The skin is an organ that covers the outside of the human body. And it regulates body temperature, performs sensory function, deliveries the drug, and represents the abnormality of the internal organs. For these reasons, people have been expressing the condition of the body based on the state of the skin of the face to detect sign of health, "you look well", "face with vitality". Depending on the degree of aging and the environment, it is a fact that skin color, skin texture, moisture and firmness could be different. In particular, the color of the skin acts as a factor that affects to determine the subjective impression such as beauty and charm. We could expect consumer's demand through the market of whitening cosmetics and skin treatment. However, existing most of the cosmetics focus on improving whiteness. The number of studies that focused on skin color is not enough. In this study, we found out the skin color condition by carrying out surveys of 100 women between 30s and 40s. Our study would be very useful to develop new cosmetic products and to satisfy customer's needs.

In order to utilize sea mustard, Undaria pinnatifida, effectively. sea mustard jam was prepared by use of physical properties of polysaccharides, mainly alginic acid and then its chemical composition, nutritive qualifies and the stability of pigments were examined. Suitable processing condition for sea mustard jam was as fellows : as the first stage, fresh sea mustard was scalded for 20 sec at $85^{\circ}C$ and dried sea mustard was dipped for 20 min in cold water for rehydration, then both sea mustards were treated by draining and chopping. Next, after adding 4 fold of $0.5\%\;K_2HPO_4$ solution to weight of chopped sea mustards, the mixed solutions were agitated for 15 min at $95^{\circ}C$, and gelated sea mustards were filterated by pressing. Flow characteristics of those sea mustard jam were regarded mixed type having pseudoplastic type and yield stress. Judging from sensory evaluation, adding $0.375\%$ of saccharin, $2\%$ of sorbitol, $0.25\%$ of citric acid and $0.5\%$ of powder of roasted soybean to sea mustard jam were suitable for enhancing taste and flavor of product. Chemical composition of products were scarcely changed throughtout processing. Jam processed by fresh sea mustard was better than dried one in contents of chlorophyll and total carotenoid pigments. In fatty acid composition, polyenoic acids of $C_{18:3},\;C_{20:4},\;C_{20:5},\;C_{22:6}$ were held high contents as known to have lowering function of cholesterol contents. It was presumed that dominant contents in free amino acids such as lysine, alanine, glutamic acid and organic acids such as citric acid, oxalic acid, $\alpha-ketoglutaric$ acid, lactic acid and succinic acid held important role for the flavor of sea mustard jam.

This study was to identify the nursing intervention method in finding out the incidence, risk factor, prevention and treatment of bed sore cilents who received regional home care nursing services. The eleven home care nurse practitioners took the survey on 97 patients who received home care nursing service from Seoul City Nurses Association for one month from September 26 to October 26 1996. A modified version of Braden's bed sore assessment tool for bed sore risks and a tool for assessment of bed sore stage and measurement bed sore sizes by Bergstrom, Braden, Laguzza and Holman(1987) were as research tools for this study and a questionnare with 40 questions and 12 items on nursing activities was used to find out the prevention and treatment of bed sores. Also, two open ended questions were used on current approaches and efforts of the treatment being applied to clients. The finding of the study were summarized as following : 1. The rate of bed sore occurrence was 47.4% 2. The areas of bed sore occurrence were hip(28.9%), sacrum(18.6%), great trochanter(14.4%) and the average number of sore spots were 2.26 3. Two groups-one with bed sores and the other without-were studied to determine prediction factors for bed sore risks. Sensory function, humidity, level of activity, mobility, nutrition, skin friction and chapping and body temperature turned out to be statistically significant factors for bed sores. Also the age of clients turned out to be a individual characteristic variable significantly affecting the rate of bed sore occurrences. 4. The education for clients and family on systematic skin assessment and bed sores and practice of active/passive R.O.M. are mainly used as nursing activities for bed sore care. 5. The treatment method varied by stages of bed sores. Sometimes folk remedies like applying the powders of dried elm tree roots to sores were used. Good nutrition, frequent position change and skin care turned to be the most effective means to fast recovery of sores.

