A local storage of HTML5 is a Web Storage, which is stored permanently on a local computer in the form of files. The contents of the storage can be easily accessed and modified because it is stored as plaintext. Moreover, because the internet browser classifies the local storages of each domain using file names, the malicious attacker can abuse victim's local storage files by changing file names. In the paper, we propose a scheme to maintain the integrity and the confidentiality of the local storage's source domain and source device. The key idea is that the client encrypts the data stored in the local storage with cipher key, which is managed by the web server. On the step of requesting the cipher key, the web server authenticates whether the client is legal source of local storage or not. Finally, we showed that our method can detect an abnormal access to the local storage through experiments according to the proposed method.

When conducting CTOD test, especially in thick welded steel plate, fatigue pre-cracking occasionally failed to satisfy the requirements of standards thus making the test result invalid. Internally accumulated residual stress of test piece has been thought as one of the main reasons. The propagation of fatigue crack, started from the tip of machined notch, which might have propagated irregularly due to residual stress field. To overcome this kind of difficulty three methods to modify the residual stress are suggested in standard i.e. local compression, reverse bending and stepwise high-R ratio method. In this paper not only multi pass welding but also local pre-compressing process of thick steel plate has been simulated using finite element method for clarifying variation of internal welding residual stress. The simulated results show that welding residual stress is compressive in the middle section of the model and it is predominantly increased after machining the specimen. Comparing as-welded state all component of the welding residual stress changing to compressive in the tip of machine notch whereas residual stress of the outer area remain as tensile condition relatively. Analysis results also show that this irregular residual stress distribution is improved to be more uniformly by applying local compression.

Objectives: To assess the current public participation in-local health policy and its implications through the analysis of policy networks in health center programs. Methods: We examined the decision-making process in sub-health center installations and the implementation process in metabolic syndrome management program cases in two districts ('gu's) of Seoul. Participants of the policy network were selected by the snowballing method and completed self-administered questionnaires. Actors, the interactions among actors, and the characteristics of the network were analyzed by Netminer. Results: The results showed that the public is not yet actively participating in the local public health policy processes of decision-making and implementation. In the decision-making process, most of the network actors were in the public sector, while the private sector was a minor actor and participated in only a limited number of issues after the major decisions were made. In the implementation process, the program was led by the health center, while other actors participated passively. Conclusions: Public participation in Korean public health policy is not yet well activated. Preliminary discussions with various stakeholders, including civil society, are needed before making important local public health policy decisions. In addition, efforts to include local institutions and residents in the implementation process with the public officials are necessary to improve the situation.

Text mining is one of the big data analysis methods that extracts meaningful information from atypical large-scale text data. In this study, text mining was used to monitor citizens' opinions on the policies and systems being implemented. We collected 5,108 newspaper articles and 748 online cafe posts related to 'Gyeonggi Lacal Currency' and performed frequency analysis, TF-IDF analysis, association analysis, and word tree visualization analysis. As a result, many articles related to the purpose of introducing local currency, the benefits provided, and the method of use. However, the contents related to the actual use of local currency were written in the online cafe posts. In order to revitalize local currency, the news was involved in the promotion of local currency as an informant. Online cafe posts consisted of the opinions of citizens who are local currency users. SNS and text mining are expected to effectively activate various policies as well as local currency.

Background/Aims: Improved knowledge of local epidemiology and predicting risk factors of multidrug-resistant (MDR) bacteria are required to optimize the management of infections. This study examined local epidemiology and antibiotic resistance patterns of liver cirrhosis (LC) patients and evaluated the predictors of MDR bacteremia in Korea. Methods: This was a retrospective study including 140 LC patients diagnosed with bacteremia between January 2017 and December 2022. Local epidemiology and antibiotic resistance patterns and the determinants of MDR bacteremia were analyzed using logistic regression analysis. Results: The most frequently isolated bacteria, from the bloodstream, were Escherichia coli (n = 45, 31.7%) and Klebsiella spp. (n = 35, 24.6%). Thirty-four isolates (23.9%) were MDR, and extended-spectrum beta-lactamase E. coli (52.9%) and methicillin-resistant Staphylococcus aureus (17.6%) were the most commonly isolated MDR bacteria. When Enterococcus spp. were cultured, the majority were MDR (MDR 83.3% vs. 16.7%, p = 0.003), particularly vancomycin-susceptible Enterococcus faecium. Antibiotics administration within 30 days and/or nosocomial infection was a significant predictor of MDR bacteremia (OR: 3.40, 95% CI: 1.24-9.27, p = 0.02). MDR bacteremia was not predicted by sepsis predictors, such as positive systemic inflammatory response syndrome (SIRS) or quick Sequential Organ Failure Assessment (qSOFA). Conclusions: More than 70% of strains that can be treated with a third-generation cephalosporin have been cultured. In cirrhotic patients, antibiotic administration within 30 days and/or nosocomial infection are predictors of MDR bacteremia; therefore, empirical administration of broad-spectrum antibiotics should be considered when these risk factors are present.

