Healthy Japan 21의 목적은 삶의 질을 향상시킴은 물론 노동가능 인구집단의 유병률을 줄이고 건강수명을 연장시키기 위하여, 21세기 모든 일본인들이 더욱 건강하고 행복한 삶을 향유할 수 있도록 국가사업을 활성화하는 것이다. 구체적 목적은 조기사망을 예방하고 건강생활을 향상하는 것으로, Healthy Japan 21의 전략적 기획과정에서 건강수명의 연장을 실현하기 위하여 2010년까지 달성되어야 하는 구체적인 목적들이 또한 제시되었다. 조기사망을 감소시키기 위하여 사고, 암, 자살, 심장병 감소의 중요성을 인식하고 9개의 주요 목표로 영양, 신체활동, 휴식과 이완, 금연, 절주, 구강보건, 당뇨병 예방, 심혈관계질환 예방, 암 예방을 설정하였다. 흡연, 알콜, 식사 그리고 운동과 같은 생활양식은 스트레스, 비만, 고혈압과 같은 위험요인 및 질병관리와 관련이 있으며, 위험요인은 암, 심장병, 구강질환의 발생과 밀접한 관련을 갖는다. 따라서 질병의 발생을 예방하기 위해서는 건강증진과 일차예방이 강조되어야 한다. 일차예방에 중점을 두기 위해서 우리는 전통적인 질병관리의 중점사항인 정기적인 건강검진을 통해 질병 조기발견을 노력을 게을리 하지 말아야 할 것이다. 아울러 의료비 감소, 병상에 있는 사람들의 감소, 사회세의 감소도 또한 달성되어야 하는 사업의 결과로 설정되어 있다. 가장 최근의 Healthy Japan 2000(1998-99)의 평가에 따르면 목표들의 15%가 달성되었거나 초과 달성된 것으로 나타났다. 이 중 아동과 청소년의 사망률의 경우, 1-14세 아동의 사망률은 1987년부터 26%가 감소되어 2000년도 목표인 인구 100,000명단 28명의 사망을 초과 달성한 것으로 평가되었다. Healthy Japan 21의 두 가지 주요 전략은 일반 인구집단을 위한 전략과 고위험 집단을 대상으로 하는 전략으로 구성된다. 개인의 건강한 생활양식으로의 변화를 포함한 우리의 건강증진 노력은 사람 중심으로 개인의 선택을 기반으로 하고 있다. 이러한 노력을 지원하기 위하여, 각 개인이 정보를 갖은 상태에서 올바른 선택을 할 수 있도록 적당량의 올바른 정보를 제공하는 것이 필수적이다. 이와 같은 일본의 건강증진계획은 2000년 3월에 Healthy Japan 21이 설립되었으며, 2000-2002년 사이 모든 현이 자신의 사업계획을 설정하였으며, 2001-2005년에는 약 반수 정도의 지방자치단체들이 자신들의 사업계획을 확정하였다. 건강증진을 이루는 중요한 수단은 파트너 쉽에 있다. 정부조직 뿐 아니라 건강보험회사, 보건의료서비스 제공자, 교육단체, 대중매체, 사기업, 봉사단체 등을 포함한 건강분야의 조직들은 자신들의 전문적 기술들을 한데 모아 서로 협력하여야 한다. 또 하나의 중요한 수단은 건강 지지적인 환경이다. 개인의 건강증진 노력을 체계화함으로써 지지적인 환경을 조성할 수 있다. Healthy Japan 21에 대한 평가는 2005년에 중간평가가, 2010에 최종평가가 있을 예정이다. 평가결과들은 이후에 진행될 사업의 향상을 위한 기준으로 활용될 예정이다.

This study is concerned on how much effect to activate private security officers from the attitude of CEO in private security companies. Of course the philosophy of CEO at the work is much important element on the company activity. And in small-medium size private security company the effect of CEO is tremendous because most of decision making comes from CEO and company is operated. The result of the analysis of the survey on the CEO in private security business is as belows. a) Most of them are not satisfied and negative from current situation of private security industry because too many companies are scattered and the expected social understanding is too low even though the company was established by their own decision due to it was fit to their aptitude. b) The job position is estimated not high by socio-economical perspective, which would be improved to get higher because this industry is very future business. c) Most of members of the korea security association are in negative on the policy of the korea security association but to enhance of the activity all the members should be in union. d) Must make and settle down a channel to communicate and cooperate each other between public and private sector of security business.

