This paper aims to compare the scenic images of four ancient Chinese cities including Lijiang, Pingyao, Huizhou and Langzhong, so as to provide specific development strategies for the ancient cities. In this paper, the ancient cities' scenic images are divided into three sub-indexes and eight evaluation dimensions. Based on this, the study first uses Python software to collect tourists' online comments on the four ancient cities. Then, the social network analysis method is used to build a high-frequency keywords matrix of tourist comments and the R language is used to generate a visual network graph. After this, the entropy weight method is used to determine the weights and values of eight evaluation dimensions. Finally, the tourists' overall satisfaction indexes of the four ancient cities are calculated accordingly. The results show that (1) the overall satisfaction of Lijiang is the highest, while that of Huizhou is the lowest; (2) from the weight of each evaluation dimension, it can be seen that tourists care more about the national culture and historical culture; (3) from tourists' satisfaction index on each evaluation dimension of the four ancient cities, we can find that the four ancient cities has their own advantages and disadvantages in tourism development. (4) local tourism-related institutions should strengthen their advantages and improve their deficiencies so as to enhance tourists' overall image of the ancient city.

Several ingredients of kimchi including chinese cabbage, garlic, leek, big green onion, and small green onion were assayed for their chitinase activities. Kimchi with various leek contents (4, 8, 12%) were fermented at 15$^{\circ}C$ for 9 days and the chitinase (EC 3.2.1.14) activity and textural properties were determined. The chitinase activity of the ingredients was in the order of garlic>leek>small green onion>chinese cabbage>big green onion. During fermentation, the chitinase activity of kimchi juice appeared more prominent than that of kimchr tissue, however, it was decreased in all kimchi samples among which the control sample showed a remarkable drop. The activity of chitinase in kimchi tissue increased until 3rd or 5th day of fermentation and then decreased. The puncture force of all kimchi samples decreased and those of leek-added kimchi were higher than those of control. The above results suggested that the addition of leek for kimchi preparation could contribute to the improvement of textural qualities of kimchi due to chitinase activities of leek during fermentation.

Objectives This study was aimed to analyze characteristics of facial shapes in adult women by sasang constitution using hyungsang classification. Methods Using a digital camera, we took a picture of 1,011 women who participated in clinical study on menstrual pain and acquired their 3D facial images with a face-only scanner. They filled out SSCQ-P(sasang constitution questionnaire for patient) for the diagnosis of sasang constitution. Based on the above photographs and 3D images, one of the hyungsang medicine specialist diagnosed according to five diagnostic criteria. The sasang constitution was diagnosed by referring to questionnaires and photographs. Frequency analysis was performed using the statistical analysis system version 9.4 and chi-square test was performed for validity evaluation. Results In taeeumin, the wide face shape(n=261, 74.36%) was much more than the narrow shape(n=90, 25.64%) and the convex face profile(n=164, 85.86%) was much more than the concave profile(n=27, 14.14%). Regardless of sasang constitution, angular face shape(n=501, 50%) was the most, followed by oval shape(n=317, 31.64%). Subjects with big ears(n=291, 29.19%) were the most, while big eyes(n=104, 10.43%) were the least. Subjects with eyes and nose tip upward(n=615, 78.05%) were the most, while eyes and nose tip downward(n=22, 2.79%) were the least. Conclusions Most Korean adult women have angular face, such as square or diamond, with slanted eyes and upturned nose. Taeeumin women have wide facial shape and convex profile.

This paper describes the arousal measurement and control system using fuzzy logic to prevent drowsy driving. Sugeno's method was used for fuzzy inference in this study. Arousal evaluation and control criteria were modified from result of Nz-IRI analysis depending on arousal sate. Membership function and rule base of fuzzy inference were determined from the modified arousal level criteria When lRl (Inter-SIR Interval) was shorter than 60sec, outputs of both methods were changed from small to big, but output of three step warning method was same level until the next warning range. Since output of fuzzy inference tracked well the change of subject's arousal level, problems of three step warning method could be overcome by fuzzy inference method Furthermore, the output of the fuzzy inference was highly correlated with Nz(r = 0.99). Therefore, the fuzzy inference method for evaluation and the control of arousal will be more effective at real driving situation than three step warning method.

The purpose of this study was to investigate the effects of the Science Writing Heuristic (SWH) approach on the students' summary writing, logical thinking and achievements for the course. Participants in this study were 132 female students from a girls' middle school. The SWH approach was used for two experimental classes and the typical teacher-centered instructional approach was used for two comparative classes. Summary writing test, logical thinking test (GALT) and achievement test for the course were administered before and after the instruction period. Results of this study indicated that the SWH approach was helpful for students in finding big ideas, understanding science concepts, developing logical thinking abilities and doing well in the course. This study also implied that the SWH approach was effective for the low achieving students.

