One of the fastest-growing job categories for women in both the developed and the developing nations of the world is that of self-employment. In 1990 women accounted for 29% of all self employed workers. In Korea, self-employed women including unpaid family workers accounted for 40.4% of all female workers. They are in economically low status and have heavy workload. So, this study examines the real state and problems of self-employed woman. For this purpose, the transition of the number of self-employed women is nationally compared. And the statistical data and time use data on them and role conflict due to paid work and household work are presented. In the future society, self-employment will be a good alternative to self-realization and career for women. So, for self-employed women, following education is needed according to stages of business and characteristics of managers; entrepreneurship, management, and balance of work and family.

The use of new words, numerous spoken languages, and abbreviations on the Internet is extensive. As such, automatically acquiring words for the purpose of analyzing Internet content is very difficult. In a previous study, we proposed a method for Japanese word segmentation using character N-grams. The previously proposed method is based on a simple state-transition model that is established under the assumption that the input document is described based on four states (denoted as A, B, C, and D) specified beforehand: state A represents words (nouns, verbs, etc.); state B represents statement separators (punctuation marks, conjunctions, etc.); state C represents postpositions (namely, words that follow nouns); and state D represents prepositions (namely, words that precede nouns). According to this state-transition model, based on the states applied to each pseudo-word, we search the document from beginning to end for an accessible pattern. In other words, the process of this transition detects some words during the search. In the present paper, we perform experiments based on the proposed word acquisition algorithm using Japanese and Chinese newspaper articles. These articles were obtained from Japan's Kyoto University and the Chinese People's Daily. The proposed method does not depend on the language structure. If text documents are expressed in Unicode the proposed method can, using the same algorithm, obtain words in Japanese and Chinese, which do not contain spaces between words. Hence, we demonstrate that the proposed method is language independent.

PURPOSES : In this research, an SB3-level roadside barrier for a highway transition zone that meets the newly established guide Installation and Management Guide for Roadside Safety Appurtenance is developed. Its performance is evaluated by a numerical simulation and real-scale vehicle impact test. METHODS : The commercial explicit dynamic software LS-DYNA is utilized for impact simulation. An FE model of a passenger vehicle developed and released by the National Crash Analysis Center (NCAC) at George Washington University and a heavy goods vehicle (HGV) model developed by the TC226/CM-E Work Group are utilized for impact simulation. The original vehicle models were modified to reflect the conditions of test vehicles. The impact positions of the passenger vehicle and truck to the transition guardrail were set as 1/2 and 3/4 of the transition region, respectively, according to the guide. RESULTS : Based on the numerical simulation results of the existing transition barrier, a new structural system with improved performance was suggested. According to the result of a numerical simulation of the suggested structural system, two sets of transition barriers were manufactured and installed for real-scale vehicle impact tests. The tests were performed at a test field for roadside safety hardware of the Korea Highway Corporation Research Institute. CONCLUSIONS : The results of both the real-vehicle impact tests and numerical simulations of the developed transition barrier satisfied the performance criteria, and the results of numerical simulation showed good correlation with the test results.

화석연료의 고갈과 국제 유가의 폭등, 기후온난화와 빈번한 환경 재난은 자원 및 환경 담론과 정책의 강화를 요청했으며, 이에 따라 지속가능한 발전의 개념이나 탄소 규제 전략에 바탕을 둔 정책들이 추진되어 왔다. 그러나 이러한 기존 개념이나 전략들은 신자유주의화 과정에 포섭되면서, 실효성이 있는 성과를 얻지 못했다. 이러한 점에서 새로운 전략적 규범적 개념으로 에너지 전환과 더불어 에너지 자립의 개념이 제시된다. 대구시는 비교적 일찍 에너지 문제에 관심을 가지고 솔라시티 정책을 추진해 왔지만, 거시적 배경에 편승하여 도시 에너지 문제를 제대로 대응하지 못했다. 이러한 점에서 이 논문은 대구시의 에너지 문제 실태와 정책의 의의와 한계를 살펴보고, 도시 에너지 전환과 자립을 위한 4가지 원칙, 즉 화석에너지 및 핵에너지에서 재생가능 에너지로의 전환, 공급주도형에서 수요관리 중심 정책으로의 전환, 중앙집중형에서 지역분산형 에너지 시스템으로의 전환, 그리고 시장의존적 관리에서 시민 참여적 에너지 거버넌스로의 전환 등을 제안하면서 이에 바탕을 둔 구체적 방안들을 제시하고 있다.

