  • The purpose of this study was to obtain the basic data on clothing habits for health promotion through the investigation of clothing weight by month and season. Thirty six subjects (18 males and females twenties) were composed to obtain the clothing weight(Total clothing weight) for a year. And then clothing weight was grouped in to four seasons : spring(Mar-May) Summer(Jun-Aug) Fall(Sep-Nov) and Winter(Dec-Feb). The data of males and females were respectively divided into three groups by cluster analysis with clothing weight. 1. The clothing weight of male and female were the heaviest in jan, that of male were smallest in July female in Aug. 2. The clothing weight mean of male(996g/m2) were heavier than that of female(894g/m2) for year. The seasonal clothing weight of male culminated in Winter(1179g/m2) and decreased respectively : Spring (973g/m2) Fall(879g/m2) and summer(559g/m2) The seasonal clothing weight of female culminated in Winter (1068g/m2) and decreased respectively ; Fall(865g/m2) Spring(835g/m2) and summer(479g/m2). The seasonal clothing weight variations were significantly different in each season(p<0.01) but they were insignificantly different between Spring and Fall. middle and light. There was individual differences in the clothing weight especially large in Winter and Spring and small in Summer and Fall. 4. Lower inner clothing weight was the lowest fluctuant all around year upper outer clothing weight was the most fluctuant. So he/she controled upper outer clothing to deal with thermal environment. He/she pretended natural textiles such as cotton and wool to synthetic textiles.

  • This study was conducted to investigate the weight of crown part effect on growth and bolting response of Ostericum koreanum Kitagawa. Bolting rate with crown part weight was represented 0%, 0%, 4.1%, 12.9%, 25.1%, 34.9% corresponding to each crown part weight 5 g, 10 g, 20 g, 30 g, 40 g, 50 g. The heavier the crown part weight was the higher the direction rate rose and the flowering time came earlier. The dried root amount was the highest at 30 g and crown part number, the length of root, and crown diameter showed all the highest figures at 30 g. The relation between amount per 10 g and outcrop weight increased on secondary regression formula as weight increased and reached its peak at 29.7 g and then decreased over 29.7 g.

  • This study was carried out to investigate the effect of body weight of queen on the developmental characteristics of foundation queens in the Bombus ignitus collected in Korean locality. Queens were classified into six groups based on their body weight (i.e., 0.4 g, 0.5 g, 0.6 g, 0.7 g, 0.8 g and 0.9 g). The average weight of 200 foundation queens collected was 0.657${\times}40.095 g and 0.6 g-class was most abundant (38 %) among six weight classes. The queen that had the heavy body weight showed the trends of higher rate of oviposition, colony foundation and progeny-queen production and shorter periods of preoviposition and colony foundation, suggesting the positive correlation between the body weight of queen and colony developmental characteristics. Also, the numbers of worker and progeny-queen emerged from the queen with heavy body weight were slightly higher than those with light body weight queen.

  • Both ODC and PRDM16 genes were known to be associated with body weight traits in chicken. These two genes were located on GGA3 and GGA21, respectively, where the QTLs of body weights are located. Therefore, the objectives of this study were to identify the SNPs in these two genes and their associations with body weight traits in Korean native chicken. Fluidigm Dynamic Array integrated fluidic circuits (IFCs) assay was used to genotype 7 SNPs consisting g.-353C>T, g.2136A>G, g.2524T>C, g.3607C>T SNPs of the ODC gene, and g.182216C>T, g.182290A>T, g.182491A>T SNPs of the PRDM16 gene. Statistical analysis showed that g.2136A>G SNP of the ODC was associated with body weight at 20 weeks of age and slaughter weight, and g.3607C>T SNP of the ODC was associated with body weight at 2 weeks of age. Association between g.182216C>T SNP of the PRDM16 and body weight at 12 weeks of age has also been revealed. In addition, g.182491A>T SNP of PRDM16 has significant correlation with body weight (BW) at 8 weeks, BW at 10 weeks and BW at 14 weeks of age. These results suggested that both ODC and PRDM16 could be strong candidate genes for body weight traits in Korean native chicken.

  • American ginseng plants (Panax quinquefolium L.) of various ages were harvested every two weeks during each of three growing seasons and dry matter yield of components and root respiration determined. Shoot dry weight was about 0.5 g, 2.5 g and 4 g for 2, 3 and 4-year-old plants, respectively and fruit dry weight was as much as 50% of this in 3- and 4-year-.old plants. Root dry weight decrease by 30~50% as shoots emerged and at the end of the season was about 2 g, 3.5 g and 5 g in 2, 3, 4 and 5-year-old plants, respectively. Shoot and root dry weight were linearly related with an approximate 1:2 ratio. Root respiration rate at 2$0^{\circ}C$ in the dark was about 5 $\mu\textrm{g}$ CO2 g-1 DW(dry weight) min-1 in the early season, then doubled within 50 days as shoots emerged, and thereafter declined over the season to 2~5 $\mu\textrm{g}$ CO2 g-1 DW min-1. The Q10 for dark respiration over the interval from 10 to 2$0^{\circ}C$ was 1.58. Root respiration rate and shoot growth rate was positively linearly related in all ages of plants. Key words: Dry weight, partitioning.

