Adzuki bean is sensitive to waterlogging stress. The overall study on the waterlogging stress is limited comparing to the study on the drought and any environmental stress. Therefore, the present study was conducted to investigate the changes in growth characteristics and the expression patterns of proteins at the 5-leaf stage periods of adzuki bean. The domestic cultivar, Arari (Miryang No. 8) was used to test the waterlogging stress. In the waterlogging treatment for 3 days, the plant height showed slightly decrease in the treatment at 3 days of waterlogging, but root fresh weight showed significantly changes at 3 days of the waterlogging treatment. Chlorophyll contents showed also significantly different at 3 days of waterlogging treatment compared to control the plants. The waterlogging stress gradually influenced the growth differences between the control and the treatment respectively. More than 350 pro- tein spots were identified on 2-D gels using an image analysis. Moreover, a total of 28 proteins were analyzed using LTQ-FT-ICR MS. Among these 28 proteins, a total of 18 proteins were up-regulated, and 10 proteins were down-regulated under waterlogging treatment. According to biological process, the most of the proteins were found to be involved in carbohydrate metabolism. Regarding the subcellular local- ization, most of the proteins were localized into chloroplasts in 5-leaf stage.

본 논문은 방송환경의 변화와 새로운 정보통신기술의 도입에 따른 새로운 방송정책의 방향을 모색해 보고 있다. 산업화된 국가의 방송정책- 특히 케이블텔레비젼과 관련하여- 에 비추어 우리의 방송정책이 추구해야 할 방송철학적 지향점을 논술하고 그 문제점을 지적하고 있다. 본 논문은 방송정책이 이제는 정권정책적 차원을 떠나서 산업정책과 문화정책의 맥락에서 이루어져야 할 것을 주장하며 그 철학적 토대를 독일의 공영방송에 비교해 보고 있다. 케이블텔레비젼의 도입을 바로 앞에 두고 정책적 틀을 점검하며 성공적인 도입에 필요한 몇가지 전제조건을 서술하였다. 고전적인 미디어 철학에 바탕을 둔 뉴미디어 정책은 실패할 수 밖에 없기 때문에 케이블 방송, 위성방송의 도입에 따른 새로운 혁신적인 방송정책이 요구되며 새로운 방송법 개정이 필요함을 논하고 있다.

遮光程度가 양하(Zingiber mioga)의 生育, 收量 및 無機成分 含量에 미치는 影響

韓海龍,張田益,朴庸奉 제주대학교 1981 논문집 Vol.13 No.-

양하는 생강과 더불어 중요한 香辛菜蔬지만 濟州道에서는 그 栽培法과 양하의 食用價値를 정확히 모르고 있다. 이에 繁殖方法의 하나로서 遮光程度를 달리하였을 경우 양하의 生育과 收量 및 無機物 含量에 미치는 影響을 調査한 結果는 다음과 같다. 1) 양하의 草長과 葉數는 遮光程度가 높을수록 增加하는 傾向을 보였으나 葉소莖과 葉幅은 生育初期에는 處理間에 비슷한 傾向을 보였으나 生育後期에는 增加하는 速度가 緩慢하였고 遮光程度가 낮을수록 增加하였다. 2) 3.3㎡當 收量은 70%遮光區에서 가장 많았고 處理區는 對照區 보다 多少 增加하는 傾向을 보였다. 3) 줄기와 잎에서는 遮光程道가 높을수록 窒素, 인산, 가리, 마그네슘, 망간의 含量이 對照區 보다 增加하였으나 鐵成分 만은 對照區의 줄기에서 가장 많은 含量을 보였다. 4) 위의 實驗의 結果 양하의 生育, 收量 및 無機成分量은 70%遮光에서 增加하였고 앞으로 遮光程度와 處理時期을 달리하여 계속 硏究할 必要가 있다고 생각된다. Among major condimental vegetables, Zingiber mioga and ginger has not yet been examined in cultivation method and contents of inorganic element in Cheju Island. This experiment therefore was carried out to investigate the effect of several shading treatments on growth, yields and contents of inorganic elements of Z. mioga. The results are as follows : 1) The higher the shading degree, the higher the plant height and leaf number, but neck diameter and leaf width showed no significant difference from the early growth period while the late growth period, the lower the shading degree, the higher the neck diameter and leaf width. 2) In the yields of 3.3㎡ unit area, the 70% shading treatment showed sligh increase in compare with other treatment. 3) In contents of the inogranic element of leaf and stem, the higher the shading degree, the higher the content of nitrogen, phosphor, potassium, magnesium and manganese, but only the iron increased in compare with other treatment at the stem of control lot. 4) The result indicated that the growth, yields and contents of inorganic element increased significantily at the 70% shading treatment. The results also point out that study of different shading degree and shading period are necssary.

