The intense absorption band in UN region of charge transfer complex of tetrahydrozoline with iodine in chloroform medium were utilized in a sensitive spectrophotometric determination of tetrahydrozoline hydrochloride. Alkaline aquous solution of tetrahydrozoline hydrochloride were extracted throughly to chloroform ?? tetrahydrozoline base, the layer is mixed with iodine in chloroform, and formed charge transfer complex of faint yellow solution showed absorption maxima at 293nm. Quantification range of tetrahydrozoline hydrochloride is 7.5×??mole∼1.35×10??mole at the absorption maxima. The binding ratio of this charge transfer complex were determined as tetrahydrozoline base-1 by means of mole ratio and continuous variation methods. The methods can be applied to quantitative analysis of tetrahydrozoline hydrochloride containing chloroform extracts obtained in pharmacopoeial assays.

具滋玉,金容在,李載窪 全南大學校 農漁村開發硏究所 1978 農業科學技術硏究 Vol.13 No.-

統一系 水稻 品種群의 多收性과 擴地域性을 湖南地域에서 再判斷하고, 그 妥當性의 科學的인 根據가 어떤 增收要因에 의하여 成立되는 가를 日本型 品種群 對比로 分析 檢討하기 위하여 1970年 以後 6個月間에 걸쳐 湖南地域內의 各 硏究機關에서 遂行한 試驗成績을 綜合整理하고 分析한 結果, 다음의 結論을 얻었다. 1. 窒素·燐酸·加里 增施에 따라 兩品種群 共히 高度의 有意性 있는 收量增大를 보였다. 窒素에 의하여는 兩品種 모두 直線的인, 燐酸·加里에 의하여는 曲線的 收量增加를 招來하는 結果였는데, 窒素의 境遇 統一系는 穗數와 顯花數가 增大됨으로써, 그리고 日本型은 穗數의 增大를 通하여 增收된 것이다. 燐酸의 경우는 統一系에서 穗數와 顯花數, 日本型은 顯花數와 登熟向上을 通하여, 그리고 加里增肥에 따라 統一系는 顯花數, 日本型은 穗數와 粒重을 通하여 收量을 增加시켰다. 2. 施肥에 따른 增收效率은 燐酸이나 加里보다 窒素가 높은 편이었고, 日本型보다는 統一系의 收量反應이 높았는데 이는 施肥反應으로서의 增收幅보다 基本生産性의 差異에 더욱 의존되는 傾向이었다. 3. 3要素 施肥에 따른 收量과 構成要素間의 單純相關 分析結果, 統一系의 收量은 面積當 顯花數가, 日本型에서는 面積當 穗數가 높은 正의 相關을 보였다. 즉 日本型의 境遇, 穗數와 顯花數間의 逆相關 때문에 面積當 顯花數의 收量相關이 떨어졌다. 이는 先行形質들(穗數, 顯花數)의 效率이 後行形質들(登熟, 粒重)의 效率보다 收量에 關係가 큰 것으로 나타났다. 4. 3要素 增施에 따른 收量成立特性(重回歸·重相關)은 다음과 같았다. 統一系 : Y=20.3xi**+3.9x2**+22.4x3**+3xt**-783.1 日本型 : Y=21.3xl**+1.5x2NS+7.3x3NS+0.18x4-91.7 5. 偏相關係數 및 寄與度 分析結果 統一系는 顯花數>穗數>粒重>登熟의 順으로 表示되었으나 日本型의 境遇에는 登熟>穗數>顯花數>粒重의 順으로서, 다른 分析結果와 달리 登熟의 收量에 對한 效果(直接效果)가 큰 傾向이었다. To compare of scientific reasonabilities of the high-yielding characters and broad adaptability between Tongil and Japonica cultivars in Honam district, the mode of response of yield components in the constitution of yield to N,P,K fertilization was determined by linear and quadratic regression equations, multiple regression equations, simple and multiple correlation coefficients, and partial correlation coefficients(path coefficients) and contribution ratio analysis, respectively. Datas for the analysis were collected from the annual reports of the rural developmental research institutes in Honam discrict(1970~1976). The results are summarized as follows: 1. According with N fertilization, the yields of both cultivars were linearly increased, through the increase of no. of panicles per hill and no. of spikelets per panicle(in Tongil cvs.) and no. of panicles per hill(in Japonica cvs.). With P and K, yield of both cultivars were increasing in quadratic responses. 2. Among fertilizers, nitrogen was most superior effect to make yield increments. And the higher yielding in Tongil cvs. than in Japonica was rather conducted from the differences in basic productive potentials than the fertilizer responses btw. two cultivars. 3. Simple correlation coefficient analysis showed significant correlation btw. yield and no. of spikelets per an area(in Tongil cvs.), and no. of panicles per hill(in Japonica cvs.). 4. Multiple regression analysis of the effect of yield components on the yield constitution indicated, in Tongil cvs.. inevitability of all of the components in explanation of yield response to fertilization. However, in Japonica cvs., indicated the effect of no. of panicles per hill only as follow. Tongil cvs.: Y=20.3xi**+3.9x2**+22.4x3**+3xt**-783.1 Japonica cvs: Y=21.3xl**+1.5x2NS+7.3x3NS+0.18x4-91.7 5. As results of partial correlation coefficients(path coefficients) btw. the yield and its each components, Tongil cvs. showed the closely related pattern with other analysis above, namely: No. of spikelets per panicle>No. of panicle per hill>Wt. of 1,000 grains>Grain maturity ratio in their order of contribution potentials(direct effect ratio) to the yield; However, Japonica cvs. showed the importance in direct contribution effects of the grain maturity ratio to the yield, to recognize such an order of contribution potentials, namely: Grain maturity ratio>No. of panicles per hill>No. of spikelets per panicle>Wt. of 1,000 grains.

