The objective of this study is to detect a inter-tidal topographic change in a decade. Waterline extraction is a one of widely used method to generate digital elevation model (DEM) of tidal flat using multi-temporal optical data. This method has been well known that it is possible to construct detailed topographic relief of tidal flat using waterlines In this study, we generated two sets of tidal flat DEM for the southern Ganghwado. The DEMs showed that the Yeongjongdo northern tidal flat is relatively high elevation with steep gradients. The Ganghwado southern tidal flat is relatively low elevation and gentle gradients. To detect the morphologic change of tidal flat during a decade, we compared between early 1990's DEM and early 2000's DEM. Erosion during a decade is dominant at the west of southern Ganghwado tidal flat, while sedimentation is dominant at the wide channel between the southern Ganghwado and Yeongjongdo tidal flats. This area has been commonly affected by high current and sedimentation energy. Although we are not able to verify the accuracy of the changes in topography and absolute volume of sediments, this result shows that DEM using waterline extraction method is an effective tool for long term topographic change estimation.

Background and Objectives : Despite of high prevalence, Tinnitus remains obscure because the cause and mechanism is poorly understood. In the absence of a suitable animal model, past investigations tool place in humans. Recently, the animal model with sodium salicylate ototoxicity is broadly used because of its reversibility. Balyangtongum-Tang had been used clinically to treat tinnitus and other hearing problems. We investigated the effects of Balyangtongum-Tang on cochlear morphologic change induced by sodium salicylate ototoxicity and were to find out its therapeutic effects on ototoxicity in rat model. Materials and Methods : Healthy ten Sprague-Dawley rats were divided into normal(2), control(4) and sample(4) groups. The sample group was given extract of Balyangtongum - Tang(1cc/100g) once a day for 4 days. After 3 hours when last medication were given, the sample and control groups were injected intraperitoneally with sodium salicylate(500mg/kg). We observed the cochlear morphologic changes of rats every 1, 2, 3 and 5 hours after injection. Results : The electron microscopic finding of outer hair cell shows some changes in the curticular plate and cytoplasm. Some vacuoles were found in the control and sample groups. Vacuolization in the curticular plate and cytoplasm of the sample group after 3, 5 hours were similar to the control group. But the curticular plate of the sample group after 1, 2 hours did not from vacuole. On the other hand the control group after 1, 2 hours formed vacuoles in the curticular plate. Light microscopic findings of cochlear duct in control and sample groups didn't find any difference. Conclusion : The results suggest that extract of Balyangtongum-Tang reduces the morphologic changes induced by sodium salicylate ototoxicity and the effects are remarkable in frist 2 hours. However the effective times are different with previous studies, it seems to due to the difference of tolerance and sensitivity of laboratory animals.

The purpose of this study is to provide beauticians with the fundamental material for them to use effectively heat permanent wave and satisfy their customers. It carried out an experiment with hair of a woman in her late twenties to investigate the change of physical and morphologic characteristics by its water content when performing heat permanent wave. It evaluated the water content as 0g, 1g, 2g, 3g and 4g respectively when performing the heat permanent wave on hair, then it compared and observed the wave type, tensile strength and elongation for its physical change also observed the morphologic change by scanning electronic microscope and transmission electronic microscope. The result of experiment on the physical specificity revealed that the wave was the most ideal when the water content was 2 g. The material with much water content made wave but the result was not satisfied. In the case of hair with water content of nearly 0g didn't make wave. In terms of tensile strength and elongation, the tensile strength was generally reduced as hair was damaged, on the contrary, the elongation was increased. It observed the change of morphologic characteristic and got the result that the damage on hair cuticle was deepen as its water content was decreased. It also showed the result that damage happened on hair cuticle more than hair cortex with the observation of fine structure on hair section by transmission electronic microscope. Generally chemical treatment damaged hair. Under consideration of this aspect, the ultimate goal of this thesis is to minimize the damage of hair caused by chemical treatment and get the satisfaction on the hair style. The result of experiment presented that the hair showed the best result when its water content was 2 g.

