  • Since 1990 in South Korea, the considerable concern for the safety of construction sights has been increased due to serious accidents. There have been numerous big improvements in preventing the accidents by strengthening legal enforcement and by continuing to emphasize the safety management. Further, the safety standards and criteria for temporary constructional work have been enacted and established in order to maintain safe work environments in temporary construction and structure settings. However, the death rate from fall accidents is still high in the temporary constructional and structural settings in comparison to other work places in construction. According to the analysis of accidents in the field of construction between 2000 and 2007, the death rate from fall accidents in the temporary constructional settings was highest. In addition, there have been more fall accidents in the work setting by small or medium construction enterprises rather than large enterprises due to the relative lack of the safety management. Thus, in this study, the analysis of the causes of fall accidents in the temporary constructional and structural settings between 2000 and 2007 was conducted. Moreover, a survey study was carried out in order to investigate further causes based on the analysis. Finally, this study was also conducted in order to provide basic information and knowledge about the prevention of future accidents.

  • This study sought to find a nursing intervention tool for enhancing elderly women's lives by investigating the causes and the meaning of their grief. Method: This research was derived from a phenomenological tool such as qualitative research design. The data collection took place from December of 2000 until April of 2001 Through systematic interviews and participatory observations of five elderly women attending C welfare center located in downtown Seoul the data was collected. Each interview lasted an hour and a half and was arranged five times. The analysis of this research was conducted using the Giorgi method. Results: \circled1 There was obvious physical and physiological decline caused by aging old; as well as there being spouse health problems, additional physical suffering, signs of senility, and insomnia, \circled2 Further grief was imposed by unpleasant memories of the spouse; infidelity, incapability, and even disregard of her own well-being, \circled3 Then there was pity for children; unfaithful children, uncertain futures of the children, and early death of a child, \circled4 Also, regrettable fate, painful daily acttrities, unreliable factors, bad circumstances, and feelings emptiness were reported, \circled5 Finally, anxiety for the future; ac sense of despair, loneliness, economic hardship, and the fear of imminent death increased grief levels. Conclusion: A variety of programs and social meetings for the elderly to overcome their physiological or psychological crisis should be substantially developed and supported by the government. In order to implement the social welfare for the elderly women, special consideration whether on the governmental level or the personal level, should be devoted to the elderly who live without any financial support or social concern.

  • Neural cell survival is an essential concern in the aging brain and many diseases of the central nervous system. Neural transplantation of the stem cells are already applied to clinical trials for many degenerative neurological diseases, including Huntington's disease, Parkinson's disease, and strokes. A critical problem of the neural transplantation is how to reduce their apoptosis and improve cell survival. Neurotrophic factors generally contribute as extrinsic cues to promote cell survival of specific neurons in the developing mammalian brains, but the survival factor for neural stem cell is poorly defined. To understand the mechanism controlling stem cell death and improve cell survival of the transplanted stem cells, we investigated the effect of plausible neurotrophic factors on stem cell survival. The neural stem cell, HiB5, when treated with PDGF prior to transplantation, survived better than cells without PDGF. The resulting survival rate was two fold for four weeks and up to three fold for twelve weeks. When transplanted into dorsal hippocampus, they migrated along hippocampal alveus and integrated into pyramidal cell layers and dentate granule cell layers in an inside out sequence, which is perhaps the endogenous pathway that is similar to that in embryonic neurogenesis. Promotion of the long term-survival and differentiation of the transplanted neural precursors by PDGF may facilitate regeneration in the aging adult brain and probably in the injury sites of the brain.

  • A failure of a cell to self destruct has long been associated with cancer progression and development. The fact that tumour cells may not instigate cell arrest or activate cell death mechanisms upon cancer drug delivery is a major concern. Autophagy is a mechanism whereby cell material can be engulfed and digested while apoptosis is a self-killing mechanism, both capable of hindering multiplication after cell injury. In particular situations, autophagy and apoptosis seem to co-exist simultaneously or interdependently with the aid of mutual proteins. This review covers roles of microRNAs and chemopreventive agents and makes an attempt at outlining possible partnerships in maximizing cancer cell death with minimal normal cell damage.

  • Chloral hydrate is the oldest and most common sedative drug used in moderate sedation for pediatric dental patients. Hence, the purpose of this article is to review the safety and possible adverse events of this drug when used for pediatric dental treatment. A bibliographic search in PubMed, MEDLINE, Cochrane Library and KMbase, KISS, DBpia, KoreaMed, and RISS databases was performed. Using the keywords "dental sedation," "chloral hydrate," and "children or adolescent," 512 scientific articles were found. Subsequently, 183 studies were individually assessed for their suitability for inclusion in this literature review. Altogether, 24 studies were selected. They included 12 cases of death before, during, or after chloral hydrate sedation for dental treatment, majorly due to dosing error and use of multiple sedatives. Additionally, intraoperative adverse events were mostly respiratory problems such as hypoxia and apnea, but most events were temporary. After treatment, prolonged sedation, including excessive sleep and less activity were the most common postoperative adverse events, and even death cases were reported. Despite the wide acceptance of chloral hydrate as a sedative-hypnotic agent, the risk of adverse events and adequate dose should be of great concern when using it for pediatric dental sedation.