Todays, there is fast transition about the new manufacturing IT methodologies from the conceptual phase into the practical application phase for the strengthening of enterprise competitiveness in manufacturing industry. One of those new methodologies is PLM (Product Life-cycle Management). PLM methodology consists of 3D CAD for the product design, PDM (Product Data Management) for the data management based on the collaboration platform and lastly DM (Digital Manufacturing). DM has evoluted from the stand-alone computer simulation of early 1980s, and now it covers the overall production development and production. Unfortunately, there exist serious critical problems about the actual application of DM for the real work. This is owing to the transition of the point of view from stand-alone type application (such as flow simulation or robot simulation) to that of business process about product development and production management. In this paper, we propose an application framework for the successful project with the digital manufacturing methodology with the concept of Information Strategy Planning, which enables the systematic diagnosis and the quantitative evaluation. Also, we introduce the actual practice of the proposing framework with the ISP project for 'Analysis & Simulation Technique of manufacturing process project' that is being conducted by Chungnam Techno Park.

A typical small firm in consumer goods sectors of developing countries is an OEM supplier to big MNCs. Lacking design and marketing capability, a small firm relies on the MNCs for survival but their long term growth is not guaranteed as the MNCs are always looking for, and ready to relocate to, cheaper production sites. In this light, we can say that there is something like "OEM trap" from which most firms from LDCs find difficult to move out (Lee 2005). In this situation, one way for long term growth and catch-up is to make a transition to the OBM (own brand manufacturer). But, the transition is not easy or even risky. This paper analyzes the cases of three companies in Korea to find out common features in their successful transition to OBM. They are Aurora World (a flush toy maker), Hankook Chinaware (a chinaware maker), and Hanacobi (a plastic-made food container maker with the Lock-and-Lock brand). These firms can be commonly characterized by 1) arranging access to external knowledge base and steady increase of in-house R&D efforts and capabilities leading to acquisition of formal IPRs and their management, and 2) establishment of global production networks with factories in lower-income countries as well as their own independent global marketing network.

The study aims to investigate the impact of ownership structure on corporate voluntary disclosure in the listed companies of Bangladesh. While many studies on the impact of ownership structure on voluntary disclosure have looked at developed and developing countries, few studies have been carried out in a transition economy. Using a three-step relative voluntary disclosure index, the study applies a multivariate analysis on the cross-sectional data for the year 2018. The findings indicate that the quality of voluntary disclosure in transition economy is still below average but has improved compared to findings from the previous literature. We found a significant inverse relationship between corporate voluntary disclosure and public ownership, while no significant relationships between voluntary disclosure and institutional ownership, director ownership, and foreign ownership have been found. The empirical findings of the study will provide evidence to promote the voluntary disclosure characterized by the ownership structures. The findings have important implications for both local and foreign investors as they make their investment decisions especially related to a transition economy. Besides, the findings will assist, not only the corporate executives in rearranging their reporting paradigm, but also the regulators and governments in similar transition economy in adopting and formulating their corporate policies and strategies.

Ever since the foundation of the Korean Society for Preventive Medicine in 1947, members of the Society had made remarkable contributions to the public health development and national health promotion. They had played key roles in establishing national health system, improving environmental hygiene, controlling infectious and chronic diseases, promoting family planning, improving industrial and environmental health, and developing health service management. However, the Society had less actively responded to the changes in health service needs of the population that were caused by a rapid epidemiologic transition in last a few decades. Early detection and treatment of chronic diseases including cancer and cardiovascular diseases and risk reduction by the life style modification are major approaches to the contemporary national health problems and they are the core contents of preventive medicine. The author proposed to develop the clinical preventive medicine specialist who will have additional training in clinical medicine for health screening and life style modification to the current preventive medicine training program and thus will be able to provide comprehensive preventive medical services. Another area that the Society may take the initiative is training preventive medicine specialist in the disaster, including bioterrorism, preparedness and management. The Society should be more active in proposing health policy and health service program and also participate collectively in a large scale health research project of the government. These approaches may not only contribute more effectively to the national health promotion but also improve the identity of the Society.
