조경진,조지윤,박인숙,오욱 한국인간·식물·환경학회 2013 인간식물환경학회지 Vol.16 No.6

이 연구는 폐쇄형 식물공장 시스템 내에서 LED 펄스광의 튜티비 및 광도(PPFD)가 상추의 생장 및 광합성률에 미치는 영향을 구명하기 위해 수행하였다. 파종 3주 후 ‘청치마’ 및 ‘청치마’ 실생묘를 bar-type LED(red:blue:white = 5:2:1) 하에서 4주간 생육시켰다. LED 펄스(on/off) 간격은 연속조사(continuous), 200/200μs, 133/266μs, 100/300μs의 4가지로 설정하였는데, 이를 듀티비(duty ratio, DR, 한 주기 대비 점등시간 비율)로 표시하면 각각 100%, 50%, 33%, 25%였다. 이때 광도(PPFD)는 DR 100, 75, 50% 처리에서는 두 수준[고광(high light, HL), 저광(low light, LL)]으로 처리되었고, 광주기는 16시간이었다. 식물공장 내부의 온도는 주야간 20±2ººC, 상대습도는 약 70±10%로 유지되었다. 양액은 온도 20±2ºC, EC는 1.2mS·cm-1, pH는 5.8±0.2로 유지되었고, NFT 방식으로 공급되었다. 처리 4주 후 ‘청치마’ 상추의 생체중과 건물중은 DR 100% HL 하에서 가장 높았고, DR 75% HL 및 DR 50% HL과는 유의차가 없었다. 엽수, 엽면적, 잎 두께(비엽면적의 역수)는 DR 100%, 75%, 50%의 HL처리에서 유의하게 큰 값을 나타내었다. 광이용효율(LUE)은 PPFD에 관계없이 연속광보다 펄스광 처리에서 높게 나타났으며, 특히 DR 25% HL 하에서 가장 높았고, DR 75% HL과 DR 50% HL 처리도 DR 100% HL보다 높은 값을 보였다. ‘적치마’ 상추의 생체중과 건물중은 DR 100% HL 하에서 가장 컸고, DR 100% LL, DR 75% HL, DR 50% HL 하에서 두번째로 컸다. LUE는 ‘청치마’와 같이 연속광보다 펄스광 하에서 높았다. 두 품종의 광합성 속도는 적산 PPFD에 비례하였으며, DR의 효과는 적었다. 결론적으로 펄스광은 상추의 LUE를 높이므로 LED를 광원으로 사용하는 폐쇄형 식물공장의 에너지 절감에 기여할 수 있을 것이다. This study was carried out to examine the effect of duty ratio and intensity of pulsed LED light on growth and photosynthetic rate of lettuce(Lactuca sativa L. ‘Cheongchima’ and ’Jeokchima’) grown in a plant factory system. The three-week old seedlings were grown for 4 weeks under the bar-type LEDs(red:blue:white = 5:2:1) with different LED pulse(on/off) of 400/0(continuous), 300/100, 200/200, 133/266, and 100/300 μs by using oscilloscope during 16 h photoperiod. These indicated duty ratio(DR, percentage of on time from one cycle) of 100, 75, 50, 33, and 25%, respectively. Light intensities were two levels(high and low, HL and LL) at DR 100, 75 and 50%. Air temperature and relative humidity in the system were maintained at 20±2ºC and 70±10%, respectively. Nutrient solution(initial pH 5.8±0.2, EC 1.2 dS·m-1, 20±2ºC) was supplied by nutrient film technique method. In ‘Cheongchima’ lettuce, fresh and dry weights at 4 weeks after treatment were highest in DR 100% HL with no significant difference with DR 75% HL and DR 50% HL. Leaf number, leaf area, and leaf thickness represented by the reciprocal of specific leaf area were largest in plants grown under HL of DR 100%, 75% and 50% for 4 weeks. Light use efficiency(LUE) was higher under pulsed light than continuous light irrespective of PPFD. LUE under DR 25% HL was highest and LUE under DR 75% HL and DR 50% HL was higher than that under DR 100% HL. In ‘Jeokchima’, fresh and dry weights at 4 weeks after treatment were largest under DR 100% HL and second-largest under DR 100% LL, DR 75% HL, and DR 50% HL. LUE in was higher under pulsed light than continuous light similarly to ‘Cheongchima’. Photosynthetic rate was proportionally increased to integrated PPFD rather than DR in both cultivars. These results will be utilized for energy saving in the closed plant factory system using LED as a light source.

