  • Woodcraft activities have an inseparable relationship with our daily life, and it is a field that needs to be continued because of the value of education for the growing students. The interest in woodworking from childhood to old age is rapidly expanding nowadays, therefore this study has been done to provide images to those who are engaged in woodcraft business and also those who are interested in this field. If we look at the use of wood in our daily life, We can classify it into Architecture, Civil engineering, Furniture, Musical Instrument, Packaging, Recreational instrument, Exercise instrument, Stationery, Daily commodity, and Industrial use. Among them, We examined kinds of stationery and which type of woods were used. As a result of classifying 101 stationery products in 22 countries, stationery materials using wood can be used for Business cards, Envelope houses, Box houses, Pen holders, Locker plates, Stationery baskets, Book holders, Stamps, Paper knives, Bookmarks, and Photo frames. It was found various wooden stationery are made in USA, Japan, UK, Canada etc. And the most frequently used species are hardwoods such as Walnut (Juglans regia), Maple (Acer spp.), Cherry (Prunus serotina), Birch (Betula spp.), Mahogany (Swietenia macrophylla), Tulip (Liriodendron tulipifera Linnaeus), Bubinga (Guibourtia tessmannii J. Leonard), Wenge (Milletia laurentii De. wild), Cocobolo (Dallbergia cultrata Grah), Zebrawood (Microberlinia brazzavillensis A. Chev.) and Ebony (Diospyros spp.).

  • To evaluate the relationship between obesity, diet, physical activity and breast cancer in Thai women, we conducted a case control study with 1,130 cases and 1,142 controls. Informed consent was obtained from all participants and a structured questionnaire was performed by trained interviewers to collect information on demographic and anthropometric data, reproductive and medical history, residential history, physical activity and occupation as well as dietary habits. A significant positive association with an increased risk of breast cancer was observed in women body mass index (BMI) of ${\geq}25mg/m^2$ (OR=1.33, 95%CI 1.07-1.65), the risk being higher in postmenopausal women (OR=1.67, 95%CI 1.24-2.25). In addition, underweight BMI at ages 10 and 20 years showed an inverse association in all women (OR=0.70, 95%CI 0.56-0.88 and OR=0.74, 95%CI 0.59-0.93, respectively) and in those with a premenopausal status (OR=0.69, 95%CI 0.51-0.93 and OR=0.76, 95%CI 0.56-0.99, respectively). Regular exercise was associated with a decreased risk of breast cancer (OR=0.78, 95%CI 0.68-0.98). Interestingly, analysis by type of activity revealed significant protective effects for women who reported the highest levels of walking for shopping (OR=0.58, 95%CI 0.38-0.88). High consumption of vegetables and fruit were associated with a decreased risk of breast cancer, while high consumption of animal fat showed an increased risk in postmenopausal women. In conclusion, our results indicate that obesity and high consumption of animal fat are associated with breast cancer risk, particularly in postmenopausal women, while recreational physical activity has protective effects. It seems that primary prevention of breast cancer should be promoted in an integrated manner. Effective strategies need to be identified to engage women in healthy lifestyles.

  • Background: Physical therapy (PT) plays an important role in the recovery of function following anatomic total shoulder arthroplasty (aTSA). While several PT protocols have been published for these patients, there is no standardized protocol for aTSA rehabilitation. This lack of standardization may lead to confusion between patients and physicians, possibly resulting in suboptimal outcomes. This study examines how PT protocols provided by academic orthopedic surgery programs vary regarding therapeutic goals and activities following aTSA. Methods: PT protocols for aTSA available online from the Accreditation Council for Graduate Medical Education accredited orthopedic surgery programs were included for review. Each protocol was analyzed to evaluate it for differences in recommendation of length of immobilization, range of motion (ROM) goals, start time for and progression of therapeutic exercises, and timing for return to functional activity. Results: Of 175 accredited programs, 25 (14.2%) had protocols publicly available, programs (92%) recommended sling immobilization outside of therapy for an average of 4.4±2.0 weeks. Most protocols gave recommendations on starting active forward flexion (24 protocols, range 1-7 weeks), external rotation (22 protocols, range 1-7 weeks), and internal rotation (18 protocols, range 4-7 weeks). Full passive ROM was recommended at 10.8±5.7 weeks, and active ROM was 13.3±3.9 weeks, on average. ROM goals were inconsistent among protocols, with significant variations in recommended ROM and resistance exercise start times. Only 13 protocols (52%) gave recommendations on resuming recreational activities (mean, 17.4±4.4 weeks). Conclusions: Publicly available PT protocols for aTSA rehabilitation are highly variable. Level of evidence: IV.

