$Chos{\check{o}}n$ Dynasty was governed by the words of king, however, if they were not announced by the form of public document, they were useless. Therefore, the form of public document was the symbol of governing activity, and it was very important to manage the public record in operating the nation affairs. However, the point we should consider is that $Chos{\check{o}}n$ Dynasty, in the case of managing the public record, edited 'the original' instead of preserving them. And so, the preservation of the public record was deeply related to the editing of history. In Late Korea dynasty, the management of the public record got into utter confusion and so many troubles were occurred. In order to resolve these problems, the movements which innovated the public record managements system was gradually extended. This movements were continued in $Chos{\check{o}}n$ Dynasty. Finally, through the several modification procedures, the rules of public record management were legislated by 'Kyong Kuk Dae Jeon'(經國大典). Especially, by laws of 'Kyong Kuk Dae Jeon', not only the daily records of Secretary Department(承政院) but also the important documents which was related to the government branch should be booked in the last decade of the year and the number of the books had to be reported to the king. This rule made certification of the fact that the king was the last confirmer of the public record management. In addition, through the procedure of printing the record of the national affairs, and the diplomatic once in three years, and then preserving that public record in the National Department(議政府), other departments responsible and the archives, the National Department practically took part in the public record management. The management system was also changed in order that the public record was virtually used and consulted before taking the procedure of immortal preservation. All public documents were classified by the definite rule and filed in a same volume. After classifying and filing, certainly, for making convenience of reference and application of public record, records were indicated by the paper card. It may be that, after the step of reference, application and indicating, the public documents were gradually transferred to the next step. In these procedures, Early $Chos{\check{o}}n$ public documents system was confirmed.

'Choyoung', a winter forage triticale cultivar (X Triticosecale Wittmack), was developed at the Department of Rice and Winter Cereal Crop, NICS, RDA in 2015. The cultivar 'Choyoung' has the leaves of medium width, long length and green color and a medium grain of brown color. The heading date of the cultivar 'Choyoung' was April 30 which was 2 days earlier than that of check cultivar 'Shinyoung'. Its tolerance or resistance to cold, wet injury, powdery mildew, and leaf rust was similar to those of the check cultivar. But the resistance to the lodging of cultivar 'Choyoung' was stronger than that of the check. The average forage fresh and dry matter yield of cultivar 'Choyoung' at milk-ripe stages were 40.5 and $15.7MT\;ha^{-1}$, respectively, which were similar to those (40.3 and $16.1MT\;ha^{-1}$) of the check cultivar. The silage quality of 'Choyoung' was higher than that of the check cultivar 'Shinyoung' in crude protein content (5.9%), while was similar to the check cultivar 'Shinyoung' in acid detergent fiber (33.9%), neutral detergent fiber (57.3%), and total digestible nutrients (62.2%). It showed a grain yield of $5.59MT\;ha^{-1}$, which was 38% higher than that of the check cultivar 'Shinyoung' ($4.05MT\;ha^{-1}$). This cultivar is recommended for fall sowing forage crops in areas in which average daily minimum mean temperatures in January are higher than $-10^{\circ}C$.

Objectives: To analyze the relationships of socioeconomic status(SES) to health status and health behaviors in the elderly. Methods: Data were obtained from self-administered questionnaire of 4,587 persons, older than 65 years, living in a community. We measured the sociodemographic characteristics, socioeconomic status, health status (subjective health status, acute disease, admission experience, dental state, chronic disease etc.), activities of daily living (ADL), instrumental activities of daily living (IADL), and mini-mental state examination-Korean (MMSEK). Binary and multinominal logistic regression analyses were employed to analyze factors affecting on the socioeconomic status of the elderly. Results: With regard to the SES and health status, those with a low SES had poorer subjective health states and lower satisfaction about their physical health. Also, acute disease experiences, admission rates and tooth deciduation rates were higher in those of low SES. In the view of physical and cognitive functions, the ADL, IADL and MMSE-K scores were also lower in those of low SES. However, with regard to health behaviors, lower smoking and alcohol drinking rates were found in the low SES group, and a similar trend was shown with regular physical exercise, eating breakfast, and regular physical health check-up. From these findings, we surmise that those with low SES have a poorer health condition and less money to spend on health, therefore, they can not smoke or drink alcohol, exercise and or have a physical health check-up. Conclusion: This study suggests that socioeconomic status plays an important role in health behaviors and status of the elderly. Low socioeconomic status bring about unhealthy behavior and poor health status in the elderly. Therefore, more specific target oriented(esp. low SES persons) health promotion activities for the elderly are very important to improve not only their health status, but their health inequity also.

