최근 휴대전화의 보급률이 증가하고, 많은 기능이 집약되면서 휴대전화 인터페이스는 HCI 분야에서 중요한 이슈가 되고 있다. 본 논문에서는 사용자 행위 모델링 기법인 GOMS를 사용하여 휴대전화의 계층 메뉴 구조를 분석하고 사용 시간을 예측하는 개선된 모델을 제시한다. 기존 연구에서는 계층메뉴 구조 내의 모든 작업을 숙련된 작업으로 가정하여 사용 시간 예측모델을 구성하였다. 하지만 실제로 휴대전화의 계층 메뉴 구조 내에는 사용자에게 숙련이 되는 작업과 숙련되지 않는 작업이 섞여 있기 때문에 모든 작업을 숙련된 작업으로 가정할 경우 정확한 사용 시간의 예측을 기대하기 힘들다. 본 논문에서는 계측 메뉴 구조의 정확한 사용시간 예측을 위해, 계층메뉴 상의 작업을 숙련된 작업과 숙련되지 않은 작업으로 분리하여 별도로 사용시간을 예측할 수 있는 방법을 제시한다. 이를 위하여 사용시간 예측모델에 필요한 정신적 준비시간(Mental Operator)의 종류를 제시하였으며 실험을 통해 이를 검증하였다.

Since Korea experienced a 'jobless growth' in 2003, creating jobs in the service sector has been considered as a top priority employment agenda. However, despite high employment outcomes in services, labor productivity remains stagnant in the service sector in recent years. A great deal of concern has been raised regarding newly created service jobs. Critics say low productivity in the service sector will harm the engine of economic growth in our country. This paper investigates the side of the demand for quality of labor, namely, the demand for skills as one of the main source of low productivity in the service sector. To analyze the changes of skills demand, this paper suggests the concept of job-based skills instead of worker-based skills and presents the way of constructing measures of job-based skills. By means of common factor analysis using job information in the Korean Dictionary of Occupational Titles, I extract 4 direct measures of job-based skills, such as cognitive skills, physical skills, fine skills, interactive skills. These skill measures are used to explore and to test how the skill structure changed in the service sector during 2002-2006. Empirical Results show that whereas the goods sector makes progress toward upskilling being represented by increased cognitive elements and softenization of tasks, the service sector, although high-educated workers increased, exhibits trends of deskilling in the sense of job-based skills during 2002-2006 in Korea. The trend of deskilling however does not seem a general aspect in the overall service sector. Rather, it seems a compound process that high-skilled jobs are created, but, on the other hand low-skilled jobs requiring physical labor are produced at the same time.

This article is concerned with exploring labour market transformation in newspaper industry and thereby looking into skill formation and professionalization of journalists. In Korea, according to previous research, newspaper journalist labour market had been characterized by a low inter-firm mobility of workers and patterns of long-term employment and firm-based skill training. However, over the past few years, as new product strategies of newspaper firms has changed due to management crisis employers pull back from the responsibilities of investment on skill training and securing job stability for journalists. However, in spite of overall weakened firm-based skill formation systems within the market, there still seems to be long way to build alternative systems of skill developments for them. As a result, it will be argued that, in the absence of manifest labor market institutions such as apprenticeships or skill certification system, which are assumed to traditionally certify workers' professionalization, occupational identity and professionality of newspaper journalist labour market will be weakened. Labor market data from interviews with journalists in the newspaper industry are used in order to test this hypothesis.

Recent migration is led by skilled labor, This paper performes a cross-country analysis to find the determinants of skilled migration using recently released Doquier and Marfouk(2005) data as dependent variable and economic indicators of nations as independent variables. Regression results show that the skilled migration to OECD countries are driven not only by income motive but also by structural factors, such as industrial structure and life expectancy, which have broader meanings in development. It is noteworthy that structural factors of a nation become more important as its income level rises. English seems to have positive effect on skilled migration. Some region-specific factors, proximity to USA of Caribbean countries and political instability of Gold Coast countreis, for example, are found. Middle-income countries seem to be the most vulnerable to the possible risk of brain drain.

