강정원,엄철환,Kang, Jung-Won,Eom, Chul-Whan 한국반도체디스플레이기술학회 2007 반도체디스플레이기술학회지 Vol.6 No.2

Optical simulation of the rear and front panel geometries were needed to improve the luminance and efficiency in PDP cells. The 3-dimensional optical code can be used to analyze the variation of geometries and changing of optical properties. In order to improve the accuracy of simulated results, a new UV source, called a multi-cubes UV source, was designed. To design the source, at first UV distribution was calculated with the plasma fluid code and then the UV distribution was transformed to the multi-cube structures in the optical code. Compared to the results from existing UV source, called a planar UV source, could be improved the accuracy of visible light distribution. Simulated results were also compared to the visible distribution measured with the ICCD in a real PDP cell.

강정원,손홍배,Kang, Jung-Won,Son, Hong-Bae 한국반도체디스플레이기술학회 2008 반도체디스플레이기술학회지 Vol.7 No.3

The electro-optical characteristics of the Liquid Crystal on Silicon (hereinafter "LCOS") micro-display on vertically alignment (VA) mode were studied depending on various cell gaps. 5 different cell gaps, such as $1.4{\mu}m,\;1.8{\mu}m,\;2.1{\mu}m,\;2.4{\mu}m$ and $2.8{\mu}m$, were selected. The reflectance-voltage (R-V) characteristics, distributions of reflected light and reflectance were calculated with 3-dimmensional LC code. At the center of cell, the smallest $1.4{\mu}m$ cell gap showed the lowest reflectance and the largest $2.8{\mu}m$ cell gap showed the highest reflectance due to the surface anchoring effect. In case of $2.1{\mu}m$ cell gap, the sum of reflectance overall cell was the highest value. Considering the reflectance and RV curve characteristic, the optimized cell gap was $2.1{\mu}m$.

시화호 표층과 주상시료 퇴적물의 유기탄소(Co$_{org}$), 유기질소(N$_{org}$), 중금속(Zn, Pb, Cr, Cu, Mn)의 함량과 분포를 규명하기 위하여 '97년 4월, 9월 그리고 '98년 3월에 총 30개의 퇴적물 시료가 채취하였다. 분석결과 표층 및 주상시료 퇴적물의 유기탄소${\cdot}$질소 그리고 중금속들의 함량과 분포는 조사시기와 정점별 차이에 따른 변화를 나타냈다. 표층 퇴적물의 유기탄소와 유기질소 함량은 시화호 안쪽의 육지에 인접할 수록 높은값을 나타냈다. 이러한 분포는 주변 하천 및 공단으로부터의 영향인 것으로 사료된다. 표층 퇴적물의 중금속 함량은 유기탄소 함량과 일차적인 관계가 있다고 해석된다. 주상시료 퇴적물의 C/N비의 변화폭은 3${\sim}$32이고 평균은 13.9를 나타냈다. 주상시료의 중금속함량분포 경향은 유기탄소와 유기질소의 함량분포 경향과 유사하였다. 표층 퇴적물의 중금속 함량을 방조제 축조 이전과 이후로 비교했을 때 축조 후 증가한 중금속은 Cu이고, 반대로 낮은 함량을 보이는 중금속은 Zn와 Mn으로 조사되었다. 이와는 달리 Pb의 함량은 일정하였다. 시화호 배수갑문 내측 주변과 방조제 외측 연안 퇴적물의 중금속함량은 유사하였다. Distributions of organic carbon (Co$_{org}$), organic nitrogen (N$_{org}$), and heavy metals (Zn, Pb, Cr, Cu, Mn) were investigated in Lake Shihwa sediments. Surface and core samples were collected in April and September, 1997 and March, 1998 for the study. The results show that these components contents are variable with sampling timeand station. In surface sediments, both Co$_{org}$ and N$_{org}$ have similar distribution pattern in which their high contents found in stations located near the land, indicating that the streams and industrial wastes seem to act as point sources. The C$_{org}$ contents are linearly related with those of heavy metals. It appears, therefore, that the distribution of heavy metals may be partly controlled by a complex interplay of biogenic, terrestial, and anthropogenic factors. The C/N ratios from three stations are in the range of 3-32, with an average of 13.2. Vertical profiles of heavy metals in sediment cores are similar to those of C$_{org}$ and N$_{org}$. Copper content of sediments is enriched compared to that of reported value before dike construction, but Zn and Mn are not deposited considerably. Especially, Pb content show less variable. Currently, anthropogenic effects of industrial complex may not reached to drainage gate area where heavy metal contents are comparable with those adjacent to coastal sediments.

