We have presented detected molecules, atoms, radicals, ions, and dimers in the atmospheres of planets and comets from Earth-based and spaceborne observatories during the last 3 decades. We have reviewed spectroscopic studies on the auroral emissions and air glows of the giant planets, and briefly summarized spectroscopic observations of dimers in the atmospheres of the giant planets and Titan. In particular, we highlighted the recent detections of new molecular emissions and absorptions in the spectra of the giant planets, Titan, and recent bright comets from spaceborne or ground-based observatories. We also reviewed current models and theories of the origin and evolution of the solar system, and implications of isotopic ratios in these atmospheres.

Purpose: To evaluate if the presence of pathologic myopia could affect the result of macular hole surgery. Methods: This study was a retrospective comparison of the results of macular hole surgery between a pathologic myopia group (11 eyes) and a non-pathologic myopia group (14 eyes). All patients had undergone PPV, ILM peeling and C3F8 (20%) gas temponade. BCVA, IOP and OCT findings were evaluated preoperatively and at 6 months after surgery. Postoperative BCVA, IOP and macular hole closure were compared between each groups. Results: The only statistically significant preoperative parameter between the groups was axial length (p < 0.001). Postoperative BCVA was lower in the pathologic myopia group, but the difference was not statistically significant. The rate of macular hole closure was statistically significant higher in the non-pathologic myopia group (p < 0.001). Conclusions: The presence of pathologic myopia may negatively affect the result of macular hole surgery.

Purpose: We report a case of post‐traumatic bilateral serous retinal detachment that resolved spontaneously within a month. Case summary: An 8-year-old male patient presented with post-traumatic bilateral serous retinal detachment and decreased visual acuity. We did not perform any specific treatment. Best corrected visual acuity (BCVA), fluorescein angiography (FA), optical coherence tomography (OCT), and slit lamp examination were used. Conclusions: After 1 month, the patient’s BCVA improved to 1.0 in both eyes, and serous retinal detachment resolved; FA findings and OCT findings were nearly normal.

부채가 기업가치에 미치는 영향은 기업의 자본구조와 관련하여 오랫동안 연구되어 온 영역이다. 하지만 그 실증적 결과는 우리가 이해하고 있는 부채 관련 이론, 즉 상충관계이론(trade-off theory)과 자본조달순서이론(pecking order theory)의 예측과는 거리가 있는 경우가 있다. 이는 여전히 부채가 기업가치에 미치는 영향에 대해서 보다 심층적으로 고찰할 필요가 있음을 의미하기도 한다. 본 연구에서는 기존의 연구들이 부채가 기업가치에 미치는 메커니즘을 설명함에 있어서 부채수준과 부채증감분을 혼용하고 있음을 밝히고 이 둘이 기업가치에 어떤 차별적 효과를 보이는지 제시하고자 한다. 먼저 부채수준은 자본구조의 상태를 의미하는 것으로, 자본구조 내에 부채가 많을 경우 파산위험이 커지게 된다. 이는 결국 투자자에게는 좋지 않은 영향을 주어 기업가치에 악영향을 미칠 것이다. 한편 부채증감분은 자본구조를 결정하는 기업의 행위를 보여는 것으로 부채증감분이 크다는 것은 기업이 저평가되어 성장의 기회가 있는 것으로 평가되어 기업가치에 긍정적 영향을 줄 수 있음을 의미한다. 이러한 주장은 미국의 5,305개 상장기업을 대상으로 부채수준과 부채증감분의 토빈 q 비율(Tobin’s q)간의 상이한 관계를 통해서 검증하였다. 이는 상충관계 이론으로도 설명이 제한적이고 자본조달순서이론으로도설명이 불완전한 부분이 있는, 부채가 기업가치에 미치는 영향을 새로운 각도로 접근할 필요가 있음을 시사한다. This study postulates that neither trade-off theory nor pecking order theory is perfect to explain the effect of debt on firm valuation. Illuminating that the prior literature did not distinguish between debt levels (i.e. a state of capital structure) and debt financing (i.e. an action for capital structure), this study specifies the impacts of debt level and debt financing on firm valuation. The debt level signifies how a firm’s capital structure is characterized with debts. Since the dominance of debts in the capital structure indicates how likely the firm has the bankruptcy risks, the higher debt level will make the firm valuation more detrimental. Meanwhile the debt financing indicates how a firm constructs its capital structure by adding debts. As a means of investments, debt financing can be strategically interpreted from the market. As such, debt financing can bring more positive evaluation of the firm and it can enhance firm valuation. These divergent impacts of debt level and debt financing on firm valuation are examined using COMPUSTAT database of 3,505 U. S. listed firms ranging from 1962 to 2010. I employed the fixed-effects models to estimate Tobin’s q with respect to the debt-equity ratio (representing the debt level) and the change in debt-equity ratio (representing the debt financing). The results show that debt levels show a negative impact on Tobin’s q but debt financing has a positive effect. As these findings reveal, we can specify the previously-inconclusive impacts of debts on firm valuation by elaborating the different meanings of debt levels and debt financing.

