In-Woo Jun(In-Woo Jun),Kyoung-In Kim(Kyoung-In Kim) 한국무역연구원 2022 무역연구 Vol.18 No.6

Purpose – Among the many factors affecting corruption, cultural factors cannot be overlooked. This study examines if there is any relationship between culture and corruption. For this purpose, Hofstede’s cultural dimension index and the Corruption Perception Index (CPI) for 116 countries were used. Design/Methodology/Approach – This study used secondary data published by two institutions: Hofstede Insights and Transparency International. First, the latest Power Distance Index (PDI) and Individualism Index (IDV) of 116 countries were obtained from Hofstede Insights. Second, the latest 2021 CPI of 116 countries was gained from Transparency International. Two hypotheses were developed. To examine the relationship between the variables, a correlation analysis was adopted. Findings – According to the analysis results, hypothesis 1 received statistical support indicating more corruption tends to occur in countries with high power distance culture. Hypothesis 2 is also accepted that more corruption occurs in countries with a strong collectivism culture. Research Implications – The result of this study implies that centralization of power into the higher echelons may hinder effective communication within organization, and often leads to strategic decision-making errors and even corruption. In addition, excessive in-group collectivism is an obstacle to monitoring and blocking internally generated corruption and sometimes demands individual sacrifice.

Engineering of AlON interlayer in Al₂O₃/AlON/In_0.53Ga_0.47As gate stacks by thermal atomic layer deposition

Lee, Woo Chul,Cho, Cheol Jin,Park, Suk-In,Jun, Dong-Hwan,Song, Jin Dong,Hwang, Cheol Seong,Kim, Seong Keun ELSEVIER 2018 CURRENT APPLIED PHYSICS Vol.18 No.8

<P>The presence of an AlN interfacial layer in high-k/In0.53Ga0.47As gate stacks improves the interfacial properties and enhances the electrical performance of devices. However, pure AlN is rarely grown by atomic layer deposition (ALD) because of the low reactivity of NH3 toward the common Al-precursor and the predisposition to oxidation of the grown AlN layer. Although a plasma-enhanced ALD technique significantly suppresses the oxygen content in the grown AlN layer, the deterioration of the interface properties by plasma-damage is a critical issue. In this work, an AlON interlayer was engineered by optimizing the NH3 feeding time in thermal ALD to improve the interface quality in Al2O3/AlON/In0.53Ga0.47As capacitors. It was determined that a mere increase in the NH3 feeding time during the ALD of the AlON film resulted in a higher nitrogen incorporation into the AlON interlayer, leading to a reduction in the interface trap density. Furthermore, the out-diffusion of elements from the In0.53Ga0.47As layer was effectively suppressed by increasing the NH3 feeding time. This work demonstrates that simple process optimization can improve the interface quality in high-k/In0.53Ga0.47As gate stacks without the use of any plasma-activated nitrogen source.</P>

Woo, Sung Yun,Yoon, Young Jun,Cho, Seongjae,Lee, Jung-Hee,Kang, In Man American Scientific Publishers 2013 Journal of Nanoscience and Nanotechnology Vol.13 No.12

<P>Tunneling field-effect transistors (TFETs) based on the quantum mechanical band-to-band tunneling (BTBT) have advantages such as low off-current and subthreshold swing (S) below 60 mV/dec at room temperature. For these reasons, TFETs are considered as promising devices for low standby power (LSTP) applications. On the other hand, silicon (Si)-based TFETs have a drawback in low on-state current (lon) drivability. In this work, we suggest a gate-all-around (GAA) TFET based on compound semiconductors to improve device performances. The proposed device materials consist of InAs (source), InGaAs (channel), and InP (drain). According to the composition (x) of Ga in In1-xGa(x)As layer of the channel region, simulated devices have been investigated in terms of both direct-current (DC) and RF parameters including tunneling rate, transconductance (g(m)), gate capacitance (Cg), intrinsic delay time (tau), cut-off frequency (fT) and maximum oscillation frequency (f(max)). In this study, the obtained maximum values of tau, fT, and f(max) for GAA InAs/In0.9Ga0.1As/InP heterojunction TFET were 21.2 fs, 7 THz, and 18 THz, respectively.</P>

