  • This paper empirically investigates the rates of embodied technological change and their relative contributions to total factor productivity growth for manufacturing, using the Korean plant-level manufacturing data for the period of 1985-2003. We adopt a production-based estimation method proposed by Sakellaris and Wilson (2004) in order to examine the marginal productivity increase of each vintage of equipment over time. We find that the rate of embodied technological progress of Korea's manufacturing sector maintains the annual average level of 13.7 percent from 1985 to 2003, slightly lower than 16.9 percent of the U.S., estimated by Sakellaris & Wilson (2004). While the rate recorded a remarkable increase after the 1997 financial crisis, IT-producing and IT-using industries achieved higher rates of embodied technological progress than non-IT counterparts.

  • Objectives : This study was conducted to examine the clinical effects of thread embedding acupuncture on lumbar herniated intervertebral disc patients. Methods : This is a retrospective study based on clinical charts. Despite the treatments of acupuncture, pharmacopuncture, herbal medicine, and physical therapy during admission period, 10 lumbar herniated intervertebral disc patients who had shown few improvements in their symptoms were selected as subjects. Thread embedding acupuncture was conducted to reduce patient pain. Patient progress was categorized into three periods based on when the embedding procedure performed. Verbal numeric rating scale (VNRS), Oswestry disability index (ODI), and a 5 step evaluation scale for satisfaction were used to analyze the outcome. Results : Regarding comparison of VNRS improvement rate, both 3 and 6 days after embedding progress showed significant difference compared to before embedding progress. ODI improvement rate showed significant difference only 6 days after embedding progress. Patients' satisfaction with treatment had increased by several degrees. Conclusion : Thread embedding acupuncture for lumbar herniated intervertebral disc patients may be effective in reducing pain and improving their quality of life.

  • Onbyeong(溫病) is called an acute epidemic febrile disease caused by warm pathogen, a major symptom of Onbyeong is high fever. Doctrine of Onbyeong is a study of an occurrence, progress and treatments of an acute epidemic febrile disease. Doctrine of Onbyeong is valid in the Cheong Dynasty at China. Now, a theory of doctrine of Onbyeong at China and Korea is being applied in not only an acute febrile disease but also many other lifestyle diseases. Onbyeongjobyeon is a book written by Oguktong(吳鞠通). Oguktong was influenced by Jangjung-gyeong(張仲景) "Sanghanron(傷寒論)". Oguktong had organized Seopcheonsa(葉天士)'s medical thoughts and Oguktong's medical experiences. A Samcho(三焦) deteriorated case is divided into three groups - Upper, Middle and Lower-energizer - that is discussed of a vertical progress of Onbyeong. And a Wigiyeonghyeol(衛氣營血) deteriorated case is divided into four groups - Wi, Gi, Yeong and Hyeol - that is discussed of a horizontal progress of Onbyeong. In Korean medicine, there are four types of diagnosis which are watching, listening, asking and taking. Informations, got by four types diagnosis are synthesized and classified for medical treatments. A pulse diagnosis belongs to a method by taking a wrist among four diagnosis. A Korean Medicine doctor makes a conclusion of cause, region and condition of disease by taking a pulse. Because all organs in human body are connected by a meridian system. organs conditions are reflected in a meridian system. So by taking a pulse, a progress and a prognosis of disease is diagnosed In this thesis, by taking a pulse on "Onbyeongjobyeon(溫病條辨)", a location and a feature of disease's cause with weakness and strength of a vital force are examined, and a character of a pulse diagnosis of Onbyeong is examined.

  • Late blight of potato caused by Phtophthora infestans is one of the most destructive disease in organic farming as well as in the conventional cultivation in Korea. Incidence and progress of the disease largely depend on climatic conditions around the fields. However, the disease completely destroys whole leaves of the plant within two weeks in organic farming fields. While, potato leaves in conventional farming fields remain healthy for 5 weeks after the first symptom appearance, because fungicides were applied four times in average to control the disease. Area under disease progress curve (AUDPC) of organic farming fields ranged from 2314 to 2421 and quickly expanded compare to that of conventional farming fields. The tuber yield in the organic farming fields ranged from 0.96 ton per 10a to 1.5 ton per 10a, while it was 2.7 ton per 10a in conventional farming fields. Tuber yields were reduced to $42\~63\%$ by the infection of late blight and the reduction rate was closely related with the time of first occurrence of the disease in organic farming fields. Physiological races of the pathogen were diversified with R0,1,3,4,5,7,10,11 in organic farming fields at Hongchun area. Pathogen races were distributed with similar pattern at different areas of organic farming fields.

  • In construction projects, it is very important to evaluate the performance of works in comparison with the cost and schedule plans. So, on the first of July, 2000, the Ministry of Construction and Transportation announced the EVMS will be applied in public sector soon. However there are still many arguments about how to establish the Performance Measurement Baseline(PMB) and how to evaluate the progress with accuracy. And many people confuse the meaning of EVMS with that of cost and schedule management. So, the purpose of this research is to propose the new useful methods to set up the PMB and to assess the exact progress in consideration of cost, schedule, and float time for successful implementation of EVMS.

  • Recently construction companies' capital condition has been aggravated due to low profit, fierce competition and market contraction. For this reason, the companies rely on public construction projects that protect construction fee by regulations. Despite these regulations, problems regarding progress payment are constantly happening. Also, insufficient analysis on interaction between contractors makes policy making difficult. Thus, in this study, interaction between contractors are quantitatively determined according to delay of application and payment based on current public construction regulations on construction stage. A system dynamics model is used, which analyzes the problems based on an interaction between contractors, and solutions for progress payment application and payment delay are suggested according to the research results.

  • In domestic public works, there are several problems in the measurement of payments based on the bill of quantity, which doesn't match with the activity progress rate, heavy paper works and complicated procedures. It can be classified formal and simplified method. By using the simplified method, it can be solved many problems by summarizing the procedure, but is not generally used. This paper proposes a payment method by progress measurement for specified activity based on WBS(Work Breakdown Structure) verifying efficiency which reduced cost account and advanced work on payment compare to method of domestic public works using the data about construction of eco-river. This method will be an important contribution on being a base for cost-schedule integrated management which were verified and also improving efficiency on measuring payment.

  • The rate of carbonation is usually low in the natural environment due to the low $CO_2$ concentration in the atmosphere. Therefore, investigation of carbonation is usually conducted under accelerated testing conditions so as to speed up the process. This study is to predict carbonation progress by mathematical model, based on the diffusions of $CO_2$ and its reaction with $Ca(OH)_2$ in carbonation progressing region, in the atmosphere. To predict of carbonation progress in the atmosphere, we adopted a diffusion coefficient of $CO_2$ that agreed well the experimental value obtained by the accelerated carbonation test. Consequently the model can predict the rate of carbonation of concrete exposed in the atmosphere regardless of finishing materials.