DS-CDMA 의 용량개선을 위한 다중사용자 복조시스템

남옥우,김재형 창원대학교 정보통신연구소 2001 精報通信論文集 Vol.5 No.-

In this paper, we research the concepts and classes of Multi-User Detection Systems. MUD holds much promise for improving DS-CDMA performance and capacity. Multiple access interference significantly limits the performance and capacity of conventional DS-CDMA systems. In MUD, code and timing information of multiple users is jointly used to better detect each individual user. The optimum multi-user sequence detector is known, and provides huge gains in performance and capacity over the conventional detector ; it also minimizes the need for power control. Unfortunately, it is too complex to implement for practical DS-CDMA systems. Many simpler suboptimal MUD have been proposed in the last few years, all of which have the potential to provide substantial performance and capacity gains over the conventional detector. Most of the detectors fall into two categories : linear and subtractive interference cancellation.

The primary objective of this study was to make the prediction percentile tabulation of the sum of mesiodistal widths of the unerupted permanent canines and premolars derived from the sum of mesiodistal widths of the erupted permanent incisors in normal and crowding groups. Crowding group consisted of 85 pairs of dental casts (42 males and 43 females) with more than 4mm of crowding in anteriors. Normal group consisted of 109 pairs of dental casts (65 males and 44 females) with less than 1mm of spacing or crowding in anteriors. The mesiodistal crown diameters of permanent teeth were measured from the dental casts using the sliding calipers (Mitutoyo Co., Japan). From the study, the obtained results were as follows: There were not significant differences between male and female in both groups on the basis of the ratios between the sum of mesiodistal widths of incisors and the sum of mesiodistal widths of canines and premolars. There was not significant difference between two groups on the basis of the ratio between the sum of mesiodistal widths of mandibular incisors and the sum of mesiodistal widths of mandibular canines and premolars and was significant differences between two groups on the basis of the ratio between the sum of mesiodistal widths of mandibular incisors and the sum of mesiodistal widths of maxillary canines and premolars. There was significant difference between two groups on the basis of the ratio between the sum of mesiodistal widths of maxillary incisors and the sum of mesiodistal widths of mandibular canines and premolars. There was significant difference between two groups on the basis of the ratio between the sum of mesiodistal widths of maxillary incisors and the sum of mesiodistal widths of maxillary canines and premolars. The percentile prediction tabulations were made in an attempt to predict the sum of mesiodistal widths of the unerupted permanent canines and premolars derived from the sum of mesiodistal widths of the erupted permanent mandibular incisors in each group. The percentile prediction tabulations were made in an attempt to predict the sum of mesiodistal widths of the unerupted permanent canines and premolars derived from the sum of mesiodistal widths of the erupted permanent maxillary incisors in each group.

韓國에 있어서 失業과 인플레이션이 階層別 所得分配에 미친 影響

李在玉 慶一大學校 1990 論文集 Vol.6 No.1

In the present situation where there is an extremely high concern about income distribution, it would be a very significant work to analyze the effects of the change of many macroeconomic variables appearing as a result of the economic policy of government, concerning the size distribution of income. Among many macroeconomic variables having influence upon the size distribution of income, the following two channells of influence are especially important: -changes in the level of unemployment; -changes in the rate of inflation. Therefore, in this thesis, I tried to analyze the effects of major macroeconomic variables, that is, the change in unemployment and in inflation over the size distribution material and the Blinder Esaki model. Even though the materials used here are not completely reliable, the results of analyzing the maximum available materials seem to be indicating that the appearance of unemployment has a regressive effect on the size distribution of income. Though it is less firm than the estimated result of inflation, it can be assumed that the increase of the unemployment rate transferred income from the lowest 20% to the second 20% and to the top 20%. Like unemployment, the generation of inflation seems to have a regressive effect on the size distribution of income. It can also be estimated that each one percentage point rise in the inflation rate transferred 0.15% of the national income from the lowest 60% to the top 20%. Thus in Korea, both variables of unemployment and inflation generally were found to have a regressive effect in transferring income from the low income group to high income group. What especially draws our attention is that the poor group, which is the lowest 20%, suffers the biggest disadvantage from inflation as well as from unemployment. Therefore, in order to reduce income inequality, a positive government income support policy toward the lowest 20% is required.

