장미나,김성용,이영진 경상대학교 농업생명과학연구원 2021 농업생명과학연구 Vol.55 No.1

본 연구에서는 경북 지역에 분포하는 소나무림을 대상으로 수관연료의 수직적 구조, 수관연료밀도를 파악하고, 여러 가지 변수를 이용한 수관층 각 부위별 연료량 추정식을 개발하고자 하였다. 본 연구 결과에 의하면, 수관층 연료의 수직적 분포 형태는 방추형으로 상대적 높이 비율 0.6~0.8 구간에 가장 많은 연료가 분포하였으며, 0.4 이하의 수관 하단부에는 주로 고사된 가지가 분포하고 0.8 이상부터 상단부로 갈수록 연료가 적어지는 형태를 보였다. 전체 수관에 대한 연료밀도는 평균 0.38kg/㎥이었으며, 이 중 산불 발생 시 쉽게 탈 수 있는 연소가능한 연료의 밀도는 0.21kg/㎥이었 다. 수관 특성 중 수관길이와 수관폭을 이용하여 수관층 연료량 추정식을 개발한 결과 조정결정계수(R2adj)의 범위는 0.56~0.79이었으며, 수관길이와 수관폭을 변수로 함께 사용하였을 경우 조정결정계수(R2adj)가 더 높은 값을 보였다. 본 연구의 결과는 임목에 대한 산불 연료적 관점에서의 다양한 정보를 제공할 뿐만 아니라, 영상자료를 활용하여 수관층 연료량을 추정하는데 활용될 수 있다. The objective of this study was to analyze vertical structure of crown fuel loads, density of crown fuels and to develop equations using various variables for estimating crown fuel loads of Pinus densiflora S. et Z. in Gyeongbuk province. A total of 30 representative sample trees were felled after considering diameter distribution in Gyeongbuk province and used for this study. The results indicated that vertical distribution of fuels in the crown layers was a spindle shape, with the most fuel loads were distributed between relative height of 0.6 and 0.8 position. Crown bulk density averaged 0.38kg/㎥, of which the density of the available fuels was 0.21kg/㎥. Regression models were developed to estimate of crown fuel loads by using of crown width, crown length and combination of both variables in this study. The R2adj ranged from 0.56 to 0.79 to estimate crown fuel loads. The results of this study will provide valuable information based on the fuel perspective of forest fire and can be used to estimate crown fuel loads using orthophoto imaging data.

장미나,한경혜,Chang. Mina,Han. Gyung-Hae 한국가족학회 2015 가족과 문화 Vol.27 No.2

본 연구의 목적은 맞벌이부부의 일·가족·여가활동 시간의 구조적 차이를 근거로 하여, 부부의 역할분배방식을 유형화 하고, 각 유형별 부부의 일상정서경험의 차이가 존재하는지 여부를 탐색하는 것이다. 이를 위해 본 연구는 어디에서 무엇을 하고 누구와 함께 있는 지로 구성되는 일상의 외적맥락과 그 순간의 느낌이나 생각을 나타내는 내적인 정서경험을 연계해서 살펴보는 경험표집법(ESM)을 활용하였다. 이는 부부들이 직면한 현실 상황에 밀착해서 행위자 스스로가 평가한 경험을 탐색하는 것으로 맞벌이부부의 일상생활을 살펴볼 수 있다는 강점이 있다. 경험표집법을 활용하여, 만 10세 이하의 자녀를 둔 맞벌이부부 총 91쌍,182명 이 하루 6회 총 5일 동안 응답한 자료 5,147개의 자료를 분석한 결과는 다음과 같다. 첫째. 부부 모두 경제활동을 함에도 불구하고, 남편과 아내의 일·가족·여가활동 시간 구조는 어린 자녀를 키우는 맞벌이남녀의 불평등한 생활세계의 모습을 적절히 반영하고 있었다. 둘째. 부부를 분석단위로 하여, 남편과 아내 각각의 시간비율을 기준변수로 하는 군집분석을 실시한 결과, ‘양육중심형’ ‘여가몰입형’ ‘잠재적(양육자,부양자)역할 공유형’ ‘신전통형’의 4가지 역 할분배유형이 도출되었으며, 각 유형 집단은 막내자녀의 연령, 자녀수와 같은 가구 특성에 따라 유의한 차이를 나타냈다. 셋째. 역할분배유형에 따라 맞벌이부부가 일상생활에서 느끼 는 긍정/부정정서 경험은 유형별로 그리고 젠더에 따라 의미 있는 차이를 보였다. 특히 이러 한 차이는 정서차원에 따라 상이하게 나타나, 일상에서 느끼는 긍정정서경험은 부부의 역할 분배 방식에 따라 비교적 큰 차이를 보였던 반면, 부정정서경험은 유형별 차이보다는 젠더차이가 더 강하게 나타났다. 이상의 결과들을 토대로 맞벌이가족이 가지는 다양한 삶의 모습과 경험을 구체적으로 논의해 보았다. The purpose of this study was to cluster the typology of labor division that classified based upon the distribution of work, family and leisure time ratio of husbands and wives among dual-earner couples and to examine the differences in immediate emotional experiences between husbands and wives by the typology. In this study, ninety-one dual earner couples with young children under age 10 participated, and total 5,147 data were collected. It used Experience Sampling Method (ESM), which enables a researcher to assess how people spend their time in daily different settings such as spaces, activities and companions, and how they experience the different settings of their lives. The major research findings are as follows: First, there was a significant difference in daily time pattern and the emotional experiences between husbands and wives. Second, dual-earner couples were clustered into 4 types of division of labor including ‘carer-centered couples’, ‘leisure-oriented couples’, ‘latent dual carer-earner couples’, and ‘modified male breadwinner couples’, based upon the distribution of work, family, and leisure time. Also, there was a significant difference within the 4 types according to household characteristics such as child age, the number of children. Third, the 4 types of division of labor were associated with daily emotional experiences. While positive daily emotional experiences vary depending on the 4 types, negative experiences vary depending on gender. Based on these findings, the significance of division of labor on dual-earner couples’ daily lives is discussed.

