In this study, an seismic isolation system is suggested using a Natural Rubber Bearing(NRB) on a stainless steel water tank for stability assurance in an earthquake. A shaking table test was carried out to evaluate the seismic capacity of a non-isolated water tank and an isolated water tank. Displacement meters in the water tank measured the behavior characteristics of the tanks, which were compared using artificial seismic waves of 0.154g, 0.231g, 0.341g and 0.348g with water levels of 0.0m, 1.5m and 2.5m. At 2.5m, a decrement effect was generally shown in the isolated water tank, and a bigger displacement occurred in the non-isolated water tank than in the isolated one at water levels of 0.0m and 1.5m. It is interpreted that the weight of different water levels affects the decrement effect. If seismic reinforcement is done, the isolated bearing should be designed while considering the fluid storage level.

일반논문 : 石顚(석전) 鼎鎬(정호)의 국토 기행시

김석태 ( Seok Tae Kim ) 한국고시가문화학회(구 한국고시가문학회) 2015 한국시가문화연구 Vol.0 No.36

이 논문은 근대의 불교사상가이자, 교육가, 문학가인 石顚 鼎鎬의 기행시 에 대한 고찰이다. 석전은 우리나라 거의 모든 지방을 두루 여행 하였다. 그여행의 견문과 감회를 다수의 시문으로 남겨 인간의 삶과 여행, 그리고 문학이 한데 어우러진 다양한 기행시문학을 조성하였다. 그의 시작품의 대부분이 기행시라고 해도 과언이 아닐 정도인데, 여기에서는 제주도, 금강산, 백두산 기행시를 중심으로 석전의 국토 기행시의 내용과 의의를 살펴보았다. 제주 기행시는 선경의 이미지를, 금강산은 불교적 분위기를, 백두산은 웅혼한 기상을 느끼게 한다. 각 지역의 산수자연과 지나온 역사의 감회에 따라 시의 양상도 다른 것이다. 석전의 기행시는 여행 목적지에서의 감상 뿐만아니라 출발에서 돌아오기 까지 여행의 과정을 시로 표현하고 날짜, 동행한 사람 등 시작의 배경이 되는 상황을 적절하게 기록하여 여정을 알게 하였다. 이렇게 시문 자체가 맥락이 있는 여행기로 느껴지게 한 것은 석전의 기행시의 한 특징이라고 할 수 있다. 석전은 우리 땅 곳곳의 역사와 사람들의 삶, 자연을 애정 어린 시선으로 바라 보았으며 그 감회를 시인이자 수행승의 감성과 시각을 통하여 시로 형상화 하였다. This research is a consideration on the travel poetry of Seokjeon Jeongho(石顚 鼎鎬), a modern Buddhism thinker, educator, and writer. Travel poetry is to write experience of travel in poem. In literature, travel was an important deed to broaden deep insight and discernment through growing spirit and various experience by touring the broad world. Also, it was a road of pilgrimage to trace the history of the land and human life by being absorbed in beautiful nature. Seokjeon prepared a wide view of Buddhism as well as Confucianism, veteran science, and literature. He left high-level criticism on the literature, and created lots of poems and proses. Seokjeon, who prepared wide knowledge and literary competence widely traveled almost all regions of Korea. He composed various travel poetry literature combined with human life, travel, and literature by leaving the experience and inspiration on the travel with several poems. Most of his poem works were travel poetry, this research investigated the content and significance of travel poetry of Seokjeon mainly with Jeju island, Geumgang mountain, and Baekdusan travel poetry. Jeju, Geumgang mountain, and Baekdusan are very beautiful and historically significant places, located in the south, east, and north of Korea respectively. Jeju travel poetry implies the image of Seonkyung, Geumgang mountain implies Buddhistic atmosphere, and Baekdusan implies grand spirit. Poetic aspect differs along with landscape of each region and the historical emotion. Travel poetry of Seokjeon expressed the process of travel from start to return including impression in the travel destination with poem and properly recorded the situation of the background of poem creation such as date, fellow traveler, etc. This way, the point that poetic phrase itself is felt like a travel site with context is a characteristic of travel poetry of Seokjeon. Seokjeon viewed the history of each place of our land, people``s life, and the nature with an affectionate sight, and embodied that impression in poem through the sensitivity and sight of a poet as well as a Buddhist monk.

