The purpose of this study was to identify the characteristics and physiological variables of chest pain induced by exercise test in angina suspected patients. The subjects of this study consisted of 28 inpatients and outpatients aged between 40 and 75 who underwent treadmill test at exercise testing laboratory of S-University from January 2000 to June 2000. Subjects were interviewed with questionnaire regarding sociodemography, the past health history and history related to chest pain before the exercise test. Subjects were interviewed with questionnaire concerning quality, intensity, duration of chest pain induced by walking on the treadmill(Marquette, U.S.A. 1992) according to Bruce protocol following exercise test. Systolic and diastolic blood pressure were measured before, during and after the test, heart rate was determined by ECG. The results of this study were as follows ; 1) Quality of chest pain induced by exercise test were feeling stiffness 19(67.9%), heavy 10(36.0%), exploded 9(32.1%), crushing, suffocating, tight 8(28.6%), stuffy, prickly 7(25.0%), burning 6(21.4%), clasp 5(17.9%), cleaved, tensed, piercing 3(10.7%), perfectly fitting, sore 2(7.1%), tearing, tingling, ticklish, heartburn 1(3.6%). 2) Mean score of VAS(intensity of pain) following exercise test was $5.79{\pm}2.27$ and mean duration of chest pain after the test was $7.83{\pm}5.31$ minutes. 3) Sites of chest-pain induced by exercise test were middle site 11(39.3%), left-chest 10(35.6%), right-chest 6(21.5%). Radiation site of chest-pain was neck(18.0%), right flank site 1(3.6%), left shoulder & arm 2(7.1%) and back 1(3.6%). 4) Symptoms other than chest-pain induced by exercise test were dyspnea 21(75.6%), perspiration 14(50.4%), fatigue 12(43.2%), leg-pain 11(39.6%), dizziness 7(25.2%) anxiety toward chest-pain 3(10.8%), thirst 2(7.1%), and palpation, headache and tingling sensation of hand and leg 1(3.6%). 5) Mean MET(intensity of exercise) during the exercise test was $7.64{\pm}2.57$ and mean RPE(rating of perceived exertion) was $15.89{\pm}2.36$. Mean duration of exercise was $6.79{\pm}2.88$. 6) correlation coefficients between RPE and VAS was 0.500(p=0.003), those between MET and VAS was 0.287(p=0.069) and those between either depression or elevation of ST segment and VAS was 0.236(p=0.114). 7) There was a significant difference in mean systolic pressure between before and after the test as $146.29{\pm}28.18mmHg$ and $177.96{\pm}28.82mmHg$(t=-5.640, p=0.000), a significant difference in mean diastolic blood pressure between before and after the test as $84.85{\pm}15.07mmHg$ and $88.89{\pm}13.72mmHg$(t=-2.082, p=0.047), and there was a significant difference in mean heart-rate between before and after the test as $81.89{\pm}12.22/min$ and $160.68{\pm}21.77/min$(t=-21.255, p=0.000).

