This study aimed to figure out the characteristics and trends of female images in domestic cosmetic ads, in regard to the introduction and change of the feminism. To begin with, 86 TV commercials of Mamonde cosmetic brands, aired from 1991 to 2019, was analysed in both quantitative and qualitative method. In result, in the first period (1991~1997), the radical feminism was predominant, insisting equality with males. But in the second period (1998~2005), it returned to the liberal feminism in which conventional female images remains. In the third period (2006-2011), the feminism and the post feminism appeared to be mixed, while, in the fourth period (2012-2019), the post feminism has become remarkable where females actively pursue the beauty. To summarize, it is meaningful in academic aspect that the result is a case study which vertically examined the female images of one single cosmetic brand in terms of feminism, on the other hand, in practical aspect that they suggest the establishment of communication and creative strategies of female products.

Purpose: Malignant melanoma is a fatal tumor arising in the melanocytic systems of the skin. The incidence of malignant melanoma, formerly considered a rare tumor in Korea, is observed to increase. The aim of this study is to analyze the clinical and histopathological pattern of malignant melanoma in one institute. Methods: Thirty patients with ages ranging from 33 to 80 years, diagnosed as malignant melanoma at our skin tumor department, were enrolled in a retrospective study over a 6 year period(2000. 9-2006. 7). The analyzed data included age, sex, location, duration before diagnosis, clinical type, level of invasion, and stage. Results: The cases were identified and analyzed by clinical and histopathologic study. The male to female ratio was 1:1.7. Lower extremities(especially, feet) were favored sites. The majority of cases were acral lentiginous melanoma(40%), followed by nodular melanoma (36.7%), superficial spreading melanoma(20%) in this study. Clark level IV was predominant in histopathologic study. There was merely narrow gap among each stage by AJCC. Conclusion: The clinicopathological characteristic of melanoma in our patients is quite different with that in the West. In this retrospective study, primary lesions of the foot were predominant with melanoma, and a high percentage of these were classified pathologically as acral lentiginous melanomas. Patients had a more advanced stage of disease at first presentation and a more deeply invasive primary lesion than Western patients. These suggest that malignant melanoma has a worse prognosis in our patients than in the West. So, further organized prospective studies are needed to approach the prudent and accurate diagnosis and management of melanoma in Korea.

This research was conducted to evaluate fungal and bacterial populations in unhulled and brown rice under indoor storage conditions, and to examine the relationship between microbial populations and environmental conditions such as temperature and relative humidity. The temperature and relative humidity of the storage room ranged from $22.6^{\circ}C\;to\;27.0^{\circ}C$ and 23.3% to 44.2%, respectively. Total fungal and bacterial populations remained relatively stable over the storage period. Predominant fungi included Aspergillus candidus, A. flavus, A. fumigatus, and Penicillium spp.; the predominant bacteria were Bacillus, Microbacterium, Sphingomonas, and Methylobacterium spp. Total fungi and bacteria were not significantly correlated with either unhulled (r=0.448, P=0.372) or brown (r=0.466, P=0.351) rice. In unhulled rice, total fungi showed positive correlations with total Aspergillus (r=0.994, P<0.001) and total Penicillium (r=0.906, P<0.05); A. flavus was positively correlated with total Aspergillus (r=0.913, P<0.05) and total fungi (r=0.868, P<0.05). In brown rice, Bacillus spp. was also positively correlated with total bacteria (r=0.998, P<0.001). Mean temperature was negatively correlated with A. candidus (r=-0.852, P<0.05) and total fungi (r=-0.961, P<0.01), and mean relative humidity was positively correlated with total Penicillium spp.(r=0.884, P<0.05) in brown rice. Hence these results could provide basic information on the fungal and bacterial populations in unhulled and brown rice stored under room conditions, and on the effect of environmental conditions on the populations of fungi and bacteria, especially Aspergillus and Penicillium spp.

This study was performed to know whether there is any change of physiological activity in DLMJ which is inoculated by lactic acid bacteria. Lactic acid bacteria were isolated from Dolsan leaf mustard Kimchi (DLMK) at $20^{\circ}C$. In the optimum ripening period, the population of Leuconostoc and Lactobacilli in the DLMK were found to be high. The Leuconostoc, Lactobacilli and Lactococci strains were identified as Leuconostoc mesenteroides, Leuconostoc gelidum, Weissella confusa, Lactobacillus plantarum, Lactobacillus raffinolactis, Lactococcus lactis and Weissella confusa using the Biolog system. The most predominant strain which was isolated from DLMK was Weissella confusa. As the results of the phylogenetic analysis using 16s rDNA sequence, the Weissella confusa turned out to be Weissella kimchii, with 99.0% similarity. To investigated the change of physiological activity in DLMJ by lactic acid bacteria, 7 predominant strains inoculated to DLMJ (Dolsan Leaf Mustard Juice). The cytotoxicity was found to be under $19.55\%$ all cases. Also, the antioxidative activity of the DLMJ treated with lactic acid bacteria was very low, which might have been due to the reduced antioxidative phytochemicals during the preparation of the sterile sample. The ACE inhibiting activity of DLMJ by inoculation with Weissella kimchii was shown to be the highest ($94.0\%$). This could be that the degradation of sulfur containing materials in DLMJ by Weissella kimchii gave rise to ACE inhibiting activity.

