This paper first makes a survey of fishing household economy which possess fishing boats under 10 gross Tons by a questionnaire, and makes a comparative study of major indicators of fishing household economy between Korea and Japan, and finally suggests some policies for the fisheries management. Major indicators are the status of fishery household members, number of fishing boats which possess, fisheries incomes, fishing household incomes, side business incomes of fishing household, disposal incomes, living expenses, sufficient degree of living cost, average propensity to consumption and so on. Some policies for improvement in fishing household incomes are suggested in the paper as follows: ⑴ Form a policy similar to a project aiming for increasing the income of fishermen so that the side business income will also increase. ⑵ The point of view in tracing origin of low productivity. ⑶ It has drawn up a plan to encourage saving after analyzing the cause of high propensity to consumption. ⑷ The paper is aimed to collect basic statistical materials for fisheries administration.

This paper investigates whether an inverted U relationship between pollution and economic development could be found in the Seoul metropolitan region using a panel data for the period of 1985~1999. We uses a model with a more flexible random coefficients specification which allows for a greater degree of regional heterogeneity. The emissions of sulfur dioxidetotal($SO_2$), suspended particulates(TSP), nitrogen dioxide($NO_2$), and carbon monoxide(CO) were selected as four major pollutants. We found that the emissions of these pollutants per capita except sulfur dioxidetotal exhibited inverted U shapes with per capita gross regional domestic product (GRDP). We also noted that the turning points for Seoul metropolitan region occured at a range of incomes, from $3,000 to $5,000 per capita.

This study was aimed to analyze the increased forestry incomes by combining timber production and wood processing, which is one of 6th industrialization types in Korean forestry. The selected household has been engaged in forestry for two generations and they produce timber and associated wood products in their own facility. The wood products include dimension lumber, interior wood material, cutting board, and cube chips, the household also utilize logging and sawmill residues as well as seed and seedlings as by-products. Incomes and expenses that have been incurred on individual processes of the sequential timber production and wood processing were surveyed, and we analyzed the economic outcomes of entire business. The results of this study indicate that the gross income of the household is 122.3 million Korean won and the net income is 93.6 million Korean won. The net income of the household is approximately 2.8 times higher than the average net income of whole households in the forestry of Korea in 2016, which is approximately 4.3 times higher than that of households that have been particularly engaged in timber production over the country. We found that the 6th industrialization by combining the two sequential processes creates approximately 3.2 times as much added value compared to the case relying on timber production only.

High quality meteorological information is the typical product of service business industry which can offer the investment initiative by reducing the uncertainty and by activating other related industries. It requires a high level of meteorological technology and of ability to transform such technology as merchandising products. According to the analysis of the WMO data, the level of Korean meteorological technology is comparable to that of the nation with $17,500, GDP per head. However, the income of the meteorological business agent earns in Korea is 8 billion 4 hundred million won which is less than a tenth of that made by the US or Japan. The potential for such business field in Korea will be strong enough, if one can overcome such weak points. In addition, the efforts made by the government to advance the meteorological technology have been actualized gradually. Korean government will have a chance that is comparable to offering jobs for 20,000 unemployed by creating incomes of 40 billion won by meteorological technology as a sustained economic growth engine. It is proposed that government stimulate demand and supply by focusing on sales quantity than the price. The key points for creating the new demand are marketing and outsourcing of weather and climate information by maintaining the cooperative relationship between private and public sector.

Estimating fishing capacity is one of current hot issues in the international fisheries. It is because that increased fishing capacity has caused not only fish stocks to be reduced, but also additional fishing costs to be incurred without additional incomes, which resulted in decrease of economically viability of fisheries. In order to solve this problem, FAO adopted 'the International Plan of Action for the Management of Fishing Capacity' in 1999 and recommended that member countries to measure fishing capacity and to implement the domestic action plan to reduce excess fishing capacity. This study is aimed at assessing fishing capacity of the octopus coastal trap fishery(OCTF) using data envelopment analysis(DEA) which is a method recommended by FAO. The DEA results on 10 individual OCTF vessels showed that the capacity utilization(CU) was a 0.93 on average, indicating some differences in CU among vessels(0.79-1.0). In addition, results of the sensitivity analysis revealed that under the current level of catch, the gross tonnage, horse power, days fished, and traps per trip could be reduced by 35%, 33%, 16%, and 18% on average, respectively.

