The process basket assembly is an important module in pyroprocess, because pyroprocess is a batch process, so process materials are contained in a basket assembly and transferred with the basket. The basket assembly is composed of upper and lower assembly. The lower assembly is a basket or crucible which contains process materials, and it can have electrodes. The upper assembly mainly consists of heat shields, a flange, and connectors for supplying currents to electrodes of the lower assembly. During the electrolytic recovery process, the lower part is submerged into molten salt, whose temperature is about 500°C at least and the heat from salt is transferred to the upper assembly. And the heat affects the performance or durability of parts on the top of equipment and can raise cell temperature, which is an undesired situation. In addition, the handling equipment can pick the assembly when it is hottest, and during the transfer, the gripped part is under thermal and mechanical stresses. Because of this, the thermal effects from the heat should be required during equipment design stage. In this study, the thermal analyses of process basket assembly were conducted for 3 cases: the steady state of the basket assembly when it submerged in molten salt, the thermal and mechanical stresses when gripped by remote handling device, and the temperature changes under natural convection. These analyses were performed using Solidworks with flow simulation package, and the results will apply to improve the thermal resistant performance of the basket assembly.

담관 담석을 제거하기 위해서는 선택적 담관삽입술(selective cannulation)에 성공한 뒤 내시경 유두괄약근 절개술을 시행하게 된다. 내시경 유두괄약근 절개술은 출혈, 천공, 췌장염 등의 합병증을 발생시킬 수 있다. 이러한 합병증의 발생을 줄이고 시술의 성공률을 높이기 위하여 다양한 형태의 내시경 괄약근 절개기와 절개를 위해 사용되는 전류 발생기가 개발되었다. 또한 절개의 방향과 범위, 절개술에 대한 가이드라인이 정해지고 있다. 괄약근 절개 후 담석의 제거를 위해 사용되는 방법에서 대표적으로 풍선을 이용하는 방법과 바스켓을 이용하는 방법이 있다. 내시경 괄약근 절개술의 기술적 방법을 소개하고, 효과적으로 담석을 제거할 수 있는 대표적인 방법들에 대하여 임상적 적응증과 기술적 방법에 대하여 논하고자 한다.

Some euryalid specimens were collected with fishing nets from Mipo, Gyungsangnamdo and Aewol, Jejudo Island, Korea. They were identified as Gorgonocephalus eucnemis (Müller & Troschel, 1842), belonging to family Gorgonocephalidae of order Euryalida, which was new to the Korean fauna. Their molecular analyses were done with newly intended COI primers of mitochondrial cytochrome oxidase I (COI) gene for the accurate molecular identification. The Korean G. eucnemis was coincident with this NCBI species as a result of Blast analysis, which showed the 99% similarity. In the current study, three Gorgonocephalus species have been reported from Korea.

Currently, the harvest is achieved by manpower of laborer and recently, the bulk of laborers are almost old people and women. In addition, due to the inconveniences of using harvest baskets and the percentages of labor in harvesting are high, in this research the harvest basket is designed for using in harvest. The basket is designed by consideration of the physical condition, it is analyzed about the effects of the weight and strain on the harvest basket by using the structure analysis. As a result, underside of basket occurs largest deformation. And the back of basket occurs lower deformation than underside of basket.

In this study, It is assumed that customers are both usage unit of spare parts and stores of displaying and selling the goods that are installation unit of having the spare parts. The demand pattern through the effective order of spare parts and issue lis

월성원자력본부의 조밀건식저장시설인 MACSTOR/KN-400의 인허가 과정에서 사고조건에 대한 바스 켓의 안전성 평가를 위한 실증시험의 필요성이 제기되었다. 실증시험을 위한 낙하시험시설을 한국원자력 연구원에 설치하고 바스켓 낙하 실증시험을 수행하였다. 실증시험 결과 실린더 내 적재 바스켓의 상부 용 접부가 낙하 바스켓과 충돌하여 파손되고 누설이 발생하였다. 기존 바스켓이 실증시험에서 누설율 성능 요건을 만족하지 못함에 따라 바스켓의 설계 개선안 도출이 필요하게 되었다. 설계 개선을 위한 방향을 선정하고 이에 기초하여 6 종류의 설계 개선안을 도출하였다. 개별 설계 개선안에 대하여 구조해석 및 시편시험을 수행하였다. 구조해석 및 시편시험의 결과를 바탕으로 최종설계안을 확정하였다. 최종설계안은 바스켓의 중앙 포스트의 높이를 감소하여 낙하 바스켓과의 충돌속도를 감소시키는 설계안이었다. 최종설 계안에 대한 시험모델을 제작하여 낙하실증시험을 재수행한 결과 모든 성능요건을 만족하였다.

Purpose - The study was designed to explore and examine the business relationships of the owners and the employees of Market Basket to analyze the implications of their recent turbulence and decisions. This article focused on two issues - business profit and labor union - to describe the uniqueness of this case. Design, methodology, data, and approach – This article, based on its purpose, applied all three approaches of case studies that are identified and described by Stake (1995), instrumental, intrinsic, and collective, to present the core nature of the issue and to improve and gain a clear understanding of this particular phenomenon. Results – The analysis of this case clearly indicates that seemingly dichotomous concepts of profit and employee welfare are not necessarily antithetical to each other Conclusions – The instant case of Market Basket serves as a testimonial for the rejection of the basic premises of corporate profits and labor unions. This case serves as a model and a practical example for many large retailers, especially the family operated retailers, and workers throughout the world.
