The aim of the present study was to assess the influence of hyperbaric oxygenation (HBO) on rat liver regeneration before and after partial hepatectomy. Rats were sacrificed 54 h after 15% hepatectomy, liver and body weights were measured, and serum alanine transaminase (ALT) and aspartate transaminase (AST) activity and albumin levels were determined. The lipid peroxide level, as indicated by malondialdehyde production in the remnant liver was measured, and liver sections were analyzed by light microscopy. Five groups of 10 rats in each group were studied. The preHBO and pre-hyperbaric pressure (preHB) groups were treated before partial hepatectomy with 100% O 2 and 21% O 2 , respectively, at 202,650 pascals, daily for 3 days (45 min/ day). The control group was not treated before partial hepatectomy and recovered under normal ambient conditions after the procedure. Groups postHBO and postHB were treated after partial hepatectomy with HBO and HB, respectively, three times (45 min/day). The preHBO group presented a significant increase in the initiation of the regeneration process of the liver 54 h postoperatively. The liver/body weight ratio was 0.0618 ± 0.0084 in the preHBO compared to 0.0517 ± 0016 g/g in the control animals (P = 0.016). In addition, the preHBO group showed significant better liver function (evaluated by the lowest serum ALT and AST activities, P = 0.002 and P = 0.008, respectively) and showed a significant decrease in serum albumin levels compared to control (P < 0.001). Liver lipid peroxide concentration was lowest in the preHBO group (P < 0.001 vs control and postHBO group) and light microscopy revealed that the composition of liver lobules in the preHBO group was the closest to normal histological features. These results suggest that HBO pretreatment was beneficial for rat liver regeneration after partial hepatectomy.

This research aims to identify and analyze the frequency of the researched determinants and outcomes of absenteeism and thus create an extensive pool of knowledge that can be used for further research. A systematic review, based on Tranfield, Denyer, and Smart’s guidelines of 2003, was used. An electronic search of the Scopus database led to the inclusion of 388 peer-reviewed research articles. Finally, 100 top-quality articles were analyzed using content analysis. This article provides several starting points for practitioners and researchers when investigating absenteeism and its potential determinants and outcomes. It also shows that there is an evident imbalance between empirical research dealing with determinants and research dealing with absenteeism outcomes. Employee attitudes stand out among the most repetitive absenteeism causes, while turnover, organizational health, and loss of productivity are some of the most researched absenteeism outcomes. Most research takes place in the manufacturing industries, followed by hospitals and other public service organizations, banks, and insurance companies. This systematic literature review is the first known attempt of this kind of review of the causes and consequences of absence behavior. It covers a wide range of literature published from 1969 until today and includes more than 150 different absenteeism determinants and outcomes.

Time management is the ability of consciously deciding and controlling the amount of time spent on different activities in order to be more productive and effective. In order to achieve academic success, students should be able to manage a large number of activities, from going to lectures, studying, participating in extra-curricular activities, to making sure they are getting enough rest to stay healthy. The purpose of this research was to determine if there are any significant differences in the effective time management between Chinese and Croatian students. Even though the cultural differences between these two groups are substantial, both groups are becoming a part of the same education and business market. The research was conducted on the sample of 340 Chinese and Croatian students using an online survey. The results have shown that in several time management activities there are statistically significant differences between Chinese and Croatian students. The results also indicate that the Croatian respondents are better at setting goals, determining priorities and performing tasks by priority, while Chinese students delegate tasks and determine and eliminate time wasting activities more often than their Croatian counterparts do. On the other hand, Croatian students waste more time on activities such as conducting tasks of small importance and fun activities of no relevance (e.g. "surfing" the Internet, private telephone conversations, chatting, etc.), while Chinese students are in the forefront with regard to ineffective and supernumerary meetings and overly long and supernumerary phone conversations.
