Various types of industry, from manufacturing industry to service industry, can be a subject of exhibition. So, subdivided studies about exhibition for each type of industry or field are necessary. However, there are still insufficient studies about them. Also, fashion industry related exhibitions should be classified differently from other industries' exhibitions because of their special features. Therefore, this study examines that how an exhibition is utilized as a promotion means of a company and the present condition of a fashion exhibition. It also compares a fashion exhibition with other industrial exhibitions to suggest the effective operations and the progressive promotion of the fashion exhibition. This study uses questionnaire from 140 companies for 5 exhibitions, which participated fashion related exhibitions. Data of this study is statistically analyzed using SPSS for window ver. 10.0 program. It also uses frequency, cross tabs, paired t-test, Independent Samples t-test. As a result of this study, fashion related companies' recognition of exhibitions has been increased. However; in terms of exhibition participation, attitudes such as pre-promotion or pre-education for the staff, who are in charge of the exhibition booths, and the outcome of the exhibition aren't maximized because the right understanding concerning exhibitions is lacking and long-term preparation is insufficient. Also, advertisement for the exhibitions isn't enough because of insufficient preparation and absence of pre-promotion, so consultation with promising buyers can't be activated. Even though there are consultations, the consultations don't have much effect.

Objective: This study is to provide a foundation for developing comprehensive ergonomic design guidelines for in-vehicle information systems (IVIS) by giving an overview of existing researches as well as setting further research directions. Background: The drivers get much more information recently while interacting with new safety functions of the cars. To avoid cognitive overload of the drivers, IVIS should be deigned appropriately by considering various human factors and task conditions. Method: We gathered, analyzed, and summarized ergonomic researches concerned with IVIS design conducted inside and outside Korea according to a categorization system proposed in the study. Frequency analysis was conducted for figuring out what kind of issues took major part of the researches, and their trends across time and regions. Results: Compared to domestic researches, those done in overseas tend to deal with more variety of independent, dependent and extraneous variables. The overseas researches also showed a tendency to get ahead in making ergonomic guidelines for IVIS design by adapting and integrating the results from previous researches. Conclusion and Application: There have been many researches regarding with ergonomic IVIS design, but some of their results became old-fashioned as the technology evolved. Not many researches have considered diverse human factors regarding the drivers' characteristics except age and gender. It is expected that researchers and designers take advantage of this study to find and review relevant results and set out issues of their own for more progressive researches of the field.
The news media report the pledges of presidential candidates, which have important implications for political communication. This study is to investigate the difference between news coverage on the presidential candidate' s pledge and to discuss its implications. The sampled news from the two newspapers were analyzed for content analysis. Frequency analysis and Chi-square analysis are utilized with SPSS. As results, there was no difference in the tone of the article's headlines, but the difference of the tone between the article content was statistically significant. The results means that the media framing affect on the reader's perception. Follow - up study can be suggested a comparative study of past election candidates 'pledge reports, a network analysis for the news language, and a comparative analysis of newspaper coverage and broadcast coverage.
An attempt to clarify the landscape structure of urban areas was carried out in the greenbelt around Seoul, Korea's metropolis. By means of aerial photographs and a field survey, a vegetation map including land-use pattern was made. Landscape structure was described by analyzing this vegetation map and the results of phytosociological survey. Landscape element types identified were (1) secondary forest, (2) plantation, (3) cultivated field, (4) urbanized area, (5) graveyard, and (6) bare rock. Vegetation units, resulting from the phytosociological analysis, included Quercus mongolica, Q. variabilis, Q. acutissima, Pinus densiflora, Q. aliena, and Alnus japonica communities. Plantations were composed of Robinia pseudoacacia, Populus tomentiglandulosa, P. rigida, Larix leptolepis, P. koraiensis, and Castanea crenata stands. Patches near to human settlements in the lower zones of the mountains were fragmented and small but they became larger towards the higher mountain zones. On the other hand, the number of patches was fewer and their size was larger in Mt. Cheonggye more distant from the principal residential area, larger in size, and higher in elevation compared with the other 2 mountains, Mt. Daemo and Mt. Acha. Floristic composition of Mongolian oak(Q. mongolica) stand distributing in the upper part of each mountain, in which artificial interference is rare, showed a difference among those study areas different in parent rock and disturbance regime. But that of black locust(R. pseudoacacia) stand located in lowland of mountainous area, in which artificial interference is frequent was similar to each other. As the results of analyses on the frequency distribution of diameter classes of major species, dominant landscape elements, Mongolian oak forest showed different responses depending on artificial interference as continuous maintenance and retrogressive succession in the sites far from and near to the residential areas, respectively. On the other hand, black locust stands showed a probability to be restore to the native oak forest through progressive succession.
