This study evaluates the predictability of the number of days of heat and cold damages by growth stages of rice in South Korea using the hindcast data (1986~2020) produced by Pusan National University Coupled General Circulation Model-Weather Research and Forecasting (PNU CGCM-WRF) model chain. The predictability is accessed in terms of Root Mean Square Error (RMSE), Normalized Standardized Deviations (NSD), Hit Rate (HR) and Heidke Skill Score (HSS). For the purpose, the model predictability to produce the daily maximum and minimum temperatures, which are the variables used to define heat and cold damages for rice, are evaluated first. The result shows that most of the predictions starting the initial conditions from January to May (01RUN to 05RUN) have reasonable predictability, although it varies to some extent depending on the month at which integration starts. In particular, the ensemble average of 01RUN to 05RUN with equal weighting (ENS) has more reasonable predictability (RMSE is in the range of 1.2~2.6℃ and NSD is about 1.0) than individual RUNs. Accordingly, the regional patterns and characteristics of the predicted damages for rice due to excessive high- and low-temperatures are well captured by the model chain when compared with observation, particularly in regions where the damages occur frequently, in spite that hindcasted data somewhat overestimate the damages in terms of number of occurrence days. In ENS, the HR and HSS for heat (cold) damages in rice is in the ranges of 0.44~0.84 and 0.05~0.13 (0.58~0.81 and -0.01~0.10) by growth stage. Overall, it is concluded that the PNU CGCM-WRF chain of 01RUN~05RUN and ENS has reasonable capability to predict the heat and cold damages for rice in South Korea.

Objectives The purpose of this study was to examine the characteristics of diagnostic pattern questionnaire associated with Body Mass Index in premenopausal women. Methods We studied 41 patients visiting Gangdong Kyung Hee University Hospital from 1st April 2011 to 25th May 2011. The subjects were categorized in two groups, overweight & obesity group (n=12) and low weight & normal group (n=29). We studied the difference of diagnostic pattern questionnaire scores between two groups by Independent samples T-test and correlation between diagnostic pattern questionnaire scores of overweight & obesity group by Pearson's correlation coefficient test using SPSS for windows (version 13.0). Results Blood stasis, retention of undigested food, cold pattern scores of overweight & obesity group were non-significantly higher than low weight & normal group. Heat pattern score of overweight & obesity group was significantly higher than low weight & normal group. Cold-heat, phlegm-cold, blood stasis-cold, phlegm-blood stasis, phlegm-retention of undigested food significantly showed positive correlation coefficient in overweight & obesity group. Conclusions The results suggest that obese women tend to show heat pattern. It seems to be that multiple factors such as phlegm, blood stasis, retention of undigested food are causative of obesity.

Objectives : This study aims to evaluate the effects of expiration-to-inspiration time ratio (E/I-ratio) on heart rate, which represents cardiac autonomic function, and cold-heat in the healthy people. Methods : 49 healthy young volunteers(male : female = 32 : 17) were recruited in the study. The participants completed the questionnaire for yin-yang pattern identification and then we measured the chest plethysmogram for respiration signal and the electrocardiogram for NN intervals during different E/I-ratio from 1 to 2. We compared heart rate variability including RMS-SD, VLF, LF and HF, and the trend-cycle factors decomposed from NN interval data by time series analysis among the respective E/I-ratio. We also confirmed the difference on the trend-cycle factors according to the score of the questionnaire for cold and heat pattern identification. Results : There were differences on the trend-cycle factors from NN interval data, but no significant difference on heart rate variability, among the respective E/I-ratio. We also found significant relationship between the trend-cycle factors and the heat pattern identification scores. Conclusions : The results indicate that cardiac autonomic function can be modulated by the E/I-ratio and the modulation will be slower and more tendencious than respiratory sinus arrhythmia.

본 연구에서는 Pusan National University Coupled General Circulation Model-Weather Research and Forecasting (PNU CGCM-WRF)에서 생산된 hindcast 자료(1986~2020)를 이용하여 우리나라의 주요 곡물 중 하나인 콩의 생육단계별 고온해 및 저온해 발생일수의 예측성을 평가하였다. 예측성을 평가하는 방법으로는 Normalized Standard Deviations (NSD), Root Mean Square Error (RMSE), Hit Rate (HR), Heidke Skill Score (HSS)이다. 이를 위해 먼저 콩의 고온해 및 저온해를 정의하는 변수인 일 최고기온(Tmax) 및 일 최저기온(Tmin)의 모의성능을 검증하였다. 그 결과 1~5월(01RUN~05RUN)의 초기조건을 가지고 시작하는 월에 따라 다소 차이가 있지만, Variance Scaling 방법을 적용하여 보정한 결과가 보정전보다 관측과 유사하게 나타났으며, 보정한 3~10월의 Tmax 및 Tmin에 대한 모의성능은 전반적으로 01RUN~05RUN에 Simple Composite Method (SCM)을 적용하여 평균한 결과(ENS)에서 높게 나타났다. 또한, 콩의 생육시기별 고온해 및 저온해 발생일수의 지역적 패턴과 특성을 관측과 비교하였을 때 모형이 잘 모의하고 있다. ENS에서 콩의 고온해(저온해)에 대한 HR과 HSS는 생육시기 별로 0.45~0.75, 0.02~0.10(0.49~0.76, -0.04~0.11)의 범위를 가진다. 결론적으로, PNU CGCM-WRF chain의 01RUN~05RUN 및 ENS는 우리나라 콩의 생육시기별 고온해 및 저온해를 예측할 수 있는 성능을 가지고 있다.

