본 실험은 광 환경이 자생 Veronica속 4종 구와꼬리풀, 봉래꼬리풀, 부산꼬리풀, 큰구와꼬리풀의 생장 및 개화에 미치는 영향을 구명하기 위해 실시하였다. 이중 봉래꼬리풀은 희귀 및 특산식물로 지정되어 있는 우리나라의 자생식물이며 부산꼬리풀은 우리나라에서도 부산지역에서만 자생하는 특산식물이자 자료부족종으로 분류된다. 실험은 2018년 3월 30일부 터 2018년 8월 17일까지 수행되었으며 Veronica속 4종을 0, 40, 60, 90% 차광환경에서 재배하였다. 구와꼬리풀을 0~60% 차광환경에서 재배시 90% 차광환경에서 재배한 개체보다 지상부의 생체중이 무겁고 엽수 및 가지수가 많아 생장이 유의하게 좋았다. 큰구와꼬리풀의 줄기 두께는 90% 차광환경에서 재배시 유의하게 얇아져 생장이 불량하였다. 구와꼬리풀과 큰구와꼬리풀은 0~60% 환경에서 재배시 모든 개체가 개화하였으며 90% 차광환경에서 재배한 개체보다 개화소요일수가 짧 아졌다. 봉래꼬리풀은 0~40% 차광환경에서 재배시 60~90% 차광환경에서 재배한 개체보다 지상부 및 건물증이 유의하게 증가하여 생육이 좋았으며, 관상가치 측면에서 가장 높은 점수를 받았다. 부산꼬리풀의 관상가치는 0, 40, 60, 90% 차광환경에서 재배시 각각 4.0, 3.0, 2.2, 1.0점으로 조사되어 동일한 Veronica속이라도 종에 따라서 광 민감도가 다양한 것을 확인하였다.

본 실험은 저온처리 기간과 일장이 자생 돌마타리의 휴면타파와 생장 및 개화에 미치는 영향을 구명하기 위해 실시되었다. 노지에서 재배중인 돌마타리의 생물계절현상 반응(phenology) 을 3월부터 10월까지 조사하였다. 또한 저온처리 기간이 돌마타리 휴면타파 및 개화에 미치는 영향을 알아보기 위해 4°C 저온에 0, 3, 6, 9, 12주간 처리한 후 장일환경(16h), 25°C 온도조건에서 재배하면서 생육특성을 관찰하였다. 일장이 돌마타리의 생육 및 개화에 미치는 영향을 알아보기 위해 자연저온 처리된 돌마타리를 단일(9h), 중일(12h), 장일조건(16h)에서 재배하여 생육 특성을 관찰하였다. 야외에서 재배중인 돌마타리는 늦여름인 8월부터 9월까지 개화하는 특성을 보였다. 저온처리 기간에 따른 실험결과 9, 12주 저온처리를 받은 식물이 3, 6주간 저온처리 한 식물에 비해 개화소요일수가 유의하게 단축되었다. 돌마타리는 4°C 온도에서 9주 이상 처리시 33%의 개화율을 보이는 것으로 조사되었다. 일장에 따른 실험결과, 장일환경에서 재배된 돌마타리의 초장은 50.1cm였으나 단일 및 중일환경에서 재배된 식물의 초장은 각각 16.7, 16.1cm로 조사되었다. 돌마타리는 장일환경에서 16주간 재배 시 100% 개화하였으나 단일 및 중일 환경에서 재배 시 전혀 개화하지 않았다. 결론적으로 돌마타리 는 휴면타파 및 개화를 위해 저온을 필수적으로 요구하며 장일 환경조건에서만 개화하는 질적장일식물임을 확인하였다.

Photosynthetic characteristics and growth responses of Phalaenopsis Queen Beer ‘Mantefon’ orchid were determined in plants exposed to variable carbon dioxide (CO2) concentrations at 2-, 24-, and 36-weeks age (i.e., corresponding to juvenile, young, and mature vegetative growth stages, respectively). Plants were grown at 400 (control), 800, or 1,600 μmol･mol-1 CO2 for 6 hours during the nighttime for 32 weeks. Phalaenopsis ‘Mantefon’ in 2- and 24-week-old plants grown at 1,600 μmol･mol-1 CO2 had increased leaf number and net CO2 uptake compared with the plants grown at 400 μmol･mol-1 CO2. In 36-week-old of Phalaenopsis ‘Mantefon’, leaf number was significantly greater in plant grown at 800 and 1,600 μmol･mol-1 conditions compared with plants grown at 400 μmol･mol-1 CO2. Leaves that emerged after the start of the CO2 treatment were initially longer in the plants grown at 1,600 μmol･mol-1 CO2 than at 400 μmol·mol-1 C O2, but the final leaf length was shortest in the plants grown at 1,600 μmol･mol-1 CO2 condition. Plants showed crassulancean acid metabolism characteristic of nighttime CO2 uptake regardless plant growth stages. We found that growers may be able to promote leaf growth with increasing leaf number and reducing time to leaf initiation in the 36-week-old (i.e., mature stage) plants with 800 – 1,600 μmol·mol-1 CO2 and 2- and 24-week-old (i.e., juvenile and young stages) plants with 1,600 μmol·mol-1 C O2 for Phalaenopsis ‘Mantefon’.

