전자상거래를 위한 XML 메시징 시스템 개발

임종선,주경수 한국로지스틱스학회 2002 로지스틱스연구 Vol.10 No.1

XML은 표준화와 운영체제 중립적이라는 특성 때문에 전자상거래에서 중요한 위치를 차지하며, 이미 많은 전자상거래 시스템에서 이용되고 있다. B2B 전자상거래분야를 위해서는 기업간 비즈니스에 대한 업무 규칙과 절차가 표준화되어야 한다. 그러나 기업들이 표준화된 XML 문서를 사용하는 것이 아니라 기업의 실정에 맞게 시스템을 구축하여 기업간 XML 문서 전달을 하고 있어, 이에 따라 많은 문제점이 나타나고 있다. 이러한 요구를 기반으로 많은 조직과 기업에서는 XML을 기반으로 하는 전자상거래 표준화 작업을 프레임워크 형태로 진행하고 있다. 본 논문에서는 XML로 서비스를 요청하고 서버가 해당 서비스를 처리하는, XML 메시징 시스템을 설계 및 구현하였다. 본 메시징 시스템을 전자상거래 시스템에 적용하여 효율적으로 이용할 수 있을 것이다. Because XML is a W3C standard and has characteristics like platform-independent, it has a critical role in e-commerce. Business rules and procedures should be standardized for efficient B2B integration. But a lot of companies are its own XML documents instead of standard documents. Therefore many organizations try to make standards for e-commerce based on framework. In this paper, XML messaging system is designed and implemented. Client requests service in XML and server returns response in XML in this system. So we can more easily and efficiently build E-Commerce based on this XML messaging system.

초음파 센서를 이용한 형상기준지도 작성에 관한 연구

임종환,강병수 제주대학교 산업기술연구소 2000 尖端技術硏究所論文集 Vol.11 No.2

This paper presents a sonar based map building method. The environment is a room or an area inside a building, which is composed of four types of geometric primitives(corners, edges, cylinders, and walls). We also assume the environment can be modeled into two dimensional map in terms of planes(walls), points(corner and edge), and circle(cylinder). In a real world where most of the object surfaces are specular ones, a sonar sensor suffers from a multipath effect which results in a wrong interpretation of the location of an object. To reduce the effect and uncertainty, the method employs a simple thresholding technique for extracting circular are features called regions of constant depth(RCD) from scanning sonar data. The usefulness of the approach is illustrated with the results produced by sets of experiments.

Air Stripping에 의한 트리할로메탄의 제거

임종주,이의수 동국대학교 산업기술환경대학원 1996 산업기술논총 Vol.3 No.-

The removal of trihalomethanes (THM) by air stripping was examined. Experimental variables studied for air stripping were air flow rate, initial THM concentration, and residence time. In batch aeration experiments, CHCl_3 rejection level was found to increase with an increase in air flow rate., residence time and temperature. In continuous aeration experiments, both rejection levels of CHCl_3 and CHBr_3 increased with an increase in air flow rate. For the maximum air flow rate used (air-to-water ratio=20), about 75% or the initial CHCl_3 was removed by aeration whereas only about 40% of the initial CHBr_3 was removed under the same experimental conditions. When doubling the residence time in each experiment, rejection levels of CHCl_3 and CHBr_3 were shown to be increased by a factor of 1.8 and 1.2 respectively. The CHCl_3 removal level was affected by its intial concentration and the effect was found to become more significant as higher air-to-water ratios were used during aeration. On the other hand, CHBr_3 removal was not greatly affected by the initial CHBr_3 concentration. Preliminary experimental results suggested that aeration could be an effective method for the removal of the more volatile THM component, CHCl_3 but some other method such as carbon adsorption must be accompanied in order to obtain a substantial removal of the less volatile THM component, CHBr_3.