본 연구는 엘크 사슴고기(Elk deer, Cervus elaphus andadensis)에서 생산된 등심(T1)과 뒷다리 부위(T2)에 대한 품질특성을 파악코자 실시되었으며, 분석 결과는 다음과 같다. T2가 T1보다 수분 함량은 낮고, 단백질 함량은 높았으며, 전단가는 낮고 보수력은 높았다. 육색 측정 결과 T1 및 T2 간 명도, 적색도, 황색도 모두 유의적인 차이가 없었다. 조직 특성 조사에서 경도, 부착성, 검성 및 파쇄성은 유의적인 차이가 있었으나, 응집성과 탄력성은 유의적인 차이가 없었다. 지방산 조성은 T2가 myristic acid와 linoleic acid의 함량이 각각 5.06와 10.37%로 T1이 유의적으로 높았으며(p<0.05), palmitoleic acid는 그 반대였다. SFA와 UFA는 두 부위 간 유의적인 차이가 없었으나 EFA는 T1이 유의적으로 높았다. 전체적인 기호도는 유의적인 차이 없이 신선육에서 T2가 다소 높았고, 가열육에서는 오히려 다소 낮게 나타났다. This study was carried out to evaluate the quality characteristics on the two different muscles (Loin; T1, Ham; T2) from the Cervus elaphus andadensis (Elk deer). The water content and shear force of T1 were lower than that of T2. The protein content and water holding capacity were lower in T2 compared to the T1. In meat color, $L^*,\;a^*\;and\;b^*$ values were not different between T1 and T2. In the texture properties, there were significantly (p<0.05) differences in hardness, adhesiveness, gumminess and brittleness, but cohesiveness and springiness were not different significantly (p<0.05). In fatty acid analysis, myristic acid and linoleic acid of T2 were high (p<0.05) as 5.06 and 10.37% respectively, while palmitoleic acid of T1 were significantly (p<0.05) higher than that of T2. SFA and UFA were not different between the T1 and T2, although EFA of T1 was significantly (p<0.05) higher than that of T2. In sensory evaluation, acceptability of T2 in fresh meat showed the slightly high, but that of T2 in cooked meat was slightly low score. All samples were not significantly different in overall acceptability.

지도학습의 효율성을 위한 입체지형 제작 방법

김석태 ( Seok Tae Kim ),조성욱 ( Sung Wook Cho ) 한국지리환경교육학회 2014 한국지리환경교육학회지 Vol.22 No.2

지도학습은 방위학습, 기호학습, 위치학습, 축척학습 그리고 등고선 학습으로 구성된다. 이 중 등고선 학습은 지형의 기복을 약속된 규칙에 의해서 표현하고 이것을 다시 해석하는 학습영역이기 때문에, 단순히 이해에 머물지 않고 학습자의 공간능력을 요구하고 있다. 등고선 학습을 통하여 학습자는 지도로 표현된 2차원의 세계를 3차원의 세계로 다시 전환할 수 있는 능력을 키울 수 있으며, 이러한 능력의 개발을 통하여 기호로 표현된 도구(자료)의 공간적 시각화가 가능하고, 시각화된 공간의 오리엔테이션(방향전환)과 공간적 관계 파악이 가능하여, 기존에 잠재해 있던 공간 능력을 활성화 시킬 수 있는 계기를 마련하게 된다. 즉, 등고선 학습을 통하여 2차원의 세계를 3차원의 세계로 인식하는 과정은 학습자의 공간능력을 자극한다는 측면에서 중요한 교육적 의미를 지닌다. 본 연구에서는 그동안 등고선 학습에 도입되었던 다양한 방법들의 한계점을 보완하여, 지형도 2장과 2장의 판지를 이용한 입체지형 제작 방법을 제안했다. 한쪽 판은 홀수 등고선만 자르고, 또 다른 한쪽 판은 짝수 등고선만 잘라서 상호 교차하여 붙이는 방법이다(교차식 방법). 이 방법은 학습자들이 간단한 과정을 통하여 직접 제작할 수 있고, 등고선 위에 붙이기 때문에 등고선의 속성을 정확하게 이해할 수 있으며, 작업과정이 비교적 단순하여 1~2시간의 모둠별 수업 공간에서 해결이 가능하고, 재료가 적게 들어 비용부담이 적으며, 간단한 설명으로도 바로 작업에 임할 수 있다는 장점이 있다. Map learning is consists of the direction learning, the symbol learning, the location learning, the scale learning, and the contour learning. Especially, the contour learning has demanded the learners` spatial ability because it simply does not remain in the understanding about the relief of the terrain represented by the rules, but need to re-interpretation. Through the contour learning, the learner cultivate transform ability from the world of the two-dimensional to the three-dimensional. And it activate the spatial ability in existing opportunity that they have the potential to identify the spatial relationships. Eventually recognized as a three-dimensional world from the two-dimensional through contour learning process is simply does not remain in the understanding of the contours in the sense that stimulate the learners` spatial ability. That is an important educational significance. In this study, propose new method to make three-dimensional terrain, it compensate for the limitations of the various methods had been introduced in the learning contour, this new method(crossing method) is only using topographic maps 2 unit and cardboard 2 pieces. The attached to the cross-cut after one side is only cut the odd number and the other side cut the even number. It has advantage that the process is relatively simple and takes a little time and materials and space for working, only need a brief description for operation, and can be represented exactly according to contours. This new method has advantage in each learners to create their own terrain by themselves, can be solved within one or two hour of class time and can work normal classroom space of group learning, high accuracy, and low cost.
