중소기업의 경우 자본부족과 전문인력 부족의 문제로 획기적인 혁신을 추진하기 어렵다. 따라서 전문인력에 의존하는 급진적 혁신이나 획기적 혁신보다는 담당업무의 개선이나 비용절감을 추구하는 점진적 혁신행동을 추구하는 것이 바람직하다. 이러한 혁신행동은 종업원의 업무에 대해 적극적 관심과 개선을 위한 자발적 노력이 없으면 이루어지기 어렵다. 따라서 종업원들의 임파워먼트는 혁신행동을 촉진하는 동력이 될 수 있다. 또한 혁신행동과 같은 적극적 행동은 조직이나 직무에 대한 심리적 주인의식이 있을 때 더욱 적극적일 것이다. 이에 본 연구에서는 임파워먼트와 혁신행동의 관계와 그러한 관계에서 심리적 주인의식의 조절효과를 실증분석하고자 하였다. 실증분석을 위한 자료수집은 강원 영서지역에 입지한 중소제조업체 종사자 315명으로부터 회수한 설문을 이용하였다. 임파워먼트가 혁신행동에 미치는 효과 및 조직에 대한 심리적 주인의식과 직무에 대한 심리적 주인의식의 조절효과를 분석한 결과, 임파워먼트의 구성요소인 의미감, 자율성, 자기효능감, 영향력은 모두 구성원의 혁신행동에 긍정적 영향을 미치는 것으로 나타났다. 그리고 임파워먼트(의미감, 자율성, 자기효능감, 영향력)와 혁신행동(아이디어개발, 아이디어실행)의 관계에서 심리적 주인의식(조직에 대한 심리적 주인의식, 직무에 대한 심리적 주인의식)의 조절효과에 대한 분석결과 의미감이 아이디어개발과 실행 에 미치는 긍정적 효과는 직무에 대한 심리적 주인의식이 높을수록 강하게 나타났다. 그리고 영향력과 아이디어실행의 긍정적 관계도 더욱 강하게 나타났다. 따라서 종업원들의 아이디어개발이나 실행과 같은 혁신행동을 제고함에는 의미감, 자율성, 자기효능감, 영향력과 같은 임파워먼트를 인지시키는 것이 효과적이며, 특히 직무에 대한 심리적 주인의식을 고취시키는 것이 바람직하다고 볼 수 있다. 이를 위해서 경영자의 변혁적 리더십을 통하여 종업원의 자기효능감을 제고하고, 직무에 정체성, 중요성, 자율성, 다양성 등을 부여하는 직무재설계를 통한 영향력이나 과업의미감 제고가 바람직할 것이다.

The lynx spiders are free wandering spiders with long spines on their legs. They do not build web, but hunt small insects on plants. In spite of the facts that the wandering spiders do not produce webs for prey-catching, they also have silk apparatuses even though the functions are not fully defined. This paper describes the microstructural organization of the silk-spinning nozzles and its silk glands of the lynx spider, Oxyopes licenti, revealed by the field emission scanning electron microscope (FESEM). The silkspinning nozzles of this spider were identified as three groups: ampullate, pyriform and aciniform glands. Each group of silk gland feed silk into one of the three pairs of spinnerets. Two pairs of major ampullate glands send secretory ductules to the anterior spinnerets, and another two pair of minor ampullate glands supply the middle spinnerets. In addition, the pyriform glands feed silk into the anterior spinnerets (25-30 pairs in females and 24-40 pairs in males), and the aciniform glands send ductules to the middle (9-12 pairs in females and 7-11 pairs in males) and the posterior spinnerets (16-20 pairs in females and 16-17 pairs in males). Among these, the ampullate one is the most predominate gland in both sexes. However the flagelliform and the aggregate glands which had the functions of cocoon production or adhesive thread production in other webbuilding spiders were not observed at both sexes of this spider.

Recently in Korean Society, risk and safety has become a central discourse in not only the social and natural science but also political decision making. The efficient organizational management contributes to controlling the risk factors in the workplace. For the management is influenced and improved by the organizational culture, the alternatives more than simply improving the work environment or enforcing the education of safety on each workers are required. This study was the status of safety culture in organizational members(managers and workers, and specialist) including the attitude on the safety atmosphere and risk perception, and experiences, knowledges, motivation etc. For this part, the method of questionnaire and statistical analysis are mobilized. The degree of safety commitment of organization members appears relatively high (3.97 in five scale estimation), but there are variations in this results according to socio-demographic characteristics. At the same time, managers and professionals actively participation in the program related to safety than workers in production/sales. The higher income level and career is the more attention to the safety is. Based on this survey, we make an rough suggestion of several tasks to the policy -makers: improvement of communication on the risk and safety is required and in particular, the workers in the relatively low level in production/sales. The education system about safety which is, with one-side, provided by government or managers turns out to be inefficient. Rather, small group performance of the organizational members which they participate in the communication with interaction in the various discourse are able to provoke the safety mood in workplace.

ICLL 66 is the most widely ratified instrument of the IMO and is, along with the International Convention on Safety of life at Sea (SOLAS), the primary document setting forth internationally agreed ship safety standards. ICLL 66 set freeboard requirement based on experience gained from the first Load Line Convention in 1930 and on contemporary developments in ship design. Reexamination of ICLL 66 is indicated by the proliferation of novel ship designs for which it lacks adequate regulations and by significant advancements in analytical seakeeping and deck wetness prediction techniques now available to the designer. In this paper, the Freeboard Advisory Group reviews these issues against the changing climate of the marine industry and maritime administrations, discusses the state of the art in analytical seakeeping programs, and outlines a series of recommendations for the establishment of a new international load line convention for the next century. The steps needs for an international program at IMO are discussed and a new convention is proposed.