Tumorous lesion of intra- and suprasellar area showed unique clinical pictures and also was very hazardous and difficult to remove surgically because of the surrounding important anatomical structures. Here, authors analyzed 28 confirmed tumor of this area during last two and half years retrospctively. Histopathologically, 28 cases were classified in 14 pituitary adenoma cased6 cases of non-functioning adenoma, 1 GH-secreting adenoma and 7 cases of prolactinoma), 7 craniopharyngioma cases, 3 meninigioma cases and each one case of germinoma, Rathke's cleft cyst, pituitary abscess and hamartoma. Sexual incidence was 6 : 22 in male vs female ratio. Twenty two cases were measured its diameter over 2cm and they extended to suprasellar area in all cases. Five cases of microadenoma were analyzed and they were all enclosed in sella turcica. Visual impairment was the most frequent and prominent clinical symptom. of which incidence was 78.57% (22 cases). The next frequent symptoms were headache and generalized lethargy. Diabetes insipidus was a presenting symptom in 4 cases and hydrocephalus was noted in 4 cases preoperatively. Surgical intervention was carried out in 23 cases, by the way, the performed type of surgery in 21 cases was a conventional transcranial frontotemporal(pterional) microsurgical method. Post-operatively, diabetes insipidus was complicated in 78.26 % and pituitary hypofunction was noted 34.78%. Two cases of intracranial hemorrhage was developed after surgery and one was died. Through 6 to 28 months follow up. 82.1 % of cases were improved in its clinical status including 7 cured cases.

쑥 양침액의 투여와 관련된 변화를 관찰한 결과, 전 시험기간을 통해 단회투여 후 14일 동안 일반증상, 치사율, 체중변화, 부검소견, 장기중량변화, 혈청생화학적 분석등의 각종 지표에 의한 안전성을 평가했을 때 1× 실험군에서는 대조군에 비해 유의한 변화를 관찰할 수 없었으며 10×쑥약침액 투여 후 관찰된 체중의 감소, 혈정생화학적 수치의 유의한 변화는 과용량의 시험물질에 의한 영향으로 생각된다. 한편, 5×, 10×의 쑥약침액을 투여한 실험군에서 활동력 저하, 호흡수 감소, 졸음 및 무기력등의 임상증상이 관찰되었는데 이는 중추신경계 억압에 의한 증상으로 보고??되어 있다. 또한, 혈액내 혈청을 분리하여 간세포 이상의 지표로 사용하고 있는 GOT, GPT를 측정하였고 혈청 중의 total enzyme을 측정하여 LDH의 활성치를 계산, 이것을 심폐질환, 혈액질환, 간질환의 유무를 알아내는 지표로 사용하였으며 간염, 간경변, 골질환의 유무를 알아내는 지표로 사용하는 ALP-s를 측정하였다. 농도에 따른 쑥 약침액의 영향을 알아본 결과 쑥 약침액을 대조군에 비하여 단회투여시 1×의 농도에서는 대조군에 비해 유의한 차이를 나타내지 않았으나 5×, 10×의 농도의 실험군에서는 상당히 유의한 차이를 나타냄으로써 쑥 약침액의 과용량의 투여는 마우스의 간세포, 골세포, 심폐기관 등에 유해작용을 일으킬수 있음을 알 수 있었다. 본 실험을 통해 1×의 쑥 약침액의 용량은 급성 독성시험 결과 무해한 용량으로 판단되며, 5×이하의 용량군을 세밀히 나누어 검토할 필요가 있다고 판단된다. Acute toxicity of Artemisia Nakai Aqua-acupuncture Solution(ANAS) as studied in ICR mice. Mice were injected inrtapeitoneally with single dose of 1×, 5×, 10× ANAS and toxicological responeses were observed for consecutive 14 days. Mortality, clinical signs, body weight changes, organ weight, and serum chemistry were performed. The mortality and body weight changes of mice treated with 1× and 5× ANAS were not affected during the experimental periods. With the 10? ANAS treatment, dead animals and changes of body weight, organ weight and serum biochemical values were observed during the experimental period. There results suggest that 1× ANAS causes no toxicity that 10× ANAS causes toxicity in acute toxicity test.

