The purpose of this study is to forecast patient satisfaction and service value through the staged regression analysis of the relation between each factor and its satisfaction and service value, following the measurement of the quality of dental care service that patients recognize. And a self-administered survey was used for this study. The subjects of this survey were 394 outpatients of dental clinics located in K city in the period from Dec. 5, 2004 to Feb. 19, 2005, the questionnaire was composed of a total of 31 questions to measure the quality of overall dental care service(22 questions), the patient satisfaction(6 questions) and the service value(3 questions). The 7 points Likert scale ranging from "very poor"(1-point) to "very high"(7-point) was used for these questions The results of study could be summarized as follows: 1. The most useful index to predict patient satisfaction turned out to be "internal environment", followed by "treatment process and waiting time", "dentist", "external environment", and "dental hygienist". 2. The service value had a significant effect on the "internal environment", "dentist", "treatment process and waiting time". 3. The most useful index to predict the service value turned out to be "treatment process and waiting time", followed by "internal environment" and "dentist". Today, the quality of dental care service is becoming a prime concern since it is directly connected to a matter of survival of medical service organizations. Dental clinics desperately need patient-oriented marketing strategies in order to actively cope with changing medical environment. They also need to thoroughly examine possible measures to maximize the service value by establishing a variety of service strategies which can promote service quality that patients recognize.

This study evaluated the effects of stocking density on performance and behavioral activities of 35-day-old broilers in relation to incandescent white bulb (IB) light and LED yellow and white light. A total of 1,650 day-old chicks were weighed and randomly allocated into six treatment groups in a 2 × 3 factorial arrangement based on stocking density (14 birds m^-2 and 22 birds m^-2) and color of lights (IB; monochromatic LED yellow and white light) with five replicates for each treatment. The results showed that final body weight, weight gain and feed conversion of broilers were improved at a stocking density of 14 birds m^-2 with exposure to LED lights. Similarly, broilers spent more time exhibiting inactive behavior (e.g. standing) and active behaviors (e.g. walking and walking plus pecking) under 14 birds m^-2 with exposure to lights as compared that of other treatment groups. Regarding a stocking density of 22 birds m^-2, broilers performance traits were negatively affected and also activities were less. The performance of broilers was not significantly altered for the main factor of different lights but broilers were less inactive (e.g less time spent sitting plus standing) and more time spent active behavior in walking under IB light than LED light. Thus, we concluded that a stocking density 14 birds m^-2 with exposure to LED light significantly improved broiler performance and behavioral activity and these conditions could therefore improve the overall welfare of farmed chickens.

Background: To evaluate the rate of pathologic high-risk factors, intermediate-risk factors, and treatment outcomes in early-stage cervical cancer patients undergoing radical hysterectomy and pelvic lymphadenectomy (RHPL). Materials and Methods: Medical records of stage IA-IIA1 cervical cancer patients who underwent RHPL during the 2006 to 2012 time period and patient follow-up data until December 2013 were reviewed. Results: Of 331 patients, 52 women (15.7%) had pathologic high-risk factors and 59 women (17.8%) had intermediate-risk factors without high-risk factors. All studied patients had an initial complete response. At median follow-up time of 40.9 months (range 1-103.3 months) and mean follow-up time of$ 43.3{\pm}25.3$ months, 37 women had disease recurrence and 4 women had died of disease. The most common site of recurrence was the pelvis (64.8%). Five-year and 10-year disease free survival rates were 96.1% and 91.5%, respectively. Five-year and 10-year overall survival rates were 100% and 99.4%, respectively. Independent factors related to recurrence were pelvic node metastasis (odds ratio [OR], 2.670; 95%CI, 1.001-7.119), and >1/3 cervical stromal invasion (OR, 3.763; 95%CI, 1.483-9.549). Conclusions: The rates of pathologic high-risk and intermediate-risk factors should be considered and disclosed when counseling patients regarding primary treatment by RHPL. Oncologic outcomes of primary surgical treatment for early-stage cervical carcinoma were found to be excellent.

