Purpose: To compare the protective effects of saponin and non-saponin Sun-ginseng extract fractions in a selenite-induced rat cataract model. Methods: A total of 101 Sprague-Dawley rat pups were divided into four groups by treatment: Sun-ginseng, saponin fraction, non-saponin fraction, and control. For induction of cataracts, sodium selenite 15 nmol/g was injected subcutaneously in 13 day-old rat pups. Sun-ginseng extract 100 μg/g (Group I, Ginseng Science, Seoul, Korea), saponin fraction 100 μg/g (Group II), non-saponin fraction 100 μg/g (Group III), and phosphate buffered saline (Control group) were injected intraperitoneally every two days for a total of seven injections. The rats were sacrified and their lenses were dissected and photographed at day 7 and 14, and the cataracts were graded according to the ratio of the cataract area to the total lens area. The blind method was used for the evaluation of the cataract area. Results: At day 14, cataract formation rates (CFR) were 33.3% in group I, 76.4% in group II, 41.2% in group III, and 77.7% in the control group. The mean cataract area (MCA) was 13.4±20.8% in group I, 14.4±11.7% in group II, 5.7±7.7% in group III, and 15.8±12.1% in the control group. Group III showed statistically significant results compared with those of control group (CFR p=0.001, MCA p=0.001). We observed significantly lower incidence and smaller mean cataract area in Group I and Group III at day 7 compared with the control group (Group I, CFR p=0.018; Group III, CFR p=0.032, MCA p=0.005). Conclusions: The protective effects of Sun-ginseng extract are caused by the components in the non-saponin fraction, not by those in the saponin fraction, in a selenite-induced cataract rat model.

The paper reports on exploratory research into the factors influencing adoption of low impact development (LID) regulations by local government. The research uses ten case studies ranging from low to high level adoption of LID in Virginia. Based on the theory of diffusion of innovations, perceived characteristics of LID, characteristics of the adopting local government, motivations of the adopter, and the surrounding organizational context of the adopter are chosen for the key factors influencing on LID adoption. By reviewing the local governments regulations related to stormwater management, meeting minutes, reports and documents, and in-depth interviews, the evaluation of the key factors and the local LID adoption was conducted. As a result, adopters with a high level of LID adoption at the time of the study were heavily influenced by champions of LID within local government and communities. In contrast, moderate level adopters and low-level adopters emphasized the importance of external forces like state regulatory mandates and the need for clear models to implement.

박선아,정문선,이명우,Park, Sun-A,Jeong, Moon-Sun,Lee, Myungwoo 한국조경학회 2015 韓國造景學會誌 Vol.43 No.3

삭막한 도시환경으로부터 오는 스트레스는 도시민들에게 다양한 질병을 발생시키거나 건강을 악화시키는 반면, 자연은 인간에게 긍정적인 치유효과를 준다. 자연을 통한 치유프로그램은 활동공간의 특성에 따라 숲치유와 원예치료로 구분할 수 있다. 그러나 치유프로그램에 대한 연구는 독립적으로 이루어져 다양한 프로그램의 적용과 연계에 따른 효과를 파악하는데 한계가 있다. 따라서 본 연구는 숲치유와 원예치료의 생리적 심리적 효과를 비교 분석하여 각 프로그램의 효과와 차이점을 밝혀 향후 치유프로그램 개발과 치유공간 설계의 기초자료를 제공하고자 한다. 실험은 숲치유 5명, 원예치료 5명의 피험자를 대상으로 5일간의 프로그램에 대한 사전사후검사를 실시하였다. 생리적 반응은 혈압, 맥박, 코티솔 변화량으로 측정하였고, 심리적 반응은 기분상태검사로 측정하였다. 분석방법은 통계프로그램 SPSS 18.0 for windows의 분산분석(ANOVA)과 대응표본 T-test를 실시하였다. 연구결과, 1) 숲치유와 원예치료는 생리적, 심리적으로 모두 긍정적 효과를 보이며, 2) 숲치유는 원예치료보다 생리적 이완과 스트레스 감소에 더 효과적이고, 3) 원예치료는 숲치유보다 우울감 감소에 더 효과적인 경향이 있는 것으로 나타났다. 위 결과는 각 치유프로그램의 특징을 파악함으로써, 향후 치유프로그램 개발과 치유공간 설계를 위한 기초자료와 지침 설정에 도움이 될 것으로 기대한다. Stresses from desolate urban environments cause illnesses and worsen health conditions of urban residents, while natural environments have a positive influence on human. Natural healing programs such as forest therapy and horticultural therapy can be differentiated by the characteristic of activity space. However, previous studies of healing programs have focused on either forest therapy or horticulture therapy and there is a limit to comprehending the effects of adopting and connecting various healing programs. This study compares and analyzes the physiological and psychological effects of forest therapy and horticultural therapy to identify the effects and differences by types of healing programs. The before and after effects of horticultural therapy and forest therapy are measured by experiment and survey for 5 days with 5 subjects in each program. For physiological reaction, blood pressure, pulse, and cortisol levels are measured and the profile of moods states(POMS) is used to measure psychological reaction. Collected data are analyzed with the analysis of variance(ANOVA) and Paired-Sample T-test in SPSS 18.0. The results of this study are as follows: 1) forest therapy and horticultural therapy show positive effects in physiological and physiological aspects, 2) forest therapy is more effective than horticultural therapy in physiological relaxation and stress mitigation, 3) horticultural therapy has a tendency to alleviate depression more effectively than forest therapy. In conclusion, this study contributes to providing fundamental information for the development of healing programs and design guidelines for healing spaces through identifying the characteristics of each healing program.

