        The IRR(internal rate of return) is often used by investors for the evaluation of engineering projects. Unfortunately, it has serial flaws: (1) multiple real-valued IRRs may arise; (2) complex-valued IRRs may arise; (3) the IRR is, in special cases, incompatible with the net present value (NPV) in accept/reject decisions. The efforts of management scientists and economists in providing a reliable project rate of return have generated over the decades an immense amount of contributions aiming to solve these shortcomings. Especially, multiple internal rate of returns (IRRs) have a fatal flaw when we decide to accep it or not. To solve it, some researchers came up with external rate of returns (ERRs) such as ARR (Average Rate of Return) or MIRR (MIRR, Modified Internal Rate of Return). ARR or MIRR. will also always yield the same decision for a engineering project consistent with the NPV criterion. The ERRs are to modify the procedure for computing the rate of return by making explicit and consistent assumptions about the interest rate at which intermediate receipts from projects may be invested. This reinvestment could be either in other projects or in the outside market. However, when we use traditional ERRs, a volume of capital investment is still unclear. Alternatively, the productive rate of return (PRR) can settle these problems. Generally, a rate of return is a profit on an investment over a period of time, expressed as a proportion of the original investment. The time period is typically the life of a project. The PRR is based on the full life of the engineering project. but has been annualised to project one year. And the PRR uses the effective investment instead of the original investment. This method requires that the cash flow of an engineering project must be separated into ‘investment’ and ‘loss’ to calculate the PRR value. In this paper, we proposed a tabulated form for easy calculation of the PRR by modifing the profit and loss statement, and the cash flow statement.

        This study introduces the methods to apply and develop the integrated Cost of Quality (COQ) and Time-Driven Activity-Based Costing (TDABC) model for seeking not only quality improvement but also reduction of overhead cost. Inefficient and uneconomical COQ activities can be identified by using time driver which also maximizes the quality improvement for Prevention-Appraisal- Failure (PAF) quality costs. In contrast, reduction of the indirect cost of unused capacity resource using Quality Cost Capacity Ratio (QCCR) of TDABC minimizes overhead cost for COQ activities. In addition, linkage between Overall Equipment Effective (OEE) and Time Driver develops the integrated system of Total Productive Maintenance (TPM) and TDABC model. Lean OEE maximizes when an Unused Time (UT) of TDABC that are TPM losses and lean wastes reduces whereas the TPM Cost Capacity Ratio (TCCR) of TDABC minimizes indirect cost for non-value added TPM activities. Numerical examples are derived to better understand the proposed COQ/TDABC model and TPM/TDABC model from this paper. From the proposed model, process mapping and time driver of TDABC are known to lessen indirect cost from general ledger of comprehensive income statement with a better quality innovation and improvement of equipment.

        This article reports on a study that compared EFL freshman university students’receptive and productive recall vocabulary knowledge and their ability to use that knowledge, as it remains unclear in the literature to what extent knowledge of vocabulary, especially productive knowledge, is indicative of learners’ ability to use vocabulary to communicate. The study first measured the vocabulary size of 169students from 24 majors. Next, deeper meaning word knowledge and vocabulary userelated knowledge were assessed by administering depth tests to 51 of the students who completed the size tests. The study found that the participants were able to use only 60.3% of the words that were known receptively and productively on the size tests, and that receptive deeper meaning vocabulary knowledge was 43.0% greater than productive knowledge. Finally, the study results support the concept of a vocabulary knowledge continuum, but highlight the importance of including both receptive and productive knowledge, as they were found to develop in a dissimilar manner.

        While the number of English-medium instruction (EMI) courses has increased in many EFL universities, relatively little attention has been paid to students who encounter language difficulties in EMI courses. In order to develop language support programs for Korean undergraduate students in foreign professors’ EMI courses, this study collected and analyzed the syllabi of target courses to identify what English language skills are necessary for these courses. Findings suggest that priority should be given to teaching research-oriented English skills such as academic writing skills, with particular emphasis on how to use primary and secondary sources. Furthermore,students need to acquire speaking skills based on an understanding of readings or lectures so as to participate in discussions and to make presentations. Given the greater number of opportunities to interact with foreign professors, it is necessary as well to teach the appropriate mode of speaking to them. This study also discusses the potential of syllabus analysis as a method to complement needs analysis and to develop language support programs for specific contexts.

