여가는 일상에 지친 피로를 풀어주는데 매우 중요한 요소이다. 특히 주 5일제 근무로 인해 여가를 즐기려는 사람들의 다양한 욕구는 점점 증대되고 있다. 게임은 대학생들에게 하나의 새로운 여가 활동으로 자리 잡고 있다. 과거보다 대학생들은 게임에 대한 욕구가 다양해지고 새로운 것을 추구하지만 개발사들은 비용적인 부분 때문에 대학생들의 욕구를 크게 반영하지 못하고 있다. 이러한 차원에서 본 연구에서는 대학생들의 여가활동 중 게임이용에 대해 어떤 형태를 나타내는지 평가하는데 초점을 맞추었다. 그 결과 하루 평균 3시간미만의 여가활동 중 1~2시간가량 게임을 하고, 재미와 스트레스 해소에 도움이 되기 때문에 많이 이용하는 것으로 나타났다. 온라인 게임과 PC 게임 플랫폼을 좋아하고, 시뮬레이션 게임과 MMORPG를 즐겨하는 것으로 나타났다. 게임 이용시 보통 1~2만원 정도 지불하는 것으로 나타났다. 이와 같은 연구결과를 바탕으로 마케팅 방법을 제안하였다.

일부 지역의 일반인을 대상으로 대체요법에 대한 개인적 인식 정도와 이용경험을 파악하여 대체요법 의 효율적 이용 방안을 연구하고 대체요법의 발전을 모색하는데 그 목적을 두고 본 연구를 시행하였다. 본 연구를 시행하기 위해 전남의 일부 지역 성인의 일반인을 연구자의 편의에 의해 선정하여 300명 을 대상으로 설문조사를 실시하였다. 본 연구를 통하여, 첫째, 대체요법에 대한 지식 정도는 설문에 응답한 응답자 중 ‘약간 안다’ 44.4%였다. 둘째, 대체요법의 ‘이용 경험은 있다.’는 응답자가 22.6%로 매우 낮았으나 이는 설문에 앞서 대체요법 의 범주를 제시하지 않아 대체요법에 대한 용어의 이해 정도가 낮은 이유로 보여 진다. 셋째, 248명의 응답자 중 166명이 대체요법을 이용하고 있다고 응답했다. 이는 대체요법의 범주를 미 리 제시하지 않아 대체요법의 범주에 대한 이해의 차이로 해석되어지며 본 질문 사항에서 대체요법의 범주를 이해한 것으로 보여 진다. 넷째, 연구대상자들이 가장 교육받고 싶은 요법으로 남자는 대체요법을 교육받고 싶은 1순위에 41명 이 침술(수지침, 사혈 등)을 교육받고 싶어 했고, 여자는 대체요법을 교육받고 싶은 1순위에 20명이 요 가를 교육받고 싶어 하였다. 따라서 대체요법 교육에 있어 남녀의 특성을 고려하여 교육을 시킬 때 더욱 효과적이 될 것임을 알 수 있었다. 대체요법에 대한 종류와 그 효능을 입증 할 수 있는 연구와 더불어 체계적인 홍보와 교육에 있어 적 극적인 노력이 필요하다고 사료된다.

