  • During the day time in summer, peak of air conditing load, and electric power management system lies under overloaded condition. The reason is the enlarged peak load value of electric power caused by increased air-cooling load in summer. To prevent load concentration during day time and overloaded condition of power management system, some energy storage methods are suggested. One of these methods is ice storage system. Water has some good properties as P.C.M.(Phase Chang Material) : Its melting point is the range of required operation temperature. It has large specific latent heat and is chemically stable compared to other organic or inorganic substances. It is cheap and easy to treat. This study represents experimental results of heat transfer characteristics of P.C.M. under the outward melting process in a vertical cylinder. We experimented with twelve combinations of conditions, i.e., three different inlet temperatures($7^{\circ}C,\;4^{\circ}C\;and\;1^{\circ}C$), two working fluid directions(upward and downward), and two aspect ratios, H/R(4 and 2). At the inlet temperature of $7^{\circ}C$ and $4^{\circ}C$, there was temperature stagnation region where the temperature of P.C.M. remains constant at $4^{\circ}C$ regardless of aspect ratio and direction of working fluid. This temperature stagnation occurs as the water, at its maximum density, flows down to the lower region. The phase change interface formed bell-shaped curve as the melting process continued. With a new set of conditions(4H/R, inlet temperature $4^{\circ}C$ and $1^{\circ}C$, downward/upwerd inlet direction), the movement of phase change interface was faster when the working flued inlet direction was downward. With the same set of conditions, melting rate and total melting energy were larger when the working fluid inlet direction was downward. The results were reversed when the other sets of conditions were applied.

  • 전통시장은 2008.6월 현재 전국에 1,500개가 있으나, 1996년 유통시장 개방 이후 대형마트, SSM 등에 밀려 전통시장은 위축되어 왔다. 2002년 이후 정부와 지방자치단체는 막대한 예산을 들여 시설현대화 및 경영현대화를 지원하고 있으나 성과가 그리 크지 않다. 그 요인으로는 전통시장 지원제도와 지원방식, 낙후된 시설, 다양하지 못한 상품, 고령상인의 주먹구구식 경영과 부족한 서비스 등으로 볼 수 있다. 본 연구는 전통시장의 지원성과 제고를 위해 공설시장을 전국 전통시장의 활성화 모델로서, 그리고 지역별 거점시장으로서 활용하는 방안 연구에 그 목적을 두었다. 전통시장 중 388개 달하는 공설시장은 주로 지방자치단체가 소유한 것으로 일반시장과 달리 시설, 상품, 서비스 등을 상권에 맞게 최적화시킬 수 있다. 또한 공설시장에 전문 인력을 투입해 시장 활성화 모델 겸 인근 전통시장과 연합하여 공동마케팅, 공동구매 등을할 수 있는 거점시장으로 만들 경우 지원성과 제고에 크게 기여할 수 있다. 본 연구의 한계는 공설시장의 지원제도, 거점시장으로서 전환에 국한된 것이며, 상품구색, 서비스 등의 자세한 활성화 방안은 제시하지 못하고 있다.

  • 우리나라 만화계가 장기침체에 빠져있다는 것은 1990년대 후반부터 누적되어 온 일반적인 시각이다. 이에 정부는 만화산업 육성책으로 2002년부터 만화산업 중장기 발전 5개년 계획을 수립, 집행해 왔다. 그 기간 동안 만화계는 전례 없이 정부의 대대적인 지원을 받은 바 있다. 다가올 2008년부터는 2차 중장기 발전계획이 시행될 예정이다. 그러나 만화계 안팎의 체온은 정부 주무부서와 사뭇 다르게 느껴진다. 1차 계획 시행기간동안 백화점식으로 나열된 사업이 단지 구색 맞추기에 급급했다는 진단이 대세를 이루고 있다. 그러나 근본적으로는 장기 침체에 대한 정확한 진단이 필요하다. 웹만화와 아동학습만화는 유래없는 호황을 구가하고 있다. 만화에 대한 독자의 소비 패턴이 바뀌고 있는 것이다. 따라서 만화산업 중장기 발전 계획은 단지 정부예산 몇 푼을 갈라 쓰는 방안이 아니라 정부, 기업, 민간이 함께 고민하고 플랜을 짜는 종합적이고 입체적인 계획이 되야한다. 또한 선택과 집중을 통해 효율을 높여야한다. 그러기 위해서는 민간단체의 역량을 강화하는 것이 우선이다. 나아가 정부의 금전적, 정책적 지원을 이끌어 내기 위한 로비력도 제고해야한다. 이를 위해 싱크탱크 기능을 담당할 진흥정책 연구 기구의 설립을 제안하며 궁극에는 영화진흥법에 비견되는 만화진흥법의 제정활동을 만화계에 제안한다.

