A throttle/brake control law for the intelligent cruise control(ICC) systems has been proposed in this paper. The ICC system consists of a vehicle detection sensor, the control algorithm and a throttle/brake actuators. For the control of a throttle/brake system, we introduced a solenoid-valve-controlled electronic vacuum booster and a step-motor controlled throttle actuator. Nonlinear computer model for the electronic vacuum booster has been developed and the simulations were per formed using a complete nonlinear vehicle model. The results indicate the proposed throttle/brake control law can provide the ICC system with an optimized performance.

In this paper, I reviewed the analysis of possible ICC model of international sale contract terms used in the international artwork trade. Based on this, the provisions proposed considering the specialties of the international artworks trade. The purpose of this research study is to help practitioners draw up a contract of international artworks trade. In Chapter II, I reviewed the highlights of the international sale of goods contract. In Chapter III, I discussed the issues that arise in creating specific provisions on the international artworks trade agreements. In Chapter IV, I discussed the issues in creating the general provisions on the international artworks trade agreements. Quantity provisions of the international artworks sales contract should include the "more or less" clause. And it should also clearly define the scope of the author's property rights transfer in the copyright provisions. Even if a buyer has been assigned the copyright of artworks from the artist, if the buyer modifies the artworks without permission, moral rights can be violated. In addition, even if a buyer has been assigned all of the intellectual property rights of the artists, if the buyer does not have the specific provisions, the buyer must keep in mind that the unauthorized publication of artworks, film production, merchandising, etc, may infringe the right to create derivative works.

Muscle fatigue models to predict maximum endurance time (MET) are broadly classified as either 'empirical' or 'theoretical'. Empirical models are based on fitting experimental data and theoretical models on mathematical representations of physiological process. This paper examines the effectiveness of dynamic muscle fatigue model as theoretical model to predict maximum endurance time during forearm isometric contraction. Forty volunteers (20 females, 20 males) are participated in this study. Empirical models (exponential model and power model) and theoretical model (dynamic muscle fatigue model) are used to compare. Mean absolute deviation (MAD), correlation coefficient (r) and intraclass correlation (ICC) are calculated between theoretical model and empirical models. MAD are below 3.5%p, r and ICC are above 0.93 and 0.87, respectively. This results demonstrate that dynamic muscle fatigue model as theoretical model is valid to predict MET.

Franchising has proved over many years to be a successful commercial vehicle for the international distribution of products and services. However, there has long been missing a user-friendly model contract that would reflect the diversity of international franchising contracts. Because the ICC has drafted a model form of international franchising contracts, taking into account the most commonly encountered clauses in franchising agreements, their model could be used as a checklist of the core obligations of a cross-border franchise contract. Because there is no internationally agreed-upon uniform legislation on franchising, parties must rely on national laws and regulations applicable to the international franchise (when such laws and regulations exist) and should therefore very carefully draft stipulations for the legal status of the contract. This study has been intended to cite some provisions for striking a fair balance between the interests of the franchisor and those of the franchisee and for avoiding unfair trade acts in international franchising contracts.

The purpose of this parer is to examine the specifies of Institutional Arbitration and Ad Hoc Arbitration. The court prefers the institutional award in the enforcement rather than the award issued under the name of arbitrators alone. For example, the ICC Court of Arbitration scrutinizes awards for completeness, adherence to the ICC Rules and internal consistency, which since the court assurance for enforcement. In terms of arbitration costs, for which the ad hoc arbitration is considered to have comparative advantages, the institutional arbitration may not be more expensive than ad hoc arbitration, as in most commercial case, the administrative fees are insignificant. This paper suggests the standard or model arbitration clauses in institutional and ad hoc arbitrations. These Clauses contains the minimum elements necessary to render the arbitration agreement enforceable and effective. So both parties may add the specific contents such as the number of arbitrator, the place of arbitration and the language. Especially, in Ad Hoc Arbitration without designated set of rules, more clean clause for appointing arbitrators will be needed.

