최근 모바일 앱에서도 오픈소스 소프트웨어를 이용한 개발이 활발하게 이루어지고 있다. 오픈소스 모바일 컴포넌트의 경우 사용자 인터페이스 구현을 위한 컴포넌트의 재사용성이 용이하다는 이유로 기능적 역할의 컴포넌트보다 더욱 많이 사용되는 경향이 있다. 이런 특징으로 인해 기존의 오픈소스 소프트웨어 선정절차나 상용 컴포넌트 선정절차 두 가지 연구 모두 오픈소스 모바일 컴포넌트 선정에 그대로 적용하기에는 무리가 있다. 본 논문에서는 기존에 연구된 오픈소스 소프트웨어 선정절차를 모바일 컴포넌트 선정에 적합하도록 수정, 보완하였다. 본 연구는 모바일 앱을 개발할 경우, 요구되는 기능을 충족하는 오픈소스 컴포넌트를 쉽게 검색하고 선정할 수 있는 효율적인 절차를 제시함으로써 모바일 앱 개발의 생산성을 높여줄 수 있다. The way of mobile apps development using open source software have been becoming increasingly popular recently. In opensource mobile User Interface components case, there is tends to much more be used than mobile functional components. Because it is more easier that the reusability for implementation of User Interface. The problem is to apply as an open source mobile components selected for this reason all of the existing two studies. It is an open source software selection process and selection procedures shelf components. We revise to conform to existing mobile components selected for the study on open source software selection process in this paper. Can help increase the productivity of the mobile app development by the open source components to meet the functional requirements when developing mobile apps that can be easily retrieved and presented the selection process of this study is effective.

The purpose of this report is to present the results of clinical observations upon 21 surgical cases with tic douloureux (female 13, male 8) during the period from January, 1960 to August, 1972 at the Department of Neurosurgery, Seoul National University Hospital, Seoul, Korea. The average age at onset was 48 years of age ranging from 22 to 66 years. The average duration from onset to operation was 5 years. The frequency of involvement was the highest in the maxillary division, next was maxillary and mandibular division, and none in the ophthalmic division. Whole division was involved in one case. Right-sided involvement predominated by a ratio of 2 to 1 and bilateral involvement was found in only one case. Extraction of innocent teeth, ungratifying operation upon paranasal sinus had been carried out in 11 cases as consequence of misdiagnosis. Alcohol injection of peripheral branches of trigeminal nerve and medical treatment produced short-lived or non-effectiveness. Trauma to ipsilateral mandible arid epidermoid cyst at cerebellopontine angle seemed to be the cause of tic douloureux in 2 cases, respectively. Major complications observed in Frazier's method group, were paresthesia, facial nerve palsy, partial paralysis of motor root, and recurrence of neuralgia. All of the peripheral nerve avulsion group developed recurrence of pain within three years. Mild decrease of corneal reflex was noted in two cases of Dandy's method group. Posterior fossa operation stands in superiority, when it is considered that some pathologic lesions are frequently found in the posterior fossa, that motor root is less frequently injured, and that the light touch is so fairly preserved in all three divisions that the least damage to the cornea is expected.

The double-lumen tube is widely used in various kinds of cardiothoracic surgery as a facilitation for easier procedures. SilbronchoⓇ (Fuji systems, Tokyo, Japan) double-lumen tube, which is made of flexible silicone material, reduces injury to the tracheal and bronchial mucosa during intubation. The bronchial lumen is wire-reinforced to maintain tip angulation and prevent bending or obstruction. However, its increased flexibility resulted in distortion,especially when we encountered resistance to passage. We document an unusual complication case which involved folding of the endobronchial segment of the double-lumen tube after blind intubation in difficult airways. (Anesth Pain Med 2011; 6: 154∼156)

