Purpose: To report a case of a familial lecithin cholesterol acyltransferase (LCAT) deficiency patient with bilateral corneal opacities. Case summary: A 26-year-old man with bilateral corneal opacities visited our hospital. We took slit lamp examination, corneal thickness measurement, corneal endothelial cell counts and fundus examination. Blood and urine tests were included. Kidney biopsy was done. The tissues were observed by a light microscopy and an electron microscopy. Hemolytic anemia, proteinuria, hematuria, hypertriglyceridemia, decreased HDL cholesterol level, and lecithin cholesterol acyltransferase (LCAT) deficiency were found. At kidney biopsy, electron-lucent vacuoles and lamellar inclusion body were found. Conclusions: Bilateral corneal opacities can be an imporant clinical sign of systemic disease which is caused by abnormal lipid metabolism like the familial lecithin cholesterol acyltransferase (LCAT) deficiency.

This study looked at worked on remaining landscapes in terms of landscape ecology. It presented some ways to conserve and to activate remaining landscapes with examples of agricultural lands in Hwa-won Gun, Ok-po Myun. The results are as follows: We investigated 20 remaining landscape types and 90 remaining landscapes, and classified them in terms of forest and water zones. To evaluate the investigated remaining landscapes, we produced a grading system using 8 criteria such as vitality, stability, field suitability, type of inner scenery formation, connection, recreation, and culture/tradition. Our evaluation of the vitality found that Grade I had the mast remaining landscapes; Grade II had 28, Grade III had 16, Grade V had four, and Grade IV had none. We evaluated the outer landscape influence using 3 criteria such as divisibility, vitality, and indication. We found from evaluating the type of inner scenery formation that most of the landscapes superior to Grade III were adjacent to water zones and that linear landscapes evaluated as Grade I, and II played an important role in this connection. We evaluated the recreation probability using marks, frequencies, and emergencies of peculiar types. Based on the results, we proposed some ways to conserve and to activate the remaining landscapes classified by grades using the results of the last evaluation. Additionally, we proposed some ways to activate the restoration of the linear axis of the green space function the formation of a buffer green space around matric space, the improvement of the axis of the green space center, and the formation of additional green tracts of land to play the role of stepping stones. We proposed the possibility of improving uniformed farm land structures. This study did not consider the weighting values of the evaluation index. Therefore a more objective study will be needed with an expert-survey in the future.

The purpose of this research is to analyze of biotope structure focused on the evaluation for the species and biotope preservation in the case of Soosung District in Daegu metropolitan city. We analyzed the structure of urban biotope, and investigated the disposition of space and several characteristics through the material collection relating to the existing urban ecological material and the field investigation. The results of this study were as follows; 1) The result of biotope type classification was divided into 17 biotope type groups and 90 biotope types belonging to them. 2) The biotope type of mixed forest(QD) has the highest rate in occupation area, 1.764ha and the biotope type of cultivation areas by vinyle-hothouse(KC) has the lowest rate, 0.3ha. 3) In the result of the first evaluation for the species and biotope preservation, biotope types such as QB, QI, PA, PB, NB and NC etc. possess great value. Particulary, these biotope types come from forest areas and transition zone. They have not appeared in the inner of cities. 4) The biotope types such as CA, NA, NB, ND and PB are proved to possess high value in the result of rarity and riskiness evaluation. There appear EE, MA, NB, QC and QD in IV grade which is impossible to have them regenerative. They usually have appeared in forest areas. 5) There emerge 3a biotope type that has the highest value in the result of the second evaluation such as CC, EE, KF, LD, MB, NC, PB, QB and QI etc. Most of them were presented into the large area of site size and were distributed in the forest areas intensively. So, it is certain that the space for the species and biotope preservation connected with residential district is scarce. 6) The detailed biotope plan must be made out specially continuously. It is about biotope spaces that are especially important for the species and biotope preservation from the result of this research. Also, the study on the detailed index settlement of the urban landscape plan based on the biotope map must be continued.

