Logit分析에 의한 比較優位의 實證硏究 : 1970년대 한국 제조업을 중심으로 The Case of Korea's Manufactures in 1970s

蔣鳳圭,兪日善 慶尙大學校 1988 論文集 Vol.27 No.2

Since L eontief(1954) tested empirically the Heckscher-Ohlin theorem, the general conclusion which emerged from the subsequent glut of researcu is to discard simple, two factor(capital, labor) trade theories in favor of muti-factor(capital.labor) trade theories in favor fo multi-factor trade model. It is summed up as Heckscher-Ohlin-Vanek equation AT=V-sVw. This equation, which consists of three variable-trade(T), factor intensity matrix(A), relative abundance (V-sVw),provides the theoretical base for the empirical test. As for the method of empirical test. I used the dependent variables as a binary variable set at unit if NX(net exprot) >0 and at zero if Nx<0.It should be noted that logit analysis which is based upon the model in which the probability of dependent variables being of a particular sign is related to a list of explanatory variables, show that comparative advantage and its determinants explain only the direction , not quantity, of trade. The model is tested in various forms with different definitions of factor intensity . According to the results of logit analysis. It is found tha the Korean manufactured industry in 1970's had a comparative advantage in relatively unskilled labor intensive commodity, but had limitedly a comparative advantage in human caspital in the end of 1970s. We also could recognize the relatively disadvantageous effect of the physical Captial and nature on trade in the same period. We are not sure that there existed the change of the indusrial structure in the 1970s.

Melt spinning process was used to prepare the rapidly solidified ribbons of Mg-6Zn-5Ca(wt%) alloys with 1, 2 wt% Si. In present work, SEM, EDS, XRD, and microhardness test were performed to investigate the characteristics of the ribbons. The microhardness of the ribbons according to Si content decreased slowly since the content of MgCaSi precipitates in air side of ribbons increased. The Mg-6Zn-5Ca-1Si melt-spin ribbon heat-treated at 150 ℃ and 1hr showed the maximum microhardness and then its microhardness decreased slowly above 150 ℃.For the ribbon of alloy with 2 wt% Si, its hardness increased up to 200℃ and then decreased rapidly. As the content of Si and the heat-treatment temperature increased, the content of MgCaSi formed initially in air side increased. The present result showed that the addition of Si to Mg-6Zn-5Ca alloys decreased the microhardness of the ribbons and did not improve them mechanically even after aging.

동사적 합성어에 대해서

이봉선 全北大學校 語學硏究所 1987 어학 Vol.14 No.-

지금까지, 필자는 동사적 합성어의 과생산을 막고, 어구에 불필요한 복잡함을 주지 않으면서도 가능한 단어를 예언할 수 있는 가장 합당한 이론이 어느 것인가를 보이려고 노력했다. 맨 먼저 작업으로써 동사적 합성어도 어근 합성어와 같은 방법으로 생성된다는 것을 주장하고, 합성법으로써 Allen(1978)의 방법을 받아들였다. 그러나 이 합성법은 무수한 합성어를 생성할 수 있다. 그땐, 그 합성어가 가능한 단어인지 불가능한 단어인지를 구별할 문제에 직면하게 된다. 필자는 가능한 합성어를 예언하고 불가능한 합성어를 제외시킬 이론적 방법으로 lieber(1983)의 논항 연결원칙을 취했다. 어휘항목들은 동사적 합성어를 구성할 때 이미 그 자체 속에 만족되어야 할 어휘 논항구조를 갖고 있기 때문에 논항 연결원칙은 오직 논항이 연결되는 것만 봄으로써, 우리는 영어에서 찾아지는 여러 동사적 합성어를 잘 설명할 수 있었다. 또, 이러한 이론적 틀에 근거해서, F-S원칙의 문제점, 그리고 Selkirk(1982)의 이론의 문제점도 살펴보았다. 그 결과, Lieber(1983)의 이론이 우수하다는 것을 보였다. 그러나 Lieber의 이론도 어느 경우, 즉 tree eating of pasta에서는 설명할 수 없는 난관에 봉착하기도 한다(4장 참조). 이때 만약 통사에서와 같이 접사의 영역(scope)을 고려하면, Lieber가 제시함 방법이 모든 동사적 현상을 잘 설명한다.

