Air Pollution Reduction Strategies of World Major Ports

Han,Chul Hwan 한국무역상무학회 2010 貿易商務硏究 Vol.48 No.-

Pollution emissions from international shipping and port activities have a significant impact on public health and global climate changes. The purpose of this paper is to review the status of pollution mitigation measures implemented to date in port industry and find out some implications for Korean ports. For this aim, the clean air strategies of the world major ports including six USA ports (Los Angeles/Long Beach, Now York/New Jersey, and Seattle and Tacoma), two European ports (Rotterdam and Gothenburg) and Busan Port were considered. Various measures to reduce emission from ports are evaluated by sectors-ocean going vessels, cargo handling equipments, truck and rail-, on the basis of categories such as reduction control technologies, operational changes and market-based measures. The policy implications of this paper are as follows. First, Clean Air Act Plans of Korean ports are required as soon as possible. Second, integrated approach is required to reduce emission effectively. Finally, the effect of port-related emission reduction can be maximized when various measures are conducted on a regional basis including neighboring ports. Furthermore, regional or global-based approach is useful to guarantee the level playing field among ports.

정지용 시의 ‘나븨’와 죽음 의식

한상철(Han, Sang-chul) 한국비평문학회 2014 批評文學 Vol.- No.52

이 논문의 목적은 정지용 시의 ‘나븨’ 표상에 주목하여 그의 시에 나타난 죽음 의식의 특성을 고찰하려는 것이다. 9편에 이르는 지용의 ‘나븨’ 관련 시 중 다수가 1927년과 1941년에 집중적으로 발표되었다는 사실을 고려할 때, ‘나븨’ 표상의 활용은 시인의 의도와 직접적으로 연동되었을 가능성이 크기 때문이다. 이러한 맥락에 주목하여 이루어진 본론의 논지는 다음과 같다. 첫째, 지용 시 전반에 걸쳐 등장하는 ‘나븨’ 표상은 죽음과 관련된 시적화자의 정서를 반영한다. 전기와 후기를 불문하고, 대부분의 시에서 시적화자의 비극적 현실 인식과 죽음 의식이 직간접적으로 드러나고 있음을 확인할 수 있다. 따라서 지용 시의 ‘나븨’ 표상에 대한 가장 강력한 대응점은 신산스러운 삶의 고통과 그것을 벗어나는 행위로서의 ‘죽음’이라고 말할 수 있다. 둘째, 비교적 초기에 해당하는 1927년과 후기시의 특징이 전형적으로 드러난 1941년의 ‘나븨’ 표상에는 분명한 차이가 존재한다. 주로 자식의 죽음과 관련된 전자의 ‘나븨’ 표상이 슬픔과 애상의 정조를 바탕으로 한계 상황에 놓인 존재의 절박한 심경과 맞닿아 있다면, 1941년의 시에 보이는 ‘나븨’들은 죽음에 대한 비애 자체에 머물지 않고 외려 삶의 이면을 성찰하게 만드는 관조적 태도를 보여주고 있다. 셋째, 지용의 죽음 의식이 변모하는 중요한 분기점은 1930년대 중반에 발표된 카톨릭 종교시라고 말할 수 있다. 카톨리시즘에 대한 천착 과정을 거치며 현실의 삶과 초월적 삶의 경계에 선 시적 화자의 태도가 형성되었다고 보이기 때문이다. 이처럼 죽음의 비극과 그것으로부터의 초월이 동시적으로 공존하는 세계에 대한 체험은 후기 지용 시의 관조적 세계 인식을 만들어낸 중요한 계기가 된다. The purpose of this article is to bring light on the meaning of the death consciousness in Jiyong’s poetry by focusing on the representation of ‘Nabui(butterfly)’. Relating to the representation of ‘Nabui(butterfly)’, the death consciousness in Jiyong’s poetry has three characteristics mainly. First, the representation of ‘Nabui(butterfly)’ in his poems connotes a painful life and the meaning of the ‘death’ as the act of seeking relief from suffering. second, there are marked differences in the representation of ‘Nabui(butterfly)’ in Jiyong’s poems which were published in 1927 and 1941. The representation of ‘Nabui(butterfly)’ was based on sentiment of sadness and sorrow in his 1923 poem, while it showed a contemplative attitude to introspect the hidden side of life in his 1941 poem. Third, Jiyong published religious poetry influenced by Catholicism in the mid 1930s. This was a important turning point which the death consciousness of Jiyong was transfigured. In the process of digging into Catholicism, it is shown that the narrator’s attitude is formed from the boundaries between practical life and transcendental life.

