본 연구는 우리나라의 네 해역(전북, 신안, 제주, 울산)을 대상으로, 주풍향 산정 방법에 따른 해상풍력단지 내부후류 및 연간 발전량의 민감도를 분석하였다. 이를 위해 ERA5 재해석 시계열로부터 3 m/s 이상 풍속의 출현빈도 기반 지표와 풍력에너지밀도에 의 한 총에너지 기반 지표를 산정하고, 가중 조합을 통해 다섯 가지 주풍향 시나리오(Sc1-Sc5)를 정의하였다. 각 사이트에는 15 MW급 터 빈 32기를 4×8 행렬로 배치하고, 행렬 장축을 시나리오별 주풍향에 정렬한 후, Vortex MAPS 중규모 자원과 TurbOPark 후류모델을 이 용하여 행별 풍속 저감률과 내부후류 손실을 평가하였다. 그 결과, 단순 빈도 기반 주풍향(Sc1)이 모든 해역에서 가장 큰 내부후류 손 실과 낮은 연간발전량을 보였으며, 총에너지 기반 주풍향(Sc5)으로 갈수록 단지 중심부의 풍속 저감률이 완화되고 P50 AEP가 증가하 는 경향이 확인되었다. 특히 풍속 출현빈도와 총에너지 간 지배풍향 차이가 큰 제주 서부 해역에서 민감도가 가장 크게 나타났다. 본 연구는 우리나라 해역 특성을 반영한 주풍향 산정 및 해상풍력단지 배치 전략 수립에 유용한 기초 자료를 제공한다.

본 연구는 도시공원녹지의 공간적 형평성과 서비스 균형성을 평가하기 위한 지표를 탐색하고 공원 조성의 효과를 객관적으로 평가함으로써 도시 녹지 계획에 이론적 근거를 제공할 수 있는 자료 획 득을 목적으로 시도되었다. 이를 위해 네트워크분석법과 공간구문론을 기반으로 중국 산둥성 옌타 이시 중심 지역의 공원을 대상으로 다양한 교통수단 하에서의 접근성과 사용자 관점에서의 전역 및 국지 접근성을 분석하였다. 분석 결과, 푸산구는 전체적인 도로망이 더 통합적이고 연결성이 높아 전역 접근성이 가장 높은 것으로 나타났다. 또한, 즈푸구와 푸산구의 국지 접근성은 1.6km 서비스 반경 내에서 가장 높게 나타났으며 이들 지역의 국지적 도로망은 중심성과 통합성이 높은 구조를 보였다. 접근성의 불균형은 주로 공원의 수와 위치의 공간적 분포가 불균형하고 인구 밀도 와의 적합성이 낮으며 일부 공원의 접근성 수준이 공원 유형과 일치하지 않는 데에 기인한다. 본 연구를 통해 공원의 종합적 접근성을 향상시키고 녹지 공간 배치를 최적화하기 위한 방안으로는 중소형 공원의 추가 조성과 주거 지역을 주요 수요지로 고려하며 지선 구조와 대중교통 체계를 개 선하는 등의 전략을 제안하고자 한다.

In the fourth year of the Hongwu era of the Ming Dynasty (1371), Chengdu was restructured as the Chengdu prefecture. It continued to serve as the political center of the Sichuan region, and the city was rebuilt on a large scale. During this time, additional Ming official offices were established, and a feudal lord's residence was set up to govern the city jointly. Compared with the previous dynasty, the city construction techniques of the Ming Dynasty were more mature, and the institutional system was gradually standardized. While implementing the Ming system, local officials incorporated early city-building concepts from the Zhouyi and Zhouli, influencing Chengdu's spatial pattern with ideas and systems from the Central Plains. The topography of the basin in which Chengdu was located also provided favorable natural conditions for the completion of the city form. This also helped to fully display the idea of city building in the city's space. Due to the frequent wars in the middle and late Ming Dynasty, Chengdu's cities and buildings have not been preserved to this day. Therefore, Based on historical documents and local chronicles, this research explores the spatial structure of Chengdu during the Ming Dynasty and the Yixue and etiquette embodied in the city's construction. On this basis, the ten most important royal residences of the early Ming dynasty were selected as objects of comparison, and their internal architectural forms were analyzed to provide supplementary evidence for the institutionalization of Chengdu and the residences of the Shu kings. Furthermore, the cities were compared with the Taiyuan Mansion in Shanxi, which had considerable political significance, to analyze differences in spatial organization and institutional expression from the perspectives of urban layout and etiquette expression. Finally, based on ancient images and archaeological data, a detailed analysis of the spatial structure of Chengdu City during the Ming Dynasty was conducted. The characteristics and key features of the city's gates, facilities, and construction methods were summarised to provide new insights into the spatial development of Chinese cities during the Ming Dynasty.

