Measuring and evaluating the business performance plays a very important role in managing business. It is because business performance, in any types of industry, can be evaluated and managed properly only when the measurement of its performance is estimated, and because its performance can be improved through an efficient and effective management. Therefore it is essential to build up the performance evaluation system to raise management efficiency of the foodservice industry, to reinforce competitive power of the food service industry. This study tried to propose a novel point of prospective and method in which the performance evaluation in any family restaurant should be illuminated and be performed. In this study, BSC provided the main conceptional framework for evaluating the performance of a family restaurant, and evaluation items of BSC four prospectives - financial, customers, internal business process, and learning and growth-were adjusted so as to be fitted into the business field. Furthermore, this study verified the validity of the proposed performance evaluation method through specific case analyses and used AHP to quantify its validity objectively. Finally, this study found the fact that non-financial prospectives, compared to financial prospectives, should be more importantly considered as the performance evaluation index of the family restaurants. Especially, the study showed that the proportion of performance evaluation indexes related to Customers prospective and Learning and Growth prospective revealed very highly, therefore variables such as customer satisfaction index, per employee productivity, education and training, customer response rate, employee satisfaction index should be emphasized as key factors at the process of selecting indexes and measuring their performance evaluation of the food service industry.

Background: Despite our knowledge of the causes of cancer, millions of workers are involuntarily exposed to a wide range of known and suspected carcinogens in the workplace. To address this issue from a policy perspective, we developed a policy framework based on a prospective health policy analysis. Use of the framework was demonstrated for developing policies to prevent cancers associated with diesel engine exhaust (DEE), asbestos, and shift work, three occupational carcinogens with global reach and large cancer impact. Methods: An environmental scan of existing prospective health policy analyses was conducted to select and describe our framework parameters. These parameters were augmented by considerations unique to occupational cancer. Policy-related resources, predominantly from Canada, were used to demonstrate how the framework can be applied to cancers associated with DEE, asbestos, and shift work. Results: The parameters of the framework were: problem statement, context, jurisdictional evidence, primary prevention policy options, and key policy players and their attributes. Applying the framework to the three selected carcinogens illustrated multiple avenues for primary prevention, including establishing an occupational exposure limit for DEE, banning asbestos, and improving shift schedules. The framework emphasized the need for leadership by employers and government. Conclusion: To our knowledge, this is the first proposal for a comprehensive policy framework dedicated to the primary prevention of occupational cancer. The framework can be adapted and applied by key policy players in Canada and other countries as a guide of what parameters to consider when developing policies to protect workers' health.

최근 수학 교사교육에 관한 관심의 증가로 다양한 연구가 이루어져 왔으나 교사를 어떻게 교육하는가에 대한 실천적 연구는 매우 부족하다. 예비교사교육에서 수학 교수법에 관한 연구는 교사교육자 스스로의 반성이나 다른 동료교수의 수업을 관찰하는 방법으로 이루어질 수 있다. 본 논문은 연구자가 미국의 캘리포니아 주립대학교에서 예비 초등교사를 위한 수학교수법 강좌를 참여관찰의 방법으로 탐색한 결과를 자세히 기술하고 이로부터 예비교사교육에 대한 시사점을 도출하고자 하였다. 특히 이 강좌는 예비초등교사의 수학과 수업 전문성을 신장시키기 위한 구체적인 목적을 가지고 전형적인 교사교육과는 다른 방법으로 수업을 구현했기 때문에, 우리나라 교사교육자에게 대안적인 수학교수법에 대한 통찰을 제공하고 이론과 실제를 접목한 교사교육 프로그램에 대한 논의를 이끌 수 있을 것으로 기대된다.

Purpose: There is controversy regarding the cosmetic outcome after accelerated partial breast radiation (APBR). We report the cosmetic outcome from a single-arm prospective clinical trial of APBR delivered using intensity-modulated radiation therapy (IMRT) in elderly patients with stage I breast cancer (BC), using a novel fractionation schedule. Materials and Methods: Forty-two patients aged ${\geq}65$, with Stage I BC who underwent breast-conserving surgery were enrolled in a phase I/II study evaluating a 2-week course of APBR. Thirty eligible patients received 40 Gy in 4 Gy daily fractions. Cosmetic outcome was assessed subjectively by physician/patient and objectively by using a computer program (BCCT.core) before APBR, during, and after completion of the treatment. Results: The median age was 72 years, the median tumor size was 0.8 cm, and the median follow-up was 50.5 months. The 5-year locoregional control in this cohort was 97% and overall survival 87%. At the last follow-up, patients and physicians rated cosmesis as 'excellent' or 'good' in 100% and 91 %, respectively. The BCCT.core program scored the cosmesis as 'excellent' or 'good' in 87% of the patients at baseline and 81% at the last follow-up. The median $V_{50}$ (20 Gy) of the whole breast volume (WBV) was 37.2%, with the median WBV $V_{100}$ (40 Gy) of 10.9%. Conclusion: An excellent rate of tumor control was observed in this prospective trial. By using multiple assessment techniques, we are showing acceptable cosmesis, supporting the use of IMRT planned APBR with daily schedule in elderly patients with early stage BC.

