In order to improve the optical applications of amorphous KNbO? thinfilms, we deposited KNbO? on glass substrate by rf magnetron sputtering method. The sample was prepared by a number of different conditions, such as composition mole percent ratio of target, calcine temperature and rf power. And then we measured the refractive indices and electrooptic coefficients by measuring of induce phase difference of light from electrooptic effect of amorphous KNbO? thinfilms. We obtained the value of refractive indices 2.130 ~ 2.213 at 632.8nm and electrooptic codefficients γ= 0.2476 × 10? ~ 1.0716 × 10?m/V.

Objective The Reading the Mind in the Eyes Test (RMET) was developed by using Caucasian eyes, which may not be appropriate to be used in Korean. The aims of the present study were 1) to develop a Korean version of the RMET (K-RMET) by using Korean eye stimuli and 2) to examine the psychometric properties of the Korean-translated version of the RMET and the K-RMET. Methods Thirty-six photographs of Korean eyes were selected. A total of 196 (101 females) healthy subjects were asked to take the Ko-rean-translated version of the RMET and K-RMET. To assess internal consistency reliability, Cronbach’s alpha coefficients were comput-ed, and test–retest reliability was assessed by the intraclass correlation coefficient (ICC) and Bland-Altman plots. Confirmatory factor analysis (CFA) and item analysis were also conducted. Results Internal consistency, measured by Cronbach’s alpha, was 0.542 for the Korean-translated version of the RMET, and 0.540 for the K-RMET. Test–retest reliability (n=25), measured by the ICC, was 0.787 for the Korean-translated version of the RMET, and 0.758 for the K-RMET. In CFA, the assumed single and 3-factor model fit indices were not good in the both types of RMETs. There was difficulty in discrimination in nine items of the Korean-translated version of the RMET and 10 items of the K-RMET. Conclusion The psychometric properties of both the Korean-translated version of the RMET and the K-RMET are acceptable. Both tests are applicable to the clinical population, as well as the general population in Korea. Psychiatry Investig 2021;18(4):295-303

Objectives: The present study evaluated the effects of job stress, including organisational system to self-rated depression through a panel study of male municipal firefighters in the Republic of Korea. Methods: A panel of 186 municipal firefighters reported self-rated depressive symptoms according to the Beck Depression Inventory (BDI). The effects of job stress were evaluated using the Korea Occupational Stress Scale, taken one year earlier and classified by the median value. Panel members were classified into Depression or Control groups according to BDI scores, with a cut-off level of ‘over mild depression’ in a follow-up survey. Results: The Depression group included 17 (9.1%) workers. Firefighters who scored high on occupational system had an 8.3 times greater risk of being assigned to the Depression group than those who had not (adjusted odds ratio [OR] = 8.03, 95% confidence interval (CI) = [1.73?37.22]). In contrast, job stress from a ‘difficult physical environment’ revealed negative risks related to being classified in the Depression group (AOR = 0.20, 95% CI = [0.04?0.92]). Conclusions: Although the healthy worker effect may be involved, job stress based on perceptions of organisational system was a strong risk factor for depression. A comprehensive approach should be considered that encompasses social issues when assessing or mental health in high-risk groups, as well as the practical issue of physiochemical hazards.

None of these can be accomplished unless financial constraints are built into the process from the very start. In the budget process, the future is inherently uncertain, and the more so the longer the period considered. The general trade-off is between policy relevance and certainty.

Multi-year planning and forecasting serves to increase the fiscal discipline by setting overall fiscal policy objectives, showing the medium costs of continuing existing policies through baseline projections, and illuminating the full-year budget implications of decisions in following budgets. In this paper, we study to improve the effectiveness of medium-term fiscal plan in the perspective of multi-year budget system. We study the role of multi-year budget system in the framework of annual budget system, and analyze how to complement the shortcomings of annual budget system. Under the given legal framework, we consider the introduction of pre-budget system to improve the possibilities of fiscal forecasting and transparency, and suggest the enforcement of continuing expenditure system in the fiscal programs. Through the introduction of continuing expenditure system, Seoul Metropolitan government can save considerable amount of budget in the public investment programs and expend the budget efficiently by reducing the constructing period.

