This thesis suggested a method to analyze and utilize the learning materials of the『Korean history』textbook of high school used in the school field since Mar. 2011. When the『Korean history』textbook is carefully analyzed, it will be helpful and referred to created a textbook according to a new curriculum in the future and the effects of efficient textbook utilization are expected. In Chapter I, the importance of a teaching material in history class, in particular, the importance of a textbook was examined. In Chapter II, the 2009 revised curriculum and the characteristics of the『Korean history』textbook were analyzed. The『Korean history』textbook revised in 2009 reduced and adjusted the recent and modern parts from the『Korean history』textbook revised in 2007 and the two units corresponding to the premodern were added. In addition, the revolution from classifier to general history is the biggest characteristics. The『Korean history』textbook has a positive aspect to collect various data which can improve historical inquiry power, imagination and judgment. Various data which raise practical utilization as well as consider student’s interest have been reinforced. Chronological tables and maps are located in in-depth learning and introduction parts for higher utilization and the sizes and composition of suggested data became diverse and it is analyzed that it developed in creativity of design compared to the existing textbooks. In Chapter III, the learning materials suggested in the textbook large size unit III of the『Korean history』textbook were divided to literal materials and non-text materials for analysis and examination. The ratio occupied by non-text materials among the whole learning materials suggested in textbook Unit VIII of the『Korean history』textbook was 69% and in particular, the ratio occupied by pictures and drawings was high. When it comes to the characteristics of the modern history, because pictures still exist a lot, it is analyzed that pictures and drawings are suggested abundantly. Samhwa and Cheonjae include much more pictures compared to other textbooks. However, when pictures and drawings are compared, drawings were smaller relatively but original materials such as ‘Massacre in Korea’ suggested by Mirae and Cheonjae could be found. In general, maps are a few and mostly related to the Korea War. Chronological tables of Samhwa and Cheonjae placed horizontal chronological tables in each middle size unit or repeatedly suggested chronological tables of overlapped times to raise utilization and Samhwa and Jihak suggested relatively many tables and graphs. Reading materials are the biggest parts among literal materials regardless of publishers and Mirae and Samhwa arranged relatively less wing writings. But, the inquiry data in which student’s activities and postscripts are suggested are provided with various types in all of 6 type textbooks so that it is expected to help improve historical thinking power. Chapter IV suggested character inquiry learning and discussion learning and historical newspaper production learning as a utilization method of textbook learning materials which can enable positive activities of students. Even though a textbooks is not perfect, through recomposition of contents and materials, teachers can find various methods for improvement of student’s historical inquiry power and fill up the insufficient parts of the textbook. Agony and efforts of teachers can fill up the insufficient parts of a textbook and bring quality improvement of history class. For this, teachers should put their endless efforts for much better history class such as recomposition of teaching and learning methods and materials and contents.

In the cloud computing field, cloud migration is recognized as important technology. Currently, cloud computing infrastructure is attempting to build an SDI(Software-Defined Infrastructure) environment based on the paradigm called AIaaS(AI-as-a-Service). Furthermore, when applying migration, a pattern-based or resource-based method is emerging. However, research on identifying migration features that are the basis of such methods and using them for learning is insufficient. Therefore, in this paper, we identified migration features for cloud computing. In addition, the architecture and process for performing migration by adapting the identified features are presented. A case study of learning and applying some of the migration features from a previously published data set was conducted. The proposed model will be applicable as a base feature model for learning when performing AI-based migration in the cloud computing field. 클라우드 컴퓨팅 분야에서 마이그레이션 기술의 중요성이 부각되고 있다. 현재 클라우드 컴퓨팅 인프라는 AIaaS(AI as a Service)라는 패러다임 하에 클라우드 컴퓨팅의 SDI(Software-Defined Infrastructure)환경을 구축하려는 시도가 진행되고 있다. 현재 마이그레이션을 적용 시 패턴 기반, 리소스 기반으로 수행하고자 하는 기법이 등장하고 있다. 하지만, 이와 같은 기법에 근간이 되는 마이그레이션 피처를 식별하고 이를 학습에 활용하는 연구는 미비한 실정이다. 따라서, 본 논문에서는 클라우드 컴퓨팅 마이그레이션 학습 피처들을 식별하였다. 또한, 해당 피처를 접목하여 마이그레이션을 수행하는 아키텍처 및 프로세스를 제시하였다. 실제 마이그레이션 피처 중 일부를 기 공개된 데이터 세트를 통해 학습하고 적용하는 사례연구를 수행하였다. 제안한 모델은 클라우드 분야에서 AI 기반의 마이그레이션을 수행 시 학습 적용을 위한 피처 모델로 활용 가능할 것이다.