Objectives : Cold hypersensitivity has been regarded to be associated with Autonomic Nervous System (ANS). This study aims to investigate the indicator of cold hypersensitivity of hands and evaluate the correlation between indicator of coldness of hands and Heart Rate Variability (HRV). Methods : We studied 55 patients with cold hypersensitivity of hands who visited in SeMyung University Hospital from 17 August 2015 to 21 August 2015. Thermometer and VAS scale were used for the diagnosis of cold hypersensitivity. After careful examination to rule out other disease which may affect thermometer and HRV data, patients were taken thermometer, those with thermal difference between upper arm (L4) and palm(P8), also asked to answer a VAS scale of cold hypersensitivity of hands, VAS more than 4 were enrolled for evaluation. Results : There was significant correlation between L4-P8 temperature difference and VAS score of cold hypersensitivity. In HRV data, normalized high frequency (HF normal) was significantly correlated with L4-P8 temperature difference, which was objective indicator of cold hypersensitivity of hands. Conclusions : L4-P8 temperature difference using thermometer is objective indicator of cold hypersensitivity, based on VAS scale. Cold hypersensitivity is highly related with ANS, regulating body heat and temperature. HRV is considered to be widely used in cold hypersensitivity in hands for evaluation of ANS.

Objectives This study was conducted to observe physiological changes when the function of spleen was extremely deteriorated, and to make an animal model with spleen deficiency. Methods The Normal group (Nr group) was not administered with Senna Folium extract. The SFE group(Senna Folium extract group) was administered with Senna Folium extract every day for the first 2 weeks and then every other day for another week. And the SFE_G group(Senna Folium extract_Ginseng group) was also administered with Senna Folium for 3weeks like the SFE group and fed with ginseng in the third week. Results The score of spleen deficiency was significantly higher in SFE group than in the Nr group and significantly lower in the SFE_G group than in the SFE group. The total weight gain was significantly lower in the SFE group than in the Nr group, and the average daily weight gain was significantly lower in the SFE group than in the Nr group. The difference in stool weight before and after the process of drying was significantly higher in the SFE group than in the Nr group, and significantly lower in the SFE-G group than the SFE group. There was no significant difference in the outcomes related to cold and heat among the three groups. Conclusions Through this study, the animal model with spleen deficiency was developed to prepare a stepping stone for animal tests to verify the efficacy and safety of constitutional prescriptions.

Objectives: The purpose of this study was to examine the relationship between pathological patterns and hyperventilation syndrome, using pathological pattern and Nijmegen questionnaires. Methods: 33 healthy adults were asked to complete the Cold-Heat-, Phlegm-, Yin deficiency, and Lao Juan (勞倦)-pattern questionnaires, the Chalder fatigue scale, and the Nijmegen questionnaire at Kyung Hee University Hospital. We performed Pearson correlation analyses between the pathological pattern questionnaires and the Nijmegen questionnaire. The questionnaires were composed of several factors. Therefore, each factor and Nijmegen questionnaire score were also analyzed. Results: All of the pattern questionnaire scores had a positive correlation with the Nijmegen questionnaire score. The phlegm pattern, in particular, and the LaoJuan (勞倦) questionnaire scores had high correlation coefficients. The coefficient for the phlegm pattern was 0.856 and the coefficient for the LaoJuan (勞倦) pattern questionnaire was 0.855. Conclusions: The results mean that the pathological pattern questionnaires could be one of the reference materials to evaluate hyperventilation syndrome. Furthermore, improvement of pathological patterns may be helpful for treating hyperventilation syndrome, together with conventional therapies including breathing training.

The purpose of this study is to research the degree of recognition & performance of traditional postpartal care for postpartal women and to provide the basic data for improvement of service in a postpartum care center. The respondents of this study were 100 women of 6 postpartum care centers within a C province from Oct. 20 to Dec. 10, 2000. The instruments of measure were used for collecting data on the degree of recognition & performance of traditional postpartal care developed by the researcher. Data analysis consisted of frequency, percentage, mean, standard deviation, paired t-test, t-test, ANOVA which are calculated by Scheffe test and Cronbach's alpha which is used as a reliance level by using a SPSS-PC+. The results of the study were as follows:1. The average score for the degree of recognition of traditional postpartal care(Sanhujori) for postpartal women was $3.09{\pm}.31$, and they recognized that it was important. The methods which were ranked were as follows; Protecting the body from a harmful state, invigorating the body by the argumentation of heat and avoidance of cold, handling with whole heart, and keeping clean, resting without working, eating well. 2. The average score for the degree of performance of traditional postpartal care (Sanhujori) for postpartal women was $2.81{\pm}.31$, and they performed that it was important, too. The methods which were ranked were as follows; Protecting the body from a harmful state, invigorating the body by the augumentation of heat and avoidance of cold, eating well, handling with whole heart, and keeping clean, resting without working. 3. There were significant differences statistically (paired-t=-8.39, p=.000) of the degree of recognition & performance of traditional postpartal care(Sanhujori) for the postpartal women. The degree of recognition was higher than the degree of performance. So, the recognition of traditional postpartal care (Sanhujori) was higher than the performance of it. 4. There were no statistical differences of the degree of recognition & performance of traditional postpartal care(Sanhujori) among the postpartal women's age, religion, job, educational background, delivery frequency, delivery method or the sex of baby. So, the Characteristics of the respondents were not influenced as far as the degree of recognition & performance of traditional postpartal care(Sanhujori). 5. There were significant differences statistically of the degree of performance of traditional postpartal care(Sanhujori) among the 5 postpartum care centers except 1 postpartum care center(p<.01). So, the recognition of traditional postpartal care(Sanhujori) was higher than the performance of traditional postpartal care(Sanhujori) in the 5 postpartum care centers. But there was performed as good as recognition in only 1 postpartum care center.
