  • A laboratory study was made to develop a simple and economic model method for the systematic determination of functional properties of 'Soy Protein Isolates (SPI)' prepared from defatted soybean meal. These are required to evaluate and to predict how SPI may behave in specific systems and such proteins can be used to simulate or replace conventional proteins. Data concerning the effects of pH, salt concentration, temperature, and protein concentration on the functional properties which include solubility, heat denaturation, gel forming capacity, emulsifying capacity, and foaming capacity are presented. The results are as follows: 1) The yield of SPI from defatted soybean meal increased to 83.9 % as the soybean meal was extracted with 0.02 N NaOH. 2) The suitable viscocity of a dope solution for spinning fiber was found to be 60 Poises by using syringe needle (0.3 mm) with 15 % SPI in 0.6 % NaOH. 3) Heat caused thickening and gelation in concentration of 8 % with a temperature threshold of $70^{\circ}C$. At $8{\sim}12\;%$ protein concentration, gel was formed within $10{\sim}30\;min$ at $70{\sim}100\;^{\circ}C$. It was, however, disrupted rapidly at $125\;^{\circ}C$ of overheat treatment. The gel was firm, resilient and self-supporting at protein concentration of 14 % and less susceptible to disruption of overheating. 4) The emulsifying capacity (EC) of SPI was correlated positively to the solubility of protein at ${\mu}=0$. At pH of the isoelectric point of SPI (pH 4.6), EC increased as concentration of sodium chloride increased. Using model system$(mixing\;speed:\;12,000\;r.p.m.,\;oil\;addition\;rate:\;0.9\;ml/sec,\;and\;temperature\;:\;20{\pm}1\;^{\circ}C)$, the maximum EC of SPI was found to be 47.2 ml of oil/100 mg protein, at the condition of pH 8.7 and ${\mu}=0.6$. The milk casein had greater EC than SPI at lower ionic strength while the EC of SPI was the same as milk casein at higher ionic strength. 5) The shaking test was used in determining the foam-ability of proteins. Progressively increasing SPI concentration up to 5 % indicated that the maximum protein concentration for foaming capacity was 2 %. Sucrose reduced foam expansion slightly but enhanced foam stability. The results of comparing milk casein and egg albumin were that foaming properties of SPI were the same as egg albumin, and better than milk casein, particularly in foam stability.

  • Changes of chemico-physical properties and mturitiy during pig manure composting were analysed using three kinds of bulking agents with rice hull(T1), rice hull and extruding hull mixture (T2, 1:1, v/v), and extruding hull(T3). During composting process, temperature of T1, T2 and T3 were maintained over $50^{\circ}C$ for 31, 21, and 35 days respectively. Organic matter content of each treatment was decreased from 82.2%, 82.0%, and 82.8% to 70.5%, 68.9% and 69.7% and pH increased to 8.85, 9.91, and 8.80, respectively. Total nitrogen content of all treatments gradually decreased, but C/N ratio, phosphorous, and potassium content did not, show any changes during composting process. Both germination rate and early growth were tested using radish seeds for composting maturity. From those results, it was concluded that all treatments were stabilized after 45th day and extruding hull(T3) added compost was superior to others. The test of suppressive effect showed that all treatment have no effect against Fusarium oxysporum, Alternaria altemata, Botrytis cinerea. Compost supplemented with rice hull showed an inhibitory effect after 30th days, while compost supplemented with rice hull and extruding hull(T2) had an inhibitory effect during all period against Rhizoctonia solani. But treatment with extruding hull(T3) added compost did not have any inhibitory effect against Rhizoctonia solani. Only 63th samples in T1 and T2 treatment showed inhibitory effect against Colletoerichum gloeosporioides. However, T3 did not. Suppressive effect of extracts from 67 kinds of composts was investigated in vitro against plant pathogens, such as Fusauum oxysporum. Alternaria alternata, Colletotrichum gloeospoioides, Rhizoctonia solani, and Botrytis cinerea. Thirty two of them showed inhibitory effect against more than one phytopathogen, nine against one pathogen, four against two, six against three, six against four, and seven against five.

