The aims this paper to examine Nietzsche's criticism on Paul's transvaluation of values. First, I will examine Socrates' transvaluation of values through which, Greek culture was deconstructed. He opened a path for the transvaluation of values before Paul and Nietzsche and reorganized Greek culture around his own values. I will also analyze the 'will to power' hidden behind Socrates' transvaluation of values. Second, I will examine the essence of the Paul's transvaluation of values. I will trace how Paul, through his transvaluation of values, could become the center of Christianity and, in turn, control European Culture. I will also show the difference between the teachings of Jesus and the arguments of Paul. Third, I will look at the Nietzsche's criticism on Paul's transvaluation of values. The key to Nietzsche's criticism on Paul is to evaluate Paul's transvaluation of values in terms of his will to power. And I will also look at the problems of Nietzsche's criticism on Paul. Fourth, I will look at Nietzsche's transvaluation of values. It is accomplished in such a way that he makes Socrates' and Paul's transvaluation of value alters. His transvaluation of values will be critically examined for strength in life and world understanding over Socrates' and Paul's transvaluation of values.

최근 IT(Information Technology)가 결합된 스마트 섬유의 수요가 꾸준히 증가하고 있다. 생활수준 향상에 따른 유저들의 청결, 쾌적에 대한 높은 관심속에서 생활 및 의료용 섬유에도 다양한 기능성이 요구되어지고 있다. 초경량, 흡한속건, 투습방수 등 레저 스포츠, 아웃도어 활동에 필요한 고기능성 소재는 제품의 고부가가치를 더하는 가치 상승 요인이긴 하지만 그 기술과 적용성이 이미 포화 상태에 도달했다고 볼 수 있다. 이에 국내 외 섬유 업체들은 스마트 섬유 열풍을 큰 기회로 삼아 헬스케어 기능, 엔터테인먼트 기능 등의 최첨단 기술과 결합되어진 특화된 섬유시장을 통해 더 높은 부가가치를 창출하고 새로운 섬유시장의 도약을 노리고 있다. 이에 본 연구에서는 위치추적이나 동선, 생체적 리듬 등을 파악할 수 있는 스마트 섬유용 전도성 섬유센서의 초기특성(전기적, 물리적 물성)을 유지함과 동시에 심미적인 효과와 새로운 기능성을 부여하기 위하여 전도성 센서소재의 최적 선염공정을 조사하고 외부적인 환경변화를 염두에 두어 그 물성 변화를 측정하였다.

The production period of Daedongyeojijeondo is estimated from 1861 to 1866 in consideration of place names. Daedongyeojijeondo is elaborated enough that there are the latest data in, especially is better than Haejwajeondo that is a representative map in the 19th century in marking distance. Daedongyeojido is an official map for national defense and administration, on the other hand Daedongyeojijeondo is a popular map in which social and economical contents are included. The recognition of mountains and rivers based on organic view of the land is also represented in Daedongyeojijeondo, and the principle of the whole of mountains and rivers is well reflected. It is far better than modem maps in the expression of road system and distances, tidal area in rivers.

The amount of digital data a is explosively growing, and these data have large potential values. Countries and companies are creating various added values from vast amounts of data, and are making a lot of investments in data analysis techniques. The privacy problem that occurs in data analysis is a major factor that hinders data utilization. Recently, as privacy violation attacks on neural network models have been proposed. researches on artificial neural network technology that preserves privacy is required. Therefore, various privacy preserving artificial neural network technologies have been studied in the field of differential privacy that ensures strict privacy. However, there are problems that the balance between the accuracy of the neural network model and the privacy budget is not appropriate. In this paper, we study differential privacy techniques that preserve the performance of a model within a given privacy budget and is resistant to model inversion attacks. Also, we analyze the resistance of model inversion attack according to privacy preservation strength.

고분자연료전지(PEMFC)에서 기체확산층(GDL)은 다공성의 카본 종이/천 위에 마이크로한 다공층을 가치는 구조로 촉매층을 지지하고 촉매층과 분리판 사이의 전류전도체 역할을 한다. 또한 촉매층에 연료와 공기 확산 및 생성된 물의 통로 역할을 하며 소수성인 전기전도성 물질로 이루어져 있다. 현재 연료전지에 쓰이는 가스확산층은 대부분 국외 회사에서 제조 수입 사용하는 현황이고 국내에서는 협진 I&C가 연구하고 있으나 상용화는 아직 이루어지지 않고 있다. 본 연구는 탄소섬유의 전도성을 개선하고자 탄소섬유 표면에 금속코팅 시 최적의 접촉계면유지를 위한 표면처리 방법 및 공정을 조사 분석 후 최적 개선방법(농도/온도/압력/시간)을 설정하고자 하였다. 또한 선정된 공정인자별 수준별 시험 후 샘플링 된 시료를 토대로 금속물질이 탄소섬유 표면에 코팅(도금)된 금속-탄소섬유를 대하여 평가하여 최적화시키고자 탄소섬유로부터 carbon paper GDL의 모재를 개발할 계획이다. 앞에서 설명한 바와 같이 탄소섬유를 이용하여 paper making, resin impregnation, molding, carbonization/graphitization의 제조공정을 거쳐 paper형태의 GDL을 생산 및 평가하고자 하였다.

