이정희,임창휘,박종원,이상헌,Lee, Junghee,Lim, Chang Hwy,Park, Jong-Won,Lee, Sang Heon 한국정보통신학회 2020 한국정보통신학회논문지 Vol.24 No.12

X-ray of up to 9MeV are used for container inspection. X-ray intensity must be maintained stably regardless of changes in time. If dose is not constant, it may affect the image quality, and as a result, may affect the inspection of abnormal cargo. Therefore, to acquire high-quality images, continuous dose monitoring is required. In this study, the ion-chamber based device was developed for monitoring the dose change in high-energy x-ray. And to estimate the performance of signal-processing device change according to the environmental change, the output changing due to the change of temperature and humidity was observed. In addition, verification of the device was performed by measuring the output change. As a result of the measurement, there was no significant difference in performance due to changes in temperature and humidity, and the change in output according to the change in exposure was linear. Therefore, it was found that the developed device is suitable for the dose monitoring of high-energy x-ray. 일반적으로 컨테이너 내부검사를 위해서는 최대 9MeV의 X-선을 사용한다. 이때 사용되는 X-선은 선형가속기를 통해 생성되며 일정한 세기의 X-선량이 시간의 변화에 관계없이 안정적으로 유지되어야 한다. 만약 발생되는 X-선의 세기가 일정하지 않다면 영상의 해상도와 대비도 등에 영향을 미칠 수 있으며 결과적으로 컨테이너 내부의 이상화물에 대한 검사에 영향을 미칠 수 있다. 그러므로 고화질의 영상을 획득하기 위해서는 발생되는 X-선 선량에 대한 지속적인 모니터링이 요구된다. 이와같은 선량 모니터링을 위하여, 본 연구에서는 고에너지 X-선 선량의 변화 측정을 위한 이온전리함 기반의 선량변화 측정장치를 개발하였고 환경변화에 따른 신호처리부의 성능변화를 확인하기 위하여 온도와 습도 변화에 의한 측정값의 변화를 관찰하였다. 또한, 고에너지 X-선 발생장치에서 발생되는 선량의 변화에 따른 응답특성변화를 측정함으로써 개발한 X-선 선량측정장치의 검증을 수행하였다. 측정결과 온도와 습도의 변화에 따른 성능의 차이가 크게 나타나지 않았으며 입사되는 선량의 변화에 따른 출력의 변화가 선형적이었다. 그러므로 개발한 이온전리함 기반의 선량변화측정장치는 고에너지 X-선의 선량변화의 측정에 적용하기에 적합함을 알 수 있었다.

The standard does much to improve merchantable quality, distribution efficiency and fair dealings by shipping of the standard agricultural products. Mushrooms notified as the standard are five items; Pleurotus ostreatus, Pleurotus eryngii, Flammulina velutipes, Agaricus bisporus and Ganoderma lucidum. But many farmers are suffering from a strict standards. So these standard is required modification to fit farmhouse situations. This study was carried out to investigate mushroom quality of farm shipping and quality change during preservation at various treatment. Flammulina velutipes and Agaricus bisporus preserved at different temperature( 4℃, 10℃, 20℃) to investigate quality changes. Pileus diameters of Flammulina velutipes was 67% of first grade and 33% of second grade at the early stage. After two weeks, pileus diameters was not signigicant changes; 50% of first grade, 50% of second grade at 4℃ and 50% of second grade, 50% of third grade at 10℃. Although there were no significant changes of diameter at 20℃, most of the fruit bodies were decayed. In case of Agaricus bisporus, pileus diameter was 15% of first grade, 81% of second grade and 4% of third grade at the early stage. The more storage period longed, the more the color of the fruit body was browned. But pileus diameters was not signigicant changes. Hardness and chromaticity of these mushroom was declined as time passed. Now we are carrying out more research on some mushroom’s standards for improve consumer confidence.

