  • 본 연구는 춘파 야생화초지의 생육특성, 계절개화분포 및 식생비율을 구명하고자 시험하였다. 공시초종은 기본초종인 잔디형 목초로 Sheep fescue (Azure), 야생화 초종으로는 국내산 야생화 4종과 외국산 야생화 29종 등 총 34종을 공시하였다. 시험은 충남대학교 초지시험 포장에서 2008년 3월부터 2009년 12월까지 수행하였으며, 얻어진 결과는 다음과 같다. 야생화의 초장은 8~60 cm 범위로 상하 공간배치는 양호한 편이었으며, 꽃색은 9가지로 다양하게 개화되었으나 8월, 9월 및 10월에는 1~3가지로 편중되었다. 개화는 5~6월에 편중되었고 8월부터는 야생화의 개화 및 영속성 유지가 상당히 어려웠다. 그러나, 2년차(2009)에는 월동 후 일년생 야생화초종의 식생 감소로 야생화의 꽃색, 계절분포 및 영속성이 문제시 되었다. 야생화초지의 연평균 식생비율은 야생화, 잔디형 목초 및 잡초가 각각 1년차(2008)에는 24%, 62% 및 14%이었고, 2년차(2009)에는 각각 16%, 69% 및 15%를 유지하였다. 이상의 결과로 보아 춘파 야생화초지의 경우, 파종당년보다는 2년차에 야생화의 꽃 색, 계절개화분포 및 영속성을 유지할 수 있는 방안이 중요하다고 하겠다.

  • 본 연구는 sheep fescue 70%와 야생화 30%의 파종비율로 조성한 야생화초지의 생육특성, 계절분포 및 식생비율을 구명하고자 충남대학교 내 초지시험포장에서 2007년 10월부터 2009년 12월까지 수행하였다. 공시초종은 기본초종인 잔디형 목초로 sheep fescue (Azure)와 국내산 야생화 4종과 외국산 야생화 29종 등 총 33종을 공시하였다. 1년차(2008) 야생화의 개화당시의 평균초장은 1년차 29.9 cm, 2년차 38.4 cm 이었다. 꽃 색은 9가지로 다양하게 개화되었으나 8월, 9월 및 10월에는 3가지색(yellow, white, pink)으로 편중되었다. 개화는 5~6월에 편중되었고, 8월부터는 야생화의 개화 및 영속성유지에 상당한 어려움이 있었다. 특히, 2년차(2009)에는 월동후 일년생 야생화초종의 식생감소로 야생화의 꽃 색, 계절분포 및 영속성이 문제시 되었다. 야생화초지의 연평균 식생비율은 야생화, sheep fescue 및 잡초가 각각 1년차(2008)에는 25%, 61% 및 14%이었고, 2년차(2009)에는 각각 22%, 65% 및 13%를 유지하였다. 이상의 결과로 보아 sheep fescue와 야생화의 파종비율을 70:30%의 비율로 야생화초지를 조성할 경우는 공원 및 하천변과 같은 평탄지를 대상으로 야생화에 의한 경관유지와 sheep fescue에 의한 녹색공간을 동시에 유지하는데 더 적합할 것으로 판단된다.

  • It is known that the role of informal support for elderly women is critical to their physical and mental health, adjustment in old age, and their overall life satisfaction. Elderly women's situation such as social losses, widowhood, living alone, and geographic relocation etc. may result in a need for more informal supports for elderly women's health than ever before. Particularly, women's same-sex friendships were rated higher for overall quality, intimacy, enjoyment, and nurturance. Unlike a generally accepted notion that later life for women is a time of isolation and loneliness, elderly women tend to maintain and reestablish their friendship regardless their marital status and living situation. Although studies on informal support for elderly women were inconclusive in many ways, elderly women's friendship tends to be stable despite of changing health status and life events. The relative importance between daughters and friends was also controversial. This study suggests that more research with reliable measurements is necessary for the practical prevention and intervention program of elderly women's health on this issue.

