Purpose: Undernutrition during hospitalization increases the risk of nosocomial infection and lengthens the disease courses. The aim of this study was to evaluate the risk factors of weight loss during hospitalization in children. Methods: All the patients who were admitted in general wards between April and May 2014 were enrolled. Patients aged >18 years and discharged within 2 days were excluded. Weight loss during hospitalization was defined as a decrease in body weight of >2% in 8 hospital days or on the day of discharge. Patients who lost body weight during hospitalization were compared with patients who maintained their body weights. Significant parameters were evaluated by using the multivariate logistic regression analysis. Results: We enrolled 602 patients, of whom 149 (24.8%) lost >2% of their body weight. Complaint of pain (p=0.004), admission to the surgical department (p=0.001), undergoing surgery (p=0.044), undergoing abdominal surgery (p=0.034), and nil per os (NPO) durations (p=0.003) were related to weight loss during hospitalization. The patients who had high weight-for-age tended to lose more body weight (p=0.001). Admission to the surgical department (odds ratio [OR], 1.668; 95% confidence interval [CI], 1.054-2.637; p=0.029) and long NPO durations (OR, 1.496; 95% CI, 1.102-2.031; p=0.010) were independent risk factors of weight loss during hospitalization. The patients with high weight-for-age tended to lose more weight during hospitalization (OR, 1.188; 95% CI, 1.029-1.371; p=0.019). Conclusion: Greater care in terms of nutrition should be taken for patients who are admitted in the surgical department and have prolonged duration of nothing by mouth.

Antiphospholipid syndrome is a thrombotic disorder characterized by the association of arterial and venous thrombosis with the antibodies directed toward phospholipids. The presence of these antibodies in systemic lupus erythematosus(SLE) has been shown to be related to several clinical and analytical alterations. We experienced one case of lupus nephritis with positive antiphospholipid antibodies in a 10-year-old girl whose chief complaint was persistent microscopic hematuria. We report this case with a brief review of related literatures. (J. Korean Soc Pediatr Nephrol 2001 ;5 : 219-24)

Background : Vertigo is a very common complaint in clinical practice. The number of patients who complain of vertigo has been increasing due to rapid growth of the elderly population. This study was designed to review the clinical features and success of oriental medical treatment of positional vertigo. Methods : This observation was made on 70 subjects diagnosed with positional vertigo. They were hospitalized in the Semyung University Oriental Medicine Hospital. Results : The results were as follows 1. Female patients (82.9%) were more than male patients. The most common age group was 8th decade and the patients rapidly increased after the 5th decade of age. 2. The most common past history of positional vertigo was hypertension, the second was cerebral infarction, and the third was hyperlipidemia. 3. In the oriental medicine diagnosis, phlegm-dampness syndrome (痰濕交阻 眩暈) was the most common disease (92.9%), and in western medicine, BPPV was the most (82.9%). 4. In herbal medication, Banhabaekchulchunma-tang gami (45.7%) was the most commonly used, the second being Taeksa-tang (30%). 5. The vertigo score of 94.3% patients improved and none got worse. 6. In general characteristics, men over 64 years improved best. Past history had no effect on the improvement of vertigo. 7. The sooner patients visited hospital after onset, the shorter hospitalization time was. Conclusions : Vertigo attacks patients well in advanced age, with various causative diseases. Oriental medical treatments have considerable effects on positional vertigo, especially treated with Banhabaekchulchunma-tang gami and Taeksa-tang.

Dynamic response analysis of offshore triceratops with stiffened buoyant legs under impact and non-impact waves is presented. Triceratops is relatively new-generation complaint platform being explored in the recent past for its suitability in ultra-deep waters. Buoyant legs support the deck through ball joints, which partially isolate the deck by not transferring rotation from legs to the deck. Buoyant legs are interconnected using equally spaced stiffeners, inducing more integral action in dispersing the encountered wave loads. Two typical nonlinear waves under very high sea state are used to simulate impact and non-impact waves. Parameters of JONSWAP spectrum are chosen to produce waves with high vertical and horizontal asymmetries. Impact waves are simulated by steep, front asymmetric waves while non-impact waves are simulated using Stokes nonlinear irregular waves. Based on the numerical analyses presented, it is seen that the platform experiences both steady state (springing) and transient response (ringing) of high amplitudes. Response of the deck shows significant reduction in rotational degrees-of-freedom due to isolation offered by ball joints. Weak-asymmetric waves, resulting in non-impact waves cause steady state response. Beat phenomenon is noticed in almost all degrees-of-freedom but values in sway, roll and yaw are considerably low as angle of incidence is zero degrees. Impact waves cause response in higher frequencies; bursting nature of pitch response is a clear manifestation of the effect of impact waves on buoyant legs. Non-impact waves cause response similar to that of a beating phenomenon in all active degrees-of-freedom, which otherwise would not be present under normal loading. Power spectral density plots show energy content of response for a wide bandwidth of frequencies, indicating an alarming behaviour apart from being highly nonlinear. Heave, being one of the stiff degrees-of-freedom is triggered under non-impact waves, which resulted in tether tension variation under non-impact waves as well. Reduced deck response aids functional requirements of triceratops even under impact and non-impact waves. Stiffened group of buoyant legs enable a monolithic behaviour, enhancing stiffness in vertical plane.

