This study aims to examine the moderating effect of Extended Song Sharing for helping alcoholics to deal with stress. ESS is structure with non-verbal techniques approaches traditional Song Sharing technique. For this study, 64 alcoholics hospitalized were experimental (n=33) and control groups (n=31). The group was asked to participate in 12 ESS programs twice a week, every 45 minutes for six weeks. During this period, all those who belonged to the experimental and control groups were required to continue to participate in treatment programs prescribed by hospitals. Result: ESS interventional effects on subjects were evaluated using a stress response scale. As a result of the experiment, the WCC score of the experimental group increased 7.3% (p=0.000) but there was almost no change in the control group (1.5% increase, p=0.019). Effects of WCC types were higher in the experimental group, followed by 13.67% (p=0.006) in coping with wishful thinking, 9.66% (p=0.000) in the pursuit of social support, 6.35% (p=0.000) in dealing with problems, and 4% (p=0.000) in coping with emotions. ESS activities have been confirmed to improve the way alcoholics cope with stress.

As the residence time in the vehicle increases, the passenger desires a pleasant and stable riding environment in addition to the high driving performance of the vehicle. The windshield defrosting performance is one of the performance requirements that is essential for driver's safe driving. In order to improve the defrosting performance of the windshield of a vehicle, relevant elements such as the shape of the defrost nozzle should be appropriately designed. In this paper, CFD based numerical analysis is conducted to improve defrost performance of small electric vehicles. The defrost performance analysis was performed by changing the angle of the defrost nozzle and the guide vane that spray hot air to the windshield of the vehicle. Numerical simulation results show that the defrosting performance is best when the defrost nozzle angle is $70^{\circ}$ and the guide vane installation angle is $60^{\circ}$. Based on the analytical results, the defrosting experiment was performed by fabricating the defrost nozzle and the guide vane. As a result of the experiment, it is confirmed that the frost of windshield is removed by 80% within 20 minutes, and it is judged that the defrost performance satisfying the FVMSS 103 specification is secured.

This study analyzed the post-exercise cardiopulmonary function, maximal oxygen uptake, heart rate and recovery time through smoker's short - term smoking cessation and trunk stabilization exercise for 72 hours. We analyzed the effect of trunk stabilization exercise on the cardiopulmonary function of smokers and non-smokers. As a result, it was found that both smokers and non-smokers groups showed significant changes in pulmonary function (FVC, SVV, MVV), maximal oxygen uptake, recovery time Difference. This suggests that the trunk stabilization exercise may have a positive effect on the cardiopulmonary function of short-term non-smokers as well as non-smokers for a short period of time, and a more stable and effective method for preventing and improving the reduction of cardiorespiratory function

In this study, we developed education materials using history of science related to the experiment of 'Boyle's air pump' and the Boyle and Hobbs' debate of vacuum to find out the perceptions of NOS by pre-service chemistry teachers. For the study, 29 pre-service chemistry teachers at a college of education in Chungcheongbuk-do were selected. As RFN items that were related to the contextual situation developed in this study, items in the categories of 'Aims and Values', 'Scientific practices', 'Scientific Methods among Educational Applications' and 'Social-Institutional Aspects among Educational Applications' were selected. Through the items of RFN, the perceptions of pre-service teachers in non-contextual situations were investigated. Then we presented the pre-service teachers with the situation related to Boyle's experiment on air pump and Boyle and Hobbes' debate over vacuum. In addition, their perception of NOS was examined in contextual situations related to RFN items. Responses to the items, experimental results related to Boyle's Law, group discussion, and interview data were collected as data. As a result of the study, it was found that pre-service teachers had informed perceptions in most of the items, but cases with naive views or mixed views were found in context experimental situations. This study can contribute to the NOS education for pre-service chemistry teachers by development of context situation education materials related to NOS and by finding out their perceptions in the non-contextual and contextual situation.

