Massive Outbreak of Aurelia coerulea in Geoje Bay, Korea

This study was carried out to elucidate the causes of massive outbreaks of Aurelia coerulea in Geoje Bay, Korea, from November 2022 to October 2023. Adult medusae consistently spawn with planulae, and the populations of A. coerulea in Geoje Bay could be categorized into current-year and overwintering populations. The current-year population began with the emergence of ephyrae in February and grew until October, while the overwintering population comprised a mixture of surviving current-year population and additional individuals that joined during the warm season. The size of the planulae are significantly larger than the annual average during the cold season. These results appear to be the energy accumulation of planulae for polyp formation under low water temperatures. Planulae form polyps within a temperature range of 5–25 °C, suggesting the possibility of year-round polyp recruitment. In Geoje Bay, the highest appearance rate of A. coerulea was in April (8.71 ± 12.5 ind. m−3), with ephyrae experiencing higher growth rates up to the young medusa stage. However, from April, a decline in zooplankton biomass resulted in reduced growth rates in adults, indicating that jellyfish growth was primarily regulated by food availability. Additionally, submersed oyster shells in oyster farms served as the main habitat for jellyfish polyps. A. coerulea populations were also characterized by the continuous spawning of planulae throughout the year. In conclusion, this study suggests that stable polyp habitats, abundant food supply during the initial developmental period of the population, and suitable ranges of water temperature were significant factors inducing the massive outbreak of A. coerulea in Geoje Bay, Korea.

The prevalence of IgE positivity, environmental factors, and clinical implications associated with mite species in allergic patients in Taiwan.

Allergic diseases are a growing public health concern with increasing prevalence and severity. Allergens play significant roles in triggering immune responses and the development of allergic reactions. Investigate the presence and clinical significance of dust mites, storage mites, and predatory mite Cheyletus eruditus(Ce) in household environments. A survey of household dust was performed to determine mite occurrence and analyze influencing factors, an analysis of the correlation between mite species and allergic symptoms, and basophil activation triggered by mite allergens. Cross-reactivity between Ce and house dust mites was assessed. The high appearance rate of mite species in households of Taiwan was Dermatophagoides pteronyssinus (Dp) and D. farinae(Df). Environmental factors such as pet keeping, vacuum cleaner usage, air conditioner usage, proximity to the kitchen, cleaning frequency, and protein concentration in beds were shown to influence mite prevalence. The appearance of Dp and Df significantly increased the occurrence of airway and nasal symptoms, while the presence of Ce was strongly correlated with skin symptoms. The activation of basophils and the correlation between specific IgE levels and allergic symptoms in response to Ce exposure were demonstrated. The presence of Ce was associated with elevated levels of allergens in bedding. The IgE adsorption between mite species was demonstrated suggesting cross-reactivity between the Ce and Dp was limited. Presence of Ce is associated with elevated levels of major mite allergens in beddings. Allergenicity of Ce was confirmed by IgE reactivity and basophil activation regarding mite infestation as a potential cause of skin-related allergy.

Biodegradation of Low-Density Polyethylene (LDPE) by Aspergillus niger

The current study focused on the ability of Aspergillus niger to biodegrade low-density polyethylene, while studying some of the factors affecting the biodegradation process, including pH and temperature. Samples were collected from the soil of the waste landfill (sanitary landfill) of Dhi Qar Governorate, located 20 kilometers south of the center of the governorate, and using the dilution method. The genus Aspergillus niger had the highest appearance rate, reaching 100%, as it appeared in all samples, and the colony diameters in the solid medium were calculated. The fungus showed the ability to adapt and grow in the medium containing low-density polyethylene, with the a concentration of (0.1, 0.5, 1)%, and temperature of (15, 25, 35) ᵒC, also pH (2, 4, 6), and the addition of a carbon source of glucose, maltose and a nitrogen source (NH4Cl, NaNo3), the decomposition metabolites and the remaining concentration were identified by using Fourier – transform Infrared Spectroscopy and Gas – Mass Spectroscopy, and later a confirmatory test was conducted to determine the ability of Aspergillus niger to biodegrade low-density polyethylene in the medium of mineral salts.

