  • There are no standard consensus about treatment results and prognostic factors based on randomized trials for benign vocal fold lesion. Currently, voice therapy is the treatment of choice for vocal nodules, and laryngomicroscopic surgery is for vocal polyps. There are no strong evidences to support it, based on randomized controlled trials, But, it's just a consensus among laryngologist. Considering the pathophysiology of benign vocal cord lesions, cognitive behavioral therapy that corrects the patient's bad voice habits and improves their vocal hygiene could be most important factor for treatment outcomes.

  • Adenoviral vector(AdV) has been the most widely used viral vector for delivering an exogenous therapeutic gene to human. As of this date, more clinical trials utilize recombinant AdV to treat cancer and monogenic inherited disease as well as vaccine applications. However, the number of clinical trials had dropped markedly following the tragic death of a patient ongoing an AdV therapy for the treatment of an ornithine transcarbamylase deficiency(OTCD). This review is an attempt to provide the information on toxicity generated by AdVmediated gene transfer. It would serve as a sobering reality to researchers and clinicians exploring the use of AdV, as to the complications involved in human application.

  • Nine herbicide products (fluazifop-p-butyl, clethodim, MCPA-sodium, 2,4-0 amine, chlorthal dimethyl, diquat, glyphosate, ethalfluralin and oryzalin) were evaluated for use on ginseng (Panax quinquefolius). Products varied in their ability to suppress weeds and certain materials were phytotoxic to ginseng in some trials. Chlorthal dimethyl (broadleaf weeds), MCPA-sodium (broadleaf weeds), fluazifop-p-butyl (grass weeds), and clethodim (grass weeds) were found to be effective as weed control agents and did not adversely affect ginseng growth. Other products tested were either not efficacious or were phytotoxic to ginseng in some trials. Weed populations were mainly introduced into the planting sites via the straw mulches used in ginseng cultivation.

  • The accuracy of estimates of hydrodynamic coefficients can be increased by using sensitivity-maximizing inputs. In this study, sensitivity-maximizing actuator commands of a submersible, which are sequences of bang-bang type commands, were obtained using Genetic Algorithm (GA) optimization technique. By comparing the total sensitivity values, deduced actuator inputs were found to be superior to the other sea trials. Based on the sensitivity distribution of conventional sea trials and sensitivity distribution results through deduced input scenario a review of submersibles' manoeuvring equations of motion was conducted .

  • Sample size determination is very important part in clinical trials because it influences the time and the cost of the experimental studies. In this article, we consider the Bayesian methods for sample size determination based on hypothesis testing. Specifically we compare the usual Bayesian method using Bayes factor with the decision theoretic method using Bayesian reference criterion in mean difference problem for the normal case with known variances. We illustrate two procedures numerically as well as graphically.

  • Objectives To evaluate the evidence supporting the effectiveness of Chuna manual therapy for primary insomnia. Methods The researcher conducted search across the 3 electronic databases (Pubmed, CAJ and Oasis) to find all of randomized controlled clinical trials(RCTs) that used Chuna manual therapy as a treatment for primary insomnia. Results Four RCTs met inclusion criteria. The meta-analysis showed positive results for the use of Chuna manual therapy in terms of the PSQI when compared to medication treatments alone. Positive results were also obtained, in terms of the PSQI, when comparing Chuna manual therapy combined with acupuncture therapy to acupuncture therapy alone, but was not statistically significant. Conclusions The review found encouraging but limited evidence of Chuna manual therapy for primary insomnia. We recommend clinical trials which compare the effectiveness of Chuna manual therapy with usual care to obtain stronger evidence without the demerits of trial design.

  • In a simulated seawater aquaculture system, effects of different operating factors like the superficial air velocity (SAY), hydraulic residence time (HRT), protein concentration and foam overflow height on the removal of total suspended solids (TSS) by a foam fractionator, with 20 cm diameter and 120 cm height, were investigated. This experiment was performed on batch and consecutive modes for different combinations of the tested factors, using synthetic wastewater. In 5 consecutive trials, TSS concentration in culture tank water decreased faster, when the foam fractionator was operated at higher SAV and lower HRT. In batch trials, with increasing SAV, TSS removal rate increased, but decreased with increasing HRT. Higher protein concentration in the bulk solution resulted in higher TSS removal rate. TSS concentration in the collected foam condensates increased but the foam overflow rate decreased with increasing foam overflow height. Foam fractionation was effective for removing TSS in seawater aquaculture systems and its performance largely depended on the operating parameters, especially superficial air velocity.

  • The concept on idiopathic pulmonary fibrosis (IPF) pathogenesis has progressed from chronic inflammation to aberrant wounding healing and even more to the current paradigms of a multifactorial and heterogeneous disease process. Despite the growth of clinical trials for IPF, most of the results, including N-acetylcysteine combination, warfarin, and bosentan, were disappointing. On the other hand, there have been a number of important developments; the foremost is the licensing of pirfenidone in Europe and Asia. In this article, we briefly review the recent knowledge of pathogenesis of IPF. We also summarize the recent clinical trials regarding the management of IPF.

  • 1. The trials were planned to test seven different fungicides for the control of Early blight of potato during the period of 1962 and 1963. 2. All of fungicides tested in the trials were considerably effective to control the disease, as the result of 4 applications which was done in one week intervals from early of June in 1963. All treatments were effective enough to make significant differences from the untreated. Especially, Dithyane M45, Difolatan and Dithane M22 showed satisfactory control even though no significant differences were obtained among them. Besides the three treatments, Bordeaux Mixture were relatively effective.

  • To develop a new ginseng varieties with good quality and high yielding, a lot of individual ginseng plants were selected in the farmer's fields in 1972. Among them, a promising line, 7259-3-1, has been developed through comparative cultivation of several lines selected with pure line separation of local races in Korea Ginseng '||'&'||' Tobacco Research Institute. Preliminary and advanced yield trials were performed for 8 years. It was then designated as "KG 101" and tested in the regional yield and adaptation trials for 10 years (1981-1990). KG101 has a green stem with light violet and orange-yellow fruit and flowers 3-7 days later than local race, Takyungjong. Taproot of KG101 was longer than local race Jakyungjong, and root yield of KG101 was 9% higher than local race Jakyungjong. In red ginseng quality, the rates of Chun-Jeesam (Chun and Jee means 1st and 2nd grade, respectively) were 22.3% and 9.4% for KG101 and Jakyungjong, respectively. In these results, it was clarified that KG101 was superior ginseng line with good quality.y.
