This study is a pilot study to confirm the effectiveness of training after applying emergency simulation training for inactive nurses and to present a new model of simulation training operation method. In this study, the control group is a group that directly participates in the simulation activity, and the experimental group is the group that observes the control group's simulation activity. Experimental group and control group were matched 1:1 to experience all the roles of the resuscitation team. The study participants were 5 inactive nurses in the experimental group and 5 inactive nurses in the control group, and the total training time was 5 hours. The emergency simulation operation composition consists of theory education, skill education, and simulation. The interview was conducted. The educational satisfaction of the participants was 4.65 points for theory education and 4.70 points for practical education based on 5 points. Participants' performance confidence improved from 3.60 points before operation to 7.20 points after operation. Emergency simulation operation consisted of pre-test, theory education, skill education, simulation implementation, debriefing, and post-test. Participants expressed that the choice of group greatly reduced the burden and anxiety about performing the role of the resuscitation team. However, difficulties and inexperience in the operation of the defibrillator were reported in the experimental group. The control group reported that the simulation activity of the experimental group was not significantly different from theirs. Through the results of this study, it was confirmed that emergency simulation education not only reduced the burden and anxiety of inactive nurses, but also had an effect of education. Based on the research results, it is proposed to expand the participants and verify the effectiveness of education through specific variables such as learning commitment, learner confidence, simulation satisfaction, and team effectiveness.

In line with the expansion of electric railway, reducing carbon emission and optimal train operation are required by economical, eco-friendly and efficient management. Most of the energy consumption in electric railway is consumed by train operation. So it is important that minimize the energy consumption in train operation. An analysis of the operation performance of the new model vehicle which in South Korea, Korail introduced shows that the energy consumption is different in line with the skill level of the engine driver. In this study, the know-how of train operation of a skilled engine driver is systematized by using artificial intelligence, and the technique which supports engine drivers with train operation was offered. As a result of applying in South Korea, the Gyeongbu line by using simulation, it confirmed that the maximum 20% can reduce the energy consumption in comparison with unskilled engine drivers in case of applying the Expert System.

The comparison of prediction errors in geopotential height, temperature, and precipitation forecasts is made quantitatively to evaluate medium-range forecast skills between Global Seasonal Forecasting System version 5 (GloSea5) and Unified Model (UM) in operation by Korea Meteorological Administration during 2014. In addition, the performances in prediction of sea surface temperature anomaly in NINO3.4 region, Madden and Julian Oscillation (MJO) index, and tropical storms in western north Pacific are evaluated. The result of evaluations appears that the forecast skill of UM with lower values of root-mean square error is generally superior to GloSea5 during forecast periods (0 to 12 days). The forecast error tends to increase rapidly in GloSea5 during the first half of the forecast period, and then it shows down so that the skill difference between UM and GloSea5 becomes negligible as the forecast time increases. Precipitation forecast of GloSea5 is not as bad as expected and the skill is comparable to that of UM during 10-day forecasts. Especially, in predictions of sea surface temperature in NINO3.4 region, MJO index, and tropical storms in western Pacific, GloSea5 shows similar or better performance than UM. Throughout comparison of forecast skills for main meteorological elements and weather extremes during medium-range, the effects of initial and model errors in atmosphere-ocean coupled model are verified and it is suggested that GloSea5 is useful system for not only seasonal forecasts but also short- and medium-range forecasts.

Abstract-In paper, an operation support software for combustion control of refuse incineration plant is developed using fuzzy model and genetic algorithm. It has two major modules which are simulation module and optimal operation module. In simulation module modelling is performed to obtain fuzzy model of the refuse incineration plant and obtained fuzzy model predicts outputs of the plant when inputs are given. This module can be used to obtain control strategy, and train and enhance operators' skill by simulating the plant. And in optimal operation module, genetic algorithm searches and finds out optimal control inputs over all possible solutions in respect to desired outputs. In order to testify proposed operation support software, computer simulation was carried out.