This study aims to present primary data for habitat restoration and artificial breeding conditions of L. unmunsana by identifying the habitat conditions and the larvae's food sources. In order to investigate the habitat characteristics of the adult L. unmunsana and land snails, which are the primary food sources for the larvae, field surveys were conducted on a total of 10 habitats in south-central parts of Korea including Sanseongcheon, Jeonju. The results revealed that the L. unmunsana habitat in the Sanseongcheon area had a broadleaf forest with a multi-layered vegetation structure, adjacent water features, and the north/northeast/northwest slopes with little effect of artificial lighting. The adult L. unmunsana in the Sanseongcheon area appeared from the end of May to the end of June, and was especially intensively observed around the middle of June. The most active time was from 23:30 to 00:30 with a temperature range of 19~22℃ and higher than 80% humidity. The peak count of the observed adults L. unmunsana was a total of 774 on June 11, 2021. In the case of land snails, 11 families and 23 species were observed in 10 habitats of L. unmunsana, and Euphaedusa fusaniana was the most extensive and the most observed in the five survey areas. The land snails of L. unmunsana habitats are mostly found under the organic layers of leaves and a fallen tree branch in broadleaf forests, where a thick organic material layer buffers temperature changes and provides high humidity for various snails. These habitat conditions are suitable for the larva of L. unmunsana and land snails to inhabit, feed, hide and hibernate.

숲공간이 갖는 유아발달의 긍정적인 영향으로 다양한 사업주체에 의해 숲활동공간의 조성과 운영이 양적으로 증가하고 있으나, 실제적인 공간설계 및 운영프로그램에 관한 연구는 미흡한 실정이다. 따라서 본 연구의 목적은 숲활동에 참여한 교사와 유아를 대상으로 이용후 평가를 실시하여 유아숲체험장의 공간 및 운영프로그램을 평가하는데 있다. 이를 위해 서울시 유아숲체험장 12개소를 대상으로 현장조사, 수업참관, 숲교육 전문가 인터뷰를 통한 현황분석과 115명의 산림교육전문가 및 보육교사들에게 중요도, 성취도, 전반적 만족도, 공간선호도 설문조사를 하였다. 또한 29명의 유아를 대상으로 면담법, 사진 시뮬레이션, 유아용 설문지를 사용하여 전반적 만족도와 공간선호도를 파악하였다. 중요도 및 성취도 분석결과, 운영프로그램특성 영역이 공간특성 영역보다 높게 평가되었고, 구조적 프로그램의 적용 여부를 바탕으로 구분한 집단간 비교에서 적극적인 적용 그룹이 소극적/자유놀이 그룹보다 두 영역 모두를 높게 평가하였다. 유아설문결과는 구조적 프로그램을 적용한 유아들은 시설공간을, 자유놀이 중심의 유아들은 자연공간을 선호하였으며, 두 집단 모두 숲활동에 대해 '만족'하였다. 이를 바탕으로 1) 숲활동공간의 조성은 접근성, 안전성, 경사다양성, 수공간을 확보하고, 숲길로서 연결될 수 있게 하며, 다양한 지형과 수목 및 자연재료를 확보하도록 한다. 2) 운영 프로그램은 숲활동 프로그램을 체계적인 운영과 구조적 프로그램 및 자유놀이의 비율이 편향되지 않도록 한다. 또한 자유놀이시간의 충분한 확보와 숲속 공간에서의 놀이 점유율이 높은 운영 프로그램을 계획한다. 3) 산림교육전문가의 역할과 전문성을 확보하여 유아의 자율성을 높일 수 있는 프로그램을 운영하도록 한다. Due to the positive effect of forest space for child development, the creation and operation of forest activity space of various organizations is increasing in quantity; however, the research on practical space design and management program is insufficient. Therefore, the purpose of this study is to evaluate the space and management programs of the forest experience centers through the post-occupancy evaluation of teachers and preschoolers participating in forest activities. To do this, we analyzed the selected twelve sites through field survey, class observation, and interviews with forest education specialists, and then surveyed 115 forest education experts and childcare teachers for importance, performance, overall satisfaction, and space preference. In addition, we accessed overall satisfaction and space preference of twenty-nine preschoolers through interviews, photo-simulation, and questionnaires. As a result, the importance and performance of management program area was rated higher than the spatial characteristics area. In terms of group comparison, the group with active structured program rated two areas higher than the groups with free play. Preschoolers with structured programs preferred facility space, but preschoolers with free play preferred nature. Two preschooler groups rated forest activity as satisfactory. Based on the analysis results: 1) The composition of the forest activity space should ensure accessibility, safety, diversity of diversity, water space, connect to the forest road, and secure various terrains, trees, and natural materials; 2) The management program should ensure that forest activity programs have the proportional balance of structural programs and free play; also. management programs should plan for sufficient free playtime and a high share of play in the forest; and 3) Ensure the role and expertise of forestry specialists and run a program to increase the autonomy of preschoolers.