CANDU형 원전에서의 유도방출한도 결정

황해룡,김교운,김종경 대한방사선 방어학회 1994 방사선방어학회지 Vol.19 No.1

CANDU형 원자력 발전소에서의 유도방출한도를 계산하기 위한 전산 코드 DRL이 개발되었다. DRL 코드에서의 유도방출한도는 CANDU형 원자력 발전소가 정상 가동될 때의 기체 및 액체 방출물에 포함된 방사성 핵종의 방출 허용 기준을 설정하기 위한 것이다. 본 전산 코드는 CSA Standard N288.1-M87에서 권고하고 있는 방법 및 다수 매개 변수를 이용하였고, 월성 원자력 발전소를 대상으로 유도방출한도를 결정하는데 이용되었다. A computer code DRL was developed to calculate the derived release limits at CANDU type muclear power plants. The derived release limits resulting from DRL code is to setguidelines for the release of radionuclides in airborne and water-borne effuents during normal operations of a CANDU type nuclear power plant. The DRL code generally follows the methodology prescribed in the CSA standard N288.1-M87 and uses the parameter values recommended in the same standards. The DRL code was used to calculate a set of preliminary derived release limits for the Wolsong NPP.

김해룡,박윤배 慶北大學校 師範大學 科學敎育硏究所 2001 科學敎育硏究誌 Vol.25 No.-

본 연구는 물리과 CAI에서 학습자 특성과 인지적 노력수준이 학업성취변화에 미치는 상호작용효과를 밝히고자 시도되었다. 고등학교 2학년 206명 (남학생 96명, 여학생 110명)에게 물리 CAI 수업을 실시하였다. 사용된 프로그램은 빛의 파동성에 관한 흑백 56프레임으로 되어 있으며, 학습자 통제형의 시뮬레이션 프로그램으로 1차시 분량이었다. 먼저 선행연구에 근거하여 학습자 특성변인들을 선정하였는데, 선정된 학습자 특성변인들을 살펴보면, 성 (남학생, 여학생), 인지양식 (장독립, 장의존), 과학에 대한 흥미 (상, 중, 하), 그리고 인지적 노력 (상, 중, 하) 수준을 선정하였고, 종속변인으로 사전사후학업성취도의 차이점수로 학업 성취변화를 선정하였다. 수업 전에 인지양식을 알아보기 위한 집단잠입도형검사지, 학업성취도 검사지, 과학에 대한 흥미 검사지를 투입하였고, 수업 후에도 학업성취도 검사지와 인지적 노력수준 검사지를 사용하였다. 자료에 대한 통계 분석 기법으로는 학습자 특성과 인지적 노력수준의 상호작용효과를 알아보기 위해 이원변량분석을 실시하였다. 본 연구에서 알아보았던, 학습자 특성과 인지적 노력수준의 상호작용효과에 관하여는 성과 인지적 노력수준, 인지양식과 인지적 노력수준, 그리고 과학 흥미수준과 인지적 노력수준의 상호작용효과가 모두 나타났다. 여학생의 경우에 학업성취의 증가는 인지적 노력에 비례하였으나, 남학생들은 무관하였다. 장독립 학생의 경우에는 학업성취의 증가가 인지적 노력에 무관하였으나, 장의존 학생을은 인지적 노력이 낮을 경우에 학업성취의 증가가 특히 작은 것을 알 수 있었는데, 이러한 현상은 여학생에게서 특별히 강하게 나타났다. 과학흥미수준이 중간 정도인 학생들의 경우 학업성취의 증가는 인지적 노력에 무관하였으나, 흥미 수준이 높거나 낮은 학생들은 인지적 노력 수준이 낮아지면 학업성취의 변화도 작아졌다. The purpose of this study was to examine interaction effects of learner's characteristics and cognitive effort level on students' achievement gain. For the study, a physics CAI was delivered to 206(96 boys and 110 girls) eleventh graders. The CAI program was 56 frames, black and white, and learner control type simulation program. It took approximately 30 minutes. The independent variables were gender, cognitive style, science interest level, and cognitive effort level. The dependent variable was students' achievement gain defined as a difference score between pre- and post-achievement test scores. Pre-achievement test, science interest test, and cognitive style test were administered before the instruction. And after the instruction, post-achievement test and cognitive effort test were administered. Data were analyzed by using two-way ANOVA. There were interaction effects of learner's characteristics and cognitive effort. For girls, cognitive effort was proportional to achievement gain, while there was no relation between cognitive effort and achievement gain in boys. When cognitive effort level was low, achievement gain of field dependence students was very low, especially for girls. Both at high and low levels of science interest, achievement gain was very low at low cognitive effort level, while achievement gain of middle level of science interest did not show any significant difference.

