Recent years have witnessed renewed interest in Africa and public diplomacy has emerged as the vital tool being used to cultivate these relations. China has been leading in pursuing stronger economic partnership with Africa while middle powers such as Korea are also intensifying engagement with the continent. While previous studies have analyzed the implications of China's activities in Africa on advanced powers, none has examined them from the paradigm of middle powers. This study fills this gap by assessing China's activities in Africa, their economic engagement and implications for Korea's interest in Africa. The analysis is qualitative based on secondary data from various sources and literature. The study shows that China's public diplomacy strategy involves a high degree of innovation and has evolved to encompass new tools and audiences. China has institutionalized a cooperative model that permeates many aspects of governance institutions in Africa, enabling it to strengthen their relations. This could also be helping China to adjust faster leadership transitions in Africa. Whereas the US is still the most influential country in Africa, China is influential in economic policies and has outstripped the US in infrastructure diplomacy. This could be because African policy makers align more with China's economic model than the US' mainstream economics. Chinese aid to Africa has been diversified to social sectors that are more responsive to the needs of Africa. Trade and investment relations between China and Africa have deepened, but so does trade imbalance since 2010. China mainly imports natural resources and raw materials from Africa. But this product portfolio is not different from Korea and the US. China's energetic insertion in Africa using various strategies has significant implications for countries with ambitions in Africa. Korea can achieve its ambitions in Africa by focusing resources in areas it can leverage its core strengths-such as education and vocational training, environmental policy and development cooperation.

Background: Workers are exposed to several risks in academic laboratories due to the presence of potentially hazardous substances. The main objective of this study was to assess the prevalence of accident occurrence and associated risk factors among laboratory workers at the scientific laboratories of the public university in Lebanon and the impact of safety measures training and availability. Methods: In this observational study, a survey was conducted for one year in scientific laboratories at faculties of the public university. Results: Among the participants (N = 220), 45.0% have had accidents; the main cause was exposure to chemicals (73.7%) and more specifically by inhalation (45.4%). Females (85.9%) were more exposed to accidents than males. Laboratory workers with a master's degree, a full-time schedule, and more than ten years of experience were significantly more exposed to accidents (p < 0.05). A significant association was found between accident occurrence and training on management of hazardous products (p = 0.044), risks related to workplace (p = 0.030), eyewash and emergency shower (p < 0.001), first aid (p = 0.012), and facial protection availability (p = 0.019). In spite of the lack of safety culture and efficient training on laboratory safety, participants have shown a very good perception regarding safety measures to be applied in case of work accidents. Conclusion: Based on our findings, the prevalence of accident occurrence is elevated among lab workers at the public university. The impact of regular training on laboratory safety preventive measures is of great importance to ensure the efficiency of occupational health and safety in scientific laboratories.

Red macroalga Pyropia yezoensis is a high valuable cultivated marine crop. Its acclimation to cold stress is especially important for long cultivation period across winter in coasts of warm temperate zone in East Asia. In this study, the response of P. yezoensis thalli to low temperature was analyzed on physiology and transcriptome level, to explore its acclimation mechanism to cold stress. The results showed that the practical photosynthesis activity (indicated by Φ_PSII and qP) was depressed and pigment allophycocyanin content was decreased during the cold stress of 48 h. However, the F_v/F_m and non-photochemical quenching increased significantly after 24 h, and the average growth rate of thalli also rebounded from 24 to 48 h, indicating a certain extent of acclimation to cold stress. On transcriptionally, the low temperature promoted the expression of differentially expressed genes (DEGs) related to carbohydrate metabolism and energy metabolism, while genes related to photosynthetic system were depressed. The increased expression of DEGs involved in ribosomal biogenesis and lipid metabolism which could accelerate protein synthesis and enhance the degree of fatty acid unsaturation, might help P. yezoensis thallus cells to cope with cold stress. Further co-expression network analysis revealed differential expression trends along with stress time, and corresponding hub genes play important roles in the systemic acquired acclimation to cold stress. This study provides basic mechanisms of P. yezoensis acclimation to cold temperature and may aid in exploration of functional genes for genetic breeding of economic macroalgae.

