목적: 본 연구의 목적은 섬망이 있는 말기암환자에 있어 진정제의 투약 투약 관련 특성을 파악하고, 진정제 투약군과 비투약군 간의 생존기간의 차이를 확인하기 위함이다. 방법: 본 연구는 2012년 1월부터 2013년 12월까지 B 광역시 소재 P대학교병원에서 응급실과 수술실, 중환자실을 제외한 병동에서 임종한 암환자 900명 중 경과기록지, 간호기록지를 통해 섬망선별 도구인 Nu-DESC를 이용하여 섬망이 있었던 말기암환자 240명을 대상자로 선정하였다. 투약기록지를 통해 진정제인 haloperidol, diazepam, lorazepam을 정맥 또는 근육주사로 규칙적이거나 필요 시 투여한 횟수를 조사하였다. 결과: 연구 대상자의 섬망기간은 최소 1일에서 최대 61일까지 나타났고, 중앙값은 5일이었다. 연구 대상자에게서 나타난 섬망 특성은 부적절한 행동이 35.0%로 가장 많았다. 연구 대상자의 연령(F=3.96, P=0.021), 원발암의 종류(F=3.31, P=0.010), 항암치료 여부(t=-3.44, P=0.001)에 따른 섬망기간이 유의한 차이가 있었다. 연구 대상자가 진정제를 복용한 경우는 72.1%이었고, 투약된 진정제의 종류는 haloperidol이 59.6%로 가장 많았다. 진정제 투약군의 생존기간은 평균 16.85일, 비투약군은 9.37일로 나타났으나 이는 통계적으로 유의하지는 않아(t=1.766, P=0.079) 진정제 투약이 생존기간에 영향을 미치지는 않았다. 결론: 말기암환자의 섬망 발생 시 진정제 투약이 생존기간에 미치지 않았다. 이러한 결과를 바탕으로 생명단축의 윤리적 문제로 인해 진정제 사용을 꺼려하기 보다는 증상완화를 위한 진정제 치료를 적극적으로 권유할 수 있다. 또한 섬망은 가족이나 의료진과의 의사소통 장애를 유발할 뿐 아니라 환자나 가족들에게 스트레스로 작용하며 돌봄에 대한 부담감을 가중시키므로, 적절한 진정제의 투여는 말기암환자와 가족의 안위를 위해 적극적으로 추천하는 바이다. Purpose: This study analyzed the difference in survival time of patients with delirium according to sedative medication. Methods: From January 2012 through December 2013, a retrospective cohort study was performed using the electronic medical records (EMR) of Pusan National University Hospital. Among 900 patients who died from cancer, we selected 240 who suffered delirium based on the EMR. The Nu-DESC delirium screening test was used to diagnose delirium. Results: The median length of delirium period was five days. Delirium characteristics were dominated by inappropriate behaviors (35.0%). Sedatives were administered in 72.1% of the cases. The most frequently used sedative was haloperidol which was used in 59.6% of cases. The delirium period significantly differed by patients' age (F=3.96, P=0.021), cancer type (F=3.31, P=0.010), chemotherapy (t=-3.44 P=0.001). The average survival time was 16.85 days for the sedative medication group and 9.37 days for the non-medication group, which, however, was not significant (t=1.766, P=0.079). Conclusion: In this study, the use of sedatives did not affect patients' survival time. Thus, appropriate sedative medication can be positively recommended to comfort terminal cancer patients and their families.

OFDMA/TDD 시스템의 하향링크 빔형성 송신기 설계

박형숙,박윤옥,김철성,Park Hyeong-Sook,Park Youn-Ok,Kim Cheol-Sung 한국통신학회 2006 韓國通信學會論文誌 Vol.31 No.5a

논문은 OFDMA/TDD 시스템에서 하향링크 빔 형성 송신기의 효율적인 구조와 설계 변수의 최적화에 대하여 고찰하였다. 다수의 송신 안테나를 사용하는 하향링크 빔 형성 송신기 설계에 있어 다수의 사용자에 대한 효율적인 빔 형성 구조 설계와 송신기 블록의 word-length 는 송신기의 성능과 하드웨어 복잡도 측면에서 중요한 설계 변수가 된다. 본 논문에서는 기지국 수신에서 사용자 구분 없이 부반송파별 가중치만 메모리에 저장하고, IFFT 입력의 부반송파 단위에서 사용자에 따라 할당된 부반송파의 가중치를 고속으로 계산하여 적용하는 효율적인 빔형성기 구조를 제시하였다. 또한, 고정 소수점 시뮬레이션을 통하여 최적의 설계 변수를 분석하였다. 제시한 구조는 프레임 당 최대 사용자 수에 비례하게 메모리를 줄일 수 있으며, 또한 기지국 수신에서 사용자 제어 없이 FFT 출력을 바로 송신에 적용하여 OFDM 한 심볼의 처리 시간을 줄일 수 있고 송신기에서 빔 형성 계산은 별도의 처리 시간을 요구하지 않는 장점이 있다. This paper presents the efficient structure and parameter optimization of downlink beamforming transmitter in OFDMA/TDD system. To design downlink beamforming transmitter for multiple transmit antennas, an efficient beamforming structure for multiple users and the choice of word-length of each block are critical in the aspect of its performance and hardware complexity. We propose an efficient beamforming scheme, which stores the weights of subcarriers into memory without user identification at the receiver of base station and calculates the weights for corresponding user in a subcarrier unit of IFFT input at high speed. Also, we obtain the word-length of main data path and other design parameters by fixed-point simulation analysis. The proposed architecture could reduce the memory size proportional to the maximum number of users per frame, and the processing time of an OFDM symbol at the receiver of base station without the need of additional processing time for calculating the weights at the transmitter.

