Air textured yarn(ATY) samples were prepared from hollow PET 75/24(SDY) and PET 100/192(SDY) under the different air pressures(6 bar~12 bar) and interlaced yarn(ITY) samples were prepared from hollow PET 75/24(POY) and PET HS 40/24 under the different air pressures(3 bar~6 bar) and two speeds(400 and 450 m/min) to determine their hollowness and physical properties. Measured physical properties included unit weight, tenacity, elongation, and dry and wet shrinkage. The important results of this study were: 1) The hollowness of ATY samples decreased with increasing air pressure. The hollowness decreased to 27% when the air pressure increased from 6 bar to 12 bar and the rate of decrease was most noticeable above 9 bar. In addition, the unit weight of samples increased with the air pressure and the rate of increase was most noticeable above 8 bar. However, there was little effect of air pressure on the physical properties. 2) The hollowness of ITY samples decreased with increasing the air pressure. The hollowness decreased to about 34% when the air pressure increased from 3 bar to 6 bar and the rate of increase was most noticeable above 4 bar. The number of entanglement of the samples increased with the air pressure. However, there was little effect of the air pressure on the physical properties.

최근에 사용되고 있는 남성용 정장 중, 여름용 30종, 겨울용 30종 등 총 60종을 시료로 하여 이들의 온열특성 중 보온성(무풍시=0.2 m/sec 이하, 풍속시=1.2 m/sec)과 이와 관련된 물성, 즉 공기투과도, 무게, 두께 등을 측정 및 분석하여 앙상블 및 가먼트의 보온성을 예측하는 회귀식을 개발하였다. 그 결과로는 일반적인 남성용 정장의 물성으로 두께 및 무게는 겨울용이 높았으며, 여름용과 겨울용을 확실히 구별할 수 있는 인지는 공기투과도였는데 여름용의 공기투과도는 겨울용보다 약 3~6배 정도 높았다. 남성용정장의 온열특성을 보면 겨울용 정장의 보온성이 여름용보다 높았고, 풍속이 있을 때 앙상블의 보온성은 최대 30% 정도 감소하는 경향을 나타내었다. 또한, 정장상하의 물성을 독립변수로 하여 가먼트 및 앙상블의 보온성을 추정하는 회귀식을 개발하였는데, 회귀식분석결과, 정장앙상블의 보온성에 영향을 주는 인자는 두께, 무게, 및 사이즈로 나타났다. The thermal resistance of 60 men's suits for summer and winter was measured to determine their thermal characteristics and physical properties, including air permeability, weight, and thickness of the jackets and trousers consisted of the ensembles were measured to predict the thermal resistance of garments and ensembles. In this study, general physical properties of the men' suit ensembles were determined. In general, thickness and weight of winter ensembles were greater than those of summer ensembles. A factor which could distinguish the difference between summer and winter ensembles was the air permeability. The air permeability of summer ensembles was 3~6 times greater than those of winter ensembles. For the thermal characteristics, the thermal resistance of winter ensembles were higher than those of summer ensembles. When the wind was involved, the thermal resistance of both ensembles decreased up to 30%. In addition, the equations were developed to predict the thermal resistance of the garments and ensembles when there was no air velocity and the thermal resistance of the ensembles with air velocity of 1.2 m/sec. Looking at the equations, thickness, weight, and size of the garments were the definite factors that affect the thermal resistance of the samples.

The purpose of this study was to examine the effect of heat-setting temperature and time and winding tension on the physical properties of polyester filament yarn during heat setting. The sample used was polyester 75 D/36F SD. The sample was treated with temperature of 80-12$0^{\circ}C$ and time of 20-120 min by the use of vacuum dryer with the tension of 5-35 g. The tensile characteristics including tenacity, elongation, and initial modulus and boil-off shrinkage of treated samples were examined. In addition, thermal stress analysis including thermal stress, initial temperature of shrinkage, and peak and rupture temperature of treated samples was evaluated. The results were as follows. 1) As heat-setting temperature and time increased, there were little change in tenacity and elongation of treated samples, but initial modulus, boil-off shrinkage, and thermal stress decreased and initial temperature of shrinkage and peak temperature increased. 2) As winding tension increased tenacity, elongation, initial modulus, boil-off shrinkage, and thermal stress increased, but initial temperature of shrinkage and peak temperature decreased.

본 논문에서는 두 가지의 새로운 형태의 non-inverting BiCMOS 구동회로를 제안한다. 이들은 pull-dwon용 바이폴라 트랜지스터의 베이스를 pMOS 트랜지스터를 통해 충전시킴을 그 특징으로 한다. 이들의 pull-up시의 지연시간은 기존의 BiCMOS 구동회로들보다 20%~47% 작다. 또한 본 논문에서 제안하는 구동회로에 사용되는 MOS 트랜지스터의 갯수는 기존의 구동회로에서보다 1~3개가 적기 때문에 그 차지하는 면적이 감소된다. In this paper two new non-inverting type BiCMOS drivers are proposed. These are characterized by the use of pMOSFET's in charging the bases of pull-down bipolar transistors. The delay time in pull-up transition of the proposed drivers is 20%-47% shorter than that of the drivers of current using. The proposed drivers use 1-3 fewer MOSFET's in comparison with the drivers of current using.

