Modern Museum has duplication which are non-profitability for public service and profitability for good service to visitors. Museum must have revenue source in order to provide a good service. It is necessary Museum do marketing for benefit Enterprise. In this Paper, we study empirical of Museum Marketing Activation which are introduced Quality Management. We prove four hypothesis which are (1)As professional manpower operation is high, Museum Performance result may rise, (2)Operation conformation is no impact in Museum management result, (3)If quality management operation are introduced, Museum Performance result may rise, (4)As there is much contents of Museum, Museum Performance result may rise.

Image quality and selection of optimized window for good quality reconstruction in coronary angiography using multi-detector row CT (MDCT) have not been studied by heart rate and its variation. Therefore, the effect of heart rate and its variation was systemically analyzed. Eighty-three patients were undergone contrast-enhanced coronary angiography using MDCT. In this study, sixty cases were enrolled. Two radiologists graded image quality as follows: 4, excellent; 3, good; 2, fair; l, bad. The starting points of the reconstruction window were chosen at seventy and forty percent of R wave interval. Optimized window was scored as 1 when 40% reconstruction was better quality than 70%, as 2 when 40% reconstruction is same as 70%, and as 3 when 70% reconstruction was better than 40%. Regression analysis was performed. The range of variation of beats per minute (BPM) was well correlated with image quality (r=-0.55, p=0.000), however correlation with optimized window percentage was not statistically significant (p=0.969). By contraries, median value of BPM was comparatively well correlated with optimized window grade (r=-0.24, p=0.086). Median value of BPM was not well correlated with image quality (r=0.l70, p=0.l97). Image quality is more affected by variation of heart rate (VHR) than by higher heart rate. Selection of optimized reconstruction window for good image quality is mainly affected by heart rate and there is a tendency that systolic phase reconstruction is better in image quality than diastolic reconstruction in higher heart rate.

This experiment was conducted to breed the Boxthorn varieties with resistance to Anthracnose, good quality and high yielding potential in 1984 to 1986(3 years).The character of "Yu seong 1" with resistance to Anthracnose and "Yu seong 2"with good quality and high yielding potential are fellows;1, The plant type of "Yu seong 1" was semi-elect type but became to electtype after 60C" rediation and yield was decreased because of the number of flowers.2. The yield of "Yu seong 2" was the highest of all varieties.3. The quality(Extract and Betain contents) of "Yu seong 2" was the best ofall varieties and visible character was good.The results of this experinent showed that "Yu seong 1" should be promisinglines in south area because of resistance Anthracnose and "Yu seong 2" should bepromising lines in north area.hracnose and "Yu seong 2" should bepromising lines in north area.orth area.

Osteoarthritis (OA) and rheumatoid arthritis (RA) are most popular types of arthritis in Korea. This study compared health-related quality of life (HRQoL) of homedwelling people with OA and RA in Korea. Data were drawn from the Korean nationwide representative survey. Subjects were 3,352 people with arthritis over 19 years of age (2,953 OA respondents and 399 RA respondents). Good HRQoL in OA respondents was dierentiated with limitation of mobility, perceived health status, age, economic status, presence of arthralgia, gender, medical coverage, and educational level. Good HRQoL in RA respondents was dierentiated with limitation of mobility, perceived health status, economic status, educational status, and presence of arthralgia. In conclusion, HRQoL and predictors of good HRQoL among people with arthritis diers for OA or RA. These results can be of use in development of health programs and clinical interventions for community-dwelling people with arthritis.

In this paper, we propose a packet scheduling algorithm for cellular relay networks by considering relay selection, variation of channel quality, and packet delay. In the networks, mobile users are equipped with not only cellular but also user relaying radio interfaces, where base station exploits adaptive high speed downlink channel. Our proposed algorithm selects a user with good cellular channel condition as a relay station for other users with bad cellular channel condition but can get access to relay link with good quality. This can achieve flexible packet scheduling by adjusting transmission rates of cellular link. Packets are scheduled for transmission depending on scheduling indexes which are calculated based on user's achieved transmission rate, packet utility, and proportional fairness of their throughput. The performance results obtained by using computer simulation show that the proposed scheduling algorithm is able to achieve high network capacity, low packet loss, and good fairness in terms of received throughput of mobile users.

