The development of vegetable subsector in Habru district faces various marketing problems to supply their produce to the market. Therefore, this study was aimed to identify the determinants of vegetables market supply in Habru district. Data for the study were collected from primary and secondary sources. Primary data were collected from a randomly selected 147 vegetable producer households. Descriptive statistics and multiple regression econometric methods were used for identifying determinants of vegetable market supply. The test for assumptions of the classical linear regression model showed endogeneity in market supply analysis and hetero skedasticity problem in tomato supply analysis. Two-stage least squares result showed that quantity produced, farming experience and extension contact significantly and positively affected the quantity of onion supplied to the market whereas the age of the household head significantly and negatively affected it. Robust multiple linear regression results showed that quantity produced, education level, family size and extension contact positively and significantly affected the quantity of tomato supplied to the market whereas distance to the market affected it negatively and significantly. The study recommends the need to boost production and provision of market-oriented extension, support technological advancement in production and marketing, enhance farmers experience and education status.

Objective: To explore the role of lingual frenectomy in the treatment of ranulas. 

Methods: In this study, we retrospectively reviewed 45 patients with ranulas accompanied by short lingual frenulum, they were randomly assigned to the frenulum correction group(n=24) and the control group (n=21). The following data were obtained, including age, sex, site of ranula, preoperative period of observation, diameter of ranula, duration of follow-up and the results.

Results: Our results demonstrated that the mean age of the patients was 13.6 ± 2.56 years. Among 24 cases treated by frenulum correction, 15 ranulas had a full regression of the lesion after one month. 9 ranulas had no change after frenulum correction. By comparison, in the control group, only 5 cases were disappearance. There was significant difference between two groups (p < 0.05).

Conclusion: The findings indicated that increased tongue movement after lingual frenulum surgery is beneficial to the disappearance of ranulas, and lingual frenectomy is an adjuvant approach in the treatment of ranulas adjacent to lingual frenulum.

The present study examined the effect of the head mounted display (HMD) virtual reality games in the functionality of children with cerebral palsy (CP). The intervention program lasted 8 weeks, with a frequency once a week. The participants were 8 children with CP, aging 10 to 11 years old, following the rehabilitation program of a daily center within the wider area of Athens. The participants, randomly assigned to the experimental and control conditions (EG & CG), were ambulatory and classified according to the GMFCS E & R in classes I (N=4), II (N=2) and III (N=2). The EG followed the weekly rehabilitation schedule plus an hour per week exposure to two different HMD virtual reality games chosen by the students. The CG followed the weekly rehabilitation schedule, and both groups declared absence of any organized activities beyond the rehabilitation center during the 8 week intervention. The participants were assessed at the begin and at the end of the intervention program in the functionality measures, according to the ICF.

The statistical analyses revealed significant improvement in the 30sSTS (F=19.271, p=.007, η2=.794) and elbow range of motion (F=7.089, p=.045, η2=.586) and approached significance in walking ability (1 Minute Walking Test) and gross motor function (GMFM D & E). Further, the participants recorded no episodes of dizziness, experienced enjoyment throughout the intervention, while no adverse effects with respect to spasticity were found. 

Conclusively, the HMD virtual reality games may improve the functionality of children with CP and they provide a positive experience without any adverse effects. The HMD games therefore may be considered in the future to add in the rehabilitation programs of children with CP.