Our Natural environment is being destroyed and green area is being reduced by industrialization and urbanization and those cause environmental problems. In result, increased play hour with TV, computer games, video games rather then spend a time in nature and plants in children’s. This problems cause children’s emotional impoverishment and passive-dependence inclination. And made children scruple thinking and judging by themselves and it makes children exposure to social problems. Therefore loss of humanity and crisis are rapidly increase educational standardization and this is the cause to decrease children’s pure sensitivity and feelings and decrease cultivate desirable humanity for advancement of physical, emotional, social, intellectual things. For solution, this paper propose Kid Garden for equally cultivate interests, concern, imagination, internal emotion and feelings and increase children’s curiosity about nature for get back into good relationship between children and nature. On this study, make a model reflects children’s suggestions includes plays what they want to do, materials, safety, color, preferences those are analyzed results through survey analysis bases on Preference-Analysis of Kid Garden, the most preferred Kid Garden is a unreal Garden showed in fairy tale "The Wizard of OZ". We propose a Kid Garden model, it based on preference-analysis to get each details of preference, for experience plays what they want to do, horticulture activities for feel five senses, harmonize with nature in limited interior space and help children to expand their dream and an ideal. Children are growing constantly. During growing process children raise their dream and hope and made healthy ego. Experience various culture and experience of nature will help to cultivate children’s, most of children who live in desolate buildings, humanity. Thus, this paper proposes a Kid Garden which is necessary to children, has various forms and contents for children’s demands. Furthermore, we need to make custom gardens consider of age, area, characteristic of space. And we need well organized and designed educational environment for help to understand about plant and increase horticulture activity time in children education curriculums.

This study evaluated readability by text design of self-guided signs in recreation areas to obtain basic information needed for enhancement of the readability. Data were collected from 401 visitors in the 'Neodeoulgung' area of Mudeung-San Provincial Park by questionnaire survey during October-November, 2004. This study used eight interpretive signs including four signs produced by imitating the existing self-guided signs in Mudeung-San Provincial Park(MPP) and Naejangsan National Park(NNP) and a sign designed by combining only the most appropriate text attributes. The results showed that a sign in NNP and a sign made up by combining only the optimal text attributes showed lower readability than other signs. It may be related with various influential factors on text readability such as text types, text weight, text familiarity, and text arrangement. Especially, the low readability of the sign produced by combination of only the most appropriate text attributes was unexpected. It suggests that text arrangement such as paragraphing, changing lines, and indent may affect readability. Management implications were discussed.

This study assessed the characteristics of emission and cell toxicology of Methylethylketone(MEK) in ambient air of industrial area. MEK is produced by the oxidation of sec-butyl alcohol and used as the solvent for making ink, printing, coating of film, bonding material and drug extraction. The MEK concentrations in the ambient-air of industrial area in Gimhae City was detected in the range of 25.4～1,580 ㎍/㎥ with an average 297.4 ㎍/㎥. The concentration of MEK showed a descending tendency from April to August followed by its increased tendency since then. The effects of MEK on the human lung cancer A549 cells was examined by the generation of Reactive Oxygen Species(ROS) and cytotoxicity. The range of MEK concentration detected in the area induced ROS generation affecting the oxidation state with a little effects on the viability of the cells.

To investigate the effect of NOx and VOCs(volatile organic compounds) on the generation of high ozone episode, examined the hourly variations of ozone, NOx and VOCs concentrations, and calculated the ozone isopleth about maximum ozone concentrations using OZIPR which was presented by U. S. EPA at three sites in Busan. There was some difference by the sites, but decreasing VOCs concentration was effective for reduction of ozone at 22 July, the episode day of 2005. In the year 2006, the episode day was 8 August and the variations of NOx and VOCs concentration was little than variation of ozone. So it was estimated that the photochemical production of ozone was low than transportation of ozone. And the result of the OZIPR modeling was that decreasing VOCs concentration was effective for reduction of ozone.

우리나라의 대표적 향토수종인 소나무 침엽의 지리적 변이를 알아보기 위하여 남한 전 지역을 대상으로 위도와 경도를 30' 간격으로 교차되는 35집단을 선정하고 침엽을 채취하여 형태적 특성을 조사하였다. 침엽길이, 침엽폭, 기공열수, 기공밀도, 거치수, 수지구수가 집단간, 개체간에 많은 차이가 있었으며, 개체간의 차이가 집단간의 차이보다 더 컸다. 기공밀도는 남부지역의 집단들 보다는 북부지역의 집단들이 더 높았으며, 표고가 낮은 지역의 집단들 보다는 표고가 높은 지역의 집단들이 기공밀도가 더 높았다. 거치수는 북부지역의 집단들보다는 남부지역의 집단들이 더 많았으며, 표고가 높은지역의 집단들보다는 표고가 낮은 지역의 집단들이 더 많았다. 수지구 수는 해안에서 거리가 먼 내륙의 집단들 보다는 해안에서 거리가 가까운 집단들이 더 많았다. 그리고 수지구 지수는 동부지역의 집단들 보다는 서부지역의 집단들이 더 높았다. 침엽의 형태적 특성으로 유집분석 결과 3개 군으로 구분되었으며 제III군은 I, II군에 비하여 거치수는 적고, 기공 밀도가 높은 태백산맥 주위의 집단들이었다.

