Since the Internet was applied for commercial purpose, many companies have been making use of the internet in electronic commerce and the internet has brought many changes on consumer and supplier behaviors. It seems that consumers and suppliers can obtain more accurate information rapidly and pay less for the same product/service than in traditional commerce. This study tries to investigate the difference in the cost factors perceived by consumers between traditional commerce and the Internet commerce. Empirical results show that there is no significant difference in consumers' perception of cost factors between traditional commerce and the internet commerce Contrary to general perception, a large number of consumers do no, believe that the internet commerce is generally more economical than traditional commerce. The factors where the consumers think Internet commerce has cost advantages are search cost and purchasing cost. However, consumers are understanding the benefits of the internet commerce and are expecting that internet commerce bring about economic advantages in consumer markets in the near future.

Depressive disorder is prevalent illness. When depressive symptoms become qualitatively different, pervasive, or interfere with normal function, they are considered to be pathological. Major depressive disorder is defined as depressed mood or anhedonia lasting at least two weeks plus a set number of psychologic or physical symptoms. Dysthymia has fewer symptoms than major depression and is a chronic illness lasting at least two years. A condition known as depressive disorder not otherwise specified includes conditions that do not have enough symptoms (fewer than five) or are of insufficient duration to be considered major depressive disorder. Depression is second only to hypertension as the most common chronic condition encountered in general medical practice. A diagnosis of depressive disorder can be complicated by concomitant illnesses or medications that mimic the symptoms of depression. The keys to successful management of depression include thorough screening, patient engagement and education, early follow-up of adherence to the treatment plan and careful monitoring of response. By putting these strategies into practice, family physicians can provide excellent care for their depressed patients and, in many cases, help them achieve lasting remissions.

There were many studies about correlation between fatty liver and serum triglyceride level. However, we have experienced many fatty liver patients that actually did not show high serum triglyceride level. So, we conducted this study to reconfirm the con-elation between fatty liver and serum triglyceride level. We randomly selected 118 patients in Health Examination Center. We divided the selected materials into the patient and control group by the level of fasting serum triglyceride level, 200mg/d.L. We analyzed frequency and distribution of factors(age, body mass index, alcohol, diabetes mellitus) related to fatty liver between patient and control group. Then we analyzed odd ratio of fatty liver among two groups. There were 22 peoples in patient group and 96 people in control group. There were no statistical differences in the mean body mass index, the frequency of overweight, the frequency of alcohol users, the mean fasting serum glucose, and the frequency of diabetes mellitus patients between patient and control group. The odd ratio of fatty liver among two groups did not mean statistical difference. However, there was statistical significant difference in the frequency of body mass index on the base of multiple logistic regression analysis of serum triglyceride level, body mass index, and frequency of diabetes mellitus, and alcohol users between patient and control group. There was no correlation between fatty liver and serum triglyceride. But there was correlation between fatty liver and body mass index.

As average lifespan in human increased, women's concerns about health promotion after postmenopause are increased. Osteoporosis causes the serious health problem in postmenopausal women. We investigated comparison between Seoul and Chungju for women's recognition about osteoporosis to utilize patient's education data. Information, concerning whether the osteoporosis was well understood, were gather 405 patients, who visited an university hospital from January 1 to April 30, 2001. The mean age of 201 women in Seoul is 46.39 years old, and mean age of 204 in Chungju is 46.35 years old. Among 201 women in Seoul, 43(21.4%) women answered "well known" osteoporosis, and 32(15.9%) women answered "unknown" osteoporosis. Among 204 women in Chungju, 24(11.8%) women answered "well known" osteoporosis, and 32(15.9%) women answered "unknown" osteoporosis. There were significant association between recognition of osteoporosis and their education level, but not significant related with their economic level. Subjective and objective recognition for osteoporosis in Seoul was relatively higher than women in Chungju, but compliance about doctor in Chungju was relatively higher than women in Seoul. But we found that recognition level of postmenopausal osteoporosis is low in Seoul and Chungju. We concluded that knowledge for osteoporosis was relatively low, seoul was relatively higher than in Chungju. Therefore, correct patient education for prevention and treatment of osteoporosis would be needed.
