The present work addresses structural characteristics of natural gas flames in a lean premixed swirl-stabilized combustor with an attention focused on the effect of the formation of recirculation zones on the combustion instability. It is known that the recirculation zone plays an important role in stabilizing a turbulent, premixed natural gas flames by providing a source of heat or radicals to the incoming premixed fuel and air. To improve our understanding of the role of recirculation zones, the flame structure was investigated for various mixture velocities, equivalence ratios and swirl numbers. The optically accessible combustor allowed for the application of laser diagnostics, and Particle Image Velocimetry(PIV) measurements was used to characterize the flame structure under both cold flow conditions and hot flow conditions. Dynamic pressures were also measured to investigate characteristics of combustion at the same time. The results indicates that the formation of recirculation zone is strongly related to the occurrence of thermo-acoustic instabilities.

Sweating is natural phenomenon necessary for the regulation of an individual's body-temperature. The secretion of sweat is mediated by a portion of our vegetative nervous system(the sympathetic nervous system). In some people, this system is working at a very high activity level, far higher than needed to keep a constant temperature. This condition is referred to as hyperhidrosis. Especially excessive sweating of the hands and the feet is palmoplantar hyperhidrosis or volar hyperhidrosis. This is by far the most distressing condition. It was founded that the first important cause of this was emotional factor. The hands are much more exposed in social and prefessional activities than any other part of our body. Many individuals with palmoplantar hyperhidrosis are limited in their choice of proffession, because unable to manipulate materials sensitive to humidity or reluctant to shake hands; some patients arrive to the point to avoid social contact. The occidental medical treatments for palmoplantar hyperhidrosis include application of topical agents(chemical antiperspirants such as aluminum chloride), iontophoresis(treatment with electrical current), or surgery(thoracic sympathectomy). It was reported that the most effective treatment was thoracic sympathectomy. So this study was started to find the easy and effective oriental medical treatments against the occidental medical treatments through the oriental medical literature. The occidental medical idea for palmoplantar hyperhidrosis is only limited in neurologic system, so surgery is the best treatment. But the oriental medical idea for palmoplantar hyperhidrosis is much wider, so the oriental medical causes and treatments for this are able to be veriety. And the oriental medical teatment is freely in treating the patients of palmoplantar hyperhidrosis, because entire idea including pulse, facial color, mental condition, constitution and other symptom exists in the oriental medicine. The results of a bibliographic study of causes and treatments for palmoplantar are as follows; 1. The main causes of pa1moplantar hyperhidrosis are heat in the stomach, damp-heat in the spleen and the stomach, insufficiency of the spleen-qi and the stomach-qi, deficiency of the spleen-yin and the stomach-yin, and the others are the stomach-cold syndrome, stasis of blood and dyspepsia in the stomach, disorder of the liver-qi, deficiency of the heart-yin and the kidney-yin, deficiency of the heart-yang and the kidney-yang, stagnated heat in the liver and the spleen, the lung channel-heat etc. 2. The main methods of medical treatments for palmoplantar hyperhidrosis are clearing out the stomach-heat, eliminating dampness and heat in the spleen and the stomach, invigorating the spleen-qi and the stomach-qi, reinforcing the spleen-yin and the stomach-yin, warming the stomach, relaxing the liver and alleviating of mental depression and tonifying the heart and the kidney etc. 3. The main prescriptions of palmoplantar hyperhidrosis are Taesihotang, Palmultang-kakam, Samyeongbaechusan, Chongbisan, Sasammaekmundongtang, the others are Leejungtang, Hwangkikonjungtang, Seungkitang, Boyumtang, Baekhotang, Chongsimyonjayum, Moyrosan, etc. 4. Local medicine for external use are liquid after boiling alum in water for about 1 or 2 hours, liquid after boiling alum and pueraria root in water and liquid after boiling stragalus root, pueraria root, ledebouriella root and schizonepeta in water, etc. 5. The methods of acupuncture therapy include invigorating Bokyru, Yumkuk and purgating Hapkouk, or invigorating Bokyru, Kihae and purgating Hapkouk, or steadying Hapkouk, Nokung.

