  • In the Joseon Dynasty, various fruit teas were popularized to promote health, with spread of Donguibogam and Hyangyag gugeupbang. As interest in fruit tea has recently increased, studies on its manufacture have become necessary. We used response surface analysis for rediscovery and commercialization of grape tea. Major materials of traditional grape tea are grape juice, pear juice, ginger juice, and honey, and the sugar contents of these materials were 12.3, 14.1, 3.3 and 75 $^{\circ}Brix$, respectively. When sensory examinations were conducted with subjects aged 40-60 years, the difference between dilution ratios of 100% and 150% was not significant, but tea diluted by 150% showed somewhat higher scores than did tea diluted by 100%. Ginger taste and sweetness were found to have the greatest effect on overall acceptance. Regression analysis on color, flavor, taste, and overall acceptance values, with reference to ginger juice and honey as independent variables, revealed that the $R^2$ values were 0.8411, 0.6717, 0.9499, and 0.9015, respectively. Contour maps were superimposed to obtain an optimal combination of ingredients for traditional grape tea, and the indicated levels of ginger juice and honey were 0.46-0.69% and 3.85-5.20%, in combination with grape juice, pear juice, and water concentrations of 28%, 9% and 60% (all w/w), respectively. Thus, it is now possible to prepare traditional grape tea.

  • Effects of some artificial diets containing pulverized silkworm pupae On the oviposition of a green lacewing, Chrysopa formosa, were studied. The pulverized silkworm pupae with honey seemed to be a good diet for the egg-laying activity of field-collected adults in the beginning of rearing, but their fecundity progressively decreased. Newly emerged adults. did. not lay eggs when fed the above diet, but they were able to lay eggs when the silkworm pupae were defatted and provided with honey. An adult female laid an average of 166.8, 110.2, 96.1, and 66.1 eggs after spending 5, 9, 9, and 11 days for the initiation of oviposition when supplied with various diets i.e. the cabbage aphid, defatted silkworm pupae with additive constituents, mixture of intact and defatted silkworm pupae with additive constituents, and defatted silkworm pupae with honey, respectively.

  • The burn is acute skin injury caused by fire, hot water. steam. hot oil, sour and salty. It is occurred frequently in the daily life as well as oriental therapy like moxibustion therapy, physical therapy. Nevertheless, medical treatment of the burn is almost dependent on western cure. So we chose the oriental medicine textbooks and the oriental medicine journals that were dealing with the drugs, processing the drugs. peculiar treatment put first external cure. The results were as follows; 1. The burn is acute skin injury caused by fire, hot water, steam, hot oil, sour and salty. 2. The burn cause blisters, irritability and restlessness, nausea, dryness of mouth, constipation, in case of serious, coma, dyspnea and death. The early stage of the burn, blisters form by skin damage and they burst into skin ulceration from which pus issues, the latter term, the wound form scab and healed up. 3. In a light case, medical treatment of the burn was used external treatment by medicine for externalism use, in a serious case, it was used both as an internal remedy and medicine for outward application. Also in the early stage, it was careful of using the cold and cool medicine, as the process of healing, it was used alleviating pain, detoxicating, moistening the skin, growing muscle and skin, convergence, evacuating pus, regeneration of the tissue, strengthen the spleen and nourishing the stomach. 4. The external treatment medication is Herba Ephedrae Oil(麻油), Radix ET Rhizoma Rhei(大黃), Glauberitum(寒水石), Water(水), Pig OiI(猪油), Pig Fat(猪脂), Radix Angelicae Gigantis(當歸), Rhizoma Coptidis(黃連), Cortex Phellodindri(黃栢). The White of an Egg(鷄子淸), Raw Honey(生蜜), Honey(蜜), Wine(酒), Etc. It is mostly the cold and cool medications. 5. Soft extracted and powered dosage form in external treatment is much used. The soft extracted form(32times used) are mostly Chung Ryang paste(淸凉膏) and Fructus Papaveris paste(罌粟膏). The powered form(30times used) are mostly Bingsang Powder(氷霜散), Bosaenggugo Powder(保生救苦散), Sahwang Powder(四黃散). The others is much a various powder adding solvent. 6. If varicella stage, erosion after varicella stage, oozing stage and extreme pain stage, the powder adding solvent is much used. If little oozing stage. ulcering stage, scabing stage and a chronic stage, Soft extracted dosage form is much used. 7. The most many(26.65%) used method is that apply each medication power mixed water(水), wine(酒), honey(蜜) in a wounded part.

