The number of internet users is growing at a rapid rate and this means users now have to remember passwords for many different accounts. The side effects of this increase of user accounts is that users are putting password usability before password security in order to remember these passwords. This paper outlines a novel password creation scheme for creating strong, secure unique passwords that are easier for users to remember on multiple sites. The scheme includes features to more easily create a secure password and recall this password, whilst including multiple layers of security against a targeted attack by an adversary. Results showed that users who did not use a scheme had a much lower login success rate for their accounts than the users who used the created scheme. They also showed that the average password length for each group of users was the same meaning the created scheme passwords in this sample has no greater protection against brute-force attacks, but in terms of dictionary and hybrid attacks the scheme passwords generally seemed to have a lot more protection.

Text-based passwords are widely used for the authentication of digital assets. Typically, password security and usability is a trade-off, i.e. easy-to-remember passwords have higher usability that makes them vulnerable to brute-force and dictionary attacks. Complex passwords have stronger security but poor usability. In order to strengthen the security in conjunction with the improved usability, we hereby propose a novel graphical authentication system. This system is a picture-based password scheme which comprises of the method of image splicing. Authentication data were collected from 33 different users. The usability of the method was evaluated via a comparison between the number of correct and incorrect authentication attempts and time taken. Additionally, a comparison was made between our proposed method and a complex text-based password authentication method using the authentication success rate. Authentication using image splicing proved to be resilient to brute-force attacks since the processing of images consumes a voluminous password space. The evaluation of the usability revealed that graphical passwords were easy-to-remember, resulting in a higher number of correct attempts. The proposed method produced 50% higher success rate compared to the text-based method. Findings motivate the use of the proposed method for securing digital assets.

Background: The aim of this study is to report our results in main stem vein closure using the bipolar radiofrequency induced thermotherapy (RFITT) system and the 1064nm Nd:Yag laser. Patients and methods: 44 incompetent main stem veins (37 great saphenous veins, one lesser saphenous vein, and 6 anterior accessory saphenous veins) in 29 patients were treated using RFITT. 53 incompetent main stem veins (45 great saphenous veins, 4 lesser saphenous veins, and 4 anterior accessory saphenous veins) in 43 patients were treated endovenously with 1064 nm Nd:Yag laser. All patients underwent postoperative duplex scanning within a month after procedure, as well as a short interview regarding postoperative discomfort. Results: In main stem veins treated with RFITT, the success rate within the first month was 86,4 % (38 out of 44 veins). Complete failure rate was 13,6 % (6 out of 44 veins). In 53 main stem veins treated by 1064 nm Nd:Yag laser, the success rate was 100 %, consisting of 98,1 % complete success (52/53 veins), and 1,9 % partial success (1/53 veins). None of the patients treated with RFITT experienced postoperative adverse effects, whereas 13/43 (30,2 %) patients treated with laser had to use oral analgesics after the treatment, and 21/43 (48,8 %) patients reported transient skin changes, such as bruising or skin redness. Conclusions: RFITT system was fairly efficient in the short term for closure of main trunk veins, whereas longer term results are still scarce. Postoperative side effects of RFITT were minimal. 1064nm Nd:Yag laser, according to short term results, proved to be very effective for main stem vein closure. Postoperative side effects related to 1064 nm Nd:Yag endovenous laser treatment proved to be minor, transient, and acceptable.

Background: Abortion is the most common entity in the practice of obstetrics and gynaecology. Different methods and modes have been opted for until now to find an effective regimen with the least complications. We have tried the minimal dose (100 mg) of Mifepristone (PO) instead of the presently recommended 200 mg for medical abortion in early first trimester cases. Objectives: The objective of the study was to determine the efficacy of low dose (100 mg) Mifepristone for medical termination of early pregnancy with oral Misoprostol 800 μg, 24 hours later.Design: A prospective analytical study was conducted on a population of 82 early-pregnant patients who have requested medical abortions.Method: Pregnant women of less than 56 days gestation age from their last menstrual period, requesting medical abortion were selected over a period of 14 months from January 2007 to March 2008. They were given 100 mg Mifepristone orally on Day-1, followed by 800 μg Misoprostol orally 24 hours later on Day-2, keeping the patient in the ward for at least 6 hours. Abortion interval, success rate, post-abortion bleeding and side-effects were noted. Success was defined as complete uterine evacuation without the need for surgical intervention.Results: The total success rate of this minimal dose Mifepristone regimen was 96.25%. Pain and nausea were the predominant side-effects noted. In total 72 (90%) women had completely aborted within 5 hours of taking Misoprostol. Three (3.75%) women only required suction aspiration, hence termed as failed medical abortion. The abortion interval increased with the gestation age. All three failures were of the more-than-42-day gestational age group. The overall mean abortion interval was 4.68 ± 5.32 hours.Conclusion: Mifepristone 100 mg, followed 24 hours later by Misoprostol 800 μg orally, is a safe and effective regimen for medical abortion.

