This paper want to examine how Gwanghwamun and its surrounding areas work in the cinematic spaces for Korean films of the 1950s-2010s. First, in Korean films of the 1950s-1960s, Myeong-dong(Namchon), Bukchon, Seochon, and Dongchon are the primitive, perceptual, existential spaces that show the underground world and tragic pathos in the splendid city through intense desires and fatal frustration, the shadows and conflicts of modernization. Second, in Korean films of the 1970s-1990s, Myeongdong·Jongno(Namchon·Bukchon), Seochon and Dongchon are the perceptual, existential spaces that show public revenge and private alienation through the dichotomy of freedom/evil and the dichotomy of wealth/poverty. Third, in Korean films of the 2000-2010s, Gwanghwamun(Seochon), Bukchon, Namchon, and Dongchon are the perceptual, existential spaces that show civil society ethos and gloomy requiem through national agendas, resistance movements, desires and losses, miserable reality and death.

The loss of posterior support and the abnormal jaw relation can cause pathologic findings. If deep bite patients with multiple missing teeth, can not have the stable posterior contact, the mandible moves posteriorly, and consequently the overjet and overbite get worse. And when the mandibular irregular occlusal plane is corrected, it is easier to have the bilateral balanced occlusion with the maxilla. So the treatment goal is to give proper posetrior support and establish appropriate anterior guidance, and ultimately provide improved mastication and esthetics recovery. In this case, a 68 year old man, having deep bite without posterior support was evaluated by the vertical dimesion decision flow-chart. An available prosthetic height, anterior occlusal relation such as overjet, overbite and the esthetic part such as facial height and the cephalometric analysis are the factors to be considered.

The patient in this case was an 80-year-old female who had lost #16, 13, 26, 37, 36, 35, 44, 45, 46, 47 teeth. The patient showed loss of posterior support, loss of vertical dimension of occlusion, and deep anterior overbite. Her chief complaint was esthetic and functional discomfort. She wanted to restore normal facial aesthetic shape and masticatory function through prosthetic treatment. Clinical evaluation, radiographic examinations, and facial and oral analysis were performed. Interocclusal rest space was excessive than the average. Distance between labial vestibules and zenith of central incisors, and lower facial ratio were below the average. Taken together, occlusal rehabilitation was determined through increasing 4 mm of vertical dimension on premolars. In this case, a patient who lacked restoration space with deep bite in the anterior region due to loss of the posterior teeth support restored a stable occlusal relationship and harmonious anterior and lateral guidance through fixed and removable prosthesis with increased vertical dimension.

The aim of this study was to retrospectively analyze the effects of pulp treatment on exfoliation of primary teeth and its related factors. In this study, 167 teeth of 97 patients aged 6 months to 12 years who were treated with pulp treatment at Dankook Dental Hospital were selected, and information related to pulp treatment and tooth loss was collected. The included subjects were 72 primary anterior teeth (43.1%) and 95 primary posterior teeth (56.9%), of which 56 were males (57.7%) and 41 females (42.3%). The mean follow-up period was 106.1 ± 38.7 months, and the mean age at pulp treatment was 34.8 ± 15.4 months for primary anterior teeth and 69.1 ± 25.1 months for primary posterior teeth. Unilaterally pulpectomized teeth were significantly exfoliated earlier than the same tooth on the opposite side (p < 0.05). Also, in the case of teeth with periapical lesions, despite pulp treatment, the probability of extraction due to infection has been increased on primary anterior teeth (p < 0.05), but not on posterior teeth (p > 0.05). Pulpectomized teeth were lost earlier, an average of 7.8 months for primary anterior teeth and 8.5 months for primary posterior teeth. Early loss of the primary tooth can lead to space loss and premature eruption of the successor, so this can be considered when planning or performing treatment of the primary tooth.

