This study examined the wearing effect of 3D compression suits on quantitative electroencephalogram (EEG) during walking and rest. Ten males in their 20s wore three types of experimental clothing, a loose-fit wear (BS), a 3D compression suit (3D CS), and a power film welded on CS (3D WCS); in addition, EEG signals were measured during resting, walking, after walking, and after sit-ups. The results showed that a higher pressure (due to 3D CS and 3D WCS) increased the 'Concentration' level and the 'Cognitive load' of brain waves during treadmill walking due to a higher cortex activity level when walking. Differentiation was shown between two compression suits and BS was enhanced during walking on a treadmill; however, the brain waves of 'Relaxation' between two compression suits were significantly different after walking, i.e., 'Relaxation' level of 3D WCS was the highest. Rigorous exercise such as sit-ups was inefficient to distinguish the effect of compression suits on EEG. Participants perceived a higher pressure due to compression suits; however, the wear comfort of two compression suits was maintained. Two compression suits were rated as supportive and helpful during walking. Various EEG parameters such as the indices of 'Relaxation', 'Concentration' and 'Cognitive load' were effective to observe the effect of 3D compression suits on wearers' brain waves during and after walking.

Objective: The purpose of this study was to investigate how different levels of compression exerted on the femoral region (known as the power zone) by coated fabric influences the activation and anaerobic capacity of the rectus femoris. Method: Three different levels of compression on the rectus femoris of the participants, namely 0% (normal condition), 9% (downsize), and 18% (downsize), were tested. The material of the fabric used in this study was nonfunctional polyurethane. Surface electromyography test was used to investigate the activation of the rectus femoris, while the isokinetic test (Cybex, $60^{\circ}/sec$) and Wingate test were used to investigate the maximum anaerobic power. Results: The different compression levels (0%, 9%, and 18%) did not improve the strength and anaerobic capacity of the knee extensor. However, knee flexor interfered with activation of the biceps femoris, which is an agonist for flexion, during 18% compression. Conclusion: Compression garments might improve the stretch shortening cycle effect at the time of eccentric contraction and during transition from eccentric to concentric contraction. Therefore, future studies are required to further investigate these findings.

This study analyzed the fabric and product size of the burn patient's custom compression garment and measured the pressure applied by the garment to assess whether proper pressure is being delivered for treatment. The test clothes were presented to the market by body size and commissioned with the same design. The subjects selected four people close to the average body size of men in their 20s determined by 7th Size Korea. The experiment was conducted by wearing a compression suit, performing activities and measuring changes in the pressure of the garment according to changes in posture. The fabric used for the compressive clothing was not ruptured even at 216 kPa, the elasticity recovery rate was measured between 80.5 and 94.5%. The product dimensions of the experimental clothing varied by up to 8cm from brand to brand, requiring the standardization of compression clothing. The experiment showed that four types of compression suit varied in pressure, and the pressure range, excluding the gastric arm (17.9mmHg), was between 2.5-14.1mmHg, which failed to meet the level of pressurization for treatment purposes. The clothing pressure in the chest area dropped when performing movements rather than standing still. This was interpreted to be a result of reduced the adhesion of the compression suit during operation. The peak pressure (31.68mmHg) and the lowest pressure (2.2mmHg) was noted in the scapula, indicating that no pressure was being transmitted on the vertebrae. The pressure of the garment on the right shoulder blade was elevated in a supine position. Because much time is spent laying down, it is necessary for the pattern design to accommodate for the increased clothing pressure on the shoulder blades. Standardization of the level of pressurization for burn patient's custom-made pressure suits for each stage of treatment is urgently required.

본 연구는 남성 수트소재의 구성적 특성과 역학적 특성이 남성 수트소재의 시각적 질감 이미지와 선호도에 미치는 영향을 분석하는 것이다. 시판하는 남성용 검정색 계열의 춘하 소재 20종을 수집하여, 시각적 질감 이미지에 대한 주관적인 평가를 실시하였고, 피험자는 의류학과 대학원생과 의류관련 업체 종사하는 $20\~30$대 전문가 여성으로 구성하였다. 요인분석으로 "부피감", "신축감$\cdot$드레이프성", "강연감", "평활감"의 요인이 추출되었으며, "강연성"과 굽힘특성과의 관계를 제외한 역학적 특성 평가와 시각적 질감 이미지 평가가 일치하였다. 선호도에 가장 영향을 주는 것은 "평활감", 압축에너지(WC), 밀도, "강연성"이었으며, 시각적으로 매끄럽고 부드럽고 압축에 필요한 에너지가 적고 밀도가 성근 직물을 춘하 남성용 정장으로 선호하였다.

