Objectives: This study aimed to survey the characteristics of air quality and meteorological conditions in a greenway park. Methods: We measured meteorological and health related factors, including noise, particulate matter ($PM_{10}$) and selected gaseous air pollutants at three locations in a greenway park and on a general roadside as comparison. The measurements were repeated four times from April to October 2014. Results: The average air temperature in the greenway park was $20.7^{\circ}C$ which was $1-2^{\circ}C$ lower than on the general roadside. The average $PM_{10}$ concentration in the greenway park was $85.0{\mu}g/m^3$, a level 2-3 times lower than that at the roadside. The noise level at the greenway site was 4.4 dB(A)- 23.0 dB(A) lower than at the roadside. The average CO, $CO_2$, $SO_2$ and NOx concentrations in the greenway park were lower than at the roadside. The average phytoncide and anions concentrations in the greenway park were higher than at the roadside. Conclusions: The urban forest of the greenway park may have some impact on air quality and meteorological conditions.

" The Korean Journal of Chemical Engineering " 게재 논문 요약 : Processabilities & Mechanical Properties of the Biodegradable LDPE / Modified Starch Blends

Young Jin Kim,Yong Man Lee,Hyang Mok Lee,O Ok Park 한국화학공학회 1994 NICE Vol.12 No.5

N/A An investigation of the biodegradable polymers based on starch has been accomplished. Starch needs to be modified before blending with low density polyethylene(LDPE) because of its hydrophilicity. Three kinds of modification methods were applied to obtain the compatibility to starch-LDPE blends. The first one was the esterification of the hydroxyl group of starch with acetic anhydride. The second was the copolymerization of actylonitrile and styrene onto starch. The last was the esterification reaction of the hydroxyl group of starch with three kinds of ionomers. The tensile strength, % elongation, Young`s modulus, and shear viscosities of blends of the modified starch and LDPE were examined. Ionomer-treated starch showed better compatibility with LDPE to give better performances than other blends.

Backgrounds Cigarette smoking is a major cause of lung cancer and COPD. Smoking cessation should be recommended at any age to prevent disease. But a question can be raised if recommendation to stop smoking in elderly is equally effective compared with non-elderly people. Because myth like stereotype exists about elderly people that they are prone to think they have lived long enough so that they don't try to put any effort to change their old habit. In this study, we will find if the abstinence rates are significantly different between non-elderly(< 65) and elderly( >=65) age group. Methods Current smokers had participated in intensive smoking cessation camp at Chonnam national university hospital between 2015 and 2017. We performed a retrospective study to figure out the differences of abstinence success rate between elderly and non-elderly groups. We followed up patients at 6 months from start of abstinence and 2019 year for long term follow-up. Logistic regression analysis was done to figure out which factors were associated with long term success rate of smoking cessation including age group, comorbidities, CO value, regular exercise which were statistically significant in chi-square test or standard t-test. Results Total 351 patients were enrolled. 51 of 81 (62.9%) patients in elderly and 74 of 181 (40.8%) in non-elderly were successful in maintaining abstinence at the time of long term follow up. Age group was not statistically significant in logistic regression analysis (p = 0.07, 95% CI = 0.956 - 3.205). 6 month abstinence was statistically significant in long-term success of abstinence (p = 0.003, 95% CI = 1.311 - 3.910). Conclusion There was no inferior result of abstinence success in the elderly. We can suggest elderly smokers quit their old habit because they are as eager as young-aged people to change.

