The ASCII ENDF format for nuclear data has been used for four decades. It is practical for human inspection and portability, but it is not very effective for manipulating and displaying the data or for using them in Monte-Carlo applications. In this paper we present a prototype of a nuclear data manipulation package (TNudy) based on the ROOT system (http://root.cern.ch). The ROOT object-oriented C++ framework is the de-facto standard in high energy and nuclear physics since ten years. Starting from the ENDF format, the data is stored in machine-portable binary format. Root files also offer a powerful direct access capability to their different sections and compressibility upon writing, minimising the disk occupancy. ROOT offers a complete library of visualisation and mathematical routines and the Virtual Monte-Carlo system, which allows running different transport Monte-Carlo (Geant 4, Geant 3) with common scoring and geometry modellers, which comes as part of ROOT. ROOT contains isotope decay data and the possibility to describe the evolution of isotopic vectors via Bateman equations. The addition of the ENDF information to Root will allow the development of a transport code for low energy neutrons and other combination of projectile target, either stand-alone as part of the Root system or in combination with some of the other Monte-Carlo systems within the framework of the Virtual Monte-Carlo.

본 연구에서는 인도인 한국어 학습자(IKL)와 한국인 모어화자(KNS) 사이에 첫 인사할 때 어떤 시사점이 나타나는지에 대한 파악하고자 하였다. 첫 인사를 할 때, 모국어(힌디어 모어 화자,INS) 영향이 얼마나 미치는지에 대한 확인하기 위해서 인도인 힌디어 모어 화자를 선택했다. 모든 집단에 20명이었다. 모든 참여자가 네루대학교에서 공부하는 대학원생이었고 나이는 20대-30대 있었다. 인도인 한국어 학습자를 토픽 (3급-5급) 기준으로 선택 했다. 3급-5급 학습자를 선택한 이유는 초급 학습자가 첫 인사 화행에 대한 지식이 부족하기 때문이다. 선행 연구에서 몇 가지 상황을 선택해서 설문지(쓰는 형식으로) 만들고 세 집 단의 대상으로 담화완성 테스트(DCT)를 통해서 자료를 수집했다. 그리고 썰 Searle( 1976)틀로 바탕으로 얻은 자료를 분석했다. 분석한 결과에 따라서 두 집단(KNS하고 IKL) 사이에 비슷한 점과 비슷하지 않는 점을 제시했다. This research was done in three groups KNS(Korean Native Speakers), IKL(Indian Korean Learners) and INS(Indian Native Speakers) in order to understand the similarities and differences between KNS and IKl about first greeting speech act. INS participants were included in order to understand the mother language influence to IKL while learning the foreign language. In each of the three groups there were 20 participants who were studying in Jawaharlal Nehru University(JNU). the IKL participants were selected based on topic level 3-5. Most of these participants were undergraduate or graduate students and theirs age were between 20s-30s. Present researched was conducted in the form of DCT (Discourse Completion Tests)under the different circumstances in the questionnaire based on previous researched which was in the written form. After the materials were collected by DCT, results were analyzed based on the Searle(1976) model analysis. And the similarities and differences between KNS and IKl about first greeting speech act were presented.

Healing process in scarring inevitably produces a considerable amount of non-organized dense collagen-rich matrix called scar thus impairing the native structure of skin. Connective tissue growth factor (CTGF) overexpression within healing tissues is known to play an imperative role in collagen production stimulated by transforming growth factor-beta in cutaneous wound healing. Undoubtedly, the knockdown of CTGF expression through siRNA-mediated gene silencing could simply impede the scarring process. However, the less stability and low transfection of siRNAs themselves urge a safe carrier to protect and transfect them into cells at a high rate avoiding toxicities. Here, we developed a degradable poly(sorbitol-co- PEI) (PSPEI), prepared by polymerization of sorbitol diacrylate with low molecular weight polyethylenimine, which has high transfection efficiency but low cytotoxicity, and utilized it in siCTGF delivery to silence the expression of CTGF in an animal model of cutaneous wound healing. Unlike contracted scar in normal healing, there was no or less contraction in the healed skin of mice treated with siCTGF using PSPEI. Histologically, the healed tissues also had distinct papillary structures and dense irregular connective tissues that were lacking in the control scar tissues. This study exemplifies a successful treatment of cutaneous wound healing using a polymer system coupled with RNA interference. Hence, the approach holds a great promise for developing new treatments with novel targets in regenerative medicines.
