Although a commercialization of developed technology is an important factor for firm's competitiveness, the success rate in technology commercialization is significantly low. This fact raises a need of an analysis on factors affecting success in technology commercialization. Thus, in this study, in order to determine the success factors of technology commercialization, statistical analysis is done on 4 different elements of Korean automobile industry firms: managerial group attitude, market orientation, technology quality, and government support; and developed a causal-relationship model of the above elements and commercialization. In the developed model, two moderating variables, corporate ability and industry classification, are added to determine the level of correlations respect to two moderating variables. As a result of hypothesis tests, market orientation, managerial attitude as an antecedent variable; and government support, technology quality as an antecedent variable, both have significant correlation with technology commercialization. For moderating variables, a corporate ability has moderating effects on the connections of managerial attitude, market orientation and technology commercialization; but an industry classification has a moderating effect only on the link between technology quality and government support. The results of this research serve a contribution to the development of R&D efficiency improvement by providing government with direction in science & technology policy.

There are many different job skill evaluation scales, but the development of the job skill scale for the workers in the local child care centers has much to be improved. The purpose of this study is to develop and validate the job skill scales for the workers of local child care centers. It is also the purpose of this study to specify the scope of work for such workers and define the job skills to develop a tool to evaluate the job skills of them, eventually. As for the study method, the researcher conducted literature review and Delphi survey to extract the job skill factors. Then, after going through a discussion with an expert, the researcher developed the preliminary questions to verify the validity of the contents and the certification validity. For this, a survey was conducted with the workers in local child care centers across the country, and a total of 221 questionnaires have been used for analysis. With this, a total of five job skill factors for such workers were identified, based on which 20 questions were developed to constitute the scale. The sub-factors identified were student supervision, program planning, child education, administrative works, and link-up with the local community. The confidence level of the scale developed in this study was Cronbach ${\alpha}=.940$(N=221). With the scale of the job skills of the workers in local child care centers, it would be possible to develop various job skill programs. And, this would be able to be used for evaluating the job skill levels of not only the workers in the local child care centers but also other child-care service providers.

As the competition among the autonomous vehicle (AV, here after) developers are getting fierce, Korean government has been supporting developers by deregulating safety standards and providing financial subsidies. Recently, some OEMs announced their plans to market Lv3 and Lv4 automated driving systems. However, these market changes raised concern among public road management sectors for monitoring road conditions and alleviating hazardous conditions for AVs and human drivers. In this regards, the authors proposed a methodology for monitoring road infrastructure to identify hazardous factors for AVs and categorizing the hazards based on their level of impact. To evaluate the degrees of the harm on AVs, the authors suggested a methodology for managing road hazard factors based on vehicle performance features including vehicle body, sensors, and algorithms. Furthermore, they proposed a method providing AVs and road management authorities with potential risk information on road by delivering them on the monitoring map with node and link structure.

Building information modeling (BIM) can help to visualize and manage the building-related information at the object-based level, and it is possible to help link the tasks in the network of Hanok construction. While many studies have significant interest in using BIM for modern construction, there is only few studies to observe the use of BIM for traditional construction, commonly called Hanok construction in South Korea. Hence, the main goal of this study is to develop a system dynamic model for investigating how the BIM can be widely used for Hanok construction. To this end, this study identified the factors influencing the BIM uses for the Hanok construction, developed a causal loop diagram (CLD) to investigate the interrelationships among the factors, and provided a final model based on the mathematical definitions. Based on the scenario analysis, it is demonstrated that the support to building Hanok and education cost for BIM positively influence activating and using the BIM for the Hanok construction. Based on the dynamics of the factors identified in this study, it is important to consider expanding support for Hanok construction and education cost for BIM to successfully integrate and utilize BIM in the construction industry.

We all know that we can not keep a proper social life without language. Yet language is so much a part of our environment that we hardly realize it is there. The purpose of this study is to provide an understanding of the linguistical aspect of communication process in order to carry out a successful human relations in the operation of libraries. Human development rests upon man's capacity to digest large quantities of knowledge and it is language which allows facts to be communicated, stored, and disseminated. An attempt was made in this study to illustrate the elementary meaning-of-words aspect of communication. In order to share the most commonly agreed meanings in interpersonal communication, a careful study of semantic noises is important. In a constant struggle to meet client needs, staff and administrators, librarian must understand communication dialogues, their messages and be able to read all level of meanings. In order to perform a successful function of the librarian, to act as a link-man or communicator and to cope with its ever growing information, it is suggested that the deep understanding of the following linguistical aspect of communication elements is essential. 1. Characteristics of Language: (1) Words have different meanings to different people. (2) Words vary in the degree of abstraction. (3) Language is incomplete by its nature. (4) Language reflects not only the personality of the individual but also the culture of man's society. 2. Noises in transmitting meanings: (1) Mechanical or Technical noises. (2) Semantic Noises (3) Noises caused by the psychological factors a. attention b. perception, sensation, cognition and perceptual field. 3. Linguistic Stratum Languages differ considerably in vocabulary by the physical and cultural environment setting as well as situation of individual living. There are seven different language stratum which reflects different region, sex, age, profession, special social stratum, academic and tabooed words.

