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.

정문현,심재훈,조덕영 釜山 大學校 經營 經濟 硏究所 2002 經營 經濟 硏究 Vol.21 No.1

본 연구는 보다 정확한 조세혜택의 크기를 측정하고 동 조세혜택에 영향을 미치는 결정 요인이 무엇인지에 대하여 실증적으로 검증하였다. 1999년부터 2001년까지 금융감독원의 전자공시 자료를 이용하여 금융·보험·증권업종을 제외한 기업을 대상으로 분석을 실시하였다, 검증결과 첫째, 대차대조표 및 손익계산서의 자료를 근거로 조세혜택의 추정치(TSf)와 실제납세자료를 이용한 조세혜택의 측정치(TSr)는 유의적으로 차이가 났으며, 이는 조사혜택을 근거로 한 선행연구들의 여러 가설들의 신뢰성에 문제가 있음을 의미하고 있다. 둘째, 조세정책상 세법에 의한 조세혜택에 영향을 주는 기업규모, 부채비율, 투자지원도 등의 기업특성변수는 기대부호와는 전부 일치하며, 대부분 유의적인 값을 보여 ①중소기업일수록, ② 부채비율이 높을수록, ③투자지원도가 높을수록 조세혜택을 많이 받는 것으로 나타났다.

특별소비과세가 부가가치세 및 가계소득ㆍ소비지출에 미치는 영향분석 : 가전제품 등 생필품 항목을 중심으로 Inhome Appliance and Essential Goods Item

鄭文鉉,曺德永 釜山大學校 經營 經濟 硏究所 1999 經營 經濟 硏究 Vol.18 No.2

소비재물품 등의 소비를 억제하고 세제면에서 실질적인 조세부담의 형평을 기하기 위하여 도입된 특별소비세가 경제적 여건의 변화와 국민소득의향상 등으로 인해 여러 차례의 개정이 있었으나, 경제적·사회적 환경의 변화로 인해 현재는 호화사치성 품목이 아닌 소비가 대중화된 생필품목들이 상당수 포함되어 있어, 동 세제 도입의 목적을 달성하고 있지 못하는 것으로 나타나고 있다. 본 연구에서는 특별소비세가 부가가치세 과세표준에 포함됨으로 인한 부가가치세 부담은 어느 정도이며, 생필품과 관련된 품목에 대한 특별소비세 및 부가가치세 부담이 각 소득계층의 소비지출에 미치는 부담이 어느 정도인지 분석하였다. 분석결과 특별소비세가 부가가치세 과세표준에 포함될 경우 2종은 약 13.7%, 3종은 13%만큼 그 부담이 증가하였고, 최소 유통단계마저 고려하면 각각 28.5%와 27.8%로 높은 상승을 나타내고 있다. 그리고 특별소비세로 인한 소득계층별 소비지출부담은 특별소비세를 부과하지 않는 경우에 비해 2종인 가전제품류에 대해서는 구입가격에 대해 약 13.7%, 3종은 13%를 더 부담하고 있는 것으로 나타났다. 또한 특별소비세가 부가가치세 과세표준에 포함됨으로 인한 소득계층별 부가가치세 부담은 최하 소득계층인 I분위가 소득대비 약 8.8%를 부담하고 있는 반면, 최상소득 계층인 V분위는 약 4.6%를 부담하고 있어 조세부담의 역진성 보완과 조세부담의 형평유지를 위한 도입목적이 상실되고 있음을 보여준다. 따라서, 조세부담의 역진성과 조세부담의 형평유지를 조금이나마 달성하기 위해서는 현행 특별소비세 중 주요 생필품과 서민대상의 품목이라고 판단되는 물품에 대해서는 특별소비세 부과대상에서 제외시켜야 할 것이며, 이로 인한 세수 감소분은 새로운 부과품목의 추가와 대체세수의 개발로 보완하여야 할 것이다.

Aminoaluminum Hydride에 의한 카르복시산 에스테르류의 환원반응

정덕상 濟州大學校 師範大學 科學敎育硏究所 1985 科學敎育 Vol.2 No.-

A method for the preparation of aldehydes from esters of carboxylic acids by use of diaminoaluminum hydrides such as bis (4 - methyl 1 - piperazinyl) aluminum hydride (BMPA) dimorpholionaluminum hydride (DMA) and dipiperidionaluminum hydride (DPA) was described. It was found that BMPA, DMA and DPA reduce esters of carboxylic acids of aldehydes in good yield very smoothly without accompanying alcohols.

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

다중 가설 추적 알고리듬의 성능 평가

정영헌,한찬호,최덕규 경운대학교 산업기술연구소 2001 産業技術硏究論文誌 Vol.3 No.2(C)

The Multiple Hypotheses Tracking (MHT) algorithm has been shown to be one of the most cost- effective estimation schemes for hybrid systems. Its performance, however, could only evaluated via expensive Monte-Carlo simulations. An effective hybrid approach to the performance evaluation without recourse to simulations is presented here. This approach is based on a scenario-conditional performance measure of hybrid nature in the sense that it is a continuous-valued function of a discrete-valued random sequence. The performance measure is calculated efficiently in an off-line recursion.

鄭永化,趙德鳳,崔春淳,馬相朝 광주보건대학 1984 論文集 Vol.9 No.-

To develop a beverage indigenous to Korea, Extracts from the mushroom were investigated for their chemical composition, extraction conditions and processing methods. Mushroom, Lentinus edodes which had been dried at 50℃ for 20 hours were extracted with hot water for 5 minutes, respectively. Fructose(10%, w/w) and licorice extracts(4 %, v/v) were added in the extracts. In an attemt to evalluate the quality of food by sensory testing, the difference testing for samples was conducted by selected members of a sensory panel. The results of the present study were as follows: 1. Amino acids of the final products were mostly composed of threonine and prolamine, glutamic acid, arginine, alanine, phenylalanine, etc. 2. GMP content of the final products was 2.09%(w/v). 3. It was concluded that extracts from the mushroom processes sufficiently acceptable qualities as a favorite beverage.

Cu(Ⅱ)이온과 Poly(vinyl alcohol)간에 생성되는 고분자-금속 착물의 열역학적 거동에 관한 연구

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

The dissociation constants for poly(vinyl alcohol) (PVA) at a constant ionic strength of μ=0.1(KCl) were measured by potentiometric titration at various temperatures. The formation constants for the Cu(II)-PVA complex at the same condition were also measured in this study. From the temperature dependence of those dissociation and formation constants, various thermodynamic parameters such as ΔG, ΔH, ΔS were determined. From the thermodynamic parameters, it was concluded that the dissociation of a proton from PVA is unfavorable with a negative entropy and positive enthalpy. In contrast, the complex formation was a spontaneous and exothermic process with favorable entropy.
