서론: 작업치료 관점에서 살펴본 노인의상디자인의 접근을 알아보고 노인 작업치료의 기초자료로 제공하고자 한다. 본론: 작업치료 관점에서 노인의상디자인을 접근하고자 작업치료와 옷입기, 노인과 옷입기, 노인의 이미지 메이킹, 노화에 대한 의상디자인으로 나누었다. 작업치료 수행영역 중 일상생활 활동의 옷입기는 여러 단계로 나뉘며 노인분들에게 도움이 필요하여 보조도구와 교육을 제공할 수 있다. 노화에 대한의상디자인에서 노인의 편의성을 위해 입기 쉬운 디자인, 기능적 패턴, 조절의 용이성 등이 고려되어야 한다. 결론: 노인 의상에서도 상황과 목적에 맞게 의상을 착용하면 노인의 일상생활활동에 도움이 되며 작업치료 관점에서도 노인 의상에 대한 많은 관심이 필요하다. Introduction : The purpose of this study is to know the approach of senior fashion design discussed in the occupational therapy perspectives and provide the material of occupational therapy for seniors.

A hepatic hemangioma is the most frequent benign liver tumor. Once rupture occurs, the bleeding can barely be controlled by using conservative management or endovascular treatment. We report a case of traumatic hepatic hemangioma rupture. A 60-year-old man was referred to our hospital under cardiopulmonary cerebral resuscitation (CPCR). CPCR was continued for 16 minutes after his admission to the emergency room (ER). Computed tomography (CT) showed fluid accumulation in the peritoneal cavity with active contrast extravasation in the left lateral segment of the liver. Percutaneous transarterial embolization and massive transfusion were carried out. Embolization did not stop the bleeding, we decided on an exploration and then resected the lateral segment of the liver to control the bleeding. The specimen showed a ruptured hemangioma in the liver segment

The aim of this study is to find out the level of satisfaction of professional hairdressers and consumers after flat iron hair service, and to analyze consumers’ intention of repurchase and recommendation of said service. The method is to divide the two groups-professional hairdressers and consumers, and analyzing frequency, and doing trustworthy and reason analysis to know the satisfaction level after service. Also, a multiple regression analysis was taken to find out the relationship between professionals’ satisfaction or consumers’ satisfaction when doing the service and consumers’ willingness to re-purchase afterwards. Firstly, common traits of professionals’ group subjects were with 3 to 5 years of experience and those with 10 or more years of experience. In the consumers’ group, subjects were mostly woman, in their 30s and 40s. Second, the level of professionals’ satisfaction on their flat iron service was reasoned out by the value of the service, frequency, training, the work environment, selling products, effect on the service, and condition of the hair. And consumers’ satisfaction on their flat iron service was based on the reasonability of the service, outcome, quality of the service, frequency, and purchase of the products. Third, in professional group, ‘Training’ was the factor of high satisfaction on flat iron service. Fourth, in consumers’ group, the intention of repurchase was dependent upon purchasing products, friendliness of the hair salon was dependent upon the result of the service, and intention of recommendation was depending on fairness on the price of the service and products. Finally, intention of continuous visits was affected by fairness of the price, and purchase of the product was the main factor of intention on re-visits regardless of services provided by other hair salons.

맥문동(Liriope platyphylla)은 염증(inflammation), 당뇨(diabetes), 신경퇴행성질환(neurodegenerative disorder), 비만(obesity), 변비(constipation), 아토피질환(atopic dermatitis) 등의 다양한 임상질환에 매우 우수한 치료효과를 나타내는 것으로 알려져왔다. 또한, 하이드로콜로이드막(hydrocolloid membranes, HCM)은 피부경화증 피부궤양(scleroderma skin ulcers), 피부궤양(cutaneous ulcers), 영구적 고막천공(permanent tympanic membrane perforations), 욕창(pressure sores), 욕창궤양(decubitus ulcers)과 같은 피부질환 치료에 많이 사용되고 있다. 따라서 본 연구에서는 기능성이 우수한 맥문동 추출물을 HCM에 혼합하여 맥문동 혼합 하이드로콜로이드막(HCM-LP)을 제조하고, 물리화학적 특성을 분석한 뒤 2도 화상을 유발한 SD 랫드에 14일 동안 처리하여 치료효과를 분석하였다. 그 결과, 일반 하이드로콜로이드막(HCM)에 비하여 HCM-LP에서 인장강도와 흡수성은 각각 38.4%, 46.3% 감소하였으나 표면거칠기는 38.1% 증가하였다. 화상을 유발한 SD 랫드에서 HCM-LP를 처리한 결과, 화상 유발 14일 후에 HCM-LP처리그룹은 GZ처리그룹에 비하여 유의적으로 화상크기 감소를 나타내었을 뿐만 아니라 흉터감소, 재상피화, 신생혈관형성 그리고 세포외기질의 침적을 유도하였다. 따라서 이러한 결과는 HCM-LP가 신생혈관형성과 연결조직형성 조절을 통해 SD 랫드에서의 화상 치료를 향상시킴을 의미한다. 또한, 본 연구는 HCM-LP가 피부상처의 치료에 적용할 수 있는 다른 기능성 물질을 포함하는 HCM의 개발에 대한 가능성을 제시하고 있다. A variety of previous pharmacological studies have suggested Liriope platyphylla (L. platyphylla) may exert beneficial biological effects on inflammation, diabetes, neurodegenerative disorder, obesity, constipation, and atopic dermatitis. In addition, hydrocolloid membranes (HCMs) have attracted attention in dermatological care, including in the treatment of scleroderma skin ulcers, cutaneous ulcers, permanent tympanic membrane perforations, pressure sores, and decubitus ulcers in the elderly. To investigate the therapeutic effects of HCM containing an aqueous extract of L. platyphylla (HCM-LP) on second-degree burn wounds, their physico-chemical properties were analyzed and the therapeutic effects were observed in SD rats after treatment with HCM-LP for 14 days. Significant declines in tensile strength (38.4%) and absorptiveness (46.3%), as well as an increase in surface roughness (38.1%) were detected in HCM-LP compared with that of HCM. In SD rats with burned skin, the wound diameter was shorter in the CM-LP treated group than in the GZ group on post-surgical day 14, while the significant improvements in scar tissue reduction, epithelium regeneration, angiogenesis, and extracellular matrix deposition were observed in the HCM-LP-treated group during all experimental periods. Overall, these results suggest HCM-LP may accelerate the process of healing the burn injury skin of SD rats through the regulation of angiogenesis and connective tissue formation.

