선박은 하나의 거대한 인간-기계시스템으로써 작업자와 시스템간의 상호 작용이 얼마나 잘 이루어지는가에 따라 수행하고자 하는 직무와 수행도에 영향을 미치게 된다. 선교 내에는 시각표시장치뿐만 아니라 청각표시장치로부터 나오는 많은 신호들이 존재한다. 그 중 장비의 알람에 대한 인간의 인지능력에 대한 연구는 미흡한 상태이다. 본 연구에서는 청각적 아이콘과 함축적 소리를 비교$\cdot$평가하여 알람에 대한 작업자의 인지에 대해 연구 하였다. 실험결과 청각적 아이콘이 함축적 소리를 사용한 경우 보다 더 빠르고 정확하게 인지 할 수 있는 것으로 나타났다. 본 연구의 결과는 선교 내 청각표시장치의 성능 기준 그리고 현재 논의 되고 있는 통합선교알람시스템을 위한 기초 자료로 이용될 수 있을 것이라 생각된다.

본 연구는 2019 칸 국제광고제에서 수상한 작품들을 분석하여, 다섯 개의 주제를 가지고 크리에이티브 트렌드를 제시하였다. 다감각 경험, 크리에이티비티와 데이터와의 결합, 진정한 휴머니즘, 행동하는 브랜드, 그리고 사회 약자에 대한 배려라는 주제들이 글로벌한 크리에이티브 트렌드로서 많은 기업들이 소비자들에게 전달하고자 하는 메시지임을 확인했다. 단순한 시각적 자극에서 벗어나 소리 및 향기를 이용해 적극적으로 브랜드를 알리고자 하는 노력들은 기존에도 있었지만, 어떻게 새롭게 보여줄 것인가를 고민한 캠페인이 눈에 띄었다. 데이터들 속에서 의미 있는 소비자 인사이트를 찾아내 그것에 크리에이티비티를 더해 소비자들에게 감동을 주고, 결국 행동의 변화를 일으키고자 하는 캠페인들 역시 칸 국제광고제에서 호평을 받았으며, 진정한 휴머니즘을 바탕으로 한 광고들도 좋은 평가를 받았다. 기업의 철학 그리고 브랜드의 목적을 져버리지 않고 옳은 것을 행하는 '행동주의'에 앞장선 나이키의 사례는 큰 반향을 일으켰다. 마지막으로, 사회 약자인 장애인들을 배려한 프로젝트들 역시 2019 칸 국제광고제에서 수상했다.

In this study, a brain-basrd model for science teaching and learning was developed based on the natural processes which human acquire knowledge about a natural object or on event, the major domains of science educational objectives of the national curriculum, and the human brain's organizational patterns and functions. In the model, each educational objective domain is related to the brain regions as follows: The affective domain is related to the limbic system, especially amygdala of human brain which is involved in emotions, the psychomotor domain is related to the occipital lobes of human brain which perform visual processing, temporal lobes which perform functions of language generating and understandng, and parietal lobes which receive and process sensory information and execute motor activities of body, and the cognitive domain is related to the frontal and prefrontal lobes which are involved in think-ing, planning, judging, and problem solving. The model is a kind of procedural model which proceed fiom affective domain to psychomotor domain, and to cognitive domain of science educational objective system, and emphasize the order of each step and authentic assessment at each step. The model has both properties of circularity and network of activities. At classrooms, the model can be used as various forms according to subjects and student characteristics. STS themes can be appropriately covered by the model.

The purpose of this study was to investigate possible age differences in the attenuation of acceleration in the upper body (from pelvis through shoulder to head) during fast walking. Thirty young and 29 elderly subjects participated in this study. Wireless acceleration sensors were attached on head, shoulder, and pelvis. Subjects performed two trials of fast walking on a treadmill, where the fast speed was defined as 1.5 times of the comfortable speed. Root-mean-squared (RMS) accelerations of each axis were compared with age group and sensor position as independent factors. In the AP direction, the pelvis acceleration was greater in the young and the shoulder-to-head attenuation was also greater in the young (p<0.001), so that the head acceleration was comparable between age groups (p=0.581). In the ML direction, the pelvis acceleration was greater in the young and also the pelvis-to-shoulder attenuation was greater in the young (p<0.001), so that the head acceleration was greater in the elderly group (p<0.001). Insufficient attenuation ML acceleration in the elderly resulting in the greater acceleration in the head may deteriorate the balance control which utilize feedback signals from the sensory organs in head, e.g., vestibular and visual systems.

