A malignant peripheral nerve sheath tumor (MPNST) is a rare soft tissue tumor defined as any malignant tumor arising from or differentiating toward the cells of the peripheral nerve sheath. It is one of the malignant tumors associated with neurofibromatosis type 1 (von Recklinghausen`s disease). They occur most commonly on the lower and upper extremities, trunk, head, and neck, while intrathoracic tumors are very rare. We report an intrathoracic MPNST in a 66-year-old female with neurofibromatosis type 1. (Korean J Med 76:234-237, 2009)

최진이(Choi, Jiny)(崔辰而),문유미(Moon, You-Mi)(文有美) 대한중국학회 2020 중국학 Vol.71 No.-

본 논문은 초·중급 학습자를 위한 교재코퍼스 개발을 통해 난이도 별로 예문을 적절하게 활용하는 방안을 제시하고자 한다. 초·중급 교재코퍼스 개발은 학습자들이 배우고자 하는 어휘나 문법 규칙에 다양한 방식으로 노출될 수 있도록 예문을 수집하고 학습의 주체가 되어 활용할 수 있다는 점에서 큰 장점이 있다. 이에 본고는 회화, 문법, 작문 등의 연계교육에 교재 코퍼스가 어떻게 활용 가능한지 다양한 형태의 수업 방안을 제언한다. This paper tries to suggest the way of properly using different types of example sentences by the difficulty levels to teach a foreign language, through the development of pedagogic corpus for low-intermediate learners. A pedagogic corpus enables instructors and learners to set up their own learning goals and can collect and create their desired corpus materials. For this, the development of pedagogic corpus tried to focus on collecting different example sentences from a wide range of materials and subdivide types of materials and units or categories containing example sentences in order to allow learners to be exposed to vocabularies or grammar rules they want to learn in various contexts. Besides, different types of proposal of lesson plans using a pedagogic corpus have been made, in that conversation, grammar, and writing are integrated in a single lesson. By pursuing further research mentioned below, this paper will contribute to enhanced educational and academic effectiveness of the pedagogic corpus being currently developed. First, characteristics of example sentences in teaching materials published in Korea will be analyzed to find differences from the educational corpus used in China. Second, it will try to find a way to use the analysis of parts of speech and elements of sentence in each example sentence. The part-of-speech tagging facilitates the easy analysis of method of using words to make a sentence and the sentence structure. The grammar structure analyzed in this way can be the basic data for teaching and learning conversation, writing, and translation.

딥 러닝 훈련 시간 개선을 위한 쓰레드 기반 셔플링 기법

최진서(Jinseo Choi),강동현(Donghyun Kang) 한국정보과학회 2022 정보과학회 컴퓨팅의 실제 논문지 Vol.28 No.2

딥 러닝(Deep Learning)이 기존의 문제 해결에 새로운 방향을 제시함으로써, 다양한 환경에서 딥 러닝을 적용하고 있다. 이에 따라, 딥 러닝 프레임워크도 점차 발전하고 있는 추세이다. 그러나, 딥 러닝에서 대용량의 데이터를 학습하기 위해서 필요한 데이터 처리 과정은 여전히 개선의 여지를 남겨두고 있다. 이에, 본 논문에서는 딥 러닝의 학습 과정을 빠르게 진행하기 위한 새로운 데이터 처리 방법인 쓰레드 기반 셔플링 기법을 제안한다. 제안 기법은 멀티 쓰레드를 이용하여 딥 러닝 학습에 필요한 데이터를 임의의 순서로 재 정렬함으로써 CPU의 사용률을 향상시킨다. 실험을 통해 실험을 통해 우리는 제안 기법이 기존 기법 대비 셔플링 시간을 최대 50.7% 그리고 전체 훈련 시간을 최대 13.6% 감소시킬 수 있다는 사실을 확인하였다. 또한, 쓰레드 단위로 데이터를 분할함으로써 발생할 수 있는 정확도 문제를 확인함으로써, 제안 기법이 정확도에 영향을 미치지 않는다는 사실을 확인하였다. Deep learning is being applied to various environments as it is working towards a new direction that solves many traditional problems. Therefore, there is a trend that the deep learning framework is gradually developing. However, the data processing process to learn the amount of large data in deep learning has still left room for optimization. In this paper, we propose a thread-based shuffling scheme to speed up the learning process of deep learning. The proposed scheme enhances CPU utilization by ordering data in a random way with multi-threads. Through evaluation, we confirmed that our scheme can reduce the shuffling time by up to 50.7% as well as the total training time by up to 13.6% compared to the conventional approach. Additionally, we also validated the fact that the proposed scheme has no effect on the accuracy issue caused by splitting a range of data into each thread.