Since the late of 20C, contemporary fashion have becoming enlargement between role and function of fashion through the combination and the deconstruction among various different spheres. Because multi-functional and trans-formal fashion transforms and extends original space and role toward any other fields through the morphologic and structural combination, this has been freed form the representational function pursuing more simple morphologic imitation, and becomes to change the space that is able to 'becoming' of Jill Deleuze. This paper intends to make a comparative study between the representation phenomenon about simple morphologic imitation of existing fashion design, and the becoming phenomenon of fashion focused on the change toward any other different object. This studies' conclusion as follows. 1) First representation imitates a lot of nature forms that are able to be restored any fixed form and picture. 2) Second representation is the representation of representation that re-imitates imitated object and art work. 3) Ontalogical becoming is classified with depaysement, self-presentation of fashion, morphing, and becoming the nature as a element.

Background and Objectives: Tinnitus is on the increase due to the increase in the elderly population, industrial pollution and noise pollution. This symptom is especially marked in patients with a hearing problem and the relationship between cause, mechanism and treatment is poorly understood. The characteristics of tinnitus and other hearing problems are well brought out using an animal model with salicylate ototoxicity. Therapeutic effects of Uncariae Ramulis and Testudinis Plastrum were expected in tinnitus and hearing problems; therefore we experimented on an animal model with salicylate ototoxicity. Salicylate is one of the most commonly prescribed drugs, although it has been recognized that salicylate induces hearing loss and tinnitus reversibly. The purpose of this study was to find the therapeutic effects of this by the morphologic study using salicylate ototoxicity. Materials and Methods : Twelve healthy Sprague-Dawley rats were divided into three groups: normal, control and sample. The sample group was treated with the extract of Uncariae Ramulis and Testudinis Plastrum (1cc/100g, once a day for 6 days). Then, to induce the salicylate ototoxicity in the control and sample groups, rats were injected intraperitoneally with sodium salicylate (500mg/kg). We observed the morphologic changes in the cochlea of the rats every 2, 3, 4 and 5 hours after injection. Results : The outer hair cells showed marked changes. Vacuolization formed in the cuticular plate and the endoplasm of the control group. The endoplasm and the cuticular plates of the sample group after 2 hours were similar to the control group, but the cuticular plates of the sample group observed after 3, 4 and 5 hours were not similar. Conclusions : The results suggest that an extract of Uncariae Ramulis and Testudinis Plastrum has therapeutic effects on an animal model with salicylate ototoxicity.

This study was evaluated the metabolic, physiologic and histologic effects of myocardial protection of verapamil[isoveratril]on isolated rat hearts to 90 minutes of ischemic arrest. Heart was perfused with a modified Kreb’s Henseleit bicarbonate buffer with glucose and arrested with retrograde coronary perfusion by glucose insulin[GI], potassium and verapamil. Mean aortic systolic pressure, heart rate, coronary flows were measured and morphologic changes were examined during working heart perfusion. Perfusion and arrest were controlled four groups subjected 60 isolated rat hearts. Four groups hearts reperfused during 40 minutes after 90 minutes global ischemia for physiologic recovery. 15 hearts of four groups were assayed to histological morphologic changes. GI treated hearts recovered less than 28% of function and changed more than 80% of mitochondria of control group. Verapamil hearts[0.2, 0.1 gm/kg] recovered more than 88% of function and permitted the maintenance of continuous cellular level of Serum Glutamic Oxalaxetate Transaminase[SGOT], but declined 28% of Phosphate Kinase[CP], GI treated heart showed widespread evidence of extensive damage of mitochondria. The damage was that interstitial huge edema are present and there was contraction band formation within the swollen cells. The verapamil and potassium group were not found morphologic change compared with control group. Their functions were shown that metabolic and physiologic action of verapamil-group lasted 20 minutes longer than potassium group.