光陵의 전나무 生長의 定量的 分析에 관한 硏究

朴奉奎,崔炳善 梨花女子大學校 韓國生活科學硏究院 1980 韓國生活科學硏究院 論叢 Vol.25 No.-

光陵의 전나무 생장의 정량적 분석 결과는 다음과 같다. 즉, 1) Logistic equation은 곡선이 생장 초기와 생산량의 극한치에 가까운 값들에서 오차가 비교적 크게 나타났기 때문에 측정치에 적합한 생장식이라고 볼 수는 없었으나 최대 생산적 시기를 나타내는 변곡점(inflection point)이 거의 일치하였으므로, 최대 생산력 시기를 구하기 위해서는 Logistic equation을 쓰는게 바람직하다고 볼 수 있었다. 2) 측정치와 3개의 생장식의 이론치와의 비교에서 Gompertz equation에 의한 이론치가 가장 근사한 값을 나타내어 본 연구에서 조사된 전나무의 생장식으로 적합하였으나 최대 생산력시기가 측정치보다 일찍 나타났으므로 최대 생산력시기의 조사를 위해서는 적합하지 않았다. 3) Von Bertalanffy equation의 이론치는 측정치보다 생장이 느리게 나타났고, 최대 생산력시기도 Gompertz equation 보다도 일찍 나타나므로 본 연구에서 조사된 전나무의 생장식으로는 적합치 않다고 볼 수 있었으나 W∞의 값 즉, Logistic 이나 Gompertz equation에서는 계산에 의하여 구할 수 없는 생산량의 극한값을 구하기 우해서는 필히 이 식을 유도 해내는 고정을 도입해야 구해 낼 수 있었다. Quentitative analysis was made to estimate the product of Abies holophylla in Kwangnung forest. The width of annual rings was measured to obtain the overall yearly growth. The growth curve was S-shaped, that had an upper asymptote, so to speak, carrying capacity, and that approached this asymptote smoothy, not abruptly. Three types of sigmoid growth curve-Logistic, Gompertz, and Von Bertalanffy growth equation-was analyzed with and without Rivklefs' technique, by which conversion factors were used. As a result, caluculated maximum growing time by the Logistic equation wals 15-17 years which was comparatively fit in comparison with data obtained by survey. Calculated annua products by the Gompertz equation were fittest among three equations. Asymptote was calculated by Von Bertalanffy equation.

체계적인 위험예측을 통한 사업타당성 모델 분석

Pre-design phase becomes very important because the construction market in Korea is often unpredictable. Also, the construction market is diversely changing because social environmental factors are rapidly transforming. Therefore, construction projects are becoming complex and diverse. Furthermore, the risk being ingerent in construction projects are increasing, and now people are considering about the risk management of construction projects in successfully handling the risk factor. So, most risky period construction project is a feasibility analysis phase where the possibility is highest. But the existing feasibility analyse cannot fulfill their functions very well in construction projects because they .are based on the intuitive approach rather than the systematic approach. Therefore, the objective of this research is to propose an another feasibility analysis method reflecting a risk prediction model through an analysis of the existing studies and a case study.

This study was to identify the factors affecting the obesity as body mass index by sex, age, lifestyle and health behavior. The subjects for this study were all adult in Choongnam-do and capital region, Korea. The data were collected in November, 2007. The results of this study are as follows. Body mass index (BMI) by sex showed that significantly higher in the male group (23.04±3.5) than in the female group (21.12±2.7) (p<0.01). BMI by age showed that significantly increased according to older group (p<0.01). BMI by exercise showed that significantly higher in does not the exercise group than in the exercise group for male group (p<0.05). BMI by kind of exercise showed that significantly higher in ball game exercise group than in aerobic exercise group for female group (p<0.05). BMI by meal frequency per day showed that significantly higher in 3 times and more group than the 2 times and below group for female group (p<0.05). BMI by speed of eating showed that significantly higher in fast group than the slow group for male group (p<0.05). Generally, a person who drink show that higher BMI. BMI showed that significantly higher in parents is obesity group than the normal parents group (p<0.05).

1) 각 숲의 토양 조성은 비교적 유사하였으나 주변 식생은 23종이 공동 출현하엿고, 94종이 단독 출현하여 차이를 보였다. 2) 잎갈나무숲은 수령이 대체로 15~40년 정도가 많았으며, 잣나무숲은 수령이 대체로 35~60년 정도가 많았다. 3) 두 종의 생각곡선은 S字形의 logistic 곡선을 이루고, 이는 Robertson(1907)의 생장식에 적용시킬 수 있었다. 4) 두 종의 최대생장기는 11~13년으로 비슷하엿으나 잣나무가 느린 성장을 이루었다. 5) 두 종의 최대치벌시기는 잎갈나무가 17년 정도이고, 이때의 흉고 주위는 57cm정도이며, 잣나무는 19년 정도이고 이때의 흉고 주위는 53cm정도이다. Larix olgensis and Pinus koraiensis forests in kwangnung were investigated from July through August 1978. In order to Analysis Microevironmental factors, the three layers of forest-tress, shrubs and herb layer, and soil were observed and analyzed. Quantitative and dimension analysis was used to estimate product and productivity for two species at certain times during the year. the growth curve is sigmoid, or S-shaped. theS-shaped curve has an asymptote, and we can use Robertson's growth formula. As s result, estimated maximum productivity time of larix olgensis is 11 years, and pinus koraiensis is 12 years. Maximum cutting time of Larix olgensis is 17 years, Pinus koraiensis is 19 years.