        Due to the competition between the various professional events, it is imperative for the team's management to improve efficiency by removing the inefficiencies of the professional team in order to gain a competitive edge. This study use different Data Envelopment Analysis (DEA) models to measure the efficiency of professional sport organizations. In this mathematical-analytical study, this study first reviews the related literature to analyze the input/output variables. In the end, the variables were detected and the data for this study were gathered from the Korean Basketball League (KBL). While previous studies examine relative efficiency of Korean Professional baseball teams by using CCR model, this study fully utilize the DEA method to investigate Korean professional sports organizations' operating problem. Thus, this study propose full results of DEA analysis such as efficiency score (overall, technical, and scale efficiency), slacks in inputs and outputs of inefficient organizations, Malmquist index) As a result, this study provides not only the exact productivity information of a team and a way of improving a firm's productivity with a decision maker.

        Limited research on the PYLT (productive Vocabulary Levels Test) stimu lated the investigation into the relationship between the PYLT and Korean col lege students' productive vocabulary use in writing. For the purpose of the study, twenty five students (n=25) were asked to take the PVLT, perform translation tasks, and write an essay. They were also asked to write a reflection paper to examine their perceptions of the PVLT. The LFP (Lexical Frequency Profile) was employed to analyze the students' compositions to examine the relationships between their vocabulalY profiles and the PVLT. The results of the study indicated that there was no significant correlation between the PYLT and the LFP; the relationships between the PVLT and other variables were largely influenced by word frequency levels. These findings imply that the PVLT at the 2000 word frequency level represents the students' vocabulary knowledge in their compositions, and their writing proficiency. As for the perceptions of the PYLT, most of the students responded that the PVLT assessed their vocabulalY knowledge. Interestingly, they attributed both success and failure in providing correct answers to the test format of the PVL T. This study suggests that interpretation of the results of the PYLT should be associated with word frequency levels.

        The realization that there is a mismatch between the vocabulary level presented in the Korean National Curriculum, and the required vocabulary size for EFL (English as a Foreign Language) high school learners to take the high-stakes Korean College Scholastic Ability Test stimulated the researchers of the present study to administer an assessment of Korean high school learners’ vocabulary sizes. Measurement of vocabulary knowledge was conducted with the adaptation of Nation’s bilingual vocabulary size test, receptive and productive, by improving construct validity of the items. Learners were tested for the 1st ~ 10th 1,000 word bands to ascertain learners’ vocabulary size at each level. The assessment of vocabulary size demonstrated receptive vocabulary knowledge to be as large as 6,000 words. However, unforeseen rises in the EFL learners’ vocabulary sizes at some word bands were observed, which seem to have emerged from the educational milieu and the predominant focus on receptive lexical knowledge and the testing of them. Suggestions are proposed for the revision of word list of the National Curriculum, which would become the blueprint for controlling vocabulary level in the development of national textbooks of English.

        The purpose of this study is to show that using practical vocabulary learning activities can stimulate EFL learners" vocabulary enhancement through making sentences. Language practice with productive lexical output can be a very helpful way for EFL students to integrate their prior linguistic knowledge with newly-gained words, which will enhance their communicative performance. One hundred twenty students (n=120) performed two different activities (sentence-building with instructional feedback and rote-memorization), and their performances were examined by the text length in terms of lexical proficiency. The results of this study reveal that the experimental group (n=60) with sentence-building with instructional feedback seemed to evoke their lexical input and output together and did better at both than the control group (n=60) with rote-memorization. In vocabulary knowledge enhancement, the experiment group showed that they were likely to transfer a large amount of vocabulary they practiced to their language output effectively. With respect to vocabulary performance, the experimental group formed more meaningful structures with a longer sentence than the control group. This study implies that sentence-building as a language practice can be an effective way to incorporate a learner"s lexical knowledge into meaningful language use, and can lead to better communicative performance in English.