  • Oxygen is the final acceptor of electron transport from fat and carbohydrate oxidation, which is the rate-limiting factor for cellular ATP production. Under altitude hypoxia condition, energy reliance on anaerobic glycolysis increases to compensate for the shortfall caused by reduced fatty acid oxidation [1]. Therefore, training at altitude is expected to strongly influence the human metabolic system, and has the potential to be designed as a non-pharmacological or recreational intervention regimen for correcting diabetes or related metabolic problems. However, most people cannot accommodate high altitude exposure above 4500 M due to acute mountain sickness (AMS) and insulin resistance corresponding to a increased levels of the stress hormones cortisol and catecholamine [2]. Thus, less stringent conditions were evaluated to determine whether glucose tolerance and insulin sensitivity could be improved by moderate altitude exposure (below 4000 M). In 2003, we and another group in Austria reported that short-term moderate altitude exposure plus endurance-related physical activity significantly improves glucose tolerance (not fasting glucose) in humans [3,4], which is associated with the improvement in the whole-body insulin sensitivity [5]. With daily hiking at an altitude of approximately 4000 M, glucose tolerance can still be improved but fasting glucose was slightly elevated. Individuals vary widely in their response to altitude challenge. In particular, the improvement in glucose tolerance and insulin sensitivity by prolonged altitude hiking activity is not apparent in those individuals with low baseline DHEA-S concentration [6]. In addition, hematopoietic adaptation against altitude hypoxia can also be impaired in individuals with low DHEA-S. In short-lived mammals like rodents, the DHEA-S level is barely detectable since their adrenal cortex does not appear to produce this steroid [7]. In this model, exercise training recovery under prolonged hypoxia exposure (14-15% oxygen, 8 h per day for 6 weeks) can still improve insulin sensitivity, secondary to an effective suppression of adiposity [8]. Genetically obese rats exhibit hyperinsulinemia (sign of insulin resistance) with up-regulated baseline levels of AMP-activated protein kinase and AS160 phosphorylation in skeletal muscle compared to lean rats. After prolonged hypoxia training, this abnormality can be reversed concomitant with an approximately 50% increase in GLUT4 protein expression. Additionally, prolonged moderate hypoxia training results in decreased diffusion distance of muscle fiber (reduced cross-sectional area) without affecting muscle weight. In humans, moderate hypoxia increases postprandial blood distribution towards skeletal muscle during a training recovery. This physiological response plays a role in the redistribution of fuel storage among important energy storage sites and may explain its potent effect on changing body composition. Conclusion: Prolonged moderate altitude hypoxia (rangingfrom 1700 to 2400 M), but not acute high attitude hypoxia (above 4000 M), can effectively improve insulin sensitivity and glucose tolerance for humans and antagonizes the obese phenotype in animals with a genetic defect. In humans, the magnitude of the improvementvaries widely and correlates with baseline plasma DHEA-S levels. Compared to training at sea-level, training at altitude effectively decreases fat mass in parallel with increased muscle mass. This change may be associated with increased perfusion of insulin and fuel towards skeletal muscle that favors muscle competing postprandial fuel in circulation against adipose tissues.