단위제 실시에 관한 문제점 조사연구 : 제주도 인문계 고등학교를 중심으로 on the humane high schools in Jeju-Do

한철순,현종익 제주대학 1980 논문집 Vol.12 No.2

Our educational courses and curriculum have frequently due to frequent changes in the educational environment. In the highshools, the unit system was adopted on Feb, 15th, 1963. Yet the current school teachers have a poor understanding and knowledge of it. Therefore, this system can't be run effectively. The current school teachers undertake many difficulties by accepting responsibilities for school affairs. There is a pressing need to increase their knowledge of the unit system. The salient point of the unit system is that in principle every high school should adopt the unit system. Under our actual education circumstances, it is very hard to adopt the complete unit system. However, in order to promote uniform education and to have chance to take one's adoptability by opticonal course, we should have deep knowledge of it. The unit system prescribes as follows; 1) In principle, the high school teaching curriculum should adopt the unit system. However, due to difficulties adopting the unit system, they can adopt the grade system, or both the grade system and the unit system. 2) The unit allotment table shows the total unit numbers which the 3rd grade high school students need to complete the regular course. 3) Usually we have 36 weeks of school-days per year. One unit means to complete the regular course for 18 unit hours per term, and 1 unit hour has 50 minutes. 4) According to student's career and job selection, high school courses can be dclassified into humanistic, scientific, vocational and art courses. 5) with respect to the weather, season and the characteristic of the subject contents, they can make an available unit-hour education curriculum. But since most of the current school teachers have a poor knowledge on the principles of the unit system, the aim of this paper is to help them understand the necessity of the unit system and to offer them information necessary to restructure the education curriculum. In conclusion this paper describes the actual circumstances and problems of high schools, and attempts to improve them

본 연구는 컴퓨터 교과 내용학 지도를 위한 개념 학습 모형 설계에 관한 내용이다. 컴퓨터 교과 내용학의 추상적인 이론과 내용을 학습자가 이해 하기는 매우 어렵다. 또한 추상적인 컴퓨터 용어를 일반 교사가 안내하기 위한 교수 학습 전략 또는 모형이 없었다. 이러한 추상적 컴퓨터 개념과 용어를 교수 학습하기 위하여 본 연구에서는 개념 학습 모형의 구조와 개념 학습 모형에 대한 수업 설계 방법을 제안하였다. The purpose of this study is to design and to develop on the concept teaching and learning model for teaching the subject domains of the computer science. The student was so difficult to understand an abstract theory and terminology in the computer science. Moreover, it was out of existence the teaching and learning model to introduce that a teacher instructs the abstract theory and terminology in the computer science effectively. In order to support effective teaching and learning in the computer science, we proposed the new concept teaching and learning model for teaching the subject domains of the computer science.

Stewart 플랫폼을 이용한 손목 힘/토크센서의 해석

한정훈,강철구 건국대학교 1996 學術誌 Vol.40 No.2

A Stewart platform-based force/torque sensor with 6 instrumented elastic legs needs the solution of forward kinematics of the Stewart platform in order to obtain forces and torqueg acting on the upper plate from given 6 leg forces. The solution of forward kinematics, however, is not known in a closed-form. In this paper, the closed-form solution of forward kinematics is derived by means of the linearization of the solution of inverse kinematics, and the closed-form solution is used for the calculation of the force and the torque of the sensor. Kinematic design parameters of the Stewart platform are determined so that the force/torque sensor may have the isotropic force/torque properties and be installed in a robot wrist. The validity of the proposed linearization method is investigated through the calculation of forces and torques.

Environment Friendly architecture, which will reduce shortcomings of current architectural culture, can be achieved by using natural energy and environment friendly building materials together with their environmental architecture techniques. Particularly, even though the overall building system is perfect, it cannot be considered as comfortable architectural space if the materials are polluted, harmful to human bodies and producing wastes. Therefore, in order to build environment friendly architecture, the selection of the materials is very important and necessary from the planning stage with careful reviews and concern. This study tries to define what the environment friendly materials are, to investigate and to classify them, in order to provide some guidelines for selecting them at plans to build. For example, the materials can be classified into natural materials, continuously usable materials, recycled materials from wastes, and less polluting materials mixed with natural matters. Finally, this study reviews the existing products in the market and proposes to develop new ones in the future. It will present the circulation of resources in the 21 century throuth recycled and reused materials.