  • The effects of amylopectin and hydrocolloid (locust bean gum and guar gum) content on wheat flour dough and noodle properties were investigated. As the amount of amylopectin increased, the water absorption rate (farinograph), the tension (tension test), the gel stability (freeze-thawing treatment), and the springiness and the cohesiveness (TPA) increased, but the pasting temperature (RVA), the lightness and yellowness (color measurement), and the hardness (TPA) tended to decrease. In sensory evaluations, the scores for cohesiveness, springiness, and acceptability of cooked noodle increased as the proportion of amylopectin increased. The proper combination of amylose/amylopectin ratio and hydrocolloids improved the freeze-thaw stability and the sensory acceptability of wheat flour dough and noodle.

  • Purpose: This study was undertaken to investigate the feasibility of using automated liquid-handling systems equipped with reusable fixed tips in Radioimmunoassays and to demonstrate that the use of an automated pipetting instrument can decrease in the typical daily workload. Materials and Methods: The precisions of the automated pipettor and the manual pipettor were determined gravimetrically (n=30). A total of 30 specimens for HBs Ag were repeatedly pipetted (three replicates) with the automated pipettor and then retested. PSA samples were simultaneously pipetted with either the automated pipettor or the manual pipettor and then analyzed (n=40). Sample carryover test assessed for CA19-9, AFP and HCG when the automated pipettor was used. Pipetting speed of the automated pipettor and the manual pipettor were compared by evaluation of each workload. Results: The precisions coefficients of variation (CV) were 2.1% for the automated pipettor and 1.6% for manual pipettor. The mean cpm and CV for each group of replicates were 41,203 cpm and 3.7% for HBs Ag positive specimens, and 99 cpm and 7.9% for HBs Ag negative specimens, respectively. PSA results showed no significant differences between automated pipettor and manual pipettor (p=0.15, r=0.999). Carryover for CA19-9, AFP and HCG analytes was <0.1 ppm or below the assay limit of detection. Pipetting speed was significantly improved by using the automated instrument. Conclusion: There was no evidence that the use of an automated pipettor adversely affected any of the performance characteristics of the assay. Indeed, routine use of the Tecan automated pipettor has resulted in a decrease in the typical daily workload.

  • The demand for an environment-friendly transportation system, equipped with low energy consumption, and low-or zero-pollution has been on the increase since the beginning of the World Trade Organization era. Simultaneously, the consistent growth of high-speed tram technology, combined with market share, has sparked a fierce competition among technologically-advanced countries like France, Germany, and Japan in an effort to keep the lead in high-speed train technology via extensive Research and development(R&D) expenses. These countries are leaders in the race to implement the next-generation transportation system, build intercontinental rail way networks and export the high-speed train as a major industry commodity. The need to develop our own(Korean) 'high-speed train' technology and its core system technology layouts including original technology serves a few objectives: They boost the national competitive edge; they develop an environmental friendly rail road system that can cope with globalization and minimize the social and economic losses created by the growing traffic-congested delivery costs, environment pollution, and public discomforts. In turn, the 'G7 Project-Development of High Speed Railway Technology' held between 1996 and 2002 for a six-year period was focused on designing a domestic train capable of traveling at a speed of 350km/h combined and led to the actual implementation of engineering and producing the '2000 high-speed train:' This paper summarizes and introduces one of the G7 Projects-specifically, the design segment achievement within the development of train system engineering technology. It is true that the design aspect of the Korean domestic railway system program as a whole was lacking when compared with the advanced railroad countries whose early phase of train design emphasized the design aspect. However, having allowed the active participation of expert designers in the early phase of train design in the current project has led to a new era of domestic train development and the implementation of a way to meet demand flexibly with newly designed trains. The idea of a high-speed train in Korea and its design concept is well-conceived: a faster, more pleasant, and silent based Korean high-speed train that facilitates a new travel culture. A Korean-type of high-speed train is acknowledged by passengers who travel in such trains. The Korean high-speed prototype train has been born, combining aerodynamic air-cushioned design, which is the embodiment of Korean original design of forehead of power car minimized aerodynamic resistance using a curved car body profile, and the improvement of the interior design with ergonomics and the accommodation of the vestibule area through the study of passenger behavior and social culture that is based on the general passenger car.

