For many mission-critical related wireless sensor network applications such as military and homeland security, user's access restriction is necessary to be enforced by access control mechanisms for different access rights. Public key-based access control schemes are more attractive than symmetric-key based approaches due to high scalability, low memory requirement, easy key-addition/revocation for a new node, and no key predistribution requirement. Although Wang et al. recently introduced a promising access control scheme based on elliptic curve cryptography (ECC), it is still burdensome for sensors and has several security limitations (it does not provide mutual authentication and is strictly vulnerable to denial-of-service (DoS) attacks). This paper presents an energy-efficient access control scheme based on ECC to overcome these problems and more importantly to provide dominant energy-efficiency. Through analysis and simulation based evaluations, we show that the proposed scheme overcomes the security problems and has far better energy-efficiency compared to current scheme proposed byWang et al.

The purpose of this paper is to investigate into the meaning of the New Brutalism sensed in the late church buildings of the Swedish architect Sigurd Lewerentz (1885-1975). St Mark's (1956-64) and St Peter's (1962-66) churches, his grand finale designs, have a unique architectural vocabulary of rough brickwork. The brick treatment is the basis on which Reyner Banham (1966) discussed him concerning the New Brutalism, and the point that this research focuses on. This paper explores the brutalist character of the buildings from two aspects - interpretational level of individual buildings and historical level of a broader view. First, the character of two churches could be interpreted with the phrase of 'play between brutality and sacredness'. The rough surface of brick and mortar in the buildings symbolises brutality and the vault of their chapels' ceiling sacredness. And the two characteristics meet and play on the rough vault surface. Second, in the historical point of view, this paper argues that the buildings made a giant leap for Swedish modern architecture, which had been at a deadlock owing to the compromising attitude of the New Empiricism since 1940s. And the Swedish New Empiricism (or the New Humanism), spread to Britain as "Welfare State architecture" after World War II, brought about reaction of the young British architects such as the Smithsons and became the background that made the new brutalist mood. However, considering that the term of the New Brutalism was first used in Sweden by Hans Asplund, Lewerentz's brutalist late churches - which seemingly had nothing to do with the British nor the Corbusian lineage - are also meaningful in that they confirmed the tendency in its homeland. In conclusion, this paper argues that St Mark's and St Peter's churches with the brutalist characteristics should be regarded as crucial buildings not only in Lewerentz's personal career but also in Swedish and international architectural history.

To solve the serious problem of insufficient manpower in medium and small scaled companies, our country allows introduction of foreign manpower for 5 business types such as manufacture industry, service industry, etc. and there are 226,825 people who entered by employment license system(E-9) in Sep. 2013. However, according to the results of investigation "actual status and difficulties of foreign manpower's employment of medium and small scaled manufacturing companies" of KFTA in 2013, 36.4% of respondents responded that current scale of introducing foreign manpower is insufficient to solve difficulties of insufficient manpower in industrial world and 37.7% of them responded that the quarter of new employment is insufficient. So, they hope that current quarter system of foreign manpower can be abolished. Meanwhile, introduction scale of foreign manpower was decided by 53,000 people so as to solve enterprise difficulties in manpower and vitalize economics this year, but illegal aliens are 39,623, more than 17.5%, in Sep. 2013 after employment expiration. Therefore, it becomes serious social problem. Government displays various support businesses so that foreign workers after employment expiration can return to their homeland legally. This thesis intends to find measures to maintain royalty for our country and support their smooth resettlement through the analysis on homecoming support business of foreign workers.

The saga of Megascolides orthostichon (Schmarda, 1861)-the first native worm described from Australasia-continues as its type-locality is unequivocally returned from Hobart, Tasmania to Mt Wellington, Auckland where a brief survey failed to unearth it. Since it has not been seen for 150 yrs, it may qualify under NZTCS or IUCN classification as 'Nationally Critical' if not 'Extinct'. New reports are for exotic Megascolecidae Anisochaeta kiwi sp. nov. and A. kiwi mihi sub-sp. nov. plus addition to the NZ faunal list of Australian Anisochaeta macleayi (Fletcher, 1889) that, due to its wide distribution in Australia and now New Zealand, may be a candidate model-species suitably resilient for eco-toxicological culture and monitoring. For holarctic Lumbricidae, new records are of Dendrobaena attemsi (Michaelsen, 1903) and the Murchieona muldali (Omodeo, 1956) morph or subspecies of M. minuscula (Rosa, 1906), neither lumbricid previously uncovered in Asia/Australasia. Also found for the first time outside its East Asian homeland is Eisenia japonica (Michaelsen, 1892) (which is compared to Japanese E. japonica hiramoto sub-sp. nov. and to E. anzac Blakemore, 2011). Records of these exotics plus recent new native species described by the author-including two, Rhododrilus mangamingi and Deinodrilus orcus spp. novae, herein-raise the numbers of megadriles known from New Zealand to 228 (sub-)species in five families. Preliminary mtDNA COI sequence barcodes are presented. Genus Tokea Benham, 1904 is revived on its lack of dorsal pores, losing or gaining some species with Megascolides M'Coy, 1878. An updated checklist of all 228 New Zealand taxa is appended.