Since 2013, adults aged over 20 can receive national health insurance scaling once a year in South Korea. In this study, we analyzed the usage status of national health insurance care service for periodontal disease in 2010-2018 by using Healthcare big data of the Health Insurance Review and Assessment Service. The increase rate of the dental care users was very high at 7.8 and 11.2% in 2013 and 2014, respectively. These are higher than the increase rate of all medical institution users, which is between -1.7 and 3.7%. In 2017, the rate of dental use was 44.4%, which has increased more than 10% compared to 2012. Percent receiver of national health insurance scaling was 19.5% in 2017. The 20s had the highest rate of 23.2%. The rate decreased with age. Based on these results, it can be evaluated that the expansion of national health insurance coverage for scaling improves accessibility to dental care. A more long-term assessment of the effect of periodic dental examination and scaling on reducing the prevalence of periodontal disease is needed. National health insurance coverage should be extended to oral hygiene education and supportive periodontal therapy in order to prevent periodontal disease.

1) An experiment was made at the newly constructed glass house of Chun chan Agriculture callege to find out facts about the late-raising of Cortinellus edodes (Berk) Ido et Imai during the winter season. 2) The host timbers used in this experiment were Quercus Serrata Thumb and Quercus crispulo BI.; 5 years old each, the diameter ranging from 6cm to 17cm, dividing them into 12 diameter groups with 10 timbers in each group. The total number of timbess was 240 in two blocks. 3) As the pre-treatment of host timber, the autumn generation in 1962 was inhibited, and before being put into the glass-house, they were stimulated of generation for 3 days after 3 days, water-soaking. 4) The temperature control was made by using two coal stoves and the humidity control by spraying and two full water tanks. During cloudy weather and night, the green house was covered to preserue constant temperature of $5^{\circ}C{\sim}10^{\circ}C$. 5) The result; Quercus Serrata Thumb. with lesser diameter than 9cm showed no generation either in as big timber as one with diameter 11 cm. On the other hand, too big timbers showed low rate of generation; the reason, at a guess, is the too short period of cultivation and insufficient water soaking and inappropriate temperature. 6) The most standard size of host timber was found out be those with diameter 12cm~15cm in Quercus serrata Thumb, and those with diameter 14cm~17cm in Quercus crispula BI. Quercus crispula seemed to have slightly greater efficiency of generation than Quercus Serrata Thumb., but it could not be concluded as "decisive". Lastly, the host timber used in this experiment were old and the rate of generation was low as a whole.

This paper proposes a RSA crypto-processor for embedded systems. The architecture of the RSA crypto-processor should be used relying on Big Montgomery algorithm, and is supported by configurable bit size. The RSA crypto-processor includes a RSA control signal generator, an optimal Big Montgomery processor(adder, multiplier). We use diverse arithmetic unit (adder, multiplier) algorithm. After we compared the various results, we selected the optimal arithmetic unit which can be connected with ARM core-processor. The RSA crypto-processor was implemented with Verilog HDL with top-down methodology, and it was verified by C language and Cadence Verilog-XL. The verified models were synthesized with a Hynix 0.25${\mu}{\textrm}{m}$, CMOS standard cell library while using Synopsys Design Compiler. The RSA crypto-processor can operate at a clock speed of 51 MHz in this worst case conditions of 2.7V, 10$0^{\circ}C$ and has about 36,639 gates.

Middle aged women these days not only consider themselves as younger than actual, maintain figures and looks of younger women, but also show a big interest to fashion goods as younger generations. The TV media has a big influence on this trend. This study is conducted to figure out how the TV media involvement of middle aged women affects their difference age, youth-pursuing clothing behavior and fashion leadership. After the survey, a total of 326 questionnaires completed by women of their 40s and 50s were used to this analysis. The results are as follows, 1. The highest cognitive age of middle aged women was the look age, and the lowest was the feel age in the 40s, and the interest age in the 50s. And it was shown that the difference age were 7.05 years for the 40s and 9.10 years for the 50s. 2. The TV media involvement had a significant influence on the difference age as its antecedent. And the TV media involvement affected directly the youth-pursuing clothing behavior and fashion leadership. The higher the TV media involvement was, the higher difference age and fashion leadership were shown. 3. The difference age was shown as mediating the TV media involvement and the youth-pursuing clothing behavior, and the TV media involvement and fashion leadership only partially. 4. The youth-pursuing clothing behaviors were influenced by TV media involvement and difference age. Conclusionally, this study revealed that the TV media had a great influence on middle-aged women's clothing behavior, supporting the cultivation theory of TV media.
