본 연구는 훼스큐 초종 간 발아력, 발아세 및 발아 피크기간을 조사하고자 수행되었다. 공시재료는 TF, CF, CRF, HF 및 SF 5종류에서 선정한 9품종을 이용하였다. 발아실험은 국제종자검정협회 요구 조건인 ISTA 변온 조건에서 수행하였으며 조사는 치상 후 1일 간격으로 발아율을 조사하여 자료를 분석하였다. 훼스큐 속 잔디 종자의 발아력, 발아세 및 발아 피크 기간은 초종 및 품종에 따라 통계적으로 유의한 차이가 나타났다. ISTA 변온 환경에서 종자 발아력은 62.25~96.75% 사이로 나타났다. 이중 가장 양호한 초종은 TF 'Olympic Gold' 품종으로 최종 발아율이 96.75% 이었으며, 가장 저조한 초종은 CRF 'Audubon' 품종으로 62.25% 이었다. 초종 간 종자 발아력은 세엽형 보다 광엽형인 TF 초종이 더 우수하였으며, 세엽형 훼스큐 초종 간 발아력은 HF>SF>CF>CRF 순서로 나타났다. 훼스큐 잔디 종자의 발아세도 초종 및 품종에 따라 차이가 유의하게 나타났는데 파종 후 시간이 경과함에 따라 초종 간 발아세 속도 차이가 크게 증가하였다. 발아율이 50%에 도달할 때까지 소요되는 50% 발아세 속도부터 80% 발아세 속도까지 전체적인 초종 간 발아세 경향은 TF 초종이 가장 빨랐고, CF 및 HF 초종은 중간 정도, 그리고 CRF 및 SF초종이 가장 느리게 나타났다. 훼스큐 속 초종 간 발아피크 기간은 광엽형 TF 품종이 평균 1.17일로 세엽형 품종보다 훨씬 더 짧았다. 그리고 세엽형 훼스큐의 발아 피크기간은 2.80~12.36일 사이로 초종간 차이가 크게 나타났다. 세엽형 훼스큐 초종 간 우열관계는 HF, SF < CF < CRF 순서로 발아 피크 기간이 더 길어졌다. 본 실험 결과 훼스큐 속 초종 간 발아력, 발아세 및 발아 피크 기간을 종합적으로 고려 시 ISTA 변온에서 잔디 조성 속도의 우열관계는 TF > CF, HF > SF > CRF 초종 순서로 나타났다. 그리고 전체 공시 품종에서는 TF 'Arid III' 품종이 가장 우수하였고, 반대로 CRF 'Audubon' 품종이 가장 불량한 것으로 판단되었다. 즉 훼스큐 속 초종 및 품종에 따라 이러한 발아속도, 발아패턴 및 특성 차이가 크게 나타날 수 있기 때문에 골프장 등 잔디밭 조성 시 적절한 초종 및 품종 선택과 함께 사용 전에 발아특성을 파악하는 것은 실무적으로 대단히 중요하다.

The main objective of this study was to evaluate the effects of control-release fertilizer (CRF) on pollutant loadings from a small watershed. The Baran watershed, 386 ha in size, was selected as the study site, and the AGNPS (Agricultural Non-point Source Pollution) model was used to evaluate the effects of fertilizer types. Digital maps of digital elevation (DEM), slope distribution, channel, flow direction, landuse, soil, and curve number were extracted from the study watershed. Model parameters related to hydrology and water quality were calibrated and validated by comparing model predictions with the observed data collected for 2 years (1999 to 2000). Calibration and validation resulted in $R^2$ values of 0.75-0.91 for all the water quality parameters. All the paddy fields (21.2 %) of the study watershed were sprayed by either CRF or NPK (standard fertilizer). In CRF application, total nitrogen (TN) load was 4.9% less than NPK application, however total phosphorus (TP) load was 0.7 % more than NPK application. In CRF application, considering only paddy fields in the study area, TN load was 38.7 % less than NPK application. Using CRF in paddy fields could be one of the ways to reduce pollutant loadings from agricultural watersheds, however, in order to confirm it, more researches about effects of using CRF are necessary.

Purpose: This pilot case series study aimed to evaluate the efficacy of continuous radiofrequency (CRF) application on dorsal root ganglia (DRG) to reduce spasticity of spinal cord lesion (SCL) patients. Methods: We performed CRF procedures on DRG in 8 subjects (7 males; mean age 39 years, range 31-53 years) with intractable spasticity that impeded activities of daily living and caregiving, although they had maximal tolerable doses of anti-spastic medications and active rehabilitative treatment. All subjects underwent CRF (90 seconds at $90^{\circ}C$) at multiple lumbosacral and/or cervical DRG. Muscle tone of the extremities was measured by the modified Ashworth scale (MAS) before and one month after procedures. Functional goals were established at baseline, and subjects' satisfaction levels were categorized one month after procedures. Results: A total of 54 CRF treatments were performed in 8 patients. In all patients, we found some improvement in muscle tone measured by the MAS. Six patients reported themselves satisfied with their current status at one month's post-treatment, and 2 patients were fairly satisfied with their gait pattern. In 3 patients, neuropathic pain was present after CRF on DRG. In 1 lumbar case, the pain subsided after several days, and the other 2 cervical cases suffered from tolerable neuropathic pain treated with anti-convulsant medication. Conclusion: CRF on DRG might be a promising alternative treatment to reduce spasticity in SCL patients. Further well-designed clinical trials on the efficacy and safety of CRF application on DRG are needed.

