Using monthly AVHRR-NDVI composite images, global vector data and statistical information, land cover change patterns in Asia during the major growing season (June, July and August) were analyzed for each country. Specifically, explanations on NDVI changes were developed at a regional scale emphasizing human impacts on ground vegetation. The annual mean change in each country showed NDVI-gain trends in high latitude areas and some parts of eastern China and northern/western India. On the contrary, NDVI-loss trends were distinctive in Japan, Korea, some parts of southeastern China, Vietnam, Laos, Cambodia, Thailand, Myanmar and some parts in southwestern/eastern India. These patterns largely coincided with socio-economic information reflected by human behavior. The NDVI change trends showed significant correlation with forest area changes. Also, a multiple regression model showed that the NDVI change patterns were significantly dependent on the changes in forest area and total population.

Tropical tasar silkworm, Antheraea mylitta is a commercial forest silkworm in India that produces tasar silk, but never experimented in Uttarakhand, a Himalayan state of India. A. mylitta express divergent phenotypic characters under different ecological conditions; so, we studied the effect of seven forest tree species in two rearing seasons on variability in silk gland weight of Daba (bivoltine) ecorace of A. mylitta at Forest Research Institute in Dehra Dun, Uttarakhand during 2012 and 2013. We used two-way completely randomized block factorial design and Post HOC Tukey's HSD test to analyse the collected data and there after carried out multiple regression analysis. Results indicated that silk gland weight differed significantly between rearing seasons (DF=1, F=2333.98, p <0.05), host plants (DF 6, F= 1516.25, p <0.05) and their interactions (DF=6, F=7.10, p <0.05). Higher silk gland weight was found in second rearing season than the first on all the host tree species. Terminalia alata fed A. mylitta larvae showed the highest silk gland weight of 8.03 and 9.47 g in first and second rearing seasons, followed by T. tomentosa (7.19 & 9.01g), T. arjuna (6.8 & 8.08 g) and L. speciosa (6.57 & 7.83 g) fed larvae, respectively. Post HOC Tukey's HSD test indicated that silk gland weight of L. speciosa and T. arjuna fed larvae in both the rearing seasons did not differ significantly. E.I. analysis also confirmed that T. alata, T. tomentosa, T. arjuna and L. speciosa are better in their order of merit than T. bellirica , T. chebula and L. tomentosa. Multiple regression analysis indicates that larval weight gain is a strong predictor (β=1.002, t=346.777, p = <0.05) for the silk gland weight of A. mylitta ; however, larval duration had significant negative regression weight (β=-0.270, t=-8.436, p = <0.05) on mean weight of silk gland.

Objectives : This study was designed to protect effect on atherosclerosis through regulation of low density lipoprotein(LDL) by 70 % ethanol extract Ganoderma lucidum (GL) in LDL receptor knockout mouse (LDLr ko mice) fed Western diet.Methods : The LDLr ko mice were divided into 3 groups ; Control, GL100, and GL300. After grouping, LDLr ko mice were fed Western diet. The GL (100 or 300 mg/kg body weight/day, p.o.) was administered every day for 8 weeks. The body weight and food intake were measured every day. The changes in the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine, triglyceride (TG), total cholesterol (TC), and high-density lipoprotein (HDL) in serum were analyzed after experiment.Results : The LDLr ko mice fed Western diet were increased body weight gain and blood biochemistry parameters such as ALT, AST, TG, TC, and LDL. However GL300 group significantly reduced the body weight. Also TG, TC, and LDL level did not increase. The levels of ALT, AST, HDL were not changed. Also, LDLr ko mice model liver were observed lipid drop, but GL groups did not appear. Futhermore, histological analysis of GL groups aorta tissue were similar to NOR groups.Conclusions : We confirmed that whether GL administration is protect atherosclerosis or not. As the results, blood biochemistry and histological analysis did not changed much in GL administration groups. This study provides scientific evidence that GL protect the atherosclerosis through the reduction of LDL cholesterol. Therefore GL has potential medicine inhibition of atherosclerosis.

