Abstract In this paper, the experimental paradigm of cognitive behaviors to study the cognitive activities in the contiguous sense cognition of the tested linen clothing is introduced. The experimental program is written with E-Prime 2.0, while the expression of experimental stimulus material is realized with the developed dressing contiguous sense measurement device, which output the senses of urtication, roughness and smoothness among the fabric contiguous sense. Changing the relative force for the contact between fabric and human skin, the dressing contiguous sense is tested in different contiguous force conditions. The result shows that, with the increase of relative contiguous force, the evaluation value for the sense of urtication is increase, the value for the roughness sense is also increase, but that for the smoothness sense is decrease.

A number of statements by the eleventh centurt ascetic Peter Damian concerning purity, impurity and purification are interpreted by means of the so-called Container Schema formulated by George Lakoff and Mark Johnson. According to Lakoff and Johnson humans experience teir bodies as containers and as things in containers. Containers are characterized by the following structural elements: interior, boundary, exterior. Peter Damian is shown to describe impurity as a state of defilement, disease of bodily injury - all phenomena that are caused by a threatened or an actual breakdown of the boundary of the container, i.e. the human skin, the main purpose of which is to separate the interior  from the m enacing exterior. Basically then, impurity is seen as a result of an invasion of the body by foreign substances through the natural orifices, e.g. the senses, or through lesions - substances that may in their turn bring about unwanted discharges in the shape of e.g. semen or - in a metaphorical sense - sinful behaviour. Acts of purification are described by Damian in terms of the same container metaphor. Finally, it is suggested that the container metaphor may serve as a tool in analysing ideas of impurity outside a Christian, monastic context.

Measuring Device

This paper describes the design of a six-component contact force measuring device, the purpose of which is to verify a system of theories that predict the forces found in robotic grasping. The geometry of the device is based upon that of the Stewart platform manipulator, configured symmetrically. The elastic properties of the device as a whole, and of its legs, are analysed and chosen so that the device possesses appropriate characteristics. The resulting design is described, and its calibration and use are reported. Particular attention is paid to the synthesis of the elastic properties of the system, including an elastic central strut to maintain tension in the legs, which themselves are designed for acceptable sensitivity. The whole device is shown to give good results in contact force measurements.

This paper discusses the design and construction of a human body resistance and temperature measurement device. The device measures the human body temperature and resistance when the sensing probes are placed in contact with the human skin. The design analysis was based on simple electronic circuit theories leading to specification and choice of components used for the construction of the system. After the construction and testing with various individuals the human body resistance and temperature was found to be within the ranges of 1KΩ to 210KΩ and 36.10C to 37.50C respectively. The paper discuses the various effect of current on the human body and their implication. The system can be adapted to various fields such as bio-technology, security (lie detector), safety equipment in industries and companies to determine insulation.

This contribution introduces a virtual measurement device for the reconstruction of the in practice unmeasureable railwheel contact forces. For this aim the Proportional-Integral (PI)-Observer is used. Then, the concept of a measurement sleeve at the axle bearing is shown. With the displacement measurements resulting from the sleeve using the PI-Observer, an estimation of the tangential contact force and the dynamic normal force is possible. Using the simulation of the rail-wheel contact, the feasibility of the estimation of the contact force behavior is shown. As an outlook for further applications of the PI-Observer in the context of rail-wheel contact force estimation, the reconstruction of contact forces by using acceleration measurements is demonstrated by an example of an elastic beam for the first time.

A new 1-MeV transmission electron microscope (Model JEM-1000) was installed at the Department of Molecular, Cellular and Developmental Biology of the University of Colorado in Boulder during the summer and fall of 1972 under the sponsorship of the Division of Research Resources of the National Institutes of Health. The installation was completed in October, 1972. It is installed primarily for the study of biological materials without many of the limitations hitherto unavoidable in standard transmission electron microscopy. Only the technical characteristics of the installation are briefly reviewed here. A more detailed discussion of the experimental program under way is being published elsewhere.

Immuno Electron Microscopy

A mouse monoclonal antibody (5C6) prepared against human type VI collagen (1) has been used in this study to immunolocalize type VI collagen in human skin. The enbloc method used involves exposing whole tissue pieces to primary antibody and 5 nm gold conjugated secondary antibody before fixation, and has been described in detail elsewhere (2).Biopsies were taken from individuals ranging in age from neonate to 65 years old. By immuno-electron microscopy, type VI collagen is found to be distributed as a fine branching network closely associated with (but not attached to) banded collagen fibrils containing types I and III collagen (Fig. 1). It appears to enwrap fibers, to weave between individual fibrils within a fiber, and to span the distance separating fibers, creating a “web-like network” which entraps fibers within deep papillary and reticular dermal layers (Fig. 2). Relative to that in the dermal matrix, the concentration of type VI collagen is higher around endothelial basement membranes limiting the outer boundaries of nerves, capillaries, and fat cells (Fig. 3).

Volar Surface

Our laboratory is engaged in the study of the effect of different chemical agents on human skin, using electron microscopy. Previous investigations revealed that topical use of a strong alkali (NaOH 1N) or acid (HCl 1N), induces ultrastructural changes in the upper layers of human epidermis. In the current experiments, acetone and kerosene, which are primarily lipid solvents, were topically used on the volar surface of the forearm of Caucasian and Negro volunteers. Skin specimens were bioptically removed after 90 min. exposure and 72. hours later, fixed in 3% buffered glutaraldehyde, postfixed in 1% phosphate osmium tetroxide, then flat embedded in Epon.

Intercellular Lipid

Keratinocytes undergo maturation during their transit through the viable layers of skin, and then abruptly transform into flattened, anuclear corneocytes that constitute the cellular component of the skin barrier, the stratum corneum (SC). The SC is generally considered to be homogeneous in its structure and barrier properties, and is often shown schematically as a featureless brick wall, the “bricks” being the corneocytes, the “mortar” being intercellular lipid. Previously we showed the outer SC was not homogeneous in its composition, but contained steep gradients of the physiological inorganic elements Na, K and Cl, likely originating from sweat salts. Here we show the innermost corneocytes in human skin are also heterogeneous in composition, undergoing systematic changes in intracellular element concentration during transit into the interior of the SC.Human skin biopsies were taken from the lower leg of individuals with both “good” and “dry” skin and plunge-frozen in a stirred, cooled isopentane/propane mixture.

Human Skin Equivalent

In intact skin the epidermal layer is a dynamic tissue component which is maintained by a basal layer of mitotically active cells. The protective upper epidermis, the stratum corneum, is generated by differentiation of the suprabasal keratinocytes which eventually desquamate as anuclear comeocytes. A similar sequence of events is observed in vitro in the non-contracting human skin equivalent (HSE) which was developed in this lab (1). As a part of the definition process for this model of living skin we are examining its ultrastructural features. Since desmosomes are important in maintaining cell-cell interactions in stratified epithelia their distribution in HSE was examined.