  • A new and improved analytical method involving alkaline pyridine extraction was proposed to quantity chlorophyll contents in syrup and candy type chlorella products. The performance of analytical method was compared with the conventional Korea food standard method which involves acetone extraction. The application of sonication chlorophyll extraction form alkaline pyridine sample was also explored. The analytical procedure was validated by evaluating accuracy, precision and reproducibility. For liquid samples, the pyridine extraction method showed higher accuracy and precision compared to acetone extraction method. The CV values of pyridine extract method and the acetone extraction method were 18.82 and 40.0, and the accuracy to theoretical values were 106.3% and 78.1%, respectively. When sonication extraction method was applied to the pyridine extraction, the precision was improved as indicated by reduced CV values from 18.82 to 11.36. The improved performance of pyridine-sonication extraction was also validated by recovery test of chlorophyll that was previously spiked into the sample matrix. For solid matrix, the pyridine extraction method showed better performance in analysis of chlorophyll in solid food matrix (CV = 7.05) compared to conventional acetone extraction method (CV = 30.0). However, the accuracy to theoretical values of pyridine and acetone extraction methods only showed only 62.7% an 40%, respectively. The relatively low accuracy of pyridine extraction method (62.7%) was improved to 99.4% by applying additional sonication extraction method. The improved performance of applying additional sonication extraction was validated by standard deviation, CV values and accuracy to theoretical values.

  • Background: We performed a phase IV clinical trial to examine the usefulness of a continuous infusion of nicardipine hydrochloride to control hypertension in patients with acute aortic dissection. material and Method: Systolic/diastolic blood pressure, and heart rate were monitored before and after the intravenous administration of nicardipine in 31 patients with aortic diseases. The period of nicardipine administration in each patient was from 3 to 14 days. Efficacy was evaluated by determining the average amount of blood pressure reduction on the 3rd day of drug administration. The dosage of another antihypertensive agent was slowly tapered down, and ultimately replaced by the test drug. Result: 28 patients were diagnosed as acute aortic dissection, 2 patients as rupture of the aortic arch aneurysm, and 1 patient as traumatic aortic rupture. Mean age was 53.9 $\pm$ 14.9(29~89) years, and 21 patients(67.7%) were male. 14 patients(32.3%) had complications associated with underlying aortic disease: aortic insufficiency in 7, hemopericardium in 6, acute renal failure in 1, paraplegia in 1, lower extremity ischemia in 1, and hemothorax in 1. The time needed to reach the target blood pressure was within 15 minutes in 16, from 15 to 30 minutes in 10, from 30 to 45 minutes in 3 and from 45 to 60 minutes in 2, and their baseline average systolic, diastolic, and mean arterial blood pressures(mmHg) were 147$\pm$23, 82.3$\pm$ 18.6, and 104 $\pm$ 18, respectively. Average systolic, diastolic, and mean arterial blood pressures(mmHg) on the third day of nicardipine infusion were 119$\pm$ 12, 69$\pm$9, and 86$\pm$8, and they all showed statistically significant decrease(p<0.05). The average systolic, diastolic, and mean arterial blood pressure(mmHg) after the discontinuation of the nicardipine infusion were 119 $\pm$ 15, 71 $\pm$ 14, and 86$\pm$ 13, respectively. No significant difference was observed between the average pressures measured on the third day and those measured after the discontinuation of the nicardipine infusion, and no definite side effects were observed during the study period. Conclusion: Nicardipine hydrochloride was both effective and safe at controlling blood pressure in patients with acute aortic dissection.

