제4기 만빙기에서 후빙기 사이의 기후변화는 인류문명에 있어 정착생활 및 농경활동과 더불어 잉여생산물 저장을 위한 토기제작 등과 같은 생활상의 변화를 가져 온 계기가 되었다(F.M. Chambers, 1993; Guoyu Ren, 1998; Mori Y, 2002; Martin Bell et al., 2004). 식물화석, 화분, 식물규소체 등의 대리자료(proxy data)를 이용하여 이시기의 식생환경을 밝히는 것은 고생태복원분야 뿐 아니라 당시의 환경변수들 을 추정하여 인간활동에 어떠한 영향을 미쳤는지에 대한 중요한 정보를 제공해준다. 그러나 홀로세 초기 환경은 인간에게 지대한 영향을 미쳤으나 후기로 올수록 인간 스스로가 환경을 변화시키는 주체가 되었다(Martin Bell et al., 2004). Meyer&Turner(1994)는 인간활동이 자연적인 영향보다 생물구에 시계열적인 변화를 가져왔다고 하였으며, R.B Singh(1995)는 현재뿐 아니라 과거까지 다양한 인위 적인 간섭이 전지구적인 환경변화를 야기 시키는 주된 원인이라고 하였다. 따라서 환경을 복원한다는 것은 바로 그 지역을 생활 터전으로 삼았던 당시 선사인들의 생활상을 간접적으로 들여다 볼 수 있는 기회를 제공해준다. 현재까지 국내 고고학 유적지에서 이루어진 대부분의 발굴조사는 유물과 유구를 토대로 당시 선사인의 생활상을 밝히는데 중점을 두었으나 최근 인간과 영향을 주고 받았을 환경에 관심을 갖고 이를 통해 역으로 인간활동을 추적하려는 다수의 연구들이 제4기학, 고고학, 지리학, 인류학, 생물학, 농학, 기후학 등 다양한 분야에서 학제간 연구로 진행되고 있다(황상일 등, 1999; 조현종, 2000; 김주용 등, 2002; 최정민, 2004; 윤순옥 등, 2005). 그러나 이러한 연구에 있어서 어떠한 대리자료(proxy data)를 어떻게 고고학 유적지에 적절하게 적용시킬 것인지 대리자료의 조성변화나 값의 해석에 있어서 기후인자와 인간영향을 어떻게 분리해 낼 것인지에 대한 문제점이 남는다. 예를 들어 화분분석의 경우 1차적인 환경변화에 따른 식생조성변화를 반영한다. 인간이 활발한 농경활동을 하게 되면서 주변식생을 제거하게 되고, 제거된 나대지에는 재배작물과 잡초들이 자라게 된다. 그리고 이들 화분은 주변 소택지에 퇴적물과 함께 퇴적되어 화분분석 결과 벼과(科)(Gramineae)와 문화지표수종이라 부르는 여뀌속(屬)(Persicaria), 국화과(科)(Composite), 쑥속(屬)(Artemisia), 쐐기풀속(屬)(Urtica) 등의 화분에 있어 확연한 조성변화를 보여준다. 그러나 화분을 이용한 분석은 토탄층이나 유기질 퇴적물이라는 한정된 토양에서만 분석이 가능하며, 조성변화에 있어서 역시 기후와 인간활동의 영향 모두를 반영하기 때문에 이를 구분해 주는 명확한 기준이 필요하다. 따라서 본 연구에서는 이러한 다양한 대리자료 중 고고학 유적지에 적용 가능한 동식물 화석 및 미화석, 지리, 지질학적 자료에 어떠한 것들을 적용할 수 있는지를 살피고, 몇 가지 대리자료를 중심으로 선사인의 농경활동에 대해 살펴보고자 한다.

