The purpose of this study is an application of Lee's Menu Engineering (LME) method for menu analysis on the eight kinds of pizza selected from 17 kinds of pizza served by an Italian restaurant near by the Keimyung College University campus. The eliminated nine items were in the third quadrant or below the trend line. The LME method is more efficient than generally used methods such as the Miller, Kasavana & Smith, Uman, Pavesic and Merricks & Jones method. The LME method comprises reference lines and four quadrants created by x, y axes and its average values. The x and y axes comprise the sales ratio (MM%, percentage of the Menu Mix) and the weighted contribution margin (WCM%, percentage of the Weighted Contribution Margin) respectively. The obtained results are such that total sales increased by 1.59% from 58,747,200 won to 59,684,000 won, despite the decrease in sales volume. Total contribution margin also increased from 35,248,320 won to 35,810,400 won. The trend line also shows from y=0.9147x (R²=0.703) to y=0.9944x (R²=0.9893). These results indicate that the LME method is superior in practical applications.

The purpose of this study was to measure concentrations of $K^+$, $Na^+$, $Cl^-$ by ionometer with check salt strip, simple salimeter and Ion-selective electrode (ISE) and compare the results of each mensuration; furthermore, the possibility of inferring the $Na^+$ concentration from $Cl^-$ concentration of urine and the impact of $K^+$ on the concentration of each ion was examined. The results showed that ISE determined $Na^+$ and $Cl^-$ concentrations in the urine are highly interrelated (R=0.9039); in addition, concentrations of $Cl^-$, measured with strip and ISE from urine are highly interrelated (R=0.9338). The concentration of $Na^+$ in urine, inferred by measuring $Cl^-$ concentration with strip, has a high relationship (R=0.8580) with the concentration of $Na^+$ in urine, measured by ISE. The results of our study will increase awareness of $Na^+$ intake and the utility of check salt strip, as well as the possibility of inferred $Na^+$ concentration from measures of $Cl^-$ concentration as a screening test for reducing sodium intake.

Local wall thinning and integrity degradation caused by several mechanisms, such as flow accelerated corrosion, cavitation, flashing and/or liquid droplet impingement, is a main concern in secondary steam cycle piping system of nuclear power plants in terms of safety and operability. Thinned pipe management program (TPMP) has being developed and optimized to reduce the possibility of unplanned shutdown and/or power reduction due to pipe failure caused by wall thinning. In this paper, newest technologies, standards and regulations related to the integrity assessment, repair and replacement of thinned pipe component are reviewed. And technical improvement items in TPMP to secure the reliability and effectiveness are also presented.

제품디자인에서 미적 표현형식으로서 움직임의 사례 -모리스 메를로 풍티의 지각에 근거하여-

이성호,Lee, Sungho 한국스마트미디어학회 2014 스마트미디어저널 Vol.3 No.3

메를로 퐁티의 지각에 근거하여 본 연구자는 움직임을 제품에 구조화된 고유한 미적 성질과 표현 그리고 가치가 통합되어 의미, 즐거움을 체험하는 형식으로 규정했다. 본 연구의 목적은 웨어러블, 유비쿼터스, 인터랙션, 놀이, D.I.Y, 유니버셜, 에콜로지는 이 움직임이 다양하게 제품디자인에 주제화된 형식, 양상임을 주장하는 것이다. 이는 움직임과 모든 디자인형식들 사이의 다음과 같은 유비추론의 방법과 형식에 따라 판단된 결과이다. 첫 번째, 움직임은 미적 표현과 가치의 통합으로써 미적 판단의 근본적, 보편적 명제, 공리다. 두 번째, 모든 디자인형식들은 미적 표현체계에 근거한 가치가 주제화된 사례다. 세 번째, 따라서 모든 디자인형식들은 미적 가치에 의거한 표현의 양상이다. 이상과 같은 판단, 추론의 확실성은 미적 표현으로서 움직임과 디자인형식 사이의 일치가 사실이라는 증명이다. 즉, 미적 가치가 연구된 모든 디자인형식들에서 주제로 성립하여 사용자가 실제로 미적 의미, 즐거움을 체험하였음에 대한 증명이다. 이에 대한 보증은 사용자의 생활 속에서 개개인의 체험이 유일하다. 움직임은 제품의 존재, 사용자의 당위를 미적(실천적) 차원에서 통합함과 동시에 이에 근거해 성립한다. 본 연구의 모든 연구사례에서 강조되는 것은 제품이 아니라 움직임이다. 따라서 제품디자인은 이러한 움직임을 제품에 구조화하는 활동으로 전환된다. Based on the perception of Maurice Merleau Ponty, This study defines that Moving is a form lively to experience meaning, pleasure as the aesthetic attribute structured to a product, expression and value are synthesized into. The purpose of study is to argue that Wearable, Ubiquitous, Interaction, Play, D, I, Y, Universal, Ecology are the forms, modalities that the moving is variously subjected to the product design. Above This is the result reasoned according to analogical form as below between the moving and all design forms. First, The moving as the aesthetic expression and value are synthesized into is the intrinsic, general proposition, maxim for the value judgement. Second, All design forms are the cases which the values based on the aesthetic expression system are subjected to Third, Thus All design forms are the modalities of the aesthetic expression based on the values. The certainty of this judgement, reasoning is the proof that the correspondence between the moving as the aesthetic expression and design form is the fact. That is to say, It is the proof that Users lively experience the aesthetic meaning, pleasure in fact as the aesthetic values are subjected to all design forms. The lived experience of each user in their daily life itself is the only method or assurance for this. The moving integrates the existence of a product and what should be of users into the aesthetic dimension and at the same time, is realized based on this. The emphasized theme in all cases of this study is not the product but the moving. So, The product design is changed into the action which structures the moving like above to a product.