  • The purpose of this study is to develop theme-based integrated science unit by the interdisciplinary approach and to analyze it's effects on the science achievement and the attitude towards science learning. 'Interaction' and 'Stability' were selected as the integrated themes, and the main concept and subconcept in relation to the themes were extracted from the four areas of science, and the learning contents were constructed in the integrated ways. While the main concept have relevance to subconcept in the interaction, the main concept have little relevance to subconcept in the stability. Therefore, the stability was to fit with middle school integrated science theme, but the interaction was not. The theme-based integrated science units developed was implemented in middle school, and the results are follows. First, the science achievement of group of theme-based integrated science teaching is significantly higher than those of group of traditional teaching. Second, the scores of the test of attitude toward science learning of the group of theme-based integrated science teaching is significantly higher than those of group of traditional teaching. Third, the students' perception of theme-based integrated science teaching was positive. The students have participation, interest, motivation in theme-based integrated science teaching, and students have difficulty in learning theme-based integrated science teaching.

  • 서구 근대 국제관계학의 태동은 "전쟁의 원인"을 밝혀내려고 했던 유럽 지식인들의 학문적 도전에서부터 비롯되었다고 할 수 있다. 1, 2차 세계대전의 잔혹함을 겪으면서 이들은 전쟁(특히 전쟁의 원인)에 대한 좀 더 과학적인 연구를 통해 어떻게 하면 국가들 간의 전쟁을 예방할 수 있을까에 집중해 왔다. 이러한 학문적 경향을 반영한 것이 잘 알려진 미국 미시간 대학의 "전쟁 상관성 연구 프로젝트(Correlates of War Project)"이다. 이는 나폴레옹 전쟁이 끝나고 비엔나체제가 시작된 1815년 이후 국가들 간 발생한 모든 전쟁 관련 자료를 데이터베이스화하여,국제관계학자들이 전쟁(Interstate War)이나 군사분쟁(Militarized Interstate Disputes)을 정량 또는 정성적으로 연구할 수 있도록 다양한 정보들을 제공하고 있다. 최근 Paul F. Diehl, William R. Thompson과 같은 학자들은 전쟁을 분석단위로 하는 전쟁의 원인(Causes of War)을 연구하는 학풍에서 벗어나, 국가들 간의 분쟁과 전쟁을 연구하기 위해 숙적관계(Rivalry)라는 새로운 분석의 단위를 제시하였다. 숙적관계는 국제관계에 있어서 지속적으로 분쟁 또는 전쟁을 일으키는, 즉 무력분쟁의 긴 역사를 가지고 있는, 두 국가를 일컫는다. 국가들 간의 숙적관계는 학자들에 따라 Interstate Rivalry, Enduring Rivalry, Strategic Rivalry 등 다양한 정의와 성격을 갖고 있다. 