The sleep homeostatic response significantly affects the state of anesthesia. In addition, sleep recovery may occur during anesthesia, either via a natural sleep-like process to occur or via a direct restorative effect. Little is known about the effects of isoflurane anesthesia on sleep homeostasis. We investigated whether 1) isoflurane anesthesia could provide a sleep-like process, and 2) the depth of anesthesia could differently affect the post-anesthesia sleep response. Nine rats were treated for 2 hours with $ad$ $libitum$ sleep (Control), sleep deprivation (SD), and isoflurane anesthesia with delta-wave- predominant state (ISO-1) or burst suppression pattern-predominant state (ISO-2) with at least a 1-week interval. Electroencephalogram and electromyogram were recorded and sleep-wake architecture was evaluated for 4 hours after each treatment. In the post-treatment period, the duration of transition to slow-wave-sleep decreased but slow wave sleep (SWS) increased in the SD group, but no sleep stages were significantly changed in ISO-1 and ISO-2 groups compared to Control. Different levels of anesthesia did not significantly affect the post-anesthesia sleep responses, but the deep level of anesthesia significantly delayed the latency to sleep compared to Control. The present results indicate that a natural sleep-like process likely occurs during isoflurane anesthesia and that the post-anesthesia sleep response occurs irrespective to the level of anesthesia.

The main investigation of this thesis is about the comparative analysis of the fashion style preferences in the ages of 20-30 women, according to the style, by researching the area of Dalian and Seoul, represented as outstanding fashion cities in north eastern area. Both taking pictures and recording camcoders were performed at the famous fashion street in Seoul and Dalian. The period of investigation was from 24th of July to 2nd of August 2008. The result of research are as follows. Generally, the casual style was predominant in both area. The jean casual in Seoul was somewhat tidy and conservative, while that in Dalian showed the tendency of boldly exposed their body. In terms of easy casual, T-shirts and mini-tight skirt were preferred in Seoul, while T-shirts and midi-flare skirt was popular in Dalian. In Seoul, the blouse and mini skirt were in vogue, while one-piece dress, blouse and 5/7/9 length pants were prevalent in Dalian, in case of romantic style. The sports casual was relatively low in frequency in both areas, however, it was relatively more popular in Dalian than in Seoul. The frequency of classic style was similar in both areas. The T-shirts/blouse and Chanel-line skirt were preferred in Seoul, while the combination of jacket/shirts and full-length straight pants were preferred in Dalian. The one-piece dress was predominant in feminine style, the combination of mini one-piece dress and shoulder bag prevalent in Seoul, while the combination of Chanel-line one-piece dress designed as boldly exposed body was popular in Dalian, which shows the tendency of sexy, feminine style. The clear contrast or differences of street styles in Seoul and Dalian would become evident by this research. The continuous investigations into the various regions of China would be expected as an important measure for the successful launching into the Chinese fashion market.

Background: This study evaluated the effect of remimazolam and propofol on changes in autonomic nerve activity caused by surgical stimulation during orthognathic surgery, using power spectrum analysis of blood pressure variability (BPV) and heart rate variability (HRV), and their respective associations with cardiovascular fluctuations. Methods: A total of 34 patients undergoing Le Fort I osteotomy were randomized to the remimazolam (Group R, 17 cases) or propofol (Group P, 17 cases) groups. Observables included the low-frequency component of BPV (BPV LF; index of vasomotor sympathetic nerve activity), high-frequency component of HRV (HRV HF; index of parasympathetic nerve activity), balance index of the low- and high-frequency components of HRV (HRV LF/HF; index of sympathetic nerve activity), heart rate (HR), and systolic blood pressure (SBP). Four observations were made: (1) baseline, (2) immediately before down-fracture, (3) down-fracture, and (4) 5 min after down-fracture. Data from each observation period were compared using a two-way analysis of variance with a mixed model. A Bonferroni multiple comparison test was performed in the absence of any interaction. One-way analysis of variance followed by Tukey's multiple comparisons test was performed when a significant interaction was observed between time and group, with P < 0.05 indicating statistical significance. Results: Evaluation of autonomic nerve activity in comparison with baseline during down-fracture showed a significant increase in BPV LF (P < 0.001), an increasing trend in HRV LF/HF in Group P, and an increasing trend in HRV HF in Group R. There were no significant differences in HR or SBP between the two groups. Conclusion: During down-fracture of Le Fort I osteotomy, sympathetic nerve activity was predominant with propofol anesthesia, and parasympathetic nerve activity was predominant with remimazolam anesthesia.

In the modem manufacturing system, to achieve the unmanned automation, the stability of accuracy is required through a long working period. The thermal deformation of precision machine is predominant in this long time stability. While grinding slender and long workpiece at cylindrical grinding machine, we support workpiece using steadies to prevent the vibration of workpiece. The thermal deformation of the machine by grinding and internal heat source cause processing errors, so the steadies for compensating the thermal deformation in real time are strongly needed. In order to compensate these thermal deformation and grinding processing errors, the device to determine the precise positioning having the stroke of 10.mu.m is necessary. This paper suggests design and make the device to determine the precise positioning using thermoelectric device, to investigate the control characteristics and presents the heat actuator will be very useful in machine tool.

In this study we have evaluated daily beverage intake of the inhabitants in Seoul by a 24 hrs. recall procedure from 1145 respondents between pre-school children to adults in the period of June-July 1985. Estimates of consumption were made for each of seven beverage groups and comparisons were made within age, sex and body weight. Significant differences existed for certain beverage in each category analyzed. Total Fluid intake was greater for male than female at all ages and tended to be lower in the older age group with adjustment for differences in body weight. Milk was the major beverage among children while soft drinks were the predominant beverage for teen-ages. Alcoholic drinks represented the smallest component of daily fluid intake among women but were the second largest component of daily fluid levels for men over the age of 24 years.