Allergic contact dermatitis is a common skin disease resulting from specific immunologic to topically applied various allergen. After Dinitrochlorobenzene (DNCB) secondary sensitization, the ICR mice administered Rhemanniae radix extract (RRE) was observed to ascerstain the effect of RRE on allergic contact dermatitis. Purpose of this study was to investigate contact hypersensitivity assay, abdominal skin morphologic changes. Including mast cells and cell-surface glycoconjugates. The change of interleukin 2 (IL-2) receptor (CD25R). ICAM in abdominal skin, lymph node of inguinal region, and electro microscope-morphologic changes of abdominal skin. The results of this study were as follows: 1. The contact hypersensitivity assay, the ear swelling in the RRE had lesser probability than in the ACD Group. 2. In the general morphologic change of skin, hyperplasia of keratinocytes, distribution of vasculogenesis and epidermal lymphocytes infiltration were decreased in the RRE group compared with the ACD group. In epidermal basal layer and prickle layer, cell damage was decreased in the RRE group compared with the group painted with ACD. 3. MasT-cell in dermis was decreased in the RRE group compared with the group painted with DNCB. 4. Distribution of interlukin-2 Receptior positive cell and ICAM positive cell in dermis was decreased in the RRE Group compared with the ACD group. 5. Distribution of helper T-lymphocyte and cytotoxic T-lymphocite in inguinal nodes was decreased in the RRE group, and was observed well in paracortical area and cortical cord. 6. Distribution of apoptotic cell was appeared in the RRE group compared with the ACD group, in skin, dermis. in inguinal nodes, paracortical area observed well. With above results, the restarint of immunosuppression occuring in Allergic contact dermatitis is resulted in the slow progress the effect of Allergic contact dermatitis, and it is thought that ithis fact has a series of relation with apoptosis.

Bacillary is the most common form of H. pylori observed during human infection. However, it is known that the morphology change of H. pylori from bacillary to coccoid can be occurred with a response to the environmental stresses such as the nutrient depletion, accumulation of toxic metabolites, pH alteration, and exposure to antimicrobial agents. The coccoid form of H. pylori, which is viable but non-culturable in vitro, seems to be the major cause of antibiotic resistancy and high reinfectability of H. pylori. In this regard, we studied the environmental factors that can induce the morphological change in vitro of H. pylori, and the change of fatty acid composition of plasma membrane. The morphological change from bacillary to coccoid could be observed with the depletion of nutrients, pH variation and reactive oxygen species added in the culture media. This morphologic conversion was paralleled by a dramatic decrease in unsaturated fatty acids and an increase in saturated fattv acids of plasma membrane. The change in composition of membrane fatty acid seems to be a kind of protection mechanism of H. pylori against these environmental stresses.

This thesis aims to investigate the morphologic relationship among the neckline, collar, and hair style, in which the width and height were measured by selecting the representative costumes from 16th to 19th centuries. The pieces of 170 pictures selected by fashion experts were cut in the same condition, with the part of the end of shoulder, head, and chest all placed on the equal level. The products were directly measured by a team of 3 specialists for verification of this study, of which results were calculated into average. The values of output were categorized into the unit of decade and finally into a graph of variation, in which the trend and relationship were evaluated according to the width and height. In 16th century, the width and height of the neckline were inversely proportional to those of hair style, while those of collar were proportional to those of hair style. In 17th century, the width and height of the hair style were proportional to those of neckline and collar. In 18th century, those of the neckline were inversely proportional to the hair style, with no collar found. In 19th century, the width of the neckline and collar were proportional to that of the hair style, while the height of the neckline and collar were inversely proportional to that of the hair style. The analysis of the morphologic relationship among neckline, collar, and hair style resulting from this study revealed that the change of the hair style took place corresponding to those of neckline and collar. Generally, the width of the hair style was found to be more resistant to change, compared to those of neckline and collar that were more susceptible. The height of the neckline was more resistant to change, compared to those of the hair style and collar presenting their frequently fluctuating height. Conclusively, the factor of height rather than that of width showed more dominant proportions, because the various forms of the collar and hair style evolved in terms of the height rather that width, relative to that of the neckline.