Pulmonary Embolism Detected in the General Ward after Operation: A Case Report

Se Hyun Lew,Jong Hun Jun,Hee Koo Yoo,Yong Ho Kim Korean Society of Critical Care Medicine 2004 Acute and Critical Care Vol.19 No.1

Pulmonary embolism is a common medical complication following major orthopedic procedures of the lower extremities and a leading cause of morbidity and mortality. However, the clinical manifestations of pulmonary embolism are nonspecific and it may be difficult to diagnose. An 82 years old female with severe restrictive pulmonary disease received the elective operation for the fracture of left femur neck under combined spinal-epidural anesthesia. During the operation, we sometimes gave her oxygen via face mask and maintained oxygen saturation of more than 80% which was measured by a pulse oxymeter. The operation and anesthesia was performed uneventfully. On the seventh postoperative day, she showed tachycardia suddenly and cardiac arrest later on the electrocardiogram. After cardiopulmonary resuscitation, she was transferred to intensive care unit and checked by a computed tomography and echocardiography. She was diagnosed with pulmonary embolism and deep vein thrombosis and treated with heparin and urokinase. But she did not improve and died.

Purpose: The neutrophil gelatinase-associated lipocalin (NGAL) level following cardiac surgery is useful for predicting acute kidney damage. However, there is insufficient conclusive evidence as to whether NGAL can be used to predict subclinical acute kidney injury following non-cardiac surgery. Methods: We measured serum NGAL and creatinine levels in 41 patients following non-cardiac surgery, and used the definition of sublinical AKI with NGAL Results: The study included a total of 41 patients. The mean age was 64.65 ± 17.09 years. The value of serum creatinine was decreased 4 hours after surgery and increased 12 hours after surgery. The serum NGAL decreased after 4 hours after surgery and continuedto decrease after 12 hours after surgery. The incidence of subclinical acute kidney injury determined by the 4 hour serum NGAL level was 16 (39.0%), and the incidence of serum creatinine elevation over CV was 8 (19.5%). The incidence of subclinical acute kidney injury determined by the 12 hour serum NGAL level was 11(26.8%), and the incidence of serum creatinine over CV was 15 (36.5%). The elevation of NGAL over CV was more rapid than the serum creatinine 4 hours after surgery. For a patient with subclinical acute kidney injury, we tested the serum creatinine 6 and 12 months after surgery. The incidence of serum creatinine elevation was higher in patients with subclinical acute kidney injury compared to patients without injury, suggesting a clinical implication. Conclusions: We verified the usefulness of the serum NGAL level as a predictive factor for long-term renal prognosis in patient with subclinical AKI after non-cardiac surgery. Keywords: NGAL; Acute kidney injury; Predictive factor; Non-cardiac surgery; Creatinine

유방의 과립세포 종양은 드물게 발생하는 양성 종양으로 말초 신경의 신경섬유초 세포에서 기원하는 것으로 알려져 있다. 과립세포종양의 임상적, 영상의학적 소견은 유방의 악성 종양 소견과 유사하여 양성 종양임에도 불구하고 악성 종양으로 오인되기 쉽다. 저자들은 갑상선 기능 항진증으로 추적 관찰 중인 54세 여자의 우측 유방에서 중심 침생검과 면역조직화학 염색으로 진단된 과립세포종양 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Granular cell tumor (GCT) of the breast is an uncommon, usually benign tumor originating from Schwann cells of peripheral nerves. Clinical and radiological findings of GCTs are similar to those of malignant tumors, and GCTs of the breast are often confused with breast cancer clinically or radiologically. We experienced 1 case of GCT diagnosed by core needle biopsy and immunohistochemical staining in the right breast of 54-year-old woman with Graves`s disease and report the case with a review of the literature.
