Polycrystalline silicon (poly-Si) thin film transistors (TFTs) might be fabricated on the mica substrate and transferred to a flexible plastic substrate because mica can be easily cleaved into a thin layer. To overcome the adhesion and stress problem between poly-Si film and mica substrate, a buffer layer consisting of $SiO_x/Ta/Ti$ three layers has been developed. The $SiO_x$ layer is for electrical isolation, the Ti layer is for adhesion of $SiO_{x}$ and mica. and Ta is for stress relief between $SiO_x$ and Ti. A TFT was fabricated on the mica substrate by a conventional Si process and was successfully transferred to a plastic substrate.

This study analyzed the data of 102 athletes who participated in National Sports festival in May, 2015 in order to investigate the gymnastics referee’s decision which female gymnasts perceive and moderating effects of exercise commitment in relation to intention to decide dropout. Questionnaires developed and used in previous studies were appropriately modified and supplemented as the measuring instrument in accordance with the research purposes and its validity and reliability was verified using the SPSS18.0 statistical program. Firstly, the results of the analysis of the difference by the group the ybelonged to showed that gymnasts in the adult and university division with a lot of exercise experience perceived a low level of exercise commitment, on the other hand gymnasts in middle school division a high level. Meanwhile, gymnasts in the university division perceived a high level of intention to decide dropout while those in the middle school division a low level. And, the results of the analysis of the correlation between measurement variables showed that referee’s decision had a positive(+) correlation with exercise commitment while referee’s decision and exercise commitment had a negative(-) correlation with intention to decide dropout. Finally, the results of the analysis of the moderating effects of exercise commitment showed that at high level of cognitive commitment and behavioral commitment, moderating effect to prevent intention to decide dropout was verified.

Purpose: Quantification of the dialysis dose is an essential element in the management of hemodialysis. The author investigates the reliability of hemodialysis adequacy measured by ionic dialysance (Online clearance monitoring(R), OCM). Because OCM is a non-invasive and instantly accessible method, it could be replaced Kt/V derived from single-pool variable volume urea kinetic model (UKM). Methods: Kt/V using UKM and OCM were measured simultaneously in 51 patients who have received hemodialysis therapy via arteriovenous fistula. The analysis of the data collected from 186 hemodialysis sessions were performed. Results: Kt/V of conventional hemodialysis, high efficiency hemodialysis and hemodiafiltration measured by UKM were 1.39±0.24, 1.41±0.23 and 1.53±0.17, and by OCM were 1.24±0.17, 1.26±0.19 and 1.39±0.19, respectively. The data of UKM were significantly higher than those of OCM (p=0.00). Also, there were strong positive correlations between UKM and OCM in hemodialysis (r=0.80, p=0.00), high efficiency hemodialysis (r=0.65, p=0.00) and hemodiafiltration (r=0.67, p=0.00). Conclusion: The Kt/V using OCM measured by ionic dialysance provided slightly lower data than that of UKM derived from single-pool variable volume urea kinetic model, but it may be a reliable test to evaluate dialysis adequacy in conventional hemodialysis, high efficiency hemodialysis and hemodiafiltration.

1. CONTENTS (1) RESEARCH OBJECTIVES Recently government set up a new plan for stabilizing real estate market in Korea from the perspective of real estate tax structure reform. But, considering the fact the tax instrument has a wide variety of effects in allocation resources in the market, we must find out the expected results and the direction of the market movement in advance. And, to achieve the policy goal, it is more important to design an atmosphere of tax compliance rather than to control the market behavior of economic agents. In this way, I try to see the matter through economic incentive mechanism in the market, and finally, I reached a conclusion. (2) RESEARCH METHOD I adopted Law and Economics perspective into the real estate tax structure. I tried to explain the fact that the policy mechanism is worse in efficiency than market mechanism through mechanism concept. (3) RESEARCH RESULTS From the perspective of Law and Economics, by using sigmaplot, value of real estate asset is inflluenced by tax attributes, especially, the spread between capitla gain tax and withholding tax, which remains leverage incentives from debt financing as investor. Thus, there still leaves reeal estate investors who gather money by bank loan as though the tax policy changes. And, from the legal perspectives,incumbent real estate tax does not breach the constitutional law. 2. RESULTS To promote the function of real estate market mechanism, firstly, transaction tax(acquiring tax, stamp tax) should be lowered by far. Second, property tax can be raised on condition that the tax base is reasonably designed. And finally, capital gain tax should be lowered to accelerating the function of the real estate market. 3. KEY WORDS real estate tax reform, capital gain tax, income tax, realization principle

