민간경비업 종사자의 내부마케팅요인이 감정노동과 직무만족에 미치는 영향
정귀영,김두한,하정훈 한국민간경비학회 2014 한국민간경비학회보 Vol.13 No.4
The purpose of this study is to investigate the effects of internal marketing factors for private security guards on emotional labor and job satisfaction. We distributed 280 questionnaires and used 259 of them for the final analysis. We used PASW WIN Ver. 18.0 statistics solution for data analyses, including frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis and multiple regression analysis. The result is as follows:First, the internal marketing factors recognized by private security guards have partial effects on their recognition of emotional labor, depending on sub-factors. Second, the internal marketing factors recognized by private security guards have partial effects on job satisfaction, depending on sub-factors. Third, the emotional labor factors recognized by private security guards have partial effects on their job satisfaction, depending on sub-factors. On the basis of these results from the statistical research,We can suggest the conclusion as follows: First, managerial staff above the intermediate level in the private security companies should continuously provide specialized technical training in order to positively activate the operating environment of emotional labor in which the lower level employees work, and also activate the service interface with the customers. The specialties acquired in the technical training can raise flexibility in operation when responding to customers, which will result in positive customer recognition to the employee and will vitalize the business of the company in effect. Second, in order to raise job satisfaction among the employees of a private security company, the management should utilize multiple ways to provide rewards appropriate for the job performance, so that the employees are conditioned to be motivated to acquire specialties and knowledge. What is needed is Management support systems that extend the opportunity for the employees to receive compensation for their professional skills through regular pay raises and evaluation on employee during various activities in and out of the working hours. The professional skills would be utilized in the job processing. Third, the best business strategy to solve the problem in the customer service interface situation would be to efficiently manage the working hours of each employee and promote a working condition that can relieve the individual’s problem-inducing stress. More specifically, it would be better to operate a separate communication channel that dedicates to responding to customer complaints, or to execute a communication training for the welfare of the employees.

원형 용융탄산염 단위 연료전지에서 수성가스 전이반응의 영향
정귀영,김미현 弘益大學校 科學技術硏究所 2000 科學技術硏究論文集 Vol.11 No.-
본 연구에서는 단면이 원형인 용융탄산염 단위 연료전지에 대한 수치모사를 수행하여 수성가스 전이반응을 포함하지 않았을 때의 오차를 살펴보았다. 원통형 연료전지에서 물질수지 및 에너지수지식을 세우고 코드화하여 여러 작동 조건에서 온도분포, 전류밀도 및 가스의 전환율 등 전지의 성능을 살펴보았다. 또한, 수성가스 전이반응이 포함되지 않았을 경우와 비교하였다. 전류밀도가 일정할 때 원형 단위 연료전지의 각 부분에서의 온도분포는 대체로 고른 분포를 보였다. 전지 입구에서 수소의 농도가 높아 전기화학반응이 많이 일어나 많은 열이 발생하기 때문에 음극 가스의 온도가 상승하다가 전지의 내부에서 거의 일정하게 온도가 유지되고, 또한 전지의 바깥에 가까워질수록 전환율의 증가율이 크게 된다. 전지로 유입되는 음극 가스 중에는 일산화탄소가 없기 때문에 평형에 도달하기 위해 수성가스 전이반응이 역반응으로 빠른 속도로 진행되어 전지의 입구부분에서 기울기가 더 크게 나타난다. 전류 밀도가 같을 때 수소가스 전이반응이 포함되었을 때의 전지전압이 포함되지 않았을 때보다 더 적게 나타난다. 전지의 입구에서 수성가스 전이반응이 역반응으로 진행되어 수소가 더 소모되고 일산화탄소의 분율은 증가하게 되어 음극의 분극저항 값이 상재거으로 커지기 때문이다. Effects of the water-gas shift reaction on the pedal' lances of the circular molten carbonate unit fuel cell were studied by a mathematical modelling. After setting up the mass and the energy balance equations, performances of the unit cell, such as the temperature distributions, the current density and the conversion distribution, were obtained and compared with the case without considering the water-gas shift reaction. When the current density was constant, temperature distributions were uniform. The temperature of the anode gas increased and maintained constant, because the concentration of hydrogen was so high that the electrochemical reaction was active and a lot of heat was generated. As a result, the change of the conversion of gas was high. There is no carbon monoxide in the entering anode gas so that the water-gas shift reaction progressed reversely to reach an equilibrium state and the slope of the conversion of anode gas is high. At a same current density, the cell voltage was lower when the water-gas shift reaction was included. Since the water-gas shift reaction progressed reversely, in the direction of consuming hydrogen and generating carbon monoxide, so that the anodic polarization was relatively big.

대구 일부 지역 중학생의 식행동·체질량지수와 영양소 섭취상태에 관한 연구
정귀영,이영순,김성미 동아시아식생활학회 2005 동아시아식생활학회지 Vol.15 No.1
Dietary behavior, body mass index(BMI) and nutrient intake status of 185 boys and 205 girls in 3rd grade middle school students in Daegu area were analyzed. Boys were 168.6㎝ tall and weighed 61.3㎏ on the average and girls 158.5㎝ and 54.4㎏, respectively. From their BMIs, 17.9% were classified as the underweight, 54.2% as the average, 14.7% as the overweight and 13.2% as the obesity. The average energy intake per day was 2222.6 ㎉ for boys, 1796.2 ㎉ for girls which were 83.3% and 86.6% of the RDA, respectively. Composition rate of carbohydrate, protein, fat in relation to energy intake was 62.4 : 16.5 : 21.1 for boys and 58.8 : 16.0 : 25.2 for girls. Protein was taken low and carbohydrate and fat were high in this study. Particularly, fat intake rate of girls was high. Calcium, iron, vitamin A, and vitamin B2 did not meet the RDA and especially calcium was taken 63.9% for boys and 54.01% for girls. Most of the students have tendency to eat irregularly and to overeat. For the nutrients intake, calories and calcium intake were lower than the RDA regardless of gender and iron intake was not enough for girls only. In relation to BMI, obesity group students were taking lower calories and proteins than the normal students were. No consistent trend was shown for boys about nutrient intake in relation to eating speed. Students had a correct perception of their body image which was similar to that of their mothers. Nutrient average intake is under the average and the percentile under 70% of RDA was high contrary to the fact that nutrient intake like calcium and iron was exceedingly important particularly in the growth process. Therefore, nutritional education for the proper intake of nutrients was required for the students in Daegu area. Especially, education has to be focused on the balanced diet and correct food choices for the proper dietary behaviors.
