Bamboo is one of the most abundant biomass resources, which has advantages, such as short growth cycle, lightweight, and good mechanical property. As a renewable raw material, bamboo has been widely used in furniture, construction, and decoration. However, bamboo has some inherent drawbacks, like dimensional instability, hydrophilic property, and low resistance to biological factors (fungi, and insects), which greatly shortens its service life. For these reason, many efforts have been devoted to modifying bamboo to improve its properties and durability. Among a variety of bamboo species, Phyllostachys bambusoides (giant bamboo), Phyllostachys nigra (henon bamboo) and Phyllostachys pubesens (moso bamboo) are widely grown in Gyeongsang- and Jeolla-do, which are provinces of southern regions in South Korea. Despite the value of bamboo resources, bamboo forests in the country have been left unmanaged and neglected. The bamboo-related industry is gradually declining due to the increase in use of various materials along with changes in economic and social conditions. Heat treatment is considered to be one of the most effective approaches to improve drawbacks of bamboo materials, so it shows a great potential application in treating bamboo materials in the industry. In this study, moso bamboo (with a diameter over 10 cm) was subjected to heat treatment to improve its properties. Heat treatment was performed step by step in a large drying chamber as follows; pretreatment, cooking (100℃), steaming (140℃), and cooling during 4 days. After heat treatment, the changes in the chemical properties as well as microscopic structures of moso bamboo were analyzed. To evaluate the durability of heat-treated moso bamboo, fungal decay resistance, termite resistance, and artificial UV weathering test were also conducted. As a result of developing heat-treatment technology, mass production of dried moso bamboo (MC4%) is possible. Also, it was confirmed that there is no cracking on bamboo surfaces and durability is significantly improved. It is thought that these results can be used as an important data for better development of new uses of bamboo resources.

This study was carried out to determine the suitability of 3 months old bamboo species of Phyllostachys bambusoides S. et Z., Phyllostachys Pubescens Mazel and Phyllostachys nigra var henonis Stapf as raw materials for the manufacture of strandboard. Total of 108 strandboards were made using urea-formaldehyde resin content level of 12% and one percent of liquid wax emulsion. The strandboard consisted of three layers the top and the bottom layer of which were oriented to the same direction and weighted 25% of the strandboard each. The middle core layer weighed 50% of the board and was perpendicular to the outer top and bottom layers. Analysis was performed to determine the effect of strand lengths and Uowing years of 3 months, 2 years and 3 years on strandboard properties. The physical and mechanical properties of bamboo species and boards were measured and compared to the standard requirements of strandboards. The results are as follows; 1. The more the growing years the higher the density of bamboo. Top part of bamboo indicated higher density value than that of bottom part. 2. Bamboo showed higher static bending strength compared to the main wood species. Longer growing years of bamboo generally inclosed the static tending strength out there were no statistical significancies for Phyllostachys bmbusoides S. et Z. and Phyllostachys pubescens Mazel. 3. Strand length indicated no difference on density and moisture content of strandboard. 5 cm of strand length gave the best static bending strength and internal bonding strength. Bamboo strandboard exhibited lesser extents of thickness swelling than that of CSA standard. 4. 3 months old bamboo gave higher static bending strength of strandboard than those of 2 years and 3 years old bamboo. In case of Phyllostachys nigra var henonis Stapf, 3 months old bamboo indicated higher internal bonding strength than those of 2 years and 3years old bamboo. but in Phyllostachys bambusoides S. et Z., Phyllostachys pubescens Mazel, there were no difference among growing years. Growing years showed no different physical properties of bamboo strandboard.

