Objective : The aim of this study was to investigate how trauma and personality system was related by comparing TCI profiles of the trauma versus non-trauma groups and PTSD symptom positive (PTSD symptom [+] group) and PTSD symptom negative groups (PTSD symptom [-] group). Methods : We compared the difference of Temperament and Character Inventory (TCI) profiles between the trauma (n=61) and the non-trauma (n=61) groups, and between the PTSD symptom [+] group (n=40) and PTSD symptom [-] group (n=21). Results : Comparison of the TCI's seven higher dimensions between the PTSD symptom [+] and [-] groups showed significant differences only in C (Cooperativeness). And in the analysis of TCI's lower dimensions the significant differences were observed in the HA1 (Worry and pessimism), HA2 (Tension regarding uncertainty), and C4 (Compassion) subscales. However, significant differences in the higher dimensions appeared more clearly between the non-traumatized group and the traumatized group. Compared to the non-traumatized group, the traumatized group scored significantly higher in HA (Harm avoidance) and RD (Reward dependence), while lower in SD (Self-directedness). Conclusion : Overall, present results suggest that traumatic experiences may affect personality systems regardless of the development and of PTSD symptoms.

맥도웰의 초월적 정당화: 맥도웰-드레퓌스 논쟁을 중심으로

신승민 ( Shin Seung-min ) 서강대학교 철학연구소 2019 철학논집 Vol.56 No.-

이 논문은 인간의 경험과 개념 사이의 영향 관계에 대한 맥도웰-드레퓌스 논쟁을 다룬다. 맥도웰에 의하면 인간의 경험에는 개념적인 능력이 완전히 작용한다. 반면 드레퓌스(H.Dreyfus)는 어떤 경험에는 개념적 능력이 작용한다고는 할 수 있어도, 모든 경험이 그렇다고 할 수는 없다고 비판한다. 필자는 드레퓌스와 쉬어의 비판은 맥도웰이 자신의 주장을 정당화하는 초월적인(transcendental) 방식을 간과하고 있다고 주장한다. 맥도웰의 초월적 정당화의 핵심은 만일 경험에 개념적 능력이 작용하지 않는다면, 마음과 세계가 맺는 규범적 관계가 가능하지 않다는 것이다. 이에 대해 적어도 어떤 경험은 개념적이지 않다고 비판하는 것은, 경험의 개념성이 어떠한 사실이 가능하기 위한 필요조건인지를 제대로 이해하지 못한 것이다. 물론 드레퓌스는 비개념적 경험의 사례들이 궁극적으로 경험을 가능하게 하는 조건을 드러내준다고 주장한다. 하지만 이 사례들은 단지 경험의 인과적인 조건일 뿐, 정당화된 경험적 사유를 구성하는 조건은 아니다. This paper deals with Mcdowell-Dreyfus debate concerning a relationship between a human experience and a concept. Mcdowell says our conceptual capacities are thoroughly operative in human experience, whereas Dreyfus argues that although the conceptual capacities are operative in some experience, it does not follow that all experiences are conceptual. I defend Mcdowell’s position in this paper. I argue Dreyfus and Schear is ignoring the transcendental aspect of Mcdowell’s justification of his own claim. Its core idea is that unless conceptual capacities are operative in experience, a normative relationship between mind and world would be impossible. Objecting this view on the ground at least some experiences are non-conceptual, is not fully understanding how conceptuality of experience makes certain facts possible, of which it is a necessary condition. Of course Dreyfus shows that cases of the non-conceptual experience reveals the very condition of possibility of experience ultimately. However, those cases are merely causal condition of the experience, not the constitutive condition of a ‘justified’ empirical thought.

Mesothelioma is a rare aggressive tumor arising from the mesothelial cell and regarded as universally fatal disease with average survival around 1 year. The incidence rate is varied from one to forty per million in different countries and increasing by the year. The most common site of tumor origin is the pleura and only 20% to 33% of mesothelioma arise from the peritoneum. There are increasing reports of malignant mesothelioma with forty to fifty fatal cases per year in Korea. Histological studies with immunohistochemical stain is helpful for the diagnosis of peritoneal mesothelioma and imaging modality alone is not sufficient for diagnosis, so it is difficult to confirm diagnosis. A 64-year-old male patient was admitted to the hospital with a palpable mass on abdomen. The 6×6 cm sized huge mass was seen on the body of stomach adjacent to the peritoneum. We report a case of malignant peritoneal mesothelioma without evident exposure to asbestos, of which direct invasion to the gastric mucosa was confirmed by endoscopic biopsy and immunohistochemical stain.

