Without exception, diverse LULU(Locally Unwanted Land Use) facilities have been under the location conflict, especially between the public government units and local residents. In spite of repeated trials-and-errors, literally, the location conflict has shown no sign of improvement over time in Korea. As practical means to tackle these issues, this study focuses on divulging explicit and implicit relationships among key factors derived from the location conflict on the LULU facilities. Here, major research variables cover residents' agreement, residents' perception, compensation expectation, and public opinion. As the location conflict on the LULU facilities could be strengthened or resolved by the dynamic feedback system, it applies basic tools geared toward causal loop diagramming. After repeated experiments, the study highlights the fact that the residents' perception, compensation expectation, and public opinion, individually and collectively, exert significant impact on the residents' agreement ratio.

Under the competitive environment of shipping industry, the improvement of the quality of shipping service could be one of the most important factors to be considered in the recent shipping industry. However, there has been little study on the clear concept of the service quality in the shipping so far. The subject of this study is to define the concept of the service quality in the shipping by way of making investigation into the related precedent literatures studied. The quality of service is recognized in general as a degree of gap between the customer's expectation and the perception. Therefore the service quality of shipping could be measured by evaluating the gaps between shipper's expectation and performance of shipping service. If the determinants of the service quality in the shipping are proved, and the discrepancies of expectations and perception between the shipping company and the shipper could be clarified, such a result would be an useful help to establish marketing strategy.

This paper investigates the use of the inverse-free sparse Bayesian learning (SBL) approach for peak-to-average power ratio (PAPR) reduction in orthogonal frequency-division multiplexing (OFDM)-based multiuser massive multiple-input multiple-output (MIMO) systems. The Bayesian inference method employs a truncated Gaussian mixture prior for the sought-after low-PAPR signal. To learn the prior signal, associated hyperparameters and underlying statistical parameters, we use the variational expectation-maximization (EM) iterative algorithm. The matrix inversion involved in the expectation step (E-step) is averted by invoking a relaxed evidence lower bound (relaxed-ELBO). The resulting inverse-free SBL algorithm has a much lower complexity than the standard SBL algorithm. Numerical experiments confirm the substantial improvement over existing methods in terms of PAPR reduction for different MIMO configurations.

The purpose of this study was to measure patients satisfaction and expectation with hospital foodservices, and thereby identify areas for improvement and provide basic data for the introduction of total quality management with hospital foodservices. This survey was carried out on 383 hospitalized patients of 7 hospitals in Deagu, Busan, Changwon with 350 beds to determine the quality satisfaction with foodservices. The subjects were 50.5% male and 49.5% female. 62.6% of the subjects were over 40 age, 31.4% were only educated to middle school or below, 28.3% were hospitalized for 7-14 days. The mean score for taste of diet was 2.79, temperature 3.23, appearances 2.96. Most subjects agreed with following foodservice characteristics that meals of movement (4.03), dress of employees (3.84), kindness of employees and meals arrived exactly the same time every day (3.47) and cleanliness of foods (3.34) and dishes (3.33). The unsatisfied quality attributies were information provide (2.82), variety of the meals (2.91), mixing of meals (2.95), the opportunity to meet with a dietitian (2.97) and prompt dealings with meal complaints (3.01). Most subjects expectation that the decrease the multiple of menus, increase provide of fruits in hospital meals and selective menus in hospital foodservices operations. In conclusion, it would seem to be desirable that hospital foodservices departments introduce selective menus, quality assurance, and increase the meal rounding of dietitians in the patient foodservice.

The Landscape Act was enacted in 2007 introducing a new procedure of the Local Landscape Agreement and the Local Landscape Improvement Projects. The act has granted local governments a legal basis to support residents participation activities in order to create, improve, and maintain the townscape quality of their neighborhood environments. The degree of utilization of this particular process, however, is far below the expectation. Partly, it is due to the lack of field experience and concrete guidelines for preparation and implementation in actual landscape planning process. This study aims to seek for detailed solution to lead the residents participation for local landscape improvement in Korea through consideration for institutional strategies and cases about the local landscape planning and management in Japan. Local landscape improvement projects in Japan are progressing successfully in concurrence with a variety of local participants such as residents participation, administrative supporting and supporting of local company. And it will be possible to support systematically with systematization of participants, such as NPO and a council.
