  • Eurasian black vulture (Aegypius monachus) belongs to family Accipitridae and is a raptor preying small birds and mammals. It is a wintering bird residing from the mid of November to the late of March in Korea. Although Eurasian black vulture population wintering at Korea is gradually increased, the efficient rescue and treatment for injured Eurasian black vultures are still problematic, due to lack of basic data. Therefore, in this survey, to obtain basic resources for establishing more efficient rescue system, we surveyed the number of Eurasian black vultures wintering at Gangwon province, wintering ecology and injury state of Eurasian black vulture. Survey area was Togyo reservoir at Cheorwon, Seonan basin at Yangoo and Wolsong reservoir at Chuncheon from November 2004 to March 2005. From 12 rescued Eurasian black vultures, physical examination, total plasma protein (TPP) and packed cell volume (PCV) were measured. To survey injury state of Eurasian black vultures wintering at Gangwon province, we surveyed the cause, morbidity and mortality from 103 Eurasian black vultures, based on medical records from animal rescue teams. The number of eurasian black vultures were gradually increased from November, peaked at Feburary, then steeply decreased at March. Eurasian black vultures showed the most vigorous activity around 1 PM within a day. In physical examination, mean body weight was $9.6{\pm}1.22kg$, body length was $1130{\pm}45.4mm$. No statistically significant difference in body weight and length between male and female eurasian black vultures was observed. Mean PCV was $40.2{\pm}2.7%$, while mean TPP was $5.86{\pm}0.8mg/dl$. The most common cause of injury and mortality was intoxication, while that of morbidity was fatigue.

  • This study analyzed the intake of calories and nutrients based on the consumption of black beans. The survey was conducted on 124 college students (male: 42, female: 82), of whom 63.7% (79 students) were consumers of black beans. The calorie intake of the black bean intake group (1599.81±555.48 kcal) was significantly higher than that of the non-black bean intake group (1259.99±507.58 kcal) (P<0.01). The black bean intake group also showed a significantly higher intake of crude protein (P<0.05), plant protein (P<0.01), animal protein (P<0.05), crude fiber (P<0.001), plant calcium (P<0.001), plant iron (P<0.001), zinc (P<0.01), vitamin B2 (P<0.01), vitamin C (P<0.01), vitamin E (P<0.01) and folic acid (P<0.001) compared to the non-black bean intake group. There was a positive correlation between the frequency of black bean intake and crude fiber (P<0.05), plant calcium (P<0.05), plant iron (P<0.05), and folic acid (P<0.05). Overall, the black bean intake group was more likely to eat black sesame 13.82 times (95% CI=5.37, 35.55), white beans 10.79 times (95% CI=3.53, 33.02), mung beans 7.22 times (95% CI=2.58, 20.23), and brown rice 4.72 times (95% CI=1.88, 11.84), than the non-black bean intake group. In conclusion, we believe that black beans constitute a vital food ingredient that is necessary to provide Korean college students with a well-balanced diet.

  • The black soldier fly is economically important because its prepupae are used as feed for many animals, including fish and swine. In Korea, black-soldier-fly farms have attempted to increase annual breeding and mass egg production for use in animal feed, as well as the decomposition of organic waste. Such efforts require an understanding of optimal mating and oviposition techniques. Specifically, adult densities and cage size may both improve the efficiency of mass egg production. Our study used four sizes of nylon cages ($1.0{\times}1.0{\times}2.5m$, $1.5{\times}1.5{\times}2.5m$, $2.0{\times}2.0{\times}2.5m$, $2.5{\times}2.5{\times}2.5m$) and three density treatments (4 kg, 8 kg, and 10 kg of pupae) to investigate optimal habitat size and adult density. We found that cage size (independent of density) did not significantly influence female fecundity (number of egg clutches and egg weight), whereas higher densities increased egg number and weight regardless of cage size. Thus, we recommend manipulating adult density to enhance productivity in commercial black-soldier-fly farming. However, we also propose further detailed research to develop methods that account for seasonal changes and environmental conditions, as climatic variables (temperature, sunlight) likely influence female fecundity as well.

