Impacts of Financial Constraints on Firm Value for KONEX Listed Firms*

Purpose: This study empirically investigates what factors contribute to corporate value in the Korea New Exchange (KONEX) market and determines whether financial constraints contribute any effect on it. Research design, data and methodology : A fixed-effect panel regression model was utilized to analyze financial constraints on firm value for KONEX listed firms through the fiscal period from 2013 to 2020. Results : we find that firms’ research and development, volatility, size, and sales growth give significant impacts to firm value, but the significance and direction are different. In addition, no significant relationship exists between the largest shareholder’s equity ratio and firm value in all models. The debt-to-equity ratio did not show a significant relationship with corporate value. A significant negative relationship was found between R&D and corporate value in the entire sample. Volitility exhibited a positive relationship with corporate value in the entire sample and financially unconstrained companies. Firm size presented a significant negative relationship with company value in all models. Sales growth showed a significant negative relationship with corporate value in financially constrained companies. Conclusions : No difference is found between financially constrained and unconstrained companies in the KONEX market. We can infer that KONEX companies have a large difference with KOSPI or KOSDAQ. Further analysis is needed on the differences among these markets.

Options Méditerranéennes , A n° 88, - Technological Perspectives for Rational Use of Water Resources in the Mediterranean Region Estimating and monitoring seasonal water consumption of olive orchards in a semi-arid region (Morocco) using the Eddy-covariance system

Planning and management of water resources have become a very important issue in arid and semi-arid regions. Accurate measurements of heat and water fluxes are required for optimizing water management and for validating models simulating crop water consumption. For the olive orchard, which is the dominant crop in Mediterranean regions, very little information exists on the exchange of heat and water fluxes between the vegetation and the atmosphere. In the context of SUDMED project, an experimental setup was conceived to monitor seasonal water consumption of olive orchards located near Marrakech, Morocco. For this purpose, an Eddy-Covariance (EC) system, a meteorological station, as well as measurements of soil moisture and temperature were continuously operated during more than one year over an irrigated olive yard, i.e. tall, sparse vegetation. The total annual rainfall and irrigation amount were around 354 and 800 mm respectively. The yearly cumulative evapotranspiration measured from eddy-covariance system was 824 mm. By using the water balance equation, the result showed also that a large quantity of water (around 330 mm) was lost due to deep percolation, infiltration and runoff. This loss is essentially due to the irrigation method (flood) which has an irregular pattern in space and time. On the other hand, the water requirements calculated following the FAO-56 procedure were 920 mm. Although the sum of irrigation and rainfall was greater than ET c , the stress event occurred. Such behaviour can be explained by the fact that the irrigation monitoring is done by observing the physical conditions of the plant which is not sufficient to manage the irrigation. Mots-clés.

Genetic algorithm dynamics in two-well potentials with basins and barrier

The dynamics of a simple genetic algorithm is analyzed on a simple two-well function of unitation. In the infinite population limit, there are phase transitions in the dynamics as the selections strength and crossover probability are changed. In one pahse, the system always evolves to a population consisting only of stirngs from the local well starting from any initial population constining some stirngs from the local well. In the second phase, the genetic algorithm can evolve to a population consisting of strings from the global well, but only if a finite fraction of the initial population was from the global well. In the third phase, the algorithm will evolve to a population consisting of stings from the global well from any initial popluation. For a finite population, the increasing correlation of the population changes the nature of the transition; this is analysed in a weak selection limit where the effects are small. Fluctuation effects, which cause the transition to be smooth in a finite population and are important, are not analyzed here. Comparison with simulations show tht the results are qualititatively correct. There is a phase in which the GA evolves quickly to the global minimum, which can be oredres of magnitude faster than a Monte Carlo algorithm; and another phase in which it evolves to a population dominated by strings from the local well. Quatitiatively, the simulations and theory are not in good agreement due to the simplifications of the theory.
OSTEOID OSTEOMA OF MANDIBLE A RARE CASE REPORT

Osteoid osteoma is a benign primary neoplasm of bone and is three to four times more common than osteoblastoma, a tumour that it histologically resembles. The tumour most commonly occurs in the long bones of the body; however, jaw lesions are very rare. Herein, we report a rare case of osteoid osteoma that presented in the mandible of a 45-year-old female.
Passenger Flow Modeling and Simulation in Transit Stations

