We investigated the miscibility of poly(methyl methacrylate) (PMMA) and random copolymers of tetrafluoroethylene-hexafluoropropylene-vinylidene fluoride (THV) blends and their interfacial adhesion as part of the development of cladding materials for PMMA based plastic optical fiber. Three different types of THV with different copolymer composition were used as candidates for them. PMMA/THV blends being melt-mixed at $240^{\circ}C$ showed typical immiscible morphology and the glass transition temperatures of the component polymers did not change after mixing. However, tie chains connecting matrix and dispersed phase were identified when THV with high content of vinylidene fluoride, i.e., THV220 was used. In spite of the intrinsic immiscibility of PMMA/THV blends the interfacial adhesion obtained from peel test was above $10^4N/m^2$ at the adhesion temperature of $240^{\circ}C$ and increased with increasing the temperature for THV220. From the melt viscosity data of the polymers it was recommended that the extrusion temperature of THV should be higher than that of PMMA in order to obtain smooth interface between core and cladding layer.

호스피스 완화의료에서의 초기평가와 돌봄 계획의 수립: 평가도구를 중심으로

박은주,고수진,천재경,Park, Eun Ju,Koh, Su Jin,Cheon, Jae Kyung 한국호스피스완화의료학회 2019 한국호스피스.완화의료학회지 Vol.22 No.2

포괄적이고 총체적 돌봄을 제공하는 호스피스 완화의료의 경우 평가도구를 사용하여 문제목록의 객관화하고 돌봄 계획의 구체화하는 것이 필요하다. 초기평가는 입원 당일 혹은 1일 이내에 환자의 증상과 사회적, 영적 문제, 완화의료에 대한 요구가 무엇인지 파악하며 개괄적인 돌봄의 방향을 설정하는 과정이다. 현재 병에 대한 인식과 예후를 파악하는 것부터 연명의료계획서 작성까지 함께 검토한다. 초기평가도구로는 간단하지만 포괄적으로 신체적, 정신적, 사회적, 영적 영역을 아우르는 13개의 간단한 질문으로 구성된 NEST를 추천한다. 초기평가에서 파악된 문제에 대하여 구체적인 평가도구들을 활용하여 돌봄 계획을 수립하며 입원 후 3일이내 시행하는 것이 좋다. 신체적 영역의 경우 기능상태를 포함하여 통증과 비 통증 증상, 삶의 질을 함께 파악할 수 있는 다증상 평가도구가 도움이 될 수 있다. 환자의 증상은 단독으로 의미를 가지는 것이 아니라 복합적인 상호작용으로 발생하며, 그에 따라 포괄적으로 접근해야 하기 때문이다. 정신심리적 영역은 심리적 고통과 불안, 우울을 평가한다. 사회적 영역의 평가는 의사결정, 사회경제적 환경 파악, 가족 평가 및 임종 준비의 단계로 이루어진다. 영적 평가 역시 중요한데 FACIT-Sp나 SHI를 사용할 수 있다. 평가도구를 활용하는 것은 환자의 고통을 경감시키고 삶의 질을 향상시킬 뿐 아니라 의료진이 체계적으로 훈련되는 방안이 될 수 있으며 그 과정 자체가 더 나은 돌봄 제공을 위한 발판이 될 수 있다. For hospice palliative care that provides comprehensive and general care, it is necessary to use assessment tools to objectively list issues and detail care plans. The initial assessment is a process of establishing an overall direction of care by identifying the patient's symptoms, social and spiritual issues and palliative care needs on the admission day or within one day of admission. This process is also used to identify the patients' and families' awareness of the illness, prognosis, treatment options and if the Physician Orders for Life-Sustaining Treatment (POLST) has been drafted. Consisting of 13 simple questions regarding the physical, mental, social, and spiritual domains, the Needs at the End-of-Life Screening Tool (NEST) is recommended as an initial assessment tool. Using specific assessment tools, a care plan is established for the issues identified in the initial assessment within three days of admission. A multidisciplinary assessment tool can be helpful in the physical domain. The psychosocial domain evaluates psychological distress, anxiety and depression. The social domain examines an ability to make decisions, understanding of the socioeconomic circumstance, family relationship, and death preparedness. A spiritual evaluation is also important, for which the Functional Assessment of Chronic Illness Therapy-Spiritual WellBeing Scale (FACIT-Sp) or the Spiritual Health Inventory (SHI) can be used. The use of an assessment tool could not only contribute to pain mitigation a better quality of life for patients, but also provide systematic training for a multidisciplinary team; And the process itself could be a stepping stone for the better care provision.

