The interest in economics and efficiency of IT investment is growing as the amount of overall governmental IT investment steadily increase. Accordingly, there is a strong need to determine whether the expenditure incurs effectively for IT investment and to accurately analyze the economics of IT investment, In this perspective, this study discusses the prior researches on concepts regarding the analysis of IT investment management framework as proposed from academic and professional perspectives in advanced countries' government sectors. Thereafter, an adoption of IT investment management (ITIM) framework has been considered so as to enhance the performance of ICT initiative projects in the public sector. In the suggested IT investment management framework, we suggest economics and efficiency of public IT investment should be improved by integrating ICT project selection and control as well as evaluation stage into single governance framework.

Gas-assisted injection molding is an innovative low-pressure injection molding technique that can provide numerous benefits such as reduced part warpage, excellent surface quality without sink marks, low injection pressure, and greater design flexibility. However, the adoption of gas-assisted injection molding may cause unexpected defects if the gas channel design is not conducted properly. The objective of this paper is to broaden the understanding of gas-assisted injection molding by summarizing the design procedures and experimental results of the gas-assisted injection molding of a 17" flat monitor front cover. The gas channels were designed by using Moldflow(MF/GAS) simulations and a 450 ton injection molding machine with a 5 stage pressure control gas kit was used in the experiments.

Public sectors around the world utilize social media tools and technologies in their daily activities for a variety of purposes, including disseminating useful information, fostering mass collaboration, and enforcing laws and regulations. A number of social media-based government stage models have emerged to document this use. In this chapter, we conducted a qualitative meta-synthesis of four social media-based government models. These models include 1) the open government maturity model, 2) the social media utilization model, 3) the adoption process for social media, and 4) the social media-based engagement model. The concepts, metaphors, and themes contained in these developmental models are extracted through a series of in-depth semantic analyses of descriptions, resulting in a common frame of reference.

This study examines which factors are urging Korean companies to participate in e-marketplaces. By adding interorganizational factors, we extended an innovation-theory-based research model that is often applied to study the information technology adoption. 71 questionnaires from 720 Korean manufacturing companies were collected. Independent variables of the research were environmental, organizational, innovation, and interorganizational characteristics. We found that the environmental characteristics, innovation characteristics, and interorganizational characteristics have insignificant effect on the participation of domestic companies in e-marketplaces whereas the organizational characteristics have significant relationship with the participation in e-marketplaces. The result implies that many Korean companies take wait-and-see strategy in the forming stage of e-marketplaces, However, IT infrastructure and the support of top management for IT play very important role in adopting e-marketplaces.

The Korean nuclear industry acquired technology for each construction stage including engineering, procurement, construction and commissioning from advanced nuclear countries. While the levels of technology and quality have greatly improved, the same cannot be said for the level of project management. In particular, the level of project performance measurement and forecasting project risk still remain at the single project management level. Thus, this paper reviewed the concept of the EVMS method and requirement for the system. The adoption of the EVMS, an advanced project management method, can enable efficient management of project risks and promote an adequate environment for project implementation.

Purpose - This research aims to examine the effect of e-business adoption on firm's growth and profitability in the distribution industry. The value added from the distribution industry acts as the cost of other industries. As the distribution industry develops, its stage becomes shorter and the distribution margin becomes smaller. Therefore, e-business is expected to have a different effect on the distribution industry than other industries. Research design, data and methodology - The previous research generally used e-business adoption as an independent variable and firm's performance as a dependent variable. This study elaborated the model using a dynamic panel model that includes the performance variable of the previous year as an independent variable. By employing system GMM (Generalized Method of Moments), the endogeneity problem in the dynamic panel model can be solved. For the analysis, I extracted the distribution companies as the raw data in the National Statistical Office's Business Activity Survey over the period 2006 to 2012. Results - The growth rate of firms adopting e-business was 0.299%p higher than that of the non-adopter. However, only ERP (Enterprise Resource Planning), KMS (Knowledge Management System) and SCM (Supply Chain Management) contributed positively to the growth rate. In the case of profitability, it was 0.04%p higher than the distribution companies that did not adopt e-business. ERP and LMS (Learning Management System) improve profitability, while SCM reduces profitability. Consequently, while ERP improves both growth and profitability, SCM improves growth but reduces profitability. In addition, KMS improves firm's growth only, and LMS does only profitability, showing that each e-business has a differentiated effect. Conclusions - Since the distribution industry has different characteristics from manufacturing and other service industries, the introduction of e-business may not guarantee the growth and profitability of distribution companies. Careful introduction considering the characteristics of the distribution industry is required. In particular, it is necessary to select an e-business meeting the characteristics and needs of a distribution company, and thereafter, it is required for the company's own efforts to internalize it within the system.

Sustainable design is getting to be controversial issue in all industries over the world particularly, in architecture as the amount of energy usage in architecture occupies 40%. Therefore, it is essential to make the standard for the sustainable design. In order to construct the sustainable design, firstly it should be considered that sustainable design elements based on natural resources to increase building energy efficiency is established and classified. The method of sustainable design divides into passive design and active design. Passive design method should be examined with active one simultaneously for more efficient usage of energy. Next, the study is followed how the sustainable design elements is adopted in buildings through the comparison of cases study of domestic and oversea. The result of case study shows similar adoption of sustainable design elements between oversea and domestic. However, the difference is shown in the building orientation and shape and the window size and position in Solar energy as well as high performance structure in Heat energy. These elements are the most significant elements in order to reduce energy load. In oversea, sustainable design is generated by architects, a client, and consultants based on the close cooperation in the beginning of early design phase before deciding building shape and envelope while in the domestic field adoption for sustainable design is conducted after deciding building shape and material. In order to design sustainable architecture more study is necessary in early stage for Zero Carbon and reducing building energy load through relation with specialists, a client and architects.
