The purposes of this study were to investigate the eating of breakfast by students, the perception of the school breakfast program(SBP), and the operational status of the SBP. The survey was administered to students, parents, and nutrition teachers at practiced and unpracticed middle and high schools in Seoul and Kyunggi-do. The questionnaires were distributed to 46 school dietitians who practiced the SBP, 53 school dietitians who did not practiced the SBP, 2,340 students and 1,360 parents in July, 2007. Eating place and the frequency of breakfast were the significantly between the students of practiced and unpracticed schools. Students, parents, and nutrition teachers had positive perceptions and opinions of the SBP. The advantages of the SBP were the formation of regular dietary habits and saving time for breakfast, whereas complaint factors were menu duplication and taste. Therefore, the results suggest that unpracticed schools should refer to the SBPs case of practiced schools and make an efforts for efficient operation.

${\beta}$-cyclodextrin has an ability to protect compounds from oxidative reaction by collecting them within its ring-like structure. So, In harsh condition ($40^{\circ}C$), marker compound, quercetin, was dramatically reduced in Hovenia dulcis fruit extract containing dextrin at 4 and 8 week compared to 0 week, but not that containing ${\beta}$-cyclodextrin. To evaluate the effects of dextrin and ${\beta}$-cyclodextrin on protective effect of H.dulcis fruit extract against alcohol-induced liver damage, The mice were orally injected alcohol, H. dulcis fruit extract/dextrin (HD) and H. dulcis fruit extract/${\beta}$-cyclodextrin (HCD), respectively, for 7 days. The mice orally administrated with alcohol significantly enhanced the serum concentration of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and the activity of lactate dehydrogenase (LDH) in serum compared to the control group. HD and HCD significantly decreased the levels of serum ALT and AST and serum LDH activities compared to alcohol group. And also alcohol group significantly increased the level of total cholesterol compared to the control group, but HD and HCD significantly reduced it compared to the alcohol group. However, the levels of TG in blood were not significantly changed in all groups. The activities of alcohol dehydrogenase (ADH) were significantly increased in HD and HCD group although those of aldehyde dehydrogenase showed an increasing tendency. This data suggested that HD and HCD were able to induce alcohol degradation in the liver tissues. All together, the results showed that HCD demonstrated their ability to protect liver from alcohol-induced damage on equal terms with HD.

Objectives: We intented to find out the effect of Gami-Eumcheonyijintang to patients who complain with coughing and to make it useful for treating the patients with the symptom. Materials and Methods: We examined the medical of 33 patients who visited with the symptoms of coughing, sputum in Kyungsan University, Hospital of Oriental Medicine from April, 1996 to February, 1999. and we collected the result of the administration with Gami-Eumcheonyijintong. We aimed to find any change in the symptoms, reappearance after recovery, and any special facts with the medicine surveying by telephoning to the patients. Results : the results are as follows, 1. It showed that patients who were under thirties showed higher rate of recovery(75.00%) than who were over thirties(52.94% ). 2, The acute-stage patients who were recovered in less than four weeks showed higher rate of recovery than those chronic-stage patients who were recovered in more than eight weeks. 3. The patients who didn't have the symptoms of sputum or had less serious problems of it with severe coughing showed relatively the highest rate of recovery(73.91% ). 4. The patients who showed the coughing symptom right after URI without any past constitutional history showed the highest rate of recovery(73.68% ). Conclusion : From the above result, we found that Gami-Eumcheonyijintang is more effective in early coughing symptom after URI than chronic stage coughing symptom. It is thought that more studies about medicine composition are needed in the further.

The Albedo MONitor and RAdiometer (AMON-RA) instrument system is designed to measure Earth global albedo anomaly over the wavelength range of 0.3um to 4um. The instrument consists of two interconnecting optical subsystems i.e. a visible channel and an energy channel. The energy channel instrument consists of a modified Winston cone, a couple of relay mirrors and a pyro-electric detector. First, we report the integration and alignment process, leading to the prototype bolometer instrument. We then discuss the radiometric performance characterization including laboratory measurement results and the future plan for further incorporation of the bolometer instrument into the prototype AMON-RA instrument.