The purpose of this paper was to investigate the comparison of balance and muscle strength between dominant and non-dominant legs in adults. Thirty adults in their 20s participated in this study. The dominant and non-dominant legs were selected based on the dominant hands of the target. The subject's muscle strength of legs was measured with Nicholas MMT, and the balance was measured with BIO-Rescue. We compared the dominant and non-dominant legs based on the results. The result, indicated no statistical difference on balance and muscle strength between dominant and non-dominant legs(p>.05). The results of this study will be helpful in setting the effective treatment direction and treatment level, and in controlling posture, balance and motor function.

Feeding effects of the honeybee pollen products from both domestic, China, Spain and mixture of different origin on the colony development of earth bumblebee, Bombus terrestris L., were surveyed to evaluate efficient nutritional resources for commercial bombiculture in Korea. As the results, the domestic pollen was most effective to achieve high rates of oviposition (88%), colony foundation (70%), and queen production. While feeding with domestic pollens during the egg-laying period, and domestic+Chinese mixture (5:2) during the breeding period (Plot-2), it revealed high oviposition rate of 75%, colony foundation of 65%, and large numbers of adult queen production, indicating its suitability for generation subculturing. In the Plot-3, the same high oviposition rate (75%) was obtained except for feeding with the domestic+Chinese mixture (2:5) during the breeding period, which produced large number of workers.

We performed a survey for flavivirus infection and distribution of Aedes albopictus that known as Zika and Dengue virus vector using black–light trap and BG-sentinel trap around urban area in Korea. Mosquitoes were collected in 27 cities during March to November (twice a month) year 2016. Total numbers of mosquitoes collected 102,102 including 19 species 8 genera during collecting period. Total 21,467 Ae. albopictus was collected that 20,961(24.3%) by BG-sentinel trap and 506 (3.2%) by Black-light trap in urban area. Trap index(trap/night) of Ae. albopictus was showed highest in Hamyang (TI:992.3) and lowest in Taebaek (TI:0.3) there was only collected by Black-light trap. A total of 894 pools from all collecting Ae. albopictus were performed a Flavivirus detection. Flavivirus was not detected during study period. This study may provide basic information for surveillance of imported diseases (include Zika virus) and vectors in Korea.

The purposes of this study were to examine the slacks purchases and wearing satisfaction among old-aged women who were highly dissatisfied with their bodies and fit due to physical changes and to provide some basic data needed to develop slacks patterns to meet their needs. A survey was taken among 223 old-aged women aged 60～79 living in Seoul. Using the SPSS 12.0 program, the collected data were analyzed in descriptive statistics, t-test, and crosstab. The result were as follows: the most used place for them to shop slacks was a market(including the Dongdaemun and Namdaemun market), which was followed by a department store and a discount store in the order. As for their preference for slacks according to age, those who were in their sixties most preferred straight-line slacks, while those who were in their seventies semistraight-type slacks. As for fit for each body part according to age, there were significant differences only in crotch length. Those who were in their seventies were more dissatisfied with crotch length than those who were in their sixties, feeling that crotch length was short. As for their experiences of repair after purchasing a pair of slacks, 82.5% said they had such an experience. Most of the repairs with length, waist and slacks width involved in size reduction.

Although trisomy 16 is commonly detected in spontaneous abortions and accounts for over 30% of cases of autosomal trisomy detected after spontaneous abortion, trisomy 16 mosaicism is rarely detected by amniocentesis in the second trimester. Here, we report a case of level III trisomy 16 mosaicism (47,XX,+16[8]/46,XX[31]) diagnosed by cytogenetic analysis of independently cultured amniotic fluid cells. The female baby was delivered at full term with low birth weight and intrauterine growth retardation, and interestingly, her karyotype was normal (46,XX). Given the difficulty in predicting the outcomes of fetuses with this mosaicism, it is recommended to inform the possibility of mosaicisms including this trisomy 16 mosaicism during prenatal genetic diagnosis and genetic counseling for parents.

경기도농업기술원 선인장연구소에서는 다육식물 내수시장 확대를 위하여 1998년부터 국내의 재배농가와 종묘업체로부터 유전자원을 수집한 후 2001년부터 2009년에 걸쳐 교배 및 계통선발을 하고 3회의 특성검정을 거쳐서 꽃기린 신품종 ‘파노라마’를 육성하였다. 기존 꽃기린 품종은 포화엽색이 적색, 분홍색 등 단색인 품종이었으나 새로 육성된 ‘파노라마’ 품종은 포화엽색이 녹색과 분홍색(RHS color chart 135B+54C)이 어우러진 복색이면서 고급스
