Sweet persimmon were tested in order to identify their use as secondary material which is excellent in function and taste as food. Samples were soaked for 1 and 5 min with NaCl concentration(0, 1 and 3%) at a certain heating temperature(25, 75 and 95$\^{C}$), and then tannin, vitamin C, flavonol, color intensity, sensory test and textural properties were analysed. The results of the analyses were as follows. Tannins were decreased as heating temperature, NaCl concentration and soaking time were increased, especially, that the control was 420 mg% but decreased 228 and 198 mg% at 95$\^{C}$(1 and 3% NaCl concentration) for 5 min. soaked in each. Vitamin C content also decreased more in higher temperature and NaCl concentration than control(122.4 mg%). Color intensity showed higher value in 1. and b than in heating temperature, NaCl concentration and soaked time longer remarkably, but a value decreased. The peel of sweet persimmons was analyzed myricetin(2.0 $\mu$g/g), quercetin(34.5 $\mu$g/g) and kaemperol(1.1$\mu$g/g), but in pre-treatment sample(95$\^{C}$, 1% NaCl concentration and 5 min. soaked) was showed higher myricetin(9.5 $\mu$g/g) and quercetin(5.5 $\mu$g/g). Textural properties were good in pre-treatment sample(95$\^{C}$, 1% NaCl concentration and 5 min. soaked) such as brittleness, cohesiveness, gumminess and chewiness. In sensory analysis, the pre-treatment samples(95$\^{C}$, 1% NaCl concentration and 5 min. soaked and 95$\^{C}$, 3% NaCl concentration and 1 min. soaked) were showed higher point than others.

Objectives : To evaluate the effects of Head Acupuncture versus Upper and Lower Limbs Acupuncture on signal activation of Blood Oxygen Level Dependent(BOLD) fMRI on the Brain and Somatosensory Cortex. Subjects and Methods : 10 healthy normal right-handed female volunteer were recruited. The average age of the 10 subjects was 30 years old. The BOLD functional MRI(fMRI) signal characteristics were determined during tactile stimulation was conducted by rubbing 4 acu-points in the right upper and lower limbs($LI_1$, $LI_{10}$, $LV_3$, $ST_{36}$). After stimulation of Head Acupuncture in Sishencong($HN_1$), $GB_{18}$, $GB_9$, $TH_{20}$ of Left versus Upper and Lower Limbs Acupuncture($LI_1$, $LI_{10}$, $LV_3$, $ST_{36}$ of Right) and took off needles. Then the BOLD fMRI signal characteristics were determined at the same manner. Results : 1. When touched with cotton buds(sensory stimulation), left Parietal Lobe, Post-central Gyrus, primary somatosensory cortex(BA 1, 2, 3), and primary motor cortex(BA 4) were mainly activated. When $ST_{36}$ was stimulated, Frontal Lobe, Parietal Lobe, Cerebellum, and Posterior Lobe as well as Inter-Hemispheric displaying a variety of regions. 2. In signal activation before and after Head Acupuncture reaction, it showed signal activation after removing the acupuncture needle and right Somatosensory Association Cortex, Postcentral Gyrus, and Parietal Lobe were more activated. 3. In reactions of before and after Upper and Lower Limb Acupuncture, it also showed signal activation after removing the acupuncture needle and bilateral Occipital Lobe, Lingual Gyrus, visual association cortex, and Cerebellum were activated. 4. After acupuncture stimulation, In Upper and Lower Limb Acupuncture Group, left frontal Lobe, Precentral Gyrus and Bilateral parietal lobe, Postcentral Gyrus and Primary Somatosensory Cortex(BA 2) were activated. In Head Acupuncture Group, which has most similar activation regions, but especially right Pre-Post central Gyrus, Primary Somatosensory Cortex(BA 3), Primary Motor Cortex, frontal Lobe and Parietal Lobe were activated. Conclusions : When sensory stimulation was done with cotton buds on four acup-points($LI_1$, $LI_{10}4, $LV_3$, $ST_{36}$), while bilaterally activated, contralateral sense was more dominant. It showed consistency with cerebral cortex function. When $ST_{36}$ was stimulated Frontal Lobe, Parietal Lobe, Cerebellum, Posterior Lobe as well as Inter-Hemispheric were stimulated. In Head Acupuncture, it showed more contralateral activation after acupuncture. In Upper and Lower Limb Acupuncture, it showed typically contralateral activation and deactivation of limbic system after acupuncture stimulation. Therefore, there were different fMRI BOLD signal activation reaction before and after Head Acupuncture vs Upper and Lower Limb Acupuncture which might be thought to be caused by acu-points' sensitivity and different sensory receptor to response acupuncture stimulation.

Archaeal rhodopsins possess retinal molecule as their chromophores, and their light-energy and light-signal conversions are triggered by all-trans to 13-cis isomerization of the retinal chromophore. Relaxation through structural changes of protein then leads to functional processes, proton pump in bacteriorhodopsin (bR) and transducer activation in phoborhodopsin (pR). It is known that sensory rhodopsins can pump protons in the absence of their transducers. Thus, there should be common and specific features in their protein structural changes for function. In this paper, our r ecent studies on pR from Natronobacterium pharaonis (ppR) by means of low-temperature Fourier-transform infrared (FTIR) spectroscopy are compared with those of bR. In particular, protein structural changes upon retinal photoisomerization are studied. Comparative investigation of ppR and bR revealed the similar structures of the polyene chain of the chromophore and water-containing hydrogen-bonding network, whereas the structural changes upon photoisomerization were more extended in ppR than in bR. Extended protein structural changes were clearly shown by the assignment of the C=O stretch of Asnl05. FTIR studies of a ppR mutant with the same retinal binding site as in bR revealed that the Schiff base region is important to determine their colors.