This study is to suggest the direction of the spatial change of the university library based on the trend of the spatial change in the university libraries and a survey on the perception of the librarians. For this purpose, the characteristics of the spatial change of the university libraries from 2000 to 2020 were analyzed, and the problems of the spatial change of the university libraries were identified through a survey. As a result of the survey, there was a total of 99 spatial changes in the university libraries nationwide over the past 20 years, including new construction, extension and remodeling. In recent years, it was found that due to the university's budget tightening policy, the university libraries focus on remodeling rather than new construction or extension. The characteristics of the spatial change were analyzed as follows. First, the resting areas have been expanded in the libraries. Second, The libraries are in pursuit of pleasant and comfortable atmosphere. Third, the libraries aim to establish an innovative and creative space. All these changes have been made in order to accommodate the requests of users and increase the number of users. It was also found that spatial change has advantages in these two points: providing various spaces and increasing the number of library visitors. On the other hand, spatial change has the problems such as the increased cost of maintaining the facility and the lack of management manpower. Additionally, a few more problems of spatial change are pointed out: first, spatial change only reflects the trend of the times without making a big change in the services and the actual value of the university library. Second, it has made university libraries standardized losing each library's own characteristics. This study suggests that the spatial change of the university library should secure the distinctiveness of the university library, accommodate various changes, and aim for the symbolism that can prove the value and existence of the university library.

The history of modernization of Korea is divided into two folds of the colonial era in the 20's and the economic development era in the 60's. Most of the spaces built in the process of modernization were public spaces developed by the drive of the government. These spaces of modernization are functionality-oriented public places of production and at the same time, and they are the spaces of national power to symbolize the identity of national authorities. Along with changes in the society, modern spaces were reduced down to monument buildings without functionality and this requires new definition to renew the identity of modern spaces. Small stations, power plants, mines, warehouses, abandoned factories, and etc... the study has paid attention to the process of changing thought, one of the main characteristics of modernization, the relations of modern concepts projected in the spaces, framework of modern society, and placeness in the process of framework building and relations of people in the spaces with video records on the process of rebuilding new identity of modern spaces and memories of the spaces. The relations of modern spaces and memory were explored in < Seoul Station > while the relations between modern spaces and records and place identity were explored in < Onyang Folk Museum > and < Okpo Shipyard > respectively. In the relations between space identity and memory in each space, the ironic relations of power in modern spaces (placeness) and personal narrative (memories) were explored with oral narrative and video footage.

The term 'impaction teeth' is used to designate a tooth which remains unerupted in jaw beyond the time at which it should normally be erupted. Most cases of impacted teeth reported in the literature are permanent teeth. The impaction of primary teeth occur rarely whereas impaction of second primary molars is more numerous than all other impactions. Failure of eruption of primary teeth may cause a number of complications, such as interference with development and eruption of successive permanent teeth, malocclusion, cystic change of tooth follicle. The clinican should consider the various treatment option available (a) No treatment and observation, (b) surgical extraction (c) space regainer. Proper treatment plan should be established after thought consideration of impacted tooth and it's relation with successive permanent tooth.

The mandibular buccal frenum becomes a problem when its attachment is too close to the marginal gingival. Heavy buccal frenum mucogingivally results in insufficient attached gingiva, inadequate vestibular depth and also difficulty in eruption of mandibular premolar. The aim of this study is to demonstrate the effectiveness of apically positioned partial-thickness flap as adequate method in order to remove heavy buccal frenum and expose impacted teeth. The author presents the case of a 12-year-old boy. He had problems that was prolonged eruption of #34, #35 due to high pull buccal frenum. After space regaining for normal eruption of #34, #35, we performed apically positioned partial-thickness flap on #34, 35 area. As a results, we confirmed that eruption of #34, #35 has been processed normally And vestibular depth, position of buccal frenum and width of attached gingival was within a normal range. Decrease in muscle pull, adequate width of attached gingiva and increased vestibular depth can be expected from this treatment.

Delayed eruption disorders caused by systemic or local conditions are mostly found during childhood and can be treated with orthodontic forced eruption. When the disorder is not found nor treated during childhood, however, orthodontic eruption might become a difficult option while prosthodontic restoration can be considered as an another option. Considerations for the prosthodontic treatment plan include the extent of tooth loss, interdental mesio-distal space and interarch space, and age of the patient. In this case report, oral rehabilitation of the patient with delayed eruption disorder through zirconia partial fixed prostheses for both maxilla and mandible was performed.
