Background: For standardizing of Han-Yeol [寒熱], which is a kind of diagnosis method in oriental medicine, it is necessary to investigate into relationship of symptoms and signs representative of Han-Yeol [寒熱] to the biofunctional medical signals; thermal temperature by Thermography, Pulse-Respiration Ratio and so on. By correlation analysis of these data items acquired from patients, it could be provides the fundamental data for standardizing of Han-Yeol [寒熱]. Objectives: We performed this study to check the characteristics of thermal temperature with Han-Yeol [寒熱] statue by pulse-respiration ratio. Methods: We selected nine regions around acupoints including Yin dang[印堂], Sugu[水溝, GV26], Ch'ondol[天突, CV22], Chonjung[CV17], Chung-wan[中脘, CV12], Chonchu[天樞 S25], No-gung[勞官, P8], and calculated based on the utility of R.O.I.(Region of Integer) by IR-2000 these points temperature from 68 subjects. In practicing pulse-respiration ratio over 4.0 means the statues of Yeol [熱], pulse-respiration ratio below 4.0 means the statues of Han [寒]. To optimum conditions thermal temperature, which are not effected by internal and external variables, we studied preceding research. The results shows that optimal time period is 20minutes after undressed and the optimal region is the region around acupoints including Sugu [水溝, GV26]. Based on a preceding research results, we analyzed these data by Paired T-test between GV26 Region and 8-Thermography Regions and two-way repeated ANOVA with thermography$({\Delta}T)$ and Han-Yeol [寒熱] statue by pulse-respiration ratio. Results: 1. In applying of two-way repeated ANOVA with thermography$({\Delta}T)$ and Han-Yeol [寒熱] statue by pulse-respiration ratio, Sugu [水溝穴, GV26] - [印堂穴, HN1], Sugu 水溝, GV26] - Chonjung[CV17], Sugu [水溝, GV26] -Chung-wan[中脘, CV12]had significant differences. 2. In applying of Paired T-test between Sugu [水溝穴, GV26] Region and 8- Thermography Regions, there were significant differences except of Sugu [水溝穴, GV26] -Chondolp[天突, CV22]. 3. In the difference of Sugu [水溝, GV26] -Chung-wan[中脘, CV12], thermal temperature increases a lot in the statues of Yeol [熱], thermal temperature decreases a lot in the statues of Han [寒]. Conclusions: On the analysis of Thermography, we obtain the measurement conditions were considered the individual variations. And it is different that the thermal temperature change on Thermography according to Han-Yeol [寒熱] statue by pulse-respiration ratio.

Face detection algorithm of OpenCV recognizes the faces by Haar matching between input image and Haar features which are learned through a set of training images consisting of many front faces. Therefore the face detection method by Haar matching yields a high face detection rate for the front faces but not in the case of the pan and deformed faces. On the assumption that distributional characteristics of color histogram is similar even if deformed or side faces, a face detection method using the histogram pattern matching is proposed in this paper. In the case of the missed detection and false detection caused by Haar matching, the proposed face detection algorithm applies the histogram pattern matching with the correct detected face area of the previous frame so that the face region with the most similar histogram distribution is determined. The experiment for evaluating the face detection performance reveals that the face detection rate was enhanced about 8% than the conventional method.

The moxibustion therapy of orient medical is well known. Moxibustion method is used to burning moxibustion. The variation factors of the moxibustion stimulation for body can be applied to the electronic moxibustion method. This study is to analyze and examine the electroencephalogram(EEG) variations for moxibustion stimulation. In experiment, we divided six healthy male subjects into two same sized groups : with and without stimuli. The given stimuli are the moxibustion for CV4(Kwan-Won), CV8(Shin-Guel), and CV12(Jung-wan) acupuncture points. We have analyzed the power spectrum for ${\alpha}$, ${\beta}$, ${\delta}$, ${\Theta}$ waves and the average EEG variation level and each channels variation level of EEG. The result was that the moxibustion stimulation decreased the EEG levels of parietal lobe(ch 2, 3, 6, 7) according to the somatosensory system. And the apparent different points are that mild-heat($42{\sim}44^{\circ}C$) stimulation generating ${\alpha}$-wave is increased and ${\beta}$-wave is decreased, also slight-hot($45{\sim}48^{\circ}C$) stimulation made ${\alpha}$-wave decrease and ${\beta}$-wave increase for occipital lobe(ch 4,8) on the simulation group.

The present study describes carbohydrate metabolism, macro-element utilization and antioxidant defenses in response to an ozone dose (100 ppb, 8d) in two rice varieties. Tolerant (cv. Jinpumbyeo) and sensitive (cv. Chucheongbyeo) varieties of rice were grown in growth chamber for 30 days after sowing. Concentrations of chloroplast pigments and non-structural carbohydrates as well as activity of antioxidant enzymes were determined to evaluate the resistance against ozone stress. Ozone caused the decrease in chlorophyll a and carotenoid contents, and also resulted in faster decomposition of non-structural carbohydrate in leaf blade and leaf sheath. The contents of nitrogen and potassium in leaves were visibly decreased in cv. Chucheongbyeo with an increase in ozone exposure, but not in cv. Jinpumbyeo. Enzymatic antioxidants against ROS in both varieties responded in the order of POD, SOD and CAT, and their capacity was stronger in cv. Jinpumbyeo.

To layout the pattern in ecological and productive traits of sunflower (Helianthus annuus L.), two cultivars, Peredovic and Gunpo-local, were grown at 6 planting dates from May 15 to July 25 by 20 day intervals. Delaying of planting dates, Cv. Peredovic showed less variation in days to reach the head-visible stage than Cv. Gunpo-local. and two varieties are different in photosensitivity. Plant height and stem diameter and number of leaves of Cv. Gunpo-local were greater than those of Cv. Peredovic at the early planting, but the differences were decreased as planting were delayed. Cv. Peredovic yielded 158kg achences per 10are relatively from the May 5's planting. However delaying of planting dates after July 5, there was serious reduction in the yield.

