This paper presents a study on the modeling for transparent toaster with a cap of folding type. The toaster was modelled to solve problems of customer's unsatisfaction such as heat loss, input of a piece of dirt, unidentified heating state of sliced toaster. Rapid prototyping was followed by the first modeling, and the second modeling was implemented in order to solve the problems of the first modeling such as interference of holder and door, and the third modeling was developed with a cap of folding type through analysis of assembly and simulation. The 3D modeling tool used in this paper was Pro/Engineer 4.0. The modeling was designed to minimize heat loss and structured with transparent outer case. So the toasting procedure will be identified with the naked eye, and the transparent toaster will improve the customer's aesthetic satisfaction.

The purpose of this study is to examine the eco-systemic factors that affect the married immigrant women's employment. The subjects were 229 married immigrant women who live in Ulsan city. Collected date were analyzed through frequency, percentage, and logistic regression analysis. The results are as follows. The factors that affect the married immigrant women's employment are the education level of husband, acquisition of citizenship, Korean language ability, job training experience, and the support of their parent-in-law. According to these findings, intervention strategies that focus on increasing the married immigrant women's employment are suggested.

The paper is aimed to develop coaching competency model for executives and analyze their needs. For better outcome, we take coaching experts and executives and managers with business coaching experience as the target and conduct Delphi survey three times. According to the 3 surveys, we derived 5 coaching competency clusters and 34 individual competency items. The next thing, we have designed 102 survey questions which measure the 43 competency items and verified the validity for 272 respondents composed of managers and executives participated. As a result, the Analysis is secured with the validity at the 26 competency items. To investigate the competency that is important to executives, we carry needs analysis into execution. Borich's needs to utilize executive coaching competencies results conducted on 5 priority groups that belong to the competence of the 26 sub-competencies have business acumen the needs of high-capacity was analyzed. followed by motivation inspiring, organizational management, conflict management, strategic thinking and negotiation skills.

This study analyzes the effect of leadership styles (transformational leadership, transactional leadership, and servant leadership) of CEOs at small and medium-sized enterprises on the organizational effectiveness of the employees (organizational commitment and organizational citizenship behavior). A survey was conducted on 573 employees of domestic small and medium-sized enterprises in the electric, electronic, and IT industries, and the data was used to perform statistical analysis. As the result, charisma of transformational leadership, individual consideration, emotional healing of servant leadership, wisdom, and stewardship were shown to have positive effect on the organizational commitment. Furthermore, charisma of transformational leadership, exceptional management of transactional leadership, wisdom of servant leadership, and stewardship were shown to have positive effect on organizational citizenship behavior.

In this study, recycling methods of nano $TiO_2$-coated silica-bead were conducted in order to solve a deactivation problem of bead that had been invented for decomposition of pollutants in aqueous solution. Surface cleansing was selected as the recycling method for used beads. The surface cleansing was done with four different solutions such as distilled water, surfactant, acetone, and ethyl alcohol(ethanol). The recycling process consists of cleansing and calcination. After cleaning the used (deactivated) beads, calcination was done at $100^{\circ}C$, $200^{\circ}C$ and $300^{\circ}C$ for 30 minutes, respectively. This process was repeated three times. The activity of the recycled bead was measured by photo-degradation of methylene blue. The result shows that acetone cleansing and calcination at $100^{\circ}C$ for 30 minutes was the most efficient recycling method.

Three books of home economics were published in Korea 1907 and approved as textbooks for women's education by Korean government from 1908 to 1910 and by the Choseon Government-General from 1912 to 1914. The textbooks contained modern knowledge about housing which was focused on hygine matters and most systematic among the knowledge of that time. The original book of the three was Sinsen Gajunhak(新選家政學) by Shimoda Yutako published in Japan 1990 after her surveying western home economics knowledge. It means the modern housing knowledge educated in Korea around 1910 was affected by Western modern thinking in home economics field that gave the responsibility of housing cleanness for family members' health to housewives. So the knowledge even made the educated women to practice their learning only as wives, which was still traditional.

도시철도 운영기관에서 사용되는 감시카메라 및 센서의 수는 운영기관마다 수천 개 이상에 이르고 있으며, 그 수는 지속적으로 증가하고 있다. 역사 시설뿐만 아니라 현재는 차량 내에도 카메라 및 센서를 설치하고 있거나 설치할 예정이다. 또한 도시철도의 안전에 대한 요구가 증대되면 될수록 이러한 안전설비는 증가할 수밖에 없다. 그러나 현재까지 이렇게 많은 곳에 설치된 카메라 및 센서들과 안전 설비를 효율적으로 관리할 수 있는 방안은 없다. 아직까지 폐쇄회로 텔레비전에 의존한 수동적인 감시체계에서 벗어나지 못하고 있으며, 각종 센서 등도 독립적으로 기능을 수행하고 있어 기능의 중복투자 및 비상시 종합적인 판단을 하기에는 한계를 가지고 있다. 또한 새로운 안전시스템과 기존 시스템과의 호환성 및 확장성 등에 문제를 발생시킬 수 있으며, 종합 관제실 등에서도 종합적인 판단을 실시하고 상황발생시 즉각적인 대응을 하는 데는 많은 문제점을 가지고 있다. 이를 위해 본 논문에서는 도시철도 운영기관별 정보통신시스템 현황 및 종합감시시스템 발주사양서를 비교 분석하여, 도시철도 종합감시시스템에 대한 표준규격을 도출하였다.

High-speed Portable Internet system provides 1-3 Mbps data transmission speed to terminals moving up to 60 km/sec. Since High-speed Portable Internet system supports services requiring different QoS, it needs an efficient scheduling method based on those different QoSs. This paper shows the performance comparisons of several different packet scheduling schemes for minimizing the mean delay over the downlink of High-speed Portable Internet system to support the packet data service. Simulation results show that proposed scheme superior to other schemes at side throughput and data loss rate.

This paper analysed the ionized fields around HVDC transmission line by the use of the charge simulation method. As this is very complex and expressed by a non-linear partial differential equations, it is hard to solve problems analytically. So, we developed a computer program which can apply in multi-polar HVDC transmission line with conductor bundles and calculated conductor surface gradient, corona current density and ion charge density to prove validity of a proposed algorithm in this paper.

In this paper, the efficient prevention of cross talk technique for basically avoiding the confusion problem between the overlapped ubiquitous network of the other object is developed within the same area. The intelligent unified wireless network remote meter reading system of the ubiquitous ZigBee base is developed based on this technology. Therefore, in this paper, each meter reading equipments managed the information of its own adjacent ZigBee channel. The intelligent network system steadily transmitting data a relay was developed based upon this information in each region through the flexible channel conversion technique.