Intrasellar or pituitary abscess was first reported about a century ago, after then once relatively common but now is rare. Since 1925, about 50 cases have been reported in the literatures, of which characters were variable, but clinically very similiar to one of pituitary tumor. So they were often diagnosed preoperatively as pituitary tumor. Several pathogenic factors were postulated in relation to clinical aspects. We had recently experienced a case of pituitary abscess combined with chromophobe adenoma. A 28 years old clerkman was admitted to our hospital with complaints of impaired ejaculation and visual disturbance. Clinical aspects and diagnostic studies gave us a strong impression of pituitary tumor. Upon surgery we found a cystic mass in pituitary region, of which aspiration showed whitish-gray, tenacious and liquid material. Many polymorphous leukocytes were noted by direct smear, but no microorganisms were detected in culture. He had postoperatively suffered from transient polyuria and polydipsia, which soon disappeared under the medication of Esidrex. He was discharged from this hospital with recommendation of radiation therapy. Clinical features and treatment were also discussed with review of ever reported cases.

Synergy effect of legal highs with antibiotics
손효정,유선희,박초희 한국응용과학기술학회 2020 한국응용과학기술학회지 Vol.37 No.6
In this study would like to find extending or increasing the efficacy of the antibiotic substance for the strains with resistance to antibiotics or persister cells by inhibition of the resistance. This study was used different species of ‘legal high’ plants leaves from Leonotis leonurus, Mitragyna speciosa, and seeds from Ipomoea murucoides with antibiotics which are Amoxicillin, Chloramphenicol, Ciprofloxacin, Kanamycin, Oxacillin, and Vancomycin. Legal highs were extracted with methanol. Minimum inhibitory concentration(MIC) testing for a range of antibiotics with extracts of plant was fulfilled by broth dilution methods. In this essay, it was determined in a microdilution assay utilizing suspended in ISB up to a final concentration of 512µg/ml in 96 wells microtitre plates, threefold and serial dilutions. After that, the microplates were kept in incubator between 35°C and 37°C for overnight. Leonotis leonurus, Mitragyna speciosa, and Ipomoea murucoides of Legal highs (512µg/ml) investigated small activity to inhibit against pathogens which are susceptible Staphylococcus aureus, resistant Staphylococcus aureus, susceptible Enterococcus faecalis, resistant Escherichia coli.

대망전위에 의한 대뇌맥관 신생에서의 지주막절개의 효과에 대한 연구
손효정,김현집,정희원,최길수,심보성 대한신경외과학회 1985 Journal of Korean neurosurgical society Vol.14 No.1
Cerebral vascularization by omental transposition or transplantation to the brain has been applied in experimental and clinical cerebral ischemia. However, in these operative procedures, it has not been discussed whether arachnoid dissection would produce significant benefit in cerebral vascularization. The purpose of this experiment is to observe the effect of arachnoid dissection upon cerebral vascularization in omental transposition to the brain. Forty healthy adult cats underwent partial craniectomy with dural opening and were divided into four experimental groups; Group 1-control group, Group 2-temporal muscle covering over the brain surface. Group 3-omental transposition to the brain surface and Group 4-omental transposition with arachnoid dissection. After 3weeks of clinical observation on the occurence of convulsive seizures, animals were subjected to permanent occlusion of middle cerebral artery by transorbital approach. For 24 hours, neurologic deficits were checked and then animals were sacrificed to evaluate the size of cerebral infarction. The results were as follows: 1) Convulsive seizures were observed in 2 cases among all the animals, but there was no statistically significant difference in the occurence rate among each group. 2) Animals in groups of omental transposition revealed mild neurologic deficits, as compared to those in the control group and the group of temporal muscle covering. 3) There was no statistically significant difference in the size of cerebral infarction between the control group and the group of temporal muscle covering. But in groups of omental transposition, the size of infarction was remarkably small as compared to the control group and the group of temporal muscle covering(P<0.05). 4) Of the two groups of omental transposition, the group of arachnoid dissection showed smaller size of cerebral infarction (P<0.05). 5) There was a tendency that the infarcted area enlarged progressively as neurologic deficits were severely impaired, but the difference was not statistically significant. 6) Cerebral vascularization was most effectively produced in the group of omental transposition with arachnoid dissection.
