이 연구는 영남대학교가 소장하고 있는 고지도 자료 중 총 48점의 울릉도․독도 관련 지도를 통해 독도가 한국의 영토인 근거를 제시하고자 한다. 지도 자료를 통해 독도의 영토주권을 재확인하고, 영남대학교가 소장하고 있는 독도 관련 고지도의 가치를 높이는 동시에 독도 연구의 구심점으로서 영남대학교 독도연구소의 위상을 확고히 하는데 그 의의를 두고 있다. 18세기이후 한국의 고지도, 특히 강원도 폭상에 나타난 ‘독도’의 위치는 ‘독도’가 울릉도의 오른쪽(동쪽) 또는 왼쪽(서쪽), 아래쪽(남쪽), 아래왼쪽(남서쪽), 아래오른쪽(남동쪽)에 각기 다르게 표시된 것을 볼 수 있다. 그렇다면 독도는 정확히 어디에 위치하고 있는 것인지, 각기 다른 위치로 표시된 독도가 현재의 독도위치와 같은 곳으로 어떻게 해석할 수 있는지에 대하여도 지도의 현황 조사를 통해 살펴볼 수 있다. 영남대 소장 독도 관련 지도의 현황과 특징을 조사한 결과 조사대상 지도 가운데는 독도와 울릉도의 위치가 현재의 위치가 아닌 경우도 있었는데, 이것은 당시의 지도 제작법의 유형에 따른 현상으로 당시 고대 시대의 사람들은 독도와 울릉도의 위치와 크기를 정확하게 알고 있었고, 후대 시대로 오면서 지도로 나타난 증거자료가 되었다. 영남대 소장 독도 관련 지도는 이미 조선시대 이전부터 당시 사람들이 동해 바다에는 두 개의 큰 섬(울릉도·독도)이 있었음을 명확히 인지하고 있었다는 사실과 어로활동 등을 통해 두 섬과 인근해역을 이용해왔다는 명백한 사실을 확인시켜주고 있는 중요한 자료이자 증거라고 볼 수 있다.

This paper analyzes the profitability of the Private Finance Initiative(PFI) ports and proposes the application plans of the R-project(Rehabilitate project) for old ports to attract and activate private investment in the port industry. The R-project of old ports can reduce the government’s financial budget and provide improved facilities for users more quickly than the public sector comparator. Before suggesting the R-project for old ports, the profitability of the currently operating 11 companies of the PFI ports are analyzed using the four ratios of profitability, and the results show that all the companies indicate low profitability, except for the top three companies. To apply the R-project, the three types of R-project ports are categorized as maintaining the function of the port, changing the function of the port, and mixing the function of the port. Additionally, three obstacles and improvement measures are suggested; attracting private business, legal issues, and administrative procedures. This study is conducive to the policy making for the port renewal and the activating PFI for the port industry

The purpose of this study was to investigate the egg freshness and eggshell characteristics of old laying hens by adding sea urchin shell powder to the feed of such hens to achieve the objectives continuously pursued by environmental management, such as business profitability and waste resource utilization. A total of 90 Hy-Line Brown layers (66 weeks of age) were randomly divided into 2 treatments with 3 replicates, each of which consisted of 15 older layers, for 4 weeks. These treatments included a control (i.e., 0%) and 2% sea urchin shell powder. The 2% supplementation of sea urchin shell powder increased the Haugh unit (HU) at 2 and 4 weeks and eggshell strength at 4 wks compared to the controls (p<0.05). The HU at 0 weeks, eggshell thickness from 0 through 3 weeks, and eggshell strength at 0 and 2 weeks were not different between treatments (p>0.05). These results suggest that the addition of 2% sea urchin powder to the feed of laying hens improves egg freshness and eggshell strength in old laying hens.

The purpose of this study is to examine the differences of use behavior and environmental perception of a park and to analyze the influence of environmental perception factors on park satisfaction among 7 parks in Suseong-gu, Daegu. The data from the 255 questionnaires of young adults (30-59) and old adults (more than 60) who use the park more than once a week were used for the analysis. In terms of park use behavior, young adults used the park for walking and jogging mainly on weekday evenings, while old adults used the park for walking and rest mainly during weekday daytimes. In addition, old adults used the park more times a week than young adults, and spent more time in the park. In the analysis of the environmental perception of the park, similar results were found in both age groups but overall, old adults were more satisfied with the park environment than the young adults. As a result of analyzing the influence of environmental perception factors, it was determined that park satisfaction in young adults has a significant influence on 'use amenity', 'use convenience', 'facility suitability', and 'landscape diversity' in this order. On the other hand, park satisfaction for old adults has an influence on 'use amenity', 'facility suitability', and 'use convenience' in this order. The findings of this study can be used as an effective basic data for future park planning considering age groups.

