The purpose of this study is to develop a communication model of teaching-learning at culinary practical learning class in school. Statistically, the organizational culture of culinary schools was influenced by the nature of hierarchical culture, task outcomes, and the conservative culture of organizations in companies. First, in basic skill class, teaching and learning methods are based on a teacher who leads students according to his plans and decisions. Second, in a higher skill course, teaching and learning methods are based on students who take an active part by injecting some fresh ideas into their class. Third, the model of three courses for culinary skill development has an effect on processing into a modeling-scaffolding-fading method by teaching and learning in school. It was ascertained that organizational culture directly or indirectly influenced organizational effectiveness and organizational culture in culinary schools. Moreover, it was found that organizational culture was the biggest influencing concept for communication effectiveness between teachers and students.

In order to prevent drink-driving by detecting concentration of alcohol from driver's exhale breath, twenty chemical sensors fabricated. The one of purposes for sensor array which consists of those sensors is to discriminate between target gas(alcohol) and interference gases($CH_3CH_2OH$, CO, NOx, Toluene, and Xylene). Wilks's lambda was presented to achieve above purpose and optimal sensors were selected using the method. In this paper, step-wise sensor elimination based on Euclidean distance was investigated for selecting optimal sensors and compared with a result of Wilks's lambda method. The selectivity and sensitivity of sensor array were used for comparing performance of sensor array as a result of two methods. The data acquired from selected sensor were analyzed by pattern analysis methods, principal component analysis and Sammon's mapping to analyze cluster tendency in the low space (2D). The sensor array by stepwise sensor elimination method had a better sensitivity and selectivity compared to a result of Wilks's lambda method.

Most available methods of facial gender recognition work well under a constrained situation, but the performances of these methods have decreased significantly when they are implemented under unconstrained environments. In this paper, a method via low-rank and collaborative representation is proposed for facial gender recognition in the wild. Firstly, the low-rank decomposition is applied to the face image to minimize the negative effect caused by various corruptions and dynamical illuminations in an unconstrained environment. And, we employ the collaborative representation to be as the classifier, which using the much weaker $l_2-norm$ sparsity constraint to achieve similar classification results but with significantly lower complexity. The proposed method combines the low-rank and collaborative representation to an organic whole to solve the task of facial gender recognition under unconstrained environments. Extensive experiments on three benchmarks including AR, CAS-PERL and YouTube are conducted to show the effectiveness of the proposed method. Compared with several state-of-the-art algorithms, our method has overwhelming superiority in the aspects of accuracy and robustness.

This thesis describes the effective interfacing methods of PACS Modality based on the system installation andoperating experiences. PACS(Picture Archiving and Communication Systems) is a system for medical image archiving and communication using large storage device and high-speed network. The standard communication protocol of PACS is DICOM(Digital Imaging and Communication in Medicine) based on TCP/IP and point-to-point protocol. However, there are many Non-DICOM Modalities and DICOM Modalities having problems. First, we had interfaced almost modalities. Fuji CR, GE CT, MRI, Angio, Fluoro, Phillips Angio, Shimadzu Fluoro. Ultrasound PACS, with the main PACS in the Seoul S Hospital as large scale hospital. And we manipulated the intelligent image distribution and the CT. MRI Interfaces never experienced beforein the Anyang J Hospital and the Chungju C Hospital as mid or small scale hospital. Technically, we developed both the DICOM Interface and the Non-DICOM Interface. At the last, the DICOM Worklist and the DICOM Print Interface were implemented in the Seoul B Hospital, the Bucheon SJ Hospital and the Seoul K Hospital independently with PACS. The Oracle, Sybase and MS-SQL are used as database, and UNIX, Macintosh, MS Windows as operating systems. And the Visual C++ and UNIX C are the main programming tools. We have used UTP, coaxial and fiber optic cable under 10/100 mbps LAN for networking.

