As part of the safety case development for generic disposal sites in Korea, it is necessary to develop generic assessment models using various geosphere–biosphere interfaces (GBIs) and potentially exposed groups (PEGs) that reflect the natural environmental characteristics and the lifestyles of people in Korea. In this study, a unique modeling strategy was developed to systematically construct and select Korean generic biosphere assessment models. The strategy includes three process steps (combination, screening, and experts’ scoring) for the biosphere system conditions. First, various conditions, such as climate, topography, GBIs, and PEGs, were combined in the biosphere system. Second, the combined calculation cases were configured into interrelation matrices to screen out some calculation cases that were highly unlikely or less significant in terms of the exposure dose. Finally, the selected calculation cases were prioritized based on expert judgment by scoring the knowledge, probability, and importance. The results of this study can be implemented in the development of biosphere assessment models for Korean generic sites. It is believed that this systematic methodology for selecting the candidate calculation cases can contribute to increasing the confidence of future site-specific biosphere assessment models.

This study identified single nucleotide polymorphisms (SNPs) that affect the body weight of chickens. Analysis of body weight showed that the Cornish breed had the highest body weight, and the Korean native chicken (Gray Brown) had the lowest body weight. TSH is composed of an α-subunit and a β-subunit, and the TSH-β gene encoding the β-subunit has been reported to be associated with obesity. In chickens, it is located on chromosome 26 and is reported to be associated with growth. The calcium-sensing receptor gene (CaSR) plays a role in the regulation of extracellular calcium homeostasis and is responsible for calcium absorption in the urinary tract, which affects the eggshell quality in poultry. It was shown that TSH-β was strongly correlated with weight in Cornish and Korean native (Gray Brown) chickens, particularly in those with the CC trait. However, CaSR showed no association with body weight in poultry; it was associated with calcium and the eggshell. Thus, selection for TSH-β can be used to produce individuals with more favorable traits in terms of body weight.

Azuki bean beetle (ABB), Callosobruchus chinensis (L.) is a field-to-storage pest of legumes and its female produces sex pheromone with two isomeric components, 2Z-homofarnesal and 2E-homofarnesal. Two day old virgin adults were exposed to 0, 200, 300, 400, 500 & 600 Gy gamma radiation and effect on longevity, fecundity, sterility and pheromone production were studied. Longevity (female; P < 0.001, male; P < 0.001) and fecundity (P < 0.001) were dose-dependently affected by the gamma irradiation. Both adults were totally sterilized by the tested doses of gamma irradiation as depicted by the null hatchability of laid eggs. Gas chromatography-mass spectrometry for solid phase micro extraction revealed that both of the pheromone components were significantly but not completely reduced by 300 Gy. It is a pre-requisite for a successful sterile insect technology that the sterility of ABB is induced without the total disruption of calling behavior.

Azuki bean beetle (ABB), Callosobruchus chinensis (L.) is a field-to-storage pest of legumes. It is ideal to estimate its field population before it invades the stored legume stuffs. The seasonal occurrence was monitored with rocket traps supplied with synthetic female sex pheromone and with sweep netting during 2015-2016. Harvest damage was evaluated by taking purposive samples of the pods at harvest. Over-wintering stage was identified from the pod samples of left over plants. The results ascertained that October was the peak season of ABB in the azuki bean field. Grain damage and weight loss of the harvested azuki bean were 2.7% and 2.4% respectively, which could be the inoculum for storage loss. The adult emergence only from live pupae collected from pods revealed for its most probable over-wintering stage. In all, this study provides insight into some field ecological parameters of ABB that could be helpful in adopting its management strategies.

Plant essential oils (EOs) exhibit an array of biological activities against insect pests. However, their negative influences on the pheromonal activity of azuki bean beetle (ABB), Callosobruchus chinensis L., the field-to-storage pest of legumes, have not received research attentions. We evaluated the effects of three EOs and their two major components on the attractiveness of male ABBS to synthetic homofarnesal (2E- : 2Z-homofarnesal = 6:4) using Y-tube olfactometry in laboratory and rocket traps in the semi-open vinyl house. The tested EOs of Illicium verum, Croton anisatum and Gaultheria fragrantissima as well as the major components, trans-anethole and methyl salicylate ascertained significant negative effect against homofarnesal both in Y-tube olfactometry and in semi-open vinyl house tracing out a new opportunity of integrating them in ABB management programs both in field and storage.

