조민경,박두흠,유재학,유승호,하지현,Cho, Min-Kyung,Park, Doo-Heum,Yu, Jaehak,Ryu, Seung-Ho,Ha, Ji-Hyeon 대한수면의학회 2014 수면·정신생리 Vol.21 No.2
목 적 : 본 연구는 불안장애 환자를 대상으로 안정 시와 기립 시기, 정신적 스트레스 시기에 심박변이도 지수(heart rate variability index, HRV index) 검사를 시행하여 자율신경계 불균형이 육체적 및 정신적 스트레스에서 어떻게 변화되는지 알아보고자 하였다. 방 법 : 불안장애 환자 60명을 대상으로 연구를 수행하였다. 안정 시기, 기립 시기, 정신적 스트레스 자극을 준 시기 동안 각각 심박변이도 지수를 측정하였다. 긴장 정도와 스트레스 정도에 대해 visual analogue scale (VAS) score로 측정하였고, Beck depression inventory (BDI), state trait anxiety inventory-I, II (STAI-I, II)를 사용하여 불안증상과 우울증상의 심각도를 평가하였다. 통계적 검증은 안정 시기와 기립 시기, 안정 시기와 정신적 스트레스 시기 간의 각각의 자율신경계 관련 지수 변화를 보기 위해 paired t-test로 분석하였고, 성별 차이를 보기 위해 ANCOVA로 비교 분석하였다. 결 과 : 안정 시기와 비교하여 기립 시기에서 SDNN, LF/HF의 유의한 증가(p < 0.01) 및 NN50, pNN50, normalized HF(nHF)의 유의한 감소를 보였다(p < 0.01). 안정 시기와 비교하여 스트레스 시기에서 SDNN, RMSSD, LF/HF의 유의한 증가를 보였고(p < 0.01), nHF의 유의한 감소가 있었다(p < 0.01). 기립 시기와 비교하여 스트레스 시기에 SDNN, NN50, pNN50, HF지수가 유의하게 높은 결과를 보였다. 결 론 : 두 스트레스 모두에서 안정 시기와 비교하여 자율신경계의 균형을 나타내는 LF/HF ratio의 유의한 상승을 보였고, 두 스트레스 간 LF/HF ratio의 유의한 차이는 없었다. 두 스트레스 간에 SDNN, NN50, pNN50은 유의한 차이를 보이나, nVLF, nLF, nHF, LF/HF ratio에서는 유의한 차이가 없어 시간 영역 보다 주파수 영역의 지수가 두 스트레스의 비교에 좀더 특이도가 높다고 생각된다. Objectives: This study was designed to assess the change of heart rate variability (HRV) at resting, upright, and psychological stress in anxiety disorder patients. Methods: HRV was measured at resting, upright, and psychological stress states in 60 anxiety disorder patients. We used visual analogue scale (VAS) score to assess tension and stress severity. Beck depression inventory (BDI) and state trait anxiety inventories I and II (STAI-I and II) were used to assess depression and anxiety severity. Differences between HRV indices were evaluated using paired t-tests. Gender difference analysis was accomplished with ANCOVA. Results: SDNN (Standard deviation of normal RR intervals) and low frequency/high frequency (LF/HF) were significantly increased, while NN50, pNN50, and normalized HF (nHF) were significantly decreased in the upright position compared to resting state (p < 0.01). SDNN, root mean square of the differences of successive normal to normal intervals, and LF/HF were significantly increased, while nHF was significantly decreased in the psychological stress state compared to resting state (p < 0.01). SDNN, NN50, pNN50 were significantly lower in upright position compared to psychological stress and nVLF, nLF, nHF, and LF/HF showed no significant differences between them. Conclusion: The LF/HF ratio was significantly increased after both physical and psychological stress in anxiety disorder, but did not show a significant difference between these two stresses. Significant differences of SDNN, NN50, and pNN50 without any differences of nVLF, nLF, nHF, and LF/HF between two stresses might suggest that frequency domain analysis is more specific than time domain analysis.