자연 방사선 피폭선량 중 우주선 전리 성분의 기여를 정량하기 위하여 LiF TLD를 이용하여 약 1년반에 걸쳐 3개월 간격의 주기적 측정을 수행하였다. TLD는 세가지를 사용하였는데 그것은 칩과 PTFE원판형으로 된 두 가지의 ?LiF와 중성자 성분의 기여를 가려내기 위한 원판형의 ?LiF였다. 선량측정은 뱃지에 넣은 TLD를 충남대학교 대덕 캠퍼스의 한4층콘크리트 건물내 3층의 한 연구실에 설치한 10-15㎝ 두꼐의 납차폐 상자에 넣어서 90일 간격으로 다섯 주기 동안 수행하였다. 비교 연구를 위하여 3"Φ×3" 원통형NaI(T1) 섬광 검출기와 1024채널 MCA를 이용하여 3MeV 이상의 우주선 경성분에 대한 분광분석을 병행하였는데 그 결과 옥내 차폐체를 이용한 TLD측정치는 옥외 우주선 전리 성분의 약 75%를 측정하고 있음이 밝혀졌다. 이와 같은 차폐 손실을 보정한 TLD측정 결과에 의하면 충남대 대덕 캠퍼스 옥외에서 우주선 전리 성분의 기여는 34.3±1.1nGy-h¹로 나타났는데 이것은 이 측정 지점에서 예측할 수 있었던 선량 값과 매우 잘 일치하는 것이다. In order to quantify the contribution of cosmic-ray ionizing component to the dose given by natural background radiation, a series of measurement has been carried out using LiF TLDs for about one and a half years on quaterly basis. Three different types of LiF TLDs namely, chips and PTFE based disks of ?LiF, and the same disks of ?LiF for identifying possible contribution of neutron component were used. Measurements were made by placing badge-incased TLDs in a lead castle of 10 to 15㎝ thick installed in a room n the third floor of a four-story building in CNU Daedeok campus for 5 cycles of 90 days. For comparison a series of spectrometric study was also performed for the energy region over 3 MeV using a 3"Φ×3"NaI(T1) scintillation detector in association with an MCA of 1024 channels, and it was found that the data obtained by the TLDs placed in the lead castle indicate 75% of the dose given by outdoor cosmicray component. The results obtained by the TLDs through correction for shielding loss show that the outdoor dose contribution of ionizing component of cosmic rays at this campus is 34.3±1.1nGy/h which satisfactorily agrees with that expected for our particular location of measurement.

승객의 안전을 도모하기 위해서는 충돌시 발생하는 구조부재의 에너지홉수특성을 적절히 제어하여 자동차의 구조를 설계해야한다. 현재 차량구조부재의 에너지흡수 능력을 향상시키 기 위해서 여러 가지 형상과 재질에 따른 연구가 활발히 진행되고 있다. 본 연구에서는 자동차 충돌시 에너지 흡수를 적절히 제어하여 승객의 안전을 도모할 수 있는 최적의 구조부재를 개발하고자 한다. 특히 자동차의 전면충돌시 에너지 흡수량이 가장 큰 부재인 사이드 부재의 기본형상인 사각단면부재에 대하여 제어기의 유무 제어기의 두께와 높이에 따른 에너지흡수능력과 평균압궤응력 및 변형모드를 고찰하였다. 에너지 흡수 제어기를 이용하여 에너지흡수량 및 평균압궤하중이 제어기를 사용하지 않은 경우보다 15∼20%정도 증가하였으며, 제어기의 높이와 두께 또한 에너지 흡수에 영향을 미쳤다. The structural members must be designed to control characteristics of energy absorption for protecting passengers in a car accident. Study on collapse characteristics of structural member is currently conducted in parallel with other studies on effective energy absorption capacity of structural members with diverse cross-sectional shapes and various materials. This study concerns the crashworthiness of the widely used vehicle structural members, square thin-walled tubes, which are excellent on the point of the energy absorption capacity. The absorbed energy, mean collapse load and deformation mode were analyzed for side member which absorbs most of the collision energy. To predict and control the energy absorption, controller is designed in consideration to its influence such as height. thickness and width ration in this study. The absorbed energy and mean collapse load of square tubes was increased by 15∼20% in using the controller and energy absorbing capability of the specimen was slightly changed by change of the high controller's height.

