Producing animal products from farm to table emits massive amounts of greenhouse gases (GHGs). Modified meal plans, mainly including vegetables and grains, have been recommended to reduce GHG emissions. However, these meal plans have not been developed with regard to the micronutrient content, but rather with regard to the energy requirements of grains and vegetables, which could result in a nutritional imbalance. For this reason, we investigated a common Korean suggested meal plan (SMP) from the National Institute of Agricultural Sciences, in which nutritional conditions were considered, and evaluated its GHG emissions using the Life Cycle Assessment Inventory Database and nutritional values. The SMP, which included meat, was based on the Korean Nutrition Society for adult men age 19 to 29, and was changed to a vegan meal plan (VMP). Animal-based protein sources were substituted for meat alternatives, such as beans and tofu, for which carbon footprint data was available. To compare the nutritional differences, the 9^th Korean Food Composition Tables I and II were consulted. To calculate GHG emissions, the carbon footprint data of the food was converted to a CO₂ equivalent (CO₂e) using a procedure from the Foundation of Agriculture Technology Commercialization and Transfer. It was found that GHG emissions per calorie were 18% lower for the VMP when compared to the SMP. However, if GHG emissions per total amino acids were evaluated, the VMP GHG emissions per total amino acids were 0.12 g CO₂e/mg, while the corresponding value for the SMP was 0.06 g CO₂e/mg. The Korean daily meat intake reported by the Korea Agricultural Statistics Service was 37.1% lower than in the SMP, but when converted to a protein intake the figure was 17.0% lower. It was found that each SMP resulted in more GHG emissions than the VMP, but when considered as GHG emissions per total amino acids, the opposite pattern was apparent. There is a need to conduct more detailed studies of the variation in GHG emissions with different meal plans, using the daily meat intake per person.

This paper presents optimal accelerated life test plans with different censoring times for exponential, Weibull, and lognormal lifetime distributions, respectively. For an optimal plan, low stress level, proportion of test units allocated and censoring time at each stress are determined such that the asymptotic variance of the maximum likelihood estimator of a certain quantile at use condition is minimized. The proposed plans are compared with the corresponding optimal plans with a common censoring time over range of parameter values. Computational results indicate that those plans are statistically optimal ones in terms of accuracy of estimator when total censoring times of two plans are equal.

We defined life style as something that every members of society have in common. These social and cultural environments build up not only society group or every individual's expectation but also its own life style. In that way, these social and cultural environments leads to particular consumer behavior pattern in this food-service industry. So we regard next generation's trend which consists of rational consumers as important indicator when we make future's plan in foodservice industry. We consider smart map which needs rational and continuous consume pattern as the construction of next generation's main consumer class. Therefore, this study tried to develop of color and image marketing strategies to attract LOHAS and nomadic consumer.

As the life expectancy increases resulting in the aged society, the post-retirement life became one of the most important concerns of people. The long-term investment vehicles such as retirement savings and pension plans have been introduced to meet such demand of society. This paper examines the impact of asset allocation strategies on the long-term investment performance. Because of the unusually long investment horizon and the compounding effect, a suboptimal asset mix in a retirement plan can be a very costly and irreversible mistake. Instead of relying on anecdotal evidence to evaluate the merits of different allocation strategies, this paper performs various tests including stochastic dominance tests using both actual data and Monte Carlo simulated data that best fit the historical experience. The results indicate 1) the long-term investments perform better than the short-term investments, 2) the optimal asset allocation strategy for the long-term investments should be highly equity dominated.

BACKGROUND: Most lakes have increased concerns about water pollution due to the inflow of non-point sources caused by human activities. Therefore, the lake water quality survey was conducted in order to propose effective plans for water quality management by analyzing the characteristics of lakes and the change of water quality. METHODS AND RESULTS: In order to investigate the physicochemical water quality in Daedong lake, water quality analysis was undertaken from July 2018 to June 2019. Water temperature was ranged from 7.8 to 34.3℃ and pH varied from 6.9 to 10.2. The concentration of Dissolved oxygen, Suspended solid, Biochemical Oxygen Demand (BOD), and Chemical Oxygen Demand (COD) were 5.6 ~ 17.2 mg/L, 2.4 ~ 35.3 mg/L, and 4.5 ~ 15.1 mg/L, and 0.9 ~ 2.8 mg/L, respectively. The Total Nitrogen (T-N) concentration ranged from 0.974 ~ 2.126 mg/L, and Total Phosphorus (T-P) concentration ranged from 0.014 ~ 0.057 mg/L. The Chlorophyll-a (Chl-a) ranged from 2.7 ~ 37.9 mg/㎥. Through Carlson TSIm assessment using T-P and Chl-a results, evaluating trophic state, Daedong lake was evaluated as mesotrophic. CONCLUSION: Water pollution management plan needs such as nutrient removal technology and nonpoint source management for prevention of eutrophication in Daedong lake.

Purpose: The purpose of this study was to analyze the factors affecting those commitment to a plan for exercise among Korean with chronic diseases by Pender's health promotion model. Methods: The participants in this study were 315 Korean adults over 18 years of age with chronic diseases who were recruited in hospitals or public health centers in Korea. The instruments used in this study were individual characteristics instrument, Rosenberg's self-esteem scale, Ware's perceived health status, Profile of Mood States and Pender's commitment to a plan for exercises scale. Results: The results of analysis showed that Korean adults with chronic diseases were perceived with relatively low commitment to a plan for exercise while they were perceived with moderate self-esteem, health status, and mood. There were significant differences in the commitment to a plan for exercise according to education level and economic level. The positive relationship between self esteem, perceived health status, and commitment to a plan for exercise were significantly correlated. The experience for exercise was the most influential variable on commitment to a plan for exercise accounting for 40.3% among Korean with chronic diseases. Conclusion: For planning a targeted strategy to increase regular exercise among Korean adults with chronic diseases, nurses have to assess the prior experience of exercise of them. These nursing activities lead to improve their quality of life and encourage to control their symptoms.

이 연구의 목적은 한국의 임정에 큰 영향을 끼친 "조선임정계획(朝鮮林政計劃)"의 요존국유림 관련부분을 중심으로 하여 1926년부터 1936년까지의 일제의 한국 국유림정책을 파악하고자 하는 것이다. 이를 위해 동시기 국유림정책을 수립하는데 중요한 역할을 담당하였던 조선임정계획(朝鮮林政計劃)의 계획과 실적을 비교하여 그 성격을 도출하였다. 조선임정계획은 1)제1차 세계대전 이후 목재수요의 급증에 대비하기 위해 2)분산된 국유림관리조직의 통합을 위해 3)일본에서의 영림국서제도(營林局署制度)의 설치에 영향을 받아 만들어졌다. 이 연구를 통해 1)수입의 보속만을 추구한 사업안 2)10년만에 두배로 늘어난 벌채량 3)벌채적지의 13%만의 인공조림 4)산림축적의 감소가 대부분 국유림에서 이루어졌다는 점 5)영림서의 계속적인 축소 통폐합 6)국유림에서의 막대한 이득 등을 확인할 수 있었다. 즉 이러한 임정계획 및 실적을 통해, 1926년부터 1936년까지의 기간은 '보속적인 산림경영'을 추구했다기보다는 증벌을 통한 제국주의의 초과이윤을 실현한 '국유림 수탈정책'의 실현에 그 목적이 있었다는 것을 알 수 있다.
