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.

The economic policy of decreasing the electricity price is widely understood to have the effect of stabilizing the general price level and improving the income distribution. However, the impact of electricity price decrease on the income distribution is not quite sure although the electricity price decrease would increase the disposable income of all households. The electricity price change would affect the income distribution through three channels. The first impact on the income distribution is made through the electricity price sructure; Korean electricity price structure is designed to subsidized the industrial sector at the cost of household consumption sector in the sense that the price per unit electricity for industrial sector is much lower than that for household consumption sector. The second impact on the income distribution is created through the disposable household income effect of the price decrease; Relative disposable income effect among households appeared higher to lower income household group and this relative disposable income effect seem to improve the income distribution although the net effect is very small. The third impact on the income distribution is formulated through the net profit effect of entreprise sector; This unearned net profit increase to the already rich industrial entrepreneurs group could create a negative income distribution effect. A simulation of 10% electricity price decrease with all the price structure given was attempted to calculate the net effect of income distribution and it was found the net income distribution effect of flat electricity price decrease to be negative contrary to the general understanding. The income distribution effect would only be one criterion among many other criteria considered in the electricity price making process. The electricity price decrease would be helpful to the price stabilization and price competitiveness of industrial sector. However, it does not improve the general income distribution status by the electricity price decrease with the price structure given.

This study was carried out to compare the dietary behaviors and nutrient intakes among the students(13 years of age) of middle schools between in industrial complex and in non-industrial complex. The subjects of each group were composed of 192 male and female teenagers living in Ansan city in Korea, and this study was performed by questionnaire and dietary survey. As a result, mothers' education level and monthly family income were lower in industrial complex-families(ICF) than those in non-industrial complex-families(NICF). The subjects in ICF took dinner more irregularly than did those in NICF. The subjects in ICF skipped the meals often as there was no person preparing meals'. The subjects in ICF tended to take ra-myun, cookie or bread more often as a lunch, and they considered size and price of snack more imporandy when they chose snack than those in NICF. And the subjects in ICF had lower degree of flood habits and satisfaction on their meals than those in NICF. The daily intakes of calorie, vitamin B$_2$, calcium and iron of subjects of two groups were lower than the Korean RDA, and these intakes were lower in ICF than in NICF. These findings show that dietary behaviors and nutrient intakes were poor among the students of middle schools in ICF, in part it seems to be related to the fact that the group of ICF has low family income and mothers of ICF have the jobs that are finished late or irregularly. Therefore, these results underscore the need to provide the nutritional education for the students of middle schools and their mothers in ICF with respect to the importance of optimal nutrition through sound dietary behaviors during the adolescence.

This study aims to examine the level of precariousness among young adults in South Korea and analyze the factors affecting their subjective well-being by adopting the three forms of precariousness suggested by Rodgers(1989) such as lack of resource, uncertainty and disempowerment as its analytical framework. Structural Equation Model was used for analyzing the path model of self-rated health, income level and social support(three forms of resource) affecting subjective wellbeing through uncertainty and disempowerment. Study population include young adults aged between 19 to 34 with a sample size of 415 using data of the 8th wave of the Korean General Social Survey(KGSS), 2010. Study population is divided into lower-age group (aged between 19-26) and upper-age group (aged between 27-34) in order to examine the differences between age groups by using Multiple Group Analysis. Study results show that three forms of resources, uncertainty and disempowerment had direct effect on the subjective well-being of South Korean young adults and disempowerment had the most significant effect among the factors. In addition, self-rated health and income level had indirect effect on subjective well-being through both uncertainty and disempowerment while social support had indirect effect on subjective well-being only through disempowerment. Results from the Multiple Group Analysis indicate that among the two age groups, income level only has a significant effect on subjective well-being in the upper-age group. In addition, disempowerment had greater effect on subjective wellbeing among upper-age group than the lower-age group. Based on the study results, this paper suggested policy implications and discussion for further research.

The purpose of this study was to identify the impact of various income sources on income inequality of forestry households. Data from the Forestry Household Economy Survey from 2013-2016 were analyzed using the Gini coefficient decomposition method via income source. In particular, the income inequality analysis of forestry households was broken down into separate analyses based on group, i.e., the whole of forestry households and the five income quintile classes. The results of the analyses showed that income inequality of forestry households is primarily affected by forestry and nonforestry incomes and income quintile class. Moreover, income inequality of the highest income quintile class was largely affected by forestry income compared with other sources of income, whereas that of other income quintile classes was largely affected by nonforestry income. Therefore, in order to reduce income inequality in forestry households, it is necessary to increase the proportion of forestry income in the lower four quintile classes. Given that the income of the lowest quintile class is negative, it is necessary to devise ways to improve the proportion and quantity of forestry income. At the same time, as forestry income increases, a policy alternative is also required to improve inequality in forestry income.

To investigate the prevalence and etiologic factors of nursing caries, oral examination was performed on 1,100 kindergarten children from 6 Seoul areas and 3 Hongchun areas. Parents were asked to fill out questionnaires. The following results were obtained: 1. The prevalence of nursing caries among 1,100 in the sample group(age 30-75 months) was 14.8%. 2. Fathers' education level(p<0.05), mothers' education level(p<0.01) and monthly income was higher in caries-free group children. 3. When the dietary tendencies of nursing caries group and caries-free group were compared, no significant differences in the length and method of feeding were found. However, nursing caries group showed higher frequency of bedtime nursing habit(p<0.01), daytime use of bottle as a comforter(p<0.01) and other beverage feeding in addition to milk(p<0.01). 4. When the parents' awareness of caries prevention was compared, caries-free group per formed more frequent tooth cleansing(p<0.05) and periodic dental examination(p<0.01).5. Dental caries experience of mothers was significantly lower in the caries free group(p<0.05). From the above results, it can be concluded that deleterious nursing habit had great effect on developing nursing caries and the incidence of nursing caries was lower among children with parents of higher socioeconomic status.

