This study was performed to identify the predictability of maternal authority from the perspective of children's social competence and mothers' control behavior. The subjects of this study were 369 children from an elementary school in Mokpo. The results were as follows: 1) There were relationships among children's social competence and maternal control behavior and authority. 2) Children's social competence was explained by the maternal control behavior. Maternal imperative control nagatively effected the sociability among children's social competence. Maternal position control positively effected all the children's social competence. 3) Children's social competence was explained by the maternal authority. All maternal control types changed when maternal authority was included. The change of children's social competence was related due to maternal control plus maternal authority. This result illustrates that maternal authority exhibited a powerful effect on children's social competence.

The purpose of this study is to investigate the family values and the factors of satisfying family life. Throughout the study the changes of family values and marital satisfaction were examined. The results of the study are as follows; 1) Whereas the family values of people living in urban community were modernized to a great extent- in position of wife, role of husband and wife, preference between son and daughter, view on filial piety- the family values of people living in rural community were remained its traditional form. Form both areas modernization of family values was found in support of old parent. 2) Both Seoul and Andong showed the significant difference on family values according to subjects' education and age. In Seoul, the socio-economic level was influential factor in determining subjects' family values. 3) Marital satisfaction was found higher among people living in rural community than in people living in urban community. Since its very important not only to the individual but also to the society for a human being to be content in his surrounding , the reestablishment of the housewives family values should be followed so that other family members may approach the modernized family values.

In this paper, we proposed and designed a novel SNA protocol which operates in the way of a server and a client in the power control system. The proposed SNA protocol includes the information about the mode switching, the saving position of context information, the user trigger, and so forth, which are needed in the power management devices. We consider the application of the SNA protocol to the home network, where message flows between the SNA server and the SNA client. To verify the operation of the SNA protocol, the state transition diagrams of the server in the home gateway and the client in the network device are shown. Hence, we can conclude the SNA can operate without malfuction.

The rapid proliferation of in-home and office information applications and services is driving the need for new wireless technologies enabling wideband short range multimedia communications. Due to the growing demand for higher quality media and faster wireless connections, several IEEE standardization groups are considering very high data rate alternatives physical layer(s) for Wireless Personal Area Network (WPAN). The Ultra Wide Band (UWB) multiple access technology based on very narrow pulse transmission, is one viable candidate for these applications providing very high bit rates services, low power consumption and accurate positioning capability. In this paper we provide a methodology to evaluate the UWB system BER performance in UWB wireless fading networks with power controlled UWB devices are considered. Results can be used to analyze the performance of a given network topology and to provide useful design ideas for an UWB home sensor network.

Purpose: This study aimed to present Blue Ocean strategies by deriving the strategic elements of a visiting nursing center and conducting a survey on the importance and satisfaction of care clients. Methods: First, a FGI was conducted targeting the head of the visiting nursing center to derive its strategic elements. Subsequently, importance and satisfaction surveys on the derived strategy elements were analyzed, an IPA matrix was derived, and an as-is ERRC Blue Ocean strategy was established. Kano's Three-Factor Theory was used to derive a competitive position matrix and establish a to-be ERRC Blue Ocean strategy. The Blue Ocean Strategy for Visiting Nursing Center Management is presented in this study. Results: Four as raise factors were derived from combining the results of the as-is, to-be ERRC strategy element analysis: retention of competent nurses, education in medication management, maintenance of high customer satisfaction, and prompt handling of customer complaints. Additionally, the customer's health condition evaluation was derived. Conclusion: Blue Ocean Strategies can be used to analyze, derive, and establish management strategies in various nursing-related entrepreneurship fields.

I hope to demonstrate in this paper the degree to which the works of Leonard and Virginia Woolf, mainly The Wise Virgins, The Village in the Jungle, and The Voyage Out, are contained within the politics of home. In doing so, I aim to challenge some mainstream criticism that affirms their resistance to British imperial desire. Although their statuses as outsiders in the British Empire, being a Jew and being a woman respectively, allowed Leonard and Virginia Woolf to criticize British imperialism and a male-dominated culture as well as racial and cultural hierarchies to a degree, their works inevitably unveil their prioritization of the British white-oriented space. In some ways their authorial positions in relation to their texts uphold the imperial center as an invisible regime of truth in their narratives, supporting the patriarchal and imperial binary oppositional structure and its hierarchical order imposed not only on the British subject but also on the foreign, colonial others. Leonard's and Virginia's inconsistencies and ambiguities betray their racial distantiation and notions of British white superiority, as disclosed in their racially stereotyped descriptions and the absence of real communication between the British characters and the colonial, foreign others. The work of self-repetition, the major mechanism in the politics of home, dies hard in Leonard's and Virginia's 'antiimperial' works. Leonard's and Virginia's struggle to stand against the imperial desire needs a genuine ethical position in order to embrace the Other, which would allow us to explore further and guard against the pitfall of postcolonial criticism's being easily degenerated into a neo-colonial criticism, another politics of home.

Complex sensorless control scheme is difficult to utilize in field of home appliance system because of cost problem. Therefore, it is necessary to introduce simplified sensorless control scheme that is composed of least calculation to estimate the rotor position. This paper presents the principle of the rotor position estimation with comparison of the estimated flux linkage and reference flux linkage. In order to verify the feasibility of control scheme, MATLAB is used for simulation.

With increase of servo motor In industrial and home application, a number of papers related to PMSM control have been researched. Among them, sensorless control schemes are especially concerned in the view point of its cost reduction. In the conventional approach, a rotor position is generally estimated by the integration of estimated rotor speed. In this method, because of their tight relationship between the amplitude of back-emf and rotor position. it is somewhat difficult to find two parameters at the same time. To solve this problem, a novel sensorless control scheme is proposed. It utilizes a back-emf normalization, so it does not requires the variables related with the amplitude of back-emf. The validity of the proposed control scheme was verified through experimental results.

The complex sensorless control scheme is not practical for use in the field of home appliance systems because it is not economical. Therefore, it is necessary to introduce a simplified sensorless control scheme that is composed of least calculation to estimate the rotor position. This paper presents the principle of the rotor position estimation with comparison of the estimated flux linkage and reference flux linkage. In order to verify the feasibility of the control scheme, ACSL is used for the simulation and TI DSP TMS320F240 is used for the experiment.

Recently, the skeleton type 2-phase brushless DC motor has been used in electric home appliance for low price and low energy consumption. In this paper, we analyzed a skeleton type 2-phase BLDC motor using time-step finite element method. And the validity of analysis is confirmed by measuring the flux distribution on the surface of permanent magnet and back-EMF. As well, we have calculated the dynamic characteristics of target motor considering the Hall sensor position. So, we have found the optimum switching position, and improved efficiency of 2-phase BLDC motor.