The Lao PDR is a developing country that heavily relies on rice farming. During off-season of rice farming, rural villagers produce non-timber forest products such as bamboo products. Until recently many villages have overexploited bamboo resources and supplied raw bamboo materials to foreign companies. Although the Lao government allocated harvesting quotas, most villagers keep on cutting bamboos due to no other income during the off-season. This study provides an alternative income model, bamboo handicraft, that can increase villagers’ income while minimizing the use of bamboo resources. It also accesses the economic feasibility of the new income model for a mountain village, Nongboua village, where surveys were conducted on general incomes of 10 sample families who participated in the new income model voluntarily. A difference was made during the off-season when the sample families worked on cutting bamboos (previous income) or bamboo handicrafts (new income). A daily wage of $ 11.5 was used for the previous income, based on our surveys. For the new income, it was assumed that single family could produce 6 bamboo handicrafts daily with a unit price of $ 2.3, resulting in a daily income of $ 13.8. During the off-season, 8 and 14 working days in a month were assumed for the previous and new incomes based on surveys. Then the previous previous and new yearly incomes were estimated and compared using normality and paired t-tests. This study found that the new yearly income was significantly greater than the previous yearly income (p < 0.001): the former (rice farming and bamboo handicraft, $ 2,064) was 42% ($ 608) greater than the latter (rice farming and bamboo cutting, $ 1,456). These results suggested that the new income model could increase villagers’ income significantly. If the bamboo handicraft model is applied for other areas with bamboo resources, it can provide an opportunity to improve the rural economies and livelihoods of developing countries. 본 연구는 라오스 산촌마을의 기초 소득을 조사·분석하여, 지속가능한 대나무 자원을 활용한 새로운 소득 모델의 효과성을 제시하고자 하였다. 연구 대상지는 비엔티안 캐피털 주의쌍통군 농부아 마을로써 산림과 벼농사지역이 혼재된 자급자족형 논농사 위주의 마을이다. 농부아 마을은 과일, 야채 등 상업적 영농활동은 전무하여, 단순한 소득체계를 가지고 있다. 우기(6월~11월)는 천수답 벼 농사에 의존하고 있고, 건기(12월~5월)는 가축 판매 또는 대나무 벌채를 통한 수익체계로, 2018년 농부아 마을의 기존 소득은 평균 1,456 달러로 분석되었다. 라오스 1인당 GDP (2018)가 2,690 달러와 비교할 때, 농산촌 지역의 소득은GDP의 약 절반가량 수준 이다. 쌍통군 지역의 대나무 수종은 젓가락, 이쑤시개 등 원자재로서 베트남 가공회사로 판매되고 있다. 가공회사는 수익을 위해 수요량에 따라 마을 주민을 고용하여 다량의 대나무를 벌채하고 있다. 이러한 대나무벌채는 빠르고 수익성은 있지만, 회사 수요(농한기 한정)에 따라 비정기적으로 마을주민을 고용(하루 고용비용 $ 11; 고용시간 8시간)하며 노동 강도가 높다. 또한 대나무 자원의 지속가능한 이용에도 한계가 있다. 이러한 조건에서 마을주민의 대나무 단순벌채로 인한 연 소득은$ 552로 분석되었다. 소규모 마을 주민을 대상으로 대나무를 이용한 지역상품을개발·생산하여 기술전수 및 판매를 시범적으로 실시하였다. 대나무 벌채와 비교하여 적은 양의 대나무를 이용하여 고부가가치를 창출할 수 있으며, 노동 강도가 높지 않아서 여가시간에작업공정이 가능하다. 표본 10 가구의 생산량은 초기단계에서하루 최대 6개가 생산가능하며, 제품 단위가격을 $ 2.3로 책정할 때, 연 소득은 $ 1,160 으로 분석되었다. 기존 모델의 소득(농업+대나무 벌채)은 평균 $ 1,456이며, 신규모델의 소득(농업+대나무 공예품)은 평균 $ 2,064로 신규소득이 $ 608 높게 나타났다. 기존소득과 신규소득의 농업 수입이 동일한 조건이므로, 소득에 차이를 주는 요인은 대나무수입으로 신규 소득의 평균 $ 2,064가 기존 소득인 $ 1,456 보다 약 42% 증가된 수치로 나타났다.

Bamboo is one of the major biomass resources that have many advantages compared to wood due to its fast growth, short cycle, and a relatively cheaper in price. In this study, the anatomical characteristics as cell dimension and crystalline properties of four bamboo species that are using widely in Indonesia, namely, Giant (Dendrocalamus giganteus), Kuning (Bambusa vulgaris), Betung (Dendrocalamus asper) and Tali (Gigantochloa apus) bamboos were examined by optical and scanning electron microscopy and an X-ray diffraction method. The observation of anatomical characteristics in cross section showed that Giant and Tali bamboos had vascular bundle type Ⅲ, while Kuning and Betung bamboos had vascular bundle type Ⅳ (Grosser and Liese , 1971). The inner part of vascular bundles in four bamboo species showed clear boundaries between central vascular strand and fiber strand, while the outer part samples showed unclear boundaries. The fiber length in outer part samples of the four bamboo species showed higher dimension than that of the inner part samples. In addition, the results showed a significant difference among the four bamboo species, showing the longest fiber length in Betung bamboo. Giant bamboo showed the greatest vessel and parenchyma diameters. Parenchyma cells in Betung bamboo showed the greatest length and width in both radial and tangential sections. The analysis of variances on vessel diameter and parenchyma diameter revealed significant differences among the four bamboo species. The relative crystallinity and crystallite width in outer part samples of the four bamboo species showed higher values than the inner part samples, with the highest values obtained from Tali bamboo.