목적: 심박수는 운동, 호흡, 대사변화 그리고 육체적 또는 정신적 긴장 등 여러 가지 요인에 영향을 받으며, 기본적인 심박수와 그 조절은 일차적으로 자율신경계의 활성도 즉 교감신경계와 부교감신경계 각각의 균형에 의해 이루어진다. 현재까지 말기 신부전으로 혈액투석을 받고 있는 환자에 있어서 심박수 변이도 변화에 대한 연구는 비교적 드문 실정이다. 이에 저자들은 말기 신부전이 자율 신경계의 기능 장애와 관련이 있는지 알아보기 위해 24시간 활동 심전도를 이용하여 심박수 변이도를 조사하였다. 방법: 2006년 1월 1일부터 2007년 6월 30일까지 김원묵기념 봉생병원 신장내과에 내원한 환자 중 말기 신부전으로 진단받고 혈액투석을 시행받고 있는 30명을 대상으로 24시간 활동 심전도를 시행하고 심박수 변이도를 조사하였다. 당뇨병성 신증으로 말기 신부전에 이른 환자의 경우는 대상에서 제외하였다. 연령과 성별이 유사한 64명의 일반고혈압 환자를 대조군으로 하여 같은 검사를 시행하였다. 심박수 변이도 분석 지표는 시간 계열 분석(time domain analysis)과 주파수 계열 분석(frequency domain analysis)으로 산출 하였다. 결과: 연구대상 환자는 30명으로 남자가 17명, 여자가 13명이었고 평균 나이는 51.17±11.91이고, 범위는 30~75세였다. 또한 연령과 성별이 유사한 대조군은 64명으로 남자는 30명, 여자는 34명이었고, 평균 연령은 55.02±13.72세였으며 범위는 23~77세였다. 심박수 변이도 분석 지표 중 SDNN, HRV index, VLF, LF의 normalized unit 그리고 LF/HF가 환자군에서 대조군에 비해 통계적으로 유의하게 낮았고(p<0.05), HF의 normalized unit가 높았다(p<0.05). 결론: 말기 신부전으로 혈액투석을 받고 있는 환자들은 일반 고혈압 환자들에 비해 전반적인 자율신경계의 활성이 감소한 가운데 상대적으로 교감신경계의 활성은 감소하였고, 부교감신경계의 활성이 증가했다. Background/Aims: Heart rate variability (HRV) can be used to assess the effects of drugs and other interventions, including exercise, respiration, metabolic changes, and psychological or physical stressors, on cardiac autonomic tone. HRV is regulated by the balance of sympathetic and parasympathetic tone. Few studies pertaining to HRV in end stage renal disease (ESRD) patients have been performed in Korea. Thus, autonomic nervous system activity as indicated by HRV was investigated in patients on hemodialysis due to ESRD. Methods: We compared the pattern of cardiac sympathetic and parasympathetic activity through time- and frequency-domain analyses of HRV with 24-hour Holter monitoring in 30 ESRD patients and 64 hypertensive control subjects. The ESRD patients had undergone hemodialysis therapy at the Bongseng Hospital between January 2006 and June 2007. Results: The mean age of ESRD patients and hypertensive controls was 51.17±11.91 and 55.02±13.72 years, respectively. In the ESRD group, all time- and frequency-domain HRV measures, including the standard deviation of all normal sinus R-R intervals over 24 hours (SDNN), the HRV index, the very low-frequency (VLF) normalized unit of low-frequency (LFnorm), and the ratio of low-frequency power to high-frequency power (LF/HF), were reduced; the normalized unit of high frequency (HFnorm) was increased in the ESRD patients compared with the control group. Conclusion: The autonomic tone in ESRD patients on hemodiaysis was decreased compared with hypertensive patients. The parasympathetic tone in ESRD patients on hemodyalysis was dominant over the sympathetic tone. (Korean J Med 75:54-59, 2008)

The purpose of this study is to clarify the mediated effects of the Big Five personality factors in the relation between the fairness of judgment male gymnasts perceive and emotion. This study represents the population of gymnasts in junior high school or older, who are registered in the Korea Gymnastic Association as of 2015, and analyzes the data of 153 gymnasts participating in the national competition in May 2015. The used research tools were the questionnaire used in previous studies, which was appropriately adjusted and supplemented to suit the research purposes, and the validity and reliability were verified through the refining process which removes questions according to the exploratory factor analysis and reliability analysis. As the result of analyzing the differences according to the performance level, it showed that superior gymnasts perceived lower levels of instability and negative emotions of the negative concept, while they perceived higher level of openness, friendliness, sincerity, and positive emotions of the positive concept. As the result of examining the mediating effects of the Big Five personality factors, it was confirmed that the mediating role of the Big Five personality factors did not exist as there was no significant influence relation in the 1st phase of instability, extroversion, and openness, and there was a partial mediation in the areas of friendliness and sincerity.