  • Tilia amurensis is an important honey plant. As T. amurensis mainly distributes mountainous area with various elevations in Korea, accurate prediction of blooming time at the different elevation would benefit forest beekeepers. In this study, we measured time-dependent blooming progress of T. amurensis in Mt. Gariwang area ranging from 500-1500m. Additionally we collected blooming data from web and published literatures and estimated the variation of blooming time relative to the geographic locations. Flowers began to bloom from July 6 to July 22 with full blooming on July 14 in location where elevation is 638m in Mt. G ariwang area in 2021. Based on these databases, a growing degree day (G DD) model was developed for prediction of T. amurensis blooming progress using average daily temperatures. Using the starting date of G DD accumulation of January 1 and base temperature of 5 ℃, blooming period ranging from 10% to 90% of cumulative blooming rate was estimated as 860-1198 degree days (DD). This corresponded to the beginning to the end of July in Mt. Gariwaning area in 2021. This model could explain the phenological variations of T. amurensis flower blooming possibly affected by elevation within geographic area, latitude or year relative to the climate change, and aid forest beekeepers for better timing of nectar foraging by honey bees.

  • The study was conducted to establish the method of performance test of honeybee queens under Korean environment. Colony performances of Apis mellifera were tested based on wintering ability, colony population and honey yield in Sangju, Korea from November, 1999 to October, 2001. The results of performance-testing on the honeybee colonies are summarized as follows: The colony weights measured before and after wintering in 1999~2000 season were averaged $22.6{\pm}2.6kg$ and $20.1{\pm}2.6kg$, respectively, showing the decrease of $2.5{\pm}0.7kg$. During 2000~2001 winter season, the colony weight before wintering was $22.6{\pm}2.3kg$ and was decreased by $2.3{\pm}0.6kg$. The number of combs well covered with bees was $13.1{\pm}4.6$ as measured on the 22nd of May. 2000 and $16.0{\pm}3.8$ on the 21st of May. 2001, respectively. The rate of supering colonies were 50% and 98.5% in 2000 and 2001, respectively. The amount of honey production was $12.7{\pm}8.6kg$ per colony in 2000, and $14.2{\pm}7.6kg$ per colony with unselected queens and $23.5{\pm}4.9kg$ per colony with selected-tested queens in 2001, which were harvested two times during main nectar flow season of black locust, Robinia peseudoacasia.

  • Hygienic behavior of Honey bees, Apis mellifera, was evaluated by uncapping and removing ability of dead broods from the nest. Hygienic behavior is originated from quantitative traits, which are expected to express key roles in colony defense against mite parasites and bacterial and fungal diseases. It is regarded as one of important characteristics of honey bee's resistance to parasites and pathogens. In this study, five inbreed and two hybrid lines of A. mellifera, the former five inbreed lines, which have been reared for over eight years at the National Academy of Agricultural Science in Korea, and the latter two hybrid lines, which have been bred by crossing between the inbreed lines, were investigated on their hygienic behavior by a pin-killed brood assay at 12hrs and 24hrs after treatment. The results indicated that after 12hrs one inbred line was proved to be hygienic (removal rate of dead brood >90%), three inbred and two hybrid lines showed intermediate behavior, and one inbred line belonged to non-hygienic (removal rate of dead brood <70%). However, after 24hrs, only one line was considered to be intermediate as removal rate was below 90%, thus all except this line had shown hygienic behavior.

