김진형 단국대학교 2000 論文集 Vol.35 No.-
The rapid growth in the Korean Economy over the last three decades has brought with it important changes in the country's energy sector. Not only has the amount of energy consumed by Korea increased significantly, but there have also been important structural changes in the way that energy is consumed. During the period 1990 to 1998, the average annual growth rate of energy consumption was higher than that of our economy, which means our economy is significantly more energy intensive than before. The purpose of this paper is to estimate the price and income elasticities of energy demand and test empirically for the changes in energy consumption pattern. Using the conventional log-linear model, price and income elasticities for total energy and three individual energy sources: oil, coal and electricity, were estimated separately for the three sample periods, the 70's, 80's and 90's. The comparison of the elasticities among the periods confirms that energy consumption pattern has been significantly changed for the last thirty years. The estimation results show that, in the 80's, energy consumption was highly sensitive to price changes, but low sensitive to income changes. However, when it come to the 90's, the demand for energy is extremely price-inelastic in respect to oil and coal, and highly income-elastic in the case of oil. The inelastic response of energy demand implies insensitive consumer response to higher energy prices and a protracted adverse impact on output, inflation, balance of payment and other macroeconomic variables. This significant change in consumption behavior throw light on some important policy issues and provide guidelines for policy-makers. In Korea, increase in petroleum prices are translated into increase in the cost of both industrial and agricultural output and, potentially, into a reduction of cost competitiveness in the international market. The insensitive price elasticities also limit the feasibility of dampening petroleum demand through pric-induced effects. This calls for active supplementary use of non-price instruments to encourage conservation. In addition, the highly sensitive response of energy demand to the change in come suggests that efforts to enhance oil emergency preparedness should be continued, included increasing emergency stockpiles and refining the procedures dealing with demand restraint measures.

The LNG industry is highly capitalistic. The total investment required for a new export project of 6 to 8 billion m' /year is about 5 billion dollars and may be as high as 10 billion dollars. Hence the promoters of such projects demand guarantees, to ensure the financial profitability of the project. This has led the different partners to sign long-term contrcts (20 to 25 years), to insert rigid take or pay clauses, assigning the volume risk to the buyer, and to the determination of a price throughout the duration of the project to insure its profitability. The determination of a base price is the first factor to guarantee this profitablity. This price is determined either on an FOB basis or on a CIF basis or ex-ship (delivered, before regasification). In the first LNG contrcts signed before the first oil crisis, a fixed CIF price had been determined. The oil crisis made the fluctuations in the base price inevitable as a function of the energy market. The indexing of the base price to representative prices of the energy market became the rule. This indexing is subject to periodic renegotiation. The implementation of the indexing of the base price according to the market has assumed different forms in the contracts. Contrary to the oil market, no world price exits for natural gas. The distances, the configuration of the markets, the competing energy system, tax distortions and environmental constraints are all distinctive factor. Thus three major regional markets can be distinguished, with their prices and their indexing methods :Japan, Europe and the United States. Whereas, in the 1970's the indxing terms of the base price referred to the prices of petroleum products on the European market and to the posted price of crude oils on the Japanese market, since the second oil crisis, indexing to the price of crude has become the rule. This study presents a detailed discussion on the trend in the determination of the LNG contract prices and provides a comparion of indexing methods among contracts signed by three Asian importing countries : Japan, Korea and Taiwan.

According to The Body Fat Norms of Getchell.B., it is that 68 high-school students of 15-19 ages are divided into the six groups. The purpose of this study is to determine weight, height and serum zinc level in each group. 1. The body weight of E.F Groups is higher than that of A.B.C.D Groups significantly.(p<0.001) 2. As the height of E Group is higher than any other group by 178.19±7.43 cm, there is no difference significantly. 3. As the serum zinc level in each group is not different significantly. E Group is the highest by 109.83±17.77ug/dl and C Group is the lowest by 95.29±24.35 ug/dl.

The purpose of this study is to compare body composition especially %fat, Lean Body Mass and serum zinc concentration among differently trained athletes. Thirty-six high school male students participated in this study. Among participants, 14 were anaerobic trained group (weighter lifter), 6 were aerobic trained group (distance runner) and 16 were age matched control group. No significant difference of %fat was founded among groups. Lean body mass (LBM) of anaerobic group was significantly higher than aerobic and control group. Serum zinc level of control group was significantly lower than other groups. But there was no difference of serum zinc level between anaerobic and aerobic group. Conclusion of the study are as follows. Anaerobic and resistant-oriented exercise enhancing muscle mass. Also regardless of different exercise intensity and chronic exercise higher serum Zinc concentration was found in athletes than non-athletes. Further study needs to elucidate the exact mechanism of zinc metabolism related to other athletic events and variables.