In this paper, the implementation of dual rate ADPCM using G.723 16Kbps and 40Kbps speech codec algorithm is handled. For small signals, the low rate 16Kbps coding algorithm shows the same SNR as the high rate 40Kbps coding algorithm, while the low rate 16Kbps coding algorithm shows the lower SNR than the high rate 40Kbps coding algorithm for large signal. To obtain the good trade-off between the data rate and synthesized speech quality, we applied low rate 16Kbps for the small signal and high rate 40Kbps for the large signal. Various threshold values determining the rate are tested for good trade off data rate and speech quality. Also the low pass filter effect of speech input and output devices is simulated at several cut-off frequencies. To simulation result shows the good speech quality at a low rate comparing with 16Kbps & 40Kbps.

Client-supplier collaboration has been an imperative approach to new product development (NPD), in which a good product specification management system and practice is crucial to the assurance of product quality. This study investigates product specification management in client-supplier collaborative NPD. Based on the interviews and survey study, 12 problems and 13 good practices of product specification management are identified. It also compares the importance and degree of the implementation of the product specification practices in Hong Kong electronics industry. The results suggest that more intensive practices should be implemented for better product specification management.

본 연구에서는 회계정보의 질 대리변수로 회계이익-과세소득 차이 변동성을 활용하여 감사품질이 회계정보의 질에 미치는 영향을 검증하였다. 연구표본은 2010년부터 2014년까지의 유가증권 상장기업으로, 총 2,412 기업-연도이다. 본 연구의 분석결과는 다음과 같다. 분석결과, 감사품질을 회계이익-과세소득 차이 변동성과 음(-)의 관련성이 있는 것으로 나타났다. 이는 감사품질이 우수할수록 회계이익-과세소득 차이 변동성이 낮은 것으로, 감사품질이 우수할수록 회계정보의 질이 높음을 의미한다. 따라서 본 연구에 의하면 우수한 감사품질은 회계정보의 질 제고에 일정 부분 기여할 수 있을 것으로 기대된다. 본 연구는 급변하는 감사환경에서 감사품질에 대한 논란이 큰 이슈가 되는 현 시점에서, 수준 높은 외부감사의 효용을 제시함으로써 시의적절하며 외부감사가 자본시장의 파수꾼 역할을 하는 데에도 미약하나마 도움이 될 것으로 기대된다.

Purpose: The purpose of this study was to compare depression, somatoform disorders, and quality of life among older adults. Methods: Samples of 280 community-dwelling Korean older adults were included. The age range of the participants was 60 to 90 years (average $72.6{\pm}6.4$). The participants were assigned to one of two groups based on reported scores on the Pittsburgh Sleep Quality Index from September 2006 to March 2007. The two groups were designated as "poor sleepers"and "good sleepers". A T-test was used to compare depression, somatoform disorders and quality of life between the two groups. Results: Forty-six percent of participants reported scores that indicated they were poor sleepers. Poor sleepers reported significantly higher depression scores (p<.001), higher somatoform disorders scores (p<.001), lower for each SF-36 quality of life dimension, and lower mental and physical health summary scores (p<.001) than the reported scores of those participants who were classified as good sleepers. Conclusion: Older adults with poor sleep patterns are more likely to report higher depression, more somatoform disorders and a lower quality of life. Additional research is needed to identify the appropriate nursing interventions aimed at improving sleep quality, depression symptoms, somatoform disorders and the quality of life.

소프트웨어 제품의 품질을 높이는데는 소프트웨어 개발프로세스 중심과 제품 중심의 2가지 접근방법이 있다 CMM, ISO 9000 패밀리나 ISO/IEC 12207, SPICE 등이 프로세스의 인증을 통해서 소프트웨어 품질을 향상시키려는 시도라고 할 수 있다. 그렇지만 ‘좋은’ 프로세스만으로는 ‘좋은’ 제품의 품질을 보장하기가 어렵다. 최근 독립적인 제3자에 의한 소프트웨어 제품의 품질을 평가하기 위한 필요가 점점 증가하고 있다. 본 연구에서는 소프트웨어 제품의 품질을 평가하는데 SQC 기법을 응용하여 평가프로세스의 효율을 기하고 평가결과의 객관성을 확보하는 방안을 다룬다. 랜덤추출법에 의한 테스트 케이스를 선정하는 방법을 소개하고 소프트웨어 제품의 품질에 대한 적합성 기준을 선정하는 방안을 제시한다.