Japanese government had intended to establish the Forest Ownership in accordance with the modernized laws and terminate the ownership disputes through the project for surveying the forest. This research is purposed to analysis the survey report for the land in disputes called Bunjangjijoseo(『紛爭地調書』) in Kimhae, Kyungsang Province and review how to treat the customary Forest occupation by Kimhae Citizen at the project process. During the Project, 191 disputes for 285 lots were occurred in Kimhae which was over most area in Kimhae. At that time, the Forest was occupied by Kimhae citizen in the manner of grave, sales & purchase, Planting trees, recording on land registration and certification, drafting a plan and others. However, the forest without ownership relation for long time was enlisted as the state forest at the state forest identification(or classification) survey which was made on and about 1911-12 year, and then leased to the 3rd parties on the condition of planting trees. This caused the Japanese to occupy the most of forest with considering the land area and lots. Consequently, the parties to the dispute for the forest were the local residents and the state as well as the local residents and Japanese who had leased the forest. Most of disputes in Kimhae area were for the state forest and settled in favor of the leaseholder except 10 lots. The settlement of the disputes over the forest in Kimhae was the process to create the state forest. The Japanese government unilaterally admitted and recognized the ownerless mountains as the state ones based on the modernized ownership conception. Further, the previous ownership interests and rights over the forest were not recognized on the unconditional basis of the current Planting trees and actual result. In consequence, the state forest was reproduced and enlarged, and most of the Japanese who were the leaseholders won the cases, were able to push on planting trees and have more chance to secure the ownership interest on the forests. This made the local resident in Kimhae unable to exercise their influence over the forest slowly and to join the operation of forest resources under the control of the Japanese.

본 연구는 어린이집 팀티칭 반에서 초임교사가 인식한 자기결정성과 경력교사의 사회적 지지가 초임교사의 전문성 인식에 미치는 영향을 알아보고자 하였다. 이를 위해 서울, 경기, 인천 지역 소재 어린이집에서 근무경력 3년 이상의 경력교사와 함께 팀티칭 하는 초임교사 141명을 대상으로 설문을 실시하였으며, 독립표본 t검증, 일원변량분석 및 Scheffé의 사후검증, 중다회귀분석을 실시하였다. 연구 결과, 첫째, 직장어린이집에서 근무하는 초임교사가 국공립·법인어린이집과 민간·가정어린이집의 초임교사 보다 자신의 자기결정성, 팀티칭 경력교사의 사회적 지지, 교사의 전문성을 긍정적으로 인식하였다. 또한, 팀티칭 경력교사의 경력이 낮은 경우 초임교사가 경력교사의 사회적 지지 중 정서적 지지를 긍정적으로 인식하는 것으로 나타났다. 둘째, 초임교사가 자신의 자기결정성을 긍정적으로 인식하고 팀티칭 경력교사로부터 사회적 지지를 많이 받는다고 느낄수록 자신의 전문성 수준 또한 높게 인식하는 것으로 나타났다. 결론적으로, 어린이집 팀티칭 반에서 초임교사가 인식한 자기결정성과 경력교사의 사회적 지지는 초임교사의 전문성 인식에 영향을 미친다. 본 연구의 결과를 통해 초임교사를 지원하는 방법으로써 경력교사와의 팀티칭을 통한 효과, 경력교사 역할의 중요성 및 교육지원의 당위성에 관하여 논하였다. Objective: This study set out to investigate the effects of self-determination and experienced team-teaching teachers" support perceived by beginning teachers on their awareness of professionalism at daycare centers. Methods: The participants include 141 beginning teachers providing team-teaching at daycare centers in Seoul, Gyeonggi Province, and Incheon city. An online questionnaire was distributed and collected by mail and email or online questionnaire. Collected data was put to the independent-sample t-test, one-way ANOVA, and Scheffé post hoc test. Multiple regression analysis was conducted to investigate the effects of beginning teachers" self-determination and experienced team-teaching teachers" support on beginning teachers" awareness of professionalism. Results: First, beginning teachers working at work daycare centers positively recognized their self-determination and experienced team-teaching teachers" support, professional perception of the beginning teachers rather than beginning teachers at public and corporate daycare centers and private and family daycare centers. In addition, if the experience of a experienced team-teaching teacher is low, the beginning teachers are found to be positively aware of the emotional support among the social support of experienced team-teaching teachers. Secondly, controlling for the type of institution currently employed by beginning teachers and the experience of a experienced team-teaching teacher, when beginning teachers had a positive perception of their self-determination and felt that they received much support from the experienced team-teaching teacher in the same class, they tended to have high awareness of their professionalism. Conclusion/Implications: The findings demonstrate that beginning teachers" self-determination and experienced team-teaching teachers" support perceived by them had effects on their awareness of professionalism at daycare centers.

