PURPOSE: The aim of this study is to find a more efficient intervention method through a study of the gait variables and dynamic balance of chronic neck pain patients. METHODS: Forty subjects aged between 40 and 60 years were allocated randomly to two groups; The first group performed PA (Posteroanterior Mobilization), and the second group conducted CCF (Craniocervical Flexion Exercise). The gait variability measured the speed, cadence, and dynamic balance in the forward, leftward, rightward, and rearward directions. An independent t-test, Wilcoxon signed-rank test, and paired t-test were used for statistical analysis. RESULTS: In the dynamic balance measurements, the variability of PA (p < .000) and CCF (p < .000) in the rightward direction, PA (p < .004) in leftward direction and forward direction increased significantly (p < .013). In an analysis of the gait variability, the cadence increased significantly in the PA group (p < .022) and not significantly in the CCF group (p < .056). On the other hand, there was no increase in the speed variable, in the PA group (p < .437). In the CCF group, the cadence increased significantly (p < .022). The differences in the PA and CCF group differences were not significant. CONCLUSION: The PA group showed a significant increase in the forward (p < .013), leftward (p < .004), and rightward directions (p < .000). Speed was significant in the CCF group, and cadence was significant in the PA group. The dynamic Balance was effective in the rightward direction in both groups, but there was no significant difference between the two groups.

자율주행기술은 4차 산업혁명을 대표하는 기술로 주목되고 있음에 따라 자율주행차 지원을 위한 정밀도로지도 구축에 많은 투자가 이루어지고 있다. 현재 정밀도로지도는 지상 mobile mapping systems(MMS) 측량을 통해 구축되고 있지만, 장비 및 비용·효율의 한계가 존재한다. 이 연구는 정밀도로지도 구축에 있어 항공사진을 이용하여 구축된 정밀도로지도 분석을 통해 정밀도로지도 구축 가능성을 검토하였다. 검토 결과 지상표본거리 12cm 항공사진을 이용할 경우 지상표본거리 25cm 항공사진보다 구축 가능한 레이어 유형의 범위가 넓었으며, 지상표본거리 12cm 항공사진을 통해 구축된 정밀도로지도의 정밀도를 분석한 결과 평면오차는 0.15m, 수직오차는 0.20m 이내로 확인되었다. 이는 국토지리정보원의 정밀도로지도 품질검사 기준인 벡터데이터 절대정확도 0.25m를 모두 만족하는 수치로 나타났다. 레이어 구축범위 및 정밀도 분석결과를 고려해볼 때 정밀도로지도 구축 시 지상 MMS 측량 외 항공사진측량을 필요에 따라 활용할 경우 MMS장비 한계의 보완과 효율적인 정밀도로지도 제작·갱신이 가능할 것으로 기대된다. As autonomous driving technology is attracting attention as part of the 4th industrial revolution, significant investment is being made in developing high definition road maps to support autonomous vehicles. Currently, high definition road maps are being developed through land-based Mobile Mapping Systems surveying, but there are limitations in terms of equipment, cost, and efficiency. This study examined the possibility of developing a high definition road map through aerial photogrammetry rather than via existing methods. As a result, when using aerial photographs with a Ground Sampling Distance(GSD) of 12 cm, the range of layer types that can be constructed was wider than that of a 25 cm GSD aerial photograph. As a result, the HDmap developed through aerial photogrammetry with the 12 cm GSD contributed to plane and vertical errors of 0.15 m and 0.20 m, respectively. These values satisfy a vector data absolute accuracy of 0.25 m, which is the inspection standard for high definition road map quality defined by the National Geographic Information Institute. Considering the range of layers that can be constructed and the results of precision analysis, it is possible to supplement equipment limitations, and create and update an efficient high definition road map using aerial photogrammetry in addition to land-based MMS surveying.

