Soil is polluted by an agricultural chemicals, the effluence of a crystal and sewage sludge, illegal discharging of waste water or waste matter and so on. Soil pollution that accompanies a groundwater and the crops contamination has a large effect on people's living. By polluters pay principle, when a soil was polluted, polluters take the responsibility of clean-up and compensation for damages. The character of the responsibility is a strict liability. When joint polluters exist in a soil pollution, they bear collective responsibility. But they are exempted from obligation in case of a natural calamity and war. The polluters who are poor contribution of pollution take a partition responsibility but it is not easy to prove that. The concerned parties of purification liability in a soil pollution are polluter, an owner or occupant of a contaminated site, and a grantee. But when we do not appoint the polluter or he cannot do a cleanup, municipal must put in effect the purification. In such a case, another parties who are related to the contamination should take upon themselves a liability. The province of responsible parties, therefore, is required to extend to an owner or operator of a facility, a carrier and lender.

Human Engineering has an intention of design to keep the best condition of man-machine system. Hitherto the conception of design has been used to include existing engineering, as mechanical engineering and electric engineering. But the manufactured goods which to be made these process seem to be fully equipped on physical function, but faults come out discountent repeatedly to users. Accordingly, the development of industrial design has been demanded for improving functional design. It is considered that industrial design has aesthetical sensation. In actually, it must be 1. to provide for utility and safety, 2. easy for maintenance, 3. cheap at cost. 4. possible for sales appeal, 5. and good on appearance. As taking into consideration above five conditions, however, for 삯e sake of comprehend to human being about operating method of machinery and equipment, it should be reflected to design what kind of training way will be needed. Also, it must be considered what a certain extent would be occurred tiredness to human being. in other words. it should be considered the design to be possible the reflect to principle of motion economy, It should not be made adoption of human ability for the designed machinery, it must be adopted the method to consider the design on presuppose about human ability. For study of these actual fact, this paper is summarized the essence of human engineering, and also to find out the methodology as humanistic engineering, It is, Particularly, subdivisionization of operation in flow operation is essential direction of mechanization. Generally. as developing the subdivisionization of operation, it will be lack of satisfaction on operation which worker take charge of. The subdivisionization of operation makes the operation to simple-repetitive, to lose the interest of worker and will be also come into question to the feeling of worker's livelihood. It is human's fundamental desire to have get skilful function or special technique. But the subdivisionization of operation hold in those human's fundamental desire and so that it will likely to lose the sorority of living by this fact. Accordingly, this paper have an operation to hold out the methodology on presuppose about human ability.

It is difficult to obtain sufficient healthy skin for coverage of a wide area of skin wound. In the skin, an additional population of living epithelial cells is located in the outer root sheath (ORS) of hair $follicles.^{1),2)}$ ORS cells should be a good source of epithelium because they are easily obtainable and patients do not have to suffer from scar formation at donor sites. We modified ordinary primary culture technique for the purpose of solving such problem that epithelial cells have a low propagation and easy aging during culture periods. First of all, we improved primary cultivation methods. In the ordinary primary culture, average yield of human ORS cells was $2\;{\times}\;10^3$ cells/follicle by direct incubation with trypsin (0.1%)/EDTA (0.02%) solution for 15 min at $37^{\circ}C$ but we could obtain about $6.5\;{\times}\;10^3$ cells/follicle by two step enzyme digestion method with dispase (1.2 U/ml) and trypsin (0.1%)/EDTA (0.02%) solution. So we could achieve three times higher primary cultured ORS cell yield. Secondly, we could obtain total $2\;{\times}\;10^7$ cells in serum free medium and even more total $6\;{\times}\;10^7$ cells in modified E-medium with mitomycin C-treated feeder cells during 17 days. Using the cultured ORS cells, and we could make bioartificial skin equivalent in vitro and concluded that ORS cells were progenitor cells for skin epithelial cell.

According to Li Sizhen, Drinking a little makes heart health, spirit active and let be relieved of fatique. Also it hastens gastroenteric digestion. In result, the appetite is stimulated. So Good-wine is useful for well-being necessary to treat a disease much more. However if drink to excess, it will cause mental disorder, exhansted blood, Impairment of stomach. As a consequence of that. Essence of life is exhausted too. So phlegm forms, Fire is more active easily. [In compendium of Materica Medica], 120 classes of counteracting Alcohol Drugs find room in it. Like this, an abundance of data and investigation about Counteracting Alcohol Drugs provides to us a large of Medical materials, and is a guide in Developing and Using the herbal resources. [Lei Gong's Nature of drugs in Songs] says 'Wine have a effect that get out Extravasated Qi and get rid of Pathogen, Abdominal mass with distension and pain.< As it says, ancient doctors displayed remedical Value that promote Qi and Blood circulation as a power of wine. But others says, 'To drink a wine as a drinking water makes us so intemperate, lets us be so being unreasonable easily as to drink hard and hurt our body. (1)Drink with nutritive appetizer. (2) Drink with sitting down. (3)Drink slowly. (4)Do not drink a differ on wine that is not true who makes. (5)Go easy on the alcohol. If drink with this position. Never drink hard for hurting body. Therefore, Cao Tingdong lived in the qing dynasty says "A preventing as a medicine is not so good as a preventing as a temperate living and meal."