  • Large bowel cancer shows the 4-5th frequency in cancers that occurs in Korea. The western medicine cures the Large bowel cancer by radiation, surgery and chemotherapy. While, Oriental medicine cures the Large bowel cancer by Herb-drugs, acupuncture, moxa and et al. With just one way of treating Large bowel cancer can't be effective remedy. Because each medicine has a strength and weakness, it is effective treatment when two medicine combines and supplement each other. We got the following result about a trend of oriental and western combination treatment for Large bowel cancer through studding records. 1. In Large bowel cancer, colon cancer is referred hematochezia(腸風下血), rectal cancer is refereed enterotoxin(腸毒), and anal cancer is accumulation of pathogens in yin(結陰). 2. The western medicine treats Large bowel cancer patient with surgery first. They need on assembly treatment such as chemical, radiation and immune treatment. In oriental medicine, they treats Large bowel cancer patients with differentiation of symptom and signs and treatment(辨證施治) for example, insufficiency of spleen and stomach(脾胃虛弱), collapse of the spleen-ql(脾氣下陷), stagnation of blood stasis and toxic agent(瘀毒內結), reinforcing both qi and blood(脾血下陷), stagnation of damp-phlegm(痰濕凝結) and cure for them by acupuncture and moxa too. 3. In combination with oriental and western medical treatment princple of Large bowel cancer by each stage is as follows. First stage is cured with radical surgery and herb-drugs without chemotherapy. The intermediate and terminal stage patients is used radiation before surgery, or after palliative surgery cour with chemotherapy, radiation and Herb-drugs. In terminal stage patients, unable for surgery, is used combination between chemotherapy, palliative radiation and Herb-drugs. 4. After radiation surgery, the terminal stage patients who have extensively lymph node metastasis or local contraindication is able to undergo combination of Herb-durgs and chemotherapy. 5. The cure-effect with oriental and western medicine combination treatment was better than that just with oriental or western medical treatment. 6. The merits of oriental and western medicine combination treatment lengthen one's life and diminish the bad effect of chemotherapy and complete radiation treatment, prevent from relapsing, maintain the balance in their environment of body and improve immunity.

  • Objective: In order to find oriental medical therapies on Parkinson's disease and to make a fundamental basis for clinical application, this study was performed. Methods: We reviewed 35 kinds of the ancient and modern text, and related articles. Results: Parkinson's disease is an extrapyramidal disease characterized by akinesia, tremor at rest, rigidity, and slowness of movement. In old oriental medical text, Parkinson's disease is described as Jinjeon(振顫), Chi, Gyeong (痙), Gyejong, Ryeon(攣) and Pyeongo(偏枯), Tantan, Jungbu(中腑症) of Jungpung(中風). According to the text, major pathological causes were Wind(風), Fire(火), Phlegm(痰), and Blood stasis(瘀血). And Parkinson's disease can be classified into four clinical types as liver & kidney yin-deficiency, qi & blood deficiency, retention of phlegm-heat, and qi-stagnation & blood stasis. Standardized acupuncture points are GV20, GB20, GV14 on head, CV12, ST25 on abdomen, GV26, ST7, GB1, S14, LI20 on face, LI4, LI11, TE5, SI3, HT3, LI15, SI6 on upper extremity, and ST36, GB34, SP6, LR3, KI1, GB30, BL40 on lower extremity. Other methods, such as scalp acupuncture, electro-acupuncture, and herb-acupuncture, can be applied to treat Parkinson's disease. Conclusions: We find out that there are oriental medical concepts related with Parkinson's disease such as Jinjeon(振顫), Chi, Gyeong (痙), Gyejong, Ryeon(攣) and Pyeongo(偏枯), Tantan, Jungbu(中腑症) of Jungpung(中風), of which major causes are Wind(風), Fire(火), Phlegm(痰), and Blood stasis(瘀血). We can also apply many effective acupuncture points and acupuncture therapies according to differential diagnosis, for example, liver & kidney yin-deficiency. qi & blood deficiency, retention of phlegm-heat, and qi-stagnation & blood stasis.

