  • Global warming has affected the distribution of organisms for decades and has displayed rapid ascent recently. Research into the effects on tropical organisms are vital. Padina boryana is a resourceful marine microalgae in the Maldives Sea in the Laccadive region. A 70% ethanol extraction (PBE) of this seaweed was used to investigate its antioxidant potential. Both in vitro and in vivo models were implemented. PBE exhibited protective potential against H2O2 induced apoptosis. ROS levels were suppressed due to PBE. PBE expressed a cytoprotective nature. In vivo experiments involving the zebra fish model conformed its validity. The antioxidant efficacy of PBE was dose dependent. Study outcomes suggest PBE has potential as a novel and valuable marine resource to aid the functional food and cosmeceutical industries.

  • 농촌용수는 자연계의 물순환과 융합한 형태로 반복과 순환의 특징을 갖고 있으며, 지역의 건전한 물순환 형성에 중요한 역할을 담당하고 있다. 또한 식량생산 기반으로서의 역할뿐만 아니라 환경 보전, 전통문화 및 지역사회 등과 밀접한 관련이 있어 사회적 자본으로서의 큰 역할을 하고 있다. 그러나 최근 쌀 소비의 급격한 감소로 논 경작면적이 축소되면서 밭 경작면적이 증가하고 있어 우리나라 농업형태가 논 관개 시스템에서 밭 관개 시스템의 특용작물 재배와 같은 첨단시설의 하우스 농업 형태로 변화하고 있음을 알 수 있다. 농촌용수의 활용은 감소하고 있고 관개 형태의 변화로 용수관리 시스템에 대한 중요성이 대두되고 있고, 관개시스템에서 농촌용수의 효율적인 이용을 위한 수로형태의 변화는 개수로 중심에서 관수로 중심으로 진화하고 있는 상황이다. 농촌용수를 저장, 운용 실태를 보면 노후 된 농업기반시설들로 인하여 저수량 감소가 발생하며, 확보된 용수를 재래식으로 운용함으로 인한 관리 손실발생으로 농촌용수 부족사태를 발생시키고 있으며, 농촌용수 관개를 위한 개수로에서의 용수 손실률은 약 15%에 달하며 이는 약 20억$m^3$으로 추정되고 우리나라 총 수자원의 6%에 해당되는 양이다. 본 연구에서는 관개지구의 급수관리 계획 및 사례 분석을 통해 기존의 모의에 의한 농촌용수 추정 값의 불확실성을 확인하고 실측에 의한 정량화 분석을 통해 관수로 시스템 구축의 타당성 제시 및 효과 분석을 하고자 한다.

  • This study aims to elucidate the origin and yield of life and its characteristics and purpose in Daesoon Thought. Thereby, Taegeuk (the Great Ultimate) and Sangje (the Supreme God) have been deemed the source and ontology of life. The structure of each living creature is explained through reason (理), energy (氣) and spirit (神). In addition, through vital reason and living energy, the purpose of life makes the realization of the benevolent characteristics of life possible through the mind of Sangje. This line of research is unique among currently available research views of life as it perceives the spirit to be an ontological entity with functions and interactive engagement. By way of contrast, prior research suggests that spirit is life itself and includes it in the category of life and death. The Daesoon view of life is unique in that it is somewhat influenced by ontology and developmental theories from Confucianism, yet the concept of divine beings suggests a humanistic Sangje, who presides over the Great Ultimate. The realization of reason in this model is rather thought-provoking. Humans, just like other living things, are born with vital essence and function and interact as a main source to preside over the innate spirits inside themselves. Humans take responsibility for a certain sphere in the Three Realms that make up the world. They are also recognized as a significant feature in the world. Such an idea in Daesoon Thought depicts that 'the enshrinement of spirit into human being (神封於人),' follows Heaven and Earth. This is done to rectify humans in order to meet the needs of the universe and ultimately establish the era of the enshrinement of spirits into human beings. As for humanity, this possibility exists because of the spirits contained within their inner-selves. When cultivating oneself, humans and outer spirits actively interact with each other. This is likely to cause changes in a human's constitution and characteristics. In the end, one can be enshrined with corresponding divine beings according to one's degree of cultivation. Humans are born through the command of Sangje and the accomplishments of their ancestors as well as the energy of the universe. Present day humans encounter the era of human nobility and the era of humankind's divine salvation. Thereby, the purpose of human life is to contribute to the universe. To achieve this goal, the most important thing is to wholly realize that one's nature and reason were endowed by Heaven, which emerged from virtuous conduct in society. This is also akin to the movement of reason in Jeungsanist Thought. Sangsaeng (mutual beneficence) among oneself and others and between human beings and divine beings can be completed through the resolution of grievances for mutual beneficence and the grateful reciprocation of favors for mutual beneficence. If one accomplishes the perfected state of one's own nature and reveals it wholly, then one will be fully able to interact with spirits and reach the state of the human nobility.

