The purposes of this study were to arrange and analyze the Oriental Mode in 20th century fashion and to clarify that Oriental dress and its ornaments appearing as the main subject of Occident fashion gradually The results were as follows : First, Oriental Mode in 1900-1950s was prescribed as the 'Orientalism' to be expressed Occidental imperialistic viewpoint. Therefore, the Orient was used as the simple recording mark of the imperialism product or commercial motive and it was reflected in fashion. Second, it was explained in 1960-1970s as the 'Folklore Orientalism' that focus was moved into the folklore costume of Orient. Third, in 1980s, 'Ethnic' was conspicuous that reflected the traditional costume in the area of non-christianity. Especially, it was the decade that the Middle East attracted attention. Fourth, Oriental Mode in 1990s appeared as the 'Fusion' that Oriental and Occidental elements were mixed and compromised on equal terms. Fifth, it was expressed as a word 'Zen' that had natural fiber, moderate color and silhouette to be most basic and concise about human body at the end of 1990s. This study could confirm that the center of fashion was being converted into the Orient gradually. This may be understood as the pluralistic culture phenomenon. Namely, eclectic principle to recognize mutual style and individualistic nature and to utilize and mix was made, and this brought the conversion into Oriental sense of value.

In recent years, it Is necessary to develop an alternative measure, the time efficiency of management activities, as a more measurable and operational tool Instead of traditional accounting measures such as inventories turnover. Therefore the concept of throughput time has got much attention as useful tool for controlling time based management. The purpose of this paper is to investigate the usefulness and adaptability of throughput time. The sample consists of 212 non-banking firms listed on the Korean Stock Exchange. The test Period were 10 years(1989-1998). The regression analysis for this study was performed using the cross-sectional data for the sample, and it was also performed for each Industry. The results show that net Income to tonal assets and labor productivity (value added Per employee) variables in the model was signiflcantly associated with throughput time. On the other hand, the relationship between throughput time and logistics cost to sales do largely not have statistical significance. Especially, it is found that the relationship do not have significance or negative response in food & beverage industry and wholesale & retail industry. In summary, the results show that the measure of throughput time can be an effective managerial Indicator for time based competition and management.

This study examined the expression characteristics in pop art works of Jean-Charles de Castelbajac. The study here aimed at possibility to find a design development in building up the unique art world of creativity based on popularity, artistry, and originality without confinement to the trend only. For the research method, review of literature and analysis about Castelbajac's works reflecting the pop art feature in the collections from 2000S/S to 2012F/W were performed. The results of research are as follows. The external expression form of Castelbajac's works based on pop art was grouped roughly into use of mass culture image, appropriation of pop art expression technique, and parody of art works. First, his work appeared as application of the mass culture image such as symbolic thing in the modern consumer society, object in an ordinary life, character of well-known animation, national flag and famous star. Second, such appropriated pop art techniques showed as pop color in strong primary color and silk screen, photomontage, collage, assemblage, graffiti, and lettering. Third, a variety of images featured earlier in art works were shown in parody. These works are valuable in that they are expressed aesthetically through regeneration of popular culture's various images in view of fashion, they are described in the non-traditional value with frolic resistance and deviation out of existing fashion norm, and they are given the dynamic creativity integrated with art and fashion.

Numerous developments have damaged agricultural landscapes and consequently agricultural areas have lost the amenity and their traditional culture. Despite the fact that damaged agricultural landscape is irreversible, precautionary policies for conserving agricultural landscapes in Korea have not been established properly. Meanwhile, social demands for well preserved rural landscapes have increased. This study, thus, aims to evaluates esthetic values of agricultural landscapes in order to prepare the basis for the formulation of properly informed policies. Bearing in mind the purpose of the study, firstly, present status of agricultural landscapes has been surveyed. Secondly, agricultural landscape values were estimated in friendliness, ruralness, and preference with 30 selected slides and 4 computer simulated pictures out of 305 pictures. The survey has been carried out with two student's groups of the landscape architecture majored (50 people) and the ordinary majored (68). The results implicated that agricultural landscape preferences has not been changed for 10 years to some extent. However, landscape majored respondents showed low preferences on the artificial creatures than the non-majored. Lastly, Recommendations for the agricultural landscape policy was made that the necessary developments should be considers form, colour, location, and size according to the natural landscape.

This study examined the dyeing characteristics of five oriental herbs, namely Gardenia jasminoides, Sophora japonica L., Rheum coreanum, Rhus javanica L., Ginkgo biloba L., on fabrics with traditional fermentation using malt. And the properties of Hwangsu (mineral water) of Yeongcheon (Korea)as a mordant in the post-treatment of textile were evaluated. The dyeability and fastness of cotton fabric and silk to light and washing as well as different fermentation periods and temperatures were investigated, and the following results were obtained. The dyeability of the fermented and non-fermented material did not show a significant difference. Fabrics mordanted with Hwangsu generally exhibited a reddish color due to the presence of iron. The dyeing of cotton fabric and silk by fermentation and Hwangsu mordanting were found to be effective on Rhus javanica L. and Rheum coreanum. These results were confirmed through fastness to light 3 of cotton on Rheum coreanum and 3-4 of silk on Rhus javanica L., respectively. The washing fastness of both fabrics dyed with fermented Rhus javanica L. and Rheum coreanum was improved, showing higher K/S value after washing than before washing.

