This study is a descriptive survey which attempts to understand family strength, parenting attitude, and the ego-identity perceived by female high school students and identify the factors influencing ego-identity of the students. Methods: Data collection was carried out through a questionnaire survey of 186 female high school students. The collected data were analyzed by descriptive statistics, t-test. ANOVA, correlation analysis, and multi-variate regression analysis while using SPSS 23.0 program. Results: Family strength and the ego-identity perceived by female high school students were at a mid-level, with an average of 207.76 and 149.72 points, respectively. Parenting attitude showed scores higher than the mid-level, recording 90.36 points in average. As a result of analyzing the correlation between the factors, the higher family strength and the ego-identity of female high school students were, the better were the patenting attitudes of perceived parents. Besides, family health, parenting attitude, and family form (nuclear family) were found to be the factors influencing ego-identity formation of female high school students with the explanatory power being 25.5% in total. Conclusion: Developing intervention programs which take into account family strength is considered necessary to help the youth form positive ego-identity.

Food irradiation is an effective quarantine treatment for fresh agricultural commodities. This study aimed to use different analytical methods, such as the electronic tongue (e-tongue), photostimulated luminescence (PSL), and electron spin resonance (ESR), to determine the screening and/or detection properties of electron beam-irradiated mandarin oranges at 0, 0.4 and 1 kGy during 15 days of storage at 4°C. Principal component analysis (PCA) based on e-tongue profiles could potentially discriminate irradiated orange samples from nonirradiated ones for up to 10 days of storage. Calculating PSL ratios also aided in screening the irradiation status of the oranges until 15 days of storage. ESR spectroscopy with various pretreatments (freeze drying/FD, vacuum drying/VD, ethanol extraction & vacuum drying/EVD) increased the signal intensity of radiation-induced cellulose radicals in the samples. Such a process enabled their detection for up to 5 days of storage for 0.4 kGy-irradiated orange samples and 15 days for 1 kGy-irradiated samples, respectively, where the irradiated orange samples showed superior detection results in the order of EVD ⟩ VD ⟩ FD in the pretreatment method.
