The purpose of this study was to explore to what extent mothers and fathers differ in their disciplinary practices and to examine the relationships between quality of life and the parental disciplinary practices. The subjects of this study consisted of 220 parents(220 mothers and 220 fathers) of 5-6 years of children in Pusan. Descriptive analysis, correlation analysis, t-tests were used for data description and analysis. The major results were as follows: 1. There was a positive relationship between perceived quality of life by fathers and perceived quality of life by mothers. 2. There was a difference between fathers and mothers in relation to perceived quality of life. Fathers perceived their quality of life more highly than did mothers. 3. There were positive relations between parental educational level, household income and quality of life. 4. There were differences between fathers and mothers in relation to disciplinary practices. Fathers exhibited more effective disciplinary practices(including less overreactiveness and less verbosity) than did mothers. 5. There were no relations between parental educational level and disciplinary practices, but household income was only related to maternal disciplinary practices. 6. There were positive relations between quality of life and disciplinary practices. The higher parents perceived their quality of life, the more parents exhibited effective parental disciplinary practices.

Thise study is designed to demonstrate the influence of socio-demographic variables(age, education, career history and marital Status), alexithymia, burnout, and adult attachment on child disciplinary styles; childcare teachers in charge of young children were studied. The purpose of the study is to provide information about the desirable disciplinary styles of a childcare teacher in order to strengthen the quality of childcare education. The data collected in this study showed the following results: First, the age, education, career history and marital status of a teacher produced good results statistically irrelevant to the their child disciplinary style. Second, a high level of negative correlation was found among alexithymia, burnout, adult attachment and the child disciplinary style of a childcare teacher. In other words, if a teacher shows a high level of alexithymia, burnout, and adult attachment, it is likely that the teacher's child disciplinary style is coercive and neglect, and the teacher tends to give an illogical explanation. Third, in contrast to the other variables, burnout and adult attachment have a greater effect on child disciplinary style than alexithymia.

Many researchers have recently studied multi-level formulation strategies to solve the MDO problems and they basically distributed the coupling compatibilities across all disciplines, while single-level formulations concentrate all the controls at the system-level. In addition, approximation techniques became remedies for computationally expensive analyses and simulations. This paper studies comparisons of the MDO methods with respect to computing performance considering both conventional sequential and modem distributed/parallel processing environments. The comparisons show Individual Disciplinary Feasible (IDF) formulation is the most efficient for sequential processing and IDF with approximation (IDFa) is the most efficient for parallel processing. Results incorporating to popular design examples show this finding. The author suggests design engineers should firstly choose IDF formulation to solve MDO problems because of its simplicity of implementation and not-bad performance. A single drawback of IDF is requiring more memory for local design variables and coupling variables. Adding cheap memories can save engineers valuable time and effort for complicated multi-level formulations and let them free out of no solution headache of Multi-Disciplinary Analysis (MDA) of the Multi-Disciplinary Feasible (MDF) formulation.

Marine accidents and legal violations result from mistakes and negligences of ship officers, deck officers and engine officers, during the ship navigation and lay days. Due to these accidents and violations, these officers are subjected to disciplinary actions for certification. The disciplinary action, namely certificate punishment is carried out by right rules, processes and equity. However, it is revealed that present situations are different from the principles. For the purpose of finding current states relating to certificate punishment, this study examines and analyses 737 punishment cases, accomplished in 'B' regional office of oceans & fisheries for 5 years from 2014 to 2018. The contents to be analyzed are reprimand agencies, certificate kinds, officers ranks at that time, disciplinary level, violated acts, annual reprimand state, punishment rule and it process, and disciplinary reduction levels. From such valuations various problems, such as disciplinary level deviations among laws, insufficient punishments rules, disciplinary certificate deviation, insufficient reprimand reduction rules, and lack function of crew administrative disciplinary council, are identified. Finally, methods to alleviate the problems identified will be proposed. This study, for the first time analyses the actual administrative disciplinary cases for ship officers'certificates and proposes improvement plans for its incorporation in Korea, This analysis will be useful in the examination of the study for the ship officers and making a plan for them.