In the present study, to investigate the seismic behavior of a cabinet under earthquakes, three types of mass blocks (top load, center load, and bottom load) were selected as the cabinet's internal structure, and the vibration characteristics according to the load arrangement were studied. The internal structure simulates the device modules installed inside the cabinet. The cabinet's modal characteristics and response spectrum were evaluated under the three types of loads. Six modes, displacement, and acceleration responses for each load were analyzed. The analysis results showed that mode 1 had the lowest frequency, and that the frequency increased by approximately two times as the mode increased. The change in natural frequency according to load placement was confirmed through modal analysis of the cabinet. The cabinet's displacement and acceleration were greatest in the x-axis and lowest in the y-axis. Displacement and acceleration according to the load distribution at the top, center, and bottom were within a certain range, so the vibration characteristics of the internal structure of the cabinet were limitedly affected.

The demand for automated diagnostic facilities has increased due to the rise in high-risk infectious diseases. However, small and medium-sized centers struggle to implement full automation because of limited resources. An integrated molecular diagnostics automation system addresses this issue by integrating small-scale automated facilities for each diagnostic process. Nonetheless, determining the optimal number of facilities and human resources remains challenging. This study proposes a methodology combining discrete event simulation and a genetic algorithm to optimize job-shop facility layout in the integrated molecular diagnostics automation system. A discrete event simulation model incorporates the number of facilities, processing times, and batch sizes for each step of the molecular diagnostics process. Genetic algorithm operations, such as tournament, crossover, and mutation, are applied to derive the optimal strategy for facility layout. The proposed methodology derives optimal facility layouts for various scenarios, minimizing costs while achieving the target production volume. This methodology can serve as a decision support tool when introducing job-shop production in the integrated molecular diagnostics automation system

According to literature, Chengdu was built in the ancient Shu period, and Chengdu experienced nearly 3,000 years of history in this region. After the city was founded in the Qin Dynasty, there were never any natural disasters such as floods in Chengdu for more than 2,000 years. Although there were no natural disasters, due to its central location in the southwest of China, wars were frequent. Thus, how to effectively suppress the rebellion in the southwest and how to rebuild the city after the wars became the top attention of the governments of Chengdu in the successive dynasties. At the beginning of the Qing Dynasty, the government followed the Yuan and Ming systems, and the layout and architectural style of the city was similar to the previous dynasties. With the gradual recovery of the economy, Chengdu became a military center in southwest China and a military base was built in the city. Since then, Chengdu has gradually broken the original city style. Therefore, in this study, through archeological and literature sources, we analyzed the spatial structural evolution of Chengdu city in the historical background, focusing on the urban space and major building structures of Chengdu during the Qing Dynasty, which was relatively rich in information.

공항은 다른 어떤 기반시설보다 복잡하고 사고시 매우 치명적이기 때문에 공항 계획/설계시 운영적인 측면을 고려한 면밀한 검토가 필요하다. 공항 건설이후 실제 항공기가 어떻게 운영되는지 시뮬레이션하고 문제점을 사전에 예측함으로써 항공기 운항 안전성을 확보할 수 있기 때문이다. 최근 도로/공항의 경우 디지털 트윈 기반의 시뮬레이션 프로그램으로 설계, 분석하는 사례가 많다. 이러한 기조에 맞춰 공항에서도 시뮬레이션 프로그램인 AviPLAN을 활용하여 에어사이드 배치 설계를 수행하고 있으며, 인천국제공항공사와 한국공항공사에서도 활용하고 있다. 본 연구에서는 기존 국내외 공항에 AviPLAN 프로그램을 활용하여 최적화 설계를 수행하였고 산출된 포장물량 절감사례를 바탕으로 에어사이드 시설 배치가 얼마나 중요한지 확인하고자 하였다.

