This research is to explore food waste management across local governments. In particular, pubic administration on food waste, food waste management (from generation to disposal) and civil complaints in jurisdiction are examined. In doing so, a self-administered questionnaire survey was conducted among civil officers in charge of food waste management, and all the collected responses were statistically analyzed. The main results were as follows: public spending on food waste management was a little larger in metropolises than in provincial cities, and the largest food waste source was identified as households (in housing). While regular collection of food waste by trucks was the most common transport method adopted by local governments, resource recovery for compost/fertilizer production was widely used. Also, most of the respondents agreed that the current approach to food waste handling practices are necessarily replaced with more advanced technology converting waste into energy or fuel. Further, it's found that the civil complaints on food waste management were largely categorized into 3 groups - food waste handling, civil service and food waste retrieval. Therefore, the findings indicate that the development and application of no-food waste or waste-to-resource systems are effective in housing estates where large amount of food waste is generated and eliminated.

To enhance the user response time of content-based retrieval service for multimedia information, several multi-dimensional index schemes have been proposed. M-tree, a well-known multidimensional index scheme is of metric space access method, and is based on the distance between objects in the metric space. However, since the overlap between index spaces of nodes might enlarge the number of nodes of M-tree accessed for query processing, the user response time for content-based multimedia information retrieval grows longer. In this paper, we propose a node split algorithm which is able to reduce the sire of overlap between index spaces of nodes in M-tree. In the proposed scheme, we choose a virtual center point as the routing object and entry redistribution as the postprocessing after node split in order to reduce the radius of index space of a node, and finally in order to reduce the overlap between the index spaces of routing nodes. From the experimental results, we can see the proposed split algorithm reduce the overlap between index space of nodes and finally enhance the user response time for similarity-based query processing.

With a rapidly increasing number of foreign patients in Korea, it is necessary to manage and enhance the quality of nursing care for foreign inpatients through the promotion of studies on practical nursing care experience. This study is a qualitative study conducted to understand and describe the care experiences of nurses responsible for non-English speaking foreign inpatients. There were 10 nurses with a clinical career of more than two years included in this study for analysis. Data were collected through in-depth individual interviews and analyzed using qualitative content analysis. Five themes emerged from the analysis. 'Aware of cultural differences', 'establish trusting relationships through all my heart', 'additional nursing task', 'empathy for genuine nursing', 'sorriness and relieved'. The results of this study provided the understanding on the experiences of nurses, who do not speak English, but still responsible for providing care to foreign inpatients. Despite the language barrier, cultural differences, and work overload, nurses caring for foreign patients struggled with authenticity in nursing. On the other hand, as there was a lack of system resources, such as manuals and training materials in various languages other than English, institutions should put forth greater effort and resources to be prepared to care for foreign inpatients.

The purpose of this study is to investigate the knowledge and recognition about blood donation and satisfaction, look for ways to promote the idea that effective, was trying to get the plan to provide the basis for the expanding population of voluntary and continuous blood donation. A survey was from May 9, 2012 to May 24, 2012 and total 636 copies were used as final study data. The data collected analyzed with SPSS win 21.0 using descriptive methods, frequency analysis, chi-square test, t-test, ANOVA. The results were as follows. First, the rates of the blood donors were higher in the men, in the age group from 20 to 29, in the students and in the group that received college or higher education. Second, as for the knowledge and recognition of the blood donors on blood donation, many replied they didn't know well about it. Concerning satisfaction level, they gave higher marks to satisfaction with related service than with blood donation itself. Third, the necessity of sustained blood donation promotion and education was pointed out. TV was most preferred, followed by ads on the street and ads on the subway. To expedite an increase in the blood-doner population, prolonged education and promotion are required to change the way that people in general look at blood donation, and a variety of rewards should be provided for blood donors.

