The purpose of this study was to analyze the kinetics variables of GRF by dtance type during forehand stroke. Eight high school tennis players, who have never been injured for last six months, in Busan were chosen for the study. They performed horizontal swing and vertical swing that it was done each five consecutive trial in the condition of square, semi-open and open stance. It was filmed by 6 video camera and used with 3-dimensional motion analyzer system and GRF system. The following kinetic variables were analyzed in relation to left leg and right leg GRF. The conclusion were as follow: 1. In square and semi-open stances, the horizontal ground reaction force was decreased at impact in left leg regardless of swing type, whereas open stance was increased at impact to the tiptoe in both legs. 2. In square and semi-open stances, the vertical ground reaction force was increased at impact in left leg regardless of swing types, whereas open stance was decreased at impact to vertical direction in both legs.

In this study, we studied the effect of onion on hyperlipidemia in terms of factors, such as body weight, liver weight, kidney weight, heart weight, blood glucose, total cholesterol, triglycerides, HDL-cholesterol, and LDL-cholesterol. The hyperlipidemia supplement was significantly effective on the liver weight, kidney weight, blood glucose, total cholesterol, triglycerides, and LDL-cholesterol with the fixed effect model. However, the liver weight, blood glucose, total cholesterol, and triglycerides were significantly decreased with the random effect model on the heterogeneous factors selected by Galbraith plot. The existence of publication bias was checked by using a funnel plot.

The present study was carried out to summarize the effect of propolis in the diabetic rats by meta-analysis related studies. The association measure to test effect of propolis was Hedges's standardized mean difference between group of rats induced streptozotocin(STZ) or alloxan and group of rats induced STZ or alloxan treated with propolis about the considered 4 effect factors. In this particular fixed-effect model, blood glucose, Cholesterol, Triglyceride were significantly reduce. The case of heterogenous variable such as body weight, blood glucose, cholesterol, triglyceride, random-effect model was applied. In this model, blood glucose, triglyceride were decreased significantly in propolis treated group. According to the meta-regression analysis, period of injection was significant for body weight and blood glucose, cholesterol.

This paper presents controller design of a two wheeled mobile inverted pendulum robot for one man transportation vehicle. Since the overall mass is varying with different drivers, suitable controller gains are obtained through experimental studies. Variation of the center of gravity due to different masses also affects stable balancing control. Thus, the desired balancing angle si required to be modified with respect to different masses. To measure masses for different drivers, a weight scale is used and those data are used for balancing control through communication. The gain scheduling method of using data obtained from experimental studies allows the robot to have stable balancing performances.

Lifelog is a digital record of an individual collected from various digital sensors, and includes activity amount, sleep information, weight change, body mass, muscle mass, fat mass, etc. Recently, as wearable devices have become common, a lot of high-quality lifelog data is being produced. Lifelog data shows the state of an individual's body, and can be used not only for individual health care, but also for causes and treatment of diseases. However, at present, AI/ML-based correlation analysis and personalization are not reflected. It is only at the level of presenting simple records or fragmentary statistics. Therefore, in this paper, the correlation/relationship between lifelog data and disease, and AI/ML technology inside lifelog data are examined, and furthermore, a lifelog data analysis process based on AI/ML is proposed. The analysis process is demonstrated with the data collected in the actual Galaxy Watch. Finally, we propose a future convergence service roadmap including lifelog data, diet, health information, and disease information.

