Purpose: Expecting a new system of nursing security for elderly in operation in 2007, a substantial expansion of nursing facilities for elderly and quality management of those facilities are imperative now. Therefore. specific quality management measures or schemes which could be used for the operation of small-scale nursing homes are in urgent need. The purpose of this study was to develop a Quality Management Index(QMI) to guide Nursing Home management. Method: This study developed a QMI for small-scale nursing homes, which focused on quality management in structural dimensions such as environment, staffs, local community network, atmosphere, and quality management in process dimensions such as nursing, communication, resident satisfaction. The QMI developed in this study is based on extensive review of literature and the actual experiences of nursing home operation. It consists of 7 dimensions, 39 components and 148 indexes, which have been verified by three times validity tests of experts group. Then the QMI was used to evaluate the quality management levels of nursing homes in Korea. Result: In sum, after analyzing all nursing homes in Korea operated by nurses, this study found that there were significant differences of quality management level among facilities in several dimensions such as environment, staffs, local community connections, communication. In dimensions such as nursing, atmosphere, resident satisfaction, however, little differences of quality management level among facilities were reported. It is considered that this result has to do with several factors like the size of facilities, operation expenses, operation forms, the disposition of professional human resources, and philosophy and management policy of the owners. As far as generalization is concerned, however, it needs to be noted here that the sample size for this study is not statistically big enough to generalize the results. Conclusion: Having Developed a QMI for small-scale nursing home with 7 dimensions, 39 components and 148 indexes, this study is expected to be used in developing more elaborated quality evaluation tools for nursing homes, and also function as a practical guide of quality management for those who are opening and managing nursing homes. I hope this quality index could lead to further development of a standardized quality management index, and eventually contribute to quality improvement of nursing homes.

We present the motivation, design and implementation of a smart home system in Korea. Our system is open, extensible, integrated, intelligent, and usage-centric. We detail the challenges and key design requirements for the smart home system based on our past experiences, and show how convergence system design is a capable methodology for enabling an integrated and multi-faceted home management system that encompasses energy management, home appliance control, environment management, u-health, and living support functionalities under a single unified design. Using energy management as a specific case study, we demonstrate how convergence system design can encapsulate technology heterogeneity and hardware-software disparity without compromising simple yet powerful user interfaces.

In this study, the various financial management systems practiced by modem dual-income families were assessed by in-depth interviews with 6 people, 3 practicing integrated financial management and 3 practicing individual financial management. The results indicated significant differences between the two financial management methods regarding family structure, individual values, and family finances. Families that practiced individual financial management consisted of weekend couples without children who showed an individual-centered value tendency and seemed to take a positive attitude towards their future economic situation due to possession of their on stabilized financial assets. Based on these results, we can expect more families to adopt methods of individual financial management and show a wider variety in their financial planning tools which will require adequate and efficient countermeasures and strategies suitable for each financial management practice.

It seems high time to increase productivity by adopting e-business to overcome challenges posed by both external factors including the appreciation of Korean won, oil hikes and fierce global competition and domestic issues represented by disparities between large corporations and small and medium enterprises (SMEs), Seoul metropolitan and local cities, and export and domestic demand all of which weaken future growth engines in the Korean economy. The demands of the globalization era are for innovative changes in businessprocess and industrial structure aiming for creating new values. To this end, e-business is expected to play a core role in the sophistication of the Korean economy through new values and innovation. In order to examine business performance in e-business-adopting industries, this study analyzed the home shopping industry by closely looking into the financial ratios including the ratio of net profit to sales, the ratio of operation income to sales, the ratio of gross cost to sales cost, the ratio of gross cost to selling, general and administrative (SG&A) expense, and return of investment (ROI). This study, for best outcome, referred to corporate financial statements as a main resource to calculate financial ratios by utilizing Data Analysis, Retrieval and Transfer System (DART) of the Financial Supervisory Service, one of the Korea's financial supervisory authorities. First of all, the result of the trend analysis on the ratio of net profit to sales is as following. CJ Home Shopping has registered a remarkable increase in its ratio of net profit rate to sales since 2002 while its competitors find it hard to catch up with CJ's stunning performances. This is partly due to the efficient management compared to CJ's value of capital. Such significance, if the current trend continues, will make the front-runner assume the largest market share. On the other hand, GS Home Shopping, despite its best organized system and largest value of capital among others, lacks efficiency in management. Second of all, the result of the trend analysis on the ratio of operation income to sales is as following. Both CJ Home Shopping and GS Home Shopping have, until 2004, recorded similar growth trend. However, while CJ Home Shopping's operating income continued to increase in 2005, GS Home Shopping observed its operating income declining which resulted in the increasing income gap with CJ Home Shopping. While CJ Home Shopping with the largest market share in home shopping industryis engaged in aggressive marketing, GS Home Shopping due to its stability-driven management strategies falls behind CJ again in the ratio of operation income to sales in spite of its favorable management environment including its large capital. Companies in the Group B were established in the same year of 2001. NS Home Shopping was the first in the Group B to shift its loss to profit. Woori Home Shopping has continued to post operating loss for three consecutive years and finally was sold to Lotte Group in 2007, but since then, has registered a continuing increase in net income on sales. Third of all, the result of the trend analysis on the ratio of gross cost to sales cost is as following. Since home shopping falls into sales business, its cost of sales is much lower than that of other types of business such as manufacturing industry. Since 2002 in gross costs including cost of sales, SG&A expense, and non-operating expense, cost of sales turned out to have remarkably decreased. Group B has also posted a notable decline in the same sector since 2002. Fourth of all, the result of the trend analysis on the ratio of gross cost to SG&A expense is as following. Due to its unique characteristics, the home shopping industry usually posts ahigh ratio of SG&A expense. However, more than 80% of SG&A expense means the result of lax management and at the same time, a sharp lower net income on sales than other industries. Last but not least, the result of the trend analysis on ROI is as following. As for CJ Home Shopping, the curve of ROI looks similar to that of its investment on fixed assets. As it turned out, the company's ratio of fixed assets to operating income skyrocketed in 2004 and 2005. As far as GS Home Shopping is concerned, its fixed assets are not as much as that of CJ Home Shopping. Consequently, competition in the home shopping industry, at the moment, is among CJ, GS, Hyundai, NS and Woori Home Shoppings, and all of them need to more thoroughly manage their costs. In order for the late-comers of Group B and other home shopping companies to advance further, the current lax management should be reformed particularly on their SG&A expense sector. Provided that the total sales volume in the Internet shopping sector is projected to grow over 20 trillion won by the year 2010, it is concluded that all the participants in the home shopping industry should put strategies on efficient management on costs and expenses as their top priority rather than increase revenues, if they hope to grow even further after 2007.
