This paper describes on the evaluation and management of work process in suction hopper dredger and grab bucket dredger as an application of a PC-based ECDIS system. The dynamic tracking of dredging bucket and the data logging of grab dredging information were performed by using the grab dredging vessel "Kunwoong G-18". The position and route tracking of the dredger moving toward the ocean dumping site of dredged material was performed by using the hopper dredging vessel "Samyang-7". The evaluation of wok process in the dredging field, for grab dredger, was continuously carried out on January to May, 2006, in Incheon Hang and for hopper dredger, on July to December, 2003, in Busan Hang, Korea. The dredging information, such as dredger's position, heading, dredging depth and route track which was individually time stamped during the dredging operation, was automatically processed in real-time on the ECDIS and displayed simultaneously on the S-57 ENC chart. From these results, we conclude that the ECDIS system can be applied as a tool in order to manage the work process during the dredging operation, and also in order to generate the factual record of the dredging activities that is sufficient for dredging inspector to accurately evaluate the contract performance even in the absence of a full-time onboard inspector.

A studies wish to present safety assessment table that is consisted of safety check-up, safety education, safety management for worker's safety management assessment about unit process. And safety management level was survey through case study that use safety assessment table. Safety management assessment table is improved safety management level of unit process, and is developed safety management system by worker confirms assessment items and improves problem.

Safety check-up and individual education, safety status wishes to present included safety assessment table for safety management assessment system construction about unit work process in Study. Safety management assessment table gives each grades about worker of unit work process, safety check-up, education, management and identifies merits and demerits of unit work process, it is that propose safety management assessment system that can reduce accident occurrence possibility.

The main objective of this study is to propose numerical guideline for the improvement of educational environment about high school girls. In order to analyze feature of the somatotype of the high school girls, analysis of this study was performed about 25 body parts such as height(7 parts), width(4 parts), thickness(4 parts), circumference(5 parts), length(4 parts), and body weight. For the specific comparison on body dementions, Mollison's comparison graph were used.

In order to apply job performance records to the master craftsman examination, which is an examination to screen the top-rated technician and task manager, the domestic industry has introduced job performance records to the written test of the master craftsman examination. Surveys on master craftsman's field capabilities and applicability are being conducted, and various qualification methods are being tested so as to give satisfaction to consumers in industrial fields. However, these methods have many problems in assessing task managers' qualifications. In order to solve these problems, this research intends to verify the appropriateness of introducing master craftsman's portfolios assessment and the suitability of application methods by conducting interviews and surveys. One big conglomerate and one mid-sized company that has more than 500 employees and covers from 주조(酒造:brewing) 또는 to providing various services to consumers were selected for this research.

Numerous studies have suggested that the traditional project management tools do not adequately support the coordination efforts required to successfully deliver projects. because they were not developed to control uncertainty which is one of the characteristic of construction project. In traditional construction process control, supervisor usually measures the quantity of production for the project schedule. Flow production has suggested that better productivity, like that labor and cost performance can be achieved by reducing work flows variability. This research has suggested that 1) the circular concept of productivity with work flows variation. 2) the indicators that quantitatively measure work flows variation using productivity data which is obtained from the document of construction field. 3) measurement of productivity-based work flows variation for analyzing correlation with variation of productivity and verifies.

Considering in view of China's low price and Japan's high technology, the most important point is the quality of product. To increase the comparative power internationally all workingmen have to fulfill the responsibility to maximize the quality, and this is possible practiced under 'Zero Defect' spirit. To reduce the defect ratio to 'Zero' the workingmen have to recognize own fault, all the manufacturing process should be conducted under 'Fool Proof System', If done under this circumstances, then labor force can work comfortably and safely without nervousness and tiresome. The productivity and quality can increase ultimately and even foreign labor, imbecile child, old-aged labor can participate in work, which can reduce shortage of labor source. Therefore, in this study all defects in manufacturing process, it would be recognized the errors and mistakes caused by human.

