Objective : This study researched the application of Sa-am acupuncture for the treatment of hiccup. Methods : We investigated the literature for Sa-am acupuncture treatment and traditional acupuncture treatment for hiccup. Result & Conclusion : In traditional oriental medicine, hiccup is considered to be caused by uprising stomach gi, whereas, in Sa-am acupuncture, it is considered to be caused by weakness and impurity of lung gi. In Sa-am acupuncture, hiccup is divided into five classes; reverse hiccup (treated with large intestine tonification), wind hiccup (treated with liver tonification), fire hiccup (treated with heart tonification), damp hiccup (treated with spleen tonification) and cold hiccup (treated with kidney tonification). In traditional oriental medicine, hiccup is treated by way of lowering the uprising stomach gi, while, in Sa-am acupuncture, hiccup is treated by way of removing whichever of the original cause of hiccups (impurity of large intestine, damage to liver, dry heat of heart, impairment of spleen, exhaustion of kidney) caused the weakness and the impurity of lung gi. In Sa-am acupuncture, the therapeutic mode for all the five causes of hiccups is tonification mode.

Major industrial accidents in which workers die due to fires or explosions while working at chemical substance handling workplaces continue to occur. Among the major industrial accidents that occurred between 2005 and 2021, the accident status by work situation and equipment was analyzed. Through analysis, it was confirmed that storage, reaction, and piping facilities were the main causes of the accident, and a self-checklist for each facility was developed. Verification was conducted through the supply and use groups to evaluate the suitability of the use, duties, and items of the self-checklist. The user group showed higher satisfaction than the supplier group for all three suitability of use, job, and item. In particular, since the inspection items of the self-checklist were organized around the cause of the accident derived through the analysis of actual accident cases, the satisfaction level was high in all groups. It is expected that the self-checklist developed through this study will be useful not only for large companies but also for small and medium-sized chemical industries that lack professional manpower.

Research has been conducted in many fields for the zero energy of domestic buildings. Among them, the development of insulation has become an essential element. Accordingly, researches are being made to improve the performance of organic insulating materials, and PF boards having the lowest thermal conductivity among organic insulating materials have been in the spotlight. However, problems have arisen due to the problems of durability of insulation materials such as PF boards and past acidification, and the durability of insulation materials is deteriorated when moisture or water enters due to crack gaps during the insulation of the basement layer or the external insulation method. In regard to the durability of the insulation, when the organic insulators of different kinds were placed in water, the pH was weakly basic in all organic insulation materials except PF, and the PF was about 4 pH. As a result, the PF should be continuously reviewed, and further analysis should be carried out to determine what causes acidification.

CFRP composites are used as primary structural members in various industrial fields because their specific strength and specific stiffness are excellent in comparison to conventional metals. Their usage is expanding to high added-value industrial fields because they are more than 50% lighter than metals, and have excellent heat resistance and wear resistance. However, when CFRP composites suffer impact damage, destruction of fiber and interface delamination occur. This causes an unexpected deterioration of strength, and for this reason it is very difficult to ensure the reliability of the excellent mechanical properties. Therefore, for the destruction mechanism in bending with impact damage, this study investigated the reinforcement data regarding various external loads by identifying the consequential strength deterioration. Specimens were damaged by impact with a steel ball propelled by air pressure. Decrease in bending strength caused by the tension and compression of the impact side, and depending on the lamination direction of fiber and interface inside the specimen. From the bending test it was found that the bending strength reduced when the impact energy increased. Especially in the case of compression on the impact side, as tensile stress occurred at the damage starting point, causing rapid failure and a substantially reduced failure strength.

전력선이 통과하는 지역에서 발생된 산불은 계통 섬락사고의 원인이 되고 있다. 본 연구에서는 연소화염에 의한 전력선의 절연내력 저하특성을 알아보기 위해 직류 및 교류 전압 인가 시, 연소화염과 고전압 도체의 수평거리(s)를 변화시켰을 때, 수직형 모델 전력선에 대한 섬락특성을 조사하였다. 실험 결과, 수평거리(s)가 작은 범위에서는 화염이 모델선로의 섬락전압을 크게 감소시킬 수 있는 것으로 나타났다. 이러한 섬락전압의 저하요인을 해석하기 위해 화염주변의 상대공기밀도가 고려되었으며, 화염이 존재하는 경우에는 그 영향이 매우 크게 나타남을 알 수 있었다.

