The study was carried out to investigate the influence of demographics and social media use on perceived academic stress of secondary school students in St. Thomas Aquinas College, Akure, Nigeria. This was achieved using five research questions and four null hypotheses. The population of the study consisted of 1,107 students at ISCED level 3, out of which 286 were selected based on the Israel (2003) model for determining sample size. The Ex-Post Facto (EPT) research design of the correlational type was employed to investigate the study while questionnaire was used for data elicitation. Out of the 286 copies distributed, 192 (67% response rate) were retrieved and analyzed using descriptive statistics (frequency, percentage, mean and standard deviation) and inferential statistics (correlation and multiple regression). The findings revealed that there is high frequency of social media use among secondary school students, majorly for meeting new friends and chatting. The perceived academic stress (PAS) of the students was found to be moderate. Of the three demographics considered, only class had significant influence on PAS. Use of social media did not have significantly influence on PAS of the students. When combined, demographics and social media use predicted PAS; and when considered relatively, of the independent variables, only class as an aspect of demographics predicted PAS. Therefore, the authors concluded that PAS of secondary school students is not directly influenced by demographics (except for class) and social media use. Based on the study's conclusion, recommendations were made.

The antifungal activity of isolated lactic acid bacteria (LAB) from a locally fermented cereal, "Kunu", was tested against toxigenic Aspergillus flavus. The liquid refreshment, "Kunu", was prepared under hygienic condition using millet, sorghum, and the combination of the two grains. The antifungal potential of isolated LAB against toxigenic A. flavus was carried out using both in vitro and in vivo antifungal assays. The LAB count from prepared "Kunu" ranged from $2.80{\times}10^4CFU/mL$ to $4.10{\times}10^4CFU/mL$ and Lactobacillus plantarum, Lactobacillus delbrueckii, Lactobacillus fermentum, Pediococcus acidilactici, and Leuconostoc mesenteroides were the isolated bacteria. Inhibitory zones exhibited by LAB against toxigenic A. flavus ranged from 5.0 mm to 20.0 mm. The albino mice infected with toxigenic A. flavus showed sluggishness, decrease in body weight, distortion of hair, and presence of blood in their stool, while those treated with LAB after infection were recovered and active like those in control groups. Except for the white blood cell that was increased in the infected mice as $6.73mm^3$, the packed cell volume, hemoglobin, and red blood cell in infected animals were significantly reduced (P<0.05) to 29.28%, 10.06%, and 4.28%, respectively, when compared to the treated mice with LAB and control groups. The antifungal activity of LAB against toxigenic A. flavus can be attributed to the antimicrobial metabolites. These metabolites can be extracted and used as biopreservatives in food products to substitute the use of chemical preservatives that is not appealing to consumers due to several side effects.

최근 가족의 중요성이 강조되고 있다. 결혼으로 인한 새로운 부부의 탄생 이외에 처가와 시가 등 새로운 가족이 형성되어 새로운 가족과 갈등을 빚기도 하고 화목을 이루기도 한다. 이러한 연구들은 주로 사회학적인 측면에서만 연구되고 있고 자연과학적인 측면의 하나인 가족관계에 대한 수학적인 모델링이 없어 근본적인 가족 사이의 거동 현상을 밝혀내지 못하고 있다. 이에 본 논문에서는 사회에 대한 비선형 연구의 하나로 가족 구성원 간 특별히 시부모와 며느리의 관계나 처부모와 사위와의 관계를 로미오와 줄리엣의 사랑 모델을 변형하여 보다 확장된 가족 관계 모델을 제안하고 이 모델을 통하여 시계열과 위상공간을 통하여 비선형 거동의 대표적인 특성인 카오스 거동이 있음을 보인다..