The purpose of this study was to investigate preferences and satisfaction levels in maternity and nursing brassiere. A questionnaire was conducted on 302 women from their 20s to 40s who had breastfeeding experience. The questionnaire included questions on participant demographics, purchase behavior, and design preference and satisfaction levels. The majority(98.0%) of the participants had had experience using maternity/nursing brassieres. More than 90% of the participants agreed with the need for maternity/nursing brassieres distinct from regular ones. Shopping online was the most common means of purchasing them. The most and second-most owned fastener types were the detachable shoulder belt type and inside-cup type, respectively. The most selected reason for purchasing or wearing a maternity/nursing brassiere was the convenience of donning and doffing the brassiere during breastfeeding. Participants had lower satisfaction levels with how well maternity/nursing brassieres support and center the breasts, and with the variety of designs available on the market. Respondents indicated that fasteners for breastfeeding should be developed to provide comfort and convenience for breastfeeding. Wearing comfort was reported as the most important factor in purchasing selection, both during the pregnancy and breastfeeding periods. No-wire, back closure, full-cup, U-shape wing, and skin color were the most preferred design styles.

A Comparative Study on Protection Policies for Intangible Cultural Heritages between Korea and China Zhang Mei Na Sungkyunkwan University A fact that culture comes to exert the most important influence in the international society for the cultural century is not new. In particular, It? safe to say that the interest in the intangible cultural heritage is the recently international flow. And, the interest of non-Western countries in the intangible cultural heritage is higher than the Western countries. This study carried out the research on protection policies for intangible cultural heritages of Korea and China, which is multiracial. Korea? protection policy for intangible cultural properties was arranged the legal and institutional foundation as「Cultural Properties Protection Act」had been enacted in 1962. Thus, the protection for intangible cultural properties has been carried out in the national dimension, and now became the advanced level enough for the international society to pay attention. On the other hand, from having joined in ?onvention for the Safeguarding of the Intangible Cultural Heritage?in UNESCO in 2004, China accelerated the protection for the intangible cultural heritage by substituting the intangible cultural heritage for the name of the racial-private culture, which had been included in the existing culture protection law. Korea and China are the countries that are involved in the same Orient, but have mutually different protection background and real situation for intangible cultural heritages. Thus, through this research, it aimed to seek for the better protection policies for the intangible cultural heritages in two countries hereafter by analyzing the protection policies for the intangible cultural heritages in two countries and by grasping the characteristics of the protection policies for the intangible cultural heritages in two countries. This study analyzed the protection policy for the intangible cultural heritages in two countries after examining the present status of protection for the intangible cultural heritages in two countries, which are now being protected in the national dimension, based on the background and formation process of protection for the intangible cultural heritages in Korea and China. The protection policy for the intangible cultural heritage needs to be the one that aims to observe and keep, and to check the spirit of effective preservation and transmission. That is because the protection policy for the intangible cultural heritage should be the base manure as the policy, which can form the excellent spiritual culture in high-dimensional society. The 21st century is the one of culture. Amid globalization in which the restriction to time and space gradually disappears, each country is experiencing the culture war, with already having surpassed the culture competition. It is the so-called era of culture hegemony. In the midst of this flow, it tried to have the opportunity that inspects the protection policies for the intangible cultural heritages in both Korea and China, which show difference while having a close relationship geographically and historically. Especially in light of the reality that this research is not performed much, the more follow-up studies need to perform the deeper comparative analysis. And, this is thought to be capable of contributing not only to the development in own country? culture, but also to the development in world culture by offering new imagination to the global people.

