  • 본 연구에서는 인위적 수공시설물을 고려하지 않는 자연상태의 가뭄해석을 위해 자연가뭄지수(NDI)를 산정하고 활용성을 평가하였다. 자연가뭄지수는 주성분 분석을 이용하여 산정하였으며, 입력자료는 3개월 누적강수량, 자연유량, 토양수분량 자료이다. 강수량은 ASOS 59개 지점 자료이고, 자연유량 및 토양수분량은 지표수문해석모형의 결과를 이용하였다. 가뭄지수의 평가기간은 1977~2012년이며, 활용성 평가를 위해 시계열 분석, 지역별 분석 및 가뭄특성인자 분석을 수행하였다. 시계열 분석결과, 자연가뭄지수는 가뭄의 시작과 끝에 대한 평균절대오차는 0.85로 가장 정확하게 나타났다. 과거 가뭄사례와 가뭄특성인자를 분석한 결과, 자연가뭄지수의 지속기간과 발생간격의 평균절대오차는 각각 1.3, 1.0으로 가뭄의 지속기간 및 발생간격을 적절히 반영하는 것을 확인하였다. 지역별 분석결과, 자연가뭄지수는 단일변량 가뭄지수의 지역별 가뭄상황을 적절히 반영하여 활용성이 높은 것으로 나타났다. 또한, 가뭄의 시작, 끝, 지속기간, 발생간격에 대한 자연가뭄지수, 표준강수지수, 표준유출지수, 표준토양수분지수의 순위를 분석한 결과 자연가뭄지수가 가장 높은 순위로 산정되었다. 자연가뭄지수는 기존 단일변량 가뭄지수의 상이한 가뭄상황을 종합적으로 반영하며, 가뭄의 특성을 정량적으로 제시한다는 점에서 활용성이 높다고 판단된다.

  • 신성 요붕증은 항이뇨호르몬의 정상적 분비에도 불구하고, 신장의 집합관의 항이뇨호르몬에 대한 반응이 저하되어 요농축능에 이상이 초래되는 질환이다. 특히 선천성 신성 요붕증은 대게 반성 열성 유전 양식을 따르는 유전 질환으로 매우 드물어 소아에서는 간헐적 보고만 있어 왔다. 어린 소아에서는 증상이 비특이적일 수 있고, 임상적 진단도 쉽지 않은데, 최근에는 항이뇨 호르몬 수용체 유전자의 돌연변이들이 확인되어 유전자 검사로 확진이 가능하게 되었다. 기존의 보고들은 선천성 신성 요붕증이 진단된 환아들에 대한 이뇨제나 비스테로이드성 항염증제 등을 포함한 치료가 이루어진 증례보고이었으나 이들의 치료 후 장기적 추적 결과 보고가 극히 드물며, 이들 약제에 의한 치료 효과는 낮은 것으로 알려져 있다. 저자들은 극심한 이뇨로 인한 이차적 요로기관의 변형이 초래되었던 8세 소아에서 환아와 엄마의 말초 혈액 유전자 분석 검사상 Xq28 염색체 부위의 AVPR2 유전자의 돌연변이가 확인되었고 hydrochlorothiazide, indomethacin 및 amiloride 병합 치료 후 배뇨량은 하루 12리터에서 4리터로 감소하였고, 성장 발육도 정상이었으나 더 이상의 호전이 없고 일상 생활에 불편함이 지속되어 보조적 방광루 형성술을 시행받은 후, 증상 호전 및 심리적 안정을 얻었던 심한 선천성 신성 요붕증 1례의 5년간의 추적 관찰 결과를 보고하는 바이다.

  • Objectives : The purpose of this study was to analysis the relationship between hours of smartphone use and neck pain in university students. Methods : A survey of 2,353 university students was conducted in Gyeonggi province and Incheon city using a self report questionnaire from April 1 to 11 2013. The questionnaire of questions regarding the hours of using smartphone, mainly used function in participant's smartphone and neck discomfort degree. Neck disability index(NDI) was used to evaluate degree of pain. The collected data were analyzed with the t-test and Kendall's tau test using the SPSS 21.0 program and R 3.1.0, respectively. Results : 1. Almost all of the survey participants(99.07 %) were smartphone users. 66.97 % of them answered that they use their smartphone daily more than 2 hours and 48.18 % of them answered that they use their smartphone 10 to 30 minutes everytime they use it. 2. The overall distribution of NDI scores was 'no disability(0~4 score, 62.92 %)', 'mild disability(5~14 score, 32.85 %)', 'moderate disability(15~24 score, 1.19 %)'. As a result of t-test, we found that the average NDI score for female students was significantly higher than the average NDI score for male students(p<0.05). 3. The Kendall's tau test revealed that total time spent daily using smartphones has a strong positive correlation with 'pain intensity', 'lifting', 'reading' 'headache', 'concentration', and 'driving'(p<0.05) in NDI. Also, time duration of one time smartphone usage has a strong positive correlation with 'pain intensity', 'lifting', 'reading', 'headache', 'concentration', 'work', and 'recreation'(p<0.05). 4. The Kendall's tau test revealed that total NDI scores have a significantly strong positive correlation with both of total time spent daily using smartphones(p<0.05) and time duration for one time smartphone usage(p<0.05). This results imply that long-time use of smartphone has a strong relationship with neck pain. Conclusions : The results of the study would be a good starting point for future studies to reduce the risks of chronic neck pain caused by smartphone usage.