Crowd analysis and management is key area of study for transit agencies to maximize operational efficiency and minimize risk. Passenger flow volume, crowd density and walking speed are key features of crowd analytics. This study proposes a generalized Artificial Intelligence (AI)-based crowd analytics model framework for rail transit stations, by analyzing high-density crowd video data. We propose a generalized triple-layer AI-aided methodological framework (named AI-Crowd) for calculating the flow volume, crowd density and walking speed. For the pedestrian detection and tracking layer, the You Only Look Once (YOLO) and Simple Online and Realtime Tracking with a Deep Association Metric (Deep SORT) are integrated to detect and track the dynamic position of each individual. Then, we adjust the original image from the camera to real scale in the camera calibration layer. Next, the calibrated results used by the metric calculation layer to implement a comprehensive calculation of crowd metrics. Several video records from
THE EFFECTS OF CERVICAL CONIZATION PROCEDURE ON FEMALE SEXUAL FUNCTIONS DURING REPRODUCTIVE PERIOD: A PROSPECTIVE STUDY.

Objective: The aim of our study is to investigate the effects of cervical conization on female sexual functions. Material and Methods: Between February and May 2018, a total of 60 patients aged 18-49, sexually active and not in menopause, who were scheduled for cervical conization in the gynecological oncology outpatient clinic were included in the study. One week before and 3 months after conization procedure, sexual functions were measured using FSFI and compared statistically. Statistical significance level was accepted as p <0.05. Results: The mean age of the women was 37.87 ± 6.48 years, and the mean BMI was 25.68 ± 2.67. While 63.3% of the cases before conization had poor sexual function, it was evaluated as poor in 56.7% after conization. There was no significant difference in FSFI total score before and after the procedure (p = 0.222). When the scale subgroups are examined; The decrease in desire (p = 0.049), lubrication (p = 0.050) and orgasm (p = 0.022) scores after conization was statistically significant. Conclusion: Conization procedure applied in the treatment of cervical dysplasia doesn’t affect women’s sexuality. In our study, total FSFI score did not show significant change after conization procedure except desire, orgasm and lubrication domains which have a low score.
Establishment and identi�cation of patient-derived xenograft model for oral squamous cell carcinoma

Objective:The study aim to construct patient-derived xenograft model of oral squamous cell carcinoma and to characterize whether it retained the clinicopathological features of the primary tumor. Materials and methods:The patient-derived xenograft model of oral squamous cell carcinoma was constructed by inoculating the surgically excised oral squamous cell carcinoma tissue under the skin of immunode�cient mice with special treatment, and the P1-P3 generations were used for seeding and identi�cation. The tumor tissues of patient-derived xenograft model were identi�ed by both hematoxylin– eosin staining and immunohistochemistry to to determine the histomorphological consistency and molecular phenotypic similarity between the patient-derived xenograft model and the primary tumor tissues. Results:Hematoxylin–eosin staining and immunohistochemical results showed that the pathological features and molecular phenotypic characteristics of the patient-derived xenograft model of oral squamous cell carcinoma were consistent with the primary tumor tissue. Conclusion:In this study, patient-derived xenograft model of oral squamous cell carcinoma that retains the clinicopathological characteristics of the primary tumor tissue was successfully constructed and can be stably transmitted. mice to retain the characteristics of the primary tumor. Therefore, patient-derived xenograft model combined with drug screening technology to explore new tumor chemotherapy is the key research direction of future tumor treatment. In this study, patient-derived xenograft model of oral squamous cell carcinoma was successfully established, and it was veri�ed by hematoxylin–eosin staining and immunohistochemistry that the constructed patient-derived xenograft model retained the pathological and molecular biological characteristics of primary tumors.
PROCEEDINGS OF THE 25 th International Symposium on Analytical and Environmental Problems

In addition to decades of efforts on making the word sustainable, the achievements are often powerless. Attitudes to business and its social responsibility are continuously evolving. Changing personal attitudes is a key issue in the field. The research question of this paper is whether a change in attitudes is to find among higher education students in recent years in Hungary. The sample consists of 150-150 students from the academic years 2014/2015, 2016/2017 and 2018/2019. The survey asked to rate statements about the characteristics of corporate social responsibility (CSR). However, the results suggest a remarkable change, the statistical analysis confirms only a few of them. General experience of the survey is that the proportion of uncertain respondent (who gave middle-value ratings) has increased. These results show that the change has started, and it proposes that the efforts must be continued.
Managerial Ability, Hedging and Firm Value: A Multiyear Analysis

In this study, we examine the role (impact) of managerial ability on firm value and hedging by constructing an index of managerial ability from his past experiences and education and MA Score index. Using a multi-year data set and managerial ability proxies and controlling for firm and managerial fixed effects, we find that high ability CEOs are associated with higher firm value compared to firms managed by low managerial ability CEOs stressing the importance of CEO General Capital in firm level decisions. However, managerial ability is found not to have a significant impact on firm's hedging decisions. In addition, firm's hedging intensity run by high vs low managerial ability CEOs is documented to be very similar. While these results suggest that CEO managerial ability matters to firm value, it does not have any significant influence on his risk preference measured by derivative hedging.
Directional Dark Matter Search with the NEWSdm experiment

