In order to identify the sugars of saponin originated from Korean ginseng, experimentations were made on the four kinds of ginseng. The results are summarized as follows. 1. The starch content of Ginseng-tail, White-ginseng 3 and 6 years old-whole ginseng were 10.4, 31.5, 8.2, 25.6% and total sugar of its were 37.0, 61.5, 64.5, 62.5% and free sugar were 7.6, 10.5, 11.3, and 10.7% respectively. 2. Saponins were separated from Ginseng-tail, White-ginseng, 3 and 6 years old-whole ginseng by modified SHIBATA method. looms of crude saponin was used for the Thin layer Chromatography (TLC) and thirteen to twelve spots of saponin were isolated by double development $(Solvent:\;CHCL_3\;:\;MeOH\;:\;H_2O=65\;:\;35\;:\;10)$ and by two dimensional development. $(Solvent:\;nBuOH\;:\;HOAC\;:\;H_2O=4\;:\;1\;:\;5)$ The Pattern of spot was not significantly different according to Ginseng sample. 3. Glucose was identified from the acid-hydrolyzate of Ginsen-tail saponin by paper chromatography and isolated the unknown chromatogram seems to be pentose.

Changes in proximate composition, amino acid, free sugar, reducing sugar and vitamin contents of Curcuma longa L. (autumn woolgeom in Korean) and Curcuma atomatica Salib (spring woolgeom) were investigated according to picking time. Moisture, crude ash, crude protein and crude lipid were increased and non nitrogen substances was decreased by extending the picking time. Contents and ratio of total amino acid to essential amino acids was increased by extending the picking time. Free amino acid was increased by extending the picking time. Ratio of essential amino acids to total amino acids was decreased. Fructose was gradually increased, and then glucose, sucrose and total free sugars were decreased by extending the picking time. Amino acid and sugar contents of Curcuma longa. L. were higher than those of Curcuma atomatica Salib. In contents of vitamin C and $B_1$, Curcuma longa L. was decreased and Curcuma atomatica Salib was increased by extending the picking time.

Yam(Dioscorea) tubers were used as one of the dietary starches in Korea, China and Japan because of its characteristic properties. Yam tubers were powdered after freeze drying the sliced tubers to investigate carbohydrates. Chemical properties such as proximate components and carbohydrates were studied using three varieties of Korean yams, namely. D. batatas, D. aimadoimo and D. japonica. The proximate components of yam tubers showed that the major components of Korean yam tubers were carbohydrates and moisture. The main components of free sugars in yams were identified as fructose, glucose, sucrose and maltose. In addition to these four sugars, there were two unidentifiable peaks whose areas are too big to ignore. These results were obviously different from other reported data of free sugars in yams. The main components of total sugars were mannose and glucose.

Seojangdaeyajodo is a drawing of military night training on February 12th (lunar leap month), 1795. Focusing on the Seojangdaeyajodo, the characteristics and of the costumes worn by various types of officials were examined. There were 34 officials located near King Jeongjo in and around Seojangdae, with 27 Dangsanggwan and 7 Danghagwan. They wore three types of costumes, including armor, yungbok, and military uniforms. All of the twelve armor wearers and the five officials wearing yungbok were dangsanggwan, and the military uniform wearers included eleven dangsanggwan and six danghagwan. For the shape of the armor, the armor relics of General Yeoban, suitable for riding horses, and the armor painting of Muyedobotongji were referenced, and the composition of the armor was based on practicality. The armor consists of a helmet, a suit of armor, a neck guard, armpit guards, arm guards, and a crotch guard. The color of the armor was red and green, which are the most frequently used colors in Seojangdaeyajodo. The composition of yungbok was jurip, navy cheollik, red gwangdahoe, socks made of leather, and suhwaja. The composition of the military uniform was a lined jeolrip, dongdari, jeonbok, yodae, jeondae, and suhwaja. There were differences in the fabrics used in dangsanggwan and danghagwan military uniforms. Dangsanggwan used fabric with depictions of clouds and jewels, and danghagwan used unpatterned fabric. Moreover, jade, gold, and silver were used for detailed ornamental materials in dangsanggwan. The weapons included bows and a bow case, a sword, a rattan stick, wrist straps, and a ggakji. In the records of the King Jeongjo period, various colored heopsu were mentioned; the colors of the dongdari and jeonbok of dangsanggwan and danghagwan were referenced in various colors. It was presented as an illustration of costumes that could be used to produce objects accurately reflecting the above historical results. The basic principle of the illustration was to present the modeling standards for 3D content production. Samples of form, color, and material of the corresponding times and statuses were presented. The front, the side, and the back of each costume and its accessories were presented, and the colors were presented in RGB and CMYK.

