Limb body wall complex(LBWC) has been included in the spectrum of defects seen in early amnion rupture sequence. LBWC is a complicated fetal malformation with essential features of exencephaly or encephaloceles associated with facial clefts, lateral body wall defects with evisceration of organs, and limb defects. Our case is characterized by the absence of craniofacial anomalies and normal development of urogenital system comparing with other repoerted cases. We present a case of LBWC with a brief review of the literatures.

감성적 소비가치에 관한 연구 : 소비자혁신성과 신제품 수용도 및 감성적 소비가치 요소의 관계를 중심으로

황민우,정헌배 한국방송광고공사 2007 광고연구 Vol.0 No.77

과거 20~30년 동안 소비자행동 연구에 있어서 이성적 소비행위에 관심이 높았던 반면, 감성적 소비행위에 대해서 는 논의 자체가 미비하였다. 이러한 경향은 신제품 수용 및 소비자 혁신성에 관한 연구에 있어서도 마찬가지였다. 그러나 많은 경우에 있어 소비자의 의사결정행위는 이성적 판단을 통한 효용극대화보다는 감성에 근거한 정서적 만족감을 추구하고 있음을 볼 수 있다. 더욱이 최근에는 제품정보의 범람과 기술의 발달 및 제품품질의 동질화로 제품 간 차이가 무의미해짐에 따라 감성이 직접적인 의사결정 요인으로 제품선택에 영향력을 발휘하고 있다. 따라서 본 연구에서는 소비자 혁신성과 신제품 수용도 사이에서 감성적 소비가치의 매개적 역할과 감성적 소비가치 요소 간의 통합적 관련성을 밝혀 의사결정요인으로서의 감성의 중요성을 규명하고자 하였다. 이러한 내용을 파악하기 위해 소비자 혁신성과 감성적 소비가치의 관계, 감성적 소비가치 요소 간의 관계, 감성적 소비가치와 신제품 수용도의 관계에 대한 가설을 설정하여 검증하였다. 가설검증 결과, 소비자 혁신성이 감성적 소비가치에 영향을 미치고, 감성적 소비가치가 신제품 수용도에 영향을 미치는 것으로 나타나 감성적 소비가치의 매개적 역할이 확인되었다. 또한 감성적 소비가치 요소 간에도 부분적인 영향력이 존재하는 것으로 파악되었는데, 심미적 소비가치가 높을 수록 상징적 소비가치와 쾌락적 소비가치가 높은 것으로 나타났다. 반면, 상징적 소비가치는 쾌락적 소비가치에 유의한 영향을 미치지 못하는 것으로 나타났다. During past 2 or 3 decades, there has been more interest in a ration than in emotion in a theory of consumption behavior. This academic trend is similar to that in the study of new product adoption and consumer innovativeness. However in many cases, consumers, while shopping, pursuit affective satisfaction based on emotion rather than on utility maximization through rational judgement. As the recent overflow of product information, technology development, and homogeneity of product quality obscure the uniqueness of a product, emotion directly affects the product choice process as the purchase decision-making factor. Therefore, the purpose of this study is to verify the mediating role of emotional consumption value between consumer innovativeness and new product adoption, and to confirm integrated casuality among consumption value’s components-aestheticism, symbolism, and hedonism. To achieve these goals, 9 hypotheses are made on the relation between consumer innovativeness and emotional consumption value, on that between emotional consumption value and new product adoption, and on that among emotional consumption value’s components. As a result of proving 9 hypotheses, all hypotheses except one are supported. Mediating role of emotional consumption value between consumer innovativeness and new product adoption is proved by the consumer innovativeness, which affects the emotional consumption value, which affects the new product adoption. And, the partial casuality among the component of emotional consumption value is proved to exist, because the aesthetic consumption value had a strong positive relation with symbolic and with hedonic consumption value while the symbolic consumption value did not have a significant influence on hedonic consumption value.

A 28-year-old primigravida at 33 weeks gestation was referred to our hospital because of aggravation of seizures which occurred intermittently for the past 2 years. A brain magnetic resonance imaging scan taken at 33 weeks gestation showed a large brain tumor (7 × 5 × 4 cm) in the left high frontal lobe. She had a cesarean section under general anesthesia at 38 weeks and 1 day gestation. General anesthesia was induced with thiopental 250 mg, succinyleholine 75 mg and lidocaine 60 mg after a vecuronium 0.8 mg intravenous injection. The hyperventilation and mannitol used to reduce increased intracranial pressure (ICP) in this patient may be harmful and detrimental to the fetus before delivery. Achieving both ICP control and fetal well being at the same time during a cesarean section can be challenging to anesthesiologists. We report the anesthetic management of a cesarean section in a patient with a large brain tumor. (Korean J Anesthesiol 2002; 43: 515~519)

