김태완,하병권,김태완 한국전산회계학회 2023 電算會計硏究 Vol.21 No.3

[Purpose]If activity-based cost calculation is a cost calculation method that can be applied to blue-chip companies with advanced ERP systems, TDABC is a relatively easy and simple cost calculation method that can be applied even to a small number of SMEs. This study attempted to confirm the usefulness of TDABC by analyzing the difference between the time-active cost calculation (TDABC) method and the existing cost calculation method based on the cost data of S, a case company in the automobile parts manufacturing industry. [Methodology]Unlike the traditional cost calculation of case company S, the process time was calculated by applying the TDABC system by the time equation. Through this, not only the actual operation level was divided into usage time and idle time, but also cost reduction and profit rate improvement measures were prepared by dividing the cost into usage cost and idle cost. [Findings]Summarizing the analysis results of this study, for case companies, the operating margin based on traditional cost calculations was 2.8%, whereas the TDABC system was analyzed as 6.7% of the operating margin for the cost of use, excluding idle costs. In other words, the cost of the TDABC system is a way to increase the operating margin along with the reduction of the idle cost sector. Therefore, it was confirmed that the introduction of the TDABC system for case companies can increase the efficiency of cost management. [implications]Unlike previous studies that calculated the cost incentive rate in the dedicated facility system, this study is significant in that it analyzed the usefulness of TDABC by applying time-driven cost calculation in the multi-species production system because case company S is building a system of general-purpose facilities. [연구목적]본 연구는 자동차 부품 제조업의 사례기업 S사의 원가자료를 바탕으로 시간동인 활동원가계산(TDABC)방식과 기존 원가계산방식과의 차이를 분석함으로써 TDABC의 유용성을 확인하고자 하였다. [연구방법]사례기업 S사의 전통적원가계산과 달리 TDABC시스템을 적용하여 프로세스시간을 시간방정식에 의해 계산하였다. 이를 통해 실질조업도를 사용시간과 유휴시간으로 구분하는 것을 물론 원가를 사용원가와 유휴원가로 나누어 원가절감과 이익률 개선 방안을 마련하였다. [연구결과]본 연구의 분석결과를 요약하면, 사례기업을 대상으로 했을 때 전통적 원가계산에 의한 영업이익률은 2.8%인데 반해서 TDABC시스템은 유휴원가를 제외하고, 사용원가 부분의 영업이익률은 6.7%로 분석되었다. 즉, TDABC시스템에 의한 원가는 유휴원가 부문의 절감과 함께 영업이익률을 높일 수 있는 방법이다. 따라서 사례기업은 TDABC시스템의 도입하는 것이 원가관리의 효율성을 높일 수 있음이 확인되었다. [연구의 시사점]본 연구는 TDABC 연구에 있어 전용설비체제에서 원가동인율을 산출한 선행연구와 달리 사례기업 S사는 범용설비의 시스템을 구축하고 있어 다품종생산체제에서 시간동인 원가계산을 적용하여 TDABC의 유용성을 분석했다는 점에서 연구의 의의가 크다.

The purpose of this study was to investigate the effect of variations in the amount of perceptual modeling in the elderly groups received prior to actively practicing a coincident-timing task. Specifically, subjects (n=60) were compared under four modeling conditions consisting of no, 1, 5 and 10 perceptual modeling trials administered by having subjects view stimulus lights on a Bassin Anticipation Runway prior to active performance. Following modeling experiences, each group performed right-to-left swing motion coincident with the illumination of the runway lights. The results were as followings. 1. During a 20 trial acquisition phase, the perceptual modeling, whether 0, 1, 5, or 10 trials, resulted in significantly no difference in absolute constant timing error(ACE) among 4 groups. 2. During a 8 trial no-KR retention phase, the 10 trial modeling group had better timing accuracy than the other modeling groups(0, 1, or 5 trials). 3. During a 20 trial acquisition phase and 8 trial no-KR retention phase, the 10 trial modeling group performed with less variable than the other modeling groups(0, 1, or 5 trials). Thus, it was concluded that the relevant information needed to enhance could be obtained with the variations of perceptual modeling in the elderly women. Therefore, perceptual modeling for the elderly women was effective for better performance, like young women.