Objective: To observe the short-term efficacy, long-term survival time and adverse responses with nedaplatin (NDP) or cisplatin (DDP) concomitant with other chemotherapy in treating non-small cell lung cancer. Materials and Methods: A retrospective, randomized, control study was conducted, in which 619 NSCLC patients in phases III and IV who were initially treated and re-treated were randomly divided into an NDP group (n=294) and a DDP group (n=325), the latter being regarded as controls. Chemotherapeutic protocols (CP/DP/GP/NP/TP) containing NDP or DDP were given to both groups. Patients in both groups were further divided to evaluate the clinical efficacies according to initial and re-treatment stage, pathological pattern, type of combined chemotherapeutic protocols, tumor stage and surgery. Results: The overall response rate (ORR) and disease control rate (DCR) in the NDP group were 48.6% and 95.2%, significantly higher than in the DDP group at 35.1% and 89.2%, respectively (P<0.01). In NSCLC patients with initial treatment, squamous carcinoma and phase III, there were significant differences in ORR and DCR between the groups (P<0.05), while ORR was significant in patients with adenocarcinoma, GP/TP and in phase IIIa (P<0.05). There was also a significant difference in DCR in patients in phase IIIb (P<0.05). According to the statistical analysis of survival time of all patients and of those in clinical phase III, the NDP group survived significantly longer than the DDP group (P<0.01). The rates of decreased hemoglobin and increased creatinine, nausea and vomiting in the NDP group were evidently lower than in DDP group (P<0.05). Conclusion: NDP concomitant with other chemotherapy is effective for treating NSCLC, with higher clinical efficacy than DDP concomitant with chemotherapy, with advantages in prolonging survival time and reducing toxic and adverse responses.

Objectives: Primary malignant tumors in the salivary glands are relatively rare. Because of the rarity and the different histopathologic patterns, it is difficult to establish a uniform treatment strategy. The prime treatment of salivary gland malignancy is the surgery, but the role of radiotherapy has been under debate. Radiation therapy combined with conservative surgical procedures may be as successful and perhaps more rational treatment than radical surgery alone. The aim of this study is to evaluate clinical pattern, incidence, treatment modality and outcome of the salivary gland maligancy. Materials and Methods: The medical records of 32 patients with malignant neoplasm of salivary gland who treated at the Keimyung university Dongsan hospital were analyzed retrospectively. Results: The overall 5 year survival rate was 77.9% stage I : 100%, stage II : 75%, stage III : 66.7%, stage IV : 55.6%). The 5 year survival rate according to tumor grade was 100% in low grade malignancy, 71.8% in high grade malignancy. The 5 year survival rate according to treatment modalities was as follows: Surgery only group was 83.3%, combined treatment group with surgery and posoperative radiation was 74.6%. Conclusion: The factors affecting prognosis is variable, but the stage at the time of diagnosis, site of lesion, tumor grade, histologic subtype were important factors. Surgery was the prime treatment tool and postoperative radiotherapy was also imperative in higher stage patient, high grade tumor, or patients with positive surgical margin.

Background: Surgery has been the classical treatment of pectus carinatum (PC), though compressive orthotic braces have shown successful results in recent years. We propose a non-operative approach using a lightweight, patient-controlled dynamic chest-bracing device. Materials and Methods: Eighteen patients with PC were treated between July 2008 and June 2009. The treatment involved fitting of the brace, which was worn for at least 20 hours per day for 6 months. Their degree of satisfaction (1, no correction; 4, remarkable correction) was measured at 12 months after the initiation of the treatment. Results: Thirteen (72.2%) patients completed the treatment (mean time, $4.9{\pm}1.4$ months). In patients who completed the treatment, the mean overall satisfaction score was $3.73{\pm}0.39$. The mean satisfaction score was 4, and there was no recurrence of pectus carinatum in patients who underwent the treatment for at least 6 months. Minimal recurrence of pectus carinatum after removal of the compressive brace occurred in 5 (38.5%) patients who stopped wearing the compressive brace at 4 months. Conclusion: Compressive bracing results in a significant improvement in PC appearance in patients with an immature skeleton. However, patient compliance and diligent follow-up appear to be paramount for the success of this method of treatment. We currently offer this approach as a first-line treatment for PC.

