Pavilions are aesthetic buildings harmonized with the surrounding landscape in ancient and modern time and space. They have unique open structures that were sited a short distance from a main residence. Pavilions were constructed for the purpose of resting and cultivating of minds through communion with nature. They were also established to use as places for building human network among men of letters. Pavilions are seen in China and Korea. They are called as 'Nujeong' in Korea. Nujeongs are not only for resting, but also for aesthetic thinking of ancient Korean writers. They are generally designed to provide visitors with a space where they can rest physically as well as spiritually and stimulate their own imaginations. Phrases that are widely used on the signboards of Nujeongs are Huehuejeong(休休亭), Manhuejeong(萬休亭), Sigyoungjeong(息影亭), Nongwoljeong(弄月亭), Gunzijeong(君子亭), Geoyeonjeong(居然亭).

Background: Indoor air pollution can cause and exacerbate asthma. We report a previously undescribed case of occupational asthma related to indoor air pollution in a worker at an indoor air gun shooting range and highlight the potential risk of developing occupational asthma in this environment. Case presentation: A 31-year-old man presented with dyspnea, cough, and sputum and was diagnosed with asthma complicated by pneumonia. Objective evidence of asthma was obtained by performing a methacholine bronchial provocation test. It was suspected that the patient had occupational asthma, which began one month after changing jobs to work within the indoor air gun shooting range. The highest peak expiratory flow (PEF) diurnal variability on working days was 15%, but the highest variation was 24%, with 4 days out of 4 weeks having a variation of over 20% related to workplace exposure. Conversely, the diurnal variability on the rest days was 7%, and no day showed a variation exceeding 20%. The difference in the average PEF between working and rest days was 52 L/min. PEF deterioration during working days and improvement on rest days were noted. Conclusions: The results obtained from the in-depth analysis of the PEF were adequate to diagnose the patient with occupational asthma. Exposure to indoor air pollution and lead and the patient's atopy and allergic rhinitis may have contributed to the development of occupational asthma.

Background The masseter nerve is a useful donor nerve for reconstruction in patients with established facial palsy, with numerous advantages including low morbidity, a strong motor impulse, high reliability, and fast reinnervation. In this study, we assessed the results of masseter nerve-innervated free gracilis muscle transfer in established facial palsy patients. Methods Ten patients with facial palsy who received treatment from January 2015 to January 2017 were enrolled in this study. Three patients received masseter nerve-only free gracilis transfer, and seven received double-innervated free gracilis transfer (masseter nerve and a cross-face nerve graft). Patients were evaluated using the Facial Assessment by Computer Evaluation software (FACEgram) to quantify oral commissure excursion and symmetry at rest and when smiling after muscle transfer. Results The mean time between surgery and initial movement was roughly 167.7 days. A statistically significant increase in excursion at rest and when smiling was seen after muscle transfer. There was a significant increase in the distance of oral commissure excursion at rest and when smiling. A statistically significant increase was observed in symmetry when smiling. Terzis' functional and aesthetic grading scores showed significant improvements postoperatively. Conclusions Masseter nerve innervation is a good option with many uses in in established facial palsy patients. For some conditions, it is the first-line treatment. Free gracilis muscle transfer using the masseter nerve has excellent results with good symmetry and an effective degree of recovery.

Objective: The growth and development of the mandible strongly depend on modeling changes occurring at its ramus. Here, we investigated covariance patterns between the morphology of the ramus and the rest of the face. Methods: Lateral cephalograms of 159 adults (55 males and 104 females) with no history of orthodontic treatment were collected. Geometric morphometrics with sliding semi-landmarks was used. The covariance between the ramus and face was investigated using a two-block partial least squares analysis (PLS). Sexual dimorphism and allometry were also assessed. Results: Differences in the divergence of the face and anteroposterior relationship of the jaws accounted for 24.1% and 21.6% of shape variation in the sample, respectively. Shape variation was greater in the sagittal plane for males than for females (30.7% vs. 17.4%), whereas variation in the vertical plane was similar for both sexes (23.7% for males and 25.4% for females). Size-related allometric differences between the sexes accounted for the shape variation to a maximum of 6% regarding the face. Regarding the covariation between the shapes of the ramus and the rest of the face, wider and shorter rami were associated with a decreased lower anterior facial height as well as a prognathic mandible and maxilla (PLS 1, 45.5% of the covariance). Additionally, a more posteriorly inclined ramus in the lower region was correlated with a Class II pattern and flat mandibular plane. Conclusions: The width, height, and inclination of the ramus were correlated with facial shape changes in the vertical and sagittal planes.

