This study is to provide insights for developing strategies and policy of MICE industry in Korea. Identifying current global statuses, trends, characteristics and analysing the strategic opinions of MICE experts', some strategies and policies were driven, which to activate MICE industry. Compared to Korea, America has comparative advantages in the size and configurations of MICE infrastructure. In order to get competitive edge, Korea needs to utilize various fused contents and stories of K-Series in MICE industry. Unique Venue and MICE destination development, which provide special experiences during the MICE participation, family friendly and children education oriented MICE environment policies are needed. Also, providing fun and Entertainment for MICE participants, demand for 'Green MICE' and medical tourism for the participants should be counted in developing strategic MICE policies.

This study was carried out to investigate diabetic renal changes in cyclophosphamide(CY) treated nonobese diabetic(NOD) mice and to develop animal model of diabetic human nephropathy. The 8-week-old NOD and ICR mice were injected with cyclophosphamide intraperitoneally at 200mg/kg body weight and compared the chemical effects on these mice with the non-treated NOD and ICR mice respectively. The renal glomeruli in ICR, cyclophosphamide-treated ICR(ICR+CY), NOD and cyclophosphamide-treated NOD(NOD+CY) mice were observed by the light and electron microscopes. The results obtained were summarized as follows ; 1. Spontaneous incidences of diabetes mellitus in NOD mice were significantly promoted by dosing with cyclophosphamide. 2. Glomerulohypertrophy, proliferation of mesangium, partial thickening of glomerular basement membrane, and partial fusion of pedicels of podocyte were observed in NOD mice and NOD+CY mice. These changes were not observed in both ICR mice and ICR+CY mice. 3. The diabetic nephropathy observed in NOD+CY mice was more severe than that of non-treated NOD mice.

This project's aim was to determine the reserpine-induced gastric ulcer preventive effect of polysaccharide of Larimichthys crocea swim bladder (PLCSB) in ICR mice. The anti-gastric ulcer effects of polysaccharide of Larimichthys crocea swim bladder was evaluated in mice model using morphological test, serum levels assay, cytokine levels assay, tissue contents analysis, reverse transcription-polymerase chain reaction (RT-PCR) analysis and western bolt assay. High concentration (50 mg/kg dose) of PLCSB reduced IFN-${\gamma}$ as compared to low concentration (25 mg/kg dose) and control mice. SS and VIP serum levels of PLCSB treated mice were higher than those of control mice, and MOT and SP serum levels were lower than control mice. Gastric ulcer inhibitory index of PLCSB treatment groups mice were much lower than control mice, and the high concentration treated mice were similar to the ranitidine treated mice. The SOD and GSH-Px activities of PLCSB treated mice were higher than control mice, close to normal mice and ranitidine treated mice. PLCSB treated mice also showed the similar contents of NO and MDA to normal group. By RT-PCR and western blot assay, PLCSB significantly induced inflammation in tissues of mice by downregulating NF-${\kappa}B$, iNOS, and COX-2, and upregulating $I{\kappa}B-{\alpha}$. These results suggest that PLCSB showed a good gastric ulcer preventive effect as the gastric ulcer drug of ranitidine. Polysaccharide of Larimichthys crocea swim bladder may be used as a drug material from marine products.

The transgenic mice were produced by microinjection of human growth hormone gene fused with mouse metallothionein Ⅰ promoter. They were mated with momal mice by backcross or brother-sister mating. The reproduction efficiencies of female and male n the FO transgenic mice were 17.6%(3/17 mice) and 31.2%(5/16 mice), respectively, and were very lower than that in normal mice(85.7% and 100%, respectively). Interestingly, a few of female transgenic mice were fertile which was different from the previous reports. Of 6 fertile transgenic mice, 2 mice were identified as mosaic type by the reduced frequency of genetic transmission to successive generation below Mendelian levle and the enhanced copy numbers of transgene in progeny mice compared with the transgenic parent. In the group of F1, F2, F3 transgenic mice the reproduction efficiencies of males were gradually improved, whereas females were absolutely infertile. It was consequently shown that the transgenic mice expressing human growth hormone gene were frequently infertile, but the genotypic and phenotypic characteristics of the fertile transgenic mice were normally passed on to the progeny through herm line. Therefore it must be considered wheter or not the products of foreign DNA introduced into animals will detrimentally affect their physiological aspects.

