In a software product line approach, developers first develop common software architecture and components by analyzing the characteristics of all software members, and then produce each application by integrating components. The approach is considered very effective means for developing and maintaining in parallel a software family of many members. Main disadvantages of this approach is that it requires a big up-front investment in preparing product line and it takes time to deliver the first version. In this paper, we present an incremental approach to the development of software family, which requires little additional cost for initial versions and allows an organization to move smoothly to full-scale product line.

This study was conducted to examine aspects of health and safety education and demand level of safety education in construction job sites in order to provide direction of safety education development. The subjects of this study were 566 workers who were working in construction job sites located in Daegu City and Kyungbuk Province. Data were collected from June 1, 2002 to August 30, 2002. The results of this study can be summarized as follows. 1. According to safety education by experience methods, the proportion of education by lecture was highest (90.6%). The proportion of education by field practice was 13.1%. 2. Among the education methods which they thought as the most desirable method, the proportion of audio-visual education was 39.4% and the proportion of education by experience was 37.5%. Those who had more monthly income and higher education level preferred audio-visual education, while those who were younger and less educated preferred education by experience. 3. In the case of the contents of the safety education which they thought as the most important one, the proportion of enhancement of safety awareness and education of risk factors was highest (24.7%). The groups of older workers, having longer working period, and belonging to higher education level preferred these contents. 4. According to the factors which were most important to increase effectiveness of the safety education were workers' voluntary participation (27.7%), 40 to 49 years old (27.7%), and monthly income of one million, five hundred thousand won to one million, nine hundred ninety thousand won (32.0%). The proportions of lower educated workers and working as daily workers were also high. 5. The variable which most influenced the safety education was age. The safety awareness of construction job sites was the second highest influential variable. From above results, it is clear that the workers' participation in the safety education was low since most of the safety educations were formal education by lecture. Although they participated in the education, the education was also not effective because they compulsorily participated in it. Therefore, it can be concluded that effective alternative policies must be formulated.

The purpose of this study was to compare kinematics of the skilled group with the corresponding of the unskilled group during the leap of the mordern dance and to investigate the effective movement patterns of the leap. The kinematic and temporal variables examined using the DLT(Direct Linear Transformation) method of three-dimensional cinematography were leap time, leap distance, leap height and body segment angles at the instants of take off, peak height and touch down. Four skilled and four unskilled groups were selected as the subjects. Two 16mm high speed cameras were used to monitor the subjects’movement patterns. T-test was used to determine if there is any significant (p<0.05) differences on kinematic variables between the skilled and unskilled groups. The conclusions obtained from the analyzed data were as follows; (1) There were not any significant differences between two groups for the angles of body segment at the instant of take off and leap distance. (2) At the instant of peak height, the leap angle and the left ankle angle for the skilled groups were larger than for unskilled groups. (3) At the instant of touch down, the trunk angle in the sagittal plane for the skilled groups were larger than for unskilled groups. (4) The flight time and height for the skilled groups were longer and higher than for the unskilled groups.

The purpose of this study is to measure the changes of regional cerebral blood flow (rCBF) and blood pressure (BP) of Cortex Acanthopanacis in rats, and to determine the effect of Cortex Acanthopanacis on phenylephrine (PE) induced contraction of isolated rat thoracic aorts. The measurement was continually monitored by laser-doppler flowmeter (Transonic Instrument, USA) and pressure transducer (Grass, USA) in anesthetized adult Sprague-Dawley rats through the data acquisition system composed of MacLab and Macintosh computer. Contractile force was measured with force displacement transducer under 1.5 g loading tension. The result of this experiment was as following; 1. Cortex Acanthopanacis did not effect the changes of rCBF and blood pressure significantly. 2. Contractions evoked by phenylephrine were decreased significantly by Cortex Acanthopanacis 3. L-NNA, ODQ, atropine and indomethacin significantly altered the relaxation of Cortex Acanthopanacis. 4. Propranolol did not change the relaxation of Cortex Acanthopanacis. These results indicate that Cortex Acanthopanacis did not change the rCBF and BP, but Cortex Acanthopanacis can relax PE induced contraction of isolated rat thoracic aorta and that this increasing contraction related to endothelium and various mechanism.

