  • Biogenic monoamines are divided into three categories; catecholamines(dopamine, norepinephrine, and epinephrine), indoleamine(serotonin and melatonin) and histamine. Among them, serotonin has been intensively studied by many researchers with a broad spectrum of biomedical interests. A concise overview of serotonin-related topics such as biosynthetic pathway, receptor subtypes, and roles in reproduction will be provided. In particular, serotonergic efffect on the regulation of hypothalamus-pituitary-gonad hormonal axis and sexual behaviors will be emphasized. Though our Knowledge on the biological roles and its clinical applications are still limited, these topics are quite promising subjects which will be helpful for improving our 'quality of life' in near future.

  • Authors reviewed 73 cases of primary skin cancer arising from head and neck, including comparative clinical data of 63 cases of squamous cell carcinoma and basal cell carcinoma retrospectively. There was no significant sexual predilection in each type of cancer and 77% of all cases were occurred after age of 50. The data of occurring site and occupation(farmer; 41%) implied that sunlight exposure strongly concerned in development of skin cancer. Comparing the data of 63 cases of squamous cell carcinoma and basal cell carcinoma, authors found out no remarkable difference in mean diameter of primary lesion at first visit of clinic, but some difference in mean duration, the percentage of the cases less than 1 year­duration and percentage of T1 lesion with no statistical significance(p>0.05). Combination of surgery and radiotherapy had relatively lower recurrence rate (11%) than surgery alone (13%). Squamous cell carcinoma had higher recurrence rate(34%) and metastasis rate(28%) than basal cell carcinoma; 6% and 3%, respectively(p<0.05).

  • Purpose: The purpose of this study was to develop a scale to assess immigrant women's needs for pregnancy and postpartum adaptation and to test the reliability and validity of the scale. Methods: To construct scale items, critical issues and difficulties associated with pregnancy and postpartum adaptation of immigrant women were identified and categorized through a literature review. Fifty-two scale items were constructed, and data for validity and reliability testing was collected with a questionnaire survey from 367 immigrant women. Data were analyzed with descriptive statistics, factor analysis, and reliability coefficients. Results: The final measurement scale to assess immigrant women's pregnancy and postpartum adaptation consisted of 48 items and 7 factors (adaptation to daily activity during pregnancy, cross-cultural understanding and personal respect, understanding of the process of pregnancy and delivery, baby rearing and family support, physical and emotional adaptation after childbirth, nutrition during pregnancy, and sexual life adaptation). The seven factors accounted for 64.26% of the variance, and Cronbach's ${\alpha}$ was .96. Conclusion: The scale developed by this study is a reliable and valid instrument and can be used to assess needs of pregnancy and postpartum adaptation and can be utilized in providing nursing interventions for immigrant women.

  • Purpose: The purpose of this study was to investigate the relationships between psychosocial working conditions and psychological well-being depending on the gender among Korean interactive service workers. Methods: This study was a secondary analysis of the data extracted from the 2011 Korean Working Conditions Survey. For the present analysis, 15,669 workers who interact with others at work were selected. Based on the existing literature, a set of variables was chosen from the KWCS. Psychological well-being was measured using the WHO-5 well-being index. Results: The prevalence of poor psychological well-being was significantly higher among men (43.1%) than women (39.6%). Women were more likely to be exposed to demands for hiding emotions, bullying, and discrimination, whereas men were more likely to be exposed to psychological job demands, cognitive demands, demands for responsibility, role conflict and long working hours. Most factors were associated with poor well-being among women and men except demands for hiding emotions, skill discretion and development, physical violence, and sexual harassment. Conclusion: Based on these results, some practical suggestions are offered to help interactive service workers adjust to their duties.

  • Objectives: This study was to develop a reliable and valid instrument measuring the reproductive health promoting behavior of undergraduates. Methods: The initial questionnaires were made of 106 items from four domains through literature review. All questionnaire items were revised by an expert group and a pilot test. Data were collected using the revised initial questionnaire of men's 58 items and female's 64 items from 634 male and 685 female undergraduate students. The collected questionnaires were analyzed by factor analysis using varimax rotation to evaluate the construct validity. Results: According to the gender, two measurement were invented and analysed separately. Four common factors consisting of 'safe sex', 'sexual responsibility', 'genital health management' and 'STD prevention' were discovered in both groups. The 'genital hygiene' factor was added as a female factor. Male students' scale was made up 4 factors 16 items and female students' scale was made up 5 factors 18 items. Cronbach's alpha for male scale was estimated to be .892 and female scale to be .882. Conclusions: This scale will make it possible to measure the level of reproductive health among Korean university students. This scale may be useful for developing effective methods of education as well as policy programs for improving the reproductive health of Korean university students.

