Some people still cannot talk freely about sex education. On the other hand, some of them have an assumption about teaching sex education will leads to free sex behavior. Sometimes parent afraid to talk about sex education with their children, even some parent think sex education is not important thing for children.However, in fact children need to know about sex education for their own good. To children, sex education is to explain differences in male and female and to know well about themselves. Create media to deliver sex education is the way to teach children about sex education. Among many media, game is one option to deliver this education.This research will discuss about game for childs sex media education. Use game as sex media education because game has capability to deliver message. Through game concept, picture, and animation, game deliver childs sex education to children. With the objective to prevent child from sexual abuse. However, when children play the game they need companion to make clear that children understand the meaning of game message through game story.

The paucity of clinical and preclinical studies investigating sex differences in sleep has resulted in mixed findings as to the exact nature of these differences. Although gonadal steroids are known to modulate sleep in females, less is known about males. Moreover, little evidence exists concerning the origin of these sex differences in sleep behavior. Thus, the goal of this study was to directly compare the sensitivity of sleep behavior in male and female Sprague Dawley rats to changes in the gonadal steroid milieu and to test whether the sex differences in sleep are the result of brain sexual differentiation or differences in circulating gonadal steroids. Here we report the magnitude of change in sleep behavior induced by either estradiol (E2) or testosterone (T) was greater in females compared with males, suggesting that sleep behavior in females is more sensitive to the suppressive effects of gonadal steroids. Furthermore, we demonstrated that the organizational effects of early gonadal steroid exposure result in male-like responsivity to gonadal steroids and directly alter the activity of the ventrolateral preoptic area (VLPO), an established sleep-promoting nucleus, in adult masculinized females. Moreover, the nonaromatizable androgen dihydrotestosterone did not suppress sleep in either males or females, suggesting that the T-mediated effect in females was due to the aromatization of T into E2. Together our data suggest that, like sex behavior, sex differences in sleep follow the classical organizational/activational effects of gonadal steroids.

Purpose The purpose of this paper is to describe the prevalence and factors associated with safe sex behavior among vocational students in Nakhon Ratchasima Province, Thailand, and to determine the modifying factors listed as socio-demographic characteristic, the level of HIV and sexually transmitted infections’ knowledge, attitude toward reproductive health, and safe sex behavior among vocational students in Nakhon Ratchasima Province, Thailand. Design/methodology/approach A cross-sectional descriptive research was conducted from August to October 2018. The multistage stratified sampling, combined with purpose and random sampling, was used to select the participants. One vocational college with the highest number from urban, suburban and rural areas was purposely selected. The sample calculation by using Cochran’s formula, a random sampling by drawing from each college with male and female, was made to obtain the sample size of 355 students. Inclusion criteria included: vocational students, both male and female, aged between 15 and 19 years, resided in the study area, and volunteered to participate. Ethical consent including waiver of the parent’s consent for the participant aged under 18 years for this study was approved by the Institution Review Board for Human Research Ethics, Chulalongkorn University (Certification number JV 823/2561) A self-administered questionnaire was adapted by the principle researcher from the illustrative questionnaire for interview survey with young people (14), and The study of Prevalence of HIV, STD, Drug Use and Risk Behaviors in Adolescents and Young Adults, in Chaing Rai, Thailand (PRAYA) tool (15). All statistical analyses were performed by SPSS version 22. Findings The finding revealed that 332 participants were male (57.8 percent) and female (42.2 percent) with an average age of 16.8 years (±1.7). Approximately 60 percent of males and 50 percent of females had experience of sexual intercourse, with their first experience of sexual intercourse at the average age of 15. Most respondents 63.1 percent used a condom and 63.6 percent used contraception in their latest sexual intercourse. About 41.9 percent consumed alcohol and 15 percent reported substance abused. Sexual intercourse among adolescents vocational students were significantly associated with high knowledge of contraception (OR=0.30, 95%CI=0.10–0.82). Positive attitude toward reproductive health had a significant association with sexual intercourse (OR=0.17, 95%CI=0.05–0.58). Sexual intercourse among vocational students were also significant associated with low risk behavior (OR=0.45, 95%CI=0.22–0.91) and high risk behaviors (OR=0.24, 95% CI=0.10–0.59). Contraceptive used in the latest sexual intercourse had a significant association with cues to action (OR=0.43, 95% CI=0.22–0.86). Research limitations/implications This study used a self-reported questionnaire to collect information from participants about safe sex behaviors, which might contain bias data and socially desirable answers. The time for collecting data did not match vocational students’ schedule as they were about to have their final exams. An error in this questionnaire was the absence of condom use as one of the contraception methods. Practical implications The study showed that both male and female vocational students in Nakhon Ratchasima have a low level of knowledge of HIV, STIs and contraception. This study revealed that females have higher knowledge of all the factors more than males. Males usually received more harassment from peers for being sexually active than females do. Condoms and contraceptive used are inconsistent in all research conducted and have no common ground. Communication related to sex for those who have no partner was poor compared to students who have a partner. The four factors associated with safe sex behaviors should always be considered and surveyed among vocational students, as the study showed that all results vary for a future adolescence study. Social implications This research aims at government authorities. The policy makers should include reproductive health and rights in the curriculum. The Ministry of Public health and The Ministry of Education should provide training for the trainer program for teachers concerning safe sex behaviors. For future research, in-depth interview and qualitative study should be used to increase the reliability of the result of the inconsistency of using a condom and contraception. The researcher should do further studies into vocational college semester schedules before collecting data and should spend more time in the college, so the students become more acquainted to the researcher and give a more truthful answer. Moreover, condom use should be added as one of the contraception methods. Originality/value This is the first study among vocational students in Nakhon Ratchasima Province which emphasizes specifically on safe sex behaviors and factors related to it. Regarding the population of vocational students, this study covers almost 80 percent of the population. Sensitive questions for sexual activity status and sexually history were answered by a self-administered questionnaire in order to increase sincere answers on their experiences because participants were not shy to disclose their sexual experiences.