Objective : The purpose of this article is to study the effectiveness of a group occupational therapy for children via systematic review, and to provide clinical evidences. Methods : The systematic review initially included articles in Pubmed, Ovid, RISS, KISS, and DBpia, published until 2014. Total 14 articles have been chosen, using different keyword of each domestic/foreign studies. Selected articles were divided depending on the level of evidence, and eventually been organized into group PICO (Patient, Intervention, Comparison, Outcome). Results : The results indicated that there are more diagnosed children than normal in participants and especially children with sensory integration disorder (28.6%) appeared to be the most common. In intervention, group sensory integrative intervention had the largest frequency, and instruments measuring social skills were used most for analyzing the intervention results. The effectiveness of interventions showing statistically significant results were 40.7% of Total. Conclusion : Group occupational therapy for children should be provided to various diagnosis with widely better quality of interventions providing the enough support for the evidence level.

The purpose of this study aims to analyse the case on the violation of the Agreement on WTO-TRIMs in the China with auto parts case. The Agreement on Trade Related Investment Measures(TRIMs) are rules that apply to the domestic regulations, a country applies to foreign investors, often as part of an industrial policy. The agreement was agreed upon by all members of the WTO. The TRIMs Agreement bans any laws, policies or administrative regulations favouring domestic products. This includes government incentives to encourage corporations to use domestically made products as a way of creating or protecting local jobs. The Agreement on TRIMs is only one such restriction within the broader WTO regime. Policies such as local content requirements and trade balancing rules that have traditionally been used to both promote the interests of domestic industries and combat restrictive business practices are now banned. In many ways the Agreement on WTO-TRIMs is less significant than the WTO agreements on services, etc. The TRIMs Agreement does not involve any new rules or disciplines, referring only to the existing provisions under the GATT. However, by enforcing GATT provisions on 'national treatment', this short and simple agreement has had farreaching effects on auto parts, etc. Meanwhile, China has been members of the WTO late 2001, once the measures imposed high-rate tariff for import parts was intended to regulate importer of auto parts in order to avoid the high-rate tariff.

The regulation of media concentration which is provided in the German Interstate Treaty on Broadcasting (RStV) is part of the rules forming the "positive broadcasting order" required by German Constitutional Law. This control ensures that the diversity of viewpoints can be articulated to the public. Broadcasting must operate independently from the state and from particular social groups if it is to be a genuine service to the public. One risk of economic competition in the media is a tendency towards the concentration of business enterprises. Moreover, economic competition is no guarantee for journalistic diversity. The aim of balanced diversity in the broadcasting sector can only be pursued by creating conditions under which different voices obtain the chance to be heard in an equitable manner. Within the framework of the meaning of section 26, it shall be assumed that there is a predominant impact on public opinion if the programs attributable to one company reach an annual audience share of 30 percent. The same shall apply if the company reaches an audience share of 25 percent and holds a dominant position in a related media-market or an overall assessment of its activities in television. The restriction of audience shares has limits such as that the audience shares of news programs and education and entertainment programs are pooled. Therefore, there is a vagueness about the productivity of different program branches.

The World Wide Web has become one of the major services provided through Internet. When searching the vast web space, users use bookmarking facilities to record the sites of interests encountered during the course of navigation. One of the typical problems arising from bookmarking is that the list of bookmarks lose coherent organization when the the becomes too lengthy, thus ceasing to function as a practical finding aid. In order to maintain the bookmark file in an efficient, organized manner, the user has to classify all the bookmarks newly added to the file, and update the folders. This paper introduces our learning agent called BClassifier that automatically classifies bookmarks by analyzing the contents of the corresponding web documents. The chief source for the training examples are the bookmarks already classified into several bookmark folders according to their subject by the user. Additionally, the web pages found under top categories of Yahoo site are collected and included in the training examples for diversifying the subject categories to be represented, and the training examples for these categories as well. Our agent employs naive Bayesian learning method that is a well-tested, probability-based categorizing technique. In this paper, the outcome of some experimentation is also outlined and evaluated. A comparison of naive Bayesian learning method alongside other learning methods such as k-Nearest Neighbor and TFIDF is also presented.