Objective : Moyamoya disease (MMD) is an uncommon cerebrovascular disorder, characterized by progressive occlusion at the terminal portion of the internal carotid artery. Incidence of the disease is high in East Asia and familial MMD accounts for about 15% of the disease. Although the pathogenesis is unknown, association of HLA class I or II alleles with MMD has been reported with conflicting results. We investigated whether there is a difference in HLA class II association between familial and non-familial forms of the disease. Methods : A total of 70 Korean children with MMD, including 16 familial cases (10 probands), and 207 healthy controls were studied. Among familial cases, only 10 probands were used for the HLA frequency analysis. High resolution HLA-DRB1 and DQB1 genotyping was performed using polymerase chain reaction (PCR)-sequence specific oligonucleotide hybridization and PCR-single strand conformation polymorphism methods. Results : The phenotype frequencies of HLA-DRB1*1302 (70.0%) and DQB1*0609 (40.0%) were significantly increased in familial MMD compared to both controls [vs. 15.5%, corrected p ($p_c$) = 0.008, odds ratio (OR) = 12.76; vs. 4.3%, $p_c\;=\;0.02$, OR = 14.67] and non-familial MMD patients (vs. 14.8%, $p_c\;=\;0.02$, OR = 13.42; vs. 1.9%, $p_c\;=\;0.02$, OR = 35.33). The frequencies of DRB1 and DQB1 alleles in non-familial MMD patients were not significantly different from those in controls. Conclusion : Our findings suggest that the genetic polymorphism of HLA class II genes or other closely linked disease relevant gene(s) could be a genetic predisposing factor for familial MMD.

This review paper serves to describe the composition and activity of biological activated carbon (BAC) biofilm which is considered as a progressive process for water treatment. As well as several physical-chemical, biochemical and microbiological analysis methods for characterizing the composition and activity of BAC biofilm, the ability of the biofilm to remove and biodegrade organic matters and pollutants related to other water treatment processes such as pre-ozonation will be reviewed. In this paper, conversion of GAC into BAC, removal mechanism of pollutants, characteristics and affecting factors of BAC biofilm, and modeling of BAC are described in detail. In addition, strategies to control the growth of the BAC biofilm, such as varying the nutrient loading rate, altering the frequency of BAC filter backwashing and applying oxidative disinfection, will be dwelled on related to their respective process control challenges.
Two cytosol malate dehydrogenase allelomorphs are found in the Dark Chub, Zacco temmincki, a freshwater fish inhabiting Korean waters. Mdh-1MM(hereafter referred to as A-type) is distributed along the south and southeastern parts of Korea, whereas the B-type(Mdh-1MS) is found everywhere except the southeast. Several syrnpatric populations can be found in the southern areas with no hybridization between them. The pattern of geographic distribution would indicate that A-type is superior adaptation to colder water temperature; this is collaborated by evidence collected from a sympatric length of the Tongchon stream, Namhae. The relative warmth of the water along this portion of the stream's length was determined its altitude and the time of year. Frequency of B-types found was directly proportional to the relative warmth of the water and inversely proportional to the nurnber of A-types found in the sarne station. Current data tends to suggest that the B-type of Zacco temrnincki first differentiated from Zacco platypus approximately one million years ago (Yang et al., 1984) while A-type subsequently branched from B-type 300,000 years later(Yang and Mm, 1987) through a progressive adaptation toward colder temperature.