Effects of Cordyceps militaris Cultivated on Rice on Lipid Metabolism in Rats Fed High Fat-cholesterol Diets

박은주,Sang Mong Lee,Nam Sook Park 한국식품영양과학회 2006 Preventive Nutrition and Food Science Vol.11 No.2

Dongchunghacho rice, produced by cultivating Dongchunghacho fungus on rice, could be an effective functional food because it offers added value to rice and thus increases rice consumption. However, the physiological effect of Dongchunghacho rice has not been reported yet although there is increasing consumers demand. Therefore, we investigated the effect of Dongchunghacho rice (unpolished rice cultivated with Cordyceps militaris) on lipid metabolism in hyperlipidemic rats. Forty of 8 wk-old male Sprague-Dawley rats were divided into four groups after a 1 week of adaptation period and fed either a normal diet (66% polished rice diet, NC), high fat (12 g/100 g)-high cholesterol (1 g/100 g) diet with 53% polished rice (HC), or high fat-high cholesterol diets supplemented with 30% of the total rice as either unpolished rice (UR) or Dongchunghacho rice (DR). After 4 weeks, rats fed the Dongchunghacho rice diet with high fat and cholesterol had dramatically lower plasma LDL cholesterol concentrations and atherogenic indexes and higher plasma HDL cholesterol levels compared with the rats consuming polished rice or unpolished rice with high fat and cholesterol diet. Dongchunghacho rice led to less total lipid and total cholesterol accumulation in liver. However, these significant reductions in plasma or hepatic lipid profiles were not closely correlated with fecal total lipid or total cholesterol excretion. The plasma concentration of total cholesterol and triglycerides were not affected by Dongchunghacho rice. This hypolipidemic effect of Dongchunghacho rice seemed to be unrelated to unpolished rice itself, because the plasma and hepatic lipid profiles of UR group were not different from that of the HC group. These results suggest that unpolished rice containing cultivated Cordyceps militaris can improve plasma and hepatic lipid profiles in rats fed with high fat-high cholesterol diet.

The miscibility of the blends of polycarbonate (PC) and syndiotactic polystyrene (s-PS) was investigated by using differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). The blends exhibit two different glass transition temperatures ($T_g$) close to those of the pure components, indicating immiscibility at the melt mixing temperature of $280^{\circ}C$. Morphological studies of the blends shows large dispersed particles and significant cavities between the matrix and the dispersed phase, especially for the PC matrix blends. To reduce such detrimental effects, poly(methyl methacrylate) (PMMA) or styrene-maleic anhydride copolymer (SMA) was added as a compatibilizer to the PC/s-PS blends. Both polymers contribute to enhancing the interfacial adhesion between PC and s-PS and reduce the particle size of the dispersed phase. Especially when PMMA was added, morphological studies showed that PMMA encapsulates the dispersed s-PS phase in the PC matrix. The elastic modulus of the PC/s-PS blend increased on adding PMMA or SMA, mainly because of enhanced interfacial adhesion. The pencil hardness of PC increased at least three times from that of neat PC as a result of compatibilization and surface enrichment of the s-PS phase, whose surface tension is lower than that of PC.

ESCO사업에 민간자금이 투입될 예정이다. 산업자원부는 최근에 ESCO사업 활성화를 위한 중장기 발전방안을 발표했다. 이는 전주대 산업협력단이 수행한 'ESCO 사업 중장기 발전방안' 연구용역 결과를 토대로 한 것이다. ESCO사업은 지난 91년 사업 시작 이래 정책자금 9,130억원이 융자됐으며, 지난해 3,783억 원 가량의 에너지 절약효과를 거뒀다. 올해는 정책자금 수요가 2,410억 원에 이를 정도로 기업들의 관심도는 높아졌다. 그러나 정부의 예산은 1,474억 원 에 그쳐 돈이 절대적으로 부족한 형편이다. 이에 따라 최근 발표된 보고서는 민간자금을 유입시켜 정책자금의 부족을 해소하고 사업을 더욱 활성화하겠다는 내용이다. 연구 수행 책임을 맡은 전주대학교 기계자동차공학과 조성환 교수를 만나 이야기를 들어봤다.