Onggi, described as a 'breathing' type of pottery' has significantly influenced the traditional food culture of Korea. It is known that Onggi is an optimal type of storage for fermented foods such as soy sauce, salted seafood, and Kimchi, as air or liquid can penetrate through the body of this material. These foods gain flavor due to the breeding of aerobic bacteria at the beginning of the fermentation process. In this study, Onggi materials from five regions, Gangjin, Yeoju, Ulsan, Yesan, and Jeju, were collected and analyzed to determine their chemical and physical properties before and after sintering. The differences in the raw materials of other mining regions are examined in terms of their chemical and mineralogical compositions, specific surface area, particle size, and particle distribution. Among them, the Gangjin raw material has the greatest mean particle size of $92.29{\mu}m$, as well as the widest particle size distribution. Differences in the levels of $SiO_2$ and $Fe_2O_3$ are shown among Onggi raw materials. However, the crystalline phases formed after sintering are identical, except for the Jeju samples. At all sintering temperatures tested here, Gangjin Onggi showed the greatest porosity, leading to complete air permeation through the body within 90 minutes. These results taken together indicate that air permeation is strongly related to the pore structures in the Onggi body. This is assumed to affect the fermentation behavior.

The main purpose of this paper is to review the research on the border region, especially herein to consider theoretical models critically and then to gain the implication for appropriate analytical framework or rather theoretical model on the basis of the findings. Through the review of various literature, major finding are as follows. First, the term of border or frontier was used in a rather ambiguous way. Second, the early models in the border region research have been developed to explain barrier effects, of which the border was considered to playa role. However, as border regions change from the closed regions to the opened ones, more adequate models have accordingly been developed. Third, there were several attempts to typify border regions and they tend to focus on the issue of regional development of the regions. Fourth, according to the case studies of the border region research, many border regions are not in isolation or peripheral position any more. Rather they are transformed into potentially prosperous regions through the support of authority as well as inter-regional cooperation.

According to the definition of 'native local food', Jeju has combined its regional specialty products with its own cooking method. It has almost four-hundred kinds, which reflects regional specialty and diversity, yet it is not very well-known. Thus, this present study provides basic research information through the investigation of tourist awareness, intention to consume, drawbacks, development necessity and direction of development of Jeju local foods. The survey was conducted with 295 domestic tourists who had visited Jeju in the last 10 years. In response to a question asked about the consciousness of Jeju local foods, 67.8% of respondents chose average, indicating a relatively high cause for concern. Intention to consume averaged 3.26, which was higher than tourist awareness, having an average of 2.60. Furthermore, local food interest and demographic characteristics of respondents were found to have an influence on tourist awareness and intention to consume. 87.8% of respondents answered above average with respect to the drawbacks of Jeju's local foods and development necessity and direction, with the main drawbacks being lack of PR (43.1%) and high price (39.0%). The priority of most respondents was the quality and taste of the food (50.8%). Based on the results of this study, if tourist awareness can be effectively increased, an escalation in intent to consume will follow, naturally promoting the consumption of Jeju's local foods. Consequentially, for tourism commercialization, the quality and taste of the foods have to be improved in addition to the gain in popularity through efficient PR methods.

Purpose: Several morphometric studies have been performed to investigate brain abnormalities in congenitally deaf people. But no report exists concerning structural brain abnormalities in congenitally deaf adolescents. We evaluated the regional volume changes in gray matter (GM) using voxel-based morphometry (VBM) in congenitally deaf adolescents. Materials and Methods: A VBM8 methodology was applied to the T1-weighted magnetic resonance imaging (MRI) scans of eight congenitally deaf adolescents (mean age, 15.6 years) and nine adolescents with normal hearing. All MRI scans were normalized to a template and then segmented, modulated, and smoothed. Smoothed GM data were tested statistically using analysis of covariance (controlled for age, gender, and intracranial cavity volume). Results: The mean values of age, gender, total volumes of GM, and total intracranial volume did not differ between the two groups. In the auditory centers, the left anterior Heschl's gyrus and both inferior colliculi showed decreased regional GM volume in the congenitally deaf adolescents. The GM volumes of the lingual gyri, nuclei accumbens, and left posterior thalamic reticular nucleus in the midbrain were also decreased. Conclusions: The results of the present study suggest that early deprivation of auditory stimulation in congenitally deaf adolescents might have caused significant underdevelopment of the auditory cortex (left Heschl's gyrus), subcortical auditory structures (inferior colliculi), auditory gain controllers (nucleus accumbens and thalamic reticular nucleus), and multisensory integration areas (inferior colliculi and lingual gyri). These defects might be related to the absence of general auditory perception, the auditory gating system of thalamocortical transmission, and failure in the maturation of the auditory-to-limbic connection and the auditorysomatosensory-visual interconnection.

