Startup Financing and Capital Structure: A Signaling Approach

조재민,권준엽 한국무역연구원 2022 무역연구 Vol.18 No.1

Purpose Our question is about the entrepreneur’s choice of the capital structure. How does the entrepreneur choose the amount of debt or equity investment in order to send a credible signal about the project value to potential investors? To find the answer to the question, we construct a single-stage signaling game model between a penniless entrepreneur who wants to launch an innovative project and investors. Design/Methodology/Approach We construct a single-stage signaling game model between a penniless entrepreneur who wants to launch an innovative project and debt and equity investors. The entrepreneur strategically chooses a debt level as a signaling device in order to inform his project value to the investors. Observing the amount of debt taken by the entrepreneur, investors evaluate the entrepreneur’s project value and make investment decisions. Findings We derive separating perfect Bayesian equilibria in the signaling game and refine them into a unique equilibrium by invoking the Intuitive Criterion of Cho and Kreps (1987). Then we characterize the refined equilibrium. Research Implications In startup financing, the minimum debt level to make investors perceive the entrepreneur high type is affected by the low type’s expected project value and the ratio of the low type’s equity share to the high type’s.

These experiments were conducted to investigate the properties and characteristics on the pH stability of the purified milk clotting enzyme from Mucor mucede C-7. The results obtained were as follows: 1.The Dependance on pH which effect on milk clotting activity(MCA) of this enzyme was increased along with a decrease in pH of the substrate solution. 2.In pH 6.0 and 3.0 of enzyme solution, MCA was not inactivated by heat treatment for 60min at 35℃ but was inactivated over 50% in pH 6.0 and over 80% in pH 3.0 by heat treatment for 10min at 60℃ respectively, 3.In pH 6.0, Thermo-stability of MCA and PA was showed but in pH 3.0 was not showed. On the other hand, MCA was higher in pH 3.0 then in pH 6.0. 4.pH-stability of MCA was within pH 3.5-5.5 and pH-stability of PA was within pH 3.0-6.0.

This experiments were conducted to investigate the effects of various nutritional sources for the products of the milk clotting enzyme and the results were obtained as follows. 1. The addition of 1% glucose. 0.5% (NH₄)₂SO₄, 0.1% malt extract, and 1.0% NaH₂PO₄ to the wheat bran medium was effective for the production of the milk clotting enxyme. 2. The production of the milk clotting enzyme was makedly increased by the addition of Mallvaine buffer solution mixed these in the wheat bran medium. 3. The maximum enxyme production of the blanded wheat bran medium was reached about 8100 Soxhlet units per gram of wheat bran.

Mucor mucedo C-7이 생산한 정제 응유효소의 특성과 성질(I)

趙載敏 충주대 산업과학기술연구소 1998 産業科學論文集 Vol.6 No.-

These experiments were conducted to investigate the properties and characteristics of the milk clotting enzyme from Mucor mucedo C-7 purified by Amberlite CG-50 column chromatograph and DEAE-Cellulose column chromatograph. The results obtained were as follows : 1.The molecular weight, the isoelectric point, Michalis constant(Km) and Vmax valuese of this purified enzyme were 35,000∼41,000, isoelectric point pH 4.02, 0.17% and 0.34 respectively. 2.Ultraviolet maximum absorption was 275-280nm. 3.The optimum temperature of the proteolytic activity was 60℃ at pH3.0 and the optimum pH of the proteolytic activity was pH3.0 for casein digestion and 4.0 for urea-dena-tured hemoglobin digestion.

Purpose: To demonstrate the incidence and variation of the meniscofemoral ligament in Koreans. Materials and Methods: A total of 100 MR studies of 95 patients were reviewed with special attention to the appearance and incidence of the meniscofemoral ligaments. The ligament of Wrisberg was classified according to proximal insertion: type I, insertion at the posterofemoral condyle ; type II, insertion at the distal portion of the posterior cruciate ligament ; type III, insertion at the distal portion of the posterior cruciate ligament. On T2-weightedimages, the high signal at the meniscal insertion of the meniscofemoral ligament was classified according to itsshape. Results: The ligament o Humprey was observed in 17 cases and the ligament of Wrisberg was in 90:type I in41 cases;type II, 19 cases;type III, in 28 cases;unclassified, in 2 cases. In 77 cases, the cleft with high signal intensity was seen between the meniscofemoral ligament and the posterior cruciate ligament. Conclusion : From ourresults, the incidence of the ligament of Wrisberg on MRI was moe prevelant than the ligament of Humprey. An exact knowledge of the meniscofemoral ligament could be helpful in distinguishing it from pathologic lesions.