  • Purpose: We investigated how intensive care unit (ICU) nurses understand the meaning of death, death anxiety, death concern and respect for life. Methods: From November 2009 through February 2010, a survey was conducted on 230 nurses working at the ICU of 10 general hospitals located in Seoul and Gyeonggi province. Participants were asked to answer a questionnaire consisted of 67 questions under four categories of the meaning of death, death anxiety, death concern and respect for life. Results: Participants scored 4.27 points on their understanding of the meaning of death, 4.43 on death anxiety, 4.12 on death concern and 4.18 on respect for life. Participants' meaning of death was negatively correlated with death anxiety and death concern and positively with respect for life. Participants' positive meaning of death was negatively correlated with death anxiety and death concern and positively with respect for life. Participants' negative meaning of death was negatively correlated with death anxiety and death concern and positively with respect for life. Participants' death anxiety was positively correlated with death concern and negatively with respect for life. Participants' death concern was negatively correlated with respect for life. Conclusion: Compared with nurses who served at ICU for a long time, nurses with less ICU experience scored lower on the meaning of death and respect for life, while they presented high anxiety and concern about death. A training course may help nurses develop their view on the meaning of death, which in turn would enhance their performance in caring dying patients.

  • This study was performed to understand the reproductive ecology of cephalopods, described the microanatomical structure of the male reproductive organs and spermatophore in the common squid, Todarodes pacificus, a major cephalopods in Korea. The common squid was gonochorism and had sexual dimorphism, the color of the reproductive organs reflected on the mantle and the presence of the hectocotylus. Male reproductive organs were composed of testis, primary vas deferens, spermatophoric gland (seminal vesicle), spermatophoric sac (Needham's sac) and secondary vas deferens. The male has specialized reproductive organs such as the spermatophore forming organ, spermatophoric gland. Testis was histologically a seminiferous tubule type. The primary vas deferens was a thin and inverted triangular spring-like form that connected from the rear of the testis to the spermatophoric gland. Inside, it was filled with sperm of basophilic in H-E stain. The spermatophoric gland is an irregular oval connected to the primary vas deferens and spermatophoric sac, and there were a number of tubular glands. The spermatophoric sac is a tubular structure located between spermatophoric gland and secondary vas deferens, and a number of spermatophores have been identified in the lumen. The secondary vas deferens was connected to the posterior of the spermatophoric sac and had a spermatophore inside. The spermatophore was a long, transparent tube about 22 mm long, with a sperm mass inside.

  • The aim of this study was to examine the characteristics of views of life and death and spiritual wellbeing of medical and non-medical university students and to compare their correlation. To this end, 95 medical students from H University and 103 non-medical students from A University were sampled for this research. The research results are as follows: For both medical and non-medical university students, negative meaning of death was found to be most high among sub-factors of views of life and death. Medical and non-medical university students differed in death anxiety and life respect will as medical students showed lower death anxiety and higher life respect will than non-medical students. As a result of analyzing the correlation between view of life and death and the sub-factors of spiritual wellbeing, religious wellbeing showed negative correlation with meaning of death, and both existential and religious wellbeing showed positive correlation with life respect will in medical university students. The results of this study are expected to be helpful in constructing differentiated contents in biomedical ethics education for medical university students who will be exposed to medical deaths.

  • Basic bioactivities (antioxidant, anti-inflammatory, antibacterial, anticancer, antiviral) were investigated from 370 strains of marine bacteria, fungi, and microalgae obtained from various marine environmental regions in Korea, and the activity results were obtained at the collection site, isolation source, and species level was compared. In the case of marine bacteria, strains belonging to the generally useful genera Streptomyces and Bacillus were observed to have particularly strong efficacy and useful resources were mainly isolated from marine sediments. In the case of marine fungi and microalgae, results showing strong species-specific activity were confirmed, and results showing efficacy-specific activity were also obtained. Based on these results, it is a research result that can facilitate priority access as a strategic material for industrial revitalization and the establishment of a strategy to secure resources based on usefulness when conducting research on chemicals that are selectively effective against specific diseases or when conducting resource-based research. In addition, we believe that by using these results as material for sale through the Marine BioBank (MBB), academia and industry can use them to help accelerate the revitalization of the marine bio industry.
