Hwang,Kyu-sung,Baik,Yu-kyung,Moon,Hye-young 세계문화관광학회 2007 Conference Proceedings Vol.8 No.0

As the products of mass media, such as drama, movies, and commercial advertisements have grown and entertained us, they induced people to visit the locations where they were filmed. However, little has been known what effects in movies or television-induced locations on tourism. The purpose of this study is to investigate the effects of the products of mass media on tourism through locations induced by dramas, movies, and commercial advertisements. More specially, this study examined the relationships between the perceptions of movies or television-induced affective response, the perceptions of movies or television-induced attributes and movies or television-induced destination images on tourism. Findings suggest that if audiences enjoy delightful movies, they will feel destination images with fun and delightfulness when they visit the location scene. Also, the results suggest that if dramas and movies gain in public favor, the location where they are filmed will become a new and fantastic destination to people.

Polychlorinated biphenyls (PCBs) are widespread environmental contaminants and have become distributed throughout the entire ecosystem. Human populations have been exposed to these chemicals by both chronic and acute exposures, Apoptosis is a programmed cell death mechanism to control cell number in tissue and to eliminate individual cells that may lead to disease states. The present study was designed to investigate whether 2,2´,5,5´-Tetrachlorobiphenyl increase the production of active oxidants, and subsequently promotes apoptosis of neuronal SK-N-MC cells. Upon treatments with 2,2´,5,5´-Tetrachlorobiphenyl, the time- and concentration-dependent inhibition of cell viability were observed. The capability of 2,2´,5,5´-Tetrachlorobiphenyl to induce apoptosis was associated with proteolytic cleavage of specific target proteins such as poly (ADP-ribose) polymerase and beta-catenin proteins suggesting the possible involvement of caspases. This study examined the association of PCB-induced apoptosis with the modulation of biomakers of oxidative damage to lipids (malondialdehyde [MDA]) in SK-N-MC cells treated with 2,2,5,5-Tetrachlorobiphenyl (5, 10, 15, 20㎍/㎖) for 12 and 24hrs. Increased MDA was observed in cytosol treated with 10, 15, 20/㎍/㎖ for 12 hrs and in media treated with 10, 15, 20㎍/㎖ for 24 hrs. The activities of antioxidant enzymes, catalase, Cuzn--Superoxide Dismutase, and Glutathione S-Transferase, were also examined.

Hwang, Hyunmin,Joo, Piljae,Kang, Moon Sung,Ahn, Gukmoon,Han, Joong Tark,Kim, Byeong-Su,Cho, Jeong Ho American Chemical Society 2012 ACS NANO Vol.6 No.3

<P>We demonstrate a controlled, systematic method to tune the charge transport in graphene field-effect transistors based on alternating layer-by-layer assembly of positively and negatively charged graphene oxide followed by thermal reduction. Surprisingly, tuning the number of bilayers of thermally reduced graphene oxide multilayer films allowed achieving either ambipolar or unipolar (both n- and p-type) transport In graphene transistors. On the basis of X-ray photoemission spectroscopy, Raman spectroscopy, time-of-flight secondary ion mass spectrometry, and temperature-dependent charge transport measurements, we found that nitrogen atoms from the functional groups of positively charged graphene oxide are incorporated Into the reduced graphene oxide films and substitute carbon atoms during the thermal reduction. This nitrogen-doping process occurs in different degrees for graphene multilayers with varying numbers of bilayers and thereby results in the interesting transition in the electrical behavior In graphene multilayer transistors. We believe that such a versatile method to control the charge transport in graphene muttilayers will further promote their applications in solution-processable electronic devices based on graphene.</P>

Backgrounds/Aims: Gallbladder carcinoma (GBCa) T2 lesions are considered to be advanced tumors showing diverse features in tumor extent. When this T2 lesion does not involve the cystic duct and there is no evidence of lymph node metastasis, we have to consider what is the most reasonable extent of resection - that is, whether to perform concurrent extra-hepatic bile duct resection (EHBD) resection or not. This study intends to evaluate the adequacy of EHBD resection in patients undergoing resection for T2N0 GBCa. Methods: From our institutional database of GBCa, 48 cases of T2N0 GBCa who underwent R0 resection during November 1995 and August 2008 were selected. Patients who underwent prior laparoscopic cholecystectomy were excluded. Their medical records were reviewed retrospectively. Results: Their mean age was 63.2±83.3 years and females were 25. The mean serum CA19-9 level was 37.3±89.3 ng/ml. The extents of liver resection were wedge resection (n=36) and segment 4a+5 resection (n=12). Concurrent EHBD resection was performed in 16 (33.3%) patients. No fatal surgical complication occurred. The majority of tumor pathology was adenocarcinoma (n=42), with additional unusual types as papillary (n=3), saromatoid (n=1), signet ring cell (n=1) and adenosquamous (n=1) cancers. The overall survival rate was 87.1% at 1 year, 69.5% at 3 years and 61.7% at 5 years. After exclusion of mortalities not related to cancer, the overall patient survival rate was 89.6% at 1 year, 72.9% at 3 years and 64.7% at 5 years, with 3-year survival rates of 72% in the EHBD resection group and 69.2% in the non-resection group (p=0.661). Conclusions: The results of this study indicate that concurrent EHBD resection did not improve patient survival when R0 resection was achieved in patients with T2N0 GBCa. Therefore, routine EHBD resection may not be indicated for T2N0 GBCa unless the tumor is close to the cystic duct. (Korean J Hepatobiliary Pancreat Surg 2012;16:142-146)

