In order to save costs and enhance quality in construction without damaging the environment, the VE/LCC analysis method is increasingly used. This study was carried out to conduct a value analysis for the ecological restoration of a slope considering life cycle cost and performance. The construction conditions were classified into three types(A, B, C) according to the condition of each base. Three construction methods for slope ecological restoration were selected by each condition. Eventually, a value analysis was conducted for total nine conditions by analyzing the life cycle cost and performance. The gradient of slope and base of Condition 1 were below 1:1.2 and general soil, while condition 2 and 3 were below 1:1.0(reaping rock) and below 1:0.7(soft rock, blasted rock), respectively. A value analysis was conducted based on the value estimated via life cycle cost and performance analysis. The result showed that the B construction method had the highest value in Condition 1 as it showed 108.4, while A and C showed 90.3 and 45.8, respectively. When it comes to Condition 2, Construction Method A indicated the highest value as it showed 89.1(B: 47.5, C: 47.0). In Condition 3, Construction Method A(89.1) was the highest, while B and C showed 55.4 and 40.2, respectively. Based on the result of this study, in order to make a reasonable decision that can enhance quality and reduce costs in slope ecological restoration, the slope ecological restoration method must be reviewed in consideration of life cycle cost and performance.

A protected area means a space designated and protected by law from development pressure and environmental pressure. It is mainly designated to protect specific ecosystems, natural landscapes, and cultural resources from irrational development (or damage), and involves policies of the public sector such as central and local governments. The United Nations Educational, Scientific and Cultural Organization (UNESCO) has conducted conservation and restoration projects for preserving natural ecosystems and genetic resources. In order to conserve the ecosystem in the protected area, national and public organizations purchase private land and use it ecologically; in addition, ecological restoration project is carried out for the purpose of creating waterside ecological belt or preserving ecosystem. Land acquisition refers to the land where highly influenced by the water quality and need to restore, and purchased by negotiating with the landlord. Although the nation and public institution carried out ecosystem restoration project for partial purchase land in order to conserve ecosystem, it is below the expected effect due to lack of comprehensive management system and have some problems in restoration project and unification of management institutions. Land acquisition in Donggang River Basin Ecological Conservation area is initiated in 2005 for creating income of local residents and ecological restoration. However, the lack of overall management and awareness resulted in poor vegetation growth and poor response by local residents due to terrain exposure. As such, there is insufficient research on the current situation and systematic integrated management although the number of land acquisition is increasing year after year. Futhermore, overall recognition and follow-up monitoring of eco-restoration are still inadequate. Therefore, the survey on the awareness of the purchase land ecosystem restoration project is necessary for the efficient restoration project and establishment of the management strategy for land acquisition in the future. Therefore, in this study, we provide fundamental materials on further research projects by carrying out research on the awareness of ecological restoration projects in the Donggang River basin ecological preservation area.

The purpose of this study was to develop a list of plants that adapted to the aquatic environment in urban areas based on the list of plants surveyed through literature review and field surveys, and to classify the types of vegetation according to the five categories of plant distributions set by the U.S. Fish and Wildlife Service (1988) in the aspect of the adaptability of plants to the aquatic environment.Results of the classification by category according to the adaptability to the aquatic environment for the plant species surveyed through literature review and field surveys showed that there are 45 species of OBL, 96 species of FACW, 66 species of FAC, and 94 species of FACU, totaling 650 species. In addition, a total of 50 species excluding exotic species, endangered species, and naturally introduced plants are proposed as appropriate plants for the urban aquatic environment that will be artificially constructed. The results of the study can be utilized as the basic information for maintaining diversity and stability of the ecosystem during the restoration of water ecology; they can serve as useful data for the development of an optimum vegetation model when planting in water spaces in the future and preparing proper planting plans for each space. In addition, it is believed that the information will be useful in wetland identification and evaluation by observing plant species that appear only in wetlands.

