Purpose: The purpose of this study is to investigate how empowering leadership effects on growth needs and turnover intentions to emergency medical technicians. Methods: The study was based on seventy six paramedics and seventy EMTs-basic who were working at the fire stations. A survey questionnaire was used to prove connection between empowering leadership, growth needs, and turnover intentions. Results: There was a positive correlation between empowering leadership and growth needs, and negative correlation between empowering leadership and turnover intentions. There was a positive correlation between emergency medical technicians growth needs and turnover intentions. Conclusion: This analysis is empirically applied to study the empowering leadership focused on the empowerment act of leader to a leading role to empowerment in fire service organization.

Objective : To investigate the efficacy of endoscopic third ventriculostomy (ETV) for infantile hydrocephalus. Methods : Retrospectively reviewed the 17 infantile hydrocephalus cases who were treated with ETV between July 2009 and June 2013. The study includes 17 patients (4 Han and 13 Hui) between the ages of 51 and 337 days. Five cases with encephalitis history and 2 cases with cerebral hemorrhage, with the remaining 10 cases congenital hydrocephalus. ETVs were performed for all patients with 1 case failing because the severe ventricle inflammatory adhesion, excessive exudation, and vague basilar artery. Results : Among the 16 successful cases 7 cases improved remarkably : heads and ventricles reduced and cerebral cortexes thickening morphologically. The ventricles of the remaining cases were unchanged. Conclusion : The ethnic minority account for the majority of the patients in this study. ETV is effective for infantile obstructive hydrocephalus.

The paper presents a generalized optimal active control algorithm for earthquake-resistant structures. The study included the weighting matrix configuration, stability, and time-delays for achieving control effectiveness and optimum solution. The sensitivity of various time-delays in the optimal solution is investigated for which the stability regions are determined. A simplified method for reducing the influence of time-delay on dynamic response is proposed. Numerical examples illustrate that the proposed optimal control algorithm is advantageous over others currently in vogue. Its feedback control law is independent of the time increment, and its weighting matrix can be flexibly selected and adjusted at any time during the operation of the control system. The examples also show that the weighting matrix based on pole placement approach is superior to other weighting matrix configurations for its self-adjustable control effectiveness. Using the time-delay correction method can significantly reduce the influence of time-delays on both structural response and required control force.

This study aims to examine the relative importance of various tasks of EMT and to examine knowledge level and problems associated with AED. It is based on the survey of paramedics and 119 rescures. The results for this study were as follows ; Among the tasks of EMT, 'foreignbody removal from mouth' were rated as the most important, followed by '$O_2$ supply', 'CPR', 'Intubation for CPR', '$O_2$ supply' were rates as the most necessary, followed by 'foreignbody removal from mouth', 'external bleeding control'. In terms of the knowledge level about AED, survey respondents are most knowledgeable about 'role of other rescures during the preparation for AED' and 'treatment after 3 AEDS. The most important reason that the uses of AED is delayed is 'unclear boundary of treatment directed by medical control'. The results of the study suggest that we need guideline for EMT's tasks, efficient communication system between 119 and emergency health are center for prompt AED, and training and education program for AED.

Ferry Golden Jindo collided with Ferry Princess near the No.7 light buoy of Incheon Port No.1 Passage in restricted visibility due to dense fog. The result was that Ferry Golden Jindo got a hole at the starboard midship section shell plating and Ferry Princess sustained damages at the starboard bow and 25 persons injured The aim of this paper is to investigate this collision accident, to clarify its causes, and to prevent such accident from occurring again In short, this collision resulted from Princess' high speed in restricted visibility, Golden Jindo's carelessness of watchkeeping, lack of proper safety training of crew, lack of instruction of supervisor, carelessness af PTMS Center and indifference of Korea Shipping Association, etc.

In this paper, a method for identifying the appropriate position on the ground plane for antennas is proposed based on the current correlation coefficient ($C^3$). This method explains that the mutual coupling between antennas when locating several antennas on the same ground plane is necessary. Given the current distribution on the ground plane induced by each antenna, easily estimating the coupling between antennas is possible. This paper also demonstrates that the proposed method can be used in the design of a multi-input multi-output system. The measured data are in good agreement with the simulation results.

An integrated magnetic (IM) transformer is proposed for a phase shifted full bridge (PSFB) converter with zero voltage switching (ZVS). In a proposed IM transformer, the transformer is located on the center leg of E-core and the output inductor is wound on two outer legs with air gap. The proposed IM transformer is analyzed by using the magnetic capacitor model. For reducing the core size, EE core is redesigned. The proposed IM transformer is experimentally verified on a 1.2 kW prototype converter. The converter efficiency with the proposed IM transformer is about 93 % at full load and its volume size can be reduced. It can be expected that the power density can be largely increased with the proposed IM transformer.

Objective: The purpose of this study was to identify the effect of dynamic postural balance control against tilting platform between golfers and non-golfers. Method: 24 golfers and 26 non-golfers were participated. Eight motion capture cameras, two force plates, and one dynamic balance control platform were used for sensory perception test. It was performed two-way repeated ANOVA with a Bonferroni adjustment at a significant level of a 0.05. Results: Golfers' perception ability was higher than non-golfer according to slope. the CoP, time, angle variables were indicated main effect and interaction effect between golfer and non-golfer. Conclusion: It was known that golfer's proprioception perception ability was higher than non-golfers. Repeated practice such as shots and putting on the uneven ground might improve their balance control.

Purpose: his study examines the effect of message valence on consumer perceptions of sales messages and salesperson evaluations in retail contexts. In contrast to previous studies on the negativity effect, it examines the positivity effect, which implies that the effect of positive information may outweigh that of negative information in certain situations. In addition, the current research examines how the content of the sales message influences consumers' perceptions of salespeople. Research design and methodology: The study presents an analytical model in which a potentially altruistic salesperson transmits quality information as a form of cheap talk. Several predictions were derived from the model and then empirically tested in two experiments. Results: When the sales message is about relatively less expensive products, positive information can be more credible and diagnostic than negative information. In addition, positive sales messages about the less expensive products signal the salesperson's benevolence. Conclusion: This paper is one of the few studies to predict and empirically test the positivity effect. It also contributes to the literature on trust in salespeople by showing that message valence influences buyers' perceptions of salespeople.
