The East Sea, a marginal sea or back-arc basin, consists of Japan Basin, Yamato Basin, and Ulleung Basin and is surrounded by the Pacific Plate and Philippine Sea Plate. Ulleung Basin locates in the southwestern part of the East Sea and shows the depth of 1,500 m in average and 2,500 m in maximum, connecting to the Japan Basin along 2,000 m contour. The slope of the seafloor is greater in the western side of the basin than in the southern and the eastern side. The crustal thickness of the Ulleung Basin from the OBS tends to get thicker toward the north and the west side and the sediment thickness of the Ulleung Basin is getting thicker toward the southeast side and reaches up to 12 km. The crustal type of the Ulleung Basin was variously suggested as like as a rifted continental crust, an extended continental crust, and an incipient oceanic trust. The origin of the crustal formation and the Ulleung Basin, however, is still controversial. Based on the bathymetry and gravtiy anomaly data for this study, the axis of the Ulleung Basin shows that the basin develops along the axis trending NW-SE direction and reveals a general symmetry of the bathymetry. And also the free-air gravity anomalies show a very similar pattern to the bathymetry of the basin. The sediment thickness is relatively thicker in the southeastern side of the basin than in the northwestern side. Although the crustal age of the Ulleung Basin is supposed to be younger than them of the Japan Basin and the Yamato Basin, the free-air gravity anomalies of the Ulleung Basin ranging -40 to 50 mGals are lower than the other basins, which suggests that the densities of crust and sediment of the Ulleng Basin are lower than the Japan Basin and the Yamato Basin.
Analyzing and Comparing Resilience Plans in Waterfront Cities: A Focus on Adaptation Strategies
김진호,Kim, Jinho Urban Science Institute 2023 도시과학 Vol.12 No.2
Facing the global crisis of climate change, waterfront areas are experiencing a significant increase in property damages and casualties. In light of the climate change era, this paper aims to identify resilience strategies against rising sea levels and associated natural disasters. A comparison and analysis of resilience plans and strategies have been conducted for five waterfront cities. In conclusion, three key points are suggested. Firstly, establishing partnerships locally and globally is an emerging trend to effectively and collaboratively address climate change. Secondly, resilience is a fundamental concept in designing social, built, and cyber infrastructure, requiring attention from stakeholders. Lastly, designing a well-operating system is critical to respond effectively when external shocks or stress occurs.

This paper proposes a method to measure the airburst height by utilizing a high speed camera. This method might be applied to the test of which flight target is alive after the burst. The proposed method consists of four main steps. The first step is to compute the impact point using the sea surface height. The second step is to compute the height of burst (HOB) by using the distance from the camera to the impact point. This could be different from the real explosion height. That is because the distance from the camera to the burst point is not the same as it from the camera to the impact point. Therefore, the third step is to calculate the approach angle of the flight target with respect to the installed camera. Then, the last step is to compensate the computed height by using the approach angle. The result of the proposed method is compared with it from the triangulation. In this paper, the HOB error is also analyzed regarding the approach angle difference. Based on this analysis, the camera position might be suggested for error reduction.
샤시부 주요 조인트의 TAY Spec.제정에 이용한 초음파 방식의 패스너 시험

This paper focuses on the fastener test of ultrasonic method applying TAY(Torque and Angle to Yield) specifications for Chassis’s critical joints. By contrast with the existing sensors for measuring tension-compression, Ultrasonic testing method is nondestructive test that is unnecessary to make test sample machined. Due to not machined test samples, the yield strength and prooflaod of bolts doesn’t become weaken. We can measure bolt preload for clevis-type joint by applying the ultrasonic testing method. Therefore, considering the advantages of ultrasonic testing method, it is highly recommended to use this test method for measuring tension data of clevis-type joint. Especially When determining ‘TAY(Torque and angle to yield) specification’ for the clevis-type joints, the ultrasonic method is highly appropriate for measuring the tension of jointed bolts without destroying the unique proof-load/yield strength.

The purpose of the study is analyzing combustion and emission characteristic in Heavy-duty SCDE (Single Cylinder Diesel Engine) with Mixer and LPi(Liquid propane injection) system. The Mixer and LPi system provides LPG in vapor and liquid phase throughout intake manifold. Sensors such as crank shaft position sensor (CPS) and hall sensor supply spark and injection timing data to the ignition controller. SCDE runs with engine speed of from 800 to 1400rpm, CR of 8, λ value 0.8 ~ 1.3. The major conclusions of this work include i) LPi and Mixer system are similar to BSFC as 275g/kw-h. ii) It is shown CO emissions are lowered as value is increased in rich condition.

현재 복사용지는 세계 곳곳에서 여러 제품들이 다양한 원료를 기반으로 생산 및 판매되고 있다. 복사 용지는 주원료인 펄프의 조성은 물론, 충진제나 지력증강제 등의 첨가제와 기타 제조방법에 따라 제품의 물성에 차이가 발생한다. 이런 종이의 물성 차이는 인쇄를 하는데 불량이 생기는 등 품질에도 영향을 미친다. 어떤 재료의 특성을 파악하는 다양한 분석 방법 중 적외선분광분석(infra-red spectroscopy, IR)은 적외선 파장을 이용해 유기물이 지닌 작용기를 파악하여 정성분석하는 방법이다. 한편, 다변량분석방법 중 하나인 주성분분석(principal component analysis, PCA)은 많은 변수들로 이루어진 데이터를 몇 개의 주성분이라는 이름의 주요 변수로 추출해내는 분석방법이다. 미대륙의 복사용지로 IR spectrum 데이터와 PCA를 활용하여 제조국 및 제조회사에 따라 분류가 일어나는 것을 확인한 사례가 있으며 또 여과지를 재료로 PCA분석을 이용하여 노화정도를 분석한 연구가 있었다. 본 연구에서는 아메리카 대륙의 3개국(미국, 캐나다, 브라질)과 유럽 3개국(오스트리아, 독일, 핀란드)에서 생산된 복사용지를 수집하여 ATR-IR을 이용하여 IR spectrum 데이터를 획득하고 Savitsky-Golay 알코리즘에 의해 전처리를 실시한 후, 주성분분석으로 각 복사용지 제품간의 분류 가능성을 확인하였다. 그 결과, 각 대륙별 복사용지들이 주요 특성에 따라 각각 클러스터를 형성하는 걸 확인할 수 있었다. 클러스터를 형성하는 복사용지들의 특성은 제조 원료, 충진제 및 제조 시기 등을 확인할 수 있는 IR 스펙트럼 내 작용기의 세기(intensity)를 통해 확인이 가능하였다.