Since 1950, forest policy of Korea has undergone a paradigm shift by the times. From the 1950s to the 1960s, strategies had been focused on the rehabilitation of forest and maintenance of legal system. During the 1970s and 1980s, forest preservation and economic value were highly regarded. Since 1998, policy and strategies have been expanded to application of forest resources for recreation, heath, and welfare. In addition, new forest policy with welfare was appeared for establishing green welfare country. The beneficiaries by the new forest policy are expected to rise steadily from 29 million in 2014 to 35 million in 2016. It is necessary to build up diversified forest policy and strategies as the demand for forest and the interest related to the new parts like the forest welfare services are growing. The purpose of this study is to do basic research for carrying out policy and strategies based on city-owned forest in Daegu. For this, it was performed to analyze on the status of city-owned forest and to derive relative importance and priority from the experts questionnaire investigation. 우리나라 산림정책은 1950년대 이후 시대별로 변화의 과정을 겪게 된다. 1950년대부터 1960년대까지는 산림복구와 제도정비에 초점을 맞추었고 1970년대 이후부터 1990년대 사이에는 산림보호와 산림의 경제적 가치를 다루는 정책이 이루어졌다. 1998년부터는 지속가능한 관점에서 휴양·건강·복지를 위한 산림자원 활용 정책이 확대되기 시작하였으며 녹색복지국가 실현이라는 새로운 산림복지정책이 출현하였다. 새롭게 추진되는 산림복지정책의 수혜인구는 2014년 2,999만 명에서 2016년 3,530만 명으로 꾸준히 증가할 것으로 전망된다. 산림의 수요는 여전히 높고 또한 산림이 국민적 복지자원이라는 인식이 확산되면서 산림복지서비스라는 새로운 분야에 관심이 더욱 높아짐에 따라 다각적인 산림복지정책을 수립하는 것이 필요하다. 본 연구는 대구시가 소유하고 있는 시유림을 토대로 산림정책을 실현시키기 위한 기초연구를 하는데 그 목적을 두었다. 대구 시유림 현황을 분석하고 전문가 설문분석을 통해 시유림 정책의 상대적 중요도와 우선순위를 도출하고자 하였다.

나정화 한국조경학회 2001 韓國造景學會誌 Vol.29 No.2

The purpose of this study is to assess naturalness of each and use type for Daegu and provide the basic data for urban green space planning. The results are as follows: 1) As a result of periodic analysis, It is known that in the 1400´s that the rate of a-/oligo-/meso-hemeroby was over 90% of that area, in which naturalness was very high. By the 2020´s, the population will increase to about 3,500,000 and the occupation rae of meat-and poly-hemeroby, where naturalness is very low, is expected to increase rapidly. 2) The recent land uses of Daegu are divided ito 17 types. In the survey of a occupation rate of each land use type, a forest are occupies 48.8% of the entire area. The military installation zone is lowest with 0.07%. 3) Investigation of a dominant hemeroby grade in each land use type showed that the urban complex area in characterized by meta-hemeroby : and the space for pavement and building construction where naturalness is lowest. On the other hand, oligo-hemeroby that is worth being preserved was surveyed to be dominant in woodlands and natural forests. 4) In the analysis of hemeroby mapping in the process of a green space planning, it is clear that hemeroby will be used a s a tool that assesses the suitability for recreation activity of each sample case. For example, it enables a poly-hemeroby region to be utilized as a near-natural recreation area including $\beta$-and $\alpha$-euhemeroby region in Daegu. Besides, hemeroby can provide basic data to make a value judgement of each sample case with a view to preservation of nature.

The purpose of this study is to evaluate naturalness of botanical garden pre- and post-assessed according to the Hemeroby Index in the case study of Daegok Botanical Garden. The results of the study are as follows. 1) The results of the site analysis according to the Hemeroby Index before development have been appeared that highest of poly/meta-hemeroby is 45.8% and the next of meso-hemeroby is 28.3%. 2) After development, the highest of meso-hemeroby is 53.6% and the next of $\alpha$ -euhemeroby is 28.3%. Generally, it is considered that the naturalness according to Hemeroby Indx was lasted higher after development than that before development. 3) Both a-hemeroby and oligo-hemeroby are not appeared before and after development. $\alpha$ -euhemeroby and meta-hemeroby are not appeared before development, but htey increased as much as 16.8% and 6.8% after development. Most of all, the increase of meta-hemeroby after development results from the increase of the artificial facilities (e.g. pavements, buildings and so on). 4) Specially, through the modification of play ground, park lot, pavement classified to meta-hemeroby, it is considered that the Hemeroby Index would be improved. 5) Compared with existing naturalness grade of green space, it has merits to apply Hemeroby Index, especially as a menas of distinguised naturalness assessment in various land use pattern. But there is no clear evidence that limits the minimum size that could be applied with Hemeroby Index. So, we must discuss whether it was useful to apply this standard to such a small specific space as the site of this study.