본 연구는 주정중독에 동반된 우울증 환자의 치료에서 적어도 행동학적 부작용의 관점에서는 PAR이 AMI보다 우수함을 증명하였다. 이러한 PAR의 행동학적 효과의 우수성은 환자의 삶의 질을 향상시키고 결국 치료결과를 높이는데 관여하리라고 생각된다. Objective : It has been proposed that cognition and related aspects of mental functioning are decreased in depression as well as in alcoholism. The objective of the study was to compare behavioral side effects of paroxetine and amitriptyline in depressed patients accompanied by alcoholism. The focused comparisons were drug effects concerning psychomotor performance, cognitive function, sleep and daytime sleepiness during the first 2 weeks of treatment. Methods : After an alcohol detoxification period(3 weeks) and a washout period(1 week), a total of 20 male inpatients with alcohol use disorder (DSM-IV), who also had a major depressive episode(DSM-IV), were treated double-blind with paroxetine 20mg/day(n=10) or amitriptyline 25mg/day(n=10) for 2 weeks. All patients were required to have a scare of at least 18 respectively on bath the Hamilton Rating Scale far Depression(HAM-D) and Beck Depression Inventory(BDI) at pre-drug baseline. Patients randomized to paroxetine received active medication in the morning and placebo in the evening whereas those randomized to amitriptyline received active medication in the evening and placebo in the morning. All patients performed the various tasks in a test battery at baseline and at days 3, 7 and 14. The test battery included : critical flicker fusion threshold for sensory information processing capacity : choice reaction time for gross psychomotor performance : tracking accuracy and latency of response to peripheral stimulus as a measure of line sensorimotor co-ordination and divided attention : digit symbol substitution as a measure of sustained attention and concentration. To rate perceived sleep and daytime sleepiness, 10cm line Visual analogue scales were employed at baseline and at days 3, 7 and 14. The subjective rating scales were adapted far this study from Leeds sleep Evaluation Questionnaire and Epworth Sleepiness Scale. In addition a comprehensive side effect assessment, using the UKU side effect rating scale, was carried out at baseline and at days 7 and 14. The efficacy of treatment was evaluated using HAM-D, BDI and clinical global impression far severity and improvement at days 7 and 14. Results : The pattern of results indicated thai paroxetine improved performance an mast of the lest variables and also improved sleep with no effect on daytime sleepiness aver the study period. In contrast, amitriptyline produced disruption of performance on same tests and improved sleep with increased daytime sleepiness in particular at day 3. On the UKU side effect rating scale, mare side effects were registered an amitriptyline. The therapeutic efficacy was observed in favor of paroxetine early in day 7. Conclusion : These results demonstrated thai paroxetine in much better than amitriptyline for the treatment of depressed patients accompained by alcoholism at least in terms of behavioral safety and tolerability, furthermore the results may assist in explaining the therapeutic outcome of paroxetine. For example, and earlier onset of antidepressant action of paroxetine may be caused by early improved cognitive function or by contributing to good compliance with treatment.

문옥곤(Ok-Kon Moon),최태석(Tae-Seok Choi),최완석(Wan-Seok Choi) 한국엔터테인먼트산업학회 2020 한국엔터테인먼트산업학회논문지 Vol.14 No.8