이 연구는 태권도 시범단원의 일탈적 과잉동조 기제를 파악하고 어떠한 현상이 나타나는지 구명하고자 하였다. 이러한 목적을 달성하기 위하여 국가대표급 시범단 경험이 있으며, 대학 태권도 시범단 경험을 한 9명을 연구참여자로 선정하였다. 문헌자료, 심층면담 등을 이용하여 자료를 수집하였고, 수집된 자료는 텍스트 분석을 통해 분석한 후 Coakley의 일탈적 과잉동조, 스포츠 윤리규범 개념을 적용하여 해석하였다. 자료의 수집과 분석과정에서 연구의 윤리성과 진실성에 대한 검증을 지속적으로 받았다. 이러한 결론을 통해 도출된 결론은 다음과 같다. 첫째, 태권도 시범단원의 일탈적 과잉동조 기제는 개인적 발생기제와 문화적 발생기제가 나타났다. 개인적 발생기제는 국가대표라는 타이틀, 시범을 하면서 느끼는 희열이다. 문화적 발생기제는 태권도 시범단 문화, 학교 중심의 구조화된 정체성이다. 둘째, 태권도 시범단원의 일탈적 과잉동조 현상은 우선순위에 밀린 개인일정, 해외파견을 가기 위한 지나친 경쟁, 신체(부상) 방임, 무리한 기술 요구에 대한 순응이 나타났다. 앞선 결과에서 나타난 개인적 발생기제와 문화적 발생기제가 상호작용하여 일탈적 과잉동조 현상이 나타났다. The purpose of this study was to examine the mechanism and phenomenon of deviant overconformity among Taekwondo demonstration team members. In order to achieve this purpose, nine people who have worked as a university Taekwondo demonstration team and have worked as a national representative demonstration team (Korea Taekwondo Association, Kukkiwon, World Taekwondo Federation) were selected. Data were collected using literature data and in-depth interviews, and the obtained data were interpreted using Coakleys concept of deviant overconformity tuning. In the process of collecting and analyzing data, the authenticity of data and the ethics of research were continuously verified. The results of the process are as follows. First, the deviant overconformity mechanism of the Taekwondo demonstration team was found to be a personal and cultural mechanism. The personal mechanism was the joy felt at the national team title and demonstration. The cultural generation mechanism was found to be a structured identity centered on the culture and school of the Taekwondo demonstration team. Second, the deviant overconformity phenomena caused by individual schedule pushed back order of priority, excessive competition for overseas country dispatch, body(injury) neglect, and adaptation about impractical skill demand . As a result, deviant overconformity was caused by interacting personal and cultural generation mechanisms.

The stock market stabilization fund is a fund that purchases stocks under the leadership of the government for the purpose of stabilizing stock markets. Compared to the bond market and foreign exchange market stabilization policy, there are pros and cons about the stock market stabilization fund as it raises issues such as the possibility of discretionary wealth redistribution and the inherent risks in the liquidation process. By analyzing domestic and overseas instances, this paper investigates the market stabilization effect of the fund, examine the related controversies, and document matters to be considered before and after introducing the policy. For overseas cases, this paper summarizes and compares the backgrounds and policy effects of stock market stabilization funds or programs in Taiwan(1996), Hong Kong(1998), Japan(2010), and China(2015). Although common characteristics that are sufficient conditions for government’s stock market intervention are not found, previous studies show that the programs helped to reverse the declining trend in stock prices and stabilize the market. In South Korea, since the first introduction in 1990, stock market stabilization fund has been made in year 2003, 2008, 2020, and 2022. The 1990 fund was implemented for the purpose of overcoming the stock market recession after mid-1980. The 2003 fund was launched to 64respond to the sharp decline of the KOSPI index in 2002 owing to the credit card companies’ crisis and the possibility of the Iraq War. The 2008 fund was created when the domestic stock market collapsed due to the global financial crisis. The 2020 and 2022 funds are related to the COVID-19 incident and the rapid increase in global interest rates, separately; they were not actually implemented. This paper empirically analyzes whether the introduction of the past five funds in Korea made intended effects on stock price returns, volatility, and liquidity. The effects of the fund policy appears to exist in some cases; but the policy effects may be due to other policies implemented around those times. I.e., because identification of the effect of the funds is not complete, the effect must be judged conservatively. Because the funds have unintended consequences of redistributing wealth, the risk of the liquidation process, uncertainty about improving corporate financial efficiency, and the possibility of estimation bias in the policies, government must be careful in implementing the policy. This paper presents matters to be reviewed prior to policy implementation and matters to be considered after implementation.
