This paper offers a comprehensive view of international risk sharing and of related policy issues from the perspective of the European Union. The traditional analyses contemplate three risk-sharing channels: the capital markets channel (through cross border portfolio investments), international transfers and the credit markets channel (via savings). Comparative analyses reveal that, on average, about 80% of the shock remains unsmoothed in Europe while only about 18% of the shock is transmitted to consumers within the US. From aggregated figures, there is space for improving, particularly, the cross-border investments channel in Europe. In this sense, the completion of the Banking and Capital Markets Union are expected to boost risk sharing across European member states. We also review new additional issues usually not contemplated by the traditional literature as depreciation, migration and the role of sovereigns and two new additional channels recently considered in the literature: government consumption and the real exchange rate. Finally, we also examine recent analysis related to the geographic distribution of risk sharing.

This present study focuses on Franco's censorship and its influences in the works of Carmen Martín Gaite and Miguel Delibes. We know that from the years 1940's to 1970's a very harsh censorship existed in Spain. But the authors of those times were not completely obedient to the power of the Regime. Some authors attempted to find a new way to present his novels. In fact, Between Curtains of Martín Gaite shows an ideology that advocates for women who were not valued as deserved at the time. Against Franco's totalitarianism the author indirectly revealed readers an attempt to improve the situation of women, criticizing the tradition. On the other hand, Delibes sought a new way of presenting the novel in Five Hours with Mario to avoid Franco regime's censorship. The author hid behind a character that represents Franco's politics to criticize the society of that time. The both authors as representatives of contemporary Spanish literature demonstrate that the oppression does not restrict the authors' ability to create unexpected works.

Cancer of the oral cavity and pharynx represents the 7th most diagnosed malignancy in Spain. Mucoepidermoid carcinomas are the most frequent malignancies of the minor salivary glands of oral cavities. The purpose of this report is to describe the very rare case of an alveolar ridge high-grade mucoepidermoid carcinoma presenting as an inside socket radiolucent lesion, simulating an apical cyst. The patient was diagnosed in our unit for oral and maxillofacial surgery and treated with surgery and adjuvant radiotherapy. The patient continues to be free of recurrent/persistent, local/regional disease after two years of follow up. Non-healed tooth related lesions present for more than one year are strongly recommended to be biopsied and evaluated histopathologically.

Human exposure to pollutants has been on the rise. Thus, researchers have been focused on understanding the effect of these compounds on human health, especially on the genetic information by using various tests, among them the somatic mutation and recombination tests (SMARTs). It is a sensitive and accurate method applicable to genotoxicity analysis. Here, a comprehensive bibliometric analysis of SMART assays in genotoxicity studies was performed to assess publication trends of this field. Data were extracted from the Web of Science database and analyzed by the bibliometric tools HistCite, Biblioshiny (RStudio), VOSViewer, and CiteSpace. Results have shown an increase in the last 10 years in terms of publication. A total of 392 records were published in 96 sources mainly from Brazil, Spain, and Turkey. Research collaboration networks between countries and authors were performed. Based on document co-citation, five large research clusters were identified and analyzed. The youngest research frontier emphasized on nanoparticles. With this study, how research trends evolve over years was demonstrated. Thus, international collaboration could be enhanced, and a promising field could be developed.

This year(2012) marks the 30th anniversary of the Malvinas (Falkland) war. A series of talks between the British and Argentina took place over 30 years until 1982, but failed to reach a conclusion on sovereignty. Argentina claims that sovereignty of the islands was transferred to Argentina from Spain upon independence, a principle known as uti possidetis juris. But UK claims that the principle of uti possidetis juris is not accepted as a general principal of international law, and UN General Assembly resolutions calling for negotiations are flawed because they make no reference to the islanders' right to choose their own future. In this situation, a huge amount of petroleum and natural gas has discovered near the Malvinas islands. To explore such situation, this article looks into history and present condition on dispute of Malvinas sovereignty, and also analyses de-colonialism and resource nationalism related to dispute of Malvinas sovereignty.