삼백초과식물 2속 2종에 대한 30개 지역별 개체군의 유전적 상관관계를 알아보기 위해 RAPD 분석을 실시하였다. PCR 과정을 통해 증폭된 RAPD 절편들은 300bp에서 2,000bp 사이의 구간에서 관찰되었다. 총 16개의 oligoprimer를 이용한 효소중합반응에서 156개의 유효한 polymorphic band makers를 확인하였고 이러한 자료에 근거하여 2종의 종내 개체군 군집에 대한 UPGMA phenogram을 도출하였다. 이 결과 유집형태에 근거하여 재배지 개체군과 자연집단 개체군과의 구분이 가능하였고 또한 지역별 개체군들끼리 유집되는 결과를 보였다. 2종 모두에서 지역별 개체군중 경남의 개체군과 제주도의 개체군이 전남의 개체군에 비해 유연관계가 밀접한 것으로 밝혀졌다. 따라서 RAPD 분석은 삼백초과 식물의 개체군별 유연관계를 분석하거나 재배집단과 자연집단을 분석하는데 유용한 실험적 방법으로 생각된다.

The contents of five heavy metals such as lead, cadmium, zinc, copper and manganese in soil and vegetables collected from four sites in Busan district with composite sampling method were determined with ICP emission spectrometer. The ranges of their contents in soil were lead, 1.65～4.36 ppm; cadmium, 0.05～0.09 ppm; zinc, 6.33～11.09 ppm; copper, 0.44～1.35 ppm; manganese, 8.40～19.39 ppm, respectively. These contents were lower than the Clarke number. The range of heavy metal contents in four vegetables such as lettuce, radish and its roots, spinach and cabbage were lead, 0.09～0.48 ppm; cadmium, 0.01～0.08 ppm; zinc, 1.81～14.62 ppm; copper, 0.14～1.87 ppm; manganese, 0.71～14.5 5ppm with the order of Zn(7.30 ppm)>Mn(4.35 ppm)>Cu(0.53 ppm)>Pb(0.19 ppm)>Cd(0.04 ppm) in average contents. The average transfer ratio of metals from soil to vegetables was order of Zn(77.8 %)> Cd(37.5 %)>Cu(34.5 %)>Mn(18.6 %)>Pb(6.7 %). In case of the same cultivating soil, the transfer ratio could be expected to the order of spinach<radish<cabbage<lettuce for copper, lettuce≈cabbage<radish<spinach for manganese, respectively.

The air pollutant emission is mainly caused by line sources in urban area. For example, the annually totaled air pollutant emission is known to consist of about 80% of line sources in Daegu. Hence, the appropriate assessment on the air pollutants of line sources is very important for the atmospheric environmental management in urban area. In this study, we made a comparative study to evaluate suitable dispersion model for estimating the air pollution from line sources. Two air pollution dispersion models, ISCST3 and CALINE4 were the subject of this study. The results were as follows; In the assessment of air pollution model, ISCST3 was found to have 4 times higher concentration than CALINE4. In addition, actual data obtained by measurement and estimated values by CALINE4 were generally identical. The air pollution assessment based on ISC3 model produced significantly lower values than actual data. The air pollution levels estimated by ISCST3 were very low in comparison with the observational values.