제초제 MCPP에 의한 화학적 화상

MCPP (2-(4-chloro-2-methyl phenoxy) propionic acid) is a phenoxy herbicide found in many household weed killers and lawn fertilizers. Some of the phenoxy acids, salts, and esters are moderately irritating to skin, eyes, and respiratory and gastrointestinal linings. In a few individuals, local depigmentation has apparently resulted from protracted dermal contact with phenoxy compounds. Although acute irritant contact dermatitis induced by herbicides is common, chemical burns induced by herbicides have been reported infrequently in the literature. Here we describe a chemical burn in a 25 year old female after sitting on a lawn that had been sprayed with MCPP 3 days earlier. This case illustrates potential hazards of the herbicide on the lawn of a public park. (Korean J Dermatol 2011;49(10):936∼939)

Purpose: With the recent boom in 'eating healthy', many adults are interested in dieting to prevent future diseases. However only well trained experts can distinguish between what are edible vegetables and herbs from their poisonous look-alikes. In cases where a patient unknowingly ingests a poisonous herb, is caught off guard by the poisonous side effects that occur because of their lack of knowledge of what they have ingested. This paper will focus on the need to educate the public about the risks involved with ingesting wild vegetables and herbs and study the emergency diagnosis and treatment of poisoned patients that enter the emergency room. Method: This study was done in the spring of 2004 (from March to May) in the Kangwon Young-Seo districts of Korea. 15 subjects used in this study, entered the emergency room showing signs of toxic symptoms. Data was collected by examining subject's records. Additional data was collected by collaborating with physicians in the hospital that diagnosed and treated the subjects. Identifying the poisonous vegetable or herb is the first step to proper diagnosis and treatment. Subjects admitted to the emergency room, underwent a battery of tests: laboratory examination, ECG, radiological exam and etc. Results: The demographics of the study encompassed subjects with the average age of $50{\pm}19$ years old. There were 10 men and 5 women. Common symptoms of this study included; gastrointestinal symptoms such as nausea, vomiting, epigastric pain and so on. In the case of Caltha palustris ingestion, additional symptoms were present; bradycardia and hypotension which lasted for a long time. While cases that ingested Scopolia parviflora had little effect on vital signs but manic episodes lasted for about three days. Veratrum patulum ingestion showed signs of bradycardia and hypotension but contrary to Caltha palustris recovery was shorten by treating with dopamine. However, dizziness, headache and paresthesia of the extremities continued for a long time. Finally Sium ninsi ingestion showed visual disturbance, paresthesia of the extremities, dizziness as their initial symptoms. Conclusion: The risks involved with ingesting wild plants without the proper knowledge can lead to serious side effects and steps need to be taken to educate the public. In addition, all emergency physicians need to have a working knowledge of the symptoms and signs associated with ingesting toxic wild plants and need to treat accordingly.

본 연구는 독립훼손지 중 아고산대에 위치한 지리산국립공원 세석평전과 노고단 복원식생지를 대상으로 현존식생 분석 및 식생분포 특성을 파악하여 중장기적인 모니터링 및 관리방안 수립을 위한 기초자료를 제공하고자 수행하였다. 현존식생 조사범위는 훼손지 일대 유역권분포 현황을 고려하여 설정하였으며, 세석평전 조사면적은 55,037㎡, 노고단 조사면적은 166,599㎡ 이었다. 세석평전은 초본층에 의한 식생피복도는 90% 이상 수준으로서 나지노출이 없었고, 관목층의 피복도가 60% 이상으로 안정화되어 있었다. 주요 출현수종은 구상나무, 사스래나무, 쇠물푸레나무, 철쭉, 털진달래, 붉은병꽃나무 등 식재수종과 자연적으로 이입한 자생수종이 생육하고 있었다. 노고단은 신갈나무, 호랑버들, 철쭉, 털진달래, 미역줄나무 등이 우점하는 관목식생지가 52%로 가장 넓게 분포하고 있었고, 전반적으로 식생활착 상태가 양호하였다. 노고단의 원식생은 신갈나무군락으로 추정되었고, 군부대철거지에는 귀화식물이 분포하고 있기 때문에 적극적인 관리가 필요하였다. 연구대상지는 장기적으로 주변 자연식생과 조화로운 식생경관으로 발달할 것으로 예측되었다. 향후 훼손지 복원모델은 인근 지역의 원식생을 고려하여 설정해야 할 것이지만, 복원 달성 목표는 실현가능한 수준의 목표를 설정해야 할 것이다. This study was conducted to provide basic data for mid-to long-term monitoring and establishment of management plans by analyzing the existing vegetation and identifying the vegetation distribution characteristics for the restored vegetation in Nogodan and Seseokpyeongjeon in Jirisan National Park located in the subalpine zone among the independent damaged areas. Actual vegetation survey range was established in consideration of the distribution of the watershed around the damaged area. The surveyed area of Seseokpyeongjeon was 55,037㎡, and the surveyed area of Nogodan was 166,599㎡. In Seseokpyeongjeon, the vegetation coverage by the herbaceous layer was almost 90% or more, there was no bare exposure, and the coverage of the shrub layer was stabilized at 60% or more. The main emerging tree species were planted species such as Abies koreana, Betula ermanii, Fraxinus sieboldiana, Rhododendron schlippenbachii, Rhododendron mucronulatum var. ciliatum, and Weigela florida as well as natively migrated native species. In Nogodan, the shrub vegetation dominated by Quercus mongolica, Salix caprea, Rhododendron schlippenbachii, Rhododendron mucronulatum var. ciliatum, and Tripterygium regelii was the most widely distributed with 52% of the area, and the overall diet was good. The native vegetation of Nogodan was presumed to be a cypress colony. Naturalized plants were distributed in the military base demolition site, so active management was required. The study site was predicted to develop into a vegetation landscape in harmony with the surrounding natural vegetation in the long term. In the future, the restoration model for damaged areas should be set in consideration of the native vegetation of the nearby area, but the goal to achieve restoration should be set at a feasible level.