사과 ‘후지’/M.9 포트묘목 개발을 위해 질소시비농도에 따른 생장특성을 조사하고, 포트 우량묘목 생산에 적합한 질소시비 농도와 잎의 무기영양성분 함량 및 토양 화학성의 안정성을 확인하였다. 질소시비농도가 높아질수록 묘목의 생장은 증가되 었고, 특히 16 mM 처리가 수체 생장에 가장 좋았으며, 우량묘목 판단기준에 부합하였다. 32 mM 이상의 고농도는 오히려 생장 을 감소시켰다. 잎의 무기영양성분 함량은 8, 16 mM 처리구에서 기존 사과과원의 적정수준보다 높았고, 이러한 무기영양성분은 정식 후 수체 생장에 도움이 될 것으로 생각되었다. 토양 화학성 또한 8, 16 mM 처리구에서 안정적이었다. 따라서 수체 생육, 잎의 무기영양성분, 포트 내 토양화학성을 고려한 결과, 사과 ‘후지’/M.9 우량 포트묘목 생산을 위한 적정 질소시비량은 16 mM로 판단되었다.

Ginseng (Pnanx ginseng C. A. Meyer) is famous worldwide, and is very important cash crop and medicinal herb in Korea. It takes four to five years to produce harvestable ginseng roots, and ginseng is attacked by several pathogens during cultivation. We investigated the disease rate caused by ginseng root rot from 6 years old ginseng cultivation fields (Chungnam; 9 fields, Chungbuk; 11 fields, Gangwon 5 fields). The highest disease severity was Dangjin D (2.9) and the lowest one was Gaesan C (0.6). Of the 625 isolations, 340 isolations were classified as Ilyonectria radicicola and Fusarium solani. Finally, genetic diversity of I. radicicola and F. solani was confirmed by sequence analysis. Among the I. radicicola group, I. mors-panacis, which is known as highly virulent pathogen, and I. liriodendri, I. robusta and I. cyclamicicola, which are weakly virulent pathogens, were identified. In the case of F. solani, it is divided into two groups, but it is necessary to conduct diversity research through genetic analysis and pathogenetic studies using various markers. Based on these results, it could be used as a basic data for control of ginseng root rot pathogens.

Background: Ginseng produced by hydroponics can be cultivated without using agricultural chemicals; thus, it can be used as a raw materials for functional foods, medicines, and cosmetics. This study aimed to determine the optimal harvesting time to obtain the highest levels of ginsenoside and ginseng, as this was not previously unknown. Methods and Results: One-year-old organic ginseng seedlings were transplanted and cultivated using hydroponics for 150 days in a venlo-type greenhouse, using ginseng nursery bed soil and a nutrient solution (NO3 −-N; 6.165, P; 3.525, K; 5.625, Ca; 4.365, Mg; 5.085, S; 5.31 mEq/ℓ). Ginsenoside content and fresh and dry weights were higher at 120 days after transplanting than at 30, 60, 90, and 150 days. Total ginsenoside content was 11.86 times higher in the leaf and stem than in the root at 120 days after transplanting. Ginsenosides F1, F2, F3, and F5 were detected in ginseng leaves and stems. These chemical compounds are known to be effective in altering skin properties, including whitening, anti-inflammation, and anti-aging. Conclusions: Optimal harvesting time for ginseng cultivated using hydroponics was 120 days after transplanting when the biomass and ginsenoside content were highest.

Background: Some phenolics detected in the soil may inhibit the seed germination and seedling growth of ginseng (Panax ginseng). This study investigated the effect of irrigation and ginseng root residue addition on the soil microbial community and root rot disease in 2-year-old ginseng. Methods and Results: Each 20 ℓ pot was filled with soil infected with ginseng root rot pathogens, and irrigated daily with 2 ℓ of water for one month. After the irrigation treatment, ginseng fine root powder was mixed with the irrigated soil at a rate of 20 g per pot. In descending order, NO3 −, electric conductivity (EC), exchangeable Na (Ex. Na) and K (Ex. K) decreased due to irrigation. In descending order, NO3 −, EC, Ex. K, and available P2O5 increased with the additon of ginseng powder to the soil. The abundance of Trichoderma crassum decreased with irrigation, but increased again with the incorporation of ginseng powder. The abundance of Haematonectria haematococca increased with irrigation, but decreased with the incorporation of ginseng powder. The abundance of Cylindrocarpon spp. and Fusarium spp., which cause ginseng root rot, increased with the incorporation of ginseng powder. The abundance of Arthrobacter oryzae and Streptomyces lavendulae increased with irrigation. The abundance of Streptomyces lavendulae decreased, and that of Arthrobacter spp. increased, with the incorporation of ginseng powder. Aerial growth of ginseng was promoted by irrigation, and ginseng root rot increased with the incorporation of ginseng powder. Conclusions: Ginseng root residues in the soil affected soil nutrients and microorganisms, and promoted ginseng root rot, but did not affect the aerial growth of ginseng.