Amorphophallus paeoniifolius (Dennst.) Nicolson는 영명으로 Elephant yam 또는 Whitespot giant arum 으로 불리는 천남성과(Araceae) 식물로 동아시아, 뉴기니, 오세아니아, 마다가스카르 등지에서 자생하고 있으며 숲의 가장자리 또는 2차림에서 발견 된다. 다년생 식물로 덩이줄기는 어두운 갈색의 둥근모양으로 직경 20~25 cm로 자라고 수염뿌리가 사방으로 달린다. IUCN 적색목록(Red List)에 관심대상 종(LC: Least Concern)에 속하는 식물이다. 현지인들은 마(Dioscorea Polystachya Turcz.)처럼 채소로 먹기도 하며 약용으로 쓰이기도 하는데 복부장애, 소화불량, 천식, 기관지염, 빈혈 등에 약효가 있다. Amorphophallus paeoniifolius은 $25^{\circ}C{\sim}35^{\circ}C$, 연강수량 1,000~1,500 mm에서 잘 자란다. 가운데 눈이 올라오면서 생장을 시작하고 며칠이 지나서야 잎 또는 꽃으로 자라는지 알 수 있다. 잎의 생육주기는 잎눈이 생장을 시작하면 잎자루 끝에 소엽과 소잎자루가 접힌 채로 올라온다. 소엽들이 펴지면서 완전한 모습을 갖추는데 30일 이상의 생장기간을 갖는다. 잎의 형태는 우상복엽(pinnate compound leaf)으로 우산처럼 보이는 잎 하나로 광합성을 한다. 잎은 최대 높이 2.5~3 m, 너비 3 m까지 자라며, 잎자루의 색은 녹색과 청색으로 얼룩덜룩한 무늬가 있다. 인공환경 조건에서 Amorphophallus paeoniifolius 생활사 중 잎의 주기를 연구하기 위해서 광, 온도 등의 지상부 환경은 열대 및 아열대 식물의 자생지와 유사하게 조성하였고, 지하부 환경은 인공 배합토를 사용하여 조성하였다. 평균온도는 $25{\sim}28^{\circ}C$, 겨울철 최저 $16^{\circ}C$, 여름철 최고 $33^{\circ}C$를 유지 관리 하였다. 자동 환경제어시스템으로 온도 및 환기를 유지 관리하고 필요에 따라 수동제어 관리를 병행하여 조절하였다. Amorphophallus paeoniifolius는 잎을 먼저 생성하고 광합성으로 생산된 영양물질을 덩이뿌리에 저장을 하고 그 영양물질을 이용하여 꽃을 피우는 생육 특성을 지닌다. 실험에 사용된 공시 식물은 2018년 12월 미얀마에서 생체(덩이줄기) 형태로 도입되었다. 화분에 식재 후 약 5개월이 지난 시점에서 잎의 생장이 시작되었다. 2019년 7월 29일 기준으로 높이 80 cm, 너비 60 cm의 크기로 성장하였으며, 생육환경에 따라 3~5개월 뒤 잎이 지고 나면 다시 덩이줄기로 되돌아갈 것으로 판단된다. 하지만 지금까지 이 식물에 알려진 정보는 인공환경에서의 연구가 아닌 자연환경에서의 연구결과이기 때문에 인공적인 온실 환경에서 자란 Amorphophallus paeoniifolius는 잎의 주기는 더 오래 갈 수도 있으며 꽃의 주기 또한 느리거나 빠를 수 있다. 잎의 생장주기(Leaf Cycle)시 잎자루가 낮과 밤의 방향을 달리 하여 자라는 것이 관찰되었다. 이는 광합성을 위해서 잎자루의 방향을 햇빛 방향으로 돌리는 것으로 판단된다. Amorphophallus paeoniifolius를 실내 조경 식물 또는 식 약용의 소재식물로 활용하기 위해서는 꽃의 생장주기 등 추가적인 모니터링과 연구가 필요하다.

The purpose of this study is to analyze the effect of the height and insole height upon landing on the lower limb joint angle and muscle activity during maximum ground repulsion in young men. For a male in their twenties, a landing motion was performed with a force plate on a 40cm-high platform by wearing one of 0, 3, 5cm polyurethane insoles per week for a total of 3 weeks. During the landing motion, the joint angle of the lower extremities and the muscle activity of the rectus femoris, biceps femoris, anterior tibialis and calf muscles were measured during the maximum ground repulsion. In order to compare the changes in the joint angle and muscle activity of the lower limbs according to the height of the insole, a one-way ANOVA with repetitive factors was performed. As a result of the analysis of the lower limb joint angle, the higher the height of the insole affected the angle of the left ankle joint. As a result of the muscle activity analysis, the higher the height of the insole affected the right anterior tibialis muscle and biceps femoris. It is thought that it is possible to protect the body when landing through sufficient muscle strength increase of the lower limb muscles. As the angle of the affected muscle and lower limb joint may be different depending on the type of insole, it is considered necessary to study it.

Citizen participation and Living Lab are attracting interest as one of the major strategies for the success of smart cities. In a Living Lab, citizens, who are the end-users of technology, participate in the search for alternatives to define and solve problems and repeat experiments to verify alternatives in a circular process. The purpose of this research was to present an operating model of a citizen-participating online community platform to improve urban problems, implement and test it, and show its applicability. To this end, an operation model of a citizen-participating online community platform was proposed to improve urban problems. An online platform was designed and implemented to reflect the functions pursued by the operation model. Finally, a pilot test for the function was performed using the Oma Elementary School case located in Ilsan, Goyang-si, Gyeonggi-do. The operating model was designed with the city's pedestrian environment and children. As a result, the sharing and communicating process of urban issues among community members worked appropriately according to the designed intention. The Living Lab coordinator could visualize and view urban issues posted by users on a map based on location information. Visualizing the urban problem as a heat map confirmed that urban problems were concentrated in a specific area.