  • Objectives : This study first acknowledges that cough, which is a light symptom, can act as a link that leads to more serious disease. With this acknowledgement, the study ponders upon how the people of the past, before the introduction of western medicine, attempted to cure the first sign of cough and how to stop it from developing. Methods : China's Eumsunjungyo and Sikgamboncho, and Chosun's Singnyochanyo and Donguibogam are used mainly to analyze the food cure that were used in relation to sea water, and to discover what types of ingredients and preparation forms were used, how they were taken, what types of food cure there were, and how they were used. Results : There was no ingredient used commonly in all of the four literatures. Eumsunjungyo utilized ingredients related to lamb. Singnyochanyo and Donguibogam were both used in Chosun, but some similarities with the Chinese literatures were discovered in terms of food cure since they were put together with their Chinese counterparts as references. Ingredients that were used commonly in two or more of the literatures were ginger, taoren, xingren, honey, pear, liyu, and pig lung. Conclusions : Some staple folk remedies that later becamce cultural cuisines included drinking the water from boiling pear and honey and boiling and eating pears with peppers stuck in them. The eating of ginger together with korean traditional taffy have taken its own form and became saenggang jeonggwa and pyeongang. The oriental food cure method has been continuing among the folk people in the form of traditional food with the food philosophy of edible homologous as its basis.

  • This study was conducted to investigate the contents of lead (Pb) and cadmium(Cd) in honeys (n=60) from April to May in 2004 and to provide the scientific basis for heavy metal regulations of Korea Food Code. The samples were digested with acids, then analyzed for the contents of Pb and Cd by an inductively coupled plasma spectrometer (ICP). The contents of Pb and Cd [minimum-maximum (mean)] were 0.189-1.82 mg/kg (0.568) and not detected (ND)-0.016 mg/kg (0.0008) in domestic acacia honeys (n=20), ND-1.702 mg/kg (0.329) and ND-0.243 mg/kg (0.013) in domestic wild flower honeys (n= 18), ND-0.322 mg/kg (0.073), ND-0.027 mg/kg (0.002) in imported honeys (n=13), ND-3.754 mg/kg (0.671) and ND-0.658 mg/kg (0.073) in foreign honeys (n=9) brought by Korean travellers, respectively. According to the results, foreign honeys brought by Korean travellers were detected with the highest level of Pb and Cd. Therefore, we recommend that heavy metals of domestic and foreign honeys should be continuously monitored. It is also thought that these results could be the important references to establish the standard of Pb and Cd in honey.

  • The aim of this research is to develop recipe of kimchi beverage made of sun-dried salt. A distinction between this recipe with existing ones is the Korean traditional ingredient, sun-dried salt. The variety and amount of recruitment on the beverage was established after its characteristics were investigated by sensory tests. Preference of sweetening agent for the beverage was oligosaccharide > honey > sugar powder > sugar > aspartame > pear juice. While sensory evaluation was conducted on color, flavor and overall acceptance, the overall acceptance scores are as following; 6.24 for watery radish kimchi, 6.00 for white kimchi and 5.76 for Korean cabbage kimchi. Among other beverages, watery radish kimchi beverage was preferred. Amount of kimchi for the beverage was most suitable at 10 % of the contents. It was the same with all the other beverages. When the products were stored in normal temperature, the evaluation scores dropped for all sensory items as time passed.

  • Lipid oxidation and antioxidant stabilities of nut-sesame yeotgangjeong (Korean traditional candy bar) with different binders were evaluated during storage in the dark. S1, S2, and S3 binders consisted of starch syrup, sugar, and water (58:34:7.6, w/w/w); starch syrup, jocheong, honey, trehalose, and water (43.5:11.6:2.9:34:7.6, w/w/w/w/w); and starch syrup, jocheong, honey, sugar, trehalose, and water (43.5:11.6:2.9:17:17:7.6, w/w/w/w/w/w); respectively. Lipid oxidation was determined by peroxide and p-anisidine values, and tocopherol, lignan, and polyphenol contents were determined spectrophotometrically. Peroxide values were significantly higher (p<0.05) in yeotgangjeong samples with S2 or S3 binder than in those with S1; however, the converse was true for tocopherol degradation. Lignan was the most stable antioxidant in yeotgangjeong. The results suggest that tocopherols have a priority over lignans to control the lipid oxidation of yeotgangjeong during storage; reduced lipid oxidative stability after substituting sugar with trehalose might be because it increases oxygen diffusivity and inhibits the antioxidant action of tocopherols on lipids.
