The site for this plan is located at the foot of Mt. Unseo at Galcheon-ri, Changsu-myon, Youngdeok-gun. On the site stands Jangyutsa Temple, built by priest Naong in 1355 (in the 4th year of King Gongmin during Koryo Kingdom). The purpose of this plan is to widely publicize and commemorate priest Naong by designing a district centering around the temple. The basic directions of design can be summarized as follows 1) A special Buddhists'pilgrimage and sight-seeing district aimed at commemorating priest Naong will be developed to preserve the historic figure of priest Naong. To this end, a facility will be built to collect, preserve and exhibit materials related with the great priest in order to preserve his legacy and enhance the image of the space. 2) Special fractions which are rare in other districts will be introduced to create an image different from the conventional memorial districts or sight-seeing zones. To this end, the district will be divided into the Jangyuksa Temple area proper and a district memorial area, each of which will have its own unique characteristics with different functions. On the other hand, the two different areas will be related with each other and complemented by each other. Such planning techniques as articulation and superimposition will be used for a synergistic effect. 3) The plan will accommodate various programs centering around historical and cultural assets, and at the same time will allow tourists to have various experiences and access to the natural environment as well as to a variety of events. 4) In order to plan such landscapes as shown in the traditional mountain temples, the traditional tectonic forms will be used for the facilities. It is expected that the district surrounding Jangyuksa Temple will become a popular sight-seeing destination, and with new historical and cultural environments will become a valuable resource to widely publicize the culture of Youngdeok-gun.

운동 효과를 극대화하기 위하여 개인의 신체 상태를 측정한 후, 운동 처방을 통하여 적합한 운동 프로그램을 생성해 주는 운동 관리 시스템이 도입되어 활용되고 있다. 하지만, 2주$\sim$3개월 주기로 신체 상태를 파악하여 생성되는 운동 프로그램은 다양하게 변화하는 개개인의 운동 습관이나 운동 주기를 실시간으로 반영하지 못하기 때문에, 운동 기간이 길어질수록 사용자의 현재상태에 적절치 않은 운동을 유도할 수 있다. 본 논문에서는 사용자의 상황을 고려한 운동 프로그램을 제공하기 위한 문맥 인지 운동 모델(Context Aware Exercise Model : CAEM)을 제안하며, 이를 지능형 운동 가이드(Intelligent Fitness Guide : IFG) 시스템으로 구현한다. IFG 시스템은 사용자의 상황에 따라 필요한 측정치를 선택적으로 입력 받고, 운동 종류 및 운동 횟수, 운동 강도의 변경 시 운동 최적화 알고리즘 및 운동 지식베이스를 통해 운동 프로그램을 생성한다. IFG는 사용자 상황에 알맞은 운동 프로그램을 실시간으로 제공함으로써, 사용자 상황에 알맞은 효율적인 운동 관리를 할 수 있다.

클래스 단위의 응용 시스템 구성은 코드 중심의 컴포넌트 추상화로 각 요소의 독립성 유지 및 재사용이 구현상에만 치우쳐 효과가 미흡하다. 따라서 상위의 개발 단계에 대한 객체 지향적 접근을 위해서는 설계 문제의 추상화와 특정 영역의 일반적인 해결에 대한 정보 표현 및 구성요소 상호 간의 관련성을 패턴을 통하여 나타낼 필요가 있다. 또한 기존 시스템의 성능을 변경, 개선하고 변화하는 환경에 적응하기 위해서는 기존 시스템을 실험, 분석함으로써 정확한 이해를 하고 나아가 재사용 자원으로 활용할 수 있는 소프트웨어 역공학이 필요하다. 따라서 본 논문에서는 기존 객체지향 시스템 코드에서 설계 패턴 추출을 위한 역공학 적용에 관한 타당성과 설계 패턴 자동 추출을 위한 알고리즘을 Java를 적용하여 살펴보고 설계 패턴의 자동 추출을 위한 역공학 및 패턴 재사용을 위한 자동화 도구의 아키텍쳐를 설계 구현한다.

본 논문에서는 고속 이동성을 갖는 통신 시스템에서 회귀 신경망을 기반으로 한 페이딩 신호 예측 기법을 제안하고, 이를 이용한 송신 전력 제어를 제안하였다. 회귀 신경망의 연산 결과를 해석적으로 도출하여, 신경망 특유의 회로 복잡도 문제를 해결하고, 연산된 채널 예측치를 이용하여 최대비 결합(maximum ratio combining)방식으로 여러 개의 송신 안테나에 대하여 채널 이득을 산출하고, 이 산출된 값으로 송신 안테나 각각에 대한 송신 전력을 제어하였다. 모의 실험 결과 채널 예측 기반 전력 제어를 하지 않은 것에 비해 쥐어난 성능을 나타냄을 보여준다. 기존의 대부분의 연구들이 페이딩 신호에 강인한 수신기술에 대하여 연구를 하였거나 페이딩 신호에 대한 채널 예측도 저속의 이동성에 국한되어진 것에 비하여, 제안된 채널예측 방법은 개회로 전력제어에 적용하는 경우 송신단에서 페이딩의 영향을 제거하여 신호를 송신하기 때문에 수신 단에서 여타의 요소기술들을 매우 단순하게 설계하거나 시스템의 복잡도를 획기적으로 개선시킬 수 있는 가능성을 제시하였다.

