The purpose of this study is to compare the sexual behaviors of breast cancer survivors (BCS) with women without breast cancer (WWBC) and provide basic data to develop education program for patients before surgery. The study sample included 215 subjects: 140 women without breast cancer and 75 women diagnosed at least six months previously with breast cancer. Data were collected using the Wilmoth's Sexual behaviors Questionnaire-F that consisted of 50 items measuring sexually: communication, sexual techniques, sexual responses, body scare, self-touch, relationship quality, and masturbation. All items were scored on a 6-Likert scale with high scores reflecting high levels of the specific sexual behaviors. The reliability of this instrument was .91(Cronbach‘s alpha). Data were collected during the period from September 1 to September 30, 2001. The collected data were analyzed using t-test, Chi-square, ANCOVA with SPSSwin program. The scores of a sample of WWBC were compared to those of BCS and the scores of BCS were compared by type of surgery and period since surgery. The results were as follows: 1. No differences in sexual behaviors were found between BCS and WWBC, but, differences were found in communication, sexual technique, and relationship quality depending on the period since surgery. 2. Mean Score of BCS' communication in sexual behaviors was significantly lower than that of the WWBC. 3. Sexual behaviors scores of BCS with Menopause, lumpectomy, long duration since surgery showed significantly higher than that of the others. In conclusions, BCS returned to the normal sexual behaviors according to period since surgery. The program of the sexual counseling for patients before surgery should consider this result in the future.

It is thought that the quantity and quality of the heat stimulation and the mechanism of heating process are important to understand the moxa-combustion. In order to get the basic data on the effective moxa-combustion method, combustion temperature changes (average temperature, peak temperature, average gradient temperature and maximum gradient temperature) of the heating period were measured respectively by the density of moxa material. For the experiment, samples of $300mg/0.26cm^3$ , $400mg/0.26cm^3$ and $500mg/0.26cm^3$ of moxa material were molded in a conical mold with each 10mm in diameter and height. 1. The average temperature and peak temperature of heating period on the moxa-combustion showed higher in the $400mg/0.26cm^3$ and $300mg/0.26cm^3$ than in the $500mg/0.26cm^3$ sample respectively. 2. The average gradient temperature of heating period on the moxa-combustion rose quickly in the $300mg/0.26cm^3$, $400mg/0.26cm^3$ and $500mg/0.26cm^3$ in that order and the maximum gradient temperature rose more quickly in the $300mg/0.26cm^3$ and $400mg/0.26cm^3$ than in the $500mg/0.26cm^3$ sample respectively. According to the above results, it is concluded that the density of moxa material is (the) more important (factor) than the weight or volume of moxa material on the combustion temperature changes of the heating period for the evaluation of the quality and quantity of moxa-combustion.

Our previous research on coprolite specimens from the mummies of Joseon Dynasty (1392-1910 CE) has revealed various species of parasite eggs. Herein, we added 2 new helminthic cases of human remains from Joseon-period graves in the Republic of Korea (Korea). The organic materials precipitated on the hip bones of 2 half-mummied cases (Goryeong and Gwangmyeong cases) were collected, rehydrated, and examined by a microscope. In the sample from Goryeong-gun (gun=County), ova of Trichuris trichiura, Clonorchis sinensis, and Metagonimus spp. were detected, and eggs of T. trichiura and A. lumbricoides were found from the sample of Gwangmyeong-si (si=City). By adding this outcome to the existing data pool, we confirm our previous estimates of Joseon-period parasite infection rates. The overall rates of A. lumbricoides, T. trichiura, and C. sinensis decreased dramatically from Joseon to the modern period. In Goryeong mummy specimen, we also found Metagonimus spp. eggs that has rarely been detected in archaeological samples so far.

Objectives: Yonnyuniksoogobon-dan (Yan Nian Yi Shou Gu Ben Dan 延年益壽固本丹) is composed of 11 herbs (Polygoni Mutiflori Radix, Lycii Radicis Cortex, Polia, Rehmanniae Radix, Rehmanniae Radix Preparat, Asparagi Radix, Liriopis Tuber, Lycii Fructus, Acori Graminei Rhizoma, Angelicae Acutiloba Radix, and Pini Folium) based on Yonryunggobon-dan (Yan Ling Gu Ben Dan 延齡固本丹) and Yonnyuniksoobulrho-dan (Yan Nian Yi Shou Bu Lao Dan 延年益壽不老丹). This study evaluated hair growth promoting effect of Yonnyuniksoogobon-dan on the shaved C57BL/6 mice. Methods: Yonnyuniksoogobon-dan was treated by oral administration (Sample I) and oral administration plus skin application (Sample II) once a day for 12 days. Hair regrowth was photographically and histologically determined during the experimental period. Hair growth cycle related factors (EGF, TGF-${\beta}1$) and vascular factors (VEGF, iNOS) were also determined with immunohistochemistry. Results: 1. On gross observation of hair regrowth, Sample I and Sample II groups demonstrated acceleration of hair regrowth. 2. The hair regrowth index of the Sample I group increased significantly from 7 days (P<0.05) to 12 days (P<0.01) after the shave while that of the Sample II group significantly increased at 12 days (P<0.05). 3. On histological observation, both Sample I and Sample II groups demonstrated histological improvement and increases of number and diameter of the hair follicles. 4. EGF expressions on the root sheath of hair follicles were up-regulated in both Sample I and Sample II groups. 5. TGF-${\beta}1$ expressions on the root sheath of hair follicles were not regulated in Sample I or Sample II groups. 6. VEGF expressions in the surrounding tissues of hair follicles were up-regulated in both Sample I and Sample II groups. 7. iNOS expressions in the surrounding tissues of hair follicles were down-regulated in both Sample I and Sample II groups. Conclusions: These results suggest that Yonnyuniksoogobon-dan has hair growth-promoting activity and these effects relate to up-regulations of EGF and VEFG expressions and down-regulations of TGF-${\beta}1$ and iNOS expressions on hair roots.

