The purpose of this study was to generate a grounded theory of how families with kidney donor or recipient coped with kidney transplantations. Interview data from twelve families involved in kidney transplants was analyzed using the grounded theory method. Data analysis revealed that “protecting the family” was the main theme that represented family member experiences. In order to maintain family function and to protect the family from breaking up, family members had to adjust the family structure from the traditional style of a husband-centered family, to one that was patient health -centered. The process of this adjustment was a very long and difficult one, taking several years from the recognition of the kidney disease to the kidney transplants. Family members, especially spouses, employed nine different strategies to deal with various problems and conflicts which occurred during the process : 1) paying attention to the patient's illness and complications ; 2) accepting the patient's illness as the family's illness as well ; 3) managing the patient's illness and complications that occured ; 4) being thrifty ; 5)supporting the kidney donor ; 6) accepting and replacing the lost roles of the patient ; 7) keeping composure and encouraging the patient ; 8) sustaining the patient's independence ; 9) self-restraining sexual desires. These findings suggest that there is a developmental process where family members adjust to a kidney transplant over time. There is also a need for increased social and psychological health services for all family members over the course of kidney transplants.

This study intends to contribute to developing an effective marketing strategy targeting women in their 40's and 50's by classifying them into social classes and analyzing their wearing and purchasing behavior. The subject of this study are 344 women in their 40's and 50's living in Seoul, and the model sampling is done by allotment sampling. Modified survey based on references and former studies is used, and SAS package is used for analysis. The results of data analysis are as follows: 1. Women in their 40's and 50's are classified into 3 social classes, and the most influencial factor in the classification of social class is found to be total monthly income. 2 Clothing image of which each social class wear are proven to be significantly different among 3 classes. However, specific garment styles they wear are proven not to be significantly different. 3. Clothing purchasing behavior factors such as informants, clothing selection standards, store selection standards, place of purchase, shopping time, frequency of purchase, price of purchase, and paying methods are proven to be significantly different among 3 social classes. 4. Marketing strategies for each social class are provided based on these results.

This study is regards to merchandising in terms of paradigm shift on marketing and cost reduction. All research was done to trace the change of customer's purchasing trend taking examples through two of major women fashion brand, Katharine Hamnett and Cynthia Rowley since Korea has been in IMF controlling. The conclusion is as following; 1. After IMF controlling, young character casual and middle-low priced unisex mode have mainly been in '98 fashion trend. On item terms, cross coordination with reasonable prices was formed as main stream. 2. Shortened production lead-time made it possible to reduce its cost. Also new types of fashion business has been introduced to customers. 3. Speedy action are more emphasized through the benefits of simplified marketing channel and shortened payment terms. 4. It used to be a typical style to enjoy the high margin with an famous overseas brand paying license fee. Currently, the trend is extended to re-export to overseas for the licensed OEM goods.

In a situation where competition becomes intense, health care organizations constantly strive to provide more services with given personnel and time. While not only the 'quantity' of the services but also the 'quality' becomes increasingly important, various problems that can occur during the 'process' of service provision can be effectively managed by applying the methods of management science. In this study, we introduce the cases where the methods of management science can be applied for the management of health care organizations in Korea and abroad. There are many cases where various scenarios for improving the patients' accessibility to the services and for maximizing the efficient use of limited resources are established, and simulation or basic statistical analysis methods are used to solve the problems more systematically or to develop improvement plans. In this study, several exemplary cases, such as no-show of patients, crowding in the emergency room, prediction of the number of available beds in the intensive care units, nurse scheduling, delay of arrival of patients, and ordering of the proper amount of therapeutic materials, are introduced and discussed. From the perspective of administrators or clinicians, however, it may not be easy to master the methodology that requires considerable mathematical background or apply the theories to practice directly. Therefore, it is suggested that more practical and relatively simple analytical methods should be applied. Also, having a more positive attitude toward improving the current performance (e.g., a belief that 'we can always be better than now'), and paying attention to improving the job satisfaction by addressing problems, with experimental spirit and data-driven decision management.

As of late, people who enjoy fishing as a pastime in Korea has dramatically increased on the back of the increased national income and 5-day working system being in place. In the past, people used to fish in inland waters, but fishing on the sea has also shown a steady increase. The expanded fishing community along with increasing types of fishing, however, led to destruction of ecosystem by littering the waters of both inland and sea with wastes and reckless exploitation of fish resources. Fishing activities are usually taking place in inland waters, or on the sea, which is, by definition, a common property, and side effects such as free riding and diseconomy are frequently observed occurring. In other words, everyone can use the property free of charge(except paying fishing lot), and littering the waters with pollutants and wastes stemming from fishing activities is currently rampant. In this context, this paper studies the necessity of introducing fishing license system and its feasibility in Korea from a perspective to improve the national welfare through policy measures based on 'polluter pays principle' to prevent further environmental pollution in the fishing lot and preserve fishery resources. Study shows that introduction of Recreational fishing license system is urgently needed, but it is concluded that it should take more time to implement the system so as to accomodate the differing interests of all parties involved including recreational fishing industry, while strengthening public relation activities to solicit for the people's understanding of the system to be introduced.

