In this paper, a practical estimation method is developed for the lot travel distance in order to evaluate semiconductor unified fabrication layouts using the absorbing Markov chain. The lot travel distance is defined as the total distance that a lot travels from the first process to the last process; it can be used to investigate whether a fabrication layout design is reasonable. Furthermore, unified fabrication has not yet been introduced in the literature; it is a fabrication method that uses only one type of automated material handling system (AMHS). When designing semiconductor fabrication layouts, every aspect of all alternatives should be investigated meticulously. The widely known and accepted methods, such as sophisticated simulations and mathematical modeling with high accuracy, require an extensive time period to build the model. However, in the early stages of the layout design, simple and insightful methods are required in order to investigate the numerous alternatives during a short time period. This paper presents a simple estimation method for the travel distance of a lot during its lifetime in a fabrication.

This study is aim to develop serial-processes of various alternatives for improvingproduction ability and designing optimal layout including machine layout and resonable material handling system based on the 4M (Man, Machine, Method, Material) analysis and to verify the reliable application to the actual field. In this paper, as a case study, we demonstrate an applied example of the practical technology of intelligent digital factory in a real vehicle shaft manufacturing line. By utilizing the MI-NPS Digital Factory Methodology, we can increase production ability and decrease waste of material handling as a result of solving the existing problems. Also, 3D simulation is performed to confirm the validity of elicited results. Collectively, we effectively develop various alternatives for an optimal layout and reasonable material handling system. Furthermore, we expect to build up the efficient production system dealing with changes in 4M and production schedule.

This research considers a development of framework of service characteristics design for airlines. The design framework utilizes QFD(Quality Function Deployment) and Fuzzy Theory to reflect customer’s angle in service design and to absorb respondents’ vagueness and ambiguousness in linguistic expression respectively. ABC analysis is also adopted to set up the goals of service characteristics design. Two cases for Korean and Asiana Airlines are studied to apply the proposed framework. The results show that both companies maintain high competence for most service quality characteristics except reservation and ticketing services which are major concerns of customers. Especially, Asiana Airlines shows lower competence for those services and minor 6 services than Korean Airline.

SC marketing is a new type of e-Commerce which generates profit to all SC companies, SC retailers, and customer. This paper classified SC products provided by SC retailers which perform SC marketing into 5 patterns made by 2 axis of differentiated high/general quality level and tengible/untengible products. Increasing productivity strategies appropriate for each patterns of SC retailers have been studied and the results are as follows. First, high quality-service goods which is provided by SC retailer are available for off season marketing strategy and useful in high quality facility and equipment business. High quality-service goods can maintain the marginal profit and loyal customers during holidays, weekdays or off season. Second, high quality-tangible products which is provided by SC retailer are available for the strategy to enhance the image during market entry of new products and useful to maintain regular customers. Third, ordinary quality-service goods which is provided by SC retailer enable to save short-term mass customers, and gain profits with using cross-selling, which means to induce additional selling. Forth, ordinary quality-tangible products which is provided by SC retailer are useful to save short-term mass customer and to improve turnover ratio while using small profit and quick return strategy. Fifth, excessive inventory goods(products) which is provided by SC retailer are useful to zeroise long-term harmful inventory. In this case, deep discount around 60∼80% is very effective strategy.

The purpose of this study is to prepare an opportunity of reinterpretation on the QWL standard followed by the periodic trend. In order to search for the introduction and promotion strategies of the Employee Assistance Program which is one of the corporate welfare systems recently being highlighted, certain type of implications have been attempted to be gained as a problem awareness on the practical level through research to begin with. As a result of analysis, while the validity of a model set up based on the relationship between employer characteristic, QWL and employee assistance program has been accepted, it has shown the fact that an examination on the research model reflecting various relationships between the variables is a task that much be continued. Especially, the search of employer characteristics called employer cooperation and social responsibility on the employee assistance program at current point in time when the establishment of Industrial Safety Act and support system on job stress management and mental health promotion issue of the laborers are being prepared is expected to become a useful research project. The reason is because the employer is a variable having greatest influence in the organization’s performance so that the role of an employee, especially the support activity, is being emphasized as to which direction the relationship between employees and labor union will progress by its strategic decision. As a result of this study, the satisfaction assistance program on the employees by the introduction of employee assistance program and promotion of operation at current point in time has mediating effect between employer characteristics and QWL while having positive effect in terms of QWL improvement.

In this paper, we measure the degree of ICT industry convergence by industry and analyze its effects on industrial production and employment respectively. We measured the ICT industry convergence as ICT intermediate input ratio to gross output on the constant price basis using BOK’s input-output tables. With the panel data consisting of 4 years(year 1995, 2000, 2005 and 2010) and 64 industrial sector, economic impacts were analyzed using the fixed effect and AB[Arellano and Bond(1991)] estimation methods. According to the analysis results, firstly, it is shown that ICT industry convergence has increased to a great extent since 1995. The level and increase of ICT industry convergence depend on those of several industries such as electrical & electronic, precision instrument and broadcasting & communication service industries. Secondly, the level and increase of ICT industry convergence have been affected by those of ICT manufacturing convergence. Thirdly, while ICT industry convergence affected industrial production positively, we did not find that it made negative effect on industrial employment, differently from general expectation. Fourthly, while ICT manufacturing convergence made positive effect on industrial production, it did not affect industrial employment negatively. Lastly, we find that ICT service convergence has a possibility to make positive effect on industrial production and also affected industrial employment positively.

