        산주의 삼림투자 인식에 관한 연구 : 강원도지역을 중심으로

        서영완,최종천 강원대학교 삼림과학연구소 2000 Journal of Forest Science Vol.16 No.-

        일반산주와 임업후계자 · 독림가의 산림 투자 인식을 비교분석한 결과 다음과 같이 임 · 독림가가 일반산주보다 산림투자에 대하여 상대적으로 높은 관심을 보이고 있었다. 1.일반현황의 비교에서 임 · 독림가가 일반산주보다 교육수준과 월평균소득 면에서 높게 나왔으며, 직업의 경우 임 · 독립가는 다양한 직종에 종사하고 있는 반면 일반산주는 농업에 편중되어 있는 것으로 나타났다. 2.산림의 소유동기에서 임 · 독림가의 경우 일부상속 · 일부매입이 41.2%로 가장 많은 반면, 일반산주의 경우는 선대로부터의 상속이 40.9%로 가장 많았다. 3.산림투자에 대한 산주태도에서 임 · 독림가가 일반산주보다 과거 5년동안 산림투자 경험과 정부지원 신청경험 모두 높게 나타났다. 4.정부지원 제도에 대한 인식에서 일반산주보다 임 · 독림가가 정부지원 제도에 대하여 상대적으로 많이 알고 있는 것으로 나타났으며, 정부지원 제도의 실행상태에 대해서는 임 · 독림가와 일반산주 모두 '그저 그렇다'는 미온적인 반응을 가장 많이 보였다. The study is focused on comparing the perception of forest investment by two types of forest owners, ordinary forest owners (OFOs) and forestry successors and model forest owners(FSMFOs). The results show that FSMFOs' perception of forest investment is relatively high compared with OFOs' perception The details are as follows ; 1.In the general status, the education and income levels of FSMFOs are higher than those of OFOs, and FSMFOs are engaged in various kinds of jobs while OFOs are inclined to lean toward farming. 2.Of the motives to own forests, partial-purchase and -inheritance is the most of FSMFOs(41.2% ) and inheritance the most of OFOs (40.9% ) 3.The number of FSMFOs who had made forest investment and applied government support is more than that of OFOs. 4.FSMFOs know government support better than OFOs do, while both show lukewarmness on weather the support is carried out according to the rules. Key words : forest investment, forestry successor, government support

        측두 규격방사선사진 촬영시 두부의 위치변화가 확대율에 미치는 영향

        서영훈,최영철 대한소아치과학회 2001 大韓小兒齒科學會誌 Vol.28 No.1

        측두 규격방사선사진 촬영시 피사체의 정중시상면과 필름의 평행관계가 유지된 상태에서 피사체의 수직회전 그리고 피사체의 정중시상면과 필름의 평행이 이루어지지 않는 피사체의 수평회전에 따른 확대율의 변화를 평가하고자 하였다. 이를 위하여 수직회전 및 수평회전을 정밀하게 재현할 수 있는 입체적 기구를 제작하여 측두 규격방사선사진을 촬영한 후, 현상된 필름 상에서 선계측치 및 각도계측치에서의 확대율, 그리고 피사체의 정중시상면을 중심으로 한 좌우 대칭적인 해부학적 구조물 간의 거리차에 의한 확대율의 차이를 비교하였다. 그 결과,측두 규격방사선사진을 촬영시 피사체의 정중시상면과 필름의 평행관계가 유지된 상태에서 두부 고정장치의 양측귀꽂이를 중심축으로 한 수직회전은 모든 계측치의 확대율에 영향을 미치지 않으나, 정중시상면의 수평회전이 커질수록 수평 계측치에서는 대체로 확대율의 감소가 커지는 반면, 필름 우측의 수직계측치에서는 확대율의 점진적인 증가가, 좌측의 수직계측치에서는 확대율의 점진적인 감소가 나타나며, 동일한 회전량일 때 수직계측치에서보다 수평계측치에서 대체로 더 큰 차이가 나타나 측두 규격방사선사진의 촬영 시에는 피사체의 정중시상면과 필름과의 평행관계 유지의 중요성과 함께 피사체의 수평회전의 정도에 따른 필름의 부위별 확대율 변화의 유형을 숙지해야 할 것으로 가늠된다. This study was designed to evaluate the effects of angualtion changes of head posture on the enlargement ratios of a lateral headfilm depending on the vertical or horizontal rotation of the objects. A device was constructed to measure regional changes of enlargement ratios. The device was held within the cephalostat and cephalograms recorded at each measured degrees of the device tilting, vertically and horizontally. The enlargement ratios of the horizontal, vertical, and angular measurements on the films taken at each tilted angulations were obtained and compared with those on the films taken without rotation. In summary, the enlargement ratios of the horizontal linear measurements were decreased during horizontal rotations. The enlargement ratios of vertical measurements of the right side on the film were increased and those of the left side were decreased by the horizontal rotations. Enlargement ratios of horizontal measurements were affected further than those of vertical measurements by the same angular changes of the horizontal rotations. Therefore, a disruption of parallelism between the object's midsagittal plane and the film could result in distortion of the image while vertical rotation around the object's porionic axis would not significantly affect the enlargement ratios on the headfilm.

