The objectives of this study are to identify health behaviors and health problems. and the relations between health behaviors and health problems of female workers in the retail business. The number of subjects were 200 female workers of 6 department stores in Seoul and Kyonggi area, whose jobs last more than 6 months as retail employees. The data was collected during 2 months from July 1 to August 30, 1998. The Cornell Medical Index Health Questionnaire(CMI) was used to measure their health problems, while health behaViorn were investigated in terms of 'smoking', 'alcohol', exercise', 'diet', and 'sleeping'. The data were analyzed with frequency. percentage, t-test, ANOVA test, and $X^2-test$ by SPSS PC+ program. The results of this study are as follows: 1. Out of health problems. Digestive symptoms occupied the highest percent number. nervous ones the second and cardiovascular ones the third among physical health problems of retail female workers. The most frequent mental health problem was 'adequacy' and the next, 'tension' and 'anger', 2, Health problems according to general characteristics of subjects were shown that the younger or the unmarried complained more than the older or the married, especially in the items of 'eye and ear', 'respiratory system', 'cardiovascular system', 'digestive tract', 'nervous system', 'adequacy', and 'depression'. The longer working duration they have had, the more they complained of 'respiratory system' and 'adequacy'. The lower academic careers complained of 'nervous' than the higher ones with statistical significance. 3. The analysis of daily health clinic notes showed that respiratory complaints were the highest percent, successively followed by digestive tract, nervous one, external injury, musculoskeletal system, urinary-reproductive system and others. 4. The level of their health practice was generally low in smoking, diet habit and alcohol intake, exercise, sleeping, very low especially in smoking, diet, alcohol intake, and exercise among them all. 5. Present smokers and ones with past experience complained of physical and mental health problems of 'respiratory system', 'digestive tract', 'skin', 'nervous', 'urinary-reproductive system', 'fatigability', adequacy', 'depression', 'anxiety', 'anger' and 'tension', than non smokers, with statistical difference. Workers without having breakfast and with irregular diet had more complaints on 'digestive tract', 'adequacy' and 'tension', than those who had regular dietary habit. The less the subjects slept, the more they complained of eye and ear, cardiovascular system. The subjects who drank alcohol complained more digestive problem. However, whether they exercise or not did not affect physical and mental health problems in a significant manner. 6. The subjects' age and marital status were statistically significant relating to health behaviors, as the younger or unmarried recorded a low level of health practice in smoking, drinking, dietary habit. Based on the results, the suggestions are made as follows: 1. Health education program on smoking, alcohol intake, diet habit is needed to improve health problems and health behavior of female retail workers. 2. The unmarried workers of late teen and twenties, who are transitional period from teenagers to adulthood are important targets for health promotion program especially for maternal health. 3. Better working environment with sufficient time and facilities for workers to relax is required to promote female sales workers' health. 4. Further research is required to identify the relation between workers' visual fatigue and intense lights for the display of goods.

Oviposition and egg laying is an important physiological and behavioural event in the life cycle of the silkworm, Bombyx mori (L). Oviposition and egg laying is dependent on a number of intrinsic and extrinsic factors viz., neural, hormonal, environmental, physical, behavioral etc for the perpetuation of population. Although, the virgin female moths have fully developed embryos but active egg laying begins under the influence of mating which provides essential copulation stimulus for oviposition. After mating drastic biochemical changes occurred that incites egg laying under the influence of optimum environmental conditions. Weight of pupae as well as larval density has significant role on oviposition and egg laying behaviour in the silkworm wherein high pupal weight and inadequate rearing space affects not only the biology, morphology and physiology but also the oviposition and egg laying. Surface topography, plane of inclination, mating length, age of male moth, temperature and photoperiod etc has significant effect on reproductive physiology of silkworm. An attempt has been made in this review article to elucidate briefly the works carried out on mating behaviour, direct and indirect copulation stimulus, vitellogenesis, influence of environmental factors besides effect of weight of pupae and or pharate adult and larval density on oviposition and egg laying behavior in the silkworm, B. mori and its significance in silkworm seed production.

