이 연구는 불법 성콘텐츠 접촉과 불법 성콘텐츠 유통의 그 원인요인들 및 통제요인들을 제시하고 그 요인들 간의 상호작용효과를 각각 살펴보고 비교하였다. 원인요인으로는 낮은 자기통제력, 불법 성콘텐츠 경험 친구, 그리고 가부장가정 요인을, 그리고 통제요인들로는 도덕태도, 공식처벌, 기회제약을 다뤘다. 그리고 세 원인요인들의 영향에 대한 세 통제요인들의 조절 혹은 완충효과를 살펴보았다. 서울시 대학생을 조사대상으로 하는 분석결과 대체로 불법 성콘텐츠 접촉과 불법 성콘텐츠 유통에서 그 원인요인들의 작용은 유사해 낮은 자기통제력, 불법 성콘텐츠 경험 친구, 그리고 가부장가정 모두가 크게 유의미했고 그 중에서도 불법 성콘텐츠 경험 친구와의 접촉의 영향력이 가장 컸다. 불법 성콘텐츠 접촉 및 유통에 대한 원인요인들과 통제요인들의 상호작용효과에 대한 결과를 보면 그 결과가 상이했다. 불법 성콘텐츠 접촉의 경우 원인요인들과 통제요인들과의 상호작용효과가 모두 유의미하지 않았다. 즉 불법 성콘텐츠 접촉에서는 원인요인 모두가 독립적으로만 유의미하게 작동했으며 그 작용을 어떠한 통제요인들도 통제하지 못했다. 그러나 불법 성콘텐츠 유통의 경우는 낮은 자기통제력과 도덕태도간의 상호작용효과, 불법 성콘텐츠 유통 친구와 도덕태도간의 상호작용효과가 유의미했고, 가부장가정과 공식처벌간의, 그리고 가부장가정과 기회제약간의 상호작용효과가 유의미했다. 그 결과의 함의를 논의한다.

In this paper, the feasibility of the cost function having two control factors were discussed in compared to two others which has one different control factor respectively. As of the control factors, the dynamic response of a discrete system and the vibrational intensity at the reference point which is the connecting point of a discrete system to a flexible beam were controlled actively by the control force obtained from the minimization of the cost function. The method of feedforward control was employed for the control strategy. The reduction levels of the dynamic response of a discrete system and the vibrational intensity at a reference point, and also the input power induced by the control force were evaluated numerically in cases of the three different cost functions. In comparison with the results obtained from the cost functions of one control factor, which is the dynamic response or the vibrational intensity, in most cases of the cost function of two control factors the better or similar results were obtained. As a conclusion, it is surely noted that both the dynamic response and the vibrational intensity of the vibrating system be controlled up to the expected level by using the single cost function having two control factors.

The purpose of this study was to examine the relationship among consumer's perceived risk of apparel purchase in internet shopping mall, control, and impulse buying. The subjects were 319 female college students in Gyeongsang provinces. The obtained data were analyzed by reliability analysis, analysis of frequency, factor analysis, cluster analysis, one-way ANOVA, Duncan's multiple range test, correlation analysis, and t-test. The major results of this study were as follows: First, three factors of consumer's perceived risk of apparel purchase in internet shopping mall were identified: size risk, trust risk, and social/psychological risk. Second, the subjects were categorized into three different types of groups according to perceived risk: high perceived risk type, middle perceived risk type, and low perceived risk type. Third, three control(self-control, goal-control, and desire for control) and three impulse buying(impulsive buying for showing off, impulsive buying for excitement, and impulsive buying due to memory) were identified. Fourth, there was significant difference between strong control group and weak control group on three factors of impulse buying. Fifth, a significant positive correlation was found size risk and three factors of control and a significant negative correlation was found self-control and three factors of impulse buying.

Purpose: This study was conducted to identify factors influencing compliance of multidrug-resistant organism infection control in intensive care units (ICU) nurses. Methods: Data were collected from 254 ICU nurses who were working at 6 general and advanced general hospitals in D city and G Province. Results: 77.2% and 84.4% of the subjects correctly answered to questions about Methicillin-Resistant Staphylococcus Aureus (MRSA) and Vancomycin-Resistant Enterococcus (VRE), respectively. The scores of MRSA infection control compliance and VRE infection control compliance were 3.41 and 3.43, respectively. The factors influencing MRSA infection control compliance were empowerment, environmental safety recognition, and education satisfaction, which explained 30% of MRSA infection control compliance. The factors significantly related to VRE infection control compliance were empowerment, hospital types, environmental safety recognition, number of education sessions, and neonatal ICU, which explained 37% of VRE infection control compliance. Conclusion: It is necessary to develop efficient educational programs for infection control including educational contents to improve empowerment and environmental safety recognition of nurses. Furthermore, administrative support for those infection control programs is also necessary.