본 연구에서는 서울 소재 한 전문대학 학생들을 대상으로 하여 최소한의 인구통계학적 변수와 1학년 1학기 성적을 활용하여 학생들의 최종 학적 상태를 예측하고자 하였다. XGBoost와 LightGBM 모델을 사용한 결과, 이러한 변수들이 학생들의 제적 여부 예측에 유의미한 것을 발견하였다. 이는 학업 시작 초기의 성적이 학업 중단의 중요한 지표가 될 수 있음을 시사한다. 또한, 전문대학의 학제가 최종 학적에 영향을 미칠 가능성을 확인하였으며, 이는 학업 기간이 학생들의 학업 중단 결정에 중요한 요소임을 나타낸다. 전문대학에서 조기 학업 중단 의도를 파악하는 데 있어 심리적, 사회적, 경제적 요인에 의존하지 않고 학업 성취도만을 기준으로 모델링을 시도하였다. 이는 향후 학업 중단에 대한 조기 경보 시스템 구축에 도움이 될 것으로 기대된다.

Analyzing the proportion of domains of safety education in five textbooks, the Meaning of Safety and Basic Principles occupied the highest portion (29.5％), and that was followed by the Home Safety (24.0％), the Safety in School (17.1％), and the Play and Leisure Safety (14.0％). The Coping with Accidents and First Aid, the Safety from Fire and Explosion, and the Traffic Safety occupied relatively low portion, 6.9％, 5.7％, and 2.8％ each. 3. As a result of analysis of the proportion of the safety education domain in each subject, the Meaning of Safety and Basic Principles occupied the highest portion (23.6％) in Moral Education, the Home Safety (12.7％) in Practical Subject, and the Play and Leisure Safety (10.9％) in Physical Education. 4. Most of the participants in this survey experienced the Home Accidents (71.1％). And also, they experienced the Play and Leisure Accidents (57.9％), the Accidents in School (49.7％), the Traffic Accidents (45.3％), and the Fire and Explosion Accidents (24.7％) in order. 5. In the average proportion of the needs of participants for safety education in each domain, the Coping with Accidents and First Aid has the highest point (4.05). And, that was followed by the Home safety (3.79), the Safety from Fire and Explosion (3.73), the Meaning of Safety and Basic Principles (3.65), the Play and Leisure Safety (3.50), the Safety in School (3.37), and the Traffic Safety (3.35). The average proportion of the needs for safety education of total domains was 3.66. 6. In the needs for safety education regarding the feature of participants, it showed higher scores in female students than male ones (p〈0.001), in lower grader than higher grader (p〈0.05), and in the students born to wealth than those born poor (p〈0.05). Also, the children who recognize the necessity of safety education showed higher scores of the needs for safety education (p〈0.001). And it also showed the same results of high score to the children whose parents did the safety education (p〈0.00l) and to the children and their parents who have the higher degree of practicing safety (p〈0.001), and these differences were statistically significant. 7. In the extent of preference for methods of safety education, it showed high score to the Field Learning, followed by the Audio- Visual Education, the Discussion, and the Instruction of teacher. In the extent of preference for subjects regarding the contents of safety education by each domain, it showed high score to the subject of Safety for 4 domains - the Meaning of Safety and Basic Principles, the Traffic Safety, the Safety from Fire and Explosion, and the Coping with Accidents and First Aid. And also, they preferred Moral Education for 2 domains - the Home safety and the Safety in School, and Physical Education for a domain of the Play and Leisure Safety. 8. While 27 of 36 detail items was contained the contents of safety education, the proportion of needs of participants for safety education showed more than average 3.00 score in 34 of 36 detail items.

