We adapted association rules of data mining in order to investigate the relation among the factors of musculoskeletal disorders and proposed the method of preventing the musculoskeletal disorders associated with multiple logistic regression in previous study. This multiple logistic regression was difficult to establish the method of preventing musculoskeletal disorders in case factors can't be managed by worker himself, i.e., age, gender, marital status. In order to solve this problem, we devised association rules of factors of musculoskeletal disorders and proposed the interactive method of preventing the musculoskeletal disorders, by applying association rules with the result of multiple logistic regression in previous study. The result of correlation analysis showed that prevention method of one part also prevents musculoskeletal disorders of other parts of body.

Coating ceramic balls activate water molecular in water as radiate far-infrared radiation of high efficiency, and then prevent formation of scale and corrosion of pipe. Therefore, but only keep away drop of heat exchange efficiency of boiler, not also remove formed scale. As a result, pipe of boiler has clean and has form thin protection film in inner of pipe. Also, the water treated by rust preventing system using the ceramic balls, that is harmless, tasteless, odorless, and non-toxicity in the human body, and it can use drinking water. This rust preventing system can save energy and protect environment.

For the pleasant dwelling place, the most of apartments are designed with the increased green area ratio in ground space and the underground parking lot. However, the condensation in underground space has occasionally occurred due to the insufficient ventilation and insulation treatment. Despite reinforcement of the insulation treatment and mechanical ventilation for the preventing method of condensation. It seems difficult to expect preventing effects for the condensation without consideration of the thermal characteristic of structures. Furthermore, no fundamental measure has been established because maintenance work for these defects incurs a lot of costs and these defects could be occurred again. This study suggests a new method for preventing floor surface condensation through analyzing the reasons of condensation which occurred in the underground floor.

In this study, in the coating-sheet composite waterproofing method, a specimen was formed to prevent the transmission of the no-node tensile stress occurring under the junction between sheets by forming an insulating structure when the junction was formed, and to compare the effect of preventing breakage with the existing common junction. For this, tensile performance evaluation was conducted. As a result of the evaluation, it was confirmed that it exhibited higher tensile strength compared to the existing joint and at the same time exhibited a large width of displacement characteristics, and thus, had an effect of preventing breakage.

Purpose: This study was to identify behaviors preventing the recurrence of breast cancer and the level of quality of life. Methods: This descriptive study was conducted using a structured questionnaire from November 1, 2006 to December 25, 2006. One hundred and twenty two women breast cancer survivors were recruited by convenience sampling. Results: The most frequent behavior for preventing recurrence of the breast cancer was dietary treatment (90.9%) and exercise (86.8%) was the second behavior. In addition, most of them perceived these behaviors as 'very effective' (82.8%). The degree of the quality of life of a breast cancer survivor was 5.34 point indicating a 'medium level'. Conclusion: Breast cancer survivors pursued various behaviors for preventing recurrence of breast cancer. Therefore, the nursing interventions should be focused on a systematic educational approach considering healthy behaviors to prevent breast cancer recurrence for breast cancer survivors.

Purpose: This study describes the development of a violence prevention educational program for elementary school children using empathy (VPEP-E) that teachers can use during class. Methods: Hoffman's theory of empathy and Seels and Richey's (1994) ADDIE model were applied to develop this program. Results: The developed program consisted of eight sessions: "Orientation/definition of violence and empathy", "Types and boundaries of violence", "Look into my feelings", "Say it with a facial expression", "Preventing non-empathic violence due to social prejudice", "Preventing physical violence", "Verbal and online violence prevention: empathic conversation", and "I can do well: review of the whole curriculum". The program was evaluated by 15 elementary school teachers, who considered it to be easily accessible to elementary school students. The final VPEP-E, which will be provided in eight times for 40 minutes each for fifth-grade students, will provide a basis for preventing violence by fostering empathy. Conclusion: We expect the developed educational program to be effective in preventing violence among elementary school students. However, further research involving children from various age groups is needed.

The purpose of this study is to examine the necessity of 'emergency plumbing equipment for preventing the spread of water leakage'. It reviews social and economic costs when there is spread of water leakage and finds out that those are enormous. Expansion of water leakage causes conflicts between neighbors, economic loss and inconvenience from damages on facilities like elevator and power failure. Next, it examines the inability of existing plumbing equipment when it comes to spread of water leakage. Newly defined 'Surface Leakage' means rapid leak in the surface, and 'Internal Leakage' means seeping out slowly and gradually buried in the pipeline. It will also be analyzed by separating the concept of a leak in the two concepts of a 'Surface Leakage' and 'Internal Leakage'. It proposes emergency plumbing equipment for preventing the spread of water leakage as a solution for the expansion of water leakage. It explains general concepts of emergency plumbing equipment for preventing the spread of water leakage. It will also examine the effectiveness of the user by performing a survey of 420 multi-level building their opinion on the effects of an emergency plumbing equipments to prevent the spread of water leakage.

Despite a lot of efforts, school violence is getting severe nowadays and especially it seems remarkably occurring among middle school students. Many studies show that most school violence occur in classrooms where the students spend most of their time in studying and socializing for their everyday life. The purpose of this study is to identify design elements of middle school classroom and to suggest some design plans for preventing school violence, in the point of view of CPTED. For this objective, six middle schools were selected from Gangseo-gu, Seoul, and the questionnaire and survey were conducted to identify the status of school violence and the physical classroom environment in each schools. An analysis was carried using SPSS to identify the correlation between the school violence and the physical environmental design elements. The results are as follows : although each selected school shows different status of school violence and the physical environment in classrooms, commonly the occurrence and the fear of violence are related to the classroom environment. Therefore, In order to plan classroom for preventing school violence, 'the proper size of classroom avoiding overcrowd', 'elevation design for the sense of belonging and territoriality', 'improvement of deteriorated environment' should be considered for reduce the causes of violence. And 'maximization of natural surveillance from hallway', 'accessibility of teacher' should be considered for rapid management of violence.

In recent years, globalization of markets and increased consumer sophistication in automotive industry have led to an increase in the variety of products and a consequent increase in the number of variants of any given product line that a manufacturer must supply. Also, the modularity trend of automotive production systems greatly affects on the production systems of automotive parts suppliers. These typically requires the implementation of cost efficient, flexible production systems, so called mixed-model assembly lines. We studied the problems of mixed-model assembly and assembly error-preventing techniques, and developed the error-preventing monitoring system using RFID in the mixed-model automotive parts assembly line. Especially, this study aimed to solve the problems and supplement the existing systems for preventing assembly errors, by developing a monitoring system using RFID to minimize the issues currently occurring in the field of automotive parts assembly, such as losses from incorrect installation and omission.
