The purpose of this study was to improve productivity for maximum effects with the present equipments and staff. This study compared and analyzed the mea-sured time by using stop watch method and MTM, which was the new measuring method. The flow and results of this study were as follows: 1. This study investigated the theoretical background the efficiency for production management, and the way of productivity improvement through documentary research. 2. Setting up the standard flow on the experi-mental company production, making out a process chart and measuring the actual working hour. 3. The study measured the allowance time applying work sampling. 4. Each process of the movement analysis was filmed by video to use basic data. 5. MTM analysis was taken by choosing 10 processes from front bodice according to the basic movement of MTM. Through the results, this study exclude unneccesary movements and suggest a method for working ways. 6. Using the actual working hour measured by a stop watch calculated the pitch time and presumed the amount of daily productivity. 7. The result of the work sampling came out as 38% of allowance rate. It was 13% higher than the standard amount of woman's jacket allowance rate, which was 25%. The most influencing factor was work discussion. That was because there were commuication problem of the work way between the operator and leader. More adequate use of flow table and level passing table was needed. There were the problems that inappropriate places and sizes made the distance of movements longer and often needed more adjustment of works and surroundings. To prevent breakdowns equipments check ups were necessary before works. 8. The results of MTM analysis were as follow : the time was reduced 40% than the actual measured time by a stop watch. This was because the leveling of the operator was included in the real calculation. Also, leveling was included in MTM analysis and all the conditions were standarized. Therefore MTM method was a scientidic measuring way of establishing the standard time. The presented method of this study, suggested an ideal method eliminating unneccesary motions, and presented standardization of works. Improvement of working methods, work condition and simplifying motions in each 10 processes reduced the working time from total 656 seconds to 301 seconds. 9. The way and time of working was linked together in the MTM analysis methods. Thus data from MTM help suggest not only establishing standard time but also establishing stan-dard work. Plus it includes various ability for improvements of working ways. So it is an objective method which can be widely used in other work studies. 10. The function of a time study is to determine the amount of work produced with a given method. The work rate is used to establish the cost of labor. The wage of worker must be calculated per unit time which is deter-mined before the time study is made. This study tried to introduce the incentive rule for deciding wages according to the standard time by MTM method.

The modern period was the time that the most radical and extensive social and mental changes were occurring throughout the history, and modernism was prevailing as a general cognition system of people. Modernism, which carries principles of progress, belief in application of scientific technology, worship of reason, ideal of liberty as a col-e value of civilization, was plated as a leading ideology in the realm of society, culture and art In the early 20th century. In this study, the formative characteristics of modernism seen in architecture and fashion are analogized and analyzed in four ways ell the basis of the theory of p. Greenhalgh. First, 'Standardization for mass-production', which is analogized which P. Greenhalgh's 'Decompart-mentalisation', 'Social Morality', and' Technology'. Standardization for mass-production in architecture focuses on the development of a design prototype in order to mass produce; the development of ready-made clothes is actively done ill the fashion area for the same purpose as well. Second, 'Rational functionality' coming from P. Greenhalgh's 'The total work of art' and 'Function'. While rational functionality in architecture puts an emphasis on the rational operation of all the functions in regard to the relation between each part and the whole, rational functionality in fashion call be mainly seen in a dramatic increase in physical activity which could be hardly found before the modernism period. Namely, all the fashion design elements are developed for a certain rational and functional design on each part as well as on the whole in order to greatly increase physical activity. Third, 'the pursuit for genuineness of objects and universality of beauty' is on the analogy of P Greenhalgh's 'Truth', 'Anti-historicism', 'Abstraction', 'Internationalism/Universality'. This idea is adopted in architecture in the form of design of geometrical abstraction. In the same way, design using geometrical abstraction comes to have a significant meaning in fashion of the modernism period. So to speak, modernism architecture and fashion can be reborn to become an inter·national style by giving up the decorative and regional design prevailing before modernism and by expressing universal aesthetics in the form of simplicity and abstraction instead. Fourth, 'Expression of progress through a change in a viewpoint' stems from P. Greenhalgh's 'Progress', 'Transformation of Consciousness', 'Theology'. In architecture, this concept appears by using new construction materials and methods and by representing new aesthetical idea. As a result, it makes it possible for people to make progress for better lives. Like in architecture, new attempts for material application and processing are made in fashion. This gives rise to a general change in a viewpoint related to fashion, so that a flew fashion design which there has never been before can come out.

