This study was carried out to develop a new stalk curing of the horizontal hanging method that would reduce the harvesting and curing labor, and improve its quality of cured leaf than the conventional stalk curing method in burley tobacco. The horizontal hanging stalk-curing method designed from 1988 was compared with the conventional method. The horizontal method shortened the curing Period for 7 days and reduced to 0.3%, while it occurred 9.4% in the vertical method. In the horizontal method, the quality of cured leaf improved 9%, but the contents of chemical components and physical properties were similar to those of vertical method. The labor of stalk-cut and loading in curing facility reduced 28% by the horizontal method. In harvesting and curing process, the horizontal method resulted 12% of labor saving as compared with the vertical method. Key words : horizontal hanging stalk-curing method, vertical method, stalk-curing.

Hanging sleepers, which are not fully supported between the sleepers and the ballast, could cause large dynamic forces especially on high speed ballasted track. The dynamic forces resulting from insufficient supporting forces may badly affect the running stability and safety of train. These also accelerate track irregularities and deteriorate track components rapidly. Consequently, the hanging sleepers will lead to sharp increases in track maintenance cost. This paper introduces a rapid and easy method to detect hanging sleepers with portable light falling weight deflectometer (LFWD) and summarizes the results of experiments performed at the high speed ballasted track.

관우를 모신 동관왕묘에는 51점의 현판이 소장되어 있다. 이것들은 조선의 국왕이나 명 청대 사신 및 장군들이 쓴 것이다. 그동안 현판에 대한 연구는 궁궐에 소장된 것들이 주로 연구되었고, 동관왕묘의 것은 거의 이뤄지지 않았다. 이에 본고에서는 조선후기 국왕의 글씨로 만든 현판을 연구대상으로 삼아, 그 내용과 형식을 분석하였다. 내용상으로는 현판의 제작자와 제작시기 및 제작배경을, 형식상으로는 현판의 유형과 재료 및 시기별 양식 변천을 밝혀 보았다. 이를 통해 알게 된 사실은 다음과 같다. 우선, 동관왕묘에 국왕 글씨로 만든 현판은 총 7점이 현존하고 있다. 숙종이 쓴 1점, 영조가 쓴 4점, 고종이 쓴 2점이 그것이다. 이것들은 건물의 이름을 쓴 편액(扁額)과 동관왕묘에 방문한 느낌을 시로 쓴 시액(詩額)으로 나뉘었다. 특히 후자는 국왕이 봄과 가을에 능행(陵幸)하면서 동관왕묘에 들렀을 때 썼으며, 관우의 의리와 충성을 통해 왕실의 안녕을 도모하고자 의도한 내용이 포함되어 있다. 다음, 국왕의 현판은 명 청대 사신이나 장군의 것들과 비교할 때 재료나 형식면에서 차별화되었다. 바탕은 청색[회회청(回回靑) ]이나 주색[주칠(朱漆)] 및 옻색[흑칠(黑漆)]으로서, 먹색[묵(墨)]이나 흰색[분질(粉質)]으로 된 현판보다 고급 재료로 칠하였다. 글씨는 양각으로 새긴 위에 금(金)으로 칠하였다. 현판의 형식은 4면이 모판처럼 $45^{\circ}$로 비스듬하며 단청기법으로 꽃문양이나 칠보문양을 그렸고, 그 좌우와 아래로 길게 빼 당초문양을 장식하였다. 이것은 '사변형(斜邊形)'이라고 부르는 형식이며, 나머지 3종류의 형식보다 품격이 높아 최고 수준의 것이었다. 이처럼 국왕의 글씨를 새긴 현판의 존재를 통해 조선후기에 동관왕묘는 국왕들이 관심을 가지고 있었고, 군인들의 충성심을 강조한 정치적 공간으로서의 위상도 확인할 수 있었다. 이밖에 명대 사신이나 청대 장군의 글씨로 제작된 현판과 형식 비교나 시기별 양식적 변천은 다음 기회로 미루고자 한다.

Purpose: This study aimed to recognize the frequency of near-hanging patients with elevated Troponin-I (Tn-I), to obtain information necessary for treatment and prediction of prognosis by analyzing the clinical feature of near-hanging patients, and to evaluate the relevance of elevated Tn-I to abnormal result of other cardiac-related examinations. Methods: A retrospective review for the near-hanging patients, clinical record was conducted at two urban training hospitals between April, 2001 and December, 2011. We divided included patients into two groups, which one with elevated Tn-I level ($Tn-I{\geq}0.1ng/dL$) and one without it, and compared the differences in initial vital signs, cardiac enzyme tests, an electrocardiogram, echocardiography, chest X-ray, and the clinical outcomes. Results: A total of 39 patients were included, out of them, 14 patients showed rise in Tn-I level. The length of hospital stay and ICU hospitalization was more prolonged in the patient group with elevated Tn-I level than non-elevated group. As well as the incidence of endotracheal intubation and abnormal findings in echocardiography or chest X-ray was higher in the Tn-I elevated group, which is statistically significant. Conclusion: The rising of serum Tn-I level in near-hanging patients were not uncommonly observed. We believe that the cardiac-related test including Tn-I is necessary for near-hanging patients, and those who are shown abnormal result in cardiac-related test may need close observation and intensive care.

