Purpose: The purpose of this study was to examine clinical competence and organizational socialization according to communication style of preceptors as perceived by new nurses. Methods: From May 1 to July 31, 2014, data were collected from 180 new graduated nurses who had been working for 3~12 months in hospitals in Busan and one in Gyungnam. Data were analyzed using descriptive statistics, t-test, ANOVA, and Pearson correlation coefficients. Results: Preceptors's communication style perceived by the new nurses included supportive type, reflective type, emotive type, and directive type in order of precedence. The average score for clinical competence was $2.82{\pm}0.31$, and the average score for organizational socialization was $3.05{\pm}0.40$. There were significant differences in nurses' clinical competence(F=9.087, p<.001) and organizational socialization (F=30.129, p<.001) according to preceptor's communication style. Conclusion: Results indicate that supportive and emotive communication styles of preceptors were important factors in the success of the preceptees' clinical competence and organizational socialization.

In this paper, we propose Adaptive Writeback-aware Cache management (AWC) to prolong the lifetime of non-volatile main memory systems by reducing the number of writebacks. The last-level cache in AWC is partitioned into Least Recently Used (LRU) segment and LRU using Dirty block Precedence (DP-LRU) segment. The DP-LRU segment evicts clean blocks first for giving reuse opportunity to dirty blocks. AWC can also determine the efficient size of DP-LRU segment for reducing the number of writebacks according to memory access patterns of programs. In the performance evaluation, we showed that AWC reduced the number of writebacks up to 29% and 46%, and saved the energy of a main memory system up to 23% and 49% in a single-core and multi-core, respectively. AWC also reduced the runtime by 1.5% and 3.2% on average compared to previous cache managements for non-volatile main memory systems, in a single-core and a multi-core, respectively.

Offline-based study is proceeding effectively for directly teaching and communication between a learner and a professor. In general virtual education system have been solve this problem using provides search of particular learning domain and auto feedback of relative learning domain after examination. But the learner needs personally select the right document among search result set and interconnected precedence study domain. Therefore, the unskilled learner is difficult of learning progress over against offline-based study. This paper suggests a index mechanism of varied views for helps to learner understand the flow and direction of learning and correlation between units.

Japanese encephalitis is the leading cause of viral encephalitis in Asia, where it accounts for up to 50,000 cases. Approximately 20% of affected patients die, and 30-50% of survivors have significant neurological sequelae. Inactivated mouse-brain derived Japanese encephalitis vaccines has been effectively implemented to control the disease effectively in Korea and several other Asian countries. However, the vaccine is expensive and difficult to produce, requires multiple doses, and has been associated with hypersensitivity reactions and rare adverse neurologicale events. The live-attenuated SA14-14-2 vaccine derived from primary hamster kidney (PHK) cells was developed in China and has been used there since 1988. Outside China, it has been licensed and used in Korea and several other Asian countries. This vaccine is effective and inexpensive. However, the lack of precedence for using a PHK cell substrate in a live-attenuated vaccine is a special issue of concern. The WHO working group has recommended additional safety studies in selected high-risk groups, as well as ongoing post-marketing studies to ensure long-term safety. Recently, a new inactivated vaccine and live-attenuated chimeric vaccine have been developed from vero cells. With this background, this article summarized the current status of Japanese encephalitis vaccination worldwide and in Korea.

The purpose of this study is to reviews the Chinesm expressed in the modern fashion world after the year 2000, and underlines the characteristics of Chinesm, as the Chinese fashion market is getting bigger and becomes the cynosure of the world. The method of this study is by research on precedence as well as related researches in Korean and foreign books. The results were as follows. First, the Chinesm recreates the historic motive which is the traditional costume, ornaments, or make-up etc. to maintain the harmony between the modernity and the past, preventing from following or mimicking. Second, the Chinesm expresses the combinational and harmonious manner with the combined image on the Chinese original symbolic factors mixing with the foreign spatial-temporal elements, the various styles of wear and decoration, and the different images to have the natural or equivocal relationship with one another. Third, The Chinesm magnifies the feminine atmosphere to express the sensual image by using effectively the traditional design factors, which is tight silhouette, coverture, and exposure. Fourth, the Chinesm professes the pro-naturalism embracing the human without conflicting with the human nature. It seems possible on the new value mixed with colors, materials, or patterns, etc.

Research on the flow shop model has mainly been centered around periodic tasks scheduling. In this paper, we present an algorithm using synthetic utilization that can check the schedulability of aperiodic local tasks and aperiodic end-to-end tasks with precedence relation in the flow shop model. If the scheduling algorithm for aperiodic end-to-end tasks executed in the multiple stage pipeline is applied to the flow shop model, sometimes the actually schedulable tasks are decided to be not schedulable because of the fact that the actually unschedulable tasks are decided to be schedulable. The algorithm presented in this paper solves the problem, and the simulation shows that the schedulability increases 10%.

This study investigates the acoustic property of aspiration realized in English voiceless stops of /Cr/ and /sCr/ clusters. VOT is measured from stops in these clusters produced by two groups; one from native speakers of English and the other from Korean native speakers. Aspiration of stops in different types of clusters is compared to various phonological factors such as location of stress, syllable type, and position in word. Pursuing the idea that phonetic realization is correlated with phonological representation, attempts are made to account for the gradient nature of aspiration of stops on the basis of syllable structure at the phonetic level, which may vary in the wake of resyllabification. Voiceless stops in /Cr/ and /sCr/ clusters are further compared to results obtained in the previous study on /sC/ cluster. Variations in aspiration are also characterized in terms of segmental precedence relation of stops in the clusters, namely, post-[s], pre-[r], or both.

This paper deals with a multiobjective process planning problem of flexible assembly systems(FASs). The FAS planning problem addressed in this paper is an integrated one of the assignment of assembly tasks to stations and the determination of assembly routing, while satisfying precedence relations among the tasks and flexibility capacity for each station. In this research, we consider two objectives: minimizing transfer time of the products among stations and absolute deviation of workstation workload(ADWW). We place emphasis on finding a set of diverse near Pareto or true Pareto optimal solutions. To achieve this, we present a new multiobjective coevolutionary algorithm for the integrated problem here, named a multiobjective symbiotic evolutionary algorithm(MOSEA). The structure of the algorithm and the strategies of evolution are devised in this paper to enhance the search ability. Extensive computational experiments are carried out to demonstrate the performance of the proposed algorithm. The experimental results show that the proposed algorithm is a promising method for the integrated and multiobjective problem.

Disassembly of discarded products takes place in the process of remanufacturing, recycling, and disposal. The disassembly lines have been taken as available choice for automated disassembly; therefore, it has become essential that it be designed and balanced to work efficiently. The multi-objective disassembly line balancing problem seeks to find a disassembly sequence which provides a feasible disassembly sequence, minimizes the number of workstations and idle time, and balances the line for the disassembly of post consumed product by considering the environment effects. This paper proposes a multi-criteria decision making technique based heuristic for assigning the disassembly tasks to the workstations. In the proposed heuristic, the PROMETHEE method is used for prioritizing the tasks to be assigned. The tasks are assigned to the disassembly workstations according to their priority rank and precedence relations. The proposed heuristic is illustrated with an example, and the results show that substantial improvement in the performance is achieved compared with other heuristics.