하둡 MR(MapReduce)는 매퍼(Mapper)의 출력을 리듀서(Reducer)의 입력으로 전달하기 위해 파티션 함수(Partition Function)을 사용한다. 파티션 함수는 키에서 해쉬 값을 계산한 후 리듀서 개수로 나머지 연산을 수행하여 대상 리듀서를 결정한다. 기존 파티션 함수는 키의 편중도에 민감하여 잡이 균등하게 배분될 수 없었다. 잡이 균등하게 배분되지 못하면 특정 리듀서들의 처리 수행 시간이 길어져 전체 분산 처리 수행 성능에 영향을 주게 된다. 이에 본 논문은 VPT(Virtual Partition Table)을 제안하고 편중도가 심한 데이터에 VPT을 적용하여 실험을 수행 하였다. 적용된 VPT는 기존 파티션 함수와 대비하여 평균 3초 정도 성능향상이 발생하였으며, 데이터 처리량이 증가할수록 성능 향상 폭이 증가할 것으로 예상된다.

The characteristics of the records management systems of the Japanese colonial government can be summarized as follows. First, the Government General adopted a "decentralized retention" of public records. The Government General did not establish its own archives for central preservation of permanent public records. Colonial agencies established its own records office and the records office managed the records its agency created. Secret records and police records were exception. They were retained by the Secretary Office of the General Affairs Division and Police Division of the Chosun Government General respectively. Second, filing systems and retention periods of the public records followed the hierarchic structure of organization. In the headquarter of the government, records were filed by a "bureau-division-activity-file" classification system and a retention period of a file was given automatically by each unit the file belonged. A closed and cut-off file was retained and arranged according to its creating unit, creating year, and retention period. The filing system was easy to use once the filing system was established well, but to make it work effectively changes in activities and organizations should be on a reflected regular basis. It had an advantageous effect that permanent records could be preserved in a unified way throughout the organization. However, it is very critical to determine the permanent records in a professional way. Selection of the permanent records should be done professionally and in a historical perspective. Otherwise, the records retained as permanent records were not the records having an enduring value. And that was not done by the colonial government. Third, classification and scheduling of records were carried out by a creating division, rather than by the Records Office, mostly from the 1920s. Compilation of the records was also done by the creating agency. It implies that the records management lacked the professionalism. In conclusion, the records management system of the Chosun Government General wes nither modern nor user oriented. It managed the records for solely administrative purpose, i.e. effective colonial rule. The legacy of the colonial records system still exists in the public records system in Korean government. One should criticize the lack of will and efforts to modernize the public records system since the establishment of the Korean government while should reflect the historical origins of the records system in Korea.

Purpose Recently, Internet personal broadcasting has been widely spreaded as a new media type by replacing traditional legacy media such as TV. Considering this phenomenon, this study aims to explore the effect of Aristoteles' persuasion factors on Internet personal broadcasting from a rhetorical view. The reason why users watch the Internet personal broadcasting is that they are persuaded by creator's expertness, empathy, or content usefulness. These factors can be regarded as persuasion factors. Therefore, with Aristoteles' rhetorical persuasion factors composed of ethos, pathos, and logos, this paper tries to investigate how persuasion factors affect user's emotional\ attachment and voluntary donation intention. Design/methodology/approach This paper proposes a model of the relationships among three rhetorical factors, user's emotional attachment, and donation intention. Specifically, ethos is regarded as creator's expertness and trustworthiness, and pathos refers to creator's empathy and social interaction. Last, logos refers to content usefulness and credibility. For testing a hypothetical research model, this study collected 468 surveys and empirically tested hypotheses using a structural equation model. Findings This study investigated how rhetorical factors (ethos, pathos, and logos) and emotional attachment further influence user's donation intention. The findings suggest that rhetorical factors of ethos and pathos enhances emotional attachment, followed by donation intention. Contrary to an expectation, however, logos was not significantly related to emotional attachment. Creators of Internet personal media and MCN providers should focus on the different effects of rhetorical factors and pay attention to the role of emotional attachment to encourage user donation.