원시 어법 ‘죽방렴’ 관련 어휘 연구 2 - 죽방렴 어업 행위, 어획물 처리 관련 어휘 -

홍기옥 영남대학교 인문과학연구소 2019 人文硏究 Vol.- No.86

Bamboo screen is one of the traditional Korean language, and it is a way to catch the fish by using the difference of the tide interval by walking the bamboo feet in the shallow water depth where the meat is frequent. It is a trap that catches the fish that come along the tide by walking the foot of the bamboo in the V shape and the oak which exceeds 5 meters in the sea, and it returns it to the ebb tide. The history of bamboo screen can be found in the “Bamboo screen” in the Joseon Dynasty, which is the same way as the bamboo screen of the present day. It is a fishery type used in coastal waters such as Samcheonpo, Namhae-gun. This study collected and summarized relevant vocabularies of bamboo bamboo in Samdong-myeon area, Namhae-gun, Gyeongsangnam-do. The bamboo-related vocabulary survey was divided into two parts: an investigation of documents containing relevant vocabulary and a field survey of actual bamboo fishery area. The bamboo-related vocabulary were investigated based on bamboo-related names and bamboo-based fishery processes. In addition, bamboo-related vocabularies used in real life were collected and summarized in Samdong-myeon, gyungnam, including idiomatic expressions related to bamboo fishery activities. 본 연구는 문헌상으로 조선시대부터 내려오는 전통 어법으로 확인할 수 있는 ‘죽방렴’에 관련된 어휘를 문헌, 현장 조사를 통해 수집, 정리하는 것이 목적이다. 조수간만의 차이를 이용하여 남해안에서 주로 행해졌던 원시 어 법(漁法)인 ‘죽방렴’에 관련된 어휘를 목록화하고 관련 데이터베이스(DB)를 구축하여, 어촌지역의 어법(漁法)과 관련된 어휘장을 구축하기 위한 기초 작업으로 볼 수 있다. 원시 전통어법인 돌살, 죽방렴을 이용한 어로가 일부 지역에서 노년층을 중심으로 그 명맥이 유지되어 오고 있지만, 어업방식의 현대화로 돌살, 죽방렴과 같은 전통 어법의 미래는 불투명할 수밖에 없다. 따라서 이와 관련된 어휘를 조사, 정리하여 데이터베이스화 하는 작업은 어로방식, 관련 문화를 보존하기 위해 필요하며, 의미 있는 일이다. 관련 어휘 조사는 현재도 죽방렴을 이용한 어로가 행해지고 있 는 경상남도 남해군 삼동면 지역을 중심으로, 지역 관공서의 추천을 받아 죽방렴을 소유하고 관련 어로를 3대째 하고 있는 제보자들을 정하여 진행하였다. 어휘 조사의 전체 범주는 ‘죽방렴 관련 명칭, 죽방렴 만들기와 어업행위, 보수하기, 어획물 처리, 고사 지내기, 관용표현’ 등으로 나누어 관련 어휘를 조사, 정리하였다. 조사를 통해 ‘죽방렴’에 관련된 222개 어휘를 수집하였고, 이 중 180개는 『표준국어대사전』이나 <한민족언어정보화 방언검색기>에 수록되지 않은 어형으로 죽방렴 관련 연구에서 발굴되지 않은 어형도 있었다. 또한 현지에서 사용하는 죽방렴 관련 연어 구조의 어형도 수집, 정리하였다. 이를 통해 원시 전통어법인 죽방렴 관련 어휘장을 정리할 수 있는 기초 작업이 되었으면 한다.

