접목 방법이 포도 '캠벨얼리' /3309C 묘목 생산에 미치는 영향
박재현,박규현,사공동훈 한국환경농학회 2024 한국환경농학회지 Vol.43 No.-
n grape nursery stock production, grafting success and nursery quality depend on the grafting materials, method, attention paid to grafting, grafting time, ambient conditions, and post-transplanting management. Recently, various grafting methods have been employed in grapevine propagation. This study aimed to determine the most effective grafting methods for producing high-quality grape nursery stock of ‘Campbell Early’/3309C. Grafting operations were conducted in early April using four grafting techniques, i.e., tongue grafting, veneer grafting, cleft grafting, and omega machine grafting. The data showed that the omega machine grafting was fast and yielded a high proportion of nursery stock for sale. Tongue grafting resulted in the highest grafting success, tree height, and percentage of nursery stock for sale and special grade nursery stock. The veneer grafting produced a high shoot diameter and a low percentage of low grade (unsaleable in Korea) nursery stock. The percentage of low-grade nursery stock and the expected yield of low-grade nursery trees were high in both tongue and cleft grafting. Based on the results from this study, the most effective grafting method of grape ‘Campbell Early’/3309C nursery stock in the nursery production company was the veneer grafting or omega machine grafting.

대목별 DMSO (Dimethyl sulfoxide) 및 IBA (Indole-3 butyric acid) 처리농도가 포도 ‘흑보석’ 포트묘 생산에 미치는 영향
박재현,사공동훈 한국환경농학회 2024 한국환경농학회지 Vol.43 No.-
This study was conducted to investigate the effect of indole butyric acid (IBA) alone and in combination with dimethyl sulfoxide (DMSO) on the rate of grafting take, rooting, sprouting, grafting success and yield of nursery stock for sale of grape ‘Heukboseok’ potted nursery stock that were cutting-grafted to various rootstocks. This experiment was composed three factors. 1st factor is eight types of rootstocks as 18808, Teleki 5C (5 C), Teleki 8B (8 B), Millardet et Grasset 101-14 (101-14), Couderc 3306 (3306 C), Couderc 3309 (3309 C), Selection Oppenheim 4 (SO 4), Riparia Gloire de Montpellier (RG). 2nd factor is three levels of DMSO concentration as 0%, 5%, and 10%. 3rd factor is three levels of IBA concentration as 500, 1,000, and 1,500 mg/L. The grafting was performed in the end of March with the omega machine grafting. DMSO and IBA were applied through thirty seconds dip to the rootstock base. The data showed that the rate of grafting take, rooting, and sprouting were the highest in the 101-04, 3309 C, and 18808 rootstocks, respectively. The rate of grafting success was the highest in 18808 rootstock, and the rate of yield of potted nursery stock for sale of 18808 and 3309 C were higher than other rootstocks. The DMSO concentration was correlated to the rate of grafting take, sprouting and grafting success. However, the IBA concentration was not correlated to the rate of sprouting, grafting success and yield of potted nursery stock for sale. Based on the results from this study, the 3309 C rootstock had the highest graft compatibility with the ‘Heukboseok’, and the combination effect of DMSO and IBA were different by the rootstock.

세포사멸 조절에서 PI3K-PTEN-PKB/Akt 신호전달계의 역할
박재현,최영현 대한암예방학회 2008 Journal of cancer prevention Vol.13 No.3
Recently, the understanding of protein kinase B (PKB) activation and mechanisms for promoting cell survival has expanded rapidly. Several PKB substrates involved in apoptopsis have been described and many processes inhibiting cell death have been identified. In this context, the mitochondrion appears to be the key organelle in which PKB drives its anti-apoptotic activities. Additionally, by modulating transcription factor activity or inhibiting nucleus condensation/fragmentation, PKB interferes with upstream mitochondrial cell death signals, but it also maintains mitochondrial integrity by reinforcing the roles of key players acting on mitochondrial membranes. Moreover, caspase activity, which represents mitochondrial downstream events in the apoptotic process, can be prevented by PKB in different ways. More recent several studies have shown that mitochondria can also be fragmented in cells that normally undergo programmed cell death, supporting the notion that mitochondrial remodelling plays an important role in the process. The function of PKB is still not clear and further investigations of its possible role as a modulator of mitochondrial dynamics are required. This could lead to a major breakthrough in our understanding of PKB functions in cell survival and to the generation of powerful tools for cancer therapy. (Cancer Prev Res 13, 153-161, 2008)

Background: The most crucial factor in hair transplantation for male pattern baldness (MPB) patients is the efficient utilization of the donor–recipient ratio. However, there is no known factor that scientifically predicts the rate of progression of alopecia or indicates a permanently safe donor area. Methods: The study considered 1,008 Korean adult males with MPB; of these, it excluded 56 males with an absence of parietal whorls (PWs). The authors investigated the distance from the vertical bimeatal line (VM) to the PW, from the PW to the upper border of the helical rim (HR), and the distance from the PW to the occipital fringe (OF) in 952 subjects with a PW. Furthermore, we examined the distance from the PW to the OF considering the duration of alopecia and age in 322 subjects with vertex alopecia. Results: The distance between the VM and PW varied from 1.5 to 11 cm, with an average distance of 6.25 cm. The PW–HR distance ranged from 3.4 to 17.5 cm, and the average distance was 7.79 cm. The PW–OF distance ranged from 0.5 to 5.5 cm, and the average distance was 2.37 cm. Conclusions: For the PW, very large variations existed in the vertical direction. The position of the PW could predict the progression range of the total alopecia of the vertex. Alopecia mostly progresses within 6 cm of the PW toward the occipital side.

En France, s'il y résistance de l'exécution ou l'inertie de l'administration, le requérant a la faculté d'introduire un nouveau recours pour excès de pouvoir. Quand elle n'exécute pas la chose jugée, le bénéficiaire du jugement peut obtenir l'annulation des décisions qui la méconnaissent, ainsi que des dommages - intérêts en réparation du préjudice. On appelle cas d'annulation les diverses formes d'illégalité. Selon la classification traditionnelle, l'illégalité peut avoir l'incompétence, le vice de forme, le détournement de pouvoir, la violation de la loi. Toutefois, la décision de l'annulation n'équivaut pas nécessairement à la protection de l'administré, car en réalité un jugement d'annulation n'entraîne pas l'octroi d'une mesure souhaité par l'administré justiciable. Pour que l'annulation ait un effet réel, le juge administratif devrait prononcer l'injonction. L'administration doit tirer toutes les conséquences de la chose jugée, car le juge administratif ne peut ni se substituer à l'administration, ni ordonner aux agents publics de prendre telle ou telle autre décision, ni modifier les actes de l'administration. En Corée, le législateur a permis au requérant de choisir entre le recours administratif et le recours contentieux pour résoudre ce problème. Le recours administratif pour l'exécution de Corée contribuera à résoudre la question de la séparation des pouvoirs. Le juge coréen n'a pas de pouvoir d'injonction. Il faudrait lui donner le pouvoir d'injonction comme c'est le cas en France.