The spray-type protective coating film has been developed and applied for alumina, glass, wooden, and metal structures to extend the protection against the elements that cause structural corrosion and degradation. We describe the characteristics of selecting and testing additives as well as sensitivities to variations in selecting the start formulation. The product formulation is obtained by blending the theoretical together with the practical in solvent-based applications. From a commercial view point, this durable film method can effectively provide the first line of defense for complex structural shape as a barrier to the effects of water, oxygen, pollutants and microorganisms.

김해룡,이문규 연세대학교 경영연구소 2002 연세경영연구 Vol.39 No.2

서비스의 개인화(service personalization)는 최근 인터넷 마케팅 분야에서 중요한 전략적 개념으로 등장하고 있다. 본 연구에서는 이러한 개인화 서비스를 고객주도형과 서비스 제공자주도형으로 이분화하고 그 효과에 대하여 실험을 통하여 살펴보았다. 연구 결과, 개인화 서비스에 대한 전반적인 효과가 서비스 이용자의 호의적인 태도의 증가 및 플로우의 경험을 통해 입증되었으며, 특히 서비스 제공자주도형 개인화 서비스는 고객주도형 개인화 서비스가 적절히 제공되는 경우에만 고객들의 전반적인 태토에 긍정적인 효과를 가져온다는 사실이 입증되었다. 반면 개인화 서비스가 가져올 수 있는 개인정보노출에 대한 위험자각은 유의적으로 드러나지 않았다. 이외 본 연구에서는 개인화 서비스와 관련한 개념들이 정리되고 이에 대한 이론적ㆍ실무적 의미가 논의된다.

