The purpose of this study was to compare the casting problem and corrosion behavior in two types of HL Hexed abutments of the Steri-Oss system ; gold/plastic coping and gold coping. The anodic Polarization behavior, the galvanic corrosion between abutments and Type III gold alloys, before and after casting were analyzed, and the crevice corrosion of casting samples was analyzed with the CPPT test and the SEM. The results are as follows : 1. Anodic polarization behavior of samples ; Before casting, gold/plastic coping and gold coping was shown to have a similar corrosion pat-terns. Type III casting gold alloy was shown to have a lower corrosion potential and passivation film. Corrosion potential of the case of gold/plastic coping after casting was higher than that of gold coping, but the region of passivation film for gold/plastic coping was smaller than that of gold coping. 2. Galvanic corrosion behavior of samples ; Contact current density between casting gold alloys and gold/plastic before casting was higher than that between gold coping and casting gold alloy Galvanic corrosion of samples after casting was shown to have similar contact current density 3. Crevice corrosion behavior of samples ; Crevice corrosion resistance of casting sample using gold coping was lower than that of cast-ing sample using gold/plastic coping, and a severe corrosion pattern was observed at the abutment-casting gold alloy interface by the SEM.

Dental implant system is composed of abutment, abutment screw and implant fixture connected with screw. The problems of loosening/tightening and stability of abutment screw depend on surface characteristics, like a surface roughness, coating materials and friction resistance and so on. For this reason, surface treatment of abutment screw has been remained research problem in prosthodontics. The purpose of this study was to investigate the stability of TiN and WC coated dental abutment screw, abutment screw was used, respectively, for experiment. For improving the surface characteristics, TiN and WC film coating was carried out on the abutment screw using EB-PVD and sputtering, respectively. In order to observe the coating surface of abutment screw, surfaces of specimens were characterized, using field emission scanning electron microscope(FE-SEM) and energy dispersive x-ray spectroscopy(EDS). The stability of TiN and WC coated abutment screw was evaluated by potentiodynamic, and cyclic potentiodynamic polarization method in 0.9% NaCl solution at 36.5±1℃. The corrosion potential of TiN coated specimen was higher than those of WC coated and non-coated abutment screw. Whereas, corrosion current density of TiN coated screws was lower than those of WC coated and non-coated abutment screw. The stability of screw decreased as following order; TiN coating, WC coating and non-coated screw. The pitting potentials of TiN and WC coated specimens were higher than that of non-coated abutment screw, but repassivation potential of WC coated specimen was lower than those of TiN coated and non-coated abutment screws due to breakdown of coated film. The degree of local ion dissolution on the surface increased in the order of TiN coated, non-coated and WC coated screws.

Background: The combined induction using two or more agents has a potential benefit that anesthesia could be induced with smaller anesthetic agents with fewer side effects. We studied the effects of co-administration with midazolam and remifentanil on the dose of propofol, the time to loss of consciousness (LOC) and hemodynamics during tracheal intubation. Methods: Sixty patients were randomly assigned to three groups. Group 1 was induced with target-controlled propofol alone. Group 2 received midazolam (0.05 mg/kg) and target-controlled propofol. Group 3 received midazolam (0.025 mg/kg), remifentanil (2 ng/ml) and target-controlled propofol. The time to LOC, the infused propofol dose and the effect site concentration at LOC were recorded. After LOC, rocuronium (0.6 mg/kg) was given and tracheal intubation was performed. The noninvasive blood pressure, heart rate (HR) and bispectral index were recorded. Results: The time and the dose of propofol to LOC were significantly reduced in group 2, 3 than in group 1 (P<0.05). Compared with pre-induction values, mean blood pressure at immediately after intubation was increased in group 1, 2 with no change in group 3. The HR immediately after intubation was significantly increased in all groups compared to the pre-induction values, but the rate of increase of HR in group 3 were significantly lower than those group 1, 2 (P<0.05). Conclusions: The co-administration with midazolam and remifentanil reduces the time to LOC and the dose of propofol. That also attenuates hemodynamics during tracheal intubation under target-controlled infusion of propofol. (Korean J Anesthesiol 2009: 56: 619~23)

