The purpose of this study is to construct an Environment Database Management System (EDMS) for the Saemangeum watershed based on the linkage of Water Quality Model, i.e. QUALKO and WASP model, and GIS database to estimate water quality effectively in this area. There are two major river systems on this study area, the Mangyeong and the Dongjin rivers. Input data are automatically generated through the calculation of the pollutant loading and inflow concentration from the point and non-point sources. The developed system is composed of three different phases, such as pre-process, model performance and post-process. The Model performance is supported by the database at pre-process phase and model performance results were shown in the graphs and attribution data at post-process phase. The measured data from the Mangyeong and the Dongjin rivers are used to evaluate the applicability of EDMS. The EDMS shows higher reliability, and it is expected to contribute to the effective management and improvement of water quality modeling in the Saemangeum watershed since the system reduces complications of using a model in DOS operating environment and increases the accuracy of water quality analysis.

This study examined effect of preceptorship on clinical education of 39 senior nursing students. Competency scores and satisfaction with preceptors scores were investigated. Competency scores of the students before the clinical education (pre-competency scores) were compared with the competency scores after the clinical education (post-competency scores), and satisfactory scores were also examined after the clinical education. Study results showed that the total post-competency scores were increased compared to the total pre-competency scores, and this increment was statistically significant. However, analyzing sub-domains of the competency scores indicated only the nursing-skill domain scores were increased while the scores of interpersonal domain and management domain were increased but statistically insignificant. Satisfaction with preceptors scores were also more than the average scores reflecting the students were satisfied with their preceptors generally. The students, However, grade low in the preceptors' intellectual ability while their professional and interpersonal ability were rather satisfied. This study indicated preceptors should make more efforts to teach interpersonal and management skill and increase their intellectual ability. This study recommended a systematic reward system for the preceptors to increase the motivation to teach students is needed.

The purpose of this study was presented basic data for management of living kidney donor to make bioethical decision. The research subjects were the documents and progress notes of Doctor's and Nurses in medical records related to kidney donation and nephrectomy of 20 kidney donors who received nephretomy at 4 general hospitals in Pusan. The result of this study, a desirable documents to help the living kidney donor might include following : 1st, identification of the donor and the guardian. 2nd, confirmation of the intension of kidney donor which is based on humanity or not and 3rd, a written oath about Nephrectomy. Especially it is more desirable to participate of paramedical personnels such as the religious, the social workers, the counsellors, and etc when assess the motivation of kidney donor and to use of a formulated visual educational materials about renal angiography and nephrectomy which required written consent of kidney donor. Further more, the donor should be educated sufficiently about the kidney itself and procedure for nephrectomy-the anatomical position of kidney, the function of the kidney, the operative maneaver, pre and post operative complication, the prevention of the complication, the possiblity of rejection phenomenon and loss of the transplanted kidney etc. In conclusion, medical team members for kidney transplantation must suggest not only physical problem but also psychological problem And the educated donor ought to have enough time before a making decision and all these process should be recorded in medical records

This study purports to investigate the determinants of individual personnel rating of the employees at a university hospital in Seoul, Korea. The sample used in this study consisted of 63 nurses, 41 para-medical staff (Clinical Pathologist, and Radiologist), and 67 administrative staff. Independent variables of the study included the achievement level of the selection test (English, major subject, and interview), post-entrance development factors (education and training, career development, supervisory support, co-worker support, and organizational support), and demographic characteristics. Data for the achievement level of the entrance exam and years for the first promotion were collected from the administrative records of the study hospital, while data for the post-entrance development factors were collected from the survey with self-administered questionnaires using 5-point Likert Scale during June 10-25, 2003. Collected data were analyzed using hierarchical multiple regression. The results of the study showed that achievement level of the interview and English exam at the selection test, education and training, organizational support, and supervisory support while working at the hospital, and length of duration (below 8 years) and educational background (4-year college graduates) among demographic variables had significant positive effects on the personnel rating. The results of the study imply that hospital administrators should make an effort to improve the validity of the selection test, and to motivate the employees to receive more education and training.