This study aims to examine the characteristics of landscapes and soundscapes of the islands expressed in elementary school songs located in Sinan-gun, Wando-gun, and Jindo-gun of Jeollanam-do. School songs from 36 schools in Shinan-gun, 36 schools in Wando-gun, and 32 schools in Jindo-gun were investigated. Topography and water have the highest appearance rate of landscape elements, and among elements of topography, mountains and the sea have the highest frequency of appearance. The soundscape elements expressed in school songs are composed of natural sound, artificial sound, human sound, and tranquility, and natural sound has the highest frequency of occurrence. The soundscape elements of nature represent the topographical characteristics of the island region, and the elements of artificial sound, human sound, and tranquility express the life of children or the sound environment of the school. The landscape of the island expressed in the school song sings the appearance and location of the school, the spirit and mind of children, hope for the future, the soul and patriotic spirit of local ancestors, and the beauty of the natural scenery of the island and school in Jeollanam-do. In addition, the identity of the island is expressed by including the history and tradition of gardens and historical sites in the lyrics of school songs.

에너지 정책의 쟁점 관리

This study aims to provide basic data for successful issue management by looking at issues surrounding energy policy macroscopically and collectively and checking changes in issues by period. Text mining techniques, including topic modeling, were used to analyze issues by period and characteristics of each issue, changes in common issues, and connection to the meaning of issues. As a result of the analysis, there were differences in contents, but the “direction” of the policy showed a high rate of appearance at all times, and issues related to nuclear power plants were flowing in two branches along with the direction. In addition, the need for technological innovation is emphasized as a countermeasure, and discussions on regional-led energy transition have begun in earnest in the central government. In addition, it was found that potential issues such as jobs, energy welfare, and conflict exist. In addition, policy suggestions and limitations of the research were described.

Variability in molar crown morphology and cusp wear in two Western chimpanzee populations.

Chimpanzees (Pan troglodytes) possess a relatively generalized molar morphology allowing them to access a wide range of foods. Comparisons of crown and cusp morphology among the four subspecies have suggested relatively large intraspecific variability. Here, we compare molar crown traits and cusp wear of two geographically close populations of Western chimpanzees, P. t. verus, to provide further information on intraspecific dental variability. Micro-CT reconstructions of high-resolution replicas of first and second molars of two Western chimpanzee populations from Ivory Coast (Taï National Park) and Liberia, respectively were used for this study. First, we analyzed projected tooth and cusp 2D areas as well as the occurrence of cusp six (C6) on lower molars. Second, we quantified the molar cusp wear three-dimensionally to infer how the individual cusps alter with advancing wear. Both populations are similar in their molar crown morphology, except for a higher appearance rate of a C6 in Taï chimpanzees. In Taï chimpanzees, lingual cusps of upper molars and buccal cusps of lower molars possess an advanced wear pattern compared to the remaining cusps, while in Liberian chimpanzees this wear gradient is less pronounced. The similar crown morphology between both populations fits with previous descriptions for Western chimpanzees and provides additional data on dental variation within this subspecies. The wear pattern of the Taï chimpanzees are in concordance with their observed tool rather than tooth use to open nuts/seeds, while the Liberian chimpanzees may have consumed hard food items crushed between their molars.

Fuzzy Mamdani for the primary balloon shooter game

Counting is a material that is considered not easy for most elementary school students. Not only from the considerations that are considered challenging but also the influence of the teacher's teaching style which makes bored, and boring is also a problem. In this study, an educational game balloon shooter prime numbers were made. In game design, the Mamdani fuzzy algorithm is applied to calculate the jumrance of balloons with the input variables of remaining_balloon and remaining_time. The application of the Mamdani fuzzy algorithm is considered successful, as evidenced by the high percentage rate of appearance of all balloons, reaching 76.4%.

Seasonal food changes and feeding behaviour adaptations of savanna chimpanzees at Nguye in Ugalla, Tanzania.

We studied the feeding strategies of savanna chimpanzees (Pan troglodytes) at Nguye in Ugalla, Western Tanzania (05°13'S, 30°28'E). Among the driest most open chimpanzee habitats, Ugalla is covered mainly by woodlands. We analysed undigested contents in chimpanzee faeces, and conducted a vegetation survey and a 1-year phenology survey every 2weeks. The fruits of some trees with the highest biomass had high appearance rates in faeces (e.g. Parinari curatellifolia and Diplorhynchus condylocarpon). Herbaceous Aframomum mala fruits grew in large patches in savanna woodland near forest edges along rivers and had the highest appearance frequency over the longest seasonal period in faeces. Other species with higher appearance rates in faeces for long seasonal periods included Grewia mollis at the forest edge and Thespesia garckeana growing on termite mounds at the forest edge. These two tree specieshad low biomass. Thus, savanna chimpanzees fed on some tree foods with higher biomass, herbaceous fruits instead of scarcer tree fruits, and fruits at forest edges and in forests which occupy a small portion of the study area, in addition to woodlands which occupy a large proportion. The forest edge and interior run continuously for long distances along rivers. Forest occupies 2% of this area, but chimpanzees can continuously obtain food by moving along riverine forest. To compensate for fruit scarcity in the non-fruiting (early rainy) season, chimpanzees ate fibrous, low-quality plant parts. Chimpanzees formed smaller parties when ripe fruits and unripe legumes were scarcer. Using these feeding strategies, chimpanzees adapted to savanna woodlands.