The purpose of this study was to explore the degree of stress in caregivers caring for CVA patients and the level of daily living performance of CVA patients. The subjects for the study were caregivers of 112 CVA patients who enter a hospital or out-patient-department (OPD) at two Oriental medical hospital in Jeonbuk province. The survey instruments used in this study were Kang's ADL check list for daily living performance of patients and Choi's 4 sore scale for stress of caregivers. The survey was conducted from July 4th to August 30th in 1999. The survey results were analyzed with the Statistical Package for Social Science(SPSS) program and can be summarized as follows: 1. The level of daily living performance for the CVA patients was: 1) complete dependence (M=14.9, 13.1%), 2) complete independence (M=23.6, 20.9%), 3) incomplete independence (M=23.9, 21.0%), 4) incomplete dependence (M=26.6, 25%), 5) dependence and independence (M=23.0, 20.0%). The items for with there was a high level daily living performance were: 1) drinking (M=3.62), 2) eating(M=3.25). 3) position returning (M=3.18) : and the items for which there was a low level of daily living performance were: 1) ascending and descending stairs (M=2.08), 2) walking (M=2.47), 3) dressing and undressing trousers (M=2.55). 2. Degree of caregiver stress was: Mean=2.39 at 40 score. The items for which was a high level caregiver stress were: 1) medical fee (M=3.25), 2) being handicapped or recurrence (M=3.02) : and the items for which there was a low level of caregiver stress were: 1) discontinuity of patient's treatment (M = 1.98). 2) change of home atmosphere caused by patient's disease (M = 1.98), 3) desire of patient's knowing about disease (M= 1.99). 3. There was statistically significant difference in the degree of caregiver stress according to the following caregiver's demographic characteristics: education level (F=3.52, P=0.03). change of caregiver (F=5.41. P=0.02). 4. There was a statistically signifiant difference in the level of daily living performance according to the CVA patients demographic characteristics: patient's paralytic status (F=4.48, P=0.01), duration of disease (t=2.76, P=0.03). 5. There was significant difference in degree of caregiver stress according to the CVA patient's demographic characteristics: CVA status (F=4.75, P=0.01). 6. There was statistically significant difference in the degree of caregiver stress according to the level of daily living performance in CVA patients(r=-0.482, P<0.00).

This investigation on the change of the daily maxima temperature in Seoul, Daegu, Chunchen, Youngchen was triggered by news items such as the earth is getting warmer and a recent news item that said that Korea is getting warmer due to this climatic change. A statistical analysis on the daily maxima for June over this period in Seoul revealed a positive trend of 1.1190 centigrade over the 45 years, a change of 0.0249 degrees annually. Due to the large variation on these maximum temperatures, one can raise the question on the significance of this increase. To check the goodness of fit of the proposed extreme value model, we shown a Q-Q plot of the observed quantiles against the simulated quantiles and a probability plot. And we calculated statistics each month and a tolerance limit. This is tested through simulating a large number of similar datasets from an Extreme Value distribution which described the observed data very well. Only 0.02% of the simulated datasets showed an increase of this degrees or larger, meaning that the probability is very low for such an event to occur.

