  • This paper inquires the elements of emotional design and the current conditions of its application in order to examine the particularities arise when planning emotional interior design for a women's clinic. Research was done by studying plans for elements of emotional interior design while site investigation was done to find out the status of women's clinic lobby. Six women's clinic in Ulsan were chosen as subjects while survey was done based on the studied emotional plan elements. The data evaluation was classified by the installed properties and substituted with image scale using emotional mensuration. The outcome is as follows; First, elements of emotional interior design was composed of elements making up the space's comfort and aesthetic appreciation, and elements stimulating human's five senses leading to psychological treatment. Therefore, the plan for interior design should merge the design elements that stimulate senses and social elements into one unified concept. Second, the composited elements within the plan should strive to stimulate sights by contracts and changes and add symbolic or meaningful elements based on the principles of design. In so doing, the plan should incorporate an aesthetic orderliness and a coherent image. Third, the interior of women's clinics should not only have psychological comfort but also liveliness and ease that suits 20-30 old women. To conclude, Color, form, finishing materials and texture should be selected with a unified style in mind and the plan itself should strive to generate playfulness though harmonious coordination.

  • 터널과 매우 인접해 폭발이 일어날 경우 터널의 기능을 회복하기 위해서는 발생된 버력을 신속히 외부로 처리하여야 한다. 본 연구에서는 폭발에 의해 발생된 버력량을 파악하여, 터널 외부로 처리하는 데 걸리는 시간을 예측하는 방법론을 제시하고자 하였다. 이를 위해 SolidWorks를 이용하여 3차원 요소망을 작성하고, AUTODYN을 이용하여 폭발해석을 수행하였다. 터널과 해석결과로부터 얻어지는 파쇄영역과의 관계에 근거하여 유입되는 버력량을 이론적으로 산정하는 방법을 제시하였다. 또한 건설장비의 선정에 따라 버력을 처리하는 데 걸리는 시간을 예측하고 결과들을 비교 분석하였다. 연구 결과, 터널 내부로 유입되는 버력량은 터널과 파쇄영역의 관계를 4가지로 분류하고, 구분구적법을 이용하여 효과적으로 산정될 수 있음을 확인하였다. 또한 폭발위치가 터널 갱구와 굴착면에 가까울수록, 또한 중심선으로부터 벗어날수록 버력량이 감소해 처리시간이 줄어드는 것을 확인하였다.

  • The fundamental theorem of calculus is the most 'fundamental' content in teaching calculus. Since the aim of teaching the theorem goes beyond simple application of it, it is difficult to teach it meaningfully. Hence, for the meaningful teaching of the fundamental theorem of calculus, this article seeks to find the educational implication of the fundamental theorem of calculus through reviewing the genetic history of it. A genetic history of the fundamental theorem of calculus can be divided into the following five phases: 1. The deductive discovery of the fundamental theorem of calculus 2. Galileo's Law of falling body and the idea of the fundamental theorem of calculus 3. The discovery of the fundamental theorem of calculus and Barrow's proof 4. Newton's mensuration 5. the development of calculus in 19th century and the fundamental theorem of calculus The developmental phases of the fundamental theorem of calculus discussed above provides the three educational implications. first, we can rediscover this theorem through deductive methods and get the ideas of it in relation to kinetic problems. Second, the developmental phases of the fundamental theorem of calculus shows that the value of this theorem lies in the harmony of its theoretical beauty and practicality. Third, Newton's dynamic image of this theorem can be a typical way of understanding the theorem. We have different aims of teaching the fundamental theorem of calculus, according to which the teaching methods can be adopted. But it is self-evident that the simple application of the theorem is just a part of teaching the fundamental theorem of calculus. Hence we must try to put the educational implications reviewed above into practice.

  • Without annual ring, the bamboo can not measured by ordinary mensuration method. Other methods yet tried failed to prove the reliability. That means, as often pointed out, that the bamboo lumbering (including forest management) is not free from being precarious. Noting the fact, this author performed a serieds of comparative observations on a group of bamboos in different stages of growth in order to find out if there is any surer mensurability. A conclusion has been reached that the external feature of joints of branch has close connection with the age of bamboo, that the joints of the third major branch counting from the ground have, as shown in the first table, the most probability, its mean being 94.3 per cent, and that those in ages of 3 to 5 have the probability of 100 per cent, showing the far greater accuracy as compared with those in older ages. The above conclusion needs to be adjusted with the following findings; 1) When observed disregarding the joint-tongue(the remainder of the preceeding year's sheath), the major branches show no better probability than the minor ones. 54 to 78 per cent of them shows no difference between them. Probability is averaged by 60 per cent. 2) When in spring the old sheaths drop away from the joints, the new ones sprout out in their places and consequently the joints present an appearance of a kind of joint-ring. But since this joint-ring does not always exactly represent the plant age, some other method must be sought after to count the age. This author noticed what is called "joint-tongue" the tongue-like part of triangle shape which remains at the base of the sheath of the fallen leaf. A fact was ascertained that when the number of the joint-ring coincides with that of the remaining joint-tongue, it exactly indicates the age of the plant.the plant.

