Urban forest area in South Korea has been increased up to 20.8% of national land as of 2007 by the mergence of municipalities and counties. The rate of park and green tract among urban forest averages out to about 4% nationally but the Capital, Seoul, almost 105% level, not easy to split the two. Park and green has positive management system because of its infrastructure attribute and relevant security obligation standard while urban forest left alone with no such concerns. The most important reason of the negligence comes from institutional inertia although it is possible to be managed functionally by forest laws as like forests of park, landscape, wind and noise protection, and timber product. As a results, it reaches below than 92.64% of the national average level of the timber stockpile especially in the metropolitan areas and loses broad acres rapidly due to the easy conversion system to the urban land usage. Therefore, there must be required some alternative methodologies to conserve and foster it. The paper proposes the four urban forest management types and their control methods. The four types divide into conservation, foster, development, and reservation ones. Also it suggests the five furtherance tract types with the combination among the four earlier types, optionally having one of the six aim climaxes and recommends the standardization of operation design. The total green quantity index of urban forest also suggested by the weight method according to location and DBH class. The case study of the suggested model was executed on the Daejon Metropolitan area and its index calculated as 110.4% level compared with the acreage.

This study was designed to develop the strategy plans for the customer satisfaction on foodservice in the senior care facilities. For this, we examined the level of the customer satisfaction and foodservice quality. Additionally, the association between service quality, customer satisfaction, and social, psychological, physical factors of the aged were tested. Data from convenience samples from 3 senior care facilities were collected by using a questionnaire. Exploratory factor analyses were completed on 20 attributes for the food and service quality and 7 items for the social and psychological states of the aged, respectively. Cronbach's a was estimated for reliability, and Pearson correlation and multiple regression analysis were used for statistical analyses. The level of the satisfaction on foodservice was 4.01 of 5.0. The satisfaction on foodservice did not show the significant differences by gender, education level, BMI, and socio-psychological satisfaction. But the foodservice quality and the satisfaction showed significant difference by income and physical problem, and the goal of life of the eldely, respectively. Multiple regression analyses revealed that the determinants of the customer satisfaction on foodservice were the core quality of product, confidence, professionalism of employees and secondary quality of products. Especially, the kindness of employee is the most important attribute of the foodservice. Based on these results, we can set the strategy plans as follow: (1) the introduction of the foodservice evaluation system (2) the deployment of the event activities for offering fun to the customer (3) the continuous training of employees for ensuring the professional and kind service system, and (4) the introduction of selective menu system and take-out service of menu.

We report the results of our analysis of far ultraviolet (FUV) observations made for the broad region around the ${\alpha}$ Vir (Spica) including the interaction zone of the Loop I and the Local Bubble. We employed the datasets of the GALEX and the FIMS, which made observations at similar FUV wavelengths. First, we noted that the GALEX image was enhanced in the southern region where the interaction zone exists. We attribute this enhanced FUV emission to dust scattering of the stellar photons, mostly from the background field stars with small contributions from the central star Spica. While the region is optically thin in general, the FUV intensity did not correlate well with the dust extinction level, indicating that the local radiation field has significant fluctuations. On the other hand, the GALEX FUV intensity well with the $H{\alpha}$ intensity as well as the dust extinction level in the northern part. In fact, the neutral hydrogen column density correlated very well with the dust extinction level throughout the whole region in consideration. The relationship between the neutral hydrogen column density and the color excess was estimated to be ${\sim}7{\times}10^{21}atoms\;cm^{-2}$, which is a little higher than the previous observations made for a diffuse interstellar medium. The spectral analyses of the FIMS observations showed the enhanced C IV emission throughout the whole region, indicating that the C IV emission arises by the interaction of the hot gases with the shell boundaries. A simple model showed that a large portion of the C IV emission comes from the Loop I side of the interaction zone, compared to the Local Bubble side. The FIMS spectrum also showed indications of the molecular hydrogen fluorescence lines for the interaction zone.

