This study compares and analyzes the fashion industry of Korea with that of China and Japan, the two countries geographically and culturally adjacent to Korea, by applying the generalized double diamond model to find useful measures to strengthen the global competitiveness of the Korean fashion industry. The fashion industries of Korea, China and Japan were first compared in terms of the four determinants of the double diamond model: thereafter, the double diamond model of Korea, China and Japan were compared. In this, study 31 sub-variables were extracted to measure the eight determinants and secondary data were collected from selected sources between January 2013 and May 2014. The results of comparing the domestic diamond models showed that: China is considerably better than Korea and Japan in terms of demand conditions, firm strategy, organization, and competition conditions while Japan is superior in terms of demand conditions and Korea shows better related and supporting industries conditions. When comparing and analyzing the international diamond models, Japan is superior in terms of factor conditions and China has better demand conditions, while Korea has failed to lead in any of the four determinants. When comparing and analyzing the comprehensive diamond model per country, China show superior demand conditions and firm strategy, organization, and competition conditions, Japan has better factor conditions, and Korea shows superior related and supporting industries conditions.

Because of it's accessibility and the quantity of bone available, the ilium is a common donor site for autogenous cancellous, cortical, and corticocancellous grafts to the facial skeleton. Especially, the anterior iliac crest has been the traditional source of pelvic bone for autogenous bone grafting in the maxillofacial skeleton. Recently the need for large amounts of bone in some reconstructive procedures of the facial skeleton has led to the evaluation of posterior ilium. The posterior approach to the ilium is superior to the anterior approach when large quantities of cancellous bone are required for facial reconstruction. The posterior approach has the advantages of more available bone, fewer complications, less postoperative pain, less disturbance in ambulation, and a possible reduction in the length of hospitalization. As the posterior approach affords an almost unlimited amount of bone for autogenous grafting in the maxillofacial region, we feel its use is indicated when very large amounts of bone are required.

The extended transseptal approach to the mitral valve replacement has been used for 30 patients. There were 19 women and 11 men. Twenty five patients had rheumatic heart disease, 4 had degenerative valve ,and 1 had valve prolapse. Fifteen of 30 patients had other associated procedure; 10 had aortic valve replacement; 5 had tricuspid annuloplasty. There were no postoperative complications associated with the approaches, ie, no bleeding, no sinus node dysfuction, and no atrioventricular conduction disturbance. Despite division of the sinus node artery, preoperative atrial rhythms[3 sinus rhythms and 27 atrial fibrillations were not changed during postoperative period. The extended transseptal approach provides good mitral valve exposure without inherent complications, and is superior to that of standard approach, so we use it routinely for mitral valve procedure.

Computer vision-based human activity recognition (HAR) has become very famous these days due to its applications in various fields such as smart home healthcare for elderly people. A video-based activity recognition system basically has many goals such as to react based on people's behavior that allows the systems to proactively assist them with their tasks. A novel approach is proposed in this work for depth video based human activity recognition using joint-based motion features of depth body shapes and Deep Belief Network (DBN). From depth video, different body parts of human activities are segmented first by means of a trained random forest. The motion features representing the magnitude and direction of each joint in next frame are extracted. Finally, the features are applied for training a DBN to be used for recognition later. The proposed HAR approach showed superior performance over conventional approaches on private and public datasets, indicating a prominent approach for practical applications in smartly controlled environments.

The survival rate after resectional operation for carcinoma of the esophagus is still very low and many factors contribute to these poor results. We analyze the clinical results of 56 operated patients among 62 esophageal cancer patients between March, 1974 and July, 1988. Among the 62 patients, 52 patients were squamous cell carcinoma and 8 were adenocarcinoma, one was leiomyosarcoma and one was adenosquamous cell carcinoma. The classification of esophageal cancer was based on TNM classification of American Joint Committee on cancer". Among the operated patients, stage I was 5[9.6%], stage II was 13[25%], stage III was 26[50%], stage IV was 8[15.4%]. And its one year survival rate was 80%, 69%, 11.5%, 0% for each stages. The rate of resectability was 30.3% and resection of esophagus with esophagogastrostomy and extended lymph node dissection was performed on 17 patients without distant metastasis or adjacent organ invasion. Substernal esophago-colono-gastrostomy, Celestine tube insertion and feeding gastrostomy was performed on remained 39 patients. The analysis of postoperative survival duration revealed the superiority of esophagectomy with extended lymph node dissection over other palliative operation. [1 year survival rate: 79% versus 21%] We concluded that the survival rate of esophageal resection with lymph node dissection group was superior to nonresective palliative operation group. And transthoracic approach was superior to extrathoracic approach in involved lymph node dissection and esophageal resection in locally invaded cases.ases.

