Purpose: To analyse the risk factors for recurrence of hemangiomas in extremities after surgical treatment and to compare with those of trunk. Materials and Methods: 120 cases of hemangioma with surgical treatments from June 1998 to September 2009 were analysed. 53 cases with surgical treatment on trunk in the same period were set to be the control group. We analyze several factors: age, location, site, size, histologic types and correlation between recurrence and each risk factor using logistic regression analysis. Results: Recurrence rate was 11.7% in extremities and 9.4% in trunk. There were no correlation between recurrence and age, site, size, histologic type. But, there was stastically significant correlation between recurrence rate and location, especially hand, forearm, feet in extremities and head and neck in trunk. Conclusion: Recurrence after surgical treatment of hemangioma is highly prevalent in anatomical location such as, hand, foot and forearm those are difficult to achieve complete resection because of close to neurovascular structures. Careful observation should be needed owing to incomplete resection can occurs recurrence.

As digital dentistry technology is being developed, it is being used in various ways. This case covers how digital dentistry technology is being applied on the treatment of patients with loss of vertical dimension due to worn dentition and multiple loss of teeth. The loss of vertical dimension was carefully assessed and recovered, and implants were placed with surgical guides, designed considering the final restoration. The movement of the mandibular was measured with the electronic instrument for recording mandibular movement. Wax-up process was done with Naturgemäße Aufwachs-Technik (N.A.T.) and Natural functional reconstruction (N.F.R.). It was scanned, and the provisional restoration was fabricated using Computer-Aided-Design/Computer-Aided-Manufacturing (CAD/CAM) technology, and the adjustment process was done at the clinic to meet with the satisfaction both functionally and esthetically, and then, using double scanning and CAD/CAM technology, it was carried out as a final restoration. As a result, the patient obtained satisfying results, utilizing the benefits of digital dentistry technology and traditional methods.

Radiopharmaceuticals are drugs that contain radioisotopes and are used in the diagnosis, treatment, or investigation of diseases. Radiopharmaceuticals must be manufactured in compliance with good manufacturing practice regulations and subjected to quality control before they are administered to patients to ensure the safety of the drug. Radiopharmaceuticals for administration to humans need to be sterile and pyrogen-free. Hence, sterility tests and membrane filter integrity tests are carried out to confirm the asepticity of the finished drug product, and a bacterial endotoxin test conducted to assess contamination, if any, by pyrogens. The physical appearance and the absence of foreign insoluble substances should be confirmed by a visual inspection. The chemical purity, residual solvents, and pH should be evaluated because residual by-products and impurities in the finished product can be harmful to patients. The half-life, radiochemical purity, radionuclidic purity, and strength need to be assessed by analyzing the radiation emitted from radiopharmaceuticals to verify that the radioisotope contents are properly labeled on pharmaceuticals. Radiopharmaceuticals always carry the risk of radiation exposure. Therefore, the time taken for quality control tests should be minimized and care should be taken to prevent radiation exposure during handling. This review discusses the quality control procedures and acceptance criteria for a diagnostic radiopharmaceutical.

Most of studies on the press during the period of Japanese occupation in Korea have focused on the activities of newspapers in 1920s. These past studies didn't examine the whole process of change of the press under the Japanese occupation in Korea. Thus, this study tried to investigate the change of the tenor of Korean newspaper editorials on the ruling policies during the end of the colonial period in Korea as a part of attempts exceeding the limit of past studies. After the outbreak of the war between China and Japan in 1937, the Korean newspapers were full of stereotyped editorials resembling in a way official gazette. Dong-A Ilbo and Cho-Sun Ilbo represented the purpose of the war was to emancipate Asian countries from Western imperialist countries and to establish the peace of the Asia. Simultaneously, two newspapers played an important role in assimilating the Korean people into the Japanese and mobilizing them to the war, The tenor of these editorials was affected by intensified control over the press and the change of the consciousness of journalists. In conclusion, these newspapers had a harmful influence on the Korean people as a weapon to the movement to organize and mobilize them. Therefore the interest for researching on the pro-Japanese press should be taken in view of 'resistance' and 'collaboration.'

To investigate the effect of the cell wall on the pigmentation and branching in Aspergillus nidulans, ultrastructure of cell wall in suppressor mutant of the null pigmentation (SU-NPG, SU602) has been examined. Scanning electron microgrphs (SEM) revealed that the most outer layer of conidia wall peeled off in SU-NPG on day 6 from the complete conidiation. They also showed that hyphal growth and branching were not well developed in SU-NPG. Transmission electron micrographs (TEM) showed that the plasma membrane was not crenulated and the hyphal wall was thick in SU-NPG. These results indicated that the ultrastructure of cell wall in SU-NPC might be modified. Cytochemical analysis showed that the cell wall in SU-NPG was differentiated into Cl, C3, C2 and C4 layer in conidia and H1, H3, H2 and H4 layer in hyphae. C3 layer and H3 layer existed in SU-NPG. The increment of the diameter in SU-NPG hyphae might be caused by the thickness of H3 layer. These results suggest that SU-NPG may have an immature but the differentiated structure for the pigmentation in cell wall.

