  • Thirty female and six male rats aged fourty days were divided into two groups in order to feed them by pairfeeding for 50% dietary restriction in the pair group two weeks interval. Each group contains 15 female and three male rats matched each rat between two groups in consideration of body weight. Two female groups, one fed by 50% restricted diet and other Ad Libitum were divided into four groups each by the duration of dietary restriction during pregnancy: First ten days dietary restriction at 50% level, Last ten days dietary restriction at 50% level, Dietary restriction at 50% level for full period, And dietary unrestriction for full period Urinary total nitrogen and creatinine were determined. The birth weights of offsprings were decreased partial and full period dietary restriction of pregnant rats. There was no significant difference in the litter size of progeny due to the maternal diets. The growth was stunted in offsprings from the mothers fed restricted diet at 50% level for full period of pregnancy. No effect in the body weight gain of offsprings was observed in account of partial period of maternal dietary restriction. The urinary nitrogen of offsprings from eight different groups did not show any statistically significant difference.

  • Propose: The expansion of the delivery market in franchise business is a positive means of advertising and promotion for franchisees and contributes to substantial sales growth for stores. However, unrestricted and uncontrolled delivery sales and business activity of franchisee directly lead to encroachment of business territory between franchisees, resulting in increased operating costs of franchisees and conflicts between franchisees over rights and interests on franchise business. Moreover, in relation to the restrictions on the opening of competitors, it is incapacitating the law intent of prohibiting unfair encroachment of business territory, in the issue of the Fair Franchise Act in regard to guarantee of exclusive sales and business activity rights of franchisee. This study aims to point out major problems arising out of franchisee's infinite competition on delivery sales and business activity that are not restricted or controlled and then suggest legal supplements, policy tasks, and practical implications for improvement on the issues. Literature Review: In franchising business transactions, vertical restraints are associated with the exclusive territory establishment, control of transaction area, restriction of intangible sales and business activity of franchisee. Therefore, in the franchise business, it is necessary to take positive interpretation and application on e-commerce, the area of e-commerce, and delivery trading area and find proper and practical ways, by virtue of constructive attitude of each actor, to reduce the encroachment of business territory and various conflicts caused by unrestricted delivery trading area. Conclusion and suggestion: The finding shows that unrestricted or uncontrolled delivery sales and business activity of franchisees cause encroachment of business territory and many conflicts among franchisees. And this matters also weaken the legislation of the law on the protection of the business territory and can be negative factors that disrupt the protection of identity and sound development of the franchise industry in the long run. Therefore, in the franchise business, it is necessary to take positive interpretation and application on e-commerce, the area of e-commerce, and delivery trading area and find proper and practical ways, by virtue of constructive attitude of each actor, to reduce the encroachment of business territory and various conflicts caused by unrestricted delivery trading area.

  • A development in method of evaluating the measurement precisions using approximate F tests and variance components from expected mean square (EMS) is investigated. The research proposes three-factor mixed measurement models with the fixed and random factors. Unrestricted and unconstrained design work was rarely studied, while restricted and constrained designs have been significantly discussed. The unrestricted and unconstrained designs assume to be an independence of interaction. The proposed evaluation method about the measurement precisions can be extended to four-factor random measurement model or mixed measurement model. The study also presents the three evaluation indexes of precisions such as R&RTR (Reproducibility & Repeatability-To-Total Precision Ratio), PTR (Precision-To-Tolerance Ratio), and SNR (Signal-To-Noise Ratio). Numerical examples are proposed to evaluate the approximate F tests with Satterthwaite degrees of freedom and three indexes using the measurement precisions from EMS.

  • Unrestricted measurement method of three-dimensional walking distance utilizing body acceleration and terrestrial magnetism is discussed. The three-dimensional walking distance is derived by the integration of the three dimensional acceleration of foot during swing phase. Since the sensor system attached on the foot rotates during swing phase, the acceleration data measured on the foot include acceleration of gravity which causes inaccurate calculation of the velocity and the distance. Three gyros are used to compensate the rotation of the sensor system. Moreover, one geomagnetic sensor is employed to derive the heading direction of the subject Healthy volunteers performed ...

