Smoking has become one of the public health harzard affecting the world. In the UK, smoking is responsible for around one in five deaths. The illnesses caused by smoking extend beyond the well-reported links with cancer, heart disease and respiratory illnesses. Hence the research to determine the awareness of the predisposing factor to smoking among adults in sokoto metropolis. A cross-sectional form of descriptive survey research design was used for this study. This is because descriptive studies are used when the characteristics of a population are either unknown or partially known (Hennekens & Buring, 2007), and it was used by Ganley and Rosario (2013) in a related research this justified the use of similar design in a study of similar nature.Two hundred and seventy returned questionnaire was collected, analyzed using descriptive statistic of frequency count, normative percentage and grand mean; as well as inferential statistics of chi-square (${\chi}^2$). The level of significant was fixed at 0.05. Appropriate degrees of freedom were worked out. There was statistical significant influence or relationship with marital status on the predisposing factors of smoking chi-square of 19716.516 greater than the critical value 43.77297at df 30 p<0.05. There were statistical significance chi-square =27468.348 which is greater than the critical value 43.77297 at df= 30. These show that there is a relationship on gender awareness of predisposing factors to smoking rejecting the null hypotheses. The respondents across different lever/year higher institution shows that the awareness of predisposing factors of smoking there were a statistical significance difference chi-square =7168.429 (df=88) greater than critical value 102.342 rejecting the null hypotheses. There is consistent evidence that links exposure to depictions of smoking in movies and initiation of smoking in young people. Over the years television shows and films have effectively built up associations between smoking and glamour, sex and risk-taking. Social learning theory describes how we learn by example from others. We are strongly influenced by our parents, and other people we look up to, such as peers, actors and pop stars. This can lead us to emulate their behaviour and try smoking.

Hosan Park Moon Ho lived in the truly eventful era with keen competition of western powers, invasion of Japan, Confucianism based Movement against Western Power, Volunteer Army Movement against Japanese and etc. Therefore, his learning and idea could not help being related with such difficult environment of his country. Especially, his idea is directly related with such historical environment of his era in terms of his claims as follow: He thought that Christianity destroyed Korean traditional idea and good customs; he claimed that the nation should subdue the betrayers who were at the Japanese side and be revenged on the murder of the empress Myeongseong; and he advocated his own theory for civilization that the nation should be strictly against the imperial invasion of western powers but work for GaeMulSeongMu(開物成務: Achieving Everything through Enlightenment on Meaning of Everything) and HwaMin SeongSok(化民成俗: Forming Beautiful Customs by Educating the People). The problem that should be urgently solved that time was, first of all, to repel the invasion of Japan and western powers and to realize Confucianism based political ideal by scheming political and social stability and saving the people's livelihood from distress through such repelling.

Park Se-dang who has the pen name of Seogye is a man in the 17th century. Then, Joseon Dynasty is try to restore the state which became impoverished by two wars. When Sung Confucianism of Chu-tz was dogmatized, Seogye analyzed independently the scriptures and was regarded as a traitor against Sung Confucianism. Therefore, this paper discussed the understanding of Seogye's works and its social reflection through the research data about Seogye. Although Seogye has blue blood in his veins, he belonged to a non-mainstream group in the faction of Seo-in and had a liberal inclination. That he has shuned in the school of Sung Confucianism owed to Sabyeunrok of his work, and its main reason is his criticism against Song Si-yeul. He argued the two principles different from Chu-tz's three principles. Also, he not accepted the Chu-tz's theory and was similar to the Wang Yangming school in the issue of gaining knowledge by the study of things Now to conclude, Seogye outstretched the liberal inclination in Sung Confucianism apart from the interpretation of scriptures. He was not indulged in Sung Confucianism of Chu-tz that was gradually ossifying at that time and took his own line. And he devoted himself to the study of practical learning and the education for younger scholars, and had acted as mediator between the Sung Confucianism of Chu-tz and the Practical Science that was in full bloom in the period of King Young-jo and King Jeong-jo.