구글에서 공개한 Tensorflow를 이용한 여러 학문 분야의 연구가 활발하다. 농업 시설환경을 대상으로 한 빅데이터의 축적이 증가함과 아울러 실효적인 정보 획득을 위한 각종 데이터 분석 및 마이닝 기법에 대한 연구 또한 활발한 상황이다. 한편, 타 분야의 성공적인 심층학습기법 응용사례에 비하여 농업 분야에서의 응용은 초기 성장 단계라 할 수 있다. 이는 농업 현장에서 취득한 정보의 난해성 및 완성도 높은 생육/환경 모델링 정보의 부재로 실효적인 전과정 처리 기술 도출에 소요되는 시간, 비용, 연구 환경이 상대적으로 부족하기 때문일 것이다. 특히, 센서 기반 데이터 취득 기술 증가에 따라 비약적으로 방대해진 수집 데이터를 시간 복잡도가 높은 심층 학습 모델링 연산에 기계적으로 단순 적용할 경우 시간 효율적인 측면에서 성공적인 결과 도출에 애로가 있을 것이다. 매우 높은 시간 복잡도를 해결하기 위하여 제시된 하드웨어 가속 기능의 경우 일부 개발환경에 국한이 되어 있다. 일례로, 구글의 Tensorflow는 오픈소스 기반 병렬 클러스터링 기술인 MPICH를 지원하는 알고리즘을 공개하지 않고 있다. 따라서, 본 연구에서는 심층학습 기법 연구에 있어서, 예상 가능한 다양한 자원을 활용하여 최대한 연산의 결과를 빨리 도출할 수 있는 하드웨어적인 접근 방법을 모색하였다. 호스트에서 수행하는 일방적인 학습 알고리즘과 달리 이기종간 심층 학습이 가능하기 위해선 우선, NFS(Network File System)를 이용하여 데이터 계층이 상호 연결이 되어야 한다. 이를 위해서 고속 네트워크를 기반으로 한 NFS의 이용이 필수적이다. 둘째로 제한된 자원의 한계를 극복하기 위한 메모 공유 라이브러리가 필요하다. 셋째로 이기종간 프로세서에 최적화된 병렬 처리용 컴파일러를 이용해야 한다. 가장 중요한 부분은 이기종간의 처리 능력에 따른 작업을 고르게 분배할 수 있는 작업 스케쥴링이 수행되어야 하며, 이는 처리하고자 하는 데이터의 형태에 따라 매우 가변적이므로 해당 데이터 도메인에 대한 엄밀한 사전 벤치마킹이 수행되어야 한다. 이러한 요구조건을 대부분 충족하는 Open-CL ver1.2(https://www.khronos.org/opencl/)를 이용하였다. 최신의 Open-CL 버전은 2.2이나 본 연구를 위하여 준비한 4가지 이기종 시스템에서 모두 공통적으로 지원하는 버전은 1.2이다. 실험적으로 선정된 4가지 이기종 시스템은 1) Windows 10 Pro, 2) Linux-Ubuntu 16.04.4 LTS-x86_64, 3) MAC OS X 10.11 4) Linux-Ubuntu 16.04.4 LTS-ARM Cortext-A15 이다. 비교 분석을 위하여 NVIDIA 사에서 제공하는 Pascal Titan X 2식을 SLI로 구성한 시스템을 준비하였다. 개별 시스템에서 별도로 컴파일 된 바이너리의 이름을 통일하고, 개별 시스템의 코어수를 동일하게 균등 배분하여 100 Hz의 데이터로 입력이 되는 온도 정보와 조도 정보를 입력으로 하고 이를 습도정보에 Linear Gradient Descent Optimizer를 이용하여 Epoch 10,000회의 학습을 수행하였다. 4종의 이기종에서 총 32개의 코어를 이용한 학습에서 17초 내외로 연산 수행을 마쳤으나, 비교 시스템에서는 11초 내외로 연산을 마치는 결과가 나왔다. 기보유 하드웨어의 적절한 활용이 가능한 심층학습 기법에 대한 연구를 지속할 것이다

The main purposes of the nutrition and clinical surveys were to provide baseline information on the nutritional status of pre-school children in rural health demonstration project areas of the Korea Health Development Institute (KHDI) for nutrition guidance services for the MCH target group. The survey covered a total of 222 pre-school children and 135 mothers in Okgu Gun, Cholla Pukto Province from August 10 to August 17, 1979. The survey results are summarized as follows: 1) Family Environment Seventy percent of the households had more than three children, and the mean family sire was 6. Sixty-nine percent of the mothers and 47% of the fathers of the surveyed households were educated at or below the primary school level. The majority, 70% of the mothers, were aged between 20 years and 35 years. 2) Anthropometric Measurements and Hemoglobin Value 4.5% of the children were lower than 80% weight for age of the Korean standard, and 5.4% were lower than 85% arm circumference for age of the Jelliffe's standard resectively, and those were suffering from protein-energy malnutrition. Angular stomatitis were observed on 66.2% of the subjects. Mean hemoglobin value was 11.1g/100m1, and 44.2% of the subjects were categorized as anaemia. 3) Food and Nutrient Intake of animal foods was very low, ranging from 2.9 to 17%. Consumption of eggs was less than 2% of total food intake, and intake of legumes was also very scanty, between 0.8 to 3.7%. These data present evidence of very poor protein intake, quality as well as quantity. Energy intake of children was 60.0 to 64.4% of the recommended allowance, and mean protein intake only met 47.4% of the recommendation. Low intake of vitamins except thiamin were also found. 4) Mother's Nutrition Knowledge Eighty-five percent of the mothers were entirely ignorant regarding the 'five basic food group' which is most important fact on food and nutrition guidance. Mean knowledge score from 14 basic questions about food and nutrition was as low as 5.1. There was a significant positive correlation between mother's educational level and nutrition knowledge score. 5) Family Planning Variable There were significant correlation among maternal, family planning variables, and some of the nutritional and physical measurements. The study revealed that the mother's educational level and nutrition knowledge score are more crucial factors than the family planning variables on effecting food intakes on children. Recommendation : According to the results of the surveys, there were high incident rates of nutritional anaemia and angular stomatitis among pre-school children, and most of rural women had very limited knowledge about food and nutrition. As a main part of the health education activities, the community health workers should provide nutrition education to the village mothers to improve the nutrional status of young children in rural areas. Nutrional promotion at the primary health care level should be mainly based on appropriate nutrition education.