Cloud is the latest buzz word in the internet community among developers, consumers and security researchers. There have been many attacks on the cloud in the recent past where the services got interrupted and consumer privacy has been compromised. Denial of Service (DoS) attacks effect the service availability to the genuine user. Customers are paying to use the cloud, so enhancing the availability of services is a paramount task for the service provider. In the presence of DoS attacks, the availability is reduced drastically. Such attacks must be detected and prevented as early as possible and the power of computational approaches can be used to do so. In the literature, machine learning techniques have been used to detect the presence of attacks. In this paper, a novel approach is proposed, where intelligent rule based feature selection and classification are performed for DoS attack detection in the cloud. The performance of the proposed system has been evaluated on an experimental cloud set up with real time DoS tools. It was observed that the proposed system achieved an accuracy of 98.46% on the experimental data for 10,000 instances with 10 fold cross-validation. By using this methodology, the service providers will be able to provide a more secure cloud environment to the customers.

This study aims to investigate national image of South Korea held by russians. Surveys(based on Free-association Image) and discussion were conducted on LiveJournal (internet blog) with russian netizen. A national image is influenced by a subjective perspective rather than an objective one. Therefore, an image can differ substantially from reality. Futhermore, it takes a long time to change an established image, particularly to a positive image. According to the results, the image of South Korea were dominated by unstable political situations, especially factors related to North Korea. In addition, based on Free-association image, thinking about Korea or Korean, most russians recognize Korea(South) with North Korea. Above all Russians recognize Korea, basing their images on factor of the past or their neighbors-russian korean- or famous Korean brand like Samsung, LG, Hyndai, "Dosirak". Russian netizen did not recognize South Korea as one of leading countries in Asia, paying little attention to South Korea compared to China or Japan. We belive that it is necessary to consider these situations in future efforts to enhance the national image of South Korea.

Governments around the world are actively establishing strategies and initiatives to spread the use of artificial intelligence (AI), for AI is not a mere new technology, but is an innovative technology that brings about extensive changes in industrial and social structures and is a core engine that will lead the 4th Industrial Revolution. The South Korean government has also been paying attention to AI as a technology and tool for innovative growth, but its application to the industries is still rather sluggish. The government has prepared multifarious AI-related policies with the aim of constructing South Korea as an AI powerhouse, but there is no clear strategy on which detailed policies to implement first and which industries to apply AI preferentially. With these limitations of South Korea's AI policies in mind, this paper analyzed the priorities of industries in AI adoption and the priorities of AI-related national policies, using Delphi-AHP method for 30 top-level AI experts in South Korea. The results of analysis show that AI application is urgent and necessary in the fields of medical/healthcare, public and safety, and manufacturing, which seems to reflect the peak of the COVID-19 crisis in the second half of 2020 at the time of the investigation. And it turns out that policies related to AI talent cultivation, data, and R&D investment are important and urgent above all in order for organizations to apply AI. This suggests that strategies are required to focus limited national resources on these industries and policies first.

In recently years, there are cyber-weapon aim to national infrastructure such as 'stuxnet'. Security experts of the world are paying attention to this phenomenon. The networks which controls traffic, subway, waterworks of the city are safe from threats such as computer virus, malware, because the networks were built on closed-networks. However, it's about time to develop countermeasure for the cyber-weapon. In this paper, we review status-quo of the control systems for metropolitan infrastructure and analyze the risk of industrial control system in SCADA(Supervisory Control And Data Acquisition) network. Finally, we propose a security model for control systems of metropolitan infrastructure.

Recently, many manufacturing companies are paying more attention to energy efficiency due to increased energy costs. Energy-efficient scheduling of production systems is a good method for energy efficiency improvement and cost reduction. In this research, we assumed the tire production problem and aim to construct a production scheduling considering specific shape module types, ordered amount for each tire, number of production modules, and the production time for each type. To facilitate effective production scheduling, we considered the types and number of shape modules currently available, and tire types that can be selected to be produced in the next stage were used as additional inputs, In addition to that, additional production was permitted to reduce the halt of production processing. Thus, an average production module utilization rate of about 62 percent was obtained.