The main purpose of this study is to empirically investigate determinants affecting MICE quality, which then affects to loyalty. In particular, this study focuses on variables in the exhibition and event experiences of the MICE participants. The proposed research includes four variables representing the exhibitions and event experiences (affective, intellectual, behavioral, relational experience), two MICE qualities (commitment, satisfaction), and MICE loyalty. The results of this study reveal that four proposed variables (affective, intellectual, behavioral and relational experience) have a positive impact on two MICE qualities (commitment and satisfaction). Furthermore, the study found that commitment and satisfaction positively influence MICE loyalty. The findings of the study would provide theoretical and practical implications of exhibition and event experiences, quality and loyalty of MICE.

The purpose of this study was to investigate the effects of dietary zinc on immune response in mice. Weanling male mice was placed individually in stainless steel cages and fed a zinc dificient diet and control diet. All mice were given deionized water ad libitum. The introduction of extraneous zinc was minimized in all cage by washing feed jars and water bottles sequentially with 4mM EDTA and conc-nitiric acid followed by deionized water. After 4 and 5 weeks of the diets, mice were immunized with lx 106 Naegleria fowleri intraperitoneally. Mice were weighed once a week. The results from this study are summarized as followed ; 1) Mice fed the zinc dificient diet showed growth retardation. After 3 weeks of diets, mean body weight of zinc deficient mice was 21.4g and that of control was 25.0g. This difference is singnificant statistically (p<0.01). The more time passed, the more remarkable difference was found. 2) The weigth of organs were measured on liver, kidney, spleen, thymus, heart, lung, brain. Difference in weight were observed only in liver and spleen. 3) Proliferative response of spleen cells of zinc deficient mice to con A was lower than that of control mice after one week on immunization(p<0.005). 4) Stimulation index was lower in zinc deficient mice to phytohemagglutinin after two weeks on immunization (p<0.05). 5) Blastogenesis of speen cells of zinc deficient mice to Naegleria fowleric lysate was lower after 10 days on immunization (p<0.05). 6) Immunoglobulin G antribody titers of zinc deficient mice sera by ELISA was lowered to control mice after 5 weeks on immunization (p<0.005).

A humanized mice (hu-mice) model is extremely valuable to verify human cell activity in vivo condition and is regarded as an important tool in examining multimodal therapies and drug screening in tumor biology. Moreover, hu-mice models that simply received human $CD34^+$ blood cells and tissue transplants are also overwhelmingly useful in immunology and stem cell biology. Because generated hu-mice harboring a human immune system have displayed phenotype of human $CD45^+$ hematopoietic cells and when played partly with functional immune network, it could be used to evaluate human cell properties in vivo. Although the hu-mice model does not completely recapitulate human condition, it is a key methodological factor in studying human hematological malignancies with impaired immune cells. Also, an advanced humanized leukemic mice (hu-leukemic-mice) model has been developed by improving immunodeficient mice. In this review, we briefly described the history of development on immunodeficient SCID strain mice for hu-and hu-leukemic-mice model for immunologic and tumor microenviromental study while inferring the potential benefits of hu-leukemic-mice in cancer biology.

The purpose of this study was to detect cell death in the liver of mice treated with thioacetamide (TAA) using fluorescence bioimaging and compare this outcome with that using conventional histopathological examination. At 6 weeks of age, 24 mice were randomly divided into three groups: group 1 (G1), control group; group 2 (G2), fluorescence probe control group; group 3 (G3), TAA-treated group. G3 mice were treated with TAA. Twenty-two hours after TAA treatment, G2 and G3 mice were treated with Annexin-Vivo 750. Fluorescence in vivo bioimaging was performed by fluorescence molecular tomography at two hours after Annexin-Vivo 750 treatment, and fluorescence ex vivo bioimaging of the liver was performed. Liver damage was validated by histopathological examination. In vivo bioimaging showed that the fluorescence intensity was increased in the right upper part of G3 mice compared with that in G2 mice, whereas G1 mice showed no signal. Additionally ex vivo bioimaging showed that the fluorescence intensity was significantly increased in the livers of G3 mice compared with those in G1 or G2 mice (p < 0.05). Histopathological examination of the liver showed no cell death in G1 and G2 mice. However, in G3 mice, there was destruction of hepatocytes and increased cell death. Terminal deoxynucleotidyl transferase dUTP nick end labeling staining confirmed many cell death features in the liver of G3 mice, whereas no pathological findings were observed in the liver of G1 and G2 mice. Taken together, fluorescence bioimaging in this study showed the detection of cell death and made it possible to quantify the level of cell death in male mice. The outcome was correlated with conventional biomedical examination. As it was difficult to differentiate histological location by fluorescent bioimaging, it is necessary to develop specific fluorescent dyes for monitoring hepatic disease progression and to exploit new bioimaging techniques without dye-labeling.
