The global halal market is forecast to grow at an annual average of 5.2 percent from 2017 to $3.07 trillion in 2023 due to the high growth rate of the world's Muslim population, the spread of halal-certified food consumption and the economic growth of the Muslim world. Through this study, the difficulty of obtaining halal certification can be overcome through accurate understanding of the general supply chain and other halal supply chain. Also, by examining the trends and requirements of halal logistics standards in countries with advanced halal logistics systems, halal logistics certification agencies, and halal port logistics, we can help establish our own halal logistics system by finding areas that can be benchmarked in Korea and differentiated from those that can be found. For the safe supply chain management of halal products between logistics Supply Chain, an integrated logistics system shall be developed to manage customs and customs as one-stop, while maintaining a complete halal condition on a series of logistics processes such as storage, transportation, customs clearance, etc. Korea, entry into the halal logistics market through halal integrity guarantee solution or platform development can also be considered, taking advantage of the strength of IT and packaging.

Load/Unload(L/UL) technology includes the benefits, that is, increased areal density, reduced power consumption and improved shock resistance contrary to contact start stop(CSS). It has been widely used in portable hard disk drive and will become the key technology for developing the small form factor hard disk drive. The main objectives of L/UL are no slider disk contact or no media damage. For realizing those, we must consider many design parameters in L/UL systems. In this paper, we focus on the effect of the ramp profile. We can find out the lateral velocities in L/UL process through experiments and simulations for force of voice coil motor and friction force on ramp. And then, we will gain the optimal design of ramp slope to maintain the minimum clearance of suspension dimple and slider with FE model. In special, after finding the point at which air bearing breaks and designing the ramp, we will identify the results for improving unload performance.

The seismically isolated nuclear power plants shall be designed for design basis earthquake (DBE) and considered to ensure safety against beyond design basis earthquake (BDBE). In order to limit the excessive displacement of the seismic isolation system of the seismically isolated structure, the moat is installed at a certain distance from the upper mat supporting the superstructure. This certain distance is called clearance to stop (CS) and is calculated from the 90th percentile displacement of seismic isolation system subjected to BDBE. For design purposes, the CS can be obtained simply by multiplying the median displacement of the seismic isolation system against DBE by scale factor with a value of 3. The DBE and BDBE used in this study were generated by using 30 sets of artificial earthquakes corresponding to the nuclear standard design spectrum. In addition, latin hyper cube sampling was applied to generate 30 sets of artificial earthquakes corresponding to maximum - minimum spectra. For the DBE, the median displacement and the 99th percentile displacement of the seismic isolation system were calculated. For the BDBE, the suitability of the scale factor was assessed after calculating the 90th percentile displacement of the seismic isolation system.

본 논문에서는 주행 중 운전자가 브레이크 페달을 조작할 경우, 차량 후미의 브레이크등과 연계되어 점등됨과 동시에 차량의 감속 정도에 따라 점등되는 영역이 단계적으로 점멸되며 표시되는 속도 감응형 차량용 브레이크등 시스템을 구현하여 실험적으로 확인하였다. 뒤따르는 후방 차량이 선행차량의 감속상태를 더욱 쉽고 빠르게 인지시킴으로써 선행 차량의 급정거에 따른 추돌 사고를 예방할 수 있으며, 후방 차량의 신속한 대응을 이끌어낼 수 있다. 또한 초음파 센서를 이용하여 차간 거리가 일정 거리 이상으로 가까워지는 경우, 부져와 함께 비상등이 켜지며 후방 차량의 운전자에게 상황을 전달한다.

현재, 단지 내 진출입 불허구간의 설치 및 운영에 대한 명확한 설치기준이 없어 교통소통과 안전에 많은 문제가 발생하고 있는 실정이나, 단지 내 진출입 불허구간에 관한 연구는 미흡하여 합리적인 설계가 이루어지지 못하는 실정이다. 이에 본 연구에서는 단지 내 진출입 불허구간을 진입부와 진출부로 분류하여 진 출입부 적정길이를 산정하였다. 진입부 적정길이 산정은 횡단보도 위치 및 정지선 이격거리와 2차로 진입차량 대기행렬 길이, 안전을 고려한 여유거리 등을 고려하여 산정하였으며, 진출부 적정길이 산정은 횡단보도 위치 및 차량길이와 가로교차로 진출차량의 행태를 고려하여, 조사지점과 거리별로 진출부 차간간격을 비교 분석하여 산정하였다. 이와 같이 단지 내 진출입 불허구간을 대상으로 차량행태 조사와 교통소통 및 안전을 고려한 진출입 불허구간의 적정길이를 제시함으로써, 향후 단지 내 진출입 불허구간의 적합한 설치기준 및 운영에 이바지할 것으로 판단된다.
