비대칭 코어를 위한 복잡도 시그널링 기반 HEVC 병렬처리

노현준 가천대학교 일반대학원 2018 국내석사

본 연구는 현재 널리 보급이 시작되는 4K UHD 영상들과 전력 소모를 줄이는 장점으로 인해 모바일 디바이스에 많이 사용되는 비대칭 멀티코어를 위한 연구이며, 비대칭 멀티코어에서의 디코딩 속도 향상을 위한 새로운 디코딩 기법을 제안하였다. 비대칭 멀티코어에서 타일을 이용한 병렬처리 디코딩을 수행할 때, 제안하는 기법을 통해 각 코어의 성능비와 할당되는 작업량을 비례하게 하여 디코딩 작업의 시간을 줄이는 것이다. 작업량을 비례하게 하기 위해서 각 타일의 복잡도를 판단해야 하는데, 이때 본 연구는 PU의 분할 정도를 이용하여 복잡도를 판단하였다. 이 방식은 다른 복잡도 판단 방법들보다 간단하고 클라이언트의 부담이 적다는 장점이 존재한다. 디코더 측에서는 인코더에서 전송받은 데이터들을 이용하여 회귀분석 작업과 각 코어별 타일 할당 등을 수행하여 전체적인 디코딩 속도 향상이 가능하게 된다. 제안하는 기법을 사용한 테스트를 위해 HEVC표준화가 적용된 인/디코더를 사용하고 모바일 환경에서 테스트를 실시하였다. 또한 실험을 위해 4K UHD 영상과 Full HD 영상을 사용하였으며, 각 영상을 타일로 분할하고 Random Access방식으로 인코딩하여 사용하였다. 실험 결과 약 9~16%의 디코딩 속도 향상을 보였다.

대학생의 부적응적 완벽주의와 우울 간의 관계 : 반추와 경험회피의 연속매개효과

노현준 아주대학교 2015 국내석사

본 연구는 완벽주의와 우울 간의 관계를 반추와 경험회피가 연속매개 하는지를 검증하였다. 이를 검증하기 위해 276명의 피험자들에게 부적응적 완벽주의, 반추, 경험회피 및 우울을 평가하는 설문지를 실시하였다. 연구결과, 반추의 하위요인인 몰두와 경험회피가 부적응적 완벽주의와 우울 간의 관계를 연속매개한다는 것이 밝혀졌다. 부적응적 경험회피와 우울 간의 관계에서 몰두와 경험회피의 순차적인 관계를 확인한 이 결과는 기존 연구들의 결과를 확장시켰다는 점에서 의미가 있다. 논의에서는 본 연구의 제한점 및 후속 연구의 방향을 제시하였다.

노현준 부산외국어대학교 일반대학원 2020 국내석사

The purpose of this study is to provide basic scientific data to effectively apply the performance of the rowing competitors through the application of the kinesio-tapping therapy and circuit-tapping therapy Consequently, no statistically significant difference was found in the 2000 m record through the rowing ergometer, but any improvements in the Watt, Pitch and Final record within the margin of error are considered to affect the performance of the row-tapping therapy. Based on this, it is believed that continuous research is required through the application of systematic line-tapping therapy and changes in research targets to various competition events requiring aerobic endurance and muscle strength, such as coordination competitions, which will result in more objective evidence.

A Study on the Polyurethane Curing-delayed Action Catalyst based on N-Heterocyclic Carbene (NHC)-FeCl3

노현준 전남대학교 2019 국내석사

In this research, TPB(triphenylene bismuth) is commercially used as solid propellant and 2K-system polyurethane polymerization delaying catalyst, N-hetero cyclic carbene(NHC)-FeCl3 is investigated to examine polyurethane polymerization delaying performance. Common polyurethane catalyst cannot delay or control the rate of polyurethane polymerization reaction and contains heavy metal, which endangers health of engineers. To improve these shortfalls, NHC-FeCl3 is coordinately linked to N-hetero cyclic carbene to produce a catalyst. In this research, the structure of this catalyst is examined and its activation energy using DSC is analysed to assess polyurethane polymerization delaying performance. When this catalyst is added to polyurethane polymerization reaction, there is no activation at room temperature but curing of polyurethane rapidly occurred after increasing the temperature from over 60℃. Thus, it is found that polymerization delaying successfully occurred in this catalyst. Similar to how energy from coordinate bond between commercial TPB catalyst and bismuth(Bi) makes polyurethane polymerization reaction, low binding energy of FeCl3 coordinately linked to NHC-FeCl3 catatlyst’s carbene site makes activation of polyurethane polymerization low while DSC heat analysis found that after polyurethane polymerization effectively occurred after the temperature increased over 60℃.

