건설현장의 주요 작업인 토공사의 경우, 토공 건설장비를 운용하는 개별 작업자에 의해서 작업의 효율성이 좌우되기 때문에 개별 작업자의 숙련도가 전체적인 공사일정에 큰 영향을 미칠 수 있다. 건설현장에는 그 특성상 현장 내 설치된 구조물이나 장비 혹은 움직이는 작업자들이나 장비 등으로 인해 시야가 가려져서 발생하게 되는 비가시 영역이 필연적으로 존재한다. 이와 같은 작업 관련 시각정보의 부재는 작업자가 건설장비를 효율적으로 운용하는데 있어서 결정적인 저해요소가 된다. 증강현실(AR, Augmented Reality)은 현실세계에 가상물체를 중첩시켜 보여주는 컴퓨터 기술이다. 이 기술의 특성을 이용하면 토공사를 수행하는 과정에서의 시각정보 부재 문제를 해결할 수 있고 이를 통한 건설장비의 작업 효율성 향상이 가능하다. 본 연구의 목적은 이러한 토공사에서의 필요 시각정보를 도출하기 위한 작업-시각정보 맵을 제시하고 굴삭기의 작업들 중 AR기술을 적용하기에 적합한 것을 찾아내는 것이다. 연구의 대상이 되는 건설장비는 굴삭기로 한정하였다. 작업-시각정보 맵은 굴삭기 토공작업의 문제점과 그 문제점을 해결하는데 필요한 시각정보를 기반으로 하여 작성되었다. 이 맵으로부터 굴삭기의 작업 효율성을 향상시킬 수 있고, AR기술을 적용하기에도 적합한 4가지 필요 시각정보가 도출되었다. 연구결과를 바탕으로 하여 추후 건설장비 AR 네비게이터 시스템을 더욱 효과적으로 개발할 수 있을 것이라 기대한다. Work efficiency of earth work which is one of the main works occurring in construction site mainly depends on the performance of individual operators of earth work equipment. Consequently, the skill of individual operators of earth work equipment can significantly affect overall construction schedules. Many invisible areas inevitably exist in construction site because of the nature of construction site where occlusions occur from structures being built, installed or moving equipment, moving workers, etc. The lack of visual information regarding tasks critically impedes the effective performance of operators of earth work equipment. AR (Augmented Reality) is a computer technology that superimposes virtual objects onto the real world scene. This characteristic of AR may address the lack of visual informations in earth work process, thus helping to improve the work efficiency of operators of earth work equipment. The purpose of this study is to present a task-visual information map that identifies visual informations required in tasks of earth work and which of the tasks are suitable for AR technology. This study focuses on visual informations in tasks of earth work with excavators. The map was created based on the investigations on the problems of each task of earth work with excavators and visual informations required to address the problems. Through the map, four visual informations were found to be suitable for AR technology to improve the work efficiency of excavator operators. Based on the findings of this study, AR systems for excavators can be developed more effectively.

송수진 ( Su-jin Song ),장경수 ( Kyoung-soo Jang ),황인채 ( In-chae Hwang ),안기완 ( Ki-wan An ),이계한 ( Kye-han Lee ) 한국임학회 2016 한국산림과학회지 Vol.105 No.3