Background: Skin self-examination (SSE) may facilitate early diagnosis of melanoma at a potentially curable stage. Little data are available concerning the SSE frequency and knowledge about the symptoms of melanoma in non-patient populations. The aim of our study was to assess the performance of skin self-examination, recognition of potential melanoma symptoms as well as behavior related to sun exposure among web users in Poland. Materials and Methods: A cross-sectional study was conducted among readers of a scientific portal. Invited respondents were asked to complete an online questionnaire. Finally, statistical analysis was conducted on 4,919 surveys towards potential clinical signs of melanoma and SSE performance. Results: Approximately 60% of respondents had ever performed SSE in their life. Only 18.4 % declared performance on a regular, monthly, basis. Factors promoting this activity were established to be bigger place of residence, higher education and sensitive skin phototype, higher level of knowledge concerning melanoma, safe tanning rules and, especially, past surgical excision of naevi. Declared longer use of tanning beds was linked to understanding better the importance of clinical features of melanoma. Awareness of hazardous behavior during sunbathing is associated with the attempts to change them. Conclusions: Regular SSE is not a common practice, whilst the knowledge about the clinical features of melanoma is varied. Therefore, constant pressure should be put on promotion of regular skin self-examination and teaching its proper techniques, including familiarity with the ABCD (asymmetry; border; color; diameter) rule and its extension of "EFG" (elevated, firm, progressive growth) criteria.
Cryopreservation protocols induce partially irreversible damage to mammalian sperm plasma membranes. Previous studies have indicated that adding cholesterol to the plasma membrane, as cholesterol-loaded-cyclodextrins, improves cryosurvival of sperm. Therefore, the purpose of this study was to determine if treating sperm of Markhoz bucks with cholesterol-loaded-cyclodextrins (CLC) (0, 0.75, 1.5, 2.25 and 3 mg/ml diluted $240{\times}10^6$ sperm/ml) in Tris-citric acid-glucose diluents with and without egg yolk (containing 5% glycerol) would improve the post-thaw sperm quality. The motion characteristics were evaluated with a Computer Assisted System Analyzer (CASA); acrosome integrity and vitality were measured with the triple-stain technique. Samples were recovered before and after freezing by means of putting straws into $37^{\circ}C$ water for 30 sec and then parameters were assessed. The results showed that the treatments significantly affected motility, progressive motility, recovery rate, curvilinear velocity, beat cross frequency, live sperm with reacted acrosome, live sperm with unreacted acrosome, dead sperm with reacted acrosorne, and dead sperm with unreacted acrosome during freezing (p<0.05). However; no significant differences were found for average path velocity, straight line velocity, amplitude of lateral head displacement, straightness and linearity (p>0.05). The best results were observed for extender containing 2.25 mg/ml ($240{\times}10^6$ sperm/ml) CLC supplemented with 2.6% egg yolk. In conclusion, the findings of this study indicate improved Markhoz sperm viability and motility following treatment in the presence of egg yolk.

Objective: The aim of study was to investigate the effects of season and single layer centrifugation (SLC) before cryopreservation on post-thaw bull sperm quality in Thailand. Methods: Semen was collected from 6 bulls (Bos indicus) in summer, rainy season and winter 2014 through 2016. Semen characteristics, sperm morphology, sperm kinematics, viability, chromatin structure and mitochondrial membrane were evaluated. Meteorological data were available from the local meteorological station; Results: Season had an effect on semen characteristics in the raw ejaculate, with higher proportions of normal spermatozoa and lower abnormalities in winter than in the other two seasons. Sperm kinematics, viability, DNA fragmentation index, and mitochondrial membrane potential were not different between seasons. Sperm samples selected by SLC had greater normal morphology and a lower proportion with bent tails than controls and higher values of progressive motility (PRO), beat cross frequency, linearity, straightness, wobble (WOB), and lower values of slow motility, velocity average path (VAP), velocity curved line, and amplitude of lateral head displacement than controls. In addition, SLC-selection had a favorable effect on PRO, VAP, and WOB that differed among seasons. Conclusion: Our results suggested that these bulls were well adapted to their location, with season having an effect on sperm morphology. Moreover, SLC could be used prior to cryopreservation, regardless of season, to enhance normal morphology and kinematics of bull sperm samples without adversely affecting other parameters of sperm quality. However, there was considerable variation among bulls in DNA fragmentation index, mitochondrial membrane potential and sperm viability. In addition, SLC had a positive effect on sperm morphology and sperm kinematics, which could be expected to influence fertility.
