Neuroblastoma arises from the embryonic tissue of the adrenergic rest. It is commonly found in children and mostly in nonrenal tissue. We present a case of intrarenal neuroblastoma which was initially thought to be a Wilms' tumor. The patient was a 18 months-old girl treated with radical nephrectomy and adjuvant chemotherapy after operation. The neoplasm within the kidney in children cannot always indicate Wilms' tumor. Neuroblastoma of the adrenal gland or retroperitoneal tissue may often compress or invade the kidney directly or arise from the kidney. Clinical aspects that differentiate between neuroblastoma and Wilms' tumor are discussed with a review of the literatures.

In this study, the analysis was conducted in the aspect of non-hardened concrete of Ternary Mixed Aggregates, and it was determined that flowing and amount of air increased as the mixing combinations of RS increased. However, it is difficult to see the phenomenon only as a result of increasing mixing combinations of RS, and it is thought that the influence of CS and SS also plays a large role. For later analysis, we plan to conduct research on compressive strength and shrinkage according to age, and analyze more suitable mixing combinations.

Compare western medicine report and books which refer to Gout with Oriental medicine books which refer to Tongp'ung(痛風). The results of studying about Gout and Tongp'ung(痛風) were summarized as follows. l. Dangyesimbub(丹溪心法) was printed in 1481 and also the first book which referred to Tongp'ung(痛風). 2. Donwonsipjonguiso(東垣十種醫書) was printed in 1592 and also Tongp'ung(痛風) was recorded like gout especially in cause of disease. 3. Ancient times, Affection by exopathogen and six kinds of natural factors were persisted the cause of Tongpung(痛風), later generation drink, diet and labor were persisted. 4. In Beunjungrok(辨證錄) and susyebowon(壽世保元), there were similar expressions about gout, for examples interval phase and chornic tophaceous. 5. In Uihakjongjon(醫學正傳) and Manbeunghoechun(萬病回春) insisted that gout patients had to control their food especially meat, fish snd drink. 6. According to the cause(Pung(風), Han(寒), Sub(濕)), doctor classified Bi(痺) first was Hangbi(行痺), second was Tongbi(痛痺) and last was Chakbi(着痺). 7. Doctors thought that Tongp'ung(痛風,) was not Hangbi(行痺) and Chakbi(着痺) but it was Tongbi (痛痺). Especially in pain, they thought it was similar to Bakhoyeukjolp'ung(白虎歷節風).

Droplet distribution of LCP(Vectra 950) and PET blend by repeated extrusion was examined through morphology analysis. Repeated extrusion was respectively proceeded twice and three times with blending condition and droplet distribution of only once extrusion sample showed uniform shape. However, droplet size of twice and three times extrusion samples increased and it was confirmed that droplets were concentrated on the center of specimens. It is thought that this phenomena were due to the compatibility and viscoelastic behavior of LCP/PET blend. Finally, it is thought that fiber manufacturing of different diameter is possible from spinning of repeated extrusion LCP/PET blended chip under same spinning condition.

This study explored different concepts by handing out the questionnaires asking the 6 students of the second year of junior high school who had no lesson on cycle "which words related to cycle are suggested?" In regard to the stimulation of the word 'cycle', students relate it to different fields that they learn at school such as biology, environmentology, and earth science. The analyzed results from the answers by students are as follows. First, it resulted in from analysis on the questionnaire and the half-structured interviews that students were unable to expand the concept of cycle to the scientific concept, and perceived it fragmentarily. Secondly, their understanding on the system of the earth was low and they understood the concept of cycle with a unilinear thought rather than a systematic thought. Therefore, we need to synthesize the students' unilinear thoughts on cycle shown through this study and an effective educational strategy for their continuous, systematic thoughts, is essential.

Depression and executive dysfunction are common neuropsychiatric sequelae of stroke. Patients with stroke are more predisposed to depression and executive dysfunction compared to patients with similar degree of physical disability. Both depression and executive dysfunction are also associated with poor prognosis such as high mortality and delayed recovery after stroke. Complex neurobiological and anatomical mechanisms are associated with the development of depression and executive dysfunction after stroke. Activation of pro-inflammatory cytokines is thought to be associated with onset of depression, whereas injuries in frontal-subcortical circuit are thought to be a link between depression and executive dysfunction. Early detection of depressive symptoms and both pharmacological and non-pharmacological treatment would be helpful. In this review paper, the authors investigated 1) biological and neuroanatomical substrate for poststroke depression and executive dysfunction, 2) the relationship and common etiopathology for poststroke depression and executive dysfunction, and 3) pharmacological and non-pharmacological treatment for poststroke depression. The contents of the paper are as follows : the prevalence, clinical manifestation, and biological etiology for poststroke depression, neuroanatomical abnormalities as a common etiological factor for depression and executive dysfunction, pharmacotherapy and non-pharmacological approach.