Bamboo was a personified literati-scholars and the symbol of figuring virtue with things of Confucian society. Therefore many literati and calligraphers tried to build up their character while they drew bamboo as a material of the study of things and nature. especially, windy bamboo painting added metaphysical aesthetics was a personified literati-scholar that symbolize the overcoming the pain, hardship, and integrity. For a long time literati and calligraphers have been drawing bamboo to build up their character. However there has been a few painters who completed high aesthetic world with his windy bamboo. Gamg-am’s windy bamboo paintings have embodied various aesthetic feelings. His windy bamboo paintings based on the beauty of strongness to express the spirit of literati-scholar. He formed his own aesthetic world that calligraphy and painting harmonize with each other by how to use Chinese ink to express being dark and light, harmony and spreading. Therefore his windy bamboo paintings are the whole bamboo painting based on the windy bamboo painting that Tan-eun, Jeong Lee has established in Josun dynasty. This embodied a new style of windy bamboo painting aesthetics based on the beauty of strongness. His windy bamboo painting embodied the aesthetics of Confucian society and symbolize the personified spirit of literati. He formed his own unique aesthetic world that emphasize the human’s mind and beauty of strongness in the whole bamboo in the windy bamboo painting history. His aesthetics was enlarged to the thought of passion and being strange. This stemmed from the beauty of clearness based on Sung Confucianism (Juja) and the beauty of passion based on philosophy of Wang Yangming and embodied as harmony between being neatly in appearance and being comfortable inside. So Gang-am``s windy bamboo painting has embodied the unique Korean style of literati-scholar``s painting.

The present study was designed to explore the antioxidant effect of Bamboo powder and its immunoreactivity in pigs. We investigated the functional properties of Bamboo extracts by means of measuring the contents of total polyphenols and flavonoid as well as determining ABST, DPPH radical scavenging activity, and hydroxyl radical scavenging activity and anticancer activity. The total phenolic compound and flavonoids contents of Bamboo extracts were 171.25 mg/g and 127.5 mg/g, respectively. The DPPH radical, hydroxyl radical, ABST radical scavenging activity of Bamboo extracts were 17.3%, 12.5% and 21.5%, respectively. Evidenced by MTT and cell cycle assay, Bamboo dose-dependently inhibited the cell proliferation and induced G0/G1-phase arrest in CHO cells at concentrations of 100, 250, and 500 μg/ml Bamboo extracts. More than 80% of apoptotic cells were observed by staining with annexin V in 500 μg/ml Bamboo-treated CHO cells, indicating that Bamboo had potent anticancer activities. Next, to investigate the effect of Bamboo on cytokine, immunoglobulin concentration, and blood compositions, flatting pigs were fed with Bamboo powder for 38 days. Flatting pigs were divided into 4 groups; basal diet (control), basal diet supplemented with 1% Bamboo powder (T1), 2% Bamboo powder (T2), and 3% Bamboo powder (T3). The level of hemoglobin increased in the all Bamboo-fed groups compared with the normal control group. In particular, platelet levels in the all Bamboo-treated groups increased by approximately 90% compared with the levels from pig on a normal control. Serum levels of immunoglobulins (IgG, IgA) in the pigs fed Bamboo powder were modestly increased, and the interferon-γ level also was strongly increased in 2% or 3% Bamboo-fed groups compared with the levels in control groups. Together, these results demonstrated that Bamboo extracts had an effective capacity of scavenging for ABTS, DPPH, and hydroxyl radicals and showed correlation with potent phenol and flavonoid contents, thus suggesting its antioxidant potential. Moreover, administration of Bamboo in 2∼3% improved blood parameters and platelets, and especially immunity-related ones such as IgG, IgA, and interferon- γ, leading to be potential feed additives in flatting pigs.

Experimental study on improving bamboo concrete bond strength

Mali, Pankaj R.,Datta, Debarati Techno-Press 2019 Advances in concrete construction Vol.7 No.3

Bamboo concrete bond behaviour is investigated through pullout test in this work. The bamboo strip to be used as reinforcement inside concrete is first treated with chemical adhesive to make the bamboo surface impermeable. Various surface coatings are explored to understand their water repellant properties. The chemical action at the bamboo concrete interface is studied through different chemical coatings, sand blasting, and steel wire wrapping treatment. Whereas mechanical action at the bamboo concrete interface is studied by developing mechanical interlock. The result of pullout tests revealed a unique combination of surface treatment and grooved bamboo profile. This combination of surface treatment and a grooved bamboo profile together enhances the strength of bond. Performance of a newly developed grooved bamboo strip is verified against equivalent plain rectangular bamboo strip. The test results show that the proposed grooved bamboo reinforcement, when treated, shows highest bond strength compared to treated plain, untreated plain and untreated grooved bamboo reinforcement. Also, it is observed that bond strength is majorly influenced by the type of surface treatment, size and spacing of groove. The changes in bamboo-concrete bond behavior are observed during the experimentation.