빅토리아 시대로부터 오늘날까지 수많은 의자들이 디자인되었다. 토네트의 1859년 No.14의자, 라이트의 1904년 등이 높은 의자, 리트벨트의 1917년 적/청의자, 브로이어의 1925년 와실리 의자, 알토의 1932년 파이미오 의자, 이임즈의 1948년 DAR 의자, 피에로 가티의 1969년 사코 의자, 필립 스탁의 1984년 폰 포겔상 의자, 스텀프의 1992년 에어론 의자, 리틀의 1994년 코트 오브 암((oat of Arms)의자 등 - 의자디자인에서 자신의 이론을 표현할 기회를 가졌던 디자이너들의 리스트는 끝이 없어 보인다. 매킨토쉬(1868-1928), 라이트(1867-1959), 알토(1898-1976)와 같은 건축가들은 인테리어와 건축을 위한 예술적 계획속에 의자 디자인을 포함하였었다. 그러나 의자의 제조업자들이 장인의 영역에서 인더스트리얼 프로세스의 영역으로 이동됨에 따라, 디자이너들은 공학적 지식을 배경으로 현대적 제조 기술의 제한요소내에서 혁신적인 의자 디자인들을 개발하였다. 또한, 기능과 구조의 문제를 넘어서 의자의 기본적인 가치는 과거든 현재든 의자의 특성, 아이디어와 가치에 대한 전달에 있으며 의자에 대한 설득력은 그 수사학상의 명확성과 밀접한 관계가 있어 보인다. 의자는 디자이너들이 시각적으로 말하고 개인적 신념을 선언할 수 있는 이상적인 매체가 되어왔다. 미래에도 의자디자인은 비현실적 디자인과 실용적인 디자인 사이에서 계속 고민할 것이며 이것이 바로 디자이너들이 추구하는 유일한 길이라 하겠다.

The aim of this study is to improve the accuracy of field placement and junction between adjacent fields and block shielding through the use of a computed tomography(CT) simulator and virtual simulation. The information was acquired by assessment of Alderson Rando phantom image using CT simulator (I.Q. Xtra - Picker), determination of each field by virtual fluoroscopy of voxel IQ workstation AcQsim and colored critical structures that were obtained by contouring in virtual simulation. And also using a coronal, sagittal and axial view can determine the field and adjacent field gap correctly without calculation during the procedure. With the treatment planning by using the Helax TMS 4.0, the dose in the junction among the adjacent fields and the spinal cord and cribriform plate of the critical structure was evaluated by the dose volume histogram. The pilot image of coronal and sagittal view took about 2minutes and 26minutes to get 100 images. Image translation to the virtual simulation workstation took about 6minutes. Contouring a critical structure such as cribriform plate, spinal cord using a virtual fluoroscopy were eligible to determine a correct field and shielding. The process took about 20 minutes. As the result of the Helax planning, the dose distribution in adjacent field junction was ideal, and the dose level shows almost 100 percentage in the dose volume histogram of the spinal cord and cribriform plate CT simulation can get a correct therapy area due to enhancement of critical structures such as spinal cord and cribriform plate. In addition, using a Spiral CT scanner can be saved a lot of time to plan a simulation therefore this function can reduce difficulties to keep the patient position without any movements to the patient, physician and radiotherapy technician.

애니메이션은 작가의 의식을 표현하는 도구로서 공간과 공간을 통해 시간으로 전환하는 매체이다. 애니메이션의 구성요소에서 이미지는 가장 본질적 요소이며, 이미지 중 캐릭터는 가장 핵심적 기능을 가진 이미지요소이다. 왜냐하면 캐릭터는 다양한 동작과 표정을 통해 이야기를 전달하는 형상체이기 때문이다. 이러한 맥락에서 볼 때 <동물농장>은 조지오웰의 원작을 바탕으로 계급화 된 불평등의 인간사회와 여기에서 벌어지는 인간의 이기심과 부조리를 풍자적인 캐릭터를 중심으로 그려낸 대표적인 풍자애니메이션이다. 따라서 이번연구에서는 이 작품에서 설정된 인물과 동물들 그리고 공간이 지니고 있는 의미와 상징을 통해 무엇을 풍자했는지를 연구해 보고자하였다. 연구결과 작품에서 등장하는 캐릭터들은 단순한 인물이나 장소가 아니라 각각의 의미를 내포하고 있는 은유적 상징체임을 보여준다. 다시 말해 농장은 인간세상을 상징하는 공간으로써 인간인 존은 러시아 절대왕정의 민중을 억압하는 독재자로, 돼지인 올드 메이저는 혁명의 당위성을 설파하는 원로 선각자로, 메이저를 따르던 돼지 스노볼은 혁명을 성공시키고 만민이 평등한 참 사회주의를 건설하려는 순수한 지도자로, 또 다른 돼지인 나폴레옹은 개인적인 야욕을 위해 스노볼을 제거하고 동족인 동물들을 억압하고 착취하는 인간보다 더한 탐욕적인 독재자로 묘사하였다. 즉 인간과 다양한 동물들을 지배와 피지배의 계급관계로 설정하여 갈등을 양산하고 혁명을 통해 이상사회를 지향하지만 이는 또 다시 혁명을 예고하는 인간역사의 반복적 모순을 상징적이면서도 강렬하게 전달하고 있었다.

