Even though rhythm is considered theoretically and practically as a form element influencing consumer's aesthetic response on product design, researches on it relatively less performed than other product aesthetic elements. And also existing researches have only suggested rhythm as one of aesthetic elements in product design but they haven't suggested overall insight on how to apply rhythm into product design. This study tested how rhythm expression in product design affects consumer's aesthetic response according to price level and brand hierarchy. The result shows that rhythm is clearly one of aesthetic elements. And rhythm expression increase consumer's aesthetic response in low priced product condition regardless of brand hierarchy. But in high priced product condition, rhythm expression decreases consumer's aesthetic response because of perceived risk. Only when in high prestige brand condition, consumer's aesthetic response remains high because of trade-off relationship between perceived risk and brand equity. The result of this study enables designers to understand characteristics of rhythm. Also, the result can give companies the useful way on how to use rhythm element as a strategic tool if they consider their brand equity level and product's price level.

The purpose of this study was to examine the changes of body composition and aging-related hormones by rhythmic exercise in elderly women. The subjects in this study were 20 olders living in a rural community, >60 years of age and were performed rhythmic exercise program during 12 weeks. The measurement of the body composition, body mass (t=3.125, p=.006), body mass index (t=3.225, p=0.004), body fat mass (t=3.782, p=0.001), waist-to-hip ratio (t=3.867, p=0.001) were significant difference after exercise program, but had no effect on lean body mass. Also, growth hormone (t=-2.221, p=0.039) and somatomedin-C (t=-9.186, p=0.000) were significantly increased after rhythmic exercise, however, rhythmic exercise had no effect on DHEA-S. These results suggest that rhythmic exercise appeared to effect of control on body composition and some aging-related hormones in elderly women.

배경: 승모판막 질환에 동반된 심방세동의 경우 그 기간이 길면 승모판막 질환을 수술하여도 동성 율동으로 전환될 가능성이 매우 적다. 본 연구는 승모판막 질환에 동반된 심방세동에 대한 변형 Maze 수술후 장기 결과와 심방세도의 재발에 미치는 요인을 조사 하고자 하였다. 대상 및 방법: 1990년부터 1996년까지 승모판막 질환과 동반된 심방세동으로 외과적 요법을 시행받은 35명의 환자를 대상으로 하였다. 심방세동의 평균 유병기간은 평균 7.7$\pm$4.5년이었고 수술은 승모판막 대치술 34례(재수술 3례)와 승모판막 성형술 1례를 시행하였고 승모판 질환 수술 외에 동반 수술로는 삼첨판륜 성형술 4례, 삼첨판막 대치술 3례 였다. 심 방세동에 대한 수술은 좌측 폐정맥 부위는 격리하지 않는 변형 Maze 수술을 시행하였다. 수술 후 동성 율동으로 회복여부, 심방세동의 재발에 미치는 요인과 장기 결과를 분석하였다. 결과: 수술 직후 2례를 제외한 33례(93.9%)에서 동성율동으로 돌아왔으나 수술 후 퇴원 전에 12례에서 심방세동이 재발되었다. 수술환자중 1례에서 수술 후 3일에 동성 정지에 따른 심정지가 발생하여 소생되었으나 뇌손상으로 수술 후 15일에 사망하였다. 심방세동이 재발된 경우 수술 후 약 2개월에서 6개월 사이에 항부정맥 약물(mquinidine)과 전기적 제세동으로 치료하여 12례중 10례에서 동성 율동으로 돌아온 환자는 항부정맥 약물을 모두 중단하 였으며, 수술 후 3년에서 9년(평균 71.1$\pm$17.5개월) 추적 관찰 중 9례에서 심방세동이 재발되어 장기간 동성 율동이 유지된 환자는 34명중 25명으로 73.5%이었다. 승모판 질환이 있던 환자에서 수술 후 심방세동의 재발에 미치는 요인들을 조사한 결과 수술전 심방세동의 기간(동성율동 유지군 : 재발군=6.3년 : 10.3년, P=0.008)과 수술 전 단순 흉부 X선상 심흉비율(0.58 : 0.72, p=0.009)은 통계학적으로 유의하게 나타났으나 심초음파 검사상 좌심방의 직경(57.2mm : 77.4mm, p=0.106)은 통계학적 유의성이 없었다. 결론: 심방세동이 있는 환자에서 동반 질환 수술시 병행하여 수술한다면 정상 동성 율동으로 회복될 기회를 증가시킬 수 있는 유용한 수술법으로 생각된다. 그러나 수술후 재발률을 감소시키기 위하여 적절한 술기의 변형에 대한 연구와 약물요법의 병행을 고려하여야 할 것으로 사료된다.

