This research was an attempt to make it possible to provide nursing care and health education meet- ing the need not of care givers but of patients by identifying the nature of patients' self regulation experiences. The specific objective of this study was : 1) to explore self regulation experiences of patients with adult disease. The phenomenological approach in qualitative studies is used to serve this purpose. Colaizzi's method is used for the phenomenological analysis of the data in this study, which were collected from 25 patients hospitalized in the internal medical ward and oriental medical ward of a Seoul hospital, suffering from adult disease such as hypertension, arteriosclerosis and diabetes mellitus. The research was conducted over a period of March to September, 1994. The investigator conducted participated observations and in-depth unstructured interviews which were audiotaped under the permission of patients. The investigator read the data repeatedly to identify and categorize significant statements, formulating meanings, themes and theme clusters. The result is categorized as follows : Self regulation activities, their barriers and predisposing factors of a disease. Thirteen theme clusters of self regulation activities related to health identified were. “maintaining diet regimen”, “maintaining exercise regimen”, “maintaining medication regimen”, “maintaining oriental medical regimen”, “maintaining health monitoring regimen”, “maintaining self effort”, “maintaining religious life”, “maintaining social sup-port systems”, “maintaining peaceful mind”, “maintaining moderation in life”, “maintaining sincere attitude in life”, “maintaining natural life”, and “maintaining folk remedy” This findings confirm the fact that self regulation is complicatedly and diversely influenced by oriental medicine and folk remedy, and Korean traditional ideas melted in Confucianism, Buddhism, Taoism and Shamanism, and modern medical care and western culture. Seven theme clusters of self regulation barriers identified were : "lack of knowledge and self aware-ness", "lack of social supports", "lack of awareness of need in continuous regimen and treatment", "dissatisfaction with hospital and health care provider", "lack of self management ", "lack of will to combat illness", and "overconfidence in folk remedy" Four theme clusters of predisposing factors of a disease were : "cumulation of stressors", "fatalism", "careless life style", and "family history". In conclusion, this. study will prove helpful not only in understanding clients in light of our traditional culture but also in providing them with the kind of nursing care and health education satisfying their demands and particularly cultural needs.

The regulation of continuous and adjacent development was introduced to prevent unplanned and improper development and to protect environment in green zone and non-urban area that was deficient in infrastructure. Though it has been effective, it was repealed in 2011 by disorderly development problem caused by crafty tricks around restrictions. Alternatively, the Urban Planning Commission is now deliberating on the development permit, but there are still much to be resolved such as improper committee formation and abuse of power, insufficient green corridor preservation, a lack of use of planning information system, discordance between landscape management guidelines in laws, etc. Therefore, we suggest several ideas for improvement of development permit system as follows; intensive deliberation system in the Urban Planning Commission, integrated commission for green corridor prevention, early establishment of urban planning information system, making a development permission guideline to minimize discretional act of the Urban Planning Commission, etc.

When downloading files using an app or web-based application on the user's mobile phone, the path is set to be saved in the pre-defined default directory. Many applications requiring access to storage, including file managers, require a write or read permission of storage to provide numerous functions and services. This means that the application will have direct access to the download folder where the numerous files downloaded. In this paper, to prove our feasibility of attack using the security vulnerabilities mentioned above, we developed a file hacking function disguised as an encryption function in the file management application. The file that encrypted will be sent to hackers via E-mail simultaneously on the background. The developed application was evaluated from VirusTotal, a malicious analysis engine, was not detected as a malicious application in all 74 engines. Finally, in this paper, we propose a defense technique and an algorithm based on the Trusted Execution Environment (TEE) to supplement these storage vulnerabilities.

