This study was carried out to investigate the current nutritional problems owing to the increased consumption of westernized food in Korea and also was conducted to compare the nutritional characteristics of Korean traditional meal with those of the Western diet in similar serving size. The results obtained from nutritional evaluation are as follows: 1. The percentage of calories represented by carbohydrate: lipid: protein was 65:15:20 respectively for Korean traditional meal (Table setting of 3 Chop) therefore these ratios meet the dietary recommended allowances for Koreans. 2. Nutrient values of Korean traditional 3-Chop were shown to be better balanced than those of Western diet when the nutrients of the two types of diet were estimated by similar serving sizes and calories. 3. Compared to the Korean traditional meal, most fast foods were nutritionally imbalanced especially in that most of them showed higher amounts of fats. These results show that Korean traditional meals supply ideal nutrient intakes in contrasts to the westernized diet, therefore much work remains in developing a variety of menus and standard recipes for Korean traditional meals according to the changes in diet trends as well as emphasing the importance of Korean traditional meals as part of an ideal, well-banlanced diet.

Lanthanide(III) and mercury(II) complexes of the 18-membered hexaaza Schiff base macrocycle 2,11,17,26,31,32-hexaazapentacyclo[26,2.1.1??,O??,O??] dotriaconta-1(31), 2,4,6,8,10,12,14,16(32) ,17,19,21,23,25,27,29-hexadecane([18]HAM) ahve been synthesized by the metal template condensationof phthalic dicarboxaldehyde and 2,6-diaminopyridine. Discrete mononuclear complexes [Pr([18]HAM)(NO₃)(OH)]NO₃·2H₂O,[Sm([18]HAM)(NO₃)(H₂O)(OH)]NO₃·2H₂O, [Gd([18]HAM)(NO₃)(H₂O)(OH)]NO₃·3H₂O, [Dy([18])HAM)(NO₃)₂(H₂O)₂]NO₃·2H₂O, and [Hg([18])HAM)(H₂O)₂(ClO₄)]ClO₄· ?H₂O, have been synthesized by using the respective hydrated lanthanide(Ⅲ) nitrate and mercury(Ⅱ) perchlorate as the template. The lanthanide(Ⅲ)-marcrocyclic complexes (lanthanide(Ⅲ)-[18]HAM) was decomposed by c-HClO? forming [18] HAM and liberating the lanthanide(Ⅲ) ion. Co(Ⅱ)- Ni(Ⅱ)-Cu(Ⅱ)-complexes of acyclic, potentially tridentate compartmental Schiff bases ([9]acy) complexes containing d-metal ion Co(Ⅱ), Ni(Ⅱ), and Cu(Ⅱ) ion have been prepared by using metal template condensation of phthalic dicarboxaldehytde and 2,6-diaminopyridine. The complexes and macrocycle were characterized by elemental analysis, fast atom bombardment mass spectrometry, infrared spectroscopy, and molar conductivity. The template potential of the lanthanide(Ⅲ) cations of various sites in the assembly of [18]HAM is due to the flexibility of the macrocycle to adapt to the geometrical requirements of the metal ions and to the steric demands of the exocyclic ligands

본 연구는 조세부담의 수평적 공평성변동계수와 잔차변동계수를 이용하여 법인세부담의 집단간 공평성을 실증적으로 검증하였다. 1996년부터 1999년까지 우리 나라 증권 거래소에서 상장된 기업 중 자본구조가 현격히 다른 금융·보험·증권업종을 제외한 기업을 대상으로 5개의 집단으로 구분하여 변동계수와 잔차변동계수를 이용하여 분석을 실시하였다. 검증결과 첫째, 조세부담률은 각 집단별로 큰 차이를 보이지 않았으나, 1집단이 다른 집단에 비해서 보다 많은 조세를 부담하는 것으로 나타나 수직적 공평성 문제가 존재하고 있음을 간접적으로 증명하고 있었다. 둘째, 법인세만을 고려한 경우 변동계수와 잔차변동계수에서 모두 법인세 차감전 이익의 크기가 낮은 집단일수록 수평적 불공평성이 존재하는 것으로 나타났다. 셋째, 변동계수와 잔차변동계수의 변동률은 서로 상반된 결과를 제시하고 있는데, 변동계수의 변동률은 연도간의 차이가 거의 발생하지 않는 것으로 나타났고, 조세부담능력이 낮은 집단일수록 수평적 공평성이 향상되는 추세를 보였다. 하지만 잔차변동계수의 변동률은 집단별로 각 연도간의 큰 차이가 발생하지는 않았으나 가중평균변동계수의 변동률을 고려하면 오히려 수평적 공평성이 감소되는 추세를 보였다.

세의 기본이념은 「공평」,「간소」,「국제조화」에 있으며, 세제가 준거해야만 하는 일반적 기준은「조세원칙」이라고 말하여진다. 유명한 것은 아담 스미스의 4원칙으로 「공평, 명확, 편의, 최소징세비」에 부합되는 제도이어야 한다고 언급하고 있다. 2000년 6월말 현재 우리 나라의 자동차 대수는 약1,073만대로 국민 4명당 1대 정도로 대중화, 보편화되고 있어, 이제는 소형 이하의 차량에 대해서는 거의 생활 필수품이라고 하여도 무방할 것으로 인식되는 시대에 살고 있다. 그럼에도 불구하고 자가용자동차(특히 승용차)에 관련된 각종 세금의 현황을 살펴보면, 자동차는 일종의 사치품이라는 과거 70~80년대의 인식에서 아직도 벗어나지 못하고 있는 것 같으며, 자동차와 관련한 세금은 무려 12종이나 되고 이도 취득, 보유, 이용단계별로 세금을 부과하고 있어 과세의 형평성 등 많은 문제를 안고 있다. 한편, 일본의 경우, 자동차 대수는 약 7,000만대로 국민 2명당 1대의 정도이며, 도로정비계획이 변경될 때마다 새로운 세의 도입이나 세의 증액이 반복 되풀이 되어온 결과, 현재는 약 10종의 세금이 부과되고 있고, 이도 우리 나라와 마찬가지로 취득, 보유, 이용단계별로 세금을 부과하고 있으며, 이들 세금이 중복적이고, 세 부담이 너무 과중하여 그 근본적인 대책마련이 제기되고 있다. 따라서 본 논문에서는 우리 나라와 일본의 자동차 관련 세 및 문제점에 대해 살펴보고, 일본의 자동차 관련세에 대한 개혁방안을 살펴봄으로써 향후 우리 나라의 자동차 관련 세가 나아갈 방향에 대해 도움이 되고자 한다.