무선광시스템에서 광섬유 커플러를 이용한 잡음광의 영향 감소

이성호,Lee Seong-Ho 한국전자파학회 2005 한국전자파학회논문지 Vol.16 No.5

In this paper, optical noise is reduced by a differential detector with an optical fiber coupler in an optical wireless system. An $1\times2$ optical fiber coupler divides the received optical signal by 2 equally, and connects them to the two photodiodes in a differential detector. The output voltage variation due to the abrupt change of optical noise distribution in space disappears because the two photodiodes effectively detect the optical signal at the same point. The signal to noise ratio in a differential detector with a fiber coupler was 8 dB higher than in a single photodiode with an optical filter. 본 논문에서는 광섬유 커플러를 이용하여 차동 검출기를 구성하고 무선광시스템에서 잡음광 소거에 활용하였다. $1\times2$광섬유 커플러를 이용하여 수신광을 2개로 분리해서 수신하면 동일한 지점의 잡음광을 2개의 포토다이오드에서 동시에 검출하는 효과가 발생한다. 따라서 잡음광의 공간분포의 변화가 심하게 발생하는 환경에서도 2개의 포토다이오드의 위치 차이로 인한 출력 전압의 변동이 나타나지 않아 잡음 소거 효과가 높아진다. 광필터를 사용한 단일의 광검출기에 비하여 광섬유 커플러를 사용한 차동검출기에서 신호대 잡음비를 약 8 dB 개선하였다.

플라스틱 광섬유를 이용한 무선광 차동검출기의 신호대잡음비 개선

이성호,Lee Seong-Ho 한국전자파학회 2005 한국전자파학회논문지 Vol.16 No.4

본 논문에서는 플라스틱 광섬유 묶음을 이용하여 차동검출기를 구성하고 무선광 연결 수신부에서 잡음광 소거에 활용하였다. 광섬유 묶음을 이용하여 수신광을 분리해서 2개의 포토다이오드에 연결하면, 동일한 지점에서 잡음광을 검출하는 효과가 발생하므로, 잡음광의 공간분포가 심하게 변하여도 2개의 포토다이오드의 위치 차이로 인한 출력 전압의 변동이 나타나지 않아 잡음 소거 효과가 높아진다. 광 필터가 부착된 단일의 광검출기에 비하여 광섬유 묶음을 사용한 수신부에서 신호대잡음비를 약 $10\;\cal{dB}$ 개선하였다. In this paper, optical noise is reduced by a differential detector with a plastic optical fiber bundle in a wireless optical interconnection. A plastic optical fiber bundle divides the received optical signal equally and connects it to two photodiodes. In this configuration two photodiodes effectively detect the optical signal at one point, and the output voltage variation due to the abrupt change of optical noise distribution in space disappears. The signal to noise ratio in a differential detector with a fiber bundle was improved to be $10\;\cal{dB}$ higher than in a single photodiode with an optical filter.

N/A High-level wastes contain significant quantities of platinum group metals such as palladium, ruthenium, and rhodium. These metals are used for catalystic process, electronic and electrochemical industries, anti-corrosion alloys, dental applications etc. The demand of noble metals continues to grow in a steady manner. Many techniques for separation and recovery of the platinum group metals have been studied. In this paper, batch experiments were carried out to investigate ion exchange characteristics of platinum group metals by commercial anion exchange resins such as IRN 78 and Dowex 1x8. The effects of ionic group of resins, solution temperature, co-ions, and the concentration of nitric acid were investigated.

유도결합 RFID 시스템에서 이중 코일 안테나를 이용한 잡음의 감소

이성호,Lee, Seong-Ho 한국전자파학회 2007 한국전자파학회논문지 Vol.18 No.6

본 논문에서는 유도결합을 이용한 RFID 시스템에서 주변의 RF 잡음의 영향을 감소할 수 있는 이중 코일 안테나를 새로이 제안하고 실험하였다. 이중 코일 안테나는 동일한 구조의 코일 2개가 직렬로 연결되어 있으며 두 코일에 유도되는 잡음 전압의 크기가 같고 극성이 반대가 되어 서로 상쇄되도록 고안된 구조이다. RFID 리더에 이중 코일 안테나를 사용한 경우에 단일 코일 안테나에 비하여 RF 유도 잡음이 약 15 dB 감소하였다. In this paper, we introduce a dual coil antenna which is useful for reducing the effects of radio frequency noise in an RFID system. A dual coil antenna is composed of two identical coils that are connected in series. The noise voltages in the two coils almost disappear when they are added because the magnitudes are equal and the polarities are opposite. The noise in an RFID reader with a dual coil antenna was 15 dB lower than that with a single coil antenna.