시상골 골절단술시 근심골편의 변위를 방지하기위한 lingual fracture technique

장헌수,안재진,우성도,김종필 大韓顎顔面成形再建外科學會 1994 Maxillofacial Plastic Reconstructive Surgery Vol.16 No.1

The sagittal split osteotomy of the mandibular ramus is a common procedure which has been used in the correction of mandibular deformities for a few decades. Although the technical improvements have increased the reliability and stability of SSRO procedure, the postoperative relapse is imperative and clinically more significant than any other complication. One of the major causes of the relapse is due to the displacement of the proximal segment during SSRO procedure, which is well documented in the literature. Therefore it is important to preserve the original position of the proximal segment during SSRO proced and maxillofacial fixation period. In the case of mandibular asymmetry, if one side of mandible is advanced and the other side of mandible is setback during SSRO procedure, the proximal segment in the advancement site will rotate laterally and the proximal segment in the setback site will rotate medially. For the prevention of the lateral rotation or flaring of the proximal segment in the advancment site. we deliberately fracture the posterior protion of the distal segment in green-stick fashion during SSRO procedure, and there is no need to fix the fractured lingual segment. We fix the two octeotomized bony segments in the buccal cortex area rigidly with adjustable monocortical plates and screws. During SSRO procedure the lingual fracture technique was applied to nine patients with severe mandibular asymmetry who underwent orthognathic surgery in our hospital since march, 1992. These clinical experiencies enable us to find the lingual fracture technique has the following advantages. 1. The proximal segment is displaced minimally. 2. The osteotomized bony segments are contacted intimately. 3. The postoperative relapse and the healing period are decreased.

Lovastatin(LV), one of the potent cholesterol-lowering agents, is an inactive lactone prodrug which is metabolized to its active open acid (Lovastatin acid. LVA). In order to optimize the assay procedure of LVA by high performance liquid chromatography(HPLC). solid phase extraction(SPE) method and protein precipitation method were employed for the pretreatment of plasma sample containing LV and LVA, and plasma sample was hydrolyzed under alkaline condition to transform all LV to LVA. Following pretreatment of plasma sample. 100ul of sample was injected onto a reversed-phase C_18 column and eluted with a acetonitrile-pH 3.0 phosphate buffer mixture(45:55 v/v) at a flow rate of 2.0ml/min. Ultraviolet detection was carried out at 238nm. It has been shown that all of LV in plasma was converted to LVA in vitro under alkaline condition. On SPE method, elution with acetonitrile-methanol mixture(75:25 v/v) indicated the highest recovery of LVA, but acid treatment of plasma sample before loading on SPE cartridge revealed little effect on recovery of LVA. Compared with two different pretreatment of plasma sample, SPE indicated better sensitivity and recovery.

肺 組織에서 胡桃 抽出液이 酸化性 細胞 損傷의 防禦棋戰에 미치는 影響

李佑憲,徐雲敎,鄭智天 동국대학교 한의학연구소 1997 東國韓醫學硏究所論文集 Vol.6 No.1

胡桃는 補陽藥으로써 下焦를 溫補하고 元氣를 攝納하며 潤肺腎하는 效能이 있어 오래된 虛寒咳嗽, 喘息의 治療에 사용되어 왔는데 肺 組織內에서 酸索遊離基들에 依한 細胞 損傷의 防止 여부를 알아보기 爲하여 酸化劑인 t-butylhydroperoxide(t-BHP)와 H₂O₂로써 細胞 損傷을 유발한 후 胡桃 抽出液의 抗酸化 效果 및 抗酸化 酵素의 活性에 미치는 影響과 酸素遊離基에 對한 직접 消去效果를 調査하였다. 이 결과 胡桃는 肺 組織에서 脂質의 過酸化를 抑制함으로 oxidant에 依한 肺浮腫 誘發을 防止할 수 있음을 보여주었고 細胞內 glutathione의 濃度 및 抗酸化 酵素 中 catalase 와 superoxide dismutase 活性에는 變化를 유발하지 못하였으나 glutathione peroxidase의 活性을 有意하게 增加시켰으며, superoxide radical과 hydroxyl의 生成을 減少시켰다. 따라서, 肺 組織에서 酸化性 細胞 損傷에 對한 胡桃의 保護 效果는 부분적으로 細胞內 抗酸化 酵素의 活性 增加와 酸素遊離基들을 직접 消去시키는 作用에 起因하는 것으로 사료된다. This study was undertaken to determine whether Juglandis Semen extraction(JS) has a protective effect against the lung cell injury caused by oxidants, t-butylhydroperoxide(t-BHP) and H₂O₂in rabbit lung slices. JS significantly prevented an increase in water content indured by t-BHP. Similarly, JS slgnificantly prevented the lipid peroxidation induced by t-BHP. Cellular concentration of glutathione, and the activities of catalbase and superoxide dismutase were significantly not altered by 5% JS. However, JS at 5% concentration significantly increased the glutathione peroxidase activity in oxidant-treated and control tissues. JS decreased directly the production of superxide or hydroxyl radical. These results indicate that JS prevents the cell injury and lipid peroxidation induced by oxidants in the lung. Such an antioxidant effort is attributed to enhancement of major endogenous antioxidant defence systems such as glutathione peroxidase and direct inhibition of oxygen free radical production.

