A more efficient use of nutrients can benefit both farmers and water quality. To propose an establishment scheme for official standards for liquid fertilizer from swine manure slurry, we evaluated previous and present data related to swine manure as well as analyzed 101 swine manure samples collected from 28 public livestock recycling centers throughout the nation. From these investigations, we found that the official standards for byproduct fertilizers set by the Rural Development Administration (RDA), especially for a liquid swine manure fertilizer, should be revised due to nutrient content requirements having to meet at least 0.3% content for the sum of nitrogen, phosphorus, and potassium. Otherwise, most of the swine manure cannot be utilized as a liquid fertilizer because the result of the 101 samples' analysis showed fewer than 28% of them met the minimum standard of ${\geq}0.3%$ content for the sum of nitrogen, phosphorus, and potassium, while the contents of heavy metals as indicators of toxicity met the standard requirements. Therefore, it is suggested that official standards for byproduct fertilizers set by RDA should be revised as follows: no limit for nutrient contents and addition of chloride as homogeneity. Also, NaCl should be changed to Na because NaCl cannot be analyzed by instrument.

Project owner, asbestos removal specialist, experts on asbestos removal work, as counter parts to be defined in the study to make out research goals have been asked with questionnaire survey and replied with 65, 275, 32 cases, respectively. And additionally, direct interview 73 sheets have been collected to find out current status of required engineers and equipments assigned and provided to the field, from them, three(3) concerned parties. Questionnaire subjects are composed of common items, reasonable unit cost, need of separate contract-awarding system, status of performing standard contract, status of providing legal engineers and equipments. Concentrated review of two~three questions by subject has been made to find out and compare idea results between three(3) concerned parties. First, legal and practical work status survey have been made to determine reasonability of introducing separate contract-awarding system, as a part of ensuring reasonable unit work cost. And then, two different status have been compared and there is introduction possibility of separate contract-awarding system, it is found out. The possibility of separate contract also has been confirmed by comparison of domestic legal grounds. Justificating grounds to introduce separate contract-awarding system have been shown. Standard contract status between asbestos removal specialists has been compared using two cases of providing removal work contract and receiving it. It is shown that case of 50 percent or less contains 38.5% when they receive contract, but only 10 percent reduction of original contract amount has been made when they provide it. It means that asbestos removal specialists do not keep occupational safety and health regulations.

This study is intended to investigate if the standard of vocational rehabilitation service could be solely determined by medical standard for disability definement and to find out what alternatives are available to resolve practical problems for those who are not identified as the severely disabled by the disability definement but do experience severe handicaps at work. Through the literature review, the researcher argued that the concept of 'functional limitation' would be a criteria, and thereby applied Modified Barthel Index to measure the degree of functional limitation. In view of researching the relationship among physical impairment, functional limitation, and job status based on 381 cerebral palsied, variables such as the type of cerebral palsy and the part of paralysis, have neither direct nor indirect influence to the job status; however, the pain and the mobility have indirect effects, and the ability of self-management has direct effect on the job status. The researcher concluded that future research about disabilities needs to provide a serious thought on what it is to be defined as 'disabilities', as well as to focus on further research conceptualizing the degree of physical 'functional limitation'.

Objectives : The aim of the study is to draw a consensus in acupuncture point locations (APLs) which are frequently used in experimental animal studies. Well-documented APL is needed not only for human but also for rodents because stimulation of precise point is very important factor in acupuncture. Methods : We organized a committee with experts to reach a consensus on the APLs in rat. The subject points were limited to 22 points used in the papers published at international peer-review journals. To describe point locations, we adopted the syntax of sentence used in the WHO standard acupuncture point locations. Results : Locations of 22 acupuncture points such as ST36, LI4, PC6, and SP6 were described in English with photographic illustrations. Interestingly, we found that ST36 had been inserted into 2 different locations in rodent. Under consideration of practical use, the location of ST36 point was described in 2 different ways. Conclusion : We hope that newly developed APLs would be a good indicator of acupuncture experiments in rats and mice.