Epigallocatechin gallate (EGCG)는 녹차(Camellia sinensis, green tea)에 포함되어 있는 대표적인 카테킨(Catechin)으로, 당뇨(diabetes), 신경퇴행성 질환(neurodegenerative disorders), 암(cancer), 심혈관계 질환(cardiovascular disease), 비만(obesity) 등의 다양한 임상질환에 우수한 치료효과를 나타내는 것으로 알려왔다. 본 연구에서는 EGCG가 LPS (Lipopolysaccaride)로 자극된 RAW264.7 세포의 염증억제과정에서 Nitric oxide (NO)관련인자와 사이토카인 발현에 미치는 영향을 분석하기 위해, NO농도, inducible NO synthase (iNOS) 발현량, TNF-α, IL-1β, IL-6, IL-10 사이토카인의 발현량을 분석하였다. 먼저, EGCG (100-400 μM)를 처리한 Raw264.7 세포에서 특이적인 독성이 나타나지 않음을 확인하였으며, 이후 Raw264.7 세포에 4가지 다른 농도(0.1, 0.5, 1.0, 5.0 ㎍/ml)의 LPS를 처리한 후 MTT분석, NO농도분석, IL-6농도분석을 실시하여, 염증을 유발할 수 있는 최적 LPS 농도를 1 ㎍/ml로 설정하였다. NO농도를 분석한 결과, LPS를 처리한 그룹이 No그룹에 비하여 급속히 증가하여 63 μ㏖/l까지 증가하였으나 400 μM EGCG를 처리한 그룹에서만 68.2% 정도 감소하였으며, 동시에 iNOS 발현 양상은 200, 400 μM EGCG/LPS 처리 그룹에서 각각 12.3%, 17.4% 감소하였다. 또한, 감소비율에는 차이가 있었으나, anti-inflammatory 사이토카인(IL-1β, TNF-α)과 pro-inflammatory 사이토카인(IL-10)의 발현은 EGCG/LPS 처리에 따라 유의적으로 감소하였다. 그러나, IL-6단백질과 mRNA 농도는 Vehicle/LPS 처리 그룹과 EGCG/LPS 처리 그룹에서 유의적인 차이를 나타내지 않았다. 따라서, 본 연구의 결과는 EGCG가 LPS의 자극에 의해 활성화된 Raw264.7 세포를 효과적으로 억제하는 효능을 나타냄을 제시하고 있으며, 이러한 과정에 사이토카인들이 서로 다르게 특이적 반응을 중계함을 제시하고 있다. Epigallocatechin gallate (EGCG), the main catechin in green tea, has been shown to have some beneficial effects against various human diseases, including diabetes, neurodegenerative disorders, cancer, cardiovascular disease and obesity. To investigate the mechanism of the suppressive effects of EGCG on inflammatory response in macrophages, alterations on the levels of nitric oxide (NO) regulatory factors and inflammatory cytokines were measured in lipopolysaccharide (LPS)-activated RAW264.7 cells. No significant toxicity was detected in RAW264.7 cells treated with 100?400 μM EGCG. Moreover, the optimal concentration of LPS was determined to be 1 ㎍/ml based on the results of cell viability assay, NO assay and IL-6 enzyme-linked immunsorbent assay (ELISA). Furthermore, NO levels decreased significantly by 68.2% in the 400 μM EGCG/LPS treated group, while the level of inducible nitric oxide synthase (iNOS) expression decreased by 12-17% in the 200 and 400 μM EGCG/LPS treated group. A significant decrease in transcription of pro-inflammatory cytokines (TNF-α and IL-1β) and anti-inflammatory cytokine (IL-10) was also detected in the EGCG/LPS treated group. However, IL-6 transcript and protein was maintained at a constant level when in the LPS treated group relative to the EGCG/LPS treated group. Overall, these results suggest that the differential regulation of inflammatory cytokines is an important factor influencing the suppressive effects of EGCG against LPS-activated inflammatory response in RAW264.7 cells.