Despite the extensive search for the detection of the dark matter (DM), experiments have yielded null results: they are probing lower and lower cross-section values and touching the so-called neutrino floor. A way to possibly overcome the limitation of the neutrino floor is a directional sensitive approach: one of the most promising techniques for directional detection is nuclear emulsion technology with nanometric resolution. The NEWSdm experiment in the Gran Sasso underground laboratory in Italy is based on a novel nuclear emulsion acting both as the Weakly Interactive Massive Particle (WIMP) target and as the nanometric-accuracy tracking device. This would provide a powerful method of confirming the Galactic origin of the dark matter, thanks to the cutting-edge technology developed to readout sub-nanometric trajectories. Here we discuss the experiment design, its physics potential, the performance achieved in test beam measurements and the near-future plans. After submitting a Letter of Intent, a new facility for emulsion handling was constructed in the Gran Sasso underground laboratory. A Conceptual Design Report was submitted to INFN in Summer 2021.
Influence of Gas Humidity and Gas Flow Rate on Ozone Production and Ethylene Decomposition Using Dielectric Barrier Discharge

—An influence of relative humidity and gas flow rate on O 3 production and ethylene decomposition using dielectric barrier discharge is evaluated. The removal of C 2 H 4 is also investigated in the presence of manganese dioxide (MnO 2 ). In the present experiment, N 2 and O 2 gas mixture is fed into the DBD reactor with a mixing rate of N 2 : O 2 = 8:2 at 5 or 10 L/min gas flow rate. C 2 H 4 gas is diluted by N 2 to 8 ppm. The relative humidity of the gas is adjusted by bubbling gas through water at 0 and 80%RH. The experimental result shows that the O 3 concentration and yield with bubbling are lower than without bubbling and it is almost independent of gas flow rate. The concentration of C 2 H 4 without bubbling is lower than that with bubbling. With bubbling, the concentration of C 2 H 4 with catalyst is higher than that without catalyst.
of Birmingham 3-D P-wave velocity structure of oceanic core complexes at 13°N on the Mid-Atlantic Ridge

20 (cid:4) N and 13 ◦ 30 (cid:4) N, and off axis at 13 ◦ 25 (cid:4) N. These high- Vp features display dipping trends into the deeper crust, consistent with the surface expression of each OCC’s detachment, implying that rocks of the mid-to-lower crust and uppermost mantle within the footwall are juxtaposed against lower Vp material in the hangingwall. The neovolcanic zone of the ridge axis has systematically lower Vp than the surrounding crust at all depths, and is wider between OCCs. On average, throughout the 13 ◦ N region, the crust is ∼ 6 km-thick. However, beneath a deep lava-ﬂoored basin between axial OCCs the crust is thinner and is more characteristically oceanic in layering and velocity–depth structure. Thicker crust at the ridge axis suggests a more magmatic phase of current crustal formation, while modelling of the sparse Moho reﬂections suggests the crust–mantle boundary is a transition zone throughout most of the 13 ◦ N segment. Our results support a model in which OCCs are bounded by independent detachment faults whose dip increases with depth and is variable with azimuth around each OCC, suggesting a geometry and mechanism of faulting that is more complicated than previously thought. The steepness of the northern ﬂank of the 13 ◦ 20 (cid:4) N detachment suggests that it represents a transfer zone between different faulting regimes to the south and north. We propose that individual detachments may not be linked along-axis, and that OCCs act as transfer zones linking areas of normal spreading and detachment faulting. Along ridge variation in magma supply inﬂuences the nature of this detachment faulting. Consequently, not only does magma supply control how detachments rotate and migrate off axis before ﬁnally becoming inactive, but also how, when and where new OCCs are created.
An Integrated Path Formulation Method for Open Domain Question Answering over Knowledge Base

Knowledge Based Question Answering (KBQA) plays a crucial role in the scope of open-domain Question Answering. In prior work, we extract the entity, predict the relation and formulate the Sparql query as a pipeline. The downstream tasks rely on the output of upstream tasks. In COVID 19 Question-answering contest of CCKS2020, we propose an integrated method, which treats all individual tasks in candidate paths generation as a whole, and utilize semantic similarity and re-ranking techniques to select the best path. Our method obtained an F1 score of 85.45% on the final leaderboard.
Electrochemistry Discover the difference Characterization of Inulin - type fructan mixtures

Fructans are polymers consisting of fructose found widely distributed in nature as plant storage carbohydrates. Inulin-type fructans (ITF) are present in many plant species including wheat, onion, bananas, garlic and chicory. Estimates suggest a person consuming an average European diet ingests 3-11 g inulin-type fructans daily [1]. Fructans are a form of dietary fiber as they are not digested in the upper gastrointestinal trac. They can act as an energy source for the gut microbiota and have the potential to promote the growth of specific beneficial bacteria. Furthermore, ITF is increasingly being used as an food additive, for example as a low-caloric sweetener or a texture-improving ingredient of low-fat foods [2].