본 논문은 미국 의학연구소(US Institute of Medicine, IOM)와 미국 농무성의 식이지침 자문위원회(USDA Advisory Committee on Dietary Guidelines, DG)에서 발표한 권위 있는 종설 들과 미국 영양사협회 학술지를 포함하여 여러 학술지에 발표된 의미 있는 종설 들의 내용을 종합한 것으로 일부의 내용은 그들의 의견을 그대로 반영하였다. 당은 단당류와 이당류를 말하며 당에는 포도당, 과당, 갈락토오즈, 맥아당, 서당과 유당이 포함된다. 당의 식품급원으로는 고과당 옥수수시럽, 사탕수수, 꿀, 사탕수수, 맥아시럽 등이 있다. 당은 미국 식약청에서 일반적으로 안전하다고 인식(generally recognized as safe, GRAS)되고 있다. 당은 에너지를 공급하며, 정신적인 만족감을 부여하는 기능을 가지고 있다. 대부분의 과일과 유제품은 당을 많이 함유하고 있으며, 건강한 식사를 구성하는 식품으로 섭취되고 있다. 당은 또한 조리와 가공과정에서 식품의 맛과 기능적인 면을 향상시키기 위해 첨가되기도 한다. 당은 영양밀도가 높은 식품/음료의 기호성(palatability)를 향상시키므로, 감미료들은 건강한 식사가 되도록 도와줄 수 있다. 그러나 첨가당의 섭취가 증가되면 식사의 영양밀도가 감소하는 가능성에 대한 우려가 있다. 여러 연구에 의하면 첨가당의 섭취가 총 열량 섭취의 25% 이상이 되면 식품의 영양밀도 감소가 나타날 수 있다고 보고하고 있다. 한국에서 추정된 당의 섭취량은 이것보다는 매우 낮은 수준이다. 선진국들에서 당의 섭취가 건강에 부정적인 영향을 줄 수 있다는 가능성에 대해서는 많은 논란이 되고 있다. 그러나 적절한 양을 섭취하는 범위에서 당의 섭취 자체만으로는 비만, 당뇨병, 대사증후군과 고콜레스테롤혈증의 위험이 증가되지 않는다는 과학적인 연구보고들이 있다. 그러므로 IOM은 "여러 자료에 근거하여, 충치, 행동적인 문제, 암, 비만의 위험성과 고지혈증의 위험성에 있어서 총 당과 첨가당에 대한 상한섭취량(tolerable upper limit)을 설정하는 것에 대한 증거가 불충분하다"고 결론을 내리고 있다.

Although Euonymus alatus (EA) has been used as traditional medicine for cancer treatment, exact substances involved in curing of the disease are not yet known. Free radical scavenging and reactive oxygen species (ROS) removal activities of aqueous extract components isolated from winged stem of EA in animal cell line were investigated. Aqueous extract of EA (AEEA) was fractionated by ultrafiltration. All fractions mainly consisted of polysaccharide (44.8%), protein (2.1%), small amounts of phenol compounds and organic acids. Antioxidant activity of AEEA increased depending on concentration fractions, as determined by 1,1-diphenyl-2-picrylhydrazyl method. ROS removal activity was visualized in Chinese hamster ovary cell line using laser scanning confocal microscope, and AEEA activity increased in order of F IV>F III>F I>F II. These results suggest AETA has bioactive carbohydrates with potentials as functional foods and antioxidants.

The tail portion of dried 6-year old white ginseng was extracted and sugars and nitrogen compounds were also evaluated for chemical properties depending on varying conditions of extractions. The factors studied were extraction temperature in the range of 70-$100^{\circ}C$, ethanol concentration of 0-90% and the times of extractions which was taken 8 hours per each extraction in water at $80^{\circ}C$. For the effect of ethanol concentration in the extraction solvent, it was found that the amounts of free, reducing and total sugars and starch recovered in extract were almost linearly decreased along with the increase of concentration and the nonprotein nitrogen accounted over 84% of total nitrogen in extract. As ethanol concentration became increased, extractions of total nitrogen and water souluble nonprotein nitrogen were decreased especially in 90% ethanol. For the extraction temperature, all the sugar fractions with water and 70% ethanol except free sugar have tended to increase along with the temperature raised from 70 to $100^{\circ}C$ and it was found there is little changes of nitrogen compounds in the temperature range except a rapidly increase in water soulble protein at $100^{\circ}C$. For the times of extractions, showed that most of extractable compounds were extracted in 3 times of extractions with water at $80^{\circ}C$. It was shown that more than 95f) of sugars and 80% of nitrogen compounds were yielded with water extraction. Accordingly it was efficient to extract with water or 70% ethanol in 3 times in terms of !actor and energy consumption.
