Bilateral cleft lip reconstruction can be performed in one-or two-stages. The choice depends on the surgeon's proficiency and experience. However the type and severity of the cleft must be considered. Complete or incomplete symmetric, bilateral clefts in which the premaxilla is within the alveolar arch or slightly protruded can be successfully treated with simultaneous lip reconstruction on both sides. There are some advantages that one-stage lip reconstruction facilitates creation of a symmetric and balanced lip, retraction of protruding premaxilla and the parent's psychologic satisfaction. However, there are some disadvantages such as micrognathia of the upper jaw by severe scar formation and poor adaptation of flap margins by severe tension. The surgeon must be able to judge and exploit the advantages offered by one-stage approach. We present the case report of one-stage reconstruction of primary bilateral cleft lip with literature reviews.

The sweet potato whitefly, Bemisia tabaci (Gennadius, 1889) (Hemiptera: Aleyrodidae), is one of the most important agricultural pests by direct feeding and begomovirus transmission in the world. B. tabaci species complex consisting of about 30 species worldwidely has been mainly distinguished by molecular methods because of difficulties detecting morphological differences. In Korea, distribution of two exotic groups, the Mediterranean (Q biotype) and the Middle East-Asia Minor 1 (B biotype), were confirmed by comprehensive molecular methods in 2012. Of them, the Q biotype as a vector of Tomato yellow leaf curl virus (TYLCV) has caused significant crop yield losses. Tobacco leaf curl virus (TbLCV), one of four begomoviruses in Korea, was first reported in 2011. It damaged, although not frequent, to greenhouse tomatoes at Iksan, Gimje, Sunchang, and Jeju. The vector transmitting TbLCV, however, is not known yet. In this study, we sampled an unknown B. tabaci populations on leaves of the Japanese honeysuckle (Lonicera japonica) at Iksan in outdoor conditions. PCR analysis revealed that some populations were infected with TbLCV. We identified an unknown indigenous genetic group named as JpL and clarified its phylogenetic relationships based on nucleotide sequences of mitochondrial cytochrome oxidase I gene.

This experiment was conducted to compare the fruit yield and quality of the boxthorn(Lycium chinese Mill.) landraces grown in the northern and southern regions. The ripening stage of northern landraces was four to seven days earlier as compared with sonthern landraces. The northern landraces had better for agronomic characters including stem lenth and diameter than the southern landraces, and had small and dark green leaves,and Sharp thorns,but the southern ones had large and light green leaves. Haenam landrace had not thorns. The northern landraces were more susceptable to antracnose than the southern one, and there was no difference in mite resistance between the landraces. The phe photosynthesis abilityof northern landraces were higher than that of southern ones at early growth stage(by mid-June), but vice versa after early Juld. The northern landraces had much more dryweight and leat area than the southern ones. It was assumed that the differences among landraces were mostly due to the characteristis of each landrace rather than due to the regions where each landrace had been grown. The extract content of Kwangju iandraec was higher than that of Daejeon landrace. The higher amount of extracts of the Kwangju landrace might be due to the daily high temperature and more sunshine in the Kwangju area.

This experiment was conducted to investigate the inorganic matter of leaf, Betain content of root organic matter of fruit and fruit extracts according to the various growing stage. Also, there were the studies on the relation between various fertilizer and its components and obtained the basic data for breeding good high yielding varieties. Varieties used in this experiment were 29 native varieties collected in Korea and oversea and 9 mutant species and planted at Daejeon, Chungnam in 1986. The inorganic matter of leaf and organic matter obsorption of fruit, N and Protein, P₂O₅ and Fat, and K₂O and Carbohydrate significant positive correlation. The releation between fat content and fruit extracts showed significant positive correlation. And there was significant negative correlation between carbohydrate, and protein content and extracts. The content of extracts and fruit yield of Japanese-2 variety was the highest of all and Lycii cortex yield and Betain content of variety treated with Colchicine 0.1% was the highest of all. And than, these varieties could be promising variety to use for breeding high yielding variety.

This experiment was conducted to investigate the physiological and ecological characteristics, and obtain the basic data for breeding disaster resistance and high yielding varieties at Daejeon, Chung Nam from 1984 to 1986. Varieties used in this experiment were 29 native varities collected in Korea and oversea and 9 mutant species treated with Co 60 and Colchicine. Dry fruit yield of Japanese-2 variety was 108Kg per 10a and 56% increased compared with standard cultured variety. Iycii cortex yield was 7.9Kg per 10a and increased 259% with Colchicine treatment. As the photosynthesis from May to August and R.G.R. treated with Co 60 had been high, the growth and development was posperous but flowering time was delayed 7-15 days. Also, as the number of flowering but per plant had been scarce, dry fruit yield was decreased 32% compared with Cheongyang variety. Yearly differences of principal characteristics in upper and lower parts was small but varietal difference of principal characteristics was obvious and varietal heritability was high.
Record of Thrips setosus Moulton (Thysanoptera: Thripidae) in Korea damaging to leaves of Hydrangea

Thrips setosus Moulton, 1928 (Thysanoptera: Thripidae), one of the Tospovirus vectors, was found at a commercial greenhouse in Korea. It damaged to leaves of hydrangea (Hydrangea macrophylla). The thrips widely distributes in Japan, being regarded as its origin. Recently, it invaded in Europe such as the Netherlands, France, and Germany. Unlike Japan, it was found on Hydrangea plants in European countries. In Korea, the thrips was recorded in 1974 by Woo. However, examination of voucher specimens reveals that the record is not true. According to the collection data since 2000, its distribution in Korea is rarely limited in Jeonbuk and Jeju. For identification, representative morphological characteristics and COI barcoding results are provided with possibility of introduction from Europe.