Objective : The treatment of choice for spinal epidural abscess (SEA) generally is urgent surgery in combination with intravenous antibiotic treatment. However, the optimal duration of antibiotic treatment has not been established to date, although 4-8 weeks is generally advised. Moreover, some researchers have reported that bacteremia is a risk factor for failure of antibiotic treatment in SEA. In this study, we investigated the clinical characteristics of SEA accompanied by bacteremia and also determined whether the conventional 4-8 weeks of antibiotic treatment is sufficient. Methods : We retrospectively reviewed the medical records and radiological data of 23 patients with bacterial SEA who underwent open surgery from March 2010 to April 2020. All patients had bacteremia preoperatively and underwent weeks of perioperative antibiotic treatments based on their identified organisms until all symptoms of infection disappeared. All patients underwent microbiological studies of peripheral blood, specimens from SEA and concomitant infections. The mean follow-up duration was 35.2 months, excluding three patients who died. Results : The male : female ratio was 15 : 8, and the mean age was 68.9 years. The SEA most commonly involved the lumbar spinal segment (73.9%), and the mean size was 2.9 vertebral body lengths. Mean time periods of 8.4 days and 16.6 days were required from admission to diagnosis and from admission to surgery, respectively. Concomitant infections more frequently resulted in delayed diagnosis (p=0.032), masking the symptoms of SEA. Methicillin-sensitive Staphylococcus aureus was the most commonly identified pathogen in both blood and surgical specimens. Seventeen patients (73.9%) showed no deficits at the final follow-up. The overall antibiotic treatment duration was a mean of 66.6 days, excluding three patients who died. This duration was longer than the conventionally advised 4-8 weeks (p=0.010), and psoas or paraspinal abscess required prolonged duration of antibiotic treatment (p=0.038). Conclusion : SEA accompanied by bacteremia required a longer duration (>8 weeks) of antibiotic treatment. In addition, the diagnosis was more frequently delayed in patients with concomitant infections. The duration of antibiotic treatment should be extended for SEA with bacteremia, and a high index of suspicion is mandatory for early diagnosis, especially in patients with concomitant infections.

PURPOSE: High-intensity physical therapy may help improve some gross motor developmental delays through an increased treatment frequency. This study describes an increase in physical therapy frequency and intensity over an eight-week time frame for a child with a rare genetic neurodevelopmental disorder. METHODS: A single-subject research was performed. The subject was a nine-year-old boy with MECP2 Duplication Syndrome. The outcome measure consisted of one time before and after the intervention. An intensive physical therapy program was applied to this subject. The treatments included reciprocal crawling, high kneeling, tailor sitting, weight-bearing and shifting training to facilitate ankle balance strategies and training to walk without assistance. RESULTS: After the eight-week follow-up, the child achieved a gradual improvement in the gross motor function measures, and the mother reported that the child frequently engaged in tailor sitting and independently walking. CONCLUSION: This case study highlights that intensive physical therapy improved the overall motor function of a child with MECP2 duplication syndrome.

Background: Docetaxel, cisplatin, 5-fluorouracil (DCF) given every three weeks is an effective, but palliative regimen and significantly toxic especially in patients who have a low performance score. Here, we aimed to evaluate the efficacy and tolerability of a weekly formulation of DCF in locally advanced and metastatic gastric cancer patients. Materials and Methods: 64 gastric cancer patients (13 locally advanced and 51 metastatic) whose ECOG (Eastern Cooperative Oncology Group) performance status (PS) was 1-2 and who were treated with at least two cycles of weekly DCF protocol as first-line treatment were included retrospectively. The weekly DCF protocol included $25mg/m^2$ docetaxel, $25mg/m^2$ cisplatin, and 24 hours infusion of $750mg/m^2$ 5-fluorouracil, repeated every week. Disease and patient characteristics, prognostic factors, treatment response, grade 3-4 toxicity related to treatment, progression free survival (PFS) and overall survival (OS) were evaluated. Results: Of the patients, 41 were male and 23 were female; the median age was 63 (29-82) years. Forty-one patients were ECOG-1 and 23 were ECOG-2. Of the total, 81.2% received at least three cycles of chemotherapy. Partial response was observed in 28.1% and stabilization in 29.7%. Overall, the disease was controlled in 57.8% whereas progression was noted in 42.2%. The median time to progression was 4 months (95%CI, 2.8-5.2 months) and median overall survival was 12 months (95%CI, 9.2-14.8 months). The evaluation of patients for grade 3-4 toxicity revealed that 10.9% had anemia, 7.8% had thrombocytopenia and 10.9% had neutropenia. Non-hematologic toxicity included renal toxicity (7.8%) and thrombosis (1.6%). Conclusions: In patients with locally advanced or metastatic gastric cancer who were not candidates for DCF administered every-3-weeks, a weekly formulation of DCF demonstrated modest activity with minimal hematologic toxicity, suggesting that weekly DCF is a reasonable treatment option for such patients.
