  • Among the Additive Manufacturing (AM) technologies, the Binder-Jetting printing technology is a method of spraying an adhesive on the surface of powder and laminate layer by layer. Recently, this technique has become a major issue in the production of large casting products such as ship-building, custom vehicles and so on. In this study, we performed research to make actual mold castings and increase mechanical property by using special sand and water-based binders. For use as a mold, it has a strength of more than 3MPa and permeability. Various experiments were carried out to obtain suitable them. The major process parameters were binder jetting volume, binder types, layer thickness and heat treatment condition. As a result of this study, the binder drop quantity was measured to be about 60 pico-liter, layer thickness was 100㎛ and the heat treatment condition was measured about 1,000℃ and compressive strength were measured to be more than 5MPa. The optimum condition of this experiment was established through actual casting of aluminum. The equipment used in this study was a Freeforms T400 model (SFS Co., Ltd.), and the printing area of 420 * 300 * 250mm and resolution of 600dpi can be realized.

  • The purposes of this study were to identify the actual utilization condition of combi-steam ovens and to evaluate the importance and the satisfaction of dietitians and cooks who used the oven in school foodservice. A survey of 300 schools, 1 dietitian and 1 cook from each school respectively; total 600, was conducted and 202 completed questionnaires were available for the purpose of the statistical evaluation. The main results of this study were summarized as follows: Among the schools, 70.5% set up the oven during 2007~2009, the most commonly used cooking method was 'Baking (87.0%)' and the way of acquiring recipes for the oven was 'from oven manufacturing company (50.0%)'. The advantage of using the oven was 'the convenient use of the oven (63.3%)' and the disadvantage was 'Difficulty of cooking foods evenly (59.8%)'. The degree of importance and satisfaction on twenty six attributes were measured according to type of school, location of school, number of meal service per day, and number of total serving per day. Among quality attributes of importance of the oven utilization, 19/18 characteristics were assessed over 4 point (important) out of 5 scale by dietitians/cooks respectively and in satisfaction 16/18 were over 4 points (satisfied) by dietitians/cooks respectively. When it comes to the most satisfied factor of combi-steam oven, 'Improvement of cooking baked foods' was highest for dietitians (4.60 point) and 'Checking temperature of cooked foods' was for cooks (4.49 point). In overall satisfaction of the oven use, the average score was 4.10 point for dietitians, 3.98 point for cooks out of a 5 point scale. Using the survey results as a base, school foodservices are required to use the combi-steam oven efficiently to serve high quality of meals for students.

  • In order to evaluate the exact effect of detergency it is necessary both to measure the actual soil content by chemical analysis and to determine the degree of soil removal visually. Since it takes considerable time and effort to use both methods, usually one of the two methods is used. Many studies have been carried out through increasing the visibility of oily soil to evaluate detergency by measuring reflectance of fabrics. In this study Sudan Black B, an oil soluble dye was used as an indicator to increase the visibility of oily soil on cotton and polyester fabrics. The condition of artificially soiled fabrics and the method of evaluating detergency were investigated which represent the actual detergency of oily soil by measuring the reflectance only. Also the detergency of Sudan Black B and that of oily soil were compared with each other under various washing conditions, As a result, the K/S values converted from the reflectances showed a good correlation with the actual soil content. Linear relationship between K/S value and the actual soil content was obtained. The K/S values of washed fabrics were higher than those of unwashed fabrics which included same content of soil since the soil visibility changed during washing. But the difference was small when Sudan Black B was used. With the increase of soil content, detergency of cotton fabric decreased, but detergency of polyester fabric increased gradually. With regards to soiled fabrics, detergency of cotton fabric measured by K/S value was close to that of actual oily soil when Sudan black B was used as an indicator.

  • INCOTERMS have been changed almost every 10 years since ICC established INCOTERMS as trade terms for International transaction. Recently transportation has become bigger, and modernized by means of electronic appliances such as RFID, IT, and containerization. FRC, FOR/FOT, FOA were added in INCOTERMS1980 and every conditions are unified into three alphabets in INCOTERMS1990. The best features of INCOTERMS2000 are that FCA substitute FRC, FOR/FOT, FOA and customs formalities were simplified to make clear for each party of contract. It seems that business circles still stick to old customs of their trade like FOB or CIF not only in Korea but in an international practice even though there have been several revisions of INCOTERMS until now. ICC have tried to provide INCOTERMS3000 to solve problems between a theory and an actual condition of international trade. This study has tried to suggest opinions against INCOTERMS3000 and has surveyed a recognition, an actual using situation and issues of INCOTERMS to get improvements. For a recognition of INCOTERMS has been spread as you can find at tables many kinds of business circles still stick to old customs of their trade terms FOB and CIF. Now there are two alternative plans. Firstly, we need to suggest improvements against inconsistency of INCOTERMS to be applied on newly revised INCOTERMS3000 and educating business circles to use proper conditions of INCOTERMS for their doing business. Secondly, we shall participate in revising INCOTERMS to activate multimodal transport conditions of INCOTERMS and provide solutions to fill gap between a theory and an actual condition of international trade. It seems that terms of multimodal transport such as FCA, CPT, or CIP can be a perfect condition for each party of contract. We have examined the inconsistent features of Ship's rail and notions of on board, and observed how to activate multimodal transport terms. These would be hot issues of next revision of INCOTERMS and we provided improvements on each trade terms, THC charges, or others against INCOTERMS.