It has recently been reported that gamma-inteferon(INF-r) and tumor necrosis factor(TNF) or lipopplysaccharide(LPS) activate macrophages to kill intracellular parasites by means of nitrc oxide (NO). It is now generally accepted that NO is the endothelium-derived relaxing factor, and that it also paticipates in the regulation of the nervous and immune systems. Activated macrophages form NO?? and NO?? from the terminal guanidino nitrogen atoms of L-arginine by the process now known to proceed via the formation of NO. This pathway is inhibited by the L-arginine analog(N?? monomethyl-L-arginine; N??MMA), forms L-citrulline as a co-product and is responsible for the cytotoxic action of macrophages. In this study, the authors found that INF-r and/or LPS induced murine macrophages to kill Rickettsiae tsutsugamushi in vitro and macrophages from BCG-infected mice got the host resistance against R.tsutsugamushi in vitro as well as in vivo. The rickettsicidal effect induced by the combination of INF-r and/or LPS induced mice got the host resistance against R.tsutsugamushi in vitro as well as in vivo. The rickettsicidal effect induced by the combination of INF-r and/or LPS can also be completely inhibited by N??MMA, leading to a dose-dependent inhibition of NO production. These datademonstrate that INF-r and/or LPS as well as BCG-activated macrophages mediate host resistance aganist R.tsutsugamushi infection through NO, which is necessary for the intracellular parasite.

We need the constitute of Emergency medical system that connect prehospital care of inhospital care effectively for optimal treatment of emergency patient. The analysis of actual condition of our emergency medical system, through study of mortality case in emergency medical center will be a aid to the constitute. The authors performed a review on the records of 60 cases who died in Ajou university Emergency medical center during management, since June 1994 to september 1995. Among the 60 patient, 72% were male and 28% were female. In nontrauma patient, 6th decade was many, in trauma patients, 3rd and 5th decade was many. Among the 60 patient, 33% were traumatic cases, 66% were nontraumatic cases. Among the traumatic patients, more than half of the cases were due to motor vehicle accidents. The most frequent time interval from onset of emergent situation to arreving at emergency center was more than 2 hours. The most common transfer method was by 119 ambulance. In most cases, prehospital treatments were not taken. In most cases, initial mental status was comatose, and systolic blood pressure was less than 60 mmHg. Most cardiovascular resuscitation was done in 30 min. to an hour. In cases as traffic accident of ischemic heart disease, where rapid transportation of the patient is critical for the patient's survival, however, in most cases it took more than two hours to bring such patients to hospital, and first aid treatment before arrival to hospital was rare. No prehospital treatment was done to nearly all patient. In many cases the patient was already in under coma or shock state. The inhospital care at emergency center was made relatively quickly and adequately. The mean duration of cardiopulmonary resustation was 30min to one hour. From this study, we could notice the poor quality of prehospital care in the region ,near Ajou university hospital, and we came to know that the improvement of quality of prehospital care was the most important factor to reduce the motality of emergency department patient. that is, in the treatment of emergency patients, weak points has been revealed in the pre-hospital treatment, the improvement of which is important factor for the survival of emergency patients.