김태완,조윤용,이연옥,이혜진 한국문화교육학회 2016 문화예술교육연구 Vol.11 No.1

본 연구는 한국사회의 다문화사회로의 이행에 있어서 미래의 주역인 대학생의 다문화수용성에 주목하였다. 구체적으로, 대학생 집단을 대상으로 다문화수용성을 측정할 수 있는 단일차원의 측정 문항을 도출하여 해당 척도가 적정 수준의 타당도와 신뢰도를 확보할 수 있는지를 검증하였다. 이를 위해, 기존 다문화수용성 척도를 수정 보완하여 대학생 207명을 대상으로 설문조사를 하였다. 조사결과, 대학생의 다문화수용성은 ‘외국이주민에 대한 거부 및 회피’, ‘외국문화와 외국이주민에 대한 개방’, ‘외국이주민에 대한 차별’, ‘외국이주민과 한국인과의 쌍방적 동화’, ‘외국이주민에 대한 고정관념’, ‘외국이주민과의 상호교류’라는 여섯 가지의 하위개념으로 구성되는 것으로 나타났다. 그리고 17개의 측정문항 중 요인계수가 높은 6개 측정문항을 중심으로 단일 차원의 대학생 다문화수용성 지수를 도출하였다. 이러한 결과를 바탕으로 이 연구결과가 가지는 학문적, 실천적 의의에 대해 논의하였다. As Korea becomes a multicultural society, it is critical for educators to improve multicultural competency among college students. Therefore, this study developed Multicultural Acceptance Scale (MAS) survey instrument for college student population, verifying the validity of this instrument. For this purpose, the study adopted a previously developed multicultural acceptance scale for Koreans and administered it for college students. A second-order confirmatory factor analysis reveals that the multicultural acceptance of college students consists of six factors, making a 6-item unidimensional scale instrument. The study further found that both participant college students’ international experience and their relationship with international friends significantly affected their multicultural acceptance, which reaffirmed that the developed scale meets the criterion-related validity. This study also discussed some theoretical and practical implications of the results.

박영춘,이상도,박준형,김지언,이 형,김태완 啓明大學校 醫科大學 1997 계명의대학술지 Vol.16 No.4

저자들은 TTE가 TTE를 실시한 환자들의 선별을 위한 예비검사가 될 수 있는지를 조사하고자 뇌경색 혹은 일과성 뇌허혈로 진단된 63명의 환자를 대상으로 TTE 및 TTE의 결과를 분석하여 다음과 같은 결론을 얻었다. TTE에서 이상 소견들의 발견은 TTE상 정상소견, 젊은 연령, 정상 동율동의 보일 경우는 빈도가 낮았으며, 임상적으로 심장질환이 의심되며 TTE상 이상이 관찰된 군에서는 훨씬 높았다. 또한 TTE는 비관혈적 방법이나, TTE를 실시할 경우에는 사망, 심실성빈맥, 저산소증등의 부작용이 생길 수 있으며, 특히 협조가 힘든 환가에서 실시가 곤란하므로 모든 환자들에게 시술하기가 어려운 점 등이 있고, 또한 TTE에서 발견된 색전원의 종류들은 입상적인 양상 및 TTE의 특이적 및 비특이적 이상소견이 있었던 경우 발견률이 높았다. 따라서 뇌경색이나 일과성 허혈환자들에서 TTE를 먼저 실시하여 이상 소견을 발견시 TTE를 실시함이 바람직하다고 생각된다. Background and Objective : We examined whether patients suffering from suspicious embolic strole may be selected for transeophageal echocardiography (TEE) on the basis of abnormal transthoracic echocardiographic (TTE) findings. Methods : We performed TTE and TEE on 63 patients after suspected embolic stroke. Patients were classified into group A if they were in sinus rhythm and had a normal TTE, and group B consisted of all other patients. Abnormal TEE findings such as left ateial spontaneous contrast, left atrial thrombus. complex aortic atheroma, and interatrial septal anomalies were correlated with clinical and abnormal TTE results. Results : Abnormal TEE findings were in 30 patients (48%) : left atrial spontaneous contrast in 12 patients (19%), left atrial thrombus in 1 patient (2%), complex aortic atheroma in 10 patients (16%) and interatrial septal anomalies in 7 patients(11%). In group A (n=17), none had left atrial spontaneous contrast, left atrial thrombus, and interatrial septal anomalies, only 2 patients(7%) had complex atheroma. In group B (n=36), 12 patients(33%) had left atrial spontaneous contrast, 8 patients (22%) had aortic atheroma, 7 patients (19%) had interatrial septal anomalies and 1 patient(3%) had left atrial thrombus. There were no significant correlations between age and abnormal TEE findings. Multivariate analysis identified an abnormal TTE to be independent predictors of TEE findings of left atrial spontaneous contrast and interatrial anomalies. Conclusion : TTE is sensitive and noninvasive screening tool in patients with suspected embolic stroke.