      • 강원,경북지역 낙엽송 지위지수 적합성 평가에 관한 연구

        이대성 ( Dae Sung Lee ),이의섭 ( Eui Sub Lee ),최종현 ( Jong Hyun Choi ),서영완 ( Yeong Wan Seo ),최정기 ( Jung Kee Choi1 ) 한국임학회 2014 산림과학 공동학술대회 논문집 Vol.2014 No.-

        본 연구는 강원 및 경북지역의 낙엽송 지위지수의 적합도를 평가하기 위해 실시되었다. 연구자료는 강원 및 경북지역의 45개 낙엽송 인공림 표준지 조사로부터 우세목 1본을 선발하여 수간석 해를 통해 분석되었다. 산림청에서 개발된 지위지수표에 의거하여 본 연구대상지의 지위지수를 산정한 결과, 지위지수가 18 이하로 낮은 지역은 8곳(18%)이었으며, 지위지수가 20 이상으로 우수한 지역이 37곳(82%)으로서 대부분 지역에서 지위지수가 우세하였다. 지위지수곡선의 적합도를 평가하기위해 수간석해목의 과거에서 현재까지의 수고생장에 따른 지위지수의 변화를 도시한 결과, 초기 임령 때 지위지수와 차이가 없는 곳은 단지 8지역(18%)이었으며, 지위지수가 2∼4 m 차이가 발생한 지역이 19곳(42%), 6 m 이상 발생한 지역이 18곳(40%)으로 나타났다. This study was performed to evaluate the compatibility of site index for Larix kaempferi in Gangwon and Kyeongbuk regions. The data were collected and analyzed from stem alalysis of one dominant tree at each of 45 permanent plots installed in the regions. The result of site index estimation following the site index table developed by Korean Forest Service (KFS) showed that 8 plots (18%) were less than site index 18 and 37 plot (82%) greater than site index 20. Height growth changes of stemmed trees until present were illustrated in a graphic form to evaluate the compatibility of site index curve. The result showed that only 8 plots (18%) did not show any change of site index as trees age, 19 plots (42%) fluctuated in 2∼4m and 18 plots (40%) over 6m.

      • Photodamage inhibition effects of Hermetia Illucens enzymatic extracts in UVB-stimulated keratinocytes

        Seo-Yeong Park,Min Ju Kim,Siwon Yoo,Jin Woo Song,Jong Min Choi,Seo Hee Lee,In Hwan Kim,Ginnae Ahn 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

        In this study, we prepared two enzymatic extracts by using trypsin and pepsin from Hermetia Illucens (THI and PHI), and evaluated their effects on photodamages in ultraviolet B (UVB)-irradiated human keratinocytes. The result showed PHI led to the higher extraction yield than THI, whereas the protein content of PHI was lower. Also both THI and PHI decreased the generation of intracellular reactive oxygen species (ROS) without the cytotoxicity at the used all concentrations in UVB-irradiated human keratinocytes. In particular, THI reduced the formation of apoptosis and the sub-G1 DNA content. In conclusion, we demonstrate that Hermetia Illucens enzymatic extracts suppress photo damages by inhibiting the oxidative stress of UVB-irradiated human keratinocytes. This research was supported by X-mind Corps program of National Research Foundation of Korea (NRF) funded by Ministry of Science, ICT (No. 2019H1D8A1109673).

        Effects of Cr<sub>2</sub>O<sub>3</sub> modification on the performance of SnO<sub>2</sub> electrodes in DSSCs

        Choi, Seo-Yeong,Kim, Min-Hye,Kwon, Young-Uk The Royal Society of Chemistry 2012 Physical chemistry chemical physics Vol.14 No.10

        <P>In this paper, we demonstrate that Cr<SUB>2</SUB>O<SUB>3</SUB>, a visible absorbing insulator, can be used as an efficient blocking layer material for the anode of dye-sensitized solar cells (DSSCs). We prepared SnO<SUB>2</SUB> electrodes surface-modified with Cr<SUB>2</SUB>O<SUB>3</SUB> with various Cr/Sn ratios and studied the effect of the modification on the performance of DSSCs. DSSCs with Cr/Sn ratios 0.02, 0.05, and 0.10 showed increased overall photon-to-electricity conversion efficiency from that of pure SnO<SUB>2</SUB>. Especially, the DSSC with the Cr/Sn ratio 0.02 showed a remarkably large increase by 55%. The electrode materials were analyzed by powder X-ray diffraction, transmission electron microscopy, N<SUB>2</SUB> adsorption studies, and UV-Vis diffuse reflectance spectroscopy. The Cr-containing species appears to be Cr<SUB>2</SUB>O<SUB>3</SUB> nanoparticles, spread evenly on the SnO<SUB>2</SUB> nanoparticles and filling the gap space between SnO<SUB>2</SUB> particles. The electrochemical properties of the electrodes were characterized by Mott–Schottky plots and electrochemical impedance spectroscopy. As the Cr-content increases, the flat-band potential is negatively shifted. The impedance spectroscopy data show that Cr/Sn = 0.02 and 0.05 samples have lower charge transport resistance at the electrode, which can be explained by the rise of the conduction level due to the charge transfer from the more basic Cr<SUB>2</SUB>O<SUB>3</SUB> nanoparticles to SnO<SUB>2</SUB> nanoparticles. These observations corroborate with the trends of the short-circuit current and the open-circuit voltage of the DSSCs.</P> <P>Graphic Abstract</P><P>Cr-modified SnO<SUB>2</SUB> shows more efficient photovoltaic performance than non-modified one because more basic Cr<SUB>2</SUB>O<SUB>3</SUB> makes SnO<SUB>2</SUB> electron rich making the conductivity increased. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c2cp23545e'> </P>
