In order to investigate the comfort properties of aerobic wear with different materials, the physiological responses, subjective wear sensation and microclimate were measured. The experimental garment were all-in·one type with half·length sleeves made of cotton/ polyurethane and nylon/ polyhrethane fabrics. The conditions of the experimental room were controlled to maintain two type of environ- ments, i.e. $25{\pm}1^{\circ}C$, $60{\pm}5\%$ R. H. and $30{\pm}1^{\circ}C$, $70{\pm}5\%$ R.H., Air velocity was maintained at 0.25 misec all the time. The results are as follows; 1) At $25^{\circ}C$, mean skin temperature and comfort sensation were not significantly different among 2 types of materials. 2) At $30^{\circ}C$, aerobic wear made of cotton/polyurethane fibers showed better pleasant tactile sensation than that of nylon/polyurethane fibers. 3) Under both environmental conditions, microclimate of two types of aerobic wear was not significantly different. 4) Among several aspects of wear sensations, tactile sensation was the most powerful factor to differenciate material differences of aerobic wear.

For many companies, selling in an international market place is the ultimate challenge. One of the greatest problems facing exporters is the increasing insistence by importers that trade be conducted on open account terms. This often means that payment is received many weeks or even months after delivery. Unsurprisingly, many organisations find that giving buyers credit in this way can cause severe cash flow problems. Further problems can arise if the importer delays payment beyond originally agreed terms or makes no payment at all because of financial failure. In particular, many SMEs find it difficult to finance their production cycle, since after goods are delivered most buyers demand 30 to 90 days to pay. Therefore, International factoring for SME has been developing very rapidly in the world trade financing markets. Functions of international factoring as trade financing is a comprehensive financial service that includes credit protection, accounts receivable bookkeeping, collection services and financing. Factoring can be a powerful tool in providing financing to high-risk, informationally opaque sellers. International factoring is very helpful for international exporters to get competitiveness in the world markets. In Korea, a few banks are operating international factoring. But International factoring in Korea could not play a key roll as general trade supporting service. So, This study is to suggest importances of international factoring development for trade development and to investigate real operation situations and problems by way of interviews with operators in banks that are operating international factoring and suggest development strategies for international factoring in Korea.

With the advent of ubiquitous computing society, many advanced technologies have enabled wireless sensor networks which consist of small sensor nodes. However, the sensor nodes have limited computing resources such as small size memory, low battery life, short transmission range, and low computational capabilities. Thus, decreasing energy consumption is one of the most significant issues in wireless sensor networks. In addition, numerous applications for wireless sensor networks are recently spreading to various fields (health-care, surveillance, location tracking, unmanned monitoring, nuclear reactor control, crop harvesting control, u-city, building automation etc.). For many of them, supporting security functionalities is an indispensable feature. Especially in case wireless sensor networks should provide a sufficient variety of security functions, sensor nodes are required to have more powerful performance and more energy demanding features. In other words, simultaneously providing security features and saving energy faces a trade-off problem. This paper presents a novel energy-efficient security architecture in an IEEE 802.15.4-based wireless sensor network called the Hybrid Adaptive Security (HAS) framework in order to resolve the trade off issue between security and energy. Moreover, we present a performance analysis based on the experimental results and a real implementation model in order to verify the proposed approach.

Purpose: This study was to investigate the factors influencing performance of preceptors and preceptees. Method: The selectees were composed of 27 preceptors and 27 preceptees. The preceptors were given twenty six hours of education and training concerned with theory and practice and then the preceptors mentioned above gave the preceptees vis-a-vis education and training for four weeks. The data were collected through a questionnaire survey of general characteristics, performance, autonomy, empowerment, organizational commitment. The data were analyzed using t-test, ANOVA, Pearson's correlation coefficient, and the Stepwise multiple Regression. Results: The differences of performance, autonomy, organizational commitment and empowerment were found to have a significance between preceptors and preceptees in preceptorship. The performance was significantly correlated between autonomy, organizational commitment and empowerment of the preceptors and preceptees. Stepwise multiple Regression analysis for performance revealed that the most powerful predictor was empowerment. These variables accounted for 37.7%(preceptors) and 54.6%(preceptees) of variance of the performance. Conclusion: The findings above indicated that the preceptorship was significant as nursing management intervention to increase nurses' performance. Therefore it may be necessary further to develop and apply, such as performance, autonomy, empowerment, organizational commitment in preceptorship.