건강관련 요인에 따른 우리나라 성인 여성의 영양섭취 특성을 파악하기 위해 2001 국민건강ㆍ영양조사-영양조사부문의 결과를 심층 분석하였다. 2001 국민건강ㆍ영양조사는 2001년 11월 1일부터 12월 31일까지 전국 200개 지역에서 약 4,000가구, 14,000명을 대상으로 실시되었으며, 본 연구에서는 응답자 중 20세 이상 성인여성 3,780명의 데이터만을 활용하였다. 이들의 연령, 소득수준, 건강 인식도, 비만도 및 체중인식 등에 따른 영양소 섭취수준을 비교하였으며, 평균값의 차이에 대한 유의성 검증에는 1-way ANOVA와 Duncan's multiple range test를 적용하였다. 분석의 대상이 된 성인 여성 응답자의 구성은 20∼29세가 696명, 30∼49세가 1,765명, 50∼64세가 757명, 65세 이상이 562명이었다. 20세 이상 모든 성인 여성의 영양소별 영양권장량에 대한 평균 섭취수준을 보면 칼슘의 경우에 67%로 가장 낮았으며 다른 영양소의 경우에는 권장량에 근접하는 것으로 나타났다. 그러나 연령층별로 비교하면 철의 섭취수준은 20대 여성에서 가장 낮은 반면, 나머지 영양소의 섭취 수준은 65세 이상 연령층에서 가장 낮았다. 2001년 가구원 수 별 최저 생계비를 기준(100%)으로 하여 가구소득을 100% 미만, 100∼199%, 200∼299%, 300% 이상 4 구간으로 분류한 소득수준에 따른 영양소 섭취수준을 비교한 결과, 전체적으로는 소득수준이 높아질수록 평균 영양소 섭취수준이 높아지고, 가구 소득이 저생계비 미만인 그룹에서 거의 모든 영양소의 섭취수준이 가장 낮게 나타났으나, 55세 이상 연령층에서는 소득수준이 영양소 섭취 수준에 영향을 미치지 않았다. BMI를 기준으로 저체중군, 정상체중군, 과체중군으로 분류한 비만도 그룹별 영양소 섭취수준을 비교한 결과, 전체적인 영양소의 섭취수준이 정상체중군에서 높고 저체중군에서 가장 낮았으며, 특히 65세 이상 연령층의 저체중군의 섭취수준은 매우 낮아서 칼슘과 비타민 A의 경우 권장량의 40% 대에 불과했다. 자신의 체형에 대한 인식에 근거해 영양소 섭취수준을 비교해 보면, 20대에서는 자신이 말랐다고 인식하는 그룹에서 섭취수준이 다소 낮게 나타났으나 30∼49세에서는 말랐다고 인식하는 그룹의 영양소 섭취수준이 오히려 높은 것으로 나타나 연령에 따라 다른 경향을 보였다. 건강 인식도에 따른 분석 결과, 스스로가 건강하지 못하다고 생각하는 그룹에 비해 건강하다고 인식하는 그룹에서 철을 제외한 모든 영양소의 섭취수준이 유의적으로 높게 나타났다. 이상으로부터 우리나라 여성 중 65세 이상 노인과 최저생계비 미만의 저소득 가구 여성의 영양소 섭취 수준이 심각하게 낮으며, 소득 수준 차상위 계층(100∼199%) 여성의 섭취 상태도 관심을 기울여야 할 수준임을 알 수 있었다. 동시에 자신의 건강이나 체형에 대한 인식이 부정적일수록 섭취수준이 불량하여 한국 여성의 건강과 올바른 영양관리를 위해서는 여성 스스로의 긍정적인 사고 또한 중요한 영향 요인인 것으로 나타났다.

It is currently being used or being developed mobile fitness application systems associated with the most obese. These systems give or notify the user to reduce the weight, check your momentum to inform your calories burned. However, the accuracy is low because it provides and manages the common data without considering the individual characteristics or the environment of the user. In this paper analyzes the disadvantage of mobile fitness system. To solve this problem it presents the data sharing mechanism to alert you to the exercise equipment with the other users belonging to the BMI group, such as yourself. And it proposes the design of a mobile fitness system which is based on the data sharing mechanism.

The health of the companion animal is one of the most important factors for the owners. However, many owners are not aware of their companion's obesity condition. Data shows that 40% of dogs are suffering from obesity. This application is designed for and compatible with high-volume-user devices such as Android-based devices. The size of the application is reduced keeping standard data such as weight and vaccination date of species on servers and analyzing and fetching these data when user inquires about. Finally, the application has an added component of community space in order to share the knowledge among the number of users.

국내에 종오리(PS)를 수출하고 있는 프랑스 오리 육종전문회사 "그리므드(Gremaud Freres)"에서 현재 오리 품종이 개량 및 사양관리를 담당하고 있는 로렌트 버나드(Laurent Bernard)박사가 지난 9월 1일 한국을 방문하였다. 이번 내한 목적은 현재 그리므드사의 종오리를 수입하고 있는 국내 부화장 및 계열 업체를 방문하여 현재 사육 중인 STAR-53 종에 대한 의문점을 풀어주고 개선사항 등 전반적인 사양관리에 대한 노하우를 전수하기 위한 것이다. 로렌트 박사는 지난 2월 방문때와 마찬가지로 사육시 주령별 체중이나 사료급이나 등을 철저히 기록하고 분석하여 정확한 데이터를 보유하고 있어야만이 그리므드사에서도 보다 한국실정에 맞는 오리의 육종이 가능할 수 있다고 재차 강조하였으며 앞으로 STAR 종의 육성율 및 산란율을 증대시키기 위해 최선을 다 할 것을 다짐하였다.

Thc CCD earth image experiment(CEIE) is one of the main payload of the KITSAT-1. Since it was launched on Age. 11, 1992, the CEIE has taken more than 500 images on the earth surface world-wide so far. An image from the space is very different from a feature on the real Earth surface due to various radiometric and geometric distortions. Preprocessing to remove those distortions has to take place before the image data are processed and analyzed further for various applications. This paper summarizes the result of the operation of the CEIE and describes the procedure to perform preprocessing including radiometric and geometric correction.
