  • Neutinamu Library in Suji, Yongin, has been serving as a hub for local communities since its opening in 2000. In 2003, Neutinamu Library Foundation was established for the development of library culture, continuing the wave of the library movement in the third sector and carrying out cooperative projects with various institutions. Through these exchanges and activities, numerous records and materials were produced and collected at the library. In 2012 and 2013, Neutinamu Library Archive was built so that the records that have been collected could be utilized. As such, this article will introduce and discuss the processes in the creation and management of Neutinamu Library Archive.

  • This study was carried out to clarify the biologies and morphological characteristics of Rhynchaenus sanguinipes. Also some chemicals were tested to screen the effective insecticide for the control of the species. Up to date, Zelkova serrata has been hewn as host plant of Rhynchaenus sanguinipes, which shows serious damage in this country. In the present study, Ulmus pumila was first found as host plant in this study. Body lengths of larvae, pupa and adult were 4.53$\pm$0.30 mm, 3.30$\pm$0.42 mm and 2.96$\pm$0.12 mm, respectively. The overwintered adult of the species emerged on early April to late April, and adult of nekt generation emerged on early May to late May, Pupal periods were 10, 7.2, 5.1 and 4 days on 16, 20, 24 and 28$^{\circ}C$, respectively. The lower developmental threshold temperature was 5.8$^{\circ}C$. Four braconid parasitoids were found as natural enemies, which emerged mainly on late April to early June. Insecticidal activities with treatments of fenitrothion 50% EC, indoxacarb 30% WG, ethofenprox 20% EC and thiacloprid 10% SC was investigated against adult of R. sanguinpes, and they showed >90% mortality.

  • 세월이 흔들림에 잊혀져 가는 것이 너무 많은데, 부질없는 욕심은 자꾸만 자라 가는데, 해는 졌는데 별은 보이지 않고 내 가슴속에 깊은 정을 품고, 남몰래 숨어들어 몸을 맡기면 나만의 공간을 만들어 주면서, 귓가에 살포시 속삭이는 말, 녀석 너 아빠도 어릴 때 내 곁에 와서 뒷집 순이와 첫사랑 고백과 첫 키스의 황홀한 추억을 만들었단다. 마을 마다 파수꾼으로 조상님들의 추억을 혼자만 알고 있는 느티나무는 우리나라 전국에서 자생하는 낙엽활엽교목으로 배수가 잘되고 유기질이 많은 사질양토에서 잘자라며 넓은 공간이 많으면 생육에 적합한 수종으로 장수목(長壽木)이다. 느티나무는 마을의 정자목으로 공원과 가로수에 적당한 나무로 예로부터 우리의 사랑을 많이 받고 있다. 이런 나무에 피해를 주는 몇몇 해충종에 대해서 생태 및 방제법을 소개하고자 한다

  • This paper investigated the combustion properties of the Pinus rigida, Castanea sativa, and Zelkova serrata which are grown in Korea using the cone calorimeter. The heat release rate and smoke production for these species were measured. With respect to an increase of retardant properties attributed to char formation, Zelkova serrata showed good properties compared with that of Pinus rigida and Castanea sativa. The Castanea sativa has high $CO_{peak}$ Yield and high $CO/CO_2$ Yield compared with that of Pinus rigida and Zelkova serrata.

  • Wood has an essential drawback such as high combustion ability. The purpose of this paper is to examine the combustion properties of the quercus variabilis and zelkova serrata dried at room temperature. The cone calorimeter (ISO 5660-1) was used to determine the heat release rate (HRR) and fire smoke index, as well as CO/$CO_2$ production and smoke obscuration. The total heat release (THR), $140.2\;MJ/m^2$ of the quercus variabilis under an external $50\;kW/m^2$ was high in comparison with THR $85.7\;MJ/m^2$ for the zelkova serrata. Furthermore, the quercus variabilis has high total smoke production (TSP), $3.50\;m^2$ compared with TSP $0.65\;m^2$ of zelkova serrata. Thease results depend on the bulk density of tested wood species. In addition, the CO/$CO_2$ production ratio of zelkova serrata and quercus variabilis was measured as 0.053, 0.043, respectively. Also, zelkova serrata showed an increase of fire-resistance attributed to char formation compared with that of quercus variabilis.