Greenhouse study was undertaken to find tank-mix feasibility of quinclorac with molinate and propanil, selective post-emergence herbicides in controlling barnyardgrass, for reducing the application rate of quinclorac. Following foliar application in combination of quinclorac at 0.038, 0.075, 0.150, and 0.300kg ai/ha with molinate at 0.190, 0.380, 0.750 and 1.500kg ai/ha, and propanil at 0.263, 0.525, 1.050, and 2.100kg ai/ha at 3.5-leaf stage of barnyardgrass, fresh weight and weeding efficacy and their interaction by Colby's efficacy method were evaluated. Percent inhibition of barnyardgrass growth by quinclorac, molinate and propanil at recommended rate were 78.1, 26.1, and 61.7%, respectively. The dose combination shown above 85% in weeding efficacy were from 0.300kg of quinclorac with 0.75kg of molinate and 0.150kg of quinclorac with all rates of propanil. Therefore, combination of quinclorac with molinate tended to additive interaction and that of quinclorac with propanil appeared partially synergistic interaction. Conclusively, for reducing the application rate of quinclorac, the combination of quinclorac with propanil was more synergistic than that of quinclorac with molinate.

In bulding Intelligent Agent Societies (IAS), it is very important to design and implement coordination in accordance with the known requirement and anticipated working conditions. Coordination consists of a set of mechanisms necessary for the effective operation of IAS. Currently, there is little theoretical support that could help in this research is to generate an empirically-based solving systems in which all agent share an identical goal structure and fully cooperate. And we developed a simulation model called "P-System" which produces basic data to be used for statistical analysis to generate a theory of coordination. Coordination among agent in the P-System is dependent on 23 control variables calld TEs(tweakable emtities.)And the level of coordination is represennted by an independent variabe called QMC (Quality Measure Coordination) expressed in numerical terms according tn the definiion of this study. Also, we have studied how to select unbiased subset from the huge total experimental space of the P-System and how to decide the scale of the subset.

This paper assesses the role of informal institutions in determining risk preference among smallholders in Tigray, Ethiopia. We use data from a household survey conducted by the Institute of Poverty Alleviation and International Development (IPAID). We find that households which participate in Debo, an informal labor-sharing institution, or have a friend from whom they can receive help are less likely to be risk-averse. However, participation in Iddir, a traditional form of insurance, is not significantly associated with risk preference. Hence, the existence of social institutions that provide assistance and social connections through reciprocity may be affording security against risk beyond that brought by more monetary forms of insurance. Given the importance of risk attitude in mediating the adoption of improved agricultural production, a policy suggestion is to provide selected aid to households which are less risk-averse agricultural investors. Also, Debo as a labor-sharing institution may serve as a nexus for managing aid and knowledge sharing.

This study presents a sensitivity analysis method for stochastic user equilibrium of multi-modal network flows. We consider a multi-modal network consisting of a road network for passenger cars physically separated from a transit network for public transport. We first establish a sensitivity analysis method with respect to arbitrary link parameters and perform a sensitivity analysis with respect to link capacity and transit line frequency as practical link parameters. Next, We establish a sensitivity analysis method and perform the sensitivity analysis with respect to modal split by passenger car and public transit. As with the elasticity of economics, these results can be important information for analyzing changes in travel behavior due to the changes in operation and policy of transportation facilities, as well as for analyzing the effects of these operational changes and policies. These results also can be utilized as a tool to constitute a multi-modal network design problem by using cooperative game theory.

Relay systems have recently gained attentions because of its capability of cell coverage extension and the power gain as the one of key technologies for 5G. Relays can be exploited for small-cell base stations and the autonomous network, where communication devices communicate with each other cooperatively. Therefore, the relay technology is expected to enable the low power and large capacity communication. In order to maximize the benefits of using a limited number of relays, the efficient relay selection method is required. Especially, when two nodes exchange their data with each other via relay, the relay selection can maximize the average data rate by the spatial location of the relay. For this purpose, the average data rate is analyzed first according to the relay selection. In this paper, we analyzed the average data rate when two nodes exchange their data via dual-hop decode and forward relaying considering the interference by the concurrent transmission under Nakagami-m fading channel. The correctness of the analysis is verified by the Monte Carlo simulation. The results show that the concurrent transmission is superior to the non-concurrent transmission in the high required data rate region rather than in the low required data rate region.

