목질계 바이오매스는 신재생에너지원에 비해 국내 잠재량이 가장 풍부한 에너지원 가운데 하나이다. 그러나 주요 공급원인 간벌목 부산물의 10%, 폐목재의 1/3 정도만 활용되고 있다. 따라서 향후 관련법제도 개선 및 지원을 통해 바이오매스의 에너지 활용도를 높일 필요가 있다. 목질계 바이오매스를 이용하여 에너지를 생산할 경우 잠재적 기여도는 2005년 신재생에너지 공급량의 29.4%에 달하며, 신재생에너지의 일차에너지 소비대비 2.13%에서 2.76%로 증가시킬 수 있는 잠재력을 갖고 있다. 본 연구는 전국 16개 시도별로 잠재되어 있는 목질계 바이오매스 생산 가능량을 추정하고 이를 바이오열병합발전소의 주연료로 이용할 경우 지역별 경제적 파급효과를 분석해 보았다. 그 결과 경기, 서울, 전남, 경북, 강원, 충남 등에서 파급효과가 크게 나타났다. 지역별 파급효과를 합할 경우 부가가치 파급효과가 15,736억원, 고용효과가 2,630명으로 나타났다.

The Fukushima nuclear accident in 2011 had an extensive impact on the national electricity plans. This paper outlines alternative electricity scenarios that meet the goals of nuclear phase-out and greenhouse gas (GHG) emission reduction. This paper also analyzes the results of each scenario in respect to the electricity mix, GHG emissions, costs and employment effects. The Long-range Energy Alternatives Planning system (LEAP) model was used to simulate the annual electricity demand and supply system from 2011 to 2030. The reference year was 2009. Scenarios are reference (where existing plans are continued), A1, A2, B1, B2, and C2 (where the levels of demand management and nuclear phase-out are different). The share of renewable energy in the electricity mix in 2030 for each scenario will be increased from about 1% in 2009 to 8% in the reference scenario and from 11% to 31% in five alternative scenarios. Total cumulative cost increases up to 14% more than the reference scenario by replacing nuclear power plants with renewable energy in alternative scenarios could be affordable. Deploying enough renewable energy to meet such targets requires a roadmap for electricity price realization, expansion of research, development and deployment for renewable energy technologies, establishment of an organization dedicated to renewable energy, and ambitious targets for renewable energy.

As the education of maritime college has a characteristics of seafaring professional institutions, the potential benefit following from the employment of seafarers would put substantial impact on it. The socio-economic position of seafaring occupations has been deteriorated considerably with changes of ship's auto-mation, specialisation and low cost operation management of shipping companies through severe internatio-nal competitions. The quality and number of applicants for the maritime college has declined and most students have no hopes for the study of seafaring subjects which followed bewildering in their college days. However, the demands for seafarers are fairly large from the viewpoint of national maritime industry. The maritime institutions should not only meet these demands but also revitalise students by reforming the educational contents. The contents should be influenced by the social approach to educational needs in particular maritime shore-oriented subjects. The maritime education is no more restricted to the sea, it covers the land based world of the maritime industry as well. The new contents will lead the maritime educated students to the shore-based occupa-tions after finishing their seafaring if they want to. This may not only make ways to the maritime educa-tion fruitable, but also the students have a zeal and hope for the subjects taught.

The purpose of this study was to investigate the discriminative factors of on-line consumer satisfaction. Data were obtained from an online questionnaire survey with 1089 online shoppers who had the experience of either purchasing or visiting a fashion on-line shopping mall from the panel of an online survey agency(www.inr.co.kr) and 1049 responses were analyzed. For analysis of data, descriptive analysis, Cronbach's ${\alpha}$, $\chi$$^2$-test, one-wav ANOVA, Ducan test and stepwise regression analysis were applied. The results of this study were as follows: Firstly as a result of differences of purchasing experience and future purchasing intention via internet, 4 consumer groups were generated: internet patronizing group, trial and unsatisfied experience group, future purchasing intention group, and internet carelessness group. Secondly each group differences was found in demographic variables such as age, marital status, income and employment status. Croup differences were also found in personal, product, and store variables except tangibility. According to consumer groups, different factors were directly impact on consumer satisfaction.

This paper aims to discuss the concept of resilience in floating housing, to investigate the resilient features of floating houses & to review the possibility of floating housing as a new form of resilient living, and to suggest some reference ideas for the planning and design of floating housing projects. Resilient features of the floating house can be summarized as the buoyant characteristics for natural disasters, the easy employment & potential use of renewable and nearly self-sufficient energy systems in locations subject to limited energy sources, the movability, mobility, long life, water recycle system, prefabrication and modular construction with the potential for reduced environmental impact. Additional benefits include the potential for a peaceful and comfortable atmosphere due to direct connections with nature, good relationship with neighbors, a solid social spirit of unity, and sense of security. Considering the resilient features of floating house at a time of serious climate change requires a new paradigm, and floating/amphibious/floatable housing has great possibility as a new form of resilient living.

The securing of raw material is an important requirement for economic development. Many countries, including Korea, actively seek out a stable supply of minerals such as manganese. Manganese nodules are rock concretions on the sea bottom formed of concentric layers of iron and manganese hydroxides around a core and include several strategic minerals necessary for economic development. In particular, the manganese nodule development project (MNDP) plays an important role in the Korean national economy. This study attempts to apply input-output (I-O) analysis in investigating the economic impacts of the MNDP in the Korean national economy. A static I-O framework was employed, focusing on four topics in its application; the production-inducing impacts, the value-added-inducing impacts, the employment-inducing impacts and R&D-inducing impacts of MNDP investments on other sectors. To this end, several versions of the demand-driven models are utilized. In addition, inter-industry linkage analysis is performed to obtain information on the forward and backward linkage effects of industries, including MNDP, to quantify the strength of causation among these industries.

Nowadays, circulation industry is taking charge of important role in improvement of competitive power on the manufacturing industry and public welfare increase of consumer, price stabilization, employment creation and so on. A lot of research have been progressing for formation of total circulation complex, but decision making for selection of location on some facility is only calculated the optimum value when correct data values are inserted. However, a lot of decision making is accomplished in situation that have little knowledge of objective and constraints and as real world is also evaluated inclusive of analyst's subjectivity about variable, indefinite and fuzzy part, so it is decreasing a reliability on evaluation result and complicating objective evaluation on various effect and negative impact. Accordingly, from under like this situation, this study is to develop location decision model of circulation complex using fuzzy theory from the intention for the most reasonable decision making in fuzzy situation based on decision making problem on conventional location and size decision that did to be satisfactory constraints necessarily.

Purpose: The study was to determine variables related to the depressive impact of emotional labor among workers. Method: 443 respondents were surveyed through the NIOSH generic job stress questionnaire from December 1st through December 30th, 1999. Results: 1. Employment type and job insecurity showed a significant relationship with developing depression, load and role ambiguity. 5. Intervention programs and effective communication networks are needed to help workers cope with their job stress in a positive manner. Conclusions: First, given the correlation between the frequency of avoiding tactics and depression levels, an intervention program is needed to help workers cope with their job stress in a positive manner, Lastly, because role ambiguity was one of the main causes of depression among workers who perform emotional labor, establishing an effective communication network is important to make communication flow within the workplace clear and open.