This study explores the development process of an farmers’ group in Asan City that now plays an important role in the development of organic farming of the region. While increase in income in general may be one of main purposes making farmers join or form a group, the farmers group in Asan, instead, has tried to form a cooperative of local organic farmers. In doing so, they experienced a lot of difficulties and learnt by trial and error. As a result, the farmers’ group has recently developed in terms of business and organisational growth. The growth is not merely due to the growth of organic food markets but also due to the strong internal ties and trust that made possible to expand into food processing as well as to do social and cultural activities for the rural residents. It implies that trust and cooperative identity between farmers should be the most important thing to be locally embedded farmers groups in a specific region.

충북 영동지역 영보가리 광산의 에렉트럼(은함량=60.3~87.6atom.%)-황화광물 광화작용은 선캠브리아기 편마암 내의 단층열극을 충진한 석영맥으로 산출된다. 석영맥은 광물조성이 단순한 괴상이며, 구조적으로 2회에 걸쳐 형성되었다. 산출 광석광물은 비교적 단순하며, 유비철석(비소함량= 31.4~33.4atom.%), 황철석, 섬아연석(철함량 = 4.1~17.6mole% FeS), 방연석, 황동석, 휘은석 및 에렉트럼 등으로 구성된다. 유체포유물연구에 의하면, 광화작용은 CO2+CH4 함량(XCO2+EH4=0.0~0.2)과 저염도 (0~10wt.% NaCl 상당염농도)를 갖는 H2O-CO2-CH4-NaCl계 유체로부터 200˚~370℃의 온도범위에서 진행되었다. 금-은침전은 천금속계 황화광물 보다는 후기, 약 250℃ 근처에서 진행되었고, 유체불혼화에 따라 황화광물 침전 및 H2S 일탈이 야기되면서 주로 냉각 및 유황분압의 감소에 기인하였다.

Allotment gardens with log house in rural area as a rural growth tool are able to adapt to current market mechanisms by communication and promotion techniques. It is important to know what and how allotment garden's users seek their benefits to market segmentations. The primary purpose of this study was to segment and profile the benefits of allotment garden's potential users so as to provide a better understanding of allotment garden in Korea. A self-administered survey was obtained from 298 allotment gardens users in the study area. Four distinct segments were identified based on the benefits; relaxer(23.7%), educator(21.9%), want-it-all gardener(42.3%), and grower(12.2%), and these were profiled with respect to socio-demographics and civic garden-related features. We suggest that the relaxers are target market of allotment gardens with log house because they have willingly intented to pay a higher rent.

This study aims to develop a rational evaluation system which consists of the selection of evaluation items and the estimation of its weight for the Enhancement Program of the Quality of Life for Farmers and Fishermen and Rural Development. This system has two hierarchical steps. The first step shows the evaluation goals which are relevance, efficiency and effectiveness of the program. The second step stands for the evaluation items which have 11 sub-items such as necessity and externalization for the program, rationality of procedures, feedback and monitoring system, budgetary allocations, information activities, impacts on the program, achievements of the goals and so on. A tentative evaluation system was proposed by brainstorming and Delphi method of expert-group. Weighting values of evaluation items were calculated through pair-comparison works of expert group using stepwise matrix sheets by AHP(Analytic Hierarchy Process).

The frequency of tropical nights and tropical days in Busan during summer season (June-August) from 1995 to 2004 were investigated. When air temperature higher than 25 ℃ continuously maintains at night in summer, it is called the occurrence of tropical night. Tropical day is defined that maximum air temperature is higher than 30 ℃. In Jin-Gu and Daeyeon-dong shows a lot of frequency of tropical day and tropical night because there were located in downtown. Relatively, the areas where are located in seaside and riverside show very low frequency. This can be explained the cooling effects of sea and river. The main meteorological characteristics during tropical nights and tropical days is proved pattern of reverse tendency through wind rose. We analyzed heat index and discomfort index during tropical night and tropical day. This study is useful to understand the aspect of urban thermal environment but need some more observation to quantify.