This study set out to evaluate the appropriateness of the height of a cycle saddle which was usually set based on a cyclist's experience and simple judgment. For this purpose, there was aroused a need to study what a cyclist's leg movements were according to the knee joint angle, that is, to study how a cyclist's leg joint angles and angular velocity would change at each pedaling. Seven male college cyclists were selected, and their pedaling movements were divided into four phases. The images were taped at 60fields/sec, using two video cameras. The KWON 3D 2.1 program was adopted to calculate and synchronize the 3D coordinates values which were calculated with DLT(Direct Liner Transformation), in order to analyze kinematical factors. The results were as follows: 1) There was found no difference between foot joint angles according to changes of knee joint angles in each phase. But it became clear that Phase 1 and 2 where the foot angle got bigger were the area where the foot joint was expanded and that Phase 3 and 4 where the foot angle got smaller were the area where the foot joint was bent. Accordingly, the area which gives a great indirect impact to the changes of foot joint angles is considered to be the first part of Phase 3 at which point the cycle of pedaling starts. 2) In terms of the difference of foot joint angular velocity according to knee joint angles, there was found a relatively stable deceleration in the decelerating area(Phase 3 and 4) while you could detect faster changes in the acceleration area(Phase 1 and 2) than in the decelerating area. 3) The changes in the angle difference of knee joints according to each knee joint angle showed almost similar patterns for every knee joint. But the patterns had the graph model of the opposite shape to that of the angle difference of foot joints. 4) The research went on to see what kind of difference the knee joint angle made as knee joint angular velocity changed. The changes were unlike the foot joint angular velocity and thus showed relatively slow deceleration and acceleration. And the higher the saddle was set, the bigger the difference of the angular velocity was. 5) The difference of hip joint angles according to knee joint angles made a graph pattern which showed no big correlation with the height of a saddle. 6) In considering how hip joint angular velocity would change according to knee joint angles, the higher a saddle was set, the bigger angular velocity was found in Phase 1 and 2, the area of joint expansion and the smaller angular velocity in Phase 3 and 4, the area of joint bending. Comparisons and analysis were made based on the results above mentioned. The conclusion was that the lower a saddle which was one of the three experiment conditions was set, the smoother the pedaling turned and the bigger the angular velocity was resulted. In other words, when you take a long road cycling with your saddle fixed at a little lower height than the average one, you will consume less physical strength and expect better performance.

To detect the numerical changes of the chromosome 13 and 17, containing tumor suppressor genes (retinoblastoma gene and p53) in normal tissue, intraepithelial neoplasm and carcinoma of the prostate, the Fluorescence In Situ Hybridization technique with paraffin embedded tissue was done. Materials observed in this study consisted of 14 cases of lacalized carcinoma(TB1NOMO) and 1 case of locally infiltrating cancer(TC1NOMO)> The chromosomal number changes were counted at normal tissue, intraepithelial neoplasm and neoplastic gland at the same radical prostatectomy specimen. From the 4 patients, studied prospectively, fresh cancer tissue and peripheral whole blood were collected for the primary culture of the cancer cells and lymphocytic culture. There cultured cells were used fro karyotyping. The results were as follows : 1. There were no significant chromosomal number changes between 13 and 17 in each group. 2. The normal non-neoplastice duct, intraepithelial neoplasm and neoplastic gland of experimental group showed no significant difference in chromosomal change. 3. There were significant changes more than 30% in chromosomal numbers between control Y chromosome and experimental chromosome 13 and 17 in each group. 4. The karyotyping on primary cultured prostate cancer cells and lymphocyte showed significant difference in chromosomal number in spite of the same host, representing local chromosomal changes.

Skilled and experienced anestheia is of great importance for patients undergoing orthotopic liver transplantation, because of multiple preexisting medical problems in such patients as well as the intraoperative problems of rapid hemodynamic, metabolic, and coagulation changes. In this study, the intraoperative hemodynamic and laboratory data were analyzed in ten dogs that underwent an orthotopic liver transplantation procedure by veno-venous bypass using Biopump. Liver transplantation can be divided into three distinct periods: stage I, or preanhepatic stage, which begins with the induction of anesthesia and continues until cross clamping of portal vein and IVC; stage II, or anhepatic stage, which begins at the anhepatic time and continues until the donor liver is reperfused by the recipients circulating blood; and stage III, or postanhepatic stage, which begins at the time of reperfusion and continues until the end of surgical procedure. The hemodynamic changes at the time of IVC and portal vein cross clamping were decreases in CVP, PCWP, and pulmonary artery pressure in spite of using Biopump. The significant metabolic alternations during anhepatic stage were decrease in blood glucose levels and increase in blood lactate levels. The more significant hemodynamic changes occurred at the time of reperfusion. Systolic pressure decreased suddenly to 58±6 mmHg and cardiac output decreased to 1.08±0.1l L/min. However heart rate, pulmonary artery pressure, CVP, and PCWP did not change significantly. During stage III, hyperglycemia occurred quite frequently. Significant abnormal coagulation chages could not be found, probably because the dogs were healthy. In conclusion, during anhepatic stage, we have to compensate for alternations of fluid balance. At the time of reperfusion, we should prevent severe hemodynamic changes and treat them immediately if they occur. However, it seems that glucose administration is not necessary to the liver recipient during stage II because there is no significant hemodynamic depression e to hypoglycemia at this time and hyperglycemia occurs later

