Experimental Observations of Boiling and Flow Evolution in a Coiled Tube

P. Ye,X. F. Peng,H. L. Wu,M. Meng,Y. Eric Gong 대한설비공학회 2008 International Journal Of Air-Conditioning and Refr Vol.16 No.1

A sequence of visually experimental observations was conducted to investigate the flow boiling and two-phase flow in a coiled tube. Different boiling modes and bubble dynamical evolutions were identified for better recognizing the phenomena and understanding the two-phase flow evolution and heat transfer mechanisms. The dissolved gases and remained vapor would serve as foreign nucleation sites, and together with the effect of buoyancy, centrifugal force and liquid flow, these also induce very different flow boiling nucleation, boiling modes, bubble dynamical behavior, and further the boiling heat transfer performance. Bubbly flow, plug flow, slug flow, stratified/wavy flow and annular flow were observed during the boiling process in the coiled tube. Particularly the effects of flow reconstructing and thermal non-equilibrium release in the bends were noted and discussed with the physical understanding. Coupled with the effects of the buoyancy, centrifugal force and inertia or momentum ratio of the two fluids, the flow reconstructing and thermal non-equilibrium release effects have critical importance for flow pattern in the bends and flow evolution in next straight sections.

In order to reconstruct the traditional technology of Korean golden varnish coatings, this study was carried out to separate and determine some main coloring components of the exudates of D. morbifera and its traditionally refined golden varnishes using a process of solvent extractions, chromatographies and spectrometries. The results obtained are as follows: 1. The exudate and its traditional-refined golden varnishes appear to have a kind of natural polyacetylenes because it has some triple bond peaks in FT-IR spectrometry. 2. Some yellowing spots of the polar-solvent extrats from the exudates and refined varnishes separated on TLC appeared under natural drying condition, but those of non-polar solvent extract such as hexane did not. 3. A traditional refining method for reconstructing a Korea golden varnishes was thought to be better than solvent separation because the former had higher triple-bond peaks than the latter in FT-IR spectrometry. 4. One of main conponents in the hexane-extracts of the traditional-refined varnishes and the exudates had the same molcular weighr of 204, but the fragmentation patterns was a little different between the exudate and the refined. in LC-MS soectrometry.

임기표,정우양 한국목재공학회 1998 목재공학 Vol.26 No.1

In order to reconstruct the traditional technology of Korean golden varnish(Hwangchil) made from the exudates of D. morbifera, this study in the second step was carried out to analyze the chemical composition and oil properties of the exudates for coatings and bark extractives made from the trees of D. morbifera more than 20 years old grown in Wando and Jejudo islands in the southwestern part of Korean peninsula according to the physiological seasons. The results obtained are as follows: 1. The exudates appeared to be a phytoalexin because it exudated after several days in tapping only in summer season. 2. Both the exudates and bark-extracts with acetone contained 50∼60% unsaponifiables and 30∼50% saponifiables 3. A major component of essential oil in bark-extractives was β-cubebene and reached to 60∼80%, while that of exudates included only 34% β-cubebene and some other compounds such as β-cadinene of 12%, aromadendrene of 9%, β-selinene of 9%, CAS030021-74-0 of 10%, etc. in GC-MS spectrometer. 4. A major component of fatty oil fraction in bark-extractives was linoleic acid and reached to more than 60%, while the exudates had mostly other components such as terpenes and phenolics instead of fatty acids accordint to GC-MS spectrometer. 5. Iodine value of samples after oil refining had 214㎎/g in the exudates and more than than 150㎎/g in bark-extractives, so the latter belonged to a drying oil.. 6. Therefore, the exudates from D. morbifera for traditional Korean golden varnish seems to have been used to a good varnish because it has some specific compounds different from its bark-extractives or general varnishes.

Peer Smoking and Smoking-related Beliefs Among College Students in Bangladesh

Kamimura, Akiko,Ahmmad, Zobayer,Pye, Mu,Gull, Bethany The Korean Society for Preventive Medicine 2018 Journal of Preventive Medicine and Public Health Vol.51 No.1

Objectives: Smoking is a significant public health issue in Bangladesh. The purpose of this study was to examine peer smoking and smoking-related beliefs among college students in Bangladesh. Methods: College students at two universities in Dhaka, Bangladesh participated in a self-administered survey in May and June 2017. Results: First, being a current or former smoker is associated with lower levels of beliefs among respondents that they would not smoke even with smoker friends or nervousness, and lower levels of intentions that they would not smoke, while current smokers and former smokers have different smoking-related beliefs. Second, having smoker friends is associated with lower levels of intentions that they would not smoke. Third, higher levels of normative beliefs that it is important not to smoke are associated with higher levels of beliefs that they would not smoke even with smoker friends or nervousness, higher levels of intentions that they would not smoke, and higher levels of avoidance of smoking. Conclusions: Smoking-related beliefs and perceived norms in individuals' social networks are important components in promoting tobacco cessation in Bangladesh. But it is challenging to prevent or intervene in smoking because of the high rates of smoking in this country and the high prevalence of smokers in individuals' social networks. Future studies should examine the most effective interventions to combat smoking in high-smoking social networks, such as using mobile apps or social media, and evaluate the effectiveness of such interventions.

