This paper discusses the application of collaborative robots to the de-palletizing in IMC (Inte-grated Mail Center). The domestic courier logistics market has grown rapidly, and logistics centers are reaching critical capacity. Therefore, digital innovation based on logistics automation is necessary, and this paper looks at the factors to be considered when introducing collaborative robots and improvement measures considering the characteristics of the de-palletizing task. The benefits of introducing collaborative robots include immediate efficiency and the goal of assisting workers. The paper reviews related research and cases of collaborative robots applied to logistics centers and summarizes the results of collaborative robots introduced to actual postal logistics centers. The paper also provides a comparison of collaborative robots and industrial robots and presents four candidates for collaborative robots for logistics work. The paper also considers suction grippers to be mounted on the arm to grasp the parcel. The paper concludes by discussing the introduction of collaborative robots in the post office logistics center.

본 연구는 의약품 물류업체를 대상으로 물류센터 선정시 고려하는 요인들을 파악하고 그 요인들에 대한 중요도-만족도를 분석함으로 현재의 의약품 물류센터입지의 개선방안을 제공하였다. 첫째, 물류센터선정시 고려요인은 물류요인, 경제요인, 환경요인, 정책요인으로 구분되고 각 요인에 포함된 구체적인 속성들에 대해서는 대부분이 중요도에 비해 만족도가 낮은 것으로 나타났다. 둘째, 의약품 물류센터 이용자들은 생산업체, 유통업체, 병-의원, 약국으로 구분하고 각 이용자별 분석결과, 물류 요인은 개선이 필요하고 환경요인은 과잉투자된 것으로 확인되었다. 이러한 연구 결과는 향후 의약품 유통업체들이 물류센터를 선정하는데 있어 방향성을 제시해 줄 수 있으며, 전략적 시사점을 제공할 수 있을 것으로 기대한다.

본 연구에서는 적응형혼합유전알고리즘(Adaptive Hybrid Genetic Algorithm: AHGA) 접근법을 이용한 폐쇄루프 공급망(Closed-Loop Supply Chain: CLSC) 모델 최적화를 다루고 있다. CLSC 모델 구축을 위해 공급업체(Part Supplier), 제품제조업체(Product Manufacturer)등으로 구성된 전방향물류(Forward Logistics)와 수집업체(Collection Center), 회복센터(Recovery Center)등으로 구성된 역물류(Reverse Logistics)를 함께 고려하고 있다. 제안된 CLSC 모델은 수리모형(Mathematical Model)으로 표현되며, AHGA접근법을 이용해 이행되어 그 최적해를 구하게 된다. 수치실험에서는 기존연구에서 제안된 몇몇 접근법과 AHGA 접근법을 함께 사용하여 그 수행도를 비교분석하였다.

Purpose - In general, large companies have larger organizations, funds, and systems to provide more effective and efficient services in the market. However, development needs to support the livelihood of ordinary citizens who work for small businesses as well. This research suggests that a new distribution channel, called a "foothold style Kosa mart," that cooperates jointly with a distribution center and a large discount mart can provide direct solutions to small and mid-size distributors. This new distribution channel can achieve a limited type of "Nadle shop (small supermarket) foster project" related to building a joint distribution center and improvement in wholesale supply. Research design, data, and methodology - Data about the Korea distribution situation, the Nadle stores, and the logistics centers were collected from literature, Statistics Korea, journals, and reports. Specifically, we investigated information about Kosa Mart and Nadle stores. We focused on the redesign of the distribution center for the Nadle store. Results - The Kosa Mart distribution center now includes 18 warehouses, and has been handling 2000-3000 items. Most of the warehouses have been simply designed and items loaded and stored without refrigeration; thus, it is possible to store only products of certain manufactured goods. The current logistics center has no wholesale function because it failed to resolve the joint purchasing and product supply issues of competitively priced products. Conclusions - This study aimed to identify ways to strengthen the competitiveness of small- and medium-sized retailers. A Kosa Mart redesign aims to unifying the logistics center, stores, and customers. First, the joint wholesale logistics system, equipped with an integrated ordering system, needs to process customer orders and store orders at the same time. Second, excellent small business product development has to connect with production. Third, the store composition needs to support a shipping hub. Fourth, the Mart differentiates itself from convenience store goods by supplying regional and specialized products to customers. Fifth, a service buying agent and direct transactions between producers and consumers need to be established, and exhibits and displays of goods need to be improved.

During the fierce competition among the companies, improvement of logistics center managing efficiency is importantly recognized. Among them, studies on improvement of picking work process on about 55% of logistics center managing costs are continuously conducted. And, most of studies focus on analysis on strengths and weaknesses of picking method performable on the stage of logistics center design, etc, so the purposes of this research are to define load location rule by product releasing frequency in logistics managing environment based on conveyer and suggest expected effects by simulation analyzing method to improve picking managing efficiency.

부산항 신항 배후단지에는 56개 물류센터가 운영되면서 개장 초기 대비 많은 수의 물류센터 운영과 전반적인 산업 경기 위축으로 물동량이 다소 감소하고 있다. 이로 인해 물동량 유치를 위한 물류센터 간 경쟁이 일어나고 있는 상황이다. 본 연구에서는 이러한 시장 상황에서 물류센터가 구비하고 있는 여건은 대동소이하므로 화주들은 물류센터를 결정하는데 있어 저단가 외에 어떠한 차별화 된 서비스를 원하는지 실증분석을 통해 알아보고자 한다. 현재 물류센터의 서비스품질과 관련한 연구는 부족한 실정이다. 이에 본 연구에서는 기존의 서비스품질 이론을 물류센터에 적용하여 물류센터 서비스품질의 요인을 구성하고 이들 요인이 물류센터 서비스에 대한 고객만족과 구전의도 및 재이용의도에 어떠한 영향을 끼치는지를 분석하였다. 분석 결과 물류센터 서비스품질은 유형성, 신뢰성, 공감성, 확신성, Know-How의 5가지 차원으로 구성되었으며, 회귀분석 결과 이들 요인은 고객만족에 유의한 영향을 미치는 것으로 분석되었다. 또한, 인지된 고객만족은 구전의도와 재이용의도에 유의한 영향을 미치는 것으로 분석되었다.

PDK1 is essential for T cell receptor (TCR)-mediated activation of $NF-{\kappa}B$, and PDK1-induced phosphorylation of $PKC{\theta}$ is important for TCR-induced $NF-{\kappa}B$ activation. However, inverse regulation of PDK1 by $PKC{\theta}$ during T cell activation has not been investigated. In this study, we found that $PKC{\theta}$ is involved in human PDK1 phosphorylation and that its kinase activity is crucial for human PDK1 phosphorylation. Mass spectrometry analysis of wild-type $PKC{\theta}$ or of kinase-inactive form of $PKC{\theta}$ revealed that $PKC{\theta}$ induced phosphorylation of human PDK1 at Ser-64. This $PKC{\theta}$-induced PDK1 phosphorylation positively regulated T cell activation and TCR-induced $NF-{\kappa}B$ activation. Moreover, phosphorylation of human PDK1 at Ser-64 increased the stability of human PDK1 protein. These results suggest that Ser-64 is an important phosphorylation site that is part of a positive feedback loop for human PDK1-$PKC{\theta}$-mediated T cell activation.
