As a part of school safety network construction project, a system of school marshal in Seoul-si and a project of academy safety guard in other regions are on the way of improvement. But, the crimes in and around the school, occurring frequently, are not solved easily, as this study points out. The effective improvement way of school safety network construction project is as followings. First, to enforce assistant-class school safety teacher system in order to nurture and educate experts in school safety, as a systematic support for strengthening occupational professionalism. Second, to enforce school safety network construction projects for construct circumstances through legal fix of school safety CPTED to make students free from crimes. This study looks into the real status and problem of school safety networks, and suggests system of school safety teacher and a legal enactment of CPTED, as systematic and a planed school safety countermeasure, not temporary.

In a globalization and information society in the 21st century, the emphasis of education is on producing people who can create intellectual value. To meet the purpose in mathematics education, students should be taught to be able to understand basic logics and principles and exchange mathematical information each other. Also they had better be guided to study on their own at home in an effective way. In reality, however, most of the home study does not go beyond confirming the same homework. It is very difficult for students to plan systematic preparation and review of their lessons and study on their own. Moreover there seems to be no integration between the lessons students receive at school and in private classes. Therefore the need for more systematic home study in relation to school lessons is high to maximize the teaming effect. Studying through Web has little restriction in terms of time and space. Students can collect useful information inexpensively and share their learning assignment with each other. But mathematics education through Web has not yet been developed in such a way as to see a positive result from it. This research intends to develop a web site where students can study mathematics systematically in a self-guided way. The research methods applied included survey, student discussion and online home study. The questionnaires were designed to figure out students'and parents'changes in their concept of mathematics home study. The research also tried to look for ways to cut down the burden of expensive private lessons in mathematics. The student discussions were made up of problem-making and problem-solving. The discussion procedure was analysed so as to check if students used their creativity while they were working. As stated above, the research aims to develop a web site to support effective home study, enhance students' mathematical ability and reduce the burden of private lessons.

The potential risks, involved with the management of a library, may cause a tremendous economic loss, so require a systematic management. The rist management process, consisting of risk identification, risk measurement selection of risk treatment methods, implementation, and monitoring and evaluation, suggests the use of insurance to deal with property risks, liability risks and personnel risks. For the systematic risk management of a library, risk manager should be appointed to be responsible for program development and insurance purchase. The limited coverage of library risks, provided by the school cooperative society, should be supplemented through development of insurance products. Further study is required to improve the library risk management and the application of insurance in a systematic and realistic way.

Purpose: Test & Evaluation items are main contents which verify performance of the development system and they are deduced going through project management system stages. However, there is no systematic or standardized framework for Test & Evaluation items, so a lot of differences occur between projects and people are questioning whether verification items are selected for the optimization of the development system. In this regard, this research proposes the process of deducing Test & Evaluation items in a systematic way during a development stage by applying QFD (Quality Function Deployment) technique which reflects customers' requirements. Methods: Test & Evaluation items are recognized as customers' requirements, and QFD technique which refines and gathers various requirements of customers effectively during general products' development stage is applied to complete HOQ (House of Quality) Conclusion: There is no specific methodology for Test & Evaluation items, so currently, they are selected by including items which are given by similar projects or higher authorities. However, by utilizing QFD technique, selection of evaluation items which goes through more systematic process is expected to be possible.

Objectives: The purpose of this systematic review is to overview and evaluate the effect on postpartum hypogalactia after acupuncture treatment. Methods: Relevant randomized controlled trials (RCTs) were identified by database searches in Embase, Pubmed, CENTRAL, CNKI, KISS. Searching keywords were "Hypogalactia" or "Hypolactaion" and "Acupuncture". After searching qualified articles, we independently assessed the risk of bias according to the Cochrane Rob criteria. Results: Among the 81 articles five RCTs were finally selected. Four of the selected were statistically significant. One of them was not statistically significant because it was comparative study of chinese medicine and acupuncture treatment. The quality of the evidence for specific comparisons ranged from low to high. Conclusions: Our systematic review found encouraging. Acupuncture treatment would be effective way to increase insufficient milk supply on postpartum hypogalactia.

Public institutions have a responsibility to ensure the safety of their employees and the public. One way to do this is to implement a systematic safety inspection system based on risk assessments and continuous improvements. This study developed a systematic safety inspection system for public institutions that are ordered construction projects. The proposed system in this study consists of a three-step process: (1) developing safety grade evaluation tables, (2) preparing and conducting safety inspections, and (3) evaluating and improving safety management grades. The first step is to develop safety grade evaluation tables by analysis and diagnosis of the construction site's work type, disaster statistics, and related laws. The second step is to conduct safety inspections using the developed evaluation tables. The third step is to determine the safety management grade based on the results of the safety inspection, and to improve risk factors found during the safety evaluation. The proposed system was implemented in highway construction projects carried out by public institutions. The results showed that the proposed system has two major effects: (1) reducing accident-related deaths and injuries, (2) improving safety management levels by continuous evaluation and improvement. The proposed system can be utilized in construction projects ordered by public institutions to improve the level of occupational safety and health.

Fashion is the second most polluting industry. We must strive to transition to a form of industry that does not cause environmental pollution. These efforts drive may fashion brands to produce and sell products with redesigned methods that delight the inventory flow. Accordingly, it is necessary to develop creative apparel up-cycling design using the creative thinking method. This study aims to produce clothing redesign works by introducing design idea types for systematic redesign creation. In this research, we conducted a literature review on the concept of up-cycling design and employed heterotopa spacial concept reflected fashion design creation methodology types. The RE;CODE, a leading domestic up-cycling design brand, was used in case analysis. According to the command of shape transformation, it is spreading, stacking, dropping, inverting and crossing, from the creative thinking method reflecting heterotopia spacial concepts, showing designers a concrete way to transform form into new apparel. Seven works of apparel up-cycling design were developed by conducting process of RE;CODE. Also, to establish an apparel up-cycling design creation process for creating works. In this study, we proposed a systematic method for apparel up-cycling design, including a method for reorganizing two or more different materials to create something new and ultimately reversing the structure. The value and significance of this study is that it proposes a systematic method for apparel up-cycling design to make it new.

The fact on a variety of the plane coordinate systems in cadastral survey field caused a troublesome stage by different standards for the production of cadastral maps. The cadastral maps with different origins are not standardized in terms of unit and coordinate system, which introduces surveying problems at the edges where two or more zones meet. Moreover, difficulties in the creation of seamless digital cadastral map DBs between different coordinate systems has become the obstacle to establish various levels of spatial information systems for the efficient management of Korean Peninsula. Therefore, the aim of the study is to present a way to mutual coordinate transformation by clarifying the systematic differences between the areas of different origins.

The advent of KM(knowledge management) concept have led many organizations to seek an effective way to make use of their knowledge. But the absence of right tools for systematic handling of unstructured information makes it difficult to automatically retrieve and share relevant information that exactly meet user's needs. we propose a systematic method to enable content-based information retrieval from corpus of unstructured documents. In our method, a document is represented by using several key terms which are automatically selected based on their quantitative relevancy to the document. Basically, the relevancy is calculated by using a traditional TFIDF measure that are widely accepted in the related research, but to improve effectiveness of the measure, we exploited 'concept network' that represents term-term relationships. In particular, in constructing the concept network, we have also considered relative position of terms occurring in a document. A prototype system for experiment has been implemented. The experiment result shows that our approach can have higher performance over the conventional TFIDF method.