Background : Cardiac arrest is a potent stimulus for the release of endogenous catecholamine and high plasma catecholamine concentration has been reported during cardiopulmonary resuscitation(CPR). Few data were present about the clinical effect of high plasma catecholamine and endogenous catecholamine response to exogenous epinephrine administration during CPR. Purpose : This study was designed to evaluate endogenous catecholamine response to cardiac arrest and exogenously administered epinephrine during CPR. Method : In 21 cardiac arrest victims, blood sample for epinephrine and norepinephrine was drawn before and 1 minute after each epinephrine administration during CPR. 1mg of epinephrine was administered immediately after intravenous access and 3 minute interval during CPR. Plasma catecholamines were quantitated by high-performance liquid chromatography. Result : Baseline plasma epinephrine concentraqtion was higher in patients with cardiac arrest than normal controls (985±1627 vs 194±173 pg/ml, p<0.05). Baseline plasma norepinephrine concentration was also elevated in patients with cardiac arrest than normal controls, although statistically insignificnat(1965±4915 vs 360±250 pg/ml). Plasma epinephrine concentration in cardiac arrest patients was significantly elevated after exogenous administration of epinephrine, but its response was blunted after the third does of epinephrine. Plasma norepinephrine concentration in cardiac arrest patients was also elevated, but its response was observed only after the first epinephrine administration. Plasma epinephrine concentration was persistently higher in patients with return of spontaneous circulation (ROSC) than patients without ROSC. there was no significant difference of plasma norepinephrine concentration whether spontaneous circulation was restored or not. Endogenous epinephrine response to exogenous epinephrine was not observed in patients having prolonged arrest time over 20 minutes. Conclusion : Results of this study suggests that significant amount of catecholamine is released by exogenous epinephrine administration in spite of high plasma catecholamine concentration, and degree of endogenous catecholamine response influences resuscitation outcome.

There are a lot of shopping malls in Internet and most of consumers want to buy good goods in cheap price through the shopping malls. To support them, many sites for price comparison are constructed. But man or woman search many shopping malls and insert their price informations into database that the price comparison sites own. To overcome this disadvantage, virtual shopping malls are builded. These virtual shopping malls are connected and cooperated a lot of affiliated existing shopping malls for the cheapest price information. But, these virtual shopping mall are connected to those existing shopping mall in synchronous. So if they are connected to many existing shopping malls, we have to wait long time because of searching for many existing shopping malls. In this paper, we designed and implemented a virtual shopping mall that connect to many existing shopping malls in asynchronous. For a asynchronous communication between this virtual shopping mall and many existing shopping malls, we used JMS(Java Message Service) that is a standard Java API for MOM(Message-Oriented Middleware)

In the guidelines of Advanced Trauma Life Support(ATLS), essential plane roentgenograms (chest AP vIew, cervical spine lateral view and pelvis AP view) are recommanded when primary survey and resuscitation phase are finished in care of multiple injured patients. A prospective study was carried on 376 multiple trauma patients who admitted to Wonju Christian Hospital from July, 1995 to October. We analyzed clinical significance of essential X-ray in multiple trauma patients, and classified the patients by their status of mentality. The one is alert group when their Glasgow Coma Scale(GCS) is over 13 point, the other is disoriented mentality group when their GCS are below 12 point. The alert group was redivided by presence of clnical symptoms and/or signs, and clinical significances of essential X-ray were analyzed. Among the 376 patients, 330 patients are alert group that their GCS score is over 13 point and 46 patients are disoriented group who's GCS were below 12 point. The detection rate of abnormality in essential X-ray is higher in disoriented group than alert group(cervical-spine lateral view : 13.5% vs 3.0% cheat AP view : 0.4%, pelvis AP view : 0%). This study suggests that their are no needs of taking essential X-ray in patients who is alert in mental state and have no clinical symptoms and/or signs.
