        글리치를 고려한 매핑가능 클러스터 생성 방법을 이용한 저전력 알고리즘

        김재진,Kim, Jaejin 디지털산업정보학회 2016 디지털산업정보학회논문지 Vol.12 No.2

        In this paper presents a low power algorithm using a feasible cluster generation method considered glitch. The proposed algorithm is a method for reducing power consumption of a given circuit. The algorithm consists of a feasible cluster generation process and glitches removal process. So that glitches are not generated for the node to which the switching operation occurs most frequently in order to reduce the power consumption is a method for generating a feasible cluster. A feasible cluster generation process consisted of a node value set, dividing the node, the node aligned with the feasible cluster generation. A feasible cluster generation procedure is produced from the highest number of nodes in the output. When exceeding the number of OR-terms of the inputs of the selected node CLB prevents the signal path is varied by the evenly divided. If there are nodes with the same number of outputs selected by the first highest number of nodes in the input produces a feasible cluster. Glitch removal process removes glitches through the path balancing in the same manner as [5]. Experimental results were compared with the proposed algorithm [5]. Number of blocks has been increased by 5%, the power consumption was reduced by 3%.

        독립형 하이브리드 가로등의 BESS 연구

        김재진 (사)디지털산업정보학회 2019 디지털산업정보학회논문지 Vol.15 No.4

        In this paper, we study the BESS of a standalone hybrid street light. The proposed BESS proposed a BESS with the function of efficiently charging irregularly generated power from two or more generators. AC generated by wind power is converted to DC using an AC / DC converter and then to a voltage that can charge the battery through the DC / DC converter. The lack of voltage and current, which is a disadvantage of the MPPT method used in solar power generation, is compensated by the DC value of wind power generation. The compensation method is to convert the DC generated from solar power into a voltage suitable for charging the battery through a DC / DC converter, and then connect the DC generated in wind power in parallel to compensate for the insufficient current to charge the battery in a short time. Allow this to begin. By securing the maximum charging time, the usage time of the stand-alone hybrid street light is huge. Experimental results show that the battery has a short charging time and can be efficiently applied to battery-dependent standalone hybrid street lights.

        광고모델 유형에 따른 광고효과: 인식적 반응을 중심으로

        김재진,박미령 한국경영교육학회 2011 경영교육연구 Vol.26 No.4

        The research was investigated the effectiveness of advertisements utilizing the type of endorsers focusing on cognitive responses. The purposes of this paper are as follows: Firstly, we analyze the differences in the cognitive responses by four types of endorsers. Secondly, we review the role of involvement as moderator by four types of endorsers in consumer reponses. Thirdly, we analyze the relationship between the cognitive responses and the attitude toward the brand. We surveyed 192 college students who viewed a fictitious ad. for the shampoo. The data was compiled from 192 questionnaires. 200 questionnaires were collected, but some of the data was considered unsuitable and inappropriate. A total of 105 respondents in high involvement and 87 respondents in low involvement categories were exposed to the advertisements of a shampoo utilizing four types of endorsers. One-way ANOVA was conducted to examine hypotheses. The results of the study showed that the group of high involvement showed the significant difference between a celebrity endorser and a typical female university student endorser among the four types of endorsers in the cognitive responses. The group of low involvement didn't show the significant difference among the four types of endorsers in the cognitive responses. The group of high involvement showed the significant differences both between a professional expert endorser and a celebrity endorser, a professional expert endorser and a chief executive officer endorser among the four types of endorsers in the attitude toward brand. The group of low involvement also showed the significant difference between a professional expert endorser and a typical female university student endorser among the four types of endorsers in the attitude toward brand. Simple regression analysis was conducted to examine the last hypothesis. The results showed that the cognitive responses had impact on the attitude toward brand. In addition, MANOVA was conducted to test interaction effects between the endorser types and involvement. The results showed that there were interaction effects between the four types of endorsers and involvement in the cognitive responses and the attitude toward brand. Those mean there were significant differences in the cognitive responses and the attitude toward brand by four types of endorsers when involvement was considered. 본 연구는 샴푸광고 노출이 네 가지 광고모델 유형별로 소비자의 관여도 수준에 따라 광고효과에 미치는 영향에 대해 살펴보고자 하였다. 광고모델 유형에 따른 차이를 분석하는 방법으로 인식적 반응 접근법을 사용하였다. 구체적으로, 기존문헌을 통해 광고모델 유형, 관여도 및 인식적 반응을 고찰하고, 광고모델 유형별 소비자 반응에서 관여도의 조절적 역할을 실증 분석하며, 브랜드 태도에 대한 인식적 반응의 영향을 검증하고자 하였다. 이러한 목적하에 실험한 결과 본 연구의 발견점들로는 첫째, 관여도에 따른 광고모델 유형별과 인식적 반응 간의 차이는 고관여도 집단의 경우 유명인 모델과 일반여대생 모델 간의 차이가 유의하게 나타났다. 반면 저관여도 집단의 경우 광고모델 유형별 인식적 반응의 차이는 유의하지 않는 것으로 나타났다. 둘째, 관여도에 따른 광고모델 유형별 브랜드 태도 간의 차이는 고관여도 집단의 경우 전문가 모델은 유명인 모델과 최고경영자 모델 간에 차이가 있는 것으로 나타났다. 그리고 저관여도 집단의 경우 전문가 모델과 일반여대생 모델 간에 큰 차이가 있는 것으로 나타났다. 셋째, 인식적 반응과 브랜드 태도는 상관관계가 있으며, 인식적 반응이 브랜드 태도에 긍정적인 영향을 주는 것으로 나타났다. 마지막으로 상관관계가 있는 두 종속변수 인식적 반응과 브랜드 태도를 함께 고려한 다변량 검정에서는 상호작용이 유의한 것으로 확인되었다. 이러한 결과를 통해 인식적 반응 및 브랜드 태도는 관여도가 높을 경우에는 유명인 모델이 호의적인 인식적 반응을 일으키는데 매우 효과적임을 알 수 있었다. 이이 비해 관여도가 낮을 경우에는 최고경영자 모델이나 일반여대생 모델보다 전문가 모델이 호의적인 브랜드 태도에 매우 효과적임을 알 수 있었다.

        At‐Line Raman Spectroscopy Determination of Tablet Mass Gains during the Tablet Coating Process

        김재진,임영일,한장희,우영아 대한화학회 2018 Bulletin of the Korean Chemical Society Vol.39 No.6

        The coating process in the manufacturing of solid dosage forms is important for optimizing therapeutic efficacy because the coating is vital for controlling the drug release rate. The coating is most commonly applied by spraying a solution containing the coating material to form a film. In this study, core tablet samples were collected at regular intervals from four batches made using a scale?up manufacturing coating process, and the Raman spectra were obtained to determine the mass increase of the coated tablets. To acquire the spectra, a wide area illumination scheme was used to sample a large area (28.3 mm2) with a 785?nm laser. Additionally, we established a calibration model using the Raman spectra of three tablet batches and verified the accuracy of the model by predicting the tablet weights of a fourth batch. All spectra were preprocessed with baseline correction and normalization. The spectral range was 1700 to 300 cm?1, and partial least squares analysis was performed to establish a model with full cross?validation. The accuracy was assessed by comparing the difference between the predicted weights using the model and that measured on an analytical balance, which was the reference test method. Standard error of cross?validation (SECV) values and standard error of prediction (SEP) values for the fourth batch were 0.0023 and 0.0020 g, respectively, showing high accuracy. We established four optimal models that encompassed all combinations of different batches in a workplace environment and verified them by predicting each of the remaining batches.