Inherited peripheral neuropathies (IPN), which are a group of clinically and genetically heterogeneous peripheral nerve disorders including Charcot-Marie-Tooth disease (CMT), exhibit progressive degeneration of muscles in the extremities and loss of sensory function. Over 70 genes have been reported as genetic causatives and the number is still growing. We prepared a targeted gene panel for IPN diagnosis based on next generation sequencing (NGS). The gene panel was designed to detect mutations in 73 genes reported to be genetic causes of IPN or related peripheral neuropathies, and to detect duplication of the chromosome 17p12 region, the major genetic cause of CMT1A. We applied the gene panel to 115 samples from 63 non-CMT1A families, and isolated 15 pathogenic or likelypathogenic mutations in eight genes from 25 patients (17 families). Of them, eight mutations were unreported variants. Of particular interest, this study revealed several very rare mutations in the SPTLC2, DCTN1, and MARS genes. In addition, the effectiveness of the detection of CMT1A was confirmed by comparing five 17p12-nonduplicated controls and 15 CMT1A cases. In conclusion, we developed a gene panel for one step genetic diagnosis of IPN. It seems that its time- and cost-effectiveness are superior to previous tiered-genetic diagnosis algorithms, and it could be applied as a genetic diagnostic system for inherited peripheral neuropathies.

Development of digital technology, which is individualizing and differentiating the world, makes time and space facilitate multi-layering in the contemporary society. It gives a large influence on the contemporary architecture that inducing the visual and spatial experience. Also, It generates new images through the skin of architecture, which implies the contingent and fluid characteristics. These phenomenon show that various parameters are working on the architectural skin simultaneously. Such complexity make the structure of open space and diversity that are homogenized and synchronized. Like this, the architectural skin implies 'multiplicity': qualitative difference which is enable to change and create new images. This characteristic generates instant images changing variously and semantics constantly by the function of skin as a filter. Also, the architectural skin integrates or relocates of relationships between the various information and elements appearing in contemporary society in order to escape the customary relationship between internal and external. Furthermore, the inside and outside of the mixture as a collection of sense has been recognized as one image. This image of mixture consists of one unified continuous integration and extend the meaning of a fluid interface not just surface of the building. The skin of the contemporary architecture is very technical, so its meaning and role is expanded as a complex that exchange interaction. This means that the skin itself has functional elements of the integrated multiple skin to assist. Also it can form a multi-layered relationship and act as a wide range of interfaces depending on the perception of the observer. Therefore the multiplicity of the architectural skin indicates the importance as a boundary that generate images of new life through the sensory perception and implicit force. And it shows potential as the intermediary to try to communicate.

Effects of quality, physicochemical properties and antioxidants in Camembert cheese added with red ginseng powder (RGP) were investigated. Cheese samples were prepared with 0.05%, 0.10%, 0.15% and 0.20% RGP. and then monitored during ripening at $14^{\circ}C$ for 28 d. The pH of the RGP amended treatment groups increased during the ripening period relative to the control (p<0.05). Moreover, the 1,2-Diphenyl-1-picrylhydrazyle (DPPH) was highest in the 0.15% RGP group from 21 d to 28 d. $ABTS^+$ radical scavenging activity was increased just like DPPH as the ripening period passed, 0.10% treatment was highest at from 7 d to 21 d. 0.15% RGP was contents of ginsenosides : 10,999.7 ppm. The Free fatty acids (FFA), controls with 0.15% treatment, while the total fat (TF) and monounsaturated fat (MuSF) were higher in the control than the 0.15% RGP group (p<0.05). The total free amino acid (FAA) was increased in the control, and 0.15% RGP, and control was highest at then 0.15% RGP. The samples had average contents of fat and protein were 29% and 18-20% respectively. Additionally, the $L^*$ value decreased, while the $a^*$ and $b^*$ values increased as the amount of RGP added increased. Sensory evaluation revealed that texture and total acceptability were higher in the control group at 12 d. Although the addition of RGP did not exert a better effect on the ripening of the camembert cheese, but the ripening grade was similar to that of the common camembert cheese, and the additional function of the cheese was reinforced. Functional cheese could be developed.

This article analyzed the recent Korean accessibility standard supporting the people with disabilities. This is the basic study to make the interior environment more comprehensible and safer for the physically handicapped. Researcher selected the interior elements related to the mobility and accessibility for the physically handicapped. Then the '98 Korean accessibility standard code called 'Pyunui Chungjin Pup' were compared with the previous Korean building code and two other guidelines for evaluations. Result showed that 'Pyunui Chungjin Pup' addressed more obligatory items in facilities used by people with disabilities. That contributed to develope the accessible environments and to offer the independent activity in the society for the disabilities. However dimensions of 'Pyunui Chungjin Pup' showed the minimum standard. Also it did not provide the sufficient design considerations to make up the sufficient design considerations to make up the other types of disabilities including sensory limitations, or cognitive function limitations. Hereafter, the quality of accessibility guideline should be raised with further study.

It is necessary for young children to integrate the sense of sight, hearing, touch, etc. for developing their emotion and cognition. Thanks to Information and Communication Technology (ICT) development, young children have more opportunities to use various senses in learning process. However, ICT learning method is more focusing on the sense of sight and hearing, and lacks of integrated recognition and this fact leads to the reason why ICT can not be used as a main education tool. Therefore, this study evaluated the influence of wUbi-Pen(haptic device) on cognition using a computer puzzle program. The results show that young children using a haptic pen have greater intention and performance in object assembly, mazes, picture completion in K-WPPSI test than those of non-using haptic pen. This implies that haptic function should be considered in ICT material and indeed useful in various cognition-related symptoms and diseases.