A preliminary investigation to establish the status of contamination of trace metals in the Western coast of Ghana was conducted prior to the commercial production of crude oil in the area. The study revealed the presence of heavy metals such as Pb (4.00-79.64 mg/kg), As (8.81-236 mg/kg), Cu (12.86-108.06 mg/kg), V (28.07-953.32 mg/kg), Zn (7.08-264.25 mg/kg), Cr (101.69-1366.62 mg/kg), Ni (42.41-451.43 mg/kg), Mn (16.77-1890.45mg/kg), Br (7.66-142.78 mg/kg), Ti (542.03-19960 mg/kg) and Fe (7472.88-97120 mg/kg) at six sites sampled along the coast. With the exception of Ti and Fe which showed no variation in metal concentration, the rest of the metals varied significantly among the sampled locations. Potential ecological risk of metals particularly of Co, As and Br which exhibited extreme enrichment of the sediments indicates considerable metal pollution in the studied areas. The degree of contamination is of particular concern especially to benthic biota that inhabit this environment for survival.

본 연구는 그림에 나타난 정서를 판단할 때에 형태 정보와 색채 정보가 미치는 영향을 알아보고자 하였다. 예비연구에서 흑백 그림자극의 정서적 반응을 평가하였고, 본 실험에서 색채가 첨가된 그림의 정서적 반응을 평가했다. 두 개의 실험에 각기 다른 50명, 56명의 피험자들이 참여하였고, 평가-능력-활동성 차원에서 구분이 되는 평정 단어로 기쁨, 우울, 분노 반응을 선택하도록 했다. 그 결과, 흑백 그림에서 형태의 표면과 리듬에 따라 특정 정서를 높은 비율로 경험했다. 그리고 형태가 제시하는 정서반응과 다른 정서반응을 일으키는 색채가 가미되었을 때 특정 정서의 반응 비율이 현저하게 낮아지거나 혹은 색채 정보에 따른 정서를 경험한다는 것을 발견했다. 본 연구는 기존의 연구와 달리 색채와 형태를 결합하여 두 요소를 경합시키고 그 결과를 논의하였다는 점과 자극의 제시와 반응의 처리에 있어서 보다 더 통제된 조건 하에서 실험했다는 점에서 의의를 가진다.

Shakespeare's plays deploy an interesting array of food signs in a way to illuminate the historical process of what Stephen Mennell has described as "the civilizing of appetite"-a process in which the changes of food choices and eating habits took place in response to the changes in people's way of life and personality structure over the long-term modern period since the middle ages. Shakespeare's plays suggest that the civilizing of appetite in early modern England was heavily affected by the forces of social mobility as well as the nascent market economy. The Capulets' costly preparation of Juliet's wedding banquet is a showcase of conspicuous consumption which was a structural necessity for the ruling class in Shakespeare's time. Some fifteen years later, the same kinds of foodstuffs are included in a shepherd's shopping list for the sheepshearing festival in Winter's Tale. This is a significant coincidence to prove that food was an important source of emulation and contest among different social classes; and that the rich diet of the upper class gave impetus to social mobility. The Elizabethan subjects, especially among the elite noblemen, were interpellated by the ideology of food that equated the quality of food and the eater's social identity. Faced with bankruptcy as a consequence of his extravagant consumption habit, Bassanio in The Merchant of Venice testifies to the gripping ideology of food onto early modern people, while Poor Tom in King Lear presents a comic parody of the rich people's conspicuous waste. Also in Coriolanus and The Merry Wives of Winsor, Shakespeare uses food as a metaphor for class-motivated social struggles.

The study investigated the Integration of Information and Communication Technology (ICT) to the Library and Information Science Curriculum: The Practicum in Library Schools in Rivers State. Descriptive survey design was used with a population 374 comprising 21 LIS educators and 353 Four Hundred Level Library and Information Science Students from University of Port Harcourt, Rivers State University, Port Harcourt, and Ignatius Ajuru University of Education Port Harcourt. Census sampling technique was used to select the LIS educators and purposive sampling technique was used to the select the Four Hundred Level LIS students. Questionnaire and checklist were used for data collection. 90% and 97% responses were found valid for analysis for LIS Educators and LIS students respectively. The study was analyzed using mean rating, standard deviation and simple percentage. The study revealed that ICT courses were integrated into LIS curriculum in Library schools in Rivers State but LIS educators lacked the ICT skills to teach ICT practicum consequently, the students were not properly taught ICT practicum. However, students had positive perception of ICT practicum. Notwithstanding, lack of ICT skills, poor policy implementation, lack of state-of-the-art infrastructure and nonchalant attitudes of staff towards the adoption of ICT constituted the challenges faced in the implementation of ICT practicum. The study therefore, recommended that the management of library schools in Rivers State should implement ICT practicum by hiring competent staff maybe from computers science department to teach the practicum for the interim. Subsequently, recruitment of librarians should include strictly ICT compliant.

