The researches for tumor and the developments for new anti-tumor medicine are being continuously developed in the oriental as well as the west. The principles therapy of anti-tumor activity 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 tumor 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) distinction 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. In clinical study and experimental study, the effects of oriental medicine could be summarized as three that were decreasing toxicity of chemo-therapy, directly suppressing and killing cancerous cell and increasing chemo-effect through preventing metastasis. Improving organic immunity with oriental medicine could be summarized as five that were promoting phagocytosis of macrophage, inducing interferon, promoting formation of immnoglobulin, increasing number of T-cell and promoting transformation of lymphocyte. It is suggested that effective use of immune activating herbs inhibited metastasis and decreased recurrence and then we were able to expect increasing survival rate and improving clinical symptoms and quality of life(QOL) of tumor patients.

Gyeonggi Province is trying to increase the number of public libraries from 100 as of December, 2006 to 150 in 2010. However most of existing public libraries preferred mid-to-large scale libraries, so they were restricted to be located in around a zone of life. For this reason most local residents have been excluded from right to use libraries and have difficulties to get library services for the knowledge and information society of the 21st century. The alternative to the small library is a school library. Both schools and public libraries are located in around a zone of life because residents can get an access to them easily. First, considering that small-scale public libraries of communities usually service about 10,000-20,000 people, I estimate that an open-style school library services 24class, 840people (24class*35people) of elementary school by 2003 Korean Library Standard (edited by Korean Library Association). Second, it requires systematic protection policies so that the open-style school of library can function as a local public library and a part of library cooperation system in accordance with local plans. All the open-style school libraries don't intend to open and we had better consider the suitable service areas. Third, it's desired for the management efficiency that the open-style school libraries being established afterward are divided into a branch-scale, a hall-scale and so on, not being uniform management model. And it also needs that one of them in the area enlarges the scale, and then supports other school libraries. According to these results of the research, as cooperation between the public library policy of a local government and school library policy, it needs a systematic support.

Purpose: We would evaluate the cardiovascular manifestations of the patients with acute organophosphate and carbamate poisoning in the emergency department. Methods: This was retrospectively studied with the review of patient's charts, included total 38 patients were admitted during the past two years in the emergency department of Yeungnam university hospital with the diagnosis of organophosphate or carbamate poisoning. Results: Cardiovascular complications were variously developed in many patients. Electrocardiographic findings were as follows; 4 ($10.5\%$) cardiac arrhythmias included 1 cardiac arrest caused by ventricular fibrillation, 14 ($36.8\%$) sinus tachycardias, 3 ($7.9\%$) sinus bradycardias, and 17 ($44.7\%$) normal sinus rhythms. Conduction disturbances were 23 ($60.5\%$) like as prolonged QTc, 4 ($10.5\%$) ST-T changes, 2 (5.3%) first degree AV block, and 3 ($7.9\%$) right bundle branch block were shown. Other cardiovascular complications were 22 ($57.9\%$) hypertensives, 4 ($10.5\%$) hypotensives, 15 ($39.5\%$) tachycardias, 2 ($5.3\%$) bradycardias, 18 ($47.4\%$) hypoxemics, 12 ($31.6\%$) metabolic acidosis, and 9 ($23.7\%$) pulmonary edemas. Sixteen patients ($42.1\%$) needed ventilatory support because of respiratory paralysis. No patients died in hospital and 36 ($94.7\%$) patients were alive-discharged. Conclusion: Cardiovascular complications are variously in patients with acute organophosphate and carbamate poisoning. Especially, some findings included ventricular arrhythmias, QTc prolongation, hypoxemia, acidosis, and blood pressure changes are known as major precipitating factors to increase the mortality. So, intensive support and aggressive treatment are needed in patients shown various cardiovascular manifestations in the emergency department.

Pylorus-preserving gastrectomy (PPG) is a function-preserving surgery for the treatment of early gastric cancer (EGC), aiming to decrease the complication rate and improve postoperative quality of life. According to the Japanese gastric cancer treatment guidelines, PPG can be performed for cT1N0M0 gastric cancer located in the middle-third of the stomach, at least 4.0 cm away from the pylorus. Although the length of the antral cuff gradually increased, from 1.5 cm during the initial use of the procedure to 3.0 cm currently, its optimal length still remains unclear. Standard procedures for the preservation of pyloric function, infra-pyloric vessels, and hepatic branch of the vagus nerve, make PPG technically more difficult and raise concerns about incomplete lymph node dissection. The short- and long-term oncological and survival outcomes of PPG were comparable to those for distal gastrectomy, but with several advantages such as a lower incidence of dumping syndrome, bile reflux, and gallstone formation, and improved nutritional status. Gastric stasis, a typical complication of PPG, can be effectively treated by balloon dilatation and stent insertion. Robot-assisted pylorus-preserving gastrectomy is feasible for EGC in the middle-third of the stomach in terms of the short-term clinical outcome. However, any benefits over laparoscopy-assisted PPG (LAPPG) from the patient's perspective have not yet been proven. An ongoing Korean multicenter randomized controlled trial (KLASS-04), which compares LAPPG and laparoscopy-assisted distal gastrectomy for EGC in the middle-third of the stomach, may provide more clear evidence about the advantages and oncologic safety of PPG.