FMS 기능성 동작훈련이 중국 대학 에어로빅 선수의 신체자세 조절 능력에 미치는 영향에 관한 실험적 연구

이란(Lan Li),인전(Zhen Yin) 안전문화포럼 2023 안전문화연구 Vol.- No.25

본 연구는 FMS 기능성 동작 훈련이 에어로빅 선수의 신체 자세 조정력에 미치는 영향을 탐구하고, FMS 기능성 동작 훈련이 에어로빅 선수의 신체 능력 촉진에 대한 응용 방법을 탐구한다. 에어로빅 운동에서 신체 자세 제어 능력은 기술 동작 표현, 형태 예술 미감 전시와 에어로빅 경기 성적 평가의 중요한 기준이다. 체력훈련은 가장 기본적인 신체자세통제능력의 제고방식이고, 그중 FMS 기능성동작훈련은 최근 몇년간 신흥체력훈련모식으로서 전통적인 체력훈련보다 기능방면의 훈련을 더욱 중시하고 목적성있게 운동선수의 자신을 제고시키지 못하며 동작에 대한 요구가 비교적 높은 기술동작에 대해 비교적 좋은 제고효과가 있다. 대학생 에어로빅 선수 40명에게 무작위로 전통 체력훈련조(Traditional physical training Group, T, N=20), FMS 기능성 동작훈련조(Functional training Group, F, N=20)으로 나뉜다. 대조팀은 전통적인 체력훈련방법을 채택하고 기능성훈련조은 FMS의 기능성동작설계에 기초한 훈련방안을 채택한다. 12주 FMS 기능성 훈련을 설정하여 실험조의 선수들에게 40min/회 훈련하도록 개입한다. 결과는 훈련 전과 비교했으면 전통적인 체력 훈련조과 FMS 기능성 동작 훈련팀이 관여한 후, 피실험자 FMS 테스트는 6개의 운동성 동작이 모두 현저하게 향상되었지만(P<0.05), 직선 활 스쿼트, 능동 직교 리프팅 테스트는 현저한 차이가 없었다는 것이다(P>0.05). 에어로빅의 동적 운동과 정태에서의 신체 자세 조정력은 FMS 기능성 동작 훈련조에서만 현저하게 향상되었다(P<0.05). 결론은 FMS 기능성 훈련은 에어로빅 선수의 신체 통제 능력과 이동 과정에서의 신체 자세 조정력을 비교적 잘 촉진할 수 있어 대학생 에어로빅 선수의 체력 훈련에서 더욱 응용하고 보급하기에 적합한 것으로 생각된다. 12주간의 훈련 후 실험군의 각종 지표의 점수 상승률은 실험 전과 대조군보다 유의하게 높았고, FMS 테스트 결과에서 유의하게 개선되었으며, 실험군의 효과는 대조군보다 우수하여 운동 손상의 발생률을 감소시켰으며, 실험군 선수의 신체 안정성, 유연성 및 비대칭성은 개선되었지만, 능동적인 직각 상승 및 직선 런지 스쿼트에 대한 효과는 명확하지 않았다. 정적 운동면 변화 조건에서 신체 자세 제어 능력 테스트에서 실험군과 대조군의 8단계 복교, 5단계 측교 및 육앙교가 유의한 차이를 보였고 실험 구성 결과가 대조군보다 우수함을 알 수 있으며 실험군의 전후 비교가 유의한다. FMS 기능성 동작 훈련이 에어로빅 선수의 정적 운동면의 신체 자세 제어 능력을 향상시킬 수 있음을 보여준다. 동적 운동 방향 변화 조건에서 에어로빅 선수의 신체 자세 제어 능력 테스트 결과, 실험군의 실험 전후 에어로빅 조합 스텝의 T자형, W자형 및 Y자형 테스트의 향상 효과가 대조군보다 우수하며, 각 지표는 그룹 내에서 유의한 차이를 보이며, 이는 FMS 기능적 동작 훈련이 에어로빅 선택반 에어로빅 선수의 신체 자세 제어 능력을 향상시켰음을 나타낸다. The present study explores the effects of FMS functional movement training on aerobic athletes' body posture coordination, and explores the application of FMS functional movement training to the promotion of aerobic athletes' physical performance. In aerobic exercise, body posture control ability is an important criterion for the expression of technical movements, the display of form art aesthetics, and the evaluation of aerobic competition performance. Physical training is the most basic way to improve body posture control, and FMS functional movement training is an emerging physical training mode in recent years, which attaches more importance to functional training than traditional physical training, does not improve athletes' self-confidence in a purposeful way, and has a relatively good improvement effect on technical movements with relatively high movement requirements.40 college aerobic athletes were randomly divided into two groups: Traditional physical training Group (T, N=20) and FMS functional movement training Group (F, N=20). The control group adopts the traditional physical training method, and the functional training group adopts the training method based on the functional movement design of FMS. The results showed that compared with before training, after the traditional physical training group and the FMS functional movement training group intervened, the subjects' FMS test improved significantly in all six motility movements (P<0.05), but there was no significant difference in the straight bow squat and active orthogonal lifting test (P>0.05). The body posture coordination in the dynamic movement and static movement of aerobics was significantly improved only in the FMS functional movement training group (P<0.05).Conclusion: FMS functional training can relatively well promote aerobic athletes' body control ability and body posture coordination in the movement process, which is suitable for further application and dissemination in the physical fitness training of college aerobic athletes.After 12 weeks of training, the scores of various indicators of the experimental group were significantly higher than those of the control group before the experiment, and the results of the FMS test were significantly improved; the effect of the experimental group was better than that of the control group, reducing the incidence of exercise damage; the physical stability, flexibility and asymmetry of the experimental group athletes were improved, but the effect on active right angle rise and straight lunge squat was not obvious. In the body posture control ability test under the static movement plane change condition, the 8-step ventral bridge, 5-step lateral bridge and hexagonal bridge of the experimental group and the control group showed significant differences, and the experimental configuration results were better than the control group, and the before-and-after comparison of the experimental group was significant.It shows that FMS functional movement training can improve the body posture control ability of aerobic athletes in the static movement plane. In the test of aerobic athletes' body posture control ability under the condition of dynamic movement direction change, the results show that the improvement effect of the T-shaped, W-shaped and Y-shaped tests of aerobic combination steps of the experimental group before and after the experiment is better than that of the control group, and each indicator has a significant difference within the group, indicating that FMS functional movement training has improved the body posture control ability of aerobic athletes.