The purpose of this article was to get hold of adolescent's needs for sex knowledge and to reveal their understanding of sex. These results may be applied to the sex education and counselling for adolescent. The participants of study were 267 students (females, 144 ; males, 123) who were the first and second grade form 1 middle and 2 high schools. They were asked to describe 3 questions that they wanted to know or to learn about sex. Their questions about sex were total 779(girls, subtotal 456, mean 3.2, boys, subtotal 323, mean, 2.6). These questions categorized to 9 items by content analysis. The items were ‘sexual drive, behavior and tendency(229, 29.4%)’ , ‘anatomy and physiology of reproductive system(140, 18.0%)’, ‘reproduction(131, 16.8%)’, ‘concept of sex(31, 4.0%)’, ‘acquaintance between the other sexes(17, 2.2%)’, and ‘the others(9, 1.2%)’ in order of frequency. The most frequent item that the student want to know or team about sex was ‘sexual drive, behavior and tendency’ except girls of sophomore in middle school. There were several features in participants' needs for sex knowledge as respects of the understanding of sex- biological sex, gender, and sexuality. The prominent feature in knowledge need of bio logical sex was that the participants had the interests according to their biological sex. They had the negative attitude to the phenomenons (ex, menstruation and pregnancy, phimosiectomy, etc) that they experienced or would experience due to their biological sex. A part of them asked the questions based the misconceptions and used the slangs or ‘××’, ect. to name the male or female genitalia. The male students wanted to know the female genitalia. The participants' understanding of gender reflected the sexism of our society, but they didn't accept and had doubts about the dual, hierarchical structure of that. The students, especially female seemed to be powerless to the harms of the sexual violence. Girls had much interest in their appearances and complained to our sexual culture that women comforted and served men. The participants had the dual perspective that the sexuality as respects of physiologic phenomenon was considered as natural but that as related to heterosexuals was as negative. And they deemed that men's sexual drive was stronger than women's and was difficult or was not able to be inhibited. They had much interests in homosexuality but reflected the negative attitude to that in our society. Adolescent felt wonder why the expressions of sexuality of adult were permitted but theirs were not. Lastly, a part of boys substituted querying the sexuality of animals for asking that of human. Maybe it was because of the embarrassment to talk about human's sexuality directly. The teenaged participants understood that the sex had not only the biological meanings but also the sociocultural meanings. They regarded the sex as natural and wanted to know it, but they had conceptions that it was difficult and embarrass to talk about it openly and directly.

This study investigated the potential effects of amitraz on the pre- and postnatal development, behavior, and reproductive performance of offspring of parent rats given amitraz during pre-mating, gestation, and lactation. The test chemical was administered via the drinking water containing 0, 40, 120, and 360 ppm to male rats from 2 weeks before mating to the end of 14-day mating period and to females from 2 weeks before mating, throughout mating, gestation and lactation up to weaning. Based on fluid consumption, the male rats received an average of $0,\;5.7{\pm}1.33,\;13.2{\pm}2.08,$ and $35.8{\pm}3.42$ mg/kg/day amitraz, and the female rats received an average of $0,8.7{\pm}4.42,\;20.1{\pm}9.60,\;and\;47.6{\pm}22.38$ mg/kg/day amitraz, respectively. At 360 ppm, an increase in the incidence of abnormal clinical signs, a suppression in the body weight gain, a decrease in the food consumption and litter size, an increase in the post-implantation loss, and a decrease in the seminal vesicle weight were observed in the parent animals. In addition, a suppression in the body weight gain, a decrease in the grip strength, a delay in the negative geotaxis, an increase in the pre- and post-implantation loss, and a decrease in the number of live embryos were observed in the offspring. At 120 ppm, suppressed body weight gain and reduced food consumption were observed in the parent rats. Suppressed body weight gain and decreased grip strength were also observed in the offspring. There were no signs of either reproductive or developmental toxicity at 40 ppm. Under these experimental conditions, the no-observed-adverse-effect level of amitraz for parent rats and their offspring was estimated to be 40 ppm in rats.

Background: Breast cancer is the most frequently diagnosed malignancy and the leading cause of cancer death among women worldwide. In Morocco, there have been few recent descriptive studies on female breast cancer. The aim of this study was to describe the latest available incidence and mortality rates of breast cancer among Moroccan women and to compare them with rates in other regional and Western countries. Methods: For this descriptive study, Moroccan incidence data were obtained from the most recent reports of the cancer registries of Casablanca and Rabat. Information on breast cancer incidence for different countries were obtained primarily from publicly available cancer registries and Cancer Incidence in Five Continents, Volume X. Mortality data were extracted from the GLOBOCAN 2012 published by the International Agency for Research on Cancer. Results: The age-standardized incidence (World) rate of breast cancer in Moroccan women increased from 35.0 to 39.0 per 100,000 women between 2004 and 2008, showing an annual increase of 2.85 %. The highest incidence rates were registered in the age groups of 45-49, 50-54 and 55-59 years (106.1, 108.2 and 108.5 respectively). Sixty-nine percent of female breast cancer cases were diagnosed at stages II and III. In 2012, the estimated number of women who died of breast cancer in Morocco was 2,878. The crude, age-standardized (World) mortality rates were 17.3 and 18.0 per 100,000, respectively. Conclusion: Although the incidence of female breast cancer in Morocco is lower than in Western countries, evidence shows that the rate is rising. This increase of breast cancer incidence has been observed in parallel with changes in reproductive behavior and adoption of a Western lifestyle. Prevention policies need to be implemented.