The distribution of cryophilous arctic-alpine and alpine plants in Korea is reviewed in connection with palaeoenvironment, along with a discussion to their origins, patterns of migration, and their refugia. At present, the estimated number of Korean arctic-alpine and alpine species is 419, and this includes 75 arctic-alpine species, 239 alpine species and 105 Korean endemic alpine species. The disjunctive distribution of cryophilous arctic-alpine and alpine plants is likely to be due to first, the downslope and southward expansion of those species towards the Korean peninsula as a primary refugia from the arctic region as the Pleistocene glacial phases approached, and then their subsequent isolation upslope in mountain areas toward a secondary refugia as the interglacial and post-glacial climatic ameliorations followed; secondly, the expansion of forest tree communities on lowland and montane areas subsequent to the end of the Pleistocene has had the effect of dividing formerly high mountains as a result of the increased competition; and thirdly, the general disapperance or restriction of available habitats for arctic-alpine and alpine species because of post-glacial climatic amelioration. The existence of 139 alpine species exclusively in the north of Korea may be due to the following reasons; first, frequent exchanges of alpine floras with other neighbouring East Asian regions would have been facilitated; secondly, there are numerous high mountains available for the alpine plants to survive and prosper during the post-glacial period; thirdly, the existence of easy accesses between mountains within the north, which has enabled alpine floras to migrate when necessary; and finally, the availability of diverse environments and habitats for the alpine flora of the north. However, the continued survival of those species in Korea at the world's or East Asia's southernmost limits of their distribution for many species is in danger if global warming associated with the greenhouse effect takes place.

This thesis is research about the development and application of the panorama image in contemporary artwork, focusing on sculpture and installation. The samples of artworks are a selection of representatives from numerous examples of works that cannot be introduced without exceeding a reasonable scope of the thesis. A brief outline of the historical concepts of the perspective will describe the development of the panorama in itself. Some technical explanations and the practical use of the panorama with its link to 3-dimensional applications should bridge the explanation gap between the 2nd and 3rd dimensional usage of the panorama in contemporary artwork. Furthermore, some philosophical statements are proposed in the discussion. One of the main interests and initial motivation of this study was my personal believe that there is always a relationship between social philosophical values and the way a society sees or encounters visual structures. In other words the contemporary understanding of space and perspective is mirroring the actual zeitgeist and creates an exemplary visual aesthetics.

Gonadal development and reproductive cycle off Gomphina melanaegis collected in the coastal waters of Chumunjin, Korea were investigated monthly from April 1996 to April 1997. G. melanaegis was dioecious, The gonads were located between the digestive diverticula and muscle tissues of the foot, The ovary was composed of a number of ovarian sacs, and the testis was composed of several testicular tubules. The flesh weight rate was reached the maximum in August ($23.0\%$), and then decreased to $19.8\%$ in September. In March, the value was reached the minimum ($17.8\%$) and then increased, The size of mature oocyte was ranged $50\~60\mu$m in diameter and had a germinal vesicle with a nucleolus. Mature oocyte contained a large number of yolk granules and lipid granules in its cytoplasm. The spermatozoon was consisted of a conical nucleus with acrosome, a middle piece containing four mitochondria and proximal and distal centrioles, and a flagellum, Sex ratio (male/female) and minimum size for sexual maturation of G. melanaegis were 0.79 and about 25 mm in shell length, respectively. The reproductive cycle could be classified into five succesive stages: multiplicative (December to March), growing (April and May), mature(June), sprawning (July and August), and degenerative and resting (September to November) stages.

We investigated the effects of salinity on an estuarine cladoceran, Diaphanosoma celebensis as a substitute live food organism of Artemia, which has been used for the next step of rotifer, in the course of seedling production of marine fishes, Culture density for growth, possibility of stable culture (RPGI: Relative Population Growth Index) and food feeding activity (RCN: Remaining Cell Numbers) of D. celebensis were investigated at intervals of 5 ppt under 10 steps of different saline conditions from 0 to 45 ppt. According to the results, the experimental group, which was regarded as the best condition of culture density for growth, stable culture possibility (RPGI) and good food feeding activity (RCN), was salinity culture condition of 20 put, and relative stable culture conditions were observed under saline concentrations $15\~35\;ppt$. Their functions under culture conditions of lower or higher salinities than 20 ppt appeared remarkably to be decreased, while all individuals were dead under the saline condition of 0 ppt after the beginning of the experiment. From these results of this study, it is assumed that estuarine cladoceran, D. celebensis can be cultured easily as a substitute live food organism of Artemia in the course of seedling production of marine fishes.

