Harmonie du Soir 의 잉여소 분석

채희성(Hi Seng Chae) 한국프랑스학회 1987 한국프랑스학논집 Vol.13 No.-

Au point du vue des pomes traditionnels, des redondances (ex. former, rimes, mots redondants, sons, etc. ) ne sont que des methodes simples et subordonnes pour exprimer des significations des pomes. Mais, dans L`Harmonie du soir, des redondances ont les significations particulii`res, c`est-a-dire, significations modernes. Cette article a but d`eclairer les modernites de H par 1`analyse des redondances. Notre analyse a donc les etapes suivantes. En premier lieu, nous definissons les mots subjectifs et les mots redondants, les elements subjectifs et les elements redondants (non-elements subjectifs). En deuxime lieu, nous examinons la forme du pantoum traditionnel et de H, et les significations formelles. En troisime lieu, nous examinons la dependance des vers et demi-vers, et leurx poeticites. En quatrime lieu, nous examinons la dependance des mots redondants, et destruction des mots subjectifs (souvenir) et sa primaute. Ici, nous pouvons insister pour que le sujet de H soit 1`atmosph~re d`harmonie, non le souvenir de M Sabatier. Enfin, nous examinons la dependance des sons et leurs poeticite. Il en resulte que H. S a des relations etroites avec la modermite du pocme, car les redondances dans H. S prosduisent les significations poetique ainsi que les elements subjectifs.

서비스 지향적인 효율적인 클러스터 서버 구축 및 관리

Modern server systems are usually composed in the form of cluster systems in order to serve not only as many users but also as many kinds of applications as possible. The progression of the cluster system architecture leads in a middleware approach based on the Java framework. The middleware approach alleviates the efforts for the construction and the management of a server system but still preserves its performance and applications on the server. In this research, we introduce a new clustering scheme for the easy construction and maintenance of a cluster server system with the Java Management Extensions. We first demonstrate the construction and configuration process. Our experiment sets can verify that it is easy to construct, expand and manage a middleware based cluster system as well as the applications which reside on it. In addition, we can achieve reasonable performance on our service oriented clustered system with the help of state-of-the-art middleware. The experimental results of performance demonstration contain the availability of a server, and the effectiveness of load balancing and scheduling mechanisms. Especially, our service oriented scheduling mechanism was shown to successfully manage load imbalance under the normal load and cope with the overloaded situations, compared with other known scheduling mechanisms. 현대의 서버 시스템은 대부분의 경우 클러스터 시스템으로 이루어지어 가능한 많은 사용자를 지원할 뿐만 아니라 가능한 많은 어플리케이션을 지원하는 것을 목적으로 하는 서비스 지향 클러스터 시스템이다. 클러스터 시스템 아키텍쳐의 발전으로 자바 프레임웍에 기반한 미들웨어 어프로치가 발전하고 있다. 미들웨어에 의한 방법은 서버 시스템의 성능과 어플리케이션의 활용도를 보장하면서도 서버 시스템 구축을 위한 대부분의 노력을 덜어준다. 본 연구에서는 JMX를 이용하여 클러스터 시스템의 손쉬운 구현과 관리를 달성할 수 있는 새로운 클러스터 시스템을 소개한다. 일단 클러스터 시스템의 구축과 구성단계를 보이며, 어플리케이션과 시스템 양자에 걸쳐서 손쉬운 구축과 확장, 그리고 관리가 미들웨어에 기반한 시스템에서 이루어짐을 보인다. 덧붙여 서비스 지향 클러스터 시스템이 미들웨어에 기반하여 우수한 성능을 보임을 성능 평가 실험 결과를 통하여 검증하였다. 기본적인 성능 평가 결과는 서버의 가용성, 그리고 로드 밸런싱과 스케쥴링 알고리즘의 효율성을 검증하였다. 특히, 우리의 서비스기반 스케줄링 방법이 정상부하시 적재불균형문제와 과부하시의 대처능력에서 타 방법에 비해 우수함을 보였다.

Sebaceous carcinoma is a relatively rare and aggressive malignant tumor. Periocular area (especially eyelid) is the most common lesion to occur, and the most common extraocular lesion is the parotid gland. Because the lesion also mimic other benign inflammatory diseases, this leads to delayed diagnosis or misdiagnosis. Here, we report a 58-year-old male patient who presented with a non-tender painless left parotid mass after wide excision of sebaceous carcinoma in the left eyelid two years ago. When he was diagnosed with sebaceous carcinoma of left eyelid, there was a small left parotid tumor on the computed tomography. But no further examination and treatment were performed. Two years later, physical examination revealed growing parotid tumor and multiple neck nodes on the left side. After radical parotidectomy and neck dissection, histological examination showed a sebaceous carcinoma and neck node metastasis. Considering the aggressiveness of sebaceous carcinoma, further evaluation for parotid glands should be considered when sebaceous carcinoma of the eyelid was discovered. Postoperative chemoradiotherapy was performed for disease control. Follow up after two years, and computed tomography showed no sign of recurrence.

Mangosteen Extract Attenuates the Metabolic Disorders of High-Fat-Fed Mice by Activating AMPK

This study investigated the effects of mangosteen on metabolic syndromes in high-fat (HF) diet-fed mice and the underlying mechanisms related to adipogenesis. Mangosteen-supplemented mice gained significantly less body weight, compared with the HF group. The levels were markedly elevated in HF mice for serum glutamate oxaloacetate transaminase, glutamate pyruvate transaminase, glucose, triglyceride, total cholesterol, low-density lipoprotein (LDL) cholesterol, and free fatty acid; whereas these levels were significantly lower in the 200 mg/kg of the mangosteen extract-treated group. The mangosteen extract did not modify high-density lipoprotein (HDL)-cholesterol, however, LDL-cholesterol was lower and HDL/LDL ratio was higher (9.4 vs. 3.7 in HF group). Furthermore, 200 mg/kg of mangosteen treatment activated the hepatic AMP-activated protein kinase and Sirtuin 1 in an in vivo system. Thus, the results of this study suggest that mangosteen extract exerts antiobesity effects by regulating energy metabolism and hepatic lipid homeostasis.

Mediating Effect of Meta-cognition between Locus of Control and Self-efficacy

채희성,함상우 국제문화기술진흥원 2018 International Journal of Advanced Culture Technolo Vol.6 No.1

Meta-cognition is the knowledge and cognition of cognitive phenomena, including the control of ones own memory, comprehension, and thought processes. Meta-cognition is similar to self-awareness, which is the understanding of oneself, and affects people’s attitudes and behaviors. This study demonstrated the mediating effect of meta-cognition between internal locus of control and self-efficacy. Internal locus of control refers to the steady faith that any outcome is related to one's own efforts. Self-efficacy is a collection of personal strong belief that one individual can achieve his or her own goals. In this study, if a person has a tendency to adopt an internal locus of control, meta-cognition is improved, and self-efficacy can in turn be increased if meta-cognition is improved. This study conducted an empirical analysis through questionnaires conducted on 260 university students. The results of the research demonstrated that there is a highly positive correlation between metacognition, control position, and self-efficacy. In addition, this study emphasized that positive meta-cognition with internal locus of control can lead to positive attitudes and behaviors, and positive results.