박형숙(Hyoung-Sook Park),강영희(Young-Hee Kang) 한국식품영양과학회 2004 한국식품영양과학회지 Vol.33 No.4

인슐린 작용을 강화시키는 LMWCr의 발견과 크롬 결핍과 관련있는 포도당 불내성(glucose intolerance)이 크롬 투여시 반응을 보여준 임상적 증명 이후, 크롬은 확실한 필수 영양소로 인식되고 보조제로 사용되고 있다. 시험관 실험에서 고농도의 3가 크롬을 배양 세포에 노출 시, 일부 연구 결과에서 염색체이상 유발과 변이원성 효과가 발견되긴 하였으나 이는 비타민 A, D, 니코틴산, 셀레늄 등과 같은 많은 다른 영양소의 과잉 섭취 시 독성 효과를 나타내는 정도로 해석되며, 시험관 실험 결과들이 발암성의 증거로 해석되지는 않는다. 3가 크롬을 경구 보조제로 투여된 임상 치료에서 환자들은 독성효과를 보이지 않았으며, 혈장 내 크롬 수치가 비 투여된 사람들에 비하여 조금 높았다. 크롬을 TPN 형태로 투여받은 환자들에게서도 우려했던 신체ㆍ정신적 효과와의 상관 관계가 없었으며 신기능부전을 나타낸 경우는 신장 독성을 주는 약들을 함께 복용한 경우로서, 우려되는 부작용은 없는 것으로 인정된다. 임상학적, 실험적으로 사용된 3가 크롬의 용량은 ESADDI에 규정된 범위 50~200 ㎍/day에서 전혀 독성을 나타내지 않았으며, 일반적인 사용에 기준이 될 것이다. EPA는 모든 관련 자료들을 검토한 후에 크롬의 참고용량 (RfD) 수치를 70 ㎎/day로 결론지었으며, 다른 영양소들의 용량과 비교했을 때 대단히 넓은 수치이다. 3가 크롬은 당뇨병, 임신성 당뇨병, 인슐린 내성, 비정상적 지방대사를 개선시키기 위한 영양소로서 가능성을 가진다. 또한 크롬의 보충은 제Ⅱ형 당뇨병과 다양한 심혈관계 질환을 예방하거나 치료하는데 가장 유용한 것으로 밝혀졌다. 앞으로는 크롬 보조제 사용시, 일부 연구자들이 3가 크롬 1000 ㎍/day의 안전성을 입증한 것과 같이 용량을 늘려 임상실험을 시도한 후 안전과 효능을 증명하는 것이 필요하다. Chromium has been known to be involved in the glucose metabolism, and hence the utilization of cellular glucose is impaired in the chromium deficiency. Chromium has been recognized as an essential nutrient since the finding of low-molecular-weight Cr-binding substance (LMWCr) as a biological modifier of insulin action. Clinical chromium deficiency associated with glucose intolerance that respond to the administration of chromium. The major impediment to the use of orally administered chromium is poor absorption of trivalent chromium in its inorganic form. Trivalent chromium is more available in yeast and, more recently, as chromium picolinate for oral absorption. The widespread use of these supplements has resulted in controversy regarding chromium's role as a nutrient, its use for treatment of insulin resistance, and its potential toxicity. Most recent evidence strongly supports the conclusion that there is little fear of toxic reactions from chromium consumption. This report reviews the evidence for the potential toxicity of chromium supplements in contrast with its usefulness as a nutrient or therapeutic agent in the treatment or prevention of insulin resistance.

The purpose of this study was to determine the meaning of the adaptation experiences of new ICU nurses who were working in a newly established university hospital. The study was based on phenomenological research methodology. Method: Data were collected over 3 months through in depth interview with 6 new nurses who had worked less than 1 year in a newly established ICU of university hospital of less than 1 year located in Y city. The Colaizzi analysis method was used for data analysis. Results: The themes were classified into 13 themes clusters. The 13 themes clusters were finally grouped into 6 categories, ‘The endlessness of a new beginning’, ‘Pressure of work due to lack of senior nurses’, ‘Wanting to quit’, ‘Attachment for the complete hospital and ICU’, ‘Preciousness of colleagues’, ‘Pride in self-growth’. Conclusion: New ICU nurses have a difficult time due to pressures of work and lack of expert knowledge, and anxiety adds to these problems making the situation more difficult. The study results indicate that professional knowledge and skills learned through repetition of difficult work, pride through self growth, recognition from others and good-fellowship are driving forces to overcome obstacles and with stand difficult daily work.

Purpose: The purpose of this study was to identify the relationship between emotional intelligence and stress coping of nurses in hospitals. Method: The study was a descriptive-correlational study with a convenience sample of 298 nurses. Descriptive statistics t-test, Mann-Whitney U, One-way ANOVA and Pearson correlation coefficients were used for data analysis. Results: The results of this study were as follows; Emotional intelligence was higher in married nurses than unmarried nurses (t=-2.90, p=.004). Nurses with a clinical career of 4~7 years had better stress coping than nurses with shorter careers (F=5.60, p=.004). Ward nurses better stress coping than nurses in emergency rooms and Intensive care units (F=4.43, p=.013). Fixed shift nurses had better stress coping than nurses on rotation shifts (t=-2.37, p=.019). There was a significant positive correlation between emotional intelligence and stress coping(r=.29, p<.001). Conclusion: The results indicate that stress coping is better in nurses with higher emotional intelligence, 4~7 year clinical experience, working on ward a as well as having a fixed shift. However further development and application of programs which can improve nurses" emotional intelligence are needed.
