A Literatur Review of Physical and Breathing Exercises for Ear Health, the results were as follows. 1. The most common using way is rubbing your ears and auricle with warm palms. 2. To stimulate inner acoustic meatus, obstruct external acoustic meatus for a short time by the palm or fingers and then to stimulate it by the sudden opening. 3. This method is a common way to press aurical or orifice of external acoustic meatus for example, TE21(耳門), TE20(角孫), GB2(聽會), TE19(노息), TE18(계脈), GB11(竅陰), TE17(예風) etc. 4. The best time to pratice is early in the morning or before go to bed, but a litter difference by the writer's opinion, so there is not consistency. 5. Since tinnitus and hardness of hearing is related to the who1e body, it is known that you can relax your whole body by pressing the acupuncture points located in the head of occipital region or by stretching the upper half of the body. 6. There is method that obstruct your ears with palms and 3rd finger on your occipital region and splash by the 2th fingers.(sound the celestial drum)

Objectives: Previous studies have shown that anger can lead to frontal lobe α (8-13 Hz) band asymmetry (FAA) in electroencephalogram (EEG), in accordance with motivational direction. This pilot study aimed to investigate the impact of acupuncture on FAA elicited by anger. Methods: Thirty-four right-handed participants scoring above 75 points on the Novaco Anger Scale were included. Baseline EEG signals were recorded for eight minutes using a 32-channel cap under comfortable conditions. Anger was induced through a nine-minute sequence of Articulated Thoughts in Simulated Situations (ATSS) task. Following that, participants received acupuncture at GB20 and GB21 for 10 minutes. Fast Fourier transform was employed for frequency analysis, and repeated measure ANOVA was conducted for statistical analysis. Results: The results revealed that participants exhibited significantly higher FAA (p = 0.026), particularly in the left hemisphere, after the ATSS task sequence compared to the baseline. During acupuncture treatment, the greater left-sided FAA was significantly reduced (p = 0.027) and reversed. Upon the cessation of acupuncture, FAA returned to a value between the baseline and the anger-evoked stage (p = 0.046). Conclusion: The EEG results of this study revealed that anger stimulation induced an increase in left-sided FAA, which was effectively alleviated by acupuncture. This led to an immediate restoration of FAA asymmetry induced by anger. These findings suggest the potential of acupuncture as a treatment option for reducing FAA associated with anger.

We introduces a system that enables fast and effective visualization of natural disaster data such as typhoons, tsunamis, floods, and flooding to help make informed decisions in disaster situations. Data containing disaster information consists of a few hundred megabytes to many tens and hundreds of gigabytes, which can not be handled by a PC. This system was implemented in the form of a client-server based service to generate and output results from high-performance servers. The server in a built-in, high-performance cluster handles client requests and sends the result of visualization to the client. Clients can receive the results in any form of images, videos, or 3D graphic model by specifying a desired time frame, effectively viewing the results with a user-friendly GUI.

Risk management system should be able to support a decision making within a short time to analyze stream data in real time. Many analytical systems consist of CPU computation and disk based database. However, it is more problematic when existing system analyzes stream data in real time. Stream data has various production periods from 1ms to 1 hour, 1day. One sensor generates small data but tens of thousands sensors generate huge amount of data. If hundreds of thousands sensors generate 1GB data per second, CPU based system cannot analyze the data in real time. For this reason, it requires fast processing speed and scalability for analyze stream data. In this paper, we present a fast visualization technique that consists of hybrid database and GPU computation. In order to evaluate our technique, we demonstrate a visual analytics system that analyzes pipeline leak using sensor and tweet data.

Distribution changes in microalgae communities were studied in the Nakdonggang River at two sampling stations (St.1 Gyeongcheongyo Bridge (GB) and St.2 Daedong Wharf (DW)) at monthly intervals from January 2021 to November 2021. A total of 83 taxa included 82 species, 1 forma, belonging to 49 genera, 32 families, 21 orders, and 8 classes. The most important groups were Bacillariophyta and Chlorophyta. The number of species ranged from 5 to 24 in GB, and from 9 to 21 taxa in DW. The contribution of Bacillariophyta to the total species richness was the highest during all survey periods, and Chlorophyta yielded the next highest value in the study area. The dominant taxa were Aulacoseira ambigua, A. ambigua f. japonica, and Ulnaria acus in this study. Cluster analysis and non-metric multidimensional scaling (nMDS) analysis based on Bray- Curtis similarity identified 4 major groups, which corresponded to microalgae assemblages and their characteristic species. Correlation was analyzed through the CCA analysis. It was found that there was a correlation between the microalgae and environmental factors. It was revealed that the divided groups were distinguished because of the differences by the survey period. Therefore, seasonal change was judged as a major factor affecting the distribution of microalgae communities.

