Emotion in motion: A Study on representation of sculpture and body form by the theme of human emotion in motion

This thesis explores the relationship between human emotion and physical expression. The ultimate objective is to communicate essential aspects of the human condition in order to improve understanding and appreciation of our common attributes. In this way, this study is intended to establish artistic identity of the human being through imaginative expressions. In the introduction, essential aspects of specific human emotions and the corresponding physical expressions will be identified. For my initial research, I studied the work of various inspiring artists in their portrayal of human emotions. I attempted to identify the expressions and techniques they used to communicate human emotions clearly through their art. Next I classified the work according to subjects, effects, and types. I examined the materials and techniques used in order to find the balance between materials, artistic styles, and forms and to gather ideas for originality. Finally, I considered possibilities for composition making optimal use of space and material to construct the functional and aesthetic parts. Maintaining a focus on my main concept was helpful in achieving a pleasing unification of the functional and aesthetic aspects of each piece. Through creative expression, this study will benefit not only making works but also regaining the identity of human consciousness by the resourceful arts and culture. Based on the initial conception, expression of human motion will be exposed to the mind and emotion of humans through philosophical and conceptual observations. Our common human identity can be revealed and communicated through the process to realize this vision. I hope this project needs to make the utmost use of our experimental expression

Is the Role of Work Engagement Essential to Employee Performance or ‘Nice to Have’?

The current study aimed to scrutinize roles of work engagement as a mediator in the relationships between job and personal resources and employees’ outcomes, namely job performance and turnover intention, specifically focusing on testing the essentiality of work engagement. A total of 571 complete responses from full-time employees in Korean organizations were utilized for data analysis with structural equation modeling (SEM). This study analyzed two research models through the competing model approach: One model (Model 1) specified that job and personal resources directly influence job performance and turnover intention and also indirectly influence job performance and turnover intention through work engagement, whereas the other model (Model 2) specified that job and personal resources only indirectly influence turnover intention and job performance through work engagement. The results of the competing models demonstrated that overall, Model 2 adequately fit better than Model 1. The results also showed that the direct effects of job and personal resources on work engagement, as well as the direct effects of work engagement on job performance and turnover intention were statistically significant. In addition, the results of the study revealed statistically significant mediating effects of work engagement, not only on the relationship between job and personal resources and job performance, but also on the relationship between job and personal resources and turnover intention. Based on the results, theoretical and practical implications for human resource management, limitations, and recommendations for further research are discussed

A Tilted Dark Halo Origin of the Galactic Disk Warp and Flare

The outer disk of the Milky Way Galaxy is warped and flared. Several mechanisms have been proposed to explain these phenomena, but none have quantitatively reproduced both features. Recent work has demonstrated that the Galactic stellar halo is tilted with respect to the disk plane, suggesting that at least some component of the dark matter halo may also be tilted. Here we show that a dark halo tilted in the same direction as the stellar halo can induce a warp and flare in the Galactic disk at the same amplitude and orientation as the data. In our model the warp is visible in both the gas and stars of all ages, which is consistent with the breadth of observational tracers of the warp. These results, in combination with data in the stellar halo, provide compelling evidence that our Galaxy is embedded in a tilted dark matter halo. This misalignment of the dark halo and the disk holds clue to the formation history of the Galaxy, and represents the next step in the dynamical modeling of the Galactic potential.Comment: Published in Nature Astronomy 14 September 202

Match me if you can: Semantic Correspondence Learning with Unpaired Images

Recent approaches for semantic correspondence have focused on obtaining high-quality correspondences using a complicated network, refining the ambiguous or noisy matching points. Despite their performance improvements, they remain constrained by the limited training pairs due to costly point-level annotations. This paper proposes a simple yet effective method that performs training with unlabeled pairs to complement both limited image pairs and sparse point pairs, requiring neither extra labeled keypoints nor trainable modules. We fundamentally extend the data quantity and variety by augmenting new unannotated pairs not primitively provided as training pairs in benchmarks. Using a simple teacher-student framework, we offer reliable pseudo correspondences to the student network via machine supervision. Finally, the performance of our network is steadily improved by the proposed iterative training, putting back the student as a teacher to generate refined labels and train a new student repeatedly. Our models outperform the milestone baselines, including state-of-the-art methods on semantic correspondence benchmarks.Comment: 12 page

InFusionSurf: Refining Neural RGB-D Surface Reconstruction Using Per-Frame Intrinsic Refinement and TSDF Fusion Prior Learning