일제시기 산림에서 신고의 의미와 소유권‘법인’

강정원(Kang, Jung won) 한국외국어대학교 역사문화연구소 2019 역사문화연구 Vol.70 No.-

일제는 삼림법 신고를 토대로 마련된 미신고지의 국유화를 통해 국유림 조사를 시행하고 국유림을 운영하였다. 삼림법의 신고는 일제가 국가 주도의 산림정책을 추진해 나갈 수 있는 원천이었다. 미신고지의 국유화에서 초래된 문제는 연고권과 대부권을 부여하여 조정해 나갔고, 임야조사사업에서는 이를 수렴하여 ‘신고를 불문하고’라는 조항을 두어 국유림과 민유림에서의 소유권을 확정해 나갔다. 삼림법 신고주의는 조선특별연고삼림양여령까지 법적 효력을 발휘했다. 단계별로 살펴보면, 첫 번째는 국유림 조사(삼림법~국유림구분조사) 시기이다. 이때의 신고는 사유 인정의 전제조건으로, 국유림의 범위를 정하였다. 일제는 신고를 전제로 구분한 국유림을 대상으로 각종 처분정책을 추진했다. 두 번째는 민유림 조사(임야조사사업~조선특별연고삼림양여령) 시기이다. 사업에서는 삼림법의 신고림과 연고림을 신고대상으로 삼고 소유권을 인정했다. 연고림 가운데서도 소유를 인정해 주었지만, 제한적이었다. 조선특별연고삼림양여령도 삼림법 신고를 전제로 추진했다. 일제가 국유림에서 추진한 각종 처분정책인 대부, 부분림, 토석 채취 등을 위해 허가된 임야는 삼림법의 신고를 전제로 한 정책으로 연고림 양여대상에서 제외되었다. 양여령으로 민유림이 증대되었지만, 이는 철저하게 식민지 권력이 주도한 결과였다 일제가 산림 소유권을 확정하는 과정에서 기본 전제는 신고였다. 신고를 통해 대규모의 국유림을 확보하였고 이를 토대로 국가 주도하에 일사분란하게 산림정책을 수립 운영해 나갈 수 있었다. 신고의 틀이 유지되는 가운데 일제는 사정과 재결을 통해 소유권을 법적으로 확인하였고, ‘原始取得’이라는 법적 효력을 부여했다. 기존의 권리관계를 소멸시키고 일본 민법이 정한 배타적 소유권을 부여함으로써 그동안 제기되었던 분쟁을 일소하고 식민지적 산림 소유권이 완성되었다. The Imperial Japanese government surveyed and managed national forests through nationalization of unregistered lands arranged in accordance to the Forest Act(森林法) registration. The problems caused by the nationalization of unregistered lands were settled by granting preemptive rights(緣故權) and loan rights(貸付權), and ownership in relation to national forests and civil-owned forests was finally confirmed through the Forest Land Survey Project(林野調査事業). The Forest Law registration system was legally effective until Joseon Special Preemptive Forest Concession Act(朝鮮特別緣故森林讓與令). As for the phased enforcement of the Forest Law, the first phase corresponds to the period of National Forest Survey (Forest Law~National Forest Classification Survey). At this time, registration was a prerequisite for recognition of private ownership, and the scope of national forest was determined. The imperial Japanese government implemented various disposal policies on national forests classified according to the required registration. The second phase corresponds to the period of Civic-owned Forest Survey (Forest Land Survey Project~Joseon Special Preemptive Forest Concession Act). Registered forests and forests with personal relationship under the Forest Law were subject to registration at this time, and ownership was acknowledged accordingly. Ownership was acknowledged for some forests with personal relationship, but such cases were limited. The Order of Concession for Joseon Forest Land with Special Personal Relationship was also implemented on the premise of the Forest Law registration. The forests and lands approved for various disposal policies implemented by the imperial Japanese government, such as loan, profit-sharing forest, soil and stone collection, worked on the premise of the Forest Law registration and were excluded from concession cases of forest with personal relation. In other words, ownership of these forests and lands was acknowledged only when the conditions for permission were met. Registration was the basic premise adopted by the imperial Japanese government in the process of determining ownership of forest. The content and meaning of registration differed slightly by period, but the stipulation of registration in Article 19 of the Forest Law was never denied or abandoned. Maintaining the framework of registration, the Japanese government confirmed ownership of forest and land through assessment and judgement and gave the legal effect of original acquisition(原始取得). By extinguishing existing rights relations and granting exclusive ownership as set forth by the Japanese Civil Law, the imperial Japanese government eliminated disputes that have been raised so far and completed the colonial forest and land ownership system.