In order to analysis of the water pollution of the Anyang stream(one of the biggest branch streams of the Han River) and its main tributaries, the geological and topographical and rainfall features in its basin were investigated. To do this, the water samples were collected 23 points of the upper, mid and down of Anyang stream and its tributaries and were analyzed based on the chemical methods, Korean Biotic Index(KBI) and Saprobien systems. The Anyang stream basin has a characteristic of topographical torrential heavy rainfall like a typical rainfall feature in Korea. The concentration and the outflow rate of rainfall is very different in seasonal, and water pollution in dry season is especially severe. After 1997, although the water quality status of stream has been improved gradually, the concentration of T-N and SS at the upstream is increased due to the deficiency of facility used for collecting wastewater released from industrial factories, livestock farms and residential areas. The mainstream of the Anyang stream is classified into the 5th grade water as polysaprobic water area according to Saprobien system and the biotic index is over 2.5 in overall. Most of tributaries have 1~3 grade water limit with ${\alpha}$- and ${\beta}$-mesosaprobic except the upper and mid streams of Samsung tributary, in which pollution status is the lowest part. Though Sambong tributary is ${\alpha}$-mesosaproboic, biotic index is low because of the appearance of abundant benthos animals in farming and fishing villages.

스프링클러 설비의 설계방법은 크게 3가지로 분류한다. 가지관을 서로 연결하여 사다리형태로 배관을 설치하는 Grid형과 가지관은 연결하지 않고 교차배관만을 연결하는 Loop형 그리고 가장 일반적으로 사용되는 Tree형이 있다. 이 중 Grid형은 아주 간단한 것을 제외하고는 컴퓨터프로그램으로 마찰손실을 계산하여야 하지만 Loop형의 경우는 프로그램의 도움 없이 설계자가 직접 계산하여 마찰손실에 따른 필요압력과 소요유량을 산출할 수 있다. Loop형 설비의 경우 소화수 공급이 2방향으로 분리되어 마찰손실이 작아지고 헤드간 방출압력의 차이가 Tree형보다 작게 되어 살수분포가 우수하게 되며 작은 마찰손실에 의한 소구경의 배관을 사용하여 자재비와 인건비가 절감되므로 Loop형에 의한 스프링클러의 설계가 Tree형 설비에 비해 성능과 경제성에서 우수한 설계 방법이다. 하지만 Loop형 설비의 설계는 설계방법이 잘 알려져 있지 않아 거의 이루어지지 않고 있다. 본 논문에서는 Tree형 보다 우수한 Loop형 설비의 설계방법을 설명하여 많은 설계자가 성능과 경제면에서 우수한 Loop형 설계를 쉽게, 널리 사용하게 하고자 하였다.

Background: Breast Cancer (BCa) is the most common malignant tumour in Mexican women. In BCa, several studies have linked ${\beta}2-adrenergic$ receptor activation with increased tumour growth and progression as related with Epinephrine-NorEpinephrine (E-NE) stimulation. The aim of this study was to describe Beta-Blocker (BB) treatment related with reduction of the risk of metastasis in Mexican patients with BCa. Materials and Methods: We collected data of 120 patients seen at the High-Specialty Naval General Hospital in Mexico City (HOSGENAES), all of these with a histopathological diagnosis of BCa. Four groups of patients were divided as follows: without Systemic Arterial Hypertension (SAH); with SAH treatment with non-selective BB; with SAH treatment with selective BB, and with SAH treatment with other antihypertensive drugs. Chi-square, Mantel-Haenszel, Student t, and ANOVA tests were performed for data analysis. Results: On average, patients were $54.8{\pm}11.8$ years of age. Risk factors such as smoking and consuming alcohol exhibited a frequency of 33 and 36.5% respectively. Clinical stages III- IV were found in 50% of patients, while, 30% of patients had arterial hypertension (n=29 and N=96, respectively) and 17.5% used BB. One hundred percent of patients with arterial hypertension treated with BB for ${\beta}1$ - and ${\beta}2$ -adrenergic-receptors did not present metastasis globally, but patients treated with ${\beta}1$ BB presented 30% of metastasis while patients treated with no BB or without SAH had around 70% of metastasis. Conclusions: In Mexican patients with BCa and SAH treated with non-selective (${\beta}1$- and ${\beta}2-adrenergic$ receptors) BB, a decrease in the risk for metastasis was observed at the time of diagnosis.

This study was carried out among 34 patients who visited Yonsei Dental Hospital from 1996. 1. to 1999. 5 for trigeminal neuralgia. By studying the patient's treatment prior to visiting our hospital, features of trigeminal neuralgia, treatment process of trigeminal neuralgia, prognosis of treatment, consultation with other professions and involvement of surgery, etc., the results are as follows: 1. 67.7% of onset age range from 40s to 60s, and average age is 50.2. 2. Ratio of right to left involvement is 1:2.1, male to female ratio is 1:1.9. 3. Occurrence rate of each branch is V3(44.1%), V2(11.8%), V1+V2+V3(11.8), V1+V2(8.8%). 4. Treatments prior to admission to our hospital are extraction(5.9%), endodontic treatment(5.9%), medication(11.8%), Oriental Medicine treatment(5.9%). 5. Routes of admittance to our hospital are by their preference(55.9%), local clinic referral(32.4%), E.N.T referral(5.9%), Neurology referral(5.9%). 6. 70.6% of patients treated at our hospital who were relieved of symptoms, were referred to Neurology(66.7%) and Pain Clinic(33.3%) for the reason of relapse, side effects of the drug itself, incomplete relief of pain. 7. 2 patients who were referred to medical part showed brain vessels contacting trigeminal nerve root on Brain MRangiography. But pain is being controlled by medication and no specific surgical procedure was carried out. The results show that 17.7% of patients admitted received inappropriate early treatment. In order to relieve tooth loss and patient's psychologic stress due to inappropriate treatment, precise differential diagnosis must be made among local teeth disease and idiopathic facial pain. Medication may show side effects of the drug itself, incomplete relief of pain or relapse of symptoms. Therefore, to treat trigeminal neuralgia appropriately by drug injection, surgery or radiation therapy, consultations among dentists, neurologists and anesthesiologists are required.