Background: The purpose of this study is comparison of the results between regression and multi-level analysis to find out factors influencing outcome indicators (in-hospital death, length of stay, and medical charges) of stroke patients. Methods: By using patient sample data of Health Insurance Review & Assessment Service, patients admitted with stroke were selected as survey target and 15,864 patients and 762 hospitals were surveyed. Results: For the results of existing regression analysis and multi-level analysis, models were assessed through model suitability index value and as a result, the value of results of multi-level analysis decreased compared to the results of regression, showing it is a better model. Conclusion: Factors influencing in-hospital death of stroke patients were analyzed and as a result, intra-class correlation (ICC) was 13.6%. In factors influencing length of stay, ICC was 11.4%, and medical charges, ICC was 17.7%. It was found that factors influencing the outcome indicators of stroke patients may vary in every hospital. This study could carry out more accurate analysis than existing research findings through analysis of reflecting structure at patient level and hospital level factors and analysis on random effect.

Background: The use of three-dimensional multi-segment foot models (3D MFMs) is increasing since they have superior ability to illustrate the effect of foot and ankle pathologies on intersegmental motion of the foot compared to single-segment foot model gait analysis. However, validation of the repeatability of the 3D MFMs is important for their clinical use. Although many MFMs have been validated in normal adults, research on MFM repeatability in children is lacking. The purpose of this study is to validate the intrasession, intersession, and interrater repeatability of an MFM with a 15-marker set (DuPont foot model) in healthy children. Methods: The study included 20 feet of 20 healthy children (10 boys and 10 girls). We divided the participants into two groups of 10 each. One group was tested by the same operator in each test (intersession analysis), while the other group was tested by a different operator in each test (interrater analysis). The multiple correlation coefficient (CMC) and intraclass correlation coefficient (ICC) were calculated to assess repeatability. The difference between the two sessions of each group was assessed at each time point of gait cycle. Results: The intrasession CMC and ICC values of all parameters showed excellent or very good repeatability. The intersession CMC of many parameters showed good or better repeatability. Interrater CMC and ICC values were generally lower for all parameters than intrasession and intersession. The mean gaps of all parameters were generally similar to those of the previous study. Conclusions: We demonstrated that 3D MFM using a 15-marker set had high intrasession, intersession, and interrater repeatability in the assessment of foot motion in healthy children but recommend some caution in interpreting the hindfoot parameters.

In this study, we analyze the effect on the smoking status in the Seoul Metropolitan area using a multilevel logistic model with Community Health Survey data from the Korea Centers for Disease Control and Prevention. Intraclass correlation coefficient (ICC), profiling analysis and two types of predicted value were used to determine the appropriate multilevel analysis level. Sensitivity, specificity, percentage of correctly classified observations (PCC) and ROC curve evaluated model performance. We showed the applicability for multilevel analysis allowed for the possibility that different factors contribute to within group and between group variability using survey data.

Intrahepatic cholangiocarcinoma (ICC), one of the primary liver cancers, is frequent in the northeastern part of Thailand. Surgical resection remains the best method of treatment, but patients suffering from ICC usually present at a late stage of the disease. Studies of survival and prognostic factors after surgery remain rare. The aim here was to evaluate the survival rate and factors affecting the survival of patients with intrahepatic cholangiocarcinoma after surgery. The study used a retrospective cohort design. The subjects were 73 consecutive patients with ICC, who were admitted for surgery to Srinagarind Hospital, Khon Kaen University, during the period 2005-2009. The censoring date was 31 December, 2011, data being evaluated using uni- and multivariate analyses. Postoperative survival analysis was performed by the Kaplan-Meier method, and the Cox proportional hazard model was used to identify independent prognostic factors. The total follow-up time was 99 person-years. The total number of deaths was 59, giving a mortality rate of 59 per 100 person-years. The cumulative 1-, 3-, and 5-year survival rates were 52.1%, 21.7%, and 11.2%, respectively. The median duration of survival after resection was 12.4 months. Univariate analysis revealed stage of disease, lymph node metastasis, histological type, histological grade and macroscopic classification to be statistically significant (p-value<0.05) prognostic factors. In the multivariate analysis, only macroscopic classification was statistically significant (p-value<0.05). In conclusion, macroscopic classification was the only independent factor found to be significantly associated with survival following surgical treatment of ICC.