Purpose: In this study, we tried to check the usefulness of two Linear Accelerators, Clinac IX and 21EX (Varian, Palo Alto, CA), which are equipped in Ajou Medical Center. From 2008 to 2010, we evaluated the error range of Absolute Dose based on the daily output, which was measured by CHECKMATE$^{TM}$ (Sun Nuclear, Melbourne, FL). Materials and Methods: For Daily Q.A, photon beams of two linear accelerators, 21EX and IX (6 MV and 10 MV, respectively) were measured daily by using CHECKMATE$^{TM}$ just before the treatment began, while the absolute dose was measured biweekly by using water phantom. We analyzed the data of measured values from the daily Q.A and the absolute dose from 2008 to 2010 for 21EX, and from 2009 to 2010 for IX. We utilized Excel 2007 (Microsoft, USA) to evaluate Average, Standard deviation and Confidence level of the data. Furthermore, in order to check the measured values of CHECKMATE$^{TM}$ and the significance of absolute dose, each error value was compared and analyzed. Results: During the observation period, the output of two equipment's absolute dose increased in process of time and in both 6 MV and 10 MV, there was a similar increasing trend. In addition, the error rate of the measured value of CHECKMATE$^{TM}$ and the value of absolute dose were under 0.34, which means that there is a similarity relationship between the two measured values. After checking that the measured value of CHECKMATE$^{TM}$ increased, We measured the absolute dose to adjust that. When the error range was close to 2~3%, the number of changing the output was four for 21EX and three for IX. Conclusion: As a result of measuring and analyzing the daily output changes for two years by using CHECKMATE$^{TM}$, we could find that there is a significance between the output which we should obey during Q.A, and the measured value of absolute dose within the error tolerance of 2~3%. Thus, the use of CHECKMATE$^{TM}$ can be positively considered for more efficient and reliable daily output verification of linear accelerator. It can also be a good standard for other medical centers to understand the trends of linear accelerator and to refer to for the correction of each output.

In this study, we proposed a new method that can be measure ECG (Electrocardiography) and PPG (Photoplethysmography) in realtime on the site of the wrist for check the state of health in daily life. For convenience measurement of ECG the lead I method was used on the wrist, and omit the reference junction ECG I was measured in the right hand and the left hand of the potential difference. Then the measured electrocardiogram was amplified by the differential amplifier and the signals were passed HPF, LPF, and BPF filters. For removing the PPG's noise from the Motion artifact and temperature, we apply the reflective photoelectric volume pulse wave measurement method using green LED as a light source. The circuits was designed to be able to check the waveform using higher active amplification method at weak signals. For the validation of our device, the measured signals were compared with E2-KIT on same time. The results shows that the error does not exceed the maximum one, most of the data is confirmed to be issued Peak inspection of the same number.

Objectives: The purpose of the study was to investigate the relationships among snack habits, oral health practice, and oral health status in preschool children. Methods: The subjects were 209 preschool children and their mothers in Jeonbuk from March 24 to May 30, 2014. The study instruments comprised snack habits, oral health practice, and oral health status. Data were analyzed for independent t-test, one way ANOVA and hierarchical multiple regression using SPSS Win 21.0 version. Results: Higher dft index was shown in the older age (p=0.033), lower mother's education (p<0.001), lower mother's daily toothbrushing (p<0.001), check-up after tooth-brushing (p<0.001), tooth-brushing practice before sleeping (p<0.001), tooth-brushing practice after snack (p<0.001), regular dental check-up (p<0.001), fluoride and sealant for prevention caries (p<0.001), limitation of sugar snack intake (p<0.007), periodic replacement toothbrush (p=0.022). The cause of higher dft index included soda (p<0.001), yogurt (p<0.001), snack (p=0.002), bread and cake (p=0.002) and caramel and candy (p<0.001). Fruit (p<0.001), vegetable (p<0.001) and milk (p=0.004) decreased dft index. Factors affecting oral health status were tooth-brushing practice before sleeping, tooth-brushing practice after snack, regular dental check-up, fluoride and sealant for prevention caries, and intake of soda, yogurt, caramel, candy, and fruit. The explanation power of the final model was 67.6%. Conclusions: It is necessary to develop the oral health education program for the preschool children and mothers to enhance the best oral health condition.
