  • Quality of Life in Pakistan is an understudied and rather unexplored domain. With various definitions and challenges to explaining quality of life, a public opinion poll and scientific surveys have been conducted in order to find out more about the quality of life in Pakistan. Using a nationally representative sample, this paper seeks to identify quality of life measures, find results, and analyze them to see what they mean, specifically in the context of Pakistan.

  • 본 연구에서는 어묵의 유통기한을 소비기한으로 변경하기 위해 품질평가를 진행하였다. 제품 품질 평가를 위해 보관 조건은 5, 10, 15 ℃로 설정하고 pH, 산가, 휘발성염기질소, 세균수, 대장균군 등 5가지 항목에 대한 실험을 진행하였다. 실험결과 어묵의 품질유지한계기간은 5 ℃에서 43일, 10 ℃에서 30일, 15 ℃에서 7일이었다. 품질평가에 사용된 5가지 시험항목 중 품질한계지표가 있는 항목은 산가, 세균수, 대장균군이었다. 그리고 3가지 보관조건에서 품질유지한계기간을 결정하는 지표는 세균수였다. 본 실험에 사용된 어묵의 유통기한은 10일이나 품질평가를 통해 10 ℃에서의 소비기한은 28.5일로, 품질유지한계기간인 30일에 안전계수 0.95를 곱한 값이다. 그러나 본 연구는 1개 업체의 어묵 1품목에 대한 품질평가를 수행하였기에, 본 연구에서 설정한 품질유지한계기간 및 소비기한을 보편적으로 사용하기에는 무리가 있다. 유통기한을 소비기한으로 변경하기 위해서는 다양한 제품에 대한 광범위한 품질 연구가 필요하다. 이 제도가 잘 갖춰진다면 올바른 음식물 섭취를 통해 음식물폐기물을 줄이는 데 도움이 될 수 있고, 소비자들은 안심하고 식품을 섭취할 수 있다.

  • Purpose: The purpose of this study was to investigate the level of clinical image quality of panoramic radiographs and to analyze the parameters that influence the overall image quality. Materials and Methods: Korean dental clinics were asked to provide three randomly selected panoramic radiographs. An oral and maxillofacial radiology specialist evaluated those images using our self-developed Clinical Image Quality Evaluation Chart. Three evaluators classified the overall image quality of the panoramic radiographs and evaluated the causes of imaging errors. Results: A total of 297 panoramic radiographs were collected from 99 dental hospitals and clinics. The mean of the scores according to the Clinical Image Quality Evaluation Chart was 79.9. In the classification of the overall image quality, 17 images were deemed 'optimal for obtaining diagnostic information,' 153 were 'adequate for diagnosis,' 109 were 'poor but diagnosable,' and nine were 'unrecognizable and too poor for diagnosis'. The results of the analysis of the causes of the errors in all the images are as follows: 139 errors in the positioning, 135 in the processing, 50 from the radiographic unit, and 13 due to anatomic abnormality. Conclusion: Panoramic radiographs taken at local dental clinics generally have a normal or higher-level image quality. Principal factors affecting image quality were positioning of the patient and image density, sharpness, and contrast. Therefore, when images are taken, the patient position should be adjusted with great care. Also, standardizing objective criteria of image density, sharpness, and contrast is required to evaluate image quality effectively.

  • A various quality data are produced during nuclear fuel fabrication. In order to control quality data efficiently, Computerization of Quality Information System(QIS) using personal computer was established. Database control software and analysis software were developed for QIS. QIS was applied the fuel manufacturing and quality inspection. Quality trend analysis, process control, process capability and quality history docket for nuclear fuel manufacturing were performed by QIS. Through the Quality Information System, quality assurance, quality control, process control and manufacturing engineering were performed efficiently in nuclear fuel manufacturing.

  • Purpose: This is a descriptive research to examine the level of health status, depression, and quality of life in the elderly, the relations among the factors. Methods: Subjects were 441 elders in Seoul and Gyung-gi province. Data were collected from July 10, 2006 to October 30, 2006. Measures were CMI, GDS, and SF-36. Data were analyzed by descriptive statistics, Pearson correlation coefficient, T-test, and ANOVA. Results: (1) The health status was the average of 1.75, which indicates being good. Depression was the average of 2.85, which indicate being high, and the quality of life was the average of 2.72, which indicate being moderately. (2) The relations indicate that the better status of health is related with the lower depression, and the better status of health is related with the higher quality of life, and the higher depression is related with the lower quality of life. (3) The health status, depression, and quality of life all showed significant differences according to age, education, past occupation, current occupation, dwelling pattern, monthly pocket money, living expense. Conclusion: for nursing intervention strategies, it are requested the special attention of the current occupation level and interpersonal relation ship in older people.

  • The underground living spaces have become one of the major environment of this decade in urban area. This study was carried out to examine contamination level for purpose of preservation of the pleasant underground environment. Three subway stations and three underground shopping centers in Seoul and two underground shopping centers in Busan were selected and surveyed by measuring gaseous pollutants $(SO_2,\; NO_2,\;CO,\;HC,\; HCHO,\;CO_2)$, dust, airborne microbes, and the other air condtions (temperature, humidity, air pressure, air flow, kata cooling power). These examined data were compared with four kinds of standard (building sanitation management, room air quality standards, occupational safety and health standards, ventilation equipment) as environmental hygiene.

  • Purpose - The purpose of this study was to explore the relationship between C2C logistics service quality(convenience, responsiveness, reliability, information and empathy) customer satisfaction and customer loyalty. Design/methodology/approach - This study collected 252 survey data from consumers who use C2C platform in China. Then using SPSS 24.0 in order to analyze the data. This study used SPSS 24.0 to perform empirical analysis with 252 people who use C2C platform in China. Findings - First, it was confirmed that the quality of logistics service(convenience, responsiveness, reliability, information and empathy) had a positive effect on customer satisfaction. Second, logistics service quality(convenience, responsiveness, reliability, information and empathy) positively affects the customer loyalty. Third, there is also a strong relationship between customer satisfaction and customer loyalty. Research implications or Originality - It is well known that logistics is an important part of e-commerce. Research on the influence of B2B logistics service quality on customer satisfaction and customer loyalty is more currently, but research on C2C is relatively less. Our study contributes the related research area by doing empirical analysis of the relationship between the logistics service quality and customer satisfaction and customer loyalty to provide development suggestions for C2C sellers.

  • A watershed model was constructed using Hydrological Simulation Program Fortran to quantitatively predict the stream flows at major tributaries of Nakdong River basin, Korea. The entire basin was divided into 32 segments to effectively account for spatial variations in meteorological data and land segment parameter values of each tributary. The model was calibrated at ten tributaries including main stream of the river for a three-year period (2008 to 2010). The deviation values (Dv) of runoff volumes for operational stream flow forecasting for a six month period (2012.1.2 to 2012.6.29) at the ten tributaries ranged from -38.1 to 23.6%, which is on average 7.8% higher than those of runoff volumes for model calibration (-12.5 to 8.2%). The increased prediction errors were mainly from the uncertainties of numerical weather prediction modeling; nevertheless the stream flow forecasting results presented in this study were in a good agreement with the measured data.

  • In order to study the general characteristics of reservoir and stream sediments, various analysis tests were conducted. Water contents and ignition loss were measured to know the primary sediment characteristics. The COD, total phosphorus and nitrogen were contained for the determination of organic substance content. For the purpose of establishing the contamination degree of heavy metals, some heavy metal contents were investigated. In heavy metal contents, reservoir sediments showed somewhat higer value than stream sediments. As a result, the reservoir sediment content of all analysis items were higher than stream sediment.
