최근 정보디자인 영역에서 애니메이션을 포함한 멀티미디어 활용이 급증하고 디자인 현장에서 응용이 확대되고 있음에도 불구하고 관련 연구는 매우 부족하며, 특히 어떤 특성이 정보전달효과를 향상시키는지에 대한 연구는 많지 않다. 지금까지 디자이너들의 관심은 독창성, 다양성 등 화면의 시각적 완성도에 집중되어 있었으며, 실제로 디자인에서 인지적 문제는 간과되어 왔다. 그러나 정보디자인의 궁극적 목적이 정보의 정확한 전달에 있다는 점을 생각한다면 독창성이나 다양성 이전에 정보 사용자의 혼란을 줄이고 정보전달력을 향상시키기 위한 인간의 시각적 인지능력, 기억력 등에 근거한 연구가 선행되어야 하고 이를 디자인에 적용하는 노력이 필요하다하겠다. 따라서 본 연구는 정보디자인에서 멀티미디어가 사용자인지 및 커뮤니케이션에 어떤 영향을 미치는지를 매체의 효용성 이론에 근거하여 검토하고 어떠한 환경 하에서 효과가 극대화될 수 있는지 살펴보고자 하였다. 매체의 효용성에 관한 이론들을 정리해 보면 멀티미디어와 같은 발달된 정보기술은 매체의 내재된 풍요도로 인하여 정보전달에 효과적으로 작용할 것이나 멀티미디어의 효과는 전적으로 매체풍요도의 관점에서 단순화시키기보다는 과제와의 적절성이나 인지적 적절성의 관점에서 다각적으로 분석해야 한다. 최적의 인터페이스 디자인을 위해서는 불필요한 인지부하를 없애면서 제한된 양의 작동기억을 최대한 활용하여 지식을 습득할 수 있도록 정보를 구조화하는 것이 중요하며, 또한 정확하고 성공적인 심상구축이 가능하도록 정보특성에 맞는 적절한 미디어 선택과 표현방법의 제시가 필요하다 할 것이다. 본 연구는 정보디자인의 커뮤니케이션 효과를 높이기 위하여 어떤 정보기술을 활용해야 하는가에 대한 의문을 매체의 효용성에 관한 이론들을 근거로 살펴봄으로서 향후 디자이너의 의사결정에 있어서 도움을 주고자 하였다.

Ground fissures have a huge effect on the integrity of surface structures. In high-intensity ground fissure regions, however, land resource would be wasted and city building and economic development would be limited if the area avoiding principle was used. In view of this challenge, to reveal the seismic response and seismic failure characteristics of ground fissure sites, a shaking table test on model soil based on a 1:15 scale experiment was carried out. In the test, the spatial distribution characteristics of acceleration response and Arias intensity were obtained for a site exposed to earthquakes with different characteristics. Furthermore, the failure characteristics and damage evolution of the model soil were analyzed. The test results indicated that, with the increase in the earthquake acceleration magnitude, the crack width of the ground fissure enlarged from 0 to 5 mm. The soil of the hanging wall was characterized by earlier cracking and a higher abundance of secondary fissures at 45°. Under strong earthquakes, the model soil, especially the soil near the ground fissure, was severely damaged and exhibited reduced stiffness. As a result, its natural frequency also decreased from 11.41 Hz to 8.05 Hz, whereas the damping ratio increased from 4.8% to 9.1%. Due to the existence of ground fissure, the acceleration was amplified to nearly 0.476 m/s², as high as 2.38 times of the input acceleration magnitude. The maximum of acceleration and Arias intensity appeared at the fissure zone, which decreased from the main fissure toward both sides, showing hanging wall effects. The seismic intensity, duration and frequency spectrum all had certain effects on the seismic response of the ground fissure site, but their influence degrees were different. The seismic response of the site induced by the seismic wave that had richer low-frequency components and longer duration was larger. The discrepancies of seismic response between the hanging wall and the footwall declined obviously when the magnitude of the earthquake acceleration increased. The research results will be propitious to enhancing the utilizing ratio of the limited landing resource, alleviation of property damages and casualties, and provide a good engineering application foreground.