The goal of this research was to provide the basic data of sexual education for late schooler by finding out what they want to know about sex, or to see, if any, its relevancy between female and male students and between each grade. The sample for this research was a total of 453 students in 4th, 5th and 6th grade from 12 different classes at two elementary schools which were located in C city and in B province. The children were requested to write down three points on what they want to know or to learn most about sex, and their answers were put through two analytical stages in order to classify and to examine. The followings are the conclusions from the data. 1. The female cluster took 44.2% out of the whole sample, and there were 151 students per each grade. The specific girl ratios for each grade were 42.4%, 50.3% and 39.7% respectively. 2. It was noted that a total of 1,195 questions were gathered from the students writings, 45% of the questions was raised by the female students. The 4th grade students raised 432questions (43.8% by the girl) while the 5th. and the 6th grade students raised 387 (53.2% by the girl) and 376 questions (42.3% by the girl) respectively. The average number of questions per students was 2.6 while the female students raised 2.8 questions which was more than the average 2.5 questions by male students. It was the 4th grade female student cluster, which raised the most question (3.0) while the 6th grade male students raised the least question (2.4) in average. 3. The questions raised by the children could be divided into seven categories of the knowledge need on sex. They were Reproduction (310 questions, 25.9%), Sexual Culture (230, 19.2%), Concept of sex (125, 18.0%), Changes of Puberty (172, 14.4%), Sexual Health (119, 10.0%), Anatomy and Physiology of Reproductive System (78, 6.5%) and Sexual Tendency and behavior (71, 5.9%). 4. 'Reproduction' was the most frequently raised questions not only by both sex groups but also by the 5th grade students. Both sexes in the 4th grade showed the highest interest in Sexual Culture while it was Changes in Puberty for the both sexes in the 6th grade. The knowledge need on sex of the children indicated what they understand sexuality. They apprehended sex as sex, gender and sexuality in an inclusive way. They showed a major interest in the biological sex and the sexual activities. It seems that the children managed to understand clearly the meaning of gender, furthermore, they even pointed out that the streotyped sex role, patrimonial system and the sexual discrimination were unreasonable. The students possessed not only the least but also the most negative understanding in regard of sexuality. Two suggestions were made from the above conclusions for the practical sex education as well as its research. 1. For the practice: The sex education for the elementary upper grade school student should be relevant with their cognitive characteristics, also it should be more specific on the reproductive organs of both sexes, the actual scenes of the pregnancy and child delivery procedures. The gender concept should be added to the biological sex education, which will lead them to understand the unreasonableness of today's male-superior phenomenon and correct them. It is also necessary to develop educational programs for this age group so as to help them to understand sex in the sense of sexuality as well. 2. For the research: It is not easy to draw out a through conclusion since this study was carried out as one-time data collection. Yet it is undeniably helpful for the sex education if we can understand what the children want to know about sex, how much they know about it by conducting deep-interview researches through a small number of sample.

The spawning and growth of eightspine stickleback,Pungitius sinensis kaiborae (Tanaka, 19151, were investigated in the Chavang Stream from March 1990 to february 1991 as a part of study on its life history. Nest building, spavming and parental behaviors were similar to those known on the sticklebacks of Europe, North America and Japan. Bht f sinensis kaibarae in the Chayang Stream, peculiarly, showed only superficial gluing behavior in nest building phase and made two nurseries iust behind the nest in Parental Phase. The individuals with fully mature eggs were found from late February to late June. The fecundity of an adult female was about 21 to 110 (mean 47.07) eggs and the diameter of kllv matured ovarian eggs ranged 1.3 to 1.5 mm. The smallest female with fully mature eggs was 25.8 mm in body length and had 21 eggs. The relationship between the number of mature eggs in ovary and body length was No. of eggs = 2.857BL -55.134 (r = 0.890). The number of deposited eggs in a nest was 27 to 637 and thew were composed of several clusters of various developmental stages. The distribution pattern of gonadsomatic index (GSl) against the body length shown that in females 1+ year-old fishes mainly participate in spawning but in males 11 and 2+ year-old fishes equally participate. From the fluctuat지n pattern of GSI and the number of mature eggs in ovary, it was assumed that the spawning season was from February to June and the peak of spawning was early March to late April. The newly hatched vouns was found at late April and their body length was about 10 mm. The vouns (O+) grew rapidly until late August. Then their srowth was slowed down and finallY ceased in midautumn. The young reached about 35 mm BL in their first year of life. The halting of growth was lasted to next Sune when the spawning season would be nearly closed. They (1+) began to grow asain from late june, grew rapidly until tate september and reached about 415 mm BL. Then there was no more grouvth until to die as 2+ yearold fish. Therefore it was assumed that the life span of P. sinensis kaibarae in the Chavang Stream would be about ko years. The relationship between the body length and the body weight was logBW = 2.9541ogBL -4.802 (r = 0.998).