난시교정인공수정체 삽입 후 임상 결과

나정화,이현수,주천기 대한안과학회 2009 대한안과학회지 Vol.50 No.6

Purpose: To evaluate the short-term efficacy of astigmatism correction and rotational stability of AcrySof Toric Intraocular lens (IOL) implants. Method: We analyzed 27 eyes of 23 patients who underwent microcoaxial cataract surgery (MCCS) and AcrySof Toric IOL implantation between March 2008 and July 2008. We evaluated visual acuity, keratometry, and refraction. Slit-lamp retroillumination photographs were obtained in all patients on 1 day, 1 month and 3 months postoperatively. The change of postoperative IOL axis alignment and the presence of anterior capsular shrinkage were analyzed. Result: The mean unaided visual acuity (LogMAR) improved from 1.02±0.38 to 0.10±0.12. Although postoperative manual keratometric value was not different from the preoperative value, post-operative astigmatism decreased from a mean value of 1.66±0.42D to 0.61±0.38D at 3 months postoperatively. The mean difference between achieved and intended lens axis was 1.63±2.83 degrees at the first post-operative day, and 1.91±2.92 degrees on the first postoperative month, with all cases within 10 degrees. There were two cases of IOL rotation between one day and one month postoperative follow-up, and severe anterior capsule contractions were found in them. Conclusions: AcrySof Toric IOL is effective for correction of astigmatism and it has good post-operative rotational stability. Because most of misalignments were found at the postoperative day 1, the precise implantation of IOL, according to the intended axis, can be important during operation and immediately after the operation. 목적: 백내장과 함께 각막 난시를 교정하기 위한 AcrySof 난시교정인공수정체(Toric intraocular lens, IOL)의 단기 효과와 안정성을 알아보았다. 대상과 방법: 2008년 3월부터 7월까지 미세절개백내장수술 및 Toric IOL 삽입술을 받은 23명(27안)을 대상으로 술 전후 시력, 자동굴절 검사 등을 분석하고, 술 후 1일, 1개월, 그리고 3개월에 전안부 촬영을 통해 IOL 축의 회전과 전낭 수축 정도를 관찰하였다. 결과: 나안시력(LogMAR)은 1.02±0.38에서 술 후 0.10±0.12로 향상됐으며, 자동굴절검사상 난시가 1.66±0.42 Diopter (D)에서 술 후 0.61±0.38D로 감소하였다. 의도한 축과 삽입된 축의 각도 차는 술 후 첫 날 평균 1.63±2.83도, 1개월에 1.91±2.92도였고, 모두 10도 이내의 회전을 보였다. 술 후 1일 후 1개월 내 IOL이 회전한 경우는 2안인데 뚜렷한 전낭 수축을 보였다. 결론: AcrySof Toric IOL은 백내장 수술과 함께 난시를 교정할 수 있는 효율적인 인공수정체이다. 술 후 1일 IOL축이 가장 많이 회전되 므로 수술 시와 수술 직후 축의 회전에 주의해야겠다.

나정화,류연수,사공정희 한국조경학회 2001 韓國造景學會誌 Vol.29 No.1

The purpose of this study is to construct the evaluation criteria based on the relative importance and various combination of each evaluation index and then to evaluate urban biotope in terms of conservation of species and habitat. After the standard of evaluation had been developed through the literature review, the relative importance of the evaluation index through expert survey was found out, and the evaluation model of biotope value has been established. The results of this study are as follows; 1) We have constructed the nineteen evaluation criteria through literature reviews, and have provided relative importance to each evaluation index of the diversity of typical species in biotope, afforestation rate, stratification, Hemeroby grads, and the diversity of landscape patterns based on the results of expert survey. and then we have constructed the evaluation system using the relative importance criteria. 2) To evluate urban biotope using the evaluation system constructed, we selected 14 sites. The final evaluation results of each site is as follows; The III grade areas are Seohan and Hwasung high-rise apartment at Beummul-Dong, Korea Men Power /Agency in Sungs 대 industrial zone, the adjacent area of St. Tongil, and Hyomyung elementary school. The II grade areas are the farm land behind the third Anshim Jugong apartment, and Ehyun park. The I grade areas are swampy land in front of Kangchon and Anshim construction site, water space with semi-natural style in front of Gangchon Woobang apartment, forest zone near page Temple at mt. Palgong, the edge area of Jisan and Gosan, and the tendril yard against Anshim middle school. The only grade IV area is the commercial zone near Taegu Department 3) It is highly useful to evaluate urban biotope using the evaluation criteria constructed for this research, the evaluation criteria we developed may be difficult to guarantee the ability for reproduction and recovery, the appearance-number of the rare and endangered species are difficult to estimate urban biotopes. In the future, it is highly useful to evaluate biotope in terms of conservation of species and habitat through its valuation criteria developed in this research and it is necessary to develop the evaluation criteria applicable to estimation of biotope inventory and reproduction of biotope.