在日韓國人의 生活文化의 異質化와 適應過程에 關한 保健學的 硏究

After world war Ⅱ Japanese life expectancy has been improved remarkably, and reached the highest level in the world around late 1970's. The life expectancy of Korean has also shown tremendous improvement in recent years with about 20 year's gap from the Japanese. The reason of rapid improvement of life expectancy can be explained by changes in the structure of cause of death due to health system, living standard, social welfare, health behavior of individuals and so on. Korean in Japan is placed under different situations from both Korean in Korea and Japanese in these regards, and expected to show different picture of cause of death pattern. The objective of this study is the comparision of changing patterns of cause of death of three population groups, Korean in Japan, Korean in Korea and Japanese, and to investigate the reasons which effect to the structural difference of mortality cause with special emphasis on health ecological aspects. One of the major limitations of the Korean causes of death statistics is the under-registration which ranges about 10% of the total events, and inaccuracy of the exact cause of death. Some 20% of registered deaths were unable to classify by ICD. However, it is concluded that the Korean data are evaluated as sufficient to stand for over-viewing of trends of cause of death pattern. The evaluation is done by comparing data from registration and field survey over the same population sample. Population data of Korean in Japan differ between two sources of data; census and foreigner's registration. Correction is done by life table method under the assumption that age-specific mortality pattern would accord with that of the Japanese. The crude death rate was lowest among Korean in Japan, 5.7 deaths per 1,000 population in 1965. The crude death rates of Korean in Japan and Japanese are increasing recently influenced by age structure while Korean in Korea still shows decreasing tendency. The adjusted death rate is lowest among Japnaese, followed by Korean in Japan, and Korean in Korea. The leading causes of death of Korean in Korea until 1960's was infectious diseases including pneumonia and tuberculosis. The causes of death structure changed gradually to accidents, neoplasm, hypertensive disease, cerebro-vascular disease in order. The main difference in cause of death between Korean and Japanese is high rate of liver diseases and diabetes for both Korean in Japan and Korea. A special feature of cause of death among Korean in Korea is remakably high rate of hypertensive disease, which is assumed to be caused by physicians tendency in choosing diagnostic categories. The low ischemic heart disease and high vasculo-cerebral disease are the distinctive characteristic of the three population groups compared to western countries. Specific causes of death were selected for detailed sex, age and ethnic group comparisons based on their high death rates. Cancer is the cause of death which showed most drama tical increase in all three population groups. In Korea 20.1% of all death were caused by cancer in 1990 compared with 10.5% in 1981. Cancer of the liver is the leading cause of cancer death among Korean in Japan for both sexes, followed by cancer of the lung and cancer of the stomach, while that of Korean in Korea is cancer of the stomach, followed by cancer of the liver and cancer of the lung for male. Causes of infant mortality were examined among the three population groups since 1980 on yearly bases. For both Japanese and Korean in Japan, leading cause of death ranks as conditions originating in the perinatal period, congenital anomalies, accidents and other violent causes. Trends since 1980 for these two population groups in the leading cause of infant mortality showed no changes. On the contrary, significant changes in leading cause of death structure in Korea were observed : The ranking of leading cause of death in 1981 were congenital asnomali