  • Objective: Several muscles surrounding neck are vital not only for neck motion, but for upper extremities motions as well. Neck pain would affect neck and shoulder disability. The Neck Disability Index (NDI), Shoulder Pain and Disability Index (SPADI), and Visual Analogue Scale (VAS) are increasingly used to evaluate treatment effectiveness after chronic neck pain. The purpose of this study was to analyze the correlation of neck pain, shoulder pain, and quality of life in patients with chronic neck pain. Design: Cross-sectional study. Methods: Forty-three patients with neck pain participated in this study. Participants were instructed to place a mark on each item of three clinical measures that best represented their experience of his/her neck and shoulder problem over the last week. The outcome measures of the study were NDI, SPADI, and VAS for neck and shoulder pain and disability. Results: The NDI was significantly correlated with the VAS-Neck, SPADI-Pain, SPADI-Disability, SPADI-Total, and VAS-Shoulder (p<0.05). The VAS-Neck was significantly correlated with the VAS-Neck, SPADI-Pain, SPADI-Disability, SPADI-Total, and VAS-Shoulder (p<0.05). The SPADI-Total was significantly correlated with the NDI, VAS-Neck, SPADI-Pain, SPADI-Disability, and VAS-Shoulder (p<0.05). The SPADI-Pain was significantly correlated with the NDI, VAS-Neck, SPADI-Disability, SPADI-Total, and VAS-Shoulder (p<0.05). The SPADI-Disability was significantly correlated with the NDI, VAS-Neck, SPADI-Total, SPADI-Pain, and VAS-Shoulder (p<0.05). The VAS-Shoulder was significantly correlated with the NDI, VAS-Neck, SPADI-Pain, SPADI-Disability, and SPADI-Total (p<0.05). Conclusions: Neck disability in patients with chronic neck pain should be considered with disability and pain of the shoulder.

  • Objectives This study was aimed at comparing clinical effectiveness among trigger point treatment, Self-exercise treatment, trigger point - self-exercise cooperative treatment for neck pain caused by traffic accidents. Methods 63 patients with neck pain by traffic accidents were divided into 3 groups. Different types of treatments were carried out for each groups ; group A with trigger point, group B with self-exercise, group C with trigger point and self-exercise cooperative treatment. 3 groups were also treated with general acupuncture and herb-medicine treatment. Pain threshold, visual analogue scale (VAS), and neck disability index (NDI) were checked on a daily basis. SPSS ver. 18.0 for Windows was used for analysis of data. The effectiveness of treatment of each groups were verified by using paired test and one-way repeated-measures ANOVA test, and the comparison of VAS, NDI and pain threshold were demonstrated by independent samples t-test. Results 3 groups all showed significant difference in pain threshold, VAS and NDI after 8 days later. Group C showed more improvement in pain threshold, VAS and NDI than shown in group A and B. In the first period (from pre-treatment to 4th day treatment) group C showed significant difference in NDI and pain threshold but not in VAS as compared to group A and B. In the second period (from 4th treatment to 8th day treatment), Group C showed significant difference in pain threshold, VAS and NDI as compared to group A and B. Conclusions Trigger point - self-exercise cooperative treatment is proved to be more helpful to improve the unstability and reduce neck pain than trigger point treatment or self-exercise treatment only, therefore eventually leading to better satisfaction for patients with neck pain.

  • Objective: The aim of this study was to find a correlation between the Nepean Dyspepsia Index (NDI) and electrogastrography (EGG) in clinical practice students. Methods: In total, 28 students were enrolled. NDI and EGG were measured in all students. NDI was classified as abnormal when the score was 11 or more. In EGG, standard 1 was classified as abnormal if the preprandial or postprandial percentage of normal gastric slow waves of Ch3 was less than 70% or if power ratio of Ch3 was less than 1. Standard 2 was classified as abnormal if standard 1 was met or if the percentage of normal gastric slow waves of Ch3 decreased after meals. Results: NDI and EGG had no statistically meaningful correlation when standard 1 was used, but NDI and EGG had statistically meaningful correlation when standard 2 was used. Conclusions: These findings suggest that NDI and EGG are correlated and that EGG can be used to evaluate the degree of dyspepsia.

  • Purpose: The purpose of this study was to investigate the effects of neck patterns in proprioceptive neuromuscular facilitation (PNF) for neck movement and the neck disability index (NDI) among adults with forward head posture. Methods: Thirty-nine subjects were randomly assigned into two groups. Subjects in the proprioceptive neuromuscular facilitation exercise group (PNFG, n = 20) received 20 minutes of PNF neck pattern (flexion-Rt. lateral flexion-Rt. rotation followed by extension-Lt. lateral flexion-Lt. rotation) 3 times weekly for 4 weeks. Outcomes were measured using absolute rotation angle (ARA), anterior weight bearing (AWB), range of flexion and extension motions (RFEM), and neck disability index (NDI) methods before and after the 4-week intervention period. Results: There were significant effects for the PNFG, pre- and post-intervention, in ARA, AWB, RFEM, and NDI. There were significant differences in ARA, AWB, RFEM, and NDI compared with CG. Conclusion: The results of this study suggest the PNF neck pattern could be beneficial for adults with forward head posture.

  • Purpose : This study aimed to evaluate the effects of sitting questionmark exercise (SQE) and brugger's relief exercise (BRE) on pain, ROM, proprioception, NDI in 60 Patients with Chronic Cervical Pain (CCP). Methods : In this study the VAS and NDI were used to investigate changes in pain and disability with SQE and BRE. The pre and post intervention intra group differences were analysed with a paired t-test for mean values, and the inter group differences were analyzed with an independent t-test for mean values. Results : The pain of both of groups was lowered with statistical significance. Pain of SQE group is lower than that of BRE group with statistical significance. ROM in both groups was improved, but there is no significant difference between two groups. NDI in both of groups were significantly decreased after the intervention, but there was no significant difference between groups. there was NDI ratio (%) significant difference between each groups. Conclusion : SQE intervention may be considered a more effective clinical approach for reducing pain and restoring proprioception in patients with CCP.
