Purpose: The purpose of this qualitative study was to explore the meaning of the experience of Korean immigrant nurses working in US hospitals. Methods: Purposive sampling yielded 15 Korean immigrant nurses who had more than one year of clinical experience in US hospitals. Data were collected from March to August 2012 through in-depth interviews and thematic analysis was conducted using van Manen's hermeneutic phenomenological approach. Results: The findings were classified into eight themes: 'struggling from staff at workplace being territorial to outsiders', 'feeling oppressed due to language barrier', 'accepting rational and horizontal relationships at work', 'staying alert in the environment where lawsuits are rife', 'feeling a sense of stability from the social system that values human dignity', 'maintaining self-confidence from prominent nursing practices and senior Korean nurses' professional reputation', 'performing essential comprehensive nursing care', 'promoting self-development to be equipped with professionalism.' Conclusion: The findings indicate that the Korean immigrant nurses were able to excel in their workplace when their clinical experience at US hospitals was combined with the lived space in US politics and environment, lived time of patience, lived body to be alert, and lived others with multi cultural characteristics.

The aim of this study is to provide practical instances of implementing picture book reading sessions within school libraries to enhance language proficiency and foster emotional stability among lower-grade multicultural students hailing from foreign backgrounds. The research outlines the design and execution of a picture book reading program tailored for multicultural students, with analysis based on the outcomes of actual classroom implementations. In the course of the study, existing literature pertaining to the use of picture books for enhancing multicultural education and language skills was reviewed. This informed the development of a structured class procedure by extracting core components. Indeed, 43 multicultural students in five classes in the first and second grades of A Elementary School in Gyeonggi-do were given three pilot classes for each class for 20 weeks and a total of 100 picture book reading classes, each with 17 main lessons. This study establishes the positive impact of picture book reading classes on the Korean language comprehension of multicultural students. The results confirm positive improvements in students' ability to understand Korean, as evidenced by enhanced Korean expression and presentation skills, increased library usage, and a positive shift in classroom attitude. The procedure for reading picture books using school libraries proposed in this study was actually conceived and developed in the course of class operation in the school education field, reflecting the changes brought about by the increase of multicultural students and the need to improve the class environment. Through this practical investigation, important insights have been extracted regarding how picture book reading sessions designed for elementary school students from multicultural backgrounds can enhance the classroom environment and elevate learning outcomes.

Dynamic analysis is necessary for the High-Speed Railway vehicle which aims to run on max 400km/h. Especially, dynamic simulation using CAE(Computer Aided Engineering) can help to reduce the time of development of the High-Speed Railway vehicles. Also, it helps to reduce prices and improve the quality such as safety, stability and ride. There are many dynamic software for a railway vehicle, such as Vampire and ADAMS-Rail. There are limitations for each software and difficulties to analyze overall dynamics for entire railway system. To overcome these limitations, in this study, a program which can simulate entire railway vehicles was developed. This program is easy to use because it was developed using C++, which is object-oriented programming language. In addition, the basic platform for the development of dynamic solver is prepared using the nodal, modal coordinate system with a wheel-rail contact module. Rigid, flexible and large deformable body systems can be modeled by a user according to the characteristic of a desired system. Its reliability is verified by comparison with a commercial analysis program.

The advent of the era of data age and advances inartificial intelligence technology has led to innovations in various business areas. In particular, many attempts have been made to improve the stability of the marine accident, which has not previously been applied by a data-drive approach. Most of the marine accidents happen at a time when the vessel isapproaching a port and preparing for berthing. Although the cause of the accident has many factors, it is often caused by the difficulties of communication between the ship navigator and the control center. In particular, communication in English makes difficulties for navigators, not English astheir first language. To do this, proper English conversation education forsailors is very important. In order to support the issue, this study presents data and framework for the development of a chatbot for ship safety education.

In this paper, a remote submersion warning system based on multi-mode optical fiber(MMF) sensors and a wireless sensor network(WSN) are proposed. To improve the reliability and stability of the sensors, the dual optical fiber sensors combined to the optical coupler are demonstrated. A slave zigbee as a wireless sensor module was used as a platform to monitor and record the signal from the MMF sensors and then transmits these information to a master zigbee wirelessly. The monitoring system running the $LabVIEW^{(R)}$ software was connected to the internet to support the short message service(SMS) through extensible markup language(XML) web service. No matter where the managers are, they can always receive the real-time remote-monitoring data for safety check.

Painting, as an artistic creation with aesthetic characteristics, is inseparable from "shape". "Modeling" is a subjective way of expressing objects, and "black shape" is not only a way of expression, but also a way of composition. "Black shape" is a way of expressing the overall picture of the creator, and "black shape" extracted from the pattern analysis of black and white gray structure is a powerful means to deeply explore the emotions and thoughts of the painter. How to create the expression of subjective intention in the creation of artificial figure painting and to explore the beauty of picture form and the presentation of formal language in multiple dimensions is always sought by painters. Tang Dynasty political stability, economic and cultural development of unprecedented prosperity, "Toujian Diu" as a representative painting of Tang Dynasty, the figure is plump and realistic, colorful but elegant. It not only represents the aesthetic taste of the Tang Dynasty, but also reflects the overall style of the Tang Dynasty's artificial figure painting. The aim of this paper is to explore the value of "black shape" in "Toughen Diagram" and analyze its multi-component form in depth.

Efficiency for estimation of subsea tunnel safety can be increased through reflecting back analysis algorithm to displacement measurements besides other measurement information such as stress, water pressure and ground stiffness degradation. In this study, the finite difference code FLAC3D built-in FISH language is used. In addition, the stability of the tunnel lining will be evaluated from the development of displacement-based algorithm and its expanded algorithm with conformity of several parameters such as stress measurements, water pressure measurements, tunnel lining degradation measurements and ground stiffness degradation measurements. By using additional measurement information to assess the stability of subsea tunnel, it was confirmed that the error rate is reduced to the tunnel back analysis.

Estimation of the stability of an operating tunnel through a back analysis is a difficult concept to analyze. Specially, when a relatively thick lining is constructed as in case of a subsea tunnel, there will be a limit to the use of displacement-based tunnel back analysis because the corresponding displacement is too small. In this study, DEA is adopted for tunnel back analysis and the feasibility of DEA for back analysis is evaluated. It is implemented in the finite difference code FLAC3D using its built-in FISH language. In addition, the stability of a tunnel lining will be evaluated from the development of displacement-based algorithm and its expanded algorithm with conformity of several parameters such as stress measurements.