There are few research on the social drinking experience reported by women. Thus, it is necessary to understand the increasing tendency of womens drinking experience in the sociocultural context. This study was aimed to explore and delineate the drinking experience of full-time house wives base don Strauss and Corbin's grounded theory (1998). The subjects of this study were 10 full-time middle-aged house wives who were living in Seoul region. The data were collected through several in-depth interviews and observations until the theoretical saturation was achieved. The data were analyzed using Strauss and Corbin's grounded theory method. The results of this study generated a paradigm that the drinking experience of the full-time middle-aged house wives has a core category of 'free-oneself-from' and is also connected with mingling, anguish, accessibility, reaction of other people, change, personal resources, self-expression and building relationships by drinking. All processes from the occurrence of the central phenomenon to extinction are as follows; 1) Starting the process of the drinking experience for mingling and resolving anguish, and by having an easy accessibility; 2) Perceiving the process of reaction by other people, physical change of herself. and psycho-behavioral change; 3) Experiencing the process of free-oneself from thorough drinking; 4) Acknowledging the process of the resources for free-oneself-from; 5) Selecting the process of self-expression according to the resources; 6) Building the process of the relationship with drinking as a way of self-expression. Based on this paradigm, 4 hypothesis and 4 types are generated. Thus, this study suggests that it is useful to develop nursing interventions to improve the self-esteem of the full-time middle-aged house wives and to provide them various methods of problem solving strategies. This study also proposes that there should be a strategic program for the women so that they could make a route for positive self-expression by achieving a proper relationship with drinking.

In spite of the bad conditions of fashion companies: the number of licit wear consumers in Korea are increasing because knit wear gives a body with an comfort action. Domestic knit wear industry, however, doesn't have any standard fur satisfying consumers'needs and for quality estimation on that. So we examined the knit wearers'conception of the quality to broaden the knowledge of knit wear and produce better products. The purpose of this study was to find out the factors of wearer's perception. This study carried out through a qualitative approach. The subject of this study were 17 single women who were 20's and living in Seoul and Kyoungki province. The item of this questionary was as follow: 1) what they know about knit wear and how much they are satisfied with that 2) what the wearers think the problems of knit wear are 3) how knitted wear industry can satisfy consumers's needs and take into account consumer feedback in product development The results of this study were summarized as follows. 1. The wearers had no knowledge about materials, sewing methods, patterns, knitting methods, and gage. 2 The wearers didn't recognize the differences between the products by famous brand and obscure conventional market. For that reason, the high price knit wear wont satisfy wearer. 3. The wearers didn't prefer the revealing their body shapes. 4. Laundering was the big problem which was they chosen the knit wear. They take it for granted that the knit wear needs dry-cleaning or hand-washing. Knit wear industry tries to make it easy laundering by development knit material.

Human have more complicate and skilled ability for lying even cheat ourself. It is not easy to cheat unconscious things like sweat, eyes, or voice, but if some one cheat own self, he can cheat every of that. Lie is one of the way to spread our gene and our instinct make a lie. Every living organism even bacteria or virus use similar trick to survive. In human body, there are more complicate and profound mechanism for lying like breathe, sweat, eyes, face or voice. We can control some of that and make a fake, but it can't be perfect. Human also called 'Homo Fallax' cause we have a language and skill to lie with it. In present, we can detect lie with polygraph, but it has few weakness. So we try to use Vibraimage technology for resolve it. In this paper, we describe how to use Vibraimage for lie detection and the research history.

Surface enhanced Raman scattering (SERS) was first discovered in 1974 by an unexpected Raman signal increase from Pyridine adsorbed on rough Ag electrode surfaces by the M. Fleishmann group. M. Moskovits group suggested that this phenomenon could be caused by surface plasmon resonance (SPR), which is a collective oscillation of free electrons at the surface of metal nanostructures by an external light source. After about 40 years, the SERS study has attracted great attention as a biomolecule analysis technology, and more than 2500 new papers and 500 review papers related to SERS topic have been published each year in recently. The advantages of biomaterials analysis using SERS are as follows; ① Molecular level analysis is possible based on unique fingerprint information of biomolecule, ② There is no photo-bleaching effect of the Raman reporters, allowing long-term monitoring of biomaterials compared to fluorescence microscopy, ③ SERS peak bandwidth is approximately 10 to 100 times narrower than fluorescence emission from organic phosphor or quantum dot, resulting in higher analysis accuracy, ④ Single excitation wavelength allows analysis of various biomaterials, ⑤ By utilizing near-infrared (NIR) SERS-activated nanostructures and NIR excitation lasers, auto-fluorescence noise in the visible wavelength range can be avoided from in vivo experiment and light damage in living cells can be minimized compared to visible lasers, ⑥ The weak Raman signal of the water molecule makes it easy to analyze biomaterials in aqueous solutions. For this reason, SERS is attracting attention as a next-generation non-invasive medical diagnostic device as well as substance analysis. In this review, the principles of SERS and various biomaterial analysis principles using SERS analysis will be introduced through recent research papers.

This paper focuses on the use of the virtual dialog system whose aim is to build more convenient living environments. In order to realize this, the main emphasis of the paper lies on the description of the multimedia signal processing on the basis of the technologies such as speech recognition, speech synthesis, video, or sensor signal processing. For essential modules of the dialog system, we incorporated the real-time speech recognizer based on HM-Net(Hidden Markov Network) as well as speech synthesis into the overall system. In addition, we adopted the real-time motion detector based on the changes of brightness in pixels, as well as the touch sensor that was used to start system. In experimental evaluation, the results showed that the proposed system was relatively easy to use for controlling electric appliances while sitting in a sofa, even though the performance of the system was not better than the simulation results owing to the noisy environments.
