본 연구는 휴양림의 기능 향상을 위한 식생관리 방안을 제시하고자 경기도 남양주시 수동면 외방리 축령산자연휴양림을 대상으로 실시하였다. 휴양림 내 등산로 및 산책로 주변의 주요 분포종인 잣나무 인공식생지와 자연식생지인 낙엽활엽수림의 생물다양성 조사 및 분석 등을 실시하여 휴양림 기능향상을 위해 식생유형별 관리를 위한 관리방안을 도출하였다. 연구방법은 생물다양성 측면에서 식생관리, 현존식생 및 비오톱 현황, 식생유형 구분, 식생구조, 야생조류 서식구조 등의 기능검토를 실시하였다. 휴양림내 식생유형 구분은 현존식생과 비오톱현황을 기초로 잣나무 인공조림지와 자연상태의 낙엽활엽수림으로 크게 구분할 수 있으며, 등산로 및 산책로 주변 대표식생 조림여부, 식생관리 등에 따라 4개의 유형(관리되지 않은 인공 잣나무림, 관리된 인공 잣나무림, 단풍나무 비율이 높은 자연상태의 낙엽활엽수림, 관리된 낙엽활엽수림)으로 구분하였다. 식생구조 분석결과 종다양도는 낙엽활엽수림이 인공 잣나무림 보다 종다양도가 높게 나타났고 관리되지 않은 상태가 관리된 상태보다 종다양도지수가 높게 나타남을 알 수 있었다. 야생조류 서식구조 분석결과 관리된 잣나무림은 층위구조가 빈약한 단층으로 식재되어 다양한 야생조류의 이동통로로서 부적합한 구조이고, 관리되지 않은 자연상태의 낙엽활엽수림, 잣나무림 등이 양호한 야생조류 서식구조를 가지고 있음을 알 수 있었다. 생물다양성 기능 검토에 근거하여 관리유형을 크게 보전관리와 복원관리로 구분할 수 있었다. 보전관리 중 기존낙엽활 엽수림 유지유형은 자연상태의 낙엽활엽수림 지역, 관리된 낙엽활엽수림 지역 등이 속하며 생태적 관리유형은 관리되지 않은 인공 잣나무림 지역을 설정하였고, 복원관리지역인 생태적 복원유형은 관리된 인공 잣나무림 지역으로 설정하여 식생관리 유형별 관리방안을 제시하였다. This study was supposed to offer vegetation plans for functional improvement of the recreational forest by researching Mt. Chukryong which is located at Oebang-li Sudong-Myon Namyangju Kyong-gi Province inKorea. In this study, artificial vegetation and natural vegetation near trails in recreational forest were researched through biodiversity analysis. From this analysis process, a typical management improvement of the biodiversity functions were examined by reviewing functions biotope condition, vegetation structure and wild bird community condition. Typical vegetation system was divided into four detail parts: Managed artificial Pinus koraiensis forest, Not managed artificial Pinus koraiensis forest, Natural deciduous forest and Not managed deciduous forest. As a result of the vegetation structure, the numerical value of the deciduous forest species diversity was higher than that of artificial Pinus koraiensis, and the numerical value of the managed condition was higher than that of not managed condition. As a result of a habitat structure analysis of the wild bird community, managed Pinus koraiensis forests were inadequate structure for wild birds to habit in there because the forests had weak structure layers, but unmanaged deciduous forest and unmanaged Pinus koraiensis that had diverse layers was proper places for birds to in habit. Thus, based on the functional analysis of biodiversity, management patterns of the target area were concluded in two manners: conserving management and restoring management. Deciduous forest protection target areas included natural deciduous forest area and managed deciduous forest area, ecological restoration target area included unmanaged artificial Pinus koraiensis area and restoring management target area includes managed artificial Pinus koraiensis.