Objectives : To determine the impacts of Diagnosis-Related Groups/Prospective Payment System (DRG/PPS) on the quality of care in cases of Cesarean section and to describe the policy implications for the early stabilization of DRG/PPS in Korea. Methods : Data was collected from the medical records of 380 patients who had undergone Cesarean sections in 40 hospitals participating in the DRG/PPS Demonstration Program since 1999. Cesarean sections were peformed in 122 patients of the FFS(Fee-For-Service) group and 258 patients of the DRG/PPS group. Measurements of quality used included essential tests of pre- and post-operation, and the PPI(Physician Performance Index) score. The PPI was developed by two obstetricians. Results : Univariate analysis demonstrated significant differences in PPI scores according to the payment systems. With respect to the mean of PPI scores, a higher score was found in the DRG/PPS group than in the FFS group. However, the adjusted effect did not show significant differences between the FFS group and the DRG/PPS group. Conclusion : This study suggested that the problem of poor quality may not be related to the implementation of DRG/PPS in Cesarean section. However, this study did not consider the validity and reliability of the process measurement, and it did not exclude the possibility of data emission in medical records.

We conducted a prospective cohort study to evaluate the preventive effect of ginseng on the development of cancer in the population over 40 years old residing in Kangwha-eup from August 1987 to December 1992. Alnong 4, 634 persons (2, 362 men, 2, 272 women), 335 (7.6%) persons had died. Cancer accounted for 79 (22.8%) of the total death. Of 4, 634 persons eligible for analysis, 70.475 (3, 263) were ginseng intakes. Ginseng intakes had a decreased risk (RR=0.48, 95% Cl : 0.34~0.67) compared with non-intakes. The relative risk of cancer according to the kind of ginseng was 0.23 (95% Cl : 0.08~ 0.63) for fresh ginseng extract intakes. There was a decrease in risk with rising the frequency of ginseng intake, showing statistically significant dose-response relationship. The longer the duration of ginseng intake or the greater the total number of ginseng consumed, the lower the risk. Newly diagnosed cancer cases have been identified: 42 stomach, 24 lung, 14 liver and 57 at other sites. The relative risks of ginseng intakes were 0.34 (95% Cl 0.19~0.60) in gastric cancer and 0.27 (95% Cl : 0.12-0.60) in lung cancer. Among ginseng preparations, fresh ginseng intakes were significantly associated with the decreased risk of gastric cancer (RR: 0.19, 95% Cl : 0.04~0.98). These results strongly revealed that Panax Ginseng C.A. Meyer (Korean ginseng) has preventive effect against cancer.

Study Design: Prospective observational study. Purpose: To determine the incidence of postoperative urinary retention (POUR) in patients undergoing elective posterior lumbar spine surgery and identify the risk factors associated with the development of POUR. Overview of Literature: POUR following surgery can lead to detrusor dysfunction, urinary tract infections, prolonged hospital stay, and a higher treatment cost; however, the risk factors for POUR in spine surgery remain unclear. Methods: A prospective, consecutive analysis was conducted on patients undergoing elective posterior lumbar surgery in the form of lumbar discectomy, lumbar decompression, and single-level lumbar fusions during a 6-month period. Patients with spine trauma, preoperative neurological deficit, previous urinary disturbance/symptoms, multiple-level fusion, and preoperative catheterization were excluded from the study. Potential patient- and surgery-dependent risk factors for the development of POUR were assessed. Univariate analysis and a multiple logistical regression analysis were performed. Results: A total of 687 patients underwent posterior lumbar spine surgery during the study period; among these, 370 patients were included in the final analysis. Sixty-one patients developed POUR, with an incidence of 16.48%. Significant risk factors for POUR were older age, higher body mass index (BMI), surgery duration, intraoperative fluid administration, lumbar fusion versus discectomy/decompression, and higher postoperative pain scores (p<0.05 for all). Sex, diabetes, and the type of inhalational agent used during anesthesia were not significantly associated with POUR. Multiple logistical regression analysis, including age, BMI, surgery duration, intraoperative fluid administration, fusion surgery, and postoperative pain scores demonstrated a predictive value of 92% for the study population and 97% for the POUR group. Conclusions: POUR was associated with older age, higher BMI, longer surgery duration, a larger volume of intraoperative fluid administration, and higher postoperative pain scores. The contribution of postoperative pain scores in the multiple regression analysis was a significant predictor of POUR.

BACKGROUNDS/OBJECTIVES: Cancer treatment may lead to significant body composition changes and affect growth and disease outcomes in pediatric cancer patients. This prospective study aimed to evaluate short- and long-term body compositions changes focused on body fat during the first year of cancer treatment in children. SUBJECTS/METHODS: A prospective study was conducted in 30 pediatric cancer patients (19 hematologic malignancies and 11 solid tumors) and 30 age- and sex-matched healthy controls. Anthropometric measurements and body composition analysis using whole body dual energy X-ray absorptiometry were performed at baseline and 1, 6, and 12 month(s) of cancer treatment. Kruskal-Wallis tests, Wilcoxon paired t tests, and generalized estimation equation (GEE) were applied for statistical analysis. RESULTS: At baseline, no differences in weight, height, body mass index, abdominal circumferences, body fat, and fat-free mass were observed between 30 controls and 30 pediatric cancer patients. Total fat mass (P < 0.001) and body fat percentage (P = 0.002) increased significantly during the first month, but no changes were observed from 1 to 12 months; however, no changes in the total mass were observed during the first year of cancer treatment. Meanwhile, the total fat-free mass decreased during the first month (P = 0.008) and recovered between 6 and 12 months of follow-up (P < 0.001). According to GEE analysis, there was a significant upward trend in body fat percentage during the first year, especially the first month, of cancer treatment in children with hematologic malignancies, but not in those with solid tumors. CONCLUSIONS: Our results indicate that cancer treatment is related to significant body composition changes and rapid body fat gain, particularly during the first month after initiating cancer treatment, in children with hematologic malignancies. Therefore, individualized dietary strategies to prevent excessive fat gain are needed in pediatric cancer patients for better outcomes.