Purpose: The purpose of this study was to identify the predictors of job stress in hospital nurses. The predictors of job stress were the subject's general characteristics, communication style, critical thinking disposition and job satisfaction. Methods: 294 nurses who had worked in a hospital participated in this study. The data were analysed with descriptive analysis methods including a t-test, ANOVA, Scheffe test, Pearson correlation coefficient and multiple regression analysis. Results: The job stress score for nurses was 111.6. There was a statistically significant difference between job stress and marriage status (p<.001), education (p<.001), clinical career (p<.001), position (p<.001), communication style (p<.001), critical thinking disposition (p<.001), and job satisfaction (p<.001). Critical thinking disposition, job satisfaction and clinical career together accounted for 36.88% of the total variation in job stress. Conclusion: Based on the findings of this study, the development of a nursing intervention program that can lead to an improvement in critical thinking disposition is suggested.

The purpose of this study was to identify the relationship between complexity, tacit knowledge, know-how, perception, and perception on business performance, and to suggest management implications for corporate performance and organizational executives. Therefore, the implications of this study are as follows. First, corporate representatives and staff in charge of organization should be able to access various information and contents through various routes about the work of members of the organization, and should make efforts to freely communicate among members. Second, corporate representatives and organizational practitioners should consider using the traditional methods of communication within their work, but allowing more informed and inmates to do more off-the-job activities that can increase intimacy with each other. Third, corporate representatives and organizational practitioners should provide a situation in which they can acquire work knowledge in a variety of ways, but must devise communication methods to increase information sharing and information value among members. Fourth, corporate representatives and organizational practitioners should endeavor to provide employees with educational support, family invitation events, awards and bonuses, and compliments that will make them more interested in their work. Lastly, corporate representatives and organizational practitioners are encouraged to maintain effective communication, employee pride, etc., so that the concentration of work, achievement, quality and productivity of work, and high professionalism can be maintained.

Objectives: This study aimed to examine the general tendencies of women's divorce intention and to analyze the related variables that affect women's divorce intention. It would help explore the conditions for prevention or intervention of divorce. Methods: For this purpose, the structured survey was conducted by 521 married women aged between 20 and 70 living in Jeollanam-do and Gwangju. The data was analysed by SPSS 21.0 program. Results: First, the average score of divorce intention was 2.04, which was lower than the middle. The average score of self-differentiation, marital communication efficiency, reasonable coping, and social support were a bit higher than the median score. Second, the differences in the divorce intention according to the academic background and household income were statistically significant. Third, marital communication efficiency had the biggest effect on divorce intention and it was followed by avoidance-oriented behavior, reasonable coping, support from the local community, self-differentiation, and household income. Conclusion: It is very important to understand the various factors related to divorce intention especially in individual, marital, social aspects. In addition, it is actually required to develop the couple programs about coping strategies, effective couple communication and problem-solving methods. It also have to imply the requirements considering psychological, social aspects such as self-differentiation and social support.

The error-rate floor of low-density parity-check (LDPC) codes is attributed to the trapping sets of their Tanner graphs. Among them, fully absorbing sets dominantly affect the error-rate performance, especially for short blocklengths. Efficient methods to identify the dominant trapping sets of LDPC codes were thoroughly researched as exhaustively searching them is NP-hard. However, the existing methods are ineffective for Raptor-like LDPC codes, which have many types of trapping sets. An effective method to identify dominant fully absorbing sets of Raptor-like LDPC codes is proposed. The search space of the proposed algorithm is optimized into the Tanner subgraphs of the codes to afford time-efficiency and search-effectiveness. For 5G New Radio (NR) base graph (BG) 2 LDPC codes for short blocklengths, the proposed algorithm finds more dominant fully absorbing sets within one seventh of the computation time of the existing search algorithm, and its search-effectiveness is verified using importance sampling. The proposed method is also applied to 5G NR BG1 LDPC code and Advanced Television Systems Committee 3.0 type A LDPC code for large blocklengths.

In Korea, we still use function point based cost estimations for software size and cost of a project. The current problem is that we make difficultly calculating function points with requirements and also have less accurate. That is, it is difficult for non-experts to analyze requirements and calculate function point values with them, and even experts often derive different function points. In addition, all stakeholders strongly make the validity and accuracy of the function point values of the project before /after the development is completed. There are methods for performing function point analysis using source code [1][2][3][4] and some researchers [5][6][7] attempt empirical verification of function points about the estimated cost. There is no research on automatic cost validation with source code after the final development is completed. In this paper, we propose automatically how to calculate Function Points based on natural language requirements before development and prove FP calculation based on the final source code after development. We expect validation by comparing the function scores calculated by forward engineering and reverse engineering methods.