Research on the Active Response Functions of ‘en(嗯)’ in Chinese Dialogues with a Focus on the Current Situation and Layouts of Chinese-teaching Textbooks in South Korea

When people learn a second foreign language, they always try to explore rules. If there was a universal golden key, it would save a lot of time and energy on learning methods. The author finds one word among some often used words to respond when watching TV and communicating with others. It is such an inclusive word that people can use to answer in a short time without thinking too hard about the word choice. Through the investigation of the first season of “Ode to Joy”, there seems to be no “en(嗯)” in the subtitle at the bottom of the screen, yet there is quite a high appearance rate in the actual dialogues between the protagonists. Through prior study, it has been discovered that there seems to be very little research on “en” perhaps because the word is too colloquial. Although the probability of discussion in essays is not very high, “en” is indeed necessary for discussion and research from the perspective of the actual usage rate. Based on the research of previous scholars, this research has summarized four types of active response functions of “en”. When replaced with the well-known “shi(是)”, “hao(好)”, “dui(对)”, and “xing(行)”, “en” has been confirmed to be able to replace the above four within the frame of the four active response functions and sometimes bear the brunt. Moreover, the author has sorted and analyzed the three Chinese-teaching textbooks currently used in South Korea, finding that the word “en” rarely appears. Even if it does, it still acts as one of the four functions and there is no explanation about it. It can be considered a pity that such an inclusive response word has not emerged in Chinese-teaching textbooks. It may be more helpful to learners if “en” could be mentioned more.

日本語使用の日韓ビジネスコミュニケーションに おける日本人の問題意識 - 日本人の韓国語能力の差に注目して -

The current study investigated the awareness of issues on Korean-Japanese businesses communication conducted in Japanese language among JC group(Japanese Competent in Korean language) and JI group (Japanese Incompetent in Korean language). Two groups answered the survey with free-form answer. The study found that the awareness of communication problems can be put into two top categories, ‘the prime factors of the problems’ and ‘the opinion about the problems’. Within ‘the prime factors of the problems’, there are four lower categories (1) ‘the prime factor in Korean's consciousness’, (2) ‘the prime factor in Korean's behavior’, (3) ‘the prime factor in Japanese common sense’ and (4) ‘the prime factor in bilateral language competency’, and in ‘the opinion about the problems’ there are two categories as (5) ‘emotional perception about the problems’ and (6) ‘opinion with suggestions about the problems’. In the medium category of (1)(2)(3) and (6), JC group showed higher appearance rate, while in (4) and (5) JI group did. Especially, JI group showed dominantly high appearance in (4), which the range of language competency appears to have a large impact. Furthermore, (5) and ‘emotional’ in (1) has shown JI>JC, which explains that JI has higher level of awareness on emotions and heavier mental burden. Moreover, the lower categories ‘business related’ and ‘business factor’ within (2) and (3) showed JC>JI and ‘business skill’ within (6) was 0% in JI. This further explains that JC group has higher level of awareness on business related factors.

Tillering and Structural Characteristics of Panicum Cultivars in the Brazilian Semiarid Region

