Business survey index(BSI) is an economic forecasting index made on the basis of the past achievement of the company and enterpriser's plan and decision for the future. Even the index is very popular in economic situations, only a little research result is known to the public. In the paper we investigate statistical properties of BSI. We define population BSI in the finite population and estimate it unbiasedly. Also we derive the variance of the estimated BSI and its unbiased estimator. In addition, confidence interval of the estimated BSI is proposed. We asserte that confidence interval of the estimated BSI is more reasonable than the relative standard error.

The purpose of this study was to identify the effects of bed baths with 2% chlorhexidine on the incidence of Methicillin-resistant Staphylococcus aureus (MRSA) and blood stream infection (BSI) and to suggest guidelines on the therapeutic bed baths using skin cleaner. This study was designed to compare the incidence of MRSA and BSI of the experimental group(n=188) who received the bed baths with 2% chlorhexidine with the incidence of MRSA and BSI of the control group(n=199) who received the existing bed baths with soap and skin cleaner. A research design used in the study was a randomized control group posttest-only design. The experimental group had 6.7% decrease in MRSA acquisition than the control group (7.4% vs 14.1%, p=.036). The experimental group was decreased in the incidence density of MRSA than the control group (9.32 cases per 1,000 patient-days at risk of experimental group vs 15.44 cases per 1,000 patient-days at risk of control group; p=.099). The experimental group had 4.5% decrease in the rate of BSI than the control group (0.5% vs 5.0%, p=.011). The experimental group was decreased in the incidence density of BSI than the control group (0.67 cases per 1,000 patient-days at risk of experimental group vs 5.52 cases per 1,000 patient-days at risk of control group; p=.052). These finding indicated that bed baths with 2% chlorhexidine is an effective nursing intervention to decrease the incidence of MRSA and BSI.

Background: Continuous surveillance of pattern of blood stream infection is necessary in febrile neutropenia (FN)especially with the recent escalating trend in the management of pediatric cancer patients towards intensified regimens and with the increase in infections caused by resistant organisms limiting the choice of antibiotics. Aim: To monitor change in pattern of blood stream infections (BSI) in FN pediatric cancer patients. Materials and Methods: Surveillance of FN episodes with positive BSI was prospectively monitored and compared to a previous surveillance in the same pediatric oncology unit. Results: A total of 232 BSI positive episodes were documented in 192 patients during a 6 months period. The results of recent surveillance analysis showed an increase in intensified regimens of chemotherapy, antimicrobial resistance, fungal infections, and prolonged duration of episodes when compared to previous surveillance, with p value sof <0.001, 0.005, 0.021, and <0.001, respectively. There was an apparent decrease in the crude mortality but this was not statistically significant, to 6% in 2011 from 10 % in 2006. Conclusions: The pattern of BSI at our institution is still inclining towards gram positive organisms but is showing a shift towards more antibiotic resistance and fungal infections.

Background: The aims of this study were to determine the extent of workplace bullying perceptions among the employees of a Faculty of Medicine, evaluating the variables considered to be associated, and determining the effect of workplace bullying perceptions on their psychological symptoms evaluated by the Brief Symptom Inventory (BSI). Methods: This cross-sectional study was performed involving 355 (88.75%) employees. Results: Levels of perceived workplace bullying were found to increase with the increasing scores for BSI and BSI sub-dimensions of anxiety, depression, negative self, somatization, and hostility (all p < 0.001). One point increase in the workplace bullying perception score was associated with a 0.47 point increase in psychological symptoms evaluated by BSI. Moreover, the workplace bullying perception scores were most strongly affected by the scores of anxiety, negative self, depression, hostility, and somatization (all p < 0.05). Conclusion: The present results revealed that young individuals, divorced individuals, faculty members, and individuals with a chronic disease had the greatest workplace bullying perceptions with our study population. Additionally, the BSI, anxiety, depression, negative self, somatization, and hostility scores of the individuals with high levels of workplace bullying perceptions were also high.

In this paper we proposed a modified reliability function for improving bimodal speaker identification(BSI) performance. The convectional reliability function, used by N. Fox[1], is extended by introducing an optimization factor. We evaluated the proposed method in BSI domain. A BSI system was implemented based on GMM and it was tested using VidTIMIT database. Through speaker identification experiments we verified the usefulness of our proposed method. The experiments showed the improved performance, i.e., the reduction of error rate by 39%.

2006년 3/4분기 현재 국내 300만 사업체 중 70만개 업체가 ASP 서비스를 이용하며, ASP 서비스를 제공하는 사업체 수는 159개 인 것으로 조사되었다. 국내 159개 ASP 서비스 제공업체를 대상으로 BSI를 조사해 본 결과 실적치는 고객 수(108.5)보다 매출액(106.6), 매출액보다는 경상이익(98.1)에 대한 경기를 보다 어둡게 보는 것으로 나타났다. 따라서 BSI를 통해 본 ASP산업은 외형적으로는 국내 70만개라는 사업체가 ASP를 통해 각종 IT솔루션을 이용하고 있는 반면에 ASP 서비스를 제공하는 ASP 제공업체의 경영 채산성은 상대적으로 열악함을 의미하고 있다. 따라서 향후 외국 대형 소프트웨어 유통업체들의 국내 진입 선언 등과 더불어 국내 ASP 제공업체들의 대응 전략 마련이 절실히 필요로 하는 때임을 암시하고 있다.

설문조사방식인 기업경기조사는 간편하고 신속하게 경기를 파악할 수 있을 뿐만 아니라 전통적인 경제통계로는 포착하기 어려운 기업의 경제활동에 대한 평가와 전망을 지수화할 수 있다는 이점이 있다. 본고에서는 전국경제인연합회의 전망BSI를 이용하여 다음 분기 경제성장률을 예측하는 데 도움이 되는지 살펴보았다. 예측력 검정 결과 전망BSI는 1${\sim}$2분기 이후의 경제성장률과 높은 상관관계를 보이고 있으나 기간에 따라서는 오히려 예측오차를 크게 할 수도 있는 것으로 나타났다. 우리나라를 포함하여 각국에서 서베이 자료의 활용도가 점차 커지고 있는 만큼 조사방식 개선, 합성지수 개발 등 기업경기조사의 정확도 제고를 위해 많은 노력을 기울일 필요가 있다.

본 연구는 선행연구들과 달리 경제변수로 설명할 수 없는 경제주체들의 심리적 요소가 주가에 영향을 미칠 수 있다는 관점에서 주가와 거시경제변수 및 경제주체들의 기대심리간의 장기 균형 및 동학구조관계를 분석한다. 주가는 기업의 내재가치를 나타내며 이는 상당부분 현재와 미래의 경제상황에 의해 영향을 받을 것이다. 미래경제상황을 정확히 예측할 수는 없으나 경제 주체들은 미래경제상황을 예측하게 되며 그 예측은 주가에 반영될 수 있다. 검증결과 BSI 전망치와 같은 경제주체들의 기대심리가 주가결정에 가장 중요한 단일 변수인 것으로 나타났다. 이변량 공적분검증을 실시한 결과 실질주가지수는 BSI와 장기균형관계에 있는 반면 다른 거시경제변수와는 공적분관계에 있지 않은 것으로 나타났다. 다변량 공적분분석에서도 BSI가 포함된 경우에만 KOSPI/P와 장기균형관계에 있는 것으로 나타났다. 벡터오차수정모형으로 동태적 관계를 분석한 결과, 이변량과 다변량 분석 모두에서 이들 두 변수의 오차수정항이 통계적으로 유의하여 장기균형으로부터 이탈에 대하여 상호 조정하는 것으로 나타났다.
