This study compares the antioxidant and anti-inflammatory capacities of acetone extracts obtained from commercially available tomatoes (gangwon chal, wansuk, cherry, daechu cherry, plum, and campari). Campari and cherry tomatoes had the highest levels of 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical, 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical, and hydroxyl radical scavenging activities, as well as cupric reducing antioxidant capacity (CUPRAC), followed sequentially by gangwon chal, daechu cherry, plum and wansuk varieties. Highest peroxynitrite scavenging activity, oxygen radical absorbance capacity (ORAC), and total phenolic contents were obtained in campari tomatoes, followed by cherry, gangwon chal, daechu cherry, plum and wansuk varieties. Lycopene contents were highest in cherry tomato, followed by daechu cherry and campari, and were lowest in the gangwon chal, plum and wansuk varieties. Maximum inhibition of the lipopolysaccharide-induced nitric oxide production in RAW 264.7 cells was observed in campari tomatoes, followed by cherry, daechu cherry, gangwon chal, plum and wansuk varieties. Antioxidant activities, including hydroxyl radical and peroxynitrite scavenging, ORAC, and CUPRAC, showed a high correlation with the total phenolic or lycopene contents. Anti-inflammatory capacity was highly correlated with antioxidant activities, total phenolic, and lycopene contents. Taken together, findings of the current study demonstrate that campari and cherry tomatoes have the most potent antioxidant and anti-inflammatory effects, which are closely related to the lycopene as well as polyphenolic contents.

This study was designed to verify two things. The first is to verify the relationship between citizens' perception of police legitimacy and acceptance of police use of force. The second is to verify the mediating effect of the sense of obligation to comply with the law in the relationship between police legitimacy and police use of force. To achieve the research objectives, an online survey was conducted on 539 Seoul citizens. After that, the analysis was performed using the SPSS 27.0 program and the Model 4 analysis method of the Macro Process Model 4.2. As a result, it was confirmed that the increase in citizens' perception of police legitimacy leads to an increase in citizens' perception of the legitimacy of exercising police physical power. Specifically, multidimensional police legitimacy, procedural fairness, police effectiveness, distributive fairness, and legality all had a significant and positive effect on the recognition of the legitimacy of the exercise of police physical power. However, the mediating effect of the sense of legal compliance obligation could be confirmed only in one of the sub-factors of multidimensional police legitimacy. Based on the research results, a plan to raise the awareness of police legitimacy and police physical power was suggested.

The objective of the present study was to investigate the inhibitory effect of physiologically pulsatile pattern of testosterone(T) on luteinizing hormone(LH) in wethers. To do this, 3 separate experiments were conducted. Infusion rates and patterns needed to produce normal T secretory profiles found in intact rams were established in Experiment 1, the time-course of the suppressive effect of T on circulating LH concentrations was determined in Experiment 2, and the effectiveness of a pulsatile versus a constant pattern of T to suppress LH secretion in wethers was compared in Experiment 3. In Experiment 1, three different doses(25, 50 or $100{\mu}g$) of T were injected intravenously to animals to do pharmacokinetic analysis of T. Elimination rate constant, volume of distribution, and total body clearance of T averaged $0.18min^{-1}$, 0.531/kg BW, and 0.091/min/ kg BW, respectively. In Experiment 2, three different doses(192,384, or $768{\mu}g/kg/24h$) of T were infused at 4h intervals for 3 days into animals to evaluate the time course of the inhibitory effect of T on mean LH concentration. As duration of T infusion increased, mean LH concentrations gradually reduced. Mean LH concentrations were significantly lower at day 2 or day 3 than at day 0. However, mean LH concentrations did not differ between day 0 and day 1 or between day 2 and day 3. In Experiment 3, animals were subjected to two different intravenous infusion regimens for 3 days: constant T($768{\mu}g/kg/24h$) and pulsatile(one pulse every 4h) T($768{\mu}g/kg24h$). Blood samples were collected at 10-min intervals for 4h both prior to infusion and during the last 4h of the infusion. Mean LH was more suppressed(p=0.045) by constant T than by pulsatile T. LH pulse amplitude was not affected by constant T or pulsatile T. LH interpulse interval was increased more(p=0.034) by constant T than pulsatile T.
