The purpose of this thesis is to analyze the present conditions and problems of the Electronic Commerce, specially by the fashion companies that utilize the Internet and to propose using plans of Internet Electronic Commerce as a strategic method of fashion companies that have a information-oriented mind to adapt itself to modern century. On the basis of my analysis, I propose some using plans of Internet Electronic Commerce by the fashion companies as follows. As a means of construction method, it is need for the pertinent companies to have an information-oriented mind and then to construct the low-expense but high-speed communication Infrastructure. As an operation and management method, positive web site advertisements plans, such as promotion, using various mass media, subscribing to the Internet search engines and dissemination of products information, etc., are need for companies to attract the consumers to connect to the web site. Second, to offer more satisfactory experiences, it is need for companies to frame the integrated shopping mall as a strategic alliance in the management of shopping mall. To frame the integrated shopping mall is also effective in solving financial problems of shopping mall management and introducing of security system As a means of technology supplement, security management systems, such as SSL or SET, should be introduced for consumers to pay the price and furnish their personal informations. Second, new technology developments, such as the newest simulation programs using Virtual Reality to solve the problem of products' actual feeling, should be need for consumers to feel as they really put clothes on. If these technological developments are realized, fashionable products will be dealt in the Internet shopping mall as well and the marketability of Internet shopping mall will be expanded.

As a part of the ITS, the traffic information system is more widely adopted to deliver traffic information to vehicle drivers via various types of media. As the ITS system establishment has been recognized as somewhat accomplished, the focus has shifted to the efficient operation and maintenance of the system. In this paper, we propose a method for evaluating a VMS traffic information service system from a user's perspective. In particular, relational expressions for the level of information provided and the level of user satisfaction are generated for the evaluation to take place from the user psychological satisfaction aspect of all other beneficial features of the system. As continuous flow facility is the one that has limited entry and exit, the traffic information of VMS plays a significant role for vehicle drivers to make their decisions. A method suggested in this paper could be used for evaluating an existing system as well as setting up the target service level of the system of a new system. If individual system properties are considered along with various VMS functions being as supplement of this research, more systematic evaluation method could be arranged.

The alginate extracted from Hizikia fusiform by the acid alkali soluble alginate (AASA) extraction method was reacted with Na$_2$SO$_4$. The amount of sulfate absorbed in the 3% alginate solution was determined about 18,435 ppm by inductively coupled plasma-atomic emission spectrometry. Both alginate and S-alginate stimulated the growth of Lactobacillus acidophilus in MRS broth and peptone water medium. The addition of S-alginate to the media showed the higher bacterial numbers than alginate supplement. There was no mutagenic activity of S-alginate in the Ames test using the Salmonella Typhimurium TA98 and TA100 strains. The S-alginate showed suppressive effect against 2-NF and MMS of mutagens.

Effects of nitrogen sources, supplement of vitamins and minerals on the accumulation of 5'-inosinic acid by an adenineless mutant of Brevibacterium ammoniagenes were examined. Maximal yield of 5'-inosinic acid was attained by the use of yeast extract. as organic nitrogen source Casamino acid supplemented with $Mn^{＋＋}$, $Zn^{＋＋}$ Ca-D-pantothenate and thiamine HCl could be subsitute for it. Subsequent experiment using the defined medium showed that the concentration of these trace element in the medium affected inosinic acid accumulation markedly. And it was found that the simulataneous addition of $Mn^{＋＋}$ (20$\mu\textrm{g}$1). $Zn^{＋＋}$(10$\mu\textrm{g}$1). thiamine Hcl(10mg/1) and Ca-D-pantothenate (5mg/l) to the defined medium stimulated inosinic acid accumulation, from which 7mg/ml of inosinic acid was obtained.

In this digital information era, utilization of images are essential for various media, and the edge is an important characteristical information of an object in images that includes the size, location, direction and etc. Many domestic and international studies are being conducted in order to detect these edge. Existing edge detection methods include Sobel, Prewitt, Roberts, Laplacian, LoG and etc. which apply fixed weight value. As these existing edge detection methods apply fixed weight mask to the image, edge detection characteristic appears slightly insufficient. Accordingly, in order to supplement these problems, this study used bottom-hat transformation from mathematical morphology and opening operation in improving the image and proposed an algorithm that detects for the edge after calculating mask-based gradient. And to evaluate the performance of the proposed algorithm, a comparison was made against the existing Sobel, Roberts, Prewitt, Laplacian, LoG edge detection methods, in illustrating visual images, and similarities were compared by calculating the MSE value based on the standard of each image.