Busan port, the 5th in the world in container trade volume, is facing a serious problem of decreasing trading volume due to the global financial crisis and unstable stevedore market situations. In this regard, this study focuses on the improvement of competitiveness of Busan port from the perspective of stevedore market stabilization, which has been a major issue in previous researches. Using AHP(Analytic Hierarchy Process), and based upon the survey of experts including container terminal operators and ship owners, the main factors for market stabilization are extracted and weighed according to their importance. As a result of the analysis, the establishment of port development plan balancing supply and demand is the most important factor among others, which implies that the plan in the long run should be based on the analysis of current birth operating situations and global trade volume trends. Secondly, terminal operators put significance on Busan North Port restructuring, while ship owners on establishment of co-operational firms. Thirdly, to attain stevedore market stabilization, fair competition regulations and adjustment of port operating charges are important in the short term, and more flexible port development plan considering both Busan North port restructuring and supply-demand balance should also be considered in the mid and long term.

In this paper, we analysed the absolute and conditional convergency hypothesis and the determinants of productivity in manufacturing industries from 2000 to 2009 with seoul metropolitan regions(Seoul, Gyeonggi, Incheon) by using panel analysis. In terms of convergency hypothesis test, all of the seoul metropolitan regions reject the null hypothesis(H0) except Incheon implying the labor productivity of the seoul metropolitan regions converged to the steady state equilibrium except Incheon in terms of conditional convergency. In addition, the speed of absolute convergency in Seoul show that Jungnang and Dongjak gu are the fastest regions in Seoul, but Gwanak and Nowon gu are the fastest regions in terms of conditional convergency. Jongno gu is the slowest region for the both convergency hypothesis. For the Gyeonggi province's 31 regions, it is difficult to estimate the speed of convergency due to varying of regional characteristics. For the Incheon, each region has the different speed of convergency showing that Ganghwa is 1.72% and Junggu is 1.52%. In addition, the results of the determinants of the labor productivity in manufacturing industry show that human capital doesn't affect to the value-added per capita in Seoul and Gyeonggi province but affect to Incheon. In addition, manufacturing location and government expenditure per capita coefficient affect to the value- added per capita in Seoul metropolitan regions significantly. Hence, for the total factor productivity, the government has to revise the balanced regional development policy to develop regional manufacturing industries with R&D activities.

This paper investigates interindustry knowledge spillovers using input-output (IO) data and patent information, since spillovers can arise from different types of sources and linkages. Economic transactions of intermediate goods are used to track embodied knowledge flows with the data derived from Korean IO tables. In terms of disembodied knowledge flows, a technology proximity matrix is constructed using patent information. The empirical results show that patterns of interdependences among industries are different and this implies that policymakers should take into account the interdependences between industries even when planning industry-specific policies. Moreover, excessive concentration of R&D investment needs to be improved.

Because of the rapidly changing environment and increased uncertainty, businesses need to respond quickly and accurately in a facing situation. Recently, many organization and companies introduce ‘smart-work’ in order to provide a flexible working environment. smart-work makes work to be continued without restriction of time and place to perform real-time enterprise. The purpose of this study is to confirm and verify factors which influence on smart phone mobile office accommodate decision process through finding characteristic of smart phone and mobile office, user’s personal characteristic and acceptance factor to smart phone users who have used mobile office. Theoretical model is presented through previous study and practical verification is conducted through survey. Independent variables are characteristic of smart phone(diversity, security), characteristic of mobile office(instant connectivity, riskiness, complexity), user’s personal characteristic(user’s familiarity, user’s innovation) and parameters are perceived usefulness, perceived ease of use and dependent variable is use intention. Survey is conducted to verify the relationship among these variables and examined by the structural equation modeling. The results of this study are as follows. First, the concern about security of the characteristics of smart phone gives a negative influence on the intension to use. Second, it is reconfirmed relationship between perceived ease of use and the perceived usefulness which are the key variables effecting on the intention to use in TAM. Lastly, difference of the intention to use between the genders is confirmed.

This paper empirically examines the effect of corporate governance on operating performance for Korean listed companies over the period 2003-2012. It employs the 2 stage least square procedure to control for potential endogeneity of corporate governance variables. This paper uses as a proxy for corporate governance various evaluation scores which the Korea Corporate Governance Services partly announces recently. Our empirical results show that corporate governance should be positively associated with firm profitability for which return on assets is used as a proxy variable. The corporate governance scores are found to be endogenous and thus simple OLS estimation of the model by ignoring the endogeneity of the variable can produce biased results.