The objectives of this study were to determine and compare the anti-diabetic and anti-inflammatory effects of Antirrhinum majus L. extract (AME) in high fat diet-fed mice (HFD). C57BL/6 mice were assigned to five groups: ND (n=8; normal diet), HFD (n=8), and HFAME [HFD+100 mg/kg AME (n=10), HFD+300 mg/kg AME (n=8), and HFD+600 mg/kg AME (n=10) groups]. Mice were fed their assigned diets for 8 weeks. Mean body weight in the HFD group was 32% higher than in the ND group, but mean body weights in the HFAME groups were unchanged. Mean food efficiency ratio was higher in the HFD group than in ND controls, but significantly lower in HFD+600 mg/kg AME (n=10) groups than in the HFD group. Furthermore, liver, epididymal fat, and subcutaneous fat weights were lower in the HFAME groups than in the HFD group. In addition, mean plasma triglyceride and total cholesterol levels were significantly higher in the HFD group than in the ND group, and lower in the HFAME groups than in the HFD group. Similarly, mean fasting blood glucose was significantly lower in the HFAME groups than in the HFD group. The serum insulin and glucose concentrations were remarkably lower in the HFAME groups than in the HFD group. Insulin sensitivity was measured by glucose tolerance testing (GTT) and insulin tolerance testing (ITT) after animals had been on their respective diets for 6 weeks, and GTT and ITT results in the HFAME groups were significantly lower than in the HFD group. Furthermore, levels of inflammatory cytokines, that is, of monocyte chemoattractant protein-1, interleukin-6, and interleukin-1β, were lower in the HFAME than in the HFD group. In addition, AME prevented HFD-induced increases in the expressions of pro-inflammatory genes in liver, epididymal adipose tissue, subcutaneous fat. AME improved insulin resistance and exhibited anti-diabetic effects in HFD mice. Our findings suggest AME has potential utility for the prevention of nonalcoholic fatty liver disease. 본 연구에서는 고지방식이로 유도된 비만쥐 모델에서 금어초 추출물의 지질대사 개선, 혈당조절, 항염증 효과를 보고자 하였다. 이를 위해 C57BL/6 마우스에서 8주간 금어초 추출물을 경구투여 한 후 임상적 지표로 체중 변화, 장기 무게, 혈중 지질, 혈당, GTT, ITT, 염증 사이토카인, 염증 관련 단백질의 발현 정도를 조사하였다. 그 결과 금어초 추출물은 간, 복부피하지방의 무게를 효과적으로 감소시켰으며, 이는 고지방식이로 인한 비만 개선에 금어초 추출물이 긍정적인 영향을 미치는 것으로 판단된다. 또한 금어초 추출물의 투여는 혈중 중성지방과 총 콜레스테롤 그리고 간세포 손상으로 인한 AST 효소의 혈액 내 유출을 효과적으로 감소시켜 비만상태의 지질대사 이상과 간 손상을 최소화하는 것으로 생각된다. 또한 본 연구에서는 금어초 추출물의 비만으로 인한 혈당조절 장애 개선에 대한 효과를 알아보기 위하여 혈중 글루코오스와 인슐린 농도, 내당능, 인슐린 내성을 확인하였다. 그 결과 금어초 추출물은 유의적으로 혈중 글루코오스 농도를 감소시키고 인위적으로 투입된 글루코오스와 인슐린에 대해서도 혈당 조절 효과를 보였다. 그리고 금어초 추출물이 비만에서 나타나는 만성적인 염증상태에 대한 개선 효과를 알아보고자 하였다. 그 결과 금어초 추출물은 혈액 내 MCP-1, IL-6, IL-1β 등을 효과적 감소시켰으며 조직세포 내 iNOS, COX-2, TNF-α, IL-1β 발현 또한 억제하는 것으로 나타났다. 본 실험의 결과는 금어초 추출물이 비만상태에서 나타나는 고지혈증, 고혈당 그리고 과도한 염증반응을 감소시키고 억제하는 데 유의적인 효과가 있음을 보였다. 이와 같은 금어초의 생리활성은 비만에서 발생되는 각종 질병과 증상에 유익한 식의약소재로 활용 가능성을 보여준다. 더 나아가 이러한 식의약 소재 개발을 위해 심도 있는 반응 메커니즘 구명과 금어초 추출물에 함유되어 있는 기능성 물질 분리 및 동정에 관한 추가적인 연구가 필요할 것으로 판단된다.

뇌전증 아동 부모의 양육스트레스 영향요인 분석

장미나,김희순 한국아동간호학회 2016 Child Health Nursing Research Vol.22 No.3

Purpose: This study was done to explore disease factors in children with epilepsy, parental factors and resource factors that are related to parenting stress and identify effects of each factor on parenting stress. Methods: Participants were 131 parents who had children who visited a hospital or were hospitalized due to epilepsy. Data collection was done between September 17 and November 17, 2012, and self-report surveys were used. Results: In Stepwise multiple regression analysis, factors influencing parenting stress in children with epilepsy were marital communication, educational background of parents, parenting efficacy, children’s development delay, drug treatment and surgical treatment as a method of epilepsy treatment. These factors explained 34.6% (F=13.22, p<.001) of the variance in parenting stress. Conclusion: The findings indicate that parental factors (educational background of parents and parenting efficacy) and resource factors (marital communication) have higher explanatory power than disease factors of the children. Thus, it is importance to assess the capacity of parents through self-evaluation, and to assess barriers to marital communication when developing parenting stress intervention programs. Furthermore, both parents should be involved in interventions for parenting stress.
