  • The aim of this thesis is to investigate the change of men and women's costumes in late 18th century and early 19th century in view of its ideological streams by examining the portraits of the painter Jacques-Louis David. The method of investigation used was to select 29 pieces of portraits from 1766 to 1825, which showed the clear descriptions about the costumes and to analyze the costume's forms, ornaments and the headdress. The category was divided into 3 stages in terms of the changes in costume. The first stage, from 1766 until 1788, is the one of turnaround from the Rococo costume to the early neoclassical one. The typical Rococo costume was incrementally transformed into a simpler design without ornaments, and then natural silhouette in men and women's costumes started to appear from 1783 until 1788. This might be attributed to the neoclassical trend which was affected by the enlightenment ideology. The second stage, from 1788 until 1795, is the period of change from the costume of the early neoclassic style to the typical neoclassic style and also the time from the 1793 to 1795 was regarded as the peak of neoclassic style when the effect of enlightenment began to decrease while one of neoclassicism exerted its strong influence on the costume. The third stage, from 1795 until 1825, similar to the previous neoclassical style was also notable in its turning into producing the empire dress of Empire style. From 1820 on, it was a period that showed signs of influence from romanticism while the effect of neoclassicism started to become more diminished.

  • Early 20th century Singapore was faced with the problem of overcrowding. The attendant problems of a rapid increase in population density, namely the lack of proper housing and sanitation, resulted in the issue of an appropriate residential environment emerging as an important task in urban planning. It was necessary to construct housing estates in order to solve this issue. At that time, the British colonial government attempted to transplant modern technology into the construction process of a residential complex system. However, Singapore's climate and traditional lifestyle made it impossible to apply the British modern system in a straightforward manner, and in the process, a number of transformations emerged. With a specific focus on the Tiong Bahru estate, one of Singapore's representative public housing projects, from the 1930s through the 1950s, this study intends to look at the way in which such residential estates were assimilated into local surroundings, and the effect of the transplantation of British concepts of modern housing theory. Therefore, the study is divided into an examination of the estate both before and after the turning point of World War II. This study confirms that the difference between the pre-war and post-war planning strategies for the Tiong Bahru estate were made according to the concept of 'open space.'

  • To see if the treatments of d-amphetamine and chlorpromazine have any influence upon the orienting response and general behavioral activity, 3 groups of male Holtzman rats were prepared, namely d-amphetamine animals (1.0 mg/kg.i.p.), chlorpromazine rats (1.0 mg/kg.i.p.) and the physiological saline control animals. The general behavioral activity was examined by visual scanning using the time-sample method in the adaptation period of orienting response. The occurence of orienting response and its rate of habituation were evaluated by observing cessation of ongoing activity in response to a sound stimulus (1,000 Hz, 70 db & 0.1 sec), or turning of head toward the source of stimulus in 20 trials. Attention shift from sound to light stimulus was also tested in 10 trials. The results obtained were as follows; 1. The general behavioral activity of d-amphetamine group was significantly greater than that of control, however, the chlorpromazine animals showed the tendency to decrease in activity. 2. The d-amphetamine group showed the occurence of orienting response to sound significantly more often than that of placebo controls. However, the chlorpromazine group exhibited significantly fewer orienting response than the placebo group did. 3. The d-amphetamine group displayed no clear out habituation to the orienting response following the repetition of trials, though the placebo and the chlorpromazine groups demonstrated apparent habituation to the response. 4. The three animal groups did not differ significantly from each other with regard to shift of attention from sound to light stimulus. It is inferred that the d-amphetamine tends to increase general activity has a definite facilitative action of orienting response and a inhibitory influence upon the habituation of the latter response. On the contrary, the chlorpromazine tends to decrease general activity, has a inhibitory action of orienting response and facilitatory action of habituation of the response.