This study investigates the causal relationship between stock prices and exchange rates for six Middle Eastern countries, namely, Egypt, Iran, Jordan, Kuwait, Oman, and Saudi Arabia before and during (after) the 2007 global financial crisis for the period between January 2004 and September 2015. The sample is divided into two sub-periods, that is, the period from January 1, 2004 to September 30, 2007 and the period from October 1, 2007 to September 30, 2015, to represent the pre-crisis period and the post-crisis period, respectively. Using Vector Autoregressive (VAR) model in a multivariate framework (including two control variables, inflation rates and oil prices) the results suggest that in the case of Jordan, Kuwait and Saudi Arabia, there exists bidirectional causalities after the crisis period but not the before. The opposite status is available for the case of Iran. In the case of Oman, there is bidirectional causality between the variables of interest in both periods. The results also reveal that the relationship between stock prices and exchange rates has become stronger after the 2007 global financial crisis. Overall, the results of this study indicate that fluctuations in foreign exchange markets can significantly affect stock markets in the Middle East.

The Korean government has introduced and enforced maritime traffic safety assessment to secure traffic safety since 2010. The maritime traffic safety assessment is needed by law to design a new port or modify an existing one. According to Korea Maritime Safety Act, in the assessment the propriety of marine traffic system consists of the safety of channel transit and berthing/unberthing maneuver, safety of mooring, and safety of marine traffic flow. The safety of channel transit and berthing/unberthing maneuver can be evaluated only by ship-handling simulation. The ship-handling simulation is carried out by sea pilots working with the port concerned. The vessel's proximity measure is an important factor to evaluate traffic safety. The proximity measure is composed of vessel's closest distance to channel boundary and probability of grounding/collision. What is more, the probability of grounding becomes important. According to central limit theorem, a sample has a normal distribution on condition that its size is more than 30. However, more than 30 simulation runs bring about the increase of assessment period and difficulty of employing sea pilots. Therefore this paper is to find out minimum sample size for evaluating vessel's proximity. First sample sets of size of 3, 5, 7, 9 etc. are selected randomly on the basis of normal distribution. And then KS test for goodness of fit and t-test for confidence interval are applied to each sample set. Finally this paper decides the minimum sample size. As a result this paper suggests the minimum sample size of 5, that is, the simulation of more than five times.

The formation and transition of 2212 and 2223 phase have been studied in BPSCCO system. The 2212 phase formed in early sintering state reacts on $Ca_2PbO_4,\;Ca_2CuO_3$ and CuO during sintering process and thus produces the 2223 phase. A long sintering period is need to fabricate the superconductor with large volume fraction of 2223 phase. Also, the thin plate-like grains composed of Bi, Sr, Ca and Cu contribute to 2223 phase formation. Though the sample has lower volume fraction of 2223 phase, the critical temperature is measured highly in case of the grain grown to plate-like shape. In this work, the critical temperature of the sample sintered for 264 hr in air was measured 108 K. Microstructure of the sample was varied with condition of heat treatment after sintering process and the sample annealed with $500^{\circ}C$ for 5 hr showed excellent charateristics of 2223 phase formation.

The conventional optics and near field optics are compared numerically in the view points of the spot size and propagation characteristics. The decaying characteristics of near field light require the optics to access the object within several tens of nanometers. Therefore the gap control is one of the main issues in the near field optics area. In this paper the gap control is done by using the shear force of the NF(Near Field) probe and the characteristics are examined. The probe is modeled as a 2'nd order mass-spring-damper system driven by a harmonic force. The primary cause of the decrease in vibration amplitude is due to the damping force - shear force - between the surface and the probe. Using the model, damping constant and resonance frequency of the probe is calculated as a function of probe-sample distance. Detecting the amplitude and phase shift of the NF probe attached to the high Q-factor piezoelectric tuning fork, we can control the position of the NF probe about 0 to 50nm above the sample. The feedback signal to regulate the probe-sample distance can be used independently for surface topography imaging. 3-D view of the shear force image of a testing sample with the period of $1{\mu}m$ will be shown.

This study was designed to investigate the antihyperlipidemic activity of Fermented Rhus Verniciflua Stokes Extract(FRVSE) on diet-induced hyperlipidemia in rats. The animals were divided into 4 groups of the normal group(fed with normal diet), control group(fed with high fat diet), sample A group(fed with high fat diet and medicated FRVSE 192 ㎎/㎏/day), sample B group(fed with high fat diet and medicated FRVSE 384 ㎎/㎏/day), and received oral administration of each prescription with diet for a period of six weeks. The changes in the body weight, the liver weight, the epididymal fat weight, and the plasma levels of total cholesterol, triglyceride(TG), high density lipoprotein(HDL) cholesterol and low density lipoprotein(LDL) cholesterol were measured. In sample A group, the weight of liver and plasma level of TG decreased significantly. There was a significant decrease in the plasma level of total cholesterol, TG and LDL cholesterol in the sample B group. These results suggest that the FRVSE have a good antihyperlipidemic activity and a potential to treat hyperlipidemia.
