Purpose: The aim of this study was to analyze the oncologic outcomes and the risk factors for recurrence after a tumor-specific mesorectal excision (TSME) of resectable rectal cancer in a single institution. Methods: A total of 782 patients who underwent a TSME for resectable rectal cancer between February 1995 and December 2005 were enrolled retrospectively. Oncologic outcomes included 5-year cancer-specific survival and its affecting factors,as well as risk factors for local and systemic recurrence. Results: The 5-year cancer-specific survival rate was 77.53% with a mean follow-up period of 61 ± 31 months. The overall local and systemic recurrence rates were 9.2% and 21.1%, respectively. The risk factors for local recurrence were pN stage (P = 0.015), positive distal resection margin, and positive circumferential resection margin (P < 0.001). The risk factors for systemic recurrence were pN stage (P < 0.001) and preoperative carcinoembryonic antigen level (P = 0.005). The prognostic factors for cancer-specific survival were pT stage (P < 0.001), pN stage (P < 0.001), positive distal resection margin (P =0.005), and positive circumferential resection margin (P = 0.016). Conclusion: The oncologic outcomes in our institution after a TSME for patients with resectable rectal cancer were similar to those reported in other recent studies, and we established the risk factors that could be crucial for the planning of treatment and follow-up.

In recent years, work to improve the power of a tractor has been in development. This study, using the mid-PTO power of a compact tractor, attempted to develop a high-speed mid-mower by setting the rotation to more than 3,000 RPM designed/manufactured major components of the high speed mid-mower. The performance of high-speed mid-mower was evaluated by the precision of straight bevel gears, and durability, the noise of the gearbox, the gearbox internal temperature, the maximum rotation speed of the mid-mowers, and the grass cutting test. Through the performance test results, the maximum number of revolutions of the mid-mower was measured over 3,000RPM, the gearbox noise and gearbox internal temperature satisfied the performance requirements of a high speed mid-mower.

Trust is advocated as the single most important factor for consumers choosing an supplier. To study trust mechanisms underlying consumer-e-retailer exchange relationship. this research takes a new perspective, a perspective directed toward customer retention By bring together three divers approaches-trust literature, global evaluation theory, and transaction costs analysis, this study develops an integrative model of consumer trust in an e-retailer Hypotheses was tested using structural equation modeling, multiple regression analysis, and multiple group analysis Finding of the study imply that consumer trust in an e-retailer derives not only from a consumer's web experience but also from his/her experience outside the web Specifically, a consumer's attitudes toward the key components of his/her entire online purchase experience(ie, website design, fulfillment/reliability, privacy/security, and customer service) constitute the key drivers of consumer trust Findings also indicate that trust is intrinsically beneficial. If a consumer trusts an e-retailer, he/she will come back in the future or even become loyal to the e-retailer Further, findings suggest that though trust has a direct effect on future intentions and loyalty, part of its effect is conditional on its ability to a reduce transaction costs, Additionally, findings of the study imply that as contextual factors, consumer dependence on an e-retailer confounds the effects of trust on future intentions and loyalty, and uncertainty surrounding online transacting environments moderates the effect of trust on future intentions, However, environmental u/ncertainty was not found to confound the effect of trust on loyalty

This research was conducted focusing on small and medium lodging industry classified as the lodging industry out of the hospitality industry. Indeed, efficient and effective distribution for maximization of limited resources is not made in small and medium lodging due to a lack of material and human resources. They do not figure not factors of service quality that affect perceived service quality and overall service quality in detail. In addition, they have different characteristics from hotels, but they are indiscriminately applying existing researches targeting the hotel industry to the small and medium lodging industry. To survive in a fierce competitive environment, they should come up with realistic and concrete measures and strategies that can enhance customers` perceived service quality and customer loyalty by maximizing limited resources. As shown in this study, since small and medium lodging find it hard to provide full service, they should provide intangible service quality in a way to distribute resources and to minimize costs by more considering tangible aspects of service. It has significance in having implications for marketing strategy that can enhance management performance and customer retention along with cost reduction.

Recently, the work machine is widely used in the agricultural machine and to use the power source of the tractor, the mower had been widely used as a working machine for mowing. The mower is classified as a front mower, mid-mower, and rear mower according to the mounting position of the lower frame on tractor. The main structure of mower is composed of deck, gearbox, and blade. This study concerns a study on air flow characteristics of Mid-mower for tractor. An air flow characteristics of the Mid-mower deck was evaluated by the velocity vector, flow path, and total air flow according to the number of revolutions. As the analysis results, The inner path of designed deck had no effect on air flow.

Happiness means a state in which humans feel sufficient satisfaction and joy in the life they live in, and all humans want to be happy. For the qualitative growth of the restaurant industry, the happiness of restaurant owners must be premised, and in order for restaurant owners to be happy, they must be satisfied personally as well as professionally, environmentally, and institutionally. In order or restaurant owners to take a step further into the happy restaurant industry and for small business owners to grow into a strong country, it is necessary to periodically measure the happiness of restaurant owners. According to the scale development methodology, the restaurant owner happiness index scale composed of 8 dimensions and 47 measurement tools was developed, an AHP survey and analysis were conducted to calculate the weight of the developed restaurant owner happiness index dimensions, and an arithmetic equation was established to convert happiness into a score. In addition, as a result of verifying the validity and reliability of the measurement tool, both were found to meet the criteria, indicating that validity and reliability were secured. This study provided academic implications through the development of the happiness index for restaurants and practical implications for the actual use and application of the happiness index for restaurants, and presented limitations due to the characteristics of the restaurant industry and future research tasks through actual happiness measurement.