개에서 자가 부분 간 이식술전후 동맥혈의 KBR ( Ketone Body Ratio ) 측정과 이식 간의 초기 기능부전 지표로서의 상관관계에 관한 연구

N/A Living-related segmental liver transplantation is now accepted as a method of liver transplantatior in pediatric group. But if graft failure occurs, mortality is high. Hence the early prediction of graft failure may contribute to the improvement of the chance of survival. The ketone bodies (acetoacetate, B-hydroxybutyrate) are known to be produced in the hepatic mitochondria. KBR (ketone body ratio) is a ratio of acetoacetate/B-hydroxybutyrate, which ref1ects the NAD+/NADH, i.e. oxidoreduction state of NAD of hepatic mitochondria. Because the viability of grafted liver is ultimately depeadant on the oxidoreduction potential of hepatic mitochondria, KBR might reflect the viability of grafted liver. The purpose of this experiment is to study whether KBR is a useful indicator of initial grat failure after liver transplantation. The experiment consisted of ten autologous left lobe liver transplants in dogs. The arterial blood was taken at preoperative period, anhepatic stage, reperfusion-15 minutes, 1 hour, 3 hour, 6 hour anl daily during their survival, and then KBR was calculated by ketone body concentration. The result of KBR measurement was as follows; it was 1.16+-0.33 at preoperative period, and abruptly decreased to 0.46+- 0.21 at anhepatic stage, and recovered to various levels according to initial graft function after reperfusion. To evaluate the initial graft function, the dogs were divided into two groups. A group (n=3) had KBR below 0.7 at reperfusion 1 hour, and B group (n=7) above 1.0. In group A, all of them showed early graft failure and died within 12 hours postoperatively. KBR changes in group A were as follows; it was 1.16 at preoperative period, and decreased to 0.25 at anhepatic stage, and recorded 0.69, 0.54, 0.61, 0.29 at reperfusion-15 min, 1 hour, 3 hour, 6 hour respectively. It never recovered above 0.7 at any period after reperfusion. In group B. they showed good early-graft function with survival of 16 hours to 8 days and died of other causes, ln group B, preoperative KBR was 1.16, and decreased to 0.54 at anhepatic stage, but promptly recovered to 0.95 at reperfusion-15 minute, 1.32 at 1 hour. It slightly decreased to 0.83 at 1 hour but maintained above 1.0 after 6 hour. In conclusion, the decreased KBR at anhepatic stage should promptly recover after reperfusion for the graft viability, and the value below 0.7 of KBR after reperfusion-1 hour represents the early graft failure, and above 1.0 of KBR represents good functioning graft. The KBR is a useful indicator of early graft function in canine autologous segmental liver transplantation, and it is assumed that KBR is further applicable on canine and human allogenic segmental liver transplantation.

Where Does Knowledge Integration Come From?
Sang-Joon Kim(김상준) 한국경영학회 2016 한국경영학회 통합학술발표논문집 Vol.2016 No.8
This study provides a new perspective to understanding knowledge integration processes, which argues that each individual has his/her own structure of behavior that affects his/her adoption of new ideas. Based on the phenomenological perspective which presumes that an individual’s behavior is culturally constructed in the life-cycle; it is not atomized, but rather structured as a coordinated system within a person, this study postulates that the structure of behavior plays a critical role in facilitating the adoption of new ideas. The structure of behavior, defined as the self-coordination of existing behaviors drawn from multiple institutionalized rules, is specified as three distinctive structural properties: behavioral connectedness, behavioral fragmentation, and triangular mutuality. These structural properties consistently indicate how cohesive an individual’s behaviors are interconnected with respect to a new idea, and such internal fit among institutionalized behaviors can increase the likelihood of adopting a new idea. The theoretical formulation of the structure of behavior also suggests that an individual’s behavior is repeatedly coordinated and reorganized in response to a new idea, and the structure of behavior can be an important micro-foundational explanation on knowledge integration processes.