Purpose: The purpose of this study was to examine nursing students' attitude toward death and perception on hospice care. Methods: The survey was performed with 277 nursing students in three universities in Daegu and Busan. The data was collected by questionnaires and were analyzed using descriptive statistics. Results: Regarding the attitude on death, 93.9% of the subjects had ever thought about death. They worried about separation and sadness with family (39.7%). About half (48.7%) of the subjects considered death as a final process of the life. With regard to the perception of hospice, 93% of the subjects heard about hospice through books or nursing courses (83.8%). The best hospice management institution was considered the one run by religious groups or non-profit organizations with government support (33.9%). Ideal model of hospice setting in Korea was hospital or institution specialized with hospice care (47.7%). The barriers the subjects thought to effective hospice care in Korea was the lack of the public consensus on the need for hospice program (37.9%). The average perceptions about the purpose of hospice care was 4.38, whereas, the average of the need of hospice care was 4.06. Conclusion: The findings of the study provides the basis for expanding nursing practice and education related to hospice care.

The most common genetic disorder Down syndrome (DS) displays various developmental defects including mental retardation, learning and memory deficit, the early onset of Alzheimer's disease (AD), congenital heart disease, and craniofacial abnormalities. Those characteristics result from the extra-genes located in the specific region called 'Down syndrome critical region (DSCR)' in human chromosome 21. In this review, we summarized the recent findings of the DYRK1A and RCAN1 genes, which are located on DSCR and thought to be closely associated with the typical features of DS patients, and their implication to the pathogenesis of neural defects in DS. DYRK1A phosphorylates several transcriptional factors, such as CREB and NFAT, endocytic complex proteins, and AD-linked gene products. Meanwhile, RCAN1 is an endogenous inhibitor of calcineurin A, and its unbalanced activity is thought to cause major neuronal and/or non-neuronal malfunction in DS and AD. Interestingly, they both contribute to the learning and memory deficit, altered synaptic plasticity, impaired cell cycle regulation, and AD-like neuropathology in DS. By understanding their biochemical, functional and physiological roles, we hope to get important molecular basis of DS pathology, which would consequently lead to the basis to develop the possible therapeutic tools for the neural defects in DS.

The purpose of this study was to investigation the elementary school teachers' perception in STEAM(Science, Technology, Engineering, Arts, Mathematics) Education. For this study, 93 elementary school teachers who have taught mathematics/science in gifted class were selected and a fifteen items questionnaire designed to elicit teachers' perception of steam education was to administered to them. The major findings are as follows: First, the ratio of teachers who understood a steam education exactly is very low. But teachers have positive thoughts about the need of steam education. Second, teachers thought that steam education has a good effect on elementary education. Third, teachers thought that steam education will be an alternative teaching and learning method. Fourth, teachers have negative thoughts to participate in class work related on steam education. To improve negative attitudes on steam education, incentives for teachers seems to be required. In order to spread steam education among the elementary school teachers successfully, the expansion of school facilities, administrators and staff in mind, improving financial support, strengthening education through the development of content and teaching strategies were analyzed as a challenge.

Objectives : The aim of this study is to find a desirable way for acupuncture treatment of Vascular Dementia. Methods : The author reviewed several literatures related with Vascular Dementia. Based on the literatures, the author interpreted the causes and symptoms of Vascular Dementia on viewpoint of three yin and three yang. In addition, research about desirable way for acupuncture treatment was carried out. Results and Conclusions : The cause of Vascular Dementia is thought to be the functional weakness of lesser yin, the heart meridian. Also, the related-factors represent functional excess of reverting yin and greater yin, as well show functional weakness of lesser yin. Accordingly, for the acupuncture treatment of Vascular Dementia, it is necessary to tonify lesser yin. On the other hand, the activation of lesser yang is thought to be helpful.
