Smart metering systems have become widespread around the world. RF mesh communication systems have contributed to the creation of smarter and more reliable power systems. This paper presents an algorithm for positioning GPRS concentrators to attain delay constraints for a ZigBee-based mesh network. The proposed algorithm determines the number and placement of concentrators using integer linear programming and a queueing model for the given mesh network. The solutions given by the proposed algorithm are validated by verifying the communication network performance through simulations.

Cashew apple juice and cajuina (processed juice) are drinks widely consumed in northeast Brazil. In vitro studies have shown that both juices have antimutagenic activity as well as antioxidant effects. These juices contain vitamins, carotenoids, and phenolic compounds. This in vivo study assessed the antigenotoxic and anticlastogenic effects of both drinks against genotoxicity and mutagenicity induced by cyclophosphamide. The comet, micronucleus, and chromosome aberrations tests were used. Male Swiss mice were divided into 6 groups (5 animals per group) and received the following by gavage, 0.15 mL/10 g body weight: group 1, water; group 2, cashew apple juice; group 3, cajuina juice; group 4, cashew apple juice and cyclophosphamide (50 mg/kg); group 5, cajuina juice and cyclophosphamide; group 6: cyclophosphamide. Both drinks significantly reduced DNA damage of peripheral blood cells (P<.001), with modulation percentages of 60.82% (cashew apple juice) and 82.19% (cajuina) when compared with the cyclophosphamide group. Cashew apple juice and cajuina modulated cyclophosphamide-induced micronucleus frequency, with up to 80.0% inhibition. Cashew apple juice and cajuina decreased the average number of cells with chromosome aberrations in bone marrow of mice by 53% and 65%, respectively. These findings demonstrate the high antigenotoxic and anticlastogenic potential of cashew apple juice and cajuina in vivo, which can be related to the antioxidant compounds found in both drinks.

Maxillofacial images must be examined to find pathologies not identified during clinical examination. Unicystic ameloblastoma (UA) extending to the mandibular body and ramus was neglected on initial panoramic radiographic examination. After orthodontic therapy, a huge lesion was observed clinically and through imaging exams. After the conservative surgery, no recurrence was observed during five years of follow-up. This case emphasized the need for careful evaluation of patient images focusing on the oral diagnosis before any dental treatment planning, including orthodontic therapy.

Tumor response to antineoplastic drugs is not always predictable. This is also true for bladder carcinoma, a highly recurrent neoplasia. Currently, the combination of cisplatin and gemcitabine is well accepted as a standard protocol for treating bladder carcinoma. However, in some cases, this treatment protocol causes harmful side effects. Therefore, we investigated the roles of the genes TP53, RASSF1A (a tumor suppressor gene) and hMLH1 (a gene involved in the mismatch repair pathway) in cell susceptibility to cisplatin/gemcitabine treatment. Two bladder transitional carcinoma cell (TCC) lines, RT4 (wild-type TP53) and 5637 (mutated TP53), were used in this study. First, we evaluated whether the genotoxic potential of cisplatin/gemcitabine was dependent on TP53 status. Then, we evaluated whether the two antineoplastic drugs modulated RASSF1A and hMLH1 expression in the two cell lines. Increased DNA damage was observed in both cell lines after treatment with cisplatin or gemcitabine and with the two drugs simultaneously, as depicted by the comet assay. A lack of RASSF1A expression and hypermethylation of its promoter were observed before and after treatment in both cell lines. On the other hand, hMLH1 downregulation, unrelated to methylation status, was observed in RT4 cells after treatment with cisplatin or with cisplatin and gemcitabine simultaneously (wild-type TP53); in 5637 cells, hMLH1 was upregulated only after treatment with gemcitabine. In conclusion, the three treatment protocols were genotoxic, independent of TP53 status. However, cisplatin was the most effective, causing the highest level of DNA damage in both wild-type and mutated TP53 cells. Gemcitabine was the least genotoxic agent in both cell lines. Furthermore, no relationship was observed between the amount of DNA damage and the level of hMLH1 and RASSF1A expression. Therefore, other alternative pathways might be involved in cisplatin and gemcitabine genotoxicity in these two bladder cancer cell lines.
SPECIAL RELATIONS AND ALLIANCE POLITICS IN PHILIPPINE-U.S. SECURITY RELATIONS, 1990-2002
De Castro, Renato Cruz 경남대학교 극동문제연구소 2003 ASIAN PERSPECTIVE Vol.27 No.1
This article argues that the special relations between the Philippines and the United States undermined their security ties in the early 1990s. It examines the impact of three events on Philippine-U.S. security relations: the end of the cold war, negotiations for a new bases treaty, and cooling off of the special relations between the two allies. The article also analyzes the developments that led to the revival and revitalization of the Philippine-U.S. alliance in the late 1990s and early years of the new millennium. The contention is that security ties based on historical or cultural affinity or special relations are detrimental to alliances because the intimacy or relations creates gross misperception and unwarranted expectations. Therefore, alliances must be viewed as mere power relations that will ensure the survival of states and enhancement of their values in an anarchic international system.
China-United States Trade War : China’s action and the Impact to Taiwan

국제무역은 세계를 하나로 묶고 상호의존적인 관계를 형성시킨다. 미국과 중국은 세계의 가장 큰 경제로 이 둘의 긍정적인 관계는 세게 경제 안정과 발전의 핵심적인 요소로 작용한다. 하지만 최근의 미중 무역분쟁은 양국 관계의 긴장을 유발시키고 있다. 이 논문은 미중 무 역분쟁의 배경, 미국의 선제 행동과 중국의 대응 그리고 이 과정이 대만에 미치는 영향을 분석하고 있다. 이를 통해 미중무역분쟁의 과 정을 요액하고 함의를 도출하고자 한다. International trade helps to connect different parts of the world, establishing interdependent relations. China and the United States are the world’s largest economies and positive relations between these two countries is the key to global stability, and development (CCG, 2018). However, the recent trade war is causing tensions between Sino-US economic ties. This articletackles the background of the U.S.-China trade war, the United States Action and the response of China to the United States’s protectionist measure, and the impact of trade war to Taiwan and its actions towards the issue. This paper will conclude by summarizing the issue and show its implications.