본 연구는 소나무림의 간벌에 따른 임분의 바이오매스 변화, 토양 CO₂ 발생량, 낙엽 및 뿌리의 분해율을 조사하여 연간 탄소 동태를 파악하고자 수행되었다. 8년생 소나무 묘포장에 대조구, 간벌지(50%), 개벌지를 각 3 방형구씩 조성하였고, 나지는 한 방형구를 조성하였다. 측정은 2012년 3월부터 2014년 2월까지 이뤄졌다. 연평균 근원직경 증가는 대조구 0.89 cm, 간벌지 1.48 cm로 대조구보다 간벌지에서 컸다(p<0.05). 연평균 순생산량은 대조구 5.17 kg C m^­2 yr^­1, 간벌지 4.85 kg C m^-2 yr^-1로 나타났다. 연간 토양 CO₂ 발생량은 대조구, 간벌지, 개벌지, 나지에서 각각 3.71, 3.90, 4.17, 4.56 kg CO₂ m^-2 yr^-1으로 식생의 제거는 토양 CO₂ 발생을 증가시켰다(P<0.05). 토양 CO₂발생은 토양온도와 양의 상관관계가 있으나 토양수분과는 뚜렷한 관계가 나타나지 않았다. 순생태계생산량(NEP)은 대조구 1.57 kg C m^-2 yr^-1, 간벌지 1.36 kg C m^-2 yr^-1, 개벌지 -0.67 kg C m^-2 yr^-1, 나지 -1.25 kg C m^-2 yr^-1으로, 식생 유무에 따른 차이를 나타냈다(P<0.05). 간벌은 임분 내 개체목의 근원직경과 탄소량을 증가시켰고, 1년 후 간벌재로 반출 된 탄소량의 86%를 회복했다. 또한 토양 CO₂ 발생량을 증가시켰고, 순생태계생산량을 증가시켰다. 소규모의 연구임에도 불구하고, 본 연구의 결과는 간벌에 의한 임분 밀도 조절이 소나무 유령림의 탄소저장량 증대와 생장에 있어 효과적임을 보여 주었다. 이는 우리나라에서 기후변화 완화를 위한 적극적인 소나무림의 경영이 필요함을 시사한다. 추후 실제 소나무림에서 영급별, 간벌 강도별, 지위별 등 다양한 변수를 고려한 장기적 연구가 수행되어야 할 것이다. The objective of this study was to examine carbon dynamics with biomass, soil CO₂ efflux, litter and root decomposition after tree density control in young Pinus densiflora stands. The stands were established with 50% thinning, clear-cut, and control stands with three pseudo-replicated plots and a bare soil plot in 8-year-old Pinus densiflora nursery field. Monthly measurements were conducted from March 2012 to February 2014 and aboveground biomass and coarse-roots were estimated by derived allometric equations. Average diameter growth at root collar in control and thinned was 0.89 cm and 1.48 cm per year, respectively, and the diameter growth of control stand was significantly higher than that of thinned stands (p<0.05). Total biomass was estimated to 5.17, 4.85 kg C m^-2 per year in control and thinned, respectively. Annual soil CO₂ efflux in control, thinned, clear cut, and bare soil was 3.71, 3.90, 4.17, 4.56 kg CO₂ m^-2 yr^-1, respectively and removing trees significantly increased soil CO₂ efflux (p<0.05). Net Ecosystem Production (NEP) was 1.57, 1.36, -0.67, -1.25 kg C m^-2 yr^-1 in control, thinned, clear cut and bare soil in the young Pinus densiflora stands. NEP was significantly decreased by removing trees. Thinning increased diameter at root collar and carbon of individual tree and recovered 86% of carbon removed by thinning after one-year. In addition, soil CO₂ efflux increased and NEP increased by thinning. Results of this study, tree density control such as thinning increased the carbon storage and growth of the young Pinus densiflora stands.

가정에 대한 교육적 성찰

This study aims to review the nature of the family based on the traditional perspective of Confucianism. This article is also to clarify an opinion that the traditional perspective of Confucianism is the cause of the recent conflict and crack over the home recently. That is a misunderstanding. Rather the traditional role of family, before demonstrating its educational power, was undergoing fragmentation and distortion after modern times. Unlike home whilst discourse, home does not stop in place, providing support to activities outside the home to relax and recharge. Especially based on the Yulgok’s viewpoint, parents and children are the party that is responsible for their personality and that supported the Saramdaum of the other. Home, which is not a place for individuals, has the public duty to be extended learning and practice of Saramdaum a home outside the community. ‘Family’ was already inherent in education to seek a decent life. 'Family education' and the word of derivatives related thereto demonstrate the role of the family has not been the focal point for education after modern times. This study is able to offer an implication for the families losing their original purpose in the present time that school is only apparently advocating the learning and practice to Saramdaum. 이 글은 전통 유학적 관점에서 가정의 본질을 검토하는 데에 목적이 있다. 또한 유교 사상에 근거한 전통적 가정관이 가정을 둘러싼 끊이지 않은 균열과 갈등의 원인으로 작용한다는 일부의 시각에 대한 해명이기도 하다. 문제는 가정이 자체적으로 가진 교육적 동력을 채 발휘하기도 전에 근대 이후 왜곡·분열했음을 직시하지 못하는 데에 있다. 근대 이후 가정은 사람다움을 향한 배움과 무관하였다. 단지 휴식 및 재충전을 위한 장소, 가정 밖의 활동들을 지원·보조하는 역할에 충실했다. 그러나 율곡의 견해에 따르면, 부모와 자녀는 각자의 인격을 책임지는 자이며 서로의 사람다움을 지지해주는 관계이다. 가정은 개개인의 사적인 공간에 머물지 않고, 사람다움에 대한 배움과 실천을 가정 밖 공동체로 확장시켜야 할 공적 책무를 지닌다. 따라서 ‘가 정’은 이미 그 자체에 사람다움을 추구하는 교육이 전제되어 있다. 근대 이후 ‘가정 교육’이란 단어와 관련 정책들이 강조될수록, 가정이 더 이상 배움의 구심점 역할을 하지 못하는 상황을 드러낸다고 볼 수 있다. 이는 오늘날 학교가 사람다움을 향한 배움과 실천을 겉으로만 표방하는 상황임에도 불구하고, 학교·사회에 밀려 본연의 책무마저 상실한 가정에 대해 하나의 시사 점을 제시할 수 있을 것이다.

