It has been general view to Josun palace space that the Kyongbok palace, a main palace, is arranged with symmetric geometrical composition principles and, unlikely main palace, sub-palaces such as Changduk, Changkyong and Kyonghee palace are placed in organic structure adapted to natural land form. With that view, there are no common factors to be considered between these palace, main and sub palace, in composting principles of the space. In this study, because of same ideological period, although there is external difference of that palaces, that common ideological principles are projected to these two palaces types through compositing space is assumed. On this hypostasis, this study has been focused on finding the ideological principles projected to these palace space commonly. As result of study, some of them are considered as common principles; Firstly, they are arranged in the text of contents through the way of naming to building, enterence and so on. The second point is ; it is viewed that the Oheung and symmetric arrangement method based on Oheung are used in compositing of palace space. The third is ; through analizing central space of Kyongbok palace, it is analized that oneness composition principles, which are based on the theory of Umyangheong, are projected to different palace space commonly.

Endometriosis is a common gynecologic disease, worldwide, whose true prevalence is uncertain because it is a difficult disease to diagnose. Endometriosis is a common cause of chronic pelvic pain, dysmenorrhea, and infertility, and is also associated with ovarian cancer. Although the risk factors for endometriosis are unclear, there is increasing evidence that exposure to environmental contaminants, especially phthalates, could affect the pathogenesis of endometriosis. Phthalates are industrial chemicals, used to make flexible plastics, and are present in numerous common plastic products, including medical devices and materials. Several in vitro studies have suggested a positive association between exposure to phthalate, or phthalate metabolites, and the risk of endometriosis. Since the 2000s, studies based on human plasma and urinary concentrations of various phthalate metabolites have been published, but there are still limitations to our understanding of the pathophysiology of phthalates and endometriosis. This report aims to review the current state of knowledge about a possible role of phthalates in the pathogenesis of endometriosis based on cell culture, animal models, and human data.

The denim fashion is a style of clothing showing trends towards globalization in that it is most favored and most frequently purchased and worn by youngsters throughout the world. However, it differs from region to region in its shapes, colors, silhouettes and coordination, reflecting a feature of regionalism. Male denim fashion data were collected from large cities of the East and the West for an analysis in terms of design and coordination. It was found that a common point originated from the features of the clothing itself as well as from a common culture shared among those of similar ages while differences came from various factors such as aesthetic sentiments and lifestyle of each ethnic group, willingness to accept the fashion trends, and the ways of expressing oneself by means of clothing and their attitude towards clothing. It was noteworthy that the denim fashion in Europe and America, Beijing and Seoul differed largely owing to their different tastes for expressing themselves. A comparison study of the regional denim styles may lead to a better understanding of a worldwide phenomenon of the common fashion trends and regional differences in aesthetic appeal and the fashion preference.

Significant changes in the past year have taken place in the world of work that are bringing new challenges with regard to employee safety and health. These changes have led to emerging psychosocial risks (PSRs) at work. The risks are primarily linked to how work is designed, organized, and managed, and to the economic and social frame of work. These factors have increased the level of work-related stress and can lead to serious deterioration in mental and physical health. In tackling PSRs, the European labor inspectorates can have an important role by enforcing preventive and/or corrective interventions in the content and context of work. However, to improve working conditions, unilateral interventions in the context and content of work are insufficient and require adopting a common strategy to tackle PSRs, based on a holistic approach. The implementation of a common strategy by the European Labor Inspectorate for tackling PSRs is restricted by the lack of a common legislative frame with regard to PSR evaluation and management, the different levels of labor inspectors' training, and the different levels of employees' and employers' health and safety culture.

This paper presents two advanced hybrid pulse-width modulation (PWM) strategies for multilevel inverters (MLIs) that provide both common-mode voltage (CMV) elimination and current ripple reduction. The first PWM utilizes sequences that apply one switching state at the double ends of a half-carrier cycle. The second PWM combines the advantages of the former and an existing four-state PWM. Analyses of the harmonic characteristics of the two groups of switching sequences based on a general switching voltage model are carried out, and algorithms to optimize the current ripple are proposed. These methods are simple and can be implemented online for general n-level inverters. Using a three-level NPC inverter and a five-level CHB inverter, good performances in terms of the root mean square current ripple are obtained with the proposed PWM schemes as indicated through improved harmonic distortion factors when compared to existing schemes in almost the entire region of the modulation index. This also leads to a significant reduction in the current total harmonic distortion. Simulation and experimental results are provided to verify the effectiveness of the proposed PWM methods.

In this study, experiments and numerical analysis were conducted to investigate the exhaust gas flow in a common exhaust system of multiple solid oxide fuel cells. The system was fabricated based on KGS code and operated within a pressure range of 0.12 kPa, with flow rates ranging from 79.1 to 103.4 L/min. Numerical modeling was validated with a mean absolute error of 3.8% for pressure results. The study assessed the impact of changes in area ratio and emergency stops on pressure distribution, velocity vectors, and wall shear stress. The findings revealed no significant factors causing high differential pressure or backflow.