There are much dangerous machine in worksite. These make the rate of accidents increase. Specially, among them, the Press work has the highest rate of accidents. Therefore, it has been managed by Industrial safety-health law. It is very important to make a special study of work using the dangerous machine. In press work, it is also important to develop safety system program to improve productivity and work safely, In this reaserch, the safety management system is built for the work improvement of the Press. This paper showed method about dangerous machine.

There is much dangerous machine in worksite. These make the rate of accidents increase. Specially, among them, dryness equipment work has the highest rate of accidents. Therefore, it has been managed by safety-health law. It is very important to make a special study of work using the dangerous machine. In press work, it is also important to develop safety system program to improve productivity and work safely In this reaserch. the safety mangement system is built for the work improvement of the Press. I will try new development method about dangerous machine.

The study was purposed to know the status of prevention on health obstacle in industries with confined space. The results were as follows: 1. It was found 38% of respondents established health-work program in confined space. The percentage of respondents with instrument of oxygen sampling and equipment of ventilation, operation of safety and health education, posting of watching man and operation of head count were 42%, 35%, 75%, 46% and 56%, respectively. 2. The percentage of awakening of risk, confirm of air condition and operation of emergency training were 36%, 25% and 10%, respectively.

본 연구의 목적은 병원급식소의 세정작업의 효율적 관리를 위하여 위탁 전과 후의 비용효과를 비교하고 자가운영과 위탁운영체제의 세정담당 종업원들의 직무만족도를 비교하여 그 비용효율성을 분석하는데 있다. 본 연구의 결과에 의하면, 세정작업의 위탁관리로 다음과 같은 잇점을 기대할 수 있었다. 첫째, 호봉이 낮고 적은 수의 종업원 이용으로 인건비의 절감을 기대할 수 있었으며, 둘째, 봉급에 관한 항목을 제외한 다른 항목에 관해서는 자가운영과 위탁운영 체제의 세정담당 종업원들의 직무만족도에 유의적 차이가 없는 것으로 나타났으며, 세째, 작업일정이나 인사배치에 있어서의 용이함으로 나타났다. 이 연구 결과를 기초로 병원급식소의 위탁관리 프로그램에 관한 지속적인 평가와 개발에 관한 연구가 이루어져야 할 것이다.

해상 준설선을 이용한 항로의 준설시공 과정에서 중요한 점은 작업구역의 공간적 축소로 여유통항수역의 제공과 수면하의 위험물 배제로 안전항행을 제공하는 것이 기본이다. 이를 위해서는 준설선의 이동과 고정을 위한 보조장비의 적극적인 활용과 함께 부대 장비의 실시간 위치확인, 실시간 준설수심 확인 및 작업정보 등을 통합적인 정보로 제공하여 준설 작업의 자동화를 꾀해야 한다. 그런데, 본 연구에서 스퍼드 제어시스템을 비치한 준설선은 준설 시공시 준설구역 내 준설점 위치로 이동을 스퍼드로 하고 스퍼드는 자동제어 기술을 적용하여 준설선의 능동적 이동에 의한 준설시공을 행하여 최소의 작업공간을 점유하게 되므로 항행하는 타 선박의 안전한 통과를 허용하면서 준설공사를 중단 없이 시공할 수 있다. 또한, 스퍼드 활용 항로준설시스템은 스퍼드의 거동괘적은 물론 전자해도와 함께 작업심도 자료를 동시에 제공하므로 신속한 작업성과까지도 제시할 수 있다는 점에서 기존의 관리시스템과는 비교가 된다. 시스템 평가를 위한 부산항에서의 시험시공결과 일일 작업 시 기존의 앵카시스템을 이용한 작업시간의 2배정도를 실제 투입할 수 있었으며, 준설시공 요건별 비교에서도 준비시간을 38% 절감할 수 있었고 준비작업에 필요한 작업인력을 1인 줄일 수 있는 것으로 나타났다.
