Socially Incompetent Character in The Office: Focus on Action Formations and Understanding Displays

Eunseok Ro(Eunseok Ro),Josephine Mijin Lee(Josephine Mijin Lee) 한국사회언어학회 2023 사회언어학 Vol.31 No.1

By adopting conversation analysis, this study examines how action formation and understanding displays construct a socially inept and humorous character in the TV sitcom, The Office. The analysis revealed two recurrent patterns in the main character’s interactions—improper action formation and insufficient understanding displays. Specifically, the findings showed that the main character, Michael, was construed as one that is unaware of his uncanny actions and unable to understand the interlocuter’s inferential and sarcastic remarks. The inserted interview scenes also highlighted that a conversational norm has been violated and contribute to the characterization of Michael as a quirky, socially incompetent worker. As a result, the collective sender is not only able to establish common ground with the audience but also dramatize the humorous potential of the episode. These analytic findings demonstrate that CA can be a rigorous tool for revealing the specific interactional devices that are exploited by scriptwriters to configure characters and infuse comical elements into TV sitcoms.

The sweet potato whitefly Bemisia tabasi is one of the most important pests of various horticultural crops. In addition, B. tabaci is a vector of many plant-pathogenic viruses and cause a serious secondary damage to crop plants. Association of plant-pathogenic virus with vector insects is known to be effective on the transmission capacity, fecundity, longevity of vectors including whiteflies. However, the interactive mechanisms between virus and vector insects are still poorly understood. Recently, a serious damage caused by virus disease together with B. tabasi emergence was identified at tomato glasshouse in Tongyoung. We detected the signals of Tomato Yellow Leaf Curl Virus (TYLCV) in tomato leaves and vector whiteflies using PCR amplification and confirmed its presence by those sequence comparison. To determine the effects of TYLCV acquisition on physiological status of vector whiteflies, transcript levels of genes that associated with metamorphosis, metabolism, stress and immune processes were compared between TYLCVinfected whiteflies and non-infected ones. Generally, the transcript levels of virus-infected whiteflies were lower than those of non-infected ones. In addition, the associations of endosymbiont levels within whiteflies were discussed in aspect of the acquisition and transmission of TYLCV.

It is well known that two representative methods satisfy the condition of EURO-Ⅳ regulation from EURO-Ⅲ. The first method is the reduction of NOx in an engine operation by utilizing EGR and the elimination of increased PM by DPF. However, it results in bad fuel efficiency. The second is the strategy to reduce PM and emit the high NOx concentration. In other words, the concentration of PM produced by high efficiency combustion sufficiently meets the requirement of regulation, and NOx generated in this process can be removed by SCR system. While it has a good fuel efficiency relative to the first method mentioned above, its social infrastructure is demanded. In this paper, the number distribution of nano PM has been evaluated analyzed by Electrical Low Pressure Impactor(ELPI) in two different case of engine condition, EURO-Ⅲ base engine with DPF system and EURO-Ⅳ level engine(modified from EURO-Ⅲ) with SCR system. From the result of this study, the number distribution of nano PM in a modified EURO-Ⅳ engine was similar level compared to the result of EURO-Ⅲ engine installed DPF system. In case of EURO-Ⅳ engine with SCR system, the particle number was increased slightly in proportion to the amount of urea injection on big size particles, whether AOC is used or not.

Effects of FeCl₃ addition on the operation of a staged anaerobic fluidized membrane bioreactor (SAF-MBR)

Lee, Eunseok,McCarty, Perry L.,Kim, Jeonghwan,Bae, Jaeho IWA Publishing 2016 Water Science & Technology Vol.74 No.1

<P>The effects on sulfur removal and membrane fouling resulting from FeCl3 addition to an anaerobic fluidized membrane bioreactor (AFMBR) in a staged AFMBR (SAF-MBR) was investigated. Total sulfur removal in the SAF-MBR was 42-59% without FeCl3 addition, but increased to 87-95% with FeCl3 addition. Sulfide removal in the AFMBR increased to 90% with addition of FeCl3 at a molar Fe3+/S ratio of 0.54 and to 95% when the ratio was increased to 0.95. Effluent sulfide concentration then decreased to 0.3-0.6 mg/L. Phosphate removals were only 19 and 37% with the above added FeCl3 ratios, indicating that iron removed sulfide more readily than phosphate. Neither chemical oxygen demand nor biochemical oxygen demand removal efficiencies were affected by the addition of FeCl3. When the AFMBR permeate became exposed to air, light brown particles were formed from effluent Fe2+| oxidation to Fe3+. FeCl3 addition, while beneficial for sulfide removal, did increase the membrane fouling rate due to the deposition of inorganic precipitates in the membrane pores.</P>

Lee, Dae Hoon,Lee, Jae-Ok,Kim, Kwan-Tae,Song, Young-Hoon,Kim, Eunseok,Han, Hyun-Sik Elsevier 2011 International journal of hydrogen energy Vol.36 No.18