Postponing childbirth is becoming increasingly common and consequently serious social problem in Korea, among married-working women. It is relatively unknown which factors determine married-working women's childbirth intention. This study investigated the effects of demographical factors, labor market factors and social support factors on married-working women's childbirth intention. Data from a national survey of married-working women (Korean longitudinal survey of women and families) are used in this study. The findings are as follows. First, logistic regression analyses that married-working women's childbirth intention could be predicted by 1) personal characteristic factors such as age (p <.000), education level (p<.029), parenthood (p<.000) monthly pay (p<.01); 2) husband support factors, such as satisfaction with division of household labor (p<.009), time with family (p<.049) influence of family life on work (p<.083); and 3) institutional support factors such as regular position (p<.015), regression analysis showed similar results. Personal characteristic factors and husband support factors had statistically significant effects on the number of future children. Personal value factors such as traditional family support (p<.05) proved to be the best predictor of the number of future children. Institutional support factors, on the other hand, did not have statistically significant effect on the number of future children. In a nutshell, personal characteristics and husband support proved to be the most important determinant of married-working women's childbirth intention. The findings suggest that family friendly policy and flexible labor market policy will impact married-working women's childbirth intention.

本文研究共同特性对于无选择权的影响, 并涉及到了调节焦点理论. 本文主要着眼于这三个因子以及他们之间的关系. 之前的研究已经广泛涉及到这三个方面. 第一, 共同特性影响已经被广为研究. Tversky (1972) 开创了这个理论, EBA 模型: 通过消除方面. 根据这个理论, 消费者在比较的过程中更易于注意特殊的特性, 而忽略共同特性. 最近, 更多的研究开始针对于此模型对于消费者行为的影响. Chernev (1997) 认为增加共同特性可以减少选择距离. 但是, 随后Chernev (2001) 的研究指出共同特性可能是消费者认知上的负担, 所以他们更喜欢启发式的过程而不是系统式的过程. 这些研究提出了一系列问题: 共同特性是否影响顾客选择? 如果是的话, 这些影响是什么样子的? 第二, 一些研究指出没有选择的状况是消费者最好的选择, 他们在犹豫不决时用这种方法回避选择. 其他关于这一理论的研究是时间的压力, 消费者自信, 以及可供选择的数量. 第三, 调节聚焦理论在目前非常流行. 消费者有两个焦点目标: 促进和制止. 促进聚焦主要和希望, 野心, 成功, 获得等有关; 而制止聚焦和责任, 职责, 安全, 规避等有关. 调节聚焦理论预测了顾客的感情, 创造, 态度, 记忆, 表现, 和判断. 而这些都是市场营销研究的领域这些文献为本文的研究提供了一些理论支持. 特别是增加共同特征而不是忽略他们可以增加选择过程中克制消费者的没有选择状况的比重, 其对于促进消费者的作用确实相反的. 本文通过两个试验进行验证. 第一个是2 X 2 组间的设计(共同特性X调节聚焦), 数码相机作为相关的客体. 特别的是, 调节聚焦变量是从11个问题中取得的. 共同特性包括焦距, 重量, 记忆卡, 电池, 而像素和价格作为独特特性. 结果证明了我们的假设, 那就是增加共同特性增加了克制消费者的无选择比重, 而对促进消费者没有作用. 第二个试验被用来复制第一个实验的结果. 这个实验和之前的基本相同, 只有两个方面不同—主要控制和研究客体. 在促进的前提下, 研究对象必须一些词例如: 利润, 野心, 高兴, 成功, 发展等. 在克制的前提下, 他们必学写下坚持, 安全, 保护, 规避, 损失, 责任等词. 实验证明我们假设是成立的. 本研究说明了共同特性对于顾客选择的二重效果. 增加共同特性可以提高或者降低无选择状况. 本文对于理论研究和实践上都有着贡献. 对于市场营销人员来说, 他们可能需要根据顾客的划分来考虑产品的共同特性. 理论上, 研究结果支持共同特性和无选择状况的调节变量. 最后, 本文也有一些不足, 例如过于强调态度的重要性等. 我们希望本文能够为未来的研究做出抛砖引玉的作用.

Cooperation between the GVWS within a few hundred meters has forced MWRs equipped to have service ranges in such a short ranges as well as the limited numbers of channels are available. This kind of situation often produces the frequency interferences between MWRs due to the easy uses of the common and adjacent frequencies between them. Current work provides the details of the frequency interferences and the possible degrees of detections. It is also described that the effective distances for the operation between the GVWS are investigated when they use the common and the adjacent frequencies each other with the factors as the frequency intervals and the antenna arrangement angles.

The following research focused on developing a new concept of lighting design with design factors which considered combining common natural objects with feelings. The purpose of this research is to write a thesis that deals with the whole process of developing a design for 'FEELighting' that is applicable to daily life through developing a form of lighting, which prioritizes feelings rather than materials, forms, or functions, and enhance the quality of people's lives. In particular, the process has been materialized by defining a new concept of 'FEELighting' (Feeling + Lighting), researching and analyzing the original and unfamiliar correlation between feeling and lighting, and choosing the embedded acrylics lighting items that can undergo small quantity batch production. As a result, prototypes of various forms of lightings that could be applied to daily lives -ceiling lights, wall light lamps, and table lamps-, which were made by combining numerous common natural objects and surpassed simple function and created to surpass simple lighting function, were presented through every process of design development.
