Busan port's main function is handling container cargo compared to world major ports and the percentage of handling general cargo such as dirty bulk cargo is very low. In other words, although total cargo weight of Busan port that recorded the handling result of 13.29million TEU in 2008 reached 113.05million ton, total cargo weight of general cargo was 15.31million ton, so container cargo accounted for 88.1% of whole cargo weight. However, it is the time to create high added value by the increase of handling and marketing dirty bulk cargo. Originally, the dirty bulk cargo was not the avoided object from the first. Somehow, it is a very high added value cargo, and is surely essential strategic material to basic industries of nation. However, it becomes dirty bulk cargo as the companies are reluctant to handle it because of environmental problem, distinct characteristic in handling, uncertain break even point due to imbalance between supply and demand compared to container cargo. However, items that are classified as dirty bulk cargo now are certainly necessary strategic materials to national basic industries or national life. Besides it seems to be a high added value cargo here and now. Therefore, it is time that increasing of handling dirty bulk cargo by marketing it and the system for efficient handling such as constructing the exclusive use wharf in Busan port, modernizing of facilities and equipments, stable secure of place for holding and handling through development of distribution complex by item, efficient data processing and closer cooperation by setting up a SCM of related authorities are needful.

This study analyzed the chemical accidents of hydrochloric acid which is the most frequent chemical in order to make safety management improvement plans. 28 Cases have occurred for the last 4 years, 8 cases of which were casualty accidents, and more efficient plans are needed to minimize the accidents. For this purpose, this study investigated the problems through yearly statistics of the chemical accidents, and suggested appropriate measures of facility management, safety culture and management plans. It is important for businesses to make and implement the improvement measures according to time schedule.

The intervention area located at rear hot cell can be contaminated by hot cell maintenance work. For effective decontamination of the intervention floor a wet type decontamination device was developed. The device was assembled with a brush rotating part, a washing liquid supplying part, an intake part for recovering contaminated liquid and a device moving cart part. The device was made of stainless steel for easy decontamination and corrosion resistance. The function test carried out at intervention area of the PIE facility showed good performance.

In order to decrease the number of handles, speed up retrieval operations, and manage products efficiently, the investment of facilities such as the installation of the storage equipment and the enlargement of the storage area may be attempted. However, the same objectives can be accomplished by utilizing the existing storage area efficiently. In many types of storage facilities, because of the limitation of storage areas, products are usually piled up, which may cause rehandles of inventories. Rehandles influence significantly the handling efficiency of warehouses. This study develops methods for minimizing rehandles of inventories to improve the operational efficiency of warehouses. A mixed storage problem is addressed for minimizing the expected number of rehandles. Optimization models are proposed and the genetic algorithm is applied to solve the problem.

Although hydrazine is an excellent liquid propellant, caution is required during storage and handling due to its high toxicity and reactivity. Safety guidelines should be established in consideration of the chemical reactivity by unintended leakage. In this study, the status of hydrazine facilities at launch site and safety standards for storing and handling were investigated and then, the reactivity between chemicals and hydrazine was analyzed. As a result of the analysis, hydrazine has reactivity with the exception of fuel oil. This paper emphasizes the imperative nature of constructing a dedicated hydrazine storage facility. Ensuring compatibility between hydrazine and the materials used in storage containers and handling equipment is crucial to prevent undesired reactions that could compromise safety. It was intended to be used as basic data to secure the range safety when handling hydrazine.

The Korea Radioactive Waste Agency plans to expand the storage capacity of radioactive waste by constructing a radioactive waste inspecting building to solve the problem of the lack of inspection space and drum-handling space in the radioactive waste receipt and storage building for the first-stage disposal facility. In this study, the exposure doses of radiation workers that handle new disposal containers for decommissioning waste in the storage areas of the radioactive waste inspecting building were calculated using the Monte Carlo N-particle transport code. The annual collective dose was calculated as a total of 84.8 man-mSv for 304 new disposal containers and an estimated annual 306 working hours for the radiation work. When the 304 new disposal containers (small/medium type) were stored in the storage areas, it was found that 25 radiation workers should be involved in acceptance/disposal inspection, and the estimated exposure dose per worker was calculated as an average annual value of 3.39 mSv. When the radiation workers handle the small containers in high-radiation dose areas, the small containers should be shielded further by increasing the concrete liner thickness to improve the work efficiency and radiation safety of the radiation workers. The results of this study will be useful in establishing the optimal radiation working conditions for radiation workers using the source term and characteristics of decommissioning waste based on actual measurements.

