  • 2001년 이후 2005년까지 북측의 씨감자 생산은 남북 협력으로 순조롭게 진행되어 일부는 이미 3급종자(G3)까지 공급되어 증식되고 있는 실정이다. 특히 씨감자 생산 체계의 상위단계인 조직 배양과 양액씨감자(G0) 생산에서는 성공적이었으며, 다음 단계인 1급(G1)$\sim$4급종자(G4)를 어떻게 무병, 격리 조건에서 감염율을 적게 유지, 증식, 관리하느냐에 달려 있다고 해도 과언이 아닐 것이다. 벌써 상위단게 씨감자 생산의 효과가 나타나기 시작하고 있어, 특히 남북한의 지속적인 협력이 절실하다고 할 수 있다.

  • Various centrifuge model tests on the pile foundations were performed to investigate fundamental characteristics of a pile-soil-foundation system recently, but it is hard to find numerical analysis results of a pile foundation system considering the nonlinear behavior of soil layers due to the dynamic excitations. Numerical analyses for a pile-soil system were carried out to verify the experimental results of centrifuge model tests. Centrifuge model tests were performed at the laboratory applying 1.5 Hz sinusoidal base input motions, and nonlinear numerical analyses were performed utilizing a finite element program of P3DASS in the frequency domain and applying the same input motions with the intensities of 0.05 g~0.38 g. Nonlinear soil properties of soil elements were defined by Ramberg-Osgood soil model for the nonlinear dynamic analyses. Nonlinear numerical analyses with the P3DASS program were helpful to predict the trend of experimental responses of a centrifuge model efficiently, even though there were some difficulties in processing analytical results and to find out unintended deficits in measured experimental data. Also nonlinear soil properties of elements in the system can be estimated adequately using an analytical program to compare them with experimental results.

  • Mushroom strains of Polyporales from the genera Coriolus, Trametes, Pycnoporus, Ganoderma, and Formitella were explored in terms of mycelial growth characteristics for the application of mushroom mycelia as alternative sources of materials replacing fossil fuel-based materials. Among the 64 strains of Polyporales, G. lucidum LBS5496GL was selected as the best candidate because it showed fast mycelial growth with high mycelial strength in both the sawdust-based solid medium and the potato dextrose liquid plate medium. Some of the Polyporales in this study have shown good mycelial growth, however, they mostly formed mycelial mat of weak physical strength. The higher physical strength of mycelial mat by G. lucidum LBS5496GL was attributed to its thick hyphae with the diameter of 13 mm as revealed by scanning electron microscopic analysis whereas the hyphae of others exhibited less than 2 mm. Glycerol and skim milk supported the best mycelial growth of LBS5496GL as a carbon and a nitrogen source, respectively.

  • Adipocyte differentiation is strongly associated with obesity, which causes metabolic disorders. In this study, we investigated the inhibitory effects of widdrol on 3T3-L1 preadipocyte growth and differentiation. Widdrol decreased lipid droplet accumulation and down-regulated adipogenic transcription factors such as C/$EBP{\alpha}$, C/$EBP{\beta}$, and $PPAR{\gamma}$. Widdrol blocked preadipocyte proliferation and differentiation through the inhibition of mitotic clonal expansion, which was accompanied by the failure of degradation of p21, a cyclin-dependent kinase inhibitor. Cell-cycle analysis clearly indicated that widdrol actively induces cell-cycle arrest at the G1-S phage transition, causing cells to remain in the preadipocyte state. Moreover, widdrol increased p21 expression and inhibited Rb phosphorylation in preadipocyte incubated in a hormone medium. Therefore, these findings clearly suggest that widdrol blocks preadipocyte growth and differentiation through the inhibition of mitotic clonal expansion by p21-and Rb-dependent G1 arrest and can be developed as a potent anti-adipogenic agent for reducing obesity.

  • Purpose: The purpose of this study was to evaluate the achievements of the project, and also to find out its strengths and weaknesses. Method: This evaluative study employed system theory and analytic techniques by using criteria which were relevance, appropriateness, adequacy, progress, effectiveness and satisfaction for input, process, output, and outcome of program. Study subjects were participants in the home health care program implemented in G public health center in Inchon metropolitan city in 2003. Results: Input factors including recruitment personnel, and support organization development were not adequately met for the program. However. the goal and objectives of the project were really appropriate for the community needs as well as government's policy. For the Process evaluation, home health care record form and computer data base had not progressed as scheduled, but overall program activities were finished on time. However, cooperation between organizations in the health center during service activity were not supportive. Managerial ability of program charged personnel about coordination and integration of team members was not affirmative. Output and outcome evaluation showed that people improved self care ability were 221 (17.5%). and 71 (5.62%) of subjects were moved into category of possible self-care. Client's satisfaction for this project showed a high degree. Conclusions: Based on the above results support organization and staff personnel for this program should be developed. Also, a community network of resources should be established and case management services should be focused continuously in community based home health care.

  • The Eclipsing Binaries Minima (BIMA) Monitoring Project is a CCD-based photometric observational program initiated by Bosscha Observatory - Lembang, Indonesia in June 2012. Since December 2012 the National Astronomical Research Institute of Thailand (NARIT) has joined the BIMA Project as the main partner. This project aims to build an open-database of eclipsing binary minima and to establish the orbital period of each system and its variations. The project is conducted on the basis of multisite monitoring observations of eclipsing binaries with magnitudes less than 19 mag. Differential photometry methods have been applied throughout the observations. Data reduction was performed using IRAF. The observations were carried out in BVRI bands using three different small telescopes situated in Indonesia, Thailand, and Chile. Computer programs have been developed for calculating the time of minima. To date, more than 140 eclipsing binaries have been observed. From them 71 minima have been determined. We present and discuss the O-C diagrams for some eclipsing binary systems.