현대는 여성이 소비를 리드하는 시대라고 할 수 있을 만큼 소비시장에서 여성의 파워가 신장되고 있고, 기업들은 기존시장의 과다경쟁과 포화상태에서 벗어나기 위해 여성이라는 소비시장으로 눈을 돌리고 있는 상황이다. 더욱이 소비자 욕구가 다양화되어가는 추세에 부응하기 위해 기업들은 새로운 시장 전략으로써 여성시각에서 상품과 서비스 개발을 적극적으로 전개해야 할 필요성이 커지고 있다. 앞으로 소비시장의 주역으로 주목받고 있는 여성들만의 독특한 문화에 대한 세밀한 관찰과 이해, 조사연구의 필요성이 커지며 지속적으로 수행하는 기업만이 시장선점에 앞장설 수 있을 것이다. 자동차업계도 예외는 아니어서 볼보, 포드자동차를 중심으로 여성전용 자동차 디자인 및 편의장치 개발에 심혈을 기울이고 있으며, 1998년 대우자동차의 '라노스, 줄리엣'을 시작으로 국내에서도 여성자동차 유저를 위한 디자인이 적용되고 있다. 그러나 국내에서는 구체적이고 연구결과가 제시되고 있지는 않은 실정이다. 본 연구는 여성자동차 유저의 중요성을 제기하고, 실내편의장치를 중심으로 여성자동차 유저의 특성 및 니즈를 조사, 분석하여 그 결과를 적용한 디자인을 제안하여 여성구매자들의 중요성을 인식시키는데 목적이 있다.

A movie which brought its material from a historical character or incidents in the past was produced by a story suggestion through a historical fact. It is because Shakespeare created a story based on a mythical element related with his life in the plot which was written from the script of the play and was on the show in the cinemas of London. It is an obvious fact that the historical drama of this movie was intentionally modified and the fictional story was added to episodes in order to create a dramatic effect. However, reflecting historical backgrounds and cultural aspects accurately through a historical study would also be an important factor. Therefore, the backgrounds and aspects presented in this movie are a kind of storytelling which was reconstructed as if a historian added his opinion to historical facts like a discourse. A historical background in was a story about Shakespeare who worked at the theater in London as a writer in 1593 the period of England Reneissance. The movie included the working and playwriting of Shakespeare who is a main character. This indicated not only the environment of the theater and literature during the reign of Queen Elizabeth I but also historical aspect in the early modern industrial society in England. This movie, that is, described that time as a recreation such as a cultural acceptance and an achievement of an initial capitalism in Renaissance in the life of characters. In particular, the factor of theaters flourishing during the Renaissance was because a newly emerging class, bourgeoisie, who held the capital emerging from a policy for middle class led to a box office hit through founding theaters and drama company and selling tickets and performing plays by themselves. Like this, the movie depicted the time led by plays to a industrialization. Moreover, Social aspects in the late 1500s were revealed in this movie through a depiction of the cinemas and the city of London. The depiction of the city of London reflected a social situation of an initial capitalism rapidly developed in trade and commerce. The social aspects such as conflicts between social classes based on getting richer and poorer, mammonism, a corrupted love between the male and the female, a immortality with growing brothels, religious and political conflicts with the foundation of the church in England were closely linked with characters' daily routine at that time in London and were reflected in this work overall. The reason why we highlight characters' job and custom like this in the movie is that these are ideationally inherent in a critical mind from people at that moment. The historical background and reproduction of the image depicted in the movie were focused on characters' daily routine and indicated the problem mentally and independently exposed in the form of initial capitalism.

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.