Phytochemical investigation on the ethyl acetate and n-butanol fractions of Moutan Cortex resulted in the isolation and characterization of a new monoterpene glycoside (3) and twenty known monoterpene glycosides (1, 2, 4-21). The structure of 3 was determined by spectroscopic data interpretation and physico-chemical properties. Compounds 1 and 8 presented a remarkable inhibitory activity against lipoxygenase-1 (LOX-1) with $IC_{50}$ values of 45.2 and $37.5\;{\mu}M$, respectively. Compounds 9, 10, 13, 18, 19, and 21 showed significant 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging effect with $IC_{50}$ values of 9.8, 25.5, 6.4, 15.2, 18.7, and $23.7\;{\mu}M$, respectively. Benzoylpaeoniflorin (8), which exhibited the highest inhibitory effect with an $IC_{50}$ value of $37.5{\pm}0.7{\mu}M$, was further analyzed the inhibition kinetics by Lineweaver-Burk plots. Results indicated that 8 is a non-competitive inhibitor, and the kinetic parameter values were estimated to be ($31.04\;{\mu}M$, Ki), ($0.29\;{\mu}M/min$, $V_m$), and ($48.50\;{\mu}M$, $K_m$).

As the environmental impacts of fossil fuel energy sources increase, the South Korean government has tried to change non-environmental-friendly enery sources to environmental-friendly energy sources in order to mitigate environmental effects, which lead to global warming and air pollution. With both a limited budget and limited time, it is essential to accurately evaluate the economic and environmental effects of renewable energy projects for the efficient and effective operation of renewable energy plants. Although the traditional economic evaluation methods are not ideal for evaluating the economic impacts of renewable energy projects, they can still be used for this purpose. Renewable energy projects involve many risks due to various uncertainties. For this reason, this study utilizes a real option method, the Geske compound model, to evaluate the renewable energy projects on Jeju Island in terms of economic and environmental values. This study has developed an economic evaluation model based on the Geske compound model to investigate the influences of flexibility and uncertainty factors on the evaluation process. This study further conducts a sensitivity analysis to examine how two uncertainty factors (namely, investment cost and wind energy production) influence the economic and environmental value of renewable energy projects.

The electrochemical reduction of carbon dioxide (CO₂) to value-added products is a remarkable approach for mitigating CO₂ emissions caused by the excessive consumption of fossil fuels. However, achieving the electrocatalytic reduction of CO₂ still faces some bottlenecks, including the large overpotential, undesirable selectivity, and slow electron transfer kinetics. Various electrocatalysts including metals, metals oxides, alloys, and single-atom catalysts have been widely researched to suppress HER performance, reduce overpotential and enhance the selectivity of CO₂RR over the last few decades. Among them, single-atom catalysts (SACs) have attracted a great deal of interest because of their advantages over traditional electrocatalysts such as maximized atomic utilization, tunable coordination environments and unique electronic structures. Herein, we discuss the mechanisms involved in the electroreduction of CO₂ to carbon monoxide (CO) and the fundamental concepts related to electrocatalysis. Then, we present an overview of recent advances in the design of high-performance noble and non-noble singleatom catalysts for the CO₂ reduction reaction.

영상은 어린이들의 호기심을 불러일으키고 많은 것을 접하게 하여 자연스러운 학습을 유도한다. 특히 애니메이션은 어린이들을 사회화시킴은 물론, 자아 정체성을 형성하는데 중요한 역할을 한다. 따라서 애니메이션 캐릭터의 젠더 정체성 재현은 중요하다. 애니메이션 캐릭터의 젠더 정체성의 재현 방식은 시각정보를 통한 재현방식과 내러티브를 통한 재현방식으로 나누어 볼 수 있으며, 내러티브를 통한 재현방식이 시각정보의 재현방식을 더욱 확고히 해줌을 알 수 있다. 또한 애니메이션 캐릭터의 젠더 정체성의 양상을 살펴보면, 보수적이고 상업적인 이데올로기를 투영하는 젠더 고정관념과 일치하는 캐릭터와 젠더 고정관념에서 탈피하고자하는 캐릭터로 구분되어 진다. 그러나 젠더 고정관념을 탈피하고자하는 캐릭터의 재현 역시 젠더 역할의 과장이나 희화를 통한 비판에 그치고 있다. 따라서 애니메이션 캐릭터들은, 여성이나 남성으로 구분되는 스테레오타입으로 재현되는 것이 아닌, 하나의 인간으로서의 가치를 주체적으로 형성해 가는, 미래지향적인 젠더 정체성을 가진 캐릭터들로 재현되어야 한다. 미래지향적인 젠더 정체성을 재현하는 애니메이션은 어린이들에게 올바른 자아 개념과 젠더 역할을 심어주며, 이미 획득된 전통적인 젠더 정체성을 완화시키는 역할을 수행한다.
