Under the assumption that firms’ foreign currency derivative usage depends on corporate governance and outside blockholders, this paper examines the impact of corporate governance on foreign currency derivative usage. Using non-financial Korean firms from 2002 to 2007, the results showed that there exists inverted U-shape relationship between major shareholders ownership and foreign currency derivative usage. This shows that when major shareholders ownership is low, major shareholders want to decrease risk, but when it’s high, major shareholders want to increase risk. Second, there are negative relationship between domestic blockholders ownership and derivative usage. This relationship also holds when foreign blockholders ownership was used. This showed that domestic as well as foreign blockholders want to use derivatives to maximize profits. Third, the significance of the relationship between blockholders ownership and derivative usage was different if fair market value or contract value was used as derivative usage. This paper finds that there exists different purpose of foreign derivative usage between major shareholders and blockholders, domestic and foreign blockholders have same perspectives on derivative usage. 본 연구는 기업지배구조에 따라 파생상품사용확률과 사용정도로 나타나는 기업의 헤징정책이 변화할 것이며, 이러한 기업지배구조의 영향은 외부대주주의 존재에 따라 달라질 것이라는 가정 하에 실증분석을 실시하였다. 표본기간은 2002년부터 2007년까지이며 비금융업 12월 결산법인으로 상장기업을 대상으로 토빗분석을 실시하였다. 분석결과, 첫째, 대주주지분율과 파생상품사용정도 간의 관계는 지분이 낮은 수준에서는 정(+)의 관계가, 지분이 높은 수준에서는 부(-)의 관계가 나타나는 역U자형의 관계임이 확인되었다. 이는 대주주지분이 낮은 수준에서는 위험회피성향이 높음을, 대주주지분이 높은 수준에서는 위험회피성향이 낮음을 의미한다. 둘째, 공정가액을 기준으로 할 경우, 국내외부대주주 지분이 증가할수록 파생상품사용은 부(-)의 관계가 나타났으며, 계약가액을 기준으로 할 경우, 외국인 외부대주주 지분과 파생상품사용 간에 부(-)의 관계가 나타났다. 이는 국내외 외부대주주가 존재할 경우 위험수용 수준을 극대화하려는 경향이 있음을 확인하였다. 본 연구는 기업지배 구조와 파생상품사용으로 대표되는 기업의 헤징정책간 관계를 파악하였으며 파생상품사용에 있어 대주주와 외부대주주간 차이가 있음을 확인하였다.

Stress and trauma research has traditionally focused on the negative sequela of adversity. Recently, research has begun to focus on positive outcomes, specifically posttraumatic growth (PTG)–“positive change experienced as a result of the struggle with trauma”–which emphasizes the transformative potential of one’s experiences with highly stressful events and circumstances. For evaluation of PTG, resilience is very important. Resilience refers to a person’s ability to successfully adapt to acute stress, trauma or more chronic forms of adversity, maintaining psychological well-being. This article introduces several measurement scales for assessment of PTG and resilience. In addition, we suggest psychological techniques for facilitating PTG focusing on the relationship with adaptation after trauma. Finally, we discuss the applicability of a therapeutic approach for PTG in clinical practice. The systemic review of this article will provide further directions for PTG and resilience.

The purpose of this study was to investigate the displacements of cast framework by torch soldering and electric soldering techniques. Specimen had two cylinders and connecting bar that had sectioned with 0.3mm gap at mid point. 10 of total specimens were divided into two groups. In torch soldered group, soldering investment block was made and conventional torch solder-ing procedure was carried out. In electric soldered group, electric soldering was carried out on the master cast without soldering investment block by using electric soldering machine(Dentapunkt DP 7, Kulzer, Germany) After soldering procedure, three dimensional coordinates of two centroids of each cylinder were measured by three dimensional coordinate measuring machine. The intercentroidal displacement and global displacement were calculated and then, these values were compared and evaluated. The results were obtained as follows: 1. Intercentroidal distances of specimens decreased after both soldering procedures, and the decrease in intercentroidal distance was greater for torch soldered group than for electric soldered group 2. Global displacements of torch soldered group were greater than those of electric soldered group.