Purpose: According to the trend of the global burden of disease, in the future our society is expected to face with gradually increasing problems related to mental health and the demand for the various types of quality mental health facilities. This study investigates whether the accreditation of Mental health facilities serves as a building evaluation tool, and contribute to environmental welfare of the mentally ill. Methods: The facility assessment items related to architectural design are extracted through the analysis about the accreditation program of KOIHA. Extracted items should review if they comply with the relevant regulations, and establish building design standard. Results: This study shows that the accreditation of KOIHA can certify psychiatric hospitals meet the legal requirements, the minimum standard of facilities. But it is not the evaluation of environmental quality. It is difficult to assess the quality of facility in terms of architectural design, because it has no specific standards or the level of assessment. Implications: The accreditation for mental health facilities should be able to provide the right and opportunity to choose a more quality facility for the customer. The introduction of a certification system for the evaluation of environmental quality is required in order to overcome the limitations of the accreditation of KOIHA. Development of design guidelines for mental health facilities that are the basis for certification should be also followed.

Android provides a message-passing mechanism called intent. While it helps easy developments of communications between intra and inter applications, it can be vulnerable to attacks. In particular, implicit intent, differing from explicit intent specifying a receiving component, does not specify a component that receives a message and insecure ways of using implicit intents may allow malicious applications to intercept or forge intents. In this paper, we focus on security vulnerabilities of implicit intent and review researched attacks and solutions. For the case of implicit intent using 'developer-created action', specific attacks and solutions have been published. However, for the case of implicit intent using 'Android standard action', no specific attack has been found and less studied. In this paper, we present a new attack on implicit intent using Android standard action and propose solutions to protect smart phones from this attack.

As social standards have been subdivided and specialized due to social development, the number of related laws has also increased gradually, resulting in problems of duplication or conflict within the laws. After collecting all the safety standards that exist in Korea's legislation, it is necessary to analyze the characteristics of safety standards to find duplicate or conflicting issues. In this study, the characteristics of safety standards were divided into structural parts and lexical parts by extracting common elements that appear in all safety standards and singular points that appear only in specific safety standards. As a result of the analysis, two structural properties of safety standard were found and four lexical features were derived. The impact of these characteristics on future systems for managing safety standards was also reviewed. Based on this study, when more structural and lexical features of safety standards are accumulated in the future, it is possible to develop efficient algorithms to collect and analyze safety standards, which will help solve the problem of duplication and conflict of safety standards in the law.

Many enterprises have been adopting management systems good enough for them and operating the schemes to have competitive edge better than their competitor. One of the finest systems that most companies have been selecting is ISO 14001. ISO 14001, environment management system, is widely known as advancing internal efficiency and productivity in the various industries. As a result, the number of companies that have adopted ISO 14001's certification have been increasing continuously year by year since ISO 14000 standard was called in 1994s from ISO 18000 standard that originally used. The purpose of this study is to present that ISO 14001's requirement execution influences on management performance in the small manufacturer. In order to carry out this research, we obtained 96 survey sheets and inspected ten assumptions based on the reliability, validity of the questionnaires. The results of regression analysis are summarized as follows; First, the three factors of ISO 14001 requirement, plan, implementation and operation and management consideration, have an important effect on the operational performance. Second, the three elements of ISO 14001 requirement, environment policy, implementation and operation and management consideration, affect to the financial performance significantly. Based on the results, it is sure that the companies that execute the factors of implementation and operation and management policy have a good performance to achieve operational and financial performance so that it is important to clarify the member's role, authority and follow the procedure by a company's process. Also, the truth shows CEO's continuous will and periodical review of ISO 14001 influence on management performance as well.

Objectives: The purpose of this study is to demonstrate Heart Rate Variability characteristics of menopausal patients with insomnia. Methods: From March 1, 2014 to June 20, 2017, Heart Rate Variability was measured in 102 menopausal patients who visited Cheonan Korean Medicine Hospital of Daejeon University. We compared accompanying symptoms and Heart Rate Variability values depending on sleep quality in menopausal women. Results: The accompanying symptoms of menopausal patients were as follows: hot flushes (45.1%), tiredness (25.49%), chest discomfort and palpitations (23.53%), headache (17.65%), arthralgia and muscular pain (17.65%), cold sensitivity of hands and feet (15.69%), urinary frequency (14.71%) and anxiety (10.78%). The frequency of chest discomfort and palpitation was significantly higher in the menopausal insomnia group than in normal sleep group. Comparing Heart Rate Variability between two groups, Standard deviation of the NN interval (SDNN), Total Power (TP), and Low Frequency (LF) values were significantly lower in insomnia group. Conclusions: Chest discomfort and palpitations were more frequent in insomnia patients in menopausal women than normal sleep group, and Standard deviation of the NN interval (SDNN), Total Power (TP), Low Frequency (LF) were significantly lower in HRV values.
