The amount of formaldehyde removal by indoor pot plants was assessed in actual space, and compared with removal amount calculated from a sealed chamber test. Epipremnum aureum, Rosmarinus officinalis, and Gardenia jasminoide were placed in a room, occupying 3, 6, and 9% of the room volume, respectively. When each species occupied 3, 6, and 9% of the room volume, formaldehyde was removed by 30.9, 47.7, and 67.0%, and the relative humidity increased by 4.8, 8.3, and 10.0%, respectively. When pot plants occupied 1% of the room’s volume, formaldehyde was decreased by 6-7% in the room. A small difference in the rate of formaldehyde removal was observed among the species. The ratio of the formaldehyde removal measured in the room over the its theoretical removal calculated as the chamber test was found to be 0.05, approximately 20 folds. As a result, it has been found that indoor plants could be an effective method for the purifying of indoor air, according to the results suggesting that pot plants occupying about 1% of the room’s volume reduced formaldehyde by approximately 7%.
A New White Spray Carnation (Dianthus caryophyllus) Cultivar, “Dreambyul”
김광진,정향영,최성렬,신학기,Oh Keun Kwon, 한국육종학회 2006 한국육종학회지 Vol.38 No.5
Dianthus caryophyllus “Dreambyul” was selected from the progenies of a cross “Zenga” and “Euge-nia” in 1999 at the National Horticultural Research Institute, Rural Development Administration. It was finally selected in 2002raytype. It has white with pink edge flower color. The flower color is particularly beautiful in indoor. It has a long vase life and mod-erately resistance against Fusarium oxysporum. It is grown over 8oC at night and under 25oC at day. The cultivar was applied for avariety protection 2002 and was released to the growers and commercialized in 2003.

Dianthus caryophyllus “Garnet” was selected from the progenies of a cross “Master” and “97007-2”in 1998 at the National Horticultural Research Institute, Rural Development Administration. It was finally selected in 2001 afteranddeveloped as a substitute for “Desio”. “Garnet” has shorter days to flower than “Desio”, also moderately resistance against Fusar-ium oxysporum. Optimum temperature for its growth are over 8oC at night and under 25oC at day. The cultivar had been appliedfor a variety protection in 2001 and was released to the growers and comercialized in 2002.

실을 이용한 안면부 및 목의 거상술 (Won V Lift)
김광진,박원진 대한미용성형외과학회 2012 Archives of Aesthetic Plastic Surgery Vol.18 No.3
During the facial aging, a series of physical and biochemical changes leads to tissue hypotrpphy,sagging and wrinkles not only at the level of the skin but also in the soft tissue structure. There has been a recent trend toward minimally invasive procedures for facial rejuvenation. This trend is keeping with a general demand toward more effective procedure with less tissue injury and less down time for the patient. Suspending thread technique is a new innovation in plastic surgery. Fifty patients underwent a threadlift procedure in combination with fat injection or filler injection to the midface, lowface, jowl and neck. We used anchoring point with deep temporal fascia in cheek and low face lift and mastoid fascia in neck lift without any incision. The procedure outcome was assessed in each case through patient interviews. All patients demonstrated improvement and youthful appearance in the midface, lowface, jowl and neck with minimal complications. Threadlift is a safe procedure with limited scarring, rapid recovery and low complication rates. The combination of the threadlift and fat injection or filler injection enables the increase of volume of mid or low face and prevents the complication with great patient satisfaction.

본 논문에서는 대표적인 이동 로봇의 장애물 회피 방법들의 성능을 분석한다. 이를 위해 장애물 회피 성능 지수로서 목표점까지 이동한 거리, 이동 시간, 장애물과의 거리, 로봇 동작의 평활도(smoothness)를 제시한다. 특히 로봇 동작의 평활도는 로봇 동작 시 조향 방향의 각가속도와 저크(jerk)를 사용하여 로봇의 실질적 이동 효율성을 측정하는 성능 지수이다. 주어진 성능 지수에 의하여 4가지의 주요한 장애물 회피 방법을 비교하였다. 주요한 장애물 회피 방법은 인공 전위계 방법, 탄성력(elastic force) 방법, 가상 거리(virtual distance)에 의한 인공전위계 방법, 그리고 가상 거리에 의한 탄성력 방법이다. 시뮬레이션을 통하여 각 방법의 성능을 비교 분석하여 각각의 장애물 회피 특성을 파악하였다. This paper analyzes performance of major obstacle avoidance methods. For the analysis, numerical performance indexes are proposed: motion distance to goal point, motion time, distance to obstacles, and smoothness of the motion. Especially, the index of smoothness measures efficiency of the motion using the angular acceleration and jerk of the robot heading. Four major obstacle avoidance methods are compared in terms of the performance indexes. The four methods are artificial potential field(APF) method, elastic force(EF) method, APF with virtual distance, and EF with virtual distance. Through simulation, the four methods are compared and features of the methods are explored.
