Timing of weaning is later in Korean rural and lower urban classes compared with middle and upper classes. Weaning after the international standard of six months of age has adverse effects on the growth rate of children. This occurs because supplementary foods are not provided for the child during the weaning period; rather, the infant goes directly from nursing(or bottle feeding) to the cereals and solid foods of the adult diet. Consequently, all nutrient and calorie intake, with the exception of thiamin, in Korean rural children had not yet attained the Recommended Dietary Allowance (RDA). This situation bas created an urgent need for easy to prepare, low priced. highly nutritious supplementary foods. The research team of Yonsei University developed 3 formulas prepared from rice, soybeans, sesame, dry skim milk and fish which are all plentiful and inexpensive items in Korea. A proximate analysis and amino acid determination were performed on three formula. These formulas were prepared and used as exprimental diet for an animal assay. In the animal assay, growth rate, PER evaluated and biochemical analyses were also carried out. A safety storage assay and the cost evaluation were also conducted.

The evolution of multi-family housing in Cheongju can be divided by four stages which are a introduction period from 1972 to 1980, a popularization period from 1981 to 1989, a expansion period from 1990 to 1997, and a stagnation period after 1998. In the introduction period, the multi-family housings were mainly low-rise buildings because a government policy which focused on extension of the apartments for the low-income influenced multi-family housing constructions. During the popularization period, the multi-family housings were still low-rise but houses in various sizes were introduced. That was because the Housing Site Developments were started and private companies' participations followed them increasingly. As a result of vigorous participations of private companies and massive developments of housing sites, the multi-family housings in the expansion period started to show constructions of complex and trends of high density and high rising. Finally, in the stagnation period, a rate of the supply of the small houses, whose size was below $60m^2$ of exclusive, area was increased and extreme high-rise apartments emerged. High rising and density were the mainstream of the construction concepts. During this period, the growth of multi-family housing marked low. The reason was that a downturn in economy led private companies to shrink their constructions.

Eco-efficiency which is calculated by dividing economic productivity by the environmental load was made by synthesizing eco and efficiency from ecology and economy, proposed by World Business Council for Sustainable Development in 2000. Eco-efficiency by connection of resource efficiency with resource intensity is used as an indicator for evaluating green growth for minimizing the impact on the environment and achieving economic development as well by means of efficient use of resources. This research analyzes eco-efficiency with the case of organic agriculture promoted as a key green growth policy. Thirty questionnaires for farmers producing organic rice in Hongseong-gun, Choongcheongnam-do were used for the analysis. Eco-efficiency was measured by means of the amount of used nitrogen with respect to the amount of income, and was represented that organic agriculture was 32.0 higher than conventional agriculture. The analytical result of technical efficiency, using the (Data Envelopment Analysis (DEA) model showed that it is 0.765 which has a possibility of 21% in management improvement, and higher eco-efficiency was with higher technical efficiency. The analytical results showed that an organic agriculture contributes to green growth more than conventional agriculture. In addition, higher technical efficiency groups exhibited higher eco-efficiency indices.

Climate change with extreme hydrological events has become a significant concern for agricultural water systems. Climate change affects not only irrigation availability but also agricultural water requirement. In response, adaptation strategies with soft and hard options have been considered to mitigate the impacts from climate change. However, their implementation has become progressively challenging and complex due to the interconnected impacts of climate change with socio-economic change in agricultural circumstances, and this can generate more uncertainty and complexity in the adaptive management of the agricultural water systems. This study was carried out for the agricultural water supply system in Seongju dam watershed in Seonju-gun, Gyeongbuk in South Korea. The first step is to identify system disturbances. Climate variation and socio-economic components with historical and forecast data were investigated Then, as the second step, problematic trends of the critical performance were identified for the historical and future climate scenarios. As the third step, a system structure was built with a dynamic hypothesis (causal loop diagram) to understand Seongju water system features and interactions with multiple feedbacks across system components in water, agriculture, and socio-economic sectors related to the case study water system. Then, as the fourth step, a mathematical SD (system dynamics) model was developed based on the dynamic hypothesis, including sub-models related to dam reservoir, irrigation channel, irrigation demand, farming income, and labor force, and the fidelity of the SD model to the Seongju water system was checked.

Purpose: The improvement of the social security system can greatly affect residents' future uncertainty, and it is important to study the relationship between public pensions and household consumption. Research design, data and methodology: Using the 2018 China Household Panel Survey (CFPS) data, the instrumental variable method is used to analyze the impact of pension insurance on urban residents' consumption. Results: The results of the study show that there are differences in the impact of three different pension insurance systems on household consumption. The pension insurance for public sector significantly boosts household consumption, and having a pension insurance for public sector can increase household consumption by 7.7%. The pension insurance for enterprise employee will reduce household consumption, but this is only significant for urban households. The pension insurance for urban and rural residents has a negative impact on household consumption. For the 16- to 39-year-old group, having a pension insurance for urban and rural residents will reduce household consumption by 5.7%. At the same time, household income, assets, scale, and education level will positively stimulate household consumption. Conclusions: The study reveals varying impacts among different pension types, highlighting the need for optimizing social security schemes to incentivize higher consumption rates.

The mature Bombyx mori silkworm is recognized as a rich source of several nutrients. A unique steaming process has been developed to enhance the palatability of Bombyx mori silkworm and make it more convenient to consume. Additionally, it has also been freeze-dried into a powder form, which is recognized as a nutritional supplement with many health benefits. Steamed and Freeze-dried Mature Silkworm Powder (SMSP) is said to offer a wide range of benefits, including longevity, improved athletic performance, prevention of alcohol-induced liver fibrosis or tumors, amelioration of fatty liver, prevention of peptic ulcers, regulation of melanin production, and mitigation of Parkinson's and Alzheimer's diseases by improving cognitive function. The nutritional composition of SMSP is particularly high in glycine, alanine and serine. This review aims to summarize the molecular mechanisms underlying the diverse effects induced by these key components of SMSP. Such elucidation will enhance the credibility of future studies on SMSP, which will require more comprehensive analyses. It appears that SMSP represents a natural health supplement that could have a positive impact on global human health while increasing income.

This study investigates the cultivation processes of major nuts and fruits such as Ginkgo biloba L., Vitis coignetiae, Actinidia arguta Planch, Rubus coreanus Miq., and Rubus crataegifolius and analyzes standard income in order to provide foundational data necessary to make reasonable policies related with the criteria of compensating the loss of forest products or diagnosis of forestry management. According to the research results, the types of cultivation by items can be largely divided into open field culture and mountainous culture. Regarding the average annual income per unit area (3.3) by items, the open field culture of Ginkgo biloba L. was 1,060 Won, mountainous culture of Ginkgo biloba L. was 618 Won, open field culture of Vitis coignetiae was 5,891 Won, mountainous culture of Actinidia arguta Planch was 8,113 Won, open field culture of Rubus coreanus Miq. was 14,701 Won, and open field culture of Rubus crataegifolius was 17,482 Won or so; thus, the average annual income of Rubus coreanus Miq. and Rubus crataegifolius was very higher than that of the other items. In particular, because the production of Rubus crataegifolius starts two years after the planting and they rely on family labor mainly for the cultivation, the expenses for employment and labor were analyzed to be low. In addition, the analysis shows that at most of the nuts and fruits cultivation, initial investment costs for facilities or seedlings occupy a great part as about 30% averagely out of the management cost, so it is thought that the government should provide proper support to vitalize the cultivation.