PURPOSES : A model for minimizing cutting loss and determining the optimum layout of blocks in pavements was developed in this study. METHODS : Based on literature review, a model which included constraints such as the amount, volume, overlap, and pattern, was developed to minimize the cutting loss in an irregular pavement shape. The Stach bond, stretcher bond, and herringbone patterns were used in this model. The harmony search and particle swarm algorithms were then used to solve this model. RESULTS : Based on the results of the model and algorithms, the harmony search algorithm yielded better results because of its fast computation time. Moreover, compared to the sample pavement area, it reduced the cutting loss by 20.91%. CONCLUSIONS : The model and algorithms successfully optimized the layout of the pavement and they have potential applications in industries, such as tiling, panels, and textiles.

Before the 15th century, the main buildings of the residences of the ruling class in Seoul consisted of Momchae(身梗), Seocheong(西廳), and Naeru(內樓)‧Chimru(寢樓). Based on the equality of the relationship between husband and wife, the couple lived in the main building[Momchae] in the center of the mansion, but based on the individuality of the relationship between husband and wife, each had an area consisting of the same section within the building. Naeru‧Chimru was the two floors bedroom building became a common living space for the minister and wife, upstairs in summer, downstairs in winter. In preparation for large gatherings and important receptions, an open-structured West Hall(西廳) was located on the west side of the mansion. Momchae, Seocheong, and Naeru‧Chimru were the common building types and layouts of the residences of the highest ruling class, including high-ranking officials, until the reign of King Sejong. However, from around the time of King Seongjong, Seocheong and Chimru came to be regarded as privileged and luxurious buildings only allowed for the grand prince's residence. The layout of the bedroom, main building (including Wings), Outer Sarang[外舍廊], and Joyangru[朝陽樓] of Prince Bongrim's mansion built in the first half of the 17th century clearly shows the transitional period when the arrangement of chimru, main building, and western office was disrupted and the layout changed to the Inner main building(Anchae for wife) and Outer main building(Sarangchae for husband).

In the late Joseon Dynasty, the floor of the royal palace was covered with grass mat called ji-ui. Ji-ui was produced by connecting several mats named seokja(席子) and trimming the edge with narrow fabric named seon (縇). The standard manufacturing technique was to connect the shorter sides of the seokjas by overstitching them. A room was covered with either single or multiple ji-uis, depending on the case. In the case of the main and the subsidiary halls (jeong-jeon and pyeon-jeon, respectively) where the king conducted official meetings with the civil servants, multiple ji-uis were laid out to signify the division of space, which reflected the ceremonial aspects of the governing acts. The most essential division was the distinction of yeong-wae(楹外) and yeong-nae(楹內), with the jeon-goju (a tall frontal pillar inside the hall) functioning as the breakpoint. Jeong-jeon was divided into four spaces each covered with one ji-ui: yeong-nae, yeong-wae, and the left and the right sides of the royal seat named jwa-tap(座榻). Pyeon-jeon was covered with three ji-uis that divided the hall into three spaces: yeong-nae, yeong-wae, and hu-twae(後退) (the hind section) where the royal seat was placed on.

The Sijeon (Licensed Markets) legally permitted by the government along the Jongno and the Namdaemunro Avenues played a central commercial role in Hanyang. However, after the opening of the port in the late Joseon era, the Licensed Markets suffered a blow and declined due to the introduction of a new product of civilization and the appearance of foreign merchants. Although the Licensed Markets, which have been maintained without major changes for a long time, have played a major role in the urban spatial structure, the exact location has not been still determined, and researches until now has remained limited for such that. In this study, based on the 1912 land survey records, the location of the Licensed Markets pre-and post- 1910 is identified, and the spatial change of the dismantling process is investigated.
