The proportion of digital evidence in criminal cases has increased, while at the same time, the spread of the Internet has made it easy to delete information that is stored in another place and thus, the Internet is being used to delete online criminal evidence. To respond quickly and effectively to cybercrime, 29 countries signed the Convention on Cybercrime in 2001 through the Council of Europe. Article 16 of the Convention relates to the expedited preservation of stored computer data and requires signatories to adopt legislative measures to enable its competent authorities to order expeditious preservation of specified computer data where there are grounds to believe that the data is particularly vulnerable to loss or modification. More than 60 countries have joined the Convention since 2001 and have made efforts to improve their legal system in line with it. The United States legislated 18 U.S.C. § 2703(f) to preserve electronic evidence pending the issuance of a court order. The German Code of Criminal Procedure §§ 94~95 allows prosecution authorities to seize evidence or issue production orders without court control in urgent circumstances. A custodian shall be obliged to surrender evidence upon a request that evidence be preserved, and non-compliance results in punishment. Japan legislated the Criminal Procedure Act § 197(3) and (4) to establish a legal base for requesting that electronic records that are stored by an ISP not be deleted. The Korean Criminal Procedure Act § 184 outlines procedures for the preservation of evidence but does not adequately address the expeditious preservation of digital evidence that may be vulnerable to deletion. This paper analyzes nine considerations, including request subjects, requirements, and cost reimbursement to establish directions to improve the legal system for the expedited preservation of digital evidence. A new method to preserve online digital evidence in urgent cases is necessary.

Background: An increasing trend of cytotoxic drug use, mainly in cancer treatment, has increased the occupational exposure among the nurses. This study aimed to assess the change of nurses' safety-related knowledge as well as attitude levels and subsequently to assess the change of cytotoxic drug handling practices in wards after a series of pharmacist-based interventions. Materials and Methods: This prospective interventional study with a before and after design requested a single group of 96 nurses in 15 wards actively providing chemotherapy to answer a self-administered questionnaire. A performance checklist was then used to determine the compliance of all these wards with the recommended safety measures. The first and second assessments took 2 months respectively with a 9-month intervention period. Pharmacist-based interventions included a series of technical, educational and administrative support measures consisting of the initiation of closed-system cytotoxic drug reconstitution (CDR) services, courses, training workshops and guideline updates. Results: The mean age of nurses was $32.2{\pm}6.19$ years. Most of them were female (93.8%) and married (72.9%). The mean knowledge score of nurses was significantly increased from $45.5{\pm}10.52$ to $73.4{\pm}8.88$ out of 100 (p<0.001) at the end of the second assessment. Overall, the mean practice score among the wards was improved from $7.6{\pm}5.51$ to $15.3{\pm}2.55$ out of 20 (p<0.001). Conclusions: The pharmacist-based interventions improved the knowledge, attitude and safe practices of nurses in cytotoxic drug handling. Further assessment may help to confirm the sustainability of the improved practices.

Early diagnosis has a major role in improving prognosis of breast cancer. The purpose of this study was to assess the risk status of women 35-69 years of age using risk assessment models and the prevalence of mammography in a community setting. The sample of this cross sectional study consisted of 227 women, 35-69 years of age residing in Izmir, a city located in western region of Turkey. A questionnaire was used to collect data and the Gail and Cuzick-Tyrer models were applied to assess the risk of breast cancer. In this study, 52.7% of women had mammography at least once, and 41.3% of the women over the age of 40 had mammography screening in the last two years. The five years risk for breast cancer was high in 15.8% of women according to the Gail model and ten years risk was high in 21.7% with the Cuzick-Tyrer model. In the present study, the breast cancer risk levels were assessed in a population setting for the first time in Turkey using breast cancer risk level assessment models. Being in 60-69 age group, having low education and not being in menopause were significant risk factors for not having mammography according to logistic regression analysis. Mammography utilization rate was low. Women must be educated about breast cancer screening methods and early diagnosis. The women in the high risk group should be informed on their risk status which may increase their attendance at breast cancer screening.

Previous experimental and clinical investigations suggest a possible role of new nootropic drug, oxiracetam, in improving cognitive performances in patients affected by organic brain syndrome. In this study, the cognitive and behavioral effects of oxiracetam treatment in patients with clinical symptoms of organic brain syndrome were evaluated. Sixty-six patients were enrolled and assigned to either oxiracetam or placebo, according to a randomized, double-blind design between two patient-groups. Either oxiracetam or placebo was orally given bid for 8 weeks ; daily dose of oxiracetam was 1600mg. All the patients, enrolled in this study, were diagnosed as having mild to moderate cognitive dysfunction as defined by a baseline Mini Mental State ExaminationKorean version (MMSE-K) score between 14 and 25. The patients under-went, at baseline, 4 weeks and 8 weeks after, routine laboratory study (CBC, SMA12, U/A, EKG) and the following neuropsychological tests ; MMSE-K, modified Korean Wechsler Intelligence Scale(MKWIS), Nurses' Observation Scale for Geriatric patients(NOSGER). Fifteen patients of whom were dropped out or excluded from the analysis because of poor compliance or violation of the protocol. Fiftyone patients (aged 54~78 years, male 25, female 26) were analyzed (vascular dementia, 30 ; senile dementia of Alzheimer type, 9 ; mixed type, 5 ; other cause, 7). Statistical analysis of the data demonstrated that the two groups were comparable at baseline. At the end of each study period the oxiracetam group scored significantly better on the majority of the tests evaluating cognitive function, psychometricity and the improvement rating scale of subjective symptoms than placebo group, in which worsening trends or no changes were seen on the whole. No side effects were noted during oxiracetam treatment. The present study, showing positive clinical findings after oxiracetam therapy, confirmed that this drug can be useful pharmacological treatment in organic brain syndrome.

