Purpose: The purpose of this study was to evaluate possible differences in the location of the inferior alveolar canal in male and female Egyptians. Materials and Methods: This cross-sectional retrospective study involved the evaluation of 210 CBCT scans of Egyptian individuals (18-70 years old). The inferior alveolar canal was localized by measuring 8 linear dimensions: 2 for the vertical localization of the mental foramen (superior and inferior to the mental foramen), 4 at the first molar bifurcation for the vertical and horizontal localization of the inferior alveolar canal (superior, inferior, buccal, and lingual to the inferior alveolar canal), and 2 for the horizontal localization of the mandibular foramen (anterior and posterior to the mandibular foramen). The measurements were statistically analyzed via comparative analysis, stepwise logistic regression, and receiver operating characteristic (ROC) curve analysis. Results: Six of the 8 measured distances differed to a statistically significant extent between the sexes. Regression analysis suggested a logistic function with a concordance index of 84%. The diagnostic accuracy capabilities of the linear measurements as sex predictors were calculated using ROC analysis, and the 6 best predictors for sex determination were selected and ranked from highest to lowest predictive power. Moreover, combining these 6 predictors increased the predictive power to 84%. Conclusion: The location of the inferior alveolar canal in the Egyptian population varies significantly by sex; accordingly, this anatomic landmark could be used as a reliable indicator of sexual dimorphism.

Purpose: The purpose of this study was to examine the level of knowledge and learning needs of patients with a permanent pacemaker implantation. Methods: The participants were 86 patients with a permanent pacemaker implantation. Data were collected during April and May 2002 using a questionnaire survey on knowledge and level of learning need. The collected data were analyzed using the SAS program. Results: 1. The average knowledge score was 13.21. The knowledge level was significantly higher in participants under 50 years of age and for those with higher levels of education. The items with the highest knowledge score was 'permanent pacemaker needs regular check ups' and the lowest, 'a bath can be taken 1 month after stitches are removed'. 2. The total average score for learning needs was 60.78 and the mean item score was 3.04 as measured on a 4-point Likert scale. The item showing the highest learning need was 'electrical fields can affect the pacemaker's function and the lowest learning need was for sexual activity after permanent pacemaker implantation'. Conclusion: According to the above findings, it can be concluded that an intensive nursing education program should be developed for patients with a permanent pacemaker especially for those patients over 50 years of age and those with lower levels of education.

Sleep deprivation is an extremely common event in today's society. It has caused learning cognitive skill deterioration and poor concentration, increased disease such as heart disease, diabetes and obesity, sexual function decrease, infertility increase, depression and autonomic nervous system disorder. Sleep deprivation-induced stress caused NADPH oxidase and oxidative stress. And this oxidative stress induces apoptosis. Lilii bulbus and Nelumbins semen are known to mental and physical relaxation effects. In this study, we induced sleep deprivation(SD) in Sprague-Dawley rats in water for 5 days and thereafter administered orally L. bulbus and N. semen for 5 days. Brain tissues were observed by histochemical, immunohistochemical and tunel staining. The immunoreactives of Tumor necrosis factor ${\alpha}$, Neuronal nitric oxide synthases, Phospho-SAPK/JNK and gp91-phox of the L. bulbus administered group and N. semen administered group were weaker than those of sleep deprivation group. In the L. bulbus administered group and N. semen administered group, apoptosis was decreased than that of sleep deprivation group. Proapoptotic p53, Bax, Cleaved caspase 3 immunoreactives of the administered group were weaker than those of sleep deprivation group, whereas anti-apoptotic Bcl-2 immunoreactity was stronger in the L. bulbus administered group and N. semen administered group. Antioxidant mechanism such as DJ-1, superoxide dismutase 1, Nuclear factor-like 2 immunoreactives of the L. bulbus and N. semen administered group were stronger than those of sleep deprivation group. These results demonstrate that L. bulbus, N. semen had the neuroprotective effects on the sleep deprivation-induced oxidative stress in the hippocampus.

