Purpose: The purpose of this study was to identify the characteristics and the related factors of attachment- oriented caretaking behavior in mothers who are breast-feeding their infants. Method: The subjects were 155 mothers who participated in a healthy breast-feeding contestin the Busan area. The data were collected from September 24, 2003, and were analyzed using SPSS WIN 10.0. Results: The mothers were highly affirmative in their attachment-oriented caretaking behaviors (total mean 2.59±.502 of a possible score of 3). Among the attachment-oriented caretaking behaviors (10 items), the scores for 6 items were higher than the average score and 4 items were lower than the average score. There were significant differences in the attachment-oriented caretaking behaviors according to level of education (p＜0.05), and planned duration of breast-feeding (p＜0.001). Mothers with university education who planned to breast-feed as long as the baby wanted had higher scores. Conclusions: The above results suggest that nursing interventions which are individualized and practical are needed to encourage the attachment-oriented caretaking behaviors essential to breast-feeding mothers.

The purpose of this study is to provide basic data needed for planning apartment community spaces in order to vitalize rental apartments. Indoors community spaces of six rental apartments in Seoul and Gyung-gi were examined. The results are as follows. First, layout types of community spaces in rental apartment complexes were researched and it was found that there are singular types and block types. Depending on the layout type, the space could function as an element to closely associate residents with each other. Second, child care spaces were planned to conveniently utilize the space with space plans, and furniture and appliance plans adjusted for children's characteristics. On the contrary, elderly spaces lacked exercise equipment and subsidiary facilities, and educational spaces caused inconvenience as they did not take into consideration the user characteristics. Third, although indoor community spaces of rental apartment complexes were planned to hold child care spaces, elderly spaces, educational spaces, and neighborhood spaces according to the legal standards of installation, the operation of these facilities were problematic.

Obstacle defines all fixed and mobile objects, or parts thereof, that are located on an area intended for the surface movement of aircraft or extend above a defined surface intended to protect aircraft in flight or stand outside those defined surfaces and that have been assessed as being a hazard to air navigation. Aircraft operations are based on electronic supporting systems using radio frequencies to assist pilots. These frequencies can receive outside interference that change their courses or power, such as distortion, attenuation or reinforcements by an obstacle. This is a preliminary case study that shows the relation of instrument flight procedures and the degree of interferences introduced by a planned obstacle, which is a main bridge post, within the service volume of the radio navigation aids. For the purpose of this study, the case airport's data and it's VOR/DME and ILS systems' limitations are analyzed, as well as the relation of interferences between the obstacle and navigation aides were reviewed with the internal regulations in Korea.

Landsat images were globally used to monitoring the Earth's. But it is not positively applied to a field of environment such as coastal environment, heat island effect and drought condition and so on. Until recently, Information about a ecology natural environment came to do by direct investigation. But Information about a ecology·natural environment of wide area were quickly getting possible with the progress of remote sensing technique. Specially, the up-to-date characteristic information about an ecology·natural environment as the basic intelligence for a country development activity are very important. So, it applies the satellite images that the periodic observation of data is possible. In this study, We planned the function which is possible helping the renewal of an ecology·natural environmental information using Landsat imagery. Also planned the DB suitable for these purpose. For application of thermal infrared band images we developed the function that extracts an isothermal line. It used the thermal infrared band images and it grasped a temperature distribution. The result is useful in analysis of the city heat island effectiveness.

Purpose: The purpose of this study was to construct and test a structural equation modeling on the reproductive health behavior of single women with sexual experiences. This study employed Ajzen's Theory of Planned Behavior (TPB). Methods: The data were collected after receipt of consent from 250 single women with sexual experiences, and analyzed using SPSS 18.0 and AMOS 18.0. Results: Model fit indices for the hypothetical model were suitable for the recommended level: $x^2=362.407$, RMR=0.065, RMSEA=0.070, GFI=0.867. TLI=0.927, CFI=0.938, IFI=0.939, and $x^2/dF=2.237$. Intention showed direct effect with the biggest effect being on reproductive health behavior. Attitude, subjective norm and perceived behavioral control were found to have a direct effect on intention. Among them, perceived behavioral control revealed the largest influence. Conclusion: This study suggests that the TPB is a suitable model in explaining the reproductive health behavior of single women with sexual experience. Strategic plans for educational and intervention programs should be aimed to encourage single women to engage in reproductive health behavior.

Ultra-high voltage transformer industry has characteristic of small quantity batch production system by other order processing unlike general mass production systems. In this industry, observance of time deadline is very important in market competitive power security and company continued existence. The transformer winding is a process that rolls a coil is coated with an electric insulation material in order to generate the required voltage using the voltage fluctuation. The winding process is very important production process in the extra-high voltage transformer manufacturing industry because winding process is core process that occupy weight about half of whole process and is process that decide current ratio of transformer. This paper proposes a statistical calculation and control method of planned leadtime on the basis of real data and informations for the A company in transformer winding process. Moreover, we develop unit process scheduling system.

The term, travel-time reliability, refers to variations in journey time that travelers cannot predict. The purpose of this paper is to suggest a standard way to measure travel time reliability. A modified buffer time indicator is proposed. The index is represented by the difference between planned and actual travel times based on lognormal type travel time distribution. Using this framework, a constant function for railways and a negative parabola function for roads are discussed. The model developed is applied to the real data of Korean road and rail usages to empirically verify the methodology proposed. In this process, the unit value of travel time reliability for each group is estimated. The result of this research is expected to be helpful of conducting more cautious economic feasibility studies of transport.

Geumgang canal is planned to connect Geumgang lake with Saemangeum lake to accelerate desalinization and dilute polluted water to improve water quality in Saemangeum lake. The purpose of this study is to evaluate the impact of water quality on Geumgang lake by diversion of its lake flow to Saemangeum lake. WASP5 model was used to estimate water quality of Geumgang lake. Model calibration and verification were done for water quality data for 2001 and 2002. Water quality concentrations in Geumgang lake were simulated for 4 scenarios, which were considered whether the Geumgang canal is built or not. As a result of simulations, there was little impact on water quality in Geumgang lake, though a little of the Geumgang lake flow diverted to Saemangeum lake. As the Geumgang canal is planned to divert the Geumgang water flow which were discharged into the sea through sluice gates when canal is not built, it is thought that there will be little change by diversion of water flow.

Purpose: The purpose of this study was to identify factors related to level of satisfaction among mothers of preschoolers. Methods: Participants were 359 mothers of firstborn healthy preschoolers. The questionnaires were collected from August 1 to November 21, 2012. Data were analyzed using SPSS 20.0. Results: The mean score for degree of mothers' parenting satisfaction was 5.94 out of 7. There were significant differences in the level of parenting satisfaction according to mother's job (t=2.48, p=.014), planned pregnancy (t=3.07, p=.002), number of children (t=2.22, p=.027), and parenting education (F=4.33, p=.005). The environmental variables of age of spouse (F=3.06, p=.048) and monthly income of the household (F=2.87, p=.036) also seemed to have an influence. Analysis of predictors such as the mother's job, planned pregnancy, parenting education, overall health problems, parenting stress, perception of emotional status and behaviors in children, age of spouse, and spouse's support explained 31.5% of the variance in mother's parenting satisfaction. Conclusion: The results suggest a need to develop nursing intervention programs for parenting stress reduction, and health programs for fathers to support mothers' child rearing.
