심근관류 스캔에서 부하영상에 비해 휴식영상에서 오히려 심근관류가 감소되어 보이는 현상을 역재분포라고 하며, 심근관류 스캔시 드물지 않게 관찰되나 아직 이 현상의 기전이나 의미는 확실히 밝혀진 바 없다. 이에 저자들은 디피리다몰부하 T1-201 및 Tc-99m MIBI 심근관류 SPECT에서 역재분포현상의 존재 유무를 알아보고, 또 이 현상이 어떤 경우에 나오는지 그 내용을 파악하기 위하여 1992년 9월부터 1994년 1월까지 전남대학교병원 핵의학과에서 시행하였던 심근관류 SPECT를 시행한 1462명을 대상으로 본 연구를 시행하여 다음과 같은 결과를 얻었다. 1) 대상환자 1462명중 168명(11.5%)에서 역재분포를 보였으며, T1-201을 사용한 환자는 463명 중 44명(9.5%), Tc-99m MIBI를 사용한 환자는 999명 중124명(12.4%)에서 역재분포를 보였다. T1-201 및 Tc-99m MIBI를 사용한 양군간에 역재분포 빈도수는 통계학적 유의한 차이는 없었다(p>0.05). 2) 심근관류 SPECT상 역재분포를 보였던 168명 중 관동맥조영술로 확진된 65명(T1-201 21예, Tc-99m MIBI 44예)을 질환별 분류를 하였다. T1-201과 Tc-99m MIBI를 사용한 모든 환자에서 재혈관화후 (53.9%), 관동맥질환(24.6%, 재혈관화후 및 심근경색 제외), 심근경색(12.3%) 그리고 정상 관동맥(9.2%) 순으로 관찰되었으며, T1-201 및 Tc-99m MIBI 양군간에 질병양상에 따른 통계학적 유의한 차이는 없었다. 3) 역재분포를 보인 부위를 좌심실 전벽, 중격, 하벽, 측벽 및 심첨부로 나누어 분석해 보면, 중격 32(39.5%), 하벽 24(29.6%), 전벽 12(14.8%), 심첨부 7(8.7%), 그리고 측벽 6(7.4%)의 순으로 나타났다. 4) 관동맥협착의 정도와 역재분포 빈도와의 상관관계를 알아보기 위하여, 역재분포를 보인 부위와 관련된 관동맥분지 30개를 협착정도별로 분류하였다. 협착의 정도와 역재분포의 빈도와는 상관관계를 보이지 않았으며, T1-201과 Tc-99m MIBI군 사이에도 분포의 차이가 없었다. 역재분포를 보인 부위와 관련된 관동맥 분지별로 보면 좌전하행동맥이 18예로 가장 많았고, 다음 이 우관동맥(10예), 좌회선동맥(4예)순이었다. 5) 역재분포를 보인 환자중 좌심실의 벽운동성을 관찰할 수 있었던 27명의 환자 중 12명은 정상벽운동, 12명은 저운동, 그리고 3명에서 이운동 소견을 보였다. 6) 역재분포를 보인 부위에 측부혈행 유무를 관찰 할 수 있었던 30예 중 측부혈행이 있었던 예는 4예에 불과하였다. 7) T1-201 심근관류 SPECT시 휴식기 T1-201 재주사를 시행한 14예 중 재주사에 의해 역재분포 부위에 섭취 증가를 보인 예는 10예였다. 결론적으로, 역재분포는 여러가지 병태생리적인 기전에 의해 나타날 수 있는 소견으로 보이며, 그 임상적 의의는 심근관류검사를 시행한 환자의 병력에 따라 판단하여야 할 것으로 사료되었다.

Patients with obstructive sleep apnea (OSA) often have more aggravated symptoms in the supine position. We tried to investigate the clinical characteristics and the predictive factors for positional OSA. Polysomnographic data were reviewed for OSA patients (apnea hypopnea index, $AHI{\geq}5$) from April, 2008 to April, 2011 at the Asan Medical Center. Clinical data, comorbid medical condition data and questionnaires (SF-36, MFI-20, ESS, BDI, STAI) were assessed. All patients were classified into two groups: positional patients (PP) group and non-positional patients (NPP) group. PP was defined as a patient who had the AHI in the supine position was at least twice as high as that in the lateral position. The body position of patients was confirmed by sleep position sensor and video monitor. All patients had at least 30 minutes of positional and 30 minutes of non-positional sleep. We compared clinical, medical, polysomnographic data, and questionnaire results between two (PP and NPP) groups and investigated predictive factors for the PP group using binary logistic regression analysis. In total, 371 patients were investigated. 265 (71.4%) was categorized as PP group and 106 (28.5%) as NPP group. The mean age ($mean{\pm}SD$) was higher in the PP group ($52.4{\pm}9.8$) than in the NPP group ($49.5{\pm}11.9$) (p<0.05). Comparison of sleep parameters between the PP and the NPP group showed that the PP group had significantly lower BMI (PP: $26.1{\pm}3.2kg/m^2$; NPP: $27.8{\pm}4.3kg/m^2$, p<0.001), neck circumference (PP: $39.7{\pm}2.8cm$; NPP: $41.5{\pm}3.7cm$, p<0.001) and hypertension rate (PP: n=89/265 (33.5%); NPP: n=48/106 (45.2%), p=0.0240). In the PP group, the percentage of deep sleep (PP: $8.7{\pm}8.1%$; NPP: $5.6{\pm}7.0%$, P=0.001) and rapid eye movement (REM) (PP: $17.5{\pm}6.1%$; NPP: $14.0{\pm}6.9%$, p<0.001) were significantly higher whereas the percentage of light sleep (stage N1) was significantly lower than the NPP group (PP: $30.4{\pm}12.3$; NPP: $44.5{\pm}20.8%$, p<0.001). During the sleep, the AHI in the supine position (PP: $48.6{\pm}19.5$; NPP: $60.5{\pm}22.6$, p<0.001) and in the non-supine position (PP: $9.4{\pm}8.9$; NPP: $48.4{\pm}24.8$, p=<0.001) were significantly lower and the minimal arterial oxygen saturation in non-REM sleep was significantly higher in the PP group (PP: $80.3{\pm}7.6$; NPP: $75.1{\pm}9.9$, p=<0.001). There were no significant differences in all questionnaires including quality of life. The results of the binary logistic regression analysis showed that age, the amount of REM sleep(%) and AHI were significant predictive factors for positional OSA. The significant predictive factors for positional OSA were older age, higher percentage of REM and lower AHI. The questionnaire results were not significantly different between the two groups.