Local Rate of Short-hard Gamma-ray Bursts and Their Progenitor Lifetimes

정수민,이창환 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.56 No.5

Gamma-ray bursts have been divided into two classes, long-soft gamma-ray bursts (L-GRBs) and short-hard gamma-ray bursts (SHBs) according to the bimodal distribution in the duration time. Due to the harder spectrum and the lack of afterglows of short-hard bursts in optical and radio observations, different progenitors for short-hard bursts and long-soft bursts have been suggested. Based on the X-ray afterglow observation and the cumulative red-shift distribution of short-hard bursts, Nakar et al. (2006) found that the progenitors of short-hard bursts are consistent with old populations, such as mergers of binary neutron stars. Recently, the existence of two subclasses in long-soft bursts has been suggested after considering multiple characteristics of gamma-ray bursts,including fluences and duration times. In this work, we extended the analysis of the cumulative redshift distribution to two possible subclasses in L-GRBs. We found that two possible subclass GRBs show different red-shift distributions, especially for red-shifts z > 1. Our results indicate that the accumulative red-shift distribution can be used as a tool to constrain the progenitor characteristics of possible subclasses in L-GRBs.

Most facilities in chemical plants operate in environments that are outside therange of temperature and pressure that can be encountered on a daily basis, and are vulnerableto aging due to these stresses and environmental conditions. The facilities exposed to theseconditions are not only likely to fail due to cumulative damage, but also lead to accidents ifmaintenance and replacement are not performed.Recommendation guidelines called risk-basedinspection are widely used around the world-wide. However, limits exist for facilities that havealready elapsed for a certain. As a result of the survey on the aging of Ulsan industrial complexin Korea, which carries out proper inspection, many of the facilities have been used for20 years. Also, most of the facilities where the accident occurred have been in operation formore than 20 years. Therefore, this study suggested criteria for classifying devices that haveexceeded a certain period of use as obsolete facilities. In addition, quantitative risk assessmentwas conducted. The safety investment method using the cost-benefit analysis method was proposedin order to calculate the loss cost and reduce the risk by expressing the risks of thecorresponding aged facility as an Economic index. By utilizing the method of cost-benefit analy-sis of old facilities using the quantitative risk assessment presented in this study, it can beexpected to improve the performance and life of old facilities, improve production efficiencyand reliability of the system of facilities, change the recognition of safety management costs,increase employee stability, and reduce loss costs. 대부분의 화학공장 내 설비는 유해물질을 취급하거나, 일상적으로 접할 수 있는 온도 및 압력의 범위를 벗어난환경에서 가동되며 이러한 응력 및 환경조건으로 인하여 노후화에 취약하다. 이러한 조건에 노출된 설비는 지속적인 손상이 누적되어 고장이 발생할 가능성이 높아짐은 물론, 정비 및 교체를 하지 않는다면 사고로 이어진다. 전세계적으로 위험성기반검사(Risk Based Inspection)라는 권고지침이 통용되고 있다. 하지만 RBI는 이미 일정시간 경과한 설비에 대해서는 한계가 존재한다. 적절한 점검을 수행하는 우리나라 울산 산업단지의 노후화 실태 조사 결과, 많은 수의 설비들이 사용기간이 20년을 경과하였다. 또한, 사고가 일어난 설비 대부분이 20년 이상 운영해 왔다. 따라서 본 연구에서는 일정 사용기간이 초과된 장치를 노후설비로 분류하는 기준을 제시하였다. 또한, 이에 대하여정량적 위험성평가를 진행하였다. 이로 인해 도출된 해당 노후설비의 위험성을 Economic index로 표현하여 손실비용을 산정하고 Risk를 감소하기 위하여 비용편익 분석 방법을 활용한 안전투자 방법을 제안하였다. 본 연구에서 제시한 정량적 위험성 평가를 이용한 노후설비의 비용편익 분석 방법을 활용하여 노후 설비의 성능 향상 및 수명 연장, 생산 효율성 및 설비 계통 신뢰도 향상, 안전관리 비용 인식 변화, 그리고 직원의 안정감 증대, 손실비용의 감소를 기대할 수 있다.

The Slewing Mirror Telescope (SMT) is a key telescope of Ultra-Fast Flash Observatory (UFFO) space project to explore the first sub-minute or sub-seconds early photons from the Gamma Ray Bursts (GRBs) afterglows. The first realization of UFFO is the 20kg UFFO-Pathfinder (UFFO-P) to be launched on board the Russian Lomonosov satellite in 2013 by the Soyuz-2 rocket. Once the UFFO Burst Alert & Trigger Telescope (UBAT) detects the GRBs, Slewing mirror (SM) will rotate to bring the GRB into the SMT's field of view instead of slewing the entire spacecraft. SMT can image the UV/Optical counterpart with about 4-arcsec accuracy. However it will provide a important understanding of the GRB mechanism by measuring the sub-minute optical photons from GRBs. SMT can respond to the trigger over $35^{\circ}{\times}35^{\circ}$ wide field of view within 1 sec by using Slewing Mirror Stage (SMS). SMT has 10-cm Ritchey-Chretien telescope and $256{\times}256$ pixilated Intensified Charge-Coupled Device (ICCD) on focal plane. In this paper, we discuss the overall design of UFFO-P SMT instrument and payloads development status.