GC 및 GC-MS를 이용한 Houttuynia cordata와 Saururus chinensis의 휘발성 성분의 비교

鄭悳商 제주대학교 1991 논문집 Vol.33 No.-

본 연구는 한국에서 자생하는 2종의 삼백초과 식물들의 휘발성 성분을 비교하기 위하여 수행되었으며, 그 결과를 요약하면 다음과 같다. 한국산 삼백초의 휘발성 성분을 처음으로 분리하여 확인한 결과, C??H??인 이성질체 화합물들이 주종을 이루었으며, 약모밀(한국산 및 일본산에서 도)-에서는 검출되지 않았던 benzodioxole 계통 의 Safrole(M.W. : 162)이 확인되었다. The volatile constituents in Sururus chinensis, growing in Korea, were isolated and identified by gas chromatography using glass capillary columns(OV-1, PEG-20M and SE-54) and GC-Mass spectrometry. The volatile constituents of Saururus chinensis were very diffent from those of Houttuynia cordata, that is, the former was mainly composed of sesquiterpenoids, while the latter monoterpenoids.

We have examined the relaxational response of the Ginkgo Folium water extract on isolated thoracic aorta from sprague dawley rat (300~350g) in the presence and absence of endothelium and the vasodilator nitric oxide. Segments of thoracic aorta obtained from rats immediately after delivery were mounted in organ baths superfused on a polygraph. We found that the thoracic aorta segments responded to the Ginkgo Folium water extract with a dose-dependent vasorelaxation. At 2.0 ㎎/㎖ Ginkgo Folium water extract, the relaxational response with and without endothelium were 75.8% and 6.9% of the maximum KCI-response. The Phenylepinephrine and 5-hydroxytrptamine - induced contraction at 10^-4M were inhibited by 77.3% and 75.8% after addition(2.0 ㎎/㎖) of the Ginkgo Folium water extract. After pre-treatment of the thoracic aorta with N^G-monomethyl-L-arginine(10^-4M), the vessels contracted in response to the nitric oxide synthase inhibitor. The present results show that nitric oxide may act as a crucial signal in the vasodilative action. In conclusion, Ginkgo Folium water extract-induced relaxation in the isolated rat thoracic aorta was composed of endothelium-dependent and dose-dependent relaxation. Endothelium-dependent relaxation may be mediated by release of endothelium derived relaxing factor, nitric oxide.

The study aims to identify the difference in the effect of the learner's observation ability improvement presuming the qualified companion's feed back. The subject of the study was 77 male student not having experience of kicking up with the horizontalbar which is the theme of the study among 99 students in the regular gymnastics classes of D and K universities. 77 subjects were grouped to be the controlled group of 40 and the test group of 37. The study compares and analyzes the data from the post test based on the pre test data making as the baseline data. the data collected was went through the t-test with SPSS/PC +9.0 version, the lower program for personal computer and the significance level was set to p<.05. the results of the pre and post test onthe kicking up assignment performance and when compares the detection ability after the practicing of the visual observational training, it shows much significant difference between two groups (p<.001). when compared the pre test (11.63±2.96) of the controlled to the post test (14.03±3.60) of the controlled, became to be t=-6.283 and showed statistically significant, which considered to be the results of those from that the instructors verbal feed back in the assignment performance per steps in every classof the kicking up assignment and from that the detection ability could be improved between the companions by comparing mutual attitudes and from the efforts of the learner himself to train till the end of the class. By these results one can find that the detect error rating is with high difference at the post test rather that at the pre test in both of the controlled group and the test group. Especially, the test group of its post test mean is with remarkably high detect error rating than the controlled group.

Pd(Ⅱ)이온과 Linear Poly(ethyleneimine)간에 생성되는 고분자-금속 착물의 구조와 성질에 관한 연구

한정호, 전은덕, 조태섭 영남대학교 기초과학연구소 2000 基礎科學硏究 Vol.20 No.-

Pd(II) metal ion has attracted interest of many researchers because of its potential applications and of its similarity and difference in chemical properties. In this study, complex formation of Pd(II) metal ion with polymeric amine ligand namely, linear poly(ethyleneimine)(LPEI), was investigated utilizing spectroscopic and potentiometric methods as well as elementary analysis. From UV/VIS spectroscopic study, complexation of LEPI to Pd(II) ion exhibit an absorption band at 347nm at the low mole ratio (below 2.0). This species can be understood either as the binuclear complex bridged by chloride ions or a complex of Pd(II) ion with three chloride ions and an amine group. At the high mixing ratio, absorption spectrum centered at 300nm was apparent, which is due to the complexation of LPEI to the Pd(II) ion. Mole ratio analysis for the LPEI-Pd(II) system revealed that complex formation was most stable at the LPEI ratio of 4.0 relative to metal ion. This result was confirmed by elementary analysis. From the potentiometric titration, successive and overall stability constants were measured and the results were analyzed by a modified Bjerrum method.