This study was conducted to evaluate the breadmaking characteristics of white bread when rice bran (RB), fermented rice bran (FRB) and rice bran oil (RBO) were added to the dough. Addition of RB to dough generally showed a decrease of the bread volume and increase of the bread weight which is related to the comparative decrease of gluten in the dough. Addition of RB also showed a decrease of lightness with yellowish color of RB and showed some rheological changes in dough. However, up to 5% RB addition, the dough showed a similar property of breadmaking with giving functional benefits compared to the control. Moreover 5% FRB addition to the dough improved the taste, flavor, and texture important to quality of bread. Substitutional use of RBO for shortening in dough result in comparative decrease of volume of dough. Addition of yellowish RBO influenced the increasing yellowness score, hardness, gumminess and brittleness, which is disadvantageous for the quality of white bread. However up to 50% RBO substitution for shortening made little rheological differences compared to the control. The 50% RBO substitution for shortening increased the score of flavor in sensory test even if there was an unfavorable quality point of white bread caused by a decreased volume and an increased hardness. From these results it could be suggested that the proper use of RB, FRB and RBO in breadmaking could improve the taste and flavor, giving beneficial function originated from rice bran to white bread.

This study was performed to identify the cerebral network associated with sensation through the tickling stimulation, which is distinctive from the rest of other networks processing normal stimulation and to investigate the difference of laughing mechanism which is closely related to tickling using functional MRI(fMRI). A 16 healthy volunteers (mean age: 28.9) on a 3.0T MR scanner during two sensation conditions. Counterbalanced stimulus were presented across the participants, and the stimulation was used block design. Acquired data was analyzed by the statistical parametric mapping (SPM 99). Subject and group analysis was performed. Individual analysis showed the activation of somatic sensation area in both tasks and the tickling sensation test showed more activated area in the Wernicke's area(BA40) compared to the normal sensation. The group analysis result shows that under normal stimulations, both sides of somatosensory cortices(BA 1,2 and 3) were activated and under tickling stimulation, not only the cortices but also those huge activation on thalamus, cingulate gyrus and insular lobe were detected. When the tickling was stopped, significant activations were shown in right cingulate gyrus, left MFG area and left insular lobe. A cerebral area responsible for recognizing tickling sensation was examined and the primitive stimulation such as tickling is much closely related to laugh, which is an important factor for various social activities.

This study was to investigate central localization of neurons projecting to the urinary bladder and urinary bladder-related acupoints(Wijung, $BL_{40}$) and neurons of immunoreactive to hormones and hormone receptors regulating urinary bladder function by using peudorabies virus(PRV). In this experiment, Bartha's strain of pseudorabies virus was used in rats to trace central localization of urinary bladder-related neurons and urinary bladder-related acupoints($BL_{40}$) which can regulate urinary system. PRV was injected into the urinary bladder and acupoints($BL_{40}$) related urinary system. After six days survival of rats, mainly common labeled neurons projecting to the urinary bladder and urinary bladder-related acupoints were identified in spinal cord, medulla, pons and diencephalon by PRV immunohistochemical staining method. First-order PRV labeled neurons projecting to urinary bladder and urinary bladder-related acupoints were found in the cervical, thoracic, lumbar and sacral spinal cord. Commonly labeled preganglionic neurons were labeled in the lumbosacral spinal cord and thoracic spinal cord. They were found in the lateral horn area(sacral parasympathetic nucleus and intermediolateral nucleus), lamina V-X, intermediomedial nucleus and dorsal column area. The area of sensory neurons projecting to urinary bladder and Wijung($BL_{40}$) was L5-S2 spinal ganglia and T12-L1 spinal ganglia, respectively. In the brainstem, the neurons were labeled most evidently and consistently in the nucleus of tractus solitarius, area postrema, dorsal motor nucleus of vagus nerve, reticular nucleus, raphe nuclei(obscurus, magnus and pallidus), C3 adrenalin cells, parapyramidal area(lateral paragigantocellular nucleus), locus coeruleus, subcoeruleus nucleus, A5 cell group, Barrington's nucleus and periaqueductal gray matter. In the diencephalon, PRV labeled neurons were marked mostly in the paraventricular nucleus and a few ones were in the lateral hypothalamic nucleus, posterior hypothalamic nucleus, ventromedial hypothalamic nucleus, arcuate nucleus, median eminence, perifornical nucleus, periventricular nucleus and suprachiasmatic nucleus. In cerebral cortex, PRV labeled neurons were marked mostly in the frontal cortex, 1,2 area, hind limb area, agranular insular cortex. Immunoreactive neurons to Corticotropin releasiing factor(CRF), Corticotropin releasiing factor-receptor(CRF-R), c-fos and serotonin were a part of labeled areas among the virus-labeled neurons of urinary bladder and Wijung($BL_{40}$). The commonly labeled areas were nucleus tractus solitarius, area postrema, reticular nucleus, raphe nuclei(obscurus, magnus and pallidus), locus coeruleus, A5 cell group, Barrington,s nucleus, arcuate nucleus, paraventricular nucleus, frontal cortex 1, 2 area, hind limb, and perirhinal(agranular insular) cortex. These results suggest that overlapped CNS locations are related with autonomic nuclei which regulate the functions of urinary bladder-relate organs and it was revealed by tracing PRV labeled neurons projecting urinary bladder and urinary bladder-related acupoints. These commonly labeled areas often overlap with the neurons connected with hormones and hormone receptors related to urination.

