The central focus of this research paper is to explore the recent structural core empirical unemployment reason of IT new professional manpower who graduated in higher education level in Korea. The final goal of this issue is to estimate and analyze rambling impediment in IT manpower labor market between 26 detail occupations and between detail occupations and 3 educational levels of new graduates and entrants who entered in IT 6 occupational groups composing 26 particular occupations. This study uses the 2004 data published by the Ministry of ICT and relies upon both one-way analysis of variance and two-way analysis variance to tackle the issue. According to the ANOVA results, 2 main points were delineated In the one-way analysis of variance method. the total sum of squares (SST) is decomposed into two major components: within sum of squares (SSW) (6 detail occupations, 85%) and between sum of squares (SSG) (26 detail occupation, 15%) The other major finding is that total sum of squares (SST) is decomposed into three major components: between detail occupations (SSG) (19.3%), between educations (SSB) and errors (SSE) (56%) in IT SIW development design group.

The increasing importance of IT rose to the top of list of marketing managers' key concerns and IT has been used widely in performing various marketing activities and decisions. However, little was known about how to employ IT in various marketing activities and how to use IT as a strategic marketing means. Also, comprehensive empirical studies have rarely been conducted. This study examines the effectiveness of integrative use of marketing and IT. More specifically, this study attempts to identify the factors that influence the effectiveness of marketing information systems. The manufacturing firms listed in the Korean Stock Market were surveyed. the major findings of this study are as follows. First, the variables of organizational characteristics such as formalization of decision making cooperation between marketing function and IS function, and degree of decentralization were significantly related to the success of marketing information systems. The variables of user highly associated with the success of marketing information systems. Second, it was also found that the support capability of marketing information systems is the major factor of the effectiveness of marketing information systems. Third, the variables marketing function and IS function, and ratio of export sales to total sales were three variables such as marketing knowledge of marketing managers, cooperation were the main factors to affect the users' satisfaction with the information system. These results imply that, in order to increase the effectiveness of marketing information systems, a firm should enhance a cooperation between marketing function and IS function, diversify the support capability of IS, and strengthen the computer mind and computer knowledge of end-uses.

In oriental medicine, it is well known that Angelica gigantis tonifies and harmonizes the blood, regulates the menses, and moistens the intestines. This herb has been used for deficient blood pattern, menstural problem, abdominal pain, and traumatic injuries in oriental medicine. A major component of Angelica gigantic consist of a various coumarines, decursin, schooltime, umbelliferone, safrole, 3-butylphalide sistesterol. In this study, we aimed to measure the contents of decursin, one of major coumarine derivative, to determine the standardization of Angelica gigantis.

There was no a difference of genetic analysis among methods(means, joint scaling test, 3 Parameter model) . The magnitude of additive effects generally paralleled the magnitude of difference between parental means and appeared to be more independent from non-allelic interaction than did dominance effects, whereas the magnitude of dominance effects were inflated by non-allelic interaction. Additive effects were significant for all characteristics observed and it was a major effects in inheritance of number of leaves. Dominance effects were higher than additive effects for plant height, days to flower, flesh leaf weight per plant, curing rate, total alkaloid and total nitrogen.

It is well known that Dioscoreae Rhizoma tonifies and benefits the Spleen and Stomach, benefits the Lung and nourishes the Kidney. A major component isolated from this herb consist of dioscin, diosgenin, allantoin, starch, alanin, mucilage, choline, amylase, and glycoprotein. In this study, we aimed to measure the content of allantoin, one of major component, to determine the quality of Dioscoreae Rhizoma.

An urban railway vehicle has a characteristics such as that a lot of passenger use it and the major of passenger is standee. The ride comfort of standee is greatly influenced by the lateral dynamic characteristics of vehicle. So the lateral vibration is important factor for the improvement of ride comfort. In this study, vibration test of railway vehicle is carried out under the same condition of field driving to find out the major factor of vibration. By considering the test results under the various driving condition, the vibrational characteristics of vehicle is verified.

It is widely accepted that free-radical induced oxidative damages are involved in pathogenic processes of major diseases including cancer, atherosclerosis, rheumatoid arthritis and diabetes. A number of epidemiological studies have indicated that frequent consumptions of plant foods rich in antioxidants reduce the risk of developing cancer and cardiovascular diseases, while many intervention trials have failed to prove the protective role of major dietary antioxidants.(omitted)

ECG analysis is main techniques for diagnosing heart disease. In recent, some studies have been performed about detection of QT interval. But, it's difficult to detect QT interval because T wave is evasive. In this paper, we have detected peak point and end point of T wave and calculated QT interval. And the result has been compared with the other algorithm after detection of QT interval.

It is well known that Crataegus Fructus strengthens the Stomach and Spleen, helps digestion, tonify stomachache, and decreases bleeding. A major component isolated from this herb consist of carotene, riboflavin, quercetin, chlorogenic acid, amygdalin, ursolic acid etc. In this study, we aimed to analyze the changes of liquid chromatogram pattern, one of major standardization method, to determine the quality of Crataegus Fructus.