Shake table tests were conducted on scaled tunnel model to investigate the mechanism and effect of seismic loadings on horseshoe scaled tunnel model in ground fissure site. Key technical details of the experimental test were set up, including similarity relations, boundary conditions, sensor layout, modelling methods were presented. Synthetic waves and El Centro waves were adopted as the input earthquake waves. Results measured from hanging wall and foot wall were compared and analyzed. It is found that the seismic loadings increased the subsidence of hanging wall and lead to the appearance and propagation of cracks. The values of acceleration, earth pressure and strain were greater in the hanging wall than those in the foot wall. The tunnel exhibited the greatest earth pressure on right and left arches, however, the earth pressure on the crown of arch is the second largest and the inverted arch has the least earth pressure in the same tunnel section. Therefore, the effect of the hanging wall on the seismic performance of metro tunnel in earth fissure ground should be considered in the seismic design.

A numerical model of hydraulic resistance by hanging aquaculture facilities is developed and applied to a model basin and a field. A drag stress term formulated by the quadratic law of drag force is introduced Tn the equations of motion for a two-dimensional depth-averaged flow. In the model basin, numerical experiments ave tarried out for the various shape of obstructions, string density and layout of facilities etc.. The flow pattern around the facilities is affected sensitively by the density of string and the layout of facilities. On the other hand, the velocity decay due to the hanging oyster aquaculture facilities is observed in Kamak bay, where the maximum velcocity decay rate is $25\%$ in spring tide. The model is also applied to the field, Kamak bay. The velocity decay rate in the model is comparable with the field measurement data. The velocity decreases around the down-stream area of the facilities, .hut it increases in the other region. The water elevation decreases during the flood and it increases during the ebb.

A coupled analysis of a floating crane barge with a crane wire and hanging structure is carried out in thetime domain. The motion analysis of the crane barge is based on the floating multi-body dynamics, and thecrane wire is modeled as a simple spring tension. The hanging structure is assumed to be a rigid body with 3 degree-of-freedom translational motion. In this study, numerical simulations were conducted at three different stages. First, the developed code was validated by comparing the time-domain motion response of a crane barge with the frequency-domain results. Then, a coupled analysis of a crane barge and simple structure hanging by the crane wire was performed using the present scheme. The motion response and wire tension from the present calculations are compared with the results of OrcaFlex. The agreement between the two sets of results isfairly good. Last, lowering simulations in regular and irregular waves were conducted considering buoyancy changes in the hanging structure. The effects of the wave conditions, structure's weight, wire length, and lowering speed on the wire tension are considered.

A novel sample pretreatment technique, headspace hanging drop liquid phase microextraction (HS-LPME) was studied and applied to the determination of flavors from solid clove buds by gas chromatography-mass spectrometry (GC-MS). Several parameters affecting on HS-LPME such as organic solvent drop volume, extraction time, extraction temperature and phase ratio were investigated. 1-Octanol was selected as the extracting solvent, drop size was fixed to 0.6 $\mu$L. 60 min extraction time at 25 ${^{\circ}C}$ was chosen. HS-LPME has the good efficiency demonstrated by the higher partition equilibrium constant ($K_{lh}$) values and concentration factor (CF) values. The limits of detection (LOD) were 1.5-3.2 ng. The amounts of eugenol, $\beta$-caryophyllene and eugenol acetate from the clove bud sample were 1.90 mg/g, 1.47 mg/g and 7.0 mg/g, respectively. This hanging drop based method is a simple, fast and easy sample enrichment technique using minimal solvent. HSLPME is an alternative sample preparation method for the analysis of volatile aroma compounds by GC-MS.

The brachial plexus is a network of nerves that provides movement and feeling to the shoulder, arm and hand. The majority of acute brachial plexus injuries occur when the plexus is stretched violently or torn. This happens as result of the shoulder being pressed down forcefully while the head is pushed up and away from that shoulder. Such injuries frequently result from automobile or motor-cycle accidents or from falls and usually affect one side. Nerve injuries vary in severity from a mild stretching of the nerve to a tearing of the nerve root away from the spinal cord. We experienced a 50-year-old woman with weakness in both upper extremities after an attempted hanging. A consecutive workup revealed bilateral brachial plexus injuries. Six months after the incident, she had fully recovered. This is a very rare case of bilateral brachial plexus injuries after an attempted hanging.

Diabetic foot ulcers are a severe complication of diabetes, and their management requires a multidisciplinary approach for optimal management. When treating these ulcers, limb salvage remains the ultimate goal. In this article, we present the "hanging" free flap for the reconstruction of chronic lower extremity diabetic ulcers. This two-staged approach involves standard free flap harvest and inset; however, following inset the "hanging" pedicle is covered within a skin graft instead of making extraneous incisions within the undisturbed soft tissues or tunnels that can compress the vessels. After incorporation, a second-stage surgery is performed in 4 to 6 weeks which entails pedicle division, flap inset revision, and end-to-end reconstruction of the recipient vessel. Besides decreasing the number of incisions on diabetic patients, our novel technique utilizing the "hanging" pedicle simplifies flap monitoring and inset and allows reconstruction of recipient vessels to reestablish distal blood flow.