  • Background: The recent, decline in Black-berry Magnolia Vine (Schisandra repanda; BMV) native to Jeju Island, Korea, has raised concerns about the causes of this decline. We investigated the native environment of S. repanda and evaluated its propagation through cuttings to provide preliminary data for its restoration in Jeju Island. Methods and Results: The native environment of the BMV in the Hallasan National Park was surveyed and the climatic variables (temperature and humidity) were analyzed. The effects of the sex of the donor plant (male/female) type of cutting (softwood/hardwood), and treatment with a plant growth regulator (indole-3-butylic acid/rootone) on the rooting of BMV were investigated. Additinallly, the rooting rate, root count, and root length, as well as temperature and humidity were measured in the vinyl moist chambers. BMV was observed in 63 plants distributed from 567 m to 1,364 m above sea level of the Hallasan National Park. In the cutting experiment, the rooting rate was 71.9%, and it was higer in female plants (75.0%) than in male plants (68.8%). Conclusions: The mass propagation of BMV through cuttings valuable for its restoration as without such safeguard measures, the population could face extinction within a few decades.

  • Larvae and pupae of Simulium (Eusimulium) satsumense were collected and recorded from Korea for the first time. Detailed descriptions and photographs of both immatures are provided. Currently, 42 species are known from the subgenus Eusimulium, which is found globally, mainly in the Holarctic Region, but unknown from Korea. Members of the subgenus Eusimulium are morphologically homogeneous in male, female, and pupa, making them extremely difficult to distinguish from one another. S. (E.) satsumense can be distinguished from other Korean black flies by the following combination of the characteristics: Pupa: Gill of four slender filaments, dorsalmost filament strongly divergent from other filaments; cocoon slipper shaped without anterodorsal projection; Larva: Head spots distinctly positive; postgenal cleft short, apically rounded or squared; antenna with proximal segment brown; abdominal segments IX with prominent ventral tubercles; and rectal papillae of three simple lobes. In addition to descriptions for larvae and pupae of the species, a key to genera and subgenera of Simulium of Korean black flies are also provided.

  • The objectives of this study were to identify the dimensional structure of female impression formation based on ornaments and color of jacket, and to analyze the effect of ornaments, color of jacket, and perceiver's gender on impression formation. The experimental design was 3$\times$4$\times$2(ornaments$\times$color of jacket$\times$gender) factorial design by 3 independent variables. The stimuli of color photographs of female model and the semantic differential scale were used. Samples were 288 college males and females. The data were analyzed by factor analysis, ANOVA, duncan's multiple range test, and t-test. Four factors derived to account for the dimensions of impression formation. These were potency, elegance, evaluation, youthfulness, and feminine. Wearing of large ornaments(a necklace and earrings) had a negative effect on impression of elegance and positive on potency. Red jackets increased the impression of positive evaluation, potency, feminity, and youthfulness. On the jackets of achromatic color such as white and black, wearing of large ornaments increased the effect of potency, and large ornaments increased matured impression on black jacket. The results of this study mean that perceiverss used large ornaments and red jackets as a salient cue.

  • At the altitude of approximately 250 of Mt. Sori located in Kyung-gi Co, Korea authers have made a field collection of Drosophila during June, 1 and 15, 1961, and found about 30 specimens which seemed to be a new species belonging to Genus Drosophila, Subgenus Hirtodrosophila. AUthors have named the species : D. macromaculata sp. nov. " Its Korean name is given , : Uluck-muni-chopari". This species is very similar to Drosophila cheda in its external feature and especially it that each of four stripes in the mesonotum is cut into tow, and it also resembles with Drosophila calloptera in that it has three distinct spots in the wing. Its first segment of abdomen is yellow-brown in color while both end points are black. The second segment is black and in its middle part there yellow-brownish strips of V form, the peripheral part of which are found two spots of yellow brownish color. On third to fifth segments of male and on third to sixth segments of female there are fod-form spots, one on each segment, and on both sides of these rods two smaller spots are found in each segment. This species is clearly a fungus feeder and its breeding in authers laboratory is at present, not attained. Holotype : male , Kwang-nung, Kyung -gi Do, South Korea, 1 Male June, 1, 1961. Allotype : female, collected together with holotype. Paratype : Kwang-nung, Male 16 and female 12. Distribution : South Korea. Collecting method : Net sweeping on the decayed trees.yed trees.