18세에서 30세 중반 사이의 남자 35명 여자 21명 총 56명을 대상으로 2시간 동안 VDT 작업을 하도록 한 후, 안구 및 전신 증상 등을 조사하고 순목 횟수, 눈물층파괴시간(BUT), 안검열의 높이, 시력, 타각적 굴절력, 조절력 등을 측정하였다. 안구증상에서는 눈의 피로를 느끼는 사람이 34%로 가장 많았고 시기능증상에서는 물체가 흐려 보이는 증상이 83%, 전신증상에서는 어깨가 아픈 사람이 38%로 가장 높게 나타났다. VDT 작업 중의 순목 횟수가 8/min로 휴식 때의 22/min에 비해 많이 감소했다. VDT 작업 직후의 눈물층파괴시간도 약 7초로 작업 전의 약 12초보다 현저히 감소되었다. 안검열의 높이는 작업 전 7.69mm보다 작업 중에는 9.04mm로 증가하였다. 평균 나안시력은 VDT 작업 전에 0.63에서 작업 후에는 0.57로 약 9.5% 감소하는 경향을 보였고, 타각적 굴절이상은 0.28D 정도 근시화 경향이 보였다. VDT 작업 후 조절력은 1.49D 정도 감소하였는데 주로 조절근점 굴절력의 감소가 원인인 것으로 보인다. 폭주근점 굴절력도 0.87D 감소하였다.

Coherence can be used to evaluate the functional cortical connections between the motor cortex and muscle. This study is to find coherence between EEG (electroencephalogram) and EMG (electromyogram) evoked by movement of a hand. Seven healthy participants were asked to perform thirty repetitive movement of right hand for ten seconds with rest for ten seconds. Specific feature of EEG components has been extracted by ICA (independent component analysis) and coherence between EEG and EMG was analyzed from data measured EEG in five local areas around central part of head and EMG in flexer carpri radialis muscle during grabbing movement. Coherence between EEG and EMG was successfully obtained at 0.025 confidence limit during hand movement and showed significant difference between rest and movement at 13-18Hz.

In this paper, the optimal torque shaping is obtained for 3-axis rotation of a spacecraft. The true optimal 3-axis rotation of rigid spaeraft is first investigated via parameter optimization method with prescribed switching times. Input torque shape of the troque generating device mounted on the central hub is optimized using fourier Series expansion so that the spacecraft may slew while minimizing the vibration energy of flexible modes. Numerical results show that proposed method suggests a reference trahectory for open-loop control, and also verify that it can minimize the vibratory modes of the spacecraft during/after the rest-to-rest maneuver.

Complex regional pain syndrome (CRPS) type II is a syndrome that develops after nerve injury. Symptoms may be severe, and vary depending on the degree of sympathetic nerve involvement. As yet, there is no satisfactory treatment. We report the case of a female patient who had an L5 left transverse process fracture and an S2 body fracture, who developed symptoms of CRPS type II in her left lower leg that were aggravated during ambulation in spite of absolute bed rest for one month after the trauma. Several treatments, including bed rest, medication, and numerous nerve blocks were attempted, but the pain persisted. We finally tried injection of polydeoxyribonucleotide (PDRN) solution at the left L5 transverse process fracture site because we knew of the anti-inflammatory effect of PDRN. One day after this treatment, her symptoms had almost disappeared and three days later, she was discharged. We will also further discuss the possibility of using PDRN solution for the treatment of CRPS.