산림은 많은 양의 탄소를 저장하고 있으며, 산림 탄소 동태는 기후변화에 따라 변화할 것으로 예상된다. 본 연구는 우리나라 산림에서 가장 우점하는 침엽수종과 활엽수종인 소나무림과 참나무림을 대상으로 최근 개발 및 개선된 한국형산림토양탄소모델(Korean ForestSoil Carbon model; KFSC model)을 이용하여 두 가지 기후변화 시나리오(2012년 기온이 2100년까지 유지되는 시나리오(CT), Representative Concentration Pathway(RCP) 8.5 시나리오) 하에서의 산림 탄소 동태를 예측하였다. 5차 국가산림자원조사 자료로부터 소나무림과 굴참나무림 조사구들을 추출한 뒤, 이를 행정구역(9개 도, 7개 특별·광역시) 및 영급(1-5영급, 6영급이상)별로 분류하여 탄소 동태 모의 단위를 설정하였다. 탄소 저장고는 2012년을 기준으로 초기화하였으며, 모의 기간인 2012년부터 2100년까지 모든 교란은 고려하지 않았다. 모의 결과 산림 탄소 저장량은 시간이 경과함에 따라 전반적으로 증가하지만, CT 시나리오에 비하여 RCP 8.5 시나리오 하에서 산림 탄소 저장량이 낮게 나타났다. 소나무림의 탄소 저장량(Tg C)은 2012년에 260.4에서 2100년에는 각각 395.3(CT 시나리오) 및 384.1(RCP 8.5 시나리오)로 증가하였다. 굴 참나무림의 탄소 저장량(Tg C)은 2012년에 124.4에서 2100년에는 219.5(CT 시나리오) 및 204.7(RCP 8.5 시나리오)로 각각 증가하였다. 5차 국가산림자원조사 자료와 비교한 결과, 고사유기물 탄소 저장량의 초기값은 타당한 것으로 나타났다. 모의 기간 동안 소나무림과 굴참나무림의 연간 탄소 흡수율(g C m-2 yr-1)은 CT 시나리오 하에서 각각 71.1과 193.5, RCP8.5 시나리오 하에서 각각 65.8과 164.2로 추정된다. 따라서 우리나라 소나무림과 굴참나무림의 탄소 흡수잠재력은 지구 온난화에 의하여 감소할 것으로 예상된다. 비록 모델의 구조와 파라미터로부터 불확실성이 존재하지만 본 연구는 미래 산림 탄소 동태 파악에 기여할 것으로 기대된다. Forests contain a huge amount of carbon (C) and climate change could affect forest C dynamics. This study was conducted to predict the C dynamics of Pinus densiflora and Quercus variabilis forests, which are the most dominant needleleaf and broadleaf forests in Korea, using the Korean Forest Soil Carbon (KFSC) model under the two climate change scenarios (2012-2100; Constant Temperature (CT) scenario and Representative Concentration Pathway (RCP) 8.5 scenario). To construct simulation unit, the forest land areas for those two species in the 5th National Forest Inventory (NFI) data were sorted by administrative district and stand age class. The C pools were initialized at 2012, and any disturbance was not considered during the simulation period. Although the forest C stocks of two species generally increased over time, the forest C stocks under the RCP 8.5 scenario were less than those stocks under the CT scenario. The C stocks of P. densiflora forests increased from 260.4 Tg C in 2012 to 395.3 (CT scenario) or 384.1 Tg C (RCP 8.5 scenario) in 2100. For Q. variabilis forests, the C stocks increased from 124.4 Tg C in 2012 to 219.5 (CT scenario) or 204.7 (RCP 8.5 scenario) Tg C in 2100. Compared to 5th NFI data, the initial value of C stocks in dead organic matter C pools seemed valid. Accordingly, the annual C sequestration rates of the two species over the simulation period under the RCP 8.5 scenario (65.8 and 164.2 g C m-2 yr-1 for P. densiflora and Q. variabilis) were lower than those values under the CT scenario (71.1 and 193.5 g C m-2 yr-1 for P. densiflora and Q. variabilis). We concluded that the C sequestration potential of P. densiflora and Q. variabilis forests could be decreased by climate change. Although there were uncertainties from parameters and model structure, this study could contribute to elucidating the C dynamics of South Korean forests in future.