Introductions: The termination of second trimester pregnancy is challenging due unfavorable cervix. This study evaluate the efficacy and maternal side effects of intravaginal misoprostol for termination of second trimester pregnancy. Methods: During one year period from 15th June 2011 to 14th June 2012, Department of Obstetrics and Gynaecology of Patan Hospital, women admitted for second trimester termination of pregnancy for fetal congenital anomalies and intrauterine fetal demise were studied using the International Federation of Gynaecology and Obstetrics recommended doses of vaginal misoprostol. For congenital anomalies, 400 mcg 3 hourly to a maximum of 5 doses were used. For fetal demise, gestational age of 13-17 weeks received 200 mcg every 6 hourly to a maximum of 4 doses, and 18-26 weeks dose was adjusted to 100 mcg. Main outcome measures included success rate of abortion within 48 hours, induction to delivery interval and maternal side effects. Results: There were 40 patients during study period. Success rate for termination of 2nd trimester pregnancy within 48 hours was 88.8% for congenital anomalies. For fetal demise, success of termination was 90.9% at 13-17 weeks and 100% at 18-26 weeks. Median time from induction to delivery was 26.8 hours for congenital anomalies. For fetal demise, it was 18 hours for 13-17 weeks was and 24 hours at 18 to 26 weeks respectively. Abdominal pain was seen in all doses of misoprostol. Conclusions: Vaginal misoprostol is an effective method for termination of second trimester pregnancy. Plain Language Summary: The study was conducted to see the effectiveness of vaginal misoprostol for termination of second trimester pregnancy. The success rate of termination for congenital abnormality and fetal demise was high. Vaginal misoprostol was an effective method for termination of second trimester pregnancy.

Thirty-six adult patients with 44 trigger fingers of less than four months' duration entered a prospective study on the efficiency of treatment with local injections of a combination of corticosteroids and lidocaine. From this study it may be concluded that the short-term success rate (93%) of one to three injections of methylprednisolone and lidocaine 2% (Depo-Medrol®) is comparable to that achieved by surgical or percutaneous tenolysis. At one year of follow-up, this success rate still amounted to 86%. In our hands, this therapy is without complications or side effects.

With the ever-growing Web, the Websites with objectionable contents like pornography, violence, racism, etc. have been augmented rapidly during recent years. Among the offensive contents, the pornography is the most harmful one affecting children safety and causing many destructive side effects. A content filter is one or more pieces of software that work together to prevent users from viewing material found on the Internet. This paper presents an efficient content based software system for detecting and filtering pornography images in Web pages. The proposed system runs online in the background of Internet Explorer (IE) for the purpose of restricting access to pornography Web pages. Skin and face detection techniques are the main components of the proposed system. Because the proposed filter works online, the authors propose two fasting techniques that can be used to speed up the filtering system. The results obtained using the proposed system is compared with four commercial filtering programs. The success rate of the proposed filtering system is better than the considered filtering programs.

<b><i>Introduction:</i></b> In France, performance of a termination of pregnancy is legally possible without any gestational age limit. After 22 weeks of gestation, a feticide is ethically performed using usually sufentanil and lidocaine. The aim of this study was to compare the use of remifentanil, a fast-acting morphine-derivating product, instead of sufentanil. <b><i>Methods:</i></b> This 2-center randomized, controlled, single-blinded phase-III treatment trial had 2 parallel arms: an experimental group using remifentanil with lidocaine versus a control group receiving sufentanil associated with lidocaine. This trial took place over a 40-month period. The primary outcome was time to fetal asystole after lidocaine injection. The secondary outcome measures were the procedure’s success rate, the rate of serious maternal side effects, and the presence of cellular or tissue modifications. <b><i>Results:</i></b> The study included 66 women, randomized into 2 groups of similar size and characteristics. Time to fetal asystole did not differ significantly between the groups, with a delay of 4 min (Q1−Q3, 2–11) in the sufentanil group and 4 min (Q1−Q3, 1–10) in the remifentanil group (<i>p</i> = 0.84). Similarly, the success rate of the procedure did not differ significantly. Fetal asystole was procured in &#x3c;2 min and persisted &#x3e;1 min for 16 (25.8%) women in our total population: 7 (22.5%) in the sufentanil group and 9 (29.0%) in the remifentanil group, <i>p</i> = 0.77. No severe maternal side effects were observed. Among the 49 fetopathological examinations performed, the few tissue and cell modifications observed did not cause any interpretation difficulties in either group. <b><i>Discussion/Conclusion:</i></b> Use of remifentanil instead of sufentanil for feticide procedure did not improve time to fetal asystole. No harmful effect was observed for either maternal tolerance or interpretation of the histologic slides.

Normal fertile women gives an oral dose of I-mu Ts'ao decoction (30 g. dry weight equivalent) showed an increase in intra-uterine pressure in 41.3% of 121 cases. The increase ranged from 150% to over 300% of spontaneous activity before dosing. A slightly higher success rate was observed with 2 successive doses or with improved experimental skill in later cases. Ergonovine (0.2 mg i.m.) scored a success rate of 61%. Therefore, I-mu Ts'ao decoction appeared to have a relative potency of 91% compared with ergonovine when the highest success rate (55.5%) of the former is considered. Blank control with water yield a positive response rate of 2.7%. There are no observable side-effects apart from diuresis.

A single-blind between-patient study in general practice was made to examine the acceptability and analgesic efficacy of a combination of fenoprofen (200 mg) and paracetamol (500 mg) given 3 to 4 times daily for a period of 4 to 14 days in the treatment of acute and chronic pain. The combination was compared with dihydrocodeine tartrate (30 mg) in two groups of 75 patients suffering from a wide variety of presenting conditions, including osteoarthritis, spondylitis, lumbago,' sciatica, non-articular rheumatism and trauma. Clinical and patient assessment indicated that the combination was an effective analgesic combination, significantly better in success rate than dihydrocodeine tartrate and with a much lower incidence of side-effects (13% of patients receiving fenoprofen and paracetamol reported side-effects compared to 37% for the dihydrocodeine group). The combination demonstrated particular success in the treatment of non-articular rheumatism.
