매우 복잡한 시스템의 보다 효율적인 설계를 위한 차세대 SoC를 위해 중요한 것은 시스템의 고적용성과 고확장성이다. 이를 위해 최근 들어 급속히 관심이 높아지는 것이 계산 모듈중심의 시스템 설계를 탈피하여 통신 중심으로 시스템 설계를 보는 communication-based 설계 방법론이며, 그 중 대표적으로 많은 관심을 모으고 있는 것이 Network-on-Chip (NoC)이다. 이는 모듈간의 직접적인 연결에 의한 데이터의 통신 구조를 가진 일반적인 SoC 설계에서의 취약한 확장성과 통신 구조의 고정성을 극복하기 위해, 데이터를 패킷화하고, 이를 네트워크 인터페이스 및 라우터에 의한 가변적인 구조에 의해 전송함으로써 통신 구조의 적용성과 확장성을 제공하려는 노력이다. 하지만 확장성과 적용성에 치중하다 보면 성능과 면적에 대한 비용이 너무 커져서 실제로 기존의 연결 방법과 비교하여 실용성이 없을 수 있다. 그래서 본 연구에서는 통신 패턴의 면밀한 분석을 통하여 매우 성능에 중요하고 또 빈번한 통신 패턴에 대해서는 기존의 연결 방식을 고수하면서, 전체적인 연결성 및 확장성을 유지하는 알고리즘을 제시한다. 이 방법을 통해서 최소 30%의 네트워크 인터페이스 및 라우터 구조가 훨씬 간단한 구조로 바뀔 수 있었으며, 이로 인한 연결성 (connectivity) 및 확장성에 대한 손실은 거의 없었다. 시뮬레이션 결과에 의하면 통신 구조의 최적화를 통해서 연결에 소요되는 시간적 성능은 49.19% 향상되었고 면적의 측면에서도 24.03% 향상되었음이 입증되었다.

연구는 최근 5년간(2006~2010) 서울시 행정동 단위별로 도시 홍수를 유발하는 기후요인, 홍수에 노출된 정도를 나타내는 민감도, 홍수피해를 저감하는 능력을 나타내는 적응도 요소들을 종합한 서울 도심지역의 홍수 취약도 지수의 공간적 분포 특징을 밝히고자 하였다. IPCC(Intergovernmental Panel on Climate Change) 취약성 모델에 기반을 둔 상관성 분석 결과 서울 도심의 홍수피해 건수는 여러 홍수취약성 관련 변수 중 빗물저류조 용량, 1일 최대강우량, 빗물펌프장 토출량 등과 높은 상관관계를 갖는 것으로 나타났다. 서울 도심지역의 홍수 취약도 공간분포도를 분석한 결과 안양천과 중랑천 등 도심하천 주변의 광범위한 행정동 지역에서는 공통적으로 높은 민감도가 홍수 취약도를 높이는 주요 요인임을 알 수 있었다. 특히, 중랑천 주변지역은 높은 민감도 이외에도 높은 기후요인에 의해 홍수 취약도가 높게 나타남을 알 수 있다. 국지적으로 홍수 취약성이 높게 나타난 강동구와 송파구 일부 행정동 지역에서는 적응도가 낮아 홍수 취약도가 높게 나타났고, 강남구 일부 행정동 지역에서는 극한강수현상과 같은 기후요인과 민감도가 높아 홍수 취약도가 상대적으로 높게 나타나고 있다. 이러한 고해상도 행정구역인 행정동 단위에서 도출된 홍수 취약성 분포도는 도심 내부의 지역별 적합한 홍수 대응, 관리 및 예방 정책을 수립하는 데 유용한 기초자료로 활용될 수 있을 것으로 예상된다.

The purpose of this study was to develop a list of plants that adapted to the aquatic environment in urban areas based on the list of plants surveyed through literature review and field surveys, and to classify the types of vegetation according to the five categories of plant distributions set by the U.S. Fish and Wildlife Service (1988) in the aspect of the adaptability of plants to the aquatic environment. Results of the classification by category according to the adaptability to the aquatic environment for the plant species surveyed through literature review and field surveys showed that there are 45 species of OBL, 96 species of FACW, 66 species of FAC, and 94 species of FACU, totaling 650 species. In addition, a total of 50 species excluding exotic species, endangered species, and naturally introduced plants are proposed as appropriate plants for the urban aquatic environment that will be artificially constructed. The results of the study can be utilized as the basic information for maintaining diversity and stability of the ecosystem during the restoration of water ecology; they can serve as useful data for the development of an optimum vegetation model when planting in water spaces in the future and preparing proper planting plans for each space. In addition, it is believed that the information will be useful in wetland identification and evaluation by observing plant species that appear only in wetlands.