  • 본 연구에서는 대구시 도시공원의 소요량과 현황을 시기별, 지역별, 규모별로 고찰하여 도시공원의 속성을 구명하고자 한다. 그리고 도시공원 개발에 있어서의 문제점과 앞으로의 개선방안을 모색하고자 한다. 현재의 공원율은 대구시(大邱市) 외곽의 큰 산(山)이 있는 동구(東區), 수성구(壽城區), 남구(南區)에서 높게 나타나고 있다. 이것은 대구의 근교 큰 산들이 자연공원(自然公園), 도시자연공원(都市自然公園)으로 지정되어 있기 때문이다. 결국, 근교의 산(山)이 없고 시계(市界)와 접하지 않은 중구(中區), 서구(西區)에서는 면적이 작은 근린공원과 어린이공원으로 구성되어 있다. 그러나 대구시의 공원, 유원지가 지역적으로 편중되어 있으나 공원간의 연관 관례를 정립하면 녹지계통의 연결이 가능하다. 도심 공원의 조성에 있어서 대구시(大邱市)에는 많은 이전적지(移轉跡地)가 민간부문에 의하여 토지의 소유권과 개발권이 전용되고 있다. 이전적지에 대해 당국에서는 도시 전체적 측면의 종합적 계획 및 검토, 이전적지에 대한 이용에 관해서 시민 의사를 적극적으로 반영하여 도시공간(都市空間)을 효율적으로 개발해야 할 것이다. 도시공원(都市公園)은 도시속의 녹지지점(綠地據點)으로서 도시가 팽창하고 인구가 증가하여 도시환경(都市環境)이 과밀화 될수록 그 중요성은 더욱 증대될 것이다. 따라서 도시공원의 조성(造成)은 형태와 규모에 관계없이 도시생활(都市生活)의 질(質)을 향상 시킬 수 있는 방향으로 나아가야 할 것이다. 도시공원은 주민사회(住民社會)에 있어서 반드시 있어야 할 개방된 공간으로 고려되어야 한다. 현대도시의 개발(開發)과 관리(管理)에 있어서도 도시민(都市民)을 위한 도시민에 의한 도시민의 공간이라는 철저한 인식하에서 이루어져야 한다. 공설과 공공(公共)공간은 누구나 이용할 수 있는 도시의 마당과 같은 것이며, 따라서 공원(公園)은 구미에서 도입된 계획이론과 이념의 차원보다도 우리의 공권(公園)답게 꾸며지고 이용 되어야 한다.

  • Groundwater in the Waikatoregion is a valuable resource for agriculture, water supply, forestry and industries. The 434,000 ha study area comprises the upper Waikato River catchment from the outflow of Lake Taupo (New Zealand's largest lake) through to Lake Karapiro (a man-made hydro lake with high recreational value) (Figure 1). Water quality in the area is naturally high. However, there are indications that this quality is deteriorating as a result of land use intensification and deforestation. Compounding this concern for decision makers is the lag time between land use changes and the realisation of effects on groundwater and surface water quality. It is expected that the effects of land use changes have not yet fully manifested, and additional intensification may take decadesto fully develop, further compounding the deterioration. Consequently, Environment Waikato (EW) have proposed a programme of work to develop a groundwater model to assist managing water quality and appropriate policy development within the catchment. One of the most important and critical decisions of any modelling exercise is the choice of the modelling platform to be used. It must not inhibit future decision making and scenario exploration and needs to allow as accurate representation of reality as feasible. With this in mind, EW requested that two modelling platforms, MODFLOW/MT3DMS and FEFLOW, be assessed for their ability to deliver the long-term modelling objectives for this project. The two platforms were compared alongside various selection criteria including complexity of model set-up and development, computational burden, ease and accuracy of representing surface water-groundwater interactions, precision in predictive scenarios and ease with which the model input and output files could be interrogated. This latter criteria is essential for the thorough assessment of predictive uncertainty with third-party software, such as PEST. This paper will focus on the attributes of each modelling platform and the comparison of the two approaches against the key criteria in the selection process. Primarily due to the ease of handling and developing input files and interrogating output files, MODFLOW/MT3DMS was selected as the preferred platform. Other advantages and disadvantages of the two modelling platforms were somewhat balanced. A preliminary regional groundwater numerical model of the study area was subsequently constructed. The model simulates steady state groundwater and surface water flows using MODFLOW and transient contaminant transport with MT3DMS, focussing on nitrate nitrogen (as a conservative solute). Geological information for this project was provided by GNS Science. Professional peer review was completed by Dr. Vince Bidwell (of Lincoln Environmental).