배경: Maze수술은 승모판 질환에 동반되는 심방세동의 효과적인 치료방법으로 알려져있다. 이 연구는 승모판 수술과 심방세동 수술을 동시에 시행한 환자에서 심방세동 수술 후 중기적인 결과와 그 재발 여부를 조사하였다. 대상 및 방법: 심방세동 수술과 승모판 수술을 받은 11예의 환자(10예는 류마티스성 승모판 질환)를 대상으로 하였다. Maze II 수술 및 그 변형수술을 6예에서 시행했고, Maze III 수술 및 그 변형수술을 5예에서 시행하였다. 심방세동 수술 후 좌심방의 수축정도를 심방세동 수술 없이 승모판 수술만으로 동율동을 얻은 경우와 비교하였다. 결과: Maze II 수술을 받은 환자 6예 중 5예(83.3%)에서, maze III 수술을 받은 환자 5예 모두에서 동율동을 회복하였다(전체적으로 90.9%). 전자의 1예(20%)와 후자의 2예(40%)에서 수술 후 각각 23, 2, 13개월만에 심방세동이 재발하였다. 그 후 다시 2예는 동율동으로 전환되었으나, 1예는 재발된 심방세동을 그대로 유지하고 있다. 변형술을 받은 3예에서는 심방세동의 재발이 없었다. Maze 수술 후 4예(40%)에서만 좌심방의 수축기능을 보였으며, maze 수술 후 좌심방 수축 정도(승모판의 A파의 속도)도 maze 수술 없이 승모판 수술과 항부정맥제 투여로 동율동을 회복한 경우보다 낮았다. 결론: 심방세동을 동반한 승모판 수술 환자에서 maze 수술로써 심방세동으로부터 동율동을 회복할 수 있으나 중기적으로 재발할 수 있으며, maze 수술 후 좌심방 수축정도는 상당히 떨어질 수 있다고 생각된다.

Recent works regarding video shot change detection algorithms show that abrupt shot changes are detected fairly well. However, gradual shot changes including wipes and dissolves are often missed or falsely detected. A robust shot change detection system, therefore, must include a shot verification step to further enhance the overall system performance. In this paper, we introduce the concept of the visual rhythm which is a single image, a subsampled version of a full video. On the visual rhythm, the different video edit effects such as cuts, wipes and dissolves manifest themselves as different patterns. Using this characteristic, it becomes possible, without sequentially playing the entire video, to find false positive shots as well as undetected shots. Thus, inclusion of the visual rhythm in the shot boundary verification process will aid the operator to exclude falsely detected shots as well as to find undetected shots fast and efficiently. For this purpose we have developed a new tool, a shot verifier incorporating the visual rhythm. The usefulness of the visual rhythm during the shot verification process will be presented.