Purpose - This research aims to examine collaboration from a disciplinary perspective in Korea. There are needs to explore to what extent researchers collaborate by discipline and across discipline along with the impact of collaboration. Design/methodology/approach - In order to investigate collaboration with respect to entire discipline areas and author-declared discipline information we analyzed a national researcher information database (Korean Researcher Information) with a citation index database (Korean Citation Index) covering the entire range of discipline. This study analyzed the data sets for 10 years (2004-2013) including a total of 8 categories and 119 sub-categories of disciplines, 109,551 researchers, 650,263 articles, and 1,170,039 citations in Korea. Findings - The results demonstrate that there are different intensities of collaboration from heavy to minimal across disciplines. In examining collaboration in terms of author and discipline levels, the results show that collaboration in author level rises, then inter-disciplinary collaboration increases accordingly, in most of the 119 discipline sub-categories. A number of disciplines, however, tended to collaborate more intensely within their own rather than with other disciplines. Moreover, the impact of collaboration tended to change over time depending on the types of collaboration. Specifically, inter-disciplinary collaboration was likely to have more immediate impact as pioneer research, especially among more than three disciplines, whereas the impact of intra-disciplinary collaboration is higher as time passes. Originality/value - In this research, a disciplinary investigation on collaboration is conducted for the entire range of disciplines in Korea. Through analyzing distinctive author-declared discipline information from the KRI, this research examines the intensities of collaboration across disciplines, collaboration in author level, and the impact of collaboration.

The paper describes the development of a decomposition based multidisciplinary design optimization (MDO) method that coordinates each of disciplinary subspace optimization (DSO). A multidisciplinary design system considered in the present study is decomposed into a number of subspaces based on their own design objective and constraints associated with engineering discipline. The coupled relations among subspaces are identified by interdisciplinary design variables. Each of subsystem level optimization, that is DSO would be performed in parallel, and the system level coordination is determined by the first order optimal sensitivities of subspace objective functions with respect to interdisciplinary design variables. The central of the present work resides on the formulation of system level coordination strategy and its capability in decomposition based MDO. A fluid-structure coupled design problem is explored as a test-bed to support the proposed MDO method.

Ship design process requires lots of complicated analyses for determining a large number of design variables. Due to its complexity, the process is divided into several tractable designs or analysis problems. The interdependent relationship requires repetitive works. This paper employs collaborative optimization (CO), one of the multidisciplinary design optimization (MDO) techniques, for treating such complex relationship. CO guarantees disciplinary autonomy while maintaining interdisciplinary compatibility due to its bi-level optimization structure. However, the considerably increased computational time and the slow convergence have been reported as its drawbacks. This paper proposes the use of an approximation model in place of the disciplinary optimization in the system-level optimization. Neural network classification is employed as a classifier to determine whether a design point is feasible or not. Kriging is also combined with the classification to make up for the weakness that the classification cannot estimate the degree of infeasibility. For the purpose of enhancing the accuracy of a predicted optimum and reducing the required number of disciplinary optimizations, an approximation management framework is also employed in the system-level optimization.

This study describes an approach for comparative bibliometric analysis of scientific publications related to (i) individual or several departments comprising a university, and (ii) broader integrated subject areas using multiple disciplinary schemes. It uses a custom dataset of scientific publications (ca. 15,000 articles and reviews, published during 2009-2013, and recorded in the Web of Science Core Collections) with author affiliations to the research departments, dedicated to science, technology, engineering, mathematics, and medicine (STEMM), of a comprehensive university. The dataset was subjected, at first, to the department level and discipline level analyses using the newly available KAKEN-L3 classification (based on MEXT/JSPS Grants-in-Aid system), hierarchical clustering, correspondence analysis to decipher the major departmental and disciplinary clusters, and visualization of the department-discipline relationships using two-dimensional stacked bar diagrams. The next step involved the creation of subsets covering integrated subject areas and a comparative analysis of departmental contributions to a specific area (medical, health and life science) using several disciplinary schemes: Essential Science Indicators (ESI) 22 research fields, SCOPUS 27 subject areas, OECD Frascati 38 subordinate research fields, and KAKEN-L3 66 subject categories. To illustrate the effective use of the science mapping techniques, the same subset for medical, health and life science area was subjected to network analyses for co-occurrences of keywords, bibliographic coupling of the publication sources, and co-citation of sources in the reference lists. The science mapping approach demonstrates the ways to extract information on the prolific research themes, the most frequently used journals for publishing research findings, and the knowledge base underlying the research activities covered by the publications concerned.

