This study aims to analyze the income structure, cost structure, and profit structure based on data related to the business performance of the boat seine fishery from 1990 to 2020, and to identify the direct and indirect factors affecting fishery profitability through panel regression analysis. The main analysis results are as follows. First, it was found that fish catch has a significant amount of impact on fishery profitability, which is a key factor in improving the profitability of anchovy boat seine fishery. Second, it is necessary to develop carbon-reduced fishing gear, develop fleet-reduced fishing gear, and improve the operating system in order to increase fishery profitability for the short run. Third, it is necessary to create and maintain sustainable profitability for the long run, the continuous fishing vessels buyback program, an active responses to climate change, and the follow-up investigations about marine aggregate extraction in the south sea EEZ are needed.

본 연구는 동백나무 재배에 대한 수익성을 분석하기 위해 수익성 분석지표인 NPV, B/C율, IRR을 적용하였다. 이를 위해 사업기간 30년 동안 수반되는 비용과 편익을 산정하였다. 특히, 편익은 현재 시장가격이 형성되어 있는 동백나무 종자만을 한정하여 산정하였다. 그리고 향후 임금상승과 동백나무 종자 가격 하락에 의한 수익성의 민감성을 분석하였다. 수익성 분석 결과, 사업 10년차에 NPV는 4,537,645원, B/C율은 1.084, IRR는 4.6%로 나타났다. 그리고 동백나무 재배기간이 장기화 될수록 사업의 수익성은 높아지는 것으로 나타났다. 또한, 임금상승과 가격하락에 따른 감응도 분석결과 동백 나무 재배에 대한 수익성은 임금상승에 따른 영향보다 가격하락에 따른 영향이 큰 것으로 나타났다.

This study is investigated the process of calculating the support service cost for the oversea plants which are rapidly increasing from domestic automobile companies and removing the corresponding value from the cost of the domestic production products. In order to calculate the service cost for oversea support cost, survey methods was used among various options and The rate of contribution to individual work was obtained through revision works. We conclude that about 25% of the indirect processing costs of domestic production products should be eliminated and replaced with the cost of overseas support services.

Calculating break-even price of calf production is closely associated with reproductive efficiency. To determine the price, we need data from reproduction records including number of claves weaned, number of cows exposed for breeding, and annual cash coast per cow, and average weaning or market weight of claves sold and retained. Unfortunately, the data were not available in Korea native cow (Hanwoo). To evaluate the performance and the price, we collected calving interval from about 60,000 cows for last 10 years and estimated reproductive performance. Calving interval was increased 4.3% and pregnancy rate was decreased about 1.4∼2.8% year-on-year. Increases in growth rates of number of cow and semen per calf supported the low reproductive performance. Finally, break-even price was calculated using estimated percent calf crop and demonstrated that growth rate of break-even price is larger than that of annual cash per cow, suggesting cow-calf profitability and financial efficiency in Korea native cow (Hanwoo) is getting worse.

Background : This study provides Profitability Analysis information on Baeksoooh (Cynanchum wilfordii), One of the Crops excluded from the production cost survey. and it will contribute to increase the income of farmers. The purpose of this study was to survey and analyse the farm business performance of new economic crops cultivated in small area. Method and Results : In this study, we selected Baeksoooh, which is also called Baekhasuo, as a subject of investigation, based on the roots of C. wilfordii Hemsley. We visited 20 farmers who cultivated Baeksoooh in Jecheon, we surveyed the quantity, price of farmhouse receipts, cost of each branch, the status of agricultural machinery and facilities, and We analyzed income, operating expenses, and income per unit area. and also We set up a proper management model. It can be cultivated in all regions of Korea, but it is the main production area of Jecheon in Chungcheongbuk-do under the cool climate conditions. Most are being traded for medicinal uses. Looking at the profitability per 10a by Baeksooh's business performance, The result of this study are follows as. In the case of the top 20% farms, the gross quantity of the C. wilfordii is 332 ㎏ per 10a, the gross income was 11,418, managing cost was 2,259, income was 9,158 thousand won per 10a. In the average farms surveyed, the gross quantity of the C. wilfordii is 205 ㎏ per 10a, the gross income was 4,611, managing cost was 2,418, income was 2,193, production cost was 3,169 and net income was 1,445 thousand won per 10a. In the lower 20% farms cultivation, the gross quantity of the C. wilfordii is 46 ㎏ per 10a, the gross income was 89, managing cost was 1,848, income was – 1.759 thousand won per 10a. The professional farm management scale based on Baeksoooh's income of 20 million won is 43.4 a, it can produce 890 ㎏ with 1,176 hours per years, and the income is 9,522 thousand won Conclusion : Because the Baeksoooh being processed and circulated as health functional food have raised questions about their feasibility, Production and consumption declined sharply. but Consumption is expected to increase gradually and it is likely to grow, but prices are expected to fluctuate. Therefore, The bottom 20% farmers should benchmark the top 20% farms and cultivate the appropriate scale. and It is necessary to cultivate in consideration of supply and demand of manpower as well as proper size and cultivation.

This paper aims, first to analyse the profitability of coastal passenger ships deployed on both subsidized and non-subsidized routes, ie competitive routes, in Korea, second to evaluate them by route, by ship type, and by ship size, and finally to identify whether the ships deployed on subsidized routes are justifiable to receive subsidy from the government. They are followed by the analyses on the profitability of all ships on the coastal routes and their dependence rate of subsidy. The research covers the period of 1995-1997. The research results say that 35% of the total subsidized routes has more than 90% of subsidy dependence rate and that some monopolized routes among subsidized ones with moderate rate of profitability need to be crossed out from the list of subsidy beneficiary. In addition, some ships deployed are not appropriate type in terms of characteristics of route and traffic. One of implications drawn from this study is that the government has to set up a watchdog to monitor subsidized routes, which enables to make them competitive and save the budget.