As the globalization become the main stream in our world, there is no exception also on the cultural section. And we are En the midst of this rapid transition. In the case of advertising market, we opened to those agencies in abroad in the early year of 1990 and now completely opened. On this thesis, the multinational corporation advertising was studied and researched by empirical case study. The main topic is the value expression in the advertising creativity viewed on the cultural level. The multinational corporations that have an eminent, powerful brands produces much of goods wend widely with their powerful brands and extend their marketing activities to abroad. For example, those non-alcoholic beverages, pharmaceutical products, cosmetics, electronic appliances, vehicles, sports shoes, clothes are their main exports, and they broaden the product category, market size to the global market. They also use an expert marketing skill accumulated for a long time. The advertising activities is one of the useful method to extend their global market abroad enhacing continuously brand value. And much of the multinational corporation's advertising are suspected of negative effects that advertisements works on a tool which curies so called uniformed ideology - various ruling ideology - with commercial messages. These advertising affect an developing country's moral value, life style, social value, and others. And they weaken those developing country's unique tradition, culture by putting their own ideology. Those who have a critical position on the advertising activities have been careful in judging it's effects. The result of this study which of the value system is expressed in the multinational corporation's advertisements are; First, the self - esteem value is classified by western value, and it was founded out much more in the domestic corporation's advertisements then multinational ones. Second, the security value system is classified by western value system, and it's outcome was much the same as former one. Consequently, the multinational corporation's advertisements have less of an western value expression relative to korean advertisements. Those outcomes may infer that the multinational corporations prefer to an compromise creative strategy in korea for avoiding cultural conflicts.

This paper argues that the establishment of the Kaohsiung Export Processing Zone (KEPZ), the first EPZ in East Asia, is a compromise of cold-war geopolitical economy in the 1960s. The KEPZ is part of the liberalization policy advise of the US Aid agency which intended to push the KMT (Kuomintang) government to downsize the nationalized sectors and foster private enterprises and encourage foreign investments. However, the KMT state hesitated to embrace the advice wholeheartedly but was forced to implement selectively the policies. To meet the compromise between liberalization and control, the KMT government takes advantage of the KEPZ to grab the geoeconomic opportunities emerging from the new international division of labor in the 1960s without losing the geopolitical support from the US. The idea that zoning as a space of compromise would provide a subtle re-examination of the rise of the KEPZ which is conventionally explained by the functionalist arguments such as increase of employment opportunities, foreign investments and export by the far-sighted developmental state.

The documentation of a city can never be complete with only the documentation of the administrative domain, and requires that of its citizens, who are living in the city in different ways. This study attempts to present the documentation of the memories of the citizens, which either have never been produced or have been damaged and thus are difficult to be collected. From the Archival Activist point of view, this study suggests documentary as its research method, in order to leave trace of various experiences of Seoul, which are not recorded in document but are rooted in its people's memories and their daily lives. Documentaries are characterized by their narrative. This can be somewhat arbitrary, but it is due to their narrative that this study suggests documentaries, rather than oral statements, as a new form of method. While, due to its self-historicality, oral records are subject to producing redundant or irrelevant memories, documentaries enable the documentation of data relevant to the topic of collection. First, the study presents the narrative-based archiving, which is the same method of collection suggested by Seoul Metropolitan Archives, and then explores the role and significance of documentary archiving. It further presents the conditions in which documentary archiving is required in the context of narrative-based collection. The study presents the planning and implementation of documentary archiving and introduces one of the three documentaries produced by 2019 Seoul Archiving Project.

The issue of security on the Korean peninsula is facing the greatest upheaval in 2018 with the inter-Korean summit and the US-North Korea summit. North Korea has pursued the parallel policy developing military and economic at the same time. However, North Korea is changing its route to give up nuclear weapons and focus on the economy through summit talks. Since the change in North Korea is similar to that of Libya in the past, it is necessary to analyze why North Korea is trying to abandon its nuclear program and how the process is flowing compared to the case of Libya. The Libya model was constructed and analyzed in terms of international and domestic perpectives and recognition of the situation by leadership. North Korea's nuclear policy was evaluated based on the Libya model. The nuclear development of Libya and North Korea has caused diplomatic and economic pressures from the international community and ultimately led to instability of the regime. Two countries have tried to abandon nuclear program in order to solve the instability of the regime, also gain the economic reward insead. Libya took economic benefits and secured some of the stability of the regime, but the regime collapsed under the wave of democracy due to the influx of foreign capital and ideas. North Korea will seek diplomatic and economic gains with the example of Libya, but will try to limit as much as possible the culture of democracy and the full opening that can be incidental.