콘크리트 구조물은 자연적인 혹은 인위적인 온도의 상승, 강하로 인하여 동결-융해 작용을 받게 되어 구조물의 성능저하를 야기시킨다. 현대에 들어서면서 콘크리트의 내구특성을 파악하기 위한 연구적 요구가 증가되고 있다. 따라서 폐주물사 콘크리트를 실제 구조물에 적용하기 위해서는 내구특성에 대한 연구가 반드시 이루어져야 한다. 폐주물사를 혼입한 콘크리트의 내구특성을 파악하기 위한 동결-융해 실험은 폐주물사의 잔골재 치환율, 물-시멘트비, AE제 사용 여부를 주요 변수로 하여 실시하였다. 원형공시체를 제작하여, 동결-융해 시험기에 넣어 -18∼4℃로 급속 동결-융해를 진행시키면서 매 23싸이클마다 동탄성계수를 측정하였다. 실험결과 AE제를 첨가했을 때 물-시멘트비가 적을수록, 폐주물사의 치환율이 클수록 전반적으로 강도가 증가하는 것으로 나타났으며, 물-시멘트비가 증가함에 따라, AE제를 사용한 콘크리트가 동결-융해 저항성이 증가하는 것으로 나타났다. 특히 폐주물사 치환율이 50%일 때가 동결-융해 저항성이 가장 좋은 것으로 나타났으며 그 다음으로 25, 0% 순으로 저항성이 좋은 것으로 나타났다. 따라서 폐주물사 콘크리트가 내구성이 우수한 것으로 나타나 폐주물사를 콘크리트에 재활용 할 수 있는 것으로 나타났다. Concrete structures has been deteriorated by the freezing and thawing due to temperature gap. This study was conducted to evaluate durability of concrete which are increasingly demanded recently. Therefore the research of durability must be executed for application of waste foundry sand concrete real structures. Concrete durability properties incorporating waste foundry sand was performed with the variable of W/C ratio, Sand/Waste foundry sand ratio and Air entrainment-Non air entrainment. Cylinder specimens were made and subjected to freezing and thawing cycle at -18℃ and 4℃. Dynamic modulus of elasticity were evaluated as F/T cycle increase. The results show that strength of concrete is increased the W/C ratio decrease, the Sand/Waste foundry sand ratio increase when the concrete contains AE agent and decreasing W/C ratio and AE concrete makes improved resistance of freezing and thawing improved. Especially, resistance of freezing and thawing is improved by Fine aggregate/Waste foundry sand ratio which is 50%, 25%, 0% in a row. Therefore it is turn out the waste foundry sand could be applied to concrete from the experiment.

Recently the textile Industry has undergone dramatic changes as a result of technology developments. For successful propulsion of Milan Project as a new paradigm, all of the parties concerned including textile firms, local goverment in Taegu city, research institutions, and universities, must be in harmony with the goals and, strategies of the Milan Project. Firstly, It is necessary for all interested parties to establish the explicit goals of the Milan Project. We should strength textile industry in the Taegu area one of the main industries. Then, we should extend this into the manufacturing of fashion related products. Secondly, we must decide that who will have the responsibility for the Milan Project effectively. We consider the merits and demerits of government authorities in Taegu city, a single corporation and business consortium as a co-ordinator of the Milan Project. We can consider several possibilities. If a corporation takes control of Milan Project, it is easy to cooperate with foreign companies and reflect consumer needs. On the other hand, we can expect several kinds of difficulties like the condition of locations and funds. If a consortium leads the Project, it can get a variety of support and establish networks, as well as secure independence and neutrality. However, when constituting a consortium, it can trigger problems like an balancing the interests of various partners and lack of consortium know-how. However, a business consortium is the best co-ordinator for the Milan Project. Thirdly, regional textile industries must cope a changing environment and be able to set up new strategies. Fourthly, we must research and analyze how can we apply the model of Dong-dae moon market, which is the best fashion and clothing market in Korea. Fifthly, we should prepare the Special Act related to the textile industry, and raise funds. The Milan Project will put into operation from 1999 to 2003. We cannot change the structure of the regional textile industry in 5 years through investments alone. Textile companies must take part in raising funds positively and actively. Finally, the Milan Project is an incomplete project. This unfinished Project should be carried out by all interested parties for a successful strategy, and cooperate with universities, industry and research institutes and the authorities concerned voluntarily. This Project depends on how much the interested parties cooperate. At this time the Milan Project is led by the government, so future Project which will change our textile industry into a new paradigm and a knowledge intensive industry should be led by textile industries. So we prepare for the new paradigm of industry environment, that is knowledge intensive management, for the 21st century.