전이성 신세포암의 치료에서 전이병소 절제술 및 면역화학요법을 이용한 복합요법의 의의

전상원,전승현,장성구 대한비뇨의학회 2008 Investigative and Clinical Urology Vol.49 No.1

Purpose: One third of renal cell caricinoma(RCC) patients present with metastatic disease and 20-40% of these patients who undergo nephrectomy for clinically localized RCC will develop metastases. Eventually, the number of those patients who develop metastatic disease will increase to 30- 50%. The aim of this study is to compare the efficacy and survival rate in relation to the time of performing metastasectomy and immnuochemotherapy. Materials and Methods: We retrospectively enrolled 12 patients who had undergone radical nephrectomy, immunochemotherapy and metastasectomy between 1998 and 2007. The patients were subdivided into two groups. Group 1 included the patients who received radical nephrectomy, metastasectomy and immunochemotherapy altogether. Group 2 included the patients who developed metachronous metastases during follow-up after radical nephrectomy and so they then underwent metastasectomy and immunochemotherapy. We compared the survival rates between the two groups. Results: The sites of initial metastasis were found to be 8 cases of lung metastasis, 2 of bone metastasis, 1 of brain metastasis and 1 of colon metastasis. The 5-year survival rate of the 5 patients from group 1 was 37.5%. In group 2, the 5-year survival rate of the 7 patients was 71.4% and the disease-free mean interval between primary resection of the kidney and metastasectomy was 36.43±7.62 months. Statistically, there was no significant difference of survival rates between the two groups. Conclusions: The results of this study suggest that metastasectomy followed by radical nephrectomy results in a longer survival time for the patients with metastatic cancer than that of patient that undergo radical nephretomy, metastasectomy and immunotherapy at the same time. We can recommend metastasetomy any time for the RCC patients who have technical resectable metastases with possibly positive prognostic factors and a good functional condition.

Dystrophic Calcification and Stone Formation on the Entire Bladder Neck After Potassium-titanyl Phosphate Laser Vaporization for the Prostate: A Case Report

전상원,박용구,장성구 대한의학회 2009 Journal of Korean medical science Vol.24 No.4

Dystrophic calcification can be defined as a calcification that occurs in degenerated or necrotic tissue. It is associated with multiple clinical conditions, such as collagen vascular diseases. It involves the deposition of calcium in soft tissues despite no generalized disturbance in the calcium or phosphorus metabolism, and this is often seen at sites of previous inflammation or damage. Potassium-titanyl phosphate (KTP) laser vaporization of the prostate is safe and relatively bloodless procedure that results in a shorter catheterization, immediate symptomatic improvement, and less severe postoperative irritative symptoms. However, longer follow-up studies or reports about complications are lacking. Here in we report a case of dystrophic calcification and stone formation on the entire bladder neck after performing KTP laser vaporization of benign prostate hyperplasia. That was treated by lithotripsy and transurethral resection.

This study is a descriptive research study conducted to understand the effects of hospital nurses' COVID-19 risk perception, media dependence, government trust, resilience, and Socio-psychological stress on COVID-19 prevention behavior. Data were collected from 200 nurses at university hospitals, and the collected data were analyzed using descriptive statistics, t-test, Pearson's correlation analysis, ANOVA, and multiple regression analysis using the SPSS 24.0 program. The average age of the subjects was 29.8 years old, the hospital experience was 6.6 years, and the prevention of COVID-19 was high with 4.3 points. COVID-19 prevention behavior showed positive correlation with COVID-19 risk perception, resilience, and media dependence and negative correlation with socio-psychological stress. Factors influencing COVID-19 prevention behavior were COVID-19 risk perception, resilience, socio-psychological stress, and media dependence. To ensure that hospital nurses' COVID-19 prevention behaviors can be continued, it is necessary to appropriately manage COVID-19 risk perception and media dependence, and to develop and apply an intervention program to strengthen resilience and reduce socio-psychological stress. 본 연구는 병원간호사의 COVID-19 위험인식, 미디어 의존, 정부신뢰, 회복탄력성과 사회심리적 스트레스가 COVID-19 예방행위에 미치는 영향을 파악하고자 수행된 서술적 조사연구이다. 대학병원 간호사 200명을 대상으로 자료수집을 하였고, 수집된 자료는 SPSS 24.0 프로그램을 활용하여 기술통계, t-test, Pearson’s 상관관계 분석, ANOVA, 다중회귀분석으로 분석하였다. 대상자의 평균연령은 29.8세, 병원 경력은 6.6년이었고, COVID-19 예방행위는 4.3점으로 높은 편이었다.

ZnO:Al(AZO) films prepared by rf magnetron sputtering on glass substrate and textured by post-deposition chemical etching were applied as front contact and back reflectors for ${\mu}c$-Si:H thin film solar cells. For the front transparent electrode contact, AZO films were prepared at various working pressures and substrate temperature and then were chemically etched in diluted HCl(1%). The front AZO films deposited at low working pressure(1 mTorr) and low temperature ($240^{\circ}C$) exhibited uniform and high transmittance ($\geq$80%) and excellent electrical properties. The solar cells were optimized in terms of optical and electrical properties to demonstrate a high short-circuit current.
