  • This study is for the purpose of understanding User Satisfaction of Accounting Information System more closely by means of perceiving relations between Internal Controls and Quality. That is, this study is to assess Internal Controls and Quality and to connect those with User Satisfaction. This thesis is for the substantial study on whether Information Quality, System Quality, and Service Quality influenced by Internal Controls of Accounting Information System have an effect on User Satisfaction, when Internal Controls of Accounting Information System is good, The following hypothesis was made to achieve this purpose. First, Internal Controls will have an positive influence on Quality. Second, Qualify will positively affect User Satisfaction. Third, Internal Controls will positively Influence User Satisfaction. Fourth, Internal Controls will have a positive effect on User Satisfaction through Quality For the survey sample, this study gathered data on someone engaged in companies or organizations which have computer offices, and groups were differentiated between general staff and someone in charge of the computer office, and each group had different questions. In general, 622 of questions were distributed and 200 of the final valid samples were used for the substantial analysis. As the result of the study, the relations between Internal Controls and Quality are statistically significant. The relations between Quality and User Satisfaction ire also statistically significant. But the relations between Internal Controls and User Satisfaction are not statistically significant. Path Analysis was implemented to analyze the hypothesis on whether Internal Controls have an influence on User Satisfaction through Quality. When the result of analysis with Lisrel 8.5 was examined, index numbers(GFI, AGFI, RMR) representing the suitability of the model were enough to be taken and it is showed that there is the suitability of the model. Internal Controls of Accounting Information System can't have an influence on User Satisfaction with Quality. As the above hypothesis was rejected, Through Path Analysis, this study examined the influence which relations between Internal Controls and Quality, factors of User Satisfaction, have on User Satisfaction, and is very meaningful in terms of the first trial. And on the point of time when there are little studies on the effect analyses between Internal Controls and Quality, this study would be the promoter for the future. The limitation on this study is to analyze only mutual effects between factors by choosing Internal Controls, Quality, and User Satisfaction as survey variables. The study which measure items with precision which are related to each variable and understand measurement factors clearly should be implemented.

  • In existing mobile computing environments, users need to choose between their privacy and the services that they can receive from an application. However, existing mobile platforms do not allow users to perform such trade-offs in a fine-grained manner. In this study, we investigate whether users can effectively make utility-privacy trade-offs when they are provided with a multilevel privacy control method that allows them to recognize the different quality of service that they will receive from an application by limiting the disclosure of their private information in multiple levels. We designed a research model to observe users' utility-privacy trade-offs in accordance with the privacy control methods and other factors such as the trustworthiness of an application, quality level of private information, and users' privacy preferences. We conducted a user survey with 516 participants and found that, compared with the existing binary privacy controls, both the service utility and the privacy protection levels were significantly increased when the users used the multilevel privacy control method.

  • Objectives: Despite treatment, the pre-traumatic facial appearance of patients with maxillofacial fractures might not be able to be restored, and this difference can affect the person's quality of life (QoL). This study was designed to evaluate changes in QoL of people with maxillofacial fractures. Materials and Methods: The study population was comprised of participants with maxillofacial fracture and age- and sex-matched healthy controls without history of such fracture. QoL was measured using the World Health Organization Quality of Life BREF (WHOQOL-BREF) questionnaire, which was administered to the patients before treatment (Time 1), at 6 weeks post-treatment (Time 2), and at 12 weeks postoperatively (Time 3). The values were compared with those of healthy controls. The QoL was compared between closed reduction group and open reduction and internal fixation group. Results: The QoL scores of people with maxillofacial fracture before treatment were significantly lower (P=0.001) than those of healthy controls in all domains of the WHOQOL-BREF. The QoL scores in the psychological and social domains of patients with maxillofacial fracture at Time 3 were still lower than those of healthy controls (P=0.001). Conclusion: The QoL of patients with maxillofacial fracture was significantly reduced before treatment in all domains and remained reduced in both psychological and social domains weeks after treatment. Therefore, clinicians must be aware of and manage the residual psychosocial issues that can accompany the post-treatment period of maxillofacial injury.

  • 본 연구는 셀레늄(Se) 처리가 '원황' 배 과실품질에 미치는 영향을 구명하고자 실시하였다. 과실의 색상과 과형은 처리 간에 차이가 없었다. 모든 Se처리는 과실 내 칼륨과 Se함량을 높였으며, 과실의 단맛을 높이고 신맛을 줄이는 결과를 나타냈다. 저온 저장 시 과실의 경도를 조사한 결과, 모든 Se 처리구에서 대조구보다 높은 과실경도를 유지했다. 또한 Se 처리구에서, 높은 과실 비중과 과육 내 치밀한 세포 조밀도를 나타내서, 배 과일의 상품성을 저하시키는 바람들이 현상을 감소시켰다. 전체적으로 Se 처리방법에 따른 과실품질의 유의적인 차이는 크지 않았으나, Se 엽면 살포구에서 보다 더 나은 상품성 과실을 생산할 수 있는 토대를 마련하였다.

  • The development of paper machines, increasing machine speeds with new, mostly low basis weight and/or high ash content paper grades, as well as the fact that several trends regarding process items have increased the sensitivity of papermaking. At the same time, papermakers are looking for flexibility in the production line. We can say that with all PMs the biggest benefits with the lowest capital spending can be achieved by focusing on improved wet end management. In order to manage wet end chemistry on a paper machine, our goal is to control sub-process through which we can influence the operation of the entire wet end with maximum effect. Key measurements and controls are-white water consistency control which is the most effective way to control retention - charge demand measurement and control which takes care of concentration of the anionic material entering to PM -ash measurements and controls which are deeply related to retention and paper quality This paper presents and concentrates to two of these key controls ; retention and charge. The purpose of charge control is to give the process control the tools to react to changes caused by amount of dissolved and colloida material incoming to wet end system. It is called coagulation or fixing control. Retention control is then taking care of retention aid flow to the process by responding any changes seen in white water consistency. It is called flocculation control. Each of these solutions separately , and even more effectively all together, stabilize the wet end operations and so greatly improve the produced paper quality and machine runnability. Practical results will be presented and they are referring to the latest mill cases. We have developed the first wet end measuring system in the late 1980s and control solutions based on this modern measuring technology were completely updated in 1990s. This paper introduces the principle, operation , and results of our unique wet end analyzers (retention and charge ) which are at the level of automation solutions as a part of paper machine quality control Especially our newest member of the platform , on-line charge analyzer has reached and set new standards to the on-line charge monitoring.

  • This paper presents quality and measure controls of Plastic Board Drains(PBD) for improvement of soft ground. Laboratory and field tests has been carried out to evaluate the quality of PBD focussing on : discharge capacity of flow area; permeability of filter sleeve; migration of fine particles; deformed shape of PBD; consolidation of clay in the close vicinity of PBD; tensile strength of PBD; long-term consolidation behavior of clay-PBD. Test results show that the quality of PBD is sufficient to perform the improvement of soft silty and clayey ground. But, geotechnical engineer must make efforts minimizings of PBD damage and ground disturbance, continuity of drainage system during construction. Adequate monitoring system should apply at ground focussing on number, location, and accuracy of geotechnical instrumentation, measurement and evaluation of data for ground behaviour.