이태경 울산대학교 2002 조형논총 Vol.5 No.1

특정 상품이 시장에서 타 상품과의 경쟁에서 이기기 위해서는 소비자 기호를 충족시키는 디자인이 중요한 요소이다. 소비자 기호를 분석하기 위해서 사용되는 회귀분석을 하기 위해서는 회귀분석모델을 설정하여야 한다. 회귀분석모델을 설정하기 위해서는 분석자료의 영역에 대한 지식과 회귀분석에 대한 지식이 필요하다. 이는 일반 분석자에게는 제약이 된다. 이 논문에서는 데이터마이닝 기법을 이용하여 회귀분석모델을 쉽게 할 수 있는 방법을 시도한다. A design is a key factor of a product for the product to dominate against other products in a market. A regression methodology is used to analyse a consumer's trend in a market. A analyzer's knowledge of both the domain of a data and the regression methodology itself is the least requirement for a reasonable result of a regression. This may be a burden and sometimes hinder a layman from trying a regression. This paper proposes a method to integrate a dataminng technique into a regression methodology and to use a regression methodology with easy.

해외직접투자에 따른 위험관리에 관한 연구

전경태,김계화 계명대학교 국제학연구소 2001 국제학논총 Vol.6 No.-

해외직접투자에는 반드시 위험이 수반된다, 그래서 해외직접투자 시 위험에 대한 인식과 효과적인 대응책이 요구된다. Ghoshal(1987)가 지적하였듯이 위험을 관리하는 것은 해외직접투자와 같은 국제적으로 운영하는 기업들의 중요한 목적이라고 한다. 해외직접투자기업들은 위험에 대해서 정확하게 인식해야 하며 이에 따른 효과적인 관리가 요구된다. 해외직접투자 따른 위험관리를 위해서 우선 어떠한 형태와 종류의 위험이 존재하는 것을 인식하는 것이 중요하며 특정한 위험만 고려하지 않고 종합적으로 인식하는 것이 중요하다. 위험은 기업의 외부적인 요인과 내부적인 요인으로부터 발생되는데 해외직접투자 위험에 관한 연구들은 특정한 위험에만 치중하고 그와 관련된 다른 위험은 제외시켰다. 그래서 본 연구에서는 위험에 대해서 통합적으로 다루고 효과적인 위험 관리전략을 제시하고자 한다. 본 연구에서는 위험을 세 가지 차원으로 나누어서 연구한다: 일반환경에 기인한 위험, 산업특성에 기이한 위험, 기업특성에 기인한 위험. 일반환경에 기인한 위험은 주로 국가위험이며 국가 위험에는 정치적인 위험, 경제적인 위험, 이전위험, 환위험, 입지 또는 근접의 위험, 주권위험, 상업적인 위험 등이 포함된다. 산업환경에 기인한 위험에는 경쟁위험과 자원위험이 포함되며 기업특성에 기인한 위험에는 계약 위험과 이전, 운영, 소유통제의 위험이 포함된다. 해외직접투자에 따른 위험관리전략은 투자전의 전략과 투자후의 전략, 수용과 몰수후의 전략으로 나누어 볼 수 있는데 투자전의 전략은 양해 각서, 계획매각, 보험 등을 포함하며 투자 결정 이후의 관리 전략에는 생산관리전략, 마케팅전략, 재무관리전략, 조직관리전략, 인사관리전략 등 다섯 가지가 있다. 또한 몰수나 국유화의 조치가 이루어진 후의 전략은 두 가지가 있는데 합리적인 협상, 파원 전략에 따른 협상, 법적 치유의 모색, 경영 포기와 구제 가격만 찾는 결정 등 4 단계로 나누는 전략이 있고 다른 한 가지는 이성적인 교섭단계, 실력행사를 위한 전술전개의 단계, 법적인 구제절차를 밟는 단계, 철수 및 보상청구의 단계 등 4 단계로 나누어진다. 상기의 전략을 종합해서 분석하여 추가적인 방안을 제시한다면 우선 해외직접투자 위험에 대한 이해 및 이용되고 또한 현지에서의 기업형태를 적절하게 선택하는 것이다. 그 다음에는 현지화전략을 추진하는 것이며 현지국에서의 인맥관계의 유지와 지역별, 국별 위험 분산도 상당히 중요하다. Foreign Direct investment Firms (FDIFs) are prone to risks, so the recognition of risks and effective management strategies against risks are useful TO them. Ghoshal(1987) wrote that managing risks are one of the primary objectives of firms operating internationally. FDIFs need to set up risk management strategies. Treatments of risks in FDIFs largely focus on particular risks to the exclusion of other interrelated risks, although these risks are assigned to factors either external or internal. This paper develops a framework for categorizing risks faced by firms operating direct investments in foreign countries, and it outlines corporate risk management responses. This paper divides risks into three levels: general environment, industry and firm-specific variables. General environment risks refer to country risks; these include economic, transfer, exchange