  • This research intends to survey family environment, health behavior and health status of the students in urban-rural elementary schools and analyze those factors comparatively, and use the result as basic material for school health teacher to teach health education in connection with family and regional areas. It also intends to improve a pupil's self-abilitiy in health care. The subjects involve 2,774 students of urban elementary schools and 583 student in rural ones, who were selected by means of a multi -stage probability sampling. Using the questionnaire and school documents, we collected data on family environment, health behavior and health status for 19 days. Feb. 2nd 1998 through Feb. 20th 1998. The R -form of Family Environment Scale (Moos, 1974) was used in the analysis of family environment(Cronbach's Alpha =0.80). Questionnaires of Health Behavior in School-aged children used by the WHO in Europe(Aaro et al., 1986) and the ones developed by the Health Promotion Committee of the Western Pacific(WHO, 1995)(adapted by long Young-suk and Moon Young-hee(1996)) were used in the analysis of health behavior, as well documents on absences due to sickness, school health room-visits, levels of physical strength, height, weight and degree of obesity were used to determine health status. In next step, We used them with an $X^2$-test, t-test, Odds Ratio, and a 95% Confidence Interval. 1. In two dimensions of three, family-relationship (t=3.41, p=0.001) and system -maintenances(t= 2.41, p=0.0l6) the mean score of urban children were significantly higher than those of rural ones. In the personal development dimension however, there was little significant difference. Assorting family environment into 10 sub-fields and analyzing them, we recognized that urban children were superior to rural children in the sub-fields of expressiveness (t =3.47, p=0.001), conflict (t=0.48, p=0.001), active-recreational orientation (t = 1.97, p=0.049) and organization (t=4.33, p=0.000). 2. Referring to the Odds Ratios of urban-rural children's health behaviors, urban children set up more desirable behavior than rural children wear ing safety belts (Odds Ratio =0.32, p=0.000), washing hands after meals(Odds Ratio = 0.43, p= 0.000), washing hands after excreting (Odds Ratio = 0.39, p=O.OOO), washing hands after coming - home ( Odds Ratio = 0.75, p = 0.003), brushing teeth before sleeping(Odds Ratio =0.45, p=0.000), brushing teeth more than once a day (Odds Ratio =0.73, p=0.0l2), drinking boiled water (Odds Ratio = 0.49, p=0.000), collecting garbage at home(Odds Ratio=0.31, p=0.000) and in the school(Odds Ratio =0. 67, p=0.000). All these led to significant differences. As to taking milk(Odds Ratio = 1.50, p=0.000), taking care of eyesight(Odds Ratio=1.41, p=0.001) and getting physical exercise in(Odds Ratio = 1.33, p=0.0l9) and outside the school(Odds Ratio = 1.32, p=0.005), rural children had more desirable behavior which also revealed a significant difference. There was little significant difference in smoking, but the smoking rate of rural children(5.5%) was larger than that of urban children(3.9%). 3. Health status was analyzed in terms of absences, school health room-visits, levels of physical strength, and the degree of obesity, height and weight. Considering Odds Ratios of the health status of urban-rural children, the health status of rural children was significantly better than that of the urban ones in the level of physical strength(t=1.51, p=0.000) and the degree of obesity(t=1.84, p=0.000). The mean height of urban children ($150.4{\pm}7.5cm$) is taller than that of their counterparts($149.5{\pm}7.9$), which revealed a significant difference (t =2.47, p=0.0l4). The mean weight of urban children($42.9{\pm}8.6kg$) is larger than that of their counterparts($41.8{\pm}9.0kg$), which was also a significant difference(t=2.81, p=0.005). Considering the results above, we can recognize that there are significant differences in family environment, health behavior, and health status in urban-rural children. These results also suggestion ideas for health education. What we would suggest for the health program of elementary schools is that school health teachers should play an active role in promoting the need and importance of health education, develop the appropriate programs which correspond to the regional characteristics, and incorporate them into schools to improve children's ability to manage their own health management.

