  • On the bases of the 5 principles and the 4 criteria for designing and developing of the listening and the reading test of National English Ability Test (NEAT), this study presents Item-Types Decision-Making Model as a blueprint for designing and constructing the two tests. It sets up the criteria for validating item types, designs a modular type of test specifications, constructs an item-types bank, and specifies a complementary type of test specifications of the two tests. To gather all these threads up, it constructs Item-Types Decision-Making Model which consists of such components as the item-type pool, the validity criteria and the procedures of testing item types, the item-types bank, the modular and the complementary type test specification. Thus, it shows how the Model works in developing and constructing the two level-differentiated listening and reading tests (the 2nd and the 3rd rank) of NEAT. Finally, it discusses some implications and applications of the Model to the two level-differentiated tests (the A and the B type) of 2014 CSAT (College Scholastic Ability Test) systems, National Assessment of Educational Achievement (NAEA), and classroom testing. In conclusion, Item-Types Decision-Making Model functions as a testing template in an item development system and as a matrix in an item-types bank system.

  • This paper is concerned with the question of servicing warranties for repairable items. During the warranty period, each time an item fails the manufacturer has the obligation to restore the item to operational condition either by repairing the item or by replacing it with a new item. In this paper, we consider repair-replacement strategies based on the condition of the failed item. For products with phase-type lifetime distributions where the phases represent the condition of the item, we develop algorithms to determine the expected cost of servicing a warranty and use it in making the repair-replacement decision. Illustrative numerical examples are presented. We also propose a dynamic strategy by taking the expected remaining warranty cost into consideration.

  • Cell type packaging line is more suitable for the products with various models and small quantities like mobile phone or mp3 player than conveyor type packaging line. Cell type packaging line is applicable to package various product models, but it can cause wrong product compositions and missing of items. So, automatic missing item detection system is needed. We designed an missing item detection system with a bar code reader, infrared sensors, and s digital camera. and also developed the programs for sensor data acquisition, image data processing, GUI, and data management.

During the warranty period, each time an item fails the manufacturer has the obligation to restore the item to operational condition either by repairing the item or by replacing it by a new item. In this paper, we consider a warranty policy for making this decision based on the condition of the failed item. For products with phase-type lifetime distributions where the phases represent the condition of the item, we develop algorithms to determine the expected cost of servicing a warranty and use it in making the repair/replacement decision. illustrative numerical examples are presented.

  • This study uses comparison tests of bodice basic patterns to research improvements in wearing evaluation methods based on differences in bodice basic patterns and body size. As study methods, we calculated body sizes for six types by selecting four types of bodice basic pattern and utilized bodice basic pattern size measurement tools. The study result are as follows. First, as the result of analyzing bodice basic patterns per each part and body size difference by bodice basic pattern size measurement tool, shoulder angle cover rate was J&K type 57.57%~68.41%, N type 53.13%~65.57%, L type 51.87%~63.73%, and H type 59.03%~68.20%. In the item of neck base circumference, it was J&K type 6.4~-16 mm, N type 10.7~-31.9 mm, L type -5.2~-13.4 mm, and H type -6.2~-15.4 mm. In the item of armscye circumference, it was J&K type -18.9~-59.4 mm, N type -15.2~-51.3 mm, L type -38.9~-52.7 mm, and H type -17~-42.2 mm. In the item of biacromion length, it was J&K type 23.2~-4.7 mm, N type 18.4~-10.4 mm, and H type 3.5~-5.7 mm. In the item of interscye back, it was J&K type and N type 17.6~-13.6 mm, L type 11.9~-13.6 mm, and H type 3.2~-11.8 mm. The item of interscye front was found in the sequences of study type and L type. Second, the Kruskal-Wallis test result (according to bodice basic pattern) indicated meaningful differences in items of shoulder angle cover rate, neck point to breast point, bust point-bust point, biacromion length and armscye circumference and H type had an overall higher rank.