On some graphotactic rules exhibited by the Old Turkic Irk Bitig text: A case of incipient degraphemization?

On some graphotactic rules exhibited by the Old Turkic Irk Bitig text: A case of incipient degraphemization? Turkic 73–91. The present contribution is aimed at describing some graphotactic rules which, within the Irk Bitig ’s linguistic domain, govern the realization of the grapheme ‹A›. At first we will show that possible models based upon Talat Tekin’s statement (the grapheme ‹A› represents exclusively som e hopefully non-random [-high][-round] [+low][±back] vowels) or upon Marcel Erdal’s explanation (the opposition “grapheme ‹A› versus Ø” represents the opposition [+long] versus [-long]) can be discarded. Eventually, we will observe that the phenomena focused by means of two different mod-el-based analyses—a CVC model-based approach versus a CV model-based one—show (at least, the tendency to adopt) a n-1 set-transcoding system by exhibiting an (incipient) degraphemization of ‹A›, which would become a macro-prosodic marker of the PW rightward boundary. In other words, the grapheme ‹A› ( versus zero) seems to mark the rightward boundary of the PW by exhibiting a stressed syllable nucleus .
Large-field-of-view Chip-scale Talbot-grid-based Fluorescence Microscopy

The fluorescence microscope is one of the most important tools in modern clinical diagnosis and biological science. However, its expense, size and limited field-of-view (FOV) are becoming bottlenecks in key applications such as large-scale phenotyping and low-resource-setting diagnostics. Here we report a low-cost, compact chip-scale fluorescence-imaging platform, termed the Fluorescence Talbot Microscopy (FTM), which utilizes the Talbot self-imaging effect to enable efficient fluorescence imaging over a large and directly-scalable FOV. The FTM prototype has a resolution of 1.2 microns and an FOV of 3.9 mm x 3.5 mm. We demonstrate the imaging capability of FTM on fluorescently labeled breast cancer cells (SK-BR-3) and HEK cells expressing green fluorescent protein.
Effect of inclusion education on the perceptions of sighted school children about the abilities of students living with severe visual impairment and blindness.

Inclusion education was introduced to bridge the gap between access to education and individuals living with disabilities. In developing countries like Ghana, one of the primary reasons for the establishment of inclusion education was to improve the perceptions and attitudes of society from traditionally entrenched derogatory and condescending attitudes towards individuals living with disabilities, perceptions and attitudes which led to the establishment of special schools at the outskirts of towns and cities. Today, inclusion education is widely practiced and although the literature is buoyant with research on the implementation of inclusion education studies, no study has been conducted to identify the influence of inclusion education on the primary recipients, the students. Using structured interview questions exploring perceptions of sighted students in inclusion schools and sighted students in sighted only schools, we describe the differences in perceptions of these students about the abilities of individuals with visual impairment across educational prospects, leadership, participation in social activities, and routine activities. We also compared the perceptions of students living with visual impairment in inclusion schools to those in special schools. The results of the study, analyzed by Braun and Clarkes thematic analysis showed that inclusion education has impacted and influenced positively the perceptions of the sighted students in inclusion schools about the abilities of individuals living with visual impairment compared to the perceptions held by sighted students in sighted only schools. Additionally, this study revealed that the perceptions about the abilities of students living with visual impairment in inclusion schools did not differ from those of the students living with visual impairment in special schools. This study has elucidated the need for public health education programs about the capabilities of individuals with visual impairment to foster and build healthy perceptions about them and enable a more inclusive society.
Topological and symbolic dynamics of the doubling map with a hole

This work motivates the study of open dynamical systems corresponding to the doubling map. In particular, the dynamical properties of the attractor of the doubling map when a symmetric, centred open interval is removed are studied. Using the arithmetical properties of the binary expansion of the points on the boundary of the removed interval, we study properties such as topological transitivity, the specification property and intrinsic ergodicity. The properties of the function that associates to each hole $(a,b)$ the topological entropy of the attractor of the considered dynamical system are also shown. For these purposes, a subshift corresponding to an element of the lexicographic world is associated to each attractor and the mentioned properties are studied symbolically.
