The purpose of this paper is to first of all analyse the trend of international National Defense Expense of 30 OECD member states and compare it with that of Korea in order to predict an appropriate level of National Defence Expense. As a result of the research, Korea's National Defense Expense has been exploited at 'considerably low level', hence restore its increasing expense rate from 3.87% in 2009 and 5.8% in 2010 to somewhat higher rate, so as to maintain stable supply and demand of National Defense Expense. The reason to the increase of National Defense Expense is to most importantly ensure 'appropriate amount suitable for its national status' and also that National Defense Expense takes up crucial part for protection of not only life and assets of a people but also of national viability.

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.

This study is designed to understand purchase motivation for garment depending on demographic factors among college students in Yanbian, China. Questionnaire was used for measurement tools to study the subject of the thesis. The main study was conducted against 450 college students from May 17 to June 5, 2001. The data for the study were analyzed using SAS PC program for frequency distribution, percentage, t -test, and one way ANOVA. The purchase motivation for garment are affected by demographic factors such as gender, average monthly household income, monthly expense for clothing. The result was showed as follows: A meaningful difference showed in 3 areas 'to try a new trend, impulsive buying at the store display, discount advertising' depending on the gender in terms of purchase motivations, and in all the three areas, male students showed a higher ranking. But in other motivation areas, no difference was noticed in terms of gender. In terms of purchase motivation based on monthly income, only one area 'impulse buying from a store display' showed a meaningful difference. Respondents with an average monthly household income above 2,000 yuan showed a higher tendency of 'impulse buying' compared to those with below 500 yuan or those with between 500-2,000yuan. Those with the average monthly household income below 500 yuan showed the lowest ranking in the impulse buying. In other areas of purchase motivation, average monthly household income was not an important element. A meaningful difference showed in 4 areas, 'to try a new trend, impulse buying from a store display, discount advertising', and 'for a change of mood' in the product motivation based on expense on clothing. Respondents with an average monthly expense for clothing above 100 yuan showed a higher ranking in all 4 areas than those with less than 100 yuan. In other areas, the average monthly clothing expense didn't give any impact.

Urben wage workers' education expenditure among different social classes from 1979 to 1993 has been compared. Eduction expenditure has increased much more than that of income resulting from income increase and government policy. Education expenditure gaps among social classes have showed to be an increasing trend although the ratio of education expense to the income has increased among low class families. Average income elasticity was 1.1 and this result showed that education expense was luxury good. Income elasticity of education expense among low class families have fluctuated more than any other classes resulting from construction business cycle and housing rent increase. Average Gini coefficient was 0.38 and turned out to be highest among 9 household expenditures, however it was in the trend of improvement from 81. But from 91 Gini Coefficient went up high again. Main reason for this increase was due to high social class families' eucation expenditure increase. Government's strong policies to enhance equality level of education opportunity and to support low class families are urged.

National water supply, water resources available, the ratio of water supply to total water resources, and the ratio of water supply to available water resources were investigated to find global seawater desalination plant market for 163 nations. Water resources available per capita from 2007 to 2016, population in water scarcity region from 2011 to 2016, and the ratio of water scarcity population to total population were also analyzed for the countries. Annual percentage increase in total municipal drinking water capital expenditure and Annual percentage increase in total industrial water market were analyzed to predict the amount of water supply by use. 76 countries are suffering from water scarcity and 60 countries among the countries have coastal regions. Forty countries were selected by considering the considerable amount and highly increasing trend of water demand by use. Most countries show increasing trend of industrial water and 82 countries have more than 4% annual increasing rate for domestic water expense from 2008 to 2016 among 163 countries. Among the 76 water scarcity countries 16 countries were finally selected by considering expense prediction by use. Middle-east, east asia, pacific ocean, and west europe regions include most selected countries.

Purpose : Many studies showed that having a usual source of care improved the efficient access of healthcare service. However in Korea there have been few studies on the usual source of care. So this study aims to find whether having a usual source of care affect the medical utilization and expense. Methodology/Approach : We used the Korean Health Panel data in 2012, 2013 to examine the change of utilization and expenses in ambulatory care affected by having a usual source of care. We selected 1,215 hypertension patients without usual source of care in 2012 and performed linear regression analysis to identify the difference between treatment group(with usual source of care in 2013) and control group(without usual source of care in 2013). Then we performed analysis again separated by the age group. Findings : Among study population, 711(58.5%) reported that they have a usual source of care in 2013. Treatment group reported 1.85 less increase in outpatient visits and 69,234 won less increase in expense than control group with weak significance(visit ${\beta}$ -1.85 p-value 0.0807, expense ${\beta}$ -69,234 p-value 0.0541). People under the age of 65 showed significant change in outpatient visits for tertiary hospital (visit ${\beta}$ -0.78 p-value 0.0154, expense ${\beta}$ -91,462 p-value 0.0168). The analysis which focused outpatient for mild disease showed similar trend. Practical Implications : This study supports the positive effect of having usual source of care which decrease inefficient outpatient utilization. Promoting physician-patient relationships is important for efficiency of healthcare service.

Occupational safety and health management expense in construction industry means the monetary amount that the purchaser appropriates to prevent various disaster from happening during the construction period by setting aside a certain amount from subcontract based on the construction type and scale. The current appropriation standard of the Ministry of Employment and Labor has been enforced since its stipulation in 1988 although various policy changes for the safety in construction industry, e.g. the development of occupational safety management techniques in construction industry, changes in construction field site environment, cost depreciation, etc., are happening in Korea and overseas. Therefore, it is required at this point to examine whether the current occupational safety and health management expense appropriation is proper or not on the basis of time trend and the changes in the construction industry environment. Accordingly, this study aims at investigating the appropriation of occupational safety and health management expense for construction industry by the construction type and target expense in response to current construction industry environment and proposing the proper appropriation. The above research result proposes the calibration of the appropriation as specified and stipulated by the Ministry of Employment and Labor by the construction type and target expense, which is necessary to reflect the actual condition of the current construction industry environment.

This study examined the trend of floor space characteristics, size characteristics and modeling characteristics so as to evaluate the satisfactory level of subjects living in Hanok. By doing so, the type of Hanok was classified into 5 groups. The satisfactory level was evaluated after the subjects resided in Hanok based on each type of housing. In the satisfactory level investigation, which was conducted after the residence, the overall satisfactory level on Hanok showed to be high. In the evaluation on the residence scale, positive results were generally achieved regarding 'full size of residence', 'number of rooms compared to residence size', 'size of living room', etc. The indoor environment of residence evaluation mainly showed positive results regarding 'ventilation', but most subjects were unsatisfied in regard to 'heating', 'noise', 'lighting', etc. In the behavioral factor evaluation of residents, positive results were gained regarding 'health', but comparatively negative results showed based on items of 'construction expense', 'burden of maintenance expense', 'investment value', etc. After analyzing the influential factors on the overall satisfactory level, results showed that 'dust inflow' of the physical site environment evaluation, 'size of living room' of the residence size evaluation, 'heating' of the residence indoor environment evaluation, and 'burden of maintenance expense' in the behavioral factor evaluation significantly influences the overall satisfactory level.
