  • Structure-physical properties relationships for Aurivillius ceramics are discussed, with empha-sis in symmetry considerations. Single-crystal materials and polycrystal ceramics are analysed. Electric and magnetic coupling properties are considered. Colour Symmetry Groups and Texture Analysis tool are emploed. Symmetry conditions for polarisation vectors and inverse pole figures related to Aurivillius phases are given. The influence of crystallographic texture of the physical properties of polycrystalline Aurivillius ceramics is evaluated.

  • The key step in a strategy for the synthesis of (+)-lactacystin involving photocyclization reaction of a cyclopenta-fused pyridinium salt has been probed by using a model substrate. Observations made in this effort led to the discovery of a highly unusual cascade process that leads to stereoselective formation of an interesting tricyclic carbamate. The results of this study are presented and discussed in the context of a (+)-lactacystin synthetic approach.

  • Public Diplomacy (PD) is the third pillar of South Korean foreign policy. According to the Ministry of Foreign Affairs, PD aims to attract foreign audiences by means of art, knowledge transmission, media, language and foreign aid. When it comes to the Korean language, its global profile has seen an especially marked increase in recent years (Kim, 2009). Thus, this paper's objective is to explain the relevance of the Korean language in the generation of South Korea's soft power. I draw from $C{\acute{e}}sar$ Villanueva's reflections in order to problematize how language promotion can be translated into soft power at five different levels: the empathetic, the sympathetic, the geopolitical, the diplomatic and the utilitarian. I observe that in the case of the Korean language in Mexico City, soft power has the potential to be generated on three levels: it helps to increase knowledge of Korean culture (empathetic); it exercises symbolic persuasion (geopolitical), since the products of cultural industries are mostly in Korean; and it is used as a tool for economic transactions in Mexico City (utilitarian).

  • 본 논문은 제3차 전력수급기본계획을 토대로 2010년부터 2020년도까지 우리나라 장기전력계통의 공급신뢰도를 MEXICO 모형을 이용해 전망한 결과를 분석한 것이다. 지금까지 전력계통 신뢰도에 대한 연구들은 주로 발전계통을 대상으로 한 결정론적 신뢰도 산정을 다루었던 반면 MEXICO 모형을 이용한 분석은 발전설비와 송전선로의 불확실성까지 고려한 복합 전력계통을 대상으로 실질적인 신뢰도 평가를 수행하였다는 점에서 의미가 있다. 주요 검토 내용으로는 2010년, 2012년, 2014년, 2020년도에 대한 공급지장에너지 및 공급지장비용분석 등을 다루고 있으며 이번 논문에서 사용된 신뢰도 평가방법은 향후 전력설비(발전 및 송전 설비계획의 복합 부분)의 확충계획 수립에 환웅이 가능할 것이다.

  • Lipomas are benign mesenchymal tumors that develop in areas of abundant adipose tissue. Due to the fatty composition of the breast, difficulties in diagnosis, treatment, and reconstruction are often encountered. We report a case of a 55-year-old female with a giant tumor of the right breast that comprised most of its mass, causing breast asymmetry. A thorough preoperative evaluation, followed by an uneventful difficult surgical resection and reconstruction, resulted in diagnosis of a benign lipoma. The case prompted this report because of its challenging size, location, diagnosis, and reconstructive solution.

  • Tall buildings are subjected to wind loading that can cause excessive wind-induced vibration. This vibration can affect the activities of the inhabitants of a building and in some cases fear for safety. Many codes and standards propose the use of curves of perception of acceleration that can be used to verify the serviceability limit state; however, these curves of perception do not take into account the uncertainty in wind-climate, structural properties, perception of motion and maximum response. The main objective of this study is to develop an empirical expression that includes these uncertainties in order to be incorporated into a simple procedure to evaluate the wind-induced acceleration in tall buildings. The use of the proposed procedure is described with a numerical example of a tall building located in Mexico.

  • In the past years, the influx of Korean tourists to international destinations has seen a significant rise, especially in non-Asian countries. However, Mexico is still far from a popular destination to the average Korean tourist. Using Keller's brand equity model, this paper researches Koreans' opinions and general brand image of Mexico in an attempt to identify both the positive and negative perceptions they have of this country. Keller's brand model analyses four different levels of engagement between the customers and the brand. We want to know the degree to which Koreans have been engaged in Mexico as a brand nation and as a tourist destination. Research findings through this study will reveal the needs and insights that offer opportunities relevant for the planning, creation, design and development of new approaches for Mexico's nation brand promotion.

  • Objectives: Airway management in patients with panfacial trauma is complicated. In addition to involving facial lesions, such trauma compromises the airway, and the use of intermaxillary fixation makes it difficult to secure ventilation by usual approaches (nasotracheal or endotracheal intubation). Submental airway derivation is an alternative to tracheostomy and nasotracheal intubation, allowing a permeable airway with minimal complications in complex patients. Materials and Methods: This is a descriptive, retrospective study based on a review of medical records of all patients with facial trauma from January 2003 to May 2015. In total, 31 patients with complex factures requiring submental airway derivation were included. No complications such as bleeding, infection, vascular, glandular, or nervous lesions were presented in any of the patients. Results: The use of submental airway derivation is a simple, safe, and easy method to ensure airway management. Moreover, it allows an easier reconstruction. Conclusion: Based on these results, we concluded that, if the relevant steps are followed, the use of submental intubation in the treatment of patients with complex facial trauma is a safe and effective option.

  • Maquiladora industries have grown due to the decrease in labor costs caused by Mexico's economic crisis and the increase in possibility of Mexico's advance into North American markets caused by the NAFTA that come into effect since the 1980s and 1990s. Early Marquiladora industries have started to be located in the Northern borders of Mexico using young-female labor forces centered on the textile and electronic part industries. However, after the 1980s, the port soared, and the regional range of Maquiladora industries has also enlarged to 25 states. The most important regions of Maquiladora industries in Mexico are Chihuahua and Baja California and their cities are Ciudad Juares and Tijuana. Maquiladora industries had grown in terms of the cost of product and the employment until the end of the 1990s. However, Maquiladora industries have decreased in the cost of product and the employment since the 2000s. The regional range of Maquiladora industries has enlarged into the entire of Mexico, but most of Maquilador industries is still located in Northern border regions centered on six states. The textile industry is a representative one of Maquiladora industries and the early Maquilador industries have been focused on the textile industry. Thus, the textile industry in Maquiladora shows the same pattern as any other industries in Mexico. However, machinery and electronic part industries have been concentrated on the Northern border states and existing manufacturing zones. In terms of the change in employment by industry, machinery and electronic part industries occupied most high employment proportion and the textile industry sector was the next. The distinguished point is that service industries are growing.