Purpose: The purpose of this survey was to assess the satisfaction of patients suffering from musculoskeletal pain with physical therapy (PT) in Busan, Daegu, and Kyeongsang provinces using a Korean-language version of the patient satisfaction questionnaire with physical therapy service (PSPT). Methods: A total of 654 patients, having PT for their musculoskeletal pains, participated. Consenting subjects completed a 20-item PSPT on their $6^{th}$ or last treatment day. Simple descriptive statistics were used for respondent characteristics, and mean of satisfaction score in each item. Regression analysis was performed on each item of the questionnaire. Results: 654 subjects responded during or after their PT services. 297 (45.5%) of them were male and the most common site of pain was the spine. The mean of each item score (1-5) ranged from 2.14 for "my therapist did not listen to my concerns" to 4.12 for "my therapist treated me respectfully". Receptionist's attitude, registration process, service time of the hospital, and answer to the patient's questions greatly affected the general satisfaction of the respondents. Conclusion: The results showed high levels of satisfaction to the general process for obtaining treatment as well as the therapist's attitudes toward their patients. They may provide valuable patients' feedback regarding PT service for musculoskeletal pain. Therefore, it may be used by physical therapists to improve future patient experiences with a view to improving the patient's attendance and compliance with the PT service protocols for patients suffering from musculoskeletal pain.

This study is about an arrangement method of trapezoidal pre-cast segment lining that can be applied in shield tunnel construction. Trapezoidal segment lining is formed by assembling tapered pre-cast concrete segments taking advantage of the tapered shape of pre-cast segments upon delivery on site. By calculating tapering of the segments manufactured in single type and rotating the segments when putting them together, a variety of tunnel alignments can be arranged in the most efficient way. Once the design criteria and tunnel alignment (straight or curved) is analyzed, the sequence of assembling trapezoidal segments in compliance with tunnel alignment will be computed. On site an operator can utilize the softwareto automatically determine sequential arrangement of trapezoidal segments. When the actual arrangement of segmental lining is different from the computed output, the operator can input the actually measured values to coincide the computerized calculation with the real status of assembly. Then the adjustment will be the basis of subsequent arrangement of segments, thus the continuity of work can be guaranteed.

The purpose of this paper is to propose the modeling of multiagent based SCM and implement the prototype in the Internet environment. SCM process follows the supply chain operations reference (SCOR) model which has been suggested by Supply Chain Counsil. SCOR model has been positioned to become the industry standard for describing and improving operational process in SCM. Five basic processes, plan, source, matte, deliver and return are defined in the SCOR model, through which a company establishes its supply chain competitive objectives. A supply chain is a world wide network of suppliers, factories, warehouses, distribution centers and retailers through which raw materials are acquired, transformed or manufactured and delivered to customers by autonomous or semiautonomous process. With the pressure from the higher standard of customer compliance, a frequent model change, product complexity and globalization, the combination of supply chain process with an advanced infrastructure in terms of multiagent systems have been highly required. Since SCM is fundamentally concerned with coherence among multiple decision makers, a multiagent framework based on explicit communication between constituent agents such as suppliers, manufacturers, and distributors is a natural choice. Multiagent framework is defined to perform different activities within a supply chain. Dynamic and changing functions of supply chain can be dealt with multi-agent by cooperating with other agents. In the areas of inventory management, remote diagnostics, communications with field workers, order fulfillment including tracking and monitoring, stock visibility, real-time shop floor data collection, asset tracking and warehousing, customer-centric supply chain can be applied and implemented utilizing multiagent. In this paper, for the order processing event between the buyer and seller relationship, multiagent were defined corresponding to the SCOR process. A prototype system was developed and implemented on the actual TCP/IP environment for the purchase order processing event. The implementation result assures that multiagent based SCM enhances the speed, visibility, proactiveness and responsiveness of activities in the supply chain.

Drug delivery technologies are patent protected formulation technologies that modify drug release profile, absorption, distribution, and elimination for the benefit of improving product efficacy and safety, as well as patient convenience and compliance. The most commonly used transdermal system is the skin patch using various types of technologies. Compared with other method of dosage, it is possible to use for a long term. It is also possible to stop the drug dosage are stop if the drug dosage lead to side effect. Polysaccharide, such as karaya gum and locust bean gum(LBG)/water-soluble chitosan oligomer(WSCO) were selected as base materials of TDS. Also, these polymers were characterized in terms of enhancers, tacrine contents. Among these polysaccharide, the permeation rate of karaya gum matrix was fastest in tacrine such as lipophilic drug in vitro. We used glycerin, PEG 400, and PEG 800 as enhancers. Therefore, transdermal absorption of tacrine could be improved by changing vehicle composition or by using penetration enhancers. Especially it would be anticipated that the high permeation efficacy could be obtained by using vehicle that has enhancing effect for itself and by adding enhancers to it.