본 연구는 한국노동패널을 이용하여 지니계수를 분해와 패널분석을 통해 부동산소득이 가구 소득불평등에 미치는 영향을 실증분석하였다. 공간적 범위를 전국, 수도권, 비수도권으로 나누었고 글로벌금융위기 전 후로 기간을 살펴보았다. 분석결과, 첫째, 전기간을 전국, 수도권, 비수도권으로 나누어 지니계수 분해를 이용해 소득 원천별로 나누어 살펴본 결과, 총소득에서 전국과 수도권은 부동산소득이 차지하는 절대적, 상대적 기여도가 가장 크게 나타난 반면 비수도권은 근로소득이 가장 크게 나타났다. 또한 전국과 수도권은 부동산소득이 가구 소득불평등을 가장 심화시키는 것으로 나타났다. 둘째, 금융위기 이후기간이 이전기간에 비해 가구 소득불평등에 부동산소득이 영향을 덜 미치는 것으로 나타났다. 이는 글로벌금융위기 이전에는 부동산가격이 급등을 하여 가구 소득불평등을 심화시켰으나 이후기간에는 가격하락으로 수익성이 악화돼 일시적으로 약화된 것으로 판단된다. 셋째, 상관관계분석에서 가구주 연령이 높고 고졸미만의 학력의 가구는 다른 가구에 비해 가구총소득이 낮을 것이며, 원천별 소득 특히 근로소득이 높을수록 가구 총소득이 상대적으로 높았다. 넷째, 수도권과 비수도권 지역으로 구분한 가구소득 결정요인을 패널분석한 결과를 비교하면 근로소득, 금융소득과 기타소득의 영향은 비수도권지역이 수도권지역에 비해 높은 반면 부동산소득의 영향은 수도권지역이 비수도권지역에 비해 높은 것을 알 수 있다. 정부는 소득불평등을 줄이기 위해서 고소득층에 세금을 강화하고 저소득층에 대한 세금 감면을 할 수 있는 정책적 배려가 필요하며 다양한 일자리 창출을 위한 노력을 기울여야 한다. 또한 자산보유를 통해 창출하는 소득의 비중이 높아질수록 소득불평등이 악화하는 경향이 있는 만큼 부동산가격 안정화에 중점을 두면서 지역별 차별성을 두고 정책을 수립 집행할 필요성이 있다.

The objectives of this study were to estimate genetic parameters for the carcass price and carcass traits contributing to carcass grading and to investigate the influence of each carcass trait on the carcass price using multiple regression and path analyses. Data for carcass traits and carcass prices were collected from March 2003 to January 2009 on steers of Korean cattle raised at private farms. The analytical mixed animal model, including slaughter house-year-month combination, linear and quadratic slaughter age as fixed effects and random animal and residual effects, was used to estimate genetic parameters. The effects of carcass traits on the carcass price were evaluated by applying multiple regression analyses. Heritability estimates of carcass traits were $0.20{\pm}0.08$ for carcass weight (CWT), $0.33{\pm}0.10$ for back fat thickness (BFT), $0.07{\pm}0.05$ for eye-muscle area (EMA) and $0.25{\pm}0.10$ for marbling score (MS), and those of carcass prices were $0.21{\pm}0.10$ for auction price per 1 kg of carcass weight (AP) and $0.13{\pm}0.07$ for total price (CP). Genetic correlation coefficients of AP with CWT and MS were $-0.35{\pm}0.29$ and $0.99{\pm}0.04$, respectively, and those of CP with CWT and MS were $0.59{\pm}0.22$ and $0.39{\pm}0.29$ respectively. If an appropriate adjustment for temporal economic value is available, the moderate heritability estimates of AP and CP might suggest their potential use as the breeding objectives for improving the gross incomes of beef cattle farms. The large genetic correlation estimates of carcass price variables with CWT and MS implied that simultaneous selection for both CWT and MS would be also useful in enhancing income.
