An Ola leaf manuscript, which consists of words carved on an Ola leaf and is filled up with a mixture of herbal oils made from Vateria acuminata Hyne and charcoal, is one of the native writing media in Sri Lanka. According to historical records, Ola leaf manuscripts had been used from the 1st to the 18th century A.D. From the recent findings that Ola leaf manuscripts have been preserved well for the past 400 years and are in good state of preservation, it is supposed that herbal oils preserve Ola leaves against environmental and biological factors such as fungi and insects. To evaluate the anti-biological susceptibility of the herbal oils, the molds isolated from wooden printing blocks in Janggyeong Panjeon of Haeinsa Temple in South Korea and bacteria and fungi isolated from Ola leaves were cultured. After spreading the microorganisms suspension on an agar plate, a disk paper containing a certain volume of herbal oil was placed on the agar plate. It was found in the experiment that herbal oil exhibits a clear zone, which is optically clear and inhibits the growth of microorganisms, against some molds and bacteria. The study results indicate that the herbal oil from the plant Vateria acuminata Hyne has the anti-bacterial and anti-fungal properties.

Dalmun was a top star entertainer who enjoyed the greatest popularity in the Chosun Dynasty in the 18th century by performing dance, singing and telling jokes. This study focuses on the fact that there has been no precedent research of actor studies or artist management perspective because he has been discussed only in the fields of literature and history. Therefore, we selected "Dalmunga" written by Hong Shinyu and "Gwangmunjajeon" created by Park Jiwon, which contained the richest expressions of his art world in the old relevant literature, and then analyzed his artistic capabilities using the content analysis method that combine frequency analysis(FA) and semantic analysis(SA) by applying the Actor Evaluation Model developed in 2015. As a result of FA, Dalmun's artistic competence factors (64%) were far more emphasized than artistic achievement factors (36%). It was considered that the atmosphere of Chosun society was reflected under the influence of Confucianism, which emphasized the fostering personality and virtue. According to the SA, a positive view (53.1%) dominated a negative perspective (24.5%) for each of his artistic capability factors. It shows that in contrast to Dalmun's destitute lower-class artist status, his self-abolition and transcendental life have become an inspiration to others. In conclusion, artistic devotion, perfect artistry, good humanity and spirit, commendable words and demeanors that cause'good influence' derived from Dalmun's unique competence are regarded as a key element of self-management, especially for popular artists suffering from recent misbehavior and deviant issues.

Raquel, the representative work of Vicente García de la Huerta, an 18th century Spanish playwright achieved theater box-office success and popularity during staging. It has been evaluated by many scholars and critics as the ideal drama that faithfully followed the norms of neoclassicism, which pervaded the aesthetic mainstream at the time. However, the factor that enabled the popular success of this theater production was its ability to harmonize the themes or contents with a traditional play to meet the unique trends and tastes of Spanish viewers who were still appreciated earlier Baroque theater, rather than complying with external norms of neoclassicism such as principle of three unities or exclusion of comic figures etc. That is, Spanish viewers of the time thoroughly rejected theater of neoclassicists who attempted to unilaterally enlighten them while regarding the Baroque theater of earlier times as full of superstition and irrationality, illogic and disorder, regardless of their own dramatic taste. In this situation, Huerta's tragedy Raquel, achieved the harmony of neoclassical tragedy and Spanish theatrical tradition. It thus emphasizes the importance of public support and sponsorship in dramatic success. Traditional dramatic elements shown in Raquel can be summarized as honor, poetic justice and love and these elements are major dramatic codes penetrating the entire Baroque theater of Spain.

About 18th century in the late Chosun dynasty, various kinds of 'Min-Wha' had played a significant role and had an important meaning in the lives of the people in that period. Therefore, both in material and in technique, so many diversified 'Min-Wha' were mass produced in that time. Starting from those backgrounds, 'Hyuk-Wha', is considered as one of unique style of expression. Though, 'Hyuk-Wha', in techniques, was originated from 'Bibaekseo' classified as one of the style of expression in Oriental drawing and writing art. 'Hyuk-Wha' shows and expresses visual differentiation from rough 'Bibaekseo', in substance, written by brush made from the skin of a willow tree or the stem of a sort of reeds. 'Hyuk-Wha', in mode, has very dose relation to the process of the development of 'Min-Wha'. Judging from this point of view, 'Hyuk-Wha' has deep relationship to Taosmic character painting of 'Gilsang: an auspicious sign' or Confucian character painting of 'Hyojae: filial piety. Accordingly, 'Hyuk-Wha' has been developed to that character painting designed by another type of creative differentiations. For these reasons, 'Hyuk-Wha' which significantly shapes and contains the meanings of Chinese Character also has been esteemed to have interrelation with Pictography in application of Word mark or Brand logotype in graphic areas. 'Hyuk-Wha' which was prevalent in use of home decorations for the people existed in the past has been ceased to exist nowadays in use of home decorations by appearance of all sort of decoration articles. All these days, 'Hyuk-Wha' which was diversified as a part 'Min-Wha' and developed together with oriental drawing and writing art and character painting is to be necessarily relighted. And 'Hyuk-Wha', which is also vigorously in practical application in Western Europe is desirable to be reconsidered.

'Vision Zero' criticizes an existing traffic safety policy that presupposes a reasonable human beings. It suggests that traffic safety policies should be on the possibility of making mistakes by irrational beings. Under the ethical vision that human life and health cannot be exchanged for any other social benefits, the policy issue should allow to make zero out the death rate and serious injuries of traffic accidents while allowing minor injuries. 'Vision Zero' argues that the government should design an environment in which individual mistakes never lead to fatal accidents. 'Vision Zero', which shows a different perspective from existing policies regarding safety ultimate goal, is spreading from traffic safety to other areas such as health, safety and well-being.

Worldwide Interoperability for Microwave Access (WiMAX) is an efficient technology for 20th century communication system. The technology provides broadband speed without the need for cables and is based on the IEEE 802.16 standard(also called Wireless MAN). Mobile WiMAX is defined as IEEE802.16e which is advanced and efficient technology for mobile telecommunication rather than GSM, CDMA technology. In this work link budget calculation for WiMAX have been done. Cell range have been calculated over digital modulations and they are BPSK, QPSK and QAM. Here different types of models like Cost 231 model have been used for different types of areas like open, rural and urban areas and Erceg-Greenstein model for sub-urban areas. Effect of various parameters like frequency, base station antenna height, transmission power and SNR over cell range have been studied. Analysis have done for both uplink and downlink.
