목장에서 사육가축의 건강관리를 위해서는 빠른 응급치료가 중요하다. 그러나 목장에서 자가치료 시, 치료에 관한 잘못된 상식이나 약물처치로 인해 회복가능한 환축이 폐사하는 경우를 접하는 경우가 있다. 목장에서 환축 발생시 치료율을 높일 수 있는 응급처치에 대해 소개하고, 자가치료 시 흔히 범할 수 있는 실수에 관해 사례를 중심으로 논의하고자 한다.

This study focused on the introduction of processing procedure for microcapsules loaded with the healing agent and then microcapsules with the healing agent were manufactured by experiments. The DCPD (dicyclopentadiene) was used for the healing agent and the shell of microcapsules was consisted of urea-formaldehyde resin. The magnitude and the site distribution of microcapsules were measured by a particle size analyzer using laser diffraction technique. Thermal analysis was conducted by using a DSC fur the healing agent, microcapsules without the healing agent, and microcapsules with the healing agent. Also thermal stability was investigated by using a TGA under continuous and isothermal heating conditions far the healing agent, microcapsules without the healing agent, microcapsules with the healing agent. According to the results. microcapsules with the healing agent were verified to be so thermally stable that the healing agent could not evaporate until the shell of microcapsules were burned.

This study investigated the thermal stability of Grubbs' catalyst and its reactivity with self-healing agents for self-healing damage repair. Four types of Grubbs' catalyst supplied by manufacturers were considered and each catalyst was tested in as-received and grinded conditions. Four types of self-healing agents were prepared by varying the mixing ratio of dicyclopentadiene (DCPD) and 5-ethylidene-2-norbonene (ENB). Heat flows as a function of temperature were measured through a differential scanning calorimetry (DSC) to determine the thermal stability of catalysts. Reaction heats of self-healing agents with the catalyst were measured to evaluate the reactivity of the catalyst. For this evaluation, Fluka Chemika Grubbs' catalyst was used based on the maximum temperature and the time to reach the maximum temperature. According to the results, catalysts had different shapes depending on the manufacturer and the results showed that the smaller the size of the catalyst the higher the reactivity with self-healing agents. As the ENB ratio in self-healing agents increased, the maximum temperature increased, and the time to reach the maximum temperature decreased. As the amount of the catalyst increased, the maximum temperature increased, and the time to reach the maximum temperature decreased. Considering the thermal stability of the catalyst and its reactivity with the self-healing agent, combination of 0.5 wt% catalyst and the D3E1 self-healing agent was optimal for self-healing damage repair. Finally, as the thermal decomposition may occur depending on the environmental temperature, the catalyst must not be exposed to temperature higher than that is necessary to maintain the thermal stability of the catalyst.

최근에 스포츠 손상이 증가하고 관절경을 이용한 치료가 발전하면서 조기에 더 적극적인 치료를 하는 추세이다. 또한 방사선 소견에 비하여 관절경하에서는 연골이 불안정하거나 분리되어 있는 경우도 있으므로 기존의 수술 적응증보다는 좀 더 광범위하게 관절경 검사 및 수술적 치료가 요구된다고 생각한다. 치료 방법을 하면 $1.5cm^2$ 이하의 병변을 가진 50세 이하의 환자는 관절경을 이용하여 변연 절제술, 연골하 천공, 연마, 미세 골절술, 소파술 등의 방법으로 치료할 수 있다. 같은 방법으로 50세 이상의 $3cm^2$ 이하의 병변을 가진 환자 중 mosaicplasty와 자가 연골 세포 이식술을 적용할 수 없는 환자에서 시도해볼 수 있다. $1.5\sim3cm^2$의 병변을 가진 50세 이하의 환자, 그전의 관절경적 치료로 실패한 경우에는 자가골 연골 이식 또는 자가 연골 세포 이식술을 이용하여 치료해야 한다. $3cm^2$ 이상의 병변을 가진 50세 이하의 환자는 자가 연골 세포 이식술이나 동종 골 연골 이식을 이용하여 치료하며, 50세 이상의 환자는 관절 고정술이나 족근 관절 인공치환술을 고려하는 것이 바람직하다.

This study investigated the agents for self-healing system that could be developed to prevent UST(underground storage tank) from leaking. The system involves short range wireless communication to locate a leakage. Four commercially available silicons are arbitrarily chosen to evaluate suitability as a self-healing agent through a series of laboratory experiments. finally the experiments are simulated using computational Fluid Dynamic Program.