농촌 및 자연지역의 경관 다양성 평가모형 개발 및 적용

나정화,이용은,조현주,구지나,권오성,Ra, Jung-Hwa,Lee, Yong-Eun,Cho, Hyun-Ju,Ku, Ji-Na,Kwon, Oh-Sung 한국조경학회 2013 韓國造景學會誌 Vol.41 No.6

최근 경관훼손 문제에 대응하기 위해 사전 예방적 차원에서 우수한 경관지역을 선정하려는 노력이 이루어지고 있다. 특히 경관 다양성은 경관 구성요소를 평가하기 위한 핵심적인 방법으로 보존가치가 높은 지역의 경관 질을 평가하는데 중요한 기준이 될 수 있다. 따라서 본 연구는 경관을 구성하고 있는 다양한 요소들을 고려한 경관 다양성 평가모형을 설정해 보고, 이를 연구대상지에 적용해 봄으로써 평가모형을 검증하는데 가장 큰 목적을 두었다. 국내 외 문헌 및 연구 자료를 분석한 결과, 경관 다양성 평가모형을 구축하기 위한 지표로서 지형, 식생, 토지이용형태, 특이경관 등 총 4개의 항목이 도출되었다. 지형의 다양성은 지표면 기복정도와 지표면 형태의 다양성을 세부지표로 선정하였으며, 식생의 다양성에서는 식물군락과 층위구조의 다양성을 세부지표로 선정하였다. 각 평가지표의 다양성을 정량적으로 평가하기 위하여 Shannon의 다양성 지수(SHDI)를 응용하였으며, 작성된 각 지표별 유형분류도면에 귀속되는 출현유형과 면적을 Fragstats 4.0에 대입하여 결과값을 산출하였다. 마지막으로 세부지표별 결과값의 표준화 및 합산과정을 거쳐 최종 경관 다양성 지수값을 산출하였다. 이러한 본 연구의 결과는 경관 다양성 평가의 초기 연구 단계로서 방향제시 및 가능성을 모색해 보는데 의의가 있었다. 또한 추후 연구를 통하여 경관 구성요소를 평가하는 핵심 방법으로서, 우수한 경관의 질을 평가하는 중요한 기준으로 활용될 가능성이 있을 것으로 사료된다. 그러나 본 연구에서 제시한 경관 다양성 평가모형은 4가지 지표를 종합적으로 고려하였던바, 우세성을 가지는 세부지표에 대한 고려가 반드시 필요할 것으로 사료된다. 더불어 각 평가지표의 결과값을 표준화하는 과정에서 차후 평가지표별 최대값에 대한 축척된 자료가 보완되어야 할 것으로 사료되며, 다양한 면적과 유형의 사례지들을 분석하여 객관성을 높여 나갈 필요가 있을 것으로 판단된다. Recently, to prevent damage to the landscape, outstanding landscape areas have been designated in advance. In particular, as a fundamental way to evaluate landscape elements, landscape diversity is an important criterion to assess an area with a high conservative value. Therefore, the purpose of this study is to develop a quantitative evaluation model of landscape diversity based on landscape elements and to verify the model by applying it to the study sites. The assessment indicators derived from the literature analysis are topography, vegetation, land-use pattern, and unusual landscape. Topography diversity is subdivided into land undulation and land-form. Vegetation diversity is subdivided into plant community diversity and stratification diversity. To quantitatively analyse each indicator's diversity, SHDI was selected as the central metric. All of the quantitative measures were implemented by using the statistical tool, FRAGSTATS. Through the process of each indicator's standardization and summary, the final landscape diversity index was calculated. The results of the study are significant as it was the initial study of landscape diversity evaluation to seek applicability. However, the results of the Landscape Diversity Evaluation Model in this study based on 4 indicators synthetically demonstrate that more than one or two outstanding indicators can be underrated. Therefore, each 4 assessment indicator results should be considered individually. Furthermore, using the maximum value for each indicator's standardization reflects that it is necessary to analyse various examples to obtain higher objectivity later.
