The males of cryptic mealybug, Pseudococcus cryptus, were attracted on trap baited with or without a synthetic sex pheromone. The attractiveness of sex pheromone trap was higher than yellow-color sticky trap, but both phenologies were similar. There was a positive relationship between mean density of 2nd nymph to adult cryptic mealybug and the density of the male caught on trap. The density of cryptic mealybug per tree was higher correlated with yellow-color sticky trap than sex pheromone trap. The pattern of cryptic mealybug male occurrence had two to three cohorts in a generation resulted from overwintering stage. The maximum occurring time of 1st to 2nd nymph stage could be estimated from the peak time of trap catch by effective temperature accumulation. The higher and lower threshold temperature was estimated as 10.9 and 32.6℃, respectively and its thermal constant was 360 degree-day. The cryptic mealybug parasitoid, Anagyrus sp., which was first recovered in Jeju in 2009, was well attracted on yellow-color sticky trap. There was a high correlation between the density of Anagyrus sp. and of cryptic mealybug males caught on trap.

The damage of citrus fruit by yellow tea thrips, Scirtothrips dorsalis Hood, was first confirmed in 2008, and has since been one of the serious pests of citrus in Jeju. This was reported on damage symptom on tangor cultivar, Setoka (Tangor Norin No. 8) fruits cultivated in a greenhouse and the characteristic of spatial disttribution of S. dorsalis caught on yellow sticky traps was conducted in three commercial citrus orchards. The feeding habits by S. dorsalis cause rind blemishes on the navel part of fruit. The damage is characterized by being scarped and figure like covered cloud on satsum mandarine fruit, but on by a brown ring of rough russeting that occurs on navel part of Setoka fruit. The season of damage occurrence was from middle of June to late of July. There was a highly significant relationship between the average number of thrips per trap and the maximum number caught on a trap. The overall differences between the linear regression models obtained from mean-variance relationship for each surveyed fields were tested by type Ⅲ error and contrast method. The characteristic of spatial distribution of S. dorsalis was better described by Taylor's power law than Iwao's patchiness regression, and the dispersion index which is the slope (=1.72) of linear regression model showed the aggregated distribution pattern. The sequential sampling stop lines at fixed precision level of 0.20, 0.25 and 0.30 were calculated.

Some responses of cryptic mealybug, Pseudococcus cryptus, for a sex pheromone, [(1R,3R)-3-isopropenyl-2,2-dimethylcyclobutyl]methyl 3-methyl-3-butenoate, were studied to develop the applying strategy of sex pheromone trap for efficient monitoring and control-time decision in citrus orchards grown in greenhouse for 2 years (2007-2008). The optimal concentration of a sex pheromone was 1.0㎎ per hexane 100㎕ in a using pheromone lure. There was no significant effect of the attraction of male adults among different colours (white, blue and yellow) of plate-type trap baited with sex pheromone. The more male adults were attracted, as the distance of a pheromone trap form a citrus tree infested with cryptic mealybug was closer. The male adults were caught to sex pheromone trap from middle April to late November, and its peak period was the middle of July. The thermal constant for the next attraction was about 640 degree-days (lower threshold temperature=12℃) after confirmed the first attraction of male adults. The optimum control time for cryptic mealybug after the first attraction of male adults were confirmed was estimated as 450 to 500 degree-days.
Development and Current Situation of the Constitutional Adjudication in Korea
( Dong Heub Lee ) 서울대학교 법학연구소 2012 서울대학교 法學 Vol.53 No.2
After having gone through the inactive and sometimes merely ornamental forms of constitutional adjudication systems such as the Constitutional Committee or the American type judicial review system in the past, the Republic of Korea finally established the Constitutional Court in 1988. And, different from its predecessors, the Constitutional Court has been known for its active and successful performance in adjudicating constitutional matters, as the last resort of upholding the Constitution and protecting fundamental rights of the citizens. However, there are also some obstacles that should be hurdled by the Court, such as the issues related to its competence and jurisdiction, including lack of jurisdiction over the election disputes, lack of competence of constitutional review of statutory legislation in abstracto and no power to adjudicate the constitutional complaint against ordinary court`s judgments, and the issues related to the process of nomination and appointment and term of Justices. In order to solve these problems, the Constitutional Court must examine in depth these issues and make necessary improvements. This paper reviews 1) the institutional foundations of constitutional review in Korea, including current constitutional adjudication model and historical and legal reasons for its adoption and relations between the Constitutional Court and ordinary courts; 2) status and composition of the Constitutional Court of Korea, including qualifications, terms of Justices, possibility of their reappointment, procedure for nomination and appointment of Justices and guarantee of their independence; 3) jurisdictions of the Constitutional Court such as constitutional review of statutory provisions, adjudication on constitutional complaint, adjudication on competence disputes between state agencies, between state agency and a local government or between local governments, adjudication on the dissolution of political party and adjudication on the impeachment of high public officials; and 4) binding effect of the Court`s decisions on the Legislature, the ordinary courts and on the Executive. Also, in its last part, this paper introduces several important cases in practice concerning civil liberties, social rights in pursuit of social justice, other fundamental rights and principle of equality for protecting women or particularly vulnerable minorities.

Mullerian inhibiting substance (MIS), also called anti-Mullerian hormone (AMH), is a member of the transforming growth factor-β super-family of growth and differentiation response modifiers. It is produced in immature Sertoli cells in male embryos and binds to MIS/AMH receptors in primordial Mullerian ducts to cause regression of female reproductive structures that are the precursors to the fallopian tubes, the surface epithelium of the ovaries, the uterus, the cervix, and the upper third of the vagina. Because most gynecologic tumors originate from Mullerian ductderived tissues, and since MIS/AMH causes regression of the Mullerian duct in male embryos, it is expected to inhibit the growth of gynecologic tumors. Purified recombinant human MIS/AMH causes growth inhibition of epithelial ovarian cancer cells and cell lines in vitro and in vitro via MIS receptor-mediated mechanism. Furthermore, several lines of evidence suggest that MIS/AMH inhibits proliferation in tissues and cell lines of other MIS/AMH receptor-expressing gynecologic tumors such as cervical, endometrial, breast, and in endometriosis as well. These findings indicate that bioactive MIS/AMH recombinant protein should be tested in patients against tumors expressing the MIS/AMH receptor complex, perhaps beginning with ovarian cancer because it has the worst prognosis. The molecular tools to identify MIS/AMH receptor expressing ovarian and other cancers are in place, thus, it is possible to select patients for treatment. An MIS/AMH ELISA exists to follow administered doses of MIS/AMH, as well. Clinical trials await the production of sufficient supplies of qualified recombinant human MIS/AMH for this purpose.