  • 네비게이션의 최단 경로 탐색 알고리즘은 일반적으로 Dijkstra 알고리즘에 기반을 두고 있으며, 가중치로 단지 길이 (거리) 만을 고려하고 있다. 거리 기반의 Dijkstra 알고리즘은 출발 노드부터 시작하여 그래프의 모든 노드에 대한 최단 경로를 결정하기 때문에 일반적으로 노드의 수 - 1회를 수행해야 하며, 알고리즘 수행에 많은 메모리가 요구된다. 또한, 거리에만 기반하기 때문에 전방에 차량사고로 인해 병목현상이 발생하였을 때 우회도로를 탐색하는 기능이 없어 항상 동일한 경로만을 탐색한다. 이러한 문제점을 해결하고자, 본 논문은 도로 등급 (고속도로, 국도, 지방도 등)을 고려하지 않고, 속도 기준 (원활, 지체 서행, 정체, 사고 통제 등)도 적용하지 않으며, 단지 도로별 주행시간 (주행속도 ${\times}$ 거리)을 고려한다. 이는 사고, 지체, 공사 등으로 인해 동일한 거리의 도로도 다른 시간이 소요되는 현실성을 반영하여 우회도로를 탐색할 수 있는 장점이 있다. 제안된 알고리즘은 특정 도로에서 사고가 발생하였다고 가정한 경우에도 도로의 통행속도를 실시간으로 반영함으로서 돌발지점을 우회하여 목적지 까지 최단시간 내에 도달 할 수 있음을 증명하였다.

  • In this study, we selected some herbal formulation about a series of Chijasi-tang in Dongeuibogam by using web-based open program;Prescription Lineage Graph (http://164.125.206.43/PrescriptionLineageGraph.aspx). And we compared and analyzed the changes of efficacy, major target symptoms of each herbal formulation according to compositional variation of each herbal formulation. Chijasi-tang, first appeared in Sanghanlun, consists of Capejasmine and Fermented soybean, and it is mainly used to treat insomnia due to vexation, heartburn and yellow greasy tongue fur. Capejasmine can clear away irritable feverish sensation in chest by flowing downward the heat, and Fermented soybean can disperse stagnated heat throughout the chest by expelling stagnated heat from the exterior In the case of the heat stagnation caused by relapsing of disease due to overstain, Chisijisil-tang can be used. And if symptom appear more on the upper or exterior than a case of Chisijisil-tang, Seosisi-tang could be more suitable, if half exterior and half interior, Omae-tang could be for it. In addition, if symptom caused by relapsing due to improper diet, Chisijihwang-tang could be proper formulation. In the case of the heat stagnation body inside and jaundice, if it is caused by alcohol, Chijadaehwang-tang could be used for the purpose of urgent purgation, Galchul-tang would be suitable for helping the function of the spleen and the stomach and for treatment of damp-heat of the spleen and the stomach. And if it is caused by pandemic infection, Jangdal-hwan would be good formulation for it. Samhwangseokgo-tang and Yangdokchija-tang could be appropriate formulation for the raging of noxious heat and pathogenic fire caused by febrile disease with toxic yang. Daehwangeum-ja is for severe constipation due to heat-dryness with stagnated fever, Haebaek-tang is appropriate for severe diarrhea due to heat type change of Soeum. According to the result of our investigation, although there are various target causes and symptoms of each herbal formulations, whatever pathogenetic cause is, the stagnated heat in interior side is the basis of symptoms. Therefore, the purpose of including Chijasi-tang in composition of each herbal formulation is treatment of the stagnated heat. For such reason, on the fundamental or ancillary basis of Chijasi-tang plus some herbs for each therapeutic purpose.