1900년대 대구 화단 죽석화(竹石畵) 연구

이인숙 ( In Suk Lee ) 경북대학교 영남문화연구원 2012 嶺南學 Vol.0 No.22

Painting the Four Gracious Plants(Sagunja) became a widespread area in the late of Chosun and Modern period. While western ``art`` occupied the general trend instead of the ``paintings and calligraphic works(書畵)``, the Four Gracious Plants painting was prevalent consistently in Daegu. In this study, bamboo-stone paintings among the China-ink paintings that depicts bamboos(墨竹畵) out of the Four Gracious Plants were particularly preferred, and focused on the fact that it formed a regional characteristics. The Four Gracious Plants painting in Daegu starts from Seok-jae Seo Byeong-o(石齋 徐丙五, 1862~1936), who worked on the poems, paintings and calligraphic works. Seo Byeong-o kept company with Puhua(蒲華, 1830~1911) during his trip to China and absorbed his style of painting, broad-minded it and formed ``Seok-jae bamboo(石齋竹)`` style which was full of warmth. Seo Byeong-o enjoyed painting bamboo-stone paintings(竹石?), and his paintings can largely be divided into two, ``Double-pole-shaped stone(石上雙竿形)`` and ``Bamboo-stone concatenation shape(竹石竝置 形)``. The unfolded aspects of how these two kinds of paintings had an effect on each other from 1920 till 1990 were searched through the works of bamboo-stone painters in Daegu. ``Double-pole-shaped stone(石上雙竿形)`` is a unique painting style which appears in the bamboo-stone paintings of Puhua, and it is understood as an implementation of Su Shi`s(蘇軾, 1037~1101) bamboo painting style that is recorded by Mi Fu(米?, 1051~1107). Seo Byeong-o brought the Double-pole-shaped bamboo-stone painting to Daegu, which he received as a present directly from Puhua, and this painting style took root by the painters such as Seo Byeong-o, Kim Jin-man, Bae Hyo-won, Seo Sang-ha in Daegu. Since then, from 1950s till 1970s these two bamboo-stone painting styles were passed down to Seo Dong-gyun, Park Geun-sul, Seo Geun-seop. In 1980s, the bamboo-stone paintings were painted in various ways by the painters who were members of Yeong-nam-Seo-hwawon(嶺南書畵院), led by Seo Geon-seop after Seo Dong-gyun. In 1990s, by the painters from Cheon-gang-chi-mook-hoi(千江醉墨會), mainly led by Park Geun-sul, various bamboo-stone paintings were appeared, in which the bamboo and the stone were interpreted in a drastic and fresh way. In 1900s, for almost 100 years, bamboo-stone paintings were painted as a representing painting style among the Four Gracious Plants paintings in Daegu. The Four Gracious Plants painting in Daegu were chronicled from Seo Byeong-o, Seo Dong-gyun, Park Geun-sul to Seo Geun-seop, the painting impulse was kept and it is passed down to the fourth and fifth generation who are active in the present. The bamboo-stone paintings in Daegu is significant from the point of views that it prefers the tradition with the direct effect of the chronicle and it forms a background of regional sentiment aspiring the bamboo friends of stone(竹友石) out of the gracious plants(gunja 君子). 1900년대는 유화와 조각 등 ``미술``이 이식되고 주류적 흐름으로 전개되면서 기존의 ``서화``는 그 문화적 기반과 함께 퇴락한 시기이다. 그러나 大邱에서는 수채화, 양화 등과 함께 서예, 사군자화도 꾸준히 지속되었다. 근현대기 사군자화는 문명사적 전환의 소용돌이 속에서 ``군자``를 지향하는 주체의 내면을 투사함으로서 ``전통``의 쪽에 있던 계층의 정체성을 표상하는 완충의 역할을 수행하였다고 생각한다. 근현대기 대구 화단의 사군자화는 당대 흐름에 적응하지 못한 문화 지체라는 관점보다 이러한 현상이 표상 하는 내재된 의미성, 사회적 유용성, 지역적 특수성이 한국미술사의 전체상 속에서 해석되고 자리매김 되어야할 문제이다. 대나무에 바위를 함께 그린 竹石?가 지속적으로 그려진 것은 1900년대 대구 화단 묵죽의 한 특징이다. 그 시작은 시서화 삼절의 서화가인 石齋 徐丙五(1862~1936)이다. 서병오는 상해에서 교유한 蒲華(1830~1911)를 배워 ``石上雙竿形``과 ``竹石竝置形`` 죽석화를 그렸다. 석상쌍간형은 화면의 한 쪽 邊에 돌출한 바위 위로 두 개의 죽간이 솟아있는 특이한 도상으로 米? (1051~1107)이 기록한 蘇軾(1037~1101)의 묵죽법이 포화에 의해 구현된 도상으로 파악된다. 서병오는 포화에게 석상쌍간형 죽석화를 직접 선물 받아 대구로 가지고 왔고, 이 도상은 서병오를 비롯해 김진만, 배효원, 서상하 등에 의해 1900~40년대에 대구 화단에 정착되었다. 근대기에 유행한 석상쌍간형과 죽석병치형 죽석화는 1950~70년대에 서병오의 제자인 竹? 徐東均(1902~1978), 서동균의 제자인 千石 朴根述 (1937~1993)과 野丁 徐根燮(1946~) 등 대구 사군자화 2, 3세대 작가들에 의해 계승되었다. 이들은 각자의 개성에 따른 변화를 보여 서병오풍이 거의 답습되었던 앞 시기와 달랐다. 그런데 1980년대는 근대기 죽석화 도상이 다시 나타나는 복고적 경향을 보였고, 반면 1990년대는 대나무와 돌의 포치와 어울림을 풍죽으로 결합하는 경향이 나타났다. 1990년대 대구 화단 죽석화는 그 畵意인 ``竹友石``의 정신을 풍죽 형식을 통해 새로운 시각으로 표현하였다. 죽석화는 1900년대 대구 묵죽의 주요 도상으로 전개되었고 공모전 상위 입상작으로 선호되었다. 그 배경에는 사군자화의 ``전통`` 회화로서의 성격, 대나무와 바위가 상징하는 ``군자`` 정신, 이 둘이 서로 어울려 빚어내는 ``竹友石``의 畵意를 애호한 대구사람들의 정서가 내적 동력으로 작용하였다고 생각한다. 1900년대 대구 화단 죽석화는 대구의 지역적 특성과 밀접한 미술이다.