  • Dryland species and ecosystems have developed unique strategies to cope with low and sporadic rainfall. They are highly resilient and recover quickly from prevailing disturbances such as fires, herbivore pressure and drought. Dryland people have engineered pastoral and farming systems, which are adapted to these conditions and have sustained the livelihoods of dryland people for centuries. In this article, we present the status of potentials and threats to dryland biodiversity and explore options for its conservation and sustainable use. Findings of the research can be summarized as follows: (i) The ecosystem goods and services are highly valued by the community but mechanism for wise use of the resources has disappeared, (ii) forests are under the ownership of the government but the local community is the realistic custodian of the forests through village leaderships and environmental committees; (iii) the immediate major threat to dryland biodiversity held in the forests appears to be the degradation of ecosystems and habitats caused by new and powerful forces of environmental degradation such as large scale irrigation of rice farms, poverty-induced overexploitation of natural resources, and disappearance and ignorance of traditional institutions for management of dryland biodiversity. These new forms of disturbances often overpower the legendary resilience of dryland ecosystems and constitute potentially serious threats to dryland biodiversity. Forests, wetlands and oases all of which are micro hot spots of dryland biodiversity, appear to be particularly vulnerable hence the need to set up some rules and regulations for sustainable utilization of these resources.

  • The seismic safety of nuclear power plants has always been emphasized by the effects of accidents. In general, the seismic safety evaluation of nuclear power plants carries out a seismic probabilistic safety assessment. The current probabilistic safety assessment assumes that damage to the structure, system, and components (SSCs) occurs independently to each other or perfect dependently to each other. In case of earthquake events, the failure event occurs with the correlation due to the correlation between the seismic response of the SSCs and the seismic performance of the SSCs. In this study, the EEMS (External Event Mensuration System) code is developed which can perform the seismic probabilistic safety assessment considering correlation. The developed code is verified by comparing with the multiplier n, which is for calculating the joint probability of failure, which is proposed by Mankamo. It is analyzed the changes in seismic fragility curves and seismic risks with correlation. As a result, it was confirmed that the seismic fragility curves and seismic risk change according to the failure correlation coefficient. This means that it is important to select an appropriate failure correlation coefficient in order to perform a seismic probabilistic safety assessment. And also, it was confirmed that carrying out the seismic probabilistic safety assessment in consideration of the seismic correlation provides more realistic results, rather than providing conservative or non-conservative results comparing with that damage to the SSCs occurs independently.

  • 알코올 급여 흰쥐에서 알코올성 간독성에 대한 누에배설물(silkworm excrement powder)의 영향을 검토하기 위하여 반합성 식이에 누에배설물을 3% (w/w) 수준으로 첨가하여 30일간 급여한 후 혈중 알코올 및 지질 농도, 간 기능 지표 효소 활성 및 간 조직 검사를 실시하였다. 임상생화학적으로 중요한 간 기능 지표 효소인 alanine aminotransferase (ALT), aspartate aminotransferase (AST), $\gamma$-glutamyl transpeptidase ($\gamma$-GTP) 및 lactate dehydrogenase (LDH) 활성이 알코올 대조군에서 증가하였다. 또한 혈중 알코올 농도도 알코올 섭취에 의해 증가하였다. 그러나 누에배설물 투여에 의해 혈중 ALT 및 LDH 활성은 현저하게 감소하였다. 혈중 중성지질, 콜레스테롤 농도는 알코올 대조군에 비해 누에배설물 투여에 의해 현저히 감소하였다. 또한 간 조직 검사에서 알코올 대조군에서 많은 지방적이 나타나 지방간이 확인되었으나 누에배설물 투여에 의해서는 지방적의 크기와 수가 많이 줄어드는 결과를 얻었다. 이상의 결과에서 누에배설물에 의한 알코올-유발 간독성의 개선효과는 간 조직의 임상생화학적 지표 효소의 활성 감소에 기인하는 것으로 나타났다.