Private participation on public infrastructures projects is being promoted by governments of several developing countries, among them Colombia. As a result, several advantages such as service delivery efficiency, technology application and faster execution of the projects have been recognized. Hence, the Colombian Government is looking for schemes that allow the private investment in projects like hospitals, schools, prisons and public edification. In this paper, experiences in PPP from other countries were analyzed and adjusted to the Colombian environment. As a result, a model adapted to Colombia is presented, based on a well-developed case from Spain. The awarding process is defined by economic criteria, previous compliance of minimum technical exigencies. Once the infrastructure is operating, contractual periodical payments will be done, based on the performance of the facility.

This research is situated at the intersection between industry 4.0, circular economy and tourism, in an attempt to observe the fourth industrial revolution at the service of the application of circular economy principles in the tourism industry. This approach has gained importance due to the COVID-19 pandemic, which has accelerated fundamental dynamics of change linked to business digitization and environmental sustainability. Within the theoretical framework delimited by the aforementioned intersection, the 'goCircular Radar' project, launched by 'TheCircularLab', from Ecoembes (Spain), has been taken as an empirical reference. Among the 165 startups in the circular economy sector, special attention has been paid to those that are oriented, or have a potential application, to tourism. The activities they carry out are described, with particular attention to the technologies they use and their contribution to circularity.

Highly radioactive waste is solidified to restrict leaching, retain its shape, and maintain its structural stability to prevent it from affecting humans and the environment as much as possible. This operation should be performed consistently regardless of whether the waste is homogeneous or heterogeneous. However, currently, there are no specific performance requirements for heterogeneous waste in Korea. This study reviewed domestic research results and the status of overseas applications, and proposed immobilization requirements for heterogeneous waste to be applied in Korea. IAEA safety standards, domestic laws, and waste acceptance criteria were reviewed. The status of heterogeneous waste immobilization in countries such as the United States, France, and Spain was reviewed. Most countries treat heterogeneous waste by encasing it in concrete, and impose immobilization requirements on this concrete. Based on these data, safety standards for the thickness, compressive strength, and diffusion limit of this concrete material were proposed as immobilization requirements for heterogeneous waste disposal in Korea. Quantitative values for the above requirements need to be derived through quantitative assessments based on the characteristics of domestic heterogeneous waste and disposal facilities.

남극해에는 산업적으로 유용한 신규 효소촉매를 생산하는 미생물들이 들어 있다. 우리는 로스해(Ross Sea)로부터 분리한 여러 저온성 박테리아를 조사하였으며, 그 중에서 지방분해 능력이 뛰어난 Croceibacter atlanticus (No. 40-F12)를 찾았다. Shotgun 클로닝 방법으로 리파아제 유전자(lipCA)를 찾았으며 Escherichia coli 균에서 LipCA 효소를 발현하였다. Spain Arreo metagenome alpha/beta hydrolase를 기준으로 LipCA 상동구조모델을 만들어서 분석한 결과, ${\alpha}/{\beta}$ hydrolase fold, Gly-X-Ser-X-Gly motif, 그리고 lid 구조를 갖고 있기 때문에 전형적인 리파아제 효소임이 밝혀졌다. Ammonium sulfate 침전법과 겔여과 크로마토그래피를 통해서 세포추출액으로부터 LipCA 효소를 순수하게 분리한 후, 최적 온도, pH, 안정성, 기질특이성, 유기용매 안정성 등의 효소특성을 규명하였다. LipCA를 cross-linked enzyme aggregate (CLEA) 방법으로 고정화하고 효소특성을 조사, 비교하였다. 고정화를 통해 온도, pH, 유기용매에 대한 안정성이 증가하였고 기질특이성의 변화는 관찰되지 않았다. $LipCA^{CLEA}$는 원심분리 방법으로 쉽게 회수되었고 4번의 재사용 후에 40% 이상의 활성이 잔재하였다. 이 논문은 C. atlanticus 리파아제의 발현, 특성규명, Cross-linked Enzyme Aggregated 고정화를 바탕으로 안정성을 높여 산업적 활용 가능성을 제시한 최초의 보고이다.