정어리 냉동고기풀의 최적 가공조건은 원료 정어리를 알칼리 염수수세한 후 정어리 육에 대해 분리 대두단백질:물:정제 정어리유(1:5:2.6)로 만든 유화커드를 20%, 솔비톨 4%, 설탕 4%, 중합인산염 0.2% 및 항산화제로서 에리소르빈산나트륨을 0.1% 첨가하여 고기갈이한 후 -35℃에서 급속동결시켜 carbon box로 포장하여 동결저장한 제품이 가장 좋았다. 본 제품의 수분 함량은 73.3%. 조단백질 15.0%, 조지방은 6.9%였으며, 생균수는 1.6~l.8X10^4/g으로 동결저장 중 변화는 거의 없었다. 제품의 주요 구성지방산은 16:0, 16:1, 18:1, 20:5 및 22:6 등으로 고도 불포화지방산이 47.7% 함유되어 있었다. 동결저장 중 120일 동안 제품의 물성, 지질산화 및 지방산의 변화 등을 측정한 결과, 유화커드와 에리소르빈산나트륨을 첨가함으로서 동결저장 중 단백질 변성, 지질의 산화 및 변색을 효율적으로 억제 시킬 수 있었으며, 품질이 안정하게 유지되었다. 한편, 본 시제품과 명태 냉동고기풀을 혼합하여 가공한 어묵의 품질을 측정한 결과, 어묵의 품질에 큰 저하됨이 없이 명태 고기풀을 본 정어리 고기풀로 40%까지 대체할 수 있었으며 어육의 풍미를 갖는 연제품을 가공할 수 있다는 결론을 얻었다. The processing conditions and quality of sardine surimi were examined: Raw sardine meat was separated, washed in 0.2% NaHC0_3 and 0.15% NaCl solution, and then dewatered by centrifuge. The dewatered sardine meat was chopped, mixed with 20% emulsion curd (soybean protein : water : refined sardine oil= 1 : 5. 2.6), 4% sorbitol, 4% sucrose, 0.2% polyphosphate and 0.1% sodium erythorbate by stone mortar. The mixed sardine meat was frozen with contact freezer, packed in carton box and then stored at -25±2℃. The moisture, crude protein and lipid contents of the sardine surimi product was 73.3%, 15.0% and 6.9%, respectively. Fatty acid composition of product consisted of 28.8% of saturates, 24.3% of monoenes and 47.7% of polyenes and the major fatty acids were 16:0, 20 5, 18:1, 22:6 and 16:1. The results of changes in POV, TBA value, fatty acids, texture and sensory score of products during frozen storage showed that lipid oxidation and freeze denaturation of product could be retarded, and flavor enhanced by addition 20% emulsion curd and 0.1% sodium erythorbate. In an attempt to apply sardine surimi in producing surimi-based product, it was concluded that Pollack surimi could be substituted with sardine surimi up to 40% without showing any significant changes in texture and taste of surimi-based product.

가다랑어 혈합육을 보다 효율적으로 이용하기 위한 일련의 기초연구로서, 가다랑어 혈합육의 지질성분, 함질소엑스분 및 구성아미노산 등을 보통 육과 함께 분석하여 비교, 검토하였다. 보통육은 혈합육에 비해 수분, 조단백질 함량은 약간 많은 반면, 조지방과 회분 함량은 혈합육이 약간 많았다. 휘발성염기질소량은 보토육이 22.7mg/100g, 혈합육이 46.9mg/100ㅎ으로 혈합육이 보통육에 비해 선도저하가 훨씬 빨랐다. 보통육과 혈합육의 총지질 조성은 각각 중성지질 79.7%, 71.9%, 당지질, 6.8%, 9.5%, 인지질13.5%, 18.6%로 이루어져 있었다. 중성지질의 성분은 free fatty acid ac triglyceride, 인지질은 phosphatidyl ethanolamine, phosphatidyl, 인지질은 phosphatidyl choline이 주성분이었고, lysogud 인지질의축적도 확인되었다. 총지지르 중성, 당 및 인지질의 축적도 확인되었다. 종지질, 중성, 당 및 인지질의 지반산 조성에서 보통육은 16:0 및 18:1을 주체로 한 포화산 및 모노엔산의 조성비가 혈합육보다 높았으며, 혈합육은 폴리엔산, 특히 22:6의 비율이 월등히 높았다. 16:0. 18:0, 18:1, 20:5 및 22:6 등이 주요 구성지방산이었다. 유리아미노산의 조성은 총함량에서 보통육 쪽이 많았고, 보통육에는 histidine, 혈합육에는 tauring의 보통육에서는 680.9mg.100g 정도 전존해 있었으나, 혈합육에서는 IMP의 분해가 급속히 진행되어 73.1mg/100g에 지나지 않았다. TMAO 및 TMA는 보통육에 비해 혈합육에 휠씬 많이 함유되어 있었고, total creatinine은 보통육 쪽이 많았다. 구성아미노산의 조성은 양시료 간에 별차이가 없었고, glutamic acid, aspartic acid, lysine, leucine, alanine, isoleucine 및 arginine 등이 주요 구성아니노산이었다. The lipid components, nitrogenous extracts and amino acids of dark muscle(DM) of skipjack (Katsuwonus pelamis) were analyzed and compared with those of white muscle(WM). WM was higher in moisture and crude protein content, and lower in crude lipid and ash content than those of DM. Contents of volatile basic nitrogen in WM and DM were 22.7mg/100g and 46.9mg/100g. Total lipid(TL) of WM and DM consisted of 79.7%, 71.9% neutral lipid(NL), 6.8%, 9.5% glycolipid(GL), and 13.5%, 18.6% phospholipid(PL), respectively. NL was mainly composed of free fatty acid, triglyceride, and PL was mainly occupied by phosphatidyl ethanolamine, phosphatidyl choline. Also lysophosphatidyl choline and lysophosphatidyl ethanolamine were identified in PL. In fatty acid composition of TL, NL, GL and PL, WM revealed higher contents in saturates and monoenes such as 16 : 0, 18 : 1, while DM showed higher contents in polyenes such as 22 : 6 especially. The major fatty acids of these samples were generally 16 : 0, 18 : 0, 18 : 1, 20 : 5 and 22 : 6. Contents of total free amino acids from WM and DM were 5,982.3mg/100g and 4,450.7mg/100g (dry base). Of free amino acids, Tau concentration was much higher in DM than in WM, Ala, Gly, Met, Arg, Thr were also high in DM. But His was much higher in concentration in WM. Content of inosinic acid(IMP) in WM(680.9mg/100g) was higher than that of DM(73.1mg/100g). The degradations of IMP proceeded very rapidly in DM. DM contained much higher trimethylamine oxide and trimethylamine than those of WM. The profile of combined amino acids in these samples were very similar, and main amino acids were Glu, Asp, Lys, Ala, Ile and Arg.