  • The air-flow dyeing machine is a new type of dyeing machine. Which is an energy saving type to be able to dye the fabrics with the lowest liquor ratio and in shorter time. This machine is operated with an aerodynamic system rather than a hyd raulic system for traditional jet or overflow dyeing. An air-flow dyeing machine(Green-flow) by the use of aerodynamic technology was developed and compared with the Luft-roto machine made by Thies Company, Germany, in this study. Three samples were dyed with both machines under the same dyeing conditions and color fastness, dyeing levelness, drapability, and mechanical properties of these samples were compared. The results were as follows; Both machines have almost the same dyeability. The dyeability was good at liquor ratio of 1: 3.5 and the speed of 450yds/min. The order for drapability was Crepe de Chine > Cool Peach > Charmeuse. Except for the color fastness of sublimation being below class 4, most color fastness of samples dyed with Green-flow m/c were above class 4. The maximum speed was 510yds/min. for Crepe de Chine and the standard deviation of K/S value was lower for Charmeuse and Cool Peach when employed on the "Green-flow" machine and lower for Crepe de Chine when employed on the Luft-roto machine. Comparing with dyeing of the Green-flow machine and that of the Luft-roto machine, the RT of the Charmeuse was found to be higher with the Green-flow machine and thus the sample had an improved wrinkle recovery. LT and WT of Cool Peach were higher, and shear properties(G, 2HG, 2HGS) of Crepe de Chine were higher, both turning out as suitable for clothing. clothing.

  • 에너지는 경제활동과 사람들의 삶에 있어서 필수적인 요소이고 다양한 산업에서 활용하고 있는 중요한 자원이며 상품 시장의 금융화로 인해 원유가 다른 자산과 동일한 자산으로 변함으로써 그 중요성이 커지고 있다. 이에 따라 에너지 가격과 투자 심리간의 상관관계를 분석한 연구들은 대부분 경제적 요인과 투기를 통해 투자 심리가 유가에 영향을 미친다고 설명하고 있다. 본 연구에서는 에너지 가격과 관련하여 가장 대표적인 유가 변동에 따른 충격이 투자자 의사결정에 영향을 미쳐 투자 심리 변화에 영항을 주는가에 대한 내용을 중심으로 전반적인 에너지 가격 변동이 투자 심리에 영향을 미치는가에 대한 내용을 분석하고자 하였으며, 에너지 가격이 투자 심리에 어떠한 연관성이 있는지를 파악하기 위하여 웨이블릿 일관성 분석(wavelet coherence analysis)을 적용하여 주기별(단기, 중기, 장기) 에너지 가격이 투자 심리를 예측할 수 있는지를 분석하였다. 연구결과 에너지 가격과 투자 심리 사이의 시간 척도별로 차이가 발생하며 투자 심리 안정화를 위해 정책은 시간 척도별 효과를 고려하여야 하며, 에너지 가격과 관련한 투자 심리의 영향력은 단기보다 장기에서 더 크게 나타나고 있으며 마지막으로 시장에 영향을 미칠 수 있는 특정 사건 등이 발생하는 경우 에너지 가격과 투자 심리의 관련성 차이가 발생하기 때문에 이를 감안한 정책 및 시장 변화에 집중해야 할 필요가 있는 것으로 판단된다.

  • Purpose: The purpose of this study is to investigate the effects of older adult's head-turn gait on gait parameters by comparing with head oriented forward gait and to provide criteria for their risk of falling compared to young adult. Methods: The subjects were 19 young adults in their 20s and 18 older adults in their 60s or above residing in Daegu or Gyeongsangbuk-do. To evaluate their gait parameters, spatiotemporal gait parameters were measured using a gait analysis tool (Legsys, BioSensics, USA) under two conditions: 1) walking while keeping one's eyes forward and 2) walking while turning the head. The measurement for each test was performed after one practice session, and the mean value of three measurements was analyzed. The collected data were statistically processed using a two-way analysis of variance (ANOVA) to compare any differences in gait parameters between the two groups under the two conditions. The statistical significance level was set at α=0.05. Results: According to the comparison of gait parameters in young adult and older adult between the head oriented forward gait and head-turn gait, statistically significant differences were observed in two parameters: stride length according to the height ratio and stride speed obtained by dividing the stride length according to the height ratio by time (p<0.05). Conclusion: The results of this study indicate that the head-turn gait causes greater differences in stride length and speed among older adult than in young adult and therefore can act as a cause of falling.

