Premature ejaculation is the most common sexual dysfunction seen in the male, and it is found in 30 to 50% adult male population. It is defined as the inability to control the ejaculatory process for a sufficient length of time during intravaginal containment to satisfy his partner in at least fifty percent of his coital connections The majority of men with premature ejaculation have underlying psychologic origin of performance-anxiety type, but it is not always psychogenic and may also be a presenting symptom in certain organic disorders. In oriental medicine, the point of treatment of premature ejaculation is recovery of the good ejaculatory control, and the treatment can be approached in three ways as psychological therapy involving behavioral therapy, herb drugs, and acupuncture. This study has aims to investigate and summarize the current trend of treatment for premature ejaculation so as to suggest the effective and available way to treat the disease.

Objective: We aimed to investigate the prevalence of erectile dysfunction (ED) and the usage of phosphodiesterase type 5 (PDE5) inhibitors for ED treatment in infertile couples. Methods: A total of 260 male partners in couples reporting infertility lasting at least 1 year were included in this study. In addition to an evaluation of infertility, all participants completed the International Index of Erectile Function (IIEF)-5 questionnaire to evaluate their sexual function. The participants were asked about their use of PDE5 inhibitors while trying to conceive during their partner's ovulatory period and about their concerns regarding the risks of PDE5 inhibitor use to any eventual pregnancy and/or the fetus. Results: Based on the IIEF-5 questionnaire, 41.5% of the participants (108/260) were classified as having mild ED (an IIEF-5 score of 17-21), while 10.4% of the participants (27/260) had greater than mild ED (an IIEF-5 score of 16 or less). The majority (74.2%, 193/260) of male partners of infertile couples had a negative perception of the safety of using a PDE5 inhibitor while trying to conceive. Only 11.1% of men (15/135) with ED in infertile couples had used a PDE5 inhibitor when attempting conception. Conclusion: ED was found to be common in the male partners of infertile couples, but the use of PDE5 inhibitors among these men was found to be very low. The majority of male partners were concerned about the risks of using PDE5 inhibitors when attempting to conceive. Appropriate counseling about this topic and treatment when necessary would likely be beneficial to infertile couples in which the male partner has ED.

The purpose of this study was to investigate high school students' perceptions of biotechnology. Participants in this study were 9th and 10th grade students who were enrolled in high schools in Gyeonggi Province. The survey instrument used in this study was a 26-item questionnaire that was designed to measure students' perceptions regarding biotechnology. The study revealed that students' perceptions were positive toward the use of biotechnology on biological objects such as plant, grain and microbes. However, their perceptions were negative toward the use of biotechnology on humans and animals. Male students' perceptions were more positive than female students and there were significant differences between male and female students(p<.01). The study also revealed that male and female students had positive perceptions about the use of biotechnology in the development of beneficial products. However, male students' perceptions were more positive than female students(p<.01). Female students' perceptions were slightly more negative than males and they indicated a measure of caution in the development of beneficial products using biotechnology. Regarding the reliability of biotechnological information acquired from food companies, TV broadcasters, and entertainers, male and female students tended to be highly negative. Students perceived that environmental, religious and ethical issues did not affect the use of biotechnology when asked the effect of these factors on the use of biotechnology. They perceived that food safety and genetic factors of microbes did affect the use of biotechnology. Thus, the study findings suggest that teaching and learning strategies based on the differences of perceptions between male and female students of this study be established and the use of media, development of teaching method and materials be promoted in order to enhance student's performance in environmental education.

"Beijijiufa" is a book written by Wenrenqinian, 1226, Song dynasty. It provides moxibustion on acute disease. However, the book is composed with quotations by other authors such as Gehong, Zhenquan, Sunzhenren, Hwangdi Qibo and others. Sunzhenren is a dominant author out of them by quotations. 14 diseases out of 22 in acute disease, is quoted in "Qianjinfang" of Sunzhenren. I will compare texts of "Beijijiufa" with "Qianjinfang" and try to figure out differences between them just like text itself, methods of treatment, moxibution point, number of points, case of male or female and so on. As a result, comparing with "Qianjinfang", "Beijijiufa" has somehow new opinions about acute disease by moxibution in methods of treatment, moxibution point, number of points, case of male or female etc., even if it referred "Qianjinfang".