The purpose of this study was to identify the risk factors of osteoporosis. The data were collected from women who visited Physical Examination Center of a university hospital located in Taejon during the period of September 1997-August 1998. The sample was divided into two groups(the osteoporosis group of 44 cases and the control group of 66 cases). The results were summarized as follows ; 1. Sociodemographic characteristics(education and family income) and BMI showed no significant difference between the osteoporosis group and the control group. 2. There was no significant difference in coffee, unbalanced diet, diet method and meal habit between the osteoporosis group and the control group. 3. The osteoporosis group reported more incidence of operative menopause due to hysterectomy and oophorectomy, but this was not statistically significant. There was no significant difference in use of oral pill use, past disease and family history of fracture between the osteoporosis group and the control group, but the odds ratio(OR 3.11, 95% CI : 1.30-7.41) of present illness was statistically significant in the osteoporosis group. 4. There was no significant difference in the reproductive history including number of delivery and abortion and feeding method between the osteoporosis group and the control group. 5. The osteoporosis group showed significant results of lower menopausal age, shorter duration of menstruation and longer duration after menopause compared to the control group. 6. The osteoporosis group reported significantly lower level of physical activity in such variables as work activity and walking time. 7. A logistic analysis showed that shorter period of menstruation, lower level of physical activity, non-alcohol drinking group, and presence of disease were related to the possibility of occurring of osteoporosis.

Objectives: We aimed to identify the factors related to depression and quality of life in patients with hypertension by using multilevel regression analysis. Methods: In 2019, 229 043 participants in the Korean Community Health Survey were selected as the study group. Individual factors were identified using data from the 2019 Community Health Survey. Regional factors were identified using data from the National Statistical Office of Korea. Multilevel regression analysis was conducted to find individual and local factors affecting depression and quality of life in patients with hypertension and to determine any associated interactions. Results: As individual factors in patients with hypertension, women, those with lower education-levels, recipients of basic livelihood benefits, and those with poor dietary conditions showed stronger associations with depression and quality of life. As regional factors and individual-level variables in patients with hypertension, lower gross regional personal income, fewer doctors at medical institutions, and lower rates of participation in volunteer activities presented stronger associations with depression and quality of life. In addition, the associations of depression with gross regional personal income, the number of doctors at medical institutions, and dietary conditions were significantly stronger in patients with hypertension than in patients without hypertension. The associations of gender and employment status with quality of life were also significantly greater. Conclusions: Policy interventions are needed to adjust health behaviors, prevent depression, and improve quality of life for patients with hypertension, especially for those with the risk factors identified in this study.

Objectives: This study attempted to determine the influence of factors related to suicide attempts in the elderly. Data from a 2017 Community Health Survey were used to find 67,810 subjects aged 65 years or older. Methods: Cross-analysis and logistic regression analysis were conducted by dividing the suicide thought and suicide attempt experience groups. Results: In the group with subjective stress, suicidal thoughts were higher in women 2.748 times (p<0.01) and 1.917 times (p<0.001) in women. In terms of income level, the higher the income level, the lower the suicidal ideation experience. Suicide attempts were 0.708 times lower when mastication was not uncomfortable and 0.170 times lower when the patient was not experiencing depression (p<0.001). Conclusions: The correlation between oral dysfunction and suicidal thoughts and attempts in the elderly has been demonstrated, and it is expected to be used as baseline data for establishing an institutional study.

This study was designed and undertaken to identify the degree of burden and depression in family caregivers of patients with stroke and to determine whether burden was directly related to depression. The data were collected from October 23th to November 20th, 1995. The subjects in this study were 80 caregivers, that is, one family member and 80 patients with stroke who were hospitalized in one oriental medicine hospital located in Taejon City. The questionnaires consisted of questions regarding burden(13 item, 6 point scale) and depression(20 item, 4 point scale). Data were analyzed using percentages, means, t-test, ANOVA and Peason-correlation coefficients, done with the SAS program. The results of this study are as follows : 1. The score for family caregiver's burden was higher than the mid level for the 13 items. 2. The score for of family caregiver's depression was relatively low. 3. The relationship between burden and depression showed a significant inverse correlation. 4. In the relationships between total burden and general characteristics of the family caregivers : there were no significant differences. But, in the relationship between objective burden and general characteristics of the family caregivers ; age and education had statistically significant differences. That is, the 40's group felt more objective burden than any other age group and the high education group more than the illiterate group. 5. In the relationship between depression and general characteristics of the family caregivers ; sex, education and monthly income had statistically significant differences. That is, female caregivers felt more depression than males, and the lower the level of education and the lower the monthly income, the higher the degree of depression. 6. In the relationships between burden and general charateristics of the stroke patients, only subjective burden according to the patients' sex was significantly different. That is, caregivers felt more subjective burden when caring for male patients than for female patients. 7. In the relationships between depression and general charateristics of the stroke patients, only the patients' economic status showed a statistically significant difference. That is, caregivers felt more depression in case of patients' low economic status.