L´accord grammatical et le sens du franc¸ais

BOK, Sung-Gyu 서울대학교 불어문화권연구소 2002 불어문화권연구 Vol.12 No.1

불어의 일치현상에는 세 가지 유형이 있다. 형태상 일치 accord morphologique, 의미상 일치 accord se´mantique, 그리고 무일치 accord meutralise´ ou invariabilite´가 바로 그것이다. 이는 지금까지 전통문법이나 기타 현대 언어학의 어떤 유파에서도 주장된 내용이 아니다. 본고는 이에 관한 것을 논하고자 하는 것은 아니고 의미가 불어의 일치에서 차지하는 역할과, 의미라는 조금은 막연한 모습을 구체적으로 들여다보는 것을 목적으로 하였다. '의상상 일치'에서 의미를 이루고 있는 것이 무엇인가를 밝히기 전에 형태상 일치와 의미상 일치의 차이를 말하는 것도 한 순서이고, 우리의 본래의 목적을 향한 좋은 출발일 것이다. 양자 사이에는 몇 가지 차원에서 차이점이 존재하나 가장 근본적인 것은 지배어 terme dominant와 피지배어 terme domine´ 사이에 문법적 차원 -즉 성과 수 또는 인칭-에서 일어나느냐의 여부이다. 형태상 일치는 지배항과 피지배항 사이에 완전한 범주의 일치가 존재하나 의미상 일치는 그 불일치가 마침내 의미의 일체에 자리를 내어준다. 기타 양자 사이의 다른 점은 언어의 존재양태에서도 찾을 수 있다. 다시 말해서 형태상 일치는 주로 문법의 세계에 머무르나 의미상 일치는 주로 담화 속에서 그 기능을 충분히 찾을 수 있다. 또한 지배어의 언어적 구조가 복잡하면 복잡할수록 의미상 일치가 이루어질 가능성을 높아진다. 우리는 풍부한 실증을 통하여 의미를 빚어내는 재료들을 모을 수 있었다. '의미상 일치'라는 한 종류의 일치에서 '의미'는 문맥치 valeur contextuelle, 지시치 valeur re´fe´rencielle, 강조치 valeur d'insistance 그리고 경제치 valeur d'e´conomie 등의 반영으로 나타난다. 그리고 일종의 사족이지만 이 의미라는 것은 일치에 직접 그 모습을 드러낼 수는 없고 -만약 그렇지 않다면 언어의 정의는 다른 것일 테지만- 일종의 문법표지 marques grammaticales를 통해서 구현된다. 한편에는 규칙적용의 기계적 자동성, 즉 형태상 일치가 있는 반면에 선택의 가능성을 전제한 의미의 우월성 또는 발화자의 의도에 따른 일치, 즉 의미상 일치가 현대 불어에서 일상적으로 실현되고 있다.
