This paper describes a real-time manufacturing scheduling system on Internet using DBR(Drum-Buffer-Rope) scheduling method. We intend to change company-oriented manufacturing scheduling, which has been used at most manufacturing companies, to customer-oriented manufacturing scheduling. Customers can not only choose product kinds, quantities and order due dates, but also evaluate optimum order due date by themselves in real-time through internet and then the results will be converted into practical manufacturing scheduling. If the company cannot meet the customer order due date, it will offer reliable and accurate information to the customers by suggesting the earliest order due date. To evaluate the customer order due date in real time, companies should be able to estimate their accurate production capacity. This research uses Goldratt's DBR scheduling method to realize that function. The DBR scheduling does not recognize the production capacity of the whole company, but only of the constraint resources which have a great effect on the company throughput. Thus, it can improve the customer service level as well as the profit by performing more dynamic and reliable scheduling through Internet.

The present study investigated what combination of three form-focused options - explicit explanation, production practice, and corrective feedback - may be effective in helping low-proficiency learners improve accuracy in communicative writing. The subjects were 34 Korean university students enrolled in 'Business English 1' and the study lasted 11 weeks. The relative clause structure was selected as the target structure. The study found that the combination of explicit explanation, sentence-level production practice, communicative writing practice, and recasts had a significantly greater effect on improved accuracy than the combination of communicative writing practice and recasts and that of explicit explanation, communicative writing practice, and recasts. Because the second and third combinations didn't lead to significantly improved accuracy, it can be concluded that of the form-focused options forming the first combination sentence-level production practice made a decisive contribution to the significant increase in accuracy. It also found that the provision of self-correcting opportunities before providing recasts on errors committed in sentence-level production practice resulted in significantly greater accuracy in communicative writing than the provision of recasts alone on them. The results of the study suggest that we should make low-proficiency Korean learners have sentence-level production practice which is intensive and focused and make them self-correct targeted errors before providing them with narrowly focused recasts in order to help them to improve writing accuracy.

As the conventional farming emphasizes the productivity and the quantity produced, large amount of agricultural chemicals have been used. As a result, natural environment and human health are critical issues in recent years in Korea. Reflecting these problems, many farmers have begun to practice the LISA(low input sustainable agriculture) voluntarily across the country. In this study, a survey was made to 13 apple producers who have been producing the fruits by practicing the LISA, and wanted to analyze the production and marketing information in order to suggest the improvement strategies for the sustainable agriculture. Some of the improvement strategies were suggested as follows ; First, advance payment to the LISA apple growers should be supplied in order to make it easier for the financially burdened producers. Also, some kind of means should be developed to prepare the equipments/machineries to make the organic fertilizers. Price differentiation should be utilized in marketing the products, and mass marketing channels for the LISA products should be provided for them. Public quality guaranty is badly needed in order to accelerate the marketing. Finally, stronger producer organizations should be organized and subsidized by the government because those organizations are playing an important role in developing the LISA.

The study is to suggest easier making method of skirts and slacks as to compare production process between manufacturers and references of clothing construct in universities. Skirts and slacks have simple production process and they are basic subjects in clothing construct class. But most references have just contents which are to make basic styles of skirts and slacks made basic materials. Continuous development of new material and variety of style request more efficient and easer making method in the reference of clothing construct. So the making methods of references and manufacturers are compared and analyzed in this study In references, there are many hand work and sub-work because they are for a person who make own clothes. In contrast, manufacturers have to product many variety clothes of good quality for many people and think the production cost of clothes. They use more simple and efficient method that include their know-how to meet changing fashion situation. In making methods of skirts and slacks, differences between references and manufacturer are in sewing of waist band and zippers and location of interlining. Manufacturers use variedly sewing method of waist band according to material and their experience. Especially handling for wrong side inseam of waist band is distinct between references and manufacturers. References have basic and detail work and manufacturers know processing order having even grade work to keep continuous production. The making method of clothes have to change and improve according to the situation. The more useful making method get to include their merits and references need to add more practical method and knowledge.

This paper explores the current situation of the broadcasting program production by video journalists (VJs), one of the recent trends of broadcasting production, centering around the programs made in Daejeon. The result of the survey shows that VJ programs are considered to be one of the generalized broadcasting program production systems. Thus, production costs should be γeadjusted to a realistic level in order to secure the good quality VJ programs in the current situation. Local broadcasting stations should depart from the idea that they make a VJ program subcontract to produce programs at low cost. It is time to support good quality VJ programs financially and systematically. The survey also reveals that most video journalists cannot participate in the decision-making process regarding program production. Local broadcastings should cooperate with video journalists, as co-producers, in producing the programs. Besides, VJ programs have some disadvantages such as limitation of high definition image production, poor image quality, instability of images taken, etc Hence, video journalists should also try to make better image quality of their broadcasting programs. Local subcontractors should make efforts to overcome their poor manpower and production environments as well. By economizing their scale of production and updating their production equipment, subcontractors need to constantly develop the contents related to local community which make them more competitive.

Capacity planning plays an important role not only for master production plan but also for facility or layout design in shipbuilding. Product work breakdown structure, attributes of production resources, and production method or process data are associated in order to make the discrete event simulation model of shipyard layout plan. The production amount of each process and the process time is assumed to be stochastic. Based on the stochastic discrete event simulation model, the production capacity of each facility in shipyard is estimated. The stochastic model of product arrival time, process time and transferring time is introduced for each process. Also, the production capacity is estimated for the assumed master production schedule.

To shield the radiation, we can make use of various materials, but the scattered rays can be caused by the shielding materials. The degree of the scattered rays production is influenced by the nature of the shielding materials and the energy of the radiation, therefore to choose the proper shielding material is the most important matter in radiation protection. Authors made an experimental study on the scattered rays generated from the shielding materials, and obtained the results as follows: 1. In the ranking of the scattered rays production: Cement bricks, black colored fire bricks, and red colored fire bricks were marked the first the second, and the third ranking respectly, and the last order was lead plates. 2. In the relative ranking of the scattered rays production by energy increase: Lead plates were marked the first order, the next and third order were red colored fire bricks and black colored fire bricks respectly, and cement bricks were marked the last order. 3. The scattered ray ratio of lateral-back point per lateral point were generally decreased by energy increment. The diminishing orders were that lead plates were the first order, and the next and the third order were red colored fire bricks and black colored fire bricks respectly, cement bricks were marked the last order.
