Objectives : This study investigated the current utilization status of thermotherapy devices in Korean medicine (KM) institutions and identified areas for improvement and further development, as perceived by KM doctors (KMDs). Methods : An online survey was conducted, targeting KMDs primarily engaged in clinical patient care. The questionnaire included items about respondents' clinical practices, the extent of thermotherapy device usage, their opinions on these devices, and perceived improvement needs. The collected data underwent quantitative analysis. Results : From the 1,025 respondents, data from 862 respondents who provided complete responses were analyzed. On average, respondents utilized thermotherapy treatments for 80% of their patients. Infrared (IR) phototherapy unit, electrical moxibustion apparatus, and heater-based thermotherapy devices were predominantly owned by respondents, with IR being the most frequently used. The average satisfaction score for current thermotherapy devices was 79. A significant concern raised was the necessity for improved health insurance coverage and efficacy evaluation. Conclusions : This research has confirmed that the extensive use of thermotherapy devices by KMDs in treating primarily musculoskeletal and gastrointestinal ailments - common conditions among patients in KM institutions. The main areas identified for improvement encompass safety, cost-effectiveness, and device efficacy. Future enhancements in thermotherapy devices should address these crucial aspects.

Objective: The aim of this study was to analyze kinetic variables between thermotherapy and dynamic warm-up during drop-landing. Method: Twenty male healthy subjects (Age: 21.85 ± 1.90 years, Height: 1.81 ± 0.06 cm, Weight: 68.5 ± 7.06 kg) underwent three treatments applied on the thermotherapy of femoral muscles and a dynamic warm-up. The thermotherapy was performed for 15 minutes while sitting in a chair using an electric heating pad equipped with a temperature control device. Dynamic warm-up performed 14 exercise, a non-treatment was sitting in a chair for 15 minutes. Core temperature measurements of all subjects were performed before landing at a height of 50 cm. During drop-landing, core temperature, joint angle, moment, work of the sagittal plane was collected and analyzed. All analyses were performed with SPSS 21.0 and for repeated measured ANOVA and Post-hoc was Bonferroni. Results: Results indicated that Thermotherapy was increased temperature than other treatments (p = .000). During drop-landing, hip joint of dynamic warm-up was slower for angular velocity (p < .005), and left ankle joint was fastest than other treatments (p = .004). Maximum joint moment of dynamic warm-up was smaller for three joints (hip extension: p = .000; knee flexion/extension: p = .001/.000; ankle plantarflexion: p = .000). Negative work of dynamic warm-up was smaller than other treatments (p = .000). Conclusion: In conclusion, the thermotherapy in the local area doesn't affect the eccentric contraction of the thigh. The dynamic warm-up treatment minimized the joint moment and negative work of the lower joint during an eccentric contraction, it was confirmed that more active movement was performed than other treatment methods.

This research attempts to develop a method to relieve dysmenorrhea, which is an obstacle to many women's social activities, by designing a smartwear with built-in thermotherapy and TENS device. TENS therapy has the advantages of being controlled by patients and not depending on the use of drugs. The TENS device is designed as a stomach band so as to be unnoticeable to others when outer clothes are worn; the size was minimized and attached to underwear to facilitate use everywhere at any time. A current problem is the limitation of minimizing, but as battery technology is further developed, we can anticipate much smaller devices. The development of aforementioned smartwear function will increase women's choices in occupations and general improvement in quality of life.

This study aims to develop an electronic moxibustion device for the quantification of moxibustion, which progresses a critical role in traditional oriental medicine as well as to assess the characteristics of heating. The assessment revealed that the proposed electronic moxibustion treatment device can reduce the time required for reaching the desired heat level and continue to provide heat consistently. Moreover, heat transmitted to the treated area was found to correspond to a heating pattern of the proposed electronic moxibustion device. It proved both quantitative control and safe treatment for the proposed electronic moxibustion device.

The purpose of this study, the wearing conditions of functional pressure clothing applied with the thermotherapy device were determined by three types (NW, CW, TCW) and the difference in isokinetic strength, muscle activity around the forearm was investigated and the effects of products mixed with thermotherapy and pressure treatment were verified. Ten men in their 20s were selected as subjects, and all subjects were randomly assigned three wearing conditions, and wrist flexion/extension exercise was performed at 30° and 90° angular velocity in isokinetic equipment. Peak torque, average power, and EMG were measured during exercise in all conditions. For peak torque, CW was significantly highest at velocity of 30°/sec flexion. Average power showed no significant difference by condition. In the angular velocity of 90°/sec, flexion was significantly higher in CW and TCW than in NW. As a result, wearing clothes with pressure effect and heat effect can show high efficiency in high muscle strength development and fast contraction activity during low speed exercise, and it is thought that it can show improvement of exercise ability through efficient recruitment of motor unit.

Objectives : This study aimed to investigate temperature characteristics by heat transfer type of therapeutic modalities. Methods : We selected heating and cooling modalities that are frequently used in clinical by heat transfer type: conduction, convection, radiation, and conversion. We used ham as tissue model, and applied the modalities for 30 minutes. We measured real-time changed temperature($^{\circ}C$) of the surface, 2, 4, 6, 8, 10, 12, and 14 mm depth. Results : 1. In conduction-using hot pack, ice pack, and CryoStamp heating-cooling combination therapy unit($40^{\circ}C/{\sim}15^{\circ}C$), the surface temperature sharply rose close to equilibrium in first 5 minutes. 2. In convection-using smokeless moxa, temperature slowly rose to the maximum at 25-minute elapsed time. But in another convection-using CRAiS cryotherapy device, result was similar to that of conduction. 3. In radiation-using infrared lamp, result was similar to that of conduction, but not reached equilibrium during applying time. 4. In conversion-using ultrasound device, temperature was the highest at 6 mm depth, and not reached equilibrium during applying time. Conclusions : We could comprehend temperature characteristics and proper use of modalities by heat transfer type. It would be necessary to consider in vivo physical conditions in further studies.

Apples are the most grown fruit crops in the fruit industry of Korea. However, virus or viroid infection such as apple mosaic virus (ApMV), apple stem grooving capillovirus (ASGV), apple stem pitting virus (ASPV), apple chlorotic leaf spot virus (ACLSV), apple scar skin viroid (ASSVd) causes fruit yield reduction and poor fruit quality. Therefore, in this study, we examined to established an efficient virus-free system to eliminate the most infected ASGV virus in domestic apple orchard. We investigated that the shoot growth rate and the virus removal rate in ASGV infected potted apples that were treated with heat treatment in a growth chamber (constant temperature/humidity device) maintained at 36℃, 38℃ and 40℃ for 4 weeks. Here we found that the shoot growth rate was the highest in the heat treatment group (36℃) and the virus was removed in the middle and top of the shoot but not in the bottom. The virus was did not removed in the 38℃ and 40℃ heat treatment group in all section of shoots, and the heat treatment group (40℃) died after 4 weeks of heat treatment without growth of shoots. We performed in vivo shoot-tip grafting using the shoot-tip of potted apple heat-treated at 36 ℃, and we also investigated the viability and virus removal rate, which showed 94% viability and 20% virus removal rate. Collectively, our results suggest that it would be possible to produce the virus-free apple plants through heat treatment and shoot-tip grafting.