태극권의 원리에 관한 연구

김창룡,박종구 龍仁大學校 武道硏究所 2004 武道硏究所誌 Vol.15 No.1

This study set out to investigate if the many different schools were different as much as they looked different on the outside or if they still shared the same contents in the theories of Taijiquan despite the different appearances by comparing the histories, theories, and Quanjia(拳架) of the schools with the focus on Chenjia-taijiquan(陳家太極拳). It also aimed to confirm the results of the consideration of the histories and theories by comparing each school's Taijiquan(太極拳) and Quanjia(拳架). The findings were as follows: 1) The sameness and the difference in the aspect of history of Taijiquan(太極拳) Taijiquan was reviewed from the origin to the differentiation and development. As a result, today's Taijiquan was the product of the original form practiced in Chenjiagou(陳家溝) being completed as the modern Taijiquan and gradually distributed and spread outside. The review of the history of Taijiquan revealed that it accomplished more fresh developments in many aspects after it was being distributed outside than it was limited within the region of Chenjiagou(陳家溝) and the Chen family. First, there were developments and systematization in terms of theories. It should be acknowledged that all the theoretical establishments were already prepared as the modern Taijiquan(太極拳) began to form in Chenjiagou(陳家溝). What is argued here is that it was after Taijiquan moved out of Chenjiagou(陳家溝) that the theoretical systems turned more refined and systematic. In other words, there was already a complete set of the secrets in which all the experiences and know-how from Chen wang-ting(陳王延) and Chen chang-xing (陳長興2) were accumulated for generations even in the era of Chenjiagou(陳家溝). But the secrets and tricks of the original Chenjiagou(陳家溝) enjoyed a lot of boons only after Wu yu-xiang(武禹襄) and Li yi-yu(이역여) integrated the theories of Greate Absolute and yin and yang(太極陰陽) into the Taijiquan(陳家溝) and thus the name of Taijiquan(陳家溝) was appointed as the official name. The biggest driving force that made all those happen was the wide spread of Taijiquan(太極拳3), which was backed up by the refined concerning writings by the addition of literary men and noblemen to the group of Taijiquan. Second, there were more than the theories that were under mutual influences after Taijiquan being spread outside. In the process of Taijiquan 's differentiation and development, Dajia(大架) and Xiaojia(小架) were established by Chenjia-taijiquan(陳家太極拳), which in turn exchanged mutual impacts with other schools that were being formed and drew and absorbed the influences from other schools. As a result, the appearances of Taijiquan became different somewhat along with the interpretations of the terms, but the basic mental techniques of Taijiquan seemed to be shared among the different schools. Thus there would be no opposition to saying that Taijiquan(陳家溝) could be used to refer to all the different schools with seemingly different appearances. The sameness and the difference in the aspect of theories of Taijiquan(陳家溝) The Taijiquan(太極拳) theories of each school were compared. As a result, having originated from the traditions represented by the Quanjing(拳經) of Qi ji-guang(威繼光), the concerned theories earned a new creative slogan called Taijiquan thanks to Chen wang-ting(陳王延). With the Chenjiagou(陳家溝) as the tradition, the outside creations followed their own growing path being represented by Wang zong-yue(王宗岳) and Wu yu-xiang(武禹襄). Then the concerned theories and creations combined together as the situations of the times changed, which results corresponded to the findings according to the chronological order. There was a strong sense of the process of thesis-antithesis-synthesis, where new creations were made based on the traditions, then the traditions were separated from the creations, and then there was another combination together. In today's world, there are many different schools of Taijiquan, which are operated in the same principles and rules based on the common roots. That should be the reason why Taijiquan can be nothing but Taijiquan no matter differences there are among the schools. The flow in the history has resulted in the different styles of five major schools of today's Taijiquan, which still have common features in the body and limb principles and rules. Thus it was confirmed that Taijiquan has not evolved into different types of Taijiquan based on the appearances but taken different outside forms according to the goals of practicing and spreading it or the degree of cultivation and tastes of Taijiquan people. The sameness and the difference in the aspect of each school's Taijiquan(太極拳) based on the Quanjia(拳架 comparison The Quanjia(拳架)(Taolu 套路) of each school was compared in the composition and common Zhaoshi(超式) in order to compare their Taijiquan. As a result, even though the names of Zhaoshi(超式) were changed and went through partial omission, replacement, alteration, addition, and simplification, the Taijiquan of each school turned out to share the same family line based on the Laojia(老架) of Chenjia-taijiquan(眞家太極拳). Then going into details of Zhaoshi(招式) led to the selection and comparison of several Zhaoshi(招式). After the comparison methods and scopes were decided, it was investigated what caused the outside changes to Taijiquan(太極拳). The results confirmed that even though the Zhaoshi(太極拳) of each school that originated from Chenjia-taijiquan(陳家太極拳) appeared very much different from the outside, they shared the same implications on the inside. It would be reasonable to argue that the outside appearances that seemed very much different in the overall structure or individual Zhaoshi(招式) were the products of each school's responding to the needs for spreading their Taijiquan for survival. That is, they just tried to pursue "Eungmuljayean(應物自然 : means unify with every object in nature)" of Taijiquan(太極拳) by taking proper measures responding to the changing situations of the times. In short, there were changes that led to the partial differences of some schools in appearance due to the creative growth and differentiation of Taijiquan(太極拳) itself in terms of theories and practice or some alterations that led to the simpler Taijiquan(太極拳) for the purpose of distribution. Despite the outside differences, however, the changes of each school remained royal to the essential meaning of Taijiquan(太極拳). Thus it's a reasonable argument that each school including not only Laojia(老架), Paochui(포추), Xinjia(新架), and Xiaojia(小架) of Chenjia-taijiquan(陳家太極拳) but also Yangia(楊家), Wujia(吳家), Wujia(武家), and Sunjia(孫架) all belongs to the same Taijiquan(太極拳) in contents.