經濟發展과 社會發展 : 韓國의 事例를 中心으로 with special reference in korea

辛海龍 건국대학교 1983 論文集 Vol.16 No.1

The main purpose of this study is to grope for a formula for a balanced economic and social development through realistic approach. For this, we will review a number of theories for the economic and social development, and then, as a corroborative inquiry, begin to examine the initial conditions, strategies, and the results of the Korean economic development. We will look at the present situation of the Korean social development in terms of population growth, urbanization, housing, income distribution, and social security. We will also examine the practical aspect of "Growth First and Distribution Later" policy which has hitherto been eloquently upheld as if it were the centerpiece for the growth-oriented policies. Although there have been strident controversies over the priority of economic development and social development, it was concluded that the issues will have to be promoted simultaneously. In the formation of the national development policies and their implementation, the social development policy was given only secondary role which was supported to cope with "Fallout Problems" partially and sporadically left behind during the all-out implementation of the economic development plans. Because the issue of the social development was treated in such a secondary way, there emerged numerous contradictions in the targeted goals and in policy implementation. In a society which is economically underdeveloped, economy can be one of the most significant secondary system, but it cannot be allowed to occupy the top place in the national policies. The economic development cannot be a value above all other systems. In other words, it cannot exists at the expense of ethers. It is said that only when it comes in harmony with the simultaneously balanced progress of other systems, then it begins to beget any justifiable significance. From the discussions above, we can draw a theme for the economic and social development in Korea in the 1980's, as follows : First, we hove to firmly establish our sense of value as to what the economic development is ultimately intended, after perceiving the present identity of our nation, which is still in the process of being developed, not having passed the stage of its development. Second, based on this value standard, the policy of "Growth First and Distribution Later" which has so far been vigorously pursued will have to be analysed. In adopting and implementing future economic development policy, we should concentrate on the type of economic development strategy that are aimed at elevating the living standards of the peoples. Third, it is a well known fact that we cannot maintain a sustained economic growth without securing social stability. Therefore, we must strive to eliminate factors adversely affecting the political, economical and social stability, and take guard against clams polarization caused by maldistribution of wealth from the viewpoint of the national security. At the acme time, we will have to contrive to work out means to secure desirable social security system, readjust income distribution and help form the middle class. Fourth, we should direct our energies to securing resources necessary for the social welfare. We might as well resume to raise the national welfare funds now defunct as soon as practicable and allocate the funks to welfare projects. Finally, enactment of the fundamental welfare law along with statutes and regulations, establishment of welfare deliberation organ for the economic and social development will be carried out, in addition to establishing a special administrative institution. We should work out an institutional arrangement be as to adequately reflect the will of the people in the plans and execution of the economic and social development.

經濟政策基準으로서의 效率과 公正에 관한 硏究

辛海龍 건국대학교 1987 論文集 Vol.25 No.1

The purpose of this thesis is to analyze in depth efficiency and equity as criteria for the evaluation of economic policy. Chapter I presents introduction. Allocative efficiency and X-Efficiency are reviewed in Chapter II. In Chapter III, the concept of equity, which has been regarded as political criteria, is newly built up from the viewpoint of performance, utilitarianism and constitutionalism. Relationships between efficiency criteria and equity criteria are examined in Chapter IV. As an example of poetical application of efficiency and equity, the effect of fianial outlays upon income distribution is analyzed with cost-benefit analysis method in Chapter V. Chapter VI contains concluding discussions. The ultimate purpose of human society is to achieve "the greatest good for the greatest number" which is interpreted as the highest level of welfare for all members of human society with limited resouces. The search for assumptions and route for the achievement of the goal has long been and will ever be the subject of social science. Economic approach has proposed the two criteria of efficiency and equity in order to obtain the goal. Efficiency and equity, however, have rarely been given same weight for the past 200-year-history of economics. There were once no distinctions between efficiency and equity. At one tune economics was focused on efficiency and at another time equity was given higher priority than efficiency. So lone as both efficiency and equity are requirements for the achievement of the ultimate goal of "the greatest good for the greatest number", it is necessary to integrate the two criteria. Therefore, it should be properly understood that improvement of equity is not in trade-off relationships with equity but a requisite for the obtainment of economic efficiency or economic growth. Main guidelines of individual policies must be set up, in this context. It is desired that for the policies which bring about negative-sum, compromising ground should be found in the course of formulation of guidelines and that for those policies having positive-sum effect, the policies should be driven so as to better both the efficiency and equity. To conclude, for the integration of the efficiency of resource allocation and equity of income dis-tribution, which is the inevitable problem that modem economics has to solve, this subject should be continuously studied from the viewpoint of inter-disciplinary social science.