In 2007, the first domestic pet insurance policies were introduced, and by 2023, numerous insurance products had been developed. The pet insurance market has been expanding steadily. However, as of 2022, only 0.8% of all pet owners have subscribed to pet insurance. Pet owners hesitate to enroll in pet insurance due to expensive premiums, unclear coverage details, and strict enrollment criteria. This paper proposes a model capable of detecting pet eye diseases and predicting their health age. Initially, EfficientNet is employed to identify the pet's eye disease, while OpenCV is utilized to locate and measure the size of the disease, enabling the calculation of the pet's healthy age. By leveraging the calculated health age, the aim is to aid insurance companies in determining pet insurance premiums. This model can facilitate the calculation of reasonable pet insurance rates based on the pet's eye condition and health age. Ultimately, the objective is to implement a system capable of detecting pet eye conditions and predicting their health age.

Sequence comparison of the RNA-dependent RNA polymerase of human caliciviruses (HuCVs) from Korean children with gastroenteritis revealed significant genetic variation among them. cDNA clones were produced from the HuCVs collected from pediatric population during a period of 1987-1994. The application of reverse transcription-polymerase chain reaction (RT-PCR) using primers directed to the RNA-dependent RNA polymerase region within ORF1 of Norwalk virus (NV) showed that 13.7% of HuCVs yielded PCR products of similar size to the NV prototype, NV8FIIa/68/US, with exceptions of HuCV 185/87/Korea and HuCV 1115/90/Korea. Computer analyses showed that the PCR products had a continuous protein encoding frame on the positive strand, and contained GLPSG and YGDD amino acid motifs at the predicted distance from primers. Alignment of the amino acid sequences of HuCVs with previously published sequences for Snow Mountain agent (SMA), NV, and Sapporo/82/Japan indicated that these strains can be divided into four major genogroups. There were 10 (45%) SMA-like CVs, one (4.5%) NV-like HuCVs, two (9%) Sapporo-like HuCVs, and nine (41%) unidentified HuCVs. This fourth genogroup should be investigated further. HuCV 185/87/Korea and HuCV 1115/90/Korea, Sapporo-like CVs, were genetically distinct from previously characterized HuCVs and more closely related to known animal CVs. One of the animal CV-like strain, HuCV 185/87/Korea, showed nucleotide and amino acid homology of only 67% and 73% with the prototype Sapporo/82/Japan. Further characterization of animal and human CV genomes and studies of possible cross-transmission of CVs from animals to humans are likely to be beneficial in understanding the epidemiology of HuCVs.

BACKGROUND: Recently, weather disasters such as hail and typhoon occur frequently. These threaten the stable cultivation of potatoes. It is very important to cultivate potatoes with stable under unexpected weather disasters. This study was performed to investigate the correlation between mophological characteristics of potato stem and its resistance to hail damage in different potato cultivars. METHODS AND RESULTS: Hail fall occurred for 8 minutes on May 31, 2012 in the field of Highland Agriculture Research Center located in Jinbu-myeon Gangwon-do. Potato crop grown in the field was affected by hail due to which the stems of potato were broken. The percentage of broken stem of potato was investigated as the level of damage by hail. To determine the difference in the ratio of broken stem among the potato cultivars, physical characteristics of potato stem such as diameter and hardness were measured. To evaluate recovery phase after hail damage, ground coverage and yield were measured. The percentage of broken stem of cv. Goun and cv. Saebong were 30%, 26%, respectively, whereas it was 5% in the cv. Atlantic. Damage by hail was the lowest in cv. Atlantic. Diameter of the stem was 15 mm in cv. Atlantic, 13 mm in cv. Goun and 11 mm in cv. Saebong. The hardness of potato cultivars was measured which was 74 N in cv. Atlantic. 71 N in cv. Goun and 59 N in cv. Saebong. The ground coverage in cv. Atlantic was 79%, which was the highest followed by 73% in cv. Saebong and 56% in cv. Goun. The yield of cv. Atlantic was monitored at 90 days after planting which was 40 MT/ha and that of cv. Saebong was 36 MT/ha, whereas in cv. Goun, it was 30 MT/ha which was the lowest. CONCLUSION: The ratio of broken stem in cv. Atlantic was the lowest compared to cultivars. In the physical characteristics of stem, cv. Atlantic was the highest in value of diameter and hardness. Based on these results, it was considered that cv. Atlantic was resistant to hail damage compared to other cultivars.

A method isolating Populus euramericana cv. I-214 mesophyll protoplasts was developed to facilitate application of genetic engineering techniques to this species. The suitable medium for shoot multiplication in vitro was MS basal medium with $0.1mg/{\ell}$ BAP. The effects of several factors influencing protoplast isolation could be evaluated quickly by using leaf in vitro and known volumes of maceration and washing media. The best yields of mesophyll protoplasts were obtained using leaves in vitro in 2.0% Cellulase R-10, 0.8% Macerozyme R-10, 1.2% Hemicellulase, 2.0% Driselase, 0.05% Pectolyase Y-23, and O.6M Mannitol in addition to DTT and MES buffer adjusted to pH 5.6. Over $2.4{\times}10^6$ protoplasts per gram of leaf were produced using these conditions. For protoplast purification, the most favorable sucrose concentration of floating solution was 0.6M after washing them with CPW solution. This method of screening factors affecting protoplast isolation could be applicable to other species.
