3D printing is attracting attention from all industries as it enables the development of personalized product design to meet consumer needs by establishing a mutual connection system between production, management and consumers. However, there are still limitations to applying them as apparel materials, and research on the recognition of 3D printing or the preference for fashion products is needed to actually commercialize 3D printing in the fashion industry. In this study on the development of various product designs using 3D printing technology in the fashion industry, an analysis of 255 questionnaires was conducted to determine the preferences and purchase intention trends of fashion product design using 3D printing for college students. Data analysis was performed with IBM SPSS Statistics (V.24). 'Fashion sensitive pursuit', 'Individuality & brand pursuit' and 'Functional convenience' was interested in fashion accessories using 3D printing technology and customized fashion apparel products using 3D printing. 'Functional Convenience-oriented' and 'Practical Purchasing-oriented' type showed that the functionality and durability of products made using 3D printing technology were important. And 'Individuality pursuit' type indicated that design and applied materials were important when producing products using 3D printing technology.

Marine clays are soft soil deposits having complicated mineralogy and formation characteristics. Thus, characterization of its geotechnical behavior has been a main issue for geotechnical engineers. Nowadays, the importance and applications of geophysical exploration on marine clays are increasing significantly according to the accuracy, efficiency, and reliability of geophysical survey technology. For marine clays, seismic survey is effective for density and elasticity characterization, while electro-magnetic wave provides the information about the fluid conductivity phenomena inside soil. For practical applications, elastic wave technology can evaluate the consolidation state of natural marine clay layers and estimate important geotechnical engineering parameters of artificially reclaimed marine deposits. Electrical resistivity can provide geophysical characteristics such as particle cementation, pore geometry shape, and pore material phase condition. Furthermore, nondestructive geophysical monitoring is applicable for risk management and efficiency enhancement during natural methane gas extraction from gas hydrate-bearing sediments.

The purpose of this study is to find out the essence and the meaning of conventional filial piety and its education to be a help to build up a moral society. Consequently the main point of this study is grafting our filial piety to industrial society and reviewing our conventional filial piety at the present time and what is the role of education. The traditional thought of our people is based on the filial piety and it is based on the basic love in humanity that is is rooted in the principle of benevolence. We should realize the most important practical principles of reverent affection. Our traditional filial piety has been handed down along with long history. though it has been a little chaned to meet the needs of the times. We should not forget that the fundamental thought of filial piety has never changed. The education for filial piety in modern society should be taken charge of by family society and school and be helped each other So the filial piety thought as tradition l ethics has to be adjusted to the modern sense. We should make a considerable point of the filial piety education for value which will bring about the recovery of humanity.

This research examines the importance of self-leadership and manners in enhancing the adjustment to school life in adolescents. The findings are used as part of a practical strategy to develop strong high school cultures. The data were obtained by administering a self-reported questionnaire to high students adolescents residing in Seoul and Gyeonggi. A total of 316 questionnaires were used as the final data for this study. Statistical analyses were carried out using SPSS/PC. The main results of the study are as follows: First, the adolescent's self-leadership greatly influenced the student's manners. Second, the relationship between self-leadership, manners and the adjustment to school life showed a significantly positive correlation. Third, a stepwise regression analysis showed that self-leadership competency and implementation of manners made a comparatively high contribution to the adolescents' adjustment to school life. Therefore, the degree of the student's self-leadership and use of manners in order to maintain harmonious relationships with others leads to a healthy and happy scholastic life for the student.