<P><B>Abstract</B></P><P>A plasma-assisted hydrocarbon selective catalytic reduction (HC-SCR) system was constructed and its de-NOx performance was evaluated. An onboard plasma reformer supplied the reducing agent in the system. The reformate gas composition can be varied or the H<SUB>2</SUB>/HC ratio can be controlled by controlling the operating conditions. This ratio is important in the SCR process since the performance of the SCR catalyst is dependent on the composition of the reducing agents. Two catalysts were prepared for the test: those having lower-temperature and higher-temperature windows of operation. The proposed system showed a much enhanced de-NOx performance. Onboard plasma reforming enabled achievement of an enhanced de-NOx performance using about half the typical catalyst volume. Fuel penalty of the system remained at ∼3%, with a possibility of further reduction without severe performance degradation. The system volume and power consumption also satisfy conditions necessary for its commercial application. Therefore, it appears suitable for commercial application.</P> <P><B>Highlights</B></P><P>► Evaluation on the engine bench test of plasma assisted HC SCR system was carried. ► Plasma reformer produced controlled composition of hydrogen and hydrocarbon species. ► Even in high S/V of 85,000/hr, plasma reformer resulted in much enhanced de-NOx rate. ► De-NOx rate, start-up time and aging test was done for the on board plasma reformer. ► All the results showed that the plasma HC SCR system is prominent de-NOx solutions.</P>

Prediction of Rotation Rate of a Free-Rolling Tail Using CFD

Eunseok Lee,Kyoung Tai Kang,Kwang Seop Lee 한국전산유체공학회 2014 한국전산유체공학회 학술대회논문집 Vol.2014 No.10

Numerical simulations are performed to predict the rotation rate of the free-rolling tail of a canard-tail missile configuration. A set of four tail fins placed around a cylindrical missile body is modeled to free-roll with respect to the axial axis of the body. Aerodynamic forces and moments acting on the fin set are computed in a time-accurate manner and the resulting rolling motion of the fin set is updated in real time using the Dynamic Fluid Body Interaction (DFBI) technique. The test condition spans the Mach number of 1.05, 1.2, 1.6, body roll angle of 22.5 degrees and angle of attack up to 15 degrees, and canard roll deflection angle of 5 degrees. It is observed that the rotation rate decrease with increasing angle of attack, which agrees well with the wind tunnel test results. The dynamics of the rotational motion and the aerodynamic roll moment are analyzed to find the physics governing the rotation rate.

과학로켓 3호(KSR-3) 자력계 데이터 분석을 통한 로켓비행자세 연구

이은석,장민환,이동훈,김성수,황승현,이선민 경희대학교 자연과학종합연구원 2003 자연과학논문집 Vol.9 No.1

2002년 11월에 발사된 KSR-3 과학 로켓에 탑재된 자력계의 데이터 처리 결과에 대해 논한다. KSR-3 과학 로켓에는 로켓의 비행 자세 정보 획득을 위한 Fluxgate 자력계인 AIM (Attitude Information Magnetometer)과 지구 자기장 섭동 측정용 Search-coil 자력계인 SIM (Scientific Investigation Magnetometer)인 2종류의 자력계가 탑재되었었다. KSR-3 과학 로켓의 발사부터 비행종료까지 총 비행시간 2314초 동안 AIM과 SIM에서 각 축별 데이터를 성공적으로 획득하였다. 먼저 AIM은 획득된 데이터를 수치계산법 및 자체 개발한 MFD_View 변환 프로그램, Spline 보정법을 이용하여 데이터를 분석하였고, 자체 개발한 비행정보 획득 프로그램을 이용하여 시간에 따른 로켓의 비행상태를 확인 중에 있다. 차후 로켓의 좌표값을 이용해 지구 자기장의 여러 성분값 및 데이터 처리 결과들을 비교 분석하여 자력계가 차후 발사되는 로켓의 자세제어에 적합한지 알아볼 예정이다. SIM은 지구 자기장 섭동 현상 관측 및 로켓의 이벤트에 대한 정보를 확인하였다. SIM 데이터는 로켓의 최고 고도가 427㎞밖에 안되어 지구 자기장 섭동 현상을 관측하지 못했으나 로켓의 시간대별 이벤트 현상을 확인할 수 있었다. We describe the result of the two onboard magnetometers of KARI(Korea Aerospace Research Institute)'s sounding rocket. KSR-3, which was launched in November 2002. The KSR-3 magnetometers consist of the fluxgate magnetometer, AIM(Attitude Information Magnetometer) for acquiring the rocket flight attitude information and the search-coil magnetometer, SIM(Scientific Investigation Magnetometer) for the observation of the Earth's magnetic field fluctuations. We acquired 3-axis data of the KSR-3 magnetometer AIM and SIM for 231.4 seconds flight time of science rocket AIM data was analyzed using numerical method, the MFD_View conversion program that we develop independently and Spline method. And we studied the rocket flight attitude information using flight information acquisition program that we developed. The resulting dc magnetic vector field was compared with the IGRF(International Geomagnetic Reference Field). Although SIM could not observe the Earths magnetic field fluctuation, it confirmed the various events of rocket.