Moon-Tae Song,Jeom-Ho Lee,Sang-Bok Lee,Ja-Hwan Ku,Youn-Sang Cho,Myung-Hee Song,Sung-Ho Choi,Hung-Goo Hwang 韓國作物學會 2003 Korean journal of crop science Vol.48 No.1

If a quantitative trait loci (QTL) marker identified in a population is applicable to different populations (marker universality), this will not only reduce the labor and cost in marker assisted selection (MAS), but accelerate the application of molecular markers to real breeding programs. Present study aims to evaluate the defined QTL related markers from a population to a different breeding population for the MAS. Four rice breeding populations were subjected to seventy-five simple sequence repeat (SSR) markers which were already identified for their polymorphism information content (PIC) in the parents of the crossings. Among them, eight markers were evaluated for their correlation between presence of marker alleles and phenotypic expression in breeding populations. A reasonable level of polymorphism for the mapped markers originated from any sources of rice accessions was observed between crosses of any sources (marker repeatability). However, correlation between presence of markers and expression of the traits in rice breeding populations was not significant except for minor portion of traits and markers examined (failure of marker universality). In the present study, various strategies were discussed to develop new markers with universality of breeding application.

2,2',5,5'-Tetrachlorobiphenyl Mediates Oxidative Stress-Induced Neuronal Apoptosis in Neuronal SK-N-MC Cells

Hwang,Sang Gu,Lee,Hyung Chul,Lee,Ji Young,Kim,Jae Won,Chung,Yeon Gu,Lee,Bo Ram,Kim,Yong Hoon,Choi,Young Keun,Joo,Woo Hong,Cho,Yong Kweon,Moon,Ja Young 한국생명과학회 2001 한국생명과학회 학술발표회 Vol.33 No.-

Polychlorinated biphenyls (PCBs) are ubiquitous environmental contaminants, some of which may be neurotoxic. The goal of this study was to determine if exposure to 2,2´,5,5´-Tetrachlorobiphenyl (PCB 52) leads to an induction of oxidative stress, and subsequently promotes apoptosis of neuronal SK-N-MC cells. Upon treatments with PCB 52, the time- and concentration-dependent inhibitions of cell viability were observed. The capability of PCB 52 to induce apoptosis was associated with proteolytic cleavage of specific target proteins, poly (ADP-ribose) polymerase and -catenin, suggesting the possible involvement of caspases. Reactive oxygen species (ROS) formation was examined in SK-N-MC cells after treatment of PCB 52 by concentrations (5, 10, 15, and 20 μg/㎖) and incubation times (15, 30, 45, 60, 75, 90, and 120 min), respectively. It showed that the rate of ROS production in the cells was increased in a does-dependent manner to 45 min, followed by a return towards control levels after 120 min treatment, ROS formation was also measured in the presence of superoxide dismutase (inhibitor of oxygen free radical production) or mannitol (hydroxyl radical scavenger). Both the ROS scavengers exhibited significant inhibition effects of ROS generation in PCB 52-treated group, but mannitol had stronger scavenging effect of the ROS generated by PCB52 than superoxide dismutase had. We examined the association of PCB-induced apoptosis with the modulation of biomarkers of oxidative damage to lipids (malondialdehyde [MDA]) in SK-N-MC cells. Increased MDA was observed in cytosol treated with 10, 15, and 20 μg/㎖ of PCB 52 for 12 h. The activities of antioxidant enzymes, catalase, Cu/Zn-Superoxide Dismutase (Cu/Zn-SOD), were also examined. The neuronal cells showed a sustained increase in Cu/Zn-SOD activity with increasing concentrations of PCB 52. When treated with 10 μg/㎖ of PCB 52 for 24 h, the cells had a two-fold greater rate of change in catalase activity when compared to control group. These results suggest that PCB 52 induces

The goal of this study is to investigate bending properties of domestic timber. Three representative structural timber from Larix kaempferi, Pinus koraiensis, and Pinus densiflora, in the northeastern South Korea were selected. Visual grading for the timber was conducted based on KFRI notification 2009-01 and the bending strength for the timber was evaluated based on ASTM D 198 bending. The high percentage of grade 1 and 2 for Larix kaempferi shows that the KFRI notification was optimized for this species. The bending strength distributions from Pinus koraiensis and Pinus densflora were very similar. It could be possible to specify the allowable bending properties of these two Specification using a united species group similar to spruce-pine-fir. Lastly, the bending strength of 120 × 180 mm structural members was higher than both existing values in KBC 2009 and design values for timber of imported species described in the NDS. Thus, 120 mm thick domestic sofiwoods could replace the commercial imported species and the KBC should be modified to provide design values for both timber and dimensional lumber, respectively, like NDS.
