        Diabetic encephalopathy is a major complication with cognitive impairment and neurodegeneration in patients with type 1 or type 2 diabetes mellitus (DM). DM-induced glucolipotoxicity is a risk factor for Alzheimer’s disease–like phenotype, including amyloidogenesis, tau hyperphosphorylation, and neuronal apoptosis. Although the detailed mechanism underlying the pathogenesis of diabetic encephalopathy remains unclear, mitochondrial oxidative stress is emerging as a key factor for diabetic complications and neurodegeneration. A deeper understanding of the regulatory mechanism of mitochondrial oxidative stress under hyperglycemic conditions will provide insights into the development of therapeutic strategies for diabetic encephalopathy. Here, we review the role of mitochondrial oxidative stress in diabetic encephalopathy and the regulatory mechanisms by which high glucose induces the generation of mitochondrial reactive species oxygen species in neuronal cells. This review also summarizes the mitochondrial-dependent and -independent pathways (O-linked-N-acetylglucosaminylation, calcium, and glycogen synthase kinase 3β signaling) that regulate mitochondrial oxidative stress in a DM model.

        농촌진흥청 국립원예특작과학원에서는 2018년 분홍색계 소 형 호접란 ‘Tiny Bell’을 육성하였다. 2010년 진분홍색 다화 성 소형 품종 Phalaenopsis ‘D07PN16’와 연분홍색 소형종 P. ‘D03PN22’를 모본과 부본으로 교배하였다. 2014년 생육이 우 수하고 화색, 화형, 꽃대수 등 개화 특성이 우수한 ‘10531-53’ 개체를 선발하여 기내 화경배양을 통해 증식하였다. 2014년부 터 2018년까지 1차, 2차특성검정을 통해 품종의 안정성과 균 일성을 확인한 후 ‘Tiny Bell’로 명명하였다. 이 품종은 밝은 보라빛 분홍색(RHS, PVGN80A)을 띄며, 가장자리에 백색무늬 를 가지는 것이 특징이다. 평피기 형태의 꽃은 길이와 폭이 각각 3.89, 4.01cm이며, 총상화서로 분지가 발생한다. 1개의 꽃대에 19.7개의 소화가 착생하여 꽃 수가 많이 달리는 다화 성이며, 꽃대 길이는 28.48cm정도이다. ‘Tiny Bell’은 생육시 잎이 수평으로 자라며 길이와 폭은 각각 13.1cm, 5.3cm였다. 신품종인 ‘Tiny Bell’은 소형 분화용으로 이용 가능할 것이다.

        There is a growing global interest in food choices that could affect health. Consumer food choices are dictated by numerous factors such as attitudes, beliefs, desires and preferences stemming from psychological and physiological attributes. The present study aimed to understand consumers’ internal perceptions about cream soup, cream sauce, and tomato sauce using ZMET (Zaltman’s Metaphor Elicitation Technique). The 9 step ZMET interview process was conducted for a sample of 36 consumers (12 consumers for each sauce). A content analysis of the survey results was carried out. From this, 56 concepts of cream soup were derived, and 15 constructs that met with the agreement of more than one-third of the total sample consumers were extracted. These 15 constructs included ‘Soft’, ‘Recollection’, ‘Familiar’, ‘Warm’, ‘Comfortable’, etc. Similarly, for cream sauce, 67 concepts and 20 constructs ‘Silky’, ‘Warm’, ‘Restaurant’, ‘Family’, ‘Memory’, etc. were deduced. A total of 66 concepts and 20 constructs for tomato sauce ‘Sourness’, ‘Sauce Bottle’, ‘Pleasant’, ‘Ingredient’, ‘Cooking’, etc. were derived. The analysis of consumers’ consensus maps through this study provides a deep and useful understanding of consumers and their latent needs. Also, the results of this study indicate that exploring consumers’ internal perceptions is critical to understanding their healthy food choices. This can be used as basic data for formulating marketing strategies.

        Persistent left cranial vena cava (PLCVC) is a remnant vessel connected with the coronary sinus and draining into the right atrium. A 3-month-old intact male Bichon Frise was evaluated for the presence of a mechanical murmur auscultation in the local animal hospital. No significant clinical signs were present on physical examination except mechanical murmur. Patent ductus arteriosus (PDA) was diagnosed in the imaging procedure. During the left thoracotomy, PLCVC was found. The vascular malformation made the surgical process difficult by hiding PDA from the left thoracotomy surgical view. PLCVC and the vagus nerve was carefully dissected and lifted to secure a clear surgical view of PDA. The ductus arteriosus was ligated. Computed tomography angiography (CTA) was performed postoperatively. On CTA, left brachiocephalic vein retaining connection with the coronary sinus draining into the right atrium was observed. CTA is highly recommended for dogs with PDA to provide better postoperative results.

        최근 인터넷 문화의 발달과 디지털 게임이 급속도로 발전하고 있다. 그에 따라 플랫폼의 변화도 일어나고 있으며 디지털 게임의 장르 또한 많이 세분화되며 남녀노소 즐길 수 있는 문화가 되었다. 그 중에서도 다중 이용자 온라인 롤플레잉 게임(Massive Multi-player Online Role Playing Game, MMORPG)이 크게 성장하며 이용자의 수가 급증하였다. 이 다중 이용자 온라인 롤플레잉 게임(MMORPG)은 수많은 사람들이 가상공간에서 만나 함께 게임을 즐길 수 있는 장르로, 가상공간에서 소통 및 관계를 맺기에 최적이라는 특징을 갖고 있다. 그러나 과거엔 콘텐츠적 특성이 폭력적, 선정성이 강해 남성 이용자들의 전유물이라는 경향이 강했으나 최근엔 여성 이용자들이 꾸준히 증가하고 있다. 이에 관한 여성 이용자들의 MMORPG 게임 콘텐츠에 대한 선호양상을 연구하고자 한다.