This paper provides data for product development and improvement of grape varieties by analyzing the satisfaction-importance of the grape selection attributes from a consumer's perspective. A survey was conducted on consumers aged 19-59 living in Seoul, Gyeonggi and Incheon on their fruit consumption level, preferences according to the grape quality characteristics, importance, and satisfaction with the grape selection attributes. Three hundred and eighty two valid samples were collected and analyzed statistically using SPSS 23. In the preference according to the grape quality characteristics, consumers tended to prefer a sweet taste, black color, and seedless grapes. Regarding the importance of the grape selection attributes according to the level of grape consumption, the high consumption group considers texture, size, shape, color, ease of removing seeds, country of origin, area of production, certification, and brand to be more important. In satisfaction, the high consumption group rated satisfaction highly in texture, odor, size, shape, color, ease of removing peelings, ease of removing seeds, price, country of origin, area of production, certification, and brand. An analysis of the IPA of the grape selection attributes showed that improvement of price and shape attributes will be prioritized, and the development and management of properties, such as seeds, peelings, certification, and brand will be required. These results can be used to help improve the grape varieties and develop products that meet the consumer needs, secure the competitiveness of grape farmers, and revitalize the local economy.

Purpose - The Service Level Agreement which has been used in the IT information communication industry to maintain the level of service supplied by a vendor has been adopted in the service industry surrounding the airliners and airports. Considering that service quality is dependent on attitude of employees who are responsible to provide service, it is very important to understand what kinds of effects SLA(service level agreement) has on the attitude when SLA is applied to the service industry. SLA is an agreement between management authority and service providing contractor to make sure that certain level of service quality should be provided. For employees whose responsibilities are providing the service, SLA has both positive effects and negative effects. Negative side is that employees have to follow many irrigating complicated rules. On the other hand, the attribute of rules is that once one is become accustomed to them one may feel comfortable doing repeated same kinds of works, which is positive side for the workers. Research design, data, and methodology - We analyzed whether the SLA has moderating effects while service providers' job environment of outsourcing companies affects job satisfaction. Especially in the service industry, job satisfaction has great effects on productivity and efficiency. Results - The study results show the following. First, SLA has moderating effects while task performance environment affects treatment satisfaction. Second, SLA has moderating effects while task motivation environment affects treatment satisfaction. Third, SLA has moderating effects while physical work environment satisfaction affects treatment satisfaction. Fourth, on the other hand, the difficulties caused by SLA have moderating effects while the relationship among employees affects job dissatisfaction, which is negative side of SLA. From these results, we can tell that SLA has more positive moderating effects on treatment satisfaction on the whole. which results can be used to justify applying SLA to the service industry. Conclusions - In this study we analyzed the effects of SLA which have become more important in service industry nowadays on service providing employees. For managing side, the positive effects of SLA have to be emphasized while the negative effects should be avoided or minimized.

The credit rating represents an assessment of the relative level of risk associated with the timely payments required by the debt obligation. In this paper, we present a new approach to credit rating of customers based on the rough set theory. The concept of a rough set appeared to be an effective tool for the analysis of customer information systems representing knowledge gained by experience. The customer information system describes a set of customers by a set of multi-valued attributes, called condition attributes. The customers are classified into groups of risk subject to an expert's opinion, called decision attribute. A natural problem of knowledge analysis consists then in discovering relationships, in terms of decision rules, between description of customers by condition attributes and particular decisions. The rough set approach enables one to discover minimal subsets of condition attributes ensuring an acceptable quality of classification of the customers analyzed and to derive decision rules from the customer information system which can be used to support decisions about rating new customers. Using the rough set approach one analyses only facts hidden in data, it does not need any additional information about data and does not correct inconsistencies manifested in data; instead, rules produced are categorized into certain and possible. A real problem of the evaluation of the evaluation of credit rating by a department store is studied using the rough set approach.