전기자극과 운동치료가 뇌졸중환자의 보행에 미치는 영향

송창호,이종삼 한국스포츠리서치 2004 한국 스포츠 리서치 Vol.15 No.5

This study, adopting the pretest-post test experimental study, is designed to find out how the functional electrical stimulation makes effect on the walking of a patient with spasticity of the ankle plantarflexor muscle caused by hemiplegic after stroke. The 46 subjects for this study were randomly sampled out of the patients who were hospitalized from September 1, 2003 to November 30, 2003 in A hospital in Kyungki-do. The patients were with spasticity of the ankle plantarflexor muscle caused by hemiplegic after stroke and able to walk without supporting implements. The purpose of the study is firstly to analyze the change of ROM, TUG, 10mWT of a patient with spasticity of the ankle plantarflexor muscle when the functional electrical stimulation is applied and secondly to find out how the sex, age, height, weight, part of the diagnosis, duration of pain, experience of relapse and getting hurt from a fall of a patient make effect on the change. The ROM test was performed to check the range of motion of the ankle with a double armed universal goniometer. The test was done 3 times to take an average. TUG and 10mWT were for walking test. The statistical test was conducted using the SPSS 10.0/PC program by means of the following methods: x^2-test and t-test for testing homogeneity between the groups; paired t-test, independent sample t-test, F-test, and two-way ANOVA for analyzing the changes before and after the treatment, differences between the groups, and the affecting factors on the changes and, Pearson's correlation coefficient for testing the correlation between the changes in the dependent factors, The levels of statistical significance of all the data were maintained at p<.05. According to the test, ROM has more decreased in experimental group than in control group when the functional electrical stimulation was applied only to the experimental group. However, the significant statistic difference was not shown (p=.059). All of TUG 10mWT showed remarkable differences in the experimental group compared to the control group, showing the significant statistic difference (p=.000). On the one hand, the change of ROM TUG and 10mWT related with the HE, age, height, weight, part of the diagnosis, and experience relapse was a meaningless minimum value, The change of ROM related to the duration of pain and the experience of falling down was also meaningless, However, TUG, 10mWT showed significant statistic difference (p<.05), According to the test above, the application of functional electrical stimulation to a patient with spasticity of the ankle dorsiflexor muscle caused by hemiplegic after stroke makes significant effect on the walking of a patient, but the result has nothing with the sex, age, height, weight, part of the diagnosis, duration of pain, experience of relapse and getting hurt from a fall of a patient, The range of motion of the ankle doesn't show significant correlation with other dependant factors, However, it is regarded to give contribution to the balance and walking improvement of a patient. Therefore, this study expects to be a valuable clinical material for a patient with spasticity.
