Due to the fact that nurses may deal with diverse populations in the work place, it is very important for then to maintain appropriate interpersonal relationships with clients. Nurses should maintain diverse types of relationships appropriately with patients with special needs and their families during crisis, other nursing colleagues and staff on the same team, clients in the school or work place as well as the community. In particular, a hospital is a society with a system and hierarchy, and the importance of interpersonal relationships is much more emphasized. In interpersonal relationships, it is very important for a person to communicate with others in an accurate manner, and when the communication is not achieved appropriately, the person may have troubles and experience distress and conflicts because of the inaccurate communication of thoughts. According to the findings of previous studies, nurses actually experience much distress in the work place because of the miscommunication that they have with others. The purpose of this study was to observe a correlation between Myers-Briggs Type Indicator and assertiveness behavior, and to exam the effects of assertiveness training on the assertiveness behavior and conflict management mode. The subjects of this study included 20 persons in the experimental group and 20 persons the in control group. Myers-Briggs Type Indicator was applied before the study. The assertiveness training group received six, 120 minutes sessions over a 3 week period. Pre-test on assertiveness behavior, Communication Conflict Inventory-General, Role Conflict Inventory- General, Conflict Management Mode was achieved for all the subjects prior to the training. Post-test was administered to all the subjects one week following the last session. The data were analyzed using SPSS PC program to obtain findings on mean. standard distribution, t-test, and Pearson correlation. The results are as follows: (1) Myers-Briggs Type Indicator Introvert/Extrovert was correlated to assertive behavior and avoid- response type conflict management mode. (2) The assertiveness training was correlated to assertiveness behavior, communication conflict degree, and avoid- response type conflict management mode. (3) The post-test scores between the training group and the control group were significantly different in assertiveness behavior and avoid-response type conflict management mode. It is suggested that more studies need to be done to differentiate the effects of Myers-Briggs Type Indicator and assertiveness training on assertiveness behavior and avoid-response type conflict management mode.

In this paper, an analytic model of a sleep mode operation in the IEEE 802.16e is investigated. A mobile subscriber station(MSS) goes to sleep mode after negotiations with the base station(BS) and wakes up periodically for a short interval to check whether there is downlink traffic to it. If the arrival of traffic is notified, an MSS returns to wake mode. Otherwise, it again enters increased sleep interval which is double as the previous one. In order to consider the situation more practically, we propose the sleep mode starting threshold, during which MSS should await packets before it enters the sleep mode. By modifying the M/G/l with multiple vacations model, energy consumption ratio(ECR) and average packet response time are calculated. Our analytic model provides potential guidance in determining the optimal parameters values such as sleep mode starting threshold, minimal sleep and maximal sleep window.

The importance of Information technology (IT) has been growing. Thus, it is critical for firms to choose the optimal information technology development mode in order to ensure that maximum benefit is derived from IT. Despite its importance, however, there is little comprehensive research on choosing the IT development mode that firms undertake. To fill this gap, this study attempts to propose a parsimonious as well as comprehensive IT development framework based on strategic value and the uniqueness of IT resources. In addition, this study analyzes the impact of the fit between the theoretically proposed IT development mode and the actually used mode on the performance of Korean firms. This study contributes to and expands the literature on IT development modes by considering various development modes in real time. Moreover, the results serve as a stepping stone for managers who want to develop or adopt IT effectively.

Bimodal Tram developed by KRRI is driven by a series Hybrid propulsion system which has both the CNG engine, generator and LPB(Lithium Polymer Battery) pack. It has three driving modes; Hybrid mode, Engine mode and Battery mode. Even in case of Battery mode, LPB pack to get enough power to drive the vehicle only by itself onsists of 168 LPB cells(80Ah per lcell), 650V. It is important thing to manage LPB pack in a right way, which will extend the lifetime of LPB cells and operate in the hybrid mode effectively. This paper has shown the development of battery management system(12 BMS, 1 BMS per 14cells) to manage LPB pack which is connected with CAN(Controller Area Network) each other and measure the voltage, current, temperature and also control the cooling fan inside of LPB pack. Using the measured data, BMS can show the SOC(State of Charge), SOH(State of Health) and other status of LPB pack including of the cell balancing.

대부분의 위성들이 휠을이용한 자세제어를 수행하면서 축적된 휠모멘텀을 안정 영역으로 변동하기 위해 덤핑모드를 고려하고 있으며, 정지궤도위성의 경우에는 궤도위치유지를 위해 주기적으로 궤도조정 추력기를 동작시키면서 발생되는 자세오차를 휠 또는 자세제어 추력기를 이용하는 위치유지모드를 고려한다. 본 연구에서는 이와 같은 정지궤도위성의 임무특성을 이용하여 휠모멘텀 관리 로직을 개발하고 무궁화위성 3호 자세제어계에 적용하여 그 성능을 검증하였다.

This research report cuts across management sciences (market strategy entry mode development) and innovative technology (Electric Vehicle (EV)) alongside measures to submerge global warming. The development of a successful entry mode for the electric Vehicle into the African continent is the main objective of the study. The study focuses on an analysis of how electric car manufacturers can enter the African market in other to achieve global sustainability and social responsibility. The methodology is based on identifying the factors that affect the choice of an entry mode into international markets by multinational companies desiring to leverage their revenue through a foreign market. It also offered a quantitative approach that can support the economic and sustainability entry mode model for EVs and a qualitative approach of Porter's five forces analysis as an entry mode coaching tool for EVs. These proxies are used in quite a wide range of multivariate statistical methods (trend analysis, ratio, and probability, comparative t-test technique, auto-regression, and ordinary least square technique). The result acknowledges joint venture and setting of the plant (physical presents) as the optimal entry mode in African EV market. It requires the EV manufacturers a tire-free emission innovation technology in order to optimize the global sustainability initiative.

A firm seeking to enter a foreign market must make an important strategic decision of which market entry mode to use. Because entry modes involve resource commitments, the initial choice by a firm on a particular entry mode is difficult to change without a considerable loss of time and money. Substantial prior research has been undertaken to explain why firms select a particular entry mode into global markets. However, there exists limited research on this area in the field of foreign apparel brands in Korea, although some research has analyzed influential entry mode factors when Korean textile and clothing companies went overseas. This study reviews prior research on the entry mode choice and analyzes the factors that influence the entry mode choice for 510 foreign clothing brands in Korea. Price range, clothing types, distribution strategy, and cultural distance were considered as influential determinants for different entry mode choices. Crosstabs with a chi-square test and logistic regression are used for analysis. This study shows that high-priced brands and luxury brands are associated with the export orientated entry mode in the Korean market. Brands that pursued the strategy of multiple distribution channels showed a preference for a licensing mode or direct investment over other entry modes, and brands from higher-cultural-distance countries entered the Korean clothing market by licensing mode. The findings of this study are appropriate for the strategic planning of foreign apparel intent on entering the Korean market or for Korean apparel firms planning to enter the global market.
