This paper introduced the thermal characteristics of Moss Rosenberg Verft spherical tank type LNG Carrier. Especially described the temperature variation during cooling down condition. It is not easy task to calculate the temperature variation because of unsteady state condition. In this paper, computer simulation program is developed by using a Tomas Algorithm on unsteady state condition and compared with calculation results and experimental results on existing LNG Carrier voyage.

Objectives : This study analyzes the characteristics of hospital organization structures, insurance claims reviews and assessment tasks and their effects on hospitals in Pusan. Methods : The data for this study were collected through interview and self-administered surveys in 109 hospitals. The study included only - hospitals with a minimum of 50beds and excluded those providing only dental, psychiatric, or long-term care. Results : The findings of this study state that the number of beds has an influence on the organizitional structure. Conclusions : Hospital managements should seek human resources management(the insurance claims reviewer and evaluator) schemes that take into account the characteristics of the medical institution. In addition, insurance claims review and assessment tasks in hospitals require considerable knowledge and experience, and hospitals should be equipped with staff that have the relevant expertise. Therefore, to further deepen knowledge, comprehensive training should be continuously carried out in order to produce specialists in claims review and assessment.

Purpose: The purpose of this study was to identify factors influencing workplace bullying among Korean hospital nurses. Methods: Subjects in this study included 178 hospital nurses who attended two nationwide nursing educational conferences in 2013. The data was collected using self-report questionnaires which were used to identify the subjects' characteristics, self-esteem, perception of nursing organizational culture, and workplace bullying experience. Results: The results showed that 19.1% of study subjects reported being victims of workplace bullying and mostly experienced person-related and work-related bullying. Multiple regression analysis was done to identify factors affecting workplace bullying. The perception of relation-oriented culture, task-oriented culture and self-esteem turned out to be variables that explained nurses' workplace bullying, and these factors accounted for 32.0% of the variance. Conclusion: The findings suggest that nurses experience more workplace bullying in task-oriented cultures. However, they experience less bullying and report higher self-esteem and awareness in relation-oriented cultures. Interventions focused on the characteristics of the organization need to be developed to prevent workplace bullying in hospital nurses.

Up to the 60's cigarette paper commercial grades were simply described as ' non combustible ', ' combustible ' or ' extra-combustible '. It was assumed that combustibility of the paper itself was correlated with cigarette combustibility. Since then, the characteristics of cigarette paper, like natural porosity and burning additives, which influence truly cigarette combustibility, have been described by various authors and it became clear to cigarette designers that paper combustibility was not generally a significant factor governing cigarette combustibility. On the other hand, for Roll Your Own(RYO)wrapping papers, the ECPCI has proposed to the CORESTA RYO Task Force to use paper combustibility, and specially the LCT test, to classify papers between low and high smoke delivery, and a new Task Force on PAPER COMBUSTIBILITY was recently set up to develop a recommended method. The objective of this presentation Is to show results demonstrating that for paper used on cigarettes, there is NO GENERAL CORTRELATION between PAPER and CIGARETTE combustibility. We will also show results confirming that, for the specific group of RYO booklet papers containing no burning additives, there is a correlation between paper combustibility and FCSA's Combustibility/smoke delivery. This apparent discrepancy will be explained by reviewing the role played by the various characteristics of cigarette paper in governing cigarette combustibility.

New and innovative technologies for utilizing daylight in buildings have been developed for saving energies and improving visual environments. This study describes the most up-to date information available about the application and evaluation of advanced daylighting systems to enhance daylighting in non-residential buildings from IEA's Task 21. IEA's Task 21 consists on 4 subtasks such as "Performance Evaluation of Daylighting Systems(subtask A)", "Daylighting Responsive Controls(subtask B)", "Daylighting Design Tools(subtask C)" and "Case Studies(subtask D)". For the study, the configurations and characteristics of IEA's advanced daylighting systems are comparatively analyzed. As results, innovative daylighting systems are designed to redirect sunlight or skylight to areas which it is required without glare. These systems use optical devices that initiate reflection or refraction of sunlight and skylight. And they can be designed to actively track the sun or passively control the direction of sunlight and skylight. The comprehensive overview of innovative daylighting systems presented in this study helps designer to understand the advantages of daylighting in building and choose a suitable system for building in the earliest stage of the design process.

The purpose of present study was to investigate the characteristics of disfluency between the Korean-English bilingual and Korean monolingual children, matched by their chronological age with the bilingual children. Twenty-eight children, 14 bilingual children and 14 monolingual children participated in this study. The experimental tasks consisted of the play situation and the task situation. The conclusion is (a) The score of total disfluency of the bilingual was significantly higher than that of the monolingual. The score of normal disfluency of the bilingual was significantly higher than that of the monolingual. The most frequent type is Interjection in both groups. All shows higher score in the task situation than the play situation. The bilingual children have quantitative and qualitative differences in disfluency score and types from the monolingual. (b) The bilingual were divided into two groups such as 6 Korean-dominant bilingual and 8 English-dominant bilingual. All shows more disfluency in their non-dominant language. The most frequent type is Interjection in both groups. (c) The higher the chronological age and the expressive language test score is, the lower the disfluency score is. The earlier the exposure age to the 2nd language is, the higher the disfluency score is. There is no correlation between resident month at foreign country and the disfluency.

Purpose: The purpose of this study was to compare the tidal volumes and airway pressures of 3 mask-sealing methods (one hand C-E, two hands C-E, and one hand O-E) for ventilation treatment. Methods: The study subjects were 45 paramedic students. Tidal volume was measured for the three sealing methods by setting a ventilator, connecting it to the masks for 2 minutes, and using Respi-trainer software. Results: Regarding general characteristics, the group of men, in upper grades, and with practical training experience and experience and experience in the implementation of bag-valve-mask ventilation provided higher tidal volumes. Regarding physical characteristics, larger hands and greater grip strength correlated with higher tidal volume. Two hands C-E generated the highest tidal volume of $483.78{\pm}34.14mL$, one hand O-E generated $449.59{\pm}51.09mL$ and one hand C-E generated $394.31{\pm}68.95mL$. Conclusion: Means of tidal volumes were statistically significantly different based on mask sealing methods (p<.001). Two hand C-E was performed by the two-persons task and was suggested as the most effective method. For the one-person task, one hand O-E was the more effective method compared to the previous one hand C-E.

Quantum-Inspired Evolutionary Algorithm(QEA)은 알고리즘 자체에 충분한 data-level parallelism이 내재되어 있어 GPU를 이용한 가속에 용이하다. 그러나 효과적인 실행시간의 단축을 위해서는 CPU와 GPU에의 적절한 task-mapping이 필요하다. 이때 단순히 함수 자체의 병렬성만을 고려하는 것이 아니라 CPU와 GPU간의 데이터 전송도 고려하여 task-mapping을 할 필요가 있다. 또한 추가적인 성능향상을 위하여 zero-copy host memory와 적절한 execution configuration의 사용, 그리고 memory coalescing 등을 이용할 수 있다. 그 결과 30,000개의 item수를 가진 0-1 knapsack problem에 대한 QEA의 수행을 multi-threading CPU에 비해 평균 3.69배 빠르게 할 수 있었다.