In this study, ecological investigation was performed on Yong-neup, Daeam-san for 5 times. This area is considered DMZ zone located between Yanggu-gun and Inje-gun, Gangwon-do, where has been recognized highly valuable for ecological preservation. As a result, Sphagnum and hydrophobic vegetation were found in Little Yong-neup, revealing its characteristics of high moor, where as no Sphagnum were found in Baby Yong-neup. Thereby, the carnification has been investigated in both Little Yong-neup and Baby Yong-neup. A main cause of damage was associated with the creation of stating rink and increases of visitors. The damages of vegetation in Little Yong-neup and Baby Yong-neup have been intensified by road construction or uses of groundwater while relocating military troops to upper stream of Little Yong-neup and Baby Yong-neup, further causing the damages of water circulation system and soil erosion. These artificial factors have caused the carnification of wetland protection areas including Little Yong-neup. The terrestrial vegetations, such as Plantago asiatica, Geranium Koreanum and Artemisia feddei have increased compared to current survey conducted by the Ministry of Environment. 5 endangered species, such as Lychnis wilfordii and Trientalis europaea and 5 other introduced species, such as Aster pilosus and Taraxacum officinale were found. 10 different species of mammal and 2 species of amphibian were investigated; and in addition to this, a original form of Sphagnum fens, the remaining wetland was found. Therefore, this study is to identify the causes of damages in Little Yong-neup and Baby Yong-neup through their ecological survey and accordingly proposing a direction for ecological restoration through the improvement of water circulation system, creation of habitats for plant and animal, restoration of vegetation through eco-friendly materials and indigeneity, relocation of the current military troops, securing of structural stability.

Wetlands occupy an important ecological position on the earth, carrying out very important functions and roles both ecologically and hydrologically. However, due to past industrialization, not only wetland areas but also the biodiversity of organisms has severely decreased due to several artificial interferences and damage as wetlands began to be perceived simply as targets for development and reclamation. However in recent times, with the importance of wetlands coming to the fore, the assessment of the function and value of wetlands is being made for their wise use and systematic maintenance. Accordingly, this study targeted the Jilnal Wetlands located in Haman, Gyeongnam, and conducted a functional appraisal of this wetland using the modified HGM Model which was modified & developed appropriately for the actual conditions of our country. The result of its appraisal by selecting the Upo Wetland as the reference wetland, which is a criterion of the index, showed a comparatively positive functional index with 0.89 of the Upo Wetland average. This means that the Jilnal Wetland carry out more than 89% of the functioning of the Upo Wetland. In this regard, it is thought that the Jilnal Wetland could carry out the wetland functioning equivalent to that of the Upo Wetland through a little more systematic management.