A few importers of marine products has practiced ice glazing of frozen fish and forced water injection into small octopus to increase their weight. These rampant practices have recently become a serious social issue. Therefore, this study was conducted to develop non-destructive detection methods for verifying forced water injected frozen small octopus using dielectric properties. The weight and dielectric properties of live small octopuses imported from China were measured using an electronic scale and dielectric probe connected with vector network analyzer, respectively. The frequency range from 0.5 to 4 GHz was used for measurement of dielectric properties of small octopus samples. The moisture contents of live small octopuses were determined by convection drying at 105°C for 24 h. To increase weight of small octopus samples, each sample was placed in a container including 2% polyphosphate solution of 800 mL and was kept for 24 h in a refrigerator. Then, the sample was removed from the solution and was frozen at -35°C for 24 h. The moisture contents of live small octopuses were 81.6 ± 1.9% (wb). Regardless of weight of live small octopuses, dielectric constant (ε′) and dielectric loss factor (ε′′) were from 76.09 to 58.62 and from 101.95 to 28.72, respectively. The average weight gain of small octopuses immersed in the solution was approximately 40.6%. Dielectric constant (ε′) and dielectric loss factor (ε′′) of forced water injected small were from 78.18 to 66.71 and from 51.96 to 25.05, respectively. In addition, there was a significant difference between dielectric properties and penetration depth of fresh frozen and forced water injected frozen small octopuses. The results clearly showed that dielectric properties of small octopuses affected by moisture contents could be an important factor to detect forced water injected frozen small octopuses.

The education based on synesthesia has been used to be applied for several years. Especially, We focused on the Coloured-hearing Synesthesia for music education for children who have difficulty in practicing pitch by using the serious game based on Coloured-hearing theory. Also, smart platform is flexible for several sort of video games so we expect good accessibility for children. For proving the effectiveness for education by using this technology and theory, we design the serious game for music called “Bunny’s Cave” based on Coloured-hearing theory and conduct the usability test aimed at 3rd grade student in elementary school.

Neurotized melanocytic nevus (NMN) is categorized into intradermal/intramucosal type of acquired melanocytic nevus. In contrast to typical intramucosal nevus which has relatively distinct histological features, the diagnosis of NMN requires more attention due to its mimicry of benign neural tumors such as neurofibroma. The majority of lesional cells, NMN cells, showed a spindle cell morphology and abundant, eosinophilic cytoplasm which were positive for S-100, vimentin, and collagen type IV. Positive reaction for MART-1 was detected in the NMN cells as well as in the epithelioid nevus cells beneath the epithelium. Neurofibroma exhibited diffuse positivity for S-100, vimentin, CD34 and collagen type IV, but never expressed MART-1. Toluidine blue stained the numerous mast cells scattered in the lesion of neurofibroma, compared to the relatively minor detection of mast cells in NMN. Therefore, MART-1 is a useful marker in differentiating NMN from neurofibroma.

Ski protein is implicated in proliferation/differentiation in a variety of cells. We had previously reported that Ski protein is present in granulosa cells of atretic follicles, but not in preovulatory follicles, suggesting that Ski has a role in apoptosis of granulosa cells. The alternative fate of granulosa cells other than apoptosis is to differentiate to luteal cells; however, it is unknown whether Ski is expressed and has a role in granulosa cells undergoing luteinization. Thus, the aim of the present study was to locate Ski protein in the rat ovary during luteinizationto predict the possible role of Ski. In order to examine the expression pattern of Ski protein along with the progress of luteinization, follicular growth was induced by administration of equine chorionic gonadtropin to immature female rats, and luteinization was induced by human chorionic gonadtropin treatment to mimic luteinizing hormone (LH) surge. While no Ski-positive granulosa cells were present in preovulatory follicle, Ski protein expression was induced in response to LH surge, and was maintained after the formation of the corpus luteum (CL). Though Ski protein is absent in granulosa cells of preovulatory follicle, its mRNA (c-Ski)was expressed and the level was unchanged even after LH surge. Taken together, these results demonstrated that Ski protein expression is induced in granulosa cells upon luteinization, and suggests that its expression is regulated post-transcriptionally.

The purpose of this study is to find out how SNS marketing activities affect brand recognition, brand familiarity, and purchase intention for consumers who have purchased products from franchise chicken stores, including whether there is a moderating effect according to gender. SNS marketing activities were set up by configuring three attributes which are, SNS advertising, SNS information, and SNS events as sub-factors. For empirical analysis, a survey was conducted on SNS users, and SPSS/AMOS statistical programs were employed for the data analysis. First, the result of the empirical analysis showed that SNS advertising, SNS information, and SNS events have a significant positive effect on brand recognition. Second, it was found that the SNS events had a significant positive effect on brand familiarity. Third, it was found that SNS advertising has a significant positive effect on purchase intention. Fourth, it was observed that brand recognition has a significant positive effect on brand familiarity. Fifth, it was found that brand recognition and brand familiarity have a significant positive effect on purchase intention. Sixth, it was found that gender plays a significant role in the relationship between these constructs. Therefore, it can be assumed that the hypothesis presented in this study is sufficiently proven.

