This study was conducted to estimate the greenhouse gas emissions on local government levels from 1990 to 2010 using 2006 IPCC guideline methodology. To calculate greenhouse gas emissions based on the 16 local governments, emission factor and scaling factor were used with default value and activity data came from the food, agricultural, forestry and fisheries statistical yearbook of MIFAFF (Ministry for Food, Agriculture, Forestry, and Fisheries). The total emissions in crop sector gradually decreased from 1990 to 2010 due to a decline in agricultural land and nitrogen fertilizer usage. The annual average emission of greenhouse gas was the highest in Jeonnam (JN) with 1,698 Gg $CO_2$-eq and following Chungnam (CN), Gyungbuk (GB), Jeonbuk (JB) and Gyunggi (GG). The sum of top-six locals emission had occupied 83.4% of the total emission in cropland sector. The annual average emissions in 1990 by applying 2006 IPCC guideline were approximately 43% less than the national greenhouse gas inventory by 1996 IPCC guideline. Jeonnam (JN) province occupied also the highest results of greenhouse gas emission estimated by gas types (methane, nitrous oxide and carbon dioxide) and emission sources such as rice cultivation, agricultural soil, field burning of crop residue and urea fertilizer.

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.

전 지구적으로 댐 건설과 가정, 공업 및 농업 용수의 사용 등 인간의 영향으로 유출량, 지하수, 토양수분 등의 다양한 수문요소가 변화를 보이고 있다. 이러한 인간의 영향은 기후변화의 영향과 함께 수문요소에 주요한 동인으로 이의 영향을 이해하고 전망할 필요가 있다. 본 연구는 Inter-Sectoral Impact Model Intercomparison Project를 통해 이용 가능한 여러 글로벌 수자원 모형의 결과를 분석하여 기후변화 및 인간활동의 영향의 상대적 중요성 등을 분석하고자 한다. GFDL, HadGEM, IPSL, MIROC5에서 도출된 기후 시나리오를 기반으로 구동된 글로벌 수자원 모형결과를 살펴보고자 하며, 글로벌 수자원 모형은 CLM, H08, JULES 등을 포함한다. 본 연구에서는 증발산량, 토양수분, 유출 등의 시간 및 공간적 변화, 기후변화 및 인간 활동의 영향이 주요한 역할을 하는 지역 혹은 유역을 확인하는데 초점을 맞추고자 한다.

The purposes of this study were to examine the relationship between participation in sport for all, social support among the aged. To attain the goal of the study described above paragraphs, the older person resided in Seoul and Gyonggi, 2006 year were set as a collected group. Then, using the cluster random sampling method, finally drew out and analyzed 245 people in total. The result of reliability check up was here below; over Chronbach's ${\alpha}=.775$. To analyze materials, factor analysis, ANCOVA, multiple regression analysis were used as statistic analysis techniques. The conclusion based on above study method and the result of material analysis are below. Based upon the result of the study, the conclusions are the followings; First, participation experience of sport for all don't influence on the social support. Second, participation degree of sport for all influence on the social support.

소지역에서 직접(direct) 시계열추정을 할 수 있다면, 소지역들 추정에서 최적선형 불편예측량(BLUP)을 일반화 시킬 수 있다. 특히 조사에서 얻어지는 관측 값의 오차가 시간상으로 상관관계가 있다면 Kalman-Filter(K-F)기법이 사용 될 수 있다. 이 연구는 소지역의 실업자 수 추정에서 K-F기법으로 경제활동인구수를 이용하여 현 시점의 소지역 실업자 수를 예측함수(BLUP)를 통해 추정하였다. 그리고 단순 회귀분석 추정치와 비교하였다.

