Purpose: The purpose of this study was to analyze periodic screening behaviors for breast cancer and factors affecting the screening behaviors among hospital nurses. Methods: A total of 461 nurses were recruited from 15 hospitals located in two southern areas of Korea. The Champion's Health Beliefs Model Scale-Korean version and a structured study questionnaire were used for data collection. Data were collected during July and August 2008. Results: Nurses who performed periodic mammography accounted for 15.6% of the total, while 22.8% performed periodic breast self-examination (BSE). Among married nurses, the rates of periodic mammography and BSE were significantly different by age, menopausal status, delivery experience, family history of breast cancer, and experiences of cervical cancer screening. Significant factors affecting periodic mammography were family history of breast cancer, experiences of cervical cancer screening, age above 40, and performance of periodic BSE. For health beliefs, levels of severity, confidentiality and barrier were significant factors for periodic BSE. Conclusion: Nurses, who are role models for health promoting behaviors, did not adequately performing periodic BSE and mammography. A health promotion program for breast cancer designed for hospital nurses is needed to improve performance rates for periodic screening behaviors for breast cancer.

This study was carried out to investigate what factors affect satisfaction of periodic health examination undertaken by employees. The purpose of the study was to improve quality of periodic health examination and to increase the rate of workers participation in the screening test. The content of questionnaire was designed with focus on the satisfaction and attitude on the periodic health examination. Data were analyzed with 212 males, 181 females among 393 samples who took periodic examination at a general hospital in Seoul. Korea. The results were as follows: 1. Respondents were mainly in the thirties(42.7%), married(58.5%), more than 3 years working experiences(66.7%) and employed in Sales & Customers service industry(60.1%). 2. There were significant differences in the scores of satisfaction by general characteristics among the respondents. The highly educated and the single showed higher satisfaction on the periodic health examination than other respondents. 3. The scores of satisfaction in periodic health examination showed highly influenced by level of age, work duration, level of knowledge to the health screening and income. Based on the results, this study concluded that the periodic health examination might be necessary to modify its items according to the clients characteristics and their individual demands for maintenance of healthy life.

This study is concerned with cost analysis in periodic maintenance policy. Generally periodic maintenance policy in which item is repaired periodic interval times. And in the article minimal repair is considered. Minimal repair means that if a unit fails, unit is instantaneously restored to same hazard rate curve as before failure. In the paper periodic maintenance policy with minimal repair is as follows; Operating unit is periodically replaced in periodic maintenance time, if a failure occurs between minimal repair and periodic maintenance time, unit is replaced by a spate until the periodic time comes. Also unit undergoes minimal repair at failures in minimal-repair-for-failure interval. Then total expected cost per unit time is calculated according to maintenance period and scale parameter of failure distribution. Total cost factors ate included operating, fixed, minimal repair, periodic maintenance and replacement cost Numerical example is shown in which failure time of system has erlang distribution.

This paper is concerned with cost analysis model in periodic maintenance policy. Generally periodic maintenance policy in which item is repaired periodic interval times. And in the article minimal repair is considered. Mimimal repair means that if a unit fails, unit is instantaneously restored to same hazard rate curve as before failure. In the paper periodic maintenance policy with minimal repair is as follows; Operating unit is periodically replaced in periodic maintenance time, if a failure occurs between minimal repair and periodic maintenance time, unit is replaced by a new item until tile periodic maintenance time comes. Also unit undergoes minimal repair at failures in minimal-repair-for-failure interval. Then total expected cost per unit time is calculated according to scale parameter of failure distribution. Maintenance cost factors are included operating, fixed, minimal repair, periodic maintenance and new item replacement cost. Numerical example is shown in which failure time of system has weibull distribution.

In this paper, we proposes a study on the derivation of inspection factors for the periodic inspection of large buses equipped with AEBS and LDWS. we investigate the safety evaluation (NCAP) of domestic and foreign vehicles and safety standards for the two functions currently in operation and analyze the evaluation factors, measurement methods and evaluation scenarios and so on. In addition, the test scenario was derived by analyzing the vehicle safety evaluation data already held, Therefore, we use an real large bus and the inspection elements for the periodic inspection were derived.

This study analyzes stress intensity factors for a number of periodic edge cracks in a semiinfinite medium subjected to a far field uniform applied load along with a distribution of eigenstrain. The eigenstrain is considered to be distributed arbitrarily over a region of finite depth extending from the free surface. The cracks are represented by a continuous distribution of edge dislocations. Using the complex potential functions of the edge dislocations, a simple as well as effective method is developed to calculate the stress intensity factor for the edge cracks. The method is employed to obtain the numerical results of the stress intensity factor for different distributions of eigenstrain. Moreover, the effect of crack spacing and the intensity of the normalized eigenstress on the stress intensity factor are investigated in details. The results of the present study reveal that the stress intensity factor of the periodic edge cracks is significantly influenced by the magnitude as well as distribution of the eigenstrain within the finite depth. The eigenstrains that induce compressive stresses at and near the free surface of the semi-infinite medium reduce the stress intensity factor that, in turn, contributes to the toughening of the material.

In this paper, the software reliability growth model which incorporates the periodic maintenance after the release is proposed. Using the proposed model, the debugging and periodic maintenance cost subject to the required level of the software reliability are investigated. An optimal software release time is derived for a fixed interval of periodic maintenance. To validate the proposed model, release times obtained in this study are compared with examples. The proposed investigation is expected to be served as one of factors in determining the release time of the software where periodic maintenance is considered.

The purpose of this study was to explore the periodic changes of apartment supply between 1980 and 2001 in the City of Donghae. A survey was conducted with 82 apartment complexes that were built in during 21years. The data were itemized and specified by the unit house area, story, periodic and local apartment distribution. They were classified by five:(5) periods and analyzed by each apartment complexes for building characteristics. There were found that apartment housing were influenced by many primary factors such as demographics and a lot of the housing politics etc. The results of this study were as follows: 1) Apartment supply in the City of Donghae mass-produced from 1980 to 2001; Especially the forth period was supplied 5,999 households. 2) Between south area and north area was found a regional disparity. 3) The exclusive use $34{\sim}66m^{2}$ were continuously and centrally supplied according to the housing policy and practical demand. 4) For the types of story were variously found ; Especially the below 5 story apartment was continuously supplied.
