As the competition between countries has become higher and the notion of software quality has been widely spread. it has been necessary to develop technologies that can ensure and produce high quality software. With the advent of information-oriented society. quality control has to transfer to the quality control activities focused on software system instead of those activities focused on hardware system. If so, how do we get to handle the quality control on the basis of the new approach. Also, as software applications have grown. so too has the importance of software quality. In order to manage software quality, the technology to specify and evaluate both the software product quality and development process quality objectively quantitatively is most important. To produce products of good quality, we need a more progressive quality control system according to the need of software development life cycle. In other words, we do software right the first time or build quality in the process. On the basis intermediate and final time or build quality in the process. On the basis of data achieved, we can evaluate the products according to the consequences of the data, What are the problems to contrive the software quality control system?, we con promote the quality of products. To achieved that goal, we con provide a suitable the technique and method of software quality control.

Taguchi methods have been used for a long time to improve the product quality and process performance of a manufacturing system, Few researchers have applied this methodology in laser beam cutting (LBC) of sheet metals and found the considerable improvement in cut qualities. In all experimental investigations of LBC so far, the objective was to optimize the single quality characteristic at a time. In this paper the simultaneous optimization of multiple quality characteristics such as Kerf width and material removal rate (MRR) during pulsed Nd:YAG LBC of thin sheet of magnetic material (high Silicon-steel) has been presented using Taguchi's quality loss function. The results show the considerable improvement in multiple S/N ratio as compared to initial cutting condition. Also, the comparison of results from single and multi-objective optimization have been presented and it was found that the loss in quality is always possible shifting from single quality to multiple quality optimization.

Purpose : the management of University Hospital is being challenged in maintenance of reasonable level of income and high ranked reputation by domestic competition with each other and emergence of enterprised owned hospitals. It is imperative that University Hospitals have to make management for patient satisfaction. Furthermore, increased patient's requirement for qualified hospital services (quality assurance) and low-estimated service fee also repress the hospital management condition as well as medical markets open following with Urguay Connection. Due to these unforable conditions surrounding hospital management, -University Hospitals are being pressed to seek improved management strategies. To develope the strategies, we need to have basic understanding about the problems on hospital management and detail information for various patient's requirement. Methods: For this study, we have analysed out-patients from five different University Hospitals located in Seoul, Korea. To obtain the data, we have carried out personal interviews with patients who patients who visit the Out-Patient Clinics of five different University Hospitals using a previously prepared questionnaire. Result: Around 65.7 percent of the visits to University Hospitals were indwelt in the vicinity of 1 hour and motuvation of visiting University Hospital was expending high wuality medical csre in 49.3 percent. The 79.3 percent of the patients have experienced inconvenience during medical care in University Hospital. The most inconvenient condition was waiting for doctors. The 57.2 percent of total patient have experienced rudness. The most rudness condition was registration and receipt desk in 44.4 percent. Patient expect that doctors working in University Hospitals as professors have high and updated medical knowledge(50.4%) and University Hospitals have a high quality medical care system(79.4%). The patient satisfaction was relatively low in 61.1 percent of total patient and revealed high frequency of again visit University Hospital in satisfaction group. Comparison of interhospital analytical study showed quite difference on various problems. Conclusion: Almost patients who visit to Out-Patient Clinic of University Hospital havevisiting motivation to high quality medical care. University Hospitals have several different unsatisfactorial factors and revealed different degree of patient satisfaction.

This study was carried out to provide the geographic information based on the distribution of rice qualities and palatability in Gyeoungbuk province of Korea. The rice grain quality and environmental factors were analyzed using 513 sampling sites based on different five-agroclimtic regions of Gyeoungbuk province during three years from 2002 to 2004. In rice grain quality characteristics, the average palatability was low in South eastern coastal and Tabaek semi alpine regions as $67.6\~68.3$ and the coefficient of variation (CV) was relatively high as $6.2\~7.4\%$. The average head rice rates were low in South and Central eastern coastal regions as $87.3\~88.2\%$ and CV was high as $8.2\~8.3\%$. The average protein content was high in Central eastern coastal regions as $8.0\%$ and CV was high as $8.2\~8.3\%$. In case of palatability, the variation was differed clearly between high and low agroclimatic regions; it means that it is possible to divide the same agroclimatic region of high CV into two or three areas by CV of palatability. As the results of subdividing each existing agroclimatic regions based on the palatability, the variation of grain quality characteristics was become lower than that of existing five-agroclimatic regions. Therefore, the re-establishing of agroclimatic region based on rice grain quality was very important for precise cultivation for rice.

This experiment was carried out to examine ecological response and soybean quality as affected by environmental cultivation for producing high seed quality in domestic soybean variety. The results are as follows: Under equal cumulative temperature condition, soybean plants grown in Muju showed longer days to flowering, which was an effect of the long day-length on high latitudes, and longer duration of reproductive stage as a result of low temperature within that period. Considering apparent seed quality, 100 seed weight of soybeans grown in Muju was heavier than Miryang. Ratio of seed crack and disease-damaged seeds was lower in Muju, and these parameters decreases as planting was delayed. The protein contents did not show significant difference in terms of altitude and planting date, however, crude oil contents were higher in Miryang. An opposite trend was observed in C18:1 and C18:3. In the fatty acid composition, the proportion of C18:1 decreased as seeding date was delayed, and was higher in Miryang. Opposite observations were obtained from C18:3. The anthocyanin contents were highest on June 10 planting and higher in Muju than in Miryang. Isoflavone content was higher as seeding date was delayed and is similar accross seeding dates in Muju. As a summary, for high seed quality production the optimum planting date was June 10, and Muju was more suitable region than Miryang.