We introduce InFusionSurf, a novel approach to enhance the fidelity of neural radiance field (NeRF) frameworks for 3D surface reconstruction using RGB-D video frames. Building upon previous methods that have employed feature encoding to improve optimization speed, we further improve the reconstruction quality with minimal impact on optimization time by refining depth information. Our per-frame intrinsic refinement scheme addresses frame-specific blurs caused by camera motion in each depth frame. Furthermore, InFusionSurf utilizes a classical real-time 3D surface reconstruction method, the truncated signed distance field (TSDF) Fusion, as prior knowledge to pretrain the feature grid to support reconstruction details while accelerating the training. The quantitative and qualitative experiments comparing the performances of InFusionSurf against prior work indicate that our method is capable of accurately reconstructing a scene without sacrificing optimization speed. We also demonstrate the effectiveness of our per-frame intrinsic refinement and TSDF Fusion prior learning techniques via an ablation study

Historical review of Samsung's innovations and further steps

Thesis (S.M.)--Massachusetts Institute of Technology, Sloan School of Management, 2011.Cataloged from PDF version of thesis.Includes bibliographical references (p. 82).Samsung Group has been growing rapidly for the last ten years, based on Korean exclusive historical and economic backgrounds. Especially, Samsung Electronics, the biggest subsidiaries in the Samsung Group has grown very fast in that period with the technological background - the features of the digital era and disruptive technology and the other background - Korean domestic situation also makes Samsung Group grow so fast. In the most adverse economic environment the Korean government supported Samsung Group entirely and their "Frankfurt Announcement" in 1993 was meant to get over Asian Financial Crisis in 1997. Their distinctive factors to be successful are their structures, the triangle structure and the vertically integrated structure among the subsidiaries. The triangle structure stands for the ownership, future strategy office, and the professional CEOs of subsidiaries and it provides the fast decision making process and the vertically integrated structure helps Samsung Group finding the new opportunity. I review their history and the backgrounds which influenced on them and diagnose their internal successful factors with the specific cases, and try to find out their factors by comparing them with LG Electronics, the domestic competitor which went through the same historical and economic situation and with Sony which used to the insurmountable top company to Samsung Electronics and currently becomes the big competitor.by Jiwon Han.S.M

Rapid Dye Regeneration Mechanism of Dye-Sensitized Solar Cells

During the light-harvesting process of dye-sensitized solar cells (DSSCs), the hole localized on the dye after the charge separation yields an oxidized dye, D^+. The fast regeneration of D^+ using the redox pair (typically the I^–/I_(3)^– couple) is critical for the efficient DSSCs. However, the kinetic processes of dye regeneration remain uncertain, still promoting vigorous debates. Here, we use molecular dynamics simulations to determine that the inner-sphere electron-transfer pathway provides a rapid dye regeneration route of ∼4 ps, where penetration of I^− next to D^+ enables an immediate electron transfer, forming a kinetic barrier. This explains the recently reported ultrafast dye regeneration rate of a few picoseconds determined experimentally. We expect that our MD based comprehensive understanding of the dye regeneration mechanism will provide a helpful guideline in designing TiO_2−dye−electrolyte interfacial systems for better performing DSSCs

Expression and Distribution Pattern of Retinoic Acid Receptors in the Nasal Mucosa

Background and Objectives Retinoids are naturally occurring vitamin A derivatives that regulate cellular processes and metabolism. In particular, retinoids play a key role in cellular proliferation by binding to retinoic acid receptors (RAR)-alpha, beta, and gamma. Considering the functional role of nasal mucosa where active cell regeneration occurs, RAR may play a role in tissue remodeling of the human nasal mucosa. Methods In this study, we investigated the expression and distribution pattern of RAR using reverse transcription-polymerase chain reaction (RT-PCR), immunohistochemistry (IHC) and Western blot in normal ethmoid mucosa (NE), chronic rhinosinusitis (IE) and polyp (P). Results IE and P samples showed higher expression levels of RAR in RT-PCR and Western blot than NE samples. RAR reactivity was also observed in the NE group, which indicates that cell regeneration also occurs in normal condition. Through IHC, we found the localization of RAR. RAR-α was distributed in the epithelial cells, submucosal glands, and endothelial cells. RAR-β was located in the basal epithelium, while RAR-γ was present in goblet cells and submucosal glands. The staining intensity of RAR-α, β and γ was higher than that in the NE group. Especially in the P group, RARs were abundantly distributed in the stalks of polyps. Conclusion The stalk region contains a lot of collagen and fibroblasts to support polyp formation, and the greater amount of RAR in the stalk suggested that RARs may be associated with angiogenesis and cell proliferation. Accordingly, elevated RAR levels in chronic rhinosinusitis could indicate that RARs play a critical role in cell regeneration, angiogenesis and immunomodulation under inflammatory conditions in the human nasal mucosa
