  • Quality of the web service is one of the most important elements as various web services provide diverse functionality, and therefore, it is more and more difficult to satisfy customer's needs. Since the existing UDDI registry provides the basic information such as name and URL of a web service, users are having hard times to choose and customize their web service. In this paper, we propose an extended UDDI architecture for providing quality data of a web service. And in this architecture, we used an automated collection technique of data for testing web service which provides quality information to the users, including response time, throughput, availability, reliability and accessibility. With this new architecture, users and web developers can benefit from web services that customize information for the users and this ensures reliability of web-based applications.

  • Adamantinoma is a rare malignant tumor and approximately 85% of cases occur in the tibia. In 1985, Moon and Mori reviewed the world literature and identified 195 cases. A 59-year-old woman was presented with nonspecific pain on left leg after trauma. Radiographic finding showed well-circumscribed soap bubble appearance with areas of sclerosis in diaphyseal region of the tibia. Magnetic resonance imaging and biopsy was performed for diagnosis. Histologically, the lesion was compatible with adamantinoma. Wide resection with bone graft was performed. There was no recurrence at 3 years follow-up. We report a case of adimantinoma that arose in diaphyseal region of the tibia with review of literature.

  • Especially in NICU(Neonatal Intensive Care Unit), handwashing is an important factor in decresing nosocomial infections due to reduced immunity, prematurity and various invasive procedures. The purpose of this study was to investigate the basic characteristics related to handwashing by NICU nurses. It was composed of three parts ; questionnaire survey I (genoral characteristics of handwashing), questionnaire survey II(the awareness degree of handwashing importance) and actual performance. This study was performed from Oct. 8 to 14 in 1994. The results of this study were as follows ; 1. Frequency of handwashing were different by shift of working about 47.1% of the respondents. They were washing most frequently during day-shift about 75% of above. According to self evaluation to handwashing frequency, 64.7% of the respondents said their frequency of handwashing was inadequate, because of being too busy.(45.1%), bothering caused by detergent or disinfectant(17.6%), and too far from handwashing facilities(17.6%). 2. The most common handwashing agent was soap(88.2%), 52.9% of the subjects experienced adverse effects after handwashing ; rough hand(44.5%), dryness(33.3%) All subjects washed their hands with running water, and 70.6% of the subjects washed upto wrist. In duration of handwashing, 52.9% of subjects washed hands 5 to 10 seconds, 29.5% of them did 11 to 15 seconds. 3. 29.4% among subjects had participated to take in the handwashing educational program. About 60% responded they would like to take the course of handwashing if possible. 4. The important nursing activities that need handwashing were chaning of caring ostomy, suctioning, chaning IV dressing site. On the other hand, they responded handwashing was not essential before dealing with omitus, before and after transfering machine, before chaning diaper(stool) 5. Handwashing performance was 61.7%. Among seven nursing activities, suctioning(73.4%) was the highest, the next was dealing with discharge or sampling(71.1%), the lowest was bathing(34.6%). The performance was better after(70.2%) nursing activities that before(52.5%), and day(63.6%) or evening(68.3%) shift than night(56.7%)

  • IoT devices including smart devices are connected with internet, thus they have security threats everytime. Particularly, IoT devices are composed of low performance MCU and small-capacity memory because they are miniaturized, so they are likely to be exposed to various security threats like DoS attacks. In addition, in case of IoT devices installed for a remote place, it's not easy for users to control continuously them and to install immediately security patch for them. For most of IoT devices connected directly with internet under user's intention, devices exposed to outside by setting IoT gateway, and devices exposed to outside by the DMZ function or Port Forwarding function of router, specific protocol for IoT services was used and the devices show a response when services about related protocol are required from outside. From internet search engine for IoT devices, IP addresses are inspected on the basis of protocol mainly used for IoT devices and then IP addresses showing a response are maintained as database, so that users can utilize related information. Specially, IoT devices using HTTP and HTTPS protocol, which are used at usual web server, are easily searched at usual search engines like Google as well as search engine for the sole IoT devices. Ill-intentioned attackers get the IP addresses of vulnerable devices from search engine and try to attack the devices. The purpose of this study is to find the problems arisen when HTTP, HTTPS, CoAP, SOAP, and RestFUL protocols used for IoT devices are detected by search engine and are maintained as database, and to seek the solution for the problems. In particular, when the user ID and password of IoT devices set by manufacturing factory are still same or the already known vulnerabilities of IoT devices are not patched, the dangerousness of the IoT devices and its related solution were found in this study.