Methods : The period of data collection was from May 1 to 15, 2009, 300 freshman, sophomore and junior students who understood the purpose of the research and agreed to participate in the questionnaire were randomly sampled, structured questionnaire was distributed to them and their responses were collected. Instruments used for this study included those used by Kim and Lee and revised and complemented by this researcher to measure the knowledge of AIDS and those by Yun and Lee revised and complemented by the researcher to measure the attitude of AIDS. For data analysis, it measured technical statistics, t-test, ANOVA, and Pearson's correlation coefficient using SPSS/PC 12.0. Results : The results of this study are summarized as follows. 1. The whole knowledge of AIDS the subjects had scored 58.9 and their average attitude scored $3.78(1{\pm}25)$. 2. In the degree of knowledge of AIDS depending on general characteristics and health-related characteristics of the subjects, it was found that the students at the department of emergency medical showed higher knowledge(t=3.638, p=.001) and positive attitude of AIDS(t=3.330, p=.001) compared to students at other majors. 3. In the degree of knowledge of AIDS depending on AIDS-related education, subjects who had experienced AIDS education(t=1.973, p=.050), those with the experience of theory education(F=4.057, p=.008), those who felt the necessity of AIDS education(t=4.588, p=.000), and those who were willing to take part in AIDS education(t=2.898, p=.004) showed higher know1edge of AIDS. In the attitude of AIDS, subjects with theory-oriented AIDS education(F=3.012, p=.032), those who felt the necessity of AIDS education(t=2.445, p=.015), and those who were willing to take part in AIDS education(t=2.379, p=.018) showed positive attitude of AIDS education. 4. As the knowledge of AIDS the subjects was higher(r=.329, p=.000), they showed more positive attitude of AIDS and it meant that there was positive correlations. Conclusion : Consequently, systematic, concrete and continuous education of AIDS suitable to the requirements of college students is needed to induce changes of their knowledge and attitude of AIDS and for this, AIDS education program which can be used properly by the developmental stages of college students who belong to late adolescence should be developed in the field of school and if possible, curriculum of sex education including AIDS education should be established in all departments of college.

In this paper the good Samaritan civil liability is argued. In many cases some damage could be caused by an emergency medical service. In such situations the degree of duty of care taken by the service provider would be alleviated depending upon the degree of emergency. Then the service provided by anyone not carrying any duty to do so could be generally ruled by the 'Korean Civil Act' Article 735. This article is related to the management of affairs in urgency. The application of this article means the mitigation of civil liability of the service provider. If the service provider not carrying any duty to provide it "has managed the affairs" of the service "in order to protect the" victim "against an imminent danger to the latter's life", the provider "shall not be liable for any damages caused thereby, unless he acted intentionally or with gross negligence". Korea has another rule applied in such a situation, that is the Korean 'Emergency Medical Service Act' Article 5-2. This article is established for the exemption from responsibility for well-intentioned emergency medical service. It could be referred to as the Good Samaritan law. It provides: "In cases where no intention or gross negligence is committed on the property damage and death or injury caused by giving any emergency medical service or first-aid treatment falling under any of the following subparagraphs to an emergency patient whose life is in jeopardy, the relevant actor shall not take the civil liability ${\cdots}$" In this paper the two articles is compared in the viewpoints of the requirements for and effects of the application of them respectively. The 'Korean Civil Act' Article 735 is relatively general rule against the the Korean 'Emergency Medical Service Act' Article 5-2 in the same circumstance. Therefore the former could be resorted to only if any situation could not satisfy the requisites for the application of the latter. In this paper it has suggested that the former article be more specific for the accuracy of making decision to apply it; and that the latter be revise in some requirements including the victim, the service provider, and the service.

최근 우리나라에서 장애인의 수가 증가하고 있으며, 특히 전체 장애인의 수에서 장애아동이 차지하는 비율이 약 5%를 넘는 것으로 나타났다. 이에 따라 장애아동에 대한 관심이 증가하면서 급여정책에 대한 이용자 만족도를 중심으로 한 연구가 진행되고 있지만, 현금과 바우처 이용자 만족도를 비교 및 영향 요인에 대한 연구는 부족하였다. 이러한 문제인식과 연구의 필요성을 바탕으로 장애아동정책의 급여형태에 다른 이용자 만족도를 연구함으로써, 궁극적으로 급여정책에 대한 함의를 이끌어내는 것을 그 목적으로 두고 있다. 인구사회학적특성이 이용자 만족도에 미치는 영향에 대하여 분석한 결과, 현금급여에는 장애등급이 이용자 만족도에 영향을 미치는 것으로 나타났다. 바우처에는 부모성별, 장애등급, 평균소득이 이용자 만족도에 영향을 미치는 것으로 나타났다. 연구의 함의는 다음과 같이 제시하였다. 첫째, 장애아동의 인구사회학적특성을 고려하여 맞춤형 서비스를 제공해야 한다. 둘째, 현금급여의 지급액 및 범위를 확대해야 한다. 셋째, 현금급여, 바우처의 서비스량을 확대 지급해야 한다. 넷째, 저소득층(기초수급자, 차상위계층)의 경제적 부담에 도움이 되도록 바우처를 제공해야 한다.