Sexual dimorphism is the most conspicuous difference between the sexes. This study examines possible sexual dimorphism and the relative growth patterns of morphometric characteristics in the marine medaka, Oryzias dancena for their potential to help differentiate between males and females of this species. The von Bertalanffy growth parameters estimated by a non-linear regression method were L∞=30.2 mm, K=3.22/year, and τ0=-0.05. All 18 characteristics measured showed a difference between males and females from 70 days after hatching. Each of these characteristics were significantly different between sexes (ANCOVA, P<0.05), and the ratio of standard length between sexes showed that males were larger than females for all five morphometric measurements. Fin length measurements were taken for 21 distances of anal fin and 7 distances of dorsal fin between landmarks. There were all differences for all dorsal fin rays between the males and the females and there is significant difference in 70 days after their hatch when the sexual dimorphism is presented. The significant difference (P<0.05) in fin ray for male and female was more greatly seen as they grow. Male marine medaka showed more rapid growth than females, with longer length, dorsal fins and anal fins. Differences in these characteristics will be useful during experiments when it is necessary to differentiate between sexes of marine medaka.

Background : Constipation is can refer to bowel movements that are rare or hard for pass. Constipation is common symptom in current people and the treatment of constipation focused on the use of medicines or physical intervention. The aim of this study are investigates the effects of modified-extracts of Salicornia herbacea (S. herbacea) L. on constipation model. Methods and Results : To investigate the effect of these extracts on constipation model with Sprague-Dawley rats by loperamide administration, we orally administered various dosage of modified-extracts of S. herbacea. L. Then, we checked constipation-related parameters such as fecal number, colon weight, colonic transmit length, colon length as compared to the controls and ameliorated in a dose dependent manner. The results indicated that modified-extracts of S. herbacea. L. was ameliorated constipation in SD rat model. Conclusion : Based on the results, modified-extracts of S. herbacea L. and its many ingredients were considered to have effects on constipation.

The correlation between meteorological data collected at the optical wide-field patrol network (OWL-Net) Station No. 1 and the seeing of satellite optical observation data was analyzed. Meteorological data and satellite optical observation data from June 2014 to November 2015 were analyzed. The analyzed meteorological data were the outdoor air temperature, relative humidity, wind speed, and cloud index data, and the analyzed satellite optical observation data were the seeing full-width at half-maximum (FWHM) data. The annual meteorological pattern for Mongolia was analyzed by collecting meteorological data over four seasons, with data collection beginning after the installation and initial set-up of the OWL-Net Station No. 1 in Mongolia. A comparison of the meteorological data and the seeing of the satellite optical observation data showed that the seeing degrades as the wind strength increases and as the cloud cover decreases. This finding is explained by the bias effect, which is caused by the fact that the number of images taken on the less cloudy days was relatively small. The seeing FWHM showed no clear correlation with either temperature or relative humidity.

Inactive space objects are usually rotating and tumbling as a result of internal or external forces. KOREASAT 1 has been inactive since 2005, and its drift trajectory has been monitored with the optical wide-field patrol network (OWL-Net). However, a quantitative analysis of KOREASAT 1 in regard to the attitude evolution has never been performed. Here, two optical tracking systems were used to acquire raw measurements to analyze the rotation period of two inactive satellites. During the optical campaign in 2013, KOREASAT 1 was observed by a 0.6 m class optical telescope operated by the Korea Astronomy and Space Science Institute (KASI). The rotation period of KOREASAT 1 was analyzed with the light curves from the photometry results. The rotation periods of the low Earth orbit (LEO) satellite ASTRO-H after break-up were detected by OWL-Net on April 7, 2016. We analyzed the magnitude variation of each satellite by differential photometry and made comparisons with the star catalog. The illumination effect caused by the phase angle between the Sun and the target satellite was corrected with the system tool kit (STK) and two line element (TLE) technique. Finally, we determined the rotation period of two inactive satellites on LEO and geostationary Earth orbit (GEO) with light curves from the photometry. The main rotation periods were determined to be 5.2 sec for ASTRO-H and 74 sec for KOREASAT 1.

Several optical monitoring strategies by a ground-based telescope to protect a Geostationary Earth Orbit (GEO) satellite from collisions with close approaching objects were investigated. Geostationary Transfer Orbit (GTO) objects, Inclined GeoSynchronous Orbit (IGSO) objects, and drifted GEO objects forced by natural perturbations are hazardous to operational GEO satellites regarding issues related to close approaches. The status of these objects was analyzed on the basis of their orbital characteristics in Two-Line Element (TLE) data from the Joint Space Operation Center (JSpOC). We confirmed the conjunction probability with all catalogued objects for the domestic operational GEO satellite, Communication, Ocean and Meteorological Satellite (COMS) using the Conjunction Analysis Tools by Analytical Graphics, Inc (AGI). The longitudinal drift rates of GeoSynchronous Orbit (GSO) objects were calculated, with an analytic method and they were confirmed using the Systems Tool Kit by AGI. The required monitoring area was determined from the expected drift duration and inclination of the simulated target. The optical monitoring strategy for the target area was analyzed through the orbit determination accuracy. For this purpose, the close approach of Russian satellite Raduga 1-7 to Korean COMS in 2011 was selected.