Phosgene still plays an important role as a toxic substance in the chemical industry. Thiess (1968) recently reported observations on numerous cases of phosgene poisoning. A serious difficulty in the clinical handling of phosgene poisoning cases is a relatively long latent period, up to 12 hours, with no obvious signs of severity. At about 12 hours heavy lung edema appears suddenly, however changes can be seen in routine X-rays taken after only a few hours' exposure (Diller et al., 1969). This study was undertaken to correlate these early changes seen by the roengenologist with morphological alterations in the lungs seen in the'light and electron microscopes.Forty-two adult male and female Beagle dogs were selected for these exposure experiments. Treated animals were exposed to 94.5-107-5 ppm phosgene for 10 min. in a 15 m3 chamber. Roentgenograms were made of the thorax of each animal before and after exposure, up to 24 hrs.

Gonadotroph cell adenomas of the pituitary are infrequent in human patients and are not invariably associated with altered gonadal function. To date, no animal model of this tumor type exists. Herein, we describe spontaneous gonadotroph cell adenomas in old male and female Sprague-Dawley rats by histology, immunocytology and electron microscopy.The material consisted of the pituitaries of 27 male and 38 female Sprague Dawley rats, all 26 months of age or older, removed at routine autopsy. Sections of formal in-fixed, paraffin-embedded tissue were stained with hematoxylin-phloxine-saffron (HPS), the PAS method and the Gordon-Sweet technique for the demonstration of reticulin fibers. For immunostaining, sections were exposed to anti-rat β-LH, anti-ratβ-TSH, anti-rat PRL, anti-rat GH and anti-rat ACTH 1-39. For electron microscopy, tissue was fixed in 2.5% glutaraldehyde, postfixed in 1% OsO4 and embedded in epoxy-resin. Tissue fixed in 10% formalin, embedded in epoxy resin without osmification, was used for immunoelectron microscopy.

In this abstract we Illustrate how same-section correlative light and high voltage electron microscopy (HVEM) of serial 0.25-0.50-μm sections can answer questions which are difficult to approach by EM of 60-100 nm sections.Starfish (Pisaster and Asterlas) eggs are fertilized at meiosis I when the oocyte contains two maternal centrosomes (e.g., asters) which form the poles of the first meiotic spindle. Immediately after fertilization a sperm aster is assembled in the vicinity of the male pronucleus and persists throughout meiosis. At syngamy the sperm aster splits to form the poles of the first mitotic spindle. During this time the functional and replicative properties of the maternal centrosome, inherited from the last meiotic division, are lost. The basis for this differential stability, of male and female centrosomes in the same cytoplasm, is a mystery.

Speech Naturalness

Purpose The purpose of this study was to investigate how speech naturalness relates to masculinity–femininity and gender identification (accuracy and reaction time) for cisgender male and female speakers as well as transmasculine and transfeminine speakers. Method Stimuli included spontaneous speech samples from 20 speakers who are transgender (10 transmasculine and 10 transfeminine) and 20 speakers who are cisgender (10 male and 10 female). Fifty-two listeners completed three tasks: a two-alternative forced-choice gender identification task, a speech naturalness rating task, and a masculinity/femininity rating task. Results Transfeminine and transmasculine speakers were rated as significantly less natural sounding than cisgender speakers. Speakers rated as less natural took longer to identify and were identified less accurately in the gender identification task; furthermore, they were rated as less prototypically masculine/feminine. Conclusions Perceptual speech naturalness for both transfeminine and transmasculine speakers is strongly associated with gender cues in spontaneous speech. Training to align a speaker's voice with their gender identity may concurrently improve perceptual speech naturalness. Supplemental Material https://doi.org/10.23641/asha.12543158