Objectives: Business operators handling hazardous chemicals regulated under the Chemical Substances Control Act (CSCA) must receive permits to operate their business from the Ministry of Environment. This study analyzed the status of recent legal violation in chemical handling workplaces in Ulsan where a large volume of chemicals is handled for industrial use. Methods: A total of 557 corporations have been granted legal status as business operators in Ulsan. For all business operators, legal violations in regard to the CSCA that were discovered by the environmental office in the last five years (2018~2022) were thoroughly analyzed. Results: A total of 225 violations of the CSCA have been discovered at 165 corporations, with the violation rate accounting for approximately 27% of all business operators. In particular, 22% of the 165 violators (36 corporations) were discovered to have violated twice or more, and some business operators (6%) even violated in consecutive years. Non-compliance of facility inspection was the most frequent violation (45 cases, 20.1%), followed by non-reporting of important changes in the permitted matters (23 cases, 10.3%), non-completion of legal safety education (19 cases, 8.5%), failure to secure permission for modification in the permitted matters (18 cases, 8.0%), and failure to submit chemical transport plans (16 cases, 7.1%). Conclusions: Most of the violations could have been prevented if the field personnel had paid sufficient attention. Thus, it is fundamentally necessary to create an environment for spontaneous safety management for themselves and to strengthen individual capabilities.

ID is used as identifying information and password as user authentication for ID-based authentication. In order to have a secure user authentication, the password is generated as a hash value on the client and sent to the server, where it is compared with the stored information and authentication is performed. However, if even one character is incorrect, the different hash value is generated, authentication will be failed and cannot be performed and various functions cannot be applied to the password. In this study, we generate several hash value including imaginary number of entered password and transmit to server and perform authentcation. we propose a technique can grants the right differentially to give various rights to the user who have many rights by one account. This can defend shoulder surfing attack by imaginary password and provide convenience to users who have various rights by granting right based on password.

Recently, according to the network environment, there are many researches for home network. Nowadays, in home network, the method that access control policy is managed for each home device by using ACL is popular, and EAM (Extranet access management) is applied as a solution. In addition, the research about secure OS is ongoing based on open operating system and the research of user authentication mechanisms for home network using home server is also in progress. However, these researches have some problems as follows; First, the transmission scope of expected access technology in home network is wide, so unauthenticated outside terminal can access the home network. Second, user is inconvenient because user need to set the necessary information for each device. Third, user privacy and convenience are not considered. OSGi provides a service platform for heterogeneous technologies in home network environment. Here, user access control is one of the core parts which should have no problems such as above items, but there are no concrete researches yet. Thus in this paper, we propose an access control policy management framework and access control operation based on RBAC for user access control in home network environment in which OSGi service platform is operated. First, we list the consideration which is not clearly mentioned in OSGi standard, and then we solve these above problems through new framework. In addition, we propose the effective and economical operation method which reduces the policy change frequency for user access control by using RBAC concept though limited resource of home gateway. Besides, in this paper, these proposed policies are defined separately as user-role assignment policy and permission-role assignment policy, and user decide their own policies. In conclusion, we provide the scheme to enhance the user convenience and to solve the privacy problem.

Security Act has been partially revised many times since it was revised to "Security Service Act". Main contents of such revision consist of the addition of security work such as protection or special security, responsibility enforcement of security company or security guard and systematic management of security service based on security work of previous security service act. But, it needs to be checked out that the fundamental matter about the concept of 'security' is directly related as double-edged sword in such flow of legal revision. That is because security service satisfies the multiple needs for security in the modern risky society and is based on the concept of active management whose goal is to forster and develop the function of actual security service comparing that current "Security Service Act" regulates the formal security service whose goal is permission of security service and systematic management based on article 2 as previous facilities and manned security that is guard duty-centered security service in another respect. So, this study pointed out the limit of interpreting security and security service in "Security Services Industry Act" in respect of providing private security service and drew the conclusion that the legislation and efforts are required for 'security for citizen' by reinterpreting the legislation and revision of private security service-related law as the normal regulation of "Security Services Industry Act" and the special law of "Private Security Services Industry Act".