본 연구의 목적은 40~50대 중년에서 두개척추각(CVA), 나이, BMI와의 상관관계를 알아보는 것이다. 신체 건강한 성인 남녀 40~50대 456명을 대상으로 3D 센서를 활용한 자세측정기를 활용하여 전방머리 자세를 측정하였다. 연구결과 전체 중년의 CVA는 나이와는 높은 수준의 음의 상관관계가 있고((r=-.937; p<.01), BMI에 대해서는 매우 낮은 수준의 양의 상관관계(r=.056가 있음을 확인하였다. 성별에 따른 연구 에서 중년 남성의 CVA는 나이와는 높은 수준의 음의 상관관계가 있었고(r=-.932; p<.01). BMI에 대해서는 매우 낮은 수준의 양의 상관관계(r=.071)가 있었다. 반면 중년 여성의 경우엔 나이에 대해서만 높은 수준의 음의 상관관계(r=.940, p<.01)가 나타났고 BMI에 대해서는 상관관계가 나타나지 않았다. 본 연구는 CVA가 남성과 여성 모두에서 연령과 유의 한 음의 상관관계를 가지고 있지만, BMI와 낮은 수준의 상관관계를 가지고 있음을 시사한다. The purpose of this study was to investigate the correlation between craniovertebral angle(CVA), age, and body mass index(BMI) in middle-aged people in their 40s and 50s. The forward head posture(FHP) was measured using a posture measuring device using a 3D sensor for 456 healthy men and women. As a result of the study, the middle-aged CVA had a high level of negative correlation with age (r=-.937; p<.01) and a very low level of positive correlation with BMI (r=.071). CVA of middle-aged men had a high negative correlation with age (r=-.932; p<.01) and a very low positive correlation with BMI. There was a correlation (r=.056), whereas, for middle-aged women, there was a high level of negative correlation (r=.939, p<.01) only with age, but had a weak (low level of negative) correlation with BMI. This study suggests that CVA has a significant negative correlation with age in both males and females however, has a weak relationship with BMI.

PURPOSE: To investigate the correlation between sleep quality, neck and shoulder pain, neck and shoulder disability, headache, and smartphone addiction in adults, as well as factors affecting sleep disorders in adults. METHODS: A total of 112 adults in their 20s were recruited for participation in this study. This study measured Pearson’s correlation of sleep quality, neck and shoulder pain, neck and shoulder disability, headache and smartphone addiction. Logistic regression analysis (sleep disorder, without sleep disorder adults), was performed to analyze factors affecting sleep disorders. RESULTS: Sleep quality index was positively correlated with shoulder pain and disability index(SPADI)-pain score, SPADI-global score and smartphone addiction score. There was a significant difference in SPADI-pain score between the group with sleep disorders and the group without sleep disorders. Shoulder pain and disability were identified as factors affecting sleep disorders. The group with sleep disorders showed 1.088 times more shoulder pain than the group without sleep disorders, and the group with sleep disorders showed 1.006 times higher frequency of shoulder disorders than the group without sleep disorders. CONCLUSION: The results of the present study indicate that as sleep quality worsens, shoulder pain , disability, and smartphone addiction get worse. The group with sleep disorders had significantly increased shoulder pain compared to the group without sleep disorders. We also found that shoulder pain and disability were factors affecting sleep quality. Comparison between intervention method is warranted to better understand adults with sleep disorders.

This survey was conducted to evaluate the microbial contamination level of butcher`s shops in Seoul, Korea. For microbial inspections, a total of 584 samples (146 cotton work gloves, 146 utensils and equipments, 154 beef samples, 138 pork samples) were collected from butcher`s shops. E. coli and pathogenic bacteria such as Staphylococcus aureus, Yersinia enterocolitica, Listeria monocytogenes, Salmonella spp., and E. coli O157:H7 were tested in the samples. As a result, the level of aerobic plate count (APC) ranged ≤104 CFU/cm2 from utensils and equipments, 101∼109 CFU/glove from cotton work gloves and ≤106 CFU/g from meat. The APC level of E. coli ranged ≤101 CFU/cm2 from utensils and equipments, ≤105 CFU/glove from cotton work gloves, and ≤103 CFU/g from meat, respectively. Staphylococcus aureus was detected in 2 beef samples, 1 pork sample, and 10 used cotton work gloves. Yersinia enterocolitica was detected in 3 beef samples, 1 pork sample, and 3 used cotton work gloves. Listeria monocytogenes was detected in 2 used cotton work gloves. In order to improve the sanitation status of butcher`s shops, application of HACCP (Hazard Analysis Critical Control Point) or SSOP (Sanitation Standard Operating Procedure), regular hygiene education, and continuous monitoring for microorganisms will be required.