Chemistry is the subject which includes properties, change, and composition of matter. Chemistry has the system which explains observable properties and change with microscopic level, it explains them using scientific theory and laws. In the national-level curriculum, the properties and changes of matter are continuously dealt with from elementary school to high school, and the curriculum are organized so that students could strengthen their understanding about matter. In other words, understanding of the properties and changes of matter is the base to explain everyday life with the view of chemistry, and these two are classified as domains of chemistry in the 2015 revised science curriculum. In this study, we confirmed students' understanding about properties of matter and change of matter, through the analysis about results of the National Assessment of Educational Achievement (NAEA). For that purpose, this study analyzed the 12 items about properties of matter, and 19 items about change of matter, which were used in the NAEA from 2015 to 2019. According to the results of classifying and analyzing questions according to the core concept, the understanding about the two domains significantly changed between the proficient achievement-level students and basic achievement-level students. Depending on the achievement-level, there was a difference in explaining the phenomenon by using the perspective of particles, and by associating scientific concepts and models, or there was a difference in understanding the inquiry related to these two domains. Based on this analysis, this study discussed some implications to be improved on teaching-learning for 'properties of matter', and 'change of matter'.

Recently, with the introduction of drones, a core technology of the 4th industrial revolution, various convergence education using drones is being conducted in school education sites. In particular, drone theory and practice education is being conducted in connection with free semester classes and career exploration. The drone convergence education program has higher learner satisfaction than simple demonstration and practice education, and the learning effect is high due to direct practical experience. However, since practical education is being conducted for a large number of learners, it is impossible to restrict and control the flight of a large number of drones in a limited place. In this paper, we propose a monitoring system that allows the instructor to monitor multiple drones in real time and learners to recognize collisions between drones in advance when multiple drones are operated, focusing on education operated in schools. The communication module used in the experiment was equipped with GPS in Murata LoRa, and the server and client were configured to enable monitoring based on the location data received in real time. The performance of the proposed system was evaluated in an open space, and it was confirmed that the communication signal was good up to a distance of about 120m. In other words, it was confirmed that 25 educational drones can be controlled within a range of 240m and the instructor can monitor them.

The advantage of piezocone penetration test is a guarantee of continuous data, which is a source of reliable interpretation of target soil layer. Many researches have been carried out f3r several decades and several classification charts have been developed to classify in-situ soil from the cone penetration test result. Since most present classification charts or methods were developed based on the data which were compiled over the world except Korea, they should be verified to be feasible for Korean soil. Furthermore, sometimes their charts provide different soil classification results according to the different input parameters. However, unfortunately, revision of those charts is quite difficult or almost impossible. In this research a new soil classification model is proposed by using fuzzy C-mean clustering and neuro-fuzzy theory based on the 5371 CPT results and soil logging results compiled from 17 local sites around Korea. Proposed neuro-fuzzy soil classification model was verified by comparing the classification results f3r new data, which were not used during learning process of neuro-fuzzy model, with real soil log. Efficiency of proposed neuro-fuzzy model was compared with other soft computing classification models and Robertson method for new data.

To study the evaluation standard and control limit of mortar filling layer void length, in this paper, the train sub-model was developed by MATLAB and the track-bridge sub-model considering the mortar filling layer void was established by ANSYS. The two sub-models were assembled into a train-track-bridge coupling dynamic model through the wheel-rail contact relationship, and the validity was corroborated by the coupling dynamic model with the literature model. Considering the randomness of fastening stiffness, mortar elastic modulus, length of mortar filling layer void, and pier settlement, the test points were designed by the Box-Behnken method based on Design-Expert software. The coupled dynamic model was calculated, and the support vector regression (SVR) nonlinear mapping model of the wheel-rail system was established. The learning, prediction, and verification were carried out. Finally, the reliable probability of the amplification coefficient distribution of the response index of the train and structure in different ranges was obtained based on the SVR nonlinear mapping model and Latin hypercube sampling method. The limit of the length of the mortar filling layer void was, thus, obtained. The results show that the SVR nonlinear mapping model developed in this paper has a high fitting accuracy of 0.993, and the computational efficiency is significantly improved by 99.86%. It can be used to calculate the dynamic response of the wheel-rail system. The length of the mortar filling layer void significantly affects the wheel-rail vertical force, wheel weight load reduction ratio, rail vertical displacement, and track plate vertical displacement. The dynamic response of the track structure has a more significant effect on the limit value of the length of the mortar filling layer void than the dynamic response of the vehicle, and the rail vertical displacement is the most obvious. At 250 km/h - 350 km/h train running speed, the limit values of grade I, II, and III of the lengths of the mortar filling layer void are 3.932 m, 4.337 m, and 4.766 m, respectively. The results can provide some reference for the long-term service performance reliability of the ballastless track-bridge system of HRS.