rate and location or neighborhood risks; also, sovereign, political and commercial risks. Industry risks include competitive and resource risks. Firm-specific risks involve four divisions: contractual, transfer, ownership and operational risks. Risk management strategies in FDI can be divided into three levels: pre-investment, post-investment and after expropriation and confiscation. Pre-investment strategies include concession agreement, planned divestment, insurance and guarantee. Post-investment strategies involve production and logistics, marketing, financial, organizational and human affairs strategies. After expropriation and confiscation, powerful strategies are used in resonable negotiations, lawsuits, renouncing management and getting relief. As well as the strategies mentioned above, additional ways could be as follows: understanding and using FDI insurance performed by banks, choosing suitable corporate forms in host countries, localizing strategies, maintaining good relationships with THE governments of host countries and dispersing risks by zeros and countries.

This study was conducted to determine the relationship between social support and self-esteem of the psychiatric patients. One hundred ninety subjects( 95 psychiatric patients and 95 normals) between the ages of 18 and 65 were included in the study. The psychiatric patients were recruited from outpatient clinic of C university hospital in Taejon city. The normal subjects were residents of Taejon, who have been matched with the psychiatric patients according to age, sex and spouse status. The instruments used for this study were Norbeck Social Support Questionnaire developed by Norbeck, Lindsey and Carrieri, and Rosenberg's Self-esteem Scale. The collected data were analyzed using percentage, x^2-test, t-test, ANOVA, Pearson Correlation Coefficient by SPSS-X. The results of this study were as follows; 1. The score of psychiatric patients was lower than that of normals on social support(total functional support : t==-8.22, p<.001 ; total social support network : t=-7.82, p<.001). 2. The score of psychiatric patients was lower than that of normals on self-esteem (t = -6.55, p<.001). 3. The relative variables influencing the degree of social support of psychiatric patients were birth order(F=2.66, p<.07), normals were sex(F=4.99, p<.05), birth order(F=4.06, p<.05). 4. The relative variables influencing the degree of self-esteem of psychiatric patients were sex(F=6.21, p<.01), age(F=5.07, p<.008), spouse status(F=7.32, p<.008), birth order(F=3.51, p<.03), normals were sex(F=-9.86, p<.002), age(F-4.4, p<.01) 5. The relationship between the degree of social support and self-esteem of psychiatric patients was found to be a positive correlation that was not statistically significant (r =.054, p>.05). 6. The relationship between the degree of social support and self-esteem of normals was found to be a positive correlation (r=.206, p<.02).