Background: Polyps are common lesions in the gastrointestinal (GI) tract. Colon cancer is mostly a result of progression from polyps. The present study aimed to evaluate demographic, clinical, and histological characteristics of colorectal polyps in Iran, particularly neoplastic and advanced types. Materials and Methods: Over a period of 10 years, specimens of all colorectal polyps obtained from colonoscopy were studied. The variables subjected to statistical analysis were age, sex, and the chief clinical complaint of the patients who underwent colonoscopy, their motivation, and the site, size, and histological types of detected polyps. The level of significance was set at p value <0.05. Results: Data were obtained from a total of 352 patients. No difference was seen between male and female patients regarding histological types. Only in nine patients was screening the reason for colonoscopy. Almost two-thirds (66.2%) of the polyps were neoplastic. Familial polyposis syndrome and inflammatory bowel disease were seen in 4.3% and 3.0% of the patients with neoplastic polyps, respectively. Sites of polyps were the sigmoid, rectum, and descending colon in 40.1%, 34.5%, and 17% of the cases, respectively. The advanced type made up 58.8% of neoplastic polyps. Only 3.6% of the patients undergoing colonoscopy in the study period had biopsied polyps. Discussion: No difference was observed between male and female patients in terms of overall incidence of polyps, histological and anatomical profiles, and mean age distribution. Anatomical and histological profiles agreed with the studies performed in areas with a low risk of colon cancer. The findings show that colonoscopy was not performed when it was necessary. A meaningful increase in the number polyp biopsy cases and a corresponding decrease in polyp size in the last few years of the study can be associated with the presence of more GI specialist clinicians in hospital centers, and this holds out much hope for the further improvement of the situation in the future.

The measurement of information system (IS) effectiveness is critical to understanding of the value and efficacy of IS actions and IS investments. In this paper, we propose a new model of the user satisfaction index for ISs and present the user satisfaction index which is measured by the proposed model. Based on the representative theories and models in the field of marketing and IS, we propose a new user satisfaction index model and verify the new model through the analysis of structural equation model. The proposed model consists of four basic dimensions : information quality, service quality, systems quality, and user satisfaction. Also, users' royalty and complaint are adopted as the additional dimension in this model. Data was collected from the ITFIND users to measure their satisfaction index. We, then, suggest some strategic guidelines for the better ITFIND which may useful when the system designers consider upgrading of the system in the future.

Purpose: The association between pain and sleep is described as a vicious cycle and psychological distress is well known as comorbid condition in the patients with pain and sleep problems. The aim of the study was to evaluate the prevalence of self-reported sleep disturbance and its relationship to clinical and psychological profiles in temporomandibular disorder (TMD) patients. Methods: The sample consisted of 123 TMD patients (90 women and 33 men), with a mean age of $39.9{\pm}15.4years$. Self-report measures of sleep quality, pain and psychological profile were conducted via the Pittsburgh Sleep Quality Index (PSQI), the Brief Pain Inventory and the Symptom Checklist-90-Revision at the initial visit. The primary diagnosis of TMD were categorized as TMD with internal derangement without pain, TMD with joint pain, TMD with muscle pain and TMD with joint-muscle combined pain. The chi-square test, independent t-test, oneway ANOVA and multiple linear regression analysis were used for statistics. Results: The patients was grouped as good sleepers (n=32, scores of 5 and lower) and poor sleepers (n=91, scores of 6 and higher) according to the recommended cutoff point of the global PSQI score (>5). TMD patients with pain showed poor sleep quality than TMD patients with internal derangement without pain. Poor sleepers had high pain interference and elevated psychological distress. Among them, pain interference and depression were significant predictors to sleep quality. Conclusions: The results suggest that sleep disturbance is a prevalent complaint in TMD patients, and sleep problems in TMD patients are associated with pain and psychological distress.

Background: It is well known that nasotracheal intubation is comfort for patient compared to oral intubation. We sometimes delay extubation when it is thought that the patient can not maintain airway, or there may be other emergency associated with airway. And we sometimes experience complaint of discomfort of nasotracheal tube. But, we could not find any report on degree of discomfort of delayed nasotracheal intubation. Methods: Eighteen patients in whom extubation of nasotraceal tube was delayed after operation because of difficulties of airway mamagement were selected. We surveyed the discomfort of nasotracheal tube with 0 to 10 visual analogue scale (VAS) and compared with the pain of operation site (VAS). Result: The VAS of nasotracheal intubation was $6.7{\pm}3.4$, and VAS of the primary operation site was $3.5{\pm}2.4$, and VAS of flap harvest site was $5.5{\pm}2.7$. 10 of the patients complained of nasotracheal suction extremely and 6 patients complained of respiratory difficulties. Conclusions: Nasotracheal intubation was discomfort and there must be intervention.

This study was aimed to identify the current status of medical service quality of medical institutes; propose improvements; and find out the impact of medical service quality by its attribute on overall customer satisfaction. The research was conducted on the out-patients and in-patients in a high-level general hospital located in A city. To examine the research, the IPA was utilized to identify the priority requirements for improving the medical service quality. The study also applied an extended theory to the analysis on mismatch between the level of satisfaction and importance recognized by the clients, to examine the impact of the above mentioned factors on the overall satisfaction and intention to revisit and recommend the hospital. For out-patients, the result showed that "hospital hygiene" had a positive and negative impact on the clients' intention to revisit the hospital in priority improvements. In terms of the sustainable improvements, "doctor's skill" had a negative impact on the overall service satisfaction, whereas "state-of-the-art facility" and "nurse's instruction" had a positive impact on the intention to revisit the hospital. In long-term improvements,"complaint remedy" had a positive impact on the intention to recommend the hospital but there were no relevant factors in excessive investment. On the other hand, for in-patients, the result demonstrated that there were no relevant factors in priority improvements and sustainable improvements. The factor of"service procedure speed"had a positive as well as negative impact on the intention to revisit the hospital. In excessive investment,"nurse's empathy"had a positive impact on the intention to recommend the hospital.