Cardiovascular Disease-related Health Beliefs and Lifestyle Issues Among Karen Refugees Resettled in the United States From the Thai-Myanmar (Burma) Border

Objectives: Refugees resettled in the US may be at risk for cardiovascular disease (CVD). However, little is known about CVD-related issues among Karen refugees who have migrated to the US from the Thai-Myanmar border. The purpose of this study was to examine CVD-related health beliefs and lifestyle issues among Karen refugees resettled in the US. Methods: Karen refugees resettled in the US from the Thai-Myanmar border (n=195) participated in a survey study on health beliefs related to CVD, salt intake, physical activity (PA), and smoking in the fall of 2016. Results: A high-salt diet, physical inactivity, and smoking were major lifestyle problems. Participants who adhered to a low-salt diet considered themselves to be susceptible to CVD. Most participants did not engage in regular PA. Regular PA was associated with less perceived susceptibility to CVD and greater perceived benefits of a healthy lifestyle for decreasing the likelihood of CVD. Conclusions: Each refugee population may require individualized strategies to promote PA and a healthy diet. Future studies should develop health education programs that are specifically designed for Karen refugees and evaluate such programs. In addition to health education programs on healthy lifestyle choices, tobacco cessation programs seem to be necessary for Karen refugees. At the same time, it is important to foster strategies to increase the utilization of preventive care among this population by promoting free or reduced-fee resources in the community to further promote their health.

정신장애인 회복과정 영향 요인

강석임(Seok Im Kang),이용표(Yong Pye Lee) 한국정신건강사회복지학회 2013 정신보건과 사회사업 Vol.41 No.4

정신장애인을 대상으로 그들의 회복 지향점이고 목표인 지역사회통합을 이루는 데 스트레스, 사회적 자원 및 지역사회통합 간의 관계를 스트레스 대처이론으로 검증하였다. 상당수의 기존연구들이 스트레스 대처이론을 이용하여 연구하였지만 정신장애인을 대상으로 스트레스 대처이론을 검증한 연구는 거의 없으므로, 이 연구를 통해 스트레스 대처이론이 정신장애인에게도 적용되는지 파악하고자 한다. 이를 위해 서울ㆍ인천ㆍ경기지역과 충청도에 위치한 사회복귀시설 또는 정신보건센터를 이용하는 정신장애인 415명의 자료를 분석에 사용하였다. 구조방정식 모형을 사용하여 정신장애인의 지역사회통합에 대한 예측요인을 분석한 결과, 스트레스 요인인 증상과 낙인은 모두 지역사회통합에 직접적인 영향을 미치는 것으로 나타났고, 스트레스 요인인 증상이 많이 발생할수록, 그리고 낙인의 지각이 높을수록 지역사회통합이 낮아지지만 부모, 형제, 전문가 등의 사회적 지지는 정신장애인의 지역사회통합을 부분적으로 매개하는 것으로 나타났다. 이상의 결과를 바탕으로 정신장애인의 회복의 지향인 지역사회통합에 스트레스 요인이 부정적 영향을 미치는 과정에서 사회적 지지는 스트레스 요인을 완화시켜주는 대처자원임을 확인 하였고, 이를 위한 실천적 함의를 논의하였다. The relationship of stress and social resources to community integration among the person with Psychiatric Disabilities were analyzed based on a stress-coping theory, as community integration is the ultimate goal of their rehabilitation. Stress-coping theories have been utilized in lots of earlier studies, but few studies have ever attempted to apply this kind of theory to the person with Psychiatric Disabilities. Therefore it`s meant in this study to analyze whether a stress-coping theory could be applied to the person with Psychiatric Disabilities. What factors predicted the community integration of the person with Psychiatric Disabilities were analyzed by using a structural equation model. As a result, both of symptoms and perceived stigma that were stressors were found to exert a direct influence on community integration, and more symptoms and more perceived stigma that were stressors led to less successful community integration. But social support from parents, siblings and experts had a partial effect on the community integration of the person with Psychiatric Disabilities. The above-mentioned findings of the study ascertained that social support was one of coping resources available to relieve the stressors while the stressors had a negative impact on community integration which was the ultimate goal of the rehabilitation of the person with Psychiatric Disabilities. And the practical implications of the findings of the study were discussed.