The Characteristics of Epidemiology Examined through Translated Medical Books in the 16th~17th Century in the Chosun Dynasty (16 ~ 17세기 조선의 벽역의서(闢疫醫書)를 통해 살펴본 온역학(瘟疫學)의 특징)

  • Because the size of population was directly related to the power of the nation in the Chosun Dynasty, various efforts were exerted to maintain the size stable and the keys to the efforts were a high birth rate and a low death rate. However, in addition to wars, epidemic diseases had an enormous effect on the death rate. Particularly during the mid Chosun Dynasty, epidemic diseases were more prevalent than ever due to the abnormal climate called the little ice age. To cope with them, the government executed several medical relief policies and published medical books. In Chinese epidemiology, infectious diseases mean sicknesses caused by hot weather, but in Korean epidemiology, they indicate large-scale infectious sicknesses caused by both hot and cold weather. Therefore, as treatment methods for diseases from the cold were not applicable to the pathology of epidemic diseases, China developed separate epidemiology. In Korea, however, the main concern was how to prevent epidemic diseases, whether from hot or cold weather, that drove many lives into death. The characteristics of Korean epidemiology are as follows. First, whenever epidemic diseases were prevalent, in order to cope with them, translated medical books were promptly published including Ganibyeokonbang, Bunmunonyeokihaebang, Sinchanbyeokonbang, Byeokyeoksinbang and Byeokonsinbang. Second, those books were annotated in Korean so that people could read easily and accurately. Third, as an extension of the Hyangyak movement from the late Koryo Dynasty, Danbang was used a lot to treat and prevent epidemic diseases with less financial burden, and things obtainable easily according to individuals' situation were mentioned for anybody to overcome the emergent situation of epidemic diseases. Fourth, methods for praying to God were suggested for practitioners to work with sincere spirit and to keep themselves from epidemic diseases.

  • Tinted with ontological concern, Ted Hughes passes through an existential climate, eventually confirms death( or nothingness) as the new foundation of his poetry, and explores the various paradoxical effects of nothingness. Nihilism, fraught with rather negative and traumatic themes such as death, melancholy, and despair can, however, generate being (even in multiple modes), animalistic vitality, and insubstantial specters. Among these new functions of nothingness animality and spectrality are the most notable in Hughes's poetry. A considerable number of animals and bioorganisms that Hughes introduces exhibit the enormous energy derived from the dignity of death, from subversive challenges against the established hierarchy, and from new and dynamic multifaceted sources of nothingness. In other words, Hughes's animals, yield surplus power beyond themselves, as if they are demi-gods; in short, they feature the sublime as unidentified terrifying effects of nothingness. In a sense, animality means allowing some level of violence without legal sanction. Hughes inaugurates this kind of all bigotry-eradicating violence and attempts to subvert higher beings such as humans and gods, and existing doctrines: thrushes rise up against the animal and human worlds; a rush of ghostly crabs at night press through the human world. Hughes also resists the highest being, God, employing the technique of rewriting God's theology. Dirty, anomalous crows attack, subvert, and dismember the delicate, indurate, and thorough system of logos. Hughes, of course, does not place the animals merely in lofty regard, aware of the ulterior deprivation of the sublime animality, the trace of existential negativity. Thus, a seemingly omnipotent crow can become a mere beggar guzzling ice cream from the garbage bin on the beach. In addition, the violent and dignified aspects of nothingness can be transformed to reveal the thin and trivial traits as unreliable specters. Dark, heavy, and terrible nullity lessens its own volume and mass, and exposes the airy waves of shadows or specters. However, owing to nullity's untraceable track, the scarcity and unfamiliarity of the phantoms inversely display their foreign gigantic effects such as fantasy and violence.

  • This paper will examine the way Philip Larkin as a modern poet views unfavorable but inescapable past experiences with ambivalent attitudes. Larkin has written poems which concern the matters of time, aging, and death. Out of these related themes, the past has offered one major subject for Larkin's poems. Those poems on his personal experiences, coming out of his deep interest in the past and in the relationship the past has with his present and future life, reveal much of the poet's personality. Because of Larkin's conflicting attitudes towards past life, however, the poems about his past create both ambivalence and attraction in the readers' minds. The unusual restraint of emotion and conflict revealed in the poems about past life render rare modern lyrics that are unlike exuberant romantic poems.

  • Background: Foodborne pathogens are a growing concern with respect to human illnesses and death. There is an increasing demand for improvements in global food safety. However, it is a challenge to detect and identify these harmful organisms in a rapid, responsive, suitable, and effective way. Results: Rapid developments in biosensor designs have contributed to the detection of foodborne pathogens and other microorganisms. Biosensors can automate this process and have the potential to enable fast analyses that are cost and time-effective. Various biosensor techniques are available that can identify foodborne pathogens and other health hazards. Conclusions: In this review, biosensor technology is briefly discussed, followed by a summary of foodborne pathogen detection using various transduction systems that exhibit specificity for particular foodborne pathogens. In addition, the recent application of biosensor technology to detect pesticides and heavy metals is briefly addressed.

  • The land transportation is the most common way to transport passengers as well as freight among other mode of transportations and consequently more likely to be constructed for faster and convenient travel In this regard, the demand for tunnel constructions will be increasing and the safety inside the tunnel will be considered major concern more than ever. In this paper, we show probabilistic methodology to calculate the personal risk of each evacuee starting from a different location in a tunnel on fire. Passenger evacuation time and smoke spread time are both assumed to be continuous random variables having specific distributions. The evacuation of passengers at each location and the safety facilities inside the tunnel are also crucial factors to calculate the probability of death.