The network topology for a wide area sensor network has to support connectivity and a prolonged lifetime for the many applications used within it. The concepts of structure and group in sociology are similar to the concept of cluster in wireless sensor networks. The clustering method is one of the preferred ways to produce a topology for reduced electrical energy consumption. We herein propose a cluster topology method based on sociological structures and concepts. The proposed sociological clustering topology (SOCT) is a method that forms a network in two phases. The first phase, which from a sociological perspective is similar to forming a state within a nation, involves using nodes with large transmission capacity to set up the global area for the cluster. The second phase, which is similar to forming a city inside the state, involves using nodes with small transmission capacity to create regional clusters inside the global cluster to provide connectivity within the network. The experimental results show that the proposed method outperforms other methods in terms of energy efficiency and network lifetime.

This paper identifies the mechanisms governing the industrial location changes in Korea by focusing upon the emergence of the country's large conglomerate business organizations (chaebols). As the country has distinctive industrial organization, production systems, and government-business relations, this study tries to develop an ideal conceptual framework for the analysis of industrial location changes in Korea. It perceives the Korean economy as a system within which 'space-organizing', lage business organizations interact over time with government, smaller firms and multinational corporations at different geographical scales. The usefulness of the model is assessed using a case study of Korea's most representative chaebol, the Samsung Group. This study identifies chaebols as the dominant institutions in Korean society. Their growth and business strategies have been influenced by the Korean Government through its power to allocate capital resources. Regional dynamics of industry and labor, therfore, have been strongly influenced by changes in the location, industrial structure, and production system of chaebols. With econmic power concentrated within a few giant business groups and their major areas of operation restricted, unbalanced regional development has resulted. Dissatisfaction from residents in less-developed areas has pressured the Government to advise chaebols to disperse their production facilities. Most small and medium-sized firms are closely linked to large corporations through subcontracting. By forming hierarchical subcontracting. By forming hierarchical subcontracting systems, chaebols have indirectly exploited scattered, part-time, home-based, female and lower-paid laborers organized by subcontractors. Further, chaebols have expanded their business arena to encompass overseas locations in a bid to overcome the problem of a small domestic market, trade regulations and increased market, trade regulations and increased labor costs. Through their international business networks Korea's local and regional economies are integrated into the world economy. Indeed, the identification of the changing relationships of chaebols with both the Korean Government and smaller firms is the key to explaining the nations's spatial dyanmics of industry and labor.

Inhaled inorganic dusts such as coal can cause inflammation and fibrosis in the lung called pneumoconiosis. Chronic inflammatory process in the lung is associated with various cytokines and reactive oxygen species (ROS) formation. Expression of some cytokines mediates inflammation and leads to tissue damage or fibrosis. The aim of the present study was to compare the levels of blood cytokines interleukin (IL)-$1\beta$, IL-6, IL-8, tumor necrosis factor (TNF)-$\alpha$ and monocyte chemoatlractant protein (MCP)-1 among 124 subjects (control 38 and pneumoconiosis patient 86) with category of chest x-ray according to International Labor Organization (ILO) classification. The levels of serum IL-8 (p= 0.003), TNF-$\alpha$ (p=0.026), and MCP-1 (p=0.010) of pneumoconiosis patients were higher than those of subjects with the control. The level of serum IL-8 in the severe group with the small opacity (ILO category II or III) was higher than that of the control (p=0.035). There was significant correlation between the profusion of radiological findings with small opacity and serum levels of IL-$1\beta$(rho=0.218, p<0.05), IL-8 (rho=0.224, p<0.05), TNF-$\alpha$ (rho=0.306, p<0.01), and MCP-1 (rho=0.213, p<0.01). The serum levels of IL-6 and IL-8, however, did not show significant difference between pneumoconiosis patients and the control. There was no significant correlation between serum levels of measured cytokines and other associated variables such as lung function, age, BMI, and exposure period of dusts. Future studies will be required to investigate the cytokine profile that is present in pneumoconiosis patient using lung specific specimens such as bronchoalveolar lavage fluid (BALF), exhaled breath condensate, and lung tissue.

경부선 철도는 韓半島의 從貫鐵道로 1905년에 일본에 의하여 건설되었다. 일본은 경부선 노선을 당시에 우리 나라에 존재하였던 여러 교통로를 組合하여, 이 철도 하나로 한 반도 전체를 통제할 수 있도록 선정하였다. 따라서, 이 노선은 당시 한국의 주요 水運, 道路 交通, 市場地域 등이 횡단되도록 하였다. 또한, 鐵道驛은 기존의 취락에서 1km이상 떨어져 광범위한 부지상에 입지시켰다. 이와 같이 건설된 경부선 철도는 개통후 30년후에 한국의 空間組織을 크게 변화시켰다. 경부선 철도상의 주요 지점이 급성장하고 개통 전의 여러 상 업, 행정, 교통요지들이 쇠퇴하였다. 또한, 경부선 철도중심으로 모든 기능들이 집중되어 地 域經濟의 兩極化 現象이 나타나기 시작했고, 생태적 不均衡이 누적되어 왔다.
