  • The DMAIC methodology, which is most familiar to battery production system developers, is partially inadequate in its conformity to utilize battery production system tasks, so it is necessary to improve the function and structure of the methodology, but many battery production system developers use the DMAIC method based on experience, causing side effects such as confusion, delay in tasks, and insufficient performance during tasks. Accordingly, we intend to conduct an empirical study to improve the "efficiency improvement and conformity evaluation method" so that the DMAIC methodology can be used more reasonably and easily. Using the three-stage research model, we derive components that affect conformity through literature and questionnaire surveys in the first stage, use relational characteristics between components in the second stage to confirm the effect on conformity, and use the relational characteristics in the third stage to confirm the possibility of improving efficiency by applying them to the DMAIC methodology in actual cases. Finally, the "Conformity Assessment Index (CAI) equation" based on relational characteristics is established to enable effective conformity evaluation and continuous improvement.

  • This study proposed a procedure to improve the error defection of attached cadastral maps using digital map data. In addition, this study also provided the direction for the accuracy improvement of attached cadastral maps by comparing analysis methods. - such as centroid, Lee Sallee shape index, and area index. The analysis is performed as follows. First, by using centroid measurement, the center point of cadastral maps and attached cadastral maps are compared. Secondly by using Lee Sallee shape measurement, the location accuracy of range area is investigated. Thirdly, by using area measurement, the range area within allowable error scope is verified. Based on analysis, the discrepancy between cadastral maps and the attacked cadastral maps are detected as follows; 98.2% from Lee Sallee shape index, 41.8% from centroid, 15.4% from area index in the whole error.

  • Rapid increase in population growth has made the mankind to delve in appropriate identification of individuals through biometrics. Foot Print Recognition System is a new challenging area involved in the Personal recognition that is easy to capture and distinctive. Foot Print has its own dimensions, different in many ways and can be distinguished from one another. The main objective is to provide a novel efficient automated system Segmentation using Foot Print based on structural relations among the features in order to overcome the existing manual method. This system comprises of various statistical computations of various foot print parameters for identifying the factors like Instep-Foot Index, Ball-Foot Index, Heel- Index, Toe- Index etc. The input is naked footprint and the output result to an efficient segmentation system thereby leading to time complexity.

  • Purpose - This study undertakes to examine the automotive trade structure between Korea and Russia to accelerate economic cooperation and pinpoint trade discrepancies to increase trade volume through improved policies, eventually finding ways for trade expansion. Research design, data, and methodology - To analyze trade decision factors for both countries, the Index of trade specialization invented by trade specialization theory, is used. Although specific factors should materialize in the trade decision analysis, realistically, concrete explanations are difficult as many unsolved factors are involved as well as their complexities Results - First, to assess comparative market competitiveness, the Index describes A value/B value, representing the Korean versus the Russia market share and the Korean market share versus the world. Second, the index shows that Korea is taking comparative advantage of its export specialization. Third, the RCA indices show considerable improvement compared to 2000. Conclusions - This research used a quantitative approach to examine trade specialization and examined a comparative advantage index of market share to see how inter-trade relations have changed over the past 10 years.

  • Dose-dependent responses indicated by the increase of leukocyte, peritoneal exudate cell and weights of immunorgans revealed the improvement of immunity. In the effect of macrophage on phagocytes, there were not substantial differences in the phagocytic and corrected phagocytic index. The administered group being compared with the controlled group, there were no significant changes in SGOT, S-GPT, alaline phosphatase, total protein, albumin, globulin, cholesterol, triglyceride, blood urea nitrogen and glucose. Key words: dose-dependent responses, peritoneal exudate cell, phagocytic idex, corrected phagocytic index.

  • The management systems of defense projects need to be well-maintained because of huge cost and long-terms of acquisition & operation in conducting defense acquisition. In this paper, we use a structural equation model(SEM) to develop an project management index(PMI) for effective defense project. The concept of a customer satisfaction index is used to assess the PMI for strategic improvement plans for various characteristics of project management. It is expected that our model can be used to evaluate and improve the project management capability of defense acquisition.

  • The construction failures can be decreased through continuous improvement of construction process based upon the information of construction failures. Herein, the information of construction failures can be utilized as the key factor for identifying and enhancing various ineffective construction processes that can prevent failures. This research proposes a process model for the continuous improvement of construction processes by using construction failure information. Extensive reviews and analyses of literatures related to construction failures are performed to investigate its definition, type, cause, and lessons learned. This research adapts process modeling methodology and case-based reasoning for the development of the proposed CIMCP(continuous improvement model of construction process), and then suggests its framework that contains modules of case retrieval, case index, and case adaptation.

  • In the paper, the differential detection techniques of 3-h CPM signals whose modulation index is varied periodically are proposed and their error performances are analyzed. We select the modulation index sets which are proper to the differential detection and propose the differential detectors which detect symbol with 3 bits per smapling period of 3T and detect a bit per sampling period of T. Applying the nonredundant error correction circuit and viterbi algorithm to differential detection of 3-h CPM. We ascertain the error performances are improved.

  • Herniation of intervertevral disc(HIVD) is the most common disease causing low back pain. Acupuncture, electroacupuncture and moxibustion has been used for treatment of HIVD. Bee venom (BV) also has been traditionally applied to relieve pain. Recently, it has been reported that BV is effective in treating HIVD. But more objective methods were required to assess the efficacy of BV on HlVD. So we assessed of BV-acupuncture effect on herniated disc patients by use of rating scale for low back pain. We researched 22 patients who were treated at Department of Acupuncture & Moxibustion, Kyung Hee Medical Center from January 1999 to June 1999. The patients were diagnosed by MRI as having a herniated disc. The results of treatment using rating scale for low back pain in HIVD showed that $43.77{\pm}14.39$ point of pre-treatment score and $84.5{\pm}3.97$ point post-treatment score. The improvement index showed $0.43{\pm}0.15$. Especially, clinical score of neurologic deficits showed most highest improvement index of $0.7{\pm}0.45$. Assessment of BV-acupuncture Effect by MRI finding were showed that protruded disc and extruded disc got more higher improvement index than bulging disc. Among 22 patients, satisfactory assessment of BV-acupuncture effect showed that 15(68.2%) were excellent, and 7(31.8%) were good. The result suggest that BV-acupuncture is good method for treatment of HIVD.