임현정 ( Lim Hyun-jeong ),김종만 ( Kim Jong-man ),정문선 ( Jeong Moon-sun ) 한국환경복원기술학회(구 한국환경복원녹화기술학회) 2021 한국환경복원기술학회지 Vol.24 No.2

The purpose of this study is to provide basic data for habitat restoration by implementing a series of processes of capturing and translocating Kaloula borealis and managing them in artificial breeding facilities. The study site in Samcheon, Jeonju-si, Jeollabuk-do was a waste landfill site in the past, and Kaloula borealis was found during the Samcheon Ecological River Restoration Project around March 2018. To restore the habitat, a plan was established to capture, translocate, artificially breed, and release Kaloula borealis at the site. The capture methods of adult Kaloula borealis were pitfall trap and drift fence, direct capture, and deep barrels. During 2018-2019, 86 adults of Kaloula borealis were captured and translocated to artificial breeding facilities. VIE-tagging was inserted under the skin for monitoring. For artificial breeding, Gryllus bimaculatus with oyster powder and vegetables were regularly supplied to feed Kaloula borealis. At the end of October 2020, 150 young Kaloula borealis raised in artificial breeding facilities were found not entering hibernation, so they were managed in a separate artificial breeding facility. Some young and adult Kaloula borealis currently hibernating will be sched-uled to be continuously managed in artificial breeding facilities and released to the restored habitat in the spring of 2021.

보험사기 판례에 대한 분석 및 입법론적 제언

홍명호(Myung ho Hong),정문선(Moon Sun Jeong) 한국보험법학회 2015 보험법연구 Vol.9 No.2

우리 상법상 사기에 기한 보험계약의 민사적 효과를 다루는 규정은 없다. 상법제669조, 제672조는 사기에 의하여 초과보험 또는 중복보험을 체결하게 된 경우 무효로 보고 있으나, 이는 손해보험 중 일부의 경우에만 적용되는 조항이며, 보험계약 일반에 적용되는 조항은 없다. 우리 법원은 현실에서 발생하는 사기에 의한 보험계약의 문제점을 인식하여 민법 제103조를 적용하여 보험계약의 무효를 선언하는 판결을 상당수 하고 있다. 이는 우리 법원이 법과 현실의 괴리를 민법의 일반조항으로 해결하여 구체적 타당성을 기하려는 의도로 보이는데, 이와 같은 일반조항에 의한 해결은 법적 안정성을 해치며 사회일반의 예측가능성도 저해하는 결과를 초래하고 있다. 이와 같은 법적 문제점을 해결하는 방법은 우리 상법에 사기에 기한 보험계약의 요건과 효과를 규정하는 것이 가장 적절한 대안이라고 본다. The Korean commercial law does not cover the civil effects of fraudulent insurance contracts. While Section 669 and 672 of commercial law state that the fraudulent overinsurance or multiple insurance is null and void, they only apply partially among non-life insurance and there exists no such clauses which apply to insurance contracts in general. The Korean court of law has handed down a ruling that such fraudulent insurance contract is null and void applying Section 103 of civil law in many civil cases as it is clearly aware of the problems with the fraudulent insurance contracts in reality. It seems that the court intends to pursue a concrete validity resolving the gap between law and reality through the general clauses of civil law. However, such application of civil law to fraudulent insurance harms the legal stability and it also leads to a result that it hinders the general expectations of society. The best alternative to resolve such difficulty is to regulate the requirements and effects of the fraudulent insurance contracts.