There are many types of walking exercise. We have choice the way according to the walking exercise purpose. Nordic walking(NW) is one of walking types with nordic poles. Also, power walking(PW) has motion of large swing the arm in walking, and dumbbell walking(DW) way is walking with 3-pound dumbbell. This study compared the physiological response(heart rate, energy expenditure) of general walking(GW) to another types(nordic, power, and 3-pound hand weights walking way). Seven apparently male health volunteers between the ages 19 and 24 years participated. Each complete a treadmill test. The tests were assigned randomly, as submaximal walking trials on separate days. Each walking trial was conducted on a level treadmill, for 40 minutes(3-5mile/hour 5min warm-up, 6mile/hour speed for 15min walking and 7mile/hour speed for 15min Jogging exercise, and 5-3mile/hour cool down 5min), at an same pace. Heart rate in beats per minute(bpm), and energy expenditure in kcal per minute(kcal/min) were recorded each minute. Results between trials were compared using repeated measures analysis of variance and Tukey's post hoc tests. In slow walking, it was found that walking with 3-pound hand weight way resulted in and average of ($127.8{\pm}8.27bpm$) the highest score HR, Caloric expenditure($85.4{\pm}14.51kcal/min$), responses compared to regular walking way($117.4{\pm}7.27bpm$ and $70.4{\pm}10.99kcal/min$). Nordic walking way($121.4{\pm}11.74bpm$, and $77.0{\pm}16.83kcal/min$) is second, power walking way($118.5{\pm}9.98bpm$, and $68.7{\pm}20.62kcal/min$) is next. In fast walking, it was found that walking way with 3-pound hand weight resulted in and average of ($160.1{\pm}8.72bpm$) the highest score HR, caloric expenditure($126.1{\pm}13.86kcal/min$), responses compared to regular walking way($148.4{\pm}11.94bpm$, and $109.0{\pm}4.70kcal/min$). Nordic walking way($156.7{\pm}10.82bpm$, and $113.5{\pm}14.51kcal/min$) is second, power walking way($149.7{\pm}12.56bpm$, and $109.2{\pm}17.64kcal/min$) is next. Thus, it is the unavoidable conclusion that, comparing with general walking, 3-pound hand weight walking, nordic walking, and power walking methods have the advantage of high exercise intensity and energy expenditure to meet the purpose of performers without the problem. Furthermore, 3-pound hand weight walking ways were proved to be a useful aerobic exercise method as whole body that achieves high-energy efficiency. To this extent, 3-pound hand weight walking ways can be recommended as a continuous and regulative aerobic exercise for some people.

The aim of this study was to evaluate the effects of Jowiseungcheongtang compared with St. John's wort in the chronic mild stress(CMS) animal model of depression. Wistar rats were used for this study. The subjects were divided into 4 groups (Naive group: without CMS procedure, CMS-vehicle: water was administered during CMS procedure, CMS-Jowiseungcheongtang: Jowiseungcheongtang was administered after 5 weeks of CMS procedure, CMS-St. John's wort: St. John's wort was administered after 5 weeks of CMS procedure) During 9 weeks of CMS procedure, The change of the consumption of sucrose and the changes of weights were measured. After CMS procedure, Morris water maze test, open field test, elevated plus maze test and Western blotting were measured. The results were as follows. 1. The consumption of sucrose solution was significantly reversed in Jowiseungcheongtang group and relatively reversed in St. John's Wort group at 7 week. 2. In open field test, Neither Jowiseungcheongtang nor St. John's wort group showed statistically significant change of exploratory activity. In EPM test, St. John's Wort group showed significant decrease of total arm entry in comparison with Naive group. And Jowiseungcheongtang group was showed no significant change. 3. In Morris water maze test, St. John's Wort group showed significant increase in escape latency of the last Morris water maze trial. And in water maze probe test, there was no significant change. 4. St. John's Wort group showed relative increase in LP1 division of 5HT1A receptor compared with Naive group. Both St. John's Wort and Jowiseungcheongtang group showed relative increase in P2 division of GluRl compared with Naive group. These results suggest that Jowiseungcheongtang is as effective as St. John's Wort in the treatment of depression.

To enhance the consumption of horse meat, its nutritional composition was analyzed and compared to that of white meat (i.e., chicken and duck), which consumers consider healthy. Horse meat samples used in the experiment were classified by breed and grade as follows: Jeju horse (grade $1^+$ and 1), Jeju crossbred horse (grade 1 and 2), Thoroughbred (no grade), and cuts (loin, chuck roll, and arm picnic). In an analysis of general components and cholesterol, the horse meat was confirmed as a low-fat, high-protein, and low-cholesterol food material. In an amino acid analysis, horse meat contained a higher proportion of essential amino acids than white meat. The fatty acid compositions were also analyzed. The content of linolenic acid, an essential fatty acid, was significantly higher in all horse meat groups than in Ross chicken and Pekin duck meat. The content of palmitoleic acid showed similar results. In a mineral analysis, the levels of Fe and Zn in horse meat were higher than those of white meat. The mineral content was as follows except for the leg of shite meat: K > P > Na > Mg > Ca > Zn > Fe.
