  • Purpose: This study identified the standardization activities from the early stage of acquisition to disposal during the materiel life cycle and proposed the improvement of standardization process. Methods: Through improvement of duplicated deliberation for the revision of military specification, unification of technical change proposal reception organization, and resolution between the conflicting parts of laws and regulations, simplifying the standardization procedure and strengthening linkages between the civilian standards were gained. Results: We have redefined the concept of the standards and standardization in the field of defense and proposed the standards-driven documentary standards as a measurement standards and reference standards to expand the activities. Conclusion: Through a standardization survey, we came to conclusion that we need to change the concept of standardization in the field of national defense from making the specification to using the means of efficient management of military resources.

  • A man model can be used as an effective tool to design ergonomically sound products and workplaces, and subsequently evaluate them properly. For a man model to be truly useful, it must be integrated with a posture prediction model which should be capable of representing the human arm reach posture in the context of equipments and workspaces. Since the human movement possesses redundant degrees of freedom, accurate representation or prediction of human movement was known to be a difficult problem. To solve this redundancy problem, a psychophysical cost function was suggested in this study which defines a cost value for each joint movement angle. The psychophysical cost function developed integrates the psychophysical discomfort of joints and the joint range availability concept which has been used for redundant arm manipulation in robotics to predict the arm reach posture. To properly predict an arm reach posture, an arm reach posture prediction model was then developed in which a posture configuration that provides the minimum total cost is chosen. The predictivity of the psychophysical cost function was compared with that of the biomechanical cost function which is based on the minimization of joint torque. Here, the human body is regarded as a two-dimensional multi-link system which consists of four links ; trunk, upper arm, lower arm and hand. Real reach postures were photographed from the subjects and were compared to the postures predicted by the model. Results showed that the postures predicted by the psychophysical cost function closely simulated human reach postures and the predictivity was more accurate than that by the biomechanical cost function.

  • Prestressed concrete (PSC) I-type girders have been used for span length around up to 40 m in domestic region. PSC girders are very cost effective girder type and extending their lengths more than 50 m will bring large benefit in cost. A new design method was proposed by combining two notable design concept in order to extend the applicable span length in this study. First of all, several numbers of openings was introduced in the girder web, and half of the anchorage devices were moved into the openings. In this way, large compressive stress developed at end zone was reduced, and the portion of design load coming from self-weight was reduced as well. Secondly, prestressing force was introduced in the girder not once at the initial stage, but through multiple loading stages. A full scale girder with the length of 50 m with the girder depth of 2 m was fabricated, and a flexural test was conducted in order to verify the performance of newly developed girder. Test results showed that the new holed web design concept can provide a way to design girders longer than 50 meters with the girder height of 2 m.

  • Data envelopment analysis(DEA) has proved to be powerful for benchmarking and has been widely used in a variety of settings since the advent of it. DEA can be used in identifying the best performing units to be benchmarked against as well as in providing actionable measure for improvement of a organization's performance. However, the selection of performance benchmarks is a matter of both technical production possibilities and organizational policy considerations, managerial preferences and external restrictions. In that regards, DEA has a limited value in benchmarking because it focuses on only technical production Possibilities. This research proposes a new perspective in using DEA and a frame-work for benchmarking to select benchmarks that are both feasible and desirable in terms of organizational context. To do this, the concept of local and global efficiency is newly proposed. To show how useful the suggested concept and framework are, a case study is addressed.

  • ASME BPVC provides stress evaluation rules for Class 2 and 3 nuclear piping. However, such rules are difficult to be applied to reinforced wall-thinned pipes during service. To resolve this issue, a new method for stress evaluation of reinforced wall-thinned pipes is proposed in this work, based on the equivalent stiffness concept. By converting a reinforced wall-thinned pipe to an equivalent straight pipe having the same stiffness, stress evaluation can be proceeded using the current ASME BPVC rules. The proposed method is applied to pipes with 4 different normal pipe size and the effects of reinforcement and wall-thinning dimensions on evaluated stresses are discussed.

