  • In this study, the pros and cons of TPM and RCM were comparatively evaluated at various aspects : a, pp.ication process, objectives, maintenance items, organizations, analysis of maintenace methods, etc. It is found that TPM can be considered as a management discipline. However, in TPM, there seldom exist concrete rules or guidelines to select a maintenance scheme. RCM, which is a widely used maintenance scheme for aircrafts or power plants, has a good analysis and decision logic for maintenance planning. In the paper, similar decision rules are adopted to TPM deployment to get an effective and effecient maintenance Planning.

  • The pros and cons of deposition metals, alloys and compounds from organic, inorganic and molten salt non-aqueous plating baths are discussed. Although some metals, alloys and compounds not obtainable otherwise can be deposited, few commercial processes exist. Widespread use is limited by the cost, complexity, and hazards associated with non-aqueous electrolytes, coupled with the relatively small markets for many of these coatings.

  • Objectives: Recent studies have shown that tailoring to women's individual beliefs and stage of cancer screening adoption increase the probability that cancer screening will ensue. To identify variables associated with cancer screening behavior, many studies for cancer screening have used the Transtheoretical Model(TTM). This study was carried out to identity the cognitive and behavioral factors associated with breast cancer screening by stages of change among women, forties aged. Methods: Building on the TTM constructs, we collected the data to test the association with cognitive and behavioral factors for breast cancer screening by stage of change among women, forties aged (N=232), using the self-reported questionnaire. The stages of change were grouped according to screening participation and intention for breast cancer as precontemplation, contemplation, preparation, action, and maintenance. We found out the association between breast cancer screening and cognitive and behavioral factors, and testified the difference between stages of change by chi-square test, one-way ANOVA, and multiple comparison analysis(Duncan test). Results: Analyses of 232 women showed that participation on mammography was 68.1% within lifetime and 46.1% within last 2 years, and we found out the association with breast cancer screening participation, intention and cognitive-behavioral factors. The stages of change based on participation and intention were different from the decisional balance, the screening attitude, and the self-efficacy(p<0.01). The decisional balance was differ from stages of change because the difference on opinions about pros(positives) and cons(negative) were likely to significant by stages of change(p<0.05, p<0.01). Conclusion: To increase the screening rate for breast cancer, it should be developed the tailored message and recommend guideline. And the tailored message should be designed to increase the pros of breast cancer screening(mammography) and to decrease the cons, and considered the woman's stage of adoption.

  • Objective: This study aims to survey and compare three systemic accident investigation techniques of Accimap, STAMP and FRAM, based on the application studies of the Sewol ferry accident. Background: Traditional accident investigation methods such as domino models, FTA, etc. work well for losses caused by physical component failures or actions of human in relatively simple systems, but are unable to depict mechanisms generating errors and violations in the current complex socio-technical systems. For better understanding the structure and behavior of the socio-technical systems, systemic techniques have been developed and used. Method: This study was mainly based on survey of literatures through surfing webpages of ScienceDirect and Google, and ergonomics relevant journals. The key words of Sewol, Sewol ferry, Sewol ferry accident, etc. were used in the survey. Results: Three systemic accident investigation methods included similar actors in the Sewol ferry accident including government, Ministry of Ocean and Fisheries, Korean Coast Guard, Korean Register of Shipping, Korea Shipping Association, Chonghaejin Marine Company, crew members. The methods graphically represented each level's failures or performance variabilities of relevant functions and relationships between them. It was shown that the systemic methods consider the entire system, ranging from the environment in which the accident occurred, to the role of government in shaping the system of work. Each method has its own comparative pros and cons, but the Accimap has advantages in terms of time of analysis, data required, model complexity and degree of comprehensiveness. Conclusion: This study reviewed and compared three systemic accident investigation methods, which showed that there are systemic characteristics and pros and cons in the methods. Application: The results would be used as a guideline when selecting accident investigation methods.

  • Objectives: This study was conducted to evaluate the effects of a tailored program based on the Transtheoretical Model to smoking cessation in high school girls. Methods: A quasi-experimental research design was used in this study. The participants were 35 industrial high school girls who have been smoking. The girls were allocated to an experimental group(18) and a control group(17) by randomization. For intervention, the experimental group received the group smoking cessation program and individual program which tailored according to the stage of change. A common group smoking cessation program was given to the control group. Data were collected before the program, immediately after and 4 weeks after the program was completed and were analyzed with repeated measure ANOVA. Result: In the experimental group, the daily smoking amount, nicotine dependency and decisional balance(Pros) score were significantly decreased and the self-efficacy score were significantly increased at one month after the intervention in comparison with before and immediately after it. The decisional balance(Cons) and processes of change score of the experimental group were significantly increased at immediately after the intervention and one month after it in comparison with before it, and at one month after it in comparison with immediately after it. A significant difference in the daily smoking amount, urine cotinine, nicotine dependency, decisional balance(Pros, Cons) and processes of change score between the both groups was found after one month of intervention. Conclusions: The tailored smoking cessation program was more effective, compared to the common smoking cessation program on smoking behavior, self-efficacy, decisional balance, processes of change. This program can be used for favorable changes in high school girl's smoking behavior.

  • Purpose: To evaluate a reducing alcohol intervention program for workers. Method: The intervention program employed one-group pretest-post-test design with repeated measuring by quasi-experimental study. The program was developed from literature review based on the Transtheoretical Model, and evaluated from April 6 to June 22, 2006. Sixteen white collar male workers participated. At the beginning, the subjects were at the pre-contemplation stage (50%) and contemplation stage (50%). The intervention was applied personally or in group twice a week for 9 weeks. Results: The scores of each stage of change in the post-test increased significantly compared with those in the pretest. The scores of process (cognitive and behavioral) of change in the post-test increased significantly compared with those in the pretest. The score of self-efficacy of change in the post-test increased significantly compared with that in the pretest. The score of pros-cons for drinking in the post-test decreased significantly compared with that in the pretest. The consumption of alcohol a week and a day in the post-test decreased significantly compared with that in the pretest. The levels in ALT, AST, GGT, total cholesterol, triglyceride, B.P. and BMI in the post-test did not decrease significantly compared with those in the pretest, but the level of FBS decreased significantly compared with that in the pretest. Conclusion: The above result informs us that a stage-based reducing alcohol intervention program for workers has the effect of increasing the stages of change, the process of change (cognitive and behavioral) and self-efficacy, and decreasing pros-cons for drinking alcohol consumption and FBS, and it also has a value as an effective means of nursing for workers.

  • Due to increasing impervious surfaces resulting from urbanization and industrialization which are directly linked to urban inundation and non-point pollutants runoff, there is a need to manage them systematically. A management over urban impervious surfaces calls for pervious/impervious maps, which enable viewing the distribution of impervious surfaces. Nevertheless, relevant data are absent as now. In this respect, despite the diversity of proposed methods, pilot implementation and accuracy verification have never been conducted. Therefore, this study is aimed to produce a pilot pervious/impervious map based on previously proposed methods and to elucidate its pros and cons with a view to proposing a method for producing a GIS-based optimal pervious/impervious map. Following previously proposed methods, a pervious/impervious map of Bupyeong-gu, Incheon was produced. Then, a method of producing optimal pervious/impervious maps applicable to urban areas was proposed through the comparison of pros and cons of relevant spatial data. As a result, the map had been confirmed 99.2% of classification accuracy. Based on the present findings, future studies should establish a standardized method for producing. Also, this method should be used to produce pervious/impervious maps of other regions so that it can be applied to managing impervious surfaces in major urban areas nationwide.
