The present study examined the relationships among maternal attachment, self-concept, peer relationship, and school adjustment. The subjects were 293 Korean-Chinese elementary school students living in Yanji and Shenyang, China. The Inventory of Parent and Peer Attachment (Armsden & Greenberg, 1987), Social Competence Inventory(Doh & Falbo, 1999), and Self-Perception Profile for Adolesents(Harter, 1988) were used to measure the subjects' maternal attachment, and peer relationship, school adjustment, and self-concept, respectively. When structural equation modeling was applied, the results supported not only the model that maternal attachment and self-concept exert an influence on peer relationship, but also the model that they exert an influence on school adjustment. The results of this study suggest that the secure maternal attachment of Korean-Chinese works as an important mechanism that explains their peer relationship and adjustment at elementary school.

The learning, which is a view extended from and replaces the concept of continuous improvement, has become the very core concept in Malcolm Baldrige National Quality Award. The most potent one among 11 core values in MBNQA Model is 'organizational and personal learning'. Learning also plays a critical role to get the good scores for 6 categories except results category among 7 categories of MBNQA Model. But the concept of learning often has been overlooked by the people who are interested in the MB award or TQM. This paper reviews and analyzes the concept of learning in the MB criteria since it first appears in 1993 to enlighten the importance of learning.

There are various studies to provide useful information for users on huge data of web-sites. Web usage mining among them is a method to extract meaningful patterns based on web users' log data. Most of existing patterns of web usage mining, however, had not considered users' diverse inclination but created general models. Web users' keywords can have various meaning upon their tendency and background knowledge. This study is for generating Multi Concept Keyword Model (MCK-Model) by analyzing web usage information on users' keywords of interest. MCK-Model can supply web page network for various inclination based on users' keywords of interest. Also, MCK-Model can be used to recommend the most proper web pages and it has been confirmed that the suggested method is useful enough.

The new concept of dry area formation based on Poisson distribution of active nucleation sites and the concept of the critical active site density is presented. A simple statistical model is developed to predict the change of slope of the boiling curve up to critical heat flux (CHF) quantitatively. The predictions by the present model are in good agreement with the experimental data. Also it turns out that the present model well explains the mechanism on how the surface wettability influences CHF.

The purpose of this study is to improve the accuracy of service satisfaction by utilizing KSC (Kano, Score Model, Concept Position) analysis methods in order to present various fitness center service models for healthy new silver generation centered on P fitness center which runs six branches in Busan. Double Diamond-based methods led to a case study focused on the P fitness center's Yeon-san branch which well leading in a wide variety of leisure infrastructures for the senior citizens. Throughout this study, based on the insights extracted from the customers were culminating in nine service design models from the perspective of administrators and trainers. The final derived nine models have been evaluated by Kano's satisfaction evaluation, Concept score, and Concept position evaluation. All of the nine models results indicated as valid except for models 3 and 6. Finally, an implementation roadmap was proposed by dividing it into investment cost and effectiveness.

The purpose of this study is to evaluate the concept of the Business Art and the validity of the Business Art making process model, as well as to confirm the creative value of art in the business environment. The research data were collected using in-depth interviews and the collected data were analyzed by applying the grounded theory. As a result of the study, various experts in the fields of business and arts evaluated the concept of the Business Art and contents of the Business Art process model as generally valid, considering that they were actually applicable in light of their own experiences. This study establishes a new theory by verifying the transferability of academic research on the new concept of the Business Art, and presents a new viewpoint different from the existing one in the relationship between business and art. Also, the implication of this study lies in that it provided the basis for establishing the method and system that apply the concept of the Business Art and its process to business in the future.

Construction industry faces a lot of inherent uncertainties and issues and the construction phase of nuclear power project is not free from this risk. This paper investigates promising methodologies to be used on nuclear power plant (NPP) construction schedule delay risk assessment by using entry level systems engineering approach. This study contains how the initial concept for the risk assessment methodology has been developed. In this point of view, this work structured on three main phases: needs analysis (NA), concept exploration (CE), and concept definition (CD) through systems engineering (SE) approach. Traditionally, the SE process is applied to technical development programs but this study opens up a new avenue that SE can also be successfully applied to the development and optimization of the risk assessment model. This study provides a rational and systematic process for developing and selecting the best risk assessment model. This paper selects analytic hierarchy process (AHP) method to assess NPP construction schedule delay risk for international project. As conclusion, the proposed concept and selected method can discriminate successfully and clearly among schedule delay risk assessment methods.

This study uncovered ambiguity and inconsistency of the semantic relationships of the existing thesaurus by analyzing the concept relationships of AGROVOC and proposed the concept relationships of ontology in partially overcoming these limitations. By the results of analyzing the concept relationships, the study proposed conceptual model as most important part of conecept relationships of ontology and semantically developed concept relationship types. These relationships partially can perform inferences and must be useful for information knowledge system based on more exact semantic relationships. Also the study found out new relationship types and they will be useful for extension of the concept relationships of existing thesaurus. And these relationship types showed that they were useful for the existing thesaurus as Legal Thesaurus.

In the irrigation facilities, the irrigation system is connected systematically, and thus, it agrees to the object-oriented concept. Since it is necessary to go through comparative evaluations and to devise several alternatives plans in designing the irrigation system, it will be very efficient to use the objects that contain the design data. In this study, the object-oriented methodology has been proposed to define the objects, which will be used in the design system of irrigation facility. Furthermore, as for the essential elements of the objects, concept of element objects is formulated. By employing this concept, appropriate element objects have been derided for the irrigation facility. Necessary data model for realization of the objects is examined and selected. And then, required elements for applying the selected data model to the irrigation facility will be proposed

Chaotic dynamics have been studied by many researchers in the fields of biology, physics, and engineering. Interest in chaos is also expanding to the social sciences such as politics, economics, and others, including the prediction of societal events. The concept of leisure has developed from a passive concept correlated with relaxation, entertainment, and ideology formation into a positive concept that assumes a more active role. As information and communications technology develops, digital leisure activity is expected to continue spreading. This expansion of digital leisure function correctly, as well as. Traditional leisure activity functions correctly more, whereas digital leisure activity is predicted to function incorrectly more often. In this paper, we propose a mathematical addiction model of digital leisure that deals with its dysfunctions such as addiction to digital leisure, including computer games, internet search, internet chatting, and social media. Herein, to solve addiction to digital leisure, we propose a model derived from a nicotine addiction.