The optimal power flow (OPF) problem was introduced by Carpentier in 1962 as a network constrained economic dispatch problem. Since then, it has been intensively studied and widely used in power system operation and planning. In the past few decades, many stochastic optimization methods such as Genetic Algorithm (GA), Evolutionary Programming (EP), and Particle Swarm Optimization (PSO) have been applied to solve the OPF problem. In particular, PSO is a newly proposed population based stochastic optimization algorithm. The main idea behind it is based on the food-searching behavior of birds and fish. Compared with other stochastic optimization methods, PSO has comparable or even superior search performance for some hard optimization problems in real power systems. Nowadays, some modifications such as breeding and selection operators are considered to make the PSO superior and robust. In this paper, we propose the Modified PSO (MPSO), in which the mutation operator of GA is incorporated into the conventional PSO to improve the search performance. To verify the optimal solution searching ability, the proposed approach has been evaluated on an IEEE 3D-bus test system. The results showed that performance of the proposed approach is better than that of the standard PSO.

Superior sulcus or pancoase tumor refers to any primarty lung cancer locating in thoracic inlet and causing pain in the periscapular region or aim. These originate inperipheral, and involve th extrapulmonary structures more than parenchyma of the lung. We experienced l case of superior sulcus tumor radically resected via anterior transcervical approach, which provide more safe exposure of cervical structures of thoracic inlet than classis posterolateral thoracotomy. Therefore were report this case with review of literature.

The purpose of this study was to examine the issues involved in offering superior customer experience on fashion retail stores in Brazil. The approach used to access CEM (Customer Experience Management) issues was a special questionnaire with 23 questions, through a research with managers of three important brazilian fashion retail chains (focused on class A clients). Some statistical techniques were used for data processing. It was possible to analyze the aspects that impact on the customer experience and their relevance. it was possible to realize that CEM is effective in increasing productivity and, so, it can be used as a guideline matrix management in decision making to promote superior customer experiences. The classical management is usually conservative and avoids to deal with strategies that do not necessarily involve numbers. Dealing with intangible and so subtle experience is unusual and a huge challenge, but sometimes it is necessary to look beyond the obvious and accessible statistics. If CEM is a strategy to focus on operations and processes of a business around the customers experiences with the company, it is essential to structure it and find out its effectiveness.

An effective approach to promoting sustainability within the construction industry is the use of recycled aggregate concrete (RAC) as a substitute for natural aggregates. Ensuring the frost resilience of RAC technologies is crucial to facilitate their adoption in regions characterized by cold temperatures. The main aim of this study was to use the Random Forests (RF) approach to forecast the frost durability of RAC in cold locations, with a focus on the durability factor (DF) value. Herein, three optimization algorithms named Sine-cosine optimization algorithm (SCA), Black widow optimization algorithm (BWOA), and Equilibrium optimizer (EO) were considered for determing optimal values of RF hyperparameters. The findings show that all developed systems faithfully represented the DF, with an R² for the train and test data phases of better than 0.9539 and 0.9777, respectively. In two assessment and learning stages, EO - RF is found to be superior than BWOA - RF and SCA - RF. The outperformed model's performance (EO - RF) was superior to that of ANN (from literature) by raising the values of R² and reducing the RMSE values. Considering the justifications, as well as the comparisons from metrics and Taylor diagram's findings, it could be found out that, although other RF models were equally reliable in predicting the the frost durability of RAC based on the durability factor (DF) value in cold climates, the developed EO - RF strategy excelled them all.