The purpose of this study is to develop a software program to diagnose and assess status of dietary intake obtained using 24-hour dietary recall method. This program consist of four functions. The first function is assessing tile general status of the body such as ideal body weight, obesity measure, activity expenditure energy and total energy requirement by the analysis of age, height, weight and the degree of activity. The second one is calculating the intake number of food classified by the food group and evaluating the status of food intake by comparing them with the number of standardized intake in recommended dietary allowances for Koreans,6th revision. Third one is calculating energy and nutrient intakes contributed by the food group in dietary intake and evaluating the status of dietary intake by comparing the nutrient intake with the recommended dietary allowance for Korean, especially calculating and evaluating the status of dietary fat intake. The fourth function is calculating and evaluating the status of nutrient intake and nutrients energy Percent contributed by three regular meals and at least one in-between-meal snack. The results are displayed as tabular forms and graphical forms on the computer screen.

댐 유입량의 구성을 이해하는 것은 직접유출과 기저유출의 특성에 따라 수자원확보, 물 공급, 관개용수, 수력발전, 생태계 서식지, 친수활동 등 계절별 댐 운영을 효율적으로 수행하는데 기여할 수 있다. 또한, 댐은 대부분 유역 상류에 위치해 있어 댐 유입유량에 있어 다른 수리구조물에 의한 영향이 상대적으로 작기 때문에 앞에서 제시한 인위적 영향을 제외한 기저유출분리를 수행 할 수 있다. 이와 관련하여 본 연구의 목적은 1)댐 유입량에 대한 연별, 월별 기저유출을 분석하고; 2) 유역 상 하류에 위치한 댐의 유입량에 대하여 기저유출 기여도를 비교하는 것이다. 두 개의 연계 댐에 대하여 인위적 영향이 적은 상류에 위치한 댐이 하류에 위치한 댐보다 Baseflow Index가 더 작은 결과를 보여주었다. 상류 수자원시설부터 인위적 방류는 하류의 댐 유입량의 Baseflow Index를 과다산정의 원인이 될 수 있다는 것으로 나타났다. 본 연구의 결과는 댐 유입량의 특성을 월별 연별로 분석함으로써 댐의 역할과 기능을 확대하고 효율적 상 하류 댐 연계운영에 기여할 것으로 기대한다.

Residential streets play an important role not only as a Place for moving but also as a place for social interactions among urban residents. Social interactions among urban residents are critical factor to draw sense of confidence and communality, and community spirit from the residents. Social interactions among community residents, however, are getting restricted severely by automobile traffic in the residential area. This study shows that the level of social interactions among the residents decreases substantially as traffic volume increases in the area. Other daily activities such as relaxing. playing with children, exercising, and doing small works in the street which can caused social interactions among the residents are also decreased as the volume of automobile traffic increases. Residents living in the area of heavier traffic volume perceive more strongly that automobile traffic is the major reason which deters them from interacting socially each other.

The purpose of this study was to investigate effects of physical activity and sedentary life in metabolically healthy obesity(MHO) and metabolically unhealthy obesity(MUO). A total of 1585 middle-aged obesity men and women participated in this study. The subjects were divided to MHO(n=840) and MUO(n=745) by metabolic syndrome markers(National Cholesterol Education Program-Adult Treatment Panel III). We analyzed measurement data using t-test. As results, physical activity and exercise participant between group had not significant difference in men subjects. But, in women subjects, total physical activity volume and muscle strength exercise participant between group had a significant difference. In conclusion, we suggest that physical activity and exercise participant are important factors affecting health status in the same level of obesity women.

This study aimed to examine the prevalence rate of metabolic syndrome according to milk and dairy products intake and physical activity in Korean adults. After adjusting the age and sex, which are confounding factors that may affect the disease were analyzed by logistic analysis to confirm their association with metabolic syndrome. The subjects included 444 males and 807 females, aged 19 to 64 years, from the data of 'The Korean National Health and Nutrition Survey 2016-2017'. Milk and dairy product intake and physical activity were significantly associated with metabolic syndrome (OR 1.85, 95% CI 1.13 - 3.15), and low HDL-cholesterol (OR 1.52, 95% CI: 1.07 - 2.18). The results of this study show that dairy intake and physical activity tend to prevent metabolic syndrome.
