최근 유리산업은 에너지 절감효과와 친환경 재료의 사용을 바탕으로 하여 기존 유리의 특성을 변화시켜 보다 양질의 재료를 생산해 내고자 한다. 또한 인위적으로 가시광선 전파장에 대한 투과율을 조절할 수 있는 유리 제작의 필요성이 대두되어 스마트 윈도우(smart window)라는 신소재유리가 주목받고 있다. 스마트 윈도우는 태양광의 투과율을 자유롭게 조절할 수 있는 물질을 윈도우에 삽입함으로써 필름을 장착하는 방식에 비하여 태양광의 투과율이 대폭 신장됨과 동시에 사용자에게 고도의 편의성을 제공하는 장점이 있다. 액정과 고분자 매트릭스를 혼합한 PDLC용액을 이용하여 $3{\times}4cm^2$ 크기의 스마트 윈도우를 제작하여 유리 두께, 광량, 스페이서 크기에 따른 투과율을 측정하였다.

Objectives : The purpose of this study is to investigate the clinical application of Tong shun-san to three patients with compression fracture. Methods : Three patients were hospitalized at Dept. of Oriental Rehabilitation, Bu-Chun Jaseng Oriental Medicine Hospital, diagnosed as compression fracture and treated mainly with herbal medicine ; Tong shun-san. Their conditions were measured by VAS(Visual Analogue Scale) score. Results : After taking Tong shun-san, their pain was reduced. And VAS score was decreased. Conclusions : During three patients with compression fracture were taking Tong shun-san, their conditions were improved.

Objectives: The purpose of this case is to investigate and report the effectiveness of korean Medicine treatment and Harpagophytum radix. Pharmacopuncture for the type 1 complex regional pain syndrome. Methods: One patient is admitted at Bu-Chun Jaseng Hospital of Korean Medicine, diagnosed as type 1 complex regional pain syndrome and treated with korean Medicine treatment and Harpagophytum radix. pharmacopuncture. This case is measured and assessed by Neumerical Rating Scale(NRS), Oswestry Low-back Pain Disability Index(ODI) and Manual Muscle Test(MMT). Results: After treatment, the intensity and frequency of complex regional pain is gradually decreased and the result of NRS, ODI, MMT showed improvement. Conclusions: As seen in this cases of type 1 complex regional pain syndrome, korean Medicine treatment and Harpagophytum radix. pharmacopuncture appear to be effective for the pain relief and musculoskeletal function recovery.

Evaluating cell metabolism is crucial during pluripotent stem cell (PSC) differentiation and somatic cell reprogramming as it affects cell fate. As cultured stem cells are heterogeneous, a comparative analysis of relative metabolism using existing metabolic analysis methods is difficult, resulting in inaccuracies. In this study, we measured human PSC basal metabolic levels using a Seahorse analyzer. We used fibroblasts, human induced PSCs, and human embryonic stem cells to monitor changes in basal metabolic levels according to cell number and determine the number of cells suitable for analysis. We evaluated normalization methods using glucose and selected the most suitable for the metabolic analysis of heterogeneous PSCs during the reprogramming stage. The response of fibroblasts to glucose increased with starvation time, with oxygen consumption rate and extracellular acidification rate responding most effectively to glucose 4 hours after starvation and declining after 5 hours of starvation. Fibroblasts and PSCs achieved appropriate responses to glucose without damaging their metabolism 2~4 and 2~3 hours after starvation, respectively. We developed a novel method for comparing basal metabolic rates of fibroblasts and PSCs, focusing on quantitative analysis of glycolysis and oxidative phosphorylation using glucose without enzyme inhibitors. This protocol enables efficient comparison of energy metabolism among cell types, including undifferentiated PSCs, differentiated cells, and cells undergoing cellular reprogramming, and addresses critical issues, such as differences in basal metabolic levels and sensitivity to normalization, providing valuable insights into cellular energetics.