This research analyzed the factors for crack generation and proposed the recommended construction methods for the efficient crack control of underground RC box structures under the roadway. The selected main factors were: details of contraction joints, ratio of crack control rebars in longitudinla direction, and placement of flyash concrete. These factors were tested on the actual structures and the significance of each factor was analyzed, The results show that the flyash concrete placement and the inducting minor cracks in a certain direction by adopting contraction joints are practical and efficient methods to control cracks. The significance of crack generating factors increases as the sectional loss of contraction joint spacing increase. It was recommeded that the sectional loss should be higher than 20 percent to maximize the crack generating effects. It was not possible to verify the effect of crack control rebar spacing, but it was estimated that the ratio of crack control rebar should be increased to minimize cracks.

Objective: The aim of this study is to find the optimal values of sliding factors which influence the mechanical emotion of users when they use sliding type mobile phones. Background: There are various researches that study the emotion of using mobile phones. They focus the correlation between emotion words and design factors and use the commercial products by the subjects in the experiment. However, it has a limit in finding the optimal point of emotional factors because we can search the restricted values in the mass production of the products. Therefore, we will find the optimal points by realizing the full range of the user's mechanical emotion. Method: First, we need to get the detailed factors which can describe the mechanical emotion in sliding up and down the mobile phone. Next, we find the control factors by considering the correlation between the factors of the sliding emotion and the possibility of quantitative design. To find the optimal points on the control factors, we make a sliding evaluation system which can help users feel the sliding mechanical emotion by realizing control factors. Finally, we find the optimal points by doing the experiment the system being used. Results: The critical values of the factors which are the main variables of this study are Open Max Force and Dead point Ratio. The optimal point of the Open Max Force is 200~250g/f, and the Dead point Ratio is 40~50%. Conclusion: In this study we develop the sliding evaluation system to realize the control factors of the sliding type phone and find the optimal values of the critical factors. Application: The results can be used as the criteria for designing sliding type phone.

Purpose: Emergency medical service (EMS) personnel are at high risk of spreading infection. In this study, we used the PRECEDE model to identify the knowledge, status, and barriers to infection control among Korean paramedics to provide basic infection control data. Methods: A total of 164 respondents were analyzed for the study. A questionnaire was administered and collected through an online self-response platform. Descriptive analysis, t-test, ANOVA, multiple regression, and logistic regression analyses were performed to determine infection control practices and associated factors using SAS 9.4. To identify the pathways and direct, indirect, total effects based on the PRECEDE model, we used AMOS 26.0. Results: Highly rated self-efficacy (OR 8.82, 95% CI: 3.23-24.09), awareness (OR 6.05, 95% CI: 2.06-17.72), and enabling factors (OR 3.23, 95% CI: 1.18-8.78) led to superior infection control. As a result of the structural model analysis, the highly rated enabling factors and awareness led to superior practice patterns. Conclusion: Practice is related to self-efficacy, awareness, and enabling factors; however, further research is needed to develop strategies for infection control. In particular, institutional arrangements are needed to improve the enabling factors. Improving infection control performance may lead to better infection control and enhanced protection of EMS personnel and patients against infection risks.

IPQC system was introduced for the flight safety at the age of scientific safety management in the 1980s. In spite of performing this system, aircraft accidents caused by human factors, which were above 70% among all flight accident factors, have not been reduced. Accordingly, throughout this paper I analyzed the aircraft accident factors by means of a literature study and a pilot survey. Then, based on the notion of TQC(Total Quality Control), I hierarchically classified Individual Quality into Capacity Management, Safety Management, and General Management and did the low-ranked management factors as well. AHP (Analytic Hierarchy Process), one of the scientific management methods, was used for estimating the relative importance of Individual Quality Control factors and the heavy aircraft accident causes over the last 20 years were analyzed according to the flight ranks. Based on the comparative analysis of results derived above, an IPQC model as flight ranks is established. In short, according to this newly suggested model we can obtain the maximum flight safety with the preventive actions against aircraft accidents caused by human factors and by improving the operation effect under the reasonable pilot management.