This study examined effects of gender role conflicts, academic stress coping ability, and social support on adaptations to college life among male nursing students. Data were collected through self reported structured questionnaire form 225 male nursing students using convenient sampling methods from April 1 to June 4, 2014. Stepwise regression showed that academic stress coping ability had the greatest effect on adaptations to college life(${\beta}=0.33$, p<.001), followed by major satisfaction, social support, gender role conflicts and club activity. These variables together explained 33% of the adaptations to college life in male nursing students(F=23.50, p<.001). Therefore, programs for resolving gender role conflicts and reinforcing academic stress coping ability should be developed. And social support network which consist of professors and the senior-junior nursing students will help to improve adaptability to college life in male nursing students.

With the rapid growth of video data service, demand to provide advertisements or additional information with regard to a particular video scene is increasing. However, the direct use of automated visual analysis or speech recognition on videos virtually has limitations with current level of technology; the metadata of video such as title, category information, or summary does not reflect the content of continuously changing scenes. This work presents a new video contextual advertising system that serves relevant advertisements on a given scene by leveraging the scene's situation information inferred from video scripts. Experimental results show that the use of situation information extracted from scripts leads to better performance and display of more relevant advertisements to the user.

Aporia crataegi, an Korean endangered species, was first analyzed for DNA barcode sequences based on 28-year-old dried specimens and compared barcode characters with 36 individuals of ten geographical populations of Eurasia. They were revealed to consist of five different haplotypes. Among them, haplotype I was mostly extensive and high frequency with 75%. The south Korean individuals were confirmed to be belonging to haplotype I and have no genetic isolation on COI gene. By these results, we consider that selection of the identical haplotype from other geographical populations may be a requirement prior to performing for conservation and restoration of the Korean population. We also propose to analyse the additional genetic markers in order to understand a more accurate genetic structures between haplotypes of this species.

Hip muscle activation and strengthening exercise programs are often used to prevent and treat various lower extremity injuries. Common exercise programs include squat exercises. The purposes of this study were to investigate gluteus medius (GMED) and tensor fasciae latae (TFL) muscle activity, and to assess the GMED/TFL ratio during squat exercises involving different isometric hip contraction conditions. Different types of isometric hip contraction were standard squat without hip contraction, squats with isometric hip adduction, and squats with isometric hip abduction. Twenty (10 males and 10 females) healthy subjects ($23.7{\pm}2.8$ years old) were recruited. Subjects performed the squat exercises with the back supported by a wall and knees flexed to $60^{\circ}$. Surface electromyography (EMG) was used to measure GMED and TFL activity. One-way repeated analysis of variance was used to compare GMED and TFL muscle activity and the GMED/TFL ratio. GMED and TFL EMG activity was significantly higher during squats with isometric hip adduction and abduction compared with the standard squat without hip contraction (p<.05). Between the isometric hip adduction and abduction contraction conditions, only the TFL EMG activity was significantly higher during squats with isometric hip adduction than isometric hip abduction (p<.05). The GMED/TFL ratio was significantly higher during squats with isometric hip adduction than isometric hip abduction (p<.05). Squats with isometric hip adduction and abduction improved GMED and TFL muscle activity. Furthermore, the GMED/TFL ratio was higher during isometric hip adduction than isometric hip abduction. Our data indicate that squat exercises involving isometric hip adduction enhance GMED muscle activity.

A dual-phase ceramic membrane consisting of gadolinium-doped ceria (GDC) as an oxygen ion conducting phase and $MnCo_2O_4$ as an electron conducting phase was fabricated by sintering a GDC and $MnCo_2O_4$ powder mixture. The $MnCo_2O_4$ was found to maintain its spinel structure at temperatures lower than $1200^{\circ}C$. (Mn,Co)(Mn,Co)$O_4$ spinel, manganese and cobalt oxides formed in the sample sintered at $1300^{\circ}C$ in an air atmosphere. XRD analysis revealed that no reaction phases occurred between GDC and $MnCo_2O_4$ at $1200^{\circ}C$. The electrical conductivity did not exhibit a linear relationship with the $MnCo_2O_4$ content in the composite membranes, in accordance with percolation theory. It increased when more than 15 vol% of $MnCo_2O_4$ was added. The oxygen permeation fluxes of the composite membranes increased with increasing $MnCo_2O_4$ content and this can be explained by the increase in electrical conductivity. However, the oxygen permeation flux of the composite membranes appeared to be governed not only by electrical conductivity, but also by the microstructure, such as the grain size of the GDC matrix.