Objectives : Multiple sclerosis (MS) is a demyelination disease of central nervous system, presenting a various neurological disorders depending on the lesion. In the view of oriental medicine, MS is similar to Flaccidity-syndrome(痿證). Also, since MS is a chronic disease which repeats the recurrences with periods of remission of the symptoms in between, it may usually be accompanied by depression. However, the etiology, treatment, and cause of recurrence of MS remain unknown, and also, as the recurrences of MS have been repeated, disease burden has been accumulated, which aggravates disorder. This case of MS experienced depression after the patient had been diagnosed as bad consequence based on the past 5 times recurrences of multiple sclerosis. Methods : We saw the causes as vicera and bowels functional disorder which might have come from a poor diet. Thus, we diagnosed this case as dual deficiency of spleen and kidney(脾腎兩虛), stagnant qi transforming into fire(氣鬱化火) and liver-kidney deficiency(肝腎不足) and treated it with Herb medication, acupuncture therapy, and supportive therapy, making the patient better. Results : We have improved the patient's condition to the time before 5th recurrence. Conclusions : This result suggests that our oriental medical treatments was effective on multiple sclerosis with depression.

Plant water deficiency during drought season causes physiological stress and can be a critical indicator of forest fire vulnerability. In this study, we attempt to analyze the spectral characteristics of water stressed vegetation by using the laboratory measurement on leaf samples and the canopy reflectance spectra extracted from satellite hyperspectral image data. Leaf-level reflectance spectra were measured by varying moisture content using a portable spectro-radiometer. Canopy reflectance spectra of sample forest stands of two primary species (pine and oak) located in central part of the Korean peninsula were extracted from EO-l Hyperion imaging spectrometer data obtained during the drought season in 2001 and the normal precipitation year in 2002. The preliminary analysis on the reflectance spectra shows that the spectral characteristics of leaf samples are not compatible with the ones obtained from canopy level. Although moisture content of vegetation can be influential to the radiant flux reflected from leaf-level, it may not be very straightforward to obtain the spectral characteristics that are directly related to the level of canopy moisture content. Canopy spectra form forest stands can be varied by structural variables (such as LAt, percent coverage, and biomass) other than canopy moisture content.

"파이돈" 102d10-107b10에서 제시되는 영혼 불멸에 대한 마지막 증명은 많은 논란의 대상이 되어왔다. 마지막 증명에서 소크라테스는 더 세련된 원인의 유형을 확립한 다음, 영혼이 몸에 삶을 가져오는 세련된 원인임을 보임으로써 영혼의 불사와 불멸을 증명하려 시도한다. 그런데 세련된 원인을 확립하는 과정에서 예로서 제시되고 있는 것들, 즉 셋, 불, 눈, 그리고 영혼의 존재론적 지위에 관해 치열한 논쟁이 있어왔다. 이 글에서는 이 논쟁의 주요 측면들을 면밀히 검토하고, 그것이 마지막 증명의 타당성에 어떤 영향을 미치는가를 고찰한다. 일군의 학자들은 저 넷이 모두 내재적 형상이라고 해석한다. 반면 일군의 학자들은 저 넷 모두가 내재적 형상이 아니라고 해석한다. 이 글에서는 저 넷 중에는 형상과 형상 아닌 것이 혼재하고 있음을 보인다. 그리고 궁극적으로 이러한 혼재와 영혼의 존재론적 지위가 모호한 상태로 남겨져 있다는 사실이 마지막 증명의 효력을 약화시키고 있음을 보인다.

Herein, we explored the potential of the apple's core microbiota for biological control of Erwinia amylovora, which causes fire blight disease, and analyzed the structure of the apple's bacterial community across different tissues and seasons. Network analysis results showed distinct differences in bacterial community composition between the endosphere and rhizosphere of healthy apples, and eight taxa were identified as negatively correlated with E. amylovora, indicating their potential key role in a new control strategy against the pathogen. This study highlights the critical role of the apple's bacterial community in disease control and provides a new direction for future research in apple production. In addition, the findings suggest that using the composition of the apple's core taxa as a biological control strategy could be an effective alternative to traditional chemical control methods, which have been proven futile and environmentally harmful.

Objectives : This paper aims to analyze the origins of the pathogenic qi[邪氣] concept through analysis of related character shapes and examples within the Mawangdui Yishu, where we can grasp the state of medicine pre-Huangdineijing. Methods : Etymology was determined through ancient character analysis, while examples of its usage and original texts were compared to extract their implications. For usage analysis, medical texts of later periods that contained similar verses or contents with the Mawangdui text were compared, through which similarities and changes in meaning of the word or verse were examined. Conclusions : While the term 'xieqi(邪氣, pathogenic qi)' had not yet been mentioned in the Mawangdui text, 'eqi(惡氣)' was used similarly. Wind[風], cold[寒], dampness[濕] were not only understood as terms referring to weather or climate but possible causes for disease. Meanwhile, there was lingering belief from the Shang(商) period that saw disease as God's punishment, which could be seen as transition phenomenon from superstition to rational thought. Through diseases 'wind disease[風病]' and 'bi(痹)', we could determine that medicine at the time was limited to the Yin-yang theory, having not yet integrated the Five phases perspective. Moreover, the possibility of other pathogenic qi elements, 'heat[暑]', 'dryness[燥]', and 'fire[火]' could be assumed to have been embedded in 'wenbing(溫病)'.
