  • Purpose: The purpose of this study was to identify and describe nurses' experience of a career ladder program (CLP) in a general hospital in Korea. Methods: The data were collected from 15 nurses who participated in the CLP. Each nurse completed individual in-depth interviews, for which the main interview question was "How do you describe your experience of CLP?" All interview data were transcribed and were analyzed using the grounded theory method. Results: The core category of the experience of CLP was identified as "challenging to rebirth as an expert". The participants used five action/interaction strategies such as "taking some time for introspection", "appreciating the essence of nursing", "making use of feedback positively", "throwing away doubts about their own capabilities", "exerting themselves with confidence". The consequence of the process of adjusting to CLP was "positioning a differentiated expert". Conclusion: The results of this study show that participants recognized CLP as a powerful resource which leads them to professional growth and development. Thus, CLP could be utilized as a clinical career-promoting program and ultimately as a program for providing high-quality nursing services.

  • This paper aims at the comparative study of practicing Buddhism and Taoism related to "life gate". The term "life gate", as a physiological entity of disputed morphological identity, first appears in The Inner Canon where it refers to the eyes. Reference to a "life gate" as an internal organ body first appears in The Classic of Difficult Issues which states, "The two kidneys are not both kidneys' The left one is the kidney, and the right is the life gate." Successive scholars refers to life gate as a gi point of Taoists.. The question of the life gate invited little discussion until the Myeong and Cheong Dynasty, when various different theories were put forward. Especially Jin Sa-taek says "life gate" is the governor of the twelve place in the human body, throwing light on the meaning of it. Not that life gate denotes a local point, it does a system of life gate. Generally speaking, life gate designates cinnabar field. I think that the human body produces essence by way of life gate. That is, the human body is unified by the system of life gate. Life gate is not only the source of infusing the engine of the human body with vital energy but also as well as gi-point.

  • We present a fully homomorphic encryption (FHE) scheme without key switching based on ring- learning with errors (RLWE) problems and some other assumption. Previous FHE schemes based on LWE needed a step called key switching to reduce the dimension of ciphertext. The key switching step actually needs a heavy computation and severe increasement of keys. So the key switching step is a big burden for implementing FHE Schemes. We suggest a FHE scheme without key switching step by reducing the dimension of ciphertexts in other way. Instead of throwing away key switching, we need another hardness assumption of the difficulty of solving quadratic equation over rings.

  • Lesion of the superior glenoid labrum and the insertion of the biceps tendon are a common cause for shoulder pain in patients performing overhead sports. Medial shearing stress during overhead throwing may cause biceps instability and associated rotator cuff problem aggravates the symptoms. Careful attention to the history and physical examination and may arouse suspicion of injury to the biceps tendon and the superior labral complex. Progress in shoulder arthroscopy has led to the identification of the lesion and normal variation. Treatment should be directed according to the type of lesion and related symptoms.

  • The purpose of this study is to test and compare the efficiency of heating-system for materials and construction of the wall, ceiling and window in soil brick house, cement house and boulder house respectively, in order to construct ideal farm houses in rural area. The results obtained were as follows: 1. In heat conservation due to construction of walls the thermal efficiency of cement brick house was equivalent to 66.3% of that of soil brick house, and boulder house 60.3% 2. In the case of ceiling, the thermal efficiency of paper ceiling was amounted to 84.2% of that of the composite ceiling (thickness 6mm veneer+thickness. l0m chaffs), and the common ceiling putting on soil above the ceiling, 76% of the composite while the efficiency of the ceiling putting on chaffs above them was 15.8% higher than that of the paper. 3. In the case of improving the window, the double type was 12% higher than. the efficiency of single type. 4. The warming velocity of conventional house was slower but the velocity of radiation was quicker than that of experimental one. It was thought to be due to unscietific constructions of the room bottom, fire inlet and chimney, 5. The temperature gradient line was not dependad upon the amount of throwing into fuel in the rural farm house. 6. It was concluded that the final thermal efficiency of the conventional farm house was 10.6% lower than that of experimental farm house.

  • This study was conducted by the slump test and the consistency test of the cement mixed soil which is soil mixed with cement to investigate and estimate the difficulty degree of work and the proper water content. So I would like to present the fundamental data that establish the work standard of the cement mixed soil. In conclusion, in this study the slump value of the cement mixed soil increases over-all according to the increase of the water content although it has a little difference of the increase range and it is smaller than one of the soil. It is estimated that the aggregating and throwing work of the cement mixed soil which is mixed with 6% and 9% cement would be fine when it has the $25%{\sim}27%$ water content and the wall plastering work is the $30%{\sim}32%$ and the floor plastering work is the $30%{\sim}35%$ and the flowing and pouring work is the $40%{\sim}42%$ water content as well as the mold compacting work is the 20%.

  • In order to study the effect of student's conceptions about force and motion into the graph construction in kinematics in college physics course, the tasks of constructing the qualitative graph in the similar problem context used in force conception was asked to the first 74 and third 97 student teacher in teachers' university. The frequencies analysis showed that student teachers had the naive conceptions that the throwing force was still acted to a upwarding ball. They also had the popular Aristotelian views about motion. These naive conceptions coexisted with the scientific conception about gravitational force. In a simple pendulum problem no one had the correct acceleration concepts which varies the direction in swing. This result suggest that student teacher had more difficulties in a acceleration problem than in a velocity problem In v-t and a-t graph construction tasks, the number of categories of a-t graphs were more than that of v-t graphs. There were many graph errors in a sign of velocity and acceleration. The acceleration conceptions without the relations of changes in velocity made the kinematics graphs more various shapes. The force and motion conceptions influenced the ability to construct the kinematics graphs.

  • A virtual reality is a virtual space constructed by a computer that provides users the opportunity to indirectly experience a situation they have not experienced in real life through the realization of information for virtual environments. Various studies have been conducted to realize virtual reality, in which the user interface is a major factor in maximizing the sense of immersion and usability. However, most existing methods have disadvantages, such as costliness or being limited to the physical activity of the user due to the use of special devices attached to the user's body. This paper proposes a new type of interface that enables the user to apply their intentions and actions to the virtual space directly without special devices, and test content is introduced using the new system. Users can interact with the virtual space by throwing an object in the space; to do this, moving object detectors are produced using infrared sensors. In addition, the users can control the virtual space with their own postures. The method can heighten interest and concentration, increasing the sense of reality and immersion and maximizing user's physical experiences.

  • Exploitation of renewable energies is on the increase to mitigate the reliance on fossil fuels and other natural gases with rocketing prices currently due to the depletion of their reserves not to mention their diverse consequences on the environment. Divergently, there are lots of industries "throwing" heat at higher temperatures as by products into the environment. This waste heat can be recovered through organic Rankine systems and converted to electrical energy with a waste heat recovery organic Rankine cycle system (WHR-ORC). This study uses the annual average condenser effluent from Namhae power plant as heat source and surface seawater as cooling source to analyze a waste heat recovery organic Rankine cycle using the Aspen HYSYS simulation software package. Hydrocarbon mixtures are employed as working fluid and varied in a ratio of 9:1. Results indicate that Pentane/Isobutane (90/10) mixture is the favorable working fluid for optimizing the waste heat recovery organic Rankine cycle at the set simulation conditions.