일제시기 창원군『임야조사서』분석과 소유구조 변화

강정원(Kang Jung-won) 湖西史學會 2011 역사와 담론 Vol.0 No.59

This article analyzes the Research Paper of Forest in Chang-Won County which is the original evaluation based on the researches of woodlands and the survey of each lot. It is to grasp the currents of the ownership of national forests and civil-owned-fields in Changwon and understand the ownership changes. The Paper shows that the civil-owned national ratio(85% of the total lots and 67% of the total area) is far greater than the national(15% of the lots and 33% the area). The private ownership is greate importance in civil ownership(98.5% of the lots and 98.1% of the areas). Changwon county's national forests have some special features like this. First, the Yungorim(緣故林)of the Bulyojonrim(不要存林) holds the majority in the total nationals and most of their loans are alloted to the pro-government groups or to its townships. Second, there's no the Yungorim of the Ipheaguanhang. Third, there are many forests which have military purpose in Jinhea and Chunga. The civil-owned forests have some features too. Its share rosed slightly by the forest survey. It also shows that the town ownership has increased for securing its finance on the one hand and for getting the town located in colonial regime on the other. The project has changed the ownership. First the national forests has increased by the way of reversing the Yun-Go-Rim to the national treasury. It was a result of the fact that the Gemynagsiljuck(禁養實積) was just alone applied as a criterion. There was no overall considering that could determine the right of the Yungorim being relevant to the occupations. Second the poor private ownership was created. That was the reason why the research made the management structure not based on the using rights but based on the ownerships. The group ownership like a family land(宗中) and gye(契) was also excluded. Because the project substituted the ownership of autonomous community for the joint-ownership the group ownership and the right of joint use were restricted or dismantled. Those policies individualized the ownership and promoted the small scale ownership widespread.