In Hwaseong, South Korea, it is necessary to vitalize local festival by attracting local residents and tourists since 'Hwaseong Songsan Grape Festival' should be in the direction to help the influx of tourists and cultural development for the local residents. It has been known that the quality and readiness of festival affects visitor satisfaction and actual visit. However, there have been only a few studies to examine the effect of local festival on post-behavior. Hence, this study, focusing on 'Hwaseong Songsan Grape Festival'which is a representative cultural tourism festival in the region of Hwaseong, South Korea, aims to understand the visitor's post-behavior intention in terms of revisit intention and recommendation intention. The results suggest that the impact of experiential, purchase visit motivation on post-behavior were smaller than deviant, social, interest, and cultural visit motivation. It also showed that visitor satisfaction leads to revisit intention and at the same time recommendation intention. Based on the result, we suggest practical implication for the success of local festival including 'Hwaseong Songsan Grape Festival'.

For moving cargo between the North Pacific region and Northern European ports, the Northern Sea Route, along Russia's coastline, is 35-60% shorter than the traditionally used routes through the Suez and Panama Canals. In addition to its shorter distance, there exists and extensive ports and shipping infrastructure, and the potential for developing new markets in Russia and other northern countries including Korea and Japan. These incentives attracted considerable attention from the international shipping and shipbuilding industries and have formed a cooperative international research program, called as the International Northern Sea Route Programme (INSROP). This paper is a general compilation of the historical usage, recent trade developments, the physical environment, and the practical considerations that may shape future operational mode of shipping in the NSR based on results from INSROP reports. This study focuses mainly on an operation of commercial icebreaking vessels that may be utilized along the NSR.

Among the state-space description of discrete vent systems, the max-plus algebra is known as one of the effective approach. This paper proposes a model predictive control (MPC) design method based on the max-plus algebra. Several studies related to these topics have been done so far under the constraints that system parameters are constant. However, in practical systems such as production systems, it is common and sometimes inevitable that system parameters vary by each event. Therefore, it is of worth to design a new MPC controller taking account of adjustable system parameters. In this paper, we formulate system parameters as adjustable ones, and they are solved by a linear programing method. Since MPC determines optimal control input considering future reference signals, the controller can be more robust and the operation cost can be reduced. Finally, the proposed method is applied to a production system with three machines, and the effectiveness of the proposed method is verified through a numerical simulation.

Multiperiod portfolio selection problem attracts more and more attentions because it is in accordance with the practical investment decision-making problem. However, the existing literature on this field is almost undertaken by regarding security returns as random variables in the framework of probability theory. Different from these works, we assume that security returns are uncertain variables which may be given by the experts, and take absolute deviation as a risk measure in the framework of uncertainty theory. In this paper, a new multiperiod mean absolute deviation uncertain portfolio selection models is presented by taking transaction costs, borrowing constraints and threshold constraints into account, which an optimal investment policy can be generated to help investors not only achieve an optimal return, but also have a good risk control. Threshold constraints limit the amount of capital to be invested in each stock and prevent very small investments in any stock. Based on uncertain theories, the model is converted to a dynamic optimization problem. Because of the transaction costs, the model is a dynamic optimization problem with path dependence. To solve the new model in general cases, the forward dynamic programming method is presented. In addition, a numerical example is also presented to illustrate the modeling idea and the effectiveness of the designed algorithm.

The rise of crowdsourcing and web 2.0 opens plenty of opportunities for companies who want to exploit external sources of ideas for internal innovation. Utilization of crowdsourcing for product design and development has been attracting the attention of both enterprises and researchers. Many cases of implementation of crowdsourcing for product design and development such as: Threadless, FIAT Mio, Lego online Factory, etc., have made crowdsourcing a promising alternative source of innovative power. Although crowdsourcing gained access due to improved Internet access and web 2.0, it is little understood how the crowd, with respect to participation, behaves for any crowdsourcing project. To investigate this, we conducted an experiment on a real crowd of engineering related individuals to figure out the crowd participation pattern for various product design and development phases of a new product development project. The experiment results give a quantitative view of the participation of the crowd (i.e., crowd participation pattern) in various phases of a product design and development process that utilizes crowdsourcing, provide a practical guidance for companies to harness the power of the crowd sensibly, and provide experimental data for further research in this field.