The double derivative suit is action by the shareholders of parent company. As it were, The shareholders of parent company bring a lawsuit on behalf of parent companies or shareholders of subsidiary against subsidiary's directors. even though the shareholders of parent company aren't possessed of subsidiary's stocks. In August 22, 2003, The High Court Seoul(an appellate court) gave a judgment on standing in shareholder derivative action. The Court found for the plaintiff who are the shareholder of parent company. This decision is the first winning case of the double derivative suit. But, In September 23, 2004, The Supreme Court dismissed the action and overturned a low court's verdict(High Court Seoul decision, in August 22, 2003). Taking this opportunity, the double derivative suit is being in a controversy in earnest whether permission the double derivative suit or not. This paper suggested how to permission of the double derivative suit and the necessity of legislation. The double derivative suit is very important to remedy of shareholder. But, most of executives and some scholars are worried that the government will introduce the double derivative suit. Also Even some of who agree with introduction of this suit don't agree to codify the prerequisites of this suit, because this suit is extraordinary and exceptional device to help the shareholders of parent company. This paper's contention is introduction of double derivative suit, and suggested legislation the method of the introduction the suit system. The double derivative suit can makes compensation for consequential damage of the parent company's shareholders, and also can makes compensation for parent company's consequential damage. As a result, recovery indirectly benefit both of parent company's shareholders and parent company.

도덕적 어지럼증과 윤리적 반성의 상관관계 고찰

최진일(Choi, Jin Il) 광주가톨릭대학교 신학연구소 2015 神學展望 Vol.- No.190

과학기술의 발전은 인간에게 많은 혜택을 주며, 미래에 대한 긍정적인 전망을 가능케 한다. 한편 과학기술이 인간 생명의 초기 단계에 개입되면서 많은 우려를 낳고 있는 것도 사실이다. 인간 배아의 헌법상의 지위로 보았을 때, 배아에 대한 과학기술의 개입이 배아의 기본권을 침해하지 않는 듯 보인다. 그럼에도 불구하고 우리는 과학기술에 의해 파괴되어 나가는 배아를 볼 때, 무언가 잘못되고 있는 것은 아닌지 의문을 품게 된다. 인간 배아는 그냥 하나의 세포덩어리에 불과한 과학재료가 아니라 누군가의 자녀이자, 인간의 고귀한 생명의 시작 단계이다. 법적인 테두리에서 배아에게 주어진 지위가 배아의 도덕적 그리고 인간학적 지위를 대변하지는 않는다. 사회적으로 승인된 행위를 무조건적으로 따를 것이 아니라 우리는 먼저 그 승인의 이유와 함께, 그 근거가 정당한지를 물어야 한다. 그렇지 않게 되면, 우리는 무언가 잘못되어 있다고 의문을 제기하면서도 무엇이 잘못되어 있는지를 논의하는데 한계에 부딪힐 것이며, 결국 문제 해결책을 찾는데도 어려움을 겪을 것이다. 그러한 과정에서 우리가 경험하게 되는 것이 도덕적 어지럼증이다. 따라서 이것을 극복하기 위해서는 의문이 제기된 표면적인 차원뿐만 아니라 그 의문과 관련된 가치체계의 근거에 대한 윤리적 반성이 필요하다. 이를 통해 인간 생명과 관련된 생명윤리 문제의 본질에 접근할 수 있을 것이다. 문제 해결의 근본적인 토대는 경험적 사실만이 아니라 그 너머에 있는 인간 본성을 파악할 때 확립할 수 있다. 그런 다음에야, 우리는 인간 생명의 존엄성, 그 존재 이유와 행위의 진리를 알아낼 수 있으며, 인간 인격의 존엄성에 부합한 행위가 무엇인지를 판단할 수 있다. The development of scientific technologies offers many benefits to humankind, thus showing us a blueprint of the future. It is true that some of these technologies intervene at the beginning of human life, bringing a considerable amount of concern. According to the constitutional status of the human embryo, technological intervention of the human embryo does not seem to violate any fundamental rights of the embryo. Nevertheless, we often call into question that something, indeed, is going wrong when we observe that human embryos are destroyed by these scientific technologies. The human embryo is not just a cell mass to use scientific research, but a child of someone, and is in the early stages of human life. This tells us that an individual human life has already begun. The status of human embryos defined in legal terms does not represent the moral and anthropological status of the human embryo. Therefore, before accepting any behavior or action that is considered socially recognized, we must first ask the reason for the justification of such a behavior or action. Otherwise, we come to the end of our tether to define what is going wrong, although continually raising the question that something, indeed, is wrong. Eventually, we have difficulties finding a way out of the problem. What we experience in such a process is called moral vertigo. To overcome this vertigo ethical reflection is required not only on the apparent aspects of the problem, but also on the foundation of the value system related to it. Thus, we are able to reach the heart of the problem in bioethics relevant to human life. Solving the problem requires grasping a deep understanding of human nature that goes well beyond empirical facts. Then, we will be able to identify the dignity of human life, the reason for being, and the truth of behaviors. We will be capable of judging what actions will be in conformity to the dignity of the human person.