Background : Root rot is a major factors of replanting failure in ginseng cultivation. Some of the phenolics detected in the soil could inhibit the seed germination and seedling growth of ginseng. Methods and Results : Water of 2 ℓ was irrigated per pot (20 ℓ) into the soil infected with ginseng root rot pathogens for one month every day. After the irrigation treatment, the powder of ginseng fine root of 20 g per pot was mixed with the irrigated soil. NO3 -, electric conductivity (EC), exchangeable Na (Ex. Na) and K (Ex. K) were decreased in descending order by irrigation. NO3 -, EC, Ex. K, and available P2O5 were increased in descending order by incorporation of ginseng powder into soil. Trichoderma crassum was decreased by irrigation, but it was increased again by incorporation of powder. Haematonectria haematococca was increased by irrigation, but it was decreased by incorporation of powder. Cylindrocarpon spp. and Fusarium spp. causing ginseng root rot were increased by incorporation of powder. Arthrobacter oryzae and Streptomyces lavendulae were increased by irrigation. Streptomyces lavendulae was decreased, and Arthrobacter spp. was increased by incorporation of powder. Aerial growth of ginseng was promoted by irrigation, and ginseng root rot was increased by incorporation of powder. Conclusion : The residues of ginseng root in the soil affected soil nutrients and microorganisms, and promoted ginseng root rot, but did not affect the aerial growth of ginseng.

Background : Panax ginseng C. A. Meyer is an important medicinal herb and their major pharmacologically active components are ginsenosides. Many studies have reported that various ginsenosides are effective in the treatment of human diseases such as cancer, cardiovascular and alzheimer’s disease. However, it is difficult to create new desirable variation such as increased ginsenosides. Since the frequency of spontaneous mutations is rare naturally and difficult to apply to plant breeding, artificial mutation inductions are necessary to obtain noble genetic resources having desirable traits. Methods and Results : Gamma irradiation was carried out using a 60Co irradiator (3000Ci, Nordion Inc., Ottawa, Canada) of the Korea Atomic Energy Research Institute, Jeongeup, Korea. One-year-old ginsengs were treated at 20, 40, 60, 80, and 100 Gy. The emergence rate was significantly decreased with increasing gamma doses. When irradiated at more than 80 Gy, it did not emerge at all. Survival rate was also significantly influenced by gamma-ray dose. The maximum survival rate were recorded in control. The survival rate of 20 Gy was 22.0% and only 1.0% survived when 40 Gy dose was treated. There was no survival when irradiated at more than 60 Gy. Gamma irradiation also affected the phenotype of emerged plants. The growth of plants derived from irradiated one-year-old ginsengs was decreased and the leaves became variegated or curled. Also, rusty roots resulting from physiological disorders were observed and the rhizomes, which is a kind of dormant bud, were destroyed completely. Conclusion : Based on these results, we estimated the optimal dose for mutation induction by gamma-ray treatment of one-year-old ginseng is to be less than 20 Gy.

Background : This study examines the main growth characteristics, physiological stress, or diseases damage for 3 and 4-years-old ginseng in the new lines cultivated in Gyeonggi for development of new lines of Ginseng. Methods and Results : Eumseong 13, 14 and 15, which are two-years-old seedling in the new line ginseng were transplanted in 7 lines × 9 rows (70 plants)/1.62㎡ in 2015 along with Gumpoong and Yeonpoong as the control lines while Eumseong 16 and 17 as well as Chunpoong as the control line were transplanted in the same way in 2016. The ginseng shading was installed with the front post of 170 ㎝ high and the rear post of 100 ㎝ high using the rear line while as the sun blocking material, the aluminum shade plate was used. As for the new growth lines of 3 and 4-years ginseng in the new growth line, the aerial parts of the ginseng and underground part of ginseng were examined. In addition, the physiological stress such as the leaf discoloration, rusty root and root rot as well as the resistance against the disease were examined. It was found out that as for the aerial parts of 3-years-old ginseng in test line, Eumseong 16 and 17 were better in the growth than the control lines were while in 4 years old ginseng, Eumseong 13 and 14 were better in the growth than Gumpoong as the control line was. As for the root weight of the 4-years-old ginseng for the underground part, there was no significant difference compared with control line while in 3-years-old ginseng, Eumseong 16 and 17 were heavier. The leaf discoloration did not happen to both 3 and 4-years-old ginseng. As for the root rot, 3-years-old Eumseong 16 and 17 suffered less root rot in the same way as for the control line. 4-years-old Eumseong 14 and 15 had less root rot in the same way as for the control line. 3-years-old Eumseong 16 and 17 have less rusty root in the same way as the control line while as for 4-years-old ginseng, Eumseong 13, 14 and 15 showed a lot of rusty roots in the same way as the control line. Conclusion : Finally, considering the growth characteristics, physiological stress and root rusty of the aerial parts and underground parts of the ginseng, we selected Eumseong 16 and 17 as the excellent lines for 3-years-old ginseng.