A planned access method on constantly-changing-community unit plan changes and develops based on the periodical situation and also plan theory. In this research, it is to present the link between the theory of complex city change and the plan factor of it, and to show how Korean residential complex plan has changed as time passed and how new concept of city plan came up and by applying new methods how can this affect our real world and the past plan. In the phase of analysis, it analyzed the flow of 'community unit plan' and its theory and investigated the factor of compositional space and built a analysis frame. The factors of community unit plan are space structure, size and shape of block, population, distribution of facilities and movement system. It chose the place that can represent the flow of community unit plan trand and that indicates the obvious development leading to Jamsil (1975), Gwa Chun (1980), Mok Dong (1983), Sang Ge (1985), Ilsan (1989), Dong tan (2001) and Eun Jung (2003) total of 7 places. And to compare a similar size of the city, it selected a small community unit. Based on the result of theoretical study and prior research, it can be said that the space composition style has change from a whole complete complex area to a linked-cross over community unit and the access of urban level was on set. Also, a pedestrian walking area was secured and the dense of building structure and pleasant environment wanting need was in balance. For facility plans, the usage of facility and functional change brought change of type, size and disposition. The walking area for pedestrian became a huge matter. Therefore, market, education, public facilities and green system collaborated to co-build a whole community unit and activated the walking environment. Also, public transportation, environment friendly city organization was built.

This paper deals with an automated computer-aided process planning and die design system with which designer can determine operation sequences even after only a little experience in process planning and die design of multi former-bolt products by multi-stage former working. The approach is based on knowledge-based rules, and a process knowledge base consisting of design rules is built. Knowledge fur the system is formulated from plasticity theories, empirical results and the empirical knowledge of field experts. Programs for the system have been written in AutoLISP for AutoCAD with a personal computer. An attempt is made to link programs incorporating a number of expert design rules with the process variables obtained by commercial FEM softwares, DEFORM and ANSYS, to form a useful package. The system is composed of four main modules. The process planning and die design module considers several factors, such as the complexities of preform geometry, punch and die profiles, specifications of available multi former, and the availability of standard parts. It can provide a flexible process based on either the reduction in the number of forming sequences by combining the possible two processes in sequence, or the reduction of deviation of the distribution and the level of the required forming loads by controlling the forming ratios. The system uses 2D geometry recognition and is integrated with the technology of process planning, die design, and CAE analysis. The standardization of die parts for multi former-bolt products requiring a cold forging process is described. The system developed makes it possible to design and manufacture multi former-bolt products more efficiently.

As maintaining customer long term relationship is critical factor for improving to firm value as well as customer lifetime value, the academicians and practitioners have paid attention to customer defection. It is said that service failures are key factors to customer defection or customer switching(Keaveney 1995 etc.). This study examines that the effect on customer defection of service failures is differential according to the various customer-firms relationship characteristics. We consider relationship duration, usage level, decision making influence, industry knowledge and switching cost as customer-firm relationship characteristics based on marketing literature. Predictions are developed and tested using Internet service provider(ISP) user survey data(n=212). Results show that the customer-firms relationship characteristics/above variables) play a moderating roles in the service failures and customer defection links.

In the satellite communications, the frequency sharing with other services is important because the service coverage is generally very wide and overlaps with those of other wireless services. This paper introduces a new technique to mitigate interference into the terrestrial stations from the Earth station in the same frequency band by means of band segmentations which are portions of the overall operation frequency band divided by frequency reuse factor. We consider a multi-beam satellite system, where frequency bands are reused in each satellite cell. The terrestrial stations use band segmentations of adjacent satellite cells, and this may decrease the interferences. By this way, the terrestrial and satellite systems can share the same frequency bands efficiently. The simulation is performed at frequency reuse factors, seven and three. The simulation results show that the proposed method can highly reduce the interference level to -168 dBW or -163 dBW depending on the considered frequency reuse factor from -117 dBW at the 90% link availability.