본 연구는 최근에 독도의 한일 간 영유권 논쟁이 심화된 것은 1953년부터 한국이 실효적 지배를 하는 독도에 대한 우리 정부의 영유권 행사와 강화에 직결된 독도개발정책 추진의 잘못에서도 그 원인이 있다고 보았다. 이러한 내부적 시각에서 1950년대 이후 2012년 7월 말까지의 정부의 독도개발정책을 성찰적으로 검토해 보고, 그간의 독도 개발정책과 우리 사회에서 제안된 상이한 개발방향에 대한 문제점의 논의를 바탕으로 미래의 바람직한 개발 대안을 모색하고 제안해 보고자 하였다. 역대 정부들은 거의 대부분 독도문제가 한일 간 선린외교관계의 형성과 유지에 걸림돌이 되는 것을 원치 않아 독도 영유권 강화에 필수적인 유인도 개발정책추진에 매우 소극적이었다. 오늘날 독도가 국제사회에서 한국의 독도(Dokdo island)로 인정받지 못하고, 대체로 리앙쿠르 암석(Liancourt rocks)으로 표기되고 있는 것은 우리 정부가 독도를 다수 한국인이 거주(정주)할 수 있는 가치 있는 유인도(island)로 적극적으로 개발하지 않았기 때문이기도 하다. 따라서 본 연구는 UN이 채택하고 있는 지속가능한 개발론 관점에서 독도의 미래 개발 대안으로서, 생태어업, 생태관광 및 동해 연구기능을 가진 소규모의 '독도 생태마을' 조성을 제안하였다. 독도 생태마을 안이 미래에 독도에 대한 우리의 영토주권과 실효적 지배를 강화하기 위한 새로운 독도개발정책의 논의와 수립에 실마리가 되었으면 한다.

The purpose of this study was to be of use for the preparation of more desirable sex education system at elementary school, by making content analysis of the current textbooks related to sex education and surveying what opinions the persons concerned had about it. The purpose of this study were as follows; Elementary school textbooks were analyzed to find out what kind of sex education was included in them. And questionnaires on how to improve school sex education content were prepared, by which 207 male and female teachers were surveyed in the city of Paju and Koyang, Kyonggi province. The conclusions were as follows; 1. Content Analysis of Textbook Sex Education The content related to sex education was relatively much included in textbooks of the right life, morality and physical education. Although morality was a subject to be instructed for the third-grade students or older, elementary school students virtually received sex education from the first grade, as the right life and the joyful life were a subject for the lower-grade students, and this met the goal of sex education or the need of the times. However, sex education content leaned heavily toward family, family life or parental love. There was no mutual complement among subjects, and no link among grades, either. 2. Teacher Opinion on Sex Education Content for Each Grade When the subjects were asked about if sex education content was appropriate for each grade, they answered 20 items should be more emphasized and 6 items might be left out. And there were 6 items regarded by them as one that should be rearranged in consideration of grade. 3. The Ideal Opinion of Sex Education Content The following model could be recommended for elementary school sex education, which was designed to meet the objectives of school sex education as much as possible and to offer a systematic link among grades, based on the findings by textbook analysis and Questionnaire survey, and on elementary school sex education materials recommended by the Ministry of Education: The content selected for the first grade of elementary school was my body, cleanness of genitals, male-female cooperation, and family cooperation. For the second grade, the selected content was male-female physical difference, male female psychological difference, parental and I(origin of a birth). For the third grade, the selected things were important a body(cleanness of genitals), birth of a life, and male-female comprehension and cooperation. For the fourth grade, the selected things were physical development, management of genitals, physiology and management of menstruation, propagation and growth of organism, concern for the other sex, comprehension of and cooperation with the other sex, and prevention of sexual violence. Four the fifth grade, the selected things were secondary sex characteristic, physiology and management of menstruation, operation for phimosis, understanding of seminal emission, structure and function of the genital organs, birth and growth of a baby, television/sex information, and mass communications/sex information. For the sixth grade, the selected things were secondary sex characteristic, understanding of seminal emission, male-female cooperation, male and female role, male-female manners, mass communications/sex information, family and family life. Finally, what should be taught in sex education must be studied constantly, as it should be revised or supplemented periodically, according to student's sexual maturity or social, cultural changes.