  • It has been generally agreed that the city form especially in the preindustrial age resembled their own world view, either in the western or the eastern cultural sphere. So, we aimed to redefine the characteristics of oriental world views compared with the western one, in order to find the relative nature of the Korean townscapes. It is said that the both world views(of western and oriental) are composed of the contrastive binary concepts in common, but there seems to have been nearly contrary differences in these two world views. Wheareas the former was based on the passively segregational and oppositional dualism, the latter, on the dynamically harmonious and complementary dualism, called generally as 'Yin(陰) and Yang(陽)'. Thus, the oriental world view can be thought as the 'philosophy of the relationship', which aim to unify the dualism ultimately with the help of this relationship. So, we can assume a certain third and intermediate concept between these dual concepts of the world view, which can unify these two into the one holistic whole. And the focuses of the most traditional oriental philosophies were concentrated on this, so called, 'the third concept', namely Taoistic 'Tochu(道樞)', Buddhistic 'Kong(空)' or Confucian 'Chung(中)'. And this triple concept, including the third one, of the oriental world view revealed a more concrete form of the cosmological relationship, as the triple structure; 'Heaven(天), Earth(地), and Man(人)', in which the 'Man' is thought as the middle or the center of the world. In this manner, we could found this oriental 'triple world view' was revealed in the real topology of most places in the Korean traditional city and the whole townscape itself. So, in the scale of houses and the roads around them, we can construe the 'Maru(a central board-floored room)' and the 'Madang(a inner court)' as the 'third and intermediate space(中)' between the interior space(陰) and exterior space(陽) in the former, and between the private house(陰) and the public residential road(陽) in the former case, and between the dual parts(陰,陽) of the city representing the contrary social classes and the contrastive visual landscapes. So, we insist that this 'triple world view' represented in the townscape can be one of the most important characteristics of Korean traditional townscape. And this third intermediate spaces, which generate the active social contact and the harmonious relationship among the people, can be the most important cues, as the central places, in the interpretation of the Korean townscapes even in contemporary circumstance, which inherits its spatial and social frame more or less from the preceding one.

  • 이 글은 "계몽주의 시대의 '철학자/작가'의 시기별 개념 변화와 그 의미 - 1. 용어의 사전적 의미와 18세기 문학장의 기원"의 후속 논문이다. 우리는 이 글에서 출판시장이 확대된 이후 17세기 말엽의 문학장의 변화를 고찰했다. 특히 현대철학자들과 교수직을 가진 전통 철학자들 간에 철학자로서의 정체성을 두고 벌어진 다툼의 양상이 이 글의 핵심내용이다. 이를 통해 새로운 독자층의 형성으로 인해 전통 철학자들도 독자들의 기대지평에 민감했다는 사실을 확인했다. 몇몇 전기 작품도 이 글의 관심사항이었다. 17세기 말 갑자기 예전과 달리 철학자나 작가가 전기 작품의 대상이 되었기 때문이다. 우리는 이에 대한 연구를 통해 독자들은 새로운 시대를 선도할 새로운 영웅, 즉 위대한 철학자 또는 위대한 작가의 도래를 희구했고, 이러한 희망이 전기 작품의 출판으로 이어졌음을 밝혔다. 이 과정에서 저자, 작가, 철학자 등에 대한 개념변화가 자연스럽게 드러났다. 다음 글에서 우리는 철학자/작가에 대한 보다 진전된 논의를 이어갈 것이다.

  • The series of ‘Dubonnet’poster is one of the masterpieces of Cassandre who was the leader of advertising poster in 1920's and 1930's. Orihinally it was a triptych, but it was developed as a serial work later through lettering and seasonal advertising posters. It was kept in circulation for more than two decades and issued in a variety of formats. In this thesis I tried to figure out the artistic character and uniqueness of Cassandre's poster by analyzing it with many different points of view of the poster, the stream of changing style and influence from the Avant-garde painting. In chapterII, objectively analyzing the series of‘Dubonnet’one by one, I examined the method that Cassandre used to deliver the concept of advertising and his message. The triptych, the first one of series of Dubonnet poster is witty, the slogan is a pun using the words dubo(doubt), bon(good), and Dubonnet, and the theme is treated as an animated sequence in the manner of a comic strip. In the following winter and summer seasonal advertising posters, the‘Dubonnet man’in the same position is enjoying the‘Dubonnet’, irrespective of the hazards of climate and season, There was a change towards 1929 that rectilinear design gave place to supple and undulating lines in Cassandre's posters. Seasonal advertising posters also showed the change, and the tendency of realistic and concrete elements of an expression was strengthened. In chapterIII, I studied three as main characters of Cassandre's poster. The first one is simple and geometric expression, second one is uniqueness of figures and the last one is important roll of lettering. Cassandre believed that there were fundamental differences between the function of a poster and that of a painting. He also recognized that the symbol was the essential element in the poster design, which would be simply and swiftly recognized. The recognition led him to simple design and bold geometric abstraction. He was a man who knew the value of copy in advertising and developed it fully in his simplified geometric compositions by integrating of letterforms and image. The‘Dubonnet man’is geometrized, almost featureless. This approach of rendering human beings was one that Cassandre had used from the early years, most notably in his posters for Dubonnet.