본 연구는 유아교육현장에서 활용 가능한 교사용 유아 용기 척도의 타당도와 신뢰도를 검증하여 척도를 개발하는데 목적이 있다. 이를 위해 서울시와 경기도에 소재한 유치원 4곳에 재원하고 있는 만 4세와 만 5세 유아 322명을 대상으로 실시하였으며, 문헌고찰 및 자료 수집, 1차 시안 구성, 2차 시안 구성, 예비 검사, 최종 시안구성의 과정을 거쳐 완성하였다. 최종 시안으로 구성된 척도의 타당도와 신뢰도를 검증하고자 SPSS 프로그램을 이용하여 문항양호도 검증, 요인분석, 상관관계, 문항간의 내적합치도를 분석하였다. 먼저, 교사용 유아 용기 척도의 타당도를 분석한 결과, 본 척도의 문항 양호도는 매우 높게 나타났다. 다음으로 구인타당도 검증을 위한 요인분석을 실시한 후, 전체 설명 변량의 41.12%를 차지하고, 부하량이 .50이상인 요인과 문항을 추출하였다. 이에 신체적 용기 12문항, 사회적 용기 12문항, 인지적 용기 6문항, 심리적 용기 6문항의 4개 요인의 36개 문항이 추출되었으며, 전체 용기와 하위요인의 상관관계가 통계적으로 유의미한 것으로 나타났다. 마지막으로 교사용유아 용기 척도의 신뢰도를 분석한 결과, Cronbach ?계수가 .84~.94로 매우 높게 나타났다. 즉, 본 연구에서 개발한 교사용 유아 용기 척도는 타당도와 신뢰도가 양호한 것으로 드러나, 유아교육현장에서 유아교사들이 본 척도를 활용하기에 적합한 척도라고 할 수 있다. This study was conducted to develop a measure of young children’s courage on a teacher’s observation scale. The subjects were 322 young children consisting of 151 four-year-old children and 171 five-year-old children in four different kindergartens located in Seoul and Gyeonggi province. The results of exploratory factor analysis show that thirty-six items from the four factor categories are related to young children’s courage. The four factors are0 ‘physical courage’, ‘social courage’, ‘cognitive courage’ and ‘psychological courage’. In addition, there are significant positive correlations between the sub-area scores and the overall in the young children’s courage scale(r=.12~.83, p<.05, p<.001). The young children’s courage scale has a high reliability: Cronbach α shows .93 overall and .84~.94 for the four factors individually. These results explain that this scale is an appropriate tool for measuring young children’s courage.