  • The term Japonism was coined in France where the predilection for Japanese art forms was immediately apparent, influencing Impressionism, Symbolism, Post-Impressionism, and later the Art Nouveau movement, all of which reflect aspects of Japanese art adapted to Western style. The 1968 May Revolution in Paris changed traditional thinking and shifted the center of fashion of the 1970's from haute couture to pret-a porter. At about the same time, having recovered from the destruction of war, Japan started to emerge as a leading economic force. The Japanese clothing designers, who were inspired by their own traditions, began to present their collections in the West. Hanae Mori's dresses with Japanese floral motifs were the first to appear. The West was captivated by the colorfully layered clothing of Kenzo Takada inspired by peasant and working class kimonos. And Issey Miyake was acclaimed for his innovative concepts of ‘one piece of cloth'. In the 1980s Rei Kawakubo and Yohji Yamamoto achieved recognition with their deconstructivist and minimalist approaches to fashion. The clothing proposed by these Japanese designers has transcended not only national and sexual boundaries, but also those of accepted materials in which to work. These designs suggest new possibilities and are unrestricted by preconceived ideas of kimono or of Western clothing. The emergence of Japanese designers as a powerful creative force in the late twentieth century has created a new dimension to the term Japonism in fashion. By integrating the clothing traditions of the West and Japan, while at the same time departing from them, a new international genre of clothing has been created.

  • Referring to John Irving's 2001 published fiction The Fourth Hand, the publisher commented, "It seems, at first, to be a comedy, perhaps a satire, almost certainly a sexual farce. Yet, in the end, it is as realistic and emotionally moving as any of Mr. Irving's previous novels." In his early six novels, John Irving shows the world suffused with grief and deception. But his novels finally turn out also as a comic and robust novel. The writer's success in achieving this thick description of the contradictory modern world is largely due to his development of the idea of the flawed hero. Despite loss, sadness and abandonment, Irving's heroes maintain classical heroic traits such as intelligence, tenderness, protectiveness, strength, bravery, sense of humor, independence, attractiveness. In this article, I tried to emphasize these graces potent in Irving's heroes as the most attractive and influential device for the writer's consistent popularity among the general public. The cinematization of his four fictions attest to audience's sympathy toward rewarding vulnerability and truthful exaggeration in the depiction of Irving's heroes. By taking full responsibility for their own fate despite having the flaws, Irving's protagonists still appeal to many readers as heroes resilient in a modern chaotic world without losing their graces.

  • Since December 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread rapidly, resulting in a pandemic. The virus enters host cells through angiotensin-converting enzyme 2 (ACE2) and transmembrane protease serine subtype 2 (TMPRSS2). These enzymes are widely expressed in reproductive organs; hence, coronavirus disease 2019 (COVID-19) could also impact human reproduction. Current evidence suggests that sperm cells may provide an inadequate environment for the virus to penetrate and spread. Oocytes within antral follicles are surrounded by cumulus cells, which rarely express ACE2 and TMPRSS2. Thus, the possibility of transmission of the virus through sexual intercourse and assisted reproductive techniques seems unlikely. Early human embryos express coronavirus entry receptors and proteases, implying that human embryos are potentially vulnerable to SARS-CoV-2 in the early stages of development. Data on the expression of ACE2 and TMPRSS2 in the human endometrium are sparse. Moreover, it remains unclear whether SARS-CoV-2 directly affects the embryo and its implantation. A study of the effect of SARS-CoV-2 on pregnancy showed an increase in preterm delivery. Thus, vertical transmission of the virus from mother to fetus in the third trimester is possible, and further data on human reproduction are required to establish this possibility. Based on analyses of existing data, major organizations in this field have published guidelines on the treatment of infertility. Regarding these guidelines, despite the COVID-19 pandemic, reproductive treatment is crucial for the well-being of society and must be continued under suitable regulations and good standard laboratory practice protocols.

  • Phaeosphaeria species are pathogenic on wheat, barley and a wide range of wild grasses. To analyze mating type loci of the Phaeosphaeria species and investigate mating type distribution in Iran, we sequenced mating type loci of 273 Phaeosphaeria isolates including 67 isolates obtained from symptomatic leaves and ears of wheat, barley, and wild grasses from two wheat growing region in Iran as well as 206 isolates from our collection from other regions in Iran which were isolated in our previous studies. Mating type genes phylogeny was successfully used to determine the species identity and relationships among isolates within the Phaeosphaeria spp. complex. In this study, we reported seven new host records for Phaeosphaeria species and the Phaeosphaeria avenaria f. sp. tritici 3 group was first reported from Iran in this study. Mating type distribution among Phaeosphaeria species was determined. Both mating types were present in all sampling regions from Iran. We observed skewed distribution of mating types in one region (Kohgiluyeh va Boyer-Ahmad) and equal distribution in the other region (Bushehr). However, when considering our entire dataset of 273 Iranian Phaeosphaeria isolates, the ratio of mating types was not deviated significantly from 1:1 suggesting possibilities for isolates of opposite mating type to interact and reproduce sexually, although the sexual cycle may infrequently occur in some regions especially when the climatic conditions are unfavorable for teleomorph development.