North Korea(NK) has designated the special economic zones(SEZs) since the first one in Rason. But, why have the SEZs in NK still not been developed successfully? This study comparatively evaluated the SEZs in China, Vietnam and NK, with respect to 'context/purpose', 'development/management system', and 'location/infrastructure.' NK's strategies for the SEZs were different from those of China and Vietnam in terms of historical context and development purpose. China and Vietnam chose the market opening policy aiming to reform their national economy, while NK tried the opening policy without the economic reform. This difference made NK's decentralization and location strategies marginal. In spite of the positive land system and tax benefit of NK, the strategies couldn't make a successful result. The implications of this comparative study are as follows. Firstly, NK needs to establish a strategy for the SEZs in accord with the comprehensive and long-term plan for economic development and 'trustworthy and substantial market-systems' being compatible with outside world. For that, NK has to secure the regime stability in political and diplomatic dimensions. Secondly, NK has to carry out policies of decentralization and location of the SEZs more positively. Thirdly, in order to solve the problem related to lack of infrastructure capital, NK needs to utilize a BOT scheme.

새 천년을 맞이하여 국내 이동전화 시장은 규모와 기술적 측면에서 놀랄만한 변화 를 겪게 될 것이다. 음성중심의 2세대 이동전화 서비스는 보급율이 50%를 넘어서며 포화수 준에 근접하고 있으며, 앞으로 무선데이타 통화량이 크게 증가하여 3~4년 후에는 총 통화량 의 50% 이상을 점유할 것으로 예측된다. 통신사업자들은 통신망의 광대역화와 글로벌화, IP Network 화를 더욱 강력하게 추진하고 있으며, 올 연말로 예정된 IMT-2000 사업자 선정은 이러한 추세를 더욱 가속화시킬 것으로 전망된다. 특히, 인터넷과 이동전화의 융화는 인간의 삶과 문화를 한순간에 변모시킬 혁명적 위력을 내포하고 있다. 정보화 시대를 향한 정보통 신업계의 대변혁이 그 절정을 향해 가속도를 붙이기 시작한 것이다. 신세기통신은 이러한 변화와 혼돈의 거친 물결 속에서 21세기 '정보통신 업계의 강자'로 도약하기 위한 힘찬 항해 를 진행하고 있다. 2000년 상반기까지 IS-2000시스템을 구축하여 최대 144kbps 수준의 고속 데이타 서비스를 제공하는 한편 i-TOUCH 017 컨텐츠 (Contents)를 한층 다양화, 첨단화 하는 등 본격적인 이동인터넷 사업을 전개해 나갈 것이다. 또 CDMA 국제 자동로밍 서비스 를 일본, 미국, 유럽 등 전세계로 확대하여 017 서비스의 글로벌화를 이룩할 계획이다. 이러 한 통신망 진화와 이동 인터넷 사업의 상당 부분을 SK텔레콤과 함께 추진하게 될 것이며 이러한 양사간의 전략적 제휴에 따른 시너지 효과는 오는 연말 IMT-2000 사업권의 성공적 확보로 이어질 것으로 기대된다. 21세기 정보통신산업은 광대역 통신망으로 대변되는 하드 웨어와 인터넷 컨텐츠로 대변되는 소프트웨어가 서로 융화되는 방향으로 발전할 것이다. 이에 따라 고객의 서비스 만족도나 사업자 선택 기준은 기존 통화물질 중심에서, 사업자가 제공하는 컨텐츠의 다양성이나 편리성으로 변화하는 것이 국적을 바꾸는 것보다 어려운 시 대가 멀지 않은 미래에 도래할 것이다. 신세기 통신 과 SK 텔레콤에는 현재 1,300만명이 넘 는 고객이 있으며. 이들 고객은 어 이상 음성통화 중심의 이동전화 고객이 아니라 신세기 통신과 SK텔레콤이 함께 구축해 나갈 거대란 무선 네트워크 사회에서 정보화 시대를 살아 갈 회원들이다. '컨텐츠의 시대'가 개막되는 것이며, 신세기통신과 SK텔레콤은 선의의 경쟁 과 협력을 통해 이동인터넷 서비스의 컨텐츠를 개발해 나가게 될 것이다.