  • Purpose: The purpose of this study is to identify factors related to compliance with respiratory infection preventive behaviors including hand washing, cough etiquette, and oral hygiene of older adults. Methods: A cross-sectional study was conducted with a convenience sample of 100 older adults (mean age: $76.11{\pm}6.35$ years, female: 86.0%). Data were collected from a community senior center through face to face interviews by using instruments including measuring knowledge, perceived threat, self-efficacy, compliance with respiratory infection preventive behaviors. Results: The mean score of knowledge was 7.52 out of 13 in total. The compliance with hand washing with soap was 6.0% for 8 or more times per day. Among the participants, 12.0% adhered to the cough etiquette. Sixty-two older adults (62.0%) didn't use interdental brushes or floss at all. The stepwise linear regression indicated that age and self-efficacy for respiratory infection preventive behaviors were significant factors and explained 24.0% of the compliance with hand washing and the cough etiquette. Education level, cancer diagnosis, and self-efficacy for respiratory infection preventive behaviors were significant predictors of oral hygiene. The factor with the greatest effect was self-efficacy in the two models. Conclusion: The findings suggest that it is necessary to improve compliance with respiratory infection preventive behaviors among older adults using senior centers. In order to enhance the compliance, it is necessary to develop nursing programs based on the self-efficacy for respiratory infection preventive behaviors in the senior centers.

  • The almost similar degumming effect was obtained by using oxalic acid instead of phosphoric acid, which also improves waste-water treatment. At this point, solution of Phosphoric, Acetic, Citric, Oxalic, and Nitric acid were used for degumming of rapeseed and soybean oil. Compared with Phosphoric(PA) and Oxalic acid(OA) were showed a simillar degumming effect in these vegetable oils. In rapeseed oil of 85% PA treating group and 5,10% OA fretting group, residual soap and phosphorus content in neutralized oil, color in bleached oil, and peroxide value and fatty acid content in deodrized oil were showed to simillar result. Soybean oil as well as rapeseed oil were showed to similar result. As a result, we could comfirmed substitutive possibility, which change PA into OA as a degumming agent. In the other hand, waste waters were obtained from 55% PA treating group and 10% OA treating group. Analytical result for this waste waters has showed a wide difference, especially in the BOD and COD. The amount of treating agents and time required in the precipitation seperation and chemical treatment each 3 and 1.7 times, which is PA treating group than OA treating group. We have investigated both the simillar degumming effect by OA solution and an alternative the pollution program means of a chemical treatment process is not possible.

  • The purpose of this study was, to estimate the detergency of commercial detergent and to examine the interrelationship between detergency and detergent characteristics, detergent concentration, fiber characteristics, and Rolling-up phenomenon which is the major removal mechanism of oily soil. A mixture of oleic acid-olive oil was used as oily soil. The detergency was estimated by analysis of oleic acid on cotton ana polyester fabrics before and after washing by means of liquid scintillation counting. The Rolling-up of oily soil from PET film was observed and change of contact angle and removal time were measured. The results were as follows ; 1. In the case of soaps and powder synthetic detergents, the optimum concentrations we-re about $0.2\~0.3\%$. And detergencies of liquid synthetic detergents were considerably low, and the detergency was continually increased up with increasing concentration to $0.5\%$, which seemed to be caused by the lower pH than that of soap and powder synthetic deter-gent solutions. 2. As the effect of external or internal fiber structure; the detergency of cotton was lower than that of polyester. 3. In the observation of Rolling-up, the contact angle increased and the Rolling-up time became shorter with increasing detergent concentrations ($0.05\~0.5\%$). And it was confirmed that detergency was increased with Rolling-up effect. In addition, the study on the actual laundry condition was studied using the questionaire. From the results, about $76\%$ of households used the concentration of detergent roughly or excessively and housewives were highly concerned on the recommended dose, but grade of practice were very low.

  • The success of Newton's Gravitational Theory has influenced the theory of capillarity, beginning in the early nineteenth century, by providing a major model of molecular attraction. He used the equation of the attraction of spheroids, which is expressed by second order partial differential equations, to utilize this analogy as the same kind of a particle's force, between gravitational, refractive force of light, and capillarity. The solution of the differential equation corresponds to the geometrical figure of the vessel and the contact angle which is made by the fluid. Unknown abstract functions $\varphi(f)$ represent interaction forces between molecules, giving their potential functions. By conducting several kinds of experimental conditions, it was found that the height of the ascending fluid in the tube is inversely proportional to the rayon of the tube or the distance of the plate. This model is an essential element in the theory of capillarity. Laplace has brought Newtonian mechanics to completion, which relates to the standard model of gravitational theory. Laplace-Young's equation of capillarity is applicable to minimal surfaces in mathematics, to surface tensional phenomena in physics, and to soap bubble experiments.