Accounting information system is the most important and formal subsystem of the total information system of an organization which produces and delivers financial information. An organization has its own contigent characteristics. It is the key to a successful development of accounting information system to select the development mode and information characteristics appropriate for the contigent characteristics. The main purpose of this study is to analyze the relationship between the contigent factors and the development mode of accounting information system. In addition, this study will examine the relationship between the contigent variables and the information characteristics of accounting information system. The research method adopted in this study is the survey. The results show that the environmental uncertainty, organization size, task diversity, task interrelatedness, and management commitment are positively related with the involvement and role of user in the system development process. The aggregate information regarding various departments tends to be produced by an organization under the uncertain environment. The information is reported periodically by a centralized organization. The aggregate information is preferred when tha task for implementation is diversified. The output information is more aggregate and provided more frequently when there exists a high interrelatioship between tasks. The output information is more external and reported more frequently in an organization with the high management commitment.

This study is intended to understand the architectural characteristics and trends of general hospitals in Europe. The Observations, interviewes with the staff, and analyses of related materials were executed through the study-visits of sample hospitals. Some results of the study could be summarized as follows : (1) The architectural characteristics of sample hospitals could be described as the realization of horizontal design concept, application of urban design method, specialization of service departments, intergration of facility design, and planning for the emergency & disaster. (2) The architectural trends of sample hospitals could be suggested as the decentralization of functions, promotion of building standard, enhancement of interior space, consideration of environment, and autonomous management & operation of facilities. (3) The humanistic and environmental approaches from european hospitals would be preferably applicable rather than the popular concept of automation, ultra-modernization and mega-structure in Korea. First of all, the bed-center and proper facilities for disaster should be considered.

Surface characterization of materials has been considered critical in the development of biomaterials, as many unfavorable responses from the body occur at the interface between a material and the body component. The contact angle measurement is one means to characterize the surface properties and to correlate them to the biocompatibility of materials. In this paper, surface characteristics of silk fibroin/S-carboxymethyl kerateine, representative fibrous proteins, were investigated by contact angle measurements of ESCA. The biocompatibility of the blends was evaluated based on minimal interfacial free energy concept, and compared with other potential biomaterials. It was also hypothesized that the enhanced surface polarity of the blends was generated from the conformational transition of proteins. This approach to evaluate the biocompatibility of materials based on surface characteristics may find wide utility in many biomedical applications.

The purpose of this study is to examine the factors influencing interdepartmental confilict in the military hospitals. Relatively little attention has been given to the conflict in the hospitals, especially within military hospitals. Delving into the realities of organizational conflict would provide us an insight of how to handle it. The questionnair survey was conducted for the 254 officers working in 8 military hospitals nationwide. The mean index score of interdepartmental conflict was 14 on the 5-25 point scale, indicating the conflict level was modest. Using t-test and ANOVA, we found that interdepartmental conflict was different by marital status of physicians or educational level of nurses. Next, we examined a causal model using multiple regression method. The personal characteristics of the respondents and the organizational characteristics - intradepartmental relation and interdepartmental relation - were included in the model as the independent variables. From the analysis, we found that working years at the organizations, type of work term, intradepartmental reliance or cooperation, interdepartmental redliance or resource management were significantly related to interdepartmental conflict. The effect from these variables, however, was different across three departments.

An infant's sleep varies considerably from that of adults in terms of structure, amount, and breathing pattern. After birth, sleep becomes evenly distributed throughout the day and night. Nighttime sleep gradually increases with the maturation of circadian rhythm, and sleep is gradually consolidated. Electroencephalography characteristics change with age, from early and dominant active (REM) sleep in newborns to increasing NREM sleep. Similar to other elements of growth, the upper respiratory tract and ribcage gradually increase in size with age, and respiratory control also improves. With these changes, sleep patterns also change. At this time that various sleep disorders may appear. Improved understanding of age-dependent changes in infant sleep can help determine the etiology and facilitate diagnosis of infant sleep diseases.
