Adults of Prosimulium kiotoense and Twinnia japonensis were collected and reported from Korea for the first time. Since adult black flies are notorious for morphological homogeneity particularly in female, larval and pupal characters have been mainly used to identify them. Adults of P. kiotoense can be identified by the following combination of characteristics: Adult, wing with radial sector (Rs) branched into R²⁺³ and R⁴⁺⁵; hind leg basitarsus without calcipala; first tarsomere without pedisulcus. Female, claw without basal thumblike lobe; hypogenial valve elongate, convex, heavily sclerotized medially, posterior end touching each other, space between valves rhomboid. Male, claw with basal thumblike lobe; ventral plate keel shaped; gonostylus with 2-3 spinules. Adults and pupa of T. japonensis can be identified by the following combination of characteristics: Adult, antenna with 7 flagellomeres. Female, hypogenial valve broad, posterior end of valve not touching each other; cercus elongate, subquadrate; spermatheca slightly wider and long, round. Male, claw with basal thumblike lobe; gonostylus with 1 spinule; ventral plate flat. Pupa, gill of 16 filaments, arising from 3 swollen stalks; abdominal tergites without spine combs except tergites III and IV with small recurved hooks; terminal spine well developed, wavy shaped.

Objectives: This research aimed to compare perceived stress among unemployed younger adults in South Korea and the UK, particularly the relation between perceived stress levels of unemployed younger adults and their perception of their level of social support including family support and community support. Method: In order to achieve a research purpose, this study undertook a quantitative analysis of 306 unemployed younger adults in portal sites of job recruiting centers in the UK and South Korea from the period of June to July 2014. Results: The analysis found that unemployed younger adults in the UK perceived higher levels of social support, family support among social support, and community support among social support than that of South Korea. Secondly, in the UK perceived levels of social support and community support among female unemployed younger adults outweighed that of male ones. Thirdly, in the dimension of perceived stress, unemployed younger adults in two countries reported opposite results via social class.

In this study, 25 science textbooks developed under the 7th National Curriculum were analyzed for gender-role stereotyping. A total of 3549 (17.9%) illustrations including persons were selected from 19810 illustrations from the textbooks. The frequencies of men and women appearing in them were counted, and the types of activities and the characters of people in them were analyzed. Male pupils and adults appearing in the textbooks were more frequently than female, and the difference between male and female adults was very great. However, the characters of pupils and adults were found to be active regardless of their age and gender. The jobs of male adults were depicted to be more diversified than those of female. Scientists appearing in the textbook illustrations also were mostly male.

Insufficient dietary intake of vitamin A is one of the major nutritional problems for elderly adults in some parts of Korea. The objective of this study was to determine the vitamin A nutritional status of elderly adults in Asan, Korea by assessing the dietary intake and serum retinol concentration. Five hundred twenty four subjects (218 male and 306 female) over 65 years were recruited from city of Asan. Each subject was interviewed to assess the intake of vitamin A using a 24hr recall method and data were analysed from computer-aided nutrient analysis program. Blood samples after 12hr fasting were collected for serum retinol concentration and reverse phased HPLC with UV detector used. The results showed that subjects did not consume the sufficient amount of energy (82-85% of Korean RDA for male and 77-79% RDA for female) and vitamin A (59% RDA for male and 50% RDA for female). Range for retinol intake was 0 to $4342\;{\mu}g$ a day while that of beta-carotene was 65 to $31595\;{\mu}g$. Serum retinol concentrations were within a normal range for both male ($80\;{\mu}g/dl$) and female ($67\;{\mu}g/dl$) subjects. Many subjects (n=342) consumed less than 50% RDA of vitamin A. However, if retinol intake was high (> $37\;{\mu}g$), even with less than 50% RDA of vitamin A intake, serum retinol concentration was high ($75\;{\mu}g/dl$). Subjects showed normal serum retinol status even with low vitamin A intake. The results suggested that optimal intake ratio of dietary retinol and carotenoid is important to maintain an appropriate serum retinol concentration.

This study investigated the effects of Lavandula angustifolia (L. angustifolia) aroma on the brain electrical activity evaluated by an electroencephalogram (EEG) in the male adults since many researches were performed with females and few with males. Sleep quality of 35 male adults were analyzed by Pittsburgh sleep quality index, and they were divided into two groups of good sleep quality and poor sleep quality. EEG electrodes were attached at the frontal (F3, F4), temporal (T3, T4), occipital (O1, O2), and parietal (P3, P4) regions according to the International 10-20 system. EEG was measured for 3 min per each period of before, during, and after L. angustifolia aromatherapy. Subjects with good sleep quality showed increases in the delta power at the parietal region of both cerebral hemispheres and in the theta power at the temporal region of right hemisphere (p<0.05), and a decrease in the alpha at the parietal region of both cerebral hemispheres (p<0.05). And subjects with poor sleep quality showed increases in the delta power at the frontal region of left cerebral hemisphere and in the theta power at the frontal region of both hemispheres (p<0.05). It is concluded that L. angustifolia aroma has effects on decreasing an awakening status related-brain wave and increasing the sleep status related-brain waves in the male adults with good sleep quality, and has also effects on increasing the sleep status related-brain waves in the male adults with poor sleep quality.

The purpose of this study was to investigate male adult' appearance management behavior according to objectified body consciousness. The subjects were 648 male adults aged from 20 to 59 and measuring instruments consisted of objectified body consciousness, appearance management behavior, and subjects' demographics attributions. The data were analyzed by Cronbach's ${\alpha}$, factor analysis, cluster analysis, multiple response analysis, cross tabs analysis, ${\chi}^2$ test, and t-test. The results were as follows. First, 3 dimensions (body shame, body surveillance, and control belief) were emerged on objectified body consciousness, and subjects were divided into 2 groups (objectified group, and non-objectified group) by this variable. Second, male adults were deeply aware of the need of appearance management, and showed the high level of intention to perform appearance management behavior. Third, objectified group showed much more active appearance management behavior than non-objectified group. This results concluded that objectified body consciousness is a very useful variable to understand male adult' appearance management behavior.

The esthetics of chin contour is very important in facial deformities, and the quantity of soft tissue overlying the symphysis can be helpful to the correct diagnosis and surgical treatment for optimal facial harmony. The objectives of this study is to measure the different thicknesses of skeletal and soft tissues of chin on lateral cephalometric radiographs, to obtain the mean values of normal Korean adults, and to investigate the relative proportions of skeletal and soft tissues of chin. The results were as follows ; 1. In normal Korean adults, the relative proportions of the distances of soft tissue toward skeletal tissue were 1.5 in B point and 0.95 in Pg, and there were significant difference between male and female in the relative proportion of Pg (p<0.05). The relative proportion of the distances of vertical soft tissue toward horizontal soft tissue of Me was 1.91, and there were not significant difference between male and female. 2. In normal Korean adults, the distances of skeletal and soft tissues of chin showed no correlation, but the distances of vertical and horizontal soft tissues of Me showed high correlation (p<0.01). 3. In normal Korean adults, the correlations among the distances of each skeletal and soft tissues of chin were significantly high in both of male and female (p<0.01). Among the relative proportions of the distances of skeletal and soft tissues, the correlations of the proportions of B point and Mp and the proportions of Mp and Pg were significantly high (p<0.01).