이러한 국가들의 사례로는 2차대전 이전까지 프랑스-독일 관계, 2차대전 이후 중동지역 이스라엘과 아랍국가들 간의 관계, 냉전기 미소관계, 인도-파키스탄 및 남북한 관계 등을 예로 들 수 있다. 이렇게 널리 알려진 숙적관계 외에도 남미의 칠레-아르헨티나, 에콰도르-페루와 아프리카의 소말리아-에티오피아 등 학자들에 따라 1815년 이후 약 200개의 숙적관계를 제시하고 있다. 숙적관계에 대한 연구는 기존의 전쟁의 원인 중심이었던 정량적 국제분쟁 연구에 두 국가의 분쟁역사를 포함시키는 정성적 연구를 접합시키고 있다. 본 연구는 1945년 이후 숙적관계 국가들의 관계종식과 관련하여, 거시론적이고 전체론적 접근방법(Macro - level Holistic Approach)을 제시하고 있다. 먼저 1945년 이후 발생한 국가들 간의 숙적관계 종식(Rivalry Termination)을 이해하기 위해, 거시적 관점에서 숙적관계를 발생시키게 된 역사적 원인을 살펴보고 있다. 특히 1945년 이후 숙적관계와 관련된 중요한 요인들 중에서 전쟁, 영토분쟁, 그리고 근대국가 형성에 대해 살펴보고 다음과 같은 두 가지 명제(proposition)를 제시한다. 첫째, 1945년 이후의 숙적관계 형성과 지속에는 2차대전 이후 독립국가 형성, 헌팅턴이 주장한 제3의 물결(민주화), 그리고 냉전기 미소경쟁 등의 역사적 배경이 영향을 주었다는 것이다. 둘째, 이러한 역사적 배경에 더하여 1945년 이후 숙적관계는 전쟁에 의해 시작된 숙적관계와 전쟁 없이 시작된 숙적관계 등 2가지로 나눌 수 있으며, 전쟁에 의해 시작되고 영토분쟁과 근대국가 형성 문제를 내포하고 있는 숙적관계가 그렇지 않은 숙적관계에 비해 오랫동안 지속되며 관계해결이 어렵다는 것이다. 앞서 제시된 2가지 명제들과 관련하여 본문에서는 다양한 학자들이 제시한 숙적관계 정의들에 일치하는 23개의 숙적관계(Consensus Rivalries)를 선정하여 이들에 대한 비교분석(Descriptive Analysis)을 실시하였다. 이들 사례들을 1945년 이전과 이후로 나누어, 숙적관계 형성과 종식에 있어 핵심요소인 국가들 간 힘의 차이(Power Relations), 분쟁의 주요 원인(Primary Conflict Issue), 숙적관계에 있어 다른 국가들과의 연계성(Rivalry Linkage), 전쟁의 횟수와 시기 등을 통해 비교하였다. 숙적관계의 종식과 관련하여 약소국 간의 숙적관계(Minor Dyad)가 오래 지속되고, 영토분쟁(Territorial Disputes)이 숙적관계를 지속시키는 주요인이며, 다른 숙적관계와의 연계성이 적은 숙적들이 오래 지속된다는 비교분석 결과가 나왔다. 또한 전쟁의 횟수는 숙적관계 종식에 큰 영향을 미치지 못하지만 전쟁으로 인해 시작된 숙적관계가 그렇지 않은 경우보다 더욱 오래 지속되는 것으로 확인되었다. 끝으로 2차대전 이전의 숙적관계는 대부분 전쟁을 통해 종식되었지만, 1945년 이후에는 전쟁 없이도 숙적관계가 종식된 경우가 많았음을 보여 주고 있다. 본 연구의 주목적은 "1945년 이후 형성된 숙적관계를 어떻게 종식시킬 수 있을 것인가?"라는 규범적 논제를 통해, 23개의 주요 숙적관계를 발굴하여 거시적, 역사적 관점에서 비교분석함에 있다. 이는 특히 우리나라가 처한 현실과 관련하여 중요한 시사점을 갖는다. 남북관계가 갖는 특수성보다는 1945년 이후 국제정치 역사속에서 발생한 숙적관계 현상이라는 일반성의 틀에서 남북관계를 이해하고자 했다. 남북관계를 베트남, 예멘, 독일 등 분단국가의 사례들과만 비교 연구하는 제한된 시각에서 벗어나, 인도-파키스탄, 그리스-터키, 에콰도르-페루 등 유사한 숙적들 간의 관계들과 비교하는 새로운 연구의 장을 제시하고자 한다. 따라서 앞으로 숙적관계 종식에 대한 더욱 다양화된 사례연구를 통해 한반도 분쟁해결에 필요한 새로운 교훈을 얻을 수 있을 것이다. 예를 들면 2차대전 이후 발생한 국경을 접하고 있는 비강대국들의 평화적인 숙적관계 종식에 대한 사례연구는 남북한이 앞으로 지향해야 할 방향을 제시해 줄 수 있을 것이다. 끝으로 본 연구는 특정한 정책적 함의를 도출하기 보다는 숙적관계와 관련된 하나의 거시적 이론를 제시하고, 주요 숙적관계 국가들에 대한 비교설명을 통해 현존하는 숙적관계 해결을 위한 하나의 분석의 틀을 제시하는 것으로 국제분쟁 연구에 기여하고자 하였다.
