Objectives The aim of this study was to report the improvement of delirium and performance status in the small-cell lung cancer patient who had multiple brain metastases and pericardial effusion after Sasang constitutional treatment. Methods We retrospectively reviewed the medical records, medical laboratory and image scans of 71-year-old male patient diagnosed as small-cell lung cancer. Results The small-cell lung cancer with multiple brain metastases patient sometimes talked deliriously even after the whole brain radiation therapy. During the hospitalization period, he showed delirium. We treated him with Gihwangbaekho-tang and Dojeokgangki-tang as a main therapy. After treatment, he didn't show delirium and performance status was improved. Conclusions A small-cell lung cancer with multiple brain metastases patient showed the improvement of symptoms (delirium, poor performance status, constipation and poor oral intake) with the treatment of Gihwangbaekho-tang, Yanggyuksanhwa-tang and Dojeokgangki-tang.

Purpose: This study was to investigate the needs for developing a health promotion program for the elderly, and to compare the health promoting behaviors and perceived health status between high and low income elderly. Method: The data were collected from 80 high) income elderly and 84 low income elderly through face to face interviews. The instruments used in) this study were the Health Promoting Lifestyle Profile II (HPLP II) and Perceived Health Status. Results: 1) The total score of the HPLP for the elderly was 2.29. In the subscales, the highest degree of performance' nutrition', following 'stress management', 'spiritual growth' and 'health responsibility' and the lowest degree of performance was 'physical activity'. 2) The high income level elderly had significantly higher total HPLP scores than the low income level elderly. The biggest difference was found in 'physical activity' between high) and low) income elderly. 3) The mean score of perceived health status was 8.21. The high) income elderly had significantly higher perceived health status than the low income elderly. Conclusion: The above findings indicate that it is necessary to develop a health promotion program with reinforced physical activity, health responsibility for the elderly in Korea.

Purpose: In this paper, we investigate whether the endeavors for Six Sigma quality management by a firm have positive effects on its financial performance and the length of Six Sigma implemented period affects its financial status. We find a relationship between Six Sigma implemented period and several financial performance index using a smoothing spline function. Methods: A smoothing spline function is used in order to analyze the relationship between efforts for quality management and financial performance. Specifically, the return on assets, return on equity, sales cost and business fee are investigated as dependent variables and the efforts for quality management as independent variable. Results: As a result of the analysis, the indication is that companies that put effects into the Six Sigma quality management have a positive result in its financial status. In detail, the efforts for Six Sigma quality management have positive effects on total asset turnover ratio and Six Sigma implemented period on net income to net sales ratio. Additionally, companies with longer (shorter) period of Six Sigma program have more (less) improvement in its financial status. Conclusion: It can be concluded that the company's efforts for quality management positively influence financial performance.

본 연구의 주된 목적은 노사관계관리의 관점에서 노사관계의 질이 직무태도와 직무성과에 미치는 영향을 규명하기 위한 것이다. 구체적으로는 노사관계의 질이 종업원의 조직몰입과 이직의도 그리고 직무성과에 미치는 영향, 노조원 여부의 조절효과를 확인하기 위한 것이다. 연구결과 노사관계의 질은 조직몰입에정(+)의 영향을, 이직의도에는 부(-)의 영향을 그리고 직무성과에는 정(+)의 영향을 미치는 것으로 확인되었으나, 노조원 여부의 조절효과는 발견되지 않았다. 그리고 이러한 연구결과를 토대로 효과적인 노사관계관리에 필요한 전략적 시사점을 제시하였다.

Purpose: This study was conducted to examine psychological empowerment and awareness and performance of Healthcare-Associated Infections(HAIs) control among Intensive Care Unit (ICU) nurses. Method: The data for this study were collected using structured questionnaires from 178 nurses working in the ICUs of four hospitals with more than 500 beds. Results: The subjects'psychological empowerment, awareness and performance of HAIs control were mean over. The subjects'psychological empowerment showed statistically significant differences depending on age, marital status, academic background, clinical career, ICU career, and position and experience in infection control among their general characteristics. Awareness of HAIs control showed statistically significant differences depending on age, gender, marital status, clinical career, and ICU career. Performance showed statistically significant differences depending on age, gender, marital status, and, ICU career. Regarding the subjects' performance of HAIs control, there was a statistically significant positive correlation between psychological empowerment and awareness. Conclusion: It was found that it is necessary to strengthen differential customized training according to the subjects'characteristics for effective HAIs control, and to strengthen the nurses'awareness of HAIs control through systematic evaluation, monitoring, and feedback, as well as continuous education and training.

The neural network method has been introduced to design a controller for linear motor feed system and system operation status was monitored. It is most difficult to achieve controller gain tuning because of the information limit. Regardless of the system structure, conventional control gain could be adjusted minimizing the resulting error for both position and velocity using the proposed method. Slight performance deterioration was observed at the small value of training epoch. Different controller performance for position was observed with respect changed sampling time. Actuated system performance was monitored using neural network signal processing and operational status was predicted with the rate of 80% approximately.

Multipath TCP (MPTCP)는 다중 경로를 통해 데이터를 전송하므로 향상된 네트워크 성능을 기대할 수 있으나, 예고 없이 전송 경로에서 발생되는 Bufferbloat은 해당 경로의 성능뿐만 아니라 다른 경로의 성능 역시 저하시켜 단일 TCP 보다 오히려 좋지 않은 성능이 발생한다. 이와 같은 Bufferbloat 문제를 해결하기 위해 본 논문에서는 송신단에서 MPTCP 레벨의 전송 상태 모니터링 방법과 HoL 패킷 재전송 알고리즘을 제안하였다. 제안한 알고리즘은 송신단 독자적으로 Bufferbloat 감지를 가능하게 하며, 전송 상태 모니터링 버퍼에서 HoL 패킷을 식별하여 정상 경로로 재전송함으로 HoL Blocking문제를 해결할 수 있도록 하였다. NS-3기반 시뮬레이션 결과 제안한 알고리즘은 기존 MPTCP 대비 전송 성능은 최대 22.8%까지 향상되었고, 송신 버퍼 및 수신 버퍼에 대기하는 평균 패킷 수는 기존 대비 각각 44.3%와 9.2% 수준으로 감소되었음을 확인하였다.