The recycling of waste resources, such as spent catalysts, primarily involves leaching and extracting metal components via smelting. These metal components are then recovered as salts, such as sulfates and nitrates. When crystallization occurs during the calcination of the recovered salts, the salts are converted into oxides, which are then reduced to form metals or ceramic materials. Common reducing agents used in oxide reduction include hydrogen and carbon, and metal powders are obtained upon reduction. Carbide synthesis can occur if the recycled element is a transition metal and carbon is used as the reducing agent. Despite being ceramic materials, transition metal carbides exhibit excellent conductivity owing to their metallic bonding. Recently, MXene, a two-dimensional transition metal carbide, has gained attention for electromagnetic wave shielding, secondary battery electrodes, and water purification owing to its electrical conductivity and large surface area. This study developed a process for synthesizing high-value MXene materials from waste resources. The properties of these MXenes were evaluated to confirm the potential of using waste resources as raw materials for MXenes.

The coconut shell, a by-product of popular tropical fruit, is a promising material due to its interesting properties. The preparation of the composite consisted of conducting polymer and coconut shell using a simple wet method, and subsequent carbonization produced a carbonized material under a controlled carbonization cycle. In addition, its electrochemical performance as an anode in lithium-ion batteries was also investigated. The appearance of the obtained materials was observed with a scanning electron microscope. The internal structure of the carbon derived from the coconut shell under a controlled heating profile was analyzed using a Raman spectroscope. A simple electrical measurement based on the ohmic relationship showed that the carbonized product has a significant electrical conductivity. The application of the carbonized product as anode in a lithium-ion battery was tested using half-cell charge/discharge experiments. This article provides important information for future research regarding the recycling of fruit shells and food waste.

The Toyo Bunko (東洋文庫) in Tokyo, Japan is one of the largest library that holds the Korean old geographical documents. About 200 topographies of counties and prefectures, including Giinhansangnyang 杞人間商量 which recorded compilation and improvement plan of the geographical annals belong to it. Several maps and geographical annals of Joseon Period possessed in the Toyo Bunko are set high values on geography since the materials are only belong to it and have not yet been found in Korea. There are very important map collections including six copies of Daedongyeojido 大東輿地圖(1861, 1864) by Kim Jeongho(金正浩) and Suseonjeondo 首善全圖 by Kim, Jungho, collectible stamp of Maema Kyosaku(前間恭作) is imprinted on it, and Gangyeokjundo 疆域全圖 and Dongyeodo 東輿圖 which made with 20-ri and 10-ri grid, owned by Sidehara Daira(幣原坦). Especially Gwanbukjido 關北地圖 which is the northern border map recorded the Lee Sam's(李森) preface who served as a military official of Hamgyeong and Pyeongan Province in early 18th century. These maps and some other maps have a historical value to supplement of the history of Korean Cartography.

SiC는 wide bandgap 물질로서 그 material properties로 인하여, high tmperature, high power, high frequency영역으로의 사용이 기대되는 물질이다. 따라서 SiC에 대한 기본적인 연구와 더불어, 그 소자 제작 및 응용에의 연구가 절실한 시점이다. 이에, SiC 기본적인 소자중 하나인 Schottky diode에 대해 연구하였다. 본 논문은 Schottky contact 물질로써 현재까지 연구가 미비한 Ru을 사용하였다. Ru은 Pt 계열물질로써, 다른 metal에 비하여 열역학적으로 안정하며, 또한 그의 산소 화합물인 RuO2는 다른 oxide에 비하여 전도성 이 높은 장점을 가지고 있다. 따라서 Ru-SiC diode는 이러한 측면에서 연구할 만한 가치가 있다.

CJ제일제당 안산공장은 전당과 전분당 등을 생산하고 있는 식품소재 제조사업장이다. 업종 특성상 폭발 등의 사고가 일어날 수 있고, 전도, 협착, 추락 등의 재해 발생 가능성도 높은 편이다. 실제로 이곳은 지난 2007까지 매년 사고가 발생하면서 골머리를 앓았다. 밀폐된 공간에서의 사망사고, 협착사고, 추락사고, 지게차 사고 등 사고유형도 다양했다. 하지만 지금 이곳은 무재해 5배수 기록을 달성한 사업장으로 지역사회에 큰 귀감이 되고 있다. KOSHA18001 인증, PSM 인증 등 안전시스템 구축과 교육체계의 확립, 안전관리자의 열정, 그리고 한번 해보자는 임직원들의 관심 어린 참여가 어우러져 나타난 결과다. 여기에 한 가지 더. 이곳이 무재해 사업장으로 자리 잡을 수 있었던 것에는 안세천 공장장의 안전경영이 큰 몫을 했다. 안전에 대한 확고한 신념을 가지고, 안전사고 예방을 철저히 강조하고 있는 안세천 공장장을 만나봤다.
