Objectives : The purpose of this study is to investigate the relationship between the triallelic serotonin transporter gene and stressful life events to determine their effect on depression with alcohol dependence. Methods : Ninety-five hospitalized patients with alcohol dependence (73 male, 22 female) were enrolled in this study. Thirty-two (33.7%) of the total patients were diagnosed with major depressive disorder and dysthymic disorder by Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders-IV. The characteristics of stress were evaluated using the stressful life events scale, and depressive symptoms were assessed using the depression scale (Beck Depression Inventory, BDI). Alcoholism with depression (n = 32) and alcoholism without depression (n = 63) were genotyped for the triallelic serotonin transporter gene ($L_A$ : higher expressing allele, $L_G$/S : lower expressing allele). Results : There was no significant difference in the allele frequency between the depression group and the non-depression group (${\chi}^2$ = 0.345, p = 0.619). $L_G$/S alleles had more comorbid depression in the higher score of stressful life events scale [Mental-Haenszel (MH)-${\chi}^2$ = 4.477, p = 0.034]. But there was no significant difference in the comorbidity according to the scores from the stressful life event scale in the $L_A$ alleles (MH-${\chi}^2$ = 0.741, p = 0.399). In the results, alcohol-dependent individuals with $L_G$/S alleles had more comorbid depression than those with $L_A$ alleles when they had experienced severe stressful life events (MH-odds ratio = 2.699, p = 0.028). Conclusions : These results suggest that there is no direct relationship between triallelic serotonin transporter gene and depression in the alcohol dependent patients. But alcohol dependent individuals with the lower expressing alleles of the serotonin transporter gene were more susceptible to depression than those with the higher expressing alleles in response to stressful life events.

Purpose: Flexed posture commonly increases with age in older women and is characterized by an excessive curvature in the thoracic spine (kyphosis), forward head posture, and decline in height. This study was conducted in order to determine the relationship between flexed posture, physical performance, and psychosocial factors in community dwelling elderly women in Korea. Methods: Fifty-two subjects with thoracic kyphosis of $40^{\circ}C$ or greater participated in this study. Flexed posture was measured using kyphosis angle (KA), forward head posture (FHP), and round shoulder (RS), and physical performance was evaluated using the short physical performance battery (SPPB), grip strength, and static and dynamic balance. Psychosocial factors were measured using depression and the quality of life (QOL). All data were analyzed using SPSS 18.0 software for windows. Results: KA showed significant correlation with SPPB score (r=-0.447) and dynamic balance (r=0.426) (p<0.05) depression (r=0.405) and QOL (r=-0.464) but not with grip strength and static balance in elderly individuals. FHP and RS showed significant correlation with SPPB score (r=0.002, r=-0341) and dynamic balance (r=-0.278, r=0.346) (p<0.05) but not with psychosocial factors. Conclusion: These findings suggest that flexed posture provides meaningful information about physical performance and psychosocial factors in elderly women. Our data suggest that the flexed posture may need to be addressed as part of the health management process for elderly women.

The objectives of this study were to investigate the quality characteristics of Jeungpyun added with goji berry powder (0, 2, 4, 6%) and to develop functional Jeungpyun as snack for the elderly. The volume of batter without goji berry powder increased 2.9 times after 4 hrs of fermentation, whereas those with 2, 4, and 6% goji berry powder increased 1.8~1.9 times. The pH and brix of the batter increased by increasing the concentration of goji berry powder. The expansion volume of Jeungpyun decreased by increasing the concentration of goji berry powder. The pH of Jeungpyun was higher than that of Jeungpyun batter in all groups. However, the brix of Jeungpyun was lower than that of Jeungpyun batter in all groups. The L value of Jeungpyun decreased, whereas a and b values increased by increasing the concentration of goji berry powder. The consumer acceptability score was higher in the elderly than in university students. Jeungpyun with 4% goji berry powder had best ratings in taste and overall preference. The DPPH free radical scavenging antioxidant activity of Jeungpyun significantly increased with increasing concentration of goji berry powder. Therefore, goji berry Jeungpyun is available as a snack for the elderly and can be added to goji berry powder up to 4%.