Cooking food is very important in Chinese medicine when we regard the food to be the principal origin of the nutrition of human body and the condition required to maitain the activities of the life of human body. Chinese medicine has accumulated the diverse and rich experience of cooking food through long clinical experience as well as made an important contribution to the healthy and long life through the unique theory of cooking food. Chineses medicine has deep view on the relations between food cooking and healthy and long life as well as presented the principle of cooking food created unique ways of food cooking such as food treatment. As the above, from the ancient times, Chinese medicine established Chinese medical science of nutrition under the consciousness of the theory that food and medicine have the same origin and practiced the methods of promoting the health through rightly selecting the foods. Therefore it has been thought that human beings can enjoy healthy life by rich supply of the nutrition. Comfortable ways of sleeping requie the emotion and peace with temperation in pleasure and anger, and also we should be temporate in eating, acting, sleeping posture and be flee from the wind, and we should not put on a quilt when sleep, and we should sleep alone and be careful about sexual life. The concrete measures for sexual intercourse are that: 1) we should marry at the right age not to be married at early age. 2) we should obey nature and not live unmarried life. 3) we should be temperate in having sexual intercoure and in excessive sexual desire. Regarding the residence and clothes: the residence environment should be calm and beautiful and the room for the residence should be well designed to be clean and sanitary and we should wear suitable clothes. All living creatures are living according to the rhythm of the living body and the change of the great nature. The Reason why the living things show the periodical rhythm is not that it is the truth of the great nature, but that the living life itself shall be ceased to be existed in case of running counter to such rhythm. There are 2 specially important things: one is about food in biological view and the other is the residence in social side. By starting from the theory that food and medicine have the same origin and root, we should rightly select the foods to promote the health at the maximum, and it is very important for human to be well obeying the environment and temperate in the life of residence and mind (Choi, Sam Byun, Shon, Sook Young, 1997). As the above, the cook in Chinese medicine suggests us the suitable ways of achieving the goal of nursing. Therefore the continuous study of this field is necessary based on this my study though it is unsatisfactory at this time but it would be the basic materals in establishing the nursing science of Chinese medicine.

Paralytic shellfish toxins (PSTs) and tetrodotoxin (TTX) are neurotoxins that display pharmacological activity that is similar to that of specific sodium channel blockers; they are the principle toxins involved in shellfish and puffer fish poisoning. In Korea, puffer fish is a very popular seafood, and several cases of accidental poisoning by TTX have been reported. Therefore, it is necessary to determine whether puffer fish poisoning incidents are caused by PSTs or by TTX. In this study, we used mouse bioassay (MBA) and liquid chromatograph-tandem mass spectrometry (LC-MS/MS) to determine the presence of PSTs and TTX in puffer fish from an area near Mireuk-do, Tong-Yeong on the southern coast of Korea from January through March, 2014. The toxicity of PSTs and TTX extracts prepared from three organs of each specimen was analyzed by MBA. Most of the extracts killed mice with typical signs of TTX and PSTs. The LC-MS/MS analysis of seven specimens of Takifugu pardalis and Takifugu niphobles, each divided into muscles, intestines, and liver, were examined for TTX. In T. pardalis, the TTX levels were within the range of 1.3-1.6 ㎍/g in the muscles, 18.8-49.8 ㎍/g in the intestines, and 23.3-96.8 ㎍/g in the liver. In T. niphobles, the TTX levels were within the range of 2.0-4.5 ㎍/g in the muscles, 23.9-71.5 ㎍/g in the intestines, and 28.1-114.8 ㎍/g in the liver. Additionally, the toxicity profile of the detected PSTs revealed that dcGTX3 was the major component in T. pardalis and T. niphobles. When PSTs were calculated as saxitoxin equivalents the levels were all less than 0.5 ㎍/g, which is below the permitted maximum standard of 0.8 ㎍/g. These findings indicate that the toxicity of T. pardalis and T. niphobles from the southern coast of Korea is due mainly to TTX and that PSTs do not exert an effect.