The purpose of this study is to determine whether impact of event and health beliefs affect adherence to self-care guidelines in the general public. The participants were 331 adults living in the Daegu/Gyeongbuk region. Data were collected using an online survey. The collected data were analyzed using hierarchical regression analysis and Process Procedure (Model 4). The results reported impact of event had a significant direct effect on health beliefs, and health beliefs had a significant direct effect on adherence to self-care guidelines. Also, the mediating effect of health beliefs on the relationship between impact of event and adherence to self-care guidelines was significant. To facilitate health education among the general public, it is necessary to include educational content to establish health beliefs regarding novel diseases such as COVID-19.

구강안면 동통중 가장 대표적인 측두하악장애를 치료하는데 있어 전기침 자극요법이 갖는 임상적 치료효과를 평가하기 위하여 측두하악장애 환자군을 환자에 대한 교육 및 온습포를 시행하는 자가치료 환자군, 전기침 자극요법을 시행하는 전기침 자극 환자군, 교합안정장치를 장착하는 구강내 장치장착 환자군, 총 3군으로 구분하였다. 이들 환자군에서 치료전과 치료 1주후 및 1개월 후에 visual analogue scale을 이용한 동통의 정도와 두경부의 근육촉진지수, 하악의 기능이상지수 및 저작근들의 압력통각역치를 측정하여 다음과 같은 결과를 얻었다. 1. 자가치료 환자군의 1주일 치료후 동통정도, 근육촉진지수 및 기능이상지수가 유의하게 감소되었다. 2. 전기침 자극환자군은 1주일 치료후 동통의 정도가 유의하게 감소하였으면 1개월 치료 후 동통의 정도와 근육촉진지수가 유의하게 감소되었다. 3. 구강내 장치장착환자군은 1주일 치료 후 동통의 정도가 유의하게 감소하고 심부교근의 압력통각역치가 유의하게 감소하였고 심부교근의 압력통각역치가 유의하게 증가되었다.

Purpose: Aroma therapy is one modality of alternative medicine. It was well known to have an analgesic, antidepressive and anxiolytic effects. This study is designed to investigate the effect of aroma self hand massage on vital signs, pain, depression, anxiety and stress in breast cancer patients. Methods: 32 female patient over 20 years old were divided into two groups by a non-blinded randomized controlled method. Patient in the aroma group (n=15) massaged their hands twice a day using aroma oil by themselves in their home for 2 weeks. However, those in control group (n=17) had not received my intervention during the study periods. Pain intensity, state anxiety, depression and stress of subjects were evaluated three times (0, 1, 3 weeks) using Visual Analogue Scale (VAS, $0{\sim}10cm$), State Trait Anxiety Inventory (STAI), Beck Depression Inventory Scales (BDIS), Brief Encounter Psychosocial Instrument (BEPSI revised edition). Also the change of patients' accompanying symptoms after aroma massage were analyzed using a structured questionnaire. Results: Pain Intensity decreased in the aroma group compared with control group (VAS changes $-0.83{\pm}1.01\;vs\;0.38{\pm}0.86$, P=0.005). The numbers of accompanying symptoms (P=0.044), depression score (P=0.001) and anxiety score (P=0.008) were significantly decreased in the aroma group, while in control group they increased after 2 weeks. However, the stress score showed no significant changes in both groups ($0.05{\pm}0.85\;vs\;0.04{\pm}0.20$, P=0.1519). The depression, anxiety and stress score showed negative correlation with compliance of aroma massage, but statistically no significant. The systolic blood pressure was a little increased in aroma group ($4.53{\pm}14.43\;vs\;0.0{\pm}7.22$, P=0.026), but was not significant clinically. Patients in the aroma group complained of several symptoms such as headache (20%), paresthesia (6.75%) and nausea (6.7%). However, there were no drop-out patients for those side effects. Conclusion: Aroma self massage during two weeks in breast cancer patients alleviates the pain intensity, depression and anxiety significantly.

Microcapsules of two different self-healing agents, 5-ethylidene-2-norbornene (ENB) and ENB with a crosslinker, surrounded by a melamine-urea-formaldehyde shell were manufactured. In this work, a red dye was incorporated into the self-healing agents as a tracer for better visual observations. It revealed that the incorporation of a red dye into self-healing agents did not disturb the formation of microcapsules from the examination of thermal resistance, particle size/size distribution and morphology of the resulting microcapsules. Releasing of self-healing liquid into the induced crack from ruptured microcapsules and filling between crack planes were observed using an optical microscope. Also observed was the reaction of filled healing agent with embedded Grubbs' catalyst in an epoxy coating layer.