본 논문은 탄약, 미사일, 우주발사체 등과 같은 일회성(one-shot) 시스템의 가부반응데이터를 이용하여 신뢰도를 추정하는 새로운 방법을 제안한다. 제안한 방법은 모수 추정법을 기반으로 한다. 제안한 방법은 가부반응 데이터의 시간에 따른 고장 비율 감소를 고려하였으며 모수 추정법의 문제점을 극복할 수 있다. 기존 문헌에 공개된 7 가지 추정방법들과 제안한 방법과의 정확성을 비교하여 제안한 방법을 검증하였다. 정확성 비교 시, 다양한 샘플 수 변화를 고려하여 신뢰도 추정결과에 대한 SSE 를 이용하였다. 정확성 비교 결과, 제안한 방법은 다른 방법에 비해 정확성이 높은 신뢰도 추정결과를 제공하였다. This paper proposes a new reliability estimation method for one-shot systems using quantal response data, which is based on a parametric estimation method. The proposed method considers the time-variant failure ratio of the quantal response data and it can overcome the problems in parametric estimation methods. Seven reliability estimation methods in the literature were compared with the proposed method in terms of the accuracy of reliability estimation in order to verify the proposed method. To compare the accuracy of reliability estimation, the SSEs (Sum of Squared Error) of the reliability estimation results for the different estimation methods were evaluated according to the various numbers of samples tested. The proposed method provided more accurate reliability estimation results than any of the other methods from the results of the accuracy comparison.

장현정(Jang, Hyun-Jeong),김선엽(Kim, Sun-Youb),전재국(Jeon, Jae-Guk),신의주(Shin, Eui-Ju) 한국산학기술학회 2013 한국산학기술학회논문지 Vol.14 No.6

본 연구는 비특이성 경부통 환자의 경부통증수준과 상지 기능장애간에 상관성을 알아보고자 실시하였다. 경 부통증과 경부기능장애는 Northwick Park Neck Pain Questionnaire(NPQ)로 상지 기능장애는 상지기능장애 설문지 (disabilities of arm, shoulder, hand questionnaire; DASH)를 이용하여 평가하였다. 잠재적인 교란변수로 작용할 수 있 는 심리학적 변수는 통증 자아효능감(Pain Self Efficacy; PES)과 공포회피반응 설문지(fear-avoidence beliefs questionnaire; FABQ)를 이용하여 측정하였다. 분석 결과, NPQ 점수와 DASH 점수는 피어슨 상관 계수가 0.628점의 양의 상관관계가 있었으며, PES과 FABQ 점수와도 유의한 상관성을 나타내었다. 이 결과를 통해 경부통 환자의 경 부통 및 경부기능장애 수준과 상지 기능장애 수준 간에 상관성이 나타날 수 있음을 알 수 있었다. 또한 통증에 대한 부정적인 인식과 공포회피반응이 심한 환자의 경우 상지 기능평가에 직접적인 영향을 줄 수 있는 것으로 확인되었 다. 이에 경부통 환자의 관리 시 상지 기능장애와 심리학적 요인을 평가하여야만 할 것이다. The purpose of this study was to investigate the relationship between neck pain and upper limb disability in patients with non-specific neck pain (n=132) recruited from physiotherapy departments in the Korea. Baseline neck pain/disability was measured using the Northwick Park Neck Pain Questionnaire (NPQ) and upper limb disability was measured using the Disabilities of Arm, Shoulder, Hand questionnaire (DASH). A range of baseline psychosocial variables were measured as potential confounding variables. Pairwise analysis revealed a positive correlation between NPQ score and DASH score (Pearsons’ r=0.628, p<0.05). This study provides preliminary evidence that patients with severe neck pain/disability also report severe upper limb disability. The presence of severe neck pain or low pain self efficacy and high fear-avoidence beliefs questionnaire should clinicians towards a careful examination of upper limb function in patients presenting with neck pain. Our data suggest the upper limb disability may need to be addressed as part of the neck management process.
