In the past decade, considerable effort has been devoted unsuccessfully to the development of information technology (IT) evaluation frameworks in the information systems area. Based on the literature review in this area and the decision analysis field, two competing evaluation frameworks are developed in this study: the direct evaluation framework and the indirect evaluation framework. A case study on Firm K shows that the latter is more practically efficient and theoretically appropriate but requires the adequate training for practitioners in order not to get confused the weight of an evaluation variable with the product of this weight and the score of the variable. Another finding is that Weill's conversion effectiveness is neither possible nor necessary to measure in the process of evaluating an IT although it is in theory an important concept.

Early criticality prediction models that determine whether a design entity is fault-prone or not are becoming more and more important as software development projects are getting larger. Effective predictions can reduce the system development cost and improve software quality by identifying trouble-spots at early phases and proper allocation of effort and resources. Many prediction models have been proposed using statistical and machine learning methods. This paper builds a prediction model using Support Vector Machine(SVM) which is one of the most popular modern classification methods and compares its prediction performance with a well-known prediction model, BackPropagation neural network Model(BPM). SVM is known to generalize well even in high dimensional spaces under small training data conditions. In prediction performance evaluation experiments, dimensionality reduction techniques for data set are not used because the dimension of input data is too small. Experimental results show that the prediction performance of SVM model is slightly better than that of BPM and polynomial kernel function achieves better performance than other SVM kernel functions.

This study investigated various alternatives for childcare among dual-earner families and discussed implications for public policy development. Eight employed married women and two of their husbands were interviewed about work-family balance. All the interviewees complained that taking cue of the children in dual-earner families is a challenge. They resort to all available alternatives because public childcare support is insufficient and inadequate. There were five different types chilcare: extended family network, public and private institutions, paid help (nannies), rearranging work schedules, and training their children to take cue of themselves. However, all these alternatives entail various problems. More and better childcare facilities and programs should be built and after-school programs should be designed. On the other hand, parents should also make more effort to prioritize children's needs in finding a balance between work and family.

Spoken dialog system development includes many laborious and inefficient tasks. Since there are many components such as speech recognizer, language understanding, dialog management and knowledge management in a spoken dialog system, a developer should take an effort to edit corpus and train each model separately. To reduce a cost for editting corpus and training each models, we need more systematic and efficent working environment. For the working environment, we propose DialogStudio as an spoken dialog system workbench.

Systems engineering is an interdisciplinary approach encompassing the entire technical effort to evolve and verify an integrated and total Life cycle balanced set of system, people, and process solutions that satisfy customer needs. Systems engineering is the integrating mechanism across the technical efforts related to the development, manufacturing, verification, deployment, operations, support, disposal at and user training for systems and their life cycle processes (EIA/IS 632). This paper introduces the principles and processes of systems engineering, based on EIA/IS 632, as a methodology for the development of large-complex marine systems.

In a study, the selection of a relevant methodology cannot be determined without an effort First of all, the philosophical view or understanding of the nature of a study area will be agreed, based on which a series of judgment will be performed on a process identifying a foundation or a validity of a knowledge. The findings are as follows. First, it analyzed the trend of food serviceㆍculinary art-related studies by subject and examined its awareness. The most studies are related to trend analysisㆍfood service, 104 papers, following by financial and strategic fulfillment, 76 papers. Service quality and customer-related studies are 38, individual and organization-related studies are 31 papers, education training 18 papers, while legal review are only 2 papers. Second, for trend analysis and awareness on study methodology, research study is at the first, 39%, following by literature study, 38.7%. Most studies are performed research and literature studies together.

In this Paper, We analyzed influence Factor to TPM Performance in medium and small enterprises by empirically. By Literature survey, We hypothesize education training and 5S influence to individual improvement, independence maintenance, planning and foresight, which also influence to flexibility, total equipment performance, quality, which finally influence to lower cost, delivery date. To analyze empirically, we survey questionnaire in medium and small enterprises being below 300 people. From statistical analysis, 7 hypotheses are rejected, which is different existing research. This is analyzed that reflect actuality that medium and small enterprises is different from large enterprises. We expect that result of this treatise does concentration effort in important factor to get TPM performance in medium and small enterprises.

Wood material is positive with the concept of eco-friendly materials. Wood toy preference of foreign brands is also a real problem. Therefore, in this domestic situation on Toys Brand Development, there are many problems yet to be solved. At First, a wood material for toys requires the development of more sophisticated and precision materials. Second, new content, product development and training program development of the toys are needed. Characters and content development time and effort should be invested. In present, Korean brand development of wood toy with educational effects is very important issues as the use of wood to match the low carbon & green growth.

Our furniture industry is rapidly changing due to the declining economy. The existing weak furniture industry in Korea has yielded its inability to complete in a very competitive marketplace. The furniture companies lack the special necessary skills and professional knowledge necessary to design and manufacture furniture. Therefore, constant effort by designers and managers is needed in order to strengthen the Korean furniture industry's strategy and advance it into becoming a recognized player in the area of furniture design, worldwide, Designers has to have systematic training in order to have insight into upcoming international trends and incorporate new manufacturing techniques immediately This study will analyze the curriculums related to furniture design departments in Universities and technical schools in Germany, a leader in the furniture industry. It will present new educational ideas and program for furniture designers in the Korean universities.

Artificial Neural Networks (ANN) have the capability to develop functional relationships between input-output patterns obtained from any source. Thus ANN can be conveniently used to develop a generalised relationship from limited and sometimes inconsistent data, and can therefore also be applied to tackle the data obtained from wind tunnel tests on building models with large number of variables. In this paper ANN model has been developed for predicting wind induced pressures in various zones of a Gable Building from limited test data. The procedure is also extended to a case wherein interference effects on a gable roof building by a similar building are studied. It is found that the Artificial Neural Network modelling is seen to predict successfully, the pressure coefficients for any roof slope that has not been covered by the experimental study. It is seen that ANN modelling can lead to a reduction of the wind tunnel testing effort for interference studies to almost half.