영화감독 양영희의 두 편의 다큐멘터리 <디어 평양>(2005), <굿바이, 평양>(2009)과 극영화 <가족의 나라>(2013)는 재일코리안 디아스포라로서 감독의 자전적 경험을 바탕으로 제작된 영화로 남북한과 일본이라는 국민국가의 틈바구니에 선 재일코리안 디아스포라 문제를 제기하고 있다. 세 편의 영화는 제주, 오사카, 평양을 횡단하며 구축된 가족의 서사를 질문하는 것을 통해 국민국가가 부과한 경계를 의심하고 '가족의 나라'라는 새로운 탈주의 공간을 모색한다. 이 글은 양영희의 영화가 분단으로 한반도에 발생한 두 개의 국민국가가 강력하게 추구하는 통합과 일체감, 조국에 대한 획일적인 교육에 긴장을 일으키고 그것을 이질화시키면서 자신의 정체성을 재조정해가는 과정을 추적하였다. 결국 이들 영화는 국민국가의 경계를 넘나드는 혼종적 정체성에서 재일코리안 디아스포라의 미래 정체성을 예견하고 있는데 이는 동북아의 평화와 공존, 남북한의 적대성을 해체하는 작업에서 요구되는 타자 수용성, 개방성, 연대성의 가능성이 재일 코리안 디아스포라에게 있음을 보여주는 것이라 할 수 있다.

The purpose of this study is to compare and analyze the application of raditional elements in Lie Sang bong and Vivienne Tam's Fashion Design. The methods of research, the references to the precedents of prior research, fashion related journals, articles, and websites of designers were examined to analyze how each designer reinterpreted the respective homeland's traditions. The designs of Lie Sang bong and Vivienne Tam studied were from the 2002-03 F/W to the 2012 S/S collections. The results are as follow. First, both designers use traditional marks when reinterpreting the traditional clothes of Korea and China. In the case of Lie Sang bong, traditional Korean marks were linked to the western structure. For Vivienne Tam, designs which revived realistic marks identically were displayed. Second, in terms of the modern reinterpretation of the traditional clothes shapes, there were a number of cases in which the silhouettes of their respective country's traditional clothes were mainly brought into their arts. Lie Sang bong was influenced by the 'line' of traditional Korean design. In addition, the atmosphere of the traditional clothes helped to reanalyze the traditional clothes' figure. In Vivienne Tam's designs, unique Chinese images were produced by, keeping the original form of the Chinese dress. Third, in the use of the traditional ornament techniques, Lie Sang bong partially introduced and applied traditional ornament techniques while Vivienne Tam largely decorated the traditional. Chinese ornaments while directly utilizing the structuring designs.

Accurate localization of radioactive materials is crucial in homeland security and radiological emergencies. Coded-aperture gamma camera is an interesting solution for such applications and can be developed into portable real-time imaging devices. However, traditional reconstruction methods cannot effectively deal with signal-independent noise, thereby hindering low-noise real-time imaging. In this study, a novel reconstruction method with excellent noise-suppression capability based on a multi-layer perceptron (MLP) is proposed. A coded-aperture gamma camera based on pixel detector and coded-aperture mask was constructed, and the process of radioactive source imaging was simulated. Results showed that the MLP method performs better in noise suppression than the traditional correlation analysis method. When the Co-57 source with an activity of 1 MBq was at 289 different positions within the field of view which correspond to 289 different pixels in the reconstructed image, the average contrast-to-noise ratio (CNR) obtained by the MLP method was 21.82, whereas that obtained by the correlation analysis method was 5.85. The variance in CNR of the MLP method is larger than that of correlation analysis, which means the MLP method has some instability in certain conditions.

Since 1989 about one million Jews from Former Soviet Union have immigrated to Israel. Now Russian speaking Jews are the second largest ethnic groups after the Israeli Jews who were born in Israel. Although FSU Jews have returned to their ethnic homeland, they continue to live as 'foreigners' due to a cultural distance between sending and receiving society, such as, lack of knowledge about Jewish tradition and religious practice and low level of Hebrew proficiency. Because of this reason FSU immigrants tend to continue remain strong ties with Russian language and culture. There are several reasons for such a relatively slow process of language shift of FSU Jewish immigrants, the language shift to Hebrew. Firstly, majority of FSU immigrants moved to Israel since the 1990s are older than 45. Secondly, their first residences in Israel are mostly located in small and mid-sized cities, where the proportion of Russian speaking immigrants is more than 30%. And finally they consider Russian culture is 'superior' to Israel's Levantine culture. For many Jewish diasporic communities, Judaism was a dominant factor for self-consciousness, but because of Soviet regime, aimed to break all the religious institution including Jewish, Soviet Jewry was uprooted from their religious traditions. Besides about 30% of FSU immigrants are not defined as Jews by the Jewish religious law(Halakhah). And many of them are reluctant to convert to Judaism. FSU Jewish immigrant agree that Israel must be a Jewish state, but for them 'Jewish' does not include religious elements. FSU immigrants consider that religious affiliation of citizens of Israel should not affect their civic rights.