탄소배출에 대한 글로벌 규제 확대는 새로운 산업규제와 무역장벽을 가져오고 있으며, 세계 각국은 재생에너지 개발, 에너지 효율 증대, 환경 개선 등을 동시에 추구하는 녹색투자를 통해 경기부양을 도모하고 있다. 한국 정부는 이러한 환경변화 속에 녹색투자를 통한 새로운 성장기회를 모색하고 있으며, 기업은 저탄소 친환경구조로의 전환을 생존의 문제로 직면하게 되었다. 이는 산업구조의 변화와 전환을 가져올 뿐만 아니라, 인력 구성의 변화와 요구숙련의 변화를 요구한다. 이러한 녹색경제로의 전환에서, 미래 숙련수요에 대응한 인력양성은 녹색경제의 전환에 대한 대응으로서 뿐만 아니라 녹색성장을 견인하는 추동력이 된다. 본 연구는 자동차산업을 중심으로 미래 숙련 수요에 따른 인력양성 방안을 모색한다. 그린카 관련한 미래 숙련 수요에 대해 현 대학교과상의 문제점을 살펴보며 이에 대한 개선방안을 모색하기로 한다. 이를 통해 녹색성장에서 그린카 이외의 타 부문에서의 미래 숙련 수요에 대응한 인력양성 방안을 마련하는 방법론의 개선을 도모한다.

It is expected that labor mobility and inter-industry labor turnover would rise due to the rapid changes in the industrial structure and legal institutions of layoffs after the 1997 economic crisis in Korea. One aspect of economic costs of labor mobility is demise of accumulated skills of workers. Workers' skills could be decomposed into three parts, general skills, firm-specific skills, and industry-specific skills. Using data from the panal data of Korea Labor Institute(KLIPS), I show that the net return to seniority is markedly reduced once industry-experience are controlled for. The returns to industry-specific experience are relatively high. Particularly, the experience in one-digit industry is more important for the white-collar workers, while the experience in three-digit industry is also important for the blue-collar workers. Therefore, it seems that the economic cost of labor mobility would be diverse between the skills and between the working classes.

Global expansion of regulation for carbon emission has brought new industrial regulations and trade barriers while the global economy is promoting economic stimulus through a variety of green investments such as renewable energy development, energy efficiency increase, and environmental improvement simultaneously. Korean government is trying to seek a new opportunity to grow through green investment in this change of business environment and businesses are facing the transition to low-carbon and eco-friendly structure for their survival. It is promoting not only industry structure changes and conversion but also demanding changes of workforce composition and requirement skills. In response to convergence of green economy, manpower development for future skills needs is provided the main impetus for response as well as promotion green growth. This study will analyze human resource development plan due to future skills needs emphasizing on automative industry. Also the study will be researched on the problems of present curriculum of undergraduate and look for improvements tasks. Upon the result, promotion plans for human resource development in other sectors of green car in response to future skills needs in green growth can be found.

This paper first constructs an occupation code-skill match for the Korean labor market by following Autor-Dorn classification on the tasks framework. Over the last 34 years, middle-skill jobs have vanished enormously, while high-skill and low-skill jobs have both increased. Also, jobs have polarized more rapidly in recessions and changed uniquely by pushing old workers into middle and low-skilled jobs and the inter-sector reallocation of workers. Furthermore, jobless recoveries in the recent business cycle could have been alleviated considerably if job polarization had been mitigated.

The purpose of this study is to explore the standards and directions of professional competency and proficiency of social workers in Korea through a review of British cases. In particular, in the face of a super-aged society, this study aimed to improve the proficiency of social workers in the field of elderly welfare in Korea by examining the complacency and proficiency standards of the British Association of Social Workers and the Health Care Professionals Council related to the care of the elderly. With the structure of a Professional Capabilities Framework, the UK promotes the acquisition of competency-based qualifications by specifically presenting the competency of social workers at each stage of qualification. In addition, general and detailed standards of proficiency of social workers in the care field are presented at each qualification stage. In order to improve the competence and proficiency of Korean social workers through a case study in the UK, this study presented the need for a standard that connects "common competencies, professional competencies, and proficiency of social welfare professionals." This study also suggested the necessity of the role of Social Welfare Education Association and Association of Social Workers for this purpose
