The reality of dating violence was investigated among Japanese female and male college students. As a result,64.3-82.4 % of students reported expressing or receiving violence more than once, although only about 10% reported expressing or receiving severe violence. As to gender differences,men received more violence from their partners than women did. Althoughthere is no significant gender differences on the total frequencies of expressedviolence,men expressed more sexual abuse to their partner than women did. Multiple regression analyses revealed that parent\u27s attitude toward child had an effect on self-love for both genders. On the other hand, parental upbringing behavior had no direct influence on dating violence. For women,b ut not men,self-love had an egative effect on narcissism,and narcissism had animpact on expressed and received violence. It was suggested that narcissismcorrelates to aggression for women,because narcissism had more influence on expressed violence than received one. In conclusion,it was suggested that the psychological factors including narcissism,self-love and perception of parental upbringing behavior have an effect on dating violence for women. Therefore,education to empower youngpeople for nurturing self-love is essential to prevent dating violence. In addition,new methodology measuring psychological factors and effects of dating violence is required

Establishment of sandwich ELISA for soluble alpha-Klotho measurement: Age-dependent change of soluble alpha-Klotho levels in healthy subjects

Background α-Klotho (αKl) regulates mineral metabolism such as calcium ion (Ca2+) and inorganic phosphate (Pi) in circulation. Defects in mice result in clinical features resembling disorders found in human aging. Although the importance of transmembrane-type αKl has been demonstrated, less is known regarding the physiological importance of soluble-type αKl (sαKl) in circulation. Objectives The aims of this study were: (1) to establish a sandwich ELISA system enabling detection of circulating serum sαKl, and (2) to determine reference values for sαKl serum levels and relationship to indices of renal function, mineral metabolism, age and sex in healthy subjects. Results We successively developed an ELISA to measure serum sαKl in healthy volunteers (n = 142, males 66) of ages (61.1 ± 18.5 year). The levels (mean ± SD) in these healthy control adults were as follows: total calcium (Ca; 9.46 ± 0.41 mg/dL), Pi (3.63 ± 0.51 mg/dL), blood urea nitrogen (BUN; 15.7 ± 4.3 mg/dL), creatinine (Cre; 0.69 ± 0.14 mg/dL), 1,25 dihydroxyvitamin D (1,25(OH)2D; 54.8 ± 17.7 pg/mL), intact parathyroid hormone (iPTH; 49.2 ± 20.6 pg/mL), calcitonin (26.0 ± 12.3 pg/mL) and intact fibroblast growth factor (FGF23; 43.8 ± 17.6 pg/mL). Serum levels of sαKl ranged from 239 to 1266 pg/mL (mean ± SD; 562 ± 146 pg/mL) in normal adults. Although sαKl levels were not modified by gender or indices of mineral metabolism, sαKl levels were inversely related to Cre and age. However, sαKl levels in normal children (n = 39, males 23, mean ± SD; 7.1 ± 4.8 years) were significantly higher (mean ± SD; 952 ± 282 pg/mL) than those in adults (mean ± SD; 562 ± 146, P < 0.001). A multivariate linear regression analysis including children and adults in this study demonstrated that sαKl correlated negatively with age and Ca, and positively with Pi. Finally, we measured a serum sαKl from a patient with severe tumoral calcinosis derived from a homozygous missense mutation of α-klotho gene. In this patient, sαKl level was notably lower than those of age-matched controls. Conclusion We established a detection system to measure human serum sαKl for the first time. Age, Ca and Pi seem to influence serum sαKl levels in a normal population. This detection system should be an excellent tool for investigating sαKl functions in mineral metabolism

人は青年期において恋愛や性への関心を高め，他者と親密な恋愛関係を結ぶようになる。恋愛関係は深い相互作用を伴う対人関係であるため，その中で生じる肯定的体験も否定的体験も比較的情動的影響が深いものとなる。デートDVは恋愛関係で生じる否定的体験の中でも最も深刻な体験の１つである。また性交渉は青年の恋愛関係において一般的であり，カップルの関係性の質によって肯定的体験にも否定的体験にもなり得る。そこで本研究では，デートDV被害及び加害経験と性交渉による肯定的な情動体験との関連について検討をすることを目的に，性交渉による肯定的情動体験尺度の開発を行い，デートDV被害及び加害経験と性交渉による肯定的情動体験尺度得点との関連を検討した。その結果，ほとんど全てのデートDV経験にジェンダー差が見られ，デートDV被害及び加害経験と性交渉による肯定的な情動体験との間に関連があることが見出された。Young people are usually interested in romantic relationships and sexuality and usually form romantic relationships. Because romantic relationships involve deep interaction, both positive and negative experiences in romantic relationships tend to lead to deep emotional effects among young people. Dating violence is one of the most negative experiences in a romantic relationship. Intercourse may become either a positive or a negative experience. We examined the relationship between dating violence victims, assaults, and the positive emotional experiences of intercourse. We developed three hypotheses: (1) Couples who have intercourse experience more instances of dating violence and assaults than couples who do not have intercourse; (2) The larger the extent of dating violence among young victims, the fewer their positive experiences of intercourse in their romantic relationship; and (3) The larger the extent of assaults in dating violence among young victims, the fewer their positive experiences of intercourse in their romantic relationship. The hypothesis of this study were partially supported, but gender differences existed in almost all victims and all instances of assaults of dating violence

成人におけるデートDVの実態とダメージの認知 : 依存的恋愛観と暴力容認傾向との関連

500名の成人の未婚者を対象にインターネット調査を実施し、ダメージの認知を含むデートDV被害・加害経験の実態を検討した。またデートDVの背景には、恋人に依存したり、支配・束縛することを当然と考える「依存的恋愛観」があると考えられるので、依存的恋愛観の項目を作成し、依存的恋愛観や暴力容認傾向と被害・加害経験およびダメージの認知との関連についても検討した。その結果、男女差については、暴力容認傾向は男性の方が有意に高かった。被害・加害経験との関連では、男女ともに、被害・加害経験がある人は、依存的恋愛観や暴力容認傾向がより高い傾向が示された。また依存的恋愛観が高い人は精神的暴力を受けた際、暴力のダメージを低く認知していた。本研究では、被害・加害経験があったとしてもそのダメージを低く認知している人の存在が示唆されたため、今後は潜在的な被害・加害経験を掘り起こすような研究が必要である。またデートDVの要因となっている依存的恋愛観を考慮した予防教育が重要である。An online survey of 500 unmarried adults was conducted to examine the reality of dating violence. In particular,we focused on the association between possessive relationships, violence acceptance, and the understanding of damage resulting from violence. Although a possessive relationship is said to influence dating violence the youth tend to believe in such possessiveness in relationships and depend on and control their partners. The results revealed that men are involved in possessive relationships and violence acceptance more than women. With regard to violence, both women and men who expressed and received aggression were involved in possessive relationships and violence acceptance more than those who did not express or receive aggression. In addition, both men and women involved in possessive relationships tend to estimate lesser damage resulting from assaults when they receive psychological violence. In conclusion, we need to investigate potential violence and develop dating violence prevention programs that take into consideration possessive relationships in the future