The relationship between the catch of squid, Todarodes pacificus, according to the jigging depth and underwater illumination by fishing lamps was investigated during nighttime operations off-Tusima Islands in November 1994 and off-Oki Islands in November 1995. We used echo sounder to observe the distribution of squid. Echo images on the echo sounder showed the distribution of squid at the water layer of 50 meter depth at the beginning of jigging operation. After the time elapsed, a continuous dense image had moved to the layer of 60-80 meters jigging depth. A larger number of squid were caught by jigging machines set at a lowest depth of 90 meters, when it compared with machines set at a 60 meters. However, Catch increased around 60 meters jigging depth, when fishing lamps output were switched to 24 kW halogen lights:.The underwater illumination, under the each light power of fishing lamps of squid jigging boat was continuously measured with an underwater illuminometer. Values of the underwater illumination, when schools were distributed from 60 to 80 meters, ranged from $3.0\times10^{-2}lx\;to\;3.4\times10^{-3}lx$ in average at $80\~360$ kW fishing lamps output of squid jigging boat.

Korean movies with a great variety of styles have recently succeeded in drawing people's attention Rule number one is "the more entertainment, the more audiences". On the top of box offices are always the movies that have a number of spectacular scenes, pounding sounds and big budget characters. Hong Sang Su movies, however, receive attention from the public without above noted descriptions. One of his effective methods of expression is "realism" He has illustrated the trivial episodes with his own wits and ways. Not only has his style become famous and popular but he has many followers. He enjoys using ordinary emotion and sentiment that are likely to happen to everyone. This paper uses two tools. One is the traditional analysis of realism. The other is how he can approach the public meaningfully by listing common elements he frequently uses in his movies. Nevertheless, we can't fully understand his realism by explaining how he shows our everyday life and how much his movie looks like it. Though admitting there are so many preceding papers on his works but this paper will try to look deep into his realism through the analysis of Mise-en-Sc$\grave{e}$ne.

Optical properties were studied at the fishing ground of anchovy in the southern part of Korea based on seven oceanographic stations from May to August and November to December, 1977. Submarine daylight intensity was measured at intervals of 1m depth in the upper 30 m layer by the underwater luxmeter (Toshiba # 9). The absorption coefficient of the sea water ranged from 0.066 to 0.619 (mean 0.21) for six months. The transparency ranged from 2.6 to 16 meters (mean 8.4m). The relationship between absorption coefficient (n) and transparency (D) was k=1.70/D. The mean water color in this area was 4.8 $(3\~10)$ in Forel scales. The rates of light penetration for daylight at four different depths were computed with reference to the surface light intensity. The mean rates of light penetration were $69.38\%(25.43\~88.10\%),\;30.35\%\;(4.38\~59.46\%),\;12.53\%\;(0.75\~33.51\%),\;5.7\%(0.18\~20.27\%)$ at depths of 1, 5, 10 and 15 m respectively.

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.

The Working Unit of Forestry Management Cooperatives has been organized by the training and extention service center since 1984 so as to take charge of forestry work of Forestry Management Cooperatives, and this study has been carried out in order to find the problem of Working Unit of Forestry Management Cooperatives, and to show how to solve it in the future. We analyzed a material gained by the immediate questionnaires to 33 members of 4 Working Unit of Forestry Management Cooperatives in Ulsan-Kun, and 10 members of Working Unit of Forestry Management Cooperatives in Jinan-Kun between July and August in 1993. Later, we found that there was an almost inactive Working Unit caused by the insufficient work amount, which resulted in inefficient skill and forestry work due to leave of the skilled forestry worker. Though the government concentrates on bringing up the Working Unit centered by the specialized laborer, it is concluded that bringing up the Working Unit should consider local labor market, organization of agriculture and forestry, organization of labor, level of wage, and the amount of forestry work.
