Until now, we recognize that water supply is a public sector rather than business sector in Korea. In spite of the general recognition, water supply sector has an important role within the national economy as an industry. This study try to analyze the current status of water supply sector as a industry with input-output analysis. As we expected, water supply sector is still minor as an industry sector. However, this is not because water supply sector is not important as a industry, but because the price of water too low or free. With regard to the water price impacts, our results show that the 10% increasing water price has only increased 0.01% of the general price level, which is neglectable. To have a competitiveness as a industry, water sector should be reevaluated based on its socioeconomic value. Government policy for water supply sector should achieve two purposes; the one is for as a public service, the other is for the setting new paradigm as an industry.

The purpose of this study is to draw up a plan for improving working conditions of distant water fishing vessel crew in order to revitalize the declining distant water fishing industry. Land-based employment has increased as the result of industrialization, which in turn created shortage in marine crew supply for distant water fishing vessels. Pressure on increasing wages for sea farers is put on the industry for this reason, making the labour market in the distant water fishing industry tougher and tighter. Multiple issues have yet to be addressed for distant water fishing vessel crew. They suffer from excessive work compared to other industries. Crew management is another issue, as sea farers face poor labour conditions, working on board vessels in a collective way where no autonomous actions are allowed. Other issues include unqualified crew supply, increasing ratio of labour costs for crew to sales, and intensified implications of labour unions, which are as well making crew supply difficult as a whole. To this end, more well-qualified workers should take part in production operations in the distant water fishery. Both wage increase and working condition improvement should be achieved in order to strengthen motivation towards qualified sea farers. Sustainable crew supply can be achieved when working environments, gender-based working conditions, welfare are prioritized and improved as a whole.

오늘날의 시대는 블랙골드(black gold)시대를 벗어나 이제 블루골드(blue gold)의 시대가 도래되었다고 할 수 있다. 물에 대한 중요성이 증가되는 가운데, 물 산업의 발전을 위한 지원 및 정책이 제시되고 있다. 물 산업은 공공서비스이지만, 불균형한 공급으로 인한 문제점들이 존재하며 이를 해결하기 위해서 공공서비스의 민영화라는 주제와 관련해 가장 민감하고 관심이 집중된 분야라고 할 수 있다. 우리나라도 이러한 물 산업의 민영화에 대한 주제가 언급되면서 현행 수도법에 근간한 민영화 운영방식 중 하나인 전문기관(한국수자원공사)에 의한 민간위탁이라는 방식으로 공공서비스의 효율성을 높이고자 사업을 진행 중에 있다. 따라서 본 연구에서는 지방상수도 민간위탁 운영을 실행 중인 18개 지역의 위탁사업소들을 대상으로, 2012년부터 2014년까지의 데이터를 바탕으로 하여 민간위탁운영에 대한 효율성 및 생산성 분석을 실시하고자 한다. 본 연구의 효율성 분석결과, 3개년 동안 18개의 위탁기관 중 10개 기관이 효율적인 기관으로 나타났으며 생산성 변화에 대한 분석을 실시한 결과, 1기(2012-2013년)에서 2기(2013-2014년)로 넘어가는 동안 생산성이 감소된 것을 확인할 수 있었다. 이러한 생산성에 영향을 미치는 원인은 누수율과 원수의 유효이용률로 선정하였고 누수율의 경우 생산성에 부(-)의 영향을 미치는 것으로 나타났고 원수의 유효이용률의 경우, 생산성에 정(+)의 영향을 미치는 것으로 나타났다. 따라서 본 연구는 현 수도사업의 문제점을 해결하기 위한 해결책에 대한 효율성과 생산성을 분석하였다는 점에서 기존의 수도사업과 관련된 연구들이 제시하지 못한 시사점을 지니고 있다고 할 수 있다.

Recently water demand is increasing as the industry prospers. The increase of water demand is followed by the increase of wastewater discharge which pollutes rivers and ground water extensively. These rivers, reservoirs and ground water are sources for drinking water and their contamination affects the quality of water supply and other potable water. In Korea there are 776 water treatment plants which supply drinking water from main rivers or reservoirs. Rivers are the biggest water source for drinking water is being contaminated, the innovation of treatment process is needed. The construction and operation of water supply facilities is under the control of the Ministry of Construction and the water supply offices of cities and provinces. However, drinking water quality is under the control of the bureau of sanitation in the Ministry of Health and Social Affairs. There are 33 items in drinking water quality standards of Korea. Trihalomethanes, Selenium, Diazinone and other three of pesticides have been included lately, The Ministry of Health and Social Affairs is planning to enhance. the level of $VOC_S$(Vola-tile Organic Compounds) standard. Drinking water quality standard is the goal to protect the quality of supply water and ground water. In order to protect the source water from domestic or industrial water, technological improvement and adequate investment should be urgently made. The ultimate goal of drinking water quality is safety and health of consumers. The more stringent the standard are, the better the water quality will be. As the drinking water quality standards become more stringent this year, various and positive solutions by the authorities concerned must be prepared.

Built-out issue of copper processing appearing recently in the Paldang watershed is a critical problem to deteriorate the basic framework of national water management policy as well as to be simply a copper-related problem. Up to now, Korea government has invested hard and relevant upstream areas have been victimized readily in a variety of field to comply its goal of 'Safe Water Supply'. Because of the reason, the desirable water quality level of the Paldang watershed has been maintained regardless of its dense population. Paldang drinking water management policy is based on residents' understanding which is considered as a 'social capital'. The issue raised in the aspect of water quality management policy should be reviewed on the basis of the 'social capital' concept. One regarding semiconductor industry as a potential industry to export many products in 10 years insists that the industry not be a simple private business but be a prominent part for national competitiveness. There is no doubt about this opinion. However, a nation should support environmental right-to-life of its people prior to any other tasks. In other words, it is really risky to give up people's right due to economic benefits. Therefore, it should not happen to trade 'life', the dignity of man, with national competitiveness which is likely to be preferred in these days. In addition, coherent policy not to destroy 'social capital' promoting Paldang drinking water resource management policy should be maintained.

This study contemplated domestic and other country's effluent limitation standards and suggested a methodology to establish technology-base limitation value. Current effluent limitation regulates industrial point sources discriminated by discharge flow rate and by regional distinction in Korea. Discharged $BOD_5$ load from large-scale plants(flow rate above $2,000\;m^3/day)$ exceeds 50% of overall industrial wastewater, which present rationale for discrimination based on plant size. However, regional distinction and pollutant- specific regulation might be insufficient to meet practical effectiveness of wastewater management policy, due to the nearly same limitation. Water quality data and treatment methods were investigated in hospital industry. And their distribution of effluent $BOD_5$ concentrations was statistically analyzed to suggest limitation value. Effluent $BOD_5$ concentrations showed lognormal distribution and $95^{th}$ percentile was corresponded to 87.9 mg/L, which could be suggested as tentative effluent limitation in hospital industry. The $95^{th}$ percentile of log-transformed distribution showed similar value of 86.5 mg/L. This study demonstrated reasonable methodology for establishing effluent limitation reflecting wastewater characteristic and treatment technology in separately categorized industry.