One hundred and forty-four cross-bred market pigs weighing approximately 110 kg were randomly divided into four groups in a 2 (handling stress; minimal vs stimulated) ${\times}$ 2 (transport vehicle type; enclosed box vs conventional open) factorial arrangement of treatments. The stimulated handling stress group received overally rough handling including electric prod stimulation during loading, transport and lairage at least once at each step. All the animals received 3-h lairage prior to slaughter. Blood and longissimus dorsi muscle (LM) samples were taken at slaughter and after overnight chilling of the carcass, respectively. Plasma concentrations of stress indicators glucose, cortisol, creatine kinase and lactate dehydrogenase were greater in the stimulated vs minimal handling stress group. There were no interactions between the handling stress and transport vehicle type in their effects on these blood variables. The incidence of pale, soft and exudative (PSE) carcass and drip loss of LM, 24-h postmortem LM pH and color including the lightness and redness were not affected by the handling stress and transport vehicle type. In conclusion, results suggest that rough handling inflicts a stimulated stress on the animal, which is manifested by increased blood concentrations of stress indicators, and therefore should be avoided for animal welfare.

본회는 지난달 12일부터 19일까지 5박7일의 일정으로 한형석 본회 회장을 단장으로 네덜란드, 벨기에, 독일 등 3개국의 도계 및 닭고기 포장시설을 시찰했다. 총 22명으로 구성된 이번 시찰단은 닭고기 포장유통 의무화에 맞춰 정형화된 외국의 시설을 둘러보기 위해 마련되었으며 도계 및 포장기계 설비회사인 Meyn社, Systemate社, 그리고 Stork社의 도움으로 진행되었다. 닭고기 포장유통은 단순히 포장으로만 진행되는 것이 아니라 사전준비 작업인 칠링(닭고기의 온도를 낮추는 시설)의 중요성이 대두되면서 포장시설과 함께 도계시설을 중점적으로 점검하게 되었으며 이와 함께 부분육 가공공장도 둘러볼 기회를 가지게 됐다. 이번에 방문한 도계장은 모두 에어칠링 시스템을 갖춘 곳이며, 도계장에 대한 전문지식이 부족하여 간략하게 방문한 회사의 개요만 설명하고자 한다. 처음 방문한 도계장은‘Clazing’이라는 회사로 시간당 1만5천수를 작업하는 규모이다. 작업물량은 2㎏ 이상의 산란 노계전문처리장이며 닭을 부위별로 절단∙처리하는 컷업전문 처리장이다. Flandrex 도계장 역시 노계전문 처리장으로 닭을 부위별로 분할, 아프리카 등지로 수출을 하고 있으며 시간당 9천수 정도를 작업한다.‘Klaassen푸드’는 2000년도에 세워진 도계장으로 시간당 9천수를 작업하며 부분육을 생산 벌크로 포장하여 주로 도매상중 원료육 취급업자에게 공급하고 있다. ‘Broviand社’는 닭가슴살 등을 전문으로 발골하는 회사로 시간당 6천수를 발골하며 햄버거 패티 등 가공원료로 전량 납품하고 있다. 앞서 소개한 Clazing社등에서 분할된 부분육을 발골하는 것으로 보여졌다.‘Flschgefluge社’는 독일에 위치한 회사로 원래는 사료회사를 운영하다가 도계장을 하게 된 경우로 수평계열화체계를 갖추고 있는 것으로 보인다. 시간당 1만2천수를 작업하며 95%를 부분육으로 생산, 전량 포장하여 마트 등으로 유통시키고 있다.