Purpose: Express mail service(EMS) supplied by 'Korea POST'is an international postal service which brings letters, documents and parcels to a destination abroad in the fastest and safest way. This service is in a tough competition with global companies such as TNT, FedEx, DHL or UPS. To build an effective strategy for being competitive, an intensive study on EMS service quality should be accomplished from a customer's perspective. Methods: Kano model and improvement gap analysis are used to categorize and prioritize EMS service quality attributes. A 5-point Lickert scale is employed to apply the Kano model and improvement gap analysis. Each quality attribute can be classified as weak in comparison with competitors, critical for improvement, or potentially competitive. Results: Price, on-time delivery and delivery quality are to be kept as is; fast delivery, parking convenience and staff expertise can be potentially competitive; and the other attributes are considered to be critical for improvement. Conclusions: Fast reimbursement and proper compensation when shipping items are lost or damaged are to be improved with high priority. Efforts to secure fast delivery, parking convenience and staff expertise are needed to be competitive in the future.

Most of weapon purchasing countries in the world are using offset trade as an important negotiation means of foreign trade. In particular, Japan and Israel have obtained good results in the new projects and finding a new market for the long run through the offset trade. On the other hand, the USA holds much weight in the aspect of Republic of Korea's record of offset trade performance. However, compared with the record, her achievement known concretely has been evaluated insufficiently. Therefore, we suggest the improvement plans of the offset trade drive systems in this study. So that we analyze foreign countries' priority by offset trade type against the USA, the American offset trade object and priority and the case study of offset trade's post valuation plan. Moreover, we extract management problems of assets and technical materials obtained through the offset trade.

The adoption of technology has always been of interest to academicians and practitioners of the field of Management Information System. This is so because without proper and adequate adoption, technology-no matter how beneficial or advanced it may be-will be of little value to users. Numerous researches, such as the researches of the Technology Acceptance Model (TAM) or the Unified Theory of Acceptance and Use of Technology (UTAUT), had been conducted to understand the human nature in association with the adoption or rejection of technologies that have bombarded the users. The coming of smart technologies (i.e., smart phones and devices), however, seems to have fundamentally changed the environment for adoption. The ubiquity combined with mobility of technology, especially when it comes to mobile apps, seem to make the old PC era of two-stage-pre and post-adoption models obsolete. A new model of adoption that identifies the determinants of technology acceptance and continuance is needed for the smart age. To this end, this paper undertakes an empirical study, by analyzing 229 users of Social Networking Service (SNS) mobile apps, to identify the role of user experience on the multi-stage adoption of technology, and provides results that User Experience (UX) plays the crucial role of bridging the separate stages of pre and post adoption of technologies. The paper concludes by providing practical implications of the new model as it relates to mobile apps and technologies, and recommendations for further studies to get a better understanding of technology adoption in the smart age.

Tracheo-innominate artery fistula (TIF) is a rare but catastrophic and almost always fatal complication of tracheostomy. TIF can occur anytime but is commonly present 3 to 24 days after tracheostomy. It can first manifest as massive bleeding around and through the tracheostomy tube, but it can also manifest as a small amount of blood with temporary spontaneous resolution. If TIF is suspicious, airway management and prompt surgical intervention are needed. In an 83-year-old man with CVA history 20 years earlier and who had recurrent aspiration pneumonia, tracheostomy was performed for respiratory management and ventilator support. On day 7 post-tracheostomy, the patient had bleeding from the tracheostoma. Immediate surgical exploration was performed to control the bleeding. A defect was seen at the post wall of the innominate artery. The erosive portion of the artery was sutured, but the patient died three weeks after the surgery due to rebleeding and respiratory failure. We present a patient who developed TIF after tracheostomy, with literature review.