Background : The cultivation method of ginseng (Panax ginseng C. A. Meyer) has been introduced not only in the existing shading facilities but also in the cultivation method using the rain shelter house. In addition, direct seedling cultivation of ginseng is increasing in order to save labor. Ginseng cultivation area in the northern area is increasing with the disappearance of first planted field. Proper shading method in the northern ares is needed to grow direct grown ginseng using rain forest house. Methods and Results : Shading method using rain shelter house was Polyethylene film with layered polyethylene net 75%, blue-white duplicated PE film 85%, blue-white duplicated PE film 90%. Plant materials is 5-years-old Ginseng using direct seedling cultivation. In order to select proper shading materials of the rain shelter house in northern area, we investigated photosynthetic properties and growth of 5-years-old ginseng in rain shelter house. The temperature and humidity were slightly different between the traditional conventional shade facility and the rain shelter house, but the light intensity of the shading facility tended to decrease with the passage of time. The difference in shading method in rain shelter house was the highest at polyethylene film with layered polyethylene net 75%. As a result of the growth characteristics of the top part, 90% of blue-green double-sided film showed the greatest growth with 89.8 ± 1.5. The difference in top part between rain shelter house and shading facility is about 23 ㎝. Conclusion : Although the above growth characteristics of the ginseng shows this tendency, the root growth characteristics of the ginseng must be further observed.

Background : Ginseng (Panax ginseng C. A. Meyer) is a multi-year-cultivated plant that causes many insects and disease damage during the growing season. The Ginseng Rain-sheltered Shade House is one of the efficient cultivation techniques as reducing the damages caused by natural disaster such as blight, high temperature & humidity, dry, and heavy rain & snow. This study was conducted to investigate the growth characteristics of 4-years-old ginseng using rain-sheltered shade house suitable shading materials for the Gyeongsangbuk-do. Methods and Results : The rain-sheltered shade house shading materials were PE film with layered polyethylene net 90%, Light diffusion film with layered polyethylene net 75%, blue-white duplicated film. In order to determine proper shading materials of the rain-sheltered shade house, ginseng growth characteristics such as plant length, stem diameter, leaf length, root length and root diameter were investigated at 4-years-old ginseng. As a result, the evaluations of aerial part growth by measurements were good in the following order: PE film + polyethylene net 90%, Blue-white duplicated film and light diffusion film + polyethylene net 75%. The evaluations of root weight by measurements were heavy in the following order: Blue-white duplicated film, PE film + polyethylene net 90% and light diffusion film + polyethylene net 75%. The net photosynthetic rate was higher in blue-white duplicated film than other shading materials treatments during growth season including summer high-temperature period. Conclusion : In the 4-years-old ginseng cultivation in Gyeongsangbuk-do using the rain-sheltered shade house, aerial part growth in PE film + polyethylene net 90% was better than other shading materials. In addition, root weight in Blue-white duplicated film was heavier than other shading materials. It will be possible to know which shading material is the most suitable for Gyeongsangbuk-do area after further growth.

