Background: In view of the safety and effectiveness of butorphanol as a postoperative analgesic, we designed to compare its activity and side effects with those of ketoprofen, when administered intramuscularly. Methods: Ninety four patients, scheduled for elective total abdominal hysterectomy, received either ketoprofen 100 mg (ketoprofen group) or butorphanol 2 mg (butorphanol group) intramuscularly after surgery. For the first six hours after injection of butorphanol or ketoprofen, the patients were asked to reevaluate the intensity of pain, using numeric rating scale (NRS) and pain score. If the pain score was above 2, supplemental ketoprofen was administered IM. Incidence of side effects were also checked. Results: Butorphanol group showed lower NRS and pain score for the first four hours compared to ketoprofen group, but the incidence of drowsiness was higher in butorphanol group. There were no significant difference in the incidence of other side effects such as nausea and dizziness. In both group, there were neither respiratory depression nor pruritus. Conclusions: Butorphanol gave better relief of postoperative pain compared to ketoprofen. Butorphanol might be a useful drug for postoperative analgesia after hysterectomy with minor side effects.

Recently, Open Course Ware service area which offers free lecture materials has been steadily growing. This change comes from a paradigm shift of education service caused by the progress of ICT and a role change of consumers. Knowledge creation from higher educational institutions is slow compared to change of society. Therefore, consumers escape from one-sided education, and perform a new role of knowledge generation. Nevertheless, there is not much of academic research of Open Course Ware. Consequently, the paper is dedicated to empirical study on effect of perceived value, information system quality and brand trust on intention to continuous use. As implications for the research, as a practical point of view, the results-an economic side that offers contents for free of charge, a contents side that is fresh, various and substantial, a systematic side that makes customers to use the system easily, a service side which takes charge of customers support and brand trust affect satisfaction and intention to continuous use - can be used for establishment of executive strategies.

Perovskite type ceramic membranes which exhibit dual ion conduction (proton and oxygen ion conduction) can permeate water and can aid solving operational problems such as temperature gradient and carbon deposition associated with a working solid oxide fuel cell. From this point of view, it is crucial to reveal water transport mechanism and especially the nature of the surface sites that is necessary for water incorporation and evolution. $BaCe_{0.8}Y_{0.2}O_{3-{\alpha}}$ (BCY20) was used as a model proton and oxygen ion conducting membrane in this work. Four different catalytically modified membrane configurations were used for the investigations and water flux was measured as a function of temperature. In addition, CO was introduced to the permeate side in order to test the stability of membrane against water and $CO/CO_2$ and post operation analysis of used membranes were carried out. The results revealed that water incorporation occurs on any exposed electrolyte surface. However, the magnitude of water permeation changes depending on which membrane surface is catalytically modified. The platinum increases the water flux on the feed side whilst it decreases the flux on the permeate side. Water flux measurements suggest that platinum can block water permeation on the permeate side by reducing the access to the lattice oxygen in the surface layer.

Nobody denies that to detect a view of children agreeable to us is one of our tasks. Studying the Early Buddhist Scriptures, for the purpose of finding and the view of children entered the priesthood of Buddhism rooted deeply in our culture, I can find out the following conclusions. 1. Buddha regards that adults and children are same in that both of them are equally able to attain Nirvana, and he recognizes the differences between adults and children appeared in body and mind in the process of spiritual discipline. 2. He consideres that parent's worldly love is needed to the children priests below the age of 12. 3. He called priests over the age of 12 to 20 children priests, and he said that they have to be under a certain guard in particular, because unlike adults they have a lot of problem in the discipline process. 4. In the view of human being's growth and development, it is assumed that the group of children priests played a part as a group of spiritual discipline for youths. 5. It's regarded that the group of children priests also had function as a group of child welfare of today. 6. In other side, we can see Buddha's strict view of education for children priests, that is, even though they were children they had to discipline themselves thoroughly according to the view of values of Buddhism as far as they are priests who entered the temple. 7. Even if they are children, only minimal living things are permitted to them, and an ascetic life is required to them. In modern sense, how can such views be accepted and used? I think, this is our new task deeply looked into again in the standpoint of education of whole man rooted in religions psychology.

조건부대체 알고리즘은 ATSC의 융합형 3DTV 표준인 SC-MMH 시스템의 화질을 개선하는 방법으로서 ATSC에 의해서 표준화되었다. SC-MMH 시스템에서는 양안식 스테레오 영상을 구성하는 기준영상과 부가영상의 해상도 및 부호화 방식이 서로 다르게 정해진다. 3D 영상을 합성하기 위해 해상도가 낮은 부가영상을 확장함에 있어서 조건부대체 알고리즘을 적용하면 약간의 부가 정보를 추가함으로써 3D 영상의 화질이 대폭 개선된다. 이 과정에서 부가 정보는 쿼드트리 구조의 가변 크기 블록 단위로 처리되기 때문에 확장된 부가영상에는 시각적으로 거슬리는 블록화 현상이 발생할 수 있다. 본 논문에서는 SC-MMH 시스템의 수신기 측면에서 조건부대체 알고리즘에 의한 블록화 현상이 발생하는 경우를 분석하고 가변크기의 블록에 사용가능한 디블록킹 필터를 적용함으로써 블록화 현상을 효과적으로 억제할 수 있음을 실험을 통해 검증하였다.

Evaluations and treatments of nasal bone fracture have been mainly focused on aesthetic aspect, but nose has an important role as an airway. The purpose of this study was evaluation of nasal bone fractures in the view of nasal obstruction and its improvement after reduction. Acoustic rhinometry was applied to the 77 nasal bone fractured patients who received closed reduction from August 2002 to July 2003 and received closed reduction. This was tested twice, before and 6 days after reduction, for all 77 patients and additional acoustic rhinometry was also possible in 26 patients after 6 months. The analysis of acoustic rhinometry were based on data of minimal cross-sectional area(MCA) according to fracture sites(one side, both side and tip) and septal displacement. Mean MCA for all cases before reduction was $0.43{\pm}0.21cm^2$, which was 19% decrease compared to normal adult data($0.53{\pm}0.12cm^2$). Depending on fracture sites the MCA were $0.45{\pm}0.16cm^2$ for one side fracture, $0.35{\pm}0.18cm^2$ for both side fracture, and $0.42{\pm}0.25cm^2$ for tip fracture. The patients with septal displacement showed more severe obstruction than ones without septal displacement, $0.26{\pm}0.26cm^2$ and $0.46{\pm}0.10cm^2$, respectively. The MCA was improved up to $0.50{\pm}0.22cm^2$ after reduction and showed slight decrease after 6 month($0.48{\pm}0.23cm^2$). Based on the results of this study, nasal bone fracture really caused airway obstruction(19% decrease). Both side fracture showed more profound decrease than one side fracture and septal displacement was an important parameter which causes nasal obstruction. Closed reduction improved MCA by 14% right after reduction, and 11% after 6 month follow up.