In the glocal era, the competition becomes more intense in regional development centered around cities rather than countries. This suggests that increasing the city's unique charms through a positive city image can allow the city to gain a competitive edge in the competition for regional development. In this background, this study would contribute to improving the positive image of Pyeongtaek City, presenting the value and development direction of the image it would pursue, aiming to develop a promotional design for the improvement of the city image. As the details of the research, this study recognized the city image as an efficient means of public relations of the city from its concept and necessity. Thus, this study conducted a survey on the analysis of status and image of Pyeongtaek City. This study would contribute to improving the positive image of Pyeongtaek City, presenting the results of the development of a promotional design of its administration and a plan for utilization in the manual, proceeding by stages.

Microdeletions of chromosome 22q11.2 are one of the most common microdeletions occurring in humans, and is known to be associated with a wide range of highly variable features. These deletions occur within a cluster of low copy repeats (LCRs) in 22q11.2, referred to as LCR22 A-H. DiGeorge (DGS)/velocardiofacial syndrome is the most prevalent form of a 22q11.2 deletions, caused by mainly proximal deletions between LCR22 A and D. As deletions of distal portion to the DGS deleted regions has been extensively studied, the recurrent distal 22q11.2 microdeletions distinct from DGS has been suggested as several clinical entities according to the various in size and position of the deletions on LCRs. We report a case of long-term follow-up of a female diagnosed with a 22q11.2 distal deletion syndrome, identified a deletion of 1.9 Mb at 22q11.21q11.23 (chr22: 21,798,906-23,653,963) using single nucleotide polymorphism array. This region was categorized as distal deletion type of 22q11.2, involving LCR22 D-F. She was born as a preterm, low birth weight to healthy non-consanguineous Korean parents. She showed developmental delay, growth retardation, dysmorphic facial features, and mild skeletal deformities. The patient underwent a growth hormone administration due to growth impairment without catch-up growth. While a height gain was noted, she had become overweight and was subsequently diagnosed with pre-diabetes. Our case could help broaden the genetic and clinical spectrum of 22q11.2 distal deletions.

In boars, unlike the cases in males of other species, gonadal hormones suppress voluntary feed intake. for this reason, barrows, compared with gilts or boars, eat too much feed resulting in excessive fat deposition. Two experiments were performed in the present study to investigate the effects of implantation of Revalor H[Experiment(Exp.) I: 140mg trenbolone acetate(a synthetic androgen) + 14mg estradiol-$17\beta(E_{2}\beta)$] and Compudose(Exp. II; 24mg $E_{2}\beta$) on growth efficiency, carcass characteristics and circulating concentrations of IGF-I and IGF-binding protein-3(IGFBP-3). In Exp. I, sixty-four cross-bred finishing barrows weighing approximately 60kg were randomly divided into eight pens under a 2[control vs Revalor implant] $\times$ 2(ad libitum vs $80\%$ ad libitum feeding) $\times$2[control($103\%$ NRC-recommended level) vs low-energy($87\%$ NRC recommendation) diet] arrangement of treatments. In Exp. II, effects of Compudose were studied using 80 finishing barrows(10 animals/pen). In both Exps., all the animals were slaughtered at 100- to 110-kg body weight. Both Revalor and Compudose implants caused a decrease in feed intake and backfat thickness without affecting major physicochemical characteristics of the carcass and an increase in circulating IGF-I concentration. Moreover, Revalor implant exhibited greater effects than restricted feeding, low-energy diet, or Compudose in these variables. In addition, Revalor implantation suppressed weight gain, but enhanced the feed efficiency without exhibiting any interaction with the diet or feeding. In summary, results suggest that 1) both androgen and estrogen suppress voluntary feed intake and backfat deposition and enhance IGF-I secretion and 2) these effects of the gonadal steroid hormones in growth are likely to be mediated, in part, by IGF-I in finishing barrows.