Purpose: Laparoscopic surgery for left-sided colon cancer is one of the most frequent procedures performed in laparoscopic colorectal surgery. In this study, we analyzed clinical and long-term oncological outcomes of left-sided colon cancer patients who underwent conventional laparoscopic surgery (CLS) and hand-assisted laparoscopic surgery (HALS). Methods: A total of 172 CLS patients and 72 HALS patients for left-sided colon cancer from July 2001 to December 2011 were included in this study. The collected data included the clinical and oncological outcomes. We analyzed overall survival and disease-free survival by tumor, node, metastasis (TNM) stage. Results: The mean age of the patients was 64 years, and male patients were predominant. The mean follow-up period was 58.1 months. The number of patients that belong in each TNM stage 0, I, II, III, and IV was as follows: 17 (7%), 47 (19.2%), 70 (28.7%), 80 (32.8%), and 30 (12.3%), respectively. Overall 5-year survival rate for TNM stage I, II, III, and IV was 87.1%, 82.8%, 82%, and 12%, respectively. Overall 5-year survival rate for CLS group and HALS group was 90.2% and 66.7%, 86.5% and 77%, 88.7% and 67.4%, and 18.9% and 0%, respectively. Disease-free 5-year survival rate for TNM stage I, II, and III was 97.7%, 90.7%, and 72.8%, respectively. Disease-free 5-year survival rate for CLS group and HALS group was 97.3% and 100%, 100% and 78.8%, and 81% and 55.1%, respectively. Conclusion: These data show the feasibility and safety of laparoscopic surgery for left-sided colon cancer in terms of long-term oncological outcomes.
한국 다문화사회에 있어서 이주민의 이중문화 정체성과 사회문화적응의 관계

본 연구는 한국사회의 일원으로 자리를 잡고 있는 이주민들의 ``이중문화 정체성``이 한국의 ``사회문화적 적응``에 어떠한 영향을 미치는가를 살펴보고, 이러한 영향관계에 조절적인 효과를 미치는 변수들이 무엇인가를 파악해 보고자 한다. 실증 분석을 위해 Martinez & Haritatos의 BII Scale과 Ward & Kennedy의 SSQ로 구성한 설문지를 이용하여, 경상북도와 대구광역시에 거주하고 있는 결혼이주여성과 이주노동자 160명을 방문·조사를 실시하였다. 분석 결과, 이중문화 정체성 수준이 사회문화적 적응에 통계적으로 유의미한 긍정적인 영향을 미치며, 성별과 거주기간 등이 이러한 영향관계에 조절적인 효과를 보이고 있는 것으로 나타났다. During the last two decades, the Korean society has experienced the significant increase of international immigrants, which takes over 1 percent of the total population of 2010 in Korea. The influx of international immigrants requires not only individual adaptation but also various social and cultural changes in dealing with their settlements in Korea. Since international immigrants are considered to be bicultural in terms of their ethnic cultures, this study focuses on the relationship between their bicultural identity and sociocultural adaptation. More specifically, we empirically investigate how bicultural immigrants, who vary in extent to which they feel bicultural conflict and distance, show different levels of sociocultural adaptation in Korea. The study used Martinez & Haritatos` Bicultural Identity Integration Scale, which consisted of 8 items measuring bicultural conflict and distance, and Ward & Kennedy`s Social Situations Questionnaire, which is a modified version of Furnham & Bochner`s scale and consisted of 41 items measuring the level of sociocultural adaptation. A total of 160 international immigrants living in Korea (74 immigrant brides and 86 immigrant workers) participated in this study. Based on our survey analyses, the study found that the relationship between bicultural identity and sociocultural adaptation was significantly negative (p<.001). This result shows that the conflict and distance between origin culture and mainstream culture have a negative impact on the level of sociocultural adaptation. In addition, results confirm mediational role of gender and the length of residence on the impact of bicultural identity on sociocultural adaptation.