  • Bayes estimation of parameters is considered for two independent exponential distributions with ordered means. Order restricted Bayes estimators for means are obtained with respect to inverted gamma, noninformative prior and uniform prior distributions, and their asymptotic properties are established. It is shown that the maximum likelihood estimator, restricted maximum likelihood estimator, unrestricted Bayes estimator, and restricted Bayes estimator of the mean are all consistent and have the same limiting distribution. These estimators are compared with the corresponding unrestricted Bayes estimators by Monte Carlo simulation.

  • The designed release rate of liquid effluents from radwaste treatment system should be calculated and evaluated during normal operation, including anticipated operational occurrence and be assured that the release concentration and off-site dose at unrestricted area do not exceed the limits of regulation. The expected annual release rate and off-site dose for the currently operating nuclear power plants in Korea had been calculated and evaluated using PWR-GALE and LADTAP-II which was based on USNRC Regulatory Guide 1.109. Recently, the MOST Notice 2001-2 related to release concentration and off-site dose at unrestricted area was revised to reflect the concept of ICRP-60. It is necessary for KORI 3&4 to re-calculate the release concentration and off-site dose and to compare these results with the limits of regulation. As the results of assessment, we confirmed that the release concentrations were less than its limits of MOST Notice 2001-2 and the off-site dose at unrestricted area using K-DOSE60 was 3.61E-03 mSv/yr to the age of five for the effective dose, and 4.10E-2 mSv/yr to thyroid of the age of five for the organ equivalent dose. We also confirmed the off-site dose was within the limits of MOST Notice 2001-2. Therefore, the release concentration and off-site dose re-evaluated at unrestricted area in KORI 3&4 were well below the regulation limits of MOST Notice 2001-2.

  • Purpose: This study reports on a series of patients with chronic lateral ankle instability that underwent the Brostrom procedure with suture tape augmentation and allowed early unrestricted weight-bearing in a simple stirrup brace. Materials and Methods: This retrospective study was conducted on 36 patients (22 males and 14 females of mean age 34 years [range 23~48 years]) with chronic lateral ankle instability treated using the Brostrom procedure using suture tape augmentation and inferior extensor retinaculum reinforcement with a fiber-wire connected to a SwiveLock screw inserted into the talus. When possible, patients started unrestricted weight-bearing in a stirrup brace from the third postoperative day. Demographics and functional outcomes, including American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot, visual analogue scale (VAS), and satisfaction scores, were recorded. In addition, varus stress radiographs obtained before and 24 months after surgery were compared. Patients were followed for a mean 29 months (range 25~40 months). Results: Mean AOFAS ankle-hindfoot scores increased from 51 points preoperatively to 92 points at final follow-up, and mean VAS decreased from 6.8 to 1.2 points. Mean patient satisfaction scores were 8.7 at 12 months and 9.6 at 24 months. Stress radiographs demonstrated that talar tilt decreased from a mean 18 degrees preoperatively to 7 degrees at 24 months. Conclusion: Early unrestricted weight-bearing in a stirrup brace following the Brostrom procedure with suture tape augmentation is a successful protocol for treating chronic lateral ankle instability.

  • The purpose of this study was to research the effects of students' evaluation results on teachers' teaching activities. The subjects were 431 elementary school students of 4th, 5th and 6th grade, and 14 teachers of 7 schools located in Seoul, Cheongju, and Daejeon city. The experimental design included pre and post-tests with the control group. Our results found that most of the students had positive thoughts towards science classes. In particular, activities where the teachers provided support in the conduct of experiments and the learning atmosphere generally were evaluated higher than other activities. However, unrestricted experiments were evaluated lower by the students. The feedback from the students' evaluation results of their teachers affected the teachers' teaching activities statistically. The teachers' support during experiments, unrestricted activity during experiments, and evaluation activities were changed positively following the students' feedback. However, the loaming atmosphere and unrestricted activity during experiments were observed to change negatively when the teachers were not given the students' feedback.