  • The purpose of the present study was to investigate the view that animism is a result of immature concepts of life. Two studies were conducted for this purpose Study I examined developmental trends in animistic thinking and Study II examined children's knowledge of living things. The subjects of Study I were 10 males and 10 females at each level, 6, 8, 11 and 14 years of age and university students, for a total of 100 subjects. The subjects of Study II were 9 boys and 9 girls at each age level, 6, 7 and 8 years of age and university students, for a total of 78 subjects. According to the results of study I and study II, animistic thinking decreased up to middle childhood but increased at later childhood and adulthood. The conception of living things was acquired at 7 years of age. All things considered, there was no evidence that animism is a result of immature concepts of life.

  • With accumulated nursing research results from older adults, refined middle range nursing theories are evolving in gerontological nursing area. Three middle range nursing theories and framework were reviewed and described. Life transition framework for older adults were developed through research related to relocation and other transitions taken place in later life. Self-efficacy exercise model was developed by extensive research related to rehabilitation of older adults based on self efficacy expectations and outcome expectations concept from social cognition theory. Need-Driven dementia-compromised Behavior (NDB) model was developed by a group of nursing scholars studying dysfunctional behaviors of demented older adults. All of these theories are approaching to practice theory by developing interventions and nursing therapeutics. There are more needs to develop theories for specific gerontological nursing phenomena such as delirium, end of life and self integrity.

  • This study reports the detection and genotyping of the first clinical case of bovine anemia due to Theileria orientalis group (BATOG) in non-grazed dairy cow in upper South Korea. Blood and serum tests revealed anemia and hyperbilirubinemia from animal showing clinical symptoms, and later confirmed as piroplasmosis-positive. Follow-up surveillance on the herd revealed 2 asymptomatic cows with anemia. The three animals were confirmed theileriosis-positive and genotyping revealed the clinical and one of the asymptomatic cases have Chitose, while the other has Ikeda genotype. Clinical BATOG cases were rarely reported worldwide, and asymptomatic animals left untreated could serve as parasite reservoir.

  • Recently, the survival of the high-risk population of preterm infants has steadily improved, and the severity of prematurity is a growing threat of gestational-age-related fatal conditions. Posthemorrhagic hydrocephalus (PHH) is the most common but serious neurological complication in premature infants, which can have life-threatening consequences during the acute phase in the neonatal period and life-long psychomotor and cognitive sequelae in their later life. Although neonatologists, pediatric neurologists, and pediatric neurosurgeons have investigated a diversified strategy for several decades, a consensus on the best management of PHH in premature infants still must be reached. Several approaches have tried to reduce the incidence of intraventricular hemorrhage (IVH) and mitigate the effect of IVH-related hydrocephalus. This paper reviews and discusses the clinical feature of PHH in premature infants, general/nonsurgical management of prematurity for IVH prevention, and posthemorrhagic management, and how and when to intervene.

  • Major depression is a devastating disorder of which lifetime prevalence rate is as high as up to 25% in general population. Although the etiology of the disorder is still poorly understood, it is generally accepted that both genetic and environmental factors are involved in the precipitation of depression. Stressful lifetime events are potent precipitating environmental factors for major depression and early-life stress is in particular an important element that predisposes individuals to major depression later in life. How environmental factors such as stress can make our neural networks susceptible to depression and how those factors leave long-lasting influences have been among the major questions in the field of depression research. Epigenetic regulations can provide a bridging mechanism between environmental factors and genetic factors so that these two factors can additively determine individual predispositions to major depression. Here we introduce epigenetic regulations as candidate mechanisms that mediate the integration of environmental adversaries with genetic predispositions, which may lead to the development of major depression, and summarize basic molecular events that underlie epigenetic regulations as well as experimental evidences that support the active role of epigenetic regulation in major depression.

  • Multiple myeloma is malignant neoplasm of plasma cells. Mandible lesions are rarely the first symptoms of multiple myeloma. While sensory dysfunction and pain are the main symptoms of traumatic trigeminal neuropathy, the same oral symptoms can appear in cases of multiple myeloma with developed mandible lesions. In addition, if the radiological osteoporosis or lytic lesion is seen in older patients, further examination is required to find the cause of the symptoms. In this paper, we present a case that was tentatively diagnosed as traumatic trigeminal neuropathy after left third molar extraction, but later confirmed as multiple myeloma.