Objectives : The aim of this study was to examine associations between quality of life in patients with schizophrenia and their family relationships. Methods : A total of 68 patients with schizophrenia participated in the study. Socio-demographic and clinical data were collected, as well as results from the Subjective Well-being under Neuroleptic Treatment Scale-Short Form(SWN-K), Family Emotional Involvement and Criticism Scale(FEICS), a visual analogue scale for evaluating the degree of perceived criticism(VAS), the Family Adaptability and Cohesion Evaluation Scale(FACES), Beck Cognitive Insight Scale(BCIS), and Rosenberg Self Esteem Scale(R-SES). Psychiatrists administered the Positive and Negative Syndrome Scale and the Calgary Depression Scale for Schizophrenia(CDSS), and collected a history of previous suicide attempts. Results : The SWN-K total scores showed significant negative correlations with scores on the FEICS perceived criticism, CDSS, and VAS measures and significant positive correlations with scores on the R-SES, FACES, and BCIS. Multiple regression analysis revealed that FEICS perceived criticism, FACES, and BCIS scores were significantly associated with SWN-K scores. The FACES total score was significantly lower in patients with a history of previous suicide attempt. Conclusion : The quality of life of patients with schizophrenia was negatively associated with greater perceived familial criticism and positively associated with better family cohesion and higher patient insight. In patients with a history of suicide attempts, family adaptability and cohesion were significantly low.

In responding to climate change in the agricultural sector, Climate Smart Agriculture (CSA) is an approach to establish a sustainable agricultural system through comprehensive management of technology, policy, and investment. The international community is continually expanding CSA implementation, and it became more important to understand the status of the domestic agriculture system and practices that are relevant to CSA. This study explored the available CSA in domestic agricultural systems and presented the order of relative importance of CSA technology. AHP analysis is employed for the evaluation with the following criteria: productivity, marketability, adaptability, and mitigation. The relative importance is evaluated with six agricultural technologies (soil, crop management, water, energy efficiency, alternative energy, and precision agriculture) in 28 agricultural technology sectors. The results of the AHP analysis showed that 'alternative energy' was found to be a top priority among the agricultural technology sectors, and 'shallow depth drain in rice paddy' was a top priority for agricultural technology. Also, the 'marketability' in soil and water sectors, 'mitigation' in crop management, and 'adaptability' in energy efficiency and alternative energy were given higher priority. The results of this study can be used as a good source for strategic CSA preparation and application.

The experiments were carried out in open experimental field of Field Crops Research Institute, Hai Duong, Vietnam in Winter Spring seasons 2015-2016 and 2016-2017 for finding high yielding of Korean chipping potato varieties which are adaptable to Vietnam condition. Six varieties of Korean potato (G1, G2, G4, G10, B1, B2) were experimented. The control variety (G6) was Atlantic which has long been a standard chip variety. The results showed that, for a hill, there was positive correlation between number of stems and number of tubers. The hill yield also showed highly relation to the plant height and number of tubers. Even though the growth and yield of potatoes grown in the season 2016-2017 were significant higher than these of potatoes grown in the season 2015-2016, their percentages of tubers infected by scab disease were much higher. This is probably because of irregular soil moisture content at the tuber forming duration. While G1, G6 and B1 are white flesh varieties, the remaining are yellow flesh varieties. There are two shapes types among experimented varieties: oblong (G1, G10, B1) and round shape (G2, G4, G6, B2). The total yields of varieties G1, G2, B1, B2 were higher than the total yield of the control variety from 16.5-49.4% in the season 2015-2016 and from 39.8-75.6% in the season 2016-2017.

This research concerns the effect of kaolin as material of cement admixture. which has the advantage of low price and high adaptability. Kaolin, a kind of soil, is well known as a raw material of pottery. which is widely scat-tered on the earth (especially in Korea). This research shows the method and process for activating kaolin to have the properties of a cement admixture through experiment. In the experiments, kaolin is baked in high temperature and then cooled suddenly to be activated. The temperature zone and time span, on which kaolin is activated are examined. The research looks over the effect of the activated kaolin based on several criteria regarding to chemical and physical characteristic of general admixtures. The results of this research are as follows; kaolin start activation at the temperature above 50$0^{\circ}C$ and make ends of activation at the temperature below 95$0^{\circ}C$ and there was little effect by the change of duration. It is concluded that compressive strength can be increased by putting activated kaolin in the concrete and the activated kaolin is good for water resistance and anti-chemical , and that it is effective for protecting the leakage of hazardous article like Cl- and for protecting damage by an organic salt like acid. The activated kaolin of proper temperature and time is effective in compressive strength, salt resistance and acid resistance. The adaptability of activated kaolin as a cement admixture was shown through this research.

One of the main shortcomings in the current passive base isolation system is lack of adaptability. The recent research and development of a novel adaptive seismic isolator based on magnetorheological elastomer (MRE) material has created an opportunity to add adaptability to base isolation systems for civil structures. The new MRE based base isolator is able to significantly alter its shear modulus or lateral stiffness with the applied magnetic field or electric current, which makes it a competitive candidate to develop an adaptive base isolation system. This paper aims at exploring suitable control algorithms for such adaptive base isolation system by developing a close-loop semi-active control system for a building structure equipped with MRE base isolators. The MRE base isolator is simulated by a numerical model derived from experimental characterization based on the Bouc-Wen Model, which is able to describe the force-displacement response of the device accurately. The parameters of Bouc-Wen Model such as the stiffness and the damping coefficients are described as functions of the applied current. The state-space model is built by analyzing the dynamic property of the structure embedded with MRE base isolators. A Lyapunov-based controller is designed to adaptively vary the current applied to MRE base isolator to suppress the quake-induced vibrations. The proposed control method is applied to a widely used benchmark base-isolated structure by numerical simulation. The performance of the adaptive base isolation system was evaluated through comparison with optimal passive base isolation system and a passive base isolation system with optimized base shear. It is concluded that the adaptive base isolation system with proposed Lyapunov-based semi-active control surpasses the performance of other two passive systems in protecting the civil structures under seismic events.