  • Gastric cancer shows the most high friquency in cancers that occurs in Korea. The western medicine treatment for gastric cancer has radiation and surgery, chemical treatment. While, oriental medicine cures the gastric cancer by herb-drugs, acupunture , moxa and srigma. With just one way of treating gastric cancer can't be effective remedy. Because each medicine has a strength and weakness. Thus, it is effective treatment when two medicine combins and supplement each other. We got the following result about a trend of oriental and westernal combination treatment for gastric cancer through studing records. 1. The western medicine treats gastric cancer patient with surgery first and right after surgery. They need on assembly treatent such as chemical and immune treatment. In oriental medicine, they treats gastric cancer patients with differentiation of symptone and signs and treatment(辨證施治)[for example:incoordination between liver and stomach(肝胃不和), insufficiency of spleen and stomach(脾胃虛弱), stagnation of blood stasis and toxic agent(瘀毒內阻), deficiency of yin by stomach heat(胃熱傷陰), reinforcing both qi and blood(氣血雙虧), stagnation of damp-phlegm(痰濕凝結)] and cure for them by acupuncture and stigma, too. 2. In combination with oriental and western medical treatment principle of gastric cancer by each stage is as follows. First stage and second stage gastric cancer is cured with radical surgery mainly. After operation, the herb of invigoration of the spleen(健脾), coordination of the stomach(和胃), and smoothing the liver and regurating the circulation of qi(疏肝理氣), is used for good gastroenteric condition. The second stage patients can be concidered using in combination with chimical treatment. The third stage gastric cancer is treated with radical surgery or with temporizing surgery. After those surgery, herb-drugs treatment is used jointly. The fourth stage patients who have no extensively metastasis or local contraindication can undergo temporizing and curcuit surgical operation. Herb-drugs and chemical treatments are used together for patients after operating. If he has operating contraindication, he would be treated with herb-drugs and chemical treatment. 3. In case of using in combination with oriental and western medical treatment as follows. As for herb-drugs with chemical treatment, reinforcing both qi and blood(補益氣血), invigorate the spleen and the stomach(健脾和胃), reinforcing liver and kidney(滋補脾腎), clear out the heat and relieve the toxic agent(淸熱解毒), can be used and with radiation treatment, clear out the heat and relieve the toxic agent(淸熱解毒), promoting the production body fluid and moisturizing the vicera(生津潤燥), reinforcing both qi and blood(補益氣血), invigorate the spleen and the stomach (健脾和胃), reinforcing liver and kidney(滋補肝腎) etc, can be used. 4. According to the research of oriental and western medical combination treatment are the 5-year-survival degree with oriental and western medicine combination treatment was for better than that just with oriental or western medical treatment. Especially, it has good effect on the third, fourth stage gastric cancer. That is, the middle and the end of stage gastric cancer. 5. The merits of oriental and western medicine combination treatment are lengthers one's life and diminish the bad effect of chemical treatment and radiation treatment be near completion, prevent from relapsing, maintain the balance in their eveirenment of body and improve immunity.

  • Recently, the occurrence and death rates of cancer have increased rapidly. Metastasis and recurrence is the most important factor of death from cancer. So inhibition of recurrence and metastasis can increase the cure rate of cancer disease. At the basic chinese traditional medicine(TCM), there are a lot of theory related to neoplasm treatment. The metastasis and recurrence of neoplasm was the basis of yudu(餘毒) on remained neoplasm cell and stagnation of blood, thermotoxo, phlegm, asthenia of healthy enerngy and stagnation of vital energy. The principles therapy of neoplasm on metastasis and recurrence was based on knowledge of the method of support the healthy energy and strengthen the body resistance, promote blood circulation to remove blood stasis, clear away heat and toxic materials, dissipate phlegm and disperse the accumulation of evils. But the major clinical features of neoplasm was to be considered in developing a treatment plan include (1) distinguish between clinical and pathologic staging - acute and chronic, (2) classification of pathologic pattern, and (3) distingction of body situation : for examples asthenia - sthenia etc. It was most important to distinguish between supporting the healthy and eliminating the evil factors and to treat differently at the root and the branch cause of a neoplasm. This paper's results indicate that identification and effective use of THM can inhibite netastasis and recurrence and then it will help increasing survival rate. Also as BioTechnology(BT) has developed rapidly nowadays, as genes related to cancer have revealed. So it will give rise to the development of searching the mechanism of herb medicines which have inhibition effects of metastasis and recurrence.