Purpose: This study was performed to measure the justice of compensation (distributive justice, procedural justice) and the intention of turnover perceived by nurses, and to identify the relationship between these two variables. Method: This study was a cross-sectional survey. From May 26 to June 30, 2008, data were collected from the 300 nurses working at 6 general hospitals in 5 cities, Korea. Result: The score of compensatory justice was 2.47(distributive justice was 2.46, procedural justice was 2.48), and the score of turnover intention was 3.39. The Pearson Correlation Coefficient between these two variables was -.496. The perceived compensatory justice(distributive justice, procedural justice)by nurses, their age and working periods were the affecting factors on their turnover intention, and the power of explanation of these affecting factors was 43.4%. Conclusion: According to the results, procedural justice is the most powerful factor among these affecting factors. Therefore, it is concluded that to decrease nurses' turnover intention, nursing or hospital managers have to fairly operate their compensation system, especially procedural justice, in their organization.

A powerful interaction mechanism is one of the key elements for the success of smart TVs, which demand far more complex interactions than traditional TVs. This paper proposes a novel interface based on the famous touch interaction model but utilizes long-range bare hand tracking to emulate touch actions. To satisfy the essential requirements of high accuracy and immediate response, the proposed hand tracking algorithm adopts a fast color-based tracker but with modifications to avoid the problems inherent to those algorithms. By using online modeling and motion information, the sensitivity to the environment can be greatly decreased. Furthermore, several ideas to solve the problems often encountered by users interacting with smart TVs are proposed, resulting in a very robust hand tracking algorithm that works superbly, even for users with sleeveless clothing. In addition, the proposed algorithm runs at a very high speed of 82.73 Hz. The proposed interface is confirmed to comfortably support most touch operations, such as clicks, swipes, and drags, at a distance of three meters, which makes the proposed interface a good candidate for interaction with smart TVs.

In recent years, several paradigms have been identified to simplify the design of fault-tolerant distributed applications in a conventional static system. Leader Election is among the most noticeable, particularly because it is closely related to group communication, which provides a powerful basis for implementing active replications among other uses. On the other hand, despite its usefulness, to our knowledge, no study has focused on this problem in a mobile computing environment. The aim of this paper was to propose an algorithm for the leader election protocol in a fixed station based wireless networks environment. The election algorithm is much more efficient than other election algorithms in terms of the fault tolerance.

Strong outflows from active galactic nuclei (AGNs) may play a crucial role in galaxy evolution. Integral-field spectroscopy (IFS) is the most powerful tool to study the detailed kinematics of AGN outflows. We present the on-going optical 3D spectroscopic survey of ionized gas outflows. Type 2 AGN sample is uniquely selected from SDSS DR7 with a luminosity-limit (i.e., L[O III] > $10^{41.5}erg/s$) as well as strong kinematic signatures of ionized gas outflows ([O III] velocity shift > ~200 km/s or [O III] velocity dispersion (FWHM) > 1000 km/s), defining an extremely rare population (< ~0.5%). Thus, these AGNs with strong outflow signatures are one of the best suites for investigating AGN feedback. The IFS observations cover several kpc scales for the central region of the host galaxies, providing a detailed information of the kinematics and geometry of the gas outflows. In this contribution, we report the current status of the survey and the preliminary results on gas kinematics of 18 AGNs, based on the Magellan/IMACS-IFU and the VLT/VIMOS data.

The purpose of this study is providing a usage of exterior, interior finish materials and color scheme for architectural design and the actual texture and pattern plans of finish materials from Le Corbuisier's work, Chapel Ronchamp. Chapel Ronchamp was analyzed to support the study for the interaction between texture usage and color expression. As a powerful design tool, texture, pattern and color of finish materials are very effective to alter the perception of the facade in the building. Most of architectural buildings, shapes and materials of elevations are monotonous and uniform. This study should be considered by details in the elevation of Chapel Ronchamp. As the part for developing and planning of architectural design, researching color plans and finish material is very important on real expression in the architectural space. As a result, this study will benefit in planning both the exterior and interior environments of color and finish material with texture and pattern.