It is very important for the ideal restorations of anterior openbite patients to record the mandibular movement and to harmonize mandibular movement with other organs in stomatognathic systems. This study was designed to compare the mandibular movement of anterior openbite patients with that of normal bite(Angle Class I) patients, to ascertain which components of mandibular movement have differences between two groups, and to use for occlusal treatment of mandibular movement. Saphon Visi-trainer Model 3(Tokyo Shizaisha Co. Japan) and Denar Pantronic(Denar Corp.,U.S.A.) were used to record mandibular movement. Pantronic survey was peformed by using an arbitrary hinge axis according to manufacturer's direction. Twenty-eight adult who have physiologically normal occlusion(Angle Class I) and are free of TM dysfunction were selected as a control group(Group 1). Fifteen adult who are anterior openbite patient and have not anterior guidance function and have posterior interference at protrusion were selected as a experimental group(Group 2). The results are as follows : 1. There was no statistically significant difference between the average immediate and progressive side shift of anterior openbite patients(0.54mm, $7.57^{\circ}$) and those of normal group(0.49mm, $5.96^{\circ}$). 2. The average protrusive and orbiting condylar inclination of anterior openbite patient$(30.87^{\circ},\;32.27^{\circ})$ were significantly lower than those of normal group$(36.11^{\circ},\;39.04^{\circ})$ (P<0.05). 3. In the results of Visi-trainer recordings, the mean for the maximum protrusion, the maximum laterotrusion, the angle of laterotrusion and the angle of protrusion in the horizontal trajectory between group 1 and 2 did not differ significantly. 4. The mean for the angle of protrusion, the maximum opening in the frontal trajectory, the ICP-RCP(A-P) distance and the angle of protrusion in the sagittal trajectory differ significantly(P<0.05). 5. The significant correlation was found between orbiting condylar inclination and protrusive condylar inclination.

Three-dimensional porous scaffolds play an important role in tissue engineering strategies. They provide a void volume in which vascularization, new tissue formation, and remodeling can occur. Like any grafted materials, the ideal scaffold for bone tissue engineering should be biocompatible without causing an inflammatory response. It should also possess biodegradability, which provides a suitable three-dimensional environment for the cell function together with the capacity for gradual resorption and replacement by host bone tissue. Various scaffolds have already been developed for bone tissue engineering applications, including naturally derived materials, bioceramics, and synthetic polymers. The advantages of biodegradable synthetic polymers include the ability to tailor specific functions. The purpose of this study was to examine the osteogenic activity of periosteal-derived cells in a polydioxanone/pluronic F127 scaffold. Periosteal-derived cells were successfully differentiated into osteoblasts in the polydioxanone/pluronic F127 scaffold. ALP activity showed its peak level at 2 weeks of culture, followed by decreased activity during the culture period. Similar to biochemical data, the level of ALP mRNA in the periosteal-derived cells was also largely elevated at 2 weeks of culture. The level of osteocalcin mRNA was gradually increased during entire culture period. Calcium content was detactable at 1 week and increased in a time-dependent manner up to the entire duration of culture. Our results suggest that polydioxanone/pluronic F127 could be a suitable scaffold of periosteal-derived cells for bone tissue engineering.

The ideal goal of periodontal therapy is the regeneration of periodontal tissue repair of function. Although is very difficult to attain the goal, recent advances in periodontal wound healing concepts encourage hope reaching it. Recently many efforts are concentrated on the regeneration potential of material used in traditional Korean medicine. Phlomidis Radix has been used for the treatment of blood stasis, bone fracture and osteoporosis in traditional Korean medicine. The purpose of this study is to examine effects of dichloromethane fraction Phlomidis Radix on Bone Formation in Human Fetal Osteoblasts. Human fetal osteoblastic cell line(hFOB1 1.19 ;American Type Culture Collection, Manassas, VA) were used and cells were cultured containing DMEM and dichloromethane fraction Phlomidis Radix(100 ng/ml , 1 ${\mu}$/ml, 10 ${\mu}$/ml) at 34$^{\circ}C$ with 5% $CO_2$ in 100% humidity. MTT was performed to examine the viability of the cell, and alkaline phosphatase activity was analyzed to examine the mineralization. Also bone calcification nodules were evaluated. The cellular activity of hFOB1 was increased in 100 ng/ml, 1 ${\mu}$/ml , 10 ${\mu}$/ml of dichloromethane fraction of Phlomidis Radix and especially significant increation was showed in 100 ng/ml of dichloromethane fraction of Phlomidis Radix at 6days (p <0.05). ALP level of hFOB1 was significantly increased in 100 ng/ml , 1 ${\mu}$/ml, 10 ${\mu}$/ml of dichloromethane fraction of Phlomidis Radix and especially more increation was showed in 10 ${\mu}$/ml of dichloromethane fraction of Phlomidis Radix (p <0,05). Calcification nodules of hFOB1 significantly increased in 10 ${\mu]$/ml of dichloromethane fraction of Phlomidis Radix at 21 days of incubation(p<0.05). The results indicate that dicholoromethane fraction of Phlomidis Radix has excellent effects on mineralization of hFOB1.