Human & Disaster: Analysis of the Actual Use of Northern Bamboo in Folk Remedies

Kisoo Oh,Changjun Kim,Hyangju Lee,Wonhyeon Lim J-INSTITUTE 2022 International Journal of Human & Disaster Vol.7 No.1

Purpose: Northern bamboo is an evergreen broad-leaved shrub. It reaches 1~2m in height and 3~6mm in diameter, spread throughout Korea. Northern bamboo leaves, also called bamboo leaves, have been used to treat children s convulsion, vomiting blood, and severe thirst in fever. Women with repressed anger illnesses boiled bamboo leaves covered with frost and drank the water. Therefore, this study investigated the folk remedies relat-ed to Northern bamboo. The researchers tried to analyze the studied data and examine the possibility of using northern bamboo as a multi-purpose natural health food. Method: This study investigated and analyzed the folk remedies related to northern bamboo at herbal medi-cine stores, herbal medicine pharmacies, and medicinal herb decocting shops in Daegu metropolitan city and Yeongcheon, Gyeongsangbuk-do. Researchers also searched and collected valuable materials in the Naver blog. This paper conducted a Frequency analysis on the collected data with several categories, such as the collecting season of bamboo, the usable parts of it, the processing ways of it, the ingestion types of it, and the frequency of its utilization by disease. Results: In analyzing the use of northern bamboo to folk remedies, cardiovascular disease was the most fre-quently used for each related disease. The frequency of use for cancer-related diseases, diabetes-related diseases was also high percentage. Bamboos were collected regardless of the season, but most were collected during the spring when new shoots were born. All bamboo parts were usable, but leaves were used the most. Bamboos were used in various processing ways, but ‘drying’ regardless of sunlight and shade was the most common method. As for the ingestion types, tea was the most common style. Conclusion: Northern bamboo has been used for various diseases in folk remedies, and it is easy to obtain be-cause it grows anywhere in the country. Eggplant seeds, jujube, licorice, and others are added when processing or ingestion, but in many cases, it is consumed alone without adding anything else. As a result of investigating and analyzing the folk remedies related to northern bamboo, the researchers reaffirmed the value of bamboo through this study. This paper evaluated that northern bamboo has the excellent potential to be used as a multi-purpose natural health food.
