Objective: The objective of this research was to develop a guideline for more effective use of physical restraint on patients in the intensive care unit and training the nurses on it and applying it on clinical practice to assess its effectiveness. Method: This research analyzed the before and after effect of the development of a guideline for physical restraint by dividing the category into nurse and patient. In the case of nurse, a comparison of knowledge and nursing service regarding the use of physical restraint from before the training on physical restraint guideline(Jan. 2011) and after the training on physical restraint guideline(Dec. 2011) was made. In the case of patient, a comparison of physical restraint usage rate and average usage time, the number of unplanned extubation cases were compared from before the use of physical restraint (Jan.~Apr. 2011) and after the use of physical restraint (Sep.~Dec. 2011) were made. Result: After the training on the physical restraint guideline, the knowledge of the nurse and the nursing practice showed notable improvement by (p<0.000) and (p<0.048) respectively and in patient, physical restraint usage rate and average time of usage decreased by (p<0.001) and (p<0.001) respectively. And despite the decrease in the number of cases in which the physical restraint was used, the number of unplanned extubation cases remained the same. Conclusion: Physical restraint guideline training and guideline usage can be stated to have brought out positive effect in both the nurse and patient. In order to maintain such positive effects, continuous training is necessary and continuous revaluation is necessary, regarding knowledge and nursing practices.

The relationship between menopause and effective disorders have not been well known, But there is ample evidence for action of estrogen on the dopaminergic cholinergic, Gamma Aminobutyric Acid and various neuropeptide systems. We try to ealuate the effects of oophorectomy and estrogen replacement therapy on β-endorphin immunoreactivity. Sprague-Dawley rats, weighing 250-300gm were devide into sham operation, bilateral oophoretomy and bilateral oopharectomy with estradiol cypionate(10㎍/㎏) treatment group. After one month, brain was removed and processed for β-endorphin immunostain with Avidin-Biotin method. Β-Endorphin immunostaining in both medial basal hypothalamus and nucleus accumbens were decreased in oophorectomized rats compared to those of sham operation. In estradiol treated rats, endorphine immunostaining in medial basal hypothalamus was decreased but sama as sham operation in Nucleus accumbens. These results suggest that surgical menopause causes the decrease of β-endorphin immunoreactivity while estrogen replacement prevent the decrease of β-endorphin immunoreactivity in nucleus accumbens. These findings may partly explaining changes in affective state in some women after menopause.

Choi, Jung Won,Lee, Ji Yeoun,Phi, Ji Hoon,Wang, Kyu-Chang,Chung, Hyun-Tai,Paek, Sun Ha,Kim, Dong Gyu,Park, Sung-Hye,Kim, Seung-Ki Journal of Neurosurgery Publishing Group 2014 Journal of Neurosurgery: Pediatrics Vol.13 No.6

<B>Object</B><P>Neurofibromatosis Type 2 (NF2) is an autosomal-dominant inherited disease, characterized by multiple neoplasia syndromes, including meningioma, schwannoma, glioma, and ependymoma. In this report, the authors present their clinical experience with pediatric NF2 patients. In particular, they focused on the clinical course of vestibular schwannoma (VS), including the natural growth rate, tumor control, and functional hearing outcomes.</P><B>Methods</B><P>From May 1988 to June 2012, the authors recruited patients who were younger than 18 years and fulfilled the Manchester criteria. In total, 25 patients were enrolled in this study. The authors analyzed the clinical course of these patients. In addition, they measured the natural growth rate of VS before any treatment in these children with NF2. Then, they evaluated the tumor control rate and functional hearing outcomes after the treatment of VS.</P><B>Results</B><P>The mean age at the onset of NF2-related symptoms was 9.9 ± 4.5 years (mean ± SD, range 1-17 years). The mean age at the diagnosis of NF2 was 12.9 ± 2.9 years (range 5-17 years). The mean follow-up period was 89.3 months (range 12-311 months). As initial manifestations, nonvestibular symptoms were frequently observed in pediatric patients with NF2. The mean natural growth rate of VS was 0.33 ± 0.41 cm<SUP>3</SUP>/year (range 0-1.35 cm<SUP>3</SUP>/year). The tumor control rate of VS was 35.3% at 3 years after Gamma Knife surgery (GKS). The actuarial rate of useful hearing preservation was 67% in the 1st year and 53% in the 5th year after GKS.</P><B>Conclusions</B><P>Clinical manifestations in children with NF2 were highly variable, compared with their adult counterparts. The natural growth rate of VS in children is slow, and this oncological feature may explain the diverse clinical manifestations besides vestibular symptoms in children with NF2. The treatment outcome of GKS for VS in children with NF2 was not favorable compared with previous reports of affected adults.</P>

This study examined the consciousness of husbands and wives on babies` cries and its factors which have impacts on their emotional perceptions. For this study, infants` cries were recorded with the participation of 136 pregnant women and 76 husbands, and they conducted self-evaluations regarding their emotional perceptions and personal characteristics. The stimulus used to exhibit the cries of infants were from eighteen recorded cry sample under three situations (hunger, pain, and mother`s absence) with six healthy infants (three male and three female) who are over six months. Also, this study dealt with the relationship between emotional assessment and the personal characteristics of mothers and fathers. As a result, the experience of child-rearing has a positive influence on the emotional cry perceptions of husbands and wives, and there was no sex difference in their emotional cry perceptions. A change of recognition, “being parents,” has impacts on emotional cry perceptions, but the major factors increasing these impacts depend on the physiological changes of pregnant women and their personal characteristics.