Intractable pain arising from disorders of the viscera and somatic structures within the pelvis and perineum often poses difficult problems for the pain pratitioner. The reason for this difficulty is that the region contains diverse anatomic structures with mixed somatic, visceral, and autonomic innervation affecting bladder and bowel control and sexual function. Clinically, sympathetic pain in the perineum has a distinctly vague, burning, and poorly localized quality and is frequently associated with the sensation of urgency. Although various approaches have been proposed for the management of intractable perineal pain, their efficacy and applications are limited. Historically, neurolytic blockade in this region has been focused mainly on somatic rather than sympathetic components. The efficacy of neurolytic ganglion impar block has been demonstrated in treating perineal pain without significant somatovisceral dysfunctions for patient with advanced cancer in 1990. The introduction of superior hypogastric plexus block in 1990 demonstrated its effectiveness in patients with cancer related pelvic pain. In our report, five patients had advanced cancer (rectal caner 3; cervix cancer 1; metastases to sacral portion of renal cell cancer 1). Localized perineal pain was present in all cases and was characterized as burning and urgent with 9~10/10 pain intensity. After neurolytic block of ganglion impar, patients experiened incomplete pain reduction (7~8/10), as determined by the VAS (visual analogue scale), and change in pain site. We then treated with superior hypogastric plexus block, which produced satisfactory pain relief (to less than 4/10), without complication.

This paper describes reproduction, population structure, growth and size at sexual maturity of a deep-water mud shrimp (Solenocera melantho) in the adjacent waters of Geomun Island, Korea. The shrimp was caught by a beam trawl from November 1998 to December 1999. Spawning period was estimated by gonadosomatic index to be from August to early November with a peak in October to early November. Female shrimps were $12\%$ matured at 16 mm in carapace length, $33\%$ matured at 18 mm and $75\%$ matured at 22 mm. The size at $50\%$ maturity for female was estimated to be 20.65 mm in carapace length. Breeding season was estimated to be from August to early November with a peak in October to early November. The size at $50\%$ inseminated was 19.81 mm CL. The fecundity was 87,500-405,200 and related exponentially to carapace length and total weight. This species survived between 25 and 26 months. The maximum carapace length of females and males were 48 mm and 34 mm respectively. Sex ratio was $51.3\%$, and the females were preponderant. Growth was estimated by modified von Bertalanffy growth function incorporating seasonal variation in growth in both years females (K=1.019/yr and $L_{\infty}$=51.731 mm CL) grew faster, reaching a larger size at a given age than males (K=1.848/yr, and $L_{\infty}$=27.499 mm CL). This is indicated by differences in growth performance indices $(\varphi')$ between females (3.291) and males (3.145).

The purpose of this study was to describe physical health and depression status, as well as to assessing factors that influence the physical health status. Method: The data was collected from July to August 2000. Study participants were 252 community-dwelling elderly who were recruited from 10 senior centers located in Seoul, Korea. Their physical health status was measured using the Physical Health Status Measurement Scale developed by Choi and Jung (1991), and depression was measured using BDI-II developed by Beck et al. (1996). Results: 1) The physical health status score was 4.00 $\pm$0.68 (range :1- 5). The sub-dimension that showed the highest score was personal hygiene ability at 4.62$\pm$0.95, and the lowest score was sexual function at 2.20$\pm$1.38. 2. The depression score was 17.99+9.79 (range : 0-63). Regarding the sub-dimensions, the depression scores were higher in the domain of interest with sexuality, general weakness, difficulty in concentration, and fatigue. 3. Deeper levels of depression were correlated with a declining physical health status. 4. The most influential factor on physical health was depression, and the explaining variance was 31.68%. Conclusion: It is concluded that elder subjects in senior centers had fairly good physical health and self-care ability. Also, they did not have significantly high levels of depression. Therefor, health promotion of elderly, it is recommended that elder individuals should be regarded as a respectful and useful segment of our society. Along with this basic concept, there should be a social milieu that does not snow prejudice. Moreover, health care professionals should give more attention to helping the elderly achieve a minimal level of ALD, and, particularly, to raise sexuality and help energize the lives of elder individuals.