Seismic Performance of Low-rise Intermediate Steel Moment Frame Buildings in South Korea

김태완,유은종 한국강구조학회 2017 International Journal of Steel Structures Vol.17 No.4

The seismic performance of low-rise intermediate steel moment frame buildings following design practices of South Korea was investigated and its benefit was presented in comparison with those of customary design practice in the United States. The major features in the design and construction practices in South Korea are that the entire frames of the building are designed to resist the lateral load and beam-to-column connections are fabricated in factories. In contrast, in the United States, only exterior frames resist the lateral load and the entire beam-to-column connections are welded at the construction site. To investigate the effects of distinctive design practices on seismic performance, the example buildings were designed and evaluated with the procedure in FEMA 355F. The effect of panel zone deformation in addition to story drift was considered in performance evaluation. The evaluation results showed that the seismic performance of the buildings designed in accordance with the practice in South Korea were not significantly different from those in the United States. Therefore, design and construction practices in South Korea are a competitive way for intermediate steel moment frame buildings.

C-Quinolium(TCNQ) LB막의 열처리에 따른 UV/visible 흡광도

김태완 弘益大學校 科學技術硏究所 1993 科學技術硏究論文集 Vol.3 No.-

Thermal annealing effects of C?-quinolium(TCNQ) Langmuir-Blodgett(LB) films were studied. To see the thermal influence of the specimen, current was measured as a function of temperature in the range of 20 ∼180℃. It shows that the current increases about 4 orders of magnitude near 60 ∼ 70℃ and remains constant for a while up to ∼150℃ and then suddenly drops. Such increase of current near 60 ∼ 70℃ seems to be related to a softness of alkyl chains. Besides the electrical measurements, UV/visible(300 ∼ 800nm) absorption spectrum of the thermally annealed sample was measured to see the internal-structure change. It is found that there are four characteristic peaks. At 494nm, the optical absorption of the thermally annealed specimen at 60℃ starts to increase and stays almost constant upto∼140℃. And eventually it disappears above 180℃. After heat treatment of the specimen up to 150℃, UV/visible absorption was measured while cooling to see the reversibility.

벽면 충돌 가솔린 분무의 미립화

원영호,김태완 울산대학교 1998 공학연구논문집 Vol.29 No.2

현재 대부분의 가솔린 기관은 흡기포트에 연료를 분사시켜 혼합기를 형성하는 방법(MPI)을 채용하고 있다. 인젝터에서 분사된 연료는 포트 벽면과 흡기밸브에 충돌하여 일부는 벽면에 부착하여 액막을 형성하고 나머지는 충돌에너지에 의하여 작은 액적으로 2차 미립화된다. 이러한 충돌분무의 특성은 기관 응답성과 배기가스에 큰 영향을 미친다. 따라서 이러한 특성을 명확히 파악하는 것은 기관 성능 개선에 중요하다. 본 연구는 단공 hole노즐을 사용하여 벽면에 충돌하는 가솔린 분무의 미립화 특성을 레이저 시트광을 이용한 가시화법으로 조사하였다. 연료에 형광물질을 첨가하여 레이저로 이를 여기시켜 얻은 형광과 액적의 산란광을 동시에 촬영하여 분무의 공간적 확산, 연료농도의 분포, 미립화 정도를 정성적으로 측정하였다. 충돌각도, 충돌속도가 충돌 후 분무의 미립화 특성에 미치는 영향을 파악하였다. 벽면에 부착되어 액막이 되는 연료량도 충돌부 주위에 설치된 가는 틈새로 흘러든 연료량을 측정하여 정량적으로 계측하였다. Most gasoline engines employ a port injection system to achieve the better fuel-air mixing. A part of injected fuels adheres to the wall or intake valve and forms a film of liquid fuel. The other is secondarily atomized by the spray-wall interaction. A better understanding of this interaction will help in designing injection systems and control strategies to improve engine performance and exhaust emissions. In the present research, the spray-wall interaction was investigated by laser sheet visualization method. The fluorescence from the fuel doped with fluorescer(Rhodamine 6G) and scattering light were imaged simultaneously by a negative color film. The shape of sprays was pictured at various impinging velocities and angles. The fuel dispersion was estimated by fluorescence light, and the atomization was evaluated by the fluorescence/scattering light ratio. The amount of fuel in a film was measured by weighting the fuel trapped in a circular narrow groove around the impinging point.