There are several methods currently being used to diagnose tuberculosis in patients, such as smear, PCR, tuberculosis culture and X-ray. For a proper medical treatment, antimicrobial susceptibility test and rapid drug susceptibility testing have been operated. Tuberculosis bacilli usually need 3~8 weeks of culture period because of delay in RNA synthesis and require 15~22 hours for generation. After a germ raises in culture, we initiated antimicrobial susceptibility test for a proper treatment. It has some difficulties to give a proper prescription for a tuberculosis patient because antimicrobial susceptibility test requires 4 weeks. To supplement this, we are practicing drug susceptibility testing which allow us to know the sensibility of RMP and INH after 2 or 3 days. But this is only possible when more than 2 positive germ. Therefore, we should practice rapid drug susceptibility testing with culture test. But if media is contaminated by other germs except Mycobacterium tuberculosis, it's hard to interpret result about culture test and to practice antimicrobial susceptibility test and rapid drug susceptibility testing. Because we have to practice again smear, culture test after extracting specimen from the patient, time is consumed and proper patient treatment is postponed. To address these problems and quick patient treatment, rapid drug susceptibility testing is practiced by using GenoType$^{(R)}$ MTDRplus method. As a result of this method we detected sensibility 10 and 7 cases and resistance 0 and 3 cases using RIM and INH respectively with other 1 case toward medicals out of the total 11 test. In conclusion rapid drug susceptibility testing can be used from the contaminated specimen after elimination of contaminated source from culture and proved that it can be practiced for rapid examination of a tuberculosis patient.

We investigated the optimal culture conditions for Cryptosporidium muris in a human stomach adenocarcinoma (AGS) cell line by determining the effects of medium pH and of selected supplements on the development of C. muris. The optimum pH of the culture medium required for the development of C. muris was determined to be 6.6. The number of parasites significantly increased during cultivation for 72 hr (p < 0.05) at this level. On the other hand, numbers decreased linearly after 24 hr of incubation at pH 7.5. When cultured in different concentrations of serum, C. muris in media containing 5% FBS induced 4-7 times more parasites than in 1% or 10% serum. Of the six medium supplements examined, only 1 mM pyruvate enhanced the number of C. muris in vitro. Transmission electron microscopic observation showed the developmental stages of C. muris in the cytoplasm of the cells, not in an extracytoplasmic location. The growth of C. muris in AGS cells provides a means of investigating its biological characteristics and of testing its response to therapeutic agents. However, a more optimized culture system is needed for the recovery of oocysts on a large scale in vitro.

This retrospective study was conducted to investigate the growth of children and their care person's weaning behaviors and its relation between the growth and care person's attitude and behaviors about weaning. 272 subjects who had child under 2 years old at that time were randomly selected and answered the special questionnaire. Results were as follows: Using to Kaup index, 13.4% of children were estimated undernutrition, 60.6% were normal and 26.0% were estimated overnutrition. 97.6% of respondant (children's mother) were recognized the need of weaning and the first prurpose of weaning was supplement of nutrients, and the next one was to set up normal food habits. 39.1% of subjects were used normal adult foods as weaning food. 60.9% of subjects were proepared special foods (making at home or buying commercial weaning food). The socioeconomic status was major factor to influence mother's behaviors about weaning. Vegetable and meat gruel was the most commen weaning food and the next one was fruits puree and rice with soup. The correlationship were found between Kaup index and the score of mother's weaning behaviors, between momer's eductional level and the score of weanig behaviors. 96% of subjects wanted nutritional education about weaning. They wanted to know about desirable weaning process and correct informations of commercial weaning foods mid the convenient cooking methods. According to the difference of socioeconomic status subjects were wanted different eductional methods. Upper socioeconomic group wanted special books about weaning and lower class wanted to be educted through the mass media especially television programs.

Realistic videos using multi-view videos are created so that the contents shown on multi-view displays or screens look realistic. These images have been mostly used for special videos for exhibition, but, recently, systems such as Screen X have given rise to multi-view images as a format for storytelling contents such as movies. This study used HD-level broadcasting digital video camera with three zoom lenses for shooting wide to close-up shots focusing on a person, in the same way as Screen X, and identified and analyzed problems found during multi-view image registration correction. The results of this study suggested, provided the shooting technique and equipment are improved, the multi-view format can be used for conveying stories and information. Future research will need to investigate and supplement relevant techniques that will enable production of high-quality multi-view image contents by using a cinema-grade camera with standard lenses, instead of using broadcasting-grade zoom lenses.
