The traditional von Thunen model has various shortcomings. Perhaps the greatest dificiency is the model's sole emphasis on the production side of the economy;that is, the agricultural markets are rarely closed for demand. In thes paoer a closed model for a three-activity, two-dimensional economy is developed. Equillibrium solutions are generated for prices, land areas, and outputs. Comparative static analysis then follows. Attention is next given to a maximum expected-return model under environmental uncertainty. Land uses for the traditional model and the closed model are then compared.

The price determinant for land investment depends on the internal information process and subjective decision making by management in general. Accordingly, the systematic frame to determine the feasibility of investment price to the public residential land for multi-housing development by private sector has not been proposed. The purpose of this study is to explore the frame to determine the investment price for public residential land from the perspectives of land attribute and apartment market factor. Multiple regression has been implemented to confirm the eligibility of proposed model. Research findings indicate that the land area, floor area ratio, coverage ratio, location have been identified as the total land cost determinant, and for the determinants for floor area land cost, the ratio of apartment, sale price, rent price, etc, have been identified. This research intends to provide the basis for land providers to predict the land value as a raw material in market and present the indicators for land buyers to review the price adequacy for the investment.

Combining recent advances in causal flows with time series analysis, relationships among eight North American natural gas spot market prices are examined. Results indicate that price discovery tends to occur in excess demand regions and move to excess supply regions. Across North America, the U.S. Midwest region represented by Chicago spot market is the most important market for price discovery. The Ellisburg-Leidy Hub in Pennsylvania is important in price discovery, especially for markets in the eastern two-thirds of the U.S. Malin Hub in Oregon is important for the western markets including the AECO Hub in Alberta, Canada.

"국가를 당사자로 하는 계약에 관한 법률" 시행령 제9조 1항 제3호 및 같은 법 시행규칙 제5조 제2항에 근거 전기공사의 예정가격의 결정기준은 (1)거래실례가격 (2)표준품셈 (3)표준시장단가 (4)견적가격 등 4가지 방법을 사용하고 있다. 특히 표준시장단가제도는 이미 수행한 공사의 계약단가만을 고려하여 발표하는 "실적공사비"제도를 계약단가, 입찰단가, 시공단가 등을 고려한 "표준시장단가"제도로 2015년 3월 1일부로 개정되었다. 제도는 시행되었으나 표준시장단가의 산정기준, 절차 및 방법 등 세부적인 제도가 미흡한 상황이다. 따라서 과거 실적공사비 산정방식을 검토하되, 계약단가, 입찰단가, 시공단가 등을 고려한 합리적인 표준시장단가의 산정방식을 제시함으로써, 예정가격결정시 적정공사비를 확보하고, 원 하도급간의 거래가격 투명성 및 객관성을 통해 전기공사의 품질 및 안정성이 확보될 것으로 사료된다.

발전원별 경쟁(신규 발전소 건설이 시장 가격에 의해 결정)을 도입한 미국의 캘리포니아주에서는 최근 심각한 전력 공급문제가 발생하였다. 미국과 같은 발전원별 경쟁을 도입한 우리나라의 경우에도 전력시장에서의 시장가격을 예측하고 이에 따른 신규 발전소 건설을 예측하여 전력 공급의 안전성을 검토할 필요가 있으며 또한 원자력이나 유연탄의 공급이 이러한 전력 공급의 안정성에 어떻게 기여할 수 있는가를 검토하는 것은 의의 있는 일이다.(중략)

Objectives: The purpose was to identify the ingredients that are usually surveyed for assessing real prices and to present the demand for such surveys by nutrition teachers and dietitians for ingredients used by school foodservice. Methods: A survey was conducted online from December 2019 to January 2020. The survey questionnaire was distributed to 1,158 nutrition teachers and dietitians from elementary, middle, and high schools nationwide, and 439 (37.9% return rate) of the 1,158 were collected and used for data analysis. Results: The ingredients which were investigated for price realities directly by schools were industrial products in 228 schools (51.8%), fruits in 169 schools (38.4%), and specialty crops in 166 schools (37.7%). Moreover, nutrition teachers and dietitians in elementary, middle, and high schools searched in different ways for the real prices of ingredients. In elementary schools, there was a high demand for price information about grains, vegetables or root and tuber crops, special crops, fruits, eggs, fishes, and organic and locally grown ingredients by the School Foodservice Support Centers. Real price information about meats, industrial products, and pickled processed products were sought from the external specialized institutions. In addition, nutrition teachers and dietitians in middle and high schools wanted to obtain prices of all of the ingredients from the Offices of Education or the District Office of Education. Conclusions: Schools want to efficiently use the time or money spent on research for the real prices of ingredients through reputable organizations or to co-work with other nutrition teachers and dietitians. The results of this study will be useful in understanding the current status of the surveys carried out to determine the real price information for ingredients used by the school foodservice.
