs from plant resources to combat clinical multidrug-resistant microbial infections. Cinnamomum camphora (C. camphora) is a plant of family Lauraceae, and grown Jeju island in South Korea that are used as a drug to treat neurasthenia, epilepsy, cystitis, pyelonephritis, digitalis, cancer, and diabetes mellitus in folk remedies. In this study, antibacterial activites of 80% ethanol extract of C. camphora leaves (CCE) were investigated in combination with antibiotics against clinical isolates of MRSA. The results showed that CCE was determined with MIC and MBC values ranging from 156 to 313 and 313 to $625{\mu}g/ml$, oxacillin from 128 to 256 and 128 to $512{\mu}g/ml$, ampicillin from 4 to 64 and 8 to $128{\mu}g/ml$. The combination of CCE with oxacillin or/and ampicillin were synergistic effect against MRSA 1, 6, 7, 8, 10, 11, 12, 13, and 15/ MRSA 1, 2, 6, and 7.

  • The purpose of this research was to examine the perceptions of CEOs and HR managers on family-friendly management and family-friendly company certification in small- and medium-size businesses. Six CEOs and HR managers participated in focus group interviews. Five themes were identified: provision of various family-friendly workplace policies, recognition of the need for family-friendly management, difficulty introducing family-friendly management and family-friendly workplace policies, willingness to acquire family-friendly company certification, and ways to expand family-friendly management and family-friendly company certification. All participants agreed on the need for family-friendly management and provided different family-friendly workplace policy suggestions for employees regardless of their interests in acquiring family-friendly company certification. However, they also had difficulties introducing family-friendly workplace policies. This finding suggests that different incentives are needed to encourage companies to expand family-friendly workplace policies.

  • This study analyzes the effect of the 2nd pilot test of Tiime of Use (TOU) pricing for Korean households using a two-level electricity demand model. The test, implemented from May to September 2021, was conducted to compare the effects of two TOU pricing rates and the standard rates for households living in apartment and detached house in 7 provinces of Korea. Based on the data on electricity consumption during the test period and during the same period last year of the 1,292 participants and their socio-economic characteristics, this study analyzes (1) whether the relative demand across periods has changed in response to hourly price changes and (2) whether the price responsiveness of daily consumption has changed after the introduction of TOU pricing. The results show that both types of TOU pricing affect neither the relative demand across periods nor the price responsiveness of daily consumption. The reason behind the results could be related to the level of TOU pricing rates and the periodical classification, which were not sufficient to induce changes in the participants' electricity demand patterns.