The locus coeruleus(LG) is known to be observed a sexual dimorphism in rat CNS. LC is the largest collections of norepinephrine(NE)-containing neurons in the mammalian brain. Especially in rat, all LC neurons contained NE unlike other mammalians, so that specific reactions were found in the tyrosine-hydroxylase(TH) immunoreactive neurons. Sexual dimorphism of rat LC has affected by genes before sex hormone appeared, thereafter affected by sex hormones. In these day, many scientists founded morphological differences between male and female LC morphology, but differences of entire structure was not founded. Thus we investigated sex differences of the LC neuron's morphology in rat by three-dimensional(3-D) reconstruction using Confocal laser scanning microscopy(CLSM). We reported that neuron's shape was relatively-large multipolar neurons and neuron's processes in dorsal LC proceeded to ventral direction in the male and female rat. Male had a longer anterior-posterior length than female had in dorsal LC. In addition to middle-LC, male rat's LC had a more thicker posterior region but had not viewed in a previous study. In reverse, female rat's LC had a thicker anterior region like a previous study. This results using 3-D reconstruction by CLSM showed that the male's LC was more wide-ranging than female's relatively.

The purpose of this study was to assess the nutritional status of Korean workers with occupational exposure to lead by estimating nutrients and flood intakes so that we can eventually establish the dietary guidelines to be recommended for the lead workers. Food consumption survey was conducted by a 24-hr recall method with 135 lead workers and 50 non-exposed controls. Food intake data were convened into nutrients intake using computer aided nutritional analysis program. Mean daily energy intake and percentage of recommended daily allowance (RDA) of male lead workers were 2138 local and 87% of RDA while those of control were estimated as 2234 kcal and 91% of RDA. Mean daily intakes of nutrients of male lead workers were 78 g (111% RDA) for protein 502 mg (71% RDA) for calcium, 11.7 mg (97% RDA) for iron, 665 $\mu$g R.E (95% RDA) for vitamin A, 1.39 mg (108% RDA) for thiamin, 1.14 mg (77% RDA) for riboflavin, 15 mg N.E (92% RDA) for niacin and 66 mg (94% RDA) for vitamin C. On average, male lead workers showed significantly lower protein, calcium, iron, sodium, potassium, niacin and vitamin C intakes than control group while cholesterol intake of the male lead workers was significantly higher than that of control group. Intakes of calcium of male lead workers were Less than 75% RDA meaning that nutritional intake of calcium of male lead workers was insufficient and could possibly result in nutritional deficient. Some food groups such as milk, meat and fish must be strongly suggested to improve nutritional status of lead workers. Continuing nutrition monitoring and appropriate nutrition intervention for lead workers most be conducted further.

This study was performed in order to investigate dietary habits, health related lifestyle and blood cadmium and lead levels in female college students. 80 college students (43 males and 37 females) participated in the survey questionnaires. Body weight and height, blood pressure, and body composition were measured. The systolic blood pressure of male and female students were $128.9{\pm}13.9$ and $109.8{\pm}12.0$, respectively. The diastolic blood pressure of male and female students were $77.1{\pm}10.3 $and $66.0{\pm}6.9$, respectively, showing that male students had significantly higher blood pressure than female students (P < 0.001). The BMI of male and female students were $23.4{\pm}3.3$ and $20.2{\pm}2.3$, respectively. Most male students were in the range of being overweight. The dietary habits score of female students was significantly higher than that of male students (P < 0.01).The blood cadmium level of male and female students were $0.54{\pm}0.23$ and $0.52{\pm}0.36$, respectively. There was no significant difference between male and female students. The blood lead level of male and female students were $1.09{\pm}0.49 $and $0.59{\pm}0.45$, respectively. The blood lead level of male students was significantly higher than that of female students (P < 0.001). The blood cadmium level of smokers and nonsmokers were $0.69{\pm}0.29 $and $0.49{\pm}0.29$ respectively (P < 0.05). The blood cadmium level of smokers was significantly higher than that of nonsmokers (P < 0.05). The blood lead level of smokers and nonsmokers were $1.09{\pm}0.43$ and $0.80{\pm}0.54$, respectively. The blood lead level of smokers was significantly higher than that of nonsmokers (P < 0.05). Therefore, proper nutritional education programs are required for college students in order to improve their dietary and health related living habits.