For the the enhancement of educational efficiency in on-site training of 3-year health college program, the authors perofrmed a survey. From the survey result the authors came to conclusions as follows, The duration of training in the health college programs should be extended as one year through the extension of length of study. Evaluations in training sites were thought to be unreasonable, and therefore the evaluation system should be improved or newly developed. Educators in colleges are also urged to participate in various workshops to catch the new theory and changing technologies. All health alleges should try to expand their experimental facilities and equipments. Securing suitable training places is very difficult for some colleges located in small cities. At this point the governmental meddling is keenly required to ease the situation. Each training place must prepare its own educational program on which the educators can execute schedules. Training fee is another intricate matter for both collegs and training places. Some criteria for the amount per trainee and proper paying methods should be suggested in the earliest time. Considering the highly sophisticated equipment and higher wages for the manpower within the laboratories and relevanat places, the education in managerial aspects should be included in the programs. To enhance the effiency in the trainings, the student's daily report should be practical one not formalistic, and opportunities to handle the sophisticated equipments should be given to the trainees, and paying the careful consideration to trainees would be desirable.

환경생태정보 전달을 위한 가상·증강현실 사용자 경험디자인 연구 - 서울식물원 온실을 중심으로

조경진,이유미,송영근,정욱주 한국환경복원기술학회 2022 한국환경복원기술학회지 Vol.25 No.2

The purpose of this research is to examine the user experience design that effectively exhibits botanical information through a virtual habitat built with 3D modeling and scanning data for the conservatory at Seoul Botanic Park. Seoul Botanic Park’s conservatory contains environmental and ecological information on the wide spectrum of diverse plants under twelve cities all over the world. However, the exhibition method, which focuses on maps and information boards, has limitations in delivering diverse plant and habitat information to visitors. Virtual and augmented reality can be used as an effective tool for educating and experiencing the contents of various plant species as it can convey the ecological and environmental conditions of the habitat and local culture at diverse levels. This study experimented with constructing virtual habitats using the Unreal Engine and effectively communicating various botanical information through the interaction. With the introduction of a virtual habitat, we intend to enhance the user experience of park visitors and ultimately explore the possibility of using virtual and augmented reality to convey multi-layered environmental and ecological information of landscape.

Reviewing and comparing the certifying systems for clinical laboratory scientists in some developed countries would be meaningful for us in the renovation of our current systems. Through the homepages of relevant organizations in five countries we got the information on education and certifying systems for clinical laboratory scientists. And we also e-mailed or made phone calls directly to the chairpersons for more additional data. The ladders systems in both educational and certifying were well developed in the United States compared to other countries. In Japan and Korea, it seemed that too many competencies are required for the entry-level medical technologist requiring even competencies in the fields of histo-pathology, cytology, clinical physiology in the current medical technologist' s job descriptions. Now we have to evaluate the applicants' competencies at the entry-level and establish the content outlines as a guideline for the applicants. For more reliable and efficient evaluations we might consider adopting the computerized testing like CBT or CAT.

A Study on Family Caregiver Support Programs in the U.S.A.: The Case of the State of Georgia

조경진,김윤정 대한가정학회 2016 International Journal of Human Ecology Vol.17 No.2

This is a descriptive study that introduces programs that support family caregivers looking after the elderly, by focusing on the case of Georgia, in the United States. The U.S. is one of the few countries that support family caregivers by law. In this study, we focus on the evidence-based interventions implemented through the Alzheimer’s Disease Supportive Services Program (ADSSP), a federal policy that complements the National Family Caregiver Support Program (NFCSP). Our findings show that one-on-one evidence-based programs (EBPs) for family caregivers are both economical and effective in assisting caregivers. In our discussion, we highlight how the implementation of the latest EBPs can build an infrastructure to support family caregivers. ADSSP funding is useful as it constructs a caregiver support through the implementation of programs in the local community. The result is the creation of a well-coordinated division of labor among government agencies, academia and NGOs, which produces a synergetic effect in funding, research and development, translation and implementation of programs, and staff training. We conclude that the implementation of EBPs funded by the government is a useful reference for Korea and other rapidly aging countries, if we are to create an infrastructure for caregiver support, which can effectively prevent a crisis in caregiving.