This research investigated the effect of different onggi containers (Korean earthenware) on the ripening of kochujang (Korean hot pepper paste). The physical characteristics of 'onggi', were evaluated as function of manufacturing variables such as raw material soils (onggi-specific soil, red brown soil, and fine powdered soil) and galzing treatments. The physical properties were then related to the compositional quality changes of the kochujang fermented at $30^{\circ}C$ for 4 months. The porosity of the onggi containers seems to be increased by the content of finer raw soil rather than the chemical component of soil (amount of CaO, MgO, $K_2O$ and $Na_2O$, acting as melting aid in the firing). Natural glaze was measured to contain higher contents of CaO, MgO, $K_2O$ and $Na_2O$ than the other soils, which is desirable property for the fired onggi. The glazed surface showed higher far-infrared radiation emissivity than the non-glazed part. The kochujang fermented in P0-BG (the glazed onggi from 100 % onggi soil) attained higher concentration of reducing sugar, amino nitrogen and nucleotides compared to those in the other onggis. All of these changes of kochujang in P0-BG resulted in significantly better sensory quality than the other treatments.

The plasticity of nervous system is generated not only due to changes in neurons but also due to changes in neuroglial cells. Astrocyte is important for maintaining the normal brain function and controlling the neuronal functions. The amygdala receives an array of important sensory information of danger signals. This information is further transduced and integrated to produce the highly adaptive emotion, fear. In this study, morphometric changes in the cell bodies of astrocytes in the amygdala, induced by prenatal stress and restraint stress were examined. For this purpose. rats were classified into 4 groups; control group (CON), only restraint-stressed (starting on P90 for 3 days) group (CONR), prenatally-stressed group (PNS), and prenatally and restraint (on P90 for 3 days) stressed group (PNSR). Astrocytes were verified with anti-GFAP immunohistochemistry, counter stained with methylene blue/azure II and were examined using the Neurolucida. Results showed that astrocytes in the amygdala of PNS rats had significantly larger cell bodies than did CON rats and this was enhanced further by restraint stress. Thus this data showed that hypertrophy of the astrocytic cell bodies of amygdala complex is induced by prenatal and restraint stress.

The skin is an organ that has many important roles, including protection against infection, regulation of temperature and fluid loss, and sensory function. Injury to the skin, wound repair normally involves: (1) balanced activity of inflammation, (2) the re-epithelial phase and (3) the matrix formation of remodeling phase. Thus, skin wound healing is a finely controlled biological process involving a series of complex cellular interactions. Laser therapy is being implemented with increasing frequency in medicine. Low intensity laser is one that is capable of producing an energy density so low that any biologic alterations are the result of direct irradiation effect, not thermal events. This study was designed to evaluate the efficacy of low intensity laser therapy on skin wound healing in rabbits. A total of 10 male rabbits (New Zealand White Rabbit), age 8 weeks were used. Skin wound were surgically created dorso-lateral on the flank of 10 rabbits (2$\times$2 cm/damage areas). The experimental animals were treated with 5Hz (830 nm wave length) low-intensity laser (MILTA-01 Model) daily for 10 min (1.6 J/$cm^2$) for 12 days. Control animals were sham treated with the laser head. Laser irradiation animals showed a complete remodeling of the epithelial layer, a positive repair of connective tissues, and enhanced the wound closure rate over time as compared to the control animals. Especially, laser irradiation groups improved fibroblast activity, cellular content, granulation tissue formation, and collagen deposition which is resulted in improving the tensile strength of the wound. These findings suggest that laser photostimulation could accelerate healing of open wound in rabbits, and may be benefit in the treatment of open wound, including decubitis ulcers.