Development of Plasma Information Based Virtual Metrology (PI-VM) for Drifting Deposition Process

노현준 서울대학교 대학원 2018 국내박사

In semiconductor-fabrication industry, virtual metrology (VM) is one of promising technology to achieve advanced process control (APC) for plasma-assisted process because it can provide metrology data for every wafer. VM is defined as the technology of prediction of metrology variables using process state (equipment and sensor) and wafer state variables. However, prediction reliability of VM is very sensitive to the quality of data and the selection of data mining technique, causing the limitation of its APC applications. Also, the required prediction reliability of VM is getting higher as the critical dimension of semiconductor devices sharply shrinks. In line with this trend, development of phenomenological-based VM which includes information about the plasma-assisted process reactor is important in the sophisticated control of semiconductor and display device manufacturing. Note that reactor is defined as process vessels that are used in semiconductor manufacturing industries for carrying out chemical reactions with assistance of plasma. The wafer state variables of plasma-assisted process, especially plasma-enhanced chemical vapor deposition (PECVD), are governed by the influx of reactive species on wafer, such as radicals, metastables, and ions. These influxes are mainly produced by electron-impact collision reactions with collision partners and destructed by reactions at reactor-wall. Thus, the wafer state variables are complex function of electron-energy distribution function (EEDF) which governs reaction rate constant (m3s-1) in plasma-volume, and reactor-wall condition which governs reaction rate at reactor-wall, such as recombination probability. The plasma-assisted process often drifts with the operation time caused from the phenomena related to the gradual deposition of byproducts or fragments of feedstock gas on reactor-wall. This drift of reactor-wall condition changes the flux of reactive species through the desorption of residues or deactivation of reactive species at reactor-wall. It also changes the gas composition in plasma and EEDF through additional elastic and inelastic collision processes. The changed EEDF induces the variation of influx of reactive species. Therefore, the reliable VM should include the variables that represent EEDF and reactor-wall condition. This concern is important specifically for the long-term application of VM. In this dissertation, two plasma-information (PI) variables are defined as the state variables of plasma-assisted processes affecting the flux of reactive species: Monitoring variable for reactor-wall condition (named PIWall) which represents the film buildup on reactor-wall, and another variable for plasma-volume (named PIVolume) which corresponds to electron density and electron temperature (or EEDF). These PI variables are determined by using plasma spectroscopy which analyzes the optical emission spectra based on the excitation equilibria in plasma. PIWall is determined by analyzing the light transmittance at the contaminated window based on line-intensity ratios from the same upper energy level. In the development of PIWall, it is assumed that the film deposition on quartz window is roughly following that of reactor-wall surface. PIVolume is determined by analyzing line-intensity ratios from different upper energy levels based on collisional-radiative model (CRM). The evaluation of influence of each variable on PI-VM for single-layer nitride PECVD shows that the electron density affects the formation of N containing species through governing the collision reaction with low threshold energy. It also shows that the electron temperature affects the formation of Si containing species through electron-impact collisions with high threshold energy. Meanwhile, PIWall affects the formation of N containing species, especially near the reactor-wall. PI-VM is applied to predict layer-to-layer nitride film thickness in nitride/oxide multi-layer PECVD used for 3D NAND fabrication in the mass production line. The evaluation of influence of each variable on PI-VM demonstrates that PIWall is the highest contributing variable in whole layers and PIVolume contributes in the latter region of layers. In the trend of increasing the number of nitride/oxide layers to increase device density, PI-VM offers provide the key phenomena of plasma to be managed. Therefore, PI-VM is expected to provide the fundamentals to develop advanced process control (APC) and fault detection and classification (FDC) for plasma-assisted processes. Also, it provides the way to apply the plasma spectroscopy in the basic plasma diagnostics technology to plasma-assisted process.