문화플랫폼으로서 에스닉타운의 가능성과 새로운 정체성

본 연구는 도시의 문화자원으로써 에스닉타운의 문화적 특성이 어떠한 형태를 지향하고 모색되어야 하는지에 대한 논의를 ‘문화플랫폼’의 개념으로 전개하였다. 에스닉타운은 이주자가 밀집하는 폐쇄적이고 고립적인 공간이 아니라, ‘내부적 문화 다양성’이 구체화되는 공간이다. 문화적 혼종이 새로운 지역의 정체성으로 부각될 수밖에 없는 오늘날 에스닉타운은 이주민과 정주민이 함께 공생하기 위한 새로운 가치와 전략을 필요로 한다. 즉, 해당 지역의 다양하고 복합적인 특성에 걸 맞는 접근과 이해의 틀과 시스템이 필요하다. 이러한 의미에서 ‘지속적으로 다양한 문화수용을 통하여 풍성한 문화적 토대를 형성하는 장<SUP>場</SUP>인 동시에 문화 간 상호교류를 통한 문화의 화학반응으로 새로운 가치관과 문화를 창조하는 장<SUP>場</SUP>’이라는 문화플랫폼의 개념은 에스닉타운의 공간 개발은 물론 에스닉타운 공간의 가치를 발견하고 에스닉타운에 대한 새로운 의미부여와 재구성 등 다변화되는 현대사회에 적합한 개념이라 할 수 있다. 에스닉타운의 문화플랫폼화는 물적, 인적, 관습적, 인식적 차이와 경계를 가로지르는 개방적인 토대 위에서 에스닉타운이 가진 지역의 매력을 발견하고 개발할 수 있는 새로운 시스템으로서 그 기능과 역할을 수행할 수 있을 것이다. 따라서 문화플랫폼은 에스닉타운이 도시의 문화자원으로 나아가 창조도시의 한 구성요소로 작동하게 하는 하나의 모델로서 유효한 의미를 지닌다고 할 수 있다. This thesis mainly covers how the cultural features of ethnic towns known as “Koreatowns” should be formed and be sought as a cultural resource in a city, and so the concept of ‘culture platforms’ is applied to discuss the theory. Ethnic towns are not the closed nor isolated spaces where immigrant workers are gathered but are the spaces where ‘internal cultural diversity’ is specified. We are facing the world that cultural admixture plays an important role as a new identity in a place where immigrants and local residents co-exist. Under the current circumstance, ethnic towns need not only a new value but also a new strategy for all of them to live in harmony. That is, they need appropriate approaches, the frame of understanding, and a system depending on each area’s various and multiple features. In this sense, the concept of culture platforms has two meanings: firstly, it is ‘the place that forms an ample cultural substructure by embracing sustainedly various cultures’ and secondly, it is ‘the place that creates a new identity and a new culture through culture-based chemical reactions.’ And so, this concept is appropriate for the diversifying modern society as it extends not only developing ethnic towns and discovering the value of their space but also giving a different meaning to them and restructuring them. Becoming culture platforms of ethnic towns means that they can function by discovering the attractions of ethnic towns and by developing their spaces as a new system and can play a variety of roles on the open foundation of material, human, conventional, and cognitive differences and boundaries. Therefore, culture platforms have a significant meaning in that ethnic towns can be part of a creative city as a new model.

  The appearance of modern fashion was a bold and innovative expression showing the real phase of modern, society, mass production and consumption mechanical and technological age. It presents images from internalization pursued by art so far to externalization, from personal uniqueness to public universalism, from closed personality to open non-personality. It was found that optional coordination stood out as sup layered style stressing individuality as casual sports boomed and many single clothe turn up from 1960s till 1970s.<BR>  Finally, in the 2000s, androgynous look influenced by pop art sense in the 1960s, neo-hippy and punk in the 1970s, and pop culture in the 1980s was expressed, as new sense, and this is the complicated age of optional coordination, character coordination, cross-over coordination missmatch coordination as free coordination expressing new feelings on all past fashion item.

Background: The aim of this study is to evaluate the effects of local anesthetic distribution on symptoms using ultrasound image after C6 stellate ganglion block (SGB). Methods: Twenty-six patients underwent SGB via an anterior paratracheal approach at the sixth cervical level using 6 ml of 1% mepivacaine. We divided the patients into two groups by local anesthetic distribution using ultrasound image after SGB. In the group `sub`, injected local anesthetic was beneath the prevertebral fascia. In the group `supra`, some of injected local anesthetic was above the prevertebral fascia. The occurrence of Horner`s syndrome, warm sensation on the face and hand, brachial plexus block, hoarseness, and foreign body sensation in the throat were evaluated. The skin temperature of the bilateral thumbs was measured pre and post SGB. Results: The occurrence of hoarseness and the foreign body sensation in the throat was significantly reduced in the group `sub` than the group `supra` (P<0.05). The skin temperature of the ipsilateral thumb significantly increased in both groups compared to the pre SGB values, and the change of the skin temperature significantly increased in the group `sub` than the group `supra` (P<0.05). Conclusions: Subfascial distribution of local anesthetic under ultrasound image after SGB reduces the typical complications. It is more effective in the sympathetic block than suprafascial distribution. (Korean J Anesthesiol 2009;57:579∼83)

Hadong County has established development plans related to a Slow City and has been progressing with them since it was selected as a Slow City in 2009. Considering the development plans are still in progress, we wouldn`t be able to say much about any of them yet. However, people have realized that a Slow City is recognized as a way of tourist development. Also, they have found out that the Korean government has had a leading role in developing these Slow City movements. Nevertheless, there are always some possibilities that we could find out the appropriate ways and directions for a Slow City if the local people take an active part in and get to play a key role for this movement. In this thesis, the appropriate ways and directions will be mainly suggested. This paper doesn`t deal with some superficial ways to attract tourists from all over the country. However, it deals with the strategies and development work, which means how local people want their hometown to change and the changes definitely come from endogenous regional development. This is the primary focus of the thesis. The local development can be greatly improved through democratically discussed talks among local people, and also can be truly advanced when they think themselves as a main group to cope with any problems that they have. Also, this is what we call the basic philosophy that Slow City movements have pursued, which has a lot to do with the local people`s improving the quality of life and inspiring the proud of where they live. In this way, the Slow City movement could revitalize this rural area through endogenous regional development.