Since recent construction projects become larger and complicated, the level of difficulty of management skill is rising, and the risk is increasing accordingly so the necessity of improving management skill of projects is increasing. In order to solve this problem, Construction Management system was preferentially introduced in construction projects but in case of domestic construction industry, separate contracts by business boundary are being made so the actual state is that the function of the Construction Management system is not properly operated over the overall projects. The partial operation of Construction Management system like this may impose many restrictions on converged and combined projects such as smart grid and intelligent buildings etc. in the future. For improvement of management skill of domestic construction projects, the competence of project management skill by work areas that can overcome heterogeneity of the current project management skill shall be secured, and any factor that impedes cooperation ability shall be found and that shall be solved. Therefore, the difference of work competency of project management system of construction and electrical construction is to be analyzed by utilizing IPA model in this study, and a plan to introduce the project management system of electrical construction for efficient operation of projects is to be looked into.

The purpose of this study was to investigate workers' perception on the quality improvement of Korean restaurants for the globalization of Korean food. A total of 342 workers at Korean restaurants in Seoul and Gyeonggi province were surveyed using a self-administrated questionnaire. Excluding responses with significant missing data, 250 responses were used for data analysis. In terms of the improvement of service quality attributes, the 'sanitation management (4.51)' category received the highest score, followed by 'service skill (3.93)', 'menu development (3.90)', 'serving method (3.88)', 'facility and ambiance (3.84)', and 'food taste (3.40)'. There were significant differences of workers' perception on the improvement of service quality which were 'menu development (p<0.01)', 'service skill (p<0.001)', 'facility and ambiance (p<0.001)', and 'sanitation management (p<0.01)' by restaurant operation type, and 'service skill (p<0.001)' and 'facility and ambiance (p<0.001)' by workers' position. The mean score of each service quality category showed that Korean restaurants managed by a franchisor were ranked the highest. In each service quality category, the items which showed the highest scores for the improvement were 'developing the finest cuisine (4.08)', 'providing food seasoning according to customer requests (3.70)', 'proving ladles, tongs, and extra plates which enable customers to take as much food as they want (4.12)', 'staff's ability to explain menu (4.08)', 'using tableware appropriate to each dish (4.03)', 'sanitary management of the provided tableware (dishes, spoons and knives) (4.57)', and 'thorough toilet management (4.57)'. This research suggests that Korean restaurants need to improve service quality to globalize Korean food, and the strategies for service quality management should be developed to be applied to each restaurant operation type.

Purpose: Even though the breast is not removed, women with a breast conservative operation(BCO) are suffering from the psychosocial distress comparable with mastectomies. The purpose of this study was to identify how clinical nurses view essential nursing problems and nursing approaches to post operative breast cancer experiences. Method: To identify the clinical nurses's interpretation, they were asked to respond to a case involving a woman struggling with breast cancer. The nurses' responses were analyzed using a manifest content analysis strategy to determine themes in problem identification and nursing care strategies. Result: The clinical nurses recognized that most of the patient's experiences originated from a psycho-social problem. Fifteen nurses(83%) interpreted the breast cancer woman's experience derived from her psychosocial problem. They identified the most effective nursing approaches for breast cancer women following surgery as counseling and providing information. Conclusion: In conclusion, the results revealed that a psychosocial skill including an empathic communication skill is essential for excellent nursing in post operative patient care.

Formal Safety Assessment (FSA) has been mostly implemented on the hardware aspects of vessels. Although there are guidelines regarding human error FSAs, there have not been many assessments in such areas. To this end, this study seeks to use precedent studies for the safe operation of DP vessels, conducting an FSA regarding human error of DP LOP (Loss of Position) incidents. For this, the study referred to precedent studies for the frequency of DP LOP incidents caused by human errors, adding the severity of LOP incidents, and then applying them to the Bayesian network. As a result, the study was able to confirm that among DP LOP incidents caused by human errors, the drive-off from skill-based errors was 74.3% and the drive-off from unsafe supervision was 50.5%. Based on such results, RCOs (Risk Control Options) were devised through a brainstorming session with experts coming up with proposals including providing mandatory DPO training, installing DP simulator on the vessels, drawing up measures to understanding the procedures for safe operation of DP vessels. Moreover, it was found that mandatory DPO training is reasonable in terms of cost benefits and that while installing a DP simulator is not suitable in terms of cost benefits, it can significantly reduce risks when operating DP vessels.