  • The purpose of this study is to analyze the body type and fashion of posthuman in SF movies. The method of this study was to analyze documentaries, internet web site, fashion books and so forth. The results were as follows: The body types of posthuman were expressed as mutation type, prosthetic type, clone type by biological hybrid or renovation and digital type by computer simulation. The mutation type was expressed as reinforcement of masculinity or feminity and reinforcement of body functions. The fashion item was expressed as a black tailored suit, leather jacket, cat suit, whip, black sunglass, garter belt, high heel shoes, short pants, black one piece dress and functional body suit. The prosthetic type was expressed as reinforcement of body functions and reinforcement of masculinity or feminity. The fashion item was expressed as a military item, high-tech power suit and ergonomic armor suit. The clone type was expressed as the plural ego with reinforcement of body functions. The fashion item was expressed as a power shoulder jacket, fake fur coat, vinyl, black see-through look and functional suit. The digital type was expressed as reinforcement of masculinity or feminity and the plural ego with reinforcement of body functions. The fashion item was expressed as a data suit, leather jacket, black over coat, boots, black sun glass, ethnic items and military items. The meanings of posthuman fashion in SF movies were impurity of posthuman, display of superhuman's power by sexuality, metaphor of power and fantasy of superhero in opposition futuristic dystopia. As mentioned above, posthuman body type and fashion in SF movies become the conversational topic in the real world. The fact that we think about utopia and identity of posthuman in the future is of great significance.

  • 이 연구의 목적은 본 연구는 영재선발도구로서 지필 검사 문항의 적합성에 대한 검토를 위해 초등과학영재교육원의 학생 선발에 지난 3년간 사용된 지필 검사 문항들을 대상으로 문항 분석을 하여, 영재교육 대상자 선발 방법에 대한 새로운 전형방식에 주는 교훈을 얻기 위하여 실시하였다. 문항 분석 결과, 평균 문항 난이도와 변별도는 대체로 양호한 편이었으며, 교과 및 내용별로도 큰 차이가 없는 것으로 분석되었다. 서술형 문항이 객관형 문항에 비해 어렵게 출제되었으며, 변별력이 높았던 것으로 분석되었다. 특정 문항들과 총점과의 상관관계에서 객관형 문항의 경우는 물질 문항과, 자료변환 및 자료해석 문항에서 가장 높은 상관이 나타났으며, 서술형 문항의 창의성 문항이 총점과의 상관이 가장 높은 것으로 분석되었다. 선발 시험에 응시한 학생들의 성별의 따른 차이를 t 검증으로 분석한 결과, 자료변환 및 자료해석과 창의성에서 남학생의 평균이 유의미하게 높은 것으로 나타났다.

  • This study examines the relative competitive position of korean fisheries products market over period of 2001 to 2005 and selects strategic exported goods from its position provide against concluding FTA agreement with China and Japan. The portfolio approach is used to develope competitiveness-market share matrix. The position of each export countries on the competitiveness market share matrix will be in one of nine cells, with differing implications for their role in korean fisheries products market. Based the competitiveness market share matrix, each export countries are divided into first cell type, third cell type and ninth cell type and the items of ninth cell type are chosen as strategic exportable goods. The results of this study are summarized as follows: First, in the case of each country change aspect, China is trending to decrease quantity but shows number of item that increase gradually with high share still, and look trend that increase third cell type item too gradually, and in case of first cell type item is that competitive position is high more relatively than the Korea. In the case of Japan, ninth cell type item is falling gradually, and share does not show big change generally in case of first cell type item. Second, in the case of strategic exportable goods that analyze using domestic competitive position cell type and MCA with competitive position in domestic fisheries products market and export market, was appear by codfish(frozen), cuttle fish(frozen) etc. in case with China, and by mackerel(frozen), other sea bream(frozen), laver(dry), bathing(dry) etc. in case with Japan. And analyzed goods that have all export competitive advantages in both countries are roes of alaska pollack(frozen), other roes of fish(except frozen roes of alaska pollack), squid(frozen) etc.