The hospice activities in Korea have still stood in the premature stage, although the contemporary hospice program, which professionally accommodates terminally ill patients, appeared in the history 35 years ago. Especially, the availability of the facility hospice is not only poor in number, but also lack of a guideline for the conduct of the facility. Saemmul Hospice has keenly felt the necessity of more facility hospices and has interchanged experiences and informations with people interested in hospice. However, the number of facilities has fallen short of one's expectations, and many problems have been revealed in order to maintain the operation. This paper was written in order to improve these atmospheres and to help more terminally ill cancer patients properly. This paper clarifies in detail the principle of management, the method of practice in each departments of Saemmul Hospice, expected effects and supplemental items. We try to provide concrete and practical informations and to help extensively for all peoples who are to begin or currently working. 1.Facility: It secures, maintain, and manage the hospice environment for all around care of patients effectively. 2.Education and Volunteer: It trains and manages hospice volunteers devoted to hospice. 3.Financial: It manages donation by healthy soul with an effective method. 4.Administration and Organization: It executes the administration efficiently and constitutes the organization to operate. 5.Medical and Nursing: It offers the maximum professional supports to a hospital. 6.Medicine and alternative medicine: It improves the quality of life of patients by medical and pharmaceutical approach and by other possible methods available. 7.Nutrition: It helps patients to have diets in accord with the order of the creation. 8.Belief: It offers spiritual care which allows the profound relationship with God. 9. Funeral ceremonies: Funeral ceremonies may heal grieves of families faced with their deaths. 10. Bereaved families: It supports the families after the deaths of patients. 11.Reception and consultation: It seeks to help the patients who meet the purposes for which Saemmul Hospice is established. 12.Publication: It allows publicity activities for Saemmul Hospice. Facility hospice programs are able to overcome the disadvantages that the other type of the hospice possess, like as the economic burdens of the families, and the patients' losses of comforts of home after being transferred to a hospital. Facility hospice can provide home atmosphere with professional manpower and facilities like hospital to the patients. Therefore, it can also improve patients' qualities of life and make them comfortable death. We anticipate that the hospice program in Korea would be more active to let more people be indebted to maintain the nobel human dignity and to cross beautifully in the most painful process of dying in the journey of their lives.

A long life is the desire of many people. The purpose of this study was to describe long life factors for people aged one hundred and above on Chju island. The research was conducted using a phenomenological method to add understanding to this subject. The field work for this study was done from July, 1997 to February, 1998 on Cheju island. The sample consisted of 10 persons of one hundred or above and 12 families. They were audio-recorded and analyzed using Colaizzi's (1978) method. The results of the present study shows the following: The thoughts of the persons one hundred and above showed ten important concepts; 'dietary regimen', 'mental regimen', 'sleep regimen', 'residence regimen', 'health regimen', 'labor regimen', 'exercise regimen', 'being born', 'filial piety and posterity', 'attachment to life'. Concerning 'Dietary Regimen': Dietary regulation, Preferential food intake, Living on vegetables, Light eating, and concern for longevity in food intake were important. Concerning 'Mental Regimen' : Harmony, Clearheadedness, Mildness, Abstinence, Generosity, Relaxation, Gaiety, Inspiration and Strength were important. Concerning 'Sleep Regimen'; Enough sleeping hours, Sound sleep, Curved sleeping posture, and Comfortable bedding were important. Concerning 'Residence Regimen' ; Clean dwelling, Pleasant surroundings, Thatched house life, Living in the village with good-hearted people, and Regular life were important. Concerning 'Health Regimen'; Temperance of drug, use Proper temperature, Proper humidity, and a Clean body were important. Concerning 'Labor Regimen'; Agricultural labor, Diligence, and Domestic labor were important. Concerning Exercise Regimen': Proper exercise, and Sunbathing were important. Concerning 'Being Born' ; Strong physical constitution, Longevity lineage, and Destiny were important. Concerning 'Filial Piety and Posterity' : Showing respect to a long-lived elder and Reducing anxiety were important. Concerning 'Attachment to Life' ; The desire to live long was important. The following conclusion was made from the above results. Human beings cannot avoid death, but the span of life can be prolonged to the maximum span of human life by wisdom, health care, and proper environmental conditions. As a result, a health regimen must be imposed for longevity such as controling food intake, having positive thoughts, being relaxed, sleeping enough, clean dwelling, taking care of oneself which can improve immunity and resistance to decrease, as well as proper labor and exercise. In addition, when filial piety is served, the desire of longevity and retaining one's youthfulness for a long time can be achieved. These should be done to live long and lead a qualitative life. By the results of this research, the following is suggesed for nursing. To satisfy the basic nursing principle that nursing must be practiced to help people live long, education must be spread to people who are nursed and their family so that they can lead a healthy life. And in nursing elders, nurses must recognize that elders have a strong desire for life, even though they may have negative thoughts about life at times. Therefore nurses have to respect the elders' value of life, and help them improve their self-esteem and self -fulfilment.

