  • The purpose of this study was to analyze the psychosocial changing process of upper grade students expelled from local private university. For this purpose, interview were conducted with 15 students. The collected data were analyzed using a Grounded Theory. As a result, 183 concepts, 54 sub categories, and 18 essential categories were derived. The results of the process analysis showed that the process of psychosocial changing is composed of seven steps Find a sense of belonging', 'Find fun', 'Stop thinking', 'Experience the (outside) world', 'Career decision', 'Immersion', 'Finish the course'. The results of this study were compared with previous researches, and the newly discovered points and future research topics and points to be considered in local private university field were discussed.

  • This study aimed to evaluate the anti-obesity effects of Cudrania tricuspidata leaf extract in the order of leaf development on the shoot (L0, L1, L2, L3, L4, and L5). The leaves at the apex of a Cudrania tricuspidata shoot were classified as L0; the next leaves of the apex were classified as L1, L2, L3, and L4 from highest to lowest; and the lowest leaf was classified as L5. A series of 70% ethyl alcohol leaf extracts were screened for the inhibitory effects of adipogenesis in 3T3-L1 preadipocytes. We found that the apical leaf extract of Cudrania tricuspidata (CTL0) was the most effective. Next, a study was conducted on the inhibitory action mechanism of CTL0. Treatment with CTL0 significantly suppressed the differentiation of 3T3-L1 preadipocytes in a dose-dependent manner, as confirmed by the decrease in lipid droplet content observed with Oil Red O staining. Treatment with 12.5 ㎍/ml, 25 ㎍/ml, and 50 ㎍/ml of CTL0 significantly reduced the lipid droplet content. Glucose and cellular triglyceride concentrations were reduced in the 3T3-L1 cells on the CTL0-treated medium compared to the differentiation medium (DM control, DMEM + insulin + dexamethasone + rosiglitazone). Compared with DM, CTL0 significantly inhibited the expression of key pro-adipogenic transcription factors, including peroxisome proliferator-activated receptor γ (PPARγ), LPL, A-FABP, and Glut4. These findings show that CTL0 extract has potent anti-obesity effects.

  • Owing to increased interest in preventing obesity in an aging society, both men and women spend considerable amount of cost on obesity managements. In this study, we investigated the natural substances on anti-obesity activities in 3T3-L1 pre-adipocytes. Also, to improve anti-obesityeffects, research using 3T3-L1 pre-adipocytes cells is crucial. The anti-obesity effect of 70% ethanol extract from Torilis Japonica Decandolle on the differentiation of 3T3-L1 pre-adipocytes to adipocytes was investigated by suppressing adipocyte differentiation and lipid accumulation with Oil Red O assay, and western blot analysis. Compared to the control, 70% ethanol extract of Torilis Japonica Decandolle was significantly inhibited adipocyte differentiation and intracellular triglyceride (TG) level at a concentration of $100{\mu}g/ml$. To determine the mechanism of reduction in TG content, we determined the level of protein expression of obesity-related proteins, such as peroxisome-proliferatorsactivated-receptor-${\gamma}$ ($PPAR{\gamma}$) and CCAAT enhancer-binding-proteins-${\alpha}$ ($C/EBP{\alpha}$), and Acetyl-CoA carboxylase (ACC) phosphorylation. As a results, 70% ethanol extract of Torilis Japonica Decandolle significantly decreased protein expression of $PPAR{\gamma}$, $C/EBP{\alpha}$ and ACC phosphorylation. These results indicate that 70% ethanol extract of Torilis Japonica Decandolle is the most effective candidate for preventing obesity. However further studies will be needed to identify the active compounds that confer the anti-obesity activity of Torilis Japonica Decandolle.

  • Purpose: Type 2 diabetes mellitus is a metabolic condition marked by persistent elevated blood sugar levels resulting from insulin resistance. The effective management of diabetes mellitus involves strict regulation of the blood glucose levels. This study examined the effects of Autumn olive (Elaeagnus umbellata Thunb.) berry (AOB) on insulin resistance and hyperglycemia using a type 2 diabetes mellitus animal model. Methods: Eight-week-old C57BL/6J mice were divided into four groups. The control group received a basal diet, while the high-fat, high-sucrose (HFHS) group was fed a HFHS diet containing 27% sucrose and 33% lard for 12 weeks. The low AOB (LAOB) and high AOB (HAOB) groups were offered a HFHS diet with a 0.5% and 1.0% AOB extract, respectively. Results: The HAOB group showed significantly lower epididymal fat pad weight than the HFHS group. The LAOB and HAOB groups showed lower serum glucose levels and homeostasis model assessment for insulin resistance values than the HFHS group, and the HAOB group has lower serum insulin levels than the HFHS group. Supplementation with HAOB decreased serum cholesterol levels significantly compared with the HFHS group. The consumption of LAOB and HAOB reduced the serum triglyceride and hepatic total lipids and triglyceride levels compared to the HFHS group. In addition, LAOB and HAOB consumption in mice fed a HFHS diet increased adenosine monophosphate-activated protein kinase protein expression. Insulin receptor substrate-2 protein expression in the HAOB group was significantly higher than the HFHS group. Conclusion: AOB can alleviate hyperglycemia in type 2 diabetes mellitus partly by mitigating insulin resistance.

  • Local management trade ports are small-sized trade ports, which require active operation to strengthen the local cities' economic power and enhance the local industries' added value. In addition, local management trade ports should berth ships larger than the existing ships to increase efficiency and keep up with the international trend where ships are becoming larger. Furthermore, they should also prepare operating standards. This study selected Okgye Port among local management trade ports. We performed a mooring safety simulation evaluation according to the scenario where a 50,000 DWT vessel is moored at the current 20,000 DWT class pier. The emergency departure criteria were 27kts at 3.2s of wave period and 22kts at 5.0s of wave period at the existing pier. Results showed that mooring limit condition increased by about 50% to 41kts at 3.2s of wave period and 36kts at 5.0s of wave period. This study can be used for strengthening mooring facilities and setting operational standards for safe port operation when large ships are berthing.