조선시대 자녀교육의 한 사례: 윤증의「여자행교(與子行敎)」를 중심으로

송수진 ( Su Jin Song ) 한국교육사학회 2014 한국교육사학 Vol.36 No.3

명재 윤증(明齋 尹拯, 1629~1714)은 조선 후기 유학자이자 소론의 영수였다. 윤증은 내실(內實)과 내수(內修)에 힘써 실심(實心)의 함양을 추구하였다고 평가 받는다. 윤증이 36년 동안 맏아들 윤행교와 주고 받은 편지인 「여자행교」는 어떻게 하면 선비로서 배움을 제대로 이해하고 실천하며 살아갈 것인가에 관한 구체적 방법을 이야기하고 있다. 이는 처세에 관한 조언에서 그치는 것이 아니라, 학자 윤증이 성취한 공부의 전승이다. 「여자행교」는 선비로서 추구해야 할 공부의 지향, 범위, 방법 등을 망라하고 있다. 공부란 일상 생활에서 언제나 마음을 삼가고(謹), 절제하며(愼), 경(敬)을 지니려는 노력이다. 윤증은 이 과정에서 리기심성 등의 성리학 개념들을 불필요하게 여기거나 부정하지 않았다. 이론을 충실히 실천하기 위해 성리학 이론을 정확히 음미하는 공부를 강조하였다. 공부가 제대로 이루어진다면 가정과 사회에서 발생하는 문제들을 조화롭게 해결할 수 있어야 했다. 결국 윤증의 자녀교육 사례는 조선 중기 이후 가정 내에서 유학 이념이 비형식적으로 학습되는 과정과 개인의 공부가 사회구성원의 감화로 확장되는 과정을 보여준다. 윤증의 자녀교육은 평생 선비를 지향하던 그의 삶을 그대로 반영하였다. 지행일치의 삶이 있기에 자식에게 감화력 있는 가르침을 행할 수 있었다. 윤증의 자녀교육 사례는 오늘날 가정교육의 부재, 특히 아버지 역할 부재의 현실에서 가정교육 지향점의 단서를 제공할 것이다. This study aims at exploring the teaching of Meong Jae Yun jeung, a scholar and a politician of late Jo Seon Dynasty, to his elder son Yun Haeng Kyo. Yun jeung and Yun Haeng Kyo had a great deal of correspondence for 36 years. Their letters were collected and published with a title of「YeoJaHaengKyo」, which is examined for this study. Yun jeung was the teacher as well as the father of Yun Haeng Kyo. His teaching to his elder son Yun Haeng Kyo had unchanged at all over the years, with a very strict morality. Main point of his teaching was cultivating mind (心工夫). Yun jeung directed his son to keep the identity of a scholar(士) throughout the self cultivation which included controlling mind(謹), alert(愼), and keep Kyeong(敬) in everyday life. The teaching of Yun jeung pointed out self-discipline as a scholar as well as a local officer. Yun jeung had no experience as an officer in his life, but projected his academical ideals onto his son. With his teaching, Yun Haeng Kyo tried to stick to the basics of Confucianism on his life as an officer. Based on the teaching of Yun jeung with the unity of knowledge and life, Yun Haeng Kyo kept reminding himself as a scholar for his life. This point gives us an implication for the present that father’s role as a mentor is minimized.