  • 본 연구는 비교적 광역규모인 낙동강 약 35km를 대상으로 어느 공간이 환경친화적 친수 휴양공간으로서 개발잠재력이 큰지에 대한 적지선정의 타당성을 검토해 보고, 또한 향후 이 지역의 광역권 휴양계획 수립을 위한 기초자료 제공 및 타 지역으로의 적용가능성이란 측면에서 새로운 방법론을 모색해 보는데 그 의의를 찾을 수 있었다. 연구결과를 요약해 보면 아래와 같다. Mesh법에 의한 사례지의 격자구분 결과, 총 42개의 격자단위로 분류되었다. 또한, 평가지표의 분석결과, 총 20개로 설정되었으며, 이들은 중요도에 따라 다시 4가지의 휴양활동 유형별로 귀속되었다. 각 휴양활동 종류별 평가지표들의 중요성 정도를 분석해 본 결과, 필수요소는 물 이용을 중심으로 한 친수 위락활동공간에서 8개로 가장 많은 지표를 포함하고 있었으며, 충분요소는 정적 친수 휴양활동 공간에서 12개로 가장 많았다. 구분된 각 격자별 최소 요구조건 평가인 1차 평가를 수행한 결과, 최소요구조건을 충족시키고 있는 격자는 전체 42개 중 32개의 격자로 나타났다. 휴양활동 종류별로 최소요구조건을 충족시키는 격자는 연구대상지의 전 구간에 걸쳐 비교적 고른 분포를 나타내고 있음을 확인할 수 있었다. 구체적인 부지 평가인 2차 평가 결과, 우선 자연체험 및 경관생태학습 공간에서는 총 6개의 격자, 운동 및 레크리에이션 중심의 수변 위락활동 공간은 총 4개, 물 이용을 중심으로 한 친수 위락활동 공간으로서는 1개 격자, 마지막으로 정적 친수 휴양활동 공간에 대한 각 격자별 적합성 평가 결과에서는 총 4개의 격자가 매우 적합한 것으로 분석되었다. 그러나 본 연구에서 수행된 격자단위 평가 결과는 지형적 조건 등으로 인해 인접 격자로 확대 및 축소될 수 있다. 따라서 경계의 재조정을 통한 격자형태 및 크기의 변형을 고려한 기본계획을 수립하는 것이 보다 더 타당할 것으로 사료된다.

  • 본 연구는 북한산국립공원 둘레길의 정상정복형 수직 탐방객의 분산 효과를 진단하고, 둘레길 구간별 특성화 및 개선방향을 제공하는데 목적이 있다. 조사방법은 이용자 자기 기입식 조사 방법으로 현장조사를 통해 둘레길 전체 21개 구간에서 탐방객을 대상으로 이루어졌다. 둘레길 조성 후 북한산 탐방 횟수가 증가하였으며, 둘레길에 처음 방문한 만 18~29세의 젊은 연령층 비율이 높아, 둘레길로 인해서 새로운 계층의 탐방객이 유입된 것으로 판단된다. 북한산 정상탐방 이용빈도는 '감소하였다' 7.6%, '증가하였다' 46.2%로 정상정복형 수직 탐방객의 분산효과는 아직 없는 것으로 판단된다. 둘레길 만족도는 7개의 측면 중 여가장소적 측면이 3.74, 보행만족 측면이 3.61로 높았고, 역사문화 측면이 3.09로 가장 낮았다. 둘레길 구간별 특성과 탐방객의 방문동기, 만족도 결과를 통해 둘레길이 가벼운 운동, 산책 등의 건강증진을 위한 개념으로 인식되고 있음을 보여주었다. 그러나 저지대 길에서의 자연, 생태, 역사, 경관 등 국립공원 자원에 대한 다양한 시각의 이용문화가 창출되어 장기적으로 긍정적인 효과를 예상할 수 있었다. 또한 둘레길의 구간별 특성과 여건, 인프라 및 프로그램에 따라 차이가 있어 둘레길 구간별 특성을 고려한 인프라 및 프로그램이 보완된다면 장기적으로 정상탐방객의 저지대 탐방문화 유도 효과를 기대할 수 있을 것이다.
