The purpose of this study was to examine the meaning and structure of the experience of female college students. For this purpose, 22 female college students, regardless of age, participated in the interview three times in total. Interview data were processed through the analysis and interpretation process using the phenomenological research method, Giorgi method. As a result, 34 semantic units were derived, then divided into 14 subcomponents, and then divided into 6 categories. As a result of analysis, the spiritual value of female college students was composed of "family", "friendly person", "professional person", "empathy", "reflection" and "trust". Based on the above meaning, the structure of the spiritual value of female college students can conclude that they were a continuation of life that forms a strong sense of value and empathy and trust with patience with family and friends. Based on this, intervention on spiritual well-being of female college students suggests that intervention to form values based on empathy and trust based on family and close friends is implemented.

In Korea, public infrastructure projects employ "long term continuation (LTC) contracts," which require budgets to be reevaluated and re-appropriated annually throughout the multi-year life of the project. However, such contracts also make it susceptible to frequently changing government policies, in which budgets required for existing projects are allocated to new projects and thus does not provide a consistent stream of capital to multi-year projects. Each year, the KEC needs to attain government funds for construction of its multiple highway construction sites. Because it is difficult to know the amount that may be actually appropriated to KEC in a given year, it is in turn difficult to anticipate and provide sufficient funds necessary for construction to run smoothly and continuously. The lack of a good logic for appropriation has resulted in projects having a skewed distribution of capital. To get better budget appropriations from the central government, the KEC first needs a systemized approach that rationalizes the annual construction capital optimally required for its individual sites. The goal of this research was to devise a way that allows the KEC to determine and calculate the optimal construction costs that would be required for its individual construction sites on an annual basis. Both the optimal progress rate and the essential work types were assessed through a workshop with 24 professionals (KEC employees and contractors) who had extensive experience in KEC projects and also were currently working in these projects.

Scrum is one of the most popular and efficient agile development methods. However, like other agile methods such as Extreme Programming (XP), Feature Driven Development (FDD), and the Dynamic Systems Development Method (DSDM), Scrum has been criticized because of lack of support to develop secure software. Thus, in 2011, we published research proposing the idea of a security backlog (SB). This paper represents the continuation of our previous research, with a focus on the evaluation in industry-based case study. Our findings highlight an improved agility in Scrum after the integration of SB. Furthermore, secure software can be developed quickly, even in situations involving requirement changes of software. Based on our experimental findings, we noticed that, when integrating SB, it is quite feasible to develop secure software using an agile Scrum model.

Most of automobile member parts experience severe springback problems because of their complicated shape and high yielding strength. Now it becomes imperative to develop an effective method to resolve these problems. However, there remain several obstacles to get accurate estimation of dimensional shape. Especially the effective algorithms to simulate sheet metal forming processes including drawing, trimming, flanging and springback is demanded for the multi stage simulation of automobile member parts. In this study, for the purpose of accurate springback calculation, a simulation program which is robust in springback analysis is developed. Favorable enhancement in computation time for springback analysis by using latest equation solving technique and robust solution convergence by continuation method are achieved with the program. In analysis, the multi processes of rear side member are simulated to verify the system. For the evaluation of springback accuracy practically, all conditions including boundary conditions for springback analysis and inspection conditions for dimensional accuracy are applied. The springback results of simulations show good agreement with the experiments.

The current study is a part of series o research about the development of new superstructure system to overcome the engineering problems in the design of bridges of 30m to 45m in span length using the existing bridge systems. The basic concept of new system is the continuation of adjacent tow simple spans composed of the precast prestressed concrete U-type sections. The partial post tensioning method is applied to create the continuity. In this study, the new technique was introduced and applied with an example design of tow span of 40m in span length to find the possibility for practical application as the feasibility study. The obtained results show that the new splicing method is expected to offer significant economical and serviceability advantages.

Conventional decoding procedures have some problems in order to obtain reconstructed images with high speed. In this paper, the solutions of these are studied and a new fast decoding algorithm is proposed. The proposed algorithm uses a convergence criterion that is used to reduce the redundant iteration in the conventional method and to determine continuation of decoding. The initical image similar to roiginal image is estimated firstly in this algorithm. From the simulation resuls, the proposed algorithm is able to achieve the reconstructed image within 3-4 iteration under the objective criterion. Without any increment of the memory, the quality of the image reconstructed by the proposed algorithm has same quality asthe conventional method.

This paper presents an algorithm that evaluates load supplying capability(LSC) considering voltage constraint in composite power systems. To evaluate the LSC considering the voltage constraint, we apply tangent vector approach using an enhanced power flow method based on continuation algorithm. The validity and effectiveness of the proposed method is confirmed through the simulation of a model system.

This paper presents a method based on neural networks to detect the broken rotor bars and end rings of squirrel cage induction motors. At first, detection methods are studied, and then traditional methods of fault detection and dynamic models of induction motors by using winding function model are introduced. In this method, all of the stator slots and rotor bars are considered, thus the performance of the motor in healthy situations or breakage in each part can be checked. The frequency spectrum of current signals is derived by using Fourier transformation and is analyzed in different conditions. In continuation, an analytical discussion and a simple algorithm are presented to detect the fault. This algorithm is based on neural networks. The neural network has been trained by using information of a 1.1 KW induction motor. This system has been tested with a different amount of load torque, and it is capable of working on-line and of recognizing all normal and ill conditions.

The Radial Point Interpolation Method (RPIM) has been proposed to overcome the difficulties associated with the use of the Radial Basis Functions (RBFs). The RPIM has the following properties: Simple implementation in terms of boundary conditions as in the Finite Element Method (FEM). A less expensive CPU time compared to other collocation meshless methods such as the Moving Least Square (MLS) collocation method. In this work, we propose an adaptive high-order numerical algorithm based on RPIM to simulate the thermoviscoplastic behavior of a material mixing observed in the Friction Stir Welding (FSW) process. The proposed adaptive meshfree RPIM algorithm adapts well to the geometric and physical data by choosing a good shape parameter with a good precision. Our numerical approach combines the RPIM and the Asymptotic Numerical Method (ANM). A numerical procedure is also proposed in this work to automatically determine an improved shape parameter for the RBFs. The efficiency of the proposed algorithm is analyzed in comparison with an iterative algorithm.

Purpose: The objective of this study was to identify the effectiveness of continued breast feeding and maternal identity between rooming-in and not rooming-in groups of mothers in post partum care. Method: The subjects were selected by convenient sampling, with 95 women in childbirth completing a questionnaire. The data were collected on the 2nd day after delivery by questionnaire, and after the 4th and 8th weeks by telephone interview. Measures used in this study included general characteristics, breast feeding related characteristics, and the maternal identity scale revised by Koh(1996). The data were analyzed with the SPSS program, and the Chi-test and t-test were used to identify the effect on breast feeding and maternal identity. Results: Continued breast feeding up to 4 weeks after deliverly was not statistically significant between rooming-in and not rooming-in group, but beyond 8 weeks of deliverly, it was significantly different in rooming-in group(p<.01). Maternal identity was significantly higher in rooming-in group than in not rooming-in group(<.01). Conclusion: Mothers preferred rooming-in system because it helped breast feeding and baby care. Rooming-in system provides self confidence in taking care of baby, knowledge about breast feeding and stimulates early phase lactation. We recommend rooming-in system in hospitals to promote breast feeding and maternal identity. Nurses are encouraged to discuss prenatal breast feeding before delivery and rooming-in care should be planned individually for continuation of breast feeding and formation of maternal identity.