Objectives The purpose of this study is to analyze some of the TCM (traditional Chinese medicine) clinical research literatures about pediatric night crying in order to learn clinical application of Korean medicine treatment for pediatric night crying. Methods We searched clinical trial literatures about TCM treatment of pediatric night crying from the CNKI (China National Knowledge Infrastructure) (January 2000 to June 2018). We analyzed the literature in regards to the treatment methods and the results. Results Among the 459 searched studies, 13 randomized controlled trials and 41 case studies were selected and analyzed. In most of the studies, the effectiveness of TCM in treating patients was significantly high, so we confirmed the effectiveness of TCM on pediatric night crying. The most commonly used pattern differentiations (辨證) were Spirit damage due to fright and fear (驚恐傷神), Spleen deficiency and cold (脾虛寒) and Heart fire heat (心火熱). Methods of treatment include herbal medicines (internal medicine and external application), massage therapy (Tuina methods), acupuncture and other treatments (bloodletting). The most commonly used herb medicines were Cicadidae Periostracum (蟬?), Poria Cocos (茯?), Glycyrrhizae Radix (甘草), Uncariae Ramulus et Uncus (釣鉤藤), Junci Medulla (燈心草), Fossilia Ossis Mastodi (龍骨), Atractylodis Rhizoma Alba (白朮), Cinnabaris (朱砂), and Coptidis Rhizoma (黃連). The most commonly used massage methods were Clearing Liver Channel (淸肝經), Clearing Heart Channel (淸心經), Kneading $Xi{\check{a}}oti{\bar{a}}nx{\bar{i}}n$ (?小天心), Supplementing Spleen Channel (補脾經), Clearing $Ti{\bar{a}}nh{\acute{e}}shu{\check{i}}$ (淸天河水), and Rubbing Abdomen (摩腹). Conclusions Based on the results of clinical studies from China, the use of Korean medicine for the treatment of pediatric night crying has been shown to be effective in relieving symptoms. Based on the results of this study, it is possible to widen the scope of Korean medicine by additionally reviewing clinical and experimental studies on pediatric night crying.

Geothermal heat pump system (GHPS) is an energy-efficient technology that use the relatively constant and renewable energy stored in the earth to provide heating and cooling. With the aim of using GHPS as a heating source, it's possibilities of application in farrowing house were examined by measuring environmental assessment and sow's performance. A total of 96 sows were assigned to 2 pig housings (GHPS and conventional housing) with 48 for four weeks in winter season. During the experimental period, indoor maximum temperature in GHPS-housing was measured up to $26.7^{\circ}C$, average temperature could maintain $21.2^{\circ}C$. The mean value of dust levels and $CO_2$, $NH_3$ and $H_2S$ gas emissions were decreased in GHPS-housing compare with those of conventional housing. Litter size, birth weight, parity and weaning weight did not differ between housings. However, feed intake of sow in GHPS-housing was lower than that of conventional housing. In energy consumption for heating, electric power consumption increased in GHPS-housing than the conventional housing, a 2,250 kwh increase, whereas there is no fuel usage for heater in GHPS-housing. Amount of ground water circulated for heating in cold weather for earth heat exchanger was 8.4-12.9 ton per day. In conclusion, GHPS may have environmental benefits and effectiveness of heating in farrowing housing and affect the performance in sows.

Wang Cheong-Im(1768-1831) in the Ching dynasty conducted the therapy of blood statis syndrome using the methods for promoting blood circulation and removing blood statis in accordance with the description in the book Uirimgaechak(醫林改錯). Thus, this study examined his methods for promoting blood circulation and removing blood statis, therapy of blood statis syndrome and mechanism of function. Since the blood statis symptoms varied on the parts where the blood statis were occurred, the therapy for promoting blood circulation and removing blood statis applied different treatments and drugs depending on the symptoms. The therapy also valued much of qi and blood. Qi is important to the human body so that the therapy replenished qi and simultaneously promoted the blood circulation as mainly focusing on the regulation of the qi flow. Moreover, the therapy adjusted the level of removing blood circulation and rate of replenishing qi. The degree of prescription and drug was differentiated in treating a variety of blood statis because of the difference in the seriousness and characteristics of blood circulation, amount and application of drug and combination of drugs. The therapy was careful about the regulation of qi for the replenishment of qi and the nurishment of blood for the promotion of blood circulation. If the blood circulation was blocked, the blood statis was formed. Accordingly, the phlegm and the blood statis were closely related. Then, the phlegm and blood statis were simultaneously treated. The therapy divided the properties of blood statis into the stagnant excess syndrome, the stagnant deficiency syndrome, the stagnant cold syndrome and the stagnant heat syndrome and treated the patients suitable for each symptom. The function of mechanism in the treatment using the methods for promoting blood circulation and removing blood statis was divided into the stagnation of blood and interruption in blood circulation. The therapy laid stress on promoting blood circulation and removing blood circulation. With such emphasis, the therapy facilitated the circulation in the bloood vessel, prevented the coagulation of blood, removed the blood statis and promoted the metabolism. Then, the physiological function and pathological change internal organs were improved. Furthermore, the therapy strengtened the heart and promoted the blood circulation by improving the systemic blood circulation. Moreover, the therapy facilitated the micro-circulation by adjusting the balance of body.