Panicum maximum grasses are among the most used in Brazil because they have high forage production potential, nutritional value and adaptation to different climate conditions and in poor soils, which have been improved by the application of dolomitic limestone and nitrogen fertilizers and K2O, P2O5. The aim was to evaluate the tillering capacity and structural characteristics of six cultivars of Panicum maximum in the Brazilian semiarid region. The test was configured as a randomized block design with six treatments—the cultivars Aruana, Massai, Mombaça, Tamani, Tanzânia, and Zuri—and four replications. The studied variables included tiller population dynamics, tiller population density (TPD), appearance rate (ApR), mortality (MorB), tiller survival (SuvP), tiller stability index, height, light interception (LI), forage mass (FM), and morphological constituents. As to the population dynamics of tillers, seven generations were evaluated, and the largest number of tillers was observed in the first generation, regardless of the cultivar. Furthermore, the Massai cultivar demonstrated the highest TPD in all generations. Interaction between the cultivar and evaluation period was noted for ApR: the cultivars Tamani and Tanzânia indicated higher ApR at 122 and 137 days after establishment. The cultivar (P = 0.380) and evaluation period (P = 0.4469) had no effect on SuvP; however, higher MorB was detected in the cultivars Aruana and Tamani compared to Mombaça and Zuri, with intermediate values detected in the other cultivars. The highest FM was observed in the cultivars Massai, Mombaça, and Tamani, as well as in the leaf blade of Massai and Mombaça. The cultivars Massai, Mombaça, Tamani, Tanzânia, and Zuri have the potential to be cultivated in areas with marked water deficit and high temperatures, such as the Brazilian semiarid region. The cultivar Massai has a rapid recovery after a period of water scarcity. The cultivar Aruana is not recommended for use in the Brazilian semiarid region under rainfed conditions.

Population dynamics and structural characteristics of 'Survenola' digit grass subjected to intermittent defoliation strategies

Abstract: The objective of this work was to evaluate the effect of defoliation strategies and insolation periods on the population dynamics and structural characteristics of Digitaria eriantha 'Survenola'. The following four defoliation strategies (DSs) were evaluated: 40/10, 40/20, 50/10, and 50/20 cm (that is, 40 and 50 cm pre-defoliation height, and 10 and 20 cm post-defoliation height), under high- (September to March) and low- (April to August) insolation periods. An experimental randomized complete block design was carried out with five replicates. The accumulation of forage and leaf blade was higher when using the DS 40/20 cm in the higher insolation period. DSs 40/10, 50/10, and 50/20 cm resulted in a higher stem accumulation than DS 40/20 cm. 'Survenola' grass showed a higher appearance rate for basal and aerial tillers using the 40/10 and 40/20 cm strategies, respectively, during the lower insolation period. Greater tiller densities (basal, aerial, and total) were observed in the DS 40/20 cm in the higher insolation period. DS 40/20 cm resulted in a greater tiller renewal. In the DS 40/20 cm, 'Survenola' grass shows the greatest number of defoliation cycles, the highest density of tillers, and the greatest accumulation of forage and leaf blade.

Tillering dynamics of Alexandergrass pasture under nitrogen fertilization

ABSTRACT This study was carried out to evaluate the effect of nitrogen fertilization on tillering dynamics of Alexandergrass (Urochloa plantaginea (Link) Hitch) grazed by beef heifers in a rotational stocking grazing method. The experiment was conducted in a completely randomized design following a repeated measure arrangement, three levels of nitrogen (Zero, 150 and 300kg ha-1) and two area repetition. The classification of tillers into categories (basal and axillary) showed a greater number of basal tillers, due to their higher appearance rate, in the absence of nitrogen fertilization. Nitrogen fertilization promoted higher axillary tiller density. The use of nitrogen promotes the renewal of axillary tillers of Alexandergrass, without compromising the stability of the tiller population.

Physiologically based microenvironment for in vitro neural differentiation of adipose-derived stem cells.

The limited capacity of nervous system to promote a spontaneous regeneration and the high rate of neurodegenerative diseases appearance are keys factors that stimulate researches both for defining the molecular mechanisms of pathophysiology and for evaluating putative strategies to induce neural tissue regeneration. In this latter aspect, the application of stem cells seems to be a promising approach, even if the control of their differentiation and the maintaining of a safe state of proliferation should be troubled. Here, we focus on adipose tissue-derived stem cells and we seek out the recent advances on the promotion of their neural differentiation, performing a critical integration of the basic biology and physiology of adipose tissue-derived stem cells with the functional modifications that the biophysical, biomechanical and biochemical microenvironment induces to cell phenotype. The pre-clinical studies showed that the neural differentiation by cell stimulation with growth factors benefits from the integration with biomaterials and biophysical interaction like microgravity. All these elements have been reported as furnisher of microenvironments with desirable biological, physical and mechanical properties. A critical review of current knowledge is here proposed, underscoring that a real advance toward a stable, safe and controllable adipose stem cells clinical application will derive from a synergic multidisciplinary approach that involves material engineer, basic cell biology, cell and tissue physiology.