Objective: Although serum ferritin is considered the best measure of total body iron, with low levels indicating iron deficiency, recent studies have shown that high levels are associated with gestational diabetes, premature birth, and low birth weight. This study aimed to analyze the association between serum ferritin levels in the third trimester of pregnancy and low birth weight and preterm birth. Methods: This study included pregnant women who delivered a single fetus at Kangwon National University Hospital between January 2009 and December 2013 and in whom serum ferritin levels were measured between 28 and 34 weeks of gestation. The association between serum ferritin levels measured in the early third trimester of pregnancy and preterm birth and low birth weight infants was analyzed. Results: A total of 1,079 women fulfilled the study criteria and had their serum ferritin level measured during the third trimester (28-33.9 weeks of gestation) and later delivered at Kangwon National University Hospital. Comparison of the group with serum ferritin levels above the 75th percentile and those below the 25th percentile at the beginning of the third trimester revealed that the incidence of preterm births (<34 weeks of gestation, <37 weeks of gestation) and low birth weight were significantly higher in the group with serum ferritin levels above the 75th percentile than those below the 25th percentile (p<0.05). When variable factors were controlled through multiple regression analysis, the group whose serum ferritin levels were above the 75th percentile at 30-31.9 weeks of gestation had the highest risk of preterm birth before 34 weeks of gestation (adjusted odds ratio [OR], 7.85; 95% confidence interval [CI], 1.32-29.9) and low birth weight (adjusted OR, 6.49; 95% CI, 2.10-20.0). Conclusion: In this study, when serum ferritin was high in the third trimester of pregnancy, it was significantly increased with preterm birth (<34 and 37 weeks) and low birth weight. In particular, when serum ferritin levels were high at 30-31.9 weeks of gestation, the risk of premature birth before 34 weeks and low birth weight was statistically highest.

This study was conducted to establish inventory and propose conservation strategy of ‘village wetlands’ in Cheonan. As results, the village wetlands are defined as such places as palustrine wetland, village embankment, agricultural reservoir or small reservoirs located in or near the village and related to everyday life or farming. Firstly 791 provisional village wetlands were identified in Cheonan by using Arc-GIS 10.1, then 104 wetlands were defined as village wetlands and listed the inventory of Cheonan Village Wetlands after being validated through their area (greater than 1,000m2), satellite images, Korea Land Information System, land use map, land coverage map and field survey. Finally the 49 wetlands were selected for detailed surveying, and function assessment. As the result of the wetland function assessments, 11 wetlands were found to have ‘high’ wetland function (conservation) 30 wetlands were ‘average’ (enhancement) and 8 wetlands were ‘low’ (restoration or enhancement). Enhancing biodiversity and ecosystem services through ecological management of wetlands in Cheonan and connecting with an ecological network were proposed.

2005년부터 제조원가명세서는 강제공시 항목에서 자발적 공시항목으로 변경되었다. 제조 원가명세서가 공시되면 기업의 원가정보가 경쟁업체게 유출되어 원가경쟁력이 저하되는 부정적 측면이 존재함에도 불구하고 제조원가명세서의 자발적 공시하는 기업은 특수한 경제적 유인이나 기업특성이 존재할 것이라 판단하였다. 이에 제조원가명세서 공시기업의 특성에 관한 선행연구와 자발적 공시를 포함한 자본비용의 영향요인에 관한 선행연구의 결과를 바탕으로, 자본비용이 높게 책정될 가능성이 높은 기업에서 제조원가명세서 공시를 통해 자본 비용을 감소시키는지를 실증분석 하였다. 2006년부터 2010년까지 한국거래소에 상장된 코스피와 코스닥 기업을 대상으로 분석을 수행한 결과는 다음과 같다. 첫째, 차이분석에서 제조원가명세서를 자발적으로 공시하는 기업은 미공시기업에 비해 타인자본비용이 낮게 나타났다. 둘째, 실증분석에서 제조원가명세서를 자발적으로 공시하는 기업에서는 타인자본비용이 낮게 책정되는 것으로 나타났다. 이상의 연구결과를 통해 자본투자자에게 투자위험이 높게 평가될 수 있는 기업에서는 제조원가명세서를 자발적으로 공시하여 기업과 자본투자자 간의 정보불균형 완화를 통해 자본 비용을 감소시키려는 유인이 존재하고 있음을 발견하였다. This study investigates how voluntary disclosure of the schedule of manufacturing cost is associated with cost of debt. The samples are consisted of 2,310 non-banking firm-years with december fiscal year listed on KRX from 2006 to 2010. The data of disclosure of the schedule of manufacturing cost, other firm-specific data is collected from Kis-Value Ⅲ and Beta is collected from Fn-Guide. The empirical results are as follows. First, there are significant differences in firm characteristics between the firms that voluntary disclose schedule of manufacturing cost and the firms that do not disclose schedule of manufacturing cost. Voluntary disclosing firms have lower cost of debt than the firms that do not disclose schedule of manufacturing cost. Second, disclosing schedule of manufacturing cost decreases cost of debt. Our findings suggest that the firms to have risk of taking higher cost of debt may try to decrease cost of debt through voluntary disclosure schedule of manufacturing cost.