Sensorineural hearing loss is frequently found in patients with chronic renal failure (CRF). There have been many efforts to elucidate the etiologic factors of hearing loss in patients with CRF. However, there was not any clear identified cause of hearing loss. This study was undertaken to evaluate the activity of mitochondrial respiratory chain (MRC) in CRF patients with hearing impairment. To determine MRC activity, peripheral blood cells were obtained from CRF patients with hearing impairment receiving dialysis and normal subjects without any hearing problems. MRC activity of complex I and complex III was measured by the Trounces method. In MRC activities between the normal subjects group and CRF patients with hearing problems, the complex I and III activities of CRF patients with hearing problems were 63% and 85% compared with normal subjects (p<0.01). These results suggest that the activity of MRC may be implicated in the underlying mechanism of the hearing impairment in CRF patients, through mitochondrial DNA mutations at MRC complex I region with a decrement of MRC activity.

Purpose: The purpose of this study was to test a Winningham's psychobiologic entropy model (PEM) on cancer related fatigue (CRF) among patients with solid tumors. Methods: Participants consisted of 213 patients with solid tumors recruited from December, 2012 through June, 2013, in a university hospital, in Hwasun, South Korea. Primary symptoms, adjustment, physical activity, status of nutrition and fatigue were measured using structured questionnaires. Collected data were analyzed using SPSS 21.0 and AMOS 21.0 programs. Results: The modified model tested provided a reasonable fit to the data ($x^2=65.80$ [df=30, p<.001], TLI=.92, CFI=.95, RMSEA=.08, SRMR=.07). Primary symptoms (dyspnea, anxiety, depression and insomnia) had direct positive effects on CRF. Adjustment and status of nutrition showed indirect negative effects on CRF. However, the impact of physical activity was not significant. These variables explained 49.2% of the variance of CRF among solid tumor patients. Conclusion: The findings demonstrate that the tested model explain some CRF among solid tumor patients and warrant future research considering the cancer-related clinical factors of the given population.

Purpose: The research aims to understand the lived experience of the caregivers of chronic renal failure(CRF) patients and its essential meaning. The results of the study can be used as basic materials for developing comprehensive intervention methods of care givers of CRF patients. Method: The research used van Manen's hermeneutic and phenomenological research methods in order to describe the lived experience and to understand its meaning. It concentrates on the understanding the essence of experience and consists of existential survey, hermeneutic and phenomenological reflection and hermeneutic writings. Participants in this research were five women care givers of CRF patients who had hemolysis at C university hospital in a metropolitan city, the period of data collection was from July 27 to Sep. 4, 2004 and major data of results in the following 5 essential themes. "sole responsibility for the patient enduring everything", "creating their own field", "heavy and painful life without hope of their private life", "wishing not to be inherited and consoling each other". Conclusion: The above findings point out that the experience of care givers of CRF patient affected and changed all parts of an individual life and his or her family life. Therefore, it suggests that total family nursing care must be considered in order to provide the holistic caring for CRF patients and their care givers.

The purpose of this study was to discover the experience of hemodialysis which clients confronted hemodialysis at the same time as CRF diagnosis and to understand the nature and meaning of their crisis experience. The research subjects were 6 clients receiving hemodialysis in Seoul from Jan. 1996 to Jul. 1996. Data were collected by informal indepth interview and participant observation. Content Analysis(by Seaman & Verhonick, 1982; Woods & Catanzaro, 1988) was applied to collect similar contents and common experience in order to derivate concepts and categories for better understanding of their hemodialysis experience. As a result, 6 categories derivated to indentify their hemodialysis experience of the CRF clients-confronted hemodialysis at the same time as CRF diagnosis-were as follows: 1) The category of shocking crisis composed the concepts of shock, amagement and suffocation. 2) The category of denial composed the concepts of disease refusal and hemodialysis refusal. They repeatedly visited hospitals or didn't visit hospital in order to refuse disease, then depended on folk remedy or shamanistic method. 3) The category of severe anxiety composed the concepts of abandoned feeling, shame, resentment, neurosis and anger. 4) The category of depression composed the concepts of grief, suffering of unfairness, tearing, desire to death. 5) The category of powerlessness composed the concept of hopelessness. 6) The category of resigned acceptance composed the concepts of resignation and acceptance. In this study, the CRF clients who confronted hemodialysis at the same time as CRF diagnosis experienced six stages in accepting hemodialysis but these stages were mingled simultaneously and went on.

We perform the task of video object segmentation by incorporating a conditional random field (CRF) and convolutional neural networks (CNNs). Most methods employ a CRF to refine a coarse output from fully convolutional networks. Others treat the inference process of the CRF as a recurrent neural network and then combine CNNs and the CRF into an end-to-end model for video object segmentation. In contrast to these methods, we propose a novel higher-order CRF model to solve the problem of video object segmentation. Specifically, we use CNNs to establish a higher-order dependence among pixels, and this dependence can provide critical global information for a segmentation model to enhance the global consistency of segmentation. In general, the optimization of the higher-order energy is extremely difficult. To make the problem tractable, we decompose the higher-order energy into two parts by utilizing auxiliary variables and then solve it by using an iterative process. We conduct quantitative and qualitative analyses on multiple datasets, and the proposed method achieves competitive results.