Background : The insufficient soil moisture due to spring drought causes the germination rate of ginseng seeds to be remarkably lowered and the low seeding depth causes the roots not to be settled but remain in the surface soil containing moisture, resulting in the ill-shaped ginseng. Especially, in the case of paddy soil, the soil environment is often over-humidified or over-dried, resulting in high rate of occurrence of physiological disorders such as rough skin, yellow-colored root and red-colored root, etc. compared to the upland soil, requiring more care in managing the soil. Therefore, this study was conducted with the aim to investigate the effects of stamping treatment on the direct seeding cultivation in the paddy soil and to investigate the survival and growth characteristics according to the seeding method. Methods and Results : We investigated the effects of stamping on the emergency rate and growth by using rollers (15, 20, 25, 30 ㎏), and also investigated the growth characteristics according to the direct sowing methods (broadcast planting, motorized seeder, semi-automatic seeder, manual seeder, hoop-type seeder). In the emergency rate of 1-year-old ginseng group directly sowing and treated with trampling, the group treated with 25 ㎏ & 30 ㎏ showed the highest emergency rate & growth, and above-ground & underground parts growth of 1-year-old ginseng by sowing method, there was no significant difference between sowing methods, the emergency rate of motorized seeder and semi-automatic seeder was high. Conclusion : In the paddy soils, the 25 – 30 ㎏ stamping after direct seeding showed superior above-ground growth and emergency rate, and there was no significant difference in growth, but motorized seeder and semi-automatic seeder had a higher rate of emergency in 1-year-old ginseng.

Background : Currently sprout ginsengs are produced in extensive variations of cultivation times, methods and specifications that are different in each farm in Korea. Also, regardless the effective ingredient content of ginseng, overgrown sprout ginseng are distributed so that the quality standardization of sprout ginseng is urgently required. The sprout ginseng market is only a segment of the Korean ginseng market still. However, If development of processed products utilizing the functionalities is connected, the market may exponentially grow. Also, if the use of sprout ginseng is extended to productions of drinks, cosmetics, facial masks and others in the cosmetics and health functional food industries, the export competitiveness to the global market is expected to increase. Therefore, this study aims the quality standardization of sprout ginseng to secure the market competitiveness in Korea and overseas by examining the property change following the cultivation period. Methods and Results : Growth of sprout ginseng were investigated on 20 th, 30 th, 40 th and 50 th days after planting on May 30 th. Growth of above-ground parts and underground parts of 2-years-old sprout ginseng increased with longer growing period. As the growing period became longer, the sprout ginseng weight increased, that is the result of the increase of the above-ground part. Also, according to the examination on the leaves, stems and roots properties of 2-year grown sprout ginseng in each growing period, a trend that, as the growing period is longer from 20 days to 50 days, the hardness, gumminess, chewingness and fracture of leaf, stem and root are higher. Conclusion : In case of cultivating sprout ginseng in a green house, as the growth period of 2-years-old sprout ginseng was prolonged, the growth of above-ground parts and underground parts was improved. And, as the growing period of sprout ginseng was prolonged, the properties of leaves, stems and roots tended to increase.

Background : This study was conducted to investigate the seedling, growth, and yield characteristics of 1-year-old Polygala tenuifolia by cultivation of different regions. Methods and Results : After growing the seedlings for 2 months in the greenhouse, they were planted at different altitudes including: 100 m or less (Cheongju), 250 m (negative), 300 m (Jecheon), and 500 m (Pyeongchang) in the first week of May. The flowering period, fertilization period, fruit weight, growth, and yield were recorded and investigated in that period. Results of analyzing the physicochemical properties of the soils revealed that the pH of the soil was close to neutrality of 6.7 - 7.3 at 100 m, 250 m, and 500 m altitudes and an acidity of pH 5.7 at 300 m altitude. The average temperature for different time periods and altitudes are the following: 3.8℃ from June to October during the harvesting season, 21.8℃ at 100 m altitude in the end of June, 10.8℃ at 500 m altitude in the middle of harvest period, and 2.7℃ higher at 100 m altitude than 500 m altitude. The difference in the number of rooting (between 11 and 12/㎡) and the rate of rooting (82 - 92%) was not significant. The plant length was 25 - 26.5 ㎝ at 300 m and 500 m altitude. The largest number of branch was at 1.8 with 250 m altitude and largest stalk diameter at 500 m altitude at 6.0 ㎜. Leaf length and leaf width were the same per area, but the branches were the largest at 500 m at 17.9. Dry weight of 12.7 g was heaviest at 500 m altitude implying that the higher the altitude, the higher the dry weight will be. Moreover, in the 500 m altitude, root length of 29.2 ㎝ was the longest, root diameter was 5.9 ㎜, and the dry root weight of 7.9 g was the heaviest. However, the number of supporting root was 4.9 - 7.3 which was not statistically significant. The optimal yield per 10 a was 94 ㎏ at 500 m altitude. This was very high compared to yield of 28 ㎏ at 100 m altitude. The seed weight per 10 a was 1.5 ㎏ and 2.3 ㎏ at 100 m and 300 m altitude, respectively. The highest content of Teuifolin contained in the root was 124.07 ppm at 500 m altitude. Conclusion : Results showed that 1-year-old P. tenuifolia had optimal growth, higher yield and better vital component content at altitude of 500 m.