Vitreous hemorrhage, which is the major cause of blindness in proliferative diabetic retinopathy, has been prevented clinically with laser photocoagulation. We reviewed 57 cases(98 eyes) of proliferative diabetic retinopathy which were treated by argon laser and followed up for more than 6 months. Of these 98 eyes, 81 eyes(83%) showed a satisfactory response after standard panretinal photocoagulation. 14 eyes(14%) revealed the vitreous hemorrhage after panretinal photocoagulation and higher incidence of vitreous hemorrhage in the cases of new vessel on the optic disc. In the cases(26 eyes) of new vessel on the optic disc, 2000 laser burns revealed lower incidence of vitreous hemorrhage(1/5, 20%) in comparison with 1500 laser burns(8/21, 38%). These results indicate that initial augmented laser therapy prevented the vitreous hemorrhage effectively.

먹이의 색깔과 맛이 조류(鳥類)의 먹이선택에 미치는 영향

박헌우,김수일 한국교원대학교 환경과학연구소 2004 환경연구논문집 Vol.- No.8

조류는 먹이에 대하여 색과 맛, 냄새로 먹이의 안전성을 확인하고 선택적으로 섭식하므로 먹이의 선책은 경험에 의해 달라질 수 있다. 본 연구는 조류가 먹이의 선택에 있어 맛과 색을 구별하고 이들의 학습능력의 정도를 곤줄박이(Parus varius), 되지빠귀(Turdus hortulorum), 멧새(Emberiza cioides), 바다직박구리(Monticola solitarius)4종을 통하여 알아본 결과이다. 실험 결과 색깔에 대한 반응은 종류마다 차이가 있는 것으로 나타났다. 가장 선호도가 높은 색으로 곤줄박이는 노란색, 되지빠귀는 녹색, 멧새는 무처리였고, 바다직박구리는 분홍색을 선호하였으며, 효과는 시간이 지날수록 더 강화되었다. 먹이의 색에 맛을 첨가한 실험에서는 곤줄박이와 바다직박구리는 쓴맛을 회피하였으며, 2주 후에는 회피정도가 더 심한 것으로 나타났다. 되지빠귀와 멧새는 초기 먹이를 주로 섭식 하였으나, 시간이 지날수록 단맛의 먹이를 먹는 비율이 높아졌다. 따라서 조류는 먹이의 색과 맛에 대하여 섭식 선호도를 나타내며, 먹이의 맛은 색보다 우위를 차지였고, 맛에 대한 경험의 효과는 시간이 지날수록 심화되는 것으로 나타났다. Most birds tend to forage their foods selectively checking the safety by color, taste or smell of items. Birds' food selection behavior may be therefore, learned and changed by the previous experiences of individual. This study is designed to test the effects of food color and taste on the choice of several passerine species: Varied Tit(Parus varius). Gray-backed Thrush(Turdus hortulorum). Meadow Bunting(Emberiza cioides) and Bine Rockthiush(Monticola solitaius). The color choice experiment was performed with food tablet with four different colors(red, scarlet, yellow, green), and no color added as a control. Food taste experiment was performed with bitter taste and sweet taste. The results showed that each species had different color choices: the best choice of Varied Tit was yellow. Meadow Bunting was control, and Blue Rockthrush was scarlet. The best choice on a specific color by each species sustained at least for two weeks. Results for taste added on colored foods showed that Varied Tit and Blue Rockthrush tend to avoid bitter taste and the tendency increased as days passed for two weeks. Gray-backed Thrush and Meadow Bunting favored firstly selected food choice, but the choice level gradually increased to sweetened food. This results indicate that birds take food selectively, taste take precedence over the color, and the effect of taste experience increase and persisted at least two weeks period.