The purpose of this research is to find out the level of understandings of professors, directors, and teachers about ecology centered early childhood education. This research is to outline the direction the ecology centered early childhood education should take. Below are the research problems that are dealt with in this research. First, what are the understandings of professors, directors, and teachers about the status of current ecology system? Second, what are the understandings of professors, directors, and teachers to the present early childhood education? Third, what are the understanding of professors, directors, and teachers about ecology centered early childhood education? Fourth, what are the ideas of professors, directors, and teachers about the preconditions and problems that arise when practicing the ecology centered early childhood education? The research targets used in this research are a total of 526 people ; 71 professors from the departments of Early Childhood Education and Child & Family Studies located in the Pusan, Ulsan, Kyung-nam areas and 88 directors and 367 teachers of both private and public kindergartes and child care centers. The research tool used for this research is a questionnaire asking the 'understandings of professors, directers and teachers about the ecology centered early childhood education' that has 48 questions including the forty cπle 5-ponts rating scale asking about each research target. The summaries of the important results of this research are listed below. First, for the understanding of the ecology system, all three research targets did not have the tendency for firmly favoring the ecology system. However, they recognize the crisis of environment and know why this crisis is occurring, Also, they have the understanding that to know why this crisis one has to know the limits of technology, the policy of the government has to be changed, and proper education has to be given. Second, to the understanding of the present early childhood education, there are some difference of understandings, but they recognized that the present early childhood education is not nature based but mostly technology based and they are not satisfied with the present system. This shows that they understand that the present technology oriented early childhood education has to be changed to the ecology early childhood education. Third, for this change to happen, new ecology centered early childhood education programs have to be made and applied, Also, the present early childhood education with the education system of promoting teachers and directors has to be changed to a whole new direction.

There is a lot of development in the part of architectural building technology today. In many high-rise buildings we can control the indoor space with artificial mechanical methods using fuel energy. It makes the crisis of the earth environments. Now, we must think about the ecological system and the sustainable development. Our ancestor had the wisdoms to use the nature, the sun and water energy circulations. To prevent the environmental pollution, we must team from the vernacular architecture. And the participation from a planning stage is a good method to extend building life.

세수추계방법에 관한 연구

이재옥,기석도 경일대학교 산업정보연구소 2000 産經硏究 Vol.7 No.1

정확한 세수추계는 예산편성 작업에만 필요할 뿐만 아니라, 여러 가지 세법개정안들이 제안될 때 이들 대안들을 평가하는 데 매우 중요하게 사용된다. 왜냐하면 세수추계가 정확하지 않으면, 예산안이 세입실적을 정확히 반영하지 못하므로 새롭게 조정해야할 필요가 있고, 또한 세법개정안에 대한 세수변화 효과를 올바르게 평가할 수 없으므로 사회적 손실이 크기 때문이다. 또한 정확한 세수추계는 조세정책을 수행하기 위한 기초자료로서도 매우 중요한 요소가 된다. 이에 따라 세수추계에 대한 관심이 매우 높아져 세수추계의 정확도를 높이기 위한 세수추계방법의 개발을 위한 노력은 계속되고 있다. 본 연구의 목적은 여러 가지 세수추계방법 대해 고찰해 봄으로써, 각 세수추계방법이 가지는 의의와 시사점을 제시하는 데 있다. 이를 위해 세수추계방법을 인과모형, 거시경제모형, 모의실험모형 등으로 나누어 고찰해 보았다. 또한 각 사수추계방법을 비교·분석함으로써, 이들이 지니는 시사점과 개선방향을 모색해 보았다. 분석결과, 각 세수추계방법들이 지니는 의의와 시사점은 매우 크다고 할 수 있으며, 앞으로 구체적인 세수추계모형을 통한 실증적 연구가 계속되어 보다 정확한 세수추계모형 개발이 이루어져야 할 것으로 보여진다.

김재훈,백억종 한국해양대학교 산업기술연구소 2003 연구논문집 Vol.20 No.-

본 논문에서는 한국어 문서에 포함된 수식표현의 인식 방법에 대해서 기술한다. 수식표현 인식은 부분 구문분석의 한 부분이며 정보추출 시스템과 질의응답 시스템 등에 사용될 수 있으며, 이들의 공통적인 특징은 신속하고 정확해야 한다는 것이다. 본 논문에서는 이를 위해서 Unix^TM 도구인 lex를 사용한다. 본 논문의 시스템을 평가하기 위해서 자체 개발된 신문 말뭉치를 사용하였으며, 이 말뭉치에서 재현율은 90.8%이고 정확률은 86.9%이다. 다른 여러 실험을 통해서 본 시스템은 정확하고 신속하게 처리되고 있음을 알 수 있었다. In this paper, we describe the recognization of Korean numerical expressions as a part of partial parsing from text. Numerical expressions can be used in several systems such as information extraction systems and question-answering systems. One of desired characteristics of these systems is the fastness. To achieve this goal, we use lex. a Unix ^TM tool, that is an implementation of finite-state automata. To evaluate our system, we used a newspaper collection. We achieved the recall of 90.8%, and the precision of 86.69%. We observed that the system is fast and correct through several experiments.