Background: Severe pain always develops after thoracotomy; intrapleural regional analgesia is used as a simple, safe technique to control it. This study was performed to evaluate whether a small dose of naloxone with local anesthetics prolongs sensory blockade. Methods: A prospective, randomized double-blinded controlled study was conducted on 60 patients of American Society of Anesthesiologists statuses I and II, aged 18 to 60 years, scheduled for unilateral thoracotomy surgery. After surgery, patients were randomly divided into two groups: through the intrapleural catheter, group B received 30 ml of 0.5% bupivacaine, while group N received 30 ml of 0.5% bupivacaine with 100 ng of naloxone. Postoperative pain was assessed using the visual analog pain scale (VAS). Time for the first request for rescue analgesia, total amount consumed, and incidence of postoperative complications were also recorded. Results: The VAS score significantly decreased in group N, at 6 h and 8 h after operation (P < 0.001 for both). At 12 h after injection, the VAS score increased significantly in group N (P < 0.001). The time for the first request of rescue analgesia was significantly longer in group N compared to group B (P < 0.001). The total amount of morphine consumed was significantly lower in group N than in the bupivacaine group (P < 0.001). Conclusions: Addition of a small dose of naloxone to bupivacaine in intrapleural regional analgesia significantly prolonged pain relief after thoracotomy and delayed the first request for rescue analgesia, without significant adverse effects.

Objective : Corpectomy of the first lumbar vertebra (L1) for the management of different L1 pathologies can be performed using either an anterior or posterior approach. The aim of this study was to evaluate the usefulness of a retroperitoneal extrapleural approach through the twelfth rib for performing L1 corpectomy. Methods : Thirty consecutive patients underwent L1 corpectomy between 2010 and 2016. The retroperitoneal extrapleural approach through the 12th rib was used in all cases to perform single-stage anterior L1 corpectomy, reconstruction and anterior instrumentation, except for in two recurrent cases in which posterior fixation was added. Visual analogue scale (VAS) was used for pain intensity measurement and ASIA impairment scale for neurological assessment. The mean follow-up period was 14.5 months. Results : The sample included 18 males and 12 females, and the mean age was 40.3 years. Twenty patients (67%) had sensory or motor deficits before the surgery. The pathologies encountered included traumatic fracture in 12 cases, osteoporotic fracture in four cases, tumor in eight cases and spinal infection in the remaining six cases. The surgeries were performed from the left side, except in two cases. There was significant improvement of back pain and radicular pain as recorded by VAS. One patient exhibited postoperative neurological deterioration due to bone graft dislodgement. All patients with deficits at least partially improved after the surgery. During the follow-up, no hardware failures or losses of correction were detected. Conclusion : The retroperitoneal extrapleural approach through the 12th rib is a feasible approach for L1 corpectomy that can combine adequate decompression of the dural sac with effective biomechanical restoration of the compromised anterior loadbearing column. It is associated with less pulmonary complication, no need for chest tube, no abdominal distention and rapid recovery compared with other approaches.

This study aimed to investigate the influence of Astragalus membranaceus (AM), Adenophora triphylla (AT), and Ulmus pumila (UP) extracts on the quality traits, palatability, and storage stability of sous-vide (SV) cooked chicken breasts. Chicken breasts were marinated in AM, AT, or UP extracts for 1 h, and then consistently cooked at a constant temperature of 60℃ for 2 h. SV cooked chicken breasts with the UP extract exhibited lower lightness and higher yellowness values on the surface region compared to those with the AM and AT extracts (p<0.05). The control and UP groups displayed a similar overall visual acceptability (p>0.05), although the UP group had lower color acceptability (p<0.01). The UP group also had higher flavor and lower off-flavor intensities compared to the control group (p<0.05), although similar scores were observed in tenderness attributes and juiciness among the groups (p>0.05). Owing to these results regarding overall sensory acceptability, samples from the UP group were more preferred by the trained panelists compared to samples from the control group (p<0.001). On 14 d of cold storage, all the groups with herbal medicinal extracts exhibited a lower concentration of thiobarbituric acid-reactive substances than the control group (p<0.05), and the AT and UP groups showed lower values compared to the AM group due to their higher flavonoid contents (p<0.001). Therefore, meat marination with herbal plant extracts before SV cooking can be effective for enhancing the overall quality of SV cooked chicken breast.

Objectives The objective of this study was to assess the effectiveness of acupotomy for carpal tunnel syndrome. Methods Based on seven domestic and foreign databases. We analyzed the randomized controlled trials using acupotomy for carpal tunnel syndrome. The treatment group was treated with acupotomy and the control group was no restrictions on treatment methods. Results In this study, the effect of acupuncture treatment for carpal tunnel syndrome was investigated. Each study reported that acupotomy could be an effective treatment for carpal tunnel syndrome. However, as a result of meta-analysis of Levine carpal tunnel syndrome questionnaire scores, visual analog scale, and sensory nerve conduction velocity, the results were more clinically significant than those of the control group. Due to the small number of randomized controlled trial studies and the nature of acupotomy treatment, blinding of interventions was impossible, resulting in a high risk of bias. Conclusions In this regard, it is thought that well-planned randomized controlled studies on patients with carpal tunnel syndrome are needed in the future to secure the clinical evidence for acupotomy treatment.
