  • This study was intended to provide women who are experiencing menopause with effective nursing care by exploring the menopause experience. The purpose of the research was to understand the subjective feelings of women about the question of what the menopause experience is. Q-Methodological method was used for that purpose. As the research method, Q-statements were collected preliminary to the study of through in -depth interviews and a literature review. For the study 34 Q-statements were selected. There were 21 women as subjects for the research. The 21 women sorted the 34 statements using the principle of Forced Normal Distribution. The principle of Forced Normal Distribution, which has nine scales to measure the individual opinions, was called Q-Factor Analysis by using PC Quanl Program to supply the material. As a result, there were four categories(self-com-passion type, self-regulation type, self-perception type, self-abandonment type) of special opinion about the menopause experience in these women. The first type was called Self-compassion This type' was associated with varying degrees of emotonal instability(psychological withdrawal). And type in menopause signifies loss of a socially valued status and may result in depressive symptoms. This type expresses the menopause experience as associated with negative reaction. The second type is called Self-regulation. This type overcomes the menopause experience more actively than the other types and do not express the menopause experience as one of suffering. This type make efforts by themselves to regulate the mono-pause experience. The third type is called Self-perception. This type perceives the experience of menopause which as typical menopausal syndrome (hot flashes and decreased vaginal lubrication, decreased estrogen producing atrophic changes of the labia and vaginal mucosa, making intercourse uncomfortable). The fourth type is called Self- abandonment. This type denies the experience of menopause. The meaning of menopausal experience is significantly related with a life accident or life load. Also, This type experiences pain in the musculoskeletal system. As a result, The meaning of the menopausal experience is affected by perceived subjective experience of the nurses, the need to understand each persons meaning of the menopause experience and to develop appropriate nursing interventions based on the typology of menopause experience. Finally. The result of the study will provide basic data for nursing intervention the menopausal women.

  • In recent years, some converter structures and analyzing methods for the voltage regulation of stand-alone self-excited induction generators (SEIGs) have been introduced. However, all of them are concerned with the three-phase voltage control of three-phase SEIGs or the single-phase voltage control of single-phase SEIGs for the operation of these machines under balanced load conditions. In this paper, each phase voltage is controlled separately through separated converters, which consist of a full-bridge diode rectifier and one-IGBT. For this purpose, the principle of the electronic load controllers supported by fuzzy logic is employed in the two-different proposed converter structures. While changing single phase consumer loads that are independent from each other, the output voltages of the generator are controlled independently by three-number of separated electronic load controllers (SELCs) in two different mode operations. The aim is to obtain a rated power from the SEIG via the switching of the dump loads to be the complement of consumer load variations. The transient and steady state behaviors of the whole system are investigated by simulation studies from the point of getting the design parameters, and experiments are carried out for validation of the results. The results illustrate that the proposed SELC system is capable of coping with independent consumer load variations to keep output voltage at a desired value for each phase. It is also available for unbalanced consumer load conditions. In addition, it is concluded that the proposed converter without a filter capacitor has less harmonics on the currents.

  • Safety management was divided by the competent authorities supplier, and customer with responsibility and authority. Gas accident were caused by treatment problem on the supplier and user, on technical and use management mater, on facilities and goods, and included problem with gas safety connection system. Especially, the big accident of the inside and outside of the country occurred during recent year was newly recognized with the whole society about safety. This study is present standard application plan of each department to use planning gas technical standard and gas utilization standard of introduction model than statute for change of self-regulation management system and complicated regulation of examination center and order.

  • Modem Robot is used in all industries. Previous Robot was used by simplicity work, at recent times, robot is developed in form that can do action such as a person. Robot's action runs according to command repeat or in the every moment according to sensor's output value, achieve other action. In this raper, we studied about self-regulation transfer robot that follow Object autonomously. This robot can be used by purpose that carry heavy burden instead of human. Robot's composition is drive part which run object's position awareness Sensor, Processor that control action and Motor part. After robot is connects with Network, we did robot remote control and monitor the action situation of robot. For the methode to reduce drive error, we developed algorithm for outside environment. For an experiment we made the self-regulation robot. We showed the directivity of sensor, error of directivity and soft moving of robot. We showed the monitoring system and the execution screen for communication between robot and PC.

  • The purpose of this study was to explore the unfairness of adhesion contracts for internet contents service. The internet contents were classified into six types of avatar, learning, download, e-book and movie internet sites. The adhesion contracts of internet contents service were collected in 60 internet sites. The unfairness of the adhesion contract was reviewed under the adhesion contract regulation act. The major results were as follows. First, the obligation of clear statement, explanation, and delivery was not observed completely. Second, many articles of adhesion contract were unfair and they especially violated articles 7 and 9. Therefore, the standard adhesion contract system for internet content service should be enforced and self-regulation of information service providers is needed.

  • The previous work(Cheong et al., 2006) where the characteristics of acoustic emissions of wind turbines has been investigated according to the methods of power regulation, has showed that the acoustic power of wind turbine using the stall control for power regulation is more correlated with the wind speed than that using the pitch control. In this paper, basically extending this work, the noise generation characteristics of large modern upwind wind turbines are experimentally indentified according to the power regulation methods. To investigate the noise generation mechanisms, the distribution of noise sources in the rotor plane is measured by using the beam-forming measurement system(B&K 7768, 7752, WA0890) consisting of 48 microphones. The array results for the 660 kW wind turbine show that all noise is produced during the downward movement of the blades. This result show good agreement with the theoretical result using the empirical formula with the parameters: the convective amplification; trailing edge noise directivity; flow-speed dependence. This agreement implies that the trailing edge noise is dominant over the whole frequency range of the noise from the 660 kW wind turbine using the pitch control for power regulation.