Design of new traditional Chinese medicine herbal formulae for treatment of type 2 diabetes mellitus based on network pharmacology

In the present study, 28 Chinese medicinal herbs belonging to traditional Chinese medicine (TCM) for the treatment of type 2 diabetes were selected to explore the application of network pharmacology in developing new Chinese herbal medicine formulae for the treatment of type 2 diabetes mellitus (T2DM). These herbs have the highest appearance rate in the literature, and their compounds are listed. The human protein–protein interaction network and the T2DM disease protein interaction network were constructed. Then, the related algorithm for network topology was used to perform interventions on the interaction network of disease proteins and normal human proteins to test different Chinese herbal medicine compound combinations, according to the information on the interaction of compounds–targets in two databases, namely TarNet and the Medicinal Plants Database. Results of the intervention scores indicate that the method proposed in this study can provide new effective combinations of Chinese herbal medicines for T2DM. Network pharmacology can effectively promote the modernization and development of TCM.

Towards Efficient Online Topic Detection through Automated Bursty Feature Detection from Arabic Twitter Streams

Detecting trending topics or events from Twitter is an active research area. The first step in detecting such topics focuses on efficiently capturing textual features that exhibit an unusual high rate of appearance during a specific timeframe. Previous work in this area has resulted in coining the term “detecting bursty features” to refer to this step. In this paper, TFIDF, entropy, and stream chunking are adapted to investigate a new technique for detecting bursty features from an Arabic Twitter stream. Experimental results comparing bursty features extracted from Twitter streams, to Twitter’s trending Hashtags and headlines from local news agencies during the same time frame from which tweets were collected, show a great deal of overlap indicating that the presented algorithm is capable of detecting meaningful bursty features.

Response of maize hybrids from heterotrophic to autotrophic phase of development in cold conditions

Maize ( Zea mays L.) is a crop of a tropical region with sensitivity to low temperature. This study was conducted to evaluate the performance of experimental maize hybrids in winter months of northern India in field conditions. Data were recorded for survival rate, leaf length and width, seedling height and leaf colour. The analysis of pooled data from 3- leaf stage to 6-leaf stage showed hybrids131023 x 131026 and NS76B x EL-CML-1 as best performers. Hybrids with relatively high leaf appearance rate, less cold injury symptoms showed good level of cold tolerance in terms early seedling growth under cold stress. These secondary traits could be used in selection index for improvement of tropical maize for low temperature adaptation.

Finance Conference Quality and Publication Success: A Conference Ranking

Being subject to time and budget constraints, researchers have to decide on whether to attend academic conferences, and if so, which conferences are most helpful in terms of publication success. Based on acknowledgment information obtained from footnotes of more than 3,000 research articles published in finance journals, we first argue that conference participation constitutes an important factor when publishing research articles in top finance journals. We further track the publication status of more than 4,000 research articles presented at the most popular finance conferences in 2008. Thereby, we arrive at a ranking of 45 finance conferences with the highest appearance rates in top finance journals. In doing so, we provide finance researchers with guidance so they can decide on which conferences to attend.

Morphogenetic and structural characteristics of clones of elephant grass managed under intermittent stocking

This work was carried out to evaluate the morphogenetic and structural characteristics of basal and aerial tillers of two dwarf elephant grass clones (BRS Kurumi and CNPGL 00-1-3) managed under intermittent stocking in six grazing cycles. A completely randomized experimental design with three replications (paddocks) in split-split-plot arrangements was used. The clones were allocated to the plots, tiller classes were assigned to the subplots and grazing cycles to sub subplots. Higher values for basal tillers than aerial tillers were seen for the following characteristics: leaf elongation rate (12.8 and 5.1 cm/tiller/day), leaf appearance rate (0.26 and 0.19 leaves/tiller/day), stem elongation rate (0.38 and 0.16 cm/tiller/day), senescence rate (0.98 and 0.47 cm/tiller/day), total number of leaves (9.3 and 7.1 leaves/ tiller), number of live leaves (7.7 and 5.8 leaves/tiller) and final length of leaf blades (33.5 and 20.0 cm). Phyllochron was lower for basal (4.0 days/leaf) than aerial tillers (5.5 days/leaf). The leaf life span increased with the advance of the grazing cycles, averaging 31.2 days. The tiller density increased with the advance of the grazing cycles showing an average increase of 167% of aerial tillers and 62% of basal tillers for both clones. The morphogenetic and structural characteristics of dwarf clones were influenced jointly by the clones and the availability of the environmental factors of growth during the spring and summer. The high leaf elongation rates, associated with high leaf appearance rate, reveal the potential of high production dry matter of leaves and restoration of leaf area after grazing.