본 논문에서 비대칭 멀티 코어 구조의 스마트 모바일 단말에서 실시간성 보장과 에너지 소비량 절감을 고려한 작업 스케쥴링 기법을 제안한다. 최근 VR, AR, 3D 등 고성능 응용프로그램은 실시간과 고수준 작업이 요구된다. 스마트 단말은 배터리에 의존적이므로 높은 에너지 효율을 위해서 big.LITTLE 구조가 적용되었지만, 이를 제대로 활용하지 못함으로써 에너지 절감효과가 반감되는 문제점이 있었다. 본 논문에서는 big.LITTLE 구조의 단말에서 실시간성과 높은 에너지 효율을 높일 수 있는 비대칭 멀티코어 할당 기법을 제안한다. 이 기법은 SVM 모델을 활용해서 실제 작업의 실행시간을 예측하고 이를 통해서 에너지 소모와 실행시간을 최적화한 알고리즘을 제안한다. 상용 스마트폰에서의 비교실험을 통하여 제안기법이 기존 기법과 유사한 실행시간을 보장하면서 에너지 소비량의 절감을 보였다.

In the l950s, under the legacy of traditional agriculture, Ascaris lumbricoides, spread epidemically in the war-bitten society of Korea. Consensus on the parasite control was drafted in the Parasite Disease Prevention Act, which passed a parliamentary agreement in 1966, and established safe disposal of feces and mass chemotherapy as control strategies. Biannual stool examinations and treating infected schoolchildren were basic scheme of the control activity through which revenue could be secured for organized business. In the 27 years following 1969, a maximum of 16 million stool examinations had been done every year. Cellophane thick smear enabled the task. The infection declined remarkably in the 1970s when industrialization and green revolution proceeded. A population study of A. lumbricoides in the late 1970s helped us better understand its epidemiology. The data also settled down the understandable protest of teachers against the repeated stool examinations. In the 9 years following 1987, the target population was gradually reduced when the egg positive rate was below 0.1%. An article in the Korean Law, stipulating obligatory stool examinations, was made optional. Although the long-term Korean effort of Ascaris control was a success, the effect of mass chemotherapy was not as succinct in terms of lowering reinfection. In the period of control, Korean agricultural technology changed, and the economy grew and supplied sanitary facilities by which the vicious cycle was disconnected. Reduction of morbidity was a benefit of mass chemotherapy, which is the only control method feasible in economically difficult countries. The most important hurdle of parasite control in the 1960s was poverty of general population and limited financial resources in Korea but the society formed a consensus on the priority of intestinal helminthiasis control during the ordeal period. The national consensus in the 1960s was the critical milestone for Ascaris control in Korea. Under the social agreement, application of timely technical and research advancements in parasitology achieved the success of ascariasis elimination. The successful experience of ascariasis elimination in Korea can be a benchmark for countries where neglected tropical diseases are endemically recycled.

Minor mergers leave behind long lived, but extremely faint and extended tidal features including tails, streams, loops and plumes. These act as a fossil record for the host galaxy's past interactions, allowing us to infer recent accretion histories and place constraints on the properties and nature of a galaxy's dark matter halo. However, shallow imaging or small homogeneous samples of past surveys have resulted in weak observational constraints on the role of galaxy mergers and interactions in galaxy assembly. The Rubin Observatory, which is optimised to deliver fast, wide field-of-view imaging, will enable deep and unbiased observations over the 18,000 square degrees of the Legacy Survey of Space and Time (LSST), resulting in samples of potentially of millions of objects undergoing tidal interactions. Using realistic mock images produced with state-of-the-art cosmological simulations we perform a comprehensive theoretical investigation of the extended diffuse light around galaxies and galaxy groups down to low stellar mass densities. We consider the nature, frequency and visibility of tidal features and debris across a range of environments and stellar masses as well as their reliability as an indicator of galaxy accretion histories. We consider how observational biases such as projection effects, the point-spread-function and survey depth may effect the proper characterisation and measurement of tidal features, finding that LSST will be capable of recovering much of the flux found in the outskirts of L* galaxies at redshifts beyond local volume. In our simulated sample, tidal features are ubiquitous In L* galaxies and remain common even at significantly lower masses (M*>10^10 Msun). The fraction of stellar mass found in tidal features increases towards higher masses, rising to 5-10% for the most massive objects in our sample (M*~10^11.5 Msun). Such objects frequently exhibit many distinct tidal features often with complex morphologies, becoming increasingly numerous with increased depth. The interpretation and characterisation of such features can vary significantly with orientation and imaging depth. Our findings demonstrate the importance of accounting for the biases that arise from projection effects and surface-brightness limits and suggest that, even after the LSST is complete, much of the discovery space in low surface-brightness Universe will remain to be explored.