In this paper, we consider a conjecture of I. N. Herstein for local commutators of symmetric elements and unitary elements of division rings. For example, we show that if D is a finite dimensional division ring with involution ${\star}$ and if $a{\in}D^*=D{\setminus}\{0\}$ such that local commutators $axa^{-1}x^{-1}$ at a are radical over the center F of D for every $x{\in}D^*$ with $x^{\star}=x$, then either $a{\in}F$ or ${\dim}_F\;D=4$.

The purpose of this study is to evaluate the community based home care service, and make reorientation for better service. The data was collected from the public health center, which was operated for one year, 1997. This case is evaluated and reoriented according to five elements of public health care system; system of resources for public health, organization and administration, health care delivery system of financing, management. In resources for public health, available health personnels are 15 physicians, 17 nurses, 11 nurse aides and 2 other persons. One professional health personnel take care of 609 clients, The equipments used for elderly and the disabled are 6 wheelchairs, 4 walkers, 1 hairwashers and 30 viberations. But these equipments are not enough to deal all clients. In organization and administration, planning and setting goals for community home care are made by the director, supervisor of family department and public health nurse. So there is no regular commitee for home care services in this community. The form of delivery of health care is focused on preventive health care. The important works of public health nurse are health education, preventive care for hypertension, D.M. and vaccination of communicable desease. In finaning system, funds come from central government(8.3%), local goverment(16.7%) and health center itself(3.8%), The services consist of health education, vaccination, clinical test and equipment. There are several local volunteers, which are local hospitals, a college, a christian association, a catholic association, a drivers association and a disabled association. The volunteer groups give physical and mental support to the clients. In management, this health center has three evaluation methods. One is done by local government, one is done by health center itself, and the other is done by clients with questionair. But the evaluation tools are deferent between agency. Home care services must be planned and evaluated. This public health center has to have more personnel, equipments, education for professional kowledge and meetings with community volunteer agencies.

The public health service center and its branch are, as one of public institution, responsible for providing non-profitable medical service to local residents, which can't be addressed by private medical institutes. In addition, as a planning coordinator, they need to manage local medical resources effectively to make sure local residents can be offered good-quality health service fairly and impartially. The purpose of this study was to highlight the importance of physical therapy in public health service center's successful role performance, one of treatment to which local residents had a direct access. For attaining the purpose, an investigation was made into the actual facilities of public health service center and its branches in North Cholla province, the extent of use of physicaltherapy room, and the general characteristics of physical therapists. And literatures concerned were referred to. As a result, the dominant opinion was that the current physicaltherapy room shoulder be more reinforced(38.9%) or that it should he kept as it was(46.5%). Besides, the physical therapists investigated still were serving in a poor working condition. To elevate the quality and quantity of medical service, the current way to employ expert personnels temporarily or not to guarantee the position of physiotherapists should be removed immediately. Instead, physicaltherapists should be employed as regular public official. As, in home-visit project, physiotherapist are expected to play a bigger role in rehabilitation care or the management of patients with chronic disease, the physicaltherapy room should be increased and more physicaltherapists should be provided to health service institutions.

Objectives: Yearly, annual report of cancer patients in Korea is released by National Cancer Center. But, this report is focused in all of the patients in nation. So, there is needed to modify and analyze this report to be used properly for local resident. In Ulleung island, local county and Ulleung medical center don't have cancer occurrence data of local resident until now. The aim of this analysis is to know characteristics and data of cancer patients occurrence in Ulleung island for 10 years. Methods: We are offered data of cancer patients occurrence in Ulleung island for 10 years from National Cancer Center. This data was composed of sex, address (only town level), diagnosed date, diagnosis. So, we analyze this data and compare to Korea data for same duration. Results: There were 268 patients for 10 years (1993-2002). Man were 175 about 65% and women were 93 about 35%. There were 163 in Ulleungeup about 60%, 39 in Seomyun about 14.5% and 48 in Bukmyun about 18%. There were 19 patients in unknown residence. After 1998, above 30 patients were occurred, but before 1998, below 27 patients were occurred. Diagnosed date was concentrated in June, 33 patients were occurred about 12%, but least occurred month was December. Most occurred age were from 60 to 69, there were 80 patients about 30%. Most occurred cancer was gastric cancer, there were 54 patients about 20%. Hepatic cancer was second and third was lung cancer. In man, most occurred cancers were gastric cancer and hepatic cancer, both was 38 patients. In woman, gastric cancer and uterine cervix cancer were occurred mostly. After 2001, in Korea most occurred female cancer was breast, but in Ulleung island, most occurred cancer was stomach. Conclusions: Researcher should demand and analyze cancer data from National Cancer Center that cancer management project in local county and public health education of cancer could focus on local resident because annually released cancer data from National Cancer Center focus on a nation. In Ulleung island, cancer incidence was more than incidence in Korea and breast cancer was occurred less than in Korea. So, more study should be needed to confirm why more cancer were occurred than Korea and breast cancer was less occurred.