This research investigated the influences of structural characteristics such as fabrics, mechanical properties, and subjective sensory images on the off-line and on-line preferences to women's spring/summer suits fabrics to extract the most effective factor towards preference as well as analyze the preferential off-line and on-line differences to predict the exact texture image on-line. Objective evaluations were done for the measurement of the mechanical properties of fabrics using Kawabata's Evaluation System and subjective evaluations were done with 109 female subjects who value the off-line and on-line sensory image of suit fabrics. For statistical analysis, factor analysis, cluster analysis, t-test, ANOVA, and regression were used. The results were as follows. The preference scores on-line were generally higher than those off-line. For the structural characteristics of fabrics, differences of thickness were observed according to preference clusters, and the preference increased as thickness was lowered off-line and on-line. For mechanical properties, WC influenced off-line and on-line preferences. Fabrics with low compression energy were preferred; however, the effect of SMD was observed off-line only. In subjective sensory images, the 'smoothness' image influenced off-line and on-line preferences the most. All sensory images influenced the off-line preferences; however, the effects of 'flexibility' and 'weight' were not shown on-line.

환자가 죽음에 임박했을 때 환자, 보호자, 의사 사이에서 심폐소생술에 대한 논의는 피할 수 없는 주제이다. 환자가 회복 불가능한 말기의 암환자인 경우에는 환자의 품위 있는 죽음을 고려하여 심폐소생술을 시행하지 않음(Do-not-resuscitate, DNR)을 결정하게 된다. 그러나 DNR에 대한 선택은 환자와 보호자의 심폐소생술과 DNR의 의미 및 그 결과에 대한 이해를 바탕으로 한다. DNR에 대하여 환자, 보호자, 의료진이 상담을 할 때는 환자의 질환이 더 이상 치료가 불가능하며, 심폐소생술이 환자의 생명을 연장시키는 것이 아니라 죽음의 과정을 연장시키는 것이며, 심폐소생술 이후에 삶의 질이 급격히 나빠질 수 있는 상황이라는 합의가 필요하다. 충분한 이해는 환자 또는 보호자가 품위 있는 죽음을 위한 DNR을 선택하도록 한다. 국내에서는 DNR 자체 보다는 이미 생명유지장치를 가지고 있는 환자에서의 생명유지장치의 제거에 대한 법적인 문제가 2차례 발생하면서 사회적으로 품위 있는 죽음에 대한 일반 대중의 관심이 이전보다 증가하였다. 환자와 의료진을 대상으로 한 설문에서는 DNR에 대한 인식과 의지가 80년대에 비해 2000년대 초반에 이르러 상당히 증가하였으나, 실제 의료 현장에서는 DNR의 결정에 있어 환자가 직접 관여를 하는 경우는 많지 않았고 DNR 작성 시점과 사망 시점과의 시간 간격이 1주 이내로 환자가 관여를 하거나 임종시기의 의료를 결정하기에는 너무 짧은 문제가 있었다. 이러한 문제는 조기 완화의료의 확산을 통하여 개선이 가능할 것으로 생각된다. 일부에서는 DNR이라는 용어보다는 자연적인 죽음을 허용함(Allow-Natural-Death)이라는 용어로 바꾸어서 설명하는 것이 이해를 돕고 선택의 갈등을 줄인다는 보고를 하여 DNR 논의와 결정에 있어서 적절한 시기 이외에도 환자와 보호자에게 많은 어려움이 있다는 것을 보여 주고 있다. DNR은 말기암환자에서 품위 있는 죽음을 위해 고려해야 하는 사항이며, 임상에서 DNR이 잘 시행되도록 임상적, 제도적 노력이 필요하다.