A case of generalized fixed drug eruption caused by diclofenac

( Ho Jung Lee ),( Ji Yeoun Shin ),( Woo Il Kim ),( Euy Hyun Chung ),( Sang Hoon Lee ),( Moon Kyun Cho ) 대한피부과학회 2019 대한피부과학회 학술발표대회집 Vol.71 No.1

Fixed drug eruption is caused by culprit drug, and presents circular erythematous plaque. It is characterized by recurrence at the same site by re-administration of the same drug. It is known to account for 11-30% of adverse drug adverse reactions. The patient was a 82-year-old woman who presented with multiple erythematous plaques at both thighs, right legs, and back, and she complained about pruritus. The patient was taking Diclofenac for arthralgia twice daily for 3 days. A few years ago, she had a history of skin lesions similar to those after taking anti-inflammatory drugs. The biopsy specimen at right thigh showed prominent vacuolar degeneration in basilar layer, and edema and perivascular inflammation in papillary dermis. Inflammatory cells were composed of lymphocytes mostly, and several eosinophils were observed, too. Pigmentary incontinence was also observed. Fixed drug eruption mostly presents single lesion, but rarely, cases of generalized fixed drug eruption were reported, too. After the skin lesion has disappeared, hyperpigmentation often occurs. Most common drugs include NSAIDs, tetracycline, sulfonamide, and anticonvulsants. Until now, generalized fixed drug eruption caused by diclofenac have not been reported in Korea. We report this case because we think it is a rare case.

오늘날 세계 에너지 시장에서는 친환경 에너지의 중요성이 대두되고 있다. 수소 에너지는 미래의 청정에너지원이며 무공해 에너지원 중 하나이다. 특히 수소를 이용한 연료전지 방식은 재생에너지의 유연성을 높여주고 장기간 에너지 저장 및 변환이 가능해서 화석 자원의 사용에 따른 환경문제와 자원의 고갈로 인한 에너지 문제를 동시에 해결할 수 있는 방안으로 판단된다. 본 연구의 목적은 플라즈마를 이용하여 효율적으로 수소를 생산하는 방안으로, 온도에 따른 개질반응과 수율을 확인하여 DME(Di Methyl Ether)개질의 최적화 방안을 연구하는데 있다. 연구 방법은 2.45 GHz의 전자파 플라즈마 토치를 사용하여 청정 연료인 DME를 개질하여 수소를 생산하고. 저온 조건(T3 = 1100℃), 저온 과산소 조건(T3 = 1100℃), 고온 조건(T3 = 1376℃)에서 가스화 분석을 진행하였다. 저온 가스화 분석을 통해 1100℃ 근처에서는 불안정한 개질 반응으로 인해 메탄이 발생하는 현상을 확인하였고, 저온 과산소 가스화 분석은 저온 가스화 분석과 비교하였을 때 수소는 적으나 이산화탄소는 많은 것을 확인할 수 있었다. 고온에서의 가스화 분석을 통해 1200℃ 이상에서는 메탄이 발생하지 않았고 약1150℃ 부터 메탄이 발생하는 것을 알 수 있었다. 결론적으로 개질반응시 온도가 높을수록 수소의 비율이 높아지나 CO 비율은 증가하는 것을 볼 수 있었다. 그러나, 가스화기의 구조적인 문제로 인해 열손실과 개질의 문제가 발생함을 확인하였다. 향후 연구의 발전 방향으로는, 가스화기 개선을 통해 불완전한 연소를 줄여 높은 수율의 수소를 얻고 일산화탄소, 메탄과 같은 기체의 발생을 낮출 필요성이 있는 것으로 판단된다. 본 연구에서 제안하는 DME를 수증기 플라즈마 개질하여 수소를 생산하는 최적화 방안이, 향후 친환경, 신재생 에너지를 생산하는데 의미있는 기여를 할 수 있을 것으로 기대한다. In today"s global energy market, the importance of green energy is emerging. Hydrogen energy is the future clean energy source and one of the pollution-free energy sources. In particular, the fuel cell method using hydrogen enhances the flexibility of renewable energy and enables energy storage and conversion for a long time. Therefore, it is considered to be a solution that can solve environmental problems caused by the use of fossil resources and energy problems caused by exhaustion of resources simultaneously. The purpose of this study is to efficiently produce hydrogen using plasma, and to study the optimization of DME reforming by checking the reforming reaction and yield according to temperature. The research method uses a 2.45 GHz electromagnetic plasma torch to produce hydrogen by reforming DME(Di Methyl Ether), a clean fuel. Gasification analysis was performed under low temperature conditions (T3 = 1100°C), low temperature peroxygen conditions (T3 = 1100°C), and high temperature conditions (T3 = 1376°C). The low temperature gasification analysis showed that methane is generated due to unstable reforming reaction near 1100℃. The low temperature peroxygen gasification analysis showed less hydrogen but more carbon dioxide than the low temperature gasification analysis. Gasification analysis at high temperature indicated that methane was generated from about 1150°C, but it was not generated above 1200°C. In conclusion, the higher the temperature during the reforming reaction, the higher the proportion of hydrogen, but the higher the proportion of CO. However, it was confirmed that the problem of heat loss and reforming occurred due to the structural problem of the gasifier. In future developments, there is a need to reduce incomplete combustion by improving gasifiers to obtain high yields of hydrogen and to reduce the generation of gases such as carbon monoxide and methane. The optimization plan to produce hydrogen by steam plasma reforming of DME proposed in this study is expected to make a meaningful contribution to producing eco-friendly and renewable energy in the future.
