This study was conducted to develop the clonal propagation technique through in vitro culture using basal stem explants in Phalaenopsis hybrid grown in vitro. The highest frequency of protocorm-like body (PLB) formation was obtained when basal stem explants were cultured on VW medium containing 30g/L sucrose, 500 mg/L activated charcoal, 150 ml/L coconut water, 1 mg/L NAA, 5 mg/L 2iP and 2.5g/L gel rite. PLBs transferred to Hyponex medium were regenerated to plantlets. Plantlets transferred to plastic pots containing spagnum moss were developed and successfully acclimatized under greenhouse. The flower was bloomingly opened in plants regenerated from basal stem explants. The flower was not different from both mother plant and plant induced through clonal propagation of Phalaenopsis hybrid.

Allium wakegi Araki was grown at plant spacings of 5, 10, 15, and 20 cm to determine the effect of planting density on the growth and yield. Allium wakegi Araki plants grown at the 5 cm plant spacing had the lowest bulb diameter and bulb weight, while plants at the lowest density (20 cm spacing) had the highest bulb diameter, bulb number, bulb weight and fresh weight. In general, plants grown at narrower spacings produced significantly smaller bulb diameter and bulb weight, but resulted in the highest yields and plants per hectare and lower fresh weights per plant.

<B>Graphic Abstract</B> <P>The cover shows an image of fully rollable transparent nanogenerators synthesized using chemical vapor deposition grown large-scale graphene sheets as transparent electrodes and piezoelectric ZnO nanorod arrays. Sang-Woo Kim, Jae-Young Choi, and co-workers report on p. 2187 the electrical and structural stability of the nanogenerators, with excellent charge scavenging performance under external mechanical loads such as bending and rolling. This study shows that graphene-based nanogenerators are very promising for self-powered rollable transparent device applications. <img src='wiley_img_2010/09359648-2010-22-19-ADMA201090066-content.gif' alt='wiley_img_2010/09359648-2010-22-19-ADMA201090066-content'> </P>

Market Entry Strategies and Potential Projects of Electric Power Sector in Mozambique

본 연구에서는 모잠비크 전력산업의 최근 동향을 소개하면서 전력분야의 구체적인 유망 프로젝트를 살펴보고자 한다. 그리고 국내 기업의 모잠비크 진출전략을 모색하고자 한다. 모잠비크는 남북으로 길게 국토가 펼쳐져 있어 송전용량의 제약이 시급한 과제이며, 이를 해결하기 위해 남북간 송전선 건설 프로젝트를 가장 핵심적인 전력분야 과제로 추진 중이다. EDM은 다양한 발전 프로젝트를 제시하면서 해외투자를 유치하려고 하는데, 모잠비크 전력분야에 대한 투자는 모잠비크의 국내 수요 보다는 주변 남부 아프리카 국가 특히 남아공화국의 전력수급 사정을 감안하여 결정할 필요가 있다. 또한 자원개발과 연계한 진출전략 수립 시에도 사회기반시설이 부족한 점을 감안하여 모잠비크에 적합한 전략을 마련해야 한다. 모잠비크 전력부문 진출은 본문에서 제시한 다양한 제약 요소에도 불구하고 새로운 시장개척을 통해 자원협력을 강화한다는 차원에서 보다 적극적인 접근이 요구된다. 특히 국가 리스크가 높은 점을 감안하여 민간기업의 진출에 대해 정부가 일정 부분 위험을 분담해 주는 전략도 필요하다. In this study, we examined the current status and the specific promising projects in the power sector of Mozambique, and explored the strategy to enter the Mozambican power market. As Mozambique stretches from north to south, she holds power transmission capacity constraints. To solve this problem, the construction of north-to-south transmission line is being pushed forward as the most crucial task in power sector. EDM tries to attract foreign investment by proposing various power projects, but the decision of investment in the Mozambican power sector needs to consider power supply conditions of the southern African nations, particularly of South Africa. Since transportation infrastructure to the coast line is not built properly, the feasibility of package deal approach should be reviewed comprehensively. In spite of various constraints, entering the power sector of Mozambique needs a more aggressive approach in terms that it will strengthen resources cooperation through pioneering new markets. In particular, considering the high country risk, a strategy would be necessary that the Korean government takes a portion of risk for private companies.

BackgroundAcute leukemia (AL), not clearly assigned to myeloid, B-lymphoid, or T-lymphoid lineage, is classified as either biphenotypic acute leukemia (BAL) based on the European Group for Immunological Classification of Leukemias (EGIL) or acute leukemia of ambiguous lineage (ALAL) encompassing acute undifferentiated leukemia (AUL) and mixed-pheno-type acute leukemia (MPAL) based on the World Health Organization (WHO) criteria. MethodsMedical records of children newly diagnosed with BAL or ALAL, based on the EGIL or the 2008/2016 WHO criteria, respectively, admitted at Chonnam National University Hospital in 2001‒2017 were retrospectively reviewed.ResultsTwelve (3.2%) of 377 AL patients satisfied the BAL or ALAL definitions based on the EGIL or the WHO criteria, respectively. Among 12 patients including 11 with BAL and another with undefined case based on the EGIL criteria, 7 (1.9%) had ALAL based on more stringent 2016 WHO criteria (AUL, 2; MPAL, 5). One patient had MPAL with t(9;22)(q34;q11.2), BCR-ABL+, and two had MLL gene abnormality. ALL-directed regimen was associated with better complete remission rate compared with AML-directed regimen (100.0% vs. 16.7%; P=0.015). The 5-year overall survival (OS) and event-free survival (EFS) were 51.1±15.8% and 51.9±15.7%, respectively. AUL was associated with poor OS and EFS compared with MPAL (0.0% vs. 75.0±21.7%; P=0.008).ConclusionDue to the rarity of the cases, future multicenter, prospective studies incorporating large number of cases are urgently warranted to identify the clinical, biologic, and molecular markers for the prediction of prognosis and determine the best tailored therapy for each patient.

ABSTRACT: The aim of this study was to elucidate the precise anatomy of the perforating branch of the superficial temporal artery in relation to subcutaneous forehead lift (SFL).Ten hemifaces of 6 fresh adult Korean cadavers were used in this study. In 4 hemifaces, following injection of red latex, dissection was performed. In 2 hemifaces, following injection of methylene blue solution into the perforator, the area of discoloration was observed. An artery perforating the frontalis muscle into skin of the forehead was identified in 18 foreheads of 9 patients who underwent SFL. Measurements were taken of the external diameter and the location of the perforator.Perforating branches originating from the frontal branch of the superficial temporal artery, perforating the frontalis muscle into skin of the forehead, were observed in all 10 of the dissected hemifaces. Thereafter, it was referred to as the perforating frontal artery (PFA). Skin of the ipsilateral mid-forehead was discolored by methylene blue solution. Most of the PFA (83%) was included in a circle having a radius of 8.9 mm. The center of the circle was located 40.5 mm from the midline on the x axis and 53.6 mm from the supraorbital rim (on the y axis). The center of the circle was located at 89.8% of the length of the midline to the lateral canthus (x axis) and 79.1% of the length of the supraorbital rim to the hairline (y axis).Plastic surgeons can use the PFA in order to achieve sufficient circulation of the skin flap. When surgeons are required to sacrifice the PFA in order to achieve flap mobilization, they can safely cauterize the PFA after isolation without causing accidental burn injury to the skin flap. In addition, the PFA might be useful in creation of local or distant flaps for reconstruction of the forehead or scalp.