  • Environmental Impact Assessment (EIA) is a kind of planning technique to seek ways to minimize environmental impact, a scheme to encourage sustainable development. With the launch of the Ministry of Environment in 1980, the EIA was introduced in Korea. Its full operation was initially driven by regulations on documenting EIA reports in 1981, which was piloted as a decision-making scheme where final decision were made at the development department after considering opinions suggested by the Ministry of Environment. At that time, dominance of the economic logic overwhelmed environ-friendly opinions, but thanks to the fourth revision of the Environmental Conservation Law in 1986, private projects came to be included on the EIA list. This was a turning point for the EIA to become a regulatory system. Local governments are also conducting the EIA regardless of the national-level EIA. In order to prevent and resolve increasingly severe environmental problems in Seoul in advance due to various construction projects, the Seoul Metropolitan Government, for the first time as a local government in Korea, legislated city decrees to introduce the EIA which has been underway from September 1, 2002. In particular, the Seoul government, unlike the Ministry of Environment, has included construction works on the list of evaluation projects, adopting the scoping and screen procedure scheme. In addition, complementing operational setbacks, the city government has revised and implemented decrees and enforcement laws on the Impact Assessment on Environment, Transportation and Disasters by shortening the consultation period, eliminating the submission of reports on construction, and expanding the waiver requirements in consultation over the reports. Therefore, development measures for the EIA scheme of the Seoul Metropolitan Government will be the target of the research. To that end, the up-to-date data of the Ministry of Environment, the Seoul government and local governments was collected, and latest materials from the EU, previous research and the Internet were gathered for analyses. By doing so, the flow of the EIA was reviewed, and the EIA schemes of local governments under the national EIA were analyzed. Furthermore, based on the Seoul government's recent data on the EIA based on the decrees, the background and legislation of the Seoul government's EIA were analyzed along with the developments for the environmental organizations. Setbacks were derived from the implementation period, evaluation procedures, consultation period and details of the EIA, and corresponding development measures were proposed.

  • 도시의 급변하는 교통수요에 대응하기 위해서 지속적으로 교통시설을 공급하는 데에는 한계가 있으므로 맹목적인 시설공급보다는 현재 교통시설에서의 운영관리측면이 강조되고있다. 특히 신호교차로들로 이루어진 단속류에서는 연동을 고려한 각 교차로별 최적신호시간 부여가 중요하다. 그러나 방향별로 부여된 신호시간이 단속류의 통과용량에 주요 변수인 것을 감안할 때 첨두시와 같이 교통수요가 급증하는 상황에서 보호좌회전 신호를 포함하는 4현시 신호운영을 지속적으로 유지하는 것은 방향별 통과용량에서의 한계가 있으며, 이에 대응하여 기존 과포화 신호제어 방법으로 내부미터링 기법에 대한 연구도 그동안 진행되어왔으나 실시간 신호제어시스템 상의 대기행렬 검지기 설치 부재로 인해 적용되지 못하고 있는 실정이다. 본 연구에서는 도시 간선도로의 지정체를 완화하기 위한 새로운 방법으로 현재 삼성역 교차로에서 운영 중에 있는 제한적 좌회전 신호운영 방안을 간선가로축을 대상으로 적용하였다. 이것은 시간대에 따라 주방향에 대한 좌회전 흐름을 직진 후 U턴으로 유도하여 현시수를 감소시키고 직진 신호시간을 최대화하여 통과용량을 증가시키는 신호제어 방법을 적용하는 것이다. 단, 본 신호제어에 대한 적용은 대상구간의 기하구조와 교통상황 조건 등에 따라 결정되어져야 하며, 이를 위해 기존의 교통 신호등 설치기준과 같이 각 교통상황 조건별로 명확한 적용기준이 필요하다.