Atrial fibrillation is the most common of all cardiac arrhythmias. It is associated with significant morbidity and mortality and is frequently resistant to medical therapy. On the experimental and clinical study, the presence of macroreentrant circuits and the absence of either microreentrant circuits or evidence of atrial automaticity suggests that atrial fibrillation should be amenable to surgical ablation. The results of the maze III procedure are associated with a higher incidence of postoperative sinus rhythm, improved long-term sinus node function, fewer pacemaker requirements, less arrhythmia recurrence, and improved long-term atrial transport function. We had experienced 4 patients with chronic atrial fibrillation. For the first time, Hioki procedure had been performed in the first patient with ASD and atrial fibrillation, regular sinus rhythm showed on postoperative EKG, but junctional rhythm and bradycardia developed postoperative 3 years. The maze III procedure for the rest with mitral valvular disease and atrial fibrillation had been done, followed by regular sinus rhythm for 2 patients and atrial fibrillation for 1 patient, managed with amiodarone, on immediate postoperative state. Echocardiogram documented good contraction of right atrium and hardly contraction of left atrium for 2 patients with regular sinus rhythm postoperative 3 months.

대부분의 디자인관련 종사자들은 심미성이 소비자의 선호에 중요한 영향을 미친다는 주장에 동의하고 있다. 하지만 어떠한 심미적 요소가 소비자 선호도에 얼마큼 영향을 미치는지에 대한 연구가 미미한 편이다. 따라서 본 연구는 심미적 영향 요소인 율동에 관한 사례연구를 통하여 구체적 영향 정도를 파악하고 연구결과를 이용 소비자 선호도를 높일 수 있는 방안 제시를 시도할 것이다.

The purpose of this study was to determine the effects of rhythmic movement therapy for adaptation state in mastectomy patients. The quasi-experimental study was designed using nonequivalent control group pretest-posttest design within the framework of Laszarus & Folkman's stress-adaptation model. The subjects of the study were composed thirty-two mastectomy patients, of these fifteen were assigned to the experimental group and seventeen to the control group. Rhythmic movement therapy was carried out twice a week for thirty-five, minutes or forty minutes for six weeks period from August 22 to September 30 in 1994. Data was collected before and after the experimentation. Collected data was analyzed by mens of chi-square test, t-test, two-way ANOVA, Pearson's correlation coefficient with $SPSS/PC^+$. The results were summarized as follows : 1. Physical symptom score in the experimental group and control group was not significant difference. 2. Joint Movement Parameter in the experimental group and control group was significant difference. 3. Depression score in the experimental group and contrl group was significant difference. 4. Body image score in the experimental group and control group was significant difference. 5. Stress perception score in the experimental group and control group was significant difference. 6. Social adjustment score in the experimental group and control group was significant difference. 7. Each adaptational level in the experimental group and control group according to type of Health Locus of Control were partially significant difference. Depression score and social adjustment score between the experimental group and control group according to others Health Locus of control were significant difference. This data suggest that rhythmic movement therapy was more effective in the group of Others health Locus of Control. 8. Each adaptational level between the experimental group and control group according to amount of spouse support were not significant difference. 9. The significant positive correlation between physical symptom score and body image, between body image and social adjustment, were observed. The significant negative correlation between stress perception score and social adjustment, between depression and body image, between depression and social adjustment, were observed. This data suggest that the more physical symptom score increased, the more body image increased and the more body image, the more social adjustment. And then the more stress perception score decreased, the more social adjustment increasded and the more depression score, the more body image and social adjustment. Thus it is concluded that the rhythmic movement therapy was a useful nursing intervention for adaptation of mastectomy patients.

Among the factors of consumer preference, aesthetics has been importantly considered in competitive market environment. Generally, consumers' purchasing standard is influenced as their awareness increases relative to variations in their lifestyles and due to these changes in consumers' wishes, design techniques and methods are focused towards adapting to these changes. Thus, in order to satisfy consumers' needs, and markets characterized with the short durability cycle of products, a distinctive design should be developed with respect to the form of products. The proposed design should also support form as an important factor to attract consumers preference. This study attempts to understand typology based on a categorization theory, and the conceptual structure of aesthetics. Both are importantly considered simultaneously. In addition, the study proposes a new design process by extracting Rhythm affecting aesthetic. In conclusion, the result of this study aims at developing more consumer preferring design beyond the scope of the ordinary designer's idea and generation.