화물자동차운송은 항공·해상·철도운송 등 다른 운송수단에 비하여 중단거리 운송에 적합하며 무엇보다 문전수송이 가능하기 때문에 국내 육상화물의 약80%가 이에 의존하고 있음에도 불구하고, 국내 화물운송시장은 열악한 사업환경 뿐만 아니라, 화물운송거래구조에 심각한 문제점을 안고 있다. 이는 화물운송산업의 경쟁력을 약화시키는 것은 물론, 화물운송시장의 성장을 저해하는 요인으로 작용하고 있다. 이에 정부는 화물운송시장에서의 다단계 운송거래구조를 개선하기 위해 「화물자동차운수사업법」을 개정(2011.6.15) 하였다. 주요 개정내용은 화물운송사업자의 직접운송의무와 직접운송의무 비율, 위탁화물관리책임, 화물운송실적신고제, 화물운송사업자 및 운송주선인의 재위탁 제한 등을 담고 있는데, 이들 개정내용들의 시장효과여부는 가까운 장래에 나타날 것이다. 이 논문에서는 개정법의 핵심쟁점사항들 중에서 화물운송사업자에게 가장 직접적인 영향을 미치고 있는 화물운송사업자의 직접운송의무 및 직접운송비율제도의 취지와 이 제도가 갖는 문제점을 분석하고, 화물자동차관리회사제, 예외 축소 등과 같은 다단계 화물운송거래구조 해소를 위한 몇몇의 개선방안을 제시하였다. Domestic truck transport market doesn’t have only the poor business environment but also the serious defects on the transportation structure. It makes weaken the competitiveness of truck transport industry and hinders growth of truck transport industry. As a result, on June 15, 2011, the Government amended the TRUCK TRANSPORTATION BUSINESS ACT(Enforcement Date 1. January, 2013, Act No. 10804, 15. June, 2011) to improve the abnormal multi-level transportation structure. The main issues of the revision are the direct transportation duty of truck transportation business operator, the direct transportation duty rate of truck transportation business operator, the prohibition of the extended contracts and re-mediation agency of the motor freight transportation business operatior. The effective of these main contents of the amended Act will be clear in the near future. In this study, It is examined the issues and improvements to the direct transportation duty of truck transportation business operator and the direct transportation duty rate of truck transportation business operator among the main contents of the amended Act. These two contents of the amended Act have an ovject to improve the abnormal multi-level transportation structure. But the government need to remember that forcing the new rules are not best. If forcing the truck transportation business operator to amended strict rules can also have a few side effects. Therefore, this paper pointed out the controversial issues and also proposed several solutions like reduce of exceptions to the rule, truck management company to improve abnormal multi-level transportation structure in the truck transport market.

Purpose: This study investigated the factors influencing sleep quality in adults according to age groups. The escriptive study was conducted in metropolitan areas of South Korea to control for possible sleep differences between adults living in rural areas and those living in cities. Participants were 450 adults between 19 and 65 years old. Methods: Self-administered questionnaires consisting of including the Korean Modified Sleep Leeds Evaluation Questionnaire, the International Physical Activity Questionnaire and the Perceived Stress Scale were used to assess the quality of adults’ sleep. Results: Sleep quality was poor across the all age groups Stress and subjective health status were influencing factors of sleep quality among participants in their 20s; subjective health status and circadian rhythm (evening-type) were influencing factors of those in their 30s; subjective health status, alcohol consumption, and work days of less than 8 hours were influencing factors among participants in their 40s; and stress, circadian rhythm (evening-type), subjective health status, work days of over 11 hours, past smoking habit, and light physical activity were influencing factors of those aged 50 years and over. Conclusion: The quality of sleep was low across the all adult age groups in South Korea. Although the factors influencing quality of sleep differed by age groups, they in general indicate the need to focus on maintaining and controlling health status in sleep interventions.