Pulmonary embolism from metallic mercury is rare. It may occur after a deliberate intravenous injection of mercury as a suicide gesture, in the presence of drug abuse or severe psychiatric disturbance, with the hope of increasing athletic and sexual performance, and accidentally during right heart catheterization while sampling blood with mercury containing syringes. We have experienced the first case of pulmonary embolism associated with intravenous mercury injection in Korea. The blood mercury level remain elevated within the toxic range to date. This may be due to the continued absorption of embolized mercury. Multifocal areas of patchy perfusion defects are in both upper lung fields on perfusion scan of lung. Few of the abnormalities of respiratory or renal function reported previously were demonstrated. We report the case of a young male patient presenting with a clinical picture of pulmonary embolism, in whom widespread deposit of metallic mercury were demonstrated throughout both lungs and elsewhere in the body.

The major findings of basic women wear in genre painting were ; 1. Due to the influence of Shill-Hak (practical science) philosophy, Jeogori became shorter and a tighter fit came to be the norm. 2,. The shortening of the Jeogori influenced a longer Chima with a wider span providing comfort in movement or at work. The end of the skirt was often held by one hand to the waist adding to comfort. This was called the Go-dul-chima(Lifted Chima). 3. Because the Geo-dul-chima exposed a portion of one underwear at the bottom of the dress this influenced the "irnamentation' of underpants and underskits. 4. Collars or lapels came in the form of Dang-ko, Kal, Mok-pan and Ban-Mokpan. Among there Dang-ko style collars were the most common which allows us to conclude that this was the most popular. 5. The most commonly used colors for Jeogori were white (39.8%) and jade(18.3%) . The most commonly used colors for CHima were deep blue(34.4%) and jade(20.4%) . The lower Chima used the darkercolors to give stability to the overall costume. 6. Clothing had the function of differentiating the classes. Only the Yang-ban were allowed to wear the Samhijang Jeogori and the Gob-Chima(double layered Chima) and the knotting of the Chima to the left. But the painting show that these rules were not adhered to in the strictest manner. With the bases of these types of chima and Jeogori can look at the characteristical beauty of the ordinary women during the late Cho-sun dynasty. First is the beauty which comes from mystery of those parts of body which can not be seen. A sense of subtle and sensual beauty as well as that coming from the enlargement of reduction of the upper body, narrow waist and abundant lower body parts creating an ideal silhouette of sexual charm. An expression of emotion through clothing by those who lived during those times.

Scientific evidence for the primary prevention of cancer caused by physical activity of regular moderate-intensity or greater is rapidly accumulating in this field. About 300 epidemiologic studies on the association between physical activity and cancer risk have been conducted worldwide. The objectives of this paper were three-fold: (i) to describe briefly the components of physical activity and its quantification; (ii) to summarize the most important conclusions available from comprehensive reports, and reviews of the epidemiologic individual and intervention studies on a role physical activity in cancer prevention; (iii) to present proposed biological mechanisms accounting for effects of activity on cancer risk. The evidence of causal linked physical activity and cancer risk is found to be strong for colon cancer - convincing; weaker for postmenopausal breast and endometrium cancers - probable; and limited suggestive for premenopausal breast, lung, prostate, ovary, gastric and pancreatic cancers. The average risk reductions were reported to be 20-30%. The protective effects of physical activity on cancer risk are hypothesized to be through multiple interrelated pathways: decrease in adiposity, decrease in sexual and metabolic hormones, changes in biomarkers and insulin resistance, improvement of immune function, and reduction of inflammation. As there are several gaps in the literature for associations between activity and cancer risk, additional studies are needed. Future research should include studies dealing with limitations in precise estimates of physical activity and of a lack of consensus on what defines sedentary behavior of individuals and those linked with the proposed biomarkers to cancer risk and controlled exercise intervention trials.
