메를로-퐁티의 살 존재론에 관한 소고(小考) : 그 과정. 구체성과 실존성의 상호 지지관계를 통한 이해

한우섭 ( Woosub Han ) 한국현대유럽철학회 2023 현대유럽철학연구 Vol.- No.70

이 글은 ‘생동적 현재에 대한 존재론적 해명’이라는 살에 대한 레토릭 외부에서 살에 대한 해명 난망의 원인을 다룬다. 이를 위해, 먼저 메를로-퐁티의 철학에서 살 개념이 요구되는 이유를 밝힌 후, 그가 존재론과 형이상학을 구분하고 있다는 것, 나아가 존재론을 형이상학 너머에 위치시키고자 했던 기획이 그가 말하는 ‘새로운 존재론’적 기획이라는 사실을 주장할 것이다. 그 과정에서 본 논문은 다음과 같은 주장을 또한 전개한다. 살 해석의 어려움은 살 개념 자체의 고유한 성격으로부터 기인하기도 하지만, 동시에 그가 펼치는 살에 대한 해명이 지각의 현상학적 기획에서의 구체성과 실존성 사이의 구도를 더는 유지하지 않기 때문이다. 본 논문에서는 그 원인을 다음과 같이 파악한다. 살의 존재론은 그것이 지각의 현상학적 목적의 심화인 한, 지각의 현상학적 기획으로부터 유리되지 않는다. 이때 그 기획은 후설과 하이데거의 현상학적 전통을 유지한다. 그러나 동시에 그것은 지각의 현상학적 작업으로부터 유리되기도 하는데, 이는 내재성의 심화를 향해 펼쳐진 결과 살 존재에 부여된 보편적 성질로부터 기인한다. 본 논문은 살의 현상학적 존재론의 성격은 살이라는 보편 존재의 모순성이 이른바 살에 대한 ‘생생한 기술’로 얼마만큼 ‘해명’될 수 있는가로 판단될 수 있으며, 그 정도에 따라 살 철학의 정체성이 결정됨을 주장한다. This article discusses the cause of the difficulty in clarifying the meaning of the flesh outside of the rhetoric of “ontological elucidation of the living present.” To this end, after having first specified why the concept of flesh imposes itself on the philosophy of Merleau-Ponty, we claim that he distinguishes ontology and metaphysics and that the project of placing ontology beyond metaphysics is what he calls a “new ontology” project. In the process, we learn the following facts: The difficulty of interpreting the flesh is attributed to the singularity of the concept of the flesh itself and, at the same time, it is because its explanation of the flesh no longer maintains the structure between concreteness and existentiality in the phenomenological project of perception. In this article, the case is argued as follows: The ontology of the flesh is not disconnected from the phenomenological project of perception in the sense that it deepens the phenomenology of perception. At this stage, the project maintains the phenomenological tradition of Husserl and Heidegger. However, at the same time, it is disconnected from the phenomenological work of perception, which relates to the nature of the flesh that must be both immanent and universal. Ultimately, the elucidation of the flesh can be judged by the extent to which the contradiction of the flesh can be “described vividly.”

In this research, reliability based design optimization(RBDO) is presented for truss structure. Deterministic and stochastic optimum design are compared for the truss structure. FORM(First Order Reliability Method) is used for stochastic optimum design considering probabilistic distribution for the length of vertical beams. Response surface method(RSM) is utilized to approximate the design functions in the presented procedure.

차량 다중최적화문제시 NVH 성능을 고려한 경량화 사례

한우섭(Woosub Han),박광서(Kwangseo Park) 한국자동차공학회 2011 한국자동차공학회 학술대회 및 전시회 Vol.2011 No.11

As recent consumers require a lean burn vehicle, the importance of vehicle body mass saving is highlighted more. However, if we consider only mass saving in vehicle development, the performance of vehicle can generate a lot of issues. Therefore, we should consider crash, NVH, durability, formability etc for mass saving of vehicle. For realizing that, we carried out structural CAE based on MDO(Multi Disciplinary Optimization) in vehicle design. In order to get a feasible solution through optimization process, single number matrics of the performance levels about each loadcase are required. But, single number matrics for NVH loadcase are not easily defined because of getting a performance curve along frequency to results. Therefore, I will introduce mass saving case through MDO process considering NVH performance effectively in this paper.

The optical characteristics of a terahertz (THz) antenna-coupled bolometer (ACB) detector were evaluated using a pulsed quantum cascade laser (QCL) and radiation blackbody sources. We investigated a method for measuring the responsivity and noise-equivalent power (NEP) of the THz detector using two different types of light sources. When using a QCL source with a frequency of 3 THz, the average responsivity of 24 devices was 1.44×10³ V/W and the average NEP of those devices was 3.33×10^-9 W/√Hz. The average responsivity and NEP as measured by blackbody source were 1.79×10⁵ V/W and 6.51×10^-11 W/√Hz, respectively, with the measured values varying depending on the light source. This was because the output power of each light source was different, with the laser source being driven by a pulse type wave and the blackbody source being driven by a continuous wave. The power input to the THz sensor was also different. Futhermore, the responsivity and NEP values measured using band pass filter (BPF) were similar to those measured when using only THz windows. It was found that ACB sensor responds normally in the THz region to both the laser and the blackbody source, and the method was confirmed to effectively evaluate the characteristics of the THz sensor.

In deterministic optimization, engineering designs are often driven to the limits of the design constraints, leaving little or no latitude for tolerances in modeling and simulation uncertainties and/or manufacturing process variability. Optimized designs determined without due consideration of tolerances can be unreliable leading to catastrophic failure. A reliability-based design optimization (RBDO) method that enable the determination of optimum designs that incorporate confidence ranges for mechanical system is studied. RSM method is utilized to approximate the design functions in the presented procedure. The proposed method is applied to the car body structures for reliability based optimal design.<br/>

Objective: The aim of this study is to develop a human error classification framework for chemical facilities and to apply it to major industrial accidents in chemical facilities in Korea. Background: Human errors can be classified with various criteria such as human information processing procedure by which the error was caused, explicit form of the error behaviour, and the consequence of the error. Method: Three human error classification criteria was chosen to classify human errors in major industrial accidents in chemical facilities: active vs. latent errors, external (behavior-based) classification, and internal (information processing-based) classification. Major industrial accidents which occurred in chemical facilities in Korea from 1997 to 2011 were analysed. Results: A total of 177 human errors were identified from 85 accident cases, and classified using the three criteria. Conclusion: Change in the number of human errors and frequencies of related facilities and industries were analysed. Application: The results provide insight on the pattern of human errors related to major industrial accidents in chemical facilities. In addition, they suggest that the accident investigation protocol is need to be improved.

This study examines the current status of liberal arts major education that has been attempted since the 2000s, seeks the realization direction of liberal arts major education in Korea, and explores practical models focusing on the case of J University located in the province. The purpose of this study was to discuss the significance and feasibility of the liberal arts major presented as a new alternative in the crisis situation of the university, focusing on actual cases. Attempts to realize liberal arts major education have been made at home and abroad, paying attention to the possibility of liberal arts that can develop essential abilities with perseverance despite the changes of the times, but no effective plan has been proposed. Therefore, in this study, based on the consideration of domestic and foreign cases and the actual situation of J University, I tried to come up with a more practical way of realizing liberal arts major education.