편심가새골조(EBF)의 역량설계법에 의하면, 링크가 완전항복 및 변형경화 상태일 때 기둥, 링크외부보, 가새(비소산 부재)는 탄성거동해야 한다. 현행 AISC 341은 역량설계에 필요한 변형도경화계수(SHF)를 1.25로 제시하고 있으나, 실제로 건물이 고층 규모일수록 모든 링크가 이처럼 동등한 수준의 초과강도에 도달할 가능성은 매우 낮아진다. 본 연구에서는 링크의 SHF를 정밀하게 예측하는 방법을 제안함으로써, 역량설계법의 목적을 달성하면서 구조물량을 절감하고자 하였다. 제안한 방법의 효과를 검증하기 위해 선형해석을 2회 수행하여 SHF를 예측하고, 이를 비선형 해석결과와 비교하였다. 다음으로 비선형 해석에 의한 응답을 분석하여 구조물의 한계상태에서 비소산 부재들의 항복 여부를 확인하였다. 그 결과, 본 연구의 방법으로 설계된 구조물은 링크의 SHF를 정확히 예측함으로 인해 물량이 큰 폭으로 절감되었으며, 비소산 부재들도 모두 탄성상태를 만족하는 것으로 나타났다.

Vacuum circuit breaker(VCB) is now emerging as an alternative of gas circuit breaker(GCB) which uses SF6 gas as insulating material whose dielectric strength is outstanding. But we have to reduce SF6 gas because SF6 gas is one of greenhouse gas and efforts to reduce greenhouse gas are now trend of the world. Therefore, we can say VCB is the optimal alternative of GCB because vacuum is environmentally friendly. The vacuum interrupter is the core part of VCB to interrupt arcing current. There are mainly two methods to extinguish arc. One is radial magnetic field (RMF) method and the other is axial magnetic field (AMF) method. We deals with RMF method in this paper. Compared with AMP, RMF arc quenching method has different principle to extinguish arc. In case of RMF method, pinch effect is much larger than AMF method. Because of pinch effect RMF type contact electrodes have the single large spot which is severly damaged and melted while AMF type contact electrodes have small and multiple spots which are slightly damaged and melted. To prevent contact electrode being damaged and melted from high temperature-arc, RMF method uses Lorentz force to move arc. In this paper we calculated and compared the arc driving force of two cases and we analyzed the force acting on each part of arc by means of commercial finite element method software Maxwell 3D. They have 3petals and we considered two cases. One is the case when fixed(upper) and movable(lower) contacts are in mirror arrangement (Case 1). The other is the case when one of two contacts (movable contact) is revolved at maximum angle as possible as it can be (Case 2). And at each case above, we analyzed arc driving force at two positions, position 1 is the closest to the center of contact and position 2 is near the edge of petal on fixed contact. As a result we could find that Case 2 generated stronger arc driving force than Case 1 at position 1. But at position 2 Case 1 generated stronger arc driving force than Case 2. This simulation method can contribute to optimizing spiral-type electrode designs in a view of arc driving force.