  • This experiments was conducted to determine the effect of dietary fiber(DF) levels with diets of isocaloric (3,010 kcal/1kg diet) and isoprotein(21% of diet) on colored brolier chicks(Juk jun hatchery farm). Four groups of 6 chicks 4 replication. were fed corn-soy meal diets containing 0% (DF, 5%), 2%(DF, 6%), 4%(DF, 7%), and 6%(DF, 8%) of dehydrated alfalfa meal(AM) from 21 to 42 days of age. The addition of dietary fiber levels to the broiler chicks diets did noty affect body weight, feed efficiency, energy efficiency and protein efficiency, but affect feed intake of chicks fed 6% of fiber. The level of fiber diets did not affect gizzard weight of female(1.45g/100g BW) and male(1.25g/100g BW), but affect small intestine length of female. When comparing two the dietary fiber levels, 5% and 8%, the contents of the total serum cholesterol was slightly higher in chicks fed 5% of fier than that of 8% without significant. However, total serum cholesterol levels of female(121mg/dl) and male(119mg/dl) were not influenced by increased dietary fiber levels. The liver weight was not influenced by increasing of dietary fiber levels (female 2.03g and male 2.05g/100g BW). The yields of dressed weight(72% of shrunk body weight), skin weight)11% of dressed weight) were not influenced by increased dietary fiber.

  • In order to elucidate the relationships between cadmium, copper, mercury, zinc levels and metallothionein in the liver and kidney cortex of Korean, the levels of Cd, Zn, Hg, Cu and metallothionein (MT) were determined in the kidney cortex and liver of 50 subjects deceased in the period of January-November, 2001 in the area of Seoul and Gyeonggi Province of Korea. The mean age of the population studied was 36.3+/-12.3 years. The tissues were digested with microwave digestion system and the elements were determined by inductively coupled plasma atomic emission spectrometry. MT was determined by the Cd-hemoglobin affinity assay. The determined levels (mean+/-SD) were: 33.9+/-18.9 micrograms Cd/g wet weight; 47.5+/-12.6 micrograms Zn/g wet weight; 2.5+/-0.57 microgram Cu/g wet weight; 0.26+/-0.31 micrograms Hg/g wet weight, 4.0+/-3.1 mg MT/g wet weight in renal cortex and 2.5+/-1.9 micrograms Cd/g wet weight; 46.9+/-15.0 micrograms Zn/g wet weight; 6.2+/-2.5 micrograms Cu/g wet weight; 0.10+/-0.15 micrograms Hg/g wet weight, 0.92+/-0.57 mg MT/g wet weight in the liver. Positive relationships between Cd and MT, sum of four divalent metal and MT in the kidney cortex were observed. No other correlation was found between Cu and MT, Hg and MT, Zn and MT in either organs.

  • The plant growth and yield of Pinellia ternata (Thunb.) Breit. were studied by altitude and tuber weight. The emergence rates in low land area were not different by tuber weights, but it showed earlier emergence date in heavier weight of seed-tuber and low land area. The higher aerial growth such as plant height and number of leaves per plant was the heavier tuber weight in a planting year, but the growth was not different by the weight of tuber at second year after planting. The distribution pattern of tuber size per $m^2$ was not influenced by different seed-tuber weight. The number of harvested tuber was highest at more than 1 g of tuber weight, and followed 1~2 g and less than 2 g. The distribution pattern of fresh tuber yield was not influenced by different altitude and seed-tuber weight. The marketable tuber, 2 g or more, tends to be produced with more than 0.6 g seed-tuber. As the results above-mentioned, it was thought that the high yield was supposed to use seed-tuber over 0.6 g in the fertile soil.

  • Ninety KNP were divided into three group by differential market weight(20 of each group): Live weight of Group 1(G 1), Group 2(G 2) and Group 3(G 3) were 50-59kg, 60-69kg, 70-80kg, respectively. Values of pH and shear force showed an increase, while cooking loss showed decreased with increased weight. In color analysis, $a^{\ast}$ value in meat and $b^{\ast}$ value in backfat of KNP showed higher as slaughter weight increased. Slaughter weight did not significantly affect the fatty acid composition of subcutaneous fat of KNP. With the exception of oleic acid in intermuscular fat, there were no significant weight-dependent differences in the fatty acid profiles.