The purpose of this study is to find the difference between the parents generation and that of the children in the disciplinary methods by means of parental social population variation. With these purpose in mind, the problems have been suggested like following: 1) what are the general differences of between the two generations of parents and children in disciplinary method? 2)What are the general differences of the views between those two generations according to sex? 3) What are the general differences between the parents generation and the child generation according to age? 4) What are the general differences between the parents generation and the child generation according to education level? 5) What are the general differences between the parents generation and the child generation according to income level? In order to solve these problems, questionnaries were distributed on this appendix 374parents (father: 177, mother: 197) who have the children. Questionnaires were compose on "Parents Inventory" of Radke were employs, classfied five measures. To test and verifying the above hypothes, the following five measures. were used. 1) Philosophy of authority (authoritarian vs. democratic) 2) Parental restrition (strict and stubbon vs. democratic) 3) Severity of punishment (severity vs. mildness) 4) Parent-child rapport 9desirable vs. undesirable) 5) Relative responsibility of father and mothehr towards child disciplinary (equal vs. differ) The result of this study is like follows: 1) In general comparison of two generations, tends to be more democratic in the philosophy of authority, more relaxed and easygoing in the parental restroction, more severe in the severity of punishment, and good rapport in the parent-child rapport than grandparents generation and the responsibility of father don't change but that of mother tends to augment in child disciplinary 2) In comparison of two generation according to sex, the mother showed more democratic in the philosophy of authority and closely perceive her parents in the parent-child rapport as compared with the father. 3) In comparison of two generation according to age, the younger parents showed more relaxed attitudes towards the child disciplinary, the perception better relations of their parents in the parent-child rapport. 4) In the comparison of two generations according to education level the more educated parents showed the more relaxed and easygoing attitude towards in the parental restriction. 5) In comparison of two generation according to income, as the parents of large income generally (not always) showed easygoing than their previous generation in the parental restriction, and they perceive that they have a good one in parent-child rapport. This study caused by the some difficult problem required futher investigation on the result of two generations the problems happened in the inner unitary of items. And, it proposed some problems which constitutes the problems of the proper interpretation of the results between two generations brought about discordance of items between tow generations

Large-scale Multi-disciplinary Systems(LMS) such as transportation, aerospace, defense etc. are complex systems in which there are many subsystems, interfaces, functions and demanding performance requirements. Because many contractors participate in the development, it is necessary to apply methods of sharing common objectives and communicating design status effectively among all of the stakeholders. The processes and methods of systems engineering which includes system requirement analysis; functional analysis; architecting; system analysis; interface control; and system specification development provide a success-oriented disciplined approach to the project. This paper shows not only the methodology and the results of model-based systems engineering to Automated Guided Transit(AGT) system as one of LMS systems, but also propose the extension of the model-based tool to help manage a project by linking WBS (Work Breakdown Structure), work organization, and PBS (Product Breakdown Structure). In performing the model-based functional analysis, the focus was on the operation concept of an example rail system at the top-level and the propulsion/braking function, a key function of the modern automated rail system. The model-based behavior analysis approach that applies a discrete-event simulation method facilitates the system functional definition and the test and verification activities. The first application of computer-aided tool, RDD-100, in the railway industry demonstrates the capability to model product design knowledge and decisions concerning key issues such as the rationale for architecting the top-level system. The model-based product design knowledge will be essential in integrating the follow-on life-cycle phase activities. production through operation and support, over the life of the AGT system. Additionally, when a new generation train system is required, the reuse of the model-based database can increase the system design productivity and effectiveness significantly.