Objectives: This study, aims to examine the distribution characteristics of asbestos-containing building materials; risk assessment and area of distribution of asbestos-containing building materials depending on year of construction; building materials; types of building materials; and usage in public buildings in order to create fundamental data for safe management of public buildings. Methods: The asbestos investigation was conducted by an asbestos research institution from March to May 2014, targeting 41 public buildings which were subject to asbestos investigation in South Chungcheong-do Province. With respect to 381 presumed asbestos-containing materials, an investigation was conducted into whether they contained asbestos, asbestos type, content, year of construction, and use in the building were examined, and a risk assessment was performed. Results: Asbestos-containing building materials were used in 35 buildings(85.4%). Among them, 31(88.6%) were public buildings. Asbestos was detected in 73% of 381 suspected asbestos-containing materials, which were mostly ceiling materials (85.2%). The older the buildings, the more they showed a tendency to have a significantly higher risk assessment score. The ratio of average area with asbestos-containing building materials to total floor area was 57.6%, 44.1%, and 17.8% for buildings built in the 1980s, 1990s, and 2000s, respectively. This showed a tendency to be significantly higher with the age of the building. Conclusions: From the results above, it can be concluded that with the age of the buildings, the risk assessment score and the ratio of average area with asbestos-containing building materials to total floor area became significantly higher. Given the concern about the exposure to asbestos of residents and civil petitioners, safety management of older public buildings and measures for dismantling and removal of asbestos-containing building materials should therefore be urgently established.

A handbag is an important factor for contemporary fashion. Besides the functional aspect, it enables to make the dress-up better and represents the personality of wearer. However, today, the handbag accompanied with Hanbok is uniform. The purpose of this paper is to identify the trend about what pattern of handbags for Hanbok has been used since the use of handbag has been spreaded in our country, in order to develop various designs of handbags for Hanbok. The target of this study is a handbag used by Korean women for Hanbok, a traditional costume of Korea. The period is limited from 1920"s before 2000 and the handbags shown in the journals for women or newspaper that was published in this time were analyzed. The handbags, imported at the beginning of 20th century were selected for the taste of purpose of users without dividing them for Western clothing or Hanbok. In 1920"s, the vanity case or opera bag was popular and in 1930"s, beads bags were popular. From the end of 1930"s to 1945, the development of handbag was very tenuous because people were on the war basis. After Korean War in 1950, the handbag with handle was popular. Till that time, handbag was used without division for Hanbok and Western clothing and a small and not-angled handbag used to be recommended for Hanbok. By the 1960"s, the handbag only for Hanbok began to appear which led to the division of handbag for Hanbok and Western clothing. A pouch style handbag, color-matched with Hanbok appeared for the first time. But the beads bag was still popular. Such trend continues to 1970"s. By the 1980"s, people became to wear Hanbok as a formal dress not a everyday dress and the division of handbag for Hanbok and Western clothing was identified clearly. At this time, as a handbag for Hanbok, a clutch bag with metal frame, covered with same fabric as Hanbok appeared newly and led fashion trend until 1990"s.

한국인 상용 식품의 혈당지수 (Glycemic Index) 추정치를 활용한 한국 성인의 식사혈당지수 산출

송수진(Song SuJin),최하늬(Choi Hanui),이사야(Lee Saya),박정민(Park Jeong-min),김보라(Kim Bo Ra),백희영(Paik Hee-Young),송윤주(Song YoonJu) 한국영양학회 2012 Journal of Nutrition and Health Vol.45 No.1

Recent studies have reported that the glycemic index (GI) has an effect on developing the risk for metabolic abnormalities such as diabetes, dyslipidemia, and obesity. As there are no reliable GI values for common Korean foods, only a few studies have been carried out using the dietary GI for Korean adults. The aim of this study was to establish a table of GI values for common Korean foods and evaluate dietary glycemic index (DGI) and dietary glycemic load (DGL) among the Korean adult population. International tables of GI values and other published values were used to tabulate GI values for common Korean foods. Among 653 food items, 149 (22.8%) were adapted from published data, 60 (9.2%) were imputed from similar foods, and 444 (68.0%) were assigned a zero. Data from 7,940 subjects aged 20 years and older in the 2007-2008 Korea National Health and Nutrition Examination Survey were obtained, and DGI and DGL were calculated. The average DGI was 60.0 and the average DGL was 182.5 when the reference food GI value was glucose. After adjusting for potential confounding variables, DGI and DGL increased significantly according to age group (p for trend < 0.001). The food group that contributed most to DGL was grain and its products supplying 85.3% of total DGL, whereas the mean GI value in grain and its products was 72.6. Fruits and potatoes also contributed to DGL (5.8 and 2.9%, respectively), and their GIs were high (67.7 for potatoes and 45.8 for fruits). For individual food items, white rice supplied 66.7% of total GI followed by glutinous rice (2.3%) and steamed white rice cakes (2.0%). In conclusion, a table of GI values for 653 common food items was established in which white rice was the most contributing item to DGL. Our results will be useful to examine the relationships between DGI, DGL, and metabolic abnormalities in the Korean population.
