A 30-year-old man with morbid obesity (height: 176 cm, body weight: 100 kg, body mass index: 32.28) was scheduled for reconstruction of the mandibular fracture. During induction of general anesthesia and nasotracheal intubation, we experienced massive epistaxis, hypoxemia and difficult airway management. Fortunately, we performed oro-tracheal intubation with direct laryngoscopy and it barely succeeded. He recovered without any residual complications and rescheduled seven days later and we successfully performed awake fiberoptic nasotracheal intubation. The patient discharged on the fourth postoperative day.

A real $m{\times}n$ matrix A is called an L-matrix if every matrix in its qualitative class has linearly independent rows. Since the number of the sign pattern matrices of the given size is finite, we can list all patterns lexicographically. In [2], a necessary and sufficient condition for a matrix to be an L-matrix was given. We presented an algorithm which decides whether the given matrix is an L-matrix or not. In this paper, we develope an algorithm and C-program which will determine whether a given matrix is an L-matrix or not, or an SNS-matrix or not. In addition, we have extended our algorithm to be able to classify sign-pattern matrices, and to find barely L-matrices from a given matrix and to list all $m{\times}n$ L-matrices.

The disabled peoples increase in number by disasters from the industrialization and urbanization. The physically handicapped people experience many difficulties in using the facilities in the public buildings. So, this survey proposed the necessary conditions for the handicapped peoples to use without any trouble in public buildings. The objects of investigation were public buildings, village offices, a public library, synthesis hospitals banks, an express bus station, a wedding building, a railroad station etc.. Conclusions were as follow \circled1 The most of buildings were established access road in regulations but parking area was established inappropriately in regulations \circled2 The most of convenience facilities were concentrated on first floor but were established barely in more than second floor. \circled3 The most of convenient facilities were established in appropriately in regulations. \circled4 The other convenient facilities(reception desk, ticket agency, work desk etc.) were not established nearly in the buildings of investigation.

The paper describes the results of an experimental and numerical investigation into the structural and damage response of sandwich composites to low-velocity impact. Sandwich panels consisting of laminated composite skins with three different layups bonded to a PVC foam core were subjected to impact at various energy levels corresponding to barely visible impact damage (BVID) in the impacted skins. Damage assessment analyses were performed on the impacted panels to characterise the extent and the nature of the major failure mechanisms occurring in the skins. The data collected during the experimental analyses were finally used to assess the predictive capabilities of an FE tool recently developed by the authors for detailed simulation of impact damage in composite sandwich panels. Good agreement was observed between experimental results and model predictions in terms of structural response to impact, global extent of damage and typical features of individual damage mechanisms.

As a general rule for evaluating dependability of a system, reliability is commonly considered which barely rays attention to the system behavior, however the estimation is based on the assumption of a fault-frost system, which may be impracticable and inaccurate especially for complicated system. This paper introduces a security and dependability integrated approach to analyze the availability of a fault-active system both from dependability and security points of view. Two fault modes involved are discussed about the impairment to the system reliance. The approach can be well applied to estimate and quantify the attribute of system robustness with the help of Markov chain process, which is good at solving status related problem. The comparison result between dual system and IEC61850-based almighty backup system is shown to sup-port the suggested approach.

Nitric oxide synthase (NOS) has been reported in uterus. We examined the expression of the NOS isoforms, constitutive endothelial (eNOS) and inducible NOS (iNOS), in bovine uterus by immunohistochemistry. eNOS immunoreactivity was localized predominantly to the endothelial cells that line uterine microvessels and to endometrial glandular epithelial cells, but was barely detectable in endometrial stromal cells. iNOS immunostaining was detected in glandular epithelial and stromal cells in the endometrium and in the endothelial cells of myometrial blood vessels. These findings suggest that both eNOS and iNOS may play important roles in the physiology of the uterus, possibly by generating NO.

Congenital lobar emphysema is one of the many causes of the respiratory distress syndrome in infant and an unusual condition barely mentioned before 1949, and only 166 cases were reported till 1967 in English literature This report describes a one-month-old boy who had a congenital middle lobar emphysema. The middle lobectomy was the operation for this case with complete cure.

Starting with Kubo's formula and using the projection operator technique introduced by Kawabata, EPR lineprofile function for a $Mn^{2+}$-doped wurtzite structure GaN semiconductor was derived as a function of temperature at a frequency of 9.49 GHz (X-band) in the presence of external electromagnetic field. The line-width is barely affected in the low-temperature region because there is no correlation between the resonance fields and the distribution function. At higher temperature the line-width increases with increasing temperature due to the interaction of electrons with acoustic phonons. Thus, the present technique is considered to be more convenient to explain the resonant system as in the case of other optical transition systems.

Forage barley was developed for decreasing the import of forages, and increasing the farmer' income about ten years ago. Nevertheless of higher of farmer' income, the forage barley' area is slowly increased because of lacking of barely seeds. In order to suggest the plan of the urgent spreading on forage barley, the seed-gathering of forage barley was cultivated on 14-provinces and 291ha on 2009. The cultivation area of kyeungnam, kyeungbuk and chunnam province was more than other provence. The youngyang cultivar was cultivated more than orher cultivar. Seed-gathering amount of Youngyang, Uhoo and Yooyun cultiva was 364,213 and 303MT respectively. There were several problems for seed-gathering of forage barley which were the delay of seeding time and the more seeding amount, and the higher seed drying temperature than that of standard manual.

The effects of various intensity of W-B on barley seeding were investigated by PS I and II activities and chlorophyll fluorescence. The Inhibitory effect of UV-B radiation on electron transport activity was Increased as the intensity of UV-B Irradiation was increased. Especially, PS I is more sensitive to UV-B radiation than PS I is. By the addition of uncle electron donor, DPC, to the chloroplasts of the barley seedlings treated with UV-B, the photoreduction of DCPIP was recovered by only 1 IBI on electron transport activity. However, the activity of PS II was Inhibited by 45% by the treatment with UV-B, but recovered it only 11% by the addition of DPC. These suggest that other sites besides the oxidation site of PS II may be affected more by UV-B Irradiation. As the intensify of UV-B was Increased, Fo was Increased while Fv was decreased, and thus Fv/Fm was decreased. This means that photochemical efficiency was reduced. With this parameters, it might be that UV-B radiation affected adversely to around PS II.
