With increasing needs for affective design, it became an essential part in a product development process to look up quantitative ergonomic data that reflects customers' preferences on design factors in various products. This study looked at wide LCD monitors and analyzed customers' affective preferences regarding monitor's bezel frame size and shape. The monitor's bezel frame depth, size and ratio were selected as independent variables among many design parameters. As dependent variables, customer's subjective preferences were measured. A statistical analysis revealed that monitor's bezel frame depth, size and ratio had significant effects on customer's preferences. Also, it was possible to find a different tendency on affective variables and their levels for 19" and 24" wide LCD monitors. In general, experiments revealed that customers reacted more sensitively in 24" wide LCD monitors to all variables. In 19" wide LCD monitors, only the lower frame bezel size had a significant effect, otherwise, lower, upper and side frame bezels appeared to be effective variables in 24" monitors. In order to reflect customer's affective preferences to new design of wide LCD monitors, this study is expected to provide quantitative ergonomic data and guidelines for the design of wide LCD monitor's bezel frame depth and size.

Conventional rate control (RC) schemes for H.264 video coding usually regulate output bit rate to match channel bandwidth by adjusting quantization parameter (QP) at fixed full frame rate, and the passive frame skipping to avoid buffer overflow usually occurs when scene changes or high motions exist in video sequences especially at low bit rate, which degrades spatial-temporal quality and causes jerky effect. In this paper, an active content adaptive frame skipping scheme is proposed instead of passive methods, which skips subjectively trivial frames by structural similarity (SSIM) measurement between the original frame and the interpolated frame via motion vector (MV) copy scheme. The saved bits from skipped frames are allocated to coded key ones to enhance their spatial quality, and the skipped frames are well recovered based on MV copy scheme from adjacent key ones at the decoder side to maintain constant frame rate. Experimental results show that the proposed active SSIM-based frameskip scheme acquires better and more consistent spatial-temporal quality both in objective (PSNR) and subjective (SSIM) sense with low complexity compared to classic fixed frame rate control method JVT-G012 and prior objective metric based frameskip method.

This study aim to report 4 cases with chronic abdominal pain whose symptoms are alleviated by Sihogyeji-tanggagam with Korean medicine treatments. The patients were decided to administer Sihogyeji-tanggagam through abdominal examination. The patients were treated by Korean medicine, including acupuncture, moxibustion, and herbal medicine (Sihogyeji-tanggagam). We used Gastrointestinal Symptom Rating Scale (GSRS), Abdominal examination, Visual Analog Scale (VAS), and Subjective Unit of Clinical Symptoms to evaluate the progress of treatments. The improvement of clinical symptoms appeared to be effective with out any remarkable side effects. The abdominal pain of all patients stared to improve as soon as treatment begin, and disappeared in 1-2 weeks. We also confirmed that the abdominal symptoms improved together with the improvement of clinical symptoms. This study suggests that Sihogyeji-tanggagam is effective on reducing symptoms of chronic abdominal pain, but further studies should be followed.

Background: Conventional treatments for seborrheic dermatitis often lead to a recurring cycle of symptom improvement and worsening, resulting in chronic conditions. Thus, safer and more effective alternatives are needed. In Korean medicine, Hwangryunhaedok-tang tablets, targeted at treating the fire-heat syndrome, offer a more fundamental approach to manage seborrheic dermatitis. Clinical Features and Outcomes: In this study, we monitored the changes in the symptoms of two patients with seborrheic dermatitis who were treated with Hwangryunhaedoktang tablets. The patients were administered this medication during the treatment period. The effectiveness of the treatment was assessed by visually recording changes in the affected skin areas using photographs and evaluating symptoms such as heat, itching, and stinging in these areas using a visual analog scale (VAS). Visible improvements in the patients' skin conditions were observed after taking Hwangryunhaedok-tang tablets. Following treatment, VAS scores for subjective symptoms such as heat sensation, itching, and stinging in the affected areas decreased. Conclusion: This study offers evidence of a potential alternative approach for treating seborrheic dermatitis using Kyungbang Hwangryunhaedok-tang tablets. However, it highlights the necessity for further research on the appropriate dosage, side effects, and long-term effectiveness of this treatment.

기존의 부호화 기술은 부호화기의 복잡도가 복호화기에 비해 매우 높은 구조로 이루어져 있다. 하지만 최근에 부호화기 복잡도의 대부분을 차지했던 움직임 예측/보상과정을 없애는 경량화 부호화 구조에 대한 연구가 중요해졌다. Wyner-Ziv 부호화 기술은 이의 대표적인 기술로서 부호화기는 단순히 현재 프레임에 대한 패리티 정보만을 생성하며 프레임 간 유사성을 이용하는 어떠한 처리절차도 행하지 않기 때문에 종래의 기술에 비해 매우 간단한 구조를 갖는다. 하지만 Wyner-Ziv 부호화 구조에서는 잡음이 많은 보조영상을 복호화에 이용 할 경우 채널 코드의 복호화 오류가 발생한다. 이러한 복호화 오류는 특히 영상 간 유사성이 적어 보조정보를 잘 만들 수 없는 경우 더 많이 발생하며 복원된 영상에 마치 Salt & Pepper와 같은 형태의 잡음으로 나타난다. 이러한 잡음은 비록 그 발생빈도가 적더라도 복원된 영상의 주관적인 화질을 상당히 떨어뜨리는 요소로 작용하므로 이전에는 공간적 유사성을 이용하여 이러한 오류를 정정하는 선택적 미디언 필터를 사용한 경량화 부호화 방법을 제안하였었다. 하지만 이전 방법에서는 텍스처가 복잡한 영상의 경우, 필터적용에 따른 텍스처의 손실이 오류정정으로 얻는 이득보다 더 큰 경우가 발생하는 문제점이 있었다. 따라서 본 논문에서는 선택적 미디언 필터에 복원영상과 보조정보 내 잡음에 관한 정보를 제공함으로써 필터링에 따른 텍스처의 손실을 최소화하는 향상된 경량화 부호화 방법을 제안한다. 실험결과는 이전 방법에 비해 최대 0.84dB에 이르는 성능향상을 보였다.