Google provides mapping services using satellite imagery, this is widely used for the study. Since about 20 years ago, research and business using drones have been expanding. Pix4D is widely used to create 3D information models using drones. This study compared the distance error by comparing the result of the road construction site with the DSM data of Google Earth and Pix4 D. Through this, we tried to understand the reliability of the result of distance measurement in Google Earth. A DTM result of 3.08 cm/pixel was obtained as a result of matching with 49666 key points for each image. The length and altitude of Pix4D and Google Earth were measured and compared using the obtained PCD. As a result, the average error of the distance based on the data of Pix4D was measured to be 0.68 m, confirming that the error was relatively small. As a result of measuring the altitude of Google Earth and Pix4D and comparing them, it was confirmed that the maximum error was 83.214m, which was measured using satellite images, but the error was quite large and there was inaccuracy. Through this, it was confirmed that there are difficulties in analyzing and acquiring data at road construction sites using Google Earth, and the result was obtained that point cloud data using drones is necessary.

As a new initiative, Hyundai Motor Company diversified into luxury automobile market by creating a new company brand called “The Genesis”. However, there is nothing new about this attempt. Honda, Nissan and Toyota motor companies have all diversified into luxury market by creating Acura, Infiniti, and Lexus, respectively. This effort, as history has proven, imposed significant restriction in terms of supply chain management. This restriction is leads to possible insolvency issues leading to financial and supply chain restrictions in long term. Upon these issues, this study focuses on productivity change before the diversification and after. As shown in the Japanese car makers, Honda and Nissan have been damaged and affected by poor productivity for 10 years. Tangible asset and number of employees have largely increased without efficiency. Instead, Toyota has efficiently managed productivity. By using module-type production, Hyundai is not guaranteed the productivity increase in the luxury diversification. Hence, this study shows that it will not be difficult to see productivity decrease in this Hyundai’s endeavor.

본 논문에서는 광대역 특성을 갖는 잡음 환경에서 전파 배경 잡음 측정 시스템의 효과적인 측정을 위한 백색 가우시안 잡음 대역 선정 방법을 제안한다. 산업기기들로부터 발생하는 인공 잡음은 주로 광대역으로 발생하는 임펄스성 잡음으로 현대 잡음 레벨 증가의 주 요소이다. 기존의 특이값 분해에 기반한 방법은 주로 백색 스펙트럼 성질에 기초하여 판별하는 방법으로 광대역 신호에 대하여 그 성능을 효과적으로 내지 못하는 단점이 있다. 제안된 방법은 특이값 분해 기반 방법을 가우시안 특성 기반 방법과 병행함으로써 광대역 환경에서도 백색 가우시안 잡음 대역을 효과적으로 판단할 수 있는 성능을 제공한다. 또한, 가우시안 특성 기반 방법으로써 신호강도 확률 분포 그래프 이용 방법이 갖고 있는 판정의 정확도를 개선하는 모델링을 통한 파라미터 추정 기반 방법을 제시하였다. 제안된 방법의 효율성을 입증하기 위하여 실제 측정 시스템에서 획득한 데이터에 적용하여 제안 방법이 광대역 환경에서 기존의 방법에 비하여 우수함을 보였다. In this paper, an effective method has been proposed for selection of white Gaussian noise(WGN) band for radio background noise measurement system under broad band noise environment. MMN which comes from industrial devices and equipment mostly happens in the shape of broad band noise mostly like impulsive noise and this is the main reason for increasing level in the present radio noise measurements. The existing method based on singular value decomposition has weak point that it cannot give good performance for the broad band signal because it uses signal's white property. The proposed method overcomes such a weakness of singular value decomposition based method by using signal's Gaussian property based method in parallel. Moreover, this proposed method hires a modelling based method which uses parameter estimation algorithm like maximum likelihood estimation(MLE) and gives more accurate result than the method using amplitude probability distribution(APD) graph. Experiment results under the natural environment has done to verify feasibility of the proposed method.

The purpose of this study was to investigate the effect of elastic band resistance training on the improvement of balance ability, and gait performance in the elderly. Subjects were between 58 and 67 years of aged elderly women, and were divided into exercise group(n=10) and control group(n=10). The subjects for experimental group were participated in the elastic resistance training program for 8 weeks. Body composition, muscular function, balance ability, and gait performance test were measured, and data were compared using ANOVA with group and time, paired or independent t-test for post hoc. Significances for statistical analyses were set at p< .05. In body composition as body weight, BMI, LBM, and %Body fat, exercise group showed a positive change as compared to control group, but this change was not statistical significance. In balance ability, exercise group showed a positive effect after training, and one-leg stance of exercise group was a significant (p<.05) higher value than control group after training. In leg muscular endurance by leg chair squat test, exercise group was significantly increased(p<.05) after training. Cadence of temporal distance gait performance test showed a positive effect of training in exercise group. In conclusion, elastic resistance training has a very positive effect to improve balance ability, leg muscular endurance and gait performance.