Objective: In order to find oriental medical therapies on Parkinson's disease and to make a fundamental basis for clinical application, this study was performed. Methods: We reviewed 35 kinds of the ancient and modern text, and related articles. Results: Parkinson's disease is an extrapyramidal disease characterized by akinesia, tremor at rest, rigidity, and slowness of movement. In old oriental medical text, Parkinson's disease is described as Jinjeon(振顫), Chi, Gyeong (痙), Gyejong, Ryeon(攣) and Pyeongo(偏枯), Tantan, Jungbu(中腑症) of Jungpung(中風). According to the text, major pathological causes were Wind(風), Fire(火), Phlegm(痰), and Blood stasis(瘀血). And Parkinson's disease can be classified into four clinical types as liver & kidney yin-deficiency, qi & blood deficiency, retention of phlegm-heat, and qi-stagnation & blood stasis. Standardized acupuncture points are GV20, GB20, GV14 on head, CV12, ST25 on abdomen, GV26, ST7, GB1, S14, LI20 on face, LI4, LI11, TE5, SI3, HT3, LI15, SI6 on upper extremity, and ST36, GB34, SP6, LR3, KI1, GB30, BL40 on lower extremity. Other methods, such as scalp acupuncture, electro-acupuncture, and herb-acupuncture, can be applied to treat Parkinson's disease. Conclusions: We find out that there are oriental medical concepts related with Parkinson's disease such as Jinjeon(振顫), Chi, Gyeong (痙), Gyejong, Ryeon(攣) and Pyeongo(偏枯), Tantan, Jungbu(中腑症) of Jungpung(中風), of which major causes are Wind(風), Fire(火), Phlegm(痰), and Blood stasis(瘀血). We can also apply many effective acupuncture points and acupuncture therapies according to differential diagnosis, for example, liver & kidney yin-deficiency. qi & blood deficiency, retention of phlegm-heat, and qi-stagnation & blood stasis.

This paper describes a CMOS 16:1 binary-tree multiplexer(MUX) using $0.18-{\mu}m$ technology. To provide immunity for wide frequency range and process-and-temperature variations, the MUX adopts several delay compensation techniques. Simulation results show that the proposed MUX maintains the setup margins and hold margins close to the optimal value, i.e., 0.5UI, in wide frequency-range and in wide process-and-temperature variations, with standard deviation of 0.05UI approximately. These results represent that these proposed delay compensations are effective and the reliability is much improved although CMOS logic circuits are sensitive to those variations. The MUX is fabricated using $0.18-{\mu}m$ CMOS process, and tested with a test board. At power supply voltage of 1.8-V, maximum data-rate and area of the MUX is 1.65-Gb/s and 0.858 $mm^2$, respectively. The MUX dissipates a power of 24.12 mW, and output eye opening is 272.53 mV, 266.55 ps at 1.65-Gb/s operation.

Objectives : The objective of this study is to apply the contents of "WaHyul(訛穴 : The errors of acupoint locations"of "ChimGuKyungHumBang" to modern acupoint locations. Methods : The text of "WaHyul" was closely examined and analyzed. "WHO standard acupuncture point locations in the western pacific region" was reviewed based on its contents. Results : According to the analysis, the correct 少商(LU11) was mentioned as a spot appropriately distanced from the corner of the nail root under the skin. This is the most accurate and reasonable synthesis of other related texts. Furthermore, the necessity of defining the locations of all the well points was also emphasized and their locations were mentioned that could be located by the same method. There is no further discussion of other acupoints apart from descriptions of their locations from other texts. Some parts that were pointed out as common errors included not only commonly made mistakes, but errors made in acupuncture texts as were true for 神門(HT7) and 肩井(GB21). The standards of 少商(LU11), 合谷(LI4) and 足三里(ST36) presented in the WHO Standardization are not only similar to what 「WaHyul」 indicated as errors in acupoint locations, but also deviate other acupuncture texts; appropriate corrections must be made. The standard of 肩井(GB21) presents a new acupoint locating method never mentioned before in received classic acupuncture texts and so a rediscussion is in need. Other standards, such as the 絶骨(GB39), had some points of controversy, yet somewhat incomplete while HT7 did not go beyond the bounds of "WaHyul". Conclusions : "WaHyul" can be used to revise WHO standards, and has practical value in modern acupoint locating.