  • 느티나무는 우리나라 전국에 조림 가능한 향토수종으로 앞으로 산림의 다목적 기능에 부응하기 위하여 시대적으로 많은 조림이 요구되는 수종이다. 느티나무는 심근성이며 내음성은 강하나 건조에 약하여 조림적지는 입지에 대한 요구도가 높기 때문에 계곡, 산록, 마을주변의 배수가 잘되고 통기성이 양호한 곳에 식재하여야 한다. 유시생장이 신속한 속성 활엽수로써 용도가 다양한 고급용재 조림수종이다.

  • The purpose of this study was to identify the species of the woods used in the main building (Daewoongjeon) of Bulgapsa temple in YeongGwang. Eighty eight woods sampled were divided into four parts; pillars(21), rafters(19), purlins(16) and other wood elements(12). Four species were identified; Pinus spp. (hard pines; diploxylon), Abies spp., Quercus spp. and Zelkova serrata Makino. Pillars and corner-angle rafters were mainly Zelkova; however, other wood elements were mostly Pinus spp. The high ratio of Zelkova in this building would be ascribed to the preference of this species to pines owing to its superior quality before the late Chosun Dynasty.

  • The purpose of this study is to examine the species of wooden members used in the Youngsanjeon Hall of the Sucknamsa temple in Anseong, Korea. Ninety-five wood samples from pillars, head-penetrating ties, beams, corner rafter, rafter, floor board and other wood members were identified. Seven species identified were hard pine, exotic pine, Zelkova serrata, Ginkgo biloba, Diospyros, Quercus(Cerrus) and Pyrus spp. In the case of pillars, eight were hard pines and the others Zelkova and Pyrus. Species of angle rafter were Ginkgo biloba and Zelkova. and those of beams were one hard pine and one Zelkova. Two purlin samples were Quercus(Cerrus) and rafters were hard pines except one Ginkgo and one exotic pine. Roof-filling timbers were identified as Zelkova and Diospyros spp. The other samples of roof-filling timbers were all identified as hard pines. The use of Ginkgo and several hardwoods in addition to hard pines may indicate supply of local logs near the Sucknamsa temple.

  • In this study cadalene, which is classified into sesquiterpenes constructed with 15 carbons of naphthalene skeleton, was isolated from ethanol extracts of Zelkova wood (Zelkova serrata) using successive silica gel column chromatography. The purified cadalene compound was subjected to structural analysis using HPLC, EI-MS and $^1H$, $^{13}C-NMR$. Its molecular weight was measured to 244 (m/z) and methyl and isopropyl group were attached at C1 and C4 position, as well as hydroxyl group at C7 and methoxyl group at C3 in the naphthalene skeleton, respectively. Yield of 7-hydroxy-3-methoxycadalene amounts to 0.03% based on air dried Zelkova wood powder. It was distributed only in xylem tissues(only in heartwood) of Zelkova wood, not in leaves and bark.

  • This study was conducted to examine the effectiveness of various dressing materials applied to tree wounds in Korea. Significantly higher wound closure rates than those of controls were found when thiophanatemethyl paste (Topsin Paste$^{(R)}$) was applied to Ginkgo biloba, Zelkova serrata, and Prunus yedoensis; lanolin to Z. serrata and P. yedoensis; and tebuconazole paste (Silvacur$^{(R)}$) to P. yedoensis. However, significantly lower wound closure rates than those of controls were found when petroleum jelly (Vaseline$^{(R)}$) was applied to G. biloba, Z. serrata, and P. yedoensis. It was noted that the wounds of Z. serrata and P. yedoensis treated with petroleum jelly expanded due to the death of cambium located at the edge of the wounds. Wound closure rates applied with adhesive - non-toxic to human body (Okong bond$^{(R)}$) were also significantly lower than those of controls in Z. serrata. Pinus densiflora showed no reaction to any experimental wound dressing because of resin secreted from the exposed cambium.