Purpose : To evaluate prognosis-related CT findings in hypoxic ischemic encephalopathy. Materials and Methods: For the purpose of prognosis, 28 children with a clinical history and CT findings suggestive of hypoxic ischemicencephalopathy (HIE) were restrospectively reviewed. The diagnostic criteria for HIE, as seen on CT scanning, wereas follows : 1, ventricular collapse ; 2, effacement of cortical sulci ; 3, prominent enhancement of corticalvessels ; 4, poor differentiation of gray and white matter ; 5, reversal sign ; 6, obliteration ofperimesencephalic cistern ; 7, high density on tentorial edge, as seen on precontrast scans ; and 8, low densityin thalamus, brain stem and basal ganglia. On the basis of clinical outcome, we divided the patients into threegroups, as follows : group I(good prognosis) ; group II(neurologic sequelae), and group III(vegetative state orexpire), and among these, compared CT findings. Results : There were thirteen patients in group I, six in groupII, and nine in group III. Ventricular collapse, effacement of cortical sulci, and prominent enhancement ofcortical vessels were noted in all groups, whereas poor differentiation of gray and white matter, reversal sign,obliteration of perimesencephalic cistern, high density on tentorial edge, on precontrast scan, and low density inbrain stem and basal ganglia were observed only in groups II and III. Conclusion : CT findings showed distinctdifferences between groups in whom prognosis was good, and in whom it was poor. An awareness of poor prognostic CTfindings may be clinically helpful in the evaluation of patients with hypoxic ischemic encephalopathy.

23 strains of thermophilic microorganisms were selected from the compost which was collected in the region of JUNG WON GUN for studying the thermostable α-amylase. One Strain which had presented the most remarkable formation ability of α-amylase. among these 23 Strains was selected, identified and the ideal cultural conditions for its formation of α-amylase was investigated. Results obtained were as fallows ; 1) A Strain Used in experiment was microscopically identified asa member of the genus Bacillus. 2) The optimum temperature for the production of α-amylase was revelaed to 65℃ 3) The maximum production of α-amylase by the strain resulted when the initial PH of the medium was adjusted to 7.0, inceubated for 55 hours with the culture of reciprocal shaking. 4) the effective medium for α-amylase formation by the strain was Consisted of 2% Soluble starch, 1.5% Peptone, 0.5% yeast eatract, 0.02% MgSO₄ㆍ7H₂O, 0.3% NaCl, 0.2% (NH₄)₂HPO₄.

趙載敏 忠州大學校 1982 한국교통대학교 논문집 Vol.15 No.1

Oxidative changes of the doughnut lipids were studied under three experimental storage conditions. Doughnut was 1) exposed to fluorescent light irradiation at 15℃ 2) incubated in the dark at 40℃ and 3) irradiated with sunlight. In the study, changes in acid values, peroxide values, fatty acid composition an iodine value were determined with the lipids extracted from the doughnut samples in intervals for a period of 5 weeks. Acid values, peroxide values of the samples under fluorescent light irradiation and 40℃ incubation increased slightly during storage, while a sharp increase of these values were noticed with the samples of sunlight irradiation. In the event of sunlight irradiation the content of linoleic acid and linolenic acid decreased, on the other hand the content of palmitic acid and stearic acid increased.

Post-transplantation lymphoproliferative disorder occurs in transplant recipients in whom immunosuppressive therapy has compromised the immune system. In patients who have undergone transplants, suppressor T lymphocyte function is suppressed, leading to unbridled B lymphocyte proliferation. We encountered a case with post-transplantation lymphoproliferative disorder which manifested as a focal hepatic mass in transplanted liver. This mass was isoechoic, with a peripheral hypoechoic halo on ultrasonogram, while on all three phases of helical CT scan, low attenuation without contrast enhancement was seen.
