Urban Transit Train Radio is Radio Communication system that is used official business as leading motive for train safety running among the train crew and the central control center and drive-caring-chamber on main line and branch line. This system is operated that organizes talking path on handset of terminal after the train crew receives audio and understands call voice on speaker of terminal at calling the train of the central control center. When the central control center calls the specific train uses all call radio form, the train crew doesn't recognize the call cause the train situation, noise and action as train control. So there is a delay response cause reset call at the central control center. This research discusses the management of subway radio system and describes the call the train system that recognize train call number of all-call used between the central control center and the train crew.

The Korean population of the sword-tailed cricket subfamily Trigonidiinae is reviewed for the first time. Four members of the crickets are confirmed based on the examined material, those are Metioche japonica (Ichikawa, 2001), Svistella bifasciata (Shiraki, 1911), Homoeoxipha obliterata (Caudell, 1927) and Natula matsuurai Sugimoto, 2001, each of them belonging to a different genera. Among them, the former two are reconfirmed since earlier records, and latter two are newly recognized genera and species from the far southern provinces Jeollanam-do and Jeju-do Island in Korea. The type locality of both crickets is Japan, and are also only previously referred to in Japan, but their distributional ranges include neighboring South Korea. A key to the species, descriptions, photographs, figures, and oscillograms of male's calling sounds are provided to aid their identification.

The burrowing-cricket genus Velarifictorus Randell, 1964 is reviewed in Korea, comparing with morphologically resembled genus Lepidogryllus Otte and Alexander, 1983 for the first time. First, Velarifictorus aspersus borealis Gorochov, 1985 is confirmed from only restricted area of southern regions in Gyeongsangnam-do and Jeollanam-do. Second, Velarifictorus micado (Saussure, 1877) is confirmed from nearly all around the Korean peninsula including North Korea. Third, the previously not recorded Velarifictorus ornatus (Shiraki, 1911) is newly recognized from South Korea. Relating to the genus Velarifictorus, the resembled genus Lepidogryllus Otte and Alexander, 1983 and its species Lepidogryllus siamensis (Chopard, 1961) com. & stat. nov. is studied and compared with Velarifictorus members. A key, descriptions, tables, photographs, figures, oscillograms and spectrograms of calling sounds are provided to aid identification between the four similar species.

The hybrid neural networks have characteristics such as fast learning times, generality, and simplicity, and are mainly used to classify learning data and to model non-linear systems. The middle layer of a hybrid neural network clusters the learning vectors by grouping homogenous vectors in the same cluster. In the clustering procedure, the homogeneity between learning vectors is represented as the distance between the vectors. Therefore, if the distances between a learning vector and all vectors in a cluster are smaller than a given constant radius, the learning vector is added to the cluster. However, the usage of a constant radius in clustering is the primary source of errors and therefore decreases the recognition success rate. To improve the recognition success rate, we proposed the enhanced hybrid network that organizes the middle layer effectively by using the enhanced ART1 network adjusting the vigilance parameter dynamically according to the similarity between patterns. The results of experiments on a large number of calling card images showed that the proposed algorithm greatly improves the character extraction and recognition compared with conventional recognition algorithms.

Genetic algorithm is well known as a stochastic searching method. In this paper, a modified genetic algorithm using 'Suppor Vector Machines (SVM)' is proposed. SVM is used to reduce the number of calling the objective function which in turn accelerate the searching speed compared to the conventional GA.

Purpose: The purpose of this study was to analyze attitudes toward a successful life of students majoring in nursing science. Method: The Q-methodology which provides a method of analyzing the subjectivity of each items was used. The 32 selected Q-statements from each of 36 subjects were classified into a shape of normal distribution using a 9 point scale. The collected data was analyzed using a QUANL PC program. Result: Four types of successful life attitudes for research subjects in nursing science were identified. Type I is purpose achievement type, Type II is calling fullness type, Type III is balance maintenance type, and Type IV is happiness eagerness type. Conclusion: The results of the study indicate that different approaches to nursing professional education programs are recommended based on the four types of successful life attitudes.

Purpose: The aim of this study was to identify the influence of professionalism, role conflict and work environment in clinical nurses with expanded role (CNE) on job embeddedness. Methods: The participants in this study were 136 CNE working in general hospitals in Seoul, the wider metropolitan area and Gangwon Province. Results: Job embeddedness, work environment and professional performance of the participants showed positive correlation with each other. Significant predictors of embeddeness were belief in public service and sense of calling in the professional subcategory and participation in hospital affairs and nurse-doctor relationship in the work environment subcategory. Conclusion: Finding from this study indicate the need to evaluate and improve the significant predictors of job embeddedness for CNE.

The structure and variation of the mating call in Rana nigromaculata was studied in a population at Da-rak, Chong-won, Chung-buk (36$\circ$ 37' latitude, 127$\circ$ 21' longitude) in Korea. The mating call consists of 3 to 8 pulse groups divided by clear silent intervals. Each pulse group is also composed of fine pulses. Temperature and body size affect the temporal and spectral characteristics of the mating call. Pulse, pulse group repetition rate and dominant frequency rise with increasing temperature, whereas pulse grouprepetition rate and dominant frequency decrease with increasing body size. A playback experiment was designed to establish the effect of a potential intruder on male calling. During the stimulus periods, resident males markedly decreased the pulse repetition rate, and icreased the rate of pulse groups, dominant frequency, and the number of call groups. This results indicate that this species responds in a graded fashion when interacting with other individuals.

Objectives : The purpose of this study was to examine the correlation between the professionalism and job satisfaction of clinical dental hygienists. Methods : The subjects were 310 dental hygienists in private and group practiced dental clinics. A self-reported questionnaire was conducted from December, 2012 to February, 2013. Data were analyzed using SPSS WIN 12.0. Results : Dental hygienists revealed the highest score in a sense of calling (3.41) and the lowest score in professionalism (2.85). They showed the highest score in the relationship with dentists (3.56) and the lowest score in pay (2.83). Highly educated and aged dental hygienists wanted to get more clinical career as professionalist. So there was a very significant positive correlation between professionalism and job satisfaction. Conclusions : Dental hygienists showed job satisfaction. Therefore it is important to develop the linking system of professionalsim and human resources development program.

Code obfuscation is a technique that protects the abstract data contained in a program from malicious reverse engineering and various obfuscation methods have been proposed for obfuscating intention. As the abstract data of control flow about programs is important to clearly understand whole program, many control flow obfuscation transformations have been introduced. Generally, inlining is a compiler optimization which improves the performance of programs by reducing the overhead of calling invocation. In code obfuscation, inlining is used to protect the abstract data of control flow. In this paper, we define new control flow complexity metric based on entropy theory and N-Scope metric, and then apply genetic algorithm to obtain optimal inlining results, based on the defined metric.
