Supracricoid partial laryngectomy (SCPL) with cricohyoidoepiglottopexy (CHEP) or cricohyoidopexy (CHP) involves the removal of the whole thyroid cartilage, both true and false vocal cords, the ventricles, and the paraglottic spaces, sparing the cricoid cartilage, hyoid bone, and at least one functional and mobile cricoarytenoid unit. Reconstruction is performed by suturing of the cricoid cartilage up tightly to the hyoid bone, so trachea-releasing procedures are needed to prevent leakage at anastomosis site. In case of advanced tranglottic cancer invading tracheal tracheal wall, we need to perform additional circumferentrial circumferential tracheal wall resection. However, when we perform SCPL, circumferential resection of tracheal wall is limited because SCPL procedure itself needs releasing of tracheal length. We report a case of advanced transglottic cancer involving tracheal wall treated with induction chemotherapy and SCPL including tracheal wall resection with reconstruction of tracheal defect by sternocleidomastoid muscle flap covered with skin graft.

Characteristics and roles of protease released during the germination of Dictyostelium discoideum spores were investigated. When geat activated, the spores germinated, progressively releasing the protease into the extracellular medium. The protease activity exhibited high at pH 2.5. When cyclogeximide was added to culture, complete germination (emergence) and protease release were stopped. Addition of purified nonspecific protease to culture speeded up germination. These results suggest that excreted protease may play a role in removal of the spore wall.

Purpose: The purpose of this study is comparing the efficiency of debris removal of passive ultrasonic irrigation depend on different protocols. Materials and Methods: Forty-eight mandibular premolars were randomly divided into 2 groups depend on vibration power (Weak and Strong, n = 24). And then two groups were subdivided into 3 groups depend on the number of times that PUI used (1, 2 and 3, n = 8). After standardization, teeth were split into two halves. On the wall of one half of root canal, three depressions were cut at 1, 3 and 5 mm from the apex and in the same way two depressions were cut on the other half of root canal at 2, 4 mm from the apex. Each depression was filled with mixture of dentine and NaOCl. After irrigation, images of the root canal wall were taken, and then the amount of remaining dentine debris was evaluated. Results: There was no significant difference between weak and strong power of vibration groups. Weak vibration groups did not show significant difference depend on the different number of times PUI used. But in the strong vibration groups, twice and three times used groups show better removal efficiency. Conclusion: The removal efficiency of dentine debris is not significantly different depend on the power of vibration. And multiple use of PUI could have better irrigating effects at the apical third area in the strong vibration group.

This research aimed to provide a scientific methodology for removing white and black/brown coloured stains on the wall paintings of tombs of Jinpari No 1 and No 4. in the Democratic People's Republic of Korea. For the analysis of chemical composition of stains of the samples from the wall paintings, a microscope and SEM/EDX were used. The analysis confirmed that the fomula of white coloured stains should be $CaSO_4$ or $CaCO_3$ and the black/brown coloured stains should be $CaSO_4$ or $CaCO_3$ with soil deposition. Because of the difficulties of testing several cleaning solutions on sample patches of large area of the painting, the author considered a risk-free cleaning solution as being the most appropriate one, with Ammonium bicarbonate and Anion exchange resin showing satisfactory cleaning effect without visible side effects. For the removal of dense layer of stains, the research suggested that physical cleaning should be followed by applying a cleaning solution.

The vernacular houses with 田-shaped floor plan at Gangreung have been played important roles in tracing the vernacular living cultures including housing life. But due to the adoption of convenient facilities in vernacular housing lives caused by modernization and urbanization, many changes and transformations have happened at residential space of vernacular houses. This thesis targets to extract basic data to prepare and prevent various problems in process of renovation, extension and function change as installing housing life facilities, and to identify the changes and transformations of them to prepare the proper balances between their original form preservation and residents' convenience living. The results are as follows. The inner wall removal of rooms, the fuel change of cooking and heating, the leveling change of kitchen floor made possible the sedentary lifestyles. And its residential rooms were transformed from two row to one row by inner wall removal, the fuel heating change, the heating method change and the heat insulating materials. The residential extension materials were changed from the traditional materials such as soil, wood, etc to the modern materials such as cement block or brick, sandwich panel, etc. And the modern materials were used and attached to widen residential spaces to the vernacular house because of the easiness of execution. So, it is necessary for 田-shaped floor plan vernacular house owners to distribute printed execution guide book to prevent and minimize the various problems to be shown by extension, renovation and function change.

This study focuses on the characteristic of community making in urban areas and the implications in the case of Samduck-Dong, Daegu City. This study observed the geographic feature of Samduck-Dong, the background and process of community making and the citizen's interests and respondence. Samduck-Dong is located near CBD of Daegu and surrounded by useful places and facilities. This area is perceived as an attractive housing environment. As the commercial function is increased and the studio type house for rent, so called one room, is constructed, it is anticipated to get some trouble of building up community. The program of community making in Samduck-Dong, started from wall removal, is attempted diversly now. The places in relation to community making became a representative character of Samduck-Dong. However, there is problems of citizen's participation and the appreciation sharing about the contents and scale of community making.

B-mode ultrasound is being used to assess carotid atherosclerosis in epidemiological studies and clinical trials. Recently the interpretation of measurements made from ultrasound images has been questioned. This study examines the anatomical correlates of B-mode ultrasound of carotid arteries in vitro and in situ in cadavers. Twenty-seven segments of human carotid artery were collected at autopsy. pressure perfusion fixed in buffered 2.5% gluteraldehyde and 4% paraformaldehyde and imaged using an ATL UM-8 (10 MHz single crystal mechanical probe). Each artery was then frozen, sectioned and stained with van Gieson or elastin van Gieson. The thickness of the intima. media and adventitia were measured 'to an accuracy of 0.01 mm from histological sections using a calibrated eye graticule on a light microscope. Shrinkage artifact induced by histological preparation was determined to be 7.8%. Digitised ultra sound images of the artery wall were analysed off-line. The distance from the leading edge of the first interface ($LE_{1}$) to the leading edge of the second interface ($LE_2$) was measured using a dedicated programme. $LE_{1}$-$LE_{2}$ measurements were correlated against histological measurements corrected for shrinkage. Mean values for the far wall were: ultra sound $LE_{1}$-$LE_{2}$ (0.97 mm, S.D. 0.26), total wall thickness (1.05 mm, S.D. 0.37), adventitia (0.35 mm, S.D. 0.16), media (0.61 mm, S.D. 0.18). intima (0.09 mm, S.D. 0.13). Ultrasound measurements corresponded best with total wall thickness, rather than elastin or the intima-media complex. Excision of part of the intima plus media or removal of the adventitia resulted in a corresponding decrease in the $LE_{1}$-$LE_{2}$ distance of the B-mode image. Furthermore. increased wall thickness due to intimal atherosclerotic thickening correlated well with $LE_{1}$-$LE_{2}$ distance of the B-mode images. B-mode images obtained from the carotid arteries in situ in four cadavers also corresponded best with total wall thickness measured from histological sections and not with the thickness of the intima plus media. In conclusion, the $LE_{1}$-$LE_{2}$ distance measured on B-mode images of the carotid artery best represents total wall thickness of intima plus media plus adventitia and not intima plus media alone.
