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.

Firefighting hoods protect the head, face, and neck areas of officials while they perform firefighting services. The purpose of this study is to investigate the head size of Korean firefighting officials in order to establish the dimensions necessary to construct firefighting hoods. A total of 98 male firefighting officials participated in this study and 11 body dimensions, necessary for the construction of firefighting hoods, were measured. The data collected from the firefighting officials were compared to the general adult male data from the Size Korea national anthropometric study. The heights, weights, head circumferences, head heights, and bitragion arcs of the firefighters were significantly larger than those of general adult males, which shows that firefighting officials generally have larger body and head sizes than general adult males. Based on the results of Pearson's correlation coefficients, head circumference and head height were judged to be the important measurements for the construction of the firefighting hoods. Thus, these two measurements were chosen as the basic dimensions of the cross tabulation analysis. As a result, head circumferences of 57.00~60.99cm and head heights of 23.00~25.99 cm were found to be important measurement ranges among the firefighters. This study is expected to be used as the basis for the creation of firefighting hoods that help to ensure the safe rescue activities for firefighting officials.

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.

목적 : 본 연구에서는 휠체어럭비 활동에 참여하고 있는 경수손상 환자들과 휠체어럭비 활동에 참여하고 있지 않은 경수손상 환자들을 대상으로 시간사용과 삶의 질을 비교하고자 하였다. 연구방법 : 연구대상자는 총 24명이었고, 이중 휠체어럭비 활동에 참여하고 있는 경수손상환자는 11명이었다. 시 간사용량과 삶의 질을 조사하기 위해 Occupational Questionnaire, 한국판 세계보건기구 삶의 질 척도-단축형을 각각 사용하였다. 결과 : 작업영역별 시간 사용량을 비교한 결과 휠체어럭비 참여군의 여가 시간사용량이 높았고, 전체 작업수행 중요 도와 흥미도, 삶의 질이 높았다(p<.05). 연구대상자들의 일과 여가활동의 수행도, 중요도, 흥미도가 높을수록 시간 사용량도 높았다(p<.05). 결론 : 본 연구의 결과를 통해 경수손상 환자들을 위한 작업치료 중재에 효율적인 시간사용이 포함되어야 하고, 작 업수행 영역의 다양화를 위해 휠체어럭비 활동에 대한 소개와 작업치료에 활용하는 것이 필요함을 제안하였다